John Dewey's "Wholly Original Philosophy" and Its Significance for Museums

CURATOR THE MUSEUM JOURNAL, Issue 2 2006
George E. Hein
He attempted to construct a philosophical system that incorporated life as it is lived, not in some ideal form. He rejected all dualisms, such as those between thought and action, fine and applied arts, or stimulus and response. An analysis of "experience" (defined as almost synonymous with "culture") is central to Dewey's writing and leads him to emphasize process, continuity, and development, rather than static, absolute concepts. This paper examines the significance of Dewey's educational views for museum exhibitions and education programs, and his complex definitions of relevant concepts, with special emphasis on his interpretation of "experience." Dewey's faith in democracy and his moral philosophy require that the value of any educational activity depends on its social consequences as well as its intellectual content, a proposition that is discussed and applied to museums. This argument suggests that exhibitions and programs can strengthen democracy by promoting skills that improve visitors' ability to become critical thinkers and by directly addressing controversial issues, taking the side of social justice and democracy.

Operative Results without Invasive Monitoring in Patients with Frontal Lobe Epileptogenic Lesions

EPILEPSIA, Issue 10 2001
A. Mariottini
Summary: ,Purpose: To further explore the still controversial issues regarding whether all or most candidates for epilepsy surgery should be investigated preoperatively with invasive long-term video-EEG monitoring techniques (ILTVE). Methods: We studied five patients with intractable seizures since early childhood using the same protocol: clinical evaluation, magnetic resonance imaging (MRI) with fluid-attenuated inversion recovery (FLAIR) sequences, long-term video-EEG (LTVE) monitoring with scalp electroencephalogram (EEG), interictal single photon emission computed tomography (SPECT), positron emission tomography (PET), and neuropsychological testing. The patients' seizures had clinical features suggesting a frontal lobe (FL) origin. MRI scans revealed focal cortical dysplasia (CD) in four patients and a probable gliotic lesion in the fifth. The findings in both PET and SPECT images were congruent with those of the MRI. Scalp LTVE failed to localize the ictal onset, although the data exhibited features suggestive of both CDs and FL seizures. On the basis of these results, surgery was performed with intraoperative corticography, and the cortical area exhibiting the greatest degree of spiking was ablated. Results: Histopathologic study of four of the resected specimens confirmed the presence of CD, whereas in the fifth, there were features consistent with a remote encephaloclastic lesion. There were no postoperative deficits. Seizures in three of the patients were completely controlled at 2,3.5 years of follow-up; a fourth patient is still having a few seizures, which have required reinstitution of pharmacotherapy, and the fifth has obtained 70% control. All patients have had significant improvement in psychosocial measures. For comparison, five patients with generally similar clinical and neuroradiologic features to the previous group underwent preoperative ILTVE monitoring. The surgical outcomes between the two groups have not differed significantly. Conclusions: We conclude that patients with FL epilepsies may be able to undergo successful surgery without preoperative ILTVE monitoring, provided there is high concordance between neuroimaging tests (MRI, SPECT, PET) and the seizure phenotypes, even when routine EEGs and scalp LVTE fail to localize ictal onset unambiguously. The surgical outcomes of these patients generally paralleled those of the other subjects who also had FL epilepsy but who were operated on only after standard ILTVE monitoring. [source]


Actor alignments in the European Union before and after enlargement

EUROPEAN JOURNAL OF POLITICAL RESEARCH, Issue 6 2009
ROBERT THOMSON
What impact has the 2004 enlargement had on legislative decision making in the European Union (EU)? This study answers this question by examining the controversies raised by a broad selection of legislative proposals from before and after the 2004 enlargement. The analyses focus on the alignments of decision-making actors found on those controversies. Member State representatives, the European Commission and the European Parliament vary considerably in the positions they take on controversial issues before and after enlargement. Consistent patterns in actor alignments are found for only a minority of controversial issues. To the extent that consistent patterns are found, the most common involve differences in the positions of Northern and Southern Member States and old and new Member States. The North-South alignment was more common in the EU-15 and reflected Northern Member States' preference for low levels of regulatory intervention. The new-old alignment that has been evident in the post-2004 EU reflects new Member States' preference for higher levels of financial subsidies. This study argues that the persistent diversity in actor alignments contributes to the EU's capacity to cope with enlargement. [source]


Local Government Accounting Standard-setting in Australia: Did Constituents Participate?

