Are there illusions of duration? Certainly, many experiences of an event’s duration differ from its measure in clock duration, the measure of that event in seconds, minutes, hours, and so forth. However, I argue that an illusory duration requires more than difference from a real duration; it requires difference from a duration that is relevant to experience. It is plausible to hold that there are many kinds of real duration and reason to question the relevance of all of them. In (...) particular, the interpretation of experienced duration as illusory is typical because it is compared to clock time; the experience of duration goes wrong by being different from a clock measurement of duration. However, I argue that clock duration is not obviously relevant to evaluating the experience of duration.In response, one might hold that it is plausible to evaluate experience by clock duration because clocks more closely match reality than experiences do; on the scale of experience, clock time is no different to real duration. It is not that experienced duration is an illusion because it is merely different from clock duration; it is an illusion because it is different from real duration and we know this because of its difference from clock duration. It is like illusions of size: some object seems to be a size it is not and we know this by comparing it to an object we can otherwise accurately measure by meters.However, unlike size illusions, it is not clear what the ‘real duration’ is against which we should evaluate apparent duration. What is meant by ‘real duration’ involves either an appeal to the duration of substantial absolute time or some kind of duration in things, for example, duration which is the measure of change in some kind of process. is an irrelevant duration; few positions hold that we experience absolute time. As for, if real duration is a measure of change, then, for experienced duration to match clock duration, they must both agree on the relevant change. If there is a difference in what is treated as the real duration, then neither experience nor clocks can be treated as evaluable in terms of the other.Finally, we may have an illusory duration because there are cases of variation between experiences of the same duration. Yet, even here, we may be misled; we may not be directly comparing experiences. We compare the experienced durations through first measuring each in terms of clock duration. If there is a variability in the relationship between clock standard and some relevant standard for experience, then one expects anything accurately meeting one standard to differ from anything accurately meeting the other. The error is holding there is a stable relationship between the standards. This error is not a matter of our experience of duration, and so is not an illusion of duration. (shrink)

In order to manage the electricity consumption information of microgrid users, the reliability of electricity information collection is studied in this paper. The normal communication between the acquisition terminal and the smart meter is a key factor affecting the accurate collection of power information; it is the basis for ensuring the operation of the microgrid as well. In order to improve the reliability of the low power line communication between the acquisition terminal and smart meters, this article (...) first uses the static networking method to layer the smart meters and select relays from them and then select the optimal communication path based on integrating communication quality and relay forwarding number dynamically, which could avoid the signal conflict problem caused by simultaneous communication. Finally, by analyzing the influence of the time-varying power line channel on the smart meter communication, a method based on the integrated communication quality and the relay number to consider the time variability of low power line communication is proposed. Choosing the optimal path of the smart meters when the communication path is abnormal can not only establish a new communication path for communication in time, but also avoid communication failures caused by the time-varying channel. Through MATLAB simulation, the time-varying dynamic network of the power line channel is introduced in this paper, which improves the reliability of the smart meter communication and has certain guiding significance for the actual smart meter network construction in microgrid.

Part II systematically develops a fully temporal theory of meter that engages a variety of interpretive possibilities open to the performer. Here analyses of music from the early 17th century to the mid-20th century demonstrate the explanatory power of the theory and address broader issues of musical rhythm. The concluding chapters open the theory to more general questions of musical experience and its theoretical representation.

Smart grids are designed to revolutionize the energy sector by creating a smarter, more efficient and reliable power supply network. The rise of smart grids is a response to the need for a more comprehensive and sophisticated energy system that caters to the needs of homes and businesses. Key features of smart grids include the integration of renewable energy sources, decentralized generation and advanced distribution networks. At the heart of smart grids is a sophisticated metering system, consisting of intelligent (...) electronic devices that measure energy consumption and enable two-way communication between the utility company and the consumer. The information exchanged via these devices is critical, as it includes sensitive data such as energy consumption patterns and billing information. With the rise of the Internet of Things (IoT) and Industry 4.0, the security of this information is of utmost importance. This paper delves into the security challenges faced by advanced metering infrastructure (AMI) and highlights the crucial role played by cryptography in ensuring the secure exchange of sensitive information. Cryptographic protocols such as encryption, authentication and digital signatures are essential components of a secure smart grid infrastructure. These protocols work together to ensure the confidentiality, integrity and authenticity of the information exchanged between the utility company and the consumer. (shrink)

