Marketing and the Common Good: Implications of \u3cem\u3eCaritas in Veritate\u3c/em\u3e
This paper extends the authors’ previous work on applying Catholic Social Teachings to issues in marketing to the specific question of the common good. Approaches to studying the social impact of marketing and the challenge of adequately defining the common good are discussed. Attention is next given to key vectors of Catholic Social Teaching and their application to ethical issues in marketing. The focus of the analysis is on specific sections in Caritas in Veritate, Pope Benedict XVI’s recent encyclical devoted to providing principles for dealing with the ongoing global economic crisis. A discussion of how these principles might be applied to business and public policy follows. We close with an evaluation of this application
Siphonaptera Records and Host Associations From the Central and Eastern Upper Peninsula of Michigan
Fleas were collected from birds and mammals over a five year period in four upper peninsula counties. Identified specimens were compared to published records of distribution for the parasite species and its host species, and only those records which are new county distributions for host or parasite are listed. Four new host records for Michigan, four new flea distribution records for the upper peninsula, and 26 new county records are listed
Ethical Marketing: A Look on the Bright Side
This article offers an alternative to conventional approaches to ethical analysis in business and marketing. We submit that studying companies with exemplary records of ethical conduct and social responsibility offers useful and compelling guidance to marketing students and managers. It provides another needed perspective beyond simply examining examples of misconduct or offering normative advice that may not reflect the specifics of corporate situations. Based on examples presented in a recent text by the authors and Better Business Bureau Torch Awardees, we present information on thirteen companies of varying size and from several different industries. That information includes ethics policies, management practices, environmental practices, and company reputation. From these examples, we draw lessons that should offer ethical guidance to marketing managers
Strongly coupled large-angle stimulated Raman scattering of short laser pulses in plasma-filled capillaries
Strongly coupled large-angle stimulated Raman scattering (LA SRS) of a short
intense laser pulse proceeds in a plane plasma-filled capillary differently
than in a plasma with open boundaries. Oblique mirror reflections off capillary
walls partly suppress the lateral convection of scattered radiation and
increase the growth rate of the instability: the convective gain of the LA SRS
falls with an angle much slower than in an unbounded plasma and even for the
near-forward SRS can be close to that of the direct backscatter. The long-term
evolution of LA SRS in the interior of the capillary is dominated by
quasi-one-dimensional leaky modes, whose damping is related to the transmission
of electromagnetic waves through capillary walls.Comment: 11 pages, 6 figures; to be submitted to Physics of Plasma
The signal-to-noise analysis of the Little-Hopfield model revisited
Using the generating functional analysis an exact recursion relation is
derived for the time evolution of the effective local field of the fully
connected Little-Hopfield model. It is shown that, by leaving out the feedback
correlations arising from earlier times in this effective dynamics, one
precisely finds the recursion relations usually employed in the signal-to-noise
approach. The consequences of this approximation as well as the physics behind
it are discussed. In particular, it is pointed out why it is hard to notice the
effects, especially for model parameters corresponding to retrieval. Numerical
simulations confirm these findings. The signal-to-noise analysis is then
extended to include all correlations, making it a full theory for dynamics at
the level of the generating functional analysis. The results are applied to the
frequently employed extremely diluted (a)symmetric architectures and to
sequence processing networks.Comment: 26 pages, 3 figure
A Comparative Study of the Magnitude, Frequency and Distribution of Intense Rainfall in the United Kingdom
During the 1960s, a study was made of the magnitude, frequency and distribution of intense rainfall over the UK, employing data from more than 120 daily-read rain gauges covering the period 1911 to 1960. Using the same methodology, that study was recently updated utilizing data for the period 1961 to 2006 for the same gauges, or from those nearby. This paper describes the techniques applied to ensure consistency of data and statistical modelling. It presents a comparison of patterns of extreme rainfalls for the two periods and discusses the changes that have taken place. Most noticeably, increases up to 20% have occurred in the north west of the country and in parts of East Anglia. There have also been changes in other areas, including decreases of the same magnitude over central England. The implications of these changes are considered
Perspectives on subnational carbon and climate footprints: A case study of Southampton, UK
Sub-national governments are increasingly interested in local-level climate change management. Carbon- (CO2 and CH4) and climate-footprints—(Kyoto Basket GHGs) (effectively single impact category LCA metrics, for global warming potential) provide an opportunity to develop models to facilitate effective mitigation. Three approaches are available for the footprinting of sub-national communities. Territorial-based approaches, which focus on production emissions within the geo-political boundaries, are useful for highlighting local emission sources but do not reflect the transboundary nature of sub-national community infrastructures. Transboundary approaches, which extend territorial footprints through the inclusion of key cross boundary flows of materials and energy, are more representative of community structures and processes but there are concerns regarding comparability between studies. The third option, consumption-based, considers global GHG emissions that result from final consumption (households, governments, and investment). Using a case study of Southampton, UK, this chapter develops the data and methods required for a sub-national territorial, transboundary, and consumption-based carbon and climate footprints. The results and implication of each footprinting perspective are discussed in the context of emerging international standards. The study clearly shows that the carbon footprint (CO2 and CH4 only) offers a low-cost, low-data, universal metric of anthropogenic GHG emission and subsequent management
