Exploring the effects of online team based learning and co regulated learning on students' development of computing skills
Venue: Interact. Learn. Environ.

As more and more educational institutions are providing online courses, it is necessary to design effective teaching methods integrated with technologies to benefit both teachers and students. The researcher in this study designed innovative online teaching methods of team based learning (TBL) and co regulated learning (CRL) to improve students' computing skills. The participants in this study were 124 undergraduates from three classes taking a compulsory course titled "Applied Information Technology: Data Processing." There were three blended classes involved in this empirical study. The first group (EG1) which received the treatment of online TBL and CRL, and the second group (EG2) which received the treatment of online TBL only, were the experimental groups. The last group, which received the traditional teaching method, served as the control group. Before the experiment started, the author conducted a pretest to confirm that the differences of students' computing skills among the three groups were not significant at the beginning of the course. Based on the analysis of the post test, the results indicate that students who received the intervention of online CRL had significantly better computing skills for using Excel by semester end than those without. However, the intervention of online TBL did not contribute to better learning effects in this study. Based on the findings in this study, the author points out implications for teachers, schools, and educators, particularly for those responsible for courses focusing on solving ill structured problems and those students who have typically received traditional didactic pedagogy for many years.

A multi method review of home based chemotherapy.
Venue: European journal of cancer care

This study summarises research and practice based evidence on home based chemotherapy, and explores existing delivery models. A three pronged investigation was conducted consisting of a literature review and synthesis of 54 papers, a review of seven home based chemotherapy programmes spanning four countries, and two case studies within the Canadian province of Ontario. The results support the provision of home based chemotherapy as a safe and patient centred alternative to hospital and outpatient based service. This paper consolidates information on home based chemotherapy programmes including services and drugs offered, patient eligibility criteria, patient views and experiences, delivery structures and processes, and common challenges. Fourteen recommendations are also provided for improving the delivery of chemotherapy in patients' homes by prioritising patient centredness, provider training and teamwork, safety and quality of care, and programme management. The results of this study can be used to inform the development of an evidence informed model for the delivery of chemotherapy and related care, such as symptom management, in patients' homes.
Correlation feature selection and mutual information theory based quantitative research on meteorological impact factors of module temperature for solar photovoltaic systems

The module temperature is the most important parameter influencing the output power of solar photovoltaic (PV) systems, aside from solar irradiance. In this paper, we focus on the interdisciplinary research that combines the correlation analysis, mutual information (MI) and heat transfer theory, which aims to figure out the correlative relations between different meteorological impact factors (MIFs) and PV module temperature from both quality and quantitative aspects. The identification and confirmation of primary MIFs of PV module temperature are investigated as the first step of this research from the perspective of physical meaning and mathematical analysis about electrical performance and thermal characteristic of PV modules based on PV effect and heat transfer theory. Furthermore, the quantitative description of the MIFs influence on PV module temperature is mathematically formulated as several indexes using correlation based feature selection (CFS) and MI theory to explore the specific impact degrees under four different typical weather statuses named general weather classes (GWCs) Case studies for the proposed methods were conducted using actual measurement data of a 500 kW grid connected solar PV plant in China. The results not only verified the knowledge about the main MIFs of PV module temperatures, more importantly, but also provide the specific ratio of quantitative impact degrees of these three MIFs respectively through CFS and MI based measures under four different GWCs.
Street Politics: Street Vendors and Urban Governance in China
Venue: The China Quarterly

Conflicts between urban street vendors and city regulators have become a common urban sight in Chinese cities today. This paper considers how visions of modern urban streets and sidewalks have helped to generate increasingly restrictive policies on street vending and spurred new forms of urban regulation and policing. While mostly an everyday routine of Chinese city life, the resulting vendor chengguan conflicts dramatize state power in public and carry the latent danger of crowd violence in response. In particular, aggressive policing of highly visible city streets can at times produce a volatile "politics of the street" involving episodes of vendor resistance and even dramatic expressions of bystander solidarity which challenge these street level expressions of state power.