IntroductionChildren with severe physical disabilities are denied their fundamental right to move, restricting their development, independence, and participation in life. Brain-computer interfaces (BCIs) could enable children with complex physical needs to access power mobility (PM) devices, which could help them move safely and independently. BCIs have been studied for PM control for adults but remain unexamined in children. In this study, we explored the feasibility of BCI-enabled PM control for children with severe physical disabilities, assessing BCI performance, standard PM (...) skills and tolerability of BCI.Materials and methodsPatient-oriented pilot trial. Eight children with quadriplegic cerebral palsy attended two sessions where they used a simple, commercial-grade BCI system to activate a PM trainer device. Performance was assessed through controlled activation trials (holding the PM device still or activating it upon verbal and visual cueing), and basic PM skills (driving time, number of activations, stopping) were assessed through distance trials. Setup and calibration times, headset tolerability, workload, and patient/caregiver experience were also evaluated.ResultsAll participants completed the study with favorable tolerability and no serious adverse events or technological challenges. Average control accuracy was 78.3 ± 12.1%, participants were more reliably able to activate (95.7 ± 11.3%) the device than hold still (62.1 ± 23.7%). Positive trends were observed between performance and prior BCI experience and age. Participants were able to drive the PM device continuously an average of 1.5 meters for 3.0 s. They were able to stop at a target 53.1 ± 23.3% of the time, with significant variability. Participants tolerated the headset well, experienced mild-to-moderate workload and setup/calibration times were found to be practical. Participants were proud of their performance and both participants and families were eager to participate in future power mobility sessions.DiscussionBCI-enabled PM access appears feasible in disabled children based on evaluations of performance, tolerability, workload, and setup/calibration. Performance was comparable to existing pediatric BCI literature and surpasses established cut-off thresholds (70%) of “effective” BCI use. Participants exhibited PM skills that would categorize them as “emerging operational learners.” Continued exploration of BCI-enabled PM for children with severe physical disabilities is justified.

Coordination of a power system with the phasor measurement devices in real time on the load and generation sides is carried out within the context of smart grid studies. Power systems equipped with information systems in a smart grid pace with external security threats. Developing a smart grid which can resist against cyber threats is considered indispensable for the uninterrupted operation. In this study, a two-way secure communication methodology underpinned by a chaos-based encryption algorithm for PMU devices is (...) proposed. The proposed system uses the IEEE-14 busbar system on which the optimum PMU placement has been installed. The proposed hyperchaotic system-based encryption method is applied as a new security methodology among PMU devices. The success of results is evaluated by the completeness of data exchange, durations, the complexity of encryption-decryption processes, and strength of cryptography using a microcomputer-based implementation. The results show that the proposed microcomputer-based encryption algorithms can be directly embedded as encryption hardware units into PMU and PDC devices which have very fast signal processing capabilities taking into considerations the acceptable delay time for power system protection and measuring applications and quality metering applications which is 2 ms and 10 ms, respectively. While proposed algorithms can be used in TCP or UDP over IP-based IEEE C37.118, IEC 61850, and IEC 61850-90-5 communication frameworks, they can also be embedded into electronic cards, smartcards, or smart tokens which are utilized for authentication among smart grid components.

The National Health Service (NHS) was the first healthcare system globally to declare ambitions to become net carbon zero. To achieve this, a shift away from metered-dose inhalers which contain powerful greenhouse gases is necessary. Many patients can use dry powder inhalers which do not contain greenhouse gases and are equally effective at managing respiratory disease. This paper discusses the ethical issues that arise as the NHS attempts to mitigate climate change. Two ethical issues that pose a barrier to moving (...) away from metered-dose inhalers are considered: patients who decline an inhaler with a smaller carbon footprint and increased cost. I argue that while a patient is not morally justified in refusing a more environmentally sustainable inhaler due to the expected harms, a doctor may still prescribe a metered-dose inhaler if they believe that switching without consent might undermine trust or substantially worsen the patient’s health. Turning to cost, I argue that the imperative to combat climate change means the NHS should accept small increased financial costs for lower carbon inhalers, even though this provides no additional direct benefit for the patient. I then go on to consider the implications of the preceding analysis for policy and practice. I argue for a policy that minimises the impact of inhalers on the climate by advocating for a principle of environmental prescribing and explore decision-making in practice. While the arguments here pertain primarily to inhalers, the discussion has broader implications for debates around healthcare’s responsibility to be environmentally sustainable. (shrink)

Futsal is a sport that presents alternation of high- and low-intensity moments, which lacks investigations regarding the effects of the organization of the training load on biomotor skills. In this sense, this study aims to verify the monitoring of the training load throughout the season and the behavior of biomotor skills in futsal athletes. Twelve futsal athletes from the adult category, who competed in the first division of the Paulista championship, participated in the study. Throughout the season, the internal training (...) load was calculated, through the relationship between volume and the rate of perceived exertion, monotony, and training strain. The training periods were divided into preparatory, competitive, and competitive II for a total of four moments of evaluation: M1: at the beginning of the preparatory period; M2: 50 week, at the end of the preparatory period; M3: 13th week, in the middle of the competitive period; and M4: at the start of the competitive period II. The tests used were: Power of lower limbs: countermovement jump ; Displacement speed, over the 10-meter distance, and Aerobic power by the Carminatti test. The variables analyzed were compared at different moments of evaluation using the two-way ANOVA completed by the Bonferroni test. For monotony, training strain, and ILT, the ANOVA ONE-WAY test was used between the evaluation periods completed by the Bonferroni test. The significance value adopted was p < 0.05. A significant improvement was observed in the power of lower limbs from M1 to M3, from M2 to M3, and from M1 to M4. Aerobic power showed a significant increase from M1 to M3 and from M1 to M4. The ITL showed a difference between competitive I and II in relation to the preparatory period. In conclusion, the proposed training organization was sufficient to improve the power of the lower limbs and the aerobic power. (shrink)