FINANCIAL ACCOUNTABILITY & MANAGEMENT, Issue 4 2000
Christine Ryan
The Public Sector Accounting Standards Board (PSASB) has developed accounting standards for the public sector in Australia. A procedural ,due process' has been developed to protect the openness, neutrality and independence of Australian standard-setting both in the private and public sectors. Prior research into constituent participation in the ,due process' for specific cases in the public sector has raised doubts as to whether the ,due process' operated in an open, neutral and independent manner. It has found that account preparers were under-represented in their responses and used less sophisticated lobbying strategies than other respondents. The research also concluded that some constituents had favourable access to the ,due process', and that standard setters did not receive all pertinent information from constituents. This paper examines constituent participation in the ,due process' for the first public sector accounting standard, that for local government (AAS 27). The submissions made on the exposure draft preceding the standard ,ED 50, have been analysed using content analysis. The findings suggest that account preparers were well-represented in their responses and adopted the lobbying strategy of weighting their responses with supporting argument for the most controversial issues. Contrary to prior research, the paper concludes that in the case of ED 50 there is no evidence that the ,due process' failed to operate in an open and neutral manner. [source]


Top-down control of phytoplankton: the role of time scale, lake depth and trophic state

FRESHWATER BIOLOGY, Issue 12 2002
JÜrgen Benndorf
SUMMARY 1.,One of the most controversial issues in biomanipulation research relates to the conditions required for top-down control to cascade down from piscivorous fish to phytoplankton. Numerous experiments have demonstrated that Phytoplankton biomass Top-Down Control (PTDC) occurs under the following conditions: (i) in short-term experiments, (ii) shallow lakes with macrophytes, and (iii) deep lakes of slightly eutrophic or mesotrophic state. Other experiments indicate that PTDC is unlikely in (iv) eutrophic or hypertrophic deep lakes unless severe light limitation occurs, and (v) all lakes characterised by extreme nutrient limitation (oligo to ultraoligotrophic lakes). 2.,Key factors responsible for PTDC under conditions (i) to (iii) are time scales preventing the development of slow-growing inedible phytoplankton (i), shallow depth allowing macrophytes to become dominant primary producers (ii), and biomanipulation-induced reduction of phosphorus (P) availability for phytoplankton (iii). 3.,Under conditions (iv) and (v), biomanipulation-induced reduction of P-availability might also occur but is insufficient to alter the epilimnetic P-content enough to initiate effective bottom-up control (P-limitation) of phytoplankton. In these cases, P-loading is much too high (iv) or P-content in the lake much too low (v) to initiate or enhance P-limitation of phytoplankton by a biomanipulation-induced reduction of P-availability. However, PTDC may exceptionally result under condition (iv) if high mixing depth and/or light attenuation cause severe light limitation of phytoplankton. 4.,Recognition of the five different conditions reconciles previous seemingly contradictory results from biomanipulation experiments and provides a sound basis for successful application of biomanipulation as a tool for water management.

