A New Method for the Determination of Texture Functions From Incomplete Pole Figures—Comparison With Older Methods
Authors: Van Houtte P. 
Published: April 2008

Three series expansion methods for texture analysis from incomplete pole figures have
been compared. Method I is the presently most used method, method II is a variant
of it and method III is entirely new. Computer programs have been written for the three
methods.Incomplete pole figures have then been prepared from known textures of f.c.c. metals.
In some cases, artificial experimental errors have been simulated. These pole figures were
analyzed by the three computer programs, after which the resulting texture functions
were compared to the original texture functions.No significant differences were found for weak textures. On the other hand, the results
of method I are much poorer than those of the two other methods for sharp textures,
because it underestimates the normalisation factors.The best results were obtained by method III.

Authors: Philippe M. J. , Esling C. , Hocheid B. 
Published: April 2008

This paper presents an extensive study of the conditions of appearance of mechanical twinning and its role in the texture development during uniaxial tension, biaxial expansion and rolling of Ti and Zr alloys.With the help of literature, the analyses are extended to alloys of Mg, Zn and Be.Finally, the influence of twinning on the shape of the forming limit diagrams and on formability is discussed for hexagonal metals.
Calculation of the Yield Locus of Textured Polycrystals Using the Taylor and the Relaxed Taylor Theory
Authors: Houtte P. Van 
Published: April 2008

Several authors have proposed methods which use the Taylor–Bishop–Hill theory in order to calculate the yield surface of textured samples of which the O.D.F. is known.The purpose of this paper is to show how these methods can be generalized while keeping the computational effort within reasonable limits. It must be emphasized that the new method produces “true” plane sections of the yield locus instead of so‐called “principle strain yield loci.”A theorem that permits the exploitation of the sample symmetry is demonstrated. After a general description of the method, it is explained how the theorem can be used in order to restrict the number of deformation modes that must be considered.The next section discusses how a data bank of Taylor factors can be constructed. The full‐constraint Taylor theory as well as the relaxed Taylor theory are considered.In the next section, it is explained how the plane sections through the multidimensional yield locus are generated. A few applications are finally discussed, including a study of the elongation of a torsion sample of which the O.D.F. has been measured.
The Influence of Non‐Octahedral Slip on Texture Development in FCC Metals
Authors: Bacroix B. , Jonas J. J. 
Published: April 2008

In order to account for the differences observed between low and high temperature
deformation textures, the influence of slip or cross‐slip on planes other than the
{111} is considered in FCC metals. The first set of possible new slip systems treated
is the {100}〈110〉. The dual single crystal yield surface is constructed using a novel
technique, and deformation textures are predicted for rolling and torsion using the
FC‐RC model usually employed at room temperature. The {112} and {110}〈110〉
cross‐slip systems are also considered. The rolling textures obtained when slip and
cross‐slip or only cross‐slip occur are presented. These two cases are first treated on
the assumption of a constant CRSS on all systems and then with the aid of a linear
latent hardening law, which only takes into account the interactions between colinear
systems.It is shown that the concurrent activation of both slip and cross‐slip systems leads
to the presence of three main rolling components: i.e. the Cu, S and brass
orientations, in proportions that vary with the CRSS ratios of the different systems.
These results are in good agreement with experimental observations for high SFE
metals such as aluminum. Some torsion textures are also presented for the case when
both slip and cross‐slip systems are activated. The trends observed in this case are
not as clear as in the case of rolling. However, the orientation, which is the only
component found at high temperatures and high strains in aluminum, is present in
higher proportions than with the classical FC‐RC model, but some other texture
components are also present.
Integrated Ocean Skin and Bulk Temperature Measurements Using the Calibrated Infrared In Situ Measurement System (CIRIMS) and Through-Hull Ports
Authors: Jessup A. T. , Branch R. 
Published: April 2008

