On the Pointwise Bishop–Phelps–Bollobás Property for Operators
Authors: Dantas Sheldon , Kadets Vladimir , Kim Sun Kwang , Lee Han Ju , Martín Miguel 
Published: October 2018

AbstractWe study approximation of operators between Banach spaces $X$ and $Y$ that nearly attain their norms in a given point by operators that attain their norms at the same point. When such approximations exist, we say that the pair $(X,Y)$ has the pointwise Bishop–Phelps–Bollobás property (pointwise BPB property for short). In this paper we mostly concentrate on those $X$, called universal pointwise BPB domain spaces, such that $(X,Y)$ possesses pointwise BPB property for every $Y$, and on those $Y$, called universal pointwise BPB range spaces, such that $(X,Y)$ enjoys pointwise BPB property for every uniformly smooth $X$. We show that every universal pointwise BPB domain space is uniformly convex and that $L_{p}(\unicode[STIX]{x1D707})$ spaces fail to have this property when $p>2$. No universal pointwise BPB range space can be simultaneously uniformly convex and uniformly smooth unless its dimension is one. We also discuss a version of the pointwise BPB property for compact operators.

Published: October 2018

Abstract. Hall current variations in different time sectors during six magnetic storms
from the summer seasons in 2003 and 2005 (Ritter, 2018) are examined, namely three storms in the
day–night meridional sector and three storms in the dawn–dusk sector. The
sequence of the phenomena, their structure and positions, and the strength of the
polar (PE) and the auroral (AE) Hall electrojets were investigated using
scalar magnetic field measurements obtained from the CHAllenging Minisatellite Payload (CHAMP) satellite in
accordance with the study of Ritter et al. (2004a). We analyzed the correlations of
the PE and AE as well as the obtained regression relations of the magnetic
latitude MLat and the electrojet current intensity I with auroral and ring
current activity, the interplanetary magnetic field, and the Newell et al. (2007)
coupling function for the state of the solar wind. The following typical
characteristics of the electrojets were revealed: The PE appears in the daytime sector at MLat ∼80∘–73∘, with a westward
or an eastward direction depending on the interplanetary magnetic field (IMF) By component (By < 0 nT or By > 0 nT).
Changes in the current flow direction in the PE can occur repeatedly during the
storm, but only due to changes in the IMF By orientation.
The PE increases with the intensity of the IMF By component from
I∼0.4 A m−1
for By∼0 nT up to I∼1.0 A m−1 for By∼23 nT.
The MLat position of the PE does not depend on the direction and intensity
of the By component. There is no connection between MLat and I in the PE and the symmetric part
of the magnetospheric ring current (index SymH).
There is a correlation between I in the PE and the AsyH index, but only a very weak
interconnection of this index with the MLat of the PE. Substorms occurring before the storm's main phase are accompanied
by the appearance of an eastward electrojet (EE) at MLat ∼64∘ as well as that of a westward electrojet (WE).
In the nighttime sector, a WE appears at MLat ∼64∘.
During the main phase both electrojets persist.
The daytime EE and the nighttime WE shift toward sub-auroral latitudes of
MLat ∼56∘ and grow in intensity up to I∼1.5 A m−1.
The WE is then located about 6∘ closer to the pole than the EE during
evening hours and about 2∘–3∘ closer during daytime hours.

Authority of today’s aldermen
Today’s aldermen work in several different environments. They should reckon with society but also with local council, the municipal organisation, the mayor and fellow aldermen. The tasks are very clear, but how an alderman completes these tasks is very personal. For alderman Rensen his authority starts with trust. Personal and sincere relationships are the key for Rensen. His goal is to connect society to local politics and reduce the gap between the two. It is of great importance to be aware of your position and authority as an alderman. By means of this essay, he would like to give you a glimpse into his world as a social-demoratic alderman and the way in which he applies his core values in his daily work.

