Fiber flax in oregon

Russia, Poland and the Baltic countries account for about 90% of the world’s production of fiber flax, and prior to 1940, 90% of the raw fiber used in the United States was imported from Europe. Today domestic production in the Willamette Valley of Oregon represents a $3 million dollar industry.     

Is There a Lag Globally in Overweight Trends for Children Compared with Adults?

Objective: To determine relative trends in prevalence for overweight for adults compared with children across high‐income countries (Australia, United Kingdom, and United States), middle‐income countries (Brazil and Russia), and low‐income countries (China and Indonesia). Research Methods and Procedures: Extant nationally representative survey data from 1971 to the present are used. Prevalence of overweight for adults ≥18.0 years of age and children 6.0 to 17.9 years of age were used. Absolute and relative annual rates of change in prevalence of overweight in children and adults were the key outcomes. Results: Absolute rates of increase in overweight were higher among adults than among children in all studied countries except Australia. However, relative rates of increase in overweight indicate faster increases in overweight among children in Brazil, China, and the three high‐income countries. As a result, the relative excess of overweight among adults, seen initially in all countries, increased in Indonesia and Russia, but it decreased in Australia, Brazil, China, United Kingdom, and United States. In Brazil, time trends indicate an acceleration in the annual rate of change in overweight for children and a deceleration for adults, whereas in the United States, the increase in overweight shows acceleration for both children and adults. Discussion: In absolute terms, overweight increased faster among children than adults only in Australia; however, the relative gap between children and adults is closing in four additional countries, Brazil, China, the United Kingdom, and the United States.     

"Race"—Still an Issue for Physical Anthropology? Results of Polish Studies Seen in the Light of the U.S. Findings

The racial paradigm, which became rooted in physical anthropology at its very beginning, was, for decades, treated as a concept needing no verification. It was only in the mid-20th century that the first attempts were made to question the usefulness of the race concept in describing our species variation. Since then, an ever growing number of anthropologists, particularly in the United States, have rejected the concept (nearly seventy percent in 1999). In Poland, the situation is different—in the 2001 study, the race concept was rejected by only 25 percent; the remaining respondents differing widely as to the accepted meaning of race. Unlike the U.S. anthropologists, Polish anthropologists tend to regard race as a term without taxonomic value, often as a substitute for population. The discrepancy may stem from differences in the traditions of anthropological schools, the differing sociopolitical histories, education, semantics, and possible attitudinal factors.

Editorial

As Zoological Research enters its 33rd year of publication,let us reflect back on the last three decades of dramatic change to China and the scientific community. In the latter half of the 20th century, scientific research was almost exclusively published in the United States or Europe. We started Zoological     

Ergot—a blessing and a scourge

Ergot, the black mass of a particular fungus on cereal grains, especially rye, was the cause of frightful epidemics in Europe more than a thousand years ago, and the ingested contaminated grain has occasioned disease in Russia as late as 1927 and in the United States a generation earlier. Medicinally administered, however, it provides a very important drug in the science of obstetrics.     

Beyond borders: on the influence of the creationist movement on the educational landscape in the USA and Russia

This paper provides a detailed look at how creationism originated in the United States and then explores how this evangelical trend was exported to Russia by American missionaries following the fall of the USSR. The comparison between these two countries is particularly interesting since the rivalry between the US and the USSR during the race to space caused both countries to revamp their science education. Yet, while political interests led both governments to focus on science education, creationist activities were simultaneously focused on diminishing the coverage of evolution in science classrooms. Now, decades following Sputnik’s trip to space, the urgency to strengthen scientific learning has waned, while creationists are still equally focused on removing scientific naturalism in favor of supernatural explanations for the origin of species. This paper thus offers an in-depth look at which groups are currently responsible for promoting creationist activities in the US and in Russia and which groups are working hard to keep supernatural doctrines out of science curriculum.     

