Shifting the Perspective of the Research Librarian: A CoResearch Paradigm     

Pamela Carter Speaks  Sarah Burkhead Whittle  Carl Farinelli  Renée L. Cambiano  Ronald M. Cambiano 《The Reference Librarian》2015,56(4):259-273

This article proposes the coresearch engagement model (CoRE), which addresses how the academic research librarian can become a coresearch partner with any patron. The CoRE model is an interpersonal process and is founded upon the concepts of mutual respect, collaboration, reciprocity, and empowerment. Grounded in Howard Gardner’s multiple intelligences theory, Malcolm Knowles’ andragogical model, and guidelines from the Reference and User Services Association, CoRE has the potential to result in engagement for the librarian and patron. The CoRE model can be utilized in many ways including self-awareness and development for those who need and want to expand their abilities as a research librarian. It provides a theoretical framework and a knowledge base, in addition to giving a context for further development by expanding, comparing the related theories for further research, and implementing various applications suggested by this article.  相似文献   

Biofunctionalized nanoslits for wash-free and spatially resolved real-time sensing with full target capture     

Thierry Le?chlé  Chia-Fu Chou 《Biomicrofluidics》2015,9(3)

We propose biofunctionalized nanofluidic slits (nanoslits) as an effective platform for real-time fluorescence-based biosensing in a reaction-limited regime with optimized target capture efficiency. This is achieved by the drastic reduction of the diffusion length, thereby a boosted collision frequency between the target analytes and the sensor, and the size reduction of the sensing element down to the channel height comparable to the depletion layer caused by the reaction. Hybridization experiments conducted in DNA-functionalized nanoslits demonstrate the analyte depletion and the wash-free detection ∼10 times faster compared to the best microfluidic sensing platforms. The signal to background fluorescence ratio is drastically increased at lower target concentrations, in favor of low-copy number analyte analysis. Experimental and simulation results further show that biofunctionalized nanoslits provide a simple means to study reaction kinetics at the single-pixel level using conventional fluorescence microscopy with reduced optical depth.  相似文献   

Effectiveness during ball screens in elite basketball games     

Miguel-Ángel Gómez  Otavio Battaglia  Alberto Lorenzo  Jorge Lorenzo  Sergio Jiménez  Jaime Sampaio 《Journal of sports sciences》2015,33(17):1844-1852

Ball screens are one of the most frequently used tactical behaviour in elite basketball games. The aim of the present study was to identify their predictors of success related to time, space, players, and tasks performed. The sample was composed of 818 ball screens corresponding to 20 close games (mean differences in score of 3.1 ± 0.8 points) randomly selected from the playoff games of the Spanish Basketball League (2008–2011). Classification tree analysis (CHAID) was used to analyse which variable or combination of variables, better predicts effectiveness during ball screens. The main results allowed identifying interactions with dribbler actions after the screen and the orientation of the screen on the ball. The results showed no interaction with game quarter and quarter minute temporal-related variables in both analyses. The present findings allow improving coaches’ strategic plans that involve selecting the most appropriate offensive approach when performing ball screens.  相似文献   

Intentional thought dynamics during exercise performed until volitional exhaustion     

Natàlia Balagué  Robert Hristovski  Sergi Garcia  Daniel Aragonés  Selen Razon  Gershon Tenenbaum 《Journal of sports sciences》2015,33(1):48-57

Using a non-linear approach, intentional dynamics of thoughts were examined during constant cycling performed until volitional exhaustion. Participants (n = 12) completed two sessions at 80% W_max. Their (1) intrinsic thought dynamics (i.e., no-imposed thoughts condition) and (2) intentional thought dynamics (i.e., imposed task-unrelated thoughts condition; TUT) were recorded and then classified into four categories: internal and external TUT (TUT-I, TUT-E) and external and internal task-related thoughts (TRT-E, TRT-I). The probability estimates for maintaining each thought category stable, the rate of switching from one category to another, and the entropy dynamics along the testing procedure were assessed and compared through time phase. Friedman ANOVA tests revealed a significant effect of effort increase on thought contents only in the imposed TUT test. While TUT-I probabilities decreased significantly (P < .001) as effort increased, TRT-I probabilities increased (P < .05). Moreover, the entropy to the entire thought dynamics increased at the outset of task performance and decreased upon approaching volitional exhaustion (P < .001). As time spent in constant effort increased, and volitional exhaustion approached, task relatedness (TUT, TRT), direction (internal, external), and entropy of thought contents changed unintentionally providing further evidence for a nonlinear dynamics of attention focus.  相似文献   

