This study examines the osteoconductive and healing capabilities of locally implanted synthetic hydroxyapatite (sHAp) derived from eggshells in the central incisor sockets of rats.
Abstract
Purpose
This study examines the osteoconductive and healing capabilities of locally implanted synthetic hydroxyapatite (sHAp) derived from eggshells in the central incisor sockets of rats.
Design/methodology/approach
Toxicity experiments were conducted in vitro and in vivo, to testify the safety dosage of sHAp. Around 24 mature male Sprague–Dawley (SD) rats had their upper central incisors extracted. The rats were placed into three groups of eight rats each: Group 1: the sockets of extracted central incisors were left unfilled (control), Group 2: filled up with commercially available hydroxyapatite (HAp) and Group 3: implanted with sHAp locally retrieved from eggshells. After extraction, four rats from each group were sacrificed at 2nd and 4th weeks. Maxillary tissue sections were obtained and stained with hematoxylin and eosin (H&E) and Masson’s trichome (MT) staining. Anti-osteocalcin (OCN) and proliferating cell nuclear antigen (PCNA) were used primary antibodies for immunohistochemistry (IHC) special labeling.
Findings
The results showed that the locally implanted sHAp was non-toxic and safe in cell lines (human osteoblast and fibroblast) and animals. Histological analysis of H&E, MT and IHC showed that the sockets treated with locally implanted sHAp from eggshells were filled with new bone tissue of comparable thickness to other groups.
Originality/value
This unique technique uses locally implanted eggshell-derived sHAp with osteoconductive characteristics. In an in vivo model, sHAps increased OCN and PCNA expression to improve bone repair.

Abstract
Purpose
This study examines the relationship between partners' locus of control and their spouses' domains of job satisfaction (job satisfaction and its domains, personal income and promotion) among Australian couples.
Design/methodology/approach
Data were obtained from the Household, Income and Labor Dynamics of Australia (HILDA) Survey. Various estimation strategies including ordinary least squares (OLS), Mundlak approach and instrumental variable (IV) method are used to reveal the relationship between spouse's locus of control and domains of job satisfaction.
Findings
To reduce sex heterogeneity, the analysis used in this study is disaggregated by sex. In particular, the findings of this study show that wives' locus of control positively influences husbands' satisfaction with pay and working hours, while there is no relationship between husbands' locus of control and wives' domains of job satisfaction.
Social implications
The study's findings emphasize the importance of locus of control in couples. A good work–life balance and a healthy marital relationship potentially facilitate positive effects of characteristics from the partner on employees' job satisfaction. Thus, on the organizational level, employers may consider creating a working environment that promotes a healthy marital relationship for their staff, including flexible working schedules, work from home options, family days or family-extended staff events.
Originality/value
This study is the first to reveal the relationship between spousal locus of control and domains of job satisfaction, enriching the current literature on this topic.

Abstract
Purpose
Work-family conflict is an important topic which had an evolution, starting from a static definition, where work and family domains were divided, to a more dynamic and complex balance. COVID-19 has influenced society and created a significant distress among families and working activity, and this topic has been characterised by a major interest, considering some old definitions where this balance was considered problematic but not as an enriching opportunity.
Design/methodology/approach
The authors used SCOPUS to find all records mentioning work-family conflict, by considering book, article and review, excluding conference paper and considering only records written in English language. After a duplicated and not pertinent record removal, the authors obtained a number of 675 records. The authors considered 437 records from SCOPUS to create a cluster map.
Findings
Using SCOPUS and VOSviewer the authors have clustered 5 different areas, which are regrouped in next clusters considering keywords with most co-occurrence and significancy: Work-life balance and burnout gender cluster job stress and performance social and family support job satisfaction.
Research limitations/implications
Cluster map is origined only by SCOPUS database.
Originality/value
This work aims to find a state of art about this topic, creating hypothesis where this problem has been exacerbated by 2020 due to important society modifications created by COVID-19, where recent evolution of work-family balance has been complicated by papers which come back to consider this balance as problematic.

Abstract
Purpose
This study aims to access, analyze and highlight opportunities and problems of the Indian pharmaceutical sector in the broader national health-care industry. The recent changes in the field, at the institutional and corporate levels, have placed India in the spotlight of the global pharmaceutical market, but several threats and weaknesses could limit this expansion.
Design/methodology/approach
Descriptive and inferential analyses have been based on empirical data extracted from authenticated data sources. Subsequently, a narrative strengths, weaknesses, opportunities and threats analysis was performed based on the results of prior investigations and on qualitative data that were retrieved from a marketing intelligence examination to generate an overall scenario analysis.
Findings
Indian pharmaceutical companies have faced several challenges on various fronts. In the home market, drug prices are controlled by the drug price control order; therefore, there is strong pressure on revenues and subsequently on costs. In the international market, threats derived from pharmaceutical multinational companies are emerging as tough obstacles to overcome.
Practical implications
More focus on patents for innovative drugs is required, instead of concentrating primarily on generic drugs. There is a need for policymakers to work on the sustainability and development of the industry, while the companies must redesign their orientation toward enhancing innovation capabilities. In addition, at the level of corporate strategy, firms should establish collaborations and alliances and expand their industrial marketing vision.
Originality/value
This study provides a global overview of the potential growth and development of the Indian pharmaceutical sector, comparing it with internal trends and external competition. The most relevant contribution of the research relies on the shift to innovative production that Indian companies must adopt (after years of focusing only on generic drugs), and in this vein, appropriate industrial marketing solutions are indispensable.

