[pt] TRABALHO, CONTROLE E RESISTÊNCIA: O CASO DOS TRABALHADORES DE ENTREGA POR APLICATIVOS / [en] WORK, CONTROL AND RESISTANCE: THE CASE OF APP DELIVERY WORKERS

FERNANDO DO AMARAL PEREIRA 12 May 2022 (has links)
[pt] Em um contexto de profundas transformações nas relações de trabalho causadas pela tecnologia, milhares de entregadores se movimentam pelas ruas brasileiras entregando comida e outros itens sob o comando de plataformas digitais. Essa modalidade de trabalho, em ascensão nos últimos anos, tem sido alvo do interesse de pesquisadores em função das peculiaridades que a caracterizam. Um aspecto relevante a ser estudado diz respeito ao controle sobre esse tipo de trabalho. Nesta direção, a presente dissertação buscou entender de que forma o controle exercido pelos aplicativos é percebido pelos trabalhadores de entrega por aplicativos em suas relações de trabalho e quais as suas formas de resistência. Para isso foi feita uma netnografia em redes sociais que analisou 21 grupos no Facebook com 136 postagens de entregadores, e foi criado um grupo, Conversas sobre o trabalho por aplicativos, para complementar a coleta de dados. Todo o material coletado foi analisado com base em análise temática. A teoria do processo de trabalho de Harry Braverman foi utilizada para entender como o controle se manifesta nessas relações trabalho, desde o controle técnico e burocrático até o controle normativo e neo-normativo, bem como nas transformações que a tecnologia tem criado nas relações de trabalho e no controle algorítmico sobre os trabalhadores, exercido pelas plataformas digitais de entrega de comida, operando no Brasil. Os principais achados da pesquisa indicam que, embora o trabalho de entregador tenha características claras de precarização e intensificação do trabalho, sua inserção no contexto brasileiro, marcado por desemprego sistêmico e estrutural, faz com que essa atividade seja considerada como uma opção melhor do que o trabalho formal, sendo considerada mais garantida e, até mesmo, pertencente a uma elite entre os precarizados. Além disso, a construção identitária dos entregadores, marcada por discursos de reforço de estereótipos de masculinidade, como o do homem provedor e pai de família, bem como discursos de empreendedorismo, de liberdade ressignificada, ao depender somente do esforço pessoal do indivíduo, mascaram os aspectos deletérios desse tipo de trabalho. Argumenta-se que esses fatores contribuem para a produção do consentimento e enfraquecimento das possibilidades de resistência, da representação sindical e da transformação da realidade dos entregadores frente aos aplicativos. / [en] In a context of deep changes in labor relations caused by technology, thousands of food-delivery worker move through Brazilian streets delivering food and other stuffs by digital platforms. This kinda of work, which has been increase in recent years, has been the target of interest by researchers due to the peculiarities that characterize it. A relevant aspect to be studied concerns the control over this type of work. In this direction, the present dissertation get to understand how the control by applications is perceive by food-delivery worker through applications in their work relationships and what are their forms of resistance. For this, a netnography was carried out on social networks that had analyzed 21 groups on Facebook with 136 posts from food-delivery worker, and a group was created, conversations about work through applications. All material collected was analyzed based on thematic analysis. Harry Braverman s labor process theory was used to understand how control manifests itself in these labor relationships, from technical and bureaucratic control to normative and neonormative control, as well as the transformations that technology has created in labor relationships. and in the algorithmic control over workers, exercised by digital food delivery platforms, operating in Brazil. The main findings of the research indicate that, although the delivery job has clear characteristics of precariousness and work intensification, its insertion in the Brazilian context, marked by systemic and structural unemployment, makes this activity to be considered a better option than the formal work, being considered more guaranteed and even belonging to an elite in the middle of the precariat. In addition, the identity construction of the food-delivery worker, marked by discourses that reinforce masculinity stereotypes, such as the provider and family man, as well as discourses of entrepreneurship, of resignified and guaranteed freedom, depending only on the individual s personal effort, mask the deleterious aspects of this type of work. It is argued that these factors contribute to the production of consent and weakening of the possibilities of resistance, union representation and the transformation of the delivery people s reality in front of the applications.

IS-implementation: a tri-motors theory of organizational change. Case study of how an IT-enabled process of organizational change because of the presence of a teleological, life-cycle, and dialectical motor unfolds within a Dutch government organization.

Winkel, Geellis January 2010 (has links)
The reason for the study is that IT-enabled organizational change processes such as information system implementations have high costs and disappointing results. Studies to identify causes of the mentioned failures are mainly based on a variance approach. This study applies another approach which is not yet performed in this field of research and affects several themes. Based on a process approach data is compared with ideal-process theories to identify the generative mechanisms causing the unfolding of the process. Thus, the study identifies a recipe and not the ingredients.

