The main goal of this study is to explore the adoption of a design for manufacturing and assembly (DfMA) and building information management (BIM) approach during the whole lifecycle of assets. This approach aims to tackle issues inherent in the design of traditional construction methods, such as low productivity and quality, poor predictability and building performance, and energy use, through the implementation of a BIM library of off-site components. In recent years, a renewed interest has been directed to the attempt to provide solutions to these urgent problems through the adoption of new advancements in technologies. However, while there are studies focussing on a BIM-DfMA approach, there is a lack of research regarding how this approach should be adopted during the whole lifecycle of the assets. Furthermore, to the best of our knowledge, defining an efficient way of developing a component-based BIM object library has not yet been included in any of the available studies. A mixed methodology approach has been used in this research. A conceptual framework was developed as the result of an extensive literature review to investigate new advancements in the AEC sector. Following the literature review, the framework was tested and validated through a case study based on the production and adoption of a BIM library of off-site components at the design stage of an asset. The architecture, engineering, and construction (AEC) industry has recognised the necessity of a new approach that helps to resolve the well-known issues presented in traditional methods of construction. The conceptual framework and case study proposed presents a valuable new method of construction that support the implementation of a BIM and DfMA approach, highlighting their benefits. This framework has been created using many valuable and reliable sources of information. The result of this research supports the idea of a novel new construction method that focuses on a manufacturing-digital-driven industry, with the use of DfMA in a BIM-integrated approach. This novel method will add significance and be beneficial for a wide range of aspects in the construction sector, contributing to the theoretical and practical domain.

This article offers a conceptual framework of Facebook’s sub-platforms: Profiles, Groups, and Pages. We demonstrate the crucially different affordances that these sub-platforms possess, and the various resulting social practices and dynamics that they enable. With mourning and memorialization as a case study, our findings point at emergent practices ranging along a personal-to-public spectrum of communicative functions and media uses: Profiles offer a personal quality, albeit differently for the bereaved’s Profile and the deceased’s Profile; Groups possess a hybrid nature, combining self-expression alongside public aspects, reviving thus premodern bereaved communities; and Pages possess a distinctly public quality, serving as online memorialization centers where the deceased becomes an icon and a resource for mobilizing broad social change. This comparative and integrated approach may be applied productively to other contexts and other social media (sub-)platforms.

The study seeks to examine the approaches taken currently with regard to scholarship on ecclesiology from the patristic era, the medieval era to that of the reformation and beyond. The study evaluates the various ecclesiological approaches of various confessional traditions that have defined ecclesiology over time. In progression, the study examines contextual ecclesiologies with a focus on three specific cultural geographical environments of Africa, Asia, and Latin America. This is because of the significance that these regions play in the current global shift within Christendom. African ecclesiology has been the centre of focus in an attempt to link all the discussed ecclesiologies with the African Christian thought. The study intends to review the Ubuntu concept and to capture the concept of the humanness of people in the African setting. The study intends to expose the gap in the literature demonstrating that the African conceptual framework can indeed be of use in articulating theology relevant to the African world. The study was keen to evaluate the contribution towards the development and construction of an African ecclesiology using the Ubuntu concept as a remedy to solve ecclesiological problems witnessed in Africa.

Lean Tools

Energy cost is significant in many of the manufacturing activities. The efficiency of energy use is quiet low as there are substantial visible and hidden losses. Visible losses can be easily identified and corrective action can be taken. However hidden and indirect losses form a sizeable portion of the losses. Identifying these losses is not easy and requires an integrated approach which includes thorough study of process, operations and their interactions with energy use. Industries across sectors have implemented lean management principles which target various wastes occurring in the plant. This paper discusses case studies which highlight the exploitation of lean tools as a means for unearthing hidden energy saving potential that often go unnoticed. In addition to the energy savings which results in improved profits and competitiveness, the approach also aids the industry to pursue a path of sustainable manufacturing.

Community Of Inquiry Framework

Transitioning from a face-to-face teaching environment to online teaching requires a shift in paradigm by stakeholders involved (i.e., instructors and students). This chapter provides an extensive literature review to help novice online instructors understand the nature of online teaching presence to help position their students towards more active participation. Premised on the Community of Inquiry framework (Garrison, Anderson & Archer, 2000) and constructivism, we highlight a conceptual framework of four iterative processes for developing online teaching presence: preparations for facilitation, designing the facilitation, implementing the facilitation, and assessing the facilitation. Based on this framework, strategies are articulated for overcoming the challenges of online learning through shared stakeholder responsibility.

