Role stress and work engagement as antecedents of job satisfaction in Spanish workers

Purpose: According to the Job Demands-Resources (JDR) model, engagement and job satisfaction may be produce by two types of working conditions: job demands (i.e. role stress) and job resources (i.e. self-efficacy). This study examines the role of role stress and work engagement as antecedents of job satisfaction in a sample of Spanish workers. Design/methodology/approach: This study comprised a sample of 435 Spanish workers. A cross sectional study was used to examine the relationship between role stress, work engagement and job satisfaction. Data were gathered based on personal administered questionnaires. Findings and Originality/value: Hierarchical multiple regression models have revealed that job satisfaction was significantly predicted by role stress and work engagement. Results support JDR model by showing that positive outcomes, such as job satisfaction can be predicted by motivational process and job demands. Research limitations/implications: The cross-sectional design cannot evidence of causal relationships. This study relies on self-reports, which might increase the risk of common method variance. Practical implications: On a practical level, the JDR model provides a framework for understanding motivating workplaces and engaged and satisfied employees. Originality/value: The JDR model could be useful in designing strategies for which engaged employees may be advantageous to improving the quality of services, while at the same time increasing employees’ job satisfaction and well-being.
TALE-mediated inhibition of replication of begomoviruses.

During the last decade, unprecedented progress in the field of genome modification has been witnessed with various applications in basic and applied biology. Genome editing with specific DNA binding proteins has shown higher specificity and fidelity. Artificially engineered proteins such as zinc fingers (ZFs), transcription activator-like effectors (TALEs) and clustered regularly interspaced short palindromic repeats (CRISPR) RNA-guided nucleases (e.g., Cas9) have been used to edit genomes of several plants species such as wheat, rice, soybean, potato, tomato, tobacco, Arabidopsis etc. Engineered proteins with nuclease domain, ZFNs, TALENs, CRISPR/Cas9, can be used to induce double-strand breaks (DSB) in the target genomes. In eukaryotic systems, double strand breaks are repaired by either non-homologous end joining (NHEJ) or homologous recombination (HR) based repair mechanisms resulting in knockdown or malfunction of the targeted gene. Begomoviruses are becoming a serious threat to a number of crops in Pakistan. The present study was initiated with the objective to demonstrate suppression of replication of cotton leaf curl virus (CLCuV) using TALE technology. The most conserved DNA sequence of begomoviruses, nonanucleotide, was targeted to achieve a broad-spectrum resistance against CLCuV prevalent in Pakistan. Activity of TALEs for virus suppression was successfully demonstrated in Nicotiana benthamiana by challenging with infectious clones of cotton leaf curl Kokhran virus (CLCuKV). Virus accumulation was determined by qPCR. The plants showed varying degrees of resistance to CLCuKV in three ways; attenuated virus infection, delayed symptoms and lower virus titer. Our results successfully demonstrated the potential of TALE technology for CLCuV suppression and offer a broader genome targeting platform for suppression of other viruses. © 2018 Friends Science Publishers
Sexually Dimorphic Cubomedusa Carybdea sivickisi (Cnidaria: Cubozoa) in Seto, Wakayama, Japan

The small but distinctive cubomedusa Carybdea sivickisi has been reported from a range of tropical, subtropical, and mild temperate localities in the Pacific. In Japan, it has only definitively been documented in the subtropical region of Okinawa. However, in 1970 Uchida noted that three specimens from Seto, Wakayama, which he had referred to as Tamoya alata in 1929, were really C. sivickisi. The presence of this species as far north as Wakayama was questionable because of the confusion about the identity of the specimens and the fact that C. sivickisi had never been observed subsequently in this region. In August 2006, we discovered a population of this tiny species nearby the Seto Marine Biological Laboratory in Shirahama, Wakayama. In this paper we comment and clarify the geographical range, developmental morphology, and sexual behaviour of this species.
A Model of Culture Incorporation in Language Teaching

Cultural content has become an important issue after the advent of intercultural communicative approach (ICC) in language teaching field. The current study analyzed cultural content of three mainstream intermediate level EFL textbooks. This study was carried out using Chen’s (2004) and Lee’s (2009) suggested themes for detecting big “C” and little “c” culture aspects. Big C represents series of statistics and facts such as art, geography, history, education, festivals, and customs of the target speech community; small c represents norms, beliefs, sociocultural variables such as age, sex, and social position (Lee, 2009). This study also analyzed the cultural categories including target culture, source culture and international culture based on Cortazzi and Jin’s (1999) category and another category i.e. neutral culture based on Aliakbari’s (2004) category. This was a qualitative-quantitative study and chisquare test was applied in it. It was found that generally both little “c” and big “C” are present in the textbooks. However, in all the three textbooks little “c” has gained higher frequency than big “C”. It was also revealed that the percentage of little “c” in Top Notch is more than other books and little “c” percentage in Four Corners is the least.
Study of B→πℓν and B→ρℓν decays and determination of |Vub|

