An observational study of recess quality and physical activity in urban primary schools
Authors: Massey William Vincent , Stellino Megan B , Geldhof John 
Published: February 2020

Abstract
Background To date, there is scant literature that examines the recess context concurrent with, but separate from, levels of physical activity. The primary purpose of the current study was to examine how recess quality impacted physical activity levels, and how this was moderated by gender. A secondary purpose was to examine if differences in children’s engagement in activities occurred between recess sessions scored as low- or high- quality. Methods This was an observational study of children at 13 urban elementary schools in the U.S. Across the 13 schools, data were collected at 55 recess sessions, with 3,419 child-level observations ( n= 1,696 boys; n= 1,723 girls). Physical activity data were collected using Fitbit accelerometers, recess quality data were collected using the Great Recess Framework – Observational Tool (GRF-OT), recess engagement data were collected using the Observation of Playground Play (OPP), and basic psychological need satisfaction (BPNS) data were collected using a modified version of the BPNS for recess physical activity survey. Primary analyses were conducted using Hierarchical Linear Modeling (HLM) with children nested within recess sessions. Results Gender moderated the relationship between adult engagement and moderate-to-vigorous physical activity (MVPA) (b= .012; 95% CI .001, .024), student behavior and MVPA (b= -.014; 95% CI -.021, -.007), and student behaviors and light physical activity (b= .009, 95% CI .003, .015). Both boys and girls engaged in more play during recess sessions scored as high quality on the GRF-OT. Children reported higher levels of basic psychological need satisfaction at recesses sessions scored as high quality on the GRF-OT. Conclusions Results of the current study showed that the quality of the recess environment, and the interactions of both adults and students in that environment, need to be taken into consideration in future school-based recess studies.
Interruption—Intervention: On the interval between literature and music in Jean Luc Nancy's "Myth Interrupted"
Authors: Villegas Vélez Daniel 
Published: February 2020

This paper focuses on the role of mimesis and more specifically, the role of musical performance in creating communities by examining the oscillations between muthos and logos that inform contemporary thinking around community and institutions.The starting point is Jean-Luc Nancy’s (1991) intervention—or interruption— into the totalitarian or “immanentist” tendency of myth, a tendency that is especially at play in European modernity’s image of itself as a myth-less community as well as in contemporary or “(new) fascism” (Lawtoo 2019). For Nancy, the notion of myth must not be rejected but “interrupted,” so that “there is a voice of community articulated in the interruption, and even out of the interruption itself” (1991). What replaces myth in his account is “literature” a notion that arguably informs the contemporary movement of performance philosophy (Corby 2015). Why literature and not musical performance? In posing this question, this paper turns back to ancient Greek mousikē as a sonorous performance that interrupts the interruption, giving rise to the interval. Countering the myth of myth, I develop an account of mousikē that mobilizes rhythm, spacing, and iterability to suggest a notion of community that exchanges communion for performative communication, producing an intervened institution interrupted from within: an in— stitution.
Toxic Climates: Earth, people, movement, media
Authors: Haldrup Michael , Samson Kristine , McGowan Madeleine Kate 
Published: February 2020

Planet Earth is toxic. Its atmosphere unbreathable. Its environments deadly intoxicated by the dehumanizing forces of xenophobia, environmental degradation and violence. As its peoples are increasingly on the move to make a worthy living exclusion, borders and conflict is a norm rather than an exception. And – as toxic substances dissipate and spreads through media and circulating representations they clouds the sight to the human beings in front of us. In the face of the intoxicating and dehumanizing forces at play, we need remedies for sobering up rather than intoxication. Remedies for living with contamination and hybridity rather than altering these states. Partly inspired by Levinas and his ethics of the “nakedness of a face, the absolute defenseless face, without covering, clothing or mask” (1998: 21) and partly by Anna Tsings’ more recent call for “contamination” as a catalyst from which future ”world-making projects, mutual projects and new directions – may emerge” (2015: 27) we propose a radical humanizing intervention in - and beyond - institutions. A contamination of academic institutions and media with testimony from people living the change. A contamination of thought with action. A contamination of activism with thinking. In a cooperation between academic performance researchers and media activist collective Other Story we explore media activism as ways of expressing and enacting citizenships. Conceiving of thinking as a practice that “interrupts all ordering activities and is interrupted by them” (Arendt 1971: 197) we think through and with embodied others and their material lives rather than about them. Hence, the presentation will address interventions and evidence of staging a “radical softness” in the meeting with people who live through current planetary change and explore potentials for emerging shared sensibilities affecting our own embodied citizenships in the encounter with others in these toxic climates.

