A novel technique of needle setting for curvilinear endobronchial ultrasound: Improved efficiency with no cost
Authors: Meena Nikhil , Innabi Ayoub , Alzghoul Bashar , Bartter Thaddeus
Published: December 2016

Background:

Standard instructions for biopsy using the convex curvilinear endobronchial ultrasound scope include visualization and adjustment of the sheath housing the biopsy needle before every puncture. In our practice, we pre-set this relationship before inserting the endobronchial ultrasound scope and leave it fixed for every puncture.

Objective:

We postulated that this approach is more efficient than repeated re-adjustment and aimed to show that it would not increase the frequency of endobronchial ultrasound scope damage.

Methods:

Retrospective review of every biopsy using the endobronchial ultrasound scope over a 6-year period with documentation of damages and costs.

Results:

There were 15 scope damages out of 1792 procedures (0.8%). Eight damages were determined to be due to needle damage, one due to patient bite, three due to Williams airway abrasions, and three were camera failures. All damages occurred during the first 5 years of the study. Costs totaled US$138,725, for an average of US$23,120 per year. This rate of damages appears to be similar to or lower than that reported when standard instructions are followed.

Conclusion:

Pre-setting of the biopsy needle when the endobronchial ultrasound scope is used leads to greater efficiency and no increase in scope damages.

Authors: Littooij Elsbeth , Dekker Joost , Vloothuis Judith , Leget Carlo JW , Widdershoven Guy AM
Published: December 2016

After a traumatic event like a stroke, people need to find meaning and control again. This study enhances knowledge on one of the driving principles behind meaning-making processes: global meaning. Global meaning refers to individuals’ general orienting systems, comprising fundamental beliefs and life goals. Little is known about global meaning in people with stroke and whether global meaning changes after stroke. In this qualitative study, five aspects of global meaning were found: core values, relationships, worldview, identity and inner posture. Continuity in all aspects was reported, but worldview, identity and inner posture were also subjected to change.

Authors: Lockhart Tammy , Gillespie Gordon Lee , Grant Valorie
Published: December 2016

The purpose of this integrative review was to evaluate the use of text message (TM) reminders to promote timely medical surveillance examinations (MSEs). Notifying employees of scheduled MSE appointments is challenging. Text messaging can be used by occupational health nurses to remind employees of needed examinations. SCOPUS was searched for relevant studies between 2005 and 2015, resulting in nine articles meeting inclusion criteria. Seven of the nine articles reported significant improvement in attendance rates, with one study demonstrating no-show rates could be reduced by 51% using TM reminders. This integrative review demonstrated that text messaging appointment reminders for MSEs could be effective.

Authors: Gretebeck Kimberlee A. , Bailey Tatiana , Gretebeck Randall J.
Published: December 2016

Minimal contact lifestyle interventions with multiple components coupled with health screening have the potential to improve worker health. The purpose of this study was to test a minimal contact multiple component lifestyle diet and exercise intervention. The multiple components that were included in this project included a worksite health screening, brief counseling session, emailed newsletter, and a pedometer. In response to the intervention, participants reported an increase in green salad, fruit, and vegetable consumption as well as an increase in self-efficacy for consuming three servings of fruits and vegetables a day. Study participants also demonstrated a significant increase in physical activity as shown by their responses to the question, “During leisure time I walk.” A minimal contact multiple component worksite health promotion program with relatively high feasibility and low cost can improve workers’ health-related behaviors, and participants can become more aware of their health.
Effects of GO 4 IT . . . NOW! Strategy Instruction on Expository Writing Skills for Students With Disabilities
Authors: Konrad Moira , Clark Kelly A. , Test David W.
Published: December 2016

Students with disabilities trail behind their peers without disabilities while in school, as well as in post-secondary outcome areas. Given that self-determination and enhanced academic skills are associated with improved post-school outcomes, one possible solution is to identify interventions that teach self-determination and academic skills simultaneously. This study investigated the effects of GO 4 IT . . . NOW! strategy instruction on expository writing skills of five high school students with low-incidence disabilities. Using a multiple-probe-across-participants design, the authors measured the effects of strategy instruction on quality of expository paragraphs and quality and content of individualized education program (IEP) goal paragraphs. Results indicated a functional relation between the intervention and improved paragraph writing. Limitations, suggestions for future research, and implications for practice are discussed.
One for the Team
Authors: Packard Hill Esther , Fuller Glen
Published: December 2016