Polish Glomales

Spores of Acaulospora dilatata and Scutellospora dipurpurascens found in Poland are described and illustrated and their occurrence and distribution are characterized and mapped. Spores of Acaulospora dilatata from Poland do not differ from those originally described in the United States of America. The germination shield found in a number of spores is described and illustrated, and compared with that occurring in members of the genus Scutellospora. Acaulospora dilatata was found in five of the 303 soil samples taken from around the roots of Ammophila arenaria colonizing maritime sand dunes of the Sowinski National Park. Polish specimens of S. dipurpurascens are similar in size, wall structure, and reaction in Melzer's reagent to those described from the type localized in the United States of America. However, some spores from Poland have a thicker wall, greater sporogenous cells, and are somewhat darker coloured. They were recovered from 34 soils sampled from forests, gardens, sand dunes, and both cultivated and uncultivated soils. S. dipurpurascens was commonly associated with different plants of the Hel Peninsula and occurred regularly among the roots of Ammophila arenaria growing in the Slowinski National Park. Both species were found for the first time in Poland and are probably new to Europe.     

Polish Lebensraum: the colonial ambition to expand on racial terms

Lebensraum – the space a state believes is required for its natural expansion – has a pivotal role in the global expansion projects. Whenever this concept is discussed, it is almost exclusively reduced to the Imperial Russia’s domination of less-stately countries in Central and Eastern Europe; the British exploration and colonization of territories in Africa and Asia; the French settlements in parts of the Caribbean Islands and Africa; the German experimentation in South-West Africa, and the Dutch seaborne competing with the Spanish and Portuguese’s expansionism. Study related to Poland’s attempted acquisition of colonial territories outside Europe is rarely discussed. Drawing on the activities of the Polish Colonial Society, this article contends that the building blocks of colonization were not confined solely to European imperial powers. As colonization forged ahead in the twentieth century, Poland seemed to be the country where colonialism played a significant role in both national and transnational politics.     

Current Views of European Anthropologists on Race: Influence of Educational and Ideological Background

ABSTRACT  Significant differences in views on race (once a core anthropological concept) occur between scientists from different countries. In light of the ongoing race debate, we present the concept's current status in Europe. On three occasions in 2002–03, we surveyed European anthropologists' opinions toward the biological race concept. The participants were asked whether they agreed that there are biological races within the species Homo sapiens . A dependence was sought between the type of response and several factors. Three of these factors—country of academic education, discipline, and age—were found to be significant in differentiating the replies. Respondents educated in Western Europe, physical anthropologists, and middle-aged persons reject race more frequently than respondents educated in Eastern Europe, people in other branches of science, and those from both younger and older generations. The survey shows that the views of anthropologists on race are sociopolitically (ideologically) influenced and highly dependent on education.

Forensic entomology and main challenges in Brazil

Apart from an early case report from China (13th century), the first observations on insects and other arthropods as forensic indicators were documented in Germany and France during mass exhumations in the 1880s by Reinhard, who is considered a co-founder of the discipline. After the French publication of Mégnin's popular book on the applied aspects of forensic entomology, the concept quickly spread to Canada and United States. At that time, researchers recognized that the lack of systematic observations of insects of forensic importance jeopardized their use as indicators of postmortem interval. General advances in insect taxonomy and ecology helped to fill this gap over the following decades. After World Wars, few forensic entomology cases were reported in the scientific literature. From 1960s to the 1980s, Leclercq and Nuorteva were primarily responsible for maintaining the method in Central Europe, reporting isolated cases. Since then, basic research in the USA, Russia and Canada opened the way to the routine use of Entomology in forensic investigations. Identifications of insects associated with human cadavers are relatively few in the literature of the Neotropical region and have received little attention in Brazil. This article brings an overview of historic developments in this field, the recent studies and the main problems and challenges in South America and mainly in Brazil.     

Handheld computers for data entry: high tech has its problems too

Contradictory statements about the non-steroidal anti-inflammatory drugs from the European Medicines Agency and the United States Food and Drug Administration have raised questions about whether regulatory decisions are evidence-based. For the selective COX-2 inhibitors, there are clear contraindications and warnings in Europe, but only a vaguely worded Black Box warning in the United States. All the non-selective agents are given an almost "clean bill of health" in Europe, while all of them are judged to have a similar risk-benefit ratio as celecoxib in the United States. The regulatory agencies have failed to recognize the clinical trial evidence that the risk of cardiovascular events varies substantially among the non-selective agents, with diclofenac carrying the highest risk of harm.     

