The purpose of this research is to identify and investigate some natural dyes with halochromic properties for potential use as food spoilage indicators to reduce waste and curve the negative effects of food borne diseases.

Exactly 10 potential dye-yielding plants were selected based on their colour (mostly purple, red, maroon and pink). Solvent extraction was used to extract the dyes and pH differential method was used to determine the concentrations of anthocyanin in the extracted dyes. Different concentrations of hydrochloric acid and sodium hydroxide (0.1 M, 1 M and 2 M) in drops and in excess as acidic and basic solution, respectively, were used to test the halochromicity of the extracted dyes. Methyl red (a synthetic dye) was used as a reference standard/control. The pH of the dyes was recorded before and after addition of both NaOH and HCl solutions.

Five out of the 10 dyes extracted (labelled as dye A–E for Ti plant (green Cordyline fruticosa), coleus (Coleus blumei), paper flower (Bougainvillea glabra), painted nettle (Palisandra coleus) and purple heart (Setcresea purpurea), respectively, were found to be halochromic (even at low doses) by changing its colour when exposed to both acidic and basic solutions. While other dyes labelled F–J for red acalypha (Acalypha wilkesiana), golden shower (Cassia fistula), golden dew drop (Duranta repens), wild sage (Lantana camara var Aculeata) and pink oleander (Apocynaceae Nerium oleander), respectively, were either completely insensitive to the solutions in drops, slightly sensitive at high doses or the colour change is insignificant. Although some dyes were found to be more sensitive than others but in most cases, the colour changes in halochromic dyes were more stable in acidic conditions than in basic making it more sensitive to the basic than the acidic solution with the exception of dye A and E (to some extent) which was sensitive to both acidic and basic solution. The anthocyanin contents of dye A–J were found to be between the range of 2.28–10.35 mg/l with dye E having the lowest and dye J with the highest anthocyanin concentration, respectively. The initial pH of all the dyes falls within the range of 4.8–7.3 with most found within the acidic range.

Halochromic dye research studies are still at the infancy stage in developing world despite the vast available and abundant potential natural halochromic dye-yielding plants. The study explored this area of research and gives an opportunity for the development of smart packaging for pH-sensitive foods using natural dyes as an alternative to conventional synthetic dyes to reduce cost and also curve the negative effect of synthetic dyes as well as food borne diseases.

It is globally recognized that food waste has significant economic, social and environmental impacts. This study endeavors to identify the individuals' underlying factors that affect food waste behavior in a social context in Egypt.

Due to the scarcity of research illustrating food waste in a social context, a qualitative research paradigm is employed. In-depth semi-structured interviews are conducted with 18 Egyptian households to report their experiences, thoughts and feelings while eating in a social context.

Based on thematic analysis using grounded theory procedures, eight main elements affecting creation and reduction of food waste in social contexts are identified. Additionally, the authors investigate the role of emotions in social dining contexts. A key finding is that food waste in social events is inevitable and is the acceptable norm in the Egyptian culture. Thus, the first step to reduce food waste is paying more attention to change culture. Persuading people with the negative consequences of food waste issue on behalf of their cultural values will be more challenging and may require more innovative approaches.

Although food waste issue is one of the contemporary issues in the world, very little is known about how social food consumption leads to food waste behavior. This study employs social influence theory and the collectivistic culture orientation to investigate the unanswered question of why food gets wasted in social meal context.

This paper aims to provide a living tribute to the leading autoethnographer, Alec Grant.

Alec provided Jerome with a list of names of people he might approach to write a tribute on his behalf.

The accounts describe the influence that Alec has had both as an educator and as a trusted colleague for the people approached.

While this is a living tribute, it is about one man and could, therefore, be described as a case study. Some people wonder what can be learned from a single case study. Read on and find out.

Alec has carved out a path for himself. In many senses, he chose “The Road Less Travelled”. He has never shied away from challenging “The System” and defending the rights of the marginalized and socially excluded. It is not a road for the faint-hearted.

For systems to change, radical thinkers need to show the way. “Change keeps us safe” (Stuart Bell).

Alec was a well-known and highly respected cognitive behavioural academic practitioner and the author of key textbooks in the field. He then decided to reinvent himself as an autoethnographer. This has brought him into contact with a much more diverse group of people. It has also brought him home to himself.

This study aims to propose that inclusive talent management (TM) philosophy and TM practices are related to individual outcomes, such as job satisfaction, turnover intentions and job performance.

Using the resource-based theory, the research explores the mediation relationship between inclusive TM philosophy and job satisfaction, turnover intentions and job performance via TM practices. The study uses structural equation modelling for analysing the data collected through a questionnaire-based survey among a sample of 373 employees and 65 supervisors.

The results show that inclusive TM philosophy is positively related to individuals’ job satisfaction, job performance and decreased turnover intentions, through TM practices.

