AbstractSpurred by Kilpatrick’s (1987) “Where do good problems come from?”, this study explores problem-posing triggers of experienced problem posers for mathematics competitions. Triggers are conceived as instances of noticing, where an impulse draws a poser’s attention and “triggers off” a mathematical re-action, one of the outcomes of which is a creation of a problem that gets accepted to some mathematics competition. The data were collected from 26 problem posers residing in nine countries, and who had experience in creating problems for national, regional, and international competitions. Three types of triggers emerged from the analysis: (i) Instances where the participants extracted mathematical phenomena from activities that are replete with modern elementary mathematics. These triggers were described in emotionally loaded terms that resonated with appreciation, surprise, challenge, and feeling of innovation. (ii) Cases where the participants abstracted mathematical phenomena from common everyday-life tasks in which mathematical optimization was beneficial. These situations emphasized participants’ desire to compensate for self-disappointment with an initially made decision and the value of finding a better alternative. (iii) Situations where the participants were asked to pose a problem ‘here and now’. The posers were unanimous in their dislike of such situations. They elaborated on how difficult it is to pose ‘here and now’ and highlighted the low quality of the resulting problems. The findings are situated in the body of knowledge on expert problem posing and educational literature on school students and teachers.

The 19Th Century

The teaching of chemistry in Serbia as a separate subject dates from 1874. The first secondary-school chemistry textbooks appeared in the second half of the 19th century. The aim of this paper is to gain insight, by analysing two secondary-school chemistry textbooks, written by Sima Lozanic (1895) and Mita Petrovic (1892), into what amount of scientific knowledge from the sphere of chemistry was presented to secondary school students in Serbia in the second half of the 19th century, and what principles textbooks written at the time were based on. Within the framework of the research conducted, we defined the criteria for assessing the quality of secondary-school chemistry textbooks in the context of the time they were written in. The most important difference between the two textbooks under analysis that we found pertained to the way in which their contents were organized. Sima Lozanic?s textbook is characterized by a greater degree of systematicness when it comes to the manner of presenting its contents and consistency of approach throughout the book. In both textbooks one can perceive the authors? attempts to link chemistry-related subjects to everyday life, and to point out the practical significance of various substances, as well as their toxicness.

The aim of this paper is to review and analyse the importance of the framework for urban farming activities to be implemented within cities environment. This paper also describes the role of the community to achieve the environmental, economic and social sustainability for the enhancement of the urban environment and healthy lifestyles through community participation in food supplies,nutrition, and spaces utilization. The paper evaluates the benefits and potential of urban farming activities within limited urban spaces and how it improves the quality of life. It also reviews on how urban farming is beneficial to the society due to food shortage crisis which is inadequate for the whole population. It is necessary to apply and practice in our daily lives for the consumption of food security, human safety, and health. Therefore, the role of community is very crucial in the implementation of urban farming activities within urbanized areas as the demand for green development increases. Based on this theoretical framework, it is hoped that the paper will be a useful addition to the body of knowledge in promoting a stronger community interdependence to create the sustainable urban environment.

Investor relations is the field of management that is concerned with the relationships between companies and investors, and as such involves a wide variety of information types, for example mandatory, voluntary, financial, non-financial, qualitative and quantitative. While South Africa has recently been ranked number one for the strength of its auditing and reporting standards for the seventh consecutive year (IRBA, 2016), investor relations as a wider and voluntary concept, is largely un-researched in South Africa. The purpose of the study was to establish the determinants of Internet investor relations (IIR).The quality of IIR was measured for a sample of 85 JSE-listed companies using a measurement instrument that consists of 346 attributes. From the literature, as discussed in the literature review, 15 company characteristics were identified that could explain IIR quality. Stepwise regression model-building was used to develop a regression model that best explains IIR quality.Company size, leverage, being audited by a big four audit company, JSE industry membership, free float and dual listing status were found statistically significant independent variables, explaining 68.76% of the variation in the dependent variable, IIR. Contributions to the body of knowledge, study limitations and the need for further research are discussed in the conclusion.

