IDENTIFIKASI MISKONSEPSI SISWA MENGGUNAKAN UJI ISOMORFIK: KASUS HUKUM NEWTON TENTANG GERAKAbstractStudents' misconceptions can lead to learning failure if they are not addressed. In this study, using Google Form, we identify students’ misconceptions using the isomorphic test method on Newton's Law of Motion, especially the principles of dynamics. This study is quantitative research conducted in three junior high schools in South Tangerang. There are 90 participants involved that was selected by purposive sampling method. The research instrument was an isomorphic test in form of multiple choice with nine questions with three indicators namely: analyzing the application of Newton’s I law in daily life; analyzing the correlation between force and mass and the acceleration of a moving object; and analyzing the application of Newton’s III Law in daily life. The results showed that the students were identified as having misconceptions in Newton’s Law concept using isomorphic tests, including misconceptions of inertia and misconceptions of Newton’s Third Law of Motion. One of the misconceptions is that students assume an object will maintain its initial position in motion by applying a new force in the opposite direction. The students' misconceptions found in this study can be used as a reference so that they can be overcome in the learning process.AbstrakMiskonsepsi dapat menyebabkan siswa sulit belajar jika tidak segera diatasi.

This research deals with the symbolic miracles of the Qur’an in term of symbolic meaning contained in the Qur’an, from letters, numbers, names of surah and juz according to Luqman Abdul Qahar Sumabrata in his book “Fenomenologi Alquran”. The research aims to know some symbols in the Qur’an and tries to reveals the philosophy and meaning for each of the symbols. Discovering the philosophy and meanings of the Qur’an’s symbols can help to expand the fields of Qur’anic sciences and to show more aspects of the miraculous of the Qur’an. This research uses the inductive-analytical method, a library method and personal interview and dialogue with Lukman’s students. Among the results of this research are; that each of the elements in the Qur’an has a philosophy and a specific meaning related to the universe and humans, letters are the key to understanding the Qur'an, while numbers are the linking form of every elements which have dual forms and broad meanings. The research also reveals that names of surah and the arrangement of juz are depictions of cosmic and human psyche.
On the pitfalls of conceptualizing excessive physical exercise as an addictive disorder: Commentary on Dinardi et al. (2021)
Authors: Brevers Damien , Maurage Pierre , Kohut Taylor , Perales José C. , Billieux Joël 
Published: March 2022

Abstract
This commentary challenges some of the proposals made in the opinion paper entitled “The expanded interactional model of exercise addiction” by Dinardi, Egorov, and Szabo (2021). We first question the usefulness of the (expanded) interactional model of exercise addiction to determine the psychological processes underlying distress and functional impairment in excessive physical exercise. We then consider the authors’ use of the Self-Determination Theory to model exercise addiction, which risks the misclassification of strenuous, but adaptive, patterns of physical exercise as exercise addiction. We finally address broader concerns regarding the idea that maladaptive exercising could be conceptualized as an addictive disorder.
"My Voice is who I am" - Vocal Improvisation Group Work with Healthy Community-Dwelling Older Adults
Authors: Riabzev Aviya , Dassa Ayelet , Bodner Ehud 
Published: March 2022

Background: Vocal improvisation is known as beneficial in promoting well-being, yet not much is known about using vocal improvisation with healthy older adults. While the emphasis in music therapy on studying interventions with clinical populations of older adults is important, the challenges and stressors facing healthy older adults require more investigation.
Methods: This qualitative study analyzed the experiences of 54 older adults, ranging between 60 and 93 years (M=71.07), who participated in 12 weekly vocal improvisation group meetings that incorporated various voice improvisation techniques. Data was gathered using qualitative semi-structured group interviews with 12 focus groups (pre- and post-intervention).
Results: A qualitative content analysis revealed that the vocal improvisations created the sense of an open space where participants could express and explore their own voices. The intervention has changed their attitudes regarding their own voices and led to meaningful personal experiences and new self-discoveries. The participants described experiencing a significant emotional process during the group work and reported experiencing self-exploration, and improvements in their self-beliefs, attitudes regarding their own voices, and their well-being.
Conclusions: Vocal improvisation group intervention was experienced as beneficial for the well-being of healthy community-dwelling older adults.
EFFECT OF DIGITAL NOISE REDUCTION AND DIRECTIONALITY ALGORITHMS IN HEARING AIDS ON TEMPORAL ENVELOPE DISTORTION AND SPEECH RECOGNITION
Authors: Chinnaraj Geetha , Shetty Hemanth , Palaniyappan Vinodhini 
Published: March 2022

