The purpose of this paper is to initially perform Senti-WordNet (SWN)- and point wise mutual information (PMI)-based polarity computation and based polarity updation. When the SWN polarity and polarity mismatched, the vote flipping algorithm (VFA) is employed.

Recently, in domains like social media(SM), healthcare, hotel, car, product data, etc., research on sentiment analysis (SA) has massively increased. In addition, there is no approach for analyzing the positive or negative orientations of every single aspect in a document (a tweet, a review, as well as a piece of news, among others). For SA as well as polarity classification, several researchers have used SWN as a lexical resource. Nevertheless, these lexicons show lower-level performance for sentiment classification (SC) than domain-specific lexicons (DSL). Likewise, in some scenarios, the same term is utilized differently between domain and general knowledge lexicons. While concerning different domains, most words have one sentiment class in SWN, and in the annotated data set, their occurrence signifies a strong inclination with the other sentiment class. Hence, this paper chiefly concentrates on the drawbacks of adapting domain-dependent sentiment lexicon (DDSL) from a collection of labeled user reviews and domain-independent lexicon (DIL) for proposing a framework centered on the information theory that could predict the correct polarity of the words (positive, neutral and negative). The proposed work initially performs SWN- and PMI-based polarity computation and based polarity updation. When the SWN polarity and polarity mismatched, the vote flipping algorithm (VFA) is employed. Finally, the predicted polarity is inputted to the mtf-idf-based SVM-NN classifier for the SC of reviews. The outcomes are examined and contrasted to the other existing techniques to verify that the proposed work has predicted the class of the reviews more effectually for different datasets.

This study aims to develop sweet chestnut incorporated corn-based extrudates by the optimization of process conditions.

The independent process variables for extrusion (blend ratio, barrel temperature, screw speed and feed moisture) were investigated to govern their impact on reliant variables, namely, bulk density, specific mechanical energy, water absorption index, water solubility index, color and hardness. Product and system responses were significantly (p < 0.05) affected by the independent variables. Experimental design with quadratic models experienced a high coefficient of determination (R² = 0.99).

Numerical optimization for the development of extrudates resulted in optimum conditions having corn flour: sweet chestnut flour (80:20), barrel temperature (120°C), screw speed (340 rpm) and feed moisture (12%). Fat, moisture and protein contents of the developed extrudates using optimum conditions were significantly (p < 0.05) lower compared to raw materials – corn and sweet chestnut. The packaging of extrudates in aluminum laminates revealed shelf stability of three months at room temperature without deterioration of quality.

Nutritionally rich sweet chestnut extruded products would be an exclusive option to already existing snacks in the market and can facilitate a new sphere in extruded product sector.

The purpose of this study was to formulate a complete protein food from lentil flour (LF) and egg powder (EP) through microwave-assisted extrusion technology.

In the first part of the hybrid technology, the feed proportion and extrusion conditions were optimized through design expert using central composite rotatable design. In the second part of hybrid technology, the optimized protein pellets (PP) obtained were subjected to microwave heating (MH) for 50,100, 150, 200 and 250 s.

The optimum predicted conditions for development of pellets using extrusion cooking were feed proportion (85% LF and 15% EP), barrel temperature (140°C), screw speed (340 rpm) and feed moisture content (12%). When these pellets were subjected to MH, 150 s of heating time was considered as prudential to induce desirable quality changes in PP. The increase in sectional expansion index, crispness and overall acceptability from 0.637 to 0.659, 4.51 to 6.1 and 3.27 to 3.59 with corresponding decrease in bulk density and breaking strength from 73.33 to 69.75 kg/cm³ and 6.24 to 5.13 N during 150 s of MH indicated that quality characteristics of extruded PPs were improved after MH.

Nowadays, consumers have become more health conscious than ever, and the demand for nutritious snacks has increased many folds. However, the high protein content restricts expansion of snacks, which was overcome by subjecting extruded pellets to MH to produce third generation pellets. Furthermore, the PP has a protein content of 31.62%, which indicates that if an average person consumes 100 g of these snacks, it will suffice 60% of total recommended dietary intake (0.75 g/kg body weight/day). Lentil-based pellets expanded by use of such hybrid technology (microwave-assisted extrusion cooking) can help to provide a feasible, low cost and protein-rich diet for malnourished population besides being a value addition to lentils.

LF in combination with EP was tested for the first time for development of nutrient dense pellets. Moreover, use of microwave-assisted extrusion cooking offers a workable and innovative technique of developing protein-rich pellets with improved physico-chemical and sensory attributes.

Although common throughout the world, little is known about the mechanism by which nepotism is associated with employee outcomes. Drawing from social exchange theory, this study examines whether fear-based silence mediates the relationship between nepotism with employee workplace withdrawal and career satisfaction. In addition, whether gender moderates the relationship between nepotism and fear-based silence is also examined.

Two time-lagged surveys of 330 employees in the Indian banking sector were completed.

