Welcomed as a milestone in the governance of transnational migration, the adoption of the Global Compact for Safe, Orderly, and Regular Migration marked a significant step forward in international cooperation on migration governance. Through a critical evaluation of its normative and structural features, this paper evaluates the strengths, weaknesses, tensions and contradictions within the compact. It finds that the compact is marked by innovative and ambitious objectives and gives recognition to the diversity and complexity of migration practices. However, its amplification of state sovereignty, its perpetuation of classical liberal statist ideals, and its ambiguity concerning the social-structural and institutional conditions necessary to protect migrants' rights and interests risk undermining its implementation and effectiveness. The paper argues that this framework is best understood as a progressive neoliberal model that relies on the virtue of states over legal and justice-based institutional mechanisms for its authority and implementation. This model risks reinforcing status quo power relations and is insufficient to achieve its stated objectives. [ABSTRACT FROM AUTHOR]

Sex-linked differences in mitochondrial ATP production, enzyme activities, and reactive oxygen species generation have been reported in multiple tissue and cell types. While the effects of reproductive hormones underlie many of these differences, regulation of sexually dimorphic mitochondrial function has not been fully characterized. We hypothesized that sex-specific DNA methylation contributes to sex-specific expression of nuclear genes that influence mitochondrial function. Herein, we analysed DNA methylation data specifically focused on nuclear-encoded mitochondrial genes in 191 males and 190 females. We found 596 differentially methylated sites (DMSs) (FDR p < 0.05), corresponding to 324 genes, with at least a 1% difference in methylation between sexes. To investigate the potential functional significance, we utilized gene expression microarray data. Of the 324 genes containing DMSs, 17 showed differences in gene expression by sex. Particularly striking was that ATP5G2, encoding subunit C of ATP synthase, contains seven DMSs and exhibits a sex difference in expression (p = 0.04). Finally, we also found that alterations in DNA methylation associated with in utero tobacco smoke exposure were sex-specific in these nuclear-encoded mitochondrial genes. Interestingly, the level of sex differences in DNA methylation at nuclear-encoded mitochondrial genes and the level of methylation changes associated with smoke exposure were less prominent than that of other genes. This suggests more conservative regulation of DNA methylation at these nuclear-encoded mitochondrial genes as compared to others. Overall, our findings suggest that sex-specific DNA methylation may help establish sex differences in expression and function and that sex-specific alterations in DNA methylation in response to exposures could contribute to sex-variable toxicological responses.

The suicide rate (currently 14 per 100,000) has barely changed in the United States over the past 100 years. There is a need for new ways of preventing suicide. Further, research has revealed that suicidal thoughts and behaviors and the factors that drive them are dynamic, heterogeneous, and interactive. Most existing interventions for suicidal thoughts and behaviors are infrequent, not accessible when most needed, and not systematically tailored to the person using their own data (e.g., from their own smartphone). Advances in technology offer an opportunity to develop new interventions that may better match the dynamic, heterogeneous, and interactive nature of suicidal thoughts and behaviors. Just-In-Time Adaptive Interventions (JITAIs), which use smartphones and wearables, are designed to provide the right type of support at the right time by adapting to changes in internal states and external contexts, offering a promising pathway toward more effective suicide prevention. In this review, we highlight the potential of JITAIs for suicide prevention, challenges ahead (e.g., measurement, ethics), and possible solutions to these challenges. [ABSTRACT FROM AUTHOR]

