Strengthening the foundation of educational psychology by integrating construct validation into open science reform
Authors: Flake Jessica Kay
Published: March 2021

An increased focus on transparency and replication in science has stimulated reform in research practices and dissemination. As a result, the research culture is changing: the use of preregistration is on the rise, access to data and materials is increasing, and large-scale replication studies are more common. In this paper, I discuss two problems the methodological reform movement is now ready to tackle given the progress thus far and how educational psychology is particularly well suited to contribute. The first problem is that there is a lack of transparency and rigor in measurement development and use. The second problem is caused by the first; replication research is difficult and potentially futile as long as the first problem persists. I describe how to expand transparent practices into measure use and how construct validation can be implemented to bolster the validity of replication studies.
The role of college bound friends in college enrollment decisions by race, ethnicity, and gender
Authors: Alvarado Steven Elias
Published: March 2021

This study examines the association between college-bound friends and college enrollment using restricted transcript data from the High School Longitudinal Study. Propensity score matching and school fixed effects models suggest that having close college-bound friends is positively associated with enrolling in college. However, Black and Latino male students are much less likely to benefit from having college-bound friends than others, suggesting that structural and cultural factors that are tied to race, ethnicity, and gender may limit the beneficial potential of friends, especially for these male Black and Latino students. Implications for addressing racial and ethnic disparities in college enrollment and for the role of friends in college enrollment decisions are discussed.

Published: March 2021

This paper reports on the effectiveness of Interactive Reading Comprehension Teaching (IRCT) in improving the oral English communication ability of Prince of Songkla University (PSU) undergraduates. It is based on a pre- and post-test quasi-experimental study employing IRCT, composed of self–study reading assignments and a structured peer-teaching project. The participants who were purposively sampled to partake in the study included 105 second- and third-year undergraduates from various faculties who were enrolled in a functional reading course, of which 46 was assigned to the control group and 49 was treated as the experimental group. One-on-one and group oral assessments were administered to both groups at the end of the course after IRCT implementation. The results showed IRCT had a very positive effect on the oral communication skills of the students in the experimental group, significantly improving their confidence and motivation toward speaking English. The students’ opinions from a questionnaire also revealed high speaking improvement, reinforced by evidence from close observations, interviews, and student work samples. IRCT was, therefore recommended as a reading-based approach to improving students’ oral English communication.
Lifestyle-Related Shaming: The Significance of Reintegrative Shaming on Drug Relapse Offenders in Indonesia
Authors: Amry Muh Ardila , Meliala Adrianus
Published: March 2021

In statistical calculations, drug abusers with the status of drug relapse in Indonesia reached 70% in 2019 (National Narcotics Agency: 2019). This condition illustrates that the social rehabilitation mechanism for drug abusers in Indonesia still has the opportunity to present shameless. Therefore, this study seeks to see the significance of Lifestyle-related shaming as an important part of the mechanism for implementing shaming for the shameless, especially drug relapse offenders in urban areas. This study was conducted based on the analysis of John Braithwaite's shaming theory which states that the public's response to perpetrators is divided into 2 (two) namely reintegrative shaming which means re-acceptance of the shameless by giving shame to them and stigmatization which means treating the shameless by giving a negative stigma permanently. The method used here was literature review by utilizing and trying to develop existing theories (grounded theory) by presenting concepts (variables) in accordance with the affordability of study data so as to produce new findings regarding the significance of Lifestyle-related shaming in its role for drug relapse offenders. Lifestyle-Related Shaming is part of a combination of reintegrative shaming theory, desistance theory and routine activity theory. In the literature study conducted, the combination of (3) three macro theories produces Lifestyle-related shaming which is closely related to urban lifestyle. It is expected that later, this study will be able to provide a broad understanding to the government to prepare the best program for solving shameless phenomenon, especially drug abuse in Indonesia. Furthermore, it is also useful in science as a basis for the application of shaming in Indonesia.
Does Diary Mode Matter in Time-Use Research?
Authors: Chatzitheochari Stella , Mylona Elena
Published: March 2021

