description: Voltage-induced ferromagnetic resonance (V-FMR) in magnetic tunnel junctions (MTJs) with a W buffer is investigated. Perpendicular magnetic anisotropy (PMA) energy is controlled by both thickness of a CoFeB free layer deposited directly on the W buffer and a post-annealing process at different temperatures. The PMA energy as well as the magnetization damping are determined by analysing field-dependent FMR signals in different field geometries. An optimized MTJ structure enabled excitation of V-FMR at frequencies exceeding 30 GHz. The macrospin modelling is used to analyse the field- and angular-dependence of the V-FMR signal and to support experimental magnetization damping extraction.

description: The case-study overviews the possible reduction for the methane gas emission in order to avoid of the more global warming effects and climate change caused by the human activity at latest decades. To collect international data base is for analysing and valuing methane gas emission based on the different country-groups, emphasizing responsibility of developing countries and highly developed countries for gas emission, also the methane emission based is on the economic sectors. China and India have share 8% of China and 2% of India respectively of cumulative CO2 emissions over the period 1900-2005, the US and the EU are responsible for more than half of emissions. Based on the estimation the global gas emissions of methane in the whole world has increased by 37% for period of 1990- 2030, as four decades, and this was 0,92% annual rate growth, while the OECD has increased the methane emission by 8,5% for this period, which means 0,21% growth rate annually. Scenario in developing countries for 2013-2020 the methane gas emission reduction could have been 8200 Mt of CO2e (Equivalent) and less than 10 US dollar per ton in more cost financing. Highly developed and developing economies (last one their methane emission share 56% in 1990, estimated 66,8% in 2030) increase their economic growth by mostly fossil energy resulted in increasing also methane gas emissions. The methane gas emission can be solved by those results-based-finance forms relevant to Kyoto Protocol, which can extend in the world by financial institutions.

description: We apply the quasiparticle self-consistent GW method (QSGW) to slab models of ionic materials, LiF, KF, NaCl, MgO, and CaO, under electric field. Then we obtain the optical dielectric constants E(Slab) from the differences of the slopes of the electrostatic potential in the bulk and vacuum regions. Calculated E(Slab) show very good agreements with experiments. For example, we have E(Slab)=2.91 for MgO, in agreement with the experimental value E(Experiment)=2.96. This is in contrast to E(RPA)=2.37, which is calculated in the random-phase approximation for the bulk MgO in QSGW. After we explain the difference between the quasiparticle-based perturbation theory and the Greens function based perturbation theory, we interpret the large difference E(Slab)-E(RPA)=2.91-2.37 as the contribution from the vertex correction of the proper polarization which determines the screened Coulomb interaction W. Our result encourages the theoretical development of self-consistent G0W approximation along the line of QSGW self-consistency, as was performed by Shishkin, Marsman and Kresse [Phys. Rev. Lett. 99, 246403(2007)].

description: Maltodextrin and citric acid are two types of natural materials with the potential as an eco-friendly binder. Maltodextrin is a natural substance rich in hydroxyl groups and can form hydrogen bonds with lignoselulosic
material, while citric acid is a polycarboxylic acid which can form an ester bond with a hydroxyl group at lignoselulosic material. The combination of maltodextrin and citric acid as a natural binder materials supposed
to be increase the ester bonds formed within the particleboard. This research determined to investigate the bonding properties of a new adhesive composed of maltodextrin/citric acid for nipa frond particleboard. Maltodextrin and citric acid were dissolved in distillated water at the ratios of 100/0, 87.5/12.5, 75/25 and 0/100, and the concentration of the solution was adjusted to 50% for maltodextrin and 60% citric acid (wt%). This adhesive solution was sprayed onto the particles at 20% resin content based on the weight of oven dried particles. Particleboards with a size of 25 × 25 × 1 cm, a target density 800 kg/m3 were prepared by hot-pressing at press temperatures of 180 degrees or 200 degrees, a press time of 10 minute and board pressure 3.6 MPa. Physical and mechanical properties of particleboard were tested by a standard method (JIS A 5908). The results showed that added citric acid level in maltodextrin/citric acid composition and hot-pressing temperature had affected to the properties of particleboard. The optimum properties of the board were achieved at a pressing temperature of 180 degrees and the addition of only 20% citric acid. The results also indicated that the peak intensity of C=O group increased and OH group decreased with the addition of citric acid and an increase in the pressing temperature, suggesting an interreaction between the hydroxyl groups from the lignocellulosic materials and carboxyl groups from citric acid to form the ester groups.

