A New Blind Signature Scheme Based on Improved ElGamal Signature Scheme

Blind signature scheme, an important cryptographic primitive, is applicable in protocols that guarantee the anonymity of the participants. This scheme is increasingly used in untraceable payment and electronic voting systems. In this paper we improve ElGamal signature scheme and then we propose a new blind signature based on that. ElGamal signature scheme has an important advantage into RSA signature scheme which is non-deterministic and means that there are many valid signatures for any given message. This property also exists in our new blind signature scheme. Having low computational complexity for signature requester and the signer is one of the advantages of the newly developed scheme and as a result makes it very efficient.
Occurrence of Four Major Perennial Grasses in Relation to Edaphic Factors in a Pristine Community

Highlight: The ecology and phytosociology of a virgin grassland community (Virginia Park, Canyonlands National Park, Utah) have been investigated. Based on the use of C x F index, Hilariajamesii and Stipa comata are the most abundant of the four major perennial grasses. Oryzopsis hymenoides and Sporobolus cryptandrus are less abundant in decreasing order. The sites dominated by Hilaria are characterized by soils with finer texture, slightly warmer average temperature and higher surface K+ and organic matter compared to sites dominated by Stipa comata. In addition, frequency of both vascular and cryptogamic species is greater on sites dominated by Hilaria.
Productive performance of broiler breeder hens fed 25-hydroxycholecalciferol

Foi realizado um experimento com o objetivo de avaliar a suplementacao de 25-hidroxicolecalciferol (25(OH)D3) associado a vitamina D3 em dietas para reprodutoras de frangos de corte. Foram alojadas matrizes Cobb 500 em delineamento completamente casualizado, composto de quatro tratamentos e oito repeticoes de 20 femeas e 2 machos. Os tratamentos experimentais foram constituidos de premixes vitaminicos contendo 2.000 e 3.400 UI/kg racao de vitamina D3 como unica fonte ou 2.000 UI D3 associado a 35 ou 69 mg/t de 25(OH)D3. Nao houve efeito da suplementacao de 25(OH)D3 sobre a producao de ovos durante o periodo de 32 a 67 semanas. A qualidade da casca dos ovos, mensurada por meio da gravidade especifica, melhorou com a suplementacao de 25(OH)D3 em reprodutoras com 60 semanas de idade, independentemente da dose. Nao foi observada diferenca significativa na taxa de eclosao de ovos ferteis incubados nas 54 e 64 semanas de idade das aves. As 64 semanas, houve menor mortalidade de embrioes na terceira semana entre as aves recebendo a dieta com 2.000 UI D3, enquanto, as 67 semanas, houve menor mortalidade na primeira semana de embrioes provenientes de reprodutoras sob suplementacao com 2.000 UI D3 e 2.000 UI D3 + 69 mg 25(OH)D3. A combinacao de 25-hidroxicolecalciferol e colecalciferol teve efeito similar ao das dietas com vitamina D3 como fonte exclusiva sobre o desempenho produtivo de reprodutoras pesadas.

Exploring the Relationship between Rumination, Self-compassion, and Mood

Self-compassion and rumination have been conceptualized as emotion regulation strategies, the former effective and the latter maladaptive, however, the relationship between these two approaches is largely unknown. This relationship was explored in 186 participants who completed a negative mood induction, and were randomly allocated to write about a negative event in either a self-compassionate or emotionally expressive way. Results showed that self-compassionate writing significantly predicted improved mood more so than writing in an emotionally expressive way. Greater rumination inhibited the degree to which mood improvements were made after writing, while trait self-compassion significantly predicted mood improvements. The present findings suggest that interventions to increase self-compassion can be therapeutically beneficial.
The Employment Policy for Aged Workers and the Finances of Unemployment Insurance

In the reform of the Japanese public pension system and unem- ployment insurance in 1995, a wage subsidy for aged workers funded by unem- ployment insurance was introduced. According to time series data, the wage elasticity of the labor demand for aged employees is elastic, whereas that of the labor supply is inelastic. Hence, the subsidy increases the demand for older work- ers by enabling fiirms to reduce their labor costs. At the same time, it raises the take-home pay of aged workers and improves their economic welfare. This fact is confirmed by the estimated results of the augmented demand system for aged workers. However, because unemployment insurance is financially dependent on the aging population, the contribution rates of unemployment insurance will rise in the near future.
A Procedure for Measuring and Validating a Construct of Service Innovation Capability Maturity

