文章通过问卷调查的研究方法,从职业价值观、婚恋价值观、消费价值观、人生价值观、政治价值观、道德价值观等六个维度来分析80后、90后大学生价值观上的共性与差异,发现两者之间的代际差异并不是十分明显,以期推进大学生价值观研究未来可以走向深入。     

“80后”教师专业精神现状分析及对策探究

教师专业精神是教师在信念上、追求上充分表现出来的风范与活力,具有服务性、专门性、长期性、创新性、自律性等多方面特征,对促进教师专业化发展具有独特的作用和意义。“80后”教师是教师队伍中的新生力量,在“80后”教师专业精神和行为现状遭到社会质疑时,如何加强“80后”青年教师专业精神建设,就成为一个全新而重要的课题。必须采取弘扬传统、恪守底线、榜样导向、因势利导、人文关怀等策略,方能强化“80后”教师的专业责任精神、专业道德精神、专业进取精神、专业创新精神,以及优化专业精神环境,从而加快“80后”教师专业化发展进程。     

Nutritional evaluation of caseins and whey proteins and their hydrolysates from Protamex

Whey protein concentrate （WPC 80） and sodium caseinate were hydrolyzed by Protamex to 5%, 10%, 15%, and 20% degree of hydrolysis （DH）. WPC 80, sodium caseinate and their hydrolysates were then analyzed, compared and evaluated for their nutritional qualities. Their chemical composition, protein solubility, amino acid composition, essential amino acid index （EAA index）, biological value （BV）, nutritional index （NI）, chemical score, enzymic protein efficiency ratio （E-PER） and in vitro protein digestibility （IVPD） were determined. The results indicated that the enzymatic hydrolysis of WPC 80 and sodium caseinate by Protamex improved the solubility and IVPD of their hydrolysates. WPC 80, sodium caseinate and their hydrolysates were high-quality proteins and had a surplus of essential amino acids compared with the FAO/WHO/UNU （1985） reference standard. The nutritive value of WPC 80 and its hydrolysates was superior to that of sodium caseinate and its hydrolysates as indicated by some nutritional parameters such as the amino acid composition, chemical score, EAA index and predicted BV. However, the E-PER was lower for the WPC hydrolysates as compared to unhydrolyzed WPC 80 but sodium caseinate and its hydrolysates did not differ significantly. The nutritional qualities of WPC 80, sodium caseinate and their hydrolysates were good and make them appropriate for food formulations or as nutritional supplements.     

Scope and patterns of innovation cooperation in Spanish service enterprises

Examining 2148 innovating service firms from the Spanish Technological Innovation Panel 2004, this paper utilizes Latent Class Analysis to appraise the scope of innovation cooperation in services in the Spanish economy, in accordance with the growing weight of external information flows throughout innovation processes. The empirical evidence indicates that the nature of the service activity affects both the partner chosen and the cooperation intensity. The results lead to the creation of a typology of cooperation composed of three broad profiles: service firms intensive in techno-scientific cooperation, intensive in interactions with clients and a profile with low intensity in cooperation, called lonely innovators. The probability that a firm belongs to the latter profile is 59%, which makes it reasonable to affirm that innovation cooperation is not a common practice in Spanish innovating service enterprises. Innovation output variables have been included in order to examine the relationship between patterns of cooperation and innovation performance. The findings also underline the co-existence of different cooperation patterns within the same industry.     

由80/20到九法则所想到的

《长尾理论》和《世界是平的》两本图书所论述的现象带有普遍性。阅读习惯的无缝对接,再谈“概念图书馆”,数字统计谨防误区,文献结构比例由谁做主,是在《世界是平的》中所谈到的几个问题。世界是“平”的,旨在真正了解读者的阅读行为;从80/20到九法则,旨在说明利用一次也是利用,这种利用占据全部读者比重的绝大部分,值得重视。

体育赛事危机管理及其早期预警机制之研究

本文主要运用文献资料法,对体育赛事危机管理及其早期预警机制进行了初步研究。在本文中,作者首先对危机、危机过程及危机管理的涵义进行了探讨。在此基础上,作者进一步说明了什么是体育赛事的危机管理,进而指明了对体育赛事危机管理及其早期预警机制进行研究的意义。最后,作者提出了体育赛事早期预警机制指标体系及早期预警机制构建其他方面问题的一些建议。     

"80后"体育消费者购物决策风格及影响因素研究

运用问卷调查和数理统计法研究"80后"体育消费者的购物决策风格。通过探索性因子分析和验证性因子分析,发现"80后"体育消费者具有6种购物决策风格,包括冲动购物、难以决策、重视质量、追求品牌、品牌忠诚和价格敏感。采用分类树对影响购物决策风格的人口学特征进行进一步讨论,并用模糊聚类分析将"80后"体育消费者划分为3种类型。最后为企业制定合理的体育市场营销策略提出建议。     

基于“二八定律”与“长尾理论”的农村移动通信市场开拓策略研究

随着城市移动通信市场的逐渐饱和,未来市场发展和竞争的焦点将转移到农村市场。如何开拓农村市场已成为运营商必须思考的问题?随着"二八定律"实践式微,"长尾理论"的盛行,运营商需思考如何整合理论以支持新市场的开拓。文章从"二八定律"与"长尾理论"的研究视角,从宏观经济环境与行业趋势研究显示:农村市场和流量经营已经成为移动通信市场的双尾市场。同时从运营模式、核心业务与利基市场、技术支持平台三个层面提出了开拓农村移动通信市场的策略。
