Validation of a Spanish Version of the Mental Health Continuum-Short Form Questionnaire.

BACKGROUND The Mental Health Continuum-Short Form (MHC-SF) is a multidimensional measure of well-being designed to assess emotional, psychological and social well-being. It has been translated into different languages; however, there is no validated Spanish version. Our aim was to provide the Spanish-speaking community with a validated version of the MHC-SF. METHOD We translated the questionnaire into Spanish (s-MHC-SF) and assessed its validity in a sample of 3,355 Chilean adults. The data was subjected to a confirmatory factor analysis using the original correlated-traits three-factor model and a recently described bifactor model. RESULTS The scores obtained with s-MHC-SF had excellent reliability (α = .94). While the correlated-traits three-factor model provided an acceptable fit to the data, the bifactor model yielded a superior fit. According to measurement invariance results, both models could be used to compare scores over gender, geographical region, age, and time in the sample. CONCLUSION s-MHC-SF is a valid questionnaire for the evaluation of personal well-being in Spanish-speaking populations.

Secure Clocked QCA logic for implementation of Quantum Cryptographic Processors

Since the introduction of side-channel attacks, cryptographic devices have been highly susceptible to power and electromagnetic analysis attacks; because these attacks require only relatively inexpensive equipments. Unless adequate countermeasures are implemented, side channel attacks allow an unauthorized person to reveal the private key of a cryptographic module. As a new countermeasure a novel logic approach to implement cryptographic processors in, named Secured Clocked Quantum-dot Cellular Automata (SCQCA) logic has been presented. The proposed logic takes advantage of low power consumption Quantum-dot Cellular Automata together with complicated clocking schemes as a paradigm of nanotechnology advances in cryptography engineering.
Sjögren’s syndrome patients presenting with hypergammaglobulinemia are relatively unresponsive to cevimeline treatment

Sjögren’s syndrome (SS) is a systemic autoimmune disease characterized by sicca symptoms, including dry eyes and dry mouth. Cevimeline is used for the treatment of dry mouth in patients with SS. Here we prospectively tested the clinical effectiveness of cevimeline at increasing saliva secretion in patients with SS, and the results were compared with the clinical parameters of the patients. Saliva secretion was increased >160% in 17 of 30 (56.7%) patients (P < 0.005). When the clinical parameters were compared between the patients who responded to cevimeline treatment and those who did not respond to the treatment, the frequency of patients presenting with hypergammaglobulinemia was significantly higher in the nonresponder group (P < 0.05). It thus appears that cevimeline is effective in SS patients with milder disease activity.

How banks and fintechs create and capture value with mobile payment via their business value network: A value network case study of ING’s Mobiel Betalen and WeChat Pay’s Quick Pay.

Network value analysis of mobile payment solutions has shown that in order to deliver value and create the service, a network of partners is required. Solutions of different providers, banks and fintechs, have shown that both have similar network partners in place. Common partners among mobile payment solutions are banks or actors with a payment license, smartphone manufacturers, stores, merchants and generally places that accept mobile payments. Depending on the technology that got chosen by the payment provider, further actors are part of the network. All actors within the network receive their own individual value by being part of the network. Mobile payment solutions that make use of quick response (QR) codes for payments are easier to facilitate than payment solutions that make use of near field communication (NFC). This is due to that users and merchants simply need a unique QR code that is connected to their mobile payment account, while payment solutions that make use of NFC technology need payment terminals that facilitate contactless payments as well as a suitable smartphone. By limiting the payment solution to only certain smartphones, payment terminals and operating systems, providers limit their potential user base. Even though multiple network partners of the fintech and bank payment solution got distinguished, some value chain elements still remain, as the parent companies of both take on multiple task and functions of the network. Nonetheless, without the networks in place, banks and fintechs cannot deliver value as crucial parts that are needed for delivering the service and making the product work are done by other actors within the network.
Success factors for ICT shared services in higher education institutions

