The nature, extent and impact of educator targeted bullying on school teachers in West Malaysia

ABSTRACT This study examines the nature, prevalence and impact of educator targeted bullying (ETB) in a sample of 575 Malaysian school teachers. Specifically it was predicted that ethnicity may be related to exposure to ETB; that frequency of exposure would vary by type of ETB; that there would be tenure-related differences in terms of exposure and burnout; and that teaching experience could moderate the exposure-burnout relationship. Results suggest that less severe forms of ETB are more prevalent than physical forms; and that educators with increased teaching experience are less exposed to ETB. ETB exhibits a negative impact on burnout; and is strongest for student-related burnout. Increased experience buffers the ETB–student-related burnout relationship while ethnicity is unrelated to exposure to ETB.
D6.1: 3D Media Tools – Report – Version A

This document summarizes the research achievements of WP6 for the tasks of off-line extraction of 3D audio-visual content (T6.1) as well as the free viewpoint scene reconstruction and rendering (T6.3). T6.2 and T6.4 are not mentioned because the former, which deals with 3D media coding, was foreseen to start at the end of the first year, and the latter, which focuses on standardisation (in the context of WP6), will have its results reported in D9.3 at the end of the project. A preliminary version of this report was submitted in January 2015 in order to support the first years project review. The current document extends this interim version. Changes are listed in the document version overview table.
How to find a good submatrix

Pseudoskeleton approximation and some other problems require the knowledge of sufficiently well-conditioned submatrix in a large-scale matrix. The quality of a submatrix can be measured by modulus of its determinant, also known as volume. In this paper we discuss a search algorithm for the maximum-volume submatrix which already proved to be useful in several matrix and tensor approximation algorithms. We investigate the behavior of this algorithm on random matrices and present some its applications, including maximization of a bivariate functional.
Stress, depression and role conflict in working mothers

It is believed that depression will be the number one cause of disability worldwide in the year 2020, and stress will be a contributing factor. This is significant for South Africa which is considered to be one of the most highly stressed societies in the world with many social problems that contribute to stress and depression. One of the factors that research has indicated may lead to stress is work/home role conflict. This is often considered stressful for working mothers as they tend to carry a greater domestic burden. This study aimed to explore the levels of and interrelationships between stress, depression and work/home role conflict in a sample of 59 working mothers. Mediating factors such as coping skills and social support were also explored. The study found that for this sample work/home role conflict was not significant but that half of the sample reported features of depression. There was a positive correlation between stress and depression and negative correlations between coping, support, stress and depression. South African Psychiatry Review - May 2002
Gauge theory and Stein fillings of certain 3-manifolds

In the following we show that a Stein filling S of the 3-torus T3 is homeomorphic to D2 \times T2. In the proof we also show that if S is Stein and \partial S is diffeomorphic to the Seifert fibered 3-manifold -S (2,3,11) then b1(S)=0 and QS=H. Similar results are obtained for the Poincare homology sphere \pm S (2,3,5); in studying these fillings we apply recent gauge theoretic results, and prove our theorems by determining certain Seiberg-Witten invariants.
Interest Rate Policy and the Price Puzzle in a Quantitative Business Cycle Model

In the empirical literature, monetary policy shocks are commonly measured as an innovation to a short-term nominal interest rate. In contrast, the majority of monetary business cycle models treats a broad monetary aggregate as the central bank's policy measure. We try overcome this disparity and present a business cycle model which allows to examine the effects of innovations to a non-contingent nominal interest rate rule. To obtain unique rational expectations equilibria we assume that changes in money supply are brought about open market operations. In addition to working capital, we consider staggered prices which enables real marginal costs to vary. Consistent with the empirical findings of Barth and Ramey (2000), the model predicts that real marginal cost and inflation rise in response to positive interest rate innovations. The mechanism corresponds to their 'Cost Channel of Monetary Transmission' and replicates typical monetary VAR results, including the puzzling behavior of prices.
Learning process promoted by sensemaking and trust: a study related to unexpected events

The objective of this study is to understand the interrelations among the micro processes which comprise sensemaking (WEICK, 1995) and the construction of trust (LUHMANN, 1996) in unexpected events. Unexpected events transcend routine and planning orders. However, when they happen, they demand from the organizations solutions as efficient and effectual as those programmed events. The methodology consists of the analysis of six semi-structured interviews and Conversation Analysis (CA) of the main extracts of the conversation between the agents and the supervisor from the beginning of event until its conclusion (recorded in real time). As empirical evidence, an unexpected event at the Operations Center of the Brazilian Electrical System (COS) of an important Brazilian state, on September 24 and 25, 2009 is investigated. The conclusion is that there is an interrelationship between micro processes of sensemaking, considered as ambiguity, experience and interactions, and the micro processes of trust, considered as complexity, familiarity and social behavior.
KlimaSeniorinnen: lessons from the Swiss senior women's case for future climate litigation

