Sociodemographic Determinants of Occupational Risks of Exposure to COVID‐19 in Canada

The activities performed by Canadian workers in some occupations may increase the risk of exposure to infectious diseases such as COVID‐19. This research note explores how occupational exposure risks vary by labor force characteristics using publicly available Canadian data in combination with a data set providing information on the level of physical proximity and frequency of exposure to infections or diseases faced by workers in different occupations. The results show important sociodemographic differences. First, women work in occupations associated with significantly higher average risks of exposure to COVID‐19 than men. This is driven by their overrepresentation in high‐risk broad occupational categories such as health occupations. Second, older workers (65 years or more), a group vulnerable to COVID‐19, appear to work in occupations requiring performing activities characterized by a lower level of physical proximity than their younger colleagues, with minimal differences in the frequency of exposure to diseases or infections. Finally, workers in low‐income occupations are employed in occupations that put them at greater risk of exposure to COVID‐19 than other workers. This is especially the case for women, immigrants, and members of visible minority groups in low‐income occupations. More broadly, this research note provides insights into the health‐related dimension of the literature on occupational tasks and labor market stratification.

PARTICIPATORY SPATIAL KNOWLEDGE MANAGEMENT TOOLS

Different types of spatial knowledge (expert, sectoral, tacit and community) are strategic resources in urban planning and management. Participatory spatial knowledge management is a major method for eliciting various types of knowledge, providing a platform for knowledge integration and informing local action and public policy. Knowledge types linked to a specific geographical locality can be integrated through geographical information systems. Recent developments in geographical information and communication technology (geoICT) have extended the opportunities for participatory spatial knowledge production, use and exchange. However, data reliability of user-generated content, social exclusion due to dependence on technology and the interpretation and implications of digital maps are major concerns. The challenge is how to integrate and utilize multiple knowledge sources for improving urban management and governance. This paper integrates the literature on knowledge types and knowledge production processes with available geoICT tools for the production, use and exchange of knowledge sources and applies it to examples from Asia, Africa and Latin America. From this review, we provide a heuristic framework for assessing the extent to which participatory spatial knowledge management tools can be instrumental on several fronts. We argue that technological developments of knowledge production have not fully addressed important issues related to accountability, empowerment, control and use of knowledge. Moreover, these developments may foster social exclusion, which could detract from the benefits of participatory spatial knowledge management in the context of urban sustainability.     

Dynamic performance of a hybrid inventory system with a Kanban policy in remanufacturing process

In this paper we study a hybrid system with both manufacturing and remanufacturing. The inventory control strategy we use in the manufacturing loop is an automatic pipeline, inventory and order based production control system (APIOBPCS). In the remanufacturing loop we employ a Kanban policy to represent a typical pull system. The methodology adopted uses control theory and simulation. The aim of the research is to analyse the dynamic (as distinct from the static) performance of the specified hybrid system. Dynamics have implications on total costs in terms of inventory holding, capacity utilisation and customer service failures. We analyse the parameter settings to find preferred “nominal”, “fast” and “slow” values in terms of system dynamics performance criteria such as rise time, settling time and overshoot. Based on these parameter settings, we investigate the robustness of the system to changes in return yield and the manufacturing/remanufacturing lead time. Our results clearly show that the system is robust with respect to the system dynamics performance and the remanufacturing process can help to improve system dynamics performance. Thus, the perceived benefits of remanufacturing of products, both environmentally and economically, as quoted in the literature are found not to be detrimental to system dynamics performance when a Kanban policy is used to control the remanufacturing process.     

Inference of a hidden spatial tessellation from multivariate data: application to the delineation of homogeneous regions in an agricultural field

Summary.  In a precision farming context, differentiated management decisions regarding fertilization, application of lime and other cultivation activities may require the subdivision of the field into homogeneous regions with respect to the soil variables of main agronomic significance. The paper develops an approach that is aimed at delineating homogeneous regions on the basis of measurements of a categorical and quantitative nature, namely soil type and resistivity measurements at different soil layers. We propose a Bayesian multivariate spatial model and embed it in a Markov chain Monte Carlo inference scheme. Implementation is discussed using real data from a 15-ha field. Although applied to soil data, this model could be relevant in areas of spatial modelling as diverse as epidemiology, ecology or meteorology.     

Quality of life in rural areas: processes of divergence and convergence

In Germany, processes can be observed that have long been out of keeping with the principle of equality of opportunity. Unemployment is concentrated in the structurally weak peripheral areas, in Eastern Germany in particular; emigration of young and better-educated people to the West is not diminishing, but contrary to expectation is again on the increase; aging processes have set in already, and when it comes to the provision of infrastructure, e.g. in the field of professional training, some regions are already suffering from considerable problems. These difficulties are frequently interpreted as differences between East and West and are explained away as problems resulting from reunification, such as the deindustrialization and restructuring of the economy and the enormous decline in the birth rate in Eastern Germany. Although these problems cannot just be attributed to social transformation and the birth rate crisis alone, being subject to more general processes of intensified globalization and the aging of society, the increasing regional disparities are rarely considered in the overall context of regional development patterns throughout Germany. Moreover, the difficulty of even obtaining data for purposes of comparison generally means that an international yardstick is lacking when regional developments are analyzed. The present study investigates regional disparities over a period of time in the light of subjective and objective indicators of the quality of life for individuals. To this end, we make use of data from the Wohlfahrtssurvey [Welfare Survey] from 1978 to 2001, among other sources. On the basis of the Euromodule that has been established at the WZB, we compare current regional patterns in Germany with those in other European countries. This approach makes it possible to provide information on the scale of regional disparities in various different countries, and to identify privileged and handicapped regions with reference to standards of living and the sense of wellbeing. The study’s findings show that, in the past 25 years, welfare in Western Germany has evened out at a higher level, but currently a trend towards increasing economic disparity is discernible. In comparison with other European countries, on the other hand, the differences (regional differences) within Germany are comparatively slight.     

Predicting Indonesian Journalists' Use of Public Relations-Generated News Material

Abstract

The news media are the main channel for public relations practitioners to get messages across to their publics. In recent years, little research was conducted on predicting journalists' use of public relations news material. As the largest Southeast Asian and the world's most populous Muslim nation, Indonesia presents a complex media and public relations environment. This study found fundamental tenets in journalism, however, which remain the most important factors in predicting the use and acceptance of public relations-generated news materials. At the same time, however, business interests have highly significant effect on journalists. Informal relations can also influence their use.     

The Leningrad Martyrology: A Statistical Note on the 1937 Executions in Leningrad City and Region

This article examines the August-December 1937 executions of the Great Terror in Leningrad city and region. The work is based on a sample of 784 out of 16,062 listings of victims available in volumes 1 through 4 of Leningradskii martirolog, a recent archive-based publication, and on the results of the 1937 and 1939 all-Union censuses. The victims are analyzed by ethnicity, birthplace, age, occupation, status and party membership. This analysis suggests that executions hit those individuals designated as non-Russians, above all the Poles, especially hard. Middle-aged persons were the most frequent execution target, compared to a low proportion of people under 20 and a relatively large share of seniors. Individuals of lower social standing and occupational skills comprised the majority of the victims, even though government administrators and the intelligentsia figured noticeably among the executed. Party members probably suffered more heavily than the rest of the population; yet their status and occupations did not neatly fit a notion of social elite. Overall, this article confirms the importance of the ethnic dimension of the terror revealed in recent historiography. The article shows the elite as a secondary target of the August-December 1937 executions or at least suggests that the understanding of a Soviet elite needs refinement.