In the decade 2005–2015, National Rugby League players were implicated in a variety of off-field instances of violence against women. These incidents have been covered heavily by the Australian media and have facilitated commentary on violence and sport, rugby league culture, and whether rugby league players have a propensity for violence. From a total corpus of 933 articles, we critically engage with 190 news reports of domestic violence and focus on the way players and others contribute to media commentary about the incidence of domestic violence allegedly perpetrated by their teammates. Our guiding research question is: What is the character of public commentary expressed by rugby league players about incidents of domestic violence involving teammates? We identify four modes of reflexive commentary involving teammate representation that occur in the reporting of rugby league players accused of domestic violence offences. We argue that these four modes of representation articulate greater or lesser degrees of support or criticism between teammates about domestic violence and, even when critical, these discourses work to rearticulate the normative diminished reflexivity afforded men to publicly comment on and about other men.
Team Member Communication and Perceived Cohesion in Youth Soccer
Authors: McLaren Colin D. , Spink Kevin S.
Published: December 2016

Although it is assumed that athletes need to consider the member-to-member interactions that take place within a team before drawing an accurate perception about the team’s level of cohesion, little research to date has addressed this assumption. The purpose of this study was to examine the intrateam communication and cohesion relationship to determine which types of communication would be associated with perceived task and social cohesiveness in a sample of youth athletes. Youth soccer players ( N = 139, k = 13) completed measures of intrateam communication and task and social cohesion halfway through a competitive season. Separate multilevel analyses were run predicting task and social cohesion. For task cohesion, acceptance, positive conflict, and negative conflict communication emerged as significant predictors, p < .001, accounting for 40% of the total variance. For social cohesion, distinctiveness, positive conflict, and negative conflict communication were significant predictors, p < .001, accounting for 27% of the total variance. Findings provide initial evidence establishing a link between intrateam communication and cohesion in the youth sport context but more importantly suggest both similarities and differences with respect to the specific types of intrateam communication that are associated with task and social cohesion.
“Moving Toward Healthy”
Authors: Wall-Bassett Elizabeth D. , Robinson Michael A. , Knight Sharon
Published: December 2016

This study utilized participatory and potentially empowering qualitative research methods of photo-elicitation and face-to-face interviews to investigate food choices of mothers living with their children in a residential substance use disorder recovery program. Face-to-face interviews were conducted with nine women (25–40 years) living in a residential substance use disorder recovery program in the Southeastern United States. Each audio recorded and transcribed interview was coded individually before collectively developing a consensual version of the codebook and identifying themes. The recovering women in this study expressed a new or renewed desire to “eat healthy” and voiced concerns about the nutritional value of foods. Food choices were influenced by their children’s nutritional needs and food preferences, their own food preferences and habits, the financial resources available to them, their personal food preparation self-efficacy and skills, and the limitations inherent in residential recovery. Understanding food choices benefits both recovering parents and their children.

Published: December 2016

Outcomes of proactive home visit programs for frail, older people might be influenced by aspects of the caregiver–receiver interaction. We conducted a naturalistic case study to explore the interactional process between a nurse and an older woman during two home visits. Using an ethics of care, we posit that a trusting relationship is pivotal for older people to accept care that is proactively offered to them. Trust can be build when nurses meet the relational needs of older people. Nurses can achieve insight in these needs by exploring older people’s value systems and life stories. We argue that a strong focus on older people’s relational needs might contribute to success of proactive home visits for frail, older people.
The New Climate Calculus: 1.5°C = Paris Agreement, Cities, Local Government, Science and Champions (PLSC2)
Authors: Roberts Debra
Published: December 2016

The 2015 Paris Agreement is an important step forward in developing a shared and equitable global climate change response that has the possibility of limiting global temperature increase to 1.5°C above pre-industrial levels. Its long-term success, however, depends on the extent to which the goals and aspirations of the agreement (and accompanying decision text) are implemented. Cities offer a global scale opportunity to ‘bend the climate curve’ through ambitious mitigation and transformative adaptation actions. This is an opportunity that can only be realised if local governments help create a shared vision of low-carbon and climate resilient cities that improve health and well-being, provide ways to meet basic needs, create jobs, ensure environmental sustainability, foster economic opportunities and promote equity. The successful implementation of this vision requires a new type of city science that integrates natural and social sciences with grounded practice, and does not shy away from savvy politicking and passionate activism. It will also depend on champions at all levels, working across institutional boundaries to sustain action and increase momentum over time.
Predicting the recurrence of noncoding regulatory mutations in cancer
Authors: Yang Woojin , Bang Hyoeun , Jang Kiwon , Sung Min Kyung , Choi Jung Kyoon
Published: December 2016

Background

One of the greatest challenges in cancer genomics is to distinguish driver mutations from passenger mutations. Whereas recurrence is a hallmark of driver mutations, it is difficult to observe recurring noncoding mutations owing to a limited amount of whole-genome sequenced samples. Hence, it is required to develop a method to predict potentially recurrent mutations.

