The Technology of Climate Adaptive Building Shells (CABS) In Improving Environmental & Economic Efficiency

Designing buildings with high environmental and economic efficiency has recently become very difficult, and the ecological problems of the whole world have become realistic and require radical solutions. As 20 - 60% of the total energy used in buildings is affected in their enclosures design and construction, consider adopting sustainable energy efficiency strategies in their design and construction. In the past, factors such as society, economy, and technology influenced architecture, prompting architects to develop innovative design theories, particularly after the industrial revolution and the devastation it left in the environment, such as pollution and natural resource consumption, as well as the phenomenon of heat islands. In addition, many factors such as society, economy, and technology led to the idea of active adaptive smart buildings emerged as these factors have provided technological advances in electrical control systems, computer engineering, information technology, artificial intelligence, electronic science and materials science, opportunities for the use of motor building systems in architecture and its components. Therefore, it introduced the concept of active, interactive, moving and adaptive facades instead of the traditional fixed facades, which are characterised by interacting with the surrounding environment through many technologies that improve the economic and internal environment of the building and its efficiency to make the building sustainable. CABS work with the concepts of adaptability, versatility, and evolution. This paper aims to provide a comprehensive review of the research, design and development efforts in the CABS system field. Based on the study of the theoretical framework, a classification is made to place a variety of concepts in one context. Thus, a measurement ruler is reached that includes an essential vocabulary and indicators that can characterise the CABS so that the research can measure its level of effectiveness in the examples selected. Keywords: adaptive facades, CABS, economic efficiency, environmental efficiency, adaptability, sustainable energy. DOI: 10.7176/JETP/12-2-06 Publication date: July 30th 202

Penile constrictive band injury

Penile strangulation caused by a thread or human hair is an uncommon cause of urethral injury described in paediatric piactice. Five children presented with this entity to the Aga Khan University Hospital, Karachi between August, 1991 and August, 1992. Three children had uneventful recoveries after removal of the contricting agent. Two patients developed urethrocutaneaus fistulae and partial amputation of the penis because of late presentation Early recognition and removal of the constricting agent is necessary to prevent serious complication

How Does Stakeholders Pressure Affect Organization Performance and Employee Wellbeing? Study of Multiple Mediating Roles

Employee satisfaction and high performance is every organization’s goal. When seen through the lens of stakeholder theory, these goals could be achieved by CSR practices through certain ways. Stakeholder theory affords an initial point to assimilate stakeholder pressure and corporate social responsibility practices. This research studies the effect of pressure from stakeholders over organization performance and wellbeing of employees by including the mediating effect of CSR oriented culture, CSR practices, organizational citizenship behavior, organizational commitment, and organizational trust in Pakistan’s banking sector. The study employs quantitative and cross sectional research design. A sample of 180 banks was studied through employing SmartPLS3.0 software using mediation analyses.The findings reveal that CSR oriented culture mediates between stakeholder pressure and CSR practices; CSR practices affect organization performance through organization citizenship behavior. Further, trust is a partial mediator among CSR practices and wellbeing of employees. Serial mediators play their role between stakeholder pressure and organization performance, and also play a role between stakeholder pressure and employee wellbeing. Implications/Originality/Value: The findings suggest Pakistani banks to acknowledge pressure from all stakeholders, and concentrate on CSR practices for their bank performance and staff wellbeing

An Antecedent-Outcome Model Of Responsible Innovation: A Resource-Based Perspective

ABSTRACT Firms are not built in an isolated world, nor can they survive without societal acceptance. Firms are responsible for their actions and innovations, even if those innovations are meant to be "social innovations." Increased awareness of economic and non-economic stakeholders has forced firms to seek social and ethical acceptability to be considered socially and cognitively desirable. It’s no longer about gaining profits only. Firms now need to address the rising concerns regarding upcoming technological innovations, especially artificially intelligent machines. Such technological innovations have serious impacts on human autonomy, fairness, justice, and agency. Collective and responsible stewardship based on some values and principles, through public engagement and informed discourse, may resolve such issues. The research proposes "responsible innovation" (RI) as the solution to all these problems. RI is a novel approach for managing technological innovations that makes the firm ethically, morally, and socially responsible, environmentally friendly, and humanitarian in addition to being business-oriented. Building on the resourcebased view, this study proposes and empirically tests RI as a distinctive competency of the firm developed as a result of its resources (tangible and intangible) and capabilities, leading towards sustainable competitive advantage (SCA) through the contingency effect of absorptive capacity, whereas higher sustainability performance (financial, social, and environmental) became the end result of the SCA gained

An Assessment of the Consumption Function for Iran

In this study, the real private consumption model for Iran was estimated by applying yearly data from 1990 to 2018. The ARDL method is used to assess short-term and long-term relationships between private consumption, labor income, interest rate, wealth, and unemployment rate. According to long-term estimates, income and wealth determine the actual consumption in Iran. However, in the short run, current incomes, wealth, real interest rates, and the unemployment rate are the key determinants of private consumption in Iran. The dynamic of the consumption function shows that all the factors of consumption i.e. real disposable income, wealth, and unemployment rate, real interest rate, have a noteworthy effect on aggregate consumption. The minor and significant coefficient of wealth indicates that the consumption decision is weakly affected by wealth. It provides evidence of the validity of AIH for Iran

An Investigation Of Vibration From Underground Tunnels By Using A Plane-Strain Finite Element Model

In 2013, Qatar Rail announced major rail projects that include an urban rail network for the city of Doha with lines running on the surface and underground which are expected to be in operation by 2020. Railway systems are known as attractive means of transportation that can be implemented to solve traffic problems in urban areas. However, they are associated with noise and vibration that cause disturbance, not only to passengers, but also to occupants of nearby buildings. The purpose of this research is to contribute to the literature by developing an understanding on the dynamic tunnel-soil interaction and the propagation of waves in the ground. In this work, a Finite Element model has been developed that accounts for the specific details of tunnel and ground by a commercial FE software, Abaqus 6-14. The software is used first to model a single isolated tunnel in 2D (plane strain) with point load (corresponding to line load for the 3D case). Then, the software is used to model 3D tunnel under a line load. The results for the 2D and 3D models were found to be matching each other as well as with results from other models reported in the literature. A 2D plane strain model is then developed for a tunnel embedded in a half space and a good agreement was observed when comparing the results with those reported in the literature. Finally, the FE package was used to explore the effect of tunnel shape on the propagation of ground-borne vibration. Several FE models of circular, square, rectangular, and oval tunnels embedded in homogenous soil and multi-layered medium representing Qatar soil were created and analyzed. Changing the tunnel shapes have an influence on vibration measurement in y-direction at frequency higher than 50 Hz for a response point located on the ground surface. Under low frequency (1 Hz to 10 Hz), there is no such difference in vibration for a different twin tunnel shapes embedded in multi-layered soil at a response point located on the ground surface. In general, the numerical results revealed that twin tunnels influence the dynamic tunnel-soil interaction in homogenous and multi-layered soil medium
