O papel da tecnologia da informação e comunicação na inclusão financeira da população ribeirinha da Ilha de Marajó: o caso Agência Barco

O desafio de ofertar infraestrutura de serviços públicos nas regiões menos desenvolvidas do Brasil, geralmente mais afastadas dos grandes centros urbanos, mobiliza setores da sociedade na busca de abordagens novas e criativas que possam diminuir as grandes disparidades inter-regionais. Uma das carências vivenciadas por parte da população brasileira é a falta de acesso ao sistema financeiro, comprometendo a capacidade de plena participação dessas pessoas na economia, dificultando a geração e acúmulo de riqueza, situação essa presente na Ilha de Marajó, no estado do Pará, cuja maioria de seus dezesseis municípios apresenta Índice de Desenvolvimento Humano (IDH) baixo ou muito baixo. Para mudar essa realidade, uma iniciativa inovadora é a agência bancária itinerante instalada em barco, para atendimento a populações ribeirinhas de regiões com vasta extensão territorial, baixa densidade demográfica, dificuldades de transporte e limitações na oferta de tecnologia da informação e comunicação (TIC). Assim, essa pesquisa, com propósito exploratório e descritivo, tem como objetivo principal identificar, sob o ponto de vista das TIC, como os indicadores de inclusão financeira são influenciados pela atuação da Agência Barco na Ilha de Marajó. Além do estudo teórico, foi realizada investigação empírica, por meio de observação direta e entrevistas semiestruturadas com clientes e funcionários da Agência Barco, realizadas ao longo de quatro dias, em duas cidades da Ilha de Marajó. Para análise dos dados, foram aplicadas técnicas de análise de conteúdo às entrevistas, com objetivo de identificar a presença de elementos de inclusão financeira, transpondo os resultados para um modelo heurístico de infoinclusão dinâmica (2iD), o qual foi adaptado para contemplar constructos de inclusão financeira. O resultado da pesquisa demonstra que a Agência Barco consegue suprir as necessidades de acesso a serviços e produtos financeiros pela população da Ilha de Marajó, ao mesmo tempo em que se identifica oportunidades para ampliação de aspectos relacionados à educação financeira, possibilitando fortalecer os componentes dinâmicos do processo de inclusão financeira, com aumento da conscientização e consequente aumento da demanda por serviços e produtos financeiros.

Official Central Bank Interventions in the Foreign Exchange Markets: A DCC Approach with Exogenous Variables

This paper assesses the impact of official central bank interventions (CBIs) on exchange rate returns, their volatility and bilateral correlations. By exploiting the recent publication of intervention data by the Bank of England, this study is able to investigate fficial interventions by a total number of four central banks, while the previous studies have been limited to three (the Federal Reserve, Bundesbank and Bank of Japan). The results of the existing literature are reappraised and refined. In particular, unilateral CBI is found to be more successful than coordinated CBI. The likely implications of these findings are then discussed.

Submerged Vanes for Flow Control and Bank Protection in Streams, HR-255, 1984

This study was conducted for the purpose of evaluating a new concept for a bank-protection structure: The Iowa Vane . The underlying idea involves countering the torque exerted on the primary flow by its curvature and vertical velocity gradient, thereby eliminating or significantly reducing the secondary flow and thus reducing the undermining of the outer banks and the high-velocity attack on it. The new structure consists of an array of short, vertical, submerged vanes installed with a certain orientation on the channel bed. A relatively small number of vanes can produce bend flows which are practically uniform across the channel. The height of the vanes is less than half the water depth, and their angle with the flow direction is of the order of l0 degrees. In this study, design relations have been established. The relations, and the vanes' overall performance, have been tested in a laboratory model under different flow and sediment conditions. The results are used for the design of an Iowa-Vane bank protection structure for a section of East Nishnabotna River along U.S. Highway 34 at Red Oak, Iowa.

Monitoring bank performance in the presence of risk

This paper proposes a managerial control tool that integrates risk in efficiency scores. Building on existing efficiency specifications, our proposal reflects the real banking technology and accurately models the relationship between desirable and undesirable outputs. Specifically, the undesirable output is defined as non-performing loans to capture credit risk, and is linked only to the relevant dimension of the output set. We empirically illustrate how our efficiency measure functions for managerial control purposes. The application considers a unique dataset of Costa Rican banks during 1998-2012. Efficiency scores? implications are mostly discussed at bank-level, and their interpretations are enhanced by using accounting ratios. We also show the usefulness of our tool for corporate governance by examining performance changes around executive turnover. Results confirm that appointing CEOs from outside the bank significantly improves performance, thus suggesting the potential benefits of new organisational practices.

