The Positive Feedback Advantages of Combining Buying and Investing  [PDF]
Vic Norris, Laura Norris, Wing-Keung Wong
Theoretical Economics Letters (TEL) , 2015, DOI: 10.4236/tel.2015.55077
Abstract: A substantial proportion of the world’s population is dissatisfied with the way the global market-based economy operates. In particular, the desire of consumers to pay as little as possible for a product and the desire of producers and investors to make as much profit as possible, lead to actions that drive down wages, undermine social welfare and damage the environment. To counteract this, we propose that the millions of consumers who wish to change the market adopt a combined buying and investing strategy that we term buyvesting in which “ethical” would become the new “profitable”. We use a learning program to illustrate the buyvesting proposal, which we discuss with respect to the concepts of competitive coherence and shared reality theory.
Efficacy of long-lasting insecticidal nets in use in Macha, Zambia, against the local Anopheles arabiensis population
Laura C Norris, Douglas E Norris
Malaria Journal , 2011, DOI: 10.1186/1475-2875-10-254
Abstract: F1 offspring of field-collected adult An. arabiensis were tested for insecticide resistance, using CDC bottle bioassays and deltamethrin ITN susceptibility assays. The mosquitoes were characterized for the knock-down resistance (kdr) allele by PCR. LLINs that had been in use for two years in nearby villages were collected and tested for residual deltamethrin concentration and net quality, and were used in bioassays against susceptible colonized Anopheles gambiae s.s. Keele. Additionally, a survey on ITN use and care was conducted among LLIN owners.In the F1 An. arabiensis field population, low levels of resistance to DDT and deltamethrin-treated net material were detected by bioassay, although the knock-down resistance (kdr) allele not present in the population. ITN evaluations revealed high variability in residual deltamethrin concentration, quality of the nets, and mosquito mortality in bioassays. Mortality against An. gambiae s.s. in bioassays was correlated with residual deltamethrin concentration, which was dependent upon the number of washes each net had received.Proper LLIN care was a strong determinant of LLIN efficacy, indicating that education on the importance of LLIN use and care is key when distributing nets. As there is little insecticide resistance in the local vector population, degradation of LLINs most likely allowed for continued human feeding by An. arabiensis. Continued monitoring and assessment of both the vector population and the efficacy of LLINs in use is necessary in order to appropriately modify vector control operations and prevent the development of pyrethroid resistance.Malaria is a severe public health problem, causing an estimated 225 million disease cases and 781,000 deaths per year [1]. Most victims are children under five years old living in sub-Saharan Africa [1]. Malaria is transmitted by Anopheles mosquitoes, and because there is currently no vaccine available, vector control is one of the most important means of malaria preven
Abundances of C, N, Sr and Ba on the red giant branch of omega Centauri
Laura M. Stanford,Gary S. Da Costa,John E. Norris
Physics , 2010, DOI: 10.1088/0004-637X/714/2/1001
Abstract: Abundances relative to iron for carbon, nitrogen, strontium and barium are presented for 33 stars on the red giant branch of the globular cluster omega Centauri. They are based on intermediate-resolution spectroscopic data covering the blue spectral region analyzed using spectrum synthesis techniques. The data reveal the existence of a broad range in the abundances of these elements, and a comparison with similar data for main sequence stars enables insight into the evolutionary history of the cluster. The majority of the red giant branch stars were found to be depleted in carbon, i.e. [C/Fe]<0, while [N/Fe] for the same stars shows a range of ~1 dex, from [N/Fe]~0.7 to 1.7 dex. The strontium-to-iron abundance ratios varied from solar to mildly enhanced (0.0<=[Sr/Fe]<=0.8), with [Ba/Fe] generally equal to or greater than [Sr/Fe]. The carbon and nitrogen abundance ratios for the one known CH star in the sample, ROA 279, are [C/Fe]=0.6 and [N/Fe]=0.5 dex. Evidence for evolutionary mixing on the red giant branch is found from the fact that the relative carbon abundances on the main sequence are generally higher than those on the red giant branch. However, comparison of the red giant branch and main sequence samples shows that the upper level of nitrogen enhancement is similar in both sets at [N/Fe]~2.0dex. This is most likely the result of primordial rather than evolutionary mixing processes. One red giant branch star, ROA 276, was found to have Sr and Ba abundance ratios. High resolution spectra of ROA 276 were obtained with the Magellan Telescope/MIKE spectrograph combination to confirm this result, revealing that ROA 276 is indeed an unusual star. For this star calculations of the depletion effect strongly suggest that the observed Sr enhancement in ROA 276 is of primordial origin, rather than originating from a surface accretion event.
