Differential effects of clomipramine on depression-like behaviors induced by the chronic social defeat paradigm in tree shrews
Authors: Shen Fang , Qi Keke , Duan Ying , Li Yonghui , Liang Jing , Meng Xiaolu , Li Ming , Sui Nan
Published: September 2018

Background:

Anhedonia is a hallmark symptom in major depression that reflects deficits in hedonic capacity and it is also linked to motivation for reward. However, studies of the features of motivation in depressed tree shrews are rather sparse.

Aims:

The study aimed to investigate the core feature of depression including lack of interest, motivation reduction, and social avoidance in tree shrews. Furthermore, the effects of the treatment using clomipramine on these depression-like behaviors were assessed.

Methods:

The paradigm of chronic social defeat in tree shrews was used to evaluate the core feature of depression through examining their sucrose preference, break-point for reward, and social interaction.

Results:

The results showed that social defeat lowered the curves of the sucrose preference and the break-point, as well as decreased social interaction. The results suggested that the subordinate animals exhibited interest loss, motivational reduction, and social avoidance. After oral treatment with clomipramine (50 mg/kg/day) for four weeks, most of the depression-like behaviors were reversed, whereas the motivational reduction was not clearly affected. Notably, the motivational reduction appeared obviously during the first week after the social defeat, and the conventional tricyclic antidepressant clomipramine did not reverse the reduced motivation.

Conclusions:

These findings imply that motivational variation might be applied as a more sensitive behavioral index in subordinate animals and could furthermore be used to evaluate potential agents as antidepressants.

Published: September 2018

A study was made of the addition of a copolymer of ethylene with vinyl acetate (CEVA) on the cracking resistance of a composite based on high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE). It was shown that the introduction into the composite of a small quantity (0.5–1.5 wt%) of CEVA of certain composition in the form of its concentrate based on LLDPE leads to a significant increase in the stress cracking resistance of the composite, with retention of high physicomechanical properties.

Language Development and Epistemic Engagement Among Upper Elementary Students in Synchronous Computer-Mediated Communication
Authors: Zheng Binbin , Warschauer Mark
Published: September 2018

This study examined the synchronous computer-mediated communication of 48 fifth-grade students and their teachers in a public school for large numbers of English learners during a school year. We collected all participants’ discussion threads in the first 2 months and last 2 months of the year-long activity. Students’ language complexity was assessed through descriptive statistics and content analysis of student posts. In addition, an epistemic engagement framework using a combination of top-down and bottom-up coding schemes was developed to further examine students’ collaborative engagement in knowledge construction. The results suggest that well-designed online synchronous computer-mediated communication among linguistically diverse upper elementary students is related to increased complexity in language use and sophistication in interaction.
Vehicle crash optimization considering a roof crush test and a side impact test
Authors: Lee Youngmyung , Han Yong-Ha , Park Sang-ok , Park Gyung-Jin
Published: September 2018

The vehicle performances for the side impact test and the roof crush test are dependent on the side structure design of a vehicle. Crash optimization can be employed to enhance the performances. A meta-model-based structural optimization technique is generally utilized in the optimization process since the technique is simple to use. However, the meta-model-based optimization is not suitable for problems with many design variables such as topology and topometry optimizations. A crash optimization methodology is proposed to consider both the side impact test and the roof crush test. The equivalent static loads method is adopted for the side impact test and the enforced displacement method is adopted for the roof crush test, and the two methods are integrated. A design formulation is defined. The survival distance from the side impact test and the roof strength for the roof crush test are used for the design constraints. Crash optimization is performed for a practical large-scale structure. For conceptual design, reinforcement of the B-pillar is determined by using topometry optimization, and size and shape optimizations are employed for a detailed design to satisfy the design constraints while the mass is reduced.
In the Beginning Was the Deed: Verbal Short-Term Memory as Object-Oriented Action
Authors: Jones Dylan M. , Macken Bill
Published: September 2018

Our goal is not to present a new theory of verbal short-term memory (vSTM), but to supplant the concepts used to explain performance on vSTM tasks for some 60 years. We view the concepts of vSTM and its concomitant processes as reifications from observations of performance on these tasks. Millennia of refining, elaborating, and utilizing symbolic systems for representing the putative sounds of speech has seduced researchers into viewing verbal behavior as embodying the hallmarks of these systems, setting verbal material apart from other types of physical material with which people interact. Contrarily, we maintain that verbal material should be seen in the same light as other material. The way in which people encounter and manipulate it (e.g., in the microcosm of the vSTM setting) is to be understood with respect to processes that organize material into perceptual objects that may then be apprehended and manipulated by bodily effector systems. We outline how key empirical hallmarks of vSTM yield to this approach.
(Poli) Tickle/Prickle: Keshav Between the Lines
Authors: Venkat Vishaka , Balakrishnan Vinod
Published: September 2018