Published: October 2018

Many studies indicates that entrepreneurial mindset is a critical factor in the accumulation, evaluation and selection of the knowledge which can lead an individual into potential business opportunities thereby enhancing entrepreneurial outcomes such as firm performance. This study examined the effect of entrepreneurial mindset on the performance of small and medium scale enterprises in Benue State. The focus of the research was to measure the entrepreneurs’ mindset exhibited through innovativeness, creativity, business alertness and risk taking and how these attributes contributed to the performance of SMEs. The research focused on a population of 650 small and medium scale enterprises based in Makurdi metropolis. A questionnaire was used to collect data from a sample of 250 SMEs in Makurdi metropolis which were selected through stratified random sampling method. Collected data were analyzed using descriptive and inferential statistics with the aid of Statistical Package for Social Sciences (SPSS). Correlation and multiple regression analysis were employed to analyse the data and test the hypotheses. The study revealed that innovativeness, creativity, business alertness and risk taking were significant in affecting performance of SMEs. The study concluded that entrepreneurial mindset or lack of it has a major effect on SMEs performance and if any economy is bended towards development and growth, it would have to embrace this concept. It recommended that all the policy makers and all stake holders should re-strategize and create forums that can promote entrepreneurial mindset among the existing and potential entrepreneurs.

Faire de la recherche avec des personnes classées déficientes intellectuelles
Authors: de Saint Martin Claire , Desjardins Michel 
Published: October 2018

Cet article vise à exposer comment deux types de « recherche avec », menés auprès de personnes déficientes intellectuelles dans deux pays différents, au Canada et en France, participent à la production de connaissances transcendant les particularités locales et nationales. L’examen critique de l’inclusion, qui préside à l’insertion sociale des personnes déficientes intellectuelles, a incité les deux chercheurs à mener avec ces personnes une « recherche avec », définie par la participation active des acteurs de terrain impliqués et la considération de leurs perceptions, indispensables à la production de connaissances scientifiques. La présentation des champs disciplinaire, théorique et méthodologique de chaque chercheur clarifie la place attribuée dans leurs recherches aux expériences et aux savoirs des personnes classées déficientes intellectuelles. Les résultats des deux recherches montrent une continuité dans l’itinéraire de ces personnes. La comparaison de ces deux « recherches avec » soulignent leurs similarités, leurs différences, leur complémentarité et leur potentielle bonification mutuelle.
Geriatric assessment teams in nursing homes: Do they work?
Authors: Cavalieri Thomas A. , Chopra Anita , Forman Lloyd J. , Gray-Miceli Deanna , Shreve Scott , Waxman Howard 
Published: October 2018

Abstract
Several studies have examined the effectiveness of geriatric assessment teams in outpatient and acute care settings. This project compared medical records of 69 consecutive nursing home patients randomly assigned on arrival to team (n=33) and nonteam (standard care, n=36) conditions. Quality-of-care indices and healthcare service utilization were compared over a 12-month postadmission period. Team patients had a significantly greater number of diagnoses and ancillary services combined with nonsignificant trends toward decreased mortality, fewer emergency department visits, and fewer drugs prescribed. The team approach improves quality of care. Additional clinical studies evaluating the effectiveness of geriatric assessment teams should be made in other nursing homes.
Myofascial manipulative release of carpal tunnel syndrome: Documentation with magnetic resonance imaging
Authors: Sucher Benjamin M. 
Published: October 2018

Abstract
Four patients with carpal tunnel syndrome, unresponsive to routine conservative care, underwent treatment with myofascial release manipulation and selfstretching. Magnetic resonance imaging analysis of the cross-sectional area of the carpal tunnel and electrodiagnosis were performed before and after treatment. The patients improved clinically. The nerve conduction studies showed concomitant reduction in distal latencies or increase in motor response amplitudes. Magnetic resonance imaging demonstrated that the anteroposterior and transverse dimensions of the carpal canal significantly increased after treatment. This study demonstrates that the carpal canal is a distensible structure with the potential to yield to a relatively simple, aggressive, nonsurgical treatment for carpal tunnel syndrome.
Hantavirus in the southwestern United States: Epidemiology of an emerging pathogen
Authors: Sands Lawrence , Kioski Clare , Komatsu Ken 
Published: October 2018

