A motivational system approach to avoidance behavior is presented. According to this approach, a motivational state increases the probability of relevant response patterns and establishes the appropriate or “ideal” consummatory stimuli as positive reinforcers. In the case of feeding motivation, for example, hungry rats are likely to explore and gnaw, and to learn to persist in activities correlated with the reception of consummatory stimuli produced by ingestion of palatable substances. In the case of defense motivation, fearful rats are likely to (...) flee or freeze, and to learn to persist in activities correlated with consummatory stimuli produced by flight from a dangerous place. Defense system activation is distinct from alarm reactions. The latter prepare the animal for probable noxious events, involve relatively intense negative affect and extinguish rapidly in situations where the noxious event no longer occurs. In contrast, defense system activation potentiates innate and modified defense reactions, thus preparing the animal for possible, but not necessarily probable, noxious events; it involves little or no negative affect and extinguishes very slowly when the noxious event no longer occurs. With these assumptions and the resulting model we attempt to resolve several long-standing problems in avoidance learning, including the low correlation between negative affect and avoidance performance, differential rates of extinction for avoidance performance and conditioned emotional responses, and evidence that some avoidance responses are much more easily learned than others. In addition, the model has implications for the study of parallels between appetitive and aversive motivation, sign tracking in aversive conditioning, and orientation of flight responses. Historical antecedents and alternative approaches are discussed. (shrink)

Multitrait-multimethod (MTMM) analysis is one of the most frequently employed methods to examine the validity of psychological measures. Confirmatory factor analysis (CFA) is a commonly used analytic tool for examining MTMM data through the specification of trait and method latent variables. Most contemporary CFA-MTMM models either do not allow estimating correlations between the trait and method factors or they are restricted to linear trait-method relationships. There is no theoretical reason why trait and method relationships should always be linear, and quadratic (...) relationships are frequently proposed in the social sciences. In this article, we present two approaches for examining quadratic relations between traits and methods through extended latent difference and latent means CFA-MTMM models (Pohl et al., 2008; Pohl and Steyer, 2010). An application of the new approaches to a multi-rater study of the nine inattention symptoms of attention-deficit/hyperactivity disorder in children (N = 752) and the results of a Monte Carlo study to test the applicability of the models under a variety of data conditions are described.

A discussion is going on in cognitive science about the use of representations to explain how intelligent behavior is generated. In the traditional view, an organism is thought to incorporate representations. These provide an internal model that is used by the organism to instruct the motor apparatus so that the adaptive and anticipatory characteristics of behavior come about. So-called interactionists claim that this representational specification of behavior raises more problems than it solves. In their view, the notion of internal representational (...) models is to be dispensed with. Instead, behavior is to be explained as the intricate interaction between an embodied organism and the specific make up of an environment. The problem with a non-representational interactive account is that it has severe difficulties with anticipatory, future oriented behavior. The present paper extends the interactionist conceptual framework by drawing on ideas derived from the study of morphogenesis. This extended interactionist framework is based on an analysis of anticipatory behavior as a process which involves multiple spatio-temporal scales of neural, bodily and environmental dynamics. This extended conceptual framework provides the outlines for an explanation of anticipatory behavior without involving a representational specification of future goal states. (shrink)

The purpose of this paper is to explore the spiritually formative experiences of fifteen female seminary spouses who participated in a phenomenological research study. Graduate theological education is not limited to married, male students. Seminaries are diverse educational institutions that equip married and single students, as well as men and women from every country in the world for gospel ministry. Because of this broad population in theological education, the qualitative proposals in this essay are not generalizable to all schools, students, (...) and settings equally, but the perspectives of these seminary spouses are useful in cultivating a robustly holistic education for students who are married during their academic pursuits. It is the intent here to explore how theology can crossover from the academy to the home so that it is experienced in marriage. The goal then is to equip students, professors, and administrators to actively nurture the faith formation of the second-person of the ministry dyad. In order for these stakeholders to understand how to nurture this faith formation of the seminary spouse, we must first hear and understand the experiences of these wives as they share their reflections on these formational years as a part of their husband's education.

