La defensa del patrimonio forestal público en la Comunidad Valenciana
Authors: Montiel Molina Cristina
Published: September 2018

La defensa del patrimonio forestal público llevada a cabo por los ingenieros de montes en la región valenciana desde finales del siglo xix, se ha concretado en el saneamiento del estado legal de los predios públicos y en la adquisición de nuevas fincas con objeto de corregir y ampliar el perímetro de aquéllos o de incrementar el patrimonio público. En el esclarecimiento de las condiciones legales de los montes públicos han desempeñado un papel fundamental los actos de deslinde y amojonamiento, así como las inscripciones en los registros de la propiedad. Por otra parte, los objetivos que han guiado la política de adquisiciones de terreno forestal han estado generalmente relacionados con la ejecución de trabajos de corrección hidrológico-forestal o con la recuperación de fincas forestales en comarcas deprimidas.

Algumas práticas contábeis podem permitir maior discricionariedade, podendo ser utilizadas para gerenciar as informações. Esse aspecto pode implicar maiores esforços dos auditores independentes na identificação de possíveis riscos para validação dessas informações, aumentando o valor dos honorários. Assim, o objetivo desse estudo foi verificar a relação entre a adoção de práticas contábeis discricionárias, como o valor justo, mediante cálculo do fluxo de caixa descontado, e a aplicação do cálculo de impairment, com os honorários de auditoria. A pesquisa foi realizada em empresas brasileiras não financeiras de capital aberto, no período de 2010 a 2014, utilizando teste de diferença de média e regressão em painel. Os resultados indicaram haver uma relação significativa e positiva entre práticas contábeis discricionárias e os honorários de auditoria, mais propriamente com relação à adoção do valor justo. Também se confirmou a relação de alguns determinantes dos honorários, como: tamanho da empresa auditada, risco, complexidade, lucratividade, contratação de Big Four, adoção de práticas de governança corporativa e rodízio das firmas de auditoria. Deste modo, a pesquisa contribui para uma reflexão do uso de práticas contábeis subjetivas, capazes de impactar positivamente na utilidade das demonstrações contábeis, mas que podem ser fatores determinantes dos custos da informação na relação agente-principal. Além disso, o estudo amplia as pesquisas sobre determinantes dos honorários, evidenciado os aspectos de riscos observados pelos auditores, os quais também podem ser utilizados pelos investidores nas avaliações de investimentos, e pelos reguladores na identificação de parâmetros para observação de pagamentos anormais desses honorários.

Planning and Scheduling in Additive Manufacturing
Authors: Dvorak Filip , Micali Maxwell , Mathieug Mathias
Published: September 2018

Recent advances in additive manufacturing (AM) and 3D printing technologies have led to significant growth in the use of additive manufacturing in industry, which allows for the physical realization of previously difficult to manufacture designs. However, in certain cases AM can also involve higher production costs and unique in-process physical complications, motivating the need to solve new optimization challenges. Optimization for additive manufacturing is relevant for and involves multiple fields including mechanical engineering, materials science, operations research, and production engineering, and interdisciplinary interactions must be accounted for in the optimization framework.

In this paper we investigate a problem in which a set of parts with unique configurations and deadlines must be printed by a set of machines while minimizing time and satisfying deadlines, bringing together bin packing, nesting (two-dimensional bin packing), job shop scheduling, and constraints satisfaction. We first describe the real-world industrial motivation for solving the problem. Subsequently, we encapsulate the problem within constraints and graph theory, create a formal model of the problem, discuss nesting as a subproblem, and describe the search algorithm. Finally, we present the datasets, the experimental approach, and the preliminary results.
Graphics algorithm for deriving atmospheric boundary layer heights from CALIPSO data
Authors: Liu Boming , Ma Yingying , Liu Jiqiao , Gong Wei , Wang Wei , Zhang Ming
Published: September 2018

