Solid waste management practices and review of recovery and recycling operations in Turkey.

This paper provides a general overview of solid waste data and management practices employed in Turkey during the last decade. Municipal solid waste statistics and management practices including waste recovery and recycling initiatives have been evaluated. Detailed data on solid waste management practices including collection, recovery and disposal, together with the results of cost analyses, have been presented. Based on these evaluations basic cost estimations on collection and sorting of recyclable solid waste in Turkey have been provided. The results indicate that the household solid waste generation in Turkey, per capita, is around 0.6 kg/year, whereas municipal solid waste generation is close to 1 kg/year. The major constituents of municipal solid waste are organic in nature and approximately 1/4 of municipal solid waste is recyclable. Separate collection programmes for recyclable household waste by more than 60 municipalities, continuing in excess of 3 years, demonstrate solid evidence for public acceptance and continuing support from the citizens. Opinion polls indicate that more than 80% of the population in the project regions is ready and willing to participate in separate collection programmes. The analysis of output data of the Material Recovery Facilities shows that, although paper, including cardboard, is the main constituent, the composition of recyclable waste varies strongly by the source or the type of collection point.

Impoverishment of practice: analysis of effects of economic discourses in home care case management practice.

Home care is a health sector under increasing pressure. Demand is often said to be outstripping capacity, with constant change and retrenchment distinguishing features of the current context. This paper takes a reading of the current conditions of home care using data gathered during a field study of home care case management practices conducted in 2004. As economic discourses become increasingly influential in determining responses to client situations, case managers (and their managers) find themselves with limited capacity to exercise control over their practices. A growing gap between professionally influenced discourses--those presumably intended to guide practice--and organizational priorities creates a dissonance for case managers as the political-ethical dimensions of their practices are displaced by budget "realities." For front-line workers, such displacement cannot be sustained in their face-to-face encounters with clients, leading to a growing sense of frustration and powerlessness among these highly skilled practitioners.

Agricultural management practices to sustain crop yields and improve soil and environmental qualities.

In the past several decades, agricultural management practices consisting of intensive tillage and high rate of fertilization to improve crop yields have resulted in the degradation of soil and environmental qualities by increasing erosion and nutrient leaching in the groundwater and releasing greenhouses gases, such as carbon dioxide (CO2) and nitrous oxide (N2O), that cause global warming in the atmosphere by oxidation of soil organic matter. Consequently, management practices that sustain crop yields and improve soil and environmental qualities are needed. This paper reviews the findings of the effects of tillage practices, cover crops, and nitrogen (N) fertilization rates on crop yields, soil organic carbon (C) and N concentrations, and nitrate (NO3)-N leaching from the soil. Studies indicate that conservation tillage, such as no-till or reduced till, can increase soil organic C and N concentrations at 0- to 20-cm depth by as much as 7-17% in 8 years compared with conventional tillage without significantly altering crop yields. Similarly, cover cropping and 80-180 kg N ha(-1) year(-1) fertilization can increase soil organic C and N concentrations by as much as 4-12% compared with no cover cropping or N fertilization by increasing plant biomass and amount of C and N inputs to the soil. Reduced till, cover cropping, and decreased rate of N fertilization can reduce soil N leaching compared with conventional till, no cover cropping, and full rate of N fertilization. Management practices consisting of combinations of conservation tillage, mixture of legume and nonlegume cover crops, and reduced rate of N fertilization have the potentials for sustaining crop yields, increasing soil C and N storage, and reducing soil N leaching, thereby helping to improve soil and water qualities. Economical and social analyses of such practices are needed to find whether they are cost effective and acceptable to the farmers.

Dietitians' views of overweight and obese people and reported management practices.

OBJECTIVES: To examine dietitians' views of overweight and obese people, to explore the role of level of severity on these perceptions (overweight vs. obesity), and to explore the relationship between dietitians' views and their reported weight management practices. DESIGN: An independent measures survey, questioning dietitians about either overweight or obese people. PARTICIPANTS: One-hundred and eighty-seven members of the British Dietetic Association. MEASUREMENTS: A questionnaire exploring beliefs about the causes, attitudes, perceptions of responsibility and reported weight management practices. RESULTS: Physical inactivity was identified as an important causative factor for both overweight and obesity. Mood, eating too much of the wrong foods, repeated dieting and interpersonal factors were also seen as relatively important for both groups. Attitudes were mixed, but were generally neutral to positive. The most negative attitudes were described in terms of perceived reduced self-esteem, sexual attractiveness and health. Dietitians rated obese people more negatively than overweight people. They viewed both overweight and obese people as being responsible for their excess weight. They also reported very similar management practices for overweight and obese people. Beliefs about the causes of overweight explained more of the variance in practice than dietitians' attitudes towards or perceived responsibility of overweight and obese people. However, these associations were not consistent and strong, and other factors not investigated here are likely to have a greater influence on weight management practices.

Assessment of management practices in a small agricultural watershed in Southeast China.

