Financial incentives and study duration in higher education

The current paper investigates to which extent students in higher education respond to financial incentives by adjusting their study behavior. Students in Norway who completed certain graduate study programs between 1991 and 1995 on stipulated time were entitled to a restitution (of approximately 3,000 USD) from the Norwegian State Educational Loan Fund. Using a difference-in-difference approach, we find that the fraction of students graduating on time during the reform period increased by 10 percent, relative to a base probability of about 25 percent. The estimated effect for fully treated students (students who were aware of the reform from the start of their studies) is much higher, at 50 percent.

Place-based learning : making use of nature in young children's learning in rural areas in Norway and Scotland

Two case studies in outdoor learning from Norway and Scotland illustrate ways in which communities can help in developing and shaping their Early Childhood Education and Care (ECEC) services and schools. Presented in their geographical and historical context, including a descriptive analysis of their preschool and education systems, it is argued that their creative use of rural environments in the learning of young children illustrate the power of partnership with communities. However, creative “democratic experimentalism” of this kind requires flexibility within the curriculum and a supportive educational culture.publishedVersio

The Reporting of End of Life and Module D Data and Scenarios in EPD for Building level Life Cycle Assessment

This paper identifies the need for Environmental Product Declarations (EPD) to provide End of Life (EoL) and Module D data for products for use in building level Life Cycle Assessment (LCA). Although the provision of data for EN 15804 Modules A4-D is not currently mandatory for EPD, many currently report some or all of these. This paper provides an overview of the existing reporting of the end of life (Modules C1-4) and Module D and the types of scenarios used in European EPD. Using examples from existing EPD for two product groups, this paper examines the variation in approaches to scenarios for Module C and D. It explores the difficulties brought by this variation and discusses benefits from using default national scenarios at end of life, but additionally considers the advantages of providing alternative EoL scenarios for products to promote the circular economy

A Cambrian–Ordovician boundary section in the Rafnes–Herøya submarine tunnel, Skien–Langesund District, southern Norway

Rock specimens and contained fossils collected in 1976 from a submarine tunnel driven between Herøya and Rafnes in the Skien–Langesund area of southern Norway, have been restudied. The contained fossils include olenid and agnostoid trilobites, graptolites and brachiopods, groups described in detail for the first time from the area and documenting a Cambrian–Ordovician boundary section unique in the district where the upper Cambrian Alum Shale Formation is elsewhere overlain by the Middle Ordovician Rognstranda Member of the Huk Formation (Kundan in terms of Baltoscandian chronostratigraphy). The hiatus at the base of the Huk Formation is thus smaller in the section described herein, beginning at a level within rather than below the Tremadocian. Estimated thickness of the Alum Shale includes 10–12 m of Miaolingian and 20–22 m of Furongian strata with trilobite zones identified, and a Tremadocian section of 8.1 m identified by species of the dendroid graptolite Rhabdinopora in the basal 2.6 m and Bryograptus ramosus at the top. The Tremadocian section is preserved in a postulated zone of synsedimentary subsidence along the Porsgrunn–Kristiansand Fault Zone, while at the same time there was extensive erosion across an emergent, level platform elsewhere in the Skien–Langesund District and the southern part of the Eiker–Sandsvær District to the north. Aspects of stratigraphy and tectonics are highlighted together with a discussion on the Cambrian– Ordovician boundary locally and worldwide

Maternal Awareness of Adolescent Bullying Victimization in a Low-Income Context

The published manuscript is available at EurekaSelect via https://doi.org/10.2174/2210676609666190808094820.Background: Adolescents and parents often disagree about the perception of bullying victimization since adults tend to underestimate its occurrence. Objective: This study identifies factors that can influence maternal perception of bullying victimization experienced by her son/daughter in the past 12 months. Methods: This cross-sectional study involved a representative sample of in-school adolescents (n=669, 11-15-years) living in Itaboraí city, Brazil (mean age±SE: 13.01±0.07 years; 51.7% females). A 3-stage probabilistic sampling procedure (random selection of census units, eligible households and target child) generated sampling weights. Trained lay interviewers individually applied semi-structured questionnaires to mothers and adolescents in the households. Multivariable logistic regression analysis examined factors potentially influencing maternal perception of bullying victimization experienced by her son/daughter: adolescent gender and age, adolescent self-perceived bullying victimization, exposure to severe physical punishment by parents, internalizing/externalizing behaviour problems identified by the Youth Self-Report/YSR, maternal education and maternal anxiety/depression identified by the 20-item Self-Reporting Questionnaire/SRQ-20. Results: Univariable logistic regression analysis identified a strong association between adolescent self-perceived bullying victimization and maternal perception of bullying victimization experienced by her son/daughter. Multivariable models showed that adolescent perception influenced maternal perception when adolescents had no clinical internalizing behaviour problems and when mothers had higher education. Conclusion: Anxious/depressive adolescents may hide victimization incidents, while those with no problems probably reveal these incidents to the mother. Considering that maternal low education is an indicator of low socioeconomic status, which is associated with multiple stressors, less educated mothers may be more likely to interpret these incidents as a common part of growing-up

