The rise of co-creative consumers : user experience sharing behaviour in online communities

This thesis examines consumer initiated value co-creation behaviour in the context of convergent mobile online services using a Service-Dominant logic (SD logic) theoretical framework. It focuses on non-reciprocal marketing phenomena such as open innovation and user generated content whereby new viable business models are derived and consumer roles and community become essential to the success of business. Attention to customers. roles and personalised experiences in value co-creation has been recognised in the literature (e.g., Prahalad & Ramaswamy, 2000; Prahalad, 2004; Prahalad & Ramaswamy, 2004). Similarly, in a subsequent iteration of their 2004 version of the foundations of SD logic, Vargo and Lusch (2006) replaced the concept of value co-production with value co-creation and suggested that a value co-creation mindset is essential to underpin the firm-customer value creation relationship. Much of this focus, however, has been limited to firm initiated value co-creation (e.g., B2B or B2C), while consumer initiated value creation, particularly consumer-to-consumer (C2C) has received little attention in the SD logic literature. While it is recognised that not every consumer wishes to make the effort to engage extensively in co-creation processes (MacDonald & Uncles, 2009), some consumers may not be satisfied with a standard product, instead they engage in the effort required for personalisation that potentially leads to greater value for themselves, and which may benefit not only the firm, but other consumers as well. Literature suggests that there are consumers who do, and as a result initiate such behaviour and expend effort to engage in co-creation activity (e.g., Gruen, Osmonbekov and Czaplewski, 2006; 2007 MacDonald & Uncles, 2009). In terms of consumers. engagement in value proposition (co-production) and value actualisation (co-creation), SD logic (Vargo & Lusch, 2004, 2008) provides a new lens that enables marketing scholars to transcend existing marketing theory and facilitates marketing practitioners to initiate service centric and value co-creation oriented marketing practices. Although the active role of the consumer is acknowledged in the SD logic oriented literature, we know little about how and why consumers participate in a value co-creation process (Payne, Storbacka, & Frow, 2008). Literature suggests that researchers should focus on areas such as C2C interaction (Gummesson 2007; Nicholls 2010) and consumer experience sharing and co-creation (Belk 2009; Prahalad & Ramaswamy 2004). In particular, this thesis seeks to better understand consumer initiated value co-creation, which is aligned with the notion that consumers can be resource integrators (Baron & Harris, 2008) and more. The reason for this focus is that consumers today are more empowered in both online and offline contexts (Füller, Mühlbacher, Matzler, & Jawecki, 2009; Sweeney, 2007). Active consumers take initiatives to engage and co-create solutions with other active actors in the market for their betterment of life (Ballantyne & Varey, 2006; Grönroos & Ravald, 2009). In terms of the organisation of the thesis, this thesis first takes a „zoom-out. (Vargo & Lusch, 2011) approach and develops the Experience Co-Creation (ECo) framework that is aligned with balanced centricity (Gummesson, 2008) and Actor-to-Actor worldview (Vargo & Lusch, 2011). This ECo framework is based on an extended „SD logic friendly lexicon. (Lusch & Vargo, 2006): value initiation and value initiator, value-in-experience, betterment centricity and betterment outcomes, and experience co-creation contexts derived from five gaps identified from the SD logic literature review. The framework is also designed to accommodate broader marketing phenomena (i.e., both reciprocal and non-reciprocal marketing phenomena). After zooming out and establishing the ECo framework, the thesis takes a zoom-in approach and places attention back on the value co-creation process. Owing to the scope of the current research, this thesis focuses specifically on non-reciprocal value co-creation phenomena initiated by consumers in online communities. Two emergent concepts: User Experience Sharing (UES) and Co-Creative Consumers are proposed grounded in the ECo framework. Together, these two theorised concepts shed light on the following two propositions: (1) User Experience Sharing derives value-in-experience as consumers make initiative efforts to participate in value co-creation, and (2) Co-Creative Consumers are value initiators who perform UES. Three research questions were identified underpinning the scope of this research: RQ1: What factors influence consumers to exhibit User Experience Sharing behaviour? RQ2: Why do Co-Creative Consumers participate in User Experience Sharing as part of value co-creation behaviour? RQ3: What are the characteristics of Co-Creative Consumers? To answer these research questions, two theoretical models were developed: the User Experience Sharing Behaviour Model (UESBM) grounded in the Theory of Planned Behaviour framework, and the Co-Creative Consumer Motivation Model (CCMM) grounded in the Motivation, Opportunity, Ability framework. The models use SD logic consistent constructs and draw upon multiple streams of literature including consumer education, consumer psychology and consumer behaviour, and organisational psychology and organisational behaviour. These constructs include User Experience Sharing with Other Consumers (UESC), User Experience Sharing with Firms (UESF), Enjoyment in Helping Others (EIHO), Consumer Empowerment (EMP), Consumer Competence (COMP), and Intention to Engage in User Experience Sharing (INT), Attitudes toward User Experience Sharing (ATT) and Subjective Norm (SN) in the UESBM, and User Experience Sharing (UES), Consumer Citizenship (CIT), Relating Needs of Self (RELS) and Relating Needs of Others (RELO), Newness (NEW), Mavenism (MAV), Use Innovativeness (UI), Personal Initiative (PIN) and Communality (COMU) in the CCMM. Many of these constructs are relatively new to marketing and require further empirical evidence for support. Two studies were conducted to underpin the corresponding research questions. Study One was conducted to calibrate and re-specify the proposed models. Study Two was a replica study to confirm the proposed models. In Study One, data were collected from a PC DIY online community. In Study Two, a majority of data were collected from Apple product online communities. The data were examined using structural equation modelling and cluster analysis. Considering the nature of the forums, the Study One data is considered to reflect some characteristics of Prosumers and the Study Two data is considered to reflect some characteristics of Innovators. The results drawn from two independent samples (N = 326 and N = 294) provide empirical support for the overall structure theorised in the research models. The results in both models show that Enjoyment in Helping Others and Consumer Competence in the UESBM, and Consumer Citizenship and Relating Needs in CCMM have significant impacts on UES. The consistent results appeared in both Study One and Study Two. The results also support the conceptualisation of Co-Creative Consumers and indicate Co-Creative Consumers are individuals who are able to relate the needs of themselves and others and feel a responsibility to share their valuable personal experiences. In general, the results shed light on "How and why consumers voluntarily participate in the value co-creation process?. The findings provide evidence to conceptualise User Experience Sharing behaviour as well as the Co-Creative Consumer using the lens of SD logic. This research is a pioneering study that incorporates and empirically tests SD logic consistent constructs to examine a particular area of the logic – that is consumer initiated value co-creation behaviour. This thesis also informs practitioners about how to facilitate and understand factors that engage with either firm or consumer initiated online communities.

