Effect of tolerance to Septoria tritici blotch on grain yield, yield components and grain quality in Argentinean wheat cultivars

Septoria tritici blotch (STB) caused by Zymoseptoria tritici (Mycosphaerella graminicola) is a major disease of wheat worldwide due to significant losses in grain yield and quality. Disease tolerance is the ability to maintain yield performance in the presence of disease symptoms. Therefore, it could be a useful tool in the management of the disease. Although it is known, that there is disease tolerance to STB in some wheat cultivars, this aspect has not been studied among Argentinean cultivars. The aims of this study were to evaluate genotypic differences in tolerance to STB among Argentinean cultivars, considering the relationship between the area under disease progress curve or the green leaf area or the non green leaf area duration with the grain yield. In addition the effect of the disease on yield, yield components, test weight, grain protein concentration, wet and dry gluten concentration and the influence of tolerance on these traits was investigated. Field experiments were carried out with ten cultivars in a split split plot design during 2010 and 2011. Inoculation treatments were the main plots and cultivars, the subplots. STB significantly reduced grain yield, their components, test weight and increase grain protein and gluten concentration. Cultivar Baguette 10 showed major tolerance to STB, indicated by a consistent low regression slope between the green area duration and yield, while Klein Chaja was non tolerant due to a high regression slope. However, many cultivars such as Buck Brasil, Buck 75 Aniversario, Klein Escorpion and Klein Flecha had considerably similar regression slopes to Baguette 10, provided good levels of tolerance. Other cultivars presented no significant differences. The correlation coefficient between tolerance and grain yield potential was not significant, suggesting that tolerant high yielding cultivars can be obtained. No relationship was found between quality group or tolerance with the increase in protein and gluten concentration due to STB either.
Shifting the Beveridge Curve What Affects Labor Market Matching?

This paper explores conditions and policies that could affect the matching between labor demand and supply. We identify shifts in the Beveridge curves for 12 OECD countries between 2000Q1 and 2013Q4 using three complementary methodologies and analyze the short run determinants of these shifts by means of limited dependent variable models. We find that labor force growth as well as employment protection legislation reduce the likelihood of an outward shift in the Beveridge curve, Our findings also show that the matching process is more difficult the higher the share of employees with intermediate levels of education in the labor force and when long term unemployment is more pronounced. Policies which could facilitate labor market matching include active labor market policies, such as incentives for start up and job sharing programs. Passive labor market policies, such as unemployment benefits, as well as labor taxation render matching signficantly more difficult.

Mirage Models Confront the LHC: III. Deflected Mirage Mediation

We complete the study of a class of string motivated effective supergravity theories in which modulus induced soft supersymmetry breaking is sufficiently suppressed in the observable sector so as to be competitive with anomaly mediated supersymmetry breaking. Here we consider deflected mirage mediation (DMM) where contributions from gauge mediation are added to those arising from gravity mediation and anomaly mediation. We update previous work that surveyed the rich parameter space of such theories, in light of data from the CERN Large Hadron Collider (LHC) and recent dark matter detection experiments. Constraints arising from LHC superpartner searches at \sqrt{s} 8\\rm TeV} are considered, and discovery prospects at \sqrt{s} 14\\rm TeV} are evaluated. We find that deflected mirage mediation generally allows for SU(3) charged superpartners of significantly lower mass (given current knowledge of the Higgs mass and neutralino relic density) than was found for the `pure' mirage mediation models of Kachru et al. Consequently, discovery prospects are enhanced for many combinations of matter multiplet modular weights. We examine the experimental challenges that will arise due to the prospect of highly compressed spectra in DMM, and the correlation between accessibility at the LHC and discovery prospects at large scale liquid xenon dark matter detectors.
Building a Private Cloud Computing and the analysis against DoS (Denial of Service) attacks: Case study at SMKN 6 Jakarta
Venue: 2016 4th International Conference on Cyber and IT Service Management

The development of Cloud Computing is growing and becoming a trend that is widely used in the world of telecommunications today. In education, cloud computing becomes something that is needed to support the teaching and learning process. We analyze and design the network infrastructure in schools to implement cloud computing in local area schools. Then we built a system to create a server for cloud computing that can be accessed through the wired network and wireless network. Once the server cloud computing is installed and then we test functions such as uploading and downloading files whether to run well. The next step is to perform the test by doing DOS (Denial Of Service) The results show when no server DoS attack goes well with a large throughput. However, after the DoS attacks decreased throughput value and the greater the number of attacks is increasingly reducing the throughput of the server cloud. This shows that Cloud Server that have been built are still vulnerable to DoS attacks.
Locality Aware Parallel Sparse Matrix Vector and Matrix Transpose Vector Multiplication on Many Core Processors
Venue: IEEE Transactions on Parallel and Distributed Systems