We present an analysis of exclusive charmless semileptonic B-meson decays based on 377×106 BB pairs recorded with the BABAR detector at the Υ(4S) resonance. We select four event samples corresponding to the decay modes B0→π-l+ν, B+→π0l+ν, B0→ρ-l+ν, and B+→ρ0l+ν and find the measured branching fractions to be consistent with isospin symmetry. Assuming isospin symmetry, we combine the two B→πlν samples, and similarly the two B→ρlν samples, and measure the branching fractions B(B0→π-l+ν)=(1.41±0.05±0.07)×10-4 and B(B0→ρ-l+ν)=(1.75±0.15±0.27)×10-4, where the errors are statistical and systematic. We compare the measured distribution in q2, the momentum transfer squared, with predictions for the form factors from QCD calculations and determine the Cabibbo-Kobayashi-Maskawa matrix element |Vub|. Based on the measured partial branching fraction for B→πlν in the range q2<12 GeV2 and the most recent QCD light-cone sum-rule calculations, we obtain |Vub|=(3.78±0.13-0.40+0.55)×10-3, where the errors refer to the experimental and theoretical uncertainties. From a simultaneous fit to the data over the full q2 range and the FNAL/MILC lattice QCD results, we obtain |Vub|=(2.95±0.31)×10-3 from B→πlν, where the error is the combined experimental and theoretical uncertainty.
The Psychometric Properties of the Scale of Body Connection (SBC) in a Portuguese Sample

Aim: The Scale of Body Connection (SBC) is a measure aimed at examining body awareness (BA), specifically awareness of inner body sensations, and bodily dissociation (BD), or the sense of separation from the body. The aim of this study was to develop a Portuguese version of the SBC. Method: An online survey was completed by 445 women, with an average age of 30.47 (SD = 9.87), and 464 men, with an average age of 37.54 (SD = 12.34). Ages ranged from 18 to 72 years old. Results: Results showed Cronbach’s alpha coefficients of . 86 for BA and . 73 for BD. Confirmatory factor analysis revealed reasonable goodness-of-fit indices (χ2/df = 9.0; GFI = .84; NFI = .72; CFI = .74; PGFI = .68; PCFI = .66; RMSEA = .09). Conclusion: Positive correlations between the SBC factor scores and the scores of the General Body Dissatisfaction Scale and the Cognitive Distraction Scale confirmed convergent validity. These findings support the reliability and validity of the SBC in a Portuguese sample.
Framing Social Values: An Experimental Study of Culture and Cognition

How and why does a given social value come to shape the way an individual thinks, feels, and acts in a specific social situation? This study links ideas from Goffman's frame analysis to other lines of research, proposing that dramatic narratives of variable content, vividness, and language-in-use produce variation in the accessibility of schematic, internal cultural frameworks, and, thereby, variation in the social value frames that gain situational primacy. Hypotheses derived from the argument are experimentally supported, and results encourage further research on the process of social value framing, which operates as a person crosses boundaries in the complex subcultural mosaic.
Bayesian Inference for Matched Case-Control Studies

The paper introduces general Bayesian inference procedures for the analysis of matched casecontrol data. The general results hold for a wide class of likelihoods and priors. A real life example is considered to illustrate the methodology. Also, for the logistic regression model, we have shown how Bayesian inference based on the unconditional likelihood can dier substantially from one based on the conditional likelihood.
Using the Risk Ratio to Assess Racial/Ethnic Disproportionality in Special Education at the School-District Level

The issue of the disproportionate identification and placement of racial/ethnic minorities in special education has been investigated extensively. One of the most useful tools in this research is the risk ratio, which compares one racial/ethnic group's risk of receiving special education and related services to that of all other students. The risk ratio can be used to calculate disproportionality at both the state and school-district levels. However, analysts often encounter difficulties in applying the risk ratio to district-level data due to variable demographic distributions and small numbers of students in either the racial/ ethnic group or the comparison group. We propose two modifications to the risk ratio for dealing with these problems.
Multi-criteria approach for customer trust model in internet banking: a case of UTM CIBM bank

