This paper aims to investigate the use of calcined mussel shell (CMS) ash–cement mix in concrete that is found to increase the concrete resistance against carbonation.

The deposited ash from the calcination of the mussel shells at 1000°C was used to replace the ordinary Portland cement at 5 and 7 per cent of the cement weight. The test results from the control concrete specimens were compared to the test results from the experimental concrete specimens to analyse the effects due to the said replacements. Carbonation was carried out naturally in the environment where the concentration of the carbon dioxide gas was at 0.03 per cent, the relative humidity of 65 per cent and the temperature of 27°C for a maximum period of 120 days. Measurement of carbonation depth was taken in accordance to the BS EN 13295: 2004. The carbonation resistance of the concrete was assessed based on the degree of compliance with the common design life requirement of 50 years. The filler effect from the CMS was verified using the capillary absorption test (ASTM C1585: 2013) and the electron microscope.

Experimental concrete specimens containing 5 and 7 per cent of the CMS ash demonstrated better carbonation resistance compared to the control concrete specimens with a minimum attainable design life of 56 years which can reach a maximum of 62 years. Capillary absorption test results indicated that the concrete pores have been effected by the said filler effect and visual observation from the electron microscope confirmed, solidifying the statement.

The CMS ash is proven to contribute to the concrete’s resistance against carbonation. Also, the CMS ash is synthesized from waste materials which have contributed to the application of the green material in the concrete technology.

In today’s scenario, even after achieving ISO certification, quality is still wanting. There is always a gap in people adhering to the standards. The aim of this paper is to discuss the use of neuro linguistic programming (NLP) in aiding total quality management (TQM). 5S and kaizen are identified with lateral thinking tools, using NLP. Case studies on 5S and kaizen applications in civil engineering, with and without the use of NLP, are discussed. The concept of creative kaizen and model Kaizen is introduced for better understanding of the benefits of using NLP. Finally, for the first time, a scientific appraisal of use of NLP for three different civil engineering trades has been attempted and their effects are discussed.

This paper empirically determines the extent to which the criteria of total quality management (TQM) are achieved in ISO 9001 certified small‐ and medium‐sized enterprises (SMEs) in Trinidad and Tobago (T&T). These criteria represent the attributes of TQM and as such one can equate these to the benefits of TQM that are achieved through ISO in SME. In addition, weaknesses are highlighted to which scarce resources could be parsimoniously allocated.

The analytic hierarchy process (AHP) methodology is used to determine the percent weightings of four categories of performance criteria that were identified via a review of quality management literature. These criteria constitute four stages of TQM implementation including top management commitment (TMC), gap analysis (GA), systems deployment (SD) and continual improvement (CI). A process model together with an AHP framework using these categories of criteria is proposed. An empirical analysis of the criteria of each stage using the AHP methodology and the expert opinion of the top management of four SME operating in T&T are used to evaluate the percent weightings of the criteria that are synonymous with TQM implementation

The findings of this study suggest that the SMEs were focused on SD and CI, but were least able to effectively determine their strategic direction. In addition, the potential benefits that could be derived from TQM criteria were lacking in the areas of TMC and GA. Having compliance requirements that deal directly with these areas would help SMEs align their quality management practices with quality culture and strategic process changes towards TQM.

Owing to the ethnographic nature of the study, it was possible to obtain data from only four SMEs.

SMEs in T&T may apply the findings of the empirical research to the design, implementation and CI of their quality management systems (QMSs).

This paper makes a contribution to the body of knowledge in the field of quality management in a region where such work is limited. It also adds value by empirically measuring TQM implementation by determining the extent to which its criteria are implemented in ISO 9001 certified SMEs.

Seismic vulnerability evaluation of various public structures, especially school buildings, is very crucial for designing hazard mitigation initiatives in seismic prone areas. The city of Mymensingh is at great risk of earthquake because of its geographical location, geological structure and proximity to active faults. The city is famous for its ancient and renowned educational institutes that need to be evaluated for understanding the seismic performance of the building during an earthquake. This study aims to evaluate the seismic vulnerability of educational buildings of Mymensingh city using rapid visual screening (RVS) and index based approach.

RVS procedure includes field survey and secondary source assessment for evaluating structural vulnerability attributes. Analytical hierarchy process is applied to develop an index focusing on systematic attributes of vulnerability based on expert opinions. Then, a composite vulnerability map is developed combining both structural and systematic vulnerability score providing an equal weight.

This study evaluates the seismic vulnerability of 458 educational buildings of Mymensingh city and the result shows that 23.14% educational building has high, 46.29% has moderate and 26.86% has moderately low and only 3.71% buildings has the low seismic vulnerability. This study expected to be helpful in resource targeting and prioritizing seismic hazard mitigation activities for education buildings of Mymensingh city.

This study endeavors to present a comprehensive vulnerability assessment method by integrating RVS and index based approach that incorporates both structural and systematic dimensions of vulnerability. The result is expected to be helpful in the formulation of disaster prevention policy for vulnerable educational buildings and development of the earthquake-resistant building codes for the new building construction in Mymensingh city.

Many countries have started to use post-tensioned (PT) concrete because of its sustainability and low cost. However, it is not quite popular in Sri Lanka as the required knowhow and technology are not available within the country. By introducing PT concrete to the country, unwanted costs and time overruns could be eliminated from the construction projects. This paper, therefore, aims to identify the suitability and acceptability of PT concreting for/in Sri Lanka.

