Can weight predict academic performance in college students? An analysis of college women's self efficacy, absenteeism, and depressive symptoms as mediators
Venue: Journal of American college health J of ACH
Year: 2017

Over a third of American college students are either overweight or obese, which has been suggested to negatively impact their academic achievement.  This study seeks to better understand the relationship between body mass index (BMI) and grade point average (GPA) while examining potential mediators of this association.  The sample consists of 298 college women who volunteered to complete online questionnaires between October and December 2014.  Although no significant differences were noted for sociodemographic variables, overweight and obese female students were found to report lower GPA and academic self efficacy as well as higher depressive symptoms, compared with their normal weight counterparts. Academic self efficacy partially mediated the relationship between BMI and GPA.  To foster better academic achievement in female college students, and especially for those who are overweight and obese, strategies for improving self efficacy and adaptation to college should be implemented.
Modern Code Review: A Case Study at Google
Venue: 2018 IEEE/ACM 40th International Conference on Software Engineering: Software Engineering in Practice Track (ICSE SEIP)
Year: 2017

Employing lightweight, tool based code review of code changes (aka modern code review) has become the norm for a wide variety of open source and industrial systems. In this paper, we make an exploratory investigation of modern code review at Google. Google introduced code review early on and evolved it over the years; our study sheds light on why Google introduced this practice and analyzes its current status, after the process has been refined through decades of code changes and millions of code reviews. By means of 12 interviews, a survey with 44 respondents, and the analysis of review logs for 9 million reviewed changes, we investigate motivations behind code review at Google, current practices, and developers' satisfaction and challenges.
STRENGTHS AND LIMITATIONS OF QUALITATIVE AND QUANTITATIVE RESEARCH METHODS
Year: 2017

Scientific research adopts qualitative and quantitative methodologies in the modeling and analysis of numerous phenomena. The qualitative methodology intends to understand a complex reality and the meaning of actions in a given context. On the other hand, the quantitative methodology seeks to obtain accurate and reliable measurements that allow a statistical analysis. Both methodologies offer a set of methods, potentialities and limitations that must be explored and known by researchers. This paper concisely maps a total of seven qualitative methods and five quantitative methods. A comparative analysis of the most relevant and adopted methods is done to understand the main strengths and limitations of them. Additionally, the work developed intends to be a fundamental reference for the accomplishment of a research study, in which the researcher intends to adopt a qualitative or quantitative methodology. Through the analysis of the advantages and disadvantages of each method, it becomes possible to formulate a more accurate, informed and complete choice.
Environmental Education in Morocco
Year: 2020

This book investigates the representation of Environmental Education (EE) in Moroccan textbooks using an Ecolinguistic and semiotic analysis. To this end, three textbooks have randomly been selected from the list of available official textbooks. A content analysis was adopted to examine how EE is represented both linguistically and semantically. The occurrence of certain linguistic features, namely nominalization, verbs, and passive voice which indicate willingness to hide the real agent behind the action. The study has also revealed that the content of the three selected textbooks is rich in terms of environmental aspects with few local environmental references. In addition to content analysis, a semiotic analysis, chiefly Barthes' framework (1972) was used in order to analyze three introductory images. All in all, this book is an endeavor to measure the effectiveness of English textbooks with a pure emphasis on environment using a mixed method approach. This study suggests important pedagogical implications on curriculum designers, textbook writers and English teachers, for the finding are hoped to draw attention to vital aspect which has been neglected in curriculum design.
A simulation based scheduling system for real time optimization and decision making support
Year: 2011

