Analysis of construction dispute review boards

This paper presents the results of a research project undertaken to assess the impact of DRBs on the construction program of a large scale highway agency. Three dimensions of DRB impact were assessed: (1)influence on project cost and schedule performance, (2) effectiveness of DRBs in preventing and resolving construction disputes, and (3) costs of DRB implementation. The analyses encompass data from approximately 3,000 projects extending over a 10 year period (2000-2009).

No child’s play: Recognising the agency of former child soldiers in peace building processes

Engaging with the emerging discourse on children that recognises childhood as culturally specific and that children actively engage with their environment, this paper questions the dominant discourse’s view of children as passive recipients of socialisation. This paper argues that the discourse on children’s agency is a more useful framework for understanding the experiences of former child soldiers and that engaging meaningfully with this discourse will both improve life outcomes and reduce the risk of ongoing instability. This argument is made by an examination of the two discourses; examining their development and arguing for the usefulness of the agency discourse. This provides for an examination of children’s agency in education and skills training programs and of their political involvement (or marginalisation) in three conflicts: Colombia, Sierra Leone and Uganda. Recognising children as agents and engaging with how they navigate their lived experiences after involvement in conflict testifies to children’s resilience and their desire for change. Challenging the dominant discourse through the agency discourse allows for the acknowledgement of former child soldiers as both social and political agents in their own right and of their potential for contributing to stable and lasting peace.

Public private partnership infrastructure delivery: Benefits and costs for society

This research provides additional knowledge on the benefits and costs to society, in particular of road transport procured through Public-Private Partnership (PPP) arrangements. Currently, the public sector comparator (PSC) and cost-benefit analysis (CBA) used to evaluate and measure the benefits and costs of PPP are limited in their capacity to predict and forecast long-term events. PPP is attractive to governments due to the non-upfront payment, perceived value for money, and risk allocation and transfer to the private investor. However, public sector remains the guarantor, and under-writer of the private investor's loan from financial institutions and other voluntary risks which are unlimited to future compensatory claims. The new knowledge from this research is the introduction of a framework capable of evaluating, and measuring the associated PPP benefits, as well as the costs, effects, and impacts to society which are protracted and sporadic by nature.

Hospital infection control units: Staffing, costs, and priorities

Background: This article describes infection prevention and control professionals’ (ICPs’) staffing levels, patient outcomes, and costs associated with the provision of infection prevention and control services in Australian hospitals. A secondary objective was to determine the priorities for infection control units. Methods: A cross-sectional study design was used. Infection control units in Australian public and private hospitals completed a Web-based anonymous survey. Data collected included details about the respondent; hospital demographics; details and services of the infection control unit; and a description of infection prevention and control-related outputs, patient outcomes, and infection control priorities. Results: Forty-nine surveys were undertaken, accounting for 152 Australian hospitals. The mean number of ICPs was 0.66 per 100 overnight beds (95% confidence interval, 0.55-0.77). Privately funded hospitals have significantly fewer ICPs per 100 overnight beds compared with publicly funded hospitals (P < .01). Staffing costs for nursing staff in infection control units in this study totaled $16,364,392 (mean, $380,566). Infection control units managing smaller hospitals (<270 beds) identified the need for increased access to infectious diseases or microbiology support. Conclusion: This study provides valuable information to support future decisions by funders, hospital administrators, and ICPs on service delivery models for infection prevention and control. Further, it is the first to provide estimates of the resourcing and cost of staffing infection control in hospitals at a national level. Copyright

A theoretical framework for reducing tendering costs in the procurement of infrastructure projects

Purpose of this paper One way in which the tendering process can be further improved is by reviewing and clarifying the high costs that participants face during the course of the tendering phase. The study aims to provide project teams working in construction tender preparation a clear picture of what to expect when tendering for infrastructure projects. Design/methodology/approach Firstly, a review of current literature on tendering in infrastructure projects is conducted to identify the associated costs affecting traditional and PPP procurements as well as the potential measures contributing to tendering cost-reduction. A theoretical framework and its corresponding research hypotheses, which are based on the literature reviewed, are then proposed. An industry-wide questionnaire survey is currently under design to solicit industry practitioners’ views on tendering costs and the associated tendering cost-reduction measures. The data collected in the survey will subject to statistical analysis to test the proposed research hypotheses, which will be reported in a forthcoming paper. Findings and value The direct and indirect costs in public-private procurement have been identified and have been categorised into internal and external costs arising from working on tender submissions. A theoretical framework, mainly composed of five mechanisms of cost reduction, has been proposed and will be tested in a forthcoming industry-wide questionnaire survey. Originality/value of paper The findings are expected to lead to a transparent tendering process in infrastructure procurement, in which there is increased engagement from the private sector as well as an increase in competitive tendering.

