Published: July 2018

Caring for an individual living with Alzheimer’s disease and other forms of dementia is especially challenging and impacts every aspect of the lives of the family caregivers. Family caregiving is defined as informal, unpaid care provided by family or friends to people with a chronic illness or disability. Caregiver burden, often experienced by a caregiver for a cognitively impaired family member, is multifaceted involving physical, psychological, social, and emotional problems. To date, little has been done to examine the relationship between the knowledge of Alzheimer’s disease and memory loss and caregiver burden. To fill this gap, a cross sectional, correlational design was employed to collect data from a convenience sample ( N = 104) of African American and Caucasian dementia family caregivers. For this study, caregivers ranged from 25 to 89 years of age with African American caregivers possessing significantly lower levels of knowledge about Alzheimer’s disease and other dementias compared to Caucasian caregivers, p < .001. There were 44 caregivers who scored 41 or greater on the Caregiver Burden Inventory corresponding to moderate to severe and higher levels of burden. Results of hierarchical multiple regression models indicated that higher levels Alzheimer’s disease knowledge was significantly associated with lower caregiver burden for all caregivers, B = −0.294, p < .01. Additionally, employment status was significantly associated with caregiver burden. This study highlights the benefits of including disease specific knowledge within educational components of dementia related interventions and programs involving families.
Pursuing “Generation Snowflake”: Mr. Robot and the USA Network’s Mission for Millennials
Authors: Smith Anthony N.
Published: July 2018

U.S. basic cable channels are increasingly directing their brands toward millennials due to the increased economic importance of this demographic group. This article contributes to scholarship on basic cable economics and scripted programming by providing insight into how the institutional prioritization of millennials is shaping commissioning and marketing strategies in the sector. Using the USA Network drama series Mr. Robot (2015–present) as a case study, it demonstrates how widespread assumptions within media culture concerning millennial viewers’ personalities, preferences, and behaviors are influencing approaches to basic cable series narrative and promotion, and—accordingly—informing channel brand identities. It argues that these assumptions are influencing channels to (1) develop brands around programming that can be perceived to have social value, (2) amplify stereotypes of millennials as “digital natives” and “snowflakes,” and (3) circulate marketing material that presumes millennials’ familiarity with online technology and deemphasizes the promotional purpose of such content.

Published: July 2018

The purpose of this multi-institutional qualitative study was to understand the educational pathways of Latino males by underscoring the unique role female family members play in their academic pursuits—through the voice of these young men. Findings demonstrate female family members were identified as being primary supporters of their educational pursuits, and actively leveraged different sources of cultural capital to help Latino males enroll and persist through postsecondary education. This study reinforces extant literature on the importance of family in the educational pathways of Latina/o students. Furthermore, it makes a unique contribution by highlighting the important role female family members hold in the Latino family as educational advocates.
Collision detection algorithm for collaborative robots considering joint friction
Authors: Xiao Juliang , Zhang Qiulong , Hong Ying , Wang Guodong , Zeng Fan
Published: July 2018

This article proposes a collision detection algorithm without external sensors that can detect potential collisions in man–robot interaction. The algorithm is based on a modified first-order momentum deviation observer that also takes friction into account. The collision detection algorithm uses joint angles, angular velocities, and torques during the detection process, without any need to consider angular acceleration. The algorithm also uses an accurate friction model that is based on a Stribeck model with second-order Fourier series compensation. The friction model is applied in advance so that compensation can be made in real time during collision detection. Identification data are filtered through a first-order low-pass filter to reduce high-frequency noise. In order to verify the algorithm, a simulation and experiment were carried out using a collaborative robot experimental platform. The results confirmed that collisions can be detected by setting appropriate threshold values. Different possible responses can be implemented according to different response strategies, with the ultimate arbiter being that collision forces are kept strictly within ordinary human tolerances. This makes sure that safety can be preserved in man–robot interaction processes.

Authors: Yi Lingzhi , Xiao Weihong , Yu Wenxin , Wang Binren
Published: July 2018

In this paper, a new six-dimensional hyperchaotic system is proposed and some basic dynamical properties including bifurcation diagrams, Lyapunov exponents and phase portraits are investigated. Furthermore, the electronic circuit of this novel hyperchaotic system is simulated on the Multisim platform, and the simulation results are agreed well with the numerical simulation of the same hyperchaotic system on the Matlab platform. Finally, a control method based on Deep Belief Network is proposed to track and control the proposed hyperchaotic system. In this method, the function of the hyperchaotic system is studied by Deep Belief Network and a high precision fitting function is obtained. Then a controller which is composed of the fitting function and the tracking reference signal is designed to achieve the tracking control of hyperchaotic systems. Simulation results verify the effectiveness and feasibility of this method.