The complex internationalization process unfolded : The case of Atlas Copco’s entry into the Chinese mid-market

Eriksson, Mikael January 2016 (has links)
Despite its contemporary relevance, we still have limited empirical knowledge about the forces underlying complex internationalization processes as when multinational corporations (MNCs) seek to enter new growing markets. Based on a real-time process study comprising ninety interviews and two hundred hours of observation made between 2009 and 2012, Atlas Copco’s entry into the Chinese mid-market was investigated. The intra-organizational analysis showed that three inter-related processes were underlying Atlas’ market entry and the results suggest that multiple interrelated motors may drive many contemporary internationalization processes. The processes identified are a sequential strategy process, an evolutionary process which shows that routines changed, and a political process. A somewhat surprising finding is that the main driver of internationalization according to received theory, the firm’s accumulated experiences, not only can drive internationalization, but may also hamper MNC managers’ possibilities to enter many of today’s new and growing markets. The findings add to our knowledge of the internationalization process in an increasingly complex international business setting, and especially highlight the need to distinguish between the sequential strategy process – more in line with received theory – and the other processes, in order to get a more full-fledged picture of what internationalization in large MNCs is all about.

Women in the Swedish Armed Forces : How does the Swedish Armed Forces promote women in order to attract them to their organisation?

Andreasson, Ann-Sofie January 2016 (has links)
The following Bachelor thesis is analysing how the Swedish armed forces promotes women in order to attract them to their organisation. Specifically it investigates (1) "How does the Swedish armed forces break the social norms of what it means to be a soldier?" (2) "How do they present a gender equal division of labour?" (3) "How do they try to affect women´s attitude towards the organisation?" This study investigates the Swedish armed forces, an organisation with a great underrepresentation of women. The underrepresentation of women is something that the Swedish armed forces openly tries to change through their marketing. This thesis is a single case study with both qualitative and quantitative approach, using Harding´s gender process theory in a descriptive design. By gathering television commercials from the Swedish armed forces user page on YouTube, I explore how the Swedish armed forces tries to minimize the underrepresentation of women. Their strategies are analysed by using Harding´s three gender processes. The results show that the organisation is active in all three processes, but focuses on breaking the social norms of what it means to be a soldier.

The Neural Correlates of Emotion and Reason in Moral Cognition

Blomgren, Ami January 2019 (has links)
Humans are a social species. Automatic affective responses generated by neural systems wired into our brains create a moral intuition or “gut-feeling” of wrong and right that guides our moral judgments. Humans are also an intelligent, problem solving and planning species with neural structures that enable cognitive control and the ability to reason about the costs and benefits of decisions, and moral judgments, not the least. Previous research suggests that moral intuition and moral reasoning operates on different neural networks - a dual process of moral cognition, that sometimes gives rise to an inner conflict in moral judgments. Early lesion studies found correlations between damage to the ventromedial prefrontal cortex (VMPFC) and changes in moral behaviour. This has been further established through brain imaging studies and the suggestion is that VMPFC mediates affective signals from the amygdala in moral decision making and is highly involved in generating the gut-feeling of right and wrong. However, some moral issues are complex and demand higher level processing than intuition, and the dorsolateral prefrontal cortex (DLPFC) seems to be responsible for the rational, cost-benefit reasoning during moral judgments. Further, recent research suggests that during moral judgments, the brain employ neural systems that generates the representation of value, perspective and cognitive control as well as the representation of the mental and emotional states of others. The present thesis aims to investigate prominent and up to date research on the neural correlates of necessary components in moral cognition, and to examine the function of moral intuition versus reason in relation to current complex moral issues. Moral intuition is supposedly an adaption to favour “us” before “them”, not to be concerned with large scale cooperation, which may explain why we treat many moral issues with ignorance. Understanding how the moral brain works involve understanding what sort of tasks the neural mechanisms in moral cognition evolved to handle, which may explain why some modern issues are so difficult to solve.

Preschool teachers approach in suspected cases of domestic violence

Simba, Danielle, Rostek, Johanna January 2019 (has links)
Domestic violence is a public health and international problem. Previous research outlined the extensivity of the problem internationally and the missing approaches of professionals who work with young children. The study aims to explore the methods and routines used by preschool teachers in approaching suspected cases of domestic violence among preschool children in Sweden. The results show that there are only a few available methods and routines given by governmental agencies in guiding the preschool teachers to approach such cases. As an alternative, the preschool teachers themselves develop individual approaches like observation, documentation, and collaboration with different actors involved. The interviews were conducted with semi-structured interviews with four preschool teachers to give a deeper understanding of their knowledge about the topic and experiences with suspected cases of domestic violence and methods and routines. The normalization process theory (NPT) was used to highlight the complexity of modifying methods and routines for complex problems e.g. domestic violence. The method of deductive thematic analysis provided pre-determined themes connected to the theory and new themes emerged from the data during the analysis process.

