Full Text Available Expanding grain sorghum [Sorghum bicolor (L. Moench] production northward from southeastern Colorado is thought to be limited by shorter growing seasons due to lower temperatures and earlier frost dates. This study used a simulation model for predicting crop phenology (PhenologyMMS to estimate the probability of reaching physiological maturity before the first fall frost for a variety of agronomic practices in northeastern Colorado. Physiological maturity for seven planting dates (1 May to 12 June, four seedbed moisture conditions affecting seedling emergence (from Optimum to Planted in Dust, and three maturity classes (Early, Medium, and Late were simulated using historical weather data from nine locations for both irrigated and dryland phenological parameters. The probability of reaching maturity before the first frost was slightly higher under dryland conditions, decreased as latitude, longitude, and elevation increased, planting date was delayed, and for later maturity classes. The results provide producers with estimates of the reliability of growing grain sorghum in northeastern Colorado.

["Scholar officials": thoughts on the involvement of professional nurses in the political process].

A growing number of nurses are concerned with / participate in public affairs, politics, and policymaking processes. In particular, nursing leaders are actively leveraging their collective power to create interdisciplinary alliances aimed at encouraging the media and government to confront key nursing issues and implement healthcare reform. This article highlights the political participation and policy-making process to address the meaning and essence of politics, politics and nursing, training and strategies of public affairs and political participation, the shift from academia to health policy, and facilitation of important health policies. It is hoped that nurses may appropriately use their status and influence to actively participate in political campaigns and the policymaking process. By using their professional knowledge and skills, nurses may not only protect patient safety and public health but also facilitate nursing professional development and promote the professional image of nursing.

In September 2014, the AGU Board of Directors approved two initiatives to help the Earth and space sciences community address the growing challenges accompanying the increasing size and complexity of data. These initiatives are: 1) Data Science Credentialing: development of a continuing education and professional certification program to help scientists in their careers and to meet growing responsibilities and requirements around data science; and 2) Data Management Maturity (DMM) Model: development and implementation of a data management maturity model to assess process maturity against best practices, and to identify opportunities in organizational data management processes. Each of these has been organized within AGU as an Editorial Board and both Boards have held kick off meetings. The DMM model Editorial Board will recommend strategies for adapting and deploying a DMM model to the Earth and space sciences create guidance documents to assist in its implementation, and provide input on a pilot appraisal process. This presentation will provide an overview of progress to date in the DMM model Editorial Board and plans for work to be done over the upcoming year.

2014-02-01

This study utilizes a prospective design to examine the interaction of recent rape/attempted rape with individual differences in thought suppression on increases in disordered eating symptoms during late adolescence/emerging adulthood. Thought suppression is the attempt to suppress unwanted thoughts. We propose that emerging adult women who have experienced recent rape/attempted rape and tend to use thought suppression as a coping mechanism are at risk for increases in disordered eating. 319 women completed the Eating Disorder Examination Questionnaire, the Sexual Experiences Survey, the Childhood Trauma Questionnaire, and the White Bear Thought Suppression Inventory in their first month of college and three months later. The experience of recent rape/attempted rape in the three months prior to the assessment accounted for unique variance in disordered eating at Time 2. Levels of thought suppression assessed at Time 1 significantly moderated the influence of recent rape/attempted rape on disordered eating at Time 2.

Professional confidence: a concept analysis.

Science.gov (United States)

Holland, Kathlyn; Middleton, Lyn; Uys, Leana

2012-03-01

Professional confidence is a concept that is frequently used and or implied in occupational therapy literature, but often without specifying its meaning. Rodgers's Model of Concept Analysis was used to analyse the term "professional confidence". Published research obtained from a federated search in four health sciences databases was used to inform the concept analysis. The definitions, attributes, antecedents, and consequences of professional confidence as evidenced in the literature are discussed. Surrogate terms and related concepts are identified, and a model case of the concept provided. Based on the analysis, professional confidence can be described as a dynamic, maturing personal belief held by a professional or student. This includes an understanding of and a belief in the role, scope of practice, and significance of the profession, and is based on their capacity to competently fulfil these expectations, fostered through a process of affirming experiences. Developing and fostering professional confidence should be nurtured and valued to the same extent as professional competence, as the former underpins the latter, and both are linked to professional identity.

Second-to-Last Thoughts

Trimble, Virginia L.

2016-06-01

You can’t really prepare an abstract of a concluding-remarks talk, but having spent 19 years, 8 months as a full time student (Sept. 1948, Toluca Lake Grammar School kindergarten to April 1968 Caltech Ph.D.), most of the ensuing 48 years as a teacher, and about 51 years as some sort of astronomer, I find myself woefully ignorant of astronomy education and therefore well prepared to bring a fresh and vacant mind to the ideas presented by our colleagues here. Several thoughts, however, intrude. First, as Cecilia Payne Gaposchkin said, “a woman should do astronomy only if nothing else will satisfy her, for nothing else is what she will get.” Make that “person” and “science” and it still carries much truth. Second, it is better to be a professional astronomer and an amateur alto than the converse. And third, it is better to be a professional dentist and an amateur astronomer than the converse. This, I think, leaves room for all of us to work in areas that we find attractive and that we turn out to be reasonably good at. The latter is at least as important as the former. There is a great deal of pleasure to be found as a second-rate singer or artist, but not, I hope, as a lousy astronomer or teacher.

Physicians have long provided care free of charge or at a reduced rate as a professional courtesy to other physicians and their families. We conducted a stratified national mail survey to assess the extent to which this practice has changed in recent years. Using the American Medical Association's 1991 master list of physicians, we selected a random sample of 4800 practicing physicians from 12 direct-care specialties. These physicians were asked about their current policy and opinions regarding professional courtesy. Of the 2224 respondents, 2127 (96 percent) offered professional courtesy, defined as providing free or discounted health care to physicians and their families. Psychiatrists were less likely to offer professional courtesy than physicians in any of the other specialties (80 percent vs. 91 to 99 percent, P courtesy included billing only the insurance company (75 percent), providing care at no charge (49 percent), and giving a partial discount (23 percent). Twenty-three percent of the respondents reported that they had changed their policy regarding professional courtesy since starting to practice. Among those who had changed their policy, the most common changes were to increase the practice of billing only the insurance company (67 percent) and to provide care at no charge less often (58 percent). The majority of physicians responding to the survey thought that professional courtesy solidified bonds between physicians (79 percent) and was sound business practice (62 percent); 12 percent believed that it was too expensive to offer free or discounted care as a professional courtesy, and 14 percent thought that the practice had negative effects on the physician-patient interaction. Our survey of physicians involved in direct patient care indicates that, with the exception of psychiatrists, almost all American physicians offer free or discounted care as a professional courtesy and support the practice.

Little is known about how positive phenomena can support resettlement of refugees in a new country. The aim of this study was to examine the hopeful thinking in a group of West African quota refugees at arrival and after 6 years in Sweden and compare these thoughts to the views of resettlement support professionals. The primary study population comprised 56 adult refugees and 13 resettlement professionals. Qualitative data were collected from the refugees by questionnaires on arrival and 6 years later. Data were collected from the resettlement professionals by interview about 3 years after arrival of the refugees. Snyder's cognitive model of hope was used to inform the comparative data analyses. Hopes regarding education were in focus for the refugees shortly after arrival, but thoughts on family reunion were central later in the resettlement process. During the later stages of the resettlement process, the unresponsiveness of the support organization to the family reunion problem became as issue for the refugees. The professionals reported a complex mix of "silent agency thoughts" underlying the local resettlement process as a contributing reason for this unresponsiveness. Hopes regarding education and family reunion were central in the resettlement of West African refugees in Sweden. These thoughts were not systematically followed up by the support organization; possibly the resources for refugees were not fully released. More studies are needed to further investigate the motivational factors underpinning host community support of refugees' hopes and plans.

The aim of this study was to investigate the association between dental and skeletal maturity. Digital panoramic radiographs and lateral skull cephalograms of 302 patients (134 boys and 168 girls, ranging from 8 to 16 years of age) were examined. Dental maturity was assessed by calcification stages of the mandibular canines, first and second premolars, and second molars, whereas skeletal maturity was estimated by the cervical vertebral maturation (CVM) stages. The Spearman rank-order correlation coefficient was used to measure the association between CVM stage and dental calcification stage of individual teeth. The mean chronologic age of girls was significantly lower than that of boys in each CVM stage. The Spearman rank-order correlation coefficients between dental maturity and cervical vertebral maturity ranged from 0.391 to 0.582 for girls and from 0.464 to 0.496 for boys (P cervical vertebral maturation stage. The development of the mandibular second molar in females and that of the mandibular canine in males had the strongest correlations with cervical vertebral maturity. Therefore, it is practical to consider the relationship between dental and skeletal maturity when planning orthodontic treatment. Copyright © 2010 Mosby, Inc. All rights reserved.

Negative career thoughts are cognitive barriers that interfere with an individual's career decision-making and successful career development. The current study examined the effect of rational-emotive behavior therapy (REBT) on negative career thoughts of students in technical colleges in Nigeria. The study utilized a pretest-posttest control group design. One hundred and seventy-three participants from technical colleges in the Southeast zone of the country completed a measure of career thoughts at pretest, posttreatment, and follow-up: the College Students' Career Thoughts Scale. An REBT career program manual guided the intervention for 12 weeks. Data collected were analyzed using repeated-measures analysis of variance, chi-square, and t-test. Results show that the negative career thoughts of the REBT group participants were significantly reduced relative to a waitlist control group at the end of the intervention. Follow-up tests conducted after three months and six months revealed that the significant decrease in negative career thoughts of the REBT group participants was sustained. The outcomes of the current study suggest that REBT is an invaluable group therapy for assisting college students in overcoming negative thoughts associated with career choice and decision. It would be helpful if further longitudinal evaluation were implemented in Nigeria and in other countries to evaluate whether and how an REBT-based program can improve vocational maturity and vocational identity of technical college students.

High spectral and spatial resolution data from the Moon Mineralogy Mapper (M3) instrument on Chandrayaan-1 are used to investigate in detail changes in the optical properties of lunar materials accompanying space weathering. Three spectral parameters were developed and used to quantify spectral effects commonly thought to be associated with increasing optical maturity: an increase in spectral slope ("reddening"), a decrease in albedo ("darkening"), and loss of spectral contrast (decrease in absorption band depth). Small regions of study were defined that sample the ejecta deposits of small fresh craters that contain relatively crystalline (immature) material that grade into local background (mature) soils. Selected craters are small enough that they can be assumed to be of constant composition and thus are useful for evaluating trends in optical maturity. Color composites were also used to identify the most immature material in a region and show that maturity trends can also be identified using regional soil trends. The high resolution M3 data are well suited to quantifying the spectral changes that accompany space weathering and are able to capture subtle spectral variations in maturity trends. However, the spectral changes that occur as a function of maturity were observed to be dependent on local composition. Given the complexity of space weathering processes, this was not unexpected but poses challenges for absolute measures of optical maturity across diverse lunar terrains.

Full Text Available In recent years there has been an increasing interest in maturity models in management-related disciplines; which reflects a growing recognition that becoming more mature and having a model to guide the route to maturity can help organisations in managing major transformational change. Lean Construction (LC is an increasingly important improvement approach that organisations seek to embed. This study explores how to apply the maturity models to LC. Hence the attitudes, opinions and experiences of key industry informants with high levels of knowledge of LC were investigated. To achieve this, a review of maturity models was conducted, and data for the analysis was collected through a sequential process involving three methods. First a group interview with seven key informants. Second a follow up discussion with the same individuals to investigate some of the issues raised in more depth. Third an online discussion held via LinkedIn in which members shared their views on some of the results. Overall, we found that there is a lack of common understanding as to what maturity means in LC, though there is general agreement that the concept of maturity is a suitable one to reflect the path of evolution for LC within organisations.

Dehydrin expression in seeds and maturation drying: a paradigm change.

Science.gov (United States)

Radwan, A; Hara, M; Kleinwächter, M; Selmar, D

2014-09-01

Dehydrins are well known for being expressed in leaves during the course of developmental processes as well as under drought stress, being part of the protective machinery. Moreover, in seed physiology, dehydrins are classified as late embryogenesis-related proteins (LEA protein), where they are thought to be responsible for persistence and longevity of seeds. Although both topics are a focus of modern plant biology, a direct linkage between these both areas is generally lacking. Based on an alignment of the chain of events, this paper will help to generate understanding that the occurrence of dehydrins in maturing seeds and leaves suffering drought stress is part of the same basic principle: basic principle: dehydrins are expressed in response to water shortage. Unfortunately, the related developmental process in seeds, i.e. maturation drying, has not been adequately considered as a part of this process. As a corresponding implication, the chain of events must be adjusted: the differences in dehydrin expression in orthodox, intermediate and recalcitrant seeds could be directly attributed to the occurrence or absence of maturation drying. The differences in dehydrin expression in orthodox, intermediate and recalcitrant seeds, and thus the differences in longevity, could be attributed to the occurrence or absence of a maturation drying. © 2014 German Botanical Society and The Royal Botanical Society of the Netherlands.

To examine the significance of thought-action fusion (TAF) and thought suppression tendencies, the present study obtained pre- and post-treatment questionnaire data on these constructs in a sample of OCD patients (n=24) and non-OCD anxiety patients (n=20). Results indicate that TAF and suppression are correlated with severity of psychopathology. Yet, the associations between TAF and psychopathology are not typical for OCD, but do also occur in other anxiety disorders (e.g., panic disorder, post traumatic stress disorder, and social phobia). As well, mean scores on the TAF and thought suppression measures dropped significantly from pre- to post-treatment, indicating that TAF and thought suppression are susceptible to change during psychotherapy.

1999-06-01

A review of studies which investigated drawings of the ideal man and the occupational aspirations of boys (ages 11-18 years) from several countries indicated that becoming a professional athlete was a popular but unrealistic aspiration for many adolescent boys. Boys who were athletes and nonathletes from diverse ethnic groups and nationalities dreamed of becoming professional athletes. In two additional studies in the United States of America, adolescents were asked why they thought boys most often selected professional athlete as a possible future occupation. Adolescents perceived professional athletes as rich, famous, and glorified. Enhancement of status and financial gain were ranked as more important than the desire to play sports.

Are temperate mature forests buffered from invasive lianas?

Science.gov (United States)

Pavlovic, Noel B.; Leicht-Young, Stacey A.

2011-01-01

Mature and old-growth forests are often thought to be buffered against invasive species due to low levels of light and infrequent disturbance. Lianas (woody vines) and other climbing plants are also known to exhibit lower densities in older forests. As part of a larger survey of the lianas of the southern Lake Michigan region in mature and old-growth forests, the level of infestation by invasive lianas was evaluated. The only invasive liana detected in these surveys was Celastrus orbiculatus Thunb. (Celastraceae). Although this species had only attached to trees and reached the canopy in a few instances, it was present in 30% of transects surveyed, mostly as a component of the ground layer. Transects with C. orbiculatus had higher levels of soil potassium and higher liana richness than transects without. In contrast, transects with the native C. scandens had higher pH, sand content, and soil magnesium and lower organic matter compared to transects where it was absent. Celastrus orbiculatus appears to be a generalist liana since it often occurs with native lianas. Celastrus orbiculatus poses a substantial threat to mature forests as it will persist in the understory until a canopy gap or other disturbance provides the light and supports necessary for it to ascend to the canopy and damage tree species. As a result, these forests should be monitored by land managers so that C. orbiculatus eradication can occur while invasions are at low densities and restricted to the ground layer.

With the migration of human beings, advances of agricultural sciences, evolution of planting patterns and global warming, soybeans have expanded to both tropical and high-latitude cold regions (HCRs). Unlike other regions, HCRs have much more significant and diverse photoperiods and temperature conditions over seasons or across latitudes, and HCR soybeans released there show rich diversity in maturity traits. However, HCR soybeans have not been as well classified into maturity groups (MGs) as other places. Therefore, it is necessary to identify MGs in HCRs and to genotype the maturity loci. Local varieties were collected from the northern part of Northeast China and the far-eastern region of Russia. Maturity group reference (MGR) soybeans of MGs MG000, MG00, and MG0 were used as references during field experiments. Both local varieties and MGR soybeans were planted for two years (2010-2011) in Heihe (N 50°15', E 127°27', H 168.5 m), China. The days to VE (emergence), R1 (beginning bloom) and R7 (beginning maturity) were recorded and statistically analyzed. Furthermore, some varieties were further genotyped at four molecularly-identified maturity loci E1, E2, E3 and E4. The HCR varieties were classified into MG0 or even more early-maturing. In Heihe, some varieties matured much earlier than MG000, which is the most early-maturing known MG, and clustered into a separate group. We designated the group as MG0000, following the convention of MGs. HCR soybeans had relatively stable days to beginning bloom from emergence. The HCR varieties diversified into genotypes of E1, E2, E3 and E4. These loci had different effects on maturity. HCRs diversify early-maturing MGs of soybean. MG0000, a new MG that matures much earlier than known MGs, was developed. HCR soybean breeding should focus more on shortening post-flowering reproductive growth. E1, E2, E3, and E4 function differentially.

To establish the most effective approach and type of educational intervention for health professional students, to enable them to maintain a professionally safe online presence. This was a qualitative, multinational, multi-institutional, multiprofessional study. Practical considerations (availability of participants) led us to use a combination of focus groups and individual interviews, strengthening our findings by triangulating our method of data collection. The study gathered data from 57 nursing, medical and paramedical students across four sites in three countries (Aotearoa/New Zealand, Australia and Wales). A content analysis was conducted to clarify how and why students used Facebook and what strategies they thought might be useful to ensure professional usage. A series of emergent codes were examined and a thematic analysis undertaken from which key themes were crystallized. The results illuminated the ways in which students use social networking sites (SNS). The three key themes to emerge from the data analysis were negotiating identities, distancing and risks. Students expressed the wish to have material about professional safety on SNS taught to them by authoritative figures to explain "the rules" as well as by peers to assist with practicalities. Our interactive research method demonstrated the transformative capacity of the students working in groups. Our study supports the need for an educational intervention to assist health professional students to navigate SNS safely and in a manner appropriate to their future roles as health professionals. Because health professional students develop their professional identity throughout their training, we suggest that the most appropriate intervention incorporate small group interactive sessions from those in authority, and from peers, combined with group work that facilitates and enhances the students' development of a professional identity.

Psychological effects of thought acceleration.

Science.gov (United States)

Pronin, Emily; Jacobs, Elana; Wegner, Daniel M

2008-10-01

Six experiments found that manipulations that increase thought speed also yield positive affect. These experiments varied in both the methods used for accelerating thought (i.e., instructions to brainstorm freely, exposure to multiple ideas, encouragement to plagiarize others' ideas, performance of easy cognitive tasks, narration of a silent video in fast-forward, and experimentally controlled reading speed) and the contents of the thoughts that were induced (from thoughts about money-making schemes to thoughts of five-letter words). The results suggested that effects of thought speed on mood are partially rooted in the subjective experience of thought speed. The results also suggested that these effects can be attributed to the joy-enhancing effects of fast thinking (rather than only to the joy-killing effects of slow thinking). This work is inspired by observations of a link between "racing thoughts" and euphoria in cases of clinical mania, and potential implications of that observed link are discussed.

Thoughts in flight: automation use and pilots' task-related and task-unrelated thought.

Science.gov (United States)

Casner, Stephen M; Schooler, Jonathan W

2014-05-01

The objective was to examine the relationship between cockpit automation use and task-related and task-unrelated thought among airline pilots. Studies find that cockpit automation can sometimes relieve pilots of tedious control tasks and afford them more time to think ahead. Paradoxically, automation has also been shown to lead to lesser awareness. These results prompt the question of what pilots think about while using automation. A total of 18 airline pilots flew a Boeing 747-400 simulator while we recorded which of two levels of automation they used. As they worked, pilots were verbally probed about what they were thinking. Pilots were asked to categorize their thoughts as pertaining to (a) a specific task at hand, (b) higher-level flight-related thoughts (e.g.,planning ahead), or (c) thoughts unrelated to the flight. Pilots' performance was also measured. Pilots reported a smaller percentage of task-at-hand thoughts (27% vs. 50%) and a greater percentage of higher-level flight-related thoughts (56% vs. 29%) when using the higher level of automation. However, when all was going according to plan, using either level of automation, pilots also reported a higher percentage of task-unrelated thoughts (21%) than they did when in the midst of an unsuccessful performance (7%). Task-unrelated thoughts peaked at 25% when pilots were not interacting with the automation. Although cockpit automation may provide pilots with more time to think, it may encourage pilots to reinvest only some of this mental free time in thinking flight-related thoughts. This research informs the design of human-automation systems that more meaningfully engage the human operator.

Scrambled Eggs: Apoptotic Cell Clearance by Non-Professional Phagocytes in the Drosophila Ovary

2017-11-01

Full Text Available For half of a century, it has been known that non-professional phagocytes, such as fibroblasts, endothelial, and epithelial cells, are capable of efferocytosis (engulfment of apoptotic cells. Non-professional phagocytes differ from professional phagocytes in the range and efficiency of engulfment. Much of the recognition and underlying signaling machinery between non-professional and professional phagocytes is the same, but it is not known how the engulfment capacity of non-professional phagocytes is controlled. Moreover, the signaling networks involved in cell corpse recognition, engulfment, and phagosome maturation are only partially understood. The Drosophila ovary provides an excellent system to investigate the regulation of phagocytic activity by epithelial cells, a major class of non-professional phagocytes. During Drosophila oogenesis, mid-stage egg chambers undergo apoptosis of the germline in response to nutrient deprivation. Epithelial follicle cells then undergo major cell shape changes and concomitantly engulf the germline material. Our previous work has established that Draper and the integrin α-PS3/β-PS heterodimer are required in follicle cells for germline cell clearance. In addition, we have characterized phagosome maturation pathways, and found that the JNK pathway amplifies the engulfment response. In this review, we discuss recent advances on the interplay between engulfment pathways in the follicular epithelium for cell clearance in the Drosophila ovary. We also provide a comparison to apoptotic cell clearance mechanisms in C. elegans and mammals, illustrating strong conservation of efferocytosis mechanisms by non-professional phagocytes.

Anterior-Posterior Connectivity within the Default Mode Network Increases During Maturation.

Washington, Stuart D; VanMeter, John W

The default mode network (DMN) supports self-referential thought processes important for successful socialization including: theory-of-mind, episodic memory, and prospection. Connectivity between DMN's nodes, which are distributed between the frontal, temporal, and parietal lobes, change with age and may continue changing into adulthood. We have previously explored the maturation of functional connections in the DMN as they relate to autism spectrum disorder (ASD) in children 6 to 18 years of age. In this chapter, we refine our earlier study of DMN functional maturation by focusing on the development of inter-nodal connectivity in a larger pool of typically developing people 6 to 25 years of age (mean = 13.22 years ± 5.36 s.d.; N = 36; 42% female). Correlations in BOLD activity (Fisher's Z) between ROIs revealed varying strengths of functional connectivity between regions, the strongest of which was between the left and right inferior parietal lobules or IPLs (Z = 0.62 ± 0.25 s.d.) and the weakest of which was between the posterior cingulate cortex (PCC) and right middle temporal gyrus or MTG (Z = 0.06 ± 0.22 s.d.). Further, connectivity between two pairs of DMN nodes significantly increased as a quadratic function of age ( p maturational trajectory.

Dense core vesicles (DCVs) are thought to be generated at the late Golgi apparatus as immature DCVs, which subsequently undergo a maturation process through clathrin-mediated membrane remodeling events. This maturation process is required for efficient processing of neuropeptides within DCVs and for removal of factors that would otherwise interfere with DCV release. Previously, we have shown that the GTPase, RAB-2, and its effector, RIC-19, are involved in DCV maturation in Caenorhabditis elegans motoneurons. In rab-2 mutants, specific cargo is lost from maturing DCVs and missorted into the endosomal/lysosomal degradation route. Cargo loss could be prevented by blocking endosomal delivery. This suggests that RAB-2 is involved in retention of DCV components during the sorting process at the Golgi-endosomal interface. To understand how RAB-2 activity is regulated at the Golgi, we screened for RAB-2-specific GTPase activating proteins (GAPs). We identified a potential RAB-2 GAP, TBC-8, which is exclusively expressed in neurons and which, when depleted, shows similar DCV maturation defects as rab-2 mutants. We could demonstrate that RAB-2 binds to its putative GAP, TBC-8. Interestingly, TBC-8 also binds to the RAB-2 effector, RIC-19. This interaction appears to be conserved as TBC-8 also interacted with the human ortholog of RIC-19, ICA69. Therefore, we propose that a dynamic ON/OFF cycling of RAB-2 at the Golgi induced by the GAP/effector complex is required for proper DCV maturation.

Bad thoughts: Brazilian women's responses to mothering while experiencing postnatal depression.

Santos, Hudson Pires Oliveira; Sandelowski, Margarete; Gualda, Dulce Maria Rosa

2014-06-01

this study explores Brazilian women's experiences of mothering of their infants while experiencing postnatal depression. a cross-language qualitative descriptive design. the sample was composed of 15 women diagnosed with postnatal depression in a psychiatric institute in São Paulo, Brazil. Open-ended interviews were conducted and the data underwent thematic analysis. 13 women worried that harm would come to their infants. Seven of these women self-identified as potential sources of harm, with two women physically hurting their infants. The remaining six women worried about unknown agents, such as disease, hurting their infants. In response to these bad thoughts, women mothered their infants in one of four ways: (1) transferred care, completely delegating this task to family members; (2) shared care, asking family members to share the responsibility; (3) sole care, having to look after their infants by themselves because they had no available family support; (4) and smother care, being hyper-vigilant, constantly watching their infants and not trusting infant care to anyone else. the bad thoughts influenced the women's adaptation to mothering their infants. Health professionals should assess these thoughts early in the postnatal period and the women's mothering responses for the protection of mother and child. © 2013 Published by Elsevier Ltd.

Full Text Available The paper analyzes the features of professional “self-image” of a person as a cognitive component of professional self-concept in the structure of the professional identity of an individual as a conscious indicator of belonging to a specific profession, which is determined by personally significant professional activity and is expressed through professional distinguishing signs. An important aspect when considering the substantial characteristics of a professional “self-image” is the relation of the categories of “Self” and professional self-consciousness as a multi-level representations of a man about himself as a professional in the unity of three components: cognitive, affective and behavioral. We reveal the influence of professional standard content for the content of professional “self-image” and rise of their content association in the process of professional development and professional maturity of a subject. We present the author’s position on defining a vector of personal development in a professional environment as a result of harmonization of professional positions of “real self” and “ideal self”. Structurally professional “self-image” of a person is revealed through four interrelated components: socio-perceptual, cognitive, emotional and evaluative, and behavioral.

Full Text Available Normal 0 false false false IN X-NONE X-NONE MicrosoftInternetExplorer4 Project management has been generally known and increasingly used by many organizations to gain competitive advantage. In this context, many studies have proposed maturity models to evaluate how project management knowledge has been deployed effectively and efficiently in organization. As a developing country, Indonesia needs many development projects managed by government and private companies in different industries. Here, a study to assess project management maturity level in Indonesian businesses may bring insight about current business practices, which is important to speed up country development and business sustainability.  Adapting the Project Management Maturity Model (ProMMM, a survey instrument has been developed and applied to professionals from Jakarta and surrounding area.  The result of analysis shows that construction and primary industry have a higher maturity level compare to manufacturing and services.  It is to be noted, however, that the level of project management understanding is low across industries.  This indicates that more quality project management training or certification is required to improve overall project management knowledge in Indonesia. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

Critical Thoughts About the Core Entrustable Professional Activities in Undergraduate Medical Education.

Science.gov (United States)

Krupat, Edward

2018-03-01

The Core Entrustable Professional Activities for Entering Residency (Core EPAs) have taken a strong hold on undergraduate medical education (UME). This Perspective questions their value added and considers the utility of the Core EPAs along two separate dimensions: (1) the ways they change the content and focus of the goals of UME; and (2) the extent to which entrustable professional activity (EPA)-based assessment conforms to basic principles of measurement theory as practiced in the social sciences. Concerning content and focus, the author asks whether the 13 Core EPAs frame UME too narrowly, putting competencies into the background and overlooking certain aspirational, but important and measurable, objectives of UME. The author also discusses the unevenness of EPAs in terms of their breadth and their developmental status as core activities. Regarding measurement and assessment, the author raises concerns that the EPA metric introduces layers of inference that may cause distortions and hinder accuracy and rater agreement. In addition, the use of weak anchors and multidimensional scales is also of concern. The author concludes with a proposal for reframing the Core EPAs and Accreditation Council for Graduate Medical Education competencies into broadly defined sets of behaviors, referred to as "Tasks of Medicine," and calls for the development of a systematic and longitudinal research agenda. The author asserts that "slowing down when you should" applies to medical education as well as patient care, and calls for a reevaluation of the Core EPAs before further commitment to them.

The current study examined the effects of a psychoeducational intervention designed to target thought-action fusion (TAF) on TAF, thought suppression, and responsibility cognitions. 139 undergraduate students (25 male; 114 female) who were relatively high in TAF with respect to their peers served as participants. Immediately following intervention, individuals who had received psychoeducation regarding TAF reported significantly lower morality TAF scores than individuals who had received psychoeducation regarding thoughts in general and individuals in the control group. At the two-week follow-up assessment, the likelihood TAF scores of those who had received psychoeducation regarding TAF were significantly lower than those of the control group. In addition, the group that received psychoeducation regarding TAF was the only group that did not experience a significant increase in thought suppression from baseline to post-intervention, and was also the only group to experience an increase in both frequency of and belief in low-responsibility thoughts from baseline to follow-up. Implications are discussed. (c) 2010 Elsevier Ltd. All rights reserved.

From intrusive to oscillating thoughts.

Science.gov (United States)

Peirce, Anne Griswold

2007-10-01

This paper focused on the possibility that intrusive thoughts (ITs) are a form of an evolutionary, adaptive, and complex strategy to prepare for and resolve stressful life events through schema formation. Intrusive thoughts have been studied in relation to individual conditions, such as traumatic stress disorder and obsessive-compulsive disorder. They have also been documented in the average person experiencing everyday stress. In many descriptions of thought intrusion, it is accompanied by thought suppression. Several theories have been put forth to describe ITs, although none provides a satisfactory explanation as to whether ITs are a normal process, a normal process gone astray, or a sign of pathology. There is also no consistent view of the role that thought suppression plays in the process. I propose that thought intrusion and thought suppression may be better understood by examining them together as a complex and adaptive mechanism capable of escalating in times of need. The ability of a biological mechanism to scale up in times of need is one hallmark of a complex and adaptive system. Other hallmarks of complexity, including self-similarity across scales, sensitivity to initial conditions, presence of feedback loops, and system oscillation, are also discussed in this article. Finally, I propose that thought intrusion and thought suppression are better described together as an oscillatory cycle.

Our data indicate that the terminal maturation and enucleation of human primitive RBCs occurs in fir...

Popper's Thought Experiment Reinvestigated

Science.gov (United States)

Richardson, Chris; Dowling, Jonathan

2012-02-01

Karl Popper posed an interesting thought experiment in 1934. With it, he meant to question the completeness of quantum mechanics. He claimed that the notion of quantum entanglement leads to absurd scenarios that cannot be true in real life and that an implementation of his thought experiment would not give the results that QM predicts. Unfortunately for Popper, it has taken until recently to perform experiments that test his claims. The results of the experiments do not refute QM as Popper predicted, but neither do they confirm what Popper claimed QM predicted. Kim and Shih implemented Popper's thought experiment in the lab. The results of the experiment are not clear and have instigated many interpretations of the results. The results show some correlation between entangled photons, but not in the way that Popper thought, nor in the way a simple application of QM might predict. A ghost-imaging experiment by Strekalov, et al. sheds light on the physics behind Popper's thought experiment, but does not try to directly test it. I will build the physics of Popper's thought experiment from the ground up and show how the results of both of these experiments agree with each other and the theory of QM, but disprove Popper.

Beauty Requires Thought.

Science.gov (United States)

Brielmann, Aenne A; Pelli, Denis G

2017-05-22

The experience of beauty is a pleasure, but common sense and philosophy suggest that feeling beauty differs from sensuous pleasures such as eating or sex. Immanuel Kant [1, 2] claimed that experiencing beauty requires thought but that sensuous pleasure can be enjoyed without thought and cannot be beautiful. These venerable hypotheses persist in models of aesthetic processing [3-7] but have never been tested. Here, participants continuously rated the pleasure felt from a nominally beautiful or non-beautiful stimulus and then judged whether they had experienced beauty. The stimuli, which engage various senses, included seeing images, tasting candy, and touching a teddy bear. The observer reported the feelings that the stimulus evoked. The time course of pleasure, across stimuli, is well-fit by a model with one free parameter: pleasure amplitude. Pleasure amplitude increases linearly with the feeling of beauty. To test Kant's claim of a need for thought, we reduce cognitive capacity by adding a "two-back" task to distract the observer's thoughts. The distraction greatly reduces the beauty and pleasure experienced from stimuli that otherwise produce strong pleasure and spares that of less-pleasant stimuli. We also find that strong pleasure is always beautiful, whether produced reliably by beautiful stimuli or just occasionally by sensuous stimuli. In sum, we confirm Kant's claim that only the pleasure associated with feeling beauty requires thought and disprove his claim that sensuous pleasures cannot be beautiful.

Aging and repeated thought suppression success.

Directory of Open Access Journals (Sweden)

Ann E Lambert

Full Text Available Intrusive thoughts and attempts to suppress them are common, but while suppression may be effective in the short-term, it can increase thought recurrence in the long-term. Because intentional suppression involves controlled processing, and many aspects of controlled processing decline with age, age differences in thought suppression outcomes may emerge, especially over repeated thought suppression attempts as cognitive resources are expended. Using multilevel modeling, we examined age differences in reactions to thought suppression attempts across four thought suppression sequences in 40 older and 42 younger adults. As expected, age differences were more prevalent during suppression than during free monitoring periods, with younger adults indicating longer, more frequent thought recurrences and greater suppression difficulty. Further, younger adults' thought suppression outcomes changed over time, while trajectories for older adults' were relatively stable. Results are discussed in terms of older adults' reduced thought recurrence, which was potentially afforded by age-related changes in reactive control and distractibility.

TBC-8, a Putative RAB-2 GAP, Regulates Dense Core Vesicle Maturation in Caenorhabditis elegans

Dense core vesicles (DCVs) are thought to be generated at the late Golgi apparatus as immature DCVs, which subsequently undergo a maturation process through clathrin-mediated membrane remodeling events. This maturation process is required for efficient processing of neuropeptides within DCVs and for removal of factors that would otherwise interfere with DCV release. Previously, we have shown that the GTPase, RAB-2, and its effector, RIC-19, are involved in DCV maturation in Caenorhabditis elegans motoneurons. In rab-2 mutants, specific cargo is lost from maturing DCVs and missorted into the endosomal/lysosomal degradation route. Cargo loss could be prevented by blocking endosomal delivery. This suggests that RAB-2 is involved in retention of DCV components during the sorting process at the Golgi-endosomal interface. To understand how RAB-2 activity is regulated at the Golgi, we screened for RAB-2–specific GTPase activating proteins (GAPs). We identified a potential RAB-2 GAP, TBC-8, which is exclusively expressed in neurons and which, when depleted, shows similar DCV maturation defects as rab-2 mutants. We could demonstrate that RAB-2 binds to its putative GAP, TBC-8. Interestingly, TBC-8 also binds to the RAB-2 effector, RIC-19. This interaction appears to be conserved as TBC-8 also interacted with the human ortholog of RIC-19, ICA69. Therefore, we propose that a dynamic ON/OFF cycling of RAB-2 at the Golgi induced by the GAP/effector complex is required for proper DCV maturation. PMID:22654674

The effects of thoughts of survival and thoughts of death on recall in the adaptive memory paradigm.

Science.gov (United States)

Klein, Stanley B

2014-01-01

In a recent paper Hart and Burns (2012) presented evidence that conditions that prime thoughts of one's mortality benefit recall. Drawing on the conceptual relation between thoughts of death and thoughts of survival, Hart and Burns interpret their findings as suggestive of the possibility that death-related thoughts function in manner similar to survival-related thoughts in enhancing recall. In the present study I draw on evolutionary arguments to question whether a conceptual relation between thoughts of death and thoughts of survival translates into a functional relation. I then present data showing that while death-related thoughts can promote high levels of recall, (a) the level achieved does not match that produced by survival processing and (b) survival and death cognition likely rely on different mechanisms to achieve their effects.

This study examined the value pluralism model in everyday value conflicts, and the effect of issue context on complexity of thought. According to the cognitive manager model we hypothesized that respondents would obtain a higher level of integrative complexity on personal issues that on professional and general issues. We also explored the relations of integrative complexity to value priorities, measured by the Schwartz Value Survey, and to emotional empathy. The value pluralism model was not supported by the data collected from 126 university students from social science, business and technology. The cognitive manager model was partially confirmed by data from females but not from males. Concerning value priorities, more complex respondents had higher regard for self-transcendence values, and less complex respondents for self-enhancement values Emotional empathy was also significantly related to complexity score.