Trends in peptic ulcer pharmacotherapy

FUNDAMENTAL & CLINICAL PHARMACOLOGY, Issue 1 2004
Bülent Sivri
Abstract Considering the diseases of the stomach and duodenum, peptic ulcer has been the one with a significant clinical impact. The pathophysiology of peptic ulcer has centred on an imbalance between aggressive and protective factors. The discovery of Helicobacter pylori as a cause of peptic ulcer has changed our approach greatly towards this disease. Despite the decreasing frequency of H. pylori -induced peptic ulcers, peptic ulcer remains a major clinical problem partly because nonsteroidal anti-inflammatory drug (NSAID)-related ulcers and hospital admissions for ulcer complications associated with NSAIDs have increased in frequency. The interaction between H. pylori and NSAIDs is one of the most controversial issues in peptic ulcer. In this article, current concepts of peptic ulcer etiopathogenesis and the management of peptic ulcer according to the etiology were reviewed. [source]


Optimal treatment of hypertension in the elderly: A Korean perspective

GERIATRICS & GERONTOLOGY INTERNATIONAL, Issue 1 2008
Kwang-Il Kim
With the progression of the aging population, common diseases of the elderly have become the center of attention in most developed countries. Hypertension is one of the most common morbid conditions in the elderly and has a great impact on their health status because it is the main risk factor of cardiovascular and cerebrovascular diseases. However, a considerable amount of uncertainty remains regarding hypertension in the elderly, such as the benefits of hypertension control in oldest-old populations, the optimal level of blood pressure control, and the efficacy of antihypertensive drugs for the prevention of cognitive dysfunction. While there are many controversial issues concerning the optimal management of hypertension in the elderly, the number of elderly hypertensive patients that require treatment is expected to increase due to the aging population. As a result, knowledge regarding the mechanisms of hypertension in the elderly and specific consideration in managing hypertensive elderly patients are needed to improve the clinical outcome. Furthermore, new therapeutic interventions that are aimed at attenuating age-related vascular changes should be investigated, because hypertension in the elderly, especially isolated systolic hypertension has specific characteristics of increased arterial stiffness in most cases.

Validity and utility of the current definition of binge eating

INTERNATIONAL JOURNAL OF EATING DISORDERS, Issue 8 2009
Barbara E. Wolfe PhD, FAAN
Abstract Objective Binge eating, a cardinal symptom of bulimia nervosa (BN) and binge eating disorder (BED), continues to pose challenges in terms of its definition and thus construct validity and clinical utility. This article reviews the available empirical data that support or refute the current DSM-IV-TR defined characteristics of a binge episode. Method A systematic literature review was conducted using Medline/PubMed electronic database on DSM-IV-TR defined binge characteristics and associated attributes. Results Data support the current DSM guidelines indicating that binge episodes typically occur in less than 2 h. Size of binge episodes has variability across BN and BED diagnostic groups. Loss of control (LOC) continues to be a core feature of binge eating. Negative affect is the most widely reported antecedent. Strikingly, little is known about binge episodes among individuals with anorexia nervosa-binge/purge subtype. Discussion Available empirical evidence supports the current DSM duration and LOC attributes of a binge episode in BN and BED. However, a more controversial issues is the extent to which size is important in the definition of a binge episode (e.g., subjective vs. objective episodes) across diagnostic categories and the extent to which binge size informs prognosis, treatment, and clinical outcomes. Further study of binge eating attributes in AN is needed. © 2009 American Psychiatric Association. Int J Eat Disord 2009 [source]


Frame of reference rater training issues: recall, time and behavior observation training

INTERNATIONAL JOURNAL OF TRAINING AND DEVELOPMENT, Issue 2 2003
Sylvia G. Roch
This study investigated three controversial issues regarding frame of reference training (FOR), a type of rater training: (1) Does it improve behavioral recall, (2) Can it be improved by incorporating behavior observation training (BOT), and (3) Can its effects persist over time? Results suggested that even though FOR training increases the number of behaviors recalled, it does not necessarily improve the quality of the recalled behaviors, but a combined FOR + BOT program does improve recall quality. Lastly, results suggested that FOR training can improve rating accuracy, even after a two-week delay between rater training and the rating task. [source]