The first poems about the Prophet Muḥammad appeared while he was alive. These first examples, which are panegyrics (madīḥ, i‛tiẕār, fakhr and ris̱ā), largely reflect the characteristics of the pre-Islamic qaṣīda poetry. Due to the developments in the following centuries, the number of poems about the Prophet increased. And thus, a separate literary genre was formed under the name al-madīḥ al-nabawī. Especially the fact that sufi leaning poets contributed to the literary richness in this field. Another factor is the beginning (...) of the tradition of writing mawlid poems in memory of the birth of the Prophet Muḥammad. The thirteenth century was an important period for poems praising the Prophet Muḥammad. Two important poets emerged in this century. One of them is Egyptian poet al-Būṣīrī and the other is Baghdad's famous poet, Yaḥyā al-Ṣarṣarī. Even after his death, Ṣarṣarî’s works with high literary value were read and memorized in the circles of science, literature and Sufism. Due to his competence in the field, al-Ṣarṣarī was known as the poet of the Prophet and Ḥassān b. Thābit of his time. However, it is understood that his poems, which lost their importance in literary circles over time, were not studied as much as they deserved in the modern period. In this article, his life and works are introduced and basic language and stylistic features of his poems are examined. Also, the image of the Prophet in his poems was determined within the framework of the political conditions of the period.Summary: In the field of madīh nabawī, which first appeared in the ‘Asr al-Sa’āda and has continued to the present day, especially two names stand out in the 7th/13th century, when famous poets such as Macduddīn al-Vitrī (d. 662/1264), Ibn al-Muraḥḥal (d. 699/1300) and Ṣafiyyuddīn al-Ḥillī (d. 749/1348) were also raised. One of them is the Egyptian poet al-Būṣīrī (d. 695/1296), who left his mark on the field of madīh nabawī with his many poems, especially Qaṣīda Burda, and the other is the Iraqi poet Yahya al-Ṣarṣarī (d. 656/1258), who was named Shā‘iru Rasūlillāh (The poet of the Prophet) and Ḥassānu Vaḳtihī (Ḥassān of that period) because of the quality of his poems in this field.al-Ṣarṣarī, was born in the village of al-Ṣarṣar, near Baghdad, spent most of his life in the shadow of Baghdad’s political instability and the social collapse that developed in parallel. He was killed in 656/1258 by the Mongolian forces that invaded Baghdad. al-Ṣarṣarī was extremely knowledgeable in fiqh, hadith, language, and ‘ilm al-qirāa. Our poet adopted the views of the Hanbalī law school. In addition, he turned to Sufism and became a murīd (disciple) of Ali ibn Idrīs al-Ya‘kūbī, a student of Abdalqadīr al-Gīlanī who was accepted as the founder of Qādiriyya. He was closely attached to the Sunnah of the Prophet and was fond of reading the Quran. He was chaste and patient and was content with what he had himself. All his works are poetic and they all concern the madīh nabawī or fiqh.Since his poems, almost all of which are about the praise of the Prophet, have a high literary value, they were read, memorized and narrated for a long time in the circles of science, literature and Sufism. In terms of its structure, his poems are based on the traditional forms of Arab qasīda. In the introductory sections of his poems, he often expresses his longing for Madina. The main subject in poems is usually the Prophet and his superior features. In the last part, he usually says salāt for the Prophet and seeks help from him. It can be said that he used simple language in his poems. The vocabulary reflects the characteristics of the urban life in which he lived. The source of inspiration for his poems are the Qur’an and especially the hadith of the Prophet. He uses the potential of literary arts as much as possible while conveying his feelings. But he does not allow the correct information to be lost due to these arts on a serious subject such as depicting the Prophet. We can see a lot of badī‘ (creative) art in some of his poems. But we can immediately understand that these arts do not spoil the beauty of his expression. The poet provides rhythm and harmony in his poetry with the meter and rhyme in accordance with the classical Arabic qasida rules. In addition, he strengthens the musicality in poetry with puns (jinās) and repetition.The influence of the instability of the region where al-Ṣarṣarī lived on his poems is obvious. According to him, the main reason for the terrible situation that Muslims were in was that they were away from the way of the Prophet. He thought that it would be possible to go back to the old peaceful days by following the way of the Prophet. Perhaps as a result of this opinion, he allocated his qasīda to the narration of the Prophet and his Companions. In his poems, he describes the Prophet with his names, superior qualities, physical and moral characteristics. He says that the sentences describing the Prophet are the ornament of poems and believes that praising him is a mean of salvation in the next world. He also hoped that the poems he said in order to achieve spiritual ascension would protect himself against the troubled events of the period.In his poems, especially on the occasion of mawlīd, al-Ṣarṣarī mentions the Prophet’s physical characteristics and likens his smiling face to a bright full moon, his brows to the letter nûn, his teeth to pearls. He describes the Prophet as a man with black eyes, broad shoulders, born with kohl-lined eyes, and who emanates a beautiful scent as a requirement of his creation. The poet, who also touches on the Prophet’s powerful address, states that his speech is more effective than Luqman’s wise words by virtue of his jawami‘ al-kalim (comprehensive speech) and faṣl al-khiṭab (clear speech), and that his soft address, which states nothing other than the truth, is a blessing from Allah. He additionally describes the Prophet’s plain words, easy to understand by all, as more valuable than jewels. al-Ṣarṣarī, who praises the Prophet in terms of morality with basic human virtues such as bashfulness, justice, modesty, and courage, emphasizes that he is, a paragon of patience, perseverance, kindness, and compassion through analogies such as, “his clothes are peace and perseverance”, his “cover is kindness and forgiveness”. In his world of imagery, the Prophet’s benevolence is so abundant like the rain that the clouds cannot compete with him. Also, he does not shame anybody for what he gives. He bestows the most valuable possessions like gold and camels. Even the respectable personalities of the tribe benefit from his grace. He is so generous that he is giving even when the clouds are stingy about giving rain during times of drought. He welcomes with a smile those who approach him with requests. The donations he makes privately are entirely satisfying.The image of prophethood in al-Ṣarṣarī’s poems, is centralized around the thought of nūr Muhammadī (prophetic light) and the miracles of the Prophet. He reminds that the Prophet never gave up despite the calamities he encountered and that he was supported with extraordinary events in various stages of his life since he was born, and reflects the understanding that the prophet is spiritually supporting the community with his nūr, and in the case the community follow his sunnah, overcoming the Mongolian attacks, which seems like a miracle, is possible. The mention of Qattāl (warrior), Māḥī (eliminator of disbelief), Ẓāhir, Ẓāfir, Manṣūr and Muẓaffar (victorious) among the Prophet’s names, especially those that evoke the superiority he gained in his fight against the disbelievers, giving greater prominence to his courage and valor among his virtues are also related to the political and social conditions of the period. The couplets about the Companions of the Prophet following the couplets that describe the Prophet’s valor, the emphasis of their aid to the Prophet, and the particular mention of their fighter spirit may be considered in the same context. Perhaps, in this way, the poet aims to boost the courage of the Muslims who are exposed to Mongolian attacks with respect to protecting their spiritual and holy values against the enemy. (shrink)

