Published: February 2020

Abstract. In order to study the effect of different amounts of concentrate feed and the effectiveness of natural antioxidants on
the fatty acid stability of intramuscular fat during the first days postmortem, 75 young bulls of the Retinta breed were divided in three groups: 30 were grazed, 30 were fed on medium concentrate diets, and 15 were fed on high-concentrate diets. Young bulls were slaughtered at commercial weight, around a 500 kg final body weight. Samples from
Longissimus lumborum muscle were assigned to two ageing periods (0 and 7 d) and were vacuum packaged in
vacuum bags (O2 permeability: 9.3 mL O2/m2 per 24 h at 0 ∘C)
using an EGARVAC® sealer. Beef from grass-fed bulls showed a higher polyunsaturated fatty acid
content than concentrate-fed bulls. During the first 7 d postmortem, no changes in the fatty acids profile
were observed, because α-tocopherol content was optimal to prevent lipid oxidation. The higher level of natural
antioxidants in grass than in grain resulted in the stability of the fatty acid profile. This study shows that the
anti-oxidative potential of natural antioxidants in meat plays an important role during the first 7 d postmortem.
Ancillary services from wind turbines: automatic generation control (AGC) from a single Type 4 turbine
Authors: Rebello Eldrich , Watson David , Rodgers Marianne 
Published: February 2020

Abstract. Wind turbines possess the technical ability to provide various ancillary services to the electrical grid. Despite this, renewable generators such as wind and solar have traditionally not been allowed to provide significant amounts of ancillary services, in part due to the variable and uncertain nature of their electricity generation. Increasing levels of renewable generation, however, continue to displace existing synchronous generation and thus necessitate new sources of ancillary or system services. This work is part of an ongoing project that seeks to provide empirical evidence and an examination of how ancillary services can be provided from commercially available wind turbines. We focus specifically on providing secondary frequency response (automatic generation control or AGC) and demonstrate that wind turbines have the technical capability to provide this service. The algorithms used are intentionally simple so as to evaluate the capabilities and limitations of the turbine technology. This work presents results from a single, 800 kW, International Electrotechnical Commission (IEC) Type 4 wind turbine. A total of 10 % of rated power is offered on the regulation market. We do not separate up- and downregulation into individual services. Upregulation is offered through a 5 % constant power curtailment. The AGC update interval is 4 s, to mimic real-world conditions. We use performance scoring methods from the Pennsylvania–Jersey–Maryland (PJM) operator and the National Research Council (NRC) of Canada to quantify the wind turbine's response. We use the calculated performance scores, annual site wind data, and 2017 PJM market price data to estimate income from providing secondary frequency regulation. In all cases presented, income from the regulation market is greater than the energy income lost due to curtailment.
Nostalgia, distopia e ficção seriada: relações entre passado e futuro no imaginário contemporâneo
Authors: Machado Heitor Leal 
Published: February 2020

Este trabalho procura refletir sobre as noções de nostalgia e distopia em relação à ficção seriada televisiva. O objetivo é questionar a presença dos tempos passados e futuros nesse tipo de narrativa, produções transnacionais histórica e culturalmente localizadas que abordam os riscos, medos e anseios dos indivíduos na contemporaneidade. Assim, séries, minisséries e telenovelas abrem espaço para dar novos sentidos às experiências passadas e imaginar um futuro por vir. Um jogo em que o passado é positivado e compreendido como algo bom, mas que se perdeu, enquanto o futuro é desesperançoso e caótico, projetando o imaginário de um mundo em crise.
The Discovery of the Argyle Pipe, Western Australia: The World’s First Lamproite-Hosted Diamond Mine

