Full textAbstract:
Literature on international migration, assimilation, and transnationalism continues to be concerned with questions about ties that migrants and their descendents have with their homelands, coethnics, and the native-born population. Tomás R. Jiménez's Replenished Ethnicity: Mexican Americans, Immigration, and Identity and Joanna Dreby's Divided by Borders: Mexican Migrants and their Children provide important perspectives on different aspects of the larger phenomenon of international migration from Mexico to the United States that is a consequence of labor demand in the United States, economic need and job scarcity in Mexico, and a global economy. Both books deal with social life that takes place across ethnic boundaries, within ethnic groups, and across national borders. Taking qualitative approaches and dealing with the perennial tension between inclusion and exclusion, these books analyze the experiences and perspectives of Mexican migrants, Mexican children, and Mexican Americans.

Full textAbstract:
This article follows Mexican Chinese families from Mexico, across the Mexican-U.S. border, to China, and back to Mexico. Settling in northern Mexico in the nineteenth century, Chinese formed multiple ties with Mexicans. An anti-Chinese movement emerged during the Mexican Revolution and peaked during the Great Depression. The Mexican government deported several thousand Chinese men and their Mexican-origin families from Sonora and neighboring Sinaloa, some directly to China and others to the United States, whose immigration agents also deported the families to China. They arrived in Guangdong (Canton) Province but eventually congregated in Macau where they forged a coherent Mexican Chinese enclave. Developing a strategic Mexican nationalism, they appealed for repatriation. The Mexican Chinese "became Mexican" only after authorities compelled them to struggle for years from abroad for the inclusion of their mixed-race families in the nation. They became diasporic citizens and fashioned hybrid identities to survive in Mexico and China.

Full textAbstract:
AbstractThis article traces the significant yet largely unexplored experience of transnationalism in the lived religious experiences of Mexican and Mexican American Catholics by focusing on the parish as a central unit of analysis. Within this analysis, the parish unit is rethought as an analytical unit in two important regards. First, the way in which parish life in rural Mexico has been predominately conceptualized as one whose rhythm revolves around a traditional ritual calendar centered on community celebrations of particular religious holidays and localized votive devotions needs to be replaced. Based on research from an ongoing historical case study (1890-present) of a central Mexican parish, Nuestra Señora del Rosario in Coeneo, Michoacán, and on other parishes, the rhythm of parish life has clearly shifted to celebrations of marriages and baptisms. These religious celebrations of marriages and baptisms in Mexico have become the focal point of identity and community in this transnational Mexican and Mexican American experience. These sacraments of baptism and marriage have multiple meanings that not only include universal Catholic doctrines but also notions of family, community, and a particular appreciation for the sacralized landscape of their Mexican parish. Second, notions of parish boundaries as fixed and parish affiliation as singular must be reconsidered because many Mexicans and Mexican Americans living in the United States consider themselves to be active members in at least two parishes: one in Mexico and one or more in the United States.

Full textAbstract:
In 2016, research suggested there might be up to 36 transboundary aquifers located along the border between Mexico and the U.S. The main contribution of this study was to put together the available segments already existent in the literature without considering the validity of the criteria used to define the boundaries of those segments. In 2018, updated research reported 33 hydrogeological units (HGUs) crossing the boundaries between Mexico and Texas. This later analysis included the homogenization of geological nomenclatures, standardization of geological and hydrogeological criteria, using a specific methodology to correlate, identify, and delineate each HGU. The purpose of this paper is to use this latter methodology and expand the same analysis to include the transboundary aquifers between Baja California/California, Sonora/Arizona, and Chihuahua/New Mexico. Results of this study indicate that a total of 39 HGUs have been identified in this region which accounts for an approximate shareable land of 135,000 km2 where both countries share half of the area. From the total shareable area, around 40% reports good to moderate aquifer potential and water quality, of which 65% is in the U.S. and 35% on the Mexico side. Border-wide, the total number of HGUs in the border region between Mexico and the United States is 72, covering an approximate area of 315,000 km2 (180,000 km2 on the U.S. side and 135,000 km2 on the Mexico side). The total area that reports good to moderate aquifer potential as well as good to regular water quality ranges between 50 and 55% (of which approximately 60% is in the U.S. and the rest in Mexico).

Full textAbstract:
AbstractThis article examines relations between the Mexican state and transmigrants through an analysis of migrant- and state-led transnational practices and policies. It addresses discussions of the strength and extent of Mexican state control and hegemony as well as debates in the transnationalism literature on the potential autonomy of transmigrant groups and the role of subnational linkages. The analysis is based on information on transmigrant organizations and Mexican political authorities in Los Angeles and Mexico and focuses on Zacatecas. Mexican transmigrant organizations predate current state initiatives aimed at Mexicans in the United States, but state involvement has been crucial to the institutionalizing of transnational social spaces. The state's hegemonic project involves the largely symbolic reincorporation of paisanos living abroad back into to the nation but depends on provincial and municipal authorities and transmigrant organizations for implementation. Because these vary, the project has been implemented unevenly. The complexity of these processes can be captured only by examining transnational social spaces at a subnational level. The case of Zacatecas shows how a corporatist and semi-clientelist transmigrant organization has managed to gain concessions that broaden opportunities for participation. It remains to be seen whether and how promises of political representation will be fulfilled.