This interview with Keshav Venkataraghavan, the staff cartoonist of The Hindu, explores the principles and the profession of political cartooning. Known as Keshav, to his readers, he has been drawing for 30 years and is now the editorial consultant of The Hindu. Beginning as a caricaturist who frequented the Chennai concerts to sketch the classical Carnatic musicians, Keshav has metamorphosed into an artist-cartoonist, effortlessly switching between the austere mind devoted to art’s spirituality and the specular mind which interrogates the socio-political sphere. While Keshav has drawn attention as an artist, his style of cartooning, surprisingly, has not been examined at length. As this is the first time Keshav becomes candid about the ethics, aesthetics and profession of cartooning, the interview demands attention, especially, for an Indian perception of cartooning. The interview attempts to answer the following questions: What decides the rhetoric, ethics and aesthetics of cartooning? Why is humour significant to cartooning? What is its role in making cartoons controversial? And what distinguishes political correctness from political incorrectness? Beginning with a discussion on the intriguing language of cartooning, the interview ponders over the process of choosing ideas and creating visuals for cartooning. This conversation with Keshav helps one to understand the tightrope profession of cartooning, as a thin separation between the scathed and smooth lines that tickle and prickle targets.
Balancing Needs and Autonomy: The Involvement of Pregnant Women’s Partners in Decisions About cfDNA
Authors: Farrell Ruth M. , Mercer MaryBeth , Agatisa Patricia K. , Coleridge Marissa B.
Published: September 2018

Cell-free fetal DNA (cfDNA) screening is used to identify the presence of fetal genetic variants early in pregnancy. Patients’ informed decision-making is central to the success of this new screen in clinical practice. Although research has focused on pregnant women’s decision-making, little is known about partners’ role and preferences as a member of the decision-making dyad. Using a grounded theory approach, this study analyzed 23 in-depth interviews to examine partners’ perspectives about cfDNA screening and preferences with respect to their role in the decision-making process. Participants wished to be actively involved in testing decisions. They articulated a distinct set of needs and preferences in the decision-making process. Such involvement was hindered by several biological and logistical barriers. This study demonstrates the need to develop mechanisms that foster informed decision-making for cfDNA screening and related new reproductive genetic technologies that focus on not just the pregnant woman but also the decision-making dyad that includes her partner as well.
Drug-Coated Versus Plain Balloon Angioplasty In Arteriovenous Fistulas: A Randomized, Controlled Study With 1-Year Follow-Up (The Drecorest Ii-Study)
Authors: Björkman P. , Weselius E.-M. , Kokkonen T. , Rauta V. , Albäck A. , Venermo M.
Published: September 2018

Background and Aims:

Stenosis due to intimal hyperplasia and restenosis after initially successful percutaneous angioplasty are common reasons for failing arteriovenous fistulas. The aim of this study was to evaluate the effect of drug-coated balloons in the treatment of arteriovenous fistula stenosis.

Design:

Single-center, parallel group, randomized controlled trial. Block randomized by sealed envelope 1:1.

Materials and Methods:

A total of 39 patients with primary or recurrent stenosis in a failing native arteriovenous fistulas were randomized to drug-coated balloon (n = 19) or standard balloon angioplasty (n = 20). Follow-up was 1 year. Primary outcome measure was target lesion revascularization.

Results:

In all, 36 stenoses were analyzed; three patients were excluded due to technical failure after randomization. A total of 88.9% (16/18) in the drug-coated balloon group was revascularized or occluded within 1 year, compared to 22.2% (4/18) of the stenoses in the balloon angioplasty group (relative risk for drug-coated balloon 7.09). Mean time-to- target lesion revascularization was 110 and 193 days after the drug-coated balloon and balloon angioplasty, respectively (p = 0.06).

Conclusions:

With 1-year follow-up, the target lesion revascularization-free survival after drug-coated balloon-treatment was clearly worse. The reason for this remains unknown, but it may be due to differences in the biological response to paclitaxel in the venous arteriovenous fistula-wall compared to its antiproliferative effect in the arterial wall after drug-coated balloon treatment of atherosclerotic occlusive lesions.

