Published: February 2017

Precarious work is a form of work that is widespread today with the influence of neoliberal policies. This form of work includes the lack of job security and some social rights, as well as the fear of dismissal an ongoing job, even if the employee has a job. In recent years, precarious work has begun to be seen in the field of social work as well as being seen in every area with the contraction of the role of the public in working life. The purpose of this research is to evaluate the insecurity that has become widespread in the field of social work in recent years, in the eyes of the social workers, working in this field.For this purpose, in-depth interviews were conducted with 14 social workers who were working without precautions.Interviews were subject to content analysis by the authors and gathered under three subtopics. As a result of the research, it has been seen that precarious social workers feel themselves in an ambiguity on the individual level and on the social level they are away from working for the benefit of the client. The effects of precarious work are not only effect on an individual level, but Precarious work has also affected the social dimension, and it has preventing services for individuals. It is necessary to investigate more precisely the effects of precarious work on employees and clients, and to prevent the loss of rights in social services. ÖzetGüvencesiz çalışma, neoliberal politikaların etkisiyle günümüzde yaygın olarak görülen bir çalışma biçimidir. Bu çalışma biçimi, iş güvencesinden ve bazı sosyal haklardan yoksun çalışmayı içerdiği gibi aynı zamanda çalışanın bir işe sahip olsa bile sürekli bir işten çıkarılma korkusu yaşamasını da ifade etmektedir. Son yıllarda güvencesiz çalışma olgusu kamunun rolünün daralmasıyla her alanda görülmekle birlikte sosyal hizmet alanında da görülmeye başlanmıştır. Bu araştırmanın amacı da son yıllarda sosyal hizmet alanında yaygınlaşmaya başlayan güvencesizliği, bu alanda çalışan sosyal hizmet uzmanların gözünden değerlendirmektir. Bu amaçla güvencesiz çalışan 14 sosyal hizmet uzmanı ile derinlemesine görüşmeler gerçekleştirilmiştir. Görüşme dökümleri, yazarlar tarafından içerik analizine tabi tutulmuştur ve üç başlık altında toplanmıştır. Araştırma sonucunda güvencesiz çalışan sosyal hizmet uzmanlarının bireysel düzlemde kendilerini belirsizlik içinde hissettiği, toplumsal düzlemde ise müracaatçı yararına çalışmadan uzaklaştıkları görülmüştür. Güvencesiz çalışmanın etkileri sadece bireysel düzlemde hissedilmemekte, toplumsal boyuta taşınarak bireylerin hizmet alma ihtiyaçlarının önüne geçmektedir. Güvencesizliğin çalışanlar ve müracaatçılar üzerindeki etkilerinin daha kapsamlı bir şekilde araştırılması ve sosyal hizmet alanındaki hak kayıplarının önlenmesi gereklidir.

AbstractBarth syndrome (BTHS) is an X‐linked condition characterized by altered cardiolipin metabolism and cardioskeletal myopathy. We sought to compare cardiac and skeletal muscle bioenergetics in children, adolescents, and young adults with BTHS and unaffected controls and examine their relationships with cardiac function and exercise capacity. Children/adolescents and young adults with BTHS (n = 20) and children/adolescent and young adult control participants (n = 23, total n = 43) underwent 31P magnetic resonance spectroscopy (31P‐MRS) of the lower extremity (calf) and heart for estimation of skeletal muscle and cardiac bioenergetics. Peak exercise testing (VO2peak) and resting echocardiography were also performed on all participants. Cardiac PCr/ATP ratio was significantly lower in children/adolescents (BTHS: 1.5 ± 0.2 vs. Control: 2.0 ± 0.3, P < 0.01) and adults (BTHS: 1.9 ± 0.2 vs. Control: 2.3 ± 0.2, P < 0.01) with BTHS compared to Control groups. Adults (BTHS: 76.4 ± 31.6 vs. Control: 35.0 ± 7.4 sec, P < 0.01) and children/adolescents (BTHS: 71.5 ± 21.3 vs. Control: 31.4 ± 7.4 sec, P < 0.01) with BTHS had significantly longer calf PCr recovery (τPCr) postexercise compared to controls. Maximal calf ATP production through oxidative phosphorylation (Qmax‐lin) was significantly lower in children/adolescents (BTHS: 0.5 ± 0.1 vs. Control: 1.1 ± 0.3 mmol/L per sec, P < 0.01) and adults (BTHS: 0.5 ± 0.2 vs. Control: 1.0 ± 0.2 mmol/L sec, P < 0.01) with BTHS compared to controls. Blunted cardiac and skeletal muscle bioenergetics were associated with lower VO2peak but not resting cardiac function. Cardiac and skeletal muscle bioenergetics are impaired and appear to contribute to exercise intolerance in BTHS.

