GOTTFREDSON Research Summary: Study randomly assigned 235 offenders to drug treatment court (DTC) or "treatment as usual." Analyses of official records collected over a two-year follow-up period show that DTC is reducing crime in a population of drug-addicted offenders. DTC subjects who participated in treatment were significantly less likely to recidivate than were both untreated drug court subjects and control subjects. Policy Implications: Continued enthusiasm for DTCs is warranted. Both sanctions and treatment are important elements of the DTC model. However, DTCs will not necessarily result in cost reductions because DTC and control cases are incarcerated for approximately equal numbers of days. Implementation fidelity is important, and DTCs can be strengthened if they engage a higher percentage of their clients in drug treatment. [source] ON THE EFFECTIVENESS OF FISCAL POLICY AS AN INSTRUMENT OF MACROECONOMIC POLICYECONOMIC AFFAIRS, Issue 1 2009Philip Arestis This paper demonstrates that fiscal policy is an effective and essential instrument of stabilisation macroeconomic policy. This is particularly so if it is co-ordinated with monetary policy, especially in the current worldwide economic situation.

[source] EFFECTIVENESS OF CHLORINE AND NISIN-EDTA TREATMENTS OF WHOLE MELONS AND FRESH-CUT PIECES FOR REDUCING NATIVE MICROFLORA AND EXTENDING SHELF-LIFE,JOURNAL OF FOOD SAFETY, Issue 4 2002DIKE O. UKUKU ABSTRACT Efficacy of nisin-EDTA treatments as a sanitizing treatment for reducing native microflora of whole melons and extending shelf-life of fresh-cut pieces was compared to chlorine treatments. Whole cantaloupe and honeydew melons were washed with water, nisin (10 ,g/mL)-EDTA (0.02 M), or 200 ppm chlorine for 5 min at , 20C before fresh-cut preparation and storage at 5C for 15 days with periodic microbiological sampling. In addition, some fresh-cut pieces were washed with 10 ,g/mL nisin-EDTA or 50 ppm chlorine for 1 min before storage. Changes in appearance, odor, overall acceptability and the shelf-life of the minimally processed fresh-cut melons were investigated. Preliminary studies indicated that water washes, EDTA (0.002 to 0.2 M) or nisin (5 to 10 ,g/mL) were not effective in reducing the microflora of whole melon when used individually. Nisin-EDTA and chlorine treatments were significantly (P < 0.05) more effective in reducing native microflora than water washes. Nisin-EDTA treatments were significantly (P < 0.05) more effective than chlorine in reducing populations of yeast and mold and Pseudomonas spp. on whole melon surfaces but were not as effective as chlorine treatments for reducing aerobic mesophilic bacteria, lactic acid bacteria and total gram-negative bacteria. Microbial contaminants on fresh-cut pieces washed with 50 ppm chlorine or nisin-EDTA were further reduced. However, microbial populations increased throughout refrigerated storage irrespective of treatments. Odor, appearance, and overall acceptability ratings for cantaloupe and honeydew fresh-cut pieces treated with nisin-EDTA or chlorine were not significantly (P > 0.05) different from each other throughout the storage period (15 to 21 days). However, both treatments led to significantly (P < 0.05) improved ratings compared to the controls for the fresh-cut pieces at 9 to 12 days of storage and thereafter. The results of this study suggest that treatments with nisin-EDTA before and after fresh-cut processing would improve the quality and extend the shelf-life of fresh-cut melon. [source] A COMPARISON OF THE EFFECTIVENESS OF HEDONIC SCALES AND END-ANCHOR COMPRESSION EFFECTSJOURNAL OF SENSORY STUDIES, Issue 2010HARRY T. LAWLESS ABSTRACT Three experiments were conducted to compare the relative performance of hedonic scaling methods, including the labeled affective magnitude (LAM) scale. In the first study, three versions of the LAM were used to evaluate 20 phrases that described diverse sensory experiences. One scale was anchored to "greatest imaginable like/dislike for any experience" and another used the "greatest imaginable like" phrase of the LAM but with the interior phrases repositioned relative to "any experience." The scale anchored to "any experience" showed a smaller range of scale usage and lower statistical differentiation, relative to the LAM scale, with the repositioned scale intermediate. Two further experiments compared the LAM to the nine-point hedonic scale, an 11-point category scale using the LAM phrases, and to a three-label line scale, a simplified version of the LAM with only