The study aims to explain the relationship between
environmental strategies and sustainability
performance in the context of sustainability
accounting. The research addresses why and how
environmental strategies affect sustainability
performance through accounting information
focusing on environmental priorities and modeling
the transformation process. The hypotheses were
tested using the partial least squares method and
additional analyzes were used for further details.
The findings show that environmental strategies
have a positive relationship with sustainability
performance and that the proposed transformation
model has sufficient goodness fit statistics. It has
been found that the positive impact of strategies on
sustainable development is increased through the
data generated by the environmental accounting
system. This study demonstrates that environmental
strategies are associated with sustainability
performance, which is necessary for the improvement
of corporate performance. In addition, the study
shows significant impacts on management processes
by demonstrating the necessity and potential of
environmental accounting to improve sustainable
development

The Sustainable Supply Chain Management (SSCM) concept, which establishes a balance between economic, social
and environmental dimensions, provides an extremely important conceptual framework for companies. Although not
all of these dimensions have the same significance, researchers mostly focus on economic and environmental aspects.
However, it is very difficult to apply the social dimension in the adoption of SSCM due to the barriers encountered in
SSCM. Based on this, this paper aims to analyze the social barriers and identify the relationship between the barriers
with the help of Fuzzy DEMATEL. In this study, thirteen barriers to analysis have been determined. As a result of the
analysis, the first major barrier is defined as “Stakeholders’ Negative Influence (B12)”, the second barrier as “Lack of
Culture without Engagement and Support (B8)”, and the third one as “Ignoring the Rights of Stakeholders (B13)”. The
barrier having the most impact on other barriers was determined as “Lack of State Support” and the barrier which
was affected most by other barriers is “Low price demand of the community (B6)”.

The increasing internationalization and demands of the global market have put pressure on organizations to equip
their staff with critical competencies. Therefore, the purpose of the study is to identify the core competencies regarded
as essential in entering the senior management positions of the hotel industry. By employing a mixed method of
both quantitative and qualitative techniques, the study was carried out in Turkey. The findings suggest that the
core competencies pertain to the leadership, interpersonal, administrative, and conceptual/creative domains of the
competency domain model.

The consumption function describes the relationship between consumption expenditures and income. As is well known,
the distribution of macroeconomic data such as income and consumption is unequal. Accordingly, estimators derived
from linear models may be inefficient. This study attempted to reach efficient estimators, using gamma distribution,
within the limits of this study. The main purpose of this study is to estimate parameters of mainstream consumption
functions using the panel-data of EU members and negotiating countries. Using data from the World Bank, the European
Union Macroeconomic Database (AMECO), and the Bank of International Settlement (BIS), consumption functions
were estimated by the Generalized Linear Model (GLM) approach. The reliability of the estimators was tested with
the Generalized Moments Method (GMM). Furthermore, the study uses GLM, based on machine learning, to obtain
robust estimators for overfitting. Findings of all three methods are compatible with each other and the “Permanent
Income” hypothesis verified.

The “tip” phenomenon attracts the attention of various disciplines such as economics, sociology and psychology
while it is a voluntary payment added on the service fee. A vast majority of the research on tipping examine the
tipping behavior and motivation of the customers in the light of customer responses. There is a limited number of
studies examining the “tip” phenomenon from an employee perspective. The aim of this study is to determine the
tipping perceptions and beliefs of the employees who communicate face-to-face with customers and work in the
hotel industry in Turkey. Our study reveals the meaning of tipping for hotel employees, the dynamics that determine
the customers’ tipping behavior and the strategies that employees use to get a tip, considering the experience of the
employees who worked/are working in a five-star hotel.

