Criminological analysis of bullying, its types, signs and methods of prevention
Authors: Krusir Nataliia
Published: July 2021

The article is devoted to the study of the criminological side of such a phenomenon as bullying, its concepts, signs and types. The historical development of the study of the concept of «bullying» is traced. The research of various scientists in the field of studying such a phenomenon as bullying is analyzed. The relationship between bullying and other forms of violent behavior is investigated. The main determinants that contribute to such actions are analyzed. One of the types of bullying is considered - cyberbullying, which is a form of aggressive, conflict behavior of a systematic nature, carried out using modern information and telecommunications. Lists the types of cyberbullying that occur in cyberspace, as well as the types of behavior that are characteristic of this phenomenon. The consequences of bullying are described and actions in bullying are compared with actions that qualify under Article 120 «Inducing to suicide» of the Criminal Code of Ukraine and Article 128 «Torture» of the Criminal Code of Ukraine. Discloses a concept such as «Bulicide». Emphasis is placed on the problem of preventing and combating bullying in Ukraine. The Laws of Ukraine “On Amendments to Certain Legislative Acts of Ukraine on Countering Bullying (Harassment)” and “On Education” are analyzed to identify actions that qualify as bullying. The administrative responsibility provided for commission of these actions is specified. To counteract and prevent such a negative phenomenon in Ukraine as bullying, it is proposed to improve the legislation that would clearly regulate this issue and strengthen the responsibility for bullying, as well as take measures to prevent this phenomenon at the national, special criminological and individual levels. In addition, given the threat to human life and health, as well as the age of adolescents, who have recently become bullying, the common signs of bullying and torture, it is proposed to equate certain types of bullying to torture, and proposed consideration of criminal -legal liability for bullying, children who have reached 14 years. The best ways to solve the problem of bullying are proposed, considering foreign experience. Keywords: bullying, violence, cyberbullying, criminal liability, counteracting bullying, measures to prevent bullying.

Authors: Gio Phan Dinh , Chi Huynh Thi , Tu Le Tran Uyen , Tho Nguyen Truong
Published: July 2021

Samples of 0.96(K0.48Na0.48Li0.04)(Nb0.95Sb0.05)O3-0.04Bi0.5(Na0.82K0.18)0.5ZrO3 piezoelectric ceramic were fabricated with conventional ceramic techniques and sintered at different temperatures. The effect of sintering temperature (TS) on the structure, microstructure, and piezoelectric properties of the ceramics was studied in detail. The experimental results showed that with an increase of the TS temperature, the structure of the ceramics transformed from an orthorhombic-tetragonal mixed phase (O-T) at TS £ 1100 °C into a rhombohedral-tetragonal (R-T) mixed phase with a dense microstructure of uniform grain size at TS = 1110 °C. When TS was further increased (TS ³ 1120 °C), the ceramics showed only a rhombohedral phase (R). The ceramics showed the best electrical properties for TS = 1110 °C at which the rhombohedral and tetragonal (R-T) phases coexist. Specifically, the ceramic density reached its highest value (4.22 g/cm3), the electromechanical coupling coefficients kp and kt were 0.46 and 0.50, respectively, and the piezoelectric coefficient d33 was 245 pC/N.

Influence of Composition of Power Plant Fleets and Ownership of Transmission and Distribution Networks to Incumbent Company’s Business Success in Some Former Socialist EU Countries
Authors: Komljenovic Krešimir
Published: July 2021

By joining the EU, companies from eastern countries, which until then had largely operated in regulated circumstances, had to adapt to the open market. Liberalization and deregulation were imposed on them as new mantras, in contrast to ensuring the supply at all costs and addressing social issues. How these companies flourished in new circumstances is a legitimate topic for managerial research. This article researches the impact of the "hard assets" composition, that those companies operated, on their expected business success after a multi-year adjustment period. Positivistic research philosophy, "case study", and the deduction approach are used. The data were collected mainly from secondary sources. 3 research goals were selected with 3 relevant research questions. An attempt was made to respond to them on the example of 7 Central European countries and 11 companies, direct successors of original incumbents. The property is grouped into 3 groups: classical power plants (nuclear, hydro, coal), renewable power plants (wind, solar, bio mass) and lines (transmission and distribution). Criteria for success are selected according to usual praxis, but also adjusted to accessible data, predominantly from the company's annual financial statements. Contrary to the developed intuition, and based on cases of companies analyzed, there was no significant correlation between the selected criteria of success and the observed asset classes, serving as independent variables. The biggest problem in the research was access to data. This paper is an extraction from an MBA dissertation.

