Authors: Kuzmina I. Yu. , Ignatovich L. S.
Published: February 2021

On the basis of the "Komarova" farm (Magadan, Magadan region), the effect of introducing a new non-traditional component feed additive of plant origin into the diets of young cattle was studied. The research was carried out during the stall period. For the experiment there were taken four groups of animals (14-16 months of age) divided at random in accordance with the genotype into control and experimental groups of ten animals each. The first two groups (control, experiment) included purebred Holstein bulls, the other two – hybrids of the 1st generation (1/2 Holstein × 1/2 Herefords). For the experimental groups, the main diet was supplemented with a component feed additive consisting of cedar elfin (Mountain pine) flour and lichens (alpine cladonia (Cladonia alpestris), Icelandic cetraria (Cetraria islandica)). The results of the experiment has shown that the feed additive, consisting of 120 g of cedar elfin needle flour and 50 g of lichen flour (80% of Cladonia alpestris and 20% of Cetraria islandica), has a positive effect on the intensification of metabolic processes in the animals. The digestibility of crude protein increased by 1.29-4,19 g (1.7-5.6 %); that of the organic matter – by 6.65-8.90 g (11.0-14.3 %); NFE (nitrogen-free extracts) – by 7.80-9.18 g (14.14-15.70 %). An increase in the digestibility of feed nutrients had a positive effect on an increase in live weight gain by 0.60-3.0 g (1.35-5.93 %). An increase in feed conversion was 0.24-6.8 MJ (0.20-6.74 %); feed protein – by 0.02-0.09 g (1.22-6.17 %). Crossbred bulls turned out to be more responsive to changes in the ration of feeding and showed better results in all studied parameters. The effectiveness of using the additive is due to the fact that the raw material for the production is obtained from wild plants growing in nature in sufficiently large volumes. They do not require significant costs for harvesting and preparation for feeding.

PENGUKURAN PARTIKEL DI CLEANROOM TFME POLITEKNIK NEGERI BATAM MENGGUNAKAN STANDAR ISO 14644-1
Authors: Gautama Aditya , Budiana Budiana
Published: February 2021

Electronics Tecnology is currently developing very rapidly. Computational capabilities that continue to increase are accompanied by a decrease in the size of the electronic components used on a chip or IC (Integrated Circuit). The size of the components that have reached nanometers makes the components very sensitive to impurities in the form of particles. A special fabrication place in the form of a cleanroom is needed so that the number of impurity particles can be controlled and the damage caused by impurity particles on the product can be reduced. One of the standards used to classify a cleanroom and measure the particles in it is ISO 14644-1. In this study, particle measurements were carried out in accordance with ISO 14644-1 standards to measure the number of particles in the TFME cleanroom. The measurement results classify the cleanroom in TFME into ISO Class 7. This is consistent with the initial TFME cleanroom design, meaning that the particle filtration system is still in a good condition.

Authors: Bedekar Mangesh , Joshi Prachi
Published: February 2021

Cartoons, these days have become an integral part of every child’s childhood. They are amongst the most prominent forms of entertainment for children. With the advent of the nuclear family and single child families, with no mate/partner to interact, play or learn from, it is with the help of cartoons that kids are exposed to the various facets of the world around us. Cartoon films screened on most TV sets in Indian homes were majorly dubbed versions of successful cartoon films from USA, Japan, Canada, etc. From around 2003 onwards, some Indian cartoons started to appear on TV especially after the Cable TV came to Indian homes. This paper looks at the cartoons, which are made in India, made for India, and their co-relations with the cartoons which are otherwise screened on Indian TV sets, which are dubbed versions of cartoon films from around the world. These Indian cartoons are analysed and correlated with each other based on various attributes namely, the locale, the age of the protagonist, number of episodes, number of character in the movie, gender ratio, etc. The observations and conclusions done in this study are enlisted and presented.