Full textAbstract:
One of the most important aspects of the recent mass migrations of Latin Americans into previously remote regions of the hemisphere is the impact these have had on areas cut by international boundaries. With the exception of the United States-Mexico border, however, historical examination of the process is still in its infancy. And few observers have developed a satisfactory theoretical basis explaining an admittedly complex process.One exception was Cuban historian Jorge Mañach, who spoke of “balanced” and “unbalanced” frontiers, largely in the context of the United States-Mexican boundary. He believed that power distribution between nations determined the degree to which their frontier interrelationships were equal or unequal. In Mañach's view, when a politically or economically weaker nation shares a boundary with one that is stronger, overall communication is sacrificed and the stronger power inevitably “spills over” into the neighboring region, economically and culturally.

Full textAbstract:
In the Madrean Sky Islands of western North America, a mixture of public and private land ownership and tenure creates a complex situation for collaborative efforts in conservation. In this case study, we describe the current ownership and management structures in the US-Mexico borderlands where social, political, and economic conditions create extreme pressures on the environment and challenges for conservation. On the United States side of the border, sky island mountain ranges are almost entirely publicly owned and managed by federal, state, and tribal organizations that manage and monitor species, habitats, and disturbances including fire. In contrast, public lands are scarce in the adjacent mountain ranges of Mexico, rather, a unique system of private parcels and communal lands makes up most of Mexico’s Natural Protected Areas. Several of the Protected Area reserves in Mexico form a matrix that serves to connect scattered habitats for jaguars dispersing northward toward public and private reserves in the United States from their northernmost breeding areas in Mexico. Despite the administrative or jurisdictional boundaries superimposed upon the landscape, we identify two unifying management themes that encourage collaborative management of transboundary landscape processes and habitat connectivity: jaguar conservation and wildfire management. This case study promotes understanding of conservation challenges as they are perceived and managed in a diversity of settings across the US-Mexico borderlands. Ultimately, recognizing the unique and important contributions of people living and working under different systems of land ownership and tenure will open doors for partnerships in achieving common goals.

Full textAbstract:
The tribe Stenochiini Kirby, 1837 comprises six genera in North America with most species occurring in the tropical and temperateregions of the continent. Only two species in the genus Strongylium Kirby, 1818 have previously been reported from west of theContinental Divide in the United States from Arizona and New Mexico and no members of the tribe have been reported from the stateof Sonora, Mexico. We here report Strongylium tenuicolle (Say, 1826), known to be widely distributed east of the Rocky Mountains,from west of the Continental Divide for the first time from both Arizona and New Mexico. We similarly report the first records ofboth Strongylium apache Triplehorn and Spilman, 1973 and Strongylium atrum Champion, 1888 from Sonora. Oploptera chamelensis(Doyen, 1990) was previously known only from the type series from Jalisco, Mexico and is here reported from Sonora, which thereby extends the known range of this genus significantly. To promote consistency in generic recognition, we propose the transfer of Oploptera simplicicollis (LeConte, 1878) New Combination from Strongylium for the species distributed across the southeastern United States. Species diagnoses are given, and generic boundaries are discussed along with the expected diversity of the Sonoran Desert region.

Full textAbstract:
This essay examines the history of the taco in Mexico and the United States as a way of shifting the focus of "McDonaldization" from technology to ethnicity. It begins with the origins of the taco in Mexico to show that it was a product of modernity rather than an ancient tradition transformed by Yankee ingenuity. It then examines patent records, cookbooks, and archival sources to demonstrate that all aspects of the Mexican American taco, including the pre-fried taco shell, were actually invented within the ethnic community. Indeed, new forms of tacos were one of the many ways in which ethnic women mediated the boundaries between Mexican family traditions and U.S. cultural citizenship. These sources also refute corporate hagiography attributing the fast food taco to Glen Bell, founder of Taco Bell. Finally, using GIS to map taco shops against tract-level census data, the essay concludes that non-ethnic fast food chains succeeded by marketing tacos as a form of exoticism or safe danger within the segregated landscape of 1950s Los Angeles.

Full textAbstract:
Recent strategies to enforce the United States boundary with Mexico have shifted undocumented immigrants into remote lands federally designated as protected areas (as in national park or national wildlife refuge). Government and media institutions represent such entries as a threat to nature. In this paper we argue that representations and interpretations of threats to nature in border-protected areas are laden with identity attachments. In repeatedly defining that which is threatened as ‘American’, such discourses work to draw boundaries around the nation, thereby narrating inclusion and exclusion.

