This study aimed to validate the Patient Health Questionnaire (PHQ-8) in a sample of military personnel, through the analysis of psychometric properties, reliability, and confirmatory factorial analysis. The questionnaire consists of 8 items that allow the assessment of depressive symptoms. The sample included 127 Portuguese military personnel aged between 21 and 78 years old. The results revealed a good internal consistency (alpha=.90) and good adjustment indices (chi 2/df=1.332, GFI=.956, CFI=.988, RMSEA=.051, SRMR=.30). In addition, convergent validity also showed to be good and composite reliability was .873. Thus, the PHQ-8 reveals good psychometric properties, being recommended for use in clinical practice and research with Portuguese military.

Search Engine Optimization, or SEO for short, helps to improve the inbound user traffic of a website. Optimizing a website for search engines is now crucial to its success and ultimately to the company's ability to increase the business. Many companies websites on the Internet fail to use any SEO technique or strategy to improve their positioning in search engine results. Therefore, if other digital marketing strategies are not used to promote the website, its traffic will be very restricted. In this study several different SEO techniques were used to improve a website's overall indexing on the Google search engine. Through the implemented strategy it was possible to improve the positioning in search results of the company's website used in the case study, allowing several searches with different keywords to show the website on the first page of results. With the results obtained, it was possible to conclude that it is very important to find the perfect balance between SEO keyword competition and monthly search volume. To help select the best keywords for this particular website, the use of SEO tools are of the utmost importance.

Abstract
With the increasing use of air transport (cargo and passengers), the evolution of safety standards to an increasingly demanding level, markets have seen the development of business structures and strategies in the sector. Since 2009, revenues in the sector have been increasing, but it is necessary to optimize the operations that compose it. One of the critical areas is the management of maintenance schedules and consequently the stock management. In addition, the increase in e-commerce has led to cargoes having increasingly diverse specificity, value, and levels of urgency of delivery. The requirement for reliable and timely service is considered to be the main requirement and is matched by the price requirement. The high cost of stopping a plane outweighs the cost of transporting the required part, overriding the requirements of time and reliability, particularly in Aircraft on Ground (AOG) shipments. It has found that one of the problems is the small size of a large percentage of the components being transported. This feature encourages losses during transport and is blamed on various intermediaries in the supply chain. The need to track and trace product in real time is therefore crucial, particularly with the current demands of e-commerce customers. In this sense, the opportunity arose to the development of a package for the transport of small items allowing their traceability and monitoring. Through a questionnaire addressed to elements that intervene directly in the management of AOG shipments, 100% of respondents affirm that the use of an easy-to-identify box would avoid delays or losses and 91.7% of respondents affirm that a GPS device would improve the level of service.

Abstract
This research aims to analyze Corporate Social Responsibility (CSR) in the Sports Industry, specifically in the universe of sports clubs in Portugal. The main goal was to understand what the fans' perceptions on CSR practices of Portuguese sports clubs are, and how these perceptions influence their brand attitude and e-WOM intention. A questionnaire survey was conducted, obtaining a total of 159 responses. The research results show that the fans' perception of CSR initiatives positively influences their identification with the club, pride, word-ofmouth (WOM), electronic word-of-mouth (e-WOM) and the intention to remain members. The intention to become paid members of a sports club is not influenced by the fan's perception of CSR. However, their familiarity with the clubs' CSR initiatives positively influences their identification with the club, WOM and eWOM. In addition, relevant managerial implications are provided for sports club's managers as to how to improve CSR communication and create long-term benefits for the clubs.
