‘Unmute This’: Captioning an (audio)visual microgenre
Authors: Harper Paula 
Published: July 2017

Abstract
I argue that ‘Unmute This’ videos constitute an Internet video microgenre, and as particular intersections of behaviour, devices and content, these videos function as an entry point into a number of broader issues within twenty-first–century audio-visual media and participatory behaviour. First, the moment of encounter with an ‘Unmute This’ video post elucidates a reframing of the digital sensorium: how ears and eyes, watching and listening, are configured and reconfigured in tandem with ubiquitous devices like smartphones and earbuds, and via the affordances and behaviours of various digital and social media platforms. Secondly, directives to ‘Unmute This’ point to a distinct mode of online socialization, a particular ‘sociality’ of social media. In collaboration with the devices and platforms of their everyday experience, users build a vernacular theory of media use based on their own behaviours and practices. They then implement that theory while seeking to impart an ideal content experience for others, platform users potentially far removed from the poster/commenter’s own acquaintances. In this article, then, I begin by unpacking the implementation of autoplaying video and the assemblage of the ubiquitous digital sensorium – that is, what sensory behaviours and practices map on to dealing with autoplaying video, at least as suggested by ‘Unmute This’ directives. I then consider ‘Unmute This’ videos as a genre, sketching out some patterns in the form and content of videos that one might be most likely directed to ‘UNMUTE IMMEDIATELY’, and interrogating how such stylistic and formal details might be emergent in response to platform affordances, ubiquitous devices and norms of Internet-mediated sociality. Finally, I suggest a theorization of vernacular media theory, drawn from the particulars of ‘Unmute This’ videos and their creators and disseminators, and I unpack some implications for the kinds of assumptions about sociality, behaviour and trust that are built into such theorizing and user responses to it.
O cinema existe e resiste. Longa duração, análise fílmica e espectatorialidade nos filmes de Lav Diaz
Authors: Ramos Monteiro Lúcia 
Published: July 2017

A longa duração – de planos e filmes –, ao lado de uma sensação difusa de lentidão, vem sendo apontada pela crítica e pela academia como tendência do cinema independente contemporâneo, relacionada ao uso dos suportes digitais de gravação e exibição. Tal característica pode de modo geral ser encontrada em toda a obra do cineasta filipino Lav Diaz. Neste artigo, a questão será pensada sobretudo no estudo de dois de seus filmes, Florentina Hubaldo, CTE (2012) e A Lullaby to the Sorrowful Mystery (2016), em primeiro lugar como dificuldade para a análise fílmica, exacerbando o paradoxo descrito por Raymond Bellour em “Le texte introuvable” (1979), e em seguida em meio às interrogações sobre a atualidade da sala de cinema. Para além da discussão à realidade e ao realismo do cinema a partir da ontologia proposta por Bazin (1993), aqui a questão do plano longo será abordada sobretudo do ponto de vista da postura espectatorial, tanto com relação a sua atenção – como os filmes de Diaz direcionam (ou abstêm-se de direcionar) a atenção do espectador? – quanto da experiência comunitária das salas de cinema.

Published: July 2017

Abstract
A 14-year-old boy presented to our hospital with a chief complaint of difficulty in opening his mouth and a burning sensation on eating spicy food. The oral mucosa showed generalized diffused blanching and he was unable to protrude his tongue. For 6 years he had habitually chewed gutkha – a mixture of betel nut and tobacco for several minutes a day. This oral submucous fibrosis condition is very rare in young patients. The case highlights the link between oral submucous fibrosis and the regular use of areca nut (gutkha) products in a young boy.
Seeking sexual health information? Professionals’ novel experiences of the barriers that prevent female adolescents seeking sexual health information
Authors: McKellar Kerry , Little Linda , Smith Michael A. , Sillence Elizabeth 
Published: July 2017