Non-Alcoholic fatty liver disease (NAFLD) is the leading cause of chronic liver disease in children. Epigenetic alterations, such as through DNA methylation (DNAm), may link adverse childhood exposures and fatty liver and provide non-invasive methods for identifying children at high risk for NAFLD and associated metabolic dysfunction. We investigated the association between differential DNAm and liver fat content (LFC) and liver injury in pre-adolescent children. Leveraging data from the Newborn Epigenetics Study (NEST), we enrolled 90 mother-child dyads and used linear regression to identify CpG sites and differentially methylated regions (DMRs) in peripheral blood associated with LFC and alanine aminotransferase (ALT) levels in 7–12yo children. DNAm was measured using Infinium HumanMethylationEPIC BeadChips (Illumina). LFC and fibrosis were quantified by magnetic resonance imaging proton density fat fraction and elastography. Median LFC was 1.4% (range, 0.3–13.4%) and MRE was 2.5 kPa (range, 1.5–3.6kPa). Three children had LFC ≥ 5%, while six (7.6%) met our definition of NAFLD (LFC ≥ 3.7%). All children with NAFLD were obese and five were Black. LFC was associated with 88 DMRs and 106 CpGs (FDR<5%). The top two CpGs, cg25474373 and cg07264203, mapped to or near RFTN2 and PRICKLE2 genes. These two CpG sites were also significantly associated with a NAFLD diagnosis. As higher LFC associates with an adverse cardiometabolic profile already in childhood, altered DNAm may identify these children early in disease course for targeted intervention. Larger, longitudinal studies are needed to validate these findings and determine mechanistic relevance. [ABSTRACT FROM AUTHOR]

Cannabis use in the United States is increasing, with highest consumption among men at their peak reproductive years. We previously demonstrated widespread changes in sperm DNA methylation with cannabis exposure in humans and rats, including genes important in neurodevelopment. Here, we use an in vitro human spermatogenesis model to recapitulate chronic cannabis use and assess DNA methylation at imprinted and autism spectrum disorder (ASD) candidate genes in spermatogonial stem cell (SSC)- and spermatid-like cells. Methylation at maternally imprinted genes SGCE and GRB10 was significantly altered in SSC- and spermatid-like cells, respectively, while PEG3 was significantly differentially methylated in spermatid-like cells. Two of ten randomly selected ASD candidate genes, HCN1 and NR4A2, had significantly altered methylation with cannabis exposure in SSC-like cells. These results support our findings in human cohorts and provide a new tool with which to gain mechanistic insights into the association between paternal cannabis use and risk of ASD in offspring.

Hand disease severity in people with systemic sclerosis (SSc) arises from connective tissue and vascular changes causing functional limitations, pain, and disability. Fatigue is not well-understood in SSc and reported to be highly distressing. It is not known how fatigue relates to these disease changes. The objective of this study was to identify which elements of hand disease severity contribute to fatigue in individuals with SSc. Five online databases and Google Scholar were searched to identify publications through 2021 presenting data related to hand disease severity and fatigue. Five articles met the inclusion criteria. The samples were 72–91% female, and 35–100% with diffuse SSc. Measures of disease severity included skin thickening (modified Rodnan score), joint involvement (mobility, tenderness, swelling), and digital ulcers. Fatigue was measured by various self-report. Joint involvement was strongly associated with fatigue. Skin thickening weakly associated with fatigue. The perceived interference of digital ulcers in daily activities was related to fatigue. Few studies have examined how fatigue relates to hand disease severity. While joint involvement was associated with fatigue over time and in cross-sectional studies, digital ulcers may be associated with fatigue indirectly. A conceptual model is proposed with implications for future research. Structural disease changes that manifest in the hands, is often associated with pain, disability, and fatigue in SSc. Fatigue is one of the most distressing symptoms of SSc and reported by 61–90% of individuals with SSc, but is not well characterized. Of measures of hand disease severity, joint involvement (contractures, swollen and tender joints) is most associated with fatigue in individuals with SSc and more so if pain is involved. A better understanding of the physiological features of disease and fatigue could provide insight into development of fatigue management interventions and help rheumatology providers work with patients to manage their fatigue. Rehabilitation assessments and interventions for hand disability need to be considered as important elements in improving all elements of quality of life for individuals with systemic sclerosis.

POVERTY ,WEALTH ,POVERTY reduction - Abstract
In this paper I use a feminist relational approach to critically examine contemporary mainstream assumptions in the field of development concerning the relationship between poverty and prosperity. I show how these assumptions underpin the policies and practices of poverty alleviation within international development institutions. I argue that when prosperity is understood as a condition of independence actualized through processes of maximum extraction, exploitation, and accumulation, the persistence of poverty and continued exploitation of social and ecological systems seems inevitable. This analysis reveals how the processes of defining and measuring poverty and prosperity as discrete conditions, binary opposites on a development spectrum masks the relational nature of poverty and prosperity whereby the pursuit of prosperity in global capitalist systems drives the production of poverty across spaces and places. Further, it ignores the ecological embeddedness and social interdependence of human beings for existence, survival, and well-being. The paper provides insights from a feminist relational perspective on the possibilities of thinking about prosperity beyond extractionism. [ABSTRACT FROM AUTHOR]

