Resistance to change, work engagement and psychological capital of academics in an open distance learning work environment
Authors: Diedericks Johanna C. , Cilliers Frans , Bezuidenhout Adéle
Published: November 2019

Orientation: In the present knowledge economy, the external environment is rapidly evolving and organisations are increasingly demanding much more from their employees. Psychological capital (PsyCap) and work engagement (WE), seen as positive human resource strengths and psychological capacities, can be developed and effectively managed for enhanced work performance. Employees’ resistance to change (RTC) is a key barrier to organisational change.Research purpose: To investigate the interrelationships between PsyCap, WE and RTC of open distance learning (ODL) academics.Motivation for the study: Little empirical research has investigated the application of positive work and organisational psychological functioning of ODL academics. Universities can use the study results to develop strategies which may enable institutions and individuals to flourish through positive well-being despite change.Research approach/design and method: A quantitative survey including a probability sample of 208 (N = 208) academics was utilised. Structural equation modelling was used to analyse the data.Main findings: The results reveal a meaningful positive relationship between the positive psychological constructs of PsyCap and WE, and a meaningful negative relationship between the psychodynamic construct RTC, and the positive psychological constructs of PsyCap and WE. Structural equation modelling indicated an adequate fit of conceptual structural model.Practical/managerial implications: Results suggest that reduced RTC and increased positive psychological behaviour could contribute to a positive organisation and individual well-being in a changing work environment.Contribution/value-add: This study adds to the body of knowledge and insights into positive work and organisational functioning of academics in a changing ODL work environment.

The role of Cardiac Magnetic Resonance (CMR) in the diagnosis of cardiomyopathy: A systematic review
Authors: Zhaohui Wang
Published: November 2019

BackgroundMyocardial pathologies are significant causes of morbidity and mortality in patients worldwide. Ischemic and non-ischemic cardiomyopathies have become a worldwide epidemic of the 21st century with an increasing impact on health care systems. The 2012 European Society of Cardiology and 2013 American College of Cardiology Foundation/American Heart Association guidelines provide current therapy guidance to reduce mortality and morbidity.MethodsThis was a systematic review involving cardiac magnetic resonance (CMR) studies for the diagnosis of cardiomyopathy from January 2013 to April 2017. Out of 62 reviewed studies, only 12 were included in our study.ResultsThe average sensitivity and specificity of CMR in the diagnosis of cardiomyopathy was 86.75% (95% confidence interval [CI], 70.30% to 92.58%) and 81.75% (95% CI, 73.0% to 87.6%), respectively, and the positive predictive and negative predictive values were 80.17% and 86.75%, respectively.ConclusionDespite some limitations, our study shows that CMR has high sensitivity, specificity, and positive predictive value in diagnosing different types of cardiomyopathy. CMR may be used to differentiate types of cardiomyopathy, accurately quantify the chamber dimensions, volumes, and cardiac function, which make it useful for prognosis as well.
Common impairments and functional limitations of HIV sequelae that require physiotherapy rehabilitation in the medical wards at Queen Elizabeth Central Hospital, Malawi: A cross sectional study
Authors: Banda Gift Treighcy
Published: November 2019

IntroductionThe progression of human immunodeficiency virus (HIV) to acquired immune deficiency syndrome (AIDS) and the use of anti-retroviral therapy (ART) have resulted in a range of complications, which affect different body systems and result in functional limitations and disabling impairments. ObjectiveTo investigate HIV-related impairments and functional limitations that require physiotherapy rehabilitation in patients admitted to the medical wards at Queen Elizabeth Central Hospital in Blantyre, Malawi. MethodsThis was a descriptive quantitative cross-sectional study involving the participation of 32 female (59.3%) and 22 male (40.7%) adults living with HIV and admitted to the medical wards at Queen Elizabeth Central Hospital. We collected data using a questionnaire that consisted of the World Health Organization Disability Assessment Schedule 2 (WHODAS2.0) and some demographic questions. Results were analysed using the Statistical Package for the Social Sciences (SPSS). ResultsParticipation in society was the most frequently reported functional complication; the least common limitation was getting along with people (70.3%, n = 38 participants) and interaction with others (24%; n=13). Shortness of breath (55%; n=30), muscle weakness (44.4%; n=24) and joint and muscle pain (37%; n=20) were the most commonly reported impairments. Participation restriction in the society affected both males (77.3%) and females (70.7%). The least common limitation that required physiotherapy for both males and females was getting along with people (26.6% and 25%, respectively). On average, male and female participants had a disability severity score of 48.5±4.6 and 42.2±22.8, respectively. ConclusionOur data showed that there is a clear need for early intervention to halt or delay the progression of complications to avoid severe disability; this is not only good for the patient but also for the socioeconomic state of the nation. Timely and full functional assessment, as well as referral of people living with HIV/AIDS for rehabilitation, is an important step forwards.
The relationship between measures of obesity and atherogenic lipids among Nigerians with hypertension
Authors: Michael Olamoyegun A
Published: November 2019

