A mini review of construction and demolition waste management in India
Authors: Faruqi M Humam Zaim , Siddiqui Faisal Zia
Published: April 2020

The growth of the Indian construction sector is expected to result in a significant demand–supply gap with respect to construction materials such as sand, limestone, and aggregates. Additionally, the vast quantity of unprocessed Construction and Demolition (C&D) waste pose serious problems in some places, particularly in residential, institutional, industrial or commercial construction hotspots. While several waste quantification methodologies have been proposed in the literature, the quantification of waste generation in India is inadequate. This inadequacy can be attributed to the lack of appropriate hierarchical control mechanism, absence of a common C&D waste estimation method, and the lack of C&D waste processing knowledge among generators, collectors, operators, regulators, and the general public. The C&D Waste Management Rules 2016 were introduced to ensure organized collection, storage, transportation, treatment/processing, and disposal of C&D waste in India and fix responsibilities of all stakeholders for management of C&D waste. This comprehensive research attempts to analyze the existing legislation and challenges, and proposes an information framework for organized collection, storage, treatment/processing, and disposal of C&D waste. The C&D waste processing mechanism, potential application of recycled C&D waste products, its limitations, and the best practices of C&D waste management in India are important constituents of the proposed framework.
Impacts of non-oxidative torrefaction conditions on the fuel properties of indigenous biomass (bagasse)
Authors: Shehzad Muhammad , Asghar Anam , Ramzan Naveed , Aslam Umair , Bello Mustapha Mohammed
Published: April 2020

Biomass is considered as the largest renewable energy source in the world. However, some of its inherent properties such as hygroscopicity, lower energy content, low mass density and bio-degradation on storage hinder its extensive application in energy generation processes. Torrefaction, a thermochemical process carried out at 200–300°C in a non-oxidative environment, can address these inherent problems of the biomass. In this work, torrefaction of bagasse was performed in a bench-scale tubular reactor at 250°C and 275°C with residence times of 30, 60 and 90 mins. The effects of torrefaction conditions on the elemental composition, mass yield, energy yield, oxygen/carbon (O/C) and hydrogen/carbon (H/C) ratios, higher heating values and structural composition were investigated and compared with the commercially available ‘Thar 6’ and ‘Tunnel C’ coal. Based on the targeted mass and energy yields of 80% and 90% respectively, the optimal process conditions turned out to be 250°C and 30 mins. Torrefaction of the bagasse conducted at 275°C and 90 min raised the carbon content in bagasse to 58.14% and resulted in a high heating value of 23.84 MJ/kg. The structural and thermal analysis of the torrefied bagasse indicates that the moisture, non-structural carbohydrates and hemicellulose were reduced, which induced the hydrophobicity in the bagasse and enhanced its energy value. These findings showed that torrefaction can be a sustainable pre-treatment process to improve the fuel and structural properties of biomass as a feedstock for energy generation processes.
Empathy with Emerging Generations as a Foundation for Ministry
Authors: Argue Steven C. , Greenway Tyler S.
Published: April 2020

Ministry leaders’ concerns for young people’s spiritual and religious lives often lead them to adopt programmatic solutions in order to remain relevant to emerging generations. We speculate that a more foundational shift is needed. We argue that ministry leaders can support the spiritual quests of young people by reconsidering their teaching and learning assumptions, renewing their empathy skills, and reframing their assumptions about who young people are and what they truly need.
Systematic Review on the Use of the Children’s Depression Inventory-2 Among Hispanics
Authors: Cumba-Avilés Eduardo
Published: April 2020

We systematically reviewed studies reporting the use of the Children’s Depression Inventory-2 (CDI-2) in samples with at least 30 children and significant Hispanics enrollment (≥14.5% of the sample and at least 20 Hispanics completing the scale). We grouped studies by form (short or full-length) and language used, developmental stage, report of psychometric data (particularly for Hispanics), and other characteristics. From 252 full-texts revised, 22 met selection criteria. Six reported psychometric data for Hispanics, either for the English full-length (α = .86–.92) and short form (α = .76–.81) or for the Spanish short form (α = .69–.80). Criterion-related validity was supported via correlation/regression or comparing group means, but not using another depression self-report scale. Current knowledge on the CDI-2 psychometrics among Hispanics is mostly based on studies with the English-language version. No study has reported the psychometrics of the full-length Spanish-language CDI-2 with Hispanics.