Recent years have witnessed an increasing interest in the use of new technologies for time-use data collection, driven by their potential to reduce survey administration costs and improve data quality. However, despite the steady growth of studies that employ web and app time diaries, there is little research on their comparability with traditional paper-administered diaries that have long been regarded as the “gold standard” for measurement in time-use research. This paper rectifies this omission by investigating diary mode effects on data quality and measurement, drawing on data from a mixed-mode large-scale time diary study of adolescents in the United Kingdom. After controlling for selection effects, we find that web and app diaries yield higher quality data than paper diaries, which attests to the potential of new technologies in facilitating diary completion. At the same time, our analysis of broad time-use domains does not find substantial mode effects on measurement for the majority of daily activity categories. We conclude by discussing avenues for future methodological research and implications for time-use data collection.
Hartz IV and educational attainment: Investigating the causal effect of social benefit reform on intergenerational inequalities in Germany
Authors: Trinh Nhat An
Published: March 2021

This study examines how far radical and still contested changes to Germany’s unemployment and social benefit system in 2005 affected the intergenerational transmission of disadvantage for children of benefit recipients. Using difference- in-differences estimation and data from the Socio-Economic Panel, I examine whether inequalities in secondary school attainment increased after the implementation of the so-called ‘Hartz IV’ reform. The findings suggest that children whose parents receive the newly created scheme ALGII instead of Arbeitslosenhilfe for unemployment assistance experienced a significant and considerable drop in their chances to attend the Gymnasium. Changes in parents’ socio-demographic characteristics due to stricter eligibility criteria and lower household incomes as a result of lower benefit levels account for the observed decline. By contrast, reductions in parental life satisfaction related to increased benefit conditionality and stigma are unlikely to mediate the reform’s documented effects. Focussing on an important outcome in Germany’s highly stratified educational system, the study is the first to provide evidence on the intergenerational effects of Hartz IV , shedding light on the role of social security and welfare institutions in the transmission of inequalities from parents to their children.
Die Wirtschaft, durch Strom gelesen
Authors: Russ Daniela
Published: March 2021

Ein energiewirtschaftliches Aufschreibesystem bezeichnet die Techniken und Medien, mit denen Energieflüsse in der Gesellschaft aufgezeichnet werden. An der Entwicklung von Elektrizitätssystemen zwischen 1880-1930 zeigt der Text, wie Techniken der Dokumentation und Kontrolle die technische, wirtschaftliche und politische Aneignung der Elektrizität informiert haben. Während das neunzehnte Jahrhundert von 'Kraftquellen' sprach, die lokal angeeignet wurden, geht es im zwanzigsten Jahrhundert um die physikalisch-ökonomische Logik der Verteilung von 'Energieflüssen'. Der Text argumentiert, dass die Aufzeichnung eines fließenden Arbeitskraftreservoirs – der Kraftwirtschaft – durch die großen elektrischen Systeme für die Vorstellung dieser neuen Energiewirtschaft wesentlich war.

Dalam sejarahnya istilah Public Relations sebagai sebuah teknik menguat dengan adanya aktivitas yang dilakukan oleh pelopor Ivy Ledbetter Lee yang tahun 1906 berhasil menanggulangi kelumpuhan industri batu bara di Amerika Serikat dengan sukes. Atas upayanya ini ia diangkat menjadi The Father of Public Relations. Perkembangan public relations sebenarnya bisa dikaitkan dengan keberadaan manusia. Unsur-unsur memberi informasi kepada masyarakat, membujuk masyarakat, dan mengintegrasikan masyarakat, adalah landasan bagi masyarakat public relations. Tujuan, teknik, alat dan standar etika berubah-ubah sesuai dengan berlalunya waktu. Misalnya pada masa suku primitif mereka menggunakan kekuatan, intimidasi atau persuasi ntuk memelihara pengawasan terhadap pengikutnya. Atau menggunakan hal-hal yang bersifat magis, totem (benda-benda keramat), taboo (hal-hal bersifat tabu), dan kekuatan supranatural. Penemuan tulisan akan membuat metode persuasi berubah. Opini publik mulai berperan. Ketika era Mesir Kuno, ulama merupakan pembentuk opini dan pengguna persuasi. Pada saat Yunani kuno mulai dikembangkan Olympiade untuk bertukar pendapat dan meningkatkan hubungan dengan rakyat. Evaluasi mengenai pendapat atau opini publik merupakan perkembangan terakhir dalam sejarah kemanusiaan.

