- Ontological analysis facilitates microarray data interpretation. We describe new ontological analysis methods which, unlike existing approaches, are threshold-free and statistically powerful. We perform extensive evaluations and introduce a new concept, detection spectra, to characterize methods. We show that different ontological analysis methods exhibit distinct detection spectra, and that it is critical to account for this diversity. Our results argue strongly against the continued use of existing methods, and provide directions towards an enhanced approach.

Positioning controversy in environmental and sustainability education

- This study delves into the intricate dynamics of controversial issues in environmental education, challenging conventional notions. It explores the relationship between “controversy” and the field of environmental education, elucidating its multifaceted dimensions in and ambitions of teaching practice. In dialogue with previous research and based on our empirical study, we contend that controversy’s existence transcends the mere content of education and extends to its perceived fundamental core and normative underpinnings. We argue that controversy, including controversial sustainability issues (CSIs), is not confined to educational content alone but encompasses the purposes of education. We propose that controversy in educational encounters cannot be neatly categorized as a fixed, predictable social product and is not solely dependent on student interaction. This challenges earlier research positions that linked controversy to the presence of debate or dissensus in a subject area. Our study challenges the traditional understanding of controversy, highlighting its partial spontaneity and unpredictability in teaching. This contrasts previous positions that emphasized the epistemic dimension of controversy. Instead, our findings suggest that controversy plays an active role in the process of self-formation or subjectification in relation to any content.

- Background. Recently, the Occupational Balance Questionnaire developed in Sweden was translated into Norwegian. No studies to date have examined the measurement properties of the Norwegian version of this questionnaire. Aim. The study is aimed at examining the psychometric properties of the Norwegian version of the Occupational Balance Questionnaire, the OBQ11-N. Methods. Along with sociodemographic data, 180 occupational therapy students enrolled at two Norwegian universities completed the OBQ11-N as well as one question each related to health and quality of life and some sociodemographic variables. Rasch analysis was employed for examining rating scale functioning, item and person validity, dimensionality, and differential item functioning. Results. Item categories were ordered, but there were potential gaps in the measurement of the construct. Person reliability was fair, whereas item reliability was low. Point biserial correlations were positive, indicating that all items contributed to the construct. Factor loadings were low for two items, and there were indices of a second underlying dimension and item redundancy. Many people were not aligned with the items, and some items functioned differently across various demographic variables. Conclusion and Significance. The OBQ11-N did not function as an adequate measure of occupational balance in a sample of students. Potentially, the detected measurement problems may be solved by adding more relevant items to a larger item pool, from which the best fitting items should be selected.

- Background: Parents with small children constitute a vulnerable group as they have an increased risk of sick leave due to stress-related disorders compared to adults without children. It has been shown that mothers and fathers to small children together spend more time in paid work than any other group, which could create negative stress and an experience of low occupational balance. Aim: The aim of this study was to examine associations between organisational factors and occupational balance among parents with small children in Sweden. Methods: Data were collected by a survey including questions about occupational balance, organisational factors and age, sex, employment rate, work position, monthly household income, number of children at home, separation/divorce last five years and overtime. The total number of parents included in this study was 718 (490 mothers and 228 fathers). Logistic regression models were applied to examine the odds ratios for occupational balance in relation to organisational factors. Results: Parents who experienced positive attitudes towards parenthood and parental leave among colleagues and managers were more likely to experience high occupational balance than parents who experienced negative or neutral attitudes. Having a clear structure for handover when absent from work was also strongly associated with high occupational balance. Conclusions : The result of the present study indicates that some organisational factors could be important for the occupational balance of parents with small children.

- Objective To investigate potential risk factors behind the increased incidence of necrotising enterocolitis (NEC) in Swedish extremely preterm infants.Design Registry data from two population-based national cohorts were studied. NEC diagnoses (Bell stage >= II) were validated against hospital records.Patients All liveborn infants <27 weeks of gestation 2004-2007 (n=704) and 2014-2016 (n=895) in Sweden.Main outcome measures NEC incidence.Results The validation process resulted in a 28% reduction of NEC cases but still confirmed a higher NEC incidence in the later epoch compared with the earlier (73/895 (8.2%) vs 27/704 (3.8%), p=0.001), while the composite of NEC or death was lower (244/895 (27.3%) vs 229/704 (32.5%), p=0.022). In a multivariable Cox regression model, censored for mortality, there was no significant difference in early NEC (0-7 days of life) between epochs (HR=0.9 (95% CI 0.5 to 1.9), p=0.9), but being born in the later epoch remained an independent risk factor for late NEC (>7 days) (HR=2.7 (95% CI 1.5 to 5.0), p=0.001). In propensity score analysis, a significant epoch difference in NEC incidence (12% vs 2.8%, p<0.001) was observed only in the tertile of infants at highest risk of NEC, where the 28-day mortality was lower in the later epoch (35% vs 50%, p=0.001). More NEC cases were diagnosed with intramural gas in the later epoch (33/73 (45.2%) vs 6/26 (23.1%), p=0.047).Conclusions The increase in NEC incidence between epochs was limited to cases occurring after 7 days of life and was partly explained by increased survival in the most extremely preterm infants. Misclassification of NEC is common.

- IntroductionOccupational balance (OB) is related to many health indicators, including quality of life. The Occupational Balance Questionnaire (OBQ11) was developed to measure OB, and to date, no Arabic translations of the questionnaire exist. The aim of the study was to describe the translation process of OBQ11 to Arabic and to evaluate its content validity, internal consistency, construct validity, and convergent validity.MethodsOBQ11 was translated to Arabic (OBQ11-A) following standard guidelines. Content validity feedback was obtained from ten Arabic-speaking occupational therapists and in a cognitive debriefing with seven volunteers. In addition, OBQ11-A and the Family Quality of Life Survey-2006 were administered to 67 Arabic-speaking participants from a larger study about OB among parents.ResultsHigh level of agreement was found on the content of OBQ11-A from the occupational therapists. Cognitive debriefing interviews indicated that OBQ11-A was easy to understand. Cronbach?s alpha for the total OBQ11-A score was 0.864 indicating good internal consistency. Exploratory factor analysis showed acceptable factor loadings for all items. The total scores showed positive statistically significant associations with Family Quality of Life Scores (r = 0.561, p < 0.001).ConclusionsOBQ11-A may prove useful for assessing OB in Arabic-speaking populations. Further research is needed to establish its reliability.