Kebiasaan Buang Air Besar Sembarangan adalah praktik membuang tinja disembarang tempat terbuka yang mengakibatkan pencemaran lingkungan. Berdasarkan data dari Puskesmas Dumai Kota, salah satunya yaitu di Kelurahan Laksamana. Dari jumlah 811 jiwa yang memiliki sanitasi belum layak masyarakat masih melakukan BABS. Hal ini di sebabkan karena masih memiliki pengetahuan yang rendah dan kurangnya informasi tentang dampak dari BABS. dan Ekonomi masyarakat terutamanya menjadi salah satu penyebab, dikarenakan pekerjaan masyarakat tersebut belum mendapatkan hasil yang cukup sehingga memungkinkan masyarakat sulit untuk membuat jamban yang layak. Penelitian ini bertujuan untuk mengetahui faktor yang berhubungan sanitasi dasar, pengetahuan, sikap dan pendapatan terhadap kebiasaan BABS di Kelurahan Laksamana wilayah kerja Puskesmas Dumai Kota. Penelitian ini menggunakan desai Cross Sectional dan menggunakan teknik sampel Stratified Random Sampling. Sampel sebanyak 91 responden. Variabel Independen pada penelitian ini adalah kondisi jamban, sumber air bersih, pengetahuan, sikap dan pendapatan. Variabel dependen adalah kebiasaan buang air besar sembarangan.

Introducere. Tratamentul minim-invaziv al hidronefrozei congenitale la copil rămâne un subiect controversat, atât prin prisma momentului şi criteriilor operatorii, cât şi prin adresarea tehnicilor laparoscopice la sugar şi copilul mic. Material şi metodă. Studiul îşi propune analiza criteriilor operatorii ale unui lot de pacienţi operaţi laparoscopic pentru hidronefroză congenitală în perioada 2007-2015, în cadrul Clinicii de Chirurgie Pediatrică a Spitalului Clinic de Urgenţă pentru Copii „M.S. Curie“, Bucureşti. Rezultate. În lotul studiat, cel mai frecvent criteriu utilizat pentru indicaţia chirurgicală este dilataţia bazinetului peste 3 cm, urmat de alterarea (sub 50%) a grosimii parenchimului, alterarea funcţionalităţii renale sub 40% şi în final criteriile simptomatice – infecţiile urinare şi durerile colicative lombare. Atât dilataţia bazinetului cât şi grosimea parenchimului renal se corelează cu funcţia renală, corelaţia fiind mai puternică pentru grosimea parenchimului renal. Sugarii sub 1 an şi sub 10 kg au fost reprezentaţi în proporţie semnificativă (17,5% şi respectiv 22,5%). Concluzii. Vârsta mică (sub 1 an) şi greutatea redusă (sub 10 kg) a pacientului nu constituie un motiv de temporizare a tratamentului chirurgical. Pielectazia nu este specifică sindromului de joncţiune pielo-ureterală, poate apărea în absenţa unei obstrucţii şi nu prezintă întotdeauna o corelaţie puternică cu alterarea funcţiei renale. Elementele de bază în stabilirea conduitei terapeutice sunt: amploarea restructurărilor parenchimatoase renale, gradul afectării funcţiei renale şi simptomatologia clinică. Tratamentul laparoscopic este o soluţie chirurgicală care întruneşte toate avantajele minim-invazivităţii, aplicabilă copiilor şi sugarilor, indiferent de vârstă şi greutate.