Abstract. The atmospheric boundary layer is an important atmospheric feature that
affects environmental health and weather forecasting. In this study, we
proposed a graphics algorithm for the derivation of atmospheric boundary
layer height (BLH) from the Cloud-Aerosol Lidar and Infrared Pathfinder
Satellite Observations (CALIPSO) data. Owing to the differences in scattering
intensity between molecular and aerosol particles, the total attenuated
backscatter coefficient 532 and attenuated backscatter coefficient 1064 were
used simultaneously for BLH detection. The proposed algorithm transformed the
gradient solution into graphics distribution solution to overcome the effects
of large noise and improve the horizontal resolution. This method was then
tested with real signals under different horizontal smoothing numbers (1, 3,
15 and 30). Finally, the results of BLH obtained by CALIPSO data were
compared with the results retrieved by the ground-based lidar measurements.
Under the horizontal smoothing number of 15, 12 and 9, the correlation
coefficients between the BLH derived by the proposed algorithm and
ground-based lidar were both 0.72. Under the horizontal smoothing number of
6, 3 and 1, the correlation coefficients between the BLH derived by graphics
distribution method (GDM) algorithm and ground-based lidar were 0.47, 0.14
and 0.12, respectively. When the horizontal smoothing number was large (15,
12 and 9), the CALIPSO BLH derived by the proposed method demonstrated a good
correlation with ground-based lidar. The algorithm provided a reliable result
when the horizontal smoothing number was greater than 9. This finding
indicated that the proposed algorithm can be applied to the CALIPSO satellite
data with 3 and 5 km horizontal resolution.

Published: September 2018

Abstract. The sources and atmospheric chemistry of gas-phase organic acids are
currently poorly understood, due in part to the limited range of measurement
techniques available. In this work, we evaluated the use of SF6-
as a sensitive and selective chemical ionization reagent ion for real-time
measurements of gas-phase organic acids. Field measurements are made using
chemical ionization mass spectrometry (CIMS) at a rural site in Yorkville,
Georgia, from September to October 2016 to investigate the capability of this
measurement technique. Our measurements demonstrate that SF6-
can be used to measure a range of organic acids in the atmosphere. One-hour
averaged ambient concentrations of organic acids ranged from a few parts per
trillion by volume (ppt) to several parts per billion by volume (ppb). All
the organic acids displayed similar strong diurnal behaviors, reaching
maximum concentrations between 17:00 and 19:00 EDT. The organic acid
concentrations are dependent on ambient temperature, with higher organic acid
concentrations being measured during warmer periods.

Published: September 2018

Abstract. Diel vertical migration (DVM) is a survival strategy adopted by zooplankton, that was investigated in the Corsica Channel using ADCP data, from April 2014 to November 2016. The principal aim of the study is to characterize migratory patterns and biomass temporal evolution along the water column. The ADCP measured vertical velocity and echo intensity in the water column range between about 70 m and 390 m (the bottom depth is 443 m). In addition, net samples were taken during summer 2015 at the same location. During the investigated period, biomass had a well-defined daily and seasonal cycle, with peaks occurring in late winter–spring, when the stratification of water column is weaker. Biomass evolution along the whole water column is well correlated with primary production estimated with satellite data. Blooming and no-blooming periods have been identified and studied separately. During the no-blooming period biomass was most abundant in the surface and the deep layers, while during the blooming period the surface maximum disappeared and the deep layer with high biomass became thicker. These two layers are likely to correspond to two different zooplanktonic communities. Nocturnal DVM appears to be the main pattern during both periods, but also reverse and twilight migration are detected. Nocturnal DVM was more evident at mid-water than near in the deep and the surface layers. DVM occurred with different intensities in blooming and no-blooming periods, and phenomena like nocturnal sinking were found to be stronger during the blooming period. One of the main outcomes is that the principal drivers for DVM are light intensity and stratification, but also others are taken in consideration.
Language and Content Outcomes of CLIL and EMI: A Systematic Review

