Abandoned Hungarian workers and the political economy of care work in Austria

In an era of globalization, the institutional system of mass migration is being substantially reorganized: its intensity and the variation in its forms are increasing. Global production chains combine diverse areas and different forms of work with varying wage levels by forming worldwide networks. In the Eastern European region, the growing level of emigration and relatively low fertility are leading to population loss. Hungary is not among the Eastern European countries with a high level of emigration; nevertheless, it faces serious challenges, particularly in some regions where after the transition losses of jobs were massive, and a greater proportion of people live under the poverty line than the national average. Our analysis is based on interviews, containing narrative and semi-structured parts, among domestic workers working mainly in Austria and Germany. The paper reveals possible causal mechanisms and the political economic structures behind this type of labour migration. We seek to understand how migrationrelated decisions are embedded in a global and highly unequal economic order.
Privacy-Preserving Compressive Sensing for Trajectory Recovery in Mobile Social Networks

Location based services (LBS) have experienced an explosive growth recently and evolved from utilizing a single user location to the whole trajectory of the user. However, due to the hardware and energy constraints, there are usually many missing data within a trajectory. In addition, as the trajectory information exposes the daily activities of a user, the privacy issue has been a major concern from mobile users. While there are effective state-of-the-art solutions that independently tackle the trajectory recovery and privacy preservation of user trajectories, yet no single design is able to tackle these two challenges simultaneously. Therefore in this paper, we propose a novel Privacy Preserving Compressive Sensing (PPCS) scheme to achieve both privacy preservation and accurate trajectory recovery. An encryption method named K-Vector Perturbation (KVP) is the major component of PPCS, which is proposed to perturb user trajectory with K other trajectories while maintaining the homomorphic encryption property for compressive sensingbased trajectory recovery. With PPCS, adversaries are only able to capture the encrypted data, and thus guarantees the privacy of mobile users. Furthermore, the homomorphic property guarantees that the recovery accuracy is comparable to state-ofthe-art compressive sensing designs. The performance of PPCS is extensively evaluated through trace-driven simulations, which are based on two publicly available mobility traces from Beijing and Shanghai with user mobility models including walk, bike, and car. The results demonstrate that our design is able to achieve a recovery accuracy of < 53 m and an average distortion (a commonly adopted metric to evaluate the privacy preservation strength) of more than 9, 000 m even when 50% original data are missing.
An Input-Output Focussed Approach to Characterize Freight Transport Models

The selection of an appropriate freight transport model for a specific research subject is based on a set of multidimensional criteria, as e.g. use-cases, geographical scope, methodological design, and input and output data of the model. We made an attempt to characterise different freight transport models, with a focus on the relevant input and output data. For this attempt, we used the SADT modelling concept (because of its clear input-output focus and its simplicity in terms of symbols and syntax), and introduced a set of binary general differentiators of freight transport models. We applied our characterization method to twelve selected freight transport models. The results of our approach may help other researchers to methodologically assess, which model(s) they might use, and which data these models require. Kunze, Teoh, Lindemann, Teo, Wulfhorst 2
Follow‐up of nutritional status and dietary survey in children with cow's milk allergy

The nutritional status of children with cow's milk allergy was followed during an elimination diet in 19 children (9 boys and 10 girls) beginning at the mean age of two years (range 0.6‐4.1 years). The cow's milk allergy had been verified in hospital by a challenge test at a mean age of 0.9 years (range 0.2‐1.9 years). Weight, height and laboratory indices to test protein, mineral and vitamin status were measured at three follow‐up visits at three‐month intervals. In addition to cow's milk allergy all these children had some other food allergies, and six of the 19 children were allergic to soy protein. Only two of the 19 children were given a soy‐based formula. In the diets of the other children, cow's milk was replaced by increasing amounts of other foodstuffs and supplementary calcium. At the beginning of the study the relative heights of the children were slightly retarded (– 0.6 SD) and remained unchanged during follow‐up (– 0.8 SD at the end of the study). The relative weights were found to be decreased during follow‐up (p < 0.05). There was a significant reduction in serum prealbumin values; eight of the 19 children showed abnormally low values. Low serum zinc values were seen in 12 children. Serum iron concentration was low in two children and two had high serum alkaline phosphatase values. Seven‐day food recording indicated that dietary intake of energy was below the recommendation in some children, but protein intake was high. Some children had low intakes of riboflavin. Correlations between dietary intake and nutritional status were not seen in the children with cow's milk allergy. Careful follow‐up of children with cow's milk allergy is indicated and should include the monitoring of relative height and weight, serum prealbumin, serum trace elements and individual diet prescriptions.
Sharing and Nonsharing of Brain Resources for Language and Music

