Markedness and dominance in the ATR harmony system of Diola-Fogny
Authors: Casali Roderic F. 
Published: November 2018

Abstract
Diola-Fogny is a well-known example of a tongue root harmony language with assimilatory dominance of [+ATR] vowels. Less well known, however, are some asymmetries involving the frequency and distribution of [+ATR] and [-ATR] vowels. In addition to being dominant, [+ATR] vowels are subject to restrictions on their occurrence in certain classes of function words and affixes and occur with far lower overall frequency than [-ATR] vowels. In essence, they pattern like a marked sound class. This paper focuses on some implications of these findings for a theoretical topic of interest: markedness relations involving tongue root features. The Diola-Fogny patterns conform quite well to the expectations of a traditional understanding of featural markedness, which equates the dominant value of a feature with the marked one. They are problematic, however, for a widely assumed view of tongue root markedness relations that treats [-ATR] as universally marked in high vowels. Under this view, marked patterning of all [+ATR] vowels (including high [+ATR] [i], [u]) is unexpected. I show that such patterning is intelligible in a framework in which markedness has a representational basis and in which [+ATR] quality is represented by a privative feature [ATR].
“What Is this Place...?” – Howard Barker’s Spatial Scenography
Authors: Kipp Lara Maleen 
Published: November 2018

Abstract
This article seeks to identify some key scenographic principles that govern contemporary British playwright Howard Barker’s stage spaces. The influence of Barker’s dramatic work is widely recognized and has been the subject of sustained academic study for a number of decades. Despite Barker’s scenographic engagement with his own playwriting since the late 1990 s, the corresponding academic engagement with this aspect of his work remains scant. This article therefore offers the first sustained consideration of Barker’s spatial scenography, engaging in a detailed analysis of select examples of Barker’s drama from the late 1990 s to mid-2000s. It also draws upon archival materials of productions by The Wrestling School company to compare the implicit scenography as evident in the play text to its realization in production. The analysis approaches Barker’s spatial scenography through the lens of aesthetic discourse, with particular focus on the notion of the postmodern sublime as postulated by Lyotard and Johnson, among others, in order to discuss the subject matter in a suitably non-reductive, yet critical manner.
History on the Cusp of Myth: J. T. Rogers’ Oslo
Authors: Soto-Morettini Donna 
Published: November 2018

Abstract
J. T. Rogers’ Oslo has had an extraordinary run for new ‘straight’ drama: sell-out performances both in New York and London, and 7 Tony nominations. But what is it? On the face of it, Oslo is a history play – a carefully imagined reconstruction of secret talks that became the precursor to the Clinton/Arafat/Rabin Camp David meetings that resulted in the 1993 Oslo Accords. The subject and the players have been thoroughly researched by J. T. Rogers, and the play’s reception has been largely celebratory. This perhaps is the result of a play-going public’s appreciation of some intelligence in political debate and no doubt an appreciation of the play’s optimism, despite the ultimate failure of the Accords. This paper looks closely at three questions posed by Rogers’ play: 1) IS it a history play, and if so, how does it apprehend/narrate history? 2) Murray Krieger once said that history is the child of myth that never altogether escapes its parentage – is Oslo, in this sense, an unruly child of myth – not so much a history play, as it is a trans-historical political lesson? 3) If Oslo is NOT a history play, to what end does it employ its very specifically researched context?
Simon Stephens, Birdland, and a Few Affects of Neoliberalization
Authors: Chiasson Basil 
Published: November 2018

Abstract
This article explores the ways theatre might inspire a critique of what is arguably most pressing about contemporary neoliberalization—its operation at the level of subjectivity to reform society. The focus in this is Simon Stephens and his play Birdland (2014). Working from extant scholarship that connects Stephens’s work to neoliberalism, the article locates the playwright and his work in relation to a specific history of neoliberalization in Britain and argues that Birdland is a timely political drama because it hones in on certain features and affects of neoliberalization, doing so in ways that open a space for engaging critically with key problems engendered by contemporary capitalism.
Kinetics of nonisothermal dehydration of unirradiated and γ-ray irradiated neodymium (III) acetate hydrate