Red Media, Blue Media: Evidence of Ideological Selectivity in Media Use

JOURNAL OF COMMUNICATION, Issue 1 2009
Shanto Iyengar
We show that the demand for news varies with the perceived affinity of the news organization to the consumer's political preferences. In an experimental setting, conservatives and Republicans preferred to read news reports attributed to Fox News and to avoid news from CNN and NPR. Democrats and liberals exhibited exactly the opposite syndrome,dividing their attention equally between CNN and NPR, but avoiding Fox News. This pattern of selective exposure based on partisan affinity held not only for news coverage of controversial issues but also for relatively "soft" subjects such as crime and travel. The tendency to select news based on anticipated agreement was also strengthened among more politically engaged partisans. Overall, these results suggest that the further proliferation of new media and enhanced media choices may contribute to the further polarization of the news audience. Resumen Los Medios Rojos, los Medios Azules: La Evidencia de la Selectividad Ideológica en el Uso de los Medios Mostramos que la demanda de noticias varía con la percepción de la afinidad con las organizaciones de noticias en las preferencias políticas del consumidor. En un ambiente experimental, conservadores y Republicanos prefirieron leer reportes de noticias atribuidos a la cadena de noticias Fox y evitaron las noticias de CNN y NPR. Los Demócratas y liberales exhibieron el síndrome exactamente opuesto , dividiendo su atención igualmente entre CNN y NPR, pero evitando las noticias de la cadena Fox. Esta pauta selectiva de exposición basada en la afinidad partidaria es sostenida no solo con respecto a la cobertura de noticias de hechos controversiales, sino también con respecto a materias relativamente "blandas" tales como el crimen y el viaje. La tendencia a seleccionar noticias basadas en un acuerdo anticipado fue aumentada también entre los partidarios políticamente más comprometidos. En general, los resultados sugieren que la mayor proliferación de los nuevos medios y las opciones mejoradas de los medios pueden contribuir a una mayor polarización de las audiencias de noticias.

Genetic, physiologic and ecogeographic factors contributing to variation in Homo sapiens: Homo floresiensis reconsidered

JOURNAL OF EVOLUTIONARY BIOLOGY, Issue 6 2006
GARY D. RICHARDS
Abstract A new species, Homo floresiensis, was recently named for Pleistocene hominid remains on Flores, Indonesia. Significant controversy has arisen regarding this species. To address controversial issues and refocus investigations, I examine the affinities of these remains with Homo sapiens. Clarification of problematic issues is sought through an integration of genetic and physiological data on brain ontogeny and evolution. Clarification of the taxonomic value of various ,primitive' traits is possible given these data. Based on this evidence and using a H. sapiens morphological template, models are developed to account for the combination of features displayed in the Flores fossils. Given this overview, I find substantial support for the hypothesis that the remains represent a variant of H. sapiens possessing a combined growth hormone,insulin-like growth factor I axis modification and mutation of the MCPH gene family. Further work will be required to determine the extent to which this variant characterized the population. [source]


THE PHILOSOPHY OF JOSEPH MARGOLIS

METAPHILOSOPHY, Issue 5 2005
Göran Hermerén
Abstract: In this article I focus on some of Joseph Margolis's contributions to medical ethics. I first discuss some of Margolis's normative and metaphysical views on death and abortion, particularly in his early work Negativities, as well as some of his metaphysical assumptions. Then these views and assumptions are related to his theory of persons and, by implication, his theory of culture, set forth in a number of later works. In the course of the discussion, I call attention to some controversial issues of today, such as embryonic stem cell research and the creation of embryos for the sole purpose of research, and ask for Margolis's views on them, given his earlier contributions and assumptions. Finally, I comment on his relativism and his program for research in aesthetics and ethics. [source]


RETHINKING ENDOGENOUS MONEY: A CONSTRUCTIVE INTERPRETATION OF THE DEBATE BETWEEN HORIZONTALISTS AND STRUCTURALISTS

METROECONOMICA, Issue 4 2004
Giuseppe FontanaArticle first published online: 7 OCT 200
ABSTRACT Beyond a widespread agreement on the idea that ,loans create deposits' and ,deposits make reserves', there is much controversy in the endogenous money literature over the workings of the reserve market, the credit market and the financial markets. In this paper a constructive interpretation of the debate between horizontalists and structuralists is suggested and their arguments are taken forward by showing that these controversial issues can be explained rigorously once a single-period,continuation framework is adopted.

