How business models can affect startup failure : Monkey´n Apps Business Study

Mestrado em Gestão/MBAAs startups são jovens empresas de base tecnológica focadas no desenvolvimento de produtos ou serviços de ponta, sob condições de incerteza. Nesse cenário, um modelo de negócios inadequado pode levar a uma falha nos negócios, pois o modelo de negócios descreve a arquitetura dos elementos que permitem que uma organização crie, configure e valor apropriado. Esta dissertação tem como objetivo identificar como os modelos de negócios estão associados ao fracasso de startups. Para esse fim, usamos um único estudo de caso baseado em uma startup brasileira, a Monkey'n Apps. Os dados foram coletados por meio de entrevistas com o fundador e um funcionário. A análise avalia as construções apresentadas no modelo de negócios integrado de Wirtz (2016) e, em seguida, relacionamos esses modelos parciais aos processos de criação de valor, configuração de valor e apropriação de valor. Nossos resultados sugerem que a inicialização falhou devido ao modelo de recursos. Apesar de ser o modelo parcial mais crítico, o modelo de recursos foi caracterizado por um desalinhamento entre os fundadores, o que levou a uma liderança fraca. A falta de habilidades gerenciais contribuiu para deteriorar o ambiente da empresa, que mais tarde deixou o fundador ignorar seu principal ativo, seus funcionários.Startups are young technology-based companies focused on developing state-of-the-art products or services under conditions of uncertainty. In this scenario, an inappropriate business model can lead to business failure since the business model describes the architecture of the elements that allow an organization to create, configure, and appropriate value. This dissertation aims to identify how business models are associated with the failure of startups. For this purpose, we use a single case-study based on one Brazilian startup, Monkey'n Apps. The data was collected through interviews with the founder and one employee. Our analyses evaluate the constructs presented on Wirtz's (2016) integrated business model and then we relate those partial models to the processes of value creation, value configuration and value appropriation. Our results suggest that the start-up failed because of the resource model. Despite being the most critical partial model, the resource model was characterized by a misalignment between the founders led to a poor leadership. The lack of management skills contributed deteriorate the environment in the company that later on let the founder to ignore their primary asset, their employees.info:eu-repo/semantics/publishedVersio

Women’s Experiences: Memories of Portuguese Revolution

In this article I attempt to analyze the social memories of wives of soldiers in service on April 25th 1974, through the methodology of analysis recommended by Adele Clarke (2005), using data collected in 11 interviews conducted between 2005 and 2008 under a PhD project. As a conceptual framework I adopt the perspective of social memory in the tradition of Halbwachs (1992) and following Marc Augé (2001) and Paul Ricoeur (2004), which emphasizes the social and collective memory and points out the dynamic role it plays in building a meaning to the world. This analysis takes into account the dimensions of work, family, education, politics and social life, social and economic conditions and the expectations and dreams on which the interviewees draw comparisons between 1974 and the present and also produce judgments

Migmatitos e retroeclogitos do bloco arqueano Campo Grande, província Borborema, NE do Brasil

