Modeling of finishing force and torque in ultrasonic-assisted magnetic abrasive finishing process
Authors: Misra Aviral , Pandey Pulak Mohan , Dixit Uday S , Roy Anish , Silberschmidt Vadim V
Published: October 2017

A new finishing technique called ultrasonic-assisted magnetic abrasive finishing integrates ultrasonic vibration with magnetic abrasive finishing process for finishing of workpiece surface more efficiently as compared to magnetic abrasive finishing in the nanometer range. During finishing, two types of forces are generated in ultrasonic-assisted magnetic abrasive finishing, namely, a normal force (indentation force) and a tangential force (cutting force) that produces a torque. The finishing forces have direct control on the rate of change of surface roughness and material removal rate of the workpiece surface. This article deals with the theoretical modeling of the normal force and the finishing torque based on the process physics. In this work, finite element simulations of the electromagnet were performed to calculate a magnetic flux density in the working zone; they were also used to evaluate the normal force on the workpiece surface. The theory of friction for the abrasion of metals was applied together with the effect of ultrasonic vibration to calculate the finishing torque. The developed model predicts the normal force and finishing torque in ultrasonic-assisted magnetic abrasive finishing as functions of the supply voltage, working gap and concentration of abrasive particles in a flexible magnetic abrasive brush. A comparison of theoretical and experimental results is performed to validate the proposed model.
Effect of the rigid constraint body thickness on aluminum alloy powder compact via hot isostatic pressing
Authors: Huang Xina , Lang Lihui , Wang Gang , Duan Wen
Published: October 2017

This work investigated the effects of the rigid constraint body thickness on the mechanical properties and densification of hot isostatic pressing–produced 2A12 aluminum alloy powder compact. With the decrease in the rigid constraint body thickness, the tensile and yield strengths of the powder compact are improved; in addition, the radial and axial displacements increase. These phenomena can be attributed to the decrease in the isostatic pressure shielded by the rigid constraint body. The shielded isostatic pressure is found to be proportional to the rigid constraint body thickness, and therefore, the decrease in the rigid constraint body thickness gives rise to a reduction in the shielded isostatic pressure and enhances the tensile and yield strength properties of the 2A12 powder compact. However, the rigid constraint body thickness has a minor impact on the relative density of powder compact. The fracture morphology of tensile specimens was also studied by scanning electron microscope, and it shows the brittle fracture characteristics.
Is There a Chastity Belt on Perception?
Authors: Witt Jessica K. , Tenhundfeld Nathan L. , Tymoski Michael J.
Published: October 2017

Can one’s ability to perform an action, such as hitting a softball, influence one’s perception? According to the action-specific account, perception of spatial layout is influenced by the perceiver’s abilities to perform an intended action. Alternative accounts posit that purported effects are instead due to nonperceptual processes, such as response bias. Despite much confirmatory research on both sides of the debate, researchers who promote a response-bias account have never used the Pong task, which has yielded one of the most robust action-specific effects. Conversely, researchers who promote a perceptual account have rarely used the opposition’s preferred test for response bias, namely, the postexperiment survey. The current experiments rectified this. We found that even for people naive to the experiment’s hypothesis, the ability to block a moving ball affected the ball’s perceived speed. Moreover, when participants were explicitly told the hypothesis and instructed to resist the influence of their ability to block the ball, their ability still affected their perception of the ball’s speed.
Para-diplomacy: Concept and the Context
Authors: Chatterji Rakhahari , Saha Swagata
Published: October 2017

Globalisation and market reforms have made foreign policymaking a more inclusive and multilayered process. Para-diplomacy and emergence of empowered federating/component units engaging in international interaction call for recalibration of theories and understating of International Relations. The debate over central control versus unit autonomy raised the concern: whether para-diplomacy will turn out to be an asset or a threat for the sovereign state. While state may reap benefits of economic development, para-diplomacy may yet lead to regional imbalance, ethnic mobilisation and separatism. With the focus being shifted to Asia with respect to expanding market and sphere of influence, this article analyses the experience of para-diplomacy between India and China as well as of both with the USA. In doing so, reference is drawn to the past experiences of the West to understand how para-diplomacy took root and how is it practised in different contexts. Considering the economic, political and social implications of para-diplomatic practices in specific contexts, the article concludes with an attempt to find out the institutional space it may tread and the policy options it may hold out especially for India.
The role of divided attention and expertise in melody recognition
Authors: Herff Steffen A. , Czernochowski Daniela
Published: October 2017

