The impact of telecommuting on the performance and productivity of teleworkers
Get PDFFerreira, Ana Cristina, e outros (2023) - International conference on technology management and operations. - Lisboa : Universidade Lusíada Editora. - ISBN 978-898-640-273-0The pandemic phenomenon Covid 19 has significantly conditioned the routines of workers in their companies. There was a need for organizations to adapt to a new context, quickly and efficiently, using telework. This study aimed to analyse the impact of telework on teleworkers’ productivity. In this methodology a sample of 152 professionals was used and a survey was administered through an online questionnaire. The respondents expressed, in a positive way, a quick and easy adaptation to telework, with a greater conciliation between profession al and family life, decrease in business expenses, positive environmental impact, resulting from the reduction of travel to work and a reduction of costs for companies. They also consider that they were able to increase productivity and performance because they had fewer distractions and were not bothered as often as if they were physically in the company. On the other hand, they consider as a disadvantage the fact that not all workers can carry out their activity becauethey don’t have Internet or are from the industry/production areas, which are indispensable in face-to-face work. Despite adaptability, with regard to how they would like to work in the future, respondents prefer hybrid work to remote/presence work
Management of hospital resources and hospitalization in EU27 : a factor analysis
Get PDFFerreira, Ana Cristina, e outros (2023) - International conference on technology management and operations. - Lisboa : Universidade Lusíada Editora. - ISBN 978-898-640-273-0.The article aims to corroborate whether, in terms of public health and regional imbalances in the European Union for the year 2019, there is a correlation between the degree of wealth of a country and the way in which public health is managed and, likewise, to find independent factors that can group the various variables and explain them. Data from the 27 countries of the European Union were extracted from Eurostat, of which only 16 were subject to analysis, seeking to prevent conspicuous overestimation by missing data. Through the application of a data reduction methodology, Factor Analysis, seven variables were transformed into two factors: Hospitalization (Infant mortality, Hospital days of in-patients, and Live births) and Hospital Resource Management (Discharges, Hospital beds, GDP per capita, and Preventable and treatable mortality). Thus, it was found that the average number of days in hospital in countries with high GDP is equal to the average number of days in hospital in countries with low GDP (where GDP can represent the management of hospital resources and days in hospital are a proxy of the hospitalization). Proven by the factors, it was found, therefore, that the hospitalization is not significantly different, in the different levels of management of hospital resources in the countries, with Germany standing out as an outlier by boasting a greater number of births, more days in the hospital and a larger number of beds. It is also inferred that this scenario would be projected for the other eleven countries not considered in the Factor Analysis

Shift scheduling with linear programming : a case study in a fire station
Get PDFFerreira, Ana Cristina, e outros (2023) - International conference on technology management and operations. - Lisboa : Universidade Lusíada Editora. - ISBN 978-898-640-273-0.Due to demographic variations and climate changes, the risks of natural disasters are increasing. Therefore, with the risk of fire and other public welfare risks, firefighters are necessary to protect people in a community and its assets, responding to emergencies, quickly and effectively. This way, it is necessary to have a sufficient number of firefighters in a fire station, to give a reliable answer to any emergency that could occur. However, human and economic resources are scarce. In this paper, a linear programming approach was developed in order to determine the best shifts of the working week, minimizing the number of firefighters necessary to satisfy the already registered and emergency tasks. The results show that, with the solution obtained, there is a slack between the solution found and the reality applied in the fire station, hich could be improved by changing their shifts and reducing the number of firefighters for each shift
A cultura organizacional e resultados financeiros
Get PDFMestrado em GestãoExame Público realizado em 11 de abril de 2024Falando em cultura Organizacional e Resultados Financeiros, identifica-se um problema de investigação: pode influenciar a Cultura Organizacional na obtenção de bons resultados organizacionais, isto é, bens financeiros, clima organizacional, entre outros, e se pode de que forma.