This qualitative study explored perspectives of emerging adult African American women on the development of mature love relationships. Inductive analysis of focus group interviews, conducted with a purposive sample of 31 African American women, yielded themes related to relationship goals and characteristics, and interpersonal and societal challenges to finding the right partner and developing a mature love relationship. Core categories that emerged from analysis of the discussions were (1) age and relationship goal differences within the emerging adult group, (2) mature love relationship goals and characteristics, (3) interpersonal obstacles to finding the right partner, and (4) societal obstacles to finding the right partner. Two approaches-black womanist/feminist thought (Collins, 2000 ; Walker, 1983 ) and relationship maturity theory (Paul & White, 1990 )-were then combined to explain the influence of historic and contemporary interpersonal and societal factors on developmental and ethnic issues that challenge positive gender identity formation, hasten intimacy maturity, and hinder the development of mature love relationships among emerging adult African American women. For these women, premature responsibility, especially early caregiver burden, was related to the early development of intimacy capacity and the desire for a mature love relationship, to be protected, and to have someone to help carry the load. Interracial dating, negative stereotypic images of African American women, and even positive images of enduring black love relationships posed difficult challenges to positive identity formation and intimacy maturity. A primary challenge was to counteract negative stereotypic images, so that they could develop their own self-identities as women and as relationship partners.

In a global environment, education for healthcare professionals should include cultivating human resources who have the necessary skills to work in an international arena. This article will review the current status of English education for dental healthcare professionals in Japan. After conducting a literature search using the keywords: English education, Japan, and dental, only a few studies were found that investigated and proposed suggestions for dental professional English education. Even so, these were still in the early stages with outcomes yet to be fully evaluated. Even though English is thought indispensable for global professionals, and that increasing chances for communication skills is necessary, little attention has been addressed to English education for dental professionals or the implementation of such education in the Japanese undergraduate dental curricula. With the current reality of field expansion in dentistry, the need for not only improved English communication skills for Japanese dentists, but also the acquisition of essential expertise, psychomotor, teambuilding, critical thinking, and creative thinking skills in English as well as Japanese, is a definite probability. In order to reach this level of knowledge, further efforts and research would be necessary for the advancement and development of dental professional English education in Japan.

The aim of the study was to explore Slovenian midwives' views of their professional status. The influence of participants' educational background on their views was also examined, since higher education is related to professionalism. This was a quantitative descriptive survey, using postal data collection. The questionnaire comprised of six elements crucial for professionalism--three elements distinctive of 'old' professionalism (power, ethics, specific knowledge) and three characteristics of 'new' professionalism (reflective practice, inter-professional collaboration and partnership with users). A total of 300 midwives who were registered in a national register of nurses and midwives at the time of the study. The response rate was 50.7% (152 returned the questionnaire). Participants that were on a probationary period were excluded, leaving 128 questionnaires for analysis (43%). Some 40.9% participants had secondary midwifery education, 56.7% had higher midwifery education and only few (2.4%) finished postgraduate education. The majority of participants did not consider midwifery to be a specific profession. Midwives with secondary education were more likely to consider practical skills to be important than theoretical midwifery knowledge. In general midwives did not feel enabled to practice autonomously; and this caused them to face ethical dilemmas when aiming to fulfil women's wishes. All participants with midwifery secondary school education thought that obstetrics jeopardises midwifery scope of practice, but only half of the BSc participants thought this. One-fifth of all participants estimated that midwifery is also threatened by nursing. The respondents reported feeling a lack of control over their professional activity and policy making; however the majority of midwives claimed that they were willing to take on more responsibility for independent practice. Slovenian midwifery cannot be considered to be a profession yet. It faces several hindrances, due to

Cortical maturation, especially gyral formation, follows a temporospatial schedule and is a good marker of fetal maturation. Although ultrasonography is still the imaging method of choice to evaluate fetal anatomy, MRI has an increasingly important role in the detection of brain abnormalities, especially of cortical development. Knowledge of MRI techniques in utero with the advantages and disadvantages of some sequences is necessary, in order to try to optimize the different magnetic resonance sequences to be able to make an early diagnosis. The different steps of cortical maturation known from histology represent the background necessary for the understanding of maturation in order to be then able to evaluate brain maturation through neuroimaging. Illustrations of the normal cortical maturation are given for each step accessible to MRI for both the cerebral hemispheres and the posterior fossa. (orig.)

To explore how centenarians think about and plan for the end of life (EOL) and to what extent their primary contacts (proxy informants) are aware of these thoughts. Population-based study with semistructured in-person interviews. Defined geographical region approximately 60 km around Heidelberg, Germany. Subsample drawn from the larger study of centenarians (N = 78) with data on centenarians' EOL thoughts from the centenarian and the proxy informant. Centenarians reported on their thoughts about the EOL, perception of the EOL as threatening, longing for death, engagement in any EOL planning, and type of EOL plan (will, living will, healthcare surrogate) in place. Proxy respondents answered the same set of questions based on what they thought the centenarians' perspective was. In nearly half of cases, proxies misjudged whether the centenarian thought about EOL. Although only few centenarians perceived the EOL as threatening, and approximately one-quarter reported longing for death, proxies overestimated centenarians' reports on the former and underestimated the latter. Proxies reported more centenarian EOL planning than centenarians themselves. Even though enrolled proxies were mostly persons very close to the centenarian, many of them did not seem to be well informed about the centenarians' thoughts and plans regarding the EOL, suggesting a lack of communication between centenarians and social network members in this respect. Healthcare professionals should be aware that, even for very old adults approaching the end of their lives, discussions about EOL and EOL planning may need to be actively encouraged and supported. © 2018, Copyright the Authors Journal compilation © 2018, The American Geriatrics Society.

Manic thinking: independent effects of thought speed and thought content on mood.

Science.gov (United States)

Pronin, Emily; Wegner, Daniel M

2006-09-01

This experiment found that the speed of thought affects mood. Thought speed was manipulated via participants' paced reading of statements designed to induce either an elated or a depressed mood. Participants not only experienced more positive mood in response to elation than in response to depression statements, but also experienced an independent increase in positive mood when they had been thinking fast rather than slow--for both elation and depression statements. This effect of thought speed extended beyond mood to other experiences often associated with mania (i.e., feelings of power, feelings of creativity, a heightened sense of energy, and inflated self-esteem or grandiosity).

We examined two hypotheses regarding the potential association of pornography use with body image-related and eating disorder-related psychopathology among sexual minority males (i.e. non-heterosexual males). Our primary hypothesis was that pornography use would be associated with males' body dissatisfaction, eating disorder symptoms, thoughts about using anabolic steroids and quality of life impairment; our secondary hypothesis was that the type of pornography, namely, professional versus amateur pornography, which contains idealised and non-idealised (i.e. regular) bodies, respectively, would moderate these associations. A sample of 2733 sexual minority males living in Australia and New Zealand completed an online survey that contained measures of pornography use, body dissatisfaction, eating disorder symptoms, thoughts about using anabolic steroids and quality of life. Almost all (98.2%) participants reported pornography use with a median use of 5.33 hours per month. Multivariate analyses revealed that increased pornography use was associated with greater dissatisfaction with muscularity, body fat and height; greater eating disorder symptoms; more frequent thoughts about using anabolic steroids; and lower quality of life. Effect sizes for these associations were uniformly small. Neither relationship status nor genital dissatisfaction was associated with pornography use. The association between pornography use and thoughts about using anabolic steroids was stronger for viewers of professional pornography than viewers of amateur pornography. The findings suggest that the use of pornography is weakly associated with body dissatisfaction and related variables and that the type of pornography (amateur vs professional) viewed may be a moderating factor in some cases. Within the limits of a cross-sectional study design, these findings may have implications for clinicians who treat individuals with eating disorders, body dysmorphic disorder, anabolic-androgenic steroid

Psychopathology and Thought Suppression: A Quantitative Review

Science.gov (United States)

Magee, Joshua C.; Harden, K. Paige; Teachman, Bethany A.

2012-01-01

Recent theories of psychopathology have suggested that thought suppression intensifies the persistence of intrusive thoughts, and proposed that difficulty with thought suppression may differ between groups with and without psychopathology. The current meta-analytic review evaluates empirical evidence for difficulty with thought suppression as a function of the presence and specific type of psychopathology. Based on theoretical proposals from the psychopathology literature, diagnosed and analogue samples were expected to show greater recurrence of intrusive thoughts during thought suppression attempts than non-clinical samples. However, results showed no overall differences in the recurrence of thoughts due to thought suppression between groups with and without psychopathology. There was, nevertheless, variation in the recurrence of thoughts across different forms of psychopathology, including relatively less recurrence during thought suppression for samples with symptoms of Obsessive-Compulsive Disorder, compared to non-clinical samples. However, these differences were typically small and provided only mixed support for existing theories. Implications for cognitive theories of intrusive thoughts are discussed, including proposed mechanisms underlying thought suppression. PMID:22388007

OBJECTIVE. Medical professionalism has been widely discussed in western scholarly literature. However, since Hong Kong has a mixed Chinese-western culture, it remains uncertain whether Hong Kong health care professionals, medical students, and patients see medical professionalism in exactly the same way as westerners. The objective of the present study was to explore perceptions of medical professionalism in Hong Kong. DESIGN. Individual semi-structured interviews. SETTING. Medical faculty preceptors, residents, interns, nurses, and students from the Li Ka Shing Faculty of Medicine of the University of Hong Kong. Subjects were recruited at an out-patient clinic of Queen Mary Hospital. PARTICIPANTS. We interviewed 39 subjects, including six medical faculty preceptors, six hospital residents, four medical interns, eight nurses, eight out-patients, and seven medical students. The interviews were transcribed and coded. Grounded theory was employed for framing and analysing the interviews. RESULTS. A total of 30 primary themes were identified and grouped under three secondary themes, ie 'Expectations of a professional doctor', 'Work values', and 'Patient care'. In general, the primary themes were consistent with recognised professional attributes in western bioethics, such as knowledge and skills, holistic care, and communication skills. A closer analysis suggested that traditional Chinese thought also played an important role in shaping the medical professionalism of Hong Kong. Challenges to be faced by Hong Kong doctors due to recent social changes were also identified. CONCLUSIONS. Medical professionalism in Hong Kong is shaped by both western medical ethics and traditional Chinese thought. The values treasured by Hong Kong health care professionals as well as technological advance, and the city's proximity to Mainland China makes Hong Kong health care unique. It is important to maintain the present work attitudes and at the same time adapt to new social changes.

Relationships between thought-action fusion, thought suppression and obsessive-compulsive symptoms: a structural equation modeling approach.

Research has shown that there are strong similarities in content between the obsessions and compulsions that characterize obsessive-compulsive disorder and nonclinical obsessions and compulsions. However, clinical and nonclinical obsessions and compulsions do differ with respect to characteristics like frequency, intensity, discomfort and elicited resistance. Two separate concepts have been invoked to explain how normal obsessions and compulsions may develop into clinical phenomena. First, it is suggested that thought-action fusion (TAF) contributes to obsessive-compulsive symptoms. Second, thought suppression may intensify obsessive-compulsive symptoms due to its paradoxical effect on intrusive thoughts. Although both phenomena have been found to contribute to obsessive-compulsive symptoms, possible interactions between these two have never been investigated. The current study explored how TAF and thought suppression interact in the development of obsessive-compulsive symptoms. Undergraduate psychology students (N = 173) completed questionnaires pertaining to TAF, thought suppression and obsessive-compulsive symptoms. Covariances between the scores on these questionnaires were analyzed by means of structural equation modeling. Results suggest that TAF triggers thought suppression, while thought suppression, in turn, promotes obsessive-compulsive symptoms.

The idea of civil control in the European political and legal thought

2015-12-01

Full Text Available The article discusses the problem of defining the role and functions of civil control from the political and legal thought perspective and in the context of the possible ways of civil society and state authorities interaction. The demand for external evaluation as a prerequisite for the development of political system and the demand for establishing an effective feedback mechanism within it together with the lack of a unified approach to the interpretation of civil control in the political science and legal doctrines determined the relevance of the study of the established traditions in the interpretation of civil control in social sciences and humanities. Whereas social and power relations always develop within a specific legislative framework, whose maturity and consistency largely determine the state of civil society, it is not possible to evaluate control functions of the public sector otherwise than through the study of the legal framework of the state. Thus, the article describes the evolution of the views on possible formats of social and power relations in the context of transformations of the European social thought and political and legal approaches to the perception of power institutions, building a dialogue between social and political organizations, defining the forms of civic participation in political decision-making and interpretation of civil control.

Although an inflated sense of responsibility, thought-action fusion, and thought suppression are influential factors in cognitive models of obsessive-compulsive disorder (OCD), their impact on OCD has generally been demonstrated in samples from Western countries. The aim of the present study is to evaluate these cognitive factors in Turkish patients with OCD, other anxiety disorders, and community controls. Group comparisons showed that responsibility based on self-dangerousness and thought suppression significantly distinguished OCD patients from patients with other anxiety disorders and controls. Moreover, correlation and discriminant function analyses indicated that thought-action fusion in morality and likelihood was also associated with OCD symptoms. The present findings provide support for the international validity and specificity of cognitive factors and model for OCD.

Full Text Available Background: The aim of this study was to explore dental maturation as a diagnostic test for skeletal maturation. Materials and Methods: Six hundred and fifty-seven growing individuals were classified according to their cervical vertebral maturity and dental maturity, both determined in lateral cephalograms and panoramic radiographs, respectively. The correlation between cervical and dental stages was established for each gender. A receiver operating characteristic curve analysis was made, and sensitivity and specificity values were established. Results: Correlation was found between cervical and dental maturation for females (r = 0.73; P<0.001 and males (r = 0.60; P<0.001. Sensitivity for dental Stage F, as an indicator of a postmaturation peak stage, was 87.21% for females and 97.1% for males, whereas specificity for the same stage was 82.92% and 72.3% for females and males, respectively. Conclusions: Dental maturation evaluation could contribute determining whether a patient is in a pre- or post-growth spurt stage.

Age-adjusted stroke mortality rates in Israel are higher among Arabs compared with Jews; therefore, knowledge of stroke signs and prevention strategies is especially important in the Arab population. Data on stroke knowledge among Arabs in Israel are lacking. We aimed to examine knowledge, perceptions and thoughts of stroke among Arab-Muslim Israelis. A complementary mixed method design was used. Ninety-nine Arab Muslims living in Israel, older than 40 years, with no history of stroke, were personally interviewed. Knowledge of stroke was assessed using quantitative analysis by a semi-structured interview. Information on perceptions and thoughts evoked by stroke was analyzed using qualitative analysis by the constant comparative method. Rates of reported knowledge-related variables were presented. Mean (SD) age of participants was 50.1 (8.0) years, 52.5% were women. Most of the participants (84.8%) knew the causes of stroke but only 29.3% mentioned sudden weakness or paralysis in one side of the body as a warning sign and other warning signs were even less known. The main known risk factor was hypertension (43.3%). Although knowledge of stroke prevention was poor, 89% were interested in learning about stroke and its prevention. The qualitative findings showed that stroke evokes negative thoughts of mental and physical burden and is associated with death, disability, dependence and depression. Levels of stroke knowledge among Arab-Muslim Israelis are low to moderate. Healthcare professionals should assist high risk populations in controlling and treating risk factors in order to reduce mortality and disability following a stroke.

Full Text Available Introduction: Radiographs are effective tools in assessing the stages of bone maturation in dentistry. The cervical vertebral maturation method is a proven effective tool in assessing the adolescent growth spurt than hand-wrist radiographs in an individual. Assessment of dental calcification stages are a reliable method for determining dental maturity. Panoramic imaging can be used as the primary imaging modality for assessing maturity if a correlation can be found out between tooth calcification stages and cervical vertebral maturation stages. This study was conducted to determine the correlation between dental maturity stage and cervical vertebral maturity stage and to estimate predictor variables for cervical vertebral maturation stages (CVMS stratified by gender in a tertiary hospital setting. Materials and Methods: A descriptive study was conducted among patients accessing orthodontic care in radiology outpatient clinic, Oral Medicine and Radiology department, Government Dental College Thiruvananthapuram for a period of 15 months. Participants were selected between the ages of 8 and 16 years. Panoramic radiographs and lateral cephalograms were used to determine dental maturity stages using Demirjian method and CVMS using Bacetti and Franchi method, respectively. Results: One hundred patients (males = 46, females = 54 were included in the study; the spearman rank order correlation revealed significant relationship. The correlation ranged from 0.61 to 0.74 for females and 0.48 to 0.51 for males. Second premolar showed highest correlation and canine the lowest for both females and males. Stage G of mandibular second premolar signifies the pubertal growth period in this study population. By ordinal regression model, G stage of second premolar was found to be a significant predictor in males and stage H followed by G and F in females for the age group of 12–14 years. Conclusion: Dental maturation stages were significantly correlated with CVMS

Some different thoughts on the problem of replacements for the aging professionals

The aging of the professional in nuclear criticality safety is no longer a matter for a humorous line or a friendly jibe while attending to the business of the discipline. There is one aspect of this problem that is especially serious and should receive some helpful attention; namely the need to maintain the strength and vigor of nuclear engineering in leading colleges and universities. The struggle for resources in a static funding climate for the overall university while in direct competition with growing electrical engineering and computer engineering programs is in many cases a desperate one for the small and usually shrinking nuclear engineering programs. Formula funding based on student credit hours taught is very intolerant of the consequences of years of bad press

Critical role for invariant chain in CD1d-mediated selection and maturation of Vα14-invariant NKT cells.

The development and maturation of Vα14 invariant (i)NKT cells in mice requires CD1d-mediated lipid antigen presentation in the thymus and the periphery. Cortical thymocytes mediate positive selection, while professional APCs are involved in thymic negative selection and in terminal maturation of iNKT cells in the periphery. CD1d requires entry in the endosomal pathway to allow antigen acquisition for assembly as lipid/CD1d complexes for display to iNKT cells. This process involves tyrosine-based sorting motifs in the CD1d cytoplasmic tail and invariant chain (Ii) that CD1d associates with in the endoplasmic reticulum. The function of Ii in iNKT cell thymic development and peripheral maturation had not been fully understood. Using mice deficient in Ii and the Ii-processing enzyme cathepsin S (catS), we addressed this question. Ii(-/-) mice but not catS(-/-) mice developed significantly fewer iNKT cells in thymus, that were less mature as measured by CD44 and NK1.1 expression. Ii(-/-) mice but not catS(-/-) mice developed fewer Vβ7(+) cells in their iNKT TCR repertoire than WT counterparts, indicative of a change in endogenous glycolipid antigen/CD1d-mediated iNKT cell selection. Finally, using a Mycobacterium tuberculosis infection model in macrophages, we show that iNKT developed in Ii(-/-) but not catS(-/-) mice have defective effector function. Our data support a role for professional APCs expressing Ii, but no role for catS in the thymic development and peripheral terminal maturation of iNKT cells. Copyright © 2011 Elsevier B.V.

We carried out a study with 91 nurses, trying to find out about the feelings of these professionals regarding their satisfaction at work. We used the Work Satisfaction Assessment Questionnaire (WSAQ), drawn up and validated by Siqueira (1978) and adapted with the analysis of seven factors: General Satisfaction; Physical and Psychological Stress; "Status" of the Job; Location of the Company; Compensating Benefits; Recognition and Personal Development. Data showed nurses satisfied with their work, in its intrinsic aspects (Accomplishment, Recognition and Autonomy). The psychiatric nurses were the most mature, most experienced, showing a higher satisfaction level, whereas the pediatric nurses were the youngest, most inexperienced and presenting the highest level of dissatisfaction at work.

Full Text Available Introduction. The article analyzes the phenomenon of emotional maturity from the position of various psychological approaches (psychoanalytic, existential, humanistic, cognitive, cultural-historical. It is emphasized that the problem of studying emotional maturity, its structure, mechanisms, conditions of formation, especially in the context of growing young people and preparing for the implementation of specific professional activities, remains the subject of scientific discussions and is not fully understood by domestic and foreign psychologists.Materials and Methods. The results of our own research in the period 2015-2017 are described. on the sample of students of three faculties of the pedagogical university (Mininsky University (the volume of 157 people of the indicators of emotional maturity in accordance with the presented author's model, which includes the following components: emotional value orientation, cognitive reactions and emotional cognition, affective reactions, emotional self-regulation of behavior.Results. The system of mechanisms of fastening and manifestation of emotions at different levels of the personality structure characterizing the opposite variants of emotional development of students is described: crisis and mature. A significant percentage of the young people surveyed (44, 6 with a crisis type of emotional development was revealed. These subjects have significantly higher rates of personal anxiety and accompanying experiences of fear, shame and guilt, a less developed ability to emotionally cognize and control their emotions, dominate strategies to avoid difficulties and problems, as well as aggressive behavior towards others in stressful situations.Discussion and Conclusions. The obtained results testify to the need for special psychological work with students-future teachers in the framework of training.

On the origins of endogenous thoughts.

Science.gov (United States)

Tillas, Alexandros

2017-05-01

Endogenous thoughts are thoughts that we activate in a top-down manner or in the absence of the appropriate stimuli. We use endogenous thoughts to plan or recall past events. In this sense, endogenous thinking is one of the hallmarks of our cognitive lives. In this paper, I investigate how it is that we come to possess endogenous control over our thoughts. Starting from the close relation between language and thinking, I look into speech production-a process motorically controlled by the inferior frontal gyrus (IFG). Interestingly, IFG is also closely related to silent talking, as well as volition. The connection between IFG and volition is important given that endogenous thoughts are or at least greatly resemble voluntary actions. Against this background, I argue that IFG is key to understanding the origins of conscious endogenous thoughts. Furthermore, I look into goal-directed thinking and show that IFG plays a key role also in unconscious endogenous thinking.

Full Text Available In cognitive science, the discussion about the relations between language and thought is very heterogeneous. It involves developments on linguistics, philosophy, psychology, etc. Carruthers and Boucher (1998 identify different criteria that would organize the diversity of positions about language and thought assumed in linguistics, philosophy and psychology. One of them is the constitution thesis (CT, which establishes that language is constitutively involved in thought. In this paper I would like to show some problems of CT in order to understand the relation between language and thought in cognitive science.

Caffeine withdrawal was included in the research appendix of the DSM-IV to encourage additional research to assist with determining its status for the next version of the manual. Caffeine dependence was not included because of a lack of empirical research at the time of publication. This study assessed the beliefs of addiction professionals about the clinical importance of caffeine withdrawal and dependence. A 6-item survey was developed and delivered electronically to the members of six professional organizations that focus on addiction. Open-ended comments were also solicited. Five hundred members responded. The majority (95%) thought that cessation of caffeine could produce a withdrawal syndrome, and that caffeine withdrawal can have clinical importance (73%); however, only half (48%) thought that caffeine withdrawal should be included in the Diagnostic and Statistical Manual of Mental Disorders (DSM). A majority (58%) believed that some people develop caffeine dependence; however, only 44% indicated that it should be in the DSM. Comments suggested that trepidation about inclusion of caffeine diagnoses was due to the concerns about the field of psychiatry being criticized for including common disorders with a relatively low clinical severity. Others, however, expressed an urgent need to take caffeine-related problems more seriously. The majority of addiction professionals believe that caffeine withdrawal and dependence disorders exist and are clinically important; however, these professionals are divided in whether caffeine withdrawal and dependence should be included in DSM. Wider dissemination of the extant literature on caffeine withdrawal and additional research on caffeine dependence will be needed to provide additional guidance to policymakers and healthcare workers.

Roush, Jared F; Brown, Sarah L; Jahn, Danielle R; Mitchell, Sean M; Taylor, Nathanael J; Quinnett, Paul; Ries, Richard

2018-01-01

Approximately 20% of suicide decedents have had contact with a mental health professional within 1 month prior to their death, and the majority of mental health professionals have treated suicidal individuals. Despite limited evidence-based training, mental health professionals make important clinical decisions related to suicide risk assessment and management. The current study aimed to determine the frequency of suicide risk assessment and management practices and the association between fear of suicide-related outcomes or comfort working with suicidal individuals and adequacy of suicide risk management decisions among mental health professionals. Mental health professionals completed self-report assessments of fear, comfort, and suicide risk assessment and management practices. Approximately one third of mental health professionals did not ask every patient about current or previous suicidal thoughts or behaviors. Further, comfort, but not fear, was positively associated with greater odds of conducting evidence-based suicide risk assessments at first appointments and adequacy of suicide risk management practices with patients reporting suicide ideation and a recent suicide attempt. The study utilized a cross-sectional design and self-report questionnaires. Although the majority of mental health professionals report using evidenced-based practices, there appears to be variability in utilization of evidence-based practices.

The influence of Masters education on the professional lives of British and German nurses and the further professionalization of nursing.

Watkins, Dianne

2011-12-01

 This article reports on findings from a qualitative study which explored the influence of a Masters in Nursing on the professional lives of British and German nurses and its role in further professionalizing nursing. A collaborative Masters programme was delivered in the United Kingdom and Germany. This provided an opportunity to study the influence of the programme on the professionalization of nursing in different country contexts. Continuing education is thought to contribute to furthering professionalization. Evidence to support this in the field of nursing is limited. An interpretive research design was used and data were collected via semi-structured interviews with ten German nurses and nine British nurses. Data were collected in the United Kingdom and Germany from August 2006 to February 2007. Interviews were recorded and transcribed, and data were analysed using a template approach with further immersion and crystalization of the data. Nurses' personal and professional confidence improved; research-based evidence was used to underpin changes made to practice; new roles and careers emerged; multi-professional working was enhanced; and nurses rediscovered nursing and championed the profession. A diagram is presented based on the findings. Masters education is at the centre as the catalyst with four interconnecting circles, which depict elements that contribute to professionalization. The diagram highlights overlap and interplay between nurses' increased personal confidence, improved cognitive functioning, evidence-based practice development and enhanced professionalism. Findings support the theory that this Masters in Nursing programme enhanced practice and further professionalization of nursing in both countries. © 2011 Blackwell Publishing Ltd.

Li, Jiansheng; Zhu, Yawen; Yang, Yang

2014-01-01

According to unconscious thought theory (UTT), unconscious thought is more adept at complex decision-making than is conscious thought. Related research has mainly focused on the complexity of decision-making tasks as determined by the amount of information provided. However, the complexity of the rules generating this information also influences decision making. Therefore, we examined whether unconscious thought facilitates the detection of rules during a complex decision-making task. Participants were presented with two types of letter strings. One type matched a grammatical rule, while the other did not. Participants were then divided into three groups according to whether they made decisions using conscious thought, unconscious thought, or immediate decision. The results demonstrated that the unconscious thought group was more accurate in identifying letter strings that conformed to the grammatical rule than were the conscious thought and immediate decision groups. Moreover, performance of the conscious thought and immediate decision groups was similar. We conclude that unconscious thought facilitates the detection of complex rules, which is consistent with UTT.

How does thought-action fusion relate to responsibility attitudes and thought suppression to aggravate the obsessive-compulsive symptoms?

Science.gov (United States)

Altın, Müjgan; Gençöz, Tülin

2011-01-01

Comprehensive cognitive theories of obsessive compulsive disorder (OCD) propose that clinical obsessions and compulsions arise from specific sorts of dysfunctional beliefs and appraisals, such as inflated sense of responsibility, thought-action fusion (TAF), and thought suppression. The present study aimed to examine the mediator roles of responsibility and thought suppression between TAF and obsessive-compulsive symptoms. Specifically, it aimed to explore the relative effects of TAF factors (i.e. morality and likelihood) on inflated sense of responsibility and on thought suppression to increase the obsessive qualities of intrusions. Two hundred and eighty-three Turkish undergraduate students completed a battery of measures on responsibility, thought suppression, TAF, OC symptoms, and depression. A series of hierarchical regression analyses, where depressive symptoms were controlled for, indicated that TAF-morality and TAF-likelihood follow different paths toward OC symptoms. Although TAF-morality associated with inflated sense of responsibility, TAF-likelihood associated with thought suppression efforts, and in turn these factors increased OC symptoms. These findings provide support for the critical role of sense of responsibility and thought suppression between the relationship of TAF and OC symptoms. Findings were discussed in line with the literature.

Fostering values: four stages towards developing professional ethics for future accountants

Full Text Available The many accounting scandals occurred in the last three decades have change the perspective of accountant globally. As such, the higher institutions have to play their role in nurturing professional ethics in order to change the misconception towards the profession. Our observation of the literature indicates that incorporating professional ethics in higher institutions is a way forward towards developing future accountants with values. Henceforth, we conducted a generic inquiry study to explore how higher institutions could inculcate accounting graduates with professional ethics. Our findings show a conceptual framework which depicted four stages towards incorporating professional ethics at tertiary level education there are: 1 value development, 2 ethics maturation, 3 professionalism development and 4 ownership through effective implementation and enforcement. Consequently, the findings contribute to expanding the current knowledge in our conceptualisation of the professional ethics concept. In addition, the findings support the development of ethics education for accounting graduates in higher institutions in Malaysia. We consider that this study provides evidence to educators and policy makers that teaching methods and pedagogical policies should ensure professional ethics education in business schools in Malaysia is treated as a pervasive element of curricula rather than an optional choice.

Professional formation through personal involvement and value integration.

Haugland, Britt Øvrebø; Lassen, Rasmus M; Giske, Tove

2018-03-01

Formation is an important part of nursing education, and it is the responsibility of nurse educators to facilitate learning situations that provide students with opportunities for personal discovery. Studies have shown that awareness of one's own vulnerability can be a source of professional maturation and courageous action. The study setting is a Christian university that emphasises its value base through the perspective of diakonia in the nursing programme. Diakonia is understood as the provision of caring. Two hundred and forty-five pages of reflective journals from 124 third-year students were analysed with qualitative content analysis. The main theme of the study was Professional formation through personal involvement and value integration. Four categories emerged: 1) Diakonia as a guide to professional compassion; 2) Consciousness of one's own values; 3) The urge to act courageously; and 4) Choosing to spend the time available. The article discusses how students can integrate values in their professional lives by using all senses when learning in real-life situations and by using systematic reflection alone and together with others. Professional formation is an ongoing process, and we have found that mandatory participation, reiteration and progression are important conditions for such formation to occur.

MatureBayes: a probabilistic algorithm for identifying the mature miRNA within novel precursors.

Directory of Open Access Journals (Sweden)

Katerina Gkirtzou

Full Text Available BACKGROUND: MicroRNAs (miRNAs are small, single stranded RNAs with a key role in post-transcriptional regulation of thousands of genes across numerous species. While several computational methods are currently available for identifying miRNA genes, accurate prediction of the mature miRNA remains a challenge. Existing approaches fall short in predicting the location of mature miRNAs but also in finding the functional strand(s of miRNA precursors. METHODOLOGY/PRINCIPAL FINDINGS: Here, we present a computational tool that incorporates a Naive Bayes classifier to identify mature miRNA candidates based on sequence and secondary structure information of their miRNA precursors. We take into account both positive (true mature miRNAs and negative (same-size non-mature miRNA sequences examples to optimize sensitivity as well as specificity. Our method can accurately predict the start position of experimentally verified mature miRNAs for both human and mouse, achieving a significantly larger (often double performance accuracy compared with two existing methods. Moreover, the method exhibits a very high generalization performance on miRNAs from two other organisms. More importantly, our method provides direct evidence about the features of miRNA precursors which may determine the location of the mature miRNA. We find that the triplet of positions 7, 8 and 9 from the mature miRNA end towards the closest hairpin have the largest discriminatory power, are relatively conserved in terms of sequence composition (mostly contain a Uracil and are located within or in very close proximity to the hairpin loop, suggesting the existence of a possible recognition site for Dicer and associated proteins. CONCLUSIONS: This work describes a novel algorithm for identifying the start position of mature miRNA(s produced by miRNA precursors. Our tool has significantly better (often double performance than two existing approaches and provides new insights about the potential use

Leveraging People-Related Maturity Issues for Achieving Higher Maturity and Capability Levels

Science.gov (United States)

Buglione, Luigi

During the past 20 years Maturity Models (MM) become a buzzword in the ICT world. Since the initial Crosby's idea in 1979, plenty of models have been created in the Software & Systems Engineering domains, addressing various perspectives. By analyzing the content of the Process Reference Models (PRM) in many of them, it can be noticed that people-related issues have little weight in the appraisals of the capabilities of organizations while in practice they are considered as significant contributors in traditional process and organizational performance appraisals, as stressed instead in well-known Performance Management models such as MBQA, EFQM and BSC. This paper proposes some ways for leveraging people-related maturity issues merging HR practices from several types of maturity models into the organizational Business Process Model (BPM) in order to achieve higher organizational maturity and capability levels.

The consequence of the second view is that pragmatism and relativism become the dominant features. This article discusses…

A Penny for Your Thoughts: Dimensions of Thought Content and Relationships with Individual Differences in Emotional Well-Being

Directory of Open Access Journals (Sweden)

Jessica R Andrews-Hanna

2013-11-01

Full Text Available A core aspect of human cognition involves overcoming the constraints of the present environment by mentally simulating another time, place, or perspective. Although these self-generated processes confer many benefits, they can come at an important cost, and this cost is greater for some individuals than for others. Here we explore the possibility that the costs and benefits of self-generated thought depend, in part, upon its phenomenological content. To test these hypotheses, we first developed a novel thought sampling paradigm and explored normative ratings of multiple thought content variables (i.e. valence, specificity, self-relevance, etc. across a large sample of young adults. Next, we examined multi-level relationships among these content variables, and used a hierarchical clustering approach to partition self-generated thought into multiple dimensions. Finally, we investigated whether these content dimensions predicted individual differences in the costs and benefits of the experience, assessed with questionnaires measuring emotional health and wellbeing. Individuals who characterized their thoughts as more negative and more personally-significant exhibited scored higher on constructs associated with Depression and Trait Negative Affect, whereas those who characterized their thoughts as less specific scored higher on constructs linked to Rumination. In contrast, individuals who characterized their thoughts as more positive, less personally-significant, and more specific scored higher on constructs linked to improved wellbeing (Mindfulness. Collectively, these findings suggest that the content of people’s inner thoughts can 1 be productively examined, 2 be distilled into several major dimensions, and 3 account for a large portion of variability in their functional outcomes.

Maturity models are widespread in IS research and in particular, IT practitioner communities. However, theoretically sound, methodologically rigorous and empirically validated maturity models are quite rare. This literature review paper focuses on the challenges faced during the development...... literature reveals that researchers have primarily focused on developing new maturity models pertaining to domain-specific problems and/or new enterprise technologies. We find rampant re-use of the design structure of widely adopted models such as Nolan’s Stage of Growth Model, Crosby’s Grid, and Capability...... Maturity Model (CMM). Only recently have there been some research efforts to standardize maturity model development. We also identify three dominant views of maturity models and provide guidelines for various approaches of constructing maturity models with a standard vocabulary. We finally propose using...

Modeling non-maturing liabilities

2011-01-01

Non‐maturing liabilities, such as savings accounts, lack both predetermined maturity and reset dates due to the fact that the depositor is free to withdraw funds at any time and that the depository institution is free to change the rate. These attributes complicate the risk management of such products and no standardized solution exists. The problem is important however since non‐maturing liabilities typically make up a considerable part of the funding of a bank. In this report different mode...

Individual differences in the growth and maturation have been shown to impact player performance and development in youth soccer. This study investigated Premier League academy players' experiences of participating in a tournament bio-banded for biological maturation. Players (N = 66) from four professional soccer clubs aged 11 and 14 years and between 85-90% of adult stature participated in a tournament. Players competed in three 11 vs 11 games on a full size pitch with 25-min halves. Sixteen players participated in four 15-min focus groups and were asked to describe their experiences of participating in the bio-banded tournament in comparison to age group competition. All players described their experience as positive and recommended the Premier League integrate bio-banding into the existing games programme. In comparison to age-group competitions, early maturing players described the bio-banded games more physically challenging, and found that they had to adapt their style of play placing a greater emphasis on technique and tactics. Late maturing players considered the games to be less physically challenging, yet appreciated the having more opportunity to use, develop and demonstrate their technical, physical, and psychological competencies. Bio-banding strategies appear to contribute positively towards the holistic development of young soccer players.

The Connection between the Thought of Progress and Philosophical Thinking in the West Case Study: Descartes’ Thought System

Seyed Mustafa Shahraeeni

2015-03-01

Full Text Available Thought of progress has been considered as one of the presuppositions of the West modernity. Having accepted this idea, we should regard it as one of the bases and foundations of early modern philosophy, and consider Descartes, known as the father of modern philosophy, as having a major role in its formation. There is a strong relationship between the West philosophical thought and the change of the idea of progress to one of the undisputed facts of the west civilization, and this issue can be seen clearly in Descartes thought system better than anywhere else. The present paper intends to show the leading position of Descartes’ thought system in the institutionalization of the concept of progress in the West philosophical system in three main parts: 1. Authority fighting and its relation with Cartesian’s Doubt, 2. The genuineness of the worldly life in Descartes’ thought system, and 3. Establishing the foundation of modern science. This article is based on the modern forerunners’ change of opinion about the philosophy mission in the world. It  makes attempt to demonstrate in order to achieve the thought of progress, some prerequisites are necessary; and these prerequisite, though not exclusively, in their best and most complete form are generally achieved in the West philosophical thought and are particularly accomplished in Descartes’ philosophy.

Full Text Available Children born later in the year of competition have lower chances of promotion due to their low degree of physical, mental and emotional maturity. This phenomenon is known as Relative Age Effect or RAE. The objective of this study is to determine if the date of birth (month of birth is a factor in the configuration of the professional teams of Spanish football. As for the methodology, we determined the months of birth of the players of the first and second division of Spanish football. A total of 42 professional teams were analyzed. The data were arranged in semesters and quarters. The results show that there is a strong tendency for the selection of professional players born in the first quarters of the year compared to those born in the later ones. In conclusion, in Spain there is a predominance of professional football players depending on the month of birth

Non-erotic thoughts and sexual functioning.

