Highly-Skilled Labour Migration in Switzerland: Household Strategies and Professional Careers

The article investigates household strategies in the context of highly-skilled labour migration. It focuses on the ways highly-skilled migrants are taking up residence in Switzerland. The analysis shows different household strategies based on the perception of a further professional move. The perceived likeliness of a further move implies household strategies characterized by a high motility: the household remains ready to move and mobilises dedicated organisations (like outplacement agencies or international schools). When a further move is neither perceived nor wanted, the household develops more anchored strategies which are often cheaper. In order to cope with frequent mobilities, the analysis shows that household strategies are deeply gendered.
Diffusion, Optimal Transport and Ricci Curvature for Metric Measure Space

Lower Ricci curvature bounds play a crucial role in several deep geometric and functional inequalities in Riemannian geometry and diffusion processes. Bakry–Émery [8] introduced an elegant and powerful technique, based on commutator estimates for differential operators and so-called Γ-calculus, to derive many sharp results. Their curvature-dimension condition has been further developed by many authors, mainly in the framework of Markov diffusion modelled on weighted Riemannian manifolds, with relevant applications to infinite dimensional problems. A new synthetic approach relying on entropy and optimal transport has been more recently introduced by Lott, Sturm and Villani. It relies structurally on the notions of distance and measure and can therefore be used to extend the curvature-dimension condition to the general nonsmooth setting of metric measure spaces (X, d,m). Among its many beautiful properties, the synthetic approach is stable with respect to measured Gromov convergence. The equivalence of the two points of view can be directly proved in a smooth differential setting but it is a difficult task in a general metric framework, when explicit calculations in local charts are hard (if not impossible) to justify. We will try to give a brief and informal introduction to the two approaches and show how the Otto variational interpretation of the Fokker-Planck equation and the theory of metric gradient flows has provided a unifying point of view, which allows one to prove their equivalence for arbitrary metric measure spaces. As a byproduct, by combining Γ-calculus and optimal transport techniques, an impressive list of deep results in Riemannian geometry and smooth diffusion have a natural counterpart in the nonsmooth metric measure framework.
Trace elements and radioactivity measurements in some terrestrial food crops in Jos-plateau, north central, Nigeria

Some crops of important nutritive requirements have been collected from farmlands located in Bitsichi an old tin mining town in north central region of Nigeria. The food crops were analyzed in order to determine trace element concentrations level using Neutron Activation Analysis (NAA). The activity concentrations due to natural radionuclides in the food samples and soil samples collected within the root zone of the crops were also determined using gamma-ray spectrometry (GRS). The NAA results obtained showed higher concentration of Potassium among the essential elements in all the crops. Calcium concentration in both maize and Guinea corn was below detection limit and also Zn in Green beans, sweet potato and cassava. The trace elements; Sc, Hf, Sm, and Th, were below detection limit in all the crops except in Green beans. Rubidium (Rb) and lanthanum (La) were below detection limits only in Cabbage. The activity concentrations of the natural radionuclides in the food samples were found to vary between 83 and 129 Bq kg -1 for 40 K, 19 and 30 Bq kg -1 for 226 Ra and 27 to 41 Bq kg -1 for 232 Th. In the soil samples the activity concentrations varied between 177 and 271 Bq kg -1 for 40 K, 53 and 96 Bq kg -1 for 226 Ra and 73 to 176 Bq kg -1 for 232 Th. Results of activity concentration levels of the radionuclides obtained in similar crops collected for control measurements were found to be very low compared to those from the study area. The effective dose due to intake of the food crops considered in the study area was estimated based on the measured activity concentrations of 226 Ra and 232 Th in the food crops. It was found to vary between 0.01 mSv y -1 (Acha) and 1.35 mSv y -1 (Cassava) with a cumulative total dose estimated as 2.5 mSv y -1 . The mining activities in the area are seen to have influenced the concentration of these trace elements and radionuclides in the food crops. However, they are seen not to pose any serious internal health burden due to ingestion given the realities of food choice by individuals in the study area.
Efflux Time from Tanks with Exit Pipes and Fittings

The efflux time experiment is simple to construct, simple to operate, and very useful for teaching the fundamentals of fluid flow, friction loss, and data analysis in an engineering laboratory course that addresses fluid mechanics. Students have the opportunity to study the effect of various critical parameters and dimensions on the time to drain a tank, analyze the data, and draw meaningful conclusions.
Geothermal measurements from drilling of sediments near the Galapagos spreading center, 86oW, Deep Sea Drilling Project Leg 70.