Cognitive science's basic premises are under attack. In particular, its focus on internal cognitive processes is a target. Intelligence is increasingly interpreted, not as a matter of reclusive thought, but as successful agent-environment interaction. The critics claim that a major reorientation of the field is necessary. However, this will only occur when there is a distinct alternative conceptual framework to replace the old one. Whether or not a serious alternative is provided is not clear. Among the critics there is some (...) consensus, however, that this role could be fulfilled by the concept of a 'behavioral system'. This integrates agent and environment into one encompassing general system. We will discuss two contexts in which the behavioral systems idea is being developed. Autonomous Agents Research is the enterprise of building behavior-based robots. Dynamical Systems Theory provides a mathematical framework well suited for describing the interactions between complex systems. We will conclude that both enterprises provide important contributions to the behavioral systems idea. But neither turns it into a full conceptual alternative which will initiate a major paradigm switch in cognitive science. The concept will need a lot of fleshing out before it can assume that role.

The purpose of this study is to examine F. S. C. Northrop's approach to Russian Communism via his analysis of the fundamental types of all possible concepts and how an exposition of the basic concepts of Russian Communism enable us to understand not only the past performances of the Soviet Union but also to predict what they are likely to do in the future. This goal is accomplished by an examination of three essays that Northrop penned over a period of (...) 14 years. Although a few critical remarks are tendered, my essay tends to be descriptive in an effort to introduce those unfamiliar with Northrop to the work of this vast mind. Readers of this journal will no doubt profit from exposure to Northrop's entire corpus. (shrink)

Borrett, Kelly and Kwan claim to provide neural-network models of important aspects of subjective human experience. To sidestep the long-standing and assumedly insurmountable problems with providing models of inner experience, they turn to a body-centered interpretation of experience, drawn from the work of Merleau-Ponty. This body-centered interpretation makes experience more tractable by linking it closely with bodily movement. However, when it comes to modeling, Borrett et al. ignore this body-centered interpretation and revert back to the traditional view of inner experience (...) as existing apart from the body. The result is uninteresting on two counts. The models that they present cannot be taken seriously as models of real inner experience. Additionally, these models do not apply to or extend the idea of a different, body-centered interpretation of experience either. (shrink)

Van Gelder presents the distinction between dynamical systems and digital computers as the core issue of current developments in cognitive science. We think this distinction is much less important than a reassessment of cognition as a neurally, bodily, and environmentally embedded process. Embedded cognition lines up naturally with dynamical models, but it would also stand if combined with classic computation.

COVID-19 has truly affected most of the world over the past many months, perhaps more than any other event in recent history. In the wake of this pandemic are patients, family members, and various types of care providers, all of whom share different levels of moral distress. Moral conflict occurs in disputes when individuals or groups have differences over, or are unable to translate to each other, deeply held beliefs, knowledge, and values. Such conflicts can seriously affect healthcare providers and (...) cause distress during disastrous situations such as pandemics when medical and human resources are stretched to the point of exhaustion. In the current pandemic, most hospitals and healthcare institutions in the United States have not allowed visitors to come to the hospitals to see their family or loved ones, even when the patient is dying. The moral conflict and moral distress among care providers when they see their patients dying alone can be unbearable and lead to ongoing grief and sadness. This paper will explore the concepts of moral distress and conflict among hospital staff and how a system-wide provider wellness programme can make a difference in healing and health. (shrink)

The current medical approach to erectile dysfunction (ED) consists of physiological, psychological and social components. This paper proposes an additional framework for thinking about ED based on phenomenology, by focusing on the theory of sexual projection. This framework will be complementary to the current medical approach to ED. Our phenomenological analysis of ED provides philosophical depth and illuminates overlooked aspects in the study of ED. Mainly by appealing to Merleau-Ponty’s Phenomenology of Perception, we suggest considering an additional etiology of ED (...) in terms of a weakening of a function of sexual projection. We argue that sexual projection can be problematized through cognitive interferences, changes in the ‘intentional arc’, and modifications in the subject’s ‘body schema’. Our approach further highlights the importance of considering the ‘existential situation’ of patients with ED. We close by reflecting briefly on some of the implications of this phenomenological framework for diagnosis and treatment of ED. (shrink)

This volume reaches beyond the controversy surrounding the teaching and learning of evolution in the United States, specifically in regard to the culture, politics, and beliefs found in the Southeast. The editors argue that despite a deep history of conflict in the region surrounding evolution, there is a wealth of evolution research taking place—from biodiversity in species to cultural evolution and human development. In fact, scientists, educators, and researchers from around the United States have found their niche in the South, (...) where biodiversity is high, culture runs deep, and the pace is just a little bit slower.

