Protecting databases from schema disclosure: a CRUD-based protection model

Database schemas, in many organizations, are considered one of the critical assets to be protected. From database schemas, it is not only possible to infer the information being collected but also the way organizations manage their businesses and/or activities. One of the ways to disclose database schemas is through the Create, Read, Update and Delete (CRUD) expressions. In fact, their use can follow strict security rules or be unregulated by malicious users. In the first case, users are required to master database schemas. This can be critical when applications that access the database directly, which we call database interface applications (DIA), are developed by third party organizations via outsourcing. In the second case, users can disclose partially or totally database schemas following malicious algorithms based on CRUD expressions. To overcome this vulnerability, we propose a new technique where CRUD expressions cannot be directly manipulated by DIAs any more. Whenever a DIA starts-up, the associated database server generates a random codified token for each CRUD expression and sends it to the DIA that the database servers can use to execute the correspondent CRUD expression. In order to validate our proposal, we present a conceptual architectural model and a proof of concept.

A influência do processo de terceirização de tecnologia da informação na utilização dos modelos de contratação de serviços: um estudo de casos múltiplos

The change in the economic world and the emergence of Internet as a tool for communication and integration among the markets have forced organizations to adopt a different structure, process-oriented with a focus on information management. Thus, information technology has gained prominence in the organizational context, increasing its complexity and range of services provided by this function. Moreover, outsourcing has become an important model for flexible corporate structure, helping organizations to achieve better results when carrying out their activities and processes and be more competitive. To make the IT outsourcing, it is necessary to follow certain steps that range from strategic assessment to the management of outsourced service. Such steps can influence the form of contracting services, varying the types of service providers and contractors. Thus, the study aimed to identify how this IT outsourcing process influences the use of models for contracting services. For this, a study was conducted in multiple cases study involving two companies in Rio Grande do Norte State, specifically the health sector. Data collection was carried out with the CIOs of the companies surveyed through semi-structured interviews. According to the results obtained, it was found that the outsourcing process more structured influences the use of a more advanced contracting model. However, there are features found in these steps carrying more clearly this influence, as the goals pursued by outsourcing, the criteria used in selecting the supplier, a contract negotiation, how to transition services and the use of methods management, but can vary depending on the level of maturity in the relationship of the companies examined. Moreover, it was found that the use of contracting model may also influence how it is developed the IT outsourcing process, requiring or not its more formalized and organization

A NARRATIVE CASE STUDY EXAMINING THE EXPEREINCES OF MEN TEACHING SPECIAL EDUCATION IN THE ELEMENTARY GRADES

Over the past several decades, the landscape of the workplace has changed in many industrialized nations. In the United States this time period has seen the outright elimination or outsourcing of well-paying “blue collar” jobs. The workforce continues to evolve, change, and become more global, and men and women are making nontraditional occupational decisions, whether by choice or necessity. The traditional views of men and women have begun to shift. However, gender assumptions about masculinity have failed to keep pace with the shift. There are approximately 1.8 million elementary grade level teachers in United States public schools; of these, a mere 9% are male. The paucity of male teachers in the elementary grades has been a concern for many years. According to the Bureau of Labor Statistics, roughly 86% of all special education teachers are female. In 2012, 86.2% of all special education teachers were female, and by the following year, the number had dropped to 80.4%. The evidence indicates that more men are embarking on nontraditional career paths. Despite theses changes there is minimal research looking at the experiences of men working as special education teachers My goal in this study was to obtain a better understanding of the influences on and the process by which men make the decision to pursuing a career teaching special education in the elementary grades. The study utilized social role theory (Eagly, 1987), and Stead’s (2014) social constructionist theory as well as Williams’ (1992) glass escalator proposition The findings of this study confirm some of the factors related to career choice, experiences and barriers faced by men in nontraditional careers detailed in the literature. Three themes emerged for each research question: Experiences, advocacy, and benefits. Three themes emerged around the second research question exploring the experiences of men in a female-concentrated profession: The male body, communication, and perception. Three themes arose around the third research question: administration, My Masculinity, and pay. The findings run counter to Williams’ glass escalator proposition, which posits men working in female-concentrated professions are at an advantage. The findings advance support for Buschmeyer’s theory of (2013) alternative masculinity.

