Combination of evidence from multiple administrative data sources: quality assessment of the Austrian register‐based Census 2011

This article investigates the quality of register data in the context of a standardized quality framework. The special focus of this work lies on the assessment of census data and how to deal with uncertainty that arises from multiple sources (registers). To take the uncertainty associated with support and conflict between several registers into account, Dempster–Shafer's theory of evidence is applied. This ‘fuzzy’ approach allows us to investigate the quality of databases with multiple underlying sources for a single attribute and to provide both quality measures and plausibility intervals.     

Organizational Size, Structure, and Efficiency: A Test of a Blau-Hage Model

A bstract . Combining the work of Peter Blau and Jerald Hage regarding organizational characteristics and efficiency, a correlational model was constructed consisting of testable propositions relating organizational size, complexity, stratification, formalization, centralization , and two measures of efficiency. The model was also extended to include hierarchical levels, after vertical and horizontal measures of complexity were separated. Following an extensive review of the literature, both official and self-reported data from one type of economic organization ( 104 savings and loan associations in New York State ) were employed to test the propositions in a profit-oriented context. While we findings demonstrate limited support for the model in this special type to economic organization (five of thirteen propositions were fully or partly supported by the analysis), a further classification and comparison of studies reviewed, according to the type of organization under study, suggests that a unified theory encompassing both economic and non-economic organizations is feasible.     

Training and organisational performance: A meta‐analysis of temporal,institutional and organisational context moderators

Drawing on systems theory, we conducted a moderated meta‐analysis of the training and organisational performance relationship using 119 primary studies. We examined the moderating effects of quality versus quantity of training, time, institutional and organisational context factors in the relationship between training and organisational performance. Our findings reveal that training is positively and directly related to organisational performance with no statistically significant difference between measures of training quality and quantity. We found that the relationship was stronger over time and that country performance orientation and country labour cost moderate the training and organisational performance relationship. We found no evidence for the moderating effects of the three organisational context moderators we examined (i.e. industry sector, organisational size and technology intensity). Finally, our results reveal that training type (i.e. general or firm‐specific) does not moderate the training and organisational performance relationship.     

Job preferences as revealed by employee-initiated job changes

Many previous studies try to discover job preferences by directly asking individuals. Since it is not sure whether answers to these surveys are relevant for actual behaviour, this empirical examination offers a new approach based on representative German data. Employees who quit their job and find a new one compare the two jobs with respect to eight job characteristics: type of work, pay, chances of promotion, work load, commuting time, work hour regulations, fringe benefits and security against loss of job. It is argued that the observation of many improvements (and few declines) for a certain attribute indicates a particular relevance and high preference for this attribute. It turns out that pay and type of work are most important for employees in this sense. Differences across subgroups of employees with respect to individual characteristics, such as sex and age, are explored. Those between East and West Germany diminish over time.     

煤质化验的误差控制的几点思考

对于所有的煤质化验工作而言,第一步首先就要采取煤样,对煤样的采取工作是整个煤质化验过程中,最为重要的一个环节。在实际操作过程中,有很多因素都会让采煤产生一定误差。因为煤的特性极为不均匀,所以很容易造成误差。既然误差是无法避免的,那么我们就应该采取相应的措施,从根本上极力减小误差的出现。     

UK Intra-industry Trade with the EU North and South

This paper tests the traditional country and industry hypotheses of intra-industry trade (IIT) in vertically and horizontally differentiated products in the context of the UK's bilateral trade with EU countries. It distinguishes empirically between IIT in vertically and horizontally differential goods, between trade with EU 'North' and 'South' and between the effects of using GDP proxies and direct measures of national factor endowment differences. The paper shows that the robustness of the results of earlier multi-country studies are open to challenge, that the separation of IIT into vertical and horizontal IIT offers an important innovation to the empirical work in this area and that further development of large numbers models of IIT in quality differentiated goods is required.     

A classification and evaluation of research in operations management

It is important that the first issue of a new journal devoted to research in a given subject area examine the general nature of research in the field at present, and indicate what type of research might be beneficially undertaken in the field in the future. It is also desirable for a new journal to consider the ways in which it will judge the general quality of its articles in the aggregate, relative to established journals in similar disciplines. That is, what criteria can and should be used, say five years hence to determine if the journal is a strong one? It is the purpose of this paper to consider these distinct, but interrelated questions. This will be done by classifying some recent OM research, commenting on what appear to be broad areas where more work might be done, and then suggesting some measures we might want to think about for evaluating papers published by the JOM in the future.     

Measuring the quality of managerial learning on the job

This article describes the development of an instrument to measure the quality of managerial learning on the job. The instrument can be used to analyse the quality of the individual learning process on the job. The literature shows that two factors determine the quality of the learning process: the learning potential of the job context and the way in which the manager approaches their work. So the instrument has two components. The first component measures the four types of work experience that offer potential opportunities for individual learning. These are transitions, task-related characteristics, obstacles and support. The second component, the so-called learning behaviour, analyses the way the individual approaches the potential learning opportunities present in the job. This can also be divided into four categories: emergent learning, planned learning, instruction-oriented learning and meaning-oriented learning. Based on these two components, an instrument has been developed to measure the quality of learning on the job. This has been shown to be valid and reliable in a sample of European managers.     

Social indicators and social accounts

This paper defines “social indicators” as statistics which have two denning characteristics. They are, first, measures of direct normative interest; that is, what the economist would call measures of “welfare” and “illfare”. Most existing government statistics are not of this type, because a large proportion of existing statistics are measures of government or other institutional activity, produced as a by-product of accounting or administrative routine. The second defining characteristic of a social indicator is that it should fit into a systematic scheme of classification or aggregation which would make possible a balanced assessment of socio-economic progress or retrogression in some broad area, as well as disaggregated and detailed study of particular problems.

The work in government on social indicators was designed in part to meet the needs of Toward a Social Report, a preliminary study of the condition of American society issued by the U.S. Department of Health, Education, and Welfare (Superintendent of Documents, Wash. D.C. 20402; 1969). Social indicators can also fit, with other statistics, into a set of “policy accounts” or scheme of social accounting, which would relate social expenditures to the social indicator they were designed to affect. This would encourage broadened cost-benefit analysis and rational public decision-making.