As older women are particularly vulnerable to climate change impacts, a group of senior women in Switzerland founded the association KlimaSeniorinnen Schweiz (Senior Women for Climate Protection Switzerland) in order to fight for ambitious climate action by legally challenging the Swiss government's inadequate climate policies and mitigation measures. The KlimaSeniorinnen filed a legal request with the authorities, claiming that the Swiss authorities are failing to fulfil their duty to protect them as required by the Swiss Constitution and by the European Convention on Human Rights. This article provides a detailed analysis of the KlimaSeniorinnen case within the context of climate litigation worldwide. It argues that the case's human rights arguments, which are grounded in climate science, the United Nations Framework Convention on Climate Change (UNFCCC), the Paris Agreement, environmental principles and international law, are generally transferable to almost any country. Therefore, vulnerable individuals and groups can learn from the KlimaSeniorinnen litigation that there are strong legal grounds to bring human-rights-based climate lawsuits against governments and thus governments should expect more litigation if their climate actions or omissions contravene international law and violate constitutional principles.
Confrontations and concessions: an everyday politics of tourism in three ethnic minority villages, Guizhou Province, China

As a state-promoted livelihood diversification approach for ethnic minority communities in rural China, tourism development influences household and community assets in diverse ways. Focusing on three case study villages in Qiandongnan Hmong and Dong Autonomous Prefecture, Guizhou Province, we compare the livelihoods of one village without tourism to date (but slated for tourism development in the near future), one with a ‘medium’ level of tourism, and another where tourism is in full force. Our analysis of the transitional characteristics of these communities focuses on agriculture, income-related activities, cultural norms, and social relationships to shed light on the everyday politics of ethnic minority households under different stresses and demands from local government and state-controlled tourism businesses. We find that confrontations have arisen due to tourism expansion and state tourism planning directives among a wide range of stakeholders: Zhailao elites, core and peripheral tourism communities, country-level governments, local residents, and tourists. In turn, local residents have made broad concessions ranging from resignation to unwelcome changes in their livelihoods and new income inequalities, to acceptance of certain tourism-based changes and reallocation of resources. In sum, we find that villagers’ everyday politics involves coping with or challenging new tensions in diverse ways, yet at times marginalisation remains.
Understanding the Line Managers’ HRM Role Expectations: Does Size Matter?

Recent years have witnessed burgeoning interest in the line managers’ contribution to HRM effectiveness. This effort requires organizations to consider important contextual conditions to ensure the desired organizational outcomes. This paper explores the significance of the organization size in understanding the line managers’ involvement in HRM activities. Two case studies were conducted, one in a large and another in a small airport involving key members of the airport management who were closely related to the line managers’ HRM role. Content analysis was employed to analyze data from the interviews and written documents. While there were many similarities in the line managers’ HRM role, the differences in the line managers’ HRM role expectations are also found to be related to differences in the size of the organization. More responsibility is expected from line managers in the large airport as compared to the small airport. This finding has important implications in aligning the HRM strategy and organizational outcomes through the line management contribution.
The Patagonian scallop fishing grounds in shelf break frontal areas: the non assessed benthic fraction

In this study, a Picard dredge was used to sample the benthic community in shelf break frontal areas off Argentina in order to detect species that could be sensitive to fishing activities but are not usually caught during the annual monitoring of Patagonian scallop and associated fauna. The present results show at least 62 taxa not reported previously as components of the benthos in the scallop grounds that are potentially subjected to trawling disturbance.
TARANIS XGRE and IDEE detection capability of terrestrial gamma-ray flashes and associated electron beams

