Employees’ organizational citizenship behavior (OCB) is an important determinant of organizational effectiveness; hence, scholars and practitioners are particularly interested in the factors, mechanisms, and conditions that promote such behaviors. Guided by the ability–motivation–opportunity framework, we draw on the social cognitive theory of moral thought and action to conceptualize a model that delineates the role of ethics-oriented human resource management (HRM) systems in promoting OCBs through the mediating role of employees’ moral attentiveness. We also refer to the job demands–resources theory to describe the moderating role of work-family balance in the indirect relationship between HRM systems and OCBs. The findings of an experiment involving 157 working adults (Study 1) and a three-wave field survey of 328 employees (Study 2) converge to support the hypothesized direct and indirect (via moral attentiveness) relationships between ethics-oriented HRM systems and OCBs as well as the first-stage moderating role of work-family balance.
Stochastic embeddings of finite metric spaces into graph-theoretic trees have proven to be a vital tool for constructing approximation algorithms in theoretical computer science. In the present work, we build out some of the basic theory of stochastic embeddings in the infinite setting with an aim toward applications to Lipschitz free space theory. We prove that proper metric spaces stochastically embedding into $\mathbb {R}$-trees have Lipschitz free spaces isomorphic to $L^1$-spaces. We then undergo a systematic study of stochastic embeddability of Gromov hyperbolic metric spaces into $\mathbb {R}$-trees by way of stochastic embeddability of their boundaries into ultrametric spaces. The following are obtained as our main results: (1) every snowflake of a compact, finite Nagata-dimensional metric space stochastically embeds into an ultrametric space and has Lipschitz free space isomorphic to $\ell ^1$, (2) the Lipschitz free space over hyperbolic n-space is isomorphic to the Lipschitz free space over Euclidean n-space and (3) every infinite, finitely generated hyperbolic group stochastically embeds into an $\mathbb {R}$-tree, has Lipschitz free space isomorphic to $\ell ^1$, and admits a proper, uniformly Lipschitz affine action on $\ell ^1$.
A youth mental health crisis is considered one of the great challenges of our time, and research and clinical services in child and adolescent psychiatry have become a priority for governments and funders. Academic leadership is needed to drive forward research. It is not clear how many senior academic leadership posts (professorships) there are in child and adolescent psychiatry, nor how this benchmarks against a similarly sized medical specialty.
Aims
This study aimed to determine the number of professorships in child and adolescent psychiatry in the UK and Ireland compared to a similarly sized specialty. A secondary aim was to identify the number of clinical trials registered for mental and behavioural disorders in children.
Method
We identified registered specialists in child and adolescent psychiatry and a similarly sized specialty who held full professorships in medical schools. We searched the International Standard Randomised Controlled Trial Number (ISRCTN) and ClinicalTrials.gov for trials.
Results
As of 23 March 2023, there were 1725 doctors on the General Medical Council's (GMC) specialist register in child and adolescent psychiatry. The closest specialty in terms of number of registered specialists was neurology (N = 1724). We identified 24 professors in child and adolescent psychiatry across the UK and Ireland, compared to 124 in neurology. For every intervention trial registered for mental and behavioural disorders in children, there were approximately ten trials registered for diseases of the nervous system.
Conclusions
Despite equivalent numbers of medical specialists in child and adolescent psychiatry and neurology, there is a striking disparity in the number of professorship appointments. While young peoples’ mental health has, ostensibly, become a priority for policy-makers and funders, this is not reflected in medical professorship appointments. The paucity of senior academic child and adolescent psychiatrists has real-world implications for training, research, innovation and service development in mental health services.
