Assessing the association between conceptual constructs are at the heart of quantitative research in educational and psychological research. Researchers apply different methods to the data to obtain results about the correlation between a set of variables. However, the question remains, how accurate are the results of the correlation obtained from these methods? Although various considerations should be taken to ensure accurate results, we focus on the types of analysis researchers apply to the data and discuss three methods most (...) researchers use to obtain results about correlation. Particularly, we show how correlation results in bivariate correlation, confirmatory factor analysis (CFA), and exploratory structural equation modeling (ESEM) differ substantially in size. We observe that methods that assume independence of the items often generate inflated factor correlations whereas methods that relax this assumption present uninflated, thus more accurate correlations. Because factor correlations are inflated in bivariate correlation and CFA, the discriminant validity of the constructs is often unattainable. In these methods, the size of the correlation can be very large and biased. We discuss the reasons for this variation and suggest the type of correlation that researchers should select and report.

This article presents a review of reverse correlation in neurophysiology. We discuss the basis of reverse correlation in linear transducers and in spiking neurons. The application of reverse correlation to measure the receptive fields of visual neurons using white noise and m‐sequences, and classical findings about spatial and color processing in the cortex resulting from such measurements, are emphasized. Finally, we describe new developments in reverse correlation, including “sub‐space” and categorical reverse‐correlation. Recent results obtained by (...) applying such methods in the orientation, spatial‐frequency and Fourier domains have revealed the importance of cortical inhibition in the establishment of sharp tuning selectivity in single neurons.

Based on the growing problem of heart diseases, their efficient diagnosis is of great importance to the modern world. Statistical inference is the tool that most physicians use for diagnosis, though in many cases it does not appear powerful enough. Clustering of patient instances allows finding out groups for which statistical models can be built more efficiently. However, the performance of such an approach depends on the features used as clustering attributes. In this paper, the methodology that consists of combining (...) unsupervised feature selection and grouping to improve the performance of statistical analysis is considered. We assume that the set of attributes used in clustering and statistical analysis phases should be different and not correlated. Thus, the method consisting of selecting reversed correlated features as attributes of cluster analysis is considered. The proposed methodology has been verified by experiments done on three real datasets of cardiovascular cases. The obtained effects have been evaluated regarding the number of detected dependencies between parameters. Experiment results showed the advantage of the presented approach compared to other feature selection methods and without using clustering to support statistical inference. (shrink)

Dynamic vision sensor is a kind of bioinspired sensor. It has the characteristics of fast response, large dynamic range, and asynchronous output event stream. These characteristics make it have advantages that traditional image sensors do not have in the field of tracking. The output form of the dynamic vision sensor is asynchronous event stream, and the object information needs to be provided by the relevant event cluster. This article proposes a method based on the event correlation index to (...) obtain the object’s position, contour, and other information and is compatible with traditional tracking methods. Experiments show that this method can obtain the position information of the moving object and its continuous motion trajectory and analyze the influence of the parameters on the tracking effect. This method will have broad application prospects in security, transportation, etc. (shrink)

Philosophers and scientists have maintained that causation, correlation, and partial correlation are essentially related. These views give rise to various rules of causal inference. This essay considers the claims of several philosophers and social scientists for causal systems with dichotomous variables. In section 2 important commonalities and differences are explicated among four major conceptions of correlation. In section 3 it is argued that whether correlation can serve as a measure of A's causal influence on B depends (...) upon the conception of causation being used and upon certain background assumptions. In section 4 five major kinds of partial correlation are explicated, and some of the important relations are established among two conceptions of partial correlation, the conception of screening off, the conception of partitioning, and the measures of causal influence which have been suggested by advocates of path analysis or structural equation methods. In section 5 it is argued that whether any of these five conceptions of partial correlation can serve as a measure of causal influence depends upon the conception of causation being used and upon certain background assumptions.The important conclusion is that each of the approaches (considered here) to causal inference for causal systems with dichotomous variables stands in need of important qualifications and revisions if they are to be justified.

argues that correlated interactions are necessary for group selection. His argument turns on a particular procedure for measuring the strength of selection, and employs a restricted conception of correlated interaction. It is here shown that the procedure in question is unreliable, and that while related procedures are reliable in special contexts, they do not require correlated interactions for group selection to occur. It is also shown that none of these procedures, all of which employ partial regression methods, are reliable when (...) correlated interactions of a specific kind arise, and it is argued that such correlated interactions will likely be ubiquitous in natural populations.

