Impact of a Fram Strait cyclone on ice edge, drift, divergence, and concentration: Possibilities and limits of an observational analysis

This study aims at the determination of a Fram Strait cyclone track and of the cyclone's impact on ice edge, drift, divergence, and concentration. A 24 h period on 13–14 March 2002 framed by two RADARSAT images is analyzed. Data are included from autonomous ice buoys, a research vessel, Special Sensor Microwave Imager (SSM/I) and QuikSCAT satellite, and the operational European Centre for Medium‐Range Weather Forecasts (ECMWF) model. During this 24 h period the cyclone moved northward along the western ice edge in the Fram Strait, crossed the northern ice edge, made a left‐turn loop with 150 km diameter over the sea ice, and returned to the northern ice edge. The ECMWF analysis places the cyclone track 100 km too far west over the sea ice, a deviation which is too large for representative sea ice simulations. On the east side of the northward moving cyclone, the ice edge was pushed northward by 55 km because of strong winds. On the rear side, the ice edge advanced toward the open water but by a smaller distance because of weaker winds there. The ice drift pattern as calculated from the ice buoys and the two RADARSAT images is cyclonically curved around the center of the cyclone loop. Ice drift divergence shows a spatial pattern with divergence in the loop center and a zone of convergence around. Ice concentration changes as retrieved from SSM/I data follow the divergence pattern such that sea ice concentration increased in areas of divergence and decreased in areas of convergence.

Injectable opiate prescribing in Cornwall

Aims and MethodTo compare local practice with national guidelines, examine the areas of divergence, and establish complication rates for methadone and diamorphine. Fifty-one patients from Cornwall treated with injectable methadone or diamorphine were interviewed using a standard questionnaire.ResultsFewer problems were reported by individuals using injectable diamorphine, though for both drugs intramuscular injection was more problematic than intravenous injection. Injections into the groin were common, as was problem drinking.Clinical ImplicationsIntramuscular administration of medications may be more likely to cause abcesses or cellulitis. Ongoing groin injecting and alcohol misuse is common, but should probably be tolerated if other harm reduction benefits accrue. It may be prohibitively expensive to set up injecting rooms in rural parts of the UK and future policy should reflect this.

Treatment Time, Chronic Inflammation, and Hemodynamic Stability: The Overlooked Parameters in Hemodialysis Quantification

Decades after the introduction of chronic maintenance hemodialysis, the optimal means of quantifying dialysis dose remains controversial. Differences of opinion in the international dialysis community lead to substantial diversity in everyday clinical practice. Several studies suggest that the well-recognized international mortality differences in hemodialysis populations may result from these divergent approaches to dialysis care. One of the main areas of divergence is the different degree of reliance on dialysis clearance when prescribing dialysis. The "clearance approach" implies that treatment quality is primarily dependent on efficient removal of uremic toxins as estimated by dialytic urea clearance. Urea can be rapidly removed by high efficiency dialysis in a relatively short time. The main alternative to this strategy is the "time approach" based on the recognition that longer or more frequent dialysis provides benefits beyond increasing urea removal. Some of the putative benefits are more effective volume and blood pressure control, better maintenance of hemodynamic stability because of slower ultrafiltration and removal of uremic toxins that do not behave like urea. Recently, chronic inflammation has been proposed to be an important predictor of outcome in dialysis patients. Inflammatory markers are commonly elevated in chronic renal failure and levels of these seem to correlate with malnutrition, maintenance of residual renal function, and volume control. The relationships between dialysis clearance, treatment time, chronic inflammation, volume control, and hemodynamic stability are explored in this review. We propose that a better understanding of these complex relationships may provide opportunities for improving outcomes of maintenance hemodialysis patients.

