Fuzzy guided integrative factors-based spectrum decision-making in cognitive radio networks
Authors: Ch Suneetha , S Srinivasa Rao , Ramesh K.S. 
Published: April 2020

PurposeElectronic devices aid communication during new communication phases and the scope of cognitive radio networks has changed communication paradigms through efficient use of spectrums. The communication prototype of cognitive radio networks defines user roles as primary user and secondary user in the context of the spectrum allocation and use. The users who have licensed authority of the spectrum are denoted as primary users, while other eligible users who access the corresponding spectrum are secondary users.Design/methodology/approachThe multiple factors of transmission service quality can have a negative influence due to improper scheduling of spectrum bands between primary users and secondary users. There are considerable contributions in contemporary literature concerning spectrum band scheduling under spectrum sensing. However, the majority of the scheduling models are intended to manage a limited number of transmission service quality factors. Moreover, these service quality factors are functional and derived algorithmically from the current corresponding spectrum. However, there is evidence of credible performance deficiency regarding contemporary spectrum sensing methodsFindingsThis article intends to portray a fuzzy guided integrated factors-based spectrum band sharing within the spectrum used by secondary users. This study attempts to explain the significance of this proposal compared to other contemporary models.Originality/valueThis article intends to portray a fuzzy guided integrated factors-based spectrum band sharing within the spectrum used by secondary users. This study attempts to explain the significance of this proposal compared to other contemporary models.
Market response towards different types of politically connected firms during political events: evidence from Malaysia
Authors: Wong Wai-Yan , Hooy Chee-Wooi 
Published: April 2020

PurposeThis paper investigates the market responses towards four types of politically connected (PCON) firms during two political events – general election and change of leader in Malaysia.Design/methodology/approachThe authors capture the market response using cumulative abnormal return and further test it using regression analysis. The authors use a sample of 376 politically connected (PCON) and non-politically connected (non-PCON) firms from 2002 to 2013.FindingsThe market reacted negatively towards government-linked companies (GLC) during both events, showing that GLCs are negatively perceived by the market during political instability. On the other hand, the reaction of the market towards firms connected by businessmen does not differ from other firms. When compared to the findings of past literature, it shows the decreasing influence that businessmen have over the government leader. In further analysis, this study finds firms that are connected to the incoming government leader recorded a higher CAR as compared to firms connected to the outgoing government leader.Practical implicationsThe authors’ study offers several practical implications. Knowing how the market responds to the different types of political connections might prove beneficial to investors. With this information, investors can recognize stocks with potential returns before the event date and may consider buying or selling them to capture a short-term profit. The authors’ findings may also have important implications for the management of PCON firms in terms of implementing an effective risk management and asset allocation plan to safeguard their value during political events that may disrupt the stability of their firms.Originality/valueThis paper provides an insight on how the markets have a different perception towards different types of politically connected firms during short-run political events. Past studies usually categorize political connection into a single category. With this separation, the authors are able to see how their individual CAR differs from other types of PCON.
A detailed review on non-orthogonal multiple accessbased spatial modulation systems
Authors: Jadhav Kishor Purushottam , Mahor Amita , Bhowmick Anirban , N. Anveshkumar 
Published: April 2020

Purpose
Non-orthogonal multiple access (NOMA) is a much hopeful scheme, which is deployed to enhance the spectral efficiency (SE) significantly, and it also enhances the massive access that has attained substantial concern from industrial and academic domains. However, the deployment of superposition coding (SC) at the receiver side resulted in interference. For reducing this interference, “multi-antenna NOMA” seems to be an emerging solution. Particularly, by using the channel state information at the transmitter, spatial beam forming could be deployed that eliminates the interference in an effective manner.

Design/methodology/approach
This survey analyzes the literature review and diverse techniques regarding the NOMA-based spatial modulation (SM) environment. It reviews a bunch of research papers and states a significant analysis. Initially, the analysis depicts various transmit antenna selection techniques that are contributed in different papers. This survey offers a comprehensive study regarding the chronological review and performance achievements in each contribution. The analytical review also concerns on the amplitude phase modulation (APM) selection schemes adopted in several contributions. Moreover, the objective functions adopted in the reviewed works are also analyzed. Finally, the survey extends with various research issues and its gaps that can be useful for the researchers to promote improved future works on NOMA-based SM.