Results

In this work, we developed a random forest classifier that predicts regulatory mutations that may recur based on the features of the mutations repeatedly appearing in a given cohort. With breast cancer as a model, we profiled 35 quantitative features describing genetic and epigenetic signals at the mutation site, transcription factors whose binding motif was disrupted by the mutation, and genes targeted by long-range chromatin interactions. A true set of mutations for machine learning was generated by interrogating publicly available pan-cancer genomes based on our statistical model of mutation recurrence. The performance of our random forest classifier was evaluated by cross validations. The variable importance of each feature in the classification of mutations was investigated. Our statistical recurrence model for the random forest classifier showed an area under the curve (AUC) of ~0.78 in predicting recurrent mutations. Chromatin accessibility at the mutation sites, the distance from the mutations to known cancer risk loci, and the role of the target genes in the regulatory or protein interaction network were among the most important variables.

Conclusions

Our methods enable to characterize recurrent regulatory mutations using a limited number of whole-genome samples, and based on the characterization, to predict potential driver mutations whose recurrence is not found in the given samples but likely to be observed with additional samples.

Published: December 2016

Background

Liraglutide, a GLP-1 analogue, exerts several beneficial non-glycemic effects in patients with type-2 diabetes (T2DM), such as those on body weight, blood pressure, plasma lipids and inflammation markers. However, the effects of liraglutide on cardiovascular (CV) risk markers in subjects with the metabolic syndrome (MetS) are still largely unknown. We herein explored its effects on various cardio-metabolic risk markers of the MetS in subjects with T2DM.

Methods

We performed an 18-month prospective, real-world study. All subjects had T2DM and the MetS based on the AHA/NHLBI criteria. Subjects with a history of a major CV event were excluded. One hundred-twenty-one subjects (71 men and 50 women; mean age: 62 ± 9 years) with T2DM and the MetS, who were naïve to incretin-based therapies and treated with metformin only, were included. Liraglutide (1.2 mg/day) was added to metformin (1500–3000 mg/day) for the entire study. Fasting plasma samples for metabolic parameters were collected and carotid-intima media thickness (cIMT) was assessed by B-mode real-time ultrasound at baseline and every 6 months thereafter.

Results

There was a significant reduction in waist circumference, body mass index, fasting glycemia, HbA1c, total- and LDL-cholesterol, triglycerides, and cIMT during the 18-month follow-up. Correlation analysis showed a significant association between changes in cIMT and triglycerides (r = 0.362; p < 0.0001). The MetS prevalence significantly reduced during the study, and the 26% of subjects no longer fulfilled the criteria for the MetS after 18 months.

Conclusions

Liraglutide improves cardio-metabolic risk factors in subjects with the MetS in a real-world study.

Improved tomographic reconstruction of large-scale real-world data by filter optimization
Authors: Pelt Daniël M. , De Andrade Vincent
Published: December 2016

In advanced tomographic experiments, large detector sizes and large numbers of acquired datasets can make it difficult to process the data in a reasonable time. At the same time, the acquired projections are often limited in some way, for example having a low number of projections or a low signal-to-noise ratio. Direct analytical reconstruction methods are able to produce reconstructions in very little time, even for large-scale data, but the quality of these reconstructions can be insufficient for further analysis in cases with limited data. Iterative reconstruction methods typically produce more accurate reconstructions, but take significantly more time to compute, which limits their usefulness in practice. In this paper, we present the application of the SIRT-FBP method to large-scale real-world tomographic data. The SIRT-FBP method is able to accurately approximate the simultaneous iterative reconstruction technique (SIRT) method by the computationally efficient filtered backprojection (FBP) method, using precomputed experiment-specific filters. We specifically focus on the many implementation details that are important for application on large-scale real-world data, and give solutions to common problems that occur with experimental data. We show that SIRT-FBP filters can be computed in reasonable time, even for large problem sizes, and that precomputed filters can be reused for future experiments. Reconstruction results are given for three different experiments, and are compared with results of popular existing methods. The results show that the SIRT-FBP method is able to accurately approximate iterative reconstructions of experimental data. Furthermore, they show that, in practice, the SIRT-FBP method can produce more accurate reconstructions than standard direct analytical reconstructions with popular filters, without increasing the required computation time.

