Mobile Dwelling Unit Developed by a Group of Mechanical Engineering Design Students

The increasing number of homeless people is one of the most burning problems of nowadays world. Society has to find the way to fight against it and provide help to those people that have no place to stay. For short-term interventions, the application of the mobile dwelling units seems to be the only possible solution. However, existing mobile dwelling units are rather limited to specific areas of application. A group of students faced this problem and decided to develop an alternative, more universal mobile dwelling unit that will fulfil a wide range of different technical and social requirements at a reasonable price. The paper describes a systematic approach to development of the mobile dwelling unit, which was performed as a part of the education process at the Faculty of Mechanical Engineering, University of Maribor. The project presented is interdisciplinary. In addition to the educational aspect that is emphasized in this paper, technical, economic and social aspects of the project have also a very important role. From educational point of view, the project was concluded successfully. Moreover, we believe our proposal for a mobile dwelling unit is both novel and suitable for general application. This revised version was published online in July 2006 with corrections to the Cover Date.     

Growth Volatility and Technical Progress: A Simple Rent-seeking Model

Recent empirical evidence demonstrates that a higher level of technical progress is associated with a lower level of growth volatility and higher expected economic growth. This paper builds a simple growth model which combines the insights of Angeletos and Kollintzas (2000) and Tse (2000; 2001; 2002) with endogenous productivity growth and rent-seeking behavior to account for these stylized facts. Our model complements the literature that focuses on the heterogeneity of different agents.     

南京市人口空间变动分析

在1990年到2000年的两次全国人口普查期间,我国的一些大城市已经出现了明显的郊区化现象,某些城市的中心区人口明显减少而近郊区人口迅速增加.与此相比,南京市主城区的人口规模尚未整体下降,但从微观层面来看,中心区的一些街道的人口已经开始减少,而人口增长最快的街区也主要集中在距离中心点5-10 km的近郊地区.     

Does the look matter? The impact of casino servicescape on gaming customer satisfaction,intention to revisit,and desire to stay

Despite huge investment made by casinos on their physical structures, little has been know if physical environment actually affects psychological responses of gaming customers. This paper explores how dimensions of servicescape influence customer satisfaction and behavioral intentions in the casino environment. Using Bitner's model of physical surroundings, we hypothesized how ambience, navigation, seating comfort, interior decor, and cleanliness affected cognitive and affective satisfaction of gaming customers. We further proposed that gaming customer satisfaction would affect their desire to stay and intention to revisit. Data from 513 gaming customers of Macau offered support to most of our hypotheses. Implications for research and managerial practices were also discussed.     

Macroeconomic sources of foreign exchange risk in new EU members

We address the issue of foreign exchange risk and its macroeconomic determinants in several new EU members. We derive the observable macroeconomic factors—consumption and inflation—using the stochastic discount factor (SDF) approach. The joint distribution of excess returns in the foreign exchange market and the factors are modeled using a multivariate GARCH-in-mean specification. Our findings show that both real and nominal factors play important roles in explaining the variability of the foreign exchange risk premium. Both types of factors should be included in monetary general equilibrium models employed to study excess returns. To contribute to the further stability of domestic currencies, the new EU members should strive to implement stabilization policies aimed at achieving nominal as well as real convergence with the core EU members.     

Web-hosting market development status and its value as an indicator of a country's e-readiness

A country's e-readiness is essentially a measure of its business environment, a collection of factors that indicate how amenable a market is to Internet-based opportunities. An e-readiness assessment is based on several quantitative criteria, and among them the ICT market development indicators are considered as the most influential. Studies in the past have shown that the well-known indicators used for assessing the level of ICT market development in countries with emerging economy are not directly applicable. This paper provides another insight into the level of ICT market development in an emerging economy by analysing the adoption of web-hosting services in the country's business sector. The potential of such assessment to be as an indicator of the level of ICT development in a country is analysed. The underlying study of the web-hosting development was carried out as part of the European project WEBHOSTS. The approach applied and the findings were intended to be used as a decision support in locating and managing some of the risks in e-business development and potential investment by new entrants in a region that is accessing the developed part of Europe.     

Comparison of Benchmarking Methods with and without a Survey Error Model

For a target socio-economic variable, two sources of data with different precisions and collecting frequencies may be available. Typically, the less frequent data (e.g., annual report or census) are more reliable and are considered as benchmarks. The process of using them to adjust the more frequent and less reliable data (e.g., repeated monthly surveys) is called benchmarking.
In this paper, we show the relationship among three types of benchmarking methods in the literature, namely the Denton (original and modified), the regression, and the signal-extraction methods. A new method called "quasi-linear regression" is proposed under the multiplicative assumption. The numerical Denton method is currently widely used. The aim of this paper is to promote the other two methods which are statistically model-based; the model for the survey error is assumed to be known. Assuming the survey-error series follows an autoregressive model of order 1, by simulation, we investigate the impact of misspecification of the model on the benchmarking prediction according to the criterion of minimizing the root-mean-squared error of prediction. It is concluded that both statistical methods have great advantages over the Denton method and they are robust to misspecification of the survey-error model. The problem of how to obtain a survey-error model is also mentioned.     

An importance–performance analysis of sustainability factors for long-term strategy planning in Slovenian hotels

This paper explores the potential role of economic, environmental and social reporting in long-term strategy planning in the hospitality industry. The context of study is Slovenia. Following the development of a set of “sustainability” indicators, hospitality managers were asked to rate the importance of each indicator to sustainable operations and the performance of their firms in implementing management actions. Seven hotel performance factors were established across the triple bottom line. Using importance–performance analysis (IPA), key issues are identified as requiring the attention of stakeholders to support the sustainable development of Slovenia's hospitality industry. For managers, the 10 most important indicators include those related to economic performance, customer relationship and cost saving environmental activities: performance here, and in marketing, was perceived as poor. In contrast, actions taken to increase environmental awareness, and improve relationships with employees are seen by managers as less important, and even as possible overkills. Community relationships are seen as of low importance and where the industry performs relatively poorly. A major recommendation is that Slovenian hotel managers should focus on improving their economic performance: neglecting this could threaten hotels’ long-term survival. IPA analysis is shown as applicable to strategy making for sustainable development in hospitality industry contexts worldwide.     

Increasing Wealth and Increasing Instability: The Role of Collateral

In development economics, growth in credit is generally associated with faster long-run growth as financial intermediation improves the efficiency of channeling capital to productive investment. Yet, among developing countries high growth in credit almost always guarantees the outbreak of a financial crisis. The authors attempt to reconcile the two seemingly contradictory facts with an endogenous growth model in which entry to international borrowing entails some significant fixed cost. The poorest countries are excluded from international borrowing because of the fixed cost. The higher-income developing countries will find it optimal to sink the fixed cost to borrow internationally, growing faster as a result, but also become prone to fluctuations arising from shocks to the international financial market.
