The European flexicurity concept and the Dutch and Danish flexicurity models: How have they managed the Great Recession?
Authors: Bekker Sonja , Mailand Mikkel 
Published: September 2018

AbstractIn the mid‐2000s, the flexicurity concept was developed into a key EU policy concept. It drew its inspiration from the Danish and Dutch practices to combine labor market flexibility and security. However, the crisis' focus on bringing down national deficits and debts left little room to advance the concept. Lately, more emphasis has been placed on the need to take into consideration the social aspect of economic policy‐making. Current EU level documents see flexicurity as a guidance for structural reforms. However, the European flexicurity initiatives seem never to have had much impact in Denmark and the Netherlands. There are few accounts of the recent adjustment to the flexicurity models, be it at the EU or at national levels. Therefore, this article assesses the fate of flexicurity by scrutinizing its (adjusted) use as a political concept as well as a socio‐economic model. Although the Danish flexicurity model resembles the European flexicurity concept to a large extent, recent reforms have, overall, weakened rather than strengthened the flexicurity model. The Dutch flexicurity model has a narrower focus on normalizing atypical work, while recent reforms support this narrow flexicurity model. Meanwhile, the EU level concept has been changing every year, encompassing a growing number of issues.

BACKGROUNDRed blood cell (RBC) transfusion is a lifesaving process for patients with perioperative bleeding, but transfusion can cause adverse events. Effective utilization and management of blood products as a limited resource is essential when considering cost‐efficiency and patient safety.STUDY DESIGN AND METHODSWe analyzed the number of RBC units used during the hospitalization of patients who had undergone surgical procedures from 2002 to 2013 using National Health Insurance Service‐National Sample Cohort data, which include a total of 487,238 cases for 206 selected operations.RESULTSRBC units were used in 39,637 (8.1%) cases. A total of 60,815 RBC units were transfused with a mean of 0.13 units per patient overall and a mean of 1.53 units per case receiving RBC transfusion. In addition, 56.7% of the RBC units were transfused for females, and 60.1% of RBC units were transfused into patients aged 60 or older. RBC units were used most often in orthopedic surgeries (33.8%), followed by general surgeries (12.0%) and vascular surgeries (11.8%). The number of operations performed in the cohort increased from 27,690 in 2002 to 49,473 in 2013, and the mean number of RBC units used per operation also increased from 0.08 units in 2002 to 0.15 units in 2013.CONCLUSIONContinuous management for blood preparation and transfusion is needed for efficient utilization of blood. Periodic investigation on the use of blood products through nationwide studies could suggest data applicable to blood product preparation for various elective surgical operations.

AbstractThis paper uses detailed micro data on services exports at the firm–destination–service level to analyse the role of firm heterogeneity in shaping aggregate services exports in Belgium, France, Germany and Spain from 2003 to 2007. We decompose the level and the growth of aggregate services exports into different trade margins paying special attention to firm heterogeneity within countries. We find that the weak export growth of France is at least partly due to poor performance by small exporters. By contrast, small exporters are the most dynamic contributors to the aggregate exports of Belgium, Germany and Spain. Our results highlight the importance of firm heterogeneity in understanding aggregate export growth.

Published: September 2018

SummaryThe spread of many invasive plants could be facilitated by their presence in urban areas that may act as dispersal centres and by climate warming. Cortaderia selloana, pampas grass, is native to South America and raises considerable concern worldwide as an introduction. We used Maxent niche modelling, based on occurrence records and on a set of simulated occurrence points with high probability of presence in urbanised areas in France, where the species was introduced and is still planted. We calibrated the model with current climate data coupled with several habitat variables and used it to predict range shifts of C. selloana under four climate change scenarios (RCP) for 2060. The results were consistent with the known ecology of the species and showed that the most important variables that explain the current distribution in the introduced area were mean annual minimum temperatures, sandy habitats, disturbed habitats and urbanised areas. While the species already occupies large areas along the western and Mediterranean coasts, the models predicted an expansion northward and inland to the east under future climates. The area of suitable habitats could increase by up to 69% under the RCP 8.5 climate scenario in 2060 and by 116% with the extra occurrences in urban/suburban areas. This latter scenario suggests that areas like public and private gardens or urban parks, where the species is currently cultivated, could contribute to increase the invasion risk under climate warming. The results provide predictions of potential environments for the species, which can be helpful for anticipating its spread.
Transformational Leadership and Job Satisfaction: The Case of Secondary Education Teachers in Greece
Authors: Kouni Zacharo , Koutsoukos Marios , Panta Dimitra 
Published: September 2018

