Abstract

Purpose

This paper aims to focus on the distributive implications of trade by studying how manufacturing workers’ relative earnings and employment have changed in post–North American Free Trade Agreement (NAFTA) Mexico (1995-2011).

Design/methodology/approach

Input–Output analysis and inequality analysis were combined to reveal the empirical relationship between trade, wage inequality and employment in the manufacturing sector in post-NAFTA Mexico.

Findings

The results reveal that the manufacturing sectors that produce for the export market tend to pay among the lowest wages and yet employ around half of the manufacturing working population; wages in labor-intensive sectors have not been increasing, while wage inequality has been rising; and employment creation due to trade is not always positive and sustained, hence does not seem to be a stable source of jobs. The paper concludes by discussing policy implications of the findings.

Originality/value

The main focus of the existing literature has been to explain the disconnection between trade and growth. This paper shifts the focus towards the distributive dimension of trade (rather than growth) by focusing on how manufacturing workers' relative earnings and employment have changed in post-NAFTA Mexico (1995-2011). Hence it attempts to contribute to the existing literature on the distributive implications of trade.

Abstract

Purpose

This paper aims to study the microstructural hot corrosion behaviour of the sintered Y2SiO5 ceramic silicate under a Na2SO4 + V2O5 mixture at an engine representative temperature of 1150°C. Y2SiO5 is a promising candidate for thermal barrier coatings (TBC) due to its excellent chemical stability at high temperatures. As a continuous source of Y3+, it is expected that Y2SiO5 environmental barrier coating may prolong the lifetime of TBC systems by stopping the degradation caused by the loss of the Y2O3 stabilizer.

Design/methodology/approach

Two routes were chosen for the yttria silicate powder synthesis by sol-gel from TEOS and APTES precursors as the difference in Si source changed the ratio of Y2SiO5/Y2Si2O7 phases. Hot corrosion studies using Na2SO4 and V2O5 mixtures were conducted on both surfaces of APTES and TEOS tablets at 1150°C for 8 h in atmospheric air. The morphology and microstructure analyses of the silicate samples after hot corrosion tests were carried out using a SEM and X-ray diffraction analyse techniques.

Findings

Based on the degradation, the general status of the APTES tablet after hot corrosion presents a better hot corrosion resistance at a temperature of 1150°C than does that of the TEOS tablet. In the TEOS tablet, the crystal morphology of NaY9Si60O26 woodchip shapes with a size of 60 µm is developed on the surface for finally initiating some cracks. In the APTES case, the crystal morphology of rod-like shapes with a size of 100 µm is developed; hence, a dense thick layer predominately postpones the reaction of V2O5 and Na2SO4 with yttria silicate, and consequently, less damage is observed.

Originality/value

Coating yttria silicate preparation is very complicated; the problems of a high synthesis temperature, long production period and low yield still need to be solved. Under these perspectives, ceramics prepared via spark plasma sintering (SPS) can reach theoretical high densities and a fine grain size can be retained after the SPS process; hence, well resistance to the corrosion in molten salts is expected to obtain for the sintered yttria silicate tablets.

Abstract

This chapter aims to reconstruct the trajectory of comparative education in Brazil using the timeline concept to identify structural elements in the emergence and reconfiguration of this field of study. The timeline historical perspective allows us to use two additional features: (a) the reconstruction of the scenario in which emerge the intellectual productions; and simultaneously (b) identify how themes, issues, and research objects appears, whether in a homogeneous association or not. These elements allow us to associate comparative and historical methods to recognize the supranational and supraregional influence, determining the configuration of what is meant by comparative education in Brazil. The text distinguishes seven different moments for the Brazilian comparative educational area, which are: (1) the study of the structure and functioning of European and North American systems education; (2) the United Nations Educational, Scientific and Cultural Organization’s (UNESCO) pioneering influence on the production of annuals; (3) the prioritization of educational practices; (4) the influence of supranational relations; (5) the focus on educational public policies; (6) new cycle of supranational influence; and (7) (re)definition of the theoretical, methodological, and epistemological anchorage of comparative education. In the last quarter century, it can be said that there is a resurgence of Comparative Education in Brazil and the region, which may be associated with strong historical influences, here reconstructed by periodization.

Abstract

Purpose

The purpose of this paper is to study insulin pump therapy and accurate monitoring of glucose levels in diabetic patients, which are current research trends in diabetology. Both problems have a wide margin for improvement and promising applications in the control of parameters and levels involved.

Design/methodology/approach

The authors have registered data for the levels of glucose in diabetic patients throughout a day with a temporal resolution of 5 minutes, the amount and time of insulin administered and time of ingestion. The estimated quantity of carbohydrates is also monitored. A mathematical model for Type 1 patients was fitted piecewise to these data and the evolution of the parameters was analyzed.

