Impact factor as a metric to assess journals where OM research is published

This paper investigates impact factor as a metric for ranking the quality of journal outlets for operations management (OM) research. We review all prior studies that assessed journal outlets for OM research and compare all previous OM journal quality rankings to rankings based on impact factors. We find that rankings based on impact factors that use data from different time periods are highly correlated and provide similar rankings of journals using either two-year or five-year assessment periods, either with or without self-citations. However, some individual journals have large rank changes using different impact factor specifications. We also find that OM journal rankings based on impact factors are only moderately correlated with journal quality rankings previously determined using other methods, and the agreement among these other methods in ranking the quality of OM journals is relatively modest. Thus, impact factor rankings alone are not a replacement for the assessment methods used in previous studies, but rather they evaluate OM journals from another perspective.     

An Assessment of the Within-Year Seasonality in the Loan Loss Provisioning Behavior of European Banks

This study aims at assessing whether a significant within-year seasonality exists in the loan loss provisioning behavior of European listed banks observed in the period from 2004 to 2013. Since the accuracy of auditing processes and the level of disclosure requirements in financial reports differ among quarters, during the year, banks may have a leeway to underestimate and postpone the complete provisioning of loan losses in the less regulated and less audited quarters. We hypothesize that those differences are relevant factors which determine non-lower or significantly higher average levels of loan loss provisions in the half-yearly and especially in the annual financial reports than in the interim management statements disclosed in the first and the third quarters of the year. We also investigate the impact of the recent financial crisis and develop a special analysis for the ltalian banks＇ case. The empirical results support our hypotheses, suggesting that, in some cases, a convergence among quarterly levels of auditing processes and disclosure requirements may be needed. Our work contributes to the existing literature by providing additional evidences and considerations on the within-year seasonality in the loan loss provisioning behavior of European listed banks observed in the last decade.     

Rational drug use in hospital settings – areas that can be changed

Abstract

Irrational use of drugs occurs at all levels of healthcare. This phenomenon can also be observed in hospitals. Irrational use of a drug contributes to a decrease in the patient's quality of treatment and often causes negative health consequences. For this reason, it is essential to consider methods that can be introduced in hospitals to increase the safety and effectiveness of the drugs used. The article presents selected methods of rationalization of drug management that can be used in hospitals.     

Risk behavior in the presence of government programs

Our paper assesses the impacts of the 1996 US Farm Bill on production decisions. We apply the expected utility model to analyze farmers’ behavior under risk and assess how farmers’ production decisions change in the presence of government programs. Specifically, we empirically evaluate the relative price and the risk-related effects of farm policy changes at the intensive margin of production, as well as the extra value that these policies add to farmers’ certainty equivalent. We use farm-level data collected in Kansas to estimate the model. We find evidence that decoupled government programs have only negligible impacts on production decisions.     

An evaluation of the management of the Finnish employment service

This paper analyses the efficiency of the Finnish Employment Service's management in selecting unemployed individuals who are offered a job. The database used considers short-term unemployed individuals who face the same labour market conditions in 1996. Duration analysis with a Weibull model has been performed in order to study the determinants of the transition probability from unemployment into employment and the impact of receiving job offers through the Employment Service (ES). In order to carry this out, it has been taken into account that the reception of such job offers may be endogenous because the ES selects the individuals who will receive the offers. The empirical results suggest that the decisions made by the ES are adequate in the sense that they increase the benefit of society, compared with a random assignment of the vacancies offered through the ES. Moreover, the effects of the other determinants depend on whether the individual receives offers. The results also point out that individuals who receive no offers through the ES are more likely, as time passes by, to be discouraged in searching for a job than those who do.     

Price transmission and asymmetric adjustment in the Spanish dairy sector

Asymmetric threshold vector error correction models are applied to monthly price data to analyse price relationships and patterns of transmission among farm and retail markets for a variety of dairy products in Spain. The results suggest that asymmetries affect a conspicuous part of the raw milk processed in Spain. Implications for the organizational structure of Spanish dairy markets are offered.     

Job exit of men: new job destination versus unemployment destination

Job exit of men over the age of forty is described and analysed using monthly observations derived from the 1988-89 UK Retirement Survey. A competing risks model is described and estimated. The results show that tenure and age determine transitions from a job to a new one, whereas those transitions from a job to unemployment are also determined by business cycle variables.     

Verhalten optimistisch

Information about music rank highest among the most popular media issues. With their information, music journalists contribute considerably to the media’s cultural basic services. However, there is a lack of reliable data on these specialists, their everyday work, their professional satisfaction, their self-conception as well as their role in society. The present study aims at closing this gap in communicator research. Additionally, we ask how music journalists anticipate their future in a changing media world which provides manifold other ways to gain information on music. The results of the unrepresentative online survey (n?=?209) show that today’s music journalists are relaxed about their professional situation and do not question the necessity of their job. Above all, they consider themselves to be information brokers with a subjective and critical demand for autonomy who unwaveringly believe that the review is the most important form of knowledge transfer. Also, a surprising consent is revealed between journalists reporting on entertaining music and journalists reporting on classical music as well as between newspaper and online journalists.