As hypothesized, nepotism was positively related to fear-based silence and employee workplace withdrawal; it was negatively related to career satisfaction. Fear-based silence partially mediated the relationships of nepotism with workplace withdraw and career satisfaction. Gender moderated the relationship between nepotism and fear-based silence.

This study shows the negative impact of nepotism on employee outcomes and suggests means for reducing its prevalence in organizations.

This is the first study to examine fear-based silence as a mediator of nepotism’s relationship with employee workplace withdrawal and career satisfaction. It also answers repeated calls for more research on fear-based silence and its antecedents.

Elder mistreatment (EM) is a complex, universal health and social problem predominantly studied in the indigenous (white) populations of Western countries. This has led to consideration of dominant explanations as universal, potentially masking crucial cultural and ethnic differences. This study aims to fill the gap in elder mistreatment literature for the Pakistani community, offering unique perspectives to inform culturally sensitive policy recommendations.

A qualitative approach, anchored in the philosophical basis of constructivist grounded theory, was used to investigate understandings of EM among Pakistanis in Sheffield, UK. This involved two gender-based focus groups (male = 1; female = 1) and 22 in-depth individual interviews, engaging a diverse participant pool, including older people, family caregivers and community stakeholders.

This study reveals diverse understandings of elder mistreatment (EM) among Pakistani adults, varying across age and gender groups, with distinguished key forms identified. Reporting EM is crucial, but victims face complex decision-making, hindered by societal and individual barriers, including moral and cultural dilemmas. Access to formal support is limited, emphasising the need for targeted interventions.

To the best of the authors’ knowledge, this study is the first to delve into the perspectives of Pakistanis on elder mistreatment. It emphasises the importance of policymakers and service providers integrating considerations of race, ethnicity, culture and gender to develop inclusive services, as indicated by the study’s findings.

This study aims to examine a proposed model based on a combination of relationship marketing and service quality dimensions as a significant predictor of corporate image. More importantly, it attempts to identify whether corporate reputation mediates the relationship between and customer loyalty and corporate image in the takāful (Islamic insurance) context, from the viewpoint of Saudi Arabian customers.

An online survey was conducted through an adopted questionnaire from 362 family takāful policyholders from Saudi Arabia. Also, structural equation modelling was used to test the proposed model on the direct relationships of the related constructs, as well as the establishment of corporate reputation as a mediator concerning its relationship between corporate image and customer loyalty.

This study discovered that only two dimensions of service quality (i.e. reliability and assurance) and three aspects of relationship marketing (i.e. Islamic ethical behaviour, financial and structural bonds) have a significant impact on the corporate image of the takāful providers. This study further concluded that corporate reputation mediates the relationship between corporate image and customer loyalty.

This study has presented and tested the perceived service quality using the PAKSERV model in the takāful (Islamic insurance) industry, particularly in the Saudi Arabian context. This research identified the dimensions of PAKSERV (i.e. reliability and assurance) that influence the corporate image and simultaneously, the aspects of relationship marketing (i.e. Islamic ethical behaviour, financial and structural bonds) are also connected to the corporate image. Corporate reputation acts as a mediator between the relationship of corporate image and customer loyalty. This study, nevertheless, only focused in the takāful industry alone, and these findings could also be tested for its validity to different services in other potential studies because of the diversity of the service industry.

The findings of this study highlight the specific components of PAKSERV measures in influencing the corporate image. Furthermore, relationship marketing addressing Islamic ethical behaviour, as well as the three facets of bonding – structural, financial and social bonds are also incorporated and connected to corporate image. Hence, this study will increase the understanding of the impact of service quality concerning the PAKSERV model and relationship marketing on corporate image, reputation and customer loyalty of the takāful operators in Saudi Arabia.

This paper aims to find empirical evidence of bank ownership structures on bank reputation through the mediating role of sustainability reporting (SR) in Indonesian banking sector.

This paper uses purposive sampling to obtain 279 observations from 43 listed banks in Indonesia Stock Exchange during 2012–2018. This study uses structure equation modelling analysis in the AMOS software and intervening test from the Sobel test to investigate the direct and indirect effect in this research model.

The empirical results evidence: foreign, government and public ownership exhibit significant positive effect on SR but not with family ownership; SR positively affects bank reputation; SR appears as a mediator in which foreign, government and public ownership have a positive effect on the bank reputation through the indirect effect of SR while family ownership exhibits insignificant result.

The practical contribution of this study is that SR is proven to increase bank reputation through the legitimation from the public, so the management must properly pay attention by publishing this report.

This study provides several novelties to the literature: SR is used as a mediator in the relationships between bank ownership and reputation in which there is very limited studies investigating these aspects, especially in Indonesia. In addition, most SR studies in Indonesia still focus on SR determinants rather than its impact; customer deposits are used as a measurement basis of the bank reputation as it reflects better the trust and perception of the market so that it is relevant with the reputation level.
