Golden age divas on the silver screen: Challenging or conforming to dominant gender norms?
Authors: Abdel-Fadil Mona , Van Eynde Koen
Published: June 2016

Egyptian cinema has been hugely influential throughout the Arab world, and has produced several divas. Fatin Hamama (d. 2015) and Soad Hosny (d. 2001) were very popular among their contemporaries and still continue to enchant audiences. Yet, there has been little systematic study of the cinema roles such enthralling divas were cast in. In this article, we discuss the genre melodrama, and the roles played by these two highly successful Egyptian actresses and stars over decades. We ask: to what degree do Fatin Hamama and Soad Hosny’s iconic screen characters conform to or challenge dominant gender norms? We broaden our inquiry so as to examine what characterizes the gender dynamics in the films that Fatin Hamama and Soad Hosny star in, thereby exploring what kind of male characters they are pitted against and how the gendered power dynamics play out in the storyline. The films we analyse, illustrate how numerous themes and narratives on class, patriarchy, education, modernity and nationalism overlap and play into the definition of power and relations across both class and gender. Against the backdrop of a highly politicised cinema, we discuss the various ‘state narratives’ or counter-narratives that appear to be informing the films, and demonstrate how productions from the 1950s, 1960s or 1970s betray wider political sentiments of their time. We argue that Fatin Hamama and Soad Hosny’s screen choices and famous stage personae developed in line with the capacity of the national modernist project to produce the desired results on the ground.
Religion and individual civil rights: Moroccan Jewish citizens in Where Are You Going Moshe?
Authors: Elkabas Charles
Published: June 2016

For decades, questions about Jewish mass emigration from Morocco were never discussed openly, and it is only in the last few years that historians, writers, politicians and film-makers have turned their attention to this delicate subject by debating it in a public forum. While we use Hassan Benjelloun’s light-hearted film Where Are You Going Moshe? (2007) as a starting point to review questions of religion, identity and citizenship, we propose that Moroccan Jews left their country en masse because they were deprived of their mobility rights.
Framing the Libyan uprising: A comparison between Al Jazeera Arabic’s and BBC Arabic’s coverage of the 2011 uprising and ensuing NATO intervention
Authors: Al Nahed Sumaya
Published: June 2016

This article compares Al Jazeera Arabic’s and BBC Arabic’s news coverage of the 2011 Libyan uprising and the ensuing NATO intervention in the country. Through this comparative analysis, the article evaluates the impact of these two channels’ political contexts on their coverage, especially considering that these two channels are part of broader transnational news networks that are based in countries that were active participants in the NATO intervention in Libya. The sample involves a period of roughly four weeks of coverage, and considers aspects such as the birth of the February 17 movement in Libya, the development of the opposition, the beginning and end of the 2011 NATO mission and the death of former Libyan leader Muammar Gaddafi. The sample was analysed by means of a framing analysis, whereby framing refers to the way a news story is packaged, and is an especially appropriate method when considering the influence of political power on coverage. The comparative analysis ultimately found that both channels’ coverage was primarily affected by their political contexts, and aligned with national and foreign policy interests of their home countries. This alignment was evident through the coverage that was supportive of the opposition and its advances, and the intervention and its gains. However, BBC Arabic’s coverage was more balanced, especially with regard to the progression of the opposition on the ground, as it did not play up opposition gains or gloss over opposition losses, as Al Jazeera Arabic tended to do. BBC Arabic also displayed a more analytical stance when covering the death of the former Libyan leader Muammar Gaddafi. The language used by Al Jazeera Arabic was also far more emotive and sensationalistic than that of BBC Arabic, which displayed a far more tempered stance when covering the Libyan uprising. Thus, this article also considers how each of these channels used the Arabic language when reporting, and how these stylistic differences might have affected their coverage.
Exclusion in the Canadian context: Full-face veils as a barrier to citizenship
Authors: Mazurski Lara
Published: June 2016

This article explores the fiery debate on the prohibition that restricted women in fullface veils from participating in citizenship and oath-taking ceremonies in Canada (2011–2015). It shows that one of the most salient elements in this debate was limiting access to the possibilities of acquiring citizenship for veiled women and the communities they represent. Utilizing a combination of post-colonial theory, ideas of deliberative democracy, and agonistic pluralism I explore the production of discourses that scapegoat veiled women as a threat to the imagined ideal of national identity and which situate full-face veils and the women who wear them as a threat to the Canadian political sphere. After reviewing the interdisciplinary literature surrounding this debate the article concludes with a discussion of how this prohibition works against the very ideals of pluralism.
The rock star figure: Authenticity, satire and legacy in Bloody Bloody Andrew Jackson (2006)
Authors: Noonan Julie A.
Published: June 2016