Published: February 2020

Abstract
Argyle diamond mine discovery is a tale of scientific exploration, belief, and persistence over a nine-year period from project formulation in 1971 to pipe discovery in 1979. Initial inspiration came from a suggestion that leucite lamproites that crop out in the Kimberley region of Western Australia were derived by differentiation from a kimberlite-like peridotite magma. A 200,000-km2-wide program of reconnaissance stream sampling was initiated in the north of Western Australia and discovered kimberlite indicator minerals and diamonds in three parts of the Kimberley basin and adjacent King Leopold and Halls Creek orogens. An innovative laboratory was constructed for indicator mineral recovery, and the use of chromite as an indicator was pioneered and proved a key mineral. Follow-up of indicator/diamond anomalies led to the world’s first recognition of olivine lamproites. The program led to the discovery of the smaller-scale Ellendale lamproite diamond deposit en route to finding the tier 1, high-grade Argyle pipe, the world’s first economic olivine lamproite-hosted diamond deposit, which has produced &gt;750 million carats since 1983. Prior to these discoveries, traditional targets for diamond pipe exploration were areas of ancient cratonic basement. The Argyle and Ellendale deposits lie within the Halls Creek and King Leopold orogens, respectively, over thrust upon ancient cratonic lithosphere. The discoveries thus introduced a new target rock, olivine lamproite, for diamond exploration in nontraditional orogen environments.
Evaluation of the AK1 Deposit at Argyle Diamond Mine

Published: February 2020

Abstract
The 36-year evaluation history of the AK1 lamproite of the Argyle diamond mine (1980–2016) captures an important chapter in the development of diamond deposit evaluation. The resource potential was recognized early in the evaluation process, despite indications of a fine diamond size-frequency distribution and lower-quality stones. High diamond density and the size-frequency distribution characteristics allowed development of sampling methods. These included large-diameter core sampling and analysis of 20-kg samples of NQ/split HQ core for microdiamonds, which were significantly cheaper than traditional methods and unique to the diamond industry at the time. These methods permitted increasingly deep evaluation programs that augmented resources, underpinned the underground block cave feasibility study and, for the first time, revealed four coalescing vents of the AK1 orebody to –735 m reduced level.
The majority of the deposit has high to moderate grades (2–5 ct/t), with extremely high grades in the uppercentral parts (&gt;10 ct/t) and low grades in the north (0–1 ct/t). Despite some anomalous areas, at the scale of mining the AK1 deposit is striking in its size-frequency distribution homogeneity. Diamond size-quality distribution has also remained consistent for many years, being lower in the south and higher in the central-north with respect to the main central part of the deposit. The largest diamond deposit in the world (by contained diamond carats) and the largest producer, AK1 has sustained annual production averaging &gt;25 million carats per annum (more than twice its nearest competitor). Size, homogeneity, and high grades (average 3.5 ct/t over 36 years) have been crucial to its longevity and economic success.

Abstract
The Argyle (AK1) pipe in the Kimberley region of Western Australia is the world’s largest source of natural diamonds, and it has produced more than 835 million carats since mining began in 1983. The ~1.2 Ga olivine lamproite pipe lies within the Paleoproterozoic Halls Creek orogen at the southeastern margin of the Kimberley craton, and it was emplaced during a period of extension associated with large-scale, NNE-trending strike-slip faulting of the orogen.
AK1 is composed of four coalesced, steep-sided diatremes aligned along an NNE-trending fault and tapering to narrow feeder zones at depth. The body is infilled by volcaniclastic olivine lamproite and cut by late olivine lamproite dikes. Two distinct groups of volcaniclastic rocks are present. The dominant type comprises mainly quartz-rich lapilli tuffs and coarse ash tuffs formed by numerous phreatomagmatic eruptions, when olivine lamproite magma was erupted through water-rich sands and silts of the Carr Boyd Group. In contrast, late-stage olivine lamproite lapilli tuffs, devoid of accidental quartz grains, fill the center of the northern diatreme.
Following emplacement, the body was tilted 30° to the north and extended north-south by the sinistral north-northwest–south-southeast Gap fault system and east-northeast–west-southwest by the dextral Razor Ridge fault. The Razor Ridge fault offsets the most southerly diatreme (southern tail) from the main part of AK1. Reversal of structural offsets affecting AK1 reveals a geometry which closely resembles that of other ultramafic diatremes.
Variations in diamond grade and quality within AK1 indicate that at least two distinct magmas with unique diamond contents have been emplaced at Argyle.

