Multi-objective diagrid façade optimization using differential evolution

Abstract: Facades constitute one of the fundamental systems of contemporary buildings. They serve multiple purposes, such as to ensure proper indoor climate, to provide sufficient daylight, but also to create a desirable architectural image. Integration of these aspects makes facade design a complex task that requires significant effort in order to achieve well-performing results. It is thus desirable that systematic approaches to facade design are developed. In this study, we consider facade design as a multiobjective optimization problem, integrating diverse design criteria, namely indoor daylight distribution, structural performance and cost. We evaluate design performance by making use of simulation. Consequently, we use Differential Evolution (DE) to search for best-tradeoff solutions. We compare the performance of two DE variants, using the Hypervolume metric, and also through qualitative inspection. We report facade designs that demonstrate interesting and often unexpected features, concluding that the proposed approach may lead to a novel, more integrated design process.

An End-to-End Trainable Feature Selection-Forecasting Architecture Targeted at the Internet of Things

Abstract: We develop a novel end-to-end trainable feature selection-forecasting (FSF) architecture for predictive networks targeted at the Internet of Things (IoT). In contrast with the existing filter-based, wrapper-based and embedded feature selection methods, our architecture enables the automatic selection of features dynamically based on feature importance score calculation and gamma-gated feature selection units that are trained jointly and end-to-end with the forecaster. We compare the performance of our FSF architecture on the problem of forecasting IoT device traffic against the following existing (feature selection, forecasting) technique pairs: Autocorrelation Function (ACF), Analysis of Variance (ANOVA), Recurrent Feature Elimination (RFE) and Ridge Regression methods for feature selection, and Linear Regression, Multi-Layer Perceptron (MLP), Long Short Term Memory (LSTM), 1 Dimensional Convolutional Neural Network (1D CNN), Autoregressive Integrated Moving Average (ARIMA), and Logistic Regression for forecasting. We show that our FSF architecture achieves either the best or close to the best performance among all of the competing techniques by virtue of its dynamic, automatic feature selection capability. In addition, we demonstrate that both the training time and the execution time of FSF are reasonable for IoT applications. This work represents a milestone for the development of predictive networks for IoT in smart cities of the near future.

Impact of agri-fresh food supply chain quality practices on organizational sustainability

Abstract: The aim of this paper is to present empirical evidence about the relationship between Agri-fresh Food Supply Chain Quality (AFSCQ) practices and Organizational Sustainability (OS) outcomes. Organizational Sustainability embraces economic, environment and social sustainability. Based on literature review, a set of AFSCQ practices has been identified to create a theoretical model and to setup their relationship to OS as Economic Sustainability (ECS), Social Sustainability (SOS) and Environmental Sustainability (ENS). The measurement scales of AFSCQ practices and measures of OS were established in four stages: initial instrument development; structured interviews and utilization of Q-sort method; wide-ranging data collection by survey questionnaire; and analysis to confirm reliability and validity. Finally, Structural Equation Modeling (SEM) was utilized to validate the model with survey data collected from Indian agri-fresh food industry. The study developed relationships between AFSCQ and OS. Specifically, Customer Focus (CF) and Supplier Management(SM), both have direct and indirect influence on OS while Top Management Leadership and Commitment to AFSCQ, Internal Management(IM) and Supply Chain Integration Management using IT(SCIMIT) have indirect and direct influences on OS, respectively. The results also show that AFSCQ practices should be executed as an integrated coordination instead of independent practices, wherein they co-operate with each other and enrich OS. The empirical outcomes of this paper give evidence to count the AFSCQ as a reliable medium for OS. The AFSCQ practices are favorable to develop organizational sustainability, and then improve economic, social and environmental performance indirectly. The suggested model establishes the relationship between AFSCQ and OS. Additionally, the model’s justification to utilize the Indian agri-fresh food industry gave significant insights both from theoretic and realistic perspectives.

Sürdürülebilir Turizm: Alaçatı Destinasyonuna Yönelik Bir Uygulama

Abstract: Ulkelerin sahip oldugu dogal ve sosyo-kulturel kaynaklar turistleri destinasyona ceken en onemli faktorler olarak kabul edilmektedir. Bu kaynaklarda meydana gelecek tahribatlar kimi zaman geri donusumu olmayan sonuclara neden olmaktadir. Surdurulebilirlik kavraminin destinasyonlar tarafindan anlasilmasi ve alinacak bir takim onemler ile bu tahribatin onune gecilmektedir. Bu calisma Alacati destinasyonunun sahip oldugu turistik cekiciliklerin surdurulebilirliginin irdelenmesi amaci ile yapilmistir. Arastirma nitel veri toplama araclarindan gorusme teknigi ile gerceklestirilmistir. Arastirmada sivil toplum kuruluslari, yerel yonetim ve isletme yoneticileri olmak uzere toplam 15 kisi ile gorusulmustur. Arastirma sonucunda destinasyonun kaynaklarinin surdurulebilirligi icin ozel sektor, kamu sektoru ve sivil toplum kuruluslarinin isbirligi cercevesinde ortak fikir uretip ve uygulamaya gecmesi gerekliligi tespit edilmistir.

An Analysis of Corporate Social Responsibility in the Turkish Business Context

Abstract: Depending on the increasing social and environmental problems, corporate social responsibility (CSR) has been promoted by both national and international bodies to achieve the principles of sustainable development at the organizational level Since the concept has provided a significant framework for the relations between business and society, this corporate response can be particularly crucial for the problems in the developing country context Therefore, it is important to understand how CSR is adopted and practiced by the organizations in such countries to improve the overall quality and quantity of CSR involvement The purpose of current study is to analyse the evolution of CSR conception in Turkey as a developing country Considering its unique position between East and West, Turkey provides a different political, economic, social, and cultural context for CSR conception than other European counties The concept has built on the philanthropic heritage of Ottoman period and then evolved in line with the dependency relationship between business and state during the Republican period Despite the increasing attention of organizations towards CSR during the last decade, it seems that the institutional environment continues to affect the nature and structure of CSR involvement in Turkey
