Relationship between air diffusivity and permeability coefficients of cementitious materials
Authors: Sakai Yuya
Published: September 2020

In this study, the relationship between air diffusivity and permeability in cementitious materials was investigated to theoretically investigate the relationship between diffusion and air permeability coefficients. First, an equation to correlate air diffusivity and permeability in a straight circular tube was derived. Then, existing studies that measured both air diffusivity and permeability and compared reported data were collected and the applicability of the derived equation to cementitious materials was verified. Although a correction factor was not used, the two sets of data showed good agreement quantitatively. This indicates that the derived equation can be applied to cementitious materials including concrete, and measured air diffusivity can be converted to permeability of concrete and vice versa using the derived equation.

Published: September 2020

Background

Internet-based dementia caregiver interventions have been shown to be effective for a range of caregiver outcomes; however, little is known about how to best implement them. We developed iGeriCare, an evidence-based, multimedia, web-based educational resource for family caregivers of people living with dementia.

Objective

This study aims to obtain feedback and opinions from experts and clinicians involved in dementia care and caregiver education about 1 iGeriCare and 2 barriers and facilitators to implementing a web-based caregiver program.

Methods

We carried out semistructured interviews with individuals who had a role in dementia care and/or caregiver education in several key stakeholder settings in Southern Ontario, Canada. We queried participants’ perceptions of iGeriCare, caregiver education, the implementation process, and their experience with facilitators and barriers. Transcripts were coded and analyzed using a grounded theory approach. The themes that emerged were organized using the Consolidated Framework for Implementation Research.

Results

A total of 12 participants from a range of disciplines described their perceptions of iGeriCare and identified barriers and facilitators to the implementation of the intervention. The intervention was generally perceived as a high-quality resource for caregiver education and support, with many stakeholders highlighting the relative advantage of a web-based format. The intervention was seen to meet dementia caregiver needs, partially because of its flexibility, accessibility, and compatibility within existing clinical workflows. In addition, the intervention helps to overcome time constraints for both caregivers and clinicians.

Conclusions

Study findings indicate a generally positive response to the use of internet-based interventions for dementia caregiver education. Results suggest that iGeriCare may be a useful clinical resource to complement traditional face-to-face and print material–based caregiver education. More comprehensive studies are required to identify the effectiveness and longevity of web-based caregiver education interventions and to better understand barriers and facilitators with regard to the implementation of technology-enhanced caregiver educational interventions in various health care settings.

Authors: Chen Sam Li-Sheng , Yen Amy Ming-Fang , Lai Chao-Chih , Hsu Chen-Yang , Chan Chang-Chuan , Chen Tony Hsiu-Hsi
Published: September 2020

Background

Implementing and lifting social distancing (LSD) is an urgent global issue during the COVID-19 pandemic, particularly when the travel ban is lifted to revive international businesses and economies. However, when and whether LSD can be considered is subject to the spread of SARS-CoV-2, the recovery rate, and the case-fatality rate. It is imperative to provide real-time assessment of three factors to guide LSD.

Objective

A simple LSD index was developed for health decision makers to do real-time assessment of COVID-19 at the global, country, region, and community level.

Methods

Data on the retrospective cohort of 186 countries with three factors were retrieved from a publicly available repository from January to early July. A simple index for guiding LSD was measured by the cumulative number of COVID-19 cases and recoveries, and the case-fatality rate was envisaged. If the LSD index was less than 1, LSD can be considered. The dynamic changes of the COVID-19 pandemic were evaluated to assess whether and when health decision makers allowed for LSD and when to reimplement social distancing after resurgences of the epidemic.

