Surface freight transportation in Mexico post NAFTA

One of the significant expressed objectives of NAFTA was the improvement of cross-border transportation to enable a more efficient and cost effective flow of goods among Mexico, Canada and the United States. This article examines the changes that have taken place in surface freight transportation between Mexico and the U.S. since NAFTA was signed in 1993

The Jones Act: it is time for reform

The Jones Act was passed in 1920 as an amendment to the Merchant Marine Act. Its initial purpose was to protect a rail monopoly operating between the state of Washington and the territory of Alaska. It restricted transportation between U.S. ports to U.S. built, owned, registered and crewed vessels. Over the past 77 years it has become very controversial. This paper examines its costs and benefits and concludes that the Jones Act is indeed in need of major reform

Maritime unions and the U.S. merchant marine

U.S. maritime unions have played a vital historical role in both the defense and the economic development of the United States. The economic and the political forces that helped shape and promote the growth of U.S. seafaring labor unions changed dramatically in the 1990s. Maritime union membership in the United States has fallen by more than 80 per cent since 1950. Inflexible union work rules and high union wage scales have contributed to this decline. Recent regulatory and industry changes require a new union approach if U. S. maritime unions are to survive the next decade

The use of EDI and internet technologies in the U.S. motor carrier industry

Computer to computer data exchange by companies in a supply chain have been wellrecognized as an effective means of reducing cost and decreasing paperwork errors. In many cases, manufacturers, wholesalers, and retailers have become electronically linked to better manage inventory, ordering, and billing information. However, supply chains, by definition, also include common carriers that move goods between supply chain partners but may not have a long-term relationship with either the shipper or his customers. This could be the missing or weak link in an otherwise effective supply chain. The purpose of this paper is to examine the state-of-the-art of EDI in the motor carrier industry to identify possible trends

The Neo-Platonic Christianity of C. S. Lewis

I shall attempt to show how Lewis’s fusion of Platonism with Christianity gives rise to his belief, metaphysically speaking, that the physical universe is not all there is but, rather, “transposes” (as he terms it) a greater non-physical or spiritual reality and is, as such, part of a divinely-ordained, orderly, and purposeful scheme of things. I shall also argue that for Lewis, epistemologically speaking, knowledge of this grand design and the place of humans therein is conveyed not through the human senses, at least as these are conventionally conceived, but, rather, through our higher reason, which is capable of objective insight into the true nature of reality. I shall conclude by contending that Lewis believes, from an ethical, social, and political point of view, that well-doing and well-being at both the individual and collective levels are attained through a combination of wisdom as to the true nature of things, the courage to act in accordance with this knowledge, the moderation of self-interest in the form of the surrender of one’s individual will to God’s, and, last but not least, justice in the form of a hierarchy of functions both within the soul and without

Paradise Retained: C. S. Lewis on the Nature of Knowledge, Reality, and Morality in Perelandra

The world-view which informs Perelandra (1943) in particular and the so-called “space trilogy” more generally, of which it is the second volume, is deeply infused with that blend of Christianity and Platonism that is the hallmark of the thought of C. S. Lewis and which I explore at some length in the companion essay to this piece in this volume, “The Neoplatonic Christianity of C. S. Lewis.” Perelandra is, I would argue, a literary rendition of some of the most important philosophical arguments in defense of Christianity mounted by Lewis in Mere Christianity and elsewhere

Next generation software environments : principles, problems, and research directions

The past decade has seen a burgeoning of research and development in software environments. Conferences have been devoted to the topic of practical environments, journal papers produced, and commercial systems sold. Given all the activity, one might expect a great deal of consensus on issues, approaches, and techniques. This is not the case, however. Indeed, the term "environment" is still used in a variety of conflicting ways. Nevertheless substantial progress has been made and we are at least nearing consensus on many critical issues.The purpose of this paper is to characterize environments, describe several important principles that have emerged in the last decade or so, note current open problems, and describe some approaches to these problems, with particular emphasis on the activities of one large-scale research program, the Arcadia project. Consideration is also given to two related topics: empirical evaluation and technology transition. That is, how can environments and their constituents be evaluated, and how can new developments be moved effectively into the production sector

Intertidal invertebrate harvesting: a meta-analysis of impacts and recovery in an important waterbird prey resource

Harvesting of marine invertebrates in intertidal areas often comes into conflict with conservation objectives for waterbird populations of the orders Anseriformes and Charadriiformes. We present a meta-analysis of the relationships between benthic invertebrate communities and various sources of intertidal harvesting disturbance to investigate impacts and recovery in bird prey resources. The effect size (Hedges’ d) of harvesting on benthic species abundance, diversity and biomass was calculated for 38 studies in various locations globally, derived from 16 publications captured through a systematic review process that met the meta-analysis inclusion criteria. A negative response to harvesting disturbance was found for all taxa, including both target and non-target species, that represent important types of waterbird prey. Impacts appear most severe from hand-gathering, which significantly reduces the abundance of target polychaete species, a key prey group for many bird species. Across all gear types, non-target species demonstrate a larger reduction in abundance compared to target species. Recovery trends vary, with differences observed between taxonomic groups and gear/habitat combinations. Abundance of bivalve molluscs, a potentially highly profitable bird prey item, is suppressed for >60 d by mechanical dredging in intertidal mud, while annelid and crustacean abundances demonstrate near recovery over the same period. Data suggest that recovery following harvesting in sandier habitats may in some cases take as long as or longer than in muddy sediments. We recommend management measures to minimise disturbance to benthic prey resources and support conservation objectives for waterbird populations to meet international legal requirements

Parents' and guardians' views on the acceptability of a future COVID-19 vaccine: A multi-methods study in England.

BACKGROUND: The availability of a COVID-19 vaccine has been heralded as key to controlling the COVID-19 pandemic. COVID-19 vaccination programme success will rely on public willingness to be vaccinated. METHODS: We used a multi-methods approach - involving an online cross-sectional survey and semi-structured interviews - to investigate parents' and guardians' views on the acceptability of a future COVID-19 vaccine. 1252 parents and guardians (aged 16 + years) who reported living in England with a child aged 18 months or under completed the survey. Nineteen survey participants were interviewed. FINDINGS: Most survey participants reported they would likely accept a COVID-19 vaccine for themselves (Definitely 55.8%; Unsure but leaning towards yes 34.3%) and their child/children (Definitely 48.2%; Unsure but leaning towards yes 40.9%). Less than 4% of survey participants reported that they would definitely not accept a COVID-19 vaccine. Survey participants were more likely to accept a COVID-19 vaccine for themselves than their child/children. Participants that self-reported as Black, Asian, Chinese, Mixed or Other ethnicity were almost 3 times more likely to reject a COVID-19 vaccine for themselves and their children than White British, White Irish and White Other participants. Survey participants from lower-income households were also more likely to reject a COVID-19 vaccine. In open-text survey responses and interviews, self-protection from COVID-19 was reported as the main reason for vaccine acceptance. Common concerns identified in open-text responses and interviews were around COVID-19 vaccine safety and effectiveness, mostly prompted by the newness and rapid development of the vaccine. CONCLUSION: Information on how COVID-19 vaccines are developed and tested, including their safety and efficacy, must be communicated clearly to the public. To prevent inequalities in uptake, it is crucial to understand and address factors that may affect COVID-19 vaccine acceptability in ethnic minority and lower-income groups who are disproportionately affected by COVID-19