Purpose The purpose of this paper is to examine the relative merits of thesis consultation with a librarian prior to graduate submission and to explore whether thesis consultation has a significant impact on the quality of the theses submitted by postgraduate students. Design/methodology/approach This study uses a quantitative case study approach. The total number of thesis scrutiny reports written by librarians between 2009 and 2014 has been reviewed for errors found in theses. Errors have been classified as referencing errors and formatting errors. These have been compiled in a spreadsheet and analyzed using the SPSS statistical package. Findings This paper highlights that thesis consultation has had a positive impact on the quality of the theses students submitted for examination at the University of the West Indies, Mona Campus. Thesis consultation with a strong focus on referencing clearly assisted students learning and applying different citation styles. There was a decrease in the number of referencing errors over time. Not much difference was seen in terms of formatting errors. Further tests showed that there was a statistically significant positive relationship between thesis consultation and the number of referencing errors made by graduate students. Practical implications This study may have implications for the engagement of academic libraries with their graduate communities. With thesis consultation, a librarian may scrutinize the same thesis more than once. Although this may increase the workload of librarians, thesis consultation/scrutiny will have a positive impact on the quality of research produced by graduate students. Originality/value This study shows that students benefited from thesis consultation and there was a significant reduction in citation errors. In reviewing the literature, it has been noted that research done in the area of thesis consultation was very limited; hence, this study significantly contributes to the body of knowledge that presently exists.

Abstract: Museums have become an important institution for learning activities especially for young visitors as it provides significant function towards educational benefits and knowledge enrichment. The actual outcomes from learning experience need to be encountered in order to indicate satisfying experience level from museum visiting. However, the assessment of satisfying experience on museum visit is entirely lacking in the existing literatures. Therefore, this study proposes a set of assessment for young visitors in order to evaluate their satisfying experiences in museum. The items were adapted and developed from the concept of satisfying experiences established by museum practitioners. This paper aims to present evidence in order to show the validity of the survey data and the instrument meets the requirements of specific measurements as determined by Rasch model. It is hoped that the assessment of satisfying experience will benefit researchers as well as practitioners and educators in managing the quality of young visitors experience in museum. The literature also intends to add to the body of knowledge in museum context.   Keywords: Learning, Museum, Rasch model, Satisfying experiences, Young visitors

Audit Standards

The literature has highlighted the increased pressure on the auditing profession to achieve global harmony in auditing practice (i.e. Humphrey et al., 2009; Michas, 2011; Holm & Zaman, 2012), thereby requiring auditing regulators and standards-setters to revise and improve auditing standards in their own local contexts. This study seeks to determine the contemporary conduct and determinants of local auditing practice and offers an analysis of how Libyan audit stakeholders perceive the prospect of adopting harmonised auditing standards or developing such a set of standards for local use. A survey was completed by 196 respondents, representing five stakeholder groups in the Libyan auditing arena. Statistical analysis, via the SPSS, was performed. The outcomes are deemed to be generalizable given the size of the sample. This study has found that the Libyan Accounting and Auditing practice have varied according to variable concerning the personnel involved. And that the result is an overall poor quality of audit work in the country. This needs to be raised, and the harmonisation of audit standards is one way to achieve not only this but a greater degree of credibility in the country’s financial reporting. The study contributes to the body of literature in respect of the Libyan accountancy environment by specifically exploring the perception of stakeholders towards the adoption of harmonised audit standards. By implication, it makes a contribution to the wider body of knowledge about auditing in the Arab countries, where similar cultural conventions and attitudes exist.

Purpose The purpose of this paper is to understand different preferences and important design factors for wearable soft robots (WSR) and understand how these differences affect people’s perception, attitude and behavioral intentions toward using the WSR. Design/methodology/approach An online survey was conducted to purposely sampled participants who are adults aged over 18 of both genders with movement disabilities living in the USA. The collected data were analyzed through Welch’s t-test, Welch’s analysis of variance and linear- and multi-regressions for quantitative data and major theme extractions for qualitative data. Findings The results identified preferred functions and designs and important design factors for WSR and how these influence to users’ perception, attitude and behaviors on WSR. Originality/value The number of people with movement disabilities is anticipated to increase worldwide and it is essential to understand users for developing wearable movement aids for people with movement disabilities. However, there is no research on what functions and designs are preferred by WSR users and what aspects designers need to consider when developing these WSR. Thus, this research will contribute to the body of knowledge in WSR design; help WSR developers, designers and researchers better incorporate users’ preferences in the design process; and ultimately enhance the quality of life of people who have movement disabilities.