Service organisation success is not the result of discrete service innovations and should be attributed to the capability underpinning the repeated and continuous generation of these outputs, labelled service innovation capability (Poppelbus et al., 2011; Lillis et al., 2015; Nada and Ali, 2015; Hariandja, 2016). However, this capability is poorly understood and there is no mechanism available to organisations for evaluating their performance or identifying areas of strength or weakness (Hogan et al., 2011). This is a consequence of inadequate systematic effort devoted to methodological issues in this domain, where existing measures fail to follow established procedures in their development or measure the effectiveness, or maturity, of this capability (Tuominen and Anttila, 2006; Kohler et al., 2013). In response, this paper nominates a solution, describing comprehensive, best practice guidelines for the development and validation of a measure of the maturity of service innovation capability (MacKenzie et al., 2011).
Genetic Studies in Bread Wheat Under Irrigated and Drought Stress Conditions

A 6 × 6 diallel cross consisting of six wheat varieties/lines namely Pak 81, LU26S, Inqlab 91, Rohtas 90, 4072 and 4943 was analyzed to determine the nature of genetic mechanisms controlling some Morphophysiological traits, like stomatal frequency, leaf venation, flag leaf area, specific flag leaf weight, days to heading, tillers per plant, plant height, spike length, grains per spike, 1000-grain weight, biomass per plant and grain yield per plant under irrigated and drought stress conditions. Adequacy test satisfied the simple additive dominance model. High estimates of narrow sense heritability were found for stomata! frequency, specific flag leaf weight, days to heading, plant height, spike length and 1000-grain weight, also observed lower average degree of dominance under both environments. In the present study additive genetic effects were found to be more important than nonadditive effects with the exception of yield per plant which appeared to be more closely linked to nonadditive genetic effects. Since the yield components like grains per spike, 1000-grain weight, tillers per plant were found to be significantly influenced by additive gene action, further progress in genetic improvement of the yielding ability of wheat varieties may be attempted through such yield-related characters, with much better prospects of fixing desirable genes in a single homozygote.
ANALYSIS OF SCLERACTINIAN DISTRIBUTION IN TAIWAN INDICATING A PATTERN CONGRUENT WITH SEA SURFACE TEMPERATURES AND CURRENTS : EXAMPLES FROM ACROPORA AN D FAVIIDAE CORALS

Chaolun Allen Chen (1999) Analysis of scleractinian distribution in Taiwan indicating a pattern congruent with sea surface temperatures and currents: examples from Acropora and Faviidae corals. Zoological Studies 38(2): 119-129. Taiwan, a continental island with several offshore islets, is located on the center or junction of the Philippine-Japan island arc. Approximately 300 species of scleractinian corals occur around Taiwan and its neighboring islets except on the west coast with its sandy or muddy habitats. I analyzed the distribution patterns of 104 species of 2 major groups of scleractinian corals, the genus Acropora and family Faviidae, from 8 regional databases using distance and parsimony methods. Distance analyses (neighbor-joining) indicate that southern Taiwan and Green Island possess similar scleractinian distributions for both Acropora and Faviidae corals, whereas northeastern Taiwan groups with other locations of Penghu. Parsimony analysis (exhaustive search) of Acropora shows a similar pattern of distance analysis, whereas parsimonious tree of Faviidae united northeast- ern Taiwan with Green Island and South Taiwan leaving Penghu as a single group. Combining both Acropora and Faviidae, parsimony analysis suggests 2 distinct provinces of scleractinian distributions which show a congru- ence with sea surface temperatures and currents around Taiwan. Reef-building corals, the scleractinians, are distributed throughout tropical and subtropical re- gions of the world. Distribution patterns of sclerac- tinians are usually characterized in terms of numbers of families, genera, or species present in different regions. Veron (1995) summarized the global distri- bution and species diversity of scleractinians, sug- gesting that there is no Indo-Pacific center of diver- sity at the family level, with the Caribbean being almost as diverse as the Indo-Pacific. At the generic level, configuration of diversity is dominated by the Indo-Pacific center of diversity, with a relatively low diversity in the western Atlantic. Species diversity is also overwhelmingly high in the Indo-Pacific region with uniformity from the Red Sea to Fiji (Veron 1993 1995). Regional (or latitudinal) distribution of sclerac- tinians is presumably influenced by local physical- environmental constraints. Three major regions of the Indo-Pacific locations, including Philippines-
The roles of the RPD3 histone deacetylase in facilitating transcriptional responses to osmotic stress in S. cerevisiae