He has used medical instruments, prosthetics, robotics, Virtual Reality systems, and the Internet to explore alternate, intimate, and involuntary interfaces with the body. He has performed with a THIRD HAND, a VIRTUAL ARM, a VIRTUAL BODY and a STOMACH SCULPTURE. He has acoustically and visually probed the body—having amplified brainwaves, blood-flow and muscle signals and filmed the inside of his lungs, stomach, and colon, approximately two meters of internal space. He has done twenty-five body SUSPENSIONS with insertions into the skin, in different positions and varying situations in private gallery spaces and in remote locations.For FRACTAL FLESH, as part of Telepolis in 1995, he developed a touch-screen interfaced Muscle Stimulation System, enabling remote access, actuation, and choreography of the body. Performances such as PING BODY and PARASITE (1996, 1997) probe notions of telematic scaling and the engineering of external, extended, and virtual nervous systems for the body using the Internet. In 1998 for Kampnagel, he completed EXOSKELETON—a pneumatically powered six-legged walking machine actuated by arm gestures. During 2000, he completed an EXTENDED ARM—a manipulator with eleven degrees-of-freedom that extends his arm to primate proportions and a MOTION PROSTHESIS—an intelligent, compliant servo-mechanism that enables the performance of precise, repetitive, and accelerated prompting or programming of the arms in real time.

Pindar’s songs were composed for men at play, but his poetry was political in its impulse and in its function. The men in question were rich and powerful, and their games were a display of exclusive class attributes, vicariously shared by lesser mortals who responded with gratitude and loyalty . Victories were counted as princely benefactions and laid up as city treasure like the wealth deposited in the treasuries at Delphi . Athletic victory was thus both a manifestation and an (...) enhancement of aristocratic domination, which meant that the poet who praised those who boxed and raced in pan-Hellenic games necessarily praised the social structure that depended on them.Pindar understood his political function and was proud of it—“I would consort with victors” .1 He believed in athletic contest as a model for all human life. He believed in the aristocratic system: “Inherited governance of cities lies properly with the nobility” . He believed also that praise poetry could regulate as well as laud that system, and he believed finally that such poetry was itself incorruptible. Games, song, and princely rulers were all parts of a single brilliant order, and this truth had a linguistic reflection, for the bit that tames a horse, the meter of a poetic line, and the moderation of a ruler were all called by the same name—metron. “Measure inheres in everything” . 1.

Although nanotechnology is often defined as operations on the 10-9 meters, the lack of charisma in the scale-bound definitions has been fortified by remarkable dreams and alluring promises that spark excitement for nanotechnology. The story of the rhetorical development of nanotechnology reveals how speculative claims are powerful constructions that create legitimacy in this emerging technological domain. From its inception, nanotechnology has been more of a dream than reality, more fiction than fact. In recent years, however, the term nanotechnology has been (...) actively drawn toward the present to begin to deliver on the fantastic expectations. This debate over time and timing is loaded with paradox. This work examines how future claims work to define what counts as nanotechnology and reveals dilemmas that accompany temporal disjunctures. Science and politics converge in debates about the future of technology as expectations serve to create and enforce power and legitimacy in the emerging area. (shrink)