Heat transfer processes at the mounds area of the Galapagos Spreading Center at 86 °W are revealed by temperatures measured at 10-meter intervals in the 30 ± 10 meter sediment at each of 12 holes at Leg 70, Sites 506-509. Two hundred fourteen needle-probe values show a significant linear increase of thermal conductivity with depth in each hole. About half of the temperature-thermal resistance profiles are nonlinear and are fit to a steady-state, vertical porewater convection model. Results indicate high and variable total heat flow and localized hydrothermal discharge at < 10~ m/s, associated with individual mounds. Recharge at similar rates is indicated in the low heat-flow belt 5 km south of the mounds. Possible slow entrained recharge within 100 meters of discharging mounds is suggested. At Site 510, temperatures in the 114-meter sediment cover on 2.7 million-year old crust are linear, suggesting that the hydraulic resistance of this layer is sufficient to seal off free hydrothermal exchange between basement and bottom water. The combination of heat-flow data and physical-properties data of Karato and Becker (this volume) suggests that 50 meters of sediment may be a threshold thickness for sealing of hydrothermal circulation within basement, where the topography is smooth. We suggest that the formation of mounds may be associated with the forced localization of hydrothermal discharge through the sediment, as its thickness approaches this threshold value.
One-way and quasi-periodic climate changes: Geologic evidence

During the last three billion years, the Earth has been experiencing a slow global cooling, expressed in the progressively increasing frequency and scale of glacial events. Based on these indications, geologic history can be divided into three climatic stages: (a) non- glacial (Early and Middle Archean), (b) with episodic glaciations (Late Archean to Middle Riphean), and (c) with frequent periodic glaciations (Late Riphean-present). The cooling has apparently been caused by changes in the density and composition of the atmosphere, by the waning of heat flow from the Earth's interior, and by an increase in the planet's albedo in response to continental growth. The irreversible climate trend was modulated and obscured by numerous superposed temperature oscillations of varying periodicity and amplitude. A broad spectrum of such oscillations, from ultralong-term (a few hundreds of million years) to decadal-scale, have been established. The Phanerozoic exhibits a hierarchy of coordinated periods of climatic oscillations of 10-12 ranks. Climatic oscillations of the first two or three ranks are to be detected in Proterozoic glacial sequences. In light of the above, the Earth's climate history appears to be naturally determined, the slow irreversible cooling of the Earth's surface being superposed by a rather regular pattern of periodic oscillations. The inference suggests itself that the Earth's highly complex and open climate system has been rather close to a stationary state, and that among the multitude of nonlinear processes bearing on climate there were a small number of those most influential, "governing" processes with periodic attractors. Glaciation maxima preceded principal tectonic phases, and they are clearly correlative to suprasubduction volcanic maxima, whereas the periods of degradation or cessation of glaciation coincide with tectonic, granitization, metamorphic, and, occasionally, mantle-plume volcanic maxima. This suggests that onsets of glaciation were triggered by explosive volcanism and by the ensuing volcanic winters. Deglaciations must have been due to increases in atmospheric transparency, to carbon oxidation and partial decarbonatization in sedimentary sequences of orogens, and to pulses of mantle plume volcanism. A similar explanation applies to long-term climatic oscillations that lasted 30 m.y. on average. Short-term climatic oscillations are explicable by variations in the astronomical parameters of our planet, and ultrashort-term ones, apparently, by solar activity variations.
Pruning effect in Eucalyptus grandis x Eucalyptus urophylla clone growth

The objective of this paper is to determine the pruning level that does not affect tree growth, increasing the amount of clear wood production in a single lift at age 1.3 years. The experiment was developed in the municipality of Aracruz, Espírito Santo state, Brazil. The pruning intensities considered were: 40%, 55%, 70% and 85% of the total tree height, as well as no pruning for control. The results obtained three years after pruning showed that it is possible to reach up to a 70% of total tree height pruned (mean pruned height of 7.3 m) in a single pruning lift without affecting the size of the 700 largest trees per hectare in diameter. High intensity pruning (85%) translated into negative effects on tree growth. Low intensity pruning (40%) also had moderate effects on growth, possibly due to exposure of negative effects of leaf area removal without benefiting from the positive effects on canopy characteristics. Finally, the paper discusses different thinning regimes and its implications on the pruning regime. The results of this research can contribute to improve the management of fast growing plantations for timber production.