Abstract
In May of this year, an outbreak of sudden, unexplained, and highly fatal respiratory illness of unknown etiology was identified in the four-corners region of the southwestern United States. Within 3 weeks after the collaborative response launched by the state and local health agencies in the affected area, laboratory studies from the federal Centers for Disease Control and Prevention suggested that an acute infection with a previously unrecognized Hantavirus species was responsible for the reported cluster of cases. The hantavirus associated with this outbreak has since been isolated in tissue culture, and diagnostic test systems specific for the newly identified hantavirus have been developed. This article summarizes the history of the outbreak as experienced by investigators from the Arizona Department of Health Services and reviews the epidemiologic and clinical aspects of both the current epidemic and hantaviruses in general. The sudden occurrence of acute illnesses in the Southwest due to a previously unrecognized hantavirus reaffirms that the potential for the emergence of new infectious diseases exists at any place or time in the United States. The response to the outbreak also illustrates how community clinicians and federal, state, and local health agencies work together to promptly identify the emergence of new disease threats, rapidly determine new etiologic agents, and develop and swiftly implement appropriate disease prevention and control strategies.
Hantavirus pulmonary syndrome (HPS): Report of first case in Louisiana
Authors: Steier Kenneth J. , Clay Roy 
Published: October 2018

Abstract
Since May 1993, 26 people have died of a ''unique, previously unknown" viral illness that presents with flu-like symptoms and progresses rapidly to respiratory failure and death. Originally isolated in the four-corners region of the Southwest, the hantavirus responsible has now been isolated from patients in several other areas. In this article, we describe our experience with ''the most puzzling case so far," an infection by a "cousin" of the Southwest hantaviral strain in a Louisiana bridgeworker. This case is unique not only because of the slightly different makeup of the virus, but also because of the absence of deer mice, the suspected carrier of the hantavirus, in the Louisiana region.
Effects of adding sacral base leveling to osteopathic manipulative treatment of back pain: A pilot study
Authors: Hoffman Kent S. , Hoffman Lorrie L. 
Published: October 2018

Abstract
A selected group of patients with sacral base unleveling greater than 2 nun were studied to determine the effects of osteopathic manipulative treatment (OMT) and heel lifting on chronic low-back pain. The McGill-Melzack Pain Questionnaire administered by trained personnel was used to assess the patient's pain before and after treatments. Five patients with no experience with manual treatment were treated with nonsteroidal anti-inflammatory drugs (NSAIDs) and OMT for restrictions in spinal motion. Their improvement was statistically significant. Seven patients who had been treated previously with OMT and NSAIDs received heel lifts of graduated thickness until the sacral base was within 2 mm of being level. Attaining a "level" sacral base with heel lifts also provided a statistically significant relief from low-back pain.
Medicaid reform: An opportunity for the osteopathic medical profession
Authors: Ross-Lee Barbara , Weiser Michael A. 
Published: October 2018

Abstract
Established in 1965 to provide medical care for the impoverished, the Medicaid program has pitted state governments against the federal government, and made adversaries of the providers. The authors examine the legislative history of the program and the rapid growth of expenditures that have led states to cut benefits, tighten eligibility requirements, and slash payments to providers. The call for comprehensive healthcare reform and universal access put Medicaid at the forefront of proposed changes. The osteopathic medical profession, which already provides a quarter of the care in the program, has an opportunity to lead in innovation to promote program efficiencies, and to affirm the profession's commitment to serve vulnerable populations.
Endoscopic carpal tunnel release
Authors: Payne John C. , Bergman Ronald S. , Ettinger David J. 
Published: October 2018

Abstract
Conventional open carpal tunnel release effectively relieves symptoms, but involves pain and fairly long recovery time. A relatively new technique of endoscopic carpal tunnel release as described by Chow has been carried out on 20 hands in 16 patients. The endoscopic approach allows earlier return to normal activities with less postoperative pain than conventional or open release.
Recent advances in the detection of ovarian cancer: A review
Authors: Blend Michael J. , Ostrowski Gregory J. 
Published: October 2018

