Vegetation Influence and Environmental Controls on Greenhouse Gas Fluxes from a Drained Thermokarst Lake in the Western Canadian Arctic
Authors: Skeeter June , Christen Andreas , Laforce Andrée-Anne , Humphreys Elyn , Henry Greg
Published: February 2020

Abstract. Thermokarst features are widespread in ice-rich regions of the circumpolar Arctic. The rate of thermokarst lake formation and drainage is anticipated to accelerate as the climate warms. However, it is uncertain how these dynamic features impact the terrestrial Arctic carbon cycle. Methane (CH4) and carbon dioxide (CO2) fluxes were measured during peak growing season using eddy covariance and chambers at Illisarvik, a 0.16 km2 thermokarst lake basin that was experimentally drained in 1978 on Richards Island, Northwest Territories, Canada. Vegetation in the basin differs markedly from the surrounding dwarf-shrub tundra and included patches of tall shrubs, grasses and sedges with some bare ground and a small pond in the centre. During the study period, temperature and wind conditions were highly variable and soil water content decreased steadily. Basin scaled net ecosystem exchange (NEE) measured by eddy covariance was −1.5 [CI95 % ± 0.2] g C-CO2 m−2 d−1; NEE followed a marked diurnal pattern with no trend during the study period. NEE was primary controlled by photosynthetic photon flux density and influenced by vapor pressure deficit, volumetric water content and the presence of shrubs. By contrast, net methane exchange (NME) was low (8.7 [CI95 % ± 0.4] mg CH4 m−2 d−1 and had little impact on the carbon balance of the basin during the study period. NME displayed high spatial variability, sedge areas in the basin were the strongest source of CH4 while upland areas outside the basin were a net sink. Soil moisture and temperature were the main environmental factors influencing NME, having a positive and negative effect respectively.

Abstract. In this paper, we quantify CO2 and N2O emissions from denitrification over the Amazonian wetlands. The study concerns the entire Amazonian wetland ecosystem with a specific focus on three focal locations: the Branco Floodplain, the Madeira Floodplain and the floodplains alongside the Amazon River. We adapted a simple denitrification model to the case of tropical wetlands and forced it by open water surface extent products from the Soil Moisture and Ocean Salinity (SMOS) satellite. A priori model parameters were provided by in situ observations and gauging stations from the HyBAm observatory. Our results show that the denitrification and emissions present a strong cyclic pattern linked to the inundation processes that can be divided into three distinct phases: activation – stabilization – deactivation. We quantify the average yearly denitrification and associated emissions of CO2 and N2O over the entire watershed at 17.8 kgN/ha/yr, 0.37 gC/m2/yr and 0.18 gN/m2/yr respectively. When compared to local observations, it was found that the CO2 emissions accounted for 0.01 % of the integrated ecosystem, which emphasis the fact that minor changes to the land cover may induce strong impacts to the Amazonian carbon budget. Our results are quite consistent with the state of the art global nitrogen models with a positive bias of 28 %. When compared to other wetlands in different pedo-climatic environments we found that the Amazonian wetlands have close emissions of N2O to the tropical Congo wetlands and lower emissions than the tropical and temperate anthropogenic wetlands of the Garonne river, the Rhine river, and south-eastern Asia rice paddies. In summary our paper shows that a data driven approach can be successfully applied to quantify N2O and CO2 fluxes associated with denitrification over the Amazon basin. In the future, the use of higher resolution remote sensing product from sensor fusion or new sensors like the SWOT mission will permit the transposition to other large scale watersheds in tropical environment.
Systemic hazard analysis of offshore service operations
Authors: Puisa Romanas , Bolbot Victor , Newman Andrew , Vassalos Dracos
Published: February 2020

Abstract. As windfarms are moving further offshore, logistical concepts increasingly include service operation vessels (SOV) as the prime means of service delivery. However, given the complexity of SOV operations in hostile environments, their safety management is challenging. The objective of this paper is to bring awareness of hazards that may have been overlooked in earlier assessments, and allow for a preliminary comparison of various operational stages. To this end, we use a systems approach to identify and analyse hazards arising during the SOV transit and manoeuvre within a windfarm and interfaces with turbines and daughter crafts. The hazard analysis is performed by systemic method STPA, allowing to explore hazardous scenarios caused by flawed interactions between system components and, to a lesser extent, by component failures. The results comprise 23 operational hazards arising during the three stages of SOV operation and 1270 hazardous scenarios (pathways) leading to the hazards. The preliminary comparison of SOV operations shows that approaching and departing from turbines in auto and manual modes is potentially the riskiest stage of SOV operation. The lowest risk is of the SOV interface with daughter crafts. The paper discusses the analysis results and explains how they can be used to inform new and existing safety management systems of SOV.
Accurate loads and velocities on low solidity wind turbines using an improved Blade Element Momentum model
Authors: Ouakki Yassine , Arbaoui Abdelaziz
Published: February 2020

