The minimum moral content of law : a critique of Hart's descriptive theory of positive and natural law

Review of H.L.A. Hart's account of the minimum moral content of law - assesses its consistency with the methodology provided in his description of the focal meaning or central case of law - particular focus is Hart's consideration of the ultimate end of man - how difficulties faced by Hart's account of the minimum moral content of law can be overcome.

Organisational transformation through CRM implementation: a descriptive case study

CRM is becoming critical to organisations worldwide as global competition increases and technological innovations in communication continue to emerge. In this descriptive case study, we have investigated a utility provider – with a geographical monopoly, who has successfully implemented a complaint management system, as part of their CRM process transformation. We have applied the teleological process theory (Ven de Ven and Poole 1995) to describe the organisational change, based on our empirical research.

A cross-continental examination and comparison of descriptive criteria in marketing journals-AMJ, EJM and JM

The objective is to perform a cross-continental examination and comparison of non-traditional descriptive criteria in a selection of leading academic journals in marketing. The sample of journals is restricted to the examination and comparison of three academic journals in marketing. The journal sample consists of the Australasian Marketing Journal (AMJ), the European Journal of Marketing (EJM) and the Journal of Marketing (JM). Empirical research manuscripts dominate in the selected marketing journals. In addition, in the selected journals regular issues dominate in favour of special issues. The descriptive criteria examined and compared in AMJ, EJM and JM are based upon the content analysis of 811 manuscripts published during a six-year period, namely 2000-2005. Manuscripts of types other than empirical research, such as general reviews, literature reviews, conceptual papers, commentaries and book reviews are less likely to get published. Special issues or special sections are less frequent in these journals. This may lead to the situation that specialized journals in sub-areas of marketing may provide better and more comprehensive leading edge coverage and knowledge. The insights provided are in particular valuable for those scholars that do not usually get involved in academic publishing and consequently have a limited understanding and experience of the publication arena of manuscripts in leading academic journals. These insights also will be informative for more experienced academic publishers as they highlight certain characteristics of these journals that enlighten one as to the journals that one should target for publication and the difficulty, just on a numbers basis alone, of getting published in one of these three journals. The principal contribution of this research is the examination and comparison of descriptive criteria in AMJ, EJM and JM – a cross-continental sample of journals and criteria that have not been explored or reported previously in literature.

Making decisions for intelligent agents in procedure descriptive framework

There are many existing and potential industrial and commercial applications for intelligent agents in the literature. The very challenging issue for these applications is to "do what intelligent agents should do". The BDI (beliefs, desires, intentions) architecture is presented to solve this challenge, and it has attracted much attention. The main difficulty for this architecture is the formalization problem. In this paper, we discuss the "procedure descriptive framework", which is a method for formalizing the BDI architecture. We present decision models for intelligent agents in this framework. This research provides a technique for online agents to form beliefs and make decisions according to the current uncertain environment

Brief report : The defense mechanisms of homophobic adolescent males : a descriptive discriminant analysis

The study examined the role of defense mechanisms in homophobic attitudes of older male adolescents aged 17e18 years. A cross-sectional survey collected data from final year high school students (N ¼ 86) attending an all male school in a regional centre in Victoria, Australia. The school was identified by teachers as having a problematic culture of homophobic intolerance. Participants were divided into homophobic and non-homophobic groups based on their scores on the Homophobia Scale Questionnaire. Discriminant analysis was conducted to identify the predictors that would best categorise students into those two groups on the basis of defense styles derived from the Defense Style Questionnaire-40 (DSQ-40). The strongest predictors of homophobia amongst defense styles were idealisation, denial, somatisation and devaluation accounting for 18.31%, 17.64%, 13.10% and 11.35% of the variance, respectively. Results generally supported the larger contribution of more immature defenses to higher levels of homophobia.

A descriptive model for the formation of ultrafine grained steels

This paper presents a descriptive model to explain the mechanisms involved in the development of ultrafine grained structure in steels through dynamic strain induced transformation. The model considers the microstructural evolution during and after deformation as well as the role of different process variables. A key factor is the competition between nucleation and growth, where it is shown that many potential nuclei can be lost under certain conditions leading to a mixed or coarser grain size.

The descriptive and explanatory nature of chemical diagrams does not guarantee understanding

Volunteer non-major chemistry students, taking an introductory university chemistry course (n= 17) were interviewed about their understanding of a variety of chemical diagrams. All the students’ interviewed appreciated that diagrams of laboratory equipment were useful to show how to set up laboratory equipment. However students’ ability to explain specific diagrams at either the macroscopic or sub-microscopic level varied greatly. The results highlighted the poor level of understanding that some students had even after completing both exercises and experiments using the diagrams. The connection between the diagrams of the macroscopic level (equipment), the sub-microscopic level (molecular) and the symbolic level (equations) was not always apparent to students. The results indicate a need for chemical diagrams to be used carefully and more explicitly to ensure the learner understanding.

Tracheostomy decannulation failure rate following critical illness : a prospective descriptive study

Background : Tracheostomy is a well established and practical approach to airway management for patients requiring extended periods of mechanical ventilation or airway protection. Little evidence is available to guide the process of weaning and optimal timing of tracheostomy tube removal. Thus, decannulation decisions are based on clinical judgement. The aim of this study was to describe decannulation practice and failure rates in patients with tracheostomy following critical illness.

Methods : A prospective descriptive study was conducted of consecutive patients who received a tracheostomy at a tertiary metropolitan public hospital intensive care unit (ICU) between March 2002 and December 2006. Data were analysed using descriptive and inferential tests.

