Multimedia repositories in learning and teaching – lessons from the MIDESS Project

The MIDESS project brought together 4 UK universities to explore the management of digitised content through the development of a digital repository infrastructure. The project focused on multimedia materials in particular and looked at how support can be provided for their use in a learning and research context and how resources can be shared both within and between institutions. Three repositories were implemented, using Fedora, DSpace and Digitool respectively. Material suitable for ingest was identified and the dialogue with academic partners in each institution helped clarify not only the complexity of the interactions required but also the value of the repository in supporting learning, teaching and research. Having established a repository platform within each institution, the project then explored how multimedia content could be exchanged and shared between the repositories, using OAI-PMH and METS as transport mechanisms. This paper will summarise the project’s main findings. In particular, it will address how a multimedia repository might fit into the information architecture of the university, the likely requirements for integration into an inter-institutional or national framework and some of the obstacles which can impede such integration. Scenarios will be presented illustrating how student learning can benefit from such a repository within a research-intensive university and the relationship between the repository and the VLE will be discussed

Thermodynamic and Kinetic Properties of Materials for Next-Generation Rechargeable Batteries from First-Principles.

To break out of small electronics and into vehicles, rechargeable battery technology needs to overcome several obstacles. First, safety issues plague the usage of liquid electrolytes in traditional Li-ion battery systems. Secondly, alternative elements to Li would be more earth-abundant as well as potentially have higher capacities. With these factors in mind, we will discuss thermodynamic and kinetic properties from first-principles calculations surrounding three next-generation materials for rechargeable batteries: a solid electrolyte, Li3OCl, for use in Li-ion batteries. a magnesium battery electrode (MgTiS2), and a sodium battery electrode (NaCoO2). First, we explore diffusion in Li3OX (X=Cl, Br), a superionic conductor with experimental conductivities on the order of 1 mS/cm. These compounds, which have an anti-perovskite crystal structure, have potential applications as solid electrolytes in Li-ion batteries to replace the currently-employed liquid electrolytes. We identify a low-barrier three-atom hop mechanism involving Li interstitial dumbbells. This hop mechanism is facile within the (001) crystallographic planes of the perovskite crystal structure and is evidence for the occurrence of concerted motion, similar to ionic transport in other solid electrolytes. Our first-principles analysis of phase stability predicts that antiperovskite Li3OCl (Li3OBr) is metastable relative to Li2O and LiCl (LiBr) at room temperature. Second, we examine the thermodynamic and kinetic properties of MgTiS2 and compare it to its well-known analog, LiTiS2 in order to better understand the difficulties obtaining facile diffusion in Mg-ion batteries. We show that although thermodynamically, the two systems are incredibly similar, the extra electron that Mg has over Li hinders diffusion immensely. Thirdly, we briefly investigate the spinel NaCoO2. Unlike any other spinel structure where intercalating species first occupy all tetrahedral sites then proceed to occupy octahedral sites, with sodium, both octahedral and tetrahedral sites are filled at various compositions leading to some unique thermodynamic and kinetic results.PhDMaterials Science and EngineeringUniversity of Michigan, Horace H.

Non-Pharmacological Management of Behavioral Symptoms in Dementia Residents

The World Health Organization explains that 50 million people are diagnosed with dementia globally (2017). In dementia patients, agitation is the most common reported symptom (Livingston et al., 2017). Interventions for agitation are crucial in promoting quality of life, providing a safe environment, and reducing caregiver burden. Many residents within long-term care facilities display forgetfulness and many have a diagnosis of dementia. Nursing Assistant Certification programs provide little to no education on non-pharmacological techniques to de-escalate agitated residents (C. Taylor, personal communication, February 21, 2018). The focus is to provide an education tool for Certified Nursing Assistants (CNAs) within long-term care facilities to obtain knowledge on how to note verbal and nonverbal signs of agitation, find the root cause of the agitation, and being able to implement de-escalation techniques such as music therapy, massage, and reducing environmental stimulation etc. A survey tool was used to evaluate the receptiveness of the educational powerpoint and a case study that provided opportunity to work through a real clinical scenario of an agitated resident diagnosed with dementia. The goal of this project is to better equip unlicensed nursing personnel at long-term care facilities with a knowledge base and educational tools on techniques for staff to implement in provision of care for agitated dementia residents

Ab initio structure search and in situ 7Li NMR studies of discharge products in the Li-S battery system.

The high theoretical gravimetric capacity of the Li-S battery system makes it an attractive candidate for numerous energy storage applications. In practice, cell performance is plagued by low practical capacity and poor cycling. In an effort to explore the mechanism of the discharge with the goal of better understanding performance, we examine the Li-S phase diagram using computational techniques and complement this with an in situ (7)Li NMR study of the cell during discharge. Both the computational and experimental studies are consistent with the suggestion that the only solid product formed in the cell is Li2S, formed soon after cell discharge is initiated. In situ NMR spectroscopy also allows the direct observation of soluble Li(+)-species during cell discharge; species that are known to be highly detrimental to capacity retention. We suggest that during the first discharge plateau, S is reduced to soluble polysulfide species concurrently with the formation of a solid component (Li2S) which forms near the beginning of the first plateau, in the cell configuration studied here. The NMR data suggest that the second plateau is defined by the reduction of the residual soluble species to solid product (Li2S). A ternary diagram is presented to rationalize the phases observed with NMR during the discharge pathway and provide thermodynamic underpinnings for the shape of the discharge profile as a function of cell composition.Fellowship support to KAS from the ConvEne IGERT Program of the National Science Foundation (DGE 0801627) is gratefully acknowledged.

Calcium-ion batteries: current state-of-the-art and future perspectives

Recent developments in rechargeable battery technology have seen a shift from the well-established Li-ion technology to new chemistries to achieve the high energy density required for extended range electric vehicles and other portable applications, as well as low-cost alternatives for stationary storage. These chemistries include Li–air, Li–S, and multivalent ion technologies including Mg2+, Zn2+, Ca2+, and Al3+. While Mg2+ battery systems have been increasingly investigated in the last few years, Ca2+ technology has only recently been recognized as a viable option. In this first comprehensive review of Ca2+ ion technology, the use of Ca metal anodes, alternative alloy anodes, electrolytes suitable for this system, and cathode material development are discussed. The advantages and disadvantages of Ca2+ ion batteries including prospective achievable energy density, cost reduction due to high natural abundance, low ion mobility, the effect of ion size, and the need for elevated temperature operation are reviewed. The use of density functional theory modeling to predict the properties of Ca-ion battery materials is discussed and the extent to which this approach is successful in directing research into areas of promise is evaluated. To conclude, a summary of recent achievements and evaluates areas for future research efforts is presented
