A Holistic Approach to Curriculum Design â an example from dietetic practice education
Practice Education is an integral component of all student dietitiansâ academic programme. This paper outlines how a holistic, situational model of curriculum design was used to redesign a two-week clinical placement module to facilitate application of theory and development of core professional attributes based on pre-existing learning outcomes. This module is currently a core professional development module for all Human Nutrition and Dietetics BSc and PGDip student
The path of fiduciary law
Contemporary accounts of corporate legal evolution view lawmakers as highly responsive to the economic interests of both pressure groups and markets. Through this lens law is understood to be the product of pressures exerted by managers, investors, institutional shareholders and the Federal Government, and the incentives of state lawmakers to accommodate the interests of these pressure groups. This lens dominates our current understanding of corporate legal evolution in the United States and is becoming highly influential in comparative accounts of corporate legal variation. This article sounds a note of objection. The article argues that the disciplinary pendulum has swung too far toward external accounts of legal evolution and too far away from internal accounts of legal change which view the path of law, at least in part, as the product of the internally generated constraints of the legal system â the relative autonomy of the law. To make this argument, the article considers the internal constraint of the conception of the corporation in 19th century US and UK corporate law and the evolution of self-dealing law in these two jurisdictions. It shows how two jurisdictions that started from the same legal proposition about self-dealing diverged rapidly as a result of the interaction of this proposition with profoundly different conceptions of the corporation. Contrary to the dominant account of the evolution of self-dealing law in the United States, the contemporary self-dealing rule is not the legally unexplained product of external market pressures but the logical and consistent product of the path of fiduciary law trodden through the corporate conception. The article shows that for contemporary corporate law a significant dose of inevitability was administered at the inception of general incorporation
The illusion of importance: reconsidering the UK's takeover defence prohibition
This article considers the significance of the UK Takeover Code's non-frustration prohibition. It asks to what extent the prohibition actually prevents post-bid, director-controlled defences that would not have been, in any event, either formally prohibited by UK company law without share-holder approval or practically ineffective as a result of the basic UK company law rule set. It finds that there would be minimal scope for director-deployed defences in the absence of the non-frustration prohibition, and that, in the context of UK company law, such defences have limited scope to be deployed for entrenchment purposes. Furthermore, this minimal scope for board defensive action would, in order to be compliant with a director's duties, require a pre-bid, shareholder-approved alteration to the UK's default constitutional balance of power between the board and the shareholder body to allow corporate powers to be used for defensive effect. In light of this conclusion the article looks for a rationale to justify denying shareholders the right to make this limited and potentially beneficial defensive election. It concludes that no persuasive rationale is available and that the prohibition is unnecessary and without justification
Status and Potential of Fisheries and Aquaculture in Asia and the Pacific 2006
This publication highlights the interconnectivity and linkages between coastal ecosystems (mangroves, coral reefs, seagrasses, estuaries, and lagoons) across environ-mental, economic, social, and management contexts. It presents innovative approaches to better understand, protect and value ecosystems services across linked habitats, informing the trade-off of different land-use management decisions and the effects on healthy systems from drawing on ecosystem services from linked habitats. This report presents further evidence of the need to develop appropriate economic and governance frameworks that best protect the essential services from natural ecosystems that human populations will need for the future
Palaeoecology of corals and stromatoporoids in a late Silurian biostrome in Estonia
A middle Ludlow biostrome at Katri, western Estonia, the richest accumulation of corals and stromatoporoids in Estonia, is partly exposed in a coastal section ca. 1 m high, 150 m long. The fully marine biostrome consists of 5 layers of skeletal carbonate, grouped into Facies 1 (grainstone-packstone, layers 1, 3 & 5) and Facies 2 (wackestone, interbedded layers 2 & 4). Pressure solution degraded original sedimentary relationships and morphologies of stromatoporoids, tabulates and rugosans which constructed the biostrome, but the two facies have major faunal differences. Facies 1 is rich in stromatoporoids âStromatoporaâ bekkeri and Plectostroma scaniense (low to high domical up to ca. 30 cm basal length); and tabulate Favosites forbesi (bulbous to high domical up to ca. 25 cm wide). In Facies 2, all three taxa are less common and much smaller. Instead, the most abundant stromatoporoid is laminar Syringostromella borealis up to 30 cm basal length; the most abundant coral is erect branching Laceripora cribrosa, as scattered fragments up to 24 cm long. Neither occurs in Facies 1. Six other stromatoporoid taxa, 5 other tabulate and 5 rugosan taxa occur uncommonly in the biostrome, mostly in both facies. The Katri biostrome is slightly younger than, but similar facies to, biostromes in the middle Ludlow Hemse Group on Gotland ca. 250 km WSW, with well-known stromatoporoid faunas. Corals are abundant in Hemse biostromes, but taxonomy awaits full study. Several key stromatoporoids occur in both the Hemse biostromes and Katri, but two abundant taxa in Hemse biostromes are absent in Katri and two tabulate corals abundant in Katri are missing in Hemse biostromes. Thus there was wide distribution of such biostromes in the central Baltic large shallow marine carbonate platform, but with previously unreported variable assemblages presumed due to facies features not recognised in the sediments
Non-equilibrium Green's function theory for non-adiabatic effects in quantum transport: inclusion of electron-electron interactions
Non-equilibrium Green's function theory for non-adiabatic effects in quantum
transport [Kershaw and Kosov, J.Chem. Phys. 2017, 147, 224109 and J. Chem.