Riparian vegetation affected by bank erosion in the Lower São Francisco River, Northeastern Brazil

Changes in the hydrological regime of the Lower São Francisco River, located in Northeastern Brazil have brought negative environmental impacts, jeopardizing the flora and fauna of a global biodiversity hotspot, due to implementation of hydroelectric power dams and surface water withdrawal for irrigation in public and private perimeters. Remnants of the riparian stratum associated to the riverbank destabilization in six fragments were studied by surveying trees, shrubs, herbs, and aquatic species. The calculation of the Factor of Safety (FS) was performed in order to understand the riverbank's stability related to soil texture and vegetation cover. An overall number of 51 botanic families distributed in 71 genera and 79 species were recorded, predominantly from the families Mimosaceae, Myrtaceae, and Fabaceae. The fragmented riparian vegetation is mostly covered by secondary species under a strong anthropogenic impact such as deforestation, mining and irrigation, with an advanced erosion process in the river margins. Strong species that withstand the waves present in the river flow are needed to reduce the constant landslides that are mainly responsible for the river sedimentation and loss of productive lands. A lack of preservation attitude among the local landholders was identified, and constitutes a continuing threat to the riparian ecosystem biodiversity.

Lolium multiflorum seeds in the soil: I. Soil seed bank dynamics in a no til system

The objective of the study was to characterize annual ryegrass seed population dynamics, managed for natural re-sowing, in no til systems in rotation with soybean, in different chronosequences An area was cultivated for two years with soybean, left as fallow land for the next two years and then cultivated again with soybean for the next two years. The four chronosequences represented different management periods, two with soybean (6 and 8 years old) and the other two resting (3 and 9 years old). Soil samples were taken every month during one year and divided into two depths (0-5 and 5-10 cm). Vegetation dynamics were also evaluated (number of plants, inflorescences and seedlings). Soil seed bank (SSB) dynamics showed structural patterns in time, with a "storage period" in summer, an "exhausting period" during autumn and a "transition period" in winter and spring. Pasture establishment by natural re-sowing was totally dependent on the annual recruitment of seeds from the soil. The influence of the management practices on the SSB was more important than the number of years that these practices had been implemented. Places where soybean was sown showed the largest SSBs. Most of the seeds overcame dormancy and germinated at the end of the summer and beginning of the autumn, showing a typically transitory SSB, but with a small proportion of persistent seeds

Training to address attitudes and behaviour of rural bank managers in Madhya Pradesh, India: A programme to facilitate financial inclusion

Given their physical presence in India, banks are arguably well-placed to improve financial inclusion in rural areas. However, uncertain repayment capacities and high transaction costs mean formal financial institutions are often reluctant to lend to the rural poor. Conversely, high transaction costs in dealing with banks are also incurred by clients, through, for example, lengthy, cumbersome and potentially ignominious procedures. Negative attitudes towards poor clients can be an important component of such transaction costs. An applied research project funded by the Enterprise Development Innovation Fund (EDIF-DFID) developed an innovative training programme designed to encourage more positive attitudes of bank staff towards poor clients, and towards their own role in rural poverty alleviation and development. This paper examines the development of the training programme, its implementation, and the results of its evaluation. It is shown that training can bring about attitudinal change, which in turn is reflected in behaviour and social impact.

Bank efficiency in Brazil: the importance for economic sustainability

Studies on efficiency achieved greater relevance in organisations within an open market framework, which in Brazil began around 1990. The objective of this paper, applying the data envelopment analysis methodology, is to analyse the efficiency of banks operating in the country using the database termed 'the biggest banks', periodically divulged by the Central Bank of Brazil in 2010-2012. The methodology was applied to the 26 largest banking organisations via two approaches, one was financial intermediation and the other was results. In the financial intermediation approach, the efficiency increase was the highest among banks specialised in credit from 2010 to 2012. Retail banks, especially the large ones, felt most intensely the reaction of 2011, a year considered as the sector's low performance year. In the results approach, the efficiency increase was higher among retail banks. Factors such as retractions in the SELIC rate and bank spreads impacted all banks, regardless of the segment.

