PATELLINS are regulators of auxin-mediated PIN1 relocation and plant development in Arabidopsis thaliana
Authors: Tejos Ricardo , Rodriguez-Furlán Cecilia , Adamowski Maciej , Sauer Michael , Norambuena Lorena , Friml Jiří 
Published: July 2017

ABSTRACT
Coordinated cell polarization in developing tissues is a recurrent theme in multicellular organisms. In plants, a directional distribution of the plant hormone auxin is at the core of many developmental programs. A feedback regulation of auxin on the polarized localization of PIN auxin transporters in individual cells has been proposed as a self-organizing mechanism for coordinated tissue polarization, but the molecular mechanisms linking auxin signalling to PIN-dependent auxin transport remain unknown. We used a microarray-based approach to find regulators of the auxin-induced PIN relocation in Arabidopsis thaliana root, and identified a subset of a family of phosphatidylinositol transfer proteins (PITPs), the PATELLINs (PATLs). Here, we show that PATLs are expressed in partially overlapping cell types in different tissues going through mitosis or initiating differentiation programs. PATLs are plasma membrane-associated proteins accumulated in Arabidopsis embryos, primary roots, lateral root primordia and developing stomata. Higher order patl mutants display reduced PIN1 repolarization in response to auxin, shorter root apical meristem, and drastic defects in embryo and seedling development. This suggests that PATLs play a redundant and crucial role in polarity and patterning in Arabidopsis.

ABSTRACT
Here, we studied the potential role of inorganic polyphosphate (polyP) as an energy source for ADP and ATP formation in the extracellular space. In SaOS-2 cells, we show that matrix vesicles are released into the extracellular space after incubation with polyP. These vesicles contain both alkaline phosphatase (ALP) and adenylate kinase (AK) activities (mediated by ALPL and AK1 enzymes). Both enzymes translocate to the cell membrane in response to polyP. To distinguish the process(es) of AMP and ADP formation during ALP hydrolysis from the ATP generated via the AK reaction, inhibition studies with the AK inhibitor A(5′)P5(5′)A were performed. We found that ADP formation in the extracellular space occurs after enzymatic ATP synthesis. After exposure to polyP, a significant increase of the ADP level was observed, which is likely to be been catalyzed by ALP. This increase is not due to an intensified ATP release via exocytosis. The ATP level in the extracellular space of SaOS-2 cells is strongly increased in response to polyP, very likely mediated by the AK. We propose that the ALP and AK enzymes are involved in the extracellular ADP and ATP synthesis.
The implementation of object-centred learning through the visual arts: Engaging students in creative, problem-based learning
Authors: Parton Anthony , Newton Douglas , Newton Lynn 
Published: July 2017

Abstract
Many museums now allow more opportunities for students to interact with their artefacts, often in store. At the same time, digital technologies now make it easier for those students to access information about those artefacts, interpret it, and construct and communicate their story in imaginative ways. The potential for learning about and through is evident. This article describes how this potential was realized in a collaboration between an Oriental museum and undergraduates studying a visual arts module at the University of Durham, UK. It describes some guiding educational principles, the students’ interaction with art objects, their research process and logs, and the presentation of their understandings in podcasts. Their responses achieved the aims of high levels of motivation, the construction of understandings (and their limits), imaginative communication, heightened information technology skills, and personal satisfaction. That this approach could be usefully applied elsewhere is indicated, along with some limitations.
The relevance of art-oriented processes in the formation of architects and engineers
Authors: Grech Anton 
Published: July 2017

Abstract
The University of Malta recently introduced a one-year Diploma Course in Design Foundation Studies with an art-oriented, artist-led, practice-based programme as a preparatory and integral part of the degree courses in Architecture and Civil/Structural Engineering. The article explains the rationale behind the introduction of this new course and its methodology. It analyses why perception, coupled with basic drawing skills, are important for students of architecture and engineering. It shows how the translation of the drawing representing the concept into a threedimensional model relates to their future work. The Sculpturehouse exercise serves as an example illustrating the relation between sculpture and architecture/engineering and the relevance of a haptic experience. Observations made by the author and other members of the academic staff of the Faculty for the Built Environment as well as communications from students who have attended the course lead to conclusions that are sustained by the results of a questionnaire.
Readings of the contemporary in art education: Simultaneity and ambivalence in video art
Authors: Pillar Analice Dutra 
Published: July 2017

