Parametric Regression Models

Parametric regression models became the dominant tool of quantitative sociology. This dominance is not without its challenges and many criticisms have been expressed, both statistically and epistemologically. Still, the development of data mining, and then of machine learning, has led to the emergence of methodological approaches that make it possible to overcome most of the limitations of parametric regression models, for the various types of use that are of interest to the social sciences. We argue that recursive partitioning in particular may be highly vauable for social sciences. Indeed, this approach has a number of technical advantages over parametric regression and, above all, it is consistent with a conception of social determinations in terms of configurations of interdependent factors (and not of additions of independent factors). In a second step, we review a range of tools for interpreting the results obtained from recursive partitioning algorithms. Together, they form a very complete toolbox for the social sciences and show that recursive partitioning is no longer a black box as soon as the appropriate interpretative tools are mobilized. Finally, we illustrate the methods presented using sociological examples from the world of cinema. In doing so, we will show that these methods make it possible to deal with the different types of problems that arise in the social sciences when parametric regressions are usually used, in this case the study of structure effects and the ranking of explanatory factors.

This study reviews the recent quantitative and qualitative evidence on the need to develop our natural environments for creative and leisure purposes. Previous studies described the problem of tourism to be a universal one, as virtually all countries are faced with the problem of providing inadequate tourism for their citizens. In Nigeria urban centres the tourism conditions were not properly documented. The study investigated the tourism condition in Lagos, Nigeria. The study observed that tourism condition in the nation is presently not provided for all citizenry. The need of the majority was not considered while some of the existing few are in deplorable condition. Previous literatures reviewed shows that almost 75 percent of tourist centres are for children meaning they lack creative environment. This paper also attempts to discuss in detail the little infrastructural evidences that exists in tourism. Fifteen centres were selected and eight were investigated in this study. The study discuss the consistency of findings across Lagos State, using different methodological approaches with consideration to the major key compares the magnitudes of developing natural environment. The study adopted questionnaire as the tool for the investigation, the tool was randomly administered after which the outcomes were analysed with the use of Statistical Package for the Social Sciences, SPSS version 16. Furthermore, aside that personal observation data was also recorded. The study identifies the emerging policy, business opportunity strategy and activities for good governance and better environment. Service provider should be willing to create the inspiration garden in other to have a greater benefits and more patronage. Since most of the centres investigated are static in nature, the study suggested that in the future, research should focus on the analysis of respondent welfare in a dynamic sense.

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.