Background

Hypertension in children is often under recognized, especially in developing countries. Data from rural areas of developing countries is particularly lacking.

Objectives

To study prevalence of hypertension and its determinants in apparently health school children from predominantly rural populations of India.

Methods

Apparently healthy schoolchildren ( n = 14,957) aged 5–15 years (mean (standard deviation) age 10.8 (2.8) years; 55.5% boys) at four predominantly rural sites in separate states of India were studied. Systolic and diastolic blood pressures were recorded by trained staff in addition to age, gender, height, weight, type of school and season. Waist circumference was also recorded in 12,068 children. Geographic location and type of school (government, government-aided or private) were used to determine socio-economic status.

Results

Systolic and/or diastolic hypertension was present in 3443 (23%) children. Systolic hypertension was present in 13.6%, diastolic hypertension in 15.3% and both in 5.9%. Isolated systolic hypertension was present in 7.7% while isolated diastolic hypertension was present in 9.4%. On univariate analysis, age, gender, geographical location, socio-economic status, season and anthropometric parameters (z-scores of height, weight and waist circumference, waist/height ratio and body mass index) were all significantly related to risk of hypertension ( p < 0.0001 for each). Similar association was observed with weight group (normal, overweight and obese). Multiple regression analysis showed lower age, female gender, richer socio-economic status, certain geographical locations, higher weight and larger waist circumference to be independently associated with a greater risk of hypertension.

Conclusion

There is a high prevalence of hypertension in apparently healthy schoolchildren even in predominantly rural areas of India. Screening and management programs targeted to high risk groups identified may prove cost-effective.

Published: July 2018

We treated four patients with severe abdominal pain in the luteal phase that showed a remarkable resemblance to dysmenorrhea. The symptoms began when the patients were in their twenties and thirties, and the pain was identical to the high phase of basal body temperature. No other abnormal findings were revealed in physical examinations, except for leiomyoma in two patients. Oral contraceptive use led to symptom exacerbation, while gonadotropin-releasing hormone agonist administration completely inhibited the pain. One patient underwent a hysterectomy for leiomyoma, with ovulation later confirmed, though luteal phase abdominal pain completely disappeared. Based on our findings, the postulated mechanism for the pain is uterine contractions induced by progesterone through various mechanisms. The symptoms in our patients were successfully treated by ovulation inhibition obtained with cyclic administration of conjugated estrogen.
Comparison of a Distal Tibial Allograft and Scapular Spinal Autograft for Posterior Shoulder Instability With Glenoid Bone Loss
Authors: Nacca Christopher , Gil Joseph A. , DeFroda Steven F. , Badida Rohit , Owens Brett D.
Published: July 2018

Background:

Posterior glenoid bone deficiency can occur with recurrent glenohumeral instability. Glenoid reconstruction with a distal tibial allograft (DTA) has been reported to successfully restore contact pressures that occur during posterior glenohumeral translation. However, there are concerns regarding the risk of allograft resorption, availability, and costs. Extracapsular reconstruction using a scapular spinal autograft (SSA) has been reported as an alternative technique secondary to its anatomic location relative to the posterior shoulder and preferable autograft properties. There are no known prior biomechanical studies evaluating the scapular spine as an effective extracapsular graft choice.

Purpose:

To compare the efficacy of a DTA and SSA in restoring the stability of a glenoid with a large posterior bone defect compared with the intact native glenoid.

Study Design:

Controlled laboratory study.

Methods:

Ten cadaveric shoulders were tested. With the use of a custom KUKA robot, a 50-N compressive force was applied to the glenohumeral joint. The peak force required to translate the humeral head beyond the glenoid lip posteriorly as well as the lateral displacement that occurred during posterior translation were measured. Testing was performed in 5 conditions: (1) intact glenoid and labrum, (2) simulated reverse Bankart lesion, (3) 12-mm posterior glenoid defect, (4) glenoid defect reconstructed with a fresh DTA, and (5) glenoid defect reconstructed with an SSA.

