Authors: Salas Medina Daniela Lizbeth , Medina Barragán Ramona Armida , Mercado Rivas Martha Xitlali , Valle Solís Martha Ofelia
Published: April 2024

Los Objetivos de Desarrollo Sostenible (ODS), conocidos también como la Agenda 2030, son 17 objetivos globales interconectados diseñados como un plan para lograr un futuro mejor y más sostenible. La investigación es parte crucial para generar estrategias que permitan fomentar la educación de calidad, salud y bienestar, igualdad de género, reducción de las desigualdades, entre otros. Sin embargo, a pesar de las convocatorias a nivel superior para realizar estancias de investigación, es poco el interés mostrado en los estudiantes; particularmente en Enfermería, la apatía por involucrarse en los grupos de investigación y cuerpos académicos es notoria, por lo que es importante comprender de donde viene esta actitud de no generar conocimiento. El objetivo de esta investigación fue identificar los factores que influyen en la indiferencia a la investigación en los estudiantes de Enfermería; se hizo un diseño descriptivo y transversal, aplicando un instrumento de 10 preguntas de opción múltiple. En los resultados se observó que los factores principales por los que no se interesan en la investigación son económicos, burocráticos, poca difusión y considerar que es difícil el arte de generar conocimientos. Es claro que los investigadores que son parte de las instituciones de nivel superior están fallando en clarificar y fomentar el espíritu de curiosidad en los estudiantes.

Authors: Kavitha M. , Kumar Dr. A. John Sanjeev
Published: April 2024

Movie goers use Twitter and other websites to share their thoughts and feelings regarding Tamil films in this age of social networking and online interaction. It is essential to examine these feelings for realizing the responses of the public and assess a film's level of success. In this research, a novel contextual-cognitive convolutional attentive long/short-term memory (C3-ALSTM) strategy for assessing Tamil movie reviews via Tamil tweets is presented. We first gather the Tamil movie review dataset through an open database to assess the suggested C3-ALSTM approach. We normalize the gathered data by eliminating extraneous information, noise and redundant data. Tokenization and the removal of stop words and special characters are employed in this phase. Following data cleansing, term frequency-inverse document frequency (TF-IDF) is applied for extracting the attributes. The suggested approach evaluates the Tamil reviews based on these retrieved features. The suggested approach is put into practice using the Python platform and its accuracy, precision, recall and f-measure metrics are examined. According to the research's findings, the suggested method outperforms other used techniques for sentiment assessment of Tamil reviews. In addition, this research attempts to offer insightful information about how the public reacts to particular Tamil films, advancing knowledge of public preferences and attitudes toward the Tamil cinema industry.

Effect of Dynamic Wind Load on Tall Structure Using Gust Factor Method
Authors: MALI AMIT K , Patel Vishalkumar B. , Desai Atul N.
Published: April 2024

With advancements in construction materials and design technologies, as well as the context of substantial urban growth, tall structures are increasing day by day, and the cost of land is also rising. Hence, constructing tall structures is the best way to expand vertically. In this study, shear force and bending moment multipliers were calculated using MATLAB for 155,040 data samples. The main objective of the paper was to investigate the effect of the gust factor on a 100m tall structure, while keeping the B/H ratio between 0.2 and 1.2 and the L/B ratio of the building varying from 0 to 50. The height of the structure was varied from 50m to 450m to analyze the shear force and bending moment multipliers. Furthermore, the study aimed to examine the effect of the fundamental frequency of the building structure on the gust factor and to prepare elastic spectra accordingly.

As the slenderness ratio increases, the gust factor also increases. The gust factor for flexible structures was higher than that for stiff buildings. The elastic spectra revealed that with an increase in frequency, the gust factor decreases, and at a certain frequency value, it becomes constant. The current study utilized shear force and bending moment multipliers, as well as the elastic spectra of gust, to calculate shear force and bending moment. This method proved to be quicker than manual calculations. The shear force and bending moment obtained from the present study were compared to those from IS 875:2015, and the error was found to be smaller than 10%.