In this study, the performance of the indexes
constructed via fundamental values which are
among the alternative indexing strategies, and the
performance of the capitalization-weighted BIST 100
index are compared. The assets, sales, book value,
operating profit and net profit figures in the financial
statements are used to construct the index/portfolio
according to the fundamental data. In addition to
the indexes based on these data, a composite index
and an equally-weighted index were also created.
The returns of these indices were compared with the
performance of the BIST 100 capitalization-weighted
index through various portfolio performance
measures. Among the indexes constructed through
the fundamental values, the assets, book value,
operating profit, net profit, and the indexes created
by the 5-year averages of these fundamental variables
yield higher returns in the long term than BIST 100
capitalization-weighted index and this excess return
is statistically significant. This result was supported by
the analyses using the Capital Asset Pricing Model
(CAPM) and the Fama-French three factor model. It
was concluded that the indexes (except index created
in accordance with the assets) had significant positive
alpha coefficients. The results show that fundamental
indexing strategies can be considered as an important
investment alternative for the investors and that
these strategies can create value in the long term.

This paper aims to explain the relationship between
organizational cynicism, empowerment and the
individual’s sense of social capital in terms of gender.
In this direction the obtained data were analyzed
by structural equation model. The results indicate
that structural and psychological empowerments
have reducing effect on organizational cynicism,
and social capital has a moderator role between
psychological empowerment and organizational
cynicism for both women and men. However women
with high social capital have a greater reduction of
psychological empowerment on organizational
cynicism than men with high social capital. These
findings offer few recommendations for managers
and employees. Managers to decrease employees’
negative attitudes and to ease cynicism may use
empowerment. However, even employees perceive
as psychologically empowered, managers also should
consider some other individual sources such as social
capital that can buffer or strengthen the cynicism.
Particularly for women employees, managers can
focus more on psychological and social resources in
order to decrease negative work consequences. Such
an investigation is necessary to reveal the predictors
of cynicism as one of the important concept in
organizational behavior and management literature.
It is also valuable to understand the differences
between individuals in terms of cynical behaviours
towards their organizations.

The primary purpose of this paper is to explore the relationship between corporate dividend-payout policy and the
competition in the product market for the listed companies in Turkey using a panel data of non-financial firms over
the period 2007 to 2015. Turkey is an emerging market classified as a French-civil-law country with weak protection
of investors. Using Turkish firms, we analyze the effect of competition on dividend-payout policy, under weak investor
protection. Our results indicate that competition measured by the Herfindahl-Hirschman Index and 5-firm concentration
ratio significantly affects dividend payout. Our findings show that competition in the industry negatively influences
the dividend payout. The results demonstrate that in highly competitive industries, Turkish firms pay lower dividends
than the firms in concentrated industries to remain competitive in the market. Moreover, large profitable firms with
lower investment opportunities and lower tangible assets distribute higher dividends to their shareholders in Turkey.

The purpose of this paper to compare the performances of new factor models with the former models in Turkey. In
that aim, newly proposed q-factor model and Fama-French five factor model are compared with Fama-French three
factor, Carhart four factor and Pástor-Stambaugh factor models. The performance metric is chosen as maximum
squared Sharpe ratio which gives a better understanding in comparison of two or more models accordance to Barillas
and Shanken (2017). As per the measure of maximum squared Sharpe ratio, the q-factor model outperforms of all
between July 2009 and June 2017. After that, Carhart four factor model follows as the second best performing model.
It is considered that this result may be due to the portfolio formation frequency of profitability and momentum factors.
Thus, it can be inferred that the higher the data frequency, the better the explanatory power of the model. Although
Fama-French five factor model is similar to q-factor model, the considerable outperformance of q-factor model can
be attributed to the way of factor construction and calculation. Consequently, it seems as though the performance
of the model is sensitive to the way of factor construction and calculation.

The association between natural resource abundance and economic performance has been the common concern of
economists and political philosophers for centuries. While plenty of resources is a blessing for some countries, others
suffer from the paradox of plenty known as Dutch disease. This study aims to search the interaction between natural
resource rents and the manufacturing exports of the 34 Organization for Economic Co-Operation and Development
(OECD) countries between the years 1990-2015, depending on the technology intensity of sectors using the gravity
model of trade. The findings of the study indicate that there is Dutch disease in all of the classifications of manufacturing
industries. In other words, for the 34 OECD countries, the upsurge in natural resource rents has an impact on the
manufacturing sector’s performance in all subcategories.