Cortical Alpha Oscillation During 3 kHz Steady-State Sinusoidal Electric Current Stimulation

Little is known about the changes in ongoing cortical rhythms due to application of the steady-state sinusoidal electrical stimuli of 3 kHz, although it has been shown to elicit tactile sensations. In addition, it is known that somatosensory stimulation attenuates ongoing alpha rhythm in centroparietal cortex. Thus, the present work aimed to evaluate alpha rhythm alterations in sensorimotor area and sensations perceived with application of 3 kHz sinusoidal stimulus. Sensory perception threshold (ST) was measured in ten healthy volunteers for posterior stimulation in three distinct stimulus intensities (1.1xST, 2xST and 3xST). Cognitive evaluation of perceived sensations was obtained through questionnaires and cortical alpha rhythm blockade profile was evaluated through the classical event-related synchronization/ desynchronization method. Results showed alpha attenuation in the central cortex bilaterally, in the ipsilateral pre-frontal cortex and contralateral parietal cortex during stimulation. Moreover, there was a tendency of bilateral centroparietal alpha rhythm desynchronization increase with stimulus intensity. In conclusion, sinusoidal electrical stimulation may be useful for disease diagnostics and treatment as well as neurofeedback for brain-machine interface (BMI) applications. Patients may benefit from the novel objective method proposed for assessment of tactile perception, mainly, who might not have their cognition preserved (e.g., stroke).
Antibiotics in Aquaculture – Use, Abuse and Alternatives

According to the UN Food and Agriculture Organization, aquaculture is growing more rapidly than all other animal food-production sectors (www.fao.org). Its contribution to global supplies of several species of fish, crustaceans and mollusks increased from 3.9% of total production by weight in 1970 to 33% in 2005. It has been estimated that fisheries and aquaculture supplied the world with about 110 million metric tons of food fish per year (FAO, State of World Fisheries and Aquaculture 2010.), providing a per capita supply of 16.7 kg (live weight equivalent). Of this supply, 47% is derived from aquaculture production. However, this production is hampered by unpredictable mortalities that may be due to negative interactions between fish and pathogenic bacteria. To solve this problem, farmers frequently use antibiotic compounds to treat bacterial diseases (Cabello 2006).
Impact on quality culture of total quality management practices factors

This study investigated total quality management practices and quality culture of Saudi Arabian contractors. Improving the quality can be achieved through implementation of total quality management although studies and researches work regarding this improvement is still lacking. A quantitative approach using the survey method was employed. With assistance from the Saudi Arabia Ministry of Municipal and Rural Affairs, survey questionnaires were distributed to selected contractors in Saudi Arabia. The collected data were analysed using correlation, and multiple regression analyses. The key findings were the confirmation of significant relationships between all total quality management practices and quality culture and a positive relationship between quality management practices and quality culture. Furthermore, total quality management practices were found to be able to explain 68.1% of the variance in quality culture, while quality culture explained 12.5% of the variance in competitiveness. Quality culture was found to only partially mediate the relationship between total quality management practices and competitiveness.
English Language Learners in Canadian Schools: Emerging Directions for School-Based Policies.

This article attempts to provide ESL teachers, school administrators, and policymakers with a concise overview of what matters in promoting academic success among learners of English in Canadian schools. We review research focused on bilingual and biliteracy development, the nature of academic language, and the roles of societal power relations and identity negotiation in determining the academic achievement of English language learners (ELL). On the basis of this research, we propose the Literacy Engagement framework that identifies literacy engagement as a major determinant of literacy achievement for ELL and non-ELL students. In order to enable ELL students to engage with literacy, the framework highlights the importance of teachers scaffolding meaning, connecting with students’ lives, affirming student identities, and extending their awareness and knowledge of language across the curriculum. The application of the framework is illustrated with reference to the literacy and academic learning experiences of two ELL students in the Toronto area.
Comparative Study of Phenolic Content and Antioxidant Activity of Leaf Extracts of Alstonia boonei and Eupatorium odoratum

This study investigated the in vitro antioxidant activity and phenolic content of aqueous and ethanol extracts of Alstonia boonei and Eupatorium odoratum leaves . Total phenol, flavonoid and flavonol content of the extracts were estimated to determine the levels of phenolics in the extracts. The antioxidant capacity of the extracts were assessed through diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging activity, ferric reducing antioxidant power (FRAP) and reducing power (RP). The results revealed that the DPPH radical scavenging ability of aqueous extract of E. odoratum (with IC 50 = 0.07± 0.003mg/ml) compares favourably with that of the standard ascorbic acid (IC 50 = 0.06 ± 0.01 mg/ml). There was a dose-dependent increase in FRAP and RP capacity in all the extracts. The ethanol extract of E. odoratum had the highest FRAP while the aqueous extract of A. boonei showed the highest RP ability when compared with the other extracts. However, flavonol content was highest in the aqueous extract of E. odoratum followed by ethanol extract of A. boonei . The phenolic and flavonoid contents of extracts of E. odoratum were higher than that of A. boonei extracts. This study, therefore, reveals that aqueous extract of A. boonei and ethanol extract of E. odoratum leaf are more effective free radical scavengers and antioxidants relative to the other extract forms. These findings support the use of these extracts as potential sources of natural antioxidants. Keywords: Alstonia boonei, Eupatorium odoratum, phenolics, antioxidant
AN ASSESSMENT OF THE PRESENCE OF LISTERIA MONOCYTOGENES IN READY-TO-EAT FOOD AND FRUITS SOLD IN MARKETS IN GUINEA SAVANNA BELT-NIGERIA