The Changing Landscape of Condominium Laws and Urban Governance in China

China, as a transitional economy, meets its challenges by devising private law reforms while considering their potential conflict with prevailing cultural orientations and institutional settings. The academic discourse shows the multiple benefits that homeowner associations (HOAs) can offer. Yet, all of these proposed benefits are contingent on HOAs functioning well. What kind of law should help avoid dysfunctional practices and resolve effectively the disputes in the Chinese condominium context? In order to answer this, the initial step is to identify the problems pertaining to condominium governance in the Chinese context. To this end, this chapter aims to depict the institutional design and operational implementation of condominium governance in China. First, it traces the evolution of condominium ownership in China. It then provides a general overview of the current statutory framework relating to condominium ownership. Subsequently, some practical difficulties are illustrated in respect of demarcation between individual units and common property, pre sale of apartments, and allocation of participation quota. Furthermore, issues involving collective management of common property and the local government's role in shaping the property relations among stakeholders are addressed. A micro analysis of local condominium rules at the local level is highlighted to allay malpractice and developer overreaching. Finally, the chapter concludes on how to capture the dynamic property relations among key actors and between rules, norms, and cultural changes.
Big Events and Urban Governance in China

In 2009, on short notice, the City of Nanjing decided to bid for the Youth Olympics in 2014. This was done in order to demonstrate that the former capital city of China could compete with economically thriving city regions of the country, such as Shanghai, Beijing, Chongqing or Guangzhou. The event was driven by the local government in order to create opportunities for new urban development in a slowly stagnating property market and to seek Central Government support for accelerating the development of public infrastructure. In 2009, the decision went to Nanjing. With the support of the Central Government, Nanjing could attract the event to the city. The paper will explore whether the expectations of the local government came true. It will describe how the city prepared for the event and what challenges the city had to face to arrange the grounds for the event. It will also assess the positive and negative implications of using such an event for urban development. Some general conclusions will be drawn at the end, i.e. whether eventdriven urban development in China is unavoidable as a means of profiling cites in times of globalization; and to what extent such events have an impact on city governance in Chinese cities.
Qualitative Data Techniques In Social Sciences

Focus group discussions are an exploratory research tool, thus a structured group used to explore people's thoughts and feelings and obtain detailed information about a particular topic or issue. Focus group discussions lasts from one hour and a half to two hours, longer than this and the discussion loses momentum. If the discussion is well managed, it allows deep seated feelings on a subject to emerge naturally. A focus group discussion is an in depth session in which a small number of people usually eight to twelve from the target population, under the guidance of a facilitator (moderator) discuss topics of importance for a particular study or project. In nature focus group discussions are a method in which the topics covered are flexible and the discussion starts with more general issues and slowly flows into more specific ones. This book is going to focus on highlighting the merits as well as the demerits of focus group discussions as a data collection instrument in monitoring and evaluation.
Semantic User Profiles: Learning Scholars' Competences by Analyzing their Publications

Semantic publishing generally targets the enhancement of scientific artifacts, such as articles and datasets, with semantic metadata. However, smarter scholarly applications also require a better model of their users, in order to understand their interests, tasks, and competences. These are generally captured in so called user profiles. We investigate a number of existing linked open data (LOD) vocabularies and propose a description of scientists' competences in LOD format. To avoid the cold start problem, we suggest to automatically populate these profiles based on the publications (co )authored by users, which we hypothesize reflect their research competences. Towards this end, we developed the first complete, automated workflow for generating semantic user profiles by analyzing full text research articles through natural language processing. We evaluated our system with a user study on ten researchers from two different groups, resulting in mean average precision (MAP) of up to 92% We also analyze the impact of semantic zoning of research articles on the accuracy of the resulting profiles. Finally, we demonstrate how these semantic user profiles can be applied in a number of use cases, including article ranking for personalized search and finding scientists competent in a topic e.g. to find reviewers for a paper.
Attitude estimation with feedback particle filter
Venue: 2016 IEEE 55th Conference on Decision and Control (CDC)

