人口的急剧增加,森林被大量砍伐,大量农田建成城市和工厂,草原沙漠化,目前的气候变暖趋势速度空前,是五千年以来最剧烈的气候变化,将给地球环境带来一系列严重的后果。面对全球变暖的可怕后果,人类该如何应对全球变暖,该如何不在牺牲经济发展的同时与自然和谐相处?目前我国是世界第二大温室气体排放国,仅次于美国。面对如此形势,同时作为气候变化影响的最大受害者,中国政府深深感受到积极应对气候变化的必要性和重要性,政府采取了积极的应对气候变化政策加快建设国家气候变化应对科学工程。研究和掌握自然规律,准确把握人类活动与气候变化的关系,是促进人与自然和谐的基础和前提。 相似文献

2009年年末,在丹麦的哥本哈根上演了一部有4万多人出场,以应对全球气候变化为主要任务的大片,片名就叫“低碳时代”。万科董事长王石从哥本哈根世界气候变化大会回来后宣称,到2014年万科将全部用可以换算成碳减排的节能方式造房子,可见,低碳不仅仅意味着一种新的经济模式,还将带来低碳生活、低碳文化,低碳社会、低碳人生…… 相似文献

<正>在丹麦哥本哈根召开的气候变化大会,各国为遏制全球"碳排放",就气候变暖互不相让,争得面红耳赤。一边是暴雪与低温,另一边是全球变暖,我们不禁要问:这个地球到底怎么了?这是在变暖还 相似文献

Michael Poole Glenville Jenkins 《International Journal of Human Resource Management》2013,24(6):841-856
In this paper, developments in human resource management in manufacturing in modern Britain based on a national sample are examined. The organization and role of human resource management, employee involvement, training and development, work practices and rewards are all targeted for an assessment of current practices. This is a prelude for a contrast between manufacturing and non-manufacturing. The conclusion is that the similarities between manufacturing and non-manufacturing substantially outweigh the differences. By inference, too, developments in human resource management practices are likely to reflect changes in the broader environment of businesses (and differences between companies) rather than being specific to the main industrial sectors. 相似文献

Abstract Data on crop production are assembled for four provinces—Punjab, Sindh, North-West Frontier Province and Balochistan—for the period from 1980/81 to 2005/06 to examine inter-provincial differences in productivity growth rates. Propositions are put forward and examined to explain the superior productivity performance of Punjabi crop producers over those in Sindh and North-West Frontier Province, and the unusual productivity trends in Balochistan. The major factors relate to economic infrastructure and human capital. The impact of agricultural research is difficult to discern, and further work is required to assess the lagged effects of research expenditures on TFP growth. Explication des déséquilibres interprovinciaux dans l'augmentation de la productivité dans la production de cultures au Pakistan RÉSUMÉ On a rassemblé des données pour les quatre provinces suivantes: Penjab, Sindh, Khyber-Pakhtunkhwa, et Baloutchistan, pour la période 1980/81 à 2005/06, afin d'examiner les différences interprovinciales dans les taux d'expansion de la productivité. On présente et on examine des hypothèses pour expliquer le rendement supérieur des producteurs du Penjab par rapport à ceux du Sindh et du Khyber-Pakhtunkhwa, ainsi que les tendances de productivité inhabituelles du Baloutchistan. Les principaux facteurs se rapportent à l'infrastructure économique et au capital humain. L'impact de la recherche sur l'agriculture est difficile à établir, et des travaux supplémentaires seront nécessaires pour évaluer les effets décalés des frais de recherche sur l'expansion du TFP. Explicación de la desigualdad inter-provincial en el crecimiento de la productividad de la producción de cultivos en Pakistán EXTRACTO Se recopilan datos sobre la producción de cultivos de cuatro provincias: Punjab, Sindh, Provincia de la Frontera Norte-Oeste y Balochistan, durante el período de 1980/81 a 2005/06, para examinar las diferencias inter-provinciales en los índices de crecimiento de la productividad. Se plantean y examinan propuestas para explicar el mayor rendimiento de la productividad de los productores de cultivos Punjabi con respecto a los de Sindh y la Provincia de la Frontera Norte-Oeste, y las inusuales tendencias de la productividad de Balochistan. Los factores principales se relacionan con la infraestructura económica y el capital humano. El impacto de la investigación agrícola es difícil de discernir, y se requiere más trabajo para evaluar los efectos retrasados de los gastos de investigación en el crecimiento TFP. 相似文献

Isabella Proeller 《Public Management Review》2013,15(1):7-29
Abstract The article explores which reform trends are expected to play a significant role in the further development of local government in European countries. Analysis is based on an adopted Delphi survey of (mainly academic) local government experts from thirty-two countries. Results include a list of trends structured by the perceived importance for the coming ten years. Redistributing responsibilities and duties across levels of government constitute the highest ratings out of all trends. Furthermore, results do not provide clear evidence to support a shift from public management to governance as has recently been proclaimed in academic debate and literature. Management topics continue to be of great importance. Last but not least, clusters extracted point to different reform groups, which highlight more reluctant or enthusiastic attitudes to the relevance of the suggested trends of the study. 相似文献

西部外贸中小企业发展的战略选择 总被引:4,自引:0,他引:4
中小企业是西部地区外贸进出口的重要力量。据统计,2005年,西部地区中小企业的进出口额达156.03亿美元,占西部地区进出口总额的34.6%,同比增长37.5%,表现出强劲的发展势头,成为推动西部地区对外贸易发展的一支最具活力的力量。然而,与东部地区同类企业发展相比,由于受区域经济发展水平、思想观念、经营环境以及政策等多种因素的影响和制约,西部外贸中小企业的发展还明显滞后。 相似文献

Smith LS 《Hospital materiel management quarterly》1998,20(1):61-69
Materiel managers are faced with a shrinking world and changing work environment. The needs and expectations of the customer have shifted because of the increasing number of multicultural groups. These groups will continue to assert their right to culturally sensitive care. Materiel managers also need to learn to support and enhance the skills of a multicultural work force. One important tool for change will be technology. However, technology that brings the world closer together also creates new challenges for managers, who will have to deal with multicultural colleagues, buyers, sellers, and manufacturers of goods and services. 相似文献

《Journal of econometrics》1986,31(1):93-118
Panel data based studies in econometrics use the analysis of covariance approach to control for various ‘individual effects’ by estimating coefficients from the ‘within’ dimension of the data. Often, however, the results are unsatisfactory, with ‘too low’ and insignificant coefficients. Errors of measurement in the independent variables whose relative importance gets magnified in the within dimension are then blamed for this outcome.Errors-in-variables models have not been used widely, in part because they seem to require extraneous information to be identified. We show how a variety of errors-in-variables models may be identifiable and estimable in panel data without the use of external instruments and apply it to a relatively simple but not uninteresting case: the estimation of ‘labor demand’ relationships, also known as the ‘short-run increasing returns to scale’ puzzle. 相似文献