the end phrases and the neutral center-point phrase. All scales showed similar differentiation of juices in the second study and sensory experience phrases in the third. A modest advantage for the LAM scale in the second experiment did not extend to the third study. Researchers should be careful in the choice of high end anchors for hedonic scales, as a compressed range of scale usage may result in lower product differentiation. PRACTICAL APPLICATIONS Hedonic scales for food acceptability are widely used in new product development for consumer testing and in food preference surveys. A desired goal of efficient sensory evaluation testing is the ability of tests to differentiate samples on the basis of scale data, in this case scales commonly used for food acceptability and preference testing. Scales which are able to differentiate products more effectively are less likely to lead to Type II error in experimentation, in which true differences between products are not detected. Such errors can lead to lost opportunities for product improvements or to enhanced chances for taking undetected risks in the case of false parity conclusions. [source] EFFECTIVENESS OF CATEGORY AND LINE SCALES TO CHARACTERIZE CONSUMER PERCEPTION OF FRUITY FERMENTED FLAVOR IN PEANUTSJOURNAL OF SENSORY STUDIES, Issue 2 2006J.L. GREENE ABSTRACT Fruity fermented (FF) flavor is a common off-flavor in peanuts resulting from high-temperature curing. The 9-point hedonic scale is the most widely used scale to determine consumer acceptance; however, research has indicated that line scales may provide equal reliability and greater sensitivity. The objectives of this study were to characterize consumer perception of FF flavor in peanuts and to compare the effectiveness of the two scale types. Consumers (n = 208) evaluated control (no FF), low-intensity (1.0) FF and high-intensity (3.0) FF peanut pastes for the strength/intensity of roasted peanut flavor (RPF), sweet taste (ST), fresh peanut flavor (FPF) and overall liking (OV) using randomly assigned ballots. Sensitivity in defining consumer perception of off-flavor in peanuts was greater with use of line scales than with the hedonic scale. The line scale indicated that FF flavor in peanuts, even at low intensity, negatively impacted OV and further identified significantly lower RPF and FPF perception by consumers. The hedonic scale identified only a difference in FPF and was not sensitive enough to show a difference in OV. [source] COST EFFECTIVENESS OF VEGETATIVE FILTER STRIPS AND INSTREAM HALF-LOGS FOR ECOLOGICAL RESTORATION,JOURNAL OF THE AMERICAN WATER RESOURCES ASSOCIATION, Issue 5 2006Emmanuel A. Frimpong ABSTRACT: This paper presents the results of cost effectiveness (CE) analysis of vegetative filter strips (VFS) and instream half-logs as tools for recovering scores on a fish Index of Biotic Integrity (IBI) in the upper Wabash River watershed (UW) in Indiana. Three assumptions were made about recovery time for IBI scores (5,15, and 30 years) and social discount rates (1, 3, and 5 percent), which were tested for sensitivity of the estimated CE ratios. Effectiveness of VFS was estimated using fish IBIs and riparian forest cover from 49 first-order to fifth-order stream reaches. Half-log structures had been installed for approximately two years in the UW prior to the study and provided a basis for estimates of cost and maintenance. Cost effectiveness ratios for VFS decreased from $387 to $277 per 100 m for a 1 percent increase in IBI scores from first-to fifth-order streams with 3 percent discount and 30-year recovery. This cost weighted by proportion of stream orders was $360. The ratio decreased with decreasing time of recovery and discount rate. Based on installation costs and an assumption of equal recovery rates, half-logs were two-thirds to one-half as cost-effective as VFS. Half-logs would be a cost-effective supplement to VFS in low order streams if they can be proven to recover IBI scores faster than VFS do. This study provides baseline data and a framework for planning and determining the cost of stream restoration. [source] CONTINGENCIES IN THE EFFECTS OF PAY RANGE ON ORGANIZATIONAL EFFECTIVENESSPERSONNEL PSYCHOLOGY, Issue 3 2009SVEN KEPES The degree of pay spread can influence many organizational level outcomes (e.g., workforce productivity and organizational performance), but empirical studies are inconsistent about the directionality of the effect. We argue that it is not simply the width of the pay range but also the factors responsible for the