Based on an online survey of 734 news podcast users in Korea, this study analyzed how motivations for podcast use and news podcast variables affected offline and online political participation. The results showed that any motivation did not have a significant effect on offline and online participation. Rather, discussions about issues transmitted through news podcasts were a positive predictor of online participation as well as offline participation. The discussion was also a mediator in the relationship between the time spent on a news podcast and offline/online political participation. That is, news podcast use enhanced political discussions, which promoted participation offline and online. Overall, these results indicate that discussions are important in the mobilization of political participation in the era of podcast.

Communication Vices that Engender Development: Oxymoronic Relevance of Social Media Use in Nigeria
Authors: Anyanwu Chukwuma , Ibagere Elo
Published: February 2021

The Nigerian journalist has lost his monopoly of information gathering, dissemination and control with the involvement of citizens in ‘journalism’ through social media especially Whatsapp. The objective of this paper is to show how through social media, with emphasis on Whatsapp, Nigerian citizens have been able to find their voices and can now contribute to societal well-being and development by embarking on information gathering and reporting. It uses participant-observation method to interrogate how citizen journalism has engendered development via negative journalism practice. The findings indicate that the government and other relevant stakeholders in the society respond to the voices of the people on issues which ordinarily would have been muted by conventional journalism practice or ignored by government. It concludes that citizen journalism through unconscious and unprofessional practice engenders development by somehow making government accountable through its response to issues of concern in areas that would otherwise, have been muted.

Reality Crime Programs in Turkish Television: The Notorious Case of Palu Family on Müge
Authors: Tetik Anlı Tuna , Özgüven Dilay
Published: February 2021

The crime drama has always been popular on radio and television. Following this popular programming type, these programs found its way into reality crime programs. The reality crime programs emerged in U.S television in the late 1980s as the combination of news, crime dramas, and even horror genre. The reality crime programs placed themselves mainly in two formats in the television world. There is a vignette format where actors reenact actual crimes, and another one is the live-action format. It is the 1990s for Turkey to introduce reality television to the audience. One of the popular programs that were first broadcasted on ATV in 2008 hosted by Müge Anlı is the Müge Anlı ile Tatlı Sert. After we discuss the popularity of the reality crime television and the cases from American television, MATS is discussed as a certain criminal case from Turkey. This case is publicly recognized as Palu Family. This article argues how the case of the Palu Family became a televised public psychosis in MATS which is a hybrid reality crime program. With this regard, we will study family violence, sexual abuse, and homicide that have become publicly available to the audience.

Authors: Wicaksono Setiawan
Published: February 2021

AbstractThis study aims to reformulate arrangements regarding expert judgment carried out by notaries through analysis of two regulations, namely, Law Number 30 of 1999 concerning Arbitration and Alternative Dispute Resolution (AAPS Act) and Law Number 2 of 2014 concerning Amendments to the Law Number 30 of 2004 concerning the Position of Notary (JN Act). In Article 1 point 10 of the AAPS Act, it is stated that expert judgment is one way of resolving disputes outside the court. The sound of this article provides an opportunity for notaries to provide expert judgment in the event of a dispute between the parties in an authentic deed, however, both the AAPS Act and the JN Act have not provided a complete regulation on this matter. Therefore, a more complete arrangement is needed so that notaries can play a bigger role in resolving disputes that arise. Expert assessment carried out by a notary will help the parties to understand the main problem at hand and help resolve the dispute. The research method used is normative juridical research, namely research that is focused on examining the application of the rules or norms in positive law. The findings of this study are a complete arrangement regarding the right of notaries to provide expert judgments, as well as the legality of such assessments.Keywords: deed; expertise; notaryAbstrak Penelitian ini bertujuan untuk merumuskan pengaturan mengenai penilaian ahli yang dilakukan oleh notaris melalui analisa dua peraturan yaitu, Undang-undang Nomor 30 Tahun 1999 tentang Arbitrase dan Alternatif Penyelesaian Sengketa (UU AAPS) dan Undang-undang Nomor 2 Tahun 2014 tentang Perubahan atas Undang-undang Nomor 30 Tahun 2004 tentang Jabatan Notaris (UU JN). Pada Pasal 1 angka 10 UU AAPS disebutkan penilaian ahli merupakan salah satu cara penyelesaian sengketa di luar pengadilan. Bunyi pasal ini memberikan peluang bagi notaris untuk memberikan penilaian ahli apabila terjadi sengketa antara para pihak dalam sebuah akta autentik, namun baik UU AAPS dan UU JN belum memberikan pengaturan yang lengkap mengenai hal ini. Oleh sebab itu, diperlukan pengaturan yang lebih lengkap sehingga notaris dapat berperan lebih besar dalam penyelesaian sengketa yang muncul. Penilaian ahli yang dilakukan oleh notaris akan membantu para pihak untuk memahami pokok permasalahan yang sedang dihadapi dan membantu terselesaikannya sengketa tersebut. Metode penelitian yang digunakan adalah penelitian yuridis normatif, yaitu dengan penelitian yang difokuskan untuk mengkaji penerapan kaidah-kaidah atau norma-norma dalam hukum positif. Penemuan dari penelitian ini adalah pengaturan yang lengkap mengenai hak notaris untuk memberikan penilaian ahli, serta kekuatan hukum penilaian tersebut.
Do Teacher Assistants Improve Student Outcomes? Evidence From School Funding Cutbacks in North Carolina
Authors: Hemelt Steven W. , Ladd Helen F. , Clifton Calen R.
Published: February 2021