This paper presents an industrial application of simulation based optimization (SBO) in the scheduling and real time rescheduling of a complex machining line in an automotive manufacturer in Sweden. Apart from generating schedules that are robust and adaptive, the scheduler must be able to carry out rescheduling in real time in order to cope with the system uncertainty effectively. A real time scheduling system is therefore needed to support not only the work of the production planner but also the operators on the shop floor by re generating feasible schedules when required. This paper describes such a real time scheduling system, which is in essence a SBO system integrated with the shop floor database system. The scheduling system, called OPTIMISE scheduling system (OSS) uses real time data from the production line and sends back expert suggestions directly to the operators through Personal Digital Assistants (PDAs) The user interface helps in generating new schedules and enables the users to easily monitor the production progress through visualization of production status and allows them to forecast and display target performance measures. Initial results from this industrial application have shown that such a novel scheduling system can help both in improving the line throughput efficiently and simultaneously supporting real time decision making.
Joint effect of mid and late life blood pressure on the brain
Venue: Neurology
Year: 2014

We hypothesized that in participants with a history of hypertension, lower late life blood pressure (BP) will be associated with more brain pathology.  Participants are 4,057 older men and women without dementia with midlife (mean age 50 6 years) and late life (mean age 76 5 years) vascular screening, cognitive function, and brain structures on MRI ascertained as part of the Age, Gene/Environment Susceptibility (AGES) Reykjavik Study.  The association of late life BP to brain measures depended on midlife hypertension history. Higher late life systolic and diastolic BP (DBP) was associated with an increased risk of white matter lesions and cerebral microbleeds, and this was most pronounced in participants without a history of midlife hypertension. In contrast, in participants with a history of midlife hypertension, lower late life DBP was associated with smaller total brain and gray matter volumes. This finding was reflected back in cognitive performance; in participants with midlife hypertension, lower DBP was associated with lower memory scores.  In this large population based cohort, late life BP differentially affects brain pathology and cognitive performance, depending on the history of midlife hypertension. Our study suggests history of hypertension is critical to understand how late life BP affects brain structure and function.

Evaluation of Blockchain Algorithm for Smart Rental Application using Smart Contract
Venue: 2021 International Conference on Computer Information Sciences (ICCOINS)
Year: 2021

Blockchain technology has emerge over the years since the introduction of Bitcoin and Ethereum cryptocurrency, to the point the value of these cryptocurrencies are as high as a bar of gold. Since Ethereum has been an open source development platform, the industry has taken advantage of decentralized application or DApp where by the application is based on Smart Contract, a set of programming written code becomes the law of in agreement. Hence, the same can implement in House Rental industry where all contract agreement between tenant and landlord were conducted using pen and paper method. Even though, there are applications for this segment in the industry but most of the applications were not able keep data tracking and secure information. In this paper, a comparison is made to propose which algorithm is best to be used in the blockchain application and a better understanding how blockchain works.
Effect of an electric field during the deposition of silicon dioxide thin films by plasma enhanced atomic layer deposition: an experimental and computational study.
Venue: Nanoscale
Year: 2020

The growth, chemical, structural, mechanical, and optical properties of oxide thin films deposited by plasma enhanced atomic layer deposition (PEALD) are strongly influenced by the average bias voltage applied during the reaction step of surface functional groups with oxygen plasma species. Here, this effect is investigated thoroughly for SiO2 deposited in two different PEALD tools at average bias voltages up to 300 V. Already at a very low average bias voltage 10 V) the SiO2 films have significantly lower water content than films grown without biasing together with the formation of denser films having a higher refractive index and nearly stoichiometric composition. Substrate biasing during PEALD also enables control of mechanical stress. The experimental findings are supported by density functional theory and atomistic simulations. They demonstrate that the application of an electric field during the plasma step results in an increased energy transfer between energetic ions and the surface, directly influencing relevant surface reactions. Applying an electric field during the PEALD process leads to SiO2 thin films with significantly improved properties comparable to films grown by ion beam sputtering.
Leonid TARUASHVILI TECTONICS OF DIVINE BODY IN THE ILIAD AND ITS EARLY MODERN TRANSLATIONS: DREAM AND ATHENA PREFACE
Year: 2014

