Combination of product quality management and exports: The case of Colombian fruits companies

Quality management provides to companies a framework to improve quality in overall systems, reduction of costs, reallocation of resources efficiently, correct planning of strategies, prevent or correct errors in the right time and increase the performance of companies. In this text, we discuss the different theories in this field, their obligatory or non-obligatory compliance, the importance of quality management for exporting companies and a case study of a Colombian firm that its main objective is to manage quality. In conclusion, we find out that there is different types of quality management systems such as Juran’s trilogy, Deming 14 points, Six sigma, HACCP, and so on; also that companies have to manage suppliers and that quality has a positive influence on exports volume; in the case of Colombian small and medium enterprises, it can be mentioned that the majority has implemented tools regarding quality management but is not enough.

A hypothesis for explaining single outbreaks (like the Black Death in European cities) of vector-borne infections

We propose a mechanism by which single outbreaks of vector-borne infections can happen even when the value of the basic reproduction number, R(o), of the infection is below one. With this hypothesis we have shown that dynamical models simulations demonstrate that the arrival of a relatively small (with respect to the host population) number of infected vectors can trigger a short-lived epidemic but with a huge number of cases. These episodes are characterized by a sudden outbreak in a previously virgin area that last from weeks to a few months, and then disappear without leaving vestiges. The hypothesis proposed in this paper to explain those single outbreaks of vector-borne infections, even when total basic reproduction number, Ro, is less than one (which explain the fact that those infections fail to establish themselves at endemic levels), is that the vector-to-host component of Ro is greater than one and that a sufficient amount of infected vectors are imported to the vulnerable area, triggering the outbreak. We tested the hypothesis by performing numerical simulations that reproduce the observed outbreaks of chikungunya in Italy in 2007 and the plague in Florence in 1348. The theory proposed provides an explanation for isolated outbreaks of vector-borne infections, ways to calculate the size of those outbreaks from the number of infected vectors arriving in the affected areas. Given the ever-increasing worldwide transportation network, providing a high degree of mobility from endemic to virgin areas, the proposed mechanism may have important implications for public health planning.

Avaliação do impacto da marcha com canadianas no dispêndio energético: análise comparativa entre jovens e idosos

Introdução: As canadianas são utilizadas em múltiplos quadros clínicos em que existe compromisso da marcha. No entanto, é fulcral considerar as diferentes exigências metabólicas associadas a cada auxiliar e tipo de marcha. Objetivo: Avaliar o dispêndio energético (DE) na marcha normal (MN), com uma canadiana e com duas canadianas a 3 pontos e a 3 pontos modificada em jovens e idosos. Metodologia: Estudo analítico transversal, composto por 21 indivíduos. As variáveis analisadas foram o volume de oxigénio inspirado (VO2), volume de dióxido de carbono expirado (VCO2) e quociente respiratório (QR), obtidas através do sistema portátil (Cosmed K4b2, Cosmed, Roma, Itália). Resultados: Os participantes tinham idades entre 18 e 75 anos (11 jovens e 10 idosos). Os idosos apresentaram valores significativamente mais elevados que os jovens no DE na marcha com uma canadiana a 3 pontos (p=0,009) e com duas canadianas a 3 pontos (p=0,008), enquanto nas restantes marchas não houve diferenças estatisticamente significativas (p>0,05). A MN e a marcha com duas canadianas a 3 pontos foram os tipos de marcha com maior DE nos jovens, e nos idosos. Nos jovens, a MN apresentou 19% a 45% maior DE do que as restantes marchas, enquanto nos idosos verificou-se que todas as marchas (à exceção de uma canadiana a 3 pontos modificada) apresentaram um maior DE (entre 7 e 16%) comparativamente à MN. Conclusão: Os idosos apresentaram valores significativamente mais elevados de DE que os jovens nas marchas uma e duas canadianas a 3 pontos. Na MN e na marcha uma canadiana a 3 pontos modificada existe uma tendência para os jovens apresentarem valores de DE superior aos idosos. A medição do DE fornece uma indicação precisa da eficiência da marcha, sendo útil como suporte para a decisão clínica e para uma adequada reabilitação.