width that explain the effects of the pay range on employee and organizational outcomes. We expect that when wider pay ranges are attributable to the use of performance-based pay, the effects of the pay range on performance are positive, but narrower pay ranges attributable to performance-based pay reduce this effect substantially. By contrast, wider pay ranges attributable to politically based pay should have negative effects on performance, and this effect should be weakened when the pay ranges are narrower. Data from a sample of motor carriers generally support our predictions. Although wider pay ranges have positive effects, the results reveal a complex pattern of relationships among the basis of pay allocations and pay range width on the one hand and workforce productivity and organizational performance on the other. Implications for future compensation and strategic human resource management research are discussed. [source] EMPLOYEES THAT THINK AND ACT LIKE OWNERS: EFFECTS OF OWNERSHIP BELIEFS AND BEHAVIORS ON ORGANIZATIONAL EFFECTIVENESSPERSONNEL PSYCHOLOGY, Issue 4 2003STEPHEN H. WAGNER A model of the psychological experience of employee ownership in work groups was developed to investigate antecedents (participation in a 401 (k) program and a climate of self-determination) and consequences (employee attitudes and financial performance) of psychological ownership. Based on data from a large retail organization, results showed that working in a climate supporting self-determination and 401(k) participation were positively related to the level of ownership beliefs in the 204 work groups studied. Ownership beliefs were positively related to ownership behaviors and employees' attitudes toward the organization, whereas ownership behaviors were positively related to financial performance. Implications of psychological ownership for organizational behavior and performance are discussed. [source] ASSESSING THE INCREMENTAL VALIDITY OF TEAM CONSENSUS RATINGS OVER AGGREGATION OF INDIVIDUAL-LEVEL DATA IN PREDICTING TEAM EFFECTIVENESSPERSONNEL PSYCHOLOGY, Issue 3 2001BRADLEY L. KIRKMAN Using data collected from 98 work teams, empowerment levels were assessed based on the aggregation of individual team member ratings as well as on a team consensus approach utilized after aggregation. These 2 methods of measuring team empowerment were then compared on their ability to predict manager ratings of team effectiveness on 4 dimensions. Findings demonstrated that the consensus method of measuring team empowerment explained significantly greater variance in team effectiveness than did the aggregation method alone. We discuss implications for team research and practice based on these findings and include a discussion on when using consensus after aggregation may be most appropriate. [source] THE EFFECTIVENESS OF AN ORGANIZATIONAL-LEVEL ORIENTATION TRAINING PROGRAM IN THE SOCIALIZATION OF NEW HIRESPERSONNEL PSYCHOLOGY, Issue 1 2000HOWARD J. KLEIN This quasi-experimental field study examined the impact of attending a voluntary, organizational-level new employee orientation training program on organizational socialization. Six content dimensions of socialization were measured before and 1 to 2 months following orientation training for a sample of 116 new employees in a variety of occupations. Results revealed that employees attending the orientation training were significantly more socialized on 3 of the 6 socialization content dimensions (goals/values, history, & people) than employees who did not attend the training. Employees attending the orientation training also had significantly higher levels of affective organizational commitment than nonattendees, a relationship that was fully mediated by the socialization content dimensions, primarily goals/values, and history. [source] POSTING MULTIPLE PRICES TO REDUCE THE EFFECTIVENESS OF CONSUMER PRICE SEARCH,THE JOURNAL OF INDUSTRIAL ECONOMICS, Issue 2 2007NORMAN J. IRELAND In a model of competition with imperfect consumer price information and incomplete price search, some consumers may end up comparing prices originating from the same supplier: either because one firm sets multiple prices or because a group of firms colludes. This leads to added monopoly power for these firms, and average prices in the mixed strategy equilibrium become higher. There is a shift in welfare from consumers to producers, both with exogenous and endogenous consumer search behaviour. However consumers might search more or less with multiple prices. The implications for the