Due to the recent advancements in wearables and sensing technology, health scientists are increasingly developing mobile health (mHealth) interventions. In mHealth interventions, mobile devices are used to deliver treatment to individuals as they go about their daily lives. These treatments are generally designed to impact a near time, proximal outcome such as stress or physical activity. The mHealth intervention policies, often called just-in-time adaptive interventions, are decision rules that map an individual's current state (e.g., individual's past behaviors as well as current observations of time, location, social activity, stress, and urges to smoke) to a particular treatment at each of many time points. The vast majority of current mHealth interventions deploy expert-derived policies. In this article, we provide an approach for conducting inference about the performance of one or more such policies using historical data collected under a possibly different policy. Our measure of performance is the average of proximal outcomes over a long time period should the particular mHealth policy be followed. We provide an estimator as well as confidence intervals. This work is motivated by HeartSteps, an mHealth physical activity intervention. for this article are available online. [ABSTRACT FROM AUTHOR]

DNA methylation is highly sensitive to in utero perturbations and has an established role in both embryonic development and regulation of gene expression. The foetal genetic component has been previously shown to contribute significantly to the timing of birth, yet little is known about the identity and behaviour of individual genes. The aim of this study was to test the extent genome-wide DNA methylation levels in umbilical cord blood were associated with gestational age at birth (GA). Findings were validated in an independent sample and evidence for the regulation of gene expression was evaluated for cis gene relationships in specimens with multi-omic data. Genome-wide DNA methylation, measured by the Illumina Infinium Human Methylation 450 K BeadChip, was associated with GA for 2,372 CpG probes (5% FDR) in both the Pregnancy, Race, Environment, Genes (PREG) and Newborn Epigenetic Study (NEST) cohorts. Significant probes mapped to 1,640 characterized genes and an association with nearby gene expression measures obtained by the Affymetrix HG-133A microarray was found for 11 genes. Differentially methylated positions were enriched for actively transcribed and enhancer chromatin states, were predominately located outside of CpG islands, and mapped to genes enriched for inflammation and innate immunity ontologies. In both PREG and NEST, the first principal component derived from these probes explained approximately one-half (58.1% and 47.8%, respectively) of the variation in GA. Gene pathways identified are consistent with the hypothesis of pathogen detection and response by the immune system to elicit premature labour as a consequence of unscheduled inflammation.

Disabled individuals are significantly underrepresented as care providers within the healthcare system. One of the institutional barriers are professional competencies established from an ableist viewpoint. We investigated the client's perspectives on the professionalism of disabled clinicians. Focus groups and interviews were conducted with twenty-seven disabled and non-disabled participants. Participants were asked about their expectations and perceptions of professionalism from disabled clinicians. Three themes were identified: Positive impacts - highlighting the benefits of having disabled clinicians; As long as... - suggesting that professionalism should not be impacted provided that certain criteria are met; and to disclosure or not to disclose - providing rationale for and against disclosure of a disability to a client. Results challenge ableist beliefs about what constitutes professional behaviour and suggest that health professions should adopt a non-ableist appreciation for the contributions of disabled clinicians and foster the inclusion of disabled clinicians.

- Abstract
Parental cannabis use has been associated with adverse neurodevelopmental outcomes in offspring, but how such phenotypes are transmitted is largely unknown. Using reduced representation bisulphite sequencing (RRBS), we recently demonstrated that cannabis use is associated with widespread DNA methylation changes in human and rat sperm. Discs-Large Associated Protein 2 (DLGAP2), involved in synapse organization, neuronal signaling, and strongly implicated in autism, exhibited significant hypomethylation (p < 0.05) at 17 CpG sites in human sperm. We successfully validated the differential methylation present in DLGAP2 for nine CpG sites located in intron seven (p < 0.05) using quantitative bisulphite pyrosequencing. Intron 7 DNA methylation and DLGAP2 expression in human conceptal brain tissue were inversely correlated (p < 0.01). Adult male rats exposed to delta-9-tetrahydrocannabinol (THC) showed differential DNA methylation at Dlgap2 in sperm (p < 0.03), as did the nucleus accumbens of rats whose fathers were exposed to THC prior to conception (p < 0.05). Altogether, these results warrant further investigation into the effects of preconception cannabis use in males and the potential effects on subsequent generations. [ABSTRACT FROM AUTHOR]