BackgroundDigital signal processing algorithms tend to alter temporal cues in the speech signal and yet individuals with hearing impairment rely strongly on these cues for speech perception. Hence, there is a need to assess the effect of these algorithms on temporal cues and speech perception. The present study aimed to quantify, in a wide dynamic range compression hearing aid, the individual and combined effects of digital noise reduction and directionality algorithms on temporal cues, syllable recognition, and sentence recognition. Temporal cues were quantified by the envelope difference index (EDI).Material and methodsThe study included 20 individuals (in the age range of 21 to 44 years) with mild to moderate sensorineural hearing loss. Sentence recognition, syllable recognition, and EDI were obtained at different levels in four different aided conditions – digital noise reduction algorithm only, directionality only, both digital noise reduction and directionality on, and both algorithms off. Sentences were presented in noise at +5 dB signal-to-noise ratio from 180° azimuth.ResultsCompared to independent activation of the algorithms, the combined algorithms significantly improved speech recognition scores at all presentation levels. The temporal changes induced by the algorithms were only mild, even though EDI was the highest when all the algorithms and the directional microphone were activated.ConclusionsThe noise reduction algorithms and compression induce temporal changes; however speech recognition improved when the algorithms were activated, presumably due to countervailing psychophysical factors.
Assessing the Effectiveness of Generalized Likelihood Ratio Test Detector Schemes in Seismic Event Detection and the Avoidance of Nontarget Signals
Authors: Vieceli Rhiannon E. , Dodge Douglas A. 
Published: March 2022

ABSTRACT
Cross-correlation techniques have played a long-standing and pivotal role in seismic event monitoring. However, the performance of correlation-based detectors is challenged by nuisance seismicity, or nontarget signals. Such detections are a problem when the mission is to automatically map events to the correct source region. Using aftershocks of the 2014 Mw 6.0 South Napa, California, earthquake, we demonstrate the effectiveness of utilizing a dynamic correlation processor framework in a generalized likelihood ratio test (GLRT) detector configuration to minimize nontarget detections. A GLRT maximizes a detection statistic with respect to one or more unknown parameters. In this case, the detection statistic is a template signal match against the waveform in a window sliding over a data stream, and the unknown parameter is an index variable indicating group membership of the template event or events. Detected events are assigned to the event group that yields the largest detection statistic. Our results show that a GLRT detector will outperform a suite of independently operating correlation and subspace detectors in terms of having a lower nontarget detection rate at a given missed detection rate. We also show that a GLRT detector composed of a few high-rank subspace detectors has a slightly higher nontarget detection rate, but a significantly lower missed detection rate, than a GLRT detector composed of many low-rank subspace detectors. The high-rank GLRT configuration produced impressive results even with marginal data (single channel, single station, and very low time bandwidth product), which bodes well for the utility of building efficient aftershock classification systems and global monitoring systems at larger scales. However, future work is required to assess performance at the regional scale and to assess the performance of the system at detecting target events not used in the detector template creation.
Unilateral absence of fibularis tertius: A clinically and evolutionary salient variation
Authors: Verma Poonam , Abrol Girish 
Published: March 2022