Several theoretical and practical issues in cognitive neuroscience motivate research into the relations of language and music in the brain. Such research faces a puzzle. Currently, evidence for striking dissociations between language and music coexists with evidence for similar processing mechanisms (e.g., Peretz 2006; Patel 2008). The intent of this chapter is to initiate a dialog about how such confl icting results can be reconciled. Clearly, a coherent picture of language–music relations in the brain requires a framework that can explain both kinds of evidence. Such a framework should also generate hypothesis to guide future research. As a step toward such a framework, three distinct ways are put forth in which language and music can be dissociated by neurological abnormalities, yet have closely related cortical processing mechanisms. It is proposed that this relationship can occur when the two domains use a related functional computation and this computation relies on (a) the same brain network, but one domain is much more robust to impairments in this network than the other, (b) the interaction of shared brain networks with distinct, domain-specifi c brain networks, or (c) separate but anatomically homologous brain networks in opposite cerebral hemispheres. These proposals are used to explore relations between language and music in the processing of relative pitch, syntactic structure, and word articulation in speech versus song, respectively. Background: Why Study Language–Music Relations in the Brain? From the standpoint of cognitive neuroscience, there are at least fi ve distinct reasons to study language–music relations. Such studies are relevant to (a) comparative research on the neurobiological foundations of language, (b) debates over the modularity of cognitive processing, (c) evolutionary questions surrounding the origins of language and music, (d) the clinical use of From “Language, Music, and the Brain,” edited by Michael A.

A Vibrational Energy Harvesting Interface Circuit with Maximum Power Point Tracking Control

In this paper a CMOS interface circuit with MPPT (Maximum Power Point Tracking) control is presented for vibrational energy harvesting applications. In the proposed system a PMU (Power Management Unit) is employed at the output of a DCDC boost converter to provide a regulated output with low-cost and simple architecture. In addition, an MPPT controller using FOC (Fractional Open Circuit) technique is designed to harvest maximum power from vibration devices and increase efficiency of overall system. The AC signal from vibration devices is converted into a DC signal by an AC-DC converter, and then boosted through the DC-DC boost converter. The boosted signal is converted into a duty-cycled and regulated signal and delivered to loads by the PMU. A full-wave rectifier using active diodes is used as the AC-DC converter for high efficiency, and a DC-DC boost converter architecture using a schottky diode is employed for a simple control circuitry. The proposed circuit has been designed in a 0.35-μm CMOS process, and the designed chip occupies 915 μm × 895 μm. Simulation results shows that the maximum end-to-end power efficiency of the entire circuit is 83.4%.
STRESS CONTROLLED PIEZOELECTRIC ALN-MEMS-RESONATORS WITH MOLYBDENUM ELECTRODES FOR GHZ APPLICATIONS

We present design, fabrication and characterisation of piezoelectric AlN MEMS resonators with usage of molybdenum as material for the bottom electrode. The stress control during the sputter process and influence on the film quality of molybdenum by adding a thin (50nm) aluminium nitride nucleation layer beneath are shown. Two design variants with and without a structural silicon layer underneath the bottom electrode are presented. Equal layers in both design variants result in the possibility of comparing their performance RF properties like piezoelectric coupling factor and quality factor.
Vaspin promotes 3T3-L1 preadipocyte differentiation