Abstract. The accurate prediction of loadings and velocities on a wind turbine blades is essential for the design and optimization of wind turbines rotors. However, the classical BEM still suffer from an inaccurate prediction of induced velocities and loadings, even if the classical correction like stall delay effect and tip loss correction are used. For low solidity rotors, the loadings are generally over-predicted in the tip region, since the far wake expansion is not accurately accounted for in the one-dimensional (1D) momentum theory. The 1D dimensional momentum theory supposes that the far wake axial induction is equal to twice the axial induction in the rotor plane, which results in an under-estimation of the axial induction factor in the tip region. Considering the complex nature of the flow around a rotating blade, the accurate estimation of 3D effects is still challenging, since most stall delay models still often tend to under-predict or over-predict the loadings near the root region. As for the solution method for the classical BEM equation, the induced velocities are computed accounting for the drag force. However, according to the Kutta-Joukowski theorem, the induced velocities on a blade element are only created by lift force. Accounting for drag force when solving the BEM will result in an over-estimation of the axial induction factor, while the tangential induction factor is under-estimated. To improve the accuracy of the BEM method, in this paper, the 1D momentum theory is corrected using a new far wake expansion model to take into account the radial flow effect. The blade element theory is corrected for three-dimensional effects through an improved stall delay model. An improved solution method for the BEM equations respecting the Kutta-Joukowski theorem is proposed. The improved BEM model is used to estimate the aerodynamic loads and velocities on the National Renewable Energy Laboratory Phase VI rotor blades. The results of this study show that the proposed BEM model gives an accurate prediction of the loads and velocities compared to the classical BEM model.
Variações do mito da Ilíada: Da intercessão divina ao abandono dos mortais
Authors: De Carli Anelise Angeli
Published: February 2020

Neste artigo, são comparadas duas formas de apresentação do mito da Ilíada: no romance épico de Homero e no filme Troy. São utilizadas as definições de sagrado e de mito de Mircea Eliade e da derivação do mito em Gilbert Durand para elaborar uma leitura simbólica comparativa. O objetivo é tirar consequências para o sentido do mito através da descrição das cenas no cinema contemporâneo e na literatura arcaica. Conclui-se que o apagamento dos deuses como personagens amplifica a esfera de ação dos homens, ao mesmo tempo em que inviabiliza o ensinamento de modelos exemplares e deixa a humanidade abandonada a seus melhores instintos, os sentimentos nobres e moralmente aceitos em determinado momento histórico.

O presente trabalho apresenta notas sobre a origem e a consolidação do folhetim como uma seção localizada na extremidade inferior dos jornais franceses. Além disso, levanta-se a constituição do romance-folhetim como uma matriz de linguagem, indicando suas fases e avaliando a construção de seus ganchos. Há uma análise narrativa seguindo Propp (2012) e Mckee (2006) do gancho do primeiro capítulo do romance-folhetim A Condessa de Salisbury (1836), escrito por Alexandre Dumas. Da alteração do tamanho da folha do papel às experimentações no espaço extra, o termo “folhetim” tornou-se sinônimo de apenas uma de suas publicações, o romance-folhetim, ainda que tenha sido um espaço de textos diversos.

Nature of the Mantle Beneath the Argyle AK1 Lamproite Pipe: Constraints from Mantle Xenoliths, Diamonds, and Lamproite Geochemistry
Authors: Jaques A. L. , Luguet A. , Smith C. B. , Pearson D. G. , Yaxley G. M. , Kobussen A. F.
Published: February 2020

The richly diamondiferous ~1180 Ma Argyle AK1 lamproite pipe at the margin of the Kimberley craton of Western Australia is underlain by a depleted Archean lithospheric root composed mostly of garnet-poor lherzolite. Peridotite xenoliths (some diamondiferous) define a cratonic paleogeotherm with a ~200-km-thick lithosphere, comparable with estimates from present-day seismic S-wave tomography. The Argyle lamproite is highly enriched in incompatible elements and formed by very small degrees of partial melting under reduced H2O- and HF-rich conditions of depleted lithospheric mantle that had undergone long-term (>2 Ga) geochemical enrichment. Multiple metasomatic and thermal events including episodic formation of diamond have impacted on the lithosphere of the Kimberley craton, both predating and postdating Paleoproterozoic reworking of its margins and amalgamation within the larger North Australian craton. At Argyle, the inventory of older (Archean?) peridotitic diamonds in the craton root was augmented by Proterozoic (1.58 Ga) eclogitic diamonds with distinctive light carbon isotope compositions to generate Argyle’s rich diamond grades.

