Kimutatható-e az e-kereskedelem hatása a vállalati teljesítményre a recesszióval küzdő magyar kiskereskedelmi piacon? A hagyományos bolti értékesítés vagy on-line kereskedelem vezet hazánkban jobb pénzügyi teljesítményhez? Ezekre a kérdésekre a magyar IKT (infokommunikációs technológiai) kiskereskedők 187 elemű mintáján igyekeznek a szerzők választ keresni, az adatgyűjtést újszerű módon részben automatizált webpókokra bízva, következtetéseiket pedig elsősorban klaszterelemzési technikákra építve. Megállapítják, hogy bár a legjobb bolti kereskedők többnyire valamivel nagyobb és stabilabb profitrátákkal jellemezhetők a válság éveiben is, a piac megtartása és növelése terén már egyértelműen az e-kereskedők jeleskedtek. Eredményeik szerint az e-kereskedelem hozzásegítheti a kiskereskedőket a munkaerő-hatékonyság növeléséhez is, ám ha gyors rendelkezésre állással vagy alacsony árakkal csábítják vevőiket, akkor a profittöbblet egy részét felőrölheti a magasabb készlettartási igény vagy az árverseny. _____ The study examines whether e-commerce has a significant impact on corporate performance on the Hungarian retail market struggling with the effects of economic downturn. Is it brick-and-mortal retail or e-commerce that leads to a better financial performance? Using the innovative data gathering tools of automotive web crawlers the authors seek answers to these questions on a sample of 187 Hungarian ICT retailers. Based on cluster analysis they conclude that while the best traditional retailers have somewhat higher and more stable profitability ratios even during the years of recession, e-tailers are more successful in retaining and increasing their market share. E-commerce is also associated with higher human resource productivity, but the possible profit surplus originating from this advantage could be jeopardized in the long run as new electronic traders typically attract their customers by shorter service time or lower prices.

Items of various types arrive at a bin-packing facility according to random processes and are to be combined with other readily available items of different types and packed into bins using one of a number of possible packings. One might think of a manufacturing context in which randomly arriving subassemblies are to be combined with subassemblies from an existing inventory to assemble a variety of finished products. Packing must be done on-line; that is, as each item arrives, it must be allocated to a bin whose configuration of packing is fixed. Moreover, it is required that the packing be managed in such a way that the readily available items are consumed at predescribed rates, corresponding perhaps to optimal rates for manufacturing these items. At any moment, some number of bins will be partially full. In practice, it is important that the packing be managed so that the expected number of partially full bins remains uniformly bounded in time. We present a necessary and sufficient condition for this goal to be realized and describe an algorithm to achieve it.

The discovery of oil in West Asia has contributed to its integration into the international capitalist system. The mono-commodity, oil, has brought tremendous wealth to West Asia. But a rising population and an ever growing demonstration effect, has caused imports to grow exorbitantly, with oil prices expected to fall, depicted explicitly by recent oil price drop, also over time as interest in climate change increases after RIO-20, and more options of renewable energy sources coming on line like Gas, Solar Energy, wind power and nuclear energy etc. the rentier mode of development followed by west Asian economies is clearly unsustainable. Further the oil producing nations are so over-specialized that they do not possess the necessary flexibility to shift their resources from one sector to another, or to develop substitution if and when the need arises. Moreover, the ability of oil producing countries to respond to deliberate or accidental economic measures taken abroad is limited. This paper theoretically analyses the standing of the West Asian mono product economies, their specific traits, benefits and disbenefit of current condition and looks into the case for diversification of West Asian Region. As diversification is a sine qua non in long Run for the sustainability of the West Asian economies.

Social capital is formed from individual abilities through the social investment that contributes to value creation where individuals feel a sense of membership and commitment through their social interactions and relationships. This study aims to explore the application of social capital to women's organizations. It further explores the net social value of women's organizations and the women members to determine social capital's role as a means for value creation. At these ends, the mixed method was employed by combining qualitative and quantitative data gathering approaches. The study used key informant interviews among 11 women's organizations in Baguio City and Benguet, where a total of 284 women members were interviewed. The result of the talks was subjected to semantic analysis and net present social value analysis. The results reveal that women's organizations reflect the dimensions of social capital and bring a significant contribution to members' lives. The findings imply that women members are duly recognized in their organizations, and each member expects to receive a positive value of the social benefit. Hence, women's organizations are the embodiment of social capital that contributes to women's value creation and empowers their members to maximize their capacities.

Open Position

Companies producing, processing and consuming commodities in the production process often hedge their commodity expositions using derivative strategies based on different, highly correlated underlying commodities. Once the open position in a commodity is hedged using a derivative position with another underlying commodity, the appropriate hedge ratio must be determined in order the hedge relationship be as effective as possible. However, it is questionable whether the hedge ratio determined at the inception of the risk management strategy remains stable over the whole period for which the hedging strategy exists. Usually it is assumed that in the short run, the relationship (say, correlation) between the two commodities remains stable, while in the long run it may vary. We propose a method, based on statistical theory of stability, for on-line detection whether market movements of prices of the commodities involved in the hedge relationship indicate that the hedge ratio may have been subject to a recent change. The change in the hedge ratio decreases the effectiveness of the original hedge relationship and creates a new open position. The method proposed should inform the risk manager that it could be reasonable to adjust the derivative strategy in a way reflecting the market conditions after the change in the hedge ratio.

