The Effects of Vestibular Rehabilitation after Bilateral Superior Semicircular Canal Dehiscence: A Case Report  [PDF]
Connor L. Naccarato, Kristen M. Johnson
International Journal of Clinical Medicine (IJCM) , 2017, DOI: 10.4236/ijcm.2017.86042
Abstract: Background and Purpose: Despite the strong body of evidence for vestibular rehabilitation, research is lacking for effective clinical management of patients with superior semicircular canal dehiscence (SSCD) and endolymphatic hydrops (EH). The purpose of this case report is to describe the effects of physical therapy in the treatment of a patient diagnosed with bilateral SSCD. Case Description: The patient was a 56-year-old woman with a long-standing otologic history involving bilateral SSCD and EH. The patient’s body structure and function impairments include constant headaches, dizziness with head rotation and eye movements, sensitivity to sounds and lights, and instability during gait. Her activity limitations include lower extremity dressing, driving, and playing her flute. Her participation restrictions include taking part in social gatherings, going to church, driving longer than 30 minutes, playing with her dogs, and teaching flute lessons. Interventions: Specific interventions included vestibular habituation and adaptation exercises, balance and gait training, and patient education. Physical therapy services were provided for approximately 11 weeks with a frequency of two times per week. Outcomes: After eleven weeks of physical therapy, the patient made improvements on the Lower Extremity Functional Scale (43/80 to 52/80), the Dynamic Gait Index (19/24 to 24/24), the Dizziness Handicap Inventory (86/100 to 68/100), and the Sharpened Romberg (2 seconds to >30 seconds). The patient improved in all her activity limitations and participation restrictions. She was able to play her flute for 20-minute intervals, play with her dogs, partake in social gatherings, and drive for 5 hours without symptoms. The patient had plans to pursue surgical intervention within the next year. Discussion: For a patient with a complex otologic history and a current diagnosis of bilateral SSCD, vestibular rehabilitation was an effective management option. The information from this case can be used to guide the effective treatment of similar patients diagnosed with vestibular dysfunction.
Mapping Mountain Front Recharge Areas in Arid Watersheds Based on a Digital Elevation Model and Land Cover Types  [PDF]
E. E. Bowen, Y. Hamada, B. L. O’Connor
Journal of Water Resource and Protection (JWARP) , 2014, DOI: 10.4236/jwarp.2014.68072
Abstract:

A recent assessment that quantified potential impacts of solar energy development on water resources in the southwestern United States necessitated the development of a methodology to identify locations of mountain front recharge (MFR) in order to guide land development decisions. A spatially explicit, slope-based algorithm was created to delineate MFR zones in 17 arid, mountainous watersheds using elevation and land cover data. Slopes were calculated from elevation data and grouped into 100 classes using iterative self-organizing classification. Candidate MFR zones were identified based on slope classes that were consistent with MFR. Land cover types that were inconsistent with groundwater recharge were excluded from the candidate areas to determine the final MFR zones. No MFR reference maps exist for comparison with the study’s results, so the reliability of the resulting MFR zone maps was evaluated qualitatively using slope, surficial geology, soil, and land cover datasets. MFR zones ranged from 74 km2 to 1547 km2 and accounted for 40% of the total watershed area studied. Slopes and surficial geologic materials that were present in the MFR zones were consistent with conditions at the mountain front, while soils and land cover that were present would generally promote groundwater recharge. Visual inspection of the MFR zone maps also confirmed the presence of well-recognized alluvial fan features in several study watersheds. While qualitative evaluation suggested that the algorithm reliably delineated MFR zones in most watersheds overall, the algorithm was better suited for application in watersheds that had characteristic Basin and Range topography and relatively flat basin floors than areas without these characteristics. Because the algorithm performed well to reliably delineate the spatial distribution of MFR, it would allow researchers to quantify aspects of the hydrologic processes associated with MFR and help local land resource managers to consider protection of critical groundwater recharge regions in their development decisions.

Probability of default and probability of excellence, an inverse model of rating. One more tool to overcome the crisis: an empirical analysis
Marco Muscettola,Francesco Naccarato
Business Systems Review , 2013, DOI: 10.7350/bsr.v06.2013
Abstract: After rated as "excellent firms" which in 2010 showed good profitability and a solid financial balance, this essay aims to explore the possibility that a rating model already focused on bankruptcy prediction may also be a valuable tool for the selection of firms that after three years could turn to a state of excellence. Furthermore, the test is carried out and completed even starting from the opposite side: it detects the opportunity of a model calibrated on the prediction of successful firms to provide accurate results in the calculation of the probability of default. In this paper we empirically examine the determinants of a predictive econometric model, in a time frame of three years, using the statistical technique of logistic regression on a panel of 5,000 North Italian SMEs over the period 2007-2010.
