Lifestyles of higher education students: the influence of self- esteem and psychological well-being

Background The transition to higher education can affect lifestyle-related factors. Objectives: To identify lifestyles of higher education students and analyse the influence of self-esteem and psychological well-being. Methods Correlational cross-sectional study. A total of 4,314 students partici- pated in the study. Online questionnaires were used: Estilo de Vida Fantástico (Fantastic Lifestyle Assessment) [1]; Questionário de Bem- estar Psicológico (Psychological General Well-Being Questionnaire) [2], and Escala de auto-estima de Rosenberg (Rosenberg Self-Esteem Scale [3]. Results Most students (85.3 %) have a healthy lifestyle. Lifestyle is strongly correlated with self-esteem and psychological well-being (p < 0.001). While analysing the association between self-esteem and psycho- logical well-being and the various lifestyle domains according to gen- der, a positive and significant correlation (p < 0.001) was found among female students, except for the Smoking domain (p = 0.393); in relation to psychological well-being, positive correlations were found in all domains. Among male students, positive and significant correlations (p < 0.001) were found in most lifestyle domains and self-esteem, except for the Smoking (p = 0.992), Alcohol and other drugs (p = 0.181) and Other behaviours (p = 0.442) domains; in rela- tion to psychological well-being, positive and significant correlations (p < 0.001) were found in most lifestyle domains, except for the Smoking (p = 0.458) and Other behaviours (p = 0.128) domains. Conclusions Based on the results, higher education institutions should support intervention projects to maintain high levels of psychological well- being and self-esteem, promoting healthy lifestyles.

Multi-Scale Dynamic Study of Secondary Impact During Drop Testing of Surface Mount Packages

This dissertation focuses on design challenges caused by secondary impacts to printed wiring assemblies (PWAs) within hand-held electronics due to accidental drop or impact loading. The continuing increase of functionality, miniaturization and affordability has resulted in a decrease in the size and weight of handheld electronic products. As a result, PWAs have become thinner and the clearances between surrounding structures have decreased. The resulting increase in flexibility of the PWAs in combination with the reduced clearances requires new design rules to minimize and survive possible internal collisions impacts between PWAs and surrounding structures. Such collisions are being termed ‘secondary impact’ in this study. The effect of secondary impact on board-level drop reliability of printed wiring boards (PWBs) assembled with MEMS microphone components, is investigated using a combination of testing, response and stress analysis, and damage modeling. The response analysis is conducted using a combination of numerical finite element modeling and simplified analytic models for additional parametric sensitivity studies.

Biological activities (antibacterial, antifungal and cytotoxic) of secondary metabolites of Ircinia spp.

Sponges are the most primitive of the multicellular, These organisms don’t have any mechanical defense system, so their early appearance in evolution has given them a lot of time for the development of advanced secondary metabolites as chemical defense system. Sponges have the potential to provide drugs from chemical components against diseases. In this investigation the sponge samples, which it is Ircina spp., were collected at depth of 15- 24 meter, from locations on the coastline of Island Kish in Persian Gulf of Iran. For identifying natural components, methanolic and diethyletter were used as extraction solvents, after removal of the solvents, the GC/MS spectra of the fraction were obtained. Then in vitro cytotoxic, antimicrobial and antifungal were identified. In vitro cytotoxity screening, by XTT assay, against KB/ C359 and HUT-56/ C365 cell line, was conducted in this study in 1 - 544 μg/ml. IC54 for winter diethyletter extract was 325 μg/ml, winter methanolic extract was 364 μg/ml, IC54 for summer diethyletter extract was 544 μg/ml, and summer methanolic extract was 454 μg/ml in HUT-56. IC54 for winter diethyletter extract was 454 μg/ml, winter methanolic extract was 444 μg/ml, IC54 for summer diethyletter extract was 344 μg/ml, and summer methanolic extract was 424 μg/ml in KB.