Authors: Fakih-Gomez Nabil , Steward Enosh , Orte Aldea Maria del Carmen
Published: April 2020

Several reports have been published wherein intradermal filling with nanofat has been used for skin rejuvenation, texture improvement and scar treatment. A study was conducted between August 2017 and August 2018 which included 20 female patients having wrinkles, hyperpigmentation, erythema, and enlarged pores. Lidocaine cream, local infiltration with lidocaine or sedation was used in accordance with the patient’s convenience. Nanofat was injected intradermally in all the facial regions. All patients filled a questionnaire at sixth month post treatment which consisted of questions regarding pain, bumps area and resolution, grade of improvement of skin (wrinkles, smoothness, wrinkles, pores and redness), recovery of donor area, time to reincorporate to normal routine, nanofat-time efficacy and recommendation of the treatment. Patients undergoing it with sedation had less bruising and pain. Lateral thigh as the donor area had less pain in the recovery period. The residual bumps persisted for more time in non-mobile areas while average time to disappear was 3.6 weeks. Patients started to notice the change after nanofat injections at about 1.12 months later. The improvement was noticed for smoothness of skin (100% patients), wrinkles (40% patients), pore size reduction (15% patients), improvement in redness (10% patients). The effect of nanofat was felt by patients for an average time of 3.85 months. All the patients were satisfied and recommended it. No major complications were reported. Nanofat treatment is safe and it conveys beneficial effects on skin rejuvenation as per the post-operative skin texture changes and the satisfaction of patients.

Published: April 2020

Today, an advanced wound dressing with the ability of blood clotting and antibacterial activity is the main subject of many studies to consider their necessity in modern society. In this study, it was aimed to present a novel scaffold with both abilities simultaneously. Poly(vinyl alcohol)/poly(lactic acid) nanofibrous scaffolds containing ceftriaxone antimicrobial agent (PVA-CTX/PLA) and tranexamic acid coagulant (PVA-CTX-TXA/PLA) were fabricated by electrospinning method. Morphology, antimicrobial activity, blood coagulation and bioavailability indexes, and swelling ability (gel formation) of produced samples were determined. Morphological results showed that the hybrid nanofibers were form successfully. The antibacterial efficiency of them against Gram-negative ( Escherichia coli) and Gram-positive ( Staphylococcus aureus) bacteria was more than 90% for PVA-CTX/PLA and it reached 100% for PVA-CTX-TXA/PLA. Both PVA-CTX-TXA/PLA and PVA-TXA/PLA scaffolds showed acceptable blood coagulation ability with an average absorption of 0.043 and 0.036 nm, respectively. PVA-CTX-TXA/PLA scaffolds had a gel formation ability of about 45 min. All scaffolds were successful in cell proliferation (L929 fibroblast cell) after 48 h.
Understanding the Effects of Perpetrators’ Aggressiveness and Victim-Related Factors on Sexual Revictimization: Stepwise GLM Analysis of the 2010 NISVS
Authors: Park Seong-min , Monaghan Heather
Published: April 2020

Studies on sexual revictimization have employed two distinct approaches: perpetrator-oriented and victim-oriented approaches. Although the former posits that sexual revictimization is associated with perpetrators’ aggressiveness and victim–offender proximity, the latter focuses on the effects of victims’ situational and behavioral factors. In addition to these conflicting approaches, studies have grappled with the fact that a large number of respondents have not experienced victimization, thereby impacting the analytical strategies that should be used. This study uses the data from the National Intimate Partner and Sexual Violence Survey and employs stepwise zero-inflated and non-zero-inflated methods to examine the impact of perpetrator-oriented and victim-oriented approaches on sexual victimizations that occur by force and those that occur due to incapacitation while taking into consideration that the majority of respondents have not experienced the victimizations under study. Findings show that both perpetrator-oriented (particularly aggressiveness) and victim-oriented factors impact sexual revictimization. The implications of the findings and the limitations of this study are discussed.
Correlates of Fear of Victimization Among College Students in Spain: Gender Differences and Similarities
Authors: León Carmen M. , Fikre Butler Leah , Aizpurua Eva
Published: April 2020

Past studies that have analyzed fear of victimization using samples composed of men and women have most frequently controlled for the effect of gender. This study not only controls for the effect of gender, but also examines how the predictors of fear of victimization may vary across gender. To do so, separate regression models for men and women were estimated and the corresponding z tests were calculated for the purpose of analyzing whether the differences between genders were significant. The results showed that women scored higher on the general fear of crime victimization scale, as well as for fear of becoming victims of each of the specific crimes under study. Religiosity had an equally significant effect on men and women’s fear of victimization. Also, younger participants were more likely to fear being victims in the cases of both men and women, although this effect was even more pronounced among women. In addition, respondents’ fear of victimization differed across gender based on sexual orientation. Finally, the results showed a few variables (political orientation and sexual victimization) that were only significant in the case of women, but not of men. The findings of this study confirm that fear of victimization and its predictors vary between women and men.
The Impact of Sexual Arousal and Emotion Regulation on Men’s Sexual Aggression Proclivity
Authors: Craig Amber N. , Peterson Zoë D. , Janssen Erick , Goodrich David , Heiman Julia R.
Published: April 2020