This study sought to replicate and extend investigations of current models of sexual dysfunction (Barlow, 2002; Janssen, Everaerd, Spiering, & Janssen, 2000) which implicate factors such as spectatoring, failure to use ameliorative strategies, and information processing biases in the development and persistence of sexual difficulties. A sample of 165 (n = 71 men) undergraduates completed measures of sexual dysfunction and relationship satisfaction, and reported on the content and frequency of non-erotic thoughts during sex with a partner (i.e., spectatoring), the emotional impact of non-erotic thoughts, and the strategies used to manage them. They also reported on their main sexual functioning difficulties and the strategies they used to manage those difficulties. Finally, participants were presented with a series of hypothetical sexual scenarios and were asked to report their immediate interpretation of events in the scenario. The content of non-erotic thoughts was similar to previous work (Purdon & Holdaway, 2006), although gender differences in thought content were less pronounced. As in previous research, greater frequency of, and anxiety evoked by, non-erotic thoughts was associated with poorer sexual functioning, but we found that this was over and above relationship satisfaction. Participants both high and low in sexual functioning reported using a variety of strategies to manage their non-erotic thoughts, thought suppression being the least effective, and also used a variety of strategies to manage sexual difficulties. Poorer sexual functioning was associated with more negative interpretations of ambiguous sexual scenarios, but this was mediated by relationship satisfaction. However, positive interpretations were predicted by sexual functioning. Results were discussed in terms of their theoretical and clinical implications.

Full Text Available One of the central problems of current economic development and industrial competitiveness, social and scientific, is the complexity of large and intensive software systems, and processes for their development and implementation. This complexity is defined by the amount and heterogeneity of the interaction of the hardware with the software components, their inter-relationships, of incorporation of the technical and organizational environments, and the interfaces to humans. The domain of these systems requires actions and scientific thoughts, hierarchical and systematic; also, the success of the products, services and organizations, is increasingly determined by the availability of suitable software products. Therefore, highly qualified professionals, able to understand and master the systems, involved in the entire life cycle of software engineering, and adopt different roles during the development. This is the reason that guide the thinking of this Manifesto , which aims is to achieve the Professionalization of Software Development.

2017-01-01

Full Text Available Background: The aim of the present study was to compare the cervical vertebra maturation stages method and dental maturity using tooth calcification stages. Methods: The current study comprised of 405 subjects selected from orthodontic patients of Saudi origin coming to clinics of the specialized dental centers in western region of Saudi Arabia. Dental age was assessed according to the developmental stages of upper and lower third molars and skeletal maturation according to the cervical vertebrae maturation stage method. Statistical analysis was done using Kruskal-Wallis H, Mann-Whitney U test, Chi-Square test; t-test and Spearman correlation coefficient for inter group comparison. Results: The females were younger than males in all cervical stages. The CS1-CS2 show the period before the peak of growth, during CS3-CS5 it’s the pubertal growth spurt and CS6 is the period after the peak of the growth. The mean age and standard deviation for cervical stages of CS2, CS3 and CS4 were 12.09 ±1.72 years, 13.19 ±1.62 and 14.88 ±1.52 respectively. The Spearman correlation coefficients between cervical vertebrae and dental maturation were between 0.166 and 0.612, 0.243 and 0.832 for both sexes for upper and lower third molars. The significance levels for all coefficients were equal at 0.01 and 0.05. Conclusion: The results of this study showed that the skeletal maturity increased with the increase in dental ages for both genders. An early rate of skeletal maturation stage was observed in females. This study needs further analysis using a larger sample covering the entire dentition.

Low-effort thought promotes political conservatism.

Eidelman, Scott; Crandall, Christian S; Goodman, Jeffrey A; Blanchar, John C

2012-06-01

The authors test the hypothesis that low-effort thought promotes political conservatism. In Study 1, alcohol intoxication was measured among bar patrons; as blood alcohol level increased, so did political conservatism (controlling for sex, education, and political identification). In Study 2, participants under cognitive load reported more conservative attitudes than their no-load counterparts. In Study 3, time pressure increased participants' endorsement of conservative terms. In Study 4, participants considering political terms in a cursory manner endorsed conservative terms more than those asked to cogitate; an indicator of effortful thought (recognition memory) partially mediated the relationship between processing effort and conservatism. Together these data suggest that political conservatism may be a process consequence of low-effort thought; when effortful, deliberate thought is disengaged, endorsement of conservative ideology increases.

Inter-professional education (IPE) is recognised as a major way of introducing students in the health professions to the importance of teamwork and communication in the delivery of excellent healthcare. This pilot project evaluated mixed versus single discipline group tutorials of nursing and medical students as a way to promote IPE and understanding of communication. Four tutorial sessions were video-recorded and analysed using a video analysis coding grid. Additional data were drawn from student evaluations and assessment of group participation and were subjected to quantitative and qualitative analysis. The case study as portrayed in the DVD was thought to provide an effective learning tool by both sets of students. Medical students rated the need for mixed group tutorials significantly lower than the nursing students who thought the tutorial activity helped with an appreciation of the importance of communication to effective teamwork. However, medical students in the single discipline group did not understand the nursing role. The resources fostered reflection on student's own professional role as well as others; however, the importance of communication within the nursing role needs to be recognised by nursing students and curriculum designers.

Evidence in Practice section uses a standardized format enabling practitioners to share their experience of integrating research evidence into their practice. The final section of these brief articles asks the writers to reflect on their experience. Although it is not research, the individual reflection allies with what Schön (1983 called “reflection on action” and such reflections over time form a practical, tacit knowledge that we use to inform our work. Within this section of the journal, we hope readers will become more aware of how different types of evidence can be integrated into real‐world decision making. Not everything requires a full blown research study, and this section allows readers to see what other practitioners are doing, and in turn it should enable them to reflect upon what they are doing in their own practice. Being aware of situations where things may or may not have worked, and reflecting on the reasons why, brings together our sense of critical thought and practical experience that go a long way in filling the “librarian observed” and “professional judgements” parts of the EBLIP definition (Booth and Brice 2004. Acquiring professional knowledge does not end when we complete a graduate program, or have a certain number of years experience under our belts. It needs to be continually and consciously cultivated via reflection on our practice, our research, and simply what works and why. Research knowledge only takes us so far. People often ask me, “What do I do when there is no evidence? Or when the research evidence is weak?” Does this stop us from moving ahead? No. A decision still needs to be made. Evidence based practice is not only about acting when there is good evidence. Enhancing our professional judgments via a career built on analytical reflection, will provide knowledge that goes a long way towards making difficult decisions a little bit easier; even (or perhaps, especially in the cases when there is already a large body of

Full Text Available Counselling or prescribing drugs during pregnancy requires health professionals to assess risk/benefit ratio for women and their baby. A misperception of the risk may lead to inappropriate decisions for pregnancy outcomes. The aim of the present study was to assess teratogenic and/or foetotoxic risk perception of common medications by general practitioners (GPs and community pharmacists (CPs from the Midi-Pyrenees area.Methods: 103 GPs and 104 CPs were interviewed. For 21 given drugs, a visual-analogue scale was used to evaluate the risk to give birth to a malformed infant if the mother had taken the drug during first trimester of pregnancy. For 9 drugs, health professionals had to say if they thought there was a potential foetotoxic and/or neonatal risk when drugs were administered during late pregnancy.Results: 97% and 91% of GPs and CPs respectively thought that isotretinoin and thalidomide are teratogenic and more than 80% thought that amoxicillin and acetaminophen are safe in early pregnancy. However, 19% of the GPs and 33% of CPs answered there were no teratogenic risk for valproate. Around 11% of both GPs and CPs said that warfarin was safe during pregnancy. For 22% of GPs and for 13% and 27% of CPs respectively, ibuprofen and enalapril were safe on late pregnancy. For each drug, mean value of perceived teratogenic risk by health professionals was higher than values that can be found in scientific references. Concerning isotretinoin, thalidomide and metoclopramide, perceived teratogenic risk was higher for CPs.Conclusion: These data show that the potential teratogenic and foetotoxic risk of several commonly used drugs is unknown by health professionals. Conversely, GPs and CPs who think that a risk exists, overestimate it. This misperception can lead to inappropriate decisions for pregnancy outcomes.

Human dendritic cells sequentially matured with CD4(+) T cells as a secondary signal favor CTL and long-term T memory cell responses.

Dendritic cells (DCs) are professional antigen-presenting cells involved in the control and initiation of immune responses. In vivo, DCs exposed at the periphery to maturation stimuli migrate to lymph nodes, where they receive secondary signals from CD4+ T helper cells. These DCs become able to initiate CD8+ cytotoxic T lymphocyte (CTL) responses. However, in vitro investigations concerning human monocyte-derived DCs have never focused on their functional properties after such sequential maturation. Here, we studied human DC phenotypes and functions according to this sequential exposure to maturation stimuli. As first signals, we used TNF-α/polyI:C mimicking inflammatory and pathogen stimuli and, as second signals, we compared activated CD4+ T helper cells to a combination of CD40-L/ IFN-γ. Our results show that a sequential activation with activated CD4+ T cells dramatically increased the maturation of DCs in terms of their phenotype and cytokine secretion compared to DCs activated with maturation stimuli delivered simultaneously. Furthermore, this sequential maturation led to the induction of CTL with a long-term effector and central memory phenotypes. Thus, sequential delivery of maturation stimuli, which includes CD4+ T cells, should be considered in the future to improve the induction of long-term CTL memory in DC-based immunotherapy.

Thought-action fusion in individuals with OCD symptoms.

Rachman (Rachman, S. (1993). Obsessions, responsibility, and guilt. Behaviour Research and Therapy, 31, 149-154) suggested that patients with OCD may interpret thoughts as having special importance, thus experiencing thought-action fusion (TAF). Shafran, Thordarson and Rachman (Shafran, R., Thordarson, D. S. & Rachman, S. (1996). Thought-action fusion in obsessive compulsive disorder. Journal of Anxiety Disorders, 710, 379-391) developed a questionnaire (TAF) and found that obsessives scored higher than non-obsessives on the measure. In the current study, we modified the TAF to include a scale that assessed the "likelihood of events happening to others" as well as ratings of the responsibility and cost for having these thoughts. Replicating previous findings, we found that individuals with OC symptoms gave higher ratings to the likelihood of negative events happening as a result of their negative thoughts. Individuals with OC symptoms also rated the likelihood that they would prevent harm by their positive thoughts higher than did individuals without OC symptoms. These results suggest that the role of thought-action fusion in OCs may extend to exaggerated beliefs about thoughts regarding the reduction of harm.

Tropical anurans mature early and die young: Evidence from eight Afromontane Hyperolius species and a meta-analysis.

Directory of Open Access Journals (Sweden)

Ulrich Sinsch

Full Text Available Age- and size-related life-history traits of anuran amphibians are thought to vary systematically with latitude and altitude. Because the available data base is strongly biased towards temperate-zone species, we provide new estimates on eight afrotropical Reed Frog species. A meta-analysis of the demographic traits in 44 tropical anuran species aims to test for the predicted clinal variation and to contrast results with variation detected in temperate-zone species. The small-sized reed frogs reach sexual maturity during the first or second year of life, but longevity does not exceed three to four years. Latitudinal effects on demographic life-history traits are not detectable in tropical anurans, and altitudinal effects are limited to a slight size reduction at higher elevations. Common features of anuran life-history in the tropics are early sexual maturation at small size and low longevity resulting in low lifetime fecundity. This pattern contrasts with that found in temperate-zone anurans which mature later at larger size and grow considerably older yielding greater lifetime fecundity than in the tropics. Latitudinal and altitudinal contraction of the yearly activity period shape the evolution of life-history traits in the temperate region, while trait variation in the tropics seems to be driven by distinct, not yet identified selective forces.

One appears in the communication as one resorts for the social mobilization, towards the political pretensions of the messianic environmental thought, to symbiologies of body, psychic character and society of skeptical or relativist character. For the analysis of the symbiologies, we start from the criterion that when they are used politically in the environmental thought it is not done necessarily with an intention of strategic use I specify, but that its use can be by the implicit valuations that have these symbiologies in the world of the daily life, where the systems of environmental thought also interact of messianic type

2012-04-01

The purpose of this study was to determine the reliability of eccentric (ECC) and concentric (CON) kinematic and kinetic variables thought to be critical to jump performance during bilateral vertical countermovement jump (VCMJ) and horizontal countermovement jump (HCMJ) across children of different maturity status. Forty-two athletic male and female participants between 9 and 16 years of age were divided into 3 maturity groups according to peak height velocity (PHV) offset (Post-PHV, At-PHV, and Pre-PHV) and percent of predicted adult stature. All the participants performed 3 VCMJ and HCMJ trials and the kinematics, and kinetics of these jumps were measured via a force plate over 3 testing sessions. In both jumps, vertical CON mean and peak power and jump height or distance were the most reliable measures across all groups (change in the mean [CM] = -5.4 to 6.2%; coefficient of variation [CV] = 2.1-9.4%; Intraclass correlation coefficient [ICC] = 0.82-0.98), whereas vertical ECC mean power was the only ECC variable with acceptable reliability for both jumps (CM = -0.7 to 10.1%; CV = 5.2-15.6%; ICC = 0.74-0.97). A less mature state was "likely" to "very likely" to reduce the reliability of the HCMJ ECC kinetics and kinematics. These findings suggested that movement variability is associated with the ECC phase of CMJs, especially in Pre-PHV during the HCMJ. Vertical CON mean and peak power and ECC mean power were deemed reliable and appropriate to be used in children as indicators of jump and stretch-shortening cycle performance.

Thought Suppression Research Methods: Paradigms, Theories, Methodological Concerns

Full Text Available It is hard to provide an unequivocal answer to the question of whether or not thought suppression is effective. Two thought suppression paradigms - the “white bear” paradigm and the think/no-think paradigm - give mixed results. Generally, “white bear” experiments indicate that thought suppression is counterproductive, while experiments in the think/no-think paradigm suggest that it is possible to effectively suppress a thought. There are also alternative methods used to study thought suppression, for instance the directed forgetting paradigm or the Stroop task. In the article, I describe the research methods used to explore thought suppression efficacy. I focus on the “white bear” and the think/no-think paradigms and discuss theories proposed to explain the results obtained. I also consider the internal and external validity of the methods used.

Naturally Engineered Maturation of Cardiomyocytes

Directory of Open Access Journals (Sweden)

Gaetano J. Scuderi

2017-05-01

Full Text Available Ischemic heart disease remains one of the most prominent causes of mortalities worldwide with heart transplantation being the gold-standard treatment option. However, due to the major limitations associated with heart transplants, such as an inadequate supply and heart rejection, there remains a significant clinical need for a viable cardiac regenerative therapy to restore native myocardial function. Over the course of the previous several decades, researchers have made prominent advances in the field of cardiac regeneration with the creation of in vitro human pluripotent stem cell-derived cardiomyocyte tissue engineered constructs. However, these engineered constructs exhibit a functionally immature, disorganized, fetal-like phenotype that is not equivalent physiologically to native adult cardiac tissue. Due to this major limitation, many recent studies have investigated approaches to improve pluripotent stem cell-derived cardiomyocyte maturation to close this large functionality gap between engineered and native cardiac tissue. This review integrates the natural developmental mechanisms of cardiomyocyte structural and functional maturation. The variety of ways researchers have attempted to improve cardiomyocyte maturation in vitro by mimicking natural development, known as natural engineering, is readily discussed. The main focus of this review involves the synergistic role of electrical and mechanical stimulation, extracellular matrix interactions, and non-cardiomyocyte interactions in facilitating cardiomyocyte maturation. Overall, even with these current natural engineering approaches, pluripotent stem cell-derived cardiomyocytes within three-dimensional engineered heart tissue still remain mostly within the early to late fetal stages of cardiomyocyte maturity. Therefore, although the end goal is to achieve adult phenotypic maturity, more emphasis must be placed on elucidating how the in vivo fetal microenvironment drives cardiomyocyte

The maturing of microbial ecology.

Schmidt, Thomas M

2006-09-01

A.J. Kluyver and C.B. van Niel introduced many scientists to the exceptional metabolic capacity of microbes and their remarkable ability to adapt to changing environments in The Microbe's Contribution to Biology. Beyond providing an overview of the physiology and adaptability of microbes, the book outlined many of the basic principles for the emerging discipline of microbial ecology. While the study of pure cultures was highlighted, provided a unifying framework for understanding the vast metabolic potential of microbes and their roles in the global cycling of elements, extrapolation from pure cultures to natural environments has often been overshadowed by microbiologists inability to culture many of the microbes seen in natural environments. A combination of genomic approaches is now providing a culture-independent view of the microbial world, revealing a more diverse and dynamic community of microbes than originally anticipated. As methods for determining the diversity of microbial communities become increasingly accessible, a major challenge to microbial ecologists is to link the structure of natural microbial communities with their functions. This article presents several examples from studies of aquatic and terrestrial microbial communities in which culture and culture-independent methods are providing an enhanced appreciation for the microbe's contribution to the evolution and maintenance of life on Earth, and offers some thoughts about the graduate-level educational programs needed to enhance the maturing field of microbial ecology.

Primary care interventions to reduce childhood obesity and sugar-sweetened beverage consumption: Food for thought for oral health professionals.

Childhood obesity remains a significant threat to America's children. Health care leaders have increasingly called upon oral health professionals to integrate healthy weight promotion and enhanced sugar-sweetened beverage counseling into their professional practices. The aim of this scoping review is to examine recent evidence regarding the effectiveness of primary care childhood obesity interventions that have potential for adoption by oral health professionals. Medine, and PubMed were searched from 2010 to 2016 for review articles and studies reporting patient outcomes or policy outcomes relevant to primary care childhood obesity interventions for children ages 2-11 years. Additional articles were accessed through relevant websites, journals, and references. Our screening criteria included interventions that could be adopted by oral health professionals. Forty-two articles met inclusion criteria. Effective interventions fell into four domains: family-based programs, motivational interviewing, office-based practice tools, and policy interventions. Despite strong evidence linking the consumption of sugar-sweetened beverages to childhood obesity, our review did not find evidence of primary care programs effectively targeting and reducing childhood sugary drinks. Effective primary care interventions for addressing childhood obesity have been identified, although only short-term effectiveness has been demonstrated. Dissemination of these practices as well as further research and advocacy are needed. Childhood obesity and poor oral health share many common risk factors. Additional research should focus on the benefits and feasibility of widespread interdisciplinary medical-oral health collaboration in addressing the two most prevalent diseases of childhood. © 2017 American Association of Public Health Dentistry.

The contribution of thought-action fusion and thought suppression in the development of obsession-like intrusions in normal participants.

Science.gov (United States)

Rassin, E

2001-09-01

Both thought-action fusion (TAF: i.e., a cognitive bias implying an inflated sense of responsibility for one's own thoughts) and thought suppression have been claimed to contribute to the development of obsession-like intrusions. Therefore, it seems plausible that conjunction of these phenomena results in highly intense intrusions. However, possible interactions between TAF and thought suppression have not yet been investigated experimentally. In the current study, healthy volunteers were exposed to a TAF-like intrusion. They were, then, randomly assigned to a suppression (n=21) or non-suppression condition (n=19). Next, visual analogue scales (VASs) were completed measuring anxiety, feelings of responsibility and guilt, urge to neutralise and so on. Contrary to expectation, several VAS scores were lower for participants in the suppression group than for those in the non-suppression group. Hence, it is concluded that thought suppression may, at least in the short term, alleviate discomfort caused by TAF-like intrusions.

Acharan sulfate isolated from the giant African snail, Achatina fulica, has been reported to have antitumor activity in vivo. In an effort to determine the mechanisms of its antitumor activity, we examined the effects of acharan sulfate on professional antigen presenting cells (APCs). Acharan sulfate increased the phagocytic activity, the production of cytokines such as TNF-alpha and IL-1beta, and the release of nitric oxide on a macrophage cell line, Raw 264.7 cells. In addition, acharan sulfate induced phenotypic and functional maturation of immature dendritic cells (DCs). Immature DCs cultured with acharan sulfate expressed higher levels of class II MHC molecules and major co-stimulatory molecules such as B7-1, B7-2, and CD40. Functional maturation of immature DCs cultured in the presence of acharan sulfate was confirmed by the increased allostimulatory capacity and IL-12 production. These results suggest that the antitumor activity of acharan sulfate is partly due to the activation of professional antigen presenting cells.

Against dichotomies: On mature care and self-sacrifice in care ethics.

Science.gov (United States)

van Nistelrooij, Inge; Leget, Carlo

2017-09-01

In previous issues of this journal, Carol Gilligan's original concept of mature care has been conceptualized by several (especially Norwegian) contributors. This has resulted in a dichotomous view of self and other, and of self-care and altruism, in which any form of self-sacrifice is rejected. Although this interpretation of Gilligan seems to be quite persistent in care-ethical theory, it does not seem to do justice to either Gilligan's original work or the tensions experienced in contemporary nursing practice. A close reading of Gilligan's concept of mature care leads to a view that differs radically from any dichotomy of self-care and altruism. Instead of a dichotomous view, a dialectical view on self and other is proposed that builds upon connectedness and might support a care-ethical view of nursing that is more consistent with Gilligan's own critical insights such as relationality and a practice-based ethics. A concrete case taken from nursing practice shows the interconnectedness of professional and personal responsibility. This underpins a multilayered, complex view of self-realization that encompasses sacrifices as well. When mature care is characterized as a practice of a multilayered connectedness, caregivers can be acknowledged for their relational identity and nursing practices can be recognized as multilayered and interconnected. This view is better able to capture the tensions that are related to today's nursing as a practice, which inevitably includes sacrifices of self. In conclusion, a further discussion on normative conceptualizations of care is proposed that starts with a non-normative scrutiny of caring practices.

Human dendritic cells sequentially matured with CD4+ T cells as a secondary signal favor CTL and long-term T memory cell responses

Directory of Open Access Journals (Sweden)

Thomas Simon

2012-01-01

Full Text Available Dendritic cells (DCs are professional antigen-presenting cells involved in the control and initiation of immune responses. In vivo, DCs exposed at the periphery to maturation stimuli migrate to lymph nodes, where they receive secondary signals from CD4+ T helper cells. These DCs become able to initiate CD8+ cytotoxic T lymphocyte (CTL responses. However, in vitro investigations concerning human monocyte-derived DCs have never focused on their functional properties after such sequential maturation. Here, we studied human DC phenotypes and functions according to this sequential exposure to maturation stimuli. As first signals, we used TNF-α/polyI:C mimicking inflammatory and pathogen stimuli and, as second signals, we compared activated CD4+ T helper cells to a combination of CD40-L/ IFN-γ. Our results show that a sequential activation with activated CD4+ T cells dramatically increased the maturation of DCs in terms of their phenotype and cytokine secretion compared to DCs activated with maturation stimuli delivered simultaneously. Furthermore, this sequential maturation led to the induction of CTL with a long-term effector and central memory phenotypes. Thus, sequential delivery of maturation stimuli, which includes CD4+ T cells, should be considered in the future to improve the induction of long-term CTL memory in DC-based immunotherapy.

Cervical vertebral maturation as a biologic indicator of skeletal maturity.

To identify and review the literature regarding the reliability of cervical vertebrae maturation (CVM) staging to predict the pubertal spurt. The selection criteria included cross-sectional and longitudinal descriptive studies in humans that evaluated qualitatively or quantitatively the accuracy and reproducibility of the CVM method on lateral cephalometric radiographs, as well as the correlation with a standard method established by hand-wrist radiographs. The searches retrieved 343 unique citations. Twenty-three studies met the inclusion criteria. Six articles had moderate to high scores, while 17 of 23 had low scores. Analysis also showed a moderate to high statistically significant correlation between CVM and hand-wrist maturation methods. There was a moderate to high reproducibility of the CVM method, and only one specific study investigated the accuracy of the CVM index in detecting peak pubertal growth. This systematic review has shown that the studies on CVM method for radiographic assessment of skeletal maturation stages suffer from serious methodological failures. Better-designed studies with adequate accuracy, reproducibility, and correlation analysis, including studies with appropriate sensitivity-specificity analysis, should be performed.

Correlation between chronological age, cervical vertebral maturation and Fishman's skeletal maturity indicators in southern Chinese.

2008-07-01

To investigate the correlation between chronological age, cervical vertebral maturation (CVM), and Fishman's hand-wrist skeletal maturity indicators in southern Chinese. Four hundred contemporary hand-wrist and lateral cephalometric radiographs of southern Chinese subjects were randomly selected and analyzed. The female subjects were between 10 and 15 years of age, and the male subjects were between 12 and 17 years of age; all subjects were within the circumpubertal period. The CVM was assessed using the method developed by Baccetti and coworkers, but the hand-wrist maturation was assessed using the method developed by Fishman. These two methods and the chronological age were correlated using the Spearman rank correlation analysis. The CVM was significantly correlated with the hand-wrist skeletal age (Spearman r male = 0.9206, female = 0.9363). All patients in the cervical maturation stage (CS3) of CVM were discovered to be in the skeletal maturational indicator (SMI2 or SMI3) stages of hand-wrist maturation (HWM), which was around the peak of the growth spurt. Low correlations were found between the CVM and chronological age (male r = 0.7577; female r = 0.7877) and between the HWM and chronological age (male r = 0.7492; female r = 0.7758). CVM is a valid indicator of skeletal growth during the circumpubertal and has a high correlation with the HWM for the southern Chinese population. However, the low correlations found between the chronological age and both CVM and HWM showed that the chronological age was not suitable to measure skeletal maturity.

'I'm actually being the grown-up now': leadership, maturity and professional identity development.

This study reports on an evaluation of an in-house nursing and midwifery leadership programme within a New Zealand District Health Board aimed at improving leadership capacity within clinical environments. The programme associated with this study is based on Practice Development concepts which aim to improve patient care and service delivery as well as empower practitioners to foster and support a transformational culture. Mixed methods were used. Evidence indicated participants' self-confidence improved leading to a 'growing up'. This was demonstrated in a number of ways: taking more responsibility for individual clinical practice, undertaking quality and safety roles as well as postgraduate study. These findings can be constructed in terms of linking leadership training with the development of professional identity. This study provides evidence that in-house leadership programmes can provide front-line nurses and midwives with opportunities to enhance their professional identity and expand their skills in a variety of ways. Organisational investment in in-house programmes aimed at leadership skills have the potential to enhance patient care as well as improve the work environment for nurses and midwives. However, in-house programmes should be considered as augmenting rather than replacing tertiary education institutions' leadership courses and qualifications. © 2013 John Wiley & Sons Ltd.

Conventional MR imaging findings of human brain development are thought to result from decreasing water content, increasing macromolecular concentration, and myelination. We use diffusion-tensor MR imaging to test theoretical models that incorporate hypotheses regarding how these maturational processes influence water diffusion in developing gray and white matter. Experimental data were derived from diffusion-tensor imaging of 167 participants, ages 31 gestational weeks to 11 postnatal years. An isotropic diffusion model was applied to the gray matter of the basal ganglia and thalamus. A model that assumes changes in the magnitude of diffusion while maintaining cylindrically symmetric anisotropy was applied to the white matter of the corpus callosum and internal capsule. Deviations of the diffusion tensor from the ideal model predictions, due to measurement noise, were estimated by using Monte Carlo simulations. Developing gray matter of the basal ganglia and developing white matter of the internal capsule and corpus callosum largely conformed to theory, with only small departures from model predictions in older children. However, data from the thalamus substantially diverged from predicted values, with progressively larger deviations from the model with increasing participant age. Changes in water diffusion during maturation of central gray and white matter structures can largely be explained by theoretical models incorporating simple assumptions regarding the influence of brain water content and myelination, although deviations from theory increase as the brain matures. Diffusion-tensor MR imaging is a powerful method for studying the process of brain development, with both scientific and clinical applications.

Fast thought speed induces risk taking.

In two experiments, we tested for a causal link between thought speed and risk taking. In Experiment 1, we manipulated thought speed by presenting neutral-content text at either a fast or a slow pace and having participants read the text aloud. In Experiment 2, we manipulated thought speed by presenting fast-, medium-, or slow-paced movie clips that contained similar content. Participants who were induced to think more quickly took more risks with actual money in Experiment 1 and reported greater intentions to engage in real-world risky behaviors, such as unprotected sex and illegal drug use, in Experiment 2. These experiments provide evidence that faster thinking induces greater risk taking.

Conscious and unconscious thought in risky choice: Testing the capacity principle and the appropriate weighting principle of Unconscious Thought Theory

Directory of Open Access Journals (Sweden)

Nathaniel James Siebert Ashby

2011-10-01

Full Text Available Daily we make decisions ranging from the mundane to the seemingly pivotal that shape our lives. Assuming rationality, all relevant information about one’s options should be thoroughly examined in order to make the best choice. However, some findings suggest that under specific circumstances thinking too much has disadvantageous effects on decision quality and that it might be best to let the unconscious do the busy work. In three studies we test the capacity assumption and the appropriate weighting principle of unconscious thought theory using a classic risky choice paradigm and including a ‘deliberation with information’ condition. Although we replicate an advantage for unconscious thought over ‘deliberation without information’, we find that ‘deliberation with information’ equals or outperforms unconscious thought in risky choices. These results speak against the generality of the assumption that unconscious thought has a higher capacity for information integration and show that this capacity assumption does not hold in all domains. We furthermore show that ‘deliberate thought with information’ leads to more differentiated knowledge compared to unconscious thought which speaks against the generality of the appropriate weighting assumption.

2002-07-01

A senior physician with a government role in Japan made a widely reported and misleading statement about Thailand's policy on HIV/AIDS patients. He claimed that in Thailand the policy is to spend public money on the prevention of HIV infection while allowing AIDS patients to die untreated. The author, a community nursing specialist in Japan with first-hand knowledge of HIV/AIDS policy in Thailand, thought that this statement would influence attitudes negatively in Japan. However, speaking out about this misrepresentation of the facts carried certain risks. Although freedom of expression is valued in Japan, in practice it is not easy to contradict senior medical professionals. The author uses his experience of this difficult professional situation to teach nurses how to approach speaking out in the public interest.

Infection of chickens with virulent Newcastle disease virus (NDV) is associated with severe pathology and increased morbidity and mortality. The innate immune response contributes to the pathogenicity of NDV. As professional antigen-presenting cells, dendritic cells (DCs) play a unique role in innate immunity. However, the contribution of DCs to NDV infection has not been investigated in chickens. In this study, we selected two representative NDV strains, i.e., the velogenic NDV strain Chicken/Guangdong/GM/2014 (GM) and the lentogenic NDV strain La Sota, to investigate whether NDVs could infect LPS-activated chicken bone-derived marrow DCs (mature chicken BM-DCs). We compared the viral titres and innate immune responses in mature chicken BM-DCs following infection with those strains. Both NDV strains could infect mature chicken BM-DC, but the GM strain showed stronger replication capacity than the La Sota strain in mature chicken BM-DCs. Gene expression profiling showed that MDA5, LGP2, TLR3, TLR7, IFN-α, IFN-β, IFN-γ, IL-1β, IL-6, IL-18, IL-8, CCL5, IL-10, IL-12, MHC-I, and MHC-II levels were altered in mature DCs after infection with NDVs at all evaluated times postinfection. Notably, the GM strain triggered stronger innate immune responses than the La Sota strain in chicken BM-DCs. However, both strains were able to suppress the expression of some cytokines, such as IL-6 and IFN-α, in mature chicken DCs at 24 hpi. These data provide a foundation for further investigation of the role of chicken DCs in NDV infection.

Digital professionalism is increasingly being integrated into postgraduate medical education. We developed a small-group, reflective practice-based session incorporating radiology-specific cases to heighten residents' awareness about digital professionalism. Case-based, radiology-specific scenarios were created for a small-group, reflective practice-based session on digital professionalism. Anonymous pre- and postsession surveys evaluating residents' use of social media and their thoughts about the session were administered to the radiology residents. Twenty-five of 38 (66%) residents responded to the presession survey with 40% (10/25) reporting daily social media use; 50% (12/24) witnessing an unprofessional posting on Facebook; and 8% (2/25) posting something unprofessional themselves. Of the 21 residents who attended the session, 13 (62%) responded to the postsession survey. Residents reported that the session added to their understanding of professionalism 3.92, 95% CI (3.57-4.27). As a result of the session, residents stated that they were more aware of protecting patient privacy and confidentiality on social media sites 3.92, 95% CI (3.47-4.37), and would take a more active role in ensuring professional use of social media as it relates to patient care 4.00, 95% CI (3.66-4.34). Residents favorably viewed the reflective case-based session on digital professionalism as a means to be more aware of ways to avoid unprofessional interactions on the internet. Our results suggest that such reflective sessions are an effective method to educate residents on key concepts regarding digital professionalism. Copyright © 2012 AUR. Published by Elsevier Inc.

Physicians in both Western and Eastern countries are being confronted by changes in health care delivery systems and medical professionalism values. The traditional concept of "In-Sul" (benevolent art) and the modern history of South Korea have led to cultural differences between South Korea and other countries in conceptualizing medical professionalism; thus, we studied medical students' perceptions of professionalism as described in essays written on this topic. In 2014, we asked 109 first-year medical students who were enrolled in a compulsory ethics course to anonymously write a description of an instance of medical professionalism that they had witnessed, as well as reflecting on their own professional context. We then processed 105 valid essays using thematic content analysis with computer-assisted qualitative data analysis software. Thematic analysis of the students' essays revealed two core aspects of professionalism in South Korea, one focused on respect for patients and the other on physicians' accountability. The most common theme regarding physician-patient relationships was trust. By contrast, distributive justice was thought to be a non-essential aspect of professionalism. In Western countries, physicians tend to promote justice in the health care system, including fair distribution of medical resources; however, we found that medical students in South Korea were more inclined to emphasize doctors' relationships with patients. Medical educators should develop curricular interventions regarding medical professionalism to meet the legitimate needs of patients in their own culture. Because professionalism is a dynamic construct of culture, medical educators should reaffirm cultural context-specific definitions of professionalism for development of associated curricula.

Perceived stops to suicidal thoughts, plans, and actions in persons experiencing psychosis.

Suicide has been conceived as involving a continuum, whereby suicidal plans and acts emerge from thoughts about suicide. Suicide prevention strategies need to determine whether different responses are needed at these points on the continuum. This study investigates factors that were perceived to counter suicidal ideation, plans, and acts. The 36 participants, all of whom had had experiences of psychosis and some level of suicidality, were presented with a vignette describing a protagonist with psychotic symptoms. They were asked to indicate what would counter the suicidal thoughts, plans, and acts of the protagonist described in the vignette. Qualitative techniques were first used to code these free responses into themes/categories. Correspondence analysis was then applied to the frequency of responses in each of these categories. Social support was identified as a strong counter to suicidal ideation but not as a counter to suicidal plans or acts. Help from health professionals was strongly related to the cessation of suicidal plans as were the opinions of the protagonist's children. Changing cognitions and strengthening psychological resources were more weakly associated with the cessation of suicidal ideation and plans. The protagonist's children were considered potentially helpful in addressing suicidal acts. These results suggest that both overlapping and nonoverlapping factors need to be considered in understanding suicide prevention, dependent on whether individuals are thinking about, planning, or attempting suicide.

Sustaining Exploration in Mature Basins

International Nuclear Information System (INIS)

Bayo, A.

2002-01-01

Exploration is a business like any other business driven by opportunity, resources and expectation of profit. Therefore, exploration will thrive anywhere the opportunities are significant, the resources are available and the outlook for profit (or value creation) is good. To sustain exploration activities anywhere, irrespective of the environment, there must be good understanding of the drivers of these key investment criteria. This paper will examine these investment criteria as they relate to exploration business and address the peculiarity of exploration in mature basin. Mature basins are unique environment that lends themselves a mix of fears, paradigms and realities, particularly with respect to the perception of value. To sustain exploration activities in a mature basin, we need to understand these perceptions relative to the true drivers of profitability. Exploration in the mature basins can be as profitable as exploration in emerging basins if the dynamics of value definition-strategic and fiscal values are understood by operators, regulators and co ventures alike. Some suggestions are made in this presentation on what needs to be done in addressing these dynamic investment parameters and sustaining exploration activities in mature basins

This article investigates 2 possible antecedents of thought confidence and explores the effects of confidence induced before or during ad exposure. The results of the experiments indicate that both consumers' dispositional optimism and spokesperson attractiveness have significant effects on consumers' confidence in thoughts that are generated after viewing the advertisement. Higher levels of thought confidence will influence the quality of the thoughts that people generate, lead to either positively or negatively polarized message processing, and therefore induce better or worse advertising effectiveness, depending on the valence of thoughts. The authors posit the belief-polarization hypothesis to explain these findings.

Role of thought-related beliefs and coping strategies in the escalation of intrusive thoughts: an analog to obsessive-compulsive disorder.

Science.gov (United States)

Marcks, Brook A; Woods, Douglas W

2007-11-01

Cognitive-behavioral models of obsessive-compulsive disorder (OCD) assume that obsessions have their origin in normal intrusive thoughts. These models propose that certain beliefs, such as thought-action fusion (TAF) beliefs, combined with the use of ineffective coping strategies, such as thought suppression, lead to the development of OCD. The purpose of the current study was to examine the relationship between these variables in a non-clinical sample in addition to exploring the effects of an alternative, acceptance-based coping strategy. This study explored the relationship between TAF beliefs, thought suppression, and OC-consistent symptoms via mediational analyses. Results showed that thought suppression mediated the relationship between TAF beliefs and OC-consistent symptoms. This study also experimentally examined the effects of various coping strategies (suppression, acceptance, or monitor-only) on the frequency of a distressing intrusion and appraisal ratings (e.g., anxiety, guilt, responsibility) after a TAF induction. Spontaneous suppression in the monitor-only group made comparisons of the experimental data difficult. However, analyses provided preliminary evidence suggesting that thought suppression is related to more intrusions, higher levels of anxiety, and negative appraisals, whereas an acceptance-based approach may be a useful alternative. Additional findings, limitations of the current study, and directions for future research are discussed.