AimThis study aimed to determine the relationship between measures of obesity and serum lipid levels among hypertensive patients.MethodsThis was a cross-sectional study in which participants newly diagnosed with hypertension formed the study population. A range of demographic and anthropometric data was obtained, including weight, height, and waist and hip circumference. Fasting serum lipids were also measured, including total cholesterol, high density lipoprotein cholesterol (HDL-C) and triglycerides (TG). Low density lipoprotein cholesterol (LDL-C) was calculated using Friedewald formula. Statistical analysis was then carried out to determine the relationship between anthropometric indices and lipid profile levels. ResultsThe study population consisted of 124 male and 290 female subjects with a mean age of 66±16.95 years (range, 30–100 years).The female subjects were older than the male subjects (p=0.020). Our analysis showed that 85%, 58.5% and 30.7% of the study population had abnormal waist circumference (WC), abnormal waist-hip ratio (WHR) and a body mass index (BMI) >25 kg/m2, respectively. Decreased HDL-C (70.1%) was the commonest lipid abnormality detected, followed by elevated LDL (6.0%). None of the anthropometric indices were independent predictors of abnormal lipid levels. However, advanced age and female sex were independent predictors for at least one serum lipid abnormality.ConclusionNone of the measures of obesity could independently predict abnormal lipid levels in individuals newly diagnosed with hypertension. However, female sex, advanced age and systolic blood pressure were independently associated with abnormal serum lipids. Encouraging regular exercise, and the possible addition of statins, may be beneficial in addressing both obesity and dyslipidaemia.
The knowledge versus self-rated confidence of facility birth attendants with respect to maternal and newborn health skills: the experience of Nigerian primary healthcare facilities
Authors: Esan Oluwaseun
Published: November 2019

BackgroundCompetent and skilled birth attendants are critical in the reduction of maternal and infant morbidity and mortality at delivery. This study aimed to determine the association between knowledge and self-rated confidence in facility birth attendants affiliated with maternal and neonatal health (MNH) interventions.MethodsA descriptive cross-sectional study was conducted in 24 primary healthcare facilities in Osun state, Nigeria among 128 consenting facility birth attendants who were selected via a multi-stage sampling technique. Each attendant received a semi-structured interviewer-administered questionnaire. The dependent variables included the respondent’s level of knowledge in MNH interventions and their self-rated confidence in MNH skills such as the provision of antenatal care service, normal labour, use of a partograph and the management of obstetric complications and post-partum haemorrhage. Bivariate analysis of factors associated with knowledge and self-rated confidence in MNH skills was performed with statistical significance set at p<0.05.ResultsOnly 48 (37.5%) of the respondents had good knowledge of all of the assessed interventions; worse performances were reported with regards to the respondent’s knowledge of normal labour and partograph use. However, 96 (75%) of respondents were confident in performing 75% of the skills assessed. Our analysis identified two factors that were significantly associated with a good knowledge of MNH skills: the cadre of the birth attendants (p<0.001) and training in life-saving skills (p=0.001). The knowledge of our respondents relating to most of the MNH interventions assessed was not significantly associated with their self-rated confidence in the required skills.ConclusionThe confidence of facility birth attendants in MNH skills was not knowledge-based and could frustrate national efforts to reduce maternal and perinatal deaths. We recommend effective and evidence-based training of all cadres of facility birth attendants to ensure that the skills being practiced clinically are based on adequate knowledge.
Reservoir-scale transdimensional fracture network inversion
Authors: Somogyvári Márk , Kühn Michael , Reich Sebastian
Published: November 2019