Extant literature supports a relationship between sexual arousal and increased likelihood of sexually coercive behavior in men. The present study investigated the impact of sexual arousal on sexual coercion proclivity and the degree to which emotion regulation moderated this relationship in the context of two separate affect inductions. We predicted that sexual arousal would more strongly predict sexual coercion likelihood for men scoring lower on emotion regulation ability compared with men with above average emotion regulation abilities. Male participants with ( n = 38) and without ( n = 40) self-reported histories of sexual coercion were recruited from urban sexually transmitted infection testing clinics. Participants completed a measure of emotion regulation, underwent a positive and negative affect induction, viewed an erotic video, and reported on their level of sexual arousal immediately prior to completing a hypothetical sexual coercion likelihood laboratory task. Relationships between emotion regulation, sexual arousal, and sexual coercion likelihood were examined using moderation analyses. Sexual arousal was associated with greater reported sexual coercion likelihood. For men with poorer emotion regulation, sexual arousal significantly and positively predicted sexual coercion likelihood in the positive affect condition. Sexual arousal did not significantly predict sexual coercion for men with above average emotion regulation. Findings may have implications for the assessment of individual risk for coercive sexual behavior as well as primary prevention efforts.
Reactions to Participating in Trauma and Addiction Research Among Women in a Sober Living Home: A Brief Report
Authors: Edwards Katie M. , Siller Laura , Murphy Sharon B.
Published: April 2020

The purpose of this study was to examine reactions to participating in trauma and addiction research among women in a sober living home. Participants were 59 women who completed a comprehensive survey battery while living in the sober living home. The survey assessed women’s victimization and addiction history along with current psychological and behavioral health symptoms and resilience characteristics. At the end of the survey, women were asked about their reactions to participating in the survey. Results suggested that whereas 40.7% ( n = 24) of women reported being upset immediately after completing the survey, 96.6% ( n = 56) of women reported that they personally benefited from being in the research study. Women who reported being upset, compared with those who were not upset, had higher levels of depressive and posttraumatic stress disorder (PTSD) symptoms and housing and financial instability and lower levels of empowerment, posttraumatic growth, and sense of purpose. We also asked women to tell us, in their own words, their reasons for being upset (e.g., questions about victimization experiences, loss of children), as well as their reasons for benefiting (e.g., catharsis/venting, learning something new about oneself, the chance to meet the researcher who had nice qualities). In general, the research was well tolerated by most of the participants, and almost all women, including those who were initially upset, reported personal benefits. These data shed light on the factors associated with positive and negative emotional reactions to research participation, which could be important information to include in consent forms in future research with this population.
The Failure of Gender Equality Initiatives in Academia: Exploring Defensive Institutional Work in Flemish Universities
Authors: Roos Hannelore , Mampaey Jelle , Huisman Jeroen , Luyckx Joost
Published: April 2020

Although a large number of studies have explored the main causes of gender inequality in academia, less attention has been given to the processes underlying the failure of gender equality initiatives to enhance gender representation, especially at the professorial level. We offer a critical discourse analysis of recently promulgated gender policy documents of the five Flemish universities, and demonstrate that defensive institutional work is a fundamental process underlying resistance to gender equality in the academic profession. That is, powerful organizational actors resist gender change by (un)intentionally deploying a combination of discursive strategies that legitimate what we describe as non–time-bound gender equality initiatives: The expected outcomes are undetermined in time, and they delegitimate concrete, time-bound measures that define specific outcomes against well-defined deadlines. By explicitly bringing a temporal dimension into our analysis, we argue that defensive institutional work deflects questions regarding what ought to be achieved when, and contributes to the slow pace of gender change in academia.
On instability of constitutive models for isotropic elastic-perfectly plastic material behaviour at finite deformations
Authors: Trajković-Milenković Marina , Bruhns Otto T , Zorić Andrija
Published: April 2020

