Italian validation of the Wagnild and Young Resilience Scale: a perspective to rheumatic diseases.

OBJECTIVES
Studying the characteristics of resilience may help to explain how, in the face of a chronic disease, people are able to cope in productive and effective ways. The Wagnild and Young Resilience Scale (RS) is an appropriate instrument to study resilience and has already been translated from the original English version into several languages. The aim of this study was to validate the Italian version of the RS, a 25-item scale ranging from 25 to 175 where higher scores indicate stronger resilience.


METHODS
The Minimal Translation Criteria were followed to translate the scale which was then filled out by 1090 students to assess the reliability, stability, internal consistency and concurrent validity.


RESULTS
Time stability was assessed in a sample of 117 students (M age=20.18 yr, SD 1.25) by test-retest correlation (r=0.78). RS reliability was evaluated in a second sample of 973 students (M age=16.95 yr, SD 1.50) with RS mean of 126.6 (SD 17.4). Concurrent validity was assessed by correlation with General Health Questionnaire (r=-0.51), Ego-Resilience Scale (r=0.63) and Beck Depression Inventory (r=-0.45). Internal consistency was evaluated by Cronbach alpha (α=0.84). Principal component analysis was performed on 24 out of the 25 items and resulted in six components.


CONCLUSIONS
Our data indicated that the 24-item Italian version of the RS scale can be considered a useful instrument to measure resilience and can be used by healthcare staff to help patients cope effectively with stressful situations such as rheumatic and other chronic diseases.
Fourth Workshop and Tutorial on Practical Use of Coloured Petri Nets and the CPN Tools

Petri Nets are a powerful technique for modelling, analysing, and validating all kinds of systems. In order to exploit the full power of Petri nets, different versions of Petri nets and tools need to be used, and, sometimes, we need to combine them with other techniques. This makes it necessary to model the same system in different Petri net formalisms or other notations over and over again. Moreover, systems will often be constructed from standard components so that the modeller would like to build his system from these components. This way, even users with no experience in Petri nets can model systems. In order to help this group of users, the analysis results obtained by Petri net tools or other formal methods must be presented and visualized independently from Petri nets. Component Tools is a platform designed for this purpose. Along with a 3D-visualisation of the behaviour of the system (PNVis), non-experts can build Petri net models and see their model running in (virtual) reality. The tutorial will cover the concepts of ComponentTools as well as the concepts and modelling philosophy of the 3D-visualisation. Moreover, the tutorial will discuss the underlying software technology which makes it easy to implement this kind of tools. In addition to the existing concepts the tutorial will give an overview of ideas for future work and challenging research projects -with the potential for many PhD theses. References E.

Sonar image segmentation using the angular dependence of backscattering distributions

In high resolution sonar imaging, the K-distribution has shown interesting properties for describing the statistics of backscattered intensity. This distribution is a function of two parameters. The first one is the mean intensity which is classically angular dependent. It has been found that the second one, the shape parameter, is also angular dependent. The K-distribution shape parameter shows two types of angular dependence. First, for rough sea floors, the parameter increases monotonously from small incident angles to grazing angles. And for a smooth seabed, after an identical increase, the shape parameter decreases for most grazing angles. In this paper, the angular dependence is first used to improve sonar images segmentation and then a new segmentation algorithm is proposed combining a probabilistic SVM-based classification outputs and a Markov-based regularization criterion. This was tested on sonar images provided by the SIMRAD EM1000 multibeam echosounder (MBES).
Design approaches for the gamification of production environments: a study focusing on acceptance

Gamification is an ever more popular method to increase motivation and user experience in real-world settings. It is widely used in the areas of marketing, health and education. However, in production environments, it is a new concept. To be accepted in the industrial domain, it has to be seamlessly integrated in the regular work processes.
 In this work we make the following contributions to the field of gamification in production: (1) we analyze the state of the art and introduce domain-specific requirements; (2) we present two implementations gamifying production based on alternative design approaches; (3) these are evaluated in a sheltered work organization. The comparative study focuses acceptance, motivation and perceived happiness.
 The results reveal that a pyramid design showing each work process as a step on the way towards a cup at the top is strongly preferred to a more abstract approach where the processes are represented by a single circle and two bars.
Critical care nurses' knowledge, attitudes and practices of oral care for patients with oral endotracheal intubation: a questionnaire survey.

AIM
This study investigated intensive care unit nurses' knowledge, attitudes and practices of oral care for intubated patients together with the associated factors of the same.