Spectroscopy of Main Sequence Stars in Globular Clusters
Russell Cannon,Gary Da Costa,John Norris,Laura Stanford,Barry Croke
Physics , 2002,
Abstract: Although globular clusters are generally chemically homogeneous, substantial abundance variations are sometimes seen even among unevolved main sequence stars, especially for the CNO group of elements. Multi-object intermediate-dispersion spectroscopic systems are now being used to determine the patterns of abundance variations for large samples of stars, while high dispersion spectrographs on 8m-class telescopes are providing good spectra of individual faint stars. In some circumstances the spectra of many similar stars can be combined to yield extremely high S/N spectra. The sample of clusters which has been studied remains small, but it seems that many of the more metal-rich clusters must have experienced some sort of self-enrichment, either in a proto-cluster stage, or through successive episodes of star formation or some other processes early in their lives. The metal-poor clusters provide equally clear evidence for internal mixing and dredge-up of processed material within evolving red giant stars.
Managing Conflict in a Time Critical Environment—A Neglected Non-Technical Skill Submission for Special Edition—Team Management  [PDF]
Elizabeth M. Norris
Open Journal of Applied Sciences (OJAppS) , 2016, DOI: 10.4236/ojapps.2016.62013
Abstract: The aim of this study was to the explore the nature of conflict and increase the understanding of the role of conflict as a non-technical skill, drawing on literature from organizational behaviour, leadership, patient safety and medical simulation. The review highlights the different conflict types in time critical settings, both emotional and constructive. It proposes that it may be possible to use this knowledge to enable team leaders and team members to be aware of “emotional” or “dysfunctional” conflict, and appreciate when it is about to escalate and consider strategies that could be useful in such a setting to defuse it. “Emotional conflict” is often exacerbated by stress and/or previous learned feelings of failure or helplessness. If individuals learn to recognise conflict does not have to be destructive and learn techniques such as reappraising a situation, active listening and good respectful communication with team members, the emotional climate in teams could be improved and useful discussion regarding patient care would ensue. Finally the study hopes to show how teams could make use of “constructive” conflict to improve team function, team member confidence and a flattening of hierarchies within the team.
Are Otters an Effective Flagship for the Conservation of Riparian Corridors in an Amazon Deforestation Frontier?
Darren Norris,Darren Norris
IUCN Otter Specialist Group Bulletin , 2009,
Abstract: Using flagship species to generate support for conservation activities has been successfully applied in some regions. We investigated whether using otters as a flagship for the conservation of riparian corridors in an Amazonian deforestation frontier would be likely to result in similar success. Between December 2007 and May 2009, we conducted 64 interviews with local landowners in the region of Alta Floresta (MT, Brazil). These interviews revealed a neutral attitude towards otters, which indicates that direct persecution (e.g. retaliation against otter predation on fish) is unlikely in the region. However, it also suggested that using otters as a flagship to generate local support for regional conservation activities will not be effective. There was a sharp contrast with the replies to questions regarding riparian corridors, where interviews did reveal strong positive attitudes. These results suggested that to conserve Giant Otters in the Amazon “Arc of deforestation”, efforts should focus on the support of maintenance of riparian corridors connecting forest fragments by local people.