Abstract
The design and performance of a shipboard-integrated system for underway skin and bulk temperature is presented. The system consists of the Calibrated Infrared In situ Measurement System (CIRIMS) and through-hull temperature sensors. The CIRIMS is an autonomous shipboard radiometer system that measures the sea surface skin temperature Tskin for validation of satellite-derived sea surface temperature products. General design considerations for shipboard radiometer systems are discussed and the philosophy behind the CIRIMS design is presented. Unique features of the design include a constant temperature housing to stabilize instrument drift, a two-point dynamic calibration procedure, separate sky- and sea-viewing radiometers for simultaneous measurements, and the ability to use an infrared transparent window for environmental protection. Laboratory testing and field deployments are used to establish an estimated error budget, which includes instrumentation and environmental uncertainties. The combination of this testing and field comparison to the Marine-Atmosphere Emitted Radiance Interferometer (M-AERI) and Infrared SST Autonomous Radiometer (ISAR) instruments indicates that the CIRIMS meets the design goal of ±0.10°C accuracy. Temperature and pressure sensors were installed in custom-designed through-hull ports on the NOAA research vessel (R/V) Ronald H. Brown and the University of Washington R/V Thomas G. Thompson to complement the CIRIMS measurements. The ports allow sensors to be installed while the ship is in water and can accommodate a variety of sensors. The combined system provides the ability to measure near-surface temperature profiles from the skin to a depth of 5 m while underway.
Comparisons of Shipboard Infrared Sea Surface Skin Temperature Measurements from the CIRIMS and the M-AERI

Published: April 2008

Abstract
Extensive comparisons are made of the infrared sea surface skin temperature Tskin measured by the Calibrated Infrared In situ Measurement System (CIRIMS) and the Marine-Atmospheric Emitted Radiance Interferometer (M-AERI). Data were collected from four separate deployments on the NOAA research vessel (R/V) Ronald H. Brown and the U.S. Coast Guard (USCG) Polar Sea over a wide range of latitudes and environmental conditions. The deployment time totaled roughly 6 months over a 4-yr period and resulted in over 7000 comparison values. The mean offset between the two instruments showed that CIRIMS consistently measured a lower temperature than the M-AERI, but by less than 0.10°C. This mean offset was found to be dependent upon sky condition, wind speed, and ship roll, which implies the offset is likely due to uncertainty in the emissivity. The CIRIMS Tskin was recomputed using two alterative emissivity values, one based on emissivity measured by the M-AERI and the other based on a wind-speed-dependent model. In both cases, the recomputation of the CIRIMS Tskin significantly reduced the mean offset. The overall standard deviation between the M-AERI and CIRIMS Tskin was 0.16°C, did not significantly depend on environmental conditions, and was within the expected values of instrument and comparison uncertainties. These comparisons demonstrate the success of CIRIMS in achieving good agreement with the M-AERI over a wide range of conditions. The results also highlight the importance of the sea surface emissivity when measuring the ocean surface skin temperature.
Radiative–Convective Feedbacks in Idealized States of Radiative–Convective Equilibrium
Authors: Stephens Graeme L. , van den Heever Susan , Pakula Lyle 
Published: April 2008

AbstractThis paper examines feedbacks between the radiative heating of clouds and convection in the context of numerical radiative–convective equilibrium experiments conducted using both 2D and 3D versions of a cloud-resolving model. The experiments are conducted on a large domain, and equilibria develop as juxtaposed regions of dry and moist air that are connected and sustained by circulations between them. The scales of such variability are large and differ significantly between the 2D and 3D versions of the experiments. Three sensitivity experiments were conducted which, when compared to the control experiment, provide insight into the relative influences of cloud–radiation feedback mechanisms on the equilibrium state achieved. It emerges from the experiments conducted that radiation feedbacks operate via two main pathways, with the radiative heating by high clouds being the governing process of both. The predominant bimodal nature of the moist equilibrium is established by gradients in radiative heating that, in turn, are determined by high cloud differences between wet and dry regions that, in turn, are controlled by convection. Convection, on the other hand, is also influenced by the localized effects of cloud radiative heating by these extended layers of high clouds. The results of the experiments demonstrate how high cloud radiative heating, which is a by-product of the convection itself, provides a feedback that acts to regulate the high clouds produced in the wet convective areas of the equilibrium.
A Global Climatology of Surface Wind and Wind Stress Fields from Eight Years of QuikSCAT Scatterometer Data
Authors: Risien Craig M. , Chelton Dudley B. 
Published: April 2008