Published: November 2018

Abstract
Kinetics of dehydration of unirradiated and γ-ray irradiated neodymium (III) acetate hydrate with 103 kGy total γ-ray dose absorbed in air atmosphere were studied by isoconversional nonisothermal method. The dehydration proceeds in two steps with the elimination of 0.8 and 0.4 mol of H2O, respectively. This result indicates that the investigated neodymium (III) acetate hydrate contains 1.2 mol of crystalline water in its structure. The dehydration reactions are best described by nucleation (A
2 model) and gas diffusion (D
4 model) for unirradiated and γ-ray irradiated samples, respectively. Analysis of the kinetic data using linear and nonlinear isoconversional methods showed that the apparent activation energy, Ea
(kJ/mol) is dependent on the conversion degree, α, of the dehydration process. The Ea−α plots for both unirradiated and γ-ray irradiated neodymium (III) acetate hydrate showed that the dehydration is a complex process and contains multistep reactions. The results showed that γ-ray irradiation has a significant effect on the kinetics and thermodynamic parameters of the dehydration reaction. Powder X-ray diffraction showed that neodymium (III) acetate hydrate has a monoclinic system (SG P2/m) and no phase transformation was detected by γ-ray irradiation up to 103 kGy absorbed dose. The system maintains the same crystal structure before and after dehydration.
An HJB approach to a general continuous-time mean-variance stochastic control problem
Authors: Aivaliotis Georgios , Veretennikov A. Yu. 
Published: November 2018

Abstract
A general continuous mean-variance problem is considered for a diffusion controlled process where the reward functional has an integral and a terminal-time component. The problem is transformed into a superposition of a static and a dynamic optimization problem. The value function of the latter can be considered as the solution to a degenerate HJB equation either in the viscosity or in the Sobolev sense (after a regularization) under suitable assumptions and with implications with regards to the optimality of strategies. There is a useful interplay between the two approaches – viscosity and Sobolev.
Enhanced dielectric properties of BaTiO3 ceramics with cerium doping, manganese doping and Ce-Mn co-doping
Authors: Mostafa Myeesha , Rahman Mohammad Jellur , Choudhury Shamima 
Published: November 2018

Abstract
Ba1−xCexTi1−yMnyO3 (where x and y varies from 0.00 to 0.03) ceramic samples are synthesized by conventional solid state reaction technique. The samples are sintered at 1473 K for 4 h. The grain size is observed to increase with increasing dopant and co-dopant concentration. The X-ray diffraction confirmed the cubic phase of these BaTiO3-based ceramics with a small amount of secondary phase. The current density shows a nearly linear relationship with voltage, and the AC resistivity of the samples is observed to decrease with increasing frequency and doping concentration. The dielectric constant and dielectric loss were observed to decrease with frequency in the lower frequency range (0.2–10 kHz), but remained almost the same at the high-frequency region (>10 kHz). Though Ce-doped samples shows better dielectric properties than Mn-doped samples, the Ce-Mn co-doped samples, having improved their dielectric properties, can be used to fabricate different optoelectric devices.

Published: November 2018

AbstractParkinson’s disease, the second major neurodegenerative disease, has created a great impact on the elder people. Although the mechanisms underlying Parkinson’s disease are not fully understood, considerable evidence suggests that neuro-inflammation, oxidative stress, mitochondrial dysfunction, cell proliferation, differentiation and apoptosis are involved in the disease. p38MAPK, an important member of the mitogen-activated protein family, controls several important functions in the cell, suggesting a potential pathogenic role in PD. This review provides a brief description of the role and mechanism of p38MAPK in Parkinson’s disease.
Einstein’s “Clock Hypothesis” and Mössbauer Experiments in a Rotating System
Authors: Kholmetskii Alexander , Yarman Tolga , Yarman Ozan , Arik Metin 
Published: November 2018