Changes in the methodology of the historical sciences make them more vulnerable to unjustifiable speculations being passed off as scientific results. The integrity of historical science is in peril due the way speculative and often unexamined causal assumptions are being used to generate data and underpin the identification of correlations in such data. A step toward a solution is to distinguish between plausible and speculative assumptions that facilitate the inference from measured and observed data to causal claims. One way to (...) do that is by comparing these assumptions against a well-attested set of aspects of causation, such as the so-called “Bradford Hill Criteria”. The BHC do not provide a test for causation or necessary and sufficient conditions for causation but do indicate grounds for further investigation. By revising the BHC to reflect the needs and focus of historical sciences, it will be possible to assess the cogency of methods of investigation. These will be the Historical Sciences Bradford Hill Criteria. An application to one area in historical science is used to demonstrate the effectiveness of the HSBHC, namely biogeography. Four methods are assessed in order to show how the HSBHC can be used to examine the assumptions between our data and the causal biogeographical processes we infer. (shrink)

Molecular interactions are at the origin of life. How molecules get at different locations in the cell and how they locate their partners is a major and partially unresolved question in biology that is paramount to signaling. Spatio‐temporal correlations of fluctuating fluorescently tagged molecules reveal how they move, interact, and bind in the different cellular compartments. Methods based on fluctuations represent a remarkable technical advancement in biological imaging. Here we discuss image analysis methods based on spatial and temporal correlation (...) of fluctuations, raster image correlation spectroscopy, number and brightness, and spatial cross‐correlations that give us information about how individual molecules move in cells and interact with partners at the single molecule level. These methods can be implemented with a standard laser scanning microscope and produce a cellular level spatio‐temporal map of molecular interactions. (shrink)

Teachers’ teaching psychological behavior and classroom development are the current research hotspots in the field of educational psychology. How to realize the data analysis of teachers’ teaching psychological behavior and classroom development is a problem that researchers urgently need to solve. Based on the theory of data correlation analysis, this paper uses modern Internet technology and big data analysis teacher teaching system to quantitatively and qualitatively analyze the potential of students, and build a corresponding model. Through rule correlation (...) technology, the article studies various internal correlations between teachers’ teaching psychological behavior, extracts valuable information from various daily data of students through big data analysis technology, and the WEB teacher’s teaching psychological behavior analysis system based on B/S structure solves the problem that the traditional model cannot measure. In the simulation process, the system is implemented by MVC three-tier architecture, the database uses MYSQL 5.0, the prediction questionnaire is formulated on the basis of the literature method and interviews, and the scale is compiled and tested after repeated revisions. Project analysis and factor analysis are performed on the data obtained from the table test to construct and screen indicators. The experimental results show that the teacher’s classroom teaching behavior index system adopted by the system is practical and feasible, including three first-level indicators, 10 s-level indicators, and 21 third-level indicators. The system has 87.1% completeness, which effectively improves teachers’ teaching psychology. (shrink)

Long-range correlation, a property of time series exhibiting long-term memory, is mainly studied in the statistical physics domain and has been reported to exist in natural language. Using a state-of-the-art method for such analysis, long-range correlation is first shown to occur in long CHILDES data sets. To understand why, Bayesian generative models of language, originally proposed in the cognitive scientific domain, are investigated. Among representative models, the Simon model was found to exhibit surprisingly good long-range correlation, (...) but {\em not} the Pitman-Yor model. Since the Simon model is known not to correctly reflect the vocabulary growth of natural language, a simple new model is devised as a conjunct of the Simon and Pitman-Yor models, such that long-range correlation holds with a correct vocabulary growth rate. The investigation overall suggests that uniform sampling is one cause of long-range correlation and could thus have a relation with actual linguistic processes. (shrink)

