The economic burden of depression among adults with rheumatoid arthritis in the United States

Aims: Depression is the most frequent comorbidity reported among patients with rheumatoid arthritis (RA). Comorbid depression negatively impacts RA patients’ health-related quality-of-life, physical function, mental function, mortality, and experience of pain and symptom severity. The objective of this study was to assess healthcare utilization, expenditures, and work productivity among patients with RA with or without depression.

Materials and methods: Data from adult patients who had at least two visits each related to RA and depression over a 1-year period were extracted from the Truven Health MarketScan research databases. Outcomes comprised healthcare resource utilization, work productivity loss, and direct healthcare costs comparing patients with RA with depression (n?=?3,478) vs patients with RA without depression (n?=?43,222).

Results: Patients with RA and depression had a significantly greater relative risk of hospitalization and number of all-cause and RA-related hospitalizations, utilization of emergency services, days spent in the hospital, physician visits, and RA-related surgeries compared with RA patients without depression. Patients with RA and depression had a higher risk of and experienced more events and days of short-term disability compared with patients without depression. The incremental adjusted annual all-cause and RA-related direct costs were $8,488 (95% CI = $6,793–$10,223) and $578 (95% CI = –$98–$1,243), respectively, when comparing patients with RA and depression vs RA only.

Limitations: The current analysis is subject to the known limitations of retrospective studies based on administrative claims data.

Conclusions: This study suggested increased healthcare utilization, work productivity loss, and economic burden among RA patients due to comorbid depression. These findings emphasize the importance of managing depression and including depression as a factor when devising treatment algorithms for patients with RA.     

An investigation of the corporate identity construct in China: Managerial evidence from the high technology industry

The study develops and extends existing frameworks of corporate identity and investigates what organisations in China perceive as essential components of the corporate identity concept including their dimensions and contents. The study adopted a qualitative approach and the method of research was a case study. Using the soft-laddering approach, and a multidisciplinary categorisation of analyses of corporate literature and websites, a systematic analysis of the corporate identity was carried out. Different from previous studies, the study reveals new dimensions on the basis of the industry practitioners’ views. The context of China has shown to influence a different focus, more significantly around the ‘impression’ that corporate identity can contribute with commercially. It is suggested that new high-tech firms in China may not have enough experience and capacity to engage in a more holistic corporate identity concept provided. The lack of such experience is particularly likely for new firms, which are still in their early stage of development. Implications for management of corporate identity in China are presented along with directions for further research in the marketing communications literature.     

Grey Power: An Empirical Investigation of the Impact of Parallel Imports on Market Prices

The persistence of price discrimination across international markets with falling costs of unofficial importing is both paradox and policy concern. E-commerce facilitates a “grey” market in parallel imports, particularly for high-value goods such as electronics. This paper explores the impact of unofficial imports on price using a panel of product markets mediated via an Internet shopbot. It finds the presence of an import model lowers prices across the market. However, unlike the refurbished model it is not simply an inferior substitute. The import price discount increases over the model life cycle, suggesting that model-specific preferences fall as each model ages.

Global Entrepreneurship Monitor: Data Collection Design and Implementation 1998–2003

The Global Entrepreneurship Monitor research program was designed as a comprehensive assessment of the role of entrepreneurship in national economic growth. The conceptual model reflected in a wide range of factors associated with national variations in entrepreneurial activity and the major contextual features. Empirical tests of the many relationships in the model required four major data collection activities: adult population surveys, unstructured interviews with national experts, self-administered questionnaires completed by national experts, and assembly of relevant standardized measures from existing cross-national data sets. Adult population surveys were implemented to identify those entrepreneurially active, which required a set of precise criteria and careful processing to ensure harmonized counts and prevalence rates across 41 countries. Existing evidence on measures of reliability indicates that the measures met contemporary standards and the project was cost-effective.     

