Age estimation by measurements of developing teeth: accuracy of Cameriere's method on a Brazilian sample

Developing teeth are commonly the criteria used for age estimation in children and young adults. The method developed by Cameriere et al. (Int J Legal Med 2006;120:49-52) is based on measures of teeth with open apex, and application of a formula, to estimate chronological age of children. The present study evaluated a sample of panoramic radiographs from Brazilian children from 5 to 15 years of age, to evaluate the accuracy of the method proposed by Cameriere et al. The results has proven the system reliable for age estimation, with a median residual error of -0.014 years between chronological and estimated ages (p = 0.603). There was a slight tendency to overestimate the ages of 5-10 years and underestimate the ages of 11-15 years.     

Searchers vs surveyors in estimating the monetary value of a QALY: resolving a nasty dilemma for NICE

Recently, for many health economics researchers, empirical estimation of the monetary valuation of a quality-adjusted life year (QALY) has become an important endeavour. Different philosophical and practical approaches to this have emerged. On the one hand, there is a view that, with health-care budgets set centrally, decision-making bodies within the system can iterate, from observation of a series of previous decisions, towards the value of a QALY, thus searching for such a value. Alternatively, and more consistent with the approach taken in other public sectors, individual members of the public are surveyed with the aim of directly eliciting a preference-based - also known as a willingness-to-pay-based (WTP-based) - value of a QALY. While the former is based on supply-side factors and the latter on demand, both in fact suffer from informational deficiencies. Sole reliance on either would necessitate an acceptance or accommodation of chronic inefficiencies in health-care resource allocation. On the basis of this observation, this paper makes the case that in order to approach optimal decision making in health-care provision, a framework incorporating and thus, to a degree, reconciling these two approaches is to be preferred.     

Psychosocial correlates of recidivism in a sample of ex-prisoners: the role of oppositional defiant disorder and conduct disorder

The present study aimed to (a) examine the role of Oppositional defiant disorder (ODD) and Conduct disorder (CD) in predicting recidivism, while controlling for childhood arrest, perceived neighbourhood crime frequency, alcohol consumption, age and gender, and (b) explore the relevance of these factors in predicting risk of recidivism for males and females separately. Participants were 669 ex-prisoners identified in the National Survey of American Life. Results revealed that gender, CD and average daily alcohol consumption predicted recidivism. When separate models were estimated for males and females, only average daily alcohol consumption was predictive of female recidivism. By comparison, recidivism was significantly predicted in males by CD in youth and childhood arrest. ODD was also negatively associated with recidivism in males. Consequently, targeting variables identified as significant predictors of recidivism for both males and females, or males, is unlikely to be an optimal way of reducing repeat offending.     

Online crisis communication response: A case study of fraudulent banking transactions in South Africa

Abstract

The emergence and advancement of information technology – specifically the replacement of face-toface services with innovative self-service technology, such as banking transactions on the Internet – is forcing companies to adopt a proactive approach to online crisis communication response, and to combine the management and control of online messages during a crisis. In the financial services industry, deregulation and the rapid growth in technology have removed entry barriers in the online environment, forcing financial institutions to transform from the traditional brick-and-mortar to click-and-mortar service delivery, while at the same time allaying customers’ fears (and the perceived risk) of fraudulent online transactions. Although studies have been conducted on the adoption, use, perceived risk and purchase intention of self-service technology, limited research has examined the knowledge management of an online crisis communication response. Knowledge management, which focuses on the acquisition, transfer and assimilation of information, is one way in which to manage messages effectively before, during and after an online crisis communication response situation. The main aim of this article is to identify and characterise typologies of the management and control of messages in an online crisis communication response, through an interpretative and critical analysis of fraudulent websites, based on the main premises of the knowledge management approach. This is done through a case study approach: the website of one of the top ten banks in South Africa was studied in terms of it dealt with fraudulent banking transactions, specifically from the knowledge management paradigm.     

Measuring knowledge management in a virtual chat room: A case study

Abstract

Many organisations deem the virtual workplace to be a solution to challenges such as global competition, accelerated product development, improved quality and customer service, to mention but a few. In spite of the success of virtual communities on the Internet and although a significant amount of research has been conducted on virtual organisations, very few studies have focused on the evaluation of the combined effects of the theoretical variables of knowledge management in virtual communities. Advanced web analytics have been used in some instances to test the content of virtual communities, like discussion forums, hat rooms and the like. Because a plethora of chat rooms are devoted to special interest topics that may implicitly contain information and insights on consumers, knowledge creation and sharing, it creates the ideal opportunity to measure the management of knowledge therein. The aim of this article is, therefore, to measure knowledge management in a virtual community (an online chat room of an academic institution). Firstly, the article propounds a brief overview of the theoretical underpinning of the study by proposing a conceptual framework for the measurement of knowledge management in virtual communities. Secondly, the methodology to measure the knowledge management in a chat room of an educational institution is outlined. Finally, the research results are presented and recommendations are made for future research.     