Abstract. The Waiwera aquifer hosts a structurally complex
geothermal groundwater system, where a localized thermal anomaly feeds the
thermal reservoir. The temperature anomaly is formed by the mixing of waters
from three different sources: fresh cold groundwater, cold seawater and warm
geothermal water. The stratified reservoir rock has been tilted, folded,
faulted, and fractured by tectonic movement, providing the pathways for the
groundwater. Characterization of such systems is challenging, due to the
resulting complex hydraulic and thermal conditions which cannot be
represented by a continuous porous matrix. By using discrete fracture network models (DFNs) the discrete aquifer
features can be modelled, and the main geological structures can be
identified. A major limitation of this modelling approach is that the
results are strongly dependent on the parametrization of the chosen initial
solution. Classic inversion techniques require to define the number of
fractures before any interpretation is done. In this research we apply the transdimensional DFN inversion methodology
that overcome this limitation by keeping fracture numbers flexible and gives
a good estimation on fracture locations. This stochastic inversion method
uses the reversible-jump Markov chain Monte Carlo algorithm and was
originally developed for tomographic experiments. In contrast to such
applications, this study is limited to the use of steady-state borehole
temperature profiles – with significantly less data. This is mitigated by
using a strongly simplified DFN model of the reservoir, constructed
according to available geological information. We present a synthetic example to prove the viability of the concept, then
use the algorithm on field observations for the first time. The fit of the
reconstructed temperature fields cannot compete yet with complex
three-dimensional continuum models, but indicate areas of the aquifer where
fracturing plays a big role. This could not be resolved before with
continuum modelling. It is for the first time that the transdimensional DFN
inversion was used on field data and on borehole temperature logs as input.
Application of time-of-flight aerosol mass spectrometry for the real-time measurement of particle phase organic peroxides: An online redox derivatization – aerosol mass spectrometer (ORD-AMS)
Authors: Weloe Marcel , Hoffmann Thorsten
Published: November 2019

Abstract. Aerosol mass spectrometers (AMS) are frequently applied in atmospheric aerosol research in connection with climate, environmental or health related projects. This is also true for the measurement of the organic fraction of particulate matter, still the least understood group of components contributing to atmospheric aerosols. While quantification of the organic/inorganic aerosol fractions is feasible, more detailed information about individual organic compounds or compound classes can usually not be provided by AMS measurements. In this study we present a new method to detected organic peroxides in the particle phase in real-time using an AMS. Peroxides (ROOR') are of high interest to the atmospheric aerosol community due to their potentially high mass contribution to SOA, their important role in new particle formation and their function as ‘reactive oxygen species’ in aerosol-health-related topics. To do so, supersaturated gaseous triphenylphosphine (TPP) was continuously mixed with the aerosol flow of interest in a condensation/reaction volume in front of the AMS inlet. The formed triphenylphosphine oxide (TPPO) from the peroxide/TPP reaction was then detected by an aerosol mass spectrometer (AMS), enabling the quantitative determination of peroxide with a time resolution of one to two minutes. The method was tested with freshly formed and aged biogenic VOC/ozone SOA as well as in a short proof-of-principle study with ambient aerosol.
Seasonal and Diurnal Dynamics of Subglacial Channels: Observations Beneath an Alpine Glacier

