"This Is Who I Am": Perspectives On Economics, Policy, And Personal Identity And Culture Of Cook Inlet And Kenai River Salmon Fisheries

Thesis (M.S.) University of Alaska Fairbanks, 2013Throughout this thesis, I use a multidisciplinary approach for understanding the sustainability of the culture, livelihoods, and ecosystems in the Cook Inlet and Kenai River salmon fisheries on Alaska's Kenai Peninsula. In Chapter 1, I present a broad overview of the Cook Inlet region, its inhabitants, and the various stakeholder and user groups that access regional salmon fisheries. Chapter 1 also provides an overview of the methodology utilized in this research, as well as discuss the methods, the strengths, and weaknesses of the research as part of an evaluation of the study. In Chapter 2, I present an overview of how the Kenai River and Cook Inlet salmon fisheries are managed and regulated, including regulatory bodies and agencies and their mandated roles. Finally, the chapter concludes with a presentation of ethnographic data collected during interviews between summer of 2011 and spring of 2013. These data reveal the perspectives and attitudes of fishermen, and in terms of how they regard management, and about whether management decisions contribute to or detract from the ongoing sustainability of the regional fisheries and fish stocks. In Chapter 3, I examine some of the economically based arguments commonly made to support allocation rights between the several user groups that access the area fisheries. This chapter draws upon economic reports produced by advocacy groups and the State of Alaska, as well as utilizes a comparison of these reports by an economist from the University of Alaska Anchorage. This chapter again draws upon ethnographic research to understand perspectives of fishermen, illuminating how they interpret and develop their economic arguments for allocation. In Chapter 4, I present an ethnography detailing and describing attitudes and perspectives of fishermen as to how they perceive their personal identities relate to their fishing livelihoods. Finally, in Chapter 5 I conclude with an explanation and review of findings, as well as recommendations for future research and some personal thoughts. Throughout the thesis are pieces of my personal narrative to give the reader a more intimate understanding of this research

Important, misunderstood, and challenging: a qualitative study of nurses' and allied health professionals' perceptions of implementing self-management for patients with COPD.

Hannah ML Young,1 Lindsay D Apps,1 Samantha L Harrison,1 Vicki L Johnson-Warrington,1 Nicky Hudson,2 Sally J Singh1,3 1National Institute of Health Research CLAHRC-LNR Pulmonary Rehabilitation Research Group, University Hospitals of Leicester NHS Trust, 2School of Applied Social Sciences, De Montfort University, Leicester, 3Applied Research Centre in Health and Lifestyle Interventions, Coventry University, Coventry, UK Background: In light of the growing burden of COPD, there is increasing focus on the role of self-management for this population. Currently, self-management varies widely. Little is known either about nurses’ and allied health professionals’ (AHPs’) understanding and provision of self-management in clinical practice. This study explores nurses’ and AHPs’ understanding and implementation of supported COPD self-management within routine clinical practice. Materials and methods: Nurses and AHPs participated in face-to-face semistructured interviews to explore their understanding and provision of COPD self-management, as well as their perceptions of the challenges to providing such care. Purposive sampling was used to select participants from a range of professions working within primary, community, and secondary care settings. Three researchers independently analyzed each transcript using a thematic approach. Results: A total of 14 participants were interviewed. Nurses and AHPs viewed self-management as an important aspect of COPD care, but often misunderstood what it involved, leading to variation in practice. A number of challenges to supporting self-management were identified, which related to lack of time, lack of insight regarding training needs, and assumptions regarding patients’ perceived self-management abilities. Conclusion: Nurses and AHPs delivering self-management require clear guidance, training in the use of effective self-management skills, and education that challenges their preconceptions regarding patients. The design of health care services also needs to consider the practical barriers to COPD self-management support for the implementation of such interventions to be successful.

