Women, Ethics, and MBAs

We argue that the declining female enrollment in graduate business schools is a manifestation of gender bias in business education. The extant conceptual foundation of business education is one which views business activity in terms of a game with fixed and wholly material objectives. This concept betrays an underlying value system that reflects a male orientation. Business education is not merely amoral, therefore, but is gender biased. We suggest that business educators adopt a broadened behavioral rubric. Virtue-ethics theory provides such a rubric.     

Efficient inequality: differential allocation in the local public sector

This paper examines the consequences for social efficiency if the locally provided public input can be differentially allocated among residents. We derive the distributional efficiency condition, which is the distribution of public inputs that maximizes within-city gains from trade. Differential allocation also causes modifications to the standard (Samuelsonian) allocative efficiency condition. Additionally, we explore the consequences of differential allocation for the median voter model. Standard empirical voter models are seriously flawed because they fail to distinguish final public output production from either individual demand or the distribution of publicly provided inputs. Finally, we derive the club sharing efficiency condition.

Patterns of China's industrialization: Concentration,specialization, and clustering

This paper presents a few stylized facts on the patterns of China's industrialization by computing a set of multi-dimensional measures on industrial concentration, regional specialization, and clustering based on census data at the firm level in 1995 and 2004. Our results show that China's rapid industrialization is characterized by the following patterns: industries have become more spatially concentrated; regions have become increasingly specialized; and firms have become more interconnected, both within industries and within regions. In addition, the number of firms is growing faster in clustered areas than non-clustered ones. Together these patterns suggest that China's industrialization process is largely cluster-based—a phenomenon in which a large number of highly interconnected firms are located within a well-defined geographic region.     

Framing considerations in the prc: creating value in the contemporary chinese art market1

This study of art galleries in the Peoples’ Republic of China (PRC) uses a political economy approach to examine the contours of the art world and the art market. A Chinese art market based on the Western and Japanese models was created in the early twentieth century, but was abolished in 1949 when the PRC, under Chairman Mao, adopted a socialist framing model on a national scale. Breaking out of this totalizing frame was difficult despite the adoption of market socialism in 1979. The decade between 1979 and 1989 witnessed rapid surges of creativity, which were brought to a full stop by the 1989 Tiananmen Square massacre. In 1992, however, the national policy of rapid growth gave the cultural industry a sharp nudge. Since the mid‐1990s, two trends in the art world have emerged: a collaborative framework for developing contemporary PRC art (including commercial art) for both the internal and external markets; domestic art as a commentary on changing social and cultural values.     

Opportunities for Innovation in the Delivery of Interactive Retail Services

In today's volatile economy, innovation in providing interactive services to consumers through a variety of channels is critical in retailing. Interactive service innovations offer opportunities for retailers by creating new markets or offering new benefits in existing markets. They also pose threats as existing customers encounter new alternatives offered by competitors. This article explores some of the most promising opportunities in interactive retail services; namely, the increasing power of consumers, channel synergies, pre- and post-transaction service, optimal use of resources, and consumer heterogeneity. In discussing these areas of opportunity we identify knowledge gaps and suggest research questions relevant to these gaps that warrant attention. Collectively, these questions offer a research agenda for the topic of interactive retail service innovation.     

A Hierarchy-of-Effects Approach to Designing a Social Marketing Game

While there is great enthusiasm and interest by social marketers for games as a social marketing intervention, there is little evidence of the impact of these games. This research seeks to fill this gap by testing a theoretical model based on the experiential hierarchy of effects. An online game about the physiological effects of drinking was designed for high-school students and implemented in an educational curriculum with 223 participants (96% response rate) completing an online survey. The data was analyzed using structural equation modeling (SEM) and showed support for nine of the eleven hypotheses. The results show game characteristics of enjoyment (feel), knowledge (learn), and challenge (do) significantly related to attitudes and moderate-drinking behavioral intentions, ability to control drinking, and awareness of the physical consequences of drinking. There were no gender differences.     

Climate adaptation imperatives: untapped global maize yield opportunities

Climate change represents an unavoidable and growing challenge to food security, imposing new adaptation imperatives on all farmers. Maize is arguably the world's most productive grain crop, as measured by grain yield. However, maize yields vary dramatically due to many factors, including soils, climate, pests, disease, agronomic practices, and seed quality. The difference between observed yields and those achievable by optimized crop production methods is called the yield gap. In this work we quantified the current yield gap for 44 countries through the use of a large private-sector data set recently made available to the crop modelling community. The yield gap was quantified for three groups of countries, categorized by level of intensification. Observed yield gaps for high, medium, and low levels of intensification are 23%, 46%, and 68%, respectively. If all maize production countries were able to shrink their yield gap to 16.5% (as in the USA) an additional 335?million metric tons (MMT) of maize grain would be produced. This represents a 45% increase over the 741?MMT produced by these countries in 2010. These data demonstrate that a major untapped maize yield opportunity exists, especially in those countries where intensification has not kept pace with the rest of the world.     

Clinical burden and healthcare resource utilization among patients with chronic hypoparathyroidism,overall and by adequately vs not adequately controlled disease: a multi-country chart review

Abstract

Aims: To assess the real-world clinical burden and healthcare resource utilization (HRU) among patients with chronic hypoparathyroidism, overall and by adequately controlled (AC) vs not adequately controlled (NAC) disease, informed by guideline-recommended clinical management targets, including biochemistry and symptoms.

Materials and methods: In this retrospective online chart review, endocrinologists in the US, Canada, the UK, France, Germany, Italy, and Spain were randomly selected to review the medical charts of adult patients with chronic hypoparathyroidism receiving calcium and activated vitamin D. Patients’ demographics, disease characteristics, symptoms, comorbidities, and hypoparathyroidism-related HRU during the 1 year before the review date were assessed. Clinical burden and HRU were compared between patients with NAC and AC hypoparathyroidism.

Results: Of 614 patients with hypoparathyroidism (AC, N?=?442; NAC, N?=?172), the mean age was 43.6?years, and the majority were female (61.6%), Caucasian (78.8%), and had post-surgical hypoparathyroidism (74.4%). Mean duration of hypoparathyroidism was 46.0?months. Hypoparathyroidism-related symptoms and comorbidities were reported in 59.4% and 46.7% of patients, respectively; 90.7% of patients had ≥1 hypoparathyroidism-related HRU event. More patients with NAC (57.6%) vs AC (42.5%) hypoparathyroidism experienced ≥1 comorbidity including calcium/phosphate imbalances, and brain, cardiovascular, metabolic, and renal disorders (all p?<?0.01). More patients with NAC vs AC hypoparathyroidism incurred ≥1 hypoparathyroidism-related hospitalization (27.9% vs 16.3%) and emergency room visits (47.7% vs 38.5%), and patients with NAC vs AC hypoparathyroidism had a higher number of outpatient visits (3.6 vs 2.6; all p?<?0.05), in the 1-year observation period.

Limitations and conclusions: Limitations of this online chart review include possible under-estimation of disease burden, limited sample size, and the inability to rule out selection bias. Findings indicate that patients with chronic hypoparathyroidism experience substantial symptomatic and comorbid burdens resulting in frequent HRU, suggesting an unmet need, particularly in NAC disease.
