This paper analyses how knowledge-based practices adopted by innovation intermediaries enable them to generate value for themselves when collaborating with their clients. While the literature focuses on value creation for their client organisations, little is known about how innovation intermediaries create internal value even though this is essential for ensuring their long-term survival and sustaining their key facilitating role in the innovation system. This understudied issue is explored using empirical evidence from a sub-set of innovation intermediaries, Research and Technology Organisations (RTOs). The results indicate that by capitalising on existing knowledge vested in employees and collaborators as well as understanding and shaping the knowledge base of the innovation ecosystem, innovation intermediaries generate internal value from their involvement in collaborative innovation, which range from different financial to non-financial types of value. Implications for intermediaries, their collaborators and for policymakers are then discussed. 相似文献

This study examines the viability of utilizing a dynamical system model and heuristic parameter estimation algorithm to make predictions for maximum heart rate (\(\mathrm {HR_{max}}\)) and maximal oxygen uptake (\(\dot{\mathrm {V}}{\mathrm {O_{2max}}}\)) using data collected from a submaximal testing protocol. \(\dot{\mathrm {V}}{\mathrm {O_{2max}}}\) is widely considered to be the best single measurement of overall fitness in humans. When a \(\dot{\mathrm {V}}{\mathrm {O_{2max}}}\) assessment is not available, \(\mathrm {HR_{max}}\) is often used to prescribe exercise intensities for training and rehabilitation. In the absence of maximal cardiopulmonary exercise testing (CPET), \(\mathrm {HR_{max}}\) and \(\dot{\mathrm {V}}{\mathrm {O_{2max}}}\) are typically estimated using traditional submaximal prediction methods with well-known limitations and inaccuracies. For this study, 12 regularly exercising healthy young adult males performed a bout of maximal CPET on a cycle ergometer to determine their true \(\mathrm {HR_{max}}\) and \(\dot{\mathrm {V}}{\mathrm {O_{2max}}}\). Participants also performed a submaximal bout of exercise at varied intensities. A dynamical system model and heuristic parameter estimation algorithm were applied to the submaximal data to estimate the participants’ \(\mathrm {HR_{max}}\) and \(\dot{\mathrm {V}}{\mathrm {O_{2max}}}\). The submaximal predictions were evaluated by computing the coefficient of determination \({R^2}\) and the standard error of the estimate (SEE) through comparisons with the true maximal values for \(\mathrm {HR_{max}}\) (\({R^2 = 0.96}\), SEE = 2.4 bpm) and \(\dot{\mathrm {V}}{\mathrm {O_{2max}}}\) (\({R^2 = 0.93}\), SEE = 2.1 mL kg\(^{-1}\) min\(^{-1}\)). The results from this study suggest that a dynamical system model and heuristic parameter estimation algorithm can provide accurate predictions for \(\mathrm {HR_{max}}\) and \(\dot{\mathrm {V}}{\mathrm {O_{2max}}}\) using data collected from a submaximal testing protocol. 相似文献

In today’s leading football training centres, state-of-the-art performance diagnostic systems such as the “Footbonaut” allow controlled and standardized assessments of physical and mental components of agility, e.g. speed of action and ball control, that are considered to be decisive for talent identification and development. However, effects of induced physical and mental strain on performing football-specific practice patterns remain to be elucidated, particularly in youth players, and, thus, characterize the purpose of this study. 33 randomly assigned competitive football players (U14 to U16) performed a standardized Footbonaut practice pattern (i.e. 20 balls randomly drawn at 50?km/h each), prior to and immediately after either mentally demanding tasks (MDT; n?=?11; continuous Vienna Test System’s Stroop task and determination test), physically demanding tasks (PDT; n?=?11; consisted of 4?×?4?min of football-specific high-intensity intervals with 3?min of active recovery in between) or a control condition (CON; n?=?11). Continuous heart rates (HR) as well as self-perceptions of fatigue were assessed. Main findings revealed performances for speed of action (p?=?0.44; f?=?0.01) and ball control (p?=?0.15; f?=?0.03) that were not modulated in the face of induced physical and mental strain as indicated by increased HR following PDT (p?<?0.001; d?>?0.8), or in the face of increased self-perceptions of fatigue following PDT and MDT (both p?<?0.001; both d?>?0.8) compared to CON. This is in line with a suggested talent factor and previous reports on motivational trade-off aspects in youth players. However, the present study’s short-timed practice patterns make it difficult to reliably compare a measuring sensitivity to complex football-specific movement behavioural and technical proficiencies with respect to mental and physical strain of longer-lasting football games and, thus, need further investigation in favour of improving talent identification and development using the Footbonaut. 相似文献