Published: September 2018

Around the world, language teachers are shifting to content-based instruction (CBI) as a way to teach English, most commonly in the form of Content and Language Integrated Learning (CLIL) or English-Medium Instruction (EMI). With the spread of CBI around the world, it is important to understand how this shift in teaching has affected student outcomes. Using a systematic literature review approach, this study examines current literature on the effect of CBI on language and content outcomes. Twenty-five articles met the inclusion criteria for this study and were examined. The results show mixed findings on the effectiveness of CBI on student outcomes, with the majority of studies showing either positive or neutral effects for CBI when compared with non-CBI classrooms. However, the study also reveals multiple methodological issues that cause difficulties for any strong conclusions about CBI to be made. In addition, while CLIL in Spain has received a lot of research attention, other countries remain understudied. Therefore, this study concludes with a call for future research of CBI outcomes that examine a variety of countries and account for the methodological flaws identified.
Funny in the Bones: The Neural Interrelation of Humor, Irony, and Metaphor as Evolved Mental States
Authors: Hellberg Dustin
Published: September 2018

This article relates the structural and neural similarities of the sets of humor, irony, and metaphor (HIM sets) as heuristics that span self and self–other cognitive functions as they relate to theory of mind (ToM). These phenomena share common neural pathways in the medial prefrontal cortex, frontal gyrus, and tempero-parietal junction and they also share a similar operative pattern relating to relational incongruity embodied in temporal mental experience based on the human mind's embodied self–other intentional projection capacity. They also function as socio-cooperative interactions between individuals (egocentric) and groups (allocentric). That these share a similar structure, neural function, and social function seems to warrant the hypothesis that they are related to earlier evolutionary functions.
‘I Have a Crush on Your Skeleton’: Ecophobia, the Blues, and Captain Beefheart's Lewd(ic) Ecology
Authors: Guimarães João Paulo
Published: September 2018

In this article, I show that, tactfully aware of the artificiality of the gender norms that inform the logic of desire and devilish violence of the blues, Captain Beefheart makes purposed use of that genre's simplistic sexual framework as a means to negate masculinist and anthropocentric discourses of control and explore the more demonic territory of nature “in-itself.” Unlike the Lovecraftian heroes that traditionally investigate “inhuman” environments, Beefheart does not recoil in terror before their darkness, performing, rather, a masochistically ludic exploration of the human-nature gap, the reconsideration of which remains an ecological imperative.

Predictability of Visual Processes on Performance in Geometry
Authors: Weckbacher Lisa Marie , Okamoto Yukari
Published: September 2018

There is a consensus that certain cognitive abilities and mathematics performance are related. This link also extends to geometry. Surprisingly, however, little research has examined specific aspects of cognition that may contribute to successful performance in geometry, particularly at the secondary level. In this study, we explored in what ways, if any, three types of cognitive abilities (spatial visualization, mental rotation, and imagery ability) and one’s preferred cognitive style (a visualizer or verbalizer style) might be related to geometry. High school students who have already taken at least two quarters of geometry participated in the study (N = 114). The results showed that the two spatial measures, not cognitive style, were significantly correlated to geometry performance. Of the two spatial measures, paper folding, not mental rotation, emerged as a significant predictor of geometry performance. The interpretations of the current findings as well as educational implications are discussed.

Authors: Lin Chun-wen
Published: September 2018

The primary aim of this study was two-fold: 1) to identify information communication technology (ICT) acceptance of kindergarten parents that influence parents’ deliberative belief and empowerment by applying the socio-technical systems theory as theoretical framework; and 2) to examine the mediated effect of deliberative belief between ICT acceptance and empowerment. A total of 949 elementary school and kindergarten parents in Taiwan were asked to complete questionnaire about their ICT acceptance, deliberative belief, and empowerment. Structural equation modeling (SEM) was utilized to evaluate the validity of structural/ latent model. The results revealed that deliberative belief, mediate the relationship between the ICT acceptance and empowerment among parents. ICT acceptance had effect on deliberative belief, and deliberative belief had the effects on empowerment. According to this information, it is recommended that school administrators should encourage parents and teachers together to improve and enhance their deliberative belief, ICT acceptance that may lead to more positive parents’ empowerment in school governance.