Results

After large-scale outbreaks in a few countries before mid-March (prepandemic phase), the global weekly LSD index peaked at 4.27 in March and lasted until mid-June (pandemic phase), during which most countries were affected and needed to take various social distancing measures. Since, the value of LSD has gradually declined to 0.99 on July 5 (postpandemic phase), at which 64.7% (120/186) of countries and regions had an LSD<1 with the decile between 0 and 1 to refine risk stratification by countries. The LSD index decreased to 1 in about 115 days. In addition, we present the results of dynamic changes of the LSD index for the world and for each country and region with different time windows from January to July 5. The results of the LSD index on the resurgence of the COVID-19 epidemic in certain regions and validation by other emerging infectious diseases are presented.

Conclusions

This simple LSD index provides a quantitative assessment of whether and when to ease or implement social distancing to provide advice for health decision makers and travelers.
Intention to use Medical Apps Among Older Adults in the Netherlands: Cross-Sectional Study (Preprint)
Authors: Askari Marjan , Klaver Nicky Sabine , van Gestel Thimon Johannes , van de Klundert Joris
Published: September 2020

BACKGROUND

The increasing health service demand driven by the aging of the global population calls for the development of modes of health service delivery that are less human resource–intensive. Electronic health (eHealth) and medical apps are expected to play an important role in this development. Although evidence shows mobile medical apps might be effective in improving the care, self-management, self-efficacy, health-related behavior, and medication adherence of older adults, little is known about older adults’ intention to use these technologies when needed, or the factors influencing this intention.

OBJECTIVE

The objective of this study was to investigate the relationship of technology acceptance factors and intention to use mobile medical apps among community-dwelling older adults.

METHODS

Data was collected using questionnaires. The factors selected from the literature have been validated using Cronbach α and tested for significance using logistic regressions.

RESULTS

Almost half (49.7%) of the included older adults reported no intention to use medical apps. Adjusted logistic regression analysis per factor showed that the factors Attitude toward use (odds ratio [OR] 8.50), Perceived usefulness (OR 5.25), Perceived ease of use (OR 4.22), Service availability (OR 3.46), Sense of control (OR 3.40), Self-perceived effectiveness (OR 2.69), Facilities (OR 2.45), Personal innovativeness (OR 2.08), Social relationships (OR 1.79), Subjective norm (OR 1.48), and Feelings of anxiety (OR 0.62) significantly influenced the intention to use mobile medical apps among older adults, whereas the factor Finance (OR 0.98) did not. When considered together, a controlled multivariate logistic regression yielded high explained variances of 0.542 (Cox-Snell R2) and 0.728 (Nagelkerke R2).

CONCLUSIONS

The high odds ratios and explained variance indicate that the factors associated with the intention to use medical apps are largely understood and the most important factors have been identified. To advance the evidence base, experimental controlled research should investigate the causality between the factors, intention to use, and actual use. For this purpose, our evidence suggests that policies designed to improve Attitude toward use appear most effective, followed by policies addressing Perceived usefulness, Perceived ease of use, Service availability, and Sense of control.
Noninvasive Real-Time Mortality Prediction in Intensive Care Units Based on Gradient Boosting Method: Model Development and Validation Study (Preprint)
Authors: Jiang Huizhen , Su Longxiang , Wang Hao , Li Dongkai , Zhao Congpu , Hong Na , Long Yun , Zhu Weiguo
Published: September 2020

BACKGROUND

Monitoring critically ill patients in intensive care units (ICUs) in real time is vitally important. Although scoring systems are most often used in risk prediction of mortality, they are usually not highly precise, and the clinical data are often simply weighted. This method is inefficient and time-consuming in the clinical setting.

OBJECTIVE

The objective of this study was to integrate all medical data and noninvasively predict the real-time mortality of ICU patients using a gradient boosting method. Specifically, our goal was to predict mortality using a noninvasive method to minimize the discomfort to patients.

METHODS

In this study, we established five models to predict mortality in real time based on different features. According to the monitoring, laboratory, and scoring data, we constructed the feature engineering. The five real-time mortality prediction models were RMM (based on monitoring features), RMA (based on monitoring features and the Acute Physiology and Chronic Health Evaluation [APACHE]), RMS (based on monitoring features and Sequential Organ Failure Assessment [SOFA]), RMML (based on monitoring and laboratory features), and RM (based on all monitoring, laboratory, and scoring features). All models were built using LightGBM and tested with XGBoost. We then compared the performance of all models, with particular focus on the noninvasive method, the RMM model.