When I was about to write a study on how the plastic images of Homer's epics were perceived and rendered in early modern time, I had a mind to concentrate first and foremost on book illustration. What is quite understandable, since pictorial interpretation more than any other one must have to do or so it seems at least with the plastic values of verbal interpretandum. Furthermore, the material of Homer illustration in itself (it's sufficient to recall the famous engravings after John Flaxman, decorating numerous editions of the Iliad and Odyssey) is rich and appealing enough to constitute a subject of special study. However on mature reflection I have rejected the first idea and chosen the translations of Homer's epics as a material of paramount importance for the conceived study. The point is that exactly such translations constitute primary stage of image interpretation, for if not exclusively, then at least mainly from them illustrators drew stuff and inspiration for their figurative versions of Homeric poems; those translations and not original epics were for illustrators the real interpretandum. So the adequate analysis of illustrations to Homer cannot manage without taking into account the character and structure of visual images contained in translations, as well as without meticulous collation of these images with their correspondences in Homer text. But the both require a separate study. I don't dare to affirm that visual side of Homeric figurativeness were disregarded by researchers. However, I am inclined to think that their attention to such a matter was to a certain degree one sided, being concentrated chiefly on optical effects. In a general way, it was spoken sometimes of plastics, whereas the basis of Homer's plastic figurativeness, his classical (or positive as I shall call it here) tectonics, moreover in the aspect of its reflection in translations, became the subject of analytical treatment extremely seldom. Now let us determine more precisely the subject matter of the prospective study. This subject matter has two sides material and theoretical. What concerns the first, all is intelligible without any special elucidations; nevertheless I should repeat that concrete historical stuff of the study is texts of early modern translations of Homer's poems. However, in this texts we shall examine not everything that they contain, but only one certain facet. In its turn, this facet possesses two sides, one of which is the outer, looking at us, readers and representing the verbal significant, or else the plan of wordy expression of text. As to the other side, it is turned inside, to figurative contents of text and constitutes its plastic tectonic significate, or else the plan of content. Just that very double sidedness determines methodological double sidedness (or interdisciplinarity) of this study, which in its operating with verbal significants acts as philological, whereas in its turning to the plastic tectonic content, as art critical one.
Trying to Understand the Ppps in Icp2011: Why are the Results so Different?
Year: 2014

Purchasing power parity exchange rates, or PPPs, are price indexes that summarize prices in each country relative to a numeraire country, typically the United States. These numbers are used to compare living standards across countries, by academics in studies of economic growth, particularly through the Penn World Table, by the World Bank to construct measures of global poverty, by the European Union to redistribute resources, and by the international development community to draw attention to discrepancies between rich and poor countries. The International Comparison Program (ICP) collects the detailed prices on which these indexes are based on an irregular basis. In 2014, the ICP published PPPs from the 2011 round that are sharply different from those that were expected from extrapolation of the previous round, ICP 2005. These discrepancies will eventually have important implications for the Penn World Table, and for international comparisons of living standards given that the PPPs are used to convert countries' national accounts GDP and consumption, for example from local currency to common currency units (international dollars. The world according to ICP 2011 looks markedly more equal than the world according to ICP 2005. This paper investigates why this happened. We identify a likely source of the problem in the way that the regions of the ICP were linked in 2005. We use two different methods for measuring the size of the effect. Both suggest that the 2005 PPPs for consumption for countries in Asia (excluding Japan) Western Asia, and Africa were overstated relative to the United States by between 18 to 26 percent. Per capita consumption in international dollars of these countries was therefore too low in 2005 and more likely to be accurately estimated in 2011.
A Special Section of Intelligent Automation and Soft computing Soft Computing For Copyright Protection
Venue: Intell. Autom. Soft Comput.
Year: 2011

