Acoustic communication in insect disease vectors
No full textAcoustic signalling has been extensively studied in insect species, which has led to a better understanding of sexual communication, sexual selection and modes of speciation. The significance of acoustic signals for a blood-sucking insect was first reported in the XIX century by Christopher Johnston, studying the hearing organs of mosquitoes, but has received relatively little attention in other disease vectors until recently. Acoustic signals are often associated with mating behaviour and sexual selection and changes in signalling can lead to rapid evolutionary divergence and may ultimately contribute to the process of speciation. Songs can also have implications for the success of novel methods of disease control such as determining the mating competitiveness of modified insects used for mass-release control programs. Species-specific sound "signatures" may help identify incipient species within species complexes that may be of epidemiological significance, e. g. of higher vectorial capacity, thereby enabling the application of more focussed control measures to optimise the reduction of pathogen transmission. Although the study of acoustic communication in insect vectors has been relatively limited, this review of research demonstrates their value as models for understanding both the functional and evolutionary significance of acoustic communication in insects.Peer reviewe
Lo que logra El Feliz Ingenio Neomexicano : Felipe M. Chacón and Poesía y prosa
No full textEl feliz ingenio neomexicano (UNM Press 2021) is a bilingual recovery edition of Obras de Felipe Maximiliano Chacón, el Cantor Neomexicano: Poesía y prosa, the first collection of poetry published by a Mexican American author. Journalist and author Felipe M. Chacón, part of a distinguished and active family of nuevomexicano authors, published the book in Albuquerque in 1924, on the presses of the bilingual newspaper La bandera americana. El feliz ingenio neomexicano (that “inspired New Mexican wit”) reestablishes Chacón’s work and his reputation by making the text widely available to readers for the first time in nearly a century. In this talk, Dr. Anna M. Nogar and Dr. A Gabriel Meléndez discuss the enduring legacy of Felipe M. Chacón\u27s deeply bilingual writing, created and shared during New Mexico\u27s fraught 19th and early 20th centuries.Anna M. Nogar is Professor in the University of New Mexico’s Department of Spanish and Portuguese. She is the author, editor, and coeditor of several books, including Quill and Cross in the Borderlands: Sor María de Ágreda and the Lady in Blue, 1628 to the Present; A History of Mexican Literature; and Sisters in Blue: Sor María de Ágreda Comes to New Mexico / Hermanas de Azul: Sor María de Ágreda viene a Nuevo México (UNM Press).A. Gabriel Meléndez is a Distinguished University Professor and the former director of the Center for Regional Studies at the University of New Mexico. Meléndez is the author, editor, and co-editor of numerous books, including The Book of Archives and Other Stories from the Mora Valley, New Mexico; Santa Fe Nativa: A Collection of Nuevomexicano Writing (UNM Press); and The Writings of Eusebio Chacón (UNM Press).https://digitalrepository.unm.edu/laii_events/1144/thumbnail.jp

Corrigendum: Some class sizes conditions implying solvability of finite groups

Precisely, in the proof of Step 1 we suppose that there exists a p-element x of index m
where p is the set of primes dividing m and we have the following situation: CGðxÞ
is a direct product of a p-subgroup and a p0
-subgroup and the class sizes of such
p0
-subgroup are at most two numbers: 1 or n. However, the case in which all of them
are exactly equal to 1, that is, when the p0

