This study sets out to test the assumption that concepts of leadership differ as a function of cultural differences in Europe and to identify dimensions which describe differences in leadership concepts across European countries. Middle‐level managers (N = 6052) from 22 European countries rated 112 questionnaire items containing descriptions of leadership traits and behaviours. For each attribute respondents rated how well it fits their concept of an outstanding business leader. The findings support the assumption that leadership concepts are culturally endorsed. Specifically, clusters of European countries which share similar cultural values according to prior cross‐cultural research (Ronen & Shenkar, 1985), also share similar leadership concepts. The leadership prototypicality dimensions found are highly correlated with cultural dimensions reported in a comprehensive cross‐cultural study of contemporary Europe (Smith, Dugan, & Trompenaars, 1996). The ordering of countries on the leadership dimensions is considered a useful tool with which to model differences between leadership concepts of different cultural origin in Europe. Practical implications for cross‐cultural management, both in European and non‐European settings, are discussed.

Purpose -This paper aims to identify key variables that influence the variability of labour turnover. Design/methodology/approach -The approach used in this research is a case study of a major retailer. The key data sources are an index for local competitive and labour market factors, an annual employee survey, and internal labour turnover data for each UK unit of the retailer. The method used for analysis is stepwise regression which identifies the key relationships that predict labour turnover. Findings -The findings show that environmental factors such as local labour markets have a major influence on labour turnover. Organisational factors such as company culture and values are a significant influence. Management behaviour as seen through operational and control variables are also of importance. Individual employee variables are also important in decisions concerning turnover.Research limitations/implications -The statistical analysis accounts for 38.7 per cent of the total variance in labour turnover. There are, therefore, other factors which are not assessed in this paper which also contribute to labour turnover. Whilst this study is of retail units across the UK as a whole, it is of one organisation and statistical generalisations cannot be made from this research. Practical implications -A significant paradox is found in which, as employees become more embedded and familiar with the organisation, its valency for them diminishes and labour turnover increases. This poses a challenge for retailers: how can they retain valued employees who find that as their self-esteem increases they wish to search for better jobs elsewhere? Originality/value -This research uses a statistical approach to provide new findings concerning the attitudes of individuals to their work and good explanations of the factors involved in labour turnover. It also provides statistical predictions which could be used by managers who wish to improve performance and decrease labour turnover at the retail unit level.

Bacteria are surrounded by a complex cell envelope made up of one or two membranes supplemented with a layer of peptidoglycan (PG). The envelope is responsible for the protection of bacteria against lysis in their oft‐unpredictable environments and it contributes to cell integrity, morphology, signaling, nutrient/small‐molecule transport, and, in the case of pathogenic bacteria, host–pathogen interactions and virulence. The cell envelope requires considerable remodeling during cell division in order to produce genetically identical progeny. Several proteinaceous machines are responsible for the homeostasis of the cell envelope and their activities must be kept coordinated in order to ensure the remodeling of the envelope is temporally and spatially regulated correctly during multiple cycles of cell division and growth. This review aims to highlight the complexity of the components of the cell envelope, but focusses specifically on the molecular apparatuses involved in the synthesis of the PG wall, and the degree of cross talk necessary between the cell division and the cell wall remodeling machineries to coordinate PG remodeling during division. The current understanding of many of the proteins discussed here has relied on structural studies, and this review concentrates particularly on this structural work.

Bacterial cell wall peptidoglycan is essential, and its synthesis is the target of clinically important antibiotics such as β-lactams. β-lactams target penicillin-binding proteins (PBPs) that assemble new peptidoglycan from its building blocks. The human pathogen Staphylococcus aureus only has two essential PBPs that can carry out all the functions necessary for growth and division.
