Multiple Job Holding,Skill Diversification,and Mobility

In this article, we investigate the interrelated dynamics of dual jobholding, human capital, occupational choice, and mobility, using a panel sample (1991–2005) of UK employees from the British Household Panel Survey. The evidence suggests that individuals may be using multiple jobholding as a conduit for obtaining new skills and expertise and as a stepping‐stone to new careers, also involving self‐employment. Individuals doing a different secondary job than their primary occupation are more likely to switch to a new primary job in the next year, and a job that is different than their current primary employment. The results show that there are human capital spillover effects between primary and secondary employment.     

Domestic firms competing with multinational enterprises: The relevance of resource-accessing alliance formations

The literature includes several papers that compare multinational enterprises (MNEs) to local firms along several dimensions such as financial strength or production capacity. Nevertheless, the focus on how latter firms compete against the former is often missing in the literature; local firms are typically seen as inferior in terms of resources and thus, unable to compete against MNEs. This paper aims at revisiting this competitive ‘battle’. Through a case-based design in a ‘multinational’ domestic market that seems to favour MNEs, we explore how local firms respond to MNEs’ purported superiority. Findings indicate that local firms respond through alliance formations that enable them to access fitting resources and counter ownership advantages of MNEs. Therefore, resource-accessing strategies spearheaded by local firms suggest that ownership advantages should not be inherently translated into competitive advantages for the MNEs. Implications for international business are discussed and avenues for further research are suggested.     

A Calibrated Group Decision Process

In practice most organisational decisions are made by groups that bring into the problem multiple perspectives, both complementary and contradictory. When having a group of decision makers, usually individuals’ preferences are either led to consensus or are aggregated with the use of some function like the median, the arithmetic or geometric mean. We focus in the second case, where individual’s preferences need to be aggregated. Our approach is based on the fact that when two decision makers are asked to give their preference between a pair of criteria using a specific scale, it is possible that they will give slightly different answers, even when they actually have the same opinion. This difference will not affect the case of a single decision maker, as it will be consistent throughout the whole process. However, it can affect a group decision when the values will be used as an input for the aggregation function. A novel approach is presented that enhances group decision making through a group calibration process. The proposed process adjusts individuals’ preferences based on their answers on a set of standardized questions prior to the aggregation phase. The method focuses The whole concept is applied to the group analytical network process method and it is illustrated through a telecommunications project case. The decision under examination concerns the selection of the right place for deploying a new telecom service of a multinational-based telecommunications company where a group of geographically dispersed decision makers form an ad-hoc virtual team in order to select the location for a new technical support centre.     

Hosts, guests and politics: Coastal Resorts Morphological Change

Resort morphology goes through a predictable sequence of stages: from pre-tourism low through high-density development to an urbanized state. Three elements are considered essential in such coastal resorts change: hosts, guests, and politics. Using historical data from the mass-developed Greek island of Crete, ten principal characteristics are identified as determinants of the morphological change of coastal resorts. A temporal model of unplanned change is also proposed. Although the study was constrained by limited data availability, the proposed model is deemed able to represent the morphological change of Cretan mass-developed coastal resorts.     

Containership routing with time deadlines and simultaneous deliveries and pick-ups

In this paper we seek to determine optimal routes for a containership fleet performing pick-ups and deliveries between a hub and several spoke ports. A capacitated vehicle routing problem with pick-ups, deliveries and time deadlines is formulated and solved using a hybrid genetic algorithm for establishing routes for a dedicated containership fleet. Results on the performance of the algorithm and the feasibility of the approach show that a relatively small fleet of containerships could provide efficient services within deadlines. Moreover, through sensitivity analysis we discuss performance robustness and consistency of the developed algorithm under a variety of problem settings and parameters values.     

Tourism in Crete: A Form of Modernisation

Tourism in Crete is an irreversible phenomenon that has resulted in a process of change under the form of modernisation. This modernisation has both positive and negative consequences. Specifically, tourism has been transformed into a primary source of income and employment generation for the island and has improved the quality of life for the locals. However, tourism development was directed to the increase of demand through the increase of the numbers of beds, as well as the concentration of tourist arrivals in space and time, rather than the balanced development of the tourism industry. In effect, various social and environmental strains have resulted, such as environmental degradation, cultural pollution, commercialisation of human relations and negative demonstration effects. It is the aim of this paper to review past studies, having examined various aspects of tourism in Crete in order to investigate the costs and benefits associated with the modernisation of the island through tourism expansion and to provide recommendations for future development.     

Job displacement and the transitions to re-employment and early retirement for non-employed older workers

Despite the relatively higher frequency of job displacement among older workers in Europe, little is known about its effect on the work-retirement decision. Employing individual data from the European Community Household Panel for a number of countries with differences in their institutional environments, the effect of job displacement for non-employed workers is identified separately for the transitions into re-employment and retirement. The findings suggest that in countries with relatively more generous unemployment insurance provisions for the older unemployed, which offer a pathway to early retirement, older displaced workers exhibit lower re-employment and higher retirement rates compared to the non-displaced. These results are robust to dynamic selection due to unobserved heterogeneity and to the endogeneity of displacement.