: Fibularis tertius muscle has always cherished the distinction of being an entirely human structure and as such it has aided to separate man from the lower animals. The morphology of the fibularis tertius (FT) is extremely inconstant. In the present case we report a rare case of unilateral absence of FT in right foot of a formalin embalmed male cadaver.The absence of FT may mislead the doctors in performing graft and transplant operations. Hence radiological imaging techniques must be executed to approve the presence of the FT before planning any manoeuvre on foot. Thus, presence or absence of the FT may have a clinical and evolutionary significance that is emphasized in our case reports.
Samoregulacja działalności gospodarczej i zawodowej. Organizacje samoregulacyjne w prawie rosyjskim
Authors: Małecki Witold 
Published: March 2022

Samoregulacja działalności gospodarczej i zawodowej polega na tworzeniu i kontrolowaniu przestrzegania norm kształtujących sposób wykonywania danej działalności przez podmioty prowadzące tę działalność. W prawie rosyjskim samoregulacja realizowana jest przede wszystkim w ramach funkcjonowania organizacji samoregulacyjnych zrzeszających podmioty określonej działalności gospodarczej lub zawodowej. Organizacje samoregulacyjne funkcjonują jako organizacje o dobrowolnym członkostwie oraz organizacje o obowiązkowym członkostwie. W określonych dziedzinach działalności gospodarczej i zawodowej uzyskanie członkostwa w organizacji samoregulacyjnej, uwarunkowane spełnieniem pewnych przesłanek, stanowi prawny wymóg podjęcia danej działalności. Z tej przyczyny organizacje samoregulacyjne o obowiązkowym członkostwie należy uznać za korporacje prawa publicznego. Publicznoprawne znamię tych organizacji odznacza się charakterem transcendentnym, z uwagi na oddolny sposób ich tworzenia.

Published: March 2022

In recent times, the language of mediatized genres has attracted much scholarly attention all over the world. However, little is known about the rhetorical structure and linguistic realisation of television talk shows in Ghana. This study, therefore, examined the Introduction sections of Newsfile, a popular television talk show telecast on JoyNews, a Ghanaian television station, to determine its schematic structure and linguistic realisations. Data for the study comprised five Introduction sections of the Newsfile aired after the 2016 general elections. The data were transcribed and analyzed based on the English for Specific Purposes (ESP) approach to genre analysis. The findings revealed that the Introduction section of the talk show was characterized by ten moves (Greetings, Naming of Programme, The Seller, Naming the Host, Invitation of Viewers, Introduction of Subject, Signalling Commercial Break, Host’s Address, Introduction of Guests, and Introduction of Sponsors), with the Host’s Address and Introduction of Guests realized by steps. The study also revealed that while some of these moves were obligatory, others were optional. Additionally, it was revealed that there were recursions of some moves. Further analysis revealed the linguistic resources used in each of the moves. This study has implications for scholarship on talk shows especially in sub-Saharan Africa, genre studies, pedagogy, and further research.

Abstract
This paper recommends standardized names and equations for the two most common uses of Mechanical Specific Energy (MSE) concepts: "Total MSE" and "Downhole MSE". These names and their equations should be used uniformly in all applications, including electronic drilling recorder (EDR) pick lists, rig site surveillance, engineering surveillance, data analytics, research, and technical publications.
Mechanical Specific Energy, used as a metric for drilling efficiency, is a mathematical calculation of the energy used per volume of rock drilled. The Downhole MSE equation calculates the efficiency of the bit alone, while the Total MSE equation includes both the bit and drill string. Those who use MSE in surveillance or analytics know the negative effects created by the lack of standardization over the years; it is certainly not a new problem.
The lack of standardized nomenclature has resulted in the use of the same name for different equations, or different names are given two equations that are identical. This affects the ability of drill teams to engage vendors in redesign of performance limitations or to communicate new operational practices between teams or rigs. In addition, this standard corrects a mathematical error that is common in calculating the Total MSE.
The concen with the inconsistencies has increased as MSE has become a key element in many automated optimization schemes. Inconsistencies or uncertainties in the basis of MSE values calculated in real time or shared in large data sets will affect the industry's ablity to develop useful analytics or to automate rig control platforms and data-driven decisions.
This paper also includes a discussion of the MSE measurement errors and their effect on calculated values, which is of particular interest to controls engineers and those involved in data analytics. Examples are provided to illustrate how the two different MSE values are used in field operations. Also, a substantial reference list of current and potential future uses of MSE is included to encourage better MSE-based practices to potentially lead to the development of new uses in the future, including automation.
This ad hoc MSE Standardization Committee is a volunteer group with representation from operators, rig contractors, service companies, and data acquisition vendors. The guidance given reflects there shared experienec in utilizing MSE in surveillance and analytics, and the recommended equations are technically correct.