This article examines the influence of teacher assistants and other personnel on outcomes for elementary school students during a period of recession-induced cutbacks in teacher assistants. Using panel data from North Carolina, we exploit the state’s unique system of financing its local public schools to identify the causal effects of teacher assistants, controlling for other staff, on measures of student achievement. We find consistent evidence of positive effects of teacher assistants, an understudied staffing category, on student performance in reading and math. We also find larger positive effects of teacher assistants on achievement outcomes for students of color and students in high-poverty schools than for White students and students in more affluent schools. We conclude that teacher assistants are a cost-effective means of raising student achievement, especially in reading.
Does Free Community College Improve Student Outcomes? Evidence From a Regression Discontinuity Design
Authors: Bell Elizabeth
Published: February 2021

In this article, I utilize a regression discontinuity design to estimate the effects of Tulsa Achieves—a prevalent and understudied type of tuition-free college program. In contrast to concerns regarding tuition-free community college suppressing bachelor’s degree attainment, I find that Tulsa Achieves increased the likelihood of transferring to 4-year colleges by 13 to 14 percentage points and increased bachelor’s degree attainment by approximately 2 percentage points. The estimates for shorter outcomes are underpowered to detect policy relevant effects, but suggest Tulsa Achieves increased college GPA and had a null impact on credit accumulation, retention, and graduation from Tulsa Community College.

Published: February 2021

The analysis and study of materials science and technological factors in the creation of film converters are carried out, the requirements for materials, their properties, and the technology of forming the converter elements are determined. It is shown that taking into account material science and technological factors ensures that the parameters of the film transducer match the required ones, resistance to external infiuencing factors, obtaining films of the initial composition, and stability of the production technology. The choice of material parameters is made taking into account the operating modes and conditions, static and dynamic loads acting on the elements of the converter, the properties of the starting materials and film elements. When joining dissimilar materials, the coefficients of linear expansion are taken into account. In the process of creating film converters, the initial materials, structural elements are processed in various technological environments and, are subjected to thermal effects, the specified structures and parameters of the film converter are formed, and at the same time, the imperfections in the initial materials and converter elements are amplified, which directly or indirectly affect the output parameters of the film converter. In the manufacture of film elements of the transducer, the choice of the method for producing thin films is determined by the purpose of the film, the compatibility of the method with other technological operations of microelectronic technology. The reproducibility of the electrophysical properties of thin films takes place during their deposition with a controlled composition, which is essential for the production of films based on semiconductor compounds and for the formation of the sensitive elements of the transducer. The analysis and study of methods for obtaining films showed that the energy efficiency of the process of ion sputtering of materials and the production of thin films of a given composition, technological fiexibility, the ability to control the thickness of the films by changing the current value, the deposition time and the pressure at which it is carried out are the most optimal.

