Sir William Osler suggested in 1899 that avocations (leisure activities) in doctors are related to an increased sense of vocation (professional engagement) and a decreased level of burnout. This study evaluated those claims in a large group of doctors practicing in the UK while taking into account a wide range of background variables. A follow-up questionnaire was sent to 4,457 UK-qualified doctors who had been included in four previous studies of medical school selection and training, beginning in 1980, 1985, 1990 and 1989/1991. A total of 2,845 (63.8%) doctors returned the questionnaire. Questions particularly asked about work engagement, satisfaction with medicine as a career, and personal achievement (Vocation/engagement), stress, emotional exhaustion, and depersonalization (BurnedOut), and 29 different leisure activities (Avocation/Leisure), as well as questions on personality, empathy, work experience, and demography. Doctors reporting more Avocation/Leisure activities tended to be women, to have older children, to be less surface-rational, more extravert, more open to experience, less agreeable, and to fantasize more. Doctors who were more BurnedOut tended to be men, to be more sleep-deprived, to report a greater workload and less choice and independence in their work, to have higher neuroticism, lower extraversion and lower agreeableness scores, and to have lower self-esteem. In contrast, doctors with a greater sense of Vocation/engagement, tended to see more patients, to have greater choice and independence at work, to have a deep approach to work, to have a more supportive-receptive work environment, to be more extravert and more conscientious, and to report greater self-esteem.Avocation/Leisure activities correlated significantly with Vocation/engagement, even after taking into account 25 background variables describing demography, work, and personality, whereas BurnedOut showed no significant correlation with Avocation/Leisure activities.

The literature data on chemiluminescence (CL) in cryogenic matrices have been classified and correlated for the first time. The role of studies on phosphorescence and CL at low temperatures in the development of cryochemistry is shown. The features of low-temperature CL in matrices of nitrogen and inert gases (fine structure of spectra, matrix effects) and the data on the mobility and reactivity of atoms and radicals at very low temperatures are examined. The trends in the development of studies on CL in cryogenic matrices, such as the search for systems involving polyatomic molecules and extending the forms of CL reactions, are followed. The reactions of active nitrogen with hydrocarbons that are accompanied by light emission and CL in the oxidation of carbenes at T >= 77 K are examined. The bibliography includes 112 references.

Few employment programmes exist to support forensic service users with severe mental health problems and a criminal history. Little is known about how best to achieve this. The Employment and Social Inclusion Project (ESIP) was developed and piloted to support forensic service users into employment and vocational activities. This pilot service evaluation aimed to assess the number of service users who secured employment/vocational activities and explored services users' and staff experiences. Quantitative data were collected to record the characteristics of participating service users and how many secured employment and engaged in vocational activities. Eighteen qualitative interviews were conducted with service users and staff. Fifty-seven service users engaged with the project, most were men (93.0%) and previously employed (82.5%). Four service users (7.0%) secured paid competitive employment. Eight (14.0%) gained other paid employment. Tailored one-to-one support to increase skills and build confidence was an important feature of the project. Creation of a painting and decorating programme offered training and paid/flexible work. This exploratory project achieved some success in assisting forensic service users into paid employment. Further research to identify what works well for this important group will be of great value.

The connection between vocational college education and vocational training is a new way for vocational colleges and enterprises to develop together. At present, vocational college education focusing on the education level of talent training, however, it ignores the needs of workers’ vocational training based on enterprise development planning and training of professional career development. Therefore, we should strengthen the connection between vocational training and vocational education. For the establishment of modern vocational education system, we should enhance the value of human capital of workers in order to adapt to the new economic norm with important practical signifi cance.

Commercial cinema is both narrative art and a widely-used mass medium that is built upon human stories. Among the contents of these stories there are many vocational aspects. Taking advantage of these circumstances we will proceed to analyze health vocations through eight films. Patch Adams allows us to approach the fulfillment of vocation, which has not been an easy task for women, as we can see in Allá en el setenta y tantos. Vocational fulfillment is at the core of the plot in The Citadel. Something the Lord Made is a good example to illustrate an unfulfilled vocation, in the same way as Awakenings and Arrowsmith represent the fulfillment of an unexpected vocation and a long pursued one. Finally, vocation can demand great sacrifices, which is made crystal clear in Korczak, and when vocation is not strictly followed it might lead to the greatest abominations, which is the case in "The Fugitive.

Full Text Available Circulant matrices have become a satisfactory tools in control methods for modern complex systems. In the paper, VanderLaan circulant type matrices are presented, which include VanderLaan circulant, left circulant, and g-circulant matrices. The nonsingularity of these special matrices is discussed by the surprising properties of VanderLaan numbers. The exact determinants of VanderLaan circulant type matrices are given by structuring transformation matrices, determinants of well-known tridiagonal matrices, and tridiagonal-like matrices. The explicit inverse matrices of these special matrices are obtained by structuring transformation matrices, inverses of known tridiagonal matrices, and quasi-tridiagonal matrices. Three kinds of norms and lower bound for the spread of VanderLaan circulant and left circulant matrix are given separately. And we gain the spectral norm of VanderLaan g-circulant matrix.

Two in vitro tests, one to detect bacterial mutagenicity (Ames test) on Salmonella typhimurium TA98, TA100, and TA1535 and the other the primary DNA damage (SOS Chromotest) on Escherichia coli PQ37, were applied to determine the overall genotoxic activity of 12 pesticides (azinphos methyl, chlorothalonil, chlorphyriphos ethyl, chlorphyriphos methyl, lambda-cyhalothrin, cypermethrin, cyprodinil, fenazaquin, fludioxonil, indoxacarb, iprodione and penconazol). These were detected by gas chromatography (GC) analysis with electron capture (ECD) and nitrogen phosphorus detection (NPD) in 18 samples of vegetables. Some extracts of vegetables, found positive for pesticides with GC, were subjected to the Ames test and SOS Chromotest to evaluate the possible antimutagenic and/or antigenotoxic effects of vegetable matrices. The same bioassays were also performed on the mixtures of pesticides found in these samples to evaluate whether interactions could occur between pesticides and be responsible for the possible antimutagenic and/or antigenotoxic effects of the contaminated matrices. Experiments were also carried out to compare the results found for contaminated vegetables with their content of antioxidant components. Significant differences in mutagenicity and genotoxicity were found among the pesticides selected for this study. Of the 12 pesticides tested, only azinphos methyl, cyprodinil, fludioxonil and iprodione were found to be positive for both S. typhimurium and E. coli. No mutagenic/genotoxic activity was found in the extracts of vegetables contaminated by pesticides. S. typhimurium TA1535 showed a strong positive mutagenic effect for the mixtures of pesticides while they were not able to induce the SOS system. The data concerning the content of polyphenols and the total reducing activity of the contaminated vegetables indicated high amounts of antioxidants that could explain the inhibitory effect on the activity of pesticides shown by vegetables.

Polycaprolactone (PCL) matrices were simultaneously loaded with the antiviral agents, tenofovir (TFV) and nevirapine (NVP), in combination to provide synergistic activity in the prevention of HIV transmission through the vaginal route. TFV and NVP were incorporated in PCL matrices at theoretical loadings of 10%TFV-10% NVP, 5%TFV-5%NVP and 5%TFV-10%NVP, measured with respect to the PCL content of the matrices. Actual TFV loadings ranged from 2.1% to 4.2% equating to loading efficiencies of about 41-42%. The actual loadings of NVP were around half those of TFV (1.2-1.9%), resulting in loading efficiencies ranging from 17.2% to 23.5%. Approximately 80% of the initial content of TFV was released from the PCL matrices into simulated vaginal fluid (SVF) over a period of 30 days, which was almost double the cumulative release of NVP (40-45%). The release kinetics of both antivirals over 30 days were found to be described most satisfactorily by the Higuchi model. In vitro assay of release media containing combinations of TFV and NVP released from PCL matrices confirmed a potential synergistic/additive effect of the released antivirals on HIV-1 infection of HeLa cells. These findings indicate that PCL matrices loaded with combinations of TFV and NVP provide an effective strategy for the sustained vaginal delivery of antivirals with synergistic/additive activity.

The purpose of this action research was to increase the mastery level of Form Five Social Science students in Tawau II National Secondary School in the operations of addition, subtraction and multiplication of matrices in Mathematics. A total of 30 students were involved. Preliminary findings through the analysis of pre-test results and questionnaire had identified the main problem faced in which the students felt confused with the application of principles of the operations of matrices when performing these operations. Therefore, an action research was conducted using an intervention programme called "G.P.S Matrices" to overcome the problem. This programme was divided into three phases. 'Gift of Matrices' phase aimed at forming matrix teaching aids. The second and third phases were 'Positioning the Elements of Matrices' and 'Strenghtening the Concept of Matrices'. These two phases were aimed at increasing the level of understanding and memory of the students towards the principles of matrix operations. Besides, this third phase was also aimed at creating an interesting learning environment. A comparison between the results of pre-test and post-test had shown a remarkable improvement in students' performances after implementing the programme. In addition, the analysis of interview findings also indicated a positive feedback on the changes in students' attitude, particularly in the aspect of students' understanding level. Moreover, the level of students' memory also increased following the use of the concrete matrix teaching aids created in phase one. Besides, teachers felt encouraging when conducive learning environment was created through students' presentation activity held in third phase. Furthermore, students were voluntarily involved in these student-centred activities. In conclusion, this research findings showed an increase in the mastery level of students in these three matrix operations and thus the objective of the research had been achieved.

Full Text Available The study analyses the historical development of vocational literacy in basic education and Non-Formal Vocational Education (NFVE in Mozambique, as well as current challenges and contradictions. The theoretical lens of Cultural-Historical Activity Theory (CHAT is employed in the study. Methodologically the study was executed through an analysis of oral, printed and e-resources produced by the main stakeholders and also the reflective experiences of the authors in their extensive educational work in the country. The findings reveal poorly developed vocational literacy education in schools and non-formal settings in spite of recurrent political declarations about its importance. There is a strong dependence by formal and particularly NFVE sectors on the technical and financial support provided by international organisations. Vocational literacy courses are characterized by a lack of adequate equipment and poor practice. As a consequence, theoretical or elementary forms of vocational knowledge are dominant in the courses, resulting in the dissatisfaction of both learners and educators. Vocational literacy development proved to be a complex field that faces many challenges and ischaracterised by diverse internal contradictions.

Introducing active learning pedagogy into a technical and vocational education and training academy in Kurdistan, Iraq

Science.gov (United States)

Dickson, Martina; Ladefoged, Svend Erik

2017-10-01

This article focuses on a teaching methodology project which investigated issues of teaching quality at a technical and vocational education and training (TVET) academy in Kurdistan, Northern Iraq. The academy was established in 2012 to provide unemployed youth with TVET, particularly workplace-relevant training. A needs analysis showed that the academy's teachers were mainly skilled in technical content areas rather than in pedagogy. Perhaps as a result, predominantly teacher-centred approaches to teaching were observed. However, teaching and learning in TVET, by its very definition, must consider active learning and practical training as core to its vocational purpose. Moreover, technical and pedagogical skills are intrinsically linked, since a teacher cannot effectively pass on technical skills without the necessary pedagogical skills to do so. It is on this premise that the authors of this article based their project, which was designed for the purpose of upgrading the teachers' pedagogical skills to incorporate more active learning strategies and practical work. Comparison of observation logs and feedback sessions at the conclusion of their project provided evidence that whilst some of the teachers' pedagogical skills had shifted towards using more dynamic teaching strategies, interviews strongly indicated that there was also some reluctance to incorporate active learning. In their conclusion, the authors suggest that the insights gained from this project could be further empirically examined in a larger, multi-institutional study.

An Analysis of the Lay Participation To Vocation Promotion in Vietnam

Directory of Open Access Journals (Sweden)

Full Text Available From the dawn of Vatican Council II, lay Catholics have been encouraged to actively participate to the life and mission of the Church. Many lay faithful have responded to this call and dispensed their service in various church ministries. However, many other lay men and wo men have not demonstrated a visible participation, especially in the mission of promoting priestly and religious vocations. In its attempt to advocate for a more active collaboration of Vietnamese lay people in vocation promotion, this paper will accomplis h three goals. It will stress once again that lay Christians in Vietnam need to share the responsibility entrusted to each by the Church in encouraging vocations. The paper then argues that lay presence in this ministry enhances its dynamic and effectivene ss. It finally explores ways lay faithful can employ to raise awareness in youth of the call to priesthood and religious life in their context and culture. As such, the study hopes to inspire all baptized to extend their participatory presence in vocation promotion with zeal and confidence.

PARENTAL INFLUENCE ON CREATIVITY DEVELOPMENT AND VOCATIONAL INTEREST OF CHILDREN IN EKITI STATE NIGERIA

Directory of Open Access Journals (Sweden)

Jonathan Ojo Oke

2015-08-01

Full Text Available Creativity is a natural endowment which can easily be displayed by children athome. Children are often seen playing with objects and drawings because of their natural quest and inward disposition to explore and come out with creative ideas or products. It is therefore imperative for parents to encourage and develop children at home to achieve this to greater heights. The aim of this study, therefore was to determine the influence of parents in development andvocational interest of children in Ekiti State, Nigeria. The study was carried outusing 400 Junior Secondary School students of age eleven to thirteen as samples. Specifically, the study sought to identify the types of creative activity the students normally engage in; their vocational interests and the influence their parents had in their creativity development and vocational interest. A Child-Creative Inventory Form (CCIF was used as an instrument for quantitative data collection. Data collected was analysed using both descriptive and inferential statistics. The findings of the study reveal that children in Ekiti State, Nigeria love to engage in creative activities mostly in technical and vocational skills, and that they are motivated by their parents to do so. The study also found that even though the students do engage in creative activities in vocational activities, yet their vocational interest is much more on other disciplines order than vocational subjects as influenced by their parents. It is therefore recommended that parents and teachers should encourage children whenever they are engaged in creative activities at home and in schools and help those to develop their career based on the children’s areas of interest.

Asymptotics of eigenvalues and eigenvectors of Toeplitz matrices

Böttcher, A.; Bogoya, J. M.; Grudsky, S. M.; Maximenko, E. A.

2017-11-01

Analysis of the asymptotic behaviour of the spectral characteristics of Toeplitz matrices as the dimension of the matrix tends to infinity has a history of over 100 years. For instance, quite a number of versions of Szegő's theorem on the asymptotic behaviour of eigenvalues and of the so-called strong Szegő theorem on the asymptotic behaviour of the determinants of Toeplitz matrices are known. Starting in the 1950s, the asymptotics of the maximum and minimum eigenvalues were actively investigated. However, investigation of the individual asymptotics of all the eigenvalues and eigenvectors of Toeplitz matrices started only quite recently: the first papers on this subject were published in 2009-2010. A survey of this new field is presented here. Bibliography: 55 titles.

Fungible Correlation Matrices: A Method for Generating Nonsingular, Singular, and Improper Correlation Matrices for Monte Carlo Research.

Science.gov (United States)

Waller, Niels G

2016-01-01

For a fixed set of standardized regression coefficients and a fixed coefficient of determination (R-squared), an infinite number of predictor correlation matrices will satisfy the implied quadratic form. I call such matrices fungible correlation matrices. In this article, I describe an algorithm for generating positive definite (PD), positive semidefinite (PSD), or indefinite (ID) fungible correlation matrices that have a random or fixed smallest eigenvalue. The underlying equations of this algorithm are reviewed from both algebraic and geometric perspectives. Two simulation studies illustrate that fungible correlation matrices can be profitably used in Monte Carlo research. The first study uses PD fungible correlation matrices to compare penalized regression algorithms. The second study uses ID fungible correlation matrices to compare matrix-smoothing algorithms. R code for generating fungible correlation matrices is presented in the supplemental materials.

Full Text Available This article deals with the problem of readiness for professional (educational activity of teachers in vocational schools. The paper determines the relevance of readiness of teachers of special subjects of vocational schools to personality-oriented professional interaction with students and singled pedagogical conditions that determine this process. The analysis of psychological and pedagogical literature on the interpretation of the concepts of "readiness" and "commitment to the professional (educational activities" is conducted. The features of this type of activity are revealed. It is determined that in the modern branch of science the phenomenon of readiness for professional work is studied at the personal, functional and personal-activity levels. The author suggests the generalized definition of "readiness for professional (teaching activity" in the context of personal interaction between the participants of the educational process of vocational school.

This discrepancy established approaches to the development of standards of employee’s vocational institutions and expenditures of staff, on the one hand, and the required planning spending on vocational education. When planning educational grants for training labor to local budgets is determined by the amount of expenditures that are relevant to the intergovernmental transfers, which include, in particular, spending on vocational education. Although the legislation stipulates the independence of local budgets and calculation of expenditures that are relevant to the intergovernmental transfers should be done only to determine the amount of educational grants for training labor, in practice there is a significant limitation of the autonomy of local governments in the planning of local budgets. Thus, the deterioration of the efficiency of spending on vocational education due to increasing labor costs and labor charges. The reason for this was the dynamics as increased wages and a change in the number of employees engaged in technical and vocational education. Value.

Double stochastic matrices in quantum mechanics

International Nuclear Information System (INIS)

Louck, J.D.

1997-01-01

The general set of doubly stochastic matrices of order n corresponding to ordinary nonrelativistic quantum mechanical transition probability matrices is given. Lande's discussion of the nonquantal origin of such matrices is noted. Several concrete examples are presented for elementary and composite angular momentum systems with the focus on the unitary symmetry associated with such systems in the spirit of the recent work of Bohr and Ulfbeck. Birkhoff's theorem on doubly stochastic matrices of order n is reformulated in a geometrical language suitable for application to the subset of quantum mechanical doubly stochastic matrices. Specifically, it is shown that the set of points on the unit sphere in cartesian n'-space is subjective with the set of doubly stochastic matrices of order n. The question is raised, but not answered, as to what is the subset of points of this unit sphere that correspond to the quantum mechanical transition probability matrices, and what is the symmetry group of this subset of matrices

Nyhan, L; Begley, M; Mutel, A; Qu, Y; Johnson, N; Callanan, M

2018-09-01

The aim of this study was to develop a model to predict growth of Listeria in complex food matrices as a function of pH, water activity and undissociated acetic and propionic acid concentration i.e. common food hurdles. Experimental growth curves of Listeria in food products and broth media were collected from ComBase, the literature and industry sources from which a bespoke secondary gamma model was constructed. Model performance was evaluated by comparing predictions to measured growth rates in growth media (BHI broth) and two adjusted food matrices (zucchini purée and béarnaise sauce). In general, observed growth rates were higher in broth than in the food matrices which resulted in the model over-estimating growth in the adjusted food matrices. In addition, model outputs were more accurate for conditions without acids, indicating that the organic acid component of the model was a source of inaccuracy. In summary, a new predictive growth model for innovating or renovating food products that rely on multi-hurdle technology was created. This study is the first to report on modelling of propionic acid as an inhibitor of Listeria in combination with other hurdles. Our findings provide valuable insights into predictive model design and performance and highlight the importance of experimental validation of models in real food matrices rather than laboratory media alone.