EXPERIENCE , *BENEFICIARIES - Abstract
Utilising a case study methodological approach to analyse the Irish practitioner experience, this article examines if the introduction of results-based frameworks (RBFs) have led to greater impact and accountability to beneficiaries. The findings point to evidence of early resistance to RBFs based upon concerns regarding resources, inflexibility in programming, and the perceived focus on accountability to donors over beneficiaries. However, findings also point to opportunities that could facilitate more effective development in practice. Indications suggest RBFs may facilitate a greater understanding of complexity, increased focus on outcomes and impact through a systematic use of baseline measurements, and improved adaptive programming.

Gender norms and learned practices of student teachers can influence their performance in practice, either fixing or challenging, gendered social norms and expectations. This paper shares the findings of a multi-year mixed-methods research project that explored the understandings of gender norms and experiences of students and staff within a large teacher-training college in Tanzania. Data was collected to inform a wider gender mainstreaming initiative across the institution. Using a blend of quantitative and qualitative methods, the findings identified a strict and rigid gender binary which seemed to inform attitudes and practices of teaching and learning. Furthermore, it uncovered heterogeneous forms of gendered domination that were experienced by staff and pupils within the institution. The findings suggest that stand-alone 'female only' gender mainstreaming strategies may not be sufficient to achieve a gender equitable environment within the institution. Rather, it suggests that a whole-of-community approach is necessary to unravel deep-rooted biases and to tackle diverse forms of domination that affect different members of the college community in different ways. Such findings are particularly important in light of the epistemic power that is conferred on teacher-graduates and that is transferred through teaching practices to communities across Tanzania.

Background: Many pregnant women in the United States have suboptimal vitamin D, but the impact on infant development is unclear. Moreover, no pregnancy-specific vitamin D recommendations have been widely accepted.Aims: Given the ubiquitous expression of vitamin D receptors in the brain, we investigated the association between early prenatal plasma 25-hydroxyvitamin D (25(OH)D) concentrations and children's social and emotional development in the Newborn Epigenetic Study, a prospective study of pregnancies from 2009 to 2011 in Durham, North Carolina.Methods: We measured 25(OH)D concentrations in first or second trimester plasma samples and categorized 25(OH)D concentrations into quartiles. Covariates were derived from maternal questionnaires. Mothers completed the Infant Toddler Social-Emotional Development Assessment when children were 12-24 months of age. We used multivariable linear regression to evaluate associations between 25(OH)D and specific behavior scores, adjusted for season of blood draw, maternal age, education, parity, smoking, marital status, prepregnancy BMI, and infant gender. We investigated effect-measure modification by race/ethnicity.Results: Of the 218 mother-infant pairs with complete data, Black mothers had much lower 25(OH)D concentrations as compared to White and Hispanic mothers. After adjustment, lower prenatal 25(OH)D was associated with slightly higher (less favorable) Internalizing scores among White children, but lower (more favorable) Internalizing scores among Black and Hispanic children. Lower prenatal 25(OH)D also appears to be associated with higher (less favorable) dysregulation scores, though only among White and Hispanic children.Conclusions: Though imprecise, preliminary results warrant further investigation regarding a role for prenatal vitamin D on children's early social and emotional development.

