A New Member of the Milky Way’s Family Tree: Characterizing the Pontus Merger of Our Galaxy
Authors: Malhan Khyati 
Published: May 2022

Abstract
We study the Pontus structure—a recently discovered merger that brought in ∼7 globular clusters in the course of the hierarchical buildup of the Milky Way’s halo. Here, we analyze the stellar population of Pontus and examine (1) its phase-space distribution using the ESA/Gaia data set, (2) its metallicity and chemical abundances (i.e., [Fe/H], [α/Fe], [Mg/Fe], and [Al/Fe]) using the spectroscopic catalog of APOGEE DR17, and (3) the color–magnitude diagram that shows interesting features, including a possibly double horizontal branch and a small population of blue stragglers. In sum, the Pontus stars show some unique properties that suggest they likely originated from the merging of an independent satellite galaxy; however, future analysis will shed more light on the true nature of this structure. This chemodynamical analysis of Pontus stars is another step forward in our bigger quest to characterize all the merging events of our Milky Way.
Detection of Stellar-like Abundance Anomalies in the Slow Solar Wind

Abstract
The elemental composition of the Sun’s hot atmosphere, the corona, shows a distinctive pattern that is different from the underlying surface or photosphere. Elements that are easy to ionize in the chromosphere are enhanced in abundance in the corona compared to their photospheric values. A similar pattern of behavior is often observed in the slow-speed (<500 km s−1) solar wind and in solar-like stellar coronae, while a reversed effect is seen in M dwarfs. Studies of the inverse effect have been hampered in the past because only unresolved (point-source) spectroscopic data were available for these stellar targets. Here we report the discovery of several inverse events observed in situ in the slow solar wind using particle-counting techniques. These very rare events all occur during periods of high solar activity that mimic conditions more widespread on M dwarfs. The detections allow a new way of connecting the slow wind to its solar source and are broadly consistent with theoretical models of abundance variations due to chromospheric fast-mode waves with amplitudes of 8–10 km s−1, sufficient to accelerate the solar wind. The results imply that M-dwarf winds are dominated by plasma depleted in easily ionized elements and lend credence to previous spectroscopic measurements.
Creators and spectators facing online information disorder. Effects of digital content production on information skills

Published: May 2022

Misinformation on social media is a major problem facing our society. The experience deriving from use does not guarantee success in identifying false information. This study seeks to determine whether an active role in social media impacts on informational skills. For this purpose, we designed a survey that was administered to 756 young people between 16 and 26 years of age from different educational levels. The results show a profile of creative users who participate in generating their own content and sharing their recommendations openly, as opposed to another profile, the “spectators”, focused on entertainment and interaction. The creator profile is the variable that most contributes to reporting fake news on social media. When contrasting information, educational level is the most relevant aspect, although academic results and creator users also represent a significant contribution. Greater trust in the sources found on social media identifies the active profile, while distrust is associated with the spectators. We recommend that media education puts in place actions intended to recuperate trust in social media, so that they can be utilized critically, encouraging active, not reactive use.
La desinformación en las redes sociales es un problema al que se enfrenta nuestra sociedad. La experiencia de uso no garantiza el éxito para identificar la información falsa. El estudio pretende determinar si un rol activo en los medios sociales influye en las competencias informacionales. Para ello se diseñó una encuesta que se aplicó a 756 jóvenes entre 16 y 26 años de diversos niveles educativos. Los resultados muestran un perfil de usuarios «creadores» que participan en la generación de contenidos propios y en compartir sus recomendaciones abiertamente, frente a otro, los «espectadores», centrados en el entretenimiento y la interacción. El perfil creador es la variable que más contribuye a denunciar noticias falsas en las redes sociales. A la hora de contrastar la información, el nivel educativo es el aspecto más relevante, aunque los resultados académicos y los usuarios creadores también suponen una aportación significativa. Una mayor confianza en las fuentes presentes en las redes sociales distingue al perfil activo, mientras que la desconfianza está asociada con los espectadores. Desde la educación mediática se recomienda emprender acciones destinadas a recuperar la confianza en los medios sociales para que puedan ser utilizados de modo crítico, favoreciendo un uso activo y no reactivo de los mismos.
Unraveling disinformation: Notions and discourses from the Spanish population