In compressed sensing, one takes samples of an N-dimensional vector using an matrix A, obtaining undersampled measurements . For random matrices with independent standard Gaussian entries, it is known that, when is k-sparse, there is a precisely determined phase transition: for a certain region in the (,)-phase diagram, convex optimization typically finds the sparsest solution, whereas outside that region, it typically fails. It has been shown empirically that the same property—with the same phase transition location—holds for a wide range of non-Gaussian random matrix ensembles. We report extensive experiments showing that the Gaussian phase transition also describes numerous deterministic matrices, including Spikes and Sines, Spikes and Noiselets, Paley Frames, Delsarte-Goethals Frames, Chirp Sensing Matrices, and Grassmannian Frames. Namely, for each of these deterministic matrices in turn, for a typical k-sparse object, we observe that convex optimization is successful over a region of the phase diagram that coincides with the region known for Gaussian random matrices. Our experiments considered coefficients constrained to for four different sets , and the results establish our finding for each of the four associated phase transitions. PMID:23277588

This work investigated the feasibility and effectiveness of MSWI fly ash-based Friedel matrices on stabilizing/solidifying industrial chromium-bearing electroplating sludge using MSWI fly ash as the main raw material with a small addition of active aluminum. The compressive strength, leaching behavior and chemical speciation of heavy metals and hydration phases of matrices were characterized by TCLP, XRD, FTIR and other experimental methods. The results revealed that MSWI fly ash-based Friedel matrices could effectively stabilize chromium-bearing electroplating sludge, the formed ettringite and Friedel phases played a significant role in the fixation of heavy metals in electroplating sludge. The co-disposal of chromium-bearing electroplating sludge and MSWI fly ash-based Friedel matrices with a small addition of active aluminum is promising to be an effective way of stabilizing chromium-bearing electroplating sludge.

Vocational rehabilitation: a multidisciplinary intervention.

Science.gov (United States)

Gobelet, C; Luthi, F; Al-Khodairy, A T; Chamberlain, M A

2007-09-15

Vocational rehabilitation is by definition a multidisciplinary intervention in a process linked to the facilitation of return to work or to the prevention of loss of the work. Clinical staff in contact with a person who has lost his job (general practitioner, specialized physician) must promote vocational rehabilitation. Medical rehabilitation for those with disabilities, whether new or old, has to be followed without delay by vocational rehabilitation. It is even better if these two intertwined processes are overlapping. They involve many professionals including physiotherapists, occupational therapists, psychologists, vocational trainers, job counsellors, teachers, case-managers, job placement agencies. Vocational rehabilitation has a financial cost, borne by many state organizations (security, social system, social affairs) as well as by employers and private insurances, which are in case of accident, concerned by this process. However, the evidence suggests that this is recouped 2- to 10-fold as suggested by the British Society of Rehabilitation Medicine.

Vocational guidance in social volunteering

Directory of Open Access Journals (Sweden)

Nikolay S. Pryazhnikov

2017-03-01

Full Text Available The paper discusses the possibilities and limitations of vocational guidance in the social volunteering system. The essence of volunteer work is closely related with assistance to desperate people in searching for the meaning of living, often coinciding with labour activity that are deemed in terms of “the main matter of life” and “the leading activity”. For adolescents, it is the choice of career, and for adults, it is the work proper (i.e. an essential condition for personal self-realization. The problem of “forced volunteering” for experts in vocational guidance also means that they often have to work voluntarily and unselfishly outside the official guidelines. To clarify the terms «volunteer» and «a person in desperate need of help» the study used the method of analyzing the documents, e.g. the Regulations on Social Volunteering, the generalization of psychological sources, the initial survey of university students as active supporters of the volunteer movement, On the essence of volunteering and the place of career guidance in selfless social work. Vocational guidance is not excluded from the general system of volunteerism, but has an insufficiently defined status and low popularity among participants in social volunteering. Also, the problem of «forced volunteering» of experts in career counseling, which often requires voluntary and unselfish performance of quality work outside the framework of official instructions, is also indicated. Simultaneously, positive aspects of such disinterested career initiatives are noted, in particular, less control by the official inspectors (or customers and, accordingly, greater freedom of creativity than when someone else does the work.

Manin matrices and Talalaev's formula

International Nuclear Information System (INIS)

Chervov, A; Falqui, G

2008-01-01

In this paper we study properties of Lax and transfer matrices associated with quantum integrable systems. Our point of view stems from the fact that their elements satisfy special commutation properties, considered by Yu I Manin some 20 years ago at the beginning of quantum group theory. These are the commutation properties of matrix elements of linear homomorphisms between polynomial rings; more explicitly these read: (1) elements of the same column commute; (2) commutators of the cross terms are equal: [M ij , M kl ] [M kj , M il ] (e.g. [M 11 , M 22 ] = [M 21 , M 12 ]). The main aim of this paper is twofold: on the one hand we observe and prove that such matrices (which we call Manin matrices in short) behave almost as well as matrices with commutative elements. Namely, the theorems of linear algebra (e.g., a natural definition of the determinant, the Cayley-Hamilton theorem, the Newton identities and so on and so forth) have a straightforward counterpart in the case of Manin matrices. On the other hand, we remark that such matrices are somewhat ubiquitous in the theory of quantum integrability. For instance, Manin matrices (and their q-analogs) include matrices satisfying the Yang-Baxter relation 'RTT=TTR' and the so-called Cartier-Foata matrices. Also, they enter Talalaev's remarkable formulae: det(∂ z -L gaudin (z)), det(1-e -∂z T Yangian (z)) for the 'quantum spectral curve', and appear in the separation of variables problem and Capelli identities. We show that theorems of linear algebra, after being established for such matrices, have various applications to quantum integrable systems and Lie algebras, e.g. in the construction of new generators in Z(U crit (gl-hat n )) (and, in general, in the construction of quantum conservation laws), in the Knizhnik-Zamolodchikov equation, and in the problem of Wick ordering. We propose, in the appendix, a construction of quantum separated variables for the XXX-Heisenberg system

Today, the importance of training qualified individuals which holds an important place in the development of countries increases and certain standards are adopted creating common European Union tools in the field of vocational and technical education. In this study, vocational education and training policies system and the standards adopted by the European Union are discussed. Furthermore, this study was accepted as a European Union project in 2010 and the results obtained from the Leonardo Da Vinci Life Learning European Union project called “Web Based Basic Vocational Training” between the years 2010-2012 were presented. Since the partners of these projects are Turkey, Spain and Germany, the structure of vocational education, institutions of public and private vocational education and the diplomas and certificates entitled after these educations are included. As Turkey is on its way to become a European Union member, a number of advices are presented for Turkey to reach its destination about vocational education standards that European Union has aimed. The purpose of the study is not only to be a guide for the young who want to get professional training in the countries that are European Union members or candidates about how and where to have education opportunities but also to give a chance for trainers and training managers, participating in vocational training, so as to glimpse different practices from different countries and compare these practices between the countries of European Union and their countries. The study is also very important as it has the opportunities for training managers to see if their countries' vocational education is close enough to vocational education in European Union.

2014-05-01

Full Text Available Purpose. The paper deals with the problem of basic generalizations of Hadamard matrices associated with maximum determinant matrices or not optimal by determinant matrices with orthogonal columns (weighing matrices, Mersenne and Euler matrices, ets.; calculation methods for the quasi-orthogonal local maximum determinant Mersenne matrices are not studied enough sufficiently. The goal of this paper is to develop the theory of Mersenne and Hadamard matrices on the base of generalized Scarpis method research. Methods. Extreme solutions are found in general by minimization of maximum for absolute values of the elements of studied matrices followed by their subsequent classification according to the quantity of levels and their values depending on orders. Less universal but more effective methods are based on structural invariants of quasi-orthogonal matrices (Silvester, Paley, Scarpis methods, ets.. Results. Generalizations of Hadamard and Belevitch matrices as a family of quasi-orthogonal matrices of odd orders are observed; they include, in particular, two-level Mersenne matrices. Definitions of section and layer on the set of generalized matrices are proposed. Calculation algorithms for matrices of adjacent layers and sections by matrices of lower orders are described. Approximation examples of the Belevitch matrix structures up to 22-nd critical order by Mersenne matrix of the third order are given. New formulation of the modified Scarpis method to approximate Hadamard matrices of high orders by lower order Mersenne matrices is proposed. Williamson method is described by example of one modular level matrices approximation by matrices with a small number of levels. Practical relevance. The efficiency of developing direction for the band-pass filters creation is justified. Algorithms for Mersenne matrices design by Scarpis method are used in developing software of the research program complex. Mersenne filters are based on the suboptimal by

[Career consciousness among Japanese female students: relationships between vocational motivation and career exploration].

Science.gov (United States)

Adachi, Tomoko

2008-04-01

This questionnaire study investigated career consciousness among 348 Japanese female freshman and sophomore college students. Variables included career consciousness (belief in the idea of a best-fit vocation, passivity, and giving priority to personal interests), vocational motives (self-improvement, interpersonal, status), as well as career decision-making self-efficacy (self-appraisal, gathering occupational information) and career exploration (self and environmental exploration). The results of causal analyses showed that the belief in the idea of a best-fit vocation and passivity had effects on all three vocational motives, but giving priority to personal interests had an effect only on motivation for self-improvement. Analysis of covariance (ANCOVA) models were constructed with career exploration as dependent variables, career consciousness as fixed factors, and career decision-making self-efficacy as covariates. The results of the analyses showed that students who had high career decision-making self-efficacy engaged in both self exploration and environmental exploration activities with a higher frequency. Students with a greater passive tendency toward their career engaged in both self and environmental exploration with a lower frequency. Belief in the idea of a best-fit vocation was associated only with differences in frequency of self exploration. Giving priority to personal interests did not produce differences in career exploration activities.

Two germs of linear analytic differential systems x k + 1Y‧ = A (x) Y with a non-resonant irregular singularity are analytically equivalent if and only if they have the same eigenvalues and equivalent collections of Stokes matrices. The Stokes matrices are the transition matrices between sectors on which the system is analytically equivalent to its formal normal form. Each sector contains exactly one separating ray for each pair of eigenvalues. A rotation in S allows supposing that R+ lies in the intersection of two sectors. Reordering of the coordinates of Y allows ordering the real parts of the eigenvalues, thus yielding triangular Stokes matrices. However, the choice of the rotation in x is not canonical. In this paper we establish how the collection of Stokes matrices depends on this rotation, and hence on a chosen order of the projection of the eigenvalues on a line through the origin.

Hierarchical matrices algorithms and analysis

CERN Document Server

Hackbusch, Wolfgang

2015-01-01

This self-contained monograph presents matrix algorithms and their analysis. The new technique enables not only the solution of linear systems but also the approximation of matrix functions, e.g., the matrix exponential. Other applications include the solution of matrix equations, e.g., the Lyapunov or Riccati equation. The required mathematical background can be found in the appendix. The numerical treatment of fully populated large-scale matrices is usually rather costly. However, the technique of hierarchical matrices makes it possible to store matrices and to perform matrix operations approximately with almost linear cost and a controllable degree of approximation error. For important classes of matrices, the computational cost increases only logarithmically with the approximation error. The operations provided include the matrix inversion and LU decomposition. Since large-scale linear algebra problems are standard in scientific computing, the subject of hierarchical matrices is of interest to scientists ...

This book expounds three special kinds of matrices that are of physical interest, centering on physical examples. Stochastic matrices describe dynamical systems of many different types, involving (or not) phenomena like transience, dissipation, ergodicity, nonequilibrium, and hypersensitivity to initial conditions. The main characteristic is growth by agglomeration, as in glass formation. Circulants are the building blocks of elementary Fourier analysis and provide a natural gateway to quantum mechanics and noncommutative geometry.

This study examined the outcomes of a vocational rehabilitation program (The Job Management Program, JUMP) for persons with psychotic disorders based on close collaboration between health and welfare services. Participants (N = 148) with broad schizophrenia spectrum disorders (age 18-65) were recruited from six counties in Norway. Three counties were randomized to vocational rehabilitation augmented with cognitive behaviour therapy (CBT), while the remaining three counties were randomized to vocational rehabilitation augmented with cognitive remediation (CR). This paper compares the vocational activity of the total group of JUMP participants with a treatment as usual group (N = 341), and further examines differences between the two JUMP interventions. Employment status (working/not working) was registered at the time of inclusion and at the end of the intervention period. The total number of JUMP participants in any kind of vocational activity increased from 17 to 77% during the intervention. Of these, 8% had competitive employment, 36% had work placements in ordinary workplaces with social security benefits as their income, and 33% had sheltered work. The total number of working participants in the TAU group increased from 15.5 to 18.2%. The JUMP group showed significant improvements of positive (t = -2.33, p = 0.02) and general (t = -2.75, p = 0.007) symptoms of psychosis. Significant differences between the CBT and CR interventions were not demonstrated. The study supports existing evidence that the majority of persons with broad schizophrenia spectrum disorders can cope with some kind of work, given that internal and external barriers are reduced. Those who wish to work should be offered vocational rehabilitation. ClinicalTrials.gov Identifier: NCT01139502 . Registered on 6 February 2010.

2012-01-01

Full Text Available The paper explores the concept of vocational educational environment combining vocational training, professional development and professional world. The research is aimed at the self-determination analysis of an individual in the above environment. The authors observe the two existing trends of self-development analysis, corresponding with the subjective activity and culturally historical approaches. The empirical research results involve the students’ subjective individual characteristics and factors influencing the self-development strategy selection. The research findings prove the earlier hypothesis of the self- development phenomenon being determined by the two mutually conditioned factors: personal self-control ability and interrelation of the above mentioned components of the vocational educational environment. The authors make the conclusion that the self-development prospects are determined by the internal and external motivation, professional mobility and striving for success. The determination specificity of professional self- development, identified by the authors, can provide the psychological basis for future specialists training.

Frequency filtering decompositions for unsymmetric matrices and matrices with strongly varying coefficients

Energy Technology Data Exchange (ETDEWEB)

Wagner, C.

1996-12-31

In 1992, Wittum introduced the frequency filtering decompositions (FFD), which yield a fast method for the iterative solution of large systems of linear equations. Based on this method, the tangential frequency filtering decompositions (TFFD) have been developed. The TFFD allow the robust and efficient treatment of matrices with strongly varying coefficients. The existence and the convergence of the TFFD can be shown for symmetric and positive definite matrices. For a large class of matrices, it is possible to prove that the convergence rate of the TFFD and of the FFD is independent of the number of unknowns. For both methods, schemes for the construction of frequency filtering decompositions for unsymmetric matrices have been developed. Since, in contrast to Wittums`s FFD, the TFFD needs only one test vector, an adaptive test vector can be used. The TFFD with respect to the adaptive test vector can be combined with other iterative methods, e.g. multi-grid methods, in order to improve the robustness of these methods. The frequency filtering decompositions have been successfully applied to the problem of the decontamination of a heterogeneous porous medium by flushing.

The European Dimensions of Vocational Training

Directory of Open Access Journals (Sweden)

Sós Tamás

2015-12-01

Full Text Available The research examined the connection between vocational education, training and the world of work, and the social situation in Hungary in a European outlook. The accentual issues of the analysis disclosing the problem are: youth unemployment, the tendencies of secondary vocational education, proportions of enrollment and the features of training tendencies, the growing number of early dropouts, the effect of family background on student performance. This work tried to find the answer to the question: What variations have the changes in the regulations of vocational training, encouraging dual education brought on in the connection between trainers and work places? The research did not prove that the central vocational training system would be more effective than a varied, flexible, permeable, transparent decentralized operation with parts built on each other. The introduction of the complex exam overshadowed the evaluation of the competency areas, and fits less to the modularity of the framework curricula. With the legal regulation of vocational training in force the modular system has become a formality. Taking prior knowledge into account has become more difficult. The efficiency of professional structural decisions is questionable, it has not triggered the extension of employment among career starters, and does not mean a guarantee of finding a job either. Creating the motivation of economic role players may bring on steps forward to take up bigger tasks in vocational training. The research has confirmed the importance of improving the basic competency areas when planning vocational training, of life-long learning, of practice orientation, and also of the continuous connection with the labor market.

Full Text Available The aim of this research is to explore the prospect of teaching Entrepreneurship Education to those who acquire vocational skills at Punjab Vocational Training Council (PVTC. It is also to explore whether PVTC has promoted entrepreneurship through its vocational training institutes located all over Punjab. This study also deals with the concept of utilization of ‘Zakat' for the purpose of vocational education as a mode for possible replication. The research objective has been to follow the progress of this institution. It has also been to record the successes of this model of a public-private ownership, a model of utilizing the ‘Zakat' to fund education projects, a value based organization, a learning organization and a highly innovative institution. The other objective is to explore the evidence of entrepreneurship education and its effectiveness in PVTC. Literature has been reviewed on vocational training and entrepreneurship education. It also reviews experience and evidence of such practice prevailing in other environment. Combined with this is the review and conceptualization of a model based on ‘zakat'. Research Methodology used is basically qualitative; data has been collected through semi structured intensive interviews and from focus groups of stakeholders. The strategies adopted to collect data in this study are “survey”, “case study” and “grounded theory.” The data collected from semi structured interviews were concluded by thematic analysis, analyzing technique of writing reports from data. NVivo software was utilized for triangulation to reduce the data bias and increase validity by comparing primary and secondary data. The findings of this research have been that the pedagogical skills offered by PVTC's are not effective for entrepreneurial potential development.

Pathological rate matrices: from primates to pathogens

Directory of Open Access Journals (Sweden)

Knight Rob

2008-12-01

Full Text Available Abstract Background Continuous-time Markov models allow flexible, parametrically succinct descriptions of sequence divergence. Non-reversible forms of these models are more biologically realistic but are challenging to develop. The instantaneous rate matrices defined for these models are typically transformed into substitution probability matrices using a matrix exponentiation algorithm that employs eigendecomposition, but this algorithm has characteristic vulnerabilities that lead to significant errors when a rate matrix possesses certain 'pathological' properties. Here we tested whether pathological rate matrices exist in nature, and consider the suitability of different algorithms to their computation. Results We used concatenated protein coding gene alignments from microbial genomes, primate genomes and independent intron alignments from primate genomes. The Taylor series expansion and eigendecomposition matrix exponentiation algorithms were compared to the less widely employed, but more robust, Padé with scaling and squaring algorithm for nucleotide, dinucleotide, codon and trinucleotide rate matrices. Pathological dinucleotide and trinucleotide matrices were evident in the microbial data set, affecting the eigendecomposition and Taylor algorithms respectively. Even using a conservative estimate of matrix error (occurrence of an invalid probability, both Taylor and eigendecomposition algorithms exhibited substantial error rates: ~100% of all exonic trinucleotide matrices were pathological to the Taylor algorithm while ~10% of codon positions 1 and 2 dinucleotide matrices and intronic trinucleotide matrices, and ~30% of codon matrices were pathological to eigendecomposition. The majority of Taylor algorithm errors derived from occurrence of multiple unobserved states. A small number of negative probabilities were detected from the Pad�� algorithm on trinucleotide matrices that were attributable to machine precision. Although the Pad

Restrictions and Countermeasures of Rural Vocational Education in Urban-rural Integration

Developing rural vocational education is of great significance to urban-rural integration: developing rural vocational education is helpful to cultivating new farmers for construction of new socialist countryside,favorable to improving farmers’ ability of finding jobs and starting undertaking, and beneficial to transfer of rural surplus labor and acceleration of urbanization. Restrictions on development rural vocational education mainly include: low value cognition of society and social assessment of rural vocational education; out of balance of cost and expected return of rural vocational education; the quality of supply of rural vocational education failure to satisfy demand of socio-economic development; imperfect rural vocational education system. In view of these,following countermeasures and suggestions are put forward: strengthen propaganda and guidance to build environment of public opinion for rural vocational education; push forward rural vocational compulsory education system to lay social foundation for rural vocational education; reinforce policy support to assist in building rural vocational education system; improve education system to build overall framework of rural vocational education; perfect laws and regulations to establish system and norm for development of rural vocational education.