AbstractObjectiveSexual health professionals are key stakeholders in implementing sexual health intervention programmes, yet their views are largely absent from the literature. Sexual health professionals provide a unique perspective on teen sexual health issues as they engage in confidential discussions with a wide range of teenagers. This study aimed to provide an in-depth exploration of professionals’ perceptions of teenagers’ sexual health information seeking practices and barriers. Furthermore, the research provided a unique re-examination of key predictors of risky sexual behaviours, which have been highlighted by previous research.MethodsNine semi-structured interviews were undertaken with sexual health professionals to explore their perceptions of teenagers’ sexual health information seeking practises and barriers. Subsequently the professionals rank ordered the 57 factors identified in previous research in terms of their perceived importance in predicting risky sexual behaviours.ResultsFour themes emerged: “society and media”; “environment and family”; “peer influences”; and “the self”. The rank order task confirmed that 33 of the 57 factors were perceived as highly important by sexual health professionals.ConclusionSociety, peers, environment and family are perceived as barriers to teenagers seeking reliable sexual health information, but these are dependent on the individual person. An individual with higher self-esteem is more confident in seeking sexual health information and applying this knowledge appropriately. Self-esteem was also identified as a key perceived predictor of risky sexual behaviours. Therefore, there is scope for intervention programmes targeting self-esteem and knowledge, so teenagers have the confidence to seek out sexual health information and to make their own informed sexual health decisions.
Unsteady Boundary Layer Flow and Convective Heat Transfer of a Fluid Particle Suspension with Nanoparticles over a Stretching Surface

Published: July 2017

AbstractWe analyzed the effects of Biot number and non-uniform heat source/sink on boundary layer flow and nonlinear radiative heat transfer of fluid particle suspension over an unsteady stretching surface embedded in a porous medium with nanoparticles. We considered conducting dust particles embedded with -water nanopartcles. The governing equations are transformed into nonlinear ordinary differential equations by using local similarity transformations and solved numerically using Runge–Kutta-Fehlberg-45 order method along with shooting technique. The effects of non-dimensional parameters on velocity and temperature profiles for fluid phase and dust phase are discussed and presented through graphs. Also, friction factor and Nusselt number are discussed and presented through graphs. Comparisons of the present study were made with existing studies under some special assumptions. The present results have an excellent agreement with existing studies. Results indicated that the enhancement in fluid particle interaction parameter increases the heat transfer rate and depreciates the wall friction. Also, radiation parameter has the tendency to increase the temperature profiles of the dusty nanofluid.
The (mis)use of development in international investment law: understanding the jurist’s limits to work with development issues
Authors: Monebhurrun Nitish 
Published: July 2017

AbstractThe decolonization period was characterized by the adoption of investment protection agreements with the objective of serving the purposes of both transnational corporations and newly decolonized States. These agreements are primarily meant to protect private international investments and, incidentally, they have been presented as instruments of development: protecting international investments to foster development. Many newly decolonized States signed and ratified such treaties with the aim of attracting foreign investors – but also to maintain existing ones; what was expected in return was a contribution to their development. This article studies the legal relationship which consequently exists between international investment law and development, but at the same time, it highlights the flagrant misuse of the concept of development in practice. In this law field, both the Global North and the Global South tend to envision development in a way which is deprived of all technical and scientific grounds. The paper firstly explains how the objective of development, rooted in such investment agreements, acquired a legal function. Bilateral investment agreements were a means to forge newly decolonized States’ expectations and belief concerning the paramount necessity to protect foreign investments so as to benefit in terms of development. In the international investment legal practice, the contribution to the host State’s development by the foreign investor has been frequently used as a criterion to identify an investment: to be protected by an investment agreement any activity must necessarily be identified as an investment. As the latter knows no definition some tribunals have considered that one of the criteria to identify an investment is a contribution to the development of the host State by the potential investor. Theoretically, this seems to consider the interests of developing States in their relationship with transnational corporations. However, and this is the second point, development has itself never really been defined – and still is not in this law field. It is hence used and applied as an undefined concept. Development is in fact referred to as an image, as a symbol, but never in its technical aspects. Accordingly, such reference made to the concept of development in international investment law is far from convincing and forges skepticism on its intrinsic necessity and use. In this vein, it raises the thorny question of the jurist’s technical competence to assess what development is and how it can – technically – be used in law.
Thin-wall injection molding of high-density polyethylene for infrared radiation system lenses

