Knowledge has become the main competitive tool for firms. Just as knowledge is considered as the most important strategic resource, knowledge management (KM) is considered to be critical to a firm’s success. Several attempts have been undertaken to identify and define the different KM processes. From the literature review, four key dimensions stand out as affecting KM processes: knowledge creation, knowledge transfer, knowledge storage/retrieval, and knowledge application. The aim of this paper is to contribute to the KM and value literature by determining the importance of the different processes of KM for increasing value creation and value capture in firms. The context for the research hypotheses is the Spanish banking industry in 2010. The results support a positive relationship between KM and value creation, and between value creation and value capture. 相似文献

Initiatives to integrate technology in schools are continuously increasing, with efforts to bridge the “homework gap” and provide technology access in low-income households. However, it is critical to include nondominant parents in technology adoption decisions in order to avoid mirroring past patterns of inequality in home-school relationships. This study examines the digital access, use, and beliefs of Spanish-dominant immigrant parents, whose children attended a school in early stages of 1:1 (one laptop, one child) and BYOD (bring-your-own-device) initiatives. Informed by critical and ecological approaches to family literacy and technology use, the analysis compares the cases of eight parents attending technology workshops facilitated by the researcher and looks at the factors and contexts shaping their digital access and use and their shifts in access over two years. The analysis then narrows down to their beliefs about the use of school-provided devices. Findings illustrate the diversity in device use and customization in families with similar immigration trajectories, showing how economic factors, education, and established livelihoods in the community shaped their decisions to obtain devices and Internet connectivity. Cases also show the crucial role of the school in providing computers and technology training; however, decisions about taking school devices home and supervising children's activity were shaped by parents' beliefs about their roles supporting their children's moral education, and their existing family practices. Implications for family literacy programs and outreach for digital equity in new migration settings are discussed. 相似文献

The paper investigates the existence of an Open Regional Innovation System (ORIS model). This model is characterised by the firms’ adoption of an open innovation strategy, which overcomes not only the boundaries of the firms but also the boundaries of the region.Using data collected in a sample of life science firms, our research provides the evidence that the Emilia Romagna RIS has evolved towards an ORIS model, where firms’ innovation search strategy, despite being still embedded in local nets (involving several regional public research organisations - PROs), is open to external-to-the-region research networks and knowledge sources. It also shows that innovation openness influences significantly the firms’ innovative performance. 相似文献

Item Response Theory (IRT) models were applied to investigate the psychometric properties of the Arthur and Day's Advanced Progressive Matrices-Short Form (APM-SF; 1994) [Arthur and Day (1994). Development of a short form for the Raven Advanced Progressive Matrices test. Educational and Psychological Measurement, 54, 395–403] in order to test if the scale is a reliable and valid tool to assess general fluid ability in a short time frame. The APM-SF was administered to 2264 high-school and university students. Once attested the one-factor structure of the scale, unidimensional IRT analyses for dichotomous data were applied to investigate the increases in item difficulty levels, Test Information Function, and Differential Item Functioning across age, gender, and country (comparing Italian and British respondents). Additionally, validity measures were reported. Findings attest that the Arthur and Day's APM-SF is a sound instrument for assessing fluid ability within a short time frame. 相似文献

Verbal memory is a fundamental prerequisite for language learning. This study investigated 7‐month‐olds' (N = 62) ability to remember the identity and order of elements in a multisyllabic word. The results indicate that infants detect changes in the order of edge syllables, or the identity of the middle syllables, but fail to encode the order of middle syllables. This suggests that the representational format of multisyllabic words is determined by core mnemonic biases, which favor accurate encoding of edges and limits the encoding of temporal order for internal segments. The studies support accounts proposing that content and order are encoded separately; in addition, the data show that this dissociation occurs early in development. 相似文献

ABSTRACT Studies on running biomechanics and energetics are usually conducted on a treadmill. To ensure that locomotion on a treadmill is comparable to locomotion overground, participants need to be expert in the use of the device. This study aimed to identify the number and duration of sessions needed to obtain stable measurements for spatiotemporal and metabolic parameters in unexperienced treadmill runners. Fourteen male recreational runners performed three 15-min treadmill running trials in different days at a submaximal speed. Spatiotemporal and metabolic parameters were registered at minutes: 5, 10, 15 and their within-trial and between-trial changes were analysed using a two-way repeated measures ANOVA and Bonferroni post-hoc test. Within-trial differences were found in step frequency (decreased over time), Step Length and Contact Time (increased), reaching stability at different time points. Ventilator parameters increased, reaching stability after 5–10 min, while heart rate increased progressively over time. The only between-trial differences were an increase in step length and a decrease in step frequency at min 1, between trials 1 and 3. In conclusion, at least three running trials of 15 min are required to familiarize with the device. The last 5 min of the third trial can be regarded as stable measurements. 相似文献

The experience of interest is central to intrinsic motivation for learning, so it is important to understand the nature of interest and its sources. Individual differences in fluid intelligence (Gf) predict finding things more interesting, but it is possible that this effect is merely due to the overlap of Gf with openness to experience, a strong predictor of interest across many domains. The present research measured Gf, the Big Five traits, and the interestingness of contemporary poems and visual art. Latent variable models found that Gf predicted interest in both poems and pictures, even when openness and gender were included as predictors. Moreover, Gf and openness did not interact, indicating main effects rather than joint effects. The relationship between Gf and interest thus appears robust. 相似文献

Division-With-Remainder (DWR) problems are particularly complex, as suggested in many studies. The purpose of this work was to establish whether students’ difficulties in DWR problems came from an inadequate initial representation or from an inadequate final interpretation of the numerical answers, and whether remainders could be grouped into two blocks depending on the kind of answer, either directly matching the terms of the division or not. Forty-five Spanish secondary students, aged 12–13, were requested to solve two Types of Division Situations (i.e., Equal Groups and Comparison), each one involving four Types of Remainder (i.e., Remainder-Not-Divisible, Remainder-Divisible, Remainder-as-the-Result, and Readjusted-Quotient-by-Partial-Increments). Our data showed that: (a) the selection of the correct solution procedure depended on the Type of Division Situations, being easier in Equal Groups than in Comparison problems; (b) correct interpretations were higher than the percentages reported in other researches; and (c) success in problems whose answers were the quotient or the remainder was higher than in Readjusted-Quotient-by-Partial-Increments problems. The results obtained suggest that students’ difficulties originate in the initial representation of the DWR problems and that it would be more adequate to refer to the difficulty of Readjusted-Quotient-by-Partial-Increments problems in particular, rather than to the difficulty of DWR problems in general. 相似文献

We conducted a literature review of using educational technology in biology learning from 2001 to 2010. A total of 36 empirical articles were included for review. Based upon the content analyses of these studies, such as technologies utilized, student sample, biological topics involved, the research purpose, and methodology, the following observations were revealed. Among the different types of technologies, the majority of studies utilized simulations or visualization tools. Genetics and molecular biology were the most popular biological topics. Most studies examined students’ conceptual outcomes, fewer studies examined affective outcomes, and a few studies examined higher-order skills. Also a small number of studies observed students’ learning processes. Beyond simply the comparison for traditional teaching versus technology-assisted learning, some studies emphasized comparing different technologies or different representations. This review also suggested some future research directions. For example, more studies should use technologies for interdisciplinary training and for fostering problem-solving skills. 相似文献
