Examining competences in online journalism at Spanish Universities: The case of the Miguel Hernández University
Authors: de Lara Alicia , García-Avilés Jose A. 
Published: November 2013

Abstract
Major changes in the workplace associated with the widespread use of online journalism, the consequences of news gathering in a digital environment and the ability to produce content for multimedia platforms are setting new goals in journalism education. One of the defining features of journalism university education is the requirement that students demonstrate their understanding of core skills by producing professional work. The identification of competencies constitutes one of the key dimensions in current Journalism education. This article examines the Online Journalism courses at the Miguel Hernández University (Spain), in order to analyse the competences acquired by the students. The methodology includes a multi-layered approach: on the one hand, we conducted interviews with over twenty media professionals who currently work in Spanish online media, to identify the skills that are most demanded. Their answers provided a working framework during the design and implementation of our research. We also carried out a survey with 250 students in their final years of the Grade in Journalism at the UMH, with the aim of exploring their adaptation to five specific courses: news writing, media production, online news design, digital communication and database management.
Reflections from the classroom: Teaching the history of journalism in the digital age
Authors: Sánchez Illán Muhammad Idrees 
Published: November 2013

Abstract
This essay argues, provocatively perhaps, that journalism history should be at the core of journalism education in the digital age. In so doing, it proposes a fundamental role for historical awareness in the formative process of journalists and other media professionals that undertake this field of study. In this way, one of the key objectives of a discrete journalism degree can be to ensure a rational and critical knowledge of the present, as well as the assessment and understanding of its basic professional boundaries (political, social, economic and cultural) and how they have been shaped historically. The main purpose of this historical emphasis is to ensure that the next generations of journalists might be able to understand today’s society and make it comprehensible to others. Through this project, it is argued here that students in particular and the academy in general can become aware of the significant synthesis of accumulated knowledge that journalism represents as an organic and quasi-coherent social phenomena.
Physical Activity and Policy Recommendations: A Social Multiplier Approach
Authors: Goulão Catarina , Thibault Emmanuel 
Published: November 2013

Abstract
We look at the effects of physical activity (PA) recommendation policies by considering a social multiplier model in which individuals differ in their concern for PA. The government can either observe this concern (and implement the First Best) or not (and implement a uniform policy). Whichever the type of policy implemented, while the welfare of individuals the most concerned with PA increases in the social multiplier, the welfare of those the least concerned may decrease in it. For a sufficiently high social multiplier, both government interventions improve the welfare of those most concerned with PA but worsen the welfare of the least concerned individuals if they are not too many. However, compared to the First Best, a uniform recommendation improves the welfare of those most concerned with PA more than it reduces the welfare of those least concerned.
Transient diabetes insipidus with severe maternal and fetal hypernatremia
Authors: Ko Jennifer K.Y. , Shek Noel W.M. , Lee Chin Peng 
Published: November 2013

Abstract
Diabetes insipidus is a condition characterised by polyuria and polydipsia with excretion of diluted urine. Transient diabetes insipidus has been reported in pregnancy and is often associated with acute fatty liver of pregnancy, pre-eclampsia, HELLP syndrome and multiple pregnancy. Presenting symptoms can be vague. In our case, a primigravida with spontaneous monochorionic diamniotic twin pregnancy presented at 36+3 weeks in early labour. Severe hypernatremia was found in the patient and in both twins after a caesarean section was performed. Transient diabetes insipidus was diagnosed based on paired serum and urine osmolality. The hypernatremia was corrected gradually and 1-deamino-8D-arginine vasopressin was given. A high index of suspicion and early involvement of physicians and paediatricians are needed to avoid catastrophic consequences.
Phonetic Adaptation of Loanwords in Cypriot Turkish
Authors: Sultanzade Vügar 
Published: November 2013

