The Impact of Disrespect on Prisoners’ Aggression: Outcomes of Experimentally Inducing Violence Supportive Cognitions

Self-report research suggests that much violence is triggered by perceived insults and disrespect. This may be particularly true in the context of a prison or another environment of acute deprivation, whereby individuals have little other recourse to means of reputation enhancement. This paper presents the findings of two studies conducted with prisoner volunteers inside a Category C (minimum security) prison in England. In the first study, the authors randomly assigned a sample of 89 prisoners to one of two conditions: the experimental group were asked to discuss times they have been disrespected by authority figures inside and outside the prison; the control group were asked more neutral questions. Both groups then completed several measures of cognitive beliefs, distortions, and hostile attribution biases. None of the measures differed across the two groups except the measure of excuse and justification acceptance. Controlling for other factors, the experimental group endorsed these rationalisations at a significantly higher rate than the control group. This finding suggests that raising the salience of disrespect - reminding prisoners of times they have been made to feel unworthy of consideration - may raise the risk that prisoners will engage in violence by providing prisoners with justifications or excuses for actions they might not otherwise endorse. These findings received some additional validation in the second study, a qualitative analysis of offender accounts of violence and aggression within the prison. Implications for reducing violence within prisons are discussed.

The Philosophy and Practice of Interpretivist Research in Entrepreneurship Quality, Validation, and Trust

Knowledge production in entrepreneurship requires inclusivity as well as diversity and pluralism in research perspectives and approaches. In this article, the authors address concerns about interpretivist research regarding validity, reliability, objectivity, generalizability, and communicability of results that militate against its more widespread acceptance. Following the nonfoundationalist argument that all observation is theory-laden, context specific, and that there are no external criteria against which to assess research design and execution and the data produced, the authors propose that quality must be internalized within the underlying research philosophy rather than something to be tested upon completion. This requires a shift from the notion of validity as an outcome to validation as a process. To elucidate this, they provide a guiding framework and present a case illustration that will assist an interpretivist entrepreneurship researcher to establish and demonstrate the quality of their work.

Steady-State and Transient Performance of Biodiesel-Fueled Compression-Ignition-Based Electrical Generation

This paper investigates the performance characteristics of rapeseed methyl ester, EN 14214 biodiesel, when used for electrical generation in compression ignition engines. The work was inspired by the need to replace fossil diesel fuel with a sustainable low carbon alternative while maintaining generator performance, power quality, and compliance with ISO 8528-5. A 50-kVA Perkins diesel engine generator was used to assess the impact of biodiesel with particular regard to gen-set fuel consumption, load acceptance, and associated standards. Tests were performed on the diesel gen-set for islanded and grid-connected modes of operation, hence both steady-state and transient performance were fully explored. Performance comparisons were made with conventional fossil diesel fuel, revealing minimal technical barriers for electrical generation from this sustainable, carbon benign fuel. Recommendations for improved transient performance are proposed and validated through tests.

Is low self-esteem an inevitable consequence of stigma? An example from women with chronic mental health problems

It is often assumed that membership in a stigmatized group has negative consequences for the self-concept. However, this relationship is neither straightforward nor inevitable, and there is evidence suggesting that negative consequences may not necessarily occur (Psychol. Rev. 96(4) (1989) 608). This paper argues that the relationship has not been sufficiently theorized, and that a more detailed analysis is called for in order to understand the relationship between stigma and the self. The paper presents a critical examination of modified labeling theory (Am. Sociol. Rev. 52 (1987) 96), with examples from a study examining perceptions of stigma and their relationship to self-evaluation in women with chronic mental health problems. Open-ended interviews and qualitative analyses were used in preference to global measures of self-esteem. It was found that although the women were aware of society's unfavorable representations of mental illness, and the effects this had on their lives, they did not accept these representations as valid and therefore rejected them as applicable to the self. The participants did not deny their mental health problems, but their acceptance of labels was critical and pragmatic. Labels were rejected when they were perceived as carrying an unrealistic and negative stereotype, or when the women felt that their symptoms did not fit with the diagnostic criteria. The research illustrates the importance of considering people's subjective understandings of stigmatized conditions and societal reactions in order to understand the relation between stigma and the self.

