Baryogenesis Constraints on the Minimal Supersymmetric Model

Requirement that the vacuum expectation values of Higgs fields immediately after the phase transition be large enough imposes constraints upon the parameters of the minimal supersymmetric model. In particular, one obtains the upper bound on the lighter CP-even Higgs mass and the soft supersymmetry breaking scale for different values of the top quark mass.Comment: 9 pages (3 figures), LATEX, BUHEP-92-

Preventing Domestic Abuse for Children and Young People (PEACH): A Mixed Knowledge Scoping Review

Background: A range of interventions that aim to prevent domestic abuse has been developed for children and young people in the general population. While these have been widely implemented, few have been rigorously evaluated. This study aimed to discover what was known about these interventions for children and what worked for whom in which settings. Review methods: This mixed knowledge review was informed by realist principles and comprised four overlapping phases: an online mapping survey to identify current provision; a systematic review of the existing literature; a review of the UK ‘grey’ literature; and consultation with young people and experts. Information from these four sources of evidence informed analysis of costs and benefits. Results: The evidence for interventions achieving changes in knowledge and attitudes was stronger than that for behavioural change. Shifting social norms in the peer group emerged as a key mechanism of change. Media campaigns act to influence the wider social climate within which more targeted interventions are received, and they are also a source for programme materials. While most interventions are delivered in secondary schools, they are increasingly targeted at younger children. The review emphasised the importance of a school’s ‘readiness’ to introduce preventative interventions which need to be supported across all aspects of school life. Involving young people in the design and delivery of programmes increases authenticity and this emerged as a key ingredient in achieving impact. Longer interventions delivered by appropriately trained staff appeared likely to be more effective. Teachers emerged as well placed to embed interventions in schools but they require training and support from those with specialist knowledge in domestic abuse. There was evidence that small groups of students who were at higher risk might have accounted for some results regarding effectiveness and that programme effectiveness may vary for certain subgroups. Increasingly, boys are being identified as a target for change. The study identified a need for interventions for disabled children and children and young people from black, Asian, minority ethnic and refugee groups and a particular lack of materials designed for lesbian, gay, bisexual and transgender young people. Limitations: Very little evidence was identified on costs and cost-effectiveness. Few studies showed an effect at the level of significance set for the review. Where it did exist, the effect size was small, except in respect of improved knowledge. The inability to calculate a response rate for the mapping survey, which used a snowballing approach, limits the ability to generalise from it. Conclusions: While it is appropriate to continue to deliver interventions to whole populations of children and young people, effectiveness appeared to be influenced by high-risk children and young people, who should be directed to additional support. Programmes also need to make provision to manage any resulting disclosures. Interventions appear to be context specific, and so those already being widely delivered in the UK and which are likely to be acceptable should be robustly tested.

The National Dialogue on the Quadrennial Homeland Security Review

Six years after its creation, the Department of Homeland Security (DHS) undertook the first Quadrennial Homeland Security Review (QHSR) to inform the design and implementation of actions to ensure the safety of the United States and its citizens. This review, mandated by the Implementing the 9/11 Commission Recommendations Act of 2007, represents the first comprehensive examination of the homeland security strategy of the nation. The QHSR includes recommendations addressing the long-term strategy and priorities of the nation for homeland security and guidance on the programs, assets, capabilities, budget, policies, and authorities of the department.Rather than set policy internally and implement it in a top-down fashion, DHS undertook the QHSR in a new and innovative way by engaging tens of thousands of stakeholders and soliciting their ideas and comments at the outset of the process. Through a series of three-week-long, web-based discussions, stakeholders reviewed materials developed by DHS study groups, submitted and discussed their own ideas and priorities, and rated or "tagged" others' feedback to surface the most relevant ideas and important themes deserving further consideration.Key FindingsThe recommendations included: (1) DHS should enhance its capacity for coordinating stakeholder engagement and consultation efforts across its component agencies, (2) DHS and other agencies should create special procurement and contracting guidance for acquisitions that involve creating or hosting such web-based engagement platforms as the National Dialogue, and (3) DHS should begin future stakeholder engagements by crafting quantitative metrics or indicators to measure such outcomes as transparency, community-building, and capacity

Pedagogical Education Practices in Communication Sciences and Disorders PhD Programs: A Pilot Study

The purpose of this study was two-fold: (1) to ascertain how research doctoral programs in Communication Sciences and Disorders (CSD) characterize their own efforts to educate research doctoral students about teaching at the college/university level; and (2) whether and how programs introduce the “scholarship of teaching and learning” (SoTL) to PhD students. PhD program directors (N=69) were emailed a survey for descriptions of university teaching instruction and SoTL activities, with a 27.5% return rate (n=19). Quantitative and qualitative analyses were used. Identified themes included, “course or seminar”, “experiential” and “required”. One hundred per cent of respondents offer teaching experiences and 58% require student participation. Sixty-three per cent offer a teaching course while 42% require the course. It is unclear from the current data whether CSD PhD students are exposed to SoTL. Given the robust, cross-disciplinary literature on teaching and learning, the time may be right for a discussion on including teaching education and SoTL in CSD PhD programs

Autoethnography in occupational science: me, we or they?

Studies of engagement in occupation have involved small group of individuals (Carin-Levy and Jones, 2007), ‘they’ or the occupational scientist/therapist themselves, (Taylor, 2008), ‘me’. My PhD research into “creative writing as an occupation” proposes an integrated approach combining autoethnography with collaborative group exploration of narratives to gain the perspective of the ‘we’. The exploration of an occupation by those who participate in it, including one who has a perspective as an occupational therapist will contribute to a deep understanding of the range of personal and sociocultural meanings (Creek, 2010) and will seek to frame the findings in occupational terms. This approach steps into a wider debate about ‘Heartful’ autoethnography, where evocative narratives ‘create the effect of reality’ (Ellis, 1999, p. 669) versus analytic autoethnography, where the researcher, a member of the research group has the specific aim of developing theoretical understanding (Anderson, 2006). Ellis and Bochner (2006) challenge the need for this analytical shift arguing that theorising or generalizing from autoethnography by using traditional analysis negates the way stories work. Through framing questions in occupational terms the narrative stories gathered will both speak for themselves and highlight occupational experience in a way that is immediately relatable to practising therapists.

Psychosocial and emotional morbidities after a diagnosis of cancer: Qualitative evidence from healthcare professional cancer patients

This inquiry aimed to; (1) examine the psychosocial and emotional sequelae associated with cancer patient-hood experience in healthcare professionals (HCPs) in Uganda, (2) generate evidence to inform clinical and nursing practice about the needs of HCP patients with cancer. This was a qualitative phenomenological study. The study was conducted among HCP cancer patients and survivors recruited from oncology and palliative care settings in Uganda. Data were collected via audio-taped, face-to-face or telephone open-ended interviews. Interviews were transcribed verbatim. Thematic analysis was used. Eight HCP cancer patients and survivors participated in the study. Their mean age was 56 years, range 29-85 years. Three major themes emerged: (1) From a healthcare provider to a patient, (2) Socioeconomic challenges, and (3) Coping and support strategies. [Abstract copyright: © 2022 The Authors.

The complexities of 'otherness': reflections on embodiment of a young White British woman engaged in cross-generation research involving older people in Indonesia

This article has been made available through the Brunel Open Access Publishing Fund.If interviews are to be considered embodied experiences, than the potential influence of the embodied researcher must be explored. A focus on specific attributes such as age or ethnicity belies the complex and negotiated space that both researcher and participant inhabit simultaneously. Drawing on empirical research with stroke survivors in an ethnically mixed area of Indonesia, this paper highlights the importance of considering embodiment as a specific methodological concern. Three specific interactions are described and analysed, illustrating the active nature of the embodied researcher in narrative production and development. The intersectionality of embodied features is evident, alongside their fluctuating influence in time and place. These interactions draw attention to the need to consider the researcher within the interview process and the subsequent analysis and presentation of narrative findings. The paper concludes with a reinforcement of the importance of ongoing and meaningful reflexivity in research, a need to consider the researcher as the other participant, and specifically a call to engage with and present the dynamic nature of embodiment

The Quark/Antiquark Asymmetry of the Nucleon Sea

Although the distributions of sea quarks and antiquarks generated by leading-twist QCD evolution through gluon splitting $g \rightarrow \bar q q$ are necessarily CP symmetric, the distributions of nonvalence quarks and antiquarks which are intrinsic to the nucleon's bound state wavefunction need not be identical. In this paper we investigate the sea quark/antiquark asymmetries in the nucleon wavefunction which are generated by a light-cone model of energetically-favored meson-baryon fluctuations. The model predicts striking quark/antiquark asymmetries in the momentum and helicity distributions for the down and strange contributions to the proton structure function: the intrinsic $d$ and $s$ quarks in the proton sea are predicted to be negatively polarized, whereas the intrinsic $\bar d$ and $\bar s$ antiquarks give zero contributions to the proton spin. Such a picture is supported by experimental phenomena related to the proton spin problem and the violation of the Ellis-Jaffe sum rule. The light-cone meson-baryon fluctuation model also suggests a structured momentum distribution asymmetry for strange quarks and antiquarks which could be relevant to an outstanding conflict between two different determinations of the strange quark sea in the nucleon. The model predicts an excess of intrinsic $d \bar d$ pairs over $u \bar u$ pairs, as supported by the Gottfried sum rule violation. We also predict that the intrinsic charm and anticharm helicity and momentum distributions are not identical.Comment: LaTex 18 pages, 4 figures. To obtain a copy, send e-mail to [email protected]

The effect of SU-8 patterned surfaces on the response of the quartz crystal microbalance

In this work we present data showing the effect of patterning layers of SU-8 photoresist on a quartz crystal microbalance (QCM) and subsequent chemical treatment to increase their hydrophobicity. Patterns with 5 mu m diameter pillars spaced every 10 mu m have been fabricated with heights of 3, 5 and 10 mu m in addition to equivalent thickness flat layers. Contact angle measurements have been made before and after the hydrophobic chemical treatment. The change in resonant frequency of the QCM has been investigated as the surfaces were submerged in solutions of water/PEG with changing viscosity-density product
