The location of executive suites and business centers in the United States: an exploratory analysis

Increasingly, corporate occupiers seek more flexible ways of meeting their accommodation needs. One consequence of this process has been the growth of the executive suite, serviced office or business centre market. This paper, the final report of a research project funded by the Real Estate Research Institute, focuses upon the geographical distribution of business centers offering executive suites within the US. After a brief review of the development of the market, the paper examines the availability of data, provides basic descriptive statistics of the distribution of executive suites by state and by metropolitan statistical area and then attempts to model the distribution using demographic and socio-economic data at MSA level. The distribution reflects employment in key growth sectors and the position of the MSA in the urban hierarchy. An appendix presents a preliminary view of the global distribution of suites.

Behavioral suites mediate group-level foraging dynamics in communities of tropical stingless bees

Competition for floral resources is a key force shaping pollinator communities, particularly among social bees. The ability of social bees to recruit nestmates for group foraging is hypothesized to be a major factor in their ability to dominate rich resources such as mass-flowering trees. We tested the role of group foraging in attaining dominance by stingless bees, eusocial tropical pollinators that exhibit high diversity in foraging strategies. We provide the first experimental evidence that meliponine group foraging strategies, large colony sizes and aggressive behavior form a suite of traits that enable colonies to improve dominance of rich resources. Using a diverse assemblage of Brazilian stingless bee species and an array of artificial ""flowers"" that provided a sucrose reward, we compared species` dominance and visitation under unrestricted foraging conditions and with experimental removal of group-foraging species. Dominance does not vary with individual body size, but rather with foraging group size. Species that recruit larger numbers of nestmates (Scaptotrigona aff. depilis, Trigona hyalinata, Trigona spinipes) dominated both numerically (high local abundance) and behaviorally (controlling feeders). Removal of group-foraging species increased feeding opportunities for solitary foragers (Frieseomelitta varia, Melipona quadrifasciata and Nannotrigona testaceicornis). Trigona hyalinata always dominated under unrestricted conditions. When this species was removed, T. spinipes or S. aff. depilis controlled feeders and limited visitation by solitary-foraging species. Because bee foraging patterns determine plant pollination success, understanding the forces that shape these patterns is crucial to ensuring pollination of both crops and natural areas in the face of current pollinator declines.

Morphological and compositional variations of zircon and their metallogenetic implications: the example of the Jamon, Serra dos Carajás and Velho Guilherme suites, Amazonian Craton

Zircões de granitos das Suítes Jamon (SJ), Serra dos Carajás (SSC) e Velho Guilherme (SVG) foram estudados em MEV por meio de imagens de elétrons retroespalhados e catodoluminescência e análises pontuais por EDS. Granitos e greisens da SVG apresentam zircões dominantemente anédricos, alterados e intensamente corroídos, enriquecidos em Hf e com as mais baixas razões Zr/Hf, as quais nos granitos tendem a decrescer no sentido das fácies mais evoluídas. Zircões da SJ são euédricos a subédricos, zonados e pouco alterados, comparativamente empobrecidos em Hf e com as mais elevadas razões Zr/Hf, indicando potencial reduzido para geração de mineralização estanífera. Zircões dos granitos da SSC são subédricos a anédricos, alterados e corroídos e com conteúdos de Hf e razões Zr/Hf intermediárias a dos zircões das SJ e SVG. Granitos da SVG com mineralizações de Sn, W e Ta apresentam zircões com razões Zr/Hf entre 7 e 22. Conclui-se que razões desta ordem podem ser utilizadas como guia prospectivo de granitos especializados. Por outro lado, zircões de greisens associados ao Granito Cigano da SSC apresentaram razão Zr/Hf média em torno de 23, porém nenhuma cassiterita foi encontrada nessas rochas. Isto indica que estes zircões preservaram sua assinatura magmática original. O estudo desenvolvido permitiu distinguir as três suítes graníticas em termos de composição de zircão, e mostrou a importância da assinatura geoquímica desse mineral, sobretudo da razão Zr/Hf, na identificação de granitos especializados. Análises de zircões por MEV-EDS podem, portanto, ser utilizadas na avaliação preliminar do potencial metalogenético de granitos estaníferos.

MODEL PARTITIONS AND COMPACT TEST CASE SUITES

We present a generalized test case generation method, called the G method. Although inspired by the W method, the G method, in contrast, allows for test case suite generation even in the absence of characterization sets for the specification models. Instead, the G method relies on knowledge about the index of certain equivalences induced at the implementation models. We show that the W method can be derived from the G method as a particular case. Moreover, we discuss some naturally occurring infinite classes of FSM models over which the G method generates test suites that are exponentially more compact than those produced by the W method.
