A Review of:
Ackerman, E., Hunter, J. & Wilkinson, Z. T. (2018). The availability and effectiveness of research supports for early career academic librarians. The Journal of Academic Librarianship, 44(5), 553-568. https://doi.org/10.1108/ILS-09-2016-0068
Abstract
Objective – To identify the type and efficacy of research supports currently available to early career academic librarians.
Design – Survey.
Setting – The United States.
Subjects – 213 academic librarians who were not yet promoted or have received tenure, or those up to three years post-tenure or promotion.
Methods – The researchers created a survey containing 39 closed and open-ended questions using the software Qualtrics. The question types included multiple choice, Likert scale, and free text. The survey was distributed through direct emails and various professional electronic mailing lists.
Main Results – The majority of respondents listed finding time as the most significant barrier to conducting research. Respondents listed informal mentoring as the most commonly used and most widely available form of research support. Statistical analyses revealed that for every type of research support a librarian engaged in, on average confidence increased by 0.10.
Conclusion – Engagement in formal and informal research supports may influence early career academic librarians’ confidence levels in regards to conducting research projects. Academic institutions as well as professional organizations should ensure that ample opportunities are available.

Authors: Belice Tahir , Demir Ismail , Yüksel Arif 
Published: June 2020

Background and Objectives: With this study, for the first time among patients diagnosed with COVID-19, the neutro- phil-lymphocyte-ratios of men and women were compared.
Materials and Methods: The study was conducted with 80 patients and the data was gained retrospectively on the electronic documents of the hospital.
Results: The neutrophil-lymphocyte-ratio was statistically significant and higher in the male than the women for all ages and geriatric patients (p<0.05).
Conclusion: The higher neutrophil-lymphocyte-ratio in older males diagnosed with COVID-19 could be a causative reason for the higher mortality rates in men. We hope that these findings would be helpful for further studies.

Background: Neural tube defects (NTDs) are among the second most common serious birth defects and constitute a major cause of infant death. Research about NTDs has achieved tremendous progress over the last 50 years. Methods: Visualization analysis has been used to explore the hot topic and their emerging trends in NTDs research domain. The scientific literature of research for NTDs has been retrieved from Web of Science™ Core Collection (1966–2014) databases, and final acquire 9125 related bibliographic records, then analyze time trend, distribution of journals, hot keywords, and try to explore the hot topic and their emerging trends in NTDs research domain using Histcite and CiteSpace. Results: The number of publications about NTDs have shown an increased tendency over the last 50 years although there was on a slight decline. Birth Defects Research Part A published the most articles on NTDs research, followed by Lance and Teratology, and the Lancet had the greatest number of total citations. The largest cited frequency keywords was the “Folate”, followed by “Pregnancy”, “Prevention”, and “Spina bifida”. The research hotspots in NTDs research were homocysteine, anencephaly, and screening. Conclusion: With the help of visualization analysis, we explore a quantitative and efficient way of understanding the NTDs knowledge field.

Survey of undergraduates’ perceptions of experiential learning in the MPharm programme: The TELL Project
Authors: Jacob Sabrina A. , Boyter Anne 
Published: June 2020

Objective: To determine the perception of undergraduate pharmacy students of their experiential learning (EL) placements both in the community and hospital settings.
Methods: A cross-sectional survey was conducted utilizing a six-item online survey consisting of one open-ended and five closed-ended questions, the latter utilising five-point Likert-type scales ranging from strongly disagree (1) to strongly agree (5). All undergraduate pharmacy students from the School of Pharmacy (N=496) were included in the study. Survey questions assessed students’ perceptions on the effectiveness of the EL, tutors and placements sites, and organisation and structure of the EL. Thematic content analysis was performed on the open-ended comments, where relevant themes were generated.
Results: From the 139 responses (response rate: 28%), 121 responses were analysed, and of these, 72.5% already had part-time jobs in community pharmacies. Close to 85% felt that their part-time work should contribute to EL hours, which is currently not recognised by the university. Respondents were positive about the effectiveness of EL in developing their professionalism and communication (M=3.84, SD=1.05), clinical (M=3.42, SD=1.22), and technical skills (M=3.32, SD=1.25) Respondents provided favourable feedback about their experience in the hospital as it gave them a real-world exposure to the role of a hospital pharmacist. Community placements were not viewed favourably and this was mainly attributed to the poor experience with tutors whom they felt used them as an extra pair of hands. This was thought to impede their learning experience. They also felt that hospital placements were of insufficient duration, reported by 72.5% of respondents. Respondents also felt they should be sent to other sites such as primary care for placements.
Conclusions: Tutor-training is key to ensure tutors are aware of the responsibilities and expectations. Similarly, quality assurance measures should be adopted to ensure tutors and placement sites are capable of providing students with an effective placement experience. While placement durations are a concern, the focus should be on the quality of the placement experience, and ensuring there is structure and flexibility. Content changes are also needed to include emerging placement sites such as primary care to prepare students for evolving pharmacist roles in the changing healthcare system.
AS reflexões do estagiário sobre a aula de língua portuguesa
Authors: Teixeira Patricia Soares Batista , Barbosa Marinalva Vieira 
Published: June 2020

