影响高校男子400米栏运动员成绩的主要因素分析

男子400米栏作为田径比赛的一个重要组成部分,在我国的发展相对滞后,与欧美国家存在很大差距。为促进我国男子400米栏成绩的提高,本文对影响高校男子400米栏运动员成绩的主要因素进行了调查研究。本文采用分组随机抽样的方法,通过文献资料的收集,充分运用观察法、数理统计法、比较分析法深刻剖析得出平跑速度、跨栏技术以及栏间节奏是制约和影响高校男子400米栏运动员成绩的主要因素,并据此提出相关建议以达到提高高校男子400米栏运动员成绩的目的。

Why do statistics journals have low impact factors?

In this paper, we answer the question why statistics journals get lower impact factors than journals in other disciplines. We analyze diffusion patterns of papers in several journals in various academic fields. To obtain insights into the diffusion of the citation counts of the papers, the data are analysed with the Bass model, leading to values for the time-to-peak that can be used to compare the speeds of diffusion paper citations of the different disciplines. Estimation results show that for statistics journals, it takes significantly more years to reach their peak. To further investigate diffusion, we also compute the percentages of the total number of citations a paper has after 2 or 3 years. Again, it appears that statistics journals have slower citation diffusion than journals in other disciplines. We conclude with some suggestions to reduce this disparity.

Optimal money supply in models with endogenous discount factor

This paper studies the Friedman rule for the optimal quantity of money in money in the utility (MIU) and cash–credit models while considering two specifications for the endogenous discount factor. In the first specification, the discount factor depends directly on the utility level. In the second, the discount factor depends on every component of the utility function. We show that under the former specification the Friedman rule is the optimal policy. Under the latter, however, while the Friedman rule is optimal for the MIU model, it is not optimal for the cash–credit model.     

MBTI Personality Types of Project Managers and Their Success: A Field Survey

This paper describes a survey of 280 project managers that reveals both their personality types (via Myers‐Briggs personality inventory) and their success in project management. The results show that a project manager's personality is better suited for functioning with partial data and under ambiguity than the rest of the population. These traits were found for both women and men. The conclusion is that project managers (females and males) have a unique personality‐type distribution that distinguishes them from the general population. The findings can contribute to better understanding the traits that characterize the project management population, and their relationship to project success.     

A Spatial Multilevel Analysis of Italian SMEs' Productivity

Abstract

In this paper, we adapt multilevel analysis methods to investigate the spatial variability of SMEs' productivity across the Italian territory, and account for differences in the socio-economic context. Our results suggest that to properly capture the variability of the data, it is important to allow for both spatial mean and slope effects. Social decay has the expected negative impact. However, while this effect is larger on firms with smaller capital intensity, firms with higher capital intensity seem to be less affected by geography. Greater territorial heterogeneity emerges among those firms with lower capital to labour ratios.

Une analyse spatiale á plusieurs niveaux de la productivité de PME italiennes

Résumé dans la présente communication, nous adaptons des méthodes d'analyse à plusieurs niveaux pour examiner la variabilité spatiale de la productivité de PME sur l'intégralité du territoire italien, et évaluer les différences sur un plan socio-économique. Nos résultats indiquent que pour saisir correctement la variabilité des données, il est important de tenir compte à la fois de la moyenne spatiale et des effets des pentes. La désintégration sociale a l'effet négatif escompté. Toutefois, tandis que cet effet est plus important pour des entreprises à moindre intensité capitalistique, les entreprises à intensité capitalistique majeure semblent être moins affectées par des facteurs géographiques. On relève une hétérogénéité majeure parmi les entreprises au ratio capital/main-d’?uvre inférieur.

Un análisis espacial de niveles múltiples de la productividad de pequeñ as y medianas empresas italianas

Extracto En este trabajo, adaptamos métodos de análisis de niveles múltiples para investigar la variabilidad espacial de la productividad de pequeñas y medianas empresas a lo largo del territorio italiano, y tenemos en cuenta las diferencias dentro del contexto socioeconómico. Nuestros resultados sugieren que para capturar apropiadamente la variabilidad de los datos, es importante tener en consideración los efectos de la pendiente y media espacial. El deterioro social tiene el efecto negativo esperado. No obstante, aunque este efecto es mayor en las empresas con una intensidad de capital menor, las empresas con una mayor intensidad de capital parecen estar menos afectadas por la geografía. Una mayor heterogeneidad territorial emerge entre las empresas con relaciones más bajas entre capital y mano de obra.