Hemihypertrophy or hemihyperplasia is a rare congenital condition, whose incidence is difficult to estimate, due to the fact that asymmetry is very mild, therefore remaining undiagnosed. Hemihyperplasia can be isolated or associated to certain genetic syndromes. We present the case of a 6-months-old female infant, in whom, during the neonatal period, was raised the suspicion of a congenital hemihypertrophy. She was admitted in our clinic due to the presence of a facial asymmetry. The clinical exam revealed also, besides the hemihyperplasia of the right hemiface more obvious at the level of the forehead, a hypertrophy of the right superior and inferior limbs. The laboratory tests identified a mild anemia, increased levels of transaminases and alfa-fetoprotein. The abdominal ultrasound revealed a mild hepatomegaly and the transfontanellar one discrete ventriculomegaly and frontal atrophy. The genetic test was negative, therefore the final diagnosis was of isolated hemihypertrophy. The further re-evaluations showed a decreasing level of alfa-fetoprotein, without other additional pathological elements. The particularity of the case consists in diagnosing an isolated hemohypertrophy in a 6-month-old female infant, with negative genetic test, in whom it was observed at the moment of birth a mild facial asymmetry, with afterwards favorable evolution, with progressive decrease of the alfa-fetoprotein level and normal abdominal ultrasound.

Rinosinuzita cronică (RSC), este o patologie rară în pediatrie comparativ cu adultul. Manifestările clinice sunt în relaţie, pe de o parte, cu particularităţile anatomice, iar pe de altă parte, cu cele de răspuns imun corelate cu vârsta copilului. Alergia constituie cauza principală în 50% dintre rinitele copilului, 40% dintre acestea debutând precoce până la vârsta de 6 ani. Expresia clinică a rinosinuzitei alergice la copil poate fi uneori însoţită de manifestări ale comorbidităţilor alergice asociate sau de complicaţii de vecinătate. Alterarea clearance-ului mucociliar poate fi însă indus şi de alte situaţii patologice mai rare care produc modificarea proprietăţilor reologice ale mucusului, ca în mucoviscidoză (FC). Prin heterogenitatea de expresie clinică în relaţie pe de o parte cu particularităţile de răspuns imunogenetic şi anatomice raportate la vârsta copilului şi pe de altă parte cu diversitatea factorilor etiologici inductori (de la foarte frecvenţi, precum alergia, la foarte puţin frecvenţi, FC), RSC impune un diagnostic corect, precoce şi un tratament adecvat prin colaborarea în echipă multidisciplinară.

În întreaga lume, naştereа prematură este principala cauză a mortalităţii infantile şi o cauză semnificativă a pierderii potenţialului uman de prematuri supravieţuitori pentru următoarele etape de viaţă. Obiectiv. Determinarea ratei de supravieţuire a nou-născuţilor prematuri în funcţie de nivelul de acordare a asistenţei medicale şi factorii de risc principali implicaţi în decesul nou-născuţilor prematuri cu termenul de gestaţie mai mic de 34 de săptămâni. Material şi metodă. Au fost luaţi în studiu 750 de nou-născuţi prematuri repartizaţi în trei loturi astfel: lotul I – 476 de nou-născuţi prematuri din IMSP IMşiC Chişinău (maternitate de nivel III); lotul II – 240 de nou-născuţi prematuri transferaţi din maternităţi de nivel I şi II prin linia AVIASAN şi lotul III – 34 de nou-născuţi prematuri din IMSP IMşiC Chişinău cărora li s-a administrat surfactant prin metoda LISA (Less Invasive Surfactant Administration). S-a efectuat o analiză complexă privind factorii de risc pentru mortalitate şi impactul pozitiv al condiţiilor de îngrijire. Datele au fost analizate folosind soft-ul SPSS V.21. (IBM Statistical Package for the Social Sciences, Chicago, Illinois). Rezultate. Rata de supravieţuire la 78 de zile de viaţă fost semnificativ mai mare în cazul nou-născuţilor proveniţi din maternităţi de nivel III, care au urmat terapie LISA (93,3%), comparativ cu nou-născuţii din loturile I (78,2%) şi II (78,9%). Concluzii. Supravieţuirea nou-născuţilor prematuri este o problemă multifactorială. Factorul principal ce determină rata de deces a acestor nou-născuţi îl reprezintă sindromul de detresă respiratorie (SDR), fiind urmat de greutatea la naştere (GN), vârsta de gestaţie (VG), metoda de resuscitare, displazia bronhopulmonară (DBP) şi, nu în ultimul rând, nivelul maternităţii de provenienţă. Posibilităţile moderne de reanimare a prematurilor, din maternităţi de gradul III, cresc semnificativ speranţa de viaţă a prematurilor cu vârsta gestaţională mai mică de 34 de săptămâni.