Natasha Abrahart was a physics student at the University of Bristol. She was suffering from depression and social anxiety disorder, which seriously impacted her ability to partake in oral assessments. Eventually, Natasha sadly took her own life. Her father, Dr Robert Abrahart, as personal representative and estate administrator, sued the University of Bristol for negligence and breach of sections 15, 19 and 20 of the Equality Act 2010, read with section 91(2)(a) and/or (f) of the same Act.1 Under such provisions, universities have a duty to provide reasonable adjustments and support, in educational provision and assessments, to disabled students, defined by section 6(1) of the Equality Act 2010 as ‘a physical or mental impairment’ which has ‘a substantial and long-term adverse effect’ on the ability to ‘carry out normal day-to-day activities’. However, Schedule 13, para 4(2), to the Equality Act 2010 exempts those assessments which constitute a competency standard, defined as ‘an academic, medical or other standard applied for the purpose of determining whether or not a person has a particular level of competence or ability’.2
To assess the therapeutic effects of probiotic oral therapy in pediatric patients with anorexia nervosa and to investigate its impact on intestinal flora composition, brain-gut peptide levels, and overall clinical outcomes. A retrospective study was conducted involving 100 children diagnosed with anorexia nervosa at Xingtang County People’s Hospital between January 2023 and June 2024. Patients were divided into two groups: a control group (n=50) receiving zinc gluconate oral solution alone and an observation group (n=50) receiving zinc gluconate plus probiotics. Outcome measures included intestinal flora analysis, brain-gut peptide levels (SS, NO), clinical efficacy, serum trace element levels (calcium, zinc, iron), and prognosis, including recurrence rates six months post-treatment. Baseline characteristics were similar between the two groups (P>0.05). After treatment, the observation group showed significantly higher levels of Bifidobacterium and Lactobacillus and lower levels of Enterobacter compared to the control group (P<0.05). Additionally, the observation group had lower levels of SS and NO (P<0.05), indicating improved brain-gut communication. Clinical efficacy was significantly higher in the observation group (P<0.05), with improved serum trace element levels (P<0.05 for calcium, zinc, and iron). Furthermore, the recurrence rate six months post-treatment was significantly lower in the observation group compared to the control group (P<0.05). Probiotic supplementation in children with anorexia nervosa effectively modulates intestinal flora, improves brain-gut peptide levels, and enhances clinical outcomes.
Liberals experience more distress than conservatives. Why? We offer a novel explanation, the social support hypothesis. Maintaining social support and avoiding exclusion are basic human motivations, but people differ in their sensitivity to the threat of social exclusion. Among people high in the personality trait neuroticism, exclusion easily triggers feelings of vulnerability and neediness. The social support hypothesis translates this to politics. Concerned with their own vulnerability, we find that neurotic people prefer policies of care – social welfare and redistribution – but not other left-wing policies. Specifically, it is anxiety – the facet of neuroticism tapping sensitivity to social threats – that drives this link. And it is only for people experiencing exclusion that anxiety predicts support for social welfare. Our results come from two experiments and four representative surveys across two continents. They help to resolve the puzzle of liberal distress while providing a new template for research on personality and politics.
H. H. Chan, K. S. Chua and P. Solé [‘Quadratic iterations to $\pi $ associated to elliptic functions to the cubic and septic base’, Trans. Amer. Math. Soc.355(4) (2002), 1505–1520] found that, for each positive integer d, there are theta series $A_d, B_d$ and $C_d$ of weight one that satisfy the Pythagoras-like relationship $A_d^2=B_d^2+C_d^2$. In this article, we show that there are two collections of theta series $A_{b,d}, B_{b,d}$ and $C_{b,d}$ of weight one that satisfy $A_{b,d}^2=B_{b,d}^2+C_{b,d}^2,$ where b and d are certain integers.
In the early stages of the COVID-19 pandemic, the treatment of cruise ships by coastal states was inconsistent, with some ships being allowed to dock while others were not. To that end, this Note focuses on the obligations that a coastal state owes to the individuals onboard the cruise ships in the context of the COVID-19 pandemic, including the rights to life and health. It further considers whether and how such rights are to be balanced with other countervailing considerations of such states, such as the risk of transmission to the local communities. This author concludes with the view that individuals onboard the cruise ships can, and should, consider turning to international human rights law for guidance and recourse. After all, the human rights regime is most suited for and accustomed to governing the relationship between individuals and a state, as compared to between states.
As relations between the United States and China have grown tenser, how has the Chinese Communist Party's (CCP) portrayal of the United States changed? And what might portrayals of the United States tell us about domestic messaging in China? This study systematically investigates CCP messaging about the United States in the contemporary era. To do this, we hand code, categorize and analyse 1,761 editorials about the United States published between 2003 and 2022 in People's Daily, the Party's flagship newspaper. In addition to showing a sustained rise in critical portrayals since 2018, we identify and elaborate three distinct critical narratives about the United States: it is a dangerous hegemon abroad, it has poor values at home, and it is increasingly weak and in decline. These narratives appear both independently and in combination and are often framed to contrast with portrayals of China. We argue that these narratives are not just negative propaganda to discredit the United States but can also be a strategy to promote a positive vision of the CCP's virtues and governance at home. This study contributes empirically and theoretically to research on propaganda and legitimation in China.
We aimed to study how hormonal status (oral contraceptive [OC] users vs naturally cycling [NC]) affects different dimensions and variability of psychological well-being, and how they relate to sex hormone levels (estradiol, progesterone, and testosterone).
