Abstract

Purpose

This study aims to investigate the correlation between neural indexes of attention and behavioral indexes of attention and detect the most informative period of brain activity in which the strongest correlation with attentive performance (behavioral index) exists. Finally, to further validate the findings, this paper aims at the prediction of different levels of attention function based on the attention score obtained from repeatable battery for the assessment of neurophysiological status (RBANS).

Design/methodology/approach

The present paper analyzes electroencephalogram (EEG) signals recorded by a single prefrontal channel from 105 elderly subjects while they were responding to Stroop color test which is an attention-demanded task. Beside Stroop test, subjects also performed RBANS which provides their level of functionality in different domains including attention. After data acquisition (EEG during Stroop test and RBANS attention score), the authors extract the spectral features of EEG as neural indexes of attention and subjects’ reaction time in response to Stroop test as behavioral index of attention. Then, they explore the correlation between these post-cue frequency band oscillations of EEG with elderly response time (RT). Next, the authors exploit these findings to classify RBANS attention score.

Findings

The observations of this study suggest that there is significant negative correlation between alpha gamma ratio (AGR) and RT (p < 0.0001), theta beta ratio (TBR) is positively correlated with subjects’ RT (p < 0.0001), these correlations are stronger in a 500ms period right after triggering the cue (question onset in Stroop test), and 4) TBR and AGR can be effectively used to predict RBANS attention score.

Research limitations/implications

Because of the experiment design, the pre-cue EEG of the next trail was very much overlapped with the post-cue EEG of the current trail. Therefore, the authors could analyze only post-cue EEG. In future study, it would be interesting to investigate the predictability of subject’s future performance from pre-cue EEG and mental preparation.

Practical implications

This study provides an insight into the research on detection of human attention level from EEG instead of conventional neurophysiological tests. It has also potential to be used in implementation of feasible and efficient EEG-based brain computer interface training systems for elderly.

Originality/value

To the best of the authors’ knowledge, this study is among very few attempts for early prediction of cognitive decline in the domain of attention from brain activity (EEG) instead of conventional tests which are prone to human errors.

Abstract

Purpose

The purpose of this paper is to increase awareness and compliance of The National Institute for Health and Care Excellence (NICE) Guidance regarding cognitive impairment in multiple sclerosis (MS).

Design/methodology/approach

Assessments were offered routinely to consecutive inpatients with MS and to 20 per cent of outpatients. Once consent was gained, a cognitive assessment and subjective measure of cognition was completed with the patient, as well as a disability scale completed by the Medical Consultant. Individually targeted cognitive rehabilitation advice was provided using a bespoke advice leaflet. Afterwards, those who completed the assessment were asked to provide feedback on their experience.

Findings

The percentage that were classed as below average cognitively and the pattern of impairment was comparable to previous findings. Memory was rated the most affected by the largest number of MS individuals and a strong relationship was found between objective and subjective measures of attention. The average functional disability level was rated at 6.99. Evaluations for the service provided were positive; over half of the sample was unaware of NICE Guidance on this issue but 100 per cent would recommend this service and provided optimistic quotes.

Practical implications

This evaluation has enabled greater numbers to receive the recommended services and provided a useful baseline assessment of cognitive impairment and of patient attitudes towards this service. Resulting from this process, a new service framework has been proposed and presented at a local level. The advice leaflet developed for this process has been well received by patients and colleagues resulting in its submission to become an official NHS leaflet.

Originality/value

Developed clinical governance of NHS services to patients with MS in offering improved assessment and management of cognitive problems. This is in contrast to the national trend showing little improvement of MS care and the lack of NICE implementation by the MS Trust and Royal College of Physicians audit. Furthermore, the bespoke advice leaflet developed for patients and carers of MS demonstrates originality of information provided.

Abstract

Recreational needs, their resulting demands and ensuing supply systems have become an increasingly difficult matter for society to manage and to establish consistent policies for. The difficulty seems to arise out of the two basic elements that constitute the recreational mosaic: first we have the difficulty in establishing what constitutes recreational needs for large populations and what are the characteristics and levels of recreational demand for various activities; secondly, even if one can arrive at reasonably accurate measurements of recreational demand levels, it is exceedingly difficult to construct a set of mechanisms, which in a coordinated way can monitor the supply, and the same time can do this according to principles consistent with good land management.

Abstract

Purpose

This literature review identifies instruments for diagnostic assessment of cognitive impairment in prison populations. The purpose of this paper is to promote procedures for early screening and identification of cognitive impairment using instruments appropriate to prisons.

Design/methodology/approach

A targeted literature review identified studies on screening and diagnostic assessment of adults in jails, prisons, police watch-houses (custody suites), rehabilitation facilities and forensic settings or community settings for offenders. Discriminant validity, suitability, reliability and feasibility of instruments in correctional and forensic settings are presented.