Abstract. With a launch expected in 2018, the TARANIS microsatellite is dedicated to the study of transient phenomena observed in association with thunderstorms. On board the spacecraft, XGRE and IDEE are two instruments dedicated to studying terrestrial gamma-ray flashes (TGFs) and associated terrestrial electron beams (TEBs). XGRE can detect electrons (energy range: 1 to 10 MeV) and X- and gamma-rays (energy range: 20 keV to 10 MeV) with a very high counting capability (about 10 million counts per second) and the ability to discriminate one type of particle from another. The IDEE instrument is focused on electrons in the 80 keV to 4 MeV energy range, with the ability to estimate their pitch angles. Monte Carlo simulations of the TARANIS instruments, using a preliminary model of the spacecraft, allow sensitive area estimates for both instruments. This leads to an averaged effective area of 425 cm2 for XGRE, used to detect X- and gamma-rays from TGFs, and the combination of XGRE and IDEE gives an average effective area of 255 cm2 which can be used to detect electrons/positrons from TEBs. We then compare these performances to RHESSI, AGILE and Fermi GBM, using data extracted from literature for the TGF case and with the help of Monte Carlo simulations of their mass models for the TEB case. Combining this data with the help of the MC-PEPTITA Monte Carlo simulations of TGF propagation in the atmosphere, we build a self-consistent model of the TGF and TEB detection rates of RHESSI, AGILE and Fermi. It can then be used to estimate that TARANIS should detect about 200 TGFs yr−1 and 25 TEBs yr−1.
Numerical Simulation of Coronal Waves Interacting with Coronal Holes. II. Dependence on Alfvén Speed Inside the Coronal Hole

We used our newly developed magnetohydrodynamic (MHD) code to perform 2.5D simulations of a fast-mode MHD wave interacting with coronal holes (CHs) of varying Alfvén speed that result from assuming different CH densities. We find that this interaction leads to effects like reflection, transmission, stationary fronts at the CH boundary, and the formation of a density depletion that moves in the opposite direction to the incoming wave. We compare these effects with regard to the different CH densities and present a comprehensive analysis of morphology and kinematics of the associated secondary waves. We find that the density value inside the CH influences the phase speed and the amplitude values of density and magnetic field for all different secondary waves. Moreover, we observe a correlation between the CH density and the peak values of the stationary fronts at the CH boundary. The findings of reflection and transmission on the one hand and the formation of stationary fronts caused by the interaction of MHD waves with CHs on the other hand strongly support the theory that large-scale disturbances in the corona are fast-mode MHD waves.
Hydrothermal Deposits of the Galapagos Rift Zone, Leg 70: Mineralogy and Geochemistry of Major Components

The hydrothermal deposits that we analyzed from Leg 70 are composed of ferruginous green clays and fragments of manganese-hydroxide crust. Data from X-ray diffraction, IR-spectroscopy, electron diffraction, and chemical analyses indicate that the hydrothermal green clays are composed of disordered mixed-layer phases of celadonite-nontronite. Electron diffraction shows that the parameters of the unit cells and the degree of three-dimensional ordering of mixed-layer phases with 80% celadonite interlayers are very close to Fe-micas of polymorphic modification IMceladonite. In some sections, there is a tendency for the number of celadonite layers to increase with depth. The manganese-hydroxide crust fragments are predominantly composed of todorokite (buserite). An essential feature of hydrothermal accumulation is the sharp separation of Fe and Mn. Ba/Ti and Ba/Sr ratios are typical indicators of hydrothermal deposits. Sediments composing the hydrothermal mounds were deposited from moderately heated waters, which had extracted the components from solid basalts in environments where there were considerable gradients of temperature, eH, and pH. The main masses of Fe and Mn were deposited in the late Pleistocene. Postsedimentary alteration of deposited hydrothermal sediments led to their slight recrystallization and, in the green clays, to celadonitization. Further, factor analysis (by Varentsov) of chemical components from these hydrothermal deposits revealed paragenetic assemblages. Green clays corresponding to a definite factor assemblage were formed during the main stage of hydrothermal mineral formation. Manganese hydroxide and associated components were largely accumulated during an early stage and at the end of the main stage.
Fluorescent Silica Nanoparticles in the Detection and Control of the Growth of Pathogen

In this present study the bioconjugated fluorescent silica nanoparticles give an efficient fluorescent-based immunoassay for the detection of pathogen. The synthesized silica nanoparticles were polydispersed and the size of the silica nanoparticles was in the range of 114–164 nm. The energy dispersive X-ray spectrophotometer showed the presence of silica at 1.8 kev and the selected area diffractometer showed amorphous nature of silica nanoparticles. The FTIR spectrum confirmed the attachment of dye and carboxyl group onto the silica nanoparticles surface. The fluorescent silica nanoparticles showed highly efficient fluorescence and the fluorescent emission of silica nanoparticles occurred at 536 nm. The SEM image showed the aggregation of nanoparticles and bacteria. The growth of the pathogenic E. coli was controlled using silica nanoparticles; therefore silica nanoparticles could be used in food packaging material, biomedical material, and so forth. This work provides a rapid, simple, and accurate method for the detection of pathogen using fluorescent-based immunoassay.
Numerical modeling of solar wind influences on the dynamics of the high-latitude upper atmosphere