Results : Of the 823 decannulation decisions, there were 40 episodes of failed decannulation, a failure rate of 4.8%. These 40 episodes occurred in 35 patients: 31 patients failed once, 3 patients failed twice and 1 patient failed three times. There was no associated mortality. Simple stoma recannulation was required in 25 episodes, with none of these patients readmitted to ICU. Translaryngeal intubation and readmission to ICU took place for the remaining 15 episodes. The primary reason for decannulation failure was sputum retention. Twenty-four patients (60%) failed decannulation within 24 h, with 14 of these occurring within 4 h.

Conclusions : Clinical assessments coupled with professional judgement to decide the optimal time to remove tracheostomy tubes in patients following critical illness resulted in a failure rate comparable with published data. Although reintubation and readmission to ICU was required in just over one third of failed decannulation episodes, there was no associated mortality or other significant adverse events. Our data suggest nurses need to exercise high levels of clinical vigilance during the first 24 h following decannulation, particularly the first 4 h to detect early signs of respiratory compromise to avoid adverse outcomes.

Content-based video indexing for sports applications using integrated multi-modal approach

This thesis presents a research work based on an integrated multi-modal approach for sports video indexing and retrieval. By combining specific features extractable from multiple (audio-visual) modalities, generic structure and specific events can be detected and classified. During browsing and retrieval, users will benefit from the integration of high-level semantic and some descriptive mid-level features such as whistle and close-up view of player(s). The main objective is to contribute to the three major components of sports video indexing systems. The first component is a set of powerful techniques to extract audio-visual features and semantic contents automatically. The main purposes are to reduce manual annotations and to summarize the lengthy contents into a compact, meaningful and more enjoyable presentation. The second component is an expressive and flexible indexing technique that supports gradual index construction. Indexing scheme is essential to determine the methods by which users can access a video database. The third and last component is a query language that can generate dynamic video summaries for smart browsing and support user-oriented retrievals.

Descriptive epidemiology of Australian football injuries presenting to sports medicine clinics

Sports injury prevention has been the focus of a number of recent public health initiatives due to the acknowledgement that sports injuries are a significant public health problem in Australia Whilst Australian football is one of the most popular participation sports in the country, only very limited data is available about football injuries The majority of sports injury data available for this sport is from hospital emergency departments and elite-level injury surveillance Overall there is a paucity of data from treatment settings other than hospitals In particular, there is a lack of information about the injuries sustained by community-level, junior and recreational Australian football participants. One good potential source of football injury data is sports medicine clinics. Analysis of injury presentations to sports medicine clinics was undertaken to provide a detailed description of the epidemiology of Australian football injuries that present to this treatment setting and to determine the implications for injury prevention in this sport. In addition, the data from sports medicine clinics was compared with existing sources of Australian football injury data to determine how representative sports medicine clinic data is of other football injury data sources and to provide recommendations for future injury surveillance n Australian football. The results contained in this thesis show that Australian football is the sport most associated with injury presentation at sports medicine clinics. The majority of injured Australian football players presenting to sports medicine clinics are community-level or junior participants which suggests that sports medicine clinics are a good source of information on the injuries sustained by sub-elite football participants. Competition is the most common context in which Australian football players presenting to sports medicine clinics are injured. The major causes of injuries to Australian football players are being struck by another player, collisions and overuse. Injuries to Australian football players predominantly involve the lower limb. Adult players, players who stopped participating immediately after noticing their injury and players with overuse injuries are the most likely to sustain a more severe injury (i.e. more than four weeks before a full return to football participation and a moderate/significant amount of treatment expected). The least experienced players (five or less years of participation) are more likely to require a significant amount of treatment than the more experienced players. The prevention of lower limb injuries, injuries caused by body contact and injuries caused by overuse should be a priority for injury prevention research in Australian football due to the predominance of these injury types in the pattern of Australian football injuries Additionally, adult players, as a group, should be a focus of injury prevention activities in Australian football due to the association between age and injury severity. Overall, the pattern of Australian football injuries presenting to sports medicine clinics appears to be different than reported by club-based and hospital emergency department injury surveillance activities. However, detailed comparison of sports medicine clinic Australian football data with other sources of Australian football injury data is difficult due to the variable methods of collecting and reporting injury information used by hospital emergency department and club-based injury surveillance activities. The development of a standardised method for collecting and reporting injury data in Australian football is strongly recommended to overcome the existing limitations of data collection in this sport. In summary, sports medicine clinics provide a rich source of Australian football injury data, especially from the community and junior levels of participation. The inclusion of sports medicine clinic data provides a broader epidemiological picture of Australian football injuries. This broader understanding of the pattern of Australian football injuries provides a better basis for the development of injury prevention measures in this sport.

Descriptive and prescriptive analyses of aid allocation : approaches, issues and consequences

Studies of the interrecipient allocation of aid may be categorized threefold. First, there are those that attempt to explain the observed allocation of aid. Second, there are those that seek to describe or evaluate the allocation of aid against normative criteria. Third, there are those that seek to prescribe the interrecipient allocation of aid by calculating the amounts of aid each country should receive, also based on normative criteria. This article looks at the second and third categories of studies. It commences by looking at the different approaches and a descriptive measure used, and then repeats this exercise for the prescriptive literature. It then looks at differences between the prescribed allocations of the different approaches used in the literature. These allocations are then compared with actual allocations and evaluated against various normative criteria. This reveals significant differences, both between prescribed and actual allocations and the evaluations of the different prescriptive approaches.