O Bloco Campo Grande (BCG) é constituído por rochas arqueanas de 2,9 Ga e 2,65 Ga retrabalhadas durante eventos orogênicos riacianos (2,2 – 1,95 Ga) e neoproterozoicos (630 – 560 Ma). O bloco compreende uma área de cerca de 1500 km2, com geometria elipsoidal, eixo SSW-NNE, na porção central do embasamento do Domínio Rio Grande do Norte, Província Borborema. O BCG é constituído por: 1. Complexo gnáissico-migmatito representado por biotita gnaisse bandado, granada-biotita gnaisse lepidogranoblástico e K-feldspato alcali gnaisse porfiroblástico. Os migmatitos são separados em paleossomas tonalíticos de 2,9 Ga, leucossomas in source ou in situ de composição granítica de 1,95 Ga e leucossomas injetados (veios pegmatíticos) de 580 – 560 Ma, com composição alcalina. 2. Rochas toleíticas ultramáficas de 2.69 – 2.52 Ga, formadas por cumulatos de ortopiroxênio (En 74,9 - 80,9% e 10,7 - 14,1% wt. de FeO) e clinopiroxênio (diopsídio e augita, En 31 - 42% e 9,9 - 16,1% wt. de MgO), parcialmente retrogradados para anfibólios da série cummingtonita (Mg) - grunerita (Fe). 3. Rochas metamáficas, com assembleia mineral formada por Mg-hornblenda, Fe-hornblenda, pargasita, granada, plagioclásio e clinopiroxênio. Neste grupo, enquadra-se sequência de corpos desmembrados (boudinados) constituídos por rutilo-clinopiroxênio-granada anfibolito com textura granoblástica, contendo granada com até 32% da molécula de piropo, crescimento simplectítico de Pl + Cpx e corona de Amph + Pl. As rochas metamáficas possuem protolito magmático de 2,65 Ga e registram dois eventos metamórficos, o primeiro em 2,0 Ga e o segundo no intervalo de 630 – 590 Ma. 4. rochas supracrustais neoproterozoicas, representadas por paragnaisses finamente bandados, granada-biotita xistos e anfibólio-epidoto calciossilicáticas que também ocorrem como lentes concordantes com a foliação principal. Idades modelo TDM e valores positivos e negativos de εNd(t) em rocha total revelam épocas acrescionárias em 3,3 – 3,1 Ga, 2,9 Ga e 2,7 – 2,5 Ga, com aporte de material juvenil e retrabalhamento de fontes mais antigas já no Arqueano. Na porção leste desse núcleo arqueano são mapeados complexos ortognáissicos ricos em K-feldspato, cujos protólitos apresentam idade de cristalização de 2,23 – 2,18 Ga e composição calcioalcalina de alto K. Os ortognaisses possuem TDM entre 2,59 e 2,46 Ga e εNd(t) negativos, suportando acresção por arcos magmáticos durante o Riaciano. Plutons graníticos neoproterozoicos (600 Ma) alojados em zonas de cisalhamento de escala regional delimitam o Bloco Campo Grande a leste e a oeste. Os dados obtidos mostram que a área de estudo apresenta intenso processo de reciclagem crustal e acresção de xviii arcos magmáticos do Arqueano ao Neoproterozoico, representando assim o primeiro registro, em escala de bloco, dos processos quelogênicos necessários para a diferenciação e o crecimento da crosta continental, anteriormente observado apenas em extensas áreas continentais, com mais de 1.000.000 km2. Além disso, a geração de crosta continental em 2,9 Ga é rara, com registros de apenas outras duas ocorrências no Gondwana Ocidental, distantes mais de 2000 km da região de Campo Grande.FAPDFThe Campo Grande Block (CGB) consists of 2.9 Ga and 2.65 Ga Archean rocks reworked during Paleoproterozoic (2.2 - 1.95 Ga) and Neoproterozoic (630 - 560 Ma) orogenic events. The CGB comprises an area of about 1500 km2, with ellipsoidal geometry, in the central portion of the Rio Grande do Norte Domain, Borborema Province. The BCG consists of: 1. Migmatite–gneiss complex represented by banded biotite gneiss, garnet biotite gneiss and course-grained porphyritic K-feldspar alkali gneiss. Migmatite rocks are separated into 2.9 Ga tonalitic paleosomes, 1.95 Ga in-source or in-situ granitic leucosomes, and 580 - 560 Ma injected alkaline leucosomes. 2. Ultramafic tholeiitic rocks formed by 2.69 - 2.52 Ga cumulates of orthopyroxenite (En 74.9 - 80.9% and 10.7 - 14.1% wt. Of FeO) and clinopyroxenite (diopside and augite, En 31 - 42% and 9.9 - 16.1% wt. Of MgO) partially retrograded to amphiboles of the cummingtonite (Mg) – grunerite (Fe) series. 3. Metamorphic rocks with mineral assemblage consisting of Mg-hornblende, Fe-hornblenda, pargasite, garnet, plagioclase and clinopyroxene. This group includes a sequence of boudinated bodies consisting of rutile-clinopyroxene-amphibolite garnet with granoblastic texture, containing garnet with up to 32% of the pyrope, symplectite growth of Pl + Cpx, and Amph + Pl coronae. These rocks have 2.65 Ga magmatic protolith and record two metamorphic events, the first at 2.0 Ga and the second at 630 - 590 Ma. Supracrustal and calc–silicate rocks also occur as lenses concordant with the main foliation. Despite the several collisional events from the Archean to Neoproterozoic times, relicts of magmatic arc systems were preserved in Northeast Brazil as the main process for the growth and differentiation of the continental crust from 2.9 Ga onwards. The transition between Meso- and Neoarchean is characterized by the compositional change from 2.9 Ga calcium-rich (tonalite) to 2.7 Ga potassium-rich (sanukitoid) magmatism. In addition, a minor volume of 2.65 Ga tholeiitic magmatism also is recorded. The 2.9-2.7 Ga calc-alkaline and tholeiitic crust fragments were intensely reworked during Rhyacian (2.25-1.95 Ga) and Neoproterozoic (627-566 Ma) orogenic events. Rhyacian high-K2O igneous activity is the most pervasive evidence of a strong reworking process that took place in a post-collisional tectonic setting. Similar Archean crust formation at 2.9 Ga and recycling during Paleo- and Neoproterozoic tectonic events is described in the West Africa counterpart of the Borborema Province. Two others 2.9 Ga old crust fragments are recorded in the South American continent, namely in the Amazonian and São Francisco cratons, more than 2000 km apart from the studied area in northeastern Brazil. The results support episodic crustal growth with five short crustal formation periods at ca. 2.9 Ga, 2.65 Ga, 2.25 Ga, 2.0 Ga and 0.6 Ga. About 60% of the crust was formed in the Archean, between 2.9 Ga and 2.65 Ga; the remaining 40% of accretionary crustal generation was added in the 2.0 to 2.0 Ga Rhyacian period. Crustal recycling of the Archean and Proterozoic protolith sources require chelogenic processes, which represent successive arc accretions surrounding an older core, becoming younger toward the margin, to explain the age zonation pattern displayed in the Archean core evolution. A similar process is observed only in large continental areas, more than 1.000,000 km2 in size, as in the North American continent basement and in the Amazonian Craton. However, it had never been describe in the minor crustal block scale, as in the Campo Grande complex in Northeast Brazil

