Ultrasonic excitation has been widely used in the detection of microcracks on metal surfaces, but there are problems such as poor excitation effect of ultrasonic pulse, long time to reach the best excitation, and difficult to find microcracks. In this paper, an adaptive ultrasonic pulse excitation device and infrared thermal imaging technology have been combined, as well as their control method, to solve the problem. The adaptive ultrasonic pulse excitation device adds intelligent modules to realize automatic adjustment of (...) class='Hi'>detection parameters, which can quickly obtain reliable excitation; the multidegree-of-freedom base realizes the three-dimensional direction change of the ultrasonic gun to adapt to different excitation occasions. When the appropriate ultrasonic excitation makes microcracks in the resonance state, the microcracks can be frictionated, which produce heat rise with the temperature. Then, the microcrack defect can be detected by the infrared thermal instrument through the different surface temperatures with imaging recognition method. Our detection experiments of the titanium alloy plates and the aluminum alloy profiles of marine engineering show that the method can get reliable detection parameters in a short time and measure the crack length effectively. It can be used in many aspects such as crack detection in mechanical structures or complex equipment operating conditions and industrial production processes. (shrink)

In order to use the framework of general system theory (GST) to unify the three mechanics subjects of classical mechanics, quantum mechanics, and relativistic mechanics, a new general system theory (NGST) is developed based on a new ontology of ether and minds as the fundamental existences in the world. Based on this new ontology, many fundamental concepts have been detected to be ambiguously defined nowadays and particularly lack of ontological support. In our previous work, some of the fundamental concepts such (...) as universe, world, time, space, matter, ether, mind, life, field, force have been redefined. The purpose of this paper is to clarify the concepts of energy, heat, work, entropy, and information in our NGST. This is an important and necessary step in the development of the NGST. (shrink)

This article addresses the question of whether an expectation of privacy is reasonable in the face of new technologies of surveillance, by developing a principle that best fits our intuitions. A "no sense enhancement" principle which would rule out searches using technologically sophisticated devices is rejected. The paper instead argues for the "mischance principle," which proscribes uses of technology that reveal what could not plausibly be discovered accidentally without the technology, subject to the proviso that searches that serve a great (...) public good that clearly outweighs minimal intrusions upon privacy are permissible. Justifications of the principle are discussed, including reasons why we should use the principle and not rely solely on a utilitarian balancing test. The principle is applied to uses of aerial photography and heat-detection devices. (shrink)

The detection of the number of extra–compact dimensions contained in some gravitational models is analyzed resorting to the discontinuity of the specific heat at the critical temperature of a Bose–Einstein condensate. It is shown that the function relating the number of particles and this discontinuity defines a segment of a straight line whose slope depends upon the number of extra–compact dimensions. The experimental feasibility of the proposal is also considered.

Context: The detection of objective reality, truth, and lies are still heated topics in epistemology. When discussing these topics, philosophers often resort to certain thought experiments, engaging an important concept that can be broadly identified as “the global observer.” It relates to Putnam’s God’s Eye, Davidson’s Omniscient Interpreter, and the ultimate observer in quantum physics, among others. Problem: The article explores the notion of the global observer as the guarantor of the determinability and configuration of events in the world. (...) It analyzes the consistency of the notion “global observer” from the standpoint of logic and philosophy, and discusses why application of this notion in some contexts poses challenges and appears to be paradoxical. Method: The paper uses conceptual methods of argumentation, such as logical and philosophical kinds of proof. Its key approach is the engagement of thought experiments. Results: The notion of a global observer is incoherent: “being global” and “being an observer” appear to be incompatible features. It is claimed that from the standpoint of global observation, there are no events occurring in the world. Furthermore, the indefiniteness of the world as a whole is asserted, which is related to the uninformedness of the global observer regarding the “true state of affairs.” “Global observation” turns out to be incompatible with the concept of the observer, blocking, as a result, the opportunity for a determinable configuration of events. It only makes sense to discuss local observations, which are limited to mutual observation or introspections, and not to assume the existence of some absolute truth, reality, or the state of affairs beyond the local observations. Constructivist content: The article emphasizes the role of the observer and observation. It opens up some problematic consequences of the core philosophical assumptions of globally observing existence. Referring to von Foerster’s and Luhmann’s idea that we can only speak reasonably about local observations, the paper argues that reality is neither external to nor independent of the observer. Implications: The paper could be productive for epistemic theories, theories of quantum physics, and theories of non-classical logic. (shrink)

Discussions related to the detection of objective reality, the truth and lie are still a heated topic in the domain of philosophical epistemology. While certain philosophical contexts and theories suggest that the notion "reality as an independent category" should not be engaged, instead, interpretations, including reciprocal, should be used, others hold it that philosophical discussion cannot continue without reference to the said notion. Different philosophers and scolars approach this problem from different angles. When discussing these topics, philosophers often resort (...) to certain thought experiments, engaging an important concept, which can broadly be identified as "the global observer." This concept has something in common with such concepts as the God's Eye, Omniscient Interpreter, Ultimate Observer (quantum physics), Agent of Logical omniscience (game theories), Ideal Observer (ethics and meta-ethics), God (analytic theology). Despite the abundance of works on the topic and scrupulosity of arguments, there still remain many uncertainties in such discussions, mostly related to a great number of logical paradoxes, associated with the problem.