BACKGROUND
Effective oral care improves patient comfort and prevents oral infection. Although oral care is a common requirement of nursing practice, providing intubated patients with oral care is a challenging task.


DESIGN
A descriptive, cross-sectional design.


METHODS
This study applied purposive sampling method at 12 adult intensive care units in one medical centre in northern Taiwan. Two hundred and five nurses were recruited. Data were collected by structured questionnaires which consisted of four sections: knowledge, attitudes and practices of oral care for intubated patients and demographic information for the nurses.


RESULTS
The average percentages indicating the intensive care unit nurses' oral care knowledge, attitudes and practices were 58·8, 79·4 and 49·8%, respectively. Higher scores on oral care knowledge were associated with nurses performing oral care more frequently. Nurses learning about oral care from reading related studies and materials of their own accord may increase the frequency with which they provide oral care to intubated patients. The nurses' age and the type of intensive care unit they work in were significant factors related to the frequency of performing practices related to oral care.


CONCLUSION
Findings show that nurses who have more resources for learning about oral care have greater knowledge about it and provide oral care to intubated patients more frequently.


RELEVANCE TO CLINICAL PRACTICE
Encouraging nurses to learn more about oral care using diverse educational resources will enhance their knowledge and improve their practice. Nursing administrators are encouraged to establish policies and procedures for oral care of intubated patients based on the type of patients cared for, in addition to holding in-service training, with a view to enhancing the quality of oral care for critically ill patients.
Spectrum of addictions in Parkinson’s disease: from dopamine dysregulation syndrome to impulse control disorders

There is an increasing awareness that addictive disorders may occur in Parkinson’s disease (PD), either typical substance-related addictions that are commonly known as dopamine dysregulation syndrome (DDS) or behavioral addictive syndromes, usually presenting as impulse control disorders (ICDs) that include pathological gambling, hypersexuality, compulsive eating and buying. DDS is characterized by the use of dopaminergic drugs in doses larger than those required to treat motor symptoms, despite the development of disabling dyskinesias. Case reporting and prospective studies have reported an association between ICDs and the use of dopamine-agonists (DAs) at greater doses, while DDS has been associated with levodopa at greater doses or short-acting DAs. Risk factors for addictions in PD include male sex, younger age or younger age at PD onset, history of substance use or bipolar disorder, and a personality profile characterized by impulsiveness. Functional neuroimaging studies such as functional MRI and PET have investigated in vivo the neurobiological basis of these pathologic behaviors. The management for clinically significant ICD symptoms should consist of modifications to dopamine replacement therapy (DRT), particularly DAs, which is usually associated with an improvement of ICDs, whereas there is no empiric evidence supporting the use of psychiatric drugs in ICDs in PD. Management of DDS is not easy, mainly because balancing the drugs in the long term could represent a difficult problem. Hypomanic and psychotic episodes are best managed with a reduction of DRT performed in hospital also by using atypical antipsychotics low dose.
Values-based service for sustainable business-Lessons from the retailers IKEA , Starbucks , H & M and Body Shop

Aim The aim of this paper is to explore the role of values-based service for sustainable business. The two basic questions addressed are: What is ‘values-based service’? How can values create value for customers and other stakeholders? Design/ methodology/ approach This paper is based on extensive empirical studies focusing on the role of values at the corporate, country and store levels in the retail company IKEA and a comparison of the results with data from Starbucks, H&M and Body Shop. The theoretical point of departure is a business model based on the service-dominant logic (SDL) on the one hand and control through values focusing on social and environmental values forming the basis for a sustainable business. Findings Based on a comparative, inductive empirical analysis, five principles for a sustainable values-based service business were identified: (1) Strong company values drive customer value, (2) CSR as a strategy for sustainable service business, (3) Values-based service experience for co-creating value with customers, (4) Values-based service brand and communication for values resonance and (5) Values-based service leadership for living the values. A company built on an entrepreneurial business model often has the original entrepreneur’s values and leadership style as a model for future generations of leaders. However, the challenge for subsequent leaders is to develop these values and communicate what they mean today. Orginality/ value We suggest a new framework for managing values-based service to create a sustainable business based on values resonance.
The influence of depression and anxiety symptoms on health-related quality of life in patients with atrial fibrillation and atrial flutter.

BACKGROUND
The health-related quality of life (HRQoL) of patients with atrial fibrillation (AF) and atrial flutter (AFL) is an important issue in cardiovascular health management. Determinants of poor HRQoL of AF/AFL patients require further elucidation.


