Mercado e desempenho operacional contábil de longo prazo

Following the value relevance literature, this study verifies whether the marketplace differentiates companies of high, medium, and low long-term operational performance, measured by accounting information on profitability, sales variation and indebtedness. The data comprises the Corporate Financial Statements disclosed during the period from 1996 to 2009 and stock prices of companies listed on the Sao Paulo Stock Exchange and Commodities and Futures Exchange - BM&FBOVESPA. The final sample is composed of 142 non-financial companies. Five year mobile windows were used, which resulted in ten five-year periods. After checking each company indices, the accounting variables were unified in an Index Performance Summary to synthesize the final performance for each five-year period, which allowed segregation in operational performance levels. Multiple regressions were performed using panel data techniques, fixed effects model and dummies variables, and then hypothesis tests were made. Regarding the explanatory power of each individual variable, the results show that not all behaviors are according to the research hypothesis and that the Brazilian stock market differentiates companies of high and low long-term operational performance. This distinction is not fully perceived between companies of high and medium operational performance.

Blood Pressure Measurement and Management Telemedicine System Based on a Smart-Phone

Variation of blood pressure throughout the day is one of the reasons why it is increasingly evident that the traditional way of measuring blood pressure in the clinic or office frequently produces numbers that grossly overestimate patientâ??s true blood pressure level. This is a major problem, since it is one of the most important and frequent measurements made by physicians. High blood pressure (BP) (hypertension) is a leading chronic condition in the globe and a major risk factor for severe diseases. Measuring the BP as accurately as possible can save a lot of human lives. However, the measurement and management platform can still be improved. In this paper, we describe a complete low-cost prototype system that we have developed for this purpose that can be part of and m-Health platform. Our BP telemedicine device is based on the oscillometric method for measuring BP. A microcontroller oversees measurement operations, to process acquired readings, and to calculate the heart-rate. A smart mobile phone commands the operation of our developed system via Bluetooth. A custom Windows Mobile application software was designed and developed to command the operation of this platform and to receive these vital measurements in a convenient manner. Obtained measurements can be stored on the mobile device to form a local database or transmitted via a designated wireless protocol.

An efficient and low cost Windows Mobile BSN monitoring system based on TinyOS

Monitoring methods for human body parameters are used over years to identify health conditions and biofeedback. For example, the core-body temperature is correlated with women fertility and ovulation periods. Mobile devices offer an extraordinary solution for health monitoring with mobility and continuous monitoring. This paper presents a Windows Mobile based system for body parameters monitoring. The proposed system comprises a SHIMMER-based body sensor network used to measure and collect body parameters, and a mobile application for personal monitoring. The communication between the sensor and the mobile device is performed over a Bluetooth connection. This system provides a low cost, reliable and robust mobile solution platform with full mobility support for active people that should be under continuous monitoring. The system was evaluated and validated, and it is ready for use.

Mechanism for Security Enhancement in Mobile Application Installation

Mobile operating systems (e.g., iOS, Android, Windows Mobile, etc) are becoming powerful platforms on which various applications can be installed and run. Each mobile OS offers application store (e.g., Apple App Store, Android Play, etc) for developers to easily publish applications and earn profits. However, existing mobile platforms provide little means for mobile users to evaluate risks on allowing certain security permissions when installing mobile applications. Since mobile users may not be able to justify the risks on allowing certain permissions required by an application, mobile users may install malware with extra permissions, which leads to security risk for mobile users, e.g., private information leaked, etc. In this paper, we present process and visual User Interface for mobile users to understand and justify the risks on permissions required by mobile applications during installation. We also present two algorithms for calculating the risks.