In the heat of the Civil War, Abraham Lincoln made a speech in which he referred sympathetically to the Southern rebels. A member of the audience lambasted him for wanting to treat his enemies kindly when he ought to be thinking of destroying them. Lincoln's answer: "Why, madam, do I not destroy my enemies when I make them my friends?" Harshness and cruelty were to be banished from the moral imagination of the nation he was trying to save. The (...) late Jack Maple, a famously flamboyant but phenomenally effective former deputy commissioner of the NYPD, wrote that "the more information a detective has, the more creative, authoritative and effective he or she can be." Under attack in 2001, and then at war in Iraq in 2003, American law enforcement, intelligence and military really didn't have much information at first. They rounded up the usual suspects, but didn't know what usual meant. So they smacked people around, and that was always a bad idea, as Maple said: "Forget that smacking somebody around is illegal and just plain wrong, it's also the quickest way to ruin the chances of getting a statement of any kind." Professional interrogators talk about building empathy and dependence. Maple would get down on his knees and pray with a suspect if he thought that would work. But the best technique? "If you can get them to laugh, you'll get a statement. That's always true." Internal CIA documents reveal that empathy is also likely what got Abu Zubaydah to reveal how Al Qaeda planned 9/11 and its other operations. His torture brought nothing of real value, only the moral demeaning of his tormentors.... (shrink)

A looming deadline. A difficult situation at home. A heated phone conversation that redirects our attention. Certain features of our circumstances can be (at least partially) excusing; sometimes, agents who act wrongly in the face of circumstantial pressures are not (that) blameworthy for having done so. But we’re rather bad at detecting these factors that excuse others from blame. When put together, these two observations yield an under-appreciated problem: we fall short of procedural norms of blame in fairly systematic ways.

Around 96 percent of children with hearing loss are born to parents with intact hearing, who may initially know little about deafness or sign language. Therefore, such parents will need information and support in making decisions about the medical, linguistic, and educational management of their child. Some of these decisions are time-sensitive and irreversible and come at a moment of emotional turmoil and vulnerability (when some parents grieve the loss of a normally hearing child). Clinical research indicates that a deaf (...) child’s poor communication skills can be made worse by increased level of parental depression. Given this, the importance of reliable and up-to-date support for parents’ decisions is critical to the overall well-being of their child. In raising and educating a child, parents are often offered an exclusive choice between an oral environment (including assistive technology, speech reading, and voicing) and a signing environment. A heated controversy surrounds this choice, and has since at least the late 19th century, beginning with the International Congress on the Education of the Deaf in Milan, held in 1880. While families seek advice from many sources, including, increasingly, the internet, the primary care physician (PCP) is the professional medical figure the family interacts with repeatedly.The present article aims to help family advisors, particularly the PCP and other medical advisors in this regard. We argue that deaf children need to be exposed regularly and frequently to good language models in both visual and auditory modalities from the time hearing loss is detected and continued throughout their education to ensure proper cognitive, psychological, and educational development. Since there is, unfortunately, a dearth of empirical studies on many of the issues families must confront, professional opinions, backed by what studies do exist, are the only option. We here give our strongly held professional opinions and stress the need for improved research studies in these areas. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Evgeny Zamiatin's "The Cave"Timothy LangenEvgeny Zamiatin's short story "The Cave," like Fyodor Dosto- evsky's novel Crime and Punishment, has at its dramatic center a single criminal act, and as its philosophical preoccupation the reasons for and the results of that act. The act in "The Cave" is not murder but theft, the theft of scarce firewood from a downstairs neighbor. The result, unlike Dostoevsky's, is rapid detection, confrontation, (...) and then suicide. The reasons, however, are somewhat more complex, and as with Dostoevsky they reach beyond merely topical sensation to touch a paradox that lies close to the heart of human civilization.The immediate reasons are topical and simple enough. Martin Martinych and Masha live together on the brink of hypothermic death during the predictable cruelty of a Petrograd winter and the exceptional horror of the Russian Civil War. Nearly everyone in the city is freezing and starving, and the precariousness of existence has led people to trade the luxuries of civilized life for the barest essentials of physical survival. Books and sheet music shift imperceptibly from repositories of memory and culture into combustible objects good for a few more minutes of life-saving warmth. Favorite rooms are abandoned as not worth the cost of heating, and Martin Martinych sacrifices his conscience for a few scraps of wood. Indeed, Zamiatin prepares the crime at least as sympathetically as does Dostoevsky: the victim, Obertyshev, is every bit as dislikable as Dostoevsky's pawnbroker; he hoards his considerable supply of wood in total indifference to the suffering of his neighbors. Moreover, Mart's crime, unlike Raskolnikov's [End Page 209] in Crime and Punishment, hardly injures the victim, who seems to suffer a purely mental affront when some of his stash has been stolen. We would like to think that in Raskolnikov's place we would not commit his crime; in Mart's place, however, we might well be excused for following his example and filching a few sticks of wood from a man who doesn't need them.However, it is not an easy decision for Mart, and Zamiatin describes it as a battle between two Marts, bifurcated by the extreme deprivation of his circumstances into a purely animal Mart, a "caveman" who says only "I must," and another Mart clinging tenaciously in memory, a Mart who used to love the music of Scriabin and who now, standing before Obertyshev's ample woodpile, says "I may not." The caveman prevails, Mart brings the wood upstairs, and he and Masha enjoy a day of warmth. At the end of the day, the chairman of the housing committee confronts Mart, assuring him that he too detests Obertyshev, but advising Mart to return the wood or else face legal consequences. Alas, there is none to return. In despair Mart reaches for a vial of poison that he has apparently reserved for that moment when the suffering of life outweighs the hope—but Masha, who is further gone than he, insists on taking the single portion herself. She instructs Mart to go outside for a little walk while she does the deed. He does so, and here the story ends.Zamiatin was trained as an engineer and early in his career he worked both as a technical writer and as a writer of fiction, and so it is tempting see behind this story a mechanical vision of human existence that is something like a physical structure. The structure of human civilization, according to this view, is built on an essential framework without which the entire thing would collapse, and to which every other part of the structure must be sacrificed if need be. Physical existence is part of this framework: it is the precondition of any human civilization, and the ornaments of that civilization must when necessary be devoured to ensure the continued survival of human beings. The burning thirst of physical necessity must be slaked before we can irrigate the lush fields of beauty, kindness, and imagination. Books are for reading, but in some circumstances they are more valuable as kindling.In the writing of some psychologists—most notably Abraham Maslow—there appears a "hierarchy of human needs" that...