description: Advancing the domestic industrial production towards a sustainable, resource-preserving direction can become an important pillar to support competitiveness in the European Union, as well as in Hungary. Reaching the de-carbonization goals for industrial production via lowering the production volume may result in less desirable macro-economic effects, so decisions which concern the industry require a lot of attention from the climate policy as well. In the case of the cement sector, economic actors have to be motivated to make energy-efficiency investments and technology developments, which also show promise in terms of business efficiency. In the more natural-resource-intensive branches of the industry, both innovations and technological developments will be required to reduce the amount of used non-renewable energy resources, keep it in the industrial cycle, and reduce environmental load. The importance of greener cement will be essential in the near future to reduce the sector’s CO2 emission levels. We need to identify more sector branches which relate to sustainability, which can aid the country in establishing long-term competitiveness that points towards the de-carbonization goals. The cost-efficiency aspects of this development process are the most tedious questions in today’s business planning.

description: Dark matter constitutes 85% of the matter in our Universe. However, detecting dark matter experimentally is exceedingly difficult, with the XENON1T dark matter detector being the most sensitive measurement to date. These difficulties arise from trying to measure extremely low energies and perform regressions with a poor signal-to-noise ratio. Previous attempts tried to solve this with convolution neural networks, but experienced problems due to the structure of experimental physics data (non-square lattices). We present the first application of graph convolutional neural networks (GCNN) to this regression problem in our dark-matter field. Beyond having a more natural architecture design, we attempt to include physical constraints such as: all results from the regression occurring within the bounds of the experiment and being uniform. As another goal, we place the requirement that only 1 part per 10 million of the regression results are more than 1 cm off from the target. Our prototype GCNN was built with two graph convolution layers, a final fully connected layer, and a mean squared error cost function. This prototype was able to produce below 3 mm root mean squared error in both the x and y dimensions, where the spacing between light sensors is 7 cm. XENONnT will provide the perfect test case for these methods as it is already collecting data, with the promise of extending this test case to other areas of particle physics.

description: Black rice bran has a number of health benefits and it contains a phytochemical that is associated with a decreased cancer risk. This research aimed to examine the ability of ethanolic extract fractions of ‘Woja Laka’ black rice bran to prevent the growth of liver carcinoma HepG2 cells. Ethanolic extracts of ‘Woja Laka’ and ‘IR 64’ (white rice) bran were fractionated by preparative thin layer chromatography. The cytotoxic activities of the fractions were conducted on HepG2 cell lines by using the MTT assay. When the IC50 value of the fraction showed lower than 500 μg/ml, it was tested for anti-proliferation using the doubling time method. Apoptotic induction and cell cycle arrest were measured by a flow cytometry method. The selectivity cells respon was performed on Vero cells. Result of this study showed that six fractions (F) of F1, F2, F3, F4, F5 and F6 from the ‘Woja Laka’ and three fractions of F1, F2 and F3 from the ‘IR 64’ were examined for their preventive activities on HepG2 cells. The selected fractions F3 and F6 from ‘Woja Laka’ showed highly cytotoxic activity (184.35 ± 16.81 and 283.64 ± 58.13 μg/ml respectively) on HepG2 cells. Furthermore, the fractions of the white rice bran extract showed IC50 > 500 μg/ml. We found that the fractions F3 and F6 from ‘Woja Laka’ were able to inhibit cell proliferation, induce apoptosis and cause G0/G1-phase arrest in the HepG2 cells, while the Vero cells were less responsive to these fractions (IC50 > 470 μg/ml). These results suggest that the compounds found in fractions F3 and F6 of the ethanolic extract of ‘Woja Laka’ black rice bran inhibit the growth of liver carcinoma HepG2 cells.

description: Novel application of a Graph Neural Network for event localization in the XENON1T dark matter direct detection time projection chamber. Our graph neural network made use of the signals produced by events in XENON1T to reconstruct the positions of said events. This is an early application of a graph neural network in particle physics and for regression problems. We have shown that such a neural network is competitive with the state-of-the-art for this type of problem.