Full textAbstract:
The Mexican transition zone (MTZ) is the complex area where the Neotropical and Nearctic biotas overlap, including south-western United States, Mexico and a large part of Central America extending to the Nicaraguan lowlands. In a strict sense, it corresponds to the mountain highlands of Mexico, Guatemala, Honduras, El Salvador and Nicaragua. We review Halffter's theory explaining the biotic evolution of the MTZ, including the description and discussion of the distributional patterns and cenocrons recognized within it. Distributional patterns are generalizations that help analyse and compare distributions of different taxa. Cenocrons correspond to sets of taxa that share the same biogeographic history, constituting identifiable subsets within the transitional biota by their common biotic origin and evolutionary history. The heuristic value of distributional patterns and cenocrons lies in their application to formulate hypotheses on biotic assembly in the geographical-ecological space, to analyse the ecological response to anthropic impact, to analyse altitudinal patterns and to undertake time-slicing in cladistic biogeography. Three case studies are analysed with some detail: the Neotropical genus Canthon and the tribe Phanaeini and the Holarctic/Nearctic subfamily Geotrupinae. The Paleoamerican and Mexican Plateau cenocrons define the approximate boundaries of the MTZ, whereas the Mountain Mesoamerican, Nearctic and Typical Neotropical cenocrons correspond to the more conventional boundaries of the Nearctic and Neotropical regions. The biotic assembly of the MTZ is summarized into five stages: in the Jurassic-Cretaceous, the Paleoamerican cenocron (later diversified into five varieties) extended in Mexico; in the Late Cretaceous-Palaeocene, the Mexican Plateau cenocron dispersed from South America; in the Oligocene-Miocene, the Mountain Mesoamerican cenocron dispersed from the Central American Nucleus; in the Miocene-Pliocene, the Nearctic cenocron dispersed from northern North America; and in the Pleistocene, the Typical Neotropical cenocron dispersed from South America. Finally, we review the impact of Halffter's MTZ, with particular reference to dispersal, track, cladistic biogeographic, endemicity and phylogeographic analyses, as well as biogeographic regionalization.

<p><em>Prior research reports mixed results regarding the economic impacts of crime. This study employs data from all regions of Mexico, including border regions in both the north and the south, to examine the effects of homicides on retail activity across Mexico during a period of escalating violence. The results indicate that one additional homicide within a municipality eliminates one retail establishment and one paid job in the retail sector. Furthermore, the negative consequences of violent crime for retailers are augmented by proximity to an international border. This is consistent with previous research findings that cross-border shopping is a key feature of commerce along the international boundaries of Mexico. It suggests that crime waves may disproportionately impact border city retail activity by partially diverting customer traffic to stores located in neighboring countries. This result is also consistent with the finding of recent research that violent conflict in northern Mexico resulted in increased retail activity in some United States border cities.</em></p>

Full textAbstract:
Although the establishment of species boundaries in the genus Daphnia is complicated by the prevalence of interspecific hybrids and by phenotypic plasticity, genetic studies can resolve these complexities. This investigation employed allozyme analyses to critically assess species boundaries in members of the Daphnia pulex group from the south-central United States and Mexico. These studies demonstrated the occurrence of three common Nearctic species (obtusa, pulex, pulicaria), but also revealed the occurrence of three previously unrecognized taxa (cheraphila, pileata, prolata). All of these newly described species have their distributional centroid in this region of North America and are restricted to clay-water habitats. F1 hybrids were detected between three pairs of species (cheraphila × prolata, obtusa × pileata, pulex × pulicaria), but only the latter hybrids were common. The discovery of daphniid taxa endemic to this region of North America contrasts with the results of a broader survey of sites in Canada, and suggests that additional species await description from other unglaciated regions of North America.

Educational institutions developed in Tucson, Arizona in the last quarter of the nineteenth century, during a critical time in cultural and political shifts of power between Anglo and Mexican elites in Southwestern United States. My qualitative analysis reconstructs language policies in the incipient educational system in Territorial Tucson. This article examines official and unofficial language policies in both public and private schools in Tucson that reflected this accommodation of power and the negotiation of a new racial hierarchy in the context of westward expansion. I argue that the private schools Mexican elites founded in this period maintained bilingual instruction and promoted biliteracy as a means of racially and linguistically distancing themselves from Anglos, Indians and Mexicans from lower socioeconomic classes in public schools.

Full textAbstract:
During the years 2008-2012, the El Paso, Texas-Ciudad Juárez, Chihuahua border region between the United States and Mexico saw a wave of violence that occurred as a result of the so-called “drug war” between the Juárez and Sinaloa drug cartels. As the criminal organizations began recruiting local gangs for their enforcement strategies, the violence soon spiraled beyond the context of the drug trafficking industry, generating mayhem and social decay throughout Ciudad Juárez. In four years, the death toll in the city amounted to 10,882, with 3,622 bodies in 2010. This article discusses the impact of the violence in the region as experienced by border residents and in relation to policy responses by the U.S. and Mexican governments. Drawing on fieldwork and interviews conducted in January-May 2010 with members of the border community, it focuses on the interviewees’ experiences in 2010. The discussion of violence is contextualized as a global crisis, with ramifications upon urgent issues of citizenship and political and human rights across national boundaries.

