The Family Scolarship Program while public politics of intersectorial form developed by Social Development Department and Famine Combat having with partner the Education Department and Health Department inaugurate in the country a new integrity way of the public politics, reinforcing a precept of 2004 Social Protection National Politics (PNAS 2004) that places the social protection while allied to the social and human development. The research INCOME TRANSFER AND LOCAL DEVELOPMENT: the family scolarship program in Pedra Grande-RN municipally had as aim to avaluate the permanent Family Scolarship Program as a possible element in local development of Pedra Grande-RN municipally understood as capacity expansion and improvement of life quality from its users. For this means we elaborate specifically the families` socio-economical profile; we avaluate the program repercussion in these families` lives; we analyse in which proportion occurred the capacity expansion and improvement of life quality of the users. The methodologic process was constituted by: literarture review about Income Transfer, Social Vulnerability, Development and Public Politics Avaluation to the criation of a theoric picture analysis. The documental research joined to the Social Development Department and Famine Combat of Pedra Grande Municipally Hall to obtain of the aims, program goals, and the profile of users. And finally, carrying out the interviews with the managers and experts of the Municipally Program and focal groups with the users to avaluate the permanent of the Program starting by the points of view of those ones. It was verified that the program expand the capacity (food, consumer goods and services, bank services access and wages) and improvement in life quality of the users. Nevertheless, there are deficiencies in coming with conditionality and from the use of resources the by families users

The Feira da Pedra is an extension of the open fair of São Bento in the State of Paraiba. It is a system of trade in textile goods produced by textile industry in manufacturing of hammocks and derivatives of this industry, present in some cities in the state of Paraiba and Rio Grande do Norte, as a survival strategy, inserted in the list of tertiary and retail of the urban economics of this city. It is thereby aimed to discuss about the urban economics, reflecting on the open fair system from the two circuits of urban economy, mainly in the context of the dynamics of the current period of geographic space, the technical-scientific-informational period, as the specific empirical object, the Feira da Pedra of São Bento (PB). For this, this research was carried out in two stages of operation: a) surveys of secondary data and b) primary data collection which were reported an operational triad: I) literature; II) documentary research, and III) research of field. The presence of the Feira da Pedra in São Bento has shown us one of the most important characteristics of this city, in order to present major economic, social and cultural benefits to the local population, and contribute to (re) production of sertanejo space, making lower part of the circuit of its urban economy. This activity has entailed several dynamics for urban space in this city, mainly because of attracting large numbers of people, carrying typical actions of its relationship with the urban space are são-bentense and built environment. Thus, its importance is not only a local and regional phenomenon, but also a cultural reference of a place in the geographical area of many paraibanos and norte-rio-grandenses subjects, as the case of this activity has brought to its weekly routine, this product resulting from the textile working of this area of Sertão Paraibano and Seridó Potiguar

The Conservation Units, specially the National and State parks are among the major destinations for adventure tourism and ecotourism, so that the National System of Unit Conservation (Sistema Nacional de Unidades de Conservação) SNUC (Law 9.985/2000) covers the practice of touristic activities, specially the ecotourism in these territorial unities. Despite these are areas for environmental conservation, practice of environmental education, scientific research and contemplation of the nature in its primary or in a similar condition, the practice of touristic activity does not often meet these aims. The main aim of this research was to evaluate the touristic activities and the actions of territorial management in the State Park of Pedra da Boca (PEPB), situated in the city of Araruna/PB. According to the results, the PEPB has in its territorial area a porphyritic granite rock set, whose geological and geomorphologic settings are unique and have scenic value. It is also home of flora and fauna endemic species and representative of the savanna biome. The data and information achieved show that the Park has a remarkable potential for tourism, especially ecotourism, however, there is a need for development of territorial management actions, in order to subsidize the use of spatial tourism site

