description: We consider a non-standard totalisation functor to produce a cochain complex from a given double complex: instead of sums or products, totalisation is defined via truncated products of modules. We give an elementary proof of the fact that a double complex with exact rows (resp, columns) yields an acyclic cochain complex under totalisation using right (resp, left) truncated products. As an application we consider the algebraic mapping torus T(h) of a self map h of a cochain complex C. We show that if C consists of finitely presented modules then T(h) has trivial negative Novikov cohomology; if in addition h is a quasi-isomorphism, then T(h) has trivial positive Novikov cohomology as well. As a consequence we obtain a new proof that a finitely dominated cochain complex over a Laurent polynomial ring has trivial Novikov cohomology.

description: In Malaysia, there are different understandings of the term 'design', where it appears to be perceived by many as being about the artistic beauty and function of the object created, rather than the process leading to it. This is evident through the review of literature, and major companies’ R&D activities, where the demand in the Malaysian market is about the finished products, rather than the whole design process and the values behind the creation. The issue arises when there is no significant effort by the designers towards embedding the society’s values or cultural elements into their design products. Then comes the question of what is the role of designers here? Can Malaysian designers succeed in designing Malaysian character products that portray the identity of the nation? Dismissed as disposable, cultural uniqueness and its values haven’t been explicitly addressed in most Malaysian design approaches, let alone in the academic writing, which represents a severe omission of past research and current design scenarios in Malaysia. The objectives of this study were: investigating the relationship of design to culture; reviewing current efforts by Malaysians to produce Malaysian identity products; concluding the value and significance of culture as product identity; and making recommendations of a suitable design process in developing Malaysian identity design. These have been achieved through interviews with stakeholders; conducting case studies to strengthen the knowledge of local culture; and making recommendations as to how future designers can succeed in designing Malaysian identity products through focus group studies. A more precise view of the importance of Malaysia having a strong identity in their designed products by incorporating the cultural values of the societies has been established through these processes. To reflect these issues, this study has selected taxi design as the case study to justify the importance of identity in design, based on arguments in the literature. It has become self-evident that there is a need for more collaborative and coherent efforts from various parties to ensure that Malaysian designers will succeed in developing Malaysian identity products in the future.

title: An analysis of the effects of the oil industry on economic development in Nigeria
Creators: name: Onosode, Inerhunwa Christopher
Publisher: name: University of Kent
Year: 2021

description: This thesis examines the direct and indirect effects of the oil industry on economic development in Nigeria between 1960 and 1995. Three main empirical issues are addressed. Firstly, the thesis questions the relevance of orthodox models of Dutch Disease to Nigeria by testing the effects of variables such as the real price of oil and government real investment expenditures in the oil sector on sectoral output, and investment and labour demand. Secondly, the effect of a smaller oil sector on the economy in general and on the manufacturing sector in particular is analysed. Thirdly, the effects of the balance of payments on the economy under both a fixed and a floating exchange rate system are examined. This study is in two parts. Part I which comprises Chapters One to Four provides the background and descriptive accounts of the thesis. Chapter One is an introductory chapter. In Chapter Two, a description of the Nigerian economy and macroeconomic policy developments from 1960 to 1995 is provided. In Chapter Three, a critical examination of the oil sector is carried out including an account of tile direct physical and environmental effects. Chapter Four provides a theoretical and empirical overview of the literature on Dutch Disease and related macroeconomic sectoral models. Part II comprises the core empirical chapters. Tn Chapter Five, a dynamic multi sectoral Dutch Disease macroeconomic model is developed. In this chapter, three variants are considered, a world price model, an exogenous exchange rate model and a balance of payments constrained growth rate model. The chapter also discusses a number of econometric issues in the context of simultaneous equation models. In Chapter Six, the model is estimated and parameter estimates examined. Tn Chapter Seven, a critical examination of the Nigerian manufacturing sector is carried out which is based on the estimated Dutch Disease macro model under both a floating and a fixed exchange rate system and on a constructed traded goods index. An account of Nigeria's industrial poiicy developments since 1960 is also given. In Chapter Eight, the model is used for examining the effects of the balance of payments oti tile Nigerian economy under a floating exchange rate system. In this chapter, various theoretical models of exchange rate determination are used to calculate the Nigerian Naira exchange rate. A detailed account of exchange rate and related macroeconomic policy developments in Nigeria since 1914 is contained in an appendix. The summary and conclusions of the study are contained in Chapter Nine.