Air pollutants pose a threat to biodiversity throughout the world. This study was conducted to evaluate atmospheric element accumulation in Isparta city, including Gölcük Nature Park, located in the Western Mediterranean Region of Turkey. It is aimed to determine the air quality and potential pollutant sources in the region through lichen biomonitoring. Specimens of the epiphytic foliose lichen Physcia aipolia (Erh. ex Humb.) Fürnr. were sampled from 14 sites in the study area and analyzed by ICP-MS with reference material in (...) order to detect 11 trace elements; Al, As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, V, and Zn. The spatial distribution of these airborne elements in the study area was mapped. The results showed that the elemental sequence in terms of average concentrations measured was as follows: Ni >Cr >V >Fe >As >Al >Zn >Cu> >Cd >Mn >Pb. The results of cluster analyses of the elemental data indicated that the 3 major contaminants in the urban area were Cr, Ni, and V, probably due to the extensive use of coal in heating facilities and gasoline in vehicles. P. aipolia specimens accumulated maximal concentrations of As, Cr, Fe, Ni, and V in the northern and the southeastern localities surrounding the city, while Cd, Pb were most abundant in the eastern edge of Gölcük Nature Park. The pollution in Isparta city with heavy metal is worse than expected, mostly due to the extensive use of coal as fossil fuel. In addition, it seems to be associated with the city's topographic and climatic characteristics, e.g. inversion effects. (shrink)

My Back Is To A Life Passed. A year, maybe more, in liminal space. Waiting. For a vaccine. For better therapeutics. For a political climate to shift. All the while, the actual climate turns against us.The waters rise in the East. Fires rage in the West.My back is to a life passed. Retirement, just before the pandemic. Post-retirement and lockdown, simultaneous. A turn to a writing life—solitary, self-directed, coming at a time when my options are limited. My go-to places for (...) connection and inspiration—museums, coffeehouses, lectures, and readings—all off-limits. The natural world, my cathedral, also inaccessible. The fires rage, and the air is unbreathable.Over morning coffee, in our quiet house, the windows shut against dangerously high particulates and a darkened sky, I read an article by Julian Lucas in The New Yorker, “When a Virus Becomes a Muse.” He reviews the work of Hervé Guibert, the French writer who died from AIDS in 1991. Guibert focused on the body. His young, sexual body, with its confounding insistence. His failing body, ravaged by disease. AIDS was his muse, blasting him into a wildly creative few years, writing four books in the last three years of his life (Lucas).How will this virus, the novel coronavirus, serve as muse? The pandemic sets limits: Where can I go? Who can I see? I live within constructs and limitations imposed much like the rules of poetic form. Within those—the sonnet, the haiku—how is language wrought? How sharp, how bright, its expression? If I cannot hug you, how do I show my devotion? In my separate state, how do I live connection? I have a new expression. Mouth and nose covered, only my eyes showing, framed by glasses I need in order to see, I punctuate exchanges at the checkout counter, and with the health-check staff at the entrance to my daughter's physical therapy facility, by forcing my eyes into a warm, glad squint. I want them to beam. From people's responses—the moment of recognition, the tender mirroring, the body tilting to the side, eyes crinkled, head nodding—I can tell that the beam is working. It took time to develop this new way. I learned that I have to smile with my mouth, with my whole face, even when it can't be seen, for my feelings to show.Life, like art, requires structure, the boundaries of form. How to structure a day? It could be embodied. Filled. Wasted. Or used. My back is to a life where hours and minutes had a particular meaning. I am no longer expected at work by a certain hour, nor to put in three hours before my morning break. The collective future, where we tossed plans, goals, places we would see—again, or for the first time!—cannot be reached over the smoothed and worn stepping-stones of, say, weeks until a holiday. The broad swaths of the day become the new metric. The slow, mounting morning. A walk, or a longer one, before getting to the bulk of the day's writing. The noontime pivot, heat of the day rising, the birds quiet. Lunch, and a few chores. Essential errands. Medical appointments.The downslope of afternoon, with its nagging refrain, in the time you have left... The swirling, heated world. Greta Thunberg, 16 years old, sails from Europe to the United States to address a conference on climate change. She sails, rather than flies, so as not to add to her carbon footprint. It takes time, that voyage. She waits on deck while moving toward her future. The past recedes. The stormy Atlantic rises.Is it any clearer now that the food chain originates not in boardrooms but in hot fields, that the first essential worker drops from the back of a truck before sunup with a knife and a crate held in roughened, swollen hands?At night, sitting on the sofa, we watch television, the police procedurals that offer entertainment. Escape and relief. The day has passed. These are the rewards for getting through another day of uncertainty, managing the anxiety of risking exposure in order to get groceries and prescriptions and to bring my daughter to physical therapy. The TV detectives we favor work in teams as they interview suspects, talk to witnesses, confer with one another as they refine their theories and move photographs and bits of evidence around on the bulletin board. Our shows always tie up nicely in the end. In my life now, without the team or the interviews or the meetings that keep the detectives connected, I pretend that I am one of them, that my notebooks and plot maps and drawings and time lines are all clues to a mystery that I will solve. Despite my enervated state, I get up, I work, I look at and handle all the materials I have acquired. The day passes. Each night, a reward for getting through the day. Another day. Standing between worlds. Waiting. (shrink)