Supergranules over the solar cycle

Context. The origin of supergranulation has not been understood yet. Contradictory results have been obtained in the past concerning the relation between supergranule properties (mostly cell size) and the solar cycle. Aims. We propose to study the variation in supergranule cell sizes and velocity fields over the solar cycle, as well as the intensity variation inside supergranules. Methods. We define supergranule cells from maps of horizontal velocity field divergences. The flow fields are derived from MDI/SOHO intensity maps. The intensity variation in supergranules are compared to the variation inside granules resulting from a numerical simulation. The variation in these profiles with the cell size and over the solar cycle is also analysed. Results. We find that cell sizes are smaller on average at cycle maximum. We also find that the slope between Log (Vrms )a nd Log (R) is weakly correlated with the spot number (i.e. the global activity level) but anti-correlated with the local magnetic field. We also confirm the decrease in the intensity variation from cell centre to the boundary, which puts a lower limit on the temperature variation of 0.57 ± 0.06 K. This temperature difference is of 1.03 ± 0.05 K when considering the areas of strongest divergence and strongest convergence. We observe a strong similarity in the intensity variation inside supergranules and granules. A significant variation with the cell size is observed, also similar to that in granules, but the variation over the solar cycle is not significant. Conclusions. The sign of the variation in supergranule cell sizes over the solar cycle is in agreement with what can be expected from the influence of the magnetic field. The observed intensity variations show that a common process could be the origin of both granules and supergranules.

Opinions of married women about potential causes and triggers of intimate partner violence against women. A cross-sectional investigation in an Iranian city

BackgroundPopulation-based perception studies on potential causes and triggers of intimate partner violence against women (IPVAW) may enlighten context-relevant primary preventive actions in settings where data are limited. This study, conducted in one specific city, deals with married women's opinions concerning potential causes and triggers of IPVAW and seeks to highlight areas of consensus and divergence in the views.MethodsA convenient sample of women aged 25–45 years and married for at least 5 years was consecutively recruited in the 48 public health centres of Kermanshah city, where free health services are provided to mothers and children under 6 years old. Respondents were individually interviewed on site by trained and experienced female interviewers (response rate 94.3%). A structured pilot-tested questionnaire was used that consisted mainly of closed questions about individual assessment of the extent to which various items could be regarded as a potential cause, a potential trigger or a potential consequence of IPVAW. Individual item frequencies were compiled and the association between socio-demographic attributes of the spouses and also respondents' prior exposure to violence and women answers was explored.ResultsFor most factors covered, women mainly "agreed" or "agreed very much" about their potential as a trigger or a cause of IPVAW; agreements were stronger for individual-related potential causes. Generally, women's socio-demographic characteristics and prior victimisation did not much affect the opinions they expressed. For some triggers however, women's own occupation and their husband's educational level affected how much in agreement they were.ConclusionThe women interviewed consider that most potential causes and triggers proposed may, at some point in a relationship, engender IPVAW. In the main, their views are not much altered by their own and their husbands' socioeconomic position or their prior victimisation. It remains to be seen whether married men and, for that matter, even women married for a shorter duration or from other settings will answer in a similar manner.

Demography, Culture, and Policy: Understanding Japan's Low Fertility

Insights into the causes of Japan's prolonged and sharp fall in total fertility rate come from comparing Japan with France. The two countries share dirigiste administrative approaches, family policy reform undertaken under the auspices of pragmatic right wing parties and justified on pronatalist grounds, and involvement of demographic experts in crafting and shepherding such policies. But the countries differ with respect to their total fertility rates (France 1.98, Japan 1.29) and the effectiveness of their family policies. Thus comparing them can help identify areas of divergence that might explain these differences and assist in the project of theory building. Several salient explanations are rooted in Japan's labor market: it exacts high opportunity costs from parents who interrupt their careers to raise children, keeps ideal workers from having much time for their families, assumes and reinforces a traditional gender ideology, and hires few young workers into good jobs.