When attention is divided during memory encoding, performance tends to suffer. The nature of this performance decrement, however, is domain-dependent and often governed by domain-specific expertise. In this study, 111 participants with differing levels of musical expertise (professional musicians, amateur musicians, and non-musicians) were presented with novel melodies under full- or divided-attention conditions in a continuous melody-recognition task. As hypothesized, melody recognition was modulated by musical expertise, as greater expertise was associated with better performance. Recognition performance increased with every additional presentation of a target melody. The divided-attention condition required concurrently performing a non-music related digit-monitoring task while simultaneously listening to the melodies. Memory performance decreased universally in all groups in the divided-attention condition; however, intriguingly musicians also performed significantly better in the concurrent digit-monitoring task than non-musicians. Results provide insight into the role of expertise, attention, and memory in the musical domain, and are discussed in terms of attentional resource models. In light of resource models, an asymmetrical non-linear trade-off between two simultaneous tasks is proposed to explain the present findings.
Are Type, Frequency, and Daily Time Equally Valid Estimators of Support Needs in Children With Intellectual Disability? A Multitrait–Multimethod Analysis of the Supports Intensity Scale for Children (SIS-C)
Authors: Verdugo Miguel A. , Arias Victor B. , Guillén Verónica M.
Published: October 2017

Support needs represent the intensity of support required by a person with a disability in order to take part in the activities related to normative human functioning. The Supports Intensity Scale for Children (SIS-C) is possibly the most promising tool for assessing and designing individualized support programs in children with intellectual disability. The SIS-C measures support needs across 61 activities, each one assessed along three methods: type of support, frequency, and daily time during which support is to be given. We investigated the impact of method effects in the SIS-C through a bifactor approach to the analysis of multitrait–multimethod matrices. The results suggest that neither intensity nor frequency scales produced method effects that significantly distorted the measurement of support needs. However, the daily support time method had substantial undesirable effects on five of the seven subscales of support needs. Considerations about support needs assessment and future modifications of the scale are discussed.
Domestic Disturbances and Fatal Police Shootings: An Analysis of the Washington Post’s Data
Authors: Pinchevsky Gillian M. , Nix Justin
Published: October 2017

Domestic disturbances are often touted as one of the most dangerous incidents to which police officers respond. Nevertheless, research examining the relative dangerousness of these incidents to responding officers is mixed. Recently, media outlets have compiled rich data on fatal police shootings, which provides the opportunity to examine police responses to domestic disturbances in a different light. Using data compiled by The Washington Post, this study explored whether domestic disturbances that resulted in a fatal shooting were more likely than other fatal shooting incidents to have involved: (a) a civilian armed with a firearm or toy/replica firearm or (b) a civilian who posed an imminent threat to officer or public safety. Findings suggest that there were some, albeit not many, differences in these outcomes between domestic disturbances and seven other incident types. Avenues for future research in this area are provided, along with a discussion about the availability of current data on this topic.
Dynamic analysis of concrete-filled steel tube composite frame against progressive collapse based on benchmark model
Authors: Gao Shan , Xu Man , Zhang Sumei
Published: October 2017

To provide a unified assessment standard in both seismic analysis and progressive collapse analysis, a benchmark model with joint substructure for concrete-filled steel tube composite frame is developed and studied by alternative path method. The effects of failure period on dynamic response of the model and two types of dynamic increased factor are analyzed. Demand–capacity ratio is used to evaluate the progressive collapse behavior of the model. The results show that beyond 0.5 time of natural vibration period, the failure period has almost no effect on the dynamic response of the model. The peak moment–nominal moment capacity ratio of the beams connected to the removed column indicates that the closer the column gets to side column with pin connections, the more potential it has to trigger collapse. The bending stiffness of beam has little effect on the dynamic response of the model when it is greater than the doubled value. Displacement-based dynamic increased factor in linear static analysis is almost identical to load-based dynamic increased factor in linear static analysis in each case of column removal. Compared with the value of load-based dynamic increased factor, the value of displacement-based dynamic increased factor in nonlinear analysis is closer to the recommended value of 2.0 in GSA.
A Red Brick Wall: Anti-Immigrant Rhetoric in a Residence Hall Environment
Authors: Duran Antonio
Published: October 2017

