Mixed-conducting oxygen permeable ceramic membranes for the carbon dioxide reforming of methane

This is the published version. Copyright 2007 Royal Society of ChemistryDue to the high economic, environmental, and safety costs associated with pure oxygen, mixed-conducting oxygen-permeable ceramic membranes are being explored as an alternative oxygen source for hydrocarbon conversion reactors. This work reports a dramatic improvement in catalyst performance when an oxygen-permeable SrFeCo0.5Ox ceramic membrane is used in conjunction with a conventional powder Pt/ZrO2 catalyst for the CO2 reforming of CH4. Experiments comparing catalyst performance with up to 2% co-fed oxygen to catalyst performance with oxygen from the ceramic membrane demonstrated a conversion three times higher with the membrane than with any amount of co-fed oxygen. The results suggest that membrane oxygen is more beneficial for catalyst activity and stability than molecular gas-phase oxygen

Mental Health and Psychosocial Functioning in Recently Separated U.S. Women Veterans: Trajectories and Bi-Directional Relationships

Prior research on the relationship between veterans’ mental health and psychosocial functioning has primarily relied on male samples. Here, we investigated prospective longitudinal relationships between mental health and psychosocial functioning in 554 female Iraq and Afghanistan War veterans who were surveyed three times between two- and seven-years following separation from service. Mixed effects modeling revealed that increasing depression and posttraumatic stress disorder (PTSD) severity predicted declines in work functioning. Increasing PTSD severity predicted declining parental functioning and worsening depression predicted a decline in relationship functioning. In turn, decreased work and intimate relationship functioning predicted increased PTSD and depression symptom severity suggesting bi-directional effects between mental health and psychosocial functioning. An examination of the effect of deployment stressors on psychosocial functioning revealed that deployment sexual harassment was the strongest predictor of decreased psychosocial functioning across all domains. Evidence for the reciprocal nature of relationships between mental health and psychosocial functioning underscore the need for treatment targeted at PTSD and depression, as well as work and relationship functioning to improve outcomes for women veterans

Managing whales at risk : how does population genetics inform marine policy and management?

Overview: In recent years, an increasing number of large whales have become entangled by crab trap lines off the U.S. Pacific coast. Wildlife managers are interested in knowing whether the whales are from threatened or endangered populations. In this lesson, students will learn how whale populations are defined, and how population genetics can be used to help inform marine policy and management.Learning Goals: Students will learn the following: • Genetic data provides information that can help researchers and resource managers identify and protect populations that are at greatest risk. • Genetically distinct populations of organisms can exist in the same area during certain periods of the year. • Knowing the status of the population to which an impacted individual whale belongs can inform how managers respond to threats

Differences between homeless and non-homeless people in a matched sample referred for mental health reasons in police custody

Introduction: Homelessness has risen across high-income countries in the last decade, and in the United Kingdom, there has been a drastic increase in people living on the streets. Due to these increases, policy responses from public services are required to address the needs of this group. The risk factors for homelessness and conditions that this group live in mean they are at elevated risk of both mental health problems and contact with the criminal justice system. Despite this, there is little previous research on the homeless in police custody. Methods: Our study used a matched sample of homeless (n = 77) and non-homeless (n = 77) individuals to examine whether there were different needs across this group and whether the responses of a criminal justice mental health service differ for this group. This study is a secondary data analysis of a more extensive study. Results: Homeless and non-homeless detainees referred to the mental health service were broadly similar. However, differences in some variables show that homeless detainees had higher rates and frequency of substance misuse as well as some suggestion of more acute immediate need. Onward referrals were lower for homeless people, and it is not clear why this is the case. In addition, for those referred contact with services over time was reduced compared to the non-homeless group. Discussion: Our findings indicate that mental health services in police custody may need adaptations to ensure homeless individuals’ higher level of need is addressed and that they receive appropriate care both during and after detention. Further quantitative and qualitative research is needed to confirm why responses differ and to assess what can be done to address this issue

Measuring IPDE-SQ personality disorder prevalence in pre-sentence and early-stage prison populations, with sub-type estimates

Understanding the prevalence and type of personality disorder within prison systems allows for the effective targeting of resources to implement strategies to alleviate symptoms, manage behaviour and attempt to reduce re-offending. This study aimed to determine the prevalence of personality disorder (PD) traits within a local urban high-turnover adult male prison with a remand/recently sentenced population in London, UK. The International Personality Disorder Examination–Screening Questionnaire (IPDE-SQ) self-administered questionnaire (ICD-10 version) was completed by 283 prisoners (42% completion rate). 77% of respondents reached the threshold for one or more PDs. The most common PD types were Paranoid PD (44.5%), Anankastic PD (40.3%), Schizoid PD (35%) and Dissocial PD (25.8%). These results confirm and extend existing knowledge regarding the prevalence of PD in prison populations into a high-turnover, urban, remand population. The stark comparison with community samples indicates that a more equitable standard of service delivery within the criminal justice system, focussing on preventive and early intervention services, is now required

Consensus on exercise reporting template (Cert): Modified delphi study

© 2016 American Physical Therapy Association. Background. Exercise interventions are often incompletely described in reports of clinical trials, hampering evaluation of results and replication and implementation into practice. Objective. The aim of this study was to develop a standardized method for reporting exercise programs in clinical trials: the Consensus on Exercise Reporting Template (CERT). Design and Methods. Using the EQUATOR Network’s methodological framework, 137 exercise experts were invited to participate in a Delphi consensus study. A list of 41 items was identified from a meta-epidemiologic study of 73 systematic reviews of exercise. For each item, participants indicated agreement on an 11-point rating scale. Consensus for item inclusion was defined a priori as greater than 70% agreement of respondents rating an item 7 or above. Three sequential rounds of anonymous online questionnaires and a Delphi workshop were used. Results. There were 57 (response rate=42%), 54 (response rate=95%), and 49 (response rate=91%) respondents to rounds 1 through 3, respectively, from 11 countries and a range of disciplines. In round 1, 2 items were excluded; 24 items reached consensus for inclusion (8 items accepted in original format), and 16 items were revised in response to participant suggestions. Of 14 items in round 2, 3 were excluded, 11 reached consensus for inclusion (4 items accepted in original format), and 7 were reworded. Sixteen items were included in round 3, and all items reached greater than 70% consensus for inclusion. Limitations. The views of included Delphi panelists may differ from those of experts who declined participation and may not fully represent the views of all exercise experts. Conclusions. The CERT, a 16-item checklist developed by an international panel of exercise experts, is designed to improve the reporting of exercise programs in all evaluative study designs and contains 7 categories: materials, provider, delivery, location, dosage, tailoring, and compliance. The CERT will encourage transparency, improve trial interpretation and replication, and facilitate implementation of effective exercise interventions into practice