This article argues that the rock star figure trope found in some rock musicals illustrates bigness by mirroring mechanisms of rock star construction and projecting a connection to the musical audience. In doing so, the article discusses the rock star figure as a character trope utilizing theories of mediated ‘personas’ and rock authenticity. It uses the rock star figure in Bloody Bloody Andrew Jackson (2006) to explore the extension of an onstage crowd that invites the audience into a vicarious connection with Jackson’s historical legacy. When the rock star figure is modelled on an historical figure, the audience member’s role is extended for them to negotiate their interpretation of the character’s historical legacy within contemporary circumstances. In Bloody Bloody Andrew Jackson, satire, irony and emulation of emo-rock style are layered onto the rock star figure to implicate the audience in contemporary events.
Las migraciones internacionales y la reorganización de los cuidados. Los casos de la República de Moldavia, Rumanía y Ucrania
Authors: Alice Vianello Francesca
Published: June 2016

En el contexto de los importantes flujos migratorios desde Europa del Este hacia Europa Meridional, en este artículo se presenta un estudio cualitativo realizado en Rumanía, la República de Moldavia y Ucrania en torno a la reorganización de los cuidados que se requieren para afrontar las repercusiones de la ausencia de personas cuidadoras, también conocida como «drenaje de cuidados». En particular, se analiza la reorganización de los cuidados destinados a los menores y a las personas mayores que se quedaron en los países de procedencia tomando en cuenta los cuatro pilares del sistema o polos del «diamante» de los cuidados, a saber: las familias transnacionales, el Estado, el tercer sector y el mercado. La perspectiva desde los países de origen, la comparación entre el sistema de cuidados infantil y el dirigido a los mayores, así como la inclusión del Estado y de la sociedad civil como proveedores de cuidados complementarios a los de las familias, ofrecen una visión más completa de las trasformaciones sociales generadas por la emigración masiva.
Análisis comparativo de políticas autonómicas de España para la emigración y la ciudadanía en el exterior, 1983-2012
Authors: Oiarzabal Pedro , Uzcanga Catalina , Bartolomé Edurne
Published: June 2016

Actualmente más de dos millones de españoles residen oficialmente en el extranjero. Desde 1980, tanto el gobierno central como los autonómicos han implementado paulatinamente una pléyade de políticas con el objetivo de reconocer y apoyar a sus poblaciones emigrantes. El presente artículo se adentra en el análisis comparativo y evolutivo del marco legislativo, de las estructuras administrativas, de los servicios y presupuestos dedicados a la emigración, y que han sido desarrollados por el gobierno central y por diez de las Comunidades Autónomas con mayor volumen de población en el exterior. La investigación se complementa con entrevistas a los gestores y políticos autonómicos con responsabilidad en materia emigratoria. El estudio vislumbra la urgente necesidad tanto de colaboración entre administraciones públicas, como de reactualización de las políticas de emigración en un contexto de crisis económica, pérdida de población y aumento de la emigración.

Published: June 2016

A pesar del momento de crisis, Europa fortalece cada día su dimensión como comunidad internacional y ha creado un modelo de crecimiento y cohesión que puede ser una referencia para otros contextos. Una clave para lograr los objetivos de integración europea es el consenso en las decisiones sobre educación y específicamente en la implementación de las diversas acciones de movilidad Erasmus que desde 1987 ha implicado a 3 millones de personas. Esta investigación analiza este programa en la Universidad de Oviedo. Partimos de una descripción de los intereses que llevan a estas personas a iniciar la movilidad y constatamos que produce especial motivación la vivencia de una experiencia internacional, así como los factores académicos y culturales. A esto se suma el interés por dominar un segundo idioma y explorar las opciones laborales. Los resultados globales de esta singular migración en la mayoría de los casos reafirman una valoración del periodo como bueno o excelente.