This article describes the aircraft image recognition system implemented using the phase correlation technique in Matlab environment. The phase correlation is computed by using the normalized cross-power spectrum between the database and the template test image. The main objective of this article is to develop methods for static analysis of aircraft images. An unknown fighter aircraft is recognized by comparing its static image with those from a database of images of aircraft. This work is a research initiative involving (...) the use of image processing techniques to detect three-dimensional aircraft object based on their 2D images, providing feedback information for strategic purposes. The phase correlation technique is found to give a better recognition result for the set of database and test images considered, compared with the invariant moments. The phase correlation method is also used in other areas such as image registration. Aircraft images used include those from AeroIndia 2011 held at Bangalore, India. (shrink)

Background: Rumination, a tendency to focus on negative self-related thoughts, is a central symptom of depression. Studying the self-related aspect of such symptoms is challenging because of the need to distinguish self effects from the emotional content of task stimuli. This study employed an emotionally neutral self-related paradigm to investigate possible altered self-processing in depression and its link to rumination. Methods: People with major depressive disorder (n = 25) and controls (n = 25) underwent task-based electro-encephalogram recording. We studied late (...) event-related potentials, along with low-frequency oscillatory power. We compared electroencephalogram metrics between groups and correlated them with depressive symptoms and reported rumination. Results: Participants with major depressive disorder displayed a difference in late positive potentials across frontocentral electrodes between self-related and non-self-related conditions. We found no such difference in controls. The magnitude of this difference was positively correlated with depressive symptoms and reported rumination. Participants with major depressive disorder also had elevated theta oscillation power at central electrodes in self-related conditions, a finding that we did not see in controls. Limitations: Patients with major depressive disorder were medicated at the time of the study. The group studied was primarily female, so the observed effects may have been sex-specific. Conclusion: Rumination appears to be linked to altered self-related processing in depression, independent of stimuli-related emotional confounds. This connection between self-related processing and depression may point to a self disorder as a core component of depression. (shrink)

Corresponding correlations is a method that allows us to infer formal causation from correlational data. In this paper, causal terms are traced to their philosophical and etymological roots. It is argued that causes are parts of their mutual whole . Nominalism, normal distributions and disjunctive causes are linked. Causal manifolds and sampling by potential are used to model conjunctive causes. Corresponding correlations are then demonstrated through simulations, in which causal relations are differentiated from spurious correlations. An algebraic method (...) for unraveling confounded variables is presented. Distinctions between laws and causes are made and related to corresponding correlations. The conclusion is that corresponding correlations should be a significant advance in causal inference. (shrink)

Upon previous research, the matrilineal system seems to oppose Islamic teaching. However, the matrilineal system practiced by the Minangkabau society in West Sumatra, Indonesia has its uniqueness. Thus, this study aims to examine the correlation between the Qur’an and gender roles within the context of Minangkabau customs, specifically focusing on the matrilineal aspect. The present study employs qualitative methods for conducting library research through critical analysis. This study discovered that the matrilineal system practiced by the Minangkabau society aligns with (...) Qur’anic teachings that respect the position of women in Islam. In the matrilineal system of Minangkabau, women hold significant strength and play an influential role in cultural and traditional practices. The Minangkabau tribe’s matrilineal system encompasses three key elements: marriage, inheritance and offspring. The marriage system is exogamous. Additionally, the practice of marriage is localised, with the husband typically residing in the wife’s household. Their inheritance is divided into pusako tinggi [from ancestors from generation to generation] and pusako randah (from the efforts of married couple). Women get pusako tinggi as they serve as protectors and a symbol of their community. In comparison, men take the responsibility of overseeing its preservation to prevent any form of misuse. Pusako randah is distributed as Islamic teaching. Lineage determination is primarily based on paternal lineage, aligning with Islamic teaching. Upon comprehensive analysis, it becomes evident that there is no conflict between the matrilineal system and Islamic teachings, particularly concerning principles of gender equality. Both women and men have significant roles, as the Qur’an provides extensive explanations regarding gender equality.Contribution: This research holds significant findings in establishing a great relation between Islamic teachings based on the Qur’an and the matrilineal principles practiced by the Minangkabau tribe.

