Happy people often fail to elaborate on persuasive arguments, while people in sad moods tend to scrutinise messages in greater detail. According to some motivational accounts, however, happy people will elaborate a message if they believe it might maintain their positive mood. The present research extends this reasoning by demonstrating that happy people will elaborate arguments from message presenters that convey positive hedonic attributes (i.e., source likeability). In a pilot study, we show that happy people believe persuasive messages from a (...) likeable source will be mood maintaining. The results of Study 1 demonstrate that these expectancies have important message-processing implications. In Study 1, sad participants elaborated arguments from both likeable and dislikeable sources, while happy participants only elaborated arguments from a likeable source. Consistent with motivational explanation of these effects, in Study 2, happy participants elaborated arguments from a likeable source when not distracted, but used likeability as a heuristic when distracted with a cognitive-load manipulation. Implications of these results for understanding the effects of mood on processing strategy, limitations, and directions for future research are discussed. (shrink)

It is well-known that the invocation of `equilibrium processes' in thermodynamics is oxymoronic. However, their prevalence and utility, particularly in elementary accounts, presents a problem. We consider a way in which their role can be played by sets of sequences of processes demarcated by curves carrying the property of accessibility. We also examine the vexed question of whether equilibrium processes are necessarily reversible and the revision of this property in relation to sets of sequences of such processes.

Purpose Children are becoming heavy users of communication and information technologies from an early age. These technologies carry risks to which children may be exposed. In collaboration with the Israel Ministry of Education, the authors launched a week-long safe online awareness program for school children in 257 elementary and middle schools in Israel. Each class independently composed a safe and ethical code of online behavior following two classroom debate sessions. The purpose of this study was to analyze these codes and (...) learn how school children perceive and understand the proper use of the network using thematic analysis. Design/methodology/approach A total of 8,181 students between the ages of 8 and 14 years in 303 classes from 257 schools participated in the program. These classes composed 303 ethical codes, which were decomposed into 2,201 elements. Using mixed-methods research combining quantitative and qualitative methodologies, the elements of the ethical codes were analyzed, interpreted, and classified to identify the dominant themes and discourses used by the students when addressing issues related to safe online use. Findings Findings indicate that Israeli students are aware of the dangers and risks of the internet, and these concerns are reflected in their own ethical codes. The students discouraged online self-exposure and encouraged precautions and wariness towards members of out-groups. The themes included sentences which asked for responsible, appropriate, and lawful use, expressed concern about privacy issues, and stated the need for adult involvement. Most of them reflected an “us against them ” perspective. Originality/value The current study presents an innovative “bottom-up” program based on wisdom of the crowd approach, that can be implemented in schools internationally in order to encourage reflexivity and teach children the necessary skills for safe online experiences. In addition, this study analyses the school children’s own views of the dangers of social media and learn about their perspective and understanding of internet use. (shrink)

Graphical AbstractThe fungus Neurospora comprises a novel model for testing hypotheses involving the role of sex and reproduction in eukaryotic genome evolution. Its variation in reproductive mode, lack of sex-specific genotypes, availability of phylogenetic species, and young sex-regulating chromosomes make research in this genus complementary to animal and plant models.

We analyse how memes construct networks of feminist critique and response, mobilising the derisive laughter that energises current feminisms. Using the 2012 case of the ‘Binders Full of Women’ meme, we argue that feminist memes create online spaces of consciousness raising and community building. The timeliness, humorous affect and media techné of meme propagators become significant infrastructures for feminist critique, what we term ‘doing feminism in the network’. If the Internet is particularly good at facilitating the diffusion of feminist jokes, (...) as others argue, we illustrate how the networking and distribution capacities of social media platforms such as Tumblr, Facebook and the online shopping site Amazon.com also cultivate new modes of feminist cultural critique and models of political agency for practising feminism through meme production and propagation.

