To be sustainable and competitive in the current business environment, it is useful to understand users’ sentiment towards products and services. This critical task can be achieved via natural language processing and machine learning classifiers. This paper aims to propose a novel probabilistic committee selection classifier (PCC) to analyse and classify the sentiment polarities of movie reviews.

An Indian movie review corpus is assembled for this study. Another publicly available movie review polarity corpus is also involved with regard to validating the results. The greedy stepwise search method is used to extract the features/words of the reviews. The performance of the proposed classifier is measured using different metrics, such as F-measure, false positive rate, receiver operating characteristic (ROC) curve and training time. Further, the proposed classifier is compared with other popular machine-learning classifiers, such as Bayesian, Naïve Bayes, Decision Tree (J48), Support Vector Machine and Random Forest.

The results of this study show that the proposed classifier is good at predicting the positive or negative polarity of movie reviews. Its performance accuracy and the value of the ROC curve of the PCC is found to be the most suitable of all other classifiers tested in this study. This classifier is also found to be efficient at identifying positive sentiments of reviews, where it gives low false positive rates for both the Indian Movie Review and Review Polarity corpora used in this study. The training time of the proposed classifier is found to be slightly higher than that of Bayesian, Naïve Bayes and J48.

Only movie review sentiments written in English are considered. In addition, the proposed committee selection classifier is prepared only using the committee of probabilistic classifiers; however, other classifier committees can also be built, tested and compared with the present experiment scenario.

In this paper, a novel probabilistic approach is proposed and used for classifying movie reviews, and is found to be highly effective in comparison with other state-of-the-art classifiers. This classifier may be tested for different applications and may provide new insights for developers and researchers.

The proposed PCC may be used to classify different product reviews, and hence may be beneficial to organizations to justify users’ reviews about specific products or services. By using authentic positive and negative sentiments of users, the credibility of the specific product, service or event may be enhanced. PCC may also be applied to other applications, such as spam detection, blog mining, news mining and various other data-mining applications.

The constructed PCC is novel and was tested on Indian movie review data.

The purpose of this study was to investigate if institutional stress is related to job performance among hospital employees, and if institutional stress is fully or partly mediated by motivational resources with regards to the relation with job performance.

A self-completion survey was distributed to four public hospitals in Norway, and had a response rate of 40% (N = 9,162). Structural equation modelling was conducted on two groups of hospital employees with (N = 795) and without (N = 8,367) managerial responsibilities.

Institutional stress was negatively related to job performance for hospital employees without managerial responsibilities. The motivational resources autonomy, competence development and social support partly mediated the relationship between institutional stress and job performance in the group of employees without managerial responsibilities. In the leader group, the motivational resources fully mediated the relationship between institutional stress and job performance. Social support from leaders had a non-significant influence on job performance in both groups.

The main limitation with this study is its cross-sectional design.

The study enables us to extend how work-related stress is related to job performance and the mediating role of the job resources autonomy, competence development and social support. The focus on productivity, and top management’s wish to improve hospital performance, may have unintended consequences, leading to a gap between managerial and clinical worldviews and understanding of goals, policies, values and prioritizing. This can lead to institutional stress. The findings of this study suggest that institutional stress has negative effects on hospital employees’ work motivation and job performance.

Recovery for residents who experience co-occurring problems and live in supported housing takes place in everyday contexts. This study aims to explore residents’ self-reported recovery and quality of life and examine the relationships between these factors and issues in supported housing.

A cross-sectional study was conducted at 21 supported housing sites in six cities across Norway. A total of 104 residents (76 men and 28 women) responded to measures of recovery (Recovery Assessment Scale – Revised), life satisfaction (Manchester Short Assessment of Quality of Life), affect (single items), staff support (Brief INSPIRE) and sense of home (single items).

Linear regression analyses indicated associations between recovery and staff support (B = 0.01, 95% CI = 0.01-0.02, ß = 0.39), housing satisfaction (B = 0.15, 95% CI = 0.07-0.22, ß = 0.38), sense of home (B = 0.23, 95% CI = 0.14-0.32, ß = 0.49) and satisfaction with personal economy (B = 0.11, 95% CI = 0.05-0.17, ß = 0.33). Similarly, associations were found between life satisfaction and staff support (B = 0.03, 95% CI = 0.02-0.04, ß = 0.46), housing satisfaction (B = 0.63, 95% CI = 0.46-0.80, ß = 0.60), sense of home (B = 0.65, 95% CI = 0.42-0.87, ß = 0.51) and satisfaction with personal economy (B = 0.34, 95% CI = 0.19-0.50, ß = 0.39).