price-setting equilibrium, competition policy and recent judgements are considered. [source] COMPETITION AND RESOURCE EFFECTIVENESS IN EDUCATION,THE MANCHESTER SCHOOL, Issue 1 2007DAVID MAYSTON This paper examines the impact of competition in the markets for teachers and for housing on the long-standing issue of the influence of school resourcing on educational attainment. The existence of such competition is found to imply not only downward bias in many earlier empirical estimates of the role of resources in the educational production function, but also powerful general equilibrium effects, especially for the impact of relative levels of school resources on the distribution of relative levels of educational attainment across individual schools, that highlight the importance of how resources are distributed across individual schools.

[source] RE-EXAMINING THE EFFECTIVENESS OF STABILISATION POLICYAUSTRALIAN ECONOMIC PAPERS, Issue 4 2007ANTHONY J. MAKIN This paper develops an alternative international macroeconomic model for evaluating the effectiveness of fiscal and monetary policy in stabilising national income under fixed and floating exchange rates. It encompasses national output and income, saving, investment, money and capital flows and linkages between the exchange rate, price levels and real interest rates consistent with international parity conditions. It demonstrates that the nature of government spending is pivotal to the effectiveness of fiscal policy, revealing that, ceteris paribus, higher public consumption expenditure contracts national income and depreciates the exchange rate, whereas higher productive public investment spending has opposite effects. The framework also shows that the effectiveness of fiscal and monetary policy as macroeconomic policy instruments is not ultimately dependent on the exchange rate regime. [source] Incorporating Maintenance Effectiveness in the Estimation of Dynamic Infrastructure Performance ModelsCOMPUTER-AIDED CIVIL AND INFRASTRUCTURE ENGINEERING, Issue 3 2008Chih-Yuan Chu Specifically, we consider state-space specifications of autoregressive moving averages with exogenous inputs models to develop deterioration and inspection models for infrastructure facilities, and intervention analysis to estimate transitory and permanent effects of maintenance, for example, performance jumps or deterioration rate changes. To illustrate the methodology, we analyze the effectiveness of an overlay on a flexible pavement section from the AASHO Road Test. The results show the effect of the overlay on improvements both on surface distress, that is, rutting and slope variance, as well as on the pavement's underlying serviceability. The results also provide evidence that the overlay changes the pavement's response to traffic, that is, the overlay causes a reduction in the rate at which traffic damages the pavement. [source] Effects of back care education in elementary schoolchildrenACTA PAEDIATRICA, Issue 8 2000G Cardon The purpose of this study was to investigate the effects of a back care education programme, consisting of six sessions of 1 h each, in fourth- and fifth-grade elementary schoolchildren. Testing consisted of a practical performance and a back care knowledge test. Forty-two subjects and 36 controls performed a pre-test and were tested within 1 wk after the programme. To monitor effects and follow-up effects on a larger sample, 82 different pupils were tested within 1 wk after the programme and 116 other children 3 mo after. Both larger samples were compared with one group of 129 controls. Interrater reliability for the test items of the practical assessment was high; intraclass correlation coefficients varied from 0.785 to 0.980. In the pre/post design study, interaction between time and condition was significant for the sum score of the practical assessment and for the knowledge test (p < 0.001), with higher scores for the intervention group (15% improvement for the knowledge test score, 31.6% for the practical sum score). Significantly higher sum scores for the knowledge test and for all practical assessment items were found in the intervention groups, tested within 1 wk and 3 mo after the programme, in comparison with the control group (p <0.001). Conclusion: The effectiveness of a primary educational prevention programme on back care principles was demonstrated in this study. Effectiveness, long-term outcomes and behavioural changes need further evaluation to optimize back care prevention programmes for elementary schoolchildren.