Background. Sport training has an impact on other sciences. Among these sciences is physiology, in which emerged to form what is called sports physiology. The recent development in the science of physical education is one of the important factors in measuring and determining the nature of athletes' physical, physiological and biochemical adaptations and responses. The blood circulatory system is important as manifested in finding the relationship between some blood groups and the basic physical characteristics and the completion of the 100-meter (...) race. Objectives. The aim of this study is to identify the types of blood groups and their relationship to some physical traits, and the completion of the 100-meter race for some student athletes. Methods. the descriptive approach was used for its suitability to the research problem. The sample consisted of the students of second stage in the Department of Physical Education and Sports Sciences at Al-Mustaqbal University in Iraq. It was 143 students (35%) of the original research sample. With the a 143 sample size, the calculated confidence is 34.95 with standard deviation of ±3.87. Results. The study finds out a positive correlation between blood groups and some physical traits. There is also a positive correlation between blood groups and 100-meter sprint achievement as indicated from the statically data analysis and supported by the mean values 5.6 for O blood grouping. Conclusion. the blood group of athletes can take a role and impact on the speed and muscular strength tests. according to the results of this study the athletes who have AB and O blood group are more likely to win in 100 sprint races.

One of the positive arguments for the type-identity theory of mental states is an inference-to-the-best-explanation (IBE) argument, which purports to show that type-identity theory is likely true since it is the best explanation for the correlations between mental states and brain states that we find in the neurosciences. But given the methods of neuroscience, there are other relations besides identity that can explain such correlations. I illustrate some of these relations by examining the literature on the function of the hypothalamus (...) and its correlation with sensations of thirst. Given that there are relations besides identity that can explain such correlations, the type-identity theorist is left with a dilemma: either the correlations we consider are weak, in which case we do not have an IBE to an identity claim, or else the correlations we look at are maximally strong, in which case there are too few cases for the inductive part of the strategy to work.

Relationships between phonological and morphological complexity have long been proposed in the linguistic literature, with empirical investigations often seeking complexity trade-offs. Positive complexity correlations tend not to be viewed in terms of motivations. We argue that positive complexity correlations can be diachronically well-motivated, emerging from crosslinguistically prevalent processes of language change. We examine the correlation between syllable complexity and morphological synthesis, hypothesizing that the process of grammaticalization motivates a positive relationship between the two features. To test this, we conduct (...) a typological survey of 95 diverse languages and a corpus study of 21 languages with substantive (predominantly >10,000 words) corpora from the DoReCo project. The first study establishes a significant positive correlation between syllable complexity, measured in terms of maximal syllable patterns, and the index of synthesis (morpheme/word ratio). The second study tests the hypothesis that the relationship between syllable complexity and synthesis holds at local (word-initial and word-final) levels and within noun and verb types, as predicted by a grammaticalization account. While the findings of the corpus study are limited in their statistical power, the observed tendencies are consistent with our predictions. This study contributes important findings to the complexity literature, as well as a novel method which incorporates broad typological sampling and deep corpus analysis. (shrink)

The main aim of this paper is to analyze the electronic banking services in Kosovo’s banking net profit during the period 2013 - 2017. The paper discusses the role that these services have played in the development of the banking industry, modernization of e-commerce, and economic growth. These services provide higher security, faster and easier access by reducing transaction costs, access to more distant markets, and access to many products and services. The main paper results have shown that E-banking services (...) have the highest positive impact in banking net profit, while automated teller machine services have shown a slight positive impact. The highest positive correlation results have been seen in point-of-sale services, whereas automated teller machine services showed a negative correlation in banking net profit in Kosovo during the research period. The constant increase of demand for these services has enabled banks to increase their profits in the banking market of Kosovo. Therefore, the paper finds that commercial banks in Kosovo should increase their focus on the advancement and development of electronic banking services (particularly, E-Banking services which are very practical and can be easily used anywhere and anytime).