Comparing the prevalence of rheumatic diseases in China with the rest of the world

Geographic or ethnic differences in the occurrence of disease often provide insights into causes of disease and possible opportunities for disease prevention. Persons in China appear to have a consistently lower prevalence of rheumatoid arthritis and fibromyalgia than persons in the United States and Europe; reasons for these prevalence differences might include genetic differences, differences in environmental exposures or a combination of both. With increasing obesity, gout is becoming endemic in China. Finally, symptomatic knee osteoarthritis is extremely common in China and constitutes a major public health problem there.     

"Race" and the Construction of Human Identity

Race as a mechanism of social stratification and as a form of human identity is a recent concept in human history. Historical records show that neither the idea nor ideologies associated with race existed before the seventeenth century. In the United States, race became the main form of human identity, and it has had a tragic effect on low-status "racial" minorities and on those people who perceive themselves as of "mixed race." We need to research and understand the consequences of race as the premier source of human identity. This paper briefly explores how race became a part of our culture and consciousness and argues that we must disconnect cultural features of identity from biological traits and study how "race" eroded and superseded older forms of human identity. It suggests that "race" ideology is already beginning to disintegrate as a result of twentieth-century changes.     

BEHAVIORAL EVIDENCE FOR FRUIT ODOR DISCRIMINATION AND SYMPATRIC HOST RACES OF RHAGOLETIS POMONELLA FLIES IN THE WESTERN UNITED STATES

The recent shift of Rhagoletis pomonella (Diptera: Tephritidae) from its native host downy hawthorn, Crataegus mollis, to introduced domesticated apple, Malus domestica, in the eastern United States is a model for sympatric host race formation. However, the fly is also present in the western United States, where it may have been introduced via infested apples within the last 60 years. In addition to apple, R. pomonella also infests two hawthorns in the West, one the native black hawthorn, C. douglasii, and the other the introduced English ornamental hawthorn, C. monogyna. Here, we test for behavioral evidence of host races in the western United States. through flight tunnel assays of western R. pomonella flies to host fruit volatile blends. We report that western apple, black hawthorn, and ornamental hawthorn flies showed significantly increased levels of upwind‐directed flight to their respective natal compared to nonnatal fruit volatile blends, consistent with host race status. We discuss the implications of the behavioral results for the origin(s) of western R. pomonella, including the possibility that western apple flies were not introduced, but may represent a recent shift from local hawthorn fly populations.     

Decoupling Analysis of Four Selected Countries

We examine decoupling conditions of domestic extraction of materials, energy use, and sulfur dioxide (SO₂) emissions from gross domestic product (GDP) for two BRIC (Brazil, Russia, India and China) countries (i.e., China and Russia) and two Organisation for Economic Co‐operation and Development (OECD) countries (Japan and the United States) during 2000–2007, using a pair of decoupling indicators for resource use (D_r) and waste emissions (D_e) and the decoupling chart, which can distinguish between absolute decoupling, relative decoupling, and non‐decoupling. We find that (1) during 2000–2007, decoupling between environmental indicators and GDP was higher in the two OECD countries as compared with the two BRIC countries. The key reason is that these countries were in different development stages with different economic growth rates. (2) Changes in environmental policies can significantly influence the degree of decoupling in a country. (3) China, Japan, and the United States were more successful in decoupling SO₂ emissions from GDP than in decoupling material and energy use from GDP. The main reason is that, unlike resource use, waste emissions (e.g., SO₂ emissions) can be reduced by effective end‐of‐pipe treatment. (4) The decoupling indicator is different from the changing rate of resource use and waste emissions. If two countries have different GDP growth rates, even though they may have similar values using the decoupling indicator, they may show different rates of change for resource use and waste emissions.

Why single men might abhor foreign cultures

In contrast to cues to women's mate value (youth and physical attractiveness), many qualities that men display in lekking are socially and culturally specific. We predict that, for this reason, men avoid exposure to foreign cultures, but such xenophobia should cease once they are married (especially since the presence of their wives can function as a cross-culturally meaningful lekking device). Analyses of data from Europe and the United States confirm our predictions.     

Dialectics of Race and Nationality: Contradictions and Philadelphia Working-Class Youth

This article explores the concept of dialectical contradictions as it relates to individual understandings of intergroup relations in the United States. The ways that working-class white youth and adults combine contradictory experience and ideology in their behavior and belief systems regarding foreign-born residents and people of color are detailed. By describing conflict and cooperation among youth from different races and nationalities, the discussion shows the relationship between the concept of dialectics and race relations as they are played out in day-to-day interactions in a Philadelphia neighborhood and Polish nationalities parish school.     