Receivers' future liability for costs

In Juniper Property Holdings No.15 Pty Ltd v Caltabiano [2015] QSC 95, Jackson J considered what he described as a 'novel point' as to whether the court had jurisdiction to make a determination of the liability of receivers and managers appointed to the plaintiff to pay any costs orders that may be made in favour of the defendant.

Costs assessor selection: A question of timing, or cost?

In Lessbrook Pty Ltd (in liq) v Whap; Stephen; Bowie; Kepa & Kepa [2014] QCA 63 the Queensland Court of Appeal dealt with significant questions of general application relating to the appointment of assessors to conduct an assessment of costs under the Uniform Civil Procedure Rules 1999 (Qld) (UCPR).

Projecting excess emergency department visits and associated costs in Brisbane, Australia, under population growth and climate change scenarios

The direct and indirect health effects of increasingly warmer temperatures are likely to further burden the already overcrowded hospital emergency departments (EDs). Using current trends and estimates in conjunction with future population growth and climate change scenarios, we show that the increased number of hot days in the future can have a considerable impact on EDs, adding to their workload and costs. The excess number of visits in 2030 is projected to range between 98–336 and 42–127 for younger and older groups, respectively. The excess costs in 2012–13 prices are estimated to range between AU$51,000–184,000 (0–64) and AU$27,000–84,000 (65+). By 2060, these estimates will increase to 229–2300 and 145–1188 at a cost of between AU$120,000–1,200,000 and AU$96,000–786,000 for the respective age groups. Improvements in climate change mitigation and adaptation measures are likely to generate synergistic health co-benefits and reduce the impact on frontline health services.

An enquiry into the professional competence of inclusive education teachers in Beijing: Attitudes, knowledge, skills, and agency

Attitudes, knowledge, and skills are widely recognised as the three pillars of professional competence of inclusive education teachers. Studies emerging from the Chinese context consider these three pillars important for the practice of Learning in Regular Classrooms—an idiosyncratic Chinese form of inclusive education. Our mixed methods study reveals that agency is the fourth pillar of the professional competence for inclusive education teachers in Beijing, China. Results from comparative analysis indicate that the level of teachers’ agency is significantly lower than that of their attitudes, knowledge, and skills. We offer some implications for policy and practice in inclusive education.

A CCG virtual system for big data application communication costs analysis

Network topology and routing are two important factors in determining the communication costs of big data applications at large scale. As for a given Cluster, Cloud, or Grid system, the network topology is fixed and static or dynamic routing protocols are preinstalled to direct the network traffic. Users cannot change them once the system is deployed. Hence, it is hard for application developers to identify the optimal network topology and routing algorithm for their applications with distinct communication patterns. In this study, we design a CCG virtual system (CCGVS), which first uses container-based virtualization to allow users to create a farm of lightweight virtual machines on a single host. Then, it uses software-defined networking (SDN) technique to control the network traffic among these virtual machines. Users can change the network topology and control the network traffic programmingly, thereby enabling application developers to evaluate their applications on the same system with different network topologies and routing algorithms. The preliminary experimental results through both synthetic big data programs and NPB benchmarks have shown that CCGVS can represent application performance variations caused by network topology and routing algorithm.

Communicating consequences with costs: A commentary on Corso et al's cost of injury

Estimating the economic burden of injuries is important for setting priorities, allocating scarce health resources and planning cost-effective prevention activities. As a metric of burden, costs account for multiple injury consequences—death, severity, disability, body region, nature of injury—in a single unit of measurement. In a 1989 landmark report to the US Congress, Rice et al1 estimated the lifetime costs of injuries in the USA in 1985. By 2000, the epidemiology and burden of injuries had changed enough that the US Congress mandated an update, resulting in a book on the incidence and economic burden of injury in the USA.2 To make these findings more accessible to the larger realm of scientists and practitioners and to provide a template for conducting the same economic burden analyses in other countries and settings, a summary3 was published in Injury Prevention. Corso et al reported that, between 1985 and 2000, injury rates declined roughly 15%. The estimated lifetime cost of these injuries declined 20%, totalling US$406 billion, including US$80 billion in medical costs and US$326 billion in lost productivity. While incidence reflects problem size, the relative burden of injury is better expressed using costs.