The Argyle lamproite and other brief episodes of kimberlite, lamprophyre, and lamproite magmatism (some diamondiferous) on the Kimberley craton all bear their own geochemical and isotopic signature, reflecting variable relative contributions from asthenospheric and enriched lithospheric mantle sources. Mantle melting and eruption of small volumes of these diverse magmas may have been triggered by small short-lived thermal perturbations from the asthenosphere and/or tectonic events elsewhere on the Australian continent, triggered by global plate reconfiguration.
The Unique Nature of Argyle Fancy Diamonds: Internal Structure, Paragenesis, and Reasons for Color

Published: February 2020

The Argyle lamproite mine is world famous for fancy colored diamonds, ranging from cognac and champagne shades of brown through Cape yellows to rare pink to intense red and even rarer blue stones. The majority of diamonds are type IaAB, displaying platelet degradation and having plastic and brittle deformation, mainly after diamond formation, indicative of high pressure/temperature conditions. The deformation produced optical defects, causing different Argyle diamond colors.

White and brown Argyle diamonds belong to both eclogitic and peridotitic parageneses, but yellow- and pink-colored ones studied here are eclogitic. Nitrogen contents, N aggregation states, and formation temperatures of yellow diamonds are correlated with their internal structure. The strongly deformed and internally brecciated yellow diamonds have low to moderate contents of highly aggregated N and high temperatures of formation. The undeformed yellow diamonds are richer in moderately aggregated N, and their formation temperatures are lower. The intensity of N3, H3, and H4 bands of the photoluminescence spectra of these diamonds is higher in the more deformed crystals.

The pink eclogitic diamonds contain low to moderate N, are highly aggregated, and have high temperatures of formation, but differ from each other in the deformation level recorded by their internal structures. All identified photoluminescence peaks in these pink diamonds are higher in intensity in the strongly deformed crystals.

Geothermometry, based on N contents, aggregation state, age, and temperature relationships of the diamonds, shows that most eclogitic diamonds resided at 1,250° to 1,300°C near the base of the lithospheric mantle, slightly deeper than the peridotitic diamonds. One eclogitic pink diamond contains a two-phase garnetomphacite inclusion reequilibrated from precursor majorite with composition indicative of formation pressure of 9.5 to 10 GPa, equivalent to ~300-km depth, the deepest identified for Argyle diamond formation to date. Internal structures of eclogitic diamonds reflect evidence of their formation under stress in a subduction zone setting.

Published: February 2020

The diamonds sourced from the Mesoproterozoic Atri pipe are white to brown in color and often plastically deformed, with two morphological populations present, octahedra dominant in the finer sizes, and resorbed dodecahedra in the coarser sizes. The color and resorbed shapes have some resemblance to properties of diamonds from the Majhgawan lamproite 80 km to the east-northeast and of the brown, plastically deformed diamonds from the Mesoproterozoic Argyle lamproite pipe in Australia. The diamond infrared spectra indicate low to moderate nitrogen content and IaA to IaAB aggregation and show occasional spikes related to hydrogen and carbonate presence, which suggests diamond formation through cooling of hydrous fluids that contain both CH4 and CO2. Platelet peaks are commonly prominent and show regular correlation with the IaB component, unlike the irregular diamonds from Argyle. The diamond inclusions are dominantly peridotitic olivine and Cr-rich magnesiochromite formed from depleted lithospheric mantle at ~150-km depth at an estimated 1,140° to 1,200°C, corresponding to a typical cratonic geotherm equivalent to 40-mW/m2 model surface heat flow. The predominance of harzburgitic-type inclusions and the lack of eclogitic-type indicators in the heavy mineral concentrates suggest that both the diamonds and mantle section sampled by the Atri intrusion are mainly or entirely peridotitic in nature, unlike those of the Argyle lamproite, despite their similar craton-marginal tectonic positions.
Intensifiers, Reflexive and Reciprocal Pronouns in Argobba Language, Ethio-Semitic
Authors: Awol Ousman Shafi
Published: February 2020

Argobba is a South Ethio-Semitic language which is predominantly used in day-to-day communication by a population of about 140, 134 people in the Argobba Zone (Central Statistical Agency (2008:59), Ethiopia, whose linguistic features were not well described. The Argobba lives in the escarpment slopes of northeastern Shewa and southeastern Wollo, a minority of them are live in the adjoining settlements of the town of Harar in eastern Ethiopia.The Argobba make their living by cultivating plants, by breeding animals, weaving and by trade (Hussein, 2006:416). Most of the Argobba people are followers of Islam. As a result, the Islamic religion greatly influences the culture as well as the living style of the society. The central aim of this paper is to provide a comprehensive description and features of Intensifiers, reflexive and reciprocal pronouns of the Argobba language. The paper is descriptive in natureonly in Argobba language not comparing with other languages, since the study is mainly concerned with describing what is actually being in, and mainly relies on primary linguistic data. The linguistic data, i.e. the elicited grammatical data concerning Intensifiers, reflexive and reciprocal pronouns, was collected from native speakers of the language during 6 months of fieldwork conducted between 2015 and 2016 in five Kebeles and the administrative center of the Argobba. Intensifiers in Argobbaare derived from the noun ‘self’, which has the meaning ‘self’ as intensifier, or its reduplicated form ‘self with self’. Reflexive pronouns are formed by combining ‘self’ with the possessive suffixes while reciprocal pronouns can be formed through a construction consisting of the comitative morpheme, which intersects between the reduplicated noun ‘self’, and the plural possessive suffixes.

