The development of artificial intelligence (AI) technology expands the boundary of business practice, inducing the emergence and application of business intelligence (BI) that has promoted the transformation of information techniques to optimize business decision and operation. However, there is a lack of theoretical consensus and measurement of the technology embedded in BI at present. This study exploratively develops the Sense-Transform-Drive (STD) conceptual model of BI based on dynamic capabilities theory and organizational evolutionary theory to explain the core BI capabilities. By using factoring analysis and structural equation modeling analysis, we extract the latent constructs and empirically verify the validity of the STD model and further examine the correlation and mode of interaction of the three core BI capabilities and the impact of BI application on firm performance in the real economy with a sample contextual to Chinese business practices. The study results show that there are direct and high-intensity cumulative positive effects among the structural components of the STD conceptual model and BI-related dynamic capabilities can enhance operating efficiency and firm performance. 相似文献

近年来,我国HIV／AIDS呈加速流行趋势,性病发病率逐年上升,洁身自爱,拒绝性乱是阻HIV／AIDS和性病蔓延的有效措施。然而,调查资料表明,受威胁最大的青年人群中的大学生对婚前性行为持宽容态度日益增多,婚前性行为呈上升倾向。为此,必须加强高校性教育,大力倡导中华民族优秀的传统道德观,传授科学健康的性知识,促进大学生们为维护自身生殖健康,培养明的性态度、性观念和负责任的性行为,有效地遏制HIV／AIDS、性病的传播,让青年学生身心健身地成长。 相似文献

目的:了解大学生对性传播疾病的了解程度和对性教育的看法,以便为今后改进健康教育模式提供科学依据。方法:对中山大学602名学生进行问卷调查,所得数据用Excel建立数据库,进行统计分析。结果:大部分学生对性病有一定的认识,但对一些较为深入专业的问题以及如何防治缺少认识。绝大部分的大学生认为开展性健康教育是必要的。关于性知识的来源情况:主要来源于各种科普杂志、电影电视、报纸、朋友、专业宣传册,与学生希望的获得途径有较大的差异。这说明性知识的正规渠道来源不畅。结论:大学生对性病知识了解较少;大学生对性病艾滋病防治知识掌握的深度和广度不够,在高校开展性健康教育是必要的,要为青年学生补上这一课。 相似文献

The Centers for Disease Control and Prevention (CDC) recommends the HPV vaccination for boys and girls starting at age 11, yet adoption rates are low. We use eight focus groups to explore the decision making process, experiences, and social influences, including media and sex education classes, shaping attitudes of male and female college students. We find many students who have misinformation or no knowledge of the vaccination yet are eager to learn more. Due to youths’ range of knowledge about the vaccination and varied preparedness for making their own medical decisions, practitioners are in a challenging position to inform and encourage responsible decision making without appearing coercive. 相似文献

A computer- and Internet-based intervention was designed to influence several variables related to the prevention of pregnancy, STDs, and HIV in rural adolescents. Three-hundred and thirty-eight tenth-graders enrolled in two rural public high schools participated in this field experiment. Results indicate that students in the experimental school had greater knowledge, greater condom negotiation efficacy, greater situational efficacy, and more favorable attitudes toward waiting to have sex than students in the control school. In tandem, the results suggest that computer-based programs may be a cost-effective and easily replicable means of providing teens with basic information and skills necessary to prevent pregnancy, STDs, and HIV. 相似文献

Schools support teachers in their professional learning, just as teachers support students in their learning. To accomplish this, schools can provide support systems that enhance teachers’ knowledge, comfort, and instructional skills. This study examined the impact of two district-provided supports (curriculum and professional development) on sexual health instruction among middle and high school health education teachers. Data were abstracted and analyzed using inductive coding from 24 teacher interviews (2015–2016). Findings illustrate outcomes from both curriculum and PD on teachers’ self-reported knowledge, comfort, and skills. The district-provided supports appeared to contribute to improved teachers’ self-efficacy in delivering sexual health education. 相似文献