Health and the Spiritual Self: Development and Application of a Theory and Measure of the Process of Healthy Change

Faull, Kieren January 2006 (has links)
The overall goal of the thesis was to investigate the nature of the healthy human self and the process of achieving health. This was undertaken by reviewing established self-theory and presenting a summary of each theory and its position with regard to self-composition, self-agency and the nature of the healthy self. An inclusive self-theory was then developed, congruent with reviewed literature, which positioned spirituality as the essential core of self. From the foundational Spiritual Theory of Self and the findings of the first study in this thesis, the Health Change Process Theory was developed to explain and predict how people achieve sustainable health. Three subsequent studies resulted in the construction and testing of a quantitative measure which enabled scientific investigation of the nature of the healthy self and the process of achieving health. Method The methodology of the four studies in this thesis was based on the instrumental approach which posits that, while there are procedural differences between qualitative and quantitative methodologies, philosophically speaking, there is no fundamental difference as they are both equally applicable and valuable. Consequently, the methodology judged to be the most appropriate instrument to investigate each study's topic of inquiry was chosen rather than allegiance to either qualitative or quantitative methodology. The first study was qualitative, as it investigated the definition of health and the process by which it was achieved from the perspective of 30 people with chronic musculoskeletal impairments. The findings from this study provided the theoretical basis for the three subsequent questionnaire development and validation studies. The second study used qualitative methodology with 59 participants to identify participant-generated items used in a new quantitative holistic health questionnaire and then employed quantitative methods to perform preliminary tests of the reliability and validity of this measure. The third study used quantitative methods with 233 participants to evaluate more robustly the reliability, content and concurrent validity of the original developmental measure and another, behaviourally-orientated assessment instrument, which used the identical item content but re-framed in the past tense. The fourth study employed qualitative and quantitative methods with 205 participants to evaluate the clinical validity of the scale found to possess reliability and validity in the previous investigation. Results The critical review of self-theory concluded with the development of the Spiritual Theory of Self. The initial study supported this theory as a robust explanation and predictor of the determinants of a healthy self. Furthermore, the findings of this study and a review of relevant literature concluded with the development of a Health Change Process Theory, which was based on the Spiritual Theory of Self. The Health Change Process Theory explains and predicts the process by which a healthy self develops. The subsequent questionnaire development and validation studies sought to provide a quantitative holistic assessment tool, congruent with the Health Change Process Theory, and found the 28-item QE Health Scale (QEHS) to be a reliable and valid measure of holistic health. These results also demonstrated that the Health Change Process Theory and the underpinning Spiritual Theory of Self were robust. With regard to clinical application, the QEHS was found to aid assessment, therapeutic intervention, a client-centred holistic approach to healthcare and evidenced-based practice. The Patient Profile, derived from QEHS responses, provided a tool that enabled theory to be applied to practice by identifying the key indicator personal attributes determining holistic health status. Conclusion The research results demonstrated that the Spiritual Theory of Self and the Health Change Process Theory provide valid explanations of the constructs that enable people with musculoskeletal disorders to remain otherwise healthy with such conditions. Furthermore, the relationship between the findings and established self-theories suggest that the Spiritual Theory of Self and the Health Change Process Theory may advance knowledge of the predictors and interventions that enable all people to undertake a health-enhancing process of change when confronted with adversity. The QEHS and associated Patient Profile were found to be reliable and valid tools that facilitated assessment and enhancement of the holistic health status for people with musculoskeletal impairments. These tools identified barriers to achievement of holistic health, predicted by the Health Change Process Theory; facilitated the therapeutic process through a focus on issues meaningful to those receiving healthcare; aided treatment decision making; and enabled quantitative evidence-based evaluation of the efficacy of interventions. Moreover, the overall results have advanced psychological knowledge with implications for all fields of psychology involved in the study of people. The evidence of the research undertaken provides a basis for promoting knowledge and research of chronic healthcare delivery and a spiritually based conception of self and health. The QEHS and associated theories provide a tool and basis for investigations where people are experiencing traumatic, irreversible crises. However, the initial aims of further research should be to refine the QEHS and the associated Patient Profile to enable the use of theory and the QEHS across a diverse range of research populations and to investigate the applicability of these to facilitate the maintenance or achievement of a healthy self.

