The present study examined whether a dissociation among formats for rational numbers can be obtained in tasks that require comparing a number to a non-symbolic quantity. In Experiment 1, college students saw a discrete or else continuous image followed by a rational number, and had to decide which was numerically larger. In Experiment 2, participants saw the same displays but had to make a judgment about the type of ratio represented by the number. The magnitude task was performed more quickly (...) using decimals, whereas the relation task was performed more accurately with fractions. The pattern observed for percentages was very similar to that for decimals. A dissociation between magnitude comparison and relational processing with rational numbers can be obtained when a symbolic number must be compared to a non-symbolic display. (shrink)

Higher education serves many purposes, one of which is to prepare college and university students with the knowledge, skills and dispositions necessary for employment. Some would argue that this is the primary and even sole purpose of collegiate education. However, many also contend that university education is intended to broaden students' minds and enable them to question, investigate and think critically in order to be productive and engaged citizens. Regardless of the lens through which higher education is viewed, within any (...) of these purposes is the need for ethical practices in teaching, learning, student engagement, and overall operational structures. Truly, in every facet of university life, ethical practices exist. If institutions of higher education are the places where, in part, the global future is shaped, then it is imperative that these same organizations be the exemplars of ethical practices. Ethics in Higher Education includes chapters that explore and examine topics such as teaching of ethics, ethical practices on campus, ethics of clinical practices, ethics and leadership in the academy, ethics in hiring practices at colleges/universities, ethics and campus-sponsored research, as well as other topics relevant to higher education. In addition to drawing attention to the successes and challenges regarding ethical practices in higher education, this book aims to encourage future research initiatives and collaborations. (shrink)

Intrateam competition is an inherently social and interactional process, yet it is not often studied as such. Research on competition is mostly limited to studying it as an individual state and assumes that the resulting team outcomes are equivalent across different competition types. Often overlooked in competition research are the means through which competition can lead to constructive outcomes for the team. Constructive competition occurs when the primary motivation is not to win at the expense of others, but rather to (...) make social comparisons and gain knowledge of relative competence. This study furthers insight into constructive competition by studying its interpersonal characteristics as it develops within a team, and its impact on task conflict, perceived performance, and team satisfaction. The conversations of 24 student project teams were recorded over 4 weeks and analyzed, operationalizing competition as an attempt to exert control and influence on the team. Each individual then provided sociometric ratings of perceived performance of each team member, and rated the level of task conflict and satisfaction of the team. The effects of competition on perceived performance and team satisfaction, both directly and indirectly through task conflict, were examined. Findings demonstrated a negative direct effect of competition on the range of perceived performance ratings, and a positive indirect effect of competition on team satisfaction as mediated through task conflict. The study broadens understanding on the construct of competition and underscores the positive implications competition can bring to the teams. (shrink)

The Developmental Systems approach to evolution is defended against the alternative extended replicator approach of Sterelny, Smith and Dickison (1996). A precise definition is provided of the spatial and temporal boundaries of the life-cycle that DST claims is the unit of evolution. Pacé Sterelny et al., the extended replicator theory is not a bulwark against excessive holism. Everything which DST claims is replicated in evolution can be shown to be an extended replicator on Sterelny et al.s definition. Reasons are given (...) for scepticism about the heuristic value claimed for the extended replicator concept. For every competitive, individualistic insight the replicator theorist has a cooperative, systematic blindspot. (shrink)