Neste artigo analisamos a escrita produzida em relatórios de estágio sobre a aula do professor de língua portuguesa visando compreender a natureza da reflexão empreendida pelo estagiário, a partir daquilo que registrou, sobre a aula de língua portuguesa. O propósito é saber como essa escrita está fundamentada, se com argumentos baseados na própria experiência, ou se está apoiada numa espécie de senso comum sobre a docência na educação básica. Para tanto, analisamos como o licenciando realiza o trabalho de “escuta” da aula, considerando que escutá-la está para além de descrever em detalhes os acontecimentos discursivos que se desenvolvem nesse espaço, mas é também percebê-la como espaço de interação entre sujeitos singulares. As análises se sustentam no conceito de análise linguística de Geraldi (2006) que propõe uma compreensão das ações que se fazem com a linguagem por meio das atividades, epilinguísticas, linguísticas e metalinguísticas. O corpus é constituído por excertos de relatórios de estágio supervisionado dos cursos de Letras de duas instituições da rede federal de ensino.

O corpus analítico se compôs de uma matéria de capa da Revista do Correio, ano 12, número 613, parte adjacente do jornal Correio Brasiliense do dia 12 de Fevereiro de 2017. A análise feita nos remete a uma compreensão político-ideológica, que revela conflitos da luta do grafite na busca por lugar nas artes e na sociedade. Palavras chave: Discurso; Grafite; Cultura.
Corpo performático: uma análise discursiva sobre a mulher no contexto publicitário machista
Authors: Lemes Fabiane 
Published: June 2020

Neste artigo, discutimos a objetificação e a subjetificação da mulher enquanto corpo do afazer doméstico pelo olhar de uma campanha publicitária. Com base na Análise do Discurso francesa, sob uma perspectiva interdisciplinar possível pela Linguística Aplicada, objetivamos analisar como a mulher foi discursivizada nessa materialidade, a qual foi criada e divulgada em 2013, nas redes sociais, e se apropriou do contexto relacionado ao futebol para fazer uma analogia entre a torcida feminina e a masculina. Cogita-se verificar a partir de que perspectiva a empresa se inspira ao voltar-se para lugar social ocupado pela mulher nos dias atuais, aquela que trabalha fora e, mediante resquícios do discurso machista o qual ainda vigora, sente-se e é vista por considerável parte da sociedade enquanto responsável pelos afazeres domésticos. Apropriamo-nos dos aportes teóricos de Michel Foucault e Michel Pêcheux no intuito de analisarmos as condições de possibilidade, as regularidades enunciativas e as estratégias linguísticas das quais emergem efeitos de sentido machistas. Nossa análise nos permite afirmar que as campanhas publicitárias selecionadas corroboram o discurso machista ao refutarem a igualdade entre homens e mulheres no papel social de torcedor e ao atribuírem à mulher a responsabilidade pelos afazeres domésticos.

