This study aims to describe the design and synthesis of two novel azo and imine chromophores-based dyes derived from two different aldehydes with intramolecular colour matching that are pH sensitive.

The visible absorption wavelength (λ_max) was extended when azo chromophore was included in imine-based systems. The dyed patterns created sophisticated colour-changing paper packaging sensors with pH-sensitive chromophores using alum as a mediator or mordant. Due to the tight adhesive bonding, the dyes on paper’s cellulose fibres could not be removed by ordinary water even at extremely high or low pH, which was confirmed by scanning electron microscopy analysis. The dyed patterns demonstrated an evident, sensitive and fast colour-changing mechanism with varying pH, from pale yellow to red for Dye-I and from pale yellow to brown-violet for Dye-II.

The λ_max for colour changing was recorded from 400 to 490 nm for Dye-I, whereas from 400 to 520 for Dye-II. The freshness judgement of food was checked using actual experiments with cooked crab spoilage, where the cooked crab was incubated at 37 ^oC for 6 h to see the noticeable colour change from yellow to brown-violet with Dye-II. The colour-changing mechanism was studied with Fourier transform infrared (FTIR) spectra at different pH, and thin layer chromatography, nuclear magnetic resonance and FTIR spectroscopy studied the desired structure formation of the dyes. Potential uses for smart packaging sensors include quickly detecting food freshness during transportation or right before consumption.

1. Two novel azo-imine dyes have been synthesized with a pH-responsive effect. 2. The pH-responsive mechanism was studied. 3. The study was supported by computational chemistry using density functional theory. 4. The obtained dyes were used to make pH-responsive sensors for seafood packaging to judge the freshness.

In this paper, we focus on how and when organizations adopt different types of ambidexterity to facilitate projects that operate with fundamentally different time scales compared with the dominant functions of the organization.

Using a comparative case study design, four case studies were conducted of long-term projects in two similar manufacturing plants within the same organization.

We found organizations first use structural and sequential ambidexterity in change efforts, during which new process knowledge is developed. When structural and sequential ambidexterity are not viable, change agents use this developed knowledge to support contextual ambidexterity. This contextual ambidexterity allows change agents to move between distinct time conceptions of event time and clock time.

One of the limitations of this study was that it only focused on two plants within one organization in order to control for variation. Future studies should look at a wider range of companies, technologies and industries.

While structurally and temporally decoupling change efforts help with differentiation of new technological change, there are limitations with these efforts. It is important to build an organization’s contextual ambidexterity as well as organizational supports to facilitate switching between clock time and event time.

This paper helps explain how and when organizations use different types of ambidexterity in resolving temporal conflicts when implementing longer-term technological change in fast-paced manufacturing settings.

This study aims to investigate the evolving travel intentions of tourists in the aftermath of the relaxation of international mobility restrictions in 2022. It aims to understand how the concept of “revenge travel” – travelling with the intent to make up for lost time during crisis periods – impacts tourists' travel intentions in the post-crisis era.

Employing a quantitative approach, the study uses Structural Equation Modelling (SEM). Data were collected through a survey of 320 respondents in 2022. This methodology enables a comprehensive understanding of travel intentions, including motivations, perceptions of destination safety and the influence of revenge travel.

The findings reveal that revenge travel is a significant predictor of travel intentions post-crisis. The results indicate that tourists are less concerned with health and safety and are more driven by the desire to compensate for lost travel opportunities. This shift suggests that travel intentions in the post-crisis era are not predominantly fear-induced. The study also offers insights into how these intentions can inform the recovery and sustainable planning of the tourism industry.

This paper recognises the impact of revenge travel on travel intentions following the lifting of crisis-related mobility restrictions. It provides novel insights into tourists' post-crisis travel behaviour, extending the understanding of travel motivations in extraordinary circumstances. The findings are valuable for tourism practitioners and researchers, offering guidance for future tourism development and marketing strategies within a post-crisis context.

Academic libraries are having to reconsider personnel, collections, space, and budget. This paper provides examples of how rightsizing opportunities in those areas can be approached in a positive way.