This case study was developed for leadership courses in higher education and student affairs programs, specifically those looking at issues of multiculturalism and social justice. It features a residence hall at a predominantly White institution with a student population and a surrounding town that largely reflect conservative views. Specifically, this case asks educators to think about how they would react to a series of events that indicate xenophobic, racist nativist, and anti-immigrant rhetoric, culminating in a physical barrier being built outside of the hall to symbolize a divide between students. Both the Residence Hall Director and Assistant Residence Hall Director play a key role in responding to these incidents as they hope to strengthen their residence hall community in light of the negative events.
Conducting Analysis in Institutional Ethnography
Authors: Rankin Janet
Published: October 2017

Institutional ethnography (IE) is an innovative approach to research that requires a significant shift in researchers’ ordinary habits of thinking. There is a growing body of methodological resources for IE researchers however advice about how to proceed with analysis remains somewhat scattered and cryptic. The purpose of the first of a two-paper series is to contribute to publications focused exclusively on analysis. The aim is to provide practical tips to support researchers to shift their ordinary habits of thinking. This first paper outlines how this must happen at the outset of the research design. Analysis of the phenomenon under study commences as the research is being formulated. The approaches to analytical thinking outlined in this paper are based on my own IE research and also my experience working with graduate students since 2008. In this first volume of the two-paper set I provide a brief background to the method and direct readers to important IE resources. I outline three core methodological concepts: standpoint, problematic and ruling relations. I discuss how these concepts guide the early analytical thinking that is embedded in the research design and the critical analysis of the literature that is part of the process of analysis in IE. The second paper provides practical advice for working with data.
Factors affecting postoperative pain and delay in discharge from the post-anaesthesia care unit: A descriptive correlational study
Authors: Chan Jason Ju In , Thong Sze Ying , Tan Michelle Geoh Ean
Published: October 2017

Background:

Pain occurring in the post-anaesthesia care unit (PACU) is common, distressing to patients and remains a management challenge for staff. This study aims to identify the factors affecting pain severity and delay in discharge of patients from the PACU.

Methods:

Data from 590 consecutive postoperative patients in the PACU was collected over one month in 2012 at the Singapore General Hospital. Patient demographics, surgical, intraoperative anaesthetic and recovery data were collected. The primary outcome measured was postoperative pain score and secondary outcome was a delay in discharge. Univariate and multivariate logistic regression were performed to determine preoperative and intraoperative variables that may be associated with pain and delayed discharge.

Results:

The majority (67.6%) of patients reported no to mild pain while 32.3% reported moderate to severe pain; 65.4% of patients had delayed discharge and 28.3% of these were a result of uncontrolled pain. Factors associated with moderate to severe postoperative pain included younger age, same day admissions, duration of operation >2 h, abdominal, upper limb and spine surgeries and use of general anaesthesia. Factors associated with delay in discharge included higher body mass index, abdominal, spine and superficial surgeries, use of general anaesthesia, moderate to severe pain score and use of nurse controlled analgesia.

Conclusions:

This study identifies predictive factors for postoperative pain and delay in discharge from the PACU. Knowledge of these factors may help in better clinical judgment for postoperative pain management and can lead to quality improvement measures for patient management and work flow in the PACU.
The Causes and Pervasiveness of DMC: Stakeholder Perceptions of Disproportionate Minority Contact in the Juvenile Justice System
Authors: Dawson-Edwards Cherie , Tewksbury Richard , Nelson Nadia T.
Published: October 2017

This study explores perceptions and awareness of disproportionate minority contact (DMC) by stakeholders in juvenile justice, youth-serving community organizations, schools, social services, and the faith community. This study is derived from a statewide assessment, which included in-person interviews with individuals that have personal and professional relationships within the juvenile justice system. Findings support the contention that individuals are either unaware of the prevalence of DMC, have already formed prejudices about minority youth within the system, or do not appreciate the degree of importance DMC has on the development of minority youth.
Stock Trading and Stock Returns: Understanding the Distributional Properties of the Numbers—The Evidence from India Nifty Fifty
Authors: Jayasree M.
Published: October 2017