Motor milestones

description: Abstract: Objectives: Motor difficulties are often reported in individuals with attention deficit hyperactivity disorder (ADHD). The aims of this study are to detail the motor profile of children with ADHD and to determine whether the motor impairment present in a large proportion of children with ADHD represents a phenotypic characteristic of ADHD or a co-occurring deficit. Methods: Participants with ADHD (N = 51; age 8 to 15 years) and typically developing (TD) motor matched control children (N = 75; age 4 to 11 years) completed the largest battery of assessments of motor function that have been used with this population to date, as well as a measure of inhibition as a behavioural measure of ADHD characteristics. Parents/caregivers also completed questionnaires relating to ADHD symptomology and a retrospective report of their child’s motor milestone achievement. Results: A motor deficit was observed in 47% of our ADHD sample. Few relationships were observed between ADHD core characteristics and motor competence. Furthermore, there was an uneven profile of motor performance across different motor tasks, relative to the TD children. Interestingly, it appears that motor milestone achievement is not delayed in ADHD. Conclusions: Our findings suggest that the motor deficit observed in ADHD is not inherent to ADHD. The motor deficit observed in some children with ADHD does not represent a simple delay in development and is not observed in infancy with respect to reaching motor milestones.

description: Abstract: The maintenance of cooperative behavior is fundamental for the prosperity of human societies. Empirical studies show that high cooperation is frequently associated with the presence of strong social ties, but they are silent on whether a causal mechanism exists, how it operates, and what features of the social environment are conducive to its emergence. Here we show experimentally that strong ties increase cooperation and welfare by enabling the emergence of a close-knit and strongly bound cooperative elite. Crucially, this cooperative elite is more prevalent in social environments characterized by a large payoff difference between weak and strong ties, and no gradation in the process of strengthening a tie. These features allow cooperative individuals to adopt an all or nothing strategy to tie strengthening based on the well-known mechanism of direct reciprocity: participants become very selective by forming strong ties only with other cooperative individuals and severing ties with everyone else. Once formed, these strong ties are persistent and enhance cooperation. A dichotomous society emerges with cooperators prospering in a close-knit, strongly bound elite, and defectors earning low payoffs in a weakly connected periphery. Methodologically, our set-up provides a framework to investigate the role of the strength of ties in an experimental setting.

description: Increasingly, empirical evidences are substantiating the effects of climate change on agricultural production is a reality. In the early part of the 20th century many were skeptical about the so-called climate change that is due to global warming. The Intergovernmental Panel on Climate Change (IPCC, 2007) defines climate change as follows: “climate change refers to a change in the state of the climate that can be identified by changes in the mean or variability of its properties and that persists for extended periods, typically decades or longer” This study analyses the impact of climate change on cereals production (millet and maize) in the Gambia using a time series data for a period of 46 years (1960 – 2013) at an aggregate level to assess the relationship between climate (temperatures and rainfall,) and non-climate variables fertilizer, area planted respectively and yield. The specific objectives of the research are: (1) How climate change affects the expected cereals (Millet and Maize) output or yield in the Gambia. (2) How the level of output risk within cereals (Millet and Maize) farming is affected? In order to achieve these set objectives, the paper will adopt Just and Pope modified Ricardian production functions for climate change impact assessments (e.g., Chen et al. 2004), the paper will also control for the impacts of regular input factors in the production process. The study used a data set for the Gambia comprising variables relevant for cereals production and climate information from 1960 through 2013. There is strong evidence that climate will affects Maize and Millet; according to the analysis 77% and 44% of the variability in the yield of Maize and Millet respectively is explained by the climate and non-climate variables included in the model. Given the effects of climate variables on cereals production, and increasing climate change vulnerabilities on other food production section, the result of this paper will add voice to the growing call for policy makers to step up funding in research and development in climate change adaptation and mitigation.

description: Fickian yet non-Gaussian diffusion is observed in several biological and soft matter systems, yet the underlying mechanisms behind the emergence of non-Gaussianity while retaining a linear mean square displacement remain speculative. Here, we characterize quantitatively the effect of spatial heterogeneities on the appearance of non-Gaussianity in Fickian diffusion. We study the diffusion of fluorescent colloidal particles in a matrix of micropillars having a range of structural configurations: from completely ordered to completely random. We show that non-Gaussianity emerges as a direct consequence of two coupled factors; individual particle diffusivities become spatially dependent in a heterogeneous randomly structured environment, and the spatial distribution of the particles varies significantly in such environments, further influencing the diffusivity of a single particle. The coupled mechanisms lead to a considerable non-Gaussian nature even due to weak disorder in the arrangement of the micropillars. A simple mathematical model validates our hypothesis that non-Gaussian yet Fickian diffusion in our system arises from the superstatistical behavior of the ensemble in a structurally heterogeneous environment. The two mechanisms identified here are relevant for many systems of crowded heterogeneous environments where non-Gaussian diffusion is frequently observed, for example in biological systems, polymers, gels and porous materials.

