The words in children's language learning environments are strongly predictive of cognitive development and school achievement. But how do we measure language environments and do so at the scale of the many words that children hear day in, day out? The quantity and quality of words in a child's input are typically measured in terms of total amount of talk and the lexical diversity in that talk. There are disagreements in the literature whether amount or diversity is the more critical (...) measure of the input. Here we analyze the properties of a large corpus of speech to children and simulate learning environments that differ in amount of talk per unit time, lexical diversity, and the contexts of talk. The central conclusion is that what researchers need to theoretically understand, measure, and change is not the total amount of words, or the diversity of words, but the function that relates total words to the diversity of words, and how that function changes across different contexts of talk.

Nurses’ experiences in, and the overall effectiveness of, widely used alternative‐to‐discipline programs to manage nurses’ substance‐use problems have not been adequately scrutinized. We uncovered the conflicted official and experiential ways of knowing one such alternative‐to‐discipline program in a Canadian province. We explicated this conflict through an institutional ethnography analysis. Ethnographic data from interviews with 12 nurses who were enrolled in an alternative‐to‐discipline treatment program and three program administrators, as well as institutional texts, were analyzed to explore how institutional practices and (...) power relations co‐ordinated and managed nurses’ experiences. Analysis revealed the acritical acceptance of a standardized program not based on current norms of practice. Potential and actual conflicts of interest, power imbalances, and prevailing corporate interests were rife. Nurses were not afforded the same rights to quality ethical health care as other citizens. ‘Expert’ physicians’ knowledge was privileged while nurses’ knowledge was subordinated. Conclusions were that regulatory bodies cannot rely on the taken‐for‐granted standardized treatment model in widespread use. Individualized treatment alternatives reflecting current, scientific evidence must be offered to nurses, and nurses’ knowledge, expertise, and experiences need to be included in decision‐making processes in these programs.

We consider the moral and social ingredients in physicians' relationships with patients of diminished capacity by considering certain claims made about friendship and the physician's role. To assess these claims we look at the life context of two patients as elaborated examples provided in two novels: Woman on the Edge of Time (1976) by Marge Piercy, a radical feminist; and It's Hard to Leave While the Music's Playing (1977) by I. S. Cooper, a prominent physician-researcher. At issue is how the (...) doctor-patient relationship should be structured. In question is whether the physician's friendship and professional expertise, together with the diminished capacity of the patient, authorize medical paternalism. From our examination, we find compelling insights against appealing to friendship both in good doctor-patient relationships and in more typical, not-so-good ones. (shrink)

Frequency effects are pervasive in studies of language, with higher frequency words being recognized faster than lower frequency words. However, the exact nature of frequency effects has recently been questioned, with some studies finding that contextual information provides a better fit to lexical decision and naming data than word frequency ( Adelman et al., 2006 ). Recent work has cemented the importance of these results by demonstrating that a measure of the semantic diversity of the contexts that a word occurs (...) in provides a powerful measure to account for variability in word recognition latency ( Johns et al., 2012, 2015 ; Jones et al., 2012 ). The goal of the current study is to extend this measure to examine bilingualism and aging, where multiple theories use frequency of occurrence of linguistic constructs as central to accounting for empirical results ( Gollan et al., 2008 ; Ramscar et al., 2014 ). A lexical decision experiment was conducted with four groups of subjects: younger and older monolinguals and bilinguals. Consistent with past results, a semantic diversity variable accounted for the greatest amount of variance in the latency data. In addition, the pattern of fits of semantic diversity across multiple corpora suggests that bilinguals and older adults are more sensitive to semantic diversity information than younger monolinguals.