This interpretive study of change in Australian book publishing, included a survey of book publishers and the conduct of 14
case studies in five categories of publisher: general trade, academic, professional, specialist and university. This paper
reports in detail on the experience on one general trade publisher as it sought to face the challenges of globalization and
of organizational and technological change. The major finding was that digitization is indeed, impacting on business models
for book publishing, with current models comprising something of a hybrid between the traditional and the innovative. Reflecting
the presence in Australia of similar trends and issues that are affecting book publishing around the world, the findings are
of relevance both to book publishers and to researchers. The work is original in that relatively little recent academic research
has been conducted into book publishing in Australia, particularly as regards the implications of digitization for business
models. 相似文献

Given the relatively high intercorrelations observed between mathematics achievement, reading achievement, and cognitive ability, it has recently been claimed that student assessment studies (e.g., TIMSS, PISA) and intelligence tests measure a single cognitive ability that is practically identical to general intelligence. The present article uses three lines of reasoning to show that the outcomes of schooling can and must be conceptually distinguished from the intelligence construct. First, the conceptual differences between student assessments and tests of cognitive ability are delineated. Second, results from construct validation studies providing strong empirical support for the multidimensionality of the achievement measures applied in large-scale educational assessments are reported. Third, data supporting the differential development of educational outcomes in different domains are presented. 相似文献

Despite their potential, maker activities do not always support equitable engagement. The authors report on a design research study where they worked to support equitable engagement of youth repertoires of practice in a high school makerspace. Their orientation toward equity is grounded in the construct of repertoires of practice, and they focus on the question of what counts as making, and who has authority to decide. The authors consider two cases across two years and analyze moments of student resistance and agency as opportunities to expand the valued practices in the makerspace to more equitably support engagement. They report on the particular pedagogical strategies that emerged through the work, including exploration and helping, as well as their process of iterative analysis and design work that led to the embrace of these strategies. 相似文献

Offering academic programs that meet community need has long been a core mission of community colleges. However, determining which job skills and credentials are needed for employment in the community is challenging. In order to facilitate a holistic and community-based perspective, our 2-year community college developed a structured curricular planning model to guide programmatic decision-making based on regional economic and labor-market data. These procedures cumulatively inform comprehensive curricular planning related to program offerings and describe the relationship of this process to integrated planning. This model can assist other community colleges with designing processes to refine programing mix. 相似文献

This study of I-Kiribati secondary school teachers used a project-based approach to investigate the notions of school-based and collaborative learning as a suitable model for in-service teacher continuous professional development (CPD). The design and methodology adopted by the study framed the argument that since collaborative behavior is integral in Kiribati and Pacific community daily life it could be a suitably applied in the workplace to promote effective learning. At the same time the study was designed to investigate a system of learning for teachers in Kiribati that would address their needs, in particular being school-based. The study revealed that cultural influences in Kiribati such as: the role of leaders, respect for elders and secret knowledge have a strong influence on teacher behavior both inside and outside the classroom. The recommendations concur with research literature that suggests developing effective policy and practices in the Pacific region must be driven by and strongly reflect cultural practices, values and beliefs. Importantly, the notion that some cultural practices may conflict when applied in different settings provides an added dimension to the body of literature. 相似文献
