Abstract
This study examines whether the Hong Kong stock market overreacts. By using monthly return data of all the common stocks listed on the Hong Kong Stock Exchange from January 1980 to December 1995, it examines the profitability of a contrarian strategy of buying prior losers and selling prior winners. The evidence shows that prior losers outperform prior winners by up to 68.59% in the subsequent five‐year test period. This finding can be interpreted as investors' tendency to react over‐optimistically to positive information and over‐pessimistically to negative information, thus causing stock prices to take temporary swing away from their intrinsic values and then reverse back subsequently. Our result is consistent with that documented by Debondt and Thaler (1985) for the U.S. market. This study also investigates whether seasonality accounts for the abnormal return but finds that the overreaction effect is not caused by the well‐known January effect. Further tests are conducted to investigate whether changes in betas of the winners and losers account for the abnormal return. The evidence shows that such changes are also minor, which cannot explain the price reversal phenomenon.

Abstract
Purpose
The purpose of this paper is to understand various organizational and operational impediments to successful built heritage management at a regional level from the perspective of stakeholder theory.
Design/methodology/approach
An exploratory study was conducted in Jammu city of India wherein total of 16 interviews using a semi-structured questionnaire were done with officials (N = 6), organization members (N = 7), local organization heads (N = 3) and 30 local residents. Thematic analysis and stakeholder analysis were used to identify themes and examine the relationships between stakeholders.
Findings
Six themes were derived from thematic analysis. The results from stakeholder attribute analysis and studying stakeholder interactions show that lack of trust, skewed power relation and lack of communication among stakeholders are some of the factors that hinder successful heritage management at the Mubarak Mandi heritage complex. The study emphasizes the dimension of “authenticity” be added to existing discourse of heritage management in India ensuring commoditization does not override authenticity and integrity of heritage site.
Originality/value
The results of this study are useful in understanding challenges of heritage management in India at regional level. Using stakeholder analysis the study adds a managerial perspective to the existing heritage management discourse in India by providing empirical insights into developing stakeholder collaboration.

Abstract
Purpose
Market efficiency leads to transparent and fair price discovery of commodity markets, thus enhancing the value chain for competitive benefit. The purpose of this paper is to investigate the market efficiency of Indian agricultural commodities at spot, futures and mandi markets apart from exploring price risk management in these markets.
Design/methodology/approach
This study uses Johansen co-integration, vector error correction model and granger causality for analyzing market efficiency of the nine most liquid agricultural commodities across three markets, namely, spot, futures and mandi. All these nine commodities are traded on National Commodity and Derivatives Exchange.
Findings
The statistical results indicate price discovery exists in the mandi market and spot market leading to futures prices. Mandi price returns are seen to negatively influence futures returns in the case of cotton seed, guar seed and spot returns in the case of jeera, coriander and chana. For castor seed, the three markets are seen to have no long run relationship. The results of Granger causality reveal short run relationship between all the three markets in the case of soybean seed and coriander. In these commodities, prices in all three markets are capable of predicting the prices in the other markets. For the case of cottonseed, Rape Mustard seed, jeera, guar seed, the results indicate unidirectional causality between the mandi markets and the other two markets.
Research limitations/implications
These results shall facilitate policymakers to explore intervention through integrated agri-platform (IAP) in price discovery and market efficiency.
Practical implications
The results of this study are useful in understanding the price discovery of mandi markets and its role in the spot and futures market. Agricultural commodities price discovery depends upon the integration of all these three markets. Introduction of IAP as described in the paper shall facilitate price risk management apart from improving the efficiency of price discovery.
Originality/value
To the best of the knowledge, this is the first study considering mandi, spot and futures prices in the price discovery process in India. In addition, this study found the role of mandi markets in serving the economic function of price discovery and price risk management. Hence, suggests for policy intervention for Indian agricultural commodities to manage price risk.

