How much do we really lose?âYield losses in the proximity of natural landscape elements in agricultural landscapes
Natural landscape elements (NLEs) in agricultural landscapes contribute to biodiversity and ecosystem services, but are also regarded as an obstacle for largeâscale agricultural production. However, the effects of NLEs on crop yield have rarely been measured. Here, we investigated how different bordering structures, such as agricultural roads, fieldâtoâfield borders, forests, hedgerows, and kettle holes, influence agricultural yields. We hypothesized that (a) yield values at field borders differ from midâfield yields and that (b) the extent of this change in yields depends on the bordering structure.
We measured winter wheat yields along transects with logâscaled distances from the border into the agricultural field within two intensively managed agricultural landscapes in Germany (2014 near Göttingen, and 2015â2017 in the Uckermark).
We observed a yield loss adjacent to every investigated bordering structure of 11%â38% in comparison with midâfield yields. However, depending on the bordering structure, this yield loss disappeared at different distances. While the proximity of kettle holes did not affect yields more than neighboring agricultural fields, woody landscape elements had strong effects on winter wheat yields. Notably, 95% of midâfield yields could already be reached at a distance of 11.3 m from a kettle hole and at a distance of 17.8 m from hedgerows as well as forest borders.
Our findings suggest that yield losses are especially relevant directly adjacent to woody landscape elements, but not adjacent to inâfield water bodies. This highlights the potential to simultaneously counteract yield losses close to the field border and enhance biodiversity by combining different NLEs in agricultural landscapes such as creating strips of extensive grassland vegetation between woody landscape elements and agricultural fields. In conclusion, our results can be used to quantify ecocompensations to find optimal solutions for the delivery of productive and regulative ecosystem services in heterogeneous agricultural landscapes
The Biological Standard of Living in the two Germanies.
Physical stature is used as a proxy for the biological standard of living in the two Germanies before and after unification in an analysis of a cross-sectional sample (1998) of adult heights, as well as among military recruits of the 1990s. West Germans tended to be taller than East Germans throughout the period under consideration. Contrary to official proclamations of a classless society, there were substantial social differences in physical stature in East-Germany. Social differences in height were greater in the East among females, and less among males than in the West. The difficulties experienced by the East-German population after 1961 is evident in the increase in social inequality of physical stature thereafter, as well as in the increasing gap relative to the height of the West-German population. After unification, however, there is a tendency for East-German males, but not of females, to catch up with their West-German counterparts
The status of IT service management in health care - ITILÂź in selected European countries
<p>Abstract</p> <p>Background</p> <p>Due to the strained financial situation in the healthcare sector, hospitals and other healthcare providers are facing an increasing pressure to improve their efficiency and to reduce costs. These trends challenge health care organizations to introduce innovative information technology (IT) based supportive processes. To guarantee that IT supports the clinical processes perfectly, IT must be managed proactively. However, until now, there is only very few research on IT service management especially on ITIL<sup>Âź </sup>implementations in the health care context.</p> <p>Methods</p> <p>The current study aims at exploring knowledge about and acceptance of IT service management (especially ITIL<sup>Âź</sup>) in hospitals in Austria and its neighboring regions Bavaria (Germany), Slovakia, South Tyrol (Italy) and Switzerland. Therefore highly standardized interviews with the respective head of information technology (CIO, IT manager) were conducted for selected hospitals from the different regions. In total 75 hospitals were interviewed. Data gathered was analyzed using descriptive statistics and where necessary methods of qualitative content analysis.</p> <p>Results</p> <p>In most regions, two-thirds or more of the participating IT managers claim to be familiar with the concepts of IT service management and of ITIL<sup>Âź</sup>. IT managers expect from ITIL<sup>Âź </sup>mostly better IT services, followed by an increased productivity and a reduction of IT cost. But only five hospitals said to have implemented at least parts of ITIL<sup>Âź</sup>, and eight hospitals stated to be planning to do this in the next two years. When it comes to ITIL<sup>Âź</sup>, Switzerland and Bavaria seem to be ahead of the other countries. There, the highest levels of knowledge, the highest number of implementations or plans of an implementation as well as the highest number of ITIL<sup>Âź </sup>certified staff members were observed.</p> <p>Conclusion</p> <p>The results collected through this study indicate that the idea of IT services and IT service management is still not widely recognized in hospitals in the countries and regions of the study. It is also indicated that hospitals need further assistance in order to be able to successfully implement ITIL<sup>Âź</sup>. Overall, research on IT service management and ITIL<sup>Âź </sup>in health care is rare.</p
Factors associated with underutilization of antenatal care services in Indonesia: results of Indonesia Demographic and Health Survey 2002/2003 and 2007