Passages du net au flou
Authors: Martin Pascal
Published: April 2024

La profondeur de champ peut être définie comme la zone de tolérance où l’œil ne peut pas faire la différence entre le flou et le net. Autrement dit, elle n’est autre qu’un espace flou qui est vu net. La mise au point, qui a une fonction essentielle au cinéma, est donc tout autant un enjeu de perception que de technologies de prise de vues. Dans le cadre de cette publication, les conséquences théoriques et pratiques d’un tel constat seront explorées tant du point de vue des chercheurs que de celui des praticiens. Les enjeux liés aux conditions de la prise de vues seront étudiés en relation avec la mesure de la profondeur de champ et les aspects esthétiques associés à ces variables techniques et perceptives.

Published: April 2024

Les machines produites sous le sigle Bolex par l’entreprise suisse Paillard ont leur histoire propre, qui les place dans un héritage local riche et complexe : celui de la mécanique de précision, de l’industrie horlogère et musicale. Une caméra en particulier fut l’emblème de la marque et est, encore aujourd’hui, l’un des appareils les plus célèbres de l’histoire du cinéma : la Bolex H16, destinée à l’amateur exigeant. Il s’agira ici d’interroger la caméra selon trois axes principaux : sa mécanique interne, replacée dans le contexte industriel de sa conception et de sa fabrication; la gestuelle particulière que la forme de la machine engage chez la personne qui l'opère; et enfin, la façon dont ces éléments se répercutent sur la diversité des usages sociaux.
Main d’acier dans un gant de velours
Authors: Bouniol Judith
Published: April 2024

À travers la Roumanie, les ressources naturelles attisent la cupidité et attirent d’énormes investissements. Ce phénomène est tapi derrière l’image idyllique de l’adhésion de la Roumanie à l’UE. Toutefois, cette apparente légalité est en fait un gant de velours cachant l’agressivité de la main de fer à l’origine du phénomène. Les terres et ressources naturelles sont saisies en masse par quelques acteurs monopolisant le contrôle des bénéfices de leur exploitation ainsi que la capacité de décision sur leur utilisation. Les activités développées ne sont de toute évidence pas une forme d’investissement qui répond aux besoins actuels des territoires ruraux roumains.

Le sort des petits producteurs reste compromis, à l’heure où s’exercent de nouvelles pressions sur les terres. Promue par les institutions internationales, la « cohabitation harmonieuse » entre agrobusiness et agricultures paysannes ne change pas la donne. Les fameux scénarios « gagnant-gagnant » de la Banque Mondiale sont illusoires. Plus que jamais une réforme en profondeur du système agricole et alimentaire international axée en priorité sur le renforcement des agricultures paysannes et la reconnaissance du rôle central joué par les paysans dans la lutte contre la faim s’impose. Elle ne pourra que s’appuyer sur une approche fondée sur le droit et des politiques adaptées aux contextes locaux, garantissant l’accès à la terre et assurant la protection des paysans face aux marchés internationaux.
Réviser les investissements fonciers en Europe grâce aux Directives sur la Gouvernance Foncière
Authors: Kroff Florence , Seufert Philip , Guffens Claire
Published: April 2024

En dépit de l’idée répandue parmi les gouvernements, l’Europe n’est pas exempt non plus de problèmes liés aux régimes fonciers des terres et des ressources naturelles. Reconcentration croissante des terres agricoles, accaparements et manque d’accès aux terres sont autant de dynamiques favorisées par les politiques d’investissements fonciers actuelles. Cet article est un plaidoyer pour réviser les investissements fonciers en Europe, se guidant avec les Directives sur la Gouvernance Foncière de la FAO.

« Des Sauvages, ou Voyage, mai 1603 »
Authors: De Champlain Samuel
Published: April 2024

De 1599-1601, le jeune Samuel Champlain est assigné par le roi Henri IV pour une mission d’espionnage en Nouvelle-Espagne (Antilles). S’opposant à ce qu’il avait vu du traitement des Indiens par les Espagnols, dont il méprisait les visées, « il s’est montré un observateur très attentif, et ce qu’il a vu a marqué profondément sa pensée. Le séjour de Champlain en Nouvelle-Espagne a influencé durablement sa carrière en Nouvelle-France. Il en est ressorti avec l’idée nouvelle d’un empire ou Indiens et Européens pourraient vivre ensemble dans un esprit différent. » Ainsi le mot « Sauvages », avec un S majuscule et au pluriel, a beaucoup changé dans sa définition, dans sa connotation et dans sa perception au cours des siècles. On voit ici, dans ce magnifique texte aux origines du lien entre Français et Autochtones, tout le respect que Champlain avait pour ces peuples de la forêt, acception d’origine du mot « Sauvages ».