Published: September 2018

In many sports like volleyball, jumping, balance and explosive strength which are biomotor abilities have become more important day by day to succeed. Athletes focus on games at game period so the time that they spend for improving their biomotor abilities can be less. Therefore, performance that obtained in preparation period and sustaining that performance in whole season affect significantly team rank at the end of the season.

In the lights of these informations, the affect of amount of jumps with respect to different positions was investigated in major league of Turkey in 2013-2014. There were 149 female volleyball players between the ages 17-27 (age 24.19 ± 2.42) in this study. 12 teams competed with each other and 125 games that is 455 sets were evaluated. Moreover; videos were analyzed three times by experts. Number of jumps in serve, block, spike and setting were recorded. Spearman Brown Order Differential Correlation Coefficient was used for determining the relations between dependent and independent variables and descriptive statistics in analyzing datum. In addition to this, Multiple Linear Regression Analysis was used for investigating regression level between independent and dependent variables. As a result of this, middle blockers jumped the most (M=155.86, SD=39.77) while opposites jumped the least (M=73.31, SD=23.49). The amount of jumps of wing spikers (r= -.130, p<.05) and middle blockers (r= -.185, p<.01) was negatively related with team success at the end of the season in low level. The total amount of jumps in different positions was negatively related with team success at the end of the season in low level too (r= -.156, p<.01). Setters, wing spikers, middle blockers and opposites were listed with respect to regression factor (ß) and their importance level for team success at the end of the league. In conclusion, number of jumps in different positions at game time affects team success positively.

Published: September 2018

The important stage of breeding program for F1 hybrids with high yield capacity is to estimate the combining ability of parental lines for productivity characteristics. The information on combining ability may predict the productivity traits to exhibit and helps produce heterotic hybrids and use the initial breeding accessions in tomato. The combining ability of breeding accessions for yield traits was studied with the use of topcross crossing. According to the study of high yielding varieties, the varieties all increase the maturity of hybridisation. However, Jelty gigant varieties have the advantage of general and special combinations (gi = 15.6, σsi2 = 6.4), the minimum seedling duration, and the early varieties of varieties can be used for breeding varietiesThe combinations of our studies include the maturation of flowering and fruitful maturity of h2=0.69-0.67, fruit quantity per plant h2=0.60-0.66) by selection and those are inheritable characters with medium value. Early or total yield h2=0.45-0.58 leaf quantity until first inflorescences h2=0.27 had low heritage coefficient, respectively.

Authors: GASKA Piotr , GRUZA Maciej , HARMATYS Wiktor , GASKA Adam , SLADEK Jerzy
Published: September 2018

The measurements of solids of revolution are one of the most common task in industrial practice. Therefore it is not surprising, that new solutions dedicated to improve accuracy and acceleration of measurements of rotational components are emerging. In this group, the new generation of articulating probing systems (with ability of continuous indexation) is worth mentioning. These probing devices combined with standard CMM forms the five-axis coordinate system. Such solution results in measurements acceleration and also improve measurement repeatability. Studies on this type of probing systems proved that their accuracy depends strongly on the angular orientation of probing system used during measurement. Therefore authors developed model that allows simulation of probing system errors for any orientation. This article describes an attempt to use the model to find the configuration of the probing system that would provide the highest accuracy for rotational elements measurements. The simulation results are compared to the real measurements of standard elements performed on five axis measuring system. Described prediction method could have a beneficial effect on improving the accuracy of measurements and, as a result, on reducing production costs by minimizing the risk of erroneous decision on the conformity of products with their geometric specifications.
Strategy use on bounded and unbounded number lines in typically developing adults and adults with dyscalculia: An eye-tracking study
Authors: van der Weijden Fae Aimée , Kamphorst Erica , Willemsen Robin Hella , Kroesbergen Evelyn H. , van Hoogmoed Anne H.
Published: September 2018

