Impact of Physical Activity on Gestational Weight Gain in Overweight
and Obese Pregnant Women: A Meta-Analysis
Authors: Rani Vandana , Kulandaivelan Sivachidambaram , Chaturvedi Rekha , Yadav Ravinder 
Published: March 2021

Background:
Regular physical activity and exercises play an important role in a healthy
pregnancy in overweight and obese women.

Objective:
To investigate the effect of exercise parameters (frequency, duration and intensity) and
Physical Activity (PA) on maternal Gestational Weight Gain (GWG) in overweight and obese pregnant
women.

Methods:
PubMed and Cochrane database were used to locate the literature; randomized controlled
trials comparing PA with standard care on combined overweight and obese pregnant women, published
in English language from January 2011 to March 2020 were selected. PA interventions, including
walking, aerobic and resistance exercise either alone or in combination compared with standard
care during pregnancy in overweight and obese pregnant women were screened. Mean Difference
(MD) with 95% Confidence Interval (CI) between the intervention and standard care for
GWG was calculated.

Results:
Twelve studies with 1667 pregnant women were included. The result showed a statistically
significant reduction of GWG in the PA group as compared to the standard care (MD 0.99 kg,
p<0.00001 & I2=25%). Overweight and obese pregnant women who performed exercises for the duration
of 45-60 minutes/session (MD -1.01 kg, P=0.0008 and I2=61%), a frequency of 3
times/week (MD -1.19 kg, P=0.0002 and I2=58%) and light to moderate intensity (MD -1.37 kg,
P<0.0001 & I2=62%), reported good weight control during pregnancy as compared with standard
care group.

Conclusion:
There was a statistically significant reduction in GWG in overweight and obese pregnant
women. Owing to the promising results shown by exercise intervention and PA in maternal
weight control, these interventions should be used as a tool for managing weight gain during pregnancy
as routine care.

Authors: Bittencourt Mauricio Vaz Lobo , Correa Natássia Zanotto 
Published: March 2021

Diante da adoção de um sistema de taxas de câmbio flutuante, após a quedado sistema monetário Bretton Woods, vários países passaram a experimentar o aumento da variabilidade da taxa de câmbio, com diversas consequências para as suas economias. O objetivo central deste estudo consiste em analisar o efeito da volatilidade dataxa de câmbio sobre o comércio brasileiro a nível setorial, dito diferentemente, sobre acomposição da pauta de exportação brasileira. Para tanto, considera-se o volume exportado do Brasil para seus principais parceiros comerciais no período de 2001 a 2017, e, posteriormente, realiza-se uma classificação dos produtos em três categorias (básicos, semimanufaturados e manufaturados). A par¬tir de tal agrupamento, a composição da pauta de exportação é definida pela participação de cada categoria de produto no total do volume exportado para os respectivos parceiros. Adicionalmente, essa variável éutilizada como dependente em um modelo gravitacional de comércio, o qual é estimado usando-se os métodos de mínimos quadrados ordinários agrupado, econometriade painel e Poisson pseudo maximum likelihood. Os resultados obtidos indicam que avolatilidade cambial tem um efeito adverso apenas sobre o setor de manufaturas, comefeito positivo nas exportações de produtos básicos e nenhum efeito significativo sobreo comércio de produtos semimanufaturados.
Energy selection functions: modelling the energetic drivers of animal movement and habitat use
Authors: Klappstein Natasha J. , Potts Jonathan , Michelot Théo , Börger Luca , Pilfold Nicholas , Lewis Mark , Derocher Andrew 
Published: March 2021