Do adolescents exposed to peer aggression at school consider themselves to be victims of bullying? The influence of sex and age

Introduction Exposure to peer aggression (PA) and bullying victimization (BV) are both expressions of peer victimization. Objectives In four age-sex groups, (1) Can exposure to PA and BV be considered distinct experiences? (2) To what extent do adolescents exposed to PA consider themselves bullying victims? and (3) What is the effect on BV of the number of PA events experienced? Methods This cross-sectional study evaluated a probabilistic community-based sample of 669 adolescents (11-15 years, 51.7% girls). A three-stage probabilistic sampling plan involved random selection of census units, eligible households, and one target child per household selected. A 15-item scale investigated exposure to PA events (physical aggression, verbal harassment, social manipulation) occurring more than once in the past six months. BV occurring more than once a week or most days in the past six months was investigated after presenting respondents with a BV definition that required them to feel harmed by their victimization experiences. Results Adolescents exposed to PA and/or BV reported PA only (76.2%), BV only (4.7%), and both (19.1%). Rates of BV among those exposed to PA were as follows: 11-to-12-year-old boys (22.7%), 13-to-15-year-old boys (9.7%), 11-to-12-year-old girls (46.5%), and 13-to-15-year-old girls (13.2%). Multiple logistic regression analysis (outcome = BV) found a significant interaction between PA, age, and sex. PA events had a significant effect on BV for all except older girls. Conclusion Exposure to PA and BV are different constructs; few older boys exposed to PA consider themselves bullying victims; and older girls are less affected by PA when it comes to BV

Antithrombotic treatment after stroke due to intracerebral haemorrhage

BACKGROUND: This is an update of the Cochrane Review last published in 2017. Survivors of stroke due to intracerebral haemorrhage (ICH) are at risk of major adverse cardiovascular events (MACE). Antithrombotic (antiplatelet or anticoagulant) treatments may lower the risk of ischaemic MACE after ICH, but they may increase the risk of bleeding. OBJECTIVES: To determine the overall effectiveness and safety of antithrombotic drugs on MACE and its components for people with ICH. SEARCH METHODS: We searched the Cochrane Stroke Group Trials Register (5 October 2021). We also searched the Cochrane Central Register of Controlled Trials (CENTRAL: the Cochrane Library 2021, Issue 10), MEDLINE Ovid (from 1948 to October 2021) and Embase Ovid (from 1980 to October 2021). The online registries of clinical trials searched were the US National Institutes of Health Ongoing Trials Register ClinicalTrials.gov (clinicaltrials.gov) and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (5 October 2021). We screened the reference lists of included randomised controlled trials (RCTs) for additional, potentially relevant RCTs. SELECTION CRITERIA: We selected RCTs in which participants with ICH of any age were allocated to a class of antithrombotic treatment as intervention or comparator. DATA COLLECTION AND ANALYSIS: In accordance with standard methodological procedures recommended by Cochrane, two review authors assessed each selected RCT for its risk of bias and extracted data independently. The primary outcome was a composite of MACE, and secondary outcomes included death, individual components of the MACE composite, ICH growth, functional status and cognitive status. We estimated effects using the frequency of outcomes that occurred during the entire duration of follow‐up and calculated a risk ratio (RR) for each RCT. We grouped RCTs separately for analysis according to 1) the class(es) of antithrombotic treatment used for the intervention and comparator, and 2) the duration of antithrombotic treatment use (short term versus long term). We pooled the intention‐to‐treat populations of RCTs using a fixed‐effect model for meta‐analysis, but used a random‐effects model if RCTs differed substantially in their design or there was considerable heterogeneity (I(2) ≥ 75%) in their results. We applied GRADE to assess the certainty of the evidence. MAIN RESULTS: We identified seven new completed RCTs for this update, resulting in the inclusion of a total of nine RCTs based in secondary care, comprising 1491 participants (average age ranged from 61 to 79 years and the proportion of men ranged from 44% to 67%). The proportion of included RCTs at low risk of bias, by category was: random sequence generation (67%), allocation concealment (67%), performance (22%), detection (78%), attrition (89%), and reporting (78%). For starting versus avoiding short‐term prophylactic dose anticoagulation after ICH, no RCT reported MACE. The evidence is very uncertain about the effect of starting short‐term prophylactic dose anticoagulation on death (RR 1.00, 95% CI 0.59 to 1.70, P = 1.00; 3 RCTs; very low‐certainty evidence), venous thromboembolism (RR 0.84, 95% CI 0.51 to 1.37, P = 0.49; 4 RCTs; very low‐certainty evidence), ICH (RR 0.24, 95% CI 0.04 to 1.38, P = 0.11; 2 RCTs; very low‐certainty evidence), and independent functional status (RR 2.03, 95% CI 0.78 to 5.25, P = 0.15; 1 RCT; very low‐certainty evidence) over 90 days. For starting versus avoiding long‐term therapeutic dose oral anticoagulation for atrial fibrillation after ICH, starting long‐term therapeutic dose oral anticoagulation probably reduces MACE (RR 0.61, 95% CI 0.40 to 0.94, P = 0.02; 3 RCTs; moderate‐certainty evidence) and probably reduces all major occlusive vascular events (RR 0.27, 95% CI 0.14 to 0.53, P = 0.0002; 3 RCTs; moderate‐certainty evidence), but probably results in little to no difference in death (RR 1.05, 95% CI 0.62 to 1.78, P = 0.86; 3 RCTs; moderate‐certainty evidence), probably increases intracranial haemorrhage (RR 2.43, 95% CI 0.88 to 6.73, P = 0.09; 3 RCTs; moderate‐certainty evidence), and may result in little to no difference in independent functional status (RR 0.98, 95% CI 0.78 to 1.24, P = 0.87; 2 RCTs; low‐certainty evidence) over one to three years. For starting versus avoiding long‐term antiplatelet therapy after ICH, the evidence is uncertain about the effects of starting long‐term antiplatelet therapy on MACE (RR 0.89, 95% CI 0.64 to 1.22, P = 0.46; 1 RCT; moderate‐certainty evidence), death (RR 1.08, 95% CI 0.76 to 1.53, P = 0.66; 1 RCT; moderate‐certainty evidence), all major occlusive vascular events (RR 1.03, 95% CI 0.68 to 1.55, P = 0.90; 1 RCT; moderate‐certainty evidence), ICH (RR 0.52, 95% CI 0.27 to 1.03, P = 0.06; 1 RCT; moderate‐certainty evidence) and independent functional status (RR 0.95, 95% CI 0.77 to 1.18, P = 0.67; 1 RCT; moderate‐certainty evidence) over a median follow‐up of two years. For adults within 180 days of non‐cardioembolic ischaemic stroke or transient ischaemic attack and a clinical history of prior ICH, there was no evidence of an effect of long‐term cilostazol compared to aspirin on MACE (RR 1.33, 95% CI 0.74 to 2.40, P = 0.34; subgroup of 1 RCT; low‐certainty evidence), death (RR 1.65, 95% CI 0.55 to 4.91, P = 0.37; subgroup of 1 RCT; low‐certainty evidence), or ICH (RR 1.29, 95% CI 0.35 to 4.69, P = 0.70; subgroup of 1 RCT; low‐certainty evidence) over a median follow‐up of 1.8 years; all major occlusive vascular events and functional status were not reported. AUTHORS' CONCLUSIONS: We did not identify beneficial or hazardous effects of short‐term prophylactic dose parenteral anticoagulation and long‐term oral antiplatelet therapy after ICH on important outcomes. Although there was a significant reduction in MACE and all major occlusive vascular events after long‐term treatment with therapeutic dose oral anticoagulation for atrial fibrillation after ICH, the pooled estimates were imprecise, the certainty of evidence was only moderate, and effects on other important outcomes were uncertain. Large RCTs with a low risk of bias are required to resolve the ongoing dilemmas about antithrombotic treatment after ICH

