The climate for entrepreneurship at higher education institutions

While the importance of a supportive context for entrepreneurship is widely acknowledged, its antecedents are rarely investigated. We apply the concept of organizational climate to higher education institutions and examine the drivers of students’ perceptions of the entrepreneurial climate in their university. Combining data from two unique datasets and using multilevel techniques, we analyze the relationship between university characteristics and such climate perceptions of 8009 students at public universities in Germany. We find university entrepreneurship measures to have a positive effect on students’ climate perceptions, which also depend on students’ background and gender. In addition, we find evidence for different peer effects, depending on students’ affinity for entrepreneurship. For the general student population, including entrepreneurship content in their normal studies seems to be required to initiate a social process of sensemaking. However, students’ perception of the entrepreneurial climate only depend to a certain degree on intentional entrepreneurship measures. In our study, general university characteristics have the strongest influence on climate perceptions. Overall, our study adds to our understanding of which parameters are important for establishing a more favorable and inspiring climate for becoming an entrepreneur at higher education institutions.     

Cyclic electron flow around photosystem I is required for adaptation to high temperature in a subtropical forest tree, Ficus concinna

Dissipation mechanisms of excess photon energy under high-temperature stress were studied in a subtropical forest tree seedling, Ficus concinna. Net CO2 assimilation rate decreased to 16% of the control after 20 of high-temperature stress, and thus the absorption of photon energy exceeded the energy required for CO2 assimilation. The efficiency of excitation energy capture by open photosystem Ⅱ (PSII) reaction centres (Fv'/Fm') at moderate irradiauce, photochemical quenching (qp), and the quantum yield of PSII electron transport (φPSII) were significantly lower after high-temperature stress. Nevertheless, non-photochemical quenching (qHP) and energy-dependent quenching (qE) were significantly higher under such conditions. The post-irradiation transient of chlorophyll (Chl) fluorescence significantly increased after the turnoff of the actinic light (AL), and this increase was considerably higher in the 39 ℃-grown seedlings than in the 30 ℃-grown ones. The increased post-irradiation fluorescence points to enhanced cyclic electron transport around PSI under high growth temperature conditions, thus helping to dissipate excess photon energy non-radiatively.     

《庄子》音乐美学思想在“道”上的发展创新

《庄子》以"道"为本,继承发展了《老子》的音乐美学思想。在美乐标准上,《庄子》把《老子》的"音声相和"发展为"与道相和";在音乐批判上,《庄子》把《老子》批判"五音"发展为批判"违道"之乐;在音乐美学境界上,《庄子》把《老子》的"大音希声"的"悟道"境界发展为"载道"境界;在音乐审美上,《庄子》把《老子》的"过客止"的外在审美发展为"所乐"的内在审美。《庄子》在《老子》音乐美学思想的基础上,有令人瞩目的开拓创新,揭示了"道家"音乐的本源:生于心,源于物,随于道;揭示了"道家"音乐的基本功能是"和";揭示了"载道"之乐的"人为"、"有声"特点;揭示了"道家"音乐审美的心理历程。     

浅谈数学教学的“生活味儿”

让数学走进生活是新课标的要求。让课堂生活化,引导学生在生活情境中感受数学,体验数学源于生活的真正含义,对提高数学教学效果具有事半功倍的作用。但同时切忌把数学生活化片面理解,而从一个极端走向另一个极端。     

柔嫩艾美耳球虫(广东株)子孢子折光体抗原p28基因的分析

将克隆的柔嫩艾美耳球虫广东株p28基因与柔嫩艾美耳球虫MerckstrainLS18株的折光体抗原p28基因和USDA－APIno．24株折光体抗原GX3262基因进行了序列比较．发现广东株和MerckstrainLS18株的折光体抗原核苷酸序列和氨基酸序列的同源性分别为99．9％和100％，且基因内富含AGC重复顺序；而GX3262的基因序列为P28基因C-端的组成部分，并无特别的疏水和亲水区．

Efficacy of an early intervention education program for moderately handicapped infants

This paper focuses on the evaluation of special education services for handicapped infants. The research question posed is whether early intervention programming results in reduced need for specialized services when children are age-eligible for elementary school. The primary focus of the paper is the development of a predictive model which may be useful in assessing the efficacy of early intervention services. The predictive model is applied using longitudinal data from a small sample of moderately handicapped infants. The preliminary findings support the contention that earlier intervention results in a lessened need for special education services in subsequent years. The paper also discusses the benefit-cost issues related to the efficacy question under investigation.     

同质异构:早期创造社自叙小说比较论

自叙小说渗有浓郁的情感色彩,这情感源于创造社三位作家的自身经历和特定时代背景,郭沫若的自叙传在表达情绪上洋溢着诗人般浪漫色彩,极力倾泻;郁达夫则表现为低声呻吟,概叹人生苦闷生活艰辛;张资平采用冷峻的客观描摹,让情绪从生活事象中流溢出来。此为三家传情的迥异之处。     

《周易》筮法模式下的揲扐计算通用公式

对《周易》筮法中用于确定爻符的揲计算方法进行了研究,发现至少需要使用四个量:总策数T、揲策数M、变易次数C和最小结果数R,才能对这种算法进行较全面的数学描述。这些量在揲计算定理中表达为T=(R 2C)M。     

试析美国一战时的经济动员

一战以前的美国战争动员专注于人力动员，经济动员未受到应有的重视。美国政府从历次战争，特别是宣扬总体战的内战的经验教训中。认识到了经济总动员的重要性。一战时，美国采取了对经济进行全面动员的措施，从而保障了战争的胜利。