Para tal é necessário perceber como o comportamento organizacional depende da Cultura organizacional. Em teorias de cultura organizacional o mais destacado é o Schain, o seu estudo, é interessante porque descreve um modelo base de pressupostos que dirigem a organização (artefactos visíveis - crenças, valores, identidade de cada um; valores compartilhados - razões do comportamento; pressupostos básicos - perceber, pensar, sentir) que ajudam no processo de aprendizagem e no processo de resolução dos problemas. Outras teorias, modelos estudados confirmam que Schain está certo no seus pressupostos. A sua teoria serviu de base para muitas outras teorias posteriores. Por outra parte, se estudou a vertente Financeira da organização, por ser o objetivo de toda organização, manter a estabilidade e funcionamento ou evoluir nos seus
resultados financeiros. Por este motivo, fez-se um estudo de caso na empresa angolana “Talulenga Lda”, e na empresa Cante Portuguesa. Estudando a cultura organizacional ajudou muito a entender como se origina uma cultura organizacional e como fortalecê-la, para melhorar o comportamento organizacional dos funcionários. Entendeu-se deste modo quais são os valores que se posicionaram na mente dos fundadores e na mente dos stakeholders. Estudou-se também a : Google, Coca-Cola, Netflix, Facebook e a Apple, por terem cultura organizacional forte. Em suma, fez-se um estudo empírico para testar a validade de teorias e hipóteses, optouse por um estudo misto, método qualitativo ( entrevistas e grupo focal) e método quantitativo (inquéritos - Google form e analisados pelo SPSS). Desta feita, chegou-se à conclusão de que para se originar bons resultados a nível organizacional os funcionários têm que adotar comportamentos e atitudes que promovam tal coisa, uma vez que a Cultura organizacional é a força mais fluente na organização. A melhor estratégia para tal é gerir e fortalecer a Cultura organizacional para melhorar e qualificar o comportamento dos funcionários e suas atitudes.
Palavras-chaves: Cultura, Organização, Gestão dos recursos humanos, Ambiente organizacional, Recursos, Finanças, lucro, benefício, orçamento, proveito.Speaking about Organizational Culture and Financial Results, a research problem is identified: how Organizational Culture influences the achievement of good organizational results, that is, financial assets, organizational climate, among others. To do this, it is necessary to understand how organizational behavior depends on organizational Culture. In theories of organizational culture, the most prominent is Schain, his study is interesting because it describes a base model of assumptions that guide the organization (visible artifacts - beliefs, values, identity of each person; shared values - reasons for behavior; assumptions basics - perceiving, thinking, feeling) that help in the learning process and in the problem-solving process. Other theories and models studied confirm that Schahin is right in his assumptions. His theory served as the basis for many other later theories. On the other hand, the financial aspect of the organization was studied, as it is the objective of every organization, to maintain stability and functioning or to improve its financial results. For this reason, a case study was carried out in the Angolan company “Talulenga Lda”, and in the Portuguese company Cante. Studying organizational culture helped a lot to understand how an organizational culture originates and how to strengthen it, to improve the organizational behavior of employees. In this way, it was understood which values were positioned in the minds of the founders and in the minds of the stakeholders. Google, CocaCola, Netflix, Facebook and Apple were also studied, as they have a strong organizational culture. In short, an empirical study was carried out to test the validity of theories and hypotheses, a mixed study was chosen, qualitative method (interviews and focus group) and quantitative method (surveys - Google form and analyzed by SPSS). This time, it was concluded that in order to generate good results at an organizational level, employees have to adopt behaviors and attitudes that promote this, since Organizational Culture is the most fluent force in the organization. The best strategy for this is to manage and strengthen organizational culture to improve and qualify employee behavior and attitudes.

An adapted analytic hierarchy process for the supplier selection : model validation for a textile industry application
Get PDFFerreira, Ana Cristina, e outros (2023) - International conference on technology management and operations. - Lisboa : Universidade Lusíada Editora. - ISBN 978-898-640-273-0.Nowadays, it becomes increasingly important to efficiently manage business resources so that companies become more competitive in the market. Bearing in mind the current crisis (e.g., lack of components, economic constraints), it has become increasingly difficult to make a cautious selection of suppliers for the industrial context. The paradigm for suppliers’ selection and evaluation has been changing and may include different criteria, which is difficult to compare without a decision support system. Price is no longer the companies’ exclusive main concern given the difficulty in accessing raw materials or components. Environmental sustainability criteria have been introduced as a relevant factor to consider when choosing a new supplier. The delivery time, the quality of the materials, the flexibility, the capacity of response and the costs associated with he logistics have become criteria with greater weight in the final decision. Faced with this diversity of criteria, companies increasingly need to have systems that can help in their decision-making process. In this work, it is proposed an adapted analytic hierarchy process model for supplier selection, applied in a textile company. According to the diversity of criteria, a multi-criteria decision support model was implemented that considers both quantitative and qualitative criteria. The model is adapted from an analytic hierarchy process and assigns a weighting to each supplier, considering the different criteria. This algorithm was developed in Python. The final output is made available through a ranking system. At the end of the process, the decision maker can select the most promising supplier (supplier A with a weight of 29.3%) for the defined criteria, allowing a more informed decision by the company
