President William Howard Taft and First Lady Nellie Taft at South Bass Island

This picture shows President William Howard Taft and First Lady Helen Herron Taft readying to lay the cornerstone of Perry's Victory and International Peace Memorial on South Bass Island in August 1912. The monument was built between 1912 and 1915 to commemorate Commodore Oliver Hazard Perry's victory on Lake Erie over the British fleet in September 1813. It also represented the lasting peace between the U.S., Canada, and England.

The Effectiveness of Outdoor Education on Environmental Learning, Appreciation, and Activism

The main objective of this research was to determine the effectiveness of outdoor education on student knowledge retention, appreciation for nature, and environmental activism in a college level course on south Florida ecology. Six class sections were given quizzes on four course topics either post-lecture or post-field trip. Students were also given pre-course and post-course opinion surveys. Although mean quiz scores for the post-field trip were higher than for the post-lecture, statistical analysis determined that there was no significant difference in quiz scores for location taken (post-lecture or post-field trip). Survey results show a correlation between knowledge of environmental issues and environmental activism. Even though student survey responses point to outdoor education and field trips being the most effective method of learning and influential on appreciation for nature, the quiz scores do not reflect such.

Subjetividades políticas desde la representación : fotografía documental del campesinado en Colombia (1965-1975)

Esta investigación explora arqueológicamente el saber constituido sobre el campesinado en Colombia, en el período de 1965-1975, tomando como material empírico principal un archivo fotográfico documental que relacionaremos con hemerografía y las reconstrucciones socio-históricas de la década. Nuestro propósito es relacionar el archivo, sus condiciones, su porvenir, medios y definiciones con la constitución de subjetividades políticas. Las subjetividades son entendidas aquí en tanto procesos que al referir universos simbólicos socialmente compartidos, dotan al sujeto de un lenguaje cultural que a continuación internaliza, y adquiere así una singularidad que lo caracteriza y finalmente lo representa como “ser colectivo”. Descifraremos, a través de lo visible y lo oculto de las representaciones fotográficas, los enunciados posibles y las aproximaciones desde la sociología. Veremos como los discursos, por demás contradictorios, fungen a manera de proyectos de homogeneización de la cultura campesina efectuándose en la esfera de la heterogeneidad: campesinos marcados por diferencias entre sí, multiplicidad de subjetividades implicadas políticamente en los procesos inscritos dentro de la reforma agraria.

Neotypification of Hybanthus longistylus (Violaceae)

Recent studies on South American Hybanthus Jacq. s.l. (Violaceae) revealed the need to select a neotype for the name H. longistylus Schulze-Menz, the holotype of which was destroyed in Berlin during World War II.

Entangled States and Collective Nonclassical Effects in Two-Atom Systems

We propose a review of recent developments on entanglement and nonclassical effects in collective two-atom systems and present a uniform physical picture of the many predicted phenomena. The collective effects have brought into sharp focus some of the most basic features of quantum theory, such as nonclassical states of light and entangled states of multiatom systems. The entangled states are linear superpositions of the internal states of the system which cannot be separated into product states of the individual atoms. This property is recognized as entirely quantum-mechanical effect and have played a crucial role in many discussions of the nature of quantum measurements and, in particular, in the developments of quantum communications. Much of the fundamental interest in entangled states is connected with its practical application ranging from quantum computation, information processing, cryptography, and interferometry to atomic spectroscopy.

Avian Infectious Bronchitis Virus in Brazil: A Highly Complex Virus Meets a Highly Susceptible Host Population

Infectious bronchitis (IB) is a highly aggressive disease for poultry in terms of symptoms and economic losses, and the control of this disease is difficult if flocks are not protected against type-specific challenges by the Avian infectious bronchitis virus (IBV). This article summarizes data presented by the author at the Workshop on Infectious Bronchitis 2009 on IB and IBV, including future developments on the field.

