An analysis about the relationship between the cloud computing model and ITIL v3 2011

Cloud Computing is widely recognized as a recent computing paradigm of digital transformation in which scalable and elastic computational resources are delivered as a service through Internet technologies. Its characteristics made this business model increasingly adopted by organizations reaching business goals. Besides its benefits, some risks may impact organizations internally and, in the way they deliver their services to their clients. Therefore, it became important to understand the impacts of the Cloud model on the way companies organize their processes. The goal of this work is to investigate which are the main impacts arising from the Cloud Computing model currently impacting Information Technology Infrastructure Library framework processes. The methodology selected will be through semi-structured interviews with knowledgeable professionals to effectively collect practical information that, according to the Systematic Literature Review performed, could not be collected by the traditional literature. By analyzing the Systematic Literature Review results, several processes of this framework were affected, which may lead to a need for reframing it. Although the organization’s approach to this model must be enhanced and adapted to a new reality, the empirical insights collected from semi-structured interviews, suggest that the framework does not need to be reframed, and ITIL v3 2011 most impacted processes by the introduction of the Cloud-based model, are Change Management and Incident Management.A computação em nuvem é amplamente reconhecida como um paradigma de computação recente da transformação digital, no qual recursos computacionais escaláveis e elásticos são fornecidos como um serviço através de tecnologias na Internet. As suas características fizeram com que esse modelo de negócio fosse cada vez mais adotado por organizações que na prossecução dos seus objetivos de negócio. Além dos benefícios, também existem os riscos podem impactar as organizações internamente e na forma como entregam os seus serviços aos clientes. Portanto, tornou-se importante entender os impactos do modelo de Cloud na forma como as empresas organizam seus próprios processos e práticas. O objetivo deste trabalho é investigar quais são os principais impactos decorrentes do modelo de Cloud que impactam atualmente os processos da Information Technology Infrastructure Library. A metodologia selecionada será por meio de entrevistas semiestruturadas a profissionais capacitados para recolher informações decorrentes de experiências na prática que, de acordo com a Revisão Sistemática da Literatura realizada, não poderiam ser obtidas pela literatura tradicional. Ao analisar os resultados da Revisão Sistemática da Literatura, diversos processos desta framework foram afetados, o que pode levar à necessidade de reformulá-la. As considerações empíricas recolhidas nas entrevistas semiestruturadas, sugerem que a framework não necessita de ser reformulada e que os processos do ITIL v3 2011 mais impactados no modelo Cloud são o de Gestão de Incidentes e de Gestão da Mudança

Waist-to-height ratio is independently related to whole and central body fat, regardless of the waist circumference measurement protocol, in non-alcoholic fatty liver disease patients

This is the peer reviewed version of the following article: Pimenta N.M., Cortez-Pinto H., Melo X., Silva-Nunes J., Sardinha L.B. & Santa-Clara H. (2017) Waist-to-height ratio is independently related to whole and central body fat, regardless of the waist circumference measurement protocol, in non-alcoholic fatty liver disease patients. J Hum Nutr Diet. 30, 185–192, which has been published in final form atdoi: 10.1111/jhn.12410. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Use of Self-Archived Versions.Background: Waist-to-height ratio (WHtR) has been reported as a prefer-able risk related body fat (BF) marker, although no standardised waistcircumference measurement protocol (WCmp) has been proposed. Thepresent study aimed to investigate whether the use of a different WCmpaffects the strength of relationship between WHtR and both whole andcentral BF in non-alcoholic fatty liver disease (NAFLD) patients.Methods: BF was assessed with dual energy X-ray absorptiometry (DXA) in28 NAFLD patients [19 males, mean (SD) 51 (13) years and nine females,47 (13) years]. All subjects also underwent anthropometric evaluationincluding height and waist circumference (WC) measurement using fourdifferent WCmp (WC1, minimal waist; WC2, iliac crest; WC3, mid-distancebetween iliac crest and lowest rib; WC4, at the umbilicus) and WHtR wascalculated using each WC measurements (WHtR1, WHtR2, WHtR3 andWHtR4, respectively). Partial correlations were conducted to assess the rela-tion of WHtR and DXA assessed BF.Results: All WHtR were particularly correlated with central BF, includingabdominal BF (r = 0.80, r = 0.84, r = 0.84 and r = 0.78, respectively, forWHtR1, WHtR2, WHtR3 and WHtR4) and central abdominal BF (r = 0.72,r = 0.77, r = 0.76 and r = 0.71, respectively, for WHtR1, WHtR2, WHtR3and WHtR4), after controlling for age, sex and body mass index. There wereno differences between the correlation coefficients obtained between allstudied WHtR and each whole and central BF variable.Conclusions: Waist-to-height ratio was found a suitable BF marker in thepresent sample of NAFLD patients and the strength of the relationshipbetween WHtR and both whole and central BF was not altered by usingdifferent WCmp in the present sample of NAFLD patients.FUNDING SOURCES The first author of this paper was supported by a research grant (PhD scholarship) from the Foundation for Science and Technology (FCT), Ministry of Education and Science of Portugal (grant: SFRH/ BD/ 70515/ 2010).