Self-Study of Values, Beliefs, and Conflict of Interest

Observation and survey of values, beliefs, and conflicts of interest. To study the values, beliefs, and potential conflicts of interest that the Neck Pain Task Force brought to their deliberations. Researchers’ values and beliefs were studied to uncover areas of divergence and to develop guiding principles to assist decision making. An observer used direct observation and survey of the Neck Pain Task Force, facilitated discussion, and developed a “disclosure tool” to collect information about relationships between researchers, funders, and others with a vested interest in the outcome. Clinicians and research methodologists brought different imperatives to the research process. Clinicians focused on offering useful advice, whereas methodologists guarded investigative rigor to ensure that evidence actually supported advice. Group conflict did not polarize along “clinical discipline lines.” The Advisory Committee had greater impact when given a clear task and time to work as a group. The Neck Pain Task Force agreed on a set of “guiding principles,” which became an overarching doctrine to guide their work. The disclosure questionnaires described relationships between Neck Pain Task Force members and other entities that might have had a financial interest in the topic. This study describes a process used to assess values, beliefs, and conflicts of interest among members of a scientific task force, and how this was used to create “guiding principles” to assist the research team in deliberations, particularly when conflict arose. Most members of the Neck Pain Task Force had potential conflicts of interest with various stakeholders, but there was marked diffusion of these potential conflicts and no evidence that any funder or other vested interest stakeholder was likely to have a significant impact on the deliberations or conclusions of the Neck Pain Task Force.

Translating modals between English and Arabic

Although central to many disciplines, modality has not received adequate treatment in the field of contrastive studies of English-Arabic translation. Since there are no neat Arabic counterparts to English modals, the only valid arguments for comparison are, therefore, the semantic-pragmatic ones. The current study investigates the relationship between modality and implicature in English-Arabic translation. The main argument is based on the premise that the speaker’s choice of modal expressions signals both the degree and type of involvement a speaker has in the content of the message, and consequently the interpretation of textual implicatures. The study shows that there are other textual means of expressing modality in Arabic that go beyond the immediate verbal construction. In some contexts, the whole discoursal effect will determine the degree of deontic or epistemic modality. The paper also explores shifts and transitions in translating modal patterns between English and Arabic with a view to assessing their overall effect. The examples cited show that the shift in rendering ST modals often entails an alteration in the possible interpretation of their meanings in the TT. In sensitive contexts, such as religious texts, political treaties and negotiations, business deals and court testimonies, some changes may have grave consequences. Although an analysis of the areas of convergence and divergence may help identify common causes of translation errors, the notion of ‘indeterminacy’ remains paramount in translating texts between these two languages. The paper concludes with a pragmatic strategy for the interpretation of modals in context.

Accounting Convergence of Intangibles: Value Relevance of R&D Accounting Treatment

The rapid globalization of markets has resulted in further acceleration of the worldwide convergence of accounting standards, including the development of high-quality and globally consistent accounting standards for both domestic and cross-border financial reporting. Prior studies report that earnings value relevance of U.S. companies is decreasing, and the decline is partially attributable to the immediate expensing of intangibles, like research and development (R&D). Being one of the areas of divergence, accounting for R&D was highlighted as one of the seven short-term convergence projects by the FASB and IASB. Australia's adoption of IFRS in 2005 presents an empirical setting to evaluate the value relevance of different accounting treatments for R&D, and ultimately assist financial accounting standard setters in the U.S. and abroad in finding an appropriate accounting treatment for R&D.

Large scale variation in Enterococcus faecalis illustrated by the genome analysis of strain OG1RF

Inhibitory functioning across ADHD subtypes: Recent findings, clinical implications, and future directions

Although growing consensus supports the role of deficient behavioral inhibition as a central feature of the combined subtype of ADHD (ADHD/C; Barkley 1997 Psychol Bull 121:65-94; Nigg 2001 Psychol Bull 127:571-598), little research has focused on how this finding generalizes to the primarily inattentive subtype (ADHD/I). This question holds particular relevance in light of recent work suggesting that ADHD/I might be better characterized as a disorder separate from ADHD/C (Diamond 2005 Dev Psychopathol 17:807-825; Milich et al. 2001 Clin Psychol Sci Pract 8:463-488). This article describes major findings in the area of inhibitory performance in ADHD and highlights recent research suggesting important areas of divergence between the subtypes. In particular, preliminary findings point to potential differences between the subtypes with respect to how children process important contextual information from the environment, such as preparatory cues that precede responses and rewarding or punishing feedback following behavior. These suggestive findings are discussed in the context of treatment implications, which could involve differential intervention approaches for each subtype targeted to the specific deficit profiles that characterize each group of children. Future research avenues aimed toward building a sound theoretical model of ADHD/I and a better understanding of its relation to ADHD/C are also presented. Specifically, investigators are encouraged to continue studying the complex interplay between inhibitory and attentional processes, as this area seems particularly promising in its ability to improve our understanding of the potentially distinct pathologies underlying the ADHD subtypes.