An integrated crisis communication framework for strategic crisis communication with the media: A case study on a financial services provider

Abstract

In order for organisations to survive in an ever-changing milieu in the current business environment, sufficient crisis communication and management practices need to be in place. Despite this, organisational crises are often inefficiently managed, which could be ascribed to the lack of strategic management of crises (Kash & Darling 1998: 180). This article explores the lack of strategic crisis communication processes to ensure effective crisis communication with the media as stakeholder group. It is based on the premise that the media are one of the main influencers of public opinion (Pollard & Hotho 2006: 725), thereby necessitating the need for the accurate distribution of information. Furthermore, the study focuses specifically on the financial industry, which is arguably more sensitive and thus more prone to media reporting because financial services providers manage people's money (Squier 2009). A strategic crisis communication process with the media is therefore proposed, facilitated through an integrated crisis communication framework, proposing a combination of integrated communication (IC) literature, with emphasis on Grunig's theory of communication excellence, to build sustainable media relationships through two-way communication; and a crisis communication process that has proactive, reactive and post-evaluative crisis communication stages, thereby moving away from seeing crisis communication as a predominantly reactive function.     

Towards a new model to describe the organisation–stakeholder relationship-building process: A strategic corporate communication perspective

Abstract

Successful organisations depend on stakeholder perceptions to address changes in turbulent organisational environments, report on the social and environmental impact of activities, the prevalence of public activism, globalisation, emerging issues and crises, and the need to be good corporate citizens through ethical and socially responsible behaviour. Despite the current emphasis on stakeholder relations and management, a lack of research exists on how to build these relationships. This article aims to report and discuss the findings of a study that explored the lack of organisation–stakeholder relationship (OSR) building models, to emphasise the elements and development of an OSR and highlight the need for a generic, strategic, integrated approach for sustainable OSR to contribute towards organisational effectiveness. This will be done using an exploratory literature review to constitute a conceptual framework for OSR building, of which the principles of the framework will be measured among leading Johannesburg Stock Exchange-listed South African organisations, by means of a quantitative web-based survey and qualitative one-on-one interviews. The dominant focus on organisational stakeholders has provided added impetus and importance to the role of corporate communication, hence, this article will simultaneously endeavour to highlight the importance of practising corporate communication strategically, by emphasising its role in OSR.     

Do Online Election Campaigns Win Votes? The 2007 Australian “YouTube” Election

Studies of Web use during elections have focused mainly on the content of Web sites and on the major factors driving parties' and candidates' adoption of the technology. Evaluations of the electoral impact of Web campaigns have been more limited. This article examines the nature and extent of Web use by voters and parties in the 2007 Australian federal election, focusing particularly on the consequences of Web 2.0 campaigning for candidate vote share. The findings show differing levels of commitment to older and newer e-campaigning technology across parties and their supporters and significant electoral advantages are associated with minor parties candidates using Web 2.0 campaign tools. The results confirm existing studies' findings about the impact of Web campaigns on contemporary elections, but that these effects are moderated by the type of Web tools used and party using them.     

Liberalisation and Seigniorage revenue in Kenya,Ghana and Tanzania

To inform policy, our study identifies which populations of AIDS-affected children are in need of educational assistance. Using the 2004–2005 Malawi Integrated Household Survey, multilevel models examine the association between AIDS-related impacts and educational outcomes. Double and maternal orphans are more likely to be out of school and behind in grade level; living with an adult suffering from a potential AIDS-related illness is also associated with disadvantage. These disparities are not explained by poverty status. Where both poverty and AIDS are endemic, both traditional development aid and orphan-specific programming are essential for equitable access to education.     

Constraints or Complaints? Business Climate and Firm Performance Perceptions in Uganda

This paper identifies the business constraints that are most binding for firm performance. Using panel methods on novel quarterly Ugandan business climate data, we exploit perceived changes in business climate constraints to account for changes in firm performance. Not all identified constraints are binding for firm performance. Macroeconomic instability, demand stability, access to finance, corruption/bribery, and weather variability are found to be binding constraints. Firms’ expectations about future performance outcomes are associated with current perceptions about these constraints, alleviating endogeneity concerns to some extent. While taxation constraints are usually highly ranked, we do not find evidence linking them to firm performance.