Emergence of the novel pathogenic coronavirus SARS‐CoV‐2 and its rapid pandemic spread presents challenges that demand immediate attention. Here, we describe the development of a semi‐quantitative high‐content microscopy‐based assay for detection of three major classes (IgG, IgA, and IgM) of SARS‐CoV‐2 specific antibodies in human samples. The possibility to detect antibodies against the entire viral proteome together with a robust semi‐automated image analysis workflow resulted in specific, sensitive and unbiased assay that complements the portfolio of SARS‐CoV‐2 serological assays. Sensitive, specific (...) and quantitative serological assays are urgently needed for a better understanding of humoral immune response against the virus as a basis for developing public health strategies to control viral spread. The procedure described here has been used for clinical studies and provides a general framework for the application of quantitative high‐throughput microscopy to rapidly develop serological assays for emerging virus infections.

The landscape of social theory has changed significantly over the three decades since the publication of Anthony Giddens and Jonathan Turner’s seminal Social Theory Today. Sociologists in the twenty-first century desperately need a new agenda centered around central questions of social theory. In Social Theory Now, Claudio E. Benzecry, Monika Krause, and Isaac Ariail Reed set a new course for sociologists, bringing together contributions from the most distinctive sociological traditions in an ambitious survey of where social theory is today (...) and where it might be going. The book provides a strategic window onto social theory based on current research, examining trends in classical traditions and the cutting edge of more recent approaches. From distinctive theoretical positions, contributors address questions about how social order is accomplished; the role of materiality, practice, and meaning; as well as the conditions for the knowledge of the social world. The theoretical traditions presented include cultural sociology, microsociologies, world-system theory and post-colonial theory, gender and feminism, actor network and network theory, systems theory, field theory, rational choice, poststructuralism, pragmatism, and the sociology of conventions. Each chapter introduces a tradition and presents an agenda for further theoretical development. Social Theory Now is an essential tool for sociologists. It will be central to the discussion and teaching of contemporary social theory for years to come. (shrink)

This paper considers characteristic views advanced in the past fifteen years that may be considered relatively sympathetic to student practices of cheating on graded assignments or exams. We detect and analyze typical fallacies that are recurrent in articles that promote a revisionist view of cheating as morally permissible. We offer a general, deontological argument that cheating is immoral. The efforts to justify student cheating take several forms. For example, it has been argued that cheating may be tolerated if the student (...) did not intend to cheat, perhaps because of a failure to understand the normal rules or expected procedures. We also argue that student collaboration in graded work constitutes cheating even if the instructor condones such collaboration. In a similar vein, we address the view that student copying is cheating even if the instructor alters the rules to allow such copying. This moral view can be applied to any cheating behavior, we argue. As a specific example, we demonstrate how it can be applied to the pedagogical recommendation that instructors should encourage their students to cheat in order to cultivate student skills in the area of cyber security. We also address the view that student cheating can be justified by situations in which the student believes that he/she is being subjected to an unfair or unethical overall learning environment.

In 2002, Luciano Floridi published a paper called What is the Philosophy of Information?, where he argues for a new paradigm in philosophical research. To what extent should his proposal be accepted? Is the Philosophy of Information actually a new paradigm, in the Kuhninan sense, in Philosophy? Or is it only a new branch of Epistemology? In our discussion we will argue in defense of Floridi’s proposal. We believe that Philosophy of Information has the types of features had by other (...) areas already acknowledge as authentic in Philosophy. By way of an analogical argument we will argue that since Philosophy of Information has its own topics, method and problems it would be counter-intuitive not to accept it as a new philosophical area. To strengthen our position we present and discuss main topics of Philosophy of Information. (shrink)

Abstract According to the Deprivation Approach, the evil of death is to be explained by the fact that death deprives us of the goods we would have enjoyed if we had lived longer. But the Deprivation Approach confronts a problem first discussed by Lucretius. Late birth seems to deprive us of the goods we would have enjoyed if we had been born earlier. Yet no one is troubled by late birth. So it’s hard to see why we should be troubled (...) by its temporal mirror image, early death. In a 1986 paper, Anthony Brueckner and John Martin Fischer appealed to a version of Derek Parfit’s “Bias toward the Future”; they claimed that early death deprives us of future goods that we care about, while late birth deprives us of past goods that we don’t care about. In this paper I show that the Brueckner–Fischer principle is open to several possible interpretations, but that it does not solve the Lucretius problem no matter how we understand it.