Moral management in competitive markets

The intrinsic motivation of a firm’s management for engaging in prosocial behavior is an important determinant of a firm’s social conduct. I provide the first model in which firms run by morally motivated managers engage in corporate social responsibility (CSR) in a competitive setting. Moral management crowds out a competitor’s strategic CSR, increasing profitability and leading shareholders to strategically delegate moral managers, although necessary for socially optimal CSR is that shareholders be morally motivated as well. Shareholders appoint managers that engage in a socially excessive amount of CSR, counter to existing literature, whenever product‐market competition is sufficiently intense.     

A tactical retreat? Conceptualising the dynamics of European grocery retail divestment from East Asia

The internationalisation of the firm is a highly dynamic process, in which periods of investment and expansion intermingle with periods of divestment and retrenchment. Academic research to date has focused on identifying the reasons for and the processes of divestment. Empirical studies either evidence generic pressures or provide case studies of specific incidents. There few longitudinal studies of international divestment, consequently the dynamic interactions between host market, home market and firm level factors, and how the institutional context changes over time is underplayed. This paper seeks to rectify this gap in our understanding.We explore the rationale and evolving dynamics of European grocery retail divestment in East Asia over a thirty year period. Taking an inductive approach and drawing on analysis of contemporary narratives drawn from company documentation, trade journals, newsfeeds and market reports, three phases can be identified characterised by specific factors and combinations of factors which intersect to provide the key pressures and stimuli for divestment. We conclude that at different time periods, different internal and external contextual influences manifest themselves through different priorities within the firm’s strategy – marked by a switch from local (host) market, to regional, to global firm-centric considerations. Longitudinal analyses allow a greater recognition of this dynamic interplay of factors, and the changes in these relationships, and provides a more nuanced understanding of the international divestment process.     

Reduced tillage and nitrogen effects on soil water dynamics and maize (Zea mays L.) yield under semi-arid conditions

Soil water and nutrients are critical drivers of crop production for smallholders of southern Africa. A three-year study was conducted to assess the effect of integrating single and double ploughing, ripping and planting basins with nitrogen fertilizer (0, 10 and 20?kg?N?ha^–1) on soil water dynamics and maize (Zea mays L.) yields. The experimental design was factorial with four tillage methods and three nitrogen levels as treatment factors. The study was conducted under semi-arid conditions of Zimbabwe. Tillage methods had similar soil water patterns in the profile and no tillage?×?N interaction effects were observed on soil water dynamics. Soil water penetrated deeper into the profile under ripper and basin methods than conventionally ploughed treatments. Nitrogen increased maize yields (14–96%) and rainwater-use efficiency (20–92%) regardless of tillage methods and growing season quality. However, more studies are required to explore complementary techniques that can improve rainwater capture and prolong soil water storage, and improve soil fertility.     

Employment Protection,Threat and Incentive Effects on Worker Absence

This article provides new evidence on the effect of changes in employment protection on worker absence. We use novel multi‐organization data to examine changes in worker absence as workers move from temporary to permanent employment contracts. We demonstrate a robust positive effect of employment protection on sickness absence. It has also been suggested that the impact of employment protection on absence and effort is due to a fear of dismissal. We also provide evidence that suggests that temporary workers' absence is influenced by incentives to attain jobs with protection that is unrelated to threat of dismissal. This has not been considered in earlier research. This channel of employment protection effects has important policy implications.     

Promoting Tourism,Projecting Power: The Role of Television Commercials

This paper analyzes television commercials (TVCs) launched by Korea Tourism Organization (KTO) from 1999 to 2012. By repeating shots of traditional and Korean popular (k-pop) culture, high-tech machinery, and sportsmanship, it is fair to say that Korean tourism TVCs both reflected and fueled the fad a target audience has for Korea. Hence the commercials not only promoted tourism, they were also projecting national power in general and cultural power in particular. It is surmised that through power projection the TVCs intend to create a country halo effect so that the country’s products and services may enjoy an aspired added value.
