Plagues of pests have always been a part of recorded history, but they hold special significance in the early modern period. 'Imperfect Creatures' is the first full-length study to investigate the shifting, unstable, but foundational status of “vermin” as creatures and category in the early modern literary and scientific imagination.

Objective-To estimate disease prevalence among dogs and cats in the United States and Australia and proportions of dogs and cats that receive therapeutic diets or dietary supplements. Design-Telephone survey. Sample Population-Dog and cat owners located in 5 geographic areas. Procedures-A telephone survey was administered to dog and cat owners. Results-Of 18,194 telephone calls that were made, 1,104 (6%) were to individuals who owned at least I dog or cat and agreed to participate. Information was collected for 635 dogs and 469 cats. Only 14 (1%) respondents indicated that their pet was unhealthy, but 176 (16%) indicated that their pets had 1 or more diseases. The most common diseases were musculoskeletal, dental, and gastrointestinal tract or hepatic disease. Many owners (n = 356) reported their pets were overweight or obese, but only 3 reported obesity as a health problem in their pets. Owners of 28 (2.5%) animals reported that they were feeding a therapeutic diet, with the most common being diets for animals with renal disease (n = 5), reduced-calorie diets (5), and reduced-fat diets (4). Owners of 107 of 1,076 (9.9%) animals reported administering dietary supplements to their pets. Multivitamins (n = 53 animals), chondroprotective agents (22), and fatty acids (13) were the most common dietary supplements used. Conclusions and Clinical Relevance-Results suggest that most dogs and cats reported by their owners to have a health problem were not being fed a therapeutic diet. In addition, the rate of dietary supplement use was lower than that reported for people.

Polycystic ovary syndrome affects 6  percent of women. Symptoms include hirsutism, acne, and infertility. This research explores the impact of polycystic ovary syndrome on women's lives using photovoice. Nine participants photographed objects related to their quality of life and made diary entries explaining each photograph. Three themes emerged from thematic analysis of the diaries: control (of symptoms and polycystic ovary syndrome controlling their lives), perception (of self, others, and their situation), and support (from relationships, health care systems, and education). These findings illuminate positive aspects of living with polycystic ovary syndrome and the role pets and social networking sites play in providing support for women with polycystic ovary syndrome.

Chimpanzees are native only to the jungles of equatorial Africa, but for the last hundred years, they have also lived in captivity in the United States, most commonly in biomedical research laboratories, but also at Air Force bases for experiments for the space program, at accredited and unaccredited zoos, at circuses, as performers in Hollywood and even in private homes and backyards as pets. But that has been gradually evolving over the last few decades, as more and more chimpanzees move to newly-established chimpanzee sanctuaries. That transition was already underway even before the announcement by the National Institutes of Health (NIH) last year that it will retire all of its remaining chimpanzees from labs to sanctuaries. By thoroughly examining the evolution of these sanctuaries leading up to that seminal decision, along with the many challenges they face, including money, medical care, conflicting philosophies on the treatment of animals and the pitfalls that have led other sanctuaries to the brink of ruin, we can take away a better understanding of why chimpanzee sanctuaries are needed and why caretakers of other animal species are now looking to the chimpanzee sanctuary movement as a model to show how animals can be cared for in retirement.

This paper presents the novel theory for performing multi-agent activity recognition without requiring large training corpora. The reduced need for data means that robust probabilistic recognition can be performed within domains where annotated datasets are traditionally unavailable. Complex human activities are composed from sequences of underlying primitive activities. We do not assume that the exact temporal ordering of primitives is necessary, so can represent complex activity using an unordered bag. Our three-tier architecture comprises low-level video tracking, event analysis and high-level inference. High-level inference is performed using a new, cascading extension of the Rao–Blackwellised Particle Filter. Simulated annealing is used to identify pairs of agents involved in multi-agent activity. We validate our framework using the benchmarked PETS 2006 video surveillance dataset and our own sequences, and achieve a mean recognition F-Score of 0.82. Our approach achieves a mean improvement of 17% over a Hidden Markov Model baseline.

[EN]In visual surveillance face detection can be an important cue for initializing tracking algorithms. Recent work in psychophics hints at the importance of the local context of a face for robust detection, such as head contours and torso. This paper describes a detector that actively utilizes the idea of local context. The promise is to gain robustness that goes beyond the capabilities of traditional face detection making it particularly interesting for surveillance. The performance of the proposed detector in terms of accuracy and speed is evaluated on data sets from PETS 2000 and PETS 2003 and compared to the object-centered approach. Particular attention is paid to the role of available image resolution.

O comércio de espécies selvagens tem crescido bastante ao longo das últimas décadas. Atualmente é considerado o quarto maior tráfico ilegal no mundo, logo seguido da transação de drogas, de armas e de humanos. Estima-se que o comércio de espécies selvagens pode ultrapassar os 12 milhões de euros por ano na UE. Abrange tanto as plantas como os animais vivos; mas, nestes últimos, incluem-se também os seus derivados, tais como sejam as peles, os ossos, alimento, entre outros. O uso das espécies selvagens é bastante vastos, as espécies são utilizadas para alimentação, uso medicinal, investigação científica, comércio de peles, alimentação e o mais comum é para animais de estimação. As espécies exóticas muitas vezes tornam-se espécies exóticas invasoras, começam a ser um perigo para a biodiversidade e para as espécies nativas. O processo de invasão apresenta-se por quatro fases: dispersão ou transporte, estabelecimento, naturalização e por fim dispersão geográfica e/ou invasão. Vários são os mecanismos para combater as espécies exóticas invasoras, sendo que o mecanismo mais radical a erradicação de espécimes. Em Lisboa, estão descritas três espécies exóticas invasoras: a tartaruga da Florida Trachemys scripta, a tartaruga de Nelson Pseudemys nelsoni e a tartaruga corcunda do Mississipi Graptemys pseudogeographica; ABSTRACT: The wildlife trade is growing fast over the last decades. It is now considered the fourth largest illegal trade in the world, followed by the drugs, weapons and humans. It is estimated that trade with species can exceed 12 million € per year in the EU. This trade comprises plants or live animals; but also is derivatives, such as skins, bones, food, and others. The use of wildlife is diverse, can be for food, medical, scientific research, trade of skins, but the most common is for pets. Alien species can become invasive alien species and so they become a threat to biodiversity and for native species. The process of invasion has four phases: dispersion or transport, establishment, naturalization and geographic dispersion and/or invasion. There are several mechanisms to combat such invasive alien species: the most radical mechanism is eradication of specimens. In Lisbon, are described three invasive alien species: the red-eared slider turtle Trachemys Florida, the Florida red-bellied turtle Pseudemys nelsoni and the false map turtle Graptemys psedogeographica.
