A Comparison of Geo-tagging in Mobile Internet Browsing Applications on iOS and Android.

Nowadays there is almost no crime committed without a trace of digital evidence, and since the advanced functionality of mobile devices today can be exploited to assist in crime, the need for mobile forensics is imperative. Many of the mobile applications available today, including internet browsers, will request the user���s permission to access their current location when in use. This geolocation data is subsequently stored and managed by that application's underlying database files. If recovered from a device during a forensic investigation, such GPS evidence and track points could hold major evidentiary value for a case. The aim of this paper is to examine and compare to what extent geolocation data is available from the iOS and Android operating systems. We focus particularly on geolocation data recovered from internet browsing applications, comparing the native Safari and Browser apps with Google Chrome, downloaded on to both platforms. All browsers were used over a period of several days at various locations to generate comparable test data for analysis. Results show considerable differences not only in the storage locations and formats, but also in the amount of geolocation data stored by different browsers and on different operating systems.

Pr��tica de ensino supervisionada em Educa����o Pr��-escolar e Ensino do 1.�� Ciclo do Ensino B��sico

O presente relat��rio foi realizado no ��mbito da Unidade Curricular de Pr��tica de Ensino Supervisionada (PES), integrada no curso de Mestrado em Educa����o Pr��-escolar (EPE) e Ensino do 1.�� Ciclo do Ensino B��sico (1.�� CEB) e desenvolvida em contexto de Educa����o Pr��-escolar, numa Institui����o Particular de Solidariedade Social, com crian��as de 3 anos de idade e em contexto do 1.�� Ciclo do Ensino B��sico, numa escola da rede p��blica com um grupo/turma de crian��as de 5 e 6 anos de idade. A pr��tica foi desenvolvida nos dois contextos, e os dados foram retirados no decorrer das interven����es realizadas atrav��s da observa����o direta e participante, sendo que para a recolha de dados recorremos a notas de campo, registos fotogr��ficos e de ��udio e, ainda, ��s produ����es das crian��as, com a intencionalidade de nos servirem como documentos de an��lise. Ao longo do processo fomos tamb��m realizando registos numa grelha de observa����o, adaptada de Viana e Ribeiro (2014), para podermos compreender a evolu����o das crian��as no desenvolvimento das suas compet��ncias (meta)lingu��sticas. Partimos da quest��o-problema: Que estrat��gias de aprendizagem se podem desenvolver em contexto de Educa����o Pr��-escolar e de 1.�� Ciclo Ensino B��sico, no sentido de desenvolver compet��ncias (meta)lingu��sticas? Considerando esta interroga����o estabelecemos como objetivo: (i) Promover o desenvolvimento lingu��stico e metalingu��stico das crian��as num contexto geral de comunica����o (oralidade, escrita e leitura). O estudo ajusta-se a uma abordagem qualitativa. Para que fosse poss��vel recolhermos a informa����o para a presente investiga����o foi necess��rio selecionarmos um conjunto de t��cnicas e de instrumentos de recolha de dados. Durante as atividades que desenvolvemos proporcionamos um ambiente positivo, facilitador da explora����o de situa����es diversificadas de escrita e leitura e propiciamos, tamb��m, oportunidades para que cada crian��a fosse ouvida, respeitada e integrada. Em termos de resultados pensamos poder concluir que nos dois contextos atendemos aos interesses e motiva����es das crian��as, de modo a promover estrat��gias de aprendizagens de forma a desenvolver compet��ncias (meta)lingu��sticas, como se comprova pela an��lise dos dados obtidos atrav��s das grelhas de observa����o, bem como nas experi��ncias de ensino e aprendizagem que integramos neste documento e que tamb��m d��o conta do processo vivenciado ao longo da Pr��tica de Ensino Supervisionada.

