Suicide note themes and suicide prevention.

Science.gov (United States)

Foster, Tom

2003-01-01

The aim was to determine if suicide note themes might inform suicide prevention strategies. The themes of 42 suicide notes from the Northern Ireland Suicide Study (major psychological autopsy study) were examined. The commonest themes were "apology/shame" (74%), "love for those left behind" (60%), "life too much to bear" (48%), "instructions regarding practical affairs post-mortem" (36%), "hopelessness/nothing to live for" (21%) and "advice for those left behind" (21%). Notes of suicides with major unipolar depression were more likely than notes of suicides without major unipolar depression to contain the themes "instructions regarding practical affairs post-mortem" (67% versus 19%, p = 0.005) and "hopelessness/nothing to live for" (40% versus 11%, p = 0.049). Notes of suicides with a previous history of deliberate self-harm were less likely than notes of suicides without a history of deliberate self-harm to contain the theme "apology/shame" (58% versus 87%, p = 0.04). Notes of elderly suicides were more likely than non-elderly notes to contain the theme "burden to others" (40% versus 3%, p = 0.03). The fact that three quarters of suicide notes contained the theme "apology/shame" suggests that the deceased may have welcomed alternative solutions for their predicaments. Scrutiny of suicide note themes in the light of previous research findings suggests that cognitive therapy techniques, especially problem solving, may have an important role to play in suicide prevention and that potential major unipolar depressive (possibly less impulsive) suicides, in particular, may provide fertile ground for therapeutic intervention (physical and psychological). Ideally all primary care doctors and mental health professionals working with (potentially) suicidal people should be familiar with basic cognitive therapy techniques, especially problem solving skills training.

I am pleased to present this summary of the Division 1000 Science and Technology Strategic Plan. This plan was created with considerable participation from all levels of management in Division 1000, and is intended to chart our course as we strive to contribute our very best in service of the greater Laboratory strategy. The plan is characterized by four strategic themes: Mission Engagement, Bold Outcomes, Collaborative Environment, and the Safety Imperative. Each theme is accompanied by a brief vision statement, several goals, and planned actions to support those goals throughout FY16. I want to be clear that this is not a strategy to be pursued in tension with the Laboratory strategic plan. Rather, it is intended to describe “how” we intend to show up for the “what” described in Sandia’s Strategic Plan. I welcome your feedback and look forward to our dialogue about these strategic themes. Please join me as we move forward to implement the plan in the coming year.

Ask an anatomist: Identifying global trends, topics and themes of academic anatomists using twitter.

Science.gov (United States)

Marsland, Madeleine J; Lazarus, Michelle D

2018-05-06

Social media (SoMe) is increasingly used in higher education (HE) to access knowledge and enable global communication. The SoMe platform Twitter ® is particularly beneficial in these contexts because it is readily accessible, easily searchable (via hashtags) and global. Given these advantages, the twitter platform @AskAnatomist was created to foster a global weekly tweet chat, where students and academics can ask and address anatomy-related questions. The aim of this study was to identify themes arising in the early stages of the @AskAnatomy Twitter community to gain insights into current needs/key areas for academic anatomists, students, and other followers. A qualitative analysis of tweets including the hashtag #AnatQ, (the associated @AskAnatomist hashtag), was undertaken to achieve this aim. Thematic analysis revealed three core themes arising in the formative stages of the @AskAnatomist Twitter site: (1) anatomical education modalities, (2) specific anatomy content, and (3) research motivations. These themes reveal controversies within the field of anatomical sciences, areas for potential education resource improvement and research, as well as the humor of anatomists. Though the original intent of the @AskAnatomist site was to engage the general public in anatomy content and knowledge, tweet analysis suggests that academic anatomists were the primary active "tweeters". Interestingly, this analysis reveals that the @AskAnatomist site progressed into a web-based community of practice (CoP), suggesting an additional benefit of SoMe communities in the field of anatomy.

Marcelo Porte

Full Text Available ABSTRACT The passage of the Sarbanes-Oxley Act (SOX was a turning point in auditing and in auditors practice for the academic world. Research concerning the characterization of academic production related to auditing is in its third decade. Its analysis is accomplished by means of definition of keywords, abstracts or title, and information on thematic association within the academic production itself in auditing is undisclosed. In order to revise this gap in auditing literature, this study identified the main themes in auditing and their association in post-SOX era by analyzing the content of objectives and hypothesis of 1,650 publications in Web of Science (2002-2014. The findings in this study extended those from the study by Lesage and Wechtler (2012 from 16 auditing thematic typologies to 22. The results demonstrate that the themes audit report & financial statement users, corporate governance, audit market, external audit, socio-economic data of the company, international regulation, and fraud risk & audit risk were the most addressed in the publications about auditing. Corporate governance has a broader association with the other themes in the area. Future researches may use these themes and relate them to the methodologies applied to audit studies.

Universal design characteristic on themed streets

Harsritanto, Bangun IR; Indriastjario; Wijayanti

2017-12-01

People around the world can access the streets to fulfil their daily activities regardless of their gender, age, and abilities. The streetscape is an urban public space which is built to facilitate the basic needs of people as social being. The themed street is an urban streetscape designed and built in detail with a theme or special purpose in an of urban development process. Universal design facilitates the full range of human diversity as physical appearance, perception, cognitive abilities, sizes, and shapes. By designing for the diversity, the specialized streets become more functional and user-friendly. The purpose of this study is to examine several design characteristics of themed streets in several countries from three different continents using universal design principles for giving proper directions to develop more user-friendly streets. Literature review and case study were used as research methods. The literature review was extracted and compiled from manuscripts, streetscape design books, and from universal design principles. Furthermore, the constructed theory were used to examine the case studies of themed streets. The findings indicated that themed streets’ character design were strongly influenced by local cultural aspect even though the basic guidelines were universal design principles; the resumed design direction can be suggested universal along with the richness of local aspects.

Detecting Themed Streets Using a Location Based Service Application

Directory of Open Access Journals (Sweden)

Byeongsuk Ji

2016-07-01

Full Text Available Various themed streets have recently been developed by local governments in order to stimulate local economies and to establish the identity of the corresponding places. However, the motivations behind the development of some of these themed street projects has been based on profit, without full considerations of people’s perceptions of their local areas, resulting in marginal effects on the local economies concerned. In response to this issue, this study proposed a themed street clustering method to detect the themed streets of a specific region, focusing on the commercial themed street, which is more prevalent than other types of themed streets using location based service data. This study especially uses “the street segment” as a basic unit for analysis. The Sillim and Gangnam areas of Seoul, South Korea were chosen for the evaluation of the adequacy of the proposed method. By comparing trade areas that were sourced from a market analysis report by a reliable agent with the themed streets detected in this study, the experiment results showed high proficiency of the proposed method.

Enhancing Students’ Local Knowledge Through Themed Garden Project

Directory of Open Access Journals (Sweden)

Esa Norizan

2015-01-01

Full Text Available Traditional or local knowledge is a major issue to be focused on, particularly since the implementation of the Strategic Plan for Biodiversity 2011–2020 and the Aichi Targets “Living in Harmony with Nature”. According to the strategic goals, by 2020, conservation of biodiversity and its sustainable use incorporate what local and indigenous communities have within their traditional knowledge, innovation and practice and their customary use of biological resources are respected at all relevant levels. The older generation among the local people usually use medicinal herbs for various ailments, health care and other cultural purposes. However, encroaching industrialization and the changes in today’s life styles are responsible for the decreasing practice in the local use of herbs especially for healing purposes. It is, therefore, felt worthwhile to encourage young generations such as school children to gain knowledge about these local herbs and record the native uses of these herbs before the information is lost. One biodiversity education program was conducted to facilitate secondary school students to set up a themed garden and find out the local knowledge of the plants they grew in their garden from their family members or communities. The findings revealed that students’ local knowledge on healing improved after they joined the program. Therefore, it is proposed that the themed garden project can enhance students’ local knowledge.

The Science and Technology (S&T) Division 1000 Strategic Plan includes the Themes, Goals, and Actions for FY16. S&T will continue to support the Labs Strategic plan, Mission Areas and Program Management Units by focusing on four strategic themes that align with the targeted needs of the Labs. The themes presented in this plan are Mission Engagement, Bold Outcomes, Collaborative Environment, and the Safety Imperative. Collectively they emphasize diverse, collaborative teams and a self-reliant culture of safety that will deliver on our promise of exceptional service in the national interest like never before. Mission Engagement focuses on increasing collaboration at all levels but with emphasis at the strategic level with mission efforts across the labs. Bold Outcomes seeks to increase the ability to take thoughtful risks with the goal of achieving transformative breakthroughs more frequently. Collaborative environment strives for a self-aware, collaborative working environment that bridges the many cultures of Sandia. Finally, Safety Imperative aims to minimize the risk of serious injury and to continuously strengthen the safety culture. Each of these themes is accompanied by a brief vision statement, several goals, and planned actions to support those goals throughout FY16 and leading into FY17.