BackgroundFunctional changes after spinal cord injury are related to changes in cortical plasticity. These changes can be measured with electroencephalography and has potential to be used as a clinical biomarker.MethodIn this longitudinal study participants underwent a total of 30 sessions of robotic-assisted gait training over a course of 6 weeks. The duration of each session was 30 min. Resting state EEG was recorded before and after 30-session rehabilitation therapy. To measure gait, we used the Walking Index for Spinal Cord Injury (...) Scale, 10-Meter- Walking Test, Timed-Up-and-Go, and 6-Min-Walking Test. Balance was measured using Berg Balance Scale.ResultsFifteen participants with incomplete SCI who had AIS C or D injuries based on American Spinal Cord Injury Association Impairment Scale classification were included in this study. Mean age was 35.7 years and the mean time since injury was 17.08 months. All participants showed clinical improvement with the rehabilitation program. EEG data revealed that high beta EEG activity in the central area had a negative correlation with gait and balance measured at baseline, in a way that greater high beta EEG power was related to worse clinical function at baseline. Moreover, improvement in gait and balance had negative correlations with the change in alpha/theta ratio in the parietal area.ConclusionIn SCI, functional impairment and subsequent improvement following rehabilitation therapy with RAGT correlated with the change in cortical activity measured by EEG. Our results suggest that EEG alpha/theta ratio may be a potential surrogate marker of functional improvement during rehabilitation. Future studies are necessary to improve and validate these findings as a neurophysiological biomarker for SCI rehabilitation. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Lesbian Desire in the Lyrics of SapphoSarah MaceJane McIntosh Snyder. Lesbian Desire in the Lyrics of Sappho. New York: Columbia University Press, 1997. xi 1 261 pp. Cloth, price not stated.Snyder’s aim in Lesbian Desire in the Lyrics of Sappho is to make Sappho’s poetry “come alive for the modern reader” (ix), which is to say, for the Greekless reader. To this end, the author bases her discussions (...) of Sappho’s poems on her own translations accompanied by transliterations of the Greek text. She also explains the system of inflection in Greek and Sappho’s lyric meters, discusses the meanings of Greek words, and lucidly summarizes some of the principal textual difficulties. The result is a far from unsophisticated introduction to Sappho’s poems and the complex issues of their interpretation. For the non-Greekless reader, Snyder reproduces Voigt’s text (with her own translations in parallel) in an appendix (163–218). Her notes (219–37) are scholarly but not pedantic and refer to most of the important recent and older scholarship on Sappho.Snyder’s translations of Sappho are good: quite literal, simple, and elegant. Although it is possible to take issue with a few renderings here and there, it would be caviling to cite examples here; I should note, however, that she has [End Page 636] a tendency to translate supplements (found, e.g., in Campbell) which do not appear in Voigt’s text, and has been somewhat inconsistent about bracketing supplements in her own translations (particularly, e.g., in 17 V). The transliterations would probably have served their purpose just as effectively if used only for illustrative purposes rather than throughout the text; presumably Greekless readers will not be able to connect sense and sound except where their attention is drawn to a particular phrase or verse. The first appendix, “A Guide to the Transliteration,” could have been improved by a pronunciation guide; nowhere does the author note distinctions between long and short alpha, iota, and upsilon.Snyder’s approach to interpreting Sappho’s lyrics is twofold. The author points out that her method “is inevitably that of the classical philologist” and that she is “heavily influenced by the assumptions of New Criticism and the tradition of close textual analysis” (ix). She intentionally steers clear of the subject of Sappho’s historical and social context (1), believing that “Sappho’s text—even in its battered state—has the power to stand alone, with the benefit of very little ancient social context to help explain the author’s purpose or intention” (79). At the same time Snyder identifies herself as a “feminist scholar” whose approach has been “significantly colored by the questions raised through the influence of women’s studies, gay and lesbian studies, and postmodernism” (ix). Thus she wishes “to read what is left of [Sappho’s] songs for what they can say to women (and men who are willing to abandon a masculinist frame of reference) who hear her words today” (1).Chapter 1, “Sappho and Aphrodite,” focuses on the Hymn to Aphrodite (1 V). After a close reading of the poem, with attention to Sappho’s themes and techniques of composition, Snyder advances the view that it “subverts the traditional system of female subordination by creating a female authorial self that is of key importance in this song” (16); the powerful goddess featured here also contrasts with “the helpless, girlish whiner of the Iliad” (10). She concludes that the poem “offers us a clear paradigm for a woman-centered perspective on the universe, one in which the goddess and the relationships between women take center stage” (24). This movement from close, text-based readings to more general assertions sets the pattern for chapters 1–4. In a discussion of 2 V Snyder asserts that the temple and grove are “encoded as female space” (19) but does not demonstrate how the description differs substantively from other passages describing idyllic settings in archaic lyric (e.g., Ibycus 286 PMG). The chapter concludes with a summary treatment of other fragments involving Eros or Aphrodite.Chapter 2, “The Construction of Desire,” focuses on 31 V. Properly dismissing interpretations based on “the disease... (shrink)

A poetic study of a singular form of urban industrial art and its place in American culture. They lie underfoot, embellished and gleaming. They seal off and provide entry to an underground world of conduits, water mains, power lines, and sewers. They appear by the thousands in our cities, but very few people ever look at them or think about them as art. At once completely ordinary and totally unexpected, manhole covers present an infinite variety of design in the (...) commonplace as well as a record of defunct utility companies, forgotten business firms, and obsolete foundries. Manhole Covers documents this singular form of urban industrial art and its place in American culture. Mimi and Robert Melnick first revealed their obsession with street hardware twenty years ago in a remarkable little book called Manhole Covers of Los Angeles. Printed in a small format and a limited edition, it quickly went out of print and is now a scarce collector's item. But that was just an introduction to their larger project, which has come to fruition in this book of 200 photographs and an extended narrative documenting manhole covers throughout the United States and discussing the history of their use, manufacture, and function. A subject that at first seems straightforward and commonplace becomes redolent and poetic in the Melnicks' hands, for their hieroglyphic reading of manhole covers reveals a chapter of urban history that can only be recovered from the logos and markings of these early disks. There are square lids, convex lids, perforated lids. And the older ones wear an astonishingly diverse range of anything-but-blank faces expressed in raised crosses, waffle grids, cut-out diamonds, radial stars, floral patterns, and honeycomb treads. The diversity of design corresponds to an equally diverse typology of form and function, as indicated by their evocative labels: handholes, vents, coalholes, grates, lampholes, storm drains, steam covers, meter lids, traffic buttons.

