The purpose of this paper is to develop a methodology for automatically determining the optimal allocation of police officers in accordance with the division and organization of labor.
The problem is defined as the problem of the goal programming for which the mathematical model of mixed integer programming was developed. In modeling of the scheduling problem the approach police officer/scheme, based on predefined scheduling patterns, was used. The approach is applied to real data of a police station in Bosnia and Herzegovina.
This study indicates that the determination of monthly scheduling policemen is complex and challenging problem, which is usually performed without the aid of software (self-rostering), and that it can be significantly facilitated by the introduction of scheduling optimization approach.
The developed mathematical model, in its current form, can directly be applied only to the scheduling of police officers at police stations which have the same or a similar organization of work.
Optimization of scheduling significantly reduces the time to obtain a monthly schedule. In addition, it allows the police stations to experiment with different forms of organization work of police officers and to obtain an optimal schedule for each of them in a short time.
The problem of optimal scheduling of employees is often resolved in other fields. To the authors knowledge, this is the first time that the approach of goal programming is applied in the field of policing.

This article examines the extent to which costs imposed on customers and other factors influence tax-motivated income shifting when corporate taxpayers expect tax rates to decline. I find that sellers of durable goods shift defer less income to lower tax rate periods than sellers of nondurable goods. This is consistent with shifting firms considering the effect of their income shifts on their customers. There is also limited evidence that firms with greater market power shift more income than other firms. In addition, I find evidence that, controlling for political costs and scale effects, smaller firms shifted more income than larger firms. This result is inconsistent with a “tax sophistication” hypothesis that larger firms are better able to engage in tax planning activities than smaller firms.

Demonstrates the application of the recently proposed shifting mean heuristic to statistical quality control situations. Proposes the heuristic search procedure primarily as a tool for retrospective (or post mortem) data analysis, retrospectively examining a known data set to establish shifts of process mean, as illustrated in the traditional Manhattan diagram (i.e. a plot of observations with superimposed sub‐process means). However, because the procedure can be operated automatically, it is suggested that where sampling rates are relatively slow it could also be used for online quality monitoring by providing a dynamic Manhattan diagram which changes shape when a newly developed series of observations establishes a shift from a pre‐specified reference level or target value. Briefly reviews other approaches to establishing shifts in process mean, describes the concepts underlying the heuristic search procedure, and reviews the statistical considerations involved. Compares the procedure with other approaches, and provides examples of the heuristic search procedure operating as a tool for retrospective data analysis using three time series kindly provided by the editor which were analysed “blind” by the author. The editor’s comments on the results are appended.

The purpose of this paper is to establish a conversation between international business and international entrepreneurship literatures by analyzing if and how international opportunities are related to the internationalization process of the firm.
This paper reports finding from a backward-looking longitudinal, qualitative, embedded case study of an internationalized Brazilian firm, covering all 13 foreign markets where the firm has operated over 18 years.
Modal shifts within foreign markets were rare. Over time, the firm learned how to refine, rather than change, the servicing modes within each foreign market; it also learned how to better develop internal and exploitative opportunities, manage a portfolio of servicing modes across foreign markets, and use more complex mode servicing packages. Overall, international opportunities and the internationalization process of the firm were inextricably connected.
The authors acknowledge limitations related to the statistical generalizability of the research method and suggest that statistical validation is needed as the research on opportunities and the internationalization process of the firm progresses.
Internationalizing firms should carefully consider the choice of entry mode in foreign markets. They should also understand that learning is not necessarily associated with change.
The authors show that the internationalization process of a traditional firm can be analyzed through an opportunity lens. This means associating characteristics of international opportunities with mode continuation and modal shifts in all foreign markets where the firm operates.