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.

The purpose of this paper is to explore how sustainability reporting is shaped by the global influences and particular national context where businesses operate.
Abstract
Purpose
The purpose of this paper is to explore how sustainability reporting is shaped by the global influences and particular national context where businesses operate.
Design/methodology/approach
The paper uses both content analysis of published sustainability information and semi-structured interviews with corporate managers to explore how sustainability reporting is used to address unique social and environmental challenges in a developing country – Sri Lanka. The use of integrative social contracts theory in investigating sustainability reporting offers novel insights into understanding the drivers for sustainability reporting practices in this particular country.
Findings
The findings reveal that managers’ perceptions about usefulness of sustainability reporting, local contextual challenges and global norms influence the extent to which companies engage in sustainability reporting and the nature of sustainability information reported. In particular, Sri Lankan company managers strive to undertake sustainability projects that are beneficial not only to their companies but also to the development of the country. However, while company managers in Sri Lanka are keen to undertake sustainability reporting, they face different tensions/expectations between global expectations and local contextual factors when undertaking sustainability projects and reporting. This is also showcased in what is ultimately reported in company annual reports, where some aspects of sustainability, e.g. social, tend to focus more on addressing local concerns whereas other disclosures are on issues that may be relevant across many contexts.
Research limitations/implications
Important insights for government and other regulatory authorities can be drawn from the findings of this study. By capitalising on the strong sense of moral duty felt by company managers, policymakers can involve the business sector more to mitigate the social and environmental issues prevalent in Sri Lanka. The findings can also be used by other developing countries to enable pathways to engage with the corporate sector to contribute to national development agendas through their sustainability initiatives and projects.
Originality/value
While the usual understanding of developing country’s company managers is that they try to follow global trends, in Sri Lanka, this research shows how managers are trying to align their responsibilities at a national level with global principles regarding sustainability reporting. Therefore, this paper highlights how both hypernorms and microsocial rules can interact to define how company managers undertake sustainability reporting in a developing country.

Abstract
Purpose
The purpose of this paper is to examine millennial customer perceptions of food trucks and to identify factors that can foster their behavioral intentions pertaining to food trucks.
Design/methodology/approach
The study is based on a sample of 247 millennial customers of various food truck vendors in the United States and was assessed using ordinary least squares regression analysis.
Findings
Food truck image and employee friendliness were found to impact both customer satisfaction and word of mouth behavior; however, the other hypotheses were not supported.
Research limitations/implications
There were two limitations. The first was that one of the constructs did not achieve the minimum average variance extracted. The second was that data collection was done in a single city in the United States; therefore, future research could overcome these limitations through a refinement of the construct’s items and targeting more cities.
Originality/value
There has been limited academic research on the millennial customer perceptions of the food truck phenomenon. This research addresses that gap through a field study that examines factors that contributed to the growth and popularity of food trucks among millennials

Abstract
Purpose
The ketogenic diet (KD) has gained popularity due to its ability to improve type 2 diabetes, weight loss, antioxidant and anti-inflammatory activity. However, long-term use of the KD might not be safe due to its adverse effects. This study examined the effects of the KD alone or in combination with Zamzam water (holy water for Muslims) on glucose homeostasis, lipid parameters and oxidant-antioxidant variables in rats.
Design/methodology/approach
Based on the diet given for ten weeks, three groups of adult male Wistar rats were made (12 rats/group): (1) rats which fed on a chow diet and ordinary water, (2) rats which fed on KD and ordinary water and (3) rats which were given KD along with Zamzam. Fasting blood glucose (FBG), serum insulin, insulin resistance (HOMA-IR), LDL cholesterol, HDL cholesterol, superoxide dismutase and malondialdehyde were compared by one-way ANOVA followed by post-hoc Tukey’s HSD test among groups.
Findings
Rats which fed on KD and Zamzam water had significantly reduced FBG and LDL cholesterol compared to the rats which fed on a chow diet and ordinary water (p-values 0.001), and KD and ordinary water (p-value 0.004 and 0.006, respectively). Serum insulin, insulin resistance, HDL cholesterol, superoxide dismutase and malondialdehyde did not differ significantly.
Originality/value
Consumption of KD along with Zamzam for ten weeks significantly reduces FBG and LDL cholesterol. KD alone does not decrease these parameters in ten weeks duration.
