Building a Virtual Campus: Librarians as Collaborators in Online Course Development and Learning

ABSTRACT

In 2001, the Saskatchewan Institute of Applied Science and Technology (SIAST) Libraries began an informal partnership with the college's online course development unit: the Virtual Campus. What initially began as a relationship based on the traditional reference model has continued to evolve. Librarians now act as integral team members in course design and delivery along with providing information literacy instruction. This article discusses the evolution of SIAST Libraries’ relationship with the Virtual Campus and presents a model of the collaboration that has taken place. In addition, it describes the ways in which this relationship has impacted the role of SIAST's librarians as well as improved communication with and services for off-campus students and faculty.     

Beyond the ‘classic’ nurture group model: an evaluation of part‐time and cross‐age nurture groups in a Scottish local authority

This study begins to explore ways in which the principles underpinning the traditional ‘nurture group’ model could be altered and age ranges extended while continuing to deliver the proven success of nurture groups in promoting children's social and emotional development. Part‐time nurture groups were established in four different primary schools within the same council area. A total of 25 pupils ranging from age four to ten years attended the nurture groups for the 2006/7 school session and a control group was established within each school. All fifty children were tested using the Boxall Profile, literacy, numeracy and motor skills baseline assessments at pre‐, mid‐ and post‐nurture group intervention. Analysis of the results showed that for the children who had received a part‐time nurture group experience, statistically significant gains were made in the areas of development assessed by the Boxall Profile. Gains were also made in the areas of literacy, numeracy and motor skills; however, these gains were not at a statistically significant level. Results also show that the younger the pupil accessed the nurture group, the more significant gains were made in the measures used.     

Inclusive Classroom Profile: a pilot study of its use as a professional development tool

Research has highlighted that children with Special Educational Needs (SEN) might be at risk of receiving less-than-outstanding experiences in settings typically rated as outstanding. There are still significant barriers to the implementation of high-quality inclusive practices in early years settings: inadequate preparation of early educators for implementing inclusive classroom practices, and a lack of reliable and valid measures for assessing the quality of inclusive practice. The Inclusive Classroom Profile (ICP) was designed to measure the quality of inclusive classroom practices that can support the developmental needs of children with SEN in early childhood programmes. This paper describes the first study that explored the feasibility and usefulness of the ICP measure for quality improvement. The usability of the ICP was explored in the context of a partnership between a team of early years inclusion advisors and inclusive settings in one local authority in south England. Early years advisors received training for using the ICP and performed follow-up feedback visits to settings. Advisors achieved reliability proficiency and rated the ICP measure and training programme positively. Future research needs to investigate how the ICP might support quality improvement through designing and piloting the effectiveness of a multi-component professional development programme.     

Different combinations of perceived autonomy support and control: identifying the most optimal motivating style

Background: According to Self-Determination Theory, teachers and sport coaches can differ in the motivating style they rely upon to motivate young people. When endorsing an autonomy-supportive motivating style, instructors try to identify, vitalize, and nurture youngsters’ inner motivational resources. In contrast, instructors with a dominant controlling motivating style rather pressure youngsters to think, feel, or behave in prescribed ways. While the dimensions of autonomy support and control can be conceptually differentiated, in reality both dimensions may co-occur to different degrees.

Purpose: The present study investigates to what extent perceived autonomy support and control can be combined and which motivating style then yields the most optimal pattern of outcomes.

Research design: Multi-Study with Cross-Sectional Design.

Findings: In two studies, conducted among elite athletes (N?=?202; M_age?=?15.63; SD?=?1.70) and students in physical education (N?=?647; M_age?=?13.27; SD?=?0.68) reporting on their instructor’s motivating style, cluster analyses systematically pointed towards the extraction of four motivating profiles. Two of these groups were characterized by the dominant presence of either autonomy support (i.e. high-autonomy support) or control (i.e. high control), while the two dimensions were found to be equally present in the two remaining groups (i.e. high–high or low–low). Results revealed that the high-autonomy support group showed to the most optimal pattern of outcomes (e.g. need satisfaction, autonomous motivation), while the high-control group yielded the least optimal pattern of outcomes. Results further showed that perceiving one’s instructor as high on control is detrimental (e.g. higher need frustration, amotivation) even when the instructor is additionally perceived to be autonomy-supportive. Finally, it appeared better to be relatively uninvolved than to be perceived as exclusively high on control.

Conclusions: When coaches or teachers are perceived to be high on autonomy support and low on control, this is likely to benefit youngsters’ motivation and well-being. Also, while some instructors, particularly those who are functioning in a more competitive context where pressure is considered more normative, may endorse the belief that the combination of autonomy support and control yields the most effective cocktail to motivate young people (e.g. using competitive and game-based activities to make it fun, while treating ‘the losers’ with punishments such as push-ups or humiliating comments), this perspective is not supported by the findings of the current study. Apart, from its theoretical relevance, the findings of the present study are valuable for future intervention development.     

47例甲状腺微小癌诊治分析

目的：探讨甲状腺微小癌的临床诊断和治疗方法。方法：对诊断明确的47例甲状腺微小癌进行回顾性分析。结果：术前仅12例疑为甲状腺癌．余35例均于术中冰冻和术后病理确诊。34例合并甲状腺良性疾病，伴颈淋巴结转移3例。47例中有11例术后无瘤生存时间≥10年，24例术后无瘤生存时间≥5年。结论：甲状腺微小癌术前不易确诊，且易漏诊，对甲状腺良性疾病手术时应仔细触诊，对可疑结节行冰冻切片。首次手术应行患侧腺叶及峡部切除术．有淋巴结转移者行功能性淋巴结清扫术可取得较好疗效。     

浅论服装廓形的设计

服装外轮廓原意是影像、剪影、侧影、轮廓，在服装设计上引申为外形、外廓线、大形、廓型等意思。服装外轮廓是一种单一的色彩形态，人眼在没有看清款式细节以前首先感觉到服装的外轮廓。服装廓型是服装整体外形。形状广泛，种类丰富。不同的服装廓型。预示着服装的流行趋势。在掌握其廓型设计元素的同时，对不同的廓型进行合理搭配组合，可提高服装的品质和竞争力。     

Model-based testing with UML applied to a roaming algorithm for Bluetooth devices

In late 2001,the Object Management Group issued a Request for Proposal to develop a testing profile for UML2.0. In June 2003,the work on the UML 2.0 Testing Profile was finally adopted by the OMG. Since March 2004,it has become an official standard of the OMG. The UML 2.0 Testing Profile provides support for UML based model-driven testing. This paper introduces a methodology on how to use the testing profile in order to modify and extend an existing UML design model for test issues. The application of the methodology will be explained by applying it to an existing UML Model for a Bluetooth device.     

A fast block-matching algorithm based on variable shape search

INTRODUCTION Block-matching motion estimation is a key video coding technology that reduces the temporal redundancy between adjacent frames. The 3GPP/ 3GPP2 mandatory video codecs (MPEG-4 Simple Profile or H.263 Baseline) have adopted this tech- nology extensively. However, block-matching motion estimation is quite computationally intensive if the Full Search (FS) algorithm is used which exhaus- tively checks all possible candidate motion vectors within the search window. Therefore…