Spectra of sparse random matrices

International Nuclear Information System (INIS)

Kuehn, Reimer

2008-01-01

We compute the spectral density for ensembles of sparse symmetric random matrices using replica. Our formulation of the replica-symmetric ansatz shares the symmetries of that suggested in a seminal paper by Rodgers and Bray (symmetry with respect to permutation of replica and rotation symmetry in the space of replica), but uses a different representation in terms of superpositions of Gaussians. It gives rise to a pair of integral equations which can be solved by a stochastic population-dynamics algorithm. Remarkably our representation allows us to identify pure-point contributions to the spectral density related to the existence of normalizable eigenstates. Our approach is not restricted to matrices defined on graphs with Poissonian degree distribution. Matrices defined on regular random graphs or on scale-free graphs, are easily handled. We also look at matrices with row constraints such as discrete graph Laplacians. Our approach naturally allows us to unfold the total density of states into contributions coming from vertices of different local coordinations and an example of such an unfolding is presented. Our results are well corroborated by numerical diagonalization studies of large finite random matrices

Strategies for Translating Vocative Texts

Directory of Open Access Journals (Sweden)

Olga COJOCARU

2014-12-01

Full Text Available The paper deals with the linguistic and cultural elements of vocative texts and the techniques used in translating them by giving some examples of texts that are typically vocative (i.e. advertisements and instructions for use. Semantic and communicative strategies are popular in translation studies and each of them has its own advantages and disadvantages in translating vocative texts. The advantage of semantic translation is that it takes more account of the aesthetic value of the SL text, while communicative translation attempts to render the exact contextual meaning of the original text in such a way that both content and language are readily acceptable and comprehensible to the readership. Focus is laid on the strategies used in translating vocative texts, strategies that highlight and introduce a cultural context to the target audience, in order to achieve their overall purpose, that is to sell or persuade the reader to behave in a certain way. Thus, in order to do that, a number of advertisements from the field of cosmetics industry and electronic gadgets were selected for analysis. The aim is to gather insights into vocative text translation and to create new perspectives on this field of research, now considered a process of innovation and diversion, especially in areas as important as economy and marketing.

Schroeder, David H; Haier, Richard J; Tang, Cheuk Ying

2012-05-16

Previous studies have identified brain areas related to cognitive abilities and personality, respectively. In this exploratory study, we extend the application of modern neuroimaging techniques to another area of individual differences, vocational interests, and relate the results to an earlier study of cognitive abilities salient for vocations. First, we examined the psychometric relationships between vocational interests and abilities in a large sample. The primary relationships between those domains were between Investigative (scientific) interests and general intelligence and between Realistic ("blue-collar") interests and spatial ability. Then, using MRI and voxel-based morphometry, we investigated the relationships between regional gray matter volume and vocational interests. Specific clusters of gray matter were found to be correlated with Investigative and Realistic interests. Overlap analyses indicated some common brain areas between the correlates of Investigative interests and general intelligence and between the correlates of Realistic interests and spatial ability. Two of six vocational-interest scales show substantial relationships with regional gray matter volume. The overlap between the brain correlates of these scales and cognitive-ability factors suggest there are relationships between individual differences in brain structure and vocations.

Following Hermann Weyl's classical approach, the ring of invariants is described by formulating and proving the first fundamental theorem that describes a set of generators in the ring of invariants, and the second fundamental theorem that describes relations between these generators. The authors study both the case of matrices over a field of characteristic 0 and the case of matrices over a field of positive characteristic. While the case of characteristic 0 can be treated following a classical approach, the case of positive characteristic (developed by Donkin and Zubkov) is much harder. A presentation of this case...

Vocational Teaching-Learning through the Eyes of Undergraduate Vocational Students in Malta: A Qualitative Exploratory Study

Full Text Available The purpose of this study is to develop a deeper understanding of the teaching qualities of effective lecturers that vocational students desire, students assessment preferences and preferred learning environments. This study gives a voice to higher vocational students as it is important for vocational educators to learn what attracts students to effective learning. Due to the inquiry’s exploratory nature, an interpretivist approach was used, and a constructivist grounded approach using qualitative data was adopted. A purposive approach to multiple case study selection was used where the unit of analysis was a higher vocational student. The perceptions and expectations of vocational undergraduate (EQF level 6 students in two disciplines (applied science and engineering were explored, to identify what may constitute good practice. A total of ten participants from two different institutes within the vocational university college agreed to be interviewed. Semi-structured and photo-elicitation interviews were applied. In addition, the Powerful Learning Environments (PLEs Framework was used as a preliminary tool to aid in the decision-making process for data collection. Iterative analysis was used for the semi- structured interviews, whilst a constant-comparative method was used for the photo- elicitation image analysis. Overall, the expectations and preferences between both groups were very similar. Results show that students expect to be taught by interactive lectures that relate theory to practice that will prepare them for the job. Formal lectures including presentations were the least favoured. Regarding teaching qualities, students expect approachable and understanding lecturers who provide concrete industrial examples. Assessment preferences included home based assignments and research projects. The preferred learning environment is in line with most characteristics of the Powerful Learning Environment. Evidence shows that there is no

This document provides the status of the preliminary hazard classification (PHC) process for the Environmental Restoration Contractor (ERC) above ground structures and groundwater and soil remediation activities currently underway for planned for fiscal year (FY) 1997. This classification process is based on current US Department of Energy (DOE), Richland Operations Office (RL) guidance for the classification of facilities and activities containing radionuclide and nonradiological hazardous material inventories. The above ground structures presented in the matrices were drawn from the Bechtel Hanford, Inc. (BHI) Decontamination and Decommissioning (D and D) Project Facility List (DOE 1996), which identifies the facilities in the RL-Environmental Restoration baseline contract in 1997. This document contains the following two appendices: (1) Appendix A, which consists of a matrix identifying PHC documents that have been issued for BHI's above ground structures and groundwater and soil remediation activities underway or planned for FY 1997, and (2) Appendix B, which consists of a matrix showing anticipated PHCs for above ground structures, and groundwater and soil remediation activities underway or planned for FY 1997. Appendix B also shows the schedule for finalization of PHCs for above ground structures with an anticipated classification of Nuclear

Exhaustion is consistently found to be more prevalent in women than in men. Women suffer from job strain more often, which may constitute a partial explanation for this phenomenon, but experienced shortcomings in combining work and family demands may also contribute to ill health. The aim of this study was to investigate, and analyse by gender, how work-related and family-related factors, as well as the interface between them, i.e. work-to-family conflict (WFC) and family-to-work conflict (FWC), are related to exhaustion. The study was cross-sectional with self-administered questionnaires assessing exposures and outcome with previously well-validated instruments. The participants were 2726 men and 2735 women, aged 45-64, vocationally active, and residing in Malmö, Sweden. Sixteen percent of the women and 8% of the men considered themselves exhausted. WFC, FWC, job strain, and low job support were all strongly correlated to exhaustion in both genders. In the multivariate analyses, adjusting for other work and family risk factors, WFC and FWC remained statistically significant risk factors for exhaustion in both men and women. Job strain, low job support, and having a somatic disorder were also independently associated with exhaustion. While WFC was more prevalent among men, it was more strongly associated with exhaustion in women than in men. In women, WFC and FWC contributed to a larger part of the explanatory power of the model, which amounted to 22% of the variance in women and 14% in men. The results imply that the concept of 'work stress' should be regarded in a wider context in order to understand gender related issues of exhaustion among vocationally active individuals.

Gender differences should be considered in vocational high schools so women and men can develop their potentials without being inhibited by gender bias. Gender mainstreaming in vocational high schools is a strategy to integrate gender differences at all stages in teaching-learning process for achieving gender equality and equity. This research evaluates the implementation of gender mainstreaming in vocational high schools consisting of seven key components of gender mainstreaming. Four vocational high schools in Sragen Regency Indonesia have been purposively selected. The data were obtained through in-depth interviews and documentation studies. The data were analyzed using Kabeer’s model of gender analysis. The findings show that not all key components of gender mainstreaming have been implemented in vocational high schools. Most vocational high schools have implemented three of seven key components of gender mainstreaming, namely political will and leadership, policy framework and gender statistics. Meanwhile four of seven key components of gender mainstreaming, namely structure and mechanism, resources, infra structures and civil society have not been well-implemented. In conclusion gender mainstreaming has not been implemented effectively in vocational high schools. Accordingly, the government’s education office should continue to encourage and publish guidelines on the implementation of gender-mainstreaming in vocational high schools.

Cai, T Tony; Zhang, Anru

2016-01-01

Motivated by differential co-expression analysis in genomics, we consider in this paper estimation and testing of high-dimensional differential correlation matrices. An adaptive thresholding procedure is introduced and theoretical guarantees are given. Minimax rate of convergence is established and the proposed estimator is shown to be adaptively rate-optimal over collections of paired correlation matrices with approximately sparse differences. Simulation results show that the procedure significantly outperforms two other natural methods that are based on separate estimation of the individual correlation matrices. The procedure is also illustrated through an analysis of a breast cancer dataset, which provides evidence at the gene co-expression level that several genes, of which a subset has been previously verified, are associated with the breast cancer. Hypothesis testing on the differential correlation matrices is also considered. A test, which is particularly well suited for testing against sparse alternatives, is introduced. In addition, other related problems, including estimation of a single sparse correlation matrix, estimation of the differential covariance matrices, and estimation of the differential cross-correlation matrices, are also discussed.

Vocational identity of deaf and hard of hearing adolescents

Directory of Open Access Journals (Sweden)

Šešum Mia

2016-01-01

Full Text Available Vocational identity development represents the key aspect of identity development and it is one of the most significant issues in the period of adolescence. The persons with strong vocational identity have clearer understanding of their own career goals and they are characterized by greater self-confidence and dedication to their career choices, which is the reason why they decide on their future profession more quickly and more easily than the persons whose vocational identity is weaker. The career development of deaf and hard of hearing adolescents takes place under conditions of auditory deprivation, which may have a negative effect on the stability of their vocational identity and thus on their choice of profession, employment and assimilation into the working environment. This study examines the connection between vocational identity of deaf and hard of hearing adolescents and the number of completed school years and age, as well as the effect of gender, the level of hearing impairment, primary mode of communication, and general performance at school at the end of a school term on vocational identity. The sample comprised 97 deaf and hard of hearing students attending seventh and eighth grades of primary school as well as all grades of secondary school, who are educated in segregating conditions in the territory of Serbia. 'My Vocational Situation' (MVS, Holland et al., 1980-a was used as the instrument. The results of the study, following the data analysis, point to the connection between vocational identity of deaf and hard of hearing adolescents and the number of school years completed and age, as well as the effect of gender on vocational identity, while the effect of the level of hearing impairment, primary mode of communication, and general performance at school on vocational identity of the examinees has not been confirmed. Comparing these results with the results of studies conducted on the population of typically developing

Wassermann, Anne Mai; Haebel, Peter; Weskamp, Nils; Bajorath, Jürgen

2012-07-23

We introduce the SAR matrix data structure that is designed to elucidate SAR patterns produced by groups of structurally related active compounds, which are extracted from large data sets. SAR matrices are systematically generated and sorted on the basis of SAR information content. Matrix generation is computationally efficient and enables processing of large compound sets. The matrix format is reminiscent of SAR tables, and SAR patterns revealed by different categories of matrices are easily interpretable. The structural organization underlying matrix formation is more flexible than standard R-group decomposition schemes. Hence, the resulting matrices capture SAR information in a comprehensive manner.

Full Text Available Since 2013, the university degree is free for everyone in Estonia. Vocational education has always been for free. University degrees have been valued as more academical, and vocational education because of the practical skills gained. There is a new trend in Estonia to enter into a vocational school after the university degree; and/or after one vocational education in to another vocational school. Study eagerness is always nice, but the question here is about the reason(s – is this kind of behaviour rather the sign of lifelong learning, or of wrong choices? In this question the research problem is included also – in case of wrong choices the waste of resources can be considered (from the point of view of society. In 2016, the National Audit Office of Estonia studied the progress of adults aged 25 and over, who had started acquiring vocational education (from 2010/2011 to 2014/2015 academic years before and during their studies, and in working life after the completion of their studies. The focus was on adults, because the decreasing number of young people in the state means that adults are and will remain an important target group for vocational education. The aim of this research is to analyze the background of the fact that many adults in Estonia with vocational education (36% or higher education (20% have started acquiring vocational education alongside adults without any professional education (44%. The subjects/respondents of this research were people who decided to influence the quality of their life through education. The object of the research were shcolars’ opinions about the type of education. In this research I focus on the opinion of students about university and/or vocational education. As an illustration, I discuss one case study of a highly educated person with two master degrees, who is going to start studying in a vocational school.

Krylov, Piotr

2017-01-01

This monograph is a comprehensive account of formal matrices, examining homological properties of modules over formal matrix rings and summarising the interplay between Morita contexts and K theory. While various special types of formal matrix rings have been studied for a long time from several points of view and appear in various textbooks, for instance to examine equivalences of module categories and to illustrate rings with one-sided non-symmetric properties, this particular class of rings has, so far, not been treated systematically. Exploring formal matrix rings of order 2 and introducing the notion of the determinant of a formal matrix over a commutative ring, this monograph further covers the Grothendieck and Whitehead groups of rings. Graduate students and researchers interested in ring theory, module theory and operator algebras will find this book particularly valuable. Containing numerous examples, Formal Matrices is a largely self-contained and accessible introduction to the topic, assuming a sol...

ESTIMATION OF FUNCTIONALS OF SPARSE COVARIANCE MATRICES.

Science.gov (United States)

Fan, Jianqing; Rigollet, Philippe; Wang, Weichen

High-dimensional statistical tests often ignore correlations to gain simplicity and stability leading to null distributions that depend on functionals of correlation matrices such as their Frobenius norm and other ℓ r norms. Motivated by the computation of critical values of such tests, we investigate the difficulty of estimation the functionals of sparse correlation matrices. Specifically, we show that simple plug-in procedures based on thresholded estimators of correlation matrices are sparsity-adaptive and minimax optimal over a large class of correlation matrices. Akin to previous results on functional estimation, the minimax rates exhibit an elbow phenomenon. Our results are further illustrated in simulated data as well as an empirical study of data arising in financial econometrics.

Discrete canonical transforms that are Hadamard matrices

International Nuclear Information System (INIS)

Healy, John J; Wolf, Kurt Bernardo

2011-01-01

The group Sp(2,R) of symplectic linear canonical transformations has an integral kernel which has quadratic and linear phases, and which is realized by the geometric paraxial optical model. The discrete counterpart of this model is a finite Hamiltonian system that acts on N-point signals through N x N matrices whose elements also have a constant absolute value, although they do not form a representation of that group. Those matrices that are also unitary are Hadamard matrices. We investigate the manifolds of these N x N matrices under the Sp(2,R) equivalence imposed by the model, and find them to be on two-sided cosets. By means of an algorithm we determine representatives that lead to collections of mutually unbiased bases.

The binary operation of usual addition is associative in all matrices over R. However, a binary operation of addition in matrices over Z/sub n/ of a nonassociative structures of AG-groupoids and AG-groups are defined and investigated here. It is shown that both these structures exist for every integer n >≥ 3. Various properties of these structures are explored like: (i) Every AG-groupoid of matrices over Z/sub n/ is transitively commutative AG-groupoid and is a cancellative AG-groupoid if n is prime. (ii) Every AG-groupoid of matrices over Z/sub n/ of Type-II is a T/sup 3/-AG-groupoid. (iii) An AG-groupoid of matrices over Z/sub n/ ; G /sub nAG/(t,u), is an AG-band, if t+u=1(mod n). (author)

Pathways to Work is a UK initiative aimed at supporting customers on incapacity benefits to return to work. This qualitative study complements previous evaluations of Pathways to Work by exploring customers' perceptions of the impact of the Condition Management Programme (CMP) offered to claimants with long-term health conditions. 39 customers took part in focus groups held at the seven sites where Pathways was originally piloted. The main focus of the discussions was on perceptions of the ways in which participation had impacted on health, well-being and return to work. The discussions were audio-recorded and fully transcribed for analysis using a text analysis framework to enable the development and refinement of categories and overarching patterns in the data. Perceived impacts on health and well-being included a more positive outlook, social contact, changed perceptions of conditions and improvements in health. Some customers also reported an increase in their vocational activity and others felt ready to embark on new activities. Factors associated with positive outcomes included the extent and quality of contact with CMP staff and practical advice about condition management. Factors impeding positive employment outcomes related mainly to obstacles to returning to work. The results indicated that CMP can assist customers to learn about and manage their health conditions and increase their vocational activity, and that CMP therefore provides a promising means of enabling people with long-term health conditions to regain a fulfilling, productive life.

2011-09-16

In this contribution, powdered activated carbons (ACs) from cork waste were supported for bar adsorptive micro-extraction (BAμE), as novel adsorbent phases for the analysis of polar compounds. By combining this approach with liquid desorption followed by high performance liquid chromatography with diode array detection (BAμE(AC)-LD/HPLC-DAD), good analytical performance was achieved using clofibric acid (CLOF) and ibuprofen (IBU) model compounds in environmental and biological matrices. Assays performed on 30 mL water samples spiked at the 25.0 μg L(-1) level yielded recoveries around 80% for CLOF and 95% for IBU, under optimized experimental conditions. The ACs textural and surface chemistry properties were correlated with the results obtained. The analytical performance showed good precision (0.9922) from 1.0 to 600.0 μg L(-1). By using the standard addition methodology, the application of the present approach to environmental water and urine matrices allowed remarkable performance at the trace level. The proposed methodology proved to be a viable alternative for acidic pharmaceuticals analysis, showing to be easy to implement, reliable, sensitive and requiring low sample volume to monitor these priority compounds in environmental and biological matrices.

2016-02-01

The Main purpose of vocational rehabilitation is occupational reintegration of clients into the job market who have lost their job or whose job is threatened because of a handicap or chronicl illness. With regard to existing evidence for the relevance of personality factors for work performance and job achievement, the present study investigated the influence of participants' personality factors on a successful reintegration after a retraining program in a vocational training center over 2 years. A central research objective was to identify prognostic personality factors for successful vocational integration. In this longitudinal study 15 vocational training centers participated at 3 time points of measurement (T1, T2 and T3). Data gathering was based on rehabilitants' self-reports (standardized questionnaires: SVF, BSW, SPR, CSES) about personality aspects. First data collection started at the beginning (T1) and a second survey was conducted at the end of the training 2 years later (T2). Based on the data at measurement points T1 and T2, 4 prognostic models were computed (binary logistic regression analysis) and evaluated, examining the differenzial influence of several scales and items on direct reintegration after completing the vocational retraining and reintegration status 6 months later (T3). As expected, different variables turned out to be relevant for occupational integration at the end of the training program and 6 months later. Correspondingly other variables appeared to be relevant for occupational reintegration at T1 and at T2. At the end of the vocational training program, approximately 24% of the participants had a job. With respect to direct reintegration, regression analysis revealed that vocational self-efficacy (R(2)=0,175) and self-evaluation were relevant (R(2)=0,383). Approximately 70% of the participants had gotten a job 6 months later. Several stress coping strategies (R(2)=0,170), estimation of the own reintegration prognosis and aspects

Synchronous correlation matrices and Connes’ embedding conjecture

Dykema, Kenneth J., E-mail: kdykema@math.tamu.edu [Department of Mathematics, Texas A& M University, College Station, Texas 77843-3368 (United States); Paulsen, Vern, E-mail: vern@math.uh.edu [Department of Mathematics, University of Houston, Houston, Texas 77204 (United States)

2016-01-15

In the work of Paulsen et al. [J. Funct. Anal. (in press); preprint arXiv:1407.6918], the concept of synchronous quantum correlation matrices was introduced and these were shown to correspond to traces on certain C*-algebras. In particular, synchronous correlation matrices arose in their study of various versions of quantum chromatic numbers of graphs and other quantum versions of graph theoretic parameters. In this paper, we develop these ideas further, focusing on the relations between synchronous correlation matrices and microstates. We prove that Connes’ embedding conjecture is equivalent to the equality of two families of synchronous quantum correlation matrices. We prove that if Connes’ embedding conjecture has a positive answer, then the tracial rank and projective rank are equal for every graph. We then apply these results to more general non-local games.

