Participation in higher education for students with disabilities: an Irish perspective

Third level institutions have been encouraged to facilitate greater access and participation for people from marginalized groups who have traditionally been excluded from higher education. In Ireland, as elsewhere, people with disabilities have been included in this process. Few studies have explored the quality of access and participation for students with disabilities within higher education, and this small scale qualitative study aimed to explore this issue. Students with disabilities reported variable access experiences within higher education and physical access remains a serious obstacle to full participation. Generally, there was a low level of awareness of student needs in relation to assistive provision and assessment. A positive and informed staff/college attitude proved crucial in ensuring access and equitable treatment. This research highlights the inherent limitations in the current piecemeal institutional response to provision for students with disabilities. A comprehensive access service is required that addresses the needs of all marginalized groups and becomes an integral part of the third level institution.     

“Living with electronic data interchange: Implementation and practical applications for EDI from the perspective of the ILS vendor,the librarian,and the book vendor,” a report from the ALCTS,automated acquisitions/in-process control systems discussion group session at the ALA midwinter conference,January 1996

Abstract

The libraries in the Western North Carolina Library Network (WNCLN) seek effective ways to provide patrons with a complete list of electronic journals provided through their various aggregator services, so patrons can determine e-journal access to article citations. The WNCLN libraries (Appalachian State University, the University of North Carolina at Asheville, and Western Carolina University) accomplished this through their shared catalog (Innovative Interfaces, Inc. [INNOPAC]), data provided by Serials Solutions, and local computer programming. Brief MARC records, with locally created key titles, provide an interim solution to the complexities of aggregator services. Serials Review 2002; 28:108–112.     

‘Some Good Clean Fun’: Humour,Control and Subversion in an Advertising Agency

This article explores the relation between humour and control, drawing on participant observation in an organization in which humour was central to daily life. Keys is a leading advertising agency whose staff spent an unusually large amount of time sending humorous e‐mails. Examining these e‐mails in some depth, we unpack the role of humour in subverting various forms of control, including gender norms and managerial authority. We find the relation between humour, control and subversion to be ambiguous. Building upon current debates in organization studies, we develop the concept of humour based on our observations at Keys. Specifically, we argue that humour is always in excess of both control and subversion, a ‘nicely impossible’ object that cannot be captured. This article thus contributes to theoretical approaches on organizational humour, conceptualizing the concept of ‘newness’ through Judith Butler's re‐reading of Derridean différance and the Lacanian Real. In addition, we contribute a novel empirical account of the study of e‐mail list humour in a contemporary advertising firm.     

Information and Communication Technologies for Direct Poverty Alleviation: Costs and Benefits

Information and communications technologies (ICTs) are powerful tools for empowerment and income generation in developing countries. The cost‐effectiveness of different ICTs does vary between developed and less developed countries, however. This article reviews the potential efficacy of radio, telephony and the Internet as tools of direct poverty alleviation in the latter. While the requirements for their successful utilisation make radio and telephone far more suitable technologies for the poor, traditional ICTs can act as a sustainable intermediary for them to gain indirect access to the power of the Internet. Governments should concentrate on opening up private and community provision of broadcasting and widening access to telephone services, so that they can effectively play this intermediary role.     

Responses to prenatal opioid and alcohol abuse: A review of US and Australian mandatory reporting laws

Prenatal substance use, specifically opioid and excessive alcohol use, can cause significant adverse effects for the unborn foetus in both the short-and long-term. Responses by state social systems occur on a spectrum of prevention and early intervention to support mothers. Some but not all states include reporting duties, so that professionals made aware of the situation may alert agencies that can intervene to provide appropriate support. This article will review legal duties to report maternal substance use during pregnancy in the US and Australia. We identify variations in these laws regarding who is required to report, what circumstances must be reported and what indicates child abuse or neglect. Inconsistencies in laws raise questions about the nature of different approaches, and how reforms might be made to improve provision of support. Informed by the medical literature, the contemporary context and federal policy in the US, we make recommendations for reform, and for the appropriate response to such reports.     

