Abstract
Statistical models in medical and population genetics typically assume that individuals assort randomly in a population. While this simplifies model complexity, it contradicts an increasing body of evidence of nonrandom mating in human populations. Specifically, it has been shown that assortative mating is significantly affected by genomic ancestry. In this work, we examine the effects of ancestry-assortative mating on the linkage disequilibrium between local ancestry tracks of individuals in an admixed population. To accomplish this, we develop an extension to the Wright–Fisher model that allows for ancestry-based assortative mating. We show that ancestry-assortment perturbs the distribution of local ancestry linkage disequilibrium (LAD) and the variance of ancestry in a population as a function of the number of generations since admixture. This assortment effect can induce errors in demographic inference of admixed populations when methods assume random mating. We derive closed form formulae for LAD under an assortative-mating model with and without migration. We observe that LAD depends on the correlation of global ancestry of couples in each generation, the migration rate of each of the ancestral populations, the initial proportions of ancestral populations, and the number of generations since admixture. We also present the first direct evidence of ancestry-assortment in African Americans and examine LAD in simulated and real admixed population data of African Americans. We find that demographic inference under the assumption of random mating significantly underestimates the number of generations since admixture, and that accounting for assortative mating using the patterns of LAD results in estimates that more closely agrees with the historical narrative.

Published: November 2016

BACKGROUND AND OBJECTIVES:Convulsive seizures account for 15% of pediatric air transports. We evaluated seizure treatment received in community hospital emergency departments among transported patients for adherence to recommended management.METHODS:This study was a retrospective cohort study of children transported for an acute seizure to a tertiary pediatric hospital from 2010 to 2013. Seizure treatment was evaluated for adherence to recommended management. The primary outcome was intubation.RESULTS:Among 126 events, 61% did not receive recommended acute treatment. The most common deviation from recommended care was administration of &gt;2 benzodiazepine doses. Lack of adherence to recommended care was associated with a greater than twofold increased risk of intubation (relative risk 2.4; 95% confidence interval, 1.4–4.13) and 1.5-fold increased risk of admission to the ICU (relative risk 1.65; 95% confidence interval, 1.24–2.16). Duration of ventilation was commonly &lt;24 hours (87%) for patients who did or did not receive recommended acute seizure care. Among events treated initially with a benzodiazepine, only 32% received a recommended weight-based dosage, and underdosing was most common.CONCLUSIONS:Adherence to evidence-based recommended acute seizure treatment during initial care of pediatric patients using medical air transportation was poor. Intubation was more common when patients did not receive recommended acute seizure care. Educational efforts with a sustained quality focus should be directed to increase adherence to appropriate pediatric seizure treatment of children in community emergency departments.

Published: November 2016

Background and aims
The inclusion of Internet Gaming Disorder (IGD) in Section III of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders has increased the interest of researchers in the development of new standardized psychometric tools for the assessment of such a disorder. To date, the nine-item Internet Gaming Disorder Scale – Short-Form (IGDS9-SF) has only been validated in English, Portuguese, and Slovenian languages. Therefore, the aim of this investigation was to examine the psychometric properties of the IGDS9-SF in an Italian-speaking sample.

Methods
A total of 757 participants were recruited to the present study. Confirmatory factor analysis and multi-group analyses were applied to assess the construct validity. Reliability analyses comprised the average variance extracted, the standard error of measurement, and the factor determinacy coefficient. Convergent and criterion validities were established through the associations with other related constructs. The receiver operating characteristic curve analysis was used to determine an empirical cut-off point.

Results
Findings confirmed the single-factor structure of the instrument, its measurement invariance at the configural level, and the convergent and criterion validities. Satisfactory levels of reliability and a cut-off point of 21 were obtained.

Discussion and conclusions
The present study provides validity evidence for the use of the Italian version of the IGDS9-SF and may foster research into gaming addiction in the Italian context.

Published: November 2016

We provide the first list of the ichthyofauna from the Ajó river, a water course situated at the southward border of the Samborombón bay (36°20'12"’ S, 56°54'17" W), a RAMSAR site in Argentina. These results were obtained bi-monthly along two years. Forty-five species belonging to 26 families and 11 orders were identified. This fish fauna is composed by freshwater, euryhaline and marine species. Richest groups were Perciformes and Characiformes, with 10 species each. A single species, Micropogonias furnieri (whitemouth croaker), represented morethan 70 % of the captured specimens, being juvenile individuals only. Remaining species were also represented by juvenile specimens, confirming the importance of this environment as nursery area, particularly for the whitemouth croaker.