Results:

The mean glenoid width was 30 mm. The mean peak force and lateral displacement decreased significantly with a glenoid defect (0.99 ± 2.3 N and 0.06 ± 0.09 mm, respectively; P < .0001) compared with the intact glenoid (23.00 ± 9.7 N and 1.83 ± 0.70 mm, respectively; P = .0001). There was no significant difference between the peak force after reconstruction of the defect with a DTA (23.00 ± 7.4 N) and SSA (23.00 ± 7.7 N) when compared with the intact glenoid ( P = .9999). There were no significant differences in the peak force between the 2 grafts ( P = .9999). Additionally, both the DTA (1.04 ± 1.09 mm) and the SSA (1.02 ± 1.17 mm) demonstrated no differences in lateral displacement when compared with the intact glenoid ( P = .2336 and .2043, respectively). There was no difference in lateral displacement that occurred between the DTA and SSA ( P = .9999).

Conclusion:

Reconstruction of a large posterior glenoid defect with either a DTA or an SSA can effectively restore glenohumeral stability.

Clinical Relevance:

This study supports the use of a DTA or SSA in posterior glenoid defect reconstruction. Clinical studies are needed to determine the long-term effects of utilizing such grafts.
Endogenous Endophthalmitis: Has the Opioid Crisis Impacted the Rates and Severity of Intravenous Drug-Related Cases?
Authors: Russell Jonathan F. , Scott Nathan L. , Hinkle John W. , Yannuzzi Nicolas A. , Miller Darlene , Relhan Nidhi , Flynn Harry W.
Published: July 2018

Purpose:

Endogenous endophthalmitis is an intraocular infection associated with systemic illness and/or intravenous drug use (IVDU). Rising national rates of IVDU may have impacted rates and outcomes of endogenous endophthalmitis. The purpose of the current study is to compare rates and treatment outcomes in endogenous endophthalmitis with and without a history of IVDU.

Methods:

This is a single-center retrospective consecutive case series of 21 eyes of 17 patients with a diagnosis of endogenous endophthalmitis from May 2014 to December 2016. Clinical characteristics and treatment outcomes were compared between IVDU and non-IVDU groups.

Results:

A history of IVDU was present in 3 of 17 patients (18%), whereas the other 82% had systemic comorbidities. There was no statistically significant difference in presenting visual acuity (VA) between the IVDU and non-IVDU groups (20/630 vs 20/500, P = .75). Pars plana vitrectomy was performed at some point in the clinical course of 80% of eyes (4/5) in the IVDU group and 56% of eyes (9/16) in the non-IVDU group. Staphylococcus or Candida were the predominant causative organisms isolated in the IVDU and non-IVDU groups. Statistical analyses revealed trends towards worse last VA in the non-IVDU group compared with the IVDU group (20/1000 vs 20/110, P = .10).

Conclusions:

Compared with historical data from the same institution, there has not been an increase in the rates of IVDU-associated endogenous endophthalmitis at this tertiary referral center. VA outcomes are often poor in both groups, but there may be a better prognosis for IVDU-associated endogenous endophthalmitis.

Escolas de samba e torcidas organizadas de futebol: análise de um caso de sincretismo no carnaval paulistano
Authors: Buarque de Hollanda Bernardo Borges , Medeiros Jimmy
Published: July 2018

O presente artigo examina o processo de apropriação dos desfiles de carnaval pelas torcidas uniformizadas de futebol profissional. Trata-se de analisar o caso particular das associações de torcedores paulistanos e sua participação institucionalizada no calendário festivo da cidade de São Paulo, nas três últimas décadas. A questão central do texto interroga o fato de o carnaval ter sido apropriado pelas torcidas organizadas de São Paulo, dentro de uma estratégia jurídica e institucional de sobrevivência associativa, ante as tentativas de proibição desses subgrupos no universo do futebol pelo Ministério Público desde 1995, em razão de seu comportamento violento e socialmente antidesportivo nos estádios. Por meio de uma enquete quantitativa, procura-se compreender a simbiose dessas organizações juvenis e populares em São Paulo, com a conversão dos agrupamentos de torcedores em agremiações voltadas para a prática do carnaval. Ao final, objetiva-se entender o modo de entrada das torcidas nas ligas das Escolas de Samba, o fenômeno de sua ascensão paulatina e, em especial, a visão de parte dos atores envolvidos. Conclui-se com evidências empíricas acerca da adesão expressiva da base de integrantes das torcidas organizadas ao carnaval da cidade, trânsito que pode tanto amenizar quanto potencializar conflitos no universo futebolístico e carnavalesco.
Recusando armários: histórias de homens homossexuais no futebol brasileiro
Authors: Anjos Luiza Aguiar dos , Silva Júnior José Aelson da
Published: July 2018

