Structural models of antisocial behavior and during‐treatment performance for probationers in a substance abuse treatment program

Prior research has linked substance abuse and antisocial behavior. This study uses structural models to examine developmental stages of antisocial behavior and their relation to during‐treatment performance of probationers in a 4‐month inpatient program. Separate childhood and adulthood antisocial functioning components were identified, and each predicted during‐treatment psychological functioning and program perceptions. Specifically, adulthood hostility predicted psychological functioning, and adulthood risk‐taking predicted program perceptions; the effect of childhood antisocial behavior was completely mediated by adulthood functioning.     

Active Vibration Control of a Single Mass Rotor on Flexible Supports

This paper considers vibration control of a single mass flexible rotor on damped flexible supports with active feedback control. Both proportional and derivative feedback control are utilized. Free vibrations and unbalance response of the rotor-control system are determined. The effect of proportional control is to increase the critical speed of rotating machinery while the effect of derivative control is to reduce the amplitude of vibration. Generally larger ratios of support stiffness to shaft stiffness require larger values of control parameters to produce given amplitudes of vibration.     

Technological innovation in developing countries: a review of the literature

The recent literature on the role of science and technology in developing countries is reviewed in order to assess the extent of our current knowledge concerning the sociological factors affecting the development of indigenous scientific and technological innovations. Existing studies provide some preliminary evidence in favor of the hypothesis that inadequate linkages between institutions in the various sectors of developing societies inhibit the development and utilization of indigenous technological innovations.In general, relationships between government research organizations and the potential users of their technological innovations are absent or unsatisfactory. Academic research tends to be oriented toward the interests of the international scientific community. The substantial literature on the problems of indigenous technological transfer in India suggests that inadequate coordination between different sectors of that society is in part responsible for its failure to develop its potential for technological innovation.Recent attempts to stimulate the production and diffusion of indigenous technology in developing countries by creating new types of research institutes in the university and coordinating agencies in the government are discussed. Systematic evaluations of these programs are lacking, but coordinating agencies have often performed poorly because of insufficient power to influence the policies of other organizations.A sociological approach based on interorganizational analysis is suggested for future studies of this problem. This literature identifies the optimal characteristics of coordinating organizations at the government level and of research utilizations systems which link research organizations to their clients at the local level.A bibliography comprising 102 references classified by region is included.     

Pedagogical Content Knowledge of Inquiry： An Instrument to Assess It and Its Application to High School In-Service Science Teachers

It is argued that the lack of consensus on what constitutes an inquiry-based approach makes the generalization about it difficult, because the concept is relatively unspecific and vague. This problem can partially be solved by constructing a set of activities promoted by inquiry, thus defining the inquiry objectives for classroom and laboratory teaching. Five high school and college Mexican teachers＇ PICK （pedagogical inquiry/content knowledge） was documented and assessed by means of Loughran, Mulhall and Berry＇s （2004） l-CoRe （inquiry content representation） developed by the authors through a proposal of a set of seven inquiry activities. They were also interviewed to construct the professional and pedagogical experience repertoires, a second tool by Loughran et al. （2004） to document PICK. It was observed that all teachers interviewed have used inquiry to modify their students＇ way of thinking, mainly through question posing. Some of them employed research as their main tool to promote scientific inquiry but others mentioned the lack of time to do it. It is interesting to notice that in spite of the fact that inquiry is out of the curriculum in M6xico, the teachers make use of it to improve their teaching practice. According to their answers, their actions in the classroom or the lab were classified within the three general approaches expressed by Lederman （2004）： implicit, historical and explicit. It is concluded that a given teacher cannot be classified exclusively in one of them, because in his/her activities one general approach overlaps the others. The authors conclude that Lederman＇s classification has to be taken into account as an orientation to characterize a given activity of one teacher, even though the same teacher may use another activity characterized by other general approach. That is, Lederman＇s classification applies to characterize activities, not persons     

Medical student attitudes to the autopsy and its utility in medical education: A brief qualitative study at one UK medical school

Attending postmortems enables students to learn anatomy and pathology within a clinical context, provides insights into effects of treatment and introduces the reality that patients die. Rates of clinical autopsies have declined and medical schools have cut obligatory autopsy sessions from their curricula making it difficult to assess medical student perceptions of, and attitudes towards, the educational value of autopsy. Our aim was to investigate these perceptions by designing a brief qualitative study comprising nominal technique and focus group discussions with Cambridge Graduate Course students, all of whom had attended autopsies. Three general themes emerged from the focus group discussions: the value of autopsy as a teaching tool and ways the experience could be improved, the initial impact of the mortuary and the autopsy itself, and the “emerging patient”—an emotional continuum running from cadaver to autopsy subject and living patient. Educational benefits of autopsy‐based teaching included greater understanding of anatomy and physiology, greater appreciation of the role of other health care professionals and an enhanced appreciation of psycho‐social aspects of medical practice. Students suggested improvements for ameliorating the difficult emotional consequences of attendance. We conclude that autopsy‐based teaching represents a low‐cost teaching technique which is highly valued by students and has application to many diverse medical specialties and skills. However, careful preparation and organization of sessions is required to maximize potential educational benefits and reduce any negative emotional impact.