As the Cold War winds down and the atmosphere heats up, the environment is rising to the top of the global agenda. The number of refrigerators, not missiles, are what count now; the most urgent mission of the U2 spyplane is no longer detecting ICBMs on the ground in Russia, but ozonedepleting CFCs above the Arctic. Already, terms like “industrial disarmament” and “ecological security” are seeping into the mainstream political discourse.

Since the 1990’s the rise of China provokes heated debates in the West. Numerous politicians and scholars, who study contemporary political affairs, pose the question, which will be the new role of China in international affairs? Many Western observers presume that China will act as the Western powers did in the past, promoting policy of domination, enslavement and gaining profits at all costs. The Chinese declarations on peace, co-operation, mutual interests, and harmony are often considered empty words, a certain decorum (...) of “real politics”, as it had been often practised in the West. An inquiry into the Chinese political and intellectual traditions, almost unknown in the West, challenges such widespread opinions and fears. Of course, it is an open question to which degree the traditional Chinese concepts will determine contemporary policy, since China had been westernised in enormous degree.Nevertheless, attitude to war, struggle, and competition constitutes one of the principal characteristics of each culture and appears closely related to its structure of values. Such attitudes determine political concepts and systems, foreign relations, norms of social life, etc. The analysis of Western and Chinese civilisations demonstrates that in this respect they represented divergent orientations. In Erich Fromm’s typology of societies, the Chinese culture could be considered non-destructive but aggressive, whereas Western civilisation could be called aggressive and destructiveOf course, there were great differences both within Chinese and within Western civilisations. Local/regional cultures belonging to each of them had their own characteristics in respect to struggle, and one could also notice great changes in the course of their histories. In general, at the dawn of these two civilisations, both of them were more or less bellicose, although in the cultures of the Chinese Central Plain “avoiding struggle” traits could be detected quite early. Appreciation of peace and harmony eventually prevailed with the predomination of the Confucian ideology, although Taoism and other schools of thought also condemned struggle and war. On the other hand, in the Mediterranean the bellicose cultures and war-mongering states prevailed. The beginning of this “great divergence” could approximately be dated for the middle of the 1st millennium BC, and the civilisations of East Asia and Europe took the opposite courses in theirsocial and political development. Struggle constituted a fundamental principle in the Western vision of the world-order, and its crucial archetype constituted the eternal struggle of Evil against Good, with the eventual triumph of God, who embodies Good and forces of Light. The Chinese tradition promoted instead the vision of the universe as one giant organism based on the principle of harmony, where Yin complements Yang. Hence both civilisations adopted the dualistic concepts, but one was antagonistic, and the second—complementary.In the 19th century, when Asian nations faced the colonial conquests, many of them tried to protect their independence and modernise themselves. For this end they tried to adopt not only Western armaments and military skills, but also Western bellicose ideology and values. Japan was obviously the champion of such a militarist course, but there were similar tendencies in China as well. Such bellicose ideology reached its apex there during the famous Maoist Cultural Revolution, when class struggle and bellicosity was exalted. The triumph of the Western bellicose approach and rejection of the traditional native heritage marked the century 1860’s–1960’s in China. However, after the unimaginable sufferings of the World War I and II, of Nazism and of communism, the West started to revalidate its traditions condemning war and violence. People started to appreciate peace and co-operation within and among nations. The United Nations and the European Union had been founded for such purposes: to promote peace and co-operation. However, the condemnation of wars did not halt military confrontation of the states, and the West still cultivates political ideologies, which propagate the “proper order” based on competition and struggle. Hence the concepts of multi-party democracy and of free market could serve as hallmarks of the West. In China, since the end of the 1970’s step by step the ancient ideological traditions have been appreciated again and the new concepts of peaceful and harmonious development evolved. At the beginning of the 21st century the Chinese leaders elaborated a new ideology of both harmonious domestic and international order aiming at peaceful development based on co-operation. Of course, there are still vivid the remnants of the previous Western-type approach of the brutal competition and of aggressive foreign policy.Notwithstanding divergent tendencies inside each of these civilisations, in general they both approach each other again, but this time in a common search for peace, cooperation and harmonious development. Their interpretations obviously differ, since in China such concepts are traditional, but rather new in the West, and in various respects both sides have different values and ideals. (shrink)

