Black American perceptions of social workers

This study examines Black Americans\u27 perceptions of social workers and of the role of the Black church and extended family in assisting individuals in the Black community. The study employed a survey design with self-administered questionnaires. Sixty respondents participated in the study and the study was conducted at two Black churches in the San Bernardino County

Documenting Abilities And Achievements: The Use Of Professional Portfolios For Accounting Students And Young Accounting Professionals

Requiring students to develop portfolios as part of the educational process is a common technique that is utilized by educators who teach various subjects from kindergarten through graduate school. Collecting course assignments and projects into a portfolio helps students see the development of their skills as they progress through school toward graduation. Portfolio development is prevalent in certain majors – such as art and education – as well as in certain professions - such as marketing and communication.  While portfolios are not typically utilized in the profession of Accounting, there are many benefits to requiring that undergraduate Accounting majors track their educational progress with a portfolio.  Doing so will allow Accounting majors to understand their learning more – make it less cerebral and more recognizable.  Portfolios will also assist the Accounting major to achieve entry-level professional employment

Forgeries and public collections

Large public collections, however prestigious, inevitably have some forgeries in their storerooms (and occasionally on display) and, although this aspect may seem reprehensible in a publicly funded collection, it is almost inevitable, given the means by which collections are built up by museums. All collectors are vulnerable to forgers who customise their products to tempt the buyer with something that will fill an important gap in their collection, and museums are just as likely to fall for this as private collectors. Forgeries may also enter museum collections as gifts. Museums not infrequently receive bequests from generous patrons, sometimes comprising large numbers of objects, and amongst them a forgery may be included, unrecognised, and may remain unquestioned for many years before coming to the attention of a curator or visiting scholar. This paper presents some case studies of objects in the British Museum for which scientific analysis has demonstrated that either the materials or the technology used in their making are not compatible with their supposed date of manufacture.Les collections publiques, bien que prestigieuses, contiennent inévitablement quelques objets modernes dont certains sont exposés. Bien que cela puisse sembler critiquable dans le cas de collections publiques, ceci est inévitable au vu de la façon dont les collections des musées se sont formées au cours des décennies. Tout collectionneur d’art se trouve vulnérable face aux faussaires qui adaptent leurs « produits » pour correspondre à l’attente des acquéreurs ; les collectionneurs privés cherchant à combler une lacune importante dans leurs collections, tout comme les musées. Les faux ou les copies modernes, peuvent également être entrés dans les collections publiques par voie de donation. Il est en effet courant que les musées publics reçoivent des donations de personnalités importantes, collections qui sont parfois conséquentes et possédent un ou plusieurs faux. L’authenticité de ces objets ne sera pas questionnée, parfois pendant plusieurs années, jusqu’au moment où, par chance, dans le cadre d’un projet de recherche spécifique, ils soient proprement analysés par des méthodes scientifiques. Cet article présente quelques cas d’études d’objets appartenant à la collection du British Museum, pour lesquels l’étude scientifique a pu prouver que les techniques de fabrications utilisées ne pouvaient pas être compatibles avec leurs dates de fabrication supposées

Metallurgical case studies from the British Museum's collections of pre-hispanic gold

El Museo Británico ha comenzado recientemente un programa de estudio científico y tecnológico de su colección de objetos de orfebrería prehispánica. Para este programa se usa microscopía óptica y electrónica de barrido, análisis radiográficos y de fluorescencia de rayos X. En este artículo se presentan estudios de caso interesantes que muestran un rango de prácticas de orfebrería que incluye dorado, uso de matrices de piedra para la elaboración de moldes e identificación de falsificacione

Pattern formation on the surface of cationic-anionic cylindrical aggregates

Charged pattern formation on the surfaces of self--assembled cylindrical micelles formed from oppositely charged heterogeneous molecules such as cationic and anionic peptide amphiphiles is investigated. The net incompatibility $\chi$ among different components results in the formation of segregated domains, whose growth is inhibited by electrostatics. The transition to striped phases proceeds through an intermediate structure governed by fluctuations, followed by states with various lamellar orientations, which depend on cylinder radius $R_c$ and $\chi$. We analyze the specific heat, susceptibility $S(q^*)$, domain size $\Lambda=2\pi/q^*$ and morphology as a function of $R_c$ and $\chi$.Comment: Sent to PRL 11Jan05 Transferred from PRL to PRE 10Jun0

O ENSINO DOS ESPORTES COLETIVOS NO ENSINO FUNDAMENTAL: FUTSAL E VOLEIBOL

Esta pesquisa tem como objetivo verificar o processo de ensino dos esportes coletivos – futsal e voleibol, utilizando como metodologia de ensino a abordagem crítico-emancipatória. Esta se apresenta como uma pesquisa qualitativa do tipo pesquisa-ação, utilizando como instrumentos de coleta de dados os relatórios das intervenções, estes sendo realizados durante as aulas da disciplina Estágio Supervisionado: Pesquisa da Prática Pedagógica do sexto período do curso de Licenciatura em Educação Física. Participaram do estudo aproximadamente 41 escolares com idade entre 12 a 14 anos. Os alunos cursavam a sétima série do Ensino Fundamental no período matutino, do Colégio de Aplicação da UNIVALI (CAU), localizado em Itajaí / SC – Brasil. A razão que levou o pesquisador a realizar o estudo surgiu de reflexões feitas sobre a prática dos esportes futsal e voleibol durante a época de discente e observações feitas em meio acadêmico, a partir de estudos realizados na disciplina Pedagogia do Esporte. A análise dos resultados se delimita as reflexões das intervenções, ou seja, da prática pedagógica a partir dos dados coletados. Por fim, se recomenda a realização de outras pesquisas relacionadas, que possam dispor de mais tempo para estudos principalmente empíricos e desta forma, que possam abranger mais modalidades de esportes coletivos, tratando da pedagogia no ensino dos esportes

Depletion gilding, innovation and life-histories: The changing colours of Nahuange metalwork

The technique of depletion gilding is well evidenced in pre-Columbian Andean gold work. Artefacts from the Nahuange period in Colombia (c. AD 100-1000) were subject to metallographic, chemical and microscopic analyses to provide regional comparative data on metalworking traditions. Results suggest that depletion gilding may have been an accidental discovery and, contrary to widespread assumptions, not always a desirable feature. This research illustrates how technological innovation may not always be immediately adopted, and considers how the life-history of gold artefacts may affect their appearance and microstructure. It also offers directions for future studies of depletion gilding elsewhere