The study’s limitation lies in its restriction to a narrow set of organizations operating in Romania, thus limiting the generalization of the findings. Consequently, future studies can extend the scope of the study to include a larger sample size consisting of more organizations operating across multiple sectors and countries. While it is appropriate to assess talent philosophies at the level of the individual employees, future studies may wish to tackle the constructs from the organizational (managerial) standpoint where the TM practices and programmes are designed. Furthermore, future researchers could draw comparisons with large enterprises to investigate the differences in the impact of implementing TM practices within these organizational types. Finally, future research could explore the outcomes of inclusive TM philosophy by using a qualitative design, which sheds more light on other factors that support or hinder the outcomes of embracing inclusive TM in organizations.

The study’s findings have practical implications for organizations that want to improve their employees’ outcomes and provide evidence on how organizations can achieve this through their TM practices. First, the paper establishes a relationship between inclusive TM philosophy and employees’ outcomes (turnover intention, job satisfaction and job performance) through the mediating impact of the organization’s TM practices in the context of organizations operating in Romania. The relevance of the context for TM studies has been highlighted in the literature, and thus, the findings make an important contribution to the TM literature, given the limited number of empirical studies on TM practices from emerging European countries (Skuza et al., 2013). Second, the model was tested empirically by collecting data from two sources – employees and supervisors from the surveyed organizations. The perception among employees that they are treated as a talent by the organization can have a positive impact on their satisfaction, and job performance, and decrease their turnover intentions. This suggests that organizations should invest in talent development programmes to help their employees develop into talented performers who help improve the organization’s performance. The findings are of particular importance to human resources practitioners, as it suggests that organizations should consider implementing TM practices systematically across the organization to ensure that all employees benefit from them. By doing this, organizations can improve individual outcomes, which can ultimately lead to improved organizational performance.

Organization that develop the talent of their workforce in its totality are likely to be more successful in the long term. Similarly, it can be inferred that organizations that enhance the talent of their workforce through practices such as staff rotation, talent identification are likely to derive greater benefit from the capabilities that their staff display.

The study sheds light on the impact of talent philosophies and TM practices on outcomes at the individual employees’ level, which is an understudied study area within the broader TM discipline.

This study aims to stimulate scholarly attention and practical application pertaining to individuals recognized as “Docs.” Through conducting a comprehensive analysis and acquiring a profound understanding of its many connotations, the objective is to shift attitudes and approaches concerning those who are seen to possess knowledge and value within society.

For this study, culturally relevant pedagogies were used as theoretical frameworks in addition to Sankofa and concept explication being used as methodologies.

The authors identified three themes: (1) honorary cultural practice-community nomination of “professahs” and “docs,” (2) (Black) robinhoods – cultural signifiers of distinction and relatability and (3) docs as catalysts – elevating community via consciousness, trust and mentorship as significant understandings of this distinction.

The study emphasizes the importance of “Docs” in both academic and social contexts. The role of “Docs” serves to alleviate potential conflicts of being a Black intellectual. This study further reveals the ways in which Docs align with, promote or possibly undermine established frameworks of thought. Finally, this study provides institutions with opportunities to consider strategies for the utilization, recognition and integration of individuals who are frequently overlooked or undervalued.

This study aims to examine the subjective well-being of self-employed persons relative to wage employees in Ghana. Two measures of subjective well-being, comprising life satisfaction and happiness, are considered.

The current study focuses on Ghanaian working adults, uses pooled cross-sectional datasets from the 2005 to 2014 World Values Survey (WVS), applies survey weights, estimates ordered probit models and computes marginal effects.

The results show that being self-employed is associated with a lower probability of being satisfied with life than being wage employed. The result for happiness is negative but not statistically significant. The perceived low level of life satisfaction among the self-employed in Ghana could explain the rationale behind the desire of some Ghanaians to seek wage employment rather than pursuing self-employment. The results also could partly explain the non-survival of some entrepreneurial firms in Ghana over time.

Data relating to factors such as business size, location (urban or rural), degree of internationalization (domestic or foreign), number of years of being in self-employment, the number of employees, financial knowledge and behavior and personality traits are unavailable in the WVS for analyses. The present study also uses a pooled cross-sectional dataset for the analyses; thus, causal inferences are not possible.

The study provides empirical evidence on the relationship between self-employment and subjective well-being in the context of Ghana. The study provides insights into how self-employed Ghanaians perceive well-being relative to wage employees.

While prior research has established that traumatic brain injury (TBI) is a risk factor for violent offending, there is little understanding of mechanisms that may underpin this relationship. This is problematic, as a better understanding of these mechanisms could facilitate more effective targeting of treatment. This study aims to address these gaps in the extant literature by examining TBI as a predictor of violent offending and test for mediation effects through cognitive constructs of dual systems imbalance and hostility among a sample of justice-involved youth (JIY).