Published: November 2019

Abstract. Water flowing below glaciers exerts a major control on glacier basal sliding speeds. However, our knowledge on the physics of subglacial hydrology and its link with sliding is limited by lacking observations. Here we use a two-year long dataset made of on-ice measured seismic and in-situ measured glacier basal sliding speed records on the Glacier d’Argentière (French Alps) to investigate the physics of subglacial channels and its potential link with glacier basal sliding. Using dedicated theory and concomitant measurements of water discharge, we quantify temporal changes in channels hydraulic radius and hydraulic pressure gradient. At seasonal timescales we observe, for the first time, that hydraulic radius and hydraulic pressure gradient present a four-fold increase from spring to summer, followed by a comparable decrease towards autumn. At low discharge during the early and late melt season channels respond to changes in discharge mainly through changes in hydraulic radius, a regime that is consistent with predictions of channels behaving at equilibrium. In contrast, at high discharge and high short-term water-supply variability (summertime), channels undergo strong changes in hydraulic pressure gradient, a behavior that is consistent with channels being out-of-equilibrium. This out-of-equilibrium regime is further supported by observations at the diurnal scale, which demonstrate that channels pressurize in the morning and depressurize in the afternoon. During summer we also observe high and sustained basal sliding speeds, supporting that the widespread inefficient drainage system (cavities) is likely pressurized concomitantly with the channel-system. We propose that pressurized channels help sustain high pressure in cavities (and therefore high glacier sliding speeds) through an efficient hydraulic connection between the two systems. Using the two regimes herein observed in channels seasonal-dynamics as constraints for subglacial hydrology/ice dynamics models may allow to strengthen our knowledge on the physics of subglacial processes.

High Turnover (TO) rate among Fast Food Industry (FFI) employees is a critical issue faced by the Jordanian hospitality industry and be detrimental to the growth of the industry. Following that, is important to analyse the factors that lead to high TO rate among FFI employees. This study aims to examine the effect of Human Resource Management Practices (HRMP) and Intention to Leave (ITL) among FFI employees in Jordan. Five HRMP have been included in this study namely training, reward, benefit, performance appraisal and staffing. Using a sample of 245 FFI front-line employees working in Amman, this study has employed a quantitative research approach to answer the research questions. Multiple regression analyses using SPSS was performed to test the hypotheses of this study. As expected, HRMP namely, reward and benefit dimensions of HRMP found to be most significant practices in influencing ITL in this study. The findings of this study contribute to existing literature on the management of Human Resource (HR) and employee TO. It provides insights on the relationships between HRMP and ITL. Practical implications are also provided to managers to reduce TO among FFI employees in Jordan.

Published: November 2019

The soybean crop is extremely important for Brazilian agribusiness, generating millions of dollars in the country’s exports. Since its introduction in Brazil, soybean has undergone a process of technological modernization, receiving in the recent year’s new technologies that have provided a revolution in the production system, increasing mainly grain yield, as well as facilitated phytosanitary managements (pests, diseases, and weeds) and edaphoclimatic adaptation. Brazilian soybean producers yearn for new genotypes that make it easier to manage the crop and reduce input expenditures. New technologies are emerging or being improved to meet this demand. This review explores the technologies that are already available to soybean producers, inserted by the molecular breeding, such as Inox, Intacta, Cultivance, Libert Link and Enlist E3. It also brings the news that will be available to the market in a few years, such as Intacta 2 Xtend, Hb4, and other technologies to increase phenotyping and genotyping in breeding programs and insertion of characteristics to increase plant efficiency. Biotechnology is advancing at a frenetic pace and year after year, new techniques and tools are being made available for breeding programs around the world, which result in the production of new productive cultivars, conventional or transgenic, that are resistant to abiotic and biotic factors.
The Plight of Women Against Housing Challenges in the Eastern Cape Province of South Africa
Authors: Admin Henry Jacob Festus Ssekibuule D.
Published: November 2019

This paper touches day to day social and economic issues affecting women bearing in mind the historical difficulties of women in South Africa during the apartheid years to participate in the main stream of the economy was without iota of doubt incomprehensible and thought-provoking precisely because women were not permitted to have their own houses. The paper unapologetically provides an empirical narrative account of the plight of women in housing. The paper argues that the notion of housing in South Africa is still one of the greatest challenges in the post 1994 dispensation due to an extremely complicated and disintegrated bureaucratic system that was inherited from defunct non-operational apartheid government. Issues of homelessness, unemployment, poverty and inequality are crucial to understand why women rights were violated and accounts for the reason for transformative shift to restorative justice in the post-apartheid democracy. Over 22 years of democracy, human rights violation and excessive problems of homelessness are still a sorry state of affair despite progressive improvement in human settlement. The qualitative study relies not only on historical facts but also triangulated empirical evidence of what was observed and engaged with key informants interviewed to made compelling conclusions and propositions about the plight of women in South Africa, especially in the Eastern Cape Province.
Estimating child linguistic experience from historical corpora
Authors: Kodner Jordan
Published: November 2019