Published: July 2017

Abstract
High-density polyethylene (HDPE) lenses are used for infrared radiation (IR) systems, such as radiation thermometers to transmit the IR of the 10 μm region. High IR transmittance and low visible ray (VR) transmittance are necessary for IR system lenses. This experimental investigation of thin-wall injection molding was conducted using 0.5 mm cavity thickness with a disk shape, finished to a mirror-like surface. As factors affecting transmittance, we evaluated the thickness, surface roughness, crystallinity, internal structure, and molecular chain orientation of molded parts, which were produced using four HDPE melt flow rates (MFRs). The changed molding conditions were mold temperature and holding pressure. Results showed that the thin-molded parts had higher IR transmittance. The thin-molded part was obtained with the smallest MFR of 5. Furthermore, the VR transmittance decreased when the molecular chain orientation in the molded parts was small and the crystallinity was high. The small orientation and high crystallinity were obtained simultaneously with the largest MFR of 42. Therefore, it was impossible to obtain high IR transmittance and low VR transmittance simultaneously by a change of MFR. This study confirmed that surface roughness and crystallinity do not affect transmittance.

AbstractParkinson’s disease (PD) is a neurodegenerative disease of unknown etiology that is thought to be caused by a complex combination of environmental and/or genetic factors. Air pollution exposure is linked to numerous adverse effects on human health, including brain inflammation and oxidative stress, processes that are believed to contribute to the development and progression of PD. This review provides an overview of recent advances in the epidemiology of air pollution and PD, including evidence of the effects of various pollutants (ozone, PM
Indium doping in sol-gel synthesis of In-Sm co-doped xIn-0.05%Sm-TiO2 composite photocatalyst
Authors: Zhang Wenjie , Liu Yuxuan , Pei Xiaobei , Yang Jiao 
Published: July 2017

Abstract
Sol-gel method was used to prepare a novel In-Sm co-doped TiO2 photocatalyst. The materials were characterized by X-ray diffraction, scanning electron microscopy, Fourier transform infrared/far infrared, UV-Vis diffuse reflectance, and N2 adsorption-desorption analyses. Anatase phase TiO2 is formed in the pure and doped TiO2 samples. Anatase TiO2 crystal formation and growing are disturbed by the dopants. The substitution of smaller Ti4+ ions by the larger Sm3+ and In3+ ions causes the expansion of TiO2 cell. The doping of indium and samarium ions has no noticeable influence on the bonding characters of TiO2. A continuous red shift of the absorption edge of xIn-0.05%Sm-TiO2 occurs at increasing indium doping content. Brunauer-Emmett-Teller surface area, average pore size, and total pore volume are enhanced after doping of samarium and indium. The adsorption of methyl orange on the surface of xIn-0.05%Sm-TiO2 increases with rising indium content. The 5%In-0.05%Sm-TiO2 has the maximum photocatalytic activity. About 97.7% of the initial methyl orange is decolorized on 5%In-0.05%Sm-TiO2 after 45 min of irradiation.
The spurious effect of ARCH errors on linearity tests: a theoretical note and an alternative maximum likelihood approach
Authors: Pavlidis Efthymios G. , Tsionas Mike 
Published: July 2017

AbstractLinearity tests against smooth transition nonlinearity are typically based on the standard least-squares (LS) covariance matrix estimator. We derive an expression for the bias of the LS estimator in the presence of ARCH errors. We show that the bias is downward, and increases dramatically with the persistence of the variance process. As a consequence, conventional tests spuriously indicate nonlinearity. Next, we examine an alternative maximum likelihood approach. Our findings suggest that this approach has substantially better size properties than tests based on least-squares and heteroskedasticity-consistent matrix estimators, and performs comparably to a bootstrap technique.
COLQ-mutant congenital myasthenic syndrome with microcephaly: A unique case with literature review
Authors: Al-Mobarak Sulaiman Bazee , Al-Muhaizea Mohammad A. 
Published: July 2017

AbstractCongenital Myasthenic Syndrome (CMS) is a group of inherited neuromuscular junction disorders caused by defects in several genes. Clinical features include delayed motor milestones, recurrent respiratory illnesses and variable fatigable weakness. The central nervous system involvement is typically not part of the CMS. We report here a Saudi girl with genetically proven Collagen Like Tail Subunit Of Asymmetric Acetylcholinesterase (COLQ) mutation type CMS who has global developmental delay, microcephaly and respiratory failure. We have reviewed the literature regarding COLQ-type CMS and to the best of our knowledge this is the first ever reported association of congenital myasthenia syndrome with microcephaly.

