The trade-off between agriculture and biodiversity in marginal areas: Can crofting and bumblebee conservation be reconciled?

Crofting is a low intensity agricultural system restricted to the Highlands and Islands of northern Scotland typified by small scale mixed livestock production and rotational cropping activities. As with other low intensity farming systems across Europe, crofting is changing in response to a range of socio-economic factors. This is having a negative impact on the populations of rare bumblebees that are associated with this agricultural system. In this paper we use an ecological-economic modelling approach to examine the likely impacts of introducing two different management options for conserving bumblebees on croft land-use and income. Two linear programming models were constructed to represent the predominant crofting systems found in the Outer Hebrides, and varying constraints on bumblebee abundance were imposed to examine the trade-off between conservation and agricultural incomes. The model outputs illustrate that in some instances it is likely that both agricultural profits and bumblebee densities can be enhanced. We conclude that policy-makers should take into consideration the type of farming system when designing cost-effective agri-environment policies for low intensity farming systems, and that improvements in bee conservation are not necessarily in conflict with maintaining farm income.     

Reconceptualizing entrepreneurial framework conditions

This report is an empirical examination of entrepreneurial framework conditions—the environmental conditions that encourage and support entrepreneurial activity at the national level. In particular, it attempts to validate the framework conditions employed in the Global Entrepreneurship Monitor (GEM), a multi-year, multinational study of entrepreneurial activity widely used in entrepreneurship research. The validity of the GEM entrepreneurial framework conditions is examined using empirical analysis of data drawn from Global Competitiveness Report measures for 53 countries over 4 years. The data suggest an alternative conceptualization of entrepreneurial framework conditions: commercial munificence, technology openness, regulatory openness, and technology influx. These findings have implications for theorists and policy makers interested in antecedents to entrepreneurially based economic growth.

Measuring and Explaining Technical Efficiency in UK Potato Production

Technical efficiency in UK maincrop potato production is measured through the estimation of a stochastic frontier production function using cross section data for the 1992 crop year. Variations in the technical efficiency index across production units are explained through a number of managerial and farm characteristic variables following Battese and Coelli (1995). The technical efficiency index across production units ranges from 33 to 97 per cent. Irrigation of the potato crop and storage of potatoes after harvest are positively correlated with technical efficiency. Number of years of experience of growing potatoes, small scale farming practice and chitting of seed potatoes are all negatively correlated with technical efficiency.     

The twenty‐first‐century HR organization

Like any value‐creating staff function, HR departments should operate as a business within a business. Others have focused on the strategy and direction of HR departments. This article examines the next evolution for how HR department organization structure can deliver value based on two premises: (1) HR organization should be structurally aligned with the organization structure of the business and (2) because diversified/allied business models prevail, it is important to lay out the five roles and responsibilities of HR that respond to this organization model: service centers, corporate, centers of expertise, embedded HR, and operational HR. The article lays out the duties of each role, the relationship among these roles, and suggestions for implementing this new HR structure. © 2008 Wiley Periodicals, Inc.     

Store format choice and relationship quality in apparel retail: A study of young and early-middle aged shoppers in New Delhi region

Shopping format choice has been an interesting and important area of research in the academic literature from long time. However, research in this area is presently at a nascent stage in India. There are a very few studies which focus on store format choice in India which includes the works of Anand and Sinha (2009), Prasad and Aryasri (2008), Sinha and Banerjee (2004) and Tripathi and Sinha (2008). The present study compares three different retail formats (Discount stores, Exclusive stores and Multi-brand outlets) based on the shopper's perception of relationship quality (RQ) of these stores using multivariate techniques. For addressing, the objective of this study a sample of 313 shoppers is used. Results suggest that “conflict due to store” and “combined overall RQ due to the store and its employees” influence the store format choice. The RQ levels among the apparel store format are highly competitive.     

Segmenting Police ‘Customers’ on the Basis of their Service Quality Expectations

Customer expectations form the standards against which organisation performance is often assessed. Additionally, knowledge relating to customer expectations provides information concerning the differentiated performance requirements of heterogeneous customer groups. Relatively few studies have explored the segmentation potential of ‘customer expectations, und to the best of this author. knowledge, none of these has addressed the issue it1 the non-profit sector. This study addresses this need by investigating the extent to which demographics constitute expectation segmentation criteria in the context of the police service. Both the desired and predictive expectation standards are considered. Managerial arid research implications are given.     

TIME VARIABILITY IN MARKET RISK AVERSION

We adopt realized covariances to estimate the coefficient of risk aversion across portfolios and through time. Our approach yields second moments that are free from measurement error and not influenced by a specified model for expected returns. Supporting the permanent income hypothesis, we find risk aversion responds to consumption-smoothing behavior. As income increases, or as the consumption-to-income ratio falls, relative risk aversion decreases. We also document variation in risk aversion across portfolios: risk aversion is highest for small and value portfolios.     

Visualization of tsunami waves with Amira package

In recent years numerical investigations of tsunami wave propagation have been spurred by the magnitude 9.3 earthquake along the Andaman–Sumatra fault in December, 2004. Visualization of tsunami waves being modeled can yield a much better physical understanding about the manner of wave propagation over realistic seafloor bathymetries. In this paper we will review the basic physics of tsunami wave propagation and illustrate how these waves can be visualized with the Amira visualization package. We have employed both the linear and nonlinear versions of the shallow-water wave equation. We will give various examples illustrating how the files can be loaded by Amira, how the wave-heights of the tsunami waves can be portrayed and viewed with illumination from light sources and how movies can be used to facilitate physical understanding and give important information in the initial stages of wave generation from interaction with the ambient geological surroundings. We will show examples of tsunami waves being modeled in the South China Sea, Yellow Sea and southwest Pacific Ocean near the Solomon Islands. Visualization should be a part of any training program for teaching the public about the potential danger arising from tsunami waves. We propose that interactive visualization with a web-portal would be useful for understanding more complex tsunami wave behavior from solving the 3-D Navier–Stokes equation in the near field.     

Convenience and choice for consumers: the domestic acceptability of canned food between the 1870s and 1930s

Canned food once represented an astonishingly innovative technology although it is now largely ignored in food discourse. As with so much in our lives, familiarity renders an object invisible. To explore the changing social significance of canned food, as the format developed from scientific curiosity to domestic ubiquity, this paper examines reports in The Scotsman newspaper from the late 1870s to the 1930s. Although canned foods were slow to break into the mass market they were little short of revolutionary in the way they brought new tastes from across the world to ordinary British households. A few cans in the larder provided simple storage and reassurance that the unexpected visitor could be fed – perhaps with something a little out of the ordinary. Against this background of quiet assimilation into our food culture, canned food has been controversial and provided an unwitting rehearsal for contemporary food narratives. In these old newspapers, it was somewhat surprising to find reports of disquiet that are recognizable in our own times – the convenience of canned food posed a threat to culinary skills; questions were raised about the nutritional value and safety of processed food; we had become excessively reliant on imported food and disregarded our own produce.