The Veterinary Internship and Residency Matching Program (VIRMP) recently revised its electronic standardized letter of reference (SLOR) to improve the quality and usefulness of the data obtained from it and to enhance the relevance of non-cognitive and cognitive candidate attributes assessed. We used a stepwise process including a broad survey of SLOR readers and writers, analysis of past SLORs, and a multi-wave iterative revision that included key stakeholders, such as residency and internship program directors from academia and private practice. Data from the SLOR survey and analysis of past SLOR responses identified opportunities to improve applicant differentiation, mitigate positive bias, and encourage response consistency. The survey and other analytics identified and confirmed performance domains of high relevance. The revised SLOR assesses four performance domains: knowledge base and clinical skills, stress and time management, interpersonal skills, and personal characteristics. Ratings within the revised SLOR are predominantly criterion-referenced to enhance discernment of candidate attributes contained within each domain. Questions assessing areas of strength and targeted mentoring were replaced with free-text boxes, which allow writers to comment on positive and neutral/negative ratings of attributes within domains. Minor revisions were made to certain questions to enhance readability, streamline responses, or address targeted concerns identified in the SLOR survey or stakeholder review. The revised SLOR was deployed in the 2020 VIRMP; data from a survey of writers ( n = 647) and readers ( n = 378) indicate that the redesign objectives were achieved.
Investigating the Effects of Error Management Training versus Error Avoidance Training on the Performance of Veterinary Students Learning Blood Smear Analysis
Authors: Meritet Danielle , Gorman M. Elena , Townsend Katy L. , Chappell Patrick , Kelly Laura , Russell Duncan S.
Published: March 2021

Conventional veterinary training emphasizes correct methodologies, potentially failing to exploit learning opportunities that arise as a result of errors. Error management training (EMT) encourages mistakes during low-stakes training, with the intention of modifying perceptions toward errors and using them to improve performance in unfamiliar scenarios (adaptive transfer). Herein, we aimed to determine the efficacy of EMT, supplemented by a metacognitive module, for veterinary students learning blood smear preparation and interpretation. Our hypothesis was that EMT and metacognition are associated with improved adaptive transfer performance, as compared with error avoidance training (EAT). A total of 26 students were prospectively enrolled in this double-blind study. Performance was evaluated according to monolayer area, smear quality, cell identification, calculated white blood cell differential counts, and overall application/interpretation. Students were trained with normal canine blood and static photomicrographs. Participants tested 72 hours after training demonstrated improved performance in a test that directly recapitulated training (Wilcoxon matched-pairs signed-rank test; two-tailed p all ≤ .001). There were no significant differences between EAT and EMT in this test (Mann–Whitney U test and Welch’s t-test; two-tailed p ≥ .26) or in short- and long-term adaptive transfer tests ( p ≥ .22). Survey data indicate that participants found errors to be a valuable element of training, and that many felt capable of accurately reflecting on their own performance. These data suggest that EMT might produce outcomes comparable to EAT as it relates to blood smear analysis.
Малоизвестные страницы публицистики Русского Зарубежья: «Русские уголки» Франции в очерках Константина Парчевского
Authors: Mianowska Joanna
Published: March 2021