The Boltzmann and Gibbs approaches to statistical mechanics have very different definitions of equilibrium and entropy. The problems associated with this are discussed and it is suggested that they can be resolved, to produce a version of statistical mechanics incorporating both approaches, by redefining equilibrium not as a binary property but as a continuous property measured by the Boltzmann entropy and by introducing the idea of thermodynamic-like behaviour for the Boltzmann entropy. The Kac ring model is used as an example (...) to test the proposals. (shrink)

This paper presents an in-depth analysis of the anatomy of both thermodynamics and statistical mechanics, together with the relationships between their constituent parts. Based on this analysis, using the renormalization group and finite-size scaling, we give a definition of a large but finite system and argue that phase transitions are represented correctly, as incipient singularities in such systems. We describe the role of the thermodynamic limit. And we explore the implications of this picture of critical phenomena for the questions of (...) reduction and emergence. (shrink)

Simple models have played an important role in the discussion of foundational issues in statistical mechanics. Among them the spin-echo system is of particular interest since it can be realized experimentally. This has led to inferences being drawn about approaches to the foundations of statistical mechanics, particularly with respect to the use of coarse-graining. We examine these claims with the help of computer simulations.

We show that both positive and negative absolute temperatures and monotonically increasing and decreasing entropy in adiabatic processes are consistent with Carathéodory's version of the second law and we explore the modifications of the Kelvin–Planck and Clausius versions which are needed to accommodate these possibilities. We show, in part by using the equivalence of distributions and the canonical distribution, that the correct microcanonical entropy, is the surface (Boltzmann) form rather than the bulk (Gibbs) form thereby providing for the possibility of (...) negative temperatures and we counter the contention on the part of a number of authors that the surface entropy fails to satisfy fundamental thermodynamic relationships.

OBJECTIVES: In treating critically ill neonates, situations occasionally arise in which aggressive medical treatment prolongs the inevitable death rather than prolonging life. Decisions as to limitation of neonatal medical intervention remain controversial and the primary responsibility of the generally unprepared family. This research was designed to study response patterns of expectant mothers towards treatment of critically ill and/or malformed infants. DESIGN/SETTING: Attitudes were studied via comprehensive questionnaires divided into three sections: 1-Sociodemographic data and prior personal experience with perinatal problems; 2-Theoretical (...) philosophical principles used in making medical ethical decisions; and 3-Hypothetical case scenarios with choices of treatment options. SUBJECTS AND RESULTS: Six hundred and fifty pregnant women were studied. Maternal birthplace (p = 0.005) and level of religious observance (p = 0.02) were strongly associated with the desire for maximally aggressive medical intervention in the hypothetical case scenario. Specific personal experiences such as infertility problems, previous children with serious mental or physical problems were not correlated with the selection of different treatment choices. Of the theoretical principles studied, only the desire to preserve life at all costs was significantly associated with the choice for maximal medical treatment (p = 0.003). CONCLUSIONS: Maternal ethnocultural background and philosophical principles more profoundly influenced medical ethical decision-making than did specific personal life experiences. (shrink)

OBJECTIVE: We studied and compared the attitudes of pregnant women v new mothers in an attempt to confirm changing patterns of maternal response towards medical ethical decision making in critically ill or malformed neonates. DESIGN: Data were obtained by questionnaires divided into three sections: 1. sociodemographic; 2. Theoretical principles which might be utilised in the decision-making process; 3. Hypothetical case scenarios, each followed by possible treatment options. RESULTS: Pregnant women (n = 545) consistently requested less aggressive medical intervention for the (...) hypothetical cases than did new mothers (n = 250) [Trisomy 18: 57% v 42%; p = 0.0004; Asphyxia: 75% v 63%; p = 0.0017; Down's syndrome 81% v 62%; p = 0.0001; LBW 85% v 75%; p = 0.004]. Significant differences were also observed in the responses to the theoretical principles, with pregnant women attributing less importance to preserving life at all cost, while being more concerned with physical and emotional pain and suffering, with financial cost, and with the infant's potential for future productivity.

I propose conceptualizing stress in standard phylogenetic terms of stress characters, as well as stress phenotypes, as a way to improve stress research involving nonhuman models. PMID: 38626744.