Krause, James S; Saunders, Lee L; Staten, David; Rohe, Daniel E

2011-04-01

To compare vocational interests as a function of sex and race among persons with recent spinal cord injury (SCI), because previous research used almost exclusively white men. Limited research from nearly 2 decades ago suggested SCI selectively occurs to men whose vocational interests are consistent with the Realistic theme of the Holland typology, indicative of a preference for activities and occupations requiring physical strength and dexterity. The Strong Interest Inventory (SII) was completed an average of 50 days after SCI onset. Data were collected at a specialty hospital and analyzed at a medical university. Adults with traumatic SCI (N=500) were assessed during inpatient rehabilitation. Not applicable. The SII, a 317-item measure of vocational interests. Although the findings for white men were consistent with elevation of the Realistic theme when compared with the reference group, the interests of women and black participants were substantially different. Women scored highest on Social, Enterprising, and Conventional themes compared with the reference group. Black participants reported significantly higher elevations than whites on 5 themes (all except Realistic), with elevations on the Social, Enterprising, and Conventional themes exceeding standardized norms. The Artistic and Investigative themes were least descriptive of the overall sample. Rehabilitation professionals should be aware of likely differences in patterns of vocational interests as a function of race and sex, and use vocational interests as a means of facilitating postinjury adaptation.

The Analysis on Emotional Education in Vocational School English Teaching

Institute of Scientific and Technical Information of China (English)

兰州职业技术学院 730070

2015-01-01

In the time of advancing quality education, emotion education has been paid more and more attention. English teaching is both language teaching progress and emotional communication progress. Therefore, emotional education is extremely important and indispensable in vocational school classroom teaching. However, the current application of vocational school emotional education in English classroom teaching is still relatively weak. Based on the theory of emotional education, this paper attempts to explore the methods and strategies of applying emotional education in vocational school English classroom teaching. It has important theoretical significance on promoting the comprehensive development of the vocational school students, improving English teaching effect, promoting the healthy and sustainable development of the vocational school education, and enriching and developing the emotional teaching psychology and cognitive psychology theory.

Chequered surfaces and complex matrices

International Nuclear Information System (INIS)

Morris, T.R.; Southampton Univ.

1991-01-01

We investigate a large-N matrix model involving general complex matrices. It can be reinterpreted as a model of two hermitian matrices with specific couplings, and as a model of positive definite hermitian matrices. Large-N perturbation theory generates dynamical triangulations in which the triangles can be chequered (i.e. coloured so that neighbours are opposite colours). On a sphere there is a simple relation between such triangulations and those generated by the single hermitian matrix model. For the torus (and a quartic potential) we solve the counting problem for the number of triangulations that cannot be quechered. The critical physics of chequered triangulations is the same as that of the hermitian matrix model. We show this explicitly by solving non-perturbatively pure two-dimensional ''chequered'' gravity. The interpretative framework given here applies to a number of other generalisations of the hermitian matrix model. (orig.)

Deveikis, A.; Kamuntavichius, G.

1996-01-01

A new method for calculation of shell model intrinsic density matrices, defined as two-particle density matrices integrated over the centre-of-mass position vector of two last particles and complemented with isospin variables, has been developed. The intrinsic density matrices obtained are completely antisymmetric, translation-invariant, and do not employ a group-theoretical classification of antisymmetric states. They are used for exact realistic density matrix expansion within the framework of the reduced Hamiltonian method. The procedures based on precise arithmetic for calculation of the intrinsic density matrices that involve no numerical diagonalization or orthogonalization have been developed and implemented in the computer code.

Does the public communication of science influence scientific vocation? Results of a national survey.

Science.gov (United States)

Stekolschik, Gabriel; Draghi, Cecilia; Adaszko, Dan; Gallardo, Susana

2010-09-01

The purpose of this work was to determine if public communication of science and technology (PCST) has any influence on people's decision to become dedicated to scientific research. For this reason, a national survey involving 852 researchers from all disciplines was conducted in Argentina. The results showed that the factors affecting scientific vocation are many, and that, regardless of differences in gender, age or discipline, the greatest influence on the decision to go into scientific research is exerted by teachers. The analysis also demonstrated that different manifestations of PCST (science books, press articles, audiovisual material, and activities such as visits to science museums) play a significant role in awakening the vocation for science. From these results it may be stated that PCST--in addition to its function of informing and forming citizens--exerts a significant influence in fostering scientific vocation.

2014-10-01

The consumption of polyphenols in green tea has been associated with beneficial health effects. Although polyphenols are unstable in the intestinal environment, they may be protected by interactions with dairy proteins during digestion. The objectives of this study were to evaluate the effect of a green tea extract on the digestibility of different dairy matrices and to monitor the antioxidant activity of these matrices with or without the green tea extract during digestion in a simulated gastrointestinal environment. Milk, yogurt and cheese with similar fat-to-protein ratios were subjected to simulated digestion. Matrix degradation, protein and fat hydrolysis, polyphenol concentration and radical scavenging activity were analyzed during gastric and intestinal digestion phases. Cheese was the matrix most resistant to protein and fat digestion. The addition of the green tea extract significantly decreased proteolysis in the gastric phase but had no effect in the intestinal phase. The kinetics of fatty acid release was reduced by the presence of the green tea extract. Transition from the gastric phase to the intestinal phase induced a 50% decrease in the antioxidant activity of the control (tea extract dispersed in water) due to the degradation of polyphenols. The presence of dairy matrices significantly improved polyphenol stability in the intestinal phase and increased the antioxidant activity by 29% (cheese) to 42% (milk) compared to the control. These results suggest that simultaneous consumption of green tea and dairy products helps to maintain the integrity and antioxidant activity of polyphenols during digestion.

The replacement of diseased tissues with biological substitutes with suitable biomechanical properties is one of the most important goal in tissue engineering. Collagen represents a satisfactory choice for scaffolds. Unfortunately, the lack of elasticity represents a restriction to a wide use of collagen for several applications. In this work, we studied the effect of human elastin-like polypeptide (HELP) as hybrid collagen-elastin matrices. In particular, we studied the biomechanical properties of collagen/HELP scaffolds considering several components involved in ECM remodeling (elastin, collagen, fibrillin, lectin-like receptor, metalloproteinases) and cell phenotype (myogenin, myosin heavy chain) with particular awareness for vascular tissue engineering applications. Elastin and collagen content resulted upregulated in collagen-HELP matrices, even showing an improved structural remodeling through the involvement of proteins to a ECM remodeling activity. Moreover, the hybrid matrices enhanced the contractile activity of C2C12 cells concurring to improve the mechanical properties of the scaffold. Finally, small-angle X-ray scattering analyses were performed to enable a very detailed analysis of the matrices at the nanoscale, comparing the scaffolds with native blood vessels. In conclusion, our work shows the use of recombinant HELP, as a very promising complement able to significantly improve the biomechanical properties of three-dimensional collagen matrices in terms of tensile stress and elastic modulus. © 2014 Wiley Periodicals, Inc.

Random matrices and random difference equations

International Nuclear Information System (INIS)

Uppuluri, V.R.R.

1975-01-01

Mathematical models leading to products of random matrices and random difference equations are discussed. A one-compartment model with random behavior is introduced, and it is shown how the average concentration in the discrete time model converges to the exponential function. This is of relevance to understanding how radioactivity gets trapped in bone structure in blood--bone systems. The ideas are then generalized to two-compartment models and mammillary systems, where products of random matrices appear in a natural way. The appearance of products of random matrices in applications in demography and control theory is considered. Then random sequences motivated from the following problems are studied: constant pulsing and random decay models, random pulsing and constant decay models, and random pulsing and random decay models

Quantum Entanglement and Reduced Density Matrices

Science.gov (United States)

Purwanto, Agus; Sukamto, Heru; Yuwana, Lila

2018-05-01

We investigate entanglement and separability criteria of multipartite (n-partite) state by examining ranks of its reduced density matrices. Firstly, we construct the general formula to determine the criterion. A rank of origin density matrix always equals one, meanwhile ranks of reduced matrices have various ranks. Next, separability and entanglement criterion of multipartite is determined by calculating ranks of reduced density matrices. In this article we diversify multipartite state criteria into completely entangled state, completely separable state, and compound state, i.e. sub-entangled state and sub-entangledseparable state. Furthermore, we also shorten the calculation proposed by the previous research to determine separability of multipartite state and expand the methods to be able to differ multipartite state based on criteria above.

This needs to be addressed by LPTK as producer vocational teacher candidate, so that future graduates are able to fulfill the mandate of the curriculum. Curriculum vocational teacher candidates who applied seems also still focused on providing hard skills competencies, so that graduates do not have adequate soft skills competence. On the other hand in the world of work has been going on trend shift in terms of hard skills to soft skills.Research and development is designed to go through stages and multiyear to produce soft skills development strategy for prospective teachers of vocational school.

Malware analysis using visualized image matrices.

Science.gov (United States)

Han, KyoungSoo; Kang, BooJoong; Im, Eul Gyu

2014-01-01

This paper proposes a novel malware visual analysis method that contains not only a visualization method to convert binary files into images, but also a similarity calculation method between these images. The proposed method generates RGB-colored pixels on image matrices using the opcode sequences extracted from malware samples and calculates the similarities for the image matrices. Particularly, our proposed methods are available for packed malware samples by applying them to the execution traces extracted through dynamic analysis. When the images are generated, we can reduce the overheads by extracting the opcode sequences only from the blocks that include the instructions related to staple behaviors such as functions and application programming interface (API) calls. In addition, we propose a technique that generates a representative image for each malware family in order to reduce the number of comparisons for the classification of unknown samples and the colored pixel information in the image matrices is used to calculate the similarities between the images. Our experimental results show that the image matrices of malware can effectively be used to classify malware families both statically and dynamically with accuracy of 0.9896 and 0.9732, respectively.

The production and evaluation of cornstarch/cellulose acetate/silver sulfadiazine extrudate matrices are reported herein. The matrices were melt extruded under nine different conditions, altering the temperature and the screw speed values. The surface morphology of the matrices was examined by scanning electron microscopy. The micrographs revealed the presence of non-melted silver sulfadiazine microparticles in the matrices extruded at lower temperature and screw speed values. The thermal properties were evaluated and the results for both the biopolymer and the drug indicated no thermal degradation during the melt extrusion process. The differential scanning analysis of the extrudate matrices showed a shift to lower temperatures for the silver sulfadiazine melting point compared with the non-extruded drug. The starch/cellulose acetate matrices containing silver sulfadiazine demonstrated significant inhibition of the growth of Pseudomonas aeruginosa and Staphylococcus aureus. In vivo inflammatory response tests showed that the extrudate matrices, with or without silver sulfadiazine, did not trigger chronic inflammatory processes. - Highlights: • Melt extruded bio-based matrices containing silver sulfadiazine was produced. • The silver sulfadiazine is stable during melt-extrusion. • The extrudate matrices shown bacterial growth inhibition. • The matrices obtained have potential to development wound healing membranes.

Polynomial sequences generated by infinite Hessenberg matrices

Verde-Star Luis

2017-01-01

Full Text Available We show that an infinite lower Hessenberg matrix generates polynomial sequences that correspond to the rows of infinite lower triangular invertible matrices. Orthogonal polynomial sequences are obtained when the Hessenberg matrix is tridiagonal. We study properties of the polynomial sequences and their corresponding matrices which are related to recurrence relations, companion matrices, matrix similarity, construction algorithms, and generating functions. When the Hessenberg matrix is also Toeplitz the polynomial sequences turn out to be of interpolatory type and we obtain additional results. For example, we show that every nonderogative finite square matrix is similar to a unique Toeplitz-Hessenberg matrix.

Vocational education is positioned within the framework of Vocational Education for All. Therefore, the alignment between the world of education and the world of work is an issue that is always actual within the framework of vocational education, including being an actual issue for people with disabilities. This article aims to map how the state frames disability and vocational education issues within the framework of public policy. The research was conducted using qualitative research method in which the data obtained from the study of documentation. Analysis of the data using content analysis. The results of the study show that the State Policy has not fully framed the issue of vocational education for the disabled into special policies. The vocational education policy for the disabled is still integrated in the major policies in certain institutions. No policy innovations have yet significantly provided a special place for the disabled.

S-matrices and integrability

International Nuclear Information System (INIS)

2016-01-01

In these notes we review the S-matrix theory in (1+1)-dimensional integrable models, focusing mainly on the relativistic case. Once the main definitions and physical properties are introduced, we discuss the factorization of scattering processes due to integrability. We then focus on the analytic properties of the two-particle scattering amplitude and illustrate the derivation of the S-matrices for all the possible bound states using the so-called bootstrap principle. General algebraic structures underlying the S-matrix theory and its relation with the form factors axioms are briefly mentioned. Finally, we discuss the S-matrices of sine-Gordon and SU (2), SU (3) chiral Gross–Neveu models. (topical review)

Abstract of interjection and vocative position in Persian grammar and semantics

2014-12-01

Full Text Available Abstract Vocative is a role that noun accepts it and usually used in Persian language with interjection letters i.e. "Ey", "Ya" and "Alef" that is attached to the end of the noun. By combining the definitions that have been mentioned for vocative in grammar books, it can be concluded that vocative is a noun that is addressed whether it is a real address or figurative. The verbal symbol of vocative is "Ey" and its synonyms in sentence that sometimes these symbols are deleted from sentence and the change of word's song is replaced it. Vocative and more precisely the core of vocative may be deleted from the sentence. Vocative deletion in sentence is among problems that grammarians have paid less attention to it in vocative subject. In a general overview, vocative can be divided into two mentioned and deleted sectors.When vocative is mentioned in sentence it can be explicit or ironic name but deleted vocative includes following types: 1. Some cases that participle or interpretable phrase to participle is used after the interjection letter (Ey that sometimes in this case the conjunction letter "Ke" is used after the interjection letter, for example: Ey ke dar koshtan-e ma hich modara nakoni Soud-o sarmaye besouzi-o mohaba nakoni(Hafez, 1990: 340 And sometimes it has been used without "Ke", for example:                           Ey az banafshe sakhte bar gol mesalha Dar aftab karde ze anbar kolalha (Sanaei, 2001: 801 2. Some cases that speaker pronouns of "I" and "We" are used after the interjection letter "Ey" and the phrase after the letter "Ey" can be totally considered as an adjective for the deleted core of vocative, for example:     Narges kereshme mibarad az had boroun khoram Ey man faday-e shive-ye chashme siyah-e to (Hafez, 1990: 284 In Persian texts, some evidences are also found that the letter "Ey" is not used for addressing in them.In the structure of these types, no vocative has been mentioned in the sentence

Hierarchical quark mass matrices

International Nuclear Information System (INIS)

Rasin, A.

1998-02-01

I define a set of conditions that the most general hierarchical Yukawa mass matrices have to satisfy so that the leading rotations in the diagonalization matrix are a pair of (2,3) and (1,2) rotations. In addition to Fritzsch structures, examples of such hierarchical structures include also matrices with (1,3) elements of the same order or even much larger than the (1,2) elements. Such matrices can be obtained in the framework of a flavor theory. To leading order, the values of the angle in the (2,3) plane (s 23 ) and the angle in the (1,2) plane (s 12 ) do not depend on the order in which they are taken when diagonalizing. We find that any of the Cabbibo-Kobayashi-Maskawa matrix parametrizations that consist of at least one (1,2) and one (2,3) rotation may be suitable. In the particular case when the s 13 diagonalization angles are sufficiently small compared to the product s 12 s 23 , two special CKM parametrizations emerge: the R 12 R 23 R 12 parametrization follows with s 23 taken before the s 12 rotation, and vice versa for the R 23 R 12 R 23 parametrization.

Elliot, Catherine; Lang, Christin; Brand, Serge; Holsboer-Trachsler, Edith; Pühse, Uwe; Gerber, Markus

2015-04-01

This study examines how students who met the current recommendations for vigorous physical activity (VPA) of the American College of Sports Medicine (ACSM) and the Centers of Disease Control and Prevention (CDC) differ from peers who did not reach these standards with regard to self-reported burnout, before and after controlling for light physical activity and moderate physical activity. A sample of 144 vocational students (Mage =16.2 years, SD = 1.13, 98 males) completed the International Physical Activity Questionnaire, the Shirom-Melamed Burnout Measure, and the School Burnout Inventory. Bivariate correlations revealed that only VPA was associated with reduced burnout. Both the ACSM and CDC guidelines were useful to identify significant differences in burnout symptoms between students who met versus did not meet the standards. Health policy makers should develop strategies to integrate more VPA into the lives of adolescent students so as to reach a minimum of 60 min per week.

METHODOLOGICAL GUIDELINES FOR THE TRANSPROFESSIONALISM DEVELOPMENT AMONG VOCATIONAL EDUCATORS

Directory of Open Access Journals (Sweden)

E. F. Zeer

2017-01-01

Full Text Available Introduction. Nowadays, regarding the 6thwave of technological innovations and emergence of a phenomenon «transfession», there is a need for modernization of the vocational staff training in our country. Transfession is a type of the labour activity realized on the basis of synthesis and convergence of the professional competences that involve different specialized areas. Thus, the authors of the present article propose to use the professional and educational platform, developed by them, taking into account a specialists’ training specialty. The aims of the article are the following: to describe the phenomenon «transprofessionalism», to determine the initial attitudes towards its understanding; to present the block-modular model of the platform for the formation of the transprofessionalism of the teachers of the vocational school. Methodology and research methods. The research is based on the following theoretical and scientific methods: analysis, synthesis, concretization, generalization; hypothetical-deductive method; project-based method. The projecting of the transprofessionalism platform model was constructed on the basis of multidimensional, transdisciplinary, network and project approaches. Results and scientific novelty. The relevance of the discussed phenomenon in the productive-economic sphere is proved. The transprofessionalism requires a brand new content-informative and technological training of specialists. In particular, the concept «profession» has lost its original meaning as an area of the social division of labour during socio-technological development of the Russian economy. Therefore, transprofessionals are becoming more competitive and demanded in the employment market, being capable to perform a wide range of specialized types of professional activities. The structure, principles and mechanisms of the professional-educational platform functioning for transprofessionalism formation among the members of professional

Accelerating Matrix-Vector Multiplication on Hierarchical Matrices Using Graphical Processing Units

KAUST Repository

Boukaram, W.

2015-03-25

Large dense matrices arise from the discretization of many physical phenomena in computational sciences. In statistics very large dense covariance matrices are used for describing random fields and processes. One can, for instance, describe distribution of dust particles in the atmosphere, concentration of mineral resources in the earth\\'s crust or uncertain permeability coefficient in reservoir modeling. When the problem size grows, storing and computing with the full dense matrix becomes prohibitively expensive both in terms of computational complexity and physical memory requirements. Fortunately, these matrices can often be approximated by a class of data sparse matrices called hierarchical matrices (H-matrices) where various sub-blocks of the matrix are approximated by low rank matrices. These matrices can be stored in memory that grows linearly with the problem size. In addition, arithmetic operations on these H-matrices, such as matrix-vector multiplication, can be completed in almost linear time. Originally the H-matrix technique was developed for the approximation of stiffness matrices coming from partial differential and integral equations. Parallelizing these arithmetic operations on the GPU has been the focus of this work and we will present work done on the matrix vector operation on the GPU using the KSPARSE library.

