Knowledge partnerships with equipment suppliers

Background: Knowledge partnerships are conducted based on a model of knowledge creation and management. SECI model, created by Nonaka and Toyama, helps firms to deal with the creation of new knowledge and helps in the transition between tacit and explicit knowledge (Nonaka, Toyama & Konno, 2000). Purpose: The main aim of this work is for Sonae MC to be able to differentiate regarding its suppliers by being able to create knowledge partnerships. Methods: The methodology used in this study starts with an analysis of the type of equipment demanded and which suppliers are the biggest, more flexible and more willing to cooperate. Then, after interviewing the suppliers, we are able to list the knowledge that they are looking for and create a possible knowledge management model, where both parts get involved. Results: What the suppliers are looking for can be integrated on the knowledge creation spiral of Sonae MC. However, it has not been done until now due to confidentiality issues and the immense number of available competing suppliers that Sonae benefits from. Conclusion: Throughout this analysis it can be seen that there is room to cooperate with the suppliers and to improve their services by involving them in the decision planning operations and by giving them access to non-public information.Título: Parcerias de Conhecimento com Fornecedores de Equipamento Introdução: Parcerias de conhecimento são criadas com base num modelo de criação e gestão de conhecimento. SECI Model foi criado por Nonaka e por Toyama, com o objetivo de funcionar como uma ferramenta de apoio em lidar com a criação de novo conhecimento e ajudar na transição entre o conhecimento tácito e explícito (Nonaka, Toyama & Konno, 2000). Objetivo: O principal objetivo deste trabalho é de permitir à Sonae MC diferenciar em relação aos seus fornecedores através da criação de parcerias de conhecimento. Métodos: A metodologia utilizada neste estudo começou com um estudo do tipo de equipamento que é procurado pela Sonae MC e identificar quais os fornecedores mais relevantes, mais flexíveis e com maior vontade de cooperar. Seguiu-se de entrevistas, onde se listou o tipo de conhecimento que estes estão à procura culminando assim na criação de um possível modelo de gestão de conhecimento, com o envolvimento de ambos. Resultados: O conhecimento que os fornecedores estão à procura pode ser integrado na espiral de criação de conhecimento da Sonae MC. No entanto, tal não foi feito até agora devido a problemas de confidencialidade e devido aos benefícios que a Sonae MCV tem em lidar com fornecedores latamente competitivos. Conclusão: Ao longo desta análise podemos ver que há espaço para uma cooperação com os fornecedores, seja envolvendo-os na formulação do plano das atividades anuais ou dando-lhes acesso a informações não-publicas

Perceived image of Portugal by swedish tourists

Mestrado em MarketingO turismo desempenha um papel importante na economia Portuguesa. Todos os esforços para aumentar o número de turistas que chegam a Portugal tem sido reconhecidos em todo o mundo através de prémios e ocupar o primeiro lugar das melhores cidades europeias a visitar. No entanto, a imagem de Portugal não tem muito impacto sobre certos países, como a Suécia. Imagem do destino turístico é um assunto muito importante e discutido na literatura turismo. O objetivo deste estudo é compreender os atributos que os suecos consideram na escolha do destino turístico, perceber também a imagem percecionada de Portugal para consequentemente sugerir estratégias para aumentar a comunicação de Portugal na Suécia. Depois de fazer uma breve revisão da literatura, o modelo seguido foi o Echtner & Ritchie (1993), modelo Tridimensional, que inclui os atributos funcionais (tangíveis) e os atributos psicológicos (intangíveis) que permitem ter uma análise completa da imagem percebida de Portugal. Os resultados mostram que os turistas suecos procuram um destino agradável para se divertirem, conhecer a cultura e a história e, principalmente, tem em consideração o clima do destino turístico. A imagem percebida de Portugal é positiva na maioria dos atributos tangíveis e intangíveis avaliados. Finalmente, a comunicação deve ser feita na Internet através de campanhas em jornais e revistas online, através das redes sociais e blogs.Tourism plays an important role in the Portuguese economy. All efforts to increase the number of tourists arriving in Portugal has been recognized worldwide by awards and Lisbon occupies the first place on the rank of the best European cities to visit. However, the image of Portugal does not have that much of an impact on certain countries, such as Sweden. The image of tourist destination is a very important topic discussed in tourism literature. The aim of this study is to understand the attributes that Swedish people consider while choosing their destination, to find out the perceived image of Portugal and, therefore, suggest strategies to increase the communication of Portugal in Sweden. After making a brief literature review, the model followed was the Echtner & Ritchie (1993), Tri-dimensional model, which includes the functional attributes (tangible) and psychological attributes (intangible) that allows to have a complete analysis of the perceived image of Portugal. The results showed that the Swedish tourists look for in a destination to have a good time, get to know the culture and history and specially they take into account the weather of the destination. The perceived image of Portugal is positive in most of the tangible and intangible attributes evaluated. Finally, the communication should be done over internet through campaigns on magazines and newspapers, using social media and blogs

