Intersections of Gender, Books, and Power : Converging Interests in Narratives by/on Women of East Timor

Clara SARMENTO Asian Center for Women's Studies : Ewha Womans Uni 2014 Asian Journal of Women's Studies(AJWS) Vol.20 No.4

This essay discusses some political and theoretical texts on gender in Southeast Asia in general, and in East Timor in particular, with a view to examine values related to traditional female roles, as well as the strategies used to recognize women in political and social fields that are conventionally dominated by males. In the post-colonial space of East Timor, the intersections of past and present, of the global and the local, of war and peace, define the guidelines to explore the negotiation and evolution of gender concepts. Listening actively to the narratives of women from Southeast Asian transitional territories like East Timor, requires translation, equivalence, dialogue and negotiation resources, in order to find points of convergence and divergence with dominant knowledge and thus build and implement concrete and specific strategies, while exercising the hermeneutics of suspicion on the alleged universality of western thought. Este artigo discute alguns textos políticos e teóricos sobre condição de género no Sudeste Asiático em geral, e em Timor Leste, em particular, tentando analisar os valores relacionados com os papéis femininos tradicionais, bem como as estratégias utilizadas para reconhecer as mulheres em campos políticos e sociais que são convencionalmente caracterizados pelo domínio masculino. No espaço pós-colonial de Timor Leste, as intersecções de passado e presente, global e local, guerra e paz, definem as directrizes utilizadas para explorar a negociação e a evolução dos conceitos de género. Escutar activamente as narrativas de mulheres de territórios de transição do Sudeste Asiático, como Timor Leste, exige capacidades de tradução, equivalência, diálogo e negociação, a fim de encontrar pontos de convergência e de divergência com o conhecimento dominante e, assim, construir e implementar estratégias concretas e específicas, ao mesmo tempo que se exerce a hermenêutica da suspeita sobre a alegada universalidade do pensamento ocidental.

Z-R relationships were developed for the Eastern Coast of Northeastern Brazil (NEB) using rainfall raindrop size distribution (RSD)data collected with a disdrometer RD-69 in the Campus of the Universidade Federal de Alagoas (UFAL: The Federal University of Alagoas) in Maceió in 2001. The RSD was stratified by rainfall rate classes. It is found that the RSD are clearly dependent on the parameters of the analytical distribution functions are, and show a marked monthly variability. The parameters of the frequency distributions are dependent on the rain rate (R). The forms of RSDs are similar to previous studies but the amount of droplets is not in each one very strongly. This may be possible due to the short period of data collection or to the intraseasonal rainfall variability. The general relationship for the Eastern Coast of NEB was found to be Z = 176.5 R1.29, with correlation coefficient equal to 0.83. This equation is in accordance with the ones for stratiform rain reported in the literature. We found that the convective rain observed is produced by convective cells imbedded into stratiform cloud layers. However, when separating stratiform and convective rainfall we found that the linear coefficient of the Z-R relation is significantly smaller for convective rainfall than for stratiform one (65 and 167 respectively), but the exponential coefficient is higher for convective than for stratiform (1.69 and 1.26 respectively).

A precise knowledge of the ^(236)U neutron-induced fission cross-section is required for the development of accelerator-driven systems and reactors based on the Th-U cycle. The evaluated data presently stored in the nuclear data libraries rely on outdated experimental measurements and show large discrepancies in the energy region between 1 keV and 100 keV. More recent measurements made at LANSCE and GELINA yielded results which are in disagreement with the literature for the resonance region and below 10 eV. In order to improve the present knowledge of the ^(236)U(n, f) cross-section, a new measurement was performed at the neutron Time-Of-Flight facility n_TOF at CERN. A Fast Ionization Chamber was used, in which four samples of ^(236)U and two of ^(235)U were mounted. The ^(236)U(n,f) cross-section was determined relative to the standard ^(235)U(n, f) reaction. The contribution from the ^(235)U contamination in the samples was subtracted, together with the alpha-particle background. Finally, the data were corrected for dead-time and detection efficiency. The n_TOF results on the ^(236)U(n, f) cross-section are reported in the neutron energy region from 200 meV to 2 MeV. The present high-resolution data point to several shortcomings in the current evaluated databases in the sub-threshold region. High accuracy cross-sections, important for applications to fast nuclear reactors as well as for fundamental Nuclear Physics, are also reported here.

Agricultural production in developing countries plays an important role in ensuring food and nutrition security as well as in reducing poverty. Therefore the improvement and increase in the level of adoption of agricultural technologies, essentially among smallholder farmers, seems to be a key to enhance production and productivity in developing countries. Certified Seed remains one of the most important inputs in agricultural production and directly influencing agricultural productivity, and maximizing other inputs. The main objective of the current study was to assess the determinants factors of adoption of certified rice seed by farmers in Zambezia province, Mozambique. About 300 farmers in 3 districts were target as respondents in questionnaires to collect the primary data. In this study the dependent variable is binary (adopter and non-adopter) and dependent variables by using selected socio-economic variables. The result show that approximately 12% of respondents use Certified Seed, and concluded that the variables such as level of education, access to credit, availability and access to agro-dealers, the source of obtaining seed, the production system, and the access of assistance by extension services are statistically significant, which mean they are more likely have a chance to influence the adoption of Certified Rice Seed in Zambézia province.