Mastronardi and Van Dooren [SIAM J. Matrix Anal. Appl., 34 (2013), pp. 173-196] recently introduced the block antitriangular ("Batman") decomposition for symmetric indefinite matrices. Here we show the simplification of this factorization for saddle point matrices and demonstrate how it represents the common nullspace method. We show that rank-1 updates to the saddle point matrix can be easily incorporated into the factorization and give bounds on the eigenvalues of matrices important in saddle point theory. We show the relation of this factorization to constraint preconditioning and how it transforms but preserves the structure of block diagonal and block triangular preconditioners. © 2014 Society for Industrial and Applied Mathematics.

Vocation in theology-based nursing theories.

Science.gov (United States)

Lundmark, Mikael

2007-11-01

By using the concepts of intrinsicality/extrinsicality as analytic tools, the theology-based nursing theories of Ann Bradshaw and Katie Eriksson are analyzed regarding their explicit and/or implicit understanding of vocation as a motivational factor for nursing. The results show that both theories view intrinsic values as guarantees against reducing nursing practice to mechanistic applications of techniques and as being a way of reinforcing a high ethical standard. The theories explicitly (Bradshaw) or implicitly (Eriksson) advocate a vocational understanding of nursing as being essential for nursing theories. Eriksson's theory has a potential for conceptualizing an understanding of extrinsic and intrinsic motivational factors for nursing but one weakness in the theory could be the risk of slipping over to moral judgments where intrinsic factors are valued as being superior to extrinsic. Bradshaw's theory is more complex and explicit in understanding the concept of vocation and is theologically more plausible, although also more confessional.

2014-01-01

This new edition illustrates the power of linear algebra in the study of graphs. The emphasis on matrix techniques is greater than in other texts on algebraic graph theory. Important matrices associated with graphs (for example, incidence, adjacency and Laplacian matrices) are treated in detail. Presenting a useful overview of selected topics in algebraic graph theory, early chapters of the text focus on regular graphs, algebraic connectivity, the distance matrix of a tree, and its generalized version for arbitrary graphs, known as the resistance matrix. Coverage of later topics include Laplacian eigenvalues of threshold graphs, the positive definite completion problem and matrix games based on a graph. Such an extensive coverage of the subject area provides a welcome prompt for further exploration. The inclusion of exercises enables practical learning throughout the book. In the new edition, a new chapter is added on the line graph of a tree, while some results in Chapter 6 on Perron-Frobenius theory are reo...

Symmetric Positive Definite (SPD) matrices emerge as data descriptors in several applications of computer vision such as object tracking, texture recognition, and diffusion tensor imaging. Clustering these data matrices forms an integral part of these applications, for which soft-clustering algorithms (K-Means, expectation maximization, etc.) are generally used. As is well-known, these algorithms need the number of clusters to be specified, which is difficult when the dataset scales. To address this issue, we resort to the classical nonparametric Bayesian framework by modeling the data as a mixture model using the Dirichlet process (DP) prior. Since these matrices do not conform to the Euclidean geometry, rather belongs to a curved Riemannian manifold,existing DP models cannot be directly applied. Thus, in this paper, we propose a novel DP mixture model framework for SPD matrices. Using the log-determinant divergence as the underlying dissimilarity measure to compare these matrices, and further using the connection between this measure and the Wishart distribution, we derive a novel DPM model based on the Wishart-Inverse-Wishart conjugate pair. We apply this model to several applications in computer vision. Our experiments demonstrate that our model is scalable to the dataset size and at the same time achieves superior accuracy compared to several state-of-the-art parametric and nonparametric clustering algorithms.

Poreh, A M; Schullen, C

1998-10-01

This study investigated the relationship between scores on scales that purport to measure psychosis-proneness and scores on vocational interests, identity, and differentiation scales in a sample of 233 college students who completed the Perceptual Aberration and Magical Ideation scales, the Strong Campbell Interest Inventory, and the Career Decision Scale. The present findings are consistent with prior work indicating a sex-related association of scores on measures of psychosis-proneness and vocational interests. A positive correlation between scores on vocational indecision and measures of psychosis-proneness was also found, suggesting that both men and women who score high on psychosis-proneness find it difficult to formulate long-term career goals. Finally, there was no significant correlation between scores on measures of psychosis-proneness and Holland's Vocational Differentiation Index. Present results are discussed in light of previously reported sex differences among psychosis-prone adults and diagnosed schizophrenics. The implications of the findings for vocational counselors are also addressed.

Dropout in vocational education

DEFF Research Database (Denmark)

Jørgensen, Christian Helms

For the last ten years drop out of vocational education has increased strongly in Denmark. Only half of the students, who take up a vocational programme on upper secondary level, complete it. Like in other European countries the low completion rates has caused considerable alarm on the political...... level (Lamb and Markussen 2011). Continuing high dropout rates will make it very hard for the government to reach its target for educational completion, and the government has launched a series of measures to increase retention including the obligation for all colleges to make plans for retention...... and monitor the progress in achieving the goals. The questions addressed in this paper are why and how dropout in VET takes place. The objective is to provide more detailed and qualified knowledge of the complex processes of dropping out....

Shimo, M.; Seki, K.; Kikuchi, I.

1992-01-01

The tidal volume was estimated for evaluating the effective dose due to radon concentration in the atmosphere. In this study regional population was separated to vocation and non-vocation. The occupancy time and the breathing rate for both vocation and non-vocation groups were estimated, and the annual tidal volume for both groups were calculated. Human actions were separated to 18 activities in the process for estimating the breathing rate. It was clear that the breathing rate depended on human activity and that the human activity changed with its age, so the breathing rate varied with age. Finally the effective doses due to radon and radon progeny indoors and outdoors were evaluated. The maximum annual effective dose was estimated to be 1.2 mSv, minimum 0.2 mSv, and mean 0.51 mSv for vocation. For non-vocation, the male maximum value 0.43 mSv was obtained at the 16 age and the minimum 0.12 mSv at the 70 age, whereas female maximum 0.26 mSv was obtained at the 12 age and the minimum 0.11 mSv at the 70 age. In addition in this study objective areas are Aichi, Gifu, and Mie prefectures for vocation and only Aichi prefecture for non-vocation. (author)

The modern numerical methods for solving the linear algebraic systems Au = f with high order sparse matrices A, which arise in grid approximations of multidimensional boundary value problems, are based mainly on accelerated iterative processes with easily invertible preconditioning matrices presented in the form of approximate (incomplete) factorization of the original matrix A. We consider some recent algorithmic approaches, theoretical foundations, experimental data and open questions for incomplete factorization of Stiltijes matrices which are {open_quotes}the best{close_quotes} ones in the sense that they have the most advanced results. Special attention is given to solving the elliptic differential equations with strongly variable coefficients, singular perturbated diffusion-convection and parabolic equations.

Interactions between Food Additive Silica Nanoparticles and Food Matrices

Directory of Open Access Journals (Sweden)

Mi-Ran Go

2017-06-01

Full Text Available Nanoparticles (NPs have been widely utilized in the food industry as additives with their beneficial characteristics, such as improving sensory property and processing suitability, enhancing functional and nutritional values, and extending shelf-life of foods. Silica is used as an anti-caking agent to improve flow property of powered ingredients and as a carrier for flavors or active compounds in food. Along with the rapid development of nanotechnology, the sizes of silica fall into nanoscale, thereby raising concerns about the potential toxicity of nano-sized silica materials. There have been a number of studies carried out to investigate possible adverse effects of NPs on the gastrointestinal tract. The interactions between NPs and surrounding food matrices should be also taken into account since the interactions can affect their bioavailability, efficacy, and toxicity. In the present study, we investigated the interactions between food additive silica NPs and food matrices, such as saccharides, proteins, lipids, and minerals. Quantitative analysis was performed to determine food component-NP corona using HPLC, fluorescence quenching, GC-MS, and ICP-AES. The results demonstrate that zeta potential and hydrodynamic radius of silica NPs changed in the presence of all food matrices, but their solubility was not affected. However, quantitative analysis on the interactions revealed that a small portion of food matrices interacted with silica NPs and the interactions were highly dependent on the type of food component. Moreover, minor nutrients could also affect the interactions, as evidenced by higher NP interaction with honey rather than with a simple sugar mixture containing an equivalent amount of fructose, glucose, sucrose, and maltose. These findings provide fundamental information to extend our understanding about the interactions between silica NPs and food components and to predict the interaction effect on the safety aspects of food

2014-01-01

Due to the high toxicity of endocrine disruptors (EDs), studies are being undertaken to design effective techniques for separation and detection of EDs in various matrices. Recently, research activities in this area have shown that a diverse range of chromatographic techniques are available for the quantification and analysis of EDs. Therefore, on the basis of significant, recent original publications, we aimed at providing an overview of different separation and detection methods for the determination of trace-level concentrations of selected EDs. The biological effects of EDs and current pretreatment techniques applied to EDs are also discussed. Various types of chromatographic techniques are presented for quantification, highlighting time- and cost-effective techniques that separate and quantify trace levels of multiple EDs from various environmental matrices. Reports related to methods for the quantification of EDs from various matrices primarily published since 2008 have been cited.

Effects of Welfare Reform on Vocational Education and Training

Dave, Dhaval M.; Reichman, Nancy E.; Corman, Hope; Das, Dhiman

2011-01-01

Exploiting variation in welfare reform across states and over time and using relevant comparison groups, this study estimates the effects of welfare reform on an important source of human capital acquisition among women at risk for relying on welfare: vocational education and training. The results suggest that welfare reform reduced enrollment in full-time vocational education and had no significant effects on part-time vocational education or participation in other types of work-related courses, though there appears to be considerable heterogeneity across states with respect to the strictness of educational policy and the strength of work incentives under welfare reform. In addition, we find evidence of heterogeneous effects by prior educational attainment. We find no evidence that the previously-observed negative effects of welfare reform on formal education (including college enrollment), which we replicated in this study, have been offset by increases in vocational education and training.

Hook, Misty K; Bowman, Sharon

2008-01-01

While lesbians are similar to other women in that they face discrimination in the workplace based on gender, ethnicity and class, they also have unique needs and confront bias because of their sexual orientation. Thus, choosing an occupation is an extremely important task for many lesbians. In order to adequately serve a lesbian population, vocational counselors need to be aware of how lesbians choose occupations. Astin's (1985) and Gottfredson's (1981) theories of career development can be adapted to help explain the vocational needs of lesbians. This article will review the major findings within the field, discuss how the two theories relate to the vocational decision-making process of lesbian women and make suggestions for how to do vocational counseling with lesbians.

2017-01-01

With the development of economy, the importance of accounting is becoming more and more prominent, and the requirements of relevant industries for accountting have been gradually raised. so more and more people learn accounting, but the the effect of practical teaching in college is not ideal. Taking secondary vocational school as an example, although the accounting is one of the major with long history since secondary vocational colleges started to run, but due to various factors, accounting teaching in secondary vocational colleges is not up to the requirement of the society. Moreover, the teaching quality and teaching efficiency are relatively low, so the status of secondary vocational school is also low in the whole education circle. In order to improve the quality of cultivating professional skills for accounting in secondary vocational schools, and promote the development of accounting teaching in secondary vocational schools, this paper analyzes the current professional skills training for accounting in secondary vocational colleges.

Wihlman, Ulla; Lundborg, Cecilia Stålsby; Holmström, Inger; Axelsson, Runo

2011-01-01

This study describes and analysis five years of experiences from organising an interorganisational project on vocational rehabilitation. A qualitative case study approach was used based on interviews, focus group discussions and documents. The aim was to analyse how and why the project was organised in the way it was in relation to theories of integration, organisational change and learning. The results show that the vocational rehabilitation project was initiated mainly for financial reasons. It was organised as a mechanistic system with the aim of producing different activities, where financial control and support from all the levels of the organisations involved was important. A new bureaucracy between the different authorities involved was built up, where the vertical (top-down) integration was more important than the horizontal. The result was scattered islands of interprofessional work in different teams, but without contacts between them. The project did not influence the processes or workflows of the organisations involved in the project, which would be important from a service-user perspective. It may therefore be questionnable to organise the development of interorganisational integration for vocational rehabilitation in a separate project organisation. Instead, interorganisational networks with focus on interconnections of processes and workflows may be more flexible and adaptable. Copyright © 2010 John Wiley & Sons, Ltd.

Returning to work after spinal cord injury (SCI) is a complex process due to the nature of injury and its devastating effect on all aspects of patients. This case study report is based on a spinal cord injury centre of Bangladesh. The evaluation examined vocational assessment process and vocational interest of persons with SCI undergoing rehabilitation program in the center. Occupational Therapists were interviewed to understand the existing vocational assessment services. This study also used data from 183 vocational assessment forms to find out the association of vocational interests and other demographic factors. The vocational assessment conducted to gathered information on the physical capacity of the patient and physical environment of patients living area only. The most preferred vocational interest was shop management 39%, and returning to previous job 38%. Vocational trades with the lowest level of interest were computer (2%) and electronics (3%), and 10% of patients at the time of assessment were undecided. A statistically significant association between interest to return to previous job and gender, age, occupation before injury and living area were found. Patients go through a complex process to adapt to a new life after experiencing SCI which is significantly influenced by the rehabilitation professionals around him/her. A comprehensive assessment including psychosocial information and therapist's expertise on facilitations making vocational decision based on the variables can optimize the rehabilitation outcome.

Critics of vocational education do not recognize its potential to develop outcomes similar to general education. Vocational curriculum should be based on a holistic integrated model of competence, stressing problem solving and workplace learning, that might serve as the model for general curriculum. (SK)

Loop diagrams without γ matrices

McKeon, D.G.C.; Rebhan, A.

1993-01-01

By using a quantum-mechanical path integral to compute matrix elements of the form left-angle x|exp(-iHt)|y right-angle, radiative corrections in quantum-field theory can be evaluated without encountering loop-momentum integrals. In this paper we demonstrate how Dirac γ matrices that occur in the proper-time ''Hamiltonian'' H lead to the introduction of a quantum-mechanical path integral corresponding to a superparticle analogous to one proposed recently by Fradkin and Gitman. Direct evaluation of this path integral circumvents many of the usual algebraic manipulations of γ matrices in the computation of quantum-field-theoretical Green's functions involving fermions

The use of equilibrium-based and mass transfer-based leaching tests has been proposed to provide an integrated assessment of leaching processes from solid wastes. The objectives of the research presented here are to (i) validate this assessment approach for contaminated soils and cement-based matrices, (ii) evaluate the use of diffusion and coupled dissolution-diffusion models for estimating constituent release, and (iii) evaluate model parameterization using results from batch equilibrium leaching tests and physical characterization. The test matrices consisted of (i) a soil contaminated with arsenic from a pesticide production facility, (ii) the same soil subsequently treated by a Portland cement stabilization/solidification (S/S) process, and (iii) a synthetic cement-based matrix spiked with arsenic(III) oxide. Results indicated that a good assessment of contaminant release from contaminated soils and cement-based S/S treated wastes can be obtained by the integrated use of equilibrium-based and mass transfer-based leaching tests in conjunction with the appropriate release model. During the time scale of laboratory testing, the release of arsenic from the contaminated soil matrix was governed by diffusion and the solubility of arsenic in the pore solution while the release of arsenic from the cement-based matrices was mainly controlled by solubilization at the interface between the matrix and the bulk leaching solution. In addition, results indicated that (i) estimation of the activity coefficient within the matrix pore water is necessary for accurate prediction of constituent release rates and (ii) inaccurate representation of the factors controlling release during laboratory testing can result in significant errors in release estimates.

2018-01-01

Gene-activated matrix (GAM)-based therapeutics for tissue regeneration are limited by efficacy, the lack of spatiotemporal control and availability of target cells, all of which impact negatively on their translation to the clinic. Here, an advanced ultrasound-responsive GAM is described containing target cells that facilitates matrix-assisted sonoporation (MAS) to induce osteogenic differentiation. Ultrasound-responsive GAMs consisting of fibrin/collagen hybrid-matrices containing microbubbles, bone morphogenetic protein BMP2/7 coexpression plasmids together with C2C12 cells were treated with ultrasound either in vitro or following parenteral intramuscular implantation in vivo. Using direct measurement for alkaline phosphatase activity, von Kossa staining and immunohistochemical analysis for osteocalcin expression, MAS-stimulated osteogenic differentiation was confirmed in the GAMs in vitro 7 days after treatment with ultrasound. At day 30 post-treatment with ultrasound, ectopic osteogenic differentiation was confirmed in vivo using X-ray microcomputed tomography and histological analysis. Osteogenic differentiation was indicated by the presence of ectopic bone structures in all animals treated with MAS. In addition, bone volumes in this group were statistically greater than those in the control groups. This novel approach of incorporating a MAS capability into GAMs could be exploited to facilitate ex vivo gene transfer with subsequent surgical implantation or alternatively provide a minimally invasive means of stimulating in situ transgene delivery for osteoinductive gene-based therapies.

Chain of matrices, loop equations and topological recursion

CERN Document Server

Orantin, Nicolas

2009-01-01

Random matrices are used in fields as different as the study of multi-orthogonal polynomials or the enumeration of discrete surfaces. Both of them are based on the study of a matrix integral. However, this term can be confusing since the definition of a matrix integral in these two applications is not the same. These two definitions, perturbative and non-perturbative, are discussed in this chapter as well as their relation. The so-called loop equations satisfied by integrals over random matrices coupled in chain is discussed as well as their recursive solution in the perturbative case when the matrices are Hermitean.

Recently low displacement rank (LDR) matrices, or so-called structured matrices, have been proposed to compress large-scale neural networks. Empirical results have shown that neural networks with weight matrices of LDR matrices, referred as LDR neural networks, can achieve significant reduction in space and computational complexity while retaining high accuracy. We formally study LDR matrices in deep learning. First, we prove the universal approximation property of LDR neural networks with a ...

Barriers to participation in vocational orientation programmes among prisoners

Directory of Open Access Journals (Sweden)

Dorien Brosens

2015-11-01

Full Text Available This study investigates the barriers to prisoners’ participation in vocational education, as well as the predictors of different types of barriers. Survey data derived from a project in a remand prison in Belgium (N=468 provided the empirical evidence for the analyses. The results indicate that facing situational and informational barriers are most common. Based on the different kinds of barriers, various types of non-participants can be distinguished and multinomial logistic regression analyses are conducted to identify in what way participants of vocational education differ from various types of non-participants. For instance, prisoners with a poor understanding of the Dutch language and those who never/rarely receive visitors participate less in vocational education as they are more likely to be confronted with informational barriers. We conclude this article by discussing paths for future research and implications for policy and practice to anticipate the barriers for those who want to participate in vocational education.