No futebol, é notável entre seus participantes o exercício constante de afirmação de uma masculinidade viril para si e de uma masculinidade não viril para os adversários, enfatizando a diferenciação entre nós e eles/outros. Isso não significa que não há espaço para resistências. Nesse texto, apresentamos duas histórias de homens assumidamente homossexuais que, de diferentes modos, participam do universo do futebol. Recorremos a entrevistas de História Oral, complementadas com textos de periódicos que abordaram os grupos que tais sujeitos integraram ou integram. Suas trajetórias evidenciam experiências que vão além da exclusão e mesmo da simples tolerância, evidenciando a multiplicidade de vivências que ocorrem no contexto do futebol, algumas das quais escapam à heteronormatividade.

Published: July 2018

Mudstone formations samples from the Thessaloniki and Chalkidiki prefectures are investigated, in respect to their suitability as raw materials for the ceramic industry. In particular, the investigation concerned the determination of the mineralogical and chemical composition of the studied sample. Quartz and feldspars are the major mineralogical constituents, whereas micas, clay minerals and carbonates were detected in various amounts, follow. The samples are evaluated, concerning their suitability for ceramics production, namely majiolica, cottoforte, gre and bricks, on the basis of their chemical composition and in accordance to Si02-Al203-Fe203t, Si02 (Fe203t+K20+Na20+CaO+MgO)-(AI203+Ti02) and Fe203t-(CaO+MgO)-(K20+Na20) triangular diagrams. The general conclusion is that, most of the studied materials are unsuitable for high quality ceramics products. By contrast, some of them could be tested for the production of bricks and roofing tiles.

Published: July 2018

This paper presents the results of geological and technological research on clayey and loessoid raw materials from the continental platform of the Black Sea. The loessoid clays undergo an open - cut mining under very good technical-economic conditions and are processed in a neighbouring factory. The clay deposits from the Cobadin plateau belong to the category of silt grains with the particle sizes between 0.01 and 0.03 mm. The physic-ceramic determinations proved that the clays from the Cobadin Plateau have a good shapability as raw materials. The clay preparation and working process includes: maceration in the quarry, preparation of the material by batching and mixing, shaping, compacting, finishing, hardening. The products are dried in the Kowo type natural dryers of the factory and firing takes place in a Hoffman kiln at a temperature of 950-1000°C.

Published: July 2018

The Fe-Mn concretions are morphological features of soils under alternating oxidizing and reducing conditions. They have a high adsorption capacity for many inorganic pollutants, like heavy metals. This study determines the enrichment factors of Fe, Μη, Ni, Co, Pb and Cd in Fe-Mn concretions collected from imperfectly -drained soils in Central Greece. The data show that the concretions absorbed significant amounts of heavy metals and especially of lead and cadmium from the soil system. According to the enrichment factors, the affinity of heavy metals for the concretions due to the charged surfaces of iron and manganese oxides, follow the order Pb>Cd>Mn>Co>Ni>Fe. McKenzie (1980) also found adsorption of cobalt, manganese, nickel and lead at the same order on nine synthetic manganese oxides while Nimfopoulos et al. (1997) showed that the mobility of the metals at karst cavities enriched with Mn oxides followed the order Na>K>Mg>Sr>Mn>As>Zn>Ba>AI>Fe>Cu>Cd>Pb.