Full textAbstract:
Spurred by burgeoning racist and xenophobic immigration policy and rhetoric, we analyzed the writing of seven second-grade children about their experiences of living connections that span the United States–Mexico border. Informed by research on children’s testimonios in literacy classrooms and Anzaldúa’s concept of the border/lands, we drew on feminist and critical poststructuralist theories to examine how children’s writing rhetorically and aesthetically engaged with the affective, political, and ideological dimensions of borders and the rhetorical and material violence of hostile policies. Methodologically, we conducted close readings of children’s writing, tracing how they disrupted boundaries, including those constructed both physically and ideologically across nations and between concepts, identities, and feelings. This analysis underscores children’s keen insights into their political and personal worlds, the importance of writing pedagogies that invite children to engage with the personal and political, and the need for methods of analysis that attend to the poetics of children’s perspectives.

The aim of this essay is to illuminate the lived experiences of Victoria—an undocumented immigrant woman of Mexican origin working and living in the United States. Drawing on an in-depth interview conducted with Victoria following the election of Donald Trump as president of the United States, we identify a set of discursive and material conditions that inform her lived reality. By examining three mutually constituting stages of Victoria’s life, we invite readers to consider how the imbricated nexus between global manifestations of colonization, migration, and the political rise of right-wing extremism is embodied and negotiated locally by one particular woman. To aid in theoretically informing the excerpts provided by Victoria, we draw on Judith Butler’s recent works in which she develops, individually and collaboratively, ideas of dispossession and precariousness. We find that dispossession and precariousness foreground the currents of vulnerability that are located palpably in Victoria’s narrative. Finally, by engaging with a genre of feminine writing that collapses the traditional boundaries between theory and practice, we revisit the question of praxis in relation to the researchers’ responsibility toward the participants of their study.

Full textAbstract:
Donald J. Pinkava is best known for his application of cytogenetics in unraveling the complex interspecific hybridization in the prickly pear genus Opuntia Mill. in the southwestern United States extending down into northern and central Mexico. Using cytogenetics, Pinkava delimited species boundaries within Opuntia for taxonomic treatments. His work on Opuntia in the Chihuahuan Desert led to later comprehensive contributions in the Flora of North America and the Flora of Arizona that include opuntias not only in the Southwest but in every US state. Pinkava's systematic knowledge, as reflected in his taxonomic treatments provided the basic scientific framework needed for ongoing conservation of Cactaceae in the Southwest to the present day. Interestingly, the starting point for all of Pinkava's contributions in Cactaceae began with his initial studies of Asteraceae as a student of T. Richard Fisher at The Ohio State University (OSU), an institution with longstanding research interests in the Asteraceae. It is there that he selected a genus, Berlandiera DC as his dissertation topic. Ironically, this genus has a range from the drier sites of the Eastern Coastal Plains, into the Ozark and Ouachita Mountains, with a disjunct distribution in the mountain floras of southeastern Arizona and Northern Mexico. Like Berlandiera, Pinkava’s own work reflects techniques and training in the eastern US, that migrated and was used as the basis for his groundbreaking studies of Cactaceae in the Southwest.

Full textAbstract:
We have explored the technical utility of analyzing massive sets of digital 2D seismic data, collected and processed in dozens of different surveys, conducted more than 25 years ago, using batch, automated and unsupervised pattern recognition techniques to produce a basin-wide map of the top of salt. This workflow was developed for the United States portion of the Gulf of Mexico to detect top-salt boundaries on 2D poststack migrated lines. Texture-based attributes as well as novel, reflector-based attributes were used to discriminate between salt and nonsalt on each seismic line. Explicit measures of accuracy were not calculated because the data are unlabeled, but an assessment of confidence was used to score the boundaries. The depth to the top of the salt was estimated for more than 67% of the study area ([Formula: see text] or [Formula: see text]), 17% of the study area had insufficient data for processing and analysis, and 16% of the area did not meet confidence requirements for inclusion. The final results compared well with published maps of salt and the locations of salt-trapped fields. Reliable mapping of salt deeper than 6 s two-way time could not be achieved with this data set and approach because many seismic images had indistinguishable features at this depth. The computing time was greater than linear in the number of lines, but parallelization and changes in hardware configuration could reduce the run time of about three weeks to about three days.