RESULTS

After extensive experiments, the area under the curve of the RMM model was 0.8264, which was superior to that of the RMA and RMS models. Therefore, predicting mortality using the noninvasive method was both efficient and practical, as it eliminated the need for extra physical interventions on patients, such as the drawing of blood. In addition, we explored the top nine features relevant to real-time mortality prediction: invasive mean blood pressure, heart rate, invasive systolic blood pressure, oxygen concentration, oxygen saturation, balance of input and output, total input, invasive diastolic blood pressure, and noninvasive mean blood pressure. These nine features should be given more focus in routine clinical practice.

CONCLUSIONS

The results of this study may be helpful in real-time mortality prediction in patients in the ICU, especially the noninvasive method. It is efficient and favorable to patients, which offers a strong practical significance.
Continuous Classification of Locomotion in Response to Task Complexity and Anticipatory State (Preprint)
Authors: Kazemimoghadam Mahdieh , Fey Nicholas
Published: September 2020

UNSTRUCTURED

Objective: Intent recognition in lower-extremity assistive devices (e.g., prostheses and exoskeletons) is typically limited to either recognition of steady-state locomotion or changes of terrain (e.g., level ground to stair) occurring in a straight-line path and under anticipated condition. Stability is highly affected during non-steady changes of direction such as cuts especially when they are unanticipated, posing high risk of fall-related injuries. Here, we studied the influence of changes of direction and user anticipation on task recognition, and accordingly introduced classification schemes accommodating such effects. Methods: A linear discriminant analysis (LDA) classifier continuously classified straight-line walking, sidestep/crossover cuts (single transitions), and cuts-to-stair locomotion (mixed transitions) performed under varied task anticipatory conditions. Training paradigms with varying levels of anticipated/unanticipated exposures and analysis windows of size 100-600 ms were examined. Results: More accurate classification of anticipated relative to unanticipated tasks was observed. Including bouts of target task in the training data was necessary to improve generalization to unanticipated locomotion. Only up to two bouts of target task were sufficient to reduce errors to < 20% in unanticipated mixed transitions, whereas, in single transitions and straight walking, substantial unanticipated information (i.e., five bouts) was necessary to achieve similar outcomes. Window size modifications did not have a significant influence on classification performance. Conclusion: Adjusting the training paradigm helps to achieve classification schemes capable of adapting to changes of direction and task anticipatory state. Significance: The findings could inform control strategies for assistive devices to robustly deal with “unknown” perturbations providing increased levels of safety and reliability.
Food expenditures and consumption by food bank clients in Silicon Valley
Authors: Robinson Courtney N. , Baker Gregory A. , Harwood Michael J. , Diekmann Lucy O.
Published: September 2020

Food insecurity is a pervasive problem in the United States and it is particularly acute in high cost areas. This study focuses on the diets and food expenditures of food bank clients in two Northern California counties located in what is commonly known as Silicon Valley. The results indicate that the study group spent 27% more than the federal government’s Thrifty Food Plan, but consumed a lower amount of fruits, vegetables, protein, and dairy than what is needed for a healthy diet. Policies that encourage better nutrition and more balanced diets at affordable prices and which take into account the living and transportation situations of food insecure populations are needed to address these issues.
Determinants of sustainability assurance levels: The case of French firms
Authors: Klibi Emna , Damak-Ayadi Salma , Dridi Sinda , M’Zali Bouchra
Published: September 2020

The aim of this work is to analyse the determinants of the level of sustainability assurance for the CAC 40 French firms from the time period preceding and following the implementation of the Grenelle 2 law that made sustainability assurance compulsory. The objective of the paper is twofold: 1) provide a better understanding of the factors influencing the professional judgement provided by assurance providers, 2) verify whether the content of the disclosed sustainability reports has evolved as a result of the introduction of the Grenelle 2 law or not. A sample of 257 firm-year observations is collected for the period 2008-2017 and an ordinal regression model is used in this study. The findings highlight a change in the content of assurance reports after the promulgation of the Grenelle 2 law. The sector’s sensitivity, the type of assurance provider, and the leverage level have an impact on the level of assurance for the period 2013-2017 which was not the case for the period 2008-2012. Based on the institutional theory, these correlations may be explained by the promulgation of the Grenelle 2 law in 2012.