NT - 49 - Diest - Perfil racial do serviço civil ativo do Executivo Federal (1999-2020)
Authors: Dias Tatiana Silva , Lopez Felix
Published: July 2021

A questão racial desempenha um papel estruturante e central no conjunto das desigualdades da sociedade brasileira, como tem sido fartamente documentado (Ipea, s.d.; Ipea e FBSP, 2018; Ipea e Seppir, 2014; Marcondes et al., 2013; Paixão et al., 2010; Silva, 2012). Apesar de o ingresso no setor público exigir, em sua maioria, concurso público – o que poderia levar a pensar que este setor estaria mais protegido dessas desigualdades que estruturam a sociedade e o mercado de trabalho –, elas também se manifestam neste espaço. O acesso, progressão e promoção nas carreiras e cargos, especialmente nos postos de maior prestígio e comando, frequentemente são desfavoráveis à população negra, constituída por pretos e pardos (Silva e Silva, 2014).
No início dos anos 2000, implementaram-se as primeiras políticas de ação afirmativa no país. Embora o foco dessas políticas – e do debate público – tenha se voltado para as instituições públicas de ensino superior, nesse período também se difundiram programas de reserva de vagas para negros em concursos públicos. Em 2012, já havia mais de quarenta iniciativas no país, entre estados e municípios (Volpe e Silva, 2016).
Cerca de uma década após as primeiras iniciativas, o governo federal implementou iniciativa similar, destinando 20% das vagas em concursos públicos para a população negra, por meio da Lei n° 12.990/2014. Atualmente, medidas equivalentes são adotadas em todos os Poderes e níveis federativos. Após anos de implementação, a exemplo
da lei federal citada, há poucas avaliações sobre os resultados alcançados. Com vistas a contribuir para reflexões sobre a implementação do sistema de reserva de vagas para negros no governo federal e, especialmente, sobre a representação da população negra no funcionalismo, esta Nota Técnica apresenta a trajetória e os aspectos da distribuição racial dos postos de trabalho, principalmente no quadro dos servidores civis ativos do Poder Executivo federal (civil). Para tanto, explora dados do Sistema Integrado de Administração de Recursos Humanos (Siape), responsável pela gestão de informações de pessoal no Executivo federal. Apenas recentemente, foram disponibilizadas algumas consultas públicas, ainda limitadas, sobre a cor e raça dos servidores federais. Desse modo, o texto também visa, ao descrever os dados, ampliar o conhecimento público e estimular maior incorporação do tema racial na análise da composição do funcionalismo brasileiro. Por essa razão, a nota tem cunho exploratório e descritivo, com o intento de apresentar um panorama inicial e indicativos para análises futuras. Além desta introdução, o texto conta com uma seção com informações gerais sobre o funcionalismo público, seguida de detalhamentos de alguns dos dados disponíveis no Siape com desagregação por cor ou raça. Por fim, são apresentadas considerações finais e sugestões para novos estudos.

The Akan Traditional Leadership Formation: Some Lessons for Christian Leadership Formation
Authors: Opuni-Frimpong Kwabena
Published: July 2021

Traditional and Christian leaders in Akan communities in Ghana provide leadership services for the same Akan people. For proper internal harmony and identity devoid of identity crises, the two leadership systems should not only understand each other but must be willing to learn relevant values and lessons from each other. The integration which has already taken place among Akan traditional leaders as they have over the years learnt Christian leadership values and lessons from churches and mission schools is yet to take place properly in Christian leadership formation. This article seeks to analyse the values and lessons in Akan traditional leadership formation and its significance for Christian leadership formation. Observation and interviews of the Akan traditional leadership institution at Akuapim, Akyem and Asante and examination of secondary materials on early interpreters of the interaction between the Akan traditional leadership institution with the Christian faith are used to gather qualitative data. Akan traditional leadership formation pays much attention to matters of royal consciousness, leadership as service, mentoring, the celebration of the Adae festival and oath swearing. Christian leadership formation that seeks to avoid the church being alien on Akan cultural soil will need to pay attention to the indigenous leadership formation when addressing issues on institutional memory, stewardship, women in leadership, leadership as service and accountability in Christian leadership.