One of the critical factors having influence on accomplishment of internet banking services is the trust of the customer. To achieve customer trust depends on different factors that internet banking struggle to control. The purpose of this research is to clarify the particular interrelationships existing between customer's online trust and other associated variables such as satisfaction, loyalty, competence, integrity and benevolence. In addition, a model of consumer's trust in internet banking which depends on the investigation regarding previous studies has been developed. To examine the model a type of descriptive survey is applied. According to similar studies already done, the survey sample population is selected equal with 318 that is randomly obtained from students in UTM. By testing the correlation, the results of study indicated that most of UTM students are satisfied with internet banking services. Furthermore, the results showed that the trust correlation with satisfaction, competence, loyalty, benevolence and integrity is positive. Moreover, from the multi-criteria perspective, we evaluated the incorporated factors in the developed model and ranked them by TOPSIS method. By TOPSIS the weight of ranking for loyalty, satisfaction, benevolence, competence and integrity were 0.25, 0.213, 0.201, 0.184 and 0.152. We hope the current study could be helpful to eliminate the problems existing around sensitive subject of the trust.
REFERENCE-BASED PREDICTION MEASURES

This paper presents research on the use of methods for end-to-end speech quality assessment for the perceptual evaluation of text-to-speech (TTS) systems. We analyze the ITU-T Rec. P.862. 2 Wideband Perceptual Evaluation of Speech Quality (WB-PESQ) as well as its wideband optimized successor ITU-T Rec. P.863 Perceptual Objective Listening Quality Assessment (POLQA), and the Diagnostic Instrumental Assessment of Listening quality (DIAL) algorithm (Côté et al., PQS 2010). All measures were originally optimized for the evaluation of telephone networks and speech codecs; thus they are used out of their original domain. In addition to the to-be-evaluated TTS signal all measures also need a natural speech reference as input. The quality estimate is calculated by comparing the natural reference with its corresponding synthetic speech signal. The measures are tested on data collected by the Blizzard Challenge (BC) in the past years. BC is a competition for developers of speech synthesis systems with the intent to train different systems on the same speech corpus and evaluate their performance. Thus, all synthesizers were built on the same voice. We use the natural speech reference and its corresponding TTS signal as input for the above mentioned measures. The correlation between the calculated mean opinion score (MOS) and the perceptually evaluated quality rating serves as an indicator for the accuracy of the prediction. The achieved results were disappointing throughout all databases. The main problem of all 3 algorithms seems to be an inaccurate time alignment between the natural speech file and its corresponding TTS sample. To fix this problem we propose a Dynamic Time Warping between both signals prior to the reference-based evaluation.
Heterogeneous welfare dynamics and structural transformation in Tanzania

Whether for the purpose of national policy setting or for localized targeting, understanding the welfare dynamics of a population is essential for the efficient allocation of limited resources as well as to avert unintended consequences. However, the literature on welfare dynamics largely focuses on population means and two-technology economies, either by conducting analyses in single-asset economies or by relying on theoretical models and simulations with a number of restrictive assumptions. Likewise, the literature on the structural transformation generally imposes an agricultural/non-agricultural dichotomy on the data. These approaches may overlook the plights or prospects of heterogeneous subgroups in developing economies. Using a theoretically grounded, data driven approach to identifying a livelihood strategy choice set in a flexible manner, I estimate livelihood and migration conditioned returns to assets and associated welfare dynamics using a long panel dataset from Kagera, Tanzania. I find that, between 1991 and 2004, a subset of households moves from the dominant, farm-based, livelihood to a livelihood that allocates more assets to off-farm wage and entrepreneurial activities. In estimating marginal returns to assets across livelihoods, I find significant differences in returns to business, labor, and human capital assets by livelihood strategy, suggesting that households might realize locally increasing returns if they could switch livelihoods. Analysis of welfare dynamics across livelihoods suggests conditional convergence and uncovers heterogeneous welfare dynamics that would be masked in an analysis of population mean dynamics alone. Although beginning with a flexible framework and employing a data driven strategy, the analysis applied here confirms many of the stylized facts of the structural transformation literature, in particular the emergence of two sectors, sector-differentiated returns to labor and other factors, and catch up in the low return sector.