Background: Discussions about medical errors facilitate professional learning for physicians and may provide emotional support after an error, but little is known about physicians’ attitudes and practices regarding error discussions with colleagues.Methods: Survey of faculty and resident physicians in generalist specialties in Midwest, Mid-Atlantic and Northeast regions of the US to investigate attitudes and practices regarding error discussions, likelihood of discussing hypothetical errors, experience role-modelling error discussions and demographic variables.Results: Responses were received from 338 participants . In all, 73% of (...) respondents indicated they usually discuss their mistakes with colleagues, 70% believed discussing mistakes strengthens professional relationships and 89% knew at least one colleague who would be a supportive listener. Motivations for error discussions included wanting to learn whether a colleague would have made the same decision , wanting colleagues to learn from the mistake and wanting to receive support . Given hypothetical scenarios, most respondents indicated they would likely discuss an error resulting in no harm , minor harm or major harm . Fifty-seven percent of physicians had tried to serve as a role model by discussing an error and role-modelling was more likely among those who had previously observed an error discussion .Conclusions: Most generalist physicians in teaching hospitals report that they usually discuss their errors with colleagues, and more than half have tried to role-model discussions. However, a significant number of these physicians report that they do not usually discuss their errors and some do not know colleagues who would be supportive listeners. (shrink)

Although mutually advantageous cooperative strategies might be an apt account of some societies, other moral systems might be needed among certain groups and contexts. In particular, in a duty-based moral system, people do not behave morally with an expectation for proportional reward, but rather, as a fulfillment of debt owed to others. In such systems, mutualistic motivations are not necessarily a key component of morality.

Nanomaterials have the promise of revolutionizing current treatment and diagnosis of diseases, which has led to 33 nanotherapeutics drugs currently on the market and many more in various stages of clinical trials. With an increasing number of products available and in development, along with the unique, emergent properties of the nanoparticle therapeutics themselves, regulatory agencies are now faced with decisions regarding the regulation of such novel technologies. Regulatory guidance, particularly in pre-clinical stages, has the potential to facilitate quick and safe (...) development of these novel materials, but new regulation beyond what is currently in place must be justified in a clear and distinctive toxic response. Herein, we examine literature that compares and correlates in vivo and in vitro nanotoxicity studies to gain a deeper understanding of the modes of nanoparticle toxicity. Additionally, this comparison aims to identify clear and unique toxicity responses caused by nanoparticles, which informs our perspective on pre-clinical nanotherapeutic oversight. (shrink)

Much of the focus of the published 2011 symposium that inspired this work focused on the question, “When have you reduced risk enough to move from bench/animal studies to ‘first in-human’ studies?” Building applied research ethics related to nanotherapeutics requires bench and clinical scientists to have a clear vision about how to test nanotherapeutic safety, and it is clear that there is still much to be considered at the steps before “in-human” assessment. Herein, the perspective of the bench scientist is (...) brought to bear on using in vivo and in vitro models to assess the safety of nanotherapeutics. Much of this work falls under the purview of the field of nanotoxicology that aims to understand the toxicological impact of engineered nanoscale materials. Engineered nanomaterials include a wide variety of materials that are manipulated and controlled on the nanoscale level where, typically, the nanoparticle or nanomaterial has some dimension that is less than 100 nm.

OBJECTIVES: To study the resuscitation preferences, choice of decision-maker, views on the seeking of patients' wishes and determinants of these of elderly hospital in-patients. DESIGN: Questionnaire administered on admission and prior to discharge. SETTING: Two acute geriatric medicine units (Southampton and Poole). PARTICIPANTS: Two hundred and fourteen consecutive consenting mentally competent patients admitted to hospital as emergencies. RESULTS: Resuscitation was wanted by 60%, particularly married and functionally independent patients and those who had not already considered it. Not wanted resuscitation was (...) associated with lack of social contacts. Sixty-seven per cent welcomed enquiry about their preferences and 78% wanted participation in decision, 43% as sole decision-maker. Wishing to choose oneself was associated with not wanting resuscitation, prior knowledge of it, and lack of a spouse. Patients' opinions remained stable during their admission. CONCLUSIONS: Discussion of resuscitation is practical on hospital admission without causing distress and the views expressed endure through the period of hospitalisation. Elderly patients' attitudes depend partly on personal health and social circumstances. This may assist doctors when patients are unable to participate themselves. (shrink)

This article evaluates the effect of different human resource management (HRM) practices on organizations’ environmental performance. We develop a model to evaluate the influence of a broad range of HRM practices, including environmental performance criteria in managers’ performance evaluations and two types of internal corporate social responsibility (CSR) practices: socially responsible employee benefits and corporate volunteering practices. To this end, we analyze a sample of 142 manufacturing companies that have completed B Lab’s Impact Assessment process to certify their environmental performance. (...) The results show that including environmental criteria in a higher proportion of managers’ performance evaluations directly impacts organizations’ environmental performance and strengthens the positive effect of other environmental management practices. The findings also demonstrate the direct effects of both types of CSR practices on an organization’s environmental performance. Our study advances recent work on Green HRM and CSR by identifying the specific HRM practices that allow organizations to move from being part of the world’s environmental problem to being part of the solution.