Is infant belonging observable? A path through the maze
Authors: Selby Jane M , Bradley Benjamin S , Sumsion Jennifer , Stapleton Matthew , Harrison Linda J
Published: September 2018

This article evaluates the concept of infant ‘belonging’, central to several national curricula for early childhood education and care. Here, the authors focus on Australia’s Early Years Learning Framework. Four different meanings attach to ‘belonging’ in the Early Years Learning Framework, the primary being sociopolitical. However, ‘a sense of belonging’ is also proposed as something that should be observable and demonstrable in infants and toddlers – such demonstration being held up as one of the keys to quality outcomes in early childhood education and care. The Early Years Learning Framework endows belonging with two contrasting meanings when applied to infants. The first, the authors call ‘marked belonging’, and it refers to the infant’s exclusion from or inclusion in defined groups of others. The second, the authors provisionally call ‘unmarked’ belonging. Differences between these two meanings of infant belonging are explored by describing two contrasting observational vignettes from video recordings of infants in early childhood education and care. The authors conclude that ‘belonging’ is not a helpful way to refer to, or empirically demonstrate, an infant’s mundane comfort or ‘unmarked’ agentive ease in shared early childhood education and care settings. A better way to conceptualise and research this would be through the prism of infants’ proven capacity to participate in groups.
Disciplining the risky subject: a discourse analysis of the concept of resilience in social work literature
Authors: Park Yoosun , Crath Rory , Jeffery Donna
Published: September 2018

The concept of resilience has become an established, taken-for-granted concept in social work. This poststructuralist discourse analysis of randomly sampled social work articles on resilience examines the discursive mechanisms through which the concept of resilience has been constructed in particular ways and considers the political effects of such usage.

Findings

The study of resilience is always a post facto analysis; markers of resilience are predetermined by dominant ideas of the normal and the normative subject. Systemic risk factors such as poverty and inequality are acknowledged to be productive of subjects in need of resilience. Yet, those structures are relegated to the margins of the manuscript and elided in favor of individualized analysis and intervention; the identified locus of risk and the targeted site of interventions are entirely at odds. Resilience, thus, serves as a designation for risky subjects’ capacity to accommodate—not actively change—their social/political environments, including their interactions with social work and social workers. It functions as a technology of the neoliberal self that allows social workers to construct and manage subjects capable of self-management and productive self-sufficiency.

Application

The resilience enterprise thus short-circuits social work’s aims for social justice. Examination of the discourse of resilience for their implications for practice, education, and research is a political imperative for social work and is necessary to open up new sightlines of possibility for a reenergized, more complex social work praxis. Suggestions for future directions are included.
Same-sex lives between the language of international LGBT rights, international aid, and anti-homosexuality
Authors: Seckinelgin Hakan
Published: September 2018

This article considers how international development aid is used in engaging with sexuality rights in Africa. It considers both the emergence of lesbian, gay, bisexual, and transgender (LGBT) rights as aid conditionality in international aid relations and responses to these from African political leaders. The central issue identified is that political leaders for and against these rights have marginalized and ignored voices of the sexually diverse people in their engagements in African settings. Here, a problem emerges that people’s own claims for rights are subsumed within the broader agendas set by politicians at international and national levels. This article analyzes these relations and their outcomes for activists and civil society groups in diverse African settings by considering the language of LGBT rights used by international political actors and the ways in which African political leaders develop their own language on the issue.
Hilar Renal Artery Aneurysm Repair Using Coil Embolization and Covered Stent
Authors: Rodriguez-Rapale Victor A. , Martinez-Trabal Jorge L.
Published: September 2018

Introduction:

Little has been reported regarding endovascular therapy with stent of renal artery hilar aneurysms. To that end, we herein report the outcomes of 3 hilar renal artery aneurysms (RAA) treated with an endovascular technique that makes use of a covered stent and coil embolization in the repair of hilar RAA and deem using this technique is better than traditional open approach with back-table repair and autotransplatation.

Methods:

Since November 2014, 3 consecutive patients have been referred to the vascular surgery service for evaluation of a right RAA; these patients’ aneurysms were diagnosed with a CT arteriogram prior to evaluation. These patients, typically treated with open surgery, were deemed to be candidates for endovascular repair and were treated as follows: (1) cannulation of the right Common Femoral Artery with a selective arteriogram of the right renal artery, (2) covered stent to dominant hilar artery branch, and (3) coil embolization of the remaining branches/tributaries. Perioperative outcomes and quality measures were analyzed and compared.