Possibilities of the Application of Digital Games in the Implementation of the Curriculum of Arts Subject
Authors: Vitytė Birutė 
Published: November 2016

Digital games that involve entertainment, relaxation and technology are very attractive to modern students, while the traditional learning/teaching methods are inefficient and unattractive to them due to the change in learning habits. Surveys testify the successful incorporation of digital games into the curricula of Nature, Mathematics, Foreign Languages and other subjects and allow assuming that they might also be incorporated into the curriculum of the subject of Arts; therefore, this article investigates and reveals the possibilities of the application of digital games in the implementation of the curriculum of Arts subject.
Many different interpretations of the concept of a digital game show that it is a manifold and multifaceted phenomenon. In addition to the concept of a “digital game” which can be understood in its broadest sense as the integration of technology and entertainment, the concepts of serious games, game-based learning / digital game-based learning, edutainment, and lecture games can also be encountered in the education contexts.
Digital games can be incorporated into the subject of Arts first of all as a phenomenon of modern art. In certain aspects, digital games can be attributed to pop art and they have certain connections with installation art and, no doubt, with video and optic art and other art branches. The idea of digital games as a form of art is still questioned but some researchers suggest that their artistic value should be grounded on the analogy with art cinema. Cinema is undoubtedly considered a form of art although it is understood that not all films are works of art but, instead, an expression of the popular culture.
Digital games can be incorporated into art classes as a means of artistic expression in several different ways. The first method is the creation of a digital game as an art object during art classes. The second method involves playing already created digital games as the tool/means of development of certain artistic expression abilities. Surveys show that children under 10 years of age are already capable of designing games: their script, graphics and other elements. Teenagers and older students are often capable of controlling programs intended for professionals. The process of creation of a digital game is analogous to the process of creation of any other art work but, according to the researchers, the nature of such creative work offers more education possibilities in certain aspects in comparison to traditional creative activities. The playing of digital games during art classes could be applied instead of traditional methods aiming to train the composing, designing and modelling abilities of the students or to deepen their knowledge on art history. Learning through digital gaming is an attractive and engaging experience to modern students who cannot learn and read consistently but are rather inclined to act and learn through experimenting; therefore, digital games can also be incorporated into art classes as a motivating element.

So that, purpose of this study will know implementation of urban air quality management policy related to transportation by system model approach. The matter will be studied are policy instruments, resources and management. This study is qualitative study. In this study,primary and secondary data will be used. Primary data are collected from in depth interview with competent sources such as Regional Parliamentary, Law Bureau, Regional Authority for Environmental Impact, Transportation Department, Health Department and Samsat. Secondary data are collected by conducting documents. The study result showed that policy instrument has existed, but they are perceived only effective for BPLHD, real law enforcement has been not implemented because system and coordination are not optimal, human and money resources are minimal, and there is no strategic planning so that management and coordination are not optimal. Therefore, to make implementation of urban air quality management policy become effective, the factors should be respected by related parties especially policy makers and policy implementers.Key words: Air quality, urban, implementation, policy, transportation
Social Networking Sites, Depression, and Anxiety: A Systematic Review
Authors: Seabrook Elizabeth M , Kern Margaret L , Rickard Nikki S 
Published: November 2016

BackgroundSocial networking sites (SNSs) have become a pervasive part of modern culture, which may also affect mental health.ObjectiveThe aim of this systematic review was to identify and summarize research examining depression and anxiety in the context of SNSs. It also aimed to identify studies that complement the assessment of mental illness with measures of well-being and examine moderators and mediators that add to the complexity of this environment.MethodsA multidatabase search was performed. Papers published between January 2005 and June 2016 relevant to mental illness (depression and anxiety only) were extracted and reviewed.ResultsPositive interactions, social support, and social connectedness on SNSs were consistently related to lower levels of depression and anxiety, whereas negative interaction and social comparisons on SNSs were related to higher levels of depression and anxiety. SNS use related to less loneliness and greater self-esteem and life satisfaction. Findings were mixed for frequency of SNS use and number of SNS friends. Different patterns in the way individuals with depression and individuals with social anxiety engage with SNSs are beginning to emerge.ConclusionsThe systematic review revealed many mixed findings between depression, anxiety, and SNS use. Methodology has predominantly focused on self-report cross-sectional approaches; future research will benefit from leveraging real-time SNS data over time. The evidence suggests that SNS use correlates with mental illness and well-being; however, whether this effect is beneficial or detrimental depends at least partly on the quality of social factors in the SNS environment. Understanding these relationships will lead to better utilization of SNSs in their potential to positively influence mental health.