There has been little exploration of journaling in medical student education. To document the themes on which medical students reflect during training. We evaluated journals kept by primary care medical students to identify prominent themes and determine change or constancy in themes over time. We looked at third-year medical students participating in a required primary care clerkship in a university-affiliated, community-based family medicine residency program with a rural catchment area. During 1994-1996 and 2001-2003, students were asked to keep weekly journals reflecting on their thoughts and feelings regarding "topical content, course processes and methods, and personal reflections on becoming a doctor." Faculty evaluated journals to identify change or constancy in themes over time. Prominent themes included gender issues, professional identity emergence, career choice, and rural practice, the experience of learning, the experience of relating to patients, and the nature of medical practice. We found both constancy and change in student journal themes over time. Changes in journal themes appeared to correlate with outside events and educational trends, including increased attention to reflective practice, changing demographics in medicine and the increasing acceptance of female physicians, and personal life events.

John S Liu

Full Text Available The body of literature addressing the phenomenon related to social networking services (SNSs has grown rather fast recently. Through a systematic and quantitative approach, this study identifies the recent SNS research themes, which are the issues discussed by a coherent and growing subset of this literature. A set of academic articles retrieved from the Web of Science database is used as the basis for uncovering the recent themes. We begin the analysis by constructing a citation network which is further separated into groups after applying a widely used clustering method. The resulting clusters all consist of articles coherent in citation relationships. This study suggests eight fast growing recent themes. They span widely encompassing politics, romantic relationships, public relations, journalism, and health. Among them, four focus their issues largely on Twitter, three on Facebook, and one generally on both. While discussions on traditional issues in SNSs such as personality, motivations, self-disclosure, narcissism, etc. continue to lead the pack, the proliferation of the highlighted recent themes in the near future is very likely to happen.

Pettigrew, Simone; Roberts, Michele; Chapman, Kathy; Quester, Pascale; Miller, Caroline

2012-04-01

The ability of food advertising to trigger food consumption and influence social norms relating to food consumption has resulted in increasing attention being given to the prevalence and nature of food advertising. The present study investigated the use of negative themes in food advertisements aired on Australian television to determine the prevalence of depictions of violence/aggression, mocking, nagging, boredom, loneliness, food craving, mood enhancement, and the emotional use of food across 61 days of programming time. The results suggest that advertisers are using negative themes to capture attention and invoke an emotional response in the target audience. Sixteen percent (14,611) of the 93,284 food advertisements contained negative themes, with mood enhancement and food craving being the most commonly depicted negative themes. Advertisements with negative themes were more likely to be for non-core foods and to be aired during children's popular viewing times than at other times. The potential for negative themes in food advertising to promote unhealthy food consumption behaviors among children is likely to be of concern to policy makers. Building on this exploratory study, further research is needed to investigate how nutrition-related decision making is affected by exposure to food advertisements employing negative emotional themes.

2014-12-01

As part of an NSF TUES Type 3 project entitled "Google Earth for Onsite and Distance Education (GEODE)," we are assembling a "Grand Tour" of locations on Earth and other terrestrial bodies that every geoscience student should know about and visit at least in virtual reality. Based on feedback from colleagues at previous meetings, we have identified nine Grand Tour themes: "Plates and Plumes," "Rocks and Regions," "Geology Through Time," "The Mapping Challenge*," "U.S. National Parks*," "The Magical Mystery Tour*," "Resources and Hazards," "Planets and Moons," and "Top of the Pops." Themes marked with an asterisk are most developed at this stage and will be demonstrated in real time. The Mapping Challenge invites students to trace geological contacts, measure bedding strike and dip and the plunge, trend, and facing of a fold. There is an advanced tool for modeling periclinal folds. The challenge is presented in a game-like format with an emphasis on puzzle-solving that will appeal to students regardless of gender. For the tour of U.S. national parks, we divided the most geologically important parks into four groups—Western Pacific, West Coast, Rockies, and East Coast. We are combining our own team's GigaPan imagery with imagery already available on the Internet. There is a great deal of imagery just waiting to be annotated for geological education purposes. The Magical Mystery Tour takes students to Google Streetview locations selected by instructors. Students are presented with questions or tasks and are given automatic feedback. Other themes are under development. Within each theme, we are crowd-sourcing contributions from colleagues and inviting colleagues to vote for or against proposed locations and student interactions. The GEODE team includes the authors and: Heather Almquist, Stephen Burgin, Cinzia Cervato, Gene Cooper, Paul Karabinos, Terry Pavlis, Jen Piatek, Bill Richards, Jeff Ryan, Ron Schott, Kristen St. John, and Barb Tewksbury.

Preferential use of central metabolism in vivo reveals a nutritional basis for polymicrobial infection.

Directory of Open Access Journals (Sweden)

Christopher J Alteri

2015-01-01

Full Text Available The human genitourinary tract is a common anatomical niche for polymicrobial infection and a leading site for the development of bacteremia and sepsis. Most uncomplicated, community-acquired urinary tract infections (UTI are caused by Escherichia coli, while another bacterium, Proteus mirabilis, is more often associated with complicated UTI. Here, we report that uropathogenic E. coli and P. mirabilis have divergent requirements for specific central pathways in vivo despite colonizing and occupying the same host environment. Using mutants of specific central metabolism enzymes, we determined glycolysis mutants lacking pgi, tpiA, pfkA, or pykA all have fitness defects in vivo for P. mirabilis but do not affect colonization of E. coli during UTI. Similarly, the oxidative pentose phosphate pathway is required only for P. mirabilis in vivo. In contrast, gluconeogenesis is required only for E. coli fitness in vivo. The remarkable difference in central pathway utilization between E. coli and P. mirabilis during experimental UTI was also observed for TCA cycle mutants in sdhB, fumC, and frdA. The distinct in vivo requirements between these pathogens suggest E. coli and P. mirabilis are not direct competitors within host urinary tract nutritional niche. In support of this, we found that co-infection with E. coli and P. mirabilis wild-type strains enhanced bacterial colonization and persistence of both pathogens during UTI. Our results reveal that complementary utilization of central carbon metabolism facilitates polymicrobial disease and suggests microbial activity in vivo alters the host urinary tract nutritional niche.

As this plan represents a continuation of the work we started last year, the four strategic themes (Mission Engagement, Bold Outcomes, Collaborative Environment, and Safety Imperative) remain the same, along with many of the goals. You will see most of the changes in the actions listed for each goal: We completed some actions, modified others, and added a few new ones. As I’ve stated previously, this is not a strategy to be pursued in tension with the Laboratory strategic plan. The Division 1000 strategic plan is intended to chart our course as we strive to contribute our very best in service of the greater Laboratory strategy. I welcome your feedback and look forward to our dialogue about these strategic themes. Please join me as we move forward to implement the plan in the coming months.

Analysis and Comparison of Naturalistic Themes in Iranian and Britain Modern Children's Poems

Directory of Open Access Journals (Sweden)

Shayesteh Ebrahimi

2016-08-01

Full Text Available Today, children's literature given the concept of childhood, has gained a special status in the studies of humanities. Children's poetry is one of the branches of this type of literature. Naturalistic themes have the highest frequency among the themes of children poems in two countries. The population of this research consists of collections that have been published from 1921 to 2011. Children's literature was born in England in the eighteenth century and before that the first didactic books for children had come into existence in England. In addition, due to industrial growth, the emergence of the new middle class and expansion of formal education the UK was pioneering among Europe and the world countries. Therefore, to find the roots of the formation of children's literature should be referred to the UK. Therefore, in this paper Britain children’s poem has been selected to be compared with Iranian children’s poem so that by revealing the similarities and differences one can deal with the pathology of poems for children in Iran and to detect shortcomings and strengths and present some guidelines that be helpful for children and young poets as well as critics and researchers in this field. Keywords: Naturalistic themes, children literature, Iranian children's poems, Britain children's poems, comparative literature

The Internet Marketing of Disney Theme Parks

Carol J. Auster

2013-03-01

Full Text Available The purpose of this study was to analyze the portrayal of gender and race in the images on the official Disney websites used to market five theme parks: the Disneyland Parks in California, Paris, Tokyo, and Hong Kong, and the Magic Kingdom in Florida. This is important because of the growth of e-commerce, Disney’s global influence, and the potential impact on those who view the images. The 452 images that had Disney human characters, human-like characters, animals, cast members, or guests were coded for gender. The main gender hypothesis, that the percentage of male-dominated images would exceed the percentage of female-dominated images, was tested using gender disparity values, which measured the gap between the percentage of male-dominated and female-dominated images. The hypothesis tended to be supported overall, and for most of the resorts (e.g., Florida, lands (e.g., Adventureland, and activities (attractions, entertainment, dining for human characters, human-like characters, animals, and cast members, but not for guests. Furthermore, the hypotheses that gender disparity values would be highest for images of animals and lowest for images of guests was supported for all five resorts, six of eight lands, and all three activities. Additional analysis also revealed the preponderance of same-sex pairings in parent–child combinations in the images. With regard to race, while the images of some theme parks displayed more racial diversity among their guests than others, in some images, individuals of different races were shown interacting whereas in others they were not. Explanations for these findings and suggestions for future research are discussed.

Two routes toward optimism: how agentic and communal themes in autobiographical memories guide optimism for the future.

Science.gov (United States)

Austin, Adrienne; Costabile, Kristi

2017-11-01

Autobiographical memories are particularly adaptive because they function not only to preserve the past, but also to direct our future thoughts and behaviours. Two studies were conducted to examine how communal and agentic themes of positive autobiographical memories differentially predicted the route from autobiographical memories to optimism for the future. Across two studies, results revealed that the degree to which participants focused on communal themes in their autobiographical memories predicted their experience of nostalgia. In turn, the experience of nostalgia increased participants' levels of self-esteem and in turn, optimism for the future. By contrast, the degree to which participants focused on agentic themes in their memories predicted self-esteem and optimism, operating outside the experience of nostalgia. These effects remained even after controlling for self-focused attention. Together, these studies provide greater understanding of the interrelations among autobiographical memory, self-concept, and time, and demonstrate how agency and communion operate to influence perceptions of one's future when thinking about the past.