TURNER Lake Wales Ridge (Florida); especies en peligro; índice de protección; Lista Roja IUCN; matorral Abstract:,Measuring the effectiveness of reserve networks is essential to ensure that conservation objectives such as species persistence are being met. We devised a new approach for measuring the effectiveness of land conservation in protecting rare and threatened species and applied it to an ecosystem of global significance. We compiled detailed global distributional data for 36 rare and threatened plants and animals found in the Lake Wales Ridge ecosystem in central Florida (U.S.A.). For each species, we developed a set of protection indices based in part on criteria used to categorize species for the World Conservation Union's Red List. We calculated protection indexes under three different conservation scenarios: a past scenario, which assumed recent, major land-acquisition efforts never occurred; a current scenario, which assumed no additional areas are saved beyond what is currently protected; and a targeted scenario, which assumed all of the remaining areas targeted for protection are eventually acquired. This approach enabled us to quantify the progress, in terms of reduced risk of extinction, that conservationists have made in protecting target species. It also revealed the limited success these land-acquisition efforts have had in reducing those extinction risks associated with loss of habitat or small geographic ranges. Many species of the Lake Wales Ridge will remain at high risk of extinction even if planned land-acquisition efforts are completely successful. By calculating protection indexes with and without each site for all imperiled species, we also quantified the contribution of each protected area to the conservation of each species, enabling local conservation decisions to be made in the context of a larger (global) perspective. The protection index approach can be adapted readily to other ecosystems with multiple rare and threatened species. Resumen:,La cuantificación de la efectividad de las redes de reservas es esencial para asegurar que objetivos, como la persistencia de especies, se cumplan. Diseñamos un nuevo método para medir la efectividad de la conservación de tierras en la protección de especies raras y amenazadas y lo aplicamos a un ecosistema de importancia global. Compilamos datos detallados de la distribución global de 36 especies raras y amenazadas de plantas y animales que se encuentran en el ecosistema de la Lake Wales Ridge en el centro de Florida (E.U.A.). Para cada especie desarrollamos un conjunto de índices de protección basado parcialmente en criterios utilizados para clasificar especies para la Lista Roja de la Unión Mundial para la Naturaleza. Calculamos los índices de protección bajo tres escenarios de conservación distintos: un escenario pasado, que asumía que los esfuerzos recientes de adquisición de tierras nunca ocurrieron; un escenario actual, que asumía que no se protegen áreas adicionales a las ya conservadas; y un escenario deseado, que asumía que todas las áreas consideradas para ser protegidas son adquiridas eventualmente. Este método nos permitió cuantificar el progreso, en términos de la reducción del riesgo de extinción, en la protección de las especies obtenido por conservacionistas. También reveló el éxito limitado de los esfuerzos de adquisición de tierras en la disminución de los riesgos de extinción asociados con la pérdida de hábitat o con rangos geográficos pequeños. Se pronosticó que muchas especies de la Lake Wales Ridge permanecerán en alto riesgo aun si los esfuerzos de adquisición de tierra planificados son completamente exitosos. Al calcular los índices de protección con y sin cada sitio para todas las especies en peligro, también cuantificamos la contribución de cada área protegida a la conservación de cada especie, lo que permite que las decisiones de conservación se tomen en el contexto de una perspectiva mayor (global). El método del índice de protección se puede adaptar fácilmente a otros ecosistemas con múltiples especies raras y amenazadas.