Published: November 2016

Sifat mekanika dari kayu gergajian adalah persyaratan terpenting dalam banyak penerapan khususnya untuk keperluan konstruksi. Paper ini merupakan lanjutan dari penelitian sifat fisika kayu di tiga tempat tumbuh (Panggang, Playen, Nglipar) hutan rakyat Kabupaten Gunungkidul. Pengujian sifat mekanika dilakukan mengacu pada British Standards 373:57. Hasil penelitian menunjukkan bahwa kayu yang diteliti termasuk dalam kelas kuat II-III. Dari perhitungan analisis varian, tempat tumbuh berpengaruh nyata pada modulus patah (MoR) keteguhan lengkung statik, keteguhan tekan tegak lurus serat maksimum, keteguhan geser, dan kekerasan. Secara keseluruhan, kecuali untuk nilai MoR, sampel kayu dari Nglipar memberikan nilai kekuatan yang lebih tinggi. Pengaruh arah aksial dan radial pohon secara umum tidak begitu terlihat pada semua parameter kekuatan kecuali di keteguhan belah. Meskipun berkorelasi secara linier, hanya korelasi moderat yang diamati dari hubungan sifat mekanika (MoR/keteguhan geser) dan kerapatan dasar. Tidak ada korelasi nyata antara kerapatan dasar dan modulus elastisitas keteguhan lengkung statik serta antara kerapatan dasar dan keteguhan tekan sejajar serat maksimum.Kata kunci: Tectona grandis, sifat mekanika, kerapatan dasar, hutan rakyat, Gunungkidul. A study of teak wood quality from community forests in Gunungkidul IV. Mechanical PropertiesAbstractMechanical properties of sawn timber are the most important characteristics in many applications, particularly for structural timber. The previous paper in this series reported on the physical properties of teak trees at different sites (Panggang, Playen, Nglipar) from community forests in Gunungkidul regency. In this study, the mechanical properties were evaluated according to British Standards 373:57. The results showed that the timber were classified in the II-III of strength class. By analysis of variance, site factor affected the values of modulus of rupture (MoR) in statical bending strength, maximum compression perpendicular to grain strength, shear strength and hardness. In general, except for MoR, the wood samples from Nglipar gave higher strength levels. Except for cleavage strength, the effects of the axial and radial position of the tree on mechanical properties were mostly negligible. Although linearly related, only modest correlations were observed between the mechanical parameters (MoR/shear strength) and basic density. No significant correlation was found between the values of basic density and modulus of elasticity of static bending strength as well as between basic density and the strength of maximum compression parallel to grain.

Pembentukan Kesatuan Pengelolaan Hutan (KPH) menjadi salah satu prioritas kebijakan Kementerian Lingkungan Hidup dan Kehutanan. Kebijakan ini diharapkan dapat menjadi solusi bagi berbagai permasalahan mendasar pengelolaan hutan di Indonesia, seperti tata kelola yang buruk, ketidakjelasan hak tenurial, dan lemahnya kapasitas dalam manajemen hutan. KPH dikonseptualisasikan sebagai penyelenggara pengelolaan hutan di tingkat tapak. Kebijakan pembangunan KPH yang diatur oleh pusat dipandang dapat menambah kompleksitas terhadap struktur pengurusan dan pengelolaan yang sudah ada selama ini. Makalah ini membahas konsep tata hubungan kelembagaan dalam kebijakan KPH.Kata kunci: KPH, pengurusan, kelembagaan, kewenangan, resentralisasi Direction of Institutions and Bureaucracies of Forest Management Units (FMUs) in Indonesia AbstractThe establishment of Forest Management Units (FMUs) has been made as one of the top policy priorities by the Ministry of Environment and Forestry. The policy is expected to become a solution for problems regarding to the management of forests in Indonesia, e.g. poor forest governance, tenurial problems, limited capacity in the management of forests. FMU is conceptualized as a forest management agent/ institution at the field. The policy of establishing FMUs is often viewed to add complexities of the current forest administration and management structures. This paper discusses concepts of institutions and bureaucracies of the FMU policy.
DISKRESI ANGGOTA KEPOLISIAN NEGARA REPUBLIK INDONESIA DALAM PENANGANAN AKSI UNJUK RASA DAN IMPLIKASINYA TERHADAP KETAHANAN WILAYAH (STUDI DI KEPOLISIAN RESORT KOTA YOGYAKARTA)
Authors: Saputro Legowo 
Published: November 2016