Очерки малоизвестного эмигрантского публициста первой волны русского исхода ХХ века К.К. Парчевского По русским углам печатались в парижской газете «Последние новости» с 9 августа 1936 года по 4 июля 1937 и вышли отдельной книгой в 2002 году. У каждого из них свое лицо (их свыше 30). Они вписываются в раздел поэтики, имеющий своим предметом анализа образы географического пространства в индивидуальном творчестве. Эта поэтика сложилась уже в каче-стве академической науки как раздел культурологии и часть литературоведения. Очерки Парчевского составлены по географическому принципу, но представляют также интерес и в отношении статистики. Их фактология и информационность позволяют сделать вывод о наличии нового угла зрения и нового ракурса о судьбах русской диаспоры в разных уголках Франции. В анализируемых очерках осмыслена природная данность и историко-творческая заданность этого периода.
Клиповые мемные тексты. Часть 1. Иконоидные тексты
Authors: Makarowska Olga
Published: March 2021

В данной статье рассматривается клиповый иконоидный текст как один из новых видов текстов, создаваемых и функционирующих в Интернете. Основными составляющими иконоидных текстов являются мемы. Подчеркивается, что интерес к исследованию мемов велик, но при этом мемы и мемосфера слабо изучены. Указывается, что ученые приписывают интернет-мемам черты мемов, которые выделил Ричард Докинз в своей книге Эгоистичный ген (1976), но многие интернет-мемы ими не обладают. При уточнении понятия интернет-мем учитывается ряд особенностей мемов. Например, что мемы используются не только в виртуальной, но и реальной действительности; что мемы могут создаваться не основе шаблона и без него; что мемами могут являться картинки, слова, знаки и т.д.; что мемы могут содержать другие мемы, а также могут быть анимированными. Представляется общая типология интернет-мемов. В соответствии с ней мемы разделяются на визуальные, аудиальные и аудиовизуальные. Приводится также классификация мемов с визуальной и вербальной частью, которые получают названия иконоид и текстонсоответственно. Введение этих понятий необходимо для точного описания главных компонентов мемов. Ранее Катажина Марак обращала внимание на то, что отсутствует лексика для точного описания мемов. Обращается внимание на основные функции клипового иконоидного текста, т.е. релаксационную, интерактивную и когнитивную. Выделяются общие и отличительные признаки клипового иконоидного текста и музыкального видеоклипа. В работе раскрывается механизм создания иконоидных текстов, выявляются их особенности и описываются главные признаки.

Wraz z przejściem polskiej i rosyjskiej gospodarki na kapitalistyczny model rozwoju gospodarczego w języku polskim i rosyjskim pojawiło się nowe słownic-two odnoszące się do tej sfery, głównie o anglojęzycznej proweniencji. Zasoby leksykalne obu języków wzbogaciły się o kalki frazeologiczne złoty spadochron (parasol) i золо-той парашют, rozpowszechnione w środowisku ekonomiczno-finansowo-biznesowym. Internacjonalny charakter tego typu reproduktów świadczy o globalizacji praw i dzia-łań w sferze finansowej. Za sprawą elit symbolicznych (dziennikarzy), wypowiadają-cych się na łamach prasy niespecjalistycznej (ogólnopolskiej), frazeologizmy te znane są także szerokiemu kręgowi odbiorców-niespecjalistów. W polszczyźnie i ruszczyźnie, jak zaświadczają to konteksty w prasie niespecjalistycznej (2019/2020), wyrażenie to zaczyna też funkcjonować w dodatkowym nieekonomicznym (nieterminologicznym) znaczeniu.