Full textAbstract:
The New World Jerusalem crickets currently consist of 4 genera: Stenopelmatus Burmeister, 1838, with 33 named entities; Ammopelmatus Tinkham, 1965, with 2 described species; Viscainopelmatus Tinkham, 1970, with 1 described species, and Stenopelmatopterus Gorochov, 1988, with 3 described species. We redefine the generic boundaries of these 4 genera, synonymize Stenopelmatopterus under Stenopelmatus, and synonymize Viscainopelmatus under Ammopelmatus. We then discuss, and illustrate, all the types of the species of Stenopelmatus, all of which only occur south of the United States’ border. We recognize as valid the following 5 described Mexican and Central American species: S. ater, S. piceiventris, S. sartorianus, S. talpa, and S. typhlops. We declare the following 13 described Mexican and Central American Stenopelmatus taxa as nomen dubium: S. calcaratus, S. erythromelus, S. guatemalae, S. histrio, S. lessonae, S. lycosoides, S. mexicanus, S. minor, S. nieti, S. sallei, S. sumichrasti, S. toltecus, and S. vicinus. We designate a neotype for S. talpa and lectotypes for S. ater, S. guatemalae, S. histrio, S. lessonae, S. mexicanus, S. minor, S. nieti, S. sallei, S. sumichrasti, and S. toltecus. We assign a type locality for S. piceiventris. We concur with the previous synonymy of S. politus under S. sartorianus. We describe 14 new species of Stenopelmatus from Mexico, Honduras and Ecuador, based on a combination of adult morphology, DNA, calling song drumming pattern, distribution, and karyotype: S. chiapas sp. nov., S. cusuco sp. nov., S. diezmilpies sp. nov., S. durango sp. nov., S. ecuadorensis sp. nov., S. faulkneri sp. nov., S. honduras sp. nov., S. hondurasito sp. nov., S. mineraldelmonte sp. nov., S. nuevoleon sp. nov., S. perote sp. nov., S. saltillo sp. nov., S. sanfelipe sp. nov., and S. zimapan sp. nov. We transfer the following 16 described United States taxa, plus S. cephalotes from the “west coast of North America”, from Stenopelmatus to Ammopelmatus: A. cahuilaensis, A. californicus, A. cephalotes, A. fasciatus, A. fuscus, A. hydrocephalus, A. intermedius, A. irregularis, A. longispinus, A. mescaleroensis, A. monahansensis, A. navajo, A. nigrocapitatus, A. oculatus, A. pictus, and A. terrenus, along with the Mexican taxon A. comanchus: these species will be discussed in a subsequent paper (Weissman et al. in prep). We believe that all new Jerusalem cricket species descriptions should include, at a minimum, calling drum (most important) and DNA information.

When the American Studies Association chose “Boundaries of American Culture” as the theme and San Diego as the site of its 1985 biennial convention, it made a particularly appropriate match between theme and site. Seen from my hotel balcony in a hazy autumnal glow, San Diego appeared a boundary city in at least three senses of relevance to the Association's work. First, lying at the border of the United States and Mexico, it hinted at the rich possibilities available to an American Studies willing to reach imaginatively beyond national boundaries, both north and south, toward a genuinely pan-American studies. Second, as a three-block walk to the beach from the convention hotel amply confirmed, San Diego borders what several commentators have called “the Mediterranean of the future”–a major arena of the globe too long and too much neglected by most Americans and Americanists. It was stimulating to welcome to the convention distinguished visitors from a dozen Asian and South Pacific countries, and more than a few speakers expressed the hope that such interaction would significantly further the comparativist and internationalist perspectives that they believed increasingly incumbent upon a nonparochial American Studies. Certainly the heartening presence in San Diego of both long-time and new colleagues from Europe, Canada, Latin America, Asia, and the South Pacific reflected a slowly but steadily growing impulse in the Association, a concrete dramatization of the premise that ideas and values, not to mention trade and power, do not stop at a nation's borders, although they may be often slowed down or even transformed at those borders.

Full textAbstract:
Chicana history has come a long way since its inception in the 1960s and 1970s. While initially a neglected area of study limited to issues of labor and class, today scholars in history, literature, anthropology, and sociology, among others, study topics of gender, culture, and sexuality, as well as youth culture, reproductive rights, migration, and immigration. In the process, these scholars contribute to the collective project of Mexican and Mexican American women’s history in the United States, making it diverse in its analytical themes, methodologies, and sources. Indeed, Chicana history is not confined by disciplinary boundaries. Rather, its cross-disciplinary nature gives it life. This article charts that interdisciplinarity and demonstrates its significance in expanding and recasting Chicano history more broadly.

Full textAbstract:
Between 1850 and 1930, demographic upheaval in the United States was connected to reorganization of the racial order. Socially and politically recognized boundaries between groups shifted, new groups emerged, others disappeared, and notions of who belonged in which category changed. All recognized racial groups—blacks, whites, Indians, Asians, Mexicans and others—were affected. This article investigates how and why census racial classification policies changed during this period, only to stabilize abruptly before World War II. In the context of demographic transformations and their political consequences, we find that census policy in any given year was driven by a combination of scientific, political, and ideological motivations.Based on this analysis, we rethink existing theoretical approaches to censuses and racial classification, arguing that a nation's census is deeply implicated in and helps to construct its social and political order. Censuses provide the concepts, taxonomy, and substantive information by which a nation understands its component parts as well as the contours of the whole; censuses both create the image and provide the mirror of that image for a nation's self-reflection. We conclude by outlining the meaning of this period in American history for current and future debates over race and classification.