Indoor air quality for sustainability, occupational health and classroom environments through the application of earth plaster

[EN] Clearly, the construction sector makes a large scale contribution to environmental degradation and urgently needs to change its principles to focus on environmentally sustainable construction. Earth, as a building material, has a potential cradle to cradle life cycle, thus, achieving a circular economy. This material also displays numerous advantages, namely: economic and ecological and as well as the ease of reuse and recyclability. The earth material also registers a high capacity to absorb and release water vapor, which helps to balance the relative humidity and the internal temperature, promoting not only the comfort of occupants but also the quality of the air in buildings. The materials applied in construction hold great influence over the indoor air quality (IAQ). IAQ ranks as such a crucial issue that it appears in the seventeen 2030 Agenda SDGs. As about 90% of our time is spent inside buildings, whether for leisure or work, it is essential to live in spaces with adequate and healthy interior environments. According to the World Health Organization, good air quality represents a basic requirement for life and is a determining factor for the health and well-being of occupants of indoor spaces. In schools, and due to the complex and diversified activities developed there, in addition to adverse health effects, indoor air quality may also have a direct impact on student concentration and performance. Understanding and studying materials, specifically earth mortars, with the ability to capture pollutants and reduce their concentration while helping to regulate the temperature and relative humidity conditions, and student comfort, is thus extremely important. Hence, with the objective of improving the development of construction strategies, this article details and highlights the beginning of the RESpira project.The authors acknowledge the Instituto Politécnico de Lisboa under the auspices of project IPL/2021/RESpira_ISEL.

Aplicação de análise térmica (DSC) na identificação e caracterização de materiais têxteis

A identificação de fibras é uma necessidade constante quer a nível de investigação quer industrial e é feita através de um conjunto de ensaios que implicam grande consumo de tempo e recursos e que incluem tais como a observação microscópica, comportamento ao calor e à chama, ponto de fusão, solubilidade, testes de coloração, índice de refração e massa volúmica. O presente trabalho pretende analisar a utilização da calorimetria diferencial de varrimento (DSC) na identificação e caracterização de fibras têxteis. As características dos materiais que podem ser identificadas usando análises térmicas, incluem a temperatura de transição vítrea; cristalinidade; temperatura de fusão; temperatura de cristalização a frio; processos térmicos associados à libertação de água e degradação térmica [1,2,3]. Neste trabalho, serão apresentados vários casos práticos, sobre a aplicação desta técnica analítica nas fibras naturais e sintéticas. Um dos estudos realizados refere-se à identificação de fibras naturais, como o algodão e sintéticas, como a poliamida. É também descrita a caracterização de polímeros modificados, em que um dos exemplos se refere à caracterização do poli (álcool de vinilo) (PVA) modificado por indução fotoquímica na presença de um iniciador (Fig 1).This work is also funded by FEDER funds through the Competivity Factors Operational Programme - COMPETE and by national funds through FCT – Foundation for Science and Technology within the scope of the project POCI-01-0145-FEDER-00713