Virtual reality provides an immersive 360-degree viewing experience and has been widely used in many areas. However, the transmission of panoramic video usually places a large demand on bandwidth; thus, it is difficult to ensure a reliable quality of experience under a limited bandwidth. In this paper, we propose a field-of-view prediction methodology based on limited FoV feedback that can fuse the heat map and FoV information to generate a user view. The former is obtained through saliency detection, (...) while the latter is extracted from some user perspectives randomly, and it contains the FoV information of all users. Then, we design a QoE-driven panoramic video streaming system with a client/server architecture, in which the server performs rate adaptation based on the bandwidth and the predicted FoV. We then formulate it as a nonlinear integer programming problem and propose an optimal algorithm that combines the Karush–Kuhn–Tucker conditions with the branch-and-bound method to solve this problem. Finally, we evaluate our system in a simulation environment, and the results show that the system performs better than the baseline. (shrink)

We report a magnetization, magnetostriction, electrical resistivity, specific heat and neutron scattering study of a UNi 2/3 Rh 1/3 Al single crystal, a solid solution of an antiferromagnet UNiAl and a ferromagnet URhAl. The huge uniaxial magnetic anisotropy confining the principal magnetic response to the c axis in the parent compounds persists also for the solid solution. The magnetization curve at 1.6 K has a pronounced S shape with an inflection at 12 T. The temperature dependence of magnetic susceptibility (...) exhibits a maximum around 10 K and is magnetic history dependent at lower temperatures where the resistivity increases linearly with decreasing temperature. The low-temperature „ anomaly is removed in a magnetic field applied along c , which yields a large negative magnetoresistance amounting to m 46 z in 14 T . The C/T values exhibit a minimum around 12 K and below 8 K they become nearly constant , which is strongly affected by magnetic fields. Neutron scattering data confirm a non-magnetic ground state of UNi 2/3 Rh 1/3 Al. The bulk properties at low temperatures are tentatively attributed to the freezing of U magnetic moments with antiferromagnetic correlations. The additional intensities detected on top of nuclear reflections in neutron diffraction in a magnetic field applied along c are found to be proportional to the field-induced magnetization, which reflects field-induced ferromagnetic coupling of U magnetic moments. This scenario is corroborated also by finding low-temperature magnetostriction data that also scale with the square of magnetization. (shrink)

Cities and towns are expanding and thriving as a result of urbanization, which also significantly changes the local climate. One of the most significant phenomena associated with urbanization is the Urban Heat Island (UHI) effect. This phenomenon is increasingly being studied worldwide. The paper aims to investigate the UHI phenomenon in the metropolitan area of Tirana, Albania. It analyses the impact of the UHI on four specific locations in Tirana, its causes and mitigation measures, as well as variations in (...) surface temperature, CO2 emissions, and relative humidity. The regions are measured and observed using a specific instrument such as the Testo 435. Considering the mean surface temperature variations between urban and rural regions ranging from 28.4°C to 33.7 °C, CO2 emissions from 302.9 ppm to 416.2 ppm, and relative humidity from 34.1% to 41.2%, it is found that the UHI impact in Tirana is significant. The lack of green spaces, high building density, urban patterns, building materials used, transport, and energy use are the main contributors to the UHI in central Tirana. Increasing green spaces, using reflective materials, and promoting sustainable urban design are some of the mitigation techniques suggested to reduce the UHI effect in Tirana. (shrink)

Climate has a strong influence on urban planning and also plays a fundamental role in soil composition affecting the character of plants and animals. The climate is a combination of different meteorological factors that characterized a specific region over a specific time. The movement of the Sun and Earth inclination toward it is the most important factors which determine the characteristics of the climate. The global movement of the air from equator toward poles and vice versa influences also drastically the (...) climate change. In this section are also included breezes. Also air relative humidity plays an important role shaping the climate. It plays a very important role in cloud formation. The built environment can influence the urban climate of the city through height, form, and applied building materials. Building form and shape, building materials, openings in the façade, and their orientation often are determined by climate parameters. Urban density, directions, and street network and their shape are related to the climate change, apart from topography. Density of urban structures produces important effects on the microclimatic conditions in external spaces. The bioclimatic behavior of each type of outdoor spaces depends on the relationship with its surrounding elements. The city of Tirana is included in Mediterranean climate characterized by hot dry summers and mild cold wet winters with high daily thermal excursions. All of the countries bordering the Mediterranean Sea benefit from the Mediterranean climate. Specifically spotted, Tirana is part of Mediterranean coastal zone (<22 °C in temperature) with an annual temperature of 15.3 °C. In the inner city can be found areas with high pollution, which normally contain a high percentage of business and industry, settlements, and traffic, so-called “sealed” areas. They constitute “hyperthermic areas” or “heat islands”. The term “heat island” describes built-up areas which are hotter than nearby rural areas. Heat islands can affect communities by increasing summertime peak energy demand, air-conditioning costs, air pollution, greenhouse gas emissions, heat-related illness and mortality, and water quality. The aim of the bioclimatic design is also the reduction of the heat-island phenomenon. The use of materials with different energy absorption capabilities and integration of green spaces into urban life is important. The vegetation effects on microclimate and in the built environment are present. Trees are necessary and indispensable to human life. They provide shelter for us, provide food, and their fibers cloth us. Implementation of the green belts in the city is one of the strategies in order to reduce heat-island effect. Vegetation also can provide a deep feeling of attachment to certain places and trees which are part of it. The use of trees avoids monotony and ensures diversification. They play a crucial role creating microclimates which influence the thermal comfort of people reducing heating or cooling loads. Vegetation also creates cooler microclimates around the building through evapotranspiration, reduces wind speed, regulates humidity, and reduces temperature. It is observed that tree species have a greater influence on humidity than on temperature. Trees can also absorb and reduce the reverberation time of the sound, behaving as sound buffers. The benefits of tree plantation in the inner city are enormous and they can’t be neglected. (shrink)