Child language acquisition is often identified as one of the primary drivers of language change, but the lack of historical child data presents a challenge for empirically investigating its effect. In this work, I observe the relationship between lexicons extracted from modern child-directed speech and those drawn from modern and historical literary corpora in order to better understand when language acquisition can be modeled over historical and non-child corpora as it is over child corpora. The type frequencies of morphophonological and syntactic-semantic patterns occur at similar type frequencies in these corpora among high token frequency items, and furthermore, when a learning algorithm is applied to lexicons sampled from these sources, it consistently achieves the same learning outcomes in each. With appropriate care and pre-processing, modern and historical text corpora are effectively interchangeable with child-directed speech corpora for the purpose of estimating child lexical experience, opening a path for modeling language acquisition where child-directed corpora are not available.
Analysis of Economy and Trade among China, India, and Russia under the Belt and Road Initiative
Authors: Chen Jui-Lung , Jung Hsiung-Shen
Published: November 2019

The Belt and Road Initiative advocated by China is expecting to assist in the infrastructure and financing of participating countries and promote free trade through cooperation with countries along the Belt and Road. China hopes to lead the regional economic integration process through investment-driven trade. Out of geopolitical considerations, Russia and India initially held a relatively negative or cautious attitude towards the Belt and Road Initiative. Therefore, Russia proposed the concept of the Eurasian Economic Union (EEU) in 2011 in order to unite the other independent ASEAN countries based on the customs alliance consisting of Russia, Belarus, and Kazakhstan, and thus create a supranational consortium, which in turn have the ability to compete and cooperate with the Belt and Road Initiative proposed by China. In 2014, India launched the Indian version of the Belt and Road Initiative, named Project Mausam, expecting to promote the integration of economic and trade exchanges around the Indian Ocean with India as the center. However, after recent strikes by the trade war, China actively seeks assistance from India and Russia in order to break through the US trade blockade. During the G20 summit held in Japan in June 2019, China, India, and Russia held a three-party talk. After the talk, the three countries issued a joint statement claiming that “they shall undertake more global responsibilities to protect the fundamental and long-term interests of the three countries themselves and the world”, which seems to have opened up opportunities for future cooperation among the three countries. Therefore, this paper explores the competitive and cooperative relationship among China, India, and Russia under the Belt and Road Initiative.
The Effect of Workplace Spirituality on Innovative Work Behavior
Authors: Ranasinghe Vimansha R. , Samarasinghe Samantha M.
Published: November 2019

Workplace spirituality is a novel concept and it has been identified as a unique way to improve organizational performance. On the other hand, many organizations are experiencing undesirable consequences of lack of workplace spirituality, such as employee stress, turnover, absenteeism, and lack of employee creativity. Hence, organizations are now focusing on developing workplace spirituality in the workplaces as it offers many advantages to organizations. Despite the growing interest on workplace spirituality, there is still a dearth of research on the topic of workplace spirituality. Literature suggests that employee innovative work behavior directly leads to enhance organizational performance and workplace spirituality leads to increase innovativeness and creativity of employees. Hence, the purpose of this paper is to fill the gap in literature, to a certain extent by proposing a conceptual model to examine the effect of workplace spirituality on employee innovative work behavior. Thus, it proposed that there is a positive effect of workplace spirituality on employee innovative work behavior. Consequently, intrinsic motivation from componential theory of creativity was integrated to identify the mediating effect of intrinsic motivation on the effect of workplace spirituality on innovative work behavior.

Authors: Kintu Ismail , Buyinza Faisal , Kiwala Yusuf
Published: November 2019

Using the 2013 World Bank Enterprise Survey Data for Uganda, this paper employs the logit and quintile estimation technique to explain the relationship between tax administration and entrepreneurial performance among SMEs in Uganda. The study also employed interviews to obtain expert opinion about tax administration and also explain the results of logit models. Our results indicate that tax rate positively and significantly affect entrepreneurial performance, while tax administration has no effect on entrepreneurial performance. Other key factors that promote entrepreneurial performance include access to credit, firm age, male ownership, training and participation in exporting. Our results suggest that efforts to incentivize and set a conducive tax rate, ease of access to financing and training need to be strengthened for higher entrepreneurial performance among SMEs in Uganda.