La penalización de los migrantes: irregularidad y cárcel en la construcción del estado neoliberal
Authors: González Sánchez Ignacio
Published: June 2016

En el presente artículo se analizan los procesos punitivos que afectan de una manera notable a las personas extranjeras en España. Tras una breve contextualización del proceso migratorio, y de su problematización en términos relacionados con la inseguridad y la delincuencia, se presta atención a dos formas de penalización: la administrativa, vinculada a las leyes de extranjería, y la penal, reforzada por la situación precaria de estos colectivos. Posteriormente se analizan sus efectos materiales –relacionados con el mercado laboral-, simbólicos –en las categorizaciones sociales- y disciplinarios –en la conformación de subjetividades-. Se defiende la pertinencia de estudiar los procesos de penalización para vislumbrar dinámicas sociales más amplias y la pertinencia de dar mayor importancia a estos procesos en los estudios sobre las personas migrantes.
Quality and Safety Assurance of Iron Casts and Manufacturing Processes
Authors: Kukla S.
Published: June 2016

The scope of this work focuses on the aspects of quality and safety assurance of the iron cast manufacturing processes. Special attention was given to the processes of quality control and after-machining of iron casts manufactured on automatic foundry lines. Due to low level of automation and huge work intensity at this stage of the process, a model area was established which underwent reorganization in accordance with the assumptions of the World Class Manufacturing (WCM). An analysis of work intensity was carried out and the costs were divided in order to identify operations with no value added, particularly at individual manufacturing departments. Also an analysis of ergonomics at work stations was carried out to eliminate activities that are uncomfortable and dangerous to the workers' health. Several solutions were proposed in terms of rationalization of work organization at iron cast after-machining work stations. The proposed solutions were assessed with the use of multi-criteria assessment tools and then the best variant was selected based on the assumed optimization criteria. The summary of the obtained results reflects benefits from implementation of the proposed solutions.
Repair of Structural Steel Surface Groove by Using Diffusion Welding of Pure Iron Powder
Authors: Rahimy Y. , Vahdat S.E.
Published: June 2016

Metal pieces wear out due to variable loading, because cracks formed on their surface of them. In order to increase useful life of metal pieces with the help of different methods of welding, surface cracks are repaired. In this research, performance of the diffusion welding of pure iron powder through magnetic induction evaluated for repairing structural steel surface cracks. First, four specimens prepared including one control specimen and other three specimens grooved specimens in length of 6.25mm and in depth of 1mm and groove width in the sizes of 0.5, 0.75 and 1mm. Then by a coil, the induced current created in the piece surface. After crossing the current, the powder melted and the groove repaired due to diffusion welding. To prevent oxidation, the atmosphere inside the coil filled with argon gas. The results show that after repairing surface groove, tensile strength of the repaired specimens reached to the tensile strength of control specimen with the margin of 7.5%.

Published: June 2016

Truck drivers are one of the largest occupational groups in Iran. Evidence from previous studies suggests that working and living conditions on the road engender many concerns for truck drivers, and their families and communities. This research aimed to explore the experiences of Iranian truck drivers regarding life on the road.

This qualitative study was conducted among Iranian truck drivers working in the inter-state transportation sector. A purposeful sample of 20 truck drivers took part in this research. Data were collected through semi-structured interviews and analyzed based on qualitative content analysis.

After analysis of the data, three main themes emerged: “Individual impacts related to the hardships of life on the road life”, “Family impacts related to the hardships of road life”, and “Having positive attitude towards work and road”. These findings represent the dimensions of perspectives in the road-life of truck drivers.

Although truck drivers possess positive beliefs about their occupation and life on the road, they and their families face many hardships which should be well understood. They also need support to be better able to solve the road-life concerns they face. This study's findings are useful for occupational programming and in the promotion of health for truck drivers.

Published: June 2016

Polymerization contraction of composite resins has been one of the most extensively studied phenomena in dentistry in recent years. Initial polymerization by low intensity light followed by polymerization high intensity light improves marginal adaptation of composite in tooth cavities. A number of studies have verified that less marginal leakage and lower marginal index (MI) exist in relation to standard polymerization (continuous high intensity light).

The aim of the study was to quantittively evaluate the bond of composite materials to dentin and determine the MI values in dentin after the application of two techniques of light polymerization in two composite systems.

Twenty V class cavities were restored on extracted teeth for scanning electron microscopic (SEM) analysis of composite to dentin junction. Adhesion to dentin was achieved using Adper Single Bond 2-ASB/3MESPE, that is, Adper Easy One-AEO/3MESPE. Light polymerization of composite materials Filtek Ultimate-FU/3MESPE was performed using standard halogen light (HIP) or soft start program (SOF).