Do tratamento das reclama����es �� gest��o da insatisfa����o: o comportamento de empresas hoteleiras mediante a insatisfa����o de seus clientes

Consumer dissatisfaction, when properly handled, is a significant information source for the manager. Studies in this area allow broadening the understanding of certain customer attitudes and behaviors, such as loyalty, repurchase intention or satisfaction and trust increase. Above and beyond supporting consumer feedback, dissatisfaction can provide significant opportunities for organizational learning. Starting from dissatisfied customer information, companies can detect service flaws and develop new products. This work presents the results of an investigation on the behavior of businesses belonging to the hotel sector in Natal, RN, through the dissatisfaction of their customers. We have sought to map the main problems presented by customers to hotels, in the perception of managers and employees, as well as to understand both the process of dissatisfactionrelated data collection, analysis, and processing, and the utilization of such information by businesses. Beyond this, we have compared the habits of organizations to the company reaction approaches described in the literature: Complaint Handling, Complaint Management, and Dissatisfaction Management. The used methodology has been based on case study. Data was collected via indepth interviews with managers and employees in six hotels, two independent ones and four belonging to national and international hotel networks. We have also made use of documents provided by the organizations, such as guest complaint registers and reports from satisfaction surveys on which content analysis was subsequently performed. The results of the investigation point to a high level of awareness in the companies concerning the importance of consumer dissatisfaction. Even though the maximum grade in the procedure scale is not achieved, it has been observed that answer to dissatisfaction is given in planned and systematic form, geared towards consumer satisfaction and improvement of products and processes. Hotel businesses still have to look into other possibilities for mapping consumer dissatisfaction, which implies, among other aspects, articulation with a range of public and private organizations in such a way as to guarantee sustainability of touristic activities in the long term

Otimiza����o dos par��metros de maquinagem no processo de fresagem

Cada vez mais, os principais objetivos na ind��stria �� a produ����o a baixo custo, com a m��xima qualidade e com o tempo de fabrico o mais curto poss��vel. Para atingir esta meta, a ind��stria recorre, frequentemente, ��s m��quinas de comando num��rico (CNC), uma vez que com esta tecnologia torna se capaz alcan��ar uma elevada precis��o e um tempo de processamento mais baixo. As m��quinas ferramentas CNC podem ser aplicadas em diferentes processos de maquinagem, tais como: torneamento, fresagem, fura����o, entre outros. De todos estes processos, o mais utilizado �� a fresagem devido �� sua versatilidade. Utiliza-se normalmente este processo para maquinar materiais met��licos como �� o caso do a��o e dos ferros fundidos. Neste trabalho, s��o analisados os efeitos da varia����o de quatro par��metros no processo de fresagem (velocidade de corte, velocidade de avan��o, penetra����o radial e penetra����o axial), individualmente e a intera����o entre alguns deles, na varia����o da rugosidade num a��o endurecido (a��o 12738). Para essa an��lise s��o utilizados dois m��todos de otimiza����o: o m��todo de Taguchi e o m��todo das superf��cies. O primeiro m��todo foi utilizado para diminuir o n��mero de combina����es poss��veis e, consequentemente, o n��mero de ensaios a realizar �� denominado por m��todo de Taguchi. O m��todo das superf��cies ou m��todo das superf��cies de resposta (RSM) foi utilizado com o intuito de comparar os resultados obtidos com o m��todo de Taguchi, de acordo com alguns trabalhos referidos na bibliografia especializada, o RSM converge mais rapidamente para um valor ��timo. O m��todo de Taguchi �� muito conhecido no setor industrial onde �� utilizado para o controlo de qualidade. Apresenta conceitos interessantes, tais como robustez e perda de qualidade, sendo bastante ��til para identificar varia����es do sistema de produ����o, durante o processo industrial, quantificando a varia����o e permitindo eliminar os fatores indesej��veis. Com este m��todo foi vi constru��da uma matriz ortogonal L16 e para cada par��metro foram definidos dois n��veis diferentes e realizados dezasseis ensaios. Ap��s cada ensaio, faz-se a medi����o superficial da rugosidade da pe��a. Com base nos resultados obtidos das medi����es da rugosidade �� feito um tratamento estat��stico dos dados atrav��s da an��lise de vari��ncia (Anova) a fim de determinar a influ��ncia de cada um dos par��metros na rugosidade superficial. Verificou-se que a rugosidade m��nima medida foi de 1,05���m. Neste estudo foi tamb��m determinada a contribui����o de cada um dos par��metros de maquinagem e a sua intera����o. A an��lise dos valores de ���F-ratio��� (Anova) revela que os fatores mais importantes s��o a profundidade de corte radial e da intera����o entre profundidade de corte radial e profundidade de corte axial para minimizar a rugosidade da superf��cie. Estes t��m contribui����es de cerca de 30% e 24%, respetivamente. Numa segunda etapa este mesmo estudo foi realizado pelo m��todo das superf��cies, a fim de comparar os resultados por estes dois m��todos e verificar qual o melhor m��todo de otimiza����o para minimizar a rugosidade. A metodologia das superf��cies de resposta �� baseada num conjunto de t��cnicas matem��ticas e estat��sticas ��teis para modelar e analisar problemas em que a resposta de interesse �� influenciada por diversas vari��veis e cujo objetivo �� otimizar essa resposta. Para este m��todo apenas foram realizados cinco ensaios, ao contr��rio de Taguchi, uma vez que apenas em cinco ensaios consegue-se valores de rugosidade mais baixos do que a m��dia da rugosidade no m��todo de Taguchi. O valor mais baixo por este m��todo foi de 1,03��m. Assim, conclui-se que RSM �� um m��todo de otimiza����o mais adequado do que Taguchi para os ensaios realizados. Foram obtidos melhores resultados num menor n��mero de ensaios, o que implica menos desgaste da ferramenta, menor tempo de processamento e uma redu����o significativa do material utilizado.

