Interiors, Affect, and Use: How Does an Academic Library’s Learning Commons Support Students’ Needs?
Authors: DeFrain Erica , Hong Miyoung 
Published: June 2020

Abstract
Objective – This study sought to identify the learning needs, satisfaction levels, and preferences of students using an academic library’s learning commons. A particular focus was understanding whether the socio-collaborative environment facilitated by the learning commons was aligned with the institutional objectives of supporting intensive study and scholarly work.
Methods – A mixed methods sequential explanatory study design was used, in which quantitative findings were supplemented by qualitative findings. Data for the study were drawn from 59 hours of observations documenting behaviors of 9,249 individuals, as well as survey responses from 302 students. Three semi-structured focus groups with 10 students were held to discuss and clarify findings.
Results – Behavior mapping and survey data showed that students were largely satisfied with the learning commons and that it was considered a supportive environment for them to complete their stated tasks. Incongruity was observed between the learning commons’ intended and actual use; although 75% of spaces were designated for collaboration, 50% of survey respondents identified independent work as their primary task and 76% of individuals were observed working independently. In focus group discussions, students praised the space for its vibrant ambiance and facilitation of social connections, but acknowledged that more serious study required retreat into quieter spaces found elsewhere in the library.
Conclusion – The learning commons is an important and desirable space for students, providing a safe and community-oriented environment that is located in the center of campus. While students deemed the atmosphere successful for fostering social relationships and creating an overall sense of belonging, care needs to be taken to maintain a proper balance between quiet and collaborative spaces. The methods used in this study underscore the importance of gathering data from multiple sources, offering guidance to other libraries seeking to create, re-envision, and assess their learning spaces.

Purpose: The article aims to analyze human security issues in the Citarum river basin, Indonesia, by taking the threat of flood in the Majalaya District as a case study. As the case has been increasing in recent years, wave the flood has become an inevitable source of fear for people living in the Citarum river basin in the rainy season. Environmental pollution due to massive industrialization, land function change, especially in the upstream area, and the absence of proper disaster mitigation from local government are problematized in this research.
Methodology: Using the Human Security point of view, the article tries to show people’s perspectives in defining security and overcoming threats, especially relating to flood in the Citarum river basin. As for the method, the research uses a qualitative approach with a study case as an analytical strategy. We interviewed some informants who live in Majalaya District and found secondary data from the government’s and society’s documents and analyze it by using the Human Security approach.
Principal Findings: This article shows how the society’s recognition and feeling on the environmental threat and organizes a limited community-based disaster mitigation system, which is called the ‘JagaBalai’ community, as an effort to build internal resilience and to overcome the risk and fear coming from the flood.
Implications/Applications: The findings of this research contribute to the literature on Human Security concerns, especially those related to its elements of freedom of fear related to natural disasters or any other environmental issues.
Novelty/Originality of this study: The current study fills the gap in the existing body of literature by analyzing the dynamics between an individual’s perspective and the state as a source of security in the Majalaya District, Indonesia, by using Human Security approach. This approach can be useful to describe the degree of disaster victims’ perceptions of fear and security and their relationship to government policies.

RESUMOA partir dos estudos desenvolvidos pelo americano William Labov, em meados da década de 1960, a língua passou a ser concebida como um sistema heterogêneo e susceptível de mudança. Desses achados linguísticos, emergiu a teoria da Variação Linguística, cuja essência é a proposição de que a língua varia de acordo com vários fatores linguísticos e sociais, entre eles o tempo, o espaço e contexto de uso. Sob essa perspectiva, o presente artigo relata a aplicação de uma sequência didática como parte de uma proposta intervencionista aplicada numa turma de 6º ano do ensino fundamental de uma comunidade majoritariamente rural do município de Icapuí, litoral extremo Leste cearense, no último bimestre letivo do ano de 2015, em consonância com a proposta do Programa de Mestrado Profissional em Letras. Objetivava-se com essa parte do trabalho de dissertação a conscientização dos discentes sobre o reconhecimento da variação linguística diafásica. Para alcançar esse intento, foi proposta uma atividade de interpretação de um conto de nossa autoria, cujo enredo trata acerca da necessidade de se adequar as variantes linguísticas de acordo com o contexto interacional. Usamos como fundamentação teórica, Bagno (2007), Bortoni-Ricardo (2004, 2005, 2014), Bortoni-Ricardo e Oliveira (2013), Brasil (1998), Goffman (2013), Tarallo (2007), Thiollent (2009) e Weinreich, Labov e Herzog (2006). Com a aplicação da sequência didática, os resultados obtidos foram satisfatórios, uma vez que foi apresentada e compreendida, integralmente, a abordagem da Variação Linguística Diafásica por meio da interpretação do enredo de contos, conforme as respostas dos discentes nos revelam.
(RE)Descobrindo o Brasil: as relações estéticas entre Blaise Cendrars, Oswald de Andrade e Tarsila do Amaral
Authors: Bisio de Araujo Natalia Aparecida 
Published: June 2020