A casa de Porto Seguro : estudo da morfologia da casa portuguesa no Brasil

O estudo da morfologia das casas da rua Dr. Antônio Ricaldi na Cidade Alta de Porto Seguro no estado da Bahia tem como objetivo esclarecer os limites da influência da arquitetura portuguesa na construção das casas do sítio histórico referido tombado pelo IPHAN desde 1973. Foi realizado um estudo comparativo da tipologia das casas do mesmo conjunto arquitetônico e através da referência teórica da história da arquitetura portuguesa e da evolução urbana nos primeiros núcleos populacionais no Brasil é apresentado a aproximação tipológica portuguesa mais semelhante as casas do conjunto estudado em Porto Seguro. A pesquisa de campo foi realizada na Cidade Alta de Porto Seguro de 2012 à 2014. O recorte escolhido para o estudo foram 25 casas da rua Dr. Antônio Ricaldi, com ênfase na casa de Edson Ramalho Jr número 65; por sua relevância na conservação da tipologia como um exemplo mais semelhante a uma casa vernácula1 de porta e janela análoga às primitivas construções desse sítio. Esta casa tem um destaque especial por sua localização privilegiada dentro do sítio e como um ponto de referência da história da arquitetura portuguesa no Brasil. O uso da casa como museu: Casa Histórica aconteceu de 1996 à 2004 como um modelo capaz de elencar projetos culturais e educativos para a Cidade Alta, visando o uso, conservação, difusão e sustentabilidade do patrimônio histórico e cultural. A documentação levantada com a pesquisa é relevante para o estímulo da arquitetura vernácula e uma referência à memória da arquitetura portuguesa no Brasil. Fomentando novos estudos e empreendimentos sobre o tema, para um sítio histórico pouco estudado, em uma região de grande visitação turística no Brasil mas, sem projetos que visem a devida conservação, apresentação e uso desse sítio de forma sustentável

Human-Human Collaboration in Virtual Teams

Extended and networked enterprises distribute the design of products, planning of the production process, and manufacturing regionally if not globally. Employees are therefore confronted with collaborative work over remote sites. A cost effective collaboration depends highly on the organization maintaining a common understanding for this kind of work and a suitable support with information and communication technology. The usual face to face work is going to be replaced at least partly if not totally by computer mediated collaboration. Creating and maintaining virtual teams is a challenge to work conditions as well as technology. New developments on cost-effective connections are providing not only vision and auditory perception but also haptic perception. Research results for improving remote collaboration are presented. Individual, social and cultural aspects are considered as new requirements on the employees of networked and extended enterprises.

La biochronologie des Mammifères néogènes d'Europe. L'échelle MN, son application à la succession des faunes du Portugal

Similarly to other organisms, Vertebrates changed during the Cenozoic Era. Mammals are the only ones to change quickly; their well mineralised bones and teeth are often fossilised. They are highly diverse and even isolated teeth can be identified. They are thus a good tool for establishing a biochronological framewoork. Among Mammals, Rodents with a short lifetime evolve more quickly than the large Mammals. In Europe, the first elaborated zonation was investigated by the Regional Committee on Neogene Stratigraphy and issued as the MN Zonation (Mammals Neogene) by Mein, 1976. During the following years, progress in knowledge lead to new charts. The latest one resulted from collective work (de Bruijn et al., 1992). Bîochronology gives relative data; if we desire to have numerical age estimates, we must correlate these results with radiometrie data, marine biostratigraphîcal units or the Geomagnetic Polarity Time Scale. For Europe, these results are summarised by Steininger et al. (1989-1996) and Steininger (1999). After some recents developments on MN Zonation, here is discussed the succession of Neogene small mammals Portuguese localities. Fortunately these localities are in majority inbedded in marine context. Their assigment to MN Zones is proposed and correlations with the spanish Aragonian Scale (Daams el al., 1999) are also suggested. In fact, some differences appear between Portugal and Aragonian assemblages, probably for ecological reasons. Therefore, the MN zonation is always useful for short and long distance biochronological correlations.

How to feel “in love" with math: a MOOC experience

In the past few years we have witnessed astonishing developments on distance learning tools, in particular on Open Educational Resources (OER) such as Massive Open Online Courses (MOOC). In this paper we present the “Mathematics without STRESS”, a MOOC Project, which has been a collaborative volunteer effort that brought together professors, from four schools of the Polytechnic Institute of Oporto (IPP), in Portugal. Some concepts directly associated with MOOC and their quickly growing popularity are complemented with a discussion of some particular MOOC characterizations. The design process of this project is revealed by focusing on the MOOC structure we used, as well as on the several types of course materials that were produced. At last, we undertake a short discussion about some of the problems, achievements and challenges met throughout this project development, giving a special attention to the motivational aim of this work - hoping to contribute to a change in the way of teaching and learning Mathematics is seen and practiced nowadays.
