Analysis of the interplay between knowledge and performance management in industrial clusters

The concept of industrial clustering has been studied in-depth by policy makers and researchers from many fields, mainly due to the competitive advantages it may bring to regional economies. Companies often take part in collaborative initiatives with local partners while also taking advantage of knowledge spillovers to benefit from locating in a cluster. Thus, Knowledge Management (KM) and Performance Management (PM) have become relevant topics for policy makers and cluster associations when undertaking collaborative initiatives. Taking this into account, this paper aims to explore the interplay between both topics using a case study conducted in a collaborative network formed within a cluster. The results show that KM should be acknowledged as a formal area of cluster management so that PM practices can support knowledge-oriented initiatives and therefore make better use of the new knowledge created. Furthermore, tacit and explicit knowledge resulting from PM practices needs to be stored and disseminated throughout the cluster as a way of improving managerial practices and regional strategic direction.     

Federal funding and the rate and direction of inventive activity

Leveraging a new measure of patent citation trees (Corredoira and Banerjee, 2015), we demonstrate that research funded by the federal government is associated with more active and diverse technological trajectories. Our findings tie government funding to breakthrough inventions. The differences are especially evident at the upper percentiles of the distribution of long term patent influence and stem primarily from research conducted outside the federal government and sponsored by the DOD, HHS and NSF. Government funded patents are inputs into a broader range of technologies. Additional analyses indicate that federal programs invest in some technological areas that private corporations eschew, and federally funded university patents are in different technological classes than non-federally funded university patents. In this sense, the government may play an irreplaceable role in the rate and direction of inventive activity.“Generally speaking, the scientific agencies of Government are not so concerned with immediate practical objectives as are the laboratories of industry nor, on the other hand, are they as free to explore any natural phenomena without regard to possible economic applications as are the educational and private research institutions.” - Vannevar Bush, Science the Endless Frontier”, 1945.     

Relationship Between Language and Concept Science Notebook Scores of English Language Learners and/or Economically Disadvantaged Students

Despite research interest in testing the effects of literacy-infused science interventions in different contexts, research exploring the relationship, if any, between academic language and conceptual understanding is scant. What little research exists does not include English language learners (ELLs) and/or economically disadvantaged (ED) student samples—students most at risk academically. This study quantitatively determined if there exists a relationship, and if so, how strong of a relationship, between ELL and ED students’ academic language and conceptual understanding based on science notebook scores used in a larger science and literacy-infused intervention with a sample of culturally diverse students. The study also considered strengths of relationships between language and concept science notebook scores within student language status groups (ELL, former ELL, and English speaking). Correlational analyses noted positive, large, and significant correlations between students’ language and concept scores overall, with the largest correlations for science notebook entries using more academic language. Large correlations also existed for ELL student entries at the end of the school year. Implications of the findings for future research and practice in science classrooms including literacy interventions, such as science notebooks, with populations of culturally diverse students are discussed.     

Greater basal skeletal muscle AMPKα phosphorylation in men than in women: Associations with anaerobic performance

Objectives: This study was designed to investigate the association of gender, fibre type composition, and anaerobic performance with the basal skeletal muscle signalling cascades regulating muscle phenotype. Design: Muscle biopsies were obtained from 25 men and 10 women all young and healthy. Methods. Protein phosphorylation of Thr¹⁷²AMPKα, Ser²²¹ACCβ, Thr²⁸⁶CaMKII as well as total protein abundance of PGC-1α, SIRT1, and CnA were measured by Western blot and anaerobic performance by the Wingate test. Results: Percent type I myosin heavy chain (MHC I) was lower in men (37.1?±?10.4 vs. 58.5?±?12.5, P?P?P?221ACCβ and Thr²⁸⁶CaMKII fractional phosphorylation tended to be higher in men (P?=?.1). PGC1-α and SIRT1 total protein expression was similar in men and women, whereas CnA tended to be higher in men (P?=?.1). Basal AMPKα phosphorylation was linearly related to the percentage of MHC I in men (r?=?0.56; P?Conclusion: In summary, skeletal muscle basal AMPKα phosphorylation is higher in men compared to women, with no apparent effect on anaerobic performance.     

Cold-water immersion alters muscle recruitment and balance of basketball players during vertical jump landing

The purpose of this study was to evaluate the effects of cold-water immersion on the electromyographic (EMG) response of the lower limb and balance during unipodal jump landing. The evaluation comprised 40 individuals (20 basketball players and 20 non-athletes). The EMG response in the lateral gastrocnemius, tibialis anterior, fibular longus, rectus femoris, hamstring and gluteus medius; amplitude and mean speed of the centre of pressure, flight time and ground reaction force (GRF) were analysed. All volunteers remained for 20 min with their ankle immersed in cold-water, and were re-evaluated immediately post and after 10, 20 and 30 min of reheating. The Shapiro–Wilk test, Friedman test and Dunn’s post test (P < 0.05) were used. The EMG response values decreased for the lateral gastrocnemius, tibialis anterior, fibular longus and rectus femoris of both athletes and non-athletes (P < 0.05). The comparison between the groups showed that the EMG response was lower for the athletes. Lower jump flight time and GRF, greater amplitude and mean speed of centre of pressure were predominant in the athletes. Cold-water immersion decreased the EMG activity of the lower limb, flight time and GRF and increased the amplitude and mean speed of centre of pressure.     

“Should I let them talk?”: Private speech and task performance among preschool children with and without behavior problems

Preschool and kindergarten teachers must make decisions everyday about how much to allow their children to talk out loud to themselves during various classroom activities. The present study examines the effects of children's private speech use on task performance for a group of behaviorally at-risk children and a group of control children during a speech–action coordination task. Twenty-nine behaviorally at-risk preschool children and 43 control children completed two versions of a speech–action coordination task (motor sequencing version and numeric tapping) two times, once with and once without speech instructions. Results indicated that the behaviorally at-risk children used more speech spontaneously compared to control children and performed just as well, and that both groups of children performed better when given instructions to use speech. Implications of these findings for early childhood educators’ decisions about children's private speech use in the classroom are discussed.     

Technological learning and entrepreneurial behaviour: A taxonomy of the chemical industry in Venezuela

This paper presents a taxonomy of entrepreneurial behaviour vis-à-vis technology, derived from empirical research on a specific sector, that of the chemicals industry in Venezuela. The research focuses heavily on the accumulation of minor innovations through which enterprises acquire their technical knowledge and know how, their technological learning. We have tried to give a precise empirical meaning to that notion in order to understand which are the most important variables that affect the technical learning process. Both the process of technological learning and the technical external linkages — in particular with foreign firms — of Venezuelan companies seem to be the fundamental factors in understanding the development of a new competitive industry which adopts a new products-oriented strategy. But not all firms do respond to such a scheme and it is thus necessary to develop a taxonomy of the industrial sector both for scholarly reasons as well as a policy guide.
