Entrepreneurship among female immigrants. A case study in Madrid

The primary objective of this paper is to study and understand which factors determine the use or the non-use of ethnic resources in the business strategies of immigrant business women in Madrid. To achieve this goal, we studied the relationship between the structural factors of the host society, the resources that may be available to immigrant women in the context of their ethnic communities, and other individual characteristics. In this study, it is used a qualitative approach. We conducted 27 semi-structured interviews with immigrant entrepreneurs from Latin America (Brazil, the Dominican Republic, Ecuador, Venezuela, Bolivia, Paraguay, and Peru), Africa (Morocco and Senegal), and Eastern Europe (Bulgaria and Romania). The main conclusions reveal that the difference regarding the use of ethnic resources lies in the following factors: social networks, legal status, having access to ethnic resources, business location, and entrepreneur women’s origin.pre-print229 K

Who’s Got Your Mail?:Characterizing Mail Service Provider Usage

E-mail has long been a critical component of daily communication and the core medium for modern business correspondence. While traditionally e-mail service was provisioned and implemented independently by each Internet-connected organization, increasingly this function has been outsourced to third-party services. As with many pieces of key communications infrastructure, such centralization can bring both economies of scale and shared failure risk. In this paper, we investigate this issue empirically --- providing a large-scale measurement and analysis of modern Internet e-mail service provisioning. We develop a reliable methodology to better map domains to mail service providers. We then use this approach to document the dominant and increasing role played by a handful of mail service providers and hosting companies over the past four years. Finally, we briefly explore the extent to which nationality (and hence legal jurisdiction) plays a role in such mail provisioning decisions

Forward Pass: On the Security Implications of Email Forwarding Mechanism and Policy

The critical role played by email has led to a range of extension protocols (e.g., SPF, DKIM, DMARC) designed to protect against the spoofing of email sender domains. These protocols are complex as is, but are further complicated by automated email forwarding -- used by individual users to manage multiple accounts and by mailing lists to redistribute messages. In this paper, we explore how such email forwarding and its implementations can break the implicit assumptions in widely deployed anti-spoofing protocols. Using large-scale empirical measurements of 20 email forwarding services (16 leading email providers and four popular mailing list services), we identify a range of security issues rooted in forwarding behavior and show how they can be combined to reliably evade existing anti-spoofing controls. We show how this allows attackers to not only deliver spoofed email messages to prominent email providers (e.g., Gmail, Microsoft Outlook, and Zoho), but also reliably spoof email on behalf of tens of thousands of popular domains including sensitive domains used by organizations in government (e.g., state.gov), finance (e.g., transunion.com), law (e.g., perkinscoie.com) and news (e.g., washingtonpost.com) among others

O BANQUEIRO DA RESISTÊNCIA: UMA ANÁLISE FÍLMICA

As decisões estão presentes no cotidiano, tanto para questões fáceis quanto para as complexas, sendo que para a tomada de decisão alguns aspectos são mais relevantes que outros, um exemplo disso são as preferências. O presente estudo possui como objetivo a análise fílmica do filme O Banqueiro da Resistência, de modo a identificar tais aspectos de processo decisório. O presente estudo foi realizado se utilizando de pesquisa bibliográfica para trazer os conceitos de processo decisório e racionalidade limitada, seguido pela observação crítica das cenas do filme para identificar os aspectos estudados e por fim realizou-se a análise do filme tendo como contraponto os conceitos inicialmente explicados. Após a finalização do estudo, notou-se que as decisões são tomadas principalmente com base nas preferências individuais, além do grande peso do viés emocional. Isso se deve também à racionalidade limitada que cada indivíduo possui

Prioritizing Security Practices via Large-Scale Measurement of User Behavior

Security is an ever growing concern for daily Internet users, especially sincemany facets of a user's daily interactions (banking, commerce, workplace) are now accessed via the Internet. Fortunately, recent technical advancements – such as encrypted web browsing, email spam filtering, and login two factor authentication – have increased the accessibility and practicality of security for users. However, studies show that the majority of exploited attacks take advantage of the human in the loop. Technology and humans are required to work in harmony for security to be effective. As a result, it is crucial that we understand the extent to which users follow best practices, and that we evaluate whether their behaviors in fact help prevent adverse security outcomes. In this dissertation, I argue that large-scale empirical measurement is a practical and effective technique to answer these questions as the basis for prioritizing security practices, and I support this argument with three different projects. First, I use network traffic data and measurement methods to quantify user behavior ``best practices'' and how they relate to an outcome (in this case, compromise). Next I examine how communication about a security policy change can affect an organization by analyzing large-scale organizational data. Finally, I quantify attacker behavior in the “Hack for Hire” market by hiring and monitoring attackers, which provides insight into which defenses to prioritize for better protecting users from these types of attacks. By empirically understanding and prioritizing effective security practices, we can further improve security for users

Catalogación y Normalización de datos de Infraestructura espacial de Santa Cruz

El objetivo del presente trabajo es la construcción de un marco organizativo que permita elaborar información cartográfica interoperable, visualizable y publicable en un catálogo respetando lineamientos y lenguajes cartográficos de acuerdo a las normas de calidad especificadas en ISO/TC211.La información geográfica (IG) constituye la base para el desarrollo de nuevas líneas de trabajo orientadas a aprovechar de manera eficiente los recursos naturales renovables, evaluar las posibilidades económicas de su explotación y el valor que poseen para la sociedad en su conjunto. En virtud de que la provincia de Santa Cruz presenta graves problemas ambientales relacionados con la fragmentación de hábitat y pérdida de biodiversidad por el avance de los procesos erosivos, la primera etapa se centró en la información de recursos hídricos superficiales de la Provincia, como base para el desarrollo de nuevas líneas de trabajo de gran pertinencia social y ambiental.Los resultados del trabajo sientan las bases generales de carácter normativo conforme a las cuales se establecerán las acciones de integración de la IG producida en el Laboratorio de Cartografía, Teledetección y SIG de la UARG – UNPA
