RAID-II is a high-bandwidth, network-attached storage server designed and implemented at the University of California at Berkeley. In this paper, we measure the performance of RAID-II and evaluate various architectural decisions made during the design process. We first measure the end-to-end performance of the system to be approximately 20 MB/s for both disk array reads and writes. We then perform a bottleneck analysis by examining the performance of each individual subsystem and conclude that the disk subsystem limits performance. By adding (...) a custom interconnect board with a high-speed memory and bus system and parity engine, we are able to achieve a performance speedup of 8 to 15 over a comparative system using only off-the-shelf hardware.

This paper examines the origins and influences of the introduction of longitudinal student data-sets as a way of gaining insight into the operation of American schools and as a tool for policy-makers. The paper argues that the creation of this new form of data in the 1960s and 1970s represented a relatively new way of thinking about American schools that allowed policy-makers to view the American education system as relatively uniform and the goal of policy to optimize its function. The (...) use of data in this way produced, somewhat paradoxically, a higher precision and more distorted view of the American schooling. The detailed picture provided by these data-sets offered policy-makers new and important insights into the pathways through schooling of individual students while at the same time presented scholars and policy-makers with an increasingly abstract and decontextualized view of the American education system as a whole. That is to say, to view the system uniform and national terms. The upshot... (shrink)

This article focuses on the association between the beliefs of small business owners and managers and their support for the community. Qualitative and quantitative data are utilized in an exploratory examination of two rationales for socially responsible behavior and of two kinds of support. Analyses show that the belief in strengthening the community as an important strategy for business success is positively associated with the provision of nonrisky and risky support. Risky support may threaten short-term business success. However, the belief (...) that a good public image is important for business success is negatively or not significantly associated with either risky or nonrisky support for the community. Findings uphold the position that there are significant variations in enlightened self-interest rationales that are differentially associated with business social performance among small business operators and demonstrate the usefulness of disaggregating social performance into risky and nonrisky variations.

_In _Absent from School_, Gottfried and Hutt offer a comprehensive and timely resource for educators and policy makers seeking to understand the scope, impact, and causes of chronic student absenteeism._ The editors present a series of studies by leading researchers from a variety of disciplines that address which students are missing school and why, what roles schools themselves play in contributing to or offsetting patterns of absenteeism, and ways to assess student attendance for purposes of school accountability. The contributors examine (...) school-based initiatives that focus on a range of issues, including transportation, student health, discipline policies, and protections for immigrant students, as well as interventions intended to improve student attendance. Only in the past two or three years has chronic absenteeism become the focus of attention among policy makers, civil rights advocates, and educators. _Absent from School_ provides the first critical, systematic look at research that can inform and guide those who are working to ensure that every child is in school and learning every day.

University human research ethics application procedures can be complicated and daunting, especially for international students unfamiliar with the process and the language. We conducted focus groups and interviews with four research higher degree and 21 Master’s coursework international students at an Australian university to gain their views on the human ethics application process. We found the most important influences on their experience were: the time it took to do an application; support from supervisors, peers and others; their own language skills; (...) and their lack of familiarity with research ethics procedures. To improve the experience of international students undertaking research involving human research ethics applications, we recommend universities provide guidance on institutional ethics review processes, concepts and terminology, with translations in a range of languages, together with guidance on how to conduct research ethically within and outside the students’ own countries. We also recommend curricula be developed to further students’ understanding of the importance of ethical research practice, and that these curricula be embedded in undergraduate and postgraduate degree programs and reflected in course learning outcomes.

ABSTRACT:Business networks, which include joint ventures, supply chains, industry and trade associations, industrial districts, and community business associations, are considered the signature organizational form of the global economy. However, little is known about how they affect the social performance of their members. We utilize institutional theory to develop the position that business social performance has collectivist roots that deserve at least as much scholarly attention as owner/manager characteristics and business attributes. Hypotheses are tested using multilevel analysis on data gathered from (...) 898 members of twenty-nine business associations. Support is provided for institutional theory’s explanation for business social performance. Members of business associations are likely to conform to the pattern of social performance prevailing in their association, but not necessarily to the articulated values of the association. The potential of business associations to influence members’ social performance should be considered by agencies that start and support them as mechanisms for regional and local economic development.

