Stories of female special school headteachers and their experience of headship: an interpretative phenomenological analysis
Leadership positions in special schools are becoming increasingly difficult to
fill and there is a significant gap in the literature on special school leadership
in general. This gap in the research includes a focus on the life stories of
female headteachers in these settings and situated within a constructivist
paradigm. Taking a narrative approach, this study will explore the life stories
of female special school headteachers, building on an understanding of their
leadership journey in order to potentially act as an inspiration to others.
Detailing different aspects of the special school headteachersâ experiences,
the themes highlighted the complexity of the womenâs impressions of special
school headship, the heterogeneity among the special school headteacher
stories and the importance of critical reflection within their journey.
Unstructured interviews were conducted with six participants. All interview
transcripts were analysed using Interpretative Phenomenological Analysis
(IPA). Three subordinate themes emerged from the data: âmanaging
constraintâ, âmotivating forcesâ and âperceptions of special school headship
and the futureâ.
Drawing on Giddensâ theory of social forces and his belief about the primacy
of human knowledgeability over social forces, and also Margaret Archerâs
theory of reflexivity as an intercessor between structural forces and human
agency, this thesis proposes three types of special school headteacher: âthe
strategic and decisive leaderâ, âthe values-orientated professionalâ and âthe
person-centred educatorâ. These ideal types illustrate the heterogeneous
ways in which a small sample of women special school headteachers had
reflected on, positioned themselves towards and navigated their way through
the career challenges in special education. This typology together with the
nuanced analysis advanced throughout this thesis offers a unique
contribution to knowledge. The varying inferences for special school practice
4
and research were discussed and I conclude by arguing that the underrepresentation of women in special school headship is a complex situation,
and the stories of special school headteachers merit a place at the centre of
our theorising and understanding of it.
The findings reported in this thesis may be of interest to potential special
school headteacher aspirants, as well as those tasked with identifying and
training future special school leaders

Solutions for Recovering and Sustaining the Bounty of the Ocean Combining Fishery Reforms, Rights-Based Fisheries Management, and Marine Reserves
Food security, economic opportunities, and other benefits provided by a healthy ocean are in jeopardy because of years of overexploitation of many fisheries, and the challenges will intensify in many locales as climate and the environment continue to change. The good news is that solutions are gaining traction. Mandates to end overfishing that use scientifically determined catch limits and rights-based approaches to fishery management have produced impressive results in ending overfishing and recovering depleted stocks. Similarly, spatial protections, such as fully protected marine reserves, are increasing the diversity, size, and abundance of species within reserves; some of that bounty reaches fished areas outside of them. We review the effects of combining catch limits, rights-based fisheries approaches, and establishment of marine reserves and discuss additional advantages of these combined solutions in securing sustainable and profitable fisheries, community goals, and healthy ecosystems. This paper highlights the contribution of emerging science-based solutions and the steps needed to replicate and scale these successes. Triple-wins for the environment, the economy, and society can be achieved through integrated fisheries management and protection as conscious steps toward reversing the current degradation of our oceanâs living resources.This manuscript is based on a keynote lecture given by Jane Lubchenco at One Planet, One Ocean: The 2nd International Ocean Research Conference, Barcelona, Spain, November 17â21, 2014.

A large-scale genome-wide association study meta-analysis of cannabis use disorder
Summary Background Variation in liability to cannabis use disorder has a strong genetic component (estimated twin and family heritability about 50â70%) and is associated with negative outcomes, including increased risk of psychopathology. The aim of the study was to conduct a large genome-wide association study (GWAS) to identify novel genetic variants associated with cannabis use disorder. Methods To conduct this GWAS meta-analysis of cannabis use disorder and identify associations with genetic loci, we used samples from the Psychiatric Genomics Consortium Substance Use Disorders working group, iPSYCH, and deCODE (20â916 case samples, 363â116 control samples in total), contrasting cannabis use disorder cases with controls. To examine the genetic overlap between cannabis use disorder and 22 traits of interest (chosen because of previously published phenotypic correlations [eg, psychiatric disorders] or hypothesised associations [eg, chronotype] with cannabis use disorder), we used linkage disequilibrium score regression to calculate genetic correlations. Findings We identified two genome-wide significant loci: a novel chromosome 7 locus (FOXP2, lead single-nucleotide polymorphism [SNP] rs7783012; odds ratio [OR] 1·11, 95% CI 1·07â1·15, p=1·84âĂâ10â9) and the previously identified chromosome 8 locus (near CHRNA2 and EPHX2, lead SNP rs4732724; OR 0·89, 95% CI 0·86â0·93, p=6·46âĂâ10â9). Cannabis use disorder and cannabis use were genetically correlated (rg 0·50, p=1·50âĂâ10â21), but they showed significantly different genetic correlations with 12 of the 22 traits we tested, suggesting at least partially different genetic underpinnings of cannabis use and cannabis use disorder. Cannabis use disorder was positively genetically correlated with other psychopathology, including ADHD, major depression, and schizophrenia. Interpretation These findings support the theory that cannabis use disorder has shared genetic liability with other psychopathology, and there is a distinction between genetic liability to cannabis use and cannabis use disorder.

