Resilience of logistic service providers facing a port strike: a case study

The purpose of this thesis is to study the impact of a port strike on companies that perform as logistic service providers in a supply chain (SC), here denominated 3PL (third-party logistic providers). These companies are highly dependent on ports to perform their activity, since they provide international services. Consequently, a disruption in a port can seriously impair their business. A stevedores’ strike is one of the possible disruptions that can affect ports. This study aims to analyze the negative effects caused by this disruption, and what strategies 3PLs may implement in order to keep their performance levels stable and have a quick recovery time. Within this objective, the first step will be to establish a theoretical context about the maritime port’s sector and 3PLs in a SC context, to then expand the concept of a resilient SC, and finally to develop a theoretical framework in order to better contextualize the case study. Subsequently, the impact of a port strike will be quantified by using a case study comprising three companies, covering the areas of land and sea distribution and port operations. Information from primary sources was assembled in two phases: first via e-mail and, in a second phase, through a personal interview. The information from secondary sources was obtained through television news, internet and conferences, enabling its cross-analysis. Finally, by analyzing the collected data, it will be possible to draw conclusions about the measures carried out by each company to minimize the negative effects of the strike, thus contributing to a more resilient SC. As a conclusion, a stevedores’ strike will create a snow-ball of negative effects in the SC, degrading all relevant KPIs (key performance indicators) of the 3PLs under study. No mitigation and contingency strategies available proved really effective to reduce the negative effects of a port strike disruption.

A matter of time: Phases of customer co-creation community participation and their impact on customer behavior

Despite the growing relevance of co-creating customer communities only little scientific evidence is available on their impact on transactional behavior of participants. Previous research has mostly used self-reported data or distinguished only between during and pre-community phases obtaining mixed results. However, the author proposes that co-creating community activity takes place in five distinguishable phases and changes in transactional behavior are limited to certain phases. Using 33 months of transactional data of a Dutch online auction provider a study was conducted covering all five phases of the community co-creation process from community planning over community set-up, co-development and co-testing to post-launch. The overall results indicate mixed effects of community participation on the different transactional variables during the co-creation process. Community participation had positive effects on auctions listing behavior at the community set-up, co-development and post-launch phases, whereby the number of auctions listed peaked during the community set-up phase. These results suggest that the impact on transactional behavior differs between co-creation phases and different psychological mechanism limited to certain phases might trigger the respective changes.

Grupo Doméstico e Mudança Social: Abordagens Quantitativas e Qualitativas

Using the domestic group as the privileged unit of analysis, this article provides a study of social change based on the case study of a town in Northeastern Portugal, covering the period between 1944-1994. The article combines different types of sources (ethnographic inquiry, documents from the Parochial Archives) and underscores the importance of the complementary use of qualitative and quantitative methods for a dynamic approach to the study of the domestic group.

What hides behind the fixed-term contracts wage gap?

In Portugal, about 20% of full-time workers are employed under a fixed-term contract. Using a rich longitudinal matched employer-employee dataset for Portugal, with more than 20 million observations and covering the 2002-2012 period, we confirm the common idea that fixed-term contracts are not desirable when compared to permanent ones, by estimating a conditional wage gap of -1.7 log points. Then, we evaluate the sources of that wage penalty by combining a three way high-dimensional fixed effects model with the decomposition of Gelbach (2014), in which the three dimensions considered are the worker’s unobserved ability, the firm’s compensation wage policy and the job title effect. It is shown that the average worker with a fixed-term contract is less productive than his/her permanent counterparts, explaining -3.92 log points of the FTC wage penalty. Additionally, the sorting of workers into lower-paid job titles is also responsible for -0.59 log points of the wage gap. Surprisingly, we found that the allocation of workers among firms mitigates the existing wage penalty (in 4.23 log points), as fixed-term workers are concentrated into firms with a more generous compensation policy. Finally, following Figueiredo et al. (2014), we further control for the worker-firm match characteristics and reach the conclusion that fixed-term employment relationships have an overrepresentation of low quality worker-firm matches, explaining 0.65 log points of the FTC wage penalty.

Non-gyrator type active inductors

Modern CMOS radio frequency (RF) Receivers have enabled efficient and increasing applications. The main requirement is to have system in a single chip, in order to minimize area and cost. For the purpose it is required the development of inductorless circuits for the key blocks of an RF receiver. Examples of this key blocks are RC oscillators, RF band pass filters, and Low Noise Amplifiers. The present dissertation presents an inductorless wideband MOSFET-only RF Non-Gyrator Type of Active Inductors with low area, low cost, and very low power, capable of covering the whole WMTS, and ISM, band and intended for biomedical applications. The proposed circuit is based on a floating capacitor connected between two controlled current sources. The first current source, which is controlled by the circuit input voltage, has two objectives: supply current to the capacitor (

Cylindrical spinning rotor gauge — A new approach for vacuum measurement

The spinning rotor gauge (SRG) is one of the most interesting vacuum gauges ever made, covering a pressure range of over seven orders of magnitude, with minimal gas interference (no pumping, ionization or heating of the measured gas), and a great stability of less than 1% drift per year. But despite its remarkable properties, apparently the SRG has not been further developed since the eighties, when it gained commercial interest. In this context, this dissertation aims at providing a starting point for a new line of investigation regarding this instrument, focused on the rotor itself. A brief study of different rotor geometries is provided, including a comparison between a cylindrical rotor and a spherical one. A cylindrical spinning rotor gauge (CSRG) is then proposed, based on the original SRG, but requiring a completely new lateral damping system. A prototype was built and tested against a non calibrated reference gauge.