Published: November 2019

Virtual Reality (VR) is an upcoming trend in games and entertainment applications as the use of head-mounted displays becomes accessible for the mass market. These systems aim to provide immersive experiences, but they still do not provide a completely seamless experience, mostly due to sickness symptoms that can be experienced by the players. Cybersickness (CS) is one of the most critical problems that make the game industry fearful for higher investments. In this work, we made a critical study on the theories and causes of CS in virtual environments. We unified in a paper most of the leading hardware and software proposals to identify, quantify and minimize the main sickness problems. We also provide clarification about the most relevant measurement tools used to quantify the level of sickness for one or more players through specific questionnaires. We also developed a demo plugin for a commercial game engine to collect relevant data in a VR game to use as a database to future research approaches to enhance user experience in head-mounted displays.

Authors: TIAN Minglei , YAN Xuemin , XIAO Wei , LIN Liangwen
Published: November 2019

An experimental study on adsorption of phenol and o-cresol using ionic liquid-immobilized silica contained different functional groups was carried out. The effects of various operating parameters such as type of ionic liquid group, different adsorption time and ambient temperatures, different solvents in solid phase extraction (SPE) process and several aqueous ion solutions on adsorption of two phenols had been experimentally investigated. It was found that amino ionic liquid-immobilized silica had the highest adsorption efficiency and stability. The optimized adsorption conditions were 15 min under 35oC. In SPE, the acidity solution such as ethanol-HCl (0.1% vol.) and NaH2PO4 could reduce the adsorption efficiency of sorbents. Finally, the sorbent was applied to determining two phenols in real samples and relative standard deviation (RSD) less than 6.14% showed the high precision.

Effect of High Density Electric Current Pulse on Solidification of Cu-37.4 wt.%Pb Monotectic Alloy Melt
Authors: MA Teng , GENG Guihong , SUN Xiaosi , HAO Xi , HAO Weixin
Published: November 2019

The effect of high-density electric current pulse (ECP) on the solidification of Cu-37.4 wt.%Pb monotectic alloy melt was investigated. The microstructure formation mechanisms of ECP were clarified according to liquid metal cluster theory. The results demonstrated that with ECP treatment, the microstructure of Cu-Pb monotectic alloy became finer, the distribution of Pb phase in the matrix was more even and the solute trapping was significantly apparent. Based on the metal liquid cluster theory under ECP, the solid solubility increase result might be due to the salvation clusters increase under the action of pulse current, leading to the binding force increase among solute atoms and solvent atoms. Simultaneously, the aforementioned results were verified through the Differential Scanning Calorimetry (DSC) curve analysis. The results of hardness test, anti-friction test and wear- resistance test show that the ECP can enhance the hardness, improve the properties of anti-friction and wear-resistance of the alloy.
Investigation of Surface Quality of CoCrMo Alloy Used in the Tibial Component of the Knee Prosthesis According to the Methods of Turning and Turning-Grinding
Authors: BAHÇE Erkan , GÜLER M. Sami , EMİR Ender
Published: November 2019

CoCrMo alloys, which are well-known Co-based biomedical alloys, have many different types of surface integrity problems reported in literature. Residual stresses, white layer formation and work hardening layers are some those, matters which occur as a microstructural alteration during machining. Therefore, such problems should be solved and surface quality of end products should be improved. In this paper, the surface quality of CoCrMo alloy used in tibial component of the knee prosthesis produced by means of turning was investigated. An improvement was suggested and discussed for the improvement in their machinability with the developed turning-grinding method. Finite element analyses were also carried out to calculate temperature and thermal stresses distribution between the tool and the tibial component. The results showed that many parameters such as cutting speed, feed rate, depth of cut, tool geometry, and tool wear affect the surface quality of workpieces of CoCrMo alloy. In the turning-grinding method, the machining time is reduced by about six times compared to machining only method. The EDX analysis performed on the surface after machining showed that metal diffusion occurred from tool to the tibial component.