This paper presents theory, application, and comparisons of the feedback particle filter (FPF) algorithm for the problem of attitude estimation. The paper builds upon our recent work on the exact FPF solution of the continuous time nonlinear filtering problem on matrix Lie groups. In this paper, the details of the FPF algorithm are presented for the problem of attitude estimation a nonlinear filtering problem on SO(3) Quaternions are employed for computational purposes. The algorithm requires a numerical solution of the filter gain function, and two methods are applied for this purpose. Comparisons are also provided between the FPF and some popular algorithms for attitude estimation, including the multiplicative EKF, the unscented quaternion estimator, the invariant EKF, and the invariant ensemble Kalman filter. Simulation results are presented that help illustrate the comparisons.
Feedback Particle Filter for a Continuous Time Markov Chain
Venue: IEEE Transactions on Automatic Control

This technical note extends the feedback particle filter (FPF) methodology and algorithms to the problem of filtering a continuous time Markov chain. The main contribution is the development of a feedback control based transformation of the Wonham filter, where the control input is realized via a time modulated Poisson counter process. A complete characterization of the feedback mechanism that defines the FPF is obtained, which leads to tractable algorithms for the nonlinear filtering problem even for large state spaces. Numerical examples are introduced to help illustrate the application of these techniques.

The bacterial cell envelope as delimiter of anti infective bioavailability An in vitro permeation model of the Gram negative bacterial inner membrane.
Venue: Journal of controlled release official journal of the Controlled Release Society

Gram negative bacteria possess a unique and complex cell envelope, composed of an inner and outer membrane separated by an intermediate cell wall containing periplasm. This tripartite structure acts intrinsically as a significant biological barrier, often limiting the permeation of anti infectives, and so preventing such drugs from reaching their target. Furthermore, identification of the specific permeation limiting envelope component proves difficult in the case of many anti infectives, due to the challenges associated with isolation of individual cell envelope structures in bacterial culture. The development of an in vitro permeation model of the Gram negative inner membrane, prepared by repeated coating of physiologically relevant phospholipids on Transwell(r) filter inserts, is therefore reported, as a first step in the development of an overall cell envelope model. Characterization and permeability investigations of model compounds as well as anti infectives confirmed the suitability of the model for quantitative and kinetically resolved permeability assessment, and additionally confirmed the importance of employing bacteria specific base materials for more accurate mimicking of the inner membrane lipid composition both advantages compared to the majority of existing in vitro approaches. Additional incorporation of further elements of the Gram negative bacterial cell envelope could ultimately facilitate model application as a screening tool in anti infective drug discovery or formulation development.
In vivo and in vitro protein digestibility in juvenile bagrid catfish Mystus nemurus (Cuvier and Valenciennes 1840) fed soybean meal based diets

In vivo and in vitro protein digestibility of 0% to 60% soybean meal protein (SBM) substitution from fishmeal protein was conducted for bagrid catfish Mystus nemurus juveniles. Seven experimental diets containing 35% protein and 15% lipid were fed to bagrid catfish to determine the in vivo protein digestibility. In vitro methods were determined using pH stat, pH shift, spectrophotometric assay and sodium dodecyle sulphate polyacrylamide gel electrophoresis (SDS PAGE) with different enzyme mixtures (crude intestinal extract of bagrid catfish, Lazo 1 enzyme, Hsu 3 enzyme, Saterlee 4 enzyme) In vivo and in vitro protein digestibility decreased with increased SBM protein substitution with highest tolerance level of 10% (in vivo) pH stat and pH drop methods showed the highest degree of hydrolysis (DH) and relative protein digestibility (RPD) using Saterlee 4 enzyme system. However, pH stat method showed highest correlations (r2 0.9263) with the in vivo results using crude intestinal enzyme extract compared to other enzyme systems. The highest correlation of the in vitro methods using crude intestinal enzyme extracts of bagrid catfish was determined using spectrophotometric assay (r2 0.9284) followed by pH stat (r2 0.9263) SDS PAGE (r2 0.8348) and pH drop (r2 0.6777) All the in vitro methods tested are suitable to rapidly determine protein digestibility for bagrid catfish except for pH drop.
Incremental Innovation Effects on Consumer Perception