Next SectionThere has been considerable debate surrounding the ethics of sham-controlled trials of procedures and interventions. Critics argue that these trials are unethical because participants assigned to the control group have no prospect of benefit from the trial, yet they are exposed to all the risks of the sham intervention. However, the placebo effect associated with sham procedures can often be substantial and has been well documented in the scientific literature. We argue that, in light of the scientific evidence supporting (...) the benefits of sham interventions for pain and Parkinson's disease that stem from the placebo effect, these sham-controlled trials should be considered as offering potential direct benefit to participants. If scientific evidence demonstrates the positive effect of placebo from sham interventions on other conditions, sham-controlled trials of interventions for the treatment of these conditions should be considered to have prospects of benefit as well. This potential benefit should be taken into account by research ethics committees in risk-benefit analyses, and be included in informed consent documents. (shrink)

This mixed methods study examines how college students’ perceptions and experiences affect their understanding of academic integrity. Using qualitative and quantitative responses from the Personal and Social Responsibility Institutional Inventory, both quantitative and qualitative results demonstrate that while campuses may see a reduction in overall levels of cheating when punitive academic integrity policies are present, students may develop higher levels of personal and academic integrity through the use of more holistic and community-focused practices.

This article extends Lemieux’s concern for the interdisciplinary tension between philosophy and sociology to the intradisciplinary tension within psychology between approaches to the study of children focusing on universal principles and approaches adopting a contextual lens. This tension arises both in how development is defined and in the methods chosen for its study. This tension is exemplified in terms of the recent American preoccupation with the Word Gap (WG), a supposed difference of 30 million words heard by socioeconomically diverse children (...) by the age of 4 that is blamed for educational disparities throughout the school years. The article discusses the political implications of WG discourse as it gives rise to the erasure of language practices of diverse Americans and obscures the role that the educational system plays in fostering a ‘one-size-fits-all’ instructional model. The article concludes with a discussion of attempts to combat the deficit model that the WG discourse reproduces. (shrink)

Much research has examined the positive effects of legitimacy spillover. However, negative events may reduce the extent of legitimacy, which may in turn spillover to affect the legitimacy of important stakeholders including alliance partners. This study examines incidents of regulative legitimacy violation and focuses on the effect such incidents have on the alliance partners of the perpetrating organizations. We specifically examine three types of such violations—administrative law, criminal law, and civil law—to show that the loss of regulative legitimacy negatively influences (...) the stock market performance of alliance partners. More interestingly, not all corrective actions and repair efforts are equally impactful. We show that the effect of repair efforts by the perpetrating firm on the alliance partner differ depending on the nature of those violating incidents. (shrink)

Data are presented that focus on the nature and development of argumentative reasoning. In particular our study describes how support for or against an issue affects memory for critical parts of an argumentative interaction, judgments of argument goodness, and the content of the reasons given in support of one view versus another. Two other factors were examined: developmental differences in argumentation skill and the conditional nature of supporting one side of an argument across varying contexts. Our results show that even (...) seven year old children can recognize, identify, and use the basic components of an argument to provide evidence for and make judgements about their favored position. Moreover, if position support is held constant across all age groups of students, seven year old children were found to give reasons and explanations that were highly similar in content and principle to college students. The same similarities held across age with respect to biases in memory and judgements of argument goodness. The primary difference between children's and college students' argument behavior lay in the side of an argument the students chose to support. Seven year old children and some eleven yearold children supported positions that impute more value to friendship and social consequences than to the maintenance and advancement of individual rights, as specified in a contract agreement. The similarities and differences across development are discussed with respect to a theory of argumentation that speaks to the importance of understanding the nature of goal conflict and a theory of intentionality in predicting how arguments will be represented and resolved.