description: Trimodal grain structure was effective to balance the strength-ductility trade-off in ultrafine-grained metals, but the relationship between microstructures and mechanical performance is unclear. Here the dimension of coarse grain (CG) domains was elaborately tuned in the trimodal CNT/2024Al composites, and an excellent strength-ductility combination (Tensile strength: 716 ± 5 MPa, Elongation: 9.1 ± 0.3%) was achieved by optimizing the CG bands (∼4.4 µm in width). We found that the size of CG bands hardly affected strain hardening rate, but caused different crack-blunting behaviors, which was responsible for the superior strength-ductility synergy. This work highlights the importance of CG domains design in heterostructured materials. Trimodal grain structured CNT/2024Al composites with different coarse-grained (CG) bands The dimensions of coarse-grained domains were elaborately tuned in heterostructured materials, and an excellent strength-ductility combination was achieved by blunting cracks.

description: While extracting a subset of a commit history, specifying the necessary portion is a time-consuming task for developers. Several commit-based history slicing techniques have been proposed to identify dependencies between commits and to extract a related set of commits using a specific commit as a slicing criterion. However, the resulting subset of commits become large if commits for systematic edits whose changes do not depend on each other exist. We empirically investigated the impact of systematic edits on history slicing. In this study, commits in which systematic edits were detected are split between each file so that unnecessary dependencies between commits are eliminated. In several histories of open source systems, the size of history slices was reduced by 13.3-57.2% on average after splitting the commits for systematic edits.

description: Abstract: Soluble aggregates of amyloid-β (Aβ) have been associated with neuronal and synaptic loss in Alzheimer’s disease (AD). However, despite significant recent progress, the mechanisms by which these aggregated species contribute to disease progression are not fully determined. As the analysis of human cerebrospinal fluid (CSF) provides an accessible window into the molecular changes associated with the disease progression, we characterised soluble aggregates present in CSF samples from individuals with AD, mild cognitive impairment (MCI) and healthy controls using a range of sensitive biophysical methods. We used super-resolution imaging and atomic force microscopy to characterise the size and structure of the aggregates present in CSF and correlate this with their ability to permeabilise lipid membranes and induce an inflammatory response. We found that these aggregates are extremely heterogeneous and exist in a range of sizes, varying both structurally and in their mechanisms of toxicity during the disease progression. A higher proportion of small aggregates of Aβ that can cause membrane permeabilization are found in MCI CSF; in established AD, a higher proportion of the aggregates were larger and more prone to elicit a pro-inflammatory response in glial cells, while there was no detectable change in aggregate concentration. These results show that large aggregates, some longer than 100 nm, are present in the CSF of AD patients and suggest that different neurotoxic mechanisms are prevalent at different stages of AD.

description: Abstract: Introduction: Blood-based sample collection is a challenge, and dried blood spots (DBS) represent an attractive alternative. However, for DBSs to be an alternative to venous blood it is important that these samples are able to deliver comparable associations with clinical outcomes. To explore this we looked to see if lipid profile data could be used to predict the concentration of triglyceride, HDL, LDL and total cholesterol in DBSs using markers identified in plasma. Objectives: To determine if DBSs can be used as an alternative to venous blood in both research and clinical settings, and to determine if machine learning could predict ‘clinical lipid’ concentration from lipid profile data. Methods: Lipid profiles were generated from plasma (n = 777) and DBS (n = 835) samples. Random forest was applied to identify and validate panels of lipid markers in plasma, which were translated into the DBS cohort to provide robust measures of the four ‘clinical lipids’. Results: In plasma samples panels of lipid markers were identified that could predict the concentration of the ‘clinical lipids’ with correlations between estimated and measured triglyceride, HDL, LDL and total cholesterol of 0.920, 0.743, 0.580 and 0.424 respectively. When translated into DBS samples, correlations of 0.836, 0.591, 0.561 and 0.569 were achieved for triglyceride, HDL, LDL and total cholesterol. Conclusion: DBSs represent an alternative to venous blood, however further work is required to improve the combined lipidomics and machine learning approach to develop it for use in health monitoring.