Benford’s law which studied the distributional properties of numbers observed that data patterns follow a certain frequency. The application of the Benford law to accounting numbers was tested by Dan Amiram, Zahn Bozanic, and Ethan Roven (2015), and was proven that accounting numbers follow the same frequency. There are several theories that advocated a strong relationship between accounting numbers and stock returns. Taking this as a base, the study aims to investigate whether Benford’s law, which was proven to be working for accounting numbers, would also work for stock trading and stock returns. The study uses data from National Stock exchange of Nifty Fifty stocks. Initially, data of daily stock returns and daily stock trade for five years from 2012 to 2016 are observed for the theoretical distribution. Later, the daily stock returns and daily trading activity for the results announcement months of April and May covering the five years were observed. It was examined whether data of stock returns and trading activity followed the distribution of Prob ( d) = log10 (1+ (1/ d)), for d = 1, 2, 3 ….9. Later the frequency pattern of stock returns and trading activity is tested by KS statistic to conclude whether data followed the same frequency as Benford’s law. The Kernel density estimates were also used to confirm the results.

Published: October 2017

The genus Marinobacterium belongs to the family Alteromonadaceae within the class Gammaproteobacteria and was reported in 1997. Currently the genus Marinobacterium contains 16 species. Marinobacterium rhizophilum CL-YJ9T was isolated from sediment associated with the roots of a plant growing in a tidal flat of Youngjong Island, Korea. The genome of the strain CL-YJ9T was sequenced through the Genomic Encyclopedia of Type Strains, Phase I: KMG project. Here we report the main features of the draft genome of the strain. The 5,364,574 bp long draft genome consists of 58 scaffolds with 4762 protein-coding and 91 RNA genes. Based on the genomic analyses, the strain seems to adapt to osmotic changes by intracellular production as well as extracellular uptake of compatible solutes, such as ectoine and betaine. In addition, the strain has a number of genes to defense against oxygen stresses such as reactive oxygen species and hypoxia.
Consumption Responses to Temporary Tax Incentives: Evidence from State Sales Tax Holidays
Authors: Agarwal Sumit , Marwell Nathan , McGranahan Leslie
Published: October 2017

States offer sales tax holidays (STHs) temporarily exempting items like clothes, shoes, and school supplies from the state sales tax. Spending response to these temporary tax changes are investigated using two datasets: the Diary portion of the Consumer Expenditure Survey and a unique dataset of credit card transactions. Results based on a difference-in-differences methodology show that there are substantial increases in spending on covered goods during these holidays that are not offset by declines in spending before or after the holidays.

Behavioral Responses to Wealth Taxes: Evidence from Sweden
Authors: Seim David
Published: October 2017

This paper provides an empirical assessment of an annual wealth tax. Using Swedish administrative data, I estimate net-of-tax-rate elasticities of taxable wealth in the range [0.09, 0.27]. Cross-checking self-reported assets against asset data unavailable to the tax agency reveals that around a third of the elasticity estimates are due to underreporting of asset values. Difference-in-difference designs further suggest that the responses reflect evasion and avoidance rather than changes in saving. (JEL H24, H26, H31)
Street Prostitution Zones and Crime
Authors: Bisschop Paul , Kastoryano Stephen , van der Klaauw Bas
Published: October 2017

This paper studies the effects of legal street prostitution zones on registered and perceived crime. We exploit a unique setting in the Netherlands where these tippelzones were opened in nine cities under different regulation systems. Our difference-in-difference analysis of 25 Dutch cities between 1994–2011 shows that opening a tippelzone decreases registered sexual abuse and rape by about 30–40 percent in the first two years. For cities which enforced licensing in tippelzones, we also find reductions in drug-related crime and long-term effects on sexual assaults. Effects on perceived drug nuisance depend on the regulation system and the proximity of respondents to the tippelzone. (JEL J16, J47, K42)
Trade Shocks and the Provision of Local Public Goods
Authors: Feler Leo , Senses Mine Z.
Published: October 2017

We analyze the impact of trade-induced income shocks on the size of local government and the provision of public services. Areas in the United States with declining labor demand and incomes due to increasing import competition from China experience relative declines in housing prices and business activity. Since local governments are disproportionately funded through property and sales taxation, declining property values and a decrease in economic activity translate into less revenue, which constrains the ability of local governments to provide public services. State and federal governments have limited ability to smooth local shocks, and the impact on the provision of public services is compounded when local income shocks are highly correlated with shocks in the rest of the state. The outcome is a relative decline not only in incomes but also in the quality of public services and amenities in trade exposed localities. (JEL F14, F16, H41, H71, R12, R31, R51)
Does Neurologic Level in Pediatric Patients with Myelodysplasia Affect Body Fat?
Authors: Maguire Kathleen J. , Gurbani Barkha N. , Caron Marie-Josee , Zemanovic Jason R. , Howat Linda , Otsuka Norman Y.
Published: October 2017

Background: Historically, pediatric patients with myelodysplasia have been found to have a higher percentage of body fat than age-matched, healthy controls. This study examines the relationship between body fat percentage and age, sex, neurologic level, walking ability, and comorbidities in pediatric myelodysplasia patients.

