Models Needed to Assist in the Development of a National Fiber Supply Strategy for the 21st Century: Report of a Workshop

This discussion paper reports on a Workshop on Wood Fiber Supply Modeling held October 3-4, 1996 in Washington, DC. The purpose of this discussion paper is to provide an overview of some of the modeling work being done related to timber supply modeling and some of the issues related to the more useful application of wood fiber supply and projections models. This paper includes brief presentations of three commonly used long-term timber projections and forecasting models: the Timber Assessment Market Model (TAMM) of the Forest Service; the Cintrafor Global Trade Model (CGTM) of the University of Washington; and the Timber Supply Model (TSM) of Resources for the Future. Also, issues related to the useful of the models are addressed as well as a discussion of some applications of other timber or fiber projection models. The usefulness of the models are addressed from both a technical perspective and also from the perspective of their usefulness to various model users.

The Role of Media Specialists with Respect to Instructional Technology in an Urban School District in Georgia

In the absence of a Georgia Educator Certificate in instructional technology, and of state-wide staffing requirements for instructional technology specialists, media specialists may be playing an increasingly larger role in instructional technology support and focusing less on other vital media specialist responsibilities. A deeper understanding of the role of media specialists with respect to instructional technology may provide insight into determining a need for instructional technology certification and support in Georgia schools. The purpose of this quantitative survey study was to examine the role of media specialists with respect to instructional technology in an urban school district in Georgia. Practicing media specialists’ perceived use, and perceived ideal use, of instructional technology specialist and media specialist job competencies were examined. The data revealed an overall difference among the four dependent variables (a) perceived current use of media specialist competencies, (b) perceived ideal use of media specialist competencies, (c) perceived current use of instructional technology specialist competencies, and (d) perceived ideal use of instructional technology specialist competencies. Within-subjects contrasts revealed significant pairwise differences among all the variables except the comparison of the use of media specialist competencies and the use of instructional technology specialist competencies. These findings suggest that in the absence of consistently staffed, certified instructional technology specialists, media specialists are playing an increasingly larger role in instructional technology support and focusing less on other essential media specialist roles and responsibilities

Effectiveness and costs of a vocational advice service to improve work outcomes in patients with musculoskeletal pain in primary care: a cluster randomised trial (SWAP trial ISRCTN 52269669)

Musculoskeletal pain is a common cause of work absence and early intervention is advocated to prevent the adverse health and economic consequences of longer term absence. This cluster randomised controlled trial investigated the effect of introducing what was termed a vocational advice service into primary care to provide occupational advice. Six general practices were randomised, patients were eligible if they were consulting their general practitioner (GP) with musculoskeletal pain, were employed and struggling at work or absent from work <6 months. Practices in the intervention arm could refer patients to a vocational advisor embedded within the practice providing a case managed stepwise intervention addressing obstacles to working. The primary outcome was number of days off work, over 4 months. Participants in the intervention arm (n=158) had fewer days work absence compared to the control arm (n=180) (mean 9.3 (SD 21·7) versus 14·4 (SD 27·7)) days, Incidence Rate Ratio (IRR) 0·51 (95% Confidence Interval 0·26, 0·99), p=0·048). The net societal benefit of the intervention compared with best care was £733: £748 gain (work absence) versus £15 loss (health care costs). The addition of a vocational advice service to best current primary care for patients consulting with musculoskeletal pain led to reduced absence and cost savings for society. If a similar early intervention to the one tested in this trial was implemented widely, it could potentially reduce days absent over 12 months by 16%, equating to an overall societal cost-saving of about £500 million (US $6 billion), and requiring an investment of only £10 million

Job anxiety, work-related psychological illness and workplace performance

This paper uses matched employee-employer data from the British Workplace Employment Relations Survey (WERS) to examine the relationship between employee psychological health and workplace performance in 2004 and 2011. Using two measures of work-related psychological health – namely employee-reported job anxiety and manager-reported workforce stress, depression and anxiety – we find a positive relationship between psychological ill-health and absence, but not quits. The association between psychological ill-health and labour productivity is less clear, with estimates sensitive to sector, time period and the measure of psychological health. The 2004-2011 panel is further used to explore the extent to which change in psychological health is related to change in performance

Development of the Workplace Health Savings Calculator:A practical tool to measure economic impact from reduced absenteeism and staff turnover in workplace health promotion Public Health

Background: Workplace health promotion is focussed on improving the health and wellbeing of workers. Although quantifiable effectiveness and economic evidence is variable, workplace health promotion is recognised by both government and business stakeholders as potentially beneficial for worker health and economic advantage. Despite the current debate on whether conclusive positive outcomes exist, governments are investing, and business engagement is necessary for value to be realised. Practical tools are needed to assist decision makers in developing the business case for workplace health promotion programs. Our primary objective was to develop an evidence-based, simple and easy-to-use resource (calculator) for Australian employers interested in workplace health investment figures. Results: Three phases were undertaken to develop the calculator. First, evidence from a literature review located appropriate effectiveness measures. Second, a review of employer-facilitated programs aimed at improving the health and wellbeing of employees was utilised to identify change estimates surrounding these measures, and third, currently available online evaluation tools and models were investigated. We present a simple web-based calculator for use by employers who wish to estimate potential annual savings associated with implementing a successful workplace health promotion program. The calculator uses effectiveness measures (absenteeism and staff turnover rates) and change estimates sourced from 55 case studies to generate the annual savings an employer may potentially gain. Australian wage statistics were used to calculate replacement costs due to staff turnover. The calculator was named the Workplace Health Savings Calculator and adapted and reproduced on the Healthy Workers web portal by the Australian Commonwealth Government Department of Health and Ageing. Conclusion: The Workplace Health Savings Calculator is a simple online business tool that aims to engage employers and to assist participation, development and implementation of workplace health promotion programs