Anahad Naad and Pictorial Resonance: The Halo and Sonic Vibration in Sikh Art
Authors: Bhogal Gurminder Kaur
Published: April 2024

The halo is a familiar symbol across Buddhist, Christian, and Mughal art, but its role in Sikh visual media has yet to be acknowledged and examined. This article studies the Sikh halo in relation to key philosophical concepts of dasam dwar (the tenth door/opening, located at the crown of the head) and anahad naad (an embodied perception of an internally heard music). When viewed from a Sikh perspective, the halo emerges as an external marker of an internal attunement to the divine one. As spectators, we attune to the latent sonic frequencies of the halo, which reflect the spiritual attainment of Sikh Gurus and other holy figures. Sikh art allows the inner/outer dialectic of the halo to come into view: to our eyes, the halo signals spiritual realization, while to our ears, it invites us to contemplate the intensity of sonic vibration that resounds through and emits from the divine body in tandem with the expressive kirtan of Bhai Mardana and his rabab (a plucked chordophone).

Drawing on select artwork, I invite spectators to experience the sonic dimension through attention to the unique positioning of the halo in relation to the rabab. My critical focus on sonic vibration as suggested by a symbolic connection between the halo and anahad naad allows a concentration at the head to offer a new vantage point for understanding the iconographical presence of this symbol. This article centers Sikh art within the long history of the halo while highlighting how this symbol establishes a unique epistemological system of expressive meaning.
Representing Sikhs and Sikhi in Museum Spaces
Authors: Bainiwal Tejpaul Singh , Coulson Tauna
Published: April 2024

This paper provides a dual perspective on an exhibit of Sikh art from the Kapany Collection that was curated at the Eloise Pickard Smith Gallery at the University of California, Santa Cruz, from January to March 2022. The collection was donated to the Sikh Foundation International by Dr. Narinder Singh Kapany, a scientist, entrepreneur and art collector. The exhibit was a collaboration between the Foundation and the University, and was accompanied by an educational exhibit on the history of Sikhs in the United States, particularly California. This paper has two parts. First, Tauna Coulson, a professional art curator, describes her experiences of curating the exhibit. In the second part, Tejpaul Singh Bainiwal, co-founder of the Sikh American History Project, provides a broader perspective and analysis on the question of representing Sikhs and the Sikh tradition in museum spaces, along with a commentary on this particular effort.
Arpana Caur and the Mending of Religious Fractures
Authors: Lucy Soucek
Published: April 2024

This paper explores the paintings of Sikh artist Arpana Caur. She creates works of art that draw upon motifs from different religions to foster unique interfaith spaces. Her bold and bright strokes of color both illuminate memories of cultural trauma and celebrate religious dedication. She depicts powerful images of boundary and unity, love and harm, and violence and safety. Most of all, Caur’s paintings illustrate this vital theme: respect the beauty of difference.
Discovering stories from Punjab on the streets of Saint-Tropez, Cote D’Azur, France
Authors: Singh Ranveer (Rav)
Published: April 2024

This paper presents stories associated with artefacts and episodes from the Kingdom of Lahore in Punjab, told through the author's research visit and fieldwork on the streets of Saint-Tropez located on the Cote D'Azur in the South of France. Episodes in the early 19th century that shaped the establishment of the Kingdom of Lahore, ruled by Maharajah Ranjit Singh, are outlined, and the author introduces Europeans employed in the armies of Punjab. The author describes how the actions of the Maharajah in the 1830s opened up highly profitable trading routes for some of his European generals between Lahore and Europe, dealing in arts, armour and textiles. The establishment of these Indo-French trading routes included the export of luxurious shawls from Kashmir and Amritsar (ruled at the time by Ranjit Singh) to Europe. One prominent individual, Jean-Francois Allard, who rose to become a general in Punjab, is chronicled, and the paper focuses on Allard and his wife, Bannou Pan Dei, and their life in Saint-Tropez. The paper ends by highlighting the recent work by officials in Saint-Tropez to articulate these stories and shared histories to develop interest, relations and promote tourism between the locations of India, especially Punjab and Himachal Pradesh, and France.