Published: September 2020

OBJECTIVE
Disruption of rest-activity rhythms is cross-sectionally associated with
metabolic disorders, including type 2 diabetes (T2D), yet it remains unclear whether
it predicts impaired glucose metabolism and homeostasis.
The aim of this study is to examine the cross-sectional and prospective
associations between rest-activity rhythm characteristics and glycemic measures
in a cohort of older men.

RESEARCH DESIGN AND METHODS Baseline rest-activity rhythms were derived from actigraphy using
extended cosine model analysis. Fasting glucose, insulin and
homeostasis
model assessment of insulin resistance (HOMA-IR) were measured from fasting blood at
baseline and after ~3.5 years. T2D were defined using self-report, medication
use and fasting glucose.

 RESULTS In the cross-sectional analysis (n=2,450), lower 24-hour amplitude:mesor ratio (i.e.,
mean-activity-adjusted rhythm amplitude) and reduced overall rhythmicity, were
associated with higher fasting insulin and HOMA-IR (all p-trend < 0.0001), indicating increased insulin resistance. The
odds of baseline T2D were significantly higher among those in the lowest
quintile of amplitude (OR Q1 vs Q4 (95% CI), 1.63 (1.14, 2.30)) and
late acrophase group (OR late vs normal (95% CI), 1.46
(1.04, 2.04)). In the prospective analysis (n=861), multiple rest-activity
characteristics predicted a 2-3 fold increase in T2D risk, including a lower
amplitude (OR Q1 vs Q4 (95% CI), 3.81 (1.45, 10.00)) and
amplitude:mesor ratio (2.79
(1.10, 7.07), reduced overall rhythmicity (3.49 (1.34, 9.10)), and a
late acrophase (2.44
(1.09, 5.47)).

CONCLUSIONS Rest-activity
rhythm characteristics are associated with impaired glycemic metabolism and
homeostasis and higher risk of incident T2D.
A multifunctional role of Leucine-rich-alpha 2 glycoprotein 1 in cutaneous wound healing under normal and diabetic conditions

Published: September 2020

Delayed wound healing is
commonly associated with diabetes. It may lead to amputation and death if not
treated timely. Limited treatments are available partially due to the poor understanding
of the complex disease pathophysiology. Here, we investigated the role of
Leucine-rich alpha-2-glycoprotein1 (LRG1) in normal and diabetic wound healing.
Firstly, our data showed that LRG1 was significantly increased at the
inflammation stage of murine wound healing, and bone marrow-derived cells served
as a major source of LRG1. LRG1 deletion causes impaired immune cell
infiltration, re-epithelialization and angiogenesis. As a consequence, there is
a significant delay in wound closure. On the other hand, LRG1 was markedly
induced in diabetic wounds in both humans and mice. LRG1-deficient mice were
resistant to diabetes-induced delay in wound repair. We further demonstrated
that this could be explained by the mitigation of increased neutrophil
extracellular traps (NETs) in diabetic wounds. Mechanistically, LRG1 mediates
NETosis in an Akt-dependent manner through TGF-beta type I receptor kinase ALK5.
Taken together, our studies demonstrated that LRG1 derived from bone marrow
cells is required for normal wound healing, revealing a physiological role for
this glycoprotein, but that excess LRG1 expression in diabetes is pathogenic
and contributes to chronic wound formation.

