Operations Analysis comes to education too highly recommended to be ignored, after having grown into wide usefulness in industry and government. Reservations about its use stem from the differences between industry and education. As the practitioners of Operations Analysis grew in numbers and experience, they became recognized agents in the constantly necessary changes in industry. Education, now lacking well-defined roles for Operations Analysis, might well seek the help of the private sector in using its tools. The pitfalls to be avoided, however, are: decision-making when only information is called for; problem definitions which yield triviality or over-generality; and failure to communicate convincingly to decision-makers. Operations Analysis can fail seriously when it starts from bad data or dubious premises, as well as when it uses ready-made methods without adaptation, or-worst of all-performs in a vacuum. 相似文献

This package performs specialized tasks related to specification, estimation, prediction and diagnostic checking in the context of a particular class of unobserved-components models. It is menu-driven and easy to use. Although the present (first) release suffers from a number of limitations, omissions and bugs, it is nevertheless a useful tool in the hands of a knowledgeable user. 相似文献

The resource‐based view (RBV) of the firm has focused attention on the importance of aligning employees' needs with the requirements of the jobs they do. This article focuses on how these needs and requirements interact in terms of learning. It does so in two ways. First, it develops new survey instruments to capture the learning demands of jobs and the learning dispositions of workers and uses them for the first time in a survey of 2,810 employees. Second, it examines how these person and job characteristics correlate with specific aspects of job satisfaction and job‐related well‐being. The results show that although learning alignment is associated with high levels of satisfaction and well‐being, not all learning misalignments are associated with the reverse. 相似文献

In this study we investigate what software development project team members consider to be a good project manager. Previous research has been carried out using project manager self‐assessments, other project stakeholder views, or recruiters’ views. This qualitative study used the repertory grid technique to identify the characteristics that project team members associate with a good project manager. This technique has been adopted because of its strength in eliciting personal constructs. Among the 18 characteristics identified, the seven most relevant were classified and compared with previous findings, which reveals differences between the team members’ and project managers’ and other stakeholders’ perceptions. Those findings complement the existing skill set and could be considered when recruiting and training project managers and staffing projects. 相似文献

Empirical evidence from road safety literature suggests that vehicular speed is an important risk factor in the incidence and severity of road traffic crashes globally. Speed studies are at rudimentary stages in developing countries, thus making vehicular speed research imperative. The main aim of the study was to establish two major speed parameters, namely, the mean and dispersion, and their implications for more extensive and long-term speed monitoring in Ghana. Research workers stationed themselves in a parked car and used a radar gun to unobtrusively measure the travelling speeds of 28,489 vehicles at 15 different inter-urban locations on three highway categories. Excessive speeding is very pervasive on all highway categories in Ghana. Travelling speeds through settlements where a speed limit of 50 km/hour is mandatory were particularly excessive. Generally, 98%, 90% and 97% of vehicles exceeded the posted speed limit of 50 km/hour on national, inter-regional and regional roads respectively. Mean speeds and speed dispersions (as assessed by the standard deviations) through built-up areas were 81.3 +/- 17.3 km/hour on national roads, 64.7 +/- 12.3 km/hour on inter-regional roads and 72.6 +/- 13.4, km/hour on regional roads. On rural undivided highways with an 80 km/hour speed limit, mean and speed dispersions were 90 +/- 18.9 km/hour on national roads, 80.1 +/- 16 km/hour on inter-regional roads and 84.4 +/- 15.6 on regional roads; also translating into 66%, 47% and 60% of vehicles exceeding recommended speeds. In all cases, speed dispersions were notably higher than the value of 10 km/hour generally found in developed countries. Excessive speeding and wide speed dispersions are highly prevalent on Ghana's highways. These factors likely account for the high incidence of traffic crashes and fatalities in Ghana. An integrated speed monitoring and control programme and by-passing small and medium settlements would be required for the reduction of speed-related crashes, fatalities and injuries. 相似文献

We study dictator allocations using a 2×2 experimental design that varies the level of anonymity and the choice set, allowing observation of audience effects in both give and take frames. Changes in the distribution of responses across treatment cells allow us to distinguish among alternative motives as elaborated in recent theory. We observe significant audience effects that vary by both frame and gender. The pattern of responses suggests that heterogeneous concerns for reputation and self-signaling across gender give rise to the contextual effects associated with the give and take frames that have previously been observed in the literature. 相似文献

This article examines the historical developments of the institutionalist theory of the business enterprise since the early 1900s in order to demonstrate its distinctive characteristics that are often overlooked or belittled by some institutional-evolutionary economists and most mainstream economists. I argue that the institutionalist theory is an evolving and emergent theory, which bears a reciprocal, evolutionary, and cumulative relationship between the business enterprise and society. The institutionalist theory is, therefore, suitable for the understanding of the real-world business enterprise as it can be modified and refined along with the evolution of capitalism. The article begins with a discussion of the present state of the institutionalist theory. The following section is devoted to the major contributions to the institutionalist theory situated in the evolution of U.S. capitalism. The penultimate section provides a critical discussion of new institutional and evolutionary approaches to the firm. The article concludes with a brief discussion as to what should be done for the further development of the institutionalist theory of the business enterprise. 相似文献
