Abstract:
The sharing economy gives rise to numerous new business models. A prominent novel one relates to coworking-spaces, where independent individuals and teams share spaces and amenities and engage in social interaction and information exchange. Yet the business models of such spaces are not well known. Our qualitative study identifies four types of business models design of coworking-spaces in China, where coworking-spaces have sharply increased in number and importance. We find four types of coworking-space business model configurations: efficiency-centered business model, user-centered business model, development-centered business model, and platform-centered business model, which exceed the prior conceptualization of business model themes. Especially, the platform-centered business model relates to innovation policy in China, facilitating mini-spatial innovation ecosystems.

Abstract:
We classify the moduli spaces of the four-dimensional topological half-flat gravity models by using the canonical bundle. For a K3-surface or T4, they describe an equivalent class of a trio of the Einstein-Kähler forms (the hyperkähler forms). We calculate the dimensions of these moduli spaces by using the Atiyah-Singer Index theorem. We mention the partition function and the possibility of the observables in the Witten-type topological half-flat gravity model case.

Abstract:
Relations between matrices representing non-relativistic and relativistic N-electron Hamiltonians in N-electron model spaces are analyzed. The model spaces are defined as the antisymmetric parts of products of the N-th Kronecker power of either a two-dimensional (the non-relativistic case) or four-dimensional (the relativistic case) spinor space and of an orbital (or configurational) space. The explicit relation between the matrices corresponding to the relativistic and non-relativistic cases is derived and its practical implications are briefly discussed.

Abstract:
Purpose Studies on color preferences for different types of spaces are scarce and show ambiguous results. This paper aims to present data about preferred colors for two work environments: the office and a meeting room, and two residential spaces: the living room and the bedroom. The authors also explore whether people with different personal characteristics of gender, age, education and type of person have different color preferences. Design/methodology/approach The data were collected by means of a questionnaire that was distributed among 1,077 Dutch people. Findings The color white was most frequently mentioned as the preferred color, by 32-44 per cent of all male respondents and 28-38 per cent of all female respondents, dependent on type of space. The choice “no color preference” rated high as well: by 11-22 per cent of men and 7-22 per cent of women. Preferred colors showed to be significantly different for different types of spaces, males and females, different age groups, level of education and type of person. Research limitations/implications The research took place in the Netherlands, so only Dutch color preferences have been collected. Due to the many influencing factors, only a selection of the conceptual model could be empirically tested. Practical implications Information about color preferences for different types of spaces can support clients, end users and (interior) architects to create environments that people like, which may influence peoples’ well-being in a positive way. It is suggested to apply colors in the built environment more like nature shows. Originality/value Until now, no information was available about color preferences for different types of spaces in connection with different types of personalities.

Abstract:
We consider the conformal properties of geometries described by higher-rank line elements. A crucial role is played by the conformal Killing equation (CKE). We introduce the concept of null-flat spaces in which the line element can be written as dsr=r!dζ1 … dζr. We then show that, for null-flat spaces, the critical dimension, for which the CKE has infinitely many solutions, is equal to the rank of the metric. Therefore, in order to construct an integrable conformal field theory in four dimensions we need to rely on fourth-rank geometry. We consider the simple model ℒ = ¼ Gμνλρ ∂μ ϕ ∂ν ϕ ∂λ ϕ ∂ρϕ and show that it is an integrable conformal model in four dimensions. Furthermore, the associated operators satisfy a Vir4 algebra.

Abstract:
It is shown how a conformal gravity and U (4) × U (4) Yang–Mills grand unification model in four dimensions can be attained from a Clifford gauge field theory in C-spaces (Clifford spaces) based on the (complex) Clifford Cl (4, C) algebra underlying a complexified four-dimensional space–time (eight real dimensions). Upon taking a real slice, and after symmetry breaking, it leads to ordinary gravity and the Standard Model in four real dimensions. A brief conclusion about the noncommutative star-product deformations of this Grand Unified Theory of gravity with the other forces of Nature is presented.

Abstract:
The purpose of this thesis is to investigate whether there is a correlation between the vision of the public library as expressed in “A new model for the public library” and how public libraries and its services are conveyed to newcomers to Sweden. Our two research questions inquire about the ways the public library and its services are conveyed and the challenges faced by public libraries in  communicating public libraries to newcomers? The method used for this study is semi-structured interviews with five public librarians working with multicultural issues at their workplaces. This study is theoretically grounded in the model for the public library proposed by Jochumsen, Rasmussen Hvenegaard and Skot-Hansen. The findings reveal that the model correlates quite well with how librarians describe their work in relation to newcomers.