This essay offers a new perspective on Darwin’s evolutionary theorizing on the human arts of music, poetry and rhetoric. It argues that Darwin’s theory of the human arts is primarily a theory of their effects on our emotions. Contrary to the topical understanding Darwin nowhere claimed that the music of homo sapiens sapiens used to be performed, let alone still is performed in the service of sexual success. He exclusively stipulated that some such evolutionary attractor might have shaped the vocal (...) arts of our «half-human ancestors». In the human music proper, by contrast, he sees this archaic function only persist as a cognitively vague, yet intensely felt «mental reversion to the emotions and thoughts of a long-past age», as widely unconscious and barely decodable memory traces. Read in Gouldian terms the evolved proto-human «musical arts» have thus been «exapted», i.e. lost their presumable biologically adaptive function of evolutionary origin, yet have survived this exaptation and ever since serve new communicative functions while retaining some of their archaic affective power. Moreover, the arts of rhetoric and poetry, by using the hypothetically older neural and vocal architecture of singing (with regards to linguistic prosody, meter, and cadences), coopt this «exapted» emotional power of music into the novel field of symbolic language. Darwin’s understanding of rhetoric and poetry is shown to entail not only explicit references, but also many implicit similarities both with Greek and Latin rhetoric and poetics and, more specifically, with Romanticist assumptions regarding the origin and function of poetry.

With the further acceleration of urbanization in China, the proportions of both urban residents’ energy consumption and energy-consuming terminal electricity are showing an increasing trend at the same time. In view of the dynamic and time-varying complex system characteristics of power system, it is of great significance to study the impact mechanism of urbanization residents’ electricity consumption on the realization of demand-side management and environmental protection. Based on the one-year follow-up survey data obtained from household meter reading, this (...) paper studies the impact mechanism of urban residents’ electricity consumption in different seasons and terminals by descriptive analysis and multiple linear regression model. The results show that, on the whole, electricity is a necessity for urban households and does not change significantly with changes in income. At the turn of summer and autumn and the turn of winter and spring, high-income families tend to use higher levels of energy in pursuit of comfort, while low- and middle-income families do not have luxury consumption. In different seasons, the influence mechanism of household electricity consumption at different terminals is different. (shrink)

Despite the ubiquity of bees in Dickinson’s work, most interpreters denigrate her nature poems. But following several recent scholars, I identify Nietzschean/Dionysian overtones in the bee poems and suggest the figure of bees/hive/queen illuminates as feminist key to her corpus. First, (a) the bee’s sting represents martyred death; (b) its gold, immortality; (c) its tongue, the “lesbian phallus”; (d) its wings, poetic power; (e) its buzz, poetic melody, and (f) its organism, a joyful Dionysian Susan (her sister-in-law and love (...) interest) to Emily’s flower. Second, the hive represents her individual poems (with slants/dashes as stingers, wings as hymn meter, honey as rhymes, variant words as exiled bees, and accompanying flowers their Darwinian coevolution with bees), constituting her writing persona as a multi-voiced self-swarm, as organized in the apiary of her letters and fascicles. And third, the queen represents her Western cultural and religious inheritance wherein bees are symbols of the soul, reincarnation, poetic-philosophical vocation, and a Nietzschean, trans-Dionysian naturalist ontology—symbolized by apiarian Artemis.

In recent years, a growing number of small-to-medium-enterprises are embracing wind turbine projects not only as part of their cost reduction strategy but also to actively play their part in the global fight against climate change. However, it would appear there are currently limited empirical studies carried out in this emerging industry. This case study analyses the cost effectiveness of one such wind turbine initiative by a company in the Republic of Ireland, who invested in a 300 kW embedded wind (...) turbine project at the end of 2013. The research methodology which is primarily a case study analysis included comparing historical electricity utility bills which allowed the 2013 quantity of electrical energy units imported, i.e. the year before the turbine was installed to be compared with the 2014 value, i.e. the year after the turbine was installed. Numerous site visits were undertaken over a four-year period, during which electric meter readings were recorded and stored. The findings of this piece of research indicate that the installation of the embedded wind turbine had minimal positive effect on the annual electricity costs for the company. Indeed the turbine appears to have significant negative effects such as a need for an increased maximum import capacity and also it appeared to contribute to a deteriorating utility power factor. While the aesthetic nature of the on-site turbine seemed to create a positive image of the company, it would appear that caution should be exercised when business owners select alternative energy providers who claim to be experts in the energy field but may have limited knowledge in this area of wind energy, which as of yet has minimal robust research into all aspects of its benefits/attributes.