Authors: Schmidt Dennis , Zureck Alexander , Gradetzki Stefanie , Seel Gennadij
Published: November 2019

The desire of audiences to consume content in a series format, independent of time and place has increased in recent years. Technological advancement has helped this trend progress. In this paper, series are considered as goods whose sales are linked to the degree of viewers’ attention. Thus, the good series operate on two interconnected levels, an economic and an emotional. The decision to invest in the production of another season of a series is intended to increase the number of subscriptions and the associated revenues. Capital market participants are influenced by various emotional biases when making investment decisions under uncertainty. In the context of an event study, it is examined whether announcements of season extensions have a significant influence on the share price of the respective provider. The results show that investors react with a changed investment behavior. Furthermore, findings from the film industry are transferred to series production.
Metadata Revisited: Updating Metadata Profiles and Practices in a Vendor-Hosted Repository
Authors: Carson A.L. , Ou Carol
Published: November 2019

Implemented as a way to host open-access journals, the University of Nevada Las Vegas (UNLV) Libraries institutional repository (IR) expanded into collecting other researcher-created materials, a process that did not always include clear metadata and descriptive guidelines. Series-specific settings, unclear field definitions, and other varying practices created an inconsistent bibliographic database, however, and the unclear field definitions and lack of thorough internal documentation pointed to issues that would need to be addressed if the Libraries wanted to reliably share its IR metadata with its discovery layer and external harvesters and aggregators. To resolve this problem, UNLV undertook a metadata review intended to reconcile the fields used and provide recommendations on vocabularies and standards for capturing metadata. Through a collaborative, iterative process, the Metadata Review Team suggested and implemented changes to the IR’s metadata structures, in consultation with vendor support, resulting in improved descriptive policies for IR resources.
Nimble Collection Development Policies: An Achievable Goal
Authors: Levenson Helen N.
Published: November 2019

This paper identifies and reviews some of the currently relevant components of collection development which contribute to the need for having a written collection development policy (CDP) in place. The requisite elements for a pertinent and usable CDP are identified, keeping in mind the need to customize these policies to each library’s unique needs. A literature review is presented to demonstrate the long-standing purposes of collection development policies (CDPs), quantitative studies of existing CDPs, and some of the inherent drawbacks in the creation and application of these policies. The author presents a case study which demonstrates the processes undertaken to create a CDP for a medium-sized academic library. This includes more current and relevant considerations for a modern day CDP. The paper also includes the best practices identified throughout the policy creation process and which has the potential to be applied to other similarly situated libraries.
Book Review: Collection Development and Management for 21st Century Library Collections
Authors: Szitas Emily
Published: November 2019

Vicki L. Gregory is a well-known academic who has written seven other books describing librarianship and electronic and web resources. This review pertains to the second edition of her 2011 landmark textbook, Collection Development and Management for 21st Century Library Collections, which had been in good company with Peggy Johnson’s Fundamentals of Collection Development and Management and Maggie Fieldhouse and Audrey Marshall’s Collection Development in the Digital Age. Providing a thorough introduction on the management and future of library collections, this text offers practical tools and invaluable advice. The content is geared toward students of information science who are new to collection maintenance and collection development. However, this book would also be beneficial for all levels of practitioners. Gregory clearly describes the useful collection development and maintenance processes that all librarians, whether in the collection manager role or not, would find invaluable.
Book Review: Ethical Questions in Name Authority Control
Authors: Traill Stacie
Published: November 2019

Cataloging ethics have received significant attention in recent years, notably via a series of events and discussions held under the umbrella of the Association for Library Collections & Technical Services (ALCTS) Cataloging and Metadata Management Section (CaMMS) exploring the potential development of a code of cataloging ethics. At the same time, the “critlib” (critical librarianship) movement has grown, creating both virtual and physical spaces for exploring social justice principles in the context of library work. Catalogers have initiated conversations about social justice in metadata work under the “critcat” banner. The publication of Ethical Questions in Name Authority Control is timely in this environment, where both ethics and social justice are leading concerns for many catalogers and metadata professionals.
A travesti, a onça pintada e a sucuri: reflexões sobre regime de visibilidade no Pantanal, MS
Authors: Duque Tiago
Published: November 2019

