Elaborate secondary sexual traits, such as the ornamental plumage of birds, may be favored by female choice because they serve as honest indicators of male quality. Elaborate traits are thought to be honest signals because they are expensive to produce and increase predation risk. Here we investigate another potential cost of elaborate traits, i.e., the time and energy required to maintain them...

The authors present an analytical model of a irst-price sealed-bid cattle auction in which a spot and coordinated markets are interconnected. The model reveals that the conventional wisdom that market coordination negatively affects the bid price in the spot market is an oversimpli ication. The relationships between key market variables impact bids and bid shading in complex ways. While captive...

This article examines archaeological studies of the cultural heritage and social dynamics of African descendant populations in the United States and Canada from AD 1400 through 1865. European colonial enterprises expanded in Africa and the Americas during that time span, effecting an accompanying movement of free and captive Africans into North America. Archaeological investigations of early Af...

Reintroduction projects may fail because captive-reared animals do not possess the behavioural skills required for survival in the wild. Rearing captive-bred animals in semi-natural enclosures prior to release has been used to improve the survival of reintroduced endangered species, but it is unclear how rearing environment influences the development of behaviour. This study examined the effect...

The documentary film Blackfish (2013; www.blackfishmovie.com) follows Tilikum, a captive SeaWorld prisoner-orca responsible for the death of trainer Dawn Brancheau and two others. The film has had a profound effect on public perceptions of orca captivity creating the “Blackfish Effect.” Our critical analysis of the film engages Plec’s (2013) internatural communication categories of complicity, ...

This study, using the method of direct collection feces, investigated captive giant pandas daily intakes and apparent digestibility coefficients of diet dominantly comprised of Phyllostachys vivax bamboo shoots. The results showed that the captive giant pandas daily ingested ~2818 g (dry mass) of bamboo shoots (corresponding to ~42 kg of fresh bamboo shoots with shells). Based on this daily int...

Purpose – The motivation for this research is to contribute towards development of a management framework for offshore Business Process Outsourcing (BPO). Design/methodology/approach This paper utilises longitudinal case studies to identify success factors in managing offshore Business Process Outsourcing (BPO) via the captive model (i.e. wholly-owned subsidiary). Findings – Success in offshore...

This document describes a DHCP option (and a Router Advertisement (RA) extension) to inform clients that they are behind some sort of captive-portal device and that they will need to authenticate to get Internet access. It is not a full solution to address all of the issues that clients may have with captive portals; it is designed to be used in larger solutions. The method of authenticating to...

This paper represents a review of different tagging activities carried out on bluefin tuna (Thunnus thynnus) in the eastern Atlantic and Mediterranean Sea. Except in Croatia where tagging has been done on captive specimens, all other tagging campaigns, performed within framework of joint European Tuna Tagging Programme, have been done on bluefin tuna released in the open sea. Besides the taggin...