A holographic projection system with an electrically tuning and continuously adjustable optical zoom

A holographic projection system with optical zoom is demonstrated. By using a combination of a LC lens and an encoded Fresnel lens on the LCoS panel, we can control zoom in a holographic projector. The magnification can be electrically adjusted by tuning the focal length of the combination of the two lenses. The zoom ratio of the holographic projection system can reach 3.7:1 with continuous zoom function. The optical zoom function can decrease the complexity of the holographic projection system.

In-House Risk

Over the last thirty years or so, as the number of in-house counsel rose and their role increased in scope and prominence, increased attention has been given the various challenges these lawyers face under the ABA Model Rules of Professional Conduct, from figuring out who is the client the in-house lawyer represents, to navigating conflicts of interest, maintaining independence, and engaging in a multijurisdictional practice of law. Less attention, to date, has been given to business risk assessment, perhaps in part because that function appears to be part of in-house counsel’s role as a business person rather than as a lawyer. Overlooking the role of in-house counsel in assessing risk, however, is a risky proposition, because risk assessment constitutes for some in-house counsel a significant aspect of their role, a role that in turn informs and shapes how in-house counsel perform other more overtly legal tasks. For example, wearing her hat as General Counsel, a lawyer for the entity-client may opine and explain issues of compliance with the law. Wearing her hat as the Chief Legal Officer, however, the same lawyer may now be called upon as a member of business management to participate in the decision whether to comply with the law. After outlining some of the traditional challenges faced by in-house counsel under the Rules, this short essay explores risk assessment by in-house counsel and its impact on their role and function under the Rules. It argues that the key to in-house lawyers’ successful navigation of multiple roles, and, in particular, to their effective assessment of business risk is keen awareness of the various hats they are called upon to wear. Navigating these various roles may not be easy for lawyers, whose training and habits of mind often teach them to zoom in on legal risks to the exclusion of business risks. Indeed, law schools continue to teach law students “to think like a lawyer” and law firms, the historical breeding grounds for in-house counsel positions, in a world of increased specialization master the narrower contemplation of legal questions. Yet the present and future of in-house counsel practice demand of its practitioners the careful and gradual coming to terms, buildup and mastery of business risk analysis skills, alongside the cultivation of traditional legal risk analysis tools.