In the present study a total of sixteen samples (3 surrounding rocks and 13 uncultivated topsoils) from the industrial zone east of the city of Kavala, Northern Greece, was collected and analyzed for their content in 41 elements. The extraction of the elements was based on the digestion of 0.1 g of each sample with 2 ml HNO3 and the soil fraction used was the < 20Όμιη. The analytical methods used were ICP-OES for the elements Ca, Mg, Κ, Β, Sr, Fe, Na, Si, S, Ρ, and ΑΙ and ICPMS for the elements Mn, Zn, Cu, Ti, V, Cr, Rb, Ba, Th, La, Ce, As, Sn, Co, Se, Y, Zr, Mo, Cd, Cs, W, Sb, Li, U, Ag, Ni, Hg, Ga, Ge and Pb. The mean element concentrations of the thirteen topsoil samples were compared with the mean values for soil types Fluvisols and Leptosols. The results showed that they are enriched for the elements Ag, As and Pb by 21, 15 and 3 times, respectively. Moreover, the topsoils were compared with the three surrounding rock samples. The results showed that the concentrations of Ca, Mg, Κ, Fe, Si, S, AI, Ρ Na, Β, Ce, Co, Cs, Ga, Ge, Hg, La, Li, Mo, Ni, Rb, Se, Sn, Sr, Th, U and W in the topsoils are mainly influenced by their concentrations in the surrounding rocks. The elements Ag, As, Ba, Cd, Cr, Cu, Mn, Pb, Sb, Ti, Y, V, Zn, and Zr are enriched in the topsoils. The enrichment of Ag, As, Cd, Cr, Cu, Mn, Pb, Sb, and Zn is mainly due to the widespread presence of PBG sulphides, Mn, Cd, and As in the surrounding mineralizations. The enrichment took place, quite possibly, during the formation of Drama and Nestos basins, during Tertiary, and is possibly being continued until today. However, the human activities that take place in the area are also, at least partially, responsible for this enrichment.
THE BALKAN MOUNTAINS PALEOZOIC GOLD DEPOSITS
Authors: Mladenova V. , Kerestedjian T. , Dimitrova D.
Published: July 2018

A number of Paleozoic gold deposits are situated in the Hercynian terrains of the Balkan Mountain. On Bulgarian territory Govezhda and Svishti Plaz deposits are the most important ones. Neresnitza, Blagoev-Ka nen and Osanitza deposits are located in the Serbian part of the Balkan Mountain. All these deposits are hosted in the Pre-Alpine basement of the Balkanide zone. The orehosting structures are veins, lenses and mineralized fissures related to tension and shear faults. The structural characteristics of the ores are an evidence for tectonic control and tectonic activity during the ore deposition. All stages of ore deposition were accompanied by strong fracturing of already deposited minerals and subsequent precipitation of next portion. The economically important mineral in all these deposits is the native gold, with variable Ag contents. In the two Bulgarian deposits the main ore minerals are arsenopyrite and pyrite. Arsenopyrite is not reported for Serbian deposits, but scheelite is a main mineral there instead. Based on mineral associations, three possible genetic concepts of Au deposition could be expressed. 1) The gold is genetically associated with arsenopyrite and pyrite from stage 1 (Fe-As- Au+W). It is primarily deposited as invisible gold in these minerals. During the next stage of sulfide deposition driven by induced heating, it is remobilized and redeposited in cracks, formed during the cataclastic events of this stage. 2) The gold is genetically connected to the stage 2 (Pb-Zn-Cu-Ag- Au). 3) Dual generation of gold related to both stages 1 and 2. All Balkan Paleozoic gold deposits show lots of similarities to mesothermal gold deposits in shear zones in Archaean greenschists terrains in Canada, Western Australia and Africa, as well as to Hercynian gold deposits in France and Portugal. The similarity especially concerns their connection to granodiohtic magmatism, the mineral parageneses and the gold occurrence and its associations. Despite that the mining in the Balkan gold deposits is already closed, they still have nonexplored and non-operated reserves

Published: July 2018

Idiomorphic quartz crystals, up to 50 cm long, have been developed on massive, milky quartz substrate, within veins hosted by orthogneisses of the polymetamorphic system of the Pentelikon Mt. The veins fill NE-SW or/and NW-SE trending en-echelon fissures associated with the DfP deformation phase of Alpine age. Quartz-hosted fluid inclusions have been studied in order to decipher the physicochemical conditions of deposition and the relationship to the geotectonic evolution of the area. Homogenization temperatures (Th) to the liquid phase range between 175 and 240 °C clustering at 180-200 °C. Final ice melting temperatures (Tmjce) range between -0.1 and -14.5 °C corresponding to salinities between 0.2 and 23 wt% NaCI equiv. in the system HìO-NaCI. Thsalinity relationships indicate quartz crystallization under boiling conditions at temperatures 150-220 °C and pressures <1.5 Kbar. The results of this study indicate that quartz was deposited from hydrothermal fluids with a meteoric water component in the latest stages of retrograde metamorphism and regional decompressive uplift of the Pentelicon Mt metamorphic complex

Background:16S rRNA gene sequence analysis is a robust tool for characterization of new pathogens in clinical specimens with suspected bacterial disease. The aim of this study was to characterizePseudomonas aeruginosaisolated from clinical specimens by sequencing the 16S rRNA gene.

