The impact of perceived corporate social responsibility on consumer happiness and brand admiration
Tosun, Petek; Tavşan, Nihat
This study examines the effect of perceived corporate social responsibility (CSR) on consumer happiness and brand admiration as a consequence of consumer happiness. It suggests an original conceptual model that investigates perceived CSR, ethical consumption and hope as antecedents of consumer happiness. Design/methodology/approach: The study followed a quantitative approach. A face-to-face survey was conducted to examine the conceptual model. Data were analyzed with partial least squares structural equation modeling (PLS-SEM). Findings: Hope and perceived CSR significantly influence consumer happiness. Consumer happiness is a significant antecedent of brand admiration. Although consumers' ethical position (idealism and relativism) is linked to ethical consumption, ethical consumption does not influence consumer happiness. Idealism and relativism are insignificant in moderating the perceived CSR–consumer happiness relationship. Practical implications: Brands' CSR actions create a positive atmosphere and contribute to consumer happiness and brand admiration. Managers can emphasize happiness and hope in CSR programs to build stronger consumer relationships. CSR activities can be engaging for consumers regardless of their ethical consumption levels. Originality/value: Although CSR, consumer happiness and their impacts on consumer–brand relationships are crucial, previous studies mainly focused on the organizational perspective and employee emotions regarding CSR. This study focused on consumer happiness in the CSR context and tested a conceptual model that revealed the significant relationships between hope, perceived CSR, consumer happiness and brand admiration. It extended previous findings by showing the direct positive impact of perceived CSR on consumer happiness.

Macroeconomic stability and foreign direct investment
Çakici, S. Meral
This study aims to provide an extensive empirical investigation of the macroeconomic determinants of foreign direct investment. More precisely, influence of macroeconomic stability on foreign direct investment is examined, where macroeconomic stability is defined as composite variables capturing financial, political and price stability. Panel estimation results for 96 countries from 1980 to 2010 show that income and financial openness levels affect foreign direct investment significantly. Estimation results for emerging countries exhibit the key findings, thereby highlight the novel contribution of this study to the literature. It is shown that several components of macroeconomic stability influence foreign direct investment positively significantly.

Numerical study of optical absorption coefficients in Manning-like AlGaAs/GaAs double quantum wells: Effects of doped impurities
Dakhlaoui, Hassen; Belhadj, Walid; Durmuşlar, Aysevil Salman; Ungan F.; Abdelkader A.
We study the electronic and optical properties of a heterostructure based on Manning-like double quantum wells under the impact of an n-doped layer inserted in two different locations. By solving the coupled Schrödinger-Poisson equations, we have determined the four lowest energy levels and their corresponding density of probabilities. After that, we have deduced the optical absorption coefficients between the ground level and each excited state. The study addresses two locations of the doped layer. The first location is at the center of the heterostructure and the second one is at the middle of the right quantum well. The obtained findings show that the energy levels are degenerated when we dope at the center especially for low values of doping concentrations. However, by doping at the right well, we observe a lifting of degeneracy even for low concentrations of the doped layer. Our study demonstrated that the lifting of degeneracy which was absent for low concentrations in the case of doping at the center of the heterostructure can be obtained by adjusting one of the structural parameters of the Manning-like potential. Furthermore, we have discussed in detail the blue and red shifts behaviors observed in the dominant optical absorption coefficients, especially by varying the concentration of the doped layer. Our study confirms that the doping technique stills an excellent strategy to manipulate the electronic and optical properties in quantum wells based on symmetrical shapes.

Application of fuzzy DEMATEL approach in maritime transportation: A risk analysis of anchor loss
Kuzu, Ali Cem
Vessels are exposed to various operational risks throughout their service life. Anchor loss, which is one of the operational risks, may lead to grounding, collision and even total loss of vessel afterwards. Accidents due to loss of anchor may lead to serious consequences such as pollution, injury, loss of life and property. Therefore, it is very important to minimize the risk of anchor loss. In this study, a comprehensive literature review including accident and incident reports, technical reports and expert views was conducted to determine the factors that may cause anchor loss of ships. In order to analyze and define the cause-effect relationship between the determined factors, combination of the fuzzy logic and the DEMATEL (Decision Making Trial and Evaluation Laboratory) method was used. The aim of this study is to mitigate the risk of anchor loss by developing an alternative risk analysis tool. Environmental factors at anchorage area, training and competency of crew, the number of shackles paid out, anchoring method and selection of anchor are identified as the most critical factors for anchor loss. According to the results, a risk analysis model based on cause-effect relationship between the factors has been presented for the shareholders in maritime industry.