Keywords: Akan, Christian, Traditional Leadership, Leadership Formation.
Extreme-ultraviolet Late Phase in Homologous Solar Flares from a Complex Active Region
Authors: Zhong Y. , Dai Y. , Ding M. D.
Published: July 2021

Recent observations in extreme-ultraviolet (EUV) wavelengths reveal a new late phase in some solar flares, which is seen as a second peak in warm coronal emissions (∼3 MK) several tens of minutes to a few hours after the soft X-ray peak. The origin of the EUV late phase (ELP) is explained by either a long-lasting cooling process in the long ELP loops or a delayed energy ejection into the ELP loops well after the main flare heating. Using the observations with the Solar Dynamics Observatory, we investigate the production of the ELP in six homologous flares (F1–F6) originating from a complex active region (AR), NOAA Active Region 11283, with an emphasis on the emission characteristics of the flares. It is found that the main production mechanism of the ELP changes from additional heating in flare F1 to long-lasting cooling in flares F3–F6, with both mechanisms playing a role in flare F2. The transition is evidenced by an abrupt decrease of the time lag of the ELP peak, and the long-lasting cooling process in the majority of the flares is validated by a positive correlation between the flare ribbon fluence and the ELP peak intensity. We attribute the change in ELP production mechanism to an enhancement of the envelope magnetic field above the AR, which facilitates a more prompt and energetic heating of the ELP loops. In addition, the last and the only confined flare F6 exhibits an extremely large ELP. The different emission pattern revealed in this flare may reflect a different energy partitioning inside the ELP loops, which is due to a different magnetic reconnection process.
The Black Hole Mass of NGC 4151 from Stellar Dynamical Modeling
Authors: Roberts Caroline A. , Bentz Misty C. , Vasiliev Eugene , Valluri Monica , Onken Christopher A.
Published: July 2021

The mass of a supermassive black hole (M
BH) is a fundamental property that can be obtained through observational methods. Constraining M
BH through multiple methods for an individual galaxy is important for verifying the accuracy of different techniques and for investigating the assumptions inherent in each method. However, there exist only a few galaxies where multiple M
BH measurement techniques can be applied. NGC 4151 is one of these rare galaxies for which multiple methods can be used: stellar and gas dynamical modeling because of its proximity (D = 15.8 ± 0.4 Mpc from Cepheids), and reverberation mapping because of its active accretion. In this work, we reanalyzed H-band integral field spectroscopy of the nucleus of NGC 4151 from Gemini NIFS, improving the analysis at several key steps. We then constructed a wide range of axisymmetric dynamical models with the new orbit-superposition code Forstand. One of our primary goals is to quantify the systematic uncertainties in M
BH arising from different combinations of the deprojected density profile, inclination, intrinsic flattening, and mass-to-light ratio. As a consequence of uncertainties on the stellar luminosity profile arising from the presence of the active galactic nucleus, our constraints on M
BH are rather weak. Models with a steep central cusp are consistent with no black hole; however, in models with more moderate cusps, the black hole mass lies within the range of 0.25 × 107
M
⊙ ≲ M
BH ≲ 3 × 107
M
⊙. This measurement is somewhat smaller than the earlier analysis presented by Onken et al. but agrees with previous M

Time series of spectroscopic, speckle-interferometric, and optical long-baseline-interferometric observations confirm that ν Gem is a hierarchical triple system. It consists of an inner binary composed of two B-type stars and an outer classical Be star. Several photospheric spectral lines of the inner components were disentangled, revealing two stars with very different rotational broadening (∼260 and ∼140 km s−1, respectively), while the photospheric lines of the Be star remain undetected. From the combined spectroscopic and astrometric orbital solution it is not possible to unambiguously cross identify the inner astrometric components with the spectroscopic components. In the preferred solution based on modeling of the disentangled line profiles, the inner binary is composed of two stars with nearly identical masses of 3.3 M
⊙ and the more rapidly rotating star is the fainter one. These two stars are in a marginally elliptical orbit (e = 0.06) about each other with a period of 53.8 days. The third star also has a mass of 3.3 M
⊙ and follows a more eccentric (e = 0.24) orbit with a period of 19.1 yr. The two orbits are codirectional, and at inclinations of 79° and 76° of the inner and the outer orbit, respectively, about coplanar. No astrometric or spectroscopic evidence could be found that the Be star itself is double. The system appears dynamically stable and not subject to eccentric Lidov–Kozai oscillations. After disentangling, the spectra of the components of the inner binary do not exhibit peculiarities that would be indicative of past interactions. Motivations for a wide range of follow-up studies are suggested.