Sistemas de gerenciamento de bibliotecas: riscos decorrentes do processo de migra����o de dados

This work aims to analyze risks related to information technology (IT) in procedures related to data migration. This is done considering ALEPH, Integrated Libray System (ILS) that migrated data to the Library Module present in the software called Sistema Integrado de Gest��o de Atividades Acad��micas (SIGAA) at the Zila Mamede Central Library at the Federal University of Rio Grande do Norte (UFRN) in Natal/Brazil. The methodological procedure used was of a qualitative exploratory research with the realization of case study at the referred library in order to better understand this phenomenon. Data collection was able once there was use of a semi-structured interview that was applied with (11) subjects that are employed at the library as well as in the Technology Superintendence at UFRN. In order to examine data Content analysis as well as thematic review process was performed. After data migration the results of the interview were then linked to both analysis units and their system register with category correspondence. The main risks detected were: data destruction; data loss; data bank communication failure; user response delay; data inconsistency and duplicity. These elements point out implication and generate disorders that affect external and internal system users and lead to stress, work duplicity and hassles. Thus, some measures were taken related to risk management such as adequate planning, central management support, and pilot test simulations. For the advantages it has reduced of: risk, occurrence of problems and possible unforeseen costs, and allows achieving organizational objectives, among other. It is inferred therefore that the risks present in data bank conversion in libraries exist and some are predictable, however, it is seen that librarians do not know or ignore and are not very worried in the identification risks in data bank conversion, their acknowledge would minimize or even extinguish them. Another important aspect to consider is the existence of few empirical research that deal specifically with this subject and thus presenting the new of new approaches in order to promote better understanding of the matter in the corporate environment of the information units

Systematic reviews as a tool for planning and interpreting trials

Background Systematic reviews followed by ameta-analysis are carried out in medical research to combine the results of two or more related studies. Stroke trials have struggled to show beneficial effects and meta-analysis should be used more widely throughout the research process to either speed up the development of useful interventions, or halt more quickly research with hazardous or ineffective interventions. Summary of review. This review summarises the clinical research process and illustrates how and when systematic reviews may be used throughout the development programme. Meta-analyses should be performed after observational studies, preclinical studies in experimental stroke, and after phase I, II, and III clinical trials and phase IV clinical surveillance studies. Although meta-analyses most commonly work with summary data, they may be performed to assess relationships between variables (meta-regression) and, ideally, should utilise individual patient data. Meta-analysis techniques may alsoworkwith ordered categorical outcome data (ordinal meta-analysis) and be used to perform indirect comparisons where original trial data do not exist. Conclusion Systematic review/meta-analyses are powerful tools in medical research and should be used throughout the development of all stroke and other interventions