Marginal index of dentin was determined by measuring the length and width of marginal gap at the junction of composite filling to dentin, using scanning mirographies and Autodesk AutoCAD program.

Two-way ANOVA test was used for statistical processing of the obtained results. Differences in MI index between different light polymerization techniques (HIP- 8,18 and SOF-7,12) were not statistically significant (p>0,05), while the differences between composite systems (ASB/FU- 3,67 i AEO/FU- 7,69) were statistically significant (p <0.05).

The polymerization technique showed no significant effect on the composite to dentin junction. Lower MI dentin was established in composite system with the application of adhesive etch and rinse procedure in both polymerization techniques.

Authors: Malaga-Toboła Urszula , Tabor Sylwester , Kwaśniewski Dariusz , Kuboń Maciej
Published: June 2016

Production capacity is the amount of production with the determined assortment structure possible to achieve by a particular production unit in a determined time at the optimal use of production factors and at maintaining the products quality corresponding to standards. The objective of the paper was to determine the production power and output of particular workstations which constitute an assembly line of dry animal feed. The scope of research covered an assembly line in the establishment which produces dry feed for pet animals. Based on information and documentation obtained from the company manager and on the work schedule determined for particular workstations, the operation time of a machine, human work time (operation of a machine) and operation time of the entire station with its working surface was determined. Research showed that workstations which constituted the assembly line of dry animal feed were loaded within 76 to 86%. The lowest loading was reported in the mill and LP02 assembly line and it was respectively 76 and 78%. Whereas loading of the remaining devices was comparable and was at the level within 84 to 86%.

Authors: Pieczarka Krzysztof , Kierdal Mateusz , Lejman Krzysztof , Owsiak Zygmunt
Published: June 2016

The research concern selected traction properties of Massey Ferguson 7475 wheeled tractor, which were carried out on various deformable surfaces i.e. soil: after ploughing, sodded and with rye fore crop. The impact of driving speed on tractive power and force with 2WD and 4WD drive was investigated. Physical and chemical properties of soil during testing were characterised by moisture, compactness and maximum shearing stresses. Studies on traction properties were carried out with the use of two tractors: Massey Ferguson 7475 and New Holland 5040. During measurements, tractors were connected with a tow rod, where a strain force transducer was mounted. The stand enabled also measurement of theoretical speed. As a result of analyses of the obtained results, characteristics of tractive force and towing power as a function of slip were made. The tests confirmed that the use of four-wheel drive is unjustified because it improves these tractive parameters of a tractor. It was reported that the maximum force and towing power are generated for the lowest values of slip which is equal to 0.1 on the sodded surface. However, value of this power is the lowest in comparison to other surfaces. The highest value of the adhesion coefficient was reported on soil with rye fore crop.
Usefulness of the measurement of saccadic refixation in the diagnosis of attention-deficit hyperactivity disorder/hyperkinetic disorder in adults
Authors: Walecki Piotr Krzysztof , Gorzelańczyk Edward Jacek
Published: June 2016

Background:

The aim of the research is to evaluate the usefulness of the measurement of saccadic refixation in the diagnosis of attention-deficit hyperactivity disorder (ADHD)/hyperkinetic disorder (HKD) in adults.

Methods:

Seventy-eight individuals were examined: 40 with ADHD/HKD and 38 healthy ones. A noninvasive eye movement examination using the Saccadometer (Advanced Clinical Instrumentation, Cambridge, UK) was applied. Two saccadic tests, prosaccades task (PT) and antisaccades task (AT), were carried out.

Results:

Based on the results, we can assume that selected parameters, such as latency, standard deviation of latency, promptness, and correctness (directional errors), in individuals with ADHD/HKD differ statistically in the relevant parameters from the healthy ones. The latency and the standard deviation of latency in ADHD/HKD participants are greater when compared to healthy ones. ADHD/HKD participants have a greater number of directional errors in comparison to healthy ones.

