Role ambiguity, role conflict and job satisfaction of Clark County School District counselors

Counselors in the Clark County School District, Las Vegas, Nevada were chosen for a study of the relationship of job satisfaction, role ambiguity and role conflict. A written survey consisting of the Teacher Job Satisfaction Questionnaire (Lester, 1984) and the Role Questionnaire (Rizzo et al., 1970) was conducted of selected full-time K-12 counselors in an attempt to assess the effects of role ambiguity and role conflict in six selected areas of job satisfaction: work itself, working conditions, recognition, responsibility, supervision and colleagues; The results showed that as the job satisfaction of the counselors increased, the amount of role ambiguity and role conflict decreased. Two areas of job satisfaction--colleagues and responsibility--appeared to have no relationship with either role ambiguity or role conflict. General comments from the counselors indicated concern in the areas of: counseling budget, double school assignments, lack of clear understanding of the counselor\u27s role and counselors being given tasks that could be performed by clerical staff

Neurocognitive and mental health outcomes in children with tungiasis: a cross-sectional study in rural Kenya and Uganda

Background Tungiasis, a neglected tropical parasitosis, disproportionately affects children. Few empirical studies have reported neurocognitive and mental health outcomes of children with ectoparasitic skin diseases like tungiasis. Pathophysiology of tungiasis suggests it could detrimentally affect cognition and behaviour. This study pioneered the investigation of neurocognitive and mental health outcomes in children with tungiasis. Methods This was a multi-site cross-sectional study including 454 quasi-randomly sampled school-children aged 8–14 from 48 randomly selected schools in two counties in Kenya and a district in Uganda. The participants were stratified into infected and uninfected based on the presence of tungiasis. The infected were further classified into mild and severe infection groups based on the intensity of the infection. Adapted, validated, and standardized measures of cognition and mental health such as Raven Matrices and Child Behaviour Checklist were used to collect data. Statistical tests including a multilevel, generalized mixed-effects linear models with family link set to identity were used to compare the scores of uninfected and infected children and to identify other potential risk factors for neurocognitive and behavioural outcomes. Results When adjusted for covariates, mild infection was associated with lower scores in literacy [adjusted β(aβ) = − 8.9; 95% confidence interval (CI) − 17.2, − 0.6], language (aβ = − 1.7; 95% CI − 3.2, − 0.3), cognitive flexibility (aβ = − 6.1; 95% CI − 10.4, − 1.7) and working memory (aβ = − 0.3; 95% CI − 0.6, − 0.1). Severe infection was associated with lower scores in literacy (aβ = − 11.0; 95% CI − 19.3, − 2.8), response inhibition, (aβ = − 2.2; 95% CI − 4.2, − 0.2), fine motor control (aβ = − 0.7; 95% CI − 1.1, − 0.4) and numeracy (aβ = − 3; 95% CI − 5.5, − 0.4). Conclusions This study provides first evidence that tungiasis is associated with poor neurocognitive functioning in children. Since tungiasis is a chronic disease with frequent reinfections, such negative effects may potentially impair their development and life achievements

Amygdala volume and hypothalamic-pituitary-adrenal axis reactivity to social stress

The amygdala plays a central role in emotional processing and has an activating influence on the hypothalamic-pituitary-adrenal (HPA) axis. Structural changes in the amygdala have been associated with early adversity and, in principle, may contribute to the later emergence of emotional pathologies by influencing the way that the brain responds to stress provocation. The present study examined the relationship between amygdala volumes and cortisol secretion in response to a social stressor among young adults who were or were not exposed to maternal postnatal depression (PND) early in development (referred to as PND offspring and controls, respectively). Hierarchical Linear Modelling (HLM) revealed that, on a sample-wide level, there was no evidence of a relationship between total amygdala volume, or the volume of the right or left hemisphere amygdala taken separately, and cortisol reactivity. Unexpectedly, for PND offspring, larger right hemisphere amygdala volume was associated with lower cortisol reactivity in response to stress, an effect that was not apparent in control offspring. We conclude that the relationship between amygdala volumes and stress reactivity may not be as clear as previous models suggested

The EGFR/ErbB inhibitor neratinib modifies the neutrophil phosphoproteome and promotes apoptosis and clearance by airway macrophages

Dysregulated neutrophilic inflammation can be highly destructive in chronic inflammatory diseases due to prolonged neutrophil lifespan and continual release of histotoxic mediators in inflamed tissues. Therapeutic induction of neutrophil apoptosis, an immunologically silent form of cell death, may be beneficial in these diseases, provided that the apoptotic neutrophils are efficiently cleared from the tissue. Previous research in our group identified ErbB inhibitors as able to induce neutrophil apoptosis and reduce neutrophilic inflammation both in vitro and in vivo. Here, we extend that work using a clinical ErbB inhibitor, neratinib, which has the potential to be repurposed in inflammatory diseases. We show that neratinib reduces neutrophilic migration o an inflammatory site in zebrafish larvae. Neratinib upregulates efferocytosis and reduces the number of persisting neutrophil corpses in mouse models of acute, but not chronic, lung injury, suggesting that the drug may have therapeutic benefits in acute inflammatory settings. Phosphoproteomic analysis of human neutrophils shows that neratinib modifies the phosphorylation of proteins regulating apoptosis, migration, and efferocytosis. This work identifies a potential mechanism for neratinib in treating acute lung inflammation by upregulating the clearance of dead neutrophils and, through examination of the neutrophil phosphoproteome, provides important insights into the mechanisms by which this may be occurring