Vaspin, a novel adipocyte factor secreted from visceral adipose tissues, is associated with obesity and insulin resistance and can regulate glucose and lipid metabolism, increase insulin sensitivity, and suppress inflammation; however, the underlying mechanisms remain unknown. Proliferation and maladaptive differentiation are important pathological mechanisms underlying obesity. This study aimed to evaluate the effects of vaspin on the proliferation and differentiation of preadipocyte 3T3-L1 cells and to explore the likely mechanisms responsible for 3T3-L1 differentiation. Vaspin was added to cultured 3T3-L1 cells, and the differentiation of adipocytes was evaluated using Oil Red O staining. The AKT signaling pathway and specific differentiation factors related to the differentiation of preadipocyte 3T3-L1 cells, peroxisome proliferator-activated γ and the CCAAT/enhancer-binding protein (C/EBP) family, were evaluated using reverse transcription polymerase chain reaction (RT-PCR) and western blot analyses during the early phase of differentiation. Additionally, adiponectin mRNA, interleukin-6 mRNA (IL-6 mRNA), and glucose transporter-4 (GLUT4) protein levels were measured in the differentiated adipocytes. The results indicated that vaspin promotes the intracellular accumulation of lipids and increases differentiation-related factors, including peroxisome proliferator-activated receptor γ, C/EBPα, and free fatty acid-binding protein 4 (FABP4), in a dose-dependent manner. Additionally, vaspin (200 ng/mL) increased the mRNA and protein levels of C/EBPβ, peroxisome proliferator-activated γ, C/EBPα, and FABP4. Moreover, compared with the control, significantly smaller eight-day differentiated adipocytes were observed, and these cells exhibited decreased IL-6 mRNA and increased GLUT4 mRNA levels; these results also indicated the potential of vaspin to promote the insulin-mediated AKT signaling pathway during the early phase of differentiation. In conclusion, vaspin is able to promote the differentiation of 3T3-L1 preadipocytes and may increase their sensitivity to insulin and suppress obesity.
EXPERIMENTAL CHARACTERIZATION OF A FLEXIBLE MEMBRANE FLAPPING-WING IN FORWARD FLIGHT

This paper presents a multidisciplinary experimental study to characterize a flexible flapping-wing by investigating the relationship between deformation and production of aerodynamic forces through series of wind tunnel experiments. The experimental setup consists of a flapping mechanism for singledegree-of-freedom flapping actuation and with input/output power and flapping kinematics measurement, a high responsive load cell for measuring the lift and thrust, and a unique digital image correlation system that consists of only one camera and a stereo vision spectroscope for capturing the structural deformation. Technical challenges of setting up experimental system for driving and measuring are resolved in this study, aerodynamic loads, wing kinematics, and wing deformations are synchronously measured. Intensive data analyses are performed to extract useful information from the experimental results, strong correlations between passive deformation and aerodynamic performance are revealed.
The Use of Corrective Feedback in the Japanese Communicative Learning Environment

This study was based on Lyster and Ranta’s (1997) research questions and coding methodology, which sought to identify the distribution of feedback, uptake and repair in communicative classroom environments. During this exploratory research project, 10 Japanese students from 4 different Oral Communications III classes at Komazawa were recorded for a total of 3 hours over a 5-week period in order to establish a Corrective Feedback framework for Time-Pair Practice (TPP). All Oral Communications classes use the Tasked-Based TPP methodology at Komazawa, where students are asked to research, create and discuss topics. There are preparation days and test days with the latter being the focus of the research into Corrective Feedback. On test days, students are asked to speak in random pairs in front of the class and have a thoughtful discussion related to the topic practiced in the prior class. If students make a mistake, they or their partner must correct the error or the teacher ends the conversation with implicit or explicit Corrective Feedback. The results from the research showed that explicit feedback was used most by the researcher, and although it led to the most amount of “uptake”, it also led to the highest number of “no uptake”. Furthermore, less explicit forms of correction, such as elicitation, clarification requests and recasts, were more successful in creating opportunities for learner uptake and repair. Student-generated Corrective Feedback reaffirmed the findings, as clarification requests were the most practical for promoting repair amongst peers.
Considering Connectivity for Visualization Design