Giovansili, Iama; Belange, Georeges; Affortit, Aude

2013-01-01

We report the case of a patient with Cushing disease revealed by bilateral central serous chorioretinopathy (CSCR). We present the clinical history, physical findings, laboratory results, and imaging studies of a 53-year-old Chinese woman with a Cushing disease revealed by bilateral CSCR. The association with CSCR and the pertinent literature are reviewed. A 53-year-old patient initially presented to the Department of Ophthalmology with a 4-week history of decreased vision in the left eye. Standard ophthalmologic examination and fluorescein angiography established the diagnosis of bilateral CSCR. Systemic clinical signs and biochemical analysis indicated hypercortisolism. Magnetic resonance imaging (MRI) of the pituitary gland showed a left-side lesion compatible with a microadenoma. The diagnosis of Adrenocorticotropic hormone (ACTH)-dependent Cushing syndrome secondary to a pituitary microadenoma was selected. Endoscopic endonasal transsphenoidal surgery was performed and the pituitary adenoma was successfully removed. The histology confirmed the presence of ACTH-immunopositive pituitary adenoma. Early postoperative morning cortisol levels indicated early remission. At 6 weeks postoperatively, the patient's morning cortisol remains undetectable, and serous retinal detachments had regressed. CSCR is an uncommon manifestation of endogenous Cushing syndrome. It can be the first presentation of hypercortisolism caused by Cushing disease. CSCR should be considered when assessing patients with Cushing syndrome complaining of visual disorders. On the other hand, it is useful in patients with an atypical form of CSCR to exclude Cushing's syndrome.

Multiple cooling episodes in the Central Tarim (Northwest China) revealed by apatite fission track analysis and vitrinite reflectance data

Science.gov (United States)

Chang, Jian; Qiu, Nansheng; Song, Xinying; Li, Huili

2016-06-01

Apatite fission track and vitrinite reflectance are integrated for the first time to study the cooling history in the Central Tarim, northwest China. The paleo-temperature profiles from vitrinite reflectance data of the Z1 and Z11 wells showed a linear relationship with depth, suggesting an approximately 24.8 °C/km paleo-geothermal gradient and 2700-3900 m of erosion during the Early Mesozoic. The measured apatite fission track ages from well Z2 in the Central Tarim range from 39 to 159 Ma and effectively record the Meso-Cenozoic cooling events that occurred in Central Tarim. Moreover, two cooling events at 190-140 Ma in the Early Jurassic-Early Cretaceous and 80-45 Ma in the Late Cretaceous-Paleocene revealed by measured AFT data and thermal modeling results are related to the collisions of the Qiangtang-Lhasa terranes and the Greater India Plate with the southern margin of the Eurasian Plate, respectively. This study provides new insights into the tectonic evolution of the Tarim Basin (and more broadly Central Asia) and for hydrocarbon generation and exploration in the Central Tarim.

Ryan, Virginia; Edge, Andrew

2012-07-01

Describing the processes underlying play therapy is important for evidence based practice in child therapy. Employing play themes to describe children's play session contents is in widespread use by practitioners, but an adequate classification of these themes for non-directive play therapy practice has not yet been established. This article sets out to fill this gap by first describing how themes can be distinguished and distilled from the contents of play therapy contents. Second, a classification of main themes and sub-themes with exemplars to illustrate these concepts which is compatible with non-directive play therapy practice is set out. Finally a pilot project with experienced play therapists to test this classification in practice is suggested, along with the research questions that will need to be investigated in the shorter and longer terms.

Museums as Theme Parks - A Possible Marketing Approach?

Directory of Open Access Journals (Sweden)

Alexandra ZBUCHEA

2015-09-01

Full Text Available Museums compete increasingly more with very diverse entertainment providers, such as theme parks, despite the fact that their offer is mainly cultural. Museums have had to be more active and they have had to diversify their offer, in order to be more popular, therefore to better achieve their complex cultural missions. They should be more “market oriented” and aim to develop their programs according with their visitors’ needs and desires, as well as with the evolutions in the contemporary society.  One answer to this challenge would be the controversial theme parkisation of museums. The paper discusses in what extent the market approach of theme parks could be a viable marketing strategy for museums. It underlines several differences and similarities between the marketing approaches of museums and theme parks, in order to better understand how a museum could preserve its cultural functions, while obtaining economic success. Only the latter would allow it to better develop its cultural activity and thus to better serve its visitors and the community.

To set up and apply the evaluation standards for photography of schistosomiasis control theme, so as to offer the scientific advice for enriching the health information carrier of schistosomiasis control. Through the literature review and expert consultation, the evaluation standard for photography of schistosomiasis control theme was formulated. The themes were divided into 4 projects, such as new construction, natural scenery, working scene, and control achievements. The evaluation criteria of the theme photography were divided into the theme (60%), photographic composition (15%), focus exposure (15%), and color saturation (10%) . A total of 495 pictures (sets) from 59 units with 77 authors were collected from schistosomiasis epidemic areas national wide. After the first-step screening and second-step evaluation, the prizes of 3 themes of control achievements and new construction, working scene, and natural scenery were selected, such as 6 pictures of first prize, 12 pictures of second prize, 18 pictures of third prize, and 20 pictures of honorable prize. The evaluation standards of theme photography should be taken into the consideration of the technical elements of photography and the work specification of schistosomiasis prevention and control. In order to improve the ability of records for propaganda purpose of schistosomiasis control and better play a role of guiding correct propaganda, the training and guidance of photography of professionals should be carried out.

Brennan, Emily; Gibson, Laura A; Kybert-Momjian, Ani; Liu, Jiaying; Hornik, Robert C

2017-01-01

Behavior change campaigns typically try to change beliefs that influence behaviors, with targeted beliefs comprising the campaign theme. We present an empirical approach for choosing among a large number of potential themes, and results from the implementation of this approach for campaigns aimed at 4 behavioral targets: (1) preventing smoking initiation among youth, and (2) preventing initiation, (3) stopping progression to daily smoking and (4) encouraging cessation among young adults. An online survey of 13- to 17-year-olds and 18- to 25-year-olds in the United States (US), in which 20 potential campaign themes were represented by 154 beliefs. For each behavioral target, themes were ranked based on the strength of belief-intention and belief-behavior associations and size of the population not already endorsing the beliefs. The most promising themes varied across behavioral targets but 3 were consistently promising: consequences of smoking for mood, social acceptance and social popularity. Using a robust and systematic approach, this study provides campaign developers with empirical data to inform their selection of promising themes. Findings related to the campaign to prevent initiation among youth informed the development of the US Food and Drug Administration's "The Real Cost" campaign.

Inflazione, disoccupazione e banca centrale: temi per una riconsiderazione critica (Inflation, unemployment and the Central Bank: Themes for a critical reappraisal

Directory of Open Access Journals (Sweden)

Paolo Sylos Labini

2012-04-01

Full Text Available Two propositions are discussed, the first to be attributed to the monetarists ("the variations of the monetary base determine those of prices", the second to certain Keynesian economists ("the variations of prices ultimately depend on the rate of unemployment". The author argues that both propositions are wrong. As for the former, it is maintained that inflationary impulses do not originate from the quantity of money but from the activity of firms, which, however, can be influenced by the policy of the central bank. As for the latter, the rate of unemployment appears to be only one of several vari-ables affecting the behaviour of wages and prices. A critical reappraisal of the explanation of inflation is now particularly important since the European Central Bank will become operative at the be-ginning of the next year.  JEL Codes: E31, E32

Golde, J A; Strassberg, D S; Turner, C M; Lowe, K

2000-07-01

This study examined the independent and interactive effects of sexual explicitness and degrading themes toward women on mens' attitudes following exposure to video presentations of male-female interactions. Subjects were 83 male college students who viewed video vignettes under one of four stimulus conditions: (a) sexually explicit/degrading, (b) sexually explicit/nondegrading, (c) nonexplicit/degrading, and (d) nonexplicit/nondegrading. Results revealed that men exposed to degrading material, regardless of explicitness, were significantly more likely to express attitudes supportive of rape, while explicitness had no significant main or interactive effect on these attitudes. Further, the interaction of explicitness with degradation was found to impact scores on a measure of sexual callousness. Theoretical and clinical implications of these findings are discussed.

Pauses in Striatal Cholinergic Interneurons: What is Revealed by Their Common Themes and Variations?