We show that if κ is a weakly compact cardinal, then $\left( \matrix \kappa ^{+} \\ \kappa\endmatrix \right)\rightarrow \left(\left( \matrix \alpha \\ \kappa \endmatrix \right)_{m}\left( \matrix \kappa ^{n} \\ \kappa \endmatrix \right)_{\mu}\right)^{1,1}$ for any ordinals α < κ⁺ and µ < κ, and any finite ordinals m and n. This polarized partition relation represents the statement that for any partition $\kappa \times \kappa ^{+}=\underset i<m\to{\bigcup }K_{i}\cup \underset j<\mu \to{\bigcup }L_{j}$ of κ × κ⁺ into m + µ pieces either there (...) are A ∈ [κ]κ, B ∈ [κ⁺]α, and i < m with A × B ⊆ Ki or there are C ∈ [κ]κ, D ∈ [κ⁺]α, and j < μ with C × D ⊆ Lj. Related results for measurable and almost measurable κ are also investigated. Our proofs of these relations involve the use of elementary substructures of set models of large fragments of ZFC.

It is often asserted that even our own past is a foreign country: the ideas of past thinkers are, in some ways, alien to us today. For the European historian of non- European philosophy, not only is the past held to be a different country, but it is also the past ofadifferentcountry. This is both convenient and problematic all at once. The historian of non- European philosophy faces a double separation from his/her subject matter; she is both a foreigner and (...) an alien. In this paper, I approach questions of how this historian should orientate herself towards her subject, and why she should care about it at all. (shrink)

Amid the unrest, dislocation, and uncertainty of seventeenth-century Europe, readers seeking consolation and assurance turned to philosophical and scientific books that offered ways of conquering fears and training the mind—guidance for living a good life. _The Good Life in the Scientific Revolution_ presents a triptych showing how three key early modern scientists, René Descartes, Blaise Pascal, and Gottfried Leibniz, envisioned their new work as useful for cultivating virtue and for pursuing a good life. Their scientific and philosophical innovations stemmed in (...) part from their understanding of mathematics and science as cognitive and spiritual exercises that could create a truer mental and spiritual nobility. In portraying the rich contexts surrounding Descartes’ geometry, Pascal’s arithmetical triangle, and Leibniz’s calculus, Matthew L. Jones argues that this drive for moral therapeutics guided important developments of early modern philosophy and the Scientific Revolution. (shrink)

In recent years, educational institutions have started using the tools of commercial data analytics in higher education. By gathering information about students as they navigate campus information systems, learning analytics “uses analytic techniques to help target instructional, curricular, and support resources” to examine student learning behaviors and change students’ learning environments. As a result, the information educators and educational institutions have at their disposal is no longer demarcated by course content and assessments, and old boundaries between information used for assessment (...) and information about how students live and work are blurring. Our goal in this paper is to provide a systematic discussion of the ways in which privacy and learning analytics conflict and to provide a framework for understanding those conflicts. -/- We argue that there are five crucial issues about student privacy that we must address in order to ensure that whatever the laudable goals and gains of learning analytics, they are commensurate with respecting students’ privacy and associated rights, including (but not limited to) autonomy interests. First, we argue that we must distinguish among different entities with respect to whom students have, or lack, privacy. Second, we argue that we need clear criteria for what information may justifiably be collected in the name of learning analytics. Third, we need to address whether purported consequences of learning analytics (e.g., better learning outcomes) are justified and what the distributions of those consequences are. Fourth, we argue that regardless of how robust the benefits of learning analytics turn out to be, students have important autonomy interests in how information about them is collected. Finally, we argue that it is an open question whether the goods that justify higher education are advanced by learning analytics, or whether collection of information actually runs counter to those goods.