Background and AimsEnd-of-life discussions can be difficult for seriously ill adolescents and young adults. Researchers aimed to determine whether completing Voicing My CHOiCES —a research-informed advance care planning guide—increased communication with family, friends, or health care providers, and to evaluate the experience of those with whom VMC was shared.MethodsFamily, friends, or HCPs who the AYAs had shared their completed VMC with were administered structured interviews to assess their perception of the ACP discussion, changes in their relationship, conversation quality, and whether (...) the discussion prompted changes in care. Open-ended responses underwent thematic analysis.ResultsOne-month post-completion, 65.1% of AYA had shared VMC completion with a family member, 22.6% with a friend, and 8.9% with an HCP. Among a sample of respondents, family and friends reported a positive change in their relationship with the AYA. Participant descriptions of the experience fell into five themes: positive experience, difficult experience, appreciated a guide to facilitate discussion, provided relief, and created worry/anxiety. Only 1 HCP noted a treatment change. Family, friends, and HCP did not think the AYA would have discussed EoL preferences without completing VMC.ConclusionsVMC has potential to enhance communication about ACP between AYA and their family and friends, though less frequently with HCPs. Participants reported a positive change in their relationship with the AYA after discussing VMC, and described experiencing the conversation as favorable, even when also emotionally difficult.

Developmental systems theory is an attempt to sum up the ideas of a research tradition in developmental psychobiology that goes back at least to Daniel Lehrman’s work in the 1950s. It yields a representation of evolution that is quite capable of accommodating the traditional themes of natural selection and also the new results that are emerging from evolutionary developmental biology. But it adds something else - a framework for thinking about development and evolution without the distorting dichotomization of biological processes (...) into gene and non-gene and the vestiges of the ‘black-boxing’ of developmental processes in the modern synthesis, such as the asymmetric use of the concept of information. Phenomena that are marginalized in current gene-centric conceptions, such as extra-genetic inheritance, niche construction and phenotypic plasticity are placed center stage. (shrink)

Stillbirths are largely excluded from international measures of mortality and morbidity. Zeshan Qureshi and colleagues argue that stillbirth should be higher on the global health agenda.

The conflict between courts and medicine is best shown in the mental health cases requiring judgment of whether a person should be confined, and whether they should be medicated or left free to decide for themselves. In such cases, deprivation of liberty for noncriminal offenders is at question, but if they are released, they may be exposed to injury or injure others. “Clear and convincing” evidence is hard to prove in such cases.The TOPOFF 2 terrorism preparedness exercise was two years (...) in planning, but the courts were involved only seven days before the exercise. Judge Murphy was put in charge of the Circuit Court building and was asked to stop all court proceedings to stop people from going into a building that might have been contaminated. (shrink)

Pregnant women and their interests have been underrepresented in health research. Little is known about issues relevant to women considering research participation during pregnancy. We performed in-depth interviews with 22 women enrolled in either one of two trials sponsored by the National Institutes of Health to assess the safety and immunogenicity of the H1N1 vaccine during pregnancy. Three themes characterized women’s decisions to participate in research: they valued early access to the vaccine, they perceived a safety advantage when participating in (...) research, and they wanted to help advance scientific knowledge. However, there were also some considerations that would disincline them to participate in research—for instance, a significant risk of maternal or fetal harm, the presence of a placebo arm in a study, or a requirement to significantly change planned therapy or behavior. Pregnant women who participated in the H1N1 vaccine trials viewed research favorably, citing its advantages over standard clinical care. These findings emphasize that access to benefit should guide policy for including pregnant women in research. (shrink)

This paper investigates relationships between men’s testosterone and family life in a sample of approximately 350 Jamaican fathers of children 18–24 months of age. The study recognizes the role of testosterone as a proximate mechanism coordinating and reflecting male life history allocations within specific family and cultural contexts. A sample of Jamaican fathers and/or father figures reported to an assessment center for an interview based on a standardized questionnaire and provided a saliva sample for measuring testosterone level. Outcomes measured include (...) subject demographics such as age and relationship status as well as partnership quality and sexuality and paternal attitudes and behavior. The variation in these fathers’ relationship status was not associated with men’s testosterone. Too few stepfathers participated to enable a direct test of the prediction that stepfathers would have higher testosterone than biological fathers, although fathers who reported living with partners’ children did not have higher testosterone than fathers not reporting residing with a non-biological child. Fathers’ relationship quality was negatively related to their testosterone. Measures of paternal attitudes and behavior were not related to fathers’ testosterone. Consistent with previous ethnography, this sample of Jamaican fathers exhibited variable life history profiles, including residential status. We discuss why fathers’ relationship quality was found to be negatively related to their testosterone level, but other predictions were not upheld. (shrink)