Recent research suggests that bounded number line tasks, often used to measure number sense, measure proportion estimation instead of pure number estimation. The latter is thought to be measured in recently developed unbounded number line tasks. Children with dyscalculia use less mature strategies on unbounded number lines than typically developing children. In this qualitative study, we explored strategy use in bounded and unbounded number lines in adults with (N = 8) and without dyscalculia (N = 8). Our aim was to gain more detailed insights into strategy use. Differences in accuracy and strategy use between individuals with and without dyscalculia on both number lines may enhance our understanding of the underlying deficits in individuals with dyscalculia. We combined eye-tracking and Cued Retrospective Reporting (CRR) to identify strategies on a detailed level. Strategy use and performance were highly similar in adults with and without dyscalculia on both number lines, which implies that adults with dyscalculia may have partly overcome their deficits in number sense. New strategies and additional steps and tools used to solve number lines were identified, such as the use of the previous target number. We provide gaze patterns and descriptions of strategies that give important first insights into new strategies. These newly defined strategies give a more in-depth view on how individuals approach a number lines task, and these should be taken into account when studying number estimations, especially when using the unbounded number line.
Numerical cognition in action: Reaching behavior reveals numerical distance effects in 5- to 6-year-olds
Authors: Erb Christopher D. , Moher Jeff , Song Joo-Hyun , Sobel David M.
Published: September 2018

This study investigates how children’s numerical cognition is reflected in their unfolding actions. Five- and 6-year-olds (N = 34) completed a numerical comparison task by reaching to touch one of three rectangles arranged horizontally on a digital display. A number from 1 to 9 appeared in the center rectangle on each trial. Participants were instructed to touch the left rectangle for numbers 1-4, the center rectangle for 5, and the right rectangle for 6-9. Reach trajectories were more curved toward the center rectangle for numbers closer to 5 (e.g., 4) than numbers further from 5 (e.g., 1). This finding indicates that a tight coupling exists between numerical and spatial information in children’s cognition and action as early as the preschool years. In addition to shedding new light on the spatial representation of numbers during childhood, our results highlight the promise of incorporating measures of manual dynamics into developmental research.
Tracking the continuous dynamics of numerical processing: A brief review and editorial
Authors: Faulkenberry Thomas J. , Witte Matthias , Hartmann Matthias
Published: September 2018

Many recent studies in numerical cognition have moved beyond the use of purely chronometric techniques in favor of methods which track the continuous dynamics of numerical processing. Two examples of such techniques include eye tracking and hand tracking (or computer mouse tracking). To reflect this increased concentration on continuous methods, we have collected a group of 5 articles that utilize these techniques to answer some contemporary questions in numerical cognition. In this editorial, we discuss the two paradigms and provide a brief review of some of the work in numerical cognition that has profited from the use of these techniques. For both methods, we discuss the past research through the frameworks of single digit number processing, multidigit number processing, and mental arithmetic processing. We conclude with a discussion of the papers that have been contributed to this special section and point to some possible future directions for researchers interested in tracking the continuous dynamics of numerical processing.

Uden kulturpåvirkninger ville menneskelige samfund være forudsigelige. Nye teknologier er en af det allermest indgribende kulturpåvirkninger, der skaber forandring i menneskers liv. Nye teknologier ændrer vaner, værdier, handleviden og institutionsliv generelt. På trods af denne gennemgribende indflydelse på vores hverdagsliv er teknologiforståelse ikke noget, vi lærer om i skolen. Mange får heller ikke undervisning i det på deres videregående uddannelser. I denne artikel diskuterer jeg hvilken undervisning i teknologiforståelse, der er behov for, hvis fremtidens unge skal kunne håndtere udfordringer fra teknologiens kulturpåvirkninger.
Den spilkompetente lærer

