Abstract
Purpose
Homelessness and psychoactive substance (PS) use are both determinants of physical and mental ill health, with the homeless population using, and dying of PSs more frequently than the general population. However, there is a gap in research on the real-world implications psychoactive substance use (PSU) has on the homeless population. This study aims to explore the experiences of PSU from the perspective of homeless users.
Design/methodology/approach
Purposive sampling was adopted to recruit participants and semi-structured interviews collected data from participants, with interpretive phenomenological analysis (IPA) generating common themes from the data gathered.
Findings
Four participants were interviewed. The themes generated were family and close relationships; cyclical patterns; mistrust in people and services; and low self-worth.
Research limitations/implications
This study is limited by potential bias from researchers who built relationships with participants through the data collection process. Despite efforts to remove this bias, through reflexivity throughout data collection and analysis, some bias may be still present. The researchers saw the participants as vulnerable people who were striving to overcome adversity. Such conception of the participants is reflective of how the participants portrayed themselves. The small sample is suitable for IPA purposes. Of course, it could have been possible that if different participants had been recruited or more participants had been recruited, then there could have been different themes and findings. IPA prides itself on its idiographic focus.
Practical implications
More research is needed on a wider scale to assess the extent and cause of these issues. Increased education and dissemination of research such as this is required to break down stigma within the public and guide policy change in professional services.
Originality/value
This paper interpretatively presents themes generated by semi-structured interviews with four homeless PSUs. As such, these individuals are vulnerable and have faced adversity throughout life from both society and the services they use. Their vulnerability leads to a cycle of substance use and a feeling of low self-worth, which is perpetuated by the perceived views of those around them.

Abstract
Purpose
The purpose of this study is to collect the first empirical data on the cognitive state of elderly prisoners in Germany and to examine associations between cognitive function and sociodemographic, clinical and incarceration characteristics.
Design/methodology/approach
All prisoners aged 60 years and older of five prisons in North Rhine-Westphalia, Germany, were asked to participate. The cognitive screening instruments mini-mental state examination (MMSE) and the DemTect were used to assess global cognition. Executive functions were tested with the trail making test and the frontal-assessment-battery. The Patient Health Questionnaire (PHQ-9) was used to assess participants’ affective state.
Findings
The sample of this study consisted of 58 prisoners with a mean age of 65.52 years (standard deviation = 6.03); 82.8% are male. Using the MMSE with age- and education-corrected z-scores, 36.9% of the prisoners showed marginal or impaired global cognition scores. Using the DemTect, 41.4% of the prisoners were classified as being cognitively impaired. Up to 40% of the prisoners showed deficits in executive functioning and around 60% of the prisoners showed depressive symptoms. The correlation analysis revealed significant associations between cognitive scores and age (rho = –0.335, p = 0.014), education (rho = 0.309, p = 0.020), sentence duration (rho = 0.409, p = 0.007) and duration of current incarceration (rho = 0.302, p = 0.043). The DemTect total score was significantly associated with the PHQ-9 (rho = –0.335, p = 0.016).
Practical implications
A large group of the prisoners showed a higher prevalence of cognitive dysfunction than that observed in same-age people who are not incarcerated. Taken together, there is an urgent need for an adequate management of older cognitively impaired prisoners including routine cognitive testing and guidelines-oriented treatment of cognitive symptoms.
Originality/value
This study has several strengths. To the best of the authors’ knowledge, this is the first study examining the cognitive and affective state in a German prison population. The authors considered female and male prisoners, as well as different prison settings, representing a realistic prison sample. The authors used several neuropsychological instruments to get a more detailed insight into the older prisoners’ cognitive status while trying to consider the economy of time and possible attention deficits to prevent dropouts during testing.

Abstract
Purpose
Specific research related to the study of innovation barriers in service SMEs in the Latin American region is limited. The purpose of this paper is to investigate the effects that external environmental, financial and human barriers have on innovation activities, particularly, within the context of Mexican service SMEs.
Design/methodology/approach
Three hypotheses were formulated and tested using structural equation modelling. Data were collected through an instrument that was developed based on relevant constructs adapted from the literature. The instrument was validated using confirmatory factor analysis, Cronbach’s α test and the composite reliability index to ensure reliability of the theoretical model. The instrument was distributed among service SMEs in the Aguascalientes state of Mexico, from were 308 valid responses were obtained.
Findings
In general, the results indicate that all the three barriers investigated (i.e. external environmental, financial and human) hinder innovation in service SMEs, with the external environmental barrier being the most significant of the three.
Practical implications
The findings of this research can inform managers of service SMEs and policy makers when formulating and implementing strategies to reduce innovation barriers.
Originality/value
Evidence suggests that specific research related to the study of innovation barriers in service SMEs in the Latin American region is limited. This paper fills this research gap by expanding the limited body of knowledge in this field and providing further evidence on this phenomenon. The study also enables the distinctive characteristics of innovation barriers to be understood within a particular context, expanding in this way the body of knowledge on this field.

Abstract
Purpose
In an environment where business uncertainty is the norm, developing innovation capability in an organisation is increasingly important. The purpose of this paper is to investigate the effects that innovation capabilities have on the business performance of small- and medium-sized enterprises (SMEs) within the context of a regional developing and emerging economy of Mexico, in this case, Aguascalientes.
Design/methodology/approach
The approach of this study is quantitative. Four research hypotheses were formulated and tested using structural equation modelling (SEM). Data were collected through a questionnaire survey responded by 308 SMEs located in the Aguascalientes state of Mexico.
Findings
The results obtained show that innovation in products, processes, marketing and management has a positive and significant effect on the business return of Mexican SMEs.
Originality/value
The paper complements the limited body of knowledge currently existent in the SMEs innovation literature, particularly when compared to that of large organisations. Similar works in other settings have provided mixed results in regards to the effects that innovation capabilities have on the business performance of SMEs. Thus, this paper offers a refined understanding and validation of the relationship between innovation capabilities and business performance, especially within the context of SMEs, and insights into some of the innovation aspects that managers may consider when formulating the strategies of their organisations. Finally, it enables such relationship to be understood within a particular situation, contributing in this manner to expand the body of knowledge in the innovation field.

Abstract
Purpose
The purpose of this paper is to extend prior supply chain research by describing the process of innovation knowledge increase in supply chain network. More specifically, this study investigates the role of network density, and views the knowledge increase as the process of knowledge diffusion and knowledge innovation.
Design/methodology/approach
A multi-agent model, which demonstrates the process of knowledge increase in supply chain network, was established, and simulated by using NetLogo simulation platform.
Findings
The results indicate that the network density will promote the knowledge increase of the supply chain when it is high or low. In the meantime, these results show that the inhibition of knowledge diffusion and knowledge innovation will appear when network density is moderate.
Originality/value
Although previous research has identified the importance of knowledge increase in promoting sustainable development of supply chain, far less attention was given to the study of the effect of network structure on the knowledge increase in supply chain. This study thus fulfills the research gap by providing a description of the process of knowledge increase with the consideration of network density. The conclusion is of great significance for the choice of network density for sustainable development of supply chain.