Published: December 2016

Botswana has the second highest population of cheetah (Acinonyx jubatus) with most living outside protected areas. As a result, many cheetahs are found in farming areas, bringing them into conflict with people. This study aimed to look at movement patterns of cheetahs in farming environments to determine whether cheetahs have adapted their movements in these human-dominated landscapes. We fitted high-time resolution GPS collars to cheetahs in the Ghanzi farmlands of Botswana. GPS locations were used to calculate home range sizes as well as number and duration of visits to landscape features using a time-based local convex hull method. Cheetahs had medium-sized home ranges compared to previously studied cheetah in similar farming environments. Results showed that cheetahs actively visited scent marking trees and avoided visiting homesteads. A slight preference for visiting game farms over cattle farms was found but there was no difference in duration of visits between farm types. We conclude that cheetahs selected for areas that are important for their dietary and social needs and prefer to avoid human-occupied areas. Improved knowledge of how cheetahs use farmlands can allow farmers to make informed decisions when developing management practices and can be an important tool for reducing human-wildlife conflict.
The anti-bat strategy of ultrasound absorption: The wings of nocturnal moths (Bombycoidea: Saturniidae) absorb more ultrasound than the wings of diurnal moths (Chalcosiinae: Zygaenoidea: Zygaenidae)
Authors: Ntelezos Athanasios , Guarato Francesco , Windmill James F.C.
Published: December 2016

The selection pressure from echolocating bats has driven the development of a diverse range of anti-bat strategies in insects. For instance, several studies have proposed that the wings of some moths absorb a large portion of the sound energy contained in a bat's ultrasonic cry; as a result, the bat receives a dampened echo, and the moth becomes invisible to the bat. To test the hypothesis that greater exposure to bat predation drives the development of higher ultrasound absorbance, we used a small reverberation chamber to measure the ultrasound absorbance of the wings of nocturnal (Bombycoidea: Saturniidae) and diurnal moths (Chalcosiinae: Zygaenoidea: Zygaenidae). The absorption factor of the nocturnal saturniids peaks significantly higher than the absorption factor of the diurnal chalcosiines. However, the wings of the chalcosiines absorb more ultrasound than the wings of some diurnal butterflies. Following a phylogenetic analysis on the character state of diurnality/ nocturnality in the Zygaenidae, we propose that diurnality in the Chalcosiinae is pleisiomorphic (retained); hence, the absorbance of their wings is probably not a vestigial trait from an ancestral, nocturnal form but an adaptation to bat activity that overlaps theirs. On a within-species level, females of the saturniids Argemma mittrei and Samia cynthia ricini have significantly higher absorption factors than the males. In the female S. c. ricini, the higher absorption factor corresponds to a detection distance by bats that is at best 20-30% shorter than that of the male.

Published: December 2016

Successful male gametogenesis involves orchestration of sequential gene regulation for somatic differentiation in pre-meiotic anthers. We report here the cloning of Male Sterile23 (Ms23), encoding an anther-specific predicted basic helix-loop-helix (bHLH) transcription factor required for tapetal differentiation; transcripts localize initially to the precursor secondary parietal cells then predominantly to daughter tapetal cells. In knockout ms23-ref mutant anthers, five instead of the normal four wall layers are observed. Microarray transcript profiling demonstrates a more severe developmental disruption in ms23-ref than in ms32 anthers, which possess a different bHLH defect. RNA-seq and proteomics data together with yeast two-hybrid assays suggest that MS23 along with MS32, bHLH122, and bHLH51 act sequentially as either homo- or heterodimers to choreograph tapetal development. Among them, MS23 is the earliest-acting factor, upstream of bHLH51 and bHLH122, controlling tapetal specification and maturation. In contrast, MS32 is constitutive and independently regulated and is required later than MS23 in tapetal differentiation.
Modulation of apical constriction by Wnt signaling is required for lung epithelial shape transition
Authors: Fumoto Katsumi , Takigawa-Imamura Hisako , Sumiyama Kenta , Kaneiwa Tomoyuki , Kikuchi Akira
Published: December 2016