Abstract
An extra energy shift between emitted and received radiation on a rotating disc – next to the conventionally recognised second-order Doppler shift – has been revealed in a series of recent Mössbauer experiments, where a radioactive source is fixed at the centre and an absorber is attached to the rim of the rotating disc. This disclosure gives indication to a possible violation of the “clock hypothesis” by Einstein: i.e. the independence of the rate of a clock on its acceleration. At the moment, there seem to be two plausible interpretations of this result: (i) the deviation of the geometry of the rotating disc from that predicted by the general theory of relativity (GTR), or (ii) the existence of a specific maximal acceleration in nature, when transformation between two accelerated frames differs from the corresponding transformation of the relativity theory. We take a closer look at both ways leading to the violation of the clock hypothesis; particularly, by analysing the outcomes of recent experiments in rotating systems and by suggesting a new Mössbauer rotor experiment to determine the most feasible mechanism for testing the dependence of the rate of a clock on its acceleration.
Modeling Type-1 Singleton Fuzzy Logic Systems Using Statistical Parameters in Foundry Temperature Control Application
Authors: Montes-Dorantes Pascual Noradino , Santoyo Adriana Mexicano , Méndez Gerardo Maximiliano 
Published: November 2018

Abstract
This article presents a novel methodology to model a type-1 singleton fuzzy logic system (T1 SFLS) for temperature prediction in a secondary metallurgical process that takes place inside a ladle furnace. The proposal generates approximations using the energy consumed and the time elapsed within the casting process as input data, without using other instruments. It is known that the temperature cannot be verified all the time in the ladle furnace because it is sealed when it is in operation, and when temperature is measured, there is an uncertainty level in the sensor reading that generates predictions of the temperature in the order of 2.5 % out of the real value. The three proposed methodologies for the T1 SFLS forecaster provide a more accurate approximation of the temperature with less than 1 % of uncertainty. The predicted temperature is used in decision making to generate the required chemical composition of the steel and to mark the appropriate times to aggregate the additives in the alloy and achieve the required chemical balance. Compared with the model used by the industry, the results obtained show that the use of the proposed fuzzy model gives the opportunity to increase the quality of the steel by improving the adjustment of the quantities of additives that are lost by oxidation.

Published: November 2018

AbstractLight-sheet microscopy (LSM) has proven a useful tool in neuroscience to image whole brains with high frame rates at cellular resolution and, in combination with tissue clearing methods, is often employed to reconstruct the cyto-architecture over the intact mouse brain. Inherently to LSM, however, residual opaque objects, always present to some extent even in extremely well optically cleared samples, cause stripe artifacts, which, in the best case, severely affect image homogeneity and, in the worst case, completely obscure features of interest. Here, demonstrating two example applications in intact optically cleared mouse brains, we report how Bessel beams reduce streaking artifacts and produce high-fidelity structural data for the brain-wide morphology of neuronal and vascular networks. We found that a third of the imaged volume of the brain was affected by strong striated image intensity inhomogeneity and, furthermore, a significant amount of information content lost with Gaussian illumination was accessible when interrogated with Bessel beams. In conclusion, Bessel beams produce high-fidelity structural data of improved image homogeneity and might significantly relax demands placed on the automated tools to count, trace, or segment fluorescent features of interest.

Los videos empleados son de propia autoría y todos se encuentran de forma libre en YouTube.
Dar voz a los protagonistas: La participación estudiantil en el proceso de enseñanza-aprendizaje
Authors: Hidalgo Nina , Perines Haylen 
Published: November 2018