Published: February 2020

Introduction:

Proximal humerus fractures (PHF) are a common upper extremity fracture in the elderly cohort. An aging and more comorbid cohort, along with recent trends of increased operative intervention, suggests that there could be an increase in resource utilization caring for these patients. We sought to quantify these trends and quantify the impact that comorbidity burden has on resource utilization.

Methods:

Data on 83,975 patients with PHFs were included from the Premier Healthcare Claims database (2006 to 2016) and stratified by Deyo-Charlson index. Multivariable models assessed associations between Deyo-Charlson comorbidities and resource utilization (length and cost of hospitalization, and opioid utilization in oral morphine equivalents [OME]) for five treatment modalities: (1) open reduction internal fixation (ORIF), (2) closed reduction internal fixation (CRIF), (3) hemiarthroplasty, (4) reverse total shoulder arthroplasty, and (5) nonsurgical treatment (NST). We report a percentage change in resource utilization associated with an increasing comorbidity burden.

Results:

Overall distribution of treatment modalities was (proportion in percent/median length of stay/cost/opioid utilization): ORIF (19.1%/2 days/$11,183/210 OME), CRIF (1.1%/4 days/$11,139/220 OME), hemiarthroplasty (10.7%/3 days/$17,255/275 OME), reverse total shoulder arthroplasty (6.4%/3 days/$21,486/230 OME), and NST (62.7%/0 days/$1,269/30 OME). Patients with an increased comorbidity burden showed a pattern of (1) more pronounced relative increases in length of stay among those treated operatively (65.0% for patients with a Deyo-Charlson index >2), whereas (2) increases in cost of hospitalization (60.1%) and opioid utilization (37.0%) were more pronounced in the NST group.

Discussion:

In patients with PHFs, increased comorbidity burden coincides with substantial increases in resource utilization in patients receiving surgical and NSTs. Combined with known increases in operative intervention, trends in increased comorbidity burden may have profound effects on the cohort level and resource utilization for those with PHFs, especially because the use of bundled payment strategies for fractures increases.

Rapid Versus Standard Recovery Protocol Is Associated With Improved Recovery of Range of Motion 12 Weeks After Total Knee Arthroplasty
Authors: Plessl Daniel , Salomon Brett , Haydel Adam , Leonardi Claudia , Bronstone Amy , Dasa Vinod
Published: February 2020

Introduction:

With the increasing demand for total knee arthroplasty (TKA), rapid recovery protocols (RRPs) have been introduced to reduce costs and the length of stay (LOS). Little is known about the effects of RRPs on postoperative knee range of motion (ROM).

Methods:

We reviewed the medical charts of 323 patients who underwent primary TKA performed by a single orthopaedic surgeon at a university-based orthopaedic tertiary care safety net practice. Of the 323 patients, 129 were treated with a standard recovery protocol (SRP) between January 1, 2012, and December 10, 2013, and 194 with a RRP beginning December 11, 2013. Knee ROM was assessed at the preoperative visit and at scheduled postoperative visits for up to 1 year. Differences in mean LOS between the groups were compared using a Poisson regression with and without adjustment for covariates. Repeated measures analysis of covariance was used to evaluate the effects of recovery protocol, time, and the interaction of recovery protocol by time on flexion and flexion contracture. The probability of achieving flexion ≥120° and having a flexion contracture ≥10° was estimated using the SAS/STAT GLIMMIX procedure with a binary distribution and a logit link.

Results:

The mean LOS for the RRP and SRP groups was 0.8 and 2.5 days, respectively. RRP was associated with greater flexion at 2, 6, and 12 weeks and a higher probability of attaining flexion ≥120° at 6 and 12 weeks. Patients receiving a RRP had less severe flexion contracture and a lower probability of flexion contracture ≥10° at 2, 6, and 12 weeks.

Discussion:

During the first 12 weeks after TKA, patients who received a RRP had a markedly greater ROM than patients who received a SRP, suggesting that RRP may allow patients to do a greater variety of activities of daily living during the first 3 postoperative months while reducing health care costs.