description: Abstract This study is to measure competitiveness and its effect on the quantity of Saudi exports of dates in the international market between 1990- 2011. In order to measure the competitiveness of date exports, the study depended on a number of indexes such as the revealed comparative advantage and the competitive advantage. The study also depended on the analysis of simple regression to study the relationship between the Saudi exports of dates and the competitiveness indexes during the study period. This study showed that the United Arab Emirates (UAE) is the main market for Saudi exports of dates, as it imported about 61.2%, followed by the United Kingdom (UK) at 12.8%, then Syria, Jordan, Kuwait, Sri Lanka, and Qatar at 3.8%, 1.5%, 1.4%, 1.1% and 1.1%, respectively between 2000 and 2011. The average of the revealed comparative advantage and the competitive advantage for Saudi exports of dates is 49.27 and 55.25 respectively. The Kingdom of Saudi Arabia is distinguished with the revealed comparative advantage and the competitive advantage for date exports between 1990 and 2011. The study showed that there is an increase by 10% in the competitive advantage for the exports of Saudi dates, resulting in an increase in Saudi exports of the same good by 10.37%. The study recommends the importance of increasing the competitiveness of Saudi exports of dates in the international market through technological advances used in packaging and storage. Additionally, the study recommends creating a new market for Saudi exports of dates by assigning commercial representation to prepare studies of external demands on date exports, and provide information about foreign consumer tastes to exporters. Commercial representation will also provide Saudi Arabia information about the quantity and type of dates that foreign consumers need, as well as the export prices of competitive countries in the international market. Keywords: dates, competitiveness, exports, international market.

Multiple testing problems

description: Abstract: It is quite common that the structure of a time series changes abruptly. Identifying these change points and describing the model structure in the segments between these change points is of interest. In this paper, time series data is modelled assuming each segment is an autoregressive time series with possibly different autoregressive parameters. This is achieved using two main steps. The first step is to use a likelihood ratio scan based estimation technique to identify these potential change points to segment the time series. Once these potential change points are identified, modified parametric spectral discrimination tests are used to validate the proposed segments. A numerical study is conducted to demonstrate the performance of the proposed method across various scenarios and compared against other contemporary techniques.

description: A specificity method to detect mice meat contamination in beef meatballs using specific primer-polymerase chain reaction (PCR) technique has been developed. The primer ND1-P1 primers were designed using primer-BLAST software using mtDNA of mice as a template. The Primer ND1-P1 forward (5’-CGGCATCCTACAACCATTTGC-3’) and reverse (5’-CGGCTCGTAAAGC-TCCGAA-3’) was able to amplify a 294 bp fragment of ND1 gene in mice mtDNA. The primers have been proven precise with only amplify the target fragment in mice meatball but not in another meatball including beef meatball, chicken meatball, pork meatball, horse meatball, and goat meatball. The present of mice meat in meatballs can be detected at a concentration as low as 5% (w/w). The ND1-P1 primer is potentially used as a specific marker for detection of mice meat in the meat products.

description: We examine the analytic properties of the photon polarization function in a background magnetic field, using the technique of inverse Mellin transform. The photon polarization function is first expressed as a power series of the photon energy $ω$ with $ω< 2m_e$. Based upon this energy expansion and the branch cut of the photon polarization function in the complex $ω$ plane, we compute the absorptive part of the polarization function with the inverse Mellin transform. Our results are valid for arbitrary photon energies and magnetic-field strengths. The applications of our approach are briefly discussed.

description: We study behaviour of ionized region of a Keplerian disk orbiting a Schwarzschild black hole immersed in an asymptotically uniform magnetic field. In dependence on the magnetic parameter ${\cal B}$, and inclination angle $θ$ of the disk plane with respect to the magnetic field direction, the charged particles of the ionized disk can enter three regimes: a) regular oscillatory motion, b) destruction due to capture by the magnetized black hole, c) chaotic regime of the motion. In order to study transition between the regular and chaotic type of the charged particle motion, we generate time series of the solution of equations of motion under various conditions, and study them by non-linear (box counting, correlation dimension, Lyapunov exponent, recurrence analysis, machine learning) methods of chaos determination. We demonstrate that the machine learning method appears to be the most efficient in determining the chaotic region of the $θ-r$ space. We show that the chaotic character of the ionized particle motion increases with the inclination angle. For the inclination angles $θ\sim 0$ whole the ionized internal part of the Keplerian disk is captured by the black hole.

