Impact of oscillations of photons into axion-like particles on the very-high energy γ-ray spectrum of the blazar PKS 1424+240

Very high energy (VHE) gamma-rays undergo pair production with low energy photons of background radiation fields. This leads to an attenuation of the p rimary gamma-ray flux of extragalactic sources in the interaction with the extragalactic backg round light (EBL) which stretches from ultraviolet to far-infrared wavelengths. In the presence of magnetic fields, gamma-rays could oscilla te into hypothetical axion-like particles (ALPs). This might lead to a reduced opacity of the Universe for VHE gamma-rays, as ALPs circumvent pair production. Here, the impact of photon-ALP conversions on the spectrum of PKS 1424+240 is demonstrated. A lower limit on the redshift of this blazar was recently determined to be z > 0.6035, making it the farthest source ever observed at VHE energies. Under the assumption of a specific magnetic field scenario and EBL mo del, photon-ALP couplings are derived that lead to an overall concave intrinsic blazar spe ctrum.
WOMEN’S PARTICIPATION IN THE LABOR MARKET AND ECONOMIC DEVELOPMENT: EVIDENCE FROM ECCAS AND ECOWAS COUNTRIES

This paper examines the relationship between women’s participation in the labor market and economic development in ECCAS and ECOWAS over the period 2006-2015 by using dynamic panel data model. The analysis is run from two different perspectives – on one hand, the relationship is investigated for a sample of 24 countries; and on the other hand – the evidence is disaggregated and the relationship is re-examined with two regional blocs (ECCAS, ECOWAS). The OLS, fixed effects model, instrumental IV and the generalized method of moments (GMM) estimator developed by Arellano and Bond (1991) are employed to evaluate and account for dynamic effects. The main results show that there is a U-shaped relationship between female labor force participation and the economic development for the encompassing 24 countries. The findings are important for ECCAS and ECOWAS countries policy makers to undertake effective policies that can boost female labor force participation and enhance economic growth in their countries.
Comparison of Vegetable Oil-Silicone Oil Interfacial Tension Data from the du NoüyRing and the Spinning Drop Methods

Liquid-liquid interfacial tension is very important in colloid and surface chemistry as it detects the amount of energy required to create a new interface. This makes its measurement very crucial. There are different techniques for measuring it, with the common ones being the du Noüy ring and spinning drop methods. The aim of this work is to compare the low interfacial tension values obtained from the du Noüy ring method with those obtained using the spinning drop method in vegetable oil-silicone oil systems. Low interfacial tension values of various vegetable oil-silicone oil systems were measured with the du Noüy ring and spinning drop methods. The interfacial tension values range from 2.1 to 2.8 mN m‒1 for the du Noüy ring method and 1.0 to 2.7 mN m‒1 for the spinning drop method. These values agree closely)05.0(=p. This shows that both methods can be used for measuring interfacial tension with high accuracy in vegetable oil-silicone oil systems.
ECONOMIC GROWTH AND EMPLOYMENT IN AGRICULTURAL SECTOR ON POVERTY IN ACEH PROVINCE

This empirical study aims to analyze the impact of economic growth and employment in the agricultural sector on poverty in Aceh Province. The study is conducted on annual time series data for the period of 1995-2017 while to explain the research objectives used Autoregressive Distributed Lag (ARDL) model and Granger Causality. The results found, in the short term, only employment in the agricultural sector has a significant effect on poverty. Meanwhile, in the long term, economic growth has a profound and negative impact on poverty. On the contrary, the absorption of labor in the agricultural sector tends to increase poverty. In addition, the results obtained that economic growth has a unidirectional relationship with employment in the agricultural sector. It was, therefore, suggested that the government should prioritize economic development in regions that have relatively high poverty rate and build an agro-industry in Aceh to increase agricultural value added and also absorb more labor so it can enable to reduce the poverty rate.

Microsatellites for the Amazonian Fish Hypophthalmus marginatus

We isolated 41 and characterized 17 microsatellite loci for evaluating the genetic structure of the Amazonian fish Hypophthalmus marginatus, from the Tocantins and Araguaia River in the Eastern Amazonia. Of the 17 selected microsatellite sequences, 15 were dinucleotide repeats, 9 of which were perfect (5–31 repetitions) and 6 were composite motifs. Among these 17 microsatellites, only two were polymorphic. The average number of alleles (Na) observed in the five examined populations ranged from 3.5 to 4.5, while the average observed heterozygosity (Ho) ranged from 0.3 to 0.6. The allelic frequency was less homogeneous at the locus Hm 5 than that for the Hm 13. Genetic diversity was measured in three upstream and two downstream populations under the influence of the Tucurui Hydroelectric Dam. Our findings provide evidence for low levels of genetic diversity in H. marginatus of the Tocantis basin possibility related to the Dam construction. The Fst and Rst analysis fits well with migratory characteristics of H. marginatus, suggesting the existence of a gene flow mainly in the upstream or downstream directions. To test the hypothesis that the Dam was responsible for the detected reduction on this species genetic diversity, a large number of genetic markers are recommended, covering geographic distribution range of the fish species.