Results:

The aneurysms were successfully covered and excluded as confirmed by a completion arteriogram. There were no perioperative morbidities (ie, acute kidney injury, endoleak, etc), and all 3 patients were discharged home the same days of their interventions. At their follow-up visits, the patients were free of symptoms and had normal renal functions as well as Computed tomography angiography (CTA) confirming successfully excluded aneurysms and no endoleaks.

Conclusion:

The technique we used demonstrated excellent outcomes with minimal comorbidities and preservation of renal function. As with many endovascular interventions, our technique compared favorably to traditional open technique in terms of technical feasibility, decreased length of stay, faster recovery, maintaining renal function, and reduced complication rates.
The Early Use of Vacuum Therapy for Penile Rehabilitation After Radical Prostatectomy: Systematic Review and Meta-Analysis
Authors: Qin Feng , Wang Shuzhen , Li Jinhong , Wu Changjing , Yuan Jiuhong
Published: September 2018

Vacuum therapy has been widely used for penile rehabilitation after radical prostatectomy (RP), but its efficacy and safety are unclear. The study was to evaluate the efficacy and safety of the early use of vacuum therapy for post-RP men. Randomized clinical trials were selected according to predefined inclusion and exclusion criteria. RevMan 5.3 software was used for meta-analyses. In total, six randomized controlled trials were included with a total of 273 post-RP patients. The meta-analysis revealed that the early use of vacuum therapy could significantly improve the five-item International Index of Erectile Function and penile shrinkage in post-RP patients. Few adverse events were reported across the included studies. This review suggests that the early use of vacuum therapy appears to have excellent therapeutic effect on post-RP patients and no serious side effects were identified. Due to overall limited quality of the included studies, the therapeutic benefit of vacuum therapy in penile rehabilitation needs be substantiated to a limited degree in the future. Better methodological, large controlled trials are expected to verify the therapeutic effect of vacuum therapy in penile rehabilitation.
Mechanisms for therapeutic effect of bulleyaconitine A on chronic pain
Authors: Xie Man-Xiu , Zhu He-Quan , Pang Rui-Ping , Wen Bing-Ting , Liu Xian-Guo
Published: September 2018

Bulleyaconitine A, a diterpenoid alkaloid isolated from Aconitum bulleyanum plants, has been used for the treatment of chronic pain in China since 1985. Clinical studies show that the oral administration of bulleyaconitine A is effective for treating different kinds of chronic pain, including back pain, joint pain, and neuropathic pain with minimal side effect in human patients. The experimental studies have revealed that bulleyaconitine A at therapeutic doses potently inhibits the peripheral sensitization and central sensitization that underlie chronic pain and has no effect on acute pain. Bulleyaconitine A preferably blocks tetrodotoxin-sensitive voltage-gated sodium channels in dorsal root ganglion neurons by inhibition of protein kinase C, and the effect is around 600 times more potent in neuropathic animals than in naïve ones. Bulleyaconitine A at 5 nM inhibits the hypersensitivity of dorsal root ganglion neurons in neuropathic rats but has no effect on excitability of dorsal root ganglion neurons in sham group. Bulleyaconitine A inhibits long-term potentiation at C-fiber synapses in spinal dorsal horn, a synaptic model of pathological pain, preferably in neuropathic pain rats over naïve rats. The following mechanisms may underlie the selective effect of bulleyaconitine A on chronic pain. (1) In neuropathic conditions, protein kinase C and voltage-gated sodium channels in dorsal root ganglion neurons are upregulated, which enhances bulleyaconitine A’s effect. (2) Bulleyaconitine A use-dependently blocks voltage-gated sodium channels and therefore inhibits the ectopic discharges that are important for neuropathic pain. (3) Bulleyaconitine A is shown to inhibit neuropathic pain by the modulation of spinal microglia, which are involved in the chronic pain but not in acute (nociceptive) pain. Moreover, bulleyaconitine A facilitates the anesthetic effect of morphine and inhibits morphine tolerance in rats. Together, bulleyaconitine A is able to inhibit chronic pain by targeting at multiple molecules. Further clinical and experimental studies are needed for evaluating the efficacy of bulleyaconitine A in different forms of chronic pain in patients and for exploring the underlying mechanisms.
How I use molecular genetic tests to evaluate patients who have or may have myelodysplastic syndromes
Authors: Steensma David P.
Published: September 2018