The results conducted that the MIC values of winter diethyletter extract for Escherichia coli 24mg/ml, the MIC values of winter diethyletter extract for Escherichia coli 24mg/ml, the MIC and MBC values of winter diethyletter extract for Staphylococcus aureus was 2mg/ml and 24mg/ml. The MIC and MBC values of winter diethyletter extract for Bacillus subtilis was 1.5 mg/ml and 2mg/ml. In vitro antifungal activity by Broth Dilution Methods against clinical pathogens; Candida albicans and Aspergillus fumigatus. The results conducted that the aqueous extracts didn’t have any antifungal activities on pathogens, the MFC of the summer and winter diethyletter extract was 30 mg/ml and 2 mg/ml A. fumigates, the summer and winter methanolic extract was 0722 mg/ml and 2 mg/ml A. fumigates, the summer and winter methanolic was 4/75mg/ml, MFC 5 mg/ml on C. albicans.

Effective Approaches to Enhancing the Social Dimension of Higher Education

Despite all intentions in the course of the Bologna Process and decades of investment into improving the social dimension, results in many national and international studies show that inequity remains stubbornly persistent, and that inequity based on socio-economic status, parental education, gender, country-of-origin, rural background and more continues to prevail in our Higher Education systems and at the labour market. While improvement has been shown, extrapolation of the gains of the last 40 years in the field show that it could take over 100 years for disadvantaged groups to catch up with their more advantaged peers, should the current rate of improvement be maintained. Many of the traditional approaches to improving equity have also necessitated large-scale public investments, in the form of direct support to underrepresented groups. In an age of austerity, many countries in Europe are finding it necessary to revisit and scale down these policies, so as to accommodate other priorities, such as balanced budgets or dealing with an aging population. An analysis of the current situation indicates that the time is ripe for disruptive innovations to mobilise the cause forward by leaps and bounds, instead of through incrementalist approaches. Despite the list of programmes in this analysis there is very little evidence as to the causal link between programmes, methodologies for their use and increases/improvements in equity in institutions. This creates a significant information gap for institutions and public authorities seeking for indicators to allocate limited resources to equity improving initiatives, without adequate evidence of effectiveness. The IDEAS project and this publication aims at addressing and improving this information gap. (DIPF/Orig.)

Ray-theoretical modeling of secondary microseism P-waves

Secondary microseism sources are pressure fluctuations close to the ocean surface. They generate acoustic P-waves that propagate in water down to the ocean bottom where they are partly reflected, and partly transmitted into the crust to continue their propagation through the Earth. We present the theory for computing the displacement power spectral density of secondary microseism P-waves recorded by receivers in the far field. In the frequency domain, the P-wave displacement can be modeled as the product of (1) the pressure source, (2) the source site effect that accounts for the constructive interference of multiply reflected P-waves in the ocean, (3) the propagation from the ocean bottom to the stations, (4) the receiver site effect. Secondary microseism P-waves have weak amplitudes, but they can be investigated by beamforming analysis. We validate our approach by analyzing the seismic signals generated by Typhoon Ioke (2006) and recorded by the Southern California Seismic Network. Back projecting the beam onto the ocean surface enables to follow the source motion. The observed beam centroid is in the vicinity of the pressure source derived from the ocean wave model WAVEWATCH IIIR. The pressure source is then used for modeling the beam and a good agreement is obtained between measured and modeled beam amplitude variation over time. This modeling approach can be used to invert P-wave noise data and retrieve the source intensity and lateral extent.

Scenarios of mentor education in Romania - towards improving teacher induction

The aim of this paper is to examine the induction programme for newly qualified teachers and mentor education in Estonia, providing a comparative analysis of existing Estonian and possible Romanian models of mentoring. While the Estonian induction programme has been in place for more than ten years, induction in Romania is a relatively new and has only been mandatory since 2011 (National Law of Education 1/2011). The specifics of mentor professional development within the Romanian induction framework have yet to be explicated. This paper proposes two possible scenarios suitable for the Romanian system :1) long-term regulated academic education (part of master or doctoral level studies), and 2) flexible short-term in-service education. The advantages and disadvantages of both models are examined and ways to overcome some of the disadvantages are identified. Ultimately, the paper proposes that a flexible, needsdriven system which encompasses a degree of choice will best fulfil the professional development needs of teachers who wish to become mentors.