Waist circumference in Liver Disease

Background Central fat accumulation is important in Non-alcoholic Fatty Liver Disease (NAFLD) etiology. It is unknown weather any commonly used waist circumference (WC) measurement protocol (mp), as whole and central fat accumulation marker, is preferable for patients with NAFLD. The present study sought to find a preferable WC mp to be used in patients with NAFLD, based on three-fold criterion. Material and methods Body fat (BF) was assessed through Dual Energy X-ray Absorptiometry (DXA) in 28 patients with NAFLD (19 males, 51 + 13 yrs, and 9 females, 47 + 13 yrs). WC was measured using four different WC mp (WC1-narrowest torso, WC2- just above iliac crest, WC3- mid-distance between iliac crest and last rib and WC4- at the umbilicus). Results All WC measurements were highly correlated particularly with central BF depots, including trunk BF (r=0.78; r=0.82; r=0.82; r=0.84; respectively for WC1, WC2, WC3 and WC4) abdominal BF (r=0.78; r=0.78; r=0.80; r=0.72; respectively for WC1, WC2, WC3 and WC4) and central abdominal BF (r=0.76; r=0.77; r=0.78; r=0.68; respectively for WC1, WC2, WC3 and WC4), controlling for age, sex and body mass index. There were no differences between the correlation coefficients obtained between all studied WC measurements and each whole and central analyzed BF variable. Conclusion All studied WC mp seem suitable for use in patients with NAFLD, particularly as central BF clinical assessment tool, though not interchangeably. Hence biological and precision criteria alone did not sanction the superiority of any WC mp. Practical criteria may endorse WC measured at the iliac crest.info:eu-repo/semantics/publishedVersio

Waist-to-Hip Ratio is Related to Body Fat Content and Distribution Regardless of the Waist Circumference Measurement Protocol, in Non-Alcoholic Fatty Liver Disease Patients

Central accumulation and distribution of body fat (BF) is an important cardiometabolic risk factor. Waist-to-hip ratio (WHR), commonly elevated in non-alcoholic fatty liver disease (NAFLD) patients, has been endorsed as a risk related marker of central BF content and distribution, but no standardized waist circumference measurement protocol (WCmp) has been proposed. We aimed to investigate whether using different WCmp affects the strength of association between WHR and BF content and distribution in NAFLD patients. BF was assessed with Dual Energy X-ray Absorptiometry (DXA) in 28 NAFLD patients (19 males, 51 ± 13 yrs, and 9 females, 47 ± 13 yrs). Waist circumference (WC) was measured using four different WCmp (WC1: minimal waist; WC2: iliac crest; WC3: mid-distance between iliac crest and lowest rib; WC4: at the umbilicus) and WHR was calculated accordingly (WHR1, WHR2, WHR3 and WHR4, respectively). High WHR was found in up to 84.6% of subjects, depending on the WHR considered. With the exception of WHR1, all WHR correlated well with abdominal BF (r=0.47 for WHR1; r=0.59 for WHR2 and WHR3; r=0.58 for WHR4) and BF distribution (r=0.45 for WHR1; r=0.56 for WHR2 and WHR3; r=0.51 for WHR4), controlling for age, sex and body mass index (BMI). WHR2 and WHR3 diagnosed exactly the same prevalence of high WHR (76.9%). The present study confirms the strong relation between WHR and central BF, regardless of WCmp used, in NAFLD patients. WHR2 and WHR3 seemed preferable for use in clinical practice, interchangeably, for the diagnosis of high WHR in NAFLD patients.co-financed by national funds through the Programa Operacional do Alentejo (ALENT-07-0262-FEDER-001883)info:eu-repo/semantics/publishedVersio

Data pre-processing for database marketing

To increase effectiveness in their marketing and Customer Relationship Manager activities, many organizations are adopting strategies of Database Marketing (DBM). Nowadays, DBM faces new challenges in business knowledge since current strategies are mainly approached by classical statistical inference, which may fail when complex, multi-dimensional and incomplete data is available. An alternative is to use Knowledge Discovery from Databases (KDD), which aims at automatic extraction of useful patterns by using Data Mining (DM) techniques. When applied to DBM, the identified patterns can be used for the efficient characterization of the customers. This paper focus several problems that arose in the data pre-processing step (e.g. data cleaning), which is necessary for the success of the DM approach to a DBM project