Myelodysplastic syndromes (MDS) can be difficult to diagnose, especially when morphological changes in blood and marrow cells are minimal, myeloblast proportion is not increased, and the karyotype is normal. The discovery of >40 genes that are recurrently somatically mutated in MDS patients raised hope that molecular genetic testing for these mutations might help clarify the diagnosis in ambiguous cases where patients present with cytopenias and nondiagnostic marrow morphological findings. However, many older healthy individuals also harbor somatic mutations in leukemia-associated driver genes, especially in DNMT3A, TET2, and ASXL1, and detection of common aging-associated mutations in a cytopenic patient can cause diagnostic uncertainty. Despite this potential confounding factor, certain somatic mutation patterns when observed in cytopenic patients confer a high likelihood of disease progression and may allow a provisional diagnosis of MDS even if morphologic dysplasia and other diagnostic criteria are absent. A subset of acquired mutations also influences risk stratification of patients with an established MDS diagnosis and can inform treatment selection. Many unanswered questions remain about the implications of specific mutations, and clinicians also vary widely in their comfort with interpreting sequencing results. Here, I review the use of molecular genetic assays in patients with possible MDS or diagnosed MDS.
STAT5 is essential for IL-7–mediated viability, growth, and proliferation of T-cell acute lymphoblastic leukemia cells

Key Points

STAT5 is required for IL-7–mediated proliferation and viability, but it does not regulate Bcl-2 downstream from IL-7 in T-ALL cells. PIM1 is required for IL-7-induced leukemia cell cycle progression and proliferation and may be a therapeutic target for IL-7-reliant T-ALLs.
Conceptual Demography in Upper Secondary Chemistry and Biology Textbooks’ Descriptions of Protein Synthesis: A Matter of Context?
Authors: Wahlberg Sara J. , Gericke Niklas M.
Published: September 2018

This study investigates how the domain-specific language of molecular life science is mediated by the comparative contexts of chemistry and biology education. We study upper secondary chemistry and biology textbook sections on protein synthesis to reveal the conceptual demography of concepts central to the communication of this subject. The term “conceptual demography” refers to the frequency, distribution, and internal relationships between technical terms mediating a potential conceptual meaning of a phenomenon. Data were collected through a content analysis approach inspired by text summarization and text mining techniques. Chemistry textbooks were found to present protein synthesis using a mechanistic approach, whereas biology textbooks use a conceptual approach. The chemistry texts make no clear distinction between core terms and peripheral terms but use them equally frequently and give equal attention to all relationships, whereas biology textbooks focus on core terms and mention and relate them to each other more frequently than peripheral terms. Moreover, chemistry textbooks typically segment the text, focusing on a couple of technical terms at a time, whereas biology textbooks focus on overarching structures of the protein synthesis. We argue that it might be fruitful for students to learn protein synthesis from both contexts to build a meaningful understanding.
Mechanical interpretation and generalization of the Cole-Cole model in viscoelasticity
Authors: Deng Wubing , Morozov Igor B.
Published: September 2018

The mechanical basis of the popular Cole-Cole rheological model in viscoelasticity is investigated by using Lagrangian mechanics with nonlinear energy dissipation. The Cole-Cole model is usually viewed as a convenient way to fit the observed frequency-dependent attenuation and velocity-dispersion spectra, but its time-domain and numerical formulations are complex and contradict standard physical principles. For example, time-domain modeling of Cole-Cole media requires special mathematical tools such as fractional derivatives, convolutional integrals, and/or memory variables. Nevertheless, we find that Cole-Cole spectra naturally arise from conventional mechanics with nonlinear internal friction (non-Newtonian viscosity). The Lagrangian mechanical formulation is applied to a finite body (a rock sample in a laboratory experiment) and a wave-propagating medium, in both cases providing rigorous differential equations of motion and revealing the time- and frequency-independent material properties. The model also leads to a generalized Cole-Cole (GCC) model with multiple internal variables (relaxation mechanisms), similar to the generalized standard linear solid (GSLS). As a practical application, the GSLS and GCC models are compared on interpretations of recent P-wave attenuation and dispersion measurements on bitumen-sand samples in the laboratory. The GSLS and GCC models can be used to predict the observed strain/stress ratios with adequate accuracy. However, each of these models offers certain advantages, which are the linearity (for GSLS) and potentially smaller number of dynamic variables and broader peaks in attenuation spectra (for GCC). Therefore, additional experiments focusing on linearity of internal friction are required to establish which of these models may be preferable for rock. The Lagrangian approach provides a simple and physically meaningful way for comparing all types of observations, formulating numerical modeling schemes, and predicting the propagation of waves and behavior of other deformations of earth media.
Structure label prediction using similarity-based retrieval and weakly supervised label mapping
Authors: Alaudah Yazeed , Alfarraj Motaz , AlRegib Ghassan
Published: September 2018