Beyond 'Criminology vs. Zemiology': Reconciling crime with social harm

Since its emergence at the start of the twenty-first century, zemiology and the field of harm studies more generally, has borne an ambiguous and, at times, seemingly antipathetic relationship with the better-established field of criminology. Whilst the tension between the perspectives is, at times, overstated, attempts to reconcile the perspectives have also proved problematic, such that, at present, it appears that they risk either becoming polarized into mutually antagonistic projects, or harmonized to the point that zemiology is simply co-opted within criminology. Whilst tempting to view this as nothing more than an academic squabble, it is the central argument put forward in this chapter that the current trend towards either polariziaton or harmonization of the criminological and zemiological projects, risks impoverishing both perspectives, both intellectually and, more fundamentally, in terms of their capacity to effect meaningful social change. To this end, this chapter offers a critical reflection of recent attempts to reconcile the social harm perspective with criminology, focussing in particular on Majid Yar’s attempts to do so using the concept of ‘recognition’ derived from critical theory. It is suggested that such attempts, whilst important in the contribution they make to developing a theory of harm, are necessarily flawed by their reliance on an implicit assumption of a shared conception of harm underpinning both the concept of ‘crime’ and ‘social harm’. By contrast, it is the central argument put forward in this chapter that zemiology and criminology are best understood as divergent normative projects which, whilst sharing many of the same goals with regards to the improvement of the criminal justice system and the tackling of social problems, differ primarily in the means by which they seek to achieve these. Therefore, rather than denying this debate through the collapsing of one perspective into the other, or polarizing them into hostiles camps, it is only by recognising the nature of this debate and fostering dialogue between the perspectives that we can achieve our shared goals and effect meaningful change

Collateral damage to marine and terrestrial ecosystems from Yankee whaling in the 19th century

Yankee whalers of the 19th century had major impacts on populations of large whales, but these leviathans were not the only taxa targeted. Here, we describe the “collateral damage,” the opportunistic or targeted taking of nongreat whale species by the American whaling industry. Using data from 5,064 records from 79 whaling logs occurring between 1840 and 1901, we show that Yankee whalers captured 5,255 animals across three large ocean basins from 32 different taxonomic categories, including a wide range of marine and terrestrial species. The taxa with the greatest number of individuals captured were walruses (Odobenus rosmarus), ducks (family Anatidae), and cod (Gadus sp.). By biomass, the most captured species were walruses, grampus (a poorly defined group within Odontoceti), and seals (family Otariidae). The whalers captured over 2.4 million kg of nongreat whale meat equaling approximately 34 kg of meat per ship per day at sea. The species and areas targeted shifted over time in response to overexploitation of whale populations, with likely intensive local impacts on terrestrial species associated with multiyear whaling camps. Our results show that the ecosystem impacts of whaling reverberated on both marine and coastal environments

Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial

Background Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy

"Give me some space" : exploring youth to parent aggression and violence

A small scale qualitative project, undertaken by an interdisciplinary domestic violence research group involving academic researchers and research assistants, with colleagues from Independent Domestic Abuse Services (IDAS), investigated youth aggression and violence against parents. Following the literature review, data was generated through several research conversations with young people (n = 2), through semi-structured interviews with mothers (n = 3) and practitioners (n = 5), and through a practitioner focus group (n = 8). Thematic analysis and triangulation of the data from parents, practitioners and young people, elicited interconnected and complex overarching themes. Young people could be both victim and perpetrator. The witnessing or experiencing of domestic aggression and violence raised the concept of ‘bystander children’. The impact of young people experiencing familial violence was underestimated by parents. For practitioners, the effects of working with domestic violence was shown to be significant - both positively and negatively

Type 2 Diabetes Variants Disrupt Function of SLC16A11 through Two Distinct Mechanisms

Type 2 diabetes (T2D) affects Latinos at twice the rate seen in populations of European descent. We recently identified a risk haplotype spanning SLC16A11 that explains ∼20% of the increased T2D prevalence in Mexico. Here, through genetic fine-mapping, we define a set of tightly linked variants likely to contain the causal allele(s). We show that variants on the T2D-associated haplotype have two distinct effects: (1) decreasing SLC16A11 expression in liver and (2) disrupting a key interaction with basigin, thereby reducing cell-surface localization. Both independent mechanisms reduce SLC16A11 function and suggest SLC16A11 is the causal gene at this locus. To gain insight into how SLC16A11 disruption impacts T2D risk, we demonstrate that SLC16A11 is a proton-coupled monocarboxylate transporter and that genetic perturbation of SLC16A11 induces changes in fatty acid and lipid metabolism that are associated with increased T2D risk. Our findings suggest that increasing SLC16A11 function could be therapeutically beneficial for T2D.