Dependency graph-based statistical machine translation

Statistical Machine Translation has been shown to beneﬁt from complex linguistic structures. However, previous work mainly focuses on sequences and trees. In this thesis, we build dependency graphs which are constructed from dependency trees and uniformly represent both dependency relations and sequential relations, including bigram relations and sibling relations. We propose translation models to translate these graphs into target strings and conduct experiments on Chinese--English and German--English translation tasks. As a motivation, we ﬁrstly present a pseudo forest-to-string model which improves a dependency tree-to-string model by dependency decomposition. The decomposition takes sibling relations into consideration which results in more rules being used and thus a higher phrase coverage. Experiments show that such decomposition is beneﬁcial to translation performance. Integrating phrasal rules further improves our model. Then, we propose a segmentational graph-based translation model. It segments graphs into subgraphs and generates translations from left to right by combining translations of these subgraphs. The graphs explicitly combine dependency relations and bigram relations. In experiments, the graph-based model outperforms both the phrase-based model and treelet-based model. In addition, we improve this model by using a graph segmentation model to take source context into consideration. Furthermore, inspired by using tree grammars to translate trees, we propose recursive graph-based translation models by using graph grammars. An edge replacement grammar is used to translate dependency-edge graphs which are converted from dependency trees by labeling edges to naturally take sibling relations into consideration. A node replacement grammar is used to translate dependency-sibling graphs which explicitly add sibling links to dependency trees. Experiments show that our models are signiﬁcantly better than the hierarchical phrase-based model.
Patterns of Neighboring and Predictors of Neighboring across Race: A Latent Class Analysis

ABSTRACT Residential segregation has created a stark racial and economic divide in the United States. Prior research suggests facilitating social interactions among diverse groups of neighbors is a particularly difficult – and particularly important step in addressing the legacy of segregation in the United States. This study examines patterns of neighboring across race using latent class analysis, and identifies individual characteristics associated with frequent neighboring interactions across race. We found three distinct patterns of neighboring: reluctant neighboring across race, limited neighboring across race, and actively neighboring across race. Our findings highlight the complexity of studying neighboring – particularly neighboring across race, and demonstrate that neighboring typologies warrants future research as it relates to why an individual exhibits a particular pattern of neighboring across race.
North-South Trade; Is Africa Unusual?

We estimate a gravity model to address the question of whether Africa’s bilateral trade with industrial countries is “unusual” compared with other developing country regions. Our main finding is that the unusually low level of African trade is explained by economic size, geographical distance, and population. This result holds after controlling for a country’s access to the sea, composition of exports, linguistic ties with industrial countries, and trade policies. If anything, the average African country tends to “overtrade” compared with developing countries in other regions, although the degree to which Africa overtrades has steadily declined over the past two-and-one-half decades.
Is Equity Market Efficient? Evidence from a Small Open Economy

This study investigates relationships between macroeconomic variables and stock market over the period of 1987Q1-2012Q1 for Turkey. The study is conducted by evaluating 2001 crisis, the most severe crisis in the history of Turkey which caused a cyclical shift, which has not been in consideration by the previous literature. This study used Toda and Yamamoto (1995) method to uncover those relationships. Here, those investigations provide information on whether Turkish stock market is efficient or not and whether the stock market can be used as a leading indicator for one or more fundamental macroeconomic variables. The results indicated that 2001 crisis had statistically significant impact on the stock market and Turkish economy. Before 2001 crisis, the stock market was not efficient but after 2001 crisis the stock market became efficient. The stock market was also found as a leading indicator for the real economic activity that is consistent with the literature findings on Turkey.
Have Community Policing Initiatives Changed Police Perceptions of Accountability in Macquarie Fields and have they Led to Better Police-Community Relations?

