Case Study: A Comparative Analysis of Different Approaches to Fisheries Co-management in Antigua and Barbuda
Career progression of black managers
This research programme examined the factors that affect the career progression of Black managers in the United Kingdom. The research comprised two distinct but related studies. The first study was a qualitative investigation of the factors affecting the career progression of Black managers (n = 64). The main finding from the first study was that for some the achievement of high salaries and senior positions may be at the expense of one's positive Black racial identity attitudes and wellbeing. The second study was a quantitative examination of aspects revealed as important correlates of career success in study 1. Two hundred and sixty-one respondents (97 Black and 163 White respondents) across all major industry sectors participated. The results of the second study confirmed that Black managers were more disadvantaged than their White peers. The proposition that for some Black managers a 'sell out' effect occurs was supported.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

Analysis of opo cis-regulatory landscape uncovers Vsx2 requirement in early eye morphogenesis
The self-organized morphogenesis of the vertebrate optic cup entails coupling the activation of the retinal gene regulatory network to the constriction-driven infolding of the retinal epithelium. Yet the genetic mechanisms underlying this coordination remain largely unexplored. Through phylogenetic footprinting and transgenesis in zebrafish, here we examine the cis-regulatory landscape of opo, an endocytosis regulator essential for eye morphogenesis. Among the different conserved enhancers identified, we isolate a single retina-specific element (H6_10137) and show that its activity depends on binding sites for the retinal determinant Vsx2. Gain- and loss-of-function experiments and ChIP analyses reveal that Vsx2 regulates opo expression through direct binding to this retinal enhancer. Furthermore, we show that vsx2 knockdown impairs the primary optic cup folding. These data support a model by which vsx2, operating through the effector gene opo, acts as a central transcriptional node that coordinates neural retina patterning and optic cup invagination in zebrafish.info:eu-repo/semantics/publishedVersio
Black Girls Speak STEM: Counterstories of Informal and Formal Learning Experiences
This study presents the interpretations and perceptions of Black girls who participated in I AM STEM – a community-based informal science, technology, engineering, and mathematics (STEM) program. Using narrative inquiry, participants generated detailed accounts of their informal and formal STEM learning experiences. Critical race methodology informed this research to portray the dynamic and complex experiences of girls of color, whose stories have historically been silenced and misrepresented. The data sources for this qualitative study included individual interviews, student reflection journals, samples of student work, and researcher memos, which were triangulated to produce six robust counterstories. Excerpts of the counterstories are presented in this article. The major findings of this research revealed that I AM STEM ignited an interest in STEM learning through field trips and direct engagement in scientific phenomena that allowed the girls to become agentic in continuing their engagement in STEM activities throughout the year. This call to awaken the voices of Black girls to speak casts light on their experiences and challenges as STEM learners ⎯ from their perspectives. The findings confirm that when credence and counterspaces are given to Black girls, they are poised to reveal their luster toward STEM learning. This study provided a space for Black girls to reflect on their STEM learning experiences, formulate new understandings, and make connections between the informal and formal learning environments within the context of their everyday lives, thus offering a more holistic approach to STEM learning that occurs across settings and over a lifetime
A Genome-Wide Association Study of Diabetic Kidney Disease in Subjects With Type 2 Diabetes
dentification of sequence variants robustly associated with predisposition to diabetic kidney disease (DKD) has the potential to provide insights into the pathophysiological mechanisms responsible. We conducted a genome-wide association study (GWAS) of DKD in type 2 diabetes (T2D) using eight complementary dichotomous and quantitative DKD phenotypes: the principal dichotomous analysis involved 5,717 T2D subjects, 3,345 with DKD. Promising association signals were evaluated in up to 26,827 subjects with T2D (12,710 with DKD). A combined T1D+T2D GWAS was performed using complementary data available for subjects with T1D, which, with replication samples, involved up to 40,340 subjects with diabetes (18,582 with DKD). Analysis of specific DKD phenotypes identified a novel signal near GABRR1 (rs9942471, P = 4.5 x 10(-8)) associated with microalbuminuria in European T2D case subjects. However, no replication of this signal was observed in Asian subjects with T2D or in the equivalent T1D analysis. There was only limited support, in this substantially enlarged analysis, for association at previously reported DKD signals, except for those at UMOD and PRKAG2, both associated with estimated glomerular filtration rate. We conclude that, despite challenges in addressing phenotypic heterogeneity, access to increased sample sizes will continue to provide more robust inference regarding risk variant discovery for DKD.Peer reviewe
Career progression of black managers
This research programme examined the factors that affect the
career progression of Black managers in the United Kingdom.
The research comprised two distinct but related studies. The first
study was a qualitative investigation of the factors affecting the
career progression of Black managers (n = 64).
The main finding from the first study was that for some the
achievement of high salaries and senior positions may be at the
expense of one's positive Black racial identity attitudes and wellbeing.
The second study was a quantitative examination of aspects
revealed as important correlates of career success in study 1.
Two hundred and sixty-one respondents (97 Black and 163 White
respondents) across all major industry sectors participated. The
results of the second study confirmed that Black managers were
more disadvantaged than their White peers. The proposition that
for some Black managers a "sell out" effect occurs was supported
ISFM Guidelines on population management and welfare of unowned domestic cats (Felis catus)
Cats are among the most commonly kept domestic pets, and coexist with humans in a variety of different circumstances. Cats are sentient beings and, as such, humans have a responsibility for cat welfare where humans and cats coexist. Because cats reproduce efficiently, measures to control populations are frequently needed, but these should be based on ethical and humane approaches
ISFM guidelines on population management and welfare of unowned domestic cats (Felis catus)
Guidelines rationale: Cats are among the most commonly kept domestic pets, and coexist
with humans in a variety of different circumstances. Cats are sentient beings and, as such,
humans have a responsibility for cat welfare where humans and cats coexist. Because cats
reproduce efficiently, measures to control populations are frequently needed, but these should
be based on ethical and humane approaches.
Framework: These consensus guidelines from the International Society of Feline Medicine’s
Welfare Advisory Panel provide a framework for the approach to welfare and population control
measures, primarily among unowned cats and those going through a homing programme