The main goal of this work is to test the possibility of a newly introduced constitutive law to model the behaviour of the isotropic elastic-perfectly plastic material which is exposed to large elastoplastic deformations. The proposed constitutive relation is based on the hypo-elastic relation and the inelastic INTERATOM model. The verification of the model is done by its implementation into the commercial software ABAQUS/Standard via the user subroutine UMAT. For that purpose, the large simple shear problem is studied where selected objective corotational rates, i.e. the logarithmic rate, the Jaumann rate and the Green-Naghdi rate, are individually implemented in the aforementioned constitutive relations. The obtained results are compared mutually and with the relevant literature. The proposed constitutive model is also used to test the behaviour of the part of a real engineering structure, i.e. a seismic isolator, in order to obtain the correct input data for further analysis of superstructure behaviour due to seismic excitation.
Influence of concrete age on the behavior of ultrasonic waves in interfaces (concrete–steel–concrete)
Authors: Raach Y , Derouiche Y , Messelmi F
Published: April 2020

This paper presents the influence of the composite age on the variation of the transmission and reflection coefficients. The composite is the concrete in our case. The studied structure is a multilayer structure composed of two elastic and isotropic layers where each one is characterized by its own physical properties. The problem is simplified in two-dimensional plane waves, and the influence of the attack angle on the acoustic impedances is also examined. Moreover, an experimental study is realized in the formulation of concrete and the measurement of waves propagation velocity. In this work, during the concrete formulation, three different types of concrete were developed: sand concrete, ordinary concrete, and high-performance concrete. The results of simulation and experiments demonstrate that the age of concrete and the internal concrete structure have a direct influence on the evolution of the acoustic parameters as well as the angle of incidence, which has considerably changed the behavior of the transmission and reflection coefficients. This internal structure is directly related to the age of the concrete where its maturity is not reached until after a certain age, which influences the behavior of the waves through the layers of the multilayer structure.
Magneto-hydrodynamic (MHD) micropump of nanofluids in a rotating microchannel under electrical double-layer effect
Authors: Kumar Mondal Pranab , Wongwises Somchai
Published: April 2020

We investigate the electroosmosis of nanofluid in a rotating microfluidic channel under the influence of an applied magnetic field. We bring out the rotation-induced complex flow dynamics in the channel as modulated by the nanoparticle driven modifications in the viscous drag. In particular, we observe the flow reversal at the center of the channel, emerging from an intricate competition among different forcings under consideration. We identify the critical rotation Reynolds number, signifying the critical strength of channel rotation relative to the viscous resistance to the flow, for which the flow reversal at the channel center sets in. We demonstrate that the strength of the flow reversal for higher rotation Reynolds number decreases, since higher rotation Reynolds number breaks the interparticle interactions, leading to an enhancement in the effective viscosity of the fluid. Finally, we explain the consequential effects of colloidal suspensions of nanoparticle as realized through the particle concentration and agglomeration size on the alterations in the volume transport rates in the channel.
A review of neuropsychiatric adverse events from topical ophthalmic brimonidine
Authors: Cimolai N
Published: April 2020

Brimonidine is a first-line topical medication for increased intraocular pressure and glaucoma which may be used alone or in conjunction with other topical therapies. Its structural and pharmacological comparabilities to clonidine give way to the hypothesis that it may cause neuropsychiatric side effects. The majority of case reports citing brimonidine toxicity, either for topical or peripheral exposure, include pediatric age groups but especially infants. Among the latter, a dose-response phenomenon is evident. Dose-response correlates have also been shown among adults. Case series and prospective double-blind treatment studies also give evidence for the occurrence of several central nervous system adverse reactions. Topical ophthalmic brimonidine use should be followed for the occurrence of neuropsychiatric disturbances generally, and enhanced vigilance should be maintained for at-risk populations.
Edward Harrison (1759–1838): An overlooked advocate of EcoHealth and One Health in the early 19th century
Authors: Morley Neil J
Published: April 2020

Edward Harrison (1759–1838) was an English doctor best known for his ground-breaking treatments of spinal deformities and his failed attempts at medical reforms in the early 19th century. However, with the encouragement of his patient and patron Sir Joseph Banks, he also undertook comparative research on the influence of environmental factors on infectious diseases of medical and veterinary importance using approaches that were forerunners of the modern-day concepts of EcoHealth and One Health. His works in this field, particularly his study of sheep rot, are highlighted.
Non-technical skills in operating room nursing: Ethical aspects
Authors: Hanssen Ingrid , Smith Jacobsen Inger Lise , Skråmm Sisilie Havnås
Published: April 2020

Background

Non-technical skills are cognitive and interpersonal skills underpinning technical proficiency. Ethical values and respect for human dignity make operating room nurses responsible for nursing decisions that are clinically and technically sound and morally appropriate.

Aim

To learn what ethical issues operating room nurses perceive as important regarding non-technical skills.

Research design

Qualitative individual in-depth interviews were conducted. The interviews were analysed using Braun and Clarke’s six phases for thematic analysis.