Acceptability and adoption of handheld computer data collection for public health research in China: a case study

BackgroundHandheld computers for data collection (HCDC) and management have become increasingly common in health research. However, current knowledge about the use of HCDC in health research in China is very limited. In this study, we administered a survey to a hard-to-reach population in China using HCDC and assessed the acceptability and adoption of HCDC in China.MethodsHandheld computers operating Windows Mobile and Questionnaire Development Studio (QDS) software (Nova Research Company) were used for this survey. Questions on tobacco use and susceptibility were drawn from the Global Adult Tobacco Survey (GATS) and other validated instruments, and these were programmed in Chinese characters by local staff. We conducted a half-day training session for survey supervisors and a three-day training session for 20 interviewers and 9 supervisors. After the training, all trainees completed a self-assessment of their skill level using HCDC. The main study was implemented in fall 2010 in 10 sites, with data managed centrally in Beijing. Study interviewers completed a post-survey evaluation questionnaire on the acceptability and utility of HCDC in survey research.ResultsTwenty-nine trainees completed post-training surveys, and 20 interviewers completed post-data collection questionnaires. After training, more than 90% felt confident about their ability to collect survey data using HCDC, to transfer study data from a handheld computer to a laptop, and to encrypt the survey data file. After data collection, 80% of the interviewers thought data collection and management were easy and 60% of staff felt confident they could solve problems they might encounter. Overall, after data collection, nearly 70% of interviewers reported that they would prefer to use handheld computers for future surveys. More than half (55%) felt the HCDC was a particularly useful data collection tool for studies conducted in China.ConclusionsWe successfully conducted a health-related survey using HCDC. Using handheld computers for data collection was a feasible, acceptable, and preferred method by Chinese interviewers. Despite minor technical issues that occurred during data collection, HCDC is a promising methodology to be used in survey-based research in China.

Security Model for Microsoft Based Mobile Sales Management Application in Private Cloud Computing

The Microsoft-based mobile sales management application is a sales force management application that currently running on Windows Mobile 6.5. It handles sales-related activity and cuts down the administrative task of sales representative. Then, Windows launch a new mobile operating system, Windows Phone and stop providing support to Windows Mobile. This has become an obstacle for Windows Mobile development. From time to time, Windows Mobile will be eliminated from the market due to no support provided by Microsoft. Besides that, Windows Mobile application cannot run on Windows Phone mobile operating system due to lack of compatibility. Therefore, applications those run on Windows Mobile need to find a solution addressing this problem. The rise of cloud computing technology in delivering software as a service becomes a solution. The Microsoft-based mobile sales management application delivers a service to run in a web browser, rather than limited by certain type of mobile that run the Windows Mobile operating system. However, there are some security issues need to concern in order to deliver the Microsoft-based mobile application as a service in private cloud computing. Therefore, security model is needed to answer the security issues in private cloud computing. This research is to propose a security model for the Microsoft-based mobile sales management application in private cloud computing. Lastly, a User Acceptance Test (UAT) is carried out to test the compatibility between proposed security model of Microsoft-based mobile sales management application in a private cloud and tablet computers.

Novel Packet Queuing Algorithm on Packet Delivery in Mobile Internet Protocol Version 6 Networks

New applications such as video conferencing and voice over IP present many challenges to the design of mobile networks. The mobile networks are constantly changing. The latest devices like smart phones, personal digital assistants, and mobile enabled laptops such as Windows Mobile and Windows Phone are truly able to deliver on any mobile broadband. As a July 2010 study by ERICSON, one of the top tier infrastructure suppliers for mobile networks shows, there are approximately five billions cell phone lines in the globe. This survey estimates 3.4 billion smart phone users in 2015. Thus, the Internet service providers must deliver a high quality of service to the customers. The key factor in quality of service is optimization for bandwidth allocation. Various queuing algorithms can be used in case of mobile IPv6 to control bandwidth allocation for instance. In this paper, we present various queuing disciplines in mobile IPv6 network when traffic class field in IPv6 is set to reserved, that is, the packets need quality of service throughout, from source to destination.

Damaged backup data recovery method for Windows mobile

Recent developments in grid and cloud computing technologies have enhanced the performance and scale of storage media. Data management and backup are becoming increasingly important in these environments. Backup systems constitute an important component of operating system security. However, it is difficult to recover backup data from an environment where the operating system does not work because the storage hardware has been damaged. This study analyzes the Volume Shadow Copy Service (VSS) used by the Windows operating system. Windows 8 has been implemented for mobile environments; hence, it could be used for data recovery from damaged mobile devices. VSS is a backup infrastructure provided by Windows that creates point-in-time copies of a volume (known as volume shadow copies). Windows Vista and later versions use this service instead of the restore point feature used in earlier versions of the operating system. The restore point feature logically copied and stored specified files, whereas VSS copies and stores only data that have changed in the volume. In a live system, volume shadow copies can be checked and recovered using built-in system commands. However, it is difficult to analyze the files stored in the volume shadow copies of a nonfunctioning system, such as a disk image, because only the changed data are stored. Therefore, this study analyzes the structure of Volume Shadow Copy (VSC) files that were logically stored. This analysis confirms the locations of the changed data and original copies by identifying a structure that stores the file data stream to file system metadata. On the basis of our research, we propose a practical application to develop tools for the recovery of snapshot data stored within the VSC files. We also present results of our successful performance test.