The findings imply that core issues in supported housing, namely, staff support, housing satisfaction, sense of home and satisfaction with personal economy, are associated with recovery and quality of life.

Prisoners’ oral health is an often overseen, yet important aspect of the general health of prisoners. To develop effective measures to improve the situation, it is important to get an overview of existing research. The purpose of this study is to examine and analyse existing research on oral health of prisoners and provide a thorough understanding of prisoners’ oral health and related factors.

Due to relatively few scientific papers on prisoners’ oral health, an integrative review was chosen. Integrative reviews allow for the inclusion of diverse methodologies. A literature search was conducted, followed by an assessment of the quality of the studies by using the Mixed Methods Appraisal Tool. Thematic analysis was used to analyse the studies.

The few studies addressing European prisoners’ oral health in the last 21 years differ in design and methodology. The results from this review indicate that prisoners’ oral health is a complex phenomenon and should be understood from both individual and organisational perspectives. More research is needed to bridge the gap in the literature on prisoners’ oral health.

To the best of the authors’ knowledge, this is the first literature review on European prisoners’ oral health.

Since more than 450 million people worldwide suffer from mental disorders, interventions that promote mental health have been called for. Mindfulness-based coping (MBC) is an intervention based on coping skills from cognitive behavioral therapy integrating mindfulness practices. The aim of this study was to examine the effectiveness of the MBC program for psychiatric outpatients. The study employed a mixed research method with a qualitative approach using semi-structured patient interviews and clinical assessments from patients' therapists and a quantitative approach using instruments measuring mindful coping, mental ill health, and life satisfaction. The study sample included 38 psychiatric outpatients from a district psychiatric outpatient service in Norway. Results suggested that although use of the different skills varied, participants had a positive experience with the program and positive changes in psychological functioning were observed. Findings provide knowledge regarding the design of interventions integrating mindfulness to promote more adequate psychological coping.

Engagement in meaningful occupations and being included as full citizens of the community, is essential in everyday life, and may be of considerable relevance for recovery and quality of life. However, persons with co-occurring substance use and mental health problems experience extensive obstacles to engagement in occupations and citizenship. The relationship between objective measures of occupational status and subjective experiences of occupational meaningfulness, citizenship and recovery, is scarcely researched in the context of co-occurring problems. As such, the purpose of this study is to examine associations between occupational status, occupational meaningfulness, citizenship and recovery and quality of life and to examine the roles of occupational meaningfulness and citizenship as possible mediators between occupational status and recovery and quality of life.

The study used a cross-sectional design with a sample of 104 residents at supported housing sites across six Norwegian cities.

Linear regression analyzes indicated that occupational status was significantly associated with the citizenship domains caring for others and community participation and with the quality of life measure positive affect. Occupational meaningfulness and citizenship were significantly associated with different domains of recovery and quality of life. Furthermore, mediation analyzes showed that the relationship between occupational status and recovery and quality of life was mediated by caring for others and community participation.

The results suggest that emphasizing opportunities for occupational meaningfulness and citizenship in practice may have positive implications for recovery among persons with co-occurring problems.

Prisoners have poorer oral health than the general population. Good oral health is essential for both social and physical well-being. For prisoners, poor oral health is also related to drug use after release, whereas good oral health is related to successful reintegration into society. The purpose of this study was twofold: to examine the effect of an intervention based on motivational interviewing (MI) on prisoners’ oral health-related behavior and to assess if the intervention is a good fit for this population.

In total, 16 prisoners in a Norwegian prison were offered a brief MI-based intervention focusing on changing their oral health-related behavior. An oral examination was also performed and the prisoners received a small package containing oral hygiene aids. Two weeks later, a second oral examination and a semi-structured interview were conducted to explore the effect of the intervention and examine the prisoners’ responses to the intervention. Qualitative data analyzes were guided by thematic analysis.

The findings indicate that the intervention had positive effects on both the prisoners’ motivation to use oral health-related behavior and their performance of oral health-related behavior. The findings also indicate that the intervention was well adapted to the target population.