Participants and research context

Eleven experienced perioperative/operating room nurses working in an operating unit at a Norwegian university hospital.

Ethical considerations

Approval was given by The Norwegian Social Science Data Service in care of the hospital’s Data Protection Officer.

Findings

Three main themes were found: respect and care for the patient, making the patient feel safe, and respect within the perioperative team. These features or themes, which incorporate collaboration and communication, are closely connected to patient safety.

Discussion

Defending the patient’s dignity is part of caring for and respecting the patient. The manner in which the operating room team collaborates is important for the patient to feel safe and secure. Poor teamwork may have dire consequences. Reciprocal respect within the team includes respect for each other’s tasks and responsibilities and to talk to one another in a friendly manner.

Conclusion

Being respectful and contributing to a caring atmosphere are central ethical skills in the operating room. To patients, harmonious teamwork translates into a feeling of safety and being cared for. The nurses see respect and patient safety, and respect and reciprocal politeness among the members of the perioperative team as central ethical non-technical skills. Lack of respect influences the team negatively and is detrimental for patient safety. Good communication is an important safety measure during surgery and creates a feeling of good ‘flow’ within the operating room team.
The EBRD, fail forward neoliberalism and the construction of the European periphery
Authors: Shields Stuart
Published: April 2020

The European Bank for Reconstruction and Development is an institution, a set of programmes and policies designed to mark a number of important reforms not just in the post-Soviet space but in the wider European political economy. It is committed to developing a competitive business environment, foreign investment and private sector activity in the post-communist space. The European Bank for Reconstruction and Development is considered to be a key inter-state mechanism enabling member states to negotiate post-communist reforms. The paper reorients analysis of the European Bank for Reconstruction and Development, claiming that existing framings of the role of the EBRD ignore its tangible neoliberalising pressures. It argues that the EBRD works to fundamentally restructure states in the post-communist space in three ways: (1) the configuration of an ‘appropriately’ neoliberal economic space, (2) the construction of subaltern subjectivities in the regional space, and (3) the persistent dominance of expert knowledge and policy practice external to the state. This restructuring is intended to further neoliberalism in the economic space of the region. By uncoupling the European Bank for Reconstruction and Development from a state centric analysis, the paper reveals how the technical aspects of the European Bank for Reconstruction and Development activities configure particular neoliberal rationalities and competencies not as a putative superstate, but as a key site for the ever-deeper encroachment of neoliberalisation in peripheral European states.
The Development and Initial Validation of a Self-Report Job Precariousness Scale Suitable for Use With Young Adults Who Study and Work
Authors: Creed Peter A. , Hood Michelle , Selenko Eva , Bagley Louella
Published: April 2020

Precarious employment has been increasing worldwide. Yet there are few scales suitable to assess it, and no scales to measure perceived job precariousness in working students who are particularly vulnerable. Using classic test theory, we generated 21 job precariousness items and had them reviewed by experts. In Study 1 ( N = 282, 63% female, mean age 22 years), exploratory factor analysis yielded four factors of job conditions, security, remuneration, and flexibility, each with 3 items. In Study 2 ( N = 211, 75% female, mean age 22 years), confirmatory factor analysis confirmed that this four-factor model was the best fit compared to unidimensional, second-order, and bifactor models. Cronbach’s α coefficients for all factors and the full-scale score were sound (all >.78). Validity was supported by showing that precariousness was related negatively to life satisfaction and employer support and positively to job insecurity, financial strain, and subjective social status. Precariousness was unrelated to age, sex, and hours worked. The Job Precariousness Scale has the potential to promote research into the effects of precarious employment on working students’ current and future functioning and achievement and how experiences of precariousness influence the development of a precarity identity.
A Spherical Rendering of Deviant Information Resilience
Authors: Hopp Toby , Ferrucci Patrick
Published: April 2020

This theoretical exploration describes the social and technical features that, together, play a role in the resilience of deviant ideas in contemporary society. It argues, specifically, that two distinct but inter-related spherical processes together contribute to the social persistency of deviant information. The first of these spherical phenomena relates to the fragmentation of the dominant public discussion sphere. The second spherical process of interest relates to information spheres, and specifically as it pertains to a widening of the sphere of legitimate controversy (i.e., the society-wide determination that a topic or object of conversation is worthy of debate). This article argues that these two spherical entities—the constellation of dominate and counter discussion spheres and the information sphere—have a mutualistic and interactive relationship with one another, and that understanding this relationship provides critical insight into the social resilience of deviant information.

