Sustainability Principles

INTRODUCTION Sustainability principles have become an integral part of the design and construction process for many new construction projects. The selection of the project delivery method (PDM) is extremely important in the effective execution of the project, and plays a critical role in establishing communication and coordination between the key entities: owner, architect, and contractor. The goal of this paper is to hopefully serve as a starting point for further discussion to improve on the AEC industry's current integration of sustainability principles in PDMs. The first step consists of an assessment of current project delivery systems from a sustainable design perspective. This is followed by a determination of the current limitations, and examination of the various disruptions in the industry. Various literature sources are analyzed to form a framework to discuss improvements and optimization strategies beyond the current system. Thereafter, proposed solutions are introduced at both stakeholders, as well as PDM scales. In this paper, the focus for the conducted analysis and proposed methodologies is predicated on new construction projects instead of retrofits due to the resources available. However, the principles can similarly be applied to retrofit scenarios as well, depending on the specific requirements of the individual project at play.

Persistent failure of construction projects to meet clients’ objectives has compelled a review of the extant systems for project delivery. This study assessed the prospect of adopting Agile Project Management (APM) for construction project delivery in Lagos State. To achieve this, the study examined the level of awareness of APM among construction stakeholders and developed a SWOT model for the adoption of APM technique for construction projects. The research adopted survey method using questionnaire. The study sample involved 196 construction stakeholders. Data obtained were analysed using Mean Score and Fussy Set Theory. The result showed that stakeholders’ level of awareness about the individual methodologies of APM is high. There are also weighty strengths, weaknesses, opportunities and threats in the adoption of APM in construction project delivery. The level of awareness among stakeholders portrays high prospects for APM adoption. However, there is need to embed trust, cooperation and improved team performance.

Building Project

Adaptive reuse of buildings is considered a superior alternative for new construction in terms of sustainability and a disruptive practice in the current capital project delivery model for the renewal of today’s built environment. In comparison to green-field construction projects, adaptive reuse projects require distinct stages, definition of interfaces, decision gates, and planning methods in order to secure the success of the building project. Unfortunately, little research has been done regarding establishing feasible systems for the planning, assessment, and management of adaptive reuse projects, leading to underperforming building projects outcomes. Interface management (IM) can improve renovation projects outcomes by defining appropriate ways to identify, record, monitor, and track project interfaces. IM has the potential of bringing cost and time benefits during adaptive reuse projects execution. The aim of this study is to develop a reference framework for implementing IM for adaptive reuse projects. First, the inefficiencies of redevelopment projects are explained inside of a circular economy (CE) context. Second, an ontology of IM for adaptive reuse projects is defined based on the current barriers to adaptive reuse and the most common interface problems in construction projects. Third, the defined ontology is expanded through a case study by showing examples of adaptive reuse barriers on a case project, and how IM could have been part of the solution for these problems. Finally, this study concludes with the suggestions on interface management systems (IMS) implementation for future adaptive reuse projects.

The current tendering process has vulnerabilities that can be exploited to negatively impact project delivery. There are many research papers that discussed the occurrences of these exploitations (i.e., funds embezzlement, fraud invoicing, etc.), but there has not been one that focused on the study of the tendering process itself, nor presented problem analysis and mitigation options. The aims of this research are to identify and analyze problems in every stage of public tendering process, then offer potential solutions to resolve or curb these problems. In addition to utilizing publicly available studies and interviews were used as starting point of problems identifications. Questionnaires were then distributed to tendering practitioners. Likert scale assessment and factor analysis were used to measure the questionnaires and analyze the data respectively, while proposed solutions were established from experts’ judgement.This study showed that there are 135 problems that occur during tendering process. The most common problem is the bidding system’s inability to provide a complete database of contractors with their personnel, past works and experiences, and performance evaluation. The limited human resources in both number and competency is another important issue to consider. Proposed solution to solve these issues are based on four pillars of reformation concept done by public procurement agency.

Abstract: Solidarity in the classic sense pertains to a cohesion among humans that entails physical contact, shared emotions, and common goals or projects. Characteristic cases are to be found among families, close friends, or co-workers. The present paper, in contrast, treats a phenomenon of the solidarity of distance, a solidarity based in fear of certain others and in incompetence to interact with them. The starting point for this analysis is the person who is motivated to interact with others who are unfamiliar or fear-provoking. Given that the fear and momentary social incompetence do not allow a full interaction to ensue, the individual will move toward solidarity with those others on a symbolic level. In this manner the motivation to approach the others is acted upon while physical and emotional distance is retained.