AbstractWe report on the 323 hours of nearly uninterrupted time series photometric observations of the DBV star GD 358 acquired with the Whole Earth Telescope (WET) during May 23 to June 8, 2000. We acquired more than 232 000 independent measurements and detected the non-radial g-modes consistent with degree ℓ = 1 and radial order 8 to 20 and their linear combinations up to 6th order. We also detect, for the first time, a high amplitude ℓ = 2 mode, with a period of 796 s. In the 2000 WET data, the largest amplitude modes are similar to those detected with the WET observations of 1990 and 1994, but the highest combination order previously detected was 4th order.
Atmospheric Extinction Corrections for WET Observations
Authors: Pakštienė E. , Solheim J. E. 
Published: February 2017

AbstractAccount of the extinction in the Earth’s atmosphere is an important part of the WET light curve reduction procedures. Usually, WET observations are not corrected for the second order extinction effects: the dependence of the extinction coefficient on spectral type and on air mass (the Forbes effect). The ignorance of these effects does not change seriously the derived pulsation amplitudes at the frequencies higher than 200 μHz but the increase of the noise at lower frequencies takes place. For obtaining the true extra-atmospheric magnitudes of stars, a modification of the extinction correction procedure is proposed. For photometry with the R647 phototube we recommend to use a filter cutting out the region below 310 nm, in order to decrease and stabilize the extinction coefficient. A method for estimation of spectral type of the comparison star from WET observations is proposed.
The WET Coverage - How Well Do We Do?
Authors: Solheim Jan-Erik 
Published: February 2017

AbstractThe Whole Earth Telescope collaboration is build solidly on the interest of the participants. One of the goals of the collaboration is to produce a high signal to noise, as continuous as possible, light curve for a selected target. During the nearly 15 years of existence the operation of the network has been based on what the members have been able to provide of local funds for their own participation, in addition to NSF grants to run the headquarters activities. This has led to a very uneven geographical distribution of participating groups and observatories. An analysis of the coverage of some of the last WET runs shows that we still have large holes in the coverage, and this leads to aliasing and loss of precision in our final products.

Published: February 2017

AbstractWe present analysis of the data collected during three years of photometric campaigns at the 91 cm Cassegrain telescope of the Catania Astrophysical Observatory to observe the pulsating subdwarf B star PG 1336-018. For this eclipsing binary system, we obtained a precise determination of the orbital period which turns out to be P = 0.10101599±0.00000002 days. Time-series photometry reveals pulsation periods near 174 and 184 seconds. We also discuss a preliminary analysis of the data obtained in 2002 for the pulsating subdwarf PG 1325+101.

AbstractSeven-color photometry in the Vilnius system has been obtained for 420 stars down to V = 16 mag in the area containing the overlapping open clusters NGC 1750 and NGC 1758 in Taurus. Spectral and luminosity classes, color excesses, interstellar extinctions and distances are given for 287 stars. The classification of stars is based on their reddening-free Q-parameters. 18 stars observed photoelectrically were used as standards. The extinction vs. distance diagram exhibits the presence of one dust cloud at a distance of 175 pc which almost coincides with a distance of other dust clouds in the Taurus complex. The clusters NGC 1750 and NGC 1758 are found to be at the same distance of ~760 pc and may penetrate each other. Their interstellar extinction A