AbstractGlobal seasonal cycles of the wind and wind stress fields estimated from the 8-yr record (September 1999–August 2007) of wind measurements by the NASA Quick Scatterometer (QuikSCAT) are presented. While this atlas, referred to here as the Scatterometer Climatology of Ocean Winds (SCOW), consists of 12 variables, the focus here is on the wind stress and wind stress derivative (curl and divergence) fields. SCOW seasonal cycles are compared with seasonal cycles estimated from NCEP–NCAR reanalysis wind fields. These comparisons show that the SCOW atlas is able to capture small-scale features that are dynamically important to both the ocean and the atmosphere but are not resolved in other observationally based wind atlases or in NCEP–NCAR reanalysis fields. This is particularly true of the wind stress derivative fields in which topographic, SST gradient, and ocean current influences on surface winds are plainly visible. Discussions of five example regions are presented to highlight these seasonally recurring small-scale features. It is expected that the SCOW atlas will prove valuable to researchers conducting hydrographic and modeling studies.
Contribution of a Wide-Swath Altimeter in a Shelf Seas Assimilation System: Impact of the Satellite Roll Errors
Authors: Le Hénaff Matthieu , De Mey Pierre , Mourre Baptiste , Le Traon Pierre-Yves 
Published: April 2008

Abstract
The authors investigate the potential qualitative improvement brought by wide-swath, interferometry-based ocean altimetry measurements with respect to classical nadir altimeters in a coastal/shelf data assimilation system. In addition, particular attention is paid to roll errors, which could significantly reduce the expected benefits of wide-swath altimetry. A barotropic, nonlinear free-surface model is set up over the European shelf as part of an ensemble Kalman filter. Experiments assimilating simulated data are performed over the North Sea to test the ability of altimeter configurations to reduce model errors due to the action of meteorological forcing in the presence of bathymetric uncertainties. A simplified wide-swath observation scheme is used, composed of nadir altimeter height plus a nadir-centered cross-track sea level slope measurement. The simplified wide-swath measurements are found to be able to constrain events unsampled by a single nadir altimeter owing to a wider domain of influence in the cross-track direction and the ability to detect cross-track gradients.
Since the satellite-borne interferometer is highly sensitive to the platform behavior, especially satellite roll, experiments taking roll errors into account are then carried out. Whereas observational errors are considered independent in most data assimilation studies, the roll of the platform correlates those errors along the path of the satellite. Despite the large amplitude of the roll errors, the contribution of the wide-swath altimeter in coastal zones remains valuable as long as the roll frequency is known (within Gaussian error) and the assimilation scheme is designed to take observational error correlations into account.
How Transferable is Deming's Approach to a Health and Social Care Setting?
Authors: Patwardhan Anjali , Patwardhan Dhruv 
Published: April 2008

The current consumer demand–led environment poses a threat to the current state of health and social care system. It is expected to keep their sanctities for human values as always, but also provide ‘quality for cost’ services as any other commercial organisation. The structural complexity of health care services and their unique professional and human element of management make it difficult to bring about change by applying any one magic approach. Deming's approach was successfully implemented in the manufacturing industry, and whether this can this be applied to manage quality in the health care sector is question-able. Deming's ‘total quality improvement’ (TQI) approach has been experimented with very little success and satisfaction worldwide. This article analyses the rationale for its non-transferability to the health and social care system, and the causes of its failure in the past. This begs few serious questions: Did we apply management tools that were basically designed for the manufacturing and commercial industries to a service industry like health care inappropriately in the first place? Were these tools applied with sufficient understanding, and were they given enough time before evaluating their suitability? There is a need for this discussion as to why and which part of his approach is and is not transferable to a health and social care setting. Adjustments may be needed either in the approach or the systems to be successful.
National Anglican Identity Formation: An African Perspective
Authors: Fape Michael O. 
Published: April 2008