At the height of the COVID-19 pandemic, stringent lockdowns and sudden adjustments were enacted, both of which had a devastating effect on the economy of the Philippines and the method of education that was in place at the time. This resulted in shifts and serious challenges for everyone, particularly pupils from marginalized homes. Hence, this study employed a correlational design to determine if there is a significant relationship between academic burnout and academic procrastination among 150 grade 12 senior high (...) school students. The researchers used two instruments: Academic Procrastination Scale (APS) and Maslach Burnout Inventory (MBI) to measure the variables. Moreover, the statistical analysis reveals that the r coefficient of 0.80 indicates a high positive correlation between the variables. The p-value of 0.00, which is less than 0.05, leads to the decision to reject the null hypothesis. Hence, a significant relationship exists between procrastination and academic burnout among grade 12 senior high school students. (shrink)

Moral distress is a fundamental problem in the nursing profession that affects nurses. Critical care nurses are more susceptible to this problem due to the nature of their work. Moral distress may, in turn, lead to several undesirable consequences. This study aimed to determine the relationship between moral distress and intention to leave the ward among critical care nurses. This descriptive-correlational study was conducted by census method on all eligible nurses who worked in Coronary Care Unit (CCU) and Intensive (...) Care Unit (ICU) of AhVaz hospitals, Iran. Data was collected by Corley’s moral distress questionnaire and a researcher-made questionnaire to investigate the intention to leave the ward. Questionnaires were completed through self-report and data were analyzed using a t-test and Pearson correlation coefficient. The results showed that there was a direct association between moral distress and intension to leave the ward in critical care nurses (P < 0.05). Also, the intensity of moral distress (P = 0.03) and the intention to leave the ward (P = 0.007) were significantly higher in ICU nurses. Given the high exposure of critical care nurses with moral distress and its association with leaving the ward, it seems that devising strategies to reduce or control moral distress and its negative consequences are necessary, particularly in ICU nurses.

One of the challenging problems in large scale cyber-argumentation platforms is that users often engage and focus only on a few issues and leave other issues under-discussed and under-acknowledged. This kind of non-uniform participation obstructs the argumentation analysis models to retrieve collective intelligence from the underlying discussion. To resolve this problem, we developed an innovative opinion prediction model for a multi-issue cyber-argumentation environment. Our model predicts users’ opinions on the non-participated issues from similar users’ opinions on related issues using intelligent (...) argumentation techniques and a collaborative filtering method. Based on our detailed experimental results on an empirical dataset collected using our cyber-argumentation platform, our model is 21.7% more accurate, handles data sparsity better than other popular opinion prediction methods. Our model can also predict opinions on multiple issues simultaneously with reasonable accuracy. Contrary to existing opinion prediction models, which only predict whether a user agrees on an issue, our model predicts how much a user agrees on the issue. To our knowledge, this is the first research to attempt multi-issue opinion prediction with the partial agreement in the cyber-argumentation platform. With additional data on non-participated issues, our opinion prediction model can help the collective intelligence analysis models to analyze social phenomena more effectively and accurately in the cyber argumentation platform.