Photoelectric Vilnius Photometry of Stars in the Mega Proper Motion Field KA 10
Authors: Bartašiutė S. 
Published: February 2017

Abstract
Photoelectric seven-color photometry in the Vilnius medium-band, system is obtained for 87 stars down to V≃13.0 in the Kiev proper motion field KA10 [l = 137°, b = -59°]. The size of the field is 1.4 square degrees. For each star, photometric spectral type, absolute magnitude, metallicity, and color excess due to interstellar reddening have been determined. These data, together with previous Vilnius photometry obtained in other seven KA fields at high Galactic latitudes, will be combined with radial-velocity measurements and available proper motions to yield space velocities and to investigate kinematical and chemical properties of the Galactic disk in the direction perpendicular to the Galactic plane.
Stellar Photometry at the Crossroads of the Two Centuries
Authors: Straižys V. 
Published: February 2017

Abstract
In the last century photometry was recognized as a powerful method for investigation of physical parameters of stars and of interstellar matter. Photometric investigations now cover the spectral range from the far ultraviolet to the far infrared. The article describes the most important landmarks in development of photometric classification of stars and the number of photometric survey projects accomplished by ground-based and space telescopes and including millions of point sources. The success of the future LSSD and Gaia projects will depend on the use of optimum photometric passbands.
Overview of Gaia Multi-Color Photometry
Authors: Høg Erik 
Published: February 2017

Abstract
Gaia will obtain multi-color photometry for astrometric and astrophysical purposes. A photometry in five broad bands and with high angular resolution will be obtained after every astrometric observation of a star, especially for the sake of correcting slight astrometric chromaticity errors of the optical system. A separate smaller telescope will obtain photometry in eleven passbands of medium width designed to serve the astrophysical analysis of the mission results. The medium-band photometry (MBP) has less angular resolution, but much longer effective integration time than the broad-band photometry (BBP).

Published: February 2017

Abstract
Metallicities and distances have been determined from Vilnius photometry for an in situ sample of nearly 650 stars in eight proper-motion fields at high Galactic latitudes. For half of these stars, radial velocities have been measured with the CORAVEL spectrometer, which allowed us to derive spatial velocities and Galactic orbits. In this contribution we present a status report on our results for the stellar content of the Galactic disk, with emphasis given to specific aspects of distinguishing the thick-disk stars from the old thin-disk population.

Abstract
We describe the efforts of the Taiwan-America Occultation Survey (TAOS) project to develop a data acquisition and analysis scheme for fast CCD imaging photometry. The TAOS project aims to conduct a census of the Kuiper-belt objects (KBOs) by detecting chance stellar occultation events by these small bodies in the outer reach of the solar system. An array of telescopes, each with fast optics (f/2) of 0.5 m aperture and equipped with a 2K CCD camera (3 square degrees FOV), have been set up in central Taiwan to monitor a couple thousand stars simultaneously. By reading out the CCD chip sequentially a few rows of pixels at a time (pause-and-shift), it is possible to achieve stellar photometry with a sampling rate up to several hertz. Here we report how such a setup has been used to observe the SX Phoenicis type variable CY Aqr to illustrate the potential usefulness of the TAOS database in stellar variability studies.

Abstract
In our study, we tested the existing and freely accessible soil databases covering a smaller geographical region surveyed and classified according to the Hungarian classification in order to approximate the WRB soil reference groups (RSG). We tested the results and applicability of approximation for the RSG with three different methods on 12 soil profiles. First, RSGs were assigned to Hungarian soil taxa based on results of previous correlation studies, secondly, a freely accessible online database of ISRIC was applied furthermore, and an automated reclassification developed and programmed by us was used, which takes the original soil data as input.
Some bioecological aspects of the rose aphid, Macrosiphum rosae (Hemiptera: Aphididae) and its natural enemies
Authors: Mehrparvar Mohsen , Mansouri Seyed Mozaffar , Hatami Bijan 
Published: February 2017