Published: May 2022

Disinformation has become a core concept in communications research, related to media, technological and political phenomena that complexify its definition and diagnosis. Although its approach has been mainly quantitative, focus groups have also been used to understand the perception of the audience of this particular issue. This research is part of this second group of studies, and attempts to investigate the notions and discourses on disinformation in the case of Spain. For this purpose, seven discussion groups were conducted, with a structural sample constructed according to employment situation, ideology and age. The results show a perception of the communicative ecosystem structured in two chronological poles, which contrasts a past of reduced information supply – associated with traditional media – with a current informational environment where there is more media diversity, but also less trust in them. The groups point to the overabundance of information and associated disinformation with decontextualisation, low-quality journalism and the economic and political interests of different actors. Discourses outline a scenario of decline in journalism and the public sphere, which is perceived as polarised and emotional. Disinformation is therefore perceived as a multidimensional phenomenon that is associated with issues of major democratic transcendence rather than merely sending hoaxes through the Internet.
La desinformación se ha convertido en un concepto central en las investigaciones en comunicación, relacionado con diversos fenómenos mediáticos, tecnológicos y políticos que complejizan su definición y diagnóstico. Si bien su abordaje ha sido eminentemente cuantitativo, los grupos de discusión han sido también empleados para conocer la percepción de la audiencia sobre este fenómeno. Esta investigación se sitúa en esta estela, para tratar de indagar en las nociones y discursos que existen sobre la desinformación en el caso español. Para ello, se realizan siete grupos de discusión, con una muestra estructural construida según la situación laboral, la ideología y la edad. Los resultados muestran una percepción del ecosistema comunicativo estructurada en dos polos cronológicos, que contrapone un pasado de menor oferta informativa, asociado con los medios de comunicación tradicionales, a un entorno informacional actual donde existe más diversidad mediática, pero también menos confianza en los medios. Los grupos señalan la sobreabundancia de información, y vinculan la desinformación con la descontextualización, el periodismo de baja calidad y los intereses económicos y políticos de diversos actores. Los discursos delinean un panorama de declive del periodismo y de la esfera pública, que se percibe como polarizada y emocional. La desinformación se percibe, por lo tanto, como un fenómeno multidimensional que se asocia a cuestiones de mayor trascendencia democrática que el envío de bulos a través de Internet.

Le triomphe du rire sur la philosophie
Authors: Devillairs Laurence 
Published: May 2022

Depuis quatre cents ans, Molière fait rire. De qui rit-on ? Des dévots, des avares, des hommes, des femmes, des nobles, des bourgeois, de tout ce que l’homme compte de ridicule, de vaniteux et de lâche, de tout ce qui nous fait courir et désirer sans relâche. Molière ne nie pas le tragique de nos existences, mais prend le parti d’en rire. La lucidité, chez lui, est joyeuse. C’est une philosophie que délivre le comique, plus puissante, plus vraie que celle des philosophes des universités et des penseurs de salons.
Rencontres, retrouvailles, coup de foudre et nostalgie
Authors: Woscoboinik-Scheimberg Nora , Golse Bernard 
Published: May 2022

Après avoir évoqué les phénomènes de la rencontre, du coup de foudre et des retrouvailles, les auteurs proposent alors de considérer la rencontre sous l’angle d’un surgissement d’une représentation du lien à l’objet. Le concept de représentation d’objet mérite en effet aujourd’hui d’être décondensé en représentation de la place de l’objet, en représentation des liens à l’objet et en représentation enfin de l’objet en tant que tel, niveaux représentationnels qui s’instaurent sans doute successivement au cours du développement précoce. Après quoi, c’est la place du temps et du deuil au sein des rencontres et des retrouvailles qui se trouve abordé avant que soit envisagé le concept « d’Amour fou » d’André Breton à la lumière du concept « d’objet décevant » étudié par René Roussillon.
La domination touristique

Published: May 2022

La triple quête d’une authenticité ethnique imaginaire, de rapports de genre différenciés et d’un exotisme érotisé opère comme l’un des principaux moteurs de la hausse du tourisme occidental en Amérique latine et dans les Caraïbes. Y aborder le phénomène touristique comme un rapport social revient à mettre au jour les différentes formes de domination – entre opérateurs, visiteurs et visités – qui le constituent et le renouvellent.
La domination touristique

Published: May 2022

Considéré comme « moteur de développement » durant la Guerre froide, le tourisme est présenté aujourd’hui comme outil d’appoint ou de lutte contre la pauvreté. Or, aussi « doux » annonce-t-il désormais être – durable, éthique, responsable, etc. –, force est de reconnaître qu’en dépit des recommandations de l’OMT et de pays comme le Maroc, il a surtout perpétué un rapport néocolonial entre les pays émetteurs de touristes et l’Afrique.
La domination touristique

Mus par des objectifs de rentabilité financière immédiate, les opérateurs, publics et privés, du développement touristique de Saly sur la « Petite Côte » sénégalaise – première station balnéaire d’Afrique subsaharienne – ont sous-estimé les dégâts environnementaux, culturels et économiques occasionnés. Le littoral, écosystème fragile, et les populations locales, agriculteurs et pêcheurs, en ont fait les frais. Appel à une redéfinition du modèle.
Morts sans monde
Authors: Wiel Véronique 
Published: May 2022