Currently, a significant factor in assessing the quality and life of electrical products is repairability, that is, the ability to eliminate the failure of its operation when a defect is detected. The solution to this problem should be implemented based on a combination of factors of the technical system, for example, the structure of the organization, the availability of employees ' experience, its level, and so on. However, even here it is necessary to have mathematical models that can fully characterize the processes of finding elements with defects, since these models are able to identify recommendations that play an important role.

Airlines today use e-services extensively for marketing activities and the distribution of services. Monitoring and evaluating e-service quality are essential for customers’ satisfaction and thus the success of airlines. This study aims to evaluate e-service quality in the airline industry from the point of view of the consumers. To achieve this, an integrated Fuzzy Analytical Hierarchy Process (F-AHP) and Fuzzy Measurement Alternatives and Ranking according to Compromise Solution (F-MARCOS) approach was proposed to handle the uncertain and imprecise nature of e-service evaluation. In the first stage, e-service quality criteria were prioritized using the F-AHP method. Then, a real-world case study was carried out on scheduled airlines to demonstrate the applicability of the proposed approach using the F-MARCOS method, utilizing a total sample of 395 airline passengers in Turkey. As a result, the top three e-service criteria were found as reliability, understandability and security. A three-stage sensitivity analysis was also conducted to examine the credibility and stability of the results. This study is the first study to integrate F-AHP and F-MARCOS methods for the first time in literature.
CRK is differentially expressed in both lymph node and brain metastases in human breast cancer.
Authors: Mamoor Shahan
Published: February 2021

Metastasis to the brain is a clinical problem in patients with breast cancer (1-3). We mined published microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that the v-crk sarcoma virus CT10 oncogene homolog, encoded by CRK, was among the genes whose expression was most quantitatively different in the brain metastases of patients with metastatic breast cancer. CRK mRNA was present at decreased quantities in brain metastatic tissues as compared to primary tumors of the breast. Importantly, expression of CRK in primary tumors was significantly correlated with patient recurrence-free survival in patients with breast cancer. Modulation of CRK expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain.

Perceived Cultural Impacts of Climate Change Motivates Climate Action and Support for Climate Policy
Authors: Tam Kim-Pong , Leung Angela , Koh Brandon
Published: February 2021

The impacts of climate change on human cultures receive increasing attention in recent years. However, the extent to which people are aware of these impacts, whether such awareness motivates climate action, and what kinds of people show stronger awareness are rarely understood. The present investigation provides the very first set of answers to these questions. In two studies (with a student sample with N = 198 from Singapore and a demographically representative sample with N = 571 from the United States), we observed a generally high level of awareness among our participants. Most important, perceived cultural impacts of climate change robustly predicted intentions to engage in climate change mitigation behavior and climate activism, as well as support for climate policy. We also found expected associations between perceived cultural impacts and psychological and demographic variables (e.g., cosmopolitan orientation, moral inclusion, political orientation). These findings not only add a cultural dimension to the research on public understanding of climate change but also reveal a viable application of cultural frames as an effective climate communication strategy.
44 Tb/s fibreoptic data transmission from a single integrated chip source
Authors: Moss David
Published: February 2021

We report world record high data transmission over standard optical fiber from a single optical source. We achieve a line rate of 44.2 Terabits per second (Tb/s) employing only the C-band at 1550nm, resulting in a spectral efficiency of 10.4 bits/s/Hz. We use a new and powerful class of micro-comb called soliton crystals that exhibit robust operation and stable generation as well as a high intrinsic efficiency that, together with an extremely low spacing of 48.9 GHz enables a very high coherent data modulation format of 64 QAM. We achieve error free transmission across 75 km of standard optical fiber in the lab and over a field trial with a metropolitan optical fiber network. This work demonstrates the ability of optical micro-combs to exceed other approaches in performance for the most demanding practical optical communications applications.