Published: September 2018

På trods af den stigende udbredelse af computerspil i skolen findes der kun begrænset forskning, der konkret undersøger, hvad det kræver at bruge spil i undervisningen. Fokus for denne artikel er derfor at beskrive, hvad det vil sige at være en spilkompetent lærer. Det vil sige, hvordan man som lærer skal kunne udvælge, afprøve, spille, forstå, iscenesætte, facilitere og evaluere brugen af spil i undervisningen. Læreres spilkompetence kan beskrives som en kobling af to praksisformer, der dels handler om at udvise game literacy (“spilkyndighed”), dels handler om gamemastering, som er lærerens didaktiske evne til at kunne iscenesætte spilscenarier i undervisningen. Artiklen gennemgår en række empiriske eksempler på game literacy og gamemastering i forhold til brugen af komplekse computerspil som Minecraft og Torchlight II i undervisningen. Til sidst opsummerer vi didaktiskeprincipper for, hvad det kræver at være en spilkompetent underviser.

Своју стручност и умјешност на пољу методич-ких проучавања, провјеравану на научним скуповима, стручним семи-нарима и методичким радионицама, аутор је преточио у многобројнерадове од којих се шеснаест, по одабиру приређивача, нашло унутар ко-рица ове књиге. Ријеч је о књижевно-научним и наставним приступимаметодским јединицама из области књижевности које су заступљене унаставним програмима основних и средњих школа. М. Павловић се заи-ста на студиозан и креативан начин посветио проблематици наставекњижевности, посматрајући је са два врло важна аспекта: са аспектапредавача и са аспекта слушаоца, односно ученика. Застарјелим мето-дичким моделима, ригидним правилима и превазиђеној методичко-ди-дактичкој пракси, по ауторовом мишљењу, нема мјеста у савременомнаставном процесу.

У раду се указује на перифрастичке форме компарације, које су веомафреквентне у функционалним стиловима српског језика. Будући да је син-тетичка компарација затворен систем и да постоје случајеви када је нужноупотријебити аналитичке форме компарације, потребно је указати на так-ве језичке појаве, разјаснити конкурентске и комплементарне односе син-тетичких и перифрастичких форми компарације и указати бар на основнемоделе перифрастичке компарације.

Нарочито су у Србији наши шири кругови били дуго завараваниречима за њих сибилски неразговетним као што је илирство ијугославизам, а затим именима Штросмајера и Рачког, која сунајзад била постала символима и легендама, скоро светачким и пророч-ким. За словенску психу српског човека изгледало је на тај начин да јеоно што је мутно, било и дубоко. Васпитан у култу хероја из свог цар-ствујушћег средњег века, за њега су ова два католичка свештеника билисве занимљивији, што су били више несхватљиви. Обојица мало штонису из једне сумњиве историје и шарене литературе, пролазећи крозрежимски апарат наших дугогодишњих диктатура, значи кроз један зва-нични патриотизам, продрли и међу имена нашег највећег дохвата иостварења.
ТУХАФ ВИЛАЈЕТ. ПЕРЦЕПЦИЈА БОСНЕ И КУЛТУРАЛНА ИНТЕРАКЦИЈА У КЊИЖЕВНОМ ДЈЕЛУ ИВЕ АНДРИЋА

Аутор овога текста настојао је на једном мјесту анализирати главнинуоних елемената у опусу Иве Андрића који се на експлицитан начин тичу Боснеи људи у њој. На поетичком и значењском плану ови елементи чине значајанкорпус разнородних рефлексија чији је заједнички именилац перцепција Бо-сне, а у полифонији Андрићевих дјела у вези с тим издвајају се нарочито лико-ви странаца. Странац у Босни као фигура у Андрићевом опусу јавља се у вели-ком броју његових остварења, прије свега у романескном и приповједном кор-пусу, али исто тако и у другим дјелима овога писца. Андрићев странац критич-ки перципира Босну, изражава о њој аутентичан став и мишљење формирано уискуству непосредног сусрета с овом земљом и њеним људима. Критичка пер-цепција Босне у белетристичким остварењима Иве Андрића тематски је изазову стварању једне нарочите типологије, при чему је у његовом дјелу тежиштекритичког мишљења о Босни управо на ликовима. Методолошки приступ икритички аспект истраживања у основи су имаголошке и културолошке приро-де, будући да се једно од тежишних питања у Андрићевом опусу поставља и усвјетлу производње другости у најширем смислу, при чему је то друго, „вјечитострано” у Андрићевом дјелу, поприште и позорница културалне интеракцијеиз које ова проблематика и произилази – најчешће сама Босна.