Abstract
The rose aphid, Macrosiphum rosae, is one of the most important pests on roses in the world and it causes economic damage. In this study, biology, seasonal population dynamics, and status of natural enemies of the rose aphid were studied. Seasonal population dynamics was studied by randomly sampling 10 shoots every week in two locations of Isfahan, Iran. Rose aphid with a high population density, both in spring (April and May) and in autumn (November), was observed on roses. The results showed that the rose aphid overwinters as parthenogenetic females and nymphs. This aphid migrates to a secondary host, Dipsacus fullonum (Dipsacaceae), in summer due to poor food quality of rose plants. Since sexual form and egg of the rose aphid were not observed in Isfahan, it is probably anholocyclic species with host alternation in this area. Natural enemies of the rose aphid include four species of Coccinellidae, three species of Syrphidae, two species of Chamaemyiidae, one species of Chrysopidae, a few species of Anthocoridae and Miridae, and one species of Cantharidae. One species of ectoparasite mite of Erythraeidae was also collected. In addition, four species of parasitoid wasps, Braconidae, were collected.
Laparoscopic Common Bile Duct Exploration for Choledocholithiasis During a Pregnancy: a Case Report
Authors: Lacis Janis , Rancane Ieva , Plaudis Haralds , Saukane Evita , Pupelis Guntars 
Published: February 2017

SummaryIn population studies, gallstones are found in 6.5% to 8.4% of nulliparous women, and in 18.4% to 19.3% of women with two to three or more pregnancies (7). Approximately 1 in 500 to 1 in 635 women will require non-obstetrical abdominal surgery during their pregnancies. Pregnancy induced physiological hormonal changes are associated with a decrease of gallbladder motility and increased cholesterol saturation of bile, leading to biliary stone formation (12,6,8). Surgical approach nowadays is the method of choice in the management of symptomatic gallstone disease during pregnancy, preferably if possible surgery should be postponed to second trimester (7,8).Preoperative radiologic imaging using magnetic resonance cholangiopancreatography is the golden standard for patients with suspected choledocholithiasis, however, its application during pregnancy is limited (9). Therapeutic endoscopic retrograde cholangiopancreatography (ERCP) may be used before, during or after laparoscopic cholecystectomy when it is indicated, but unfortunately, its application during pregnancy is associated with considerable number of complications concerning mother and fetus. Alternative approach has been developed and recommended for patients with the common bile duct (CBD) stones providing laparoscopic common bile duct exploration (LCBDE). Intraoperative cholangiography or intraoperative ultrasound (IOUS) are the methods currently used for detection of the CBD stones during laparoscopic cholecystectomy, however, IOUS can be considered as the method of choice during pregnancy (3).IOUS is a dynamic imaging modality that provides interactive and timely information during surgical procedures. Because the transducer is in direct contact with the organ being examined, high-resolution images can be obtained that are not degraded by air, bone, or overlying soft tissue (1).
Learners’ preferences towards Corrective feedback in writing assignments in tertiary education
Authors: Horbacauskiene Jolita , Kasperaviciene Ramune 
Published: February 2017

Abstract
For several decades, there has been a heated debate about the value of providing corrective feedback in writing assignments in English as a foreign language (EFL) classes. Despite the fact that corrective feedback in writing has been analysed from various angles, learners’ expectations regarding feedback given by language instructors are still to be considered, especially in different learning settings. Student attitudes have been found to be associated with motivation, proficiency, learner anxiety, autonomous learning, etc. (Elwood & Bode, 2014). Thus, the aim of this paper was to compare EFL learners’ attitudes towards corrective feedback and self-evaluation of writing skills in different learning settings. Students at two technological universities in France and Lithuania were surveyed and asked to complete an anonymous questionnaire combining the Likert scale and rank order questions. The results indicate that frequency of writing assignments seems to have little or no impact on students’ self-evaluation of writing skills. Moreover, although the two groups of students showed preference for feedback on different error types (e.g., feedback on structure vs. feedback on grammar), nevertheless, indirect corrective feedback with a clue was favoured by all the respondents.
