Study on the Properties of LiTaSiO5-based Lithium Ion Conductors Doped by Acceptors
Authors: Ha Qi , Zou Qirui , Hu Xinyu , Wang Weiguo 
Published: February 2024

Lithium-ion conductor plays an important role in the all-solid-state batteries. In this paper, the novel sphene structure LiTaSiO5 lithium-ion conductor material was taken as the research object. The lithium ion concentration can be changed by the acceptor doping of titanium ions. And further, the electrical properties of LiTaSiO5 lithium-ion conductor can be enhanced. Through the AC impedance spectroscopy measurement, the ion conductivity of Li1.1Ta0.9Ti0.1SiO5 sample can reach 1.93×10-5 S/cm at 333 K, which is higher than that of the parent LiTaSiO5 material at the same conditions. Combined with the results of dielectric relaxation spectroscopy, the higher ionic conductivity may be derived from the higher mobile lithium ion concentration in the Li1.1Ta0.9Ti0.1SiO5 compound. The research results have very important theoretical value for the research and design of new sphene-structure lithium-ion conductors.
Advances and Challenges of Boiling Heat Transfer
Authors: L. Pioro Igor 
Published: February 2024

Boiling is a heat-transfer process during which vapor bubbles are created on a heated surface (nucleate boiling) or inside overheated liquid (bulk boiling). Boiling has been used by humans for tens of thousands of years for cooking, however, its application in industry started somewhere in the seventeenth century. Moreover, actual research into boiling-heat-transfer phenomena started only around 1920s. In general, several major types of boiling process can be identified: natural-convection pool boiling vs. forced-convection flow boiling and nucleate boiling vs. bulk boiling. Major nucleate-pool-boiling characteristics are as the following: Onset of Nucleate Boiling (ONB); Heat Transfer Coefficient (HTC); Critical Heat Flux (CHF); HTC at film pool boiling; minimum heat flux at film pool boiling; and HTC at transition boiling. Quite similar characteristics correspond to flow-boiling: Onset of subcooled Nucleate Boiling (ONB); Onset of Significant Void (OSV); HTC; CHF; and Post-DryOut (PDO) heat transfer. In spite of more than 100 years of active research and many years of applications, boiling phenomena/heat transfer are still not fully investigated and understood. There are some attempts to develop boiling-phenomena theories, but, unfortunately, they are not so practical yet. Therefore, more or less all practical calculations of various boiling characteristics/parameters rely heavily on empirical correlations, which were obtained experimentally. Due to this sophisticated studies are performed into boiling phenomena in the world.

Propeller and Engine Performance of Commercial Windships: Benefits and Trade-Offs
Authors: Reche-Vilanova Martina , Bingham Harry B. , Fluck Manuel , Morris Dale , Psaraftis Harilaos N. 
Published: February 2024

_
Wind propulsion systems (WPS) for commercial ships can be a key ingredient to achieving the IMO green targets. Most WPS installations will operate in conjunction with propellers and marine engines in a hybrid mode, which will affect their performance. The present paper presents the development of a generic, fast, and easy tool to predict the propeller and engine performance variation, along with the cost, as a function of the wind power installed in two operation conditions: fixed ship speed and constant shaft speed. Specific focus is directed toward showing generic trends and trade-offs that inform economic decision-making. To this end, a key feature of the presented work is the ability to assess the cost–benefit of both controllable pitch propellers and fixed pitch propellers (CPPs and FPPs). This provides advice on when, in terms of WPS installation size, it is worthwhile to install which kind of propeller. CPPs are found to be more suitable for newly built wind-powered ships (&gt;70% wind power), while a conventional FPP is satisfactory for wind-assisted ships (&lt;70% wind power) and retrofitted installations. The results for a 91,373 GT bulk carrier showed that a WPS unloads the propeller and the engine, which leads to an increase in the propulsive efficiency and a detrimental rise of the engine specific fuel oil consumption. However, propeller gains are found to be greater than engine losses, which result in extra savings. Thus, not only does a WPS save fuel and corresponding pollutant emissions, but it also increases the entire propulsive efficiency.