Penelitian ini bertujuan untuk: Pertama, mengetahui penerapan dikresi anggota kepolisian dalam penanganan aksi unjuk rasa, terkait bentuk tindakan dan pertimbangannya serta kendala; dan Kedua, implikasinya terhadap ketahanan wilayah.Penelitian ini menggunakan metode deskriptif kualitatif yaitu pencarian dan pengumpulan data yang berupa pendapat atau gagasan, fenomena, gambar serta dokumen yang berkaitan dengan diskresi anggota kepolisian dalam penanganan aksi unjuk rasa. Data diperoleh dengan wawancara mendalam, pengamatan serta studi kepustakaan dan dokumen, yang selanjutnya dianalisis dan dituangkan dalam bentuk kata-kata dan gambar sehingga memberikan gambaran yang jelas tentang obyek penelitian. Penelitian dilakukan di Kepolisian Resort Kota Yogyakarta dengan mengambil sampel beberapa Anggota Polresta Yogyakarta dan Polda DIY, pengunjuk rasa, masyarakat,dan ahli hukum. Diskresi yang diterapkan oleh Anggota Kepolisian Resort Kota Yogyakarta dalam penanganan aksi unjuk rasa berupa toleransi atas pelanggaran pengunjuk rasa dalam hal surat pemberitahuan dan pelaksanaan aksi unjuk rasa, dan tindakan tersebut sekaligus merupakan pengabaian ketentuan dalam penanganan aksi unjuk rasa oleh Polisi. Kendalanya berupa pemahaman yang sempit serta dangkal terhadap diskresi oleh Polisi, sanksi yang diberikan bersifat personal, tanggapan negatif dari masyarakat dan pengunjuk rasa. Diskresi Anggota Kepolisian Resort Kota Yogyakarta dalam penanganan aksi unjuk rasa berakibat, yaitu: Pertama, akibat positif berupa terciptanya stabilitas wilayah di Kota Yogyakarta dan berdampak terhadap ketahanan wilayah pada aspek ideologi, politik, sosial budaya dan keamanan; Kedua yaitu, akibat negatif berupa anggapan masyarakat bahwa pelanggaran yang dilakukan oleh pengunjuk rasa merupakan hal yang benar, apabila diskresi yang diterapkan tidak dipahami dengan baik oleh polisi. Kendala yang ada harus diatasi dengan memberikan pemahaman dan pengetahuan yang cukup tentang diskresi kepolisian, khususnya kepada Anggota Kepolisian Resort Kota Yogyakarta, dan kepada masyarakat maupun pengunjuk rasa
Bier's block

Published: November 2016

Introduction: Intravenous Regional Anesthesia (IVRA) has been first described in 1908 by the German surgeon August KG Bier. Although the technique was convenient to perform and effective in giving surgical anesthesia, the recent plexus block techniques have largely replaced the "Bierâ€™s block" instantly because of time limitations and safety considerations of IVRA. Throughout the years, modifications in procedure and new pharmacologic adjuvants have shown to prevent toxic reactions to anesthetics and mitigate limitations of IVRA, still IVRA can be preferred as choice of anesthesia for short procedures.
Case Report: We present a case of 86 yr old male who was operated for radius fracture after a fall injury under Bier's Block or IVRA technique. Conclusion: IVRA can be the choice ofanesthesia for short procedures because of rapid onset of anesthesia, easy administration and cheaper cost with special considerations on its side effects, complications which can be the outcome of technical errors.