Shared genetic risk between eating disorder- and substance-use-related phenotypes:Evidence from genome-wide association studies
First published: 16 February 202
Multiple novel prostate cancer susceptibility signals identified by fine-mapping of known risk loci among Europeans
Genome-wide association studies (GWAS) have identified numerous common prostate cancer (PrCa) susceptibility loci. We have
fine-mapped 64 GWAS regions known at the conclusion of the iCOGS study using large-scale genotyping and imputation in
25 723 PrCa cases and 26 274 controls of European ancestry. We detected evidence for multiple independent signals at 16
regions, 12 of which contained additional newly identified significant associations. A single signal comprising a spectrum of
correlated variation was observed at 39 regions; 35 of which are now described by a novel more significantly associated lead SNP,
while the originally reported variant remained as the lead SNP only in 4 regions. We also confirmed two association signals in
Europeans that had been previously reported only in East-Asian GWAS. Based on statistical evidence and linkage disequilibrium
(LD) structure, we have curated and narrowed down the list of the most likely candidate causal variants for each region.
Functional annotation using data from ENCODE filtered for PrCa cell lines and eQTL analysis demonstrated significant
enrichment for overlap with bio-features within this set. By incorporating the novel risk variants identified here alongside the
refined data for existing association signals, we estimate that these loci now explain âŒ38.9% of the familial relative risk of PrCa,
an 8.9% improvement over the previously reported GWAS tag SNPs. This suggests that a significant fraction of the heritability of
PrCa may have been hidden during the discovery phase of GWAS, in particular due to the presence of multiple independent
signals within the same regio

Transancestral GWAS of alcohol dependence reveals common genetic underpinnings with psychiatric disorders
Liability to alcohol dependence (AD) is heritable, but little is known about its complex polygenic architecture or its genetic relationship with other disorders. To discover loci associated with AD and characterize the relationship between AD and other psychiatric and behavioral outcomes, we carried out the largest genome-wide association study to date of DSM-IV-diagnosed AD. Genome-wide data on 14,904 individuals with AD and 37,944 controls from 28 case-control and family-based studies were meta-analyzed, stratified by genetic ancestry (European, n = 46,568; African, n = 6,280). Independent, genome-wide significant effects of different ADH1B variants were identified in European (rs1229984; P = 9.8 x 10(-13)) and African ancestries (rs2066702; P = 2.2 x 10(-9)). Significant genetic correlations were observed with 17 phenotypes, including schizophrenia, attention deficit-hyperactivity disorder, depression, and use of cigarettes and cannabis. The genetic underpinnings of AD only partially overlap with those for alcohol consumption, underscoring the genetic distinction between pathological and nonpathological drinking behaviors.Peer reviewe
Influence of substrate supply to the colon on bowel habit and the amount and composition of stool output
The current dietary recommendations aim to increase the complex carbohydrate component of the diet, in order to increase daily stool weight and decrease the risk of cancer of the colon and other diseases associated with the large bowel. Colonic bacteria ferment dietary carbohydrate, non-starch polysaccharide (NSP), resistant starch (RS) and other fermentable substrates delivered to the colon, stimulating colonic bacterial growth. The aim of this research was to determine to what extent colonic bacterial activity and stool output may be influenced by the supply of different types of fermentable substrate to the colon.It has been possible to isolate faecal bacteria and demonstrate that colonic bacterial activity may be altered, by dietary manipulation, according to the type and amount of fermentable substrate delivered to the colon. Whilst it has been demonstrated that stool output may be increased with an increase in the intake of fermentable substrate in the diet, this is not necessarily due to an increase in the excretion of bacteria within stool, even though colonic fermentation of substrate may be indicated. Stool output and the proportion of stool attributable to bacteria may be reduced, however, by eliminating the intake of fermentable substrate in the diet.These findings demonstrate that the bacterial component of stool is inherently controlled within certain limits and may only be altered under extreme conditions.