An attempt is made to clarify a thought experiment introduced by P. T. Landsberg concerning the relativistic heat flow between bodies in relative motion. It is shown that if the problem is analyzed within the covariant thermodynamics developed by R. Balescu, supplemented by the second law of thermodynamics as proposed here, then such heat flow considerations do not fix the transformation of temperature as Landsberg contends. Instead, the transformation of temperature is left as being purely a matter of (...) definition. (shrink)

Philosophical discussions regarding the status of emotion as a scientific domain usually get framed in terms of the question whether emotion is a natural kind. That approach to the issues is wrongheaded for two reasons. First, it has led to an intractable philosophical impasse that ultimately misconstrues the character of the relevant debate in emotion science. Second, and most important, it entirely ignores valence, a central feature of emotion experience, and probably the most promising criterion for demarcating emotion from cognition (...) and other related domains. An alternate philosophical hypothesis for addressing the issues is pro- posed. It is that emotion is a naturally occurring valenced phenomenon that is.. (shrink)

Can managers detect honest people’s lies in a handwritten message? In this article, I will briefly discuss graphology and a basic model of interpersonal communication. I will then develop a fundamental theoretical framework of eight principles for detecting lies based on the basic communication model, handwriting analyses, and the following assumptions: For most people, it is easier to tell the truth than to tell lies. This applies to handwritings also. When most honest people lie, they try to hide their stressful (...) emotions in the encoding process. As a consequence, they deviate from their own normal writing and violate their own personal moral standards. Interestingly enough, the art or science of detecting a lie in a handwritten sample is to focus not on what they write, but on how they write it. These 24 exhibits (cases) written in 11 languages—used in different parts of the world—help managers apply this important theoretical framework of interpersonal communication, understand the encoding process, pinpoint these sudden emotional changes, decode handwritten messages, unlock the secrets, reveal the message’s true meanings, and detect people’s lies.

In recent years, calls have been made to address the relative dearth of qualitative sociological investigation into the sensory dimensions of embodiment, including within physical cultures. This article contributes to a small, innovative and developing literature utilizing sociological phenomenology to examine sensuous embodiment. Drawing upon data from three research projects, here we explore some of the ‘sensuousities’ of ‘intense embodiment’ experiences as a distance-running-woman and a boxing-woman, respectively. Our analysis addresses the relatively unexplored haptic senses, particularly the ‘touch’ of (...) class='Hi'>heat. Heat has been argued to constitute a specific sensory mode, a trans-boundary sense. Our findings suggest that ‘lived’ heat, in our own physical-cultural experiences, has highly proprioceptive elements and is experienced as both a form of touch and as a distinct perceptual mode, dependent upon context. Our analysis coheres around two key themes that emerged as salient: (1) warming up, and (2) thermoregulation, which in lived experience were encountered as strongly interwoven. (shrink)

Our experiences of heat and cold are usually thought to represent states of things: their hotness and coldness. I propose a novel account according to which their contents are not states of things but processes, more specifically, the opposite processes of thermal energy being transmitted to and from the body, respectively. I call this account the Heat Exchange Model of heat perception. Having set out the evidence in support of the proposal, I conclude by showing how it (...) provides a new perspective on some old problems. (shrink)

For countless citizens in the United States, guns are objects of personal attachment that provide strong feelings of power and security. I argue that a key reason for such tight affective bonds is that, under certain conditions, guns become integrated into their owners’ embodied experience. To flesh out this view, I explain (a) how firearms, as material artifacts, can become a part of the feeling body and (b) how this integration impacts one’s experience of self, others, and the world. I (...) first apply the distinction between body-incorporation and body-extension by De Preester and Tsakiris (Phenomenol Cogn Sci 8:307–319, 2009) to delineate how guns can (and cannot) be integrated into lived bodies. I then introduce Ihde's (Technology and the life world: from garden to earth, Indiana University Press, Bloomington, 1990) notion of embodiment relations to elaborate on the key experiential features of technologically extended bodies and complement the previous, sensorimotor-centric accounts of bodily extension with Colombetti's (Phenomenology for the twenty-first century, Palgrave Macmillan, London, 2016) concept of affective incorporation. With this theoretical framework in place, I proceed to examine the motives and affective dynamics involved in the incorporation of guns, the practices by which this incorporation is constituted, and its impact on gun carriers’ habitual comportment. In doing so, I identify two notable contradictions: first, between a desire for the power afforded by firearms and the lack in oneself that this power implies, and second, between one’s seemingly beneficial feelings of confidence/safety and potentially harmful transformations in one’s perceptions of threat. To conclude, I discuss how my analysis challenges current theorization on technologically extended bodies and consider its relevance for ongoing debates over gun policy. (shrink)