Directory of Open Access Journals (Sweden)

Yan-Feng Zhang

2017-10-01

Full Text Available Striatal cholinergic interneurons, the so-called tonically active neurons (TANs, pause their firing in response to sensory cues and rewards during classical conditioning and instrumental tasks. The respective pause responses observed can demonstrate many commonalities, such as constant latency and duration, synchronous occurrence in a population of cells, and coincidence with phasic activities of midbrain dopamine neurons (DANs that signal reward predictions and errors. Pauses can however also show divergent properties. Pause latencies and durations can differ in a given TAN between appetitive vs. aversive outcomes in classical conditioning, initial excitation can be present or absent, and a second pause can variably follow a rebound. Despite more than 20 years of study, the functions of these pause responses are still elusive. Our understanding of pause function is hindered by an incomplete understanding of how pauses are generated. In this mini-review article, we compare pause types, as well as current key hypotheses for inputs underlying pauses that include dopamine-induced inhibition through D2-receptors, a GABA input from ventral tegmental area, and a prolonged afterhyperpolarization induced by excitatory input from the cortex or from the thalamus. We review how each of these mechanisms alone explains some but not all aspects of pause responses. These mechanisms might need to operate in specific but variable sets of sequences to generate a full range of pause responses. Alternatively, these mechanisms might operate in conjunction with an underlying control mechanism within cholinergic interneurons which could potentially provide a framework to generate the common themes and variations seen amongst pause responses.

‘Feeling of despair’ as the leading cluster theme of conceptual descriptive analyses in participatory assessment: Russia Oxfam GB case study

Directory of Open Access Journals (Sweden)

Venera Zakirova

2016-12-01

Full Text Available This article provides a case study on participatory assessment based on experience gained from an EU–Oxfam GB project entitled “Empowering Municipalities to Effectively Address Poverty” conducted in five small towns in Russia. Participatory assessment through focus group discussions (FGDs was the main approach used in the implementation of the project. A participatory assessment was performed through 25 FGDs in five remote areas in central Russia. More than 200 participants representing people living in poverty, such as single mothers, people with disabilities, families with many children, families with disabled children, and pensioners, voluntarily participated in the meetings. Most of the participants were women (75% aged between 25 and 70 years. We consider that the participants’ representation is relevant in accordance with the official poverty studies. Through identification of patterns of recurrent ideas and opinions, a qualitative method helps us understand social phenomena from the views of and on the basis of the opinions of the participants. The FGDs’ narratives underwent pattern analysis, resulting in the framing of the cluster themes and narrative conceptualization. Cluster analysis of the FGDs’ narratives led to the framing of 10 cluster themes of importance, followed by conceptual descriptions and related narratives. The conceptual description of the leading theme, feeling of despair (theme 1, was described by respondents’ expressions/narratives, such as “Nobody needs us and there is no future for us and our children in this town,” the narrative idea that crosscuts the subsequent themes. The following nine themes are of equal importance, are interlinked, and for the major part constitute the leading theme, feeling of despair (theme 1: state social and family support (theme 2; health care (theme 3; who are those living in poverty?

2018-01-01

To give a path for developing a city needs a theme. City’s goal stated in a document of a spatial plan were too broad and insufficient detail in giving a direction. To make more detail and precise, every city has to compose a city theme. It is developed based on the potential, the uniqueness, the excellence, and the sustainability of its human resources, natural resources, and man-made resources. An integration among the three of resources which have the highest score become a theme of the city. The aim of this research was to formulate the conceptual framework to compose a city theme. The research design was the interview survey in Banda Aceh, Banjarmasin, and Kupang. Informants were the government officials, academics, figures, the private sector and public who considered related to the intended information being collected. Having set the conceptual framework, the interview directed to check the implementation in realities. The result was that the conceptual framework could accommodate the phenomenon of composing the theme of the city. Yet, it was a preliminary in nature and needed more research to get a complete result.

Themes of Lust and Love in Popular Music Lyrics From 1971 to 2011

Yasaman Madanikia

2014-08-01

Full Text Available We explored themes related to sexual desire (lust and romantic desire (love in the lyrics of popular music over the past 40 years. We examined whether there have been changes in the prevalence of lust and love themes and changes in how these themes inter-relate in music lyrics over time. The study sample consisted of the top 40 songs of Billboard Year End Hot 100 single songs for every 5 years from 1971 to 2011 (N = 360. There was a linear decrease over time in the proportion of songs with a love theme and in the proportion of songs with a combination of lust and love themes. In contrast, there was a significant increase in the proportion of songs with a theme focusing on lust in the absence of love. Themes of lust in the absence of love were especially prevalent in hip-hop/rap music, although music genre did not account for the changing themes over time. These shifts in themes found in popular music may both influence cultural norms and reflect a cultural shift toward acceptance of sexuality outside of love relationships.

Mapping the First 10 Years with Leximancer: Themes and Concepts in the Sports Management International Journal Choregia

2015-04-01

Full Text Available This study uses Leximancer (a text-mining tool for visualizing the structure of concepts and themes in text to map the published research within Sports Management International Journal Choregia from 2005 to 2014. Drawing on 88 papers, of which 61 were classified as empirical and 27 as non-empirical ones, results reveal that the last half of the examined period concerned works that do not relate to the Greek context, which has been the case during the first years of Choregia’s publication. ‘Sports participation’, ‘physical activity’, ‘Greek football clubs’ – all largely associated with ‘management’ and ‘factors’ – shape the main themes in the studies published within Choregia. In addition, an emphasis on positivistic approaches, through the employment of questionnaires and utilizing students as the population for data collection, appears to be the dominant methodological orientation of the published content in Choregia. Becoming the platform for studies that originate beyond the American, Greek, and Iranian contexts, through special issues and invited contributions in the form of research notes would potentially increase this outlet’s scope and depth (that is, context and themes, respectively.

This study deals with theming of residential space and architecture. In theoretical terms, theming is defined as the application of a narrative to places and the built environment to make them more appealing than they otherwise would be. In a broader sense it is argued that theming is related to an intensified commodification of places through which, in turn, the number of hyperspaces has been increased. While theming primarily has been applied to restaurants, shopping malls or theme parks, t...

Underdeveloped Themes in Qualitative Research: Relationship With Interviews and Analysis.

Science.gov (United States)

Connelly, Lynne M; Peltzer, Jill N

2016-01-01

In this methodological article, the authors address the problem of underdeveloped themes in qualitative studies they have reviewed. Various possible reasons for underdeveloped themes are examined, and suggestions offered. Each problem area is explored, and literature support is provided. The suggestions that are offered are supported by the literature as well. The problem with underdeveloped themes in certain articles is related to 3 interconnected issues: (a) lack of clear relationship to the underlying research method, (b) an apparent lack of depth in interviewing techniques, and (c) lack of depth in the analysis. Underdeveloped themes in a qualitative study can lead to a lack of substantive findings that have meaningful implications for practice, research, and the nursing profession, as well as the rejection of articles for publication. Fully developed themes require knowledge about the paradigm of qualitative research, the methodology that is proposed, the effective techniques of interviewing that can produce rich data with examples and experiences, and analysis that goes beyond superficial reporting of what the participants have said. Analytic problem areas include premature closure, anxiety about how to analyze, and confusion about categories and themes. Effective qualitative research takes time and effort and is not as easy as is sometimes presumed. The usefulness of findings depends on researchers improving their research skills and practices. Increasingly researchers are using qualitative research to explore clinically important issues. As consumers of research or members of a research team, clinical nurse specialists need to understand the nature of this research that can provide in-depth insight and meaning.

The Future of Organization Design: An Interpretative Synthesis in Three Themes

Directory of Open Access Journals (Sweden)

Richard M. Burton

2013-04-01

Full Text Available In the inaugural issue of the Journal of Organization Design (Vol. 1, #1, 2012, noted scholars and experienced practitioners presented their views on the future of organization design. The seven wise and provocative statements were subsequently discussed by members of the Organizational Design Community at a conference held at Harvard University on August 3, 2012. I was asked by JOD to monitor the discussion and identify the broad organization design themes that emerged. Although the discussion was wide ranging, three themes were noticeable. The first theme is that there are fundamentals of organization design, and all agreed that design involves creating a cohesive socio-technical system from a number of constituent elements. The second theme is that the boundaries of many newer organizational forms extend beyond that of the single firm, so the scope of organization design needs to expand to include ecosystems, collaborative communities, industries, and other supra-firm architectures. The third theme involves time and change, requiring a shift in focus from how organizations become stable and predictable to how they can become more agile.

THE EGIPTIAN THEME IN THE WORK OF A. P. CHEKHOV

Directory of Open Access Journals (Sweden)

Elena L. Suzryukova

2017-06-01

Full Text Available The present article deals with the biblical themes of the escape to Egypt and the exodus from Egypt as depicted in the narrative and the epistolary fiction of the writer. In the letters of A. P. Chekhov Egypt is associated with favorable living conditions for those who suffer from lung diseases. Besides, the author was taken with the idea of visiting this country, but his dream did not come true. In the early Anton Chekhov’s short story “Holiday” [“Prazdnichnye”] the motif of the escape to Egypt is put in a humorous context. The same motif along with the motif of the Exodus from Egypt was used by the author in the story “Men” [“Muzhiki”]. Both in the letters and in the stories and novels of the writer, the motif of the escape to Egypt keeps the Christian semantics of Salvation. In the short story “Misery” [“Toska”] Egypt is implicitly present — it is linked with the epigraph to the text, the basis for which is a spiritual verse “Weeping of Joseph, when his brothers sold him in Egypt”. The motif of being in Egyptian slavery — another aspect of the theme in question — translates into a number of works and letters of A. P. Chekhov. This motif is associated with the meanings of freedom and grief. The article reveals and analyses the antinomic images of St. Mary of Egypt and Cleopatra of Egypt. Besides, it explores semantic realization of the set expression “plague of Egypt”.