El objetivo principal de este artículo es describir las prácticas pedagógicas y las actitudes que docentes tienen hacia la participación de estudiantes. Para ello, se ha desarrollado un estudio ex post facto descriptivo con 177 docentes pertenecientes a centros de Educación Secundaria de cuatro comunidades autónomas de España. La investigación se centra en tres aspectos de las prácticas de participación que desarrollan el personal docente: la selección del contenido a enseñar, las estrategias didácticas a llevar a cabo y la evaluación de los aprendizajes. Los resultados apuntan a que estos cuerpos permiten que sus estudiantes participen principalmente en la selección de las estrategias didácticas; pero muy poco en la evaluación o en la selección de los contenidos. Además, entre las tres prácticas de participación analizadas la opción más elegida por el profesorado es informar al alumnado con antelación de lo que se va a realizar. Por otro lado, muy poca cantidad de docentes afirma dar espacio al consenso o a la implicación de estos.
The dark side of internet: Preliminary evidence for the associations of dark personality traits with specific online activities and problematic internet use
Authors: Kircaburun Kagan , Griffiths Mark D. 
Published: November 2018

Background and aims
Research has shown that personality traits play an important role in problematic internet use (PIU). However, the relationship between dark personality traits (i.e., Machiavellianism, psychopathy, narcissism, sadism, and spitefulness) and PIU has yet to be investigated. Consequently, the objectives of this study were to investigate the relationships of dark traits with specific online activities (i.e., social media, gaming, gambling, shopping, and sex) and PIU.

Methods
A total of 772 university students completed a self-report survey, including the Dark Triad Dirty Dozen Scale, Short Sadistic Impulse Scale, Spitefulness Scale, and an adapted version of the Bergen Facebook Addiction Scale.

Results
Hierarchical regression analysis and a multiple mediation model indicated that being male was positively associated with higher online gaming, online sex, and online gambling, and negatively associated with social media and online shopping. Narcissism was related to higher social media use; Machiavellianism was related to higher online gaming, online sex, and online gambling; sadism was related to online sex; and spitefulness was associated with online sex, online gambling, and online shopping. Finally, Machiavellianism and spitefulness were directly and indirectly associated with PIU via online gambling, online gaming, and online shopping, and narcissism was indirectly associated with PIU through social media use.

Discussion
Findings of this preliminary study show that individuals high in dark personality traits may be more vulnerable in developing problematic online use and that further research is warranted to examine the associations of dark personality traits with specific types of problematic online activities.
Treatment efficacy of a specialized psychotherapy program for Internet Gaming Disorder
Authors: Torres-Rodríguez Alexandra , Griffiths Mark D. , Carbonell Xavier , Oberst Ursula 
Published: November 2018

Background and aims
Internet Gaming Disorder (IGD) has become health concern around the world, and specialized health services for the treatment of IGD are emerging. Despite the increase in such services, few studies have examined the efficacy of psychological treatments for IGD. The primary aim of this study was to assess the efficacy of a specialized psychotherapy program for adolescents with IGD [i.e., the “Programa Individualizado Psicoterapéutico para la Adicción a las Tecnologías de la Información y la Comunicación” (PIPATIC) program].

Methods
The sample comprised 31 adolescents (aged 12–18 years) from two public mental health centers who were assigned to either the (a) PIPATIC intervention experimental group or (b) standard cognitive-behavioral therapy (CBT) control group. The interventions were assessed at pre-, middle-, and post-treatment phases, as well as a 3-month assessment was carried out after completing the interventions.

Results
No significant differences between either group in the pre-treatment phase were found. Relating to the different interventions examined, significant differences were found at pre-test and post-test on the following variables: comorbid disorders, intrapersonal and interpersonal abilities, family relationships, and therapists’ measures. Both groups experienced a significant reduction of IGD symptoms, although the PIPATIC group experienced higher significant improvements in the remainder of the variables examined.

Discussion and conclusions
The findings suggest that PIPATIC program is effective in the treatment of IGD and its comorbid disorders/symptoms, alongside the improvement of intra- and interpersonal abilities and family relationships. However, it should also be noted that standard CBT was also effective in the treatment of IGD. Changing the focus of treatment and applying an integrative focus (including the addiction, the comorbid symptoms, intra- and interpersonal abilities, and family psychotherapy) appear to be more effective in facilitating adolescent behavior change than CBT focusing only on the IGD itself.