A lideran��a e suas rela����es com o comprometimento organizacional

This study presents the results of field research of an exploratory descriptive character that seeks to identify the latent dimensions of leadership and organizational commitment as well as to discover the relationship between these two sets of indicators. In the study, 236 respondents were interviewed, 84 being managers or owners and 152 being sales personnel. The research was undertaken in five shopping centers in the municipality of Natal, capital of Rio Grande do Norte, and employed two different questionnaires. One of them was developed by Bass and Avolio, 1992 (in NORTHOUSE, 2004), contained 21 indicators of leadership and was completed by store managers. The other instrument, completed by sales personnel in the stores, was developed by Medeiros, Albuquerque, Marques and Siqueira (2003) and contained a total of 28 indicators of organizational commitment. For the analysis of the data, factor analysis techniques and structural equations modeling were used. Using the factor analysis, five dimensions of leadership and seven dimensions of organizational commitment were found, all of which have a theoretical basis for their explanation. Through the structural equations modeling, a relationship was established between leadership and organizational commitment, in which it was possible to observe that certain leadership styles influence in a positive form the commitment of the employee

Prevalence of chronic diseases in private healthcare sector of South Africa: A threat to public health

Purpose: To evaluate the prevalence of patients suffering from registered chronic disease list (CDL) conditions in a section of the South African private health sector from 2008 - 2012. Methods: This study was a retrospective analysis of the medicine claims database of a nationally (South African) representative Pharmacy Benefit Management (PBM) company data between 2008 and 2012. Statistical analysis was used to analyse the data. Descriptive analysis was performed to calculate the prevalence of CDL conditions for the entire population, and stratified by age and gender. However, MIXED linear modelling was used to determine changes in the average number of CDL conditions per patient, adjusted for age and gender from 2008 - 2012. Results: An increase of 0.20 in chronic diseases was observed from 2008 - 2012 in patients having any CDL condition, with an average of 1.57 (1.57 - 1.58, 95 % CI) co-morbid CDL conditions in 2008 and 1.77 (1.77 - 1.78, 95 % CI) in 2012. This increase in average number of CDL conditions per patient between 2008 and 2012 was statistically significant (p < 0.05), but with no large practical significance (d < 0.8). Conclusion: Prevalence of patients with CDL conditions along with risk of co-morbidity has been increasing with time in the private health sector of South Africa. Risk of increased co-morbidity with age and among different genders was prevalent.

Gest��o compartilhada de P&D em petr��leo:a intera����o entre a Petrobr��s e a Universidade Federal do Rio Grande do Norte

This work addresses the relationship between University-Firm aims to understand the model of shared management of R&D in petroleum of Petrobras with UFRN. This is a case study which sought to investigate whether the model of cooperation established by the two institutions brings innovation to generate technical-scientific knowledge and contribute to the coordination with other actors in the promotion of technological innovation. In addition to desk research the necessary data for analysis were obtained by sending questionnaires to the coordinators of projects in R&D at the company and university. Also, interviews were conducted with subjects who participated in the study since its inception to the present day. This case study were analysed through the Resource-Based View and Interorganizational Networks theory. The sample data also stands that: searches were aligned to the strategic planning and that 29% of R&D projects have been successful on the scope of the proposed objectives (of which 11% were incorporated into business processes); which was produced technical and scientific knowledge caracterized by hundreds of national and international publications; thesis, dissertations, eleven patents, and radical and incremental innovations; the partnership has also brought benefits to the academic processes induced by the improved infrastructure UFRN and changing the "attitude" of the university (currently with national prominence in research and staff training for the oil sector). As for the model, the technical point of view, although it has some problems, it follows that it is appropriate. From the viewpoint of the management model is criticized for containing an excess of bureaucracy. From the standpoint of strategic allocation of resources from the legal framework needs to be reassessed, because it is focused only on the college level and it is understood that should also reach the high school given the new reality of the oil sector in Brazil. For this it is desirable to add the local government to this partnership. The set of information leads to the conclusion that the model is identified and named as a innovation of organizational arrangement here known as Shared Management of R&D in petroleum of Petrobras with UFRN. It is said that the shared management model it is possible to exist, which is a simple and effective way to manage partnerships between firms and Science and Technology Institutions. It was created by contingencies arising from regulatory stand points and resource dependence. The partnership is the result of a process of Convergence, Construction and Evaluation supported by the tripod Simplicity, Systematization and Continuity, important factors for its consolidation. In practice an organizational arrangement was built to manage innovative university-industry partnership that is defined by a dyadic relationship on two levels (institutional and technical, therefore governance is hybrid), by measuring the quarterly meetings of systematic and standardized financial contribution proportional to the advancement of research. These details have led to the establishment of a point of interaction between the scientific and technological-business dimension, demystifying they are two worlds apart