Consciousness: A Connectionist Perspective

Opie, Jonathan Philip January 1998 (has links)
Cognitive scientists seeking a computational account of consciousness almost universally opt for a process theory of some kind: a theory that explains phenomenal experience in terms of the computational processes defined over the brain's representational vehicles. But until recently cognitive science has been dominated by the classical computational theory of mind. Today there is a new player on the scene, connectionism, which takes its inspiration from a computational framework known as parallel distributed processing (PDP). It is therefore appropriate to ask whether connectionism has anything distinctive to say about consciousness, and in particular, whether it might challenge the dominance of process theories. I argue that connectionism has the resources to hazard a vehicle theory of consciousness. A vehicle theory places consciousness right at the focus of cognition by identifying it with the explicit representation of information in the brain. Classicism can't support such a theory because it is committed to the existence of explicit representations whose contents are not phenomenally conscious. The connectionist vehicle theory of consciousness aligns phenomenal experience with stable patterns of activation in neurally realised PDP networks. It suggests that consciousness is an amalgam of phenomenal elements, both sensory and non-sensory, and the product of a multitude of consciousness-making mechanisms scattered throughout the brain. This somewhat unorthodox picture is supported, I claim, by careful analysis of experience, and by the evidence of the neurosciences. One obstacle facing this account is the apparent evidence, both direct and indirect, for the activity of unconscious explicit representations in human cognition. I establish that much of the direct evidence for this thesis is open to doubt on methodological grounds. And studies that support the dissociation thesis indirectly, by way of an inference to the best explanation, are vulnerable to alternative connectionist explanations of the relevant phenomena. What is most significant about the connectionist vehicle theory of consciousness is not the fact that it's a connectionist theory of consciousness, but that it's a vehicle theory - an account which takes cognitive science into largely unexplored territory, but in so doing brings into clearer focus the issues with which any theory of consciousness must contend. / Thesis (Ph.D.)--Department of Philosophy, 1998.

Guided Wanderings: An A/r/tographic Inquiry into Postmodern Picturebooks, Bourdieusian Theory, and Writing

Pourchier, Adrianne Nicole M. 07 August 2012 (has links)
This dissertation is an a/r/tographic inquiry (Irwin & Springgay, 2008) that explores postmodern picturebooks and writing theory. Postmodern picturebooks have been described as texts that blur traditional literary boundaries and text-image relationships, while employing devices like metafiction and playfulness (Goldstone, 2002; Sipe, 2008). As meaning becomes more ambiguous, readers are positioned as co-constructors of meaning (Serafini, 2005). Research has shown students enjoy reading postmodern picturebooks and constructing meaningful transactions despite the complex nature of these texts (McGuire, Belfatti, & Ghiso, 2008; Pantaleo, 2004, 2007, 2008), but few have begun to explore how these texts are written. Therefore, I used a/r/tography (Irwin & Springgay, 2008) to theorize about the relationship between these texts and what it means to write. As a method of inquiry, a/r/tography is an arts-based approach to research that is interested in how artistic practices produce meaning and a/r/tographers use art to “construct the very ‘thing’ [they] are attempting to make sense of” (Springgay, 2008, p. 159). In this study, I wrote and illustrated a postmodern picturebook and interpreted how this experience generated understandings about what it means to write. In response to the process model of writing (Flower & Hayes, 1981), the data led to representations that offer new perspectives on contemporary writing theory, in particular, the interpretive, public, and situated nature of writing (Kent, 1999). As a result, I use theories of metaphor (Lakoff & Johnson, 1980/2003; Lakoff & Turner, 1989) to critique writing process theory (Elbow, 1973, 1981; Flower & Hayes, 1981) and propose that a/r/tographic inquiry creates openings for new possibilities within the post-process movement (Kent, 1999) by demonstrating how a writer’s evolving questions (Irwin & Springgay, 2008) relate to writing pedagogy.

Modeling Of Ground-borne Vibration From Underground Railway Systems

Sarigol, Melih 01 August 2007 (has links) (PDF)
Ground-borne vibration from underground rail vehicles is studied analytically. A previously developed model by J.A.Forrest and H.E.M.Hunt is modified to account for different track and vehicle models. The tunnel is modeled as infinite cylindrical shell surrounded by viscoelastic soil. The track is coupled to the tunnel with supports of complex stiffness. The rails, which are modeled as infinite Euler beams, are supported by discrete sleepers with regular spacing, and railpads with complex stiffness. A modified hysteretic damping model for moving loads is applied to soil. Linearized Hertzian contact spring is included between the wheel and the rail. The solution is obtained in frequency domain using random process theory. Effects of improvements in the model are graphically presented to enable comparison with the previously developed model and measurements from literature.
