Staffing and equipment decisions for services: An experimental analysis

Many service-oriented firms face demand/work load variations that occur both within and between days, and seasonally during the year. These service firms tend to develop staffing plans based on peak periods, resulting in substantial idle time during low demand periods. To counter this, some firms hire part-time employees to work peak periods to improve productivity. In this way, the cost per customer/transaction (unit) can be reduced.However, the staffing decision is more complex than just determining the number and timing of the work force. The development of good staffing plans must consider the impact of available work stations like telephone consoles and data entry terminals. To use effectively more personnel during peak periods, the firm must have sufficient work stations to assign this work force. Effective staff scheduling must consider simultaneously the work load variations, employ capabilities, and equipment requirements. This article presents a model that incorporates these factors into the decision-making process and examines their interaction.The model analysis illustrates how uncertainty in work load forecasts and staffing flexibility influence expected cost performance and equipment requirements. A set of computer simulation experiments are conducted using operating data from the proof and encoding departments for Ohio National Bank and Chemical Bank. The results suggest that increased staffing flexibility reduces the needed equipment investment, since part time staff can be scheduled more conveniently to meet varying work loads. Also, basing capital equipment decisions on peak work load levels can substantially increase total operating costs. With these costs explicitly estimated, managers can weigh them against desired service level goals to determine the appropriate balance.     

Retrenchment: Cause of turnaround or consequence of decline?

In a recent investigation of the turnaround attempts of 32 U.S. textile firms, Robbins and Pearce (1992) concluded that retrenchment is an integral component of successful recovery from decline. In this note we critique, replicate and provide an alternative explanation for their findings using data from the same sample of firms attempting turnarounds. Based on our analyses, we find that little evidence exists to support the assertion that retrenchment is integral to turnaround. We conclude by offering several recommendations for turnaround researchers.     

Konkrete und abstrakte Schadensberechnung in der Sachversicherung

The article deals with the question of whether the compensation owed by a property insurer is calculated according to abstract criteria or rather to the concrete expenses incurred by the policyholder in the individual case. For this purpose, the paper provides an overview of the principles of damage calculation in the fields of property insurance. In addition, the author draws a comparison between property insurance and liability law in terms of the basics of damage assessment. This particularly concerns the relationship between the so-called efficiency rule and the damaged party’s duty to minimize damages, but also the question of whether and to what extent the principles of liability law can be transferred to property insurance law. Finally, the author illustrates these principles by means of two examples from the field of vehicle insurance.     

Does Aid Effectiveness Differ per Political Ideologies?

Despite the extensive empirical literature on aid effectiveness, existing studies have not addressed directly how political ideology affects the use of foreign aid in the recipient country. This study, therefore, uses a unique dataset of 12 democratic countries in Africa to investigate the impact of political ideologies on aid effectiveness. Our results indicate that each political party uses aid differently in peruse of their political, ideological orientation. Further analyses suggest that rightist capitalist parties are likely to use aid to improve the private sector environment. Leftist socialist on the other hand, use aid effectively on pro-poor projects such as short-term poverty reduction, mass education and health services. Our additional analysis on the lines of colonialisation shows that the difference in the use of aid by political parties is much stronger in French colonies than Britain colonies. The study provides insight on how the recipient government are likely to use foreign aid.     

Cost-effectiveness of axicabtagene ciloleucel for adult patients with relapsed or refractory large B-cell lymphoma in the United States

Abstract

Purpose: Axicabtagene ciloleucel (axi-cel) was recently approved for treatment of relapsed or refractory (R/R) large B-cell lymphoma (LBCL) following two or more prior therapies. As the first CAR T-cell therapy available for adults in the US, there are important questions about clinical and economic value. The objective of this study was to assess the cost-effectiveness of axi-cel compared to salvage chemotherapy using a decision model and a US payer perspective.

Materials and methods: A decision model was developed to estimate life years (LYs), quality-adjusted life years (QALYs), and lifetime cost for adult patients with R/R LBCL treated with axi-cel vs salvage chemotherapy (R-DHAP). Patient-level analyses of the ZUMA-1 and SCHOLAR-1 studies were used to inform the model and to estimate the proportion achieving long-term survival. Drug and procedure costs were derived from US average sales prices and Medicare reimbursement schedules. Future healthcare costs in long-term remission was derived from per capita Medicare spending. Utility values were derived from patient-level data from ZUMA-1 and external literature. One-way and probabilistic sensitivity analyses evaluated uncertainty. Outcomes were calculated over a lifetime horizon and were discounted at 3% per year.

Results: In the base case, LYs, QALYs, and lifetime costs were 9.5, 7.7, and $552,921 for axi-cel vs 2.6, 1.1, and $172,737 for salvage chemotherapy, respectively. The axi-cel cost per QALY gained was $58,146. Cost-effectiveness was most sensitive to the fraction achieving long-term remission, discount rate, and axi-cel price. The likelihood that axi-cel is cost-effective was 95% at a willingness to pay of $100,000 per QALY.

Conclusion: Axi-cel is a potentially cost-effective alternative to salvage chemotherapy for adults with R/R LBCL. Long-term follow-up is necessary to reduce uncertainties about health outcomes.     

Developing an Integrative International Human Resource Model: The contribution of Chinese Multinational Enterprises

This study develops an integrative international human resource IHRM framework in Chinese MNEs mainly by examining the relationship between the intervening factors and IHRM policies and practices. It confirms that IHRM is associated with a variety of contextual and firm-specific factors, including political, legal, economic, socio-cultural factors, international strategy, organizational structure, organizational culture, stage and mode of internationalization, type and niche of industry, international experience, size of international operation, the reliance on international markets and top management perceptions of home HRM systems. These factors have differentiated impact and are changing over time. It also explores the impact of IHRM policy and practice on each other, arguing that there is interplay between IHRM policies and practices.