Sparse matrix vector and matrix transpose vector multiplication (SpMMTV) repeatedly performed as z ATx and y A z (or y A w) for the same sparse matrix A is a kernel operation widely used in various iterative solvers. One important optimization for serial SpMMTV is reusing A matrix nonzeros, which halves the memory bandwidth requirement. However, thread level parallelization of SpMMTV that reuses A matrix nonzeros necessitates concurrent writes to the same output vector entries. These concurrent writes can be handled in two ways: via atomic updates or thread local temporary output vectors that will undergo a reduction operation, both of which are not efficient or scalable on processors with many cores and complicated cache coherency protocols. In this work, we identify five quality criteria for efficient and scalable thread level parallelization of SpMMTV that utilizes one dimensional (1D) matrix partitioning. We also propose two locality aware 1D partitioning methods, which achieve reusing A matrix nonzeros and intermediate z vector entries; exploiting locality in accessing x y and z vector entries; and reducing the number of concurrent writes to the same output vector entries. These two methods utilize rowwise and columnwise singly bordered block diagonal (SB) forms of A. We evaluate the validity of our methods on a wide range of sparse matrices. Experiments on the 60 core cache coherent Intel Xeon Phi processor show the validity of the identified quality criteria and the validity of the proposed methods in practice. The results also show that the performance improvement from reusing A matrix nonzeros compensates for the overhead of concurrent writes through the proposed SB based methods.
Optimization of Block Sparse Matrix Vector Multiplication on Shared Memory Parallel Architectures
Venue: 2016 IEEE International Parallel and Distributed Processing Symposium Workshops (IPDPSW)

We examine the implementation of block compressed row storage (BCSR) sparse matrix vector multiplication (SpMV) for sparse matrices with dense block substructure, optimized for blocks with sizes from 2x2 to 32x32, on CPU, Intel many integrated core, and GPU architectures. Previous research on SpMV for matrices with dense block substructure has largely focused on the design of novel data structures to optimize performance for specific architectures or to store variable sized, variably aligned blocks, but depending on alternate storage formats breaks compatibility with existing preconditioners and solvers or imposes significant runtime costs when converting between matrix formats. This paper instead focuses on the optimization of SpMV using the standard block compressed row storage (BCSR) format. We give a set of algorithms that performs SpMV up to 4x faster than the NVIDIA cuSPARSE cusparseDbsrmv routine, up to 147x faster than the Intel Math Kernel Library (MKL) mkl dbsrmv routine (a single threaded BCSR SpMV kernel) and up to 3x faster than the MKL mkl dcsrmv routine (a multi threaded CSR SpMV kernel)
SIMD Parallel Sparse Matrix Vector and Transposed Matrix Vector Multiplication in DD Precision
Venue: VECPAR

We accelerate a double precision sparse matrix and DD vector multiplication (DD SpMV) and its transposition and DD vector multiplication (DD TSpMV) using SIMD AVX2. AVX2 requires changing the memory access pattern to allow four consecutive 64 bit elements to be read at once. In our previous research, DD SpMV in CRS using AVX2 needed non continuous memory load, processing for the remainder, and the summation of four elements in the AVX2 register. These factors degrade the performance of DD SpMV. In this paper, we compare the storage formats of DD SpMV and DD TSpMV for AVX2 to eliminate the performance degradation factors in CRS. Our result indicates that BCRS4x1, whose block size fits the AVX2 register's length, is effective for DD SpMV and DD TSpMV.
Lived experiences of student nurses caring for intellectually disabled people in a public psychiatric institution
Venue: Curationis

Caring for intellectually disabled people can be demanding for student nurses who are novices in the nursing profession. To ensure that quality nursing care is provided, student nurses should have an understanding of and a positive attitude towards intellectually disabled people. Nursing intellectually disabled people can be a challenge for the student nurses. Therefore, student nurses need to be able to deal with challenges of caring for intellectually disabled people.  This article aims to explore and describe experiences of student nurses caring for intellectually disabled people in a public psychiatric institution.  A qualitative, exploratory, descriptive and contextual research design was used. Data were collected through individual in depth phenomenological interviews, naive sketches and field notes. Thematic analysis was utilised to analyse the collected data. Results were contextualised within the literature and measures to ensure trustworthiness were adhered to. Ethical principals were also applied throughout the research process.  Five themes emerged from the data. Student nurses experienced a profoundly unsettling impact on their whole being when caring for intellectually disabled people; they developed a sense of compassion and a new way of looking at life, and experienced a need for certain physical, mental and spiritual needs to be met.  From the results, it is evident that student nurses were challenged in caring for intellectually disabled people. However, they developed a sense of awareness that intellectually disabled people have a need to be cared for like any other person.
Undergraduate nursing students' attitudes and use of research and evidence based practice an integrative literature review.
Venue: Journal of clinical nursing

