This chapter reports on an ethnographic case study of how a group of elementary school teachers designed technology enhanced learning with mobile technology (e.g. notebooks, tablet computers and mobile phones) to facilitate students’ development of literacy and twenty-first century competencies. These teachers designed the school’s literacy pedagogical approach, leveraging the use of technology, namely digital storytelling. The school in this case study is one of the eight Future Schools in Singapore under the FutureSchools@Singapore program. The school has been providing one-to-one mobile computing learning devices and wireless Internet access for its students. The introduction of technology in the classroom makes it possible for twenty-first century competencies to be integrated into literacy development. The conversational framework is used as a framework to examine how the design of the digital storytelling pedagogical approach brings about the various teaching–learning activities – acquisition, inquiry, practice, production, discussion and collaboration. The use of digital storytelling as an approach to integrate information communication technology (ICT) into the classroom has not only modified how ICT is being used in the school, it has redefined how ICT could be used to engage young learners. It has fundamentally transformed conventional storytelling with the use of current state-of-the-shelf (i.e. easily and widely available) technologies. This case study also outlines the processes involved in improving the design of digital storytelling over the years by the teachers. The ecosystem of the school is also taken into consideration and described in detail. Findings suggest the importance of the collaborative efforts of the teachers in the continuous improvements made to this design. The adoption of a learning design framework, such as the one used in this study, can be beneficial to ensure a systematic approach to the design of learning. In addition, the availability of technological infrastructure and computing devices are necessary for the seamless use of technology in the classroom. The just-in-time learning approach is adopted for students to learn technology as they are developing their digital stories.

The purpose of this paper is to examine leading from the middle, which is consistent with calls to distribute leadership, while expanding the direction of influence, from the normal top-down to include a bottom-up or lateral direction. The paper proposes that the position of the vice-principal enables the role incumbent to lead from the middle as a boundary spanner. The research question was what leadership from the middle looks like for vice-principals.

The study consisted of interviews of 28 vice-principals and 10 principals. A mixed case and theme-oriented strategy was adapted, with member checking with each vice-principal.

The findings indicate that in leading from the middle, vice-principals play boundary spanning roles of connecting, translating and brokering: (1) connecting between organisational levels, (2) translating between vision/direction and actualisation, (3) connecting between middle managers and (4) brokering and translating between the ministry and the school.

Leading from the middle is a nascent concept which is worth exploring, given the complexity of educational systems with multiple ecological levels, and the need for leadership to create coherence between the levels.

Gives a bibliographical review of the finite element methods (FEMs) applied for the linear and nonlinear, static and dynamic analyses of basic structural elements from the theoretical as well as practical points of view. The range of applications of FEMs in this area is wide and cannot be presented in a single paper; therefore aims to give the reader an encyclopaedic view on the subject. The bibliography at the end of the paper contains 2,025 references to papers, conference proceedings and theses/dissertations dealing with the analysis of beams, columns, rods, bars, cables, discs, blades, shafts, membranes, plates and shells that were published in 1992‐1995.

We investigate predictive abilities of nonlinear models for stock returns when density forecasts are evaluated and compared instead of the conditional mean point forecasts. The aim of this paper is to show whether the in-sample evidence of strong nonlinearity in mean may be exploited for out-of-sample prediction and whether a nonlinear model may beat the martingale model in out-of-sample prediction. We use the Kullback–Leibler Information Criterion (KLIC) divergence measure to characterize the extent of misspecification of a forecast model. The reality check test of White (2000) using the KLIC as a loss function is conducted to compare the out-of-sample performance of competing conditional mean models. In this framework, the KLIC measures not only model specification error but also parameter estimation error, and thus we treat both types of errors as loss. The conditional mean models we use for the daily closing S&P 500 index returns include the martingale difference, ARMA, STAR, SETAR, artificial neural network, and polynomial models. Our empirical findings suggest the out-of-sample predictive abilities of nonlinear models for stock returns are asymmetric in the sense that the right tails of the return series are predictable via many of the nonlinear models, while we find no such evidence for the left tails or the entire distribution.

Singapore, a multiracial nation, where 80% of the population resides in mid- to high-rise public housing estates, provides an interesting milieu to study neighbouring in the context of high-density living. Its geopolitical position and socio-demographic features – such as an ageing demographic, changing family structure, and increasingly diverse population – have rendered social cohesion an integral aspect of national and neighbourhood-level policies, programmes, and institutions. However, these programmes and policies are built on a relatively static national narrative around mutuality, harmony, and community bonding that rarely takes into consideration current social, temporal, and spatial constructions of neighbouring. It is in this light that we re-examine the social construction of ‘neighbours’ and ‘neighbourliness’ in Singapore using a holistic quality of life (QoL) framework to better understand both institutional and lived forms of neighbourliness. A mixed-methods research approach, comprising 243 semi-structured interviews (161 with a Q method component) and a large-scale survey comprising 3,134 participants, was conducted to explore and assess current norms, attitudes, and practices around neighbouring. Our findings show a dominant set of practices around neighbouring that are polite, minimal, and often referred to as ‘hi/bye’. we note two particular perspectives of the relative importance of neighbours in contributing to QoL and consider the effects of hi/bye neighbouring upon an older group of residents for whom neighbours are still important. This deeper understanding around neighbouring in public housing estates also brings relevant insights to related social cohesion policies and programmes.

The purpose of this paper is twofold: first, to develop a performance evaluation framework for construction and demolition waste management (CDWM); second, to investigate feasible and effective strategies to improve the CDWM performance.

A review of the literature highlighted a lack of comprehensive research to evaluate CDWM performance of key project stakeholders, like owners, contractors and consultants. After the identification of 22 performance variables through a pilot study, a first questionnaire survey was conducted to investigate the views of respondents toward CDWM performance. The 132 responses were analyzed using factor analysis to determine specific CDWM performance factors, which formed a conceptual performance evaluation framework of CDWM. Furthermore, a practical index (PI) was proposed to integrate the feasibility and effectiveness of CDWM strategies. The values of PI were employed to prioritize CDWM strategies from data collected in a second questionnaire survey.

The validated results from factor analysis revealed that the conceptual performance evaluation framework of CDWM consists of six factors; and the attitude toward CDWM emerged as the foremost critical factor. The prioritization of PI values indicated that raising CDWM awareness among construction stakeholders was the most feasible and effective strategy for CDWM.

This CDWM performance evaluation framework is one of the first to holistically evaluate CDWM from key stakeholder perspectives. In addition, the PI firstly enables quantitative integration of the feasibility and effectiveness of CDWM strategies.