1. Energetics are a key driver of animal decision-making, as survival
depends on the balance between foraging benefits and movement costs.
This fundamental perspective is often missing from habitat selection
studies, which mainly describe correlations between space use and
environmental features, rather than the mechanisms behind these
correlations. To address this gap, we present a new modelling framework,
the energy selection function (ESF), to assess how moving animals choose
habitat based on energetic considerations.
2. The ESF considers that the likelihood of an animal selecting a
movement step depends directly on the corresponding energetic gains and
costs. The parameters of the ESF measure selection for energetic gains
and against energetic costs; when estimated jointly, these provide
inferences about foraging and movement strategies. The ESF can be
implemented easily with standard conditional logistic regression
software, allowing for fast inference. We outline a workflow, from
data-gathering to statistical analysis, and use a case study of polar
bears (Ursus maritimus) as an illustrative example.
3. We show how defining gains and costs at the scale of the movement
step allows us to include detailed information about resource
distribution, landscape resistance, and movement patterns. We
demonstrate this in the polar bear case study, in which the results show
how cost-minimization may arise in species that inhabit environments
with an unpredictable distribution of energetic gains.
4. The ESF combines the energetic consequences of both movement and
resource selection, thus incorporating a key aspect of evolutionary
behaviour into habitat selection analysis. Because of its close links to
existing habitat selection models, the ESF is widely applicable to any
study system where energetic gains and costs can be derived, and has
immense potential for methodological extensions.

Authors: Corral Pablo , Lopez Abel Alberto Pavia , Giunta Gustavo , Buitrago Andres Felipe , Saraiva Jose Francisco Kerr 
Published: March 2021

Background and Aims: As a result of the current demographics,
increased projections of atherosclerotic cardiovascular disease (ASCVD)
and prevalence of the disease in Latin America (LA), a panel of
multidisciplinary experts developed a review of ASCVD in this Region
considering the available and appropriate diagnostic methods,
classifying the disease and initiating appropriate treatment. The panel
expects to increase the awareness of this prevalent disease, decrease
consequences of ASCVD with corresponding cost savings and, ultimately,
decrease the overall burden of ASCVD in LA. Methods: A selected
panel of Latin American experts in fields related to ASCVD were provided
with a series of relevant questions to address prior to the multi-day
conference. Within this conference, each narrative was discussed and
edited by the entire group, through numerous drafts and rounds of
discussion until a consensus was achieved. Results: The authors
propose specific and realistic recommendations for increasing the
awareness of ASCVD in LA and in other countries in a similar situation.
Moreover, in creating these recommendations, the authors strived to
address all barriers and impediments mentioned previously within this
review. Conclusion: This manuscript provides a review of the
current state of ASCVD in LA. Additionally, the panel proposes practical
recommendations that should be implemented throughout the Region in
order to decrease the burden of ASCVD and effectively preventing the
consequences in future generations. These recommendations can serve as a
framework for LA and other countries in similar situations.

In Defense of Limited Manufacturing Cost Control: Disciplining Acquisition of Private Information by Suppliers
Authors: Arya Anil , Mittendorf Brian , Ramanan Ram N. V. 
Published: March 2021

ABSTRACT
When a firm's input supplier can acquire and misreport private information to gain an edge in negotiations, we show that the firm can blunt the supplier's informational advantage by permitting inefficiencies in its own internal production. Specifically, we establish that a modest increase in the cost of the input(s) a firm makes internally credibly commits it to be more aggressive in negotiations with a supplier for the input(s) the firm buys. Recognizing that its potential information rents will be limited, the supplier, in turn, becomes less aggressive in information acquisition. The paper fully characterizes the equilibrium—the firm's investments, the supplier's information acquisition and reporting decisions, and the terms of trade—to demonstrate that often-maligned internal bloat can be an endogenous facilitator of efficient outsourcing.
The Effect of Staff Auditor Reputation on Audit Quality Enhancing Actions
Authors: Blum Emily S. , Hatfield Richard C. , Houston Richard W. 
Published: March 2021

