Olivier Berthod, Michael Grothe-Hammer, and Jörg Sydow report an unconventional research design using multi-site ethnography. The aim is to study inter-organizational relationships, which are not well understood, and are not addressed by single-site ethnographic methods. Ethnography is a popular and established methodology in organization studies. However, organizing is a process that crosses boundaries, and the traditional approach that involves immersing the ethnographer in one defined social or organizational setting means that inter-organizational phenomena are overlooked. The challenge is to conduct fieldwork at multiple sites, across which inter-organizational relations may be conducted with varying degrees of formality, and be more or less visible. Inter-organizational ethnography thus builds on the combination of several techniques. Four techniques are explored: following boundary objects, capturing network enactments, using several investigators, and repeat interviews. The methodology is illustrated with a study of the network of eighty organizations that deal with large-scale crises and emergencies in Düsseldorf.

This edited volume, Research in Deaf Education: Contexts, Challenges, and Considerations, provides readers with critical foundational information with which to view contemporary research in deaf education. Deaf education as a field is experiencing a high degree of turnover in its researchers, as well as major shifts in how deaf individuals access information and engage with society as a whole. To conduct research in deaf education includes a need to be mindful of the influence of context as well as the challenges of conducting research with a low-incidence and diverse population. Together with a chapter on history, as well as how the population has changed in recent decades, chapters in this book seek to provide readers with important context and strategies for the implementation of a range of research methodologies. Deaf education research utilizes a great range of research methodologies, and while this volume does not address all possible approaches, it does cover diverse research perspectives, from action research to large-scale surveys to multi-level modeling. In addition, several chapters in this volume address issues that are related to research measures themselves, particularly those that incorporate multiple communication modalities in their content or design. The volume concludes with a thematic analysis of the volume as a whole, offering cross cutting perspectives on how deaf education as a field can move forward in a responsive, ethical, authentic, and rigorous manner.

Is large-scale immigration to Europe incompatible with the continent’s generous and encompassing welfare states? Are Europeans willing to share welfare benefits with ethnically different and often less well-off immigrants? Or do they regard the newcomers as undeserving and their claim for welfare rights as unjustified? These questions are at the heart of what has become known as the “New Progressive Dilemma” (NPD) debate—and the predominant answers given to them are rather pessimistic. Pointing to the experiences of the US, where a multi-racial society in combination with a longstanding history of immigration encounters very limited welfare provision, many Europeans fear that the continent’s new immigrant-based heterogeneity may push it toward more American levels of redistribution. But are the conflictual US experiences really reflected in the European context? Immigration and Welfare State Retrenchment addresses this question by connecting the New Progressive Dilemma debate with comparative welfare state and party research in order to analyze the role ethnic diversity plays in welfare reforms in the US and Europe. Whereas the combination of racial patterns and party politics had and still has serious consequences for the US welfare system, the general message of the book is that these are not echoed in the Western European context. In addition, while many Europeans are very critical of immigration and prepared to ban immigrants from welfare benefits, both the institutional design of European welfare programs and the economically divided anti-immigrant movement prevent immigration concerns from translating into actual retrenchment in the core areas of welfare.

Defying the conventional split between “theory” and “methodology,” this book introduces a yet unarticulated and thus far never systematized method of theorizing designed to reveal abstract social patterns. Insisting that such methodology can actually be taught, it tries to make the mental processes underlying the practice of a “concept-driven sociology” more explicit. Many sociologists tend to study the specific, often at the expense of also studying the generic. To correct this imbalance, the book examines the theoretico-methodological process by which we can “distill” generic social patterns from the culturally, historically, and situationally specific contexts in which we encounter them. It thus champions a “generic sociology” that is pronouncedly transcontextual (transcultural, transhistorical, transsituational, and translevel) in its scope. In order to uncover generic, transcontextual social patterns, data need to be collected in a wide range of social contexts. Such contextual diversity is manifested multi-culturally, multihistorically, multisituationally, as well as at multiple levels of social aggregation. True to its message, the book illustrates generic social patterns by drawing on numerous examples from diverse cultural contexts and historical periods and a wide range of diverse social domains, as well as by disregarding scale. Emphasizing cross-contextual commonality, generic sociology tries to reveal formal “parallels” across seemingly disparate contexts. This book features the four main types of cross-contextual analogies generic sociologists tend to use (cross-cultural, cross-historical, cross-domain, and cross-level), disregarding conventionally noted substantive differences in order to note conventionally disregarded formal equivalences.