A viagem de Blaise Cendrars ao Brasil, em 1924, marcou a história das relações entre a estética de Vanguarda, representada pelo poeta franco-suíço, e a Modernista, sobretudo, a de Oswald e de Tarsila. Tal evento inspira Feuilles de Route (1924), de Cendrars, Pau-Brasil (1925), de Oswald e em várias telas de Tarsila. Nesse contexto, os artistas recolhem elementos para suas obras à medida que estudavam mais a fundo as terras brasileiras em uma viagem que fizeram juntos pelo país. O objetivo principal deste trabalho é examinar as relações estéticas entre as obras dos três artistas. A análise se dará por meio de teorias e críticas da poesia; do estudo da modernidade, da vanguarda e do modernismo brasileiro; e de obras que relataram a história da relação entre os artistas.

Published: June 2020

Introduction: Medical students are experiencing uncertainty in finding the appropriate help for their mental health problems. When they finally decide to seek help, some of them are already in a mental crisis. The suitable indicator for early identification of mental disorder is mental health literacy. Mental health literacy also functions as a tool to decrease stigma towards people with mental illness and to improve help-seeking behavior. The purpose of this study is to determine the influence of mental health literacy to help-seeking behavior and to describe mental health literacy and help-seeking behavior of the medical students.Methods: The study design was observational analytical. Participants filled demographic data and answered questionnaire via an online file sharing platform. The questionnaires used in this study were Mental Health Literacy Scale (MHLS) and Attitudes Toward Seeking Professional Psychological Help Short Form (ATSPPH-SF). The influence of mental health literacy to help-seeking behavior was analyzed using logistic regression analysis. Results: The respondents were 60 medical students. No differences of literacy and attitude were found across the admission years. Overall, the students had good literacy and attitude. Students showed lower scores in the MHLS attributes containing ideas about self-treatments, confidentiality, social distance, and reliance on self. Being literate in the total score of MHLS did not influence on having a good attitude in ATSPPH-SF (p=0.303). Only by being literate in attitudes that promote recognition and help-seeking, the students showed a good attitude in ATSPPH-SF (p-value=0.027). Conclusion: There was no influence on mental health literacy to help-seeking behavior.

Published: June 2020

Case:
We report on 2 patients who developed avascular necrosis (AVN) of the talus and poor patient outcomes after undergoing calcium phosphate injection into talar dome bone marrow lesions.

Conclusion:
Subchondroplasty, defined as calcium phosphate injection for the treatment of articular bone marrow edema, is a recently described procedure for use in the ankle joint. In our opinion, the limited available research is of poor quality and describes equivocal improvement in patient symptoms after this procedure. Given the debilitating outcomes and extensive AVN we observed in 2 patients, we strongly advise caution in the use of this procedure in the talus.