Nucleus-Cytoskeleton Crosstalk During Mitotic Entry

In preparation for mitosis, cells undergo extensive reorganization of the cytoskeleton and nucleus, so that chromosomes can be efficiently segregated into two daughter cells. Coordination of these cytoskeletal and nuclear events occurs through biochemical regulatory pathways, orchestrated by Cyclin-CDK activity. However, recent studies provide evidence that physical forces are also involved in the early steps of spindle assembly. Here, we will review how the crosstalk of physical forces and biochemical signals coordinates nuclear and cytoplasmic events during the G2-M transition, to ensure efficient spindle assembly and faithful chromosome segregation.Work in the Biophysics of Cell Division Laboratory was supported by Portuguese funds through FCT—Fundação para a Ciência e a Tecnologia/Ministério da Ciência, Tecnologia e Ensino Superior in the framework of the project PTDC/BIA-CEL/6740/2020.

Non-technological innovation activities mediate the impacts of the intra- and extra-organizational contexts on technological innovation outputs

UID/SOC/04647/2013The increasing interest on innovation studies and, particularly, on technological innovation has been attributed to innovation’s social and economic relevance. Still, organizational and marketing innovation activities, which are critical for firms’ economic performance, have been far less studied. This paper will specifically characterize these non-technological innovation processes, their firm and environmental underpinnings, as well as their impacts on technological innovation outputs (i.e., goods and services). For this purpose, it focuses on the Information and Communication Technology (ICT) services sector in Portugal between 2010 and 2012. This period is characterized by a socio-economic crisis context that is concomitant to decreases in firms’ innovation activities and economic performance. Under this challenging scenario, our data shows that organizational and/or marketing innovation activities mediate the impacts of firms’ 1) assets; 2) research activities and empowerment strategies; and 3) structure and climate of decision-making processes, on technological innovation outputs. This study reveals that decreases in innovative performance during the socio-economic crisis could be attributed not only to unfavourable firm and environmental contexts, but also to the absence of non-technological innovation activities. As such, it is suggested that support of non-technological innovation by firms’ managers and, at a broader level, by public policies is critical for launching of new products and services to the markets.publishersversionpublishe