A hybrid molecular dynamics/fluctuating hydrodynamics method for modelling liquids at multiple scales in space and time

A new 3D implementation of a hybrid model based on the analogy with two-phase hydrodynamics has been developed for the simulation of liquids at microscale. The idea of the method is to smoothly combine the atomistic description in the molecular dynamics zone with the Landau-Lifshitz fluctuating hydrodynamics representation in the rest of the system in the framework of macroscopic conservation laws through the use of a single "zoom-in" user-defined function s that has the meaning of a partial concentration in the two-phase analogy model. In comparison with our previous works, the implementation has been extended to full 3D simulations for a range of atomistic models in GROMACS from argon to water in equilibrium conditions with a constant or a spatially variable function s. Preliminary results of simulating the diffusion of a small peptide in water are also reported.

What's in it for us? A case study research about micro sense making processes through the eyes of front line employees, during culture change implementation

Abstract How employees make sense of change is a very complex process. Recently, academics have neglected to research sense making activities in a micro culture implementation context, through the eyes of front line employees. In contrast to a macro view, a micro perspective limits researchers to only look at an individual, departmental or group level. By doing so, we can zoom in on the details of sense making processes that employees use in their daily work life. A macro (organisational) view is based on the notion that there is a general integrated culture that can be found in all organisational units and departments. It is assumed that culture can be researched by using the entire organisation as one single research entity. This thesis challenges this assumption. In case of planned change it is usually the management community who are in charge of the change intervention. Because of their formal hierarchical position, they have the power to abort or initiate change programs. It is perhaps therefore that researchers tend to be focused on the management community rather than on lower level organisational members, such as front line employees. Apart from the micro view, scholars also neglected to research culture change implementation through the eyes of front line employees. This thesis is an attempt to fill these two gaps that currently exists in academic change management publications. The main research question is therefore: From a micro point of view how do front-line employees make sense of the impact of culture change, during the implementation phase? This thesis starts with a literature review which exposes the two main gaps. The most important outcome of this review is that only 2% of the research articles dealt with culture implementation, through the eyes of front line employees. A conceptual research model is built on the integrated sense making theory of Weber and Manning (2001) and the micro variables of Raelin and Cataldo (2011). These theories emphasize elements of sense making in a daily working context. It is likely that front line employees can identify themselves with research elements such as tasks, skills practices, involvement and behaviour. Front line employees were selected, because as lower level organisational members they are usually the change recipients. They are further away from the change initiating scene (usually the management of an organisation) and form a potential sense making ‘hotspot’ that could provide new academic insights. In order to carry out the primary research, two case organisations were selected in the leisure industry. A participative case study research method was chosen. This meant that the researcher worked in the concerning departments of the case organisations. The goal was to observe and interview front line employees, while they were performing their jobs. The most important advantage of this approach is that the researcher temporarily becomes one with the organisation and is therefore able to acquire both formal and informal narratives that front line employees use during sense making activities. It was found that front line employees make sense of organisational change by using a practical approach. They make sense of the change program by carrying out new tasks, developing new skills and sharing best practices. The most noticeable conclusion was that sense making activities predominantly take place at an individual level in relation to change acceptance. Organisational members tend to create a mental equation in order to weigh the advantages against the disadvantages. They evaluate whether the concerning change program is beneficial to them or not. For future research a sense making scheme model is suggested that is based on two methods: an introspection and an action method.

Taming the terabytes : a human-centered approach to surviving the information deluge

A fear of imminent information overload predates the World Wide Web by decades. Yet, that fear has never abated. Worse, as the World Wide Web today takes the lion’s share of the information we deal with, both in amount and in time spent gathering it, the situation has only become more precarious. This chapter analyses new issues in information overload that have emerged with the advent of the Web, which emphasizes written communication, defined in this context as the exchange of ideas expressed informally, often casually, as in verbal language. The chapter focuses on three ways to mitigate these issues. First, it helps us, the users, to be more specific in what we ask for. Second, it helps us amend our request when we don't get what we think we asked for. And third, since only we, the human users, can judge whether the information received is what we want, it makes retrieval techniques more effective by basing them on how humans structure information. This chapter reports on extensive experiments we conducted in all three areas. First, to let users be more specific in describing an information need, they were allowed to express themselves in an unrestricted conversational style. This way, they could convey their information need as if they were talking to a fellow human instead of using the two or three words typically supplied to a search engine. Second, users were provided with effective ways to zoom in on the desired information once potentially relevant information became available. Third, a variety of experiments focused on the search engine itself as the mediator between request and delivery of information. All examples that are explained in detail have actually been implemented. The results of our experiments demonstrate how a human-centered approach can reduce information overload in an area that grows in importance with each day that passes. By actually having built these applications, I present an operational, not just aspirational approach.