Phys. 2018, 149, 044121] is extended to the case of interacting electrons. We
consider a general problem of quantum transport of interacting electrons
through a central region with dynamically changing geometry. The approach is
based on the separation of time scales in the non-equilibrium Green's functions
and the use of Wigner transformation to solve the Kadanoff-Baym equations. The
Green's functions and correlation self-energy are non-adiabatically expanded up
to the second order central time derivatives. We produced expressions for
Green's functions with non-adiabatic corrections and modified formula for
electric current; both depend not only on instantaneous molecular junction
geometry but also on nuclear velocities and accelerations. The theory is
illustrated by the study of electron transport through a model single-resonant
level molecular junction with local electron-electron repulsion and a
dynamically changing geometry
Nonadiabatic corrections to electric current in molecular junction due to nuclear motion at the molecule-electrode interfaces
We present quantum electron transport theory that incorporates dynamical
effects of motion of atoms on electrode-molecule interfaces in the calculations
of the electric current. The theory is based on non-equilibrium Green's
functions. We separate time scales in the Green's functions on fast relative
time and slow central time. The derivative with respect to the central time
serves as a small parameter in the theory. We solve the real-time Kadanoff-Baym
equations for molecular Green's functions using Wigner representation and keep
terms up to the second order with respect to the central time derivatives.
Molecular Green's functions and consequently the electric current are expressed
as functions of molecular junction coordinates as well as velocities and
accelerations of molecule-electrode interface nuclei. We apply the theory to
model a molecular system and study the effects of non-adiabatic nuclear motion
on molecular junction conductivity
Palaeobiology, ecology, and distribution of stromatoporoid faunas in biostromes of the mid-Ludlow of Gotland
Six well exposed midâLudlow stromatoporoidâdominated reef biostromes in four localities from the Hemse Group in southeastern Gotland, Sweden comprise a stromatoporoid assemblage dominated by four species; Clathrodictyon mohicanum, âStromatoporaâ bekkeri, Plectostroma scaniense, and Lophiostroma schmidtii. All biostromes investigated in this area (of approximately 30 km2) are interpreted to belong to a single faunal assemblage forming a dense accumulation of fossils that is probably the best exposed stromatoporoidârich deposit of the Silurian. The results from this comprehensive study strengthen earlier interpretations of a combination of genetic and environmental control on growthâforms of the stromatoporoids. Growth styles are similar for stromatoporoids in all six biostromes. Differences in biostrome fabric are due to variations in the degree of disturbance by storms. The uniformity of facies and the widespread lowâdiversity fauna support the view that palaeoenvironmental conditions were similar across the area where these biostromes crop out, and promoted the extraordinary growth of stromatoporoids in this shallow shelf area
An investigation into psychological distancing and its impact on executive functioning after stroke
Section A
Section A is a systematic literature review investigating the broad phenomenon of psychological distancing and its effects on cool executive functioning performance. The extant literature is searched, relevant studies are then reviewed and critiqued to provide an overview of the current research in this novel field. The research question asks, âWhat impact does psychological distancing have on cool executive functioning performance?â. Gaps in the literature and recommendations for research and clinical practice are discussed.
Section B
Section B is an empirical paper extending the application of psychological distancing theory to a clinical population, namely stroke survivors. The ability to psychologically distance oneself from oneâs usual âhere and nowâ perspective may be particularly applicable to those who have experienced stroke. A mixed-methods design was employed to investigate whether creating psychological distance through role-taking impacted stroke survivorsâ âinhibitionâ, âcognitive flexibilityâ and âworking memoryâ performance. Participants also provided qualitative feedback on their experience and thematic analysis was used to build an understanding of how this novel strategy may be applicable to life after stroke
Population trends and priority conservation sites for Mexican Duck Anas diazi
Little is known about Mexican Duck Anas diazi biology and populations. We analyse long-term (1960â2000) trends of Mexican Duck numbers in Mexico and employ contemporary count data (1991â2000) from the U.S. Fish and Wildlife Service midwinter surveys to identify key sites for conservation using a complementarity approach. The overall Mexican Duck population showed a significant long-term increase of 2.5% per year, with large fluctuations throughout the study period. The Northern highlands population increased at an annual rate of 7.7%, while the Central highlands population showed no significant long-term trend. During the last decade, counts in both the Northern and Central highlands exhibited no significant change. At the site level, significant long-term increases occurred in four localities in the Northern highlands (Laguna BabĂcora +13.9% annually, Laguna Bustillos +25.9%, Laguna Mexicanos +20.4% and Laguna Santiaguillo +16.9%) and in three localities in the Central highlands (Languillo +15.3% annually, Presa SolĂs +8.9%, Zacapu +13.4%). Two sites in the Central highlands showed significant declines, in the long term (Lago de Chapala, -5.2% per year) and during the last decade (Lerma, -11.8% per year).
The Northern highlands held 16% and the Central highlands 84% of the Mexican Duck population in the period 1960â2000; during the last decade, these figures were 31% and 69%, respectively. A set of priority sites for conservation of the Mexican Duck was identified, consisting of 15 sites holding more than 70% of the midwinter Mexican Duck counts in Mexico. Ten sites from the priority set also qualify for designation as wetlands of international importance under the Ramsar Convention on Wetlands, by holding [greater-than-or-equal] 1% of the estimated population. Four of the priority sites are in the Northern highlands and 11 in the Central highlands, of which eight are distributed along the Rio Lerma drainage. The most urgent actions that need to be undertaken are to estimate the current minimum population size in Mexico; to establish a programme for monitoring populations in the priority sites, especially those located within the highly degraded Rio Lerma drainage; and to determine the most feasible management actions for the species, concentrating efforts around the priority sites