Hard coal mining is characterised by features that pose numerous challenges to its current operations and cause strategic and operational problems in planning its development. The most important of these include the high capital intensity of mining investment projects and the dynamically changing environment in which the sector operates, while the long-term role of the sector is dependent on factors originating at both national and international level. At the same time, the conditions for coal mining are deteriorating, the resources more readily available in active mines are being exhausted, mining depths are increasing, temperature levels in pits are rising, transport routes for staff and materials are getting longer, effective working time is decreasing, natural hazards are increasing, and seams with an increasing content of waste rock are being mined. The mining industry is currently in a very difficult situation, both in technical (mining) and economic terms. It cannot be ignored, however, that the difficult financial situation of Polish mining companies is largely exacerbated by their high operating costs. The cost of obtaining coal and its price are two key elements that determine the level of efficiency of Polish mines. This situation could be improved by streamlining the planning processes. This would involve striving for production planning that is as predictable as possible and, on the other hand, economically efficient. In this respect, it is helpful to plan the production from operating longwalls with full awareness of the complexity of geological and mining conditions and the resulting economic consequences. The constraints on increasing the efficiency of the mining process are due to the technical potential of the mining process, organisational factors and, above all, geological and mining conditions. The main objective of the monograph is to identify relations between geological and mining parameters and the level of longwall mining costs, and their daily output. In view of the above, it was assumed that it was possible to present the relationship between the costs of longwall mining and the daily coal output from a longwall as a function of onerous geological and mining factors. The monograph presents two models of onerous geological and mining conditions, including natural hazards, deposit (seam) parameters, mining (technical) parameters and environmental factors. The models were used to calculate two onerousness indicators, Wue and WUt, which synthetically define the level of impact of onerous geological and mining conditions on the mining process in relation to: —— operating costs at longwall faces – indicator WUe, —— daily longwall mining output – indicator WUt. In the next research step, the analysis of direct relationships of selected geological and mining factors with longwall costs and the mining output level was conducted. For this purpose, two statistical models were built for the following dependent variables: unit operating cost (Model 1) and daily longwall mining output (Model 2). The models served two additional sub-objectives: interpretation of the influence of independent variables on dependent variables and point forecasting. The models were also used for forecasting purposes. Statistical models were built on the basis of historical production results of selected seven Polish mines. On the basis of variability of geological and mining conditions at 120 longwalls, the influence of individual parameters on longwall mining between 2010 and 2019 was determined. The identified relationships made it possible to formulate numerical forecast of unit production cost and daily longwall mining output in relation to the level of expected onerousness. The projection period was assumed to be 2020–2030. On this basis, an opinion was formulated on the forecast of the expected unit production costs and the output of the 259 longwalls planned to be mined at these mines. A procedure scheme was developed using the following methods: 1) Analytic Hierarchy Process (AHP) – mathematical multi-criteria decision-making method, 2) comparative multivariate analysis, 3) regression analysis, 4) Monte Carlo simulation. The utilitarian purpose of the monograph is to provide the research community with the concept of building models that can be used to solve real decision-making problems during longwall planning in hard coal mines. The layout of the monograph, consisting of an introduction, eight main sections and a conclusion, follows the objectives set out above. Section One presents the methodology used to assess the impact of onerous geological and mining conditions on the mining process. Multi-Criteria Decision Analysis (MCDA) is reviewed and basic definitions used in the following part of the paper are introduced. The section includes a description of AHP which was used in the presented analysis. Individual factors resulting from natural hazards, from the geological structure of the deposit (seam), from limitations caused by technical requirements, from the impact of mining on the environment, which affect the mining process, are described exhaustively in Section Two. Sections Three and Four present the construction of two hierarchical models of geological and mining conditions onerousness: the first in the context of extraction costs and the second in relation to daily longwall mining. The procedure for valuing the importance of their components by a group of experts (pairwise comparison of criteria and sub-criteria on the basis of Saaty’s 9-point comparison scale) is presented. The AHP method is very sensitive to even small changes in the value of the comparison matrix. In order to determine the stability of the valuation of both onerousness models, a sensitivity analysis was carried out, which is described in detail in Section Five. Section Six is devoted to the issue of constructing aggregate indices, WUe and WUt, which synthetically measure the impact of onerous geological and mining conditions on the mining process in individual longwalls and allow for a linear ordering of longwalls according to increasing levels of onerousness. Section Seven opens the research part of the work, which analyses the results of the developed models and indicators in individual mines. A detailed analysis is presented of the assessment of the impact of onerous mining conditions on mining costs in selected seams of the analysed mines, and in the case of the impact of onerous mining on daily longwall mining output, the variability of this process in individual fields (lots) of the mines is characterised. Section Eight presents the regression equations for the dependence of the costs and level of extraction on the aggregated onerousness indicators, WUe and WUt. The regression models f(KJC_N) and f(W) developed in this way are used to forecast the unit mining costs and daily output of the designed longwalls in the context of diversified geological and mining conditions. The use of regression models is of great practical importance. It makes it possible to approximate unit costs and daily output for newly designed longwall workings. The use of this knowledge may significantly improve the quality of planning processes and the effectiveness of the mining process.
