The ground-dwelling ant fauna on the uninhabited Gaja-jima Island, the Tokara Islands, the Ryukyu archipelago, Japan was investigated, which was the first survey on ants of the island. Twenty-three ant species were found during a visit of only eight hours in daytime. Four of them were new records to the Tokara Islands. Of the four new records, the southern limit of distributions was renewed for three species. Three exotic species, Pheidole fervens, Tetramorium bicarinatum, and Tapinoma melanocephalum were recognized, which seems relatively low given that ten exotic species have been altogether recorded from the Tokara Islands. The relationship between invasion by ants and the scale of human activity is discussed.

SummaryThe evidence of human activity in the Somerset Levels in the first millennium B.C. consists of wooden trackways laid across areas of developing raised bog, and joining small settlements on the higher, drier lands of the Poldens and the Wedmore ridge. The excavation of one of these tracks, of the sixth century B.C., is described. Stray finds of weapons and tools continue to be made by peat-cutters and by archaeologists; the most recent of these finds are a hazelwood peg or truncheon, and a sycamore tent peg, of the fourth or third century B.C. The relationship of the trackways and other finds to the marshside villages at Meare remains to be established.

AbstractThis article will show that the relationship between divine grace and human activity in the Anti-Climacus works should be understood as an inverted dialectic. Although Anti-Climacus communicates the strictness of Christianity and the importance of undertaking the Christian task, I will argue that the Anti-Climacus works are ultimately aimed at deepening the reader’s understanding of grace. By exploring Anti-Climacus’ accounts of human imagination and will in coming to faith and in the task of following Christ, it becomes clear that human activity ultimately reveals human beings’ limitations and their dependence on grace.

Abstract: The commentary presents an epistemological reflection about Dialogical Self theory. First, the theoretical issues of DS about the relationship between individuality, alterity and society are discussed, elaborating on the articles of this special issue. Then, it is presented the argument of psychologist's ontological fallacy, that is the attitude to moving from the study of processes to the study of psychological entities. Finally a development toward new research directions is proposed, focusing on the study of higher psychological functions and processes, taking into account complex symbolic products of human activity and developing psychological imagination.

A new species of the genus Piestus Gravenhorst is described from Peru, P. chullachaqui sp. nov. (Cuzco). Photographs and drawings of the major diagnostic characters are provided. A key to Piestus species is modified to include the new species. New records are provided for Piestus angularis Fauvel, Piestus bicornis (Olivier), Piestus fronticornis (Dalman), Piestus lacordairei Laporte, Piestus longipennis (Fauvel), Piestus mexicanus Laporte, Piestus minutus Erichson, Piestus pennicornis Fauvel, Piestus spinosus (Fabricius), Piestus sulcatus Gravenhorst, Piestus surrufus Caron et al. and Piestus validus Sharp. Cladistic analysis is made to know the relationship of the P. chullachaqui sp. nov. within Piestus.

Abstract The geographic distribution of Tillandsia aeranthos is updated with new records. Its southern limit is extended 200 kilometers in a zone previously studied by many botanists and naturalists, but also in poorly explored areas. For this reason, the possibility that the change in distribution is recent is postulated and discussed. The coincidence of this change with the southward shift in the isohyets and the decrease of winter frost frequency are highlighted as a possible cause of the advance to the south. In addition, two petal color variants of this species are first mentioned for Argentina. The new findings display that it is necessary to further explore some dry forests of eastern Buenos Aires and study the possible consequences of the climatic change in the biota of South America.

The establishment and spread of exotic species is a contemporary major concern. Alien species may become invasive in their new habitat, leading to both/either environmental and/or economic impacts. I briefly reviewed the literature in the last decade about the relationship of exotic species and native communities. I identified that professionals usually approach the subject in two main points of view: (1) researchers tend to point out the impacts of alien species on entire communities, evaluating if the relationship is positive, negative or neutral; (2) they focus on the eco-evolutionary processes involved in the introductions, the dynamics of invasion, and individual study cases. When evaluating the response of introductions to entire communities, evidence seems to be ambiguous and may support positive, negative or neutral relationship, especially depending on the scale approached. The unique eco-evolutionary pathways of each introduction may be a great shortcoming in the searching for generalities. On the other hand, advances have been made in understanding the dynamics of invasion on different lineages through a more selective/individualized approach. I suggest that the dynamics of invasion might be studied through a perspective in which different eco-evolutionary processes, levels of organization (from gene to entire communities), the history of the organism(s) and time are taken into account. Individual cases might be compared in attempt to understand how the relationship exotic and native works and in the search for generalities.

Computer simulation is a tool increasingly used by archaeologists to build theories about past human activity; however, simulation has had a limited role theorising about the relationship between past behaviours and the formation of observed patterning in the material record. This paper visits the argument for using simulation as a means of addressing the gap that exists between archaeological interpretations of past behaviours and their physical residues. It is argued that simulation is used for much the same reason that archaeologists use ethnographic or experimental studies, and that computational models can help to address some of the practical limitations of these approaches to record formation. A case study from arid Australia, examining the effects of episodic surface erosion on the visibility of the record, shows how simple, generative simulations, grounded in formational logic, can be used to compare different explanatory mechanisms and suggest tests of the archaeological record itself.

We present a checklist of 278 species of reef fishes recorded along the coastline of Santa Catarina state, the southernmost limit of distribution of tropical ichthyofauna on the coast of Brazil. Twelve new species records for this state are presented: Acanthurus coeruleus, Acanthurus monroviae, Apogon americanus, Cantherhines macrocerus, Chaetodon sedentarius, Chromis flavicauda, Clepticus brasiliensis, Decapterus punctatus, Gymnothorax vicinus, Herpetoichthys regius, Muraena retifera and Stegastes partitus. Stegastes partitus and H. regius are reported for the first time, respectively, from the Southwestern Atlantic and for the coastal part of this region, while Acanthurus monroviae is reported for the second time for the Southwestern Atlantic. We present habitat distribution, trophic structure and comment on biogeographic affinities of this transitional region, discussing both remarkable species presences and absences.

Minimalist Framework

As consultant-educators, the authors created the extreme architecture framework (XAF) in order to quickly grasp an understanding of an organisation’s architecture from different perspectives. The framework is presented as a matrix of system types and architectural perspectives that is described by a single uncluttered diagram. Elements within the framework are defined along with the content that can include architectural representations, planning, and governance information. A discussion follows to show the relationship of the framework to planning, development, and governance activities. The minimalist framework presents a consolidated view of both human activity and software systems and can also help to foster a shared understanding between IT groups and business areas. It has been designed to answer a manager’s questions: • Which elements of the enterprise do I need to be aware of and understand; and • Which elements am I responsible for and need to manage?