Findings

They have found that the parameters for the model change abruptly throughout a day for the same patient, but this set of parameters account with precision for the evolution of the glucose levels in the test patients. This fitting technique could be used to personalize treatments for specific patients and predict the glucose-level variations in terms of hours or even shorter periods of time. This way more effective insulin pump therapies could be developed.

Originality/value

The proposed model could allow for the development of improved schedules on insulin pump therapies.

This study analyses climate change vulnerability and adaptation in a northern province in Vietnam from the gender perspective.

Abstract

Purpose

This study analyses climate change vulnerability and adaptation in a northern province in Vietnam from the gender perspective.

Design/methodology/approach

A survey questionnaire was used to collect data for the study. The Livelihood Vulnerability Index (LVI) was calculated for 134 female and 239 male-headed households. Descriptive statistics were synthesized to investigate climate change adaptation from the gender perspective.

Findings

The results show that the LVI of female-headed households is higher than male-headed households, but the variation is negligible. In addition, female and male farmers in the study area use different methods to adapt to climate change. Female farmers have critically contributed to the family workforce and climate change adaptation. Nevertheless, female farmers have less accessibility to agricultural services such as training and credit.

Research limitations/implications

The study suggests that gendered interventions for improvement of livelihood to adapt to climate change should be developed for each aspect of the livelihood. Furthermore, enhancement of services for women and recognition of women's roles in responding to climate change would contribute to more active adaptation to climate change.

Originality/value

Studies on climate change from the gender perspective in Vietnam have been conducted on a limited scale. Particularly, there are very limited studies on climate change in association with gender issue in North Vietnam. Thus, this study will provide more insights into the gender dimension of climate change vulnerability and adaptation so that gender-based adaptation strategies can be developed.

Abstract

The Geography of Tourism in Spain is now at a par in terms of its scientific production with other European countries. Since the middle of the '80s the quality and volume of contributions is analogous to the rest of the European Union, although as a part of University Geography in Spain it has not achieved the level of dedication reached by other subjects considering the importance of tourist activities to the economy, the society and the territory of Spain. It could be said that the Geography of Tourism in Spain is in the international vanguard in dealing with Mediterranean coastal tourism, with the relationships between the residential real estate and tourism sectors and with aspects related to tourism and leisure in rural and protected areas.

Abstract

This chapter deals with the development of banking in the Crown of Aragon from the end of the thirteenth century through the establishment of money changers, which followed similar patterns as in other Western European territories. It starts with a review of existing literature and follows with an explanation on the different banking services provided by money changers and the specific legal framework that supported such activities. It then examines the geographical distribution of private banks in cities and towns within the domains of the kings of Aragon, as well as their evolution throughout the fourteenth century. After that, it offers an analysis of the most common professional profiles among these bankers and financers. Finally, drawing on a heterogeneous pool of unpublished data, it seeks to shed light on the diversity of investors and clients of these establishments, a crucial proof of their role in integrated financial markets.

Abstract

Purpose

This paper aims to broadly address a PhD research stream that the author has been conducting to date, whose historical objective is press photography, specifically the published images in La Jornada newspaper. A visual speech of the various contexts lived in Mexico at the end of the twentieth century. In the following lines, the author will present her methodology proposal with the aim of learning and analyzing the speech created by press photography and its relation to historical reality. A journalistic speech generating a language describing events, but at the same time a language manipulated by the subjectivity of the author – the press photographer. A historical timeline of which the photojournalist was part and which influenced the manner historical reality was perceived by the receiving social group.

Design/methodology/approach

It is important to clarify that this database does not intend to replace the estimations which could be obtained by directly and individually analyzing each photograph. However, this instrument has allowed the author to collect a great quantity of readable graphic and textual information, as well as to describe the characteristic attributes of each image as a documentary unit. In other words, the author intends to address the visual events as a part of the historical events, as claimed by the Mexican historian Ricardo Pérez Montfort. This to provide an in-depth study on how historical, social, cultural and political phenomena were registered by press photography; not omitting history, this specific moment, punctually requires photography and written journalism as a vestige. The latter not only with the purpose of going further on the functions of photography but also on the significance of the photographic phenomenon and the visual speech within social and cultural history of a country.

Findings

Furthermore, the author will present, to the extent possible, some elements which have allowed the identification of the manner in which the editor(s) of the newspaper impacted the presentation of visual speech, as well as the interests and visions of the social group they represent. This is a way to go further on different assumptions, such as the person taking the picture, the person editing it – after reaching the editorial and ideological line of the newspaper – as well as the person publishing the picture; a new manner to address editorial work and photojournalism on written media. To achieve the aforementioned aim, this essay comprehends the intertextuality and visual production, as well as the contexts lived throughout the six-year Presidential terms of office of Miguel de la Madrid Hurtado, Carlos Salinas de Gortari and Ernesto Zedillo Ponce de León, through diverse published images in La Jornada newspaper from 1984 to 2000.

