Due to their outstanding thermal stability, polyimides are now being carefully considered for use as matrix resins, adhesives, films and coatings. If successful, this unique class of polymers could greatly extend the present upper limit of 177°–205°C achievable in aerospace work with even higher temperatures and longer service life.

Contemporary literature reveals that, to date, the poultry livestock sector has not received sufficient research attention. This particular industry suffers from unstructured supply chain practices, lack of awareness of the implications of the sustainability concept and failure to recycle poultry wastes. The current research thus attempts to develop an integrated supply chain model in the context of poultry industry in Bangladesh. The study considers both sustainability and supply chain issues in order to incorporate them in the poultry supply chain. By placing the forward and reverse supply chains in a single framework, existing problems can be resolved to gain economic, social and environmental benefits, which will be more sustainable than the present practices.

The theoretical underpinning of this research is ‘sustainability’ and the ‘supply chain processes’ in order to examine possible improvements in the poultry production process along with waste management. The research adopts the positivist paradigm and ‘design science’ methods with the support of system dynamics (SD) and the case study methods. Initially, a mental model is developed followed by the causal loop diagram based on in-depth interviews, focus group discussions and observation techniques. The causal model helps to understand the linkages between the associated variables for each issue. Finally, the causal loop diagram is transformed into a stock and flow (quantitative) model, which is a prerequisite for SD-based simulation modelling. A decision support system (DSS) is then developed to analyse the complex decision-making process along the supply chains.

The findings reveal that integration of the supply chain can bring economic, social and environmental sustainability along with a structured production process. It is also observed that the poultry industry can apply the model outcomes in the real-life practices with minor adjustments. This present research has both theoretical and practical implications. The proposed model’s unique characteristics in mitigating the existing problems are supported by the sustainability and supply chain theories. As for practical implications, the poultry industry in Bangladesh can follow the proposed supply chain structure (as par the research model) and test various policies via simulation prior to its application. Positive outcomes of the simulation study may provide enough confidence to implement the desired changes within the industry and their supply chain networks.

Incidents requiring command and control require all personnel from firefighters (FFs) to the incident commander (IC) to make continuous decisions often with limited information and under acute time-pressure. Therefore, the purpose of this paper is to explore the stress reactivity of specific roles during the command and control of an immersive, computer-based incident.

Experienced firefighting personnel undergoing incident command training participated in this study. Participants completed measures of state anxiety and stress immediately before and after taking part in a computer-based simulation of a large-scale incident run in real time. During the simulation personnel assumed one of four roles: IC, sector commander, entry control officer (ECO), and command support officer. Following the simulation personnel then completed measures of perceived workload.

No significant changes in state anxiety were observed, but levels of stress and perceived workload were related to task roles. Specifically, ICs reported the greatest levels of mental and temporal demands and stress when compared with ECOs.

Limitations include the lack of environmental factors (such as rain, darkness, and noise), a relatively small sample size, and the use of self-reported questionnaires.

The application of immersive training environments as a method of developing FFs experience of incident command roles and skills pertinent to high-acuity, low-frequency events.

The paper represents one of the first attempts to identify the self-reported anxiety, stress, and perceived workload of specific role demands during the command and control of simulated incidents.

An extensive survey of over 300 reports worldwide shows that the state‐of‐the‐art in tactile sensing — defined as continuously variable touch sensing over an area where there is special resolution — is primitive. Only now is a new level of sophistication beginning to appear. However, for industrial systems the simplest may prove to be the most reliable.

The inclusion of LGBTQ + persons (lesbian, gay, bisexual, transgender, queer and having other sexual orientations and gender identities) is a crucial step in improving gender diversity in the workplace; however, till date, it remains a significant challenge for human resource management professionals. The current study critically examines this issue of an inclusive workplace for LGBTQ + people through a systematic review of the existing research that has empirically studied their experiences at the workplace. It also examines the resistance and challenges organizations face in LGBTQ + diversity training and provides future research avenues.

For systematically reviewing the literature, Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) model has been used. A total of 101 empirical studies have been reviewed.

