Abstract
For many years it has been speculated that some learning and attention problems in children are related to underlying problems in neurological functioning. In fact, the IDEA (1997) definition of learning disabilities utilizes terminology that specifically includes neurological processes and conditions: Specific learning disabilities means a disorder in one or more of the basic psychological processes involved in understanding or in using language, spoken or written, which may manifest itself in an imperfect ability to listen, think, speak, read, write, spell, or do mathematical calculations. The term includes such conditions as perceptual handicaps, brain injury, minimal brain dysfunction, dyslexia, and developmental aphasia. The term does not include children who have learning problems which are primarily the result of visual, hearing, or motor handicaps, of mental retardation, or of environmental, cultural, or economic disadvantage.This chapter begins with a review of the role of neuroimaging in advancing an understanding of the basis and nature of learning and attention problems. The ever-increasing sophistication of neurodiagnostic technology has made it possible to obtain more precise information about neuroanatomical and neurophysiological bases of behavior, including learning and attention. Advances in technology have greatly increased the ability to study the functioning of the brain during the performance of relatively complex mental activities. With this advanced technology it is becoming increasingly possible to visualize normal and abnormal brain functioning, including important components of basic academic skills. The chapter includes a discussion of the recent evidence about the neurological basis of learning and attention problems.

Abstract
This chapter reviews problems in the identification of learning disabilities, with particular reference to issues involving discrepancy between IQ and achievement as a criterion for definition. Alternatives to present procedures for identification of learning disabilities are described. It is concluded that no presently proposed alternative meets all necessary criteria for identification of learning disabilities, and that radically altering or eliminating present conceptualizations of learning disabilities may be problematic. The major problems of identification of learning disabilities – including over-identification, variability, and specificity – can be addressed, it is suggested, by increasing specificity and consistency of state criteria and strict adherence to identification criteria on the local implementation level. However, further research in alternative methods for identifying learning disabilities is warranted.

Abstract
Purpose
The purpose of this paper is to investigate the validation of the ASEAN+3 financial cooperation agreement among its members. In particular, it examines the long- and short-run relationships among the stock market indices of eight countries: China (CH), Japan (JP),Korea (KR), Malaysia (MY), Indonesia (ID), Philippines (PH), Thailand (TH), and Singapore (SG).
Design/methodology/approach
The study applied a global VAR and vector error correction model (VECM) model to investigate this relationship using daily data over the period from first March 1992 to end of September 2013. The study period has been separated into pre-1997/1998 financial crisis period (1992-1997) and post-1997/1998 crisis period (1999-2013).
Findings
The findings show that the stock markets in the ASEAN region are integrated during both periods of financial crises. However, the markets are moving toward better integration, particularly during the post-crisis period. This is supported by the results of the error correction which indicated that most ASEAN+3 stock market indices adjust quickly within the short run to a shock in the long-run equilibrium relationships in the region during both the pre- and post-crisis periods. In addition, the results of the VECM causality test showed that a short-run relationship exists among the ASEAN+3 stock market indices.
Practical implications
The results of this study therefore have two implications: first, for investors in terms of construction of the portfolio diversification strategies across difference stock markets in Asian region, and second, for policy makers, as the study presents an understanding of financial exposure in their countries as consequences of changes that occur in the other stock market indices in the ASEAN region.
Social implications
The investors can find the potential sectors for the portfolio investments.
Originality/value
The paper is one of the pioneers to examine the validity of ASEAN+3 financial cooperation agreement.

Abstract
Purpose
The purpose of this paper is to examine the reaction to earnings announcements in a small stock market.
Design/methodology/approach
The paper uses the traditional event study method to examine the information content of annual earnings announcements in the small Danish stock market from 1999‐2004.
Findings
The paper finds abnormal volatility in the days surrounding the announcements, indicating that they contain relevant information for the stock market. The abnormal volatility persists several days after the announcement, suggesting that the information environment of this small stock market works to decrease the speed of adjustment. In addition to this sign of inefficiency, the paper finds significant positive abnormal returns accompanying the announcements. These results are robust across various methodologies. Surprisingly, the paper finds a positive correlation between the information content and predisclosure information. This contradicts previous studies, and it is interpreted as evidence of a low level of pre‐announcement information. Confirming the results of similar studies, the paper finds that unexpected earnings are best proxied using a model based on consensus analyst forecasts.
Originality/value
This paper contributes to the existing literature by analyzing the information content of earnings announcements in a small stock market with accounting standards that are congruent with the International Accounting Standards.

Abstract
Paints are dynamic systems which are in an almost constant state of change throughout their whole life. These changes are evident from the time of manufacture and througout storage when the liquid paint can undergo major rheological changes due to binder adsorption, crosslinking or, with waterborne systems, biological attack, as well as associated problems such as pigment instability. When in service the dried film also exhibits progressive changes. These occur in both surface properties by erosion, loss of gloss colour change, and also in bulk properties by, for example, embrittlement. Both are often due to structural changes within the cured film and can be due to a variety of external causes such as solar radiation, oxidation or chemical attack.