Methods: A total of 91 patients underwent a thorough history and physical to document body fat percentage, neurologic level, and walking ability; a chart-review determined comorbidities.

Results: Females with myelodysplasia had significantly higher percent body fat than males (p = 0.02). Among females, body fat percentage increased with age (1.2% per year). Males who were community ambulators had lower body fat than those who were household ambulators or nonambulatory. In both sexes, those with mid/high neurologic levels had significantly higher body fat than those with low neurologic levels. There was no relationship between comorbidities and body fat.

Conclusions: In patients with higher neurologic levels and impaired walking abilities, treatment aimed at controlling obesity should be integral to the care of myelodysplasia patients.
Vulvodynia and depression – a case study
Authors: Gerhant Aneta , Dziwota Ewelina , Perzyńska-Starkiewicz Aneta , Derewianka-Polak Magdalena , Olajossy Marcin
Published: October 2017

Cel pracy
Celem pracy jest analiza przypadku wulowdynii współwystępującej z depresją.

Metoda
Analiza dokumentacji medycznej oraz przypadku klinicznego.

Wyniki
45-letnia kobieta została przyjęta do kliniki z powodu dokuczliwego bólu sromu
z towarzyszącymi objawami zespołu depresyjnego, nieustępującego po duloksetynie
w maksymalnej tolerowanej dawce 60 mg/d. Pacjentka od 11 lat cierpi na nawracające bóle
w zakresie sromu lub okolicy skroni i żuchwy z towarzyszącą depresją. W przeszłości dwukrotnie podjęła próbę samobójczą. Pierwotnie rozpoznawano u niej wulowodynię, następnie kilkukrotnie hospitalizowana psychiatrycznie z rozpoznaniami klinicznymi ze spektrum zaburzeń nastroju. Ból i objawy zespołu depresyjnego ustępowały po lekach przeciwdepresyjnych: klomipraminie, escitalopramie, wenlafaksynie. Analiza historii choroby, przeprowadzone badanie ginekologiczne potwierdziło występowanie u pacjentki wulwodynii. Remisję w zakresie bólu i objawów afektywnych osiągnięto jednoczasowo po włączeniu do leczenia gabapentyny w dawce 900 mg/d. Ostatecznie u pacjentki rozpoznano wulwodynię i zaburzenia depresyjne nawracające. Postawienie takiej diagnozy byłoby jednak w pełni uprawnione, gdyby w przyszłości wystąpił u niej epizod depresyjny niezwiązany z bólem.

Wnioski
1. Wulwodynia często współwystępuje z zaburzeniami depresyjnymi.
2. Zaburzenia depresyjne mogą stanowić czynnik ryzyka zachorowania na wulowodynię, jak również pojawiać się wtórnie do dolegliwości bólowych.
3. Rozpowszechnienie innych funkcjonalnych syndromów bólowych takich jak fibromialgia, zespół skroniowo-żuchowowy u pacjentek z wulwodynią jest większe niż w ogólnej populacji kobiet.
4. Ryzyko samobójstwa w wulwodynii, podobnie jak
w innych przewlekłych syndromach bólowych jest relatywnie wysokie, szczególnie w sytuacji współwystępowania objawów depresyjnych.
Ninguém ouve quando todos falam: sobre o futuro dos meios de comunicação social na vida mediática
Authors: Deuze Mark
Published: October 2017

O futuro da comunicação social enquanto indústria e em termos dos profissionais a que dá emprego é analisado utilizando a teoria da comunicação social e a perspetiva da produção relativamente à comunicação social enquanto trabalho. Dada a dependência da sociedade nos meios de comunicação para contar as suas histórias, e o facto de as vidas quotidianas das pessoas serem representadas nesses mesmos meios de comunicação, o momento em que estes mundos colidem constitui um ponto de partida excelente para uma exploração futurística. Utilizando uma taxonomia dos meios de comunicação social como artefactos, atividades e organizações sociais, o trabalho mediático é analisado do ponto de vista de uma oportunidade estética, de uma chamada ética à ação e de uma responsabilidade social.
The perceptions of the care and support services available for nurses caring for patients with hiv/aids in the intermediate hospital oshakati

