The purpose of the study was to find out the impact of the castrated and intact attribute of the male goat on its price in Pakistan.
Abstract
Purpose
The purpose of the study was to find out the impact of the castrated and intact attribute of the male goat on its price in Pakistan.
Design/methodology/approach
Five major goat markets of Punjab, Pakistan, representing various cropping systems, climatic conditions and socio-economic conditions, were selected for the study. Data about the market location, traits of traded male goat (weight, age, breed, castration, etc.), buyer attributes (education level, experience of buying goats), the purpose of buying and price of 383 traded male goats were collected by using a pretested questionnaire. The hedonic regression model was used to estimate the impact of male goat attributes on its price.
Findings
Results indicated a significant price difference between castrated and intact male goats and recommended castration of male goats for a better price. Additional findings showed a significant positive impact of live weight, age, breed and the selling marketplace on the male goat prices.
Research limitations/implications
By targeting and marketing male goat characteristics like castration, weight, breed and selling markets, goat producers can receive a premium price for their animals.
Originality/value
In livestock markets of developing countries, buyers strongly prefer castrated or intact male goats for several reasons. However, as existing literature did not document the effect of male goat's castrated and intact attribute on its price; therefore, the study is important to fill this gap.

This paper investigates the impact of individualistic (health) and collectivistic considerations (environmental) on the purchasing intention of organic foods.
Abstract
Purpose
This paper investigates the impact of individualistic (health) and collectivistic considerations (environmental) on the purchasing intention of organic foods.
Design/methodology/approach
The study collected 391 responses from service holders of diversified tiers from Bangladesh. It considers two-step structural equation model (SEM), as well as the Ordinal Logistic regression to analyze the fact.
Findings
SEM analysis explores that, both the individualistic and collectivistic considerations affect purchasing intention of organic foods. The regression result finds that income, the number of earning members, occupation, age and BMI are influential determinants of weekly purchasing frequency of organic foods. This research suggests, along with consumer's economic solvency an organized market with dissemination of health and environmental benefits of organic foods acts as a catalyst for purchasing intention of those products.
Research limitations/implications
However, there is still scope of investigating intention-behavior gap between the actual purchasing behavior and purchasing intention, which is not addressed in this study.
Originality/value
To understand the perception of comparatively educated and solvent people toward purchasing intention of organic foods, this research is one of the pioneering attempts in the context of an unorganized organic food market.

Abstract
Purpose
Mobile phone network third-generation (3G) and fourth-generation (4G) modes are the most commonly used modes in many developing countries. This study aims to assess the impact of these network modes and other mobile phone attributes on their retail prices in Pakistan, the fifth most populous and developing country.
Design/methodology/approach
This study has been conducted in Punjab province, which shares about 53% of the Pakistan’s population. Hedonic price analysis was carried out on all new mobile phone attributes sold in Punjab’s markets at the retail level. Various econometric tests, that is, Ramsey regression equation specification error, Breusch–Pagan/Cook–Weisberg and variance inflation factor, were calculated to check the robustness of the results.
Findings
Results of this study indicated that the mobile phone prices were significantly higher for the sets having 4G network mode than the 3G mode. In addition to this, other mobile phone attributes that significantly influenced their prices were brand, weight, camera, random access memory (RAM), memory size, operating system, battery capacity and display size.
Research limitations/implications
This study has implications for mobile phone sales and marketing strategies of the manufacturers, importers, retailers and others involved in the mobile phone business in developing countries like Pakistan. Mobile phone manufacturers/importers can increase their profits by producing/importing the 4G enabled devices.
Originality/value
Although many studies in the literature estimated the implicit price of mobile phone attributes, none of these had explicitly assessed the impact of network mode generation of mobile phones on their prices.