Temporary Book Storage Using a Document Management Company     

Meredith Giffin  Kirsten Huhn  Andréa Harland 《资料收集管理》2019,44(1):46-68

Finding an appropriate temporary storage location for books and providing access to them is a significant challenge for libraries undergoing renovations. The current article describes the use of a document management company by an academic library to store 430,000 books for 8 months and provide a retrieval-on-demand service. Aspects covered include the selection of a commercial storage provider with its own retrieval service; details of the move to and from offsite storage; the integration of the service with library processes; communications and user feedback; book usage during the storage period; overall costs; and lessons learned from the experience.  相似文献   

Red pigment production by Penicillium purpurogenum GH2 is influenced by pH and temperature     

Méndez A  Pérez C  Montañéz JC  Martínez G  Aguilar CN 《Journal of Zhejiang University. Science. B》2011,12(12):961-968

The combined effects of pH and temperature on red pigment production and fungal morphology were evaluated in a submerged culture of Penicillium purpurogenum GH2, using Czapek-Dox media with d-xylose as a carbon source. An experimental design with a factorial fix was used: three pH values (5, 7, and 9) and two temperature levels (24 and 34 °C) were evaluated. The highest production of red pigment (2.46 g/L) was reached with a pH value of 5 and a temperature of 24 °C. Biomass and red pigment production were not directly associated. This study demonstrates that P. purpurogenum GH2 produces a pigment of potential interest to the food industry. It also shows the feasibility of producing and obtaining natural water-soluble pigments for potential use in food industries. A strong combined effect (p<0.05) of pH and temperature was associated with maximal red pigment production (2.46 g/L).  相似文献   

Child and Adolescent Predictors of Personality in Early Adulthood          下载免费PDF全文

Maria Wängqvist  Michael E. Lamb  Ann Frisén  C. Philip Hwang 《Child development》2015,86(4):1253-1261

This study investigated development of the Big Five personality traits from early childhood into adulthood. An initial group of 137 Swedish children were assessed eight times between ages 2 and 29 years. Initial decreases in extraversion leveled off in early adulthood; agreeableness and conscientiousness increased from ages 2 to 29; neuroticism initially increased, leveled off in later childhood and adolescence, and decreased throughout early adulthood; while openness to experience showed an initial increase, then decreased and leveled off in early adulthood. Individual developmental trajectories varied significantly, particularly in relation to gender. Personality traits became increasingly stable, and the fact that childhood scores predicted scores in adulthood indicated that personalities are fairly stable across this portion of the life span.  相似文献

What do families of the ‘professional and managerial’ class educate their children for? The links between happiness and autonomy     

Jordi Collet-Sabé  Antoni Tort 《British Journal of Sociology of Education》2015,36(2):234-249

Based on a qualitative study involving 124 professional and managerial class families in Catalonia (Spain), this paper describes the aims and objectives these families have for the education of their children. During the fieldwork, when asked what they were aiming for in the education of their children, almost all of the parents replied ‘for them to be happy’. But what kind of happiness are they talking about? What kind of education might lead to happiness? Drawing principally on the work of Kellerhals and Montandon and their ‘contractual model of education’ and Bauman’s concepts of ‘secondary security’ and ‘homo eligens’, although also taking into account the related contributions of Lareau, Vincent and Ball, Stefansen and Aarseth, and Kusserow, the paper aims to demonstrate the strong connection these families make between happiness and ‘absolute’ autonomy, understood as two sides of the same coin and seen, by the participants, as the guiding principle that should shape the way they bring their children up.  相似文献
