Sub-chronic toxicity of Senilia senilis hepatopancreas in albino Wistar mice
No full textThis study investigates the sub-chronic effects of shellfish possibly contaminated by algal toxins in albino Wistar mice. Following in-feed treatment with hepatopancreas, there were significant (p < 0.05) differences in packed cell volume, haemoglobin concentration, red blood cell count, lymphocyte count and alanine aminotransferase between the different treatment groups and control. Post mortem revealed inflammation and congestion in the gastrointestinal tract of the middle and highest dose groups. The stomach of the mice fed on the highest dose of the hepatopancreas showed severe ulcerations, leaving behind deep cavities and necrotic tissues on the glandular epithelium of the mucosal wall
The effect of treatment of clinical endometritis on reproductive performance in dairy cows
No full textThe objective of this field trial was to compare the effect of intrauterine (i.u.) antibiotic or intramuscular (i.m.) prostaglandin F2 alpha (PGF2 alpha) on time to pregnancy in dairy cows diagnosed with clinical endometritis between 20 and 33 days in milk (DIM). The case definition of endometritis was the presence of purulent uterine discharge or cervical diameter > 7.5 cm, or the presence of muco-purulent discharge after 26 DIM. There were 316 cows with endometritis from 27 farms assigned randomly within herd to receive 500 mg of cephapirin benzathine intrauterine (i.u.), 500 micrograms of cloprostenol i.m., or no treatment. The rate of resolution of clinical signs 14 d after treatment was 77% and was not affected by treatment. Reproductive performance was monitored for a minimum of 7 mo after treatment. Survival analysis (multivariable proportional hazards regression) was used to measure the effect of treatment on time to pregnancy. There was no benefit of treatment of endometritis before 4 wk postpartum. Administration of PGF2 alpha between 20 and 26 DIM to cows with endometritis that did not have a palpable corpus luteum was associated with a significant reduction in pregnancy rate. Between 27 and 33 DIM, cows with endometritis treated with cephapirin i.u. had a significantly shorter time to pregnancy than untreated cows (hazard ratio = 1.63). In this time period, there was no difference in pregnancy rate between PGF2 alpha and untreated cows, but the difference in pregnancy rate between cows treated with cephapirin i.u. and with PGF2 alpha was not statistically significant. Treatment of postpartum endometritis should be reserved for cases diagnosed after 26 DIM, based on criteria that are associated with subsequent pregnancy rate.LR: 20061115; PUBM: Print; JID: 2985126R; 0 (Anti-Bacterial Agents); 21593-23-7 (Cephapirin); 40665-92-7 (Cloprostenol); ppublishSource type: Electronic(1
Graphical dataset on important medicinal plants used for curing dental issues in Manoor Valley, Mansehra, Pakistan
No full textAbstractThe graphical dataset in this paper is related to the research article entitled “A novel survey of the ethno medicinal knowledge of dental problems in Manoor Valley (Northern Himalaya), Pakistan” (I.U. Rahman, F. Ijaz, Z. Iqbal, A. Afzal, N. Ali, M. Afzal, M.A. Khan, S. Muhammad, G. Qadir, M. Asif, 2016) [1]. This article describes how the local community of Manoor Valley practices cultural / traditional knowledge for dental problems. For the recorded data of 25 medicinal plants, six quantitative ethnomedicinal statistical approaches / equations were used. Out of these indices, four were used to measure the most imported and cited medicinal plant species while two for the comparative analysis to evaluate the novelty of work
Satisfied Workers, Retained Workers: Effects of Work and Work Environment on Homecare Workers' Job Satisfaction, Stress, Physical Health, and Retention
No full textThe goal of this project was to assist health system managers and policy makers develop policies and strategies to recruit and retain human resources in the homecare sector and have a satisfied, healthy workforce. The overall research question was: How do the work characteristics of homecare workers and the work environment in homecare contribute to job satisfaction, stress, physical health, and retention? The research is designed as a mixed-method approach with both qualitative and quantitative data. Results showed that restructuring and organizational change in the homecare sector has contributed to both mental and physical health problems (including job stress and musculoskeletal disorders), job dissatisfaction, and retention problems. Factors that contribute to higher levels of satisfaction and the propensity to stay with the organization include organizational and peer support, working one-on-one with clients, doing emotional labour (that is, the work involved in dealing with other people’s feelings), and satisfaction with schedules, pay, and benefits. This study also examined the association between job flexibility and job insecurity and self-reported musculoskeletal disorders and found no relationship between these variables and musculoskeletal disorders.home care workers, retention, job satisfaction
Home and Mortgage Ownership of the Dutch Elderly: Explaining Cohort, Time and Age Effects