In lung development the apically constricted columnar epithelium forms numerous buds during the pseudoglandular stage and subsequently changes the shape into flat or cuboidal pneumocytes that compose the air sacs during the canalicular and saccular (canalicular-saccular) stages, yet the impact of cell shapes on tissue morphogenesis remains unclear. The expression of Wnt components were decreased in the canalicular-saccular stages, and genetically constitutive activation of Wnt signaling impaired air sac formation by inducing apical constriction in the epithelium as seen in the pseudoglandular stage. Organ culture models also demonstrated that Wnt signaling induces apical constriction through the apical actomyosin cytoskeletal organization. Mathematical modeling revealed that apical constriction induces bud formation and loss of apical constriction is required for the formation of an air sac-like structure. MAP/Microtubule affinity-regulating kinase (MARK1) was identified as a downstream molecule of Wnt signaling and required for the apical cytoskeletal organization and bud formation. These results suggest that Wnt signaling is required for bud formation by inducing apical constriction during the pseudoglandular stage, while loss of Wnt signaling is for air sac formation in the canalicular-saccular stages.

Published: December 2016

Mural cells (vascular smooth muscle cells and pericytes) play a critical role in the development of the vasculature, promoting vascular quiescence and long-term vessel stabilization through their interactions with endothelial cells. However, the mechanistic details of how mural cells stabilize vessels are not fully understood. We have examined the emergence and functional role of mural cells investing the dorsal aorta during early development using the zebrafish. Consistent with previous literature, our data suggest that cells ensheathing the dorsal aorta emerge from a sub-population of cells in the adjacent sclerotome. Inhibiting recruitment of mural cells to the dorsal aorta through disruption of pdgfr signaling leads to a reduced vascular basement membrane, which in turn results in enhanced dorsal aorta vessel elasticity and failure to restrict aortic diameter. Our results provide direct in vivo evidence for a functional role for mural cells in patterning and stabilization of the early vasculature through production and maintenance of the vascular basement membrane to prevent abnormal aortic expansion and elasticity.
The Drosophila Hox gene Ultrabithorax acts both in muscles and motoneurons to orchestrate formation of specific neuromuscular connections
Authors: Hessinger Christian , Technau Gerhard M. , Rogulja-Ortmann Ana
Published: December 2016

Hox genes are known to specify motoneuron pools in the developing vertebrate spinal cord and to control motoneuronal targeting in several species. However, the mechanisms controlling axial diversification of muscle innervation patterns are still largely unknown. We present data showing that the Drosophila Hox gene Ultrabithorax (Ubx) acts in the late embryo to establish target specificity of ventrally projecting RP motoneurons. In abdominal segments A2 to A7, RP motoneurons innervate the ventro-lateral muscles VL1-4, with VL1 and VL2 being innervated in a Wnt4-dependent manner. In Ubx mutants, these motoneurons fail to make correct contacts with muscle VL1, a phenotype partially resembling that of the Wnt4 mutant. We show that Ubx regulates expression of Wnt4 in muscle VL2 and that it interacts with the Wnt4 response pathway in the respective motoneurons. Ubx thus orchestrates the interaction between two cell types, muscles and motoneurons, to regulate establishment of the ventro-lateral neuromuscular network.
Translation repression by maternal RNA binding protein zar1 is essential for early oogenesis in zebrafish

Published: December 2016

Large numbers of maternal RNAs are deposited in oocytes and are reserved for later development. Control of maternal RNA translation during oocyte maturation has been extensively investigated and its regulatory mechanisms are well documented. However, translational regulation of maternal RNAs in early oogenesis is largely unexplored. In this study, we generated zebrafish zar1 mutants which result in early oocyte apoptosis and fully penetrant male development. Loss of p53 suppresses the apoptosis in zar1 mutants and restores oocyte development. zar1 immature ovaries show upregulation of proteins implicated in endoplasmic reticulum (ER) stress and the unfolded protein response (UPR). More importantly, loss of Zar1 causes markedly upregulation of zona pellucida (ZP) family proteins, while overexpression of ZP proteins in oocytes causes upregulation of stress related activating transcription factor 3 (atf3), arguing that tightly controlled translation of ZP proteins is essential for ER homeostasis during early oogenesis. Furthermore, Zar1 binds to zona pellucida (zp) mRNAs and represses their translation. Together our results indicate that regulation of translational repression and de-repression are essential for precisely controlling protein expression during early oogenesis.
Calorespirometry reveals that goldfish prioritize aerobic metabolism over metabolic rate depression in all but near-anoxic environments
Authors: Regan Matthew D. , Gill Ivan , Richards Jeffrey G.
Published: December 2016