Lacerda, LT, Costa, CG, Lima, FV, Martins-Costa, HC, Diniz, RCR, Andrade, AGP, Peixoto, GHC, Bemben, MG, and Chagas, MH. Longer concentric action increases muscle activation and neuromuscular fatigue responses in protocols equalized by repetition duration. J Strength Cond Res 33(6): 1629–1639, 2019—The aim of this study was to investigate the impact of protocols equalized by the repetition duration but composed of different concentric (CON) and eccentric (ECC) durations on muscle activation and neuromuscular fatigue. Seventeen males with previous experience in resistance training performed 3 training protocols (A — 2 second CON: 4 second ECC; B — 3 second CON: 3 second ECC; and C — 4 second CON: 2 second ECC) with the Smith machine bench press exercise, all with 3 sets, 6 repetitions, 3 minutes' rest, and 60% of 1RM. The normalized root mean square of the electromyographic signal (EMGRMS) and mean frequency electromyography (EMGMF) for pectoralis major and triceps brachii muscles were calculated for second and fifth repetitions in each set. The results showed an EMGMF decrease across the repetitions accompanied by a progressive increase of the EMGRMS across the repetitions for all protocols and muscles. The EMGRMS was higher in protocol C when compared with protocol A and B for pectoralis major. The EMGMF was lower in protocols B and C than in protocol A for pectoralis major throughout the sets and repetitions. A higher EMGRMS and a lower EMGMF were observed in protocols B and C compared with protocol A for triceps brachii, solely in the fifth repetition. In conclusion, training protocols conducted with the same repetition duration, but with different concentric and eccentric durations, produce distinct muscle activation and neuromuscular fatigue responses, in which performing longer concentric durations could be the more appropriate strategy to increase muscle activation and neuromuscular fatigue.

Sant'Ana, J, Franchini, E, Murias, JM, and Diefenthaeler, F. Validity of a taekwondo-specific test to measure Vo
2peak and the heart rate deflection point. J Strength Cond Res 33(9): 2523–2529, 2019—This study investigated whether the progressive specific taekwondo test (PSTT) is a valid test to measure peak oxygen consumption (Vo
2peak) and the heart rate deflection point (HRDP) in taekwondo athletes. Eighteen male black belt athletes (25.3 ± 4.8 years; 8.2 ± 4.7 years of practice; 171.8 ± 4.7 cm; 76.1 ± 8.2 kg, and 13.1 ± 2.9% body fat) involved in regional- and national-level competitions performed the PSTT and an incremental treadmill test (IT). The following variables were analyzed: Vo
2peak, respiratory quotient, oxygen consumption at the HRDP (Vo
2HRDP), peak heart rate (HRpeak), HRDP, and peak posttest blood lactate concentration. During the PSTT, the peak kick frequency (FKpeak) and kick frequency at the HRDP (FKHRDP) were also obtained. During the IT, the peak speed and the speed at the HRDP were identified by the Dmax method (the first and last points of the curve were connected by a straight line, and the most distant point of the curve to the line was considered as the HRDP). No differences were observed between Vo
2 responses during the PSTT and IT (p > 0.05). Vo
2peak and Vo
2HRDP presented bias (1.3 ml·kg−1·min−1 and −0.78 ml·kg−1·min−1, respectively) derived from the Bland and Altman plots, with the 95% limits of agreement indicating that the differences between the 2 measures can reach 11% for Vo
2peak and 17% for Vo
2HRDP. The PSTT is a valid tool to assess aerobic power and capacity in taekwondo athletes based on direct comparisons to a treadmill test. The test presents more specific variables for the assessment and training of taekwondo athletes, such as FKpeak and FKHRDP, which can be used to determine and control the effects of training and help coaches in prescribing training programs.