OBJECTIVES
The purpose of this study was to evaluate the influencing factors related to the HRQoL of AF/AFL patients.


METHODS
In 150 consecutively recruited patients in a multicenter, cross-sectional study from April 2010 to February 2011, depression and anxiety were measured with the Beck Depression Inventory II and the State Trait Anxiety Inventory, respectively, whereas HRQoL was assessed with the generic Medical Outcomes Survey 36-Item Short-Form Survey version 2 and the Symptom Checklist. Linear regression modeling was performed to determine predictors of HRQoL among variables, including the patients' age, gender, race, marital status, type of AF/AFL, frequency of AF/AFL symptoms, time since diagnosis, and anxiety and depression symptoms.


RESULTS
Female patients with AF/AFL reported poorer physical HRQoL than male patients did (P < .001, R² = 0.391). Symptoms of depression and anxiety were found to be associated with poorer HRQoL (P < .001, R² = 0.482). Anxiety was the strongest predictor of the mental component of the Medical Outcomes Survey 36-Item Short-Form Survey version 2 and the Symptom Checklist. Younger patients had worse AF/AFL-related symptoms and severity than older patients did (P < .001, R² = 0.302). Increased frequency of symptomatic episodes was associated with worse AF/AFL-related symptoms and severity.


CONCLUSION
In conclusion, depression and anxiety symptoms and female gender emerged as clear indicators of poor HRQoL in AF/AFL patients. These risk factors should be used to identify patients who may require additional evaluation and treatment efforts to manage their cardiac conditions or HRQoL. Interventions to improve HRQoL in these individuals require further investigation.
The Genome of Naegleria gruberi Illuminates Early Eukaryotic Versatility

Genome sequences of diverse free-living protists are essential for understanding eukaryotic evolution and molecular and cell biology. The free-living amoeboflagellate Naegleria gruberi belongs to a varied and ubiquitous protist clade (Heterolobosea) that diverged from other eukaryotic lineages over a billion years ago. Analysis of the 15,727 protein-coding genes encoded by Naegleria's 41 Mb nuclear genome indicates a capacity for both aerobic respiration and anaerobic metabolism with concomitant hydrogen production, with fundamental implications for the evolution of organelle metabolism. The Naegleria genome facilitates substantially broader phylogenomic comparisons of free-living eukaryotes than previously possible, allowing us to identify thousands of genes likely present in the pan-eukaryotic ancestor, with 40% likely eukaryotic inventions. Moreover, we construct a comprehensive catalog of amoeboid-motility genes. The Naegleria genome, analyzed in the context of other protists, reveals a remarkably complex ancestral eukaryote with a rich repertoire of cytoskeletal, sexual, signaling, and metabolic modules.
A Comparison and Analysis of Name Matching Algorithms

Names are important in many societies, even in technologically oriented ones which use e.g. ID systems to identify individual people. Names such as surnames are the most important as they are used in many processes, such as identifying of people and genealogical research. On the other hand variation of names can be a major problem for the identification and search for people, e.g. web search or security reasons. Name matching presumes a-priori that the recorded name written in one alphabet reflects the phonetic identity of two samples or some transcription error in copying a previously recorded name. We add to this the lode that the two names imply the same person. This paper describes name variations and some basic description of various name matching algorithms developed to overcome name variation and to find reasonable variants of names which can be used to further increasing mismatches for record linkage and name search. The implementation contains algorithms for computing a range of fuzzy matching based on different types of algorithms, e.g. composite and hybrid methods and allowing us to test and measure algorithms for accuracy. NYSIIS, LIG2 and Phonex have been shown to perform well and provided sufficient flexibility to be included in the linkage/matching process for optimising name searching. Keywords—Data mining, name matching algorithm, nominal data, searching system.
Topology control and routing in ad hoc networks: a survey