Metabolic rate depression (MRD) has long been proposed as the key metabolic strategy of hypoxic survival, but surprisingly the effects of changes in hypoxic O2 tensions (PwO2) on MRD are largely unexplored. We simultaneously measured the O2 consumption rate (ṀO2) and metabolic heat of goldfish using calorespirometry to test the hypothesis that MRD is employed at hypoxic PwO2s and initiated just below Pcrit, the PwO2 below which ṀO2 is forced to progressively decline as the fish oxyconforms to decreasing PwO2. Specifically, we used closed-chamber and flow-through calorespirometry together with terminal sampling experiments to examine the effects of PwO2 and time on ṀO2, metabolic heat and anaerobic metabolism (lactate and ethanol production). The closed-chamber and flow-through experiments yielded slightly different results. Under closed-chamber conditions with a continually decreasing PwO2, goldfish showed a Pcrit of 3.0±0.3 kPa and metabolic heat production was only depressed at PwO2 between 0 and 0.67 kPa. Under flow-through conditions with PwO2 held at a variety of oxygen tensions for 1 and 4 h, goldfish also initiated MRD between 0 and 0.67 kPa but maintained ṀO2 to 0.67 kPa, indicating that Pcrit is at or below this PwO2. Anaerobic metabolism was strongly activated at PwO2 ≤1.3 kPa, but only used within the first hour at 1.3 and 0.67 kPa as anaerobic end-products did not accumulate between 1 and 4 h exposure. Taken together, it appears that goldfish reserve MRD for near-anoxia, supporting routine metabolic rate at sub-Pcrit PwO2s with the help of anaerobic glycolysis in the closed-chamber experiments, and aerobically after an initial (<1 h) activation of anaerobic metabolism in the flow-through experiments, even at 0.67 kPa PwO2.
The effect of food quality during growth on spatial memory consolidation in adult pigeons

Published: December 2016

Poor environmental conditions experienced during early development can have negative long-term consequences on fitness. Animals can compensate negative developmental effects through phenotypic plasticity by diverting resources from non-vital to vital traits such as spatial memory to enhance foraging efficiency. We tested in young feral pigeons (Columba livia) how diets of different nutritional value during development affect the capacity to retrieve food hidden in a spatially complex environment, a process we refer to as “spatial memory”. Parents were fed either with high- or low-quality food from egg laying until young fledged, after which all young pigeons received the same high quality diet until the memory performance was tested at 6 months of age. The pigeons were trained to learn a food location out of 18 possible locations in one session, and then their memory of this location was tested 24 hours later. Birds reared with the low-quality diet made fewer errors in the memory test. These results demonstrate that food quality during development has long-lasting effects on memory, with moderate nutritional deficit improving spatial memory performance in a foraging context. It might be that under poor feeding conditions resources are redirected from non-vital to vital traits, or pigeons raised with low-quality food might be better in using environmental cues like the position of the sun to find back where food was hidden.
Hyperspectral photoluminescence imaging of defects in solar cells
Authors: Burud Ingunn , Mehl Torbjørn , Flo Andreas , Lausch Dominik , Olsen Espen
Published: December 2016

The present work is a demonstration of how near infrared (NIR) hyperspectral photoluminescence imaging can be
used to detect defects in silicon wafers and solar cells. Chemometric analysis techniques such as multivariate curve
resolution (MCR) and partial least squares discriminant analysis (PLS-DA) allow various types of defects to be classified
and cascades of radiative defects in the samples to be extracted. It is also demonstrated how utilising a macro lens yields
a spatial resolution of 30 µm on selected regions of the samples, revealing that some types of defect signals originate in
grain boundaries of the silicon crystal, whereas other signals show up as singular spots. Combined with independent
investigation techniques, hyperspectral imaging is a promising tool for determining origins of defects in silicon samples for
photovoltaic applications.

The paper presents the results of cybermetric analysis of Ukrainian protesters` digital footprints in social media (January – February, 2014). Strategies of forming attitudes of protest behavior of Ukrainian citizens in global network are analyzed. Empirical research model included event-analysis, typology reports of events considered using online Internet service monitoring social media and messaging discourse analysis, forming protest attitudes in the Ukrainian users. Structural and meaningful analyses were subjected to digital traces of three periods of development of protest, identified during event analysis. Development of intensity markers allowed to carry out a structural analysis of Internet content, and determining the content of the markers provided semantic content circulating in the global communications network.