Calculation of Benchmark Doses from Continuous Data

A benchmark dose (BMD) is the dose of a substance that corresponds to a prescribed increase in the response (called the benchmark response or BMR) of a health effect. A statistical lower bound on the benchmark dose (BMDL) has been proposed as a replacement for the no-observed-adverse-effect-level (NOAEL) in setting acceptable human exposure levels. A method is developed in this paper for calculating BMDs and BMDLs from continuous data in a manner that is consistent with those calculated from quantal data. The method involves defining an abnormal response, either directly by specifying a cutoff x₀ that separates continuous responses into normal and abnormal categories, or indirectly by specifying the proportion P₀ of abnormal responses expected among unexposed subjects. The method does not involve actually dichotomizing individual continuous responses into quantal responses, and in certain cases can be applied to continuous data in summarized form (e.g., means and standard deviations of continuous responses among subjects in discrete dose groups). In addition to specifying the BMR and either x₀ or P₀ , the method requires specification of the distribution of continuous responses, including specification of the dose-response θ(d) for a measure of central tendency. A method is illustrated for selecting θ(d) to make the probability of an abnormal response any desired dose-response function. This enables the same dose-response model (Weibull, log-logistic, etc.) to be used for the probability of an abnormal response, regardless of whether the underlying data are continuous or quantal. Whenever the continuous responses are normally distributed with standard deviation σ (independent of dose), the method is equivalent to defining the BMD as the dose corresponding to a prescribed change in the mean response relative to σ.     

Evaluation of the Uncertainty in an Oral Reference Dose for Methylmercury Due to Interindividual Variability in Pharmacokinetics

An analysis of the uncertainty in guidelines for the ingestion of methylmercury (MeHg) due to human pharmacokinetic variability was conducted using a physiologically based pharmacokinetic (PBPK) model that describes MeHg kinetics in the pregnant human and fetus. Two alternative derivations of an ingestion guideline for MeHg were considered: the U.S. Environmental Protection Agency reference dose (RfD) of 0.1 g/kg/day derived from studies of an Iraqi grain poisoning episode, and the Agency for Toxic Substances and Disease Registry chronic oral minimal risk level (MRL) of 0.5 g/kg/day based on studies of a fish-eating population in the Seychelles Islands. Calculation of an ingestion guideline for MeHg from either of these epidemiological studies requires calculation of a dose conversion factor (DCF) relating a hair mercury concentration to a chronic MeHg ingestion rate. To evaluate the uncertainty in this DCF across the population of U.S. women of child-bearing age, Monte Carlo analyses were performed in which distributions for each of the parameters in the PBPK model were randomly sampled 1000 times. The 1st and 5th percentiles of the resulting distribution of DCFs were a factor of 1.8 and 1.5 below the median, respectively. This estimate of variability is consistent with, but somewhat less than, previous analyses performed with empirical, one-compartment pharmacokinetic models. The use of a consistent factor in both guidelines of 1.5 for pharmacokinetic variability in the DCF, and keeping all other aspects of the derivations unchanged, would result in an RfD of 0.2 g/kg/day and an MRL of 0.3 g/kg/day.     

Influence of Prenatal Mercury Exposure Upon Scholastic and Psychological Test Performance: Benchmark Analysis of a New Zealand Cohort

This paper presents benchmark (BMD) calculations and additional regression analyses of data from a study in which scores from 26 scholastic and psychological tests administered to 237 6- and 7-year-old New Zealand children were correlated with the mercury concentration in their mothers' hair during pregnancy. The original analyses of five test scores found an association between high prenatal mercury exposure and decreased test performance, using category variables for mercury exposure. Our regression analyses, which utilized the actual hair mercury level, did not find significant associations between mercury and children's test scores. However, this finding was highly influenced by a single child whose mother's mercury hair level (86 mgkg) was more than four times that of any other mother. When that child was omitted, results were more indicative of a mercury effect and scores on six tests were significantly associated with the mothers' hair mercury level. BMDs calculated from five tests ranged from 32 to 73 mgkg hair mercury, and corresponding BMDLs (95% lower limits on BMDs) ranged from 17 to 24 mgkg. When the child with the highest mercury level was omitted, BMDs ranged from 13 to 21 mgkg, and corresponding BMDLs ranged from 7.4 to 10 mgkg.