Published: October 2017

Purpose: The rationale of thisresearch was to describe the care and support services given to nurses who are responsible for providing care for patients with both the human immunedeficiency virus. Accordingly, the study investigated HIV/AIDS care support preferences for nurses.Method: The study used a descriptive research design. The respondents comprise twenty-four (24) nurses who were conveniently selected from Intermediate Hospital of Oshakati (IHO).The The requisite data was collected via questionnaires, which were distributed to the respondents. The respondents were required to fill in the questionnaires and furnish their views on their perceptions regarding the care and support services available for nurses caring for patients with HIV/AIDS in the Intermediate Hospital Oshakati.Findings: The study revealed a lack of guidance for nurses who provide care for immunocompromised patients. The study also found that the majority of challenge's nurses face in providing care, and support involved emotional pain and under staff.Conclusions: The study concluded that the nurses themselves were both affected and infected by HIV/AIDSbut that these same nurses are expected to provide treatment to patients with HIV/AIDS. Support systems for nurses constitute an extremely important workplace issue, although the nurses conceded that the hospital in question did not have sufficient capacity to provide such support systems.Recommendations: This study suggested that the hospital leadership could function as a team in developing supportive interventions that match the problems/needs identified. Nurses should also takes to take an active role in caring for themselves.

Partiendo de un recorrido histórico del auge del concepto de vulnerabilidad, luego se expone la confusa situación actual del uso de la categoría de embarazo vulnerable. Finalmente, se reconoce la relevancia de la noción de vulnerabilidad al comprender la práctica clínica desde la antropología médica y se insta a una investigación interdisciplinar más rigurosa en torno a ella.
Derecho a la protección de la salud y vulnerabilidad
Authors: Loureiro João Carlos
Published: October 2017

En este artículo se intenta, en primer lugar, clarificar el concepto de vulnerabilidad, considerando también la fragilidad estructural y epocal. Para una comprensión del derecho a la protección de la salud, se empieza por una reflexión en el plano de los bienes fundamentales y se analiza después ese derecho en las constituciones portuguesa y española. Además, tratamos la asociación entre vulnerabilidad y derecho, desde un nivel fundamental –en diálogo con Herbert Hart– hasta otras relaciones entre estos dos términos en el campo de la salud. Por último, consideramos los intentos posthumanistas de decir adiós a la fragilidad humana.
Effects of Practical Blood Flow Restriction Training on Adolescent Lower-Body Strength

Published: October 2017

Luebbers, PE, Witte, EV, and Oshel, JQ. Effects of practical blood flow restriction training on adolescent lower-body strength. J Strength Cond Res 33(10): 2674–2683, 2019—The purpose of this study was to examine the effects of a practical blood flow restriction (BFR) training program on lower-body strength of high school weightlifters. Twenty-five students were divided into 3 groups. For 6 weeks, each group completed the same resistance training program with the exception of the parallel back squat exercise (2 d·wk−1), which was different for each group. One group (HI) completed a traditional high-load (≥65% 1 repetition maximum [1RM]) back squat protocol with 3 sets of low repetitions (≤10). The LO group completed the squat exercise using a relatively light load (≤30% 1RM) for 1 set of 30 repetitions and 3 sets of 15 with 30 seconds of rest between sets. The LO + BFR group followed the same protocol as LO, but did so with blood flow restricted. One repetition maximum back squat tests were conducted before the start of the program and again on conclusion, the values of which were used as the dependent measure. A 3 × 2 (group × time) repeated-measures analysis of variance revealed a significant interaction (p = 0.043). Follow-up tests were conducted to explore the interaction. Paired-sample t-tests for each group indicated a significant increase in leg strength for the LO + BFR group (p = 0.005) but not for the HI (p = 0.142) or LO groups (p = 1.00). This suggests that a practical BFR training program may be effective in increasing 1RM squat performance of high school students.
Observar la violencia 2.0: comportamiento cómplice, de la adolescencia gallega, en función del género.
Authors: Méndez-Lois Mª José , Villar Varela Milena , Barreiro Fernández Felicidad
Published: October 2017