- Abstract
Pre-pregnancy obesity is an established risk factor for adverse sex-specific cardiometabolic health in offspring. Epigenetic alterations, such as in DNA methylation (DNAm), are a hypothesized link; however, sex-specific epigenomic targets remain unclear. Leveraging data from the Newborn Epigenetics Study (NEST) cohort, linear regression models were used to identify CpG sites in cord blood leukocytes associated with pre-pregnancy obesity in 187 mother-female and 173 mother-male offsprings. DNAm in cord blood was measured using the Illumina HumanMethylation450k BeadChip. Replication analysis was conducted among the Avon Longitudinal Study of Parents and Children (ALSPAC) cohort. Associations between pre-pregnancy obesity-associated CpG sites and offspring BMI z-score (BMIz) and blood pressure (BP) percentiles at 4–5-years of age were also examined. Maternal pre-pregnacy obesity was associated with 876 CpGs in female and 293 CpGs in male offspring (false discovery rate <5%). Among female offspring, 57 CpG sites, including the top 18, mapped to the TAPBP gene (range of effect estimates: −0.83% decrease to 4.02% increase in methylation). CpG methylation differences in the TAPBP gene were also observed among males (range of effect estimates: −0.30% decrease to 2.59% increase in methylation). While technically validated, none of the TAPBP CpG sites were replicated in ALSPAC. In NEST, methylation differences at CpG sites of the TAPBP gene were associated with BMI z-score (cg23922433 and cg17621507) and systolic BP percentile (cg06230948) in female and systolic (cg06230948) and diastolic (cg03780271) BP percentile in male offspring. Together, these findings suggest sex-specific effects, which, if causal, may explain observed sex-specific effects of maternal obesity. [ABSTRACT FROM AUTHOR]

In mobile health interventions aimed at behavior change and maintenance, treatments are provided in real time to manage current or impending high-risk situations or promote healthy behaviors in near real time. Currently there is great scientific interest in developing data analysis approaches to guide the development of mobile interventions. In particular data from mobile health studies might be used to examine effect moderators—individual characteristics, time-varying context, or past treatment response that moderate the effect of current treatment on a subsequent response. This article introduces a formal definition for moderated effects in terms of potential outcomes, a definition that is particularly suited to mobile interventions, where treatment occasions are numerous, individuals are not always available for treatment, and potential moderators might be influenced by past treatment. Methods for estimating moderated effects are developed and compared. The proposed approach is illustrated using BASICS-Mobile, a smartphone-based intervention designed to curb heavy drinking and smoking among college students. Supplementary materials for this article are available online. [ABSTRACT FROM AUTHOR]

- Abstract
Excessive inflammation during pregnancy alters homeostatic mechanisms of the developing fetus and has been linked to adverse pregnancy outcomes. An anti-inflammatory diet could be a promising avenue to combat the pro-inflammatory state of pregnancy, particularly in obese women, but we lack mechanistic data linking this dietary pattern during pregnancy to inflammation and birth outcomes. In an ethnically diverse cohort of 1057 mother-child pairs, we estimated the relationships between dietary inflammatory potential [measured via the energy-adjusted dietary inflammatory index (E-DII™)] and birth outcomes overall, as well as by offspring sex and maternal pre-pregnancy body mass index (BMI). In a subset of women, we also explored associations between E-DII, circulating cytokines (n = 105), and offspring methylation (n = 338) as potential modulators of these relationships using linear regression. Adjusted regression models revealed that women with pro-inflammatory diets had elevated rates of preterm birth among female offspring [β = −0.22, standard error (SE) = 0.07,P<0.01], but not male offspring (β=0.09, SE = 0.06,P<0.12) (Pinteraction= 0.003). Similarly, we observed pro-inflammatory diets were associated with higher rates of caesarean delivery among obese women (β = 0.17, SE = 0.08,P= 0.03), but not among women with BMI <25 kg/m2(Pinteraction= 0.02). We observed consistent inverse associations between maternal inflammatory cytokine concentrations (IL-12, IL-17, IL-4, IL-6, and TNFα) and lower methylation at theMEG3regulatory sequence (P<0.05); however, results did not support the link between maternal E-DII and circulating cytokines. We replicate work by others on the association between maternal inflammatory diet and adverse pregnancy outcomes and provide the first empirical evidence supporting the inverse association between circulating cytokine concentrations and offspring methylation.