In international literature there are many documented studies which have shown the relationship between leadership and job satisfaction. Specifically, transformational leadership is highly associated with this important and positive work attitude, that is, job satisfaction. The interpretation in a school context is that the director should operate as transformational leader so as to produce better educational outcomes through teachers' job satisfaction. In Greece, little empirical research has been done to investigate the perceptions of teachers about the relationship between transformational leadership and job satisfaction of teachers. The purpose of the present study is to investigate the perceptions of teachers to the extent that transformational leadership contributes to job satisfaction. The selected research method is a combination of quantitative and qualitative methods, namely using the questionnaire and the interview. The sample consisted of 171 teachers from two types of educational institutions, secondary junior high schools and high schools, of a local directorate of secondary education. The survey results showed that teachers feel substantial satisfaction when the school principal acts as a transformational leader. Demographic variables, the type of school, and work experience, do not affect the views of teachers.

Authors: Eker Halime , Kaya Mehmet 
Published: September 2018

The aim of this research is to investigate the relationship between parental attitudes perceived by the students, self-compassion and compassionate love levels, and differences occur in parental attitudes, self-compassion and compassionate love levels according to various variables. The research was conducted with 326 university students studying in different departments of Sakarya University Faculty of Education. Parental Attitude Scale (PAS), Self-Compassion Scale (SCS), the Compassionate Love Scale (CLS) and Information Collection Form were applied in the study. The research data were analyzed by correlation, T-test and One Way (ANOVA). The results of the research revealed that the self-compassion level of the students who perceived the parents' attitudes as democratic was high, whereas the self-compassion level of the students who perceived the parental attitudes as authoritarian and protective-demanding was low. It was also found out that the students who perceived their parents' attitudes as authoritarian and protective-demanding had high compassionate love levels. The present study demonstrated the authoritarian and protective-demanding parental attitudes perceived by university students differed according to sex, the democratic parental attitude differed in terms of the number of siblings, and the compassionate love differed in terms of gender. It was revealed that there was a negative relationship between self-compassion and compassionate love.
Magnetohydrodynamics,
Natural Convection, and Entropy Generation of CuO–Water Nanofluid in an I-Shape Enclosure—A
Numerical Study

Published: September 2018

Abstract
This paper presents a numerical study of the magnetohydrodynamics, natural convection, and thermodynamic irreversibilities in an I-shape enclosure, filled with CuO-water nanofluid and subject to a uniform magnetic field. The lateral walls of the enclosure are maintained at different but constant temperatures, while the top and bottom surfaces are adiabatic. The Brownian motion of the nanoparticles is taken into account and an extensive parametric study is conducted. This involves the variation of Rayleigh and Hartmann numbers, and the concentration of nanoparticles and also the geometrical specifications of the enclosure. Further, the behaviors of streamlines and isotherms under varying parameters are visualized. Unlike that in other configurations, the rate of heat transfer in the I-shaped enclosure appears to be highly location dependent and convection from particular surfaces dominates the heat transfer process. It is shown that interactions between the magnetic field and natural convection currents in the investigated enclosure can lead to some peculiarities in the thermal behavior of the system. The results also demonstrate that different parts of the enclosure may feature significantly different levels of heat transfer sensitivity to the applied magnetic field. Further, the analysis of entropy generation indicates that the irreversibility of the system is a strong function of the geometrical parameters and that the variations in these parameters can minimize the total generation of entropy. This study clearly shows that ignoring the exact shape of the enclosure may result in major errors in the prediction of heat transfer and second law performances of the system.