Jackendoff's position with respect to categories is unclear. Positing categories is implausible in several respects; it makes the binding problem in language seem more massive than it actually is; and it makes it difficult to explain language acquisition. Waiting for connectionism to fulfill its promise, a different track is sketched which is residually symbolic, exemplarist, and analogy-based.

Objective: Appropriate reactivity to emotional facial expressions, even if these are seen whilst we are engaged in another activity, is critical for successful social interaction. Children with conduct problems (CP) and high levels of callous-unemotional (CU) traits are characterized by blunted reactivity to other people's emotions, while children with CP and low levels of CU traits can over-react to perceived emotional threat. No study to date has compared children with CP and high vs. low levels of CU traits to typically (...) developing (TD) children or each other, using a task that assesses attentional capture by irrelevant emotional faces. -/- Method: All participants performed an attentional capture task in which they were asked to judge the orientation of a single male face that was displayed simultaneously with two female faces. Three types of trials were presented, trials with all neutral faces, trials with an emotional distractor face and trials with an emotional target face. Fifteen boys with CP and high levels of CU traits, 17 boys with CP and low levels of CU traits and 17 age and ability matched TD boys were included in the final study sample. -/- Results: Compared to TD children and children with low levels of CU traits, children with CP and high levels of CU traits showed reduced attentional capture by irrelevant emotional faces. -/- Conclusions: This study is the first to demonstrate a different pattern in emotional attentional capture in children with CP depending on their level of CU traits.

A key question in understanding visual awareness is whether any single cortical area is indispensable. In a transcranial magnetic stimulation experiment, we show that observers' awareness of activity in extrastriate area VS depends on the amount of activity in striate cortex (Vl). From the timing and pattern of effects, we infer that back-projections from extrastriate cortex influence information content in Vl, but it is Vl that determines whether that information reaches awareness.

This paper presents a constructivist grounded theory on the decision-making process that UK home and alternative educators undertake and the related influencing factors. Twenty-one participants from a diverse range of backgrounds were interviewed between one and three times over a two-year period. Some were current home and alternative educators and others were undecided, or had changed their minds about home educating. The core process is entitled ‘Stepping out of the system?’ It was constructed from three main categories: attitudinal direction, surveying (...) the landscape and negotiating obstacles. Parents have opinions of school that developed before they began to consider how to educate their child; attitudes which are affect laden and guide the process of information gathering. The surveying the landscape stage involves both formal research and informal methods such as hearing the views of others and acting upon their own feelings. The final stage, negotiating obstacles, involves finding practical solutions to barriers they may face. The grounded theory is enriched and deepened by Reddy’s (2010) concept of emotional refuges.

Carrie Figdor presents a critical assessment of how psychological terms are used to describe the non-human biological world. She argues against the anthropocentric attitude which takes human cognition as the standard against which non-human capacities are measured, and offers an alternative basis for naturalistic explanation of the mind.

Digital phenotyping for mental health is an emerging trend which uses digital data, derived from mobile applications, wearable technologies and digital sensors, to measure, track and predict the mental health of an individual. Digital phenotyping for mental health is a growing, but as yet underexamined, field. As we will show, the rapid growth of digital phenotyping for mental health raises crucial questions about the values that underpin and are reinforced by this technology, as well as regarding to whom it may (...) become valuable. In this commentary, we explore these questions by focusing on the construction of value across two interrelated domains: user experience and epistemologies on the one hand, and issues of data and ownership on the other. In doing so, we demonstrate the need for a deeper ethical and epistemological engagement with the value assumptions that underpin the promise of digital phenotyping for mental health. (shrink)

Recent work asked if visual cues facilitate word segmentation in adults and infants. While adults showed better word segmentation when presented with a regular visual cue, infants did not. This difference was attributed to infants' lack of understanding that objects have labels. Alternatively, infants’ performance could reflect their difficulty with tracking and integrating multiple multimodal cues. We contrasted these two accounts by looking at the effect of visual cues on word segmentation in adults and across childhood. We found that older (...) children benefitted from the regular visual cues, but younger children, who already knew that objects have labels, did not. Knowing that objects have labels was not enough to use visual cues as an aid for segmentation. These findings show that the ability to integrate multimodal cues develops during childhood, and it is not yet adult-like in children. (shrink)

