Mobile games are a prime example of a successful mobile application and demonstrate the increasing range of platforms for the media and entertainment industries. Against this convergent background, this paper introduces the basic features of the mobile gaming market and its industrial ecosystem together with its main actors and activities. The focus of the paper lies in the challenges ahead for the evolution of mobile applications into a potentially dominant game platform and the possible disruptions along this road. The deep personal relationships between users and their mobile devices are considered to further explore the link between mobile games, players’ strategies and pending techno-economic developments. The paper concludes with a brief discussion of some policy options to assist with the development of this domain. 相似文献

The prerequisite for a sustainable and equitable use of common resources (the so-called Commons) must be the proper evaluation of their role within the complex network of relationships that ensure ecosystems functioning, resilience, and evolutionary dynamics. It is crucial to ascertain to what extent the common wealth is used for the common benefit. Money-based schemes for valuing the Commons, such as the so-called “willingness-to-pay”, provide a user-side evaluation perspective based on the idea that value only stems from utilization by humans. As a complement to such a point of view, we present and discuss in this paper a donor-side evaluation method (Emergy Synthesis) based on the idea that a proper measure of value can be achieved by also accounting for the work done by the biosphere in generating services and resources. It should not be disregarded that such resources and services also provide support to other species in the web of life. Emergy, a scientific measure of such environmental support, is suggested as a tool capable to assess quantity and quality of shared resources, thus providing a basis for their environmentally sound management. 相似文献

Port workers services have been usually heavily regulated and reserved exclusively for a special kind of workers, dockworkers,
which seems to have been the cause of serious inefficiencies worldwide. During the eighties, law reforms have been introduced
to solve this problem. In this paper we analyze and decompose efficiency in cargo handling operations in 19 Spanish ports
from 1990 to 1998. The method chosen is that of the parametric estimation of both allocative and technical inefficiency using
panel data and a quadratic cost function. Results show that although inefficiency has decreased overall, there has been over
utilization of labor regarding capital, and technical inefficiency. This supports the need of further consideration of other
aspects including competition.

The generalized expected utility model is fitted to U.S. farm data to estimate farm operator's time preferences and risk attitudes. The estimated farmer's utility parameters are quite 'reasonable' and exhibit high accuracy. The forward-looking expected utility model is soundly rejected in favor of the generalized expected utility paradigm. Importantly, the generalized expected utility model is also found to fit the data better than the myopic model typically used to study agricultural production under risk. Finally, U.S. farmers' relative aversion to risk appears to have diminished significantly over time. 相似文献

The geographical allocation of Spanish aid has been little studied, despite its unusual concentration on middle-income countries. This paper develops a theoretical model in which aid allocation depends on a combination of recipient needs, donor interests and performance criteria, and estimates it econometrically for Spain. The results show that the allocation of Spanish aid has been influenced both by Spain's own foreign policy interests and by recipient needs for poverty reduction and development (although not by the quality of recipient governance or recipient absorptive capacity). Former Spanish colonies received a disproportionate share of Spain's aid (as is true mutatis mutandis for other European countries), but aid is allocated among them with greater regard to recipient need than is Spain's aid to other developing countries. 相似文献

The objective of this paper is to identify the determinants of the reactions of farm households to the decoupling of the Common Agricultural Policy (CAP) focusing, in particular, on changes in on-farm investment behaviour. The paper analyses a sample of 248 farm-households in 8 EU countries, using a non-parametric approach based on classification tree algorithms. The factors emerging as determinants of an increase in on-farm investment as a reaction to decoupling are: specialisation, existence of a successor, the farmer's age, labour management, SFP per hectare, location and expectations. When used, country variables, tend to substitute some of the factors listed above and become the main predictors, followed by labour endowment, specialisation and expectations. While the study confirms the relevance of the main determinants available from the literature, it also emphasises the articulation (non-linearities) of the effects of farm head age, labour management and SFP per hectare on the reactions to decoupling. This hints at the need for further research on the way such factors combine in determining farm-household reactions to a changing market and policy context, and support the usefulness of non-parametric statistics tools for such types of analysis. 相似文献

In this article I describe a methodology for the mapping of Operational Risk with the objective of identifying the risks inherent in the different steps of a business process, selecting a set of variables providing an estimate for the likelihood and the severity of operational risk (Key Risk Indicators – KRIs) and designing the most appropriate control activities. I then present two examples of how the methodology described can be applied to map risks and of how a set of relevant KRIs can be identified in the front office of a trading business and in the back office of a lending business. Finally, I discuss how the information conveyed by the KRIs can be organised and summarised in order to provide a comprehensive look at the risk profile of the various business lines. The structured presentation of KRIs covering the business processes of a bank is what we call an Operational Risk Scorecard. 相似文献

Actually, the country's development aims to achieve higher levels of productivity, so it had to adapt to international standards. This has served to ease the hiring of both operational and managerial controls, giving emphasis on training and allowing the pairing boss-worker to take the productivity like benchmark. The labor reform allows companies to make changes with their workers; such changes must be reflected in lower costs for businesses, by labor input and increased competitiveness, however, two years ago this guideline was implanted and society asks if the results are congruent, because Mexican society is undergoing economics problems issue as well as a deficit in generating jobs. Therefore, analyzing whether modifications made to the federal labor law (FLL) are designed to optimize safety of workers and enterprises in which they work is the subject of this research. The corresponding analysis was performed using the deductive method. 相似文献

Falling real incomes, rising utility prices and the historically poor thermal quality of the housing stock are some of the main factors that have driven the rise of systemic injustices surrounding energy poverty in the post-communist states of Eastern and Central Europe (ECE). We undertake a socio-spatial and temporal assessment of energy poverty in Hungary, the Czech Republic and Poland, using Household Budget Survey micro-data and the consolidated national results of the EU Survey of Income and Living Conditions. Our results indicate that increases in domestic energy prices and expenditures during the last decade have not been offset by purchasing power gains or energy efficiency improvements, resulting in sustained and growing levels of energy poverty. Capital city regions have fared better than rural areas even if traditional macroeconomic performance indicators do not easily match domestic energy deprivation metrics. We thus question policy approaches that favour income-based solutions and fail to recognise housing- and demography-related vulnerabilities. 相似文献
