Abstract:

Purpose – The purpose of this paper is to determine which socioecological factors encourage rural women to participate in mammographies rather than avoiding taking the test. Design/methodology/approach – The study mainly uses data from the 2007 Rural Households Evaluation Survey (ENCEL-2007). These crossover data are analyzed using the framework proposed in the Spatial-Interaction Model of Mammography Use (SIMMU), through a three-level logistic regression model to examine the likelihood that a woman will choose to participate in a mammography. Findings – At the woman-household level, the completion of the Pap smear and the asset index is the strongest determinant of mammography participation. Obtaining preventive medicine services or being enrolled in the Popular Insurance System prevent women from undergoing screening. At the interpersonal level, the probability of screening use decreases with lower social coverage. At the intermediate level, availability of health centers is negatively related to the use of screening. Research limitations/implications – The study fails to take into account the fact that women’s propensity to have a mammography may vary over time relatively to life changes. Moreover, findings were restricted to women ages from 40 to 49 and limited due to the lack of published data or data quality issues. Practical implications – The results of this research can give health planners, policymakers and social marketers a platform for how to approach social change and promote the cancer screening health behavior through the marketing mix (price, place, promotion and product) in the design of their programs. Originality/value – In addition to be informative and persuasive with people to change their behavior, this paper also seeks to provide a direction for using commercial marketing tools through social marketing to “sell” the health behavior. Due to target population variation, this paper addresses the health behavior change strategy by audience segmentation, regarded as essential to successful health communication campaigns.

Abstract:

In September 2011, all elementary schools in British Columbia, Canada began providing a full school day of kindergarten to its children. Prior to this, the majority of children experi-enced kindergarten in a half day for-mat, while the province provided a full day to children from “certain pop-ulations” of ethnicity, language, and ability. Supporters of the change pro-fess that a full day of kindergarten can be beneficial for all children, which will subsequently benefit the province in general. This paper aims to gain insight into how the contemporary discourses in early childhood educa-tion in relation to full day kinder-garten influence the racialized experi-ences of British Columbia's young children of colour. A textual analysis was conducted on the Full Day Kindergarten Program Guide (2010) from the lens of Critical Race Theory. The guide's ambiguous use of the con-cept of “culture” is highlighted.

Abstract:

The purpose of this paper is to evaluate the usefulness of prefer-ence-based segmentation in understanding food-related behavior among Vietnamese teenagers. A sample of 413 teenagers in second-ary and high schools in three different regions is used. Their prefer-ences for 36 common Vietnamese dishes are evaluated. Four seg-ments based on their preferences are identified, including food likers (29%), poultry dislikers (27%), seafood dislikers (19%), and pork dislikers (25%). Differences between segments are profiled by a di-verse set of variables including consumption frequencies, food choice motives, attitudinal variables, and socio-demographic varia-bles. Dish preferences appear to be an appropriate basis for segmen-tation of Vietnamese adolescents. The differences found across the clusters for the differentiating variables can provide the basis for developing marketing strategies to target different segments, and also theoretical and practical implications are accordingly discussed.

Abstract:

A new genus and species are described and figured from the eastern pampas of Tandil, Argentina. Aenarete roigi Engel & Gonzalez, new genus and species, is quite similar to Spinolapis Moure (here used in a restricted sense), occurring in southern Chile, and particularly Patagoniapis Engel, new genus (type species: Pasiphae cyanea Cockerell) from further southward in Argentina (Rio Negro to Tierra del Fuego). The genus is distinguished from these two genera and other South American “paracolletines”. Given the employment of different concepts for “paracolletine” genera herein and in recent published works relative to the classification outlined by Michener, a revised key to these groups is appended based on the genera as envisioned by the authors. This necessitates making available the following new taxa (eight new subtribes, 20 new genera, 13 new subgenera): Aageocolletes Engel, new genus; Aglaocolletes Engel, new genus; Asciocolletes Engel, new genus; Baeocolletina Engel, new subtribe; Bicolletopsis Engel, new subgenus of Bicolletes Friese; Calloproctus Engel, new genus; Chilicolletina Engel, new subtribe; Chrysopasiphae Engel, new genus; Conospermapis Engel, new genus; Cyanopasiphae Engel, new subgenus of Bicolletes; Cygnella Engel, new subgenus of Euryglossidia Cockerell; Cyranocolletes Engel, new genus; Damocrateia Engel, new genus; Donovanapis, new subgenus of Leioproctus Smith; Eremocolletes Engel, new genus; Erythropasiphae Engel, new subgenus of Bicolletes; Hexaproctus Engel, new genus; Houstoniella Engel, new subgenus of Eremocolletes; Kanakapis Engel, new subgenus of Lamprocolletes Smith; Leucopasiphae Engel, new subgenus of Perditomorpha Ashmead; Lonchorhynchina Engel & Gonzalez, new subtribe; Manocolletes Engel, new subgenus of Euryglossidia; Machaerocolletes Engel, new genus; Maoricolletes Engel, new subgenus of Leioproctus; Maynardapis Engel, new genus; Nanopasiphae Engel, new genus; Niltoniina Engel, new subtribe; Notinopasiphae Engel, new subgenus of Euryglossidia; Packercolletes Engel, new genus; Perditomorphina Engel, new subtribe; Phenacolletina Engel, new subtribe; Rhamphocolletes Engel, new genus; Ruzopria Engel, new subgenus of Belopria Moure; Sarocolletidion Engel, new genus; Spinolapina Engel, new subtribe; Sthenele Engel, new genus; Stilbopasiphae Engel, new genus; Stoclele Engel, new subgenus of Lamprocolletes; Torocolletina Engel, new subtribe; Walkerapis Engel, new genus; Zyzzocolletes Engel, new genus.