Discourse analysis of social media posts established dominance of certain technologies of negative mobilization of protesters: identification of political entities with public threat or sources of discontent; use anthropomorphic metaphors; broadcasting information of provocative character.

In the article the perspectives of further research, involving improvement of methods of analysis of formation protest activity on digital tracks are shown.
Political consensus as a way to ensure continuity of political course in Russia
Authors: Мельников  , Melnikov Nikita
Published: December 2016

The article focuses on the problem of achieving political agreement in the Russian society as a whole, as well as in the political elite. The meaning of the term “political consensus” is considered in the introduction. Then the author writes about dynamics of consensus-building after the break-up of the USSR. The attempts of the values-based consolidation of society and achievement of agreement after V. Putin becoming the President of Russia are described. But based on political science, it is said that object of this consensus is just a current politics, not values and goals of development, and its symbol is a personality of leader. On the base of findings of democratic elitism theorists the author pays attention to the highest political levels as potential subjects of formation of public agreement. After detailed description of features of the Russian political class it is said about possibilities of achieving consensus in Russia, which is necessary for continuity of political course.

Authors: Савчук  , Savchuk Dmitriy
Published: December 2016

The article analyzes the social factors that influence the efficiency of formation of personnel potential of public service. The analysis is based on data from a series of studies conducted among civil servants, as well as in universities among students of specialized training areas and specialties. The main objective was to identify the motives of choice of areas of training or specialty, as well as to learn about formed ideas of the civil service and the degree of its attractiveness as a potential employer. Surveys conducted among civil servants show a high degree of dissatisfaction with the expectations of the data that is the indirect cause of the loss of motivation and incentives for professional and personal development, deterioration of the quality of work, as well as the transition to the commercial structures. A comprehensive approach to address the challenges in the field of formation of personnel potential of public service is necesary, taking into account the effect of both internal and external social factors.

The article shows that multi-level network cooperation can be an effective tool for organizing import substitution industries in the Russian Federation under international sanctions, but its use prevents the lack of scientific and methodological support of its application. It is shown that the existing methodological apparatus designed for single-level outsourcing can not be moved in case of multi-level cooperation because of the fundamental differences between these types of networking. A list of these differences is given. An algorithm for choosing the optimal organizational form, based on the criterion of minimum total costs (which are the sum of investment, management and operating costs) is presented.

Today, at the helm of those issues mostly discussed and create trouble is the improperness of actions to the term of social responsibility. The case besides being accepted as a sub-title of the term of ethics, it can be claimed that the employees have the key role in practice for the point of origin of the ethics discussions. Because, the banks that traditionally provide monetary services, have free movement area in terms of the marketing of some services - despite various regulations. In brief, there exist staffs that use initiative. These initiatives involve different behaviour patterns by the staff to the customers according to their business volumes, giving more importance to more efficient customers and even un-fair practices such as those customers who object are right. However, due to the ethical rules, employees are obliged to procure the execution of activities in accordance with the foundation, objective and policies of the bank and to obey the principles of justice, accuracy, honesty and social responsibility for management. In the study it is mentioned clearly that employees and the management may use initiatives and the discussions on ethics may occur, and then a survey on the level of ethics of the employees working at the banks in Karaman and Konya is conducted. In the survey there are questions directed to demographic distribution and traditional scaled-questions directed to the level of understanding of some ethical issues, besides after presenting some real life cases the attendance of the responders is ensured through asking them to tell how they would behave in such cases. Then a comparison between the reflected (ideal) case and the practice (the reality) is made and some analyses are made on ethical values.

Narrativas fílmicas documentales y dilemas de subjetivación de la experiencia. Estudios de casos argentinos
Authors: Nicola Mariné
Published: December 2016

En este artículo nos abocamos al análisis de la produc-ción fílmica documental cuyas narrativas se centran enla última dictadura cívico–militar argentina (1976–1983)y sus consecuencias a instancias de los juicios orales pordelitos de lesa humanidad que se reactivaron en todoel territorio nacional a partir de la nulidad de las leyesde Obediencia Debida y Punto Final en el año 2003.En este texto trabajamos sobre la representación delos juicios orales por delitos de lesa humanidad desarro-llados en los juzgados federales de la provincia de SantaFe entre 2009 y 2010, instancias donde se colocaronfrente a frente a «víctimas y victimarios». Ello nos llevaa examinar los elementos constitutivos de la imagen yrepensar el tema de la subjetivación de la experienciaque se construye en estos audiovisuales.
Morera y Gardel: «video clip» porteño
Authors: Gagliardi Jorge
Published: December 2016