This is one of those cases to which Dr. 8 oodhouse's remark applies with all its force, that a method which leads to true results must have its logic — H.S Smith (" On Some of the Methods at Present in Use in Pure Geometry," p. 6) A goodly amount of modern metaphysics has concerned itself, in one form or another, with the question: what attitude should we take in regard to a language whose semantic underpinnings seem less than (...) certain? Since much of standard English is surely of this type, many philosophers have felt driven to extreme and unpalatable resolutions — wholesale rejection of attractive logical rules, radical "antirealism", "minimalism" about truth, and so forth, Scientists, however, have long dealt with analogous foundational insecurities and, under the duress of practicality, have framed a set of shifting attitudes towards language and reasoning that seem far more commonsensical than the extreme positions to which pure philosophy has often been led. Following this lead, this essay will recommend a more nuanced approach to linguistic insecurity that is neither naively optimistic nor mired in the gloomy sloughs of antirealism. (shrink)

We study the coupled dynamics of two populations of random replicators by means of statistical mechanics methods, and focus on the effects of relative population size, strategy correlations and heterogeneities in the respective cooperation pressures.

This technique allows one to formulate an effective dynamical theory, which is exact in the thermodynamic limit and which can be solved for persistent order parameters in a fixed-point regime regardless (...) of the symmetry of the interactions. The onset of instability can be determined self-consistently.

It is difficult for the conventional image compression method to achieve good compression effect in the underwater acoustic image, because the UWAI has large amount of noise and low correlation between pixel points. In this paper, fractal coding is introduced into UWAI compression, and a fractal coding algorithm based on interest region is proposed according to the importance of different regions in the image. The application problems of traditional quadtree segmentation in UWAIs was solved by the range block (...) segmentation method in the coding process which segmented the interest region into small size and the noninterest region into large size and balanced the compression ratio and the decoded image quality. This paper applies the classification, reduction codebook, and correlation coefficient matching strategy to narrow the search range of the range block in order to solve the problem of the long encoding time and the calculation amount of encoding process is greatly reduced. The experimental results show that the proposed algorithm improves the compression ratio and encoding speed while ensuring the image quality of important regions in the UWAI. (shrink)

The paper presents some knowledge of history of medicine – especially those from the embryological field – correlated with theological marks in order to motivate the rightfulness of the method of „bringing the mind down into the heart”, a procedure during the Jesus Prayer. The ascetic Fathers mentioned that the mind is an energy which starts from the heart and reaches the brain – which offers the possibility to express itself. It is possible to consider that this transfer begins (...) since the primitive heart is in the same plane and before the cerebral area. Then, after the folding of the embryo, the heart will be placed under the brain. So “bringing the mind down into the heart” is also biologically feasible. Although the primitive heart is structured after the neural tube, it starts beating at 21 to 22 days, unlike the brain which began its function on the 40th day. This explains the theological meaning of the heart, wider than the signification of the mind (attribute of the brain). (shrink)

The target article ignores the crucial role of correlational methods in the behavioral and social sciences.

I revisit Paul Tillich's theological methodology and contrast his practice of correlation with the syncretistic methodological practices of Pierre Teilhard de Chardin. I argue that the method of correlation, as referred to in Robert John Russell's 2001 Zygon article, fails to uphold Tillich's self‐limitation of his own methodology with regard to Tillich's insistence upon the theological circle. I assert that the theological circle, as taken from Tillich's Systematic Theology I, is a central facet within his methodology and (...) that this often‐ignored concept needs to be resuscitated if one is to remain authentically Tillichian in one's approach to the science‐and‐theology dialogue.

Background While it is generally acknowledged that self-prescribing among physicians poses some risk, research finds such behaviour to be common and in certain cases accepted by the medical community. Largely absent from the literature is knowledge about other activities doctors perform for their own medical care or for the informal treatment of family and friends. This study examined the variety, frequency and association of behaviours doctors report providing informally. Informal care included prescriptions, as well as any other type of personal (...) medical treatment (eg, monitoring chronic or serious conditions). Method A survey was sent to 2500 randomly-selected physicians in Colorado, 600 individuals returned questionnaires with usable data. The authors hypothesised: (1) physicians would prescribe the same types of treatment at home as they prescribed professionally; and (2) physicians who informally prescribed addictive medications would be more likely to engage in other types of informal medical care. Results Physicians who wrote prescriptions for antibiotics, psychotropics and opioids at work were more likely to prescribe these medications at home. Those prescribing addictive drugs outside of the office treated more serious illnesses in emergency situations, more chronic conditions and more major medical/surgical conditions informally than did those not routinely prescribing addictive medications. Physicians reported a variety of informal care behaviour and high frequency of informal care to family and friends. Discussion The frequency and variety of informal care reported in this study strongly argues for profession-wide discussion about ethical and guideline considerations for such behaviour. These areas are discussed in the paper. (shrink)