Data depth and rank-based tests for covariance and spectral density matrices

KAUST Repository

Chau, Joris

2017-06-26

In multivariate time series analysis, objects of primary interest to study cross-dependences in the time series are the autocovariance or spectral density matrices. Non-degenerate covariance and spectral density matrices are necessarily Hermitian and positive definite, and our primary goal is to develop new methods to analyze samples of such matrices. The main contribution of this paper is the generalization of the concept of statistical data depth for collections of covariance or spectral density matrices by exploiting the geometric properties of the space of Hermitian positive definite matrices as a Riemannian manifold. This allows one to naturally characterize most central or outlying matrices, but also provides a practical framework for rank-based hypothesis testing in the context of samples of covariance or spectral density matrices. First, the desired properties of a data depth function acting on the space of Hermitian positive definite matrices are presented. Second, we propose two computationally efficient pointwise and integrated data depth functions that satisfy each of these requirements. Several applications of the developed methodology are illustrated by the analysis of collections of spectral matrices in multivariate brain signal time series datasets.

Almost commuting self-adjoint matrices: The real and self-dual cases

Science.gov (United States)

Loring, Terry A.; Sørensen, Adam P. W.

2016-08-01

We show that a pair of almost commuting self-adjoint, symmetric matrices is close to a pair of commuting self-adjoint, symmetric matrices (in a uniform way). Moreover, we prove that the same holds with self-dual in place of symmetric and also for paths of self-adjoint matrices. Since a symmetric, self-adjoint matrix is real, we get a real version of Huaxin Lin’s famous theorem on almost commuting matrices. Similarly, the self-dual case gives a version for matrices over the quaternions. To prove these results, we develop a theory of semiprojectivity for real C*-algebras and also examine various definitions of low-rank for real C*-algebras.

We provide a compact exact representation for the distribution of the matrix elements of the Wishart-type random matrices A † A, for any finite number of rows and columns of A, without any large N approximations. In particular, we treat the case when the Wishart-type random matrix contains redundant, non-random information, which is a new result. This representation is of interest for a procedure for reconstructing the redundant information hidden in Wishart matrices, with potential applications to numerous models based on biological, social and artificial intelligence networks

Information geometry of density matrices and state estimation

Given a pure state vector |x) and a density matrix ρ-hat, the function p(x|ρ-hat)= defines a probability density on the space of pure states parameterised by density matrices. The associated Fisher-Rao information measure is used to define a unitary invariant Riemannian metric on the space of density matrices. An alternative derivation of the metric, based on square-root density matrices and trace norms, is provided. This is applied to the problem of quantum-state estimation. In the simplest case of unitary parameter estimation, new higher-order corrections to the uncertainty relations, applicable to general mixed states, are derived. (fast track communication)

What Would Humboldt Say: A Case of General Bildung in Vocational Education?

Directory of Open Access Journals (Sweden)

Ruhi Tyson

2016-12-01

Full Text Available A classic philosopher in the Bildung tradition, Humboldt argued that general Bildung was the opposite of specialist training (vocational education. This has been a matter of contention and the aim here is to revisit the issue through an empirical case study. In the vocational education biography of craft master Wolfgang B. he speaks about aspects of his education that have much in common with Humboldt’s ideal of general Bildung but transposed into the context of vocational education and training (VET. The concept of vocationalism (Beruflichkeit provides context to the present argument which is that the contrast Humboldt made is relevant but not in the sense of there being two categories of education (general and vocational but rather two expressions of pedagogy: one expansive and one exclusive. Furthermore, there are two versions of general or expansive Bildung present in the case. The conclusions are that empirical studies of vocational Bildung expand on the concept of Bildung, increase our understanding of how VET contains affordances of Bildung and of the curriculum-patterns related to this.

Full Text Available The regional development difference which has globally become a major problem even for developing countries is one of important problems of Turkey's economy. The regional dualism in the country's economy brings with many economic and social problems such as the immigration, the income inequality, the unplanned urbanization etc. The vocational schools established generally in localities less than ten thousand people contribute to remove the development difference of these localities by providing social and economic benefits as well as by training skilled staff to the locality where they are located. In this study we investigated the impact of vocational schools in the removal of the regional development difference and we made use of primary and secondary sources. Firstly, we scanned the literatures concerning this study, then we made survey with the students which study in Akören Ali Riza Ercan Vocational School. By taking the 5% significance level and the 5% margin of error into consideration in this study we used the SPSS for Windows statistics program in the evaluation of data taken as 317 students sample among the main body of 1,240 students. We tried to present solution proposals by studying the expectations and problems of the students as well as the contribution of the Akören Ali Riza Ercan Vocational School to the development of Akören district.

2014-01-01

Full Text Available In this study, we utilized a mandrel rotating collector consisting of two parallel, electrically conductive pieces of tape to fabricate aligned electrospun polycaprolactone/gelatin (PG and carbon nanotube/polycaprolactone/gelatin (PGC nanofibrous matrices. Furthermore, we examined the biological performance of the PGC nanofibrous and film matrices using an in vitro culture of RT4-D6P2T rat Schwann cells. Using cell adhesion tests, we found that carbon nanotube inhibited Schwann cell attachment on PGC nanofibrous and film matrices. However, the proliferation rates of Schwann cells were higher when they were immobilized on PGC nanofibrous matrices compared to PGC film matrices. Using western blot analysis, we found that NRG1 and P0 protein expression levels were higher for cells immobilized on PGC nanofibrous matrices compared to PG nanofibrous matrices. However, the carbon nanotube inhibited NRG1 and P0 protein expression in cells immobilized on PGC film matrices. Moreover, the NRG1 and P0 protein expression levels were higher for cells immobilized on PGC nanofibrous matrices compared to PGC film matrices. We found that the matrix topography and composition influenced Schwann cell behavior.

[Health status and health behaviour of apprentices in the first year of apprenticeship - first results of a survey in vocational training schools in Bielefeld].

Science.gov (United States)

Kaminski, A; Nauerth, A; Pfefferle, P I

2008-01-01

Apprentices form the major subgroup in adolescents aged between 16 and 25 years in Germany. Prospectively today's apprentices will display an important role within the society by being the backbone of the future middle class, a socio-economic group of high significance. However, there is little knowledge about the health of apprentices, a major determinant of economic and social capacity. A number of surveys has focussed on the health of adolescents, but these studies failed to provide specific data regarding the subgroup of apprentices. The aims of this study were to survey the health status and the health behaviour of apprentices in a large range of qualified jobs and to point out possible differences be-tween the occupantional fields and gender-specific items. These differences could serve as a starting point for the development of specially-tailored prevention and health promoting strategies in the dual vocational education system. 528 vocational first-year scholars aged between 16 to 25 years were enrolled in the study. A standardised questionnaire concerning life-style attitudes, (physical activity, smoking, alcolhol consumption, drug-abuse, the amount of sleep and dietary habits) was provided in different vocational school settings. The survey was conducted as a pilot-study in vocational schools of Bielefeld in spring 2005. The response rate was 100%. Health risk behaviours were common in apprentices. The percentage of smokers was higher than 50%, exceeding the average rate found in contemporary students. Physiological activity and sleeping quantity was significantly reduced compared to the period of regular scholarship, while drug-abuse slightly decreased. Gender, graduation and the vocational choice had an influence on the health behaviour of the apprentices. Depending on gender and the vocational choice, apprentices differed in their health risk behaviour and therefore require specially-tailored prevention activities. Health promotion and physical

A sensitive LC-MS/MS method for measurement of organophosphorus pesticides and their oxygen analogs in air sampling matrices.

Armstrong, Jenna L; Dills, Russell L; Yu, Jianbo; Yost, Michael G; Fenske, Richard A

2014-01-01

A rapid liquid chromatography tandem mass spectrometry (LC-MS/MS) method has been developed for determination of levels of the organophosphorus (OP) pesticides chlorpyrifos (CPF), azinphos methyl (AZM), and their oxygen analogs chlorpyrifos-oxon (CPF-O) and azinphos methyl-oxon (AZM-O) on common active air sampling matrices. XAD-2 resin and polyurethane foam (PUF) matrices were extracted with acetonitrile containing stable-isotope labeled internal standards (ISTD). Analysis was accomplished in Multiple Reaction Monitoring (MRM) mode, and analytes in unknown samples were identified by retention time (±0.1 min) and qualifier ratio (±30% absolute) as compared to the mean of calibrants. For all compounds, calibration linearity correlation coefficients were ≥0.996. Limits of detection (LOD) ranged from 0.15-1.1 ng/sample for CPF, CPF-O, AZM, and AZM-O on active sampling matrices. Spiked fortification recoveries were 78-113% from XAD-2 active air sampling tubes and 71-108% from PUF active air sampling tubes. Storage stability tests also yielded recoveries ranging from 74-94% after time periods ranging from 2-10 months. The results demonstrate that LC-MS/MS is a sensitive method for determining these compounds from two different matrices at the low concentrations that can result from spray drift and long range transport in non-target areas following agricultural applications. In an inter-laboratory comparison, the limit of quantification (LOQ) for LC-MS/MS was 100 times lower than a typical gas chromatography-mass spectrometry (GC-MS) method.

Nano-Fiber Reinforced Enhancements in Composite Polymer Matrices

Science.gov (United States)

Chamis, Christos C.

2009-01-01

Nano-fibers are used to reinforce polymer matrices to enhance the matrix dependent properties that are subsequently used in conventional structural composites. A quasi isotropic configuration is used in arranging like nano-fibers through the thickness to ascertain equiaxial enhanced matrix behavior. The nano-fiber volume ratios are used to obtain the enhanced matrix strength properties for 0.01,0.03, and 0.05 nano-fiber volume rates. These enhanced nano-fiber matrices are used with conventional fiber volume ratios of 0.3 and 0.5 to obtain the composite properties. Results show that nano-fiber enhanced matrices of higher than 0.3 nano-fiber volume ratio are degrading the composite properties.

At the biennial international WSC, young people (aged 18-to-23 years from over 60 countries demonstrate their skills in more than 40 trades. Individualized training for this competition is provided through the cooperation of vocational institutions (e.g., expert coaches, team leaders and competition panellists and industry (e.g., mentors, sponsors, materials, equipment. Semi-structured thematic interviews (N=51 were conducted in 2013 and 2014 with former Finnish WSC medal or diploma winners (n=18 who had since begun their working lives (1-to-15 years of work experience. Their employers (n=16 and colleagues (n=17 were also interviewed. Results showed that in addition to vocation-specific knowledge and skills, problem-solving skills, creativity, social skills and self-regulatory skills were acknowledged as the most significant elements of vocational expertise. The findings also indicated that formal vocational education combined with deliberate practice and training based on expert mentoring improved the long-term career progress and vocational expertise of the WSC achievers.

Reciprocal Associations between Educational Identity and Vocational Identity in Adolescence: A Three-wave Longitudinal Investigation.

Science.gov (United States)

Negru-Subtirica, Oana; Pop, Eleonora Ioana

2018-04-01

Education and vocation are core identity domains in adolescence. School is a normative social context in this developmental time frame and the formation of an educational identity is embedded in the goals that youth pursue in school. One of the main goals of education is to prepare young people for their future careers. Hence, educational identity should support the formation of vocational identity during adolescence. Considering the limited evidence on the longitudinal links between these two domain-specific identities, we conducted a three-wave investigation, testing the moderating role of age group, gender, and type of school. Participants (N = 1030; 59.3% female) were adolescents (M age  = 16.72 years, SD age  = 1.23, age range 14-19 years) who completed self-report measures of educational and vocational identity three times during an academic year. We underscored reciprocal associations between educational identity and vocational identity. The results indicate that strong educational commitments supported the formation of strong vocational commitments across time. Adolescents who were involved in the in-depth exploration of their educational choices also reported more vocational exploration during the school year. In turn, vocational identity processes also supported educational identity formation, especially the reconsideration of educational commitments. In terms of moderators, we underscored that vocational commitment making and vocational flexibility bolstered educational commitment only in early-to-middle adolescents. Educational in-depth exploration fostered the identification with vocational commitments only in girls. Educational reconsideration of commitment promoted vocational self-doubt only in adolescents attending work-bound high-schools. Implications for research and practice are discussed.

[Does Return to Work after Vocational Retraining Depend on Labour Market?

Science.gov (United States)

Hetzel, C; Streibelt, M

2016-10-01

Background: Studies about the impact of the labour market on return to work (RTW) after vocational retraining are contradictory. We examined if (1) RTW after vocational retraining depends on regional labour markets and if (2) the regional labour markets variance affects the influence of personal characteristics on RTW. Methods: The data consisted of the scientific use file (completed rehabilitation in the course of health insurance 2002-2009) of the German Federal Pension Insurance (51 626 persons of 7 year cohorts) and regional economic data (412 districts). Multilevel logistic regression models were used. Results: At the context level the logarithmic unemployment rate was the most relevant predictor. The RTW rate decreased with increasing unemployment rate, saturating at an unemployment rate of around 15%. Significant differences between the intervention types (integration, 1-year and 2-year vocational retraining programs) were observed. The effects of individual predictors were clearer with higher unemployment, e. g. education, individual unemployment, income and further vocational interventions prior to vocational retraining. Conclusion: We demonstrate that the success of vocational retraining depends on the regional labour market. Furthermore individual predictors show stronger effects on success with the context of "poor" labour markets. In addition to the existing evidence the regional unemployment rate should be taken into consideration in effectiveness research studies and benchmarking processes in quality assurance. © Georg Thieme Verlag KG Stuttgart · New York.

Joint Estimation of Multiple Precision Matrices with Common Structures.

Science.gov (United States)

Lee, Wonyul; Liu, Yufeng

Estimation of inverse covariance matrices, known as precision matrices, is important in various areas of statistical analysis. In this article, we consider estimation of multiple precision matrices sharing some common structures. In this setting, estimating each precision matrix separately can be suboptimal as it ignores potential common structures. This article proposes a new approach to parameterize each precision matrix as a sum of common and unique components and estimate multiple precision matrices in a constrained l 1 minimization framework. We establish both estimation and selection consistency of the proposed estimator in the high dimensional setting. The proposed estimator achieves a faster convergence rate for the common structure in certain cases. Our numerical examples demonstrate that our new estimator can perform better than several existing methods in terms of the entropy loss and Frobenius loss. An application to a glioblastoma cancer data set reveals some interesting gene networks across multiple cancer subtypes.

Students’ Preferred Characteristics of Learning Environments in Vocational Secondary Education

Directory of Open Access Journals (Sweden)

Ingeborg Placklé

2014-12-01

Full Text Available If teachers and teacher educators are willing to support the learning of students, it is important for them to learn what motivates students to engage in learning. Students have their own preferences on design characteristics of powerful learning environments in vocational education. We developed an instrument - the Inventory Powerful Learning Environments in Vocational Education - to measure students’ preferences on characteristics of powerful learning environments in vocational education. We investigated whether student preferences on the design of their learning environments are in line with what is described in the literature as beneficial for learning. Data of 544 students show that the preferences of students support most characteristics of PLEs in vocational education. Looking through the eyes of students, teachers have to challenge their students and encourage them to take their learning in their own hands. Adaptive learning support is needed. Remarkable, students do not prefer having reflective dialogues with teachers or peers.

The study was designed to discover examine the profile of metacognition of vocational high school student of the Machine Technology program that had high ability and field independent cognitive style in mathematical problem solving. The design of this study was exploratory research with a qualitative approach. This research was conducted at the Machine Technology program of the vocational senior high school. The result revealed that the high-ability student with field independent cognitive style conducted metacognition practices well. That involved the three types of metacognition activities, consisting of planning, monitoring, and evaluating at metacognition level 2 or aware use, 3 or strategic use, 4 or reflective use in mathematical problem solving. The applicability of the metacognition practices conducted by the subject was never at metacognition level 1 or tacit use. This indicated that the participant were already aware, capable of choosing strategies, and able to reflect on their own thinking before, after, or during the process at the time of solving mathematical problems.That was very necessary for the vocational high school student of Machine Technology program.

Under a collaborative interagency agreement between the U.S. Environmental Protection Agency and the U.S Department of Energy (DOE), the National Renewable Energy Laboratory (NREL) performed a series of in-depth analyses to characterize the on-road driving behavior including distributions of vehicle speed, idle time, accelerations and decelerations, and other driving metrics of medium- and heavy-duty vocational vehicles operating within the United States. As part of this effort, NREL researchers segmented U.S. medium- and heavy-duty vocational vehicle driving characteristics into three distinct operating groups or clusters using real world drive cycle data collected at 1 Hz and stored in NREL's Fleet DNA database. The Fleet DNA database contains millions of miles of historical real-world drive cycle data captured from medium- and heavy vehicles operating across the United States. The data encompass data from existing DOE activities as well as contributions from valued industry stakeholder participants. For this project, data captured from 913 unique vehicles comprising 16,250 days of operation were drawn from the Fleet DNA database and examined. The Fleet DNA data used as a source for this analysis has been collected from a total of 30 unique fleets/data providers operating across 22 unique geographic locations spread across the United States. This includes locations with topology ranging from the foothills of Denver, Colorado, to the flats of Miami, Florida. The range of fleets, geographic locations, and total number of vehicles analyzed ensures results that include the influence of these factors. While no analysis will be perfect without unlimited resources and data, it is the researchers understanding that the Fleet DNA database is the largest and most thorough publicly accessible vocational vehicle usage database currently in operation. This report includes an introduction to the Fleet DNA database and the data contained within, a presentation of the

Hypersymmetric functions and Pochhammers of 2×2 nonautonomous matrices

Directory of Open Access Journals (Sweden)

A. F. Antippa

2004-01-01

Full Text Available We introduce the hypersymmetric functions of 2×2 nonautonomous matrices and show that they are related, by simple expressions, to the Pochhammers (factorial polynomials of these matrices. The hypersymmetric functions are generalizations of the associated elementary symmetric functions, and for a specific class of 2×2 matrices, having a high degree of symmetry, they reduce to these latter functions. This class of matrices includes rotations, Lorentz boosts, and discrete time generators for the harmonic oscillators. The hypersymmetric functions are defined over four sets of independent indeterminates using a triplet of interrelated binary partitions. We work out the algebra of this triplet of partitions and then make use of the results in order to simplify the expressions for the hypersymmetric functions for a special class of matrices. In addition to their obvious applications in matrix theory, in coupled difference equations, and in the theory of symmetric functions, the results obtained here also have useful applications in problems involving successive rotations, successive Lorentz transformations, discrete harmonic oscillators, and linear two-state systems.

We designed and pilot-tested a group-based, work-related cognitive-behavioral therapy (WCBT) for unemployed individuals with social anxiety disorder (SAD). WCBT, delivered in a vocational service setting by vocational service professionals, aims to reduce social anxiety and enable individuals to seek, obtain, and retain employment. We compared WCBT to a vocational services as usual control condition (VSAU). Participants were unemployed, homeless, largely African American, vocational service-seeking adults with SAD (N = 58), randomized to receive either eight sessions of WCBT plus VSAU or VSAU alone and followed three months post-treatment. Multilevel modeling revealed significantly greater reductions in social anxiety, general anxiety, depression, and functional impairment for WCBT compared to VSAU. Coefficients for job search activity and self-efficacy indicated greater increases for WCBT. Hours worked per week in the follow-up period did not differ between the groups, but small sample size and challenges associated with measuring work hours may have contributed to this finding. Overall, the results of this study suggest that unemployed persons with SAD can be effectively treated with specialized work-related CBT administered by vocational service professionals. Future testing of WCBT with a larger sample, a longer follow-up period, and adequate power to assess employment outcomes is warranted. Copyright © 2014 Elsevier Ltd. All rights reserved.