A tese da "nova clivagem" e a base social do apoio à direita radical
Norris, Pippa;
Opini?o Pública , 2005, DOI: 10.1590/S0104-62762005000100001
Abstract: the rise of the radical right is open to multiple interpretations. the question addressed in this paper is whether many of these parties have fostered an enduring social base among core voters and, if so, which social sectors are most likely to support them. the first part discusses the alternative theoretical frameworks provided by the classic accounts of the 1950s and 1960s, the "new social cleavage" thesis common during the last decade, and the theory of partisan dealignment. then, it compares evidence to analyze rival hypotheses about the social basis of the radical right vote across fifteen nations, using data drawn from the european social survey, 2002, and the comparative study of electoral systems, 1996-2001. the second part focuses upon the role of socioeconomic indicators, while the third part considers the enduring gender gap and patterns of generational support. the conclusion considers the implications of these results for understand ing the basis of radical right popularity, and for the stability and longevity of these parties.

Can Realism Be Naturalized?
Christopher Norris
Principia : an International Journal of Epistemology , 2000,
Abstract: Hilary Putnam has famously undergone some radical changes of mind with regard to the issue of scientific realism and its wider epistemological bearings. In this paper I defend the arguments put forward by early Putnam in his essays on the causal theory of reference as applied to natural-kind terms, despite his own later view that those arguments amounted to a form of 'metaphysical' realism which could not be sustained against various lines of sceptical attack. I discuss some of the reasons for Putnam's retreat, first to the theory of 'internal (or framework-relative) realism proposed in his middle-period writings, and then to a commonsense pragmatist stance which claims to resituate this whole discussion on ground that has not been trodden into ruts by the contending philosophical schools. In particular I examine his protracted engagement with various forms of anti-realist doctrine (Michael Dummet’s most prominent among them), with Wittgenstein's thinking about language-games or meaning-as-use, and with a range of skeptical - relativist positions adopted in the wake of Quine’s influential attack on the two last 'dogmas' of logical empiricism. My paper seeks to show that Putnam has been over-impressed by some of the arguments — from these and other sources — which he takes to constitute a knock-down case against the kind of externalist and causal-realist approach developed in his early essays. It concludes by re-stating that position in summary form and relating it to other, more recent defences of causal realism in epistemology and philosophy of science.
Treading Water in Neurath's Ship: Quine, Davidson, Rorty
Christopher Norris
Principia : an International Journal of Epistemology , 1998,
Abstract: This article examines what I take to be some of the wrong turns and false dilemmas that analytic philosophy has run into since Quine's well-known attack on the two 'last dogmas' of old-style Logical Empiricism. In particular it traces the consequences of Quine's argument for a thoroughly naturalized epistemology, one that would view philosophy of science as 'all the philosophy we need', and that defines 'philosophy of science' in narrowly physicalist terms. I contend that this amounts to a third residual dogma of empiricism and that its effect has been chiefly to restrict the range of post-Quinean debate by setting an agenda which preemptively excludes all interest in the wider (i.e., critical and normative) dimensions of philosophic enquiry. Its influence can be seen in various responses to Quine, among them those of Donald Davidson and Richard Rorty, both of whom adopt a similar, reductively physicalist approach to issues of meaning, knowledge and truth. Where Davidson takes issue with other Quinean doctrines such as framework-relativism and radical meaning-variance, Rorty pushes those doctrines right through to a wholesale relativist (or 'textualist') position according to which interpretation is completely unconstrained by the mere fact of a causal 'correspondence' between beliefs and reality. What they both share — and what thus lays Davidson open to a revisionist reading in Rorty's favoured style — is this Quine-derived notion that beliefs can be explained in terms of a reflex stimulus-response psychology that finds no room for normative issues of epistemological warrant or justification. For it will then seem plausible for Rorty to claim that any 'beliefs' acquired by such a rudimentary mechanism are compatible with pretty much any higher-level theory or description that one cares to place upon them. My article goes on to criticize Rorty's most extreme statement of the case — in his essay 'Texts and Lumps' — and (more constructively) to suggest some ways forward from this post-empiricist predicament.