Figures of Thought looks at how mathematical works can be read as texts and examines their textual strategies. David Reed offers the first sustained and critical attempt to find a consistent argument or narrative thread in mathematical texts. Reed selects mathematicians from a range of historical periods and compares their approaches to organizing and arguing texts, using an extended commentary on Euclid's Elements as a central structuring framework. He develops fascinating interpretations of mathematicians' work throughout history, from Descartes (...) to Hilbert, Kronecker, Dedekind, Weil and Grothendieck. Reed traces the implications of this approach to the understanding of the history and development of mathematics. (shrink)

This work emerged from funded research examining collaboration among stake-holder organizations present at three U.S. nuclear weapons complex sites. The authors examine issues such as how and why stakeholder groups form collaborative alliances when dealing with the target organization, what leaders of stakeholder organizations actually think about when collaborating to deal with the target organization, and what outcomes result from the collaboration process. Drawing on stakeholder theory and research in interorganizational collaboration, the authors used an inductive, interview-based methodology to build (...) a model of collaboration among nonprofit stakeholder groups. The model contributes to the descriptive stream of stakeholder theory and, in turn, has implications for the instrumental stream. The model also offers implications for future researchers, leaders of stakeholder alliances, and leaders of target organizations. (shrink)

Biological evolution provides a creative fount of complex and subtle adaptations, often surprising the scientists who discover them. However, because evolution is an algorithmic process that transcends the substrate in which it occurs, evolution’s creativity is not limited to nature. Indeed, many researchers in the field of digital evolution have observed their evolving algorithms and organisms subverting their intentions, exposing unrecognized bugs in their code, producing unexpected adaptations, or exhibiting outcomes uncannily convergent with ones in nature. Such stories routinely reveal (...) creativity by evolution in these digital worlds, but they rarely fit into the standard scientific narrative. Instead they are often treated as mere obstacles to be overcome, rather than results that warrant study in their own right. The stories themselves are traded among researchers through oral tradition, but that mode of information transmission is inefficient and prone to error and outright loss. Moreover, the fact that these stories tend to be shared only among practitioners means that many natural scientists do not realize how interesting and lifelike digital organisms are and how natural their evolution can be. To our knowledge, no collection of such anecdotes has been published before. This paper is the crowd-sourced product of researchers in the fields of artificial life and evolutionary computation who have provided first-hand accounts of such cases. It thus serves as a written, fact-checked collection of scientifically important and even entertaining stories. In doing so we also present here substantial evidence that the existence and importance of evolutionary surprises extends beyond the natural world, and may indeed be a universal property of all complex evolving systems.