Diseño y validación mediante la Teoría de Respuesta al Ítem del Instrumento para Evaluar Capital Psicológico en las Organizaciones IPSICAP

16 p.El constructo “capital psicológico”, creado por Fred Luthans, se define como un estado de desarrollo psicológico positivo del ser humano, que lo caracteriza por (a) tener confianza (autoeficacia) para realizar los esfuerzos que sean necesarios con el fin de alcanzar el éxito en tareas retadoras; (b) hacer atribuciones de causalidad positivas (optimismo) acerca de los sucesos presentes y futuros; (c) perseverar en el logro de los objetivos y, cuando sea necesario, redireccionar los caminos para alcanzarlos (esperanza) de manera exitosa; y (d) al ser blanco de los problemas y la adversidad, mantenerse en pie, volver a comenzar e ir más allá (resiliencia) para lograr el éxito (Luthans, Youssef & Avolio, 2007a, 2007b). Este constructo ha surgido a partir de investigación empírica dentro del comportamiento organizacional positivo, y se ha identificado como un factor nuclear (core factor) de segundo orden (Avey, Patera & West, 2006). Específicamente, las bases teóricas de sus cuatro componentes tienen origen en la psicología clínica, y la aplicación al contexto laboral ha sido realizada principalmente por Fred Luthans, Carolyn Youssef y Bruce Avolio (Luthans & Avolio, 2003; Luthans, Avolio, Walumbwa & Li, 2005); aunque también ha sido trabajado por el grupo de investigación WoNT-Work and Organizational Network, dirigido por Marisa Salanova, en España.Introducción Método Resultados Discusión Referencia

Return on investment of public health interventions : a systematic review

BACKGROUND: Public sector austerity measures in many high-income countries mean that public health budgets are reducing year on year. To help inform the potential impact of these proposed disinvestments in public health, we set out to determine the return on investment (ROI) from a range of existing public health interventions. METHODS: We conducted systematic searches on all relevant databases (including MEDLINE; EMBASE; CINAHL; AMED; PubMed, Cochrane and Scopus) to identify studies that calculated a ROI or cost-benefit ratio (CBR) for public health interventions in high-income countries. RESULTS: We identified 2957 titles, and included 52 studies. The median ROI for public health interventions was 14.3 to 1, and median CBR was 8.3. The median ROI for all 29 local public health interventions was 4.1 to 1, and median CBR was 10.3. Even larger benefits were reported in 28 studies analysing nationwide public health interventions; the median ROI was 27.2, and median CBR was 17.5. CONCLUSIONS: This systematic review suggests that local and national public health interventions are highly cost-saving. Cuts to public health budgets in high income countries therefore represent a false economy, and are likely to generate billions of pounds of additional costs to health services and the wider economy

Cost Burden of Illness for Hepatitis C Patients with Employer-Sponsored Health Insurance

The disease burden of hepatitis C virus (HCV) is expected to more than double in the next two decades. Currently, there is very little information about the costs of HCV treatment for employers who pay for treatment and health plans that cover HCV patients. This study reports the medical costs of HCV for workers with health insurance. A retrospective claims data design was used for this study. A sample of HCV patients with health insurance was drawn from the inpatient, outpatient, and enrollment files of the MEDSTAT Group's MarketScan family of databases for 1993-1998. Patients were grouped into cohorts and studied for up to 2 years before and after HCV diagnosis. Sample size varies according to length of follow-up, peaking at 3,077 patients enrolled for at least 6 months. In the first year following HCV diagnosis, average payments for HCV patients ($10,925) were almost six times as high as payments for all patients in the MarketScan database ($1,186). Doctors are encouraged to test high-risk patients to find HCV patients earlier in the course of their disease and to better manage their care in order to avoid unnecessary illness and expenses for this disease.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/63140/1/109350702320229195.pd

Truck drivers' perceptions on wearable devices and health promotion:A qualitative study

Professional truck drivers, as other shift workers, have been identified as a high-risk group for various health conditions including cardiovascular disease, obesity, diabetes, sleep apnoea and stress. Mobile health technologies can potentially improve the health and wellbeing of people with a sedentary lifestyle such as truck drivers. Yet, only a few studies on health promotion interventions related to mobile health technologies for truck drivers have been conducted. We aimed to explore professional truck drivers views on health promotion delivered via mobile health technologies such as wearable devices.We conducted a phenomenological qualitative study, consisting of four semi-structured focus groups with 34 full-time professional truck drivers in the UK. The focus groups were audio-taped, transcribed verbatim and analysed using thematic content analysis. We discussed drivers perceptions of their health, lifestyle and work environment, and their past experience and expectations from mobile health technologies.The participants viewed their lifestyle as unhealthy and were aware of possible consequences. They expressed the need and wish to change their lifestyle, yet perceived it as an inherent, unavoidable outcome of their occupation. Current health improvement initiatives were not always aligned with their working conditions. The participants were generally willing to use mobile health technologies such as wearable devices, as a preventive measure to avoid prospect morbidity, particularly cardiovascular diseases. They were ambivalent about privacy and the risk of their employers monitoring their clinical data.Wearable devices may offer new possibilities for improving the health and wellbeing of truck drivers. Drivers were aware of their unhealthy lifestyle. They were interested in changing their lifestyle and health. Drivers raised concerns regarding being continuously monitored by their employer. Health improvement initiatives should be aligned with the unique working conditions of truck drivers. Future research is needed to examine the impact of wearable devices on improving the health and wellbeing of professional drivers
