Role of knowledge and ability in student nurses` clinical decision-making

Little is known about the acquisition of decision-making skills in nursing students as a function of experience and academic ability. Knowing how experience and academic skills interact may help inform clinical education programs and formulate ways of assessing students' progress. The aims of the present study were to develop a problem-solving task capable of measuring clinical decision-making skills in novice nurses at different levels of domain-specific knowledge; and to establish the relative impact on decision-making of domain-specific knowledge and general ability as determinants of the acquisition of decision-making skills. Three types of clinical problems of increasing complexity were developed. Sixty second-year and third-year student nurses with high and low academic scores were studied in terms of their ability to generate hypotheses for a hypothetical case, recognize disconfirming information and the need to access additional information, and diagnostic accuracy. The results showed that general academic ability and knowledge function partly independently in the acquisition of expertise in nursing. Academic ability affects decision-making in low complexity tasks, but as case complexity increases, domain-specific knowledge and experience determines decision-making skills. There are important differences in the way novices with different levels of knowledge and ability make clinical decisions and these can be studied by systematically increasing the complexity of the decision task. These results have implications for the way in which clinical education is structured and evaluated.

Selection, exclusion and assimilation: the project lambert of 1931 on the reform of French immigration policy

The unemployment crisis of 1926-7 focused attention onto the question of immigration. Historians of this period have generally focused on the crisis of public policy and popular antipathies towards foreigners; more recently historians have become attuned to voices of racism. Less attention has been paid to attempts to redress the policy weaknesses through a new legislative regime on immigration. This paper reviews one such proposal, made by Charles Lambert, a deputy from the Rhone, in 1931. Instrumental in a revision of the naturalization law in 1927 to encourage the assimilation of foreigners through the acquisition of French citizenship, Lambert proposed a comprehensive statute on immigration to select “desirable” foreigners and exclude the “undesirables” to promote the assimilation of the “better” elements. The paper argues that his rationale betrays a profound fear of mounting French weakness in the face of economic and demographic decline, and grave anxieties for the future health of the French nation.

Assessment methods in social work education: a review of the literature

Student assessment is an important component of social work education, and consumes considerable effort on behalf of both students and staff members. Social work educators in higher education face the challenge of constructing assessment methods, which encourage the development of reflective and critical learning, as well as enabling students to demonstrate acquisition of required knowledge and/or skills. While there is now a substantial literature on field education, the assessment of classroom-based units has warranted less attention. This paper examines the range of assessment methods reported in the social work education literature, the evidence which supports the use of these methods and issues associated with the identified assessment methods.

The importance of IS stakeholder perspectives and perceptions to requirements negotiation

Project managers and developers need to acknowledge the influence of IS stakeholders’ perspectives and perceptions on the outcome of requirements negotiation - the essential component of requirements elicitation. This paper describes a conceptual study, which demonstrates such an influence and asserts that stakeholder perspectives, goals and issues are the key to negotiators’ perceptions of the system requirements. Analysis of two seminal IS case studies further supports this assertion and indicates that goals, perspectives and prior experience with negotiation techniques can guide stakeholders bargaining behaviour during requirements negotiation. Our findings also show that to achieve consensus on requirements, stakeholder perspectives must be aligned or accepted by negotiating parties. Achieving alignment of perspectives, however, is quite difficult because during requirements elicitation stakeholders’ goals continually alter due to their acquisition of technical and business knowledge, development of inter-personal relationships and creation of new perceptions of issues relevant to requirements negotiation.

Ontogeny of body size and shape of Antarctic and subantarctic fur seals

Pre- and post-weaning functional demands on body size and shape of mammals are often in conflict, especially in species where weaning involves a change of habitat. Compared with long lactations, brief lactations are expected to be associated with fast rates of development and attainment of adult traits. We describe allometry and growth for several morphological traits in two closely related fur seal species with large differences in lactation duration at a sympatric site. Longitudinal data were collected from Antarctic (Arctocephalus gazella (Peters, 1875); 120 d lactation) and subantarctic (Arctocephalus tropicalis (Gray, 1872); 300 d lactation) fur seals. Body mass was similar in neonates of both species, but A. gazella neonates were longer, less voluminous, and had larger foreflippers. The species were similar in rate of preweaning growth in body mass, but growth rates of linear variables were faster for A. gazella pups. Consequently, neonatal differences in body shape increased over lactation, and A. gazella pups approached adult body shape faster than did A. tropicalis pups. Our results indicate that preweaning growth is associated with significant changes in body shape, involving the acquisition of a longer, more slender body with larger foreflippers in A. gazella. These differences suggest that A. gazella pups are physically more mature at approximately 100 d of age (close to weaning age) than A. tropicalis pups of the same age