Internal Resource Audit for Strategists—A Proposal  [PDF]
Tom Connor
iBusiness (IB) , 2011, DOI: 10.4236/ib.2011.33038
Abstract: It is the purpose of this article to suggest a structured approach to internal resource audit, which, whilst of necessity general-purpose in design, would be capable of adaptation to particular company cases. Consequently this paper does not aim at theory development, but to make a conceptual contribution to the art and practice of management. It will, however, offer some criticism of current theory from a management perspective.
Development and Psychometric Validation of the Dementia Attitudes Scale
Melissa L. O'Connor,Susan H. McFadden
International Journal of Alzheimer's Disease , 2010, DOI: 10.4061/2010/454218
Abstract: This study employed qualitative construct mapping and factor analysis to construct a scale to measure attitudes toward dementia. Five family caregivers, five professionals, and five college students participated in structured interviews. Qualitative analysis of the interviews led to a 46-item scale, which was reduced to 20 items following principal axis factoring with two different samples: college students ( ) and certified nursing assistant students ( ). Confirmatory factor analysis was then conducted with another sample of college students ( ). The final scale, titled the Dementia Attitudes Scale (DAS), essentially had a two-factor structure; the factors were labeled “dementia knowledge” and “social comfort.” Total-scale Cronbach's alphas ranged 0.83–0.85. Evidence for convergent validity was promising, as the DAS correlated significantly with scales that measured ageism and attitudes toward disabilities (range of correlations = 0.44–0.55; mean correlation ). These findings demonstrate the reliability and validity of the DAS, supporting its use as a research tool. 1. Intoduction A “new culture” of dementia care [1, page 136] has been embraced by long-term care residences, adult day programs, support groups, and other programs and services devoted to promoting and sustaining life quality for persons living with dementia. This new culture construes personhood as “a standing or status bestowed upon one human being, by others, in the context of relationship and social being” [1, page 8]. An alternative to the biomedical view of dementia as a collection of neuropsychological symptoms reflecting brain pathology, this psychosocial perspective affirms the unique personal histories of individuals living with dementia in particular social environments. Employing an experimental design, Fritsch et al. [2] showed that staff working with residents using the TimeSlips creative story-telling method in 5 nursing home facilities had more positive views of persons with dementia at the end of a 10-week period than staff who had engaged in their usual activities at 5 control facilities. Because participation in creative engagement programs enables persons with dementia to reveal preserved abilities and insights about the world, these programs may also help families and friends to view residents in a different light. Finally, with more newly retired persons answering the call for civic engagement, community volunteers may become involved in innovative creative engagement programs like Memories in the Making [3] and TimeSlips [4]. These creative activities promote
Temperature Effects on Phosphorus Release from a Biosolids-Amended Soil
Maria L. Silveira,George A. O'Connor
Applied and Environmental Soil Science , 2013, DOI: 10.1155/2013/981715
Abstract: This study was designed to evaluate the effects of temperature on the potential leachable P pool and distribution of chemical P forms in a biosolids-amended soil. A P-deficient Spodosol was incubated with seven biosolids and inorganic P fertilizer at 20 and 32°C for 90 days. Amendments were applied to provide a total P concentration of 112?mg?kg?1 soil, which correspond to a field application of ~224?kg?P?ha?1. Cumulative P mass leached during the 90?d study for any P source was <2% of the applied P, but greater cumulative P mass was released from the biological P removal and composted biosolids than from the heat-dried materials. Increasing temperature (20 to 32°C) generally decreased cumulative P mass leached, suggesting greater soil affinity to retain P at 32°C than at 20°C. In a static incubation experiment (no leaching), soil water-extractable P concentrations were reduced over time, but no temperature effect was observed. Similarly, P distribution among the various fractions was not affected by temperature. The relatively great ability of the soil to sorb P masked differences in biosolids properties and the potential impacts of temperature on P lability. Additional work using low P-sorbing soils is warranted. 1. Introduction Biosolids can provide essential nutrients to plant and improve soil chemical, physical, and biological properties [1]. However, repeated biosolids applications based on plant N requirements supply P in excess of crop requirements, resulting in soil P accumulation. Environmental concerns associated with the buildup of soil P and potential losses of P movement to water bodies via surface runoff, vertical leaching, and erosion exist. Although P is typically immobile in most soils, coarse-textured soils are prone to P transport [2]. Florida Spodosols are particularly susceptible to P leaching due to the lack of reactive minerals, low Fe and Al oxides, and organic matter concentrations in surface horizons [3]. Moreover, poorly drained Spodosols associated with relatively shallow water tables intercepted by drainage ditches increase the potential risks of P edge-field losses. Phosphorus lability in biosolids-treated soils depends on the forms of P is initially present in the biosolids and the characteristics of the soil receiving the residual. The wastewater treatment processes strongly influence the chemistry and P pools in biosolids [4]. For instance, biological P removal (BPR) processes can increase P extractability and runoff losses [5, 6]. Conversely, biosolids treated with Al and Fe or heat-dried materials generally exhibit
Nearside-farside theory of differential cross sections : resummation of a partial wave series involving Legendre polynomials
C. Noli,J. N. L. Connor
Physics , 2003,
Abstract: We report a new resummation procedure for the partial wave series (PWS) representation of the scattering amplitude, when a basis set of Legendre polynomials is used for the expansion. The effect of the resummation is to remove from the PWS the factor containing alpha and beta. The resummed scattering amplitude is then exactly decomposed into the sum of a nearside (N) subamplitude and a farside (F) subamplitude. We make two applications of the NF resummed theory: to elastic angular scattering in a strongly absorptive collision and to a state-to-state differential cross section for the I + HI > IH + I reaction. In both applications, we can understand the physical origin of structure in the angular scattering for suitable choices of alpha, beta and r.