Methods:Forty bacterial isolates were obtained from different clinical specimens (wound, urine and sputum) using enrichment selective media and biochemical tests to characterize and identify the bacteria asP. aeruginosa.DNA was extracted fromP. aeruginosausing the Chelex method. A universal primer was used to amplify 16S rRNA genes by a conventional PCR technique. The amplified PCR products were sequenced, and the sequences were viewed by Finch TV program version 1.4.0. The identity and similarity of the nucleotide sequence of the isolated strains was detected by comparing them with published sequences using BLASTn. Phylogenetic trees were constructed using Phylogeny.fr software.

Results:Sequence analysis by BLASTn displayed high similarity and identity withP. aeruginosafrom China KX461910, Australia JN609194 and with otherP. aeruginosaisolates from the GenBank database.

Conclusions:Our observation of isolates from different origin sites, further show the utility of 16s rRNA PCR amplification. This reveals the high specify of the primers and accuracy of the PCR. Thus, 16S rRNA sequencing can be used to identify genetically atypicalP. aeruginosaisolates from different origins.

Published: July 2018

The individual development plan (IDP) is a career planning tool that assists PhD trainees in self-assessing skills, exploring career paths, developing short- and long-term career goals, and creating action plans to achieve those goals. The National Institutes of Health and many academic institutions have created policies that mandate completion of the IDP by both graduate students and postdoctoral researchers. Despite these policies, little information exists regarding how well the tool is used and whether it is useful to the career development of PhD trainees. Herein, we present data from a multi-institutional, online survey on the use and effectiveness of the IDP among a group of 183 postdoctoral researchers. The overall IDP completion rate was 54% and 38% of IDP users reported that the tool was helpful to their career development. Positive relationships with one’s advisor, confidence regarding completing training, one’s confidence about their post-training career, and a positive experience with institutional career development resources are associated with respondents’ perception that the IDP is useful for their career development. We suggest that there is a need to further understand the nuanced use and effectiveness of the IDP in general, to determine how to execute the use of the tool to maximize trainees’ career development, and to generally enhance the career development support for PhD trainees.
A função ambiental da propriedade: caráter conceitual para modulação de conflitos socioambientais
Authors: Carvalho Délton Winter de
Published: July 2018

O presente trabalho tem por escopo analisar a questão envolvendo a matéria florestal e o direito de propriedade. Sabe-se que a relação entre a proteção florestal e o direito de propriedade é extremamente complexa, pois o direito fundamental à propriedade dá ensejo ao exercício de prerrogativas inerentes ao direito subjetivo, porém este deve ser exercido respeitando outros direitos fundamentais de mesma hierarquia constitucional, como o direito ao meio ambiente ecologicamente equilibrado. Nesse sentido, será analisada a estrutura constitucional do direito de propriedade, em sua face subjetiva e objetiva. Após, será verificada a função ambiental da propriedade condiciona o direito de propriedade a garantir o caráter modulador dos conflitos entre as dimensões jusfundamentais do direito ao meio ambiente ecologicamente equilibrado e do direito à propriedade privada. A análise dos elementos semânticos e conceituais da função ambiental fornece critérios interpretativos para ponderação dos interesses em jogo, lembrando, sempre, que estes devem respeitar as premissas estruturais do Estado Constitucional.

Published: July 2018

The inorganic chemistry is one of the essential courses in the education of pre-service chemistry teachers. This study investigates the differences between the adopted learning approaches and achievements of Turkish pre-service chemistry teachers' who received the inorganic chemistry course from the same lecturer. The purposes of this study are to explore the relationship between the inorganic chemistry achievements and the adopted learning approaches of pre-service chemistry teachers and to examine the effect of their learning approaches on their inorganic chemistry achievements. This study was conducted with 127 pre-service chemistry teachers from the Department of Chemistry Education at one of the public university in Turkey. “The Study Process Questionnaire” and “The Inorganic Chemistry Achievement Exams” were used as the data collection tools. The descriptive statistics and chi-square test were used for the data analysis. The results of the study displayed that (1) there is a significant relationship between the pre-service chemistry teachers’ inorganic chemistry achievement and their learning approach; (2) their learning approach has 34 % effect on their inorganic chemistry achievements according to Somers'd value.
Collective action frames and the developing role of discursive practice in worker organisation: the case of OUR Walmart
Authors: Brett Caraway
Published: July 2018