Purpose: To evaluate energy expenditure, energy intake, and nutrient adequacy of Indian junior soccer players. Method: Forty junior national-level soccer players (Under-12 and Under-16 age groups) were assessed for 3-day weighed food records and 3-day energy expenditure. Energy and nutrient intake was analyzed from food records, and energy expenditure was measured using a portable metabolic analyzer and activity records. Nutrient adequacy was determined by comparing intake with prevailing recommendations. Results: Players exhibited no significant difference between energy intake (boys = 3062 [340.9] and girls = 2243 [320.3] kcal·d−1) and expenditure (boys = 2875 [717.3] and girls = 2442 [350.3] kcal·d−1). Across age groups, the Under-12 boys showed positive energy balance as against energy deficits in Under-16. Girls showed energy deficits, although not significant. There were 58% of girls showing energy availability <30 kcal·kg−1 fat-free mass, of which 37% were Under-16 players. Carbohydrates contributed to >60% of energy expenditure among 95.2% boys and 73.7% girls. Among 52.4% boys and 47.4% girls, <25% of energy expenditure was contributed by fat. More than 95% players consumed <1 g·kg−1 carbohydrates pretraining and 100% of them consumed >1.2 g·kg−1 carbohydrates posttraining. Conclusion: Junior soccer players consumed more than recommended carbohydrates in the diet, although not aligning with the pretraining, during training, and posttraining meal requirements. Considering the energy deficits observed among Under-16 players, a suitable dietary modification is warranted.

Published: September 2018

Purpose: Many children attend family child care homes (FCCHs), an important setting to influence children’s physical activity (PA) and sedentary behavior (SB). This study assessed children’s PA and SB while in FCCHs, characteristics of the FCCH PA environment, and relationships between the environment and child PA and SB. Method: Children ages 1.5–4.0 years (n = 495) were recruited from 165 FCCHs in North Carolina. Children’s moderate to vigorous PA and SB were measured via accelerometry for 3 days. FCCH PA environments were assessed over 2 days using the Environment and Policy Assessment and Observation for FCCHs. Ten subscores and an overall PA environment score (possible range: 0–30) were calculated; higher scores indicate better quality. Results: Children accumulated 30 (13) minutes of moderate to vigorous PA and 143 (42) minutes of SB in FCCHs daily. FCCHs scored low on the Environment and Policy Assessment and Observation for FCCHs, with an average overall score of 13 (2). FCCHs scored highest on screen time and screen time practices subscores, and lowest on PA education/professional development and PA policy subscores. Although no statistically significant associations were observed, some large Cohen d effect sizes were noted (eg, outdoor playtime subscore and moderate to vigorous PA). Conclusions: This study highlights opportunities to improve FCCHs and increase children’s behaviors (eg, providing adequate time and outdoor play spaces).

ObjectivesFor very preterm births, to compare alternative policies for umbilical cord clamping and immediate neonatal care.DesignParallel group randomised (1:1) trial, using sealed opaque numbered envelopes.SettingEight UK tertiary maternity units.Participants261 women expected to have a live birth before 32 weeks, and their 276 babies.InterventionsCord clamping after at least 2 min and immediate neonatal care with cord intact, or clamping within 20 s and immediate neonatal care after clamping.Main outcome measuresIntraventricular haemorrhage (IVH), death before discharge.Results132 women (137 babies) were allocated clamping ≥2 min and neonatal care cord intact, and 129 (139) clamping ≤20 s and neonatal care after clamping; six mother-infant dyads were excluded (2, 4) as birth was after 35+6 weeks, one withdrew (death data only available) (0, 1). Median gestation was 28.9 weeks for those allocated clamping ≥2 min, and 29.2 for those allocated clamping ≤20 s. Median time to clamping was 120 and 11 s, respectively. 7 of 135 infants (5.2%) allocated clamping ≥2 min died and 15 of 135 (11.1%) allocated clamping ≤20 s; risk difference (RD) −5.9% (95% CI −12.4% to 0.6%). Of live births, 43 of 134 (32%) had IVH vs 47 of 132 (36%), respectively; RD −3.5% (−14.9% to 7.8%). There were no clear differences in other outcomes for infants or mothers.ConclusionsThis is promising evidence that clamping after at least 2 min and immediate neonatal care with cord intact at very preterm birth may improve outcome; a large trial is urgently needed.Trial registrationISRCTN 21456601.