Recently, there has been significant interest in various supervised machine learning techniques that can help reduce the time and effort consumed by manual interpretation workflows. However, most successful supervised machine learning algorithms require huge amounts of annotated training data. Obtaining these labels for large seismic volumes is a very time-consuming and laborious task. We have addressed this problem by presenting a weakly supervised approach for predicting the labels of various seismic structures. By having an interpreter select a very small number of exemplar images for every class of subsurface structures, we use a novel similarity-based retrieval technique to extract thousands of images that contain similar subsurface structures from the seismic volume. By assuming that similar images belong to the same class, we obtain thousands of image-level labels for these images; we validate this assumption. We have evaluated a novel weakly supervised algorithm for mapping these rough image-level labels into more accurate pixel-level labels that localize the different subsurface structures within the image. This approach dramatically simplifies the process of obtaining labeled data for training supervised machine learning algorithms on seismic interpretation tasks. Using our method, we generate thousands of automatically labeled images from the Netherlands Offshore F3 block with reasonably accurate pixel-level labels. We believe that this work will allow for more advances in machine learning-enabled seismic interpretation.

Published: September 2018

Purpose

To investigate the effects of blood flow–restricted resistance exercise (BFRRE) on myofiber areas (MFA), number of myonuclei and satellite cells (SC), muscle size and strength in powerlifters.

Methods

Seventeen national level powerlifters (25 ± 6 yr [mean ± SD], 15 men) were randomly assigned to either a BFRRE group (n= 9) performing two blocks (weeks 1 and 3) of five BFRRE front squat sessions within a 6.5-wk training period, or a conventional training group (Con;n= 8) performing front squats at 60%–85% of one-repetition maximum (1RM). The BFRRE consisted of four sets (first and last set to voluntary failure) at ~30% of 1RM. Muscle biopsies were obtained fromm. vastus lateralis(VL) and analyzed for MFA, myonuclei, SC and capillaries. Cross-sectional areas (CSA) of VL andm. rectus femoriswere measured by ultrasonography. Strength was evaluated by maximal voluntary isokinetic torque (MVIT) in knee extension and 1RM in front squat.

Results

BFRRE induced selective increases in type I MFA (BFRRE: 12% vs Con: 0%,P< 0.01) and myonuclear number (BFRRE: 18% vs Con: 0%,P= 0.02). Type II MFA was unaltered in both groups. BFRRE induced greater changes in VL CSA (7.7% vs 0.5%,P= 0.04), which correlated with the increases in MFA of type I fibers (r= 0.81,P= 0.02). No group differences were observed in SC and strength changes, although MVIT increased with BFRRE (P= 0.04), whereas 1RM increased in Con (P= 0.02).

Conclusions

Two blocks of low-load BFRRE in the front squat exercise resulted in increased quadriceps CSA associated with preferential hypertrophy and myonuclear addition in type 1 fibers of national level powerlifters.

Published: September 2018

Apresentamos um projeto desenvolvido por um grupo de pesquisa e extensão em educação ambiental da Universidade Federal do Rio de Janeiro, que focalizou a relação de jovens com o consumo e as mediações realizadas pela escola. A partir de referenciais teóricos críticos e pós críticos sobre consumo e juventude, analisamos entrevistas de tipo grupo focal com estudantes, gestores, técnicos e docentes de uma escola pública federal do Rio de Janeiro. Os entrevistados expuseram suas visões a respeito do consumo entre jovens, relataram atividades desenvolvidas na escola e revelaram seus sonhos e práticas de consumo. Os dados produzidos geraram reflexões sobre o aspecto geracional da problemática do consumo, as identidades juvenis e as ações da escola nesse contexto. Em diálogo com pesquisas sobre juventude, defendemos que os conflitos em torno da relação juventude/consumo têm relação com a dificuldade de se considerar os jovens como sujeitos sociais, capazes de interpretar e dar sentido ao mundo.

Partindo das premissas dos estudos nos/dos/com os cotidianos, esta pesquisa de doutorado teve como objetivo pensar com imagens compartilhadas por estudantes do terceiro ano do Ensino Médio,  as noções de diferença tecidas com essa prática em suas articulações com as narrativas que engendraram. As imagens em questão foram compartilhadas na rede social da internet Facebook, em  páginas correspondentes a  grupos criados para este fim, denominados #Diferença e que operaram como dispositivo de pesquisa-intervenção, situando-se em um contexto que enunciamos como “sociedade do compartilhamento”. Buscamos pensar com fragmentos das redes de significações tecidas no momento em que eram compostas, problematizando conceitos, representações, dogmas e rupturas em relação a perspectivas tradicionais e hegemônicas da noção de diferença. As imagens, acompanhadas de suas narrativas/análises, nos deram pistas para pensar nos múltiplos atravessamentos e bricolagens entre imagens e ideias de diferença.