Recent technological innovations have made possible a range of new communication practices among workers engaged in struggles to raise wages and improve working conditions. New forms of social organisation and association are changing how collective action is carried out and how collective action frames are generated. Looking at a year's worth of content from a secret Facebook group designed as a forum for current and former Walmart employees, this study considers how communication practices relate to the organisational forms of coping and resistance among workers. Analysis of the posts and comments transpiring within the group, which is loosely affiliated with the Organisation United for Respect at Walmart (OUR Walmart), suggests a growing role for personalised forms of communication in the production and circulation of collective action frames. These forms blur the distinction between discursive and strategic communication processes, requiring us to reconsider the roles traditionally played by social movement organisations and rank-and-file participants. The primary contribution of this research is to demonstrate how emerging communication practices problematise distinctions between communities of coping and of resistance, between activities that are personally satisfying and those that prioritise group concerns, and between the self-organised activities of employees and the actions of labour unions. The article concludes with a consideration of the implications of these emerging communication practices for movement outcomes.
‘I am a single mum. I don't feel like I can be as competitive as other people’: experiences of precariously employed staff at UK universities
Authors: Thomas Allmer
Published: July 2018

Universities play a central role in informational capitalism. However, higher education institutions have undergone economic, political and cultural transformations leading to competition, market orientation and new management forms. These changes have effects on many levels, including the working conditions and practices of individuals involved in the information gaining process. This article aims to find out how the existing working conditions and practices at universities form the meanings, identities and experiences of individuals by focusing on precariously employed academics. I address this question based on a theoretical analysis and qualitative interviews with casualised academic staff.
Los jóvenes y la historia: Perspectivas de estudiantes secundarios chilenos en torno al aprendizaje histórico del gobierno de la Unidad Popular y la dictadura militar
Authors: González Calderón Fabián , Gatica Villarroel Enrique
Published: July 2018

Este trabajo analiza resultados preliminares de un estudio exploratorio realizado en siete escuelas de la ciudad de Santiago de Chile. Las perspectivas de los jóvenes sobre la historia se recogieron a través de un cuestionario cerrado de 44 preguntas que respondieron 180 estudiantes de segundo año de Educación Media. La muestra incluye colegios y liceos públicos, privados y mixtos. El artículo se concentra específicamente en los resultados de dos preguntas del cuestionario, aquellas referidas, específicamente, al gobierno de Salvador Allende y la Unidad Popular (1970–1973) y al Régimen Militar instaurado en Chile a partir del 11 de septiembre de 1973. Los objetivos del estudio se orientan a conocer las narrativas históricas juveniles asociadas al aprendizaje de la historia reciente relacionando los resultados obtenidos con las memorias emblemáticas elaboradas por la sociedad chilena en referencia a este período. La perspectiva teórica desde la que se analizan los resultados releva categorías como Aprendizaje Histórico, Memoria y Narrativa concibiendo el aprendizaje de la historia como una síntesis de experiencias que superan la formación escolar.
El cine en el aula: La idea de multiperspectividad en el aprendizaje histórico: una investigación a partir de películas sobre el nazismo.
Authors: De Souza Éder Cristiano
Published: July 2018

La idea de aprendizaje histórico es un tema central para los estudios de la Educación Histórica en Brasil. Este artículo comienza por intentar definir lo que es el aprendizaje propiamente histórico a partir de un debate teórico entre ideas de Peter Lee y Jörn Rüsen. En seguida, son analizados datos de una investigación empírica sobre el aprendizaje histórico de jóvenes en el trabajo con películas, con centralidad sobre el concepto de multiperspectividad. Por fin, se concluye sobre las limitaciones de pensar el aprendizaje histórico solamente como el desarrollo de competencias conceptuales en el análisis histórico, y se apunta para un horizonte teórico en el cual se piensa que aprender Historia es también aprender a vivir.
Lecturas y libros de texto: La historia reciente en la escuela. Análisis de los manuales del nivel medio luego de la sanción de la Ley Nacional de Educación en 2006.
Authors: Acosta Juan
Published: July 2018