The Peritoneal Microcirculation in Peritoneal Dialysis

MICROCIRCULATION, Issue 5 2001
BENGT RIPPE
ABSTRACT This paper deals with the peritoneal microcirculation and with peritoneal exchange occurring in peritoneal dialysis (PD). The capillary wall is a major barrier to solute and water exchange across the peritoneal membrane. There is a bimodal size-selectivity of solute transport between blood and the peritoneal cavity, through pores of radius ,40,50 Å as well as through a very low number of large pores of radius ,250 Å. Furthermore, during glucose-induced osmosis during PD, nearly 40% of the total osmotic water flow occurs through molecular water channels, termed "aquaporin-1." This causes an inequality between 1,, and the sieving coefficient for small solutes, which is a key feature of the "threepore model" of peritoneal transport. The peritoneal interstitium, coupled in series with the capillary walls, markedly modifies small-solute transport and makes large-solute transport asymmetric. Thus, although severely restricted in the blood-to-peritoneal direction, the absorption of large solutes from the peritoneal cavity occurs at a high clearance rate (,1 mL/min), largely independent of molecular radius. True absorption of macromolecules to the blood via lymphatics, however, seems to be occurring at a rate of ,0.2 mL/min. Several controversial issues regarding transcapillary and transperitoneal exchange mechanisms are discussed in this paper. [source]


The perioperative management of children with phaeochromocytoma

PEDIATRIC ANESTHESIA, Issue 5 2000
H.A. Hack MB, MRCP(UK)
Summary The safe anaesthetic management of a child with a phaeochromocytoma requires an understanding of the pathophysiology of the disease, together with a thorough knowledge of its pharmacology, in order to avoid or minimize the potentially harmful cardiovascular changes that may occur during anaesthesia. Although there is a considerable amount of information on the management of the adult with phaeochromocytoma, much less has been written concerning children with the disease. Children differ significantly from adults in the incidence, location, presentation and management of this condition and these differences are discussed here together with some of the more controversial issues of management.

How Electoral Systems Can Influence Policy Innovation

POLICY STUDIES JOURNAL, Issue 4 2010
Salomon Orellana
This paper argues that in certain areas of policy, electoral systems can influence policy innovation (how early countries will adopt certain policies). Electoral systems influence the number of parties that win representation and thereby influence the diversity of perspectives included in the policymaking process. It is argued here that this diversity facilitates elite and public consideration of new issues and ideas, and consequently, it leads to earlier debate and action on these issues and ideas. This dynamic is particularly relevant to controversial issues and ideas that major parties may be hesitant to address and that minor parties may be more incentivized to promote. In this paper, two issues/ideas are considered: extending rights to same-sex couples and making material sacrifices to protect the environment. I show that countries with more proportional electoral systems tend to act earlier to protect the environment and that they tend to be early adopters of civil union legislation. These results are also supported by World Values Survey data showing public preference patterns that support these policy outcomes. [source]


Best practices in the identification of gifted students with learning disabilities

PSYCHOLOGY IN THE SCHOOLS, Issue 5 2001
D. Betsy McCoach
In recent years, researchers and practitioners have become increasingly interested in students who have both learning disabilities and intellectual gifts. Intellectually gifted students are defined as those who demonstrate outstanding ability to grapple with complexity, or superior academic potential. The definition of learning disability states that the level of performance in a particular academic area is substantially below what would be expected based on one's general intellectual ability and that this incongruity cannot be explained by lack of educational opportunity in that academic area. This article explores several controversial issues surrounding the identification of students as both gifted and learning disabled. How does a discrepancy manifest itself in a student who is intellectually gifted? Do gifted students with learning disabilities experience masking effects? How can we effectively identify intellectually gifted students with learning disabilities? In addition, we argue against the use of profile analysis to identify gifted students with learning disabilities. Finally, we propose guidelines for school psychologists to identify students with intellectual gifts and learning disabilities, and we provide suggestions for how to best serve this unique population of students within the school environment. © 2001 John Wiley & Sons, Inc.