Published: April 2020

In this article, we describe how neuroscience can be used in the study of team dynamics. Specifically, we point out methodological limitations in current team-based research and explain how quantitative electroencephalogram technology can be applied to the study of emergent processes in teams. In so doing, we describe how this technology and related analyses can explain emergent processes in teams through an example of the neural assessment of attention of team members who are engaged in a problem-solving task. Specifically, we demonstrate how the real-time, continuous neural signatures of team members’ attention in a problem-solving context emerges in teams over time. We then consider how further development of this technology might advance our understanding of the emergence of other team-based constructs and research questions.
Intraocular schwannoma with extrascleral extension
Authors: Udyaver Sanika , Lim Li-Anne S , Milman Tatyana , Mashayekhi Arman , Shields Jerry A , Shields Carol L
Published: April 2020

Purpose

To report a rare case of intraocular schwannoma with extrascleral extension in a patient with juvenile idiopathic arthritis and to review the literature for this topic.

Methods

Case report.

Results

A 19-year-old male with a history of juvenile idiopathic arthritis was referred for diagnosis and management of an episcleral mass, initially thought to be focal nodular scleritis. The ocular surface of the right eye revealed an elevated amelanotic episcleral nodule inferonasally, with thin strands of overlying sclera, feeding episcleral vessels, and measuring 11 mm × 11 mm in diameter and 5 mm in thickness. Ophthalmoscopic examination revealed a minimally pigmented ciliochoroidal tumor measuring 13 mm in diameter and 11.4 mm in total thickness and without associated subretinal fluid, orange pigment, or drusen. Ultrasound biomicroscopy and anterior-segment optical coherence tomography confirmed a solid mass with scleral disruption and extraocular extension. Shave biopsy revealed palisading spindle cells and interspersed eosinophilic fibrillary cytoplasmic processes, forming Verocay bodies. The specimen stained positive for S-100 and negative for Melan-A, consistent with benign schwannoma. Observation was recommended.

Conclusion

Intraocular schwannoma is a rare, benign uveal tumor that can demonstrate extrascleral extension, mimicking inflammatory and malignant neoplastic processes. Clinical diagnosis is challenging, and tissue biopsy is required for definite diagnosis.
Vitrectomy with the inverted internal limiting membrane flap technique in eyes with full-thickness macular hole and dry age-related macular degeneration
Authors: Michalewska Zofia , Nawrocki Jerzy
Published: April 2020

Purpose

To present effects of the inverted internal limiting membrane flap technique in full-thickness macular holes coexisting with dry age-related macular degeneration.

Methods

Our database was retrospectively reviewed in order to spot patients with the simultaneous diagnosis of dry age-related macular degeneration and full-thickness macular hole. Vitrectomy with the inverted internal limiting membrane flap technique was performed. Inclusion criteria were full-thickness macular hole, drusen, vitrectomy performed, and spectral domain optical coherence tomography (Copernicus HR, Optopol, Poland) or swept source optical coherence tomography (Triton, Topcon, Japan) before surgery, then 1 week (±3 days), 1 month (±1 week), 3 months (±1 month), 6 months (±1 month), 12 months (±2 months), and 18 months to 12 years after surgery.

Main outcome measures

Closure of macular hole and visual acuity at the final control.

Results

A total of 18 eyes of 12 patients (mean age: 68 years) were included. Mean minimum macular hole diameter was 493 μm. Mean maximum macular hole diameter was 1072 μm. Macular hole was closed in 16 eyes after first surgery and in all eyes after second surgery. Improvement of visual acuity was statistically significant ( P = 0.05), but there was no statistical significant correlation observed between initial macular hole diameters and final visual acuity ( P > 0.1).

Conclusion

The inverted internal limiting membrane flap technique improves anatomical and functional results in eyes with coexisting dry age-related macular degeneration and full-thickness macular holes. Final development of choroidal neovascularization or geographic atrophy is possible in rare cases.
Clinicopathological, Treatment and Event-Free Survival Characteristics in a Moroccan Population of Triple-Negative Breast Cancer
Authors: Mouh Fatima Zahra , Slaoui Meriem , Razine Rachid , EL Mzibri Mohammed , Amrani Mariam
Published: April 2020

Introduction:

Triple-negative breast cancer (TNBC) is a group of breast carcinoma characterized by the lack of expression of estrogen and progesterone hormone receptors (ER, PgR) and HER2. This form is also characterized by its aggressiveness, a low survival rate, and the absence of targeted therapies. This study was planned to evaluate the clinical features, treatment, and prognosis characteristics of TNBC in a population of Moroccan patients.

