ABSTRACT

The aims of this study were to identify profiles of sedentary behaviour (SB) patterns, based on leisure-time self-reported SB modalities (screen, educative, social, and relaxing) and to evaluate changes in these profiles over 2 years among Spanish youth aged 8–18 years. Latent profile analysis (LPA), a data-driven analytic approach, was used to identify groups of boys and girls (n = 1553; 48% girls; mean±SD age: 12.56 ± 2.49 y) with distinct SB profiles using the SB modalities (time/d) as input variables. Latent transition analysis, an extension of LPA that uses longitudinal data, was used to analyse 2-year changes in these profiles. At baseline, four and three SB profiles were found among boys (labelled: screen, educative, social, and relaxing) and girls (labelled: screen/social, educative, and relaxing), respectively. Overall, more girls (range: 48%-67%) had the same profile over time, than boys (40%-52%). Participants with a screen or relaxing SB profile at baseline were more likely to have an educative profile after 2 years. Youth with a social and an educative SB profile at baseline were more likely to transition to profiles characterized by higher screen and social SB, respectively. Using a novel and person-centered approach, this study identified gender-specific SB profiles that were moderately stable over time.  相似文献   

Decoding digital transformational outsourcing: The role of service providers’ capabilities     

《International Journal of Information Management》2021

The business process outsourcing industry has got disrupted, first by the significant shift in value creation activities from the clients to the service providers, and second by pervasive digital penetration, resulting in the emergence of Digital Transformational Outsourcing (DTO). Service providers now play a more significant role, making their capabilities important. In the new context, service providers require a uniquely different set of dynamic capabilities to handle end-to-end business functions on behalf of their clients while delivering digital value propositions.We study 26 of the largest global business process outsourcing providers to conceptualise and identify six dynamic capabilities of service providers salient in the new context, i.e., consultative, orchestration, insights, network management, knowledge access, and standardisation. Interviews conducted with industry experts provided evidence in support of the identified dynamic capabilities. A novel firm capability dataset was created using secondary data, and using fuzzy-set Qualitative Comparative Analysis (fsQCA), we identify configurations for high and low performance and find them to vary by the firm's broad/narrow scope.  相似文献

霍军 《湖北体育科技》2006,25(6):723-725

教师的专业化发展要求教师成为反思型教师,而反思型教师的成熟和发展离不开教育实践的锻炼和促进,只有将实践中反映出来的问题上升到理论层面加以反思,才能探寻到根源,使主体的合理性水平得到提升和拓宽.体育教师要坚持积极的自我反思与实践,以主体身份投入其中,扩大自己的专业视野,逐步养成教育反思的习惯,建立自我反思机制,成为反思型教师,同时促进教师专业化发展.  相似文献

建构主义学习理论对高校健美操教学的启示     

王萌  张士强 《沈阳体育学院学报》2004,23(5):704-705

建构主义学习理论倡导在教学过程中以学生为中心,充分发挥学生的能动性、积极性和首创精神,教师则起组织者、指导者、帮助者和促进者的作用。传统的以运动技术为中心的健美操教学已不能充分体现当今的体育教学改革的宗旨。以建构主义学习理论为指导,分别从教学方式、教学内容、教学评价三方面提出了新的教学思路,以期为我国高校健美操教学提供新的理论依据与实践指导。  相似文献