Meaning and Theme in Indian Style

With a glimpse on what was said and a pause on the poems of Saeb Tabrizi, as one of the most seasoned poets in Indian style, it demonstrates part of his art and also illuminates the relation among word, meaning and theme in his poetry and viewpoint. He established multiple proportions among the concepts in his poem: sometimes he expressed a semantic unit as a content with diversities in word, or in some occasions, he expressed a semantic unit by different contents, with similar or dissimilar content maker elements, or even sometimes he use content maker elements for expressing multiple meanings and so on. Also it is necessary to be noted that when Saeb and the other poets of Indian style, measure the meaning by words, their meant is subjective matter and if the meaning comes with adjectives such as unfamiliar, narrow, distant, and so on, these words have used mainly in order to replace theme.

Centralization and Decentralization in the TRIUMF control system

Dohan, D.A.; Gurd, D.P.

1984-01-01

Distributed control is characterized by a number of different concepts relating to hardware, software, data bases, and control stations. Although some control system designs are more centralized than others, all contain elements of both approaches. In particular, the TRIUMF system contains a unique blend of centralized and distributed attributes, deriving primarily from the multi-sourced CAMAC and memory systems at its executive node. The increased demands of an expanding accelerator laboratory have made it timely to consider strategies for expansion of the TRIUMF Control System. These requirements have led to reflections on one of the major themes of this conference - centralized vs distributed digital control systems for accelerators. This paper discusses the way in which the TRIUMF system successfully combines elements of both approaches

Full Text Available This article describes and interprets fan activities within the theme park space related to a particular fan object. It examines an evolving paradigm wherein the role of theme park visitors is changed. Rather than being perceived as observers of spectacles, they can participate and interact with the environment in new ways. An example of this is Sorcerers of the Magic Kingdom (2012, an interactive role-playing quest and collector card game at Disney's Magic Kingdom Park in Florida. Fans participate in a variety of practices that have dynamically redefined theme park activities. Together, management, designers, and fans have cocreated and reconstructed the theme park experience as one of exploration and participation. Despite multiple levels of control, fans will likewise persist in engagement with activities (in park and online that help shape and interrogate the theme park space.

Magnitude and extent of land subsidence in central Mexico revealed by regional InSAR ALOS time-series survey

Science.gov (United States)

Chaussard, E.; Wdowinski, S.; Amelung, F.; Cabral-Cano, E.

2013-05-01

Massive groundwater extraction is very common in Mexico and is well known to result in land subsidence. However, most surveys dedicated to land subsidence focus on one single city, mainly Mexico City, and thus fail to provide a comprehensive picture of the problem. Here we use a space-based radar remote sensing technique, known as Interferometric Synthetic Aperture Radar (InSAR) to detect land subsidence in the entire central Mexico area. We used data from the Japanese satellite ALOS, processed over 600 SAR images acquired between 2007-2011 and produced over 3000 interferograms to cover and area of 200,000 km2 in central Mexico. We identify land subsidence in twenty-one areas, including seventeen cities, namely from east to west, Puebla, Mexico city, Toluca de Lerdo, Queretaro, San Luis de la Paz, south of San Luis de la Paz, Celaya, south of Villa de Reyes, San Luis Potosi, west of Villa de Arista, Morelia, Salamanca, Irapuato, Silao, Leon, Aguascalientes, north of Aguascalientes, Zamora de Hidalgo, Guadalajara, Ahuacatlan, and Tepic. Subsidence rates of 30 cm/yr are observed in Mexico City, while in the other locations typical rates of 5-10 cm/yr are noticed. Regional surveys of this type are necessary for the development of hazard mitigation plans and efficient use of ground-based monitoring. We additionally correlate subsidence with land use, surface geology, and faults distribution and suggest that groundwater extraction for agricultural, urban, and industrial uses are the main causes of land subsidence. We also reveal that the limits of the subsiding areas often correlate with existing faults, motion on these faults being driven by water extraction rather than by tectonic activity. In all the subsiding locations we observe high ground velocity gradients emphasizing the significant risks associated with land subsidence in central Mexico. Averaged 2007-2011 ground velocity map from ALOS InSAR time-series in central Mexico, revealing land subsidence in 21

Minha trajetória acadêmica inclui uma incursão pelas idéias da fenomnenologia, particularmente pelos pensamentos de Heidegger, ou seja, análise existencial do homem enquanto ser-aí. Nesse sentido, a compreensão da pessoa que decide colocar fim à sua existência, pode se constituir, na perspectiva desta análise, como um caminho para reconstrução e redimensionamento de suas perspectivas existenciais.This essay proposes to reveal facets of the suicide through the discourse of differents authors treating this theme as well as through contacts that I was able to have in my nursing training, through my academic trajectory. This trajectory includes an incursion by phenomenological ideas, mainly by the ideas of Heidegger and his existencial analysis of the man as being-there. In this way, the understanding of a person who decides to finalize his/her existence, can be, by the existencial analysis perspective, a way to reconstruct and redimension his/her existencial perspectives.

Discontinuous Residue and Theme in Higher-Order Semiotic: A Case for Interlocking Systems

Directory of Open Access Journals (Sweden)

Ali Akbar Farahani

2008-11-01

Full Text Available The fallacy persists in discourse analysis research to explore lexicogrammatical phenomena detached from any adjacent plane of the meaning potential. In an attempt to dispel this and toss out some preconceived notions about what a modern SFG vantage point should involve, this study homes in on one aspect of SFG within prose fiction in particular, which is very revealing in terms of how separate system networks are actually in synergistic simultaneity, and how SFG allows one , phenomenally well, to bring such synergies out, getting to the heart of the fact that language pervasively operates on multiple planes of textuality simultaneously. Thus, building upon Halliday’s 2004 work, the quest is if it is interpersonally significant when the Residue is split into two parts; more importantly, if it is also laced with some lexicogrammatical quality on the textual plane, in light of the fairly well-entrenched assumption that there is always Theme at work when the Residue is split. Halliday is the only scholar to touch upon the topic of Discontinuous Residue and its relationship to Marked Theme in the culmination of his groundbreaking career, i.e. his 2004 work. Having driven home the proposal to make into a watchword the ubiquity of interlocking macro-semantic system networks, some pedagogical and research implications and suggestions flowing from this are brought up.

THE FIVE-COLOR THEME IN DONGBA SCRIPTURES

Directory of Open Access Journals (Sweden)

Xu Duoduo 许多多

2018-05-01

Full Text Available I compared the two translated versions of The Advent of Dragons collected during fieldwork with a Ruke Dongba priest and found many inconsistencies in the same scripture and even within single verses. These inconsistencies may derive from oral composition mechanisms, for example, the aim to adapt the content to metric patterns. These complexities are mainly attested in verses related to the five-color theme, in which the five colors correspond to the mythical creatures and landscape in the five spatial directions. In the formulaic tradition of Dongba Culture, this color-related theme is delivered as a whole message produced by mentioning several keywords. However, the various details involving the keywords do not affect the meaning of the message. Consequently, the flexibilities of the content, highlighted as inconsistencies in the word-by-word translation, leave space for variants in the development of the oral culture and become formularized in various branches of Dongbaism.

Previous studies have examined what adolescents find appealing in tobacco and alcohol advertisements and how different themes in advertisements are used to manipulate consumer behaviors. Yet, we know little about the relationship between the themes portrayed in advertisements and youth attitudes towards those themes. This study compared attitudes towards advertisements for different consumer products in a sample of urban and rural adolescent boys in order to examine how key marketing themes impact adolescent attitudes towards those advertisements. Participants were 11- to 16-year-old boys (N = 1220) residing in either urban or rural Ohio Appalachian counties. Each participant viewed five print advertisements (one each for cigarettes, electronic cigarettes (e-cigarettes), smokeless tobacco (SLT), non-alcoholic beverages, and alcohol), presented in a random order, for eight seconds each. All advertisements had appeared in magazines that adolescent males commonly read. Attitudes towards each of the five advertisements were assessed. The advertisements were then coded for the presence of various themes, including social acceptance and masculinity. Analyses were conducted to determine associations between advertisement type and the attitude measure, and between the presence of a theme and the attitude measure. Overall, participants preferred non-tobacco advertisements to tobacco advertisements, rural participants had less positive attitudes and participants who had peers who used tobacco had more positive attitudes. Social acceptance and entertainment themes increased the appeal of SLT advertisements, and sex appeal increased the appeal of e-cigarette advertisements. Conclusions/Importance: Findings suggest that advertisements that promote the social nature of use in SLT advertisements may be of particular concern for their influence on adolescent boys.

Life-style themes of unwed pregnant adolescents who chose to keep their babies.

Science.gov (United States)

Jorgensen, J A; Newlon, B J

1988-12-01

The authors point out that the largest increase in birthrate is accounted for by girls under age 15; the rise in teenage baby keeping is also a major source of alarm in America. The subjects interviewed for this study were currently enrolled in a Teenage Parent Program for girls aged 14-18 in a large southwestern city. All participants in the study were Anglos from middle to lower-middle income families. Participants included 2 15-year-olds, 2 16-year-olds, 3 17-year-olds, and 3 18-year-olds. All were unwed and kept their babies after birth. Each subject participated in a tape-recorded interview which lasted from 30 minutes to 1 hour and included early recollections and birth order information. Transcripts were analyzed and interpreted by 3 expert Adlerian therapists. Examination of these transcripts revealed themes common to the group as a whole. These themes centered around the desire for a close, idealized relationship with someone, the goal of excitement, and the expectation of being confused, unknowing, or afraid. The group also demonstrated a lack of themes centering on their own anger or victimization. They did, however, perceive themselves as being isolated from their parents. Those subjects who shared the same birth order position tended to have specific traits in common. The youngest in terms of birth order tended to use their confusion to keep others involved with them. The only and 1st borough tended to use their confusion and fear to deflect the burden of responsibility which was a strong component of their life-style. Lack of self-esteem was 1 commonly held characteristic. If society wishes to change the current increase in teenage pregnancies, a greater understanding of the importance of belonging and self-worth is needed by the significant adults in young people's lives. Increased understanding could lead to changes within the family and the educational institution. Self-esteem in young people would be encouraged and a sense of belonging developed

Structure of a Spumaretrovirus Gag Central Domain Reveals an Ancient Retroviral Capsid.