Despite inclusive rhetoric, disabled peoples’ participation in the Health and Human Service (HHS) professions remains limited. This study explores the perspectives of individuals in the HHS sector regarding inclusion-related barriers and facilitators. We found three mechanisms that marginalize disabled people in HHS education and professions: dominant disabling discourses; discriminatory design within programmes and universities; and oppressive interactions. The inclusion of disabled individuals is vital for ensuring HHS professionals represent the populations they serve. By challenging the views of educators, professionals, and scholars, these findings may become part of the foundation upon which change can be created. [ABSTRACT FROM AUTHOR]

In this paper, we unpack the complex drivers of educational exclusion and non-progression of female adolescents in rural Tanzania. Despite targeted government policies, donor funding, and multiple development interventions, this area has witnessed declining rates of academic progression for young girls over the past decade. Based upon empirical research examining the educational patterns and experiences in the community of Milola Ward, Lindi Rural, Tanzania, this contribution provides critical insights into the range of factors that influence educational attainments in a rural, resource poor context, including structural and agent-based, gendered and non-gendered factors. From a theoretical perspective, the case of Lindi Rural sheds light on the interconnection between educational attainment and gender (in)justice. It points to the need for a more expansive account of gender justice that includes consideration of principles of epistemic empowerment.

The realisation of rights and enforcement of correlative duties through practice and politics legitimate the use of force against some, to protect and fulfil the rights of others. When a conflict occurs, whose rights and which rights should take priority require clarification. Land grabs represent a conflict not just between use and exchange values but also potentially between different types of rights – such as property rights and the right to the means of subsistence. In such cases, it seems that the dictum ‘between equal rights force decides’ seems to be particularly applicable. This paper explores recent experiences of displaced people in the Karamoja and Teso regions of North Eastern Uganda in order to examine this phenomenon. A socially inclusive and just epistemic perspective requires that we extend our gaze to take account of the local political dynamics and impacts on, and voices of, people who have been displaced and how their basic rights have been affected – ‘putting the last first’. The analysis suggests that the transition to formalised property regimes based on liberal conceptions of ‘rights’ represents a case where the language of rights is usurped to serve the interests of the powerful and privileged rather than challenging social injustice.

Behavioral and pharmacological treatments for children with attention deficit/hyperactivity disorder (ADHD) were evaluated to address whether endpoint outcomes are better depending on which treatment is initiated first and, in case of insufficient response to initial treatment, whether increasing dose of initial treatment or adding the other treatment modality is superior. Children with ADHD (ages 5–12,N= 146, 76% male) were treated for 1 school year. Children were randomized to initiate treatment with low doses of either (a) behavioral parent training (8 group sessions) and brief teacher consultation to establish a Daily Report Card or (b) extended-release methylphenidate (equivalent to .15 mg/kg/dose bid). After 8 weeks or at later monthly intervals as necessary, insufficient responders were rerandomized to secondary interventions that either increased the dose/intensity of the initial treatment or added the other treatment modality, with adaptive adjustments monthly as needed to these secondary treatments. The group beginning with behavioral treatment displayed significantly lower rates of observed classroom rule violations (the primary outcome) at study endpoint and tended to have fewer out-of-class disciplinary events. Further, adding medication secondary to initial behavior modification resulted in better outcomes on the primary outcomes and parent/teacher ratings of oppositional behavior than adding behavior modification to initial medication. Normalization rates on teacher and parent ratings were generally high. Parents who began treatment with behavioral parent training had substantially better attendance than those assigned to receive training following medication. Beginning treatment with behavioral intervention produced better outcomes overall than beginning treatment with medication. [ABSTRACT FROM PUBLISHER]

This pilot study was conducted to assess the feasibility and acceptability of 4 adaptive treatment strategies (ATSs) for adolescent depression to plan for a subsequent full-scale clinical trial. The ATSs aim to address 2 questions that arise when personalizing treatment: (a) For adolescents treated with Interpersonal Psychotherapy for depressed adolescents (IPT-A; Mufson et al., 2004), at what time point should therapists make the determination that the adolescent is not likely to respond if the initial treatment plan is continued (week 4 or week 8)? (b) For adolescents who are judged to need their treatment augmented, should the therapist increase the number of IPT-A sessions or add pharmacotherapy (fluoxetine)? A 16-week pilot sequential multiple assignment randomized trial (SMART) was conducted with 32 adolescents (Mage = 14.9) who had a diagnosis of major depressive disorder, dysthymic disorder, or depressive disorder not otherwise specified. Adolescents were primarily female (75%) and Caucasian (84.4%). Data regarding the feasibility and acceptability of the study and treatment procedures and treatment response rates were collected. Week 4 was the more feasible and acceptable decision point for assessing need for a change to treatment. Adolescents, parents, and therapists reported a range of attitudes about medication and more intensive therapy as treatment options. Results from the pilot study have yielded additional research questions for the full-scale SMART and will improve our ability to successfully conduct the trial. [ABSTRACT FROM PUBLISHER]