description: The nuclear symmetry energy $E_{sym}(ρ)$ and its density slope $L(ρ)$ can be decomposed analytically in terms of the single-nucleon potential in isospin asymmetric nuclear matter. Using three popular nuclear effective interaction models which have been extensively used in nuclear structure and reaction studies, namely, the isospin and momentum dependent MDI interaction model, the Skyrme Hartree-Fock approach and the Gogny Hartree-Fock approach, we analyze the contribution of different terms in the single-nucleon potential to the $E_{sym}(ρ)$ and $L(ρ)$. Our results show that the observed different density behaviors of $E_{sym}(ρ)$ for different interactions are essentially due to the variation of the symmetry potential $U_{sym,1}(ρ,k)$. Furthermore, we find that the contribution of the second-order symmetry potential $U_{sym,2}(ρ,k)$ to the $L(ρ)$ generally cannot be neglected. Moreover, our results demonstrate that the magnitude of the $U_{sym,2}(ρ,k)$ is generally comparable with that of $U_{sym,1}(ρ,k)$, indicating the second-order symmetry potential $U_{sym,2}(ρ,k)$ may have significant corrections to the widely used Lane approximation to the single-nucleon potential in extremely neutron(proton)-rich nuclear matter.

Determinants of health outcomes in switching to electric bicycles

Publisher: name: University of British Columbia
Year: 2012

description: Electric bicycles have grown rapidly in popularity in recent years, but with little examination of their health effects. We explore their main health effects for different categories of riders in different contexts. Relative risks of mortality were calculated for people transitioning to electric bicycles from cars and bicycles, for 7.5km weekday commutes. Three health impact mechanisms were considered: collisions, air pollution, and physical exercise. Results were evaluated for women and men of different ages and riding style in urban Netherlands. The calculations were then applied to four other countries with significant contextual differences. Changes in exercise level dominated health outcomes in most cases. Even minimal pedaling exertion during commuting brought substantial health benefits. Collision risks were important for young riders relative to the low mortality hazards they otherwise face. Air pollution impacts were small except in the worst air quality case. The combined health effects indicated that scooter-style electric bicycles (SSEBs) were harmful in all cases, especially for young males. Bicycle-style e-bikes (BSEBs) were beneficial when displacing cars but harmful when displacing conventional bicycles. These findings led to three public policy implications. Policy should: a) encourage e-bike types that require some pedaling, b) limit maximum speed and power of e-bikes, and c) only support modal switches to e-bikes from less active forms of transportation.

description: In England a sharp increase in tuition fees and an amplified Governmental drive for a marketised HE system has led to growing pressures for universities to demonstrate value for money and for students to be seen as consumers. There is currently very little empirical research to show how students themselves conceptualise value and their role as a consumer, especially for students who are first in their family to attend HE. This thesis therefore contributes knowledge through the application of a sociological approach to market-making and the theory of performativity to analyse how the student consumer is constructed by regulators and universities, and how market information devices influence first in family student’s perceptions of value for money. Data was collected through a qualitative multi-method research design which included a document analysis of HE regulators and university websites, six focus groups and six follow-up interviews with first in family students in three HE Institutions in the North of England (high, medium and low tariff) between November 2018 and February 2019. Value for money is explored through the themes of choice, quality, costs and benefits which align to the HE regulatory definition (as set by the Office for Students) and is also known empirically as the Net Value Equation. Main findings include multiple examples of how regulators and universities were framing HE as a status market with students having a consumer role, and with a primary value focus on the onward economic significance of a degree. Yet two types of consumer behaviours emerged, one linked to a status/prestige market, and one to standard market depending on participants' prior entry qualifications and aspirations held for the future. Participants' views of themselves as consumers were rejected even though they had clearly performed in this way. Graduate salary information as an indicator of value was also rejected by participants, instead placing an emphasis on a broader imagined future of prosperity and the quality of their student experience. First in family students in this study showed a reduced ability to navigate the complexities of market making tools, and a naivety about important aspects of university life. They are significantly time poor, economically disadvantaged and emotionally challenged by their HE experience and market information tools do not help them to realise the full value of the HE experience.