Eduardo Morera filmó 15 cortometrajes musicales coninterpretación de Carlos Gardel y producción de Fe-derico Valle en 1930, compilados con la denominaciónAsí cantaba Carlos Gardel. Suele clasificarse a estas obrascomo video clip, sin considerar la elaboración posteriorde este género a partir de los años 70, que su circulaciónmasiva comenzó en 1981 por parte de la mtv y que noson producciones de la televisión sino de la cinema-tografía. Por otra parte, a partir de ese ordenamientocircula una disputa por quién es el hacedor pionero deese tipo de texto cuatro décadas antes de la creación delgénero, entre Morera y Gardel, por un lado, y José Bohrpor otro, quien, según lo proferido en su autobiografía,habría hecho una actuación musical en un cortometraje—actualmente desaparecido— con producción de laParamount Pictures. Resulta pertinente, entonces, trataralgunas cuestiones sobre la producción y la recepción de estos cortometrajes, tendientes a incentivar la reflexiónacerca de su clasificación social.

Authors: Triquell Ximena
Published: December 2016

El presente trabajo forma parte de un proyecto mayorcuyo principal objetivo es analizar diferentes repre-sentaciones de la infancia en el cine argentino, con elobjetivo de observar de qué manera tales representa-ciones guardan relación con el momento histórico desu producción.En este trabajo abordamos la representación de niñosen relación con la dictadura a partir de tres ejes: a)como «objetos» de disputa, en una lógica de posesióno carencia, que refiere directamente a la apropiación debebés y niños por parte de los militares; como sucedeen La historia oficial (Puenzo, 1985) o, casi dos décadasdespués, en Cautiva (Biraben, 2005); b) como pequeñosadultos de quienes se espera que afronten la realidad,incluida la militancia de los padres, del mismo modoque lo hacen éstos —Un lugar en el mundo (Aristarain,1992), Kamtchatka (Piñeyro, 2002) y separada también por una década Infancia clandestina (Ávila, 2012)—; yc) como sujetos que miran a los adultos como por ejem-plo en Un muro de silencio (Stantic, 1993) o Amigomío(Meerapfel, 1994).

Authors: Cadús María Eugenia
Published: December 2016

El primer peronismo sostuvo una importante política deintervención estatal en todos los ámbitos de la sociedad,así como una particular política cultural. Observamos lasposibles repercusiones en el campo de la danza escénica,de la política de «democratización del bienestar» plantea-da por este gobierno. En este marco analizamos el filmeMujeres que bailan (1949) dirigido por Manuel Romero,protagonizado por Fanny Navarro y Niní Marshall, ycon participación del Ballet Estable del Teatro Colón.Indagamos en cómo el ballet constituye aquí el lugar deun mundo mágico–romántico pero a la vez peligroso.Esta concepción proporciona un espacio perfecto paradesarrollar una narración con características melodra-máticas que se podría decir que educa mostrando «lonocivo» del mundo del arte. Examinamos el lugar de lamujer trabajadora bailarina de ballet a través de la repre-sentación que se realiza con el lenguaje cinematográfico.

Authors: Andelique Carolina
Published: December 2016

Este trabajo aborda el desarrollo de las proyecciones clan-destinas o alternativas de cine militantes realizadas al in-terior de diferentes organizaciones políticas entre los años1968 y 1973 en la ciudad de Santa Fe. En el contexto decensura y persecución instaurado por la dictadura militarde 1966, la realización de proyecciones de cine militantepor parte de organizaciones políticas se constituye en unacto mismo de militancia para los asistentes, quienes venen éstas una forma más de aportar a la discusión políticay social en la lucha por la liberación.A partir de la pregunta sobre qué vínculo existía entrelos distintos grupos realizadores de cine militante y lasorganizaciones políticas a mediados de los años sesenta, será posible comenzar a pensar cómo las proyeccionesde cine al interior de las organizaciones eran en sí unacto formativo para los militantes, y qué característicasasumía este tipo de proyecciones en los diferentes es-pacios en que se realizaba y a partir de la diversidad depúblico que podía concurrir.Los testimonios de ex militantes que participaroncomo asistentes u organizadores de este tipo de pro-yección clandestina o alternativa serán insumo de estetrabajo, permitiéndonos vislumbrar el valor que comoacto militante tenía dicha participación.