Indigenous Small-Numbered Peoples of the North Yakutia During the Great Patriotic War (the case of the Tomponsky District)
Authors:   North-Eastern Federal University, Sivtseva Saassylana Innokentyevna
Published: September 2020

The present study considers the state of the traditional farming, the living conditions and demographic situation of the Evens and the Evenks in the Tomponsky District of Yakutia during the Great Patriotic War. The case of the district under consideration may help to evaluate the situation in the whole Northern Yakutia. The author comes to conclusion that methods applied in the collective farm management in the Tomponsky District were the same as in other districts of Yakutia. Thus, it was prohibited to slaughter for meat the deer population that was in private hands, while the population of collective farm herds was uncontrollably growing. The peoples used to survive due to side jobs on construction sites, engagement in carrier's trade and fur procurement. Hard life and working conditions of the Evens and the Evenks caused the rise in mortality among the indigenous peoples and the excelling rate of reduction of the able-bodied population.
«Letters to the Editor» as a Means of «Renouncing God» of the Soviet Population in the 1920–30s
Authors:   the Church after the Icon  of Holy Mother «Vsetsaritsa», Dimitrovgrad, Guryanov Pyotr Sergeyevich
Published: September 2020

The paper discusses the aspect of the anti-religious struggle of the Bolsheviks in the 1920–30s as ways to destroy the religious consciousness of Soviet citizens in the anti-religious press and, in particular, letters published by non-religious citizens belligerent to religion published on the pages of print media. Insufficient attention of researchers to this issue determines the relevance of the stated topic. Moreover, the use of similar means of influencing public consciousness in the media at present gives the topic a topical character. The study demonstrates how the «Letters to the Editor» of the magazine «Atheist» became a way of constructing, forming the image of the clergy as an enemy of society. Reading the letters of ordinary fellow citizens, the reader identified himself with them, their relationship with the clergy, experienced anxiety associated with the threat to the construction of socialism emanating from the clergy and laity. However, a formal analysis and comparison of letters from both atheists and people of believers made it possible to discover the contradictions and the limits of this means of «renouncing God». Moreover, this approach made it possible to question the authenticity of the «Repentant» letters of church leaders. The main conclusion of the work done is that «Letters to the Editor» was a significant means of «godless» identification of the young, growing population of the country, but an ineffective means of destroying the religious consciousness of believers.

Aesthetic Feelings in the Practice of Personal Evolution in Modern Context
Authors:   Saint-Petersburg State Institute  of Psychology and Social Work, Mishina Irina Vasilyevna
Published: September 2020

The paper focuses on current forms of manifestation of personal aesthetic activity in the modern social and cultural circumstances. Under the conditions of changeability and uncertainty of activity parameters the keenness and contradictoriness of emotional life of a personality are intensified. In this case while determining personal evolution the role of aesthetic emotions, which obtain new important forms of expression, becomes actual. This is revealed in search of correspondence to the demands of aestheticizing of personal image in the meaningful information environment, using aesthetic characteristics in self-appraisal and motivating social activity of a personality. This process can enable formation of inner motives of stability in the unstable world and become an important factor of personal development in various emotional manifestations. The study of the issue requires overcoming limited understanding of personal aesthetic activity and experience, verification of application of notions of aesthetics and practical culturology, expansion the range of phenomena under consideration.
Concepts of χάος, ἀρχή, τo ἄπειρον and the Formation of Apophatic Discourse in Early Greek Philosophy
Authors:   Minin Nizhny Novgorod State  Pedagogical University, Bogomolov Aleksey Vladimirovich , Ryzhova Ekaterina Alekseevna ,   Minin Nizhny Novgorod State  Pedagogical University
Published: September 2020