Wolf population genetics in Europe: a systematic review,meta‐analysis and suggestions for conservation and management

The grey wolf (Canis lupus) is an iconic large carnivore that has increasingly been recognized as an apex predator with intrinsic value and a keystone species. However, wolves have also long represented a primary source of human–carnivore conflict, which has led to long‐term persecution of wolves, resulting in a significant decrease in their numbers, genetic diversity and gene flow between populations. For more effective protection and management of wolf populations in Europe, robust scientific evidence is crucial. This review serves as an analytical summary of the main findings from wolf population genetic studies in Europe, covering major studies from the ‘pre‐genomic era’ and the first insights of the ‘genomics era’. We analyse, summarize and discuss findings derived from analyses of three compartments of the mammalian genome with different inheritance modes: maternal (mitochondrial DNA), paternal (Y chromosome) and biparental [autosomal microsatellites and single nucleotide polymorphisms (SNPs)]. To describe large‐scale trends and patterns of genetic variation in European wolf populations, we conducted a meta‐analysis based on the results of previous microsatellite studies and also included new data, covering all 19 European countries for which wolf genetic information is available: Norway, Sweden, Finland, Estonia, Latvia, Lithuania, Poland, Czech Republic, Slovakia, Germany, Belarus, Russia, Italy, Croatia, Bulgaria, Bosnia and Herzegovina, Greece, Spain and Portugal. We compared different indices of genetic diversity in wolf populations and found a significant spatial trend in heterozygosity across Europe from south‐west (lowest genetic diversity) to north‐east (highest). The range of spatial autocorrelation calculated on the basis of three characteristics of genetic diversity was 650?850 km, suggesting that the genetic diversity of a given wolf population can be influenced by populations up to 850 km away. As an important outcome of this synthesis, we discuss the most pressing issues threatening wolf populations in Europe, highlight important gaps in current knowledge, suggest solutions to overcome these limitations, and provide recommendations for science‐based wolf conservation and management at regional and Europe‐wide scales.     

Hawthorn-infesting populations of Rhagoletis pomonella in Mexico and speciation mode plurality

Categorizing speciation into dichotomous allopatric versus nonallopatric modes may not always adequately describe the geographic context of divergence for taxa. If some of the genetic changes generating inherent barriers to gene flow between populations evolved in geographic isolation, whereas others arose in sympatry, then the mode of divergence would be mixed. The apple maggot fly, Rhagoletis pomonella, has contributed to this emerging concept of a mixed speciation mode "plurality." Genetic studies have implied that a source of diapause life-history variation associated with inversions and contributing to sympatric host race formation and speciation for R. pomonella in the United States may have introgressed from the Eje Volcanico Trans Mexicano (EVTM; a.k.a. the Altiplano) in the past. A critical unresolved issue concerning the introgression hypothesis is how past gene flow occurred given the current 1200-km disjunction in the ranges of hawthorn-infesting flies in the EVTM region of Mexico and the southern extreme of the U.S. population in Texas. Here, we report the discovery of a hawthorn-infesting population of R. pomonella in the Sierra Madre Oriental Mountains (SMO) of Mexico. Sequence data from 15 nuclear loci and mitochondrial DNA imply that the SMO flies are related to, but still different from, U.S. and EVTM flies. The host affiliations, diapause characteristics, and phylogeography of the SMO population are consistent with it having served as a conduit for gene flow between Mexico and the United States. We also present evidence suggesting greater permeability of collinear versus rearranged regions of the genome to introgression, in accord with recent models of chromosomal speciation. We discuss the implications of the results in the context of speciation mode plurality. We do not argue for abandoning the terms sympatry or allopatry, but caution that categorizing divergence into either/or geographic modes may not describe the genetic origins of all species. For R. pomonella in the United States, the proximate selection pressures triggering race formation and speciation stem from sympatric host shifts. However, some of the phenological variation contributing to host-related ecological adaptation and reproductive isolation in sympatry at the present time appears to have an older history, having originated and become packaged into inversion polymorphism in allopatry.