Conclusions:

The standard deviation of latency prosaccades is a good parameter for distinguishing people from both groups. An important and innovative solution in this study in comparison to the studies of other authors, who reached similar results, is the use of an automatically calibrating system (autonomous) adapted for clinical use as well as a quantitative analysis of the saccadic parameters.
Report on the magnetic survey in Slovakia for the 2014.5 epoch
Authors: Valach Fridrich , Váczyová Magdaléna , Šoltis Tomáš , Vajkai Melinda
Published: June 2016

The models of the distribution of the elements of the geomagnetic field must be updated regularly. For this purpose geomagnetic measurements have to be carried out repeatedly at geomagnetic observatories as well as at temporary observation points. In this paper the results of the geomagnetic survey that was carried out in Slovakia in the year 2014 are presented. The measurements were performed at 12 observation points and they were reduced to the 2014.5 epoch. The secular variation between 2007.5 and 2014.5 was also calculated. The obtained values of the geomagnetic elements were used for calculating a 1st-degree polynomial model for the distribution of magnetic declination, inclination and total field. The comparison with the IGRF model showed that the polynomial model provided more accurate results for magnetic inclination and total field. For magnetic declination, on the contrary, the IGRF model produced slightly better results than the polynomial model.
Effect of integrated Yoga and Physical therapy on audiovisual reaction time, anxiety and depression in patients with chronic multiple sclerosis: a pilot study
Authors: Chobe Shivaji , Bhargav Hemant , Raghuram Nagarathna , Garner Christoph
Published: June 2016

Background: Multiple sclerosis (MS) is characterized by a significant deterioration in auditory and visual reaction times along with associated depression and anxiety. Yoga and Physical therapy (PT) interventions have been found to enhance recovery from these problems in various neuropsychiatric illnesses, but sufficient evidence is lacking in chronic MS population. The aim of this study was to assess the effect of integrated Yoga and Physical therapy (IYP) on audiovisual reaction times, depression and anxiety in patients suffering from chronic MS.

Methods: From a neuro-rehabilitation center in Germany, 11 patients (six females) suffering from MS for 19±7.4 years were recruited. Subjects were in the age range of 55.45±10.02 years and had Extended Disability Status Scores (EDSS) below 7. All the subjects received mind–body intervention of integrated Yoga and Physical therapy (IYP) for 3 weeks. The intervention was given in a residential setup. Patients followed a routine involving Yogic physical postures, pranayama, and meditations along with various Physical therapy (PT) techniques for 21 days, 5 days a week, 5 h/day. They were assessed before and after intervention for changes in audiovisual reaction times (using Brain Fit Model No. OT 400), anxiety, and depression [using Hospital Anxiety and Depression Scale (HADS)]. Data was analyzed using paired samples test.

Results: There was significant improvement in visual reaction time (p=0.01), depression (p=0.04), and anxiety (p=0.02) scores at the end of 3 weeks as compared to the baseline. Auditory reaction time showed reduction with borderline statistical significance (p=0.058).

Conclusions: This pilot project suggests utility of IYP intervention for improving audiovisual reaction times and psychological health in chronic MS patients. In future, randomized controlled trials with larger sample size should be performed to confirm these findings.

Instruments of Change: Late Dorset Palaeoeskimo Drums and Shamanism on Coastal Bylot Island, Nunavut, Canada
Authors: Rast Tim , Wolff Christopher B.
Published: June 2016

The only known evidence of Dorset Palaeoeskimo drum use ever documented was salvaged decades
ago along with thousands of other Late Dorset Palaeoeskimo artifacts from an eroding coastal site (PfFm-1) at
Button Point on Bylot Island, Nunavut (Figure 1) (Mary-Rousselière 1976, Taylor 1971-1972). These finds consist
of two nearly complete wooden drums and various other drum frame fragments that date to the centuries
surrounding A.D. 1000 (Taylor 1971-1972). In the spring of 2014, the authors and Lori White re-examined all
of the wood fragments recovered from Button Point, documenting the known drum pieces and discovering
nearly a dozen previously unidentified drum fragments. These fragments represent instruments in a range of
sizes, but with a consistent and uniquely Late Dorset Palaeoeskimo style that has not been identified prior
to our research. In this paper, we discuss a proposed typology of the Dorset drums and drum fragments, and
contrast their stylistic attributes with subsequent historic Inuit drum morphology in the region. We will also
discuss some of the functional aspects of how the drums were manufactured and the use of foraged coastal
resources in their construction. Finally, we offer an interpretation of the driftwood-constructed drums as part
of what we believe to be elements of Late Dorset shamanism.
Weak Law v. Strong Ties: An Empirical Study of Business Investment, Law and Political Connections in China
Authors: Zhang Wei , Li Ji
Published: June 2016

