Division of labour within cooperatively breeding groups

Within cooperative societies, group members share in caring for offspring. Although division of labour among group members has been relatively well studied in insects, less is known about vertebrates. Most studies of avian helping focus solely on the extent to which helpers provision the offspring, however, helpers can participate in everything from nest building to predator defence. Bad provisioners may, for example, not be as 'uncooperative' as they appear. if they are good defenders. Thus, the distribution of helping tasks between group members should have important implications for our interpretation of group dynamics. Here, we compare two distinct forms of helping behaviour in the cooperatively breeding noisy miner (Manorina melanocephala): chick provisioning and mobbing nest predators. We show that the way in which individual helpers invest in these two helping behaviours varies enormously across individuals and among social groups. Good provisioners often contributed relatively little to mobbing and vice versa. Indeed, (18%) of helpers only mobbed, 22% just provisioned, whereas 60% of helpers performed both forms of helping. Across nests, provisioning was significantly negatively correlated with mobbing effort. We suggest that small differences in the costs or benefits of different aspects of helping (due to differences in age, relatedness or social status) have a big impact on the division of labour within a group. Consequently, social groups can be made up from individuals who often specialise in one helping behaviour, and/or helpers who perform a number of behaviours to differing degrees. Division of labour within social groups will, therefore, have important consequences for the maintenance of cooperatively breeding in vertebrates.

AVALIAÇÃO DA PROPORÇÃO DENTAL DE BOLTON EM INDIVÍDUOS COM OCLUSÃO NORMAL NATURAL E MALOCLUSÕES DE CLASSE I E CLASSE II DIVISÃO 1 DE ANGLE.

Introdução: A análise de Bolton, análise que quantifica o tamanho dentário, é uma referência importante para profissionais que buscam finalizações ortodônticas adequadas. Objetivo: O objetivo deste trabalho é verificar se há discrepância entre os indivíduos com oclusão normal natural e maloclusões de Classe I e de Classe II divisão 1 de Angle pertencentes a amostra selecionada, em relação aos valores encontrados por Bolton, bem como verificar também se há dimorfismo sexual. Metodologia: 3 grupos contendo 35 pares e modelos em gesso cada, separados pelo tipo de oclusão, pertencentes ao acervo do programa de pós-graduação em Ortodontia da Universidade Metodista de São Paulo foram medidos com paquímetro digital em sua maior distância mésiodistal desde 1º molar direito a 1º molar esquerdo, dos arcos superiores e inferiores, com dentição permanente. Os valores foram tabulados e a proporção de Bolton foi aplicada. Resultados: Respectivamente para os grupos 1, 2 e 3, a proporção total encontrada foi de 90,36 (DP±1,70), 91,17 (DP±2,58) e 90,76 (DP±2,45), e a proporção anterior foi de 77,73 (DP±2,39), 78,01 (DP±2,66) e 77,30 (DP±2,65). Conclusão: não houve dimorfismo sexual nem diferença estatisticamente significante comparando os valores aos sugeridos por Bolton.

Bragg Grating fast Tunable Filter For Wavelength Division Multiplexing

A Bragg grating fast tunable filter prototype working over a linear tuning range of 45 nm with a maximum tuning speed of 21 nm/ms has been realized. The tunable filter system is based on two piezoelectric stack actuators moving a mechanical device thus compressing an apodized fiber Bragg grating. The filter allows both traction and compression and can work in transmission and in reflection. It is designed to work with a channel spacing of 100 GHz according to the ITU specifications for wavelength division multiplexing systems

10 Mb/s visible light transmission system using a polymer light-emitting diode with orthogonal frequency division multiplexing

We present a newly designed polymer light-emitting diode with a bandwidth of ∼350 kHz for high-speed visible light communications. Using this new polymer light-emitting diode as a transmitter, we have achieved a record transmission speed of 10 Mb/s for a polymer light-emitting diode-based optical communication system with an orthogonal frequency division multiplexing technique, matching the performance of single carrier formats using multitap equalization. For achieving such a high data-rate, a power pre-emphasis technique was adopted. © 2014 Optical Society of America.

Interpreting "D.I.Y." documents:severance, release, trusts, certainty, vesting and undue influence

Comments on the Chancery Division decision in Wallbank v Price on whether a home-made ("DIY") document signed by a wife and purporting to revoke her rights as a beneficial joint tenant in the matrimonial home, which was acquired under the right-to-buy scheme, should be set aside for duress or undue influence. Details the court's analysis of the principles supporting a successful claim of undue influence, the nature of the DIY document, its meaning and its effect. Considers possible reasons for the parties' use of the document.

Capacity of nonlinear fibre channels and eigenvalue division multiplexing for optical transmissions

The nonlinear Fourier transform, also known as eigenvalue communications, is a coding, transmission and signal processing technique that makes positive use of the nonlinear Kerr effect in fibre channels. I will discuss recent progress in this field. © 2015 OSA.
