Measuring Production and Irrigation Efficiencies of Rice Farms: Evidence from the Punjab Province,Pakistan

We employ a non‐parametric approach, data envelopment analysis, to estimate the technical and irrigation efficiency of rice farms in the Punjab Province of Pakistan. We use a cross‐sectional dataset of 80 rice growers, including 45 tube‐well owners and 35 water buyers. Mean technical efficiency scores show that tube‐well owners and water buyers are operating at fairly high efficiency levels, indicating that access to technology is not a major constraint. However, irrigation inefficiency is pronounced, with water buyers being more inefficient than tube‐well owners. A bootstrap truncated regression is used to investigate the determinants of technical and irrigation efficiency. We suggest that groundwater management policies should be designed to address efficiency enhancing factors such as knowledge of crop water consumption requirement, better credit opportunities, outreach extension services and training programs.     

A theoretical framework of electronic word-of-mouth against the backdrop of social networking websites

This study proposed and tested a theoretical framework that explains electronic word-of-mouth (eWOM) against the backdrop of social networking websites (SNWs), which have gained substantial popularity among travelers. In particular, a United States (US) nationwide online survey was conducted and nine hypotheses were tested. The findings suggest that willingness to share knowledge and switching costs are positively related to eWOM communication. In addition, customer value (utilitarian) has positive relationships with willingness to share knowledge, perceived security, and switching cost, while customer value (hedonic) has positive relationships with willingness to share knowledge and switching costs. Last but not least, the findings indicate that perceived security does negatively impact eWOM. In light of the major findings, the article sets forth strategic implications for travel-related social networking websites.     

The effects of information order and hypothesis-testing strategies on auditors' judgments

This research examined the effects of information order and hypothesis-testing strategies on audit judgements. Auditors started with high or low prior beliefs about an internal control system and then reviewed both positive and negative evidence. The results suggest that, unless specifically requested to do so, auditors do not generally seek confirming evidence. We also found that prior beliefs have an effect on the importance of information order: with high prior beliefs, subjects' judgements were unaffected by information order, while low prior beliefs were associated with a recency effect.     

Pressure group power in the European Community

The renewed attention to the strengthening of the internal market of the European Community heralded by the Single European Act of 1986 is likely to produce a quantum leap in pressure group activity in Brussels, as business interests line up to exert their influence on the many harmonisation measures that are in the pipeline. How great an influence have European pressure groups exerted up till now? In what spheres has this influence been felt most strongly?     

Product standardisation in the food service industry: post-purchase attitudes and repurchase intentions of non-Muslims after consuming halal food

In order to satisfy the Muslim market segment, many restaurant and fast food companies in Western countries have standardised their products by switching to halal. The purpose of this research is to discover the extent to which non-Muslim consumers in non-Muslim countries experience cognitive dissonance when they think about restaurants and fast food outlets having likely served them halal-produced food, and the extent to which these consumers intend to repurchase halal food. Data came from a total sample of 1097 non-Muslim consumers in Canada, Spain and the United Kingdom. The full model, with religious identity, ethnic identification and interest in animal welfare as antecedents of cognitive dissonance, explained 35% of the variance in consumers’ repurchase intentions. Our findings suggest that many non-Muslims do not have a particular issue with consuming halal food, but they may react negatively if they unintentionally consume halal food and perceive that they have been deprived of information, or worse still, deliberately deceived. The research makes a number of contributions to marketing knowledge with regard to the negative spillover effects that can result from faith-based product standardisation, and the influences of consumer interest in animal welfare and deprivation of product information on consumer behaviour.     