Authors: Attar Hani , Khosravi Mohammad R. , Igorovich Shmatkov Sergiy , Georgievan Kuchuk Nina , Alhihi Mohammad 
Published: February 2020

Background:
Multi-Service Streams Network (MSSN) has become such a popular technique
in modern applications including, medical fields for E-health applications, such as medical
systems and patient monitoring network systems. Recent E-health researches intend to compare
MSSN data communications with traditional methods such as the internet.

Methods:
Based on the above-mentioned fact, the proposed work in this paper is directed to obtain a
detailed analysis of the MSSN applied over E-health, using the G/G/1 analysis method, including
traffic probabilistic-time characteristics to establish its self-similar processes. Moreover, the paper
proposes the purpose of estimating the queue service efficiency and overload management by the
essential criterion, which takes into account the time delay, time jitter, and the packet loss probability
expected in the E-health applications. Based on the necessary standard for the proposed uses, the
results of queue operations and also relevant buffer space algorithms are evaluated. Moreover, the
estimated qualitative measurement of the network development for the proposed model is obtained
and compared with the most common techniques adapted in E-health applications.

Results:
The collected results show that MSSN is an applicable technique to be applied over the Ehealth
applications mainly on its excellent time delay, jitter, packet losses probability, and others.

Conclusions:
The main aim of this paper is to obtain a fully detailed analysis of the MSSN that is
applied over E-health applications, using the mass service capacity for the mathematical model class
G/G/1 in the most general case of a single-channel system.

Published: February 2020

Background:
Vegetable oil of Fatty Acid Methyl Esters (FAME) that is obtained by triglycerides
of transesterification in the presence of methanol, recently, has been highly regarded by
scholars for use in diesel engines. These oils can be used as biodiesels in diesel engines and have various
benefits (these fuels are renewable, biodegradable, and nontoxic).

Objective:
In this work, many studies are reviewed in the field of using vegetable oils as biodiesel in
diesel engines. Moreover, a simulation study is conducted to compare oxygen and peak pressure of a
diesel engine fueled by three different biodiesels in comparison to diesel fuel. We have examined the
chemical ignition delay time and kinetic viscosity of biodiesel in the combustion process of diesel engine
and the effects of these factors are evaluated on air–fuel mixing and subsequent combustion.

Banyak kasus-kasus kenakalan bahkan kejahatan dikaitkan dengan isu degradasi karakter. Pemerintah mengupayakan hal tersebut dengan mulai berfokus pada pendidikan karakter. Pendidikan karakter sudah harus ditanamkan sejak dini sebagai modal dan pondasi awal terbentuknya sikap dan karakter individu. Salah satu indikator karakter yang menjadi modal dasar tersebut yaitu kejujuran. Anak usia dini dikenal sebagai manusia paling jujur karena kepolosannya. Hanya saja jujur bukan hanya mengatakan hal apa adanya, tapi juga terkait bagaimana anak mengetahui perilaku yang tepat dan tidak tepat. Penelitian ini bertujuan untuk mendeskripsikan bagaimana profil kejujuran anak usia 5-6 Tahun di RA A- Taufiq Kota Tasikmalaya. Penelitian deskrpitif kuantitiatif ini dilakukan melalui tes kejujuran pada 15 anak saat kegiatan pembelajaran. Dari tes kejujuran tersebut didapat bahwa anak usia 5-6 tahun di RA-AT Taufik sudah memiliki dasar kejujuran yang baik. Hanya saja, semakin anak tumbuh dan berinteraksi dengan lingkungannya semakin anak akan mendapatkan pengaruh pengaruh lain yang dapat menguatkan atau bahkan melemahkan karakternya. Sehingga menamkan sikap jujur melalui upaya pendidikan karakter harus senantiasa dibangun dan dipertahankan oleh lingkungan sekitarnya untuk membentuk karakter yang kuat dari setiap individu sehingga kasus kenakalan dan kejahatan bisa berkurang.