In this study, an event-based agricultural non-point source pollution model (AGNPS) was calibrated and validated in an agricultural watershed in Southeast China. The AGNPS predicted runoff, peak runoff rate, nitrogen and phosphorus well matched the observed value during calibration and validation. The validated model was then applied to simulate performance of the two existed management practices and three alternative scenarios using current management practices as background losses of non-point source (NPS) pollutants. Simulations showed that the existed management practices (contour cultivation and multi-pond system) were very effective in reduction of nutrient losses. Although alternative practices, such as improved nutrient management, conversions of current orchards to woods, and their combined practices, certainly reduced the NPS pollutants from the watershed, a detailed cost-benefit analysis is necessary to select practices that could be implemented for further reduction of agricultural NPS pollutants.

Effects of intensive forest management practices on insect infestation levels and loblolly pine growth.

Intensive forest management practices have been shown to increase tree growth and shorten rotation time. However, they may also lead to an increased need for insect pest management because of higher infestation levels and lower action thresholds. To investigate the relationship between intensive management practices and insect infestation, maximum growth potential studies of loblolly pine, Pinus taeda L., were conducted over 4 yr using a hierarchy of cultural treatments. The treatments were herbaceous weed control (H), H + irrigation (I), H + I + fertilizer (F), and H + I + F + pest control (P). These treatments were monitored for differences in growth and insect infestation levels related to the increasing management intensities. The Nantucket pine tip moth, Rhyacionia frustrana (Comstock), was consistently found infesting study trees. In the third field season, the H + I + F + P treatment had significantly more southern pine coneworm, Dioryctria amatella (Hulst), attacks than the H and H + I treatments. There were significant differences in volume index (D2H) among all treatments after each of the four growing seasons. This study indicated that tree fertilization can increase coneworm infestation and demonstrated that tip moth management can improve tree growth initially. Future measurements will determine if the growth gains from tip moth management are transitory or sustainable.

Development of a core curriculum in professional growth: practice management military model.

Military medicine has faced some big challenges in recent years. Military treatment facilities have not been exempt from these alterations, as the American public has sought to reinvent government practices with regard to medicine. Until recently, professional education consisted almost entirely of emphasis in the particular content of the chosen field. Obstetrics and gynecology was one of the first medical specialties to recognize the importance of practice management, professional growth and development, and to require exposure to it as part of the residency process. The Department of Obstetrics and Gynecology's instructional objectives dealing with professional growth and development originated as part of the military-unique curriculum for physicians implemented at Tripler Army Medical Center in Hawaii. Later, these objectives were used at Madigan Army Medical Center in Tacoma, Washington. Recent changes in the health care environment, coupled with an increasing awareness of professional liability and the newer specter of managed care, force physicians to learn the cost of each health encounter and to be more familiar with the business aspects of health care. As medicine in general is changing, the curricula have been revised and tailored to the needs of our physicians with the addition of ethics, managed care, utilization, and practice management.

A study of bovine mastitis, milking procedures and management practices on 25 Estonian dairy herds.

BACKGROUND: Mastitis prevalence, milking procedures and management practices were investigated in 25 big dairy herds supplying milk to an Estonian dairy company. The aim of the study was to provide information for the company to be used in their new udder health improvement program to be set up after the completion of this study. METHODS: Quarter milk samples were collected from 3,166 cows for bacterial analysis and SCC (somatic cell counting). During the farm visit the veterinarian filled in a questionnaire about milking procedures and management practices with the help of farm managers. If the milk SCC of a cow or of a quarter exceeded 200,000/ml, the cow was defined as having mastitis. RESULTS: The percentage of cows having inflammation in one or more quarters measured by SCC (200,000/ml) was 52.7%. Corynebacterium bovis, Staphylococcus aureus and coagulase negative staphylococci were the most common bacterial isolates. Women as farm owners, and participating in the milking, were associated with lower mastitis prevalence on the farm. Peat bedding was associated with higher mastitis prevalence. CONCLUSION: We demonstrated relatively high mastitis prevalence in this study. Contagious bacteria (eg. S. aureus, C. bovis, S. agalactiae and coagulase negative staphylococci) caused most of the infections. These infections are usually spread from cow to cow at milking if the milking hygiene is not good enough. The mastitis situation could be improved by improving milking procedures and hygiene.

The use of a resource-based relative value scale (RBRVS) to determine practice expense costs: a novel technique of practice management for the vascular surgeon.

Vascular surgeons have had to contend with rising costs while their reimbursements have undergone steady reductions. The use of newer accounting techniques can help vascular surgeons better manage their practices, plan for future expansion, and control costs. This article reviews traditional accounting methods, together with activity-based costing (ABC) principles that have been used in the past for practice expense analysis. The main focus is on a new technique-resource-based costing (RBC)-which uses the widely available Resource-Based Relative Value Scale (RBRVS) as its basis. The RBC technique promises easier implementation as well as more flexibility in determining true costs of performing various procedures, as opposed to more traditional accounting methods. It is hoped that RBC will assist vascular surgeons in coping with decreasing reimbursement.

Constructing management practice in the new public management: the case of mental health managers.

There has been a growth in managerialism of professionals in the Public Sector. This paper contributes to this debate by examining perceptions of senior managers in mental health services within Health Authorities, NHS Trusts and Local Authorities' Social Services departments in Wales. The paper explores how different professions responded differently to the growth of managerialism. The results suggest important differences and similarities between management in health and social services settings.