En la actual situación de revolución tecnológica, el ciberespacio se convierte en el nuevo ámbito de relaciones, un lugar cotidiano para los y las jóvenes de nuestro mundo. Esto incrementa el riesgo de violencia al desaparecer las barreras espaciales que delimitaban la comunicación entre iguales, y da lugar al nacimiento de un nuevo concepto: la violencia 2.0.Este trabajo analiza las experiencias de observación de conductas violentas 2.0, de la población adolescente, en entornos virtuales e identifica factores asociados con el comportamiento ciberobservador en este colectivo. En el estudio participaron 615 estudiantes de tercero y cuarto de la ESO escolarizados en Galicia y seleccionados mediante muestreo por conveniencia.En relación a las experiencias, los resultados indican que los y las jóvenes consultados han observado múltiples conductas violentas y se han encontrado diferencias por sexo en lo que unas y otros han observado.Los factores asociados a las conductas violentas observadas que se han identificado son tres que guardan relación con las conductas verbales agresivas mostradas ante lo que difiere del canon normativo heteropatriarcal, la violencia sexual y, por último, las experiencias asociadas al mito del amor romántico.

Saccharomyces cerevisiae contains two genes for each core histone, which are presented as pairs under the control of a divergent promoter, i.e., HHT1-HHF1, HHT2-HHF2, HTA1-HTB1 and HTA2-HTB2. HHT1-HHF1, and HHT2-HHF2 encode histone H3 and H4 with identical amino acid sequences but under the control of differently regulated promoters. Previous mutagenesis studies were carried out by deleting one pair and mutating the other one. Here, we present the design and construction of three additional libraries covering HTA1-HTB1, HTA2-HTB2, and HHT1-HHF1 respectively. Together with the previously described library of HHT2-HHF2 mutants, a systematic and complete collection of mutants for each of the eight core S. cerevisiae histone genes becomes available. Each designed mutant was incorporated into the genome, generating three more corresponding libraries of yeast strains. We demonstrated that, although, under normal growth conditions, strains with single-copy integrated histone genes lacked phenotypes, in some growth conditions, growth deficiencies were observed. Specifically, we showed that addition of a second copy of the mutant histone gene could rescue the lethality in some previously known mutants that cannot survive with a single copy. This resource enables systematic studies of function of each nucleosome residue in plasmid, single-copy, and double-copy integrated formats.
JAV LIETUVIŲ ŠVIETIMO, SAVIŠVIETOS IR SKAITYMO KLAUSIMAI IŠEIVIJOS PERIO DIKOJE (IKI 1904 M.)
Authors: Misiūnas Remigijus
Published: October 2017

Švietimas ir savišvieta yra vienos esminių knygų leidybos plėtros sąlygų. Švietimo, savišvietos, skaitymo temos buvo aktualios įvairiuose JAV lietuvių išeivijos laikraščiuose. Peržiūrėjus beveik 20 įvairios apimties išeivių periodikos leidinių komplektų, galima teigti, kad XIX a. pabaigoje JAV pradėjo formuotis vaikų ir suaugusiųjų švietimo struktūros, atsirado institucijos, rėmusios aukštojo išsilavinimo siekį. Visa tai tiesiogiai ar netiesiogiai siejosi su leidyba. Kartu pradėjo klostytis ir savišvietos tradicijos, nuolat augo spaudos, kaip pagrindinio jos šaltinio, reikšmė, didėjo skaityti išmokusių išeivių skaičius. Taip gausėjo spaudos skaitytojų bei pirkėjų, formavosi leidybos santykis su švietimo įstaigomis. Straipsnyje analizuojami šie ir kiti su tuo susiję klausimai (tuo metu besiformavusių išeivijos politinių dešiniosios ir kairiosios srovių požiūriai į švietimą ir savišvietą, ypač skaitymą). Nagrinėjama, kaip šios politinės srovės išnaudojo švietimą ir savišvietą savo ideologijos plėtrai pasitelkdamos leidybą ir taip plėsdamos jos repertuarą bei kiekybinius rodiklius.
SOVIETINĖS CENZŪROS ISTORIOGRAFIJA: PAGRINDINĖS TYRIMŲ KRYPTYS IR CENZŪROS SAMPRATOS
Authors: Sėdaitytė Edita
Published: October 2017

