Interaction of the originality of peers’ ideas and students’ openness to experience in predicting creativity in online collaborative groups

There has been growing interest in the possibility that peers’ ideas can stimulate students’ creativity in group contexts. However, empirical research on this issue is limited. This study tested the hypothesis that peers’ ideas and students’ openness to experience would predict student creativity and attention to peers’ ideas. Undergraduate students (n = 60) completed creative tasks in an online collaborative group in which the ideas of “peers” were pre-programmed. Mixed ANOVAs showed support for the hypothesis. Specifically, students with higher (but not lower) openness, when exposed to a high (but not low) rate of peers’ original ideas, paid greater attention to those ideas and were more creative. The implication for education is that teachers should encourage students to share more of their original ideas and to pay more attention to peers’ ideas in online collaborative groups.     

Stimulators and barriers towards social innovations in public libraries: Qualitative research study

Public libraries have a huge potential to be creators and facilitators of social innovation in communities and society. Qualitative research based on interviews with 27 librarians showed that social innovation in libraries can take the form of educational and cultural activities, leisure and networking activities and social support services. The main goal of the research was to find out what factors support and make these innovations difficult in public libraries. A four-layer model of barriers and stimulators for social innovation is presented, which includes structural, local, organizational and personnel levels. The model could serve to inform librarians, their stakeholders and governments about all levels of barriers and stimulators connected to innovation of library services and social re-positioning of public libraries in the future.     

The Visual Holdings of the Slavonic Library,Prague

This study focuses on the visual collections in the holdings of the Slavonic Library (a section of the National Library of the Czech Republic). The library holdings also include unique collections relevant to the topic of Russian and Ukrainian emigration: collections of visual art, ex libris, posters and flyers by Ukrainian émigrés (1918–1945), and a collection of invitations and flyers by Russian émigrés (1918–1945). Rudolf H?lka’s collection of photographs, dating back to the 1920s, captures a series of ethnographic, folkloric, and architectonic phenomena which no longer exist. Moreover, Russian posters from the period of WWI, from the revolutionary year of 1917, and the subsequent civil war are equally fascinating as are banknotes from the same period and region.     

我国企业多角化战略与研发强度之间关系的实证研究--以浙江省为例

理论上,企业多角化战略类型的不同影响到了企业对不同内部控制制度的采纳,而不同的内部控制制度又使得部门经理形成不同的风险偏好倾向,并最终影响到了企业研发强度的高低。对此,本文以浙江民营企业为样本进行了实证研究,结果发现企业多角化战略类型与研发强度之间并不存在显著的相关性。     

The effect of inspiratory muscle fatigue on acid-base status and performance during race-paced middle-distance swimming

The aim of this study was to investigate the effect of pre-induced inspiratory muscle fatigue (IMF) on race-paced swimming and acid-base status. Twenty-one collegiate swimmers performed two discontinuous 400-m race-paced swims on separate days, with (IMF trial) and without (control trial) pre-induced IMF. Swimming characteristics, inspiratory and expiratory mouth pressures, and blood parameters were recorded. IMF and expiratory muscle fatigue (P < 0.05) were evident after both trials and swimming time was slower (P < 0.05) from 150-m following IMF inducement. Pre-induced IMF increased pH before the swim (P < 0.01) and reduced bicarbonate (P < 0.05) and the pressure of carbon dioxide (PCO₂) (P < 0.05). pH (P < 0.05), bicarbonate (P < 0.01) and PCO₂ (P < 0.05) were lower during swimming in the IMF trial. Blood lactate was similar before both trials (P > 0.05) but was higher (P < 0.01) in the IMF trial after swimming. Pre-induced IMF induced respiratory alkalosis, reduced bicarbonate buffering capacity and slowed swimming speed. Pre-induced and propulsion-induced IMF reflected metabolic acidosis arising from dual role breathing and propulsion muscle fatigue.