The effect of teachers trained in a fundamental movement skills programme on children’s self-perceptions and motor competence

Perceived and actual motor competence are hypothesized to have potential links to children and young people’s physical activity (PA) levels with a potential consequential link to long-term health. In this cross-sectional study, Harter’s (1985, Manual for the Self-perception Profile for Children. Denver, CO: University of Denver) Competency Motivation-based framework was used to explore whether a group of children taught, during curriculum time, by teachers trained in the Fundamental Movement Skills (FMS) programme, scored higher on self-perception and on core motor competencies when compared to children whose teachers had not been so trained. One hundred and seventy seven children aged 7–8 years participated in the study. One hundred and seven were taught by FMS-trained teachers (FMS) and the remaining 70 were taught by teachers not trained in the programme (non-FMS). The Harter Self-Perception Profile for Children assessed athletic competence, scholastic competence, global self-worth and social acceptance. Three core components of motor competence (body management, object control and locomotor skills) were assessed via child observation. The FMS group scored higher on all the self-perception domains (p < 0.05). Statistically significant differences were found between the schools on all of the motor tasks (p < 0.05). The relationships between motor performance and self-perception were generally weak and non-significant. Future research in schools and with teachers should explore the FMS programme’s effect on children’s motor competence via a longitudinal approach.

Climate change, Hans Jonas and indirect investors

This article considers how corporate behaviour in relation to climate change might be reconfigured and the role that indirect investors might play in this reconfiguring. The article suggests that the consequences of climate change are serious enough that indirect investors might be prevailed upon, using a model of behaviour suggested by the work of Hans Jonas, to pressure institutional investors into demanding changes in corporate policy towards climate change. Jonas' work represents a plea for the recognition and acceptance of responsibility in the face of nature's vulnerability and humanity's power over technology. The article suggests that this ethic can be operationalised in relation to corporate governance by building on the changes in the pattern of investment holdings that have taken place in large public companies in the preceding two decades or so. The idea is to appeal to individuals who may perceive themselves as currently being outsiders – or at least only distant stakeholders in relation to the corporation – to realise the responsibility vested in them as beneficiaries through their interest in pension funds, life assurance policies, annuities and other arm's-length financial arrangements with corporations. The hope is that these individuals may, through the influence of a model of responsibility, become active investors and beneficiaries interested in corporate practices that impact on climate change and, encourage others to do likewise.

Long Term Use of HU210 Adversely Affects Spermatogenesis in Rats by modulating the Endocannabinoid System

Recent societal acceptance of cannabinoids as recreational and therapeutic drugs has posed a potential hazard to male reproductive health. Mammals have a highly sophisticated endogenous cannabinoid (ECS) system that regulates male (and female) reproduction and exo-cannabinoids may influence it adversely. Therefore it is imperative to determine their effects on male reproduction so that men can make informed choices as to their use. Here, an animal model was used to administer HU210, a synthetic analogue of ?9-tetrahydrocannabinol (THC) and potent cannabinoid receptor (CB) agonist to determine its effects on reproductive organ weights, spermatogenesis, testicular histology and sperm motility. Its effects on the physiological endocannabinoid system were also investigated. Spermatogenesis was markedly impaired with reductions in total sperm count after 2 weeks of exposure. Spermatogenic efficiency was depleted, and Sertoli cell number decreased as exposure time increased with seminiferous tubules showing germ cell depletion developing into atrophy in some cases. Sperm motility was also adversely affected with marked reductions from 2 weeks on. HU210 also acted on the sperm’s endocannabinoid system. Long term use of exo-cannabinoids has adverse effects on both spermatogenesis and sperm function. These findings highlight the urgent need for studies evaluating the fertility potential of male recreational drug users.