description: Let k be an algebraically closed field of characteristic zero. Let SH(k) denote the motivic stable homotopy category of T-spectra over k and SH the classical stable homotopy category. Let c:SH -> SH(k) be the functor induced by sending a space to the constant presheaf of spaces on Sm/k. We show that c is fully faithful. In particular, c induces an isomorphism π_n(E)-> π_{n,0}c(E) for all spectra E. Fix an embedding of k into the complex numbers and let Re:SH(k) -> SH be the associated Betti realization. We show that the slice tower for the motivic sphere spectrum has Betti realization which is strongly convergent. This gives a spectral sequence "of motivic origin" converging to the homotopy groups of the classical sphere spectrum; this spectral sequence at E_2 agrees with the E_2 terms in the Adams-Novikov spectral sequence.

description: Diversity of ZEBOV [ Zaire EBOla Virus] proteome was measured by use of Shannon’s entropy [1]. This was done for overlapping nonamers (1–9, 2–10, etc.) of the aligned sequences of each protein. Window size of nine was chosen for immunological applications [2 –3]: it is the typical length of HLA class I T-cell epitopes and the core length of the HLA class II epitopes. T-cell epitopes are short peptides, typically with a core binding length of nine amino acids (nonamers; 9-mers), where one or multiple amino acid changes in the composition can produce combinatorial diversity even when neighboring sites are highly conserved; a single amino-acid change in a nonamer epitope can affect eight other overlapping nonamers [2]. For immunological applications, entropy measure for viral sequences is based on overlapping nonamer peptides (i.e. 1–9, 2–10, 3–11, etc) [2], and the method is described in [3]. These Entropy computations, assiduously carried out by Dr Asif et al, Dean (Perdana, Malaysia) have striking Correlations to "Relative Entropy computations, Kullback-Leiber distance “D” Information content" as explained by Thomas Nordahl Petersen from DTU, Denmark coupled with Prof Dr Hab Jerzy Zbigniew Achimowicz's 1981 Polish Airforce work, Praharshit Sharma's sole authored BDGC: Big Data Genetic Code presented at Nencki Institute of Experimental Biology (14 feb, 2016) and Finally CMBR anisotropic temparature considerations observed via COBE by Francis Mather (2006 Physics NOBEL from NASA, usa) and again Praharshit Sharma's Masters in Bioinformatics thesis on "“STATISTICAL CONSTRAINT ON ANISOU DATA FROM RCSB-PDB WITH SIGNIFICANT CORRELATIONS” whereby 1XY2.pdb (Minimal Decamer/ 10-mer Peptide with ANISOU entries) with NON-hetero-Atom 2-way ANOVA followed by Dimensionality reduction measures as well as Ultimately minimal Oliginucleotide Melting Temperatures of PCR assays as validated by Dr Jayaram group at SCFbio- IIT Delhi all fall into Place!

description: We generalize the noncommutative relations obeyed by the guiding centers in the two-dimensional quantum Hall effect to those obeyed by the projected position operators in three-dimensional (3D) topological band insulators. The noncommutativity in 3D space is tied to the integral over the 3D Brillouin zone of a Chern-Simons invariant in momentum-space. We provide an example of a model on the cubic lattice for which the chiral symmetry guarantees a macroscopic number of zero-energy modes that form a perfectly flat band. This lattice model realizes a chiral 3D noncommutative geometry. Finally, we find conditions on the density-density structure factors that lead to a gapped 3D fractional chiral topological insulator within Feynman's single-mode approximation.

We show that current searches are also sensitive to heavy neutrinos coupling predominantly to the tau lepton, and present limits can significantly constrain the parameter space of general flavour mixing.