Kacang panjang sangat disukai hama.  Hama yang sering menyerang adalah ulat penggerek polong (Maruca testulalis), tungau merah (Tetranychus bimaculatus), dan kutu daun (Aphis spp.). Upaya menekan intensitas kerusakan akibat serangan hama pada pertanaman adalah dilakukannya pengendalian populasi hama. Penggunaan insektisida sintetik (pestisida) dalam pengendalian hama perlu dikurangi dengan cara beralih pada insektisida yang berbahan aktif jamur entomopatogen. Jamur Entompatogen merupakan jamur yang menginfeksi serangga dengan cara masuk ketubuh inang melalui kulit, saluran pencernaan, spirakel, dan lubang lainnya. Jamur Entomopatogen yang efektif mengendalikan hama penting tanaman adalah; Leucanicillium lecanii, Beuveria sp, Metarhizium anisoplae, Nomuraea rileyi, Paecilomyces fumosoroseus, Aspergilus parasiticus dan Vericillium lecanii. Penelitian ini bertujuan untuk meneliti adanya pertumbuhan koloni jamur entomopatogen pada serangga umpan dari pertanaman kacang panjang (Vigna sinensis L.) di Desa Bukit Batu Jalur 30 Kabupaten Ogan Komering Ilir. Penelitian ini dilaksanakan di Laboratorium Hama dan Penyakit Tumbuhan Fakultas Pertanian Universitas Palembang.  Penelitiaan ini dilakukan selama 3 bulan yaitu pada bulan Februari 2019 sampai dengan April 2019. Penelitian ini menggunakan metode purposive sampling dan pengambilan sampel tanah dilakukan dengan menentukan lokasi dan lima titik sampel secara diagonal. Hasil penelitian menunjukan bahwa di lahan pertanaman kacang panjang (Vigna sinensis L.)  desa Bukit Baru Jalur 30 Kabupaten Ogan Komering Ilir terdapat jamur Entomopatogen dan terdapat tiga gejala yang terdapat pada serangga umpan yang terinfeksi jamur Entomopatogen.  Mortalitas serangga umpan maksimum adalah 4 ekor (40%) dan minimum 1 ekor (10%) untuk masing-masing sampel.

Authors: Aisah Aisah
Published: March 2021

Desa Rantau Durian I juga memiliki potensi pengembangan tanaman baik di sector tanaman pangan maupun tanaman perkebunan, sebagian besar wilayah Desa Rantau Durian I merupakan lahan produksi atau daerah persawahan.  Bila dilihat dari sisi pengairan sawah merupakan sawah tadah hujan yang hanya berproduksi satu kali dalam setahun, hal ini yang menjadi penyebab beberapa sawah yang ada di desa tersebut telah beralih fungsi sebagai lahan perkebunan tanaman karet yang dinilai oleh masyarakat lebih menguntungkan.  Tetapi permasalahan utama tanaman karet saat ini adalah produksi karet yang rendah dan bahan baku yang dihasilkan mutunya juga masih rendah sehingga harga yang diterima petani relative rendah.  Kondisi inilah yang membuat masyarakat di desa tersebut mempunyai kegiatan rumah tangga yang dapat menunjang perekonomian mereka setelah pulang dari menyadap karet kurang lebih tiga sampai empat jam, sehingga sisa waktu dapat digunakan untuk membuat tirai.  Tujuan penelitian adalah : 1). Untuk mengetahui margin harga pada pemasaran tirai di tingkat Desa Rantau Durian I Kecamatan Lempuing Jaya OKI. 2). Untuk mengetahui berapa besar pendapatan tirai terhadap pendapatan dan konsumsi keluarga petani jika dilihat dari sudut pandang waktu pemasaran di bulan-bulan hari besar (lebaran, tahun baru).  Hasilnya menunjukkan bahwa margin pemasaran pada penjualan eceran dan partai besar berbeda.  Di mana penjualan eceran atau petani menjual langsung ke konsumen adalah Rp18.000,-.  Sedangkan petani menjual ke partai besar dengan volume banyak adalah Rp 15.000,- , maka margin pemasaran adalah sebesar Rp 3.000,-.  Kontribusi kerajinan tirai terhadap pendapatan keluarga petani di Desa Rantau Durian I yaitu sebesar 24 %.  Sedangkan kontribusi tirai terhadap konsumsi keluarga petani di Desa Rantau Durian I yaitu sebesar 40 %.