Abstract
The article discusses how the simultaneity of actions and languages and ambivalence in ways of being and acting, present in everyday experiences, are written into audio-visual productions of contemporary art. The video art Para Dentro and the reading of this work by a group of children were analysed using discursive semiotics, as related to the effects of meaning in audio-visual texts of contemporary art, and the processes of appropriation and redefinition of images and sounds, during art education on the reading of images. Analysis of this video art highlights its articulation, through overlays, of the various languages that constitute the audio-visual text and the presentation of images and sounds ambiguously, creating effects of ambivalence. What most disturbed the children during their reading were the visual and sound ambivalences. The results indicate the need to reflect, in school, on contemporary audio-visual narratives, seeking to understand the present moment.

A Travelling Lamaštu
Authors: Ermidoro Stefania 
Published: July 2017

AbstractThe article presents a study of the text and iconography of the item previously identified by Farber as “Lamaštu-Amulett Nr. 70F”. In 1989, Farber described the amulet and published its textual content by means of some photographs. Recently, however, the present author had the opportunity to inspect the same item in a private collection in Italy. The results of the new collation are provided here, including a description of the specific characteristics and technical features of the object. It is argued here that the amulet is without a doubt a modern copy, which accurately duplicates an ancient piece: at the end of the article, photos provide evidence of all the surfaces of the object.
Processing-independent proANP measurement for low concentrations in plasma: reference intervals and effect of body mass index and plasma glucose
Authors: Mark Peter D. , Hunter Ingrid , Terzic Dijana , Goetze Jens P. 
Published: July 2017

Abstract

Background:
Decreased concentrations of pro-atrial-derived natriuretic peptides (proABP) in plasma have been associated with obesity and suggested as a predictor of type 2 diabetes. However, assays for measuring proANP are generally aimed to quantitate higher concentrations of proANP associated with cardiac disease. Therefore, we aimed to measure plasma proANP concentrations in a non-obese Scandinavian reference material and evaluate potential associations of plasma proANP with body mass index (BMI) and plasma glucose, respectively.

Methods:
We report an optimized processing-independent assay (PIA) for proANP in the lower concentration range. The assay was optimized by raising the amount of radioactive tracer and modifying the mixing ratio of resuspended plasma and buffer. Blood samples from a Scandinavian plasma cohort of 693 healthy subjects were then analyzed and age and gender-specific reference intervals were determined.

Results:
Simple linear regression analyses of proANP and both BMI and plasma glucose in fasting subjects displayed insignificant associations. Multiple regression analyses supported these findings. However, a higher median plasma concentration of proANP was noted among women <50 years compared to men, whereas no gender-specific differences were seen in other age groups.

Conclusions:
Our results show that in a healthy non-obese population, BMI and plasma glucose in fasting subjects do not affect plasma proANP concentrations. Our method should be considered for future studies on low proANP concentration studies, e.g. in obesity and diabetes.
The Globar War: The EU’s Apple Tax Case
Authors: Rougé Jean-François 
Published: July 2017

AbstractIt is often said that globalization is just a new form of war between nations; an economic war. It is also a tax war; fiscal policies are a central point of the competition for territories’ attractiveness (ROUGÉ et CHOPOV 2016). But the global tax war is not only another form of interstates conflict; it is also a brand new kind of war between global firms and state to share the burden of civil society. The aim of this paper is to clarify what is at stake in this war to be able to fight it.

Published: July 2017

Abstract
We are witnessing that the labor market indicators of the Republic of Srpska have been deteriorating for years. Unemployment rates are up to three times higher than the already high European average, with no prospect of changing the situation in the near future. Deterioration in the labor market with respect to people younger than 30 years of age bears particular significance. There is a notable gap between the reduction of unemployment rate and the increase of employed people from this population group. The question is: Where (and whether) are the young (educated) people disappearing from the labor market of the Republic of Srpska? The authors provide an analysis of the main indicators of the Republic of Srpska’slabor market, with the aim of recognizing the main tendencies and problems existing at the market, as well as the need to define adequate measures for their resolution.
Synthesis of Conformal Phased Antenna Arrays With A Novel Multiobjective Invasive Weed Optimization Algorithm
Authors: Li Wen Tao , Hei Yong Qiang , Shi Xiao Wei 
Published: July 2017