Este trabalho teve como objetivo avaliar a capacidade de colonização do Brevipalpus phoenicis (Geijskes) em espécies de cercas-vivas, quebra-ventos e plantas invasoras mais freqüentes em pomares cítricos. O ensaio foi conduzido em laboratório e casa-de-vegetação, utilizando-se 11 espécies vegetais (tratamentos): Hibiscus sp., Malvaviscus mollis, Grevillea robusta, Mimosa caesalpiniaefolia, Bixa orellana, Euphorbia splendens, Bidens pilosa, Commelina benghalensis, Sida cordifolia e Ageratum conyzoides e Citrus sinensis. Adotou-se o delineamento estatístico de blocos casualizados, com cinco repetições. Para cada unidade experimental, constituída de uma planta envasada, foram transferidas 100 fêmeas de B. phoenicis provenientes de uma criação estoque. Decorridos 45 dias após a transferência dos ácaros para as plantas invasoras e 60 dias para as cercas-vivas e os quebra-ventos, estas tiveram suas folhas destacadas e seus ramos repicados para avaliação dos totais de estágios de desenvolvimento. Os dados relativos às contagens foram transformados em ln(x+5) e analisados pelo teste F. As médias foram comparadas pelo teste de Tukey (P < 0,05). As cercas-vivas e quebra-ventos mais favoráveis ao ácaro, em ordem decrescente, foram: M. mollis (6.342 ácaros), Hibiscus sp. (2.546), B. orellana (2.097), G. robusta (1.485) e M. caesalpiniaefolia (776). Nenhum ácaro foi encontrado em E. splendens. Com relação às plantas invasoras, foram: B. pilosa (2.238), C. benghalensis (920), S. cordifolia (738) e A. conyzoides (684). em C. sinensis foram contados 3.116 ácaros. Com exceção de E. splendens, todas as plantas mostraram-se favoráveis ao crescimento populacional de B. phoenicis. A presença destes nos pomares cítricos pode representar uma ameaça à cultura.

Com o objetivo de estudar alguns aspectos relacionados à dormência das sementes de trapoeraba (Commelina benghalensis L.), dois experimentos foram conduzidos em condições de laboratório. No primeiro experimento, realizado em 1989, utilizaram-se sementes aéreas e subterrâneas oriundas de Paranavaí-PR e apenas sementes aéreas oriundas de Jaboticabal-SP, todas recém-colhidas, nas modalidades de grandes e pequenas (separadas de acordo com seu peso). Os tratamentos de quebra de dormência foram. escarificação mecânica com lixa; escarificação química com ácido sulfúrico; choque térmico úmido; choque térmico seco, além da testemunha. No segundo experimento, realizado em 1990, utilizaram-se sementes do mesmo lote do experimento anterior, após um ano de armazenamento em câmara a 10o C, sem qualquer tratamento de semente, visando verificar a germinação das sementes. Os resultados indicaram que: 1) o ácido sulfúrico foi o tratamento que proporcionou as maiores porcentagens de germinação (P.G.) e os maiores índices de velocidade de germinação (I.V.G.) em todos os tipos de sementes estudadas; 2) a P.G. e o I.V.G. das sementes recém-colhidas aumentam após um ano de armazenamento; 3) as sementes grandes apresentam maior P.G. e maior I.V.G. que as sementes pequenas; 4) as sementes colhidas em Paranavaí, apresentaram uma tendência de maior P.G. e maior I.V.G. que as colhidas em Jaboticabal.

Forest species with hard seeds often pose considerable problems to nursery managers because their hard and impermeable seed coats hinder and delay germination. Therefore, this work aimed to determine the most efficient, practical and low cost methodology to overcome dormancy in Sesbania virgata (Cav.) Pers. Seed, a specie with potential for recovery of degraded areas. The seeds were submitted to chemical scarification by immersion in sulfuric acid during a period of 5, 10, 20 and 30 minutes, mechanical scarification and heat treatment. After the scarification the seeds were submitted to germ test in germination chambers at 25oC and photoperiod of 14 h. Treatment with mechanical scarification showed the highest germination percentage (98%), followed by chemical scarification for 30 minutes (57%). The heat treatment in spite of obtaining a higher germination percentage than the controls had abnormal development of seedlings and is not therefore recommended for seeds of S. virgata. From the parameters utilized in this study, we recommend the use of the mechanical scarification to overcome dormancy of S. virgata seeds.