Corroborating social media echelon in cancer research

Worldwide medical facilities differ, and for this reason, the causes of death can vary. Cancer is considered the second leading cause of death after heart disease worldwide, and the same causes of death are observed in the United States (US). Therefore, the purposes of this study are to explore worldwide research levels in the field of cancer and the social collaboration of researchers and institutions in this field. This article examines the structural patterns of international co-authors and co-institutions in science citation index papers in cancer research. The study uses measures from the social network analysis method, including degree centrality, betweenness centrality, eigenvector centrality, and effectiveness, to investigate the effects of social networks in the area of cancer research. Empirical analysis results identify the US is the most central country, followed by Germany, Italy, France, and China, in terms of co-authored networks in this research field. Institutional analysis results indicate that the University of Milan is at the top in terms of degree centrality. The Gustave Roussy Cancer Campus in France and German University of Düsseldorf occupy the second and fourth positions, respectively. The University of California in Los Angeles and Harvard University, both in the US, are at third and fifth positions, respectively.     

Overall survival,costs, and healthcare resource use by line of therapy in Medicare patients with newly diagnosed metastatic urothelial carcinoma

Aims: Medicare patients with metastatic or surgically unresectable urothelial carcinoma (mUC) often receive platinum-based chemotherapy as first line of therapy (LOT), but invariably progress, requiring additional LOTs and healthcare resource use (HCRU). To better understand the evolving mUC treatment landscape, the economic burden of chemotherapy-based mUC treatments among US Medicare patients was estimated.

Methods: Newly diagnosed Medicare patients with mUC were identified from the Surveillance, Epidemiology, and End Results (SEER)-Medicare database. Patients were followed from diagnosis to death, disenrollment, or end of study to characterize LOTs (first [LOT1], second [LOT2], and third or greater [LOT3+]). Kaplan-Meier methods were used to estimate overall survival (OS) by LOT. HCRU and mean costs were reported over the follow-up period, LOT duration, and maximum LOT received.

Results: Among 1,873 eligible patients with mUC (median age?=?77?years; median follow-up?=?7.5?months), 1,035 (55%) received no chemotherapy. Among chemotherapy-treated patients, 61% had LOT1 only, 25% had LOT1 and LOT2 only, and 14% had LOT3+. Median OS was 8.1?months, range was 4.3 (untreated) to 29.8 (LOT3+) months. HCRU frequency increased with additional LOTs. Mean cumulative per-patient cost was $82,912 for all patients, increasing with additional LOTs (untreated?=?$57,207; LOT1?=?$99,213; LOT2?=?$125,190; LOT3+?=?$163,884). Mean per patient per month cost was $18,827 for all patients, decreasing with increasing number of LOTs received (untreated?=?$27,211; LOT1?=?$9,601; LOT2?=?$7,325; LOT3+?=?$6,017).

Limitations: Potential for treatment misclassification when using the algorithm defining LOTs and non-generalizability of results to younger patients.

Conclusions: Over 50% of Medicare patients with mUC received no chemotherapy. Among chemotherapy-treated patients, most received only one LOT. Additional LOTs led to higher mean costs and HCRU, but as patients were followed longer, monthly costs decreased. As treatments evolve to include immuno-oncology agents, these findings provide a clinically relevant economic benchmark for mUC treatment across different traditional LOTs.     

Transatlantic Trade and Investment Partnership and Trans‐Pacific Partnership: Policy Options of China

As a result of deadlocked multilateral trade negotiations, many countries have embarked on the establishment of bilateral and regional trade agreements. Using the Global Trade Analysis Project database and a computable general equilibrium model, our paper focuses on the impacts of the Transatlantic Trade and Investment Partnership (TTIP) and the Trans‐Pacific Partnership (TPP) on the Chinese economy under three scenarios. The results suggest that when only the TTIP is realized, Chinese economic variables are negatively affected. When both the TTIP and the TPP are realized and China is excluded, the combined damage to the Chinese economy is higher than the damage with the TTIP alone. However, the inclusion of China in the TPP has a positively effect on economic variables in China. This indicates that the impacts of China's participation in the TPP compensate for the negative impacts of the TTIP. Therefore, China should consider being part of the TPP to offset the negative impacts of the TTIP.
