Sudden drawdown and drainage of a horizontal aquifer

Drainage of a saturated horizontal aquifer following a sudden drawdown is reanalyzed using the Boussinesq equation. The effect of the finite length of the aquifer is considered in detail. An analytical approximation based on a superposition principle yields a very good estimate of the outflow when compared to accurate numerical solutions. An illustration of the new analytical approach to analyze basin-scale field data is used to demonstrate possible field applications of the new solution.

Including teachers as 'real' partners in child protection

Simultaneous downsizing of child protection services and increasing numbers of child abuse notifications often result in many notifications remaining un-investigated. One possible solution to this problem is to extend the capacity of the child protection system by delegating some of the tasks commonly undertaken by child protection workers to allied professionals. One such group of allied professionals is teachers. In the past, teachers have been recognised for their unique role in notifying suspicions of abuse, however, education professionals are often overlooked for their potential to contribute more than they currently do to child protection. In this paper we suggest that teachers can be included as 'real' and credible partners in the child protection process in a way not previously considered possible.

Protection versus promotion: an empirical investigation

Using Turkish industry-level data from 1983 to 1990, we find that politically organized industries receive both higher protection and promotion than unorganized ones. Tariff rates are decreasing (increasing) in the import-penetration ratio and the absolute value of the import-demandelasticity for organized (unorganized) industries. Subsidy rates are decreasing (increasing) in the output-supply elasticity for organized (unorganized) industries. The results are consistent with the predictions of the Grossman–Helpman model and its extension in this paper. The mix of protection and promotion is inversely related to the ratio of their respective marginal deadweight cost measures.

A comparison study of cerebral protection using Ginkgo biloba extract and Losartan on stroked rats

It has been well documented that oxidative stress is involved in stroke. Currently, many neuroprotective strategies have been targeted at molecules that are able to act as an oxidant to intervene with free-radical mediated apoptosis in the ischemic penumbra. In particular, natural products which contain antioxidant properties have undoubtedly efficacious for stroke treatment. In the current study, therapeutic effects of Ginkgo biloba extract (EGb) against cerebral protection in Wistar rats underwent middle cerebral artery occlusion (MCAO) was evaluated. A comparison study was conducted by using Losartan, an antihypertensive drug. Gene expression levels of pro-apoptotic genes (AT2 receptor, Fas, Bax and Bcl-xS) have shown to have significant reduction by EGb- and Losartan-treated groups as compared to vehicle group. Significant reduction of immunoreactivity of protein production of these genes, together with least nuclear green fluorescence observed in TUNEL, EGb, as an antioxidant drug, is concluded to have potent and promising therapeutic effect for stroke treatment.

Clinical supervision in child protection for community nurses

Community nurses have been recognized as having a key role in the protection and care of children, particularly in relation to the identification and detection of child abuse. In order to fulfill this role in a competent manner, they need to have access to appropriate supervision. The aim of this paper is to explore community nurses' and health care managers' understanding and experience of clinical supervision in child protection. The findings presented here were collected as part of a larger study commissioned by the Greater Glasgow Primary Health Care National Health Service (NHS) Trust. Ninety-nine nurses and nursing managers were interviewed, either individually or in groups, about their professional involvement in child protection issues and support for their involvement in child protection work, as well as their current knowledge and perceived training needs. The interview data was subjected to a thematic analysis. A lack of consensus was found among nurses and managers in Glasgow as to what constitutes clinical supervision and a good deal of variation in nurses' experiences of clinical supervision in the field of child protection. The historical difficulties with regard to supervision were attributed to several aspects of nursing culture. However, both nurses and managers emphasized the need for formal, regular, systematic supervision for all nurses regardless of their specific role with regard to child protection.

Risk and protection factors for different intensities of adolescent substance use: when does the prevention paradox apply?

The 'Prevention Paradox' applies when low-risk individuals in a population contribute the most cases of a condition or problem behaviour by virtue of their being in the majority, thereby recommending a universal or whole of population approach to prevention. The applicability of a universal as opposed to a targeted high-risk approach to the prevention of youth substance use was examined in two studies of children and adolescents conducted in Victoria, Australia. These studies were reanalysed by recombining developmental, social and individual measures to form cumulative risk indices for substance use. In Study 1, a cross-sectional survey of students, most regular tobacco, alcohol and cannabis use by 15/16-year-olds occurred in the moderate and low-risk groups, recommending a universal prevention strategy . However, the majority of illicit drug use occurred in the highest-risk group (top 15%). Furthermore, in younger age groups both legal and illegal drug use was concentrated mainly in the highest risk group. Study 2 used data from a major longitudinal study where risk factors at around age 11/12 years were used to predict substance use at age 17/18 years. Most students who admitted involvement in frequent smoking, heavy drinking and, although to a lesser degree, cannabis were classified as low or average risk. It is concluded that universal prevention strategies are needed for late adolescent alcohol, tobacco and cannabis use and more targeted strategies for addressing harm related to early age drug use, frequent cannabis use and illegal drug use.

Educating teachers in child protection : lessons from research

This paper examines research about child protection preparation of teachers. Such research indicates that the nature of the training required to "do the public good" would differ markedly from that which is currently on offer in most teacher education courses. Whilst teachers have the potential to operate as frontline respondents in combating child abuse, the limitations of their training create a situation in which they are "worried, lacking in confidence and stressed about their ability to comply with mandatory reporting legislation" (Bluett, 2002). The consequences to the community are substantial: not only are there disincentives for teachers to participate in child protection roles and the increased likelihood of poor quality reporting, but children subjected to abuse may be unable to access protective services via the school system. The paper distills the findings of recent studies to identify design parameters for effective teacher preparation in child protection. The paper concludes that a program informed by research has the potential to produce enhanced outcomes for children, teachers and the broader community.

Commercial critical systems and critical infrastructure protection : a future research agenda

Secure management of Australia’s commercial critical infrastructure presents ongoing challenges to owners and the government. Although it is currently managed through high-level information sharing via collaboration, but does this suit the commercial sector. One of the issues facing Australia is that the majority of critical infrastructure resides under the control of the business sector and certain aspects such of the critical infrastructure such as Supply Chain Management (SCM) systems are distributed entities and not a single entity. The paper focuses upon the security issues associated with SCM systems and critical infrastructure protection.