Librarians at a small, rural, public university library approached rightsizing as an opportunity to shape the library in positive ways. This paper provides a reflection on those efforts in personnel, collections, space, and budget that have taken place over the past decade at this university, and highlights how the library’s role as the driver of these changes helped foster a positive culture.

This paper explains the ways the library is viewed both internally and externally as a more student-focused service and location. Examples in this paper may provide ideas for other libraries to utilize in their rightsizing efforts.

Historically, this library encountered forced cuts due to lower than anticipated enrollments and reduced funding from the state. This contributed to low morale and understandably defensive attitudes; however, these did not serve the library well. Post 2013, the library transitioned to a self-initiated approach to making changes. Some of these changes came about due to stagnation in budgets while others can be attributed to changes in staff due to retirements and new hires. Through this shift to proactive rightsizing, our library team has recognized we are adaptable and nimble. This has benefitted morale and helped the library grow a positive reputation on campus.

The warehouse receipt system (WRS) is critical for farmers because it addresses agricultural market inefficiencies, provides credit access, reduces postharvest losses and increases access to profitable markets. However, its use and implementation across the commodity value chain remain relatively limited in Sub-Saharan Africa, particularly among cash crop producers. This study examines cashew farmers' perceptions of WRS implementation and determinants of farmer participation.

A total of 153 cashew farmers from the Bono region of Ghana were sampled using a multistage sampling approach. Perception index analysis and Cragg's double hurdle model were used for the analysis.

The results revealed that farmers strongly perceived that WRS augmented credit and market access. In addition, farm size, household size, annual income, perception of collateral and higher selling price determined farmers' willingness to participate in WRS.

Despite the existence of other cashew farmers in Ghana, the study was limited to cashew farmers in Bono Region.

Despite the plethora of benefits of WRS, it is surprising that its implementation in the cashew subsector is geographically limited to East Africa. Thus, this study is the first to provide empirical evidence on the perception of WRS implementation and further examine farmers' willingness to participate in WRS in Ghana.

This study examines the impact of ethics education interventions (EEI) on attaining ethical education goals in higher institutions.

The study utilizes a survey method, with questionnaires distributed to accounting instructors from universities and professional accountants in Ghana. The empirical analysis is based on 417 valid responses, and the hypothesized relationships are tested using ordinary least square (OLS) regression.

The results indicate that ethics-related courses (ERC), methods of teaching ethics (MTE) and methods of ethics interventions (MEI) have a positive and significant impact on achieving the objective set for EEI in accounting programs.

This study provides valuable insights for accounting educators and professional body managers in developing accounting ethics curricula in universities and professional accounting institutions.

This study involves accounting educators and professionals and applies ethical theories of egoism, deontology and utilitarianism to demonstrate the role of ethical interventions in accounting programs in achieving set objectives from a developing country context.

The organizational environment can influence how employees experience meaningfulness. This study examines the mediating role of meaningful work between organizational ethical climates and the affective well-being of employees. We also test for the moderating role of self-regulatory traits in this relationship.

Partial least squares – structural equation modelling (PLS-SEM) was employed to test the hypothesized model using responses from 430 working professionals. Recommended robustness checks were conducted before model assessment and hypotheses testing.

The findings suggest that a caring ethical climate is positively related to affective well-being. Meaningful work dimensions, i.e. unity with others, inspiration and balancing tensions partially mediate the relationship between the caring climate and affective well-being. Integrity with self and balancing tensions fully mediate the negative effect of an instrumental climate on affective well-being. Positive mediation of unity with others and negative mediation of reality were observed between a law and code climate and affective well-being. Moderating effects of self- and other-orientation and self-monitoring were also observed.

The study presents significant insights, however, a few limitations must be discussed. The study has relied on cross-sectional data which may be addressed in future studies.

In times when organizations are spending in large amounts in ensuring meaningful work and employee well-being, this study suggests internal mechanisms that can bring positive impact in employees' work life. Leaders should assess how employees perceive the ethical climate of the organization in order to provide better meaningful work opportunities to the workforce.

