Diaphragmatic rupture with right colon and small intestine herniation after blunt trauma: a case report
Mirko Muroni, Giuseppe Provenza, Stefano Conte, Andrea Sagnotta, Niccolò Petrucciani, Ivan Gentili, Tatiana Di Cesare, Andrea Kazemi, Luigi Masoni, Vincenzo Ziparo
Journal of Medical Case Reports , 2010, DOI: 10.1186/1752-1947-4-289
Abstract: We report a case of a 59-year-old Italian man hospitalized for abdominal pain and vomiting. His medical history included a blunt trauma seven years previously. A chest X-ray showed right diaphragm elevation, and computed tomography revealed that the greater omentum, a portion of the colon and the small intestine had been transposed in the hemithorax through a diaphragm rupture. The patient underwent laparotomy, at which time the colon and small intestine were reduced back into the abdomen and the diaphragm was repaired.This was a unusual case of traumatic right-sided diaphragmatic hernia. Diaphragmatic ruptures may be revealed many years after the initial trauma. The suspicion of diaphragmatic rupture in a patient with multiple traumas contributes to early diagnosis. Surgical repair remains the only curative treatment for diaphragmatic hernias. Prosthetic patches may be a good solution when the diaphragmatic defect is severe and too large for primary closure, whereas primary repair remains the gold standard for the closure of small to moderate sized diaphragmatic defects.Traumatic rupture of the diaphragm is an uncommon condition. It occurs in 0.8 to 5% of patients admitted to hospital with thoracoabdominal trauma. The etiologic factors are blunt trauma (for example, in motor vehicle accidents) and penetrating trauma [1]. The organs most commonly involved in right-sided diaphragmatic hernias are the colon, omentum, small intestines and liver.Chest radiography and computerized tomography is the most effective method for diagnosis of traumatic diaphragmatic rupture [2]. Treatment is surgical, with reduction of the viscera and simple repair of the diaphragm with non-absorbable suture.A 59-year-old Italian man presented with abdominal pain localized in the right upper quadrant, constipation and vomiting for longer than one week. The patient had inconstant symptoms including shortness of breath and dyspnea. His medical history included right-sided rib fractures in a moto
Integration of Highly Qualified Sub-Saharan Immigrants in Prague  [PDF]
Andrea Gerstnerová
Sociology Mind (SM) , 2011, DOI: 10.4236/sm.2011.12006
Abstract: Successful integration of immigrants into the host society demands a creation of specific conditions that would facilitate immigrants their adaptation to a new sociocultural, economic and political environment. Therefore, the process of integration itself is not only a task for immigrants, but also for a majority. One of the key factors for a creation of truly cohesive society is the support of positive aspects of mutual inter-cultural relations. This could be reinforced by implementation of “adequate” integration programs adapted to the local context as well as sensible use of mass media. If the host society does not dispose of effective instruments to integrate its “own citizens”, it is generally difficult to create strategies for insertion of immigrants of different cultural backgrounds (such as Sub-Saharan Africans). Basic features of the integration process of Sub-Saharan Africans and political reactions of the major society were identified in Prague, Paris, London and Liege.
Undesired Excess Capacity and Equilibrium in an Advanced Market Economy  [PDF]
Andrea Pannone
Modern Economy (ME) , 2013, DOI: 10.4236/me.2013.411079
Abstract:

In this paper I attempt to give theoretical foundation to the concept of undesired excess capacity that I define as an unwilling, persistent mismatch between productive capacity and final demand. Undesired excess capacity has traditional room only in oligopolistic framework, like in Keynesian and Post-Keynesian models. Otherwise I show the possibility of its existence (and persistence) also with reference to a perfectly competitive economy where firms use massively information and communication technologies (ICT). In this stylized economy, undesired excess capacity is associated with “ex-post sunk costs, in terms of mismatch between total revenues and production costs. My approach, which draws a production theory alternative to the neoclassical one, makes it possible to account for these costs and connect them to the role of money, under the form of credit, in the continuation of the economic process. Moreover, in the conclusion of this paper, I show how the notion of equilibrium that emerges from the analysis could be useful to address the issue of dynamics.

Lerner Index, Productive Efficiency and Homotheticity  [PDF]
Andrea Mantovi
Theoretical Economics Letters (TEL) , 2015, DOI: 10.4236/tel.2015.53042
Abstract: Chambers et al. (2014) set forth a decomposition of the Lerner index, which results in a function on the full space \"\"?of input and output prices and quantities, such that the effect of the Farrell output measure of technical efficiency is explicit. In close correspondence, a decomposition of the Lerner index is established in which allocative efficiency (in both standard and reversed form, as defined by Bogetoft et al., 2006) complements the effect of input technical efficiency, with the reversed decomposition bound to the hypothesis of homotheticity. The resulting functions on \"\"are conjectured to define pregnant perspectives on the benchmark relevance of homothetic models, and their generalizations to multiple output.