Introduction:The number of female residents in orthopaedic surgery is rising; however, orthopaedics currently has the lowest percentage of women among all medical specialties. The Hirsch index (h-index) is a metric used to determine research productivity, an important factor for academic promotion in the field of orthopaedics. The purpose of this study was to compare research productivity (using the h-index) among male and female orthopaedic surgeons at academic residency programs within the United States.Methods:The websites for all Accreditation Council for Graduate Medical Education-accredited orthopaedic surgery residency programs in the United States were evaluated and the following information was collected: geographic region of the institution, sex, specialty, academic rank, and institutional leadership positions of faculty members. The h-index for each faculty member was collected from the Web of Science Database.Results:H-indices of 4,323 academic orthopaedic surgeons from 160 residency programs in the United States were collected. In total, 1,587 faculty members were assistant professors (220, 13.9% women), 839 were associate professors (91, 10.8% women), 902 were professors (50, 5.5% women), and academic rank was not specified for 991 (74, 7.5% women). One hundred forty-three faculty members held the position of department chair (2, 1.4% women) and 701 were division chiefs (58, 8.3% women). In geographic regions with a greater proportion of female orthopaedic faculty members, women had greater research productivity. Among Department Chairs, associate professors, and professors there was no difference in research productivity between male and female academic orthopaedic surgeons. By contrast, among assistant professors, there was a significant difference in research productivity.Conclusion:A higher proportion of female faculty in an orthopaedic department was positively associated with increased female research productivity. Female faculty at the highest ranks and leadership positions are as academically productive as their male counterparts. Despite similar research productivity, female orthopaedic surgeons are not nearly as well represented as their male counterparts in orthopaedics in general and in leadership positions within the field. In addition, a significantly smaller research productivity among female assistant professors disappears at the higher ranks in comparison to their male counterparts. This indicates a critical gap in factors that influence research productivity according to sex at the most junior faculty rank.Level of Evidence:Level III

From tinkering with the system to building substantive renewal
This article analyzes the decentralization and transformation of Dutch youth care since 2015. The authors point out that many problems still exist and in some cases have become worse. To fundamentally reform youth care much more is needed than just money or a system change. It is necessary, also according to international research, to create a strong pedagogical basis or ‘pedagogical civil society’. Also prevention on various levels (universal, selective, indicated) should receive a lot of attention, while the same applies to improving primary care support, such as youth health care, GP practice support, youth work and school social work. It would also be wise to invest in intensive youth care with long-lasting effects. Generally there should be a strong focus on tackling local and (supra)regional social issues.

Taking care of unaccompanied minor immigrants
Among the asylum seekers arriving in Europe are unaccompanied minors (UMAs). As a result of the often traumatic experiences before and during their flight, many have mental health problems. The question is how they cope in the country of destination. After the flight, the plight is not over: destination countries are often not welcoming in all respects, UMAs may encounter violence in reception facilities, and experience stress related to the asylum procedure and possible family reunification, as well as worries about relatives left behind. Although UMAs are also known to be resilient, and most are supported by family members and/or significant others, there are worries about their transition to adulthood. When they turn 18, they have to deal with the developmental tasks that come with that age, as well as to come to terms with past experiences. At the same time their guardianship ends, and they are supposed to manage on their own in the relatively new country. Many UMAs seem to manage, but it would be helpful if the 18 years age limit could be used flexible when necessary.
Where Are the Women? Updating the Account!