Abstract
Purpose
The presence of broken clouds leads to frequent fluctuations in direct normal incident solar irradiation as well as diffuse radiation from the sky. This brings a lot of challenge for grid integration of solar power plants. The paper aims to discuss this issue.
Design/methodology/approach
A new model is presented to nowcast solar radiation by utilizing hourly global horizontal irradiance (GHI) over a large spatial grid. The spatial distribution of the GHI provides information on the presence of a cloud shadow above a given site. This information is extracted with the help of various data processing techniques. The spatial–temporal data analysis is employed to track the extracted cloud shadow image based on a dynamic model. A Kalman filter is applied for the assimilation of data in the tracking of the extracted shadow over a geographical location.
Findings
The proposed model can provide very good forecasting of solar radiation for various time horizons. However, the variation of shadow features between time steps must be included in the dynamic model to forecast accurate GHI values.
Research limitations/implications
In this paper database used is on hourly basis; it can be further improved for the inter-hour level of ground data for more accuracy.
Practical implications
The outcome of this paper would be useful in the field of solar energy application and for weather monitoring purposes.
Originality/value
The forecasted position of the shadow is utilized to prepare and forecast a GHI map for one hour time horizon. Results show that the model can be utilized to forecast solar radiation with accuracy consistent with the contemporary models.

Abstract
Purpose
Community gardens are increasingly used as interventions during the resettlement of refugees and other migrants. Little is known about how garden programs might support their mental health and wellbeing. Given the links between climate change and forced migration, community gardens are especially relevant, as they can also support climate change mitigation. This study aims to document psychosocial outcomes of gardening programs for refugees and migrants, and mechanisms leading to these outcomes.
Design/methodology/approach
The authors searched major databases and the grey literature up to 2021, resulting in the inclusion of 17 peer-reviewed and 4 grey literature articles in a thematic, qualitative analysis.
Findings
Four consistent themes arose from the analysis: community gardening programs promoted continuity and adaptation (81% of articles), social connectedness (81%), overall wellbeing (95%) and a sense of meaning and self-worth (67%). The results suggest that community gardens can strengthen psychosocial pillars that are key to the recovery and resettlement of refugees and migrants. The land-based and social nature of community gardening may enable connections to the land and others, nurture a sense of belonging in the host country and provide a link to the past for those from agricultural backgrounds.
Research limitations/implications
Further participatory action research is needed to develop guidelines for the successful implementation of community gardens by resettlement organisations.
Originality/value
This review indicates that community gardens can be effective psychosocial interventions as part of a network of services supporting the resettlement of refugees and migrants.

Abstract
Purpose
Females with autism spectrum disorder (ASD) may display superficial social skills which may mask their ASD symptomology impacting on the identification of the disorder – known as the “camouflage” hypothesis. Compared to males with ASD, it is increasingly recognised that females with ASD have a stronger ability to imitate behaviour which is socially acceptable, particularly those females who have higher cognitive abilities (i.e. intelligence considered to be within the normal range) (Ehlers and Gillberg, 1993). The paper aims to discuss this issue.
Design/methodology/approach
This paper will explore the literature on camouflaging or masking behaviour in females with ASD. A systematic PRISMA review was conducted.
Findings
The capacity to “camouflage” social difficulties in social situations is considered to be one of the main features of the female phenotype of ASD (e.g. Kenyon, 2014). Social imitation or camouflaging enables some level of success and coping, which results in some females never receiving a diagnosis of ASD. They typically may not exhibit any observable functional impairments. However, under the surface of the camouflage, females may experience high levels of subjective stress, anxiety and exhaustion and a need to re-charge or recuperate by withdrawing from any social interaction.
Research limitations/implications
There is relatively little understanding and knowledge of the female phenotype of ASD. This lack of understanding and knowledge impacts significantly on the ability to identify females with ASD (Lai et al., 2015; Bargiela et al., 2016), which can have a number of negative consequence (Adamou et al., 2018; National Collaborating Centre for Mental Health (UK), 2012).
Practical implications
There is a need for the development of a camouflaging measure.
Originality/value
There is a real need for further research exploring the positive and negative impact of the phenomenon of “camouflaging”, or “pretending to be normal” in females with ASD.