Ipak, to sto oboljeli od RAU-a imaju hematoloske deficite jos je uvijek kontroverzno pitanje, kao i utjecaj stresa na pojavu rekurentne aftozne ulceracije. Ispitanici i postupci: Od 30 bolesnika s RAU-om (36,27 ± 15,308 godina) i 30 kontrolnih ispitanika (29,83 ± 9,082 godina) uzeto je po pet mililitara krvi kako bi se odredile vrijednosti željeza, vitamina B12 i folne kiseline te po dva mililitra sline zbog određivanja vrijednosti salivarne alfa-amilaze enzimskim imunotestom. Svi sudionici ispunili su i ljestvicu stresa. Rezultati: Prema rezultatima ovog istraživanja nije bilo razlika u vrijednostima serumskog željeza, vitamina B12 i folne kiseline između bolesnika s RAU-om i sudionika u kontrolnoj skupini. Osim toga nije bilo razlika ni u razini salivarne alfa-amilaze između bolesnika s RAU-om tijekom akutne faze i remisije u usporedbi s kontrolnom skupinom, kao sto nije bilo razlike u broju stresnih događaja između 3 ispitane skupine. Zakljucak: Kod oboljelih od RAU-a nije indicirano rutinsko određivanje navedenih hematoloskih parametara. Nadalje, razina salivarne amilaze i ljestvica stresa ne pokazuju da su pacijenti s RAU-om vise u stresu od sudionika u kontrolnoj skupini.

A preliminary simulation model of individual and synergistic impacts of elephants and fire on the structure of semi-arid miombo woodlands in northwestern Zimbabwe

Sustainable management of plant-herbivore systems requires an understanding of their long-term dynamics through modeling approaches. A preliminary simulation model was developed using STELLA to predict the impacts of elephants and fire on the structure of semi-arid miombo woodlands of northwestern Zimbabwe. Elephants alone at a density of 0.27 km -2 will convert the woodland into coppice in 120 years due to resulting massive declines of large trees. The same result is achieved in only 10 years if elephant density is at 2 km -2 . The pattern remains similar with simultaneous application of fire once every 4.7 years with elephants at 0.27 km -2 . When elephants are culled at 30% whenever their densities reach 1 km -2 , the woodland does not degenerate into coppice despite fire occurrence once every 4.7 years. Therefore, elephants alone can degrade and maintain semi-arid miombo woodland into coppice, largely due to their damaging impacts on mature canopy trees and fire acts to speed up the process by suppression of an already low recruitment. Fire alone has a lesser influence on woodland structure than elephants because of low fuel loads due to heavy grazing and low grass production as a result of low rainfall and inherently poor soils in the area. A maximum elephant density of 0.1 km -2 is recom-mended to achieve equilibrium in the area.

DERIVATION / VALIDATION OF COLLISION CROSS SECTIONS FOR IONS AND ELECTRONS IN GASES FROM MEASURED SWARM

This paper presents a few selected cases of recent experimental work on the measurement of transport and reaction properties of electron and ion swarms in gases and their usefulness to either validate or derive sets of collision cross sections which are essential for the understanding, simulation and modelling of many types of gas discharges. The paper discusses several key examples of measured electron/ion drift velocities (mobilities), longitudinal diffusion coefficients, effective ionization coefficients, and ion-molecule reaction rates with gases through which new sets of cross sections have been obtained. All the systems discussed contemplate the measurement of the pure gas and its mixture with N2 or rare gases for which reliable cross section sets are well known, thereby serving as a test to the newly derived cross sections for the pure gas.
A Security Analysis of Honeywords

Honeywords are decoy passwords associated with each user account, and they contribute a promising approach to detecting password leakage. This approach was first proposed by Juels and Rivest at CCS’13, and has been covered by hundreds of medias and also adopted in various research domains. The idea of honeywords looks deceptively simple, but it is a deep and sophisticated challenge to automatically generate honeywords that are hard to differentiate from real passwords. In JuelsRivest’s work, four main honeyword-generation methods are suggested but only justified by heuristic security arguments. In this work, we for the first time develop a series of practical experiments using 10 large-scale datasets, a total of 104 million real-world passwords, to quantitatively evaluate the security that these four methods can provide. Our results reveal that they all fail to provide the expected security: real passwords can be distinguished with a success rate of 29.29%∼32.62% by our basic trawling-guessing attacker, but not the expected 5%, with just one guess (when each user account is associated with 19 honeywords as recommended). This figure reaches 34.21%∼49.02% under the advanced trawling-guessing attackers who make use of various state-of-the-art probabilistic password models. We further evaluate the security of Juels-Rivest’s methods under a targeted-guessing attacker who can exploit the victim’ personal information, and the results are even more alarming: 56.81%∼67.98%. Overall, our work resolves three open problems in honeyword research, as defined by Juels and Rivest.