Abstract
The strategies that have been developed for the incorporation of loanwords are mainly the same in Standard Turkish and its dialects. However, the adaptation process of these words has certain differences in Cypriot Turkish. The paper primarily focuses on the types and examples of phonetic adaptation of loanwords that show differences in this dialect and the standard language.
Pitch Alignment in Welsh English – The case of rising tones in Ceredigion
Authors: Quaino Stefano 
Published: November 2013

Abstract
Welsh English and the Celtic Englishes in general are known for their preference for rising tones in declaratives. However, the statement that Welsh English has a preference for rising tones is insufficient to explain its main prosodic characteristics.
The present investigation focuses on Ceredigion, a county in West Wales with a relatively high percentage of native Welsh speakers. Several excerpts have been collected from the interviews taken for the Survey of Anglo-Welsh Dialects (1977‒1979) and processed through Praat with the aim of identifying and analysing prosodic features of Ceredigion English. For the analysis, three fundamental elements will be considered: alignment of the stressed syllable, characteristics of the upward movement, and pitch peak. Through this detailed prosodic characterization of Ceredigion English, it will be shown that prosody is a distinguishing feature of Welsh English accent.
Was ist Russlanddeutsch und warum brauchen wir es? Einblicke und Ausblicke aus der Sicht der deutschen Dialektologie
Authors: Stellmacher Dieter 
Published: November 2013

Abstract
This article discusses the structure and state of the German language spoken today by the descendants of German immigrants to Russia in the 18th century. The (socio-) linguistic argumentation permits the following conclusion: The language based on German (Russlanddeutsch) may be a variety of the German language (russisches Deutsch) or a variety of the Russian language (deutsches Russisch), but it is the speakers in Russia who have the last word on this question. How they regard the language depends on their sense of identity, whether they feel Russian or German. Thus, future research into the linguistic situation of this group will best be served by an interdisciplinary approach and the a co-operation of linguists, psychologists, and historians.
The situation of dialectologists within the new integrated linguistics: the case of Atlantic Spanish
Authors: Chela-Flores Godsuno 
Published: November 2013

Abstract
Linguistics and Dialectology are two sides of the same coin: the former deals with the rigorous analysis of natural languages and the latter with concrete varieties of language in its cohesive and identifying social roles. Linguistics today is moving towards an integration of its various dimensions: phonology and phonetics are now so intricately tied that the unimodular phonetological approach is gaining ground rapidly; synchrony and diachrony are moving towards a reintegration, thus moving away from their parallel paths; and, finally, the so-called ‘non-structural’ elements of language are gradually being acknowledged as an integral part of the analysis that was traditionally reserved for the ‘structural’ ones. As linguistics moves, so does dialectology, since the latter has always been the laboratory of linguists, even if they have not formally accepted it as such. A new approach to dialectal matters must therefore move away from mere description and search for a more comprehensive analysis that confirms the essential inviolability of the binomial language-society. The traditional view of Hispanic linguistics and dialectology has been a victim of the dichotomic approach: conservative versus radical, Iberian versus American, high lands versus low lands, North-Central Castilian versus ‘Atlantic’ Spanish among others. This paper aims at taking an integrated approach to linguistics and dialectology, with its case study addressing the so called ‘Atlantic’ Spanish and the phonetological changes it is going through in search of a more satisfying explanation of short-term and long-term variability.
Membranes in motion: mitochondrial dynamics and their role in apoptosis
Authors: Ugarte-Uribe Begoña , García-Sáez Ana J. 
Published: November 2013

Abstract
Mitochondrial dynamics is crucial for cell survival, development and homeostasis and impairment of these functions leads to neurologic disorders and metabolic diseases. The key components of mitochondrial dynamics have been identified. Mitofusins and OPA1 mediate mitochondrial fusion, whereas Drp1 is responsible for mitochondrial fission. In addition, an interplay between the proteins of the mitochondrial fission/fusion machinery and the Bcl-2 proteins, essential mediators in apoptosis, has been also described. Here, we review the molecular mechanisms regarding mitochondrial dynamics together with their role in apoptosis.
On a Problem of Nonstationary 2D Motion of Micropolar Fluid in the Half-plane Subjected to a Uniform Magnetic Field when Normal Stresses and Tangential Velocities are Given on the Boundary
Authors: Abo-Dahab S. M. , El-Sirafy Ibrahim H. 
Published: November 2013