Réfléchir à la « mort dérobée » en ces temps de pandémie nous impose de scruter plus largement ce qu’il en est du « traitement » moderne de la mort et d’y reconnaître tous les signes d’une « dé-mondanisation », d’une néantisation qui laisse les morts sans monde. Une telle destitution demande à être éclairée par une autre : celle de la vie, ou plutôt celle de « l’exception humaine » en ce domaine. Ce n’est pas seulement l’incapacité ou le refus de la saisir autrement qu’à son niveau biologique qui en cause ; ce sont aussi un langage, des pratiques nouvelles relevant d’un système de délégations ou de substitutions généralisé qui au total réifient les vivants – et les morts.
S’ouvrir à l’« autre croyant » : conditions et fruits d’une exigence théologique
Authors: Vivier-Muresan Anne-Sophie 
Published: May 2022

L’ouverture sur l’altérité religieuse constitue un rendez-vous incontournable de toute élaboration théologique. Nous en montrons ici les modalités en prenant appui sur l’expérience du dialogue interreligieux et du dialogue œcuménique. Après une brève introduction biblique mettant en perspective le rôle structurant de l’altérité dans le projet de Dieu, nous commençons par souligner les moyens à prendre pour échapper à la tentation bien réelle et souvent inconsciente d’instrumentaliser l’altérité rencontrée. Dans un troisième temps, nous présentons les fruits de cette ouverture, en les rassemblant essentiellement sous les termes d’une appréhension plus adéquate du réel, nous menant à une théologie elle-même plus ajustée. Pour ce faire, nous proposons de prendre pour posture de référence la démarche de la « théologie comparative ».

Published: May 2022

AbstractWe provide a thorough historical account of the genusPolleniaRobineau-Desvoidy, 1830 (Diptera: Polleniidae) in North America through published records beginning in 1849. From this, we have gleaned insights into their presence on this continent, how they were perceived as pests, and studies of their biology to better frame current work on this genus. Further, we report on our own study ofPolleniaspp. distribution across Canada from our collection of 2211 specimens that include all six North American species collected in seven provinces between 2011 and 2013. We report first provincial records forPollenia angustigenaWainwright, 1940 andP. labialisRobineau-Desvoidy, 1863. We also discuss knowledge gaps and provide suggestions for future research.
Knowledge, Attitude and Practices Related to Tuberculosis among Students in a Public University in East Coast Malaysia
Authors: Mohd Izham Mira Nadiah , Rahman Nor Azlina , Haque Mainul 
Published: May 2022

Background:
Tuberculosis (TB), better known as TB, is one of the infectious diseases that can cause death and therefore gains major public concerns worldwide. This study attempts to assess the knowledge, attitude and practice (KAP) related to TB among the students in a public university and find the association between the KAP with demographic factors and between the KAP themselves.

Materials and Methods:
Self-administered questionnaires were distributed to 200 students from the six faculties in the university for the data collection and analysis in this cross-sectional study. The questionnaire was divided into four parts: Demographic characteristics, knowledge, and attitude toward TB, and practices toward the prevention and control of TB.

Results:
The findings showed that most students had a moderate level of knowledge (obtained 47–92 out of the total 138 marks) and practice (obtained 29–57 out of the total 86 marks) and a good attitude related to TB (obtained 20–28 out of the total 28 marks). There were no significant differences in the level of KAP scores between the different genders, ages and years of study among the participants. However, a significant result was found between the KAP level of the various faculties (P < 0.001, <0.001 and 0.027, respectively), with the students from the Faculty of Medicine having the highest KAP level compared to others.

Conclusion:
This study also portrayed that higher knowledge was associated with a higher attitude and practice towards TB (P < 0.001 and 0.045, respectively). Based on the findings, the study proposes more health education programs to promote the awareness on early prevention of TB to achieve an improved level of KAP in controlling and preventing TB infection.
Bilateral Massive Complex Composite Odontoma of the Mandible: A Rare Case Report
Authors: Singh Priyankar , Iqbal Jawed , Imam Zeenat S. , Biswas Krishna P. , Singh Nimmi , Mishra Navin 
Published: May 2022

Rationale
Odontomas result from abnormal growth of differentiated epithelial and mesenchymal cells, which form ameloblasts and odontoblasts along with pulp tissue at times.

Patient Concerns
A patient reported with a chief complaint of hard swelling of the lower jaw causing difficulty in mouth opening and facial deformity.

Diagnosis
A provisional diagnosis of complex odontome based on clinicoradiological findings was made, which was later confirmed as complex composite odontome histologically.

Treatment
Bilateral hard tissue mass was surgically removed from the mandible with utmost precaution to prevent jaw deformity. On fine separation, the specimen yielded nearly 82 small teeth-like structures.