Intuitionistic fuzzy X- R control chart based on IF-WABL defuzzification method
Get PDFFerreira, Ana Cristina, e outros (2023) - International conference on technology management and operations. - Lisboa : Universidade Lusíada Editora. - ISBN 978-898-640-273-0.Control charts are one of the most important tools used for process monitoring. Traditional control charts use crisp data, but in the real world the processes to be monitored have uncertainties, due to human subjectivity, measurement instruments among other factors. In this case Shewhart charts may not be adequate and fuzzy control charts should be used. In this paper X-R fuzzy control chart for triangular intuitionistic fuzzy numbers (TIFNs) using Intuitionistic Fuzzy - Weighted Averaging Based on Levels (IFWABL) defuzzification method is proposed. An interesting aspect in the defuzzification method that is considered, which differs from others, is the property of flexibility. The method is considered flexible because users can adjust the coefficients according to the problem being solved. Therefore, it is possible to obtain different defuzzification values for the same triangular intuitionistic fuzzy number. This is completely in accordance with the principles of fuzzy set theory. Intuitionistic fuzzy control charts are able to represent both uncertainty and hesitation present at various stages of the process. An illustrative example is developed in order to understand and show the use of the proposed control chart and finally the results are interpreted
A importância do controlo financeiro na gestão [Documento electrónico] : estudo empírico nas micro e pequenas empresas brasileiras
No full textDissertação de mestrado em GestãoExame público realizado a 8 de fevereiro de 2023, 11hO controlo de gestão auxilia na melhoria da eficiência e eficácia operacional por meio de instrumentos e técnicas de gestão. Ela permite um maior controle sobre as atividades da empresa, identificando oportunidades de melhorias e contribuindo para uma gestão mais eficiente dos recursos disponíveis.
O presente trabalho procura analisar a existência do controlo de gestão nas micro e pequenas empresas brasileiras, para destacar a importância da gestão por meio das práticas do controlo nestas empresas.
Para alcançar os objetivos definidos nesta dissertação utiliza-se uma amostra constituída por 83 inquiridos e uma metodologia quantitativa.
Apesar de existirem estudos sobre o assunto, as pesquisas na área são relativamente antigas, o que destaca a importância de atualizar o conhecimento. Como dominam no cenário econômico brasileiro micro e pequenas empresas, compreender suas práticas de controladoria torna-se crucial para a saúde financeira do país. Esta pesquisa visa preencher essa lacuna, fornecendo perceções valiosos sobre o papel da controladoria nesse contexto empresarial, visando influenciar positivamente a economia brasileira, tornando essa investigação relevante.
Conclui-se que as pequenas e micro empresas enfrentam dificuldades em aplicar eficazmente a controladoria em suas operações. Embora afirmem possuir sistemas de informação para projeções se utilizarem a contabilidade para necessidades gerenciais e fiscais, não demonstram uma integração completa da controladoria. Enquanto usam atividades de controlo operacional, como contas a pagar, contas a receber e controle de stocks, deixam de utilizar análises de rácios financeiros, que são essenciais para o controle de gestão.Management control helps to improve operational efficiency and effectiveness by means of management tools and techniques. It allows greater control over the company's activities, identifying opportunities for improvement and contributing to more efficient management of available resources. The present study sought to analyse the existence of managerial control in Brazilian micro and small companies, with the objective of evidencing the importance of management through managerial control practices at those companies, with the purpose of investigating whether organizations in these dimensions are using managerial control instruments as support in the management of their companies. To achieve the objective, three questions on the theme were defined and two hypotheses were tested. The questions and the hypotheses were answered and tested using a sample of 83 respondents and a quantitative methodology. Although there are studies on the subject, research in the area is relatively old, which highlights the importance of updating knowledge. As these companies dominate the Brazilian economic scenario, understanding their controlling practices becomes crucial for the country's financial health. This research aims to fill this gap, providing valuable insights into the role of controllership in this business context, aiming to positively influence the Brazilian economy, making this investigation relevant. After the consolidation of the results, it is concluded that small and micro-enterprises face difficulties in effectively applying controllership in their operations. Although they claim to have information systems for projections and use accounting for managerial and fiscal needs, when confronted with the instruments of the management process, they do not demonstrate a complete integration of controllership. While they use operational control activities, such as accounts payable, accounts receivable and inventory control, they fail to use financial ratio analysis, which are essential for management control
A alienação parental
No full textDissertação de mestrado em Direito, área Jurídico-CivilísticasExame público realizado em 27 de fevereiro de 2024, às 18h30A Alienação Parental surge no enquadramento de um divórcio ou separação em que um dos progenitores, usando da sua posição de superioridade e de dependência do filho menor, demonstra uma conduta que, ativa ou passivamente, incita ao afastamento do menor em relação ao outro progenitor. O intuito é sempre o de fomentar o afastamento do menor face a um dos progenitores, no entanto, há que ressalvar a possibilidade de a Alienação Parental ser praticada por pessoa próxima ao menor, que não um progenitor, como é o caso de um avô.