Spherical Casimir Effect for a Massive Scalar Field on the Three Dimensional Ball  [PDF]
Andrea Erdas
Journal of Modern Physics (JMP) , 2015, DOI: 10.4236/jmp.2015.68115
Abstract: The zeta function regularization technique is used to study the Casimir effect for a scalar field of mass m satisfying Dirichlet boundary conditions on a spherical surface of radius a. In the case of large scalar mass, \"\", simple analytic expressions are obtained for the zeta function and Casimir energy of the scalar field when it is confined inside the spherical surface, and when it is confined outside the spherical surface. In both cases the Casimir energy is exact up to order \"\"and contains the expected divergencies, which can be eliminated using the well established renormalization procedure for the spherical Casimir effect. The case of a scalar field present in both the interior and exterior region is also examined and, for \"\", the zeta function, the Casimir energy, and the Casimir force are obtained. The obtained Casimir energy and force are exact up to order \"\"and \"\"respectively. In this scenario both energy and force are finite and do not need to be renormalized, and the force is found to produce an outward pressure on the spherical surface.
The dichotomy that faces nursing tutorial staff  [PDF]
Andrea M. Corbett
Open Journal of Nursing (OJN) , 2011, DOI: 10.4236/ojn.2011.11002
Abstract: There is a requirement for tutorial staff teaching on a degree programme to be engaged in research activity on a continuing basis. This is often in conflict with the demands that tutors in the Bachelor of Nursing programme are required to have academic ability and clinical skills whilst at the same time, engage in meaningful research activity. This does not occur. A study of the literature finds a commonality of this dichotomy throughout the world. A question is raised as to the impact of the increasing age of the nursing workforce; does this have an impact on the develop-ment of a research culture? It is suggested that the joint project approach adopted by the WITT (Western Institute of Technology at Taranaki) School of Nursing will assist in overcoming some of the identi-fied issues and begin the development of a research culture within the School that will be ongoing.
Financial Innovation, Macroeconomic Volatility and the Great Moderation  [PDF]
Lorenzo Bencivelli, Andrea Zaghini
Modern Economy (ME) , 2012, DOI: 10.4236/me.2012.35071
Abstract: In the paper we propose an assessment of the role of financial innovation in shaping US macroeconomic dynamics. We extend an existing model by Christiano, Eichenbaum and Evans which studied the transmission of monetary policy im- pulses to business and corporate sector financing variables just before the Great Moderation period. By investigating the properties of the model over a longer time span we show that in the later period a change in the monetary policy trans- mission mechanism is likely to have occurred. In particular, we argue that the role of financial innovation has signify- cantly altered the transmission of shocks.
Disclosure of Disability by University Students: Development of a Study Protocol  [PDF]
Andrea De Cesarei
Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.28012
Abstract: Within the life course of a person with disability, higher education represents an important step, and the disclosure of a disability is one of the first and most important choices that the person with disability has to take. Based on a review of the literature, it is described how a research protocol for investigating the effects of Self Efficacy and Metacognition on the Disclosure of Disability by university students is developed. These data would provide information concerning the predictive effects of the metacognitive skills, social support and self-efficacy on the attitudes towards the disclosure of a disability.
The Serological Diagnosis of Canine Leishmaniasis: Commercial ELISA or in House IFAT?  [PDF]
Pasquale Santoro, Andrea Vellusi
Open Journal of Veterinary Medicine (OJVM) , 2015, DOI: 10.4236/ojvm.2015.52005
Abstract: The levels of anti-Leishmania infantum antibodies are relevant with the diagnosis and the followup of infected dogs. Both ELISA (Enzyme-Linked Immunosorbent Assay) and IFAT (Indirect Immuno-Fluorescent Antibody Test) may be employed to estimate the antibody levels in dogs, but at present, the correlation between ELISA absorbance and IFAT titer has not been investigated. In this paper, we compared the optical densities obtained with a commercial ELISA, Leiscan?(Laboratorios Dr. Esteve S.A.), versus the titers obtained by in house IFAT. We measured ELISA absorbance of: 44 IFAT negative samples coming from an endemic area; 10 negative samples coming from a non endemic area; 29 samples with an IFAT titer between 1/40 and 1/80; 10 samples with an IFAT titer of 1/160; 9 samples with an IFAT titer of 1/320; 10 samples with an IFAT titer of 1/640; 10 samples with an IFAT titer ≥ of 1/1280. Results show that: a) there is a poor correlation between IFAT titer and ELISA absorbance; b) Leiscan? is not able to distinguish between IFAT negative samples and IFAT titers up to 1:160; c) IFAT negative samples from an endemic or non endemic area show different ELISA absorbance; d) the performance of the kit may be improved by the use of a more appropriate cut-off.
Market Regulation, Labor Policies and the Wage-Productivity Gap  [PDF]
Riccardo Tilli, Andrea Rollin
Modern Economy (ME) , 2017, DOI: 10.4236/me.2017.83029
Abstract: This paper proposes an empirical analysis about the influence of some institutional factors (taxation, active and passive labor market policies, labor and goods market regulation and unions’ participation) on the component of the wage growth not explained by the productivity growth (WP gap, thereafter). We consider a 14 OECD countries Panel Data over the period 1983-2003, using four different estimations: fixed effects vector decomposition (FEVD), fixed effects (FE), random effects (RE) and feasible general least square (FGLS). Results for all estimations show that the WP gap is affected by tax wedge, active labor market policies, employment protection for temporary workers and union density, while product market regulation and passive labor market policies do not play a significant role.