Originality/value

This research not only addresses the generated material by the photojournalists of La Jornada newspaper during this period but also includes, as a part of the oral history methodology, the testimonies of some assistant directors, people in charge of the photography department, the editor, the designer and photographers who stood out in the newspaper. In addition, the author has a database which has allowed to collect, store and connect information present in each of the photographs published on different covers and back covers of the newspaper. It comprises 15 categories which have been nurturing the database (reviewed dates, journalistic and photographic genders, reporters, pages, published photographs, photograph format, themes of the photographs, places, characters, titles of the photographs, photograph caption, credit, photograph composition, angle and time). It is important to clarify that this database does not intend to replace the estimations which could be obtained from directly and individually analyzing each photograph. However, this instrument has allowed the author to collect a great quantity of readable graphic and textual information, as well as to describe the characteristic attributes of each image as a documentary unit.

Abstract

This chapter aims to contribute to the study of social protests around the world and particularly in Latin America during the 1960s and 1970s, with a focus on an Argentinean case. Throughout these years, Argentina like many other Latin American societies witnessed the growth and development of intense social and political struggles in concert with the armed insurgency. Did workers or other popular social sectors support guerrilla organizations in Argentina? What was the interconnection between working-class and armed insurgent struggle? This chapter examines these liaisons by studying the case of an industrial city that has been identified to be a paradigm of labor radicalization and political violence in Argentina—Villa Constitución. Through the reanalysis of documents and sources as well as interviews, we discuss established interpretations on armed and labor struggles that reveal a broader heterogeneity in the forms of social support to revolutionary violence. Solidarity among workers and armed militants appears in (1) the actions of militant workers at their workplaces, and (2) the armed actions organized by militants in support of worker’s fights.” These two groups reinforced each other's activism. But, by no means can we directly deduct from this that rank and file workers immediately identified their strikes with ideologically revolutionary objectives.

Abstract

Purpose

Studies of Spanish literature during the late nineteenth century and the first one-third of the twentieth century are evolving from research on canonical writers to the study of “odd and forgotten” authors, themes and genres during what is now called the Other Silver Age. This paper aims to focus on the work undertaken in the field of literary translation by the women writers of this period.

Design/methodology/approach

Mnemosyne is an open-access digital library that allows data modeling for specific collections (women translators, science fiction, etc.) in support of research and teaching on Silver Age Spain. The first version of the library is stored on the server at the Universidad Complutense Library, and it is linked to the collections of the digital library HathiTrust and Biblioteca Nacional de España. Behind the scenes of Mnemosyne’s public presence online, the project is developing with the aid of the tool Clavy which is a rich internet application that is able to import, preserve and edit information from big data collections of digital objects so as to build bridges between institutional and digital repositories and create collections of enriched digital content. See:http://repositorios.fdi.ucm.es/mnemosine/queesmnemosine.php

Findings

The Collection Women Translators in Spain (1868-1936) inside Mnemosyne selects, categorizes and makes visible in digital format women translators and literary translations that belong to a forgotten repertoire to allow the historical review of the period. The digital collection of Spanish Women Translators pretends to be a field of international experimentation for the creation of interoperable semantic networks through which a large group of scholars could generate innovative research and theoretical reading models for literary texts. See:http://repositorios.fdi.ucm.es/mnemosine/colecciones.php

Research limitations/implications

Clavy also provides a basic system of data visualization, edition and navigation. There are plans to integrate @Note, a collaborative annotation application, into Clavy. These two computational tools were developed by the software languages research group ILSA[1] at the Universidad Complutense de Madrid.

Practical implications

Its been followed NEWW Women Writers’ categories concerning biographical categories as successful standard for ensuring interoperability in the near future: children, marital status, social class, religion, profession and other activities, financial aspects, memberships. See:http://repositorios.fdi.ucm.es/mnemosine/ver_documento.php?documento=208369

Social implications

These women also showed their interest in the writings of contemporary women by translating their works into Spanish or glossing foreign ideas about how the modern woman should be, think or behave. This digital collection shows the first steps of the intellectual women in the South of Europe.

Originality/value

To incorporate specially tailored metadata for the women translators’ collection into Mnemosyne, it will be necessary to use of Clavy’s extensibility to account for the particularities of the women translators’ collection. This is where prior knowledge of this literature’s historical and cultural context proves indispensable. In particular, the specific metadata model for the women translators’ collection incorporates elements that reflect the literary, historical and cultural characteristics of the collections.