Based on a large-scale survey of Chinese entrepreneurs, our study explores how legal and political institutions influence investment decisions made by private companies. The study finds that, consistent with the conventional view, a more effective legal system is correlated with short-term general investment, and that the judiciary is important mainly because of its restraint over the state. The role of effective courts, however, diminishes when private entrepreneurs consider making long-term investment. We find a positive association between the entrepreneurs’ political backgrounds and their R&D investment, suggesting that Chinese courts, in spite of decades of reform, are not yet viewed as reliable to protect long-term private investment from expropriation, policy instability, and a hostile regulatory environment. Rather, informal political connections constitute the premise for the protection of long-term investment. We also find evidence indicating that political ties are expensive resources to accumulate and maintain, so Chinese entrepreneurs tap into them only when substantial long-term interests are at stake. The findings contribute to the literature on law and economic development.
Superposition of Solitons with Arbitrary Parameters for Higher-order Equations
Authors: Ankiewicz A. , Chowdury A.
Published: June 2016

The way in which solitons propagate and collide is an important theme in various areas of physics. We present a systematic study of the superposition of solitons in systems governed by higher-order equations related to the nonlinear Schrödinger family. We allow for arbitrary amplitudes and relative velocities and include an infinite number of equations in our analysis of collisions and superposed solitons. The formulae we obtain can be useful in determining the influence of subtle effects like higher-order dispersion in optical fibres and small delays in the material responses to imposed impulses.
Short-Term Effect of BalanceWear Therapy on Mobility in Older Adults With Mobility Limitations
Authors: Vincenzo Jennifer L. , Gibson-Horn Cindy , Gray Michelle
Published: June 2016

Background and Purpose:

Mobility limitations are prevalent among older adults and are related to falls, morbidity, and mortality. BalanceWear Therapy (BWT) improves measures of mobility among people with multiple sclerosis but has not been studied in older adults. Therefore, the purpose of this investigation was to examine the effects of BWT on measures of mobility among older adults with limited mobility.

Methods:

This study was a double-blind, randomized controlled trial of older adults recruited from senior living facilities. Adults aged 86.0 (6.1) years were randomized into a BWT, weighted orthotic (WG), group, n = 17, or a sham BWT, sham-weighted orthotic (SWG), group, n = 16. All participants wore the orthotic for 4 hours per day for 5 days. Mobility, measured by the Short Physical Performance Battery (SPPB), Timed Up and Go (TUG), gait speed (GS), and the Functional Gait Assessment (FGA), was recorded pre- and postintervention. Separate repeated analysis of variances were conducted for each variable to determine the intervention group (WG, SWG) by time (before, after) interaction effect.

Results and Discussion:

After a 5-day intervention of strategically weighted BWT intervention compared with a sham intervention, the SPPB improved 1.3 points in the WG, with no change in the SWG (P = .04). No between-group differences were observed for the TUG (P = .70), GS (P = .74), or FGA (P = .22).

Conclusion:

A short-term BWT intervention resulted in improvements in mobility on the SPPB among older adults with limited mobility.
Exploitation, Victimhood, and Gendered Performance in Rituparno Ghosh's Bariwali
Authors: Dasgupta Rohit K. , Banerjee Tanmayee
Published: June 2016

This article analyzes Rituparno Ghosh's celebrated film Bariwali (The Lady of the House, 2000). The film marks the beginnings of Ghosh's treatment of gender and sexual politics. Ghosh's earlier films Unishe April (1994) and Dahan (1997) engaged with strong female characters, but Bariwali is the first of his films to narrate the various ways in which female agency is routed through male exploitation and patriarchy. Through close readings of the characters and the visual tropes perspicaciously crafted by Ghosh, this article positions hegemonic masculinity and heteropatriarchal privilege as the exploiter within India's gendered politics. By placing the protagonist Banalata both within the feudal space as well as within the bhadralok discourse, one can trace the transition from tradition to modernity that the story represents, and in turn trace Ghosh's unique understanding of and reaction against India's prevailing social and cultural norms.
Screenings
Authors: Smith Paul Julian
Published: June 2016