Storytelling as Media Literacy and Intercultural Dialogue in Post‐Colonial Societies

UIDB/05021/2020 UIDP/05021/2020This article reflects upon digital storytelling and collaborative media practices as valuable tools for reassessing memory, questioning identity discourses, and unveiling the cultural diversity of contemporary societies. The digital age allows for a constant re‐reading and re‐mediation of cultural archives by ordinary citizens, namely by younger generations, and for the production and dissemination of alternative narratives about the present. These are crucial opportunities for post‐colonial societies to overcome silences around difficult memories that hinder a collective reappropriation of the past, confront some of the current issues on ethnical diversity, and discrimination and reimagine a more inclusive identity. However, taking advantage of this opportunity implies fully recognizing the role of media technology in shaping memory, social individuation and establishing networks, making media literacy and media education crucial aspects of cultural dialogue. Based on the experience of a citizenship project about the post‐colonial condition and Afro‐European interculturality, this essay reflects on digital storytelling, and co‐creative practices as relevant literacy and education strategies for furthering interculturality in contemporary societies.publishersversionpublishe

Social marketing through communication campaigns: the APAV case

Social responsability is gaining its momentum in the formulation of the strategy of the organizations, at the organizational, behavioral and communicational level, and for many organizations it is even considered a key differentiator and a proximity element to customers, whom are increasingly sensitive to individual and collective well-being (Carrol & Shabanna, 2010). Yet, welfare is not the prerogative only of companies, but also of non-profit organizations, which include it on their activity as a goal in itself. And for many of these, social causes are the main reason for their existence. This research focuses on one of these non-profit organizations - APAV - whose mission is the prevention, the combat and the protection of victims of domestic violence. Our object of study is one its recent mass media campaigns, that aim to alert and modify the behavior of the various actors involved in the process (victims, witnesses, society in general). A quantitative research has been conducted, operated by the application of questionnaire surveys to a sample of 134 subjects that seeks to assess to extent to which the emotions elicited by watching an APAV campaign influence behavior towards domestic violence, considering the mediating role of attitudes and subjective norms. The results measured by means of Structural Equation Modeling (SEM), show the validation of only two working hypotheses under study, indicating that the attitude towards advertising has a positive effect on attitudes towards domestic violence influencing in turn, behavioral intention of subjects. The main social and academic contributions of this research are discussed.N/

Looking beneath the surface: how brands led to consumer engagement in social media

It is undeniable that the strong growth of social media and content generated in them is presented as a rising tide that came to stay! We are facing a change of structural nature, requiring brands to understand that shift and to adapt their strategies as they start looking at consumers as active partners, developing with them a close relationship, collaborative, deeply relational, reinforcing and strengthening the bond and an emotional connection. This fact led to an explosion of interest in consumer engagement. The opportunities presented by social media to help build close relationships with consumers seem to have attracted the increasing interest of practitioners in a wide variety of industries worldwide. Academic scholarship consumer engagement, however, has lagged practice and its theoretical foundation is relatively underdeveloped and a better understanding of the concept and their drivers is essential to develop accurate strategies. This paper seeks to address some of these issues. From the universe of brands, two popular fashion brands (Cubanas and Paez) were selected, based on RankUPT [1], a statistics website aimed at the analysis of Facebook’s activity in Portugal that makes a daily measurement of homepages, based on the number of fans. A qualitative netnographic study was conducted, through a non-interventionist observational technique, added with a collection of qualitative behavioral data which took place between March and December 2015, and also considering the use of secondary data for the descriptive analysis of the brands in question. Metrics used for measuring engagement were the most commonly used in other studies (e.g., likes, sharing, commenting), along with the de Vries, Gensler and Leeflang [2], Cvijiki and Michaheles [3], and Malhotra, Malhotra and See [4], criteria for the drivers of engagement. The results are discussed and the academic and business implications of the study are examined, in particular for branding and relationship marketing.info:eu-repo/semantics/publishedVersio