Fostering deep and elaborative learning and generic(soft) skill development: the strategic use of case studies in accounting education

It is vital that accounting educators take responsibility for the development of students' generic (soft) skills in conjunction with, discipline-specific skills. Research indicates that the typical learning styles of accounting students are not suited to the acquisition of generic skills. In this paper learning theory is used to provide a framework to support the use of case studies as a tool to promote appropriate learning styles and thereby enhance generic skill development. The paper details a number of strategies that may be implemented with case studies to achieve these goals. The implications for accounting educators, which are significant, are discussed.

Reuse of learning objects? why, how and when?

This paper describes the rationale behind the specification and acquisition of a Digital Objects Management System (DOMS) at Deakin University. Key drivers are: compliance with the provisions of the Digital Agenda Act for the communication of copyright works; improved management of Deakin’s intellectual property, and reduction in costs of delivering online content via a learning management system.

Details of the desired functionality and potential integration issues are addressed. During the specification stage, additional uses for a digital object management system were identified that relate to the broader notion of knowledge management, and these will be discussed.

At the time of writing, no decision has been made as to which vendor(s) will be successful in gaining the University’s contract for the management of digital learning objects.

Experience and experiential learning : perceptions of the diabetes educator role

A great deal of learning associated with specially nursing roles occurs informally and experientially. Here, the authors explore experience and experiential learning in the professional development of nurse diabetes educators. The role of experiential learning in the acquisition of diabetes education and management skills and the ways in which experiential learning can be quantified for the purposes of demonstrating professional competency, are discussed in the light of data collected from two questionnaires distributed to diabetes educators, and endocrinologists, and a series of focus groups.

The development of 'soft' strategic indicators for international client satisfaction

Despite the increasing significance of the construction industry as an emerging sector of the Australian economy, there is inadequate research performed on construction design firms in terms of theoretical and empirical foundations. Although past research has identified the barriers and success factors for firm market entry, evidence suggests that to date no research has explicitly explored the sustainability of construction design firms in international markets. SMEs and their approach to firm internationalisation differ significantly from large manufacturing firms and a vast majority of construction design firms operate as SMEs. This paper develops a sustainable business model for construction design SMEs, which rely upon the development of clear Client Following (CF) versus Market Seeking (MS) strategies to support internal firm strategic and operational management. The understanding of these strategies is vital as the application of either will shape the design management approach of firms, which would in turn impact on the sustainability of these firms in foreign markets. Long-term sustainability of firms in international markets relies heavily upon client satisfaction. Client and project team participants’ communication during various design processes has often been problematic and the added difficulty of communicating across international boundaries further compounds the problem of capturing and maintaining client’s requirements. Therefore this paper develops a model for business sustainability of Australian construction design firms working in international markets by exploring factors that affect client satisfaction across international boundaries, through the development of business performance indicators. These include not only the critical financial capital but also other ‘softer’ indicators, namely: social, cultural and intellectual capital. These act as a firm’s measure of success and the acquisition of this type of capital will provide significant advantages to firms’ success, hence sustainability in international markets.

Perceptions of generic skill development : international and local accounting students in Australia

In recent times, the growing emphasis on graduate outcomes has led to a consensus amongst educators, employers and other stakeholders that a better mix of technical and generic skills should be fostered in accounting students. Given the increased importance placed on generic skill acquisition, this study seeks to gain an understanding of undergraduate accounting students’ perceptions of the skills they feel they acquire during their studies. The increased diversity of the background of students studying accounting in Australia has also raised concerns about the acquisition of generic skills among various student cohorts. Using a case study of accounting students studying at an Australian university, a logistic regression model is applied to determine differences in perceptions of generic skill development between two student cohorts (local and international). The findings indicate that while both groups perceived their degree studies contributed to the development of generic skills, international students thought that their studies aided the development of generic skills more so than local students. Furthermore, it appears that some skills appear to be more successfully integrated into the curriculum than others.

Evaluating the impact of an environmental education programme; an empirical study in Mexico.