[source] Effectiveness of Conservation Targets in Capturing Genetic DiversityCONSERVATION BIOLOGY, Issue 1 2003Maile C. Neel We used empirical data from four rare plant taxa to assess these consequences in terms of how well allele numbers ( all alleles and alleles occurring at a frequency openface>0.05 in any population ) and expected heterozygosity are represented when different numbers of populations are conserved. We determined sampling distributions for these three measures of genetic diversity using Monte Carlo methods. We assessed the proportion of alleles included in the number of populations considered adequate for conservation, needed to capture all alleles, and needed to meet an accepted standard of genetic-diversity conservation of having a 90,95% probability of including all common alleles. We also assessed the number of populations necessary to obtain values of heterozygosity within ±10% of the value obtained from all populations. Numbers of alleles were strongly affected by the number of populations sampled. Heterozygosity was only slightly less sensitive to numbers of populations than were alleles. On average, currently advocated conservation intensities represented 67,83% of all alleles and 85,93% of common alleles. The smallest number of populations to include all alleles ranged from 6 to 17 ( 42,57% ), but <0.2% of 1000 samples of these numbers of populations included them all. It was necessary to conserve 16,29 ( 53,93% ) of the sampled populations to meet the standard for common alleles. Between 20% and 64% of populations were needed to reliably represent species-level heterozygosity. Thus, higher percentages of populations are needed than are currently considered adequate to conserve genetic diversity if populations are selected without genetic data. Resumen: Cualquier acción de conservación que preserve algunas poblaciones y no otras tendrá consecuencias genéticas. Utilizamos datos empíricos de cuatro taxones de plantas raras para evaluar estas consecuencias en términos de lo bien representados que están los números de alelos ( todos los alelos ocurriendo a una frecuencia>0.05 en cualquier población ) y la heterocigosidad esperada cuando se conservan diferentes números de poblaciones. Las distribuciones de muestreo de estas tres medidas de la diversidad genética fueron determinadas utilizando métodos Monte Carlo. Evaluamos la proporción de alelos incluida en números de poblaciones: consideradas adecuadas para la conservación; requeridas para capturar todos los alelos; y las requeridas para alcanzar un estándar de conservación de diversidad genética aceptable del 90,95% de probabilidad de incluir todos los alelos comunes. También evaluamos el número de poblaciones necesarias para obtener valores de heterocigosidad que caigan dentro de ±10% del valor obtenido de todas las poblaciones. Los números de alelos fueron afectados significativamente por el número de poblaciones muestreadas. La heterocigosidad solo fue ligeramente menos sensible a los números de poblaciones de lo que fueron los alelos. Las intensidades de conservación propugnadas actualmente representaron en promedio el 67,83% de todos los alelos y el 85,93% de los alelos comunes. El menor número de poblaciones para incluir a todos los alelos varió de 6 a 17 ( 42,57% ), pero <0.2% de 1000 muestras de esos números de poblaciones los incluyó a todos. Fue necesario conservar de 16 a 29 ( 53,93% ) de las poblaciones muestreadas para alcanzar el estándar para los alelos comunes. Se requirió entre 20% y 64% de las poblaciones para representar la heterocigosidad a nivel de especie confiablemente. Por lo tanto, se requieren mayores porcentajes de poblaciones que los actualmente considerados adecuados para conservar la diversidad genética si las poblaciones son seleccionadas sin datos genéticos. [source] New Product Development Decision-Making Effectiveness: Comparing Individuals, Face-To-Face Teams, and Virtual Teams,DECISION SCIENCES, Issue 4 2001Jeffrey B. Schmidt Abstract A total of 411 subjects participated in two decision-making experiments in order to examine the effectiveness of new product development project continuation decisions. Using escalation of commitment theory, in Study 1, individual versus face-to-face team decision-making effectiveness was compared. Study 2, an extension of Study 1, compared the new product development decision-making effectiveness of individuals, face-to-face teams, and virtual teams. A virtual team is a geographically and temporally dispersed and electronically communicating work group. In Study 2, the virtual teams communicated asynchronously via groupware technology. Our