A influência da marcha com tripé nos parâmetros metabólicos em jovens e idosos

Introdução: Os parâmetros metabólicos durante a marcha normal e a sua regulação são importantes devido ao metabolismo oxidativo ser o principal meio através do qual o organismo humano gera energia para realizar as atividades do quotidiano. Nem sempre a marcha é realizada de forma independente e necessita do apoio de auxiliares de marcha, como o tripé, que tem por função ampliar a base de sustentação e melhorar o equilíbrio. Objetivo: Analisar a influência de utilização de um tripé na marcha, na despesa energética em jovens e idosos saudáveis Métodos: Realizou-se um estudo observacional transversal numa amostra de 21 voluntários, com idade entre 18 a 25 anos e mais ou igual a 60 anos. Realizaram-se as avaliações com o Cosmed K4b2 (Cosmed, Rome, Italy), sendo através do mesmo que os dados foram recolhidos. Foi utilizado o teste de Friedman, com P <0,05. Resultados: Os resultados obtidos para o gasto energético nos jovens foram inferiores aos valores obtidos pelos idosos. Relativamente ao metabolismo energético o substrato energético utilizado pelos jovens foi o proteico e o lipídico pelos idosos. Entre sexos foram os homens quem tiveram um maior gasto energético. Conclusão: O uso do tripé durante a marcha não influencia o gasto energético em adultos jovens e/ou idosos saudáveis.

Small Bowel Bacterial Overgrowth is found in 71% of IBS patients and associated symptoms respond wel to Rifaximin in a phase IV trial

Background: The prevalence of small intestinal bowel bacterial overgrowth (SIBO) in patients with irritable bowel syndrome (IBS) ranges from 43% to 78% as determined by the lactulose hydrogen breath (LHBT) test. Although rifaximine, a non-absorbable antibiotic, has been able to decrease global IBS symptoms as well as bloating in placebo-controlled randomized trials, these results were not repeated in phase IV studies in daily clinical practice. Aim: To assess the prevalence of SIBO in an IBS cohort and to evaluate the treatment response in the IBS cohort affected by SIBO. Methods: Enrolled patients were diagnosed with IBS using the following criteria: fulfillment of the Rome III criteria, absence of alarm symptoms (anemia, weight loss, nocturnal symptoms etc), normal fecal calproectin, normal endoscopic workup including histology. Celiac disease was excluded by serology and/or duodenal biopsy. All patients underwent lactulose hydrogen breath testing (LHBT) for SIBO diagnosis. Patients with SIBO were treated with rifaximine tablets (400mg twice daily for 14 days). Both before and at week 6 after rifaximin treatment, patients completed a questionnaire, where the following criteria were assessed individually using 11-point Likert scales: the bloating, flatulence, abdominal pain, diarrhea, and overall well-being. Results: Hundred-fifty IBS patients were enrolled (76% female, mean age 44 ± 16 years), of whom 106 (71%) were diagnosed with SIBO and consequently treated with rifaximine. Rifaximine treatment significantly reduced the following symptoms as assessed by the symptom questionnaire: bloating (5.5 ± 2.6 before vs. 3.6 ± 2.7 after treatment, p <0.001), flatulence (5 ± 2.7 vs. 4 ± 2.7, p = 0.015), diarrhea (2.9 ± 2.4 vs. 2 ± 2.4, p = 0.005), abdominal pain (4.8 ± 2.7 vs. 3.3 ± 2.5, p <0.001) and resulted in improved overall well-being (3.9 ± 2.4 vs. 2.7 ± 2.3, p <0.001). Thirteen of the 106 treated patients were lost to follow-up (12%). The LHBT was repeated 2-4 weeks after rifaximine treatment in 65/93 (70%) patients. Eradication of SIBO was documented in 85% of all patients (55/65), whereas 15% of patients (10/65) tested positive for SIBO as determined by the LHBT testing. Conclusions: The results of our phase IV trial indicate that a high proportion of IBS patients tested positive for SIBO. IBS symptoms (bloating, flatulence, diarrhea, pain, overall well-being) were significantly diminished following a 2-week treatment with rifaximine. These results support the previous findings of randomized controlled trials that the presence of SIBO is associated with symptom generation in IBS patients and that reduction and/or elimination of SIBO may help to alleviate IBSassociated symptoms.