Full textAbstract:
PurposeThis paper seeks to examine the export competitiveness and concentration level of the 15 top sugar exporting countries over the last 18 years (2001–2018) with special reference to India.Design/methodology/approachFirst, the paper utilizes a review based approach and explains the structures of major sugar economies in context to protected and unprotected perspectives. Subsequently, empirical research was carried out to assess the competitiveness level of sugar using Revealed Comparative Advantage (RCA) approach and Hirschman Herfindahl Index.FindingsThe study found structural changes in cane or beet sugar, and molasses over the time period between 2006 and 2015. Further, the findings confirmed that despite the stringent regulations in European Union, the United States of America, Guatemala, Mexico, Thailand, China, and India, the comparative advantage is high up to seven to nine sugar categories. Besides, despite the indulgent regulations in the Colombia, Brazil, and Canada, the comparative advantage is only consistent up to two to three sugar categories.Research limitations/implicationsThis study provides an overview of competitiveness patterns of 15 sugar exporting countries and further compare their comparative and concentration levels. In this context, in future, it would be interesting to study the macro-economic and firm and industry-specific factors which may strengthen the study findings.Practical implicationsThis study suggests that the sugar export of few countries (i.e. Mexico and Canada) is restricted up to their trade pacts and free trade zones which is restricting the competitiveness level and performance. Accordingly, such countries need to enlarge their business boundaries to foster their export competitiveness level. Rational subsidies and governmental assistance in diversification schemes in terms of products' range and sustainable processes can make India a consistent exporter in more categories.Originality/valueAlthough, the previous studies attempted to examine the sugar industry with particular country context, this study enlarge the body of knowledge through simultaneously examining the sugar export scenario of fifteen sugar exporting countries and providing a broad comparative view of their competitiveness and concentration levels.

"Assessing the Value of Soil Inorganic Carbon for Ecosystem Services in the Contiguous United States Based on Liming Replacement Costs." Land 7, no. 4 (November 30, 2018): 149. http://dx.doi.org/10.3390/land7040149.
Full textAbstract:
Soil databases are very important for assessing ecosystem services at different administrative levels (e.g., state, region etc.). Soil databases provide information about numerous soil properties, including soil inorganic carbon (SIC), which is a naturally occurring liming material that regulates soil pH and performs other key functions related to all four recognized ecosystem services (e.g., provisioning, regulating, cultural and supporting services). However, the ecosystem services value, or “true value,” of SIC is not recognized in the current land market. In this case, a negative externality arises because SIC with a positive value has zero market price, resulting in the market failure and the inefficient use of land. One potential method to assess the value of SIC is by determining its replacement cost based on the price of commercial limestone that would be required to amend soil. The objective of this study is to assess SIC replacement cost value in the contiguous United States (U.S.) by depth (0–20, 20–100, 100–200 cm) and considering different spatial aggregation levels (i.e., state, region, land resource region (LRR) using the State Soil Geographic (STATSGO) soil database. A replacement cost value of SIC was determined based on an average price of limestone in 2014 ($10.42 per U.S. ton). Within the contiguous U.S., the total replacement cost value of SIC in the upper two meters of soil is between $2.16T (i.e., 2.16 trillion U.S. dollars, where T = trillion = 1012) and $8.97T. States with the highest midpoint total value of SIC were: (1) Texas ($1.84T), (2) New Mexico ($355B, that is, 355 billion U.S. dollars, where B = billion = 109) and (3) Montana ($325B). When normalized by area, the states with the highest midpoint SIC values were: (1) Texas ($2.78 m−2), (2) Utah ($1.72 m−2) and (3) Minnesota ($1.35 m−2). The highest ranked regions for total SIC value were: (1) South Central ($1.95T), (2) West ($1.23T) and (3) Northern Plains ($1.01T), while the highest ranked regions based on area-normalized SIC value were: (1) South Central ($1.80 m−2), (2) Midwest ($0.82 m−2) and (3) West ($0.63 m−2). For land resource regions (LRR), the rankings were: (1) Western Range and Irrigated Region ($1.10T), (2) Central Great Plains Winter Wheat and Range Region ($926B) and (3) Central Feed Grains and Livestock Region ($635B) based on total SIC value, while the LRR rankings based on area-normalized SIC value were: (1) Southwest Plateaus and Plains Range and Cotton Region ($3.33 m−2), (2) Southwestern Prairies Cotton and Forage Region ($2.83 m−2) and (3) Central Great Plains Winter Wheat and Range Region ($1.59 m−2). Most of the SIC is located within the 100–200 cm depth interval with a midpoint replacement cost value of $2.49T and an area-normalized value of $0.34 m−2. Results from this study provide a link between science-based estimates (e.g., soil order) of SIC replacement costs within the administrative boundaries (e.g., state, region etc.).