_Clinical Interaction and the Analysis of Meaning_ evinces a therapeutic vitality all too rare in works of theory. Rather than fleeing from the insights of other disciplines, Dorpat and Miller discover in recent research confirmation of the possibilities of psychoanalytic treatment. In Section I, "Critique of Classical Theory," Dorpat proposes a radical revision of the notion of primary process consonant with contemporary cognitive science. Such a revised conception not only enlarges our understanding of the analytic process; it also provides (...) analysis with a conceptual language that can articulate meaningful connections with a growing body of empirical research about the development and nature of human cognition. In Section II, "Interactional Theory," Miller reverses the direction of inquiry. He begins with the literature on cognitive development and functioning, and proceeds to mine it for concepts relevant to the clinical process. He shows how a revised understanding of the operation of cognition and affect can impart new meaning to basic clinical concepts such as resistance, transference, and level of psychopathology. In Section III, "Applications and Exemplifications," Dorpat concludes this exemplary collaboration by exploring select topics from the standpoint of his and Miller's new psychoanalytic theory. At the heart of the authors' endeavor it "meaning analysis," a concept that integrates an up-to-date model of human information processing with the traditional goals of psychoanalysis. The patient approaches the clinical encounter, they argue, with cognitive-affective schemas that are the accumulatice product of his life experience to date; the manifold meanings ascribed to the clinical interaction must be understood as the product of these schemas rather than as distortions deriving from unconscious, drive-related fantasies. The therapist's goal is to make the patient's meaning-making conscious and thus available for introspection. (shrink)

In this paper, we move toward offering psychological benchmarks to measure success in building increasingly humanlike robots. By psychological benchmarks we mean categories of interaction that capture conceptually fundamental aspects of human life, specified abstractly enough to resist their identity as a mere psychological instrument, but capable of being translated into testable empirical propositions. Nine possible benchmarks are considered: autonomy, imitation, intrinsic moral value, moral accountability, privacy, reciprocity, conventionality, creativity, and authenticity of relation. Finally, we discuss how getting the right (...) group of benchmarks in human–robot interaction will, in future years, help inform on the foundational question of what constitutes essential features of being human.

BackgroundIn the Canadian Alliance for Healthy Hearts and Minds (CAHHM) cohort, participants underwent magnetic resonance imaging (MRI) of the brain, heart, and abdomen, that generated incidental findings (IFs). The approach to managing these unexpected results remain a complex issue. Our objectives were to describe the CAHHM policy for the management of IFs, to understand the impact of disclosing IFs to healthy research participants, and to reflect on the ethical obligations of researchers in future MRI studies.MethodsBetween 2013 and 2019, 8252 participants (...) (mean age 58 ± 9 years, 54% women) were recruited with a follow-up questionnaire administered to 909 participants (40% response rate) at 1-year. The CAHHM policy followed a restricted approach, whereby routine feedback on IFs was not provided. Only IFs of severe structural abnormalities were reported.ResultsSevere structural abnormalities occurred in 8.3% (95% confidence interval 7.7–8.9%) of participants, with the highest proportions found in the brain (4.2%) and abdomen (3.1%). The majority of participants (97%) informed of an IF reported no change in quality of life, with 3% of participants reporting that the knowledge of an IF negatively impacted their quality of life. Furthermore, 50% reported increased stress in learning about an IF, and in 95%, the discovery of an IF did not adversely impact his/her life insurance policy. Most participants (90%) would enrol in the study again and perceived the MRI scan to be beneficial, regardless of whether they were informed of IFs. While the implications of a restricted approach to IF management was perceived to be mostly positive, a degree of diagnostic misconception was present amongst participants, indicating the importance of a more thorough consent process to support participant autonomy.ConclusionThe management of IFs from research MRI scans remain a challenging issue, as participants may experience stress and a reduced quality of life when IFs are disclosed. The restricted approach to IF management in CAHHM demonstrated a fair fulfillment of the overarching ethical principles of respect for autonomy, concern for wellbeing, and justice. The approach outlined in the CAHHM policy may serve as a framework for future research studies.Clinical trial registrationhttps://clinicaltrials.gov/ct2/show/nct02220582. (shrink)

The education of students and professionals in business ethics is an increasingly important goal on the agenda of business schools and corporations. The present study provides a meta-analysis of 25 previously conducted business ethics instructional programs. The role of criteria, study design, participant characteristics, quality of instruction, instructional content, instructional program characteristics, and characteristics of instructional methods as moderators of the effectiveness of business ethics instruction were examined. Overall, results indicate that business ethics instructional programs have a minimal␣impact on increasing (...) outcomes related to ethical perceptions, behavior, or awareness. However, specific criteria, content, and methodological moderators of effectiveness shed light on potential recommendations for␣improving business ethics instruction. Implications for␣future research and practice in business ethics are discussed. (shrink)