This integrative review of the literature addresses undergraduate nursing students' attitudes towards and use of research and evidence based practice, and factors influencing this. Current use of research and evidence within practice, and the influences and perceptions of students in using these tools in the clinical setting are explored.  Evidence based practice is an increasingly critical aspect of quality health care delivery, with nurses requiring skills in sourcing relevant information to guide the care they provide. Yet, barriers to engaging in evidence based practice remain. To increase nurses' use of evidence based practice within healthcare settings, the concepts and skills required must be introduced early in their career. To date, however, there is little evidence to show if and how this inclusion makes a difference.  Integrative literature review.  ProQuest, Summon, Science Direct, Ovid, CIAP, Google scholar and SAGE databases were searched, and Snowball search strategies used. One hundred and eighty one articles were reviewed. Articles were then discarded for irrelevance. Nine articles discussed student attitudes and utilisation of research and evidence based practice.  Factors surrounding the attitudes and use of research and evidence based practice were identified, and included the students' capability beliefs, the students' attitudes, and the attitudes and support capabilities of wards/preceptors.  Undergraduate nursing students are generally positive toward using research for evidence based practice, but experience a lack of support and opportunity. These students face cultural and attitudinal disadvantage, and lack confidence to practice independently. Further research and collaboration between educational facilities and clinical settings may improve utilisation.  TO CLINICAL PRACTICE This paper adds further discussion to the topic from the perspective of and including influences surrounding undergraduate students and new graduate nurses.
Attitudes of Saudi nursing students toward nursing research

The role of research was supported by faculty, researchers and professional organizations as an essential standard for practice and professional accountability. It is important to equip students with a strong research foundation to facilitate judging applicability of findings to clinical settings, and conducting research and eventually improving the quality of health care. Increasing attention is directed to students' attitudes and involvement in research, however, no previous studies were located on the attitudes of Saudi students towards research.  To investigate the attitudes of nursing students toward research in Saudi Arabia.  A descriptive design with convenient sample of 244 senior students at a three campus college of nursing in three regions in Saudi Arabia using a 22 items self administered 4 point likert type attitude questionnaire.  Majority of students reported positive attitudes toward research with highest scores for 'usefulness of research' and 'personal interest in research' and lowest scores for 'using research in clinical practice' Research attitudes significantly correlated with students' seniority and having completed a research course.  Assessing students' attitudes towards research enhances implementation of findings in patient care and proposes means for developing positive attitudes and raising students' awareness of future role as practicing nurses. Students had positive attitudes toward research and its usefulness in professional work and less positive attitudes toward using research in practice. Faculty should develop students' knowledge and attitudes while studying at the college. Nursing and health related professions researchers should direct attention to promoting the ultimate implementation of evidence based practice by students as well as nurses
Combined atom probe tomography and density functional theory investigation of the Al off stoichiometry of k carbides in an austenitic Fe Mn Al C low density steel

We report on the investigation of the off stoichiometry and site occupancy of k carbide precipitates within an austenitic (g) Fe 29.8Mn 7.7Al 1.3C (wt. alloy using a combination of atom probe tomography and density functional theory. The chemical composition of the k carbides as measured by atom probe tomography indicates depletion of both interstitial C and substitutional Al, in comparison to the ideal stoichiometric L'12 bulk perovskite. In this work we demonstrate that both these effects are coupled. The off stoichiometric concentration of Al can, to a certain extent, be explained by strain caused by the k/g mismatch, which facilitates occupation of Al sites in k carbide by Mn atoms (MngAl anti site defects) The large anti site concentrations observed by our experiments, however, can only be stabilized if there are C vacancies in the vicinity of the anti site.
Least square optimization of pilot sequence length for massive MIMO systems
Venue: 2016 IEEE 21st International Workshop on Computer Aided Modelling and Design of Communication Links and Networks (CAMAD)