LET US WALK THE TALK: THE RIGHT TO SOCIAL SECURITY AND SOCIAL PROTECTION – THE CASE FOR A NEW INTERNATIONAL CONVENTION
Authors: Cichon Michael
Published: February 2020

This paper focuses on the actions of the ILO towards Global South, with Brazil as a focal point. As the International Labour Organization has changed its paradigm during one hundred years of existence, the policies toward Global The human right to social security entered into international law in the middle of the last century. In 2012 the International Labour Conference took the latest step towards the concretisation of this right when it adopted its recommendation No. 202 (R202) concerning national fl oors of social protection. Shortly thereafter, in 2015, the global community of nations adopted the Sustainable Development Goals (SDG) which contain a comprehensive social protection agenda. Together, these two instruments set clear global objectives of social protection accessible to all people. It is argued here that the ILO or the UN have to take the next step and transform “soft” instruments of recommendation and goals into “hard” ones and develop a new convention on universal access to at least fl oor of social protection to a create true safeguard for the right to social security and make it more diffi cult to reverse achieved social progress.
Opening space at school for creative activity based on music
Authors: Stachyra Krzysztof , Łucjan-Kowalska Anita
Published: February 2020

The aim of the article is to analyse the ways of using creative music-based activities in the educational process. The authors emphasize the marginal role that art plays in contemporary school, including music. At the same time, they emphasize the need to change this state of affairs, convincing about the huge, unused potential of using music-based activities to build relationships, improve mood, develop creativity and emotional and social competence. The use of musical activities on educational grounds may go beyond the typical activities known from music lessons. Building space for experiencing creative forms of contact with art, expression, spontaneous singing or improvisation, enabling multi-sensory art experience, can result in measurable benefits for both students and the teacher, being the answer to the challenges of modern education. An additional benefit of conducting such classes is the opportunity to observe the functioning of students, ways of coping with social situations, and assumed roles in the group.
The article presents practical examples of the implementation of musical activities under the “ZA PROGIEM – wyprawy odkrywców project. The reactions of children participating in these activities testify to their great commitment, they also show that properly selected musical activities can have a positive impact on the child's behaviour in a very short time.
Conclusions from the implementation of the activities under the project indicate that music-based – or more broadly art-based – activities, present so far, in the presented form, in pedagogy to a very limited extent, may prove to be an effective tool to support teachers’ work and student development.
“ZA PROGIEM”. Educational values of children's learning outdoors
Authors: Andrzejewska Jolanta
Published: February 2020

The article presents the “ZA PROGIEM” – wyprawy odkrywców educational project implemented from August 2018 to July 2019 at the Institute of Pedagogy of the Maria Curie-Skłodowska University in Lublin. The project was to develop key competences of students through development and teaching tasks implemented in four-person peer groups. The project consisted of two six-hour cycles of educational tasks: “Present, past and future of the tree” and “Scent trackers”. Problem-based tasks were carried out in various educational areas, in diverse natural, social and cultural contexts. The beneficiaries of the workshops were students of grades I–III, in 8 groups (7 from the rural environment, 1 from the urban environment), each consisting of 12 people. The research used the participant observation method and the document analysis method. The project confirmed that environmental education conducted outdoors is an important element of upbringing, increases children's perceptiveness and creates emotional connection to the nature.

Marronage is Resistance Against the Colonizer’s Construction of History
Authors: Marronage .
Published: February 2020

The contribution is an intervention into the book Kolonierne i Vestindien [The Colonies in the West Indies] (1980) by Danish historian Ove Hornby. Pointing to the limitations and biases of Hornby's account of the St. Croix Fireburn labor revolt of 1878, the contribution is an implicit critique of the way archival sources have been put to use within the discipline of history writing in attempts to delegitimise anti-colonial resistance. It is with some ambivalence that we have chosen to also include an English translation of the Hornby text as well as our annotations, and thereby reproduce the very language we are critiquing. However, these translations have been important in order to ensure greater accessibility to a USVI readership.
Colonial media ecologies
Authors: Asp Frederiksen Lene
Published: February 2020

In this mixed-media essay I document a field trip to Ghana where I, so to say, travel in the footsteps of the Danish colonizers to the Gold Coast in a bid to dialogically challenge the genre of the monologizing colonial traveloguei. My methodological retracing of the slave route is inspired by Danish author Thorkild Hansen’s book trilogy Coast of Slaves, Ships of Slaves and Islands of Slaves from the 1960s in which he visits the former Danish West Indies and the Gold Coast (in the, at the time of his visit, still very young Ghanaian nation, which had gained its independence from Great Britain in 1957). Hansen was one of the first Danish authors to voice a strong critique of the Danish colonial past and of a neglectful historiography through his docu-fiction. I was curious to explore in a parallel movement to Hansen’s the landscape as prism and archive today. Hence, the ‘reenactment’ of the travelogue in this essay functions as an attempt to recast and refracture colonial  narratives of past and present. My own documentary audio recordings from the field trip are presented here along with methodological reflections on how to voice dialogical narratives about colonialism in new digital media.
Talent development environment in a professional football club in Norway
Authors: Flatgård Georg , Larsen Carsten Hvid , Sæther Stig Arve
Published: February 2020