A stress prevention and mindfulness (SPAM) group is described, which is a 6-week psychoeducational and support group for teachers. The group incorporated psychoeducation about stress and utilized elements of Mindfulness-Based Stress Reduction (MBSR). The group was implemented in a public charter school in the Southwest. Preliminary evaluation conducted with two elements (session ratings and pre- and post-measures of mindfulness, teacher perceptions of demands and resources in their classroom, and job satisfaction) was supportive of teachers' satisfaction with the group. Implications and future research directions are discussed. [ABSTRACT FROM AUTHOR]

Childhood stressors including physical abuse predict adult cancer risk. Prior research portrays this finding as an indirect mechanism that operates through coping behaviors, including adult smoking, or through increased toxic exposures during childhood. Little is known about potential direct causal mechanisms between early-life stressors and adult cancer. Because prenatal conditions can affect gene expression by altering DNA methylation, with implications for adult health, we hypothesize that maternal stress may program methylation of cancer-linked genes during gametogenesis. To illustrate this hypothesis, we related maternal social resources to methylation at the imprinted MEG3 differentially methylated regulatory region, which has been linked to multiple cancer types. Mothers (n = 489) from a diverse birth cohort (Durham, North Carolina) provided newborns’ cord blood and completed a questionnaire. Newborns of currently married mothers showed lower (−0.321 SD,p < .05) methylation compared to newborns of never-married mothers, who did not differ from newborns whose mothers were cohabiting and others (adjusted for demographics). MEG3 DNA methylation levels were also lower when maternal grandmothers co-resided before pregnancy (−0.314 SD,p < .05). A 1-SD increase in prenatal neighborhood disadvantage also predicted higher methylation (−0.137 SD,p < .05). In conclusion, we found that maternal social resources may result in differential methylation of MEG3, which demonstrates a potential partial mechanism priming socially disadvantaged newborns for later risk of some cancers.

DUTY ,ETHICS ,INTERNATIONAL relief ,HUMANITARIAN assistance ,RESPONSIBILITY - Abstract
This paper examines the links between acting upon a duty to assist, responsibility for these actions, and how such actions link with incremental moral duties that can amass as a consequence of such action. More specifically, this paper is concerned with practices of international aid and assistance, whereby public and privately funded donations enable the actions of parties outside of the territorial and jurisdictional boundaries of a community and state to directly influence the functioning of that community, and the incremental moral duties to which such action can give rise. Using a Senian account of the basis of moral duty, it explains how agents are responsible for the outcomes of their acts of assistance, even when mediated through international institutional actors, and how such acts can give rise to accumulative duties and obligations that are not bound or constrained by territorial boundaries or pre-existing special obligations.

Background: Depression is a common mental health problem among Chinese elderly, but it often goes undiagnosed and untreated. Despite tin increase in the population of elderly Chinese immigrants in the US, there have been few published studies on this topic. Objective: Our purpose was to determine the extent of depression in the participant population, using an updated Chinese translation of the original 30-item Geriatric Depression Scale (GDS; Yesavage et al., 1983). Study Design: A convenience sample of 102 Mandarin speaking Chinese elderly participants in two senior centers in Santa Clara County, CA was recruited. Results: A total of 29.4% of participants showed symptoms of depression, higher than the range found in the older adult American population (13=20%). Those most likely to be depressed ranged in age from 60 to 69 years (32%), lived with their children (37%), rated their financial and health status as below average, had less than a high school education, and lived in the US for less than 5 years. Conclusion: This updated Chinese translation of the GDS is a promising screening measure to detect depressive symptoms in elderly Chinese. [ABSTRACT FROM AUTHOR]

For many years, subset analysis has been a popular topic for the biostatistics and clinical trials literature. In more recent years, the discussion has focused on finding subsets of genomes which play a role in the effect of treatment, often referred to as stratified or personalized medicine. Though highly sought after, methods for detecting subsets with altering treatment effects are limited and lacking in power. In this article we discuss variable selection for qualitative interactions with the aim to discover these critical patient subsets. We propose a new technique designed specifically to find these interaction variables among a large set of variables while still controlling for the number of false discoveries. We compare this new method against standard qualitative interaction tests using simulations and give an example of its use on data from a randomized controlled trial for the treatment of depression.