Full textAbstract:
The Colorado Plateau occupies much of the southwestern United States including portions of Arizona, Colorado, Utah, and New Mexico. This region presents unobstructed views from mesa tops, beautifully colored soils, lone standing buttes, and canyons cut thousands of feet deep. The Colorado Plateau represents a well-preserved window into the Earth’s history. Today, the rocks of the Colorado Plateau lie roughly horizontally, as they were deposited hundreds of millions of years ago. The Plateau’s rise has motivated rivers, in their downhill progress, to carve innumerable canyons. These river canyons allow any nature-lover the opportunity to gaze at 100s of millions of years of geologic history. Within the larger Colorado Plateau, the Paria Plateau straddles the Utah and Arizona borders, and includes the Vermilion Cliff s National Monument, the Paria Canyon-Vermilion Cliffs Wilderness Area, and the southern extent of the Grand Staircase Escalante National Monument (GSENM; pre-2018 boundaries). The Paria Plateau is best known for spectacularly colored, wind-sculpted features such as Coyote Buttes and “The Wave,” where vivid colors accent cross-strata resembling a cresting ocean wave. The Plateau is also recognized for the geologically notable Vermilion Cliff s, Buckskin Gulch slot canyon, White Pocket area, and the Paria River Canyon. Although only two, dual-lane highways circumvent the plateau, several wash-boarded gravel and deeply mud-rutted roads allow access to its interior. From these dirt roads, a few sandy, four-wheel drive paths diminish as they extend and branch into the plateau’s interior. Overall, the Paria Plateau is a relatively quiet and little-visited wilderness.

Full textAbstract:
A multiscale analysis is conducted in order to examine the physical processes that resulted in prolonged heavy rainfall and devastating flash flooding across western and central Tennessee and Kentucky on 1–2 May 2010, during which Nashville, Tennessee, received 344.7 mm of rainfall and incurred 11 flood-related fatalities. On the synoptic scale, heavy rainfall was supported by a persistent corridor of strong water vapor transport rooted in the tropics that was manifested as an atmospheric river (AR). This AR developed as water vapor was extracted from the eastern tropical Pacific and the Caribbean Sea and transported into the central Mississippi Valley by a strong southerly low-level jet (LLJ) positioned between a stationary lee trough along the eastern Mexico coast and a broad, stationary subtropical ridge positioned over the southeastern United States and the subtropical Atlantic. The AR, associated with substantial water vapor content and moderate convective available potential energy, supported the successive development of two quasi-stationary mesoscale convective systems (MCSs) on 1 and 2 May, respectively. These MCSs were both linearly organized and exhibited back-building and echo-training, processes that afforded the repeated movement of convective cells over the same area of western and central Tennessee and Kentucky, resulting in a narrow band of rainfall totals of 200–400 mm. Mesoscale analyses reveal that the MCSs developed on the warm side of a slow-moving cold front and that the interaction between the southerly LLJ and convectively generated outflow boundaries was fundamental for generating convection.

Full textAbstract:
Abstract The Incorporated Research Institutions for Seismology Earthquake Browser (IEB; see Data and Resources) is a web-based tool that enables anyone to query an earthquake database composed of over five million events recorded over the past 50 yr. The IEB visitor can query on earthquake magnitude, depth, timing, and location and can visually display the results in 2D map view or as an interactive pseudo 3D view. The user can toggle features such as plate tectonic boundaries, terrain or satellite mapping, and zoom to place the results in a geologic or geopolitical context and add visual appeal. To better understand who visits the IEB and why, to include information on demographics and how users perceive the IEB functionality and ability to meet their needs, we conducted a pop-up user survey on the IEB from 25 January to 21 February 2018. We received 495 useable responses from 58 countries, with 40% of the total respondents from the United States. The largest demographic consists of interested citizens who are 55 yr of age or older and have a high school education. We also find that visitors come to the IEB to learn about earthquakes for two main reasons: for their own personal knowledge or because expanding their knowledge is important to their research or work in a professional context. We also find a dramatic increase in survey respondent activity following the 16 February 2018 M 7.2 Oaxaca, Mexico, earthquake, with many respondents interested in finding more information about recent earthquake events that affect them or their family. Our observations indicate that users are successful and satisfied with the ease of use and amount of time spent on the IEB to find answers to their questions about earthquakes. The most beneficial feature of the IEB as identified by survey respondents is the spatiotemporal visual display of real earthquake data.

Full textAbstract:
Southern California’s hidden treasures include two church interiors containing elements designed by Alfredo Ramos Martinez (1871–1946). This Mexican-born artist trained in France, returned to take an activist role in Mexican revolutionary culture, and migrated to the United States in 1929. For sixteen years, his talents were in demand among members of the Hollywood elite. In 1934, he produced the fresco murals at the Santa Barbara Cemetery Chapel, a jewel of Spanish Revival architecture. His images crossed over traditional boundaries between the sacred and the profane. He created odes to human rights and suffering humanity, depicting Christ and his mother as indigenous peasants with dark-skinned New World ethnicity. A decade later in 1946, Ramos sketched designs for his final projects at St. John the Evangelist Church in Los Angeles: a series of stained glass windows representing fourteen multiethnic saints as well as incomplete oil painted Stations of the Cross that recall his earlier pictures of suffering humanity. The architectural setting—a modernist church with stripped-down forms and materials of concrete, steel, and neon—announces a radically transformed post-war industrial culture. The contrast of these two aesthetics, the Spanish Revival and the modernist, demonstrates an evolution in liturgical forms as Californians came to grips with global migrations and an evolving modernist identity.