This research design is a true experimental using post-test only. The population is students from one vocational high school in North Sulawesi. Sample of this research was year 11 students consisting of two classes class A (27 students) and class B (27 students). The instrument used in collecting data is tests. The results showed that the mean of the experimental group (36.99) statistically describes the students’ improvement in pronouncing English words in which have been compared by result of the tobserved (2.897) exceed tcritical (1.943) at the level of significance 0.05. It means that there is a significant difference between the mean score of experimental group and control group regarding students’ English pronunciation. This then supports the claim that ‘rejects’ Ho and ‘accept’ Ha. Based on the result, it could be concluded that the direct method is considered effective in improving students’ English pronunciation.

2011-01-01

Policy debates about the balance of vocational and general education programs focus on the school-to-work transition. But with rapid technological change, gains in youth employment from vocational education may be offset by less adaptability and thus diminished employment later in life. To test our main hypothesis that any relative labor-market advantage of vocational education decreases with age, we employ a difference-in-differences approach that compares employment rates across different a...

Partitioning sparse rectangular matrices for parallel processing

Energy Technology Data Exchange (ETDEWEB)

Kolda, T.G.

1998-05-01

The authors are interested in partitioning sparse rectangular matrices for parallel processing. The partitioning problem has been well-studied in the square symmetric case, but the rectangular problem has received very little attention. They will formalize the rectangular matrix partitioning problem and discuss several methods for solving it. They will extend the spectral partitioning method for symmetric matrices to the rectangular case and compare this method to three new methods -- the alternating partitioning method and two hybrid methods. The hybrid methods will be shown to be best.

2009-01-01

We solve the loop equations to all orders in 1/N 2 , for the Chain of Matrices matrix model (with possibly an external field coupled to the last matrix of the chain). We show that the topological expansion of the free energy, is, like for the 1 and 2-matrix model, given by the symplectic invariants of [19]. As a consequence, we find the double scaling limit explicitly, and we discuss modular properties, large N asymptotics. We also briefly discuss the limit of an infinite chain of matrices (matrix quantum mechanics).

We specify some initial assumptions that guarantee rapid refinement of a rough initial approximation to the inverse of a Cauchy-like matrix, by mean of our new modification of Newton`s iteration, where the input, output, and all the auxiliary matrices are represented with their short generators defined by the associated scaling operators. The computations are performed fast since they are confined to operations with short generators of the given and computed matrices. Because of the known correlations among various structured matrices, the algorithm is immediately extended to rapid refinement of rough initial approximations to the inverses of Vandermonde-like, Chebyshev-Vandermonde-like and Toeplitz-like matrices, where again, the computations are confined to operations with short generators of the involved matrices.

Agricultural matrices affect ground ant assemblage composition inside forest fragments.

Directory of Open Access Journals (Sweden)

Diego Santana Assis

Full Text Available The establishment of agricultural matrices generally involves deforestation, which leads to fragmentation of the remaining forest. This fragmentation can affect forest dynamics both positively and negatively. Since most animal species are affected, certain groups can be used to measure the impact of such fragmentation. This study aimed to measure the impacts of agricultural crops (matrices on ant communities of adjacent lower montane Atlantic rainforest fragments. We sampled nine forest fragments at locations surrounded by different agricultural matrices, namely: coffee (3 replicates; sugarcane (3; and pasture (3. At each site we installed pitfall traps along a 500 m transect from the interior of the matrix to the interior of the fragment (20 pitfall traps ~25 m apart. Each transect was partitioned into four categories: interior of the matrix; edge of the matrix; edge of the fragment; and interior of the fragment. For each sample site, we measured ant species richness and ant community composition within each transect category. Ant richness and composition differed between fragments and matrices. Each sample location had a specific composition of ants, probably because of the influence of the nature and management of the agricultural matrices. Species composition in the coffee matrix had the highest similarity to its corresponding fragment. The variability in species composition within forest fragments surrounded by pasture was greatest when compared with forest fragments surrounded by sugarcane or, to a lesser extent, coffee. Functional guild composition differed between locations, but the most representative guild was 'generalist' both in the agricultural matrices and forest fragments. Our results are important for understanding how agricultural matrices act on ant communities, and also, how these isolated forest fragments could act as an island of biodiversity in an 'ocean of crops'.

Education for work: Reflections towards a theory of vocational education

Science.gov (United States)

Corson, David J.

1985-12-01

By integrating aspects of a philosophy of work and a sociology of work, this article draws conclusions relevant to framing a theory of vocational education. `Education for work' is accepted in this paper as the common central meaning of the term `vocational education'. The two concepts, `education' and `work', are first examined separately: `work' is seen to include recreational and occupational work, while occupational work is seen to fall on a continuum ranging from constrained to unconstrained occupational work. `Education' and `training' are distinguished. After a discussion of the conceptual links which might be drawn between `education' and `work', recommendations are made about the aims, the place, and the curriculum of vocational education within the general institution of education.

MALDI matrices for low molecular weight compounds: an endless story?

Science.gov (United States)

Calvano, Cosima Damiana; Monopoli, Antonio; Cataldi, Tommaso R I; Palmisano, Francesco

2018-04-23

Since its introduction in the 1980s, matrix-assisted laser desorption/ionization mass spectrometry (MALDI MS) has gained a prominent role in the analysis of high molecular weight biomolecules such as proteins, peptides, oligonucleotides, and polysaccharides. Its application to low molecular weight compounds has remained for long time challenging due to the spectral interferences produced by conventional organic matrices in the low m/z window. To overcome this problem, specific sample preparation such as analyte/matrix derivatization, addition of dopants, or sophisticated deposition technique especially useful for imaging experiments, have been proposed. Alternative approaches based on second generation (rationally designed) organic matrices, ionic liquids, and inorganic matrices, including metallic nanoparticles, have been the object of intense and continuous research efforts. Definite evidences are now provided that MALDI MS represents a powerful and invaluable analytical tool also for small molecules, including their quantification, thus opening new, exciting applications in metabolomics and imaging mass spectrometry. This review is intended to offer a concise critical overview of the most recent achievements about MALDI matrices capable of specifically address the challenging issue of small molecules analysis.

Hierarchical Matrices Method and Its Application in Electromagnetic Integral Equations

Directory of Open Access Journals (Sweden)

Han Guo

2012-01-01

Full Text Available Hierarchical (H- matrices method is a general mathematical framework providing a highly compact representation and efficient numerical arithmetic. When applied in integral-equation- (IE- based computational electromagnetics, H-matrices can be regarded as a fast algorithm; therefore, both the CPU time and memory requirement are reduced significantly. Its kernel independent feature also makes it suitable for any kind of integral equation. To solve H-matrices system, Krylov iteration methods can be employed with appropriate preconditioners, and direct solvers based on the hierarchical structure of H-matrices are also available along with high efficiency and accuracy, which is a unique advantage compared to other fast algorithms. In this paper, a novel sparse approximate inverse (SAI preconditioner in multilevel fashion is proposed to accelerate the convergence rate of Krylov iterations for solving H-matrices system in electromagnetic applications, and a group of parallel fast direct solvers are developed for dealing with multiple right-hand-side cases. Finally, numerical experiments are given to demonstrate the advantages of the proposed multilevel preconditioner compared to conventional “single level” preconditioners and the practicability of the fast direct solvers for arbitrary complex structures.

2003-07-01

The present study was undertaken to evaluate the effect of different insoluble and erodable wax-lipid based materials and their content level on the release profile of drug from matrix systems. Matrix tablets of theophylline were prepared using carnauba wax, bees wax, stearic acid, cetyl alcohol, cetostearyl alcohol and glyceryl monostearate as rate-retarding agents by direct compression process. The release of theophylline from these hydrophobic matrices was studied over 8-hours in buffer media of pH 6.8. Statistically significant difference was found among the drug release profile from different matrices. The release kinetics was found to be governed by the type and content of hydrophobic materials in the matrix. At lower level of wax matrices (25%), a potential burst release was observed with all the materials being studied. Bees wax could not exert any sustaining action while an extensive burst release was found with carnauba wax at this hydrophobic load. Increasing the concentration of fat-wax materials significantly decreased the burst effect of drug from the matrix. At higher hydrophobic level (50% of the matrix), the rate and extent of drug release was significantly reduced due to increased tortuosity and reduced porosity of the matrix. Cetostearyl alcohol imparted the strongest retardation of drug release irrespective of fat-wax level. Numerical fits indicate that the Higuchi square root of time model was the most appropriate one for describing the release profile of theophylline from hydrophobic matrices. The release mechanism was also explored and explained with biexponential equation. Application of this model indicates that Fickian or case I kinetics is the predominant mechanism of drug release from these wax-lipid matrices. The mean dissolution time (MDT) was calculated for all the formulations and the highest MDT value was obtained with cetostearyl matrix. The greater sustaining activity of cetostearyl alcohol can be attributed to some level of

Implementation of vocational learning in accordance with the 2013 curriculum must meet the criteria, one of which is learning to be consistent with advances in technology and information. Technology-based learning in vocational commonly referred to as E-Learning, online (in the network) and WBL (Web-Based Learning). Facts on the ground indicate that based learning technology and information on Vocational High School of Building Engineering is still not going well. The purpose of this research is to know: advantages and disadvantages of learning with E-Learning, conformity of learning with E-Learning with characteristics of students on Vocational High School of Building Engineering and effective learning method based on E-Learning for students on Vocational High School of Building Engineering. Research done by literature method, get the following conclusion as follow: the advantages of E-Learning is learning can be done anywhere and anytime, efficient in accessing materials and tasks, ease of communication and discussion; while the shortage is the need for additional costs for good internet access and lack of social interaction between teachers and students. E-learning is appropriate to basic knowledge competencies, and not appropriate at the level of advanced competencies and skills. Effective E-Learning Based Learning Method on Vocational High School of Building Engineering is a Blended method that is a mix between conventional method and e-learning.

In this work, we define the Pell-Jacobsthal-Slyvester sequence and the Jacobsthal-Pell-Slyvester sequence by using the Slyvester matrices which are obtained from the characteristic polynomials of the Pell and Jacobsthal sequences and then, we study the sequences defined modulo m. Also, we obtain the cyclic groups and the semigroups from the generating matrices of these sequences when read modulo m and then, we derive the relationships among the orders of the cyclic groups and the periods of the sequences. Furthermore, we redefine Pell-Jacobsthal-Slyvester sequence and the Jacobsthal-Pell-Slyvester sequence by means of the elements of the groups and then, we examine them in the finite groups.

Quantitative mass spectrometry of unconventional human biological matrices

Dutkiewicz, Ewelina P.; Urban, Pawel L.

2016-10-01

The development of sensitive and versatile mass spectrometric methodology has fuelled interest in the analysis of metabolites and drugs in unconventional biological specimens. Here, we discuss the analysis of eight human matrices-hair, nail, breath, saliva, tears, meibum, nasal mucus and skin excretions (including sweat)-by mass spectrometry (MS). The use of such specimens brings a number of advantages, the most important being non-invasive sampling, the limited risk of adulteration and the ability to obtain information that complements blood and urine tests. The most often studied matrices are hair, breath and saliva. This review primarily focuses on endogenous (e.g. potential biomarkers, hormones) and exogenous (e.g. drugs, environmental contaminants) small molecules. The majority of analytical methods used chromatographic separation prior to MS; however, such a hyphenated methodology greatly limits analytical throughput. On the other hand, the mass spectrometric methods that exclude chromatographic separation are fast but suffer from matrix interferences. To enable development of quantitative assays for unconventional matrices, it is desirable to standardize the protocols for the analysis of each specimen and create appropriate certified reference materials. Overcoming these challenges will make analysis of unconventional human biological matrices more common in a clinical setting. This article is part of the themed issue 'Quantitative mass spectrometry'.

Assessing vocational outcome expectancy in individuals with serious mental illness: a factor-analytic approach.

2017-07-04

Self-determination theory (SDT) and self-efficacy theory (SET) can be used to conceptualize self-determined motivation to engage in mental health and vocational rehabilitation (VR) services and to predict recovery. To incorporate SDT and SET as a framework for vocational recovery, developing and validating SDT/SET measures in vocational rehabilitation is warranted. Outcome expectancy is an important SDT/SET variable affecting rehabilitation engagement and recovery. The purpose of this study was to validate the Vocational Outcome Expectancy Scale (VOES) for use within the SDT/SET vocational recovery framework. One hundred and twenty-four individuals with serious mental illness (SMI) participated in this study. Measurement structure of the VOES was evaluated using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Both EFA and CFA results supported a two-factor structure: (a) positive outcome expectancy, and (b) negative outcome expectancy. The internal consistency reliability coefficients for both factors were acceptable. In addition, positive outcome expectancy correlated stronger than negative outcome expectancy with other SDT/SET constructs in the expected directions. The VOES is a brief, reliable and valid instrument for assessing vocational outcome expectancy in individuals with SMI that can be integrated into SDT/SET as a vocational rehabilitation engagement and recovery model in psychiatric rehabilitation.

Profile of cognitive problems in schizophrenia and implications for vocational functioning.

Science.gov (United States)

Tan, Bhing-Leet

2009-08-01

This literature review attempts to profile specific areas of cognition that have shown unique and consistent evidence of dysfunction among people with schizophrenia. In addition, their impact on vocational functioning is illustrated, so as to highlight the importance of managing these cognitive difficulties in vocational rehabilitation. Literature search was carried out on seven key cognitive domains identified by the National Institute of Mental Health in the USA. Their impact on vocational function was also reviewed. It is found that attention, declarative and working memory, reasoning, problem-solving and social cognition are areas of impairment that have great impact on vocational functioning. Attention and memory problems affect learning of new work tasks. Executive function is particularly crucial in determining supported and open employment outcomes, as executive dysfunction cannot be easily compensated. Lastly, social cognition plays a major role in determining the success of workplace social exchanges. Occupational therapists need to have a good understanding of the profile of cognitive problems among people with schizophrenia, in order to tailor our intervention according to their cognitive strengths and difficulties. Several cognitive remediation strategies and programs have been designed specifically for people with mental illness. Equipping ourselves with skills in conducting such programs will augment our expertise in vocational rehabilitation.

Flexible Bayesian Dynamic Modeling of Covariance and Correlation Matrices

KAUST Repository

Lan, Shiwei

2017-11-08

Modeling covariance (and correlation) matrices is a challenging problem due to the large dimensionality and positive-definiteness constraint. In this paper, we propose a novel Bayesian framework based on decomposing the covariance matrix into variance and correlation matrices. The highlight is that the correlations are represented as products of vectors on unit spheres. We propose a variety of distributions on spheres (e.g. the squared-Dirichlet distribution) to induce flexible prior distributions for covariance matrices that go beyond the commonly used inverse-Wishart prior. To handle the intractability of the resulting posterior, we introduce the adaptive $\\\\Delta$-Spherical Hamiltonian Monte Carlo. We also extend our structured framework to dynamic cases and introduce unit-vector Gaussian process priors for modeling the evolution of correlation among multiple time series. Using an example of Normal-Inverse-Wishart problem, a simulated periodic process, and an analysis of local field potential data (collected from the hippocampus of rats performing a complex sequence memory task), we demonstrated the validity and effectiveness of our proposed framework for (dynamic) modeling covariance and correlation matrices.

Full Text Available The vocational training in Spain has reached a late formalization in the educational system. This situation is explained by the economical contexts thatevolve from the agricultural sector to the industrial development of certain zones, which are those who have a better network of vocational schools. In this article three levels of analysis are addressed: the first one, related to the politics and educational legislation, in order to notice the process of formalization; the second one, focused on the relevance of the Church on this sector and, the third one is the role played by the Union Organization during the Franco's regime. In this way, the intervention of the different agents who have contributed to the development of the vocational training in Spain remains clear up to the General Law of Education of 1970.

2013-07-01

Full Text Available The issue of the quality of vocational education, school, teaching and learning of students should be in the interests of all participants in the education process. The quality of secondary school is the critical element in enhancing the attractiveness of vocational education in Slovakia. Finding an offcial scale that would provide such a information in Slovakia is unfortunately impossible. There is no system for evaluating the quality of vocational education and training (VET at vocational schools. There are no clearly defined criterias, rules or any standards. Speaking of an assessing the level of quality of vocational education on the base of existing outcomes in formal education such as monitoring, final exams, graduation exams is resulting in one-sided evaluation and does not address the systematic coherence and complexivity of this issue. An essential step os to create a functional system of evaluation of VET in Slovakia. The article describes importance of VET which can play a central role in preparing young people for work, developing the skills of adults and responding to the labour market needs of the economy and presents the project Model of the quality evaluation of vocational education and training at secondary vocational schools in Slovakia that is currently ongoing on many secondary vocational schools in western Slovakia and Austria. The aim of the project is to develop and apply an open, flexible and adaptable quality management system. The article not only presents indicators for evaluation but also the way how can be evaluated each of them. The effort of this project is also to create specialized portal with support services that provide transparent, clear and specific information from this area of interest. The introduction of the evaluation framework, the selection of indicators that take established criteria into consideration and assembling of the scale is therefore more than relevant and required

Full Text Available The trend of globalization affects the frame of tourism education. The rising competition conditions make the quality of tourism services more important. One of the most important elements of the quality of tourism services is the theorical and practical competence of labor. From the other point of view, cookery education has an important value in tourism education. Since the school year of 2005-2006, the moduler vocational education system has been followed and the cookery education has been given within the frame of National Cookery Vocational Qualification with the support of the EU in Türkiye. The objective of this study is to find out the theorical and practical competence levels of the cookery students within the frame of National Cookery Vocational Qualification. To serve this purpose, a questionnaire survey was conducted for 1014 cookery students of Hotels and Vocational High Schools in Türkiye and the theorical and practical competence levels of the students have been analyzed. According to the findings of the study, the students are more competenced on; “self care, self preparation for work, cooking kinds of pasta, cooking kinds of pilafs, preparing kinds of salads, preparing vegetable garnishes, cooking kinds of soups” subjects than the other subjects. From the other point of view, the students are less competenced on; “designating of daily portion quantities of food groups, cooking special kinds of international soups, cooking offal food particular to Turkish cuisine, preparing stewed fruit particular to Turkish cuisine and preparing seafood” than the other subjects.

Associative Yang-Baxter equation for quantum (semi-)dynamical R-matrices

International Nuclear Information System (INIS)

Sechin, Ivan; Zotov, Andrei

2016-01-01

In this paper we propose versions of the associative Yang-Baxter equation and higher order R-matrix identities which can be applied to quantum dynamical R-matrices. As is known quantum non-dynamical R-matrices of Baxter-Belavin type satisfy this equation. Together with unitarity condition and skew-symmetry it provides the quantum Yang-Baxter equation and a set of identities useful for different applications in integrable systems. The dynamical R-matrices satisfy the Gervais-Neveu-Felder (or dynamical Yang-Baxter) equation. Relation between the dynamical and non-dynamical cases is described by the IRF (interaction-round-a-face)-Vertex transformation. An alternative approach to quantum (semi-)dynamical R-matrices and related quantum algebras was suggested by Arutyunov, Chekhov, and Frolov (ACF) in their study of the quantum Ruijsenaars-Schneider model. The purpose of this paper is twofold. First, we prove that the ACF elliptic R-matrix satisfies the associative Yang-Baxter equation with shifted spectral parameters. Second, we directly prove a simple relation of the IRF-Vertex type between the Baxter-Belavin and the ACF elliptic R-matrices predicted previously by Avan and Rollet. It provides the higher order R-matrix identities and an explanation of the obtained equations through those for non-dynamical R-matrices. As a by-product we also get an interpretation of the intertwining transformation as matrix extension of scalar theta function likewise R-matrix is interpreted as matrix extension of the Kronecker function. Relations to the Gervais-Neveu-Felder equation and identities for the Felder’s elliptic R-matrix are also discussed.

