Inclusive Leadership: Exploration of Individual and Situational Antecedents

In today’s increasingly diverse workforce, inclusive leadership has become an important focus for organizations. Inclusive leadership is the extent to which leaders foster a sense of belonging among group members and show that their uniqueness is valued. Researchers have shown that inclusive leadership positively affects subordinate outcomes, such as psychological safety, work engagement, and innovation. However, there is little research on the individual and situational characteristics that predict leaders acting in an inclusive manner. The current research analyzes the extent to which inclusive leadership is predicted by individual characteristics (e.g., personality, diversity beliefs), developmental experiences (e.g., leader training, mentorship), and organizational factors (e.g., organizational inclusive climate, senior leadership behavior). Findings revealed two personality traits to be significantly associated with inclusive leadership: Extraversion and Openness. Specifically, Extraversion was positively related to inclusive leadership, while Openness was negatively related to inclusive leadership. Furthermore, the current research demonstrated that inclusive leadership was positively related to subordinate affective organizational commitment, and negatively related to subordinate intention to quit. This research helps advance theory on inclusive leadership and suggests how organizations may increase inclusive leadership among their ranks. Implications for theory and practice, limitations, and directions for future research are discussed

The Tnfrh1 (Tnfrsf23) gene is weakly imprinted in several organs and expressed at the trophoblast-decidua interface

BACKGROUND: The Tnfrh1 gene (gene symbol Tnfrsf23) is located near one end of a megabase-scale imprinted region on mouse distal chromosome 7, about 350 kb distant from the nearest known imprinting control element. Within 20 kb of Tnfrh1 is a related gene called Tnfrh2 (Tnfrsf22) These duplicated genes encode putative decoy receptors in the tumor necrosis factor (TNF) receptor family. Although other genes in this chromosomal region show conserved synteny with genes on human Chr11p15.5, there are no obvious human orthologues of Tnfrh1 or Tnfrh2. RESULTS: We analyzed Tnfrh1 for evidence of parental imprinting, and characterized its tissue-specific expression. Tnfrh1 mRNA is detectable in multiple adult and fetal tissues, with highest expression in placenta, where in situ hybridization reveals a distinctive population of Tnfrh1-positive cells in maternal decidua, directly beneath the trophoblast giant cells. In offspring of interspecific mouse crosses, Tnfrh1 shows a consistent parent-of-origin-dependent allelic expression bias, with relative repression, but not silencing, of the paternal allele in several organs including fetal liver and adult spleen. CONCLUSIONS: Genes preferentially expressed in the placenta are predicted to evolve rapidly, and Tnfrh1 appears to be an example of this phenomenon. In view of its strong expression in cells at the fetal-maternal boundary, Tnfrh1 warrants further study as a gene that might modulate immune or trophic interactions between the invasive placental trophoblast and the maternal decidua. The preferential expression of Tnfrh1 from the maternal allele indicates weak functional imprinting of this locus in some tissues

Association between arterial stiffness and variations in estrogen-related genes

available in PMC 2010 April 1.Increased arterial stiffness and wave reflection have been identified as cardiovascular disease risk factors. In light of significant sex differences and the moderate heritability of vascular function measures, we hypothesized that variation in the genes coding for oestrogen receptors α (ESR1) and β (ESR2) and aromatase (CYP19A1) is associated with aortic stiffness and pressure wave reflection as measured by non-invasive arterial tonometry. In all, 1261 unrelated Framingham Offspring Study participants who attended the seventh examination cycle (mean age 62±10 years, 52% women) and had arterial tonometry and genotyping data were included in the study. Analysis of covariance was used to assess the association of polymorphisms with forward wave amplitude, augmented pressure, augmentation index (AI), carotid–femoral pulse wave velocity and mean arterial pressure with adjustment for potential confounders. In the sex-pooled analysis, those homozygous for the minor allele at any of four ESR1 variants that were in strong linkage disequilibrium ((TA)n, rs2077647, rs2234693 and rs9340799) had on an average 18% higher augmented pressure and 16% greater AI compared with carriers of one or two major alleles (P=0.0002–0.01). A similar magnitude of association was detected in those homozygous for the common allele at two ESR2 single-nucleotide polymorphisms (P=0.007–0.02). Our results are consistent with the hypothesis that variation in ESR1 and ESR2, but not CYP19A1, is associated with an increased wave reflection that may contribute to associations between these variants and adverse clinical events demonstrated earlier. Our findings will need to be replicated in additional cohorts

How do African SMEs respond to climate risks? Evidence from Kenya and Senegal

This paper investigates to what extent and how small and medium-sized enterprises (SMEs) in poor countries are adapting to climate risks using data from 325 SMEs in the semi-arid regions of Kenya and Senegal. There is a clear role for public policy in facilitating good adaptation. The ability of firms to respond to climate risks depends on factors that can be shaped through policy intervention. Findings show that financial barriers are a key reason why firms resort to reactive coping mechanisms, while general business support, access to information technology and adaptation assistance encourages sustainable adaptation responses.UK Government’s Department for International Development (DfID)Financial support from the Grantham Foundation for the Protection of the Environment, and the UK Economic and Social Research Council (ESRC) through the Centre for Climate Change Economics and Polic