Situation selection involves choosing situations based on their likely emotional impact and may be less cognitively taxing or challenging to implement compared to other strategies for regulating emotion, which require people to regulate their emotions “in the moment”; we thus predicted that individuals who chronically experience intense emotions or who are not particularly competent at employing other emotion regulation strategies would be especially likely to benefit from situation selection. Consistent with this idea, we found that the use of situation selection (...) interacted with individual differences in emotional reactivity and competence at emotion regulation to predict emotional outcomes in both a correlational and an experimental field study. Taken together, the findings suggest that situation selection is an effective strategy for regulating emotions, especially for individuals who otherwise struggle to do so. (shrink)

The activities of the life sciences are essential to provide solutions for the future, for both individuals and society. Society has demanded growing accountability from the scientific community as implications of life science research rise in influence and there are concerns about the credibility, integrity and motives of science. While the scientific community has responded to concerns about its integrity in part by initiating training in research integrity and the responsible conduct of research, this approach is minimal. The scientific community (...) justifies itself by appealing to the ethos of science, claiming academic freedom, self-direction, and self-regulation, but no comprehensive codification of this foundational ethos has been forthcoming. A review of the professional norms of science and a prototype code of ethics for the life sciences provide a framework to spur discussions within the scientific community to define scientific professionalism. A formalization of implicit principles can provide guidance for recognizing divergence from the norms, place these norms within a context that would enhance education of trainees, and provide a framework for discussing externally and internally applied pressures that are influencing the practice of science. The prototype code articulates the goal for life sciences research and the responsibilities associated with the freedom of exploration, the principles for the practice of science, and the virtues of the scientists themselves. The time is ripe for scientific communities to reinvigorate professionalism and define the basis of their social contract. Codifying the basis of the social contract between science and society will sustain public trust in the scientific enterprise. (shrink)

Objective We conducted a process evaluation to (a) assess the effectiveness of a new problem-based learning curriculum designed to teach professionalism and scientific integrity to biomedical graduate students and (b) modify the course to enhance its relevance and effectiveness. The content presented realistic cases and issues in the practice of science, to promote skill development and to acculturate students to professional norms of science. Method We used 5-step Likert-scaled questions, open-ended questions, and interviews of students and facilitators to assess curricular (...) effectiveness. Results Both facilitators and students perceived course objectives were achieved. For example, respondents preferred active learning over lectures; both faculty and students perceived that the curriculum increased their understanding of norms, role obligations and responsibilities of professional scientists. They also reported an increased ability to identify ethical situations and felt that they had developed skills in moral reasoning and effective group work. Conclusions These data helped to improve course implementation and instructional material. For example, to correct a negative perception that this was an ‘ethics’ course, we redesigned case debriefing activities to reinforce learning objectives and important skills. We refined cases to be more engaging and relevant for students, and gave facilitators more specific training and resources for each case. The problem-based learning small group strategy can stimulate an environment whereby participants are more aware of ethical implications of science, and increase their socialisation and open communication about professional behaviour.

There is increasing concern about “surveillance capitalism,” whereby for-profit companies generate value from data, while individuals are unable to resist (Zuboff 2019). Non-profits using data-enabled surveillance receive less attention. Higher education institutions (HEIs) have embraced data analytics, but the wide latitude that private, profit-oriented enterprises have to collect data is inappropriate. HEIs have a fiduciary relationship to students, not a narrowly transactional one (see Jones et al, forthcoming). They are responsible for facets of student life beyond education. In addition (...) to classrooms, learning management systems, and libraries, HEIs manage dormitories, gyms, dining halls, health facilities, career advising, police departments, and student employment. HEIs collect and use student data in all of these domains, ostensibly to understand learner behaviors and contexts, improve learning outcomes, and increase institutional efficiency through “learning analytics” (LA). ID card swipes and Wi-Fi log-ins can track student location, class attendance, use of campus facilities, eating habits, and friend groups. Course management systems capture how students interact with readings, video lectures, and discussion boards. Application materials provide demographic information. These data are used to identify students needing support, predict enrollment demands, and target recruiting efforts. These are laudable aims. However, current LA practices may be inconsistent with HEIs’ fiduciary responsibilities. HEIs often justify LA as advancing student interests, but some projects advance primarily organizational welfare and institutional interests. Moreover, LA advances a narrow conception of student interests while discounting privacy and autonomy. Students are generally unaware of the information collected, do not provide meaningful consent, and express discomfort and resigned acceptance about HEI data practices, especially for non-academic data (see Jones et al. forthcoming). The breadth and depth of student information available, combined with their fiduciary responsibility, create a duty that HEIs exercise substantial restraint and rigorous evaluation in data collection and use.