Sovietinė cenzūra nėra tik viešojo sektoriaus (spaudos ir masinio informavimo priemonių) kontrolė, tai kompleksinis reiškinys, apimantis daugybę sričių – nuo viešosios iki privačiosios erdvės, nuo institucinės, reglamentuotos kontrolės iki vidinės savicenzūros. Tad cenzūros tyrimai aktualūs įvairių mokslo sričių atstovams. Straipsnio tikslas – išnagrinėti sovietinės cenzūros sampratas ir tyrimų kryptis istoriografijoje. Rengiant straipsnį buvo analizuoti moksliniai darbai, kuriuose įvairiais aspektais paliečiami sovietinės cenzūros klausimai. Pastebėta, kad cenzūros klausimai nagrinėjami ir bendrame sovietinės okupacijos istorijos kontekste, ir tik sovietmečio kultūrinį gyvenimą, KGB veikimo priemones, menininkų kūrėjų santykį su sistema, spaudos ir leidybos istoriją bei atminties institucijų veiklą analizuojančiuose darbuose. Vien tik cenzūrai skirtuose tyrimuose daugiausia susitelkiama į cenzūrą vykdžiusių institucijų veiklos analizę. Cenzūros raiška atminties institucijose nagrinėjama analizuojant bibliotekų fondų valymo, knygų naikinimo (bibliocido), specialiųjų fondų kūrimo klausimus. Lietuvos istorikai sovietinės cenzūros reiškinį pateikia kaip režimo primestą, vienapusę totalitarinę kontrolę. Užsienio autoriai dažniau remiasi Pierre’o Bourdieu ir Michelio Foucault teorijomis, į cenzūrą žvelgia ir kaip į kontrolę, ir kaip į pozityvią kultūrą bei vientisą viešąją komunikaciją formuojančią galią. Cenzūros samprata ir apibrėžimas tyrimuose varijuoja nuo institucinio, valstybės vykdomo spaudos suvaržymo iki cenzūros kaip „ribų“ ar „informacinio barjero“ suvokimo. Cenzūra gali būti nagrinėjama ir kaip veikianti institucija, ir kaip tos institucijos veikimo priemonės, ir kaip masinės komunikacijos ypatybė.
LIETUVOS LITERATŪRINĖS PREMIJOS IR JŲ REIKŠMĖ LEIDYBAI
Authors: Lebednikaitė Lina
Published: October 2017

Straipsnis skiriamas dabartinei Lietuvos literatūrinių premijų situacijai įvertinti: nagrinėjama, kiek ir kokių premijų yra šiuo metu Lietuvoje ir kaip literatūrines premijas vertina Lietuvos leidėjai, kaip šios premijos panaudojamos leidybai. Atsiribojama nuo vaikų literatūros apdovanojimų, premijų grožinės literatūros vertėjams, įvairiems kitiems meno kūrėjams, knygos meno apdovanojimų, įvairių literatūros konkursų. Tyrimas atliktas remiantis interviu su Lietuvos leidyklų atstovais medžiaga bei jos interpretacija, pasitelkus Claire Squires premijų funkcijų modelį. Prieita prie išvados, kad Lietuvos literatūrinių premijų gausa (36) žinoma ne visiems leidėjams, ypač tai pasakytina apie miestų ir rajonų savivaldybių premijas, bet leidyklos patvirtina, jog tokios premijos – reikšmingas rajonų kultūrinio gyvenimo ir literatūrinio poreikio skatinimas. Lietuvoje reiškiasi tik pirmasis literatūrinių premijų vaidmuo: kūrėjų darbai yra pastebimi ir vertinami, tačiau leidyboje nepasinaudojama kitomis premijų teikiamomis galimybėmis. Pasaulio premijų kontekste ryški knygų diskusijų kultūra Lietuvoje yra didžiausia menko premijų žinomumo ir panaudojimo spraga – tokios kultūros mes neturime. Trūksta kanalų knygoms aptarti, premijos negeba pritraukti žiniasklaidos dėmesio arba jis būna itin mažas, stokojama premijų organizatorių ir leidyklų bendradarbiavimo. Lietuvos leidyklos stengiasi kreipti dėmesį į literatūrines premijas, tačiau tai daro per menkai, nesistemingai, tik pavieniais atvejais, nedrįsta eksperimentuoti ir rizikuoti. Premijos, turinčios sukurti masinį skaitančios visuomenės susidomėjimą literatūra, Lietuvoje tinkamai nepanaudojamos.