Directory of Open Access Journals (Sweden)

Neil J Ball

2016-11-01

Full Text Available The Spumaretrovirinae, or foamy viruses (FVs are complex retroviruses that infect many species of monkey and ape. Despite little sequence homology, FV and orthoretroviral Gag proteins perform equivalent functions, including genome packaging, virion assembly, trafficking and membrane targeting. However, there is a paucity of structural information for FVs and it is unclear how disparate FV and orthoretroviral Gag molecules share the same function. To probe the functional overlap of FV and orthoretroviral Gag we have determined the structure of a central region of Gag from the Prototype FV (PFV. The structure comprises two all α-helical domains NtDCEN and CtDCEN that although they have no sequence similarity, we show they share the same core fold as the N- (NtDCA and C-terminal domains (CtDCA of archetypal orthoretroviral capsid protein (CA. Moreover, structural comparisons with orthoretroviral CA align PFV NtDCEN and CtDCEN with NtDCA and CtDCA respectively. Further in vitro and functional virological assays reveal that residues making inter-domain NtDCEN-CtDCEN interactions are required for PFV capsid assembly and that intact capsid is required for PFV reverse transcription. These data provide the first information that relates the Gag proteins of Spuma and Orthoretrovirinae and suggests a common ancestor for both lineages containing an ancient CA fold.

Two of the papers address explicitly the issue of risk management, while the other three may be related to it in different degrees. One of the critical factors for project success is risk identification, as determined by Chua et al. (1999. The importance of risk management cannot be overemphasized. Failure to identify crucial risk elements in a project can lead to significant project failures in terms of cost and schedule.

Using the Sustainability Monitoring and Assessment Routine (SMART for the Systematic Analysis of Trade-Offs and Synergies between Sustainability Dimensions and Themes at Farm Level

2016-03-01

Full Text Available When trying to optimize the sustainability performance of farms and farming systems, a consideration of trade-offs and synergies between different themes and dimensions is required. The aim of this paper is to perform a systematic analysis of trade-offs and synergies across all dimensions and themes. To achieve this aim we used the Sustainability Monitoring and Assessment Routine (SMART-Farm Tool which operationalizes the Sustainability Assessment of Food and Agriculture Systems (SAFA Guidelines by defining science-based indicator sets and assessment procedures. It identifies the degree of goal achievement with respect to the 58 themes defined in the SAFA Guidelines using an impact matrix that defines 327 indicators and 1769 relations between sustainability themes and indicators. We illustrate how the SMART-Farm Tool can be successfully applied to assess the sustainability performance of farms of different types and in different geographic regions. Our analysis revealed important synergies between themes within a sustainability dimension and across dimensions. We found major trade-offs within the environmental dimension and between the environmental and economic dimension. The trade-offs within the environmental dimension were even larger than the trade-offs with other dimensions. The study also underlines the importance of the governance dimension with regard to achieving a good level of performance in the other dimensions.

The moral theme in Zulu literature: a progression

Directory of Open Access Journals (Sweden)

M. Marggraff

1998-04-01

Full Text Available A moral theme in literature is not only unique to Zulu literature. Despite the relative youth of the modern branch of Zulu literature, any observer can make the interesting and important discovery that the moral theme is predominantly conveyed by the following three literary types: the folktale, the moral story, the detective story. The folktale, belonging to traditional literature, is a very well-developed form, that formed the principal means of teaching both children and adults about good and evil. The birth of modern Zulu literature in 1930 brought with it the emergence of the moral story, a literary type in which good triumphs over evil and in which justice prevails. Further development and changes have led to the appearance of the detective story in which crimes are solved and bad people are punished. This progression has developed due to ever-changing circumstances and a need for relevance.

Spatiotemporal evolution of Calophaca (fabaceae) reveals multiple dispersals in central Asian mountains.

Zhang, Ming-Li; Wen, Zhi-Bin; Fritsch, Peter W; Sanderson, Stewart C

2015-01-01

The Central Asian flora plays a significant role in Eurasia and the Northern Hemisphere. Calophaca, a member of this flora, includes eight currently recognized species, and is centered in Central Asia, with some taxa extending into adjacent areas. A phylogenetic analysis of the genus utilizing nuclear ribosomal ITS and plastid trnS-trnG and rbcL sequences was carried out in order to confirm its taxonomic status and reconstruct its evolutionary history. We employed BEAST Bayesian inference for dating, and S-DIVA and BBM for ancestral area reconstruction, to study its spatiotemporal evolution. Our results show that Calophacais monophyletic and nested within Caragana. The divergence time of Calophaca is estimated at ca. 8.0 Ma, most likely driven by global cooling and aridification, influenced by rapid uplift of the Qinghai Tibet Plateau margins. According to ancestral area reconstructions, the genus most likely originated in the Pamir Mountains, a global biodiversity hotspot and hypothesized Tertiary refugium of many Central Asian plant lineages. Dispersals from this location are inferred to the western Tianshan Mountains, then northward to the Tarbagatai Range, eastward to East Asia, and westward to the Caucasus, Russia, and Europe. The spatiotemporal evolution of Calophaca provides a case contributing to an understanding of the flora and biodiversity of the Central Asian mountains and adjacent regions.

From themes to hypotheses: following up with quantitative methods.

Science.gov (United States)

Morgan, David L

2015-06-01

One important category of mixed-methods research designs consists of quantitative studies that follow up on qualitative research. In this case, the themes that serve as the results from the qualitative methods generate hypotheses for testing through the quantitative methods. That process requires operationalization to translate the concepts from the qualitative themes into quantitative variables. This article illustrates these procedures with examples that range from simple operationalization to the evaluation of complex models. It concludes with an argument for not only following up qualitative work with quantitative studies but also the reverse, and doing so by going beyond integrating methods within single projects to include broader mutual attention from qualitative and quantitative researchers who work in the same field. © The Author(s) 2015.

Prokaryotic Argonautes - variations on the RNA interference theme

Science.gov (United States)

van der Oost, John; Swarts, Daan C.; Jore, Matthijs M.

2014-01-01

The discovery of RNA interference (RNAi) has been a major scientific breakthrough. This RNA-guided RNA interference system plays a crucial role in a wide range of regulatory and defense mechanisms in eukaryotes. The key enzyme of the RNAi system is Argonaute (Ago), an endo-ribonuclease that uses a small RNA guide molecule to specifically target a complementary RNA transcript. Two functional classes of eukaryotic Ago have been described: catalytically active Ago that cleaves RNA targets complementary to its guide, and inactive Ago that uses its guide to bind target RNA to down-regulate translation efficiency. A recent comparative genomics study has revealed that Argonaute-like proteins are also encoded by prokaryotic genomes. Interestingly, there is a lot of variation among these prokaryotic Argonaute (pAgo) proteins with respect to domain architecture: some resemble the eukaryotic Ago (long pAgo) containing a complete or disrupted catalytic site, while others are truncated versions (short pAgo) that generally contain an incomplete catalytic site. Prokaryotic Agos with an incomplete catalytic site often co-occur with (predicted) nucleases. Based on this diversity, and on the fact that homologs of other RNAi-related protein components (such as Dicer nucleases) have never been identified in prokaryotes, it has been predicted that variations on the eukaryotic RNAi theme may occur in prokaryotes.