Aminoglycoside susceptibility and acquired resistance in Burkholderia vietnamiensis
Creators: name: Jassem, Agatha Natalie
Publisher: name: University of British Columbia
Year: 2013

description: The Burkholderia cepacia complex (BCC) group of Gram-negative bacteria are highly virulent, opportunistic pathogens in cystic fibrosis (CF) patients and other immunocompromised individuals. It is the current dogma that all species of the complex are highly and intrinsically resistant to polycationic antimicrobials, including aminoglycosides, and that this resistance is due to unusual characteristics of the lipopolysaccharide (LPS). Cationic agents enter Gram-negative bacteria through LPS-mediated uptake, relying on anionic lipid A binding sites. Here we observed that environmental and clinical isolates of B. vietnamiensis were more often susceptible to aminoglycosides than those of other BCC species, but were not inhibited by other cationic agents (natural and synthetic cationic antimicrobial peptides, polymyxin B). Furthermore, B. vietnamiensis strains acquired aminoglycoside resistance during chronic CF infection, and in vitro under tobramycin, azithromycin, and hydrogen peroxide pressure. B. vietnamiensis strains also displayed enhanced catalase activity and became less mucoid. Gentamicin and tobramycin time-kill assays revealed drug concentrations up to 8 × the minimum inhibitory concentration were unable to kill a susceptible B. vietnamiensis CF isolate. Aminoglycoside resistant B. vietnamiensis CF isolates accumulated significantly less [³H]gentamicin than susceptible isolates. Aminoglycoside resistance, however, was not correlated with LPS chemotype, and mass spectrometry revealed the presence of lipid A-associated 4-amino-4-deoxy-L-arabinose moieties, residues that neutralize anionic lipid A binding sites, in aminoglycoside-susceptible and -resistant B. vietnamiensis isolates. Furthermore, permeability to the fluorescent hydrophobic probe 1-N-phenylnapthylamine was not enhanced following incubation with gentamicin or tobramycin in any B. vietnamiensis isolates. Aminoglycoside-resistant B. vietnamiensis isolates overexpressed a putative resistance-nodulation-division (RND) efflux system transporter gene, amrB. After serial exposure to tobramycin and azithromycin, but not hydrogen peroxide, amrB expression was induced in an aminoglycoside-susceptible B. vietnamiensis CF isolate. Moreover, inhibition of the putative efflux system enhanced B. vietnamiensis susceptibility to aminoglycosides. These data suggest that active efflux via a RND efflux system, not LPS modification, impairs aminoglycoside accumulation in clinical B. vietnamiensis strains that have acquired aminoglycoside resistance, and in those exposed to tobramycin and azithromycin, but not hydrogen peroxide, in vitro. These new insights may help in the design of improved therapeutic regimens against Burkholderia species.

title: Finances and government of Canterbury eighteenth century to mid nineteenth century
Creators: name: Panton, Frank H.
Publisher: name: University of Kent
Year: 2021

description: From this examination of the progress of local Government in Canterbury, 1700-mid 1800s, in the light of the City's finances, a broad pattern emerges of the oligarchic and self-perpetuating Burghmote clinging to overall control until 1835, adapting its role, with some success, to accommodate changing circumstances. Control of commerce remained the prime concern of the Burghmote, though its gold on the Freeman and Guild system was greatly weakened by the late 1770s. Developments requiring expenditure beyond the Burghmote's limited resources were accommodated and managed through the creation of two new Corporations - Court of Guardians (1727), and Pavement Commissioners (1787) - with powers to levy rates and tolls, which the Burghmote lacked. And, by 1773, the Magistrates began to levy a County Rate defraying the mounting expenses of Canterbury's Commission of the Peace. No great magnate dominated the City, which governed itself with little or no direction from outside. Burghmote members and Magistrates were exclusibely drawn from tradesmen, craftsmen and professionals, living and working in the City. It is suggested that this situation, paralleled in other County Boroughs but not in rural areas, contributed to peaceful government, as evidenced by Canterbury's management, without riots, of food crises of 1795/6 and 1800/1. A degree of urban renaissance, increasing social and leisure activities, was fostered by the ruling elite. Replacement of the Burghmote by a City Council in 1836 introduced a measure of democracy, the abolition of Freemen, and some central government control. A paid police force was established and a Borough rate authorized. However, democracy brought with it links to national politics, and the Council's rates were twice that of the old regime. Despite efforts to increase commerce, the Industrial Revolution passed by, and Canterbury remained a market town, declining in importance relative to other provincial capitals.