ABSTRACT This article contrasts Francis Bacon’s understanding of civil war, sedition, and rebellion with that of his near contemporaries and predecessors, especially Montaigne, Bodin, Machiavelli, Alberico Gentili and Edward Forset. The article contends that for Bacon, civil war, sedition, and rebellion are the antitheses of good government and that which prudent policy aims to avoid. The article further argues that for Bacon as sedition and its extremities are caused by poverty and discontentment, and these, in Bacon’s view, are the result (...) of overpopulation or ‘surcharge of people’, Bacon’s view for the avoidance of civil war aims at policies of outward expansion in the form of colonies and wars of aggression, both of which aim to reduce the metropole’s own population and therewith its propensity to civil war. The article argues that a consideration of Bacon on civil war in particular will shed considerable light on the ideological origins of the British Empire which have often been ignored – where some contemporary political theorists and historians are keen to link ideologies of empire to corresponding positions in political anthropology. A consideration of Bacon’s thought on civil war will show, instead, the article contends, that for key ideological originators of imperial justifications, imperial projects have their origin in domestic politics and the avoidance of civil war.

Fossil organisms offer our only direct insight into how the distinctive body plans of extant organisms were assembled. However, realizing the potential evolutionary significance of fossils can be hampered by controversy over their interpretation. Here, as a guide to evaluating palaeontological debates, we outline the process and pitfalls of fossil interpretation. The physical remains of controversial fossils should be reconstructed before interpreting homologies, and choice of interpretative model should be explicit and justified. Extinct taxa lack characters diagnostic of extant clades (...) because the characters had not yet evolved, because of secondary loss, or because they have rotted away. The latter, if not taken into account, will lead to the spurious assignment of fossils to basally branching clades. Conflicting interpretations of fossils can often be resolved by considering all the steps in the process of anatomical analysis and phylogenetic placement, although we must accept that some fossil organisms are simply too incompletely preserved for their evolutionary significance to be realized.

DNA glycosylases remove aberrant DNA nucleobases as the first enzymatic step of the base excision repair (BER) pathway. The alkyl‐DNA glycosylases AlkC and AlkD adopt a unique structure based on α‐helical HEAT repeats. Both enzymes identify and excise their substrates without a base‐flipping mechanism used by other glycosylases and nucleic acid processing proteins to access nucleobases that are otherwise stacked inside the double‐helix. Consequently, these glycosylases act on a variety of cationic nucleobase modifications, including bulky adducts, not previously associated (...) with BER. The related non‐enzymatic HEAT‐like repeat (HLR) proteins, AlkD2, and AlkF, have unique nucleic acid binding properties that expand the functions of this relatively new protein superfamily beyond DNA repair. Here, we review the phylogeny, biochemistry, and structures of the HLR proteins, which have helped broaden our understanding of the mechanisms by which DNA glycosylases locate and excise chemically modified DNA nucleobases.

Five aspects of visual change detection are reviewed. The first concerns the concept of change itself, in particular the ways it differs from the related notions of motion and difference. The second involves the various methodological approaches that have been developed to study change detection; it is shown that under a variety of conditions observers are often unable to see large changes directly in their field of view. Next, it is argued that this “change blindness” indicates that focused (...) attention is needed to detect change, and that this can help map out the nature of visual attention. The fourth aspect concerns how these results affect our understanding of visual perception—for example, the implication that a sparse, dynamic representation underlies much of our visual experience. Finally, a brief discussion is presented concerning the limits to our current understanding of change detection. (shrink)

Detecting introspective errors about consciousness presents challenges that are widely supposed to be difficult, if not impossible, to overcome. This is a problem for consciousness science because many central questions turn on when and to what extent we should trust subjects’ introspective reports. This has led some authors to suggest that we should abandon introspection as a source of evidence when constructing a science of consciousness. Others have concluded that central questions in consciousness science cannot be answered via empirical investigation. (...) I argue that on closer inspection, the challenges associated with detecting introspective errors can be overcome. I demonstrate how natural kind reasoning—the iterative application of inference to the best explanation to home in on and leverage regularities in nature—can allow us to detect introspective errors even in difficult cases such as judgments about mental imagery, and I conclude that worries about intractable methodological challenges in consciousness science are misguided.

