Benzodiazepines and falling injuries in the elderly

Abstract

Objective: To investigate the use of benzodiazepines (BD) in relation to the risk of falling injuries in an elderly population (65 yrs. or older)

Design: An unmatched case-control study. Setting: The town of Pori, Finland

Participants: 380 subjects aged 65 years or over, who presented for medical treatment due to a fall during the 12 months from Sept. 1987 to Aug. 1988, and 342 controls, 65 years or older, selected from the population register. The control subjects were examined according to a schedule that corresponded in time (time of day, day of the week and month) to the time-distribution of falls in an earlier study

Outcome measure: All falls leading to medical treatment. BD use was determined from the serum, and the type of BD was determined by interviews and controlled from patient records

Results: We found a tendency toward a dose-response relationship between the serum BD concentration and the occurrence of falling injury. The risk of faling injury related to short-acting BDs was increased 5-fold and that for other BDs 2-fold compared to the risk among those without any BD in the serum. Conclusion: The results indicate that BD use is associated with falls in the elderly, and that short-acting BDs seem to be associated with falls more often. The results suggest caution in the use of BDs in the elderly.     

Two retailers go global – the geographical dimension

The world-wide expansion of two specialist retailers is analysed. Looming market saturation at home is a potential and quantifiable trigger (‘Why?’). It is paralleled by strong entrepreneurial ambition and possibly the desire to pre-empt competitors (‘When?’). Centralized and standardized operations favour organic growth through owned stores (‘How?’). The process follows roughly decreasing cultural closeness (‘Where?’), to which the logistics function coupled with relative market size may cause aberrations. In unfamiliar and distant markets, franchising is used which calls for a separate and more random entry sequence.     

Basking in reflected glory: Using customer reference relationships to build reputation in industrial markets

Corporate reputation is an important intangible asset that enables firms to establish customer relationships. Customer relationships, specifically customer reference relationships, can in turn be utilized to build supplier reputation in industrial markets. The aim of this conceptual article is to analyze the combination of these two concepts. It lays the foundation for further investigations into the effectiveness of reference customer relationships in enhancing supplier reputation. By developing propositions on the determinants impacting effectiveness of reputation transfer between customer and supplier firm, implications for practice and research in business marketing and corporate reputation management are derived.     

Market liquidity and depth on two different electronic trading systems: A comparison of Bund futures trading on the APT and DTB

This paper investigates the liquidity of two different electronic trading systems – the APT system at LIFFE and the DTB system. First we describe the different characteristics of the trading systems and give potential reasons as to why they might differ in liquidity. Second we investigate empirically the liquidity provided by the two trading system. The comparison is especially interesting because the Bund Futures instruments traded are identical and the markets are open simultaneously. The intra-day data used in the study is from August 1997 to February 1998. The results show that the APT has smaller spread but the DTB is slightly deeper.     

Communication as a determinant of organizational innovation

This study of 32 small and medium-sized industrial enterprises explored eight distinct aspects of communication, as appraised by the staff ( n  = 493), and innovative performance, assessed by two indicators: perceived innovation effectiveness and patent statistics obtained from the Patent Register at the National Board of Patents and Registration of Trademarks. The results showed that intra-organizational aspects of communication, such as encouragement of initiatives and critical evaluation of performance, were associated with both indicators of innovative performance. In addition, a participative climate and interaction between the personnel in R&D, marketing and production were related to perceived innovative effectiveness, whereas interaction with clients and other firms related to the number of patents in the organization. The link between communication and innovation was interdependent with the organizational and staff characteristics including the number of personnel, administrative and R&D intensity, the level of vocational training, and the age distribution of the staff.     

The geographical dimension of global retailing

The globalization of twenty well-known retailers and fast food operators is measured by two geographical indices, dispersion and locus, based on various measures of activity. Both are compared with similar indices based on the GDP. An attempt to explain varying degrees of globalization with own manufacturing, store ownership and company age fails. This leads to increasingly ‘soft’ verbal, even personalized, explanations.     