Methods:

In this retrospective study, a total of 905 patients diagnosed with breast cancer at the National Institute of Oncology in Rabat, Morocco, have been included. Based on molecular subtype, patients were divided into 2 categories: TNBC and non-TNBC patients. Data were recorded from patients’ medical files and analyzed using SPSS 13.0 software (IBM).

Results:

Overall, 17% of the patients had TNBC. At diagnosis, the median age of TNBC cases was 47 years, with extreme ages of 40 and 55 years. The median follow-up time was 30 months (10-53 months) and the 3-year survival rate was 76%. No significant difference was observed among the patients in terms of age at diagnosis, age at menarche, age at the time of first birth, nulliparity, oral contraception, and family history of breast cancer. Menopausal status and the number of pregnancy were significantly higher in the non-TNBC group. The percentage of grade 3 (G3) tumors was higher in the TNBC group ( P < .001). Using neoadjuvant, adjuvant chemotherapy and radiotherapy, a net benefit in the event-free survival was registered for the 2 groups.

Conclusions:

This retrospective study was very informative and showed that women with TNBC had a less favorable prognosis than non-TNBC cases. Clinical data demonstrated that risk factors including age, premenopausal status, parity, hormonal contraceptive use, advanced disease, and a high histologic grade were independently associated with TNBC. However, large tumors and high Scarff-Bloom and Richardson grade prevail in TNBC cases with a higher incidence of lymph node metastases.
‘Take a back seat’: White music teachers engaging Hip-Hop in the classroom
Authors: Kruse Adam J
Published: April 2020

With the purpose of exploring how engaging with Hip-Hop might contribute toward decentering Whiteness in US music education, this research aims to understand the perceptions of three White music educators in the United States teaching Hip-Hop in their classrooms comprising majority students of color. The study explores participants’ past experiences with Hip-Hop, their current teaching practices, and the influence that teaching Hip-Hop has had on their role in the classroom. I also engage in critical self-reflection in order to name and disrupt my own White fragility that emerged during the process of conducting the study and writing this article. Analysis reveals that engaging with Hip-Hop does not inherently contribute to decentering Whiteness, and considerations suggest more intentional and explicit work toward these ends.
When journalism and games intersect: Examining news quality, design and mechanics of political newsgames
Authors: García-Ortega Alba , García-Avilés José Alberto
Published: April 2020

The use of games to convey the news involves wrestling with two different narrative logics: the professional culture of journalism, based on the verification of information and the standards of objectivity and truthfulness, and the culture of games, characterized by the creation of imaginary worlds, the persuasive potential of entertainment and the mechanics of the gaming experience. This article examines a sample of eight newsgame designs and the mechanisms through which they transmit information on issues related to political activity. We designed a qualitative analysis tool to examine the journalistic and gaming quality of the newsgames by analysing 28 parameters in four categories: formal parameters, content parameters, quality of use and architecture and design. Our results show that the use of playful elements is compatible with the fulfilment of journalistic quality standards and the choice of mechanics and dynamics determines how the user perceives and interacts with the information. However, the balance between both aspects does not guarantee that a newsgame provides the narrative resources to understand the information autonomously. Thus, newsgames are a genre with great journalistic potential when using the correct choice of mechanics and dynamics that allows communicating information according to news standards.

Health psychology sheds light on the process of returning to work after sick leave and subsequent medical rehabilitation. A 15-month longitudinal study with N = 201 orthopedic rehabilitation patients is reported. It examined whether and how both physiological health (e.g. body mass index and oxygen reabsorption) and psychological/social-cognitive factors (e.g. self-efficacy and social support) are related to returning to work. It was found that social-cognitive and physiological variables, such as oxygen consumption at anaerobic threshold, are important for returning to work. While physical activity was significantly correlated with social-cognitive variables, it was not significantly correlated directly with returning to work. Results suggest that self-efficacy and oxygen consumption at anaerobic threshold should be improved during medical rehabilitation.
Older gay men in Hong Kong and later life concerns: Identities matter?
Authors: Suen Yiu Tung
Published: April 2020

Research on lesbian, gay and bisexual (LGB) ageing has burgeoned in the past decade in Western settings such as Australia, Canada, the UK and the US. Based on the emerging research about older gay men in Hong Kong, this article adds two important aspects to the ongoing agendas for global research into LGB ageing and later life. First, it further conceptualizes and subdivides Hong Kong's older gay men into three subgroups who hold varying levels of salience of sexual identity in their life and thus have different later life concerns. Second, to contribute to the wider LGB ageing research, I argue that at the same single time point, older LGB people in different parts of the world may hold very different understandings of their sexual identity. In some parts of the world, sexual identities may matter less for older LGB people, and thus, such older LGB people may accordingly have very different later life concerns.
Speech-Language Pathologists’ Perceived Competence in Working With Culturally and Linguistically Diverse Clients in the United States
Authors: Parveen Sabiha , Santhanam Siva priya
Published: April 2020