The aim of this paper is to raise two questions. The first question is: How is pessimism related to Buddhism (and vice versa)? The second question is: What relation does an immanent philosophy have to pessimism and Buddhism, if any? Using True Detective, an American television crime drama, as my point of departure, first I will outline some of the likenesses between Buddhism and pessimism. At the same time, I will show how the conduct of one of the main characters (...) in True Detective resembles the paths of Buddhism and pessimism, even though he is ethical in a strictly non-pessimistic and non-Buddhist fashion. Last, I will try to place these findings in perspective through the French philosopher Gilles Deleuze’s thoughts. Hereby, I hope to illustrate that joy, not suffering, is basic to human existence, and how human beings may overcome a spiritual pessimism. (shrink)

Investigating the trail of philosophical leads in HBO’s chilling True Detective series, an elite team of philosophers examine far-reaching riddles including human pessimism, Rust’s anti-natalism, the problem of evil, and the ‘flat circle’.

Research on thermal “black-body” radiation played an essential role in the origin of the quantum theory at the beginning of the twentieth century. This is a well-known fact, but historians of science up to now have not generally recognized that studies of radiant heat were also important in an earlier episode in the development of modern physics: the transition from caloric theory to thermodynamics. During the period 1830–50, many physicists were led by these studies to accept a “wave theory (...) of heat”, although this theory subsequently faded into obscurity. (shrink)

xi should hope for "first and foremost" from any historical investigation, including his own, was that "it may not be too tedious. " II That hope is generally realized in Mach's historical writings, most of which are as lively and interesting now as they were when they appeared. Mach did not follow any existing model of historical or philosophical or scientific exposition, but went at things his own way combining the various approaches as needed to reach the goals he set (...) for himself. When he is at his best we get a sense of the Mach whom William James met on a visit to Prague, the Mach whose four hours of "unforgettable conversation" gave the forty year old, well traveled James the strongest "impression of pure intellectual genius" he had yet received, and whose "absolute simplicity of manner and winningness of smile" captivated him completely. 12 Consider, for example, the first few chapters of this book, Principles of the Theory of Heat, which Mach devotes to the notion of temperature, that most fundamental of all thermal concepts. He begins by trying to trace the path that leads from our sensations of hot and cold to a numerical temperature scale. (shrink)

Historical case studies of scientific concepts are a useful medium for showing how scientific ideas originate and how they change over time. They are thus a useful tool for conveying knowledge about the nature of science. This paper focuses on the concepts of heat and temperature and discusses some issues related to choosing the content for a historical case study which incorporates not only nature of science perspectives but understandings related to what we know about the teaching and learning (...) of these concepts. The case study is designed for first-year university chemistry students as an introduction to their study of thermodynamics. The paper includes a general chemistry textbook analysis of the heat and temperature concepts and a discussion of the caloric theory of heat, thermometry, and a brief survey of how the energy concept transformed our understanding of heat and temperature.

Our concern is in explaining how and why models give us useful knowledge. We argue that if we are to understand how models function in the actual scientific practice the representational approach to models proves either misleading or too minimal. We propose turning from the representational approach to the artefactual, which implies also a new unit of analysis: the activity of modelling. Modelling, we suggest, could be approached as a specific practice in which concrete artefacts, i.e., models, are constructed with (...) the help of specific representational means and used in various ways, for example, for the purposes of scientific reasoning, theory construction and design of experiments and other artefacts. Furthermore, in this activity of modelling the model construction is intertwined with the construction of new phenomena, theoretical principles and new scientific concepts. We will illustrate these claims by studying the construction of the ideal heat engine by Sadi Carnot. (shrink)

Detecting contract cheating in written submissions can be difficult beyond direct plagiarism detectable via technology. Successfully identifying potential cases of contract cheating in written work such as essays and reports is largely dependent on the experience of assessors and knowledge of student. It is further dependent on their familiarity with the patterns and clues evident in sections of body text and reference materials to identify irregularities. Consequently, some knowledge of what the patterns and clues look like is required. This paper (...) documents how to identify some of the patterns and clues observed in essay and report submissions. Effective assessment design with specific contextual requirements make irregularities easier to detect and interpret. The irregularities identified were confirmed as instances of contract cheating through conversations held with postgraduate students. An essential element of the conversations was the evidence presented for discussion. Irregularities were noted on a pro-forma specifically developed for this purpose. Patterns identified include misrepresented bibliographic data, inappropriate references, irrelevant material and generalised text that did not address the assessment question or grading criteria. The validated patterns formed the basis of identifying potential instances of contract cheating in later submissions. Timely conversations with students before the end of semester are essential to determining whether the patterns and clues link to poor knowledge of academic writing conventions or classified as contract cheating necessitating the application of appropriate penalties under institutional policies and procedures.

Threshold- and signal-detection-based models have dominated theorizing about recognition memory. Building upon these theoretical frameworks, we have argued for a dual-process model in which conscious recollection and familiarity contribute to memory performance. In the current paper we assessed several memory models by examining the effects of levels of processing and the number of presentations on recognition memory receiver operating characteristics . In general, when the ROCs were plotted in probability space they exhibited an inverted U shape; however, when they (...) were plotted inzspace they exhibited a U shape. An examination of the ROCs showed that the dual-process model could account for the observed ROCs, but that models based solely on either threshold or signal-detection processes failed to provide a sufficient account of the data. Furthermore, an examination of subjects' introspective reports using the remember/know procedure showed that subjects were aware of recollection and familiarity and were able to consistently report on their occurrence. The remember/know data were used to accurately predict the shapes of the ROCs, and estimates of recollection and familiarity derived from the ROC data mirrored the subjective reports of these processes.