Decreasing workload among community health workers using interactive, structured, rich-media guidelines on smartphones

Currently, in developing countries, there is considerable interest in using mobile phones as job-aids for community health workers (CHWs) to improve the care they provide. However, acceptance of new technologies can be inhibited if the workload imposed is perceived as excessive compared to existing methods. To compare perceived workload of CHWs using clinical care guidelines presented on mobile phones versus using conventional paper-based guidelines. Validated clinical practice guidelines were developed as Interactive Structured Rich-Medical guidelines (ISRMGs) on Windows Mobile 6.5 mobile phones. A prospective randomized controlled study was performed in Colombia in which 50 CHWs used the ISRMGs, and paper-based materials with the same information, in a cross-over design to diagnose and treat 15 matched pairs of medical cases presented on Human Patient simulators. The NASA Task Load Index, a validated measure of perceived workload, was administered and results compared by means of a mixed model analysis. When using the ISRMGs on mobile phones the health workers reported statistically significant decreases in mental demand, frustration, and overall workload as compared to using paper-based job-aids. Use of ISRMGs on mobile phones by community health workers in developing countries has the potential to decrease their perceived workload, fatigue, and enhance their ability to provide better care for more patients.

Forensic access to Windows Mobile pim.vol and other Embedded Database (EDB) volumes

Forensic examination of Windows Mobile devices and devices running its successor Windows Phone 7 remains relevant for the digital forensic community. In these devices, the file pim.vol is a Microsoft Embedded Database (EDB) volume that contains information related to contacts, appointments, call history, speed-dial settings and tasks. Current literature shows that analysis of the pim.vol file is less than optimal. We succeeded in reverse-engineering significant parts of the EDB volume format and this article presents our current understanding of the format. In addition we provide a mapping from internal column identifiers to human readable application-level property names for the pim.vol database. We implemented a parser and compared our results to the traditional approach using an emulator and the API provided by the Windows CE operating system. We were able to recover additional databases, additional properties per record and unallocated records.

Windows Mobile LiveSD Forensics

More and more often, smartphones are relevant targets of civil and criminal investigations. Currently, there are several tools available to acquire forensic evidence from smartphones. Unfortunately, most of these tools require to connect the smartphone under investigation through a cable to an external device, like a computer or a multimeter. Some tools even require to disassemble the chips from the smartphone board.In this paper, we propose LiveSD Forensics, an on-device live data acquisition solution, to acquire evidence from both the Random-Access Memory (RAM) and the Electronically Erasable Programmable Read Only Memory (EEPROM) of Windows Mobile Devices.To the best of our knowledge, LiveSD Forensics is the only tool that performs on-device live data acquisition of the RAM and the EEPROM of Windows Mobile Devices. LiveSD Forensics uses a standard SD-Card equipped with tailored code to perform the data acquisition. Compared to other existing tools, LiveSD also generates the smallest memory alteration. Finally, to assess the effectiveness of the proposed methodology, we test LiveSD in a practical scenario, that is retrieving from the RAM the cryptographic key used by a known on-the-fly encryption tool. Results support the quality and effectiveness of our proposal.

Penetration Testing for Android Smartphones

One major challenge faced by Android users today is the security of the operating system especially during setup. The use of smartphones for communication, social networking, mobile banking and payment systems have all tripled and many have depended on it for their daily transactions.AndroidOS on smartphones is so popular today that it has beaten the most popular mobile operating systems, like RIM, iOS, Windows Mobile and even Symbian, which ruled the mobile market for more than a decade.This paper performspenetration testing of Android-based Smartphones using an application program designed to simplify port-scanning techniques for information gathering and vulnerability attack. In this paper, an attempt was made to test and analyze the security architecture of the Android operating system using the latest penetration testing and vulnerability tool based on Kali Linux. Three different Versions of Android, Version 2.3, 3.2 and 4.2 were simulated on a virtual machine. The result shows that although there is an improvement in the security stack of the different AndroidVersions but Version 4.2 is more secured than the others. This work is important for users and researchers who use their Android smartphones in a critical environment with hostile network traffic.