Comparison of Two SEM-EDX Methods for the Analysis of Produced Water Scale Filter Papers
Authors: Jordan Myles , Buckman Jim 
Published: June 2020

Abstract
Low-vacuum scanning electron microscopy (SEM) / energy dispersive x-ray (EDX) analysis can be used to characterize the nature of inorganic scale from produced water (Method 1); routinely used to visually determine the degree, form and composition of scale particulates. Quantitative data on scale coverage can be extracted through image analysis, and morphology can indicate origins of particulates (transported scale, active scale…). Recent trends demand more detailed quantitative analysis, believed to produce more accurate / reproducible results. Such a method is automated SEM-EDX particle analysis (Method 2). This has the advantage of full automation and delivers quantitative data on scale coverage, composition, shape and size. Neither method is perfect, the first relies on experienced SEM users, is a manual method, susceptible to bias, and is often perceived as producing qualitative data, while the second method although producing large quantitative data sets, depends upon the criteria used to classify particles, and can be time consuming. Both methods were used to examine a number of filtered produced water samples. The traditional manual method provides good representative results on scale coverage, details on particulate morphology and composition, and can be undertaken in about thirty minutes per sample; it is also a simple matter to differentiate between particulate and blanket scale deposits. The second method generates superior levels of quantitative data, but results are dependent on image thresholding (for particle selection), erroneous misleading results are all too easily obtained (unless rigorously tested particle classification schemes are used), and the method can take in excess of an hour per sample. In general Method 1 should be adequate to track scale issues from produced water, which can be supplemented where desired by automated particle analysis (APA). Where APA is to be used it is recommended that an industry standard classification criterion be developed, which will increase the degree of confidence that can be applied to results, and allow direct comparison of results between laboratories.
Scale Prediction and Management for Unconventional Production

Published: June 2020

Abstract
Horizontal drilling and hydraulic fracturing have unlocked tremendous hydrocarbon resources in unconventional reservoirs. Production from unconventional plays has become critical and been prioritized in many E&P companies’ portfolio. This paper presents the uncertainty, challenges, and findings in scale prediction and management in such unconventional production. A brief conceptual model is built and utilized to demonstrate the complexities, stages, and impacts in scale management for unconventional production. While a complete list of factors impacting unconventional scale management are reviewed, our two field case studies are focused on factors/aspects that differentiates unconventional fields from conventional fields in terms of scale management. In the first case study, the impact of field fluid residence time on scale inhibitor treatment is investigated and discussed. In the second case study, we conducted extensive field sampling and root cause analysis of the FeS scale formation in an unconventional field and discussed its potential impact and the recommended FeS scale management strategies. This paper demonstrates a comprehensive and integrated approach to appropriately assess and manage scale risk for unconventional horizontal well production, which can be of critical importance to improve reservoir and well performance and improve return on investment (ROI) in unconventional plays.
Squeeze Design Optimization by Considering Operational Constraints, Numerical Simulation and Mathematical Modelling

Published: June 2020

Abstract
The application of chemical scale inhibitors (SI) in a squeeze treatment is one of the most commonly used techniques to prevent downhole scale formation. This paper presents a sensitivity analysis of the treatment design parameters, to assist with the automated optimization of squeeze treatments in single wells in an offshore field.
Two wells were studied with different constraints on total SI neat volume (VSI) and total injected volume (VT) including main pill and overflush volumes, followed by a field case squeeze optimization to demonstrate the sensitivity to lifetime and the cost function per treated volume of water. A purpose-designed squeeze software model was used to simulate the squeeze treatments and perform the sensitivity analysis. In the course of this optimization procedure, a "Pareto Front" is calculated which represents cases that cannot in principle be improved upon. An analysis of these results also shows that this Pareto Front can be generated by a semi-analytical method, as shown for the first time in this paper.
It was demonstrated at fixed values of VSI and VT (resulting in almost a fixed total cost for squeeze), the squeeze lifetime can be improved by increasing the scale inhibitor concentration in the main treatment slug; however, the increase in squeeze lifetime is greatly reduced at very high concentrations. Four generic scale inhibitors were used with different adsorption isotherms to validate these calculations. In cases where either VSI or VT is fixed, it is shown that the squeeze life does not monotonically increase by the other parameter and the cost function can be used to determine the optimum design.
Well squeeze optimization was performed and these recommendations were applied in the field. It was shown that a well-executed sensitivity study can prevent misleading results that miss the global optimum. A lesson learned was that the optimal designs entail injecting as much of the inhibitor as possible as early in the squeeze design as possible - provided formation damage effects are avoided. Also, our semi-analytical construction of the Pareto Front greatly helps to simplify and streamline the overall squeeze optimization process.
Iron Sulfide Scale Inhibition: Limitations at Sour Conditions
Authors: Alduailej Yaser K. , Sorbie Kenneth S. 
Published: June 2020