Shared service is a consolidation of support functions in an organization, to provide services as efficiently and effectively as possible. The implementation of shared services in an organization becomes crucial particularly with reference to ICT shared services. However, there is a deficiency in the means of measuring the extent of successful ICT shared services. The purpose of this study is to identify the factors that influence the success of ICT shared services and determine the level of ICT shared services implementation. The study uses a systematic literature review (SLR) to identify the factors characterizing the success of the ICT shared services model. The content of this study was acquired from various resources including papers and books, which were used to find the ICT shared services factors. The SLR revealed six factors which influence the success of ICT shared services in the organization. These factors are organized using multiple theories which are split into three different perspectives: technologies, organizational and the personnel responsible for producing the ICT shared services model. This study deploy a questionnaire survey method to evaluate the initial success factor and using Descriptive Statistics to validate the data.
Consumer Demand for Domestic and Imported Broiler Meat in Urban Ghana: Bringing Non-Price Effects into the Equation

Ghana’s domestic poultry industry is one of many in West Africa that is seeking strategies to compete with imported poultry products. This study investigates if urban Ghanaian consumers are willing to pay for non-price attributes in poultry; hence, offering potential competitive niches. Consumer preferences in Accra, Ghana for domestic and imported chicken were studied using a choice based conjoint analysis. A total of 138 respondents who were directly purchasing broiler products were drawn randomly from both traditional and modern markets for inclusion into a revealed preference data collection. A conditional logistic regression model was used to estimate the part-worth of attributes of both domestic and imported broiler meat. The study reveals that purchase decisions are not entirely based on price, but also non-price attributes such as convenience, freshness and origin of the product. In the case of Ghana, consumers prefer imported chicken on the basis of convenience, as imported chicken is primarily offered as pre-cut pieces, and domestic chicken on the basis of taste and origin. The findings suggest that there is an opportunity to market domestic chicken on attributes in addition to price such as convenience and origin. To take advantage of this opportunity, investment in the domestic poultry industry is required, across the supply chain from processing to marketing.
Influence of arsenic and cyanobacteria co-exposure on plasmatic parameters of rainbow trout (Oncorhynchus mykiss W.).

OBJECTIVES Fish can be exposed under environmental conditions to multiple stressors including natural toxins and environmental or feed contamination at the same time. This study brings new knowledge about the effects of controlled exposure to multiple stressors in fish. The aim of this study was to test the hypothesis that influence of cyanobacterial biomass and arsenic in feed can combine to enhance the effects on fish. METHODS Rainbow trouts were sorted into six groups, each with 25 specimens: control group (fed with commercial feed), groups exposed to toxic cyanobacterial biomass (81 mg x kg(-1) MCs of feed), two groups exposed to arsenic (concentration of 5 mg x kg(-1), and 50 mg x kg(-1) of fish feed) and two groups exposed to combination of cyanobacterial biomass and arsenic in two concentrations mentioned above. The experiment lasted 30 days. During the experiment we evaluated the influence of co-exposure on plasmatic parameters mentioned above. Samples were collected on days 10, 20 and 30 of exposure. RESULTS Biochemical analysis revealed a significant decrease in calcium (T20) and an increase in natrium (T10) and chlorides (T10) values in combined cyanobacterial and arsenic exposures. Our results showed a significant decrease in the values of magnesium after exposure to higher concentration of arsenic compared to control and feeding with addition of cyanobacterial biomass groups. The changes of other monitored plasmatic parameters were not significantly increased or decreased in comparison with controls. CONCLUSIONS Our results confirmed the hypothesis that influence of toxic cyanobacterial biomass and a chemical agent represented by arsenic can combine to enhance the effects on fish. This work originally shows that while the single agents in sub-lethal doses do not cause changes in the plasmatic parameters, their co-exposure leads to the significantly decrease or increase of the electrolytes of rainbow trout.
A decision theoretic foundation for indexing

The indexing of a document is among the most crucial steps in preparing that document for retrieval. The adequacy of the indexing determines the ability of the system to respond to patron requests. This paper discusses this process, and document retrieval in general, on the basis of formal decision theory. The basic theoretical approach taken is illustrated by means of a model of word occurrences in documents in the context of a model information system; both models are fully defined in this paper. Though the main purpose of this paper is to provide insights into a very complex process, formulae are developed that may prove to be of value for an automated operating system. The paper concludes with an interpretation of recall and precision curves as seen from the point of view of decision theory.
Adaptive Legged Robots Through Exactly Constrained and Non-Redundant Design