FQ Columnist Paul Julian Smith traces the changes in queer Mexican cinema since the 1990s and asks: What does it mean for a film to be both queer and mainstream? Recent Mexican features with lesbian, gay, and trans themes pose this question. They are audience-friendly genre movies, either romantic comedies or thrillers, naturalistic in style, apolitical in attitude, and commercially produced in the hope of exhibition in theaters. Reaching out through social media to a queer community of viewers, they also seek to connect closely with their audience. Smith suggests that a new corpus of queer films is emerging that may be premature in rejecting the political and artistic radicalism of earlier Mexican queer cinema. The great virtue of these new queer films, however, is that they aim to connect with an audience beyond the art house that needs—in these changing, challenging times—to see this newly visible community represented on the big screen.
WNT4 mediates the autocrine effects of growth hormone in mammary carcinoma cells

Published: June 2016

The expression of Wingless and Int-related protein (Wnt) ligands is aberrantly high in human breast cancer. We report here that WNT4 is significantly upregulated at the mRNA and protein level in mammary carcinoma cells expressing autocrine human growth hormone (hGH). Depletion of WNT4 using small interfering (si) RNA markedly decreased the rate of human breast cancer cell proliferation induced by autocrine hGH. Forced expression of WNT4 in the nonmalignant human mammary epithelial cell line MCF-12A stimulated cell proliferation in low and normal serum conditions, enhanced cell survival and promoted anchorage-independent growth and colony formation in soft agar. The effects of sustained production of WNT4 were concomitant with upregulation of proliferative markers (c-Myc, Cyclin D1), the survival markerBCL-XL,the putative WNT4 receptorFZD6and activation of ERK1 and STAT3. Forced expression of WNT4 resulted in phenotypic conversion of MCF-12A cells, such that they exhibited the molecular and morphological characteristics of mesenchymal cells with increased cell motility. WNT4 production resulted in increased mesenchymal and cytoskeletal remodeling markers, promoted actin cytoskeleton reorganization and led to dissolution of cell–cell contacts. In xenograft studies, tumors with autocrine hGH expressed higher levels ofWNT4andFZD6when compared with control tumors. In addition, Oncomine data indicated thatWNT4expression is increased in neoplastic compared with normal human breast tissue. Accordingly, immunohistochemical detection of WNT4 in human breast cancer biopsies revealed higher expression in tumor tissue vs normal breast epithelium. WNT4 is thus an autocrine hGH-regulated gene involved in the growth and development of the tumorigenic phenotype.

Epidemiological studies suggest an increased fracture risk in patients taking proton pump inhibitors (PPIs) for long term. The underlying mechanism, however, has been disputed. By binding to the gastric proton pump, PPIs inhibit gastric acid secretion. We have previously shown that proton pump (H+/K+ATPase beta subunit) KO mice exhibit reduced bone mineral density (BMD) and inferior bone strength compared with WT mice. Patients using PPIs as well as these KO mice exhibit gastric hypoacidity, and subsequently increased serum concentrations of the hormone gastrin. In this study, we wanted to examine whether inhibition of the gastrin/CCK2 receptor influences bone quality in these mice. KO and WT mice were given either the gastrin/CCK2 receptor antagonist netazepide dissolved in polyethylene glycol (PEG) or only PEG for 1year. We found significantly lower bone mineral content and BMD, as well as inferior bone microarchitecture in KO mice compared with WT. Biomechanical properties by three-point bending test also proved inferior in KO mice. KO mice receiving netazepide exhibited significantly higher cortical thickness, cortical area fraction, trabecular thickness and trabecular BMD by micro-CT compared with the control group. Three-point bending test also showed higher Young’s modulus of elasticity in the netazepide KO group compared with control mice. In conclusion, we observed that the gastrin receptor antagonist netazepide slightly improved bone quality in this mouse model, suggesting that hypergastrinemia may contribute to deteriorated bone quality during acid inhibition.
Positive and negative effects of cellular senescence during female reproductive aging and pregnancy
Authors: Velarde Michael C , Menon Ramkumar
Published: June 2016

Cellular senescence is a phenomenon occurring when cells are no longer able to divide even after treatment with growth stimuli. Because senescent cells are typically associated with aging and age-related diseases, cellular senescence is hypothesized to contribute to the age-related decline in reproductive function. However, some data suggest that senescent cells may also be important for normal physiological functions during pregnancy. Herein, we review the positive and negative effects of cellular senescence on female reproductive aging and pregnancy. We discuss how senescent cells accelerate female reproductive aging by promoting the decline in the number of ovarian follicles and increasing complications during pregnancy. We also describe how cellular senescence plays an important role in placental and fetal development as a beneficial process, ensuring proper homeostasis during pregnancy.
Noción de ética profesional y responsabilidad social del contador público
Authors: Montoya García Jefferson David
Published: June 2016

La investigación ético-contable y su formalización en prescripciones normativas ha jugado un papel relevante en la regulación del ejercicio profesional del contador público, así como en sus factores comportamentales y actitudinales, los cuales se han contrapuesto a una realidad que pareciera sostener un concepto ético-moral relativo, acomodado y convencionalista de ética profesional y responsabilidad social.