A connected life is changing the way people deal with data. Information can be collected, received, and analyzed almost anywhere. As a result, people can use decision-making in a broader variety of situations. For example, dietary trackers inform what people order for lunch; mobile devices allow environmental researchers to collect large amounts of complex data in the field; businessmen can analyze multivariate sales data on their phones to respond to major economic events.
Histochemical and autoradiographic investigation of the serous cells of the human bronchial glands

THE subrnucosal glands of the human trachea and bronchus include both mucous and serous cells. In any one section the serous cells may amount to 50 per cent. of the gland area (Lamb, 1968), but remarkably little is known of the nature of their secretion
Transdimensional tomography with unknown data noise

SUMMARY A meaningful interpretation of seismic measurements requires a rigorous quantification of the uncertainty. In an inverse problem, the data noise determines how accurately observations should be fit, and ultimately the level of detail contained in the recovered model. A common problem in seismic tomography is the difficulty in quantifying data uncertainties, and thus the required level of data fit. Traditionally, the complexity of the solution model (defined by both the number of basis functions and the regularization) is defined arbitrarily by the user prior to inversion with only limited use of data errors. In the context of multiscale problems, dealing with multiple data sets that are characterized by different noise variances and that span the Earth at different scales is a major challenge. Practitioners are usually required to arbitrarily weigh the contribution of each data type into the final solution. Furthermore, the basis functions are usually spatially uniform across the velocity field and regularization procedures are global, which prevents the solution model from accounting for the uneven spatial distribution of information. In this work we propose to address these issues with a Hierarchical Bayesian inversion. The new algorithm represents an extension of the transdimensional tomography to account for uncertainties in data noise. This approach has the advantage of treating the level of noise in each data set, as well as the number of model parameters, as unknowns in the inversion. It provides a parsimonious solution that fully represents the degree of knowledge one has about seismic structure (i.e. constraints, resolution and trade-offs). Rather than being forced to make decisions on parametrization, level of data fit and weights between data types in advance, as is often the case in an optimization framework, these choices are relaxed and instead constrained by the data themselves. The new methodology is presented in a synthetic example where both the data density and the underlying structure contain multiple length scales. Three ambient noise data sets that span the Australian continent at different scales are then simultaneously inverted to infer a multiscale tomographic image of Rayleigh wave group velocity for the Australian continent. The procedure turns out to be particularly useful when dealing with multiple data types with different unknown levels of noise as the algorithm is able to naturally adjust the fit to the different data sets and provide a velocity map with a spatial resolution adapted to the spatially variable information present in the data.
MODELING , CONTROL AND HARDWARE-INTHE-LOOP SIMULATION OF A GENERIC TILTING MULTIROTOR

In general, standard multi-copters are classified as an underactuated system since their number of control inputs are insufficient to allow the control of position and orientation independently. In this context, this paper deals with the dynamical modeling of a tilted rotor multi-copter aerial vehicle and the project of a trajectory tracking controller using modern control techniques. The dynamic model is developed using Newton Euler Laws and it is assumed that each rotor is capable of two different movements (tilt laterally and longitudinally) introducing more control inputs to the system. Then, the equations of motion are linearized around the trimmed operating conditions (based on mission applications). Finally, linear modern MIMO (Multi-Input Multi-Output) control techniques are applied in order to allow the aircraft to follow a pre-defined trajectory. The control law is validated by a hardware-in-the-loop implementation using a real microcontroller integrated with a numerical real time simulation.
Is Sketching Still Relevant in Virtual Design Studios