Multiproxy approach revealing climate and cultural changes during the last 26kyrs in south-central Chile

Science.gov (United States)

Abarzua, Ana M.; Jarpa, Leonora; Martel, Alejandra; Vega, Rodrigo; Pino, Mario

2010-05-01

Multiproxy approach from Purén Lumaco Valley (38°S) describes the paleonvironmental history during the Last Maximum Glacial (LGM) in south-central Chile. Three sediment cores and severals AMS 14C dates were used to perform a complete pollen, diatoms, chironomids, and sedimentological records demonstrating the existence of a large and non profundal paleolake, between 25 and 20kyr BP. Some of these evidence are laminated silty-clay sediments (lacustrine rhythmites), associated with the presence of siderite mineral (FeCO3), besides biological proxies like Fragilaria construens and Stauroforma inermes (planctonic diatoms), and Dicrotendipes sp. and Tanytarsini tribe (littoral chironomids). The pollen ensemble reveals the first glacial refuge of Araucaria araucana forests in the low lands during the LGM. The lake was drained abruptly into a swamp/bog at 12kyr BP and colonized by Myrtaceae wet forest. This evidence suggest the dry/warm climate period of early Holocene in south-central Chile. Later, the sediments indicate variable lacustrine levels, and increase of charcoal particles, associated to current climatic conditions. The pollen spectrum dominated by Myrtaceae and Nothofagus contrasts with a strongly disturb current landscape. Actually, Purén-Lumaco valley constitutes a complex peat-bog system dominated by exotic grasses and forest species (Tritricum aestivum, Pinus radiata and Eucalyptus spp.). Some archaeological antecedents in the area document the human development at ca. 7yrs BP. The greatest archaeological characteristic present in the valley is the kuel, a Mapuche earth accumulation. The presence and extension of almost 300 kuel in the valley reflect the social/economic development, and partly explains why the region was the major resistance area for Spanish colonizer during XVI-XVII centuries. Also the archaeological findings reveal the presence of maize pollen (Zea mays) within their food consumption. The influence of climate and human impact in

Geometric structure of chemistry-relevant graphs zigzags and central circuits

CERN Document Server

Deza, Michel-Marie; Shtogrin, Mikhail Ivanovitch

2015-01-01

The central theme of the present book is zigzags and central-circuits of three- or four-regular plane graphs, which allow a double covering or covering of the edgeset to be obtained. The book presents zigzag and central circuit structures of geometric fullerenes and several other classes of graph of interest in the fields of chemistry and mathematics. It also discusses the symmetries, parameterization and the Goldberg–Coxeter construction for those graphs. It is the first book on this subject, presenting full structure theory of such graphs. While many previous publications only addressed particular questions about selected graphs, this book is based on numerous computations and presents extensive data (tables and figures), as well as algorithmic and computational information. It will be of interest to researchers and students of discrete geometry, mathematical chemistry and combinatorics, as well as to lay mathematicians.

Characterization of Fashion Themes Using Fuzzy Techniques for Designing New Human Centered Products

Directory of Open Access Journals (Sweden)

Y. Zhu

2010-10-01

Full Text Available Fabric selection plays an important role in fashion garment design. Designers often use both physical and normalized linguistic criteria for fabric selection. Perception and preference of consumers in their specific sociocultural context, expressed by fashion themes or emotional linguistic criteria, affect greatly new fashion product design. Modeling the relationship between linguistic design criteria and fashion themes of a brand image perceived by consumers becomes thus significant. For setting up this model, we first use fuzzy relations and correlation techniques to select the most relevant linguistic design criteria of fabric hand for each specific fashion theme. The selected criteria can then effectively reduce the complexity of the model and interpret consumer perception of fabrics. Finally, we use a weighted aggregation operator to predict the similarity degree between any new product and fashion themes. Compared with other models, the proposed method is more robust and easier to be interpreted with real data collected for design of senior T-shirt fabrics.

How to Mitigate Theme Park Crowding? A Prospective Coordination Approach

Yuguo Yuan

2018-01-01

Full Text Available Crowding is a key factor in tourists’ experience in theme parks, and mitigating crowding makes parks more competitive. This study examines how to effectively mitigate crowding in theme parks. First, a Markov-based method is developed to predict the spatial-temporal distribution of tourists in the park. Then, a prospective coordination approach based on the tourist distribution prediction is proposed. To evaluate the performance of this approach, an experiment is constructed using an agent-based simulation platform. The results indicate that the proposed method significantly outperforms existing methods. Furthermore, we conduct two experiments and, based on the results, offer several recommendations for crowd management.

Normative study of theme identifiability: Instructions with and without explanation of the false memory effect.

Beato, Maria Soledad; Cadavid, Sara

2016-12-01

False-memory illusions have been widely studied using the Deese/Roediger-McDermott paradigm (DRM). In this paradigm, words semantically related to a single nonpresented critical word are studied. In a later memory test, critical words are often falsely recalled and recognized. The present normative study was conducted to measure the theme identifiability of 60 associative word lists in Spanish that include six words (e.g., stove, coat, blanket, scarf, chill, and bonnet) that are simultaneously associated with three critical words (e.g., HEAT, COLD, and WINTER; Beato & Díez, Psicothema, 26, 457-463, 2011). Different levels of backward associative strength were used in the construction of the DRM lists. In addition, we used two types of instructions to obtain theme identifiability. In the without-explanation condition, traditional instructions were used, requesting participants to write the theme list. In the with-explanation condition, the false-memory effect and how the lists were built were explained, and an example of a DRM list and critical words was shown. Participants then had to discover the critical words. The results showed that all lists produced theme identifiability. Moreover, some lists had a higher theme identifiability rate (e.g., 61 % for the critical words LOVE, BOYFRIEND, COUPLE) than others (e.g., 24 % for CITY, PLACE, VILLAGE). After comparing the theme identifiabilities in the different conditions, the results indicated higher theme identifiability when the false-memory effect was explained than without such an explanation. Overall, these new normative data provide a useful tool for those experiments that, for example, aim to analyze the wide differences observed in false memory with DRM lists and the role of theme identifiability.

On The Fabrication of Cultural Memory: History Theme Malls in Dubai

Directory of Open Access Journals (Sweden)

John Biln

2016-06-01

Full Text Available Dubai, one of the most mobile cities in the world, is rapidly cementing its image as a global city and icon of Islamic tolerance. Dubai’s economic opportunities, relative safety and geographic centrality in the heart of the Middle East make it attractive to a wide range of economic and political migrants from across the region. This article asks how a city which is overwhelmingly populated by members of a highly mobile and diverse non-citizen workforce could construct a plausible sense of collective memory, a fundamental requirement for any meaningful social cohesion. In considering this question, the article reviews two well-known history-themed commercial centers, Ibn Batutta Mall and the Khan Murjan in Wafi Mall. Each of these emphasize Arab-Islamic cultural heritage and the region’s long history of trade and transit. Both malls highlight culturally significant journeys documented in historical manuscripts. The article concludes that in constructing a complex experience which maps immediate spatial movement onto well-known travel narratives, the Ibn Battuta and Khan Murjan centers provide scaffolds for a cultural memory essentially “made to order” for a population who share, if little else, a profound sense of dislocation, flow and perpetual movement.

Holocene climate variability in arid Central Asia as revealed from high-resolution sedimentological and geochemical analyses of laminated sediments from Lake Chatyr Kol (Central Tian Shan, Kyrgyzstan)

Science.gov (United States)

Lauterbach, S.; Plessen, B.; Dulski, P.; Mingram, J.; Prasad, S.

2013-12-01

A pronounced trend from a predominantly wet climate during the early Holocene towards significantly drier conditions since the mid-Holocene, mainly attributed to the weakening of the Asian summer monsoon (ASM), is documented in numerous palaeoclimate records from the monsoon-influenced parts of Asia, e.g. the Tibetan Plateau and north- and southeastern China. In contrast, climate in the adjacent regions of mid-latitude arid Central Asia, located north and northwest of the Tibetan Plateau, is supposed to have been characterized by pronounced dry conditions during the early Holocene, wet conditions during the mid-Holocene and a rather moderate drying during the late Holocene, which is mainly attributed to the complex interplay between the mid-latitude Westerlies and the ASM. However, although mid-latitude Central Asia thus might represent a key region for the understanding of teleconnections between the ASM system and the Westerlies, knowledge about past climate development in this region is still ambiguous due to the limited number of high-resolution palaeoclimate records. Hence, new well-dated and highly resolved palaeoclimate records from this region are expected to provide important information about spatio-temporal changes in the regional interplay between Westerlies and ASM and thus aid the understanding of global climate teleconnections. As a part of the project CADY (Central Asian Climate Dynamics), aiming at reconstructing past climatic and hydrological variability in Central Asia, a sediment core of about 6.25 m length has been recovered from alpine Lake Chatyr Kol (40°36' N, 75°14' E, 3530 m a. s. l., surface area ~170 km2, maximum depth ~20 m), located in the Central Tian Shan of Kyrgyzstan. Sediment microfacies analysis on large-scale petrographic thin sections reveals continuously sub-mm scale laminated sediments throughout the record except for the uppermost ca. 60 cm.

2017-06-01

Full Text Available Theme-based language teaching under Content-Based Instruction (CBI is a pedagogical approach that emphasizes learning professional content along with language skills. This paper reports a case study on the impacts of a theme-based advanced Chinese intensive program in a university setting. It begins with a review of CBI and its theme-based approach and then discusses the program design, curriculum development, and instructional practice of the program. The impacts of the theme-based approach are examined based on the pre- and post-proficiency test results, learners’ self-reported surveys on the themes and topics, and the reading strategies covered in the program. Qualitative analysis of learners’ self-reflections and program evaluations is also presented. Based on the evidence collected, this paper argues that the theme-based model has positive impacts on improving language proficiency, preparing for academic and professional language use, cultivating strategic language learners, and revitalizing Chinese teaching at the superior level.

The use of biblical themes in the debate concerning the xenophobic attacks in South Africa

Zorodzai Dube

2015-03-01

Full Text Available The study draws from the ideas of J�rgen Habermas, Daniel Trotter and Christian Fuchs, Zizi Papacharissis, Yochai Benkler and Christian Fuchs to investigate the use of social media as a platform to express ideas against xenophobic-related attacks in South Africa (April 2015�May 2015. The data was collected from twitter, YouTube and Facebook. Most views came from the Facebook platform called �Stop xenophobia�. Using ATLAS.ti, software for qualitative research, the data was coded into interpretive variables or categories. The results show that themes such as hospitality, morality, creation and ethics received highest frequency as reasons to condemn xenophobia. The research further reveals that the social media data is much candid in comparison to state controlled media, where views and ideas were censored to protect the economic and public image of the country. Unlike the controlled government outlets which focus on the possible correlation between xenophobic attacks to economic outlook, the social media focuses on moral and ethical issues � issues that define our collective as human beings and tackles xenophobia from the perspective of ethics and shared human values.Intradisciplinary and/or interdisciplinary implications: This study is interdisciplinary in nature due to the use of theories in media studies and social sciences to investigate the use of biblical themes in the fight against xenophobia.