New challenges in professional cleaning: hygiene quality and monitoring of surfaces in private domestic homes

In many countries, changes in the pattern of working lives and ageing of the population increases the need for professional cleaning in private domestic homes. The objective of this study was to obtain basic knowledge concerning professional home cleaning. The study consisted of two parts. First, cleanability of surfaces contaminated with microbiological and organic soils was examined in the laboratory using cleaning cloths, detergents and rapid detection methods with potential for use in conjunction with professional cleaning in private homes. Second, hygienic conditions in three households were screened using the same rapid detection methods as in the laboratory experiments. According to the laboratory study, the cleaning efficiency of the non‐woven cloth was clearly poorer than that of the cleaning cloths containing microfibers. There were differences between the efficacy of the cleaning agents in removal of protein and microbiological soils. Despite the differences between surface topography observed with scanning electron microscopy, differences between the cleanability of the three examined surface materials (steel and two plastic surfaces) were small. In hygiene monitoring, the highest levels of total aerobic bacterial counts were detected in the plughole of the sink, on the eating table in kitchens and along the edge of the toilet washbowl and the cover of toilet seats. Low amounts of Enterobacteriaceae indicating faecal contamination were detected in the toilet and bathroom after cleaning. Moulds were not detected in any of the three households, and the amounts of yeasts were low. Detection methods, microbiological dipslides and the protein test, were well suited to the laboratory study. Furthermore, they complemented each other in the hygiene monitoring. The information obtained will be used for development of better practices in professional home cleaning. Good quality management in professional home cleaning and the cleanliness of surfaces in homes are important factors affecting comfort and safety.     

EMPIRICAL RESULTS CONCERNING VERTICAL AND HORIZONTAL REDISTRIBUTION IN FINLAND

Redistributional effects of income transfers, taxation and social goods in Finland have been studied making use of household surveys for 1966 and 1971 and the input-output study for 1970. According to the study the selection of income to be used as the criterion in carrying out the decile grouping substantially influences the picture that is obtained of the magnitude of redistribution. If factor income is used as the criterion in carrying out the decile grouping, the redistribution appears substantially greater than when disposable income is used as the criterion. On the other hand, whether income is calculated per capita or per household does not substantially influence the overall picture of redistribution obtained. The breakdown of factor income seems to have remained practically the same in Finland in the interval between the study years, while redistribution seems to have levelled income differences more in 1971 than in 1966.     

Strategies for Integrating Stakeholders into Sustainability Innovation: A Configurational Perspective

Sustainability is a key driver of innovation for products, services, and business models. Sustainability innovations are aimed at improving the environmental, social, and economic performance of the innovated solution. Given the complexity of many sustainability challenges, leading innovators may seek to boost their innovation capacity by tapping into the ideas, knowledge, and expertise of their stakeholders. In doing so they need to consider how many and which stakeholders to integrate into new product development (NPD) processes, and at what stage. This study investigates stakeholder integration strategies associated with high sustainability performance of innovation. Building on the literatures of sustainability innovation and stakeholder integration in the context of NPD, this study developed a configurational model to analyze stakeholder integration strategies. The empirical data consisted of 80 interviews and documents from 13 medium to large companies and their stakeholders in Europe. Using the fsQCA method, it was found that there is not just one effective strategy but three stakeholder integration strategies for high sustainability performance of innovation. The results imply that deep organizational engagement with stakeholders is necessary for the achievement of high performance. Otherwise, the three strategies range from progressive openness, which allows stakeholders to exert a fundamental influence on the sustainability innovation, to limited openness toward stakeholder integration. With the early secondary strategy pointing to progressive openness, companies integrate secondary stakeholders early on and so maximize the influence of different views on the innovation. As to limited openness, companies following the selective strategy limit the number of stakeholder groups in NPD but are indifferent to the timing of these groups’ inputs. Finally, the fine‐tuning strategy is least open to atypical views as it restricts the share of secondary stakeholders and only allows external inputs after the fuzzy front end phase when key decisions regarding the innovation have been made.