No full textThe relationship between home ownership of Dutch elderly households and age is strongly negative. Other studies suggest that this age gradient should be attributed to a cohort effect. In this paper we investigate where those cohort effects come from. We also observe that mortgage ownership among elderly home-owners increased considerably during the nineties. Using panel data we estimate models explaining home and mortgage ownership by age, cohort, and time effects, as well as other factors. Cohort and time effects are modelled explicitly using macro economic and housing market related variables. We find that the level of GDP per capita when the household head was young is the main factor explaining generation effects in home ownership among the elderly. After accounting for cohort effects it also appears that home ownership decreases slightly with age. Mortgage ownership among elderly home owners rose considerably during the nineties due to house price increases and due to financial innovation in the mortgage market. Cohort effects are also important. A supplementary analysis suggests that those cohort effects are due to the fact that the accidental bequest motive is becoming less important.home ownership, mortgages, cohort effects
Underfunding of Defined Benefit Pension Plans and Benefit Guarantee Insurance - An Overview of Theory and Empirics
No full textWe review the theoretical literature on defined benefit (DB) pension plans, particularly focusing on the issue of plan underfunding and benefit guarantee insurance schemes. The literature shows that underfunding can, under reasonable assumptions, be an equilibrium outcome even in the absence of benefit insurance. The introduction of benefit guarantee funds was a reaction to the problem of underfunding, and we summarize the ensuing standard problems of moral hazard and adverse selection. We briefly discuss the small empirical research on the subject and propose directions for future research.defined benefit pension plans, underfunding, pension benefit guarantee
Survey Results of the New Health Care Worker Study: Implications of Changing Employment Patterns
No full textThis report examines the effects of contemporary employment arrangements on the quality of nursing work life, and the implications of these employment arrangements for individual nurses, the hospitals, and also for the organization. First we look at nurse work status (full-time, part-time or casual job), contract status (permanent or temporary), and employment preference as factors affecting commitment to the hospital and profession, job satisfaction, retention in the organization, and absenteeism from work. Second, we examine stress, burnout, and physical occupational health problems (in particular, musculoskeletal disorders), as affecting nurse and hospital outcomes. This project investigated how the quality of nursing worklife and career choices differ for nurses in full-time, part-time and casual employment, and whether nurses who have the employment arrangements they prefer enjoy a standard of worklife that encourages retention. We collected data for the study from 1,396 nurses employed at three large teaching hospitals in Southern Ontario (Hamilton Health Sciences, Kingston General Hospital, and St. Michael's Hospital in Toronto) using the New Health Care Worker Questionnaire. Results indicate that although a substantial majority of the nurses were employed in the type of job that they preferred, problems of stress, burnout and physical health problems were reported. Further, these problems affected the nurses' job satisfaction, commitment, and propensity to leave the hospitals.health care workers, employment status, nurses, job satisfaction, commitment, stress, burnout, physical health problems, MSD, propensity to leave

An Evaluation of the Working Income Tax Benefit
No full textThe federal government has implemented an earned income tax credit what it has called the Working Income Tax Benefit in the 2007 Budget. Edmund Phelps has argued that the earned income tax credit in the United States should be replaced with an employment subsidy. This paper assesses the importance of Phelps' concern, and related issues, for Canada. This debate is important for two reasons: the plight of those blocked by the "welfare wall" is dire, and the entire community has an interest in lower structural unemployment in an environment that involves an aging population and an accompanying labour shortage.earned income tax credit, employment subsidy, open economy
Is Foreign-Owned Capital a Bad Thing to Tax?
No full textThe aging population has raised at least two concerns about tax policy. First, taxes will need to be increased to cover higher public-pension and medical-care expenses when baby boomers have retired. Second, taxes can be cut in the meantime, as the government realizes the "fiscal dividend" that accompanies its debt reduction program (that has been motivated by the aging population development). This paper uses a simple endogenous growth analysis to examine these issues. It is assumed that sales tax increases are infeasible on political grounds. Two conclusions emerge: the income tax rate levied on domestic residents should be cut during the debt-reduction period, and the tax rate on foreigners whose capital is operating in Canada should be increased later on when the bulk of the baby boomers have retired.fiscal policy, endogenous growth, open economy
