The Use of Web-Based Portfolio as Alternatife Assesment in Biology Learning
No full textThe current state of the Covid-19 pandemic has had an impact on various ongoing activities, including learning activities. Currently, the government provides a policy to organize learning from home, known as Learning From Home (BDR). Learning From Home in its implementation requires the support of mobile devices. It is a challenge for both teachers and students to master technology in learning in these conditions. In addition, teachers must also be able to carry out the teaching and learning process or provide assessments/evaluations to students face-to-face (done online). The research objective is to determine the use of alternative assessment-based portfolios in biology learning. The authors want to introduce web-based portfolios as alternative assessments in biology learning in this study. Alternative assessments can support students to understand biology lessons with the task of making lab reports, making herbariums, drawing, writing widespread scientific reports, etc. These are collected in the form of website links. The research method used is a literature study that the author has carried out. The results obtained are using a web-based portfolio as an alternative assessment in biology learning, which is still not widely applied even though this assessment is very efficient to apply in biology learning during the Covid-19 pandemic. This research concludes that every lesson that has been carried out certainly needs to be assessed on student learning outcomes in following each lesson that has been followed. In this case, an alternative web-based portfolio assessment is one of the solutions to evaluate the performance and work of students so that all activities carried out can be rewarded with value.                Keywords: Biology Alternative Assessment, Web Based Portofolio Â

The Phenomenon of Vaping in Female Students
Get PDFIn its development, vaping is not only in demand by men, but women have also become its users. Some societies still stigmatize women who smoke or vape. Women who vape or smoke are often referred to as unrighteous or naughty women and get ridiculed or cursed. In fact, vaping behavior in women is inseparable from the motives that are their reasons for vaping. The purpose of this study is to find out what the motives of women for vaping are, what effects are obtained after using vaping, and what stigma is obtained. The research was conducted using a qualitative approach with primary and secondary data collection techniques. Primary data collection was conducted through an in-depth interview method (a departmental interview) by finding three key informants. The informant requirement is a woman who is a vape perpetrator. secondary data in this study using a review of online literature. The database used is in the form of Google Scholar, where the author combines words relevant to themes such as "Vape and Women," "Motif," and "Stigma." The results of the study concluded that one of the reasons women vape is to think that vaping is something cool. Faster fatigue and shortness of breath are two of the effects they receive after vaping. Women who vape also often receive negative ratings from the surrounding community; they are often said to be bad women

Final states with three leptons, electrons or muons, and at least one jet are investigated. A moderate excess of events compatible with SM tZq production is observed, and the corresponding cross section is measured to be with a significance of . No presence of FCNC production of tZ(q) is observed and exclusion limits at confidence level on the branching ratios of a top quark decaying to a Z boson and an up or a charm quark are found to be and , respectively. \textit{This document has been revised with respect to the version dated August 4, 2016.}$

Study of vector boson scattering and search for new physics in events with two same-sign leptons and two jets
Get PDFThis article is available under the terms of the Creative Commons Attribution 3.0 License. Further distribution of this work must maintain attribution to the author(s) and the published article’s title, journal citation, and DOI.A study of vector boson scattering in pp collisions at a center-of-mass energy of 8 TeV is presented. The data sample corresponds to an integrated luminosity of 19.4fb-1 collected with the CMS detector. Candidate events are selected with exactly two leptons of the same charge, two jets with large rapidity separation and high dijet mass, and moderate missing transverse energy. The signal region is expected to be dominated by electroweak same-sign W-boson pair production. The observation agrees with the standard model prediction. The observed significance is 2.0 standard deviations, where a significance of 3.1 standard deviations is expected based on the standard model. Cross section measurements for W±W± and WZ processes in the fiducial region are reported. Bounds on the structure of quartic vector-boson interactions are given in the framework of dimension-eight effective field theory operators, as well as limits on the production of doubly charged Higgs bosons
Search for jet extinction in the inclusive jet-pT spectrum from proton-proton collisions at s=8 TeV
Get PDFPublished by the American Physical Society under the terms of the Creative Commons Attribution 3.0 License. Further distribution of this work must maintain attribution to the author(s) and the published articles title, journal citation, and DOI.The first search at the LHC for the extinction of QCD jet production is presented, using data collected with the CMS detector corresponding to an integrated luminosity of 10.7 fb−1 of proton-proton collisions at a center-of-mass energy of 8 TeV. The extinction model studied in this analysis is motivated by the search for signatures of strong gravity at the TeV scale (terascale gravity) and assumes the existence of string couplings in the strong-coupling limit. In this limit, the string model predicts the suppression of all high-transverse-momentum standard model processes, including jet production, beyond a certain energy scale. To test this prediction, the measured transverse-momentum spectrum is compared to the theoretical prediction of the standard model. No significant deficit of events is found at high transverse momentum. A 95% confidence level lower limit of 3.3 TeV is set on the extinction mass scale
Search for anomalous production of events with three or more leptons in pp collisions at √s = 8TeV

Further distribution of this work must maintain attribution to the author(s) and the published articles title, journal citation, and DOI.A search for physics beyond the standard model in events with at least three leptons is presented. The data sample, corresponding to an integrated luminosity of 19.5fb-1 of proton-proton collisions with center-of-mass energy s=8TeV, was collected by the CMS experiment at the LHC during 2012. The data are divided into exclusive categories based on the number of leptons and their flavor, the presence or absence of an opposite-sign, same-flavor lepton pair (OSSF), the invariant mass of the OSSF pair, the presence or absence of a tagged bottom-quark jet, the number of identified hadronically decaying τ leptons, and the magnitude of the missing transverse energy and of the scalar sum of jet transverse momenta. The numbers of observed events are found to be consistent with the expected numbers from standard model processes, and limits are placed on new-physics scenarios that yield multilepton final states. In particular, scenarios that predict Higgs boson production in the context of supersymmetric decay chains are examined. We also place a 95% confidence level upper limit of 1.3% on the branching fraction for the decay of a top quark to a charm quark and a Higgs boson (t→cH), which translates to a bound on the left- and right-handed top-charm flavor-violating Higgs Yukawa couplings, λtcH and λctH, respectively, of |λtcH|2+|λctH|2<0.21