Published: February 2020

Cet article met à jour les résultats analysés dans « A Tale of Three Women : The Visual Arts in Canada / A Current Account/ing » (RACAR, vol. XXV, no 1–2 (1998), p. 103–22, paru en 2001) et propose un état de la situation actuelle des femmes artistes au Canada. Il réexamine le caractère institutionnel de la discrimination et son impact dans les institutions postsecondaires et les musées, ainsi qu’en rapport au soutien apporté aux artistes individuels. Il actualise et élargit l’étude précédente d’un point de vue tant qualitatif que quantitatif. Les analyses qualitatives révisées des carrières de Kathleen Munn, Joyce Wieland et Vera Frenkel contrebalancent l’accent mis sur la comptabilisation. La recherche menée indique que les femmes, jusqu’alors sous-représentées, ont atteint la parité ou la quasi-parité des postes supérieurs et à plein-temps dans les départements universitaires d’arts plastiques considérés. De même, dans les concours pour les subventions de projets octroyées par le Conseil des arts du Canada, hommes et femmes artistes ont plus ou moins le même taux de succès. Toutefois, pour les allocations de subventions à long terme (qui ont une plus grande valeur monétaire) et de prix nationaux, le fossé entre les sexes demeure considérable. Si le Musée des beaux-arts du Canada semble avoir utilisé son pouvoir d’achat pour réduire, dans ses acquisitions, le déséquilibre entre les sexes, les oeuvres d’art qu’il expose et acquiert demeurent principalement créées par des hommes. Quoique l’analyse des bourses octroyées par le programme du Conseil des arts de Subventions d’acquisition aux musées et aux galeries d’art — qui offre un regard sur les pratiques de collection d’art contemporain au Canada — révèle une situation plus encourageante, il demeure qu’une hiérarchie genrée persiste dans la valeur des oeuvres acquises. Cet article insiste sur l’importance de comptabiliser et de dresser des bilans afin de prendre conscience de la situation, ainsi que sur la nécessité de rester vigilant pour remédier à l’inégalité entre les sexes.
Pierre Soulages’s Ultrablack Paintings: The Matter of Presence
Authors: Chakrabarty Ananda Shankar 
Published: February 2020

Pour la philosophe française Éliane Escoubas, l’« outrenoir » que l’artiste français Pierre Soulages a créé depuis 1979 démontre la « présence de la peinture en peinture. » Si la peinture outrenoire résulte d’un processus illustrant parfaitement la matérialité qui a fortement marqué une grande partie de l’art européen d’après-guerre, l’élément le plus remarquable des travaux outrenoirs de Soulages réside dans le spectacle de la tension lumineuse induite par les stries inscrites dans le pigment épais de ces peintures. S’appuyant sur une lecture approfondie des tableaux outrenoirs de Soulages, ainsi que sur plusieurs commentaires critiques d’historiens de l’art, cet article avance l’idée que le regardeur, tour à tour confronté aux effacements et aux dévoilements de la matière pigmentaire sur la surface de la peintre outrenoire, vit ici une expérience sensorielle. En rendant présent ce qui est détenu dans les plis, le spectacle de la peinture outrenoire offre la présence de la matière en tant que voir.
Annibale Carracci and the Modern Reform of Altar Painting
Authors: Stoenescu Livia 
Published: February 2020

Annibale Carracci constitue un objet d’autant plus intéressant à étudier que sa carrière va à l’encontre des conventions et des normes de la Contre-Réforme et de l’art baroque. Les qualités éclatantes de ses oeuvres nous forcent à revoir les notions de décadence et de crispation habituellement associées à la Contre-Réforme en même temps qu’elles évitent les excès typiques des peintures de commande de la période baroque réalisées sur commande que la Réforme jugera par trop « démonstratives ». Annibale Carracci a permis à la peinture de progresser d’un bond en poussant plus loin les réalisations de ses prédécesseurs de la Renaissance tout en faisant le tri des idées fortes ou des contraintes pratiques qui régissaient leurs créations. À bien des égards, il faut cependant rappeler que cette perception s’explique moins par le désir d’éclairer son programme de réforme que par le besoin de faire correspondre Annibale à la dimension grandiose du Baroque et à l’esprit rigoriste de la Contre-Réforme. Les commentaires d’historiographes tels que Malvasia et Bellori, qui avaient tenté de sortir Annibale de la déplorable réputation que lui avait faite Baglione—qui était pour la Contre-Réforme—ont poussé plus d’un auteur à interpréter son recours aux motifs classiques comme le parfait exutoire d’une passion baroque. De telles exagérations entretenues par Donald Posner, S.J. Freedberg et Charles Dempsey sont imprégnées de l’idée que l’Antiquité classique a joué un rôle prédominant dans l’art baroque. Mais les recherches ne se sont jamais penchées sur les raisons pour lesquelles Annibale Carracci est un réformateur. Consciente des pièges que représentent les normes et les classifications, mon étude se fonde sur l’idée que le programme réformateur de Annibale réside dans de nouvelles modalités de l’art narratif et dans les changements drastiques apportés aux conventions et aux traditions de la peinture d’autel. Sa fameuse Crucifixion peinte en 1583 et toujours visible dans l’église Sta. Maria delle Carità à Bologne offre une illustration convaincante de la réforme telle qu’Annibale Carracci la concevait.
Publier sur la Révolution américaine en France (1778-1788)
Authors: Lounissi Carine 
Published: February 2020