Until today, research is focusing mostly on management and marketing of radical innovations. This seems surprising as companies nowadays mostly compete with incremental innovations (e.g. successive generations of mobile devices, notebooks, etc. and a crucial portion of the company's revenues and yields are due to product generation sales. To extend the knowledge of incremental innovations, the purpose of this research was to explore in detail about the consumer perception of incremental innovations. The main question to answer was, if consumers have positive or negative feelings regarding incremental innovations. The research also examined if the perception of the incremental innovations will affect the market success of a product or not. This research explored secondary, if consumers always expect radical innovations from manufacturers. The results of this research indicated, that it can be assumed, that consumers have a positive perception regarding incremental innovations. It could not been shown with scientific proof that if the perception of the incremental innovation tend to be perceived as radical innovative, the perception will influence the market success of a product, but with the used non scientific approach, it could be shown that it can be assumed. The other contribution of this study was to gain knowledge if consumer always expects from producers radical innovations. The results of this research indicates, that consumer not always expect radical innovations from manufacturer. Incremental innovations are also accepted from consumers regarding the product development. It can be assumed that incremental and radical innovations are ranking on the same level of positive perception from the consumer.
Digital library interoperability at high level of abstraction
Venue: Future Gener. Comput. Syst.

Digital Library (DL) are the main conduits for accessing our cultural heritage and they have to address the requirements and needs of very diverse memory institutions, namely Libraries, Archives and Museums (LAM) Therefore, the interoperability among the Digital Library System (DLS) which manage the digital resources of these institutions is a key concern in the field.DLS are rooted in two foundational models of what a digital library is and how it should work, namely the DELOS Reference Model and the Streams, Structures, Spaces, Scenarios, Societies (5S) model. Unfortunately these two models are not exploited enough to improve interoperability among systems.To this end, we express these foundational models by means of ontologies which exploit the methods and technologies of Semantic Web and Linked Data. Moreover, we link the proposed ontologies for the foundational models to those currently used for publishing cultural heritage data in order to maximize interoperability.We design an ontology which allows us to model and map the high level concepts of both the 5S model and the DELOS Reference Model. We provide detailed ontologies for all the domains of such models, namely the user, content, functionality, quality, policy and architectural component domains in order to make available a working tool for making DLS interoperate together at a high level of abstraction. Finally, we provide a concrete use case about digital annotation of illuminated manuscripts to show how to apply the proposed ontologies and illustrate the achieved interoperability between the 5S and DELOS Reference models. Foundational models for digital libraries.Interoperability among digital library systems and possible approaches.Unifying semantic model and ontology for high level interoperability among digital library systems.In depth analysis of the user, content, functionality and quality domains in digital libraries.Concrete use case on annotation of illuminated manuscripts to illustrate how to apply the proposed methodology.
Coded skeleton: programmable bodies for shape changing user interfaces
Venue: SIGGRAPH Posters

We propose novel design method to fabricate user interfaces with mechanical metamaterial called Coded Skeleton. The Coded Skeleton is combination of shape memory alloys (SMA) and 3 D printed bodies, and it has computationally designed structure that is flexible in one deformation mode but is stiff in the other modes. This property helps to realize materials that automatically deform by a small and lightweight actuator such as SMA. Also it enables to sense user inputs with the resistance value of SMA. In this paper, we propose shape changing user interfaces by integrating sensors and actuators as Coded Skeleton. The deformation and stiffness of this structure is computationally designed and also controllable. Further, we propose interactions and applications with user interfaces fabricated using our design method.