Abstract
Purpose
Curricula is developing from a pure knowledge-based outcome to a more skill-based outcome, with the objective of creating and advancing competencies that meet employer expectations. While the new Sustainable Development Goals (SDGs) demand organisations to change practices and adapt to sustainable goals, there is a lack of understanding in how competencies can enhance these goals. The purpose of this paper is twofold: Study 1 explores competencies related to sustainability required in a work force and examines employer perceptions on the existing literature for competencies. Study 2 empirically tests the influence of sustainability scholarship on non-technical competencies in the work force.
Design/methodology/approach
A mixed method approach was undertaken. A sample of managers from 39 large Australian organisations participated in the scoping study. This was followed by further interviewing executives from 12 multinational corporations in China to assess the validity of competencies and provide deeper understanding of the issues at hand. The quantitative study analysed a sample of executive responses from 229 multinationals in China using factor and regression analysis to test for the effects of mediation.
Findings
The research highlights that the underlying competencies regarding sustainability influences the bigger picture within firms for attaining sustainability. The affective and cognitive growth of sustainability scholarship is governed mainly by a firm’s sustainable values. Core organisational values facilitate the development of non-technical competencies. These relationships and their cumulative effect on competencies provide a theoretical framework for acquiring sustainability within organisations. Employees need sustainability scholarship for enhancing sustainability. Sustainability scholarship reflects high-level learning obtained through universities or training. The research found that non-technical competencies such as professional ethical responsibility mediate between core business competencies and sustainability scholarship.
Originality/value
By exploring employer’s perception of competencies, the study first makes an important contribution in addressing the need to support SDGs by bridging organisational-level competencies and sustainability literacy, which hold significant benefits for practitioners, academia and organisations at large. Second, the theoretical findings strengthen the need for embedding competencies in the curriculum. It conveys the need for sustainability literacy/scholarship to align with organisational training and learning pedagogies, in order to effectively meet industry needs. Third, it provides useful insights on employers’ estimation about workplace competencies and broadens our understanding on the contribution that competencies within organisations make to this end.

Abstract
Purpose
This study aims to investigate the effect of vibration on ceramic tools under dry cutting conditions and find the optimum cutting condition for the hardened steel machining process in a computer numerical control (CNC) lathe machine.
Design/methodology/approach
In this research, an integrated fuzzy TOPSIS-based Taguchi L9 optimization model has been applied for the multi-objective optimization (MOO) of the hard-turning responses. Additionally, the effect of vibration on the ceramic tool wear was investigated using Analysis of Variance (ANOVA) and Fast Fourier Transform (FFT).
Findings
The optimum cutting conditions for the multi-objective responses were obtained at 98 m/min cutting speed, 0.1 mm/rev feed rate and 0.2 mm depth of cut. According to the ANOVA of the input cutting parameters with respect to response variables, feed rate has the most significant impact (53.79%) on the control of response variables. From the vibration analysis, the feed rate, with a contribution of 34.74%, was shown to be the most significant process parameter influencing excessive vibration and consequent tool wear.
Research limitations/implications
The MOO of response parameters at the optimum cutting parameter settings can significantly improve productivity in the dry turning of hardened steel and control over the input process parameters during machining.
Originality/value
Most studies on optimizing responses in dry hard-turning performed in CNC lathe machines are based on single-objective optimization. Additionally, the effect of vibration on the ceramic tool during MOO of hard-turning has not been studied yet.

Abstract
Purpose
The main purpose of this paper is to find out the perception of different respondents' groups related to the factors that influence the online learning for higher education in Bangladesh during the COVID-19 pandemic.
Design/methodology/approach
A survey through a structured questionnaire was conducted to gather qualitative information from the 250 respondents (university students, faculty members and administrative officers) in Bangladesh. A questionnaire has been used for collecting primary data, which have been selected using the justification method under the non-probability sampling technique.
Findings
The findings of this study indicated that majority of the respondents told that online classes could be more challenging than the traditional classroom because of the technological constraints, digital divide, insufficient data pack to access the material to attend the class, poor connectivity, lack of device, poor learning environment, technophobia, delayed response and incapability of the teacher to handle efficiently the material and communication machineries.
Research limitations/implications
Due to time restriction and the COVID-19 pandemic, the study was constrained only to Dhaka region in Bangladesh.
Practical implications
The outcomes of the work can be supportive to the governing bodies and proprietors of the higher schooling organizations who are forecasting to adopt online education as a consistent movement in the future.
Originality/value
At last, based on outcomes, investigators have presented some recommendations that can be taken into consideration at policy level. The study would help universities to comply with the pressing need to impart experiential learning through online education during the COVID-19 pandemic.