Published: September 2018

This study was undertaken to investigate the structural, electrical and electrochemical properties of Fe3+ substituted Mg0.55Si1.9Al0.1(PO4)3 compound synthesized by water-based sol–gel technique. X-ray diffraction showed that the compound crystallized in monoclinic crystalline phase with a space group of P1 21/c1. The sample sintered at 850 ˚C exhibited the highest conductivity of 1.42 × 10-6 S cm-1 at 373 K since it contained the highest number of mobile ions. It also exhibited the highest value of ion mobility, μ of 1.13 × 10-11 cm2 V-1 s-1 at ambient temperature which was attributed to the optimum size of migration channel as indicated by its unit cell volume. Linear sweep voltammetry result showed that the Mg0.55Si1.9Al0.1Fe0.1(PO4)3 was electrochemically stable up to 3.0 V. Meanwhile, its ionic transference number of 0.99 suggested that the majority of the mobile charge carriers were mainly to ions, expected to be Mg2+ ions.

This manuscript reports the use of TiO2-BaTiO3 composite films as a photoanode in dye-sensitized solar cell (DSSC). The influence of BaTiO3 content on the performance parameters of the DSSC has been investigated. The composite has been prepared on ITO glass substrate via sol-gel assisted with spin coating technique. The XRD analysis reveals that the sample is crystalline with the phase of BaTiO3 and anatase TiO2. From the FESEM observation, it was found that the pure sample contains bigger pores compared with the other samples prepared with various BaTiO3 contents. The samples become more compact as the content of BaTiO3 increases. The samples absorb more light in ultraviolet (UV) region than visible region. The area of absorption window varies with BaTiO3 content. The device utilizing the sample with 0 and 6 wt.% BaTiO3 demonstrated the lowest leak current. The device utilizing pure sample produced the highest η of 0.18%. This is due to this device utilized the sample with highest porosity, lowest leak current and charge transfer resistance, Rct.
Re-evaluating the use of the L1 in the L2 classroom: students vs. teachers
Authors: Tsagari Dina , Giannikas Christina Nicole
Published: September 2018

The present paper examines the effects of the monolingual and the bilingual approach in the second language (L2) classroom. The outcomes of two Likert type questionnaires and classroom observations have been employed to explore teachers’ and learners’ opinions and actions in order to evaluate how the use of the native language (L1) and the L2 is used by both learners and practitioners. Data analysis shows that there is a place for both languages and, when used in a balanced manner, they can comprise a positive cognitive effect due to the fact that the language learner actively draws in interlanguage development. The present study offers clear direction for further research as there is an evident lack of knowledge of principles of L1 use in similar EFL contexts.
Robust Prediction of Filtrate Flux for Separation of Catalyst Particles from Wax Effluent of Fischer-Tropsch Bubble Column Reactor via Regularization Network
Authors: Garmroodi Asil A. , Nakhaei Pour A. , Mirzaei Sh.
Published: September 2018

The effectiveness of an internal filtration system intended for separation of wax-catalyst from Fischer–Tropsch synthesis products is investigated in the present study. The generalization performances of in-house Regularization Network (RN) equipped with efficient training algorithm is recruited for prediction of filtrate flux. The network was trained by resorting several sets of experimental data obtained from a specific system of air/paraffin liquid phase/alumina oxide particle conducted in a slurry bubble column reactor. The RN is employed to explore the relationship between the slurry phase temperature (10–60 °C), pressure difference (0.3, 0.6 and 0.9 bar) and time (0–120 min) on the rate of outcome filtrate from various size of filter element (4, 8 and 12 microns). The superior recall and validation performances with different exemplars data points show that the optimally trained RN which has solid roots in multivariate regularization theory, is a reliable tool for prediction of filtrate flux. Faithful generalization performance of RN revels that around 66 % reduction in filtrate flux is observed by decreasing temperature from 60
{}_{}^ \circ C to10
{}_{}^ \circ C for filter pore size of 4 microns. Decreasing of slurry viscosity is the main reason of such behavior. Increasing pressure driving force has a significant effect on elevating filtrate flux. Due to cake formation, filtrate flux is decreased from 2 to 1.4 (ml/min.cm2) at constant temperature of 60
{}_{}^ \circ C for filter pore size of 8 microns. Furthermore, the backwashing process is more effective for smaller pore size filter and temperature variation does not have any considerable effect on filter recovery.