Optou-se, no presente trabalho, por seguir uma metodologia de pesquisa exploratória, descritiva e explicativa. Exploratória, porque se procede à pesquisa de informações e formulação de questões sobre um problema em específico - a Alienação Parental; descritiva, no sentido de analisar a Alienação Parental e respetivas caraterísticas; e explicativa, analisando e interpretando o problema, apontando as suas causas, consequências e possíveis soluções, especificamente no nosso país.
Num Mundo em que os relacionamentos são, cada vez mais, fugazes e substituíveis, em que, facilmente, se rompem matrimónios e se separam famílias, a Alienação Parental vê um “solo fértil”, onde poderá expandir-se e crescer, tal como o faz uma qualquer planta. Mas, lá está, carecendo de tratamento no ordenamento jurídico português, a Alienação Parental é um problema grave a que deve ser dada uma solução eficaz. Diversos passos foram já dados nesse sentido, em outros países, com vista ao alcance de uma concreta solução que se apresente eficaz face ao problema em análise. Em Portugal, especificamente, ainda existe um longo caminho a percorrer.Parental Alienation arises in the context of a divorce or separation in which one of the parents, using their position of superiority and dependence on the minor child, demonstrates a behavior that, actively or passively, incites the child to move away from the other parent. The aim is always to encourage the removal of the minor from one of the parents, however, the possibility of Parental Alienation being practiced by a person close to the minor, other than a parent, as is the case of a grandparent, must be noted.
In this Dissertation, we chose to follow an exploratory, descriptive and explanatory research methodology. Exploratory, because information is researched and questions asked about a specific problem – Parental Alienation; descriptive, in order to analyze Parental Alienation and its characteristics; and explanatory, analyzing and interpreting the problem, pointing out its causes, consequences and possible solutions, specifically in our country.
In a world in which relationships are increasingly fleeting and replaceable, in which marriages are easily broken up and families are separated, Parental Alienation sees a “fertile soil”, where it can expand and grow, just like any plant. But, there it is, lacking treatment in the Portuguese legal system, Parental Alienation constitutes a serious problem to which an effective solution must be given. Several steps have already been taken, in other countries, in this sense, with a view to reaching a concrete solution that is effective in the face of the problem under analysis, in Portugal, specifically, there is still a long way to go

Este trabalho caracteriza as questões que Marcelo Caetano confrontou na transição da década de 1960 para 1970 e as opções adotadas por este decisor face às várias questões de relevância internacional como foi o caso da Guerra Colonial durante a década de 1960 (e a importância do exercício ALCORA), a aproximação à NATO e à Europa, ou seja através de um grau de abertura maior de Portugal no relacionamento com os países ocidentais. Através desta investigação, iremos analisar de forma detalhada todos os momentos positivos e negativos durante o tempo em que Marcelo Caetano foi Presidente do Conselho de Ministros, ou seja, entre o ano de 1968 e 1974.This work aims to analyze the Portuguese Foreign Policy according to the Marcelista vision and study the Continuities and Changes of this Foreign Policy. Marcelo Caetano assumes power with a Colonial Heritage of Wars with the African Colonies. This work characterizes the challenges that Marcelo Caetano faced in the change from the 60s to the 70s, the ways of resolution by Marcelo Caetano in terms of several issues of international relevance such as the case of the Colonial War during the 60s and the importance of the ALCORA exercise, the approximation to NATO and to Europe, that is, through a greater degree of openness of Portugal in the relationship with NATO and with the countries that comprise it and the countries that were included in the EEC that was created on 25 March of 1957 with the Treaty of Rome. Through this theme, we will analyze in detail all the positive and negative moments during the time Marcelo Caetano was President of the Council of Ministers, that is, between 1968 and 1974