Not the right job but a secure one : over-education and temporary employment in France, Italy and Spain

Resorting to four waves of the European Community Household Panel, this research explores the association between temporary employment and the likelihood of being over-educated. Such an association has been largely ignored by the literature explaining over-education, more inclined to attribute such a mismatch to the system of education. Selecting three similarly standarised and stratified systems of education (France, Italy and Spain) and controlling for many other variables likely to affect over-education, like gender, age, tenure, job change, firm size or sector, the paper demonstrates that such an association between temporary employment and over-education exists. Being a stepping stone towards a more stable and adjusted position in the labour market, holding a temporary employment may be associated to a higher likelihood of being over-educated. Such an association is more likely in Italy and France. Yet, the opposite sign prevails where permanent employment becomes such a valuable asset as to make individuals trade human capital by employment security. This is the case of Spain.

Finding a suitable job: the effect of the institutional context on self-perceived over-education

The current research compares the perception of over-education in four different European countries, resorting to European Household Panel Data. The results confirm that the type of educational system accounts for some of the cross-national differences in self-perceived over-education. In qualificational spaces, like Denmark, where vocational training receives more importance, self-perceived over-education is not associated as much with educational attainment as in the so-called’ organisational spaces’, like Spain, France and Italy. Yet, the results confirm that, controlling for the system of education, the traits and regulation of the labour market also have an effect on over-education. Thus, in Spain, where temporary employment has soared in recent decades, this type of contract is clearly associated with the perception of over-education, to a much higher extent than in Italy or France. Temporary contracts in Spain may not work as a steppig stone for attaining a job suitable to the training received by the individual, as they may in the case of France or Italy. In sum, not only institutions offering skills and human capital, but labour market regulation as well, have a clear impact on the incidence of over-education.

A Miocene mud volcano and its plumbing system: A chaotic complex revisited (Monferrato, NW Italy)

Chaotic deposits are frequently reported in the geological literature and are commonly interpreted as olistostromes or tectonic melanges. A chaotic complex in the Cenozoic succession of Monferrato (NW Italy) consists of interbedded mud breccia and burrowed silty clays that are pierced by sheared mud breccias and embed carbonate-cemented blocks. These may be represented by microcrystalline limestones or strongly cemented matrix-supported breccias locally containing remains of chemosymbiotic organisms (lucinid bivalves). Moreover, cylindrical concretions, up to 15 cm in diameter and 1 m long, occur in the chaotic complex and crosscut bedding planes at high angles. The cement of all these lithified portions is mainly dolomite characterized by low delta(13)C values (from -10.3 to -23parts per thousand PDB) and delta(18)O values up to + 7parts per thousand PDB. The delta(13)C values testify to precipitation of carbonates induced by microbial oxidation of methane, whereas the markedly positive delta(18)C signature, ubiquitous in the cylindrical concretions, is the evidence for the presence and destabilization of gas hydrates. The studied section provides a well-exposed example of the geological record of the birth, life, and death of a mud volcano. Unsheared, soft mud breccias represent mud flows along the flanks of the volcano, whereas sheared mud breccias are the result of the injection of unconsolidated overpressured fine-grained sediments, both taking place during ``eruptive'' phases. They were followed by more quiet stages of hemipelagic sedimentation, burrowing, and CH4 seeping. The cylindrical concretions represent the first described ancient example of the chimneys observed in present-day mud-volcano settings. They are the remnants of a cold-seep plumbing network that crosscut the mud volcano edifice. The chimneys were the pathway for the expulsion toward the sea floor of gas- and sediment-charged fluids likely originated from destabilization of methane gas hydrates. The association of mud breccias and methane-derived carbonates may not be due to mass gravity flows but can be primary and, therefore, is a diagnostic criterion for recognizing chaotic deposits due to mud volcano activity in the geological record.

Patients' right to information: a review of the regulatory and ethical framework

[eng] Aim: The paper examines the current situation of recognition of patients' right to information in international standards and in the national laws of Belgium, France, Italy, Spain (and Catalonia), Switzerland and the United Kingdom.Methodology: International standards, laws and codes of ethics of physicians and librarians that are currently in force were identified and analyzed with regard to patients' right to information and the ownership of this right. The related subjects of access to clinical history, advance directives and informed consent were not taken into account.Results: All the standards, laws and codes analyzed deal with guaranteeing access to information. The codes of ethics of both physicians and librarians establish the duty to inform.Conclusions: Librarians must collaborate with physicians in the process of informing patients.

Prevalence of frailty in middle-aged and older community-dwelling Europeans living in 10 countries.