AbstractBy virtue of the excellent aerodynamic performances, conformal phased arrays have been attracting considerable attention. However, for the synthesis of patterns with low/ultra-low sidelobes of the conventional conformal arrays, the obtained dynamic range ratios of amplitude excitations could be quite high, which results in stringent requirements on various error tolerances for practical implementation. Time-modulated array (TMA) has the advantages of low sidelobe and reduced dynamic range ratio requirement of amplitude excitations. This paper takes full advantages of conformal antenna arrays and time-modulated arrays. The active-element-pattern, including element mutual coupling and platform effects, is employed in the whole design process. To optimize the pulse durations and the switch-on instants of the time-modulated elements, multiobjective invasive weed optimization (MOIWO) algorithm based on the nondominated sorting of the solutions is proposed. A S-band 8-element cylindrical conformal array is designed and a S-band 16-element cylindrical-parabolic conformal array is constructed and tested at two different steering angles.

Published: July 2017

AbstractTwo 2,6-pyridinedicarboxamide derivatives containing arylboronic acid fragments were prepared and fully characterized including X-ray crystal diffraction analysis of a pinacol ester. These compounds are potential bifunctional receptors for sugars and anions. Acid dissociation and stability constants for complexation of both receptors with glucose and fructose were determined by potentiometric titrations in aqueous DMSO. Also, binding of alizarin red S indicator was studied spectrophotometrically and a highly sensitive detection of fructose by an indicator displacement assay was proposed. Complexation with anions was studied by1H NMR titrations in DMSO-d6. Binding of acetate anion occurs only via hydrogen bonding to OH groups of boronic acid fragments and does not affect signals of NH protons but chloride anion induces large shift of the signals of NH protons and small shifts of the signals of OH groups. This behavior makes possible anion discrimination based on preference in the type of binding site rather than simply on anion basicity as is typical for majority of neutral hydrogen bonding anion receptors.
A Novel Performance Enhancement Scheme for Doubly-Fed Induction Generator-Based Wind Power Systems under Voltage Sags and Swells
Authors: Das Tapash , Zhang Jingxin , Pota Hemanshu 
Published: July 2017

AbstractWind power is a major contributor in the renewable energy sector but it faces some issues regarding modern grid-code compliance. Popular wind power systems based on Doubly-Fed Induction Generators (DFIG) need additional protection under grid voltage disturbances. They also need to support the grid voltage under such transient occurrences. This paper presents a novel performance enhancement scheme for DFIGs subjected to symmetrical and asymmetrical voltage sags and swells at the Point of Common Coupling (PCC). The scheme comprises a protection system and a reactive power management system working simultaneously under the command of a supervisory control system. The protection system protects the DFIG converter by limiting the overcurrent in the Rotor Side Converter (RSC) of the DFIG and keeping the dc-link capacitor voltage within an acceptable range; whereas, the reactive power management supports the grid voltage by either injecting or absorbing reactive power to reduce the magnitude of voltage sags and swells. It is found that the performance of the DFIG wind generation system improves significantly under the proposed scheme. A grid-connected 9-MW DFIG wind farm is used for simulation in MATLAB/Simscape Power Systems.
English, motility and Ismaili transnationalism
Authors: Bolander Brook 
Published: July 2017

AbstractThe transnational Ismaili community is made up of local communities of Ismailis living in over 25 countries around the world. Despite diversity within and between these communities, the 2.5–12 million Ismailis worldwide share a common identity as Ismaili. Various structures and resources are used to construct and maintain the community. These include an official language – English. In this article, I aim to explore the role of English in connection with Ismaili transnationalism. Drawing on ethnographic data collected during fieldwork in Northern Pakistan and Eastern Tajikistan, and on data taken from digital spaces, I will focus on the movement of local Ismailis away from Northern Pakistan and Eastern Tajikistan, and on the movement of people and ideas to Northern Pakistan and Eastern Tajikistan. I will thereby argue for the importance of including non-mobile individuals in conceptualizations of Ismaili transnationalism. In doing so, I will apply the concept of “motility”, which points to interconnections between social and spatial mobility, and highlights the potential for mobility; and I will underline the role local settings play for transnational processes. In the course of the article, I also demonstrate that Ismaili transnationalism is not homogeneous. Instead, certain people, places and spaces emerge as more relevant to its construction and maintenance. This becomes coupled with access to English and has implications for this issue’s focus on the relationship between South and Central Asian spaces.
Social Transfers and Income Inequality in Bulgaria
Authors: Mihaylova Svilena , Bratoeva-Manoleva Silviya 
Published: July 2017