Authors: Kurniawan Afiri N 
Published: February 2020

Kegagalan pendidikan karakter dapat berdampak signifikan pada praktek dan sudah saatnya bagi para peneliti pendidikan karakter untuk mempelajari beberapa alasan mengapa penelitian – praktek tampaknya berjauhan dalam bidang pendidikan karakter. Sosiologi dapat digunakan untuk membahas bagaimana rekayasa praktek pendidikan karakter digunakan. Melalui cara ini, maka pendidikan karakter yang dapat dikembangkan pada jenjang Sekolah Menengah Atas (SMA) tidak hanya selalu berkaitan/berfokus pada etika (karakter moral), namun juga memperhatikan keunggulan (karakter kinerja) yang muncul dalam kurikulum sosiologi SMA

The work is devoted to a universal resource-saving method of parts processing - electric spark alloying (ESA). It is used both in manufacturing and repairing. This method allows you to apply reinforced and restored coatings to various objects (parts, tools, and tooling) regardless of their shapes and sizes.Purpose of reseach is to show high universality and efficiency of ESA method on the examples of its practical application for problem solving of machine-building production and repair.Methods. The work is analytical and carried out taking into account authors' practical experience.Results. Some information about ESA method, coating forming mechanism, their thickness and properties is given. Implementing strengthening technologies wear resistance is increased by 2-5 times and more by coatings of increased hardness using electrodes from metal-ceramic hard alloys based on carbides of TiC, WC and other hard compounds. The expediency of recovery technologies is shown: wear of most parts (about 85%) of various techniques does not exceed 200 um and their recovery cost is usually no more than 25-30% of a new part cost; recovered parts resource is commensurate or exceeds new parts resource. Adjusting and restoring technologies are described using specific examples.Conclusion. Given examples of practical application of ESA method confirm high universality and efficiency of this method for solving machine-building and repair production problems. Obtained results can be used in method selecting for strengthening or reducing of various objects from metals and alloys (parts of machines, tools, technological equipment) taking into account ESA advantages.
College Student Problematic Internet Use and Digital Communication Medium Used With Parents: Cross-Sectional Study
Authors: Kerr Bradley , D'Angelo Jon D , Diaz-Caballero Ali , Moreno Megan A 
Published: February 2020

Background
Problematic internet use (PIU) is associated with mental health concerns such as depression and affects more than 12% of young adults. Few studies have explored potential influences of parent–college student digital communication on college students’ risk of PIU.

Objective
This study sought to understand the relationship between parent–college student digital communication frequency via phone calls, text messages, and Facebook contacts and PIU among college students.

Methods
Incoming first-year students were randomly selected from registrar lists of a midwestern and northwestern university for a 5-year longitudinal study. Data from interviews conducted in summer 2014 were used. Measures included participants’ daily Facebook visits, communication frequency with parents via phone call and text message, and 3 variables related to Facebook connection status and communication: (1) parent–college student Facebook friendship status, (2) college student blocking personal Facebook content from parent, and (3) Facebook communication frequency. PIU risk was assessed using the Problematic and Risky Internet Use Screening Scale. Analysis included participants who reported visiting Facebook at least once per day. Multiple linear regression was used, followed by a post hoc mediation with Hayes process macro to further investigate predictive relationships among significant variables.

Results
A total of 151 participants reported daily Facebook use and were included in analyses. Among these participants, 59.6% (90/151) were female, 62.3% (94/151) were from the midwestern university, and 78.8% (119/151) were white. Mean Facebook visits per day was 4.3 (SD 3.34). There was a collective significant effect between participant daily Facebook visits, college student–parent phone calls, texts, and all 3 Facebook connection variables (F6,144=2.60, P=.02, R2=.10). Phone calls, text messages, and Facebook contacts were not associated with PIU risk. However, two individual items were significant predictors for PIU: participant daily Facebook visits were positively associated with increased PIU risk (b=0.04, P=.006) and being friends with a parent on Facebook was negatively associated with PIU risk (b=–0.66, P=.008). Participant daily Facebook visits were not a significant mediator of the relationship between college student–parent Facebook friendship and PIU risk (b=–0.04; 95% CI –0.11 to 0.04).

Conclusions
This study did not find support for a relationship between parent–college student digital communication frequency and PIU among college students. Instead, results suggested Facebook friendship may be a protective factor. Future studies should examine how a parent-child Facebook friendship might protect against PIU among children at varying developmental stages.