Authors: Li Jiang , Li Fuguo , An Yangyang
Published: September 2018

The hot compressive deformation behavior of pure aluminum has been investigated at different conditions of strain rate range of 0.005–10 s−1 and temperature range of 523–823 K. Based on dynamic materials model Malas criterion, processing maps were constructed to evaluate the efficiency of energy dissipation and flow instability regions. The optimized condition was around strain rate of 0.005–0.01 s−1 and temperature of 773–823 K with peak energy dissipation efficiency of 42 %. Meanwhile, the rule of strain hardening exponent, strain rate sensitivity exponent and temperature sensitivity exponent have been studied, then 3D processing maps considering the strain variable was developed, and the energy dissipation maps and the dynamic instability maps were changed with the strain increasing. Results showed that region at strain rate of 10 s−1 and the region at temperature of 823 K, strain rate of 0.005 s−1 showed high-energy dissipation rate. The 3D dynamic instability maps showed instability region of different parameters, the proper process parameters was ought to be kept away from this region. The conditions of the cracking microstructure occurred proving that the region was determined by the 3D instability maps.

Half of a Yellow Sun or the Quest for (and Repression of) New Boundaries in Post-Colonial Nigeria: An International Law Analysis
Authors: Dodo-Williams Toyin , Milano Enrico
Published: September 2018

Half of a Yellow Sun is a novel written by the Nigerian writer Chimamanda Ngozi Adichie. The title of the book takes its reference from the flag of the former, short-lived, Republic of Biafra, which consisted of a horizontal tricolour of red, black, and green, with a golden rising sun over a golden bar. The author unfolds to the reader the impact and the ugliness of the Biafran war of independence as it meanders through the lives of the interdependent main characters: Ugwu, Olanna, Kainene, Odenigbo and Richard. The events that climaxed into the civil war gradually tore apart the day-to-day routine serenity of the main characters, requiring continuous adjustment in the lives of each character to the reality of war. The harrowing experience of the war drastically changed their lives. The present contribution draws inspiration from thes novel to engage with the construction and definition of social, political and legal boundaries in post-colonial Nigeria, focussing in particular on the relevance and impact of international law norms and principles in the events that unfolded between 1967 and 1970.
Freedom’s Frontiers: The Travails of LGBT Travelers
Authors: Austin David , Wojcik Mark E.
Published: September 2018

This article considers the status of same-sex couples whose lawful marriage in one jurisdiction may not be recognized in another, or who may face discrimination and criminal penalties for their sexual orientation. The article surveys positive developments that promote equality for sexual minorities rather than their punishment. The degree of positive change varies across countries. While traveling across borders, sexual minorities are often subjected to strange dislocations in time and space: they can accelerate through centuries of struggle to find freedom in foreign lands, or they can be hurled back into the darkness of the closet or, worse, detained in a prison cell. The article also focuses on some of the positive developments – legal and otherwise – that have led to the growth of a gay tourist industry; some of the problems that gay travelers may potentially encounter when crossing into countries where the legal rights of sexual minorities are not safeguarded; and some potential “solutions” that will allow gay travelers to engage in cross-border travel without feeling that they are being forced back into the limiting borders of the closet’s confines.
Semantics of Chaos: Modernity, Law and the Commons
Authors: De Lucia Vito
Published: September 2018

The mythology of modernity is arguably premised on a double gesture of emergence from chaos. The modern subject, self-posited, constructs the world of “order” by acting as the demiurge that brings the “civilized” world into existence. At the same time he negates the chaotic materiality of nature (including the body). This mythology is an exclusionary one. All modes of possessions escaping the abstract simplicity of the modern binary of public (sovereignty) and private (property), are ideologically and materially expunged from the parameters of common sense. This article will suggest however, that chaos operates also under a different semantic configuration, namely that which is directly linked to the corporeal, unbiddable complexity of social practices. In this alternate sense, which dis-articulates the linear narrative of modern emancipation, chaos is far from a primordial, disordered state of nature in need of either a self-positing subject or a policing Leviathan. The complexity of these social practices always already contains a plurality of arrangements, which are chaotic, yet, not disordered. From the perspective of liberal and neo-liberal hegemonic legalities, these chaotic practices remain “monstrous” and a “threat to the public order,” feared as a resurgence of that corporeal materiality the modern subject has striven to forget; from the perspective of the commons however, they are resisting strategies traversing liberal modernity, and may be understood, with Foucault, as (legal) insurrections.