This is one of the first studies that explore the effect of an intervention in improving prisoners’ oral health and bridges a knowledge gap in the literature. The findings may increase the understanding of how dental services should be organized and offered to provide dental health care to this vulnerable group.

There is substantial research on the experiences, needs and well-being of unaccompanied refugee adolescents, but less is known about existential aspects of their lives. The purpose of the current study is to explore existential meaning-making among unaccompanied refugee children.

The informants in this study are young unaccompanied refugees (n = 30) living in Norway, and young Norwegians (n = 46). The authors undertook a secondary analysis of in-depth qualitative refugee interview data and a quantitative analysis of questionnaire data from Norwegian informants.

Both the refugee youths and the Norwegian youths expressed that social relationships and connections to others were most important for meaning. Moreover, both groups emphasized the importance of relatedness and generativity, i. e. commitment to worldly affairs beyond one’s immediate needs. The main differences between the two groups were related to the significance attached to religion and to loneliness.

The comparison between the two groups is only possible to some degree. Secondary analyses have some limitations, as well as strengths.

The findings may be useful for supporting young refugees, as they provide insights into less-studied aspects of their lives.

The originality of this study lies in the focus on and broad interpretation of meaning, of secondary data analyses, and of comparisons between youths that are refugees versus non-refugees.

The purpose of this paper is to examine the impact of entrepreneurship education (EE) in the form of a business planning course on students' career intentions and preferences. While there is extensive research in which traditional survey scales have been applied to study students' entrepreneurial intentions, this study takes a novel approach by extending the construct of entrepreneurial intention to include preferences for intrapreneurship and team entrepreneurship. Furthermore, the use of conjoint analysis captures students' unconscious decision-making processes when presented with different career opportunity scenarios, thereby overcoming many of the limitations of self-reported survey measures.

The study uses a quasi-experimental design with a novel application of conjoint analysis in EE research. A two-part survey combining a traditional questionnaire with conjoint analysis was distributed to students enrolled in a business planning course at two campuses of a Norwegian university, resulting in 99 matched pre- and post-test responses.

Two main findings arise from the study. First, there is a significant decrease in entrepreneurial intention among students in the EE course. Second, the conjoint analysis contributes to a better understanding of this decrease by illustrating how students shift their career preferences from entrepreneurship to employment during the EE course. This suggests that EE provides a space for students' career reflections where they can explore, commit to and reconsider entrepreneurship as a career.

A limitation of the study is that it focuses on a small sample of undergraduate students from two campus locations in Norway. Thus, further investigation is still necessary to establish whether the findings are valid in other contexts. The research has implications for higher educational institutions, policymakers and researchers in the field of EE.

The study contributes with a novel perspective on EE as a trigger for career reflection, a perspective that is important for educators teaching EE courses, as well as for higher education institutions who decide to implement EE in study programmes.

By focusing on the development of students' career preferences through conjoint analysis, the study expands knowledge on the impact of EE on students' careers, while also accentuating the value of the application of conjoint analysis in research on EE.

The purpose of this paper is to explore how energy companies discursively construct climate change when integrating it into their overall business strategy.

This linguistic study uses a quantitative/qualitative approach to investigate three instances of recent climate disclosure, climate strategy reports, by the energy majors Statoil (now Equinor), Suncor Energy and Total. The qualitative analysis focuses on how keywords and expressions function in their immediate linguistic context. The discussion takes the socio-political and business context of the companies into account.

The paper finds that the reports discursively construct climate change in different ways. Total presents climate change primarily as a responsibility the company is ready to take on; Suncor Energy presents it primarily as a business risk; and Statoil as a business opportunity. In the material as a whole, however, the risk representation is the most prevalent.

The material is relatively modest; however, the three reports represent the first comprehensive accounts of how energy players fit climate considerations into their overall strategy. The analysis is based on three search terms (responsibility, risk and opportunity). Further studies should include a broader range of words that may be semantically related to each approach.

The study can inform corporate strategy discussions and indicate the rhetorical implications of discourse-related choices in climate disclosure.

The study deals with very recent corporate disclosure involving an emerging discourse, climate strategy reporting. As the reports represent responses to investor engagement, the findings should also be relevant for studies involving stakeholder perceptions.