Abstract
Purpose
The garment factories focus on improving their production systems by involving innovative and advanced production methods and/or techniques to cope with fast-changing trends. Accordingly, this study aims to establish the standard allowed minutes (SAMs) and sewing efficiencies for Tanzania’s sewing industry, thus improving the production processes.
Design/methodology/approach
The research deployed a quantitative method. A stopwatch measured each operation for shirts and trousers to compute SAMs and efficiency. The shirt manufacturing processes involved 40 operations. Ten measurements were taken from different SL and LL industries operators for each operation. The trouser comprised 42 operations with 10 measurements taken from a different operator at the same garment factories for each operation.
Findings
SAMs for shirts at SL and LL factories were 29 and 31 min, respectively, while trousers were 30 and 34 min. The sewing efficiencies for shirts at both SL and LL factories were 83.98% and 81.93%, respectively. Similarly, the sewing efficiencies for trousers at both SL and LL factories were 81.25% and 80.95%, respectively.
Research limitations/implications
Since SAMs results are not established through literature rather a quantitative approach, the findings thus place crucial information for similar factories to benchmark from. Such information are crucial as factories could increase productivity and operational efficiency, reduce costs and non-value adding activities and estimate lead times. Notwithstanding the findings gathered, the study only established SAMs for two garments.
Originality/value
Although the garment industry has been developing over the years, this study was probably among the first studies in Tanzania that established SAMs. Theoretical underpinnings indicate that the factories use the experience to assemble garments, thus the need for this study.

Abstract
Purpose
The purpose of this paper is to investigate the mediating role of psychological problems (stress, anxiety, depression) between hearing impairment (HI) and tinnitus in tinnitus patients. Sample comprised of 110 patients (male, n=70; female, n=40).
Design/methodology/approach
The purposive sampling technique was used based on correlational design. Two scales, tinnitus handicap inventory developed by Newman et al. (1996), and depression, anxiety and stress scale developed by Lovibond and Lovibond (1995), were employed to assess tinnitus, anxiety, stress and depression among tinnitus patients.
Findings
The study revealed that tinnitus was positively significant correlated with depression (r=0.55, p<0.001), anxiety (r=0.63, p<0.001), stress (r=0.54, p<0.001) and hearing loss (r=0.81, p<0.001). The results also revealed that hearing loss was positively significant predictor for tinnitus (β=20.72, p<0.001). Further, it was revealed that tinnitus was positively significant predicted by anxiety (β=2.62, p<0.001), stress (β=2.33, p<0.001) and depression (β=2.71, p<0.001); the interaction between psychological symptoms and hearing loss was negatively significant predictor for stress (β=−0.51, p<0.001), anxiety (β=−0.57, p<0.001) and depression (β=−0.62, p<0.001). Moreover, it was revealed that female tinnitus patients were more predisposed to stress, anxiety and depression as compared to male tinnitus patients. Results also elaborated that those tinnitus patient who had profound HI were less inclined toward psychological problems as compared to those tinnitus patients who had mild to moderate level of HI. This study would be helpful for the clinical setting to tackle the psychological problems of tinnitus patients.
Research limitations/implications
This study consisted on population from urban cities of Pakistan; therefore, the findings cannot be generalized on overall population. In future, descriptive as well as experimental studies will be beneficial to describe the mechanism of tinnitus across gender in detail. Native tool for measuring gender-related problems would be effective in future as it integrates cultural aspects as well.
Originality/value
There is a consensus across researchers that tinnitus is one of the most important biological problem which initiates various other psychological problem (Minen et al., 2014; Vogel et al., 2014). Numerous studies have been conducted to find out the relationship of tinnitus with various psychological and biological factors (Boi et al., 2012; Li et al., 2014; Marciano et al., 2003; McCormack et al., 2015; Møller et al., 2010; Udupi et al., 2013; Zöger et al., 2006).

Abstract
This article examines the misinformation on the COVID-19 pandemic in social media and electronic media, as well as whether the existing legal administration and laws in Bangladesh, Singapore, and Vietnam are adequate to combat the infodemic. People who believe misinformation and fake news about Coronavirus, prevention, and treatment may put their lives in danger. False information about Coronavirus has spread throughout the world, not just in South and Southeast Asian countries, causing widespread concern in the global healthcare community. We employed a qualitative approach as well as the case study analysis method. Case studies were conducted using news reports and news channels. We examined the legal provisions of the People's Republic of Bangladesh's Constitution, as well as factual analyses of Singapore and Vietnam. We discovered the impact of misinformation dissemination through social and electronic media, which is prevalent not only among rural Bangladeshis but also in almost all classes in Singapore and Vietnam, and how such influence can be detrimental to the interests of Bangladesh, Vietnam, and Singapore.