description: Cloud computing is a revolutionary computing paradigm which enables flexible, on-demand and low-cost usage of computing resources. However, those advantages, ironically, are the causes of security and privacy problems, which emerge because the data owned by different users are stored in some cloud servers instead of under their own control. To deal with security problems, various schemes based on the Attribute- Based Encryption (ABE) have been proposed recently. However, the privacy problem of cloud computing is yet to be solved. This paper presents an anonymous privilege control scheme AnonyControl to address the user and data privacy problem in a cloud. By using multiple authorities in cloud computing system, our proposed scheme achieves anonymous cloud data access, finegrained privilege control, and more importantly, tolerance to up to (N -2) authority compromise. Our security and performance analysis show that AnonyControl is both secure and efficient for cloud computing environment.

description: We have studied the origin of excess noise in superconducting transition-edge sensors (TES) with several different detector designs. We show that most of the observed noise and complex impedance features can be explained by a thermal model consisting of three bodies. We suggest that one of the thermal blocks and the corresponding thermal fluctuation noise arises due to the high-frequency thermal decoupling of the normal and superconducting phase regions inside the TES film. Our results are also consistent with the prediction that in thin bilayer proximitized superconductors, the jump in heat capacity at the critical temperature is smaller than the universal BCS theory result.

They are applied to quantum metrology to assess the uncertainty in the detection of minute changes of physical quantities. We show that different measures lead to contradictory conclusions, including the possibility of arbitrarily small uncertainty for fixed resources. These intrinsic performances are compared with the averaged error in the corresponding estimation problem after single-shot measurements.

description: Paul Ginsparg recognized the need for central storage of scientific papers and in August 1991 he created a central repository mailbox stored at the Los Alamos National Laboratory (LANL) accessible from any computer. Additional modes of access were soon added: FTP in 1991, Gopher in 1992, and the World Wide Web in 1993. LANL archive began as a physics archive and later expanded to include astronomy, mathematics, computer science, quantitative biology, statistics. In 2001 the archive was moved to Cornell University and named arXiv.org. In a sense the open-access nature of the arXiv pre-prints can be considered as a prerequisite of the Budapest Open Access Initiative in February 2002, the Bethesda Statement on Open Access Publishing in June 2003, and the Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities in October 2003. The “arXiv culture” stimulates the researcher’s ability to share a pre-print of an article before its publication in a journal. The arXiv deposition opens the peer-review process to the entire scientific community with no delay. A remarkable consequence of this peer review is the potential for experts publishing litigation-related work in what are called “predatory journals”. The Open Access opens the road to the Open Science – a term/concept that describes the entire process of conducting and communicating science – sharing FAIR data, methods, codes, open practices to allow critical scrutiny, so that knowledge can be validated and used by the whole community. Open science (“open research”) includes not only open access to content and information but could comprise citizen science projects, scholarly communication networks, open source software and open lab notebooks. How to combine the peer-review process typical for scientific journals and how to protect the intellectual property rights in the realm of openness are Open Questions to be discussed in the talk.

Global Space-Time Symmetries of Quantized Euclidean and Minkowski Superspaces

description: Starting with assumptions both simple and natural from "physical" point of view we present a direct construction of transformations preserving wide class of (anti)commutation relations which describe Euclidean/Minkowski superspace quantizations. These generalized transformations act on deformed superspaces as the ordinary ones do on undeformed spaces but they depend on non(anti)commuting parameters satisfying some consistent (anti)commutation relations. Once the coalgebraic structure compatible with the algebraic one is introduced in the set of transformations we deal with quantum symmetry supergroup. This is the case for intensively studied so called N=1/2 supersymmetry as well as its three parameter extension. The resulting symmetry transformations - supersymmetric extension of theta-Euclidean group can be regarded as global counterpart of appropriately twisted Euclidean superalgebra that has been shown to preserve N=1/2 supersymmetry.