Full textAbstract:
This essay aims at connecting child and youth care (CYC) to U.S. teacher education, educator pathways, and schooling in the United States. Further, this essay addresses Wolfgang Vachon’s call to push the boundaries of CYC, specifically in queering the field. I offer ways U.S. teacher education contexts and practices might be considered as guidance in supporting queer identities in CYC. I posit that there is a corporeal pedagogy that queer CYC practitioners enact that is effected beyond simple visibilities, and that they sustain their own identities and survival in CYC spaces through this practice. I also offer a testimonio of my practice as an out genderqueer, Chinese Mexican teacher educator who works in U.S. field-based teacher training and after-school CYC spaces. Further, I argue for critical engagement with curricula and field work in our training programs and make a call for training programs to support CYC practitioners in sustaining their queer identities. Finally, I argue for a need to continue to archive — and perhaps rescue — the practices and collective memories of queer CYC practitioners in order to advance a meaningful sustaining of queer identities in CYC.

Full textAbstract:
Laura Esquivel's 1989 Mexican novel Like Water for Chocolate, neither translated into English nor published in the United States until 1992, was both an American bestseller and the basis for an acclaimed motion picture. Interestingly, though, Esquivel's work also seems to be receiving glimmers of the type of critical attention generally reserved for less “popular” works. Two particular critical studies composed in English, one by Kathleen Glenn and the other by Cecelia Lawless, have been devoted entirely to Chocolate, and both of the scholar/authors grace the faculties of reputable American institutions of higher learning. As a student whose academic experience has been replete with elitist attitudes and expressions of disdain for anything that smacks of an appeal to the masses, I was intrigued by Chocolate for this very reason; in a world where scholarly boundaries seem unalterably fixed, a work that appears capable of crossing these rigid lines is, in my opinion, both rare and admirably refreshing. In my studies, I have often hoped for more communication between “popular” and “scholarly” literature; Esquivel's novel provides not only opportunities for this dialogue but for other cross-genre discussions as well.

Full textAbstract:
ABSTRACTDespite advocacy of landscape approaches in cultural resource management (CRM) and critiques of the site concept, CRM data collection methods in the western United States continue to focus on individual archaeological sites as units of observation, analysis, and management. The transect-recording unit (TRU) method strikes a balance between conventional site-based recording methods and site-less survey approaches by dividing survey space into a grid of uniformly sized cells for recording all cultural manifestations observed across a survey area. TRU survey generates site boundaries required by CRM regulations while retaining a fine-grained spatial framework for landscape-level research and management. This article discusses the technical requirements of the TRU system and its potential for improving landscape-level research and management. Advances in digital recording technologies and analysis techniques render the method efficient and effective in identifying cultural resource distributions and characteristics otherwise obscured by conventional approaches. The research and management potential of the TRU system is illustrated through identification and interpretation of precontact foot trails in New Mexico's Tularosa Basin. These trails are essentially invisible during pedestrian survey but are readily identifiable as linear patterns using aggregated landscape-scale TRU survey data from multiple survey projects, providing novel insight into precontact routes of movement and exchange.

Full textAbstract:
Brian K. Vaughan’s and Marcos Martin’s science fiction comics series, Barrier (2015‐18), is a five-issue story set on the US-Mexican border and contributing to the continuing public discourse surrounding undocumented immigration in the United States. First appearing as a webcomic on Vaughan’s Panel Syndicate website and later published in comic book form by Image Comics, Barrier’s story of two characters, a Honduran refugee and a Texas rancher who struggle with and eventually come to rely on one another, depicts linguistic and cultural boundaries and borders, as well as the frustration and hostility they can generate. As comics, Barrier’s very medium works by means of crossing boundaries and borders: binaries (like word and image) are complicated if not subverted, and the borders of each panel remain closed yet open for sequential art to function as a medium for narrative. Moreover, as a bilingual webcomic crossing into print yet all but encouraging an ongoing virtual engagement through web searches and Google Translate, the series demands further creative energy from the reader in reimaging various barriers, borders and positions of liminality. Although stories that represent various kinds of borders (social, cultural and geopolitical) and various ways of establishing, challenging, crossing or deconstructing borders are frequently found in graphic narratives, Barrier demonstrates the south-west border to be one the medium of comics is especially suited to explore. Barrier is a work that takes as its very subject, to borrow a phrase from Ramzi Fawaz, ‘spatially drawn analogies’ in order to engage graphically matters of genuine political import. In doing so, Barrier not only reflects obliquely on its own form, but also engages creatively with one of the most politically and culturally contested spaces in contemporary US culture.

AbstractMarine boundaries between states of the United States and between the states and the United States have a long and contentious history. Disputes have arisen between states separated by a river and between states in extending their land boundaries seaward. Especially since the Submerged Lands Act of 1953, disputes between states and the federal United States over title to valuable resources in the three-mile coastal area measured from the shoreline have been sharp and continuous. The legal basis for the delimitation of marine zones, including common law, statutes and international law, has been explored, indicating the reliance of courts on all three sources plus equitable principles.