J-Circos : an interactive Circos plotter

Circos plots are graphical outputs that display three dimensional chromosomal interactions and fusion transcripts. However, the Circos plot tool is not an interactive visualization tool, but rather a figure generator. For example, it does not enable data to be added dynamically, nor does it provide information for specific data points interactively. Recently, an R-based Circos tool (RCircos) has been developed to integrate Circos to R, but similarly, Rcircos can only be used to generate plots. Thus, we have developed a Circos plot tool (J-Circos) that is an interactive visualization tool that can plot Circos figures, as well as being able to dynamically add data to the figure, and providing information for specific data points using mouse hover display and zoom in/out functions. J-Circos uses the Java computer language to enable it to be used on most operating systems (Windows, MacOS, Linux). Users can input data into JCircos using flat data formats, as well as from the GUI. J-Circos will enable biologists to better study more complex chromosomal interactions and fusion transcripts that are otherwise difficult to visualize from next-generation sequencing data.

Visualization of complex biological systems: An immune response model using OpenGL

In this paper we present an update on our novel visualization technologies based on cellular immune interaction from both large-scale spatial and temporal perspectives. We do so with a primary motive: to present a visually and behaviourally realistic environment to the community of experimental biologists and physicians such that their knowledge and expertise may be more readily integrated into the model creation and calibration process. Visualization aids understanding as we rely on visual perception to make crucial decisions. For example, with our initial model, we can visualize the dynamics of an idealized lymphatic compartment, with antigen presenting cells (APC) and cytotoxic T lymphocyte (CTL) cells. The visualization technology presented here offers the researcher the ability to start, pause, zoom-in, zoom-out and navigate in 3-dimensions through an idealised lymphatic compartment.

Habitus realisation: Negotiating identities through Chinese looks and Chinese language

The increasing linguistic and cultural diversity of our contemporary world points to the salience of maintaining and developing Heritage Language of ethnic minority groups. The mutually constitutive effect between Heritage Language learning and ethnic identity construction has been well documented in the literature. Classical social psychological work often quantitatively structures this phenomenon in a predictable linear relationship. In contrast, poststructural scholarship draws on qualitative approaches to claim the malleable and multiple dynamics behind the phenomenon. The two schools oppose but complement each other. Nevertheless, both schools struggle to capture the detailed and nuanced construction of ethnic identity through Heritage Language learning. Different from the extant research, we make an attempt to ethno-methodologically unearth the nuisances and predicaments embedded in the reflexive, subtle, and multi-layered identity constructions through nuanced, inter-nested language practices. Drawing on data from the qualitative phase of a large project, we highlight some small but powerful moments abstracted from the interview accounts of five Chinese Australian young people. Firstly, we zoom in on the life politics behind the ‘seen but unnoticed’ stereotype that looking Chinese means being able to speak Chinese. Secondly, we speculate the power relations between the speaker and the listener through the momentary and inadvertent breaches of the taken-for-granted stereotype. Next, we unveil how learning Chinese has become an accountably rational priority for these young Chinese Australians. Finally, we argue that the normalised stereotype becomes visible and hence stable when it is breached – a practical accomplishment that we term ‘habitus realisation’.

Computational systems approach for drug target discovery

Importance of the field: The shift in focus from ligand based design approaches to target based discovery over the last two to three decades has been a major milestone in drug discovery research. Currently, it is witnessing another major paradigm shift by leaning towards the holistic systems based approaches rather the reductionist single molecule based methods. The effect of this new trend is likely to be felt strongly in terms of new strategies for therapeutic intervention, new targets individually and in combinations, and design of specific and safer drugs. Computational modeling and simulation form important constituents of new-age biology because they are essential to comprehend the large-scale data generated by high-throughput experiments and to generate hypotheses, which are typically iterated with experimental validation. Areas covered in this review: This review focuses on the repertoire of systems-level computational approaches currently available for target identification. The review starts with a discussion on levels of abstraction of biological systems and describes different modeling methodologies that are available for this purpose. The review then focuses on how such modeling and simulations can be applied for drug target discovery. Finally, it discusses methods for studying other important issues such as understanding targetability, identifying target combinations and predicting drug resistance, and considering them during the target identification stage itself. What the reader will gain: The reader will get an account of the various approaches for target discovery and the need for systems approaches, followed by an overview of the different modeling and simulation approaches that have been developed. An idea of the promise and limitations of the various approaches and perspectives for future development will also be obtained. Take home message: Systems thinking has now come of age enabling a `bird's eye view' of the biological systems under study, at the same time allowing us to `zoom in', where necessary, for a detailed description of individual components. A number of different methods available for computational modeling and simulation of biological systems can be used effectively for drug target discovery.