Abstract
In this paper, an attempt is made to obtain the effect of a uniform magnetic field on the solution of non-stationary motion of micropolar fluid in the half-plane when the normal stresses and tangential velocities are given on the boundary. The Laplace-Fourier transform technique is used to point out the solution by quadratures. Numerical results of the physical quantities such as tangential and normal velocities, pressure, microrotation, stresses and momentums included the influence of a uniform magnetic field are obtained and displayed graphically. The problem could be met in the study of the vibrations of a memberance or a plane contacting with the micropolar fluid.
Non-equilibrium Shock Structure Calculation with High-order Modified Navier–Stokes Equations
Authors: Zhao Wenwen , Chen Weifang 
Published: November 2013

Abstract
High-order modified Navier-Stokes (NS) equations are introduced to describe the transitional flow derived from Burnett equations considering the inaccurate simulation of shock structure using traditional NS continuum methods, particularly at high Mach numbers. This process is performed by defining the effective transportation coefficient, which is associated with Mach number, molecule propriety, and continuum failure criterion. Within this method, the linear Stokes and Fourier relationships are replaced by nonlinear constitutive relationships to describe transitional flow. The traditional NS equation formulation is preserved. The shock structures of both monatomic and diatomic gases are concentrated with different Mach numbers to validate the accuracy and effectiveness of the derived method. The comparison of shock structure with DSMC and Burnett equations shows that the high-order modified NS equations obtain better results than traditional NS equations in terms of shock wave, particularly at high Mach numbers. The modified NS equations also capture the significant features of Burnett equations in shock structure simulation.
On Testing the Equality of Mean and Quantile Effects
Authors: Bera Anil K. , Galvao Antonio F. , Wang Liang 
Published: November 2013

Abstract
This paper proposes tests for equality of the mean regression (MR) and quantile regression (QR) coefficients. The tests are based on the asymptotic joint distribution of the ordinary least squares and QR estimators. First, we formally derive the asymptotic joint distribution of these estimators. Second, we propose a Wald test for equality of the MR and QR coefficients considering a single fixed quantile, and also describe a more general test using multiple quantiles simultaneously. A very salient feature of these tests is that they produce asymptotically distribution-free nature of inference. In addition, we suggest a sup-type test for equality of the coefficients uniformly over a range of quantiles. For the estimation of the variance-covariance matrix, the use sample counterparts and bootstrap methods. An important attribute of the proposed tests is that they can be used as a heteroskedasticity test. Monte Carlo studies are conducted to evaluate the finite sample properties of the tests in terms of size and power. Finally, we briefly illustrate the implementation of the tests using Engel data.

Published: November 2013

Abstract
A UV-cured polyurethane (PU)/nano-silica composite with a flame-retarded coating system was obtained from the composition of nano-silica containing a UV-curable PU oligomer and a UV-reactive phosphonic acid [ethylene glycol methacrylate phosphate (EGMP)]. The UV-curable PU oligomer was prepared by an addition reaction of 2-hydroxyethyl methacrylate (2-HEMA) with an NCO-terminated PU pre-polymer; this was then mixed with a methanol dispersion of nano-silica. The UV-reactive phosphonic acid (EGMP) was prepared by a reaction of 2-HEMA with phosphorus pentoxide (P2O5). The curing reaction of the PU/nano-silica composite coating system was carried out by UV irradiation with the aid of a photoinitiator (2-hydroxy-2-methylpropiophenone). The thermal properties of these PU/nano-silica composite coatings were investigated by the measurements of dynamic mechanical analysis (DMA) and thermogravimetric analysis (TGA), respectively. A phosphorus (phosphonic acid) containing ingredient, EGMP in PU coating system that provides good adhesion to steel surface and flame retardation. Their physical properties (contact angle, hardness) and flame flammability [limiting oxygen index (LOI), UL-94 test] with various phosphorus contents (different dosages of EGMP) were also evaluated in this report.