A comparative study of three techniques for determining photocatalytic activity

Quantitative measurement of the activity of photoactive films is an area of importance. The establishment of tests for standardisation of performance is important for efficient research but also a major milestone in achieving technology acceptance. In this paper, we compare three different techniques across a range of film samples from various sources. Furthermore, we demonstrate the potential of the dye-based approach as a quick and simple test. A series of photoactive film samples are compared for measured activity against each test. The test is shown to be capable of reproducible and quantitative activity results. The test has potential for use

Detection of 3-amino-2-oxazolidinone (AOZ), a tissue-bound metabolite of the nitrofuran furazolidone, in prawn tissue by enzyme immunoassay

Furazolidone, a nitrofuran antibiotic, is banned from use in food animal production within the European Union. Increasingly, compliance with this ban is monitored by use of analytical methods to detect a stable tissue-bound metabolite, 3-amino-2-oxazolidinone (AOZ). Widespread use of furazolidone in poultry and prawns imported into Europe highlighted the urgent need for development of nitrofuran immunoassay screening tests. The first enzyme-linked immunoabsorbant assay for detection of AOZ residues in prawns (shrimps) is now described. Prawn samples were derivatized with o-nitrobenzaldehyde, extracted into ethyl acetate, washed with hexane and applied to a competitive enzyme immunoassay based on a rabbit polyclonal antiserum. Assay limit of detection (LOD) (mean+3 s) calculated from the analysis of 20 known negative cold and warm water prawn samples was 0.1 mug kg(-1). Intra- and interassay relative standard deviations were determined as 18.8 and 38.2%, respectively, using a negative prawn fortified at 0.7 mug kg(-1). The detection capability (CCbeta), defined as the concentration of AOZ at which 20 different fortified samples yielded results above the LOD, was achieved at fortification between 0.4 and 0.7 mug kg(-1). Incurred prawn samples (n=8) confirmed by liquid chromatography coupled with tandem mass spectrometry detection to contain AOZ concentrations between 0.4 and 12.7 mug kg(-1) were all screened positive by this enzyme-linked immunoabsorbant assay. Further data are presented and discussed with regard to calculating assay LOD based on accepting a 5% false-positive rate with representative negative prawn samples. Such an acceptance improves the sensitivity of an ELISA and in this case permitted an LOD of 0.05 mug kg(-1) and a CCbeta of below 0.4 mug kg(-1).

Towards Charity Accountability: Narrowing the gap between provision and needs?

Although charities currently play a rich and varied role in modern society, their continued success is dependent upon the public's trust. With respect to charity accountability, two key questions emerge: to whom is a charity accountable; and what form should that account take? Despite the widespread acceptance that charities should discharge accountability, there is limited knowledge of the relative importance of different stakeholder groups and whether the information currently being disclosed meets their needs. Using extensive document analysis and a survey of stakeholders, this research explores these issues in the context of the top 100 UK fundraising charities. Furthermore, it compares the results with much earlier research to identify changes over time.

Measurement of absolute charge-exchange cross sections for He2+ collisions with He and H-2

Reported are total, absolute charge-exchange cross sections for collisions of 3He(2+) ions with He and H-2. Measurements are reported at fixed energies between 0.33 and 4.67 keV/amu. Both the present results and earlier results of others are analyzed in terms of available experimental small-angle differential cross sections as a function of collision energy, and hence the geometry of the exit aperture of the gas-collision cells used by the various experimental groups. In addition, the effective length of gas-collision cells is studied using fluid dynamic and molecular flow simulations to address the density patterns near the cell entrance and exit apertures. When small acceptance-angle corrections were applied, the results of present and previous measurements for the single electron capture in these systems were brought into good accord in the relevant energy ranges. Taken in their entirety, the present data for 3He(2+) with He and H-2 lend themselves to new theoretical calculations of the multichannel charge-exchange cross sections.