An ad hoc wireless network, or simply an ad hoc network, consists of a collection of geographically distributed nodes that communicate with one other over a wireless medium. An ad hoc network differs from cellular networks in that there is no wired infrastructure and the communication capabilities of the network are limited by the battery power of the network nodes. One of the original motivations for ad hoc networks is found in military applications. A classic example of ad hoc networking is network of war fighters and their mobile platforms in battlefields. Indeed, a wealth of early research in the area involved the development of packet-radio networks (PRNs) and survivable radio networks [16]. While military applications still dominate the research needs in ad hoc networking, the recent rapid advent of mobile telephony and plethora of personal digital assistants has brought to the fore a number of potential commercial applications of ad hoc networks. Examples are disaster relief, conferencing, home networking, sensor networks, personal area networks, and embedded computing applications [37].The lack of a fixed infrastructure in ad hoc networks implies that any computation on the network needs to be carried out in a decentralized manner. Thus, many of the important problems in ad hoc networking can be formulated as problems in distributed computing. However, there are certain characteristics of ad hoc networks that makes this study somewhat different than traditional work in distributed computing. In this article, we review some of the characteristic features of ad hoc networks, formulate problems and survey research work done in the area. We focus on two basic problem domains: topology control, the problem of computing and maintaining a connected topology among the network nodes, and routing. This article is not intended to be a comprehensive survey on ad hoc networking. The choice of the problems discussed in this article are somewhat biased by the research interests of the author.The remainder of this article is organized as follows. In Section 2, we describe various aspects relevant to modeling ad hoc networks. In Section 3, we discuss topology control. Since the nodes of an ad hoc network are often associated with points in 2-dimensional space, topology control is closely tied to computational geometry; we will briefly review this relationship and extant work in the area. In Section 4, we discuss routing protocols for ad hoc networks. After a brief overview of the many protocols that have been proposed, we discuss alternative approaches based on the adversarial network model.
Indian medical students’ perspectives on problem-based learning experiences in the undergraduate curriculum: One size does not fit all

PURPOSE
Problem-based learning (PBL) is a well-established method for facilitating the learning of basic science concepts in the context of clinical cases. Relevant evidence is lacking regarding PBL's effectiveness and acceptability as perceived by students accustomed to classical traditional teaching in India. Hence, this study gathered students' opinions on PBL versus Traditional teaching methods to generate a foundation for institutional policymaking and ultimately, changes in the policy of regulatory bodies.


METHODS
A total of 773 first year medical students admitted from 2007-2010 in Kasturba Medical College Manipal, Manipal University, India were asked to respond to a 15-item questionnaire evaluating their preferences for PBL or traditional methods such as lectures after undergoing a systematically conducted PBL session in physiology. Their responses were analyzed with an unpaired t-test. Their comments were also collected.


RESULTS
PBL scored significantly higher for most items in the questionnaire for "learning efficiency" and "student-teacher relationship". The students' comments highlighted the importance of a trained tutor/facilitator to enhance the learning process.


CONCLUSION
Our students are willing to adapt to the PBL method, although they recognize certain benefits of traditional pedagogy. For learning efficiency and the student-teacher relationship, the students feel that neither method holds an advantage. We recommend that the future medical curriculum in India be a hybrid form of PBL and traditional methods with specific training on the unfamiliar PBL approach for both faculty and students.
Integrating Lean, Agile, Resilience and Green Paradigms in Supply Chain Management (LARG_SCM)

1.1 What is the problem? Different management paradigms, such as the lean, agile, resilience and green have been adopted for the management of supply chains. The lean supply chain is a paradigm based on cost reduction and flexibility, focused on processes improvements, through the reduction or elimination of the all “wastes”, i.e., non-value adding operations (Womack et al., 1991). It embraces all the processes through the product life cycle, starting with the product design to the product selling, from the customer order to the delivery (Anand & Kodali, 2008). The agile supply chain paradigm intends to create the ability to respond rapidly and cost effectively to unpredictable changes in markets and increasing levels of environmental turbulence, both in terms of volume and variety (Agarwal et al., 2007). However, when organizations are subject to eventual disruptions, caused by sudden and unforeseen events (like economic and politic crisis or environmental catastrophes), the lean practices may have contributed to rupture conditions (Azevedo et al., 2008). In a global economy, with supply chains crossing several countries and continents, from raw material to final product, those events (even if they happen in a remote place) can create large-scale disruptions (Craighead et al., 2007). These disruptions are propagated throughout the supply chain, causing severe negative effects in supply chains leading to unfulfilled orders. So, it seems that what can be good from the competitive point of view, can cause a disaster on crisis situations; it may be worst if the organizations can not be resilient and robust enough to recover the loosed competitiveness. In actual competitive market, it is necessary that supply chains become more resilient to disruption events (Sheffi & Rice, 2005; Tang, 2006). Other pertinent issue in supply chain management is the environmental sustainability. The green supply chain management is as an important organizational philosophy to achieve corporate profit and market share objectives by reducing environmental risks and impacts while improving ecological efficiency of these organizations and their partners (Rao & Holt, 2005; Zhu et al., 2008). As a synergistic joining of environmental and supply chain management, the competitive and global dimensions of these two topics cannot go unnoticed by organizations.