This paper presents a novel strategy for designing passively adaptive, statically stable walking robots with full body mobility that are exactly constrained and non-redundantly actuated during stance. In general, fully mobile legged robots include a large number of actuated joints, giving them a wide range of controllable foot placements but resulting in overconstraint during stance, requiring kinematic redundancy and redundant control for effective locomotion. The proposed design strategy allows for the elimination of actuation redundancy, thus greatly reducing the weight and complexity of the legged robots obtained and allowing for simpler control schemes. Moreover, the underconstrained nature of the resulting robots during swing allows for passive adaptability to rough terrain without large contact forces. The strategy uses kinematic mobility analysis tools to synthesize leg topologies, underactuated robotics design approaches to effectively distribute actuation constraints, and elastic elements to influence nominal leg behavior. Several examples of legged robot designs using the suggested approach are thoroughly discussed and a proof-of-concept of a non-redundant walking robot is presented.
Genetic structure in northeastern populations of the Alpine newt (Triturus alpestris): evidence for post‐Pleistocene differentiation

Genetic variation in 13 populations of the Alpine newt, Triturus alpestris, was assessed at the northeastern margin of its range (southern Poland). Variation at six microsatellite loci was scored in 354 newts, and two mitochondrial DNA fragments (c. 2000 bp) were sequenced in a subset of 27 individuals. Significant differences in allele frequencies and the presence of private alleles determined genetic units corresponding to three separate mountain ranges, i.e. the Carpathian, Sudetes and Holy Cross Mountains. FST's were three times greater in among than in within mountain range pairwise comparisons. An assignment test and pairwise FST's suggested relatively high levels of gene flow at the local level, although the Sudetes populations revealed some subtle structuring. Genetic variation was lower in the Carpathians and Holy Cross Mountains. The geographic pattern of mitochondrial DNA variation indicated that these newt populations originated from a single glacial refugium/founder population, and that the colonization of southern Poland took place in an easterly direction. The data show that substantial neutral variation and between group divergence has accumulated relatively quickly in these low‐vagility organisms. The Alpine newt case exemplifies species history as a factor determining patterns of genetic diversity in marginal populations.
Cerebral Microembolism Detected by Transcranial Doppler During Cardiac Procedures

Background and Purpose Cerebral embolism with clinical sequelae may rarely complicate cardioversion and cardiac catheterization. Transcranial Doppler sonography has recently been introduced to monitor microemboli entering the middle cerebral artery in cardiac and carotid surgery. We therefore used this technique to evaluate the risk of asymptomatic embolism during common cardiac procedures. Methods Patients were monitored by transcranial Doppler while undergoing direct current cardioversion (n=15) and cardiac catheterization (n=17). Results Microemboli were detected in all patients having cardiac catheterization but in only 1 patient after cardioversion. Conclusions Microembolism occurred frequently during cardiac catheterization and rarely during cardioversion. It is not yet known whether this has clinical relevance.
Perspectives on public awareness of stroke and aphasia among Turkish patients in a neurology unit

Recent studies on awareness have drawn attention to the fact that aphasia is a little known disorder to the public, in spite of all the publicity about this frequently occurring neurogenic language disorder. Being a very new concept, studies of awareness are rare in Turkey. This survey study assessed the extent of public awareness of neurological disorders, including aphasia, and information sources to answer questions about such disorders. A survey questionnaire consisting of 22 brief questions divided into three sections of awareness was administered to a convenience sample of 196 adults at a University Hospital in 2004. The results indicated that epilepsy and dementia are “the most well‐known”, and Multiple Sclerosis (MS) is “the least‐known” among the surveyed diseases/disorders. Aphasia awareness was also low. The respondents preferred doctors as the most reliable information source. Speech and language therapists were found to be one of the information sources in advocating publicity as well. Most respondents expected to receive information from the doctors; who, in Turkey, are totally occupied with the physical aspects of health care provision. Neurologists, in collaboration with speech and language therapists, should be in a position to develop educational programmes to increase public awareness.
Effect of the Dot Separation on the Switching Behavior of Ni-Fe Elliptical Dot Arrays

