Dermatomyositis

Dermatomyositis is an inflammatory disease with an unknown cause affecting primarily the skin and muscles with an increased risk of malignancy.     

Do jet fuel price movements help forecast airline fares and the demand for air travel?

The paper studies the predictive content of jet fuel prices for the U.S. aviation industry through in-sample and out-of-sample forecasting exercises. Our results suggest the possibility of limited improvements in the predictions of airline fares, and little evidence of predictability from jet fuel prices to measures of air travel demand.     

Percentage Rents with Agency

Retail leases often include a constant percentage rent above a breakpoint. Most breakpoints are restricted to a natural breakpoint, calculated as base rent divided by percentage rent. Frequently, breakpoints are much greater than sales when leases are signed. Both within and across categories of retail, percentage rents vary widely. On average percentage rents are lowest for large stores, like anchors, and highest for small stores with high operating margins. Retail leases with these and other common characteristics are shown to support second‐best investments by landlords in their stores both inside and outside shopping centers. The second‐best schedule of breakpoints and percentage rents is calculated explicitly.     

Effective dimensionality and factors affecting crop-livestock integration in West African savannas: a combination of principal component analysis and Tobit approaches

Crop‐livestock integration (CLI) to improve natural resource management for increased productivity is evolving in Nigeria and West Africa. Processes in the evolution and factors that influence it still need to be well understood. This article proposes and tests a new framework for measuring the multiple dimensionality of CLI. The framework derives a CLI index using the principal components of its most common single measures; it develops geographic information systems (GIS)‐based village‐level ecological and market factors; and it estimates parameters of factors affecting CLI using the derived index as the dependent variable in a Tobit model. The framework is tested using empirical data from 634 farm households in 11 geo‐referenced villages in the Sudan savanna (SS) and northern Guinea savanna (NGS), Nigeria. Along a north–south (SS to NGS) axis, CLI initially increases, peaking around 11.2°N, and then declines. This latitude probably identifies the boundary below which disease challenge constrains traditional livestock production and CLI. This polynomial pattern of CLI is contrary to an expected linear increase along lines of perceived potentials for rain‐fed crop production. Household resources, GIS‐derived village‐level market factors, and institutional factors also significantly affect CLI. Ecological and institutional factors have most impact on the probability of adoption and use intensities of CLI. The incorporation of GIS‐derived market factors with household and institutional variables in an econometric model offers new opportunities for assessing patterns of evolution of CLI, comparing results across sites, and targeting recommendation domains objectively. A comparison with results from more common methods of running independent models for individual indicators of CLI shows that this new framework is an effective way of reducing the multiple dimensionality of CLI to gain quicker, well‐focused knowledge of the processes of agricultural intensification.     

A Model Integrating the Multidimensional Developmental Theory of Privacy and Theory of Planned Behavior to Examine Fabrication of Information Online

We investigate the antecedents behind online consumers' attempt to disguise their identities through fabrication. We first develop a general conceptual model that draws on two extant theoretical frameworks: (1) Laufer and Wolfe's Multidimensional Approach to Privacy, and (2) Ajzen's Theory of Planned Behavior (TPB) with Perceived Moral Obligation. Next we conduct an empirical study using SEM to test the portion of the conceptual model based on the TPB framework. Results demonstrate that Attitudes, Perceived Behavioral Control, and Perceived Moral Obligation are significant drivers of fabrication, while Subjective Norms are not. Anonymity, one of the unique characteristics of the Internet compared to in-store environments, likely contributed to the intention to fabricate information. In the concluding section we discuss the implications of our empirical results, industry self-regulation and public policy considerations, and how future research can draw upon the conceptual Laufer and Wolfe framework, particularly the calculus of behavior construct, to further enrich our understanding of fabrication behavior on the Internet.     

Age-related differences in responses to affective vs. rational ads for hedonic vs. utilitarian products

This research investigated the moderating role of product category type (hedonic vs. utilitarian) on age-related differences in responses to affective vs. rational ads. An experiment showed that elderly consumers (age 65 plus) had more favorable attitudes toward affective (vs. rational) ads, regardless of product category type. In contrast, young adult consumers (age 18–25) favored affective ads only for hedonic products. They favored rational ads for utilitarian products. Results of the experiment imply that, to explain age-related differences in decision making, researchers must take into account age-related differences in motivational states apart from apparent shortfalls in cognition.     

Reinforcing Ethical Decision Making Through Corporate Culture

Behaving ethically depends on the ability to recognize that ethical issues exist, to see from an ethical point of view. This ability to see and respond ethically may be related more to attributes of corporate culture than to attributes of individual employees. Efforts to increase ethical standards and decrease pressure to behave unethically should therefore concentrate on the organization and its culture. The purpose of this paper is to discuss how total quality (TQ) techniques can facilitate the development of a cooperative corporate culture that promotes and encourages ethical behavior throughout an organization.     

Export stimulation of micro- and small locally owned firms from emerging environments: New evidence

This paper reports the findings from an empirical investigation into the export stimulation behaviour of micro- and small locally owned firms. It investigates whether the decision to initiate exporting in these smaller firms is a result of a systematic planned investigation into foreign market opportunities or is a mere response to fortuitous circumstances. This issue has received extensive attention in the literature on the internationalisation of firms from large developed environments, but very little is known about it in emerging environments especially small, open economies. This study will add to the literature by investigating export stimulation from a small, emerging Caribbean economy, Jamaica. Using a quantitative approach supported by insights from qualitative data gained during the fieldwork, the study analysed 20 stimuli that are demonstrated to impact export initiation decision. The key finding reveals that export initiation is a result of a planned systematic approach to international market rather than a mere response to fortuitous circumstances. The originality of this finding is in its extension of earlier work from developed economies to an emerging, resource-poor, open economy and its departure from analysing large and multinational firms to focus on micro- and small locally owned firms.

Widening the ‘representation gap'? The implications of the ‘lobbying act’ for worker representation in the UK

The Transparency of Lobbying, Non‐Party Campaigning and Trade Union Administration Act 2014 (the ‘Lobbying Act’) imposes tight restrictions on the campaigning and lobbying activities of civil society organisations in the UK, diminishing their capacity to represent the interests of working people and thus likely compounding the ‘representation gap’ within British workplaces. Along with austerity measures and employment law reforms, the legislation exemplifies the UK government's attempts to shift the balance of power further towards employers.