I present WISEA J052305.94–015356.1 as a new candidate extremely metal-poor T subdwarf (esdT), based on its distinctive infrared colors and high proper motion (∼500 mas yr−1). Spectroscopic follow-up is now needed to confirm it is a member of this newly discovered class of substellar objects.
Energetic underpinnings of yellow dung fly mating success in the field
Authors: Blanckenhorn Wolf U.
Published: July 2021

Foraging provides the basis for animal reproduction, but requires energy and time to be sustained, entailing a trade-off. Whereas females should maximize their time foraging for resources, males should minimize their foraging time by optimizing time budgets to maximize their access to mating partners.

Mark-resight field studies are difficult and hence uncommon for small insects. Yellow dung flies (Scathophaga stercoraria L.) abound on pastures in cold-temperate regions across the northern hemisphere. Adult flies lick nectar from flowers for energy, but require small insect prey to produce eggs and sperm. Males wait for females around fresh cow dung, but at one point also need to replenish their energy and/or sperm reserves in the surrounding vegetation. Their foraging time budgets should depend on their body size, nutritional energy reserves, availability of sperm, competitor and female density.

Marked male dung flies whose nutritional status was experimentally manipulated – water only (null control); water + sugar (energy replenishment); or water, sugar + Drosophila prey (energy and sperm replenishment) – were repeatedly observed on an experimental pasture for an entire day. Both nutrient types were expected to increase the mating success of especially large males.

The total number of resighted males seen copulating was lowest for water-treated flies. Mating success was positively related to body size. The distance travelled between dung pats was greater for males fed sugar or prey and also increased with body size, while pat residence times decreased with size. No differences were found between the sugar- and prey-fed groups. Crucially however, there was no evidence in the field for a time budget or mating advantage of small males when nutrients were limited.
Database “Childfree (antinatalist) communities in the social network VKontakte”
Authors: Kalabikhina Irina E. , Banin Evgeny P.
Published: July 2021

The database contains an upload of text comments in Russian from the social network VKontakte in .csv format (UTF-8 encoding). The comments are collected from communities, which discuss pregnancy, childhood, motherhood, paternity, etc. The upload contains comments under the posts with which the interaction took place. The absolute amount of likes is used as a criterion (comments are collected where the number of likes is greater than or equal to 5). The text data is processed (stemmization and lemmatization).

The data are suitable for thematic analysis (e.g. LDA — Latent Dirichlet Allocation), sentiment analysis of statements, modelling the graph structure of communities (the link_comment variable contains a unique identifier of the post, link_author contains a unique user identifier), and forming a dictionary of demographic connotation in Russian. Sentiment analysis of statements enables measuring the dynamics of «demographic temperature» in antinatalist communities.

The database is a supplement to the publication Kalabikhina IE, Banin EP (2020) Database «Pro-family (pronatalist) communities in the social network VKontakte». Population and Economics 4(3): 98–130. https://doi.org/10.3897/popecon.4.e60915.
Variability in macrozoobenthic assemblages along a gradient of environmental conditions in the stream water of karst caves (Lower Shakuranskaya Cave, western Caucasus)
Authors: Borisov Rostislav R. , Chertoprud Elena S. , Palatov Dmitry M , Novichkova Anna A.
Published: July 2021

