Urban Utopias and Suburban Slums: A Demographic Analysis of Suburban Poverty and Reurbanization in American Metropolitan Statistical Areas

This study examines 2000 and 2010 Census data to determine the resettlement patterns of urban and suburban residents in 23 American metropolitan statistical areas (MSAs). Previous research discusses the development of an affluent suburbia, leaving postindustrial cities in decline. However, recent literature suggests the reurbanization of postindustrial cities by the creative class, a Return to the City movement fueled by middle class entrepreneurs, artists, and technocrats. Alongside reurbanization are increases in poverty, and racial and ethnic enclaves in suburbia. The literature shows these trends as two separate, independent processes. This study investigates the relationship between these processes within MSAs. Consistent with existing literature, this study finds that from 2000 to 2010, there are increases in poverty and racial and ethnic diversity in the suburbs, and increases in middle and upper class white populations within central cities. This study reveals quantitative data concerning the future of American urban and suburban demography

WHY PHUBBING IS TOXIC FOR YOUR RELATIONSHIP: UNDERSTANDING THE ROLE OF SMARTPHONE JEALOUSY AMONG “GENERATION Y” USERS

Coined as “phubbing”, excessive use of smartphones in the romantic context has been shown to rep-resent a barrier to meaningful communication, causing conflict, lowering relationship satisfaction, and undermining individual well-being. While these findings project a dire picture of the future of romance, the mechanisms behind the detrimental influence of partner phubbing on relationship-relevant markers are still little understood. Considering prior evidence that partner phubbing leads to the loss of exclusive attention towards the other party, we argue that these are rather the feelings of jealousy partner phubbing is triggering that are responsible for the negative relational outcomes. Based on the analysis of qualitative and quantitative responses from “generation Y” users, we find that partner phubbing is associated with heightened feelings of jealousy, which is inversely related to couple’s relational cohesion. Moreover, jealousy plays a mediating role in the relationship between partner’s smartphone use and relational cohesion, acting as a mechanism behind this undesirable link. Challenging the frequently promoted euphoria with regard to permanent “connectedness”, our study contributes to a growing body of IS research that addresses dark sides of information technolo-gy use and provides corresponding implications for IS practitioners

Knowledge Antecedents of Absorptive Capacity: A Meta-Analysis

A firm’s absorptive capacity -its ability to recognize, assimilate, and exploit knowledge- has been viewed as one of the most investigated constructs in organizational research over the last two decades. Knowledge as a focal antecedent of absorptive capacity has been studied extensively. However, the results represent fundamentally different aspects of knowledge which has led to a fragmentation of the literature. Thus, it remains unclear which dimensions of knowledge are relevant for the development of absorptive capacity. By applying meta-analytical methods in 156 samples representing 284,144 firms, we examine the links between different knowledge antecedents and absorptive capacity, considering knowledge forms (knowledge assets and routines and processes), knowledge characteristics (quantity and quality) as well as knowledge contexts (firm internal and inter-firm). While our findings display significant positive impact of different knowledge antecedents on absorptive capacity, these relationships vary in strength. Our findings confirm the relevance of knowledge routines and processes and firm internal quality of knowledge for the development of absorptive capacity. Interestingly, the quantity of knowledge a firm possesses appears to be less important. Our results furthermore suggest knowledge antecedents to be more relevant in the firm internal context. This challenges the general assumption in the absorptive capacity literature, which emphasizes the importance of inter-firm cooperation for the development of absorptive capacity. In our post-hoc test, we extend our conceptual model and assess absorptive capacity’s mediating role between knowledge antecedents and innovation. We provide a fine-grained, integrated framework on absorptive capacity’s knowledge antecedents, highlighting their differential importance for absorptive capacity

Improving effectiveness of alien plant clearing on Reunion Island through partnership

International audienceBiological invasions threaten biodiversity worldwide, especially on tropical islands such as Reunion Island. Here we present the results of a collaborative effort to map biodiversity priorities and to prioritise alien plant clearing. We first combined all existing data on habitats, threatened and endemic species and the distribution of alien plant species. Using expert-knowledge where necessary, we provide the first map of invasion level for the whole island. We developed a decision-making process using Zonation, a conservation-planning tool, to identify biodiversity conservation priorities. Conservation priority areas were selected to maximise biodiversity levels in areas lightly invaded. We then included criteria to identify priority areas for alien plant clearing based on clearing costs, accessibility and history of previous clearing programmes. Almost 40% of the remaining natural habitats on Reunion Island are moderately to heavily invaded. We identify 58,500 ha as conservation priority areas of which 30%are considered to be not invaded at all. We discuss how this will impact future alien plant clearing programmes and propose the basis for an integrated clearing and restoration plan for Reunion Island