ObjectiveTo stop smoking is commonly associated with significant weight gain, but the mechanisms for this are poorly understood. We assessed the effects of smoking cessation on body weight, insulin sensitivity, β-cell function, and appetite.Subjects and methodsTwenty-seven long-term smokers (n=27; nine females/18 males, 28±1 years, 22.9±0.6 kg/m2) attending an ambulatory smoking cessation program in a community hospital in Vienna, Austria were examined at baseline (Visit A; still smoking) and after a minimum of 3 months of smoking abstinence (Visit B;n=14); relapsed smokers were not followed up. Participants underwent 3-h oral glucose tolerance tests and body composition measurements at each study visit. Fasting (QUICKI) and dynamic (oral glucose insulin sensitivity (OGIS)) insulin sensitivity and β-cell secretion (insulinogenic index 140 (IGI40)) were calculated. Food intake was quantified with a free choice buffet. Fasting plasma concentrations of neuropeptide-Y (NPY), peptide-YY (PYY), glucagon-like peptide 1 (GLP1), leptin, ghrelin, and visfatin were measured.ResultsAfter >3 months' smoking abstinence, body weight, and fat mass were increased (+4 and +22% respectively,P<0.05) and fasting insulin sensitivity deteriorated (QUICKI: post, 0.37±0.02 vs baseline, 0.41±0.2;P<0.05), while OGIS remained unchanged throughout. IGI40 increased by 31% after >3 months' smoking abstinence (P<0.01). Carbohydrate ingestion increased after stopping smoking (P<0.05). NPY fasting levels were increased after >3 months (P<0.05), PYY, GLP1, leptin, ghrelin, and visfatin were unchanged.ConclusionSmoking cessation is associated with transient metabolic changes including increased β-cell secretion in response to glucose and fasting insulin resistance. These alterations may be associated with or contribute to the body weight gain after smoking cessation.
Components Associated With Home Visiting Program Outcomes: A Meta-analysis
Authors: Filene Jill H. , Kaminski Jennifer W. , Valle Linda Anne , Cachat Patrice 
Published: November 2013

BACKGROUND:
Although several systematic reviews have concluded that home visiting has strong evidence of effectiveness, individual evaluations have produced inconsistent results. We used a component-based, domain-specific approach to determine which characteristics most strongly predict outcomes.

METHODS:
Medline and PsycINFO searches were used to identify evaluations of universal and selective home visiting programs implemented in the United States. Coders trained to the study criterion coded characteristics of research design, program content, and service delivery. We conducted random-effects, inverse-variance–weighted linear regressions by using program characteristics to predict effect sizes on 6 outcome domains (birth outcomes, parenting behavior and skills, maternal life course, child cognitive outcomes, child physical health, and child maltreatment).

RESULTS:
Aggregated to a single effect size per study (k = 51), the mean effect size was 0.20 (95% confidence interval: 0.14 to 0.27), with a range of –0.68 to 3.95. Mean effect sizes were significant and positive for 3 of the 6 outcome domains (maternal life course outcomes, child cognitive outcomes, and parent behaviors and skills), with heterogeneity of effect sizes in all 6 outcome domains. Research design characteristics generally did not predict effect sizes. No consistent pattern of effective components emerged across all outcome domains.

