Research on the development of citizenship has been reinvigorated by considering adolescents as participants actively engaged in, and interacting with, family, peers, teachers, and the media. This contrasts with earlier top-down transmission models that saw adolescents as passive recipients of information from parents and teachers. Active citizenship is now seen as a largely indirect result of ...

INTRODUCTION The 2004 Children Act in the UK saw the introduction of integrated working in children's services. A raft of change followed with processes designed to make joint working easier, and models and theories to support the development of integrated work.

We report for the first time overt rehearsal data in immediate serial recall (ISR) undertaken at three presentation rates (1, 2.5, and 5 sec/word). Two groups of participants saw lists of six words for ISR and were required either to engage in overt rehearsal or to remain silent after reading aloud the word list during its presentation. Typical ISR serial position effects were obtained for both...

Possible generation structure is investigated. We considere alternative possibility of combination of leptons and quarks to compose each generation, where the combination of (ντ , τ) and (u, d) compose a generation. Our model exhibits the hierarcy structure after sea-saw mechanism provived that possible existence of realistic right-handed neutrinos are taken into account. Then, in the GUTs mode...

of Malawi Not long after the explorer, medical missionary and anti-slavery campaigner Dr David Livingstone explored Lake Nyasa, now Lake Malawi, a wave of evangelising zeal saw the establishment of religious communities along the lake shore. One of those who went forth was an Anglican priest, Chauncy Maples. After 19 years, he was recalled to England to be appointed the Bishop of Nyasaland. It ...

In speech production, high-frequency words are more likely than low-frequency words to be phonologically reduced. We tested in an eye-tracking experiment whether listeners can make use of this correlation between lexical frequency and phonological realization of words. Participants heard prefixed verbs in which the prefix was either fully produced or reduced. Simultaneously, they saw a high-fre...

Thus the systems studied by CCGS do seem to be examSandslide or avalanche models were introduced in the work of Bak, Tang, and Wiesenfeld [1]. They looked at the process of adding grains of sand arbitrarily slowly to a model sandpile, and studied the spectrum of avalanches produced by the individual addition events. They suggested that the pile would adjust its slope to a critical value in whic...

Professional sociology in the U.S. began as a field area within economics, but gradually emerged as a separate discipline. Using new data on joint meetings and the separation of departments, I track interdisciplinary relations through three phases: sponsorship (1890-1905), collaboration (1905-1940), and disengagement (post-1940). In the early years, sociology was mostly a branch of economics de...

The autumn of 2014 saw public debate about the appropriate threshold for abortion and gestational age. Gestational age can be determined in a number of ways and ultrasound examination represents an important contribution. In Norway, two methods are in use: the Terminhjulet obstetric wheel, developed in Bergen (the Bergen method) by a group that includes some of the authors of this article, and ...