AbstractThe paper analyzes the distributional effects of social transfers in Bulgaria in the period 2000-2014, using income inequality decomposition by factor components. The results suggest that social transfers mitigate income inequality, but this effect varies depending on the type of transfer. Pensions exert the strongest influence due to their significant share in total income, which also rises over time. Family allowances are pro-poor in nature, but because of their small share in beneficiaries’ total income, their impact on overall inequality is much weaker. “Other social benefits” have the weakest inequality-reducing effect, which is due to their higher concentration towards the richest decile and increasing share in total income. Despite the inequality-decreasing impact of social transfers, we argue that they should not be regarded as the sole remedy for the sharp income disparities in the country, but need to be accompanied by relevant active labor market policies.
Is Real Depreciation or More Government Deficit Expansionary? The Case of Slovenia
Authors: Hsing Yu 
Published: July 2017

Abstract
The purpose of this paper is to examine the impacts of the real exchange rate, the government deficit and other relevant variables on aggregate output in Slovenia. Few of the previous studies have applied the AD/AS model to examine the impacts of major macroeconomic variables on aggregate output. This paper makes contributions to the literature by applying a rigorous model to examine how real GDP is affected by the real exchange rate, fiscal policy and other related variables. The exponential GARCH model is applied in empirical work. The paper finds that real depreciation of the Euro may affect Slovenia’s aggregate output positively or negatively and that more central government deficit as a percent of GDP does not affect aggregate output. In addition, Slovenia’s aggregate output is positively associated with the real stock price, the real oil price and real total labor cost or wage and is negatively influenced by the real lending rate and the expected inflation rate. Recent real depreciation of the Euro would help Slovenia’s aggregate output whereas expansionary fiscal policy would not be effective in stimulating the economy.
Evaluating the Use of Personal Networks to Circumvent Formal Processes: A Case Study ofVruzkiin Bulgaria
Authors: Williams Colin C. , Yang Junhong 
Published: July 2017

AbstractThe aim of this paper is to evaluate the prevalence and distribution of the use of personal connections to circumvent formal procedures by soliciting favours for and from others, known as vruzki, and how this can be explained and tackled. Reporting data from 2,005 face-to-face interviews conducted in late 2015 in Bulgaria, the finding is that 30 per cent of respondents had used vruzki in the 12 months prior to the survey, particularly when accessing medical services and finding a job. Estimating a logit model and then calculating the marginal effects, the population groups significantly more likely to have used vruzki are those whose norms, values and beliefs are not in symmetry with the formal laws and regulations, perceiving the penalties and detection risks as higher, those reporting their financial situation as very comfortable, and the highest income groups, but also younger people, the unemployed, and those living in larger households. The paper concludes by discussing the theoretical and policy implications along with the future research required.
The Unemployed Workers’ Perceptions of Stress and Employment Prospects in Macedonia: The Role of Alternative Adjustment Mechanisms
Authors: Nikoloski Dimitar , Pechijareski Ljupcho 
Published: July 2017

Abstract
Depressed labour market conditions in Macedonia manifested by high and persistent unemployment rate, strong segmentation and prevailing long-term unemployment is considered as a heritage of more than two decades long period of transition. Unemployment has a number of negative consequences such a decreased income which is assumed to influence the subjective experience of unemployment. The negative macroeconomic shocks in Macedonia have been mitigated due to the strengthened role of alternative labour market adjustment mechanisms such as: employment in the informal sector, emigration and inactivity. However, their impact on the unemployed workers’ perceptions of stress and future labour market prospects is less clear-cut. In this paper we use results from a survey carried out on a sample of unemployed workers in Macedonia in order to identify the psychological implications of unemployment by assessing the perceived stress and employment prospects with particular reference to the role of alternative labour market adjustment mechanisms.