title: Effects of spatially varying slip length on friction drag reduction in wall turbulence

description: A series of direct numerical simulation has been made of turbulent flow over hydrophobic surfaces, which are characterized by streamwise periodic micro-grooves. By assuming that the size of micro-grooves is much smaller than the typical length-scale of near-wall turbulent structures, the dynamical boundary condition is expressed by a mobility tensor, which relates the slip velocity and the surface shear stress. Based on the derived mathematical relationship between the friction drag and different dynamical contributions, it is shown how the turbulence contribution can be extracted and analyzed.

title: The utility of lean project management: conceptions and impacts on project learning
Creators: name: Dowson, J
Publisher: name: Liverpool John Moores University
Year: 2022

description: A particular challenge in project management that has been continually highlighted is the human and social aspects of a complex dynamic project environment. This is characterised by chaos and uncertainty, necessitating more of an insight into the actuality of projects and the development of reflexive practitioners who can learn, adapt and engage through pragmatic application of theory and practices in projects. Although Lean Project Management (LPM) is generally seen as an enabler of progress, the most frequently cited barriers are those connected to Knowledge, Skills and Behaviour – the understanding and ability of individuals to communicate, commit to and undertake change. The research was undertaken through two studies: an Interview Study, which explored the conceptions and lived experiences of 40 project managers, and a single, holistic design Case Study, which explored the relationship between lean project management and project learning (PL) in practice. Multiple sources of evidence contributed to the research, including interviews, non-participant observations, and document and photograph analysis. Thematic analysis was conducted to explore the rich data obtained from both studies. An explanatory framework was developed, which provides an understanding of the relationship between LPM and PL, and its contributory elements. The research suggests the importance and value of socially driven processes and the practice of learning within lean project management that extends knowledge beyond traditional formal and instructive means. Lean Project Management occupies a unique position in that it makes sense of, interacts, responds to and shapes the systems and processes of both learning and practice responsible for project progress. This strengthens its value and utility in being able to address and manage complexities as well as learning and practice within project management.
Secular Dynamical Anti-Friction in Galactic Nuclei

description: We identify a gravitational-dynamical process in near-Keplerian potentials of galactic nuclei that occurs when an intermediate-mass black hole (IMBH) is migrating on an eccentric orbit through the stellar cluster towards the central supermassive black hole (SMBH). We find that, apart from conventional dynamical friction, the IMBH experiences an often much stronger systematic torque due to the secular (i.e., orbit-averaged) interactions with the cluster's stars. The force which results in this torque is applied, counterintuitively, in the same direction as the IMBH's precession and we refer to its action as "secular-dynamical anti-friction" (SDAF). We argue that SDAF, and not the gravitational ejection of stars, is responsible for the IMBH's eccentricity increase seen in the initial stages of previous N-body simulations. Our numerical experiments, supported by qualitative arguments, demonstrate that (1) when the IMBH's precession direction is artificially reversed, the torque changes sign as well, which decreases the orbital eccentricity, (2) the rate of eccentricity growth is sensitive to the IMBH migration rate, with zero systematic eccentricity growth for an IMBH whose orbit is artificially prevented from inward migration, and (3) SDAF is the strongest when the central star cluster is rapidly rotating. This leads to eccentricity growth/decrease for the clusters rotating in the opposite/same direction relative to the IMBH's orbital motion.

description: Much research has been conducted to securely outsource multiple parties' data aggregation to an untrusted aggregator without disclosing each individual's data, or to enable multiple parties to jointly aggregate their data while preserving privacy. However, those works either assume to have a secure channel or suffer from high complexity. Here we consider how an external aggregator or multiple parties learn some algebraic statistics (e.g., summation, product) over participants' data while any individual's input data is kept secret to others (the aggregator and other participants). We assume channels in our construction are insecure. That is, all channels are subject to eavesdropping attacks, and all the communications throughout the aggregation are open to others. We successfully guarantee data confidentiality under this weak assumption while limiting both the communication and computation complexity to at most linear.