Published: March 2022

Abstract
In this study, mercaptosuccinic acid capped CdSe nanocrystals was successfully synthesized by in-situ medium colloid and used as photocatalyst for the effective photodegradation of methylene blue from aqueous solution under visible light and sunlight irradiations. The particle size and the crystal structure of these nanocrystals were analyzed by different analytical techniques. Dye adsorption prior to photocatalysis using these nanomaterials was studied via the experimental quantification of kinetics and isotherms. These experimental data were modeled including the application of statistical physics theory to analyze the corresponding adsorption mechanism. A maximum adsorption capacity of 27.1 mg/g (80% of dye removal) was observed in 10 min using an initial concentration of 30 mg/L. Statistical physics calculations indicated that the adsorption energy was lower than 40 kJ/mol. It was also established that the dye adsorption was associated to the electrostatic interactions and hydrogen bonding. Overall, the dye removal was a spontaneous, feasible and exothermic process. Adsorption properties of CdSe-MSA nanocrystals improved the dye photodegradation efficiency under visible light thus achieving up to 80% degradation in 60 min. The synergic effect of adsorption and photocatalytic degradation performance was mainly due to the surface area, small size (3.7 nm) and structural defects (selenium vacancies Se, interstitial of cadmium ICd) of nanocrystals, which enhanced the response of these nanomaterials inside the visible range for the photocatalytic activity. In summary, these nanocrystals are promising materials to be used in wastewater treatment under sunlight for the removal of organic compounds like dyes.

Authors: Li Bin , Lei Li , Zhang Kaidi , Wei Haiying , Li Aimei 
Published: March 2022

Abstract

Experiential advantage literature suggests that experiential purchase could make consumer happier and made a recommendation of experience than material purchase. However, most research has focused on the effect of these two types of purchases on their consequences, which ignore the antecedent factors that affect consumers’ consumption decision making. This study discusses when and why would consumers prefer to experiential purchase or material purchase. We test if message framing (such as promotion and prevention) would affect differential types of purchases’ consumption intention or not. In Study 1, participants in prevention condition perceived higher value of material purchase than experiential purchase, then caused they chose material purchase in preference to experiential purchase. In Study 2, participants in the promotion condition perceived higher value of experiential purchase than material purchase, then caused they chose experiential purchase in preference to material purchase. Results suggest that message framing would affect differential types of purchases’ consumption intention through their perceived value.

Published: March 2022

Abstract
Aging is accompanied with progressive deterioration of immune responses and tissues function. Using 12-month old mice as model, we showed that conditioned medium of human cord blood mesenchymal stem cells (CBMSC-CM) significantly reduced the population percentage of CD3-CD335 + NK and CD4 + CD25 + regulatory T cells in peripheral blood. The CBMSC-CM administration also increased naïve T cells number and restored the ratio of naïve to memory T cells in CD4 + T cells population. These results indicated that CBMSC-CM improved the immune response efficiency of aged mice. Moreover, we also found CBMSC-CM treatment significantly reduced the number of senescent cells in kidney tissues. Finally, we demonstrated that CBMSC-CM remarkably attenuated hydrogen peroxide triggered T cell response and ameliorated oxidative stress induced cellular senescence. All of these data suggest a prominent anti-aging effect of secretome of CBMSCs.