CONCLUSIONS:
Home visiting programs demonstrated small but significant overall effects, with wide variability in the size of domain-specific effects and in the components that significantly predicted domain-specific effects. Communities may need complementary or alternative strategies to home visiting programs to ensure widespread impact on these 6 important public health outcomes.
Molecular Basis of Thrombophilia / MOLEKULARNE OSNOVE TROMBOFILIJE
Authors: Đorđević Valentina 
Published: November 2013

Summary
Thrombophilia is a multifactorial disorder, involving both genetic and acquired risk factors that affect the balance between procoagulant and anticoagulant factors and lead to increased thrombotic tendency. The severe forms of thrombophilia are caused by a deficiency of natural anticoagulants: antithrombin, protein C and protein S. The advances in DNA technology played an important role in the identification of the exact nature of these deficiencies and opened up new possibilities in genetic research and molecular diagnostics of thrombophilia. The major breakthrough came with the discovery of activated protein C resistance and the Factor V Leiden gene mutation. Shortly afterwards, a variant in the 3’ untranslated region of the Factor II gene (FII G20210A) associated with an increased concentration of Factor II in plasma was described. These two gene variants represent the most common thrombophilic genetic risk factors. Recently, a novel prothrombin mutation (c.1787G>T) was identified in a Japanese family with juvenile thrombosis. This mutation leads to impaired inhibition of mutant thrombin by antithrombin, proposing a new mechanism of thrombophilia named resistance to antithrombin. In the last decade, several prothrombotic genetic risk factors have been described, including gene variants associated with defects of natural coagulation inhibitors, increased levels of coagulation factors or their impaired inhibition and defects of the fibrinolytic system. However, most of them are not of diagnostic value, due to their minor or unknown impact on the thrombotic risk. Large-scale DNA analysis systems are now becoming available, opening a new era in the genetic studies of the molecular basis of thrombophilia.
Gerris Lacustris (Linaeus 1758) and Gerris Costae (Herrich-Schäffer 1850) Species - Habitat Relations on Mountainous Tributaries of Vişeu River (Maramureş, Romania)
Authors: Olosutean Horea , Ilie Daniela Minodora 
Published: November 2013

ABSTRACTSemi aquatic Heteroptera species from some mountainous tributaries of the Vişeu River were collected and their relations with habitat variables were investigated. Only two species, Gerris lacustris and Gerris costae were found, either one or both species, in almost half of the investigated sampling stations. Correlation analysis between samplings and habitat conditions showed that Gerris lacustris prefers small deep ponds or river banks with steep slopes and is easily adaptable to habitat changes, while Gerris costae is mostly found in large marshes with low, stagnant water and high amounts of vegetation. Both species are relatively tolerant to human impact in their habitat, Gerris lacustris more so. The two species are negatively correlated to each other, as an expression of competition between them. Principal Component Analysis resulted in two dominant factors explaining almost 60% of the habitat variation, and their graphic representation proved the observed correlations.
Utilization of Periphytic Natural Food as Partial Replacement of Commercial Food in Organic Tilapia Culture - An Overview
Authors: Milstein Ana , Naor Alon , Barki Assaf , Harpaz Sheenan 
Published: November 2013

ABSTRACT
This article summarizes the results obtained during five years of research at the Dor Fish and Aquaculture Research Station on partial replacement of commercial food by periphytic natural food in the culture of organic tilapia (hybrid Oreochromis aureus (Steindachner) x Oreochromis niloticus (L.)). Tilapia culture experiments were conducted in earth ponds with and without substrates, utilizing different substrates. Tilapias of sizes ranging from nursery to market-size fish were tested. Fish were stocked at densities common in organic fish culture, i.e. 5 tilapia/m2 at the nursery stage, 1.2-1.4 tilapia/m2 at the grow-out stage. Substrate experiments were carried out in 1 m3 cages protected from fish grazing to test growth of periphyton on materials with different characteristics. The findings show that the inclusion of substrates in the water body at an amount equivalent to 40-50% of the pond water surface, allows the reduction of commercial food input by 30-40% without significantly hampering fish growth rate. It is recommended to use rough, rigid, white substrates, on which periphyton growth of 2 g dry matter/m2/day has been measured. A figure and a table are provided as a tool to estimate periphyton contribution to the fish food ration, enabling the adjustment of the remaining daily food portion to be supplied as fish biomass increases during the culture period. Applying this technology will save food and money in the culture of organic tilapia, and it can also be appropriate in the conventional pond culture of tilapia as a method to reduce feed costs and increase sustainability.