Navigating the biomedical, emotional, and logistical complexity of end-of-life (EOL) care requires seamless interprofessional teamwork. Unfortunately, EOL care, interprofessional collaboration, and the role of support services such as hospice are not adequately emphasized in nursing and medical curricula. This article describes a student-run program, entitled the “HeArt of Medicine”, which was designed to foster a reflective and collaborative approach to EOL care. The program consists of three workshops with a novel blend of art, science, and practical information, highlighting the need for interprofessional teamwork. Participants were surveyed before and after the workshops on their attitudes toward EOL care. Composite participant scores after workshops demonstrated increased comfort with and knowledge of EOL care topics (p = 0.001). The results show that this program has had a positive impact on participants’ knowledge, comfort, and collaboration in EOL settings. [ABSTRACT FROM PUBLISHER]

To date, the majority of molecular genetic studies in algae have utilized a fairly limited range of markers such as the plastid rbc L gene and spacer, the mitochondrial cox 2-3 spacer or the nuclear ribosomal DNA and spacers. The lack of available markers has been particularly problematic in studies of within-species variation. Whilst microsatellites are now being developed in many algal species, there remains a need for universal markers that can be applied to a wide range of species. The increasing availability of complete plastid genome sequences for several algae has allowed us to develop two sets of universal primers, similar to those available in higher plants, for the amplification of coding and non-coding regions of the plastid genome in red and green algae. These markers are expected to be useful in a broad range of algal population genetic and phylogenetic studies. [ABSTRACT FROM AUTHOR]

- Abstract
An exploratory study examined some of the book-reading dimensions (e.g., interactive book reading followed by story retelling, the effects of reading stories to small versus large groups, and the effects of repeated reading) considered most beneficial for developing language competence, an important prerequisite of literacy acquisition. The purpose was to determine the effects of an interactive book reading and story retelling approach (child-centered strategy) used with both small and large groups on story comprehension and narrative-skill development. Eighty-six children enrolled in six Head Start classrooms participated in the 8-week study. No significant differences were found in posttest means on any of the language competence measures analyzed. On the other hand, descriptive data collected through teacher interviews suggested a favorable impact on language and early literacy skills when interactive book reading followed by retelling and repeated reading are incorporated into book-reading experiences for preschool children.

The Theil-Sen estimator of the slope parameter in simple linear regression is extended to data with both the response and the covariate subject to censoring. Based on inverting a suitable version of Kendall's r statistic, this estimator requires weak assumptions and is simple to compute, and a simple estimate of its asymptotic variance is obtained. A second extension of the Theil-Sen estimator, based on a direct estimation of the median of pairwise slopes, is given. These estimators are compared numerically with versions of Schmitt's estimator and applied to two data sets from the recent astronomical literature. [ABSTRACT FROM AUTHOR]

CAUSATION (Philosophy) , *PAIRED associate learning - Abstract
In two causal induction experiments subjects rated the importance of pairs of candidate causes in the production of a target effect; one candidate was present on every trial (constant cause), whereas the other was present on only some trials (variable cause). The design of both experiments consisted of a factorial combination of two values of the variable cause's covariation with the effect and three levels of the base rate of the effect. Judgements of the constant cause were inversely proportional to the level of covariation of the variable cause but were proportional to the base rate of the effect. The judgements were consistent with the predictions derived from the Rescorla-Wagner (1972) model of associative learning and with the predictions of the causal power theory of the probabilistic contrast model (Cheng, 1997) or ''power PC theory''. However, judgements of the importance of the variable candidate cause were proportional to the base rate of the effect, a phenomenon that is in some cases anticipated by the power PC theory. An alternative associative model, Pearce's (1987) similaritybased generalization model, predicts the influence of the base rate of the effect on the estimates of both the constant and the variable cause.