ABSTRACT
Auditors often face situations in which acting on their professional obligations comes with potential personal costs. Drawing upon the Theory of Reputation in Organizations, we predict that perceived costs associated with these actions are lower for auditors with positive reputations, which, in turn, influences their actions. In our first experiment, participants perceive that auditors with negative reputations face a more constrained choice set when anticipating a budget overage. Further, participants perceive that those with positive reputations are more likely to proactively report the overage and less likely to underreport hours worked, a result mediated by the anticipated impact on evaluations for “speaking up.” In a second experiment, we manipulate reputation in a live simulation and demonstrate a causal link between reputation and auditors' skeptical action. Taken together, our experiments provide evidence that an auditor's perceived reputation influences their choice to engage in audit quality enhancing behaviors.
The Revolving Door between Large Audit Firms and the PCAOB: Implications for Future Inspection Reports and Audit Quality
Authors: Hendricks Bradley E. , Landsman Wayne R. , Peña-Romera F. Dimas 
Published: March 2021

ABSTRACT
This study examines whether audit firms hire former PCAOB employees in response to negative PCAOB inspection reports, and whether such hiring leads to reductions in future inspection deficiencies and an increase in audit quality. We find that the number of PCAOB employees hired by large audit firms is positively related to the number of deficiencies reported in their prior inspection reports, and that the number of deficiencies reported in firms' future inspection reports is negatively associated with the number of former PCAOB employees hired. However, we find no significant association between the number of former PCAOB employees that a firm hires and improvement in audit quality. These findings suggest that former PCAOB personnel possess valuable knowledge about how to perform and document audit procedures to satisfy PCAOB reviewers, but that this expertise does not necessarily have direct implications for the accuracy and reliability of clients' financial reports.

Correlates of Actual and Self-Reported Knowledge and Skills, Attitudes, and Barriers Mitigating Against the Implementation of Evidence-Based Practice in Physiotherapy
Authors: Balogun Joseph , Mbada Chidozie E. , Oyeyemi Adetoyeje Y. , Awoleye Faith A. , Olakorede David B. , Balogun Adetutu 
Published: March 2021

Background: Evidence-based practice (EBP) has in the last decade gained global prominence in healthcare professions including physiotherapy. Several studies have been conducted worldwide to determine physiotherapists' knowledge, attitudes, beliefs, behaviors, skills, and resources, and barriers mitigating against the implementation of EBP in physical therapy, but there is limited information on the correlation among actual (competence) and self-report (perceived) knowledge and skills about EBP.
Methods: This cross-sectional study investigated the premise of these associations among 233 Nigerian physiotherapists who completed a previously validated 55-item questionnaire that assessed demographic data, actual and self-report knowledge, skills and resources, attitudes, and barriers about EBP.
Result: We found no significant relationship between actual knowledge of EBP and clinical experience (r=.086, p>.05), age (r=.048, p>.05), academic degree (r=.108, p >.05), self-reported knowledge (r=.097, p>.05), and self-reported skills about EBP (r=.095, p>.05). Demographic variables (age, years of clinical experience, and academic degrees) and psychosocial factors (self-reported knowledge, skills and resources, attitudes, and barriers about EBP) are not a significant predictor of actual knowledge of EBP.
Conclusion: The physiotherapists perceived that they are competent about EBP but in reality, they are not, and may fail to seek educational resources that will improve their understanding and improve their skills about EBP.

Published: March 2021

Este trabajo presenta los avances de un estudio en curso centrado en la conversación política generada alrededor de discursos paródicos de coyuntura publicados en distintas plataformas de redes sociales. La hipótesis de base de dicho estudio sostiene que el dispositivo sociotécnico de las interfaces y las características del lenguaje audiovisual condicionan los modos en los que la conversación política contemporánea ocurre en estos sitios, y ejercen influencia en las formas en las que la expresión política se dinamiza en la actualidad.
El artículo aborda los videos paródicos virales del prosumer Matías Mazzagatti. Estos textos retoman productos de animación japonesa y hechos y actores de la coyuntura política argentina. La metodología seguida es el análisis comparativo entre YouTube, Facebook y Twitter observando las operaciones de sentido tanto en producción como en recepción. En producción se observaron las operaciones en relación al uso del lenguaje audiovisual y en recepción las operaciones en relación a los comentarios de los/as usuarios/as. Se evalúa la circulación de los textos seleccionados teniendo en cuenta la injerencia del dispositivo en la conversación política paródica. Concluimos que se pueden observar diferencias sociotécnicas entre las plataformas que habilitan distintas modalidades de conversación política en las redes sociales.