The result shows that LGBTQ + people encounter multiple negative workplace experiences, including proximal (hiring discrimination and housing discrimination) and distal workplace discrimination (unsafe work climate, microaggressions and harassment). These aversive experiences lead to work stress while also mandating that people manage their sexual identity and style of dressing. This stress, in turn, impacts their work–family outcomes, job satisfaction and decision-making with regard to their careers.

The paper provides a holistic understanding of the aversive workplace experiences encountered by sexual minorities.

For Colombia, cocaine is a product that is sold for profit in the United States. Mainstream political economy, let alone the other social sciences, has little to say about the process of extraction of surplus value in the production and distribution of cocaine, in other words, how cocaine is exploited for profit. The paper argues that the conventional framework, which locates profits generated from the cocaine trade in an economic model of crime shields a much deeper reality than simply ‘money laundering’ as a ‘legal problem.’ The central argument is that the cocaine trade in general, and the cocaine economy in particular, are a vital aspect of U.S. imperialism in the Colombian economic system. The paper tackles a critical problem: the place of cocaine in the re-colonization of Colombia – defined as ‘narcocolonialism’ – and the implications of the cocaine trade generally for U.S. imperialism in this context. The paper evaluates selected literature on the Colombian cocaine trade and offers an alternative framework underpinned by a political economy analysis drawn from Marx and Lenin showing that cocaine functions as an ‘imperial commodity’ – a commodity for which there exists a lucrative market and profit-making opportunity. It is also a means of capital accumulation by what could be termed, Colombia's comprador ‘narcobourgeoisie;’ dependent on U.S. imperialism. It is hoped that by analyzing cocaine with a Marxist interpretation and political economy approach, then future developments in understanding drugs in Colombia's complex political economy may be anticipated.

This paper aims to demonstrate the role that the Google general search engine plays in the information‐seeking behaviour of scientists, particularly physicists and astronomers.

The paper is based on a mixed‐methods study including 56 semi‐structured interviews, a questionnaire survey of 114 respondents (47 per cent response rate) and the use of information‐event cards to collect critical incident data. The study was conducted at the Department of Physics and Astronomy at University College, London.

The results show that Google is the tool most used for problem‐specific information seeking. The results also show the growing reliance of scientists on general search engines, particularly Google, for finding scholarly articles. Initially, finding scholarly articles was a by‐product of general searching for information rather than focused searches for papers. However, a growing number of articles read by scientists are identified through the Google general search engine and, as scientists are becoming more aware of the quantity of scholarly papers searchable by Google, they are increasingly relying on Google for finding scholarly literature.

As the only fields covered in the study were physics and astronomy, and the research participants were sourced from just one department of one institution, caution should be taken in generalising the findings.

The data are based on a mixed‐methods in‐depth study of scientists' information‐seeking behaviour which sheds some light on a question raised in past studies relating to the reason for the high number of articles identified through Google.

This paper aims to take note of the need to better understand cost consciousness from a management accounting perspective and serves as an exploratory study striving to analyze how the notion has been addressed by management accounting scholars.

This paper presents the findings of a thorough literature review identifying the drivers, interpretations, definitions and results which management accounting scholars have associated with cost consciousness.

This paper has synthesized the definitions and interpretations by considering their conceptual broadness and the subjects that cost consciousness characterizes. In addition, various potential drivers of cost consciousness have been identified where management control systems play a major role. Also, this paper summarizes both the positive and negative outcomes which scholars seem to expect from an increase of cost consciousness.

Given that no prior work has focused on the conceptual development of cost consciousness, it was necessary to infer most of the interpretations, drivers and results which management accounting scholars have associated to the cost consciousness notion.

Cost consciousness is a concept that appears in hundreds of peer-reviewed articles on management accounting. However, only a handful of management accounting scholars have defined or evaluated this concept to a certain degree. As a result, what management accountants believe cost consciousness to be, how it is driven and what result may be expected from it, is nowhere to be found in any synthesized manner. The findings of this paper develop the concept of cost consciousness by illuminating the common use of the construct across various disciplines.
