Well-designed and executed experiments prove cause-and-effect relationships. The ability to draw causal conclusions is critical to knowledge development in any field of research. In this article, we discuss the benefits of experimental designs over alternative research approaches for the social sciences, discuss advantages and disadvantages of different types of experiments, review existing experimental studies specific to tourism and hospitality, and offer guidance to researchers who wish to conduct such studies. Properly executed experiments using actual behaviour of real stakeholders as a dependent variable lead to conclusions with high external validity. Our discussion of practical implementation issues culminates in a checklist for researchers. The article launches the Annals of Tourism Research Curated Collection on experimental research in tourism.

The creation of energy-saving turbogenerators is an essential component of the development of small energy systems. The gradual growth of interest in distributed electricity generation necessitates the constant improvement of these units. Moreover, they implement a more environmentally friendly generation method than when using microturbine units that use fuel to carry out the work process. Nowadays, turbogenerators are created based on different types of expansion machines, which have their advantages and disadvantages, given in this article. Compared to competitors, vortex expansion machines have good prospects and the necessary potential to expand their research and produce turbogenerators. An experimental vortex expansion machine with a peripheral-lateral channel and ability to change the geometric parameters of its flowing part was created to meet these needs. Experimental studies of the machine were performed on a special stand with air as a working fluid. As a result of the tests, the data were successfully obtained and processed. They are presented in the form of tables and graphical dependencies. The nature of the influence of thermodynamic parameters and geometric parameters of the flow part on the efficiency of the vortex expansion machine and turbogenerator based on it to further improve and create new turbogenerators is clarified.

Intersektionalitetsbegrebet indebærer, at sociale differentieringsformer som køn, klasse, etnicitet og ”race” er gensidigt konstituerende både på et identitetsmæssigt og strukturelt niveau. Begrebet har haft stor gennemslagskraft og bidraget positivt til fornyelse af dansk og international kønsforskning. Da begrebet rummer potentialer til analyser af komplekse sociale differentieringer, er det imidlertid også relevant for en bredere sociologi. Nutidige højt differentierede samfund fordrer således begreber og metodologier, som er egnede til at gribe kompleksitet. Intersektionalitetstænkningen har teorihistoriske rødder i amerikansk sort standpunktsfeminisme. I Danmark blev begrebet først anvendt af poststrukturalistiske socialpsykologer, som gentænkte det og gjorde det velegnet til at analysere, hvordan komplekse identiteter skabes i hverdagslivet. Senere er begrebet blevet anvendt af kønsforskere med andre faglige og videnskabsteoretiske udgangspunkter. I artiklen fremhæves det, at intersektionalitetsbegrebet kan anvendes til at producere forskellige typer sociologisk viden. I den forbindelse præsenteres en typologi over forskellige tilgange til intersektionalitetsanalyser, som bruges som afsæt til at skitsere tre eksempler på analyser af social ulighed og eksklusion. ENGELSK ABSTRACT: Sune Qvotrup Jensen and Ann-Dorte Christensen: Inter-sectionality as a Sociological Concept Contemporary highly differentiated societies require concepts and methodologies which are suited for grasping complexity. Intersectionality is a fruitful approach to analyze this complexity because social forms of differentiation such as gender, class, ethnicity and “race” are understood as mutually co-constructing at the level of individual identities and at the level of social structures. Intersectionality is a travelling concept which is theoretically rooted in black American feminism. In Denmark, the concept was first used by post-structuralist social psychologists, who adapted it to analyzing how complex identities were created in everyday life. Later on the concept was later taken up by gender researchers within the social sciences. This article analyses how the concept of intersectionality can be used to produce different types of sociological knowledge. It introduces a typology of approaches to intersectionality analyses, which serves as the backdrop for three examples of analyses of social inequality and exclusion. Key words: Intersectionality, complexity, social differentiation, gender, class, ethnicity.

Abstract This article explores the current literature on ‘research impact’ in the social sciences and humanities (SSH). By providing a comprehensive review of available literature, drawing on national and international experiences, we take a systematic look at the impact agenda within SSH. The primary objective of this article is to examine key methodological components used to assess research impact comparing the advantages and disadvantages of each method. The study finds that research impact is a highly complex and contested concept in the SSH literature. Drawing on the strong methodological pluralism emerging in the literature, we conclude that there is considerable room for researchers, universities, and funding agencies to establish impact assessment tools directed towards specific missions while avoiding catch-all indicators and universal metrics.

AbstractIn recent years, experimental methods have been both highly celebrated, and roundly criticized, as a means of addressing core questions in the social sciences. They have received particular attention in the analysis of development interventions. This paper focuses on two key questions: (1) what have been the main contributions of RCTs to the study of government performance? and (2) what could be the contributions, and relatedly the limits? It draws inter alia on a new systematic review of experimental and quasi-experimental studies on governance to consider both the contributions and limits of RCTs in the extant literature. A final section introduces the studies included in this symposium in light of this discussion. Collectively, the studies push beyond polarized debates over experimental methods towards a new middle ground, considering both how experimental work can better address identified weaknesses and how experimental and non-experimental techniques can be combined most fruitfully.