Full Text Available Thought is considered a psychological concept associated with an individual’s mental ex- istence. It is apparent that a great deal of research has been focused on thought as an area of study. however, there is no psychological theory of thought which provides an expla- nation for its nature and structural organization. So far, researchers have mainly looked at the ways this concept is expressed, rather than investigating what it actually is. In this study, however, based on studies of the functions of the psyche, mental processes, and the neurophysiological bases of mental activity, thought is identified as a need-emotion- intentional substance existing in the human being’s inner world. In keeping with this understanding of thought, the hypothesis that thought generation is caused by desire and experience (feeling and emotion is put forward. An individual’s thought is linked to his behavior or motivation for activity, and is followed by an emotional experience. The process of thought generation is regarded through the mechanism of behavioral motiva- tion. The primary purpose of this mechanism is to define the qualities of the external objects that serve for need satisfaction and functionality in individuals. The ability to generate thoughts is a feature of thinking related to an individual’s mental ability or frame of mind. From this standpoint, a person’s mentality is considered to be the capacity of the individual to generate thoughts and work through thoughts. It is shown that the abil- ity to generate thoughts and establish relationships within a stream of consciousness is characteristic of human intelligence. Some basic propositions toward a development of a psychological theory of thought are introduced.

The application of postmodern thought to the clinical practice of psychoanalytic psychotherapy.

Science.gov (United States)

Chessick, R D

1996-01-01

The purpose of this article has been to acquaint psychoanalysts and psychoanalytically oriented psychotherapists with some of the most current ideas in philosophy and psychology, which have crucial implications for our professional organizations and our clinical work. The basic stance of this postmodern thinking constitutes a challenge to what is called foundationalism, which dominated scientific and philosophical thought until recently. In place of foundationalism, even in the production of scientific or philosophical works, we could hope for an ongoing dialogue between a king or queen who states the basic theoretical orientation, the loyal opposition that looks for inconsistencies and kinks in it, the jester who deconstructs the whole thing and introduces parenthetical digressions, and finally, a secret society of organization that functions to hold the adherents of the theory together and provide them with a unifying ego ideal. Postmodern thought is described and there is some discussion of its "four horsemen," Derrida, Rorty, Foucault, and Lyotard, who in general question the possibility of whether any form of interpretation can be thought of as related to reality or the truth. My own point of view is that an intermediate position is necessary rather than a binary opposition between nihilism and foundationalism or more specifically, postmodernism and traditional psychoanalysis. That is to say, within certain horizons and with an understanding of the cultural and historical referents that always affect and delimit both the patient and the therapist, it is still possible to reach conceptions about what is going on both in the psychoanalytic process and the psyche of the patient that have at least a tentative "truth." Careful attention to the patient's material following an interpretation can provide clues about the validity of our conception at the time. But the horizons and historicity that delimit all "truth" reduce the authority and the stature of the analyst

Thought Speed, Mood, and the Experience of Mental Motion.

Science.gov (United States)

Pronin, Emily; Jacobs, Elana

2008-11-01

This article presents a theoretical account relating thought speed to mood and psychological experience. Thought sequences that occur at a fast speed generally induce more positive affect than do those that occur slowly. Thought speed constitutes one aspect of mental motion. Another aspect involves thought variability, or the degree to which thoughts in a sequence either vary widely from or revolve closely around a theme. Thought sequences possessing more motion (occurring fast and varying widely) generally produce more positive affect than do sequences possessing little motion (occurring slowly and repetitively). When speed and variability oppose each other, such that one is low and the other is high, predictable psychological states also emerge. For example, whereas slow, repetitive thinking can prompt dejection, fast, repetitive thinking can prompt anxiety. This distinction is related to the fact that fast thinking involves greater actual and felt energy than slow thinking does. Effects of mental motion occur independent of the specific content of thought. Their consequences for mood and energy hold psychotherapeutic relevance. © 2008 Association for Psychological Science.

Bicarbonate Transport During Enamel Maturation.

Science.gov (United States)

Yin, Kaifeng; Paine, Michael L

2017-11-01

Amelogenesis (tooth enamel formation) is a biomineralization process consisting primarily of two stages (secretory stage and maturation stage) with unique features. During the secretory stage, the inner epithelium of the enamel organ (i.e., the ameloblast cells) synthesizes and secretes enamel matrix proteins (EMPs) into the enamel space. The protein-rich enamel matrix forms a highly organized architecture in a pH-neutral microenvironment. As amelogenesis transitions to maturation stage, EMPs are degraded and internalized by ameloblasts through endosomal-lysosomal pathways. Enamel crystallite formation is initiated early in the secretory stage, however, during maturation stage the more rapid deposition of calcium and phosphate into the enamel space results in a rapid expansion of crystallite length and mineral volume. During maturation-stage amelogenesis, the pH value of enamel varies considerably from slightly above neutral to acidic. Extracellular acid-base balance during enamel maturation is tightly controlled by ameloblast-mediated regulatory networks, which include significant synthesis and movement of bicarbonate ions from both the enamel papillary layer cells and ameloblasts. In this review we summarize the carbonic anhydrases and the carbonate transporters/exchangers involved in pH regulation in maturation-stage amelogenesis. Proteins that have been shown to be instrumental in this process include CA2, CA6, CFTR, AE2, NBCe1, SLC26A1/SAT1, SLC26A3/DRA, SLC26A4/PDS, SLC26A6/PAT1, and SLC26A7/SUT2. In addition, we discuss the association of miRNA regulation with bicarbonate transport in tooth enamel formation.

A comparison of 121 mature-age and 270 normal-age entrants who graduated from the University of Queensland Medical School between 1972 and 1987 shows that mature-age entrants are some 7 years older, are more likely to come from public (state) schools and less likely to have parents in professional/technical occupations. Otherwise, the two groups were similar in terms of gender, marital status, number of children, ethnic background and current practice location. The educational background of mature-age entrants prior to admission includes 44.6% with degrees in health-science areas and 31.4% with degrees in non-health areas. Reasons for delayed entry of mature-age entrants include late consideration of medicine as a career (34.7%), financial problems (31.4%), dissatisfaction with previous career (30.6%), poor academic results (19.8%), or a combination of the above factors. Motivations to study medicine include family influences (more so in normal-age entrants), altruistic reasons (more so in mature-age entrants) and a variety of personal/social factors such as intellectual satisfaction, prestige and financial security (similar for both groups) and parental expectations (more so in normal-age entrants). Mature-age entrants experienced greater stress throughout the medical course, especially with regard to financial difficulties, loneliness/isolation from the students and family problems (a greater proportion were married with children). While whole-course grades were similar in both groups, normal-age entrants tended to win more undergraduate honours/prizes and postgraduate diplomas/degrees, including specialist qualifications. Practice settings were similar in terms of group private practice, hospital/clinic practice or medical administration, but there was a greater proportion of mature-age entrants in solo private practice, and a smaller proportion in teaching/research. If given the time over, some two-thirds of both groups would choose medicine as a career

The purpose of this study was to predict the skeletal maturation status based on the assessment of cervical vertebrae from lateral cephalometric radiographs and to compare these findings with the skeletal maturity of the same individuals judged from the hand-wrist radiographs. Lateral cephalometric and left hand-wrist radiographs of 393 Caucasian children from 8 to 18 years old were evaluated. On the hand-wrist radiographs the classification of Bjork [1972] and Grave and Brown [1976] was used to assess skeletal maturity (HWSS). Cervical vertebral maturation was also evaluated on lateral cephalometric radiographs using the improved CVMS method described by Baccetti, Franchi, and McNamara [2002]. These methods were correlated using the chi-square test. The chi-square test showed that skeletal maturational values obtained by the CVMS method were significantly correlated with the skeletal values obtained from the hand-wrist analysis for both genders (pmaturity.

Fatigue among truck drivers has been studied extensively; however, less is known regarding the fatigue experience of taxi drivers in heavily populated metropolitan areas. This study aimed to compare the differences and similarities between truck and taxi driver fatigue to provide implications for the fatigue management and education of professional drivers. A sample of 274 truck drivers and 286 taxi drivers in Beijing was surveyed via a questionnaire, which included items regarding work characteristics, fatigue experience, accident information, attitude toward fatigue, and methods of counteracting fatigue. Driver fatigue was prevalent among professional drivers, and it was even more serious for taxi drivers. Taxi drivers reported more frequent fatigue experiences and were involved in more accidents. Among the contributing factors to fatigue, prolonged driving time was the most important factor identified by both driver groups. Importantly, the reason for the engagement in prolonged driving was neither due to the lack of awareness concerning the serious outcome of fatigue driving nor because of their poor detection of fatigue. The most probable reason was the optimism bias, as a result of which these professional drivers thought that fatigue was more serious for other drivers than for themselves, and they thought that they were effective in counteracting the effect of fatigue on their driving performance. Moreover, truck drivers tended to employ methods that require stopping to counteract fatigue, whereas taxi drivers preferred methods that were simultaneous with driving. Although both driver groups considered taking a nap as one of the most effective means to address fatigue, this method was not commonly used. Interestingly, these drivers were aware that the methods they frequently used were not the most effective means to counteract fatigue. This study provides knowledge on truck and taxi drivers' characteristics in fatigue experience, fatigue attitude, and

To evaluate cognitive theories of obsessions, the current study experimentally manipulated appraisals of the importance of intrusive thoughts. Undergraduate students (N = 156) completed measures of obsessive-compulsive disorder (OCD) symptoms and beliefs and were primed with a list of commonly reported unwanted thoughts. Participants were then informed that unwanted thoughts are either (1) significant and indicative of their personal values, or (2) meaningless, or participants (3) received no instructions about unwanted thoughts. Participants then completed implicit and explicit measures of self-evaluation and interpretations of their unwanted thoughts. Results indicated that the manipulation shifted implicit appraisals of unwanted thoughts in the expected direction, but not self-evaluations of morality or dangerousness. Interestingly, explicit self-esteem and beliefs about the significance of unwanted thoughts were associated with measures of OCD beliefs, whereas implicit self-evaluations of dangerousness were better predicted by the interaction of pre-existing OCD beliefs with the manipulation. Results are discussed in terms of divergent predictors of implicit and explicit responses to unwanted thoughts.

The relationship between culture, language, and thought has long been one of the most important topics for those who wish to understand the nature of human cognition. This issue has been investigated for decades across a broad range of research disciplines. However, there has been scant communication across these different disciplines, a situation largely arising through differences in research interests and discrepancies in the definitions of key terms such as 'culture,' 'language,' and 'thought.' This article reviews recent trends in research on the relation between language, culture and thought to capture how cognitive psychology and cultural psychology have defined 'language' and 'culture,' and how this issue was addressed within each research discipline. We then review recent research conducted in interdisciplinary perspectives, which directly compared the roles of culture and language. Finally, we highlight the importance of considering the complex interplay between culture and language to provide a comprehensive picture of how language and culture affect thought.

The rapid emergence of social media, including Facebook and YouTube, have added a new dimension to defining, teaching, and role modeling professionalism in the medical field. Explicit and consistent role modeling of professional behaviors are needed to encourage the development of professional physicians. The purpose of this article is to investigate the challenges and opportunities at the interface of professionalism and social media for physicians. The medical literature via PubMed was reviewed with key words including "Facebook," "YouTube," "social media," "digital media," and key issues are discussed. Our residency program was surveyed regarding their experiences with digital media in medical practice and the findings are discussed. Sample topics and relevant, thought provoking questions generated from our practices are outlined. Case vignettes are offered to exemplify issues with regard to professionalism raised by digital and social media in medical practice. Social media sites offer great opportunity to widely distribute valuable health care information as well as provide physicians with a venue to de-stress. In this new digital age, trainees and lifelong learners must learn to be mindful of professionalism while using social media in order to protect their privacy as well as the image of physicians.

ENGLISH ABSTRACT: Despite the current economic climate, the South African mining and engineering industry is experiencing a very promising future, with a large number of capital projects in the offing. It is inevitable that pilot plant development will form part of this future as a risk mitigation technique. This study found that, even though the terms ‘pilot plant’ and ‘project management maturity’ are familiar within the industry, no link between these two could be found in the literature. A number of maturity models exist; and one developed by PMSolutions was selected to perform an assessment of the current level of project management maturity within the South African mining and engineering industry pertaining to the development of pilot plants. The Delphi technique was used to determine the views of experts in the South African mining, mineral processing, petrochemical, nuclear, and mechanical sectors regarding this maturity. A significant difference was observed between the current level of maturity and the required level of maturity in all but one of the nine knowledge areas defined by the Project Management Institute. The two knowledge areas of project time and risk management showed significant differences between current and required maturity levels, and were identified as key areas for improvement.

Despite the evidence for early fetal experience exerting programming influences on later neurological development and health risk, very few prospective studies of human fetal behavior have been reported. In a prospective longitudinal study, fetal nervous system maturation was serially assessed by monitoring fetal heart rate (FHR) responses to vibroacoustic stimulation (VAS) in 191 maternal/fetal dyads. Responses were not detected at 26 weeks gestational age (GA). Sex-specific, age-characteristic changes in the FHR response to VAS were observed by 31 weeks' GA. Males showed larger responses and continued to exhibit maturational changes until 37 weeks' GA, females however, presented with a mature FHR startle response by 31 weeks' GA. The results indicate that there are different rates of maturation in the male and female fetuses that may have implications for sex-specific programming influences.

To investigate the relationship between cervical vertebrae maturation and mandibular second molar calcification stages. The study was designed as a retrospective, descriptive and crosssectional research project. Pre-treatment lateral cephalograms and panoramic radiographs of 99 males and 110 females in the age range of 7 to 18 years 7 months were evaluated with Demirjian Index (DI) and cervical vertebrae maturation indicators (CVMI) of Hassel and Farman. A null hypothesis was proposed that there is no relation between CVMI and DI. A highly significant association (Pearson's contingency coefficient 0.713 for males and 0.863 for females) was found between DI and CVMI. In males, the DI stage E corresponded to stage 2 of CVMI (pre-peak of pubertal growth spurt) and DI stages F and G corresponded to stages 3 and 4 of CVMI (peak of pubertal growth spurt). DI stage H was associated with stages 5 and 6 of CVMI (end of pubertal growth spurt). In females, the DI stages C, D corresponded to CVMI stages 1, 2; DI stages E, F with CVMI stages 3, 4; DI stages G, H with CVMI stages 5, 6. Mandibular second molar calcification stages can be used as indicators for assessment of skeletal maturity.

Palliative care professionals are exposed daily to high levels of suffering. This makes them particularly vulnerable to suffering from stress, which can lead to burnout and/or compassion fatigue. To analyse the professional trajectory of palliative care workers over time and the factors which influence this trajectory. A qualitative study was designed based on the Grounded Theory approach, using semi-structured individual interviews. Interviews were recorded audio-visually and transcribed verbatim for subsequent analysis using the procedure described by Miles and Huberman. This process was supported using ATLAS.ti 6 software. A total of 10 palliative care professionals from Extremadura (Spain) took part in the study. The analysis revealed a common trajectory followed by participants in their working lives: pre-palliative care/honeymoon/frustration/maturation. In addition, factors which influence this trajectory were identified. Details of the self-care strategies that these professionals have developed are described. The result of this process, which we have metaphorically termed 'metamorphosis', is the formation of a professional who can work satisfactorily within a palliative care context. During their professional activity, palliative care professionals go through a series of phases, depending on the relationship between the cost of caring and the satisfaction of caring, which can influence both the care provided to patients and families and their own personal circumstances. Being aware of this risk, and implementing self-care strategies, can protect professionals and enable them to conduct their work in an optimal manner. Reflecting on the experiences of these professionals could be useful for other health professionals. © The Author(s) 2015.

The Concept of Paleologic Thought According to Arieti

Directory of Open Access Journals (Sweden)

João Carlos Melo

2014-10-01

Full Text Available The Aristotelic Logic, which is characterized by four laws, is commonly accepted as being representative of normal though, when considered in its formal aspect. Arieti defends the existence of another logic, one that he has designated "Paleological", which was dominant in human beings in the beginning of their evolution, and that also occurs in certain characteristics of infantile thought, as well as in the primary process (manner in which the unconscious operates. The same author considers that this logic, whoch is quiescent, emerges in schizophrenic thought, dominating and overlapping the Aristotelian logic. In order to escape from anguish, the shizophrenic patient abandons Aristotelian norms of thought and adopts the Paleological form, because by interpreting reality, in light of Aristotelian logic, it's felt to be threatening and unbearable. Finally, Arieti explains that the principles of Paleological thought don't explain the phenomenon dynamically, merely formally. The study of psychodinamic mechanisms reveals what and why (content and motivation, while the study of formal mechanims reveal how, thoughts and feelings are processed.

Mature students' perspectives of studying radiography

International Nuclear Information System (INIS)

Williams, M.; Decker, S.

2009-01-01

The study set out to explore the experiences of all final year mature students on a diagnostic radiography course, in one United Kingdom University. The aims were to identify any difficulties they may have had and to make recommendations to improve mature students' learning experiences with the hope of lowering attrition rates in this group. A qualitative study involving one-to-one audio recorded interviews was utilised. Analysis of the transcripts of interviews suggested that the group believed that their maturity and previous experiences helped them in the clinical environment and put them in a good position, when asked, to counsel younger students. However for some of the mature students these experiential skills did not extend fully into seeking appropriate support for themselves. The mature students were found to be highly motivated but there was a conflict between balancing clinical and academic aspects of studying as well as balancing studying with home life. The group was found to be unprepared for the volume of academic work and its detrimental effect on family life as they sacrificed other aspects of their lives in order to complete the course. It is recommended that forewarning and forearming prospective mature students be considered by radiography education providers. Setting up and utilising an on-line forum providing a 24/7 peer support environment would aid in coping with academic, clinical or personal problems

Thought confidence as a determinant of persuasion: the self-validation hypothesis.

Science.gov (United States)

Petty, Richard E; Briñol, Pablo; Tormala, Zakary L

2002-05-01

Previous research in the domain of attitude change has described 2 primary dimensions of thinking that impact persuasion processes and outcomes: the extent (amount) of thinking and the direction (valence) of issue-relevant thought. The authors examined the possibility that another, more meta-cognitive aspect of thinking is also important-the degree of confidence people have in their own thoughts. Four studies test the notion that thought confidence affects the extent of persuasion. When positive thoughts dominate in response to a message, increasing confidence in those thoughts increases persuasion, but when negative thoughts dominate, increasing confidence decreases persuasion. In addition, using self-reported and manipulated thought confidence in separate studies, the authors provide evidence that the magnitude of the attitude-thought relationship depends on the confidence people have in their thoughts. Finally, the authors also show that these self-validation effects are most likely in situations that foster high amounts of information processing activity.

Chrétien, Maxime; Giroux, Isabelle; Goulet, Annie; Jacques, Christian; Bouchard, Stéphane

2017-12-01

Gamblers' thoughts have a fundamental influence on their gambling problem. Cognitive restructuring is the intervention of choice to correct those thoughts. However, certain difficulties are noted in the application of cognitive restructuring techniques and the comprehension of their guidelines. Furthermore, the increase of skill game players (e.g. poker) entering treatment creates a challenge for therapists, as these gamblers present with different thoughts than those of the gamblers usually encountered in treatment (e.g. chance-only games like electronic gambling machines). This systematic review aims to describe how cognitive restructuring is carried out with gamblers based on the evidence available in empirical studies that include cognitive interventions for gambling. Of the 2607 studies collected, 39 were retained. The results highlight exposure as the most frequently used technique to facilitate identification of gambling-related thoughts (imaginal=28.2%; in vivo=10.3%). More than half of the studies (69.2%) clearly reported therapeutic techniques aimed to correct gamblers' thoughts, of which 37% involved visual support to challenge those thoughts (e.g. ABC log). Of the 39 studies retained, 48.7% included skill game players (i.e., poker, blackjack, sports betting) in their sample. However, none of these studies mentioned whether cognitive restructuring had been adapted for these gamblers. Several terms referring to gamblers' thoughts were used interchangeably (e.g. erroneous, dysfunctional or inadequate thoughts), although each of these terms could refer to specific content. Clinical implications of the results are discussed with regard to the needs of therapists. This review also suggests recommendations for future research. Copyright © 2017 Elsevier Ltd.

Ball, Gina; Woodside, Donald; Tompson, Bryan; Hunter, W Stuart; Posluns, James

2011-05-01

The cervical vertebrae have been proposed as a method of determining biologic maturity. The purposes of this study were to establish a pattern of mandibular growth and to relate this pattern to the stages of cervical vertebral maturation. Cephalometric radiographs, taken annually from ages 9 to 18 years, were evaluated for 90 boys from the Burlington Growth Center, Toronto, Ontario, Canada. Mandibular lengths were measured from articulare to gnathion, and incremental growth was determined. Cervical vertebral maturation stages were assessed by using a 6-stage method. Advanced, average, and delayed maturation groups were established. The prepubertal mandibular growth minimum velocity occurred during cervical stages 1 through 4 (P = 0.7327). Peak mandibular growth velocity occurred most frequently during stage 4 in all 3 maturation groups, with a statistical difference in the average and delayed groups (P cervical stages 1 through 6 does not occur annually; time spent in each stage varies depending on the stage and the maturation group. Cervical vertebral maturation stages cannot accurately identify the mandibular prepubertal growth minimum and therefore cannot predict the onset of the peak in mandibular growth. The cervical vertebral maturation stages should be used with other methods of biologic maturity assessment when considering both dentofacial orthopedic treatment and orthognathic surgery.

Effects of Crocin Supplementation during In Vitro Maturation of Mouse Oocytes on Glutathione Synthesis and Cytoplasmic Maturation

Directory of Open Access Journals (Sweden)

Elham Mokhber Maleki

2016-05-01

Full Text Available Background: Crocin is an active ingredient of saffron (Crocus sativus L. and its antioxidant properties have been previously investigated. This carotenoid scavenges free radicals and stimulates glutathione (GSH synthesis; consequently, it may protect cells against oxidative stress. The aim of this research is to protect oocytes from oxidative stress by the addition of a natural source antioxidant. Materials and Methods: In the present in vitro experimental study, we collected cumulus oocyte complexes (COCs from mouse ovaries of euthanized, 6-8 week-old female Naval Medical Research Institute (NMRI mice. Oocytes were subjected to in vitro maturation (IVM in the presence of either crocin (5 or 10 μg/ml, 5 mM buthionine-[S-R]- sulfoximine (BSO, or the combination of crocin plus BSO. Oocytes that matured in vitro in a medium without crocin or BSO supplements were considered as controls. Following 16-18 hours of IVM, matured oocytes (n=631 were fertilized by capacitated sperm from NMRI male mice, and cultured in vitro for up to 96 hours to assess preimplantation embryonic development. The levels of GSH in metaphase II (MII oocytes after IVM (n=240 were also assessed by the 5, 5-dithio-bis (2-nitrobenzoic acid (DTNB-GSH reductase recycling assay. Results: Supplementation of IVM media with 10 μg/ml crocin significantly (P<0.05 increased nuclear maturation, preimplantation development and GSH concentrations compared with the control group. Maturation of oocytes in IVM medium supplemented with BSO alone or the combination of 5 μg/ml crocin and BSO drastically decreased GSH concentrations and subsequently resulted in low rates of maturation, fertilization and blastocyst development. However, the combination of 10 μg/ml crocin with 5 mM BSO increased the level of nuclear maturation which was comparable to the control group. Conclusion: Supplementation of IVM media with crocin can improve nuclear maturation rates and subsequent developmental potential

Preaching What We Practice: Teaching Ethical Decision-Making to Computer Security Professionals

Science.gov (United States)

Fleischmann, Kenneth R.

The biggest challenge facing computer security researchers and professionals is not learning how to make ethical decisions; rather it is learning how to recognize ethical decisions. All too often, technology development suffers from what Langdon Winner terms technological somnambulism - we sleepwalk through our technology design, following past precedents without a second thought, and fail to consider the perspectives of other stakeholders [1]. Computer security research and practice involves a number of opportunities for ethical decisions. For example, decisions about whether or not to automatically provide security updates involve tradeoffs related to caring versus user autonomy. Decisions about online voting include tradeoffs between convenience and security. Finally, decisions about routinely screening e-mails for spam involve tradeoffs of efficiency and privacy. It is critical that these and other decisions facing computer security researchers and professionals are confronted head on as value-laden design decisions, and that computer security researchers and professionals consider the perspectives of various stakeholders in making these decisions.

Professionalism: A Core Competency, but What Does it Mean? A Survey of Surgery Residents.

Science.gov (United States)

Dilday, Joshua C; Miller, Elizabeth A; Schmitt, Kyle; Davis, Brian; Davis, Kurt G

2017-10-27

Professionalism is 1 of the 6 core competencies of the Accreditation Council of Graduate Medical Education. Despite its obvious importance, it is poorly defined in the literature and an understanding of its meaning has not been evaluated on surgical trainees. The American College of Surgeons (ACS) has previously published tenets of surgical professionalism. However, surgery residents may not share similar views on professionalism as those of the ACS. Surgical residents of all levels at 2 surgery residencies located in the same city were interviewed regarding their personal definitions, thoughts, and experiences regarding professionalism during their training. They were then queried regarding 20 points of professionalism as outlined by the ACS tenets of professionalism. The study utilized the surgery residencies at William Beaumont Army Medical Center and Texas Tech University Health Science Center in El Paso, Texas. All general surgery residents at each program were invited to participate in the study. Eighteen residents volunteered to take the survey and be interviewed. The definitions of professionalism centered on clinical competence. Surgery residents conveyed experiences with both professional and unprofessional behavior. Seven of the 20 ACS tenets of professionalism were unanimously agreed upon. There were key differences between resident definitions and those as outlined by the ACS. The least agreed upon ACS tenets of professionalism include professionalism education, public education, and public health. Surgical trainees express personal experiences in both professional and unprofessional behavior. Their definitions of professionalism are not as expansive as those of the ACS and seem to focus on patient and colleague interaction. Due to the lack of congruency, a tailored curriculum for professionalism based upon ACS tenets appears warranted. Published by Elsevier Inc.

In total 531 articles were initially found matching the search criteria, which was filtered to 39 articles by applying specific exclusion criteria. Contribution:: The article highlights the trends in agile maturity model research, specifically bringing to light the lack of research providing validation of such models. Findings: Two major themes emerge, being the coexistence of agile and CMMI and the development of agile principle based maturity models. The research trend indicates an increase in agile maturity model articles, particularly in the latter half of the last decade, with concentrations of research coinciding with version updates of CMMI. While there is general consensus around higher CMMI maturity levels being incompatible with true agility, there is evidence of the two coexisting when agile is introduced into already highly matured environments. Future Research:\tFuture research direction for this topic should include how to attain higher levels of CMMI maturity using only agile methods, how governance is addressed in agile environments, and whether existing agile maturity models relate to improved project success.

Customer-Provider Strategic Alignment: A Maturity Model

Science.gov (United States)

Luftman, Jerry; Brown, Carol V.; Balaji, S.

This chapter presents a new model for assessing the maturity of a ­customer-provider relationship from a collaborative service delivery perspective: the Customer-Provider Strategic Alignment Maturity (CPSAM) Model. This model builds on recent research for effectively managing the customer-provider relationship in IT service outsourcing contexts and a validated model for assessing alignment across internal IT service units and their business customers within the same organization. After reviewing relevant literature by service science and information systems researchers, the six overarching components of the maturity model are presented: value measurements, governance, partnership, communications, human resources and skills, and scope and architecture. A key assumption of the model is that all of the components need be addressed to assess and improve customer-provider alignment. Examples of specific metrics for measuring the maturity level of each component over the five levels of maturity are also presented.

Despite the evidence for early fetal experience exerting programming influences on later neurological development and health risk, very few prospective studies of human fetal behavior have been reported. In a prospective longitudinal study, fetal nervous system maturation was serially assessed by monitoring fetal heart rate (FHR) responses to vibroacoustic stimulation (VAS) in 191 maternal/fetal dyads. Responses were not detected at 26 weeks gestational age (GA). Sex-specific, age-characteristic changes in the FHR response to VAS were observed by 31 weeks’ GA. Males showed larger responses and continued to exhibit maturational changes until 37 weeks’ GA, females however, presented with a mature FHR startle response by 31 weeks’ GA. The results indicate that there are different rates of maturation in the male and female fetus that may have implications for sex-specific programming influences. PMID:19726143

Full Text Available The practical and conceptual challenges faced by the analysis of trace elements present in natural waters are not merely, as is often thought, an endless race towards lower detection limits or to the development of techniques allowing the determination of any possible chemical species formed by all chemical elements. Rather, as discussed in this paper, they include the development of (i robust, cheap, and reliable methods that could also be used by laypeople (the experience gained in the development of field kits for As is discussed as an example from which similar developments for other elements may be drawn; (ii more environmentally-friendly methods (the current guiding criteria probably being too simplistic; and (iii methods making it possible to follow diel concentration changes and sharp concentration variations caused by the probable increase of heavy rainfall events. This paper also claims that neither the measurement of total concentrations (reliable methods are lacking for many elements of the periodic table of trace elements, as illustrated through the cases of Bi, Te, and Sb, nor chemical speciation analysis, are as mature as often thought. In particular, chemical speciation studies demand the development of a better, comprehensive conceptual framework. A trial is carried out to lay the basis of such a framework.

2011-01-01

Skeletal age had been assessed by comparison between maturation of hand-wrist with stages of cervical vertebrae or canine calcification stages in past and this had been closely related to craniofacial growth. The importance of pubertal growth spurt in various types of orthodontic therapies is already established. Hence, this study was aimed to evaluate the relationship of skeletal maturity by hand-wrist with cervical vertebral maturation indicators and canine calcification stages. The study consisted of randomly selected 90 children from Lucknow population with 45 males (age range 10-13 years) and 45 females (age range 9-12 years). Lateral Cephalogram, hand-wrist x-ray, and periapical x-rays of maxillary and mandibular right canines were taken. Mean, standard deviation was calculated of different groups. Correlation was made among cervical vertebral maturation, hand wrist maturation, and canine calcification stages at various age groups. There was strong correlation between skeletal maturation indicator and cervical vertebral maturation indicator for both male (0.849) and female (0.932), whereas correlation between skeletal maturation indicator and canine calcification was good for both male and female (0.635, 0.891). It was concluded that cervical vertebral maturation indicator and canine calcification stages can also be used for assessing skeletal maturity.

The seeds of a sugar maple tree (Acer saccharum Marsh.) do not mature at the same time every year. And different trees mature their seeds at different times. So time of year is not a reliable measure of when seeds are ripe. Better criteria are needed. In recent studies we have found that moisture content and color are the best criteria for judging when sugar maple...

Williams, Randi

This study was designed to explore elementary STEM professional development viewed from the presenters' and participants' perspectives. Numerous committees and educational organizations recommend investing in STEM professional development at the local, state, and national level. This investment must begin with research that inquires how STEM professional development is structured and what is needed for teacher and student success. Since there is a recent STEM education push in schools, elementary teachers need effective professional development in order to gain the necessary content, skills, confidence, and pedagogy required for those changing demands. This qualitative study embraced. Yin's case study methodology by observing short-duration STEM professional development for elementary teachers within a large metropolitan school system and an educational professional development agency. The study discussed the analysis and findings in the context of Bandura's sources of efficacy and Desimone's critical features of professional development. Data were gathered form professional development observations, presenter interviews, and participant interviews. The research questions for this study included: (a) based on Desimone's (2009) framework for professional development, what does content focused, active learning, coherence, duration, and collective participation look like in initial STEM professional development for elementary teachers? (b) are Bandura's (1997) four sources of self- efficacy: mastery experiences, vicarious experiences, social persuasion, and affective states evidenced within the short duration professional development? and (c) how do these two frameworks align between presenter and participant thoughts and actions? This study uncovered additional sources of efficacy are present in short-duration STEM professional development. These found sources include coherence, content, and active learning delivered in a definitive order. The findings of this study

Full Text Available For any business to operate effectively, a governance framework that operates at the relevant maturity level is required. An organisational governance maturity framework is a tool that leadership can use to determine governance maturity. This study aims to determine whether the organisational governance maturity framework (developed by Wilkinson can be applied to the selected retail industry organisation to assess the maturity of the organisation’s governance, limited to the ‘leadership’ attribute. Firstly, a high-level literature review on ethical leadership, ethical decision-making, ethical foundation and culture (‘tone at the top’, and organisational governance and maturity was conducted. Secondly, a Johannesburg Stock Exchange (JSE listed South African-based company was selected for the empirical part of the study using a single case study research design. The empirical results confirmed that the organisational governance maturity framework can be used to determine the maturity level of organisational governance for the selected attribute of ‘leadership’

Professionalism is a core competency in the medical profession worldwide. Numerous studies investigate how this competency is taught and learned. However, there are few reports on the students' views and experiences with professionalism especially in the Arab world. Our aim was to explore the experiences and views of Kuwait final-year medical students on professionalism. This was a questionnaire study of final-year medical students at Kuwait University (n = 95). Open- and close-ended questions were used to determine the students' experiences and views on: definition, teaching, learning, and assessment of professionalism. Eighty-five of the students completed the questionnaire (89.5%). A total of 252 attributes defining professionalism were listed by our respondents. The majority (98.0%) of these attributes were categorized under the CanMEDS theme describing professionalism as commitment to patients, profession, and society through ethical practice. The most helpful methods in learning about professionalism for the students were contact with positive role models, patients and families, and with their own families, relatives and peers. The students' rating of the quality and quantity of teaching professionalism in the institution was quite variable. Despite this, 68.2% of the students felt very or somewhat comfortable explaining the meaning of medical professionalism to junior medical students. Almost half of the students felt that their education had always or sometimes helped them deal with professionally-challenging situations. Majority (77.6%) of the students thought that their academic assessments should include assessment of professionalism and should be used as a selection criterion in their future academic careers (62.3%). Most of the students discussed and sought advice regarding professionally-challenging situations from their fellow medical students and colleagues. Seventy-five (88.2%) students did not know which organizational body in the institution

Insights into the functionality of the putative residues involved in enterocin AS-48 maturation.

Science.gov (United States)

Cebrián, Rubén; Maqueda, Mercedes; Neira, José Luis; Valdivia, Eva; Martínez-Bueno, Manuel; Montalbán-López, Manuel

2010-11-01

AS-48 is a 70-residue, α-helical, cationic bacteriocin produced by Enterococcus faecalis and is very singular in its circular structure and its broad antibacterial spectrum. The AS-48 preprotein consists of an N-terminal signal peptide (SP) (35 residues) followed by a proprotein moiety that undergoes posttranslational modifications to yield the mature and active circular protein. For the study of the specificity of the region of AS-48 that is responsible for maturation, three single mutants have been generated by site-directed mutagenesis in the as-48A structural gene. The substitutions were made just in the residues that are thought to constitute a recognition site for the SP cleavage enzyme (His-1, Met1) and in those involved in circularization (Met1, Trp70). Each derivative was expressed in the enterococcal JH2-2 strain containing the necessary native biosynthetic machinery for enterocin production. The importance of these derivatives in AS-48 processing has been evaluated on the basis of the production and structural characterization of the corresponding derivatives. Notably, only two of them (Trp70Ala and Met1Ala derivatives) could be purified in different forms and amounts and are characterized for their bactericidal activity and secondary structure. We could not detect any production of AS-48 in JH2-2(pAM401-81(His-1Ile)) by using the conventional chromatographic techniques, despite the high efficiency of the culture conditions applied to produce this enterocin. Our results underline the different important roles of the mutated residues in (i) the elimination of the SP, (ii) the production levels and antibacterial activity of the mature proteins, and (iii) protein circularization. Moreover, our findings suggest that His-1 is critically involved in cleavage site recognition, its substitution being responsible for the blockage of processing, thereby hampering the production of the specific protein in the cellular culture supernatant.

Plk1 relieves centriole block to reduplication by promoting daughter centriole maturation

Science.gov (United States)

Shukla, Anil; Kong, Dong; Sharma, Meena; Magidson, Valentin; Loncarek, Jadranka

2015-01-01

Centrosome overduplication promotes mitotic abnormalities, invasion and tumorigenesis. Cells regulate the number of centrosomes by limiting centriole duplication to once per cell cycle. The orthogonal orientation between a mother and a daughter centriole, established at the time of centriole duplication, is thought to block further duplication of the mother centriole. Loss of orthogonal orientation (disengagement) between two centrioles during anaphase is considered a licensing event for the next round of centriole duplication. Disengagement requires the activity of Polo-like kinase 1 (Plk1), but how Plk1 drives this process is not clear. Here we employ correlative live/electron microscopy and demonstrate that Plk1 induces maturation and distancing of the daughter centriole, allowing reduplication of the mother centriole even if the original daughter centriole is still orthogonal to it. We find that mother centrioles can undergo reduplication when original daughter centrioles are only ∼80 nm apart, which is the distance centrioles normally reach during prophase. PMID:26293378

Language as an instrument of thought

Directory of Open Access Journals (Sweden)

Eran Asoulin

2016-11-01

Full Text Available I show that there are good arguments and evidence to boot that support the language as an instrument of thought hypothesis. The underlying mechanisms of language, comprising of expressions structured hierarchically and recursively, provide a perspective (in the form of a conceptual structure on the world, for it is only via language that certain perspectives are available to us and to our thought processes. These mechanisms provide us with a uniquely human way of thinking and talking about the world that is different to the sort of thinking we share with other animals. If the primary function of language were communication then one would expect that the underlying mechanisms of language will be structured in a way that favours successful communication. I show that not only is this not the case, but that the underlying mechanisms of language are in fact structured in a way to maximise computational efficiency, even if it means causing communicative problems. Moreover, I discuss evidence from comparative, neuropathological, developmental, and neuroscientific evidence that supports the claim that language is an instrument of thought.