Investigation of Internal Erosion Susceptibility of Core Soil from Three Dams
Authors: Jalil Ahmed , Benamar Ahmed , Ebn Touhami Mohamed
Published: March 2021

Laboratory tests on internal erosion of cohesionless soils are often performed on cells submitted to a controlled seepage. The cell dimension depends on the grain size of tested soil and must meet the geometric and hydraulic scale requirements as regards to the modeled process. Three specimens collected from different zoned dams in Morocco were characterized for their geotechnical properties and dispersion sensitivity, and then submitted in two different cells to internal erosion (Hole Erosion Test) under controlled seepage. The erosion kinetics was measured, and soil classification was assessed as regards to the useful engineering guidelines. The results showed that specimen dimensions can affect the erosion parameters which are quite different from a cell to another. Even though the derived erosion coefficient values are different from the two testing cells, the classification of the three soils regarding the susceptibility to erosion, using engineering guidelines, indicated that the tested soils fall overall in neighboring erosion classifications. However, the soil involving the lower clay content provided the greatest resistance against internal erosion.

Pro12Ala polymorphism in PPAR-γ gene of impaired glucose tolerance subjects in Bangladeshi population
Authors: Faruque Md Omar , Saha Ayan , Khan Imran , Hassan Zahid , Ali Liaquat
Published: March 2021

Pro12Ala polymorphism in PPAR-gamma (PPAR-γ) gene is associated obesity and hyperglycemia in some races, but controversy exists for other races. In this study, 113 impaired glucose tolerance (IGT) and 113 healthy control subjects were recruited. Wild type (CC), heterozygous (CG), and homozygous (GG) variants of Pro16Ala polymorphism of PPAR-γ (rs1801282) were analyzed using Chi-square test, and the polymorphism was found significantly (p=0.05, Χ2=5.875) associated with IGT subjects. Allele frequency also shows significant association with IGT subjects in the Chi-square test (p=0.026, Χ2=2.248). When the waist-hip ratio was reanalyzed according to genotype variation, the waist-hip ratio was found significantly higher among subjects with heterozygous and homozygous variants of pro16Ala polymorphism. Therefore, our study concluded that PPAR-γ P12A variants might be associated with impaired glucose tolerance. It is also documented that higher waist to hip ratio in IGT subjects may associate with heterozygous (CG) and homozygous (GG) variants of Pro12Ala mutation in the PPAR-γ gene.

Published: March 2021

Background: Rickettsial diseases are difficult to diagnose in Bangladesh due to low index of suspicion and lack of diagnostic facilities in most laboratories especially in rural areas. Immunofluorescence assay (IFA) is the gold standard serological test for diagnosis of Rickettsial diseases. For serological diagnosis of rickettsial diseases, use of filter paper is an inexpensive and convenient method for collecting, storing, and transporting of blood samples with little space without refrigeration. Current study shows that the rickettsial diseases were present in febrile patients in Bangladesh. The study also compared the results of direct serum by IFA and filter paper serum spot followed by IFA as an alternative way of testing frozen samples.

Materials and Methods: This observational study for evaluation of rickettsial diseases from direct serum by IFA and sera dried on blotting paper followed by IFA at the department of Virology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. A total of 152 patients’ sera were selected by systemic random sampling of every 3rd sera of 556 febrile patients who were tested negative for dengue and or Chikungunya virus infection. Forty cases were confirmed by IFA from direct sera. In addition, 60 samples were selected from 152 sera by systemic random sampling of every 3rd sera for blotting on filter paper for further IFA test. Out of 60 sera, 35 were confirmed by IFA from direct sera and of the 35 confirmed positive cases, 31(88.6%) were positive by IFA after blotting paper assay. Taking the IFA of direct sera as gold standard test, the sensitivity, specificity, positive predictive value and negative predictive value of IFA from blotting paper eluted sera were 88%, 100%, 100% and 86% respectively.

Conclusion: The study showed the use of filter paper is an inexpensive and convenient method for storing and transporting samples for serological tests like IFA in diagnosis of rickettsial diseases.