In today's digital age, the creation, transmission and manipulation of digital media content, such as images, audios and videos, are made simply through digital processing tools that are easily and widely available. As a consequence, piracy that copies, tampers and retransmits the media content is becoming increasingly easier and more popular now. This eventually concurs a great deal of loss to content producers or service providers. Thus, developing the copyright protection technologies that are able to detect, prevent and authenticate the media content's copyrights becomes extremely urgent. In the past decade, some means have been proposed and used for copyright protection, such as digital watermarking for ownership protection, multimedia authentication for tampering detection, digital fingerprinting for traitor tracing, perceptual hash for copy tracking and piracy search, etc. The aim of this special issue is to present a collection of high quality research papers that report the latest research advances in the area of soft computing based copyright protection techniques. In this special issue, we selected 7 papers, which can demonstrate advanced works in this field. All the papers submitted to the special issue were reviewed by at least three anonymous referees each and had two rounds of improvement. A detailed overview of the selected works is given below. The first two papers are related with Digital Rights Management (DRM) Among them, the first one, entitled " Game Theoretic Analyses and Simulations of Adoptions of Security Policies for DRM in Contents Sharing Scenario " Yang) analyzes the relationship between two DRM stakeholders, i.e. providers and sharers. The game theory is introduced to model the mutual influence of adoptions of trusted computing enabled security policies on benefits of the two stakeholders. Although it is still an open issue, the paper's work will bring some innovative information to DRM system designers or operators.
Inhibition of Female and Male Human Detrusor Smooth Muscle Contraction by the Rac Inhibitors EHT1864 and NSC23766
Venue: Frontiers in Pharmacology
Year: 2020

Lower urinary tract symptoms (LUTS) due to overactive bladder (OAB) are caused by spontaneous detrusor contractions. Medical treatment with muscarinic receptor antagonists or b3 adrenoceptor agonists aims to inhibit detrusor contractions, but overall results are unsatisfactory. Consequently, improved understanding of bladder smooth muscle contraction and identification of novel compounds for its inhibition are needed to develop alternative options. A role of the GTPase Rac1 for smooth muscle contraction has been reported from the prostate, but is unknown in the human detrusor. Here, we examined effects of the Rac inhibitors NSC23766, which may also antagonize muscarinic receptors, and EHT1864 on contraction of human detrusor tissues.  Female and male human detrusor tissues were obtained from radical cystectomy. Effects of NSC23766 (100 uM) and EHT1864 (100 uM) on detrusor contractions were studied in an organ bath.  Electric field stimulation induced frequency dependent contractions of detrusor tissues, which were inhibited by NSC23766 and EHT1864. Carbachol induced concentration dependent contractions. Concentration response curves for carbachol were shifted to the right by NSC23766, reflected by increased EC50 values, but unchanged Emax values. EHT1864 reduced carbachol induced contractions, resulting in reduced Emax values for carbachol. The thromboxane analog U46619 induced concentration dependent contractions, which remained unchanged by NSC23766, but were reduced by EHT1864.  In addition to neurogenic and cholinergic contractions, EHT1864 inhibits thromboxane A2 induced detrusor contractions. The latter may be promising, as the origin of spontaneous detrusor contractions in OAB is noncholinergic. In vivo, both compounds may improve OAB related LUTS.
Optimal Synthesis of Wideband Beamforming Weights for Monopulse Tracking Radar The Linear Array Case
Venue: 2019 IEEE International Symposium on Antennas and Propagation and USNC URSI Radio Science Meeting
Year: 2019

An innovative and effective strategy for the synthesis of fixed geometry linear arrays generating sum and difference patterns for monopulse radar applications operating at maximum bandwidth is presented. The problem is formulated to obtain a sum pattern and a difference pattern with maximum directivity and slope along the boresight, respectively, while both satisfying mask power constraints on the sidelobes. Moreover, the two beams share the same amplifiers to reduce the beamforming network complexity. An iterative convex programming strategy is used to find the common amplitude coefficients satisfying the requirements on the radiation patterns over the possible largest bandwidth. A numerical result is reported to validate the proposed method.