Adherence to therapeuthic regimen and metabolic control of type 1 diabetes

Abstract Objectives: To assess the adherence to therapeutic regimen; to determine the Hemoglobin Glycation Index (HbA1c); to analyse the relationship that exists between the adherence to therapeutic regimen and metabolic control. Design: correlational analytical study, carried out according to a cross-sectional perspective. Participants: A non-probabilistic sample of 266 people with type 1 diabetes aged between 18 and 78 years old (mean M = 51.02 �� SD = 18.710), attending follow-up diabetes consultations. Mostly male individuals (51.88%), with low schooling level (50.75% had only inished elementar school). Measuring Instruments: We used the following data collection tools: a questionnaire on clinical and socio-demographic data, blood analysis of venous blood to determine the glycated hemoglobin level (HbA1c).Three self-report scales were used: Accession to Diabetes Treatment (Matos, 1999), Self-perception Scale (Vaz Serra, 1986) and Social Support Scale (Matos & Rodrigues, 2000). Results: In a sample in which the mean disease duration is 12.75 years, 69.17% of the sample run glycemic control tests between once a day and four times a year and 42.86% of them undergo insulin treatment. In the last 3 weeks, 26.32% of these people have experienced an average of 4.22 to 44.36%, hypoglycemic crises and experienced an average of 6.18 hyperglycemic crises. 57% of the individuals have showed a poor metabolic control (mean HbA1c higher than 7.5% (HbA1c mean M ��� 7.50%). The mean psychosocial proile revealed individuals who show a decent self-esteem (M = 70.81) and acceptable social support (M = 58.89). Conclusions: The results suggest we should develop a kind of investigation that could be used to monitor the strenght of the mediation effect effect of the psychosocial predictive dimension of the adherence, since it has become essential to support a multidisciplinary approach which center lays in the promotion of a co-responsible self-management from the person who suffers from diabetes. This will enable a better quality of life; fewer years of people���s lives lost prematurely and a better health with less economical costs for citizens and healthcare systems.

Educated to Learn : How to enhance the education of computer science and informatics

The very nature of computer science with its constant changes forces those who wish to follow to adapt and react quickly. Large companies invest in being up to date in order to generate revenue and stay active on the market. Universities, on the other hand, need to imply same practices of staying up to date with industry needs in order to produce industry ready engineers. By interviewing former students, now engineers in the industry, and current university staff this thesis aims to learn if there is space for enhancing the education through different lecturing approaches and/or curriculum adaptation and development. In order to address these concerns a qualitative research has been conducted, focusing on data collection obtained through semi-structured live world interviews. The method used follows the seven stages of research interviewing introduced by Kvale and focuses on collecting and preparing relevant data for analysis. The collected data is transcribed, refined, and further on analyzed in the ���Findings and analysis��� chapter. The focus of analyzing was answering the three research questions; learning how higher education impacts a Computer Science and Informatics Engineers��� job, how to better undergo the transition from studies to working in the industry and how to develop a curriculum that helps support the previous two. Unaltered quoted extracts are presented and individually analyzed. To paint a better picture a theme-wise analysis is presented summing valuable themes that were repeated throughout the interviewing phase. The findings obtained imply that there are several factors directly influencing the quality of education. From the student side, it mostly concerns expectation and dedication involving studies, and from the university side it is commitment to the curriculum development process. Due to the time and resource limitations this research provides findings conducted on a narrowed scope, although it can serve as a great foundation for further development; possibly as a PhD research.