2016-04-01

This article introduces the Game Maturity Model for the healthcare industry as an extension to the general Game Maturity Model and describes the usage by two case studies of applied health games. The Game Maturity Model for healthcare provides a practical and value-adding method to assess existing games and to determine strategic considerations for application of applied health games. Our forecast is that within 5 years the use and development of applied games will have a role in our daily lives and the way we organize health care that will be similar to the role social media has today.

The appraisal of intrusive thoughts in relation to obsessional-compulsive symptoms.

Science.gov (United States)

Barrera, Terri L; Norton, Peter J

2011-01-01

Research has shown that although intrusive thoughts occur universally, the majority of individuals do not view intrusive thoughts as being problematic (Freeston, Ladouceur, Thibodeau, & Gagnon, 1991; Rachman & de Silva, 1978; Salkovskis & Harrison, 1984). Thus, it is not the presence of intrusive thoughts that leads to obsessional problems but rather some other factor that plays a role in the development of abnormal obsessions. According to the cognitive model of obsessive-compulsive disorder (OCD) put forth by Salkovskis (1985), the crucial factor that differentiates between individuals with OCD and those without is the individual's appraisal of the naturally occurring intrusive thoughts. This study aimed to test Salkovskis's model by examining the role of cognitive biases (responsibility, thought-action fusion, and thought control) as well as distress in the relationship between intrusive thoughts and obsessive-compulsive symptoms in an undergraduate sample of 326 students. An existing measure of intrusive thoughts (the Revised Obsessional Intrusions Inventory) was modified for this study to include a scale of distress associated with each intrusive thought in addition to the current frequency scale. When the Yale-Brown Obsessive-Compulsive Scale was used as the measure of OCD symptoms, a significant interaction effect of frequency and distress of intrusive thoughts resulted. Additionally, a significant three-way interaction of Frequency × Distress × Responsibility was found when the Obsessive Compulsive Inventory-Revised was used as the measure of OCD symptoms. These results indicate that the appraisal of intrusive thoughts is important in predicting OCD symptoms, thus providing support for Salkovskis's model of OCD.

Teaching thoughtful practice: narrative pedagogy in addictions education.

Vandermause, Roxanne K; Townsend, Ryan P

2010-07-01

Preparing practitioners for this rapidly changing and demanding health care environment is challenging. A surge in knowledge development and scientific advancement has placed a priority on technical skill and a focus on content driven educational processes that prepare students for evidence-based practice. However, the most difficult health care scenarios require thinking-in-action and thoughtfulness as well as didactic knowledge. It is our contention that interpretive educational methods, like narrative pedagogy, will promote judgment-based practice that includes use of evidence and delivery of thoughtful care. In this article, we describe and interpret a narrative approach to addictions content and teaching thoughtful practice. We present our pedagogical process, including observations and field notes, to show how interpretive pedagogies can be introduced into nursing curricula. By presenting this process, the reader is invited to consider interpretive methods as a way to inspire and habituate thoughtful practice and judgment-based care. Copyright 2009 Elsevier Ltd.

It is difficult for humans to apply small amounts of force precisely during motor control. However, experts who have undergone extended training are thought to be able to control low-velocity movement with precision. We investigated the resolution of motor control in golf putting. A total of 10 professional and 10 high-level amateur golfers participated. Putting distances were 0.6-3.3 m, in increments of 0.3 m. We measured the impact velocity and the club-face angle at impact, and the acceleration profile of the downswing. The professionals showed significantly smaller coefficients of variation with respect to impact velocity and smaller root mean square errors in relation to acceleration profiles than did the amateurs. To examine the resolution of motor control for impact velocity, we investigated intra-participant differences in the impact velocity of the club head at two adjacent distances. We found that professionals had higher velocity precision when putting small distance intervals than did amateurs. That is, professionals had higher resolution of low-velocity control than did high-level amateurs. Our results suggest that outstanding performance at a task involves the ability to recognise small distinctions and to produce appropriate movements.

Color back projection for fruit maturity evaluation

Science.gov (United States)

Zhang, Dong; Lee, Dah-Jye; Desai, Alok

2013-12-01

In general, fruits and vegetables such as tomatoes and dates are harvested before they fully ripen. After harvesting, they continue to ripen and their color changes. Color is a good indicator of fruit maturity. For example, tomatoes change color from dark green to light green and then pink, light red, and dark red. Assessing tomato maturity helps maximize its shelf life. Color is used to determine the length of time the tomatoes can be transported. Medjool dates change color from green to yellow, and the orange, light red and dark red. Assessing date maturity helps determine the length of drying process to help ripen the dates. Color evaluation is an important step in the processing and inventory control of fruits and vegetables that directly affects profitability. This paper presents an efficient color back projection and image processing technique that is designed specifically for real-time maturity evaluation of fruits. This color processing method requires very simple training procedure to obtain the frequencies of colors that appear in each maturity stage. This color statistics is used to back project colors to predefined color indexes. Fruit maturity is then evaluated by analyzing the reprojected color indexes. This method has been implemented and used for commercial production.

Professional tools and a personal touch - experiences of physical therapy of persons with migraine.

Science.gov (United States)

Rutberg, Stina; Kostenius, Catrine; Öhrling, Kerstin

2013-09-01

The aim was to explore the lived experience of physical therapy of persons with migraine. Data were collected by conducting narrative interviews with 11 persons with migraine. Inspired by van Manen, a hermeneutic phenomenological method was used to analyse the experiences of physical therapy which these persons had. Physical therapy for persons with migraine meant making an effort in terms of time and energy to improve their health by meeting a person who was utilising his or her knowledge and skill to help. Being respected and treated as an individual and having confidence in the physical therapist were highlighted aspects. The analysis revealed a main theme, "meeting a physical therapist with professional tools and a personal touch". The main theme included four sub-themes, "investing time and energy to feel better", "relying on the competence of the physical therapist", "wanting to be treated and to become involved as an individual" and "being respected in a trustful relationship". The therapeutic relationship with the physical therapist is important and the findings of this study can increase awareness about relational aspects of physical therapy and encourage thoughtfulness among physical therapists and other healthcare professionals interacting with persons with migraine. Physical therapists use both professional tools and a personal touch in their interaction with persons with migraine and this article can increase physical therapists' awareness and encourage thoughtfulness in their professional practice. Being respected and treated as an individual and having confidence in the physical therapist are important aspects of the therapeutic relationship and indicate a need for patient-centred care. By making the effort of spending the time and energy required, physical therapy could be a complement or an alternative to medication to ease the consequences of migraine.

2013-12-01

Full Text Available This article deals with service quality and the methods for its measurement and improvements to reach the so called service excellence. Besides older methods such as SERVQUAL and SERPERF, there are also shortly described capability maturity models based on which the own methodology is developed and used for process maturity assessment in organizations providing technical services. This method is equally described and accompanied by examples on pictures. The verification of method functionality is explored on finding a correlation between service employee satisfaction and average process maturity in a service organization. The results seem to be quite promising and open an arena for further studies.

2002-12-01

Mature weight and rate of maturing were estimated in 177 Angus, Brahman, and reciprocal-cross cows grazing bermudagrass or endophyte-infected tall fescue over a 4-yr period to evaluate genotype x environment interactions. Data were collected every 28 d until cows were approximately 18 mo of age and then at prebreeding, postcalving, and weaning of calf. All cows with weight data to at least 42 mo of age were included in the analysis. Mature weight and rate of maturing were estimated using the three-parameter growth curve model described by Brody (1945). Data were pooled over year and analyzed by the general linear model procedure of SAS. Included in the models for mature weight and rate of maturing were the independent variables of genotype, environment, and genotype x environment interaction. There was a genotype x environment interaction (P < 0.01) for mature body weight (BW) but not for rate of maturing. Angus cows grazing fescue pastures had greater (P < 0.01) mean mature BW than Angus x Brahman cows grazing bermudagrass (611 +/- 17 vs 546 +/- 16 kg). Angus x Brahman cows grazing bermudagrass had lower (P < 0.05) mean mature BW than Brahman x Angus cows grazing bermudagrass or endophyte-infected fescue and Brahman cows grazing bermudagrass (546 +/- 16 vs 624 +/- 19, 614 +/- 22 and 598 +/- 20 kg, respectively). Brahman cows grazing endophyte-infected fescue had smaller (P < 0.05) mean mature BW than all genotype x forage combinations except for Angus x Brahman cows grazing bermudagrass. Angus cows had a smaller (P < 0.05) mean rate of maturing than Angus x Brahman and Brahman x Angus cows (0.039 +/- 0.002 vs 0.054 +/- 0.002 and 0.049 +/- 0.002%/mo, respectively), respectively, and Angus x Brahman cows had a larger (P < 0.05) mean rate of maturing than Brahman x Angus and Brahman cows (0.054 +/- 0.002 vs 0.049 +/- 0.002 and 0.041 +/- 0.002 %/mo, respectively). There was a direct breed x forage interaction (P < 0.05) for mature BW. These data suggest that the

Induction and inhibition of oocyte maturation by EDCs in zebrafish

Directory of Open Access Journals (Sweden)

Tokumoto Mika

2005-12-01

Full Text Available Abstract Background Oocyte maturation in lower vertebrates is triggered by maturation-inducing hormone (MIH, which acts on unidentified receptors on the oocyte surface and induces the activation of maturation-promoting factor (MPF in the oocyte cytoplasm. We previously described the induction of oocyte maturation in fish by an endocrine-disrupting chemical (EDC, diethylstilbestrol (DES, a nonsteroidal estrogen. Methods In this study, stimulatory and inhibitory effects of EDCs and natural steroids on oocyte maturation were examined in zebrafish. For effective agents, some details about the mechanism in induction or inhibition of maturation were examined. Possible groups of DES interacting with the MIH receptor are discussed based on relative potency of steroids to induce maturation. Results Among agents tested, tamoxifen (TAM and its metabolite 4-hydroxytamoxifen (4-OHT showed stimulatory activity similar to DES. The time courses of the change in germinal vesicle breakdown and an intracellular molecular event (the synthesis of cyclin B induced by TAM were indistinguishable from those induced by MIH. In contrast, pentachlorophenol (PCP had a potent inhibitory effect on MIH-induced oocyte maturation. PCP inhibited not only MIH-induced maturation but also DES- and TAM-induced maturation. Methoxychlor also inhibited maturation when oocytes were pre-treated with this agent. Conclusion These results suggest that EDCs act as agonists or antagonists in the induction of oocyte maturation in fish.

The secondary phloem of 3 species of the Taxodiaceae and 13 species of woody dicotyledons was examined for the occurrence of nuclei in mature sieve elements. Nuclei were found in all mature sieve cells of Metasequoia glyptostroboides, Sequoia sempervirens and Taxodium distichum, and in some mature sieve-tube members in 12 of the 13 species of woody dicotyledons. Except for nuclei of sieve cells undergoing cessation of function, the nuclei in mature sieve cells of M. glyptostroboides, S. sempervirens and T. distichum were normal in appearance. The occurrence and morphology of nuclei in mature sieve-tube members of the woody dicotyledons were quite variable. Only 3 species, Robinia pseudoacacia, Ulmus americana and Vitis riparia, contained some mature sieve elements with apparently normal nuclei.

A model-independent view of the mature organization

Energy Technology Data Exchange (ETDEWEB)

Hanna, M.; Langston, D.

1996-12-31

Over the last 10 years, industry has been dealing with the issues of process and organizational maturity. This focus on process is driven by the success that manufacturing organizations have had implementing the management principles of W. Edwards Deming and Joseph M. Juran. The organizational-maturity focus is driven by organizations striving to be ISO 9000 compliant or to achieve a specific level on one of the maturity models. Unfortunately, each of the models takes a specific view into what is a very broad arena. That is to say, each model addresses only a specific subset of the characteristics of maturity. This paper attempts to extend beyond these specific views to answer the general question, What is a mature organization and its relationship to Quantitative management and statistical process control?

Full Text Available The paper aims to present results of the study on business process maturity in relation to organisational performance. A two-phase methodology, based on literature review and survey was used. The literature is a source of knowledge about business process maturity and organisational performance, whereas the research on process maturity vs organisational performance in Polish Enterprises provides findings based on 84 surveyed companies. The main areas of the research covered: identification and analysis of maturity related variables and identification of organisational performance perspectives and its relation to process maturity. The study shows that there is a significant positive relation between process maturity and organisational performance. Although there are research on such relation available, they are scarce and have some significant limitations in terms of research sample or the scope of maturity or organisational performance covered. This publication is part of a project funded by the National Science Centre awarded by decision number DEC-2011/01/D/HS4/04070.

Maturation arrest of human oocytes at germinal vesicle stage

2010-01-01

Full Text Available Maturation arrest of human oocytes may occur at various stages of the cell cycle. A total failure of human oocytes to complete meiosis is rarely observed during assisted conception cycles. We describe here a case of infertile couples for whom all oocytes repeatedly failed to mature at germinal vesicle (GV stage during in vitro fertilization/Intra cytoplasmic sperm injection (IVF/ICSI. The patient underwent controlled ovarian stimulation followed by oocyte retrieval and IVF/ICSI. The oocytes were stripped off cumulus cells prior to the ICSI procedure and their maturity status was defined. The oocyte maturation was repeatedly arrested at the GV. Oocyte maturation arrest may be the cause of infertility in this couple. The recognition of oocyte maturation arrest as a specific medical condition may contribute to the characterization of the currently known as "oocyte factor." The cellular and genetic mechanisms causing oocyte maturation arrest should be the subject for further investigation.

Full Text Available One of the most important criteria in breeding process of perennial grasses is maturity. Cultivars with different maturity play a very important role in utilization of perennial grasses, by providing the ability to create a mixture of different aspects utilization and time. The first grass species in Serbia whose breeding program involved this criterion was cocksfoot (Dactylis glomerata L.. In general cocksfoot is early to medium-early in maturity in comparison with other grasses and legumes, and that is mayor problem since in the optimum phase for cutting, cocksfoot is often earlier then other species in mixtures. As a result of this work, in the previous period, two cultivars of different maturity were released, Kruševačka 24 (K-24 and Kruševačka 25 (K-25. K-24 is medium and K-25 is late in maturity. New material is adapted to local agro-ecological conditions and productive in the same time. In breeding process of both cultivars initial material originated from autochthonous populations collected in eastern and central Serbia. Material from the wild flora is selected based on medium and late maturity which is already adapted and has good productivity. We applied the standard method of phenotypic recurrent selection with the creation of synthetic varieties by polycross.

The variation of skeletal maturity about chronological age is a sensitive indicator of population health. Age appropriate or advanced skeletal maturity is a reflection of adequate environmental and social conditions, whereas delayed maturation suggests inadequate conditions for optimal development. There remains a paucity of data, however, to indicate which specific biological and environmental factors are associated with advancement or delay in skeletal maturity. The present study utilises longitudinal data from the South African Birth to Twenty (Bt20) study to indentify predictors of relative skeletal maturity (RSM) in early adolescence. A total of 244 black South African children (n=131 male) were included in this analysis. Skeletal maturity at age 9/10 years was assessed using the Tanner and Whitehouse III RUS technique. Longitudinal data on growth, socio-economic position and pubertal development were entered into sex-specific multivariable general linear regression models with relative skeletal maturity (skeletal age-chronological age) as the outcome. At 9/10 years of age males showed an average of 0.66 years delay in skeletal maturation relative to chronological age. Females showed an average of 1.00 year delay relative to chronological age.

The perspectives of nursing professionals might differ from those of older adults when it comes to care for older people. This cross-sectional study compares the views of older adults with the views of nursing professionals on the quality of care after a nationwide improvement program for care for older people was implemented (2008-2016) in the Netherlands. Questionnaire data were used from 385 nursing professionals (response rate 51%) that were part of the Nursing Staff Panel, a nationwide representative group of nursing staff, and working in home care, hospitals or general practices. Additionally, questionnaire data were used from 73 older adults (response rate 81%) who were involved in regional networks to discuss project proposals and to represent the voice of older adults in the nationwide improvement program. Participants were asked to evaluate care for older people with regard to collaboration between healthcare organizations and with regard to the tailored service, accessibility, and quality of care within their organizations and in the region in which they lived. A majority of older adults (54%) and nursing professionals (61%) felt that collaboration with others had improved over the last few years. Approximately one third of the older adults stated that care for older people was tailored to fit individual needs and was accessible most of the time or always, as opposed to approximately two thirds of the professionals. Moreover, 17% older adults thought that the quality of care was good, compared with 54% of the nursing professionals. 77% of the nursing professionals and 94% of the older adults thought that improvements were still needed in care for older people, for example better integration of the different aspects of care and a more patient-centered approach. Older adults who were involved in networks of the improvement program generally gave a less positive evaluation of aspects of care for older people and its development than nursing professionals

Food thought suppression, or purposely attempting to avoid thoughts of food, is related to a number of unwanted eating- and weight-related consequences, particularly in dieting and obese individuals. Little is known about the possible significance of food thought suppression in clinical samples, particularly obese patients who binge eat. This study examined food thought suppression in 150 obese patients seeking treatment for binge eating disorder (BED). Food thought suppression was not associated with binge eating frequency or body mass index but was significantly associated with higher current levels of eating disorder psychopathology and variables pertaining to obesity, dieting, and binge eating.

Yielder, Jill; Moir, Fiona

2016-01-01

The introduction of a new domain of learning for Personal and Professional Skills in the medical program at the University of Auckland in New Zealand has involved the compilation of a portfolio for assessment. This departure from the traditional assessment methods predominantly used in the past has been challenging to design, introduce, and maintain as a relevant and authentic assessment method. We present the portfolio format along with the process for its introduction and appraise the challenges, strengths, and limitations of the approach within the context of the current literature. We then outline a cyclical model of evaluation used to monitor and fine-tune the portfolio tasks and implementation process, in response to student and assessor feedback. The portfolios have illustrated the level of insight, maturity, and synthesis of personal and professional qualities that students are capable of achieving. The Auckland medical program strives to foster these qualities in its students, and the portfolio provides an opportunity for students to demonstrate their reflective abilities. Moreover, the creation of a Personal and Professional Skills domain with the portfolio as its key assessment emphasizes the importance of reflective practice and personal and professional development and gives a clear message that these are fundamental longitudinal elements of the program.

Casey, Christine; Gill, Daljit S; Jones, Steven P

2013-12-01

The aims of this study were to (1) investigate if there is a difference in skeletal maturation between tooth agenesis and control patients and (2) whether skeletal maturation is affected by the severity of tooth agenesis. The cervical vertebral maturation (CVM) index can be used to assess skeletal maturation. A retrospective cross-sectional study. Eastman Dental Hospital, London, UK. A total of 360 cephalograms of patients aged 9-17 years (164 males and 196 females) allocated to four subgroups (mild, moderate and severe tooth agenesis patients, and controls) were assessed retrospectively. There were 90 patients in each of the four subgroups. The skeletal maturation of each subject was assessed both quantitatively and qualitatively using the CVM index. All patients in the study were either currently receiving treatment or had been discharged from the hospital. There was no statistically significant relationship between skeletal maturation and the presence of tooth agenesis. Furthermore, there was no statistically significant relationship between the skeletal maturity of patients and different severities of tooth agenesis. The data obtained from this group of patients and using this measurement tool alone does not supply sufficient reason to reject the null hypothesis. However, it suggests that it is possible that no difference exists between the groups.

The construction of professional identity by physiotherapists: a qualitative study.

Science.gov (United States)

Hammond, Ralph; Cross, Vinette; Moore, Ann

2016-03-01

The U.K. Frances Report and increasing societal expectations of healthcare have challenged physiotherapists to reconsider professionalism. Physiotherapy has viewed identity as a fixed entity emphasising coherence, continuity and distinctiveness. Socialisation has required the acquisition of a professional identity as one necessary 'asset' for novices. Yet how do physiotherapists come to be the physiotherapists they are? Qualitative study using Collective Memory Work. Eight physiotherapists in South West England met for two hours, once a fortnight, for six months. Seventeen hours of group discussions were recorded and transcribed. Data were managed via the creation of crafted dialogues and analysed using narrative analysis. Participants shared ethical dilemmas: successes and unresolved anxiety about the limits of personal actions in social situations. These included matters of authenticity, role strain, morality, diversity. Participants made claims about their identity; claims made to support an attitude, belief, motivation or value. Professional identity in physiotherapy is more complex than traditionally thought; fluid across time and place, co-constructed within changing communities of practice. An ongoing and dynamic process, physiotherapists make sense and (re)interpret their professional self-concept based on evolving attributes, beliefs, values, and motives. Participants co-constructed the meaning of being a physiotherapist within intra-professional and inter-professional communities of practice. Patients informed this, and it was mediated by workplace and institutional discourses, boundaries and hierarchies, through an unfolding career and the contingencies of a life story. More empirical data are required to understand how physiotherapists negotiate the dilemmas they face and enact the values the profession espouses. Copyright © 2015 Chartered Society of Physiotherapy.

2011-10-01

The present study examined whether beliefs about the importance of thoughts (i.e., thought--action fusion; TAF) are related to the target subject of the negative thought. One hundred and seven undergraduate students were randomly assigned to imagine either a beloved relative or a stranger being diagnosed with cancer and provided in vivo ratings of anxiety, likelihood, moral wrongness, urge to neutralize, and how upsetting the event would be if it occurred. Results indicated that thinking of a relative being diagnosed with cancer provoked more distress, urges to neutralize, and higher estimates of likelihood, as well greater use of mental neutralizing behaviors, compared to thinking of a stranger. Contrary to our prediction, the groups did not differ in their ratings of the moral wrongness. These findings broadly support the assertion that the more personally significant a negative intrusive thought, the more it will provoke distress and urges to neutralize. Results are discussed in terms of the cognitive model of obsessions and clinical implications are addressed. Copyright © 2011 Elsevier Ltd. All rights reserved.

Maturity of hospital information systems: Most important influencing factors.

Vidal Carvalho, João; Rocha, Álvaro; Abreu, António

2017-07-01

Maturity models facilitate organizational management, including information systems management, with hospital organizations no exception. This article puts forth a study carried out with a group of experts in the field of hospital information systems management with a view to identifying the main influencing factors to be included in an encompassing maturity model for hospital information systems management. This study is based on the results of a literature review, which identified maturity models in the health field and relevant influencing factors. The development of this model is justified to the extent that the available maturity models for the hospital information systems management field reveal multiple limitations, including lack of detail, absence of tools to determine their maturity and lack of characterization for stages of maturity structured by different influencing factors.

Professional values are abstract and general behavioral principles that provide basic standards to judge aims and actions, and these principles are formed by strong emotional loyalty of members of the profession. Research was conducted to compare the career choice and professional values of nursing students at two universities in the upper Midwest of the United States and in the middle of Turkey. A descriptive and comparative design was used. The participants of the study were comprised nursing students from a university in the upper Midwest of United States and a university in the middle of Turkey. The sample consisted of 728 students in all grades. Data were collected by a questionnaire, The Nurses Professional Values Scale-Revised and Vocational Choices in Entering Nursing Scale. Number, percentage distribution, mean, standard deviation, t test, and one-way variance analysis were used in the analysis of data. Ethical considerations: Ethical approval was obtained from the Ethics Commission. Informed consent was received from the students. The students' mean age for American students was 24.3 ± 5.6 years, while the mean age for Turkish students was 19.8 ± 1.7 years. Mean score of American students on The Vocational Congruency (a subgroup of the Vocational Choices in Entering Nursing Scale) was 38.5 ± 5.9 and Turkish students was 29.6 ± 8.9 (p Values Scale-Revised was 109.2 ± 12.3 and that of Turkish students was 101.6 ± 17.0. This study concluded that the majority of nursing students had high professional values, and when students' scores were compared, American students had higher professional values, and in career choice, they considered primarily fitness of the profession to themselves and their goals, while Turkish students primarily thought of their living conditions.

Ovarian follicle maturation and ovulation: An integrated perspective

Numerous studies with teleosts have addressed the regulation and mechanisms of oocyte maturation, but largely at the exclusion of ovulation. A smaller but still considerable number of studies have focused on ovulation, and ignored maturation. Consequently, little is known about the mechanistic linkages between these two events. New information is presented here indicating that luteinizing hormone regulates the acquisition not only of oocyte maturational competence, but also ovulatory competence. The thesis is presented that maturation and ovulation are closely integrated and overlapping events that are best viewed conceptually and experimentally as parts of a functional whole. ?? 2004 Kluwer Academic Publishers.

Although burnout is associated with erosion of professionalism and serious personal consequences, whether positive mental health can enhance professionalism and how it shapes personal experience remain poorly understood. The study simultaneously explores the relationship between positive mental health and burnout with professionalism and personal experience. The authors surveyed 4,400 medical students at seven U.S. medical schools in 2009 to assess mental health (categorized as languishing, moderate, and flourishing) and burnout. Additional items explored professional behaviors, beliefs, suicidal ideation, and serious thoughts of dropping out. A total of 2,682/4,400 (61%) responded. Prevalence of suicidal ideation (55/114 [48.2%], 281/1,128 [24.9%], and 127/1,409 [9.1%]) and serious thoughts of dropping out (15/114 [13.2%], 30/1,128 [2.7%], and 14/1,409 [1.0%]) decreased as mental health improved from languishing, moderate, and flourishing, respectively (all P mental health persisted independent of burnout (all P mental health improved, the prevalence of unprofessional behaviors (i.e., cheating and dishonest behaviors) also declined, whereas students' altruistic beliefs regarding physicians' responsibility toward society improved. For example, 33/113 (29.2%), 426/1,120 (38.0%), and 718/1,391 (51.6%) of students with languishing, moderate, and flourishing mental health endorsed all five altruistic professional beliefs (P mental health persisted among students with burnout, whereas fewer relationships were found among students without burnout. Findings suggest that positive mental health attenuates some adverse consequences of burnout. Medical student wellness programs should aspire to prevent burnout and promote mental health.

Research purpose: The purpose of this study was to investigate the buying behaviour of mature consumers (older than 55 in Port Elizabeth shopping malls. Motivation for the study: The perception of mature shoppers as old people with limited financial resources is untrue. This study investigates the behaviours of mature shoppers. Research design, approach and method: A model guided the investigation. The authors facilitated four focus groups to gain insight into mature consumers’ buying behaviours. A field survey followed with a sample of mall shoppers (n = 680. The authors performed content analysis of the focus group material and used SPSS and AMOS programs to analyse the data quantitatively. Main findings: Focus group interviews revealed specific buying behaviours of mature shoppers. The survey showed significant relationships between various determinants that influence respondents’ buying behaviours with adequate model fit indices. These results confirmed the convergent and discriminant validity of the model that comprises mall shopping anticipation, experience and patronage. Practical/managerial implications: Mature shoppers’ expectations exceeded their experiences, suggesting dissatisfaction with some aspects of their experiences. Retailers and shopping mall managers need to redesign malls if they wish to cater for the segment of ageing shoppers and their spending power. Contribution/value-add: The study contributes to the research available in South Africa on service at shopping malls that cater for mature consumers.

Full Text Available OBJECTIVE: To analyze the association between physical activity (PA and biological maturation in children and adolescents. DATA SOURCE: We performed a systematic review in April 2013 in the electronic databases of PubMed/MEDLINE, SportDiscus, Web of Science and LILACS without time restrictions. A total of 628 potentially relevant articles were identified and 10 met the inclusion criteria for this review: cross-sectional or longitudinal studies, published in Portuguese, English or Spanish, with schoolchildren aged 9-15 years old of both genders. DATA SYNTHESIS: Despite the heterogeneity of the studies, there was an inverse association between PA and biological maturation. PA decreases with increased biological and chronological age in both genders. Boys tend to be more physically active than girls; however, when controlling for biological age, the gender differences disappear. The association between PA and timing of maturation varies between the genders. Variation in the timing of biological maturation affects the tracking of PA in early adolescent girls. This review suggests that mediators (BMI, depression, low self-esteem, and concerns about body weight can explain the association between PA and biological maturation. CONCLUSIONS: There is an association between PA and biological maturation. PA decreases with increasing biological age with no differences between genders. As for the timing of biological maturation, this association varies between genders.

[Effects of the Internet on the dissemination of medical information: some thoughts on applied ethics].

Science.gov (United States)

Lucas, Jacques

2009-10-01

Learned and professional societies as well as health authorities must attempt to provide free access to their databases for physicians, by a simple repertory of key words and, if necessary, by portals. Although information available for physicians may not be intended to be secret, it often requires some professional training to be interpreted appropriately. The principles of the Code of Medical Ethics, as transcribed in the Public Health Code, apply to all forms and media of information and communication. In public spaces, readers must be guaranteed that information written by physicians corresponds to the state of the art, that it is not advertising or self-promotion or commercial, that it was developed by a process ensuring quality, and that it distinguishes clearly between a popularized description of scientific data and what remains uncertain because research is on-going. The public should be informed about the source of the information they see, the editorial quality of the site, and any potential financial dependence or conflicts of interest. According to the medical association, prudence is recommended for physicians who moderate chat-rooms and discussion lists. List moderation, like any other type of medical activity, must not be improvised; it requires prudence, thought, and training.

1983-01-01

This study estimates the age of biological maturity, defined as the end of adolescent sterility, of Malaysian girls by employing an indiredt methodology. Biological maturity usually occurs about 3 years after puberty. Adolescent subfecundity is due to anovulatory cycles or to short luteal phases among menarchial girls. In this study, age at biological maturity is estimated by considering retrospective fertility and family survey data on marriage, 1st birt, and contraceptive use. The waiting time for the biologically mature females to conceive is 3.0 months; 3.2 months among the Malays, 2.7 months among the Chinese, and 2.8 months among the Indians. The maximum age of attaining biological maturity is 20 for all ethnic groups except Indians (19 years). The maximum age is estimated by considering females whose 1st pregnancy ended in a live birth and who have been living most of the time with their husbands since marriage, with no contraceptive usage. The expected age of biological maturity at birth is 15.6 years; 15.3 years for the Malays, 15.4 years for the Chinese, and 14.8 years for the Indians. The means age of attaining biological maturity coincides with the expected age of attaining biological maturity at birth.

Fudalej, Piotr; Rothe, Laura E; Bollen, Anne-Marie

2008-08-01

Our aim was to test the hypothesis that relapse of incisor alignment is associated with skeletal maturity at the end of treatment, as assessed with the cervical vertebral maturation (CVM) method. This was a case-control study with information from the postretention database at the University of Washington. Mandibular incisor irregularity (II) at least 10 years out of retention (T3) was used to define the subjects (II >6 mm, relapse group) and the controls (II 0.05). Pretreatment II and postretention time were found to be correlated with long-term incisor stability (P = 0.007 and 0.034, respectively). Sex was not related to relapse (P = 0.33). Maturity of craniofacial structures at the end of treatment evaluated with the CVM method is not associated with long-term stability of incisor alignment.

Maturity Model for Advancing Smart Grid Interoperability

Energy Technology Data Exchange (ETDEWEB)

Knight, Mark; Widergren, Steven E.; Mater, J.; Montgomery, Austin

2013-10-28

Abstract—Interoperability is about the properties of devices and systems to connect and work properly. Advancing interoperability eases integration and maintenance of the resulting interconnection. This leads to faster integration, lower labor and component costs, predictability of projects and the resulting performance, and evolutionary paths for upgrade. When specifications are shared and standardized, competition and novel solutions can bring new value streams to the community of stakeholders involved. Advancing interoperability involves reaching agreement for how things join at their interfaces. The quality of the agreements and the alignment of parties involved in the agreement present challenges that are best met with process improvement techniques. The GridWise® Architecture Council (GWAC) sponsored by the United States Department of Energy is supporting an effort to use concepts from capability maturity models used in the software industry to advance interoperability of smart grid technology. An interoperability maturity model has been drafted and experience is being gained through trials on various types of projects and community efforts. This paper describes the value and objectives of maturity models, the nature of the interoperability maturity model and how it compares with other maturity models, and experiences gained with its use.

Two studies were conducted to further explore this phenomenon and to establish the psychometric properties of a French short version of the TSF scale. In Study 1, students (n = 284) completed questionnaires assessing TSF and related psychopathology. In Study 2, the responses of women with eating disorders (n = 22) and women with no history of an eating disorder (n = 23) were compared. The French short version of the TSF scale has a unifactorial structure, with convergent validity with measures of eating pathology, and good internal consistency. Depression, eating pathology, body dissatisfaction, and thought-action fusion emerged as predictors of TSF. Individuals with eating disorders have higher TSF, and more clinically relevant food-related thoughts than do women with no history of an eating disorder. This research suggests that the shortened TSF scale can suitably measure this construct, and provides support for the notion that TSF is associated with eating pathology.

Studying scientific thought experiments in their context: Albert Einstein and electromagnetic induction

Science.gov (United States)

Potters, Jan; Leuridan, Bert

2017-05-01

This article concerns the way in which philosophers study the epistemology of scientific thought experiments. Starting with a general overview of the main contemporary philosophical accounts, we will first argue that two implicit assumptions are present therein: first, that the epistemology of scientific thought experiments is solely concerned with factual knowledge of the world; and second, that philosophers should account for this in terms of the way in which individuals in general contemplate these thought experiments in thought. Our goal is to evaluate these assumptions and their implications using a particular case study: Albert Einstein's magnet-conductor thought experiment. We will argue that an analysis of this thought experiment based on these assumptions - as John Norton (1991) provides - is, in a sense, both misguided (the thought experiment by itself did not lead Einstein to factual knowledge of the world) and too narrow (to understand the thought experiment's epistemology, its historical context should also be taken into account explicitly). Based on this evaluation we propose an alternative philosophical approach to the epistemology of scientific thought experiments which is more encompassing while preserving what is of value in the dominant view.

Appraisal and control of sexual and non-sexual intrusive thoughts in university students.

Science.gov (United States)

Clark, D A; Purdon, C; Byers, E S

2000-05-01

This study examined differences in the appraisal and thought control strategies associated with the perceived control of unwanted sexual and non-sexual intrusive thoughts. Eleven appraisal dimensions, subjective physiological arousal and 10 thought control strategies were measured in 171 university students who were administered the Revised Obsessive Intrusions Inventory-Sex Version, a self-report measure of unwanted intrusive thoughts. Thought-action fusion (TAF) likelihood was a significant unique predictor of the perceived controllability of respondents' most upsetting sexual and non-sexual intrusive thought. Moreover greater subjective physiological arousal was a significant predictor of reduced control over sexual intrusions, whereas worry that one might act on an intrusive thought and greater effort to control the intrusion were significant unique predictors of the control of non-sexual intrusive thoughts. Various thought control strategies were more often used in response to non-sexual than sexual cognitions. The results are discussed in terms of the differential role of various appraisal processes in the control of unwanted sexual and non-sexual thoughts.

Wittgenstein's True Thoughts

Directory of Open Access Journals (Sweden)

Andrew Lugg

2013-03-01

Full Text Available The central remarks of the Tractatus are without substantial content or consequence, remarks at the boundaries of sense that dissolve into truth.  While they say nothing, they encapsulate logical features of the language and the world.  Unasserted, they express thoughts, the truth of which Wittgenstein takes to be unassailable and definitive.  Asserted, they are out-and-out nonsense.  What is manifest in linguistic practice is no more sayable – and no less significant – than what is manifest in logical truths, mathematical equations and the principles of mechanics.

Genetic transformation of mature citrus plants.

Cervera, Magdalena; Juárez, José; Navarro, Luis; Peña, Leandro

2005-01-01

Most woody fruit species have long juvenile periods that drastically prolong the time required to analyze mature traits. Evaluation of characteristics related to fruits is a requisite to release any new variety into the market. Because of a decline in regenerative and transformation potential, genetic transformation procedures usually employ juvenile material as the source of plant tissue, therefore resulting in the production of juvenile plants. Direct transformation of mature material could ensure the production of adult transgenic plants, bypassing in this way the juvenile phase. Invigoration of the source adult material, establishment of adequate transformation and regeneration conditions, and acceleration of plant development through grafting allowed us to produce transgenic mature sweet orange trees flowering and bearing fruits in a short time period.

Low-maturity Kulthieth Formation coal: A possible source of polycyclic aromatic hydrocarbons in benthic sediment of the northern Gulf of Alaska

Science.gov (United States)

Van Kooten, G. K.; Short, J.W.; Kolak, J.J.

2002-01-01

The successful application of forensic geology to contamination studies involving natural systems requires identification of appropriate endmembers and an understanding of the geologic setting and processes affecting the systems. Studies attempting to delineate the background, or natural, source for hydrocarbon contamination in Gulf of Alaska (GOA) benthic sediments have invoked a number of potential sources, including seep oils, source rocks, and coal. Oil seeps have subsequently been questioned as significant sources of hydrocarbons present in benthic sediments of the GOA in part because the pattern of relative polycyclic aromatic hydrocarbon (PAH) abundance characteristic of benthic GOA sediments is inconsistent with patterns typical of weathered seep oils. Likewise, native coal has been dismissed in part because ratios of labile hydrocarbons to total organic carbon (e.g. PAH:TOC) for Bering River coal field (BRCF) sources are too low - i.e. the coals are over mature - to be consistent with GOA sediments. We present evidence here that native coal may have been prematurely dismissed, because BRCF coals do not adequately represent the geochemical signatures of coals elsewhere in the Kulthieth Formation. Contrary to previous thought, Kulthieth Formation coals east of the BRCF have much higher PAH: TOC ratios, and the patterns of labile hydrocarbons in these low thermal maturity coals suggest a possible genetic relationship between Kulthieth Formation coals and nearby oil seeps on the Sullivan anticline. Analyses of low-maturity Kulthieth Formation coal indicate the low maturity coal is a significant source of PAH. Source apportionment models that neglect this source will underestimate the contribution of native coals to the regional background hydrocarbon signature. ??