The Influence of Green Performance and Intellectual Capital on Tax Avoidance
Authors: Sailendra Sailendra 
Published: February 2024

The purpose of this study is to examine the influence of green performance and intellectual capital on tax avoidance, focusing on intellectual capital as a moderating variable. The research sample consists of 264 observations from 45 publicly listed groups of green companies (proper) on the Indonesia Stock Exchange from 2017 to 2022. The data were collected from the website of the Indonesian Stock Exchange (IDX), the Ministry of Environment and Forestry of the Republic of Indonesia, and the websites of the companies. The data were analyzed using structural equation modeling (SEM) to test the research hypotheses. The results of the hypothesis test indicate that environmental performance does not affect tax avoidance, but shows a negative relationship. Similarly, intellectual capital does not affect tax avoidance but also has a negative relationship. In addition, intellectual capital shows no moderating but negative directional sign between green performance and tax avoidance. The moderating function of intellectual capital reduces the tendency of tax avoidance in firms with high green performance. The results of this study suggest that intellectual capital strengthens environmentally and socially responsible behavior. Firms with lower intellectual capabilities tend to engage in tax avoidance practices. This research contributes to the literature on the drivers of corporate tax avoidance and sustainable practices, which can provide insights into how intellectual capital drives responsible tax compliance behavior in green companies. The results of this study have implications for corporate tax policy and motivate ethical behavior within the firm.

A preocupação em "inventar o Brasil", isto é, em descobrir as supostas raízes históricas do país, contidas na linha de continuidade dos eventos históricos, unindo presente e passado, encadeando os processos sociais, políticos e culturais marcou o horizonte de muitos intelectuais brasileiros, entre os anos vinte e trinta Envolvidos com a tarefa de determinar futuros possíveis, de encontrar as formas de superação dos obstáculos ao desenvolvimento social e econômico, perguntaram-se pelos traços que marcaram a cultura nacional, pelas características essenciais do "povo brasileiro", pelo passado que o havia constituído como tal. "Que país é este?" foi a questão a que procuraram responder em termos das interpretações das origens históricas do Brasil, da colonização à contemporaneidade. "Que país queremos que seja?" tem sido a pergunta colocada desde então, retomada em sucessivas ocasiões, inclusive agora, na era da globalização, em que se desfazem as antigas referências nacionais.
Las genealogías de Margot Glantz: del Génesis al Distrito Federal
Authors: Masterson Araceli 
Published: February 2024

La autobiografía como género literario ha recorrido un largo camino desde su definición más simple, como descripción que un individuo hace de su propia vida. El pacto autobiográfico de Philipe Lejeunne ha perdido vigencia en tanto que se cuestiona la relación entre los hechos de una vida y los procesos que influyen sobre la memoria y la construcción de recuerdos. James Olney insiste en que cualquier tipo de escritura, incluyendo la crítica literaria, puede considerarse autobiográfica, y Paul de Man, desde una posición ya post-estructuralista, afirma que lo autobiográfico no es en absoluto un género literario sino un recurso literario. En esta "crisis" de autorrepresentación del sujeto en la autobiografía, la crítica literaria ha pasado a enfocar el análisis de la autobiografía como acto de escribir, recordar, leer e interpretar. En este contexto surgen Las genealogías de Margo Glantz, en las que la autora mexicana se sirve de una estructura de carácter público para definir lo privado. La historia que presenta Glantz es activa, abierta a continuas posibilidades de renovación, repetida y repasada con el objetivo de afirmar su identidad como mujer judeomexicana ante el presente y hacia el futuro.

Surviving Mexico’s Dirty War: A Political Prisoner’s Memoir. ALBERTO ULLOA BORNEMANN: Edited and translated by Arthur Schmidt and Aurora Camacho de Schmidt. Philadelphia: Temple University Press, 2007.
Authors: Cohen Jeffrey H. 
Published: February 2024

Ulloa Bornemann has given us a gift in his memoir documenting how he survived Mexico's dirty war in the 1960s and 1970s. His gift is a sensitive, personal, profoundly moving account that opens the doors on the brutality and violence of the Mexican state, the goals of left wing civil movements and the role that one man plays. Ulloa Bornemann's book follows the model of a testimonial or testimonio - a rich traditional literary trope in Latin America - but at the same time it is much more.
Football in the Americas: Fútbol, Futebol, Soccer. RORY M. MILLER and LIZ CROLLEY (eds.): London: Institute for the Study of the Americas, 2007.
Authors: Karush Matthew B. 
Published: February 2024

