Segregation in Minds

In this paper, I explore socio-spatial segregation from a particular perspective, which may probably be considered a novelty in the investigation of spatial social patterns, as it focuses on questions such as: What kind of distinction occurs between socio-spatial patterns designated by statistical data and the cognitive representations of those patterns in people's minds? and What explains these diff erences, and what kind of impact can they generate?

Emberierőforrás-menedzsment gyakorlatokkal kapcsolatos kutatások a lean termelés irodalmában (Researches on human resource management practices of lean production literature)

A lean termelési rendszer szociotechnikai megközelítése szerint a lean technikai elemei (technikai alrendszer) a kimagasló teljesítményt nyújtó munkaerő-szervezési rendszer (HPWS) gyakorlataival (szocio alrendszer) kapcsolódnak össze. A tanulmány ezt a megközelítést MacDuffie (1995) szervezetilogika-koncepciója alapján mutatja be. A lean termelési rendszer munkaerő-szervezési rendszerével kapcsolatosan négy témakört tekint át: (1) a lean termelési rendszer munkaerő-szervezési rendszerekre gyakorolt hatását, (2) a HPWSgyakorlatok használatát és (3) teljesítményhatását, végül a (4) munkásokra gyakorolt hatásokat. A feldolgozott koncepcionális és empirikus munkákban valamennyi pontban számos ellentmondás fedezhető fel. _____ According to the socio-technical view of lean production lean system is built on both technical and human resource practices (subsystems). The concept of organizational logic developed by MacDuffie (1995) describes how lean techniques and high performance working systems practices mutually suppose each other in lean environment. This study reviews four fields of human issues in relation to lean production: (1) the impact of lean system on work organization; (2) the use HPWS practices and (3) their impact on operational performance indicators in lean producers; (4) the impact of lean production on workers. The review of empirical and conceptual studies points out that there are many contradictions regarding the above points.

Is the Netherlands sustainable as a global-scale inner-city? Intenscoping spatial sustainability

Is the Netherlands sustainable or not? The answer inherently involves addressing the issues of system boundaries, statistical units and a vision of sustainability. As an analytical answer we offer the Intenscope (IS), a two-dimensional graphical tool based on dimensionless percentages of triple rate ratios which overcomes several limitations of sustainability analyses. First, it is not sensitive to the size of statistical units so an area with twice the amount of resources of another, with double the population (and double the total consumption) would have the same triple ratio of population:biocapacity:consumption. Second, the IS is sensitive to anomalies which may originate either from the use of arbitrary statistical units (e.g. the boundaries of a city) or those which may indicate truly unsustainable practices. To judge spatial sustainability we use ecological footprint data from which we construct a plausible country plot based on the IS. Despite the relative nature of IS-analyses, the employed consumption:biocapacity ratio inherently refers to the absolute limit of sustainability: we cannot continually use more resources on a global scale than nature provides us with. The analysis introduces some associations of human preferences and attributions of settlement types which may help to elaborate sustainability policies based on voluntary action.