When theories become practice - a metaphorical analysis of adult-education school-leaders’ talk

Marketization has changed the education system. If we say that education is a market, this transforms the understanding of education and influences how people act. In this paper, adult-education school-leaders’ talk is analysed and seven metaphors for education are found: education as administration, market, matching, democracy, policy work, integration and learning. Exploring empirical metaphors provides a rich illustration of coinciding meanings. In line with studies on policy texts, economic metaphors are found to dominate. This should be understood not only as representing liberal ideology, as is often discussed in analyses of policy papers, but also as representing economic theory. In other words, contemporary adult education can be understood as driven by economic theories. The difference and relation between ideology and theory should be further examined since they have an impact on our society and on our everyday lives. (DIPF/Orig.)

Modeling the Effect of Vapor Wall Deposition on the Formation of Secondary Organic Aerosol in Chamber Studies

Laboratory chamber experiments are used to investigate formation of secondary organic aerosol (SOA) from biogenic and anthropogenic precursors under a variety of environmental conditions. Simulations of these experiments test our understanding of the prevailing chemistry of SOA formation as well as the dynamic processes occurring in the chamber itself. One dynamic process occurring in the chamber that was only recently recognized is the deposition of vapor species to the Teflon walls of the chamber. Low-volatility products formed from the oxidation of volatile organic compounds (VOCs) deposit on the walls rather than forming SOA, decreasing the amount of SOA formed (quantified as the SOA yield: mass of SOA formed per mass of VOC reacted). In this work, several modeling studies are presented that address the effect of vapor wall deposition on SOA formation in chambers.

A coupled vapor-particle dynamics model is used to examine the competition among the rates of gas-phase oxidation to low volatility products, wall deposition of these products, and mass transfer to the particle phase. The relative time scales of these rates control the amount of SOA formed by affecting the influence of vapor wall deposition. Simulations show that an effect on SOA yield of changing the vapor-particle mass transfer rate is only observed when SOA formation is kinetically limited. For systems with kinetically limited SOA formation, increasing the rate of vapor-particle mass transfer by increasing the concentration of seed particles is an effective way to minimize the effect of vapor wall deposition.

This coupled vapor-particle dynamics model is then applied to α-pinene ozonolysis SOA experiments. Experiments show that the SOA yield is affected when changing the oxidation rate but not when changing the rate of gas-particle mass transfer by changing the concentration of seed particles. Model simulations show that the absence of an effect of changing the seed particle concentration is consistent with SOA formation being governed by quasi-equilibrium growth, in which gas-particle equilibrium is established much faster than the rate of change of the gas-phase concentration. The observed effect of oxidation rate on SOA yield arises due to the presence of vapor wall deposition: gas-phase oxidation products are produced more quickly and condense preferentially onto seed particles before being lost to the walls. Therefore, for α-pinene ozonolysis, increasing the oxidation rate is the most effective way to mitigate the influence of vapor wall deposition.

Finally, the detailed model GECKO-A (Generator for Explicit Chemistry and Kinetics of Organics in the Atmosphere) is used to simulate α-pinene photooxidation SOA experiments. Unexpectedly, α-pinene OH oxidation experiments show no effect when changing either the oxidation rate or the vapor-particle mass transfer rate, whereas GECKO-A predicts that changing the oxidation rate should drastically affect the SOA yield. Sensitivity studies show that the assumed magnitude of the vapor wall deposition rate can greatly affect conclusions drawn from comparisons between simulations and experiments. If vapor wall loss in the Caltech chamber is of order 10^-5 s^-1, GECKO-A greatly overpredicts SOA during high UV experiments, likely due to an overprediction of second-generation products. However, if instead vapor wall loss in the Caltech chamber is of order 10^-3 s^-1, GECKO-A greatly underpredicts SOA during low UV experiments, possibly due to missing autoxidation pathways in the α-pinene mechanism.

A New Concept of Interprofessional Education in Planning Programmes: Reflections on Healthy Urban Planning Project

Although widely debated, some of the defining professional characteristics of planners appear to be competencies in coordination , mediation and multidisciplinary working. Despite this, there is little pedagogical reflection on how interprofessional skills are promoted in planning programmes. This paper reflects on the experience of bringing together undergraduate students from medicine and planning to explore the concept of Healthy Urban Planning in a real life context of an urban motorway extension. This reveals a number of unexpected outcomes of such collaboration and points to the value of promoting interprofessional education, both as a way of increasing interest in some of the key challenges now facing society and in order to induce greater professional reflection amongst our students.