Accrual Budgeting: Accounting Treatment of Key Public Sector Items and Implications for Fiscal Policy

PUBLIC BUDGETING AND FINANCE, Issue 2 2006
CARIDAD MARTÍ
Budgeting in accrual terms is one of the most controversial issues in public sector accounting. In this paper, we analyze the accounting treatment of problematic elements of the financial statements when introducing accrual budgeting, and discuss the effects of the analyzed accounting alternatives on fiscal policy. We focus on three pioneer countries in the implementation of accrual budgeting and accounting: the United Kingdom, Sweden, and New Zealand. The accounting standards of the International Public Sector Accounting Standards Board, the European System of Accounts, and the Government Finance Statistics Manual of the International Monetary Fund are taken as benchmarks.

Peer and teacher ratings of third- and fourth-grade children's social behavior as a function of early maternal employment

THE JOURNAL OF CHILD PSYCHOLOGY AND PSYCHIATRY AND ALLIED DISCIPLINES, Issue 4 2003
Lise M. Youngblade
Background:, One of the more controversial issues related to maternal employment in the United States concerns the timing of entry into the workforce and its effect on children, particularly during the first year of the child's life. Some studies show deleterious effects on children, such as increases in aggression and noncompliance, while others document few negative and even positive effects of early employment. Methods:, This study examined the long-term effects of maternal employment during the child's first year of life on the social behavior of 171 third- and fourth-grade children in two-parent families. The moderating effects of child gender and social class were investigated. The extent to which stability in alternative care arrangements statistically explained links between early maternal employment and child outcomes was tested. Results:, After controlling for child gender, and maternal ethnicity, social class, and current employment status, third- and fourth-grade children whose mothers were employed during their first year of life evinced more acting out and less frustration tolerance and were nominated more often by peers for ,hitting' and ,being mean' than children whose mothers were not employed. There was some evidence that these associations were moderated by child gender and social class: boys, but not girls, whose mothers were employed during the first year were subsequently rated by teachers as acting out more than other children, and were also more likely to be nominated by peers for hitting. Higher nominations for hitting were only found in the working class. Finally, there was partial evidence that the number of alternative child-care arrangements during the first year accounted for the links between early maternal employment and subsequent child outcomes. Conclusions:, These results are congruent with extant research that posits a risk of early employment on socioemotional development, but show that this risk is partially attributable to child-care instability.

Guidelines for procedural pain in the newborn

ACTA PAEDIATRICA, Issue 6 2009
Paola Lago
Abstract Despite accumulating evidence that procedural pain experienced by newborn infants may have acute and even long-term detrimental effects on their subsequent behaviour and neurological outcome, pain control and prevention remain controversial issues. Our aim was to develop guidelines based on evidence and clinical practice for preventing and controlling neonatal procedural pain in the light of the evidence-based recommendations contained in the SIGN classification. A panel of expert neonatologists used systematic review, data synthesis and open discussion to reach a consensus on the level of evidence supported by the literature or customs in clinical practice and to describe a global analgesic management, considering pharmacological, non-pharmacological, behavioural and environmental measures for each invasive procedure. There is strong evidence to support some analgesic measures, e.g. sucrose or breast milk for minor invasive procedures, and combinations of drugs for tracheal intubation. Many other pain control measures used during chest tube placement and removal, screening and treatment for ROP, or for postoperative pain, are still based not on evidence, but on good practice or expert opinions. Conclusion: These guidelines should help improving the health care professional's awareness of the need to adequately manage procedural pain in neonates, based on the strongest evidence currently available.