Monoclonal antibody-based ELISA for the quantification of nitrofuran metabolite 3-amino-2-oxazolidinone in tissues using a simplified sample preparation

<p>A sensitive and specific monoclonal ELISA for the determination of tissue bound furazolidone metabolite 3-amino-2-oxazolidinone (AOZ) is described. The procedure enables the detection of AOZ in matrix supernatant after homogenisation, protease treatment, acid hydrolysis and derivatisation of AOZ released from the tissue by o-nitrobenzaldehyde. The formed p-nitrophenyl 3-amino-2-oxazolidinone (NPAOZ) is determined by ELISA calibrated with matrix-matched standards in the concentration range of 0.05-5.0 mu g l(-1). The assay was validated according to criteria set down by Commission Decision 2002/657/EC for the performance and validation of analytical methods for chemical residues. Detection capability, set on the basis of acceptance of no false negative results, was 0.4 mu g kg(-1) for shrimp, poultry, beef and pork muscle. This sensitivity approaches the established confirmatory LC-MS/MS able to quantify tissue-bound AOZ at levels as low as 0.3 mu g kg(-1). An excellent correlation of results obtained by ELISA and LC/MS-MS within the concentration range 0-32.1 mu g kg(-1) was found in the naturally contaminated shrimp samples (r = 0.999, n = 8). A similar con-elation was found for the incurred poultry samples within the concentration range of 0-10.5 mu g kg(-1) (r = 0.99, n = 8). (c) 2005 Elsevier B.V All rights reserved.</p>

A mirage of genes

This paper examines the structure of popular conceptions of the new genetics, and assesses why genetics has been so readily accepted in medicine and in the public discourse. Adapting Rene Dubos' classic analysis, Mirage of Health, we examine the new genetics by comparing it to Dubos' analysis of the structure and limits of germ theory. Germ theory focuses on the internal rather than the external environment, emphasises a doctrine of specific aetiology, and adopts the metaphor of the body as a machine. The germ theory model narrowed our vision about disease aetiology, proved misleading in some cases, yet remained the basis for clinical medical models of disease. In recent years, genetics has moved to the cutting edge of medical research and thinking about disease and behaviour. The structure of popular conceptions of the new genetics shows remarkable parallels with germ theory. This has eased the acceptance of genetics but simultaneously raises questions about these genetic explanations. An appearance and allure of specificity privileges genetic explanations in the public discourse; on examination, this specificity may prove to be a mirage.

Compliance with recommendations in a geriatric outreach assessment service

Objectives: to measure the extent to which the recommendations of a geriatric outreach assessment service were being followed, and to determine what patient-related factors were associated with compliance with assessment recommendations. Methods: eighty-one eligible patients or caregivers who had an assessment in a geriatric outreach service participated in a telephone interview. The interview focused on the use of health services and compliance with assessment recomendations. Patient-related variables obtained from charts included demographics, caregiver support and stability, health status and assessment recommendations. Results: overall compliance with recommendations from the geriatric outreach assessment service was 65%. Patients were less likely comply fully with recommendations if they had a high number of recommendations [odds ratio (OR) = 0.23; 95% confidence interval (CI) = 0.12-0.46; P = 0.0001], inadequate caregiver support (OR) = 0.212; 95% CI = 0.04 to 1.02; P = 0.0523), or the ability to transfer themselves independently (OR = 0.12; 95% CI = 0.02-0.63; P = 0.0124). They were more likely to have full compliance if they had normal vision (OR = 6.67; 95% CI = 1.22- 36.46; P = 0.0284). Conclusion: it is important to focus on key issues when developing service recommendations and on the role of the informal caregiver in facilitating compliance with them. Good communication between the patient or caregiver and the family physician and geriatric services can help to identify strategies which might improve acceptance of recommendations.

I can't get a breath: experiences of living with advanced chronic obstructive pulmonary disease

This study aims to explore the potential for palliative care among people living with advanced chronic obstructive pulmonary disease (COPD). Individual semi-structured interviews (n=13) were conducted with people who had a diagnosis of advanced COPD and were on optimal tolerated drug therapy, with their breathing volume (forced expiratory volume at less than 30%) or were on long-term oxygen therapy or non-invasion ventilation. Participants raised concerns about the uncertain trajectory of the illness and reported unmet palliative care needs with poor access to palliative care services. For most people, palliative care was associated with end of life; therefore, they were unwilling to discuss the issue. There was a wide acceptance that, medically, nothing more could be done. Findings also suggest that patients had unmet palliative care needs, requiring information and support. The research suggests the need for palliative care to be extended to all (regardless of diagnosis), with packages of care developed to target specific needs.