Findings
This paper contributes to a review related to NOMA-based SM systems. Various techniques and performance measures adopted in each paper are analyzed and described in this survey. More particularly, the selection of transmission antenna and APM are also examined in this review work. Moreover, the defined objective function of each paper is also observed and made a chronological review as well. Finally, the research challenges along with the gaps on NOMA-based SM systems are also elaborated.

Originality/value
This paper presents a brief analysis of NOMA-based SM systems. To the best of the authors’ knowledge, this is the first work that uses NOMA-based SM systems to enhance SE.
Consumer preference for novelty in processed foods: a developing country perspective
Authors: Alphonce Roselyne , Waized Betty Mamuya , Larsen Marianne Nylandsted 
Published: April 2020

PurposeThe paper aims to explore consumer preferences for novel and other quality attributes in processed foods. It focuses on preferences for product origin, certification on food quality and standards and tradeoffs between novelty (fortification and highly processed) and other quality attributes.Design/methodology/approachIn total, 317 consumers were randomly selected at a high-end supermarket and a traditional local market in Dar es Salaam, Tanzania. Stated and revealed preference approaches were used to investigate their preferences for different attributes in processed foods. A hypothetical choice experiment was used to assess consumer preference for six baby food attributes and the tradeoffs between the attributes, while the revealed preference method included questions on consumer's actual processed food purchasing and consumption habits. In addition, consumers were asked a series of hierarchical questions assessing the motivation underpinning their choices for different products attributes.FindingsWhen making choices for processed food attributes, consumers are reluctant to choose novel technologies and have a strong preference for natural, nutritious, tasty and quality processed food attributes. However, they are willing to forego their preference for naturalness and to overcome their reluctance to trying novel technologies when the novelty is embedded with such quality benefits as nutrition, but not so when the embedded benefit is convenience. They are also willing to trade off their preference for nutrition for a sensory taste. This suggests that micronutrient deficiencies can be reduced among women and children under five by employing the appropriate strategies in processed food formulation. Further, the preference for product origin highlights the opportunity for national brands to fill the gap created by the increasing demand for processed foods in Tanzania.Research limitations/implicationsThe study claims a developing country perspective but is only representing consumers in one city in a developing country. However, this study speculates that consumers with representative characteristics in such context are likely to behave the same. Furthermore, although this study controlled for a hypothetical bias, having a hypothetical choice experiment with non-shoppers (non-purchasers) could have triggered the hypothetical bias, making participants concentrate more on non-price than price attributes.Originality/valueThe paper offers a developing country perspective on consumers' preferences for novelty in processed foods and tradeoffs with other quality attributes.

Authors: Komaratat Chankawee , Auemaneekul Naruemon , Kittipichai Wirin 
Published: April 2020

PurposeThe purposes of this paper were to assess the quality of life (QoL) in patients with type II diabetes mellitus (DM) in a suburban tertiary hospital and determine the factors that affect the QoL including individual characteristics, health factors, self-care behaviors and social support.Design/methodology/approachThis study was a cross-sectional study among DM type II cases being treated in a suburban tertiary hospital in Thailand. Data were collected by personal interview from 188 patients in 2018. Diabetes-39 was administered to assess QoL.Findings54.3 percent of patients had good QoL. Total score of QoL was moderate which found an average score of 216.0 ± 41.0, 46.8% had moderate level in self-care behaviors and 56.4 percent had moderate level in social support. The factors associated with QoL in patients were cerebrovascular disease (Fisher = 7.2, p = 0.01), self-care behaviors (rs = 0.191, p = 0.008) and social support (rs = 0.229, p = 0.002).Originality/valueHealth care system ought to develop a policy driven to improve the QoL in DM type II patients by encouraging self-care behaviors and social support for DM type II patients.
The multi-objective supplier selection problem with fuzzy parameters and solving the order allocation problem with coverage
Authors: Khalilzadeh Mohammad , Karami Arya , Hajikhani Alborz 
Published: April 2020

Purpose
This study aims to deal with supplier selection problem. The supplier selection problem has significantly become attractive to researchers and practitioners in recent years. Many real-world supply chain problems are assumed as multiple objectives combinatorial optimization problems.

