Background: The number of older adult Internet users has been rising worldwide. Information and communication technology, namely the internet, has been recognized to provide a great potential and new opportunities to society as a whole, and to active aging in particular. Objective: The aim of this paper was to conduct a systematic literature review to determine the empirical literature produced since 2005 about the internet use applied to active aging. Method: Throughout the application of a serious of inclusion and exclusion criteria, 30 papers were identified and analyzed of 646 potentially relevant ones. Results: The study provides a comprehensive review of the main subject areas that research has focused, concerning the use of internet to promote active aging. Conclusions: Although scarce, research directly suggests internet as an important promoter of social participation, health, attitude change and education for the elderly, and is differentiated according to different profiles of elder users.

Social Media is a subject that is being very discussed in the present. The increasing availability of internet and the growth of Social Media platforms drove organizations attention to Opinion Mining and Sentiment Analysis. One of the most popular Social Media Platform is Facebook. In this Social Media Platform users/consumers can express their feelings with comments or with emotion buttons. With the functionalities of Facebook, they can criticize, praise, suggest or expect. The user's interactions with a brand page as posts, likes, shares or comments are getting more relevance in present days. The analysed data can give to decision-makers new approaches to run their business, understand their brand value against the competitors or even understand better what are the evaluations of customers or potential customers about the brand products or services. The purpose of this paper is to explain how to extract and prepare data collected in Facebook using open-source tools to perform a Sentiment Analysis.

The Integrated Reporting — IR acquires more relevance as a tool for the investor decision about the companies sustainability. An Integrated Reporting provides information concerning risk evaluation and potential future value growth. Therefore, influencing risk management and audit, leading to the need for new assurance frameworks to assure the compliance of integrated information. The motivation of this research is at the level of assurance on Integrated Reporting. The research objective is to analyze the types of assurance provided on Integrated Reporting. The methodological approach undertakes a qualitative study on the assurance provided on Integrated Reporting. The empirical analysis develops a study of integrated reports related to 46 organizations. The obtained results indicate that more than half of the analyzed companies provide, in a voluntary basis, independent assurance, among others. The contribution of the paper is a better knowledge of the practices of assurance on Integrated Reporting and on Non-Financial information, that could lead to better decisions and analysis on this subject for academics, practioners, auditors and regulators.

The participatory design process aims to ensure that a product or service under development achieve the needs and expectations of its target population. This process promotes highest levels of accessibility, acceptance and use of the developed solutions. This is even more relevant when the target audience is the elderly. Interactive television applications can resolve some constrains that seniors feel when accessing informational content. So, this paper reports the field work of data collection and analysis, that aim to define the best way to interrupt the television broadcast in an iTV platform addressed to Portuguese seniors. To this end, participatory design sessions were organized in a focus group format where participants' preferences were collected. In this way, the preference fell to the imposed view, and these results must be confirmed at the time of the tests in real context.

Social networking websites are increasingly used as tools to communicate between people, whether these consumers or companies. Facebook is one of the most users platforms in the world and is also highly valued as a communication tool by companies. In this field, the present research establishes several factors of interest to contemplate in the creation of a communication strategy in Facebook, focusing mainly on the coffee and pastry sector. The main results indicate that the determining factors that contribute to a good communication strategy are, in particular, the attention to detail of the shared contents and the care in maintaining close communication with the client, not forgetting the regular sharing of contents. The results obtained allow us to present some communication proposals, in a publication format, for the brands under study.

The main goal of this research is to check how the audit of the individual financial accounts of unlisted national companies is associated with the level of Book-Tax Differences, calculated by the difference between the reported book value and the corresponding tax returns. The empirical study was based on 236,950 observations from 2010 to 2013. The accounting data were taken from the data base Bureau van Dijk's Amadeus. The results obtained allow us to conclude that the companies whose accounts are audited show greater differences between the accounting result and the tax result, particularly those that are audited by one of the four largest professional services networks in the world (EY, PwC, Deloitte and KPMG).
本研究的主要目的是检查非上市国家公司的个人财务账户审计如何与账面税收差异水平相关联，通过报告的账面价值与相应的纳税申报表之间的差异来计算。该实证研究基于2010年至2013年的236950个观测数据。会计数据来自于Bureau van Dijk’s Amadeus数据库。所获得的结果使我们能够得出结论，审计账目的公司在会计结果和税务结果之间表现出更大的差异，特别是那些由世界上四大专业服务网络之一(安永，普华永道，德勤和毕马威)审计的公司。

Nowadays there is an increasing interest in mobile application development. However, developers often disregard, or at least significantly adapt, existing software development processes to suit their purpose, given the existing specific constraints. Such adjustments can introduce variations and new trends in existing processes that in many occasions are not shared with the scientific community since there is no official documentation, thus justifying further research. In this paper, we present a study and characterization of current mobile application development processes based on a practical experience. We consider a set of real case studies to investigate the current development processes for mobile applications used by software development companies, as well as by independent developers. The result of the present study is the identification of mobile software development processes, namely agile approaches, and also of shortcomings in current methodologies applied in industry and academy, namely the lack of informed and experienced resources to develop mobile apps.

Vision is one of the most important senses that helps people interact with the real world. Commonly visually impaired develop their other senses to feel their surroundings, but in certain cases, this is not enough. The senses can be disturbed by noise or illness. For this reason, many artifacts have been developed to help this group of people. Artifacts such as white canes or guide dogs help sightless to move around in their surroundings. This article proposes the use of a system that detects and recognizes nearby obstacles, giving an audible warning in order to avoid a collision. The prototype is wireless with the purpose to be comfortable for the user. The system helps sightless to move around in indoor or outdoor environments. The objectives of the system are to detect obstacles that white canes or guide dogs cannot, expanding their range of detection.