ABSTRACTAfrica played a prominent role in the formation of earliest Christianity not least in the persons of Cyprian of Carthage and Augustine of Hippo. The Anglican heritage is considered through the experience of the Yoruba people in south-west Nigeria through whom christian faith came to the rest of Nigeria. The Anglicanism which came to the Yoruba was evangelical through the Church Missionary Society, though a key role was played by liberated slaves from Sierra Leone. Contexts in which the gospel is proclaimed and the way it is expressed may change, yet the contents of the gospel do not. A contextualized curriculum thus includes key courses such as biblical studies and systematic theology. It also includes contextual subjects such as African traditional religions and Islam and Christianity. The Church of Nigeria has thus undertaken a thorough review of the curriculum to adequately represent this kind of contextualized theology.
Anglican Identity and Theological Formation in Aotearoa New Zealand
Authors: Te Paa Jenny Plane 
Published: April 2008

ABSTRACTSt John's College Auckland has served the New Zealand church for over 150 years. In 1992 the Anglican Church in New Zealand changed its constitution to give recognition to the Pakeha, Maori and Polynesian groups in the church. The Canon concerning St John's College was also changed to reflect the new Constitutional arrangements. From that time the college was committed to recognizing the two cultural traditions in its leadership and across all aspects of the college's activities and environment. This implied significant curriculum challenges. Some difficult choices have been faced as to the relationship with a secular university and its implications for the presence in the curriculum of Anglican studies. These have been resolved in a way which honours the contextual issues and the tradition of Anglican faith.
Anglican National Identity: Theological Education and Ministerial Formation in Multifaith Malaysia
Authors: Walters Albert Sundararaj 
Published: April 2008

ABSTRACTMalaysia became an independent nation in 1957 and has grown dramatically in prosperity since that time. The main groups in this ethnically diverse nation are Malays (65 per cent) Chinese (26 per cent) and Indians (7.7 per cent). Sixty per cent of the population are Muslim which is the official religion of the nation. Christians represent about 9 per cent of the population and there are 80,000 Anglican members. There has been political pressure against Christians in recent years and there is growing concern about the position of minority religious groups. Anglicans came with the British, though indigenous mission was the work of Indian and Chinese Christians. Theological education is mainly focused on the Seminari Theoloji Malaysia where a holistic curriculum has been developed. A sense of Anglican identity is developing in relation to the context in Malaysia but this has hindered clarity on the nature of the Anglican heritage. The challenges facing the Anglican Church in Malaysia are identified.
Tyndale's Gospel of St John: Translation and the Theology of Style
Authors: Pinti Daniel 
Published: April 2008

ABSTRACTBuilding on Rowan Williams's claims about William Tyndale's importance for English Reformation theology, this paper outlines a theological matrix within which we can situate and interpret Tyndale's translation work. Focusing on Tyndale's translation of the fourth Gospel in his 1534 New Testament, the central claim is that in light of more recent developments in biblical interpretation, the very style of Tyndale's translation has evident theological implications with compelling resonances for contemporary Anglicanism. This analysis of the theology of Tyndale's literary style also attempts to contribute to the ongoing reassessment of Tyndale's reputation. Tyndale's biographer, David Daniell, has lamented that ‘Tyndale as theologian… has been at best neglected and at worst twisted out of shape’, while ‘Tyndale as conscious [literary] craftsman has been… denied’. As a close reading of Tyndale's Gospel of John shows, Tyndale the theologian and Tyndale the craftsman can and should be approached as one and the same.