Full text
Abstract:
A retrieval model describes the transformation of a query into a set of documents. The question is: what drives this transformation? For semantic information retrieval type of models this transformation is driven by the content and structure of the semantic models. In this case, Knowledge Organization Systems (KOSs) are the semantic models that encode the meaning employed for monolingual and cross-language retrieval. The focus of this research is the relationship between these meanings’ representations and their role and potential in augmenting existing retrieval models effectiveness. The proposed approach is unique in explicitly interpreting a semantic reference as a pointer to a concept in the semantic model that activates all its linked neighboring concepts. It is in fact the formalization of the information retrieval model and the integration of knowledge resources from the Linguistic Linked Open Data cloud that is distinctive from other approaches. The preprocessing of the semantic model using Formal Concept Analysis enables the extraction of conceptual spaces (formal contexts)that are based on sub-graphs from the original structure of the semantic model. The types of conceptual spaces built in this case are limited by the KOSs structural relations relevant to retrieval: exact match, broader, narrower, and related. They capture the definitional and relational aspects of the concepts in the semantic model. Also, each formal context is assigned an operational role in the flow of processes of the retrieval system enabling a clear path towards the implementations of monolingual and cross-lingual systems. By following this model’s theoretical description in constructing a retrieval system, evaluation results have shown statistically significant results in both monolingual and bilingual settings when no methods for query expansion were used. The test suite was run on the Cross-Language Evaluation Forum Domain Specific 2004-2006 collection with additional extensions to match the specifics of this model.

Abstract:
The rural libraries have a different context then the libraries in a more urban setting and therefore have a different way to organize and plan their activities. The aim of this bachelors thesis is to examine how librarians at libraries in the rural settings experience their activities and their role in the community. To acquire this information two questions are raised; “How are the activities at rural libraries described by the librarians?” and “How do the librarians view the libraries role in a rural setting?”. Answers to these questions will be achieved through semi-structured interviews, and their answers will be analysed with the use of the Four Spaces model. Four spaces is a model for viewing the activities in a library, and their goals. The collected data is then to be categorized according to four different terms: meetings, children and young adults, more personal service and challenges for a rural library. Many of the respondents expresses the use of the library as a meeting place and the important role that the libraries play in a small community in many different ways. One of the problems with working at a smaller library according to the librarians is that they have to prove to the management that their work is important, even in the smaller, rural settings.

Abstract:
The purpose of this thesis is to strengthen the state of knowledge and understanding of visitors use of the library area at Skellefteå city library based on the development of guidelines for how to work with the future library area based on Jochumsen, Hvenegaard Rasmussen, Skot-Hansen’s (2012) model of the four-spaces. The model contains four important spaces for libraries; the learning, the inspiration, the meeting and the performative space and all of them interact in an ideal library. The research question in this study is: How does the library in Skellefteå work as an inspiring, learning, meeting and performative space? And according to these questions, what kind of model should a new library have according to the four-spaces? The research method that is used in this study is Given and Leckie´s observational method the seating sweeps and complementing interviews with both visitors and one of the managing librarians. The result illustrated that the most common activity was the physical search for books among children, young adults and adults. For elderly people and especially men the most popular activity was reading the newspaper. These findings showed that the library is used primarily as learning and meeting space for adults but as an inspiring and performative space only for the younger children.

Abstract:
This paper presents an innovat ive cons t ruct ion of a probabilistic model for predicting chance situations. It describes the construction of a four phase model, derived from an intense qualitative analysis of the written responses of 94 mathematically talented middle school students to the probabilistic compound event problem: “How many doubles are expected when rolling two dice fifty times?” We found that the students’ comprehension process of compound event situations can be broken down into a four phase model: beliefs, subjective estimations, chance estimations and probabilistic calculations. The paper focuses on the development of the model over the course of the experiment, identifying the process the students underwent as they attempted to answer the question. We explain each phase as it was reflected in the students\'' rationalizations. All phases, including their definitions and students’ citations, will be presented in the paper. While not every student necessarily goes through all four phases, an awareness and understanding of them all allows for efficient, effective intervention during the learning process. We found that guidance and learning intervention helped shorten the preliminary phases, leading to more relative time spent on probabilistic calculations.