Cet article propose une étude des conditions de rédaction et de publication des ouvrages écrits en français sur la Révolution américaine pendant les années 1780. Ce corpus, négligé jusqu’à présent par les historiens, comprend des textes soumis pour révision aux diplomates américains en poste en Europe. Or, ces collaborations relativement peu étudiées permettent de réévaluer ce moment franco-américain. Il en est de même des Archives de la Librairie française qui contiennent les rapports des censeurs sur ces ouvrages, dont la plupart ont bénéficié d’une permission tacite pour circuler en France. Il ressort de la consultation de ces documents que les critiques à l’encontre des institutions françaises ont été secondaires pour Vergennes, à condition qu’elles ne fussent pas érigées en système théorique. Ces sources suggèrent que ces écrits sur la Révolution américaine ne peuvent plus être considérés uniquement en termes de « propagande », comme le faisait Durand Echeverria, mais méritent d’être intégrés à une histoire intellectuelle atlantique ou transatlantique de l’ère des révolutions.
Béranger in Nineteenth-Century America
Authors: Steele Robert O. 
Published: February 2020

Pierre-Jean de Béranger (1780–1857) was revered during his lifetime as the national poet of France. His championing of the Revolution and the people earned him significant impact in the United States; an antebellum American reviewer touted Béranger’s patriotism and his struggle for liberty as a model for an American national poetry. Translations of his songs were published in various formats at various prices by major publishers who also imported French-language editions. Translators struggled to bring his politically radical and sexually scandalous texts across linguistic and cultural borders to construct a Béranger who could be understood in the United States. Yet by refusing to translate Béranger, direct-language pioneer Lambert Sauveur subversively exposed his students to the Christian roots of socialism and a defense of the Paris Commune. By century’s end, Béranger’s influence had faded to mere inclusion in delicately suggestive anthologies, but his voice lived on to inspire leftists of the next century.
Les enjeux d’une professionnalisation axée sur le « spirituel »
Authors: Cherblanc Jacques , Risdon Marie-Anne 
Published: February 2020

Le service d’animation spirituelle et d’engagement communautaire existe depuis 2001. Il remplace l’animation pastorale scolaire et a pour but de favoriser le développement spirituel et l’engagement communautaire de chaque élève, quelle que soit son appartenance ou non à une confession religieuse. Cet article présente l’historique ayant conduit à l’élaboration de ce service ainsi que les interrogations professionnelles actuelles de ses intervenants. Ces interrogations sont basées sur une prise de conscience de la grande diversité des personnes qui offrent ce service, diversité dans leur formation, mais aussi dans leur compréhension du sens des termes définissant leur travail. Oeuvrant aujourd’hui à une professionnalisation qu’ils jugent essentielle à leur survie même, ils utilisent des stratégies professionnelles qui apparaissent toutefois peu conformes à leur réalité et à leur pouvoir. Cet article souhaite montrer la pertinence de changer de perspective soit de ne plus concevoir leur profession à partir des paradigmes fonctionnalistes ou conflictualistes, ni de l’ancrer dans le volet « engagement communautaire », mais plutôt d’adopter un point de vue interactionniste, et que celui-ci soit axé autour du volet « spirituel ».