Transition 2.0: Digital technologies, higher education, and vision impairment
Authors: Pacheco Edgar
Published: February 2021

This article introduces Transition 2.0, a paradigm shift designed to study and support students with disabilities’ transition to higher education. Transition 2.0 is the result of a qualitative study about how a group of young people with vision impairments used digital technologies for their transition to university. The findings draw from observations, a researcher diary, focus groups, individual interviews, and data from social media. The article discusses a conventional view of transition, referred to here as Transition 1.0, which has dominated disability-related research and service provision in higher education. It counters this view by further developing the conceptual framework for Transition 2.0. The findings expand current conceptual approaches to transition by incorporating in the analysis the role played by digital tools such as social media and mobile devices. They also provide a new lens through which to study and understand student engagement in higher education.

All treatments were sprayed three times starting at R1 or R2. Percent control (C, %), from back-transforming meta-analytic estimates of the log of the ratio ranged from 56.2% (PICO + CYPR) to 76.8% (BIXF + TFLX + PROT). Estimates of mean yield difference (D, kg/ha) between fungicide-treated and untreated plots were greatest for BIXF + TFLX + PROT (1,080) followed by PICO + BENZ (1,010), PYRA + EPOX + FLUX (981.5), AZOX + BENZ (910), TFLX + PROT (891), PICO + TEBU (682), TFLX + CYPR (646) and PICO + CYPR (600). Significant declines in both C and D in a time period as short as four years were detected for AZOX + BENZ (35.3%; 550 kg/ha) and PICO + BENZ (15.5%; 359.8 kg/ha). Variance in D was partially reduced by the inclusion of baseline disease as covariate. In trials where baseline disease was ≥70%, yield was 250 kg/ha greater compared to low baseline disease. Disease control and yield response were generally better in the Southeast, where the frequency of profitable scenarios was 30% higher on average than in the Northwest. Results of this meta-analysis are critical to support decisions during planning fungicide programs.

USP25 is a differentially expressed gene in brain metastatic human breast cancer.
Authors: Mamoor Shahan
Published: February 2021

Metastasis to the brain is a clinical problem in patients with breast cancer (1-3). We mined published microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that the ubiquitin specific peptidase 25, encoded by USP25, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. USP25 mRNA was present at decreased quantities in brain metastatic tissues as compared to primary tumors of the breast. Expression of USP25 in primary tumors was significantly correlated with patient recurrence-free survival. Modulation of USP25 expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain in humans with metastatic breast cancer.

Metastasis to the brain is a clinical problem in patients with breast cancer (1-3). We mined published microarray data (4,5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that coiled-coil domain-containing protein 132, encoded by CCDC132, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. CCDC132 mRNA was present at decreased quantities in brain metastatic tissues as compared to primary tumors of the breast. Importantly, expression of CCDC132 in primary tumors was significantly correlated with patient recurrence-free survival. Modulation of CCDC132 expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain in humans with metastatic breast cancer.

Metastasis to the brain is a clinical problem in patients with breast cancer (1-3). We mined published microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that mitogen-activated protein kinase kinase 1, encoded by MAP2K1, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. MAP2K1 mRNA was present at decreased quantities in brain metastatic tissues as compared to primary tumors of the breast. Importantly, expression of MAP2K1 in primary tumors was correlated with patient overall survival. Modulation of MAP2K1 expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain in humans with metastatic breast cancer.

Differentiating 'attachment difficulties' from autism spectrum disorders and attention deficit hyperactivity disorder: Qualitative interviews with experienced health care professionals
Authors: Coughlan Barry , van IJzendoorn Marinus H. , Woolgar Matt , Weisblatt Emma , Duschinsky Robbie
Published: February 2021