Abstract:
This doctoral thesis is devoted to investigate the problem of establishing connections between Domain Theory and the theory of fuzzy metric spaces, in the sense of Kramosil and Michalek, by means of the notion of a formal ball, and then constructing topological and computational models for (complete) fuzzy metric spaces. The antecedents of this research are mainly the well-known articles of A. Edalat and R. Heckmann [A computational model for metric spaces, Theoret- ical Computer Science 193 (1998), 53-73], and R. Heckmann [Approximation of metric spaces by partial metric spaces, Applied Categorical Structures 7 (1999), 71-83], where the authors obtained nice and direct links between Do- main Theory and the theory of metric spaces - two crucial tools in the study of denotational semantics - by using formal balls. Since every metric induces a fuzzy metric (the so-called standard fuzzy metric), the problem of extending Edalat and Heckmann's works to the fuzzy framework arises in a natural way. In our study we essentially propose two di erent approaches. For the rst one, valid for those fuzzy metric spaces whose continuous t-norm is the minimum, we introduce a new notion of fuzzy metric completeness (the so-called standard completeness) that allows us to construct a (topological) model that includes the classical theory as a special case. The second one, valid for those fuzzy metric spaces whose continuous t-norm is greater or equal than the Lukasiewicz t-norm, allows us to construct, among other satisfactory results, a fuzzy quasi-metric on the continuous domain of formal balls whose restriction to the set of maximal elements is isometric to the given fuzzy metric. Thus we obtain a computational model for complete fuzzy metric spaces. We also prove some new xed point theorems in complete fuzzy metric spaces with versions to the intuitionistic case and the ordered case, respec- tively. Finally, we discuss the problem of extending the obtained results to the asymmetric framework.<br>Ricarte Moreno, L. (2013).

Abstract:
Abstract Excitable cells are of vital importance in biology, and mathematical models have contributed significantly to understand their basic mechanisms. However, classical models of excitable cells are based on severe assumptions that may limit the accuracy of the simulation results. Here, we derive a more detailed approach to modeling that has recently been applied to study the electrical properties of both neurons and cardiomyocytes. The model is derived from first principles and opens up possibilities for studying detailed properties of excitable cells.We refer to the model as the EMI model because both the extracellular space (E), the cell membrane (M) and the intracellular space (I) are explicitly represented in the model, in contrast to classical spatial models of excitable cells. Later chapters of the present text will focus on numerical methods and software for solving the model. Also, in the next chapter, the model will be extended to account for ionic concentrations in the intracellular and extracellular spaces.

Abstract:
This learning paper presents an initial analysis of the emerging research to policy linkages within the Agricultural Policy Research in Africa (APRA) programme of the Future Agricultures Consortium, which is funded by the Foreign, Commonwealth &amp; Development Office (FCDO). APRA has an innovative monitoring, evaluation and learning approach known as the ‘Accompanied Learning on Relevance and Effectiveness’ (ALRE), which is being delivered by a small team of embedded evaluation specialists. This paper discusses how ALRE has applied the COM-B (Capability, Opportunity, Motivation and Behaviour) (Mayne 2018; Mayne 2016; Michie, van Stralen and West 2011) model of behaviour change to explore the interactions and influencing strategies between researchers and policymakers in the context of agricultural policy research in Africa. These insights have produced the Diamond of Influence, a new ALRE-adapted model, which applies each of the COM-B elements to discuss the different aspects of research to policy processes, drawing on examples of how researchers in each of the APRA focus countries (Ethiopia, Ghana, Malawi, Nigeria, Tanzania and Zimbabwe) are engaging in policy spaces.

Abstract:
The first-mile, last-mile problem is a significant deterrent for potential transit riders, especially in suburban neighborhoods with low density. Transit agencies have typically sought to solve this problem by adding parking spaces near transit stations and adding stops to connect riders to fixed-route transit. However, these measures are often only short-term solutions. In the last few years, transit agencies have tested whether new mobility services, such as ridehailing, ridesharing, and microtransit, can offer fast, reliable connections to and from transit stations. However, there is limited research that evaluates the potential impacts of these projects. Concurrently, there is growing interest in the future of automated vehicles (AVs) and the potential of AVs to solve this first-mile problem by reducing the cost of providing these new mobility services to promote access to transit. This paper expands upon existing research to model the simulate the travel and revenue impacts of a fleet of automated vehicles that provide transit access services in the San Francisco Bay Area offered over a range of fares. The model simulates a fleet of AVs for first-mile transit access at different price points for three different service models (door-to-door ridehailing and ridesharing and meeting point ridesharing services). These service models include home-based drop-off and pick-up for single passenger service (e.g., Uber and Lyft), home-based drop-off and pick-up for multi-passenger service (e.g., microtransit), and meeting point multi-passenger service (e.g., Via).