A minor modification of the arguments of Press and Lightman leads to an estimate of the height of the tallest running, breathing organism on a habitable planet as the Bohr radius multiplied by the three-tenths power of the ratio of the electrical to gravitational forces between two protons (rather than the one-quarter power that Press got for the largest animal that would not break in falling over, after making an assumption of unreasonable brittleness). My new estimate gives a (...) height of about 3.6 meters rather than Press’s original estimate of about 2.6 cm. It also implies that the number of atoms in the tallest runner is very roughly of the order of the nine-tenths power of the ratio of the electrical to gravitational forces between two protons, which is about 3×1032.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Iambic Poetics in the Roman Empire by Tom HawkinsGideon NisbetTom Hawkins. Iambic Poetics in the Roman Empire. Cambridge: Cambridge University Press, 2014. xi + 334 pp. Cloth, $99.This stimulating and highly readable book explores the ancient afterlife of three famous literary bully-boys: Archilochus, Semonides, and Hipponax, the unholy Trinity of archaic Greek iambus. Tom Hawkins sets out to examine their reception, not among the classical and Hellenistic Greek (...) poets to whom they were living forebears (although the Callimachean intertext is a lively presence, e.g., 40–51, 146–49), or in the literary flourishing that they in turn inspired in late Republican and “golden” Augustan Rome, but amid authors of the Empire and Late Antiquity, extending into a recognizably Christian age. Only one of the six authors chosen (Babrius) adopts an iambic meter, and three—Dio, Lucian, and Julian—do not even compose verse (or not here). Hawkins’ choices are piquant. He has sought out the kinds of text that classicists generally skip: odd, minor works by the less reputable pagans, and by the type of early churchman we tend [End Page 180] gratefully to surrender to our colleagues in theology. Indeed, some are scarcely read at all (qua texts) but merely dipped into as a source of corroborating factoids, at least until now (142, on Gregory Nazianzen). Hawkins contends that an “iambic tradition” of sorts remains culturally alive and vital throughout these early centuries c.e.: a tradition not so much of metrical continuation or even necessarily of working closely with the archaic texts, but nevertheless retaining a definite sense of the constituent elements (e.g., animal-fable, a scruffy narrator) that, variously combined, let the reader or audience know they are in dialogue with an “iambic mode” (terms are defined in the introduction’s first footnote, 2).Authors and readerships of these centuries had at their command much more of the text of the archaic iambicists than is available to us moderns, provided they cared to read it and could understand what they read (28–29 suggests it was often otherwise). Today, Archilochus et al. are mere tattered ghosts, pieced together by editorial ingenuity out of citations and mentions, and latterly read in papyrus fragments gleaned from ancient rubbish heaps (the heroes of this scholarly epic of reconstruction include the late Professor Martin West, news of whose death came shortly before this review went to press). Some of the Imperial poets and prose authors studied by Hawkins envisage an ideal reader to whom archaic iambus is an open book, but the true constant is the ancient biographical tradition about Archilochus in particular (the stories told about the others are often recognizable knock-offs, but all three are names to conjure with; there are grounds for thinking that Archilochus had become literally proverbial for invective abuse even among non-readers, 27). Hawkins is very good at showing how these interwoven life-stories took on a life of their own and continued to grow in the telling (9), all the more so perhaps as actual familiarity with the texts waned. Over several centuries and numerous genres, the malleable myth of iambus—the slighted outsider, embracing abjection to shock a complacent Establishment and shame his nemeses—proved endlessly useful as a temporary vantage point when authors felt like taking a walk on the wild side.The iambic tradition tracked by Hawkins thus has “more to do with the sediment of cultural memory about iambic poets and their poetry than with historical realities, but once we get beyond a fascination with origins, such sediment becomes the only reality worth talking about” (8). In Hawkins’ readings of his chosen texts, this textual-biographical muck is fertile stuff. Iteration and generic migration turn the iambic life-story into a potent and versatile literary trope which usefully combines ironic distance (to be, or even make like Archilochus is an obvious non-starter in such a belated and grown-up age), and thus self-evident deniability, with the implicit threat that traces of iambus’ murderous power may yet remain. For Hawkins, the hint is if anything strengthened by repeated, name-checking recusationes that keep the iambic biopic in the... (shrink)