Having meaningful work and experiencing affective well-being are significant for a collective betterment of society. Meaningful work encourages individuals in identifying how their work if affecting the society. A affectively happy workforce is essential in building a mentally healthy society.

This study contributes to the investigation of organizational factors that help employees find meaning in their work. Based on ethical climate theory, this study highlights how organizations can redesign and modify their ethical climates to provide opportunities for employees to experience meaningful work and improve their affective well-being.

The study aims to explore how young adults perceive cooking contents on social media and their interaction with it.

Qualitative study using semi structured interviews with Brazilian young adults who cook (19–24 years old, n = 31) was the method employed. Interview audio recordings were transcribed and submitted to inductive and reflexive thematic analysis.

Data analysis generated six different themes. Young adults valued the profiles’ aesthetics and quality in terms of straightforwardness, trustworthiness, novelty and authenticity of information; they also identified with the profiles’ authors. When pressed for time, aesthetics was less valued than straightforwardness. Participants felt overwhelmed by the excessive information on social media and developed coping strategies to deal with this issue.

The lack of cooking and food skills is a recognized barrier for healthy eating in the young adult population. Social media can play a prominent role in delivering cooking-related information to the younger generation, but research on people’s perceptions of the cooking content available online is scarce and does not focus on how actual engagement with the available content happens. This qualitative exploration revealed which features young adults prefer when using social media to access cooking content, which can inform future interventions to promote cooking and improve health.

This study uses computer-aided design to improve the ecological and environmental sustainability of early-stage landscape designs. Urban expansion on open land and natural habitats has led to a decline in biodiversity and increased climate change impacts, affecting urban inhabitants' quality of life and well-being. While sustainability indicators have been employed to assess the performance of buildings and neighbourhoods, landscape designs' ecological and environmental sustainability has received comparatively less attention, particularly in early-design stages where applying sustainability approaches is impactful.

The authors propose a computation framework for evaluating key landscape sustainability indicators and providing real-time feedback to designers. The method integrates spatial indicators with widely recognized sustainability rating system credits. A specialized tool was developed for measuring biomass optimization, precipitation management and urban heat mitigation, and a proof-of-concept experiment tested the tool's effectiveness on three Mediterranean neighbourhood-level designs.

The results show a clear connection between the applied design strategy to the indicator behaviour. This connection enhances the ability to establish sustainability benchmarks for different types of landscape developments using parametric design.

The study allows non-expert designers to measure and embed landscape sustainability early in the design stages, thus lowering the entry level for incorporating biodiversity enhancement and climate mitigation approaches.

This study expands the parametric vocabulary for measuring landscape sustainability by introducing spatial ecosystem services and architectural sustainability indicators on a unified platform, enabling the integration of critical climate and biodiversity-loss solutions earlier in the development process.

The e-services market is expected to reach nearly $500bn globally by 2028. As this marketplace grows, customer-to-customer interactions (CCIs) occurring through virtual channels will likely increase. Consequently, the purpose of this research is to examine how the context in which CCI’s occur (i.e. virtual vs in-person) and the frequency of their occurrence affects customer identification, leading to increased customer engagement and more favorable purchase behaviors.

Two studies were conducted to test the proposed models and hypotheses. The sample for Study 1 is comprised of college students taking in-person or online classes (n = 290). In Study 2, members of an online brand community (n = 125) were surveyed. Hypotheses were tested using structural equation modeling (SEM).

Overall, results support a mediation effect such that CCI context (virtual vs in-person) affects customer engagement and purchase behaviors via customer identification. Specifically, Study 1 finds that customer engagement behaviors (CEBs) are greater for in-person CCIs due to the frequency of interactions and heightened identification between customers. Study 2 further examines the CCI frequency-identification link and finds that customer-firm identification is the only form of identification that affects CEBs and purchase behaviors.

Limited customer engagement research has examined the effects of CCIs on CEBs, and research has rarely compared in-person to virtual CCI contexts. This paper addresses these shortcomings by testing the effects of in-person and virtual CCIs on CCI frequency, identification and CEBs. This research fills another important gap in the literature by considering the unique effects of specific dimensions of customer identification on CEBs and purchase behaviors.