The paper deals with the apophatic discourse formation in the history of Greek philosophy. The issue of the beginning of negativity is considered. The study highlights the variability of possible answers to this question. The authors of the paper suggest that the beginning of this theme is found at the stage of transition from pre-philosophy to philosophy. The emphasis is on three concepts of early Greek philosophy – Chaos, Arche, Apeiron. In Hesiod’s teachings, Chaos can be interpreted as a pre-philosophical analog of the negative beginning. In the Milesian school, the idea of Arche is formed. Water and air are considered as positive principles. A special place is occupied by the doctrine of Anaximander about Apeiron, which can be represented as the “sublation” of the contradiction between Chaos containing negative characteristics and the positive Original.
Religion in the Post-industrial Society
Authors:   Northern State Medical University, Lavrentyeva Anna Yuryevna
Published: September 2020

Nowadays the institution of religion continues to exist, gradually changing, forming an image that meets requirements of a post-industrial society such as freedom, interest, and the increasing role of information and knowledge. The study shows the impossibility of the rapid transformation of traditional religions as a result of the complexity of religious components (religious consciousness, religious activity, religious relations and religious organizations). The reasons that slow down the evolutionary process of traditional religions in society are indicated. The author’s view on the problem of creating a “new look” by traditional religions is shown. The study gives examples of a religious institution interaction with society through social networks that promote unity, preservation of traditions, the transfer of cultural norms and values, the dissemination of information, and social work. Humanistic approaches that do not deny the importance of religion as a social component, but propose to emphasize the role of traditional religion in the world as a guardian of stability are defined.
Una narración de las fisuras: lo queer de la infancia en la novela V, de Mariana Docampo
Authors: Punte María José
Published: September 2020

La obra de Mariana Docampo se ha ido desplegando desde un primer volumen de cuentos, Al borde del tapiz (2001), hasta su más reciente novela, V (2017), siguiendo una trayectoria que sigue el punteo de ciertas obsesiones. Como los pasos del tango que ella tan bien domina, sus textos hacen un dibujo que adquiere volúmenes en el espacio. Esas derivas hacen visible una cartografía queer, o lo que Elisabeth Freeman denomina una “erotocartografía”. Parte del extrañamiento que producen sus textos, en los que se cruzan desconcertantes preocupaciones por los devenires científicos contemporáneos con sus posibles conexiones cosmogónicas y religiosas, puede tener que ver con una mirada infanceada, una que deforma y desrealiza lo narrado, no tanto a partir del papel (des)configurador de la rememoración, sino de aquello torcido que puede estar radicado en la infancia.

Aim

To describe six cases using the bioprosthetic or native aortic scallop intentional laceration to prevent iatrogenic coronary artery obstruction technique to prevent coronary artery obstruction during transcatheter aortic valve-in-valve procedures.

Methods

All patients presented degeneration of a bovine pericardium bioprosthesis [four Trifecta (19, 21, 23, and 25 mm); two Mitroflow (25 and 27 mm)] resulting in severe aortic stenosis (n = 5) or severe aortic regurgitation (n = 1). Procedures were performed under fluoroscopic and echocardiography guidance, and the transfemoral access was used to deliver a self-expanding valve. Data are expressed as frequency or median (Q1–Q3).

Results

Age, EuroScore II, and Society of Thoracic Surgeons score were 81 years (75–83.2), 2.9% (2.6–10.7), and 2.7% (2.3–3.2), respectively. Median left and right coronary heights were 9.1 mm (6.2–10.3) and 12.4 mm (10–13.5), respectively, with a median virtual transcatheter heart valve-to-coronary distance of 2.9 mm on the left and 4.6 mm on the right side. Isolated left leaflet laceration was planned in four patients, and bileaflet in two. One unsuccessful right leaflet laceration was reported, corresponding to the first patient (success rate 87.5%). All other seven leaflets lacerations were successfully performed, with no intraprocedure complications. No coronary obstruction, in-hospital death, valve complication, cardiovascular event, or pacemaker implantation were reported. All patients are being followed in routine outpatient visits, and no adverse events were registered.

