Local social services in disaster management: Is there a Nordic model?
2017
Abstract The Nordic states have extensive welfare systems in which the local social services are an important component. Despite a growing research on disaster resilience, we lack research examining in systematic way whether and how local social services in the Nordic countries contribute to resilience. Aiming to fill this gap, this article asks whether we can identify a common Nordic model of the role of local social services in disasters, or whether the countries have taken different paths. We use policy documents and legislation to examine the extent to which roles for local social services are embedded in the disaster management systems of the five Nordic countries. We analyze the insti…
Measuring Globalization of International Trade: Theory and Evidence
2009
Measuring globalization requires a Standard of Perfect International Integration as a benchmark that a single world space would reach under conditions of geographic neutrality in international trade. We define this standard and present indicators for openness, connectedness and integration, for each specific economy, and for the world economy. We apply our indicators to data on trade flows for 59 countries for the 1967-2004 period. Results show that trade integration is higher than what traditional openness indicators suggest. Several economies find high levels of integration, but the low degree of openness in some large economies jeopardizes the progress of globalization. © 2008 Elsevier L…
Life cycle assessment of low temperature asphalt mixtures for road pavement surfaces: A comparative analysis
2018
The increasing fuel consumption demand, the accelerated pressure imposed by the depletion of 5 scarce raw materials and the urgent environmental protection requirements are forcing the change of 6 pavement industry and academia community’s research endeavors towards the development of low 7 emissions road paving technologies able to significantly reduce mixing and compaction temperature as 8 well as the consumption of virgin raw materials. One set of relatively recent technologies in the field of 9 pavement materials that aims at addressing those concerns are the warm mix asphalt (WMA). In fact, 10 they have the potential to allow the reduction of energy consumption and airborne emissions d…
Leadership Manipulation and Ethics in Storytelling
2012
This article focuses on exerting influence in leadership, namely manipulation in storytelling. Manipulation is usually considered an unethical approach to leadership. We will argue that manipulation is a more complex phenomenon than just an unethical way of acting in leadership. We will demonstrate through an empirical qualitative study that there are various types of manipulation through storytelling. This article makes a contribution to the literature on manipulation through leadership storytelling, offering a more systematic empirical analysis and a more nuanced view of the topic than previously existed by outlining how managers engage in manipulative storytelling and what kind of ethics…
An upper echelons perspective on information technology business value
2017
This paper argues that information technology (IT) outcomes are more valuable to companies when their top management team (TMT) moves from flirting with IT to marriage. Previous research has demonstrated an association between top management support (TMS) and IT value. We extend the concept of TMS with the imbrication metaphor to define the construct of TMT-IT imbrication, which allows us to account for a tighter and continuous entwining of the TMT and IT to create IT value. Our definition of the TMT-IT imbrication construct embraces four dimensions: involvement, participation, attention, and use. In addition, with the support of upper echelons (UE) theory, we explore certain managerial tra…
Measuring the presence of organized crime across Italian provinces: a sensitivity analysis
2020
AbstractThe existing literature identifies different indicators to construct organized crime indices and places equal importance to different concepts of organized crime. This paper examines the sensitivity of organized crime across Italian provinces when different set of indicators and weights are used to combine crime indicators. Our findings suggest that there is a remarkable variation in the distribution of organized crime across Italian provinces based on the choice of indicators and the importance given to different crime indicators. It is also found that the relationship of organized crime with socioeconomic and political factors varies depending on the normative choices made in the …
Job Mobility and Sorting: Theory and Evidence
2019
Abstract Motivated by the canonical (random) on-the-job search model, I measure a person’s ability to sort into higher ranked jobs by the risk ratio of job-to-job transitions to transitions into unemployment. I show that this measure possesses various desirable features. Making use of the Survey of Income and Program Participation (SIPP), I study the relation between human capital and the risk ratio of job-to-job transitions to transitions into unemployment. Formal education tends to be positively associated with this risk ratio. General experience and occupational tenure have a pronounced negative correlation with both job-to-job transitions and transitions into unemployment, leaving the r…
Temporary contracts, employment protection and skill: A simple model
2008
Abstract We construct a theoretical labor market that incorporates skill differences across workers to identify under which conditions temporary contracts are a way to access to permanency. Firing costs and unemployment benefits increase the threshold productivity above which workers access to permanency.
Automatic Segmentation and Enhancement of Pavement Cracks Based on 3D Pavement Images
2019
Pavement cracking is a significant symptom of pavement deterioration and deficiency. Conventional manual inspections of road condition are gradually replaced by novel automated inspection systems. As a result, a great amount of pavement surface information is digitized by these systems with a high resolution. With pavement surface data, pavement cracks can be detected using crack detection algorithms. In this paper, a fully automated algorithm for segmenting and enhancing pavement crack is proposed, which consists of four major procedures. First, a preprocessing procedure is employed to remove spurious noise and rectify the original 3D pavement data. Second, crack saliency maps are segmente…
Drivers of social commerce usage: a multi-group analysis comparing Facebook and Instagram
2020
Social media are increasingly used as platforms to not only socialise but also to shop for products and services. Social commerce is the new trend in e-commerce that leverages the enhanced consumer-to-consumer interactions to support shopping processes. Based on the concept of social commerce constructs suggested by Nick Hajli, this article investigates the role of social commerce constructs, emotional and informative support, and trust as drivers of social commerce intention. We apply multi-group analysis to validate the drivers of social commerce for two of the most relevant social media platforms: Facebook and Instagram. Based on a sample of 800 social commerce users, our findings reveal…