Design/methodology/approach
In this paper, the authors propose a multi-objective model with fuzzy parameters to select suppliers and allocate orders considering multiple periods, multiple resources, multiple products and two-echelon supply chain. The objective functions consist of total purchase costs, transportation, order and on-time delivery, coverage and the weights of suppliers. Distance-based partial and general coverage of suppliers makes the number of orders of products more realistic. In this model, the weights of suppliers are determined by fuzzy Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method, as a multi-criteria decision analysis method, in the objective function. Also, the authors consider the parameters related to delays as triangular fuzzy numbers.

Findings
A small-sized numerical example is provided to clearly show the proposed model. The exact epsilon constraint method is used to solve this given multi-objective combinatorial optimization problem. Subsequently, the sensitivity analysis is conducted to testify the proposed model. The obtained results demonstrate the validity of the proposed multiple objectives mixed integer mathematical programming model and the efficiency of the solution approach.

Originality/value
In real-life situations, supplier selection parameters are uncertain and incomplete. Hence, the fuzzy set theory is used to tackle uncertainty. In this paper, a multi-objective supplier selection problem is formulated taking into consideration the coverage of suppliers and suppliers’ weights. Integrating coverage of suppliers to select and allocate the order to them can be mentioned as the main contribution of this study. The proposed model considers the delay from suppliers as fuzzy parameters.
Linking authoritarian leadership to employee organizational embeddedness, LMX and performance in a high-power distance culture: a mediation-moderated analysis
Authors: Siddique C. Muhammad , Siddique Hinna Fatima , Siddique Shama Urooj 
Published: April 2020

PurposeThis study has two primary objectives: (1) to shed light on the mechanism by which authoritarian leadership unfolds its impact on such critical aspects of subordinates' work lives as job satisfaction and in-role performance and (2) to identify the moderating conditions which place limits on the impact of authoritarian leadership on work outcomes.Design/methodology/approachData were collected on 552 supervisor-subordinate dyads from the United Arab Emirates. A series of research hypotheses were tested using a mixed-method statistical approach, including CFA and moderated hierarchical regression analysis.FindingsAs predicted, authoritarian leadership exerts negative impact on subordinates' job satisfaction and performance through poor quality LMX and weak employee organizational embeddedness. Both LMX and employee embeddedness mediated the negative relationship between authoritarian leadership and outcome measures while power distance moderated the relationship of authoritarian leadership with LMX and employee organizational embeddedness. Low power distance orientation was found to exacerbate the negative impact of authoritarian leadership on the quality of both LMX relationships and employee embeddedness.Research limitations/implicationsThe study shares limitations of most studies cast in the survey research design.Practical implicationsThe findings underscore the importance of work environment in nurturing high quality LMX relationships and employee organizational embeddedness to buffer the negative effect of authoritarian leadership on subordinates' job satisfaction and performance. In high power distance cultures where workplace inequality is largely rationalized, subordinates who perceive their leaders as authoritarian tend to show low job satisfaction and poor in-role performance. These findings illustrate the importance of management intervention in the early stage of recruitment and selection to attract managers receptive to egalitarian leadership approaches who can equip subordinates with appropriate resources to enhance their job satisfaction and performance outcomes.Originality/valueThe study offers valuable new insights into the mechanism by which authoritarian leadership influences work outcomes in a high-power distance culture. It represents first systematic effort in the Middle Eastern context to identify the conditions that mediate the linkage between authoritarian leadership and work outcomes. The study adds value to the literature by investigating the moderating role of power distance at the individual level of analysis. It detects significant differences in subordinates' perception of power inequality in the workplace in a culture viewed as a high-power distance culture and illustrates how such differences in turn shape the quality of LMX and employee organizational embeddedness.