О лику и дјелу највећег српског просвјетитеља, Светог Саве (1175–1235), и његовом пресудном утицају за конституисање српскогидентитета, говорило се од XIII вијека па све до данас. И поредове чињенице која у себи носи тежину осмовјековног постојања његовогкулта, многи Срби данас немају праву представу о духовном темељу на-ције, па тако о Светом Сави знају веома мало чињеница, што доводи доапстраховања његовог лика, или пак његовог доживљавања у контекстународних прича, које иако често поучне и поетизоване, не могу изрази-ти у потпуности суштину вјечитог духовног вођа српског народа.

Defective RNA polymerase III is negatively regulated by the SUMO-Ubiquitin-Cdc48 pathway
Authors: Wang Zheng , Wu Catherine , Aslanian Aaron , Yates John R , Hunter Tony
Published: September 2018

Transcription by RNA polymerase III (Pol III) is an essential cellular process, and mutations in Pol III can cause neurodegenerative disease in humans. However, in contrast to Pol II transcription, which has been extensively studied, the knowledge of how Pol III is regulated is very limited. We report here that in budding yeast, Saccharomyces cerevisiae, Pol III is negatively regulated by the Small Ubiquitin-like MOdifier (SUMO), an essential post-translational modification pathway. Besides sumoylation, Pol III is also targeted by ubiquitylation and the Cdc48/p97 segregase; these three processes likely act in a sequential manner and eventually lead to proteasomal degradation of Pol III subunits, thereby repressing Pol III transcription. This study not only uncovered a regulatory mechanism for Pol III, but also suggests that the SUMO and ubiquitin modification pathways and the Cdc48/p97 segregase can be potential therapeutic targets for Pol III-related human diseases.

The TP53 tumor-suppressor gene is mutated in >50% of human tumors and Li-Fraumeni patients with germ line inactivation are predisposed to developing cancer. Here, we generated tp53 deleted zebrafish that spontaneously develop malignant peripheral nerve-sheath tumors, angiosarcomas, germ cell tumors, and an aggressive Natural Killer cell-like leukemia for which no animal model has been developed. Because the tp53 deletion was generated in syngeneic zebrafish, engraftment of fluorescent-labeled tumors could be dynamically visualized over time. Importantly, engrafted tumors shared gene expression signatures with predicted cells of origin in human tissue. Finally, we showed that tp53del/del enhanced invasion and metastasis in kRASG12D-induced embryonal rhabdomyosarcoma (ERMS), but did not alter the overall frequency of cancer stem cells, suggesting novel pro-metastatic roles for TP53 loss-of-function in human muscle tumors. In summary, we have developed a Li-Fraumeni zebrafish model that is amenable to large-scale transplantation and direct visualization of tumor growth in live animals.

DE-ETIOLATED 1 (DET1) is an evolutionarily conserved component of the ubiquitination machinery that mediates the destabilization of key regulators of cell differentiation and proliferation in multicellular organisms. In this study, we provide evidence from Arabidopsis that DET1 is essential for the regulation of histone H2B monoubiquitination (H2Bub) over most genes by controlling the stability of a deubiquitination module (DUBm). In contrast with yeast and metazoan DUB modules that are associated with the large SAGA complex, the Arabidopsis DUBm only comprises three proteins (hereafter named SGF11, ENY2 and UBP22) and appears to act independently as a major H2Bub deubiquitinase activity. Our study further unveils that DET1-DDB1-Associated-1 (DDA1) protein interacts with SGF11 in vivo, linking the DET1 complex to light-dependent ubiquitin-mediated proteolytic degradation of the DUBm. Collectively, these findings uncover a signaling path controlling DUBm availability, potentially adjusting H2Bub turnover capacity to the cell transcriptional status.