In February 2005, riots involving local youth against police erupted in Macquarie Fields following the deaths of two local young men who were in a stolen vehicle being pursued by police. The riots at the time were dismissed by the serving Government, the Opposition, NSWP police management and sections of the media, as merely a handful of young thugs behaving poorly. However, subsequent media coverage, political debate recorded in Hansard, academic literature and the findings of the Standing Committee on Social Issues (2006) revealed discontent amongst some residents concerning the behavior, attitudes and inconsistent actions of Macquarie Fields police. This study, through interviews conducted with government and non-government service providers servicing the Macquarie Fields community and interviews/observations conducted with Macquarie Fields police participants, examined perceptions held by Macquarie Fields police concerning their accountability and partnership with the community. It sought to discover whether police-community programs implemented following the 2005 riots impacted upon police perceptions of accountability to the community and led to improved relations between police and community. Findings indicated that despite the attempts of Government and police management to improve relations between Macquarie Fields police and community, the relationship remained problematic. Police participants were found to hold variable notions of accountability and partnership towards the community. This combined negatively with the primary crime reduction strategy of ‘stopping searching and moving on’ local youth socializing in public places, which was reported by community service respondents as being conducted by younger inexperienced police in an adversarial manner.
Performance Measurement of Active Investment Strategies Using Pure Factor Portfolios

The article uses pure factor portfolios formed by multivariate cross-sectional regressions to examine whether these active investment strategies could achieve excess return relative to passive strategies. The hypothesis can also be construed as a test of market efficiency. The study includes ten style factors. Our empirical study shows that a consensus buy strategy of the pure value factor yielded significant positive excess returns in the past almost 20 years. Size and momentum factors characterised in the literature by positive excess return are not significant in our study. Excess return of the factors capturing riskiness (earnings variability, volatility, leverage) is significant and negative, which corroborates with our expectations, rendering a consensus sell investment strategy successful, based on these factors. The profitability, growth and trading activity factors produced results contrary to our expectations; therefore, excess return could have been achieved via a contrarian selling strategy. Our research results are consistent with the weak form of market efficiency analyses.
The Role of Loneliness in the Relationship between Anxiety and Depression in Clinical and School-Based Youth.

Identifying mechanisms that explain the relationship between anxiety and depression are needed. The Tripartite Model is one model that has been proposed to help explain the association between these two problems, positing a shared component called negative affect. The objective of the present study was to examine the role of loneliness in relation to anxiety and depression. A total of 10,891 school-based youth (Grades 2–12) and 254 clinical children and adolescents receiving residential treatment (Grades 2–12) completed measures of loneliness, anxiety, depression, and negative affect. The relationships among loneliness, anxiety, depression, and negative affect were examined, including whether loneliness was a significant intervening variable. Various mediational tests converged showing that loneliness was a significant mediator in the relationship between anxiety and depression. This effect was found across children (Grades 2–6) and adolescent (Grades 7–12) school-based youth. In the clinical sample, loneliness was found to be a significant mediator between anxiety and depression, even after introducing negative affect based on the Tripartite Model. Results supported loneliness as a significant risk factor in youths' lives that may result from anxiety and place youth at risk for subsequent depression. Implications related to intervention and prevention in school settings are also discussed.
THE EFFECT OF MONOPOLY POWER AND INTEGRITY ON THE TENDENCY TO COMMIT FRAUD IN E-PROCUREMENT

The main objective of this study is to examine the influence of Monopoly Power and Integrity on fraud that occurs in the e-procurement process. This study involved parties directly related to the procurement of goods and services and the development of electronic procurement systems incorporated in the Procurement Service Unit (referred to in Indonesia as Unit Layanan Pengadaan / ULP) and the Electronic Procurement Services (or referred to Layanan Pengadaan Secara Elektronik / LPSE). This study used a quantitative approach and primary data in the form of questionnaire as measurement instrument. The method of analysis was done using SmartPLS 3. Path analysis and bootstrapping technique were used to test the hypothesis. The results of this study show that power monopoly has a significant positive effect on fraud in e-procurement, while integrity has a significant negative effect on fraud in e-procurement.
Influence of Students’ Interactions Abroad on Developing Intercultural Competence

ABSTRACT Study-abroad programs represent one of the initiatives implemented by universities to internationalize curricula and prepare students to perform in a globalized society. The purpose of this research was to evaluate how intercultural interactions influence the development of intercultural competence. Results from a sample of 158 students indicate that students’ intercultural contacts have a significant positive effect on their change in intercultural competence, which is calculated as the difference between the measures before and after going abroad (b = .236; s.e. = .104; β = .289; p < .05). These findings confirm that mere exposure to foreign environments does not automatically result in effective learning; thus, universities should set conditions to facilitate active engagement between visiting students and national hosts.