The pathogenic nature of Listeriamoncytogenes, and its ability to grow even at refrigerated temperature makes the bacterium a significant threat to the safety of ready to eat and other food products. Therefore, a comparative study of Listeriamonocytogenes in ready to eat food and fruits sold in Gboko markets was carried out to determine the prevalence of the bacterium in the food products. A total of 1080 samples of these food products were collected randomly from the Gboko markets and analysed. Out of thisusing Predictive Arithmetic Software (PASW) total number of samples analysed, 28(2.59%) contained Listeriamonocytogenes which were all from ready to eat food products (‘Deli’ salad and ‘Suya’ meat). Meat pie and fruits were known to have no isolates (pathogen). The non incidence of this pathogen in meat pie could due to the dry heat condition applied during preparation and processing of the food.
The effect of self-efficacy on the lifelong learning tendencies of Computer Education and Instructional Technologies pre- service teachers: A case study

The main purpose of this study was to investigate the effect of self-efficacy on the lifelong learning tendencies of Computer Education and Instructional Technologies (CEIT) pre-service teachers. The second aim was to determine the level of lifelong learning tendencies of those pre-service teachers and to investigate how it differs with respect to some variables. Data were collected from the pre-service teachers of Computer Education and Instructional Technologies (CEIT) department of a large foundation university located in Istanbul, Turkey. CEIT students’ lifelong learning tendency was assessed by Coskun Diker and Demirel’s (2010) 27-item Lifelong Learning Tendency Scale. Students’ self-efficacy was measured by a 17-item scale which was originally developed and validated by Sherer and Adams (1983) and translated into Turkish by Yildirim and Ilhan (2010). The data was analyzed using IBM SPPS Statistics 19. The results of this study may give guidance to administrators, faculty members and consultants who wish to empower students to manage their own learning and help them develop more positive attitudes towards lifelong learning.
Development of rail infrastructure and its impact on urbanization in the Randstad, the Netherlands

Long-term, large-scale empirical studies on the simultaneous development of transport infrastructure and the built environment are scarce. This paper provides a long-term study of the development of the railway network and its impact on the built-up area—and vice versa—using the case study of the Randstad in the Netherlands between 1850 and 2010. The analysis is both qualitative and quantitative. We describe the shares of the built-up area in concentric buffers of 1-kilometer intervals from railway stations and estimate binomial logit models to predict the likelihood of new stations being built based on the amount of the preceding and subsequent built-up area and the likelihood that a new station might have encouraged further growth. Results show that during the early days stations followed existing urbanization patterns. But as time went by, new stations were more likely to be located in undeveloped areas and less likely to be located within the established built-up areas, which were already serviced by existing stations. Moreover, they prompted further growth, increasing the likelihood of more urbanization in their vicinity.
Dysfunctional uterine bleeding: ormeloxifene versus combined oral contraceptive pills

Background: Dysfunctional uterine bleeding is abnormal bleeding that occurs in the absence of recognizable pelvic pathology, general medical disease, or pregnancy. Globally, health care systems are focusing on low morbidity and low cost therapeutic interventions. Hence, medical treatment for DUB is high on the priority list. This comparative study was conducted to analyse the efficacy of ormeloxifene and combined oral contraceptive pills in reducing the blood loss and endometrial thickness in cases of DUB.Methods: This prospective study was conducted on women with dysfunctional uterine bleeding, who attended Gynaecology OPD at Hind Institute of Medical Sciences, between August 2015 and April 2016. After applying inclusion and exclusion criteria, 72 women diagnosed with DUB were enrolled randomly in two groups A and B. Group A was treated by Ormeloxifene and Group B patients were treated with combined oral contraceptive pills for three consecutive cycles. The efficacies of the studied drugs were compared by analyzing the mean change in the pre and post treatment PBAC score, haemoglobin level and endometrial thickness using unpaired t-test.Results: Ormeloxifene was found to be significantly more effective (p <0.0001) than OCPs in controlling the menstrual blood loss (79% reduction in group A Vs 55.5% reduction in group B). Reduction in endometrial thickness was also more in the group receiving Ormrloxifene, however this was statistically not significant (p = 0.19). No major side effect observed with the use of Ormeloxifene.Conclusions: Ormeloxifene can be an effective and safe therapy in the treatment of Dysfunctional uterine bleeding.