Sketching, as a particular subset of drawing, has for a long time, been valued within design activity. Although they can appear rough, inaccurate or incomplete, sketches have been presented as both valuable output from, and evidence of, essential activity in designing by individuals and groups. This paper reflects on this value and asks whether sketching is relevant today, given the advances in computing and communications technology seen in modern virtual design environments. Is it time to let go of the metaphor of drawing or can this ancient human capability still tell us something relevant for the improvement of the virtual design studio? While freehand line drawings may not have the same importance in current virtual design studios the support of incompleteness, ambiguity and shared meaning in solution-focused and problem-focused thinking remains essential. The paper proposes that attention to 'graphic acts' has improved our understanding of sketching within collaborative designing. A particular type of fast, transitory 'thumbnail' sketch would appear to be important. If this is so then attention to its modern counterpart in the latest 3D, multi-user, immersive virtual design studios is overdue if they are to support the cognitive processes of creativity vital to design.
HAART and progression to high-grade anal intraepithelial neoplasia in men who have sex with men and are infected with HIV.

BACKGROUND Human immunodeficiency virus (HIV)-seropositive men who have sex with men (MSM) are at risk for anal intraepithelial neoplasia (AIN) and cancer. The goal of this study was to identify risk factors associated with high-grade AIN (AIN-2,3) in HIV-positive MSM, including the receipt of highly active antiretroviral therapy (HAART). METHODS A cohort study involving 247 HIV-seropositive MSM receiving HAART or initiating HAART was followed up every 6 months for 3 years with human papillomavirus (HPV) testing and high-resolution anoscopy to identify predictors of AIN-2,3 by Cox regression analysis and period prevalence logistic regression. RESULTS AIN-2,3 was observed during the study in 132 (53%) of 247 participants. The progression rate to AIN-2,3 from a lesser abnormality at baseline was 12.8 cases per 1000 person-months (95% confidence interval [CI], 9.8-16.5 cases per 1000 person-months). The risk of AIN-2,3 increased with age (odds ratio [OR], 3.09 [95% CI, 1.12-8.52] for men 40-49 years of age and 4.78 [95% CI, 1.29-17.73] for men >50 years of age, compared with men <40 years of age) and for men whose CD4+ cell counts were <50 cells/mm(3) before starting HAART (OR, 14.40 [95% CI, 1.45-143.58]). Men who had been receiving their current HAART regimen for >4 years had a marginally significant lower risk of AIN-2,3 after adjustment for HPV (OR, 0.28 [95% CI, 0.07-1.06]) compared with those treated for <4 years. Anal HPV type 16 (HPV16) or type 18 (HPV18) infections (OR, 14.18; [95% CI, 3.51-57.32]) and HPV16 and HPV18 co-infection (OR, 31.03 [ 95% CI, 5.68-169.60]) were strongly associated with progression to AIN-2,3. CONCLUSION HPV16 and HPV18 infections and a low nadir CD4+ cell count increase the risk of AIN-2,3. Receiving the same HAART regimen for >4 years may contribute some benefit against AIN-2,3.
Food And Feeding Habits Of Freshwater Teleost : Ompok Bimaculatus

The food composition of Ompok bimaculatus, Xenentodon cancila, Puntius sarana and Labeo boggut were studied for a period of one year i.e., from May, 2012 to April, 2013. All the four fishes feed on both types of foods plant origin as well as animal origin. The food and feeding habit of three freshwater fishes has revealed that O. bimaculatus and X. cancila are carnivorous, Puntius sarana is eury-omnivorous and Labeo boggut is a herbivorous fish. In O. bimaculatus the phytoplanktonic groups are the main contributors of the fish food were 54.37%, macro-invertebrate 21.69%, zooplankton 17.82%, vertebrate 0.92% and miscellaneous items 5.17%. The phytoplankton was found dominant group (58.05%) in X. cancila followed by, zooplankton 23.39%, macro-invertebrate 12.14%, vertebrate 1.22% and miscellaneous items 5.19%. Total food items of Puntius sarana, divided into four groups phytoplankton (67.94%) followed by zooplankton (19.31%), macroinvertebrate (7.61%) and miscellaneous items (5.15%). phytoplankton was the first preference of the Labeo boggut and it was observed for 84.95% of the total food items. The percent composition of remaining groups was zooplankton 10.13%, macroinvertebrate 0.94% and miscellaneous items 3.97%.