Objectives: Attachment difficulties is an umbrella term often used to describe various forms of non-secure attachment. Differentiating ‘attachment difficulties’ from autism spectrum disorder (hereafter autism) and attention deficit hyperactivity disorder (hereafter ADHD) has been characterised as challenging. Few studies have explored how this happens in practice, from the perspective of the professionals. Design: Qualitative study. Method: We conducted in-depth semi-structured interviews with (n=17) healthcare professionals from five NHS Foundation Trusts in the United Kingdom. Participants were recruited using a combination of snowballing, convenience and purposive sampling. Data were analysed using a thematic approach. Results: We identified six interrelated themes that might reflect difficulties with differential conceptualisation. These include: a clinical lexicon of attachment; approaching attachment with caution; contextual factors; perceived characteristic behaviours; assessing attachment and adjacent supports; spotlighting intervention and dual conceptualisation. Conclusion: Our results indicate some of the ways suspicions around attachment are raised in practice. We advocate for more dialogue between research and practice communities on issues of differential conceptualisation. We call for collaboration between a panel of experts consisting of attachment and neurodevelopmental orientated practitioners and researchers, to clarify issues around differentiating between attachment difficulties, ASD and ADHD.
Developmental Interplay Between Ethnic, National, and Personal Identity in Immigrant Adolescents

Published: February 2021

Developing a personal identity is a core developmental task for all adolescents. Immigrant adolescents need to integrate the meaning that their belonging to their ethnic group and the receiving nation has for them into their personal identity. The purpose of this study was to examine the longitudinal interplay between personal, ethnic, and national identities of a middle school sample of immigrant youth (N = 765, Mage¬ = 12.7 years, SD = 0.6 at T1; 46% girls) enrolled in Greek schools. Data were collected in three waves with repeated measures. To test the link between these identities, two trivariate Cross-Lagged Panel Models were ran, one examining identity exploration and the other examining identity commitment. The results revealed robust within time positive links between ethnic, national and personal identities for both exploration and commitment at all three time-points. There was some evidence that ethnic and national identities were negatively linked longitudinally, and limited support for longitudinal associations between these domains and personal identity. Follow-up analyses suggest that these processes may be specific to second generation youth and that findings may differ by ethnic background. Finally, the findings that emerged are discussed with attention to the socio-political climate in the receiving nation.
Investigating the Association between Grading on a Curve and the Big Fish Little Pond Effect: A Large-Scale Quasi-Experimental Study
Authors: Fleischmann Moritz , Hübner Nicolas , Marsh Herbert , Trautwein Ulrich , Nagengast Benjamin
Published: February 2021

Equally able students have a lower academic self-concept in high-achieving classrooms, the big fish little pond effect (BFLPE). Grading on a curve—providing the best grades to the best students in the class and the worst grades to the worst students—has been speculated to contribute to the BFLPE. However, empirical evidence for this assumption is not conclusive as it stems from correlational studies. We tested the association between the BFLPE and grading on a curve with a natural experiment from the 1970s in which Swedish municipalities were free to abolish grading (N = 9,104). The BFLPE did not differ between nongraded and graded students. Our results suggest that students engage in social comparisons independent of whether or not they are graded.
Using Machine Learning to Investigate the Public’s Emotional Responses to Work from Home During the COVID-19 Pandemic

(Please note this version is before journal proof. The published version might be slightly different.) According to event system theory (Morgeson et al., 2015), the COVID-19 pandemic and resultant stay-at-home orders are novel, critical, and disruptive events at the environmental level that substantially changed people’s work, such as where they work, how they interact with colleagues, and so forth. Although many studies have examined events’ impact on features or behaviors, few studies have examined how events impact aggregate emotions and how these effects may unfold over time. Applying a state-of-the-art deep learning technique (i.e., fine-tuned BERT algorithm), the current study extracted the public’s daily emotion associated with working from home (WFH) at the U.S. state-level over four months (March 01, 2020-July 01, 2020) from 1.56 million Tweets. We then applied discontinuous growth modeling (DGM) to investigate how COVID-19 and resultant stay-at-home orders changed the trajectories of the public’s emotions associated with WFH. Our results indicated that stay-at-home orders demonstrated both immediate (i.e., intercept change) and longitudinal (i.e., slope change) effects on the public’s emotion trajectories. Daily new COVID-19 case counts did not significantly change the emotion trajectories. We discuss theoretical implications for testing event system theory with the global pandemic and practical implications. We also make Python and R codes for fine-tuning BERT models and DGM analyses open-source so that future researchers can verify our findings or adapt and apply the codes in their own studies.