Extreme Events Decision Making in Transport Networks: A Holistic Approach Using Emergency Scenarios and Decision Making Theory

This paper proposes a novel method to analyse decision-making during extreme events. The method is based on Decision-making Theory and aims at understanding how emergency managers make decisions during disasters. A data collection framework and an analysis method were conceptualized to capture participant’s behaviour, perception and understanding throughout a game-board simulation exercise, which emulates an earthquake disaster scenario affecting transport systems. The method evaluates the participant’s actions in order to identify decision-making patterns, strengths and weaknesses. A set of case studies has shown two typical patterns, namely: a) Support immediate rescue; b) Support lifelines recovery. Good decision-making practices regard to objective-oriented decision making, understanding of conflicting priorities and appropriate resource management. Weaknesses are associated with comprehending relationships between community/environment and projecting future scenarios. Overall, the case study’s results demonstrate the efficiency and robustness of the proposed method to analyse decision making during disasters

Animal-assisted therapy for Alzheimer patients using virtual reality

A doença de Alzheimer é a principal causa de demência. Trata-se de uma doença neurodegenerativa incurável que conduz a falhas cognitivas e problemas comportamentais. A demência constitui um enorme fardo social e económico para os doentes e para os cuidadores. A medicação ajuda a prevenir alguns sintomas da doença, mas não cura podendo revelar efeitos secundários indesejáveis. Algumas terapias alternativas têm vindo a ser exploradas, por exemplo a terapia animal (AAT). Para evitar as desvantagens da terapia animal, como a necessidade de treino, foi desenvolvida uma solução com realidade virtual. Realizamos um estudo com 12 pacientes diagnosticados com demência para perceber que tecnologias e modos de interação são mais adequados para esta população. Os resultados indicam que tecnologias com interação direta são mais adequadas (por exemplo Tablet ou AR). Foi desenvolvido um jogo de interação com animal para tablets. Realizou-se um estudo com 10 pacientes diagnosticados com demência num centro de dia. Este estudo tinha o objetivo de examinar a aplicabilidade desta ferramenta nesta população e perceber se uma sessão de terapia animal virtual poderia ter efeitos na disposição do participante, através da avaliação das suas respostas emocionais. Os participantes responderam a questionários pré- e pós-intervenção para obtenção de informação relativa ao seu estado emocional e à sua perceção da sessão de jogo. Foi utilizado um questionário destinado ao terapeuta que registou a sua opinião relativa aos efeitos no participante. Os resultados indicam melhorias na disposição dos participantes, uma boa aceitação e usabilidade desta abordagem e respostas emocionais positivas.The Alzheimer’s Disease is the main cause of dementia. It is incurable and regarded as a neurodegenerative disease that leads to cognitive and behavioral impairment. Dementia brings along a heavy burden from both a social and economic perspective. Traditional medication helps in slowing down the disease but is not able to cure it, and it may also bring undesirable side-effects. Alternative therapies are being further explored, being one of them Animal-Assisted Therapy (AAT). To avoid the disadvantages of conventional AAT, such as the need for trained animals, or hygiene issues, a Virtual Reality approach was adopted. We conducted a pilot study with 12 dementia patients to understand which technologies and interaction modalities were preferred when developing for this population. Devices that promote direct interaction were preferred (Tablet and AR) so, combining the positive aspects of traditional AAT and the promising aid of VR, an animal interaction tablet game was developed for this population. This study, conducted with 10 dementia patients in a daily-care center, aimed to examine whether a session of virtual AAT was feasible and able to produce any changes in the mood of participants, evaluating the acceptance and emotional responses as well. Participants completed pre- and post-intervention questionnaires to assess their mood and perception of the game session and a therapist was also asked to provide insight on each participant. Therapist’s reports and observations reveal positive mood changes, good acceptance by the patients and positive emotional responses