Switchable amplification of vibrational circular dichroism as a probe of local chiral structure

A new method to detect the vibrational circular dichroism (VCD) of a localized part of a chiral molecular system is reported. A local VCD amplifier was implemented, and the distance dependence of the amplification was investigated in a series of peptides. The results indicate a characteristic distance of 2.0±0.3 bonds, which suggests that the amplification is a localized phenomenon. The amplifier can be covalently coupled to a specific part of a molecule, and can be switched ON and OFF electrochemically. By subtracting the VCD spectra obtained when the amplifier is in the ON and OFF states, the VCD of the local environment of the amplifier can be separated from the total VCD spectrum. Switchable local VCD amplification thus makes it possible to “zoom in” on a specific part of a chiral molecule.

Kravsammanställning samt utvärdering avbildvisningsprogramför diagnostik inom telepatologi : En fallstudiemed SIV-metoden som tillvägagångssätt

De flesta har i sin närhet någon som drabbats av cancer och sjukdomsfallen har ökat genom åren. Den yrkesgrupp som ställer diagnos av denna sjukdom är patologer. Bristen på patologer är idagsläget stor och det finns därför ett behov av att finna effektiva lösningar för att möta denna brist och en ökande mängd patienter. För att digitalisera vävnadsproven som diagnostiseras, scannas dessa in med en glasscanner. Dessa digitala bildfiler kan sedan visas i ett bildvisningsprogram och delas digitalt mellan patologer på distans. Detta begrepp kallas för telepatologi. Studien utgår utifrån följande frågeställningar: Vilka krav är väsentliga och bör ingå i en utvärdering för bildvisningsprogram avsedda för diagnostik inom telepatologi? Vilket bildvisningsprogram är mest lämpat att implementeras i ett webbaserat system baserat på dessa väsentliga krav? Syftet med studien är att undersöka vilka krav som är väsentliga och bör ingå i en utvärdering av bildvisningsprogram avsedda för diagnostik inom telepatologi, samt att utföra en utvärdering av ett urval bildvisningsprogramvaror med hjälp av dessa krav. En fallstudie genomfördes med datainsamlingsmetoderna: intervjuer med två personer från studiens samarbetspartner CGM, Frågeformulär där Sveriges patologer var respondenter samt dokumentstudier för att samla in information gällande bildvisningsprogrammen. Studien tillämpar utvalda delar ur Anders G. Nilssons SIV-metod som tillvägagångsätt för att samla in krav samt för att göra ett urval av bildvisningsprogram som sedan utvärderas gentemot dessa krav. Resultaten av datainsamlingarna analyserades och ledde till ett kravdokument med väsentliga krav.Tre så kallade utslagsgivande faktorer bland dessa krav var att bildvisningsprogrammet måste vara webbaserat utan installation på klient, funktioner för in- och ut-zoomning samt panorering måste finnas. Utvärderingen av utvalda bildvisningsprogram visade slutligen att OpenSlide var mest lämpad att implementeras i ett webbaserat system.

Compreensão de natureza e formação do biólogo

Most knowledge and techniques developed by mankind since ancient times had the main purpose to study and understand the various phenomena of Nature. Science, like one of these narratives, works as a translation, transcribing what, is systematically observed. Within the set of transformations on the modern sciences, the dialogue with related areas became quite narrow and, occasionally, functional, and the dialogue with non-related areas, in turn, does not takes place by any matters. The focus of this research is the teaching of Biological Sciences, and the undergraduate courses as strategic places to disseminate a broad understanding of Nature, that broadens the conceptual relations between different disciplinary axes, previously fragmented. In order to do so, I take a four-way metaphorical approach as a methodological construction base. Three of them proposed by Joël de Rosnay, represented by artifacts: The Telescope, The Microscope and the Macroscope. And finally, a proposition that complements the approach, that i named The Naked Eye. In Telescope, which allows a more general construct of a phenomenon, I discuss the teaching of Biological Sciences in Brazil. In the microscope, which allows us to analyze in detail a scenario, I construct a rank of the major courses in biological sciences and propose a discussion on the understanding of nature on the undergraduate programs. In Macroscope, who allows, at the same time, zoom in and out to the phenomenon observed, I call for a transdisciplinary dialogue, based on the authors Ilya Prigogine, Basarab Nicolescu, Henri Atlan and Bruno Latour, which can certainly contribute to the curriculum of the Biologists training programs, that builds knowledge pertinent to a complex observation of Nature. I complete the set of the quaternary reading and understanding of the world from the Naked Eye, as the first strategy of perception in our species. For this, I invite the philosopher of Nature Chico Lucas da Silva as my interlocutor