Deficient histone H3 propionylation by BRPF1-KAT6 complexes in neurodevelopmental disorders and cancer

Lysine acetyltransferase 6A (KAT6A) and its paralog KAT6B form stoichiometric complexes with bromodomain- and PHD finger-containing protein 1 (BRPF1) for acetylation of histone H3 at lysine 23 (H3K23). We report that these complexes also catalyze H3K23 propionylation in vitro and in vivo. Immunofluorescence microscopy and ATAC-See revealed the association of this modification with active chromatin. Brpf1 deletion obliterates the acylation in mouse embryos and fibroblasts. Moreover, we identify BRPF1 variants in 12 previously unidentified cases of syndromic intellectual disability and demonstrate that these cases and known BRPF1 variants impair H3K23 propionylation. Cardiac anomalies are present in a subset of the cases. H3K23 acylation is also impaired by cancer-derived somatic BRPF1 mutations. Valproate, vorinostat, propionate and butyrate promote H3K23 acylation. These results reveal the dual functionality of BRPF1-KAT6 complexes, shed light on mechanisms underlying related developmental disorders and various cancers, and suggest mutation-based therapy for medical conditions with deficient histone acylation

Genomic analyses in Cornelia de Lange Syndrome and related diagnoses: Novel candidate genes, <scp>genotype–phenotype</scp> correlations and common mechanisms

Cornelia de Lange Syndrome (CdLS) is a rare, dominantly inherited multisystem developmental disorder characterized by highly variable manifestations of growth and developmental delays, upper limb involvement, hypertrichosis, cardiac, gastrointestinal, craniofacial, and other systemic features. Pathogenic variants in genes encoding cohesin complex structural subunits and regulatory proteins (NIPBL, SMC1A, SMC3, HDAC8, and RAD21) are the major pathogenic contributors to CdLS. Heterozygous or hemizygous variants in the genes encoding these five proteins have been found to be contributory to CdLS, with variants in NIPBL accounting for the majority (&gt;60%) of cases, and the only gene identified to date that results in the severe or classic form of CdLS when mutated. Pathogenic variants in cohesin genes other than NIPBL tend to result in a less severe phenotype. Causative variants in additional genes, such as ANKRD11, EP300, AFF4, TAF1, and BRD4, can cause a CdLS‐like phenotype. The common role that these genes, and others, play as critical regulators of developmental transcriptional control has led to the conditions they cause being referred to as disorders of transcriptional regulation (or “DTRs”). Here, we report the results of a comprehensive molecular analysis in a cohort of 716 probands with typical and atypical CdLS in order to delineate the genetic contribution of causative variants in cohesin complex genes as well as novel candidate genes, genotype–phenotype correlations, and the utility of genome sequencing in understanding the mutational landscape in this population

Evidence-Based Guidelines for Cardiovascular Disease Prevention in Women

Significant advances in our knowledge about interventions to prevent cardiovascular disease (CVD) have occurred since publication of the first female-specific recommendations for preventive cardiology in 1999.1 Despite research-based gains in the treatment of CVD, it remains the leading killer of women in the United States and in most developed areas of the world.2–3 In the United States alone, more than one half million women die of CVD each year, exceeding the number of deaths in men and the next 7 causes of death in women combined. This translates into approximately 1 death every minute.2 Coronary heart disease (CHD) accounts for the majority of CVD deaths in women, disproportionately afflicts racial and ethnic minorities, and is a prime target for prevention.1–2 Because CHD is often fatal, and because nearly two thirds of women who die suddenly have no previously recognized symptoms, it is essential to prevent CHD.2 Other forms of atherosclerotic/thrombotic CVD, such as cerebrovascular disease and peripheral arterial disease, are critically important in women. Strategies known to reduce the burden of CHD may have substantial benefits for the prevention of noncoronary atherosclerosis, although they have been studied less extensively in some of these settings

An international effort towards developing standards for best practices in analysis, interpretation and reporting of clinical genome sequencing results in the CLARITY Challenge

There is tremendous potential for genome sequencing to improve clinical diagnosis and care once it becomes routinely accessible, but this will require formalizing research methods into clinical best practices in the areas of sequence data generation, analysis, interpretation and reporting. The CLARITY Challenge was designed to spur convergence in methods for diagnosing genetic disease starting from clinical case history and genome sequencing data. DNA samples were obtained from three families with heritable genetic disorders and genomic sequence data were donated by sequencing platform vendors. The challenge was to analyze and interpret these data with the goals of identifying disease-causing variants and reporting the findings in a clinically useful format. Participating contestant groups were solicited broadly, and an independent panel of judges evaluated their performance. RESULTS: A total of 30 international groups were engaged. The entries reveal a general convergence of practices on most elements of the analysis and interpretation process. However, even given this commonality of approach, only two groups identified the consensus candidate variants in all disease cases, demonstrating a need for consistent fine-tuning of the generally accepted methods. There was greater diversity of the final clinical report content and in the patient consenting process, demonstrating that these areas require additional exploration and standardization. CONCLUSIONS: The CLARITY Challenge provides a comprehensive assessment of current practices for using genome sequencing to diagnose and report genetic diseases. There is remarkable convergence in bioinformatic techniques, but medical interpretation and reporting are areas that require further development by many groups