Este artigo discute regime de visibilidade a partir da experiência de uma travesti que vive na cidade de Corumbá, MS. A cidade fica no Pantanal e faz fronteira com a Bolívia. Por meio de etnografia, percebe-se que a gestão da visibilidade em termos de gênero e sexualidade não deixa passar incólume os códigos e valores da realidade pantaneira, como, por exemplo, a onça pintada e a sucuri, animais espetacularizados pela mídia e hiper valorizados pelos turistas. Esses animais são compreendidos na análise como agindo de forma cultural-natural. Através de referencial teórico multidisciplinar, que vão dos estudos de gênero aos fronteiriços e pantaneiros, a onça pintada e a sucuri são problematizadas como sendo performáticos e protéticos. Os relatos de campo contam sobre a incorporação e a performance da travesti com esses animais em eventos públicos na cidade, como o Amistoso da Diversidade e o Carnaval. Conclui-se que, considerando a realidade fronteiriça e pantaneira, o regime de visibilidade estrategicamente manipulado pela travesti e por outros/as efeminados/as da cidade, os/as colocam em um lugar de reconhecimento social diante de diferentes grupos da cidade, além de produzir uma diferenciação valorativa da identidade nacional diante de um “Outro” desvalorizado.
Perdidos, marginais e exóticos. Narrativas fílmicas e modos de representação de alteridades e fronteiras
Authors: Bessa Karla Adriana Martins
Published: November 2019

O artigo analisa quatro filmes produzidos no Brasil entre as décadas de 1990 e 2010, tendo como fio condutor a questão dos deslocamentos de pessoas, entre Brasil e outros países. As principais questões que norteiam a reflexão dizem respeito a como os filmes produzem um modo de olhar para as alteridades em vista das tensões e conflitos da vida na diáspora. Procura-se na análise destacar tanto os aspectos transnacionais quanto chamar atenção para especificidades locais no que toca às narrativas ficcionais e aos temas gerais que elas mobilizam. A contribuição pretendida é a de abordar a experiência da nossa cultura audiovisual, de modo a indagar sobre nossos modos de espetacularização da autoimagem e daquela que criamos sobre os outros.
Espaços de branquitude: segregação racial entre as classes médias em Salvador, Bahia
Authors: Maia Suzana Moura
Published: November 2019

Neste artigo, examino as formas como uma identidade branca é construída a partir da ocupação de espaços racialmente segregados da cidade de Salvador, na Bahia. Alinhando-me aos estudos críticos de branquitude, busco entender como os mecanismos de aproximação a uma identidade branca e a tudo que a ela é associado funciona como forma de distinção social das classes médias, garantindo-lhes acesso privilegiado a bens e recursos. A partir de pesquisa realizada no Loteamento Aquarius, situado na Pituba, bairro de classe média alta, examino os processos cotidianos de produção de espaços de branquitude, buscando compreender como uma cidade segregada afeta a produção de sujeitos sociais e como estes sujeitos, por sua vez, afetam a construção da cidade. A metodologia da pesquisa, ainda em curso, constitui-se em levantamento de dados secundários sobre a ocupação do espaço urbano de Salvador, e de dados primários, coletados com base em entrevistas semiestruturadas com moradores do bairro, assim como em observações etnográficas e autoetnográficas.
Carolina Maria de Jesus e a literatura marginal: uma questão de gênero
Authors: Silva Eliane da Conceição
Published: November 2019

O objetivo deste artigo é analisar a posição de Carolina Maria de Jesus na chamada Literatura Marginal através de uma análise de sua obra, ressaltando sua importância para o fortalecimento da perspectiva da mulher negra na Literatura Marginal. Ao reconhecermos a relevância de Carolina Maria de Jesus para a Literatura Marginal é possível discutir os entraves para o entendimento de sua escrita, especificamente de uma perspectiva de gênero. Sendo assim, questões de classe, raça e gênero se inter-relacionam e perpassam a obra, expondo os problemas de autonomia, de reconhecimento e de ascensão social para as mulheres negras. Para isso, analisamos o contexto histórico de Carolina Maria de Jesus e sua origem social, procurando ir além do estereótipo de uma mulher negra e pobre que escreve, e que, após a ascensão, se submeteu aos diferentes usos de sua imagem. Por fim, pretendemos mostrar como a escrita de Carolina é referência e inspiração para outras mulheres, uma vez que apresenta o ponto de vista daquelas que são duplamente silenciadas, mas que buscam na literatura o meio para contar suas próprias histórias.