Resolution of student complaints in higher education institutions

This paper examines the processes whereby students may bring complaints against higher education institutions. It stresses that a right to redress of grievance is fundamental to the relationship between students and universities. It focuses on internal complaints procedures and discusses the findings from a survey of a representative sample of institutions of which nearly two thirds (25 in total) responded with statistical and other data on the grounds of complaint, the ethnicity and other characteristics of complainants, and the outcome of adjudications. It reveals areas of commonality and divergence in practice and raises concerns about the fairness and accessibility of the procedures. The paper also includes discussion of the process for the external adjudication of student complaints established under the Higher Education Act 2004 and the way that complaints progress to it. The paper discusses the case for reform of higher education institutions’ student complaints procedures, which are surprisingly unregulated, including the introduction of a more independent element such as ‘campus ombudsmen’.

The Emerging Strategic Partnership between India and the EU: A Critical Appraisal

For a long time, the relations between India and the EU have been largely informed by economics without any similar significant engagement at the political level. In recent times however, amongst others, the changing external environment, the EU's emerging profile as a global actor and India's growing importance both regionally and globally warranted the need for greater political dialogue and cooperation between the two sides. What followed therefore was the formalisation at the highest level of the EU's political dialogue with India and its institutionalisation into a meaningful summit‐level partnership leading to a strategic partnership. Areas of divergence and challenges remain but the opportunities that have surfaced are significant and deserving of attention. This article critically analyses the growing strategic partnership between India and the EU in the light of both these realities.

E-Government services in local governments a study of development in Swedish municipalities

AbstractThis article presents a study concerning e-Government services at local governments in Sweden. The purpose of the study is to investigate and critically analyse the development of e-Services in Swedish municipalities and through interviews collect, compare and assess data about actual local e-Government services in Sweden in order to find areas of assimilation and divergence. Based on a sample of 24 municipalities in Sweden, the results show that the development and implementation of e-Services are in their infancy and only a few e-Services have been implemented yet. E-Services offered today are basal and primary and closely connected to citizens' daily life. It is difficult to identify many clear and distinct patterns in the development; however, some minor patterns can be identified. The development projects identified in the study are, in most cases, detached projects for the development and implementation of e-Services. The nature of many of the projects today resembles projects for learning r...

The Elimination of Congenital Syphilis: A Comparison of the Proposed World Health Organization Action Plan for the Elimination of Congenital Syphilis With Existing National Maternal and Congenital Syphilis Policies

Building upon a critical assessment of national policies, programs, and treatment options, the World Health Organization (WHO) recently developed an action plan for the elimination of congenital syphilis (CS). The objective of the review was to identify areas of commonality or divergence between the national strategies and the WHO plan, thereby helping to target the development of national-level policies in light of the forthcoming recommendations of the proposed WHO action plan to eliminate CS. The 4 strategic pillars of the proposed WHO action plan were used as a comparative framework to examine the policy, programmatic, and monitoring components of a sample of 14 existing national-level congenital or maternal control policies. The countries were chosen to represent a range of resource and prevalence levels. The majority of countries do not meet every element proposed in the WHO action plan. Political commitment (pillar 1) across the 14 countries is varied. CS elimination goals were rare but all had universal screening. Linkages to appropriate case management services were identified in 11 countries, although a national governing body was not generally evident. Efforts to increase and improve access to care (pillar 2) were noted in 8 countries with recommendations to ensure all pregnant women were screened and treated. Low-resource settings have formed international partnerships. Guidelines for the diagnosis and treatment of pregnant women and partners (pillar 3) found in high-resource settings were lacking in low-resource and high CS prevalence countries. Surveillance programs were active in 10 countries while comprehensive details on monitoring and evaluation (pillar 4) components including proxy CS indicators were unavailable for nearly all. The elimination of CS can be achieved through the implementation of a series of proven measures but requires technical support, funding, and a commitment among political forces, health officials, and the public to prevent and treat all CS cases and help countries reach their Millennium Development Goals. Stronger partnerships with clearly defined responsibilities should be developed among agencies responsible for national STI control, HIV/AIDS control, and Making Pregnancy Safer initiatives to ensure the universal coverage of CS control interventions.