Abstract:

This is the third part of a series on various taxonomic matters regarding the Neotropical stingless bee genus Scaptotrigona Moure (Apinae: Meliponini). Here, an infrageneric classification is established, with Sakagamilla Moure resurrected for the tubiba group, while Scaptotrigona Moure, s.str., encompasses the postica group. A key to subgenera is presented and five new subgenera are established: Eoscaptotrigona Engel, new subgenus; Dasytrigona Engel, new subgenus; Gymnotrigona Engel, new subgenus; Baryorygma Engel, new subgenus; and Astegotrigona Engel, new subgenus. The former bipunctata species group is considered to embody two unrelated groups and species of the luteipennis group also belong among these. Six new species are described, two of which would have formerly been included in the bipunctata group, and the remainder belong to the depilis group: Scaptotrigona (Eoscaptotrigona) totobi Engel, new species, from Venezuela and Colombia; S. (Gymnotrigona) psile Engel, new species, from Venezuela; S. (Gymnotrigona) aurantipes Engel, new species, from Venezuela; S. (Gymnotrigona) nuda Engel, new species, from Bolivia; S.

Abstract:

AbstractLet n be a positive integer. We say that a group G is an {(n+\frac{1}{2})}-Engel group if it satisfies the law {[x,{}_{n}y,x]=1}. The variety of {(n+\frac{1}{2})}-Engel groups lies between the varieties of n-Engel groups and {(n+1)}-Engel groups. In this paper, we study these groups, and in particular, we prove that all {(4+\frac{1}{2})}-Engel {\{2,3\}}-groups are locally nilpotent. We also show that if G is a {(4+\frac{1}{2})}-Engel p-group, where {p\geq 5} is a prime, then {G^{p}} is locally nilpotent.

Abstract:

Using known results on 4-Engel groups one can see that a 4-Engel group is locally nilpotent if and only if all its 3-generator subgroups are nilpotent. As a step towards settling the question whether all 4-Engel groups are locally nilpotent we show that all 2-generator 4-Engel groups are nilpotent.

Abstract:

Three new species of the augochlorine bee genus Stilbochlora Engel et al. (Halictinae: Augochlorini) are described and figured from Peru. The new species are distinct from the type species, Stilbochlora eickworti (Engel et al.), in the more densely and extensively striate propodea, and can be distinguished from each other on the basis of propodeal sculpturing and coloration. The new taxa are: S. graceae Engel, new species; S. kateae Engel, new species; and S. wedmanorum Engel, new species. A key is provided to the species of Stilbochlora.