Abstract
Sour oil and gas production is commonly associated with sulfide scaling challenges originating from the produced aqueous phase. Iron sulfide (FeS) is one of the most common sulfide scales, and recent studies have shown promising dispersant chemicals are available to mitigate its deposition. In addition, successful applications have been reported in the literature, particularly from the North Sea. However, some of the limitations of these FeS chemical dispersants become evident under more severe (high H2S) sour conditions, such as those found in the Middle East, Russia and Canada.
The dispersant efficiency depends on the scale particle size, and larger particle sizes usually require higher dispersant dosages. Other factors that may influence the inhibitor dosage include reactant concentrations (cations and anions), pH, salinity and inhibition time. These factors were investigated using a newly developed anaerobic experimental setup that allows the careful addition and withdrawal of fluids from a closed anoxic system. Anaerobic vessels, such as vials and tubes, are deployed equipped with septa (thin membranes). Syringes were used to infiltrate the septum with minimal interference from sulfide retention while maintaining isolation from atmospheric oxygen.
Testing was performed over a sulfide concentration range from 100 to 1,000 mg/L. Higher levels of sulfide required higher loadings of scale inhibitor, essentially as a result of particle size increase. In addition, varying the salinity also had a significantly influence on the required dispersant concentration to maintain FeS suspension in solution. At lower pH condition, smaller FeS particles were produced and often inhibition was somewhat obscured by solubility effects. Also, suspending the FeS for longer periods of time required higher dispersant concentrations.
More severe sour conditions exceeding 1,000 mg/L of aqueous sulfide, have a detrimental effect on the both the efficiency and economics of the FeS inhibition treatments. In addition, the current high- performance dispersants cannot be squeezed into tight formations or shales, as their high molecular weight may cause severe formation damage. For such applications, alternative inhibition methodologies are required, and non-chemical inhibition may be considered.
Iron Sulfide Scale Inhibition: Squeeze Life Extension Through Improved Interaction Between Scale Inhibitor and Rock

Abstract
Iron sulfide deposition is a ubiquitous phenomenon in sour oil and gas wells and presents unique challenges for its control and management downhole. The majority of current FeS anti-scale chemical technologies tend to be ‘reactive’ rather than ‘proactive’ for downhole scale mitigation, and currently there are few FeS scale inhibitor squeeze options available. The following paper details work performed to modify an existing novel and unique sulfide scale inhibitor to further enhance its sulfide scale inhibition efficacy and to reconfigure the polymer molecule structure for improved adsorption / desorption behavior sufficient to allow squeeze application for control and mitigation of FeS scale downhole.
All new polymeric inhibitor chemistries were tailored for high total dissolved solid (TDS) and high downhole temperature chalk sour gas well application. Further ranking was performed via automated static adsorption tests, iron sulfide efficacy tests and high calcium brine compatibility jar tests to identify the best squeeze applicable candidates for final formation damage coreflood testing.
Introduction of new anchor group functionality into the polymer resulted in improved adsorption behavior (identified via the static adsorption test), while having minimal impact on the inhibitors high TDS / high calcium brine tolerance and also on its FeS scale inhibition performance. The kinetic adsorption study showed &gt; 2 mg inhibitor/g rock adsorption on field analogous chalk rock, which is markedly higher compared to the original parent sulfide inhibitor molecule or other new polymeric variants synthesized without the new anchor groups. FeS scale inhibitor adsorption was further improved by optimizing the ratio of monomer and functional groups on the polymer. Simulated field squeeze coreflood testing revealed no appreciable formation damage to outcrop core analogue under simulated field application conditions and the new variant inhibitor chemicals also showed significant useful adsorption/desorption behaviour.
The new polymeric scale inhibitors are suitable for both continuous injection and squeeze application for control of FeS scale in high temperature and high calcium ion sour gas chalk wells. For squeeze application, testing revealed a low formation damage potential combined with significant chemical retention for potentially extended squeeze lifetime in the field. Ultimately this technology heralds a new era in downhole scale management for sour producer wells plagued by FeS scale via reduction of treatment frequency for assured well integrity.