Published: June 2020

Students are a component of the education system. It will not be called education if the student is not in it. To succeed in education (learning), many conditions must be considered; one of which is ethics or manners. In the context of Islamic education, ethics or manners for a student is very important. It is difficult for a student to succeed in education if he is not ethical or civilized. Even if he succeeded in education or in learning, then his knowledge was not a blessing or not useful for others or a cause of destruction for himself. This paper aims to describe the ethics of a student who is learning according to the perspective of a religious figure so that he is successful in his learning. This paper used documentary techniques. The data of this paper obtained from the recordings of lectures delivered by Kiai Haji Muhammad Zaini during his lifetime and juxtaposed with the book read by him. Student ethics according to Kiai Hajj Muhammad Zaini is that a student should always expect and ask his teacher to always pray for him, use the time for useful activities, repeat lessons at home and ask back to the teacher related lessons that are still vague for him, clean the intention when looking for knowledge that is only because of Allah SWT, revive religion, keep the Islamic shari'a in order to remain there, intend the knowledge gained will be practiced, always do good deeds and adorn themselves with praiseworthy qualities, get used to getting up at night to worship Allah and ask Allah in order to give him useful knowledge and other virtues, respect his teacher zahir (external) and bathin (inner), not make friends or be close with people who are not in good morals (immoral perpetrators and other deeds), do not use the knowledge they get to debate or pilgrimage, always trying to be close to Allah SWT, accustom to ablution before learning, always reading the Qur'an, always correcting the five senses of sin in order to quickly understand the science of religion.

Abstract
Calcite (CaCO3) is one of the most common scales in oilfield, and its formation can cause a decrease in production. Pressure drop can cause the pH and calcite saturation index (SI) to increase, similarly increase in temperature increases calcite SI. We have developed a new approach to simulate the water composition (e.g., TDS, Ca, and alkalinity) for laboratory tests with ScaleSoftPizer (SSP) software based on desired temperature, pH, and SI. The evaluation of calcite formation and inhibition in the laboratory is also a challenge because the release of CO2 gas increases the pH and saturation index (SI) of the solution, and must therefore be controlled. Accordingly, this study aimed to develop a new and well-controlled test method for calcite inhibition under simulated oilfield conditions (i.e., pH, SI, Ca/HCO3 ion ratio). A new rapid kinetic turbidity method was developed in a closed system for calcite inhibition study. Good consistency was obtained for triplicate calcite nucleation and inhibition experiments, which demonstrated the reproducibility of the new method. Calcite nucleation experiments were conducted, and a new calcite nucleation model is proposed. The effect of acetic acid and inhibitors on calcite kinetics was also evaluated with this new method. This is the first time to accurately measure calcite inhibition under a broad range of production conditions, especially under neutral-to-acidic conditions (pH = 5.5-7), using simple and low-cost kinetic turbidity test methods. By avoiding the release of CO2, this new laboratory test method strictly controls pH, SI, and Ca/HCO3 ion ratios, and thereby the field conditions for calcite scales can be accurately simulated. In addition, barite inhibition experiments were conducted, and inhibition models for eighteen different inhibitors were determined and put onto a self-consistent algorithm, with many practical advantages: speed, reliability, internal consistency, and relative effectiveness for common conditions, to mention a few. Finally, a protocol has been developed to characterize the inhibition of essentially any new inhibitor, or combination, with minimal to no testing.

Abstract
Calcium Sulfate (CaSO4) is precipitated due to super saturation of Ca2+ and SO42-ions that can be created due to change pH, pressure, temperature or due to mixing of the brines. Among the CaSO4 species, CaSO4.2H2O or gypsum is stable in solid phase at lower temperature below 50 °C which has been observed frequently in wells treated with CO2 flooded-EOR technique. As a result, mineral scaling, especially calcium sulfate (gypsum) deposition has been a serious flow assurance problem in oil and gas production leading to production shut down because of formation damage or equipment failure. Use of scale inhibitors may be the efficient method to prevent the scale formation. However, there is a knowledge gap on types of scale inhibitor that might be efficient in controlling the calcium sulfate scaling under varied field conditions. Additionally, there is a need of an efficient method to evaluate the performance of scale inhibitor and simulate the dynamic field condition.
This study provides information on several options of inhibitors to control CaSO4 at various conditions as established with modified laser-light based Kinetic Turbidity Test (mKTT) method that can assess several samples over a range of concentrations simultaneously. Other newly developed modified Continuous Stirred Tank Reactor (mCSTR) method showed to be an efficient tool to understand scale inhibitor performances, as it can overcome limitations of dynamic scale loop (DSL) with low residence time and low volume capacity of capillary tubing. Similarly, as minimum effective dosage (MED) needed can be easily established in one setting with mCSTR method. It showed much better efficiency compared to that of standard bottle test, which suffers lack of dynamics and multiple bottle tests needed to establish MED. This study provides more effective test methodologies for scale inhibitors performance testing. The mCSTR apparatus can be used for various mineral scales such as barium sulfate, halite, calcite, etc. Additionally, this study will provide a mathematical model (scaling risk-inhibitor dosage recommendation) via mCSTR method which can be used to predict scaling tendency and inhibitor need under desired conditions.