In their development of causal decision theory, Allan Gibbard and William Harper advocate a particular method for calculating the expected utility of an action, a method based upon the probabilities of certain counterfactuals. Gibbard and Harper then employ their method to support a two-box solution to Newcomb’s paradox. This paper argues against some of Gibbard and Harper’s key claims concerning the truth-values and probabilities of counterfactuals involved in expected utility calculations, thereby disputing their analysis of Newcomb’s Paradox. If we are (...) right, then Gibbard and Harper’s method of calculating expected utility does not adequately represent rational choice. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:HUME'S SCEPTICAL ARGUMENT AGAINST REASON In the section of the Treatise entitled Of scepticism with regard to reason Kume considers the mind as reflecting upon its own activities, monitors them as it were, and then adjusts them in accordance with certain principles and strategies. ^ What it discovers is that in drawing inferences, the mind sometimes errs. In the light of this knowledge, and in accordance with rational principles (...) of epistemic probabilities, it adjusts its response to any inference it makes from one of certainty to one with epistemic probability of a degree somewhat less than certainty. But this rational adjustment is itself the consequence of an inference, which will be subject to the same qualifications. By repeating this process, it seems that all certainty reduces to probability and all probability to zero. Hume's argument begins this way: Our reason must be consider 'd as a kind of cause, of which truth is the natural effect; but such-a-one as by _ the irruption of other causes, and by the inconstancy of our mental powers, may frequently be prevented. By this means all knowledge degenerates into probability ; and this probability is greater or less, according to our experience of the veracity or deceitfulness of our understanding, and according to the simplicity or intricacy of the question. 2 It is important to be clear on the logical structure of this argument. Consider an actual case of inference. This produces a state of belief or affirmation. Hume does not say that the inference does not produce truth, i.e., a true belief. But there is the possibility it does not. Nor is this a mere logical possibility. One can form the hypothesis about causes that this process of reasoning was in fact one which introduced an 91. element of error. One does not know that this hypothesis is true. But one does know that there is a certain probability that this causal hypothesis is true; as Hume puts it, it may frequently be true. Knowing that we have reasoned poorly sometimes (though not always) in the past, the hypothesis that we have on this occasion reasoned poorly has a certain probability, and we know this even though we have not verified the hypothesis for this particular occasion. On the basis of this unverified but nonetheless somewhat probable causal hypothesis we must as a matter of reason reduce the probability we attach to the belief or affirmation that was produced by the original inference. This reduction of probability is itself a matter of reasoning, however. Therefore about it, also, one can form the hypothesis that it is erroneous, and that the probability of the original affirmation was not reduced sufficiently. On the basis of this new hypothesis we must as a matter of reason reduce still further the probability of the first affirmation. And so on: as I reflect upon my use of reason, all the rules of logic require a continual diminution, and at last a total extinction of belief and evidence. (T183) The result here of the mind applying to its own activities what it discovers about itself is its ceasing to make any causal inferences. Feedback here yields the attitude of total scepticism, in the sense of rendering it reasonable that one ought totally to suspend judgment. To be sure, Hume does hold that no one is in fact such a total sceptic: Nature, by an absolute and uncontroulable necessity has determin 'd us to judge as well as to breathe and feel; nor can we any more forbear viewing certain objects in a stronger and fuller light, upon account of their customary connexion with a present impression, than we can hinder ourselves from thinking as long as we are awake, or see the 92. surrounding bodies, when we turn cur eyes towards them in broad sunshine. (T183) Inferences from sample to population cannot but be fallible, and this is the best we can do, given the logical gap between sample and population.The argument for scepticism with regard to reason concludes not only that such inferences are fallible, that they may be wrong, but more strongly that we have the strongest of reasons for supposing that they...

The mortality and morbidity resulting from noncommunicable diseases including cancer in sub- Saharan Africa are predicted to overtake that of infectious diseases by the year 2030. Esophageal cancer is on the increase in Tanzania. This study estimates risk factors for esophageal cancer, ethical issues and the level of awareness of cancer related services among adults in rural Kilimanjaro. A cross sectional descriptive study was conducted of adults aged 18 years and above in three wards, namely, Kahe, mabogini and Arusha Chini, (...) Moshi Rural District, Kilimanjaro region. Face-to-face interviews were conducted with a total of 419 individuals. The mean age was 36.47 =13.49) years. Of those who participated, 211 were male and 60% reported to have completed primary education. A majority of participants were knowledgeable about esophageal cancer risk factors. Overall, 15% and 23% of the participants reported to have been smoking and drinking alcohol, respectively. Male respondents were almost three times more likely to be smokers as compared to female respondents. Moreover, people who were self-employed were about five times more likely to be smokers as compared to those who were unemployed.. Male respondents were almost two times more likely to be drinkers as compared to female respondents. Overall, the level of awareness of cancer related health services was about 70%. The study findings confirm that despite a good level of knowledge about risk factors for esophageal cancer, the practice of exposure to risk factors is alarmingly high. Awareness of where to seek cancer related health services was high with hospitals been mentioned by the majority though there was low understanding on modalities of treatment among adults in Rural Kilimanjaro. Intervention measures should aim at further increasing knowledge of cancer risk factors and reduce the practice of such risks. Ethical matters including truth telling, ageism and autonomy need to be addressed to improve the perception of cancer related health issues and health seeking behaviour. (shrink)