The research on talent development is increasing, even though most of it has focused on the individual athlete. By using a holistic and ecological approach to talent development and especially the players’ environment, one could highlight how the environment facilitates player and team development. The purpose of this study was to analyse the recruit team of the professional football club Ranheim F.C. in Norway. Principal methods of data collection included interviews, participant observations of life in the environment, and analysis of documents. The environment was centred around the relationship between coaches and players, and although the supporting staff was relatively small, the inclusive and supportive approach from competent coaches was essential. The characteristics of the environment included that players were encouraged to take responsibility for their own development, exercise self-reflexiveness and the ability to handle the challenges that may arise in the life of young football players, and optimize the everyday lives of the players. Despite economic challenges within the club, the environment compensated with spirit, volunteerism, and hard work.
Elite athletes are higher on Grit than a comparison sample of non-athletes
Authors: From Line , Thomsen Dorthe Kirkegaard , Olesen Martin Hammershøj
Published: February 2020

This study examines whether grit and conscientiousness distinguish elite-sport performers from a comparison sample of non-athletes. Participants were 128 elite athletes and 1701 adults recruited through a human resource company. Both groups filled out short-form questionnaires measuring grit and conscientiousness. Consistent with expectations, there was a high positive correlation between grit and conscientiousness and the elite athletes reported higher grit than the non-athletes. Contrary to expectations, the non-athletes scored higher on conscientiousness compared to the elite athletes. The importance of grit for attaining elite status in sport is discussed.
Successful talent development environments in female Scandinavian Handball
Authors: Storm Louise Kamuk , Christensen Mette Krogh , Ronglan Lars Tore
Published: February 2020

Talent development is a sociocultural affair. The social learning perspective is rarely used for the study of talent development in sport, although it is broadly known in the domain of education. This article examines the way in which communities of practice are connected within two exceptional successful talent development environments, what characterises talents’ movements across communities of practice within the club, and what characterises the interactions between talents, senior players and coaches. Drawing on Wenger’s notion of communities of practice, constellations of interconnected practices and boundary encounters, it identifies how the two environments were characterised by (1) a well-functioning constellation of several CoPs, (2) opportunities for talents to participate and engage in various CoPs (3), individually adjusted feedback from coach to player combined with communication between the players with different positions in the CoPs and not only coach instructions, and (4) senior elite players’ engaging behaviours in regard to newcomers in the boundary encounters and thereby legitimate peripheral participation opportunities for talented players. (5) The coaches were the key to coordinate the interconnected practices and social interactions between the ‘youth CoP’ and ‘senior elite CoP’.

Artist-Writers: From Abstract-Expressionist Hostility to 1960s Canonicity
Authors: Carroll Leanne
Published: February 2020

Retraçant la réception des artistes-écrivains de la génération des expressionnistes abstraits et de celle de la génération minimaliste et les mettant en contraste, l’auteur évalue les conditions qui ont motivé un changement du statut des écrits d’artistes ; cette activité, qui avait d’abord été perçue comme une forme d’anomalie, allait en effet devenir une pratique tout à fait légitime et même instrumentale au succès de l’artiste. Alors que des artistes-écrivains tels Barnett Newman et Robert Motherwell avaient dû faire face à la méfiance et l’hostilité, Donald Judd a d’emblée été accepté comme un critique. Son essai « Specific Objects », même s’il s’en est défendu, a été lu comme un manifeste pertinent à son art ; il en fut de même de beaucoup d’autres minimalistes qui ont joint à leur pratique d’artistes une activité récurrente de critiques. Les raisons de ce changement sont multiples. Les artistes expressionnistes abstraits étaient reconnus pour avoir pratiqué une peinture instinctive, à laquelle s’opposait l’écriture, identifiée à un intellectualisme dont se méfiait la mentalité du temps. Mais si les valeurs idéologiques associées à la représentation de l’artiste en primitif convenaient à la société de l’après-guerre, les années 1960 allaient connaître une forme différente de cooptation liée en partie au succès des générations expressionnistes précédentes. Se dessine alors un nouveau modèle de l’artiste en professionnel, une figure hautement médiatisée, qui a appris à gérer sa carrière. Pendant que des développements dans la conception et dans la distribution de la presse artistique ouvrent des débouchés à la contribution écrite des artistes et qu’augmente l’intérêt de l’histoire de l’art pour la production contemporaine, le tournant linguistique qui marque la pensée critique du temps favorise un dialogue serré entre les arts visuels et l’écrit.
De l’invisibilité du capital : La Junte des Philippines de Goya (1815)
Authors: Occhietti Raphaelle
Published: February 2020