Empirical evaluation of the antecedents of energy-efficient home appliances: application of extended theory of planned behavior
Authors: Waris Idrees , Ahmed Waqar 
Published: April 2020

PurposeThe purpose of this study is to predict the antecedents of consumers' purchase intention of energy-efficient home appliances. This study incorporated two additional constructs (knowledge of eco-labels and knowledge of eco-labels) in the model of the theory of planned behavior. Consumers' enhanced trust for energy-efficient products is crucial to purchase intention. The second construct is consumers' knowledge of eco-labels. Knowledge of eco-labels would help to assess consumers' tendency toward environmental problems and intention to purchase energy-efficient home appliances.Design/methodology/approachThis study used a quantitative approach using a survey (questionnaire) method to collect data of respondents. Non-probability quota based on age and convenience sampling techniques were employed to select the participants of this study.FindingsThe findings of the study revealed that consumer knowledge of eco-labels, green trust, subjective norm, attitude and perceived behavioral control have positive influence on purchase intention of energy-efficient home appliances.Originality/valueEco-labels are served as a marketing tool to distinguish producer's products from others. Prior studies have only focused on consumers' general knowledge. This study helps marketers to understand and design strategies to generate more value for green consumers. This study also contributes to the literature on green marketing by employing the theory of planned behavior.
An assessment of corporate social responsibility on customer company identification and loyalty in banking industry: a PLS-SEM analysis
Authors: Raza Ali , Rather Raouf Ahmad , Iqbal Muhammad Khalid , Bhutta Umair Saeed 
Published: April 2020

Purpose
This paper aims to address the need for a more in-depth empirical investigation of exploring the link between the adoption of corporate social responsibility (CSR) practices and different aspects of customer behavior in a developing country. This paper develops a research framework and assesses the mediating role of trust, customer-company identification (CCI) and electronic-service quality (E-SQ) between customer perceptions of CSR and customer loyalty.

Design/methodology/approach
Working with a sample of 280 banking customers in Pakistan, partial least square based structural equation modeling is used to test the conceptual model.

Findings
Surprisingly, results suggest that CSR is not directly related to customer loyalty, which is contradictory to previously established findings conducted in developed countries. Thus, confirming a full mediation of CCI, E-SQ and trust in enhancing the effect of CSR on customer loyalty. The study also confirms that CSR is positively related to E-SQ, and E-SQ also directly affects CCI.

Practical implications
Banks should adhere to honest CSR practices and effectively communicate and advertise these practices to increase awareness and knowledge among the customers. Similarly, banks should advance in technological expertise to generate customer identification, which then leads to their loyalty.

Originality/value
Previous studies conferred short-term customer’s reactions, such as purchase intention and brand image. Still, this research discusses the long-term effect of CSR on customer behavior, such as the loyalty of the customers. Moreover, this is the pioneer study that investigates how CSR actions influence customer perceptions about E-SQ and how electronic services affect customer identification with a bank.
Slogans, brands and purchase behaviour of students
Authors: Rybaczewska Maria , Jirapathomsakul Siriphat , Liu Yiduo , Chow Wai Tsing , Nguyen Mai Thanh , Sparks Leigh 
Published: April 2020

Purpose
The purpose of this paper is to extend the understanding of the influence of slogans (e.g. “Dare for More”) on brand awareness and purchase behaviour of students.

Design/methodology/approach
Data were collected thorough 34 in-depth face-to-face interviews with university students, using the customer decision process model as an approach.

Findings
The authors’ research confirmed that conciseness, rhythm and jingle are key features strengthening customers’ recall and recognition, both being moderators of slogans’ power. The role and influence of slogans depend on the stage of the customer decision-making process. Key influencers remain product quality, popularity and price, but appropriate and memorable slogans enhance products’ differentiation and sale.

Practical implications
The authors’ findings deliver a particular justification for marketers not to promise young consumers too much through slogans, as this leads to too high expectations adversely influencing their post-purchase feelings. During the information search, slogans can create or strengthen or weaken the willingness to buy the advertised product, depending on the slogan, thus emphasising the need for care over slogan design and use.

Originality/value
This research expands the understanding of slogans and brand awareness from the perspective of their impact on purchase behaviour. The results revealed that the model approach to shopping behaviour does not confirm the belief that slogans influence consumers the most during the phase of Evaluation of Alternatives. Slogans provide a reference point for young consumers to decide whether they are satisfied or dissatisfied with their purchase during the post-purchase phase and provide information during the information search phase. The authors’ results add to the literature in terms of the criteria determining consumers’ recognition and recall of slogans.