Published: March 2021

Abstract
At present, the economic benefits of double inlet and double outlet ball mills, which are commonly used in coal-fired power plants, need to be improved. Based on this, this paper explores the factors influencing the output of double inlet and double outlet ball mill by establishing the output system of double inlet and double outlet ball mill. By analyzing the influence factors of the output of double inlet and double outlet ball mill, and combining with system dynamics, the dynamic model of double inlet and double outlet ball mill output system is established, and SPSS is used to fit the model data with the real data. The fitting degree is above 0.8, and the authenticity is high. The simulation results show that the impact energy of barrel grinding, the grinding powder fineness, and the pressure ratio in the ball mill affect the output of double inlet and double outlet ball mill according to certain relations. Finally, the research in this paper provides theoretical and technical support for improving the economic benefits of double inlet and double outlet ball mills.
Translation as a Catalyst in the Development of Modern Chinese Legal Language
Authors: Cao Deborah 
Published: March 2021

AbstractThis paper focuses on the translation of legal language and the development of modern Chinese legal language as a translated legal language. It first describes the historical contexts in which China underwent enormous and unprecedented social and political changes including changes to law in the late 1800s and early 1900s. It then discusses how translation played an important catalyst role in introducing Western law, legal practices, legal concepts and terminology in the emerging modern Chinese legal language as we know it today, and in the process, lent a helping hand in negotiating China’s transition to modernity through translation and creating a new legal language and legal system. It also considers the issues in translingual and cross-cultural communication and understanding translated Chinese legal language.
Measurement of the dimensions of personality traits in patients addicted to psychoactive substances in context of relapses
Authors: Chmielowiec Krzysztof , Boroń Agnieszka 
Published: March 2021

Abstract

Introduction: Recurrent use of psychoactive substances, including alcohol, affects most patients. It is an expression of the chronicity of the disease process. Understanding the causes of this phenomenon is the key to searching for effective therapeutic strategies for this disease.

The aim: Analysis of individual dimensions of personality traits in patients in the context of relapses.

Material and method: The research was carried out on a group of 301 people addicted to psychoactive substances staying in an addiction therapy center in Lubuskie and Zachodniopomorskie voivodships in Poland. The subjects were divided into two groups. The first group consisted of addicts with reported one-time therapy. The second group consisted of addicts who received at least two treatments at an addiction therapy center. The personality dimension was measured using the NEO-FFI questionnaire and the STAI questionnaire.

Results: The following percentages of neuroticism (NF NEUR) were marked in people addicted to psychoactive substances with a single stay in an inpatient treatment center: 8.55% with low intensity, 40.13% with moderate intensity and 51.32% with high intensity. On the other hand, in people addicted to psychoactive substances with multiple stays in an inpatient treatment center, the features of low-grade neuroticism were found to be 6.85%, 25.34% of moderate and 67.81% of high intensity (χ2 = 8.643, p = 0.013).

Conclusions: A higher score on the Nervousness Scale of the Neo FFI inventory has a significant impact on the course of addiction and the occurrence of relapses.

Authors: Goli Alireza , Tirkolaee Erfan Babaee , Weber Gerhard-Wilhelm 
Published: March 2021

Abstract
This paper addresses Acoustic Emission (AE) from Computer Numerical Control (CNC) machining operations. Experimental measurements are performed on the CNC lathe sensors to provide the power consumption data. To this end, a hybrid methodology based on the integration of an Artificial Neural Network (ANN) and a Shuffled Frog-Leaping Algorithm (SFLA) is applied to the data resulting from these measurements for data fusion from the sensors which is called SFLA-ANN. The initial weights of ANN are selected using SFLA. The goal is to assess the potency of the signal periodic component among these sensors. The efficiency of the proposed SFLA-ANN method is analyzed compared to hybrid methodologies of Simulated Annealing (SA) algorithm and ANN (SA-ANN) and Genetic Algorithm (GA) and ANN (GA-ANN).