Abstract
The governmental public health workforce provides essential public health services to communities from public health agencies operations at the local, state, and federal levels of government. The roles and duties of public health workers range from infectious disease tracking and control to healthy eating promotion to checking food service establishments for safety. Unfortunately, most of the time, the general public is unaware of, and unconcerned with, public health’s primary mission of disease prevention. This behind-the-scenes, service-oriented workforce has responded to the COVID-19 pandemic by working long hours, extra days, and ever-changing job roles, all while becoming targets of political attacks and enduring substantially elevated psychological distress and burnout. Though this workforce is not well enumerated, existing studies indicate that public health workers face higher anxiety, depression, post-traumatic stress disorder, and burnout than other frontline healthcare workers during the COVID-19 pandemic response. Several strategies have been suggested to address these vulnerabilities, including increasing the amount and stability of available funding, implementing organizational-level policies and programming to boost resilience, and providing individual-level social support, both instrumental and emotional, to protect against burnout and other psychological distresses.

Abstract
Purpose
The ongoing demographic changes in many industrialized countries affect managerial decisions in many ways, and require sound knowledge of systematic age differences in central work-related variables. The current paper aims to address age differences in the experience of work-related stress. Based on life-span approaches, the authors focus on age differences in different components of the work-related stress process and meta-analyze existing empirical studies on the relationship between age and short-term indicators of work-related stress (i.e. irritation).
Design/methodology/approach
The authors conduct both a literature review and a meta-analysis of age and indicators of work-related stress.
Findings
The literature review revealed that age might affect several components of the stress process at work. However, as these effects are partly conflicting, they might nullify each other in the overall relation between age and stress. Indeed, the conducted meta-analysis showed no general correlation between age and irritation as a short-term indicator of work-related stress. Instead, this relationship was significantly moderated by type of occupation and gender.
Research limitations/implications
The meta-analytic results are limited to short-term indicators of stress. Based on both the literature review and the meta-analytical findings, the authors introduce a research agenda for future research, including a call for more thorough research on the whole work-stress process and the integration of life-span theories.
Practical implications
A more differentiated understanding of age differences in different stages of the stress process at work facilitates the implementation of age-differentiated stress prevention and intervention strategies.
Originality/value
This study is the first meta-analysis on the relationship between age and short-term consequences of work-related stress.

Abstract
Purpose
The landscape of teaching, learning and research has changed requiring the need for diverse information resources. Given the current budgetary constraints and financial conditions prevailing in many universities, sharing of information resources has become a necessity. The Interlibrary Loan (ILL) services have thus become an important service to meet the immediate needs of library users. The aim of this paper is to analyse the ILL services of the North-West University in South Africa from 2006 to 2016. Using statistical data, the paper shows the emerging pattern in borrowing and lending between institutions as well as determines the existence of correlations between borrowing and lending libraries. The results of this study show that ILL amongst libraries has decreased in the past 11 years. A need exists for increased awareness of ILL and there is need for technological innovations that will ensure that library users are able to request for information resources seamlessly.
Design/methodology/approach
This is a quantitative study that uses ILL data from the North-West University. Data were downloaded from the SABINET ILL system using the three NWU JC codes. They were then collated and uploaded on excel spreadsheets. In the main, the excel spreadsheets were used to interpret the data. Further, the Statistical Package for Social Sciences (SPSS) software, in particular Spearman’s Correlation Analysis, was used to test correlations between data from libraries that requested information resources from NWU and data from libraries that supplied information resources to NWU during this period using Rumsey’s guidelines to interpret the correlations.
Findings
The findings of the study reveal that ILL among libraries in South Africa had generally declined owing mostly to the proliferation of online resources resulting to changes in user information-seeking behaviour. The decline is despite the challenges of low budgets received by most libraries for the acquisition of information resources. It can also be concluded that public university libraries still value ILL as demonstrated by the high number of items requested from other libraries. The findings also reveal that most ILL activities were conducted by public universities.
Research limitations/implications
It was not possible to obtain the list of titles that have been requested and also to obtain the user’s details. This would have enabled the authors to determine the type of titles that are being requested, and the users that request them.
Practical implications
ILL should continue to be enhanced in view of the challenge of dwindling library budgets against the escalating prices of information resources. There is also a need for user education so that they become aware of the ILL service. From experience, library users normally give up once they realize that what they wanted is not available through the local catalogue and this calls for librarians to create an awareness to users that ILL could help solve their frustrations.
Social implications
These results show that ILL can play a significant role to level the playing field between the well-resourced libraries in urbanized regions or provinces and the poorly resourced ones in rural regions or provinces. This social justice aspect of ILL is probably the reason why better resourced libraries in South Africa have decided to remain in the scheme unlike other countries where better resourced libraries opted out of reciprocal arrangements with small and medium-sized institutions.
Originality/value
The study adds to a very limited number of studies emanating from Africa. A study of this nature has never been conducted in Africa, as previous studies were nationwide studies. As far as the authors know, this is the first study that uses ILL data to research the impact of the global financial crisis on libraries in Africa.