Comparação entre os sistemas de informação adquiridos e os desenvolvidos na Força Aérea

Os Sistemas de Informação (SI) que a Força Aérea (FA) explora são maioritariamente desenvolvidos internamente mas, com a redução cada vez maior do Orçamento para a Defesa, é fundamental um maior rigor na gestão de recursos e o aproveitamento de sinergias com o mundo civil, particularmente na área das Tecnologias de Informação (TI). A decisão de optar por SI comerciais é muitas vezes determinada por aspetos como a necessidade de reduzir custos, assegurar flexibilidade ou acompanhar o desenvolvimento tecnológico. Neste contexto esta investigação tem por objeto os SI utilizados pela FA e visa verificar em que medida é mais vantajoso para a FA continuar a desenvolver os SI que explora, ou se deverá privilegiar a sua aquisição garantindo sempre o cabal cumprimento da missão. Os resultados revelam que a experiência passada com SI comerciais é negativa, os custos elevados e a satisfação dos requisitos operacionais e prazos nem sempre foram atingidos, o que conduz à conclusão que a FA deverá continuar a desenvolver SI em todas as áreas em que os requisitos internos para um SI não tenham uma afinidade forte com o que existe disponível comercialmente. Abstract: Most of the Portuguese Air Force (PoAF) Information Systems currently in use are developed in-house, but with Defence Budget cuts it is imperative that Human Resources become thoroughly managed and synergies with the civilian world are established, particularly in the Information Technology field. The decision for commercial Information Systems is most of the time determined by the need to reduce costs, assure flexibility or keep up with technology. In this context this research aims to substantiate what is more adequate for the PoAF, continue to develop its Information Systems or give way to a commercial approach , never neglecting the PoAF main goal, its mission. The results show that previous experience with commercial Information Systems have been negative, the costs were high, and the operational requisites and deadlines many times have not been fulfilled. This leads to the conclusion that the PoAF should continue to develop its Information Systems in all the areas in which a commercial solution with identical requisites cannot be found.

Reconfigurations de la chaîne de valeur de l’industrie aéronautique au Québec : mises à niveau des processus et des compétences des entreprises sous-traitantes

Étude de cas comparative portant sur l'évolution de la chaîne de valeur aéronautique du grand Montréal. L'objet d'étude est le développement des capacités organisationnelles des firmes sous-traitantes grâce à des mises à niveau de leurs systèmes de production. Ces mises à niveau sont considérées s'inscrire dans un cadre stratégique en lien avec le positionnement de marché visé et générer des opportunités de formation et apprentissage. Un processus d'apprentissage commun aux firmes est relevé et présente des activités de conversion de savoir centrales au développement des compétences. Les analyses indiquent que des mises à niveau de fonction sont à favoriser pour élargir les capacités organisationnelles et l'offre de services correspondante de ces firmes jusqu’à l’atteinte du rang d’intégrateur. Le paradigme des chaînes de valeur et l’approche basée sur les ressources et l’apprentissage issu de la gestion stratégique sont agencés en continuum pour l’analyse des phénomènes.

Wage Matters & Globalization: South Florida’s Low-Wage Immigrant Plant Nursery Workers and Business Protectionism in the Age of Neoliberalism

Ornamental plant production in the State of Florida is an anomaly with respect to current theories of globalization and particularly their explanation of the employment of low-wage, immigrant labor. Those theories dictate that unskilled jobs that do not need to be performed within highly developed countries are outsourced to where labor is cheaper and more flexible. However, the State of Florida remains an important site of ornamental plant production in the US amidst a global economic environment of outsourcing and transnational corporate expansion. This dissertation relies on 50 semi-structured interviews with insiders of the Florida plant nursery industry, focus groups, and participant observation to explain how US trade, labor, and migration policy-making at local levels are not removed from larger global processes taking place in the world since the 1970s. In Florida, elite market players of the plant nursery industry have been able to resist global trends in free trade, operating instead in a protected market. They have done this by appealing to scientific justifications and through arbitrary implementations of neoliberal ideology that keeps small and middle range business alive, while maintaining a seemingly endless supply of marginalized and exploited low-wage, immigrant workers.
