Preparation for a sea voyage is one of the fundamental aspects of navigation. Several complexities are involved during the preparation of the ship for navigation due to the nature of maritime work. At this point, analysing human-related error is of paramount importance to ensure the safety of the ship and the crew. This paper describes the principles of a methodology, namely fuzzy-based shipboard operation human reliability analysis (SOHRA), to quantitatively perform human error assessment through procedures of preparing the ship for navigation. While the SOHRA (a marine-specific HRA approach) quantifies human error, the fuzzy logic deals with ambiguity and vagueness in the human error detection problem. The findings show that the total HEP (Human error probability) is found 1.49E-01 for preparing the ship for navigation. Consequently, the paper provides practical contributions to shore-based safety professionals, ship managers, and masters of the ship since it performs a systematic human reliability assessment and enhances safety control levels in the operational aspect.

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.

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.

Karahasan, Burhan Can
New firms have been regarded as one of the key elements for local development. Existing studies focus on the direct impact of new firms via labour markets and job creation. However, the impact of new firms on regional innovation is less investigated. Our analyses are conducted for a developing country, Turkey. Findings of the study show that new firms are crucial for the regional differences in innovation. Results are robust to spatial dependence, an alternative firm formation measure, various regional controls and endogeneity issues. Additionally, impact of the new firms is spatially non-homogenous reminding the ineffectiveness of one-size-fits-all type policies.