War and Nature is an important, cogent, and timely book about the double‐edged nature of technology. Edmund Russell, through meticulous research, establishes a key nexus between the increased use of chemicals in war and peace during several key decades of the twentieth century and the generalized backlash against technology and its unintended consequences that occurred beginning in the mid‐1960s. He clearly places pesticides, rodenticides, herbicides, and chemical warfare agents alongside atomic energy, electronics, massive water harnessing and diversion projects, and other (...) prime examples of America's romance with progress. Thus, he joins his work with a significant body of research examining the United States's headlong plunge to embrace technology, along with sometimes belated efforts to grapple with its effects.The idea of progress has always been a distinctive factor in American identity. However, the fascination with progress was perhaps never so intense, so unreserved, and so naive as in the fifty years from 1914 to the early 1960s. During these years, as Russell points out, the pace of change was accelerated by two world wars that spawned the growth of powerful government agencies as well as commercial companies whose new products benefited richly from government‐funded research. Wartime imperatives hastened development of “miracle chemicals” that preserved the health of American soldiers, as when DDT was widely employed in the Pacific theater of war to kill malaria‐bearing mosquitoes. The result was what President Dwight D. Eisenhower, as he left office, termed the “military‐industrial complex.”Russell uses well‐chosen examples from the archives of chemical manufacturers to illustrate how defense contractors supplying electronics, atomic expertise, and other forms of technological expertise useful in warfare softened their public images by touting beneficent peacetime applications of their products. “Better Living Through Chemistry” along with “Progress Is Our Most Important Product” and other slogans familiar to citizens of the 1950s appealed not just to America's love of convenience and gadgetry. They also appealed to a fundamental U.S. belief that “modern science” would solve age‐old problems, erase perennial blights, and free people to live on a higher plane than any previously experienced by humankind.However, because defoliants, flame‐throwers, poison gases, and other chemical weapons that aided the war effort almost always conjured up negative images in the public mind, manufacturers used analogies of “victory” in war to victory over man's environment to retain a reputable and lucrative place in peacetime society.Perhaps most striking are the parallels between chemicals and atomic energy during the 1940s, 1950s, and early 1960s in the United States. Both chemicals and atomic energy proved their awesome power in hastening victory in World War II, and both needed softer images after the war ended. The promises of disease‐free fields and enormously increased crop yields appealed to the American public, just as did the hope of electricity “too cheap to meter” and nuclear medicine that might cure cancers.When chemicals began to poison birds, fish, and other species recognized as valuable and desirable to man, when fields lost their productivity, and when illnesses arose in certain occupations that could be linked to chemical exposure, the downsides of progress became evident. America recoiled and reevaluated. Russell weaves congressional testimony together with advertisements, popular cartoons, and other ephemera to bring to life this uniquely American story. He compels the reader to ask striking questions about a nation maturing and itself asking complex questions about one of its most cherished ideals.The final irony of Russell's book may lie in the fact that it was written before the World Trade Center attack on 11 September 2001 but published just afterward, in the midst of America's anthrax episodes in the fall of the same year. The world focus on chemical and biological warfare should now provide a whole set of additional readers for this valuable book. (shrink)

The 2003 blackout in the northern and eastern U.S. and Canada which caused a $6 billion loss in economic revenue is one of many indicators that the current electrical grid is outdated. Not only must the grid become more reliable, it must also become more efficient, reduce its impact on the environment, incorporate alternative energy sources, allow for more consumer choices, and ensure cyber security. In effect, it must become smart. Significant investments in the billions of dollars are being made (...) to lay the infrastructure of the future Smart Grid. However, the authors argue that we must take great care not to sacrifice consumer privacy amidst an atmosphere of unbridled enthusiasm for electricity reform. Information proliferation, lax controls and insufficient oversight of this information could lead to unprecedented invasions of consumer privacy. Smart meters and smart appliances will constitute a data explosion of intimate details of daily life, and it is not yet clear who will have access to this information beyond a person’s utility provider. The authors of this paper urge the adoption of Dr. Ann Cavoukian’s conceptual model ‘SmartPrivacy’ to prevent potential invasions of privacy while ensuring full functionality of the Smart Grid. SmartPrivacy represents a broad arsenal of protections, encapsulating everything necessary to ensure that all of the personal information held by an organization is appropriately managed. These include: Privacy by Design; law, regulation and independent oversight; accountability and transparency; market forces, education and awareness; audit and control; data security; and fair information practices. Each of these elements is important, but the concept of Privacy by Design represents its sine qua non. When applying SmartPrivacy to the Smart Grid, not only will the grid be able to, for example, become increasingly resistant to attack and natural disasters—it will be able to do so while also becoming increasingly resistant to data leakage and breaches of personal information. The authors conclude that SmartPrivacy must be built into the Smart Grid during its current nascent stage, allowing for both consumer control of electricity consumption and consumer control of their personal information, which must go hand in hand. Doing so will ensure that consumer confidence and trust is gained, and that their participation in the Smart Grid contributes to the vision of creating a more efficient and environmentally friendly electrical grid, as well as one that is protective of privacy. This will result in a positive-sum outcome, where both environmental efficiency and privacy can coexist. (shrink)

For those who are eagerly awaiting the return of Christ in glory, the admonition articulated in Matthew 24:42 has always been of paramount importance. Not only are we counseled to remain ever vigilant, but the intellectual boundaries within which we may abide in our expectation are also carefully delineated, for it is here that Christ most firmly establishes his mandate that we profess a radical agnosticism regarding the time-tables of sacred history. Nonetheless, since the days of the Church Fathers there (...) have been some who, for a variety of reasons, have sought to arrive at a more certain — or at least more refined — understanding of the timing of the Parousia, most often through a combination of exegesis and numerology. To a certain degree, Christian of Stavelot's comments on Matthew 24:42 must be considered among these attempts. (shrink)

Tasked with the challenge to build better and better computers, quantum computing and classical computing face the same conundrum: the success of classical computing systems. Small quantum computing systems have been demonstrated, and intermediate-scale systems are on the horizon, capable of calculating numeric results or simulating physical systems far beyond what humans can do by hand. However, to be commercially viable, they must surpass what our wildly successful, highly advanced classical computers can already do. At the same time, those classical (...) computers continue to advance, but those advances are now constrained by thermodynamics, and will soon be limited by the discrete nature of atomic matter and ultimately quantum effects. Technological advances benefit both quantum and classical machinery, altering the competitive landscape. Can we build quantum computing systems that out-compute classical systems capable of some \(10^{30}\) logic gates per month? This article will discuss the interplay in these competing and cooperating technological trends. (shrink)