Despite its landmark status in Goya’s oeuvre, the painting The Assembly of the Royal Company of the Philippines (1815), more commonly known as The Junta of the Philippines, has attracted little scholarly attention. An austere and imposing painting, it is the depiction of a meeting of stockholders presided by a diminutive King Ferdinand VII in an interior setting that will be identified as a “finance room.” The canvas evinces a particular point of view on the relationships between the metropole and its faraway territorial possessions based on the absence of the colonies in the canvas. It will be argued that the pictorial setting of the finance room reasserts the virtual nature of the relationships between Madrid and its colonies. By comparing the Junta to contemporaneous British representations of spaces of finance, this study seeks to remove Goya’s work from the isolation in which previous accounts have largely kept it confined. This paper reveals the ways in which the mechanisms of late eighteenth and early nineteenth century finance capitalism were disclosed pictorially by one of the era’s most eminent artists.
Introduction au numéro thématique
Authors: Dejardin Marcus , Luc Sylvain , Thurik Roy
Published: February 2020

Dans ce bref article, nous motivons l’approfondissement de l’examen de la société entrepreneuriale en soulevant une série de questions assez générales, mais fondamentales pour qui souhaite la décrire et comprendre ses mécanismes. Avant d’examiner ces questions, nous fixons quelques balises sous forme de propositions. Nous en retenons deux à savoir, d’une part, l’unité d’observation et les niveaux auxquels se poseraient les enjeux fondamentaux de la société entrepreneuriale à savoir l’individu et l’interindividualité et, d’autre part, une proposition relative à la place du travail qui y occuperait une place centrale. Les questions soulevées esquissent un programme de recherche de grande ampleur.
L’institution imaginaire de la société entrepreneuriale : une enquête dans l’entrepreneuriat rap
Authors: Zidani Médine , Moriceau Jean-Luc
Published: February 2020

L’entrepreneuriat a toujours été associé à un imaginaire puissant. En prenant appui sur Castoriadis (1975), cette recherche explore certains enjeux de l’imaginaire dans le développement et la régulation de la société entrepreneuriale. Un récit autoethnographique complété par de l’observation participante montre que les pratiques et récits de l’entrepreneuriat rap peuvent être compris comme constitués à partir de l’imaginaire hip hop. Et que sous l’impulsion du développement des technologies numériques, l’imaginaire institué s’est en partie reformulé, toutefois à partir du même fond imaginaire instituant. L’imaginaire instituant est alors décrit comme un magma qui inspire et à partir duquel se créent les pratiques et institutions. Cette perspective invite à réfléchir à l’imaginaire instituant sur lequel s’érige la société entrepreneuriale dont Audrescht et Thurik prédisent l’avènement et aux imaginaires institués susceptibles de s’imposer.
Managing Universities for the Entrepreneurial Society: Entrepreneurial Loops and Innovative Teaching Initiatives
Authors: Ewango-Chatelet Aurelie
Published: February 2020

Drawing upon the entrepreneurial spirals concept, this article examines how managerial practices influence entrepreneurial intent in traditional academic activities. The international inquiry analyses innovative teaching into six business schools in France, Canada and Morocco. At the complex interplay between individual goals and organizational objectives, three entrepreneurial loops are identified: converging, diverging and absence of loop. Findings suggest that university management remains a challenge as an appropriate balanced management is required for the changing university’s mission towards social and economic well-being. The conditions of successful academic entrepreneurial activities are outlined across three propositions.
Le travail indépendant contemporain : regards croisés à partir des mutations du salariat et de l’indépendance
Authors: D’Amours Martine
Published: February 2020

Depuis le milieu des années 1970, le travail indépendant a connu au Canada et au Québec une croissance marquée, en grande partie attribuable aux indépendants qui exercent seuls, sans l’aide d’employés. Si ces derniers possèdent de manière disproportionnée les attributs de la précarité, une réalité qu’ils déplorent, ils témoignent d’une quête de flexibilité et de liberté, aspects appréciés quoique inégalement concrétisés. L’article se propose de jeter un éclairage sur cet apparent paradoxe, grâce à une analyse croisée des mutations qui ont affecté, d’une part le salariat et, d’autre part, le travail indépendant.
L’idée en peinture au XVIIe siècle
Authors: Dauvois Daniel
Published: February 2020