Abstract
Epithelial ovarian cancer is one of the more aggressive malignancies among American women today, and its incidence is increasing. The major obstacle in combatting ovarian cancer is the remarkable lack of symptoms in early-stage disease. Symptoms usually occur in advanced stages when tumor dissemination within the peritoneal cavity induces ascites with resultant increasing abdominal girth. Physicians have been unable to reach women who have early-stage ovarian cancer, a time when a high cure rate could be expected. However, during the past few years, significant developments in the areas of serum tumor markers, transvaginal ultrasonography with color flow Doppler analysis, immunodiagnostic techniques, and immunotherapy have been reported. These new modalities show promise for use in the early diagnosis and treatment of ovarian cancer. The authors review some of the new data and discuss patient outcomes when these new modalities are used.
Preparing the osteopathic academic health centers for healthcare reform
Authors: Ross-Lee Barbara , Weiser Michael A. 
Published: October 2018

Abstract
Healthcare reform proposals introduced in the House and Senate, put forward by foundations, professional associations and study groups, all call for medical schools to train more generalists. As these agents make recommendations for change, they are studying the osteopathic medical education model with fresh interest because of its success in maintaining more than 60% of its graduates in primary care practice. Most students of reform place the blame for producing too many specialists and subspecialists squarely on the academic health centers. The authors trace the development of academic health centers and compare and contrast the models developed in the osteopathic and allopathic medical settings. They enumerate the strengths in the osteopathic education model which have contributed to our favorable balance of generalists to specialists. However, they argue that specific changes in the osteopathic academic health center are essential if we are to retain leadership in generalist education under healthcare reform.
Lecithin-cholesterol acyltransferase deficiency: First report of case in a United States citizen
Authors: Neumann Michael J. , Whisiker-Lewis Stephanie 
Published: October 2018

Abstract
Lecithin-cholesterol acyltransferase is responsible for the formation of most cholesteryl esters in plasma. Absence of this enzyme can result in a rare syndrome that includes diffuse corneal opacities, normocytic normochromic anemia, proteinuria, renal failure, and premature arteriosclerosis. The deficiency can be inherited in an autosomal recessive manner, or it can be acquired through liver disease. Diagnosis requires a high index of suspicion and documentation of impairment of enzyme mass or activity (or both). This article includes a case report of the first United States citizen known to have lecithin-cholesterol acyltransferase deficiency. The authors review the literature related to this disease.
Predictability of sacral base levelness based on iliac crest measurements
Authors: Dott Gregory A. , Hart Curtis L. , McKay Claire 
Published: October 2018

Abstract
A level sacral base plane is necessary to allow normalization of complex lumbosacral mechanics. Palpatory examinations are often used to evaluate for leg length discrepancy and pelvic obliquity despite improved accuracy and consistency of radiographic techniques. Treatment based on palpatory examinations suppose a direct and consistent relationship between the pelvic bones (innominates) and the sacral base. 1b evaluate the relationship between iliac crest levelness and sacral base levelness, a radiographic postural survey in the upright, weight-bearing position was performed on 358 men and women thought to have pelvic obliquity. Of these subjects, 293 demonstrated unlevel iliac crest heights or sacral base ~3'16 inch (4.76 mm), with iliac crest heights accurately predicting sacral base position 62% of the time. At ~3/8 inch (9.53 mm), 68% of the cases were accurately predicted. When the criterion for unlevelness was increased to ~ 112 inch (12.70 mm), the predictive accuracy improved to 83%. Radiographic findings in this study demonstrate a significant difference between iliac crest heights and sacral base position. In cases of mild to moderate short leg syndromes, the iliac crest height is an unreliable predictor of the direction or degree of sacral base levelness.
Clinical implications of NSAID pharmacokinetics: Special populations, special considerations
Authors: Adelizzi Raymond A. 
Published: October 2018

Abstract
Nonsteroidal anti-inflammatory drugs (NSAIDs) are the centerpiece of pharmacologic therapy for most rheumatic disorders and related conditions, and as such are used in great numbers. These drugs are relatively safe and effective, but the pharmacokinetics of NSAIDs can be substantially altered in certain groups of patients, including the elderly and patients with renal and hepatic disease. In these patients, the risk of NSAID toxicity is increased. An understanding of NSAID pharmacokinetics in these groups can help physicians to adjust therapeutic regimens in order to limit the potentially serious complications of long-term NSAID therapy. The author discusses the age-related physiologic changes that may affect the various areas of drug pharmacokinetics and ways in which NSAIDs may interact with other drugs. Risk assessment and monitoring methods are also discussed.