Abstract:

Among the many inclusions from the exceptionally rich fossiliferous amber of Zhangpu, China (Middle Miocene: Langhian), stingless bees (Apinae: Meliponini) are particularly common, analogous to the merely slightly older amber sites of Mexico and the Dominican Republic. While there is a large number of workers in Zhangpu amber, only two species are represented. The systematics and morphology of the tribe Meliponini is outlined, including a revision to terms of orientation and direction when discussing surfaces and features of appendages, all in order to better discuss the traits of the fossils as well as place them into a broader context in the global systematics of stingless bees. The two amber species are representative of two Old World genera of Meliponini: Tetragonula Moure and Austroplebeia Moure. While the former is widespread across southern Asia, Malesia, Papuasia, and Australia, the latter is today known only from New Guinea and Australia. Neither genus occurs in the environs of Zhangpu today. Tetragonula (Tetragonula) florilega Engel, new species, is a generally typical species of the subgenus although it intermingles traits otherwise found in two large species groups of non-Australian Tetragonula s.str. The species of Austroplebeia from Zhangpu is sufficiently distinct to place in a new subgenus, Anteplebeina Engel. Austroplebeia (Anteplebeina) fujianica Engel, new species, shares a long list of character states with Austroplebeia s.str., including the presence of yellow maculation on the face, mesoscutum, mesoscutellum, and metepisternum, found only in this clade among Asiatic Meliponini. Nonetheless, the species differs in the length of the malar space and various features of wing venation. Keys are provided to the genera in Zhangpu amber and the subgenera of both genera. The diversity of stingless bees in amber is discussed, as well as the presence of these two fossils in the Middle Miocene of mainland Asia in relation to prior divergence time estimates, phylogenetic relationships, as well as the paleogeography of the region and potential biogeographic hypotheses. The biological association of stingless bees with resins, particularly the collection of dipterocarp resins, is discussed as Zhangpu amber is a Class II resin likely produced by an extinct species of Dipterocarpaceae (Malvales). Also discussed are the ecological preferences of modern Tetragonula and Austroplebeia relative to the reconstructed paleoenvironment of the Zhangpu amber rainforest. Emendations to the classification of Meliponini are appended, with the following new taxa proposed: Atrichotrigona Engel, new subgenus of Axestotrigona Moure; Lispotrigona V.H. Gonzalez & Engel, new subgenus of Nannotrigona Cockerell; Asperplebeia Engel, new genus; Nanoplebeia Engel, new subgenus of Plebeia Schwarz; Aphaneuropsis Engel, Koilotrigona Engel, Necrotrigona Engel, Dichrotrigona Engel, Nostotrigona Engel, Ktinotrofia Engel, all new subgenera of Trigona Jurine; Chapadapis Engel, new subgenus of Schwarziana Moure. The following higher groups are also established: Hypotrigonina Engel, new sutribe; Heterotrigonitae Engel, new infratribe; Trigoniscitae Engel, new infratribe.

Abstract:

We present some new results on third Engel groups which are motivated by computer calculations but are not dependent on them. They include:• for n > 2 every n-generator third Engel group is nilpotent of class at most 2n – 1;• the fifth term of the lower central series of a third Engel group has exponent dividing 20;• the subgroup generated by fifth powers of elements in a third Engel group is nearly centre-by-metabeliami;and a normal form theorem for freest third Engel groups without elements of order 2.

Abstract:

The tribe Melikertini (Apinae: Corbiculata) is an extinct group of highly eusocial bees presently known only from early to late Eocene deposits of Eurasia. Among melikertine diversity are a suite of species peculiar for their rather dramatic morphological specializations, at least in relation to modern corbiculate Apinae. Here we document two new species of Melikertini and utilize standard X-ray as well as propagation phase contrast synchrotron computed microtomography to further explore these and previously known species, revealing finer details not previously observable from melikertines. Accordingly, some species placed in the genera Melikertes Engel and Succinapis Engel are reëvaluated. Three new genera are characterized, as well as some further facial modifications not previously known for the tribe. New taxa and taxonomic changes presented are: Aethemelikertes emunctorii Engel, new genus and species; Haidomelikertes uraeus Engel, new genus and species; H. proboscidea (Engel), new combination; Amelikertotes Engel, new genus; Amelikertotes clypeata (Engel), new combination. Additionally, new records and taxonomic notes on other Baltic amber and Eocene bees are appended, with the following nomenclatural changes established: Palaeomacropis Michez & Nel is recognized as a megachiline rather than a melittid, and is transferred to Megachilinae where it is a new junior synonym of Ctenoplectrella Cockerell (new synonymy); Ctenoplectrella eocenica (Michez & Nel), new combination; a key is provided to species of Ctenoplectrella; Thaumastobombina Engel, new subtribe in Electrapini; Thnetobombus Engel, new subgenus in Protobombus Cockerell; Mesomelissa Engel, new subgenus in Electrapis Cockerell; Electrapis (Euglossopteryx) biesmeijeri (De Meulemeester et al.), new combination. A list of Eocene bees is appended.