Modification of N-terminal histone tails is one of the major mechanisms by which chromatin state is modified to influence transcription, alongside DNA methylation. The most widely observed of the various histone modifications is acetylation, which is canonically known as a transcriptional up regulator. However, this view has been challenged by observations that RPD3, a widely-conserved histone deacetylase in S. cerevisiae, is required for full transcriptional induction during various stress responses in this organism. RPD3 forms 3 protein complexes in the cell known as Rpd3L, Rpd3S and Rpd3µ and it has not been defined in the literature which of these complexes mediates RPD3 action during the osmotic stress response. Furthermore, the mechanism by which RPD3 mediates transcriptional activation is undefined, with conflicting results in the literature. In this research, northern blotting analysis is carried out to analyse the transcriptional responses of strains carrying deletions in subunits of different RPD3 complexes to induction of osmotic stress via NaCl and sorbitol. Strains carrying deletions in Rpd3L subunits are found to be defective in the transcriptional response to osmotic stress, a result consistent with literature studies of other stress responses. ChIP-qPCR analysis is also carried out to analyse how histone acetylation is affected by osmotic stress, and how this is affected by loss of RPD3 and members of the different RPD3 complexes. Acetylation is found to increase at stress responsive loci after osmostress, alongside a depletion in total nucleosome occupancy. This is found to be decreased in strains carrying deletions in Rpd3L subunits, but not in strains carrying deletions in Rpd3S or Rpd3µ strains. Overall, the data support a conclusion that RPD3 mediates transcription via histone acetylation and nucleosome depletion at stress-responsive loci in response to osmotic stress, and that the Rpd3L complex is required for RPD3 action in this stress response.
Distinction of nektonic and benthic communities between fish-present (Salvelinus fontinalis) and natural fishless lakes

Natural geographic barriers and escarpments inhibited the post-glacial colonisation of numerous lakes by fish on the eastern Canadian Boreal Shield. The aim of this study was to assess how different top-down control in lakes containing a single fish population of brook trout (Salvelinus fontinalis) and naturally fishless lakes affects the characteristics and structure of littoral macroinvertebrate communities throughout the ice-free season. Nektonic and zoobenthic communities were examined through univariate community characteristics [abundance, species density, species richness (D), evenness (J'), diversity, N')] and multivariate species assemblages. The total abundance of nektonic and zoobenthic communities and their univariate diversity indices were similar between fish-present and fishless lakes over the entire sampling period. However, species assemblages for both types of macroinvertebrate communities were significantly different between fish-present and fishless lakes throughout the season. Typically, the same invertebrate species occurred in the two lake types; but their relative abundance was different. The results of our study show that the top-down control in fish-present and fishless lakes leads to different littoral community structures, which were not perceptible through the studied univariate community characteristics. This study highlights the importance of selecting appropriate indicators for the assessment of invertebrate communities in lakes of the eastern Canadian Boreal Shield.
Semantic context effects in language production: A swinging lexical network proposal and a review

The investigation of semantic context effects has served as a valuable tool in investigating mechanisms of language production. Classic semantic interference effects have provided influential support for and interest in a competitive lexical selection mechanism. However, recent interest in semantic facilitation effects has stimulated a discussion on whether context effects reflect competition during lexical selection. In this review we propose a framework of lexical selection by competition that is sensitive to the activation of lexical cohorts. We outline our proposal and then present a selective review of the empirical evidence, much of which has been central to the development of alternative non-competitive models. We suggest that by adopting the assumptions of our proposal we can parsimoniously account for a majority of the discussed semantic facilitation and interference effects.
On the diffuse soft X-ray emission from the nuclear region of M51

We present an analysis of the diffuse soft X-ray emission from the nuclear region of M51 combining both XMM-Newton RGS and Chandra data. Most of the RGS spectrum of M51 can be fitted with a thermal model with a temperature of ∼ 0.5 keV except for the O VII triplet, which is forbidden-line dominated. The Fe L-shell lines peak around the southern cloud, where the O VIII and N VII Lyα lines also peak. In contrast, the peak of the O VII forbidden line is about 10″ offset from that of the other lines, indicating that it is from a spatially distinct component. The spatial distribution of the O VII triplet mapped by the Chandra data shows that most of the O VII triplet flux is located at faint regions near edges, instead of the southern cloud where other lines peak. This distribution of the O VII triplet is inconsistent with the photoionization model. Other mechanisms that could produce the anomalous O VII triplet, including a recombining plasma and charge exchange X-ray emission, are discussed.
A Method for Estimating the Participation Rate of Elder Care

This paper focused on estimating the participation rate of care giving to elders. We used a theoretical model frame that was in common use for analyzing activity in the labor market and adjusted it for analyzing the care giving rate in elders. Using data of the rate of start taking care and the rate of end taking care in elders from the Survey of Health, Aging and Retirement in Europe we evaluated the rate of "caregivers" in whole population at age over 50 and among males, females, people in labor force and out of labor force. According to our results, the lowest care rate is among men 16.8%, and the highest is among females 18.88%, while for whole population at age over 50, the care rate is 18.2%. According to our findings, there is a very high end of care rate from treatment in all population groups, pointing to the existence of a very large substitution among caregivers, mainly among people not in labor force (76.2%).
Long-Term Properties of Interlaminar Shear Strength of Composite Laminates