This research proposes and tests a new theoretical mechanism to account for a portion of the motherhood penalty in wages and related labor market outcomes. At least a portion of this penalty is attributable to discrimination based on the assumption that mothers are less competent and committed than other types of workers. But what happens when mothers definitively prove their competence and commitment? In this study, we examine whether mothers face discrimination in labor-market-type evaluations even when they provide indisputable evidence (...) that they are competent and committed to paid work. We test the hypothesis that evaluators discriminate against highly successful mothers by viewing them as less warm, less likable, and more interpersonally hostile than otherwise similar workers who are not mothers. The results support this “normative discrimination” hypothesis for female but not male evaluators. The findings have important implications for understanding the nature and persistence of discrimination toward mothers. (shrink)

Scientific research on consciousness is attempting to gather data about the relationship between consciousness and the physical world. The basic procedure is to measure consciousness through first-person reports, measure the physical world and look for correlations between these sets of measurements. While this work has focused on neural correlates of consciousness, it has also been proposed that information states in the brain might be linked to consciousness. This paper uses Floridi’s distinction between dedomena, data and information to state this claim (...) more precisely and suggests that the best starting point for this work is the potential correlation between data patterns and consciousness. Floridi’s method of levels of abstraction is used to understand how data can be measured at different levels of abstraction in the brain and the paper examines a number of problems with this work, which could make it difficult to prove that data patterns are correlated with consciousness.

The accumulation and advancement of gender scholarship over past decades has led us to the point where gender scholars today can leverage our deep understanding of the reproduction of gender inequality to develop and test models of change. In this lecture, I present one such model designed to reduce the negative effects of stereotypic biases on women’s workplace outcomes. After synthesizing the literature on stereotyping and bias and showing the limits of past change efforts, I develop a “small wins” model (...) of change. Key to this model is that researchers work with teams of managers to produce concrete, implementable actions that produce visible results. I argue that small wins motivate further action and are the building blocks to larger organizational transformation. Preliminary results from several case studies show that this approach can produce important changes in the short run, such as reducing gender biases in workplace evaluations, and that these small wins can inspire longer run change, such as increases in the rate of hiring women.

Two different types of subjective well-being (SWB) measures exhibit a remarkable difference in their correlations with people’s circumstances. The life satisfaction method shows relatively a strong correlation with income and material conveniences while affective measures are more tightly linked with freedom. Why is this so? To explain this difference I examine the cognitive mechanisms underlying these measures by means of dual process theory. This theory identifies two broad categories of cognition. One is Type 1: fast, intuitive, automatic and (...) autonomous. The other is Type 2: slow, deliberate and under conscious control. (They are also known as System 1 and System 2). I argue that in our normal decision making there is a division of labor between these mechanisms. Type 2 is more focused on making choices, comparing material goods and tradeoffs between them, while Type 1 is more oriented at the freedom that is necessary to make those choices. (shrink)

La Dogmatique de Gérard Siegwalt s’inspire profondément de la théologie de Paul Tillich, tout en demeurant pleinement originale. On le voit tout particulièrement à propos de la méthode de corrélation. Chez Siegwalt, la corrélation s’instaure entre deux types d’approche: l’approche sapientiale et l’approche prophétique . Dans cet article, j’entends montrer chez Siegwalt l’équivalence entre ces deux termes de la corrélation: la dimension transcendante du réel et le Dieu de la foi chrétienne.