An extensive literature review was first carried out to gather knowledge on PT concreting. The four case studies that followed it included eight semi-structured interviews and a document review. Ten expert interviews were conducted finally to strengthen the findings of the literature review and case studies. Cross-case analysis and NVivo 11 content analysis software were used to analyze the data gathered.

Findings reveal that PT concreting saves cost and time of construction and that it can have a control over the resources required for construction, which makes it environment-friendly. PT concreting allows thinner concrete sections, extended spans, stiffer walls that resist lateral loads and stiffer foundations that resist the effects of shrinking and swelling soils.

It is found that PT concreting is more suitable for the construction industry in Sri Lanka than traditional concreting.

Higher education is uncertain which sustainability-related education targets should be sought and monitored. Accepting that something needs to be measurable to be systematically improved, the authors explored how measures relate to potential targets. This paper aims to focus on dispositions to think critically (active open-minded thinking and fair-minded thinking in appraising reasoning) as measures and explored how they related to sustainability concern as an indicative educational target.

This research included the development and testing of research instruments (scales) that explored dispositions to critical thinking and sustainability concern. Authors researched these instruments within their own correspondence groups and tested them with university students and staff in Pakistan, the USA, Austria, India and New Zealand. The authors also asked a range of contextualising questions.

Respondents’ disposition to aspects of active, open-minded thinking and fair-minded thinking do predict their concern about facets of sustainability but their strength of religious belief was an important factor in these relationships and in their measurement.

This research demonstrates the complexity of monitoring dispositions to think critically and sustainability concern in educational systems, particularly in circumstances where the roles of religious beliefs are of interest; and suggests ways to address this complexity.

This research integrates and expands discourses on ESD and on critical thinking in diverse disciplines and cultures. It investigates measurement approaches and targets that could help higher education institutions to educate for sustainable development and to monitor their progress, in ways that are compatible with their culture and values.

This study aims to measure the magnitude of information asymmetry between insiders and outsiders in Indian equity market. The study also investigates the effect of major information sources that affect information asymmetry namely, the informativeness of financial statements, news reports about the company and analyst follow-up.

Six-month profitability of insider trade was used as the proxy to measure information asymmetry. Fama-MacBeth two-stage regression was used to analyse the effect of information sources upon information asymmetry.

The results of the analysis demonstrate that in comparison with findings of similar studies the level of information asymmetry is comparatively high in India. On an average, profitable insider traders in India earn 19.28 per cent return than outside investors. Purchase transactions are more profitable than sales transactions, while the size of company and information asymmetry is associated inversely. Further, news and analyst follow-up are inversely associated with information asymmetry whereas informativeness of financial statements has little effect on information asymmetry.

The study have important insights for corporates in insider information management and legal compliance of insiders’ market activities. Results pointing to the requirements of a deeper Regulatory monitoring and stringent legal framework.

The result validates the concerns of investor protection against informed trade.

The measurement of information asymmetry using profitability of insider trade is novel in Indian context even though the methodology is often used in the literature.

This chapter looks at the way the forces of globalization and, contextual factors together have shaped the trajectory and outcomes of education in the South Asian region which comprises India, Pakistan, Nepal, Bangladesh, Bhutan and Sri Lanka. External influence on the education of this region is not at all a recent phenomenon. The arrival of rulers from Central Asia, the spread of Christianity and Islam through trade connections during the first millennium and finally, the British Colonialism influenced the nature of education in the region historically. The social context, for example, the caste system or discriminatory gender norms also determined the access to education and the ways through which it developed over time.

The asymmetric effect of conservatism on earnings and its other components serves as a contrivance to incorporate transparency and timeliness in financial reporting. This study aims to explore cash flow-return association, which provides insight into the accruals’ contribution that traverses through conservatism-earnings persistence liaison and its associated effects on stock returns.

The study used asymmetric timeliness (AT) model and two firm-year measures, namely, C-Score and conservatism ratio, to capture conservatism. The firm-year measures of conservatism, in addition to the AT measure, facilitate a better understanding of the persistence of reported earnings that branch out the study from the existing literature. Further, the study used panel regression analysis to evaluate the timeliness and persistence of earnings under the conservative approach with a sample of Indian corporate data from 2000 to 2017.

The findings of the study reveal that conservative earnings are less persistent and the accruals recognize bad news timelier than good news. The unfavorable change in earnings shows a lower earnings response coefficient in contrast to favorable earnings variations. However, the appropriate loss recognition nature of conservative reporting has little or no influence on stock returns in an emerging market such as India.

Accounting conservatism is a captivating feature accounting information, especially pertinent to many decision-makers. Thus, the study has implications for the investors while evaluating the adverse and positive changes in accounting earnings; also, the results are helpful for the standard setters in ongoing debate related to accounting conservatism vs fair evaluation. The present study focuses exclusively on ex-post conservatism, while the ex post and ex ante conservatism are having a significant role in accounting practices. Future research on the differential effects of ex post and ex ante conservatism on accounting information in an emerging market, is worth promising.

The study reveals the first Indian evidence on accounting conservatism and earnings persistence relationship, which would bring a different dimension to investors’ perception in evaluating the characteristic variations of reported earnings. The findings add value to the accounting standard setters concerning the asymmetric verification as Indian Accounting standards are on the verge of convergence with International Financial Reporting Standards (IFRS).