<p>Abstract</p> <p>Background</p> <p>Antenatal care aims to prevent maternal and perinatal mortality and morbidity. In Indonesia, at least four antenatal visits are recommended during pregnancy. However, this service has been underutilized. This study aimed to examine factors associated with underutilization of antenatal care services in Indonesia.</p> <p>Methods</p> <p>We used data from Indonesia Demographic and Health Survey (IDHS) 2002/2003 and 2007. Information of 26,591 singleton live-born infants of the mothers' most recent birth within five years preceding each survey was examined. Twenty-three potential risk factors were identified and categorized into four main groups, external environment, predisposing, enabling, and need factors. Logistic regression models were used to examine the association between all potential risk factors and underutilization of antenatal services. The Population Attributable Risk (PAR) was calculated for selected significant factors associated with the outcome.</p> <p>Results</p> <p>Factors strongly associated with underutilization of antenatal care services were infants from rural areas and from outer Java-Bali region, infants from low household wealth index and with low maternal education level, and high birth rank infants with short birth interval of less than two years. Other associated factors identified included mothers reporting distance to health facilities as a major problem, mothers less exposed to mass media, and mothers reporting no obstetric complications during pregnancy. The PAR showed that 55% of the total risks for underutilization of antenatal care services were attributable to the combined low household wealth index and low maternal education level.</p> <p>Conclusions</p> <p>Strategies to increase the accessibility and availability of health care services are important particularly for communities in rural areas. Financial support that enables mothers from poor households to use health services will be beneficial. Health promotion programs targeting mothers with low education are vital to increase their awareness about the importance of antenatal services.</p
Does psychopathology at admission predict the length of inpatient stay in psychiatry? Implications for financing psychiatric services
Background: The debate on appropriate financing systems in inpatient psychiatry is ongoing. In this context, it is important to control resource use in terms of length of stay (LOS), which is the most costly factor in inpatient care and the one that can be influenced most easily. Previous studies have shown that psychiatric diagnoses provide only limited justification for explaining variation in LOS, and it has been suggested that measures such as psychopathology might be more appropriate to predict resource use. Therefore, we investigated the relationship between LOS and psychopathological syndromes or symptoms at admission as well as other characteristics such as sociodemographic and clinical variables.
Methods: We considered routine medical data of patients admitted to the Psychiatric University Hospital Zurich in the years 2008 and 2009. Complete data on psychopathology at hospital admission were available in 3,220 inpatient episodes. A subsample of 2,939 inpatient episodes was considered in final statistical models, including psychopathology as well as complete datasets of further measures (e.g. sociodemographic, clinical, treatment-related and psychosocial variables). We used multivariate linear as well as logistic regression analysis with forward selection procedure to determine the predictors of LOS.
Results: All but two syndrome scores (mania, hostility) were positively related to the length of stay. Final statistical models showed that syndromes or symptoms explained about 5% of the variation in length of stay. The inclusion of syndromes or symptoms as well as basic treatment variables and other factors led to an explained variation of up to 25%.
Conclusions: Psychopathological syndromes and symptoms at admission and further characteristics only explained a small proportion of the length of inpatient stay. Thus, according to our sample, psychopathology might not be suitable as a primary indicator for estimating LOS and contingent costs. This might be considered in the development of future costing systems in psychiatry
Competition and Gender Prejudice: Are Discriminatory Employers Doomed to Fail?
According to Becker's (1957) famous theory on discrimination, entrepreneurs with a strong prejudice against female workers forgo profits by submitting to their tastes. In a competitive market their firms lack efficiency and are therefore forced to leave. We present new empirical evidence for this prediction by studying the survival of startup firms in a large longitudinal matched employer-employee data set from Austria. Our results show that firms with strong preferences for discrimination, i.e. a low share of female employees relatively to the industry average, have significantly shorter survival rates. This is especially relevant for firms starting out with female shares in the lower tail of the distribution. They exit about 18 months earlier than firms with a median share of females. We see no differences in survival between firms at the top of the female share distribution and at the median, though. We further document that highly discriminatory firms that manage to survive submit to market powers and increase their female workforce over time
Mortality in Central Java: results from the indonesian mortality registration system strengthening project
Background. Mortality statistics from death registration systems are essential for health policy and development. Indonesia has recently mandated compulsory death registration across the entire country in December 2006. This article describes the methods and results from activities to ascertain causes of registered deaths in two pilot registration areas in Central Java during 2006-2007. The methods involved several steps, starting with adaptation of international standards for reporting causes of registered deaths for implementation in two sites, Surakarta (urban) and Pekalongan (rural). Causes for hospital deaths were certified by attending physicians. Verbal autopsies were used for home deaths. Underlying causes were coded using ICD-10. Completeness of registration was assessed in a sample of villages and urban wards by triangulating data from the health sector, the civil registration system, and an independent household survey. Finally, summary mortality indicators and cause of death rankings were developed for each site. Findings. A total of 10,038 deaths were registered in the two sites during 2006-2007; yielding annual crude death rates of 5.9 to 6.8 per 1000. Data completeness was higher in rural areas (72.5%) as compared to urban areas (52%). Adjusted life expectancies at birth were higher for both males and females in the urban population as compared to the rural population. Stroke, ischaemic heart disease and chronic respiratory disease are prominent causes in both populations. Other important causes are diabetes and cancer in urban areas; and tuberculosis and diarrhoeal diseases in rural areas. Conclusions. Non-communicable diseases cause a significant proportion of premature mortality in Central Java. Implementing cause of death reporting in conjunction with death registration appears feasible in Indonesia. Better collaboration between health and registration sectors is required to improve data quality. These are the first local mortality measures for health policy and monitoring in Indonesia. Strong demand for data from different stakeholders can stimulate further strengthening of mortality registration systems