Thomas Carlyle, Scotland's Migrant Philosophers, and Canadian Idealism, c. 1870–1914
Authors: Jordan Alexander
Published: March 2021

That the great Scottish man of letters Thomas Carlyle (1795–1881) exercised a formative influence over late-nineteenth- and early-twentieth-century ‘British Idealism’ has long been recognized by historians. Through works such as Sartor Resartus (1833–1834), Heroes and Hero-Worship (1841), Past and Present (1843), and Latter-Day Pamphlets (1850), Carlyle transmitted his ideas regarding the immanence of the divine in nature and man, the infinite character of duty, and the ethical role of the state to a generation of subsequent philosophers. The following article will extend this insight, arguing that through the agency of an array of migrant Scottish intellectuals, Carlyle's writings made an equally significant contribution to the development of Idealism in English-speaking Canada.

Cutaneous Melanoma: Mutational Status and Potential Links to Tertiary Lymphoid Structure Formation

Recent advances in immunotherapy have enabled rapid evolution of novel interventional approaches designed to reinvigorate and expand patient immune responses against cancer. An emerging approach in cancer immunology involves the conditional induction of tertiary lymphoid structures (TLS), which are non-encapsulated ectopic lymphoid structures forming at sites of chronic, pathologic inflammation. Cutaneous melanoma (CM), a highly-immunogenic form of solid cancer, continues to rise in both incidence and mortality rate, with recent reports supporting a positive correlation between the presence of TLS in melanoma and beneficial treatment outcomes amongst advanced-stage patients. In this context, TLS in CM are postulated to serve as dynamic centers for the initiation of robust anti-tumor responses within affected regions of active disease. Given their potential importance to patient outcome, significant effort has been recently devoted to gaining a better understanding of TLS neogenesis and the influence these lymphoid organs exert within the tumor microenvironment. Here, we briefly review TLS structure, function, and response to treatment in the setting of CM. To uncover potential tumor-intrinsic mechanisms that regulate TLS formation, we have taken the novel perspective of evaluating TLS induction in melanomas impacted by common driver mutations in BRAF, PTEN, NRAS, KIT, PRDM1, and MITF. Through analysis of The Cancer Genome Atlas (TCGA), we show expression of DNA repair proteins (DRPs) including BRCA1, PAXIP, ERCC1, ERCC2, ERCC3, MSH2, and PMS2 to be negatively correlated with expression of pro-TLS genes, suggesting DRP loss may favor TLS development in support of improved patient outcome and patient response to interventional immunotherapy.

The rumen microbiome plays a vital role in providing nutrition to the host animal, thereby influencing ruminant production. Despite its importance, it is not fully understood how variation in the ruminal bacteria community composition influences dry matter intake (DMI), milk yield and ruminal fermentative parameters in dairy cows, especially during freshening period. Here, we hypothesized that during early lactation, high DMI cows having a different ruminal microbiota than low DMI cows, and that this difference persists over time. To test this, we enrolled 65 fresh and determinzed their DMI using an auto-feed intake recording system. Fourteen days after calving, the 10 animals with the lowest (LFI) and the 10 animals with the highest (HFI)-average DMI were selected for further analysis. Rumen fluid was collected from these two cohorts at 1 (Fresh1d) and 14 days (Fresh14d) after calving and their ruminal microbiota were assessed using 16S rRNA sequencing. Volatile fatty acid (VFA) concentrations were also quantified. Comparison of the ruminal microbiotas between Fresh1d and Fresh14d showed that Fresh14d cows had a significantly higher relative abundance of VFA—producing microbes (P < 0.05), such as Prevotella_7 and Succinivibrionaceae_UCG-001. This was commensurate with the concentrations of acetate, propionate, butyrate, valerate and total VFAs, were also significantly (P < 0.05) increased in Fresh14d cows. We also found that the differences in the ruminal microbiota between LFI and HFI cows was limited, but DMI significantly altered (P < 0.05) the relative proportion of bacteria in the families Coriobacteriaceae, and Succinivibrionaceae. Furthermore, specific operational taxonomic units belonging to the Anaeroplasma was significantly (P < 0.05) correlated with DMI and milk yield. Taking together, our findings provide a framework for future studies of freshening period cow that seek to better understand the role of the ruminal microbiota during this critical period in the lactation cycle.