ObjectiveTo determine whether prenatal and perinatal maternal consumption of alcohol, tobacco and/or illicit drugs is associated with risk of neuroblastoma.Data sourcesMedline and Embase (both from inception to February 2017), and reference lists of included studies.Study selectionTo be eligible, a study had to be an original report including data on intake of alcohol, tobacco smoking and/or consumption of illicit drugs during pregnancy and risk of neuroblastoma in the child.Data extractionFrom eligible studies, data study characteristics as well as effect measures and confounders were extracted. We assessed unadjusted and confounder-adjusted estimates, performed risk of bias analysis, constructed random-effects models and assessed heterogeneity.ResultsWe identified 14 case–control studies (1987–2016) involving a total of 3114 children with neuroblastoma. Meta-analysis of unadjusted estimates showed an association between alcohol (OR 1.26; 95% CI 1.07 to 1.49), tobacco (OR 1.22; 95% CI 1.04 to 1.44) and illicit drug consumption during pregnancy and risk of neuroblastoma during childhood, with illicit drug consumption showing the strongest association (OR 3.26; 95% CI 1.36 to 7.86). However, adjusted estimates were highly heterogeneous.LimitationsAll studies were at high risk of bias.ConclusionsSmoking, alcohol or illicit drugs during pregnancy might play a role in the development of neuroblastoma. However, well-designed studies are needed to assess whether these exposures are causal and whether time period during pregnancy, dose or co-consumption of substances is critical.Trial registration numberRegistration number CRD42016036165.

BackgroundTo assess prevalence and causes of vision impairment in South-east Asia and Oceania regions from 1990 to 2015 and to forecast the figures for 2020.MethodsBased on a systematic review of medical literature, prevalence of blindness (presenting visual acuity (PVA) <3/60 in the better eye), moderate and severe vision impairment (MSVI; PVA <6/18 but ≥3/60), mild vision impairment (PVA <6/12 but ≥6/18) and near vision impairment (>N5 or N8 in the presence of normal vision) were estimated for 1990, 2010, 2015 and 2020.ResultsThe age-standardised prevalence of blindness for all ages and both genders was higher in the Oceania region but lower for MSVI when comparing the subregions. The prevalence of near vision impairment in people≥50 years was 41% (uncertainty interval (UI) 18.8 to 65.9). Comparison of the data for 2015 with 2020 predicts a small increase in the numbers of people affected by blindness, MSVI and mild VI in both subregions. The numbers predicted for near VI in South-east Asia are from 90.68 million in 2015 to 102.88 million in 2020. The main causes of blindness and MSVI in both subregions in 2015 were cataract, uncorrected refractive error, glaucoma, corneal disease and age-related macular degeneration. There was no trachoma in Oceania from 1990 and decreasing prevalence in South-east Asia with elimination predicted by 2020.ConclusionsIn both regions, the main challenges for eye care come from cataract which remains the main cause of blindness with uncorrected refractive error the main cause of MSVI. The trend between 1990 and 2015 is for a lower prevalence of blindness and MSVI in both regions.

AbstractObjectiveTo perform an expedited assessment of cancer risk associated with exposure to N-nitrosodimethylamine (NDMA) through contaminated valsartan products.DesignNationwide cohort study.SettingDanish health registries on individual level prescription drug use, cancer occurrence, and hospital diagnoses.Participants5150 Danish patients with no history of cancer, aged 40 years or older, and using valsartan at 1 January 2012 or initiating use between 1 January 2012 and 30 June 2017. Participants were followed from one year after cohort entry (lag time period) until experiencing a cancer outcome, death, migration, or end of study period (30 June 2018). Each participant’s exposure to NDMA (ever exposure and predefined categories of cumulative valsartan exposure) was mapped out as a time varying variable while also applying a one year lag.Main outcome measuresAssociation between NDMA exposure and a primary composite endpoint comprising all cancers except non-melanoma skin cancer, estimated using Cox regression. In supplementary analyses, the risk of individual cancers was determined.ResultsThe final cohort comprised 5150 people followed for a median of 4.6 years. In total, 3625 cohort participants contributed 7344 person years classified as unexposed to NDMA, and 3450 participants contributed 11 920 person years classified as ever exposed to NDMA. With 104 cancer outcomes among NDMA unexposed participants and 198 among exposed participants, the adjusted hazard ratio for overall cancer was 1.09 (95% confidence interval 0.85 to 1.41), with no evidence of a dose-response relation (P=0.70). For single cancer outcomes, increases in risk were observed for colorectal cancer (hazard ratio 1.46, 95% confidence interval 0.79 to 2.73) and for uterine cancer (1.81, 0.55 to 5.90), although with wide confidence intervals that included the null.ConclusionsThe results do not imply a markedly increased short term overall risk of cancer in users of valsartan contaminated with NDMA. However, uncertainty persists about single cancer outcomes, and studies with longer follow-up are needed to assess long term cancer risk.