2016-11-01

Full Text Available Objective. The aims of this study were: to investigate the relationship between mandibular canine calcification stages and skeletal maturity; and to evaluate whether the mandibular canine calcification stages may be used as a reliable diagnostic tool for skeletal maturity assessment. Materials and methods. This study included 151 subjects: 81 females and 70 males, with ages ranging from 9 to 16 years (mean age: 12.29±1.86 years. The inclusion criteria for subjects were as follows: age between 9 and 16 years; good general health without any hormonal, nutritional, growth or dental development problems. Subjects who were undergoing or had previously received orthodontic treatment were not included in this study. The calcification stages of the left permanent mandibular canine were assessed according to the method of Demirjian, on panoramic radiographs. Assessment of skeletal maturity was carried out using the cervical vertebral maturation index (CVMI, as proposed by the Hassel-Farman method, on lateral cephalograms. The correlation between the calcification stages of mandibular canine and skeletal maturity was estimated separately for male and female subjects. Results. Correlation coefficients between calcification stages of mandibular canine and skeletal maturity were 0.895 for male and 0.701 for female subjects. Conclusions. A significant correlation was found between the calcification stages of the mandibular canine and skeletal maturity. The calcification stages of the mandibular canine show a satisfactory diagnostic performance only for assessment of pre-pubertal growth phase.

Measuring interoperable EHR adoption and maturity: a Canadian example.

Science.gov (United States)

Gheorghiu, Bobby; Hagens, Simon

2016-01-25

An interoperable electronic health record is a secure consolidated record of an individual's health history and care, designed to facilitate authorized information sharing across the care continuum.  Each Canadian province and territory has implemented such a system and for all, measuring adoption is essential to understanding progress and optimizing use in order to realize intended benefits. About 250,000 health professionals-approximately half of Canada's anticipated potential physician, nurse, pharmacist, and administrative users-indicated that they electronically access data, such as those found in provincial/territorial lab or drug information systems, in 2015.  Trends suggest further growth as maturity of use increases. There is strong interest in health information exchange through the iEHR in Canada, and continued growth in adoption is expected. Central to managing the evolution of digital health is access to robust data about who is using solutions, how they are used, where and when.  Stakeholders such as government, program leads, and health system administrators must critically assess progress and achievement of benefits, to inform future strategic and operational decisions.

Mature neurons dynamically restrict apoptosis via redundant premitochondrial brakes.

2016-12-01

Apoptotic cell death is critical for the early development of the nervous system, but once the nervous system is established, the apoptotic pathway becomes highly restricted in mature neurons. However, the mechanisms underlying this increased resistance to apoptosis in these mature neurons are not completely understood. We have previously found that members of the miR-29 family of microRNAs (miRNAs) are induced with neuronal maturation and that overexpression of miR-29 was sufficient to restrict apoptosis in neurons. To determine whether endogenous miR-29 alone was responsible for the inhibition of cytochrome c release in mature neurons, we examined the status of the apoptotic pathway in sympathetic neurons deficient for all three miR-29 family members. Unexpectedly, we found that the apoptotic pathway remained largely restricted in miR-29-deficient mature neurons. We therefore probed for additional mechanisms by which mature neurons resist apoptosis. We identify miR-24 as another miRNA that is upregulated in the maturing cerebellum and sympathetic neurons that can act redundantly with miR-29 by targeting a similar repertoire of prodeath BH3-only genes. Overall, our results reveal that mature neurons engage multiple redundant brakes to restrict the apoptotic pathway and ensure their long-term survival. © 2016 Federation of European Biochemical Societies.

Recording thoughts while memorizing music: a case study

Lisboa, Tania; Chaffin, Roger; Demos, Alexander P.

2015-01-01

Musicians generally believe that memory differs from one person to the next. As a result, memorizing strategies that could be useful to almost everyone are not widely taught. We describe how an 18-years old piano student (Grade 7, ABRSM), learned to memorize by recording her thoughts, a technique inspired by studies of how experienced soloists memorize. The student, who had previously ignored suggestions that she play from memory, decided to learn to memorize, selecting Schumann’s “Der Dichter Spricht” for this purpose. Rather than explicitly teaching the student how to memorize, the teacher taught her to record her thoughts while playing by marking them on copies of the score, adapting an approach used previously in research with experienced performers. Over a 6½ week period, the student recorded her thoughts during practice (five times) and while performing from memory for the teacher (three times). The student also video-recorded 3 weeks of practice, three performances, and the reconstruction of the piece from memory after a 9½-weeks break. The thoughts that the student reported were prepared during practice, stable over time, and functioned as memory retrieval cues during reconstruction. This suggests that the student memorized in the same way as the more experienced musicians who have been studied previously and that teaching student musicians to record their thoughts may be an effective way to help them memorize. The speed and durability of her memorization surprised the student, inspiring her to perform in public and to use the same technique for new pieces. PMID:25667574

Thought-action fusion as a causal factor in the development of intrusions.

Science.gov (United States)

Rassin, E; Merckelbach, H; Muris, P; Spaan, V

1999-03-01

Thought-action fusion refers to the tendency to treat thoughts and actions as equivalents. Some authors (e.g., Rachman, 1997; Behaviour Research and Therapy, 35, 793-802) have suggested that thought-action fusion plays a role in the etiology of obsessive intrusions. The present study sought to test this idea. Subjects (n = 19) in the experimental condition underwent a bogus EEG recording session. They were informed that the apparatus was able to pick up the word 'apple' and that thoughts of that word could result in the administration of electrical shocks to another person. After having spent 15 minutes in the EEG laboratory, experimental subjects and controls (n = 26) completed a short questionnaire containing items about characteristics of the target thought (e.g., frequency, aversiveness). Results indicate that thought-action fusion, indeed, promotes intrusive thinking in that it results in a higher frequency of target thoughts, more discomfort, and more resistance. Thus, the current findings support the idea that thought-action fusion may contribute to the development of obsessive intrusions.

Body image concerns in professional fashion models: are they really an at-risk group?

Swami, Viren; Szmigielska, Emilia

2013-05-15

Although professional models are thought to be a high-risk group for body image concerns, only a handful of studies have empirically investigated this possibility. The present study sought to overcome this dearth of information by comparing professional models and a matched sample on key indices of body image and appeared-related concerns. A group of 52 professional fashion models was compared with a matched sample of 51 non-models from London, England, on indices of weight discrepancy, body appreciation, social physique anxiety, body dissatisfaction, drive for thinness, internalization of sociocultural messages about appearance, and dysfunctional investment in appearance. Results indicated that professional models only evidenced significantly higher drive for thinness and dysfunctional investment in appearance than the control group. Greater duration of engagement as a professional model was associated with more positive body appreciation but also greater drive for thinness. These results indicate that models, who are already underweight, have a strong desire to maintain their low body mass or become thinner. Taken together, the present results suggest that interventions aimed at promoting healthy body image among fashion models may require different strategies than those aimed at the general population.

2017-01-01

Full Text Available A systematic literature review of supply chain maturity models with sustainability concerns is presented. The objective is to give insights into methodological issues related to maturity models, namely the research objectives; the research methods used to develop, validate and test them; the scope; and the main characteristics associated with their design. The literature review was performed based on journal articles and conference papers from 2000 to 2015 using the SCOPUS, Emerald Insight, EBSCO and Web of Science databases. Most of the analysed papers have as main objective the development of maturity models and their validation. The case study is the methodology that is most widely used by researchers to develop and validate maturity models. From the sustainability perspective, the scope of the analysed maturity models is the Triple Bottom Line (TBL and environmental dimension, focusing on a specific process (eco-design and new product development and without a broad SC perspective. The dominant characteristics associated with the design of the maturity models are the maturity grids and a continuous representation. In addition, results do not allow identifying a trend for a specific number of maturity levels. The comprehensive review, analysis, and synthesis of the maturity model literature represent an important contribution to the organization of this research area, making possible to clarify some confusion that exists about concepts, approaches and components of maturity models in sustainability. Various aspects associated with the maturity models (i.e., research objectives, research methods, scope and characteristics of the design of models are explored to contribute to the evolution and significance of this multidimensional area.

Using Smith's (1986) cognitive-affective model of athletic burnout as a guiding framework, the purpose of this study was to examine the relationships among athletes' stress in life, negative thoughts, and the mediating role of negative thoughts on the stress-burnout relationship. A total of 300 college student-athletes (males = 174; females = 126, M age  = 20.43 y, SD = 1.68) completed the College Student Athlete's Life Stress Scale (CSALSS; Lu et al., 2012), the Automatic Thoughts Questionnaire (ATQ; Hollon & Kendall, 1980), and the Athlete Burnout Questionnaire (ABQ; Raedeke & Smith, 2001). Correlational analyses found that two types of life stress and four types of negative thoughts correlated with burnout. Additionally, hierarchical regression analyses found that four types of negative thoughts partially mediated the stress-burnout relationship. We concluded that an athlete's negative thoughts play a pivotal role in predicting athletes' stress-burnout relationship. Future study may examine how irrational cognition influences athletes' motivation and psychological well-being.

2016-08-01

Preschool identification of and intervention for psychiatric symptoms has the potential for lifelong benefits. However, preschool identification of thought disorder, a symptom associated with long term risk for social and cognitive dysfunction, has received little attention with previous work limited to examining preschoolers with severe emotional and behavioral dysregulation. Using story-stem methodology, 12 children with ADHD and 12 children without ADHD, ages 4.0-6.0 years were evaluated for thought disorder. Thought disorder was reliably assessed (Cronbach's alpha = .958). Children with ADHD were significantly more likely than children without ADHD to exhibit thought disorder (75 vs 25 %; Fischer's Exact Test = .0391). Thought disorder can be reliably assessed in preschool children and is present in preschool children with psychiatric illness including preschool children with ADHD. Thought disorder may be identifiable in preschool years across a broad range of psychiatric illnesses and thus may be an appropriate target of intervention.

The aim of this study was to investigate the relationships between the stages of calcification of teeth and the cervical vertebral maturity stages in Turkish subjects. A retrospective cross-sectional study was designed. The final study population consisted of 590 Turkish subjects. Statistical analysis of the data was performed with computer software. Spearman rank order correlation coefficients were used to assess the relationship between cervical vertebral and dental maturation. For a better understanding of the relationship between cervical vertebral maturation indexes and dental age, percentage distributions of the studied teeth were also calculated. Strict correlations were found between dental and cervical vertebral maturation of Turkish subjects. For males, the sequence from lowest to the highest was third molar, central incisor, canine, first premolar, second premolar, first molar, and second molar. For females, the sequence from lowest to the highest was third molar, canine, second premolar, first premolar, central incisor, first molar, and second molar. Dental maturation stages can be used as a reliable indicator of facial growth.

Full Text Available The book of V.A. Kitaev includes reviews of monographs and textbook, collective publications, including encyclopedias, publications of sources, historiographical articles, some of which were published in leading scientific journals in 1980-2015, and some were published for the first time. This publication is not exactly a review to V.A. Kitaev’s book, but an attempt to provide the reader with reflections on some of the problems of public thoughts and historiography highlighted by the author: the features of the professional study of history, historiographical analysis as a genre of research, methodology and terminology in modern studies on the history of social thought and historical science, the ratio of professional approach and political convictions, attitude to scientific traditions, etc. The present paper highlights the highest scientific professionalism of V.A. Kitaev, his ability and willingness to be critical not only to other people’s research, but also to his own. Despite the well-known assertion that “we do not choose the times”, we can safely say that V.A. Kitaev consciously chose the “time of the historian” and found himself in this time.

Craniofacial growth, maturation, and change: teens to midadulthood.

Ross, Ann H; Williams, Shanna E

2010-03-01

Despite the attainment of several adult cranial dimensions relatively early in childhood, skeletal maturity and, by consequence, adult form are typically defined by the eruption of the third molars around 17 years of age. This in turn serves as the division between subadults and adults, which is then applied to population studies of biological variation. Specifically, comparative data sets of adult measurements are not directly applied to individuals who do not have complete skeletal growth, as it is believed that the confounding effects of allometry may skew the results. The present study uses geometric morphometrics techniques to investigate the appropriateness of this division with respect to three-dimensional anatomical landmarks. Twenty-six landmarks were collected from a single population of 24 crania partitioned into 4 age groups spanning late adolescence to midadulthood. Generalized Procrustes and multivariate statistical analyses were performed on the landmark data. Results showed no significant morphological differences between the teen and young adult age groups, whereas significant shape and size differences were found in older adults relative to their younger cohorts. Moreover, no growth-related shape variation (ie, allometry) was detected within the sample. These findings suggest that adult form is attained several years earlier than commonly thought and corroborate other research that suggest that subtle changes in cranial morphology continue throughout adulthood.

The timing of lung maturation is controlled precisely by complex genetic and cellular programs. Lung immaturity following preterm birth frequently results in Respiratory Distress Syndrome (RDS) and Broncho-Pulmonary Dysplasia (BPD), which are leading causes of mortality and morbidity in preterm infants. Mechanisms synchronizing gestational length and lung maturation remain to be elucidated. In this study, we designed a genome-wide mRNA expression time-course study from E15.5 to Postnatal Day 0 (PN0) using lung RNAs from C57BL/6J (B6) and A/J mice that differ in gestational length by ∼30 hr (B6controlling lung maturation. We identified both temporal and strain dependent gene expression patterns during lung maturation. For time dependent changes, cell adhesion, vasculature development, and lipid metabolism/transport were major bioprocesses induced during the saccular stage of lung development at E16.5–E17.5. CEBPA, PPARG, VEGFA, CAV1 and CDH1 were found to be key signaling and transcriptional regulators of these processes. Innate defense/immune responses were induced at later gestational ages (E18.5–20.5), STAT1, AP1, and EGFR being important regulators of these responses. Expression of RNAs associated with the cell cycle and chromatin assembly was repressed during prenatal lung maturation and was regulated by FOXM1, PLK1, chromobox, and high mobility group families of transcription factors. Strain dependent lung mRNA expression differences peaked at E18.5. At this time, mRNAs regulating surfactant and innate immunity were more abundantly expressed in lungs of B6 (short gestation) than in A/J (long gestation) mice, while expression of genes involved in chromatin assembly and histone modification were expressed at lower levels in B6 than in A/J mice. The present study systemically mapped key regulators, bioprocesses, and transcriptional networks controlling lung maturation, providing the basis for new therapeutic strategies to enhance lung function in preterm

Full Text Available Objective – This article presents the findings of a project which established an empirical basis for evidence based library and information practice (EBLIP. More specifically, the paper explores what library and information professionals experienced as evidence in the context of their professional practice. Methods – The project consisted of two sub-studies. The public library sub-study was conducted using ethnography. Over a 5-month period, a member of the research team travelled to a regional public library on 15 occasions, staying between 3 and 4 days on each visit. The researcher observed, interacted, and became involved in the day-to-day activities of this library. These activities were recorded in a journal and added to the researcher’s insights and thoughts. Additionally, 13 face-to-face interviews with staff in positions ranging from the operational to the executive were conducted. The academic sub-study was conducted using Constructivist Grounded Theory. Semi-structured interviews were conducted either in person or via Skype, with 13 librarians from Australian universities. Interviewees were in a diverse array of roles, from liaison librarian to manager and library director. Results – The project found that the Australian academic librarians and the public librarians who participated in the project experienced six elements as evidence: observation, feedback, professional colleagues, research literature, statistics, and intuition. Each of these will be described and highlighted with examples from each of the two studies. Conclusions – The findings of this study revealed many similarities in the way that library professionals from both studies experienced evidence. Evidence was not hierarchical, with evidence from many sources being valued equally. In contextualizing evidence and applying to the local environment, library professionals were able to draw upon more than one source of evidence and apply their professional knowledge

Full Text Available Background: Immature oocyte retrieval followed by in vitro maturation is a promising infertility treatment option. In patients with morphologically normal ovaries and regular menstrual cycles and in patients with polycystic ovary syndrome (PCOS we attempted to assess the success of oocyte in vitro maturation in in vitro fertilization (IVF procedures.Methods: Retrospectively we analyzed 87 IVF procedures with in vitro maturation of oocytes carried out in 73 infertile couples treated at the Maribor Teaching Hospital. We compared the success following three different hormone priming protocols: regular cycling patients with normal ovaries and without hormone priming (Group A, n = 27; patients with PCOS and hormone priming with follitropin (follicle stimulating hormone, FSH (Group B, n = 22; patients with PCOS and hormone priming with human chorionic gonadotrophin (hCG (Group C, n = 38. Success of the procedure was evaluated on the basis of the ability of oocytes to mature, fertilize and develop into embryos, and on the basis of the quality of embryos and their ability to implant in the uterus.Results: In regular cycling patients with normal ovaries (n = 27 we obtained a significantly lower number of immature oocytes (3.2 ± 2.5 compared with patients with PCOS and FSH priming (11.7 ± 7.2 or those with PCOS and hCG priming (10.4 ± 7.2. The oocyte maturation rate, the fertilization rate and the embryo cleavage rate were as follows: in Group A 57.7 %, 63.2 % and 91.7 %, in Group B 57.6 %, 66.2 % and 90.0 %, and in Group C 58.0 %, 66.2 % and 91.0 % (the differences between groups were not statistically significant. Six pregnancies were recorded only in patients with PCOS. The pregnancy rate per embryo transfer was 1/20 (5.0 % in patients with FSH priming, and 5/33 (15.2 % in patients with hCG priming.Conclusions: Oocyte in vitro maturation is successful in patients with normal ovaries and regular menstrual cycle as well as in those with polycystic

Full Text Available This paper investigates the determinants of loan maturity of small and medium enterprises (SMEs in the context of Visegrad countries: Czech Republic, Slovak Republic, Poland, and Hungary. The data of instead of for this paper was obtained from the Business Environment and Enterprise Performance Survey (BEEPS, which is a joint project of the European Bank for Reconstruction and Development and the World Bank. By using a binary logistic model, we have found that loan maturity is shorter for older and mature firms, firms owned by female and firms experiencing a shortage of liquidity. At the same time, we have also found that firms having concentrated ownership structure and more tangible assets can borrow for a longer period. In addition to that, we have found evidence that loan maturity is longer for the firms located closer to a bank branch. We also provide empirical support for the assumption that bank low competition is associated with longer maturity. From the obtained results, we may recommend SMEs to borrow from banks that are within their vicinity since this may increase the maturity of loans. Policy makers are recommended to implement policies so that to alleviate gender-related discrimination and take initiatives to moderate the level of competition at this market.

Full Text Available Abstract Background and Objectives: Considering that paranoid thought has one-dimensional approach, use of long questionnaires has no clinical and research application, therefore use of short questionnaires seems necessary. The Green et al. paranoid thought scale is a short self-assessment tool for assessing paranoid thought in non-clinical and clinical group. This research was conducted to validate this questionnaire in Iranian population. Methods: In this cross-sectional survey, 356 students were selected using stratified sampling method and assessed by GPTS and Minnesota multiphasic paranoid inventory (MMPI in 2015. Validity was assessed simultaneously with MMPI testing. Results: The correlation coefficient of GPTS and MMPI scores was α=0.71 and significant (p<0.001. Internal consistency value was estimated to be 0.81 according to Cronbach's alpha coefficient. Conclusion: GPTS is an appropriate and short tool for screening in paranoid thought-related researches.

Full Text Available Characteristics of late maturity in fruit are good agronomic traits for extending the harvest period and marketing time. However, underlying molecular basis of the late-maturing mechanism in fruit is largely unknown. In this study, RNA sequencing (RNA-Seq technology was used to identify differentially expressed genes (DEGs related to late-maturing characteristics from a late-maturing mutant ‘Huawan Wuzishatangju’ (HWWZSTJ (Citrus reticulata Blanco and its original line ‘Wuzishatangju’ (WZSTJ. A total of approximately 17.0 Gb and 84.2 M paried-end reads were obtained. DEGs were significantly enriched in the pathway of photosynthesis, phenylpropanoid biosynthesis, carotenoid biosynthesis, chlorophyll and abscisic acid (ABA metabolism. Thirteen candidate transcripts related to chlorophyll metabolism, carotenoid biosynthesis and ABA metabolism were analyzed using real-time quantitative PCR (qPCR at all fruit maturing stages of HWWZSTJ and WZSTJ. Chlorophyllase (CLH and divinyl reductase (DVR from chlorophyll metabolism, phytoene synthase (PSY and capsanthin/capsorubin synthase (CCS from carotenoid biosynthesis, and abscisic acid 8′-hydroxylase (AB1 and 9-cis-epoxycarotenoid dioxygenase (NCED1 from ABA metabolism were cloned and analyzed. The expression pattern of NCED1 indicated its role in the late-maturing characteristics of HWWZSTJ. There were 270 consecutive bases missing in HWWZSTJ in comparison with full-length sequences of NCED1 cDNA from WZSTJ. Those results suggested that NCED1 might play an important role in the late maturity of HWWZSTJ. This study provides new information on complex process that results in the late maturity of Citrus fruit at the transcriptional level.

Professionals involved in assisted reproductive technologies (ART) have in-depth awareness and knowledge of the risks of multiple pregnancies at the conclusion of in vitro fertilization (IVF) treatment. The aim of the study was to investigate ART professionals' attitudes towards the awareness of the risk of infertility, as well as the decision-making process in IVF issues. Seventy ART professionals answered a questionnaire covering demographic data, infertility awareness and attitudes towards IVF. Approximately half (50.8%) of the participants thought that they were not at risk of infertility. However, if they received a diagnosis of infertility, none would accept childlessness and almost all would undergo IVF. In an IVF cycle, the number of high-quality embryos transferred would be around three, but if treatment was extended to a third cycle, a higher percentage of participants would elect to transfer four or more embryos. All participants would prefer to undergo IVF and accept the risk of multiple pregnancy than remaining childless. It was found that less than a third of ART professionals considered triplets to be an unacceptable complication of IVF. Diagnosis of infertility affects all participants psychosocially, supporting the idea that the emotional aspects of wanting a biological child, and decision making about whether to undertake ART, outweigh the medical position regarding the risks and benefits of IVF.

Fetal pulmonary maturation may be a variable event depending on various feto-maternal environmental and biochemical influences. The patterns of maturation were studied in 211 amniotic fluid samples from 123 patients (normal 55; diabetes 23; Rh sensitization 19; preeclampsia 26). The phenomenon of globule formation from the amniotic fluid lipid extract and is relation to pulmonary maturity was utilized for this analysis. Validation of this technique is presented. A normal curve was constructed from 22 to 42 weeks; gestation and compared to the abnormal pregnancies. Patients with class A, B, and C diabetes and Rh-sensitized pregnancies had delayed pulmonary maturation. Patients with class D diabetes and preclampsia paralleled the normal course of maturation. A discussion of these results and their possible cause is presented.

2009-07-01

Full Text Available This study follows two aims: one to review some late views on the relations among language, thought, and culture; and the other, to offer a new strategy, in a novel model, based on last achievements in the minimalist approach. Studying views and arguments, three dichotomies are discussed: 1 the views which confirm the relation between culture and language in opposition to the views that deny this; 2 distinguishing the symmetry-procedural view and the transforming views of language; and 3 distinction among the social-communicational, and the biological-genetic motivations of language. The hypothesis for the novel strategy is that considering what the minimalist program has offered, especially from 2000 onwards, it is possible that language affects thought, while coding the and that culture affects language (which is called ethno-grammar . This is in addition to the biological-genetic base. From this point of view, language’s main function is neither to provide communication, nor to express thought, but to connect cognitive and socio-cultural terminals together.

Chromatin maturation depends on continued DNA-replication

Schlaeger, E.J.; Puelm, W.; Knippers, R.

1983-01-01

The structure of [ 3 H]thymidine pulse-labeled chromatin in lymphocytes differs from that of non-replicating chromatin by several operational criteria which are related to the higher nuclease sensitivity of replicating chromatin. These structural features of replicating chromatin rapidly disappear when the [ 3 H]thymidine pulse is followed by a chase in the presence of an excess of non-radioactive thymidine. However, when the rate of DNA replication is reduced, as in cycloheximide-treated lymphocytes, chromatin maturation is retarded. No chromatin maturation is observed when nuclei from pulse-labeled lymphocytes are incubated in vitro in the absence of DNA precursors. In contrast, when these nuclei are incubated under conditions known to be optimal for DNA replication, the structure of replicating chromatin is efficiently converted to that of 'mature', non-replicating chromatin. The authors conclude that the properties of nascent DNA and/or the distance from the replication fork are important factors in chromatin maturation. (Auth.)

Often, eHealth services are not accepted because of factors such as eHealth literacy or trust. Within this study, eHealthMonitor was evaluated in three European countries (Germany, Greece, and Poland) by medical professionals and laypersons with respect to numerous acceptance factors. Questionnaires were created on the basis of factors from literature and with the help of scales which have already been validated. A qualitative survey was conducted in Germany, Poland, and Greece. The eHealth literacy of all participants was medium/high. Laypersons mostly agreed that they could easily become skillful with eHealthMonitor and that other people thought that they should use eHealthMonitor. Amongst medical professionals, a large number were afraid that eHealthMonitor could violate their privacy or the privacy of their patients. Overall, the participants thought that eHealthMonitor was a good concept and that they would use it. The main hindrances to the use of eHealthMonitor were found in trust issues including data privacy. In the future, more research on the linkage of all measured factors is needed, for example, to address the question of whether highly educated people tend to mistrust eHealth information more than people with lower levels of education.

The importance of the diet in modulating mental health is uncovering as many dietary factors have been described to alter brain chemistry. Brain maturation may not complete until the age of 30 which may explain the differential emotional control, mindset, and resilience between young adults and matured adults. As a result, dietary factors may influence mental health differently in these two populations. To study dietary intake, dietary practices and exercise in young adults (YA) (18-29 years) versus matured adults (MA) (30 years and older) in relation to mental distress. Another aim was to assess whether mental well-being potentially stimulates healthy eating, healthy practices, and exercising. An anonymous internet-based survey was sent through social media platforms to different professional and social group networks. Best-fit models were constructed using the backward regression analysis to assess the relationship between dietary variables, exercise, and mental distress in YA versus MA. YA mood seems to be dependent on food that increases availability of neurotransmitter precursors and concentrations in the brain (such as frequent meat consumption and exercise, respectively). However, MA mood may be more reliant on food that increases availability of antioxidants (fruits) and abstinence of food that inappropriately activates the sympathetic nervous system (coffee, high glycemic index, and skipping breakfast). Level of brain maturation and age-related changes in brain morphology and functions may necessitate dietary adjustments for improving mental well-being.

Full Text Available Introduction. Nowadays, modern students graduate from higher education institutions in the conditions of unwarranted employment, and they are given full freedom of the professional choice after graduation. The aim of the research is to describe the process of the professional choice among graduates with an accredited bachelor degree as a prognostic task solution. Methodology and research methods. The research is based on the analysis and generalization of research literature on the issues of professional self-determination, the theory of anticipation, forecasting psychology, and modeling of predictive activity at the speech-thought level. The method of experiment was used as an empirical method wherein the predictive task was the stimulus material. Results and scientific novelty. The characteristic of a predictive task is given. The authors’ technique «Predictive Task: Professional Choice» is briefly presented; empirical data on professional intentions of graduates with a bachelors degree were collected during the approbation. The weakest links of the professional choice process among the students are revealed as follows: a lack of relevant system information for implementation of the professional choice; incompleteness  of professional self-identification and hypothetical thinking among students during their training in higher education institutions. Thus, the directions of further studies of professional self-determination of university graduates are planned: identification of psychological determinants; comparison of initial attitudes of employment of students of federal and regional higher education institutions; analysis of features of the professional choice of graduates of various specialties. Practical significance. The materials of the present research can form the basis for development of the practical recommendations to optimize pedagogical maintenance of professional self-determination of students of higher education

Various methods have been proposed to evaluate a patient's developmental status. However, most of them lacked precision and failed to give a reliable estimate of skeletal maturity. The aims of this study were to evaluate the association between frontal sinus morphology and cervical vertebral maturation for the assessment of skeletal maturity and to determine its validity in assessing the different stages of the adolescent growth spurt. A cross-sectional study was performed on the pretreatment lateral cephalograms of 252 subjects aged 8 to 21 years. The sample was divided into 6 groups based on the cervical vertebral maturation stages. The frontal sinus index was calculated by dividing the frontal sinus height and width, and the cervical stages were evaluated on the same radiograph. The Kruskal-Wallis test was applied to compare frontal sinus index values at different cervical stages, and the post hoc Dunnett T3 test was applied to compare frontal sinus index values between adjacent cervical stages for each sex. The Kendall tau-b values were computed to assess the correlation between the cervical stages and the sinus index. A P value of ≤0.05 was considered statistically significant. The height and width of the frontal sinus were significantly larger in the male subjects than in the females. A significant association was found between the frontal sinus height and width and cervical stages (P ≤0.001) in both sexes. However, the changes in the frontal sinus index across the different cervical stages were found to be significant (P ≤0.001) in male subjects only. Similarly, a weak negative correlation was found between the sinus index and the cervical stages in male subjects (tau-b = -0.271; P cervical stages. The frontal sinus index cannot be used to identify the prepubertal, pubertal, and postpubertal stages of the adolescent growth spurt. Therefore, it cannot be used as a reliable maturity indicator.

Determination of the maturation level and the subsequent evaluation of growth potential during preadolescence and adolescence are important for optimal orthodontic treatment planning and timing. This study was undertaken to evaluate the applicability of insulin-like growth factor I (IGF-I) blood level as a maturation indicator by correlating it to the cervical vertebral maturation index. The study was conducted with 120 subjects, equally divided into 60 males (ages, 10-18 years) and 60 females (ages, 8-16 years). A lateral cephalometric radiograph and a blood sample were taken from each subject. For each subject, cervical vertebral maturation and IGF-I serum level were assessed. Mean values of IGF-I in each stage of cervical vertebral maturation were calculated, and the means in each stage were statistically compared with those of the other stages. The IGF-I mean value at each cervical vertebral maturation stage was statistically different from the mean values at the other stages. The highest mean values were observed in stage 4, followed by stage 5 in males and stage 3 in females. IGF-I serum level is a reliable maturation indicator that could be applied in orthodontic diagnosis. Copyright © 2012 American Association of Orthodontists. Published by Mosby, Inc.

2009-08-01

Self-awareness of one's own reactions towards patients and their relatives is of paramount importance for all professionals in palliative care. 'Core attitude' describes the way in which a person perceives himself and the world, and forms the basis for his actions and thoughts. The aim of this study is to explore what core attitude means for palliative care professionals and whether there is a specific core attitude in palliative care. Qualitative study with 10 face-to-face in-depth interviews with experts in palliative care (nurses, physicians, social workers, psychologists, chaplain) in Germany. Core attitude in palliative care can be best described with the following three domains: 1) personal characteristics; 2) experience of care; and 3) competence in care. Authenticity is the most important characteristic of professionals, along with honesty and mindfulness. Core attitude primarily becomes apparent in the relationship with the patient. Perception and listening are key competences. The experts emphasized the universality of the core attitude in the care of ill people. They stressed the importance and relevance of teaching core attitudes in palliative care education. In the field of palliative care, core attitude consists predominately of authenticity, manifests itself in relationships, and requires a high degree of perceptiveness.

Full Text Available Background Using Smith’s (1986 cognitive-affective model of athletic burnout as a guiding framework, the purpose of this study was to examine the relationships among athletes’ stress in life, negative thoughts, and the mediating role of negative thoughts on the stress-burnout relationship. Methods A total of 300 college student-athletes (males = 174; females = 126, Mage = 20.43 y, SD = 1.68 completed the College Student Athlete’s Life Stress Scale (CSALSS; Lu et al., 2012, the Automatic Thoughts Questionnaire (ATQ; Hollon & Kendall, 1980, and the Athlete Burnout Questionnaire (ABQ; Raedeke & Smith, 2001. Results Correlational analyses found that two types of life stress and four types of negative thoughts correlated with burnout. Additionally, hierarchical regression analyses found that four types of negative thoughts partially mediated the stress-burnout relationship. Discussion We concluded that an athlete’s negative thoughts play a pivotal role in predicting athletes’ stress-burnout relationship. Future study may examine how irrational cognition influences athletes’ motivation and psychological well-being.

[Factors influencing the sense of unintegration of thoughts in maintaining anger].

Science.gov (United States)

Endo, Hiroko; Yukawa, Shintaro

2013-12-01

Endo and Yukawa (2012) investigated the process of maintaining anger and demonstrated that a sense of unintegration of thoughts maintained anger by promoting recurrent thinking and avoidance behavior. Our present study examined how personality characteristics and situational factors affected the process of maintaining anger. Undergraduates (N=713) wrote about an anger episode, and completed questionnaires assessing their sense of unintegration of thoughts, recurrent thinking, avoidance behaviors, and maintaining anger. The questionnaires also assessed personality characteristics such as difficulty in identifying feelings, and situational factors such as the need for maintaining relationships, anger arousability, and meaning-making for the anger episode. The results of covariance structure analysis indicated that difficulties in identifying feelings and anger arousability contributed to maintaining anger by increasing the sense of unintegration of thoughts just after the episode. However, the need for maintaining relationships directly reduced the sense of unintegration of thoughts just after the episode, and indirectly decreased the present sense of unintegration of thoughts by meaning-making. Moreover, although recurrent thinking promoted the current sense of unintegration of thoughts, it also provided meaning.

The opening of energy markets to competition became effective to professionals on July 1, 2004. In 2010 this opening has entered into a mature phase. As soon as 2005, a barometer survey has been implemented to investigate the professional clients and to collect statistical data about their behaviour with regards to the opening of markets to competition. This document deals with the results of the sixth run of the professionals' barometer carried out from August 30 to September 10, 2010 by the LH2 institute. Among the 1502 surveyed entities, LH2 has questioned the decision-makers responsible for the electricity and natural gas contracts. The barometer aimed at answering the following questions: - what is the level of knowledge and information of professionals about markets opening and the existing regulation? - What perception of this opening do they have? (pros/cons, advantages/drawbacks); - what behaviour do they have in front of the opening of markets to competition? (approach with respect to information needs, knowledge about the offer, intention to change supplier, brakes/motivations in entering the open market). (J.S.)

The opening of energy markets to competition became effective to professionals on July 1, 2004. In 2008 this opening is entering into a mature phase. As soon as 2005, a barometer survey has been implemented to investigate the professional clients and to collect statistical data about their behaviour with regards to the opening of markets to competition. This document deals with the results of the fourth run of the professionals' barometer carried out from November 19 to December 2, 2008 by the LH2 institute. Among the 1501 surveyed entities, LH2 has questioned the decision-makers responsible for the electricity and natural gas contracts. The barometer aimed at answering the following questions: - what is the level of knowledge and information of professionals about markets opening and the existing regulation? - What perception of this opening do they have? (pros/cons, advantages/drawbacks); - what behaviour do they have in front of the opening of markets to competition? (approach with respect to information needs, knowledge about the offer, intention to change supplier, brakes/motivations in entering the open market). (J.S.)

Briñol, Pablo; Petty, Richard E; Belding, Jennifer

2017-06-01

Many objectification phenomena can be understood from a mind-body dualism perspective in which the more people focus on their bodies, the less they focus on their minds. Instead of viewing mind and body in opposition to each other, we advocate for a more reciprocal view in which mind and body work in conjunction. Consistent with an integrated mind-body approach, we begin our review by describing research on embodied persuasion revealing that focusing on our own body can reduce but also increase thinking (elaboration), as well as affecting the use of thoughts in forming evaluations (validation). Next, we extend our integrated view to a new domain and suggest that physical objects can influence thoughts and that one's thoughts can also be objectified. The first portion of this section focuses on research on enclothed cognition revealing that wearing physical objects can operate through the same processes of elaboration (increasing and decreasing thinking) and validation (increasing and decreasing thought usage) as the body. The second portion reveals that thoughts can be understood and treated as if they were physical objects affecting evaluative processes by influencing elaboration and validation processes. The final section provides some practical guidance relevant to campaigns designed to reduce the objectification of women and the infrahumanization of stigmatized groups. © 2017 The British Psychological Society.

A lack of cerebral lateralization in schizophrenia is within the normal variation in brain maturation but indicates late, slow maturation.

The planum temporale (PT) bias, PT leftward, PT symmetry, and PT rightward reversal and sidedness preference, consistent right-handedness, ambilaterality, and consistent left-handedness are placed on a continuum mirroring the normal variation in rate of brain maturation. Maturational rate declines as we pass from PT leftward bias and consistent right-handedness to PT reversal and consistent left-handedness. Concomitantly, we expect an increased prevalence of males due to their pubertal age being about 2 years later than that of females, and a shift in cognitive profile from higher verbal scores than performance scores on the WAIS to higher performance than verbal scores. Three disorders fulfilling the criteria of late CNS maturation apart from the corresponding cognitive profile were studied: infantile autism (IA), schizophrenia (S), and developmental dyslexia (DD). These disorders have in common deficits in cognition, perception, and somatomotor function. The deficits range from an arrest in brain development (which is evident in infancy superimposed on late maturation in IA) to overall delayed brain and somatic development in S (culminating in postpubertal psychotic episodes and persistent and generalized residual deficits). Finally, reading inability, problems in perception (vision and hearing) and in motor coordination, particularly between the two hemispheres, characterize DD. Enhancing brain maturation and the prevalence of 'normal' cerebral asymmetry--laterality is preferable if we want to reduce the risk of developing the above-mentioned disorders. It is suggested that in the past environmental challenges have favored early maturation, with its abundant neuronal population, arborization and excessive density of synapses and cerebral excitability which has powered evolution through the mechanism of natural selection. Early maturation is obtainable through optimal nutrition, including a satisfactory amount of marine fat (PUFA), before and during pregnancy and

Full Text Available Abstract Background Suicidal thought is a risk factor and a stage in the suicidal process from planning to attempting and dying by suicide. To date, studies on suicidal thought in the general population, especially in Asian communities, have been limited. Method The WHO SUPRE-MISS (the multisite intervention study on suicidal behaviours community survey questionnaire was filled in for 2,280 randomly selected residents of the DongDa district of Hanoi, Vietnam by means of face-to-face interviews. This multi-factor questionnaire includes such variables as sociodemographic information, suicidal thought and history of suicide attempts, physical health, alcohol consumption and medication. Results Prevalence rates for life time suicidal thoughts, suicide plans and suicide attempts were 8.9%, 1.1% and 0.4% respectively. Suicidal thoughts are associated with multiple characteristics, such as female gender, single/widowed/separated/divorced marital status, low income, lifestyle (use of alcohol, sedatives and pain relief medication, but not with low education or employment status. Having no religion and being a Buddhist appear to be protective factors for suicidal thought. The ratio of suicidal thoughts, suicide plans and suicide attempts on a lifetime basis is 22.3:2.8:1. Conclusion In Vietnam, as in Western and other Asian countries, suicidal thoughts are associated with similar negative psychosocial risk factors, lifestyle and emotional problems, which implies that suicide preventive measure developed elsewhere can be adjusted to Vietnamese condition. Understanding the unique and common risks in a culture may assist in prediction and control.

Chlorophyll fluorescence intensity can be used as seed maturity and quality evaluation indicator. Chlorophyll fluorescence intensity of seed coats is tested to judge the level of chlorophyll content in seeds, and further to judge the maturity and quality of seeds. This research developed a detection system of tomato seeds maturity based on chlorophyll fluorescence spectrum technology, the system included an excitation light source unit, a fluorescent signal acquisition unit and a data processing unit. The excitation light source unit consisted of two high power LEDs, two radiators and two constant current power supplies, and it was designed to excite chlorophyll fluorescence of tomato seeds. The fluorescent signal acquisition unit was made up of a fluorescence spectrometer, an optical fiber, an optical fiber scaffolds and a narrowband filter. The data processing unit mainly included a computer. Tomato fruits of green ripe stage, discoloration stage, firm ripe stage and full ripe stage were harvested, and their seeds were collected directly. In this research, the developed tomato seeds maturity testing system was used to collect fluorescence spectrums of tomato seeds of different maturities. Principal component analysis (PCA) method was utilized to reduce the dimension of spectral data and extract principal components, and PCA was combined with linear discriminant analysis (LDA) to establish discriminant model of tomato seeds maturity, the discriminant accuracy was greater than 90%. Research results show that using chlorophyll fluorescence spectrum technology is feasible for seeds maturity detection, and the developed tomato seeds maturity testing system has high detection accuracy.

Guidelines for assessing the knowledge management maturity of organizations

C. J. Kruger

2007-11-01

Full Text Available In a recent article Kruger and Snyman hypothesized that progressions in knowledge management maturity (from a strategic perspective are directly related to an increased ability to speed up the strategic cycle of imitation, consolidation and innovation. The arguments proposed, however, neglected to supply the reader with a practical toolkit or even a roadmap (a time-related matrix, or questionnaire to successfully measure succession in knowledge management maturity. This article builds on the previous one and proposes a questionnaire consisting of six sections, containing 101 descriptive questions, to enable organizations to test and assess their knowledge management maturity empirically. The development of an instrument to measure knowledge management maturity required adhering to a research design that combined theoretical propositions with practical experimentation. As a point of departure, a knowledge management maturity matrix consisting of seven maturity levels was formulated. All questions contained within the matrix were benchmarked against a survey questionnaire developed by the public management service of the OECD (PUMA and were also pre-tested and validated. This process of refinement led to the formulation of the Knowledge Management Maturity Questionnaire. To avoid any taint of this research being based only on theoretical propositions, the questionnaire was tested by 178 master students of the University of Pretoria, South Africa, in nine different industries. The proposed questionnaire provides a bridge between theoretical propositions and practical usability, not only enabling knowledge management practitioners to assess the level of knowledge management maturity reached successfully but, more importantly, also serving as a guideline to institutionalize further and future knowledge management endeavours.

Gender Diversity, Sexual Orientation, and Bone Health in the Maturing Dancer.

Brown, Derrick D

2017-12-01

Gender identity forms an important aspect of still developing youths. Gender is traditionally classified into two distinct categories, female and male. Transgender is a general term that describes individuals who self-identity as male, female, both, or neither (i.e., gender fluid) and do not match the assigned at-birth gender. Adolescent transgender individuals are currently a marginal population. There are limited demographics on youths, but as of 2014 an estimate of 1.4 million adults in the USA identified as transgender. It does seem, however, as more adults embrace their gender diversity and come out as transgender, in some cases opting for surgical reassignment, more adolescents and families are accepting their diversity. A growing body of research highlights transgender adolescents and their specific medical and mental health needs. This review seeks to underscore physiological phenomena relevant to trans-individuals, particularly in adolescents maturing into young adults, and disseminate this knowledge to dance, health, and education professionals.

Goldey, Katherine L; van Anders, Sari M

2012-12-01

Sexual stimuli increase testosterone (T) or cortisol (C) in males of a variety of species, including humans, and just thinking about sex increases T in women. We investigated whether sexual thoughts change T or C in men and whether hormone measures (baseline, post-activity, and changes) correlate with psychological sexual arousal. We used the Imagined Social Situation Exercise to assess how hormones respond to and correlate with sexual thoughts and arousal relative to three control conditions: neutral, stressful, and positive. A total of 99 men provided a baseline saliva sample, imagined and wrote about a sexual or control situation, and provided a second saliva sample 15 min later. Results indicated that, for participants in the sexual condition, higher baseline and post-activity C corresponded to larger increases in self- reported sexual and autonomic arousal. Although sexual thoughts increased sexual arousal, they did not change T or C compared to control conditions. Our results suggest that sexual thoughts are not sufficient to change T or C in men, but C may facilitate sexual arousal by directing energy towards a sexual situation.

Sequential Analysis of Global Gene Expression Profiles in Immature and In vitro Matured Bovine Oocytes: Potential Molecular Markers of Oocyte Maturation

2011-03-16

Abstract Background Without intensive selection, the majority of bovine oocytes submitted to in vitro embryo production (IVP) fail to develop to the blastocyst stage. This is attributed partly to their maturation status and competences. Using the Affymetrix GeneChip Bovine Genome Array, global mRNA expression analysis of immature (GV) and in vitro matured (IVM) bovine oocytes was carried out to characterize the transcriptome of bovine oocytes and then use a variety of approaches to determine whether the observed transcriptional changes during IVM was real or an artifact of the techniques used during analysis. Results 8489 transcripts were detected across the two oocyte groups, of which ~25.0% (2117 transcripts) were differentially expressed (p < 0.001); corresponding to 589 over-expressed and 1528 under-expressed transcripts in the IVM oocytes compared to their immature counterparts. Over expression of transcripts by IVM oocytes is particularly interesting, therefore, a variety of approaches were employed to determine whether the observed transcriptional changes during IVM were real or an artifact of the techniques used during analysis, including the analysis of transcript abundance in oocytes in vitro matured in the presence of α-amanitin. Subsets of the differentially expressed genes were also validated by quantitative real-time PCR (qPCR) and the gene expression data was classified according to gene ontology and pathway enrichment. Numerous cell cycle linked (CDC2, CDK5, CDK8, HSPA2, MAPK14, TXNL4B), molecular transport (STX5, STX17, SEC22A, SEC22B), and differentiation (NACA) related genes were found to be among the several over-expressed transcripts in GV oocytes compared to the matured counterparts, while ANXA1, PLAU, STC1and LUM were among the over-expressed genes after oocyte maturation. Conclusion Using sequential experiments, we have shown and confirmed transcriptional changes during oocyte maturation. This dataset provides a unique reference resource

Professional fishing, carried out from August to December 1996, uses FADs (Fish Attracting Devices and surrounding nets. 2087 juvenile specimens of dolphinfish from the Ionian and southern Tyrrhenian seas, the Strait of Sicily and the Balearic islands were sampled. A small number of adult fish (39, which are not usually caught in surrounding nets, was sampled in the swordfish long-line by-catch. The gonads of the young fish were analysed monthly to establish the stage of development of the ovaries or testes, during the first few months of life. The gonads of the adult fish, sampled in the months of June-September only, were all mature. The specimens caught between October and December presented maturity stage V in the case of the females and I in the case of the males, indicating the end of the reproductive period. The gonado-somatic index (GSI and condition factor (CF were calculated for both genders. The trend of the GSI confirms the presence of immature specimens as regards the juvenile fish; the low value of GSI was obtained for the adults, probably associated with the post-reproduction conditions found in the October-December period. Most of the gonads sampled during the months between August and December belonged to young specimens born in early summer. This is confirmed by the juvenile stages (FL 2.5 to 4.3 cm caught with plankton nets in the Strait of Messina area in July.

Full Text Available The aim of this study is to examine bullying in the workplace from the perspective of Australian Information Communication Technology (ICT professionals. The data collection for this project included conducting a quantitative survey with 2,315 participants and 43 qualitative interviews with members of Australian Computer Society (ACS. We found that 630 ICT professionals, or 27.23% of all survey respondents, identified workplace bullying as an ethical problem. The majority of survey respondents who selected bullying as an ethical issue were permanent full time employees (N= 413, 65.6%. A significant relationship was found between respondents identifying bullying as an ethical issue in the survey and their job classification (Deviance = 25.55, Df = 11, p=0.0076, suggesting that job classification, among other things, does predict respondents’ selection of bullying. Furthermore, our survey and interview findings indicate that the more mature respondents, as well as those in the managerial roles, have a greater concern about bullying.

The vast majority of germ cell tumors in the thorax arise at or near the thymus. We report a case of a 41-year-old man with mature teratoma of the posterior mediastinum. He was asymptomatic and was incidentally found to have a posterior mediastinal mass. Computed tomography was helpful in suggesting a diagnosis of mature teratoma by demonstrating the presence of fat and calcification. The differential diagnosis included neurogenic tumors, liposarcoma, and extramedullary hematopoiesis. (orig.)

Mature Oocyte Cryopreservation for Fertility Preservation.

Liang, Tina; Motan, Tarek

2016-01-01

In recent decades, advances in cancer treatment have led to a dramatic improvement in long term survival. This has led to an increasing focus on quality of life after surviving cancer treatment, with fertility being an important aspect. Given the known reproductive risks of cancer therapies, there has been a growing interest in the field of fertility preservation (also referred to as oncofertility). Mature oocyte cryopreservation is no longer considered experimental and has become a realistic option for reproductive aged women prior to undergoing cancer treatment. Additionally, as cryopreservation techniques improve, mature oocyte cryopreservation is increasing being marketed to healthy women without cancer wishing to delay child bearing, also termed "social egg freezing". This chapter provides a review of the current technology, use, and outcomes of mature oocyte cryopreservation. It also outlines the ethical debate surrounding social egg freezing and directions for future research in female fertility preservation.

Despite evidence of elevated risk factors for suicidal thoughts and behavior in youth with Tourette syndrome and chronic tic disorders (CTD), few studies have actually examined that relationship. This study documented the frequency and clinical correlates of suicidal thoughts and behaviors in a sample of children and adolescents with CTD (N = 196, range 6-18 years old). The content is solely the responsibility of the authors and does not necessarily represent the official views of the Centers for Disease Control. Youth and parents completed a battery of measures that assessed co-occurring psychiatric diagnoses, child emotional and behavioral symptoms, and impairment due to tics or co-occurring conditions. A structured diagnostic interview identified that 19 youths with CTD (9.7%) experienced suicidal thoughts and/or behaviors, which was elevated compared to 3 youths (3%) who experienced these thoughts in a community control sample (N = 100, range 6-18 years old, P = .03). For youth with CTD, suicidal thoughts and behaviors were frequently endorsed in the context of anger and frustration. The Child Behavior Checklist (CBCL) anxious/depressed, withdrawn, social problems, thought problems, and aggressive behavior subscales, as well as the total internalizing problems scale, were associated with the presence of suicidal thoughts and/or behaviors. Suicidal thoughts and/or behaviors were significantly associated with tic symptom severity; tic-related impairment; and obsessive-compulsive, depressive, anxiety, and attention-deficit/hyperactivity disorders' symptom severity. CBCL anxiety/depression scores mediated the relationship between tic severity and suicidal thoughts and behaviors. Findings suggest that about 1 in 10 youth with CTD experience suicidal thoughts and/or behaviors, which are associated with a more complex clinical presentation and often occur in the presence of anger and frustration. © 2015 Wiley Periodicals, Inc.

2015-01-01

Full Text Available The purpose of this paper is to empirically evaluate the relationship between the maturity of hotels’ information systems and their performance. This study uses customized models of information system (IS maturity and hotel performance measurement. Since we wanted to include the intangible aspects of performance, we opted for an adapted application of the Balanced Scorecard model. In the empirical part of the paper, fundamental constructs of the model are verified, while the individual items are further evaluated by employing discriminant analysis to distinguish hotels with relatively low and high performance levels. The findings demonstrate the existence of a significant and positive relationship between IS maturity and two dimensions of performance in the hospitality industry – process quality and guest relationships. The level of employee development and financial performance do not seem to be related to IS maturity. Although representative, the sample is relatively small, and the primary data were collected in a single country. The paper provides a framework of IS maturity items in the hospitality industry which seem to contribute to hotels’ business performances. As such, it can serve as a practical framework relevant for IT management in tourism and hospitality. The paper addresses a topic already discussed in a range of industries, although it does not seem to have been empirically evaluated by many studies of the tourism and hospitality industry. In addition, a new theoretical model of IT maturity in tourism and hospitality is proposed.

CT findings of overian teratomas : mature versus immature

1996-01-01

To differentiate mature and immature ovarian teratomas, using CT findings. The CT findings of ten mature ovarian teratomas (in one patient, bilateral) and ten which were immature were compared, using statistical analysis. Images were evaluated for size, margins, architecture, contents (mural nodules, fat, calcification), septa, local invasion and distant metastasis. These findings were compared with pathologic findings. Of the ten mature tumors, nine were well defined and predominantly cystic in internal architecture, and one was mixed. Mural nodules were found in six tumor, fat in all, distinct calcification in seven, and regular septa in three lesions. Of the ten immature humors, eight had irregular margins. Seven were predominantly solid in internal architecture and irregularly enhanced, two were mixed, and one was mainly cystic. Fat was detected in five lesions, indistinct scattered calcification in six, irregular septa in three, and local invasion of distant metastasis in four patients. Compared with mature ovarian teratomas, those that are immature tend to show CT findings of marginal irregularity, solid mass with irregular enhacement, scattered indistinct calcifications, septal irregularity, local invasion or distant metastasis. Our experience suggests that these findings may be helpful in differentiation of mature and immature ovarian teratomas

2013-01-01

Parenting behaviors and parent-infant emotional bonding during the early postpartum months play a critical role in infant development. However, the nature and progression of parental thoughts and their relationship with interactive behaviors have received less research. The current study investigated the trajectory of parental thoughts and behaviors among primiparous mothers ( n = 18) and fathers ( n = 15) and multiparous mothers ( n = 13) and fathers ( n = 13), which were measured at the first and third postpartum month. At the third postpartum month, the relationship between parental thoughts and parental interactive behaviors also was tested. Mothers and fathers showed high levels of preoccupations and caregiving thoughts during the first postpartum month that significantly declined by the third postpartum month. In contrast, positive thoughts about parenting and the infant increased over the same time interval. Mothers presented higher levels of preoccupations and positive thoughts than did fathers, and first-time parents reported more intense preoccupations than did experienced parents. Although maternal sensitivity was inversely related to maternal anxious thoughts, paternal sensitivity was predicted by higher levels of anxious as well as caregiving and positive thoughts.

Full Text Available Poetry of Momcilo Nastasijevic gives us undoubted motive to talk about him as a consistent religious poet, a poet of orthodox religious inspiration. He approached towards words as sanctity, he endeavoured to measure each word, reach it, and clean it from accumulated dust of everyday’s blather. His attitude towards poetical locution, his personal law of poetical perfection, represents, brought up to the last consequences, principles of symbolist poetics. He thought of words as magic of sound and rhythm and examines all the effects we can get from it. To him, poetry was identical to crucial and the purest flickering of what he called human soul. The thought of our poet come down to essence of his poetry: who has understood his poems, can be sure that will understand Nastasijevic as a poet.

Thought-evoking approaches in engineering problems

In creating the value-added product in not distant future, it is necessary and inevitable to establish a holistic and though-evoking approach to the engineering problem, which should be at least associated with the inter-disciplinary knowledge and thought processes across the whole engineering spheres. It is furthermore desirable to integrate it with trans-disciplinary aspects ranging from manufacturing culture, through liberal-arts engineering, and industrial sociology.   The thought-evoking approach can be exemplified and typified by representative engineering problems: unveiling essential features in ‘Tangential Force Ratio and Interface Pressure’, prototype development for ‘Bio-mimetic Needle’ and application of ‘Water-jet Machining to Artificial Hip Joint’, product innovation in ‘Heat Sink for Computer’, application of ‘Graph Theory’ to similarity evaluation of production systems, leverage among reciprocity attributes in ‘Industrial and Engineering Designs for Machine Enclosure’,...

Formal Thought Disorder and language impairment in schizophrenia

Directory of Open Access Journals (Sweden)

Marcia Radanovic

2013-01-01

Full Text Available Schizophrenia is a psychiatric illness in which disorders of thought content are a prominent feature. The disruption of normal flow of thought, or “Formal Thought Disorder” (FTD, has been traditionally assessed through the content and form of patients’ speech, and speech abnormalities in schizophrenia were considered as a by-product of the disruption in conceptual structures and associative processes related to psychosis. This view has been changed due to increasing evidence that language per se is impaired in schizophrenia, especially its semantic, discursive, and pragmatic aspects. Schizophrenia is currently considered by some authors as a “language related human specific disease” or “logopathy”, and the neuroanatomical and genetic correlates of the language impairment in these patients are under investigation. Such efforts may lead to a better understanding about the pathophysiology of this devastating mental disease. We present some current concepts related to FTD as opposed to primary neurolinguistic abnormalities in schizophrenia.

Language is a means of logical thinking rather than a way of communication. However, literary language in Rudaki's poetry has the best capacity to identify and reveal mental concepts through using aesthetics. The main question of this article is how Rudaki connected language to thought and what is his artistic creation? For this reason the researcher, after presenting and considering evidences, proves that Rudaki has used all characteristics of language and principals of creative language to connect literary language and thought together. The most prominent elements of Rudaki's thought and literary language are: using the most proper words in collocation, distinguishing the relationship of cause and effect and existence through literary language, asserting artistic fact, using imagination and principles of association of meanings, and entering poetical experience in language dominion (domain.

Many in dental education are unfamiliar with the professional life and thought of Dr. Alfred Owre, a distinguished though controversial dental educator in the early twentieth century. Owre served as dean of dentistry at both the University of Minnesota, 1905-27, and Columbia University, 1927-33. He was also a member of the Carnegie Foundation's commission that developed the report Dental Education in the United States and Canada, written by Dr. William J. Gies. Owre was a controversial leader due to his creative and original ideas that challenged dental education and the profession. His assessment and critique of the problems of dental education in his era can readily be applied to contemporary dental education and the profession, just as his vision for transformative change resonates with ideas that continue to be advocated by some individuals today. This article also documents his tumultuous relationship with Gies.

Full Text Available Approaches to the measurement and assessment of the company technological maturity level and management maturity apart, formulated in scientific researches and practical recommendations, significantly differ according to their purpose, content and depth of the factors analysis. Studies of the company technological maturity and possibility for implementing business processes and certain IT technologies have become more advanced in some degree. The general idea of forming a model of diagnostics of the management and technological maturity is based on the determination of prevailing company system influence components. Management techniques are a nucleus of the model, and the innovation level of management techniques is an energy impulse inciting to development. Basing on the analysis performed, the author created a concept of levels of the company management and technological maturity considering the main parameters of the company management and technological maturity. A composite algorithm was proposed for determining the level of managerial technological maturity (LMTM, end exposition of a complex of management techniques to ensure the company dynamic progress based on determining a level of the management and technological maturity. The advantages and disadvantages are determined by the methodology. The performed approbation has confirmed the approach validity and its usefulness. The approbation shows the reliability and unambiguity of interpreting results. To use it for bigger enterprises and corporations, it is not even necessary to change identification parameters.

The vast majority of germ cell tumors in the thorax arise at or near the thymus. We report a case of a 41-year-old man with mature teratoma of the posterior mediastinum. He was asymptomatic and was incidentally found to have a posterior mediastinal mass. Computed tomography was helpful in suggesting a diagnosis of mature teratoma by demonstrating the presence of fat and calcification. The differential diagnosis included neurogenic tumors, liposarcoma, and extramedullary hematopoiesis. (orig.) With 2 figs., 18 refs.

This study investigated the relationships between the stages of calcification of teeth and cervical vertebral maturation. The sample consisted of 295 subjects (129 male and 166 female), mean age 13.36 ± 2.65 (range 7-18) years. Dental age was evaluated from panoramic radiographs according to the method of Demirjian. Cervical vertebral maturation was determined on lateral cephalometric radiographs using cervical vertebrae maturation stages (CVS). For assessing the relationship between cervical vertebral and dental maturation, percentage distributions of the stages of calcification for each studied tooth were calculated. Only in the first CVS stage, boys and girls were of the same age. In all other stages (CVS 2-CVS 6) girls were by 0.98 (range 0.23-1.86) younger than boys. Gender differences in the mineralization pattern were also observed. It was found that dental maturation was finished earlier in female subjects. The highest correlation coefficient between dental and skeletal maturity was found for second premolars. Mineralization pattern of second premolars could be considered as a guideline for prediction of the pubertal growth spurt. Dental maturation stages might be clinically useful as a reliable indicator of facial growth.

To identify the relationship between professionalism and professional quality of life among oncology nurses working at tertiary hospitals in Korea. Oncology nurses are combined with core competencies and qualities required in cancer patient care. Professionalism that means compassion satisfaction and compassion fatigue is a main concept in problem-solving strategies as motivation. Their satisfaction is representative of professionalism and professional quality of life. However, little research has focused on professionalism and professional quality of life. A cross-sectional study with self-administered questionnaires. A total of 285 nurses from two tertiary hospitals were included. Data collection was undertaken using Korean version of professionalism scale derived from the Hall Professional Inventory Scale and professional quality of life. Data were analysed by spss 21.0 for Windows Program using t-test, anova, and multiple regression. The mean score of professionalism in oncology nurses was 77·98 ± 7·31. The mean professional quality of life score for compassion satisfaction, compassion fatigue and secondary traumatic stress was 33·84 ± 5·62, 28·38 ± 5·36 and 28·33 ± 5·48. Compassion satisfaction was affected by factors of professionalism with an explanatory power of 49·2%. Burnout and secondary traumatic stress were affected by factors of professionalism with an explanatory power of 39·3% and 4·8%. The higher the professionalism leads to the higher the compassion satisfaction, the lower the compassion fatigue. The relationship between professionalism and professional quality of life for a health work environment requires further investigation. Our study supports the idea that enhancing professionalism can increase professional quality of life. It is necessary to develop professionalism by recognised qualifications and applied rewards in advanced nursing organisational culture. Furthermore, compassion satisfaction is increased by

Conscious and unconscious thought in risky choice: testing the capacity principle and the appropriate weighting principle of unconscious thought theory.

Ashby, Nathaniel J S; Glöckner, Andreas; Dickert, Stephan

Daily we make decisions ranging from the mundane to the seemingly pivotal that shape our lives. Assuming rationality, all relevant information about one's options should be thoroughly examined in order to make the best choice. However, some findings suggest that under specific circumstances thinking too much has disadvantageous effects on decision quality and that it might be best to let the unconscious do the busy work. In three studies we test the capacity assumption and the appropriate weighting principle of Unconscious Thought Theory using a classic risky choice paradigm and including a "deliberation with information" condition. Although we replicate an advantage for unconscious thought (UT) over "deliberation without information," we find that "deliberation with information" equals or outperforms UT in risky choices. These results speak against the generality of the assumption that UT has a higher capacity for information integration and show that this capacity assumption does not hold in all domains. Furthermore, we show that "deliberate thought with information" leads to more differentiated knowledge compared to UT which speaks against the generality of the appropriate weighting assumption.

To describe and evaluate the current practice of in vitro maturation of oocytes for assisted reproduction. Review of the available and relevant literature regarding in vitro maturation of oocytes. In vitro maturation of human oocytes retrieved from antral ovarian follicles is an emerging procedure quickly being incorporated into the realm of assisted reproductive technologies. This new technology has several potential advantages over traditional controlled ovarian hyperstimulation for IVF, such as reduction of costs by minimizing gonadotropin and GnRH analogue use, elimination of ovarian hyperstimulation syndrome, and simplicity of protocol. In vitro maturation of oocytes for assisted reproduction in human beings still is undergoing refinement but currently is providing efficacy and safety outcome comparable to that of traditional IVF in recent selected studies. Implementing in vitro maturation into an established IVF practice is feasible and requires only a few simple adjustments. Crucial to the advancement and optimization of the technology is a better understanding of how to maximize immature oocyte developmental competence and endometrial receptivity.

Requirements are elicited step by step during the requirements engineering (RE) process. However, some types of requirements are elicited completely after the scheduled requirements elicitation process is finished. Such a situation is regarded as problematic situation. In our study, the difficulties of eliciting various kinds of requirements is observed by components. We refer to the components as observation targets (OTs) and introduce the word “Requirements maturation.” It means when and how requirements are elicited completely in the project. The requirements maturation is discussed on physical and logical OTs. OTs Viewed from a logical viewpoint are called logical OTs, e.g. quality requirements. The requirements of physical OTs, e.g., modules, components, subsystems, etc., includes functional and non-functional requirements. They are influenced by their requesters' environmental changes, as well as developers' technical changes. In order to infer the requirements maturation period of each OT, we need to know how much these factors influence the OTs' requirements maturation. According to the observation of actual past projects, we defined the PRINCE (Pre Requirements Intelligence Net Consideration and Evaluation) model. It aims to guide developers in their observation of the requirements maturation of OTs. We quantitatively analyzed the actual cases with their requirements elicitation process and extracted essential factors that influence the requirements maturation. The results of interviews of project managers are analyzed by WEKA, a data mining system, from which the decision tree was derived. This paper introduces the PRINCE model and the category of logical OTs to be observed. The decision tree that helps developers infer the maturation type of an OT is also described. We evaluate the tree through real projects and discuss its ability to infer the requirements maturation types.

Thinking about suicide is an indicator of suicide risk. Suicide rates are higher among doctors than in the population. The main aims of this study are to describe the changes in the lifetime prevalence of suicidal feelings from 2000 to 2010 and the possible predictors of serious suicidal thoughts in 2010 among Norwegian doctors. Differences in lifetime prevalence of suicidal feelings between Norwegian doctors in 2010 and German doctors in 2006 will be also described. Longitudinal and cross-sectional study based on questionnaire data from 2000 and 2010, including approximately 1,600 Norwegian doctors. In Germany, cross-sectional study based on questionnaire data from 2006 among a sample of 3,295 doctors. The main outcome measures were the lifetime prevalence of suicidal feelings (felt life was not worth living, wished own death, had thoughts of taking own life). The prevalences in 2000 and 2010 of ever had feelings of life not worth living were 48 (44 to 52) % and 45 (41 to 49) %, of ever wished own death 27 (23 to 30) % and 23 (20 to 26) %, and of ever had thoughts of taking own life 29 (16 to 33) % and 24 (21 to 27) %. Paired t-tests among those who responded both in 2000 and 2010 show significant reductions for felt life not worth living (t = -3.4; p = 0.001), wished own death (t = -3.1; p = 0.002) and had thoughts of taking own life (t = -3.5; p feelings. Suicidal feelings among Norwegian doctors decreased from 2000 to 2010. Individual and work-related factors may to certain explain these findings. Compared with other professionals in Norway and doctors in Germany, Norwegian doctors showed no higher risk of suicidal thoughts.

Study of Kerogen Maturity using Transmission Fourier Transform Infrared Spectroscopy (FTIR)

Science.gov (United States)

Dang, S. T.

2014-12-01

Maturity of kerogen in shale governs the productivity and generation hydrocarbon type. There are generally two accepted methods to measure kerogen maturity; one is the measurement of vitrinite reflectance, %Ro, and another is the measurement of Tmax through pyrolysis. However, each of these techniques has its own limits; vitrinite reflectance measurement cannot be applied to marine shale and pre-Silurian shales, which lack plant materials. Furthermore, %Ro, requires the isolation and identification of vitrinite macerals and statistical measurements of at least 50 macerals. Tmax measurement is questionable for mature and post-mature samples. In addition, there are questions involving the effects of solvents on Tmax determinations. Fourier Transmission Infrared Spectroscopy, FTIR, can be applied for both qualitative and quantitative assessment on organics maturity in shale. The technique does not require separating organic matter or identifying macerals. A CH2/CH3 index, RCH, calculated from FTIR spectra is more objective than other measurements. The index increases with maturity (both natural maturation and synthetic maturation through hydrous and dry pyrolysis). The new maturity index RCH can be calibrated to vitrinite reflectance which allows the definition of the following values for levels of maturity: 1) immature—RCH > 1.6±0.2; 2) oil window-- 1.6±0.2 1.3±0.3; 3) wet gas window--1.3±0.3 1.13±0.05; and 4) dry gas window RCH < 1.13±0.05.

Readiness for self-directed change in professional behaviours: factorial validation of the Self-Reflection and Insight Scale.

Roberts, Chris; Stark, Patsy

2008-11-01

Self-reflection, the practice of inspecting and evaluating one's own thoughts, feelings and behaviour, and insight, the ability to understand one's own thoughts, feelings and behaviour, are central to the self-regulation of behaviours. The Self-Reflection and Insight Scale (SRIS) measures three factors in the self-regulation cycle: need for reflection; engagement in reflection, and insight. We used structural equation modelling to undertake a confirmatory factor analysis of the SRIS. We re-specified our model to analyse all of the data to explain relationships between the SRIS, medical student characteristics, and responses to issues of teaching and learning in professionalism. The factorial validity of a modified SRIS showed all items loading significantly on their expected factors, with a good fit to the data. Each subscale had good internal reliability (> 0.8). There was a strong relationship between the need for reflection and engagement in reflection (r = 0.77). Insight was related to need for reflection (0.22) and age (0.21), but not to the process of engaging in reflection (0.06). Validation of the SRIS provides researchers with a new instrument with which to measure and investigate the processes of self-reflection and insight in the context of students' self-regulation of their professionalism. Insight is related to the motive or need for reflection, but the process of reflection does not lead to insight. Attending to feelings is an important and integral aspect of self-reflection and insight. Effective strategies are needed to develop students' insight as they reflect on their professionalism.

Brain mechanisms for loss of awareness of thought and movement

Abstract Loss or reduction of awareness is common in neuropsychiatric disorders and culturally influenced dissociative phenomena but the underlying brain mechanisms are poorly understood. fMRI was combined with suggestions for automatic writing in 18 healthy highly hypnotically suggestible individuals in a within-subjects design to determine whether clinical alterations in awareness of thought and movement can be experimentally modelled and studied independently of illness. Subjective ratings of control, ownership, and awareness of thought and movement, and fMRI data were collected following suggestions for thought insertion and alien control of writing movement, with and without loss of awareness. Subjective ratings confirmed that suggestions were effective. At the neural level, our main findings indicated that loss of awareness for both thought and movement during automatic writing was associated with reduced activation in a predominantly left-sided posterior cortical network including BA 7 (superior parietal lobule and precuneus), and posterior cingulate cortex, involved in self-related processing and awareness of the body in space. Reduced activity in posterior parietal cortices may underlie specific clinical and cultural alterations in awareness of thought and movement. Clinically, these findings may assist development of imaging assessments for loss of awareness of psychological origin, and interventions such as neurofeedback. PMID:28338742

Peters, Evyn M; Balbuena, Lloyd; Marwaha, Steven; Baetz, Marilyn; Bowen, Rudy

2016-12-01

Impulsivity, the tendency to act quickly without adequate planning or concern for consequences, is a commonly cited risk factor for suicidal thoughts and behaviour. There are many definitions of impulsivity and how it relates to suicidality is not well understood. Mood instability, which describes frequent fluctuations of mood over time, is a concept related to impulsivity that may help explain this relationship. The purpose of this study was to determine whether impulsivity could predict suicidal thoughts after controlling for mood instability. This study utilized longitudinal data from the 2000 Adult Psychiatric Morbidity Survey (N = 2,406). There was a time interval of 18 months between the two waves of the study. Trait impulsivity and mood instability were measured with the Structured Clinical Interview for DSM-IV Axis II Personality Disorders. Logistic regression analyses were used to evaluate baseline impulsivity and mood instability as predictors of future suicidal thoughts. Impulsivity significantly predicted the presence of suicidal thoughts, but this effect became non-significant with mood instability included in the same model. Impulsivity may be a redundant concept when predicting future suicidal thoughts if mood instability is considered. The significance is that research and therapy focusing on mood instability along with impulsivity may be useful in treating the suicidal patient. Mood instability and impulsivity both predict future suicidal thoughts. Impulsivity does not predict suicidal thoughts after controlling for mood instability. Assessing and treating mood instability could be important aspects of suicide prevention and risk management. © 2015 The British Psychological Society.

Quercetin it has been extensively studied by researchers on animals over the 35 years. It is a plant derived flavonoid from fruits and vegetables that has antioxidant action as a free radical scavenger. Immature porcine oocytes were untreated and treated with 5, 15, 25, 35 µg/ml quercetin during in vitro maturation. After then the mature oocytes were fertilized. It was observed that cumulus cell expansion of COCs cultured in maturation media supplemented with 5 µg/ml quercetin in grad 3 could be very significantly increased (p<0.001. In grad 4 could be significantly between different levels of quercetin (5 vs. 25, 5 vs. 35, p<0.001. The rates of embryos cultured in medium supplemented with different levels of quercetin did not presented significantly statistically different. The presence of 25 µg/ml quercetin in the maturation medium increased the percentage of embryos in the morula stage compared with the control. In the morula stage all the concentrations of quercetin resulted percentages increased to control. This results shows that quercetin added during in vitro maturation has a positive effect on future embryos development.

As Technologies for Nucleotide Therapeutics Mature, Products Emerge.

Beierlein, Jennifer M; McNamee, Laura M; Ledley, Fred D

2017-12-15

The long path from initial research on oligonucleotide therapies to approval of antisense products is not unfamiliar. This lag resembles those encountered with monoclonal antibodies, gene therapies, and many biological targets and is consistent with studies of innovation showing that technology maturation is a critical determinant of product success. We previously described an analytical model for the maturation of biomedical research, demonstrating that the efficiency of targeted and biological development is connected to metrics of technology growth. The present work applies this model to characterize the advance of oligonucleotide therapeutics. We show that recent oligonucleotide product approvals incorporate technologies and targets that are past the established point of technology growth, as do most of the oligonucleotide products currently in phase 3. Less mature oligonucleotide technologies, such as miRNAs and some novel gene targets, have not passed the established point and have not yielded products. This analysis shows that oligonucleotide product development has followed largely predictable patterns of innovation. While technology maturation alone does not ensure success, these data show that many oligonucleotide technologies are sufficiently mature to be considered part of the arsenal for therapeutic development. These results demonstrate the importance of technology assessment in strategic management of biomedical technologies. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights reserved.