Conclusion

The high procedural success and low complication rate reported in this initial experience, demonstrates that the bioprosthetic or native aortic scallop intentional laceration to prevent iatrogenic coronary artery obstruction technique can be a viable solution to prevent coronary obstruction in selected patients undergoing valve-in-valve procedures. Operator experience, periprocedural imaging and teamwork are essential to enable an accurate and successful procedure.
Pedagogical Tactfulness
Authors: Ljungblad Ann-Louise
Published: September 2020

Situated within the field of inclusive mathematics education, this article presents empirical research from a microethnographic study exploring teacher-student relationships. More specifically, the searchlight was aimed at how math teachers relate to their students when they teach. The classroom study is based on a rich empirical data set collected during a year of field work: video-recorded math lessons, observations and dialogues and interviews in six classes. Four math teachers participated together with 100 students from compulsory school, upper secondary school and schools for children with learning disabilities. Based on a relational perspective on teaching, Pedagogical Relational Teachership, PeRT, (Ljungblad, 2018, 2019) a microanalysis was carried out, about how the teacher’s acknowledgement to students emerged in interpersonal, face-to-face communication. Through a relational turn in mathematics education, exploring interpersonal relationships, an extended relational understanding of situated teaching was acquired. The results illuminated how teachers’ pedagogical tactfulness emerged as a pedagogical fundament in inclusive educational environment. The results also highlighted a moment of specific importance in mathematics education: at that second, when the incalculable (Biesta, 2001, 2007) emerges, the teachers refrain from assessment and, instead, listen and create a space for the students to speak with their unique voices. Over time, such a relational teachership creates trustful and respectful teacher-student relationships.

In this paper, we present the results of the study of the effect of residual La on crystal structure, magnetic properties of La1+dFe11.05Si1.95 (d = 0.00; 0.03; 0.06 and 0.09) compounds. The analysis of X-ray diffractions showed that when the La content increases to 9%, the structure still remains cubic in a typical NaZn13 arrangement with unchanged lattice constant (about 0.5%). All compounds exhibit ferromagnetic - paramagnetic phase transitions. The Curie temperature TC increases slightly from 235 to 245 K.

REPRESENTASI POLITIK PEREMPUAN PARTAI DEMOKRAT DALAM PEMILU LEGISLATIF 2014 DI SUMBAR
Authors: Muwahidah Hanifa
Published: September 2020

Representasi politik perempuan dalam perpolitikan di Indonesia dapat dilihat dalam partai politik yang dimana keterwakilan perempuan  sudah diatur dalam Affirmative action yaitu keterwakilan  30% perempuan dalam partai. Partai politik Demokrat salah satu partai yang sudah memberikan keterwakilan perempuan 30% dalam pencalonan anggota legislatif perempuan dalam pemilu. Pada pemilu 2014 walaupun Partai Demokrat sudah memberikan Keterwakilannya pencalonan perempuan dalam legilatif 30% tetap saja pada hasil Pileg tersebut perempuan tidak memenangkan satu kursi pun dalam DPRD Sumatera Barat tahun 2014. Adapun tujuan dari penelitian ini adalah untuk melihat faktor-faktor yang mempengaruhi Representasi politik perempuan partai politik Demokrat dalam pemilu legislatif  tahun 2014 tingkat Sumatera Barat. Dalam penelitian ini peneliti menggunakan metode Kualitatif dengan pendekatan Studi Kasus. Teori yang digunakan pada penelitian ini rekrutmen politik dari Rush dan Althof dan representasi politik perempuan dari Hanna Pitkin. PenelitiAmelihatAadanya banyak faktor yang mengakibatakan turunnya perolehan suara yang di dapatkan oleh partai politik Demokrat dari pemilu 2009 ke 2014. Yang pertama dilihat dari rekrutmen yang dilakukan oleh partai demokrat, bagaimana representasi politik perempuan dalam partai, Dan adanya 4 faktor yang mengakibatkan hal tersebut, pertama turunnya elektabilitas partai politik Demokrat, yang terjadi diakibatkan habisnya masa SBY dalam pencalonan presiden dan buruknya citra partai demokrat dikarenakan para kader partai politik Demokrat di nasional terlibat kasus korupsi yang dimana hal tersebut membuat masyakarat kurang simpati terhadap partai. Selanjutnya tidak adanya perempuan diberikan no urut partai tinggi dalam dapil yang ketiga kurang aktifnya perempuan dalam berkampanye dan yang terakhir kurangnya sosialsasi tentang pemilu legislatif 2014 dan begitu juga dengan sosalisasi terhadap caleg perempuan.