Mounting evidence suggests that endorsement of psychological continuity and the afterlife increases with age. This developmental change raises questions about the cognitive biases, social representations, and cultural input that may support afterlife beliefs. To what extent is there similarity versus diversity across cultures in how people reason about what happens after death? The objective of this study was to compare beliefs about the continuation of biological and psychological functions after death in Tanna, Vanuatu, and the United States. Children, adolescents, and (...) adults were primed with a story that contained either natural or supernatural cues. Participants were then asked whether or not different biological and psychological processes continue to function after death. We predicted that across cultures individuals would be more likely to endorse the continuation of psychological processes over biological processes and that a theistic prime would increase continuation responses regarding both types of process. Results largely supported predictions; U.S. participants provided more continuation responses for psychological than biological processes following both the theistic and non-theistic primes. Participants in Vanuatu, however, provided more continuation responses for biological than psychological processes following the theistic prime. The data provide evidence for both cultural similarity and variability in afterlife beliefs and demonstrate that individuals use both natural and supernatural explanations to interpret the same events.

Higher education institutions are mining and analyzing student data to effect educational, political, and managerial outcomes. Done under the banner of “learning analytics,” this work can—and often does—surface sensitive data and information about, inter alia, a student’s demographics, academic performance, offline and online movements, physical fitness, mental wellbeing, and social network. With these data, institutions and third parties are able to describe student life, predict future behaviors, and intervene to address academic or other barriers to student success (however defined). Learning (...) analytics, consequently, raise serious issues concerning student privacy, autonomy, and the appropriate flow of student data. We argue that issues around privacy lead to valid questions about the degree to which students should trust their institution to use learning analytics data and other artifacts (algorithms, predictive scores) with their interests in mind. We argue that higher education institutions are paradigms of information fiduciaries. As such, colleges and universities have a special responsibility to their students. In this article, we use the information fiduciary concept to analyze cases when learning analytics violate an institution’s responsibility to its students. (shrink)

“Big Data” and data analytics affect all of us. Data collection, analysis, and use on a large scale is an important and growing part of commerce, governance, communication, law enforcement, security, finance, medicine, and research. And the theme of this symposium, “Individual and Informational Privacy in the Age of Big Data,” is expansive; we could have long and fruitful discussions about practices, laws, and concerns in any of these domains. But a big part of the audience for this symposium is (...) students and faculty in higher education institutions (HEIs), and the subject of this paper is data analytics in our own backyards. Higher education learning analytics (LA) is something that most of us involved in this symposium are familiar with. Students have encountered LA in their courses, in their interactions with their law school or with their undergraduate institutions, instructors use systems that collect information about their students, and administrators use information to help understand and steer their institutions. More importantly, though, data analytics in higher education is something that those of us participating in the symposium can actually control. Students can put pressure on administrators, and faculty often participate in university governance. Moreover, the systems in place in HEIs are more easily comprehensible to many of us because we work with them on a day-to-day basis. Students use systems as part of their course work, in their residences, in their libraries, and elsewhere. Faculty deploy course management systems (CMS) such as Desire2Learn, Moodle, Blackboard, and Canvas to structure their courses, and administrators use information gleaned from analytics systems to make operational decisions. If we (the participants in the symposium) indeed care about Individual and Informational Privacy in the Age of Big Data, the topic of this paper is a pretty good place to hone our thinking and put into practice our ideas.
