Foreign Countries

For the past forty years there have been virtually no introductions of honeybee stock from foreign countries into Canada or the United States. This has been due to the stringent restrictions on importing honeybees which have been in force since 1922, as a safeguard against the introduction of acarine disease. The mite which is responsible for the disease, Acarapis woodi, is present in many parts of Europe, and has also been reported from Asia, Africa and South America. It has not so far been found in North America, although external mites of the same genus (A. dorsalis and A. externus) are now known to occur fairly commonly throughout Canada and the United States.

The Past

Economic activity accelerated sharply in the United States at the beginning of this year. GDP rose by 1¼ per cent in the first quarter, to a level 3.8 per cent higher than a year earlier. This was the fastest quarterly growth for two years. The acceleration in growth was unexpected given that the present cyclical expansion has now lasted for over seven years. Private sector demand is still continuing to be supported by the sustained appreciation in equity prices over the past three years, and the appreciation of the dollar has helped to hold down the inflationary pressures that are being built up as the labour market begins to tighten. The unemployment rate fell to 4.3 per cent in April, the lowest rate since 1970.

The Past

The fossil record of dinosaurs from the Early Cretaceous of eastern North America is scant, and only a few sediments to the east of the continent are fossiliferous. Among them is the Arundel Formation of the east coast of the United States, which has produced among the best dinosaur faunas known from the Early Cretaceous of eastern North America. The diverse dinosaur fauna of this formation has been thoroughly discussed previously, but few of the dinosaur species originally described from the Arundel are still regarded as valid genera. Much of the Arundel material is in need of review and redescription. Among the fossils of dinosaurs from this formation are those referred to ornithomimosaurs. Here, I redescribe ornithomimosaur remains from the Arundel Formation which may warrant the naming of a new taxon of dinosaur. These remains provide key information on the theropods of the Early Cretaceous of Eastern North America. The description of the Arundel material herein along with recent discoveries of basal ornithomimosaurs in the past 15 years has allowed for comparisons with the coelurosaur Nedcolbertia justinhofmanni, suggesting the latter animal was a basal ornithomimosaurian dinosaur rather than a “generalized” coelurosaur. Comparisons between the Arundel ornithomimosaur and similar southeast Asian ornithomimosaurian material as well as ornithomimosaur remains from western North America suggest that a lineage of ornithomimosaurs with a metatarsal condition intermediate between that of basal and derived ornithomimosaurs was present through southeast Asia into North America, in turn suggesting that such animals coexisted with genera having a more primitive metatarsal morphology as seen in N. justinhofmanni.

Teaching Gap

In The Teaching Gap (1999), James W. Stigler and James Hiebert describe differences between mathematics instruction in Japan and the United States. They attribute some of these differences to a commonly used method of professional development in Japan called lesson study: “The lesson-study process has an unrelenting focus on student learning. All efforts to improve lessons are evaluated with respect to clearly specified learning goals, and revisions are always justified with respect to student thinking and learning” (p. 121). Over the past decade, many groups of educators in North America have implemented various forms of lesson study.

Small Genus

Nothotrichia Flint 1967 is a small genus of infrequently collected microcaddisflies known from Chile and Brazil in South America, Costa Rica in Central America, and the United States in North America. Previously known only from adult specimens, we provide the first description and illustration of a larva in the genus, the larva of N. shasta from California, USA. We provide characters to separate Nothotrichia from other similar genera and an updated key to larval Hydroptilidae modified from that of Wiggins (1996). Larval characters provide additional evidence for the phylogeny and classification of the genus, which we now place tentatively in tribe Ochrotrichiini (subfamily Hydroptilinae).

Oral History Interviews

Across North America, Mennonites are widely regarded to be among the most conservative of Christian groups. But in recent decades, Mennonite understandings of LGBTQ+ identity have transformed faith communities, as the engagement of social media-conscious activists such as Pink Menno have contributed to evolving practices regarding sexual minorities in Mennonite churches. Recent ordinations and the growing visibility of queer ministers, chaplains, and theologians have led to recent schism in Mennonite Church USA, with traditionalists departing the denomination in record numbers. The decentralized nature of Mennonitism has contributed to more inclusive policies in the past two decades, although decentralization also allows exclusionary practices to persist in some churches and institutions. This article draws from oral history interviews with thirty Mennonite theologically trained LGBTQ+ leaders from across the United States and Canada. These narratives demonstrate how—in some sectors of the Mennonite community—queer and non-queer people are accelerating changes in historically homophobic spaces.

At the turn of the nineteenth and twentieth century a large group of Galician Ruthenians emigrated to North America and the United States and Canada, South America - mainly to Argentina and Brazil. Sheptytsky visited North America in 1910. He met with Ukrainian Greek Catholic immigrant communities in the United States and Canada. In 1921, he visited the USA and Canada again. In 1922 he arrived to Argentina and Brazil. He did not conduct open political agitation. However, some of his speeches have an anti-Polish character.

The age distribution of 126 infants and children with disseminated meningococcal disease hospitalized consecutively in Houston between January 1977 and June 1979, and between January 1981 and June 1981 was analyzed and compared with that in the United States as a whole and to that during outbreaks of group B disease in North America and epidemics of group C disease in South America. Eighty-one (64.3%) isolates from Houston cases were serogroup B and 37 (29.4%) were serogroup C Neisseria meningitidis. Children with serogroup C disease were significantly older than those with group B disease (P = .017). Of the children with serogroup B infections, 33% were less than 12 months of age and 8.6% were less than 3 months of age. Of those with serogroup C disease, only 2.7% were less than 3 months of age and the majority (73%) were more than 2 years of age. These age distributions are similar to those reported for the entire United States during endemic periods. In contrast, focal outbreaks of group B meningococcal infection occurred in populations that were significantly older (0.02 > P < .05). Similarly, epidemic disease in South America due to serogroup C strains also occurred in older children when compared with the occurrence of endemic group C disease in the United States (P = .02).

Abstract Ivor Noël Hume is one of the founders of historical archaeology in North America and has long championed the integration of documentary and archaeological evidence for understanding the past. As the chief archaeologist at Colonial Williamsburg for three decades, he directed numerous excavations and literally wrote the book on colonial artifacts. Committed to sharing research findings with the public, he led the way through varied publications and films and developed the first major exhibits about colonial archaeology in the United States. His most well-known project is the exploration and exhibition of the early seventeenth-century Virginia settlement of Martin's Hundred.