Asymmetric correlation matrices: an analysis of financial data

Science.gov (United States)

Livan, G.; Rebecchi, L.

2012-06-01

We analyse the spectral properties of correlation matrices between distinct statistical systems. Such matrices are intrinsically non-symmetric, and lend themselves to extend the spectral analyses usually performed on standard Pearson correlation matrices to the realm of complex eigenvalues. We employ some recent random matrix theory results on the average eigenvalue density of this type of matrix to distinguish between noise and non-trivial correlation structures, and we focus on financial data as a case study. Namely, we employ daily prices of stocks belonging to the American and British stock exchanges, and look for the emergence of correlations between two such markets in the eigenvalue spectrum of their non-symmetric correlation matrix. We find several non trivial results when considering time-lagged correlations over short lags, and we corroborate our findings by additionally studying the asymmetric correlation matrix of the principal components of our datasets.

No Eigenvalues Outside the Limiting Support of Generally Correlated Gaussian Matrices

Kammoun, Abla; Alouini, Mohamed-Slim

2016-01-01

This paper investigates the behaviour of the spectrum of generally correlated Gaussian random matrices whose columns are zero-mean independent vectors but have different correlations, under the specific regime where the number of their columns and that of their rows grow at infinity with the same pace. Following the approach proposed in [1], we prove that under some mild conditions, there is no eigenvalue outside the limiting support of generally correlated Gaussian matrices. As an outcome of this result, we establish that the smallest singular value of these matrices is almost surely greater than zero. From a practical perspective, this control of the smallest singular value is paramount to applications from statistical signal processing and wireless communication, in which this kind of matrices naturally arise.

Vocational education and employment over the life course using a new measure of occupational specificity.

Science.gov (United States)

Forster, Andrea G; Bol, Thijs

2018-02-01

Vocational education is seen as beneficial for the labor market allocation of young people. However, recent studies point to disadvantages later in the life course, where the specific skills that are obtained from vocational education decrease employability. This paper re-evaluates this hypothesis for the Netherlands with an improved measure for the vocational specificity of educational programs, utilizing both vertical (level) and horizontal (field) information on education. More specifically, we use a gradual measure for the linkage strength between education and occupation to predict employment over the life course. Using data from the national Dutch labor force surveys, we show that there is considerable heterogeneity in occupational specificity within the categories of vocational and general educational programs that is masked when using a dichotomous classification of general versus vocational education. In the life course analyses we find that the large early benefits of having vocational education disappear later in the career and turn into a small disadvantage before retirement. Copyright © 2017.

Improving STD testing behavior among high-risk young adults by offering STD testing at a vocational school

Directory of Open Access Journals (Sweden)

Hoebe Christian JPA

2011-09-01

Full Text Available Abstract Background Chlamydia trachomatis infection (CT is the most prevalent bacterial STD. Sexually active adolescents and young adults are the main risk group for CT. However, STD testing rates in this group are low since exposed individuals may not feel at risk, owing-at least in part-to the infection's largely asymptomatic nature. Designing new testing environments that are more appealing to young people who are most at risk of acquiring chlamydia can be an important strategy to improve overall testing rates. Here we evaluate the effect of a school-based sexual health program conducted among vocational school students, aiming to obtain better access for counseling and enhance students' STD testing behavior. Methods Adolescents (median age 19 years attending a large vocational school were provided with sexual health education. Students filled in a questionnaire measuring CT risk and were offered STD testing. Using univariate and multivariate analysis, we assessed differences between men and women in STD-related risk behavior, sexual problems, CT testing behavior and determinants of CT testing behavior. Results Of 345 participants, 70% were female. Of the 287 sexually active students, 75% were at high risk for CT; one third of women reported sexual problems. Of sexually active participants, 61% provided a self-administered specimen for STD testing. Independent determinants for testing included STD related symptoms and no condom use. All CT diagnoses were in the high-CT-risk group. In the high-risk group, STD testing showed an increased uptake, from 27% (previous self-reported test to 65% (current test. CT prevalence was 5.7%. Conclusions Vocational school students are a target population for versatile sexual health prevention. When provided with CT testing facilities and education, self selection mechanisms seemed to increase CT testing rate dramatically in this high-CT-risk population expressing sexual problems. Considering the relative ease

Safety Valve or Sinkhole? Vocational Schooling in South Africa

As an alternative to traditional academic schooling, vocational schooling in South Africa may serve as a safety valve for students encountering difficulty in the transition from school to work. Yet if ineffective, vocational schooling could also be a sinkhole, offering little chance for success on the labor market.

Uncertainty analysis in comparative NAA applied to geological and biological matrices

Zahn, Guilherme S.; Ticianelli, Regina B.; Lange, Camila N.; Favaro, Deborah I.T.; Figueiredo, Ana M.G.

2015-01-01

Comparative nuclear activation analysis is a multielemental primary analytical technique that may be used in a rather broad spectrum of matrices with minimal-to-none sample preprocessing. Although the total activation of a chemical element in a sample depends on a rather large set of parameters, when the sample is irradiated together with a well-known comparator, most of these parameters are crossed out and the concentration of that element can be determined simply by using the activities and masses of the comparator and the sample, the concentration of this chemical element in the sample, the half-life of the formed radionuclide and the time between counting the sample and the comparator. This simplification greatly reduces not only the calculations required, but also the uncertainty associated with the measurement; nevertheless, a cautious analysis must be carried out in order to make sure all relevant uncertainties are properly treated, so that the final result can be as representative of the measurement as possible. In this work, this analysis was performed for geological matrices, where concentrations of the interest nuclides are rather high, but so is the density and average atomic number of the sample, as well as for a biological matrix, in order to allow for a comparison. The results show that the largest part of the uncertainty comes from the activity measurements and from the concentration of the comparator, and that while the influence of time-related terms in the final uncertainty can be safely neglected, the uncertainty in the masses may be relevant under specific circumstances.

We look for all weak bases that lead to texture zeroes in the quark mass matrices and contain a minimal number of parameters in the framework of the standard model. Since there are ten physical observables, namely, six nonvanishing quark masses, three mixing angles and one CP phase, the maximum number of texture zeroes in both quark sectors is altogether nine. The nine zero entries can only be distributed between the up- and down-quark sectors in matrix pairs with six and three texture zeroes or five and four texture zeroes. In the weak basis where a quark mass matrix is nonsingular and has six zeroes in one sector, we find that there are 54 matrices with three zeroes in the other sector, obtainable through right-handed weak basis transformations. It is also found that all pairs composed of a nonsingular matrix with five zeroes and a nonsingular and nondecoupled matrix with four zeroes simply correspond to a weak basis choice. Without any further assumptions, none of these pairs of up- and down-quark mass matrices has physical content. It is shown that all non-weak-basis pairs of quark mass matrices that contain nine zeroes are not compatible with current experimental data. The particular case of the so-called nearest-neighbour-interaction pattern is also discussed.

Between General Education and Vocational Training or What Claims Future has on Us

Directory of Open Access Journals (Sweden)

Dušana Findeisen

1996-12-01

Full Text Available Dušana Findeisen deals with the relationship between general education and vocational training in the future. White qualifications needed on the labour market in 15 years are not easily predictable, it is possible to predict with certainty only the kind of people needed and which basic qualifications are to be included among the educational goals to be attained by school population and adults. Among basic qualifications or competencies are ranging: managing thinking processes, communication competence, competence of playing an active role in community, attitude towards environment. Further, the author points out the need for different didactic processes and evaluation ensuring a balance of various elements of education and "producing" well balanced people. General education should penetrate "narrow gauge" vocational training of adults, since enterprises do not search only for good professionals but also for people able to adapt and to develop along with them.

Basal Cell Carcinoma With Matrical Differentiation: Clinicopathologic, Immunohistochemical, and Molecular Biological Study of 22 Cases.

Basal cell carcinoma (BCC) with matrical differentiation is a fairly rare neoplasm, with about 30 cases documented mainly as isolated case reports. We studied a series of this neoplasm, including cases with an atypical matrical component, a hitherto unreported feature. Lesions coded as BCC with matrical differentiation were reviewed; 22 cases were included. Immunohistochemical studies were performed using antibodies against BerEp4, β-catenin, and epithelial membrane antigen (EMA). Molecular genetic studies using Ion AmpliSeq Cancer Hotspot Panel v2 by massively parallel sequencing on Ion Torrent PGM were performed in 2 cases with an atypical matrical component (1 was previously subjected to microdissection to sample the matrical and BCC areas separately). There were 13 male and 9 female patients, ranging in age from 41 to 89 years. Microscopically, all lesions manifested at least 2 components, a BCC area (follicular germinative differentiation) and areas with matrical differentiation. A BCC component dominated in 14 cases, whereas a matrical component dominated in 4 cases. Matrical differentiation was recognized as matrical/supramatrical cells (n=21), shadow cells (n=21), bright red trichohyaline granules (n=18), and blue-gray corneocytes (n=18). In 2 cases, matrical areas manifested cytologic atypia, and a third case exhibited an infiltrative growth pattern, with the tumor metastasizing to a lymph node. BerEP4 labeled the follicular germinative cells, whereas it was markedly reduced or negative in matrical areas. The reverse pattern was seen with β-catenin. EMA was negative in BCC areas but stained a proportion of matrical/supramatrical cells. Genetic studies revealed mutations of the following genes: CTNNB1, KIT, CDKN2A, TP53, SMAD4, ERBB4, and PTCH1, with some differences between the matrical and BCC components. It is concluded that matrical differentiation in BCC in most cases occurs as multiple foci. Rare neoplasms manifest atypia in the matrical areas

Full Text Available Although several studies have recently assessed direct self-injurious behavior (D-SIB among adolescents, it is still understudied in adolescents attending vocational schools: an educational setting generally associated with lower socioeconomic status. After extending the “Saving and Empowering Young Lives in Europe” (SEYLE project to a vocational school population, we examined their D-SIB and life event characteristics compared to the high school population. SEYLE’s Hungarian randomly selected high school sample (N = 995 was completed with a randomly selected vocational school sample (N = 140 in Budapest, Hungary. Participants aged 14–17 years completed the SEYLE project’s self-administered questionnaires. D-SIB lifetime prevalence was significantly higher (29.4% in the vocational school group compared to the high school group (17.2% (Χ2(1 = 12.231, p< 0.001. D-SIB was associated with suicidal ideation in the vocational school group. Different life events were more frequent in the high school than in the vocational school group, and associations between D-SIB and life events differed in the vocational school group compared to the high school group. In conclusion, vocational school students are a vulnerable population with a higher prevalence of D-SIB compared to high school students. Life events and their association with D-SIB also differ in vocational school students compared to high school students. Taking all these into account might contribute to prevention/intervention designed for this population.

Dirac Matrices and Feynman’s Rest of the Universe

Directory of Open Access Journals (Sweden)

Young S. Kim

2012-10-01

Full Text Available There are two sets of four-by-four matrices introduced by Dirac. The first set consists of fifteen Majorana matrices derivable from his four γ matrices. These fifteen matrices can also serve as the generators of the group SL(4, r. The second set consists of ten generators of the Sp(4 group which Dirac derived from two coupled harmonic oscillators. It is shown possible to extend the symmetry of Sp(4 to that of SL(4, r if the area of the phase space of one of the oscillators is allowed to become smaller without a lower limit. While there are no restrictions on the size of phase space in classical mechanics, Feynman’s rest of the universe makes this Sp(4-to-SL(4, r transition possible. The ten generators are for the world where quantum mechanics is valid. The remaining five generators belong to the rest of the universe. It is noted that the groups SL(4, r and Sp(4 are locally isomorphic to the Lorentz groups O(3, 3 and O(3, 2 respectively. This allows us to interpret Feynman’s rest of the universe in terms of space-time symmetry.

Dynamical correlations for circular ensembles of random matrices

International Nuclear Information System (INIS)

Nagao, Taro; Forrester, Peter

2003-01-01

Circular Brownian motion models of random matrices were introduced by Dyson and describe the parametric eigenparameter correlations of unitary random matrices. For symmetric unitary, self-dual quaternion unitary and an analogue of antisymmetric Hermitian matrix initial conditions, Brownian dynamics toward the unitary symmetry is analyzed. The dynamical correlation functions of arbitrary number of Brownian particles at arbitrary number of times are shown to be written in the forms of quaternion determinants, similarly as in the case of Hermitian random matrix models

Quantum Algorithms for Weighing Matrices and Quadratic Residues

van Dam, Wim

2000-01-01

In this article we investigate how we can employ the structure of combinatorial objects like Hadamard matrices and weighing matrices to device new quantum algorithms. We show how the properties of a weighing matrix can be used to construct a problem for which the quantum query complexity is ignificantly lower than the classical one. It is pointed out that this scheme captures both Bernstein & Vazirani's inner-product protocol, as well as Grover's search algorithm. In the second part of the ar...

Applicability of non-invasively collected matrices for human biomonitoring

Directory of Open Access Journals (Sweden)

Nickmilder Marc

2009-03-01

Full Text Available Abstract With its inclusion under Action 3 in the Environment and Health Action Plan 2004–2010 of the European Commission, human biomonitoring is currently receiving an increasing amount of attention from the scientific community as a tool to better quantify human exposure to, and health effects of, environmental stressors. Despite the policy support, however, there are still several issues that restrict the routine application of human biomonitoring data in environmental health impact assessment. One of the main issues is the obvious need to routinely collect human samples for large-scale surveys. Particularly the collection of invasive samples from susceptible populations may suffer from ethical and practical limitations. Children, pregnant women, elderly, or chronically-ill people are among those that would benefit the most from non-invasive, repeated or routine sampling. Therefore, the use of non-invasively collected matrices for human biomonitoring should be promoted as an ethically appropriate, cost-efficient and toxicologically relevant alternative for many biomarkers that are currently determined in invasively collected matrices. This review illustrates that several non-invasively collected matrices are widely used that can be an valuable addition to, or alternative for, invasively collected matrices such as peripheral blood sampling. Moreover, a well-informed choice of matrix can provide an added value for human biomonitoring, as different non-invasively collected matrices can offer opportunities to study additional aspects of exposure to and effects from environmental contaminants, such as repeated sampling, historical overview of exposure, mother-child transfer of substances, or monitoring of substances with short biological half-lives.

Polymer Percolation Threshold in Multi-Component HPMC Matrices Tablets

Directory of Open Access Journals (Sweden)

Maryam Maghsoodi

2011-06-01

Full Text Available Introduction: The percolation theory studies the critical points or percolation thresholds of the system, where onecomponent of the system undergoes a geometrical phase transition, starting to connect the whole system. The application of this theory to study the release rate of hydrophilic matrices allows toexplain the changes in release kinetics of swellable matrix type system and results in a clear improvement of the design of controlled release dosage forms. Methods: In this study, the percolation theory has been applied to multi-component hydroxypropylmethylcellulose (HPMC hydrophilic matrices. Matrix tablets have been prepared using phenobarbital as drug,magnesium stearate as a lubricant employing different amount of lactose and HPMC K4M as a fillerandmatrix forming material, respectively. Ethylcelullose (EC as a polymeric excipient was also examined. Dissolution studies were carried out using the paddle method. In order to estimate the percolation threshold, the behaviour of the kinetic parameters with respect to the volumetric fraction of HPMC at time zero, was studied. Results: In both HPMC/lactose and HPMC/EC/lactose matrices, from the point of view of the percolation theory, the optimum concentration for HPMC, to obtain a hydrophilic matrix system for the controlled release of phenobarbital is higher than 18.1% (v/v HPMC. Above 18.1% (v/v HPMC, an infinite cluster of HPMC would be formed maintaining integrity of the system and controlling the drug release from the matrices. According to results, EC had no significant influence on the HPMC percolation threshold. Conclusion: This may be related to broad functionality of the swelling hydrophilic matrices.

Efficient metabolism of fatty acids during anaerobic waste digestion requires development of consortia that include "fatty acid consuming H(2) producing bacteria" and methanogenic bacteria. The objective of this research was to optimize methanogenesis from fatty acids by evaluating a variety of support matrices for use in maintaining efficient syntrophic-methanogenic consortia. Tested matrices included clays (montmorillonite and bentonite), glass beads (106 and 425-600mum), microcarriers (cytopore, cytodex, cytoline, and cultispher; conventionally employed for cultivation of mammalian cell lines), BioSep beads (powdered activated carbon), and membranes (hydrophilic; nylon, polysulfone, and hydrophobic; teflon, polypropylene). Data obtained from headspace methane (CH(4)) analyses as an indicator of anaerobic carbon cycling efficiency indicated that material surface properties were important in maintenance and functioning of the anaerobic consortia. Cytoline yielded significantly higher CH(4) than other matrices as early as in the first week of incubation. 16S rRNA gene sequence analysis from crushed cytoline matrix showed the presence of Syntrophomonas spp. (butyrate oxidizing syntrophs) and Syntrophobacter spp. (propionate oxidizing syntrophs), with Methanosaeta spp. (acetate utilizing methanogen), and Methanospirillum spp. (hydrogen utilizing methanogen) cells. It is likely that the more hydrophobic surfaces provided a suitable surface for adherence of cells of syntrophic-methanogenic consortia. Cytoline also appeared to protect entrapped consortia from air, resulting in rapid methanogenesis after aerial exposure. Our study suggests that support matrices can be used in anaerobic digestors, pre-seeded with immobilized or entrapped consortia on support matrices, and may be of value as inoculant-adsorbents to rapidly initiate or recover proper system functioning following perturbation.

Glaeser, H.

2008-01-01

Internationally agreed Integral Test Facility (ITF) matrices for validation of realistic thermal hydraulic system computer codes were established. ITF development is mainly for Pressurised Water Reactors (PWRs) and Boiling Water Reactors (BWRs). A separate activity was for Russian Pressurised Water-cooled and Water-moderated Energy Reactors (WWER). Firstly, the main physical phenomena that occur during considered accidents are identified, test types are specified, and test facilities suitable for reproducing these aspects are selected. Secondly, a list of selected experiments carried out in these facilities has been set down. The criteria to achieve the objectives are outlined. In this paper some specific examples from the ITF matrices will also be provided. The matrices will be a guide for code validation, will be a basis for comparisons of code predictions performed with different system codes, and will contribute to the quantification of the uncertainty range of code model predictions. In addition to this objective, the construction of such a matrix is an attempt to record information which has been generated around the world over the last years, so that it is more accessible to present and future workers in that field than would otherwise be the case.

In compressed sensing, one takes samples of an N-dimensional vector using an matrix A, obtaining undersampled measurements . For random matrices with independent standard Gaussian entries, it is known that, when is k-sparse, there is a precisely determined phase transition: for a certain region in the (,)-phase diagram, convex optimization typically finds the sparsest solution, whereas outside that region, it typically fails. It has been shown empirically that the same property—with the ...

Two-mode Gaussian density matrices and squeezing of photons

International Nuclear Information System (INIS)

Tucci, R.R.

1992-01-01

In this paper, the authors generalize to 2-mode states the 1-mode state results obtained in a previous paper. The authors study 2-mode Gaussian density matrices. The authors find a linear transformation which maps the two annihilation operators, one for each mode, into two new annihilation operators that are uncorrelated and unsqueezed. This allows the authors to express the density matrix as a product of two 1-mode density matrices. The authors find general conditions under which 2-mode Gaussian density matrices become pure states. Possible pure states include the 2-mode squeezed pure states commonly mentioned in the literature, plus other pure states never mentioned before. The authors discuss the entropy and thermodynamic laws (Second Law, Fundamental Equation, and Gibbs-Duhem Equation) for the 2-mode states being considered