Human microbiome research makes causal connections between entire microbial communities and a wide array of traits that range from physiological diseases to psychological states. To evaluate these causal claims, we first examine a well-known single-microbe causal explanation: of Helicobacter pylori causing ulcers. This apparently straightforward causal explanation is not so simple, however. It does not achieve a key explanatory standard in microbiology, of Koch’s postulates, which rely on manipulations of single-microorganism cultures to infer causal relationships to disease. When Koch’s postulates (...) are framed by an interventionist causal framework, it is clearer what the H. pylori explanation achieves and where its explanatory strengths lie. After assessing this ‘simple’, single-microbe case, we apply the interventionist framework to two key areas of microbiome research, in which obesity and mental health states are purportedly explained by microbiomes. Despite the experimental data available, interventionist criteria for explanation show that many of the causal claims generated by microbiome research are weak or misleading. We focus on the stability, specificity and proportionality of proposed microbiome causal explanations, and evaluate how effectively these dimensions of causal explanation are achieved in some promising avenues of research. We suggest some conceptual and explanatory strategies to improve how causal claims about microbiomes are made. (shrink)

This article argues that traditional, regulative principles of research ethics offer insufficient guidance for research in the narrative study of lives. These principles presuppose an implicit epistemology that conceives of research participants as data sources, a conception that is argued not tenable for narrative research. The case is made by drawing on recent discussions of research ethics in the qualitative and narrative research literature. This article shows that narrative ethics is inextricably entwined with epistemological issues--namely, issues of narrative ownership and (...) the multiplicity of narrative meaning. Finally, practical recommendations are made for the ethical treatment of research participants in narrative research. The article concludes by situating our approach with respect to the broad range of contemporary perspectives on research ethics. (shrink)

Developmental systems theory (DST) is a general theoretical perspective on development, heredity and evolution. It is intended to facilitate the study of interactions between the many factors that influence development without reviving `dichotomous' debates over nature or nurture, gene or environment, biology or culture. Several recent papers have addressed the relationship between DST and the thriving new discipline of evolutionary developmental biology (EDB). The contributions to this literature by evolutionary developmental biologists contain three important misunderstandings of DST.

In this brief note, we respond to Gottlieb and Lasser's critical commentary on our work on narrative research ethics. We argue that their concern for privileging voices needs to be balanced against the risk of exploiting some research participants, that conflicts of interest are best resolved through appropriately prioritizing ethical principles and in consultation with others, and that the researcher's ability to protect participants from harm can be enhanced through appropriate clinical training and access to clinical expertise. We welcome Gottlieb (...) and Lasser's specific recommendations for ethical practice in narrative research and encourage further ethical reflection by other researchers in this area. (shrink)

Philosophy of ecology has been slow to become established as an area of philosophical interest, but it is now receiving considerable attention. This area holds great promise for the advancement of both ecology and the philosophy of science. Insights from the philosophy of science can advance ecology in a number of ways. For example, philosophy can assist with the development of improved models of ecological hypothesis testing and theory choice. Philosophy can also help ecologists understand the role and limitations of (...) mathematical models in ecology. On the other side, philosophy of science will be advanced by having ecological case studies as part of the stock of examples. Ecological case studies can shed light on old philosophical topics as well as raise novel issues for the philosophy of science. For example, understanding theoretical terms such as “biodiversity” is important for scientific reasons, but such terms also carry political importance. Formulating appropriate definitions for such terms is thus not a purely scientific matter, and this may prompt a reevaluation of philosophical accounts of defining theoretical terms. We consider some of the topics currently receiving attention in the philosophy of ecology and other topics in need of attention. Our aim is to prompt further exchange between ecology and philosophy of science and to help set the agenda for future work in the philosophy of ecology. The topics covered include: the role of mathematical models, environmental problem formulation, biodiversity, and environmental ethics. (shrink)

Drawing on holistic education and embodied learning, lectio divina empowers teachers and roots students in their own meaning making.