Women and their Agency in the Neo-Assyrian Empire

Tämä pro gradu-työ käsittelee naisten toimijuutta uusassyrialaisessa imperiumissa. Toisin sanoen työssä tutkitaan naisten vaikutusmahdollisuuksia assyrialaisessa, patriarkaalisessa yhteiskunnassa – aihe, johon ei aiemmin ole juurikaan kiinnitetty huomiota. Täydennän työssä assyriologista näkökantaa kulttuuritieteiden ja antropologian käsitteistöllä ja teorioilla. Työn teoreettinen viitekehys liittyy yksilön, yhteiskunnan ja vallan välisiin suhteisiin, jotka kohtaavat toimijuuden käsitteessä. Vaikka työssä esittelen toimijuuden käsitettä laajemminkin, päädyin aineiston asettamien rajoitusten takia määrittelemään toimijuuden seuraavasti: toimijoita ovat ne naiset, jotka toimivat aktiivisina subjekteina yhteiskunnassa. Näin määritellyt toimijat jaoin vielä kahteen ryhmään, eksplisiittisiin (explicit agents) ja implisiittisiin (implicit agents) toimijoihin. Ensimmäisen ryhmän jäsenet selkeästi toimivat teksteissä jollain tavalla, jälkimmäisen ryhmän jäsenten toimijuus on pääteltävä asiayhteydestä. Pro graduni perustuu laajan tekstiaineiston analyysiin. Jaan imperiumin toimijanaiset kolmeen laajaan ryhmään: palatsissa, temppelissä ja niiden ulkopuolella toimineisiin naisiin. Jokaisen näistä kolmesta ryhmästä jaan vielä useisiin alaryhmiin, useimmiten ammattinimikkeen tai arvonimen mukaan. Suurimmaksi ryhmäksi osoittautuivat palatsissa toimineet naiset. Heistä erityisen aktiivisia olivat šakintut, jotka hoitivat vastuullisia hallinnollisia tehtäviä palatseissa. Myös kuningatarten ja muiden kuninkaallisten naisten rooli toimijoina oli uusassyrialaisella kaudella merkittävä. Temppeleissä toimineista naisista merkittävin ryhmä toimijuuden kannalta olivat naispuoliset profeetat, jotka toimivat aktiivisissa rooleissa ainakin toimittaessaan jumalallisia sanomia. Palatsien ja temppelien ulkopuolelle jäi vain vähän naistoimijoita: omaksi selkeäksi ryhmäkseen erottuivat ainoastaan harimtut, prostituoidut. Lopuksi pohdin jokaisen ryhmän toimijuutta ensin taulukkomuodossa (taulukot 9, 10 ja 11) sitten lyhyessä analyysikappaleessa.

Bayesian and Decision Tree Approaches for Pattern Recognition Including Feature Measurement Costs

The minimum cost classifier when general cost functionsare associated with the tasks of feature measurement and classification is formulated as a decision graph which does not reject class labels at intermediate stages. Noting its complexities, a heuristic procedure to simplify this scheme to a binary decision tree is presented. The optimizationof the binary tree in this context is carried out using ynamicprogramming. This technique is applied to the voiced-unvoiced-silence classification in speech processing.

The impact of home loan key facts sheets on borrowers' comparisons of loan costs

This thesis evaluates the effectiveness of the prescribed design and distribution requirements of the Australian Government's home loan key facts sheets (KFS) aimed at helping borrowers compare loan costs. The findings show that despite effectively improving borrower decision-making, few borrowers were aware of their existence and function. It was also demonstrated that KFS have had limited market impact over the four year window since introduction, likely due to the requirement that KFS provision is not required unless formally requested by a borrower. Recommendations include transferring the burden of disclosure to lenders in the first instance to address this information gap.