Methods
Twenty-two NC participants and 18 OC users reported daily affective and physical symptoms and collected daily salivary samples across 28 days. Groups were compared using psychological well-being averages (linear mixed models), day-to-day variability (Levene’s test), and network models. Within NC participants, cycle phase effects and time-varying associations between hormones and psychological well-being were assessed using both person-centered mean and change (subtracting mean from daily score) scores.
Results
Lowered variability was found for OC users’ agitation, risk-taking, attractiveness, and energy levels. They showed lower overall ratings of happiness, attractiveness, risk-taking, and energy levels (range R2m = .004: .019) but also reported more relaxation, sexual desire, and better sleep quality (range R2m = .005; .01) compared to the NC group. The impact of sex hormones on psychological well-being varied significantly across cycle phases, with the largest effects for progesterone levels.
Conclusions
Our results confirm that hormonal status is associated with a range of psychological well-being domains beyond mood and sexual desire, including energy levels, feelings of attractiveness, risk taking, and agitation. Lowered variability in OC users versus NC participants fit with ‘emotional blunting’ as a possible mechanism behind OC’s side effects. Our findings that show the menstrual cycle and sex hormones differentially influenced markers of psychological well-being emphasize the need to adequately account for the menstrual cycle.
In 2017, the authors supervised the recovery of a pre-Hispanic stone sculpture near the community of La Victoria, in the Sierra de los Tuxtlas, southern Veracruz, Mexico. The fortuitous discovery of this monument afforded a rare research opportunity to conduct a controlled, systematic archaeological investigation of a known, but poorly documented, Early Classic–period (a.d. 300–450) sculptural tradition. Moreover, this archaeological salvage project facilitated a crucial dialogue with local stakeholders regarding the recovery and final disposition of the monument. This collaborative effort enabled researchers to wed governmental oversight and academic interests with the concerns of local stakeholders, thereby furthering the investigation, conservation, and public appreciation of Classic-period archaeology along Mexico's southern Gulf Lowlands.
Subjective cognition is a predictor of cognitive decline and previous work has identified age, education, and depression as predictors of subjective cognition. This study aimed to investigate whether several sleep characteristics were associated with subjective cognition above-and-beyond known predictors.
Methods:
Participants (N=3284, Mage=42.7 years, 48.5% female) completed an online study that included the Patient Health Questionnaire-4 (PHQ-4), Insomnia Severity Index (ISI), RU-SATED, Sleep Regularity Questionnaire (SRQ), and the 6-item PROMIS Cognitive Function. A 3-step hierarchical regression model predicted PROMIS Cognition scores, with Step 1 including age and education as predictors, Step 2 including age, education, and PHQ-4 scores, and Step 3 including all previous variables and sleep variables.
Results:
In Step 1 (R2=.03), age and education were significant predictors, while in Step 2 (R2=.36), PHQ-4 and education were significant, and age was no longer significant. In Step 3 (R2=.48), PHQ-4, ISI, RU-SATED, and SRQ scores were significant, while age and education were not significant. All steps accounted for a significant increase in variance (p’s<.001).
Conclusions:
Sleep characteristics were associated with subjective cognition above-and-beyond known predictors of age, education, and mood. Further research is needed to investigate whether changes in sleep characteristics are associated with changes in subjective cognition.
The current review will examine the field of food intake biomarkers and the potential use of such biomarkers. Biomarkers of food intake have the potential to be objective measures of intake thus addressing some of the limitations associated with self-reported dietary assessment methods. They are typically food derived biomarkers present in biological samples and distinct from endogenous metabolites. To date, metabolomic profiling has been successful in identifying several putative food intake biomarkers. With respect to food intake biomarkers there has been a proliferation of publications in this field. However, caution is needed when interpreting these as food intake biomarkers. Many have not been validated thus hampering their use. While much of the focus to date is on discovery of food intake biomarkers there are excellent examples of how to utilise these biomarkers in nutrition research. Applications include but are not limited to: (1) measurement of adherence to diets in intervention studies (2) objectively predicting intake with no reliance on self reported data and (3) calibrating self reported data in large epidemiological studies. Examples of these applications will be covered in this review. While significant progress is achieved to date in the food intake biomarkers field there are a number of key challenges that remain. Examples include lack of databases focused on food derived metabolites thus hindering the discovery of new biomarkers and the need for new statistical approaches to deal with multiple biomarkers for single foods. Addressing these and other key challenges will be key to development of future opportunities.