Abstract
Purpose
Celiac disease is an auto-immune disorder that requires strict lifelong adherence to a gluten-free diet. I explore how a celiac diagnosis affects gendered feeding work within families.
Methodology/approach
This chapter is based on a grounded theory analysis of field research with five celiac support groups and 80 in-depth interviews. I interviewed 15 adult men and 56 adult women with celiac, plus nine additional family members.
Findings
Gendered care work norms place the onus of responsibility for gluten-free feeding work on women, multiplying time spent planning, shopping, and preparing meals. Women employ distinct gendered strategies to accommodate the gluten-free diet. Following a strategy of integration, women tailor family meals to meet other diagnosed family members’ dietary needs and the entire family’s taste preferences. However, when women themselves have celiac, they follow a pattern of deferential subordination, not allowing their own dietary needs to alter family meals. Thus, women continue to prepare family meals as a form of care for others, even when their medical needs justify putting themselves first.
Originality/value
Social support is a key determinant of compliance with necessary lifestyle and dietary changes in chronic illness. However, little research explores the gendered dynamics within families accounting for the link between social support and dietary compliance. I show how gendered care work norms benefit husbands and children with celiac, while simultaneously disadvantaging women with celiac.

Abstract
Purpose
The rise in the incarceration of Aboriginal and Torres Strait Islander mothers is a major public health issue with multiple sequelae for Aboriginal children and the cohesiveness of Aboriginal communities. The purpose of this paper is to review the available literature relating to Australian Aboriginal women prisoners’ experiences of being a mother.
Design/methodology/approach
The literature search covered bibliographic databases from criminology, sociology and anthropology, and Australian history. The authors review the literature on: traditional and contemporary Aboriginal mothering roles, values and practices; historical accounts of the impacts of white settlement of Australia and subsequent Aboriginal affairs policies and practices; and women’s and mothers’ experiences of imprisonment.
Findings
The review found that the cultural experiences of mothering are unique to Aboriginal mothers and contrasted to non-Aboriginal concepts. The ways that incarceration of Aboriginal mothers disrupts child rearing practices within the cultural kinship system are identified.
Practical implications
Aboriginal women have unique circumstances relevant to the concept of motherhood that need to be understood to develop culturally relevant policy and programs. The burden of disease and cycle of incarceration within Aboriginal families can be addressed by improving health outcomes for incarcerated Aboriginal mothers and female carers.
Originality/value
To the authors’ knowledge, this is the first literature review on Australian Aboriginal women prisoners’ experiences of being a mother.

Abstract
Purpose
The purpose of this study is to qualitatively explore and describe the social environment of CrossFit®.
Design/methodology/approach
A total of 6 focus groups (n = 48) and 16 interviews were held with CrossFit® participants, coaches and owners. Each focus group or interview was facilitated by trained members of the research team. After data collection was complete, four trained researchers analyzed transcriptions using an open coding method to derive themes from responses, followed by inter-rater reliability checks to ensure consistency in data analysis.
Findings
Five themes emerged including: support (the social capital community members received from others through CrossFit®, including encouragement, coaching and accountability); culture (describes how CrossFit® as a community embraces a variety of skill levels and members experience a sense of camaraderie, acceptance and shared goals); social aspect (ways CrossFit® incorporates and extends community through a welcoming environment and fostering relationships building); competition (competing with others and oneself at CrossFit® is key to motivation and success at the gym); and barriers to community (ways CrossFit® can at times be intimidating).
Practical implications
Although exploratory, this study suggests the importance of CrossFit®’s social environment for a participant’s experience. Future research could determine how relationships within CrossFit® relate to health outcomes.
Originality/value
This research is original and important to the field of mental health as it explores how CrossFit® can be leveraged as a strategy to promote social inclusion. CrossFit® provides an environment that promotes healthy habits such as community involvement and exercise.