This study draws on information from 11 in-depth interviews, two focus groups and 72 written questionnaires to evaluate an extra-curricular environmental education programme on forestry designed for preparatory school students from a small rural community in Mexico. Specifically, the study assessed the impact of the programme on the ecological knowledge of 72 students. Qualitative feedback suggests that students learnt about forestry, acquired greater awareness of the importance of conservation for the local environment and enjoyed the participatory teaching methods used in the programme. Quantitative results show a positive and significant association between the number of times a student participated in the programme and the student’s ecological knowledge. Students who participated in the programme once had a 16.3% higher knowledge on ecological concepts and knew, on average, 1.5 more local forest plants than students who never attended it (p<.001). Findings suggest that the inclusion of participatory environmental education programmes in preparatory schools would improve the acquisition of ecological knowledge. Further research could consider the consistency of the findings by replicating participatory methods presented here and by using an experimental research design.

The roles of object-image relative motion and static depth information in the perception of heading

Investigates visual information that enables human to effectively guide their movement through the environment. This problem is fundamental to the study of human behaviour, since survival is contingent upon the acquisition of resources that lie in different locations throughout the environment.

Fundamental movement skills in children and adolescents : review of associated health benefits

The mastery of fundamental movement skills (FMS) has been purported as contributing to children's physical, cognitive and social development and is thought to provide the foundation for an active lifestyle. Commonly developed in childhood and subsequently refined into context- and sport-specific skills, they include locomotor (e.g. running and hopping), manipulative or object control (e.g. catching and throwing) and stability (e.g. balancing and twisting) skills. The rationale for promoting the development of FMS in childhood relies on the existence of evidence on the current or future benefits associated with the acquisition of FMS proficiency. The objective of this systematic review was to examine the relationship between FMS competency and potential health benefits in children and adolescents. Benefits were defined in terms of psychological, physiological and behavioural outcomes that can impact public health. A systematic search of six electronic databases (EMBASE, OVID MEDLINE, PsycINFO, PubMed, Scopus and SportDiscus) was conducted on 22 June 2009. Included studies were cross-sectional, longitudinal or experimental studies involving healthy children or adolescents (aged 3–18 years) that quantitatively analysed the relationship between FMS competency and potential benefits. The search identified 21 articles examining the relationship between FMS competency and eight potential benefits (i.e. global self-concept, perceived physical competence, cardio-respiratory fitness [CRF], muscular fitness, weight status, flexibility, physical activity and reduced sedentary behaviour). We found strong evidence for a positive association between FMS competency and physical activity in children and adolescents. There was also a positive relationship between FMS competency and CRF and an inverse association between FMS competency and weight status. Due to an inadequate number of studies, the relationship between FMS competency and the remaining benefits was classified as uncertain. More longitudinal and intervention research examining the relationship between FMS competency and potential psychological, physiological and behavioural outcomes in children and adolescents is recommended.

Identification of a by-product of nitric oxide synthase activity in human acute brain injury with in vivo proton magnetic resonance spectroscopy

BACKGROUND AND PURPOSE: Laboratory studies have been used to identify nitric oxide as a notable mediator in neuronal death after acute brain injury. To our knowledge, this has not previously been confirmed with in vivo study in humans. Our purpose was to seek in vivo evidence for the induction of nitric oxide synthase (NOS) in human acute brain injury by using proton MR spectroscopy.

METHODS: In vitro proton MR spectra were obtained in neural extracts from 30 human cadavers, and in vivo spectra were obtained in 20 patients with acute brain injury and in a similar number of control subjects.

RESULTS: We identified a unique peak at 3.15 ppm by using in vivo proton MR spectroscopy in eight of 20 patients with acute brain injury but not in 20 healthy volunteers (P < .002). On the basis of in vitro data, we have tentatively assigned this peak to citrulline, a NOS by-product.

CONCLUSION: To our knowledge, our findings suggest, for the first time, that excitotoxicity may occur in human acute brain injury. Confirmation with the acquisition of spectra in very early acute cerebral injury would provide a rationale for the use of neuroprotective agents in these conditions, as well as a new noninvasive method for quantification.

ATR FT-IR absorption enhancement of a thin film under the photon-tunneling condition

A simple, yet very powerful technique for the spectral acquisition of an extremely thin film with enhanced absorption was explored. An infrared absorption of an extremely thin film confined between media of high refractive indices was greater than that of its bulk when the spectrum was acquired under the attenuated total reflection (ATR) condition with parallel (p) polarized radiation. The absorption enhancement was not observed under perpendicular (s) polarized radiation. Theoretical investigations indicated that the absorption enhancement was proportional to the integration of the mean square evanescent field within the film. The field integration under p-polarized radiation increased, while that under s-polarized radiation decreased as the thickness of the confined film became thinner. The maximum enhancement was observed when the film was sufficiently thinner than the penetration depth. The phenomena were experimentally investigated, and the results agreed very well with theoretical predictions.