At Home

There are currently several systems for home automation and energy management available on the market. These systems are intended to reduce the use of energy, while ensuring optimal and customizable comfort conditions. The advances in technology (Internet of Things, sensors, cloud computing, data processing and thermal modelling) and in the design of interfaces should facilitate the adoption of convenient behaviours by final users, thereby producing more sustainable use of energy at home. Conversely, the effectiveness and efficiency of smart home systems for thermo-regulation is a complex activity, requiring the collaboration of multiple stakeholders and experts. In this paper, the authors report a case study about the design of a system for thermal regulation at home developed in a multidisciplinary research team for research and industrial purposes. The paper reports results including: a discussion on a number of issues involved in the design of smart home solutions for sustainability and on the importance of developing an integrated approach to their design; the needs analysis of users and of their functional requirements based on investigation with residents and profiling; final remarks about the role of User Experience Design methods and tools in the development of smart home solutions, understood as socio-technical systems.

Purpose How could a city, a region or a country succeed in its attempt to use sport to (re-)define, position and promote itself? Consequently, what do jurisdictions and brand managers need to consider when using sporting events as a leverage to market themselves abroad? The paper aims to discuss these issues. Design/methodology/approach This paper draws from a combination of an extensive literature review and secondary data collection in order to build a conceptual framework, entitled the “diamond” of place branding through sport. Findings Managers and politicians of cities, regions and countries should espouse a holistic approach when developing their place branding strategy through sport. This holistic approach can be articulated around four dimensions: sport, economic, commercial and social. Research limitations/implications Drawing mainly from a literature review, with the support of concrete examples, this is a first step within the confines of an exploratory research. A future study could analyze the specific cases of jurisdictions and how these fit within the conceptual framework articulated in this paper. Originality/value A place branding strategy through sport should be translated into a socio-economic legacy, with private and public benefits for the community. Ultimately, place branding through sport is one of the components of the overall place branding strategy of a jurisdiction.

To Receive

Mechatronic systems encompass a wide range of disciplines and hence are collaborative in nature. Currently the collaborative development of mechatronic systems is inefficient and error-prone because contemporary design environments do not allow sufficient information flow of design and manufacturing data across the electrical and mechanical domains. Mechatronic systems need to be designed in an integrated fashion allowing designers from both electrical and mechanical engineering domains to receive automated feedback regarding design modifications throughout the design process. Integrated design of mechatronic products can be realized through the integration of mechanical and electrical CAD systems. One approach to achieve this type of integration is through the propagation of constraints. Cross-disciplinary constraints between mechanical and electrical design domains can be classified, represented, modeled, and bi-directionally propagated in order to provide automated feedback to designers of both engineering domains. In this paper, the authors focus on constraint classification and constraint modeling and provide a case study example using a robot arm. The constraint modeling approach presented in this paper represents a blueprint for the actual implementation.

Currently, ACEA utilises biogas obtained from the treatment of the organic fraction of municipal solid waste for thermal and electric energy recovery through endothermic engines (3 MW, in total). By 2020, the biogas produced at the site will no longer be used as a fuel for the combined heat and power units, but it is expected to feed a purification system in order to obtain a flow of biomethane to be injected into the natural gas network. This is part of the Italian strategy to achieve the Horizon 2020 European targets aimed at promoting the renewable production of transport fuels. In order to encourage sustainability and innovative prototype technologies, ACEA has also been involved in some European research projects, in particular for the conversion of biogas into other energy carriers. furthermore, ACEA ha recently built a flexible experimental platform that can used for the validation step of prototypes in an industrial field.

Insight Into

This research provides an assessment tool that assists the selection process of sustainability in detached suburban housing. It investigates the implications of using different design and construction methods including architecturally designed houses, developer housing and prefabricated houses. The study simulates one example of the three types of houses that have been chosen to fulfil a real client brief on a real site on the Sunshine Coast, Queensland Australia. Criteria for sustainability assessment are formulated based on literature reviews, exemplar designs and similar research projects for which the houses can be adequately evaluated. This criterion covers aspects including energy use, materials and thermal performance. The data is collected using computer models and sustainability assessment software to compare and draw conclusions on the success of each house.Our study indicates that architecturally designed housing with prefabricated building techniques are a better alternative to generic developer style housing. Our research provides an insight into the implications of three key elements of sustainability including energy use, materials and thermal performance. Designers, builders, developers and home-buyers are given an insight into some options currently available on the housing market and how the choices made during early design stages can provide a more positive environmental impact.
