以钝顶螺旋藻为载体,以硒浓度、锌浓度和添加方法为因素,通过单因素和正交试验,确定富锌、富硒钝顶螺旋藻的最佳培养条件.结果表明:在钝顶螺旋藻培养液中加入硒浓度为8 ug/mL、锌浓度为7 ug/mL,加入方法为低水平培养4天(加入浓度的一半)、高水平培养4天(加入剩余一半),为富锌、富硒钝顶螺旋藻的最佳添加浓度和添加方法.     

Fine Motor Control is Related to Cognitive Control in Adolescents with Down Syndrome

The connection between human cognitive development and motor functioning has been systematically examined in many typical and atypical populations; however, only a few studies focus on people with Down syndrome (DS). Twelve adolescents with DS participated and their cognitive control, measured by the Corsi-Block tapping test (e.g., visual working memory), the Auditory Memory span test (e.g., verbal working memory) and the Tower of London test (e.g., cognitive planning), and motor control, measured by the Purdue Pegboard (e.g., fine motor control), were measured in this study. Results indicate that if people with DS have better performance in fine manual dexterity, they will have better performance in cognitive planning and verbal working memory abilities. The co-activation hypothesis of the prefrontal area and the cerebellum may support this positive relationship. Hence, it is suggested people with DS will obtain benefits in cognitive control by participating in further motor intervention.     

Supporting pre-service teachers to enhance the effectiveness of their classroom practice through engaging with the ‘voice’ of their pupils

The research reported here was focussed on accessing the perceptions of pre-service teachers regarding the critical factors which support highly effective learning in schools in the United Kingdom. Their perceptions were arranged into a taxonomy so that they can be used as a starting point for their reflections on the observations they make of teaching and learning in schools with the aim of enhancing the effectiveness of their own teaching. The choice of technique used to access the perceptions was driven by the desire to provide the pre-service teachers with a method that they could use themselves to engage with the ‘voice’ of their own pupils regarding the factors which support effective learning. The engagement of pupil voice has become increasingly significant in understanding effective pedagogy and in securing more personalised approaches to learning in United Kingdom school contexts.     

Measuring cognitive load and cognition: metrics for technology-enhanced learning

This critical and reflective literature review examines international research published over the last decade to summarise the different kinds of measures that have been used to explore cognitive load and critiques the strengths and limitations of those focussed on the development of direct empirical approaches. Over the last 40?years, cognitive load theory has become established as one of the most successful and influential theoretical explanations of cognitive processing during learning. Despite this success, attempts to obtain direct objective measures of the theory's central theoretical construct – cognitive load – have proved elusive. This obstacle represents the most significant outstanding challenge for successfully embedding the theoretical and experimental work on cognitive load in empirical data from authentic learning situations. Progress to date on the theoretical and practical approaches to cognitive load are discussed along with the influences of individual differences on cognitive load in order to assess the prospects for the development and application of direct empirical measures of cognitive load especially in technology-rich contexts.     

Motivational factors in discussing sexual health with young people with chronic conditions or disabilities

The objective of this study was to identify determinants of professionals’ intention to use the new board game SeCZ TaLK to facilitate sexual health discussions with young people with chronic health conditions and disabilities, and to gauge whether intention led to actual use. A cross-sectional web-based survey of 336 professionals before they received the game sought to measure their intention to use SeCZ TaLK, their attitudes towards discussing sexuality, social professional environment, self-efficacy, opinion on the feasibility of using the game and experience discussing sexuality. Actual use of SeCZ TaLK was assessed at follow-up (N = 105). Professionals with higher self-efficacy and more experience in discussing sexual health were more likely to intend to use the game. At follow-up, intention to use explained 21% of the variance in actual use. SeCZ TaLK fits easily into the daily practice of professionals working in assisted-living and day-care facilities; other professionals experienced greater difficulty integrating the game into their practice. Despite this, SeCZ TaLk was also used across a wide range of settings including in psycho-educational groups, group consultations in hospitals and group therapy in rehabilitation centres. Professionals appreciated the board game SeCZ TaLK, but actual use depended on their own motivation and skills and compatibility with work routines.