Abstract. Neutral thermospheric wind patterns at high latitudes obtained from cross-track acceleration measurements of the CHAMP satellite above both polar regions are used to deduce statistical neutral wind vorticity distributions and were analyzed in their dependence on the Interplanetary Magnetic Field (IMF). The average pattern confirms the large duskside anticyclonic vortex seen in the average wind pattern and reveals a positive (cyclonic) vorticity on the dawnside, which is almost equal in magnitude to the duskside negative one. The IMF dependence of the vorticity pattern resembles the characteristic field-aligned current (FAC) and ionospheric plasma drift pattern known from various statistical studies obtained under the same sorting conditions as, e.g., the EDI Cluster statistical drift pattern. There is evidence for hemispheric differences in the average magnitudes of the statistical patterns both for plasma drift and even more for the neutral wind vorticity. The paper aims at a better understanding of the globally interconnected complex plasma physical and electrodynamic processes of Earth's upper atmosphere by means of first-principle numerical modeling using the Upper Atmosphere Model (UAM). The simulations of, e.g., thermospheric neutral wind and mass density at high latitudes are compared with CHAMP observations for varying IMF conditions. They show an immediate response of the upper atmosphere and its high sensitivity to IMF changes in strength and orientation.
Affine structures on complex manifolds

Let M be a complex manifold of complex dimension n and let C={Uiy φt}i^ι be the maximal atlas defining the complex structure on M. A subset ^4 — {t/y, φj}j<Ξjj J^Iy of C is called an affine atlas of M, if <pjir=φj°φ? is a complex affine transformation of C whenever t/yfl Uk^φ. We can define the notion of a maximal affine atlas of M and we say that each maximal affine atlas of M defines a complex affine structure of the complex manifold M. We shall denote by A(M) the totality of complex affine structures on M. The aim of this note is to study the structure of A(M) in the case where M is compact and the complex structure of M is homogeneous and we shall prove the following theorems.
Guided-wave-based damage detection in a composite T-joint using 3D scanning laser Doppler vibrometer

Composite T-joints are commonly used in modern composite airframe, pressure vessels and piping structures, mainly to increase the bending strength of the joint and prevents buckling of plates and shells, and in multi-cell thin-walled structures. Here we report a detailed study on the propagation of guided ultrasonic wave modes in a composite T-joint and their interactions with delamination in the co-cured co-bonded flange. A well designed guiding path is employed wherein the waves undergo a two step mode conversion process, one is due to the web and joint filler on the back face of the flange and the other is due to the delamination edges close to underneath the accessible surface of the flange. A 3D Laser Doppler Vibrometer is used to obtain the three components of surface displacements/velocities of the accessible face of the flange of the T-joint. The waves are launched by a piezo ceramic wafer bonded on to the back surface of the flange. What is novel in the proposed method is that the location of any change in material/geometric properties can be traced by computing a frequency domain power flow along a scan line. The scan line can be chosen over a grid either during scan or during post-processing of the scan data off-line. The proposed technique eliminates the necessity of baseline data and disassembly of structure for structural interrogation.
Organic carbon supply to a large lowland river and implications for aquatic ecosystems

The supply of organic carbon to large river systems is generally poorly understood. At issue are the relative contributions of in-channel, headwater catchment and flood plain primary production and how these contributions vary with flow conditions. Recent work has indicated that fine suspended particulate organic matter (FSPOM) is the most important form of carbon for riverine aquatic food webs. C/N and δ 13 C ratios in samples of FSPOM collected from along a large lowland river system show that during a 1 in 10 year flood catchment soil sources dominate. During non-flood periods the contribution from soil organic matter and C3-riparian vegetation decreases systematically with distance downstream while carbon derived from in-channel primary production increases, dominating (>75%) in the lower reaches. The δ 13 C ratios and radiocarbon dating indicates that the in-channel primary producers are using carbon derived from the breakdown of terrestrial organic matter photosynthesized from the atmosphere 40-50 years ago. These results show that organic matter derived from catchment soils is a major carbon source for large rivers, and reveals the importance of in-channel carbon cycling and primary production.

Some Mathematical Properties of the Dynamically Inconsistent Bellman Equation: A Note on the Two-sided Altruism Dynamics

This article describes some dynamic aspects on dynastic utility incorporating two-sided altruism with an OLG setting. We analyzed the special case where the weights of two-sided altruism are dynamically inconsistent. The Bellman equation for two-sided altruism proves to be reduced to one-sided dynamic problem, but the effective discount factor is different only in the current generation. We show that a contraction mapping result of value function cannot be achieved in general, and that there can locally exist an infinite number of self-consistent policy functions with distinct steady states (indeterminacy of self-consistent policy functions).