description: The Pseudomonas genus includes many species living in diverse environments and hosts. It is important to understand which are the major evolutionary groups and what are the genomic/proteomic components they have in common or are unique. Towards this goal, we analyzed 494 complete Pseudomonas proteomes and identified 297 core-orthologues. The subsequent phylogenomic analysis revealed two well-defined species (Pseudomonas aeruginosa and Pseudomonas chlororaphis) and four wider phylogenetic groups (Pseudomonas fluorescens, Pseudomonas stutzeri, Pseudomonas syringae, Pseudomonas putida) with a sufficient number of proteomes. As expected, the genus-level core proteome was highly enriched for proteins involved in metabolism, translation, and transcription. In addition, between 39−70% of the core proteins in each group had a significant presence in each of all the other groups. Group-specific core proteins were also identified, with P. aeruginosa having the highest number of these and P. fluorescens having none. We identified several P. aeruginosa-specific core proteins (such as CntL, CntM, PlcB, Acp1, MucE, SrfA, Tse1, Tsi2, Tse3, and EsrC) that are known to play an important role in its pathogenicity. Finally, a holin family bacteriocin and a mitomycin-like biosynthetic protein were found to be core-specific for P. cholororaphis and we hypothesize that these proteins may confer a competitive advantage against other root-colonizers.

description: The sugarcane aphid (SCA) has become the most important pest in sorghum since its detection in 2013. Due to its rapid population growth, great dispersion capacity, and reduced availability of effective insecticides this aphid is capable of causing substantial damage to sorghum production. Little work has been conducted to assess and better understand the economic impact caused by the SCA infestation. The objective of this study was to quantify the economic impact of SCA on sorghum growers in the Lower Rio Grande Valley (LRGV), Texas, where 11.5% of the state production is located. Forty-one local producers were surveyed resulting in a representative sample of 46,578 acres in 2014 and 49,761 acres in 2015. The questionnaire gathers detailed information about yearly crop yields, crop acreage, insecticide application decisions, and management and production practices. Collected data were used to estimate the change in profit associated to the SCA outbreak. Empirical results indicate that the SCA reduced profit by $64.29/acre in 2014 and by $36.17/acre in 2015. At the regional level, the SCA has caused a total economic loss to farmers in the LRGV of about $31.60M.

description: The study was conducted to investigate the concentrations, distributions, sources, and potential ecological risk of heavy metals in surface sediments from the Old Brahmaputra River. Sediment samples were collected from five sampling stations and analyzed with an inductively coupled plasma mass spectrometer (ICP-MS). The results showed that mean concentrations (mg/kg) of heavy metals were in order of Ni (58.82) > Cr (32.45) > Pb (21.04) > Cu (14.24) > Cd (3.81) > As (2.02). Element-specific environmental indices exposed that the ecological risks trailed in the same downward direction as Cd > Ni > Pb > As > Cu > Cr. The contamination factor (CF), enrichment factor (EF), and geo-accumulation index (Igeo) exposed all cases to a modest level of contamination except for Cd, which has a significant level of contamination. Only Ni and Cd were found to pose a high ecological risk for aquatic life based on the sediment quality guidelines. The prospective ecological risk factor and potential ecological risk both suggested low to moderate ecological risk. The river sediments were mostly uncontaminated or mildly contaminated, posing a minimal ecological risk. The study concluded that the Old Brahmaputra River is subjected to anthropogenic disturbances in its aquatic environment.

description: We apply the GLV Reaction Operator formalism to compute the effects of multiple elastic scatterings of jets propagating through dense matter. We derive the elastic Reaction Operator and demonstrate that the recursion relations have a closed form solution that reduces to the familiar Glauber form. We also investigate the accuracy of the Gaussian dipole approximation for jet transverse momentum broadening.

Affective Reactions Among Students Belonging to Ethnic Groups Engaged in Prior Conflict

Subjects: subject: 170113 Social and Community Psychology

description: The study aimed at investigating any bias in the perceptions of young people from two ethnic groups who were not directly involved in an ethnic conflict. Assuming that such perception bias only happens in the members of ethnic groups who were involved in the conflict and in those who became the victims of the other group’s transgression. Therefore, we predicted that the subjects from the Dayaknese group would evaluate the photos of their own group members more positively compared to their perception of the Madurese photos. Meanwhile, there would be no bias among Madurese students in evaluating both Dayak and Madura photos. An experimental approach was carried out using photos of neutral faces of Dayaknese and Madurese people. Each photo was presented with negative or positive words. The participants of the study comprised 111 students who represented Madurese and Dayaknese ethnic groups, as well as Javanese who had not been involved in the conflict serving as the control group. They were asked to evaluate the photos in terms of the negativity and positivity of each picture. A two-way ANOVA supported the hypothesis that the Dayaknese evaluated their own groups better than the other ethnic groups, while the Madurese did not.