In his epistemological system Mead begins with that which the chief philosophers rejected, the novel or exceptional, and makes it central. It is central in a respect which should be carefully explained. The novel or emergent is that with reference to which a present is defined, and a present is the seat of reality. In saying this Mead does not mean that “the past” and “the future” are meaningless terms. Nor does he reduce them to a present. Rather he holds (...) that neither the past nor the future exists. In fact, they are meaningful only in relation to a present and the various pasts and futures referred to in our statement of causal conditions and predictions belong to a present, which is their seat. Mead escapes the metaphysical problem as to whether the past or the future has some sort of being even now. Certainly in so far as he has a metaphysics at all it derives from his epistemology which is primary and represents a pioneering attempt to develop a theory of knowledge answering to experimental science. Consciously or unconsciously most contemporary scientists are still under the influence of bygone epistemological and metaphysical doctrines in their explicit statements of what constitutes reality and knowing. Yet in so far as they are successful in practice obviously they are free from the blind alleys and dead ends which these older theories lead to logically. However no one, not even the philosopher, has been able to formulate a consistent set of epistemological principles from which experimental scientific procedure follows logically. One thing, Mead contends, has been wholly neglected. It is the emergent. (shrink)

Objectives—To study the attitudes of health care staff in four postcommunist countries towards taking gifts from their clients—and their confessed experience of actually taking such gifts.Design—Survey questionnaire administered to officials including health care staff, supplemented by focus-group discussions with the general public.Setting – Ukraine, Bulgaria, Slovakia and the Czech Republic.Participants—A quota sample of 1,307 officials including 292 health care staff, supplemented by stratified national random samples of 4,778 ordinary members of the public and in-depth interviews or focus-group discussions involving another (...) 323.Main measurements—Explicit justifications and willingness to accept offers, reported frequency of offers, and personal confessions to accepting “money and expensive presents” as well as smaller gifts.Results—Health care staff were far more inclined than the average official or public servant to accept “money or an expensive present” if offered, far more inclined to justify asking clients for “extra payments”, and far more inclined to confess that they had actually taken gifts from clients recently. Judged by their own confessions, hospital doctors were only rivalled by traffic police and customs officials for taking money or expensive gifts from their clients.Conclusions—Poor pay does not explain why doctors so often took large gifts from their clients. Moral self justification, opportunity, and bargaining power are much more effective explanations. (shrink)

Examination of the target article for its relevance to the analysis of private behavior leads to three concerns: the absence of a new methodology for studying private behavior, the undisclosed possibility of interactions, and insufficient attention to the social context of idea generation. Regardless of these concerns, a larger issue remains: Can a science of n = 1 be credible?

In linguistic terms, a quantifier is an item that appears with a noun to specify the number or amount of referents indicated by the noun. In English, various kinds of quantification are lexically differentiated—universal quantification, distributive quantification, and universal-distributive. In Greek, however, quantification is conveyed syntactically using primarily one lexical item, namely πᾶς. In this article, we examine the syntactic patterns of πᾶς as a quantifier from a linguistic point of view with attention to the determination of the noun, the (...) number of the noun and the phrasal word order. We also examine the phenomenon of ‘floating’ quantification in which the quantifier moves to a new position in the noun phrase. Finally, we compare the patterns found in New Testament Greek with those of the quantifier כל in the Hebrew Bible in order to determine the extent and type of Semitic interference with respect to quantification in New Testament Greek grammar.Contribution: The syntactic patterns of πᾶς as a quantifier are identified and the semantic import of each pattern is described. The relationship of πᾶς to the quantifier כל in the Hebrew Bible shows evidence of Semitic interference in New Testament Greek grammar. (shrink)

Differences across fields and experience levels are frequently considered in discussions of ethical decision making and ethical behavior. In the present study, doctoral students in the health, biological, and social sciences completed measures of ethical decision making. The effects of field and level of experience with respect to ethical decision making, metacognitive reasoning strategies, social-behavioral responses, and exposure to unethical events were examined. Social and biological scientists performed better than health scientists with respect to ethical decision making. Furthermore, the ethical (...) decision making of health science students decreased as experience increased. Moreover, these effects appeared to be linked to the specific strategies underlying participants' ethical decision making. The implications of these findings for ethical decision making are discussed. (shrink)
