Using Data

Vigil’s multiple marginality (MM) model of gang formation has resulted in hypotheses about why minority youth join gangs, and how these processes play out at multiple levels of analysis and across contexts. However, with a few exceptions, this framework has rarely been tested quantitatively, and especially in countries outside of North America. The current study assesses the MM model using data from the Second International Self-Report Delinquency Study and aggregate country-level data. Results from multilevel analyses reveal some support for the framework, in that at least one measure of each component of the MM model was found to be a significant predictor of gang membership. Controlling for individual and country variables, measures of street socialization exhibited the strongest effects on gang involvement. Yet not all proposed factors were significant predictors across all models. Longitudinal data are necessary to fully support the dynamics of the MM model.

AbstractScholars have explained working-class speakers’ continued use of stigmatised vernaculars as a response to their relative powerlessness in relation to the standard language market. Research has shown how, in the face of this powerlessness, working-class communities turn to group solidarity, and use of the vernacular is seen as part of this more general orientation. As a result, two competing social values—status and solidarity—have featured prominently in discussions around language and class. I expand these discussions using data from a linguistic ethnographic study of children's language in Teesside, England. I argue that meanings related to status and solidarity operate at multiple levels and cannot be taken for granted, and demonstrate that vernacular forms thatlackstatus within the dominant sociolinguistic economy may be used toassertstatus within local interactional use. I further advance discussion of the ways local vernaculars might be intimately linked to classed subjectivities.

Using Data

The distribution pattern, frequency and density (ind./1000 m) of different mesozooplankton species from the South Georgia Islands, South Orkney Islands and the Weddell-Scotia Confluence were analyzed using data obtained in 1994. The maximum densities of the species found were: Eukrohnia hamata (5330), Sagitta gazellae (1052), Clione limacina antarctica (450), Spongiobranchaea australis (375), Clio sulcata (100), Limacina helicina (4076 x 10³), Limacina retroversa (71 x 10(4)), Pelagobia longicirrata (29170), Rhynchonereella bongraini (117), Tomopteris carpenterii (26), Tomopteris planktonis (498), Tomopteris septentrionales (498) and Salpa thompsoni (189). Species density and frequency decreased from South Georgia to the South Orkney Islands, recording intermediate values at the Weddell-Scotia Confluence. Species density in the South Orkney area seemed to be limited by variations in temperature and salinity. The southern area around South Georgia showed the highest density of species, probably due to the influence of the Southern Front of the Antarctic Circumpolar Current. The presence of species characteristic of sub-Antarctic waters such as L. retroversa in the Confluence area could be related to the southward movements of eddies that originate in the Polar Front.

This chapter examines the theoretico-methodological practice of “exampling.” After all, in concept-driven sociology, examples are the data, assuming the form of specific empirical illustrations of generic patterns. By using concrete “cases” yet disregarding their singularity, concept-driven researchers can empirically instantiate those abstract, initially difficult-to-grasp patterns. As this chapter demonstrates, a generic sociology calls for multicontextual data. In order to identify generic, transcontextual social patterns, one needs to encounter them in multiple social contexts, and the wider the range of contexts in which one collects one’s data, the more generalizable the patterns they reveal. Such contextual diversity is manifested multi-culturally (drawing on examples from diverse cultural contexts), multihistorically (using data from a wide range of historical periods), multisituationally (drawing on examples from diverse social “domains”), as well as at multiple levels of social aggregation (effectively disregarding scale).

Worldwide, educational institution has channeled big investments towards building information systems. This paperdeals with data marts ideas, which is a database, or collection of databases, designed to help managers make strategic decisionsabout their business. In this paper we suggest a project named IC-DM for the educational institution which has access to twodifferent data marts that user will need to decide which is the most appropriate for the project that they are working on. Datafrom multiple sources, and multiple levels was linked, or merged into a data mart.
