Abstract

Purpose

The purpose of this paper is to examine the dynamic relationship between oil exports, non-oil exports, imports and economic growth in the Organization of Petroleum Exporting Countries (OPEC), covering the period 1972-2013 by using panel data analysis.

Design/methodology/approach

The results from the dynamic panel data methods are as follows: there exists the cross-sectional dependence on each variable. According to the cross-sectionally augmented panel unit root tests, all variables are stationary at the first difference. Westerlund and Edgerton (2007) LM Bootstrap cointegration test shows that there is a long-term relationship between variables.

Findings

The results obtained by the Common Correlated Effects (CCE) estimator indicate that the increase in oil exports has a positive impact on the GDP of all countries, while the increase in oil exports has a negative impact on the non-oil exports of some countries.

Originality/value

In this study, the relationship between oil exports, economic growth, imports and non-oil exports of the 12 OPEC member countries is tested by considering the cross-sectional dependence between 1972 and 2013. In the study, the authors found a positive relationship as a result of researching the impact of oil exports on economic growth in the frame of CCE panel estimations results.

Abstract

Purpose

In order to understand interactions aw vs equilibrium moisture content (EMC) in fortified coconut powder, moisture sorption isotherms were constructed under different storage conditions in order to predict the changes in their physical, chemical and microbiological properties that occur during storage and processing, which are unique to each food.

Design/methodology/approach

For which the moisture sorption isotherms were determined at three different temperatures (15, 25 and 35 °C), in a range of water activity from 0.1 to 0.90. Nine models, namely, the GAB, BET, Oswin, Smith, Halsey, Henderson, Chung and Pfost, Peleg and Caurie equations, were fitted to the sorption data. Various statistical tests were adopted as criteria to evaluate the fit performance of the models.

Findings

Of the models tested, the Peleg model gave the best fit to experimental data (R2 = 0.997; RMSE = 0.276), across the full range of water activities and at different temperatures. Humidity of the monolayer (mo) was found between 2.54 and 2.34%, a fundamental parameter to define the storage and control conditions, given that it is considered the value at which the product is more stable. The net sorption isosteric heat (Qst) increased to maximum and then diminished with increased moisture content (Xw); maximum values were obtained in the Xw interval between 0.48 and 2.87% (db), being between 35.72 and 99.26 kJ/mol, where the maximum value indicates coverage of the strongest bond sites and higher adsorbate-adsorbent interaction.

Originality/value

These results provide reliable experimental data on water absorption isotherms of the CP + FAC important to determine optimal processing, storing and packaging conditions.

Abstract

Work and societal values were examined through a 72‐item survey for a sample of nearly six hundred managers, business owners, and professionals in Turkey. Factor analyses revealed eleven work value dimensions and eleven societal value dimensions. A second order factor analysis revealed nine meta‐dimensions among which indigenous concepts of cynical fatalism and under‐ambitious work deserve further attention. Findings also validate comparatively well‐established notions such as paternalism and trust.

Abstract

Purpose

The authors examine whether Turkish fund managers employ liquidity timing along with market return timing, and if additional economic and market factors could affect their timing abilities, to help explain the contradictory results in literature vis-a-vis market timing ability.

Design/methodology/approach

The authors apply panel data analyses, with interaction terms and incorporating structural breaks, to monthly data for 96 out of 131 Turkish variable mutual funds which have available data for the sample period of 2011–2018. The authors employ the Amihud (2002) illiquidity measure to study market liquidity timing ability along with how additional economic and market factors affect this ability.

Findings

The authors find liquidity timing to be the performance enhancing method employed by Turkish variable fund managers in conjunction with market timing and that evidence for market timing may depend on whether structural breaks, that may be present in returns, are incorporated in the analysis. The authors also find that economic, technology and market-related factors affect timing abilities of fund managers.

Research limitations/implications

Conclusions are for Turkey, for the sample period studied, and for the control factors selected based on literature.

Practical implications

It is important to understand the role of market liquidity in making investment decisions and the paper contributes toward an understanding of how managers design their timing strategies in order to enhance portfolio performance, as well as the impact of additional factors on their ability to time market returns and liquidity. This is also important for evaluating fund managers' performance in terms of contribution to portfolio value.

Originality/value

To the authors knowledge this is the first study on Turkish markets to employ liquidity timing in the context of panel data analyses using interaction terms, as well as structural breaks, to distinguish the extent of liquidity timing from return timing, while incorporating the effect of additional factors on timing ability.

