Berufsbedingte Dermatosen bei Pflegenden

Ekzeme – eine h?ufig untersch?tzte Gefahr - Untersuchungen zeigen, dass die Lebensqualit?t durch berufsbedingte Hauterkrankungen genauso eingeschr?nkt wird wie durch einen Myokardinfarkt oder Schlaganfall. Das ist für Pflegende deshalb so bedeutsam, weil gerade in Pflegeberufen Kontakt zu potenziell Allergie ausl?senden Stoffen besteht.     

Strategic order splitting,order choice,and aggressiveness: Evidence from the Taiwan futures exchange

We investigate the strategic order‐splitting behavior and order aggressiveness of different types of traders using a unique dataset on the Taiwan Futures Exchange. By examining the trades and orders for each and every account, we find that, as compared with domestic institutional traders and individual traders, foreign institutional traders and futures proprietary firms are more likely to split their orders and it appears that the price adjustments after their trades are permanent. Foreign institutional traders and futures proprietary firms seem to be better informed, with their orders apparently being split so as to reveal their information on a gradual basis. Furthermore, we find that foreign institutional traders and futures proprietary firms use fewer market orders, choosing instead to submit aggressive limit orders, possibly due to their desire to make the most of their information advantage. © 2009 Wiley Periodicals, Inc.

An examination of consumers’ cross-shopping behaviour

This study addresses antecedents of cross-shopping behaviour. Five theory-driven hypotheses are derived and tested. The results indicate that impulse buying tendency and perceived time pressure have a statistically significant negative effect on supermarket patronage. Product assortment and price consciousness have a statistically significant negative effect on speciality store patronage, while impulse buying tendency and convenience orientation have a statistically significant positive effect on speciality store patronage. Perceived time pressure has a statistically significant positive effect on meat store patronage. This effect is, however, not statistically significant on seafood store patronage. The findings have managerial implications for both supermarkets and speciality stores.     

Consumer shopping orientations,non-store retailers,and consumers' patronage intentions: A multivariate investigation

Over the last few years, nonstore retailing has become an important and integral part of the American retailing scene. However, very little published research exists regarding these new methods of retailing. This study examines the role of consumers' shopping orientations, and type of nonstore method on consumers' patronage intentions of a set of selected products. The results are supportive of the two research hypotheses. Theoretical and managerial implications are discussed.     

Determinants of retirement planning behaviour and differences by age

This paper presents the results of an investigation into the determinants of retirement planning behaviour and differences among three age groups: 21‐ to 39‐year‐olds, 40‐ to 59‐year‐olds and those aged 60 years and older. A national survey of 911 individuals from households with incomes of $75 000 or greater was conducted in the US. The significance of socio‐demographic variables, the ability to recover from loss, behavioural tendencies and perceived or actual personal control were investigated; together with their role in the prediction of maximization of retirement contributions and ownership in the personal individual retirement account (IRA) or Keogh accounts. The results identified several significant variables in the prediction of ownership in a personal IRA or Keogh, including age, sources of financial information, being an early investor and investor activity. The results also identified several significant variables in the prediction of the maximization of retirement contributions, including employment, income, savings activity, ex ante research, review of investment performance, early investor, investor activity, such as planning for financial future, setting up automatic deposits and reviewing financial information in the mail.     

Technological complementarities, demand, and market power

Recent technological changes in many industries have generated numerous complementary technologies. A key implication of complementary technologies is that the demand for related services has tended to change both qualitatively and quantitatively. While the economics literature has examined various aspects, the effects of technological complementarity have not been fully flushed out. Using a simple model, this paper examines the implications of technological complementarity. How have firms’ pricing abilities changed with complementary technologies? What implications do complementary technologies have for regulation? Results show that technological complementarity has the potential to increase the market power of firms, possibly increasing prices to unprecedented levels. This holds whether demand elasticity is constant or variable. Policy implications are discussed.     

The future of the uplands

Upland areas provide UK society with many important functions, goods and services, but have experienced a number of disturbing trends and face an uncertain future. This paper outlines historic, current and future drivers of environmental, economic, socio-cultural and policy change in UK uplands, and assesses how these have affected or are likely to affect ways in which land is used and the provision of ecosystem services. Information is synthesised into scenarios summarising a range of possible futures anticipated for UK uplands to 2060 and beyond. Finally, innovations in science, technology, governance and policy are evaluated that could enable uplands to continue providing key ecosystem services under a range of scenarios. The paper concludes that many upland areas will need to be prepared for significant reductions in grazing and prescribed burning. Conversely, other areas could experience agricultural intensification, for example significant increases in grazing or an expansion of arable or bioenergy crops into upland valleys, due to anticipated increases in global demand for food and energy. These scenarios will take place in the context of climate change. Many may take place together and may interact with each other, with complex and unpredictable implications for the upland environment, economy and society. In this context, a number of advances are needed in science, technology and policy to maintain viable upland communities and the future provision of ecosystem services. These may include funding for ecological and hydrological restoration via carbon offsetting or other means. It may also involve advances in ecosystem service modelling, mapping and valuation, which through stakeholder participation could facilitate more integrated rural planning. New forms of environmental governance need to be explored that can empower those interested in developing upland economies to maintain thriving upland communities, while managing the ecosystem services they provide as efficiently as possible.     

The integration of microcomputers in marketing research and decision making

This paper focuses on the integrative and pervasive use of microcomputers in marketing research and managerial decision making. The marketing research process is conceptualized as consisting of six phases. At each phase, microcomputer applications and illustrative software are identified as implications for the practice of marketing research discussed. Next the paper illustrates the use of microcomputers in selected application areas such as market segmentation, sales forecasting, new product development, pricing and decision support and expert systems. Guidelines for the selection of microcomputer software in specific situations are provided. The paper concludes with some observations on the future applications of microcomputers in marketing research and decision making.     

Tree farms: Driving forces and regional patterns in the global expansion of forest plantations

People have planted trees in rural places with increasing frequency during the past two decades, but the circumstances in which they plant and the social forces inducing them to plant remain unclear. While forests that produce wood for industrial uses comprise an increasing number of the plantations, most of the growth has occurred in Asia where plantations that produce wood for local consumption remain important. Explanations for these trends take economic, political, and human ecological forms. Growth in urban and global markets for forest products, coupled with rural to urban migration, may spur the conversion of fields into tree farms. Government programs also stimulate tree planting. These programs occur frequently in nations with high population densities. Quantitative, cross-national analyses suggest that these forces combine in regionally distinctive ways to promote the expansion of forest plantations. In Africa and Asia plantations have expanded most rapidly in nations with densely populated rural districts, rural to urban migration, and government policies that promote tree planting. In the Americas and Oceania plantations have expanded rapidly in countries with relatively stable rural populations, low densities, and extensive tracts of land in pasture. If, as anticipated, the growing concern with global warming spurs further expansion in forest plantations in an effort to sequester carbon, questions about their social and ecological effects should become more pressing.