The square as the epicenter of local development
No full textThere is no denying that the capital has penetrated too deep and far away in body and soul of the people, in their intelligence, psyche and imagination, in their core of 'vitality'; and while such 'vitality' has become the primary source of value in capitalism. In addition to this, the dramatic centralization of political and economic power that characterizes our way of organizing society leads, ultimately, a deep divorce between the citizen’s requirements and the content of economic and social development. The local empowerment emerges as a new way to aggregate, create meaning, invent devices for appreciation and self-respect; and also an important tool that can facilitate the organized expression of community needs and assist in setting democratic priorities of local development. There is no doubt that something new is emerging in various parts of the territory in Sao Paulo – the biggest city of Brazil, with over eleven billion people. It is remarkable that there is a growing desire and political will of the inhabitants to relinquish their passive attitudes and assume, collectively, the changes in favor of the creation of improved living conditions of the neighborhood. In an area comprising four neighborhoods of the west Sao Paulo it was identified three social experiences that follows singular paths, but have the same goal: promoting the improvement of the square nearby their homes and, thereby, encourage the use of public space. The aim of this report is to analyze these three social experiences and compare them with the concept of local development. To support this essay, it was made a literature review on the concept of Development and Local Development based, fundamentally, on the ideas of Amartya Sen, Ladislau Dowbor, Ignacy Sachs, Celso Furtado and Alain Lipietz. The author of this essay participated actively in the three social experiments from February to December 2010 producing 'thick descriptions' (GEERTZ, 1989) about the meetings, the dynamics of neighborhoods and squares and informal conversations with participants. This essay concludes that the square in the urban territory can symbolize the epicenter of local development. Key words: social experiences; square; local empowerment; local development.
Interview with Juan Felipe Herrera
No full textIn this interview, Juan Felipe Herrera highlights the influence of the Chicano/ Latinx movement in the early 1970s and how it sparked a sense of cultural freedom, particularly in various forms of expression such as writing, visual art, murals, performance, and public speaking. The individuals involved in this movement were not only bilingual but also quadrilingual, incorporating additional languages such as Caló, Aztec, Maya, and Pachuko talk. The origins of code-switching are attributed to sociological factors, as it involves navigating between different speech communities, and a growing awareness of language rights and historical roots across the hemisphere. The author also discusses Mary Douglas' viewpoint on the relationship between the center (represented by the nation) and its margins (referring to the border). According to Douglas, the center seeks to protect itself from potential threats and "contamination" posed by trespassers, a narrative regarding social progress and decline assumed by early 19th-century anthropologists and religious beliefs of the European priest classes of the Spanish encounter in their mission of religious conversion of Mesoamerican indigenous peoples in 1519 forward, therefore considering them dangerous and impure. Against such imposition of a center, new feminist anthropologists, in the wake of Anzaldúa and other authors are mapping new ideas about "borders," with notions such as dynamic "radical space." The concept of totality lies at the core of every artistic expression and existence. It cannot be grasped as a physical object or possession. Instead, it resembles a boundless and permeable Quantum Sphere. This profound connection can be observed between a Tzotzil-Tzeltal Mayan weaver woman adorning a Huipil garment and the ancient narratives of how the universe was created. Finally, Juan Felipe Herrera states that nowadays we live in a Lorquian time, characterized by "persecution, screams, and dream." Fortunately, there are sources of hope: "a light and moon and a ready horse and a nightrider in between destruction and old structures of society."234227Series: Estudios hispánicos en el contexto global.

Acoustic signals in the sand fly <it>Lutzomyia (Nyssomyia) intermedia </it>(Diptera: Psychodidae)
No full textAbstract Background Acoustic signals are part of the courtship of many insects and they often act as species-specific signals that are important in the reproductive isolation of closely related species. Here we report the courtship songs of the sand fly Lutzomyia (Nyssomyia) intermedia, one of the main vectors of cutaneous leishmaniasis in Brazil. Findings Recordings were performed using insects from three localities from Eastern Brazil: Posse and Jacarepaguá in Rio de Janeiro State and Corte de Pedra in Bahia State. The three areas have remnants of the Brazilian Atlantic forest, they are endemic for cutaneous leishmaniasis and L. intermedia is the predominant sand fly species. We observed that during courtship L. intermedia males from all populations produced pulse songs consisting of short trains. No significant differences in song parameters were observed between the males of the three localities. Conclusions L. intermedia males produce acoustic signals as reported for some other sand flies such as the sibling species of the Lutzomyia longipalpis complex. The lack of differences between the males from the three localities is consistent with previous molecular studies of the period gene carried out in the same populations, reinforcing the idea that L. intermedia is not a species complex in the studied areas and that the three populations are likely to have similar vectorial capacities.</p
On zeros of irreducible characters lying in a normal subgroup
No full text[EN] Let N be a normal subgroup of a finite group G. In this paper, we consider the elements g of N such that x(g)¿0 for all irreducible characters x of G. Such an element is said to be non-vanishing in G. Let p be a prime. If all p-elements of N satisfy the previous property, then we prove that N has a normal Sylow p-subgroup. As a consequence, we also study certain arithmetical properties of the G-conjugacy class sizes of the elements of N which are zeros of some irreducible character of G. In particular, if N=G, then new contributions are obtained.The first author is supported by Proyecto Prometeo II/2015/011, Generalitat Valenciana (Spain).