Two recent debut novels, Songeziwe Mahlangu’s Penumbra (2013) and Masande Ntshanga’s The Reactive (2014), reflect the experience of impasse, stasis, and arrested development experienced by many in South Africa. This chapter uses these novels as the starting point for a discussion of writing by young black writers in general, and as representative examples of the treatment of ‘waithood’ in contemporary writing. It considers (spatial and temporal) theorisations of anxiety, discerns recursive investments in past experiences of hope (invoking Jennifer Wenzel’s work to consider the afterlives of anti-colonial prophecy), assesses the usefulness of Giorgio Agamben’s elaboration of the ancient Greek understanding of stasis as civil war, and asks how these works’ elaboration of stasis might be understood in relation to Wendy Brown’s discussion of the eclipsing of the individual subject of political rights by the neoliberal subject whose very life is framed by its potential to be understood as capital.

Multiple sustainability standards and rating systems have been developed to draw attention to constructing sustainable buildings. The Pearl Rating System (PRS) is a mandate for all new construction projects in Abu Dhabi. Hence, it is important to understand the main components, advantages, and limitations of the PRS. The feasibility and the practical relevance of the PRS are still being studied. This paper addresses this gap and critically evaluates the PRS against some of the well-established rating systems like LEED and BREEAM. The analysis suggests that the PRS considers the cultural aspect of sustainability, in addition to the environmental, societal, and economic aspects. It was also found that most rating systems, including the PRS, have a very superficial inclusion of life cycle assessment (LCA). The paper finally concludes with other observations and outlook for a more robust implementation of the PRS.

AbstractThis article argues that constructions of social phenomena in social policy and welfare scholarship think about the subjects and objects of welfare practice in essentialising ways, with negativistic effects for practitioners working in ‘regulatory’ contexts such as housing and homelessness practice. It builds into debates about power, agency, social policy and welfare by bringing psychosocial and feminist theorisations of relationality to practice research. It claims that relational approaches provide a starting point for the analysis of empirical practice data, by working through the relationship between the individual and the social via an ontological unpicking and revisioning of practitioners' social worlds.

Forms Of Violence

How much violence can a society expect its members to accept? A comparison between the language theories of Julia Kristeva and Jacques Lacan is the starting point for answering this question. A look at the early stages of language acquisition exposes the sacrificial logic of patriarchal society. Are those forces that restrict the individual to be conceived in a martial imagery of castration or is it possible that an existing society critically questions those points of socialization that leave their members in a state of homelessness? The following considerations should help to distinguish between unavoidable and avoidable forms of violence.

Metallothioneins (MTs) are characterized by their high metal loading capacity, small molecular weight, and abundant cysteine residues. It has long been thought that metal-free, or apo-MT peptides were unstructured and only adopted as a distinct conformation upon forming the metal clusters, described as metal-induced folding. More recent studies have suggested that the presence of a globular, yet loosely defined structure actually exists that can be disrupted or unfolded. Residue modification and ion-mobility ESI (IM-ESI)-MS have been used to examine this unusual unfolding process. The structure of apo-MT plays a critical role as the starting point in the flexible metalation pathways that can accommodate numerous soft metals. ESI-MS measurements of the product species formed following the cysteine alkylation of the isolated domain fragments of recombinant human apo-MT 1A with n-ethylmaleimide (NEM) were used in the present study to monitor the denaturant- and heat-induced unfolding at physiological pH. The results indicate that these apo-MT fragments adopt distinct structures at neutral pH that react co-operatively with NEM when folded and non-cooperatively when heated or exposed to high concentrations of the denaturant guanidinium chloride (GdmCl). From these studies, we can conclude that at neutral pH, the domain fragments are folded into globular structures where some of the free cysteine residues are buried within the core and are stabilized by hydrogen bonds. Metalation therefore, must take place from the folded conformation.

Practical Implications

Purpose Considering working in the digital age, questions on the consequences for the individual workers are, so far, often neglected. The purpose of this paper is to deal with the question of whether the digital competences of the workforce is a research topic. The authors argue for the thesis that it is indeed a research topic. Design/methodology/approach In addition to a literature analysis of the top IS, HR, and learning publications, non-scientific sources, as well as the opinions of the authors, are included. The authors’ thesis is challenged through a debate of corresponding pros and cons. Findings The definition of digital competences lacks scientific depth. Focussing on the workforce is valid, as a “lifelong” perspective is not mandatory for research. Digital competence research is a multidisciplinary task to which the IS field can make a valuable contribution. Research limitations/implications Although relevant references are included, some aspects are mainly driven by the opinions of the authors. The theoretical implications encompass a call for a scientific definition of digital competences. Furthermore, scholars should focus on the competences of the workforce, including occupations, roles, or industries. The authors conclude by providing a first proposal of a research agenda. Practical implications The practical implications include the alignment of multiple stakeholders for the design of “digital” curricula and the integration by HR departments of the construct of digital competences, e.g. for compensation matters and job requirements. Originality/value This paper is one of very few contributions in the area of the digital competences of the workforce, and it presents a starting point for future research activities.