Introduction: Car painters are routinely exposed to organic solvents classified as carcinogenic and mutagenic substances.
Objective: To characterize the population susceptibility and evaluate the genotoxic effects of exposure to organic solvents.
Methods: A cross-sectional study comparing a group of car painters exposed to organic solvents with a non-exposed group. CYP2E1 polymorphisms and the presence of micronuclei in lymphocytes were determined.
Results: One hundred twenty-two workers participated in the study: 62 who worked in car paint shops and were exposed to solvents, and 60 who were not exposed. There were statistically significant differences between the two groups regarding micronucleated cells and nucleoplasmic bridges frequencies (p=0.042 and p=0.046, respectively; exact likelihood ratio). Significant differences were found at the interaction between the CYP2E1 genotype c1c1 and occupational exposure to solvents, with higher frequencies of micronuclei (p= 0.013) and micronucleated cells (p= 0.015). However, when the frequencies of micronuclei, micronucleated cells and nucleoplasmic bridges in the exposure group were compared between the c1c1 and c2c2/c1c2 allele groups of the CYP2E1 polymorphism, statistically significant differences were found.
Conclusions: This study confirms that when workers with CYP2E1 polymorphisms, specifically the c1c1 genotype, are exposed to organic solvents, they are more likely to have somatic cell mutations, a condition associated with increased susceptibility to diseases such as cancer
Effect size: commentary to the study on the Factors associated with the practice of exclusive breastfeeding
Authors: Angulo-Ramos Marisol , Merino-Soto César
Published: September 2020

This letter focuses on recent and interesting work on breastfeeding, to emphasize two observations. The first observation refers to the fact that, in Mateus and Cabrera’s manuscript  It was hardly discussed whether the referred knowledge and skills may be relevant to understanding the mothers’ behavior regarding their commitment to breastfeeding. The relevance of these cognitive aspects requires more attention due to their relationship with breastfeeding practices, and in general with the long-term mother-infant dyad.
Because the knowledge and skills to maintain successful breastfeeding have implications for developing instructional content in interventions for mothers as well, great attention needs to be paid to the size of the effect of differences between reported frequencies in pregnancy and the immediate puerperium. In Table 3, these differences were examined by the McNemar statistical test, which allows obtaining the statistical significance of the rejection of the null hypothesis of no differences. But neither this test nor the size of its p-value inform about the degree or size of the differences. An estimate of the size or magnitude of the differences, represented as point values or confidence intervals (as reported in Tables 4 and 5), tend to better specify tests of statistical significance.
Therefore, we estimate the practical significance of the difference between the percentages obtained in pregnancy and the immediate puerperium for each of the knowledge and basic skills reported in Table 3. With the only numerical data presented in this table, we calculated the McNemar odd ratio (McNemar OR , and standardized difference measures d: d Cox 8 and d probit . These show less bias with their population values in relation to other estimators5. Because they both assume different statistical assumptions e.g., logistic distribution for McNemar OR and d Cox , and normal distribution for d probit , calculating bothwill report the convergence or divergence of these estimates.

Repurposing, Recycling, Revisioning: Pacific Arts and the (Post)colonial
Authors: Anderson Jean
Published: September 2020

Taking a broad approach to the concept of recycling, I refer to a range of works, from sculpture to film, street art and poetry, which depict issues of importance to Indigenous peoples faced with the (after) effects of colonisation. Does the use of repurposed materials and/or the knowledge that these objects are the work of Indigenous creators change the way we respond to these works, and if so, how?