Findings

From 135 peer-reviewed articles relating to diagnostic assessment of cognitive impairment, 15 instruments were considered appropriate for use in prison settings.

Research limitations/implications

Selection of instruments for prison use considers suitability of the instrument(s) and clinical workforce capability. Cultural and gender validity of the instrument, its feasibility for use in the prison environment and cost and time to administer are also important. Using appropriate tools as part of a staged and targeted process in the screening and diagnosis of cognitive impairment is demonstrated by two case vignettes presented in this paper. As this was a desk review, the authors did not evaluate the instruments.

Originality/value

Identification of instruments that are suitable for diagnosis of cognitive impairment in forensic populations informs the rehabilitation of offenders with cognitive impairment in prison and upon release to probation and parole.

Abstract

Investigates urban bias in state policy making in Mexico. Refers to literature claiming that rural poverty in developing nations is a major problem because capitalism reflects an urban bias. Examines social security coverage for the rural poor in Mexico and notes that there are great variations depending on area, suggesting that social security coverage is politically negotiable. Outlines briefly the historical development of Mexico’s welfare state and uses a power resource model to demonstrate how groups with competing interests go about securing benefits from the state. Cites literature on dependency theory, indicating that rural groups have failed to mobilize politically and have therefore not secured the same state resources (such as social security benefits and housing) as urban groups, yet argues that this does not always apply in Mexico, partially due to party politics and bureaucratic paternalism. Explains how data was collected to examine regional variations in social security coverage among the rural poor and how the data was analysed. Reveal that workers in important international export markets (such as cotton and sugar) have greater political leverage in obtaining better social security benefits. Notes also that areas supporting the political party in power obtain better benefits. Concludes, therefore, that rural workers are not powerless in the face of urban capitalism and that urban bias and dependency theories do not reflect the situation in Mexico – rather social security benefits are politically negotiable.

Abstract

Discusses prevention of lead poisoning among US children, claiming that it is entirely preventable yet is the most common environmentally induced disease in children. Outlines the extent of the problem then focuses on legislation, what the various acts were meant to achieve, and how they can be enforced. Explains how sociological skills were used in the author’s work for the US Department of Housing and Urban Development. Indicates that sociologists can help in a number of fields not immediately linked to sociology.

Abstract

Draws on data from the 1989 Bangladesh Fertility Survey to explore whether or not socio‐demographic factors such as woman’s age, education, occupation, income and residence affect fertility because of different attitudes towards decision making and the use of contraception. Describes the methodology used and forms of data analysis – path modelling via LISREL. Analyses the findings – that as the woman’s age increases so does the number of children ever born, women who have not completed primary education have more children than women who have completed secondary or higher education, urban women have fewer children than rural women, and women with more education and a higher income have more autonomy in decision making, consequently are more likely to use contraception and have fewer children. Reports that when men make the decisions, families are larger and infers that there are policy implications in that finding. Concludes that the determining factors affecting fertility and use of contraception in Bangladesh are the woman’s level of education, residence in urban or rural areas, and the extent of inter‐spouse communication.

Abstract

Purpose

Advancing knowledge about effectively managing the ageing workforce and ensuring economic sustainability for a growing retired cohort is a recognised priority for organisational health researchers, employers and governments. The purpose of this paper is to test social perceptions that older workers' cognitive performance and job attitudes compare adversely to their younger colleagues.

Design/methodology/approach

The research assessed samples of older and younger workers in objective tests of cognitive abilities and subjective job attitudes. An opportunity sampling method was employed to recruit a heterogeneous group of participants in Australia (n=172).

Findings

No significant differences in cognitive ability between the groups were identified; older workers were as cognitively skilled for their job as their younger colleagues. No significant group difference for perceptions of social support, job commitment, job satisfaction or turnover intentions was identified.

Research limitations/implications

The cross‐sectional research design adopted by this research prevented a more detailed examination of the data in terms of causal relationships. While the cognitive testing provided objective rather than subjective data and, therefore, is not as susceptible to response biases such as common method variance, the small sample who undertook the cognitive testing is acknowledged as a research limitation.

Social implications

This research has implications for the reduction in unemployment of older workers and directly addresses the social issues of an ageing labour force.

Originality/value

The paper demonstrates that stereotypical assumptions concerning inadequate performance and low job commitment commonly attributed to older workers are not in fact indicative of all ageing employees.

Abstract

Within the past ten years Canada has experienced a renewed interest in its architectural past. Whether part of an international trend toward architectural conservation (witness European Architectural Heritage Year, 1976), or part of a general reappraisal of all things Canadian and the development of a sense of nationalism, or the realization, painful as it may be, that the character of the urban landscape is quickly losing its familiar character, this renewed interest in our architectural heritage has surfaced, and is manifesting its presence in many ways. To any who would doubt the existence of a Canadian architectural heritage, or would quarrel with its worth, one has only to turn to Alan Gowans' prefatory remarks to his Building Canada: An Architectural History of Canadian Life:
