This study aims to assess the potency and dose of Δ-9-Tetrahidrocannabinol (THC) and Cannabidiol (CBD) in cannabis joints. This will enable better estimates of the degree of exposure in a user and contribute towards a better understanding of potential harmful effects.

Analysis of intact joints confiscated by law enforcement on the street in the autonomous region of Castilla y León (Spain) during the years 2017–2019.

This study analysed THC, CBN and CBD in marijuana joints (N = 744). Joints contain cannabis and tobacco (N = 729), had a median net weight 0.69 g (IQR = 0.28); concentration THC median was 6.30%(IQR = 4.51) and THC median dose 42 mg (IQR = 32.75). A total of 35.5% mixed joints contained CBN – median percentage 0.61% (IQR = 0.51). CBD was detected 10.3% of mixed joints – median percentage 0.13% (IQR = 0.12) and median dose 1 mg (IQR = 0.92). CBD/THC ratio presented median value of 0.02 (IQR = 0.02). The samples analysed comprised pure cannabis joints (N = 15), with THC median 11.86% (IWR = 6.30) or median dose of 118 mg.

The study found high values for concentration and dose of THC and CBD in cannabis joints, warning of high exposures for the user and associated potential consequences. The results obtained contribute new perspectives on the definition of a standard cannabis unit.

The aim of this paper is to determine chemical and sensory differences of between craft and industrial/or commercial beers. Beer market is nowadays booming and consumers are in the search of new and healthier products.

Here, commercial and craft beers were chemically analyzed and sensory evaluated. Chemical analysis included pH, bitterness, color, total polyphenol content and antioxidant activity. Likewise, 40 sensory descriptors were evaluated by trained panelists, including visual, olfactory and gustatory attributes. In addition, an electronic nose (e-nose) was tested to determine its suitability to discriminate beer type and/or style according to their volatiles profile.

Craft beers presented higher values of color, bitterness and antioxidant activity when compared to commercial beers. Sensory descriptors showed craft beers to be associated with the highest scores in visual, olfactory and gustatory descriptors. Data from e-nose explained 97% of the total variability of the volatile compounds in the analyzed beers, indicating the suitability of this device to discriminate beer types.

Results are of interest for design of marketing and selling techniques for craft brewery managers. In addition, cheap and easy-managing device as e-nose resulted in a valuable tool to monitoring beer quality.

The aim of the present article is to decide the ideal number of warehouses for a food manufacturer in the north of Spain (Asturias) for the year 2000, and their ideal location in the Spanish Peninsula by cluster analysis. The stages followed are to comment first on the underlying assumptions of the study, then on the methodology and the structure of the program developed to solve the problem, as well as on their input and output files. How the cluster and cost are calculated is discussed and finally the solution to this real case is provided.

Numerous sustainability assessment tools are being created and applied in the higher education sector. In light of such diversity, there is a need to provide a common guideline for sustainability assessment which makes easier the comparison among universities. Using as a reference the Spanish university system, the main aim of this paper is to develop a multi-item quantitative tool for measuring sustainability performance at universities.

To accomplish this task, the first step was to review the literature on sustainability assessment in universities. After reviewing the literature, the authors found more than 1,000 items. The next step was to select those items which were able to fit to the Spanish university context. On this basis, the authors selected a total of 268 items. These items were discussed in a workshop with senior management members from eight Spanish universities with the aim of analyzing the validity and relevance of the items selected.

Then, the proposal for measuring sustainability in Spanish universities was composed of a total of 156 relevant items. In addition, these items were grouped according to seven different dimensions (corporate governance, students, staff, society, environment, companies and continuous improvement). Also, it is important to note that these items were not associated with political risk and they were linked to provide more reliable information to assess sustainability in universities.

Recent literature have stated that the existing tools specifically developed for assessing higher education institutions performance toward sustainability have some weaknesses. Then, one of the main contributions of this study has been the creation of a new multi-item quantitative tool aimed at measuring the integrated consideration of social, economic and environmental dimensions of sustainability in universities.

The purpose of this paper is to address issues of practicing social responsibility (SR) in small business, where SR implementation challenges are unique. The discussion examines the difficulties encountered by small business owners adopting SR practices, and the various strategies they learned in the process.

A total of 23 small business owner‐managers located in Western Canada were interviewed in‐depth, individually, and in groups. Group interviews were useful for validating and extending the themes and contradictions that arose in individual interviews, particularly in identifying the most common SR challenges and frustrations, and to compare individuals' learning patterns and diverse strategies of response.

The paper findings show that owners learned SR by working through three main areas of challenge within everyday sociomaterial practices: positioning SR commitments and affiliations; balancing diverse stakeholders with SR ideals and costs; and negotiating value conflicts within SR practice, as part of “becoming” a particular enterprise of SR engagement.

The paper suggests that SR may be most fruitfully studied by examining the traces of the networks, linkages, and boundaries formulated through everyday interactions, focusing not just on the social networks and information exchange among humans, but more deeply on the sociomaterial networks within which new practices such as SR emerge. Second, the paper underscores the importance of conceptualizing SR “learning” more in terms of practices that emerge through challenge and conflict than in acquisition and application of new knowledge and attitudes.

The purpose of this study is to improve the understanding of stakeholder engagement in the context of sustainability reporting (SR) for higher education institutions (HEIs), together with the materiality principle and stakeholder expectations.

This research uses an exploratory approach based on content analysis, a case study and descriptive and inferential statistics.

Three key findings come out of this research. First, the results indicate that HEIs use diverse criteria for grouping stakeholders and that stakeholder engagement is a heterogeneous process. Second, the expectations of internal stakeholders align with the material aspects of SR. Finally, among internal stakeholders, students and academics disagree on the prioritisation of some sustainability aspects, with non-academic staff adopting an intermediate position.

This analysis improves our knowledge of stakeholder engagement in HEIs. It helps to identify the relevant impacts of stakeholder engagement, enhances the quality of reporting and encourages a real dialogue with stakeholders.

The study examines stakeholder engagement and how the materiality principle is adopted by HEIs through SR. Furthermore, it compares these results with stakeholder expectations, considering the discrepancies between stakeholders. The results open the way to future research to explore the potential conflicts and collaborations between and within stakeholders to advance towards more sustainable institutions in the higher education sector.

The purpose of this paper is to analyse the internal and external factors related to the disclosure of environmental information in universities which reflect the actions carried out in these universities.

Taking as reference the first 200 universities in the Shanghai ranking, several factors associated with the degree of environmental information disclosure in universities – governance dimension, the relationship and participation of stakeholders, position and prestige as signs of the quality of the institution and cultural concern in the university’s country for the environment – are analysed.

The results obtained show that the size of the leadership team, stakeholder participation, the position of the university in rankings and cultural concern in the university’s country for the environment are determining factors in the university’s environmental actions and, consequently, in their disclosure. Other factors – such as the size of the university, the level of self-financing and financial autonomy – do not affect the disclosure of environmental information.

Scant research exists on the environmental commitments of universities; this paper aims to fill that gap. Their role as the main channel of research and as instructors of future professionals makes them points of reference in society. Research on university ranking has traditionally focussed on teaching and research results, but environmental issues are becoming increasingly important. This paper enumerates the factors that influence the dissemination of environmental information in the most prestigious universities. This research also provides an original approach by considering not only top-down but also bottom-up strategies through communication channels and the incidence of cultural factors.

Using a soft-hard continuum of drivers and barriers, this research seeks to explain wood companies' adoption of circular economy (CE) practices.

Multiple interviews, complemented by secondary documents and site observations were used to investigate three wood-based companies that have adopted CE practices. The 10R framework and soft-hard continuum are used to guide data analysis.

The adoption of 10R practices were explained by soft-factor incentives of leaders' values and vision and openness for innovation, all within a regulatory void, and eventually overcome hard-factor barriers of process development, supply chain capability and customer behaviours at product end-of-life.

Crucial for CE model adoption are leaders' positive attitudes, subsequently grown across the companies. The 10Rs are a prompt for CE practice adoption to capture and retain value and generate revenue. Collaboration across the supply chain, including customers and other value capture companies (e.g. repurposing companies), is essential to maximise value retention. Government should play an increased soft-factor incentive regulatory role and support CE practices to overcome hard-factor barriers.

This study contributes an explanation of CE adoption within a relatively unsupported context. Despite the regulatory void, CE practice adoption was driven by leader values. To achieve their vision and overcome the numerous barriers, suppliers and customers required a large investment in education. Indeed, customer behaviour, previously thought to be an incentive for CE adoption, is also identified as a barrier.

Research pertaining to African-American women in academe is scant. Narrowing the focus to a specific segment of this population, such as those in the professoriate, is even more limited. Much of the available scholarship responding to the realities of African-American women’s work and lives in higher education revolves around the emotional, cultural, professional, and epistemic violence endured at the intersections of multiple systems of oppression, and the ways in which these women cope and resist. Less is known beyond these various coping strategies. Literature that responds to the complexities of Christianity and privilege, particularly in regards to directives for institutional diversity remains inconsistently addressed. The ways in which multiple forms of the Judeo-Christian faith influence experiences within differing higher educational settings is limited. Investigating the materiality that occurs in the interstices of these differing, yet interrelated, conversations has significant import for multiple dimensions of Black higher education. The present chapter questions the potential influence Judeo-Christian African-American women faculty have on diverse student engagement at historically Black colleges and universities.

Regardless of the noteworthy growth in research and practice associating corporate social responsibility (CSR) with human resource management, little has been written in regard to one major dimension of CSR in small- and medium-sized enterprises (SMEs), as CSR policies and practices are directed toward employees. The purpose of this paper is to develop and test a conceptual framework connecting socially responsible human resource management (SRHRM) to competitive performance that fits small business.

In order to get empirical evidence, structural equation modeling technique was applied on the data from 481 Spanish SMEs.

Results confirm both the direct contribution of SRHRM to business competitiveness and the multiple effects resulting from including two variables of additional interest for the relationship under study: employee’s commitment and relational marketing.

One of the main research limitations is that the paper only reflects the perceptions of owners/managers of SMEs. Although it was believed that the respondents give reliable and accurate information about the way their firms are involved in CSR practices, there is a possibility that they might provide incorrect or incomplete information.

The relationships proposed have never been studied before in context of SMEs. This is a worthwhile endeavor, which makes an empirical contribution.