Marketing digital no Instagram: o caso de empresas da área da beleza no município de João Pessoa

O setor de beleza está passando por uma grande revolução com a utilização das mídias sociais como ferramenta de marketing digital. O objetivo deste estudo é o de entender o impacto do instagram como plataforma de s-commerce, o processo de vender via redes sociais. A fim de alcançar estes objetivos, uma extensa pesquisa bibliográfica foi realizada sobre o tema e um questionário foi aplicado a uma amostra de empresas da indústria da beleza no município de João Pessoa. Os resultados indicam que as empresas veem o Instagram como uma vitrine virtual de suas marcas, que as empresas utilizam a rede social para promover seu trabalho com a criação de conteúdo, mas que existe um amplo espaço para o uso mais eficiente dessa ferramenta, como a criação de conteúdo programado e a utilização das métricas de acesso disponibilizados pelo instagram

A imagem enquanto leitura e escrita do mundo: "leveleve" e a ferida colonial em São Tomé

Esta tese foi desenvolvida para perceber como a imagem ativa os pontos de vista das pessoas nas roças de São Tomé. A partir de conjuntos de imagens, narrativas visuais, foi possível observar como os santomenses interpretam a vida, seus saberes e suas histórias. As narrativas foram montadas para funcionar como experiências de interações entre corpos, lugares e imagens. Os recursos utilizados foram o Jogo da Memória, o Cinema na Roça, o Círculo Cultural e o Museu das Invasões, além de uma exposição fotográfica. Todos eles se conectam e contribuem para a prática de uma Antropologia ecológica com as pessoas, além de terem sido elaborados enquanto visualidade de resistência à modernidade. Em dois meses junto com as pessoas de São Tomé, fomos moldando a metodologia e a teoria de acordo com cada atividade, revisitando a história colonial, reconhecendo aspectos culturais da ilha, redefinindo conceitos como liberdade, tempo, conhecimento e memória. As reflexões decorrentes trazem a ideia da roça/comunidade, ou simplesmente comunidade, como categorias nativas que ressituam a roça e a empresa agrícola. Neste cenário, o "leveleve" salta como um estilo de vida santomense, no qual a categoria "futuro" é inexistente como parte do dia a dia e da história. Por fim, esta tese chama a atenção para o poder das imagens na tessitura dos discursos e para a necessidade constante de presentificar a diversidade de vozes e visualidades nas narrativas, constituindo-se, portanto, como projeto que continua em outras publicações digitais, alimentadas ao longo da vida, em diálogo e transformações.This thesis was developed to understand how image activates the points of view of people in the plantation estates (Roças) of Sao Tome. From sets of images, visual narratives, it was possible to observe how the Sao Tomeans interpret life, their knowledge and their stories. The narratives were set up to function as experiences of interactions between bodies, places and images. The resources used were the Memory Game, the Cinema in the Roca, the Cultural Circle and the Museum of Invasions, in addition to a photographic exhibition. All of them connect and contribute to the practice of an ecological Anthropology with people, in addition to being elaborated as a visuality of resistance to modernity. In two months together with the people of Sao Tome, we shaped the methodology and theory according to each activity, revisiting colonial history, recognizing cultural aspects of the island, redefining concepts such as freedom, time, knowledge and memory. The resulting reflections bring the idea of the rocas / community or, simply, community as native categories that re-situate the roca and the agriculture company. In this scenario, the "leve-leve" stands out like a Santomean lifestyle, in which the category future does not exist as part of everyday life and history. Finally, this thesis brings attention to the power of images in the tessitura of discourses and to the constant need to make present the diversity of voices and visualities in the narratives, thus constituting itself as a project that continues in other digital publications, updated along the years, in dialogue and transformations
