平台的构建模式及平台的治理方式研究

随着分工的不断深化,企业间的竞争战略已经从企业的个体行为转向群体合作,平台组织成为主流的产业组织形式。核心企业构建平台主要由两种模式：先积累用户规模再吸引关联企业的模式和先关联利益相关企业再向消费者传递价值的模式。由于机会主义的存在,平台治理必不可少,以内部治理为主,外部治理为辅的多主体共同参与的平台治理模式已经成为平台治理的主流模式。     

试论我国内部审计制度变迁对民营企业的影响

在我国内部审计制度发展之初,政府无意干涉民营企业内部审计制度的建立。随着民营企业的发展,基于提高自身经营活动的效益性需要,民营企业自发地开展了内部审计工作。但民营企业内部审计的自主发展存在诸多弊病。随着我国内部审计制度的发展和完善,民营企业内部审计逐渐被纳入政府统一管理的范围。民营企业内部审计工作在制度的推动下必将得到进一步的发展。     

行政抵抗权之法理分析

目前众多国内外的学者纷纷进行对相对人的抵抗权的研究,我们国家相关法律也对此做了一些类似规定。但是,我国行政法对于相对方的抵抗权的规定一直处于"犹抱琵琶半遮面"的状况,只在为数不多的法律文件中做了规定,因此作者认为行政相对方抵抗权已经能够在我国法律体制中发现,但是需要对其进行系统分析研究。     

培养基含水量对平菇抗杂菌能力胞外PH值及生物转化率的影响

本实验证明，培养基含水量70％有利于提高菌丝的抗杂能力，有利于提高生物转化率，且胞外PH值下降最迅速。培养基含水量在75％以下时，含水量越高出菇潮次越多。培养基含水量过高过低是影响杂菌污染率的最主要因素之一。建议实际生产中培养基含水量在65％－75％之间较为适宜。     

“七月诗派”抗战时期在桂林的诗歌创作

“七月诗派”作为一个在腥风血雨的严峻现实中崛起的高歌救亡的诗歌流派,这些诗人们在抗战炮声响起之后分别在根据地、敌后、国统区从事着民族的解放运动。由于当时桂林处于特殊的地理环境和政治地位,使得一部分“七月派”诗人先后驻足于桂林。他们在桂林的诗歌创作及活动,极大地繁荣了抗战时期的桂林诗坛,声援了全国的抗战斗争。     

儿童急性呼吸道感染中流感嗜血杆菌的检测与分型

目的 :为了解儿童急性呼吸道感染中的流感嗜血杆菌与生物分型及其对抗生素的敏感情况。方法 :对 78例急性呼吸道感染儿童采用常规方法进行了培养 ,药敏试验与生物分型。结果 :共分离出流感嗜血杆菌 33株 ,检出率为 4 2 .3% ,在对所有分离株进行的生物分型结果中 ,共检出 5型 ,其中以Ⅳ ,Ⅵ型居多 ,分别为Ⅳ型 8例 (2 4 .2 % ) Ⅵ型 13例 (39.4 % )。 33株分离出的流感嗜血杆菌中 ,全部菌株对氯霉素 ,氧氟沙星敏感 ,头孢拉定株 2 1(6 3.6 % ) 、头孢唑林 19株 (5 7.6 % )、去甲万古霉素 2 3株 (6 9.7% ) 、苯唑青霉素 31株 (93.4 % ) 、复方磺鞍甲基异唑 11株 (33.3% )、红霉素 4株 (13.2 % )。结论 :儿童急性呼吸道感染中流感嗜血杆菌有较高的检出率 ,以生物Ⅵ型和Ⅳ型居多。流感嗜血杆菌存在着严重的耐药倾向。     

Effect of obesity and insulin resistance on diabetic control

Diabetes Mellitus in obese and non-obese Indian individuals.AIMS: Effect of Obesity and insulin resistance on diabetic control.SETTINGS AND DESIGN: 50 each groups Diabetic individuals obese and non-obese.METHODS AND MATERIAL: On selected 50 each group diabetic patient and normal, following blood investigations has been performed—Plasma Glucose, Glycohemoglobin and Serum Insulin.STATISTICAL ANALYSIS USED: Individuals patient’s results were analyzed and compared with the normal controls.RESULTS AND CONCLUSION: The changes in glycosylated haemoglobin are mainly proportional to the post lunch glucose level (r=0.773) (p<0.01) and not correlated to circulating insulin or the body mass index. However the levels were higher in obese diabetes (Type I and II both) than in non-obese. Mechanism of resistance in insulin receptor interactions due to obesity is well known. However, obesity does not seem to affect directly glycosylated haemoglobin. Under such circumstances, the reduction of weight for a diabetic person can improve sugar control by minimizing insulin resistance and thereby can improve glycosylated haemoglobin levels.     

Effects of user experience on user resistance to change to the voice user interface of an in‑vehicle infotainment system: Implications for platform and standards competition

This study examines the effects of user experience on user resistance to change—particularly, on the relationship between user resistance to change and its antecedents (i.e. switching costs and perceived value) in the context of the voice user interface of an in-vehicle infotainment (IVI) system. This research offers several salient findings. First, it shows that user experience positively moderates the relationship between uncertainty costs (one type of switching cost) and user resistance. It also negatively moderates the association between perceived value and user resistance. Second, the research test results demonstrate that users with a high degree of prior experience with the voice user interface of other smart devices exhibit low user resistance to change to the voice user interface in an IVI system. Third, we show that three types of switching costs (transition costs, in particular) may directly influence users to resist a change to the voice user interface. Fourth, our test results empirically demonstrate that both switching costs and perceived value affect user resistance to change in the context of an IVI system, which differs from the traditional IS research setting (i.e. enterprise systems). These findings may guide not only platform leaders in designing user interfaces, user experiences, and marketing strategies, but also firms that want to defend themselves from platform envelopment while devising defensive strategies in platform and standards competition.
