J. Castellano-Paulis A. Hernández-Mendo Verónica Morales-Sánchez M. T. Anguera-Argilaga 《Quality and Quantity》2007,41(1):93-104
We present a probabilistic model based on the one developed by Hernández Mendo and Anguera (Revista de Psicologíca Social,
16(1), 71–93, 2001). Here we have tried to break down the interaction contexts that the opposing teams are able to generate
and transform during the game. We are aware that a given player or team does not produce consistent behaviour in similar situations.
However, a degree of uncertainty is assumed to exist regarding whether the results obtained are a specific function of the
analysis used. In order to carry out this research a category system which optimized that used in the previous model was developed.
This system should enable the interaction between teams to be observed within the actual play of a soccer game. A lag sequential
analysis was performed on the basis of a coding of the behavioural flow. After describing the behavioural patterns obtained
a probabilistic model of the development of play in soccer is proposed. 相似文献

Do international labor flows influence the prospects for democratization both in the countries that export their excess workers and in the countries that import them? This paper argues that emigration should have a positive effect on political liberalization in net source countries because it decreases the amount of redistribution that would occur in a more democratic regime. Conversely, immigration should have a negative effect on political liberalization in net destination countries through the same causal channel: by increasing the amount of redistribution that would occur in a more democratic regime. South Korea and Singapore are considered as illustrative examples, and the paper provides statistical evidence to support the hypothesis that emigration (immigration) has been positively (negatively) related to future political liberalization. 相似文献

In this study both aggregate and industry‐level foreign direct investment (FDI) data are employed to investigate the spatial dependence of FDI hosts. The analysis contributes to the existing literature by focusing on the heterogeneous spatial correlation of FDI in different industries. Using more comprehensive FDI data across multiple industries and multiple provinces in China from 1999 to 2007, the results show a significant spatial correlation among provinces. Aggregate FDI tends to be regional trade platform oriented indicating neighboring provinces become competitors for FDI. In contrast, results based on industry‐level provincial FDI show stronger support for vertical or complex vertical FDI. 相似文献

The stock market crash of October 1987 earmarked fears of a deep-seated financial crisis. In recent years, while there has been a number of empirical studies devoted to examinations of the number of common trends in a system of stock price indexes, only a minority has focused on what effect the crash has had on the characteristics [namely, the amount of co-movements amongst markets, their dynamic linkages, and implications for the transmission or propagation mechanism] of major stock markets. In this paper, we demonstrate how the techniques of unit root testing, cointegration, vector error-correction modelling (VECM) and forecast error variance decomposition (VDC) analysis, may be used to shed some light on these concerns in the context of six major international stock markets. Using two non-overlapping samples, we find evidence of a single cointegrating vector (or five common trends) over each of the pre- and post crash samples. A VECM is then constructed in which the temporal causal dynamics are examined, followed by decomposing the total impact of an unanticipated shock to each of the variables beyond the sample period, into proportions attributable to shocks in the other variables including its own. Results tend to broadly indicate: (1) the crash does not appear to have affected the relative leading role played by the US market over other markets; (2) the German and, British markets seem to have become more dependent on other markets over the post-crash era relative to the pre-crash; and (3) provide confirming evidence that, in general, the crash has brought about a greater interaction amongst markets, with a greater role for fluctuations in explaining shocks across markets (including that for the U.S.). 相似文献