Abstract

Purpose

The purpose of this paper is to examine the relationship between the stress experienced by parents during the pandemic and their cyberchondria. The research was carried out in a descriptive and cross-sectional manner.

Design/methodology/approach

The sample of the research: living in Turkey and has created 432 parents with at least one child between the ages of 6 and 15. Participant information form, parental stress scale and cyberchondria scale were used in the study. Data were collected through online surveys between July 1, 2020, and August 31, 2020.

Findings

In the study, when the scores obtained from the Parental Stress Scale and the Cyberchondria Scale were compared with the demographic characteristics, a significant difference was found between gender, age, marital status, education level, economic status, number of children and presence of chronic diseases (p < 0.05). It was determined that there is a significant difference between the responses of the parents regarding the pandemic process and the Parental Stress Scale and the Cyberchondria Scale (p < 0.05). A positive significant correlation was found between the Parental Stress Scale and the total and subdimensions of the Cyberchondria Scale (p < 0.05).

Research limitations/implications

The research was carried out with only parents with children between the ages of 6 and 15, but it reveals the stress and cyberchondria of the parents during the pandemic.

Originality/value

The results obtained reflect the factors affecting the stress and cyberchondria levels experienced by parents during the pandemic process. Also, as the stress of the parent's increases, it has seen that the level of cyberchondria increases in parallel.

Abstract

Purpose

This paper aims to introduce the concept of biomorphism (i.e. indirect experience of nature) in servicescape designs and validates its impact on consumer responses. Using the stimulus-organism-response (S-O-R) framework, this study explores the relationship between biomorphic servicescape designs and the servicescape preference. Further, it explains how biomorphic designs can help users to get better connected with the servicescapes by introducing the mediating role of attention restoration and place identity (emotional and cognitive), as explained by attention restoration theory.

Design/methodology/approach

Two empirical studies were carried out to test the hypothesised relationships: an exploratory pre-experimental design with one-shot treatment using 200 images as stimuli and 3,680 responses; and a 3 × 2 factorial design with three-dimensional images with about 654 responses for three service contexts chosen a priori: fashion retail, restaurant and hospital lobby.

Findings

This study conceptualises the role of biomorphism – elements that mimic natural forms – in servicescape designs and establishes that, akin to natural elements, the indirect experience of nature in servicescapes also has a positive influence on attention restoration, perceived place identity and servicescape preference of the consumers. This implies that the effects similar to that of a biophilic servicescape can be achieved through servicescape elements that mimic natural forms.

Originality/value

Extending the idea of biophilia, this research adopts the concept of biomorphism from architecture and environmental psychology domains and introduces biomorphic servicescape designs, which could be more practical at times compared to biophilic servicescapes. It establishes the influences of biomorphic servicescape designs on consumer preferences. Grounded in the S-O-R model, it further explains this relationship through mediating effects of attention restoration and place identity. Being new to marketing and management domains, this research may trigger a series of research studies on biomorphic service environment designs, with desirable implications for services marketing and services operations functions.

Abstract

Purpose

Rapid technological advancements and the ever-increasing demand for Internet and social networking sites worldwide have increased the opportunity for extensive use and misuse of these platforms. Research and practice have typically focused on the brighter side of social networking sites due to the adoption of EHRM (Electronic Human Resource Management). However, less is known about the dark side of EHRM, especially the drawbacks associated with the use of social networking (SNs) platforms in organisations. In addition, most of such studies have primarily involved the western country context, and in an emerging country scenario, these kinds of studies are limited. Hence, the study aims to investigate the complexities of the use of SNs as an e-HRM strategy in organisations in an emerging country context.

Design/methodology/approach

Drawing on 26 in-depth interviews of HR practitioners and analysing their narratives surrounding employees' use of social networking (both enterprise social networks [ESNs] and social networking sites [SNSs]), this study illuminates the dark or the adverse side of EHRM. Specifically, it focuses on the link between employees' deviant workplace behaviour and their usage of social networking (SN) platforms in organisations (i.e. SNs at workplaces influencing employee's unethical behaviour at work).

Findings

The empirical findings reveal the subtle intentional and unintentional indulgence of employees via SNs in various types of deviant behaviours such as sharing confidential information, bullying, harassment, breaching colleagues' privacy, etc., at the workplace in the emerging market context of India. Utilising the social networking perspective and the 4Ps of deviant theory, this article describes deviance behaviours in detail and explains the inadvertent complexities of leveraging SNs as an EHRM tool at the workplace. These insights then provide a starting point for discussing the theoretical and managerial implications of the research findings.

