The aim of this study is to analyze the effects of different modes of learning on innovation and profitability in SMEs in two Latin American countries; Mexico and Colombia. The data were obtained using a sample of 250 companies in the industrial sector operating in both countries. Results show that an integrated mode of learning based on internal and external knowledge supported by technological infrastructure have positive and significant effects on the degree of innovation and the profitability in SMEs However this effect appears to be not significantly different from the traditional SMEs mode of learning based mainly on market orientation. 相似文献

This study investigates the relationship between working memory and language in young children growing up in a multilingual environment. The aim is to explore whether mechanisms of short-term storage and cognitive control hold similar relations to emerging language skills and to investigate if potential links are mediated by related cognitive abilities. A sample of 119 Luxembourgish 6-year-olds completed several assessments of working memory (complex and simple span), native and foreign vocabulary, syntax, reading, rhyme awareness, and fluid intelligence. Results showed that short-term storage and cognitive control manifested differential links with developing language abilities: Whereas verbal short-term storage was specifically linked to vocabulary; cognitive control manifested unique and robust links with syntax and early reading development. The study suggests that in young children the working memory system is composed of separate but interacting components corresponding to short-term storage and cognitive control that can be distinguished by the roles they play in supporting language acquisition. 相似文献

ObjectivesTo determine the prevalence of intimate partner violence (defined as any physical violence during the last 12 months or previously) among mothers who maltreat their children, and to examine whether mothers’ experiences of intimate partner violence (IPV) are associated with repeated reports (rereports) of children to Child Protective Services (CPS) during the following 18 months.MethodsData for the analyses were from the National Survey of Child and Adolescent Well-Being (NSCAW), a national probability study of children investigated for child maltreatment. The sample of 5,501 children (ages 0–14) was randomly selected from the families who entered the US child welfare system between October 1999 and December 2000. The analysis sample was restricted to 1,236 families in which caregivers were: (1) the alleged perpetrators of the child maltreatment at baseline (independently of substantiation status) and (2) the biological mothers (n = 1,212 or 98.6%), adoptive mothers (n = 17 or 1%), or stepmothers (n = 7 or 0.3%) of children not placed in out-of-home care.ResultsChildren of mothers physically abused by an intimate partner during the last 12 months or previously at the intake interview (44%) were twice as likely as children of mothers who had not experienced such violence to be rereported to CPS (29% vs. 14%, Odds Ratio = 2.0, 95% Confidence Interval = 1.1–3.4). Rereports occurred almost twice as quickly for children of mothers who experienced IPV compared to children of mothers who had not experienced IPV (Hazard Ratio = 1.9, 95% Confidence Interval = 1.1–3.0).ConclusionsThe higher risk and speedier rereports of child maltreatment associated with intimate partner violence highlights the need for universal assessment and provision of services for IPV among families that are investigated by CPS. 相似文献

A constructivist-oriented inservice program provided teachers of mathematics (K-12) with intensive two-week summer institutes and weekly classroom follow-up. Pre- and post-program data on student outcomes indicate that, along with transformations in the nature and quality of mathematics activity in the classroom, students' beliefs about learning mathematics changed and elementary students' attitudes toward mathematics improved. Although the instruction they now received focused more on conceptual understanding and less on computational skill, students' scores on standardized tests assessing routine knowledge were maintained.An earlier version of this paper appeared in R. Underhill (ed.),Proceedings of the Thirteenth Annual Meeting of the North American Chapter of the International Group for the Psychology of Mathematics Education

Using a multiple case study approach across seven schools in the United States and Sweden that serve newcomer students exceptionally well, we identified the strategies they implemented across sites that served to meet the educational needs of these students. We found that these schools provided a comprehensive approach to support the socioemotional and academic needs of their newcomer students, identifying many common practices for improving outcomes for newcomer students. 相似文献

The relationship among achievement goals,standardized test scores,and elementary students’ focus in school 下载免费PDF全文
The study examined whether an academic, social, or both an academic and social focus might relate with achievement goals and academic achievement. Participants were 412 urban elementary school students. Results suggest that students with an academic focus toward school have more mastery‐approach and less mastery‐avoid achievement goals. Academic achievement (standardized test scores) did not relate with boys’ or girls’ focus toward school. These findings suggest that academic motivation, but not achievement, correspond with self‐perceptions of school as being a place to learn or school as a place for social interactions. 相似文献

Parents and researchers alike are interested in how to promote children’s academic competence. The present meta-analysis integrates the results of 308 empirical studies on associations of general parenting dimensions and styles with academic achievement of children and adolescents assessed via grade point average or academic achievement tests. Parental responsiveness (warmth), behavioral control, autonomy granting, and an authoritative parenting style were associated with better academic performance both concurrently and in longitudinal studies, although these associations were small in a statistical sense. Parental harsh control, and psychological control, as well as neglectful, authoritarian, and permissive parenting styles were related to lower achievement with small to very small effect sizes. With three exceptions, parenting dimensions and styles also predicted change in academic achievement over time. Moderating effects of child age, ethnicity, reporter on parenting and academic achievement, quality of the parenting and achievement measure, and publication status were identified. It is concluded that associations of academic achievement with general parenting dimensions/styles tend to be smaller than associations of school-specific parental involvement which have been addressed in previous meta-analyses. 相似文献

Suzy Q's is a retail business located in the southeastern United States. It offers hand‐knitted scarves; handmade hair accessories; handcrafted beaded jewelry such as necklaces, bracelets, and earrings; small handmade children's toys; and stock and custom‐printed T‐shirts. It began operations in early 2014. The owners established an online store and developed plans to sell items at local craft fairs and farmers’ markets in the southeastern United States. During its initial launch, the business generated limited orders for its products. In the beginning there was a limited amount of advertising using social media, which consisted of establishing a Facebook page, posting notifications on the business's Facebook page, and posting notifications about the business to the owners’ personal contacts on Facebook. Despite establishing a web presence and utilizing social media in its first year of operations, Suzy Q's did not generate a significant number of orders and received very little revenue. The owners of Suzy Q's, our client, established a goal to generate at least $700 per month in revenue for the calendar year 2015. Our analysis of the business revealed that the managers and employees had the skills needed to perform the work, but the lack of orders presented an obstacle to achieving their business goals. After completing a performance analysis, we recommended that Suzy Q's establish a single online presence, implement a marketing effort, establish a local presence, create a dedicated studio space, and create a formal business plan. It was our belief that Suzy Q's had the potential to reach its goals set for 2015 and beyond if these solutions were implemented. 相似文献