Wilcox, Holly C.; Schonfeld, Irvin Sam; Davies, Mark; Hicks, Roger C.; Turner, J. Blake; Shaffer, David

2009-01-01

Objectives. We sought to determine the degree of overlap between students identified through school-based suicide screening and those thought to be at risk by school administrative and clinical professionals. Methods. Students from 7 high schools in the New York metropolitan area completed the Columbia Suicide Screen; 489 of the 1729 students screened had positive results. The clinical status of 641 students (73% of those who had screened positive and 23% of those who had screened negative) was assessed with modules from the Diagnostic Interview Schedule for Children. School professionals nominated by their principal and unaware of students' screening and diagnostic status were asked to indicate whether they were concerned about the emotional well-being of each participating student. Results. Approximately 34% of students with significant mental health problems were identified only through screening, 13.0% were identified only by school professionals, 34.9% were identified both through screening and by school professionals, and 18.3% were identified neither through screening nor by school professionals. The corresponding percentages among students without mental health problems were 9.1%, 24.0%, 5.5%, and 61.3%. Conclusions. School-based screening can identify suicidal and emotionally troubled students not recognized by school professionals. PMID:19059865

Patients with cardiovascular risk factors can reduce their risk of cardiovascular disease by increasing their physical activity and their physical fitness. According to the guidelines for cardiovascular risk management, health professionals should encourage their patients to engage in physical activity. In this paper, we provide insight regarding the systematic development of a Web-based intervention for both health professionals and patients with cardiovascular risk factors using the development method Intervention Mapping. The different steps of Intervention Mapping are described to open up the "black box" of Web-based intervention development and to support future Web-based intervention development. The development of the Professional and Patient Intention and Behavior Intervention (PIB2 intervention) was initiated with a needs assessment for both health professionals (ie, physiotherapy and nursing) and their patients. We formulated performance and change objectives and, subsequently, theory- and evidence-based intervention methods and strategies were selected that were thought to affect the intention and behavior of health professionals and patients. The rationale of the intervention was based on different behavioral change methods that allowed us to describe the scope and sequence of the intervention and produced the Web-based intervention components. The Web-based intervention consisted of 5 modules, including individualized messages and self-completion forms, and charts and tables. The systematic and planned development of the PIB2 intervention resulted in an Internet-delivered behavior change intervention. The intervention was not developed as a substitute for face-to-face contact between professionals and patients, but as an application to complement and optimize health services. The focus of the Web-based intervention was to extend professional behavior of health care professionals, as well as to improve the risk-reduction behavior of patients with

Results The systematic and planned development of the PIB2 intervention resulted in an Internet-delivered behavior change intervention. The intervention was not developed as a substitute for face-to-face contact between professionals and patients, but as an application to complement and optimize health services. The focus of the Web-based intervention was to extend professional behavior of health care professionals, as well as to improve the risk

A study was conducted to examine the role of concrete and formal operations in a young and old population. In addition, the present study explored the relation between operational thought and Cattell's concept of fluid and crystallized intelligence, as well as the role of differential living arrangements in maintaining operational thought. Eighty females from three age groups (18-20 years, 60-70 years and 70-80 years of age) were tested on a series of Piagetian tasks and indices of fluid and crystallized intelligence. The findings supported the notion that age-related performance differences occur in the area of formal operational thought prior to the time they occur in concrete operational thought. Except for the young sample, the operational tasks were found to be unrelated to fluid intelligence at the age levels represented in this study. Living independently as opposed to living in an old age home did not appear to be a significant factor in maintaining operational thought. Discussion focused on the necessity of identifying those factors which influence the developmental course of formal operational thought across the life span.

The I-Tribe Community Pharmacy Practice Model: professional pharmacy unshackled.

Alston, Greg L; Waitzman, Jennifer A

2013-01-01

To describe a mechanism by which pharmacists could create a disruptive innovation to provide professional primary care services via a Web-based delivery model. Several obstacles have prevented pharmacists from using available technology to develop business models that capitalize on their clinical skills in primary care. Community practice has experienced multiple sustaining innovations that have improved dispensing productivity but have not stimulated sufficient demand for pharmacy services to disrupt the marketplace and provide new opportunities for pharmacists. Pharmacists are in a unique position to bridge the gap between demand for basic primary medical care and access to a competent medical professional. Building on the historic strengths of community pharmacy practice, modern pharmacists could provide a disruptive innovation in the marketplace for primary care by taking advantage of new technology and implementing the I-Tribe Community Pharmacy Practice Model (I-Tribe). This model would directly connect pharmacists to patients through an interactive, secure Web presence that would liberate the relationship from geographic restrictions. The I-Tribe is a disruptive innovation that could become the foundation for a vibrant market in pharmacist professional service offerings. The I-Tribe model could benefit society by expanding access to primary medical care while simultaneously providing a new source of revenue for community practice pharmacists. Entrepreneurial innovation through I-Tribe pharmacy would free pharmacists to become the care providers envisioned by the profession's thought leaders.

Morphological and functional maturation of Leydig cells: from rodent models to primates.

Teerds, Katja J; Huhtaniemi, Ilpo T

2015-01-01

the FLC population, there is consensus about the essential role of gonadotrophins in testosterone production. Like the FLC population, adult Leydig cells (ALC) in rodents arise from stem cells, which have their origin in the fetal testis. In contrast, in primates the ALC population is thought to originate from FLC, which undergo several cycles of regression and redifferentiation before giving rise to the mature ALC population, as well as from differentiation of stem cells/precursor cells. Despite this difference in origin, both in primates and rodents the formation of the mature and functionally active ALC population is critically dependent on the pituitary gonadotrophin, LH. From studies on rodents considerable knowledge has emerged on factors that are involved besides LH in the regulation of this developmental process. Whether the same factors also play a role in the development of the mature primate LC population awaits further investigation. Distinct populations of LC develop along the life span of males, including fetal, neonatal (primates) and ALC. Despite differences in the LC lineages of rodents and primates, the end product is a mature population of LC with the main function to provide androgens necessary for the maintenance of spermatogenesis and extra-gonadal androgen actions. © The Author 2015.

Towards Professionalism in Music: Self-assessed Learning Strategies of Conservatory Music Students

Directory of Open Access Journals (Sweden)

Esa Virkkula

2017-09-01

Full Text Available One of the current spearhead projects in Finnish education is learning to learn. Learning strategies have been examined from a variety of perspectives. They are policies that either promote or hinder learning. They are any behaviours or thoughts that facilitate encoding in such a way that knowledge integration and retrieval are enhanced. Strategies can be practiced and learnt. Direct and indirect learning strategies formed the model of defining music students’ self-assessed learning habits in this research. The strategies dealt with here are memory, cognitive, compensation, metacognitive, affective and social strategies. Critical thinking strategies as well as deep and surface learning strategies were also observed. In this paper, a theoretical background and methodological solutions will first be presented. A significant finding comes from cross-professional collaboration of students, teachers, and professionals during the research period: it enhanced the use of strategies. Another finding, the profitable use of the workshop method, can be adopted by other fields of learning and make processes flexible and fruitful.

Foam-Test by Clements is a valuable method for determining the foetus maturity of lungs. We introduce this test along with other parameters for the maturity-diagnosis since one year. In 15% result, the Foam-Test was not applicable because of blood, or meconic amniotic fluid, other wise wrong negative and in 0% wrong positive results. By unmatured child, there was doubtable results with Foam-Test. Since it is important to determine the early delivery of unmatured children, particularly the case of foetus maturity of lungs must be exact, we therefore decided to use the Lecithin/Sphingomyelinquotients in some cases. The results of Lecithin/Sphingomyelinquotient in unmatured children are almost with the approximated date under two. From this, one must deduce from these children, that the intrauterine unmatured lungs lately took place.

2016-10-01

Many new athletic trainers (ATs) obtain graduate-assistant (GA) positions to gain more experience and professional development while being mentored by a veteran AT; however, GA ATs' perceptions of the supervisor's role in professional development are unknown. To explore the supervisor's role in the professional development of GAs in the collegiate setting. Qualitative study. Phone interviews. A total of 19 collegiate GAs (15 women, 4 men; average age = 23 ± 0.15 years; National Collegiate Athletic Association Division I = 13, II = 3, III = 2; National Association of Intercollegiate Athletics = 2; postprofessional athletic training program = 5). Data were collected via phone interviews and transcribed verbatim. Interviews were conducted until data saturation occurred. Data were analyzed through phenomenologic reduction. Trustworthiness was established via member checks and peer review. Three themes emerged: (1) GAs' expectations of supervisors, (2) professional development, and (3) mentoring and support. Participants expected their supervisors to provide mentorship, support, and feedback to help them improve their athletic training skills, but they also realized supervisors were busy with patient care responsibilities. Most participants felt their supervisors were available, but others believed their supervisors were too busy to provide support and feedback. Participants felt their supervisors provided professional development by teaching them new skills and socializing them into the profession. Furthermore, they thought their supervisors provided mentorship professionally, personally, and clinically. Supervisors supported the participants by standing behind them in clinical decisions and having open-door policies. The graduate assistantship allows new ATs to gain experience while pursuing professional development, mentorship, and support from a supervisor. The extent of development is highly dependent on the supervisor, but most supervisors mentor GAs. When

Full Text Available In the pineapple sector of Benin, poor fruit quality prevents pineapple producers to enter the European market. We investigated effects of common cultural practices, flowering and maturity synchronisation, (1 to quantify the trade-offs of flowering and maturity synchronisation for pineapple quality and the proportion of fruits exportable to European markets, and (2 to determine the effect of harvesting practice on quality attributes. Four on-farm experiments were conducted during three years using cultivars Sugarloaf and Smooth Cayenne. A split-split plot design was used in each experiment, with flowering induction practice as main factor (artificial or natural flowering induction, maturity induction practice as split factor (artificial or natural maturity induction and harvesting practice as the split-split factor (farmers' harvest practice or individual fruit harvesting at optimum maturity. Artificial flowering induction gave fruits with lower infructescence weight, higher ratio crown: infructescence length, and a lower proportion of fruits exportable to European markets than natural flowering induction. The costs of the improvements by natural flowering induction were huge: the longer durations from planting to flowering induction and harvesting, the higher number of harvestings of the fruits increasing the labour cost and the lower proportion of plants producing fruits compared with crops from artificially flowering-induced plants. Artificial maturity induction decreased the total soluble solids concentration in the fruits compared with natural maturity induction thus decreasing the proportion of fruits exportable to European markets, at a benefit of only a slightly shorter time from flowering induction to harvesting. Harvesting individual fruits at optimum maturity gave fruits with higher total soluble solids in naturally maturity induced fruits compared with the farmers' harvest practice. Given the huge costs of natural flowering induction

On social death: ostracism and the accessibility of death thoughts.

Steele, Caroline; Kidd, David C; Castano, Emanuele

2015-01-01

Being rejected, excluded, or simply ignored is a painful experience. Ostracism researchers have shown its powerful negative consequences (Williams, 2007), and sociologists have referred to such experiences as social death (Bauman, 1992). Is this is just a metaphor or does being ostracized make death more salient in people's minds? An experiment was conducted in which participants experienced ostracism or inclusion using the Cyberball manipulation, and the accessibility of death-related thoughts was measured via a word-stem completion puzzle. Results showed enhanced death-thought accessibility in the ostracism condition, as well as a negative effect of dispositional self-esteem on the accessibility of death-related thoughts.

Tomatoes (Lycopersicon esculentum L., var. Monte Carlo) have been ..gamma..-irradiated (100 to 400 krad) and left to ripen to consuming ripeness. The results revealed that in fruits irradiated with 100, 200 and 300 krad at mature-green, 48 hours after harvesting and at greenish yellow stages of maturity, 24 hours after harvesting, the levels of ascorbic acid were accounted to 62, 51, 27% and 84, 59, 34% of control samples respectively. In fruits irradiated with 200 krad at mature-green stage and 48 hours after harvesting and in fruits irradiated with 400 krad at greenish yellow stage and 48 hours after harvesting, the levels of lycopene were 279 and 246% of that of control samples; while the lowest levels of lycopene were in fruits irradiated with 400 krad and at mature-green and greenish yellow stages and 48 hours after harvesting where lycopene accounted to 11 and 24% respectively when compared to control samples. On the other hand, radiation had no significant effect on PH, titrable acidity and deg Brix of tomatoes.

SUMMARY This study examines in detail - i) the magnitude, nature and severity of thought disorder in schizophrenia, ii) the correlations between type and severity of thought disorder with socio-demographic and clinical variables, and iii) differences between different subtypes of schizophrenia. Forty five schizophrenics (Research Diagnostic Criteria) were assessed by ‘live’ interview as well as tape recorded interviews. Instruments used for assessment were (a) Scale for assessment of Thought, Language and Communication (Andreasen 1978), (b) Brief Psychiatric Rating Scale (Overall & Gorham 1962), (c) Mini Mental State (Folstein 1975), and (d) Clinical and demographic data recording proforma. The Schizophrenic patients were subdivided as (i) Acute and chronic (R.D.C.), (ii) Paranoid and non-paranoid; and (iii) Negative, positive, mixed (Andreasen's criteria) and intragroup and intergroup differences were computed. Poverty of speech, tangentiality, derailment, loss of goal, perseveration were found to be the commonest thought disorders. Positive and negative thought disorders were seen in equiproportion in both positive and negative schizophrenics. Significant differences were noted between thought disorders and education as well as habitat. Rural patients more often had negative formal thought disorders. Literates had more often clanging, neologism, circumstantiality and echolalia. This study provides ample information on the nature of thought disorder in Indian schizophrenic subjects. PMID:21927321

Thought Experiments of Economic Surplus: Science and Economy in Ernst Mach's Epistemology. Thought experiments are an important element in Ernst Mach's epistemology: They facilitate amplifying our knowledge by experimenting with thoughts; they thus exceed the empirical experience and suspend the quest for immediate utility. In an economical perspective, Mach suggested that thought experiments depended on the production of an economic surplus based on the division of labor relieving the struggle for survival of the individual. Thus, as frequently emphasized, in Mach's epistemology, not only the 'economy of thought' is an important feature; instead, also the socioeconomic conditions of science play a decisive role. The paper discusses the mental and social economic aspects of experimental thinking in Mach's epistemology and examines those within the contemporary evolutionary, physiological, and economic contexts. © 2015 WILEY-VCH Verlag GmbH & Co.

Thought suppression has spurred extensive research in clinical and preclinical fields, particularly with regard to the paradoxical aspects of this behavior. However, the involvement of the brain's inhibitory system in the dynamics underlying the continuous effort to suppress thoughts has yet to be clarified. This study aims to provide a unified perspective for the volitional suppression of internal events incorporating the current understanding of the brain's inhibitory system. Twenty healthy volunteers underwent functional magnetic resonance imaging while they performed thought suppression blocks alternating with visual imagery blocks. The whole dataset was decomposed by group-independent component analysis into 30 components. After discarding noise components, the 20 valid components were subjected to further analysis of their temporal properties including task-relatedness and between-component residual correlation. Combining a long task period and a data-driven approach, we observed a right-side-dominant, lateral frontoparietal network to be strongly suppression related. This network exhibited increased fluctuation during suppression, which is compatible with the well-known difficulty of suppression maintenance. Between-network correlation provided further insight into the coordinated engagement of the executive control and dorsal attention networks, as well as the reciprocal activation of imagery-related components, thus revealing neural substrates associated with the rivalry between intrusive thoughts and the suppression process.

2013-03-01

Full Text Available In the dif?cult conditions of the contemporary society which are far from being favorable to maintain one’s emotional and physical health the problem of development and achievement of emotional maturity as a factor of the well-being is getting more signi?cant. Based on the theoretical concepts of different scientists who de?ned the construct of emotional maturity three groups of psychological methods for assessing emotional maturity are analyzed. The ?rst group includes the methods that are used to assess emotional maturity explicitly and have a theoretical or empirical veri?cation. The second group includes the methods that are intended to assess emotional maturity as a separate scale complimented by other scales, related to evaluating other aspects of emotionality in  the  structure  of  the  personality.  The  third  group  includes  the  methods  in  which  emotional maturity is mentioned in the description of other psychic phenomena, or in the interpretation of certain factors (scales. Psychodiagnostic methods studying different parameters depending on the theoretical concepts of the authors about the structure and content of the emotional maturity of the personality make references to concepts of emotional development, consciousness, cognitive and volitional capacities of the personality and the coping strategies the individual prefer to use. The problem of developing valid and reliable psychodiagnostic methods of studying emotional maturity of the adult personality as a holistic phenomenon still awaits attention and retains its signi?cance.

Considerable variations in the development stage among patients of the same chronological age have led to introduce the concept of the developmental age based on the maturation of different organs such as cervical vertebrae or teeth. The purpose of this study was to investigate the correlation between the stages of tooth calcification and the cervical vertebral maturation in Iranian females. Four hundred females (age range, 8 to 14 years) participated in the study. To determine the dental maturational stage, calcification of the mandibular teeth except for third molars were rated according to the method suggested by Demirjian et al. To evaluate the stage of skeletal maturation, cervical vertebral morphologic changes were assessed on lateral cephalometric radiographs according to the method explained by Baccetti et al. Correlations between bone maturation and teeth calcification were showed by Spearman's correlation and Kendall's tau-b coefficients. The relevant associations were investigated by ordinal logistic regression models. Correlations between the two stages were observed in the first and second premolars, canine and central incisors. All these correlations were significant. The association between cervical vertebral maturation and tooth calcification was greatest in the lateral incisor (odds ratio (OR) = 11, 95% confidence interval (CI): 6.6-18.3). However, considering the 95% CI for OR, no significant difference was detected among the second molar, first molar and lateral incisor. The relationship between calcification of teeth and maturation of cervical bones was significant. Bone maturation can be predicted by using teeth calcification stages, especially in the second molar, first molar and lateral incisor.

Covering both the history of mathematics and of philosophy, Descartes's Mathematical Thought reconstructs the intellectual career of Descartes most comprehensively and originally in a global perspective including the history of early modern China and Japan. Especially, it shows what the concept of "mathesis universalis" meant before and during the period of Descartes and how it influenced the young Descartes. In fact, it was the most fundamental mathematical discipline during the seventeenth century, and for Descartes a key notion which may have led to his novel mathematics of algebraic analysis.

1998-01-01

A technical maturity assessment method was performed by systems engineers in collaboration with an advisory panel composed of team members from different Department of Energy sites and from different engineering and science disciplines. Various stabilization technologies were assessed annually as to their relative maturity and availability for use in stabilizing nuclear materials. After three years of assessments, several of the technologies are now components of operational systems. A regression analysis of the historical assessments was performed, and it was concluded that the numerical technical maturity score produced by a team of experts can provide a powerful predictor of the time remaining until the operational application of technologies

Are professional drivers less sleepy than non-professional drivers?

Science.gov (United States)

Anund, Anna; Ahlström, Christer; Fors, Carina; Åkerstedt, Torbjörn

2018-01-01

Objective It is generally believed that professional drivers can manage quite severe fatigue before routine driving performance is affected. In addition, there are results indicating that professional drivers can adapt to prolonged night shifts and may be able to learn to drive without decreased performance under high levels of sleepiness. However, very little research has been conducted to compare professionals and non-professionals when controlling for time driven and time of day. Method The aim of this study was to use a driving simulator to investigate whether professional drivers are more resistant to sleep deprivation than non-professional drivers. Differences in the development of sleepiness (self-reported, physiological and behavioral) during driving was investigated in 11 young professional and 15 non-professional drivers. Results Professional drivers self-reported significantly lower sleepiness while driving a simulator than non-professional drivers. In contradiction, they showed longer blink durations and more line crossings, both of which are indicators of sleepiness. They also drove faster. The reason for the discrepancy in the relation between the different sleepiness indicators for the two groups could be due to more experience to sleepiness among the professional drivers or possibly to the faster speed, which might unconsciously have been used by the professionals to try to counteract sleepiness. Conclusion Professional drivers self-reported significantly lower sleepiness while driving a simulator than non-professional drivers. However, they showed longer blink durations and more line crossings, both of which are indicators of sleepiness, and they drove faster.

Full Text Available Love is a basic subject of Islamic mysticism. It is apparently the hallmark of Eynolghozat's thought as well. Hence, Mystics pronounce him as "Sheikh-al-Asheghin", "Sultan-al-oshshagh", and so on. Eynalghozat considers love as a common faith between God, human beings, and the whole universe by which enmity changes to friendship. He also considers love as a perfect leader who guides the lovers through the way ending to the eminent God. In his opinion, Love which can never be spoken of except by symbolic language is of three main types Great Love, e, middle love, and lower love. Like other mystics figurative (platonic love id of considerable importance for him. However, the first and second types of love -mentioned above- are much more prevalent in his works. In this article, the writer tries to supply a brief definition of love in Eynolghozat's opinion, as well as a comparison of his thoughts with his master that is, Ahmad Ghazali.

Non-matured arteriovenous fistulae for haemodialysis: diagnosis, endovascular and surgical treatment

Directory of Open Access Journals (Sweden)

Marko Malovrh

2010-04-01

Full Text Available Non-maturation is a feature of autologous vascular access. The autologous arteriovenous fistula needs time to mature and for the vein to enlarge to a size where it can be needled for dialysis. A fistula that fails early is one that either never develops adequately to support dialysis or fails within the first three months of its use. Two variables are required for fistula maturation. Firstly, the fistula should have adequate blood flow to support dialysis and secondly, it should have enough size to allow for successful repetitive cannulation. Three main reasons for maturation failure are: arterial and venous problems and the presence of accessory veins. Early diagnostics and intervention for fistula maturation minimizes catheter use and its associated complications. The identification of immature fistulae is relatively simple. Physical examination has been highlighted to be a valuable tool in assessing fistula. Any fistula that fails to mature adequately and demonstrates abnormal physical findings should be studied aggressively. Ultrasonography can successfully identify candidates who fail to meet the recently developed criteria for immature fistulae. In recent years, digital subtraction angiography and contrast-enhanced magnetic resonance angiography has been introduced for assessment of dysfunctional haemodialysis conduits, including immature fistulae. A great majority of non-matured fistulae can be successfully salvaged using percutaneous techniques. In addition to endovascular techniques, surgical intervention can also be an option. This paper reviews the process of fistula maturation and presents information regarding how to obtain a mature fistula.

2018-01-01

Full Text Available Glamorous and stylish, perfume is an evocative product that provokes a stimulus of the senses. It is suggested that the basis for consumer choice for this product should be based on olfactory preference, however the process related decision-making has been shown to be more complex. The mature consumer purchase decision making in this product category is often associated with long standing, established, luxury fragrance brands. In addition, at the frontline of the perfume sales process are fragrance consultants, who possess invaluable information on consumer involvement with perfume products and brands. Hence, this paper investigates CBR (consumer brand relationship and the subsequent perfume purchase behaviour of mature female consumers from a dual (industry and consumer perspective. Results indicate that important perceptual differences related to brand relationships with perfume exist between fragrance consultants and experts on one hand and consumers on the other. This research promotes a deeper understanding of current consumer approach and issues surrounding female mature purchasing behaviour for this unique category of product, and complements the growing body of literature related to luxury brands.

Towards an energy management maturity model

International Nuclear Information System (INIS)

Antunes, Pedro; Carreira, Paulo; Mira da Silva, Miguel

2014-01-01

Energy management is becoming a priority as organizations strive to reduce energy costs, conform to regulatory requirements, and improve their corporate image. Despite the upsurge of interest in energy management standards, a gap persists between energy management literature and current implementation practices. This gap can be traced to the lack of an incremental improvement roadmap. In this paper we propose an Energy Management Maturity Model that can be used to guide organizations in their energy management implementation efforts to incrementally achieve compliance with energy management standards such as ISO 50001. The proposed maturity model is inspired on the Plan-Do-Check-Act cycle approach for continual improvement, and covers well-understood fundamental energy management activities common across energy management texts. The completeness of our proposal is then evaluated by establishing an ontology mapping against ISO 50001. - Highlights: • Real-world energy management activities are not aligned with the literature. • An Energy Management Maturity Model is proposed to overcome this alignment gap. • The completeness and relevance of proposed model are validated

Spermatozoa maturation, a process required for spermatozoa to acquire progressive motility and the ability to fertilize ova, primarily occurs in the caput and corpus of the epididymis. Despite considerable efforts, the factor(s) promoting epididymal sperm maturation remains unclear. Recently, WNT signaling has been implicated in epididymal sperm maturation. To further investigate WNT signaling function in epididymal sperm maturation, we generated Wntless conditional knockout mice (Wls cKO), Wls flox/flox ; Lcn5-Cre. In these mice, WNTLESS (WLS), a conserved membrane protein required for all WNT protein secretion, was specifically disrupted in the principal cells of the caput epididymidis. Immunoblot analysis showed that WLS was significantly reduced in the caput epididymidis of Wls cKO mice. In the caput epididymidis of Wls cKO mice, WNT 10A and WNT 2b, which are typically secreted by the principal cells of the caput epididymis, were not secreted. Interestingly, sperm motility analysis showed that the WLS deficiency in the caput epididymidis had no effect on sperm motility. Moreover, fertility tests showed that Wls cKO male mice had normal fertility. These results indicate that the disruption of WLS in principal cells of the caput epididymidis inhibits WNT protein secretion but has no effect on sperm motility and male fertility, suggesting that WNT signaling in the caput epididymidis may be dispensable for epididymal sperm maturation in mice.

Full Text Available This study aims to evaluate the evolution of the maturation of the “Chardonnay” grape variety for the preparation of juices and its adequacy to the current legislation. Grapes from the 2015 harvest from São Lourenço do Sul-RS were used. The experimental design was completely randomized in a factorial design, with the treatment factor being the maturation stages. The physicochemical analysis of titratable acidity, soluble solids, relative density, total sugar, alcohol content, volatile acidity and SS/TA ratio were carried out in EPAGRI – Agricultural Research and Rural Extension Company of Santa Catarina, in the Videira Experimental Station (Videira SC/Brazil. Statistical analysis of the maturation stages was given by linear regression models. When comparing the maturation points of 17∘Brix and 19∘Brix to 15∘Brix, volatile acidity and alcohol content did not fit to the model, while the other tested variables fit properly. Elaborated juices had a decrease in titratable acidity and percentage increments for soluble solids, SS/TA ratio and total sugars for the harvest points at 17 and 19∘Brix. For 15∘Brix and 17∘Brix, nonconformity was observed with the identity and quality standards in relation to soluble solids and SS/TA ratio and relative density. At maturation point 19∘Brix all variables were found to be consistent.

The goal setting regime imposed by the UK safety regulator has important implications for an organisation's ability to manage health and safety related risks. Existing approaches to safety assurance based on risk analysis and formal safety assessments are increasingly considered unlikely to create the step change improvement in safety to which the offshore industry aspires and alternative approaches are being considered. One approach, which addresses the important issue of organisational behaviour and which can be applied at a very early stage of design, is the capability maturity model (CMM). The paper describes the development of a design safety capability maturity model, outlining the key processes considered necessary to safety achievement, definition of maturity levels and scoring methods. The paper discusses how CMM is related to regulatory mechanisms and risk based decision making together with the potential of CMM to environmental risk management.

Hong Kong Liberals Are WEIRD: Analytic Thought Increases Support for Liberal Policies.

This study tests whether liberals and conservatives within the same society think as if they were from different cultures. I tested this by measuring the cultural thought style of social liberals and conservatives in Hong Kong (Study 1). Liberals tended to think more analytically (more "WEIRD"), and conservatives tended to think more holistically (more common in East Asia). In Study 2, I trained people to think analytically or holistically before they read articles on political issues. Analytic thought caused people to form more liberal opinions, and holistic thought caused people to form more conservative opinions. The thought training affected participants' responses to a social issue, but not an economic issue or whether they identified as liberal or conservative. This study replicates a previous U.S. finding in an East Asian culture and a different political environment, suggesting that the link between politics and thought style extends beyond the United States.

Explore and transform dialogic-reflexive learning processes oriented to self-care, capacitation, empowerment and health promotion for "mature-adult" collective. Participative action research on a qualitative and sociocritic approach. Data generation methods are SITE: Field work focuses on the development of the educational program "Care is in your hands" that takes place in two villages (Primary Care. Comarca Araba). Through a theoretical sampling involved people who are in a "mature-adult" life stage and three nurses with extensive experience in development health education programs. Participant observation where health education sessions are recorded in video and group reflection on action. To triangulate the data, have been made in-depth interviews with 4 participants. Carried out a content and discourse analysis. Participant and nurses' Previous Frameworks, and these last ones' discourses as well, reveal a current technical rationality (unidirectional, informative,.) yet in practice that perpetuates the role of passive recipient of care. Educational keys constructed from a viewpoint of Dialogic Learning emerge as elements that facilitate overcoming these previous frames limitations. Finally, Reflective Learning launched, has provided advance in professional knowledge and improve health education. Dialogical learning emerges as key to the training and empowerment, where we have seen how practical-reflexive, and not technical, rationality is meanly useful confronting ambiguous and complex situations of self-care practice and education.

Full Text Available Introduction. Student population is the most important social resource of development of post-industrial information society. Therefore, those students will take places of leading experts and will define the level of social and economic wellbeing of the country and its competitiveness in the world in the near future. In this regard, it is important to find out the potential of the student's environment in order to convert it without any loss into social and cultural capital of the state. First of all, this potential is made up by education, qualification and profession and students’ valuable relation to their occupation. Thereby, such valuable relation depends on a degree of a future specialist’ personal maturity, a degree of his/her responsibility for the activity, and readiness for professional selfimprovement.The aims of the present publication are: to analyse the processes of professional self-determination among students; to reveal the tendencies of students’ professional self-determination.Methodology and research methods. The methodological basis of the research involves modern scientific theories formulated within branches of Sociology – Sociology of Education and Sociology of Youth. Representative quota-cluster selective questionnaire survey was used as the main method; that was carried out in seven steps in 1995–2016. The total amount of selection involved 9133 students studying in higher education institutions of Sverdlovsk region – one of the largest administrative territories of Russia.Results and scientific novelty. The results of a unique long-term monitoring are generalized and interpreted. In the course of the monitoring, the dynamics of professional self-determination of student youth was traced by means of such key indicators as follows: motives of the choice of the sphere of employment and educational institution; personal importance of future profession for students; professional plans of students after

Cinema as the Interdisciplinary Conjuncture of Political Thought and History

Full Text Available From the dawn of its history, cinema has been considered as a phenomenon in which different thoughts, among them the political, could be addressed. Indeed, many film-makers have presented various aspects of political norms and the good order of society through movies. However, this combination of the idea and image has been addressed in different ways and among others, as seems, the historical narrative has the potentiality to convey critical and normal political ideas in cinema. Exploring different types of representing the political thought in cinematic historical narratives, the present study attempts to identify cinema’s interdisciplinary potential as a conjuncture for the disciplines of history and political thought.

The Three Laws of Thought, Plus One: The Law of Comparisons

Directory of Open Access Journals (Sweden)

Thomas L. Saaty

2014-02-01

Full Text Available The rules of logic are nearly 2500 years old and date back to Plato and Aristotle who set down the three laws of thought: identity, non-contradiction, and excluded middle. The use of language and logic has been adequate for us to develop mathematics, prove theorems, and create scientific knowledge. However, the laws of thought are incomplete. We need to extend our logical system by adding to the very old laws of thought an essential yet poorly understood law. It is a necessary law of thought that resides in our biology even deeper than the other three laws. It is related to the rudiments of how we as living beings, and even nonliving things, respond to influences as stimuli. It helps us discriminate between being ourselves and sensing that there is something else that is not ourselves that even amoebas seem to know. It is the intrinsic ability to sense and distinguish. This fourth law is the law of comparisons. Although it has been missing from our logical deductions it underlies the other three laws of thought because without it we cannot know what is and what is not.

AMNIOCENTESIS FOR FETAL LUNG MATURITY HAS HISTORICALLY BEEN PERFORMED FOR MANY REASONS: uterine and placental complications, maternal comorbidities, fetal issues, and even obstetric problems. Even though the risks associated with third trimester amniocentesis are extremely low, complications have been documented, including preterm labor, placental abruptions, intrauterine rupture, maternal sepsis, fetal heart rate abnormalities, and fetal-maternal hemorrhage. This review presents the types of tests for fetal lung maturity, presents the indications and tests utilized, and discusses recommendations for when amniocentesis for fetal lung maturity may be appropriate.

Pérez-Figueroa Andrés

2011-10-01

Full Text Available Abstract Background Early maturation in the Atlantic salmon is an interesting subject for numerous research lines. Prior to sea migration, parr can reach sexual maturation and successfully fertilize adult female eggs during the reproductive season. These individuals are known as precocious parr, mature parr or "sneakers". Reasons for early maturation are unknown and this transitory stage is usually considered to be a threshold trait. Here, we compare methylation patterns between mature and immature salmon parr from two different rivers in order to infer if such methylation differences may be related to their maturation condition. First we analyzed genetic differences between rivers by means of AFLPs. Then, we compared the DNA methylation differences between mature and immature parrs, using a Methylation-Sensitive Amplified Polymorphism (MSAP, which is a modification of the AFLPs method by making use of the differential sensitivity of a pair of restriction enzymes isoschizomeres to cytosine methylation. The tissues essayed included brain, liver and gonads. Results AFLPs statistical analysis showed that there was no significant differentiation between rivers or a significant differentiation between maturation states in each river. MSAP statistical analysis showed that among the three tissues sampled, the gonads had the highest number of significant single-locus variation among populations with 74 loci followed by brain with 70 and finally liver with only 12. Principal components analysis (PCA of the MSAP profiles revealed different profiles among different tissues (liver, brain and testis clearly separating maturation states in the testis tissue when compared to the liver. Conclusions Our results reveal that genetically-similar mature and immature salmon parr present high levels of DNA methylation variation in two of the three analyzed tissues. We hypothesize that early maturation may be mostly mediated by epigenetic processes rather than by

2012-01-01

Background Considerable variations in the development stage among patients of the same chronological age have led to introduce the concept of the developmental age based on the maturation of different organs such as cervical vertebrae or teeth. Objectives The purpose of this study was to investigate the correlation between the stages of tooth calcification and the cervical vertebral maturation in Iranian females. Patients and Methods Four hundred females (age range, 8 to 14 years) participated in the study. To determine the dental maturational stage, calcification of the mandibular teeth except for third molars were rated according to the method suggested by Demirjian et al. To evaluate the stage of skeletal maturation, cervical vertebral morphologic changes were assessed on lateral cephalometric radiographs according to the method explained by Baccetti et al. Correlations between bone maturation and teeth calcification were showed by Spearman's correlation and Kendall’s tau-b coefficients. The relevant associations were investigated by ordinal logistic regression models. Results Correlations between the two stages were observed in the first and second premolars, canine and central incisors. All these correlations were significant. The association between cervical vertebral maturation and tooth calcification was greatest in the lateral incisor (odds ratio (OR) = 11, 95% confidence interval (CI): 6.6-18.3). However, considering the 95% CI for OR, no significant difference was detected among the second molar, first molar and lateral incisor. Conclusion The relationship between calcification of teeth and maturation of cervical bones was significant. Bone maturation can be predicted by using teeth calcification stages, especially in the second molar, first molar and lateral incisor. PMID:23599706

Java plum (Syzygium cumini Lam.) is a rich source of polyphenolics with many purported health benefits, but the effect of maturation on polyphenolic content is unknown. Freeze-dried samples of Java plum from seven different maturity stages were analyzed for anthocyanin, flavonol, flavanonol and hydrolysable tannin composition by HPLC. Anthocyanins were first detected at the green-pink stage of maturity and increased throughout maturation with the largest increase occurring from the dark purple to black stages of maturation. Levels of gallotannins, ellagitannins, flavonols, gallic acid and ellagic acid were highest at early stages of maturation and decreased as the fruit ripened. For production of antioxidant-rich nutraceutical ingredients, fruit should be harvested immature to obtain extracts rich in hydrolysable tannins and flavonols. The exceptional anthocyanin content of black fruit may prove useful as a source of a natural colorant. Copyright © 2017 Elsevier Ltd. All rights reserved.

Nowadays because of lots of reasons, lifespan is increasing and caregiving of aged people becomes more and more important. Today it is understood how the professional care of aged people is significant, instead of being carried out by volunteers. Because of this, in this study we aimed to understand the problems, and thoughts of aging of caregivers who are working in nursing homes. This study was made using the so-called qualitative research, which is one of the research designs. Including general aim, interviews with 13 caregivers with structured questions, supported by spontaneous ones. Interviews were taped and transcribed verbatim. After that, they were grouped with the same themes. Thoughts are grouped with three main themes, which are about "aging", "working life", "caregiving of aged people". Aged people are described like people who are dependent, need interest, and represent the wisdom period. Also caregiving is described like both good job and punishment. Besides, the reason of working as a caregiver, is the economic needs. The suggestions of caregivers are increasing payment, giving psychological and emotional support, and also improving physical conditions. Economic satisfaction of caregivers, giving psychological support, caregivers with aged people and improving physical conditions are important to increase the quality of professional caregiving.

The present communication is an attempt to demonstrate the influence of melatonin on the action of maturation inducing hormone (MIH) on the maturation of oocytes in carps. The oocytes from gravid female major carp Labeo rohita were isolated and incubated separately in Medium 199 containing (a) only MIH (1 microg/ml), (b) only melatonin (at concentrations of 50, 100 or 500 pg/ml), and (c) both melatonin and MIH, but at different time intervals. In the latter group, melatonin was added to the incubating medium either (i) 4 h before addition of MIH, (ii) 2 h before addition of MIH, (iii) co-administered with MIH (0 h interval) or (iv) 2 h after addition of MIH. In each case, oocytes were further incubated for 4, 8, 12 or 16 h post- administration of MIH, and the effects of treatment on oocyte maturation were evaluated by considering the rate (%) of germinal vesicle breakdown (GVBD). Incubation of oocytes in a medium containing only melatonin did not result in GVBD of any oocyte. Nearly all the oocytes underwent GVBD when incubated with MIH for 16 h. Administration of melatonin along with MIH (at 0 h interval) or 2 h after addition of MIH did not result in any significant change in the rate of GVBD compared to that in a medium containing only MIH. However, it was quite interesting to observe that incubation of oocytes with melatonin especially 4 h prior to addition of MIH in the medium, led to an accelerated rate of GVBD in the oocytes. Experiments with the oocytes of another major carp Cyprinus carpio following an identical schedule depicted similar results except a difference in the optimum melatonin dose. In L. rohita, 50 pg/ml melatonin had maximum acceleratory effect on MIH-induced GVBD of oocytes, while it was 100 pg/ml in C. carpio. Further study revealed that pre-incubation with melatonin accelerates the action of MIH on the formation of a complex of two proteins (MPF), a regulatory component called cyclin B and the catalytic component protein kinase known as

We discuss Carol Gilligan's original concept of mature care in the light of the altruistic approach to caring and good clinical judgment. In particular, we highlight how the concept of mature care can capture important challenges in today's nursing. Further, we illuminate how mature care might differ normatively from an altruistic approach to caring and the traditional prudential virtues in nursing. We also discuss similarities between mature care and virtue ethics. For nursing and nurses' identity, in today's health care system that is increasingly pressured to 'produce' health, we believe it is important to both developing further theories on mature care and having normative discussions about care. © The Author(s) 2014.