Components made of fiber reinforced polymers (FRP) are frequently used in environments with fluctuating temperatures and moisture levels. These environmental factors lead to a degradation of the FRP in the long term. The mechanisms behind the degradation of FRPs and its effect on mechanical performance are not fully understood. For this reason, the main objective of this master thesis is to study how environmental factors, i.e. water and heat, affect the interlaminar shear strength (ILSS) of FRPs. This was achieved by conducting static and fatigue four-point flexural bending tests on I-beam shaped glass fiber/epoxy specimens. Both dry and conditioned specimens were tested. Conditioned specimens were immersed in a distilled water bath at 60°C for three months prior to testing. The tests were performed at temperatures of 40°C and 60°C. The obtained data was compared to data obtained at room temperature. An increase in test temperature led to a decrease in shear strength, shear modulus and yield strength and an increase in deflection at failure. This was also seen as a result of conditioning. An increase in test temperature led to a shorter fatigue life for the specimens. Conditioning showed similar effects. The degradation in mechanical performance should be considered when designing FRP components intended for use in harsh environments. The results obtained in this study can potentially be used in the development of models aiming to predict long-term properties of FRPs.
'The books don't talk to me!': Postgraduate student groups and research student identity formation

This paper explores alternative spaces for learning amongst postgraduate research (PGR) students in the form of research-related groups such as reading and discussion groups, writing groups, seminar series or social groups. Our research with PGR students and academics explores the pedagogy and role of such groups in student learning and identity formation. In this paper, we discuss our findings related to PGR student needs and the factors prompting the formation of research-related groups. A survey of 36 PGR students revealed that students were reasonably satisfied with the formal components of their research degrees such as supervision and mandatory units of study. Yet general dissatisfaction with other opportunities for intellectual engagement, and feelings of isolation, were also prevalent. We hypothesise that though a majority of students might feel supported to complete their higher research degree, they are not necessarily feeling supported in the transition to becoming scholars or in developing broader scholarly interests and networks. As other academic literature has opined, research-related student groups can fulfil a dual function, assisting students towards completion of their research degree but also socialising students into academia. This paper discusses the role that higher education institutions and faculties might play in supporting research-related groups. In particular, there is a balance to be achieved between facilitating groups and enabling sustainability while ensuring that PGR students maintain autonomy and a reciprocal degree of responsibility in governance of such groups, which are key to developing an academic identity.
Dim small target tracking based on improved particle filter

As to solve the problem of dim small target tracking in low signal-to-noise ratio (SNR<3 dB) scenes, an improved particle filter tracking method is proposed. This paper firstly obtains the gray feature by spatial position weighting method, and combines the neighborhood motion model and the gray probability graph to get the motion features of dim small target. Then construct the joint observation model of gray and motion features to calculate the particle weights. At the same time, in the process of tracking, the gray distribution of the target is not stable, and the strategy of adaptively updating the gray template of reference target is added. Finally, the sequence image is used to prove the tracking effect of dim small target. Experiments show that compared with the traditional particle filter algorithm, the proposed method greatly enhanced the tracking ability of dim small target in low SNR (SNR<3 dB) scenes.
Assessment of Cardiovascular Risks in Women and Current Preventive Approaches in Nursing

Incidence of diabetes and heart diseases among women is gradually increasing. Both diabetes and cardiovascular diseases usually show minimal symptoms until the development of complications. These symptoms are usually overlooked by women. Nurses have an important role in reducing the risk of these diseases. The aim of this review is to evaluate the effects of diabetes, metabolic syndrome, and female-specific risk factors of heart diseases in women, to overview the preventive health style changes and responsibilities of nurses in this field through emphasizing the importance of risk factors and risk estimation.
Detecting anthropogenic influence with a multi‐model ensemble

Averaging results from multiple models has previously been found to improve estimates of the climatology and seasonal predictions of atmospheric variables. Here we describe how a multi‐model mean of the simulated response to greenhouse gas and sulphate aerosol changes may be used to detect anthropogenic influence on surface temperature. The scaling factor on a combined greenhouse gas and sulphate aerosol response pattern is estimated using a five model ensemble, and is found to be similar to that estimated using individual models, with similar uncertainties. When applied to the simultaneous detection of separate greenhouse gas and sulphate aerosol responses, the multi‐model method indicates a closer consistency between the observations and simulated responses, with reduced uncertainties. This improvement is at least in part due to the larger ensemble sizes and increased length of control integration available when data from multiple models are combined.