In February 2009, Tony Fernandez, the founder of AirAsia was not bothered by the company’s mass order of 175 new aircraft for its AirAsia-X long-haul services. He could not resist the concern over the aircraft deferment to Thailand and Indonesia in 2011 because of the relocation of the low-cost carrier terminal in Sepang before AirAsia was forced to move to KLIA2. Such a situation would surely increase its operating costs exponentially. He also knew he was facing an economic downturn and the high competition, particularly for his AirAsia-X business. Major rivals of AirAsia-X in the region were Singapore Tiger Airways, Cebu Pacific Air of the Philippines and a global competitor was EasyJet in Europe had just launched aggressive campaigns and promotions which would affect its long-haul business. He was certain that the company would achieve his dream to spread its wings all over the world. However, he realized that the company’s operating costs and competition with other airliners that joined the club of no-frills airlines based on a national and international level presently had escalated. He knew he had to act now. If you were Tony Fernandez, what would you do in this scenario was a question that needs an answer? This is an issue of strategic choice of divesting or integration as the strategic options are limited in the short as well as long run. The AirAsia case study has the main objective of sharing impact of the covid-19 pandemic devastating impact on the airliners. It is a significant study in terms of impact on economy, tourism and hospitality industry in general and Malaysia in particular.

Tax Cuts

<p>Policies to cut taxes and fees are important means to deal with the economic downturn, which strongly support to the development of the majority of small and medium-sized enterprises (SMEs). The current study has no consistent conclusion of whether SMEs expand their labor demand because of this. This paper builds a structural vector autoregressive (VAR) model to analyze the dynamic effects of tax cuts and fee reduction policies on increasing labor demand for SMEs. The empirical results show that tax cuts and fee reductions are important causes of short-term employment fluctuations, but in the long run, it is difficult for taxation policies to have a direct positive effect on employment. Therefore, this article puts forward the idea that different tax incentives can be formulated for small and medium-sized enterprises in the short term according to their life cycles. In the long run, the focus of macro-control needs to be turned to supply management to achieve the goal of stable employment.</p>

Globally, there is a lack of resources to survey the vast seafloor areas in need of basic mapping data. Consequently, smaller areas must be prioritized to address the most urgent needs. We developed a systematic, quantitative approach and on-line application to gather mapping suggestions from diverse stakeholders. Participants are each provided with 100 virtual coins to place throughout a region of interest to convey their mapping priorities. Inputs are standardized into a spatial framework using a grid and pull-down menus. These enabled participants to convey the types of mapping products that they need, the rationale used to justify their needs, and the locations that they prioritize for mapping. This system was implemented in a proposed National Marine Sanctuary encompassing 2784 km2 of Lake Michigan, Wisconsin. We demonstrate key analyses of the outputs, including coin counts, cell ranking, and multivariate cluster analysis for isolating high priority topics and locations. These techniques partition the priorities among the disciplines of the respondents, their selected justifications, and types of desired map products. The results enable respondents to identify potential collaborations to achieve common goals and more effectively invest limited mapping funds. The approach can be scaled to accommodate larger geographic areas and numbers of participants and is not limited to seafloor mapping.

This paper discusses the use of computing machines in the biological and social sciences, namely the ultilization of computerized behavior analysis systems in the quantification of human behavior. Only systems of which living human organisms are a part are considered. Some specific functional uses of computers for stimulus preparation and presentation, response collection, and apparatus scheduling and control are presented. All of these functions may be performed by automated systems characterized by the amount of experimental integration and control performed by the computer. Systems types include on-line open-loop, on-line closed loop single or multiple purpose, and off-line. The multiple-man, multiple-purpose system which permits numerous automated investigations upon different source subjects to occur simultaneously is highlighted as the culmination of current automated behavioral analysis systems. But the possibility of behavioral scientists “tapping” into operating systems is presented as possibly having revolutionary consequences with respect to the data gathering of human behaviour. Finally, a general automated behavioral analysis system schematic assists in discussing current advantages, potential advances, and impending limitations of contributions of computers to the quantification of human behavior.

Operating Unit

The general cost structure of a unit on line is assumed to be governed by a stochastic process , where R(t) denotes the operating cost on [0, t)and ζ denotes the time of an unscheduled (or unplanned) replacement by a new unit at a cost c 1. For an age replacement maintenance policy, scheduled (or planned) replacements occur whenever an operating unit reaches age T, whereas in the block replacement case, scheduled replacements occur every T units of time. Such scheduled replacements cost c2. The expected long-run cost per unit time can then be expressed in the form A(T)/Ε [min(ζ, T)] and B(T)/T respectively. Our main result shows that where U is the associated renewal function generated by ζ.