The fauna of the stream water in the Lower Shakuranskaya Cave in central Abkhazia, western Caucasus, was studied. This cave has a large inlet and an extended entrance ecotone area of approximately 60 m, which makes it a convenient area for studying macrozoobenthic assemblages across a gradient of environmental factors. The cave has 13 species of stygobionts, 10 species of stygophiles and 18 species of stygoxenes. The number of species and the abundance and biomass of stygobionts per station were the highest near the boundary of the photic zone, at a distance of 50–60 m from the entrance to the cave, and gradually decreased toward both the remote parts of the cavity and the cave exit. The most abundant stygobionts were gastropod mollusks of the Hydrobiidae family, and Xiphocaridinella shrimp comprised the main part of the biomass. It has been shown that the main environmental factors determining the distribution of macrozoobenthos are luminosity and distance from the entrance to a cave. According to the differences in their reactions to these environmental factors, several groups of species were identified. In addition, three main assemblages of macrozoobenthic species were described: (1) an assemblage of epigean species near the cave entrance area; (2) stygobionts in remote parts of the cave outside the photic zone; and (3) a mixed assemblage in the cave ecotone, where a faint light penetrates. The specific details related to the faunal structure in the ecotone of the cave are discussed, as well as active and passive methods by which stygoxenes invade underground cavities.
Lutter contre la maltraitance entre résidents dans les établissements locatifs réservés aux aînés autonomes et semi-autonomes au Québec
Authors: Leboeuf Roxane , Beaulieu Marie , Tschopp Françoise
Published: July 2021

Notre recherche-action est issue de l’initiative de trois établissements locatifs à but lucratif accueillant des aînés autonomes et semi-autonomes au Québec préoccupés par des situations de maltraitance entre leurs résidents. Au moyen d’entrevues de groupes avec des résidents, des employés et des gestionnaires, elle visait à documenter ce problème en conjugaison avec la bientraitance entre les résidents. Notre article discute plus spécifiquement des actions posées afin de lutter contre la maltraitance et de promouvoir la bientraitance entre les résidents. Les enjeux soulevés et les pistes d’actions proposées invitent à questionner les limites des compétences attendues chez les employés ainsi que l’offre de services de ces établissements, puis à réfléchir le travail de concertation avec les organisations dans la communauté.
Aux sources du test de Rorschach : introduction historique aux psychoscopes
Authors: Evrard Renaud , Frigaux Antoine
Published: July 2021

Le « test d’interprétation libre de formes fortuites » conçu par Hermann Rorschach est la forme la plus célèbre de l’utilisation des taches d’encre dans l’investigation psychologique. Les sources d’inspiration de ce test sont multiples. Les plus évidentes sont l’influence de ses collègues psychiatres Carl Gustav Jung (test d’association de mots), Herbert Silberer (lécanomancie) et Szymon Hens (taches d’encre et fonction imaginative). Néanmoins, d’autres sources sont identifiables dans les pratiques mantiques qui, depuis l’Antiquité, stimulent les automatismes sensoriels et moteurs. Ces pratiques ont fait l’objet de réappropriations au cours du xix e  siècle, dans le cadre de la première psychiatrie dynamique, jusqu’à ce que, dans la voie établie par l’Anglais Frederic Myers et ses études de l’écriture automatique et de la vision dans le cristal, le « psychoscope » (terme désignant tout dispositif qui permet l’émergence des automatismes moteurs ou sensoriels) soit proposé comme instrument essentiel de la psychologie expérimentale. Nous proposons une histoire à rebours identifiant ces possibles influences pour Rorschach lors de l’élaboration de son matériel et du système d’interprétation de son test. L’opposition épistémologique entre adeptes du « psychoscope » et du « chrono-scope » semblent se rejouer dans les controverses contemporaines sur l’évaluation des propriétés psychométriques des tests projectifs.
L’enquête comme vecteur d’affordance et le terrain comme écosystème
Authors: Albero Brigitte , Simonian Stéphane
Published: July 2021