The introduction of respiratory machines in the 1950s may have saved the lives of many, but it also challenged the notion of death itself. This development endowed “machines” with the power to form a unique ontological creature: a live body with a “dead” brain. While technology may be blamed for complicating things in the first place, it is also called on to solve the resulting quandaries. Indeed, it is not the birth of the “brain-dead” that concerns us most, but rather (...) its association with a web of epistemological and ethical considerations, where technology plays a central role. The brain death debate in Israel introduces highly sophisticated religious thought and authoritative medical expertise. At focus are the religious acceptance and rejection of brain death by a technologically savvy group of rabbis whose religious doctrine––along with a particular form of religious reasoning––is used to support the truth claims made from the scientific community but challenge the ways in which they are made credible. In our case, brain death as “true” death is made religiously viable with the very use of technological apparatus and scientific rhetoric that stand at the heart of the scientific ethos. (shrink)

This book offers a novel understanding of Israeli bioethics that is a milestone in the comparative literature of bioethics. Bringing together a range of experts, the book's interdisciplinary structure employs a contemporary, sociopolitical-oriented approach to bioethics issues, with an emphasis on empirical analysis, that will appeal not only to scholars of bioethics, but also to students of law, medicine, humanities, and social sciences around the world. Its focus on the development of bioethics in Israel makes it especially relevant to scholars (...) of Israeli society- both in and out of Israel-as well as medical practitioners and health policymakers in Israel.

What makes modern law and politics modern? What makes the question of "modernity" so central to our understanding of contemporary law and politics? To offer one possible answer to these questions this study examines the changing relationship between animals and humans and, more specifically, the new regulation of the slaughterhouse in turn of the century Germany. If humans and animals meet in the modern agora it is neither because animals are now perceived as more human-like, as champions of progress would (...) have it, nor because humans are perceived as more animal-like, as critics of modernity would suggest. Rather, both animals and humans have undergone a radical transformation, which has put them on the same plane. If life is that which humans and animals share in common, and politics is that which sets them apart, the history of animal laws suggests that modernity entails the radical transformation of both life and politics. This Article strives to understand this change through the transformation of both politics and life into processes, i.e., into that which can be scientifically known and thus manipulated. The different strategies of reformers of slaughtering as well as their opponents are analyzed in light of this fundamental transformation. (shrink)

“Challenging the utility of polygenic scores for social science” is a compelling but limited critique. Phenotypic development is sensitive to both initial conditions and all subsequent states – from conception to senescence. Thus, gene-centric analyses are misleading (and often meaningless) because gene products are transformed, and their phenotypic ‘effects' combined and attenuated with successive propagations from molecular and cellular contexts to organismal and social environments.

Carrie Jenkins presents a new account of arithmetical knowledge, which manages to respect three key intuitions: a priorism, mind-independence realism, and empiricism. Jenkins argues that arithmetic can be known through the examination of empirically grounded concepts, non-accidentally accurate representations of the mind-independent world.

Character strengths are widely studied positive traits considered to be “values in action,” reflecting morally valued virtues. They are hypothesized to serve as pathways to the manifestation of values in life for the benefit of individuals and societies. However, there is surprisingly limited theoretical writing and empirical research on the expected links of character strengths with specific values [e.g., as defined by Schwartz ] or on character strengths as the pathway for behavioral and social manifestations of these values. In this (...) paper, we delineate theoretical links between the two theories and outline their implications. We then provide an initial empirical examination of a specific character strength – gratitude, as a pathway from Schwartz’s self-transcendence values to prosocial behavior and peer acceptance, in two samples of adolescents. The findings indicated that most pathways were significant, providing initial support for the theoretical model. However, in one of the samples, the indirect path from self-transcendence values to prosocial behavior was only marginally significant. Taken together, the findings point to the need for further research on the role of character strengths in creating a pathway from values to various social outcomes. (shrink)