Over the last several decades, football, the world's most popular sport, has begun to attract well-deserved attention from academics in a variety of disciplines. In general, this scholarship has fallen into two unrelated fields of inquiry. While historians, anthropologists, and sociologists have asked questions about the culture of football, economists and experts in management and marketing have approached the sport with a very different agenda. Although these two groups of scholars undoubtedly have much to say to each other, the potential for intellectual exchange has not yet been realized. As a result, Football in the Americas would seem to hold great promise.
De Vecinos a Ciudadanos: Movimientos comunales y luchas cívicas en la historia contemporánea de Costa Rica. PATRICIA ALVARENGA VENUTOLO: Heredia, Costa Rica: EUNA, 2005.
Authors: Lehoucq Fabrice 
Published: February 2024

Patricia Alvarenga Venutolo, a historian at the National University in Heredia, Costa Rica, has written an engaging narrative about some of the highlights of communal protest in contemporary Costa Rica. By communal, she means "socially diverse groups of individuals who organize to protest concrete issues," as distinct from class-based movements (p. 1). Her main conclusion is that conflicts over the rates and quality of public services can lead to the formation of protest movements that state officials may be reluctant to deal with, but with which they ultimately do negotiate agreements.

The Wandering Signifier: Rhetoric of Jewishness in the Latin American Imaginary. ERIN GRAFF ZIVIN: Durham & London: Duke University Press, 2008
Authors: Ran Amalia 
Published: February 2024

Erin Graff Zivin's The Wandering Signifier: Rhetoric of Jewishness in the Latin American Imaginary belongs to this forming tradition that aims to explore the Judeo-Latin American field by studying late nineteenth- through late twentieth-century literature from Argentina, Brazil, Peru, Mexico, Colombia, and Nicaragua. She opts for a unique perspective by proposing that Jewishness be viewed as a wandering signifier, a floating artifact that shifts between literary texts and socio-historical contexts, a sign that may pertain to certain extra-textual circumstances, yet still remain a sublime textual representation, never fully attained.
Empire and Dissent: The United States and Latin America. FRED ROSEN (ed.): Durham, NC: Duke University Press, 2008
Authors: Weeks Gregory Weeks 
Published: February 2024

This is an ambitious but often frustrating book. Its goal, as laid out by Fred Rosen in the introduction, is to "explore the ways in which the contours of dissent and resistance have been generated by the activities of empire, as well as the ways in which the contours of empire have been given shape by opposition, resistance, and disaffection" (5). The ambition is to demonstrate the causal relationships between the empire of the United States on the one hand, and the resistance that has emerged as a result.My frustration stems primarily from the fact that the book offers no definition of "empire" despite its centrality to the chapters. Rosen does not define it in the introduction. Indeed, one has to dig deeply into Alan Knight's impressive discussion of U.S. imperialism and hegemony to find the following in endnote 24: "I have deliberately refrained from trying to define imperialism" (47; emphasis in original). Endnote 99 states very plainly that "I have made the prudent but cowardly decision to avoid attempting any definition or discussion of "resistance," a concept that, due to overuse, may be yielding diminishing returns" (52).
Cuba and the American Imagination: Metaphor and the Imperial Ethos. LOUIS A. PÉREZ Jr.: Chapel Hill: The University of North Carolina Press, 2008
Authors: Lipman Jana K. 
Published: February 2024

In Cuba and the American Imagination: Metaphor and the Imperial Ethos, Louis A. Pérez Jr. adds to his impressive oeuvre of work on US-Cuba relations in the twentieth century. With his practiced command over the archival material, Pérez examines the power of metaphor in defining the United States' imperial relationship with Cuba. Through a range of textual and visual sources, Pérez maps out the changing metaphors US actors used to depict "Cuba" from the early nineteenth century through the years following the Cuban revolution. Pérez asserts, "metaphors have consequences" (14), and he aptly argues how US representations of Cuba resulted in policies based on fictions and "figment[s] of their [US actors] own imagination" (23). Thus, this is not a book about Cuba, but rather it is a book about how North American ideas of Cuba enabled the United States to gain its "sense of self-righteous hubris," and "destiny" as it became an imperial power in the twentieth century (10).