The article consists of three main sections, in which I successively discuss the nature and role of realization, interpretation and abstraction in experimental and observational processes. In this way, these sections address several fundamental problems in philosophy of science, ontology and epistemology, and philosophy of language. Section 1 introduces the notion of realization processes, and argues that successful realization requires causal judgments. The second section discusses the role of conceptual interpretation in experiments and observations, explains how realization and interpretation can be distinguished, and emphasizes the significance of different types and ranges of experimental and observational reproducibility. It also includes a subsection on the issue of reproducibility in contemporary social sciences and psychology. Section 3 explains how concepts are abstracted from existing realization processes, and concludes that abstraction bestows a nonlocal meaning on these extensible concepts. In addition, I discuss and criticize some rival views of abstraction and concept meaning (to wit, mentalism and localism). The article concludes with some observations on the notion of a (cognitive) trinity.In my reply, I respond to the points raised in the six commentary papers. The following issues are addressed: the place of causality in physics (Steffen Ducheyne), perception in ordinary life (Monica Meijsing), the role of reproducibility in psychology and the social sciences (Daniël Lakens, Ruud Abma), the significance and implications of conceptual innovation (Lieven Decock), and the relationship between meaning, communication and ontology (Martin Stokhof and Michiel van Lambalgen).

The study of ethnic riots has a substantial pedigree in the social sciences, but so far there has been no systematic attempt to unify insights from scholars working on different areas of the world, nor has there been any extensive application of existing knowledge to the study of Western Europe. We address these two lacunae by drawing on contemporary scholarship to generate testable hypotheses about state responses to ethnic riots in liberal democracies, and by conducting a preliminary test of these hypotheses on four controlled comparison cases from Britain and France. Our cases reveal that states employ a relatively even balance of repression and accommodation in keeping with thesocial controlperspective, but that the precise balance is affected by theelectoral incentivesof the party in power. This evidence suggests the external validity of findings by Fording (2001) – who emphasizes the significance of social control in the American context – and Wilkinson (2004) – who stresses the importance of electoral incentives in the Indian environment – but it implies that these separate insights may be more powerful in combination. Our study also demonstrates the limitations of perspectives that predict either simple repression or accommodation of rioters, and of those that emphasize distinctive national responses to riots.

The introduction of qualitative naturalistic research—qualitative research within the paradigm of naturalistic inquiry—into a scholarly tradition that historically has been positivistic has caused concern and controversy among both naturalists and logical positivists in the social sciences. The purpose of this article is to attempt to establish legitimate and fair criteria for the publication of qualitative naturalistic research in occupational therapy. Traditional criteria from the paradigm of logical positivism emphasizing internal validity and external validity are reviewed, and parallel criteria for qualitative naturalistic research, such as credibility and transferability, are examined. Methods such as triangulation, negative case analysis, and testing for rival hypotheses appear to show promise as criteria of fairness and rigor for publication of qualitative naturalistic research in occupational therapy.

Natural experiments help to overcome some of the obstacles researchers face when making causal inferences in the social sciences. However, even when natural interventions are randomly assigned, some of the treatment–control comparisons made available by natural experiments may not be valid. We offer a framework for clarifying the issues involved, which are subtle and often overlooked. We illustrate our framework by examining four different natural experiments used in the literature. In each case, random assignment of the intervention is not sufficient to provide an unbiased estimate of the causal effect. Additional assumptions are required that are problematic. For some examples, we propose alternative research designs that avoid these conceptual difficulties.

AbstractSurvey experiments have become a central methodology across the social sciences. Researchers can combine experiments’ causal power with the generalizability of population-based samples. Yet, due to the expense of population-based samples, much research relies on convenience samples (e.g. students, online opt-in samples). The emergence of affordable, but non-representative online samples has reinvigorated debates about the external validity of experiments. We conduct two studies of how experimental treatment effects obtained from convenience samples compare to effects produced by population samples. In Study 1, we compare effect estimates from four different types of convenience samples and a population-based sample. In Study 2, we analyze treatment effects obtained from 20 experiments implemented on a population-based sample and Amazon's Mechanical Turk (MTurk). The results reveal considerable similarity between many treatment effects obtained from convenience and nationally representative population-based samples. While the results thus bolster confidence in the utility of convenience samples, we conclude with guidance for the use of a multitude of samples for advancing scientific knowledge.

Our social norms and moral values shape our beliefs about the propriety of different types of market exchanges. This review considers social and moral influences on beliefs about property and the consequences of these beliefs for the legal regulation of property. The focus is mainly on empirical evidence from social psychology, with additions from related areas like cognitive psychology, behavioral economics, and other social sciences. After briefly reviewing empirical findings on perceptions of property at the level of the individual person, I examine how social relationships shape perceptions about ownership and exchange of property, as well as the boundaries of the broad category of property. Finally, I explore one important type of socially embedded property—the home—and how social psychological conceptions of property as embedded in social relationships have clashed with the development of the legal doctrine of eminent domain.