Este artículo da cuenta del concepto histórico de ética, con la finalidad de contextualizar las responsabilidades del contador público desde un enfoque social en relación con la actual globalización capitalista. De este modo, el artículo busca conminar a la disciplina social contable para una justa racionalización entre el deber ser, la realidad y el ejercicio profesional, a través del planteamiento de máximas deónticas y no exclusivamente normativas que permitan justificar una contabilidad humana, justa, igual y libre en el siglo XXI.
Una aproximación a los ecosellos
Authors: Valero Zapata Gloria Milena , Vega Cabra Angela Patricia
Published: June 2016

El propósito de este artículo es presentar un acercamiento sobre los avances y definiciones de los ecosellos, desde la perspectiva del desarrollo y el consumo sostenible. Inicialmente se centra en la identificación de sus posibles impactos en los consumidores y en las empresas, y luego se desarrolla una breve conceptualización de los ecosellos en el contexto colombiano. A partir de esto se concluye que el etiquetado ecológico es una herramienta que busca cambiar los patrones de consumo actuales, a través de procesos que garantizan que los bienes y servicios adquiridos han sido evaluados con criterios que vinculan el ciclo de vida, por lo cual son más amigables con el ambiente. No obstante, no se deja de identificar la incertidumbre que esos criterios puedan generar.
El comercio internacional como multiplicador de la deuda ecológica
Authors: Santamaría Herrera Juan Camilo , Díaz Montaño Evelyn Ivonne
Published: June 2016

El comercio internacional es ecológicamente desigual, dado que los precios de los productos no equiparan los daños ambientales y sociales de su producción ni los servicios ambientales suministrados inherentemente en el intercambio. El presente documento describe las causas del denominado “efecto escala” del comercio internacional, a partir del concepto de deuda ecológica y de su identificación como multiplicador de la misma. Reconocer la creciente deuda ecológica establece una oportunidad para los países acreedores en la identificación de argumentos a favor, para contribuir en la reivindicación de la soberanía alimentaria y la negociación de la deuda externa. Con ello se busca la solidaridad internacional, la justicia social y una óptima relación entre el comercio internacional y el ambiente.
Las ideas ilustradas y el utilitarismo en la educación en Colombia

Después del proceso de liberación de España, el gobierno de los criollosvio la necesidad de modernizar el Estado, con el fin de superar el atrasoy los males del sistema colonial. Los dirigentes de la nación recurrieron asistemas filosóficos y autores que permitieran el cambio. El principal objetivoera modernizar la educación, influenciada por la escolástica, y se pensó enretomar las ideas de la ilustración europea ya que ésta había dado buenosresultados con la expedición botánica y las propuestas y planes educativosgiraron en torno a las ideas ilustradas españolas.Era el momento oportuno para introducir otras formas de pensar que fueranen contra de lo que España había dejado. Tal situación fue propicia parala adopción de nuevos esquemas y corrientes filosóficas procedentes delviejo continente entre cuyos representantes estaban el inglés Jeremías Benthamy el francés Destutt de Tracy. El pensamiento de los ingleses permitíaotra concepción de la vida de los hombres y de la República en diferentescampos como la educación, la economía y la política. Estos autores teníangran acogida dentro de la clase política y los intelectuales criollos quieneslos veían como los salvadores de la nueva república.

Sacralidad, tormento y rescate: la vida social de la chicha muisca
Authors: Gómez-Montañez Pablo Felipe
Published: June 2016

A la luz de las formulaciones teóricas de Appadurai y con base en fuentes históricas secundarias y datos etnográficos recogidos entre comunidades muiscas por más de siete años, este artículo estudia la chicha –o fapqua muisca– como cosa social con vida propia, cuyos significados culturales y morales se transforman en relación con los contextos históricos en los que esta bebida se enmarca, de forma tal que pasó de su primigenio sentido sagrado a ser satanizada, para luego recuperar de nuevo su sacralidad.