Field identification of habitats directive Annex I habitats as a major European biodiversity indicator

Annex I of the EU Habitats Directive lists the habitats which must be protected by the designation and management of protected areas in the European Union. These habitats are therefore a key indicator of biodiversity and although organised into nine groups, there is no way to identify them other than by gaining familiarity with the list. It is therefore necessary for observers who do not have sufficient experience to have a system to guide them into an appropriate class when in the field. A key has therefore been produced based on defined habitat categories that can be recorded consistently in the field in order to restrict the range of options for any given habitat patch. Expert judgement may still be needed to finalise the allocation to a specific class.A direct key is not possible because the list of Annex I habitats has been produced by meetings of national experts and final allocation often requires scientific judgement. A rule based system for Annex I habitats has therefore been designed to aid identification of the classes and to promote consistent interpretation between Member States. It is intended that in due course that the descriptions will be further developed from other data sources and by consultation with local experts.The first stage is to record a defined list of habitat categories in the field according to a series of rules. In the second stage a structure is provided to identify Annex I habitats that are landscape units or habitat complexes. In the third stage the recorded habitat categories are used to provide a structure to identify other classes using moisture and acidity levels as the primary filter. All Annex I habitats are characterised by summary data, including indicator species and geographical distribution. The system has been tested in the field throughout Europe and is available for field computers under Windows Mobile in order to enable ready access and encourage consistency.

Digital wars: Apple, Google, Microsoft and the battle for the Internet

Which of Apple, Google and Microsoft had an office with a drawer of broken dreams ---and what (real) objects lay inside it?When did Microsoft have the chance to catch Google in making money from search ---and who vetoed it?Why did Google test 40 shades of blue on its users?How long did outside developers wait before asking to write apps for Apple's iPhone after Steve Jobs announced it?Who said that Microsoft should have its own music player -- and why did it fail?Digital Wars starts in 1998, when the internet and computing business was about to be upended -- by an antitrust case, a tiny startup and a former giant rebuilding itself. Arthur looks at what are now the three best-known tech companies and through the voices of former and current staff examines their different strategies to try to win the battle to control the exploding network connecting the world. Microsoft was a giant -- soon to become the highest-valued company in the world, while Apple was a minnow and Google just a startup. By February 10 2012, Apple was worth more ($462bn) than both Microsoft ($258bn) and Google ($198bn) combined.The chance had come from tumultuous battles between the three. To win their battles: Apple used design, the vertical model of controlling the hardware and software and a relentless focus on the customer to the exclusion of others.Microsoft depended on the high quality of its employees' programming skills and its monopolies in software to try to move into new markets - such as search and music.Google focused on being quick, efficient and using the power of data analysis - not human taste - to make decisions and get ahead of would-be rivals. With exclusive information from interviews with current and former employees of the three companies Arthur also addresses:- What the inventors of the hard drive used in the iPod thought it would really be used for- How Apple transformed the smartphone market- Which of Android or Apple forced Microsoft to abandon Windows Mobile- What happened to Microsoft's tablet plans

A new mobile application for maintenance tasks in photovoltaic installations by using GPS data

The application of the Information and Communication Technologies (ICTs) to the photovoltaic (PV) energy sector has increased notably in the last years. This paper presents a new mobile software application for maintenance tasks in PV installations by determining the PV output power of the system, the daily energy production, the clear-sky global solar radiation and other parameters associated with solar position from Global Position Data in handheld devices endowed with Android or Windows Mobile operating systems. The calculation of these parameters permits a technician to know if the PV plant is working properly, since the difference between the PV output power supplied by the installation in a clear-sky day for a determined hourly period and the values estimated by the application should be minimal. In case of fixed installations, the application also permits to determine if the PV module support structures of the installation are correctly oriented. Some comparisons between data supplied by four real PV installations and data calculated by the proposed application were performed for evaluation purposes.