Wealthy individuals stand to gain materially from economic inequality and, moreover, have shaped many organizational and societal practices that perpetuate economic inequality. Thus, they are unlikely allies in the effort to remedy economic inequality. In this article, however, we study the mobilization of a small group of wealthy activists who join underprivileged allies to expose and contest the root causes of wealth consolidation; they offer an instructive alternative to “philanthrocapitalism,” whereby the wealthy give after extreme accumulation. Our study contributes to (...) the growing literature on inequality and organizations by recognizing how inequality is reproduced through organizations, cognizant that efforts to halt this reproduction will likely be contested by the wealthy. Our study examines how advocacy by the wealthy may be challenging, but it may garner attention because it is unexpected. We derive the concept of “privilege work” from our observations of an often awkward and fraught process that enables the wealthy to engage with their own privilege, use their insider knowledge of wealth accumulation as a lever for change, and work respectfully with underprivileged allies rather than invoking superior status.

Purpose Prescription stimulant use as “cognitive enhancers” has been described among undergraduate college students. However, the use of prescription stimulants among future health care professionals is not well characterized. This study was designed to determine the prevalence of prescription stimulant misuse among students at an academic health sciences center. -/- Method Electronic surveys were e-mailed to 621 medical, pharmacy, and respiratory therapy students at East Tennessee State University for four consecutive weeks in fall 2011. Completing the survey was voluntary and (...) anonymous. Surveys asked about reasons for, frequency of, and side effects of nonprescription misuse of prescription stimulants. Given the sensitive material, an opportunity to win one of ten $50 gift cards was used as an incentive. -/- Results Three hundred seventy-two (59.9%) students completed the survey from three disciplines (47.6% medical, 70.5% pharmacy, and 57.6% respiratory therapy). Overall, 11.3% of responders admitted to misusing prescription stimulants. There was more misuse by respiratory therapy students, although this was not statistically significant (10.9% medicine, 9.7% pharmacy, 26.3% respiratory therapy; P = .087). Reasons for prescription stimulant misuse included to enhance alertness/ energy (65.9%), to improve academic performance (56.7%), to experiment (18.2%), and to use recreationally/get high (4.5%). -/- Conclusions Prescription stimulant misuse was prevalent among participating students, but further research is needed to describe prevalence among future health care workers more generally. The implications and consequences of such misuse require further study across professions with emphasis on investigating issues of academic dishonesty (e.g., “cognitive enhancement”), educational quality, and patient safety or health care quality.

HALLIDAY LE and BOUGHTON MA. Nursing Inquiry 2011; 18: 135–142Exploring the concept of uncertain fertility, reproduction and motherhood after cancer in young adult womenThe topics of uncertainty in illness and infertility – as separate entities – are well covered and critiqued in the literature. Conversely, no research has been identified that specifically relates to the uncertain fertility, reproduction and motherhood challenges faced by young women after cancer. Therefore, there has been no opportunity to extend understanding, adequately acknowledge or effectively manage (...) the needs of young women who may face unique reproductive uncertainties after cancer. The objective of this article is to provide a descriptive review of the literature and present what is currently known about uncertainty in the context of cancer and in relation to fertility, reproduction and motherhood. This article sets out the need for an increased research focus into this aspect of cancer survivorship to minimise the unique psychosocial challenges these women often face. Raising awareness and acknowledging the significance and impact of uncertain reproductive capacity on younger women’s psychosocial health will aid cancer co-ordinators, nurses and other health professionals to formulate and deliver timely and appropriate education, management and support.

Clarke and Beck's defense of the theoretical construct “approximate number system” is flawed in serious ways – from biological misconceptions to mathematical naïveté. The authors misunderstand behavioral/psychological technical concepts, such as numerosity and quantical cognition, which they disdain as “exotic.” Additionally, their characterization of rational numbers is blind to the essential role of symbolic reference in the emergence of number.