The Pathways to Desistance data were analyzed. The first three waves of this data set comprising the responses of 1,354 JIY were analyzed. Generalized structural equation modeling was used to test for direct and indirect effects of interest. A bootstrap resampling process was used to compute unbiased standard errors for determining the statistical significance of mediation effects.

Lifetime experience of TBI was associated with increased violent offending frequency at follow-up. Hostility significantly mediated this relationship, but dual systems imbalance did not. This indicated that programming focused on reducing hostility among JIY who have experienced TBI could aid in reducing violent recidivism rates.

To the best of the author’s knowledge, this study was the first to identify significant mediation of the relationship between TBI and violent offending through hostility.

This paper aims to examine the conditions under which small and medium enterprises (SMEs) invest in security services when they migrate their e-commerce applications to the cloud environment. Using a risk management perspective, the paper assesses the impact of security service pricing, security incident prevalence and virulence to estimate SME security spending at the market level and draw out implications for SMEs and security service providers.

Security risks are inherently characterized by uncertainty. This study uses a Monte Carlo approach to understand the role of uncertainty in the decision to adopt security services. A model relating key security constructs is assembled based on key constructs from the domain. By manipulating security service costs and security incident types, the model estimates the market-level adoption of services, security incidents and damages incurred, along with measures of their relative dispersion.

Three key findings emerge from this study. First, adoption of services and protection is higher when tiered security services are provided, indicating that SMEs prefer to choose their security services rather than accept uniformly priced products. Second, SMEs are considered price-sensitive, resulting in a maximum level of spending in the market. Third, results indicate that security incidents and damages can be much higher than the mean in some cases, and this should serve as a cautionary note to SMEs.

Security spending has been modeled at the firm level. Adopting a market-level perspective represents a novel contribution. Additionally, the Monte Carlo approach provides managers with tangible measures of uncertainty, affording additional information and insight when making security service adoption decisions.

This study responded to the call to empirically reconcile conflicting findings in unethical pro-organizational behavior (UPB) literature. It did so by examining the influence of organizational culture on the relationship between affective organizational commitment and UPB.

Using a sample of 710 U.S. service sector employees based on a three-wave data collection design, structural invariance assessment was utilized to evaluate the relationship between affective organizational commitment and UPB across organizational cultures with opposing effectiveness criteria (i.e. focused on stability vs flexibility).

The result indicated a statistically significant positive direct effect between affective organizational commitment and UPB for the stability-focused cultures, while finding a statistically insignificant effect for the flexibility-focused cultures. These results support organizational culture research, which shows that organizational cultures with opposing effectiveness criteria (i.e. stability vs flexibility) can either encourage or discourage ethical behavior.

While leaders and managers encourage employee commitment to the organization, it is important to understand that increased organizational commitment is not limited to positive outcomes. Cultivating elements of flexibility-oriented cultures, like promoting teamwork (as in clan cultures) or fostering innovation and adaptability (as in adhocracy cultures), can be a strategic approach to minimize the chances of UPB among committed employees.

By integrating insights from social exchange theory, Trevino’s interactionist model and the competing values framework, we have contributed to a nuanced understanding of how different organizational cultures can suppress or stimulate UPB.

This study investigates the validity of Ferreira et al.’s (2020) Organizational Bullshit Perception Scale by examining its distinctiveness from similar constructs (perceptions of organizational politics, organizational cynicism, procedural justice) and its predictive validity through its relations with important organizational attitudes (organizational identification) and behaviors (counterproductive work behavior and organizational citizenship behavior). This study also examines the moderating effects of honesty–humility on the relations between organizational bullshit perception and the outcomes of counterproductive work behavior, organizational citizenship behavior and organizational identification. Finally, this study examines the incremental validity of organizational bullshit perception in predicting counterproductive work behavior, organizational citizenship behavior and organizational identification above and beyond similar constructs in an exploratory fashion.

Survey data were collected from a sample of working adults online via Amazon’s Mechanical Turk platform across two waves (final N = 323 for wave 1 and 174 for wave 2), one month apart.

The results indicate that organizational bullshit perception, as measured by Ferreira et al.’s (2020) scale, represents a distinct construct that has statistically significant relations with counterproductive work behavior, organizational citizenship behavior and organizational identification, even after controlling for procedural justice, organizational cynicism and perceptions of organizational politics. The results, however, showed no support for honesty–humility as a moderator.

These findings suggest that organizations can benefit from assessing and working to alleviate their employees’ perceptions of organizational bullshit. This construct predicts behaviors and attitudes important for organizational functioning.

This study adds to Ferreira et al.’s (2020) original work by demonstrating organizational bullshit perception’s distinctiveness from existing constructs in the literature and its implications for organizations and their employees.