Public attitudes towards screening for kidney cancer: an online survey

Funder: Kidney Cancer UKFunder: The Urology FoundationAbstract: Background: Kidney cancer is often asymptomatic, leading to proposals for a screening programme. The views of the public towards introducing a new screening programme for kidney cancer are unknown. The aim of this study was to explore attitudes towards kidney cancer screening and factors influencing intention to attend a future screening programme. Methods: We conducted an online population-based survey of 1021 adults aged 45–77 years. The main outcome measure was intention to attend four possible screening tests (urine, blood, ultrasound scan, low-dose CT) as well as extended low-dose CT scans within lung cancer screening programmes. We used multivariable regression to examine the association between intention and each screening test. Results: Most participants stated that they would be ‘very likely’ or ‘likely’ to undergo each of the screening tests [urine test: n = 961 (94.1%); blood test: n = 922 (90.3%); ultrasound: n = 914 (89.5%); low-dose CT: n = 804 (78.8%); lung CT: n = 962 (95.2%)]. Greater intention to attend was associated with higher general cancer worry and less perceived burden/inconvenience about the screening tests. Less worry about the screening test was also associated with higher intention to attend, but only in those with low general cancer worry (cancer worry scale ≤ 5). Compared with intention to take up screening with a urine test, participants were half as likely to report that they intended to undergo blood [OR 0.56 (0.43–0.73)] or ultrasound [OR 0.50 (0.38–0.67)] testing, and half as likely again to report that they intended to take part in a screening programme featuring a low dose CT scan for kidney cancer screening alone [OR 0.19 (0.14–0.27)]. Conclusion: Participants in this study expressed high levels of intention to accept an invitation to screening for kidney cancer, both within a kidney cancer specific screening programme and in conjunction with lung cancer screening. The choice of screening test is likely to influence uptake. Together these findings support on-going research into kidney cancer screening tests and the potential for combining kidney cancer screening with existing or new screening programmes

The development and pilot testing of the Self-management Programme of Activity, Coping and Education for Chronic Obstructive Pulmonary Disease (SPACE for COPD)

Purpose: There is no independent standardized self-management approach available for chronic obstructive pulmonary disease (COPD). The aim of this project was to develop and test a novel self-management manual for individuals with COPD. Patients: Participants with a confirmed diagnosis of COPD were recruited from primary care. Methods: A novel self-management manual was developed with health care professionals and patients. Five focus groups were conducted with individuals with COPD (N = 24) during development to confirm and enhance the content of the prototype manual. The Self-management Programme of Activity, Coping and Education for Chronic Obstructive Pulmonary Disease (SPACE for COPD) manual was developed as the focus of a comprehensive self-management approach facilitated by health care professionals. Preference for delivery was initial face-to-face consultation with telephone follow-up. The SPACE for COPD manual was piloted with 37 participants in primary care. Outcome measures included the Self-Report Chronic Respiratory Questionnaire, Incremental Shuttle Walk Test, and Endurance Shuttle Walking Test (ESWT); measurements were taken at baseline and 6 weeks. Results: The pilot study observed statistically significant improvements for the dyspnea domain of the Self-Report Chronic Respiratory Questionnaire and ESWT. Dyspnea showed a mean change of 0.67 (95% confidence interval 0.23–1.11, P = 0.005). ESWT score increased by 302.25 seconds (95% confidence interval 161.47–443.03, P < 0.001). Conclusion: This article describes the development and delivery of a novel self-management approach for COPD. The program, incorporating the SPACE for COPD manual, appears to provoke important changes in exercise capacity and breathlessness for individuals with COPD managed in primary care

Genome-wide analysis reveals no evidence of trans chromosomal regulation of mammalian immune development.

It has been proposed that interactions between mammalian chromosomes, or transchromosomal interactions (also known as kissing chromosomes), regulate gene expression and cell fate determination. Here we aimed to identify novel transchromosomal interactions in immune cells by high-resolution genome-wide chromosome conformation capture. Although we readily identified stable interactions in cis, and also between centromeres and telomeres on different chromosomes, surprisingly we identified no gene regulatory transchromosomal interactions in either mouse or human cells, including previously described interactions. We suggest that advances in the chromosome conformation capture technique and the unbiased nature of this approach allow more reliable capture of interactions between chromosomes than previous methods. Overall our findings suggest that stable transchromosomal interactions that regulate gene expression are not present in mammalian immune cells and that lineage identity is governed by cis, not trans chromosomal interactions

Acceptability and potential impact on uptake of using different risk stratification approaches to determine eligibility for screening: A population‐based survey

