Matter as Energy What Architects Need to Know
Current advances in technology and cyberspacecapacity coupled with emerging research in science education arecreating new opportunities to enhance architectural education inthe science and technology areas and prepare students foreffective collaboration with other stakeholders in the buildingindustry. The project described in this paper addresses the needfor the improvement of science and technology education andproposes that using advances in digital technology to engagestudents in interactive learning is a necessary step. One of themost promising and youngest applications of computertechnology has been in developing in educational games. Usingnew technologies to re-think the education of the architect in therelation to matter as energy reinforces the role of architecture inscience, technology and mathematics
A Linked Data Approach to Sharing Workflows and Workflow Results
A bioinformatics analysis pipeline is often highly elaborate, due to the inherent complexity of biological systems and the variety and size of datasets. A digital equivalent of the ‘Materials and Methods’ section in wet laboratory publications would be highly beneficial to bioinformatics, for evaluating evidence and examining data across related experiments, while introducing the potential to find associated resources and integrate them as data and services. We present initial steps towards preserving bioinformatics ‘materials and methods’ by exploiting the workflow paradigm for capturing the design of a data analysis pipeline, and RDF to link the workflow, its component services, run-time provenance, and a personalized biological interpretation of the results. An example shows the reproduction of the unique graph of an analysis procedure, its results, provenance, and personal interpretation of a text mining experiment. It links data from Taverna, myExperiment.org, BioCatalogue.org, and ConceptWiki.org. The approach is relatively ‘light-weight’ and unobtrusive to bioinformatics users
Usage, Impediments And Attitudes Towards Social Media In Uk Building Societies
The use of social media has revolutionized the internal and external communications and management of many businesses. This paper discusses the various social media platforms in the context of UK building societies. Many companies from the banking sector are utilizing social media, and in some this is outpacing traditional methods of marketing and internal communication. The main aim of this research is to identify the current social media usage trends and the barriers that limit the uptake of social media within the building society sector. The authors argue that strategic use of social media can prove useful and often rewarding. Preliminary empirical data from a survey and interviews support this analysis
The Parameterized Complexity of Centrality Improvement in Networks
The centrality of a vertex v in a network intuitively captures how important
v is for communication in the network. The task of improving the centrality of
a vertex has many applications, as a higher centrality often implies a larger
impact on the network or less transportation or administration cost. In this
work we study the parameterized complexity of the NP-complete problems
Closeness Improvement and Betweenness Improvement in which we ask to improve a
given vertex' closeness or betweenness centrality by a given amount through
adding a given number of edges to the network. Herein, the closeness of a
vertex v sums the multiplicative inverses of distances of other vertices to v
and the betweenness sums for each pair of vertices the fraction of shortest
paths going through v. Unfortunately, for the natural parameter "number of
edges to add" we obtain hardness results, even in rather restricted cases. On
the positive side, we also give an island of tractability for the parameter
measuring the vertex deletion distance to cluster graphs
Assessing Authentically – Learnings From Marketing Educators
This paper demonstrates the importance and role of authentic assessments, that replicate industry practice, within Higher Education marketing programmes. We answer the call from employers, that students need to gain much-needed employability skills, and we illustrate how such assessments can be created to enable the development of employability skills. We provide an overview of four case studies, to illustrate different forms of authentic assessments, the theory which was used to underpin the designs, the skills developed during the assessments, and the outcomes of the assessments. As we emerge from the COVID-19 pandemic, which forced a move to online assessments, it is timely that we reflect on the value of authentic assessments and adjust our practice
Citizen wellbeing and GDP: Towards more appropriate measures of Namibia\u27s success and progress
Developing nations like Namibia are aiming to industrialize much like developed nations and use the gross domestic product to measure their progress. However, this development path has been largely unsustainable. For Namibia to develop into a sustainable society, a different approach is needed. This study aimed to find entry points toward such an approach. Surveys were conducted in Windhoek, Namibia\u27s capital, to measure human well-being. Generally, as is expected in a developing country, well-being correlated positively along the income line. However, the indicators did illustrate that a more holistic measure would go a long way toward more effective development planning in Namibia. This study provided an entry point from which further work will be undertaken
Provider reimbursement following the Affordable Care Act
Decreasing healthcare expenditure has been one of the main objectives of the Affordable Care Act (ACA). To achieve this goal, the Centers for Medicare and Medicaid Services (CMS) has been tasked with experimenting with provider reimbursement methods in an attempt to increase quality, while decreasing costs. The purpose of this research was to study the effects of the ACA on physician reimbursement rates from CMS to determine the most cost effective method of delivering healthcare services. CMS has experimented with payment methods in an attempt to increase cost effectiveness. Medicare has offered shared cost savings incentives to reward quality care to both primary care providers and preventative services. CMS has determined fee-for- service payments obsolete, opting instead for a Value Based Purchasing (VBP) method of payment. Although a universal payment method has yet to be adopted, it has been evident that a VBP model and preventative care can be used to decrease healthcare expenditure
Chaotic temperature dependence at zero temperature
We present a class of examples of nearest-neighbour, boubded-spin models, in
which the low-temperature Gibbs measures do not converge as the temperature is
lowered to zero, in any dimension
Measuring the evolution of contemporary western popular music
Popular music is a key cultural expression that has captured listeners'
attention for ages. Many of the structural regularities underlying musical
discourse are yet to be discovered and, accordingly, their historical evolution
remains formally unknown. Here we unveil a number of patterns and metrics
characterizing the generic usage of primary musical facets such as pitch,
timbre, and loudness in contemporary western popular music. Many of these
patterns and metrics have been consistently stable for a period of more than
fifty years, thus pointing towards a great degree of conventionalism.
Nonetheless, we prove important changes or trends related to the restriction of
pitch transitions, the homogenization of the timbral palette, and the growing
loudness levels. This suggests that our perception of the new would be rooted
on these changing characteristics. Hence, an old tune could perfectly sound
novel and fashionable, provided that it consisted of common harmonic
progressions, changed the instrumentation, and increased the average loudness.Comment: Supplementary materials not included. Please see the journal

Superhyperfine interactions in inhomogeneously broadened paramagnetic centers observed via a hole-burned free induction decay
Superhyperfine interactions in inhomogeneously broadened paramagnetic centers are observed using a single high-turn-angle microwave pulse. The free induction signal that follows the hole-burning pulse exhibits oscillations that are distinct from the oscillatory free induction decay observable in some inhomogeneously broadened systems. It contains frequencies characteristic of the superhyperfine splittings, together with a zero frequency component. Experimental examples of the effect in both orientationally disordered (powdered) and structurally disordered (glassy) systems are presented and compared with the conceptually similar Fourier transform electron paramagnetic resonance detected nuclear magnetic resonance experiment, together with numerical simulations.
