Innovation intermediaries and collaboration: Knowledge–based practices and internal value creation     

Muthu De Silva  Jeremy Howells  Martin Meyer 《Research Policy》2018,47(1):70-87

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   

Use of the Counseling Center Assessment of Psychological Symptoms 62 (CCAPS-62) as a Repeated Measure     

Arpita Ghosh  Sara Rieder Bennett  Juanita K. Martin 《Journal of College Student Psychotherapy》2018,32(2):151-162

The purpose of this initial, exploratory study was to examine the utility of the Counseling Center Assessment of Psychological Symptoms-62 (CCAPS-62) as a repeated measure tool at one university counseling center. This study investigated whether clients engaged in individual counseling changed in symptomology while in treatment and when (e.g., session) changes in symptomology occurred. To answer these research questions, reliable change indexes (RCIs) were calculated for each subscale of the CCAPS-62. Results indicated that all eight of the CCAPS-62 subscales demonstrated reliable changes from initial to subsequent administrations, and that changes occurred between sessions 3 and 6 at this specific university counseling center. Findings suggest the importance of incorporating CCAPS-62 information into counseling sessions to inform treatment and assessment.  相似文献   

A dynamical systems approach for the submaximal prediction of maximum heart rate and maximal oxygen uptake     

Michael J. Mazzoleni  Claudio L. Battaglini  Kerry J. Martin  Erin M. Coffman  Jordan A. Ekaidat  William A. Wood  Brian P. Mann 《Sports Engineering》2018,21(1):31-41

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

Eight-season epidemiological study of injuries in men’s international Under-20 rugby tournaments     

Colin W. Fuller  Aileen Taylor  Martin Raftery 《Journal of sports sciences》2018,36(15):1776-1783

The aim of this study was to define the incidence and nature of match injuries sustained in men’s international under-20 rugby. The study comprised an 8-season prospective study of 16 international under-20 rugby tournaments. Procedures complied with the consensus statement for epidemiological studies in rugby. Outputs included players’ mean age, stature and body mass and incidence, severity, location, type and cause of match injuries. The overall incidence of injury was 49.7 injuries/1000 player-match-hours (backs: 48.3; forwards: 50.9) with a mean severity of 32.2 days-absence (backs: 29.4; forwards: 34.4). There were no significant changes in incidence or severity of injury over the study period. Shoulder/clavicle (18.3%), head/face (16.4%), knee (13.7%) and ankle (13.7%) were the most common injury locations and ligament sprain (35.4%), haematoma/bruise (15.9%), concussion (12.5%) and muscle strain (11.2%) the most common types of injury. Being-tackled (29.2%), tackling (24.0%) and collisions (14.3%) were the most common events leading to injury. The results confirm that international under-20 rugby has a high incidence and severity of injury but the incidence is half that reported for senior international players. There was no significant change in the overall incidence of injury at the Under-20 level in the period 2008 to 2016.  相似文献   

Football practice with youth players in the “Footbonaut”     

Tobias Vogt  Simon Gassen  Sören Wrede  Jan Spielmann  Martin Jedrusiak-Jung  Sascha Härtel  Jan Mayer 《Sportwissenschaft》2018,48(3):341-348

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   

Visuelle Bewegungskontrolle geführter Kraftübungen bei jungen Erwachsenen und Senioren     

Christiane Lösch  Nico Nitzsche  Christian Maiwald  Daniel Zschäbitz  Martin Weigert  Henry Schulz 《Sportwissenschaft》2018,48(3):428-437

In the context of strength training in rehabilitation, visual movement control can be helpful to ensure correct movements. However, there are only a few studies that deal with the effectiveness of feedback during resistance exercises. To investigate the effect of feedback during guided exercise, 18 young adults (28.8?±?5.5 years) and 12 senior citizens (67.9?±?4.1 years) were tested. Subjects performed shoulder press exercises (3 sets, 15 repetitions) with and without visual movement control in a randomized order. On day 1, the subjects trained without load, and on day 2 they trained at 50% of their single repetition maximum. Joint articulation at the elbow was recorded using elbow extension and flexion. Autocorrelation was used to determine the reproducibility of movements. Subjects achieved better reproducibility of the movement with feedback than without (χ²?=?19.73; p?<?0.001). There was no effect of the load on motion accuracy (p?>?0.05), but the age group showed a significant effect (χ²?=?6.00; p?=?0.014). The younger group shows a higher degree of movement accuracy. In summary, visual movement control is useful in guided exercises to control movement execution. In clinical setting, this may be a way to control the motion performance of guided strength exercises and to ensure purposeful muscle work. Further studies should clarify the effect of visual feedback on the movement quality in unguided strength exercises.  相似文献   

Business Models in Digital Book Publishing: Some Insights from Australia     

Xuemei Tian  Bill Martin 《Publishing Research Quarterly》2009,25(2):73-88

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

Large-scale student assessment studies measure the results of processes of knowledge acquisition: Evidence in support of the distinction between intelligence and student achievement   总被引：1，自引：0，他引：1  

Jürgen Baumert  Oliver Lüdtke  Martin Brunner 《Educational Research Review》2009,4(3):165-176

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