Conservation presence, not socioeconomics, leads to differences in pastoralist perceived threats to argali

wesley sarmento,Richard P. Reading 국립중앙과학관 2016 Journal of Asia-Pacific Biodiversity Vol.9 No.3

Community-based conservation approaches that keep people on landscapes increasingly complement preservationist models of reserves without people. Evaluations of community conservation have shown that economic incentives and socioeconomics primarily drive people’s attitudes and perceptions. Work at Mongolia’s Ikh Nart Nature Reserve demonstrates how to achieve successful conservation by integrating local people into the overall program. Using a short questionnaire, we interviewed pastoralist families across two soums (similar to a U.S. county) in Ikh Nart. We examined (1) pastoralists’ perceived threats to argali sheep (Ovis ammon), (2) socioeconomic differences among pastoralists, and (3) differences between pastoralists from different soums. We found that 15 years of conservation activities—education, research, and modest ecotourism—that occurred in the northern soum led to influences on people’s perceptions toward argali conservation. Compared with pastoralists from southern Ikh Nart, pastoralists from the northern part of the reserve more likely knew that argali are protected and understood primary threats to the species. Socioeconomic factors, such as age, sex, and wealth, did not significantly influence responses. The negligible economic incentives in Ikh Nart did not lead to response differences. Our results demonstrate that conservation can influence people across socioeconomic classes without providing large economic incentives.

Z-R Relationships for a Weather Radar in the Eastern Coast of Northeastern Brazil

Tenorio Ricardo Sarmento,Kwon Byung-Hyuk,Silva Moraes Marcia Cristina da The Korea Institute of Information and Commucation 2006 Journal of information and communication convergen Vol.4 No.1

A disdrometer has been used to determine Z-R relationships for the weather radar, which is unique coastal radar operating regularly in western tropical south Atlantic. Rainfall rates were divided into the stratiform rain and the convective rain on the basis of $10\;mm\;h^{-1}$. The Z-R relationship for the stratiform class was similar to the general one since the convective clouds did not developed and two classes of the rain rate were mixed.

Raindrop Size Distribution Over Northeastern Coast of Brazil

Tenorio Ricardo Sarmento,Kwon Byung-Hyuk,Silva Moraes Marcia Cristina da The Korea Institute of Information and Commucation 2006 Journal of information and communication convergen Vol.4 No.1

Precipitation measurement with ground-based radar needs an information of the raindrop size distribution (RSD) characteristics. A 10-month dataset was collected in tropical Atlantic coastal zone of northeastern Brazil where the weather radar was installed. The number of drop was mainly recorded in 300 - 500 drop $mm^{-3}$, of which the maximum was registered around 1.1 mm drop diameter.

리오그랑디주에서 바이아주 남부까지 약 300 km에 이르는 길고 좁은 브라질 북동부 지역에서는 남동무역풍의 교란, 전선의 침투, 해륙풍 순환 그리고 지형과 수증기 플럭스에 기인하는 국지 대류와 같은 다양한 강수 시스템이 나타난다. 연간 총강수량은 내륙에서는 600 mm, 해안지역에서는 3000 mm의 분포를 보이고 있다. 지역 기후 평균에 5-12배의 강수량이 2004년 1월에 알라고아스주 여러 지역에서 기록되었다. 46,000명의 수재민이 발생했고, 10,000,000 US$의 재산 피해였다. 이 폭우는 $21^{\circ}W,\;12^{\circ}S$에서 형성된 UTCV가 1월 내내 브라질 북동부 지역에 머물면서 영향을 미쳤기 때문이라는 것을 GOES 적외선 영상 분석으로 알 수 있었다. The eastern coast of northeastern Brazil (NEB), a coastal land-strip up to 300 km wide and stretching out from Rio Grande do Norte $(5^{\circ}S)$ State down to the south of Bahia State $(17^{\circ}S)$, experiences different rain producing systems, such as distrubances in the south-east trade winds, frontal systems penetration, land-sea breeze circulation and local convection associated with the topography and moisture flux convergence. The annual total rainfall ranges from 600 inland to 3000 mm on the coast. Rainfall totals 5 to 12 times the focal climatic means were recorded in various regions of Alagoas state in January 2004. It was estimated that 46,000 people were homeless, with material damages exceeding US$10 million as a consequence of the ensuing floods. GOES infrared images analysis showed that the main weather system responsible for this anomalously high rainfall totals was an Upper Troposphere Cyclonic Vortex (UTCV), which formed at about a $27^{\underline{\circ}}W\;e\;12^{\underline{\circ}}S$ and remained active for the entire month of January over NEB.

THE EFFECTS OF ORGANIZATIONAL AMBIDEXTERITY AND CO-CREATION ON ORGANIZATION PERFORMANCE

Maria de Lurdes Sarmento,Cl?udia Sim?es 글로벌지식마케팅경영학회 2023 Global Marketing Conference Vol.2023 No.07

The interest in the study of organizations’ ambidexterity (i.e., the capacity of combining organizational explorative and exploitative capabilities) entails expectations associated to its conceptual value and practical implications related to high-performing companies and long-term survival. In parallel, it is relevant to understand organizational ambidexterity under the marketing lenses, in particular, looking at the notion of co-creation and service-dominant logic. This study addresses the effects of organizational ambidexterity on organizational co-creation and evaluates whether these dynamics are different in SMEs and Large companies. We further assess how they contribute to the enhancement of firms’ performance. To the endeavor, we develop and empirically test a conceptual model.