Numerical Evaluation of Cuspoid and Bessoid Oscillating Integrals for Applications in Chemical Physics
J. N. L. Connor,C. A. Hobbs
Physics , 2004,
Abstract: Oscillating integrals often arise in the theoretical description of phenomena in chemical physics, in particular in atomic and molecular collisions, and in spectroscopy. A computer code for the numerical evaluation of the oscillatory cuspoid canonical integrals and their first-order partial derivatives is described. The code uses a novel adaptive contour algorithm, which chooses a contour in the complex plane that avoids the violent oscillatory and exponential natures of the integrand and modifies its choice as necessary. Applications are made to the swallowtail canonical integral and to a bessoid integral.

Abstract: objective: analyze the treatment satisfaction and impact on patients with localized prostate cancer. methods: one-hundred and eighty patients, with mean age of 60 years, were divided into three groups: group i - 100 patients submitted to radical retropubic prostatectomy (rrp), group ii - 40 patients who underwent radiotherapy (rt), and group iii - 40 healthy men. a questionnaire was applied to the groups to assess physical and psychological changes 18 months after treatment. the investigational tool was based on two questionnaires; first: sf-36 (short form health survey), second: fact-p (functional assessment cancer therapy). results: in group i, 70% never used pads, 5% presented with complete urinary incontinence, and 10% reported occasional stool leakage. in group ii, 85% did not use pads and 5% reported two pads a day; 15% reported stool leakage or intestinal cramps. sexual dysfunction was similar in both groups: 75% of the surgical group and 72.5% of the radiotherapy group reported erectile dysfunction. in the control group, 40% reported erectile dysfunction; 10% reported occasional stool leakage and none had changes regarding the overall treatment-related satisfaction. seventy-eight percent of the rrp group and 77.5% of the rt group reported being happy respecting satisfaction with the accepted or chosen treatment, and affirmed that would choose it again. conclusions: the assessment of treatment-related satisfaction determines the treatment tolerability. this study?s results did not show any significant changes in this issue between both treatment modalities (p0.05).
How well do blood folate concentrations predict dietary folate intakes in a sample of Canadian lactating women exposed to high levels of folate? An observational study

Abstract: The relationship between blood folate concentrations and dietary folate intakes, determined by weighed food records, were assessed in a sample of predominantly university-educated lactating women (32 ± 4 yr) at 4-(n = 53) and 16-wk postpartum (n = 55).Median blood folate concentrations of all participants were well above plasma and RBC folate cut-off levels indicative of deficiency (6.7 and 317 nmol/L, respectively) and all, except for 2 subjects, were above the cut-off for NTD-risk reduction (>906 nmol/L). Only modest associations existed between total folate intakes and plasma (r = 0.46, P < 0.001) and RBC (r = 0.36, P < 0.01) folate concentrations at 16-wk postpartum. Plasma and RBC folate values at 16-wk postpartum correctly identified the quartile of folate intake of only 26 of 55 (47%) and 18 of 55 (33%) of subjects, respectively. The mean RBC folate concentration of women consuming 151–410 μg/d of synthetic folate (2nd quartile of intake) did not differ from that of women consuming >410 μg/d (3rd and 4th quartile).Folate intakes, estimated by food composition tables, and blood folate concentrations are not predictive of each other in Canadian lactating women exposed to high levels of folate. Synthetic intakes > 151–410 μg/d in these women produced little additional benefit in terms of maximizing RBC content. More studies are needed to examine the relationship between blood folate concentration and NTD risk. Until data from such studies are available, women planning a pregnancy should continue to consume a daily folic acid supplement of 400 μg.Folic acid supplementation during the periconceptional period is effective in reducing the risk of neural tube defects (NTDs) [1-5]. However, the proportion of Canadian women that report consuming a folic acid-containing supplement during the periconceptional period is low ranging between 17 – 28% [6-9]. Similar rates are documented even among women who are knowledgeable about the health benefits of consuming folic acid