The stroke oxygen pilot study: a randomized control trial of the effects of routine oxygen supplementation early after acute stroke--effect on key outcomes at six months

Introduction: Post-stroke hypoxia is common, and may adversely affect outcome. We have recently shown that oxygen supplementation may improve early neurological recovery. Here, we report the six-month outcomes of this pilot study. Methods: Patients with a clinical diagnosis of acute stroke were randomized within 24 h of admission to oxygen supplementation at 2 or 3 L/min for 72 h or to control treatment (room air). Outcomes (see below) were assessed by postal questionnaire at 6 months. Analysis was by intention-to-treat, and statistical significance was set at p#0.05. Results: Out of 301 patients randomized two refused/withdrew consent and 289 (148 in the oxygen and 141 in the control group) were included in the analysis: males 44%, 51%; mean (SD) age 73 (12), 71 (12); median (IQR) National Institutes of Health Stroke Scale score 6 (3, 10), 5 (3, 10) for the two groups respectively. At six months 22 (15%) patients in the oxygen group and 20 (14%) in the control group had died; mean survival in both groups was 162 days (p= 0.99). Median (IQR) scores for the primary outcome, the modified Rankin Scale, were 3 (1, 5) and 3 (1, 4) for the oxygen and control groups respectively. The covariate-adjusted odds ratio was 1.04 (95% CI 0.67, 1.60), indicating that the odds of a lower (i.e. better) score were non-significantly higher in the oxygen group (p= 0.86). The mean differences in the ability to perform basic (Barthel Index) and extended activities of daily living (NEADL), and quality of life (EuroQol) were also non-significant. Conclusions: None of the key outcomes differed at 6 months between the groups. Although not statistically significant and generally of small magnitude, the effects were predominantly in favour of the oxygen group; a larger trial, powered to show differences in longer-term functional outcomes, is now on-going.