Managing Bone Parameters in Dialysis Patients: International Guideline Conflicts

The linkage between bone parameters (calcium, phosphate, parathyroid hormone) and cardiovascular death in dialysis patients has led to a major resurgence in interest in this area of nephrological practice. Two major groups have recently published extensive guidelines for clinical practice in this area--the National Kidney Foundation's Kidney Disease Outcomes and Quality Initiative from the United States, and the Caring for Australasians with Renal Impairment group from Australia and New Zealand. There are some important differences in their recommendations, which reflect variations in local clinical practice, reimbursement systems, and interpretation of the medical literature. Two areas of divergence are highlighted in this editorial--use of vitamin D and its analogs, and use of phosphate binders. Readers of guidelines such as these need to be careful to interpret such recommendations in the context of the realities of their local clinical practice and availability of therapies.

Vaccine-Induced T-Cell Responses Against HCV: One Step Taken, More to Follow

Exploring the determinants of success/failure of the advertising agency‐firm relationship

PurposeThis paper aims to focus on the advertising agency‐firm relationship and aims at understanding and analysing its dynamics. In particular, it digs deep into the reasons behind success and failure of the relationship and attempts to unveil their determinants. This investigation is deemed important because a breaking of the advertising agency‐firm relationship is costly for both parties.Design/methodology/approachAn exploratory study is conducted among partners of the relationship in a Tunisian small to medium‐sized business context. In‐depth interviews were conducted among key executives from the ad agency industry and from clients. Content analysis made it possible to extract factors related to ad agency performance, others related to client management, and still others related to interactive processes involved in the relationship.FindingsResults led to the development of a theoretical framework summarising the three components of the relationship. These are performance of the ad agency, internal policy of the firm, and interpersonal factors. This framework is deemed relevant for both ad agencies and firms in understanding the dynamics of the relationship and in managing eventual conflicts.Originality/valueThe originality of the research lies in the fact that it focuses on the interactive aspects of the relationship and takes into account not only the role of the advertising agency but also that of the client in developing and maintaining such a relationship. This approach allows one to unveil areas of convergence and areas of divergence between both parties' roles perceptions.

Genomic Databases and International Collaboration

Recent years have witnessed a key development within biomedicine—namely, the move from genetic to genomic research. Genomic research, which operates at the level of the whole genome rather than individual genes, requires a powerful new set of research tools, resources and supporting technologies. Having moved from DNA sequence mapping to the use of haplotypes, the next advances in our understanding of disease risk and health may well be achieved through the study of “normal” genomic variation across whole populations. Such studies require not only samples and data, but also highly sophisticated, substantial database infrastructures to support them. Longitudinal and largely epidemiological in nature, these population-scale genomic database resources are designed to serve a multiplicity of specific research projects at both national and international levels. Current ethical guidance in the area of genetic research promotes the need for international collaboration. Yet, is international genomic research collaboration possible considering both the scientific and structural differences between national approaches to governing genomic databases and associated population biobanks? A review of existing norms at the international level—in particular, around benefit sharing and access to data—and their application in different countries, reveals areas of both convergence and divergence. But, most of all, it reveals the need for international harmonisation in order to secure interoperability and the public participation, trust and investment in such large initiatives that are crucial to their success.