findings suggest that teams make more effective decisions than individuals, and virtual teams make the most effective decisions. [source] A Structural Analysis of the Effectiveness of Buying Firms' Strategies to Improve Supplier PerformanceDECISION SCIENCES, Issue 1 2000Daniel R. Krause Many manufacturing firms have increased the amount of component parts and services they outsource, while refocusing on their core capabilities. Outsourcing parts and services to independent, external suppliers means that suppliers' performance is increasingly critical to the long-term success of these buying firms. Buying firms are increasingly using disparate supplier development strategies to improve supplier performance including supplier assessment, providing incentives for improved performance, instigating competition among suppliers, and direct involvement of the buying firm's personnel with suppliers through activities such as training of suppliers' personnel. Using resource-based theory, internalization theory, and structural equation modeling, we examine the impact of these supplier development strategies on performance. We conclude that direct involvement activities, where the buying firm internalizes a significant amount of the supplier development effort, play a critical role in performance improvement. [source] Improving the Efficiency and Effectiveness of Grading Through the Use of Computer-Assisted Grading RubricsDECISION SCIENCES JOURNAL OF INNOVATIVE EDUCATION, Issue 1 2008Linda Anglin ABSTRACT This study tests the use of computer-assisted grading rubrics compared to other grading methods with respect to the efficiency and effectiveness of different grading processes for subjective assignments. The test was performed on a large Introduction to Business course. The students in this course were randomly assigned to four treatment groups based on the grading method. Efficiency was measured by the professor's time to grade the assignments; effectiveness was measured by a student satisfaction survey. Results suggest that the computer-assisted grading rubrics were almost 200% faster than traditional hand grading without rubrics, more than 300% faster than hand grading with rubrics, and nearly 350% faster than typing the feedback into a Learning Content Management System. Results also seemed to indicate that the use of a computer-assisted grading rubric did not negatively affect student attitudes concerning the helpfulness of their feedback, their satisfaction with the speed with which they received their feedback, or their satisfaction with the method by which they received feedback.

[source] Effectiveness of limited cone-beam computed tomography in the detection of horizontal root fractureDENTAL TRAUMATOLOGY, Issue 3 2009vanç Kamburo Root fractures were created in the horizontal plane in 18 teeth by a mechanical force and fragments were relocated. Another 18 intact teeth with no horizontal root fracture served as a control group. Thirty-six teeth were placed in the respective empty maxillary anterior sockets of a human dry skull in groups three by three. Intraoral radiographs were obtained in three different vertical views by utilizing Eastman Kodak E-speed film, CCD sensor, RVG 5.0 Trophy and a PSP sensor Digora, Optime. Cone beam CT images were taken with a unit (3D Accuitomo; J Morita MFG. Corp, Kyoto, Japan). Three dental radiologists separately examined the intraoral film, PSP, CCD and cone beam CT images for the presence of horizontal root fracture. Specificity and sensitivity for each radiographic technique were calculated. Kappa statistics was used for assessing the agreement between observers. Chi-square statistics was used to determine whether there were differences between the systems. Results were considered significant at P < 0.05. Cone beam CT images revealed significantly higher sensitivities (P < 0.05) than the intraoral systems between which no significant differences were found. Specificities did not show any statistically significant differences between any of the four systems. The kappa values for inter-observer agreement between observers (four pairs) ranged between 0.82,0.90 for the 3DX evaluations and between 0.63,0.71 for the different types of intraoral images. Limited cone beam CT, outperformed the two-dimensional intraoral, conventional as well as digital, radiographic methods in detecting simulated horizontal root fracture. [source] Effectiveness of dental trauma education for elementary school staffDENTAL TRAUMATOLOGY, Issue 2 2008Judy D. McIntyre Using a newly developed reliable survey instrument, we tested our elementary school staff participants