BACKGROUND: Frailty is an indicator of health status in old age. Its frequency has been described mainly for North America; comparable data from other countries are lacking. Here we report on the prevalence of frailty in 10 European countries included in a population-based survey. METHODS: Cross-sectional analysis of 18,227 randomly selected community-dwelling individuals 50 years of age and older, enrolled in the Survey of Health, Aging and Retirement in Europe (SHARE) in 2004. Complete data for assessing a frailty phenotype (exhaustion, shrinking, weakness, slowness, and low physical activity) were available for 16,584 participants. Prevalences of frailty and prefrailty were estimated for individuals 50-64 years and 65 years of age and older from each country. The latter group was analyzed further after excluding disabled individuals. We estimated country effects in this subset using multivariate logistic regression models, controlling first for age, gender, and then demographics and education. RESULTS: The proportion of frailty (three to five criteria) or prefrailty (one to two criteria) was higher in southern than in northern Europe. International differences in the prevalences of frailty and prefrailty for 65 years and older group persisted after excluding the disabled. Demographic characteristics did not account for international differences; however, education was associated with frailty. Controlling for education, age and gender diminished the effects of residing in Italy and Spain. CONCLUSIONS: A higher prevalence of frailty in southern countries is consistent with previous findings of a north-south gradient for other health indicators in SHARE. Our data suggest that socioeconomic factors like education contribute to these differences in frailty and prefrailty.

The Arcuated Lintel and the "Serlian Motif". Imperial Identity, Architectural and Symbolic Interactions in Ancient Rome

Essay on the origin, use and development of the arcuated lintel in ancient Rome and the configuration of the so– called ‘Serlian motif’. These architectural elements will be related to the architecture of prestige on its technical, functional, visual and symbolic sphere. Its depictions, in addition to buildings, can offer a rich repertory of images that speak about the relations between visual culture, religion and power. Furthermore, the analyzed motifs will become important elements of the Western cultural legacy for centuries. The analysis of these events will contribute to the comprehension of the role played by some resources of ancient Rome architecture of prestige and its success

Prototype of a web-based participative decision support platform in natural hazards and risk management

This paper presents the current state and development of a prototype web-GIS (Geographic Information System) decision support platform intended for application in natural hazards and risk management, mainly for floods and landslides. This web platform uses open-source geospatial software and technologies, particularly the Boundless (formerly OpenGeo) framework and its client side software development kit (SDK). The main purpose of the platform is to assist the experts and stakeholders in the decision-making process for evaluation and selection of different risk management strategies through an interactive participation approach, integrating web-GIS interface with decision support tool based on a compromise programming approach. The access rights and functionality of the platform are varied depending on the roles and responsibilities of stakeholders in managing the risk. The application of the prototype platform is demonstrated based on an example case study site: Malborghetto Valbruna municipality of North-Eastern Italy where flash floods and landslides are frequent with major events having occurred in 2003. The preliminary feedback collected from the stakeholders in the region is discussed to understand the perspectives of stakeholders on the proposed prototype platform.

Le statut de Rome de la cour pénale internationale et le droit interne d’un pays en situation de conflit armé : le cas de la Colombie

L'incorporation du Statut de Rome de la Cour pénale internationale dans l’ordre juridique d'un État partie représente pour celui-ci un énorme engagement envers la justice, la protection et la garantie des droits fondamentaux de la personne humaine. La situation est particulièrement préoccupante dans le cas de la Colombie où la violation de ces droits fondamentaux a historiquement été notoire au cours du conflit armé interne qui sévit encore dans le pays aujourd’hui. Du fait de la ratification du Statut de Rome par l'État colombien, ce pays a le devoir de privilégier la recherche de la vérité, de la justice, de la réparation intégrale et les garanties de non-répétition pour les victimes du conflit armé. Ce traité international vise à empêcher la mise en place de règles consacrant l'impunité et empêchant de connaître la vérité de faits, comme ce qui a longtemps été le cas dans ce pays et qui a entraîné la prolongation du conflit pendant tant d'années. L'adoption du Statut de Rome par l'État colombien a produit différents effets juridiques dans le droit interne colombien. Certains de ces effets peuvent être observés dans les lois adoptées par le Congrès de la République ainsi que dans les arrêts de la Cour constitutionnelle et de la Cour suprême de justice où s'expriment les obligations internationales de l'État, rattachées au respect du système universel des droits de l'homme. Ce mémoire vise ainsi entre autres à exposer de quelle manière les dispositions sur les amnisties et la Loi Justice et paix rendent inefficace la mise en œuvre législative du Statut de Rome en Colombie.