In a letter to Chantelou dated 22 December 1647, Poussin writes of a painting to be executed that he has found its thought, “I mean the conception of the idea, and the work of the mind was complete.” It follows that Poussin’s idea belongs to the theoretical component of painting, namely the composition, and the idea constitutes the represented object aimed at by invention, which converts a historia into a picture and whose procurement provides sufficient satisfaction to an erudite painter like Poussin. Idea is the end or aim of pictorial thought and the regulative means for producing the visible work. Beyond a then perceptible tension between an ideal, indeed a divine Idea, to which Félibien’s idea of the painter comes close in his first Entretien, and an agent or force of conversion of the discursive into the figural, idea belongs henceforth also to the theory of the art of painting, as is witnessed by the titles of works by Fréart or Roger de Piles (Idée de la perfection de la peinture, Idée du peintre parfait): such an idea is thus a regulated presentation of what the painter must do if he wishes to excel. It is no longer conceived or made visible by the painter, but by a kind of enlightened connoisseur, not yet called a critic, but who distances himself sufficiently from the art of painting to teach and to adjudicate good taste. Not only does idea then aid, not in the fabrication of good paintings, but rather in the evaluation of painting, as Roger de Piles underlines at the end of his opuscule introducing the Abrégé de la vie des peintres, but it could well be formative or constitutive of taste itself—a shift by which Idea comes, by the century’s end, to regulate not the production of works, but the judgments passed on them.
On rit au NarKomPros : Anatoli Lounatcharski et la théorie du rire soviétique
Authors: Gérin Annie
Published: February 2020

In 1930 Anatoly Lunacharsky, Soviet Commissar of Enlightenment from 1917 to 1929, set up a government commission to study satirical genres in the visual arts, literature, music, theatre, and film. At the same time, he was working on the manuscript for a book entitled The Social Role of Laughter, which he never completed. Throughout his career as Commissar, Lunacharsky was instrumental in producing much satirical work through government contracts and commissions allocated to artists. During those years he also wrote art criticism and theoretical texts that encouraged Soviet artists to use humour and satire as a tool for social criticism and change in the context of the emerging Soviet Union. These writings were inspired by the prevalent theories of laughter (mainly those of Freud, Bergson, Spencer, Sully, and Lipps), revisiting them through the lens of Marxism, and translating them into a very specific Soviet language and worldview. Although they were published in Soviet journals, they remain virtually unknown. This essay examines Lunacharsky’s theoretical contribution to the study of laughter and its influence on the production of visual satire in the first decades of the Soviet Union.
The Gravity of Levity: Humour as Conceptual Critique
Authors: Diack Heather
Published: February 2020

Parmi les nombreuses antinomies qui traversent les écrits issus de l’art conceptuel et les textes analytiques qui en traitent, l’une des plus importantes, et pourtant des moins explorées, est celle qui oppose les différentes conceptions de l’humour. Ces conceptions proviennent d’approches de l’humour que l’on pourrait qualifier soit de subversive et déstabilisante, soit d’analytique et contraignante. Bien que ces catégories ne s’excluent pas esthétiquement et philosophiquement l’une l’autre, elles ont pourtant été mises en opposition de façon systématique. Cet article examine l’histoire de cette tension afin de souligner son importance pour la compréhension de ce qu’a été l’art conceptuel. Il accorde, entre autres, une large place au débat entre l’interprétation doctrinaire de Joseph Kosuth et l’interprétation subversive de John Baldessari de l’humour duchampien. L’humour devient dès lors un catalyseur privilégié permettant d’interroger les finalités esthétiques et philosophiques de l’art conceptuel. Finalement, ce texte, à l’aide des concepts de légèreté (levity) et de pesanteur (gravity), fait la cartographie de la brèche qui passe entre un humour débridé et un humour hermétique.
Embodying the Nation: Art, Fashion, and Allegorical Women at the 1900 Exposition Universelle
Authors: Dymond Anne
Published: February 2020

Notre article s’intéresse à la façon dont l’Exposition Universelle de 1900 s’est servi du corps féminin pour dessiner la relation entre la France, Paris et les provinces. Le contraste marqué entre les représentations de La Parisienne et celles de ses soeurs de province laisse apparaître une série d’enjeux conflictuels liés à la consommation et la production, la modernité et la tradition, l’évolution et l’immobilisme. Nous nous intéressons en particulier ici à l’entrée principale construite pour l’exposition, la Porte Monumentale, afin d’explorer la manière dont l’exposition a construit la nation dans un rapport discursif de centre à périphérie. En dépit d’une rhétorique situant l’exposition dans une perspective de décentralisation, l’exposition de 1900 s’est effectivement servie d’allégories géographiques sexuées pour donner aux relations entre la nation, sa capitale et ses régions une apparence harmonieuse, alors que celles-ci se trouvaient dans un rapport fortement hiérarchisé et politisé. Prenant pour exemple le cas de la Provence, je conclus en examinant comment les groupes régionaux ont tiré profit de leurs moyens limités pour s’insérer dans le récit national.
