Accounting For The Decline in Union Membership

Since the early 50s, the percent of the workforce organized by unions has declined considerably. In the most recent decade that rate of decline has accelerated sharply. In an attempt to discover what factors can account for the overall decline and the further deterioration during the 70s, we decompose the sources of growth and decline to determine the relative importance of changes in organizing activity, success in certification elections, decertifications, and net growth due to economic causes. We find that all factors except decertifications account for a substantial part of the change. In addition, interactions between the factors are very important. A significant finding is that while organizing activity and success rates have been declining over time, the net growth (or loss) of membership due to economic causes has remained stable controlling for the aggregate level of economic activity. We argue that this finding is inconsistent with the prevailing view that the decline in the percent of the workforce organized is primarily due to the decline of the heavily unionized core industries.

Structural Changes in Unionization: 1973-1981

This paper presents a decomposition of the decline in union density into structural and within sector components using CPS data for private sector workers. We find that 58 to 68 percent of the decline in private sector unionization between 1973 and 1981 can be accounted for by structural changes in the economy, particularly in the occupational, educational and gender distribution of the workforce. This is a large impact, but we find that while structural change is important, its importance was not appreciably greate during the 1970s than during previous decades. At the same time, we find that the decline of private sector unionization within sectors has been pervasive, accounting for 32 to 42 percent of union decline. As part of this analysis we find that the decline in union density has been greater in those sectors of the economy where employment decline has been greater. This fact can help reconcile previous divergent findings on the importance of structural change.

Comparing pediatric deaths with and without hospice support

Background Although pediatric hospice care is commonly accepted as a beneficial intervention, the incremental advantage over end-of-life care delivered without engaging hospice remains unknown. The primary objective of this study was to describe differences in pediatric end-of-life care when delivered with and without hospice support, as perceived by the medical provider. Procedure A retrospective survey of medical providers was conducted in 2005 over a 2-month period at a single institution, the Helen DeVos Children's Hospital (HDVCH). Medical providers with self-determined experience in pediatric end-of-life care were asked to separately provide positive and negative comments about their experience with hospice. Additionally they were asked to describe differences between children under their supervision who died with and without hospice care. Medical provider comments and comparisons of experiences in caring for children dying with and without hospice involvement are described. Results Out of 157 responders, 43 reported positive comments about the hospice intervention. Non-medical support and location of death were the most frequently cited benefits. Nineteen responders provided negative comments about hospice; all involving feelings of lost hope, intrusion, or distrust. When asked to directly compare deaths with and without hospice support, 44 of 51 (86%) responders favored hospice. The most cited reason for preferring hospice involvement was better provision of non-medical services. Conclusions The majority of pediatric providers in this survey observed an advantage to utilizing hospice care for dying children as compared to providing end-of-life care without hospice involvement.

Extractable nitrogen and microbial community structure respond to grassland restoration regardless of historical context and soil composition.

Grasslands have a long history of invasion by exotic annuals, which may alter microbial communities and nutrient cycling through changes in litter quality and biomass turnover rates. We compared plant community composition, soil chemical and microbial community composition, potential soil respiration and nitrogen (N) turnover rates between invaded and restored plots in inland and coastal grasslands. Restoration increased microbial biomass and fungal : bacterial (F : B) ratios, but sampling season had a greater influence on the F : B ratio than did restoration. Microbial community composition assessed by phospholipid fatty acid was altered by restoration, but also varied by season and by site. Total soil carbon (C) and N and potential soil respiration did not differ between treatments, but N mineralization decreased while extractable nitrate and nitrification and N immobilization rate increased in restored compared with unrestored sites. The differences in soil chemistry and microbial community composition between unrestored and restored sites indicate that these soils are responsive, and therefore not resistant to feedbacks caused by changes in vegetation type. The resilience, or recovery, of these soils is difficult to assess in the absence of uninvaded control grasslands. However, the rapid changes in microbial and N cycling characteristics following removal of invasives in both grassland sites suggest that the soils are resilient to invasion. The lack of change in total C and N pools may provide a buffer that promotes resilience of labile pools and microbial community structure