A clinician’s perceived competence determines his or her ability to attain clinical outcomes and persevere through challenging situations. This study examined the perceived competence of 337 speech-language pathologists (SLPs), including monolingual and bilingual, working with culturally and linguistically diverse (CLD) clients within the United States. Results indicated comparable competence levels of both monolingual and bilingual SLPs in their service delivery to monolingual English-speaking clients. However, bilingual SLPs reported significantly higher competency than monolingual SLPs while working with non-English-speaking clients in different areas of service delivery, including speech and language assessment, dealing with challenging clinical situations, and responding to questions regarding intervention outcomes. It is likely that language concordance, awareness, and understanding of linguistic and cultural expectations of non-English-speakers help surpass communication barriers leading to increased perceived competence among bilingual SLPs. This study summarizes persisting challenges in service delivery of CLD populations and possible recommendations for preservice training of SLPs.
Developing a thermo-regulative system for nonwoven textiles using microencapsulated organic coconut oil

Organic coconut oil was investigated as a bio-based phase change material in core, and melamine formaldehyde was used as shell material to fabricate microencapsulated phase change material for thermo-regulation in nonwoven textiles. The microcapsules were synthesized using in situ polymerization method. The produced microcapsules (microencapsulated phase change material) were applied by knife coating in different ratios (1:5 and 1.5:5; MPCM: coating paste by wt.) to 100% polypropylene nonwoven, porous, and hydrophilic layer of a laminated, spunbond, and double-layer fabric. The coated layer was confined within two layers of the fabric to develop a thermo-regulative system on the nonwoven fabric to regulate the body temperature in surgeries. The two layers were composed by applying heat (140°C) and pressure (12 kg/cm2). Organic coconut oil, the fabricated microcapsule, and the composite fabrics were characterized by Fourier transform infrared spectroscopy, differential scanning calorimetry, and scanning electron microscopy. Scanning electron microscopy results revealed that spherical and uniform microcapsules were obtained with an approximate particle size of 2–6 µm. Differential scanning calorimetry results indicated that microencapsulated phase change material and the composite fabrics possessed significant melting enthalpies of 72.9 and 8.4–11.4 J/g, respectively, at peak melting temperatures between 21.6 and 22.8°C within human comfort temperature range. The utilization of coconut oil as a phase change material and the composite integration of this phase change material to a nonwoven fabric bring forward a novelty for future applications.

Death of the ALARA Radiation Protection Principle as Used in the Medical Sector
Authors: Oakley Paul A. , Harrison Deed E.
Published: April 2020

ALARA is the acronym for “As Low As Reasonably Achievable.” It is a radiation protection concept borne from the linear no-threshold (LNT) hypothesis. There are no valid data today supporting the use of LNT in the low-dose range, so dose as a surrogate for risk in radiological imaging is not appropriate, and therefore, the use of the ALARA concept is obsolete. Continued use of an outdated and erroneous principle unnecessarily constrains medical professionals attempting to deliver high-quality care to patients by leading to a reluctance by doctors to order images, a resistance from patients/parents to receive images, subquality images, repeated imaging, increased radiation exposures, the stifling of low-dose radiation research and treatment, and the propagation of radiophobia and continued endorsement of ALARA by regulatory bodies. All these factors result from the fear of radiogenic cancer, many years in the future, that will not occur. It has been established that the dose threshold for leukemia is higher than previously thought. A low-dose radiation exposure from medical imaging will likely upregulate the body’s adaptive protection systems leading to the prevention of future cancers. The ALARA principle, as used as a radiation protection principle throughout medicine, is scientifically defunct and should be abandoned.
Technition: When Tools Come Out of the Closet

People are ambivalently enthusiastic and anxious about how far technology can go. Therefore, understanding the neurocognitive bases of the human technical mind should be a major topic of the cognitive sciences. Surprisingly, however, scientists are not interested in this topic or address it only marginally in other mainstream domains (e.g., motor control, action observation, social cognition). In fact, this lack of interest may hinder our understanding of the necessary neurocognitive skills underlying our appetence for transforming our physical environment. Here, we develop the thesis that our technical mind originates in perhaps uniquely human neurocognitive skills, namely, technical-reasoning skills involving the area PF within the left inferior parietal lobe. This thesis creates an epistemological rupture with the state of the art that justifies the emergence of a new field in the cognitive sciences (i.e., technition) dedicated to the intelligence hidden behind tools and other forms of technologies, including constructions.