Pilot sequence length is a crucial parameter that has a significant impact on massive multiple input multiple output (MIMO) systems. In a massive MIMO radio cell, the base station (BS) estimates the channel from mutually orthogonal uplink pilot sequences to configure a receiver for the uplink and (assuming reciprocity) a precoder for the forward link. Reuse of pilot sequences in adjacent cells results in pilot contamination in massive MIMO systems. Having long pilot sequences would reduce pilot contamination at the expense of spectral efficiency and throughput while too short pilot sequence would affect the orthogonality and channel estimation. In this paper, we propose to optimize the pilot sequence length by applying the least square technique on the uplink channel using total pilot power as the constraint. Numerical results show the feasibility of this approach.
Public Employees and Performance Appraisal

There is considerable agreement that organizations can benefit from using performance appraisal. Nevertheless, some studies find that both supervisors and employees have negative reactions to the process. This article addresses this contradiction by emphasizing the importance of cognitive aspects of performance appraisal. Without understanding individual employees' reactions to performance appraisal and its supportive organizational context, it is less likely for performance appraisal to be used for its original objective, which is performance improvement. Given the importance of employee acceptance of a performance measurement system, this article attempts to identify key factors which can heighten employee acceptance of performance appraisal using data from the 2005 Merit Principles Survey. The findings indicate that the developmental use of performance appraisal, employee participation in performance standard setting, the quality of the relationship they have with their supervisors, and employee perceived empowerment are positively associated with employee acceptance of performance appraisal.
The Impacts of Performance Appraisal on Employees' Job Satisfaction and Organizational Commitment: A Case of Microfinance Institutions in Ghana

Performance appraisal is credited by researchers as a tool for spurring employees towards the attainment of organizational goals. Considering employees' attitudes as a vital component in the attainment of organizational goals, this study investigated the impacts of performance appraisal on the job satisfaction and commitment of employees. The study used a descriptive research design. A stratified random sampling was used to sample 200 respondents from Microfinance organizations in Ghana. The study used questionnaires as its data collection instrument.  Analysis and correlations were used to analyze the data collected. The study revealed that employees' job satisfaction is positively related to and impacted by fairness in the appraisal system, linking appraisals with promotion, clarity of roles and feedback about their performance. The study also revealed that employees' commitment is positively related to and impacted by the linkage of appraisals with salary, identification of training needs, clarity of performance appraisal purpose and employee involvement in the formulation of appraisal tools. The study recommends that organizations comply with rewards systems linked to performance levels, provide training to employees identified to be in need of training so as to further enhance the relevance of performance appraisal, and also instigate and/or maintain communication between management staff and their subordinates especially with regards to their performance.
Impact of Performance Appraisal Justice on the Effectiveness of Pay for Performance Systems After Civil Service Reform

The present study comprehensively examined how human resources (HR) directors in six U.S. state governments with drastic levels of civil service reform assess their states' pay for performance effectiveness in terms of the performance appraisal justice. It was found that the effectiveness of pay for performance is influenced by perceived fairness of performance appraisal. More specifically, this study found that perceived politicization of performance appraisal was negatively and significantly associated with pay for performance effectiveness. This study also found that perceived fairness of appraisal criteria was positively and significantly associated with pay for performance effectiveness. In addition, this study shows that the effectiveness of pay for performance may be affected by some demographic characteristics (e.g. age and gender) and state differences. In particular, drastic levels of civil service reform significantly and positively influenced the effectiveness of pay for performance, but insignificantly affected performance appraisal fairness. These results provide scholars and practitioners in the public sector with meaningful strategies for civil service reform.
Locus of Control and Performance Appraisal

This work contributes to the literature demonstrating an important role for psychological traits in labor market decisions. We show that West German workers with an internal locus of control sort into jobs with performance appraisals. Appraisals provide workers who believe they control their environment a tool to demonstrate their value and achieve their goals. We confirm that workers who are risk tolerant also sort into jobs with performance appraisals but explain why the influence of the locus of control and risk tolerance should not be additive. We demonstrate this by estimating a routinely large and significantly negative interaction in our sorting equations. We also show that important patterns of sorting are revealed only when taking into account the interaction of locus of control and risk tolerance.
of Krashen s Input Hypothesis Three Major Arguments

Second language acquisition (SLA) theories can be grouped into linguistic, psychological and sociocultural theories. Krashen's Monitor Model is seen as an innatist theory within the linguistic group. This paper critically reviews the Input Hypothesis, one of the five hypotheses of Krashen's Monitor Model. It examines three major arguments over the hypothesis, namely, the vagueness of the construct, the simplification of input, and the overclaims that he has made about the hypothesis.