Methodological Issues in Ethnic and Racial Identity Research With Ethnic Minority Populations: Theoretical Precision,Measurement Issues,and Research Designs

This article takes stock of research methods employed in the study of racial and ethnic identity with ethnic minority populations. The article is presented in three parts. The first section reviews theories, conceptualizations, and measurement of ethnic and racial identity (ERI) development. The second section reviews theories, conceptualizations, and measurement of ERI content. The final section reviews key methodological and analytic principles that are important to consider for both ERI development and content. The article concludes with suggestions for future research addressing key methodological limitations when studying ERI.     

A roadmap for forming successful interdisciplinary education research collaborations: a reflective approach

Current literature about interdisciplinary education research is focused on three points: conceptual definitions of interdisciplinarity, the need for interdisciplinary research to tackle the advent of problem-based research and the positive curriculum outcomes to be gained from interdisciplinary research. While this research is important, it does not always include an account of the often complex and politicised interactions that might affect the outcomes of interdisciplinary research groups. This paper provides one possible ‘roadmap’ for successful interdisciplinary collaboration. It is based on a reflective case study of the authors’ own formation of an interdisciplinary research group and the practical resolutions to both the theoretical and the practical issues involved in achieving interdisciplinarity in education research.     

Increased plasma zonulin in patients with sepsis

Introduction:

Zonulin is a eukaryotic protein structurally similar to Vibrio cholerae’s zonula occludens toxin. It plays an important role in the opening of small intestine tight junctions. The loss of gut wall integrity during sepsis might be pivotal and has been described in various experimental as well as human studies. Increased levels of zonulin could be demonstrated in diseases associated with increased intestinal inflammation, such as celiac disease and type 1 diabetes. We therefore investigated the role of plasma levels of zonulin in patients with sepsis as a non-invasive marker of gut wall integrity.

Materials and methods:

Plasma level of zonulin was measured in 25 patients with sepsis, severe sepsis or septic shock according to ACCP/SCCM criteria at the first day of diagnosed sepsis. 18 non-septic post-surgical ICU-patients and 20 healthy volunteers served as control. Plasma levels were determined by using commercially available ELISA kit. Data are given as median and interquartile range (IQR).

Results:

Significantly higher plasma concentration of zonulin were found in the sepsis group: 6.61 ng/mL (IQR 3.51–9.46), as compared to the to the post-surgical control group: 3.40 ng/mL (IQR 2.14–5.70) (P = 0.025), as well as to the healthy group: 3.55 ng/mL (IQR 3.14–4.14) (P = 0.008).

Conclusion:

We were able demonstrate elevated levels of plasma zonulin, a potential marker of intestinal permeability in septic patients. Increased zonulin may serve as an additional mechanism for the observed increased intestinal permeability during sepsis and SIRS.     

Personal and situational factors influencing coaches’ perceptions ofstress

Abstract

Coaching has been recognised as a demanding occupation, associated with a range of stressors. The extent to which coaches perceive stress is likely to be influenced by various personal and situational factors. The purpose of this study was to identify coaches' levels of perceived stress and examine the personal and situational factors that may influence coaches' perceptions of stress. In total, 502 coaches working with university, college, Canada Games, and/or nationally identified athletes completed this study. Coaches completed an online survey, which included questions regarding demographics, work/job-related considerations, and aspects relating to their contract. Coaches also completed the Perceived Stress Scale (Cohen, Kamarck, & Mermelstein, 1983 Cohen, S., Kamarck, T. and Mermelstein, R. 1983. A global measure of perceived stress. Journal of Health and Social Behavior, 24: 385–396. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). Overall coaches indicated slightly below average levels of perceived stress (M = 15.13 out of 40) compared with norm-values (Cohen & Janicki-Deverts, 2012 Cohen, S. and Janicki-Deverts, D. 2012. Who's stressed? Distributions of psychological stress in the United States in probability samples from 1983, 2006, and 2009. Journal of Applied Social Psychology, 42: 1320–1334. [Crossref], [Web of Science ®] , [Google Scholar]). Demographic factors, job-related characteristics, and certain aspects of their contract were associated with coaches' perceptions of stress. In particular, unclear expectations, long-working hours (>40), lack of agreed evaluation criteria, higher salaries, and a lack of social support were related to higher perceptions of stress. As such, the findings of the current study indicate that a reduction in perceived stress is likely to be achieved through a multifaceted approach that addresses multiple factors associated with coaching.     

Distributed leadership of school curriculum change: an integrative approach

Since its inception in 1999, the distributed leadership framework of Spillane, Halverson, and Diamond [2004. “Towards a Theory of Leadership Practice: A Distributed Perspective.” Journal of Curriculum Studies 36 (1): 3–34. doi:10.1080/0022027032000106726] has supported research into leadership and change in schools. Whilst the conceptual integrity of the framework is sound, research based upon its premises has attracted some criticism. The research has had a narrowed focus which has not generally reflected the inseparability of the elements of the framework and the situation within which leadership is enacted. In addition, it often fails to account for the complexity of critical elements of the environment such as micropolitics. This position paper proposes a reconfiguration of the distributed leadership framework as a research framework in response to this critique. The paper asserts that this new perspective that is presented is able to respond to the critique through an integrated approach that encompasses situation, social distribution and task enactment and which supports an integrated approach to research methodology. This adapted framework has the potential to more fully support research design that is actuality holistic and embedded in the context.