We have studied the effect of the dot separation on the switching behavior of Ni-Fe elliptical dot arrays with major axial distances between the adjacent dots. The magnetization process and the magnetic configuration in the dot arrays apparently differ according to the distance between the adjacent dots. These differences are due to the fact that the dipole-dipole interaction becomes stronger while decreasing the major axial distance between the adjacent dots. From these results, it is evident that the optimal distance at which the magnetization between the adjacent dots couples by the dipole-dipole interaction is below 30 nm.
A low phase noise 19 GHz-band VCO using two different frequency resonators

A low phase noise 19 GHz-band VCO is presented in this paper. The VCO has a novel tuning circuit consisting of two resonators which have a different resonant frequency. With these two resonators, the Q factor of the tuning circuit of the VCO is improved, and low phase noise can be achieved. The measurement results of the developed VCO show phase noise from -120 dBc/Hz to -122 dBc/Hz at 1 MHz from the carrier over a 290 MHz tuning bandwidth in the 19 GHz-band. This VCO achieves one of the lowest recorded values of phase noise at K-band.
[A shortened form of the Spanish Boston naming test: a useful tool for the diagnosis of Alzheimer's disease].

INTRODUCTION The Boston Naming Test (BNT) is the most frequently used test of confrontation naming. Due to its length, several abbreviated forms have been proposed. OBJECTIVE The aim of the study was to develop a short form for the Spanish version of the BNT that could detect early semantic changes in Alzheimer s disease (AD). PATIENTS AND METHODS One hundred and three patients with diagnosis of probable AD (NINCDS ADRDA criteria), with GDS< 5 and 143 normal subjects, matched for age and education, were studied. Subjects with <4 years of education were excluded. No subject had any history of neurological of psychiatric disorders or alcohol abuse. All participants underwent a comprehensive neuropsychological assessment which included the 60 item Spanish version of the BNT. The sensibility and specificity of each item and demographic effect s variability were calculated (ANOVA). Those 12 figures with the highest sensibility and specificity which showed no significant educational or age variation were administered to all participants. The Spearman correlation coefficient was used. RESULTS Mean score for the control group was 11 (standard deviation: 1.16). No significant effects for age (r= 0.14574) or education (r= 0.101293) were found. The sensibility and specificity for correctly diagnosing AD was 85% and 94% respectively, similar to the longest version. CONCLUSION This 12 item version of the BNT can be a useful instrument for a rapid screening of AD, as it is as sensible and specific as the 60 item version, and it is not influenced by age or education.
Human Monoclonal Antibodies Isolated from Type I Diabetes Patients Define Multiple Epitopes in the Protein Tyrosine Phosphatase-Like IA-2 Antigen

Protein tyrosine phosphatase-like IA-2 autoantigen is one of the major targets of humoral autoimmunity in patients with insulin-dependant diabetes mellitus (IDDM). In an effort to define the epitopes recognized by autoantibodies against IA-2, we generated five human mAbs (hAbs) from peripheral B lymphocytes isolated from patients most of whom had been recently diagnosed for IDDM. Determination and fine mapping of the critical regions for autoantibody binding was performed by RIA using mutant and chimeric constructs of IA-2- and IA-2β-regions. Four of the five IgG autoantibodies recognized distinct epitopes within the protein tyrosine phosphatase (PTP)-like domain of IA-2. The minimal region required for binding by three of the PTP-like domain-specific hAbs could be located to aa 777–979. Two of these hAbs cross-reacted with the related IA-2β PTP-like domain (IA-2β aa 741-1033). A further PTP-like domain specific hAb required the entire PTP-like domain (aa 687–979) for binding, but critical amino acids clustered in the N-terminal region 687–777. An additional epitope could be localized within the juxtamembrane domain (aa 603–779). In competition experiments, the epitope recognized by one of the hAbs was shown to be targeted by 10 of 14 anti-IA-2-positive sera. Nucleotide sequence analysis of this hAb revealed that it used a VH germline gene (DP-71) preferably expressed in autoantibodies associated with IDDM. The presence of somatic mutations in both heavy and light chain genes and the high affinity or this Ab suggest that the immune response to IA-2 is Ag driven.