Research limitations/implications

Derived from the current research, this model offers an integrative frame-work for understanding DWBs in SNs platforms in general. This also shows that use of SNs at workplace often leads the employee engaging in non-productive activity. Hence future studies can explore the application of this framework in organizations in detail, thus further highlighting the usefulness of EHRM to understand the employee behaviours at the workplace by the organisations.

Practical implications

The research offers several managerial implications concerning the use of SNs as EHRM strategy at the workplace, which is perceived as a global challenge nowadays. Primarily it offers suggestions for the social media professionals and HR practitioners regarding the use of SNs in organisations.

Originality/value

The study's findings highlight the complex process that explains how SNs as an EHRM strategy affect employee deviance behaviours in the workplace. Till date, no known study has considered the possible effect of SNs on deviance behavior at the workplace in an emerging country context.

Abstract

Purpose

Workplace loneliness has become a concern in diverse work settings. However, workplace loneliness research is in its early stages of development and not much is known about the effects of it on organizations and its members, especially in police organizations. The purpose of this study is to investigate the relationships between workplace loneliness, anxiety, happiness, task performance, and organizational citizenship behavior (OCB). Data from police officers in Korea were used to test these relationships.

Design/methodology/approach

Using a three-wave time-lagged procedure, the study sample consisted of 227 police officers in South Korea from one regional police headquarters (Yongin Dongbu Police Station) and four substations in the Yongin region. The study tested parallel mediation of anxiety and happiness in the relationships between workplace loneliness and workplace outcomes using the PROCESS macro (Model 4) for SPSS 26.

Findings

The regression analyses with bootstrapping results indicated that police officers' anxiety and happiness served as mediating mechanisms linking workplace loneliness with task performance and OCB.

Originality/value

The police force is a very significant facet within society. However, research has not yet investigated loneliness in the police context. Thus, the study investigated the proximal and distal effects of workplace loneliness by associating workplace loneliness with task performance and OCB via anxiety and happiness.

Abstract

Purpose

E-learning has gained much focus from educators and researchers, with many extolling e-learning over traditional learning. Despite this focus, implementation of e-learning systems often fails. The purpose of this paper is to consider a range of barriers, impacting the success of e-learning implementations, yet to the best of the authors’ knowledge no conceptual framework is able to consolidate existing research.

Design/methodology/approach

This paper undertook an in-depth review of literature concerning e-learning implementation barriers. Papers were extracted from established peer-reviewed journals and open sources. Articles not related to e-learning implementation barriers were discarded. A total of 259 papers were identified, published between 1990 and 2016. Hermeneutics and data-driven qualitative content analysis was used to define 68 unique barriers.

Findings

The 68 unique barriers were thematically grouped into four conceptual categories, i.e. Technology (T), Individual (I), Pedagogy (P), and Enabling Conditions (EC). These four categories led to the conceptualization of “TIPEC” framework, which highlights the key concepts hindering e-learning implementation and delivery. Results show that most articles only consider a narrow range of success barriers.

Practical implications

The proposed TIPEC framework acts as a guide for education practitioners, system developers, policy makers, and researchers. It provides stakeholders with a summary of e-learning barriers.

Originality/value

This paper fulfils an identified need for a conceptual framework that consolidates all current research related to e-learning implementation barriers.

Abstract

Purpose

The purpose of this paper is to investigate and identify the price sensitivity of consumers of three- and five-star hotels and to determine the impact of bundling strategies on consumers’ price sensitivity.

Design/methodology/approach

To calculate price sensitivity, authors apply the van Westendorp’s price sensitivity meter (PSM). To understand the impact of bundling strategies, univariate and bivariate techniques are applied.

Findings

PSM results reveal the optimal prices and the range of acceptable prices for three- and five-star hotel. The bundling strategy results reveal that five-star customers are less sensitive to mixed-leader bundling. Regarding mixed-joint bundling, managers could improve sales through bundling strategies if they selected an attractive service (e.g. restaurants).

Practical implications

Findings assist hotel managers to understand the different price sensitivities, according to the hotel typology. Managers can manage prices without the risk of losing market share or revenue. The results help managers in deciding which bundling strategies they can create, as well as the services to be included to achieve highest profitability.

Originality/value

No research to date to the best of the authors’ knowledge has attempted to understand and compare the role of bundling strategies in three- and five-stars hotels. Moreover, no research has attempted to measure and compare customers’ price sensitivity of three- and five-stars hotels.