about TDI before (time0), immediately after (time1), and three months after (time2) the intervention. Schools were randomized into three groups: no intervention/control (C), pamphlets (P), and pamphlets + lecture (P + L). Outcomes of interest were TDI knowledge over time relative to the interventions vs controls. Statistical analysis involved a repeated measures linear model. At time0, TDI knowledge was low among all three groups. At time1, knowledge increased among all groups and is given by P > P+L > C. For time2 vs time1, the P + L group retained the knowledge while in both the C and P groups the knowledge level decreased. Between time1 and time2, significant differences were found between both intervention groups when compared with the control (P vs C and P + L vs C: both P < 0.05). In summary, both P and P + L groups significantly improved TDI knowledge among elementary school staff, and this difference held up over time. These interventions have the potential to improve TDI management by elementary school staff when faced with such injuries. [source] Effectiveness of mindfulness-based cognitive therapy as an adjuvant to pharmacotherapy in patients with panic disorder or generalized anxiety disorderDEPRESSION AND ANXIETY, Issue 7 2009Yong Woo Kim M.D. Abstract Background: Mindfulness-based cognitive therapy (MBCT) has been widely used to treat patients with depressive disorder to prevent relapse. The objective of this study was to examine the effectiveness of newly developed MBCT program as an adjuvant to pharmacotherapy in the treatment of patients with panic disorder or generalized anxiety disorder. Methods: Forty-six patients with panic disorder or generalized anxiety disorder were assigned to either MBCT or an anxiety disorder education (ADE) program for a period of 8 weeks. The Hamilton Anxiety Rating Scale (HAM-A), Hamilton Depression Rating Scale (HAM-D), Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), and Symptom Checklist-90-Revised (SCL-90-R) were used to assess the patients at 0 week and after the two programs had been running for 2, 4, and 8 weeks. Results: The MBCT group demonstrated significantly more improvement than the ADE group according to all anxiety (HAM-A, p<0.01; BAI, p<0.01; anxiety subscale of SCL-90-R, p=0.01) and depression (HAM-D, p<0.01; BDI, p<0.01; depression subscale of SCL-90-R, p<0.01) scale scores. The obsessive-compulsive and phobic subscales of the SCL-90-R also showed significantly more improvement in the MBCT group. However, no significant improvement was observed in the MBCT group versus the ADE group in terms of the somatization, interpersonal sensitivity, paranoid ideation, or psychoticism subscale scores of the SCL-90-R. Conclusions: MBCT may be effective at relieving anxiety and depressive symptoms in patients with panic disorder or generalized anxiety disorder. However, well-designed, randomized controlled trials are needed. Depression and Anxiety, 2009. © 2009 Wiley-Liss, Inc. [source] The Safety and Effectiveness of Single-Pass Erbium:YAG Laser in the Treatment of Mild to Moderate PhotodamageDERMATOLOGIC SURGERY, Issue 8 2004David K. Avram MD Background. There are several treatment modalities for mild to moderate photodamage. The demand for effective treatments with minimal side effects has increased. Objective. The objective of this study was to determine the effectiveness of short-pulsed erbium:YAG laser in treating mild to moderate photodamage. Methods. Twenty patients were treated with the short-pulse erbium:YAG laser on the face and neck. One pass was given over the entire face with two to three passes over the perioral and periorbital regions. Patients were evaluated for improvement of pigmentary irregularities, skin texture, and fine wrinkles. All side effects were recorded at follow-up visits. Two lasers were used, Sciton and Cynosure CO3, under local anesthesia. Results. There was a 58% reduction in pigment irregularities and a 54% improvement in skin texture. There was minimal improvement in fine wrinkles with one pass. Two and three passes resulted in a 50% reduction in wrinkles. The procedure was minimally painful. Side effects included 3 to 5 days of erythema and edema. Patients returned to work within 3 days on average. There were no infections. Patient satisfaction with the procedure was rated as very good. There was no difference in efficacy or adverse effects with either laser. Conclusions. One-pass short-pulse erbium:YAG laser in treating photodamage of the face and neck is safe and effective. There are minimal side effects and patients heal within 3 to 5 days. [source] | |||||||||||||||||||||||||||||||