“My Silk Road to You”: Re-imagining routes, roads, and geography in contemporary art of “Central Asia”

Directory of Open Access Journals (Sweden)

Diana T. Kudaibergenova

2017-01-01

Full Text Available This paper re-focuses the Silk Road discussions from the position of contemporary art in Central Asian region. Since the late 1980s contemporary art in Central Asia boomed and it eventually became an alternative public space for the discussion of cultural transformations, social and global processes and problems that local societies faced. Initially the questions raised by many artists concerned issues of lost identity and lost heritage during the period of Soviet domination in the region. Different artists started re-imagining the concept of the Self in their works and criticising the old rigid approaches to geography, history and mobility. Nomadic heritage became one of the central themes in contemporary art of Central Asia in the 1990s. Artists started experimenting with symbols of mobility, fluid borders and imagined geography of the “magic steppe” (see Kudaibergenova 2017, “Punk Shamanism”. Contemporary art in Central Asia continues to serve as a space for social critique and a space for search and re-conceptualisation of new fluid identities, geographies and region's place on the world map. In this paper I critically evaluate three themes connected to the symbolism of Silk Road heritage that many artists engage with – imagined geography, routes, roads and mobility. All three themes are present in the selected case studies of Gulnara Kasmalieva's and Muratbek Djumaliev's TransSiberian Amazons (2005 and A New Silk Road: Algorithm of Survival and Hope (2007 multi-channel video art, Victor and Elena Vorobievs' (NonSilk Road (2006 performance and photography, Almagul Menlibayeva's My Silk Road to You video-art and photography (2010–2011, Yerbossyn Meldibekov's series on imagining Central Asia and the Mountains of Revolution (2012–2015, and Syrlybek Bekbotaev's Kyrgyz Pass installation (2014–2015 as well as Defenders of Issyk Kul (2014.

Integrated in silico Analyses of Regulatory and Metabolic Networks of Synechococcus sp. PCC 7002 Reveal Relationships between Gene Centrality and Essentiality

Directory of Open Access Journals (Sweden)

Hyun-Seob Song

2015-03-01

Full Text Available Cyanobacteria dynamically relay environmental inputs to intracellular adaptations through a coordinated adjustment of photosynthetic efficiency and carbon processing rates. The output of such adaptations is reflected through changes in transcriptional patterns and metabolic flux distributions that ultimately define growth strategy. To address interrelationships between metabolism and regulation, we performed integrative analyses of metabolic and gene co-expression networks in a model cyanobacterium, Synechococcus sp. PCC 7002. Centrality analyses using the gene co-expression network identified a set of key genes, which were defined here as “topologically important.” Parallel in silico gene knock-out simulations, using the genome-scale metabolic network, classified what we termed as “functionally important” genes, deletion of which affected growth or metabolism. A strong positive correlation was observed between topologically and functionally important genes. Functionally important genes exhibited variable levels of topological centrality; however, the majority of topologically central genes were found to be functionally essential for growth. Subsequent functional enrichment analysis revealed that both functionally and topologically important genes in Synechococcus sp. PCC 7002 are predominantly associated with translation and energy metabolism, two cellular processes critical for growth. This research demonstrates how synergistic network-level analyses can be used for reconciliation of metabolic and gene expression data to uncover fundamental biological principles.

Qualitative research on trainee well-being can add nuance to the understanding of propagators of burnout, and the role for interventions aimed at supporting well-being. This qualitative study was conducted to identify (i) situations and environments that cause stress for trainees, (ii) stress-reducing activities that trainees utilize, and (iii) whether trainees who report distress (high burnout and depression scores) describe different stressors and relaxation factors than those who do not. The study was conducted with a convenience sample of first-year medicine and psychiatry residents at a large urban teaching hospital. Participants were asked to complete electronic stress and relaxation diaries daily for 1 week. Diary entries were coded for recurrent themes. Participants were screened for burnout and depression. Codes were compared by subgroup based on baseline burnout and depression status to elucidate if specific themes emerged in these subgroups. Study sample included 51 interns. Sixteen (16/50, 32%) screened positive for burnout and three (3/50, 14%) had a positive depression screen. The most common stressors related to aspects of the learning environment, compounded by feeling under-equipped, overwhelmed, or out of time. The majority of relaxation activities involved social connection, food, other comforts, and occurred outside of the hospital environment. This study reveals that interns (regardless of burnout or depression screen) identify stressors that derive primarily from organizational, interpersonal, and cultural experiences of the learning environment; whereas relaxation themes are diversely represented across realms (home, leisure, social, health), though emphasize activities that occur outside of the work place.

The place of the clock in pediatric advice: rationales, cultural themes, and impediments to breastfeeding.

Science.gov (United States)

Millard, A V

1990-01-01

This analysis treats the U.S. medical literature as evidence concerning the formal system of knowledge in allopathic medicine. An examination of pediatric advice on breastfeeding reveals the logic of medical reasoning, the use of scientific rationales, and the intrusion of specific cultural themes. The corpus of data includes works of 18 authors published in 36 volumes from 1897 to 1987, 27 volumes being editions of two major pediatric textbooks. All sources advocate breastfeeding but the detailed advice on how to carry out the process actually tends to undermine it. Moreover, the clock has provided the main frame of reference, creating regimentation reminiscent of factory work, segmenting breastfeeding into a series of steps, and emphasizing efficiency in time and motion. Feeding schedules were advocated in former decades as a matter of discipline for the infant, but nowadays they are viewed as biologically innate to normal infants and to breast milk production. The literature manifests responses over the century to behavioral, biochemical and physiological studies; however, except possibly for one textbook, no thorough rethinking has occurred. Sources of the 1980s continue to focus on the tempo of feeding as a major concern. Cultural themes besides the factory model of breastfeeding include the extension of professional advice to family matters, the subordination of lay women to professional expertise, mistrust of women's bodily signals including the let-down reflex in determining the timing of feedings, mistrust of signals from infants as well, and a professional ideal of flexible advice coupled with rigid limits concerning schedules. The literature interweaves the cultural themes with rationales based on physiological studies in support of specific regimens in breastfeeding, and the relegation of control in breastfeeding to medical experts denies the validity of mutual bodily and emotional responses within the mother-infant dyad. Pediatric authorities thus

Since the discovery of superluminous supernovae (SLSNe) in the last decade, it has been known that these events exhibit bluer spectral energy distributions than other supernova subtypes, with significant output in the ultraviolet. However, the event Gaia16apd seems to outshine even the other SLSNe at rest-frame wavelengths below ∼3000 Å. Yan et al. have recently presented HST UV spectra and attributed the UV flux to low iron-group abundance in the outer ejecta, and hence reduced line blanketing. Here, we present UV and optical light curves over a longer baseline in time, revealing a rapid decline at UV wavelengths despite a typical optical evolution. Combining the published UV spectra with our own optical data, we demonstrate that Gaia16apd has a much hotter continuum than virtually any SLSN at maximum light, but it cools rapidly thereafter and is indistinguishable from the others by ∼10–15 days after peak. Comparing the equivalent widths of UV absorption lines with those of other events, we show that the excess UV continuum is a result of a more powerful central power source, rather than a lack of UV absorption relative to other SLSNe or an additional component from interaction with the surrounding medium. These findings strongly support the central-engine hypothesis for hydrogen-poor SLSNe. An explosion ejecting M {sub ej} = 4.8(0.2/ κ ) M {sub ⊙}, where κ is the opacity in cm{sup 2} g{sup −1}, and forming a magnetar with spin period P = 2 ms, and B = 2 × 10{sup 14} G (lower than other SLSNe with comparable rise times) can consistently explain the light curve evolution and high temperature at peak. The host metallicity, Z = 0.18 Z {sub ⊙}, is comparable to other SLSNe.

Models of advertising response implicitly assume that the entire advertising budget is spent on disseminating one message. In practice, managers use different themes of advertising (for example, price advertisements versus product advertisements) and within each theme they employ different versions of an advertisement. In this study, we evaluate the dynamic effects of different themes of advertising that have been employed in a campaign. We develop a model that jointly considers the effects o...

Influence of memory theme and posttraumatic stress disorder on memory specificity in British and Iranian trauma survivors.

Science.gov (United States)

Jobson, Laura; Cheraghi, Sepideh

2016-09-01

This study investigated the influence of culture, memory theme and posttraumatic stress disorder (PTSD) on autobiographical memory specificity in Iranian and British trauma survivors. Participants completed the Autobiographical Memory Test and PTSD Diagnostic Scale. The results indicated that the British group provided significantly more personal-themed memories than the Iranian group, while the Iranian group provided significantly more social-themed memories than the British group. The British group also provided a significantly greater proportion of specific personal-themed and social-themed memories than the Iranian group. Overall, in both cultural groups memory specificity was found to be significantly correlated with PTSD symptoms. These findings provide further evidence that regardless of memory theme, specificity of autobiographical memories function to differentiate the self from others and reaffirm