Analysis of Droplet Train/Moving Substrate Interactions in Ink-Jetting Processes

Ink-jetting technology has been applied to several processes in solid free-form fabrication (SFF) wherein droplets impinge onto a substrate to deposit the build material. Droplet impact behaviour on a surface has been the interest of many researchers; however, few studies have been undertaken to investigate the interaction of droplets with the moving substrate. This paper reports the impact behaviour of the droplets jetted at different frequencies onto a substrate moving over a range of velocities. The phenomena associated with the interaction were classified into three main regimes.Mechanical Engineerin

Ethical issues evolving from patients’ perspectives on compulsory screening for syphilis and voluntary screening for cervical cancer in Kenya

BACKGROUND: Public health aims to provide universal safety and progressive opportunities to populations to realise their highest level of health through prevention of disease, its progression or transmission. Screening asymptomatic individuals to detect early unapparent conditions is an important public health intervention strategy. It may be designed to be compulsory or voluntary depending on the epidemiological characteristics of the disease. Integrated screening, including for both syphilis and cancer of the cervix, is a core component of the national reproductive health program in Kenya. Screening for syphilis is compulsory while it is voluntary for cervical cancer. Participants’ perspectives of either form of screening approach provide the necessary contextual information that clarifies mundane community concerns. METHODS: Focus group discussions with female clients screened for syphilis and cancer of the cervix were conducted to elicit their perspectives of compulsory and voluntary screening. The discussions were audiotaped, transcribed and thematic content analysis performed manually to explore emerging ethics issues. RESULTS: The results indicate that real ethical challenges exist in either of the approaches. Also, participants were more concerned about the benefits of the procedure and whether their dignity is respected than the compulsoriness of screening per se. The implication is for the policy makers to clarify in the guidelines how to manage ethical challenges, while at the operational level, providers need to be judicious to minimize potential harms participants and families when screening for disease in women. CONCLUSIONS: The context for mounting screening as a public health intervention and attendant ethical issues may be more complex than hitherto perceived. Interpreting emerging ethics issues in screening requires more nuanced considerations of individuals’ contextual experiences since these may be contradictory to the policy position. In considering mounting screening for Syphilis and cervical cancer as a public heal intervention, the community interests and perspectives should be inculcated into the program. Population lack of information on procedures may influence adversely the demand for screening services by the individuals at risk or the community as a collective agent

Subjective wellbeing in people living with dementia: exploring processes of multiple object handling sessions in a museum setting.

Background: Dementia care guidance highlights the importance of supporting people living with dementia to access engaging and meaningful activities to promote their quality of life. There is a growing evidence base for the efficacy of heritage settings and arts-based interventions to provide social prescribing opportunities to help support wellbeing in this population. This study extended previous research and explored the potential processes underlying this effect in multiple small group object handling sessions in a museum setting. Methods: A mixed-methods design was used comprising a measure of subjective wellbeing and thematic analysis to explore in-the-moment session content across multiple sessions. Four people with dementia participated in three, one-hour group object handling sessions led by two facilitators. Results: Pre-post wellbeing scores showed increases after each session though this was largely not significant. Qualitative findings provided more compelling results, however, and identified four key themes: facilitating, interest in exploring objects, active participation, and group collaboration; interpretations were made around the dynamic interaction of themes and subthemes over the course of three sessions. Conclusions: This is the first study we are aware of that has taken an in-depth look at multiple museum-based group object handling sessions for people living with dementia. Findings offer ways to optimise object handling sessions for people with dementia by providing in-depth information about the processes involved across multiple object handling sessions facilitated by museum/heritage professionals in a museum setting. This has useful implications for community-based activities as part of dementia care planning and public health programming. The study contributes to a deeper understanding and elucidates the processes that enhance wellbeing for this population who participate in such sessions. It also helps to develop further theoretical understanding about why these types of activities are helpful in community-based dementia care. Limitations and implications for future research are discussed

GRIDCC: Real-time workflow system

The Grid is a concept which allows the sharing of resources between distributed communities, allowing each to progress towards potentially different goals. As adoption of the Grid increases so are the activities that people wish to conduct through it. The GRIDCC project is a European Union funded project addressing the issues of integrating instruments into the Grid. This increases the requirement of workflows and Quality of Service upon these workflows as many of these instruments have real-time requirements. In this paper we present the workflow management service within the GRIDCC project which is tasked with optimising the workflows and ensuring that they meet the pre-defined QoS requirements specified upon them