Kinetic Studies on Complexation Reactions of Lithium Ion with Cryptand C211 in Ionic Liquids by Using 7Li NMR
Authors: Shirai Atsushi , Ikeda Yasuhisa 
Published: April 2008

Abstract
Kinetic studies on complexation reactions of LiI with cryptand C211 in N,N-diethyl-N-methyl-N-(2-methoxyethyl)ammonium bis(trifluoromethylsulfonyl)imide (DEMETFSI) and 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMITFSI) have been carried out using 7Li NMR. It was found that the reaction rates in both solutions depend on concentrations of free LiI and that their kinetic parameters are almost same. From these results, it is proposed that the LiI complexation reactions in DEMETFSI and EMITFSI solutions proceed though bimolecular mechanism.
The OR/MS Ecosystem: Strengths, Weaknesses, Opportunities, and Threats
Authors: Sodhi ManMohan S. , Tang Christopher S. 
Published: April 2008

This paper is dedicated to Arthur Geoffrion, who serves as role model of a great researcher, educator, and practitioner. We believe that research, teaching, and practice are becoming increasingly disengaged from one another in the OR/MS ecosystem. This ecosystem comprises researchers, educators, and practitioners in its core along with end users, universities, and funding agencies. Continuing disengagement will result in OR/MS occupying only niche areas and disappearing as a distinct field even though its tools would live on. To understand the reasons for this disengagement better and to engender discussion among academics and practitioners on how to counter it, we present the ecosystem's strengths, weaknesses, opportunities, and threats. Incorporated in this paper are insights from a cluster of sessions at the 2006 INFORMS meeting in Pittsburgh (“Where Do We Want to Go in OR/MS?”) and from the literature.

Zeitgeschichte zwischen Erinnerung und Politik. Die wissenschaftliche Kommission für deutsche Kriegsgefangenengeschichte, der Verband der Heimkehrer und die Bundesregierung 1957 bis 1975
Authors: Schwelling Birgit 
Published: April 2008

Vorspann
Im Frühjahr 1957 setzte die Bundesregierung eine „Wissenschaftliche Kommission für die Dokumentation des Schicksals der deutschen Kriegsgefangenen des 2. Weltkriegs“ ein. Ging es dem federführenden Vertriebenenministerium darum, Dokumentenmaterial für etwaige Friedensverhandlungen zusammenzustellen, wollte der mitgliederstarke Verband der Heimkehrer, Kriegsgefangenen und Vermisstenangehörigen das Thema der Kriegsgefangenschaft in der bundesdeutschen Erinnerungskultur prominent platzieren. Birgit Schwelling untersucht, wie das von der Kommission vertretene Postulat strenger Wissenschaftlichkeit zunächst mit den „Überlieferungsbedürfnissen“ der Zeitzeugen, dann auch mit den entspannungspolitischen Rücksichten wechselnder Bundesregierungen in Konflikt geriet, die für eine Sekretierung der Dokumentation in ausgewählten Bibliotheken sorgten.

Absztrakt
A pitvari sövényhiány (ASD) percutan eszközös zárása mint alternatíva lépett elő a nyitott szívműtéti megoldás helyett. A szerzők egy 55 éves nő esetét mutatják be, akinél veleszületett secundum típusú ASD miatt Amplatzer-occluder beültetést végeztek. Mellkasi panaszai három nappal az eszköz beültetése után kezdődtek, emiatt kardiológusa echocardiographiát végzett, mely a korábban beültetett eszköz hiányát és a korábbi ASD fennállását látta, majd klinikánkra utalta, ahol mellkasröntgen és mellkas-CT-felvétel készült, melyek az occluder aorta-tuncus brachiocephalicus szögletbe ékelődését igazolták. Extracorporalis szívműtétet indikáltunk az eszköz eltávolítására és a meglévő ASD direkt varrattal történő zárására. Eseménytelen posztoperatív időszak után távozott a beteg otthonába, jó általános állapotban.