La relation entre chercheur et informateur implique de questionner, mais aussi de situer les fondements et déroulements de l’enquête scientifique car s’ils ont des incidences sur les résultats, ils en ont aussi sur les conséquences de ces résultats. Pour dépasser nombre de disjonctions contre-productives, l’analyse proposée dans cet article situe l’enquête scientifique dans une approche écologique où les constituants de l’enquête (concepts, acteurs, instruments) et la nature de leurs interrelations permettent de rendre compte des conceptions sous-jacentes mais aussi du type de résultats produits. Les conditions de réalisation d’une enquête scientifique en Sciences de l’Education et de la Formation deviennent ainsi objet d’étude par l’analyse des affordances qu’elles produisent dans l’environnement où sont mises en œuvre. Il est ainsi montré qu’en matière d’enquête à propos de l’activité humaine, la démarche d’enquête peut avoir autant d’importance que les résultats obtenus, sinon plus…
Mettre au jour une dimension peu renseignée du travail des psychomotriciens : un enjeu pour la recherche et une occasion de développement professionnel
Authors: Paggetti Marion
Published: July 2021

Cette contribution renseigne les effets d’une démarche d’analyse du travail auprès de professionnels du soin grâce aux matériaux d’une recherche doctorale se donnant pour objet l’intelligibilité d’une forme d’activité peu renseignée et qui « résiste » à la mise en mots : les interactions corporelles de soin entre psychomotriciens et patients-enfants. En appui sur le cadre conceptuel de J. Dewey, la contribution montre comment l’explicitation d’une dimension peu formalisée de leur travail est l’occasion pour les professionnelles participant à la recherche de mener une enquête sur l’enquête et apprendre de leur propre activité d’ajustement corporel.
Pluralisme des savoirs et reconfigurations de l’agir au travail
Authors: Schwartz Yves , Duc Marcelle
Published: July 2021

A la question qu’est-ce que l’analyse du travail fait au travail, ce texte s’attache dans une première partie à définir ce que l’on entend par travail en développant un point de vue ergologique. Premièrement, le travail renvoie à une tentative permanente de négociation avec les normes. Deuxièmement, toute forme d’intervention sur le travail caractérise deux formes de savoirs (conceptuels et de la renormativité) auxquels se confrontent à la fois enquêteurs et sujets enquêtés. Troisièmement, les transformations dans la façon de faire son travail, provoquées par l’intervention, sont liées à la posture de « Dispositif dynamique à trois pôles ». La seconde partie vise alors à se demander en quoi cette posture transforme le faire éducatif scolaire et notamment le métier de formateur-enseignant-chercheur.
Global stability of traveling wave fronts in a two-dimensional lattice dynamical system with global interaction
Authors: Cheng Cui-Ping , An Ruo-Fan
Published: July 2021

This paper is concerned with the traveling wave fronts for a lattice dynamical system with global interaction, which arises in a single species in a 2D patchy environment with infinite number of patches connected locally by diffusion and global interaction by delay. We prove that all non-critical traveling wave fronts are globally exponentially stable in time, and the critical traveling wave fronts are globally algebraically stable by the weighted energy method combined with the comparison principle and the discrete Fourier transform.
A stabilizer free WG method for the Stokes equations with order two superconvergence on polytopal mesh
Authors: Ye Xiu , Zhang Shangyou
Published: July 2021

A stabilizer free WG method is introduced for the Stokes equations with superconvergence on polytopal mesh in primary velocity-pressure formulation. Convergence rates two order higher than the optimal-order for velocity of the WG approximation is proved in both an energy norm and the $ L^2 $ norm. Optimal order error estimate for pressure in the $ L^2 $ norm is also established. The numerical examples cover low and high order approximations, and 2D and 3D cases.
A simple virtual element-based flux recovery on quadtree
Authors: Cao Shuhao
Published: July 2021

In this paper, we introduce a simple local flux recovery for $ \mathcal{Q}_k $ finite element of a scalar coefficient diffusion equation on quadtree meshes, with no restriction on the irregularities of hanging nodes. The construction requires no specific ad hoc tweaking for hanging nodes on $ l $-irregular ($ l\geq 2 $) meshes thanks to the adoption of virtual element families. The rectangular elements with hanging nodes are treated as polygons as in the flux recovery context. An efficient a posteriori error estimator is then constructed based on the recovered flux, and its reliability is proved under common assumptions, both of which are further verified in numerics.
On blowup of secant varieties of curves

In this paper, we show that for a nonsingular projective curve and a positive integer $ k $, the $ k $-th secant bundle is the blowup of the $ k $-th secant variety along the $ (k-1) $-th secant variety. This answers a question raised in the recent paper of the authors on secant varieties of curves.