Este trabajo analiza cómo ha sido representado el período de la última dictadura cívico militar en algunos de los libros de textos del nivel secundario que circulan actualmente en el mercado. Para ello se tendrán presentes las renovaciones educativas producidas desde la década de los '90 hasta la última reforma con la sanción de la LEN en 2006. A su vez, se tendrá en cuenta la renovación historiográfica que se vino produciendo en los últimos años en nuestro país. Seguidamente, se analizará la estructura narrativa utilizada en los manuales para luego identificar diferencias y similitudes entre los discursos de dichos manuales en primer lugar, y en segundo lugar determinar diferencias y similitudes en los discursos con manuales de años anteriores a la sanción de la LEN. En el nivel teórico–metodológico se recuperan los aportes conceptuales del Análisis Crítico del Discurso.
Interacciones entre el estrés, el parásito y el hospedador: ¿un triángulo vicioso? (VERSIÓN EN ESPAÑOL)
Authors: BELDOMENICO Pablo , BEGON Mike
Published: July 2018

El potencial sinergismo entre la condición fisiológica del hospedador y la infección

ha sido recientemente reconocido. Aquí revisamos la evidencia que da sustento a la noción que el estrés puede jugar un papel clave en la interacción entre el hospedador y el parásito, integrando una interacción circular sinérgica de tres vías que comprende al factor estresante, las infecciones y la respuesta del hospedador: el estrés crónico desencadena respuestas que empobrecen la condición fisiológica del hospedador (incluyendo su función inmune), lo cual predispone a infecciones, lo cual resulta en más estrés, y así sucesivamente. Sostenemos que esta noción introduce capacidad adicional para explicar las ideas previas propuestas por los autores, mediante la incorporación del estrés como un tercer factor interactuante que interviene en el sinergismo entre condición e infección. A su vez, esto puede tener importantes implicancias. En la naturaleza, fuerzas evolutivas parecen remover a enfermedades relacionadas al estrés o a la virulencia exacerbada. No obstante, bajo ciertas circunstancias, los parásitos y (otros) factores estresantes interactúan generando círculos viciosos que pueden afectar la sobrevida del hospedador. A altas densidades, este se vuelve un mecanismo de regulación poblacional. Asimismo, factores estresantes antropogénicos pueden causar que este mecanismo se dispare en falso, con implicancias significativas

¿Dominación como reconocimiento distorsionado?
Authors: Abril Francisco
Published: July 2018

En el presente artículo se busca dilucidar cómo Axel Honneth aborda el problema de la dominación en Crítica del poder y La lucha por el reconocimiento. En la primera obra, el autor analiza de qué forma los sujetos sociales construyen prácticas de dominación y no se limitan a legitimarlas a posteriori. Esta concepción del dominio pone a Honneth ante el siguiente problema: ¿comprendería su planteo, además de la construcción activa de los marcos institucionales que regulan las relaciones sociales, el hecho de que los distintos grupos den asentimiento a “formas superfluas de dominación”? El primer objetivo de mi trabajo es desarrollar este problema tal y como se presenta en Crítica del poder, el segundo, apunta a retraducir esa cuestión según los términos teóricos que Honneth introduce en trabajos posteriores al hablar de una lucha por el reconocimiento. Estos trabajos buscan comprender el conflicto que se suscita en torno al reconocimiento entre los diferentes grupos sociales y del que depende que sean considerados miembros legítimos de una comunidad.

Germany’s Struggle for Energy Efficiency: Policy Instruments after the National Action Plan for Energy Efficiency (NAPE)
Authors: Weyland Matthias , Steuwer Sibyl D.
Published: July 2018

The implementation process of the German National Action Plan for Energy Efficiency (NAPE) is affected partly by considerable delay. In 2014, this plan was set up to deliver energy savings to fulfil national and European energy efficiency targets. The process shows that it takes
more time to implement innovative approaches such as the new tender scheme for energy efficiency measures. The leeway for a more ambitious implementation was limited due to economic and political barriers. But there are recommendations for the current legislation.
Parallel Numerical Creation of 2-parametric Bifurcation Diagram of Nonlinear Oscillators
Authors: Hajdu Flóra
Published: July 2018

This paper presents the numerical creation of 2-parametric bifurcation diagrams of nonlinear oscillators with a simple iterative algorithm, which can be easily parallelized. The parallel algorithm was tested with two simple well-known nonlinear oscillators, the Van der Pol oscillator and the Duffing-Holmes oscillator. It was examined how the resolution (number of iterations) affects the speedup and the efficiency. The test results show that a relative good speed up with a good efficiency could be achieved even using a simple desktop.
