In this paper, forecasting models for the monthly outgoing telephone calls in a University Campus are presented. The data have been separated in the categories of international and national calls as well as calls to mobile phones. The total number of calls has also been analyzed. Three different methods, namely the Seasonal Decomposition, Exponential Smoothing Method and SARIMA Method, have been used. Forecasts with 95% confidence intervals were calculated for each method and compared with the actual data. The outcome of this work can be used to predict future demands for the telecommunications network of the University. 相似文献

Recent methodological developments provide a way to incorporate the temporal dimension when accounting for spatial effects in hedonic pricing. Weight matrices should decompose the spatial effects into two distinct components: bidirectional contemporaneous spatial connections; and unidirectional spatio-temporal effects from past transactions. Our iterative estimation approach explicitly analyses the role of time in price determination. The results show that both spatio-temporal components should be included in model specification; past transaction information stops contributing to price determination after eight months; and limited temporal friction is exhibited within this period. These findings highlight the decidedly non-linear temporal patterns of such information effects. 相似文献

This paper examines commonality in liquidity for individual equity options trading in European markets. We use high-frequency data to construct a novel index of liquidity commonality. The approach is able to explain a substantial proportion of the liquidity variation across individual options. The explanatory power of the common liquidity factor is more pronounced during periods of higher market-wide implied volatility. The common factor's impact on individual options' liquidity depends on options' idiosyncratic characteristics. There is some evidence of systematic liquidity spillover effects across these European exchanges. 相似文献

This paper is the first attempt to estimate the determinants of holiday-taking across several countries. To accomplish this a two-stage estimation procedure is employed which enables incongruous income categories to be transformed into a single income variable. It is found that in the mid-1980s there was a substantial similarity in the holiday taking behaviour of Europeans. The large national differences in holiday participation are explained by differences in income and demographic factors. A remarkable regularity in the responsiveness of the probability of holiday taking to marginal changes in income is found. 相似文献

This paper investigates the link between governance and foreign direct investment in the case of 14 transition countries by using a panel gravity model approach in two alternative ways. First, the level of governance in the target country is studied. Second, the absolute difference in the governance level between the source and target country is investigated. In both cases the results suggest that the lack of good governance does not deter, in fact it encourages, foreign direct investment. 相似文献

Strategic tools are indispensible for business and competitive analysis. Yet we know very little about managers' internal logic as they put these tools into practical use. We situate our study in a business school context using action learning prior to the manifestation of practice to complement our understanding of practice. Using Personal Construct Theory and Repertory Grids, our mid‐range theorizing showed that, contrary to current thinking about strategic tools, managers think in dualities (often paradoxically) and have a preference for multiple‐tools‐in‐use, tools that provide different perspectives, peripheral vision, connected thinking, simultaneously help differentiate and integrate complex issues, and guide the thinking process. These findings are important for designing better tools and the nurturing of critical managerial competencies needed for a complicated world. Our study's focus also has wider implications for scholars as we see our own material evaluated by those who will put these lessons into practice. 相似文献

The relocation of Athens Airport provided a rare experimental context in which residents experienced significant changes in
noise levels due to the introduction or removal of aircraft noise. This paper reports the results from surveys around both
airport locations, using stated choice experiments to estimate values for aircraft noise. The respondents were offered actual
inter-temporal noise change scenarios rather than hypothetical variations, which is uncommon in the literature, incorporating
the presence or absence of an airport and other relevant transport attributes that also changed with the airport relocation.
Whilst there is some variation in the valuation of the airport closure and opening, when these values are adjusted to reflect
the actual change in decibels, there is remarkably little difference between the old and new airports. However, a significant
variation in aircraft noise values is identified between different areas, with respect to education and to a lesser extent
income. Our preferred estimate of the monthly household willingness to pay for terminating aircraft noise exposure is 13.12€
and for avoiding the onset of aircraft noise is 9.53€. 相似文献

Customer relationship management (CRM) remains an area of considerable interest in contemporary project management literature, due to its association with high failure rates. This research examined the criticality of four risk factors. Quantitative data analyzed using PASW17 were collected from a sample of 250 CRM project practitioners. Although we found strong evidence to support the focus on these risk factors, which include “user training,” “top management support,” “business strategy and technology alignment,” and “effective project feedback,” the authors found that, although some risk factors may be identified as “critical,” their criticality is dependent on the context of the project. 相似文献

Drawing from the norm of reciprocity, signal theory, and psychological contracts, we argue that the use of different types of political tactics, based on their social desirability, can be reciprocal behavioral reactions to contextual cues (i.e. perceptions of organizational support and politics) that can predict career success. Using a sample of 117 middle managers, our findings suggest that the use of sanctioned political tactics partially mediates the relationship between perceptions of organizational support and career success, while non-sanctioned political tactics suppress the relationship between perceptions of organizational politics and career success. 相似文献