On se demande dans cet article ce qu’est devenue la philosophie de la religion chez le Tillich américain, où il en est fort peu mention. On rappelle alors l’histoire de cette discipline. Elle devient indépendante de la théologie au cours des dix-huitième et dix-neuvième siècles, où elle finit par s’identifier à la «religion naturelle». Elle devient ainsi la cible des virulentes critiques de la théologie néo-orthodoxe inspirée par Karl Barth. Dans sa Théologie systématique, Tillich entend surmonter ce conflit par sa (...) «méthode de corrélation». Les deux grands problèmes de la philosophie de la religion sont par là pris en compte. Le problème plus théorique des catégories du religieux est repris dans la corrélation de la substance et de la forme , tandis que celui, plus existentiel, de la présence et de la perception de l’ultime est traité avec la corrélation de la question et de la réponse.

An analysis of the Delos capital makes it possible to outline a method of argumentation (based on the traces preserved on the surface of the eye) in favour of hypotheses about the methods of tracing the external and internal spirals. Based on these methods, an attempt has also been made to identify the Vitruvian indications. We have analysed the integration of the spiral in the composition of the whole facade of several Hellenistic Ionic capitals (from Halicarnassus, Priene, Magnesia on (...) the Meander, Didymes, Sardis and Delos) and a fortiori of the capital described by Vitruvius, having in view the width (D), the height of the volute (G), the height of the interior tangent of the volute (N) and the secondary diagonal (Ds). The constant, so to speak, utilisation was established of pentagons as important elements of the geometrical support in the architectural composition. Thus, the presence of a "common denominator" in the internal geometry of these capitals argues strongly in favour of a research procedure on the internal — geometrical — support of the composition of Ionic capitals.

Recent breakthroughs in artificial intelligence have primarily resulted from training deep neural networks (DNNs) with vast numbers of adjustable parameters on enormous datasets. Due to their complex internal structure, DNNs are frequently characterized as inscrutable ``black boxes,'' making it challenging to interpret the mechanisms underlying their impressive performance. This opacity creates difficulties for explanation, safety assurance, trustworthiness, and comparisons to human cognition, leading to divergent perspectives on these systems. This chapter examines recent developments in interpretability methods for DNNs, with a (...) focus on interventionist approaches inspired by causal explanation in philosophy of science. We argue that these methods offer a promising avenue for understanding how DNNs process information compared to merely behavioral benchmarking and correlational probing. We review key interventionist methods and illustrate their application through practical case studies. These methods allow researchers to identify and manipulate specific computational components within DNNs, providing insights into their causal structure and internal representations. We situate these approaches within the broader framework of causal abstraction, which aims to align low-level neural computations with high-level interpretable models. While acknowledging current limitations, we contend that interventionist methods offer a path towards more rigorous and theoretically grounded interpretability research, potentially informing both AI development and computational cognitive neuroscience.

Stereology is a valuable tool for neuroscientists, allowing them to obtain 3-Dimensional information from 2-Dimensional measurements made on appropriately sampled sections. This 3-D information is invaluable in correlating structural/functional relationships in the pursuit of far greater understanding of the function of the central nervous system. However, in carrying out such measurements, often based on limited data sets, there is a risk of experimenter bias. An important feature of modern design based stereology is to be aware of potential sources of bias (...) and eliminate them during the data collection. With many of the major neuroscience journals now insisting that quantitative data be presented, there is a greater need than ever for neuroscientists to understand the theory and practice behind quantitative methods, such as those offered by stereology. Quantitative Methods in Neuroscience is a cookbook of stereological methods written especially for neuroscientists. It provides clear and accessible advice about when and when not to use stereology. Throughout the book, the emphasis is on practical guidance, rather than discussions and formulae. Written by leading scientists in the field of stereology, with a Foreword by D.C. Sterio, the book will be a valuable introduction to these methods for neuroscientists, and all those involved in development of new drug programmes.Readership: Neuroscientists doing quantitative studies; Scientists involved in drug development; Pathologists.