Outcomes
Histopathologically, multiple small teeth-like structures with haphazardly arranged central fibrofatty pulpal stroma surrounded by well-formed dentinal tubules and empty areas representing decalcified enamel matrix surrounded by fibrovascular stroma at the periphery were seen.

Take-away Lessons
Early diagnosis and treatment ensures minimal surrounding deformities, better prognosis, and less chances of recurrence.
Cranio-cervical posture and rapid palatal expansion therapy
Authors: Serritella Emanuela , Impellizzeri Alessandra , Musone Ludovica , De Stefano Adriana Assunta , Gabriella Galluccio 
Published: May 2022

Objective:
Connections between craniocervical posture (CCP) and changes in teeth position have already been demonstrated; however, the defined pathway of relationship is still not clear. The aim of this study was to evaluate CCP modifications after rapid maxillary expansion therapy using rapid palatal expansion therapy (REP)/McNamara appliances.

Materials and Methods:
A consecutive series of 35 subjects, aged between 6 and 14 years, with no prior history of orthodontic treatment, and requiring skeletal expansion of the upper arch, were selected and analyzed. All patients were treated with REP or Mcnamara appliance: the active phase of 15 days and retaining phase of 6 months. Cephalometric analysis was carried out before (T0) and after (T1) orthodontic therapy evaluating changes in the craniofacial area and those related to CCP. The obtained data were statistically analyzed for the pre-post changes.

Results:
No statistically significant difference emerged indicating a modification in the CCP measured at T0 and T1 (P > 0.05). Patients treated with the McNamara appliance, compared to those treated with REP, showed a higher value of the angle OPT ^ Ver (P = 0.021), and a lower measure of the angles CVT^EVT (P = 0.035) and EVT^Ver (P = 0.023). Furthermore, patients treated with REP showed a higher hyoid angle value than those treated with McNamara (P = 0.047).

Conclusion:
This study did not reveal any relationship between the application of palatal expansion therapy and changes in CCP.
Bone-anchored maxillary protraction (BAMP)
Authors: Kamath Apoorva , Sudhakar Shetty Suhani , Kannan Greeshma , Rai Kripal , SB Athul 
Published: May 2022

INTRODUCTION:
Protraction therapy for maxillary deficiency in the treatment of skeletal class III malocclusion involves the use of facemask. Conventionally facemask has been anchored to the maxillary dentition, which is responsible for some of the counter-productive effects of facemask therapy including backward and downward rotation of the chin, increase in the lower anterior facial height, proclination of maxillary incisors, retroclination of mandibular incisors apart from mesialization of maxillary molars with extrusion and decreased overbite.

AIM:
The aim of this article is to highlight the nuances of Bone-Anchored Maxillary Protraction (BAMP) including a literature review, which is comprehensive and narrative and comparing the different techniques involved such as type 1 BAMP versus type 2 BAMP and BAMP versus facemask.

MATERIALS AND METHODS:
A computerized search was performed in electronic databases such as PubMed, PubMed Central, Cochrane, Embase, DOAJ, and Google scholar using key words such as “bone-anchored maxillary protraction” and “BAMP.” The search was confined to articles in English published till March 2021. Forty-seven case-controlled, cross-sectional, retrospective and prospective studies, as well as systematic reviews and meta-analysis were included in this article, which were limited to human subjects. A hand search of the reference lists of the included articles was also carried out to include missed out articles.

CONCLUSION:
To overcome these drawbacks, BAMP was introduced, which causes both maxillary protraction, restraint of mandibular growth with minimal dentoalveolar changes. BAMP is used widely nowadays in the treatment of skeletal class III malocclusion.
Ion release and surface roughness of silver soldered bands with two different polishing methods
Authors: da Silveira Ramiro Estacia , Gonçalves Tatiana Siqueira , de Souza Schacher Helena Reis , de Menezes Luciane Macedo 
Published: May 2022

OBJECTIVE:
To evaluate the surface roughness and ion release of silver-soldered joints by using two polishing methods.

METHODS:
174 orthodontic bands with and without silver-soldered joints were evaluated and divided into three groups: two experimental, with different polishing methods (SP1 and SP2), and one control (SS) composed of bands without silver solder. For ionic release, 50 bands of each group were immersed in saline solution and submitted to atomic absorption spectrophotometry to quantify the amount of Fe, Ni, Cr (in all the three groups), Ag, Cu, Cd, and Zn (in the two experimental groups). A rugosimeter was employed to verify the surface roughness.

RESULTS:
Ni and Cr were released in higher amounts after soldering. Cd, Ag, Zn, and Cu may be released from silver-soldered bands independently of the polishing method employed. Ag was released in higher amounts from the soldered bands that presented higher surface roughness.

CONCLUSIONS:
Differences exist in relation to the surface roughness of silver-soldered bands when distinct polishing methods are used. Toxic ions may be released from silver soldered joints and higher surface roughness may cause higher ionic release.