Identifizierung und Charakterisierung von Zielantigenen alloreaktiver zytotoxischer T-Zellen mittels cDNA-Bank-Expressionsklonierung in akuten myeloischen Leukämien

Allogene hämatopoetische Stammzelltransplantationen (HSZTs) werden insbesondere zur Behandlung von Patienten mit Hochrisiko-Leukämien durchgeführt. Dabei bewirken T-Zellreaktionen gegen Minorhistokompatibilitätsantigene (mHAgs) sowohl den therapeutisch erwünschten graft-versus-leukemia (GvL)-Effekt als auch die schädigende graft-versus-host (GvH)-Erkrankung. Für die Identifizierung neuer mHAgs mittels des T-Zell-basierten cDNA-Expressionsscreenings waren leukämiereaktive T-Zellpopulationen durch Stimulation naïver CD8+-T-Lymphozyten gesunder HLA-Klasse I-identischer Buffy Coat-Spender mit Leukämiezellen von Patienten mit akuter myeloischer Leukämie (AML) generiert worden (Albrecht et al., Cancer Immunol. Immunother. 60:235, 2011). Im Rahmen der vorliegenden Arbeit wurde mit diesen im AML-Modell des Patienten MZ529 das mHAg CYBA-72Y identifiziert. Es resultiert aus einem bekannten Einzelnukleotidpolymorphismus (rs4673: CYBA-242T/C) des Gens CYBA (kodierend für Cytochrom b-245 α-Polypeptid; syn.: p22phox), der zu einem Austausch von Tyrosin (Y) zu Histidin (H) an Aminosäureposition 72 führt. Das mHAg wurde von T-Lymphozyten sowohl in Assoziation mit HLA-B*15:01 als auch mit HLA-B*15:07 erkannt. Eine allogene T-Zellantwort gegen CYBA-72Y wurde in einem weiteren AML-Modell (MZ987) beobachtet, die ebenso wie in dem AML-Modell MZ529 polyklonal war. Insgesamt konnte bei drei von fünf getesteten HLA-B*15:01-positiven Buffy Coat-Spendern, die homozygot für CYBA-72H (H/H) waren, eine CYBA-72Y-spezifische T-Zellantwort generiert werden. Das von den T-Lymphozyten übereinstimmend in niedrigster Konzentration erkannte Peptid umfasste die Aminosäuren 69 - 77, wobei das homologe Peptid aus CYBA-72H auch in hohen Konzentrationen keine Reaktivität auslöste. Eine reziproke Immunogenität des mHAg ist bislang nicht belegt. T-Lymphozyten gegen CYBA-72Y erkannten Leukämiezellen bei acht von zwölf HLA-B*15:01-positiven Patienten (FAB-Subtypen: M1, M2, M4, M5). Da das Gen CYBA für eine Komponente des mikrobiziden Oxidasesystems von phagozytierenden Zellen kodiert, ist es überwiegend in Zellen des hämatopoetischen Systems exprimiert. Von Leukozytensubtypen, aufgereinigt aus HLA-B*15:01-positiven Buffy Coat-Spendern mit CYBA-242T-Allel, wurden Monozyten und daraus abgeleitete dendritische Zellen durch CYBA-72Y-reaktive T-Lymphozyten sehr stark, untransformierte B-Zellen in weit geringerem Maße und Granulozyten sowie T-Lymphozyten nicht erkannt. Das für CYBA-72Y kodierende Allel CYBA-242T wurde bei 56% aller getesteten gesunden Spender und Malignompatienten (n=481) nachgewiesen. Unter Berücksichtigung der Häufigkeit des präsentierenden HLA-Allels ist davon auszugehen, dass etwa 4,5% der Kaukasier das mHAg CYBA-72Y zusammen mit HLA-B*15:01 tragen. Nach bisherigen Beobachtungen führt ein immunogener CYBA-72Y-Mismatch bei allogenen HSZTs nicht notwendigerweise zu einer schweren GvH-Erkrankung. Das hier beschriebene mHAg CYBA-72Y erscheint potenziell geeignet, im Rahmen einer allogenen HSZT die präferenzielle Elimination der Empfänger-Hämatopoese unter Einschluss von myeloischen Leukämiezellen zu bewirken. Jedoch sind weiterführende Untersuchungen erforderlich, um die therapeutische Relevanz des Antigens zu belegen.