Abstract
Scale inhibitor (SI) analysis is an extremely important part of scale management and it is essential to have reliable methods for the accurate and precise measurement of scale inhibitor residuals in produced fluids in order to prevent wells from scaling. This information enables key decisions on the efficiency of scale squeeze and continuous chemical injection treatments especially in remote environments.
In remote fields, such as in desert and extreme winter environments, the ability to be able to monitor scale squeeze residuals on-site would offer significant potential to improve scale management capability through provision of rapid data which otherwise might not be available for several weeks due to long sample transport times to the laboratory.
Since conventional scale inhibitor analysis methods are not suited for on-site analysis this has led to the development of a toolbox of technology options including suitable scale inhibitor squeeze chemistry coupled with advanced, on-site, "near on-line" scale inhibitor detection procedures including Fluorescence (F) and Time Resolved Fluorescence (TRF).
In this paper, two field examples for on-site TRF analysis of polymeric scale squeeze inhibitors from remote wells in harsh environments will highlight the benefits of quick and timely scale inhibitor residual information. In the example from remote desert wells, a comparison of TRF and High Performance Liquid Chromatography (HPLC) analysis of the polymer residuals will show the accuracy and precision of the TRF method at low SI levels.
In addition, an example for the proof of concept of detection of three different F Tagged sulphonated polymers in the presence of a phosphonate squeeze inhibitor and continuously injected untagged polymer will demonstrate the ability of "near on line" fluorescence techniques to improve scale management where four subsea wells are co-mingled in the same flow line.
This paper concludes that fluorescence techniques are particularly suited to tagged polymers and naturally fluorescent molecules whereas Time Resolved Fluorescence provides the ability to detect untagged scale inhibitors like sulphonated copolymers, phosphonates and phosphate esters. The two techniques can be used individually or in combination with each other and, in addition, offer the advantage of being able to detect polymeric and phosphonate scale inhibitors to minimum inhibitor concentration (MIC) of 1-2ppm and &lt;1ppm respectively which offers potential to extend treatment lifetimes.
Closing the Loop – Deploying Reservoir Analysis & Novel Downhole Diagnostic Technology Utilizing Coiled Tubing for Scale Identification & Treatment Leads to Production Revival in HPHT Gas Well
Authors: Hamid Saad , G Herrera Carlos , Ahmed Usman 
Published: June 2020

Abstract
Scale deposition is one of the most common challenges encountered in oil and gas wells. Mature fields tend to have these issues, but tackling scale removal requires tedious diagnostic and intervention work due to uncertainty in determining the exact location and source of scale.
Production decline was observed in a High-Pressure High Temperature (HPHT) gas producer. Well testing was performed to assess and diagnose the production impairment. The preliminary well test data interpretation highlighted positive skin which needed to be characterized. Scale and even sand were considered as a possible cause of production impairment due to the nature of production chemistry and reservoir type, but the hypothesis lacked physical evidence in the wellbore.
A structured approach was adopted to identify, qualify and rectify the situation. High Pressure Coiled Tubing (HPCT) technology capable of providing real time down hole communication was utilized along with coiled tubing mounted downhole camera (DHC) to determine if the wellbore conditions were contributing towards the production decline resulting in a positive skin. The real time images acquired during the downhole camera run revealed astonishing details of the scale that was causing an impact in the production and the flowing wellhead pressure. The high-resolution images obtained during the well intervention clearly pin-pointed at the root cause of production loss and aided in designing a focused treatment for the challenge at hand. Given the sensitive nature of reservoir and possible interaction between the scale dissolving chemicals and reservoir, a customized treatment was formulated. The treatment design exploited the benefits of scale dissolution while preventing reservoir damage. The treatment was pumped using coiled tubing with a high-pressure jetting and rotating nozzle to ensure 360 degree wellbore coverage.
The well was opened to flow immediately after execution of the treatment. The post treatment flowback results indicated a resounding success with production almost quadrupling. A production log was subsequently performed to understand and gauge reservoir performance. The results of production logging further endorsed the fact that skin damage due to scale had been successfully removed and wellbore skin was reduced.