Funder: Kidney Cancer UKFunder: Renal Cancer Research FundAbstract: Background: Using risk stratification approaches to determine eligibility has the potential to improve efficiency of screening. Objectives: To compare the public acceptability and potential impact on uptake of using different approaches to determine eligibility for screening. Design: An online population‐based survey of 668 adults in the UK aged 45‐79 including a series of scenarios in the context of a potential kidney cancer screening programme in which eligibility was determined by age, sex, age and sex combined, a simple risk score (age, sex, body mass index, smoking status), a complex risk score additionally incorporating family history and lifestyle, or a genetic risk score. Outcome measures: We used multi‐level ordinal logistic regression to compare acceptability and potential uptake within individuals and multivariable ordinal logistic regression differences between individuals. Results: Using sex, age and sex, or the simple risk score were less acceptable than age (P < .0001). All approaches were less acceptable to women than men. Over 70% were comfortable waiting until they were older if the complex risk score or genetics indicated a low risk. If told they were high risk, 85% would be more likely to take up screening. Being told they were low risk had no overall influence on uptake. Conclusions: Varying the starting age of screening based on estimated risk from models incorporating phenotypic or genetic risk factors would be acceptable to most individuals and may increase uptake. Patient or Public Contribution: Two members of the public contributed to the development of the survey and have commented on this paper

Lcp1 Is a Phosphotransferase Responsible for Ligating Arabinogalactan to Peptidoglycan in Mycobacterium tuberculosis

Mycobacterium tuberculosis, the etiological agent of tuberculosis (TB), has a unique cell envelope which accounts for its unusual low permeability and contributes to resistance against common antibiotics. The main structural elements of the cell wall consist of a cross-linked network of peptidoglycan (PG) in which some of the muramic acid residues are covalently attached to a complex polysaccharide, arabinogalactan (AG), via a unique α-l-rhamnopyranose–(1→3)-α-d-GlcNAc-(1→P) linker unit. While the molecular genetics associated with PG and AG biosynthetic pathways have been largely delineated, the mechanism by which these two major pathways converge has remained elusive. In Gram-positive organisms, the LytR-CpsA-Psr (LCP) family of proteins are responsible for ligating cell wall teichoic acids to peptidoglycan, through a linker unit that bears a striking resemblance to that found in mycobacterial arabinogalactan. In this study, we have identified Rv3267 as a mycobacterial LCP homolog gene that encodes a phosphotransferase which we have named Lcp1. We demonstrate that lcp1 is an essential gene required for cell viability and show that recombinant Lcp1 is capable of ligating AG to PG in a cell-free radiolabeling assay

Extreme Ultra-Violet Spectroscopy of the Lower Solar Atmosphere During Solar Flares

The extreme ultraviolet portion of the solar spectrum contains a wealth of diagnostic tools for probing the lower solar atmosphere in response to an injection of energy, particularly during the impulsive phase of solar flares. These include temperature and density sensitive line ratios, Doppler shifted emission lines and nonthermal broadening, abundance measurements, differential emission measure profiles, and continuum temperatures and energetics, among others. In this paper I shall review some of the advances made in recent years using these techniques, focusing primarily on studies that have utilized data from Hinode/EIS and SDO/EVE, while also providing some historical background and a summary of future spectroscopic instrumentation.Comment: 34 pages, 8 figures.

The affordance of compassion for animals: a filmic exploration of industrial linear rhythms

Compassion is an emotion that could be useful for improving the lives of animals within the intensive and factory farming system (IFFS). Rhythms that exist within this system play a role in making compassion difficult to realize, which formulates the research question: How do the rhythms of the IFFS shape the affordance of compassion for animals? Drawing on a cultural mode of analysis informed by Henri Lefebvre’s work on rhythms, this paper explored the rhythms of three films that focus on the treatment of animals in this system: Meat; Our Daily Bread and Never Let Me Go. Industrial linear rhythms seem to compromise the compassion offered to animals in the IFFS by manipulating the cyclical rhythms of animals and animalized bodies from birth, through life and at death. Compassion for animals and animalized bodies in the IFFS, this paper concludes, is often provided in a piecemeal and localized manner