A protecção jurídica do consumidor em Angola

The scope of the present work is to study the legal protection conferred upon the consumer in Angola, especially as regards electronic communication agreements. Its purpose is to promote consumers’ rights and contribute to its defence given the relatively privileged position of professionals in their relationship with consumers. With this in mind, we have made a description of the Consumer Law in Angola based on the Angolan Constitution (as the law that establishes the fundamental rights and guarantees of citizens) and on the Consumer’s Defence Law, which, as the basic law regarding consumers’ rights, provides the framework for this dissertation. We have analysed several aspects relating to consumer relationships, starting from its concept and rights of consumers and covering the legal and contractual mechanisms put in place for their protection. We have also analysed the Advertising Law with a view to better understand consumer’s rights before advertising campaigns carried out by professionals whilst promoting their goods and services and, additionally, to understand the duties and principles that shall be complied with in such campaigns with the purpose to protect the rights and interests of consumers. From a criminal point of view, we have briefly covered the crimes against consumers provided for in the Penal Code and the Law of Infractions against the Economy. In the second part of this work, we have summarised the institutions that protect the rights and interests of consumers, which include the Public Prosecutor Office, the National Institute for the Defence of the Consumers and the Consumers’ Associations. The third and last part of this work covers electronic communications agreements. Given the fact that there is no specific legislation in this matter, our analysis was based on the Civil Code – specifically the part relating to contracts – the Law on General Contractual Terms and Conditions and the Consumer’s Defence Law. We have analysed the formation of contracts, compliance and consumers’ rights resulting from contract breach. We further have appealed to the Angolan legislator to legislate certain aspects of consumer relationships, especially those where breach of consumers’ rights are blatant and facilitated by the lack of specific laws addressing such cases.

Cultural journalism in a digital environment : new models, practices and possibilities

Both culture coverage and digital journalism are contemporary phenomena that have undergone several transformations within a short period of time. Whenever the media enters a period of uncertainty such as the present one, there is an attempt to innovate in order to seek sustainability, skip the crisis or find a new public. This indicates that there are new trends to be understood and explored, i.e., how are media innovating in a digital environment? Not only does the professional debate about the future of journalism justify the need to explore the issue, but so do the academic approaches to cultural journalism. However, none of the studies so far have considered innovation as a motto or driver and tried to explain how the media are covering culture, achieving sustainability and engaging with the readers in a digital environment. This research examines how European media which specialize in culture or have an important cultural section are innovating in a digital environment. Specifically, we see how these innovation strategies are being taken in relation to the approach to culture and dominant cultural areas, editorial models, the use of digital tools for telling stories, overall brand positioning and extensions, engagement with the public and business models. We conducted a mixed methods study combining case studies of four media projects, which integrates qualitative web features and content analysis, with quantitative web content analysis. Two major general-interest journalistic brands which started as physical newspapers – The Guardian (London, UK) and Público (Lisbon, Portugal) – a magazine specialized in international affairs, culture and design – Monocle (London, UK) – and a native digital media project that was launched by a cultural organization – Notodo, by La Fábrica – were the four case studies chosen. Findings suggest, on one hand, that we are witnessing a paradigm shift in culture coverage in a digital environment, challenging traditional boundaries related to cultural themes and scope, angles, genres, content format and delivery, engagement and business models. Innovation in the four case studies lies especially along the product dimensions (format and content), brand positioning and process (business model and ways to engage with users). On the other hand, there are still perennial values that are crucial to innovation and sustainability, such as commitment to journalism, consistency (to the reader, to brand extensions and to the advertiser), intelligent differentiation and the capability of knowing what innovation means and how it can be applied, since this thesis also confirms that one formula doesn´t suit all. Changing minds, exceeding cultural inertia and optimizing the memory of the websites, looking at them as living, organic bodies, which continuously interact with the readers in many different ways, and not as a closed collection of articles, are still the main challenges for some media.

A Presença islâmica em al-Qasr : uma análise sobre o urbanismo e o sistema defensivo

Alcácer do Sal é uma cidade que esteve desde sempre ligada ao rio Sado, permitindo essa mesma ligação, que nela se fossem fixando ao longo do tempo, distintos povos, provindos das mais diversas partes do mundo. Esta ocupação por parte das populações, só foi possível, porque o território era abundante em recursos naturais e, entre eles, possuía solos bastante férteis para a agricultura. Uma das comunidades que mais marcas deixou da sua presença naquele núcleo urbano, foi, sem dúvida, a muçulmana, tal como se pode verificar no topónimo que dá o nome à cidade, assim como pela presença dos vários vestígios materiais, como a imponente fortificação militar, que se ergue na colina mais alta da povoação, assim como pelas estruturas e espólios encontrados nas diversas intervenções arqueológicas realizadas naquela cidade. Tendo em conta estes aspetos, esta dissertação pretende fazer uma aproximação ao estudo do urbanismo da medina islâmica de al-Qasr, abarcando cronologicamente o século IX, altura em que os Banu Danis se fixam na cidade, até aos inícios do século XIII, correspondente à última fase de ocupação muçulmana da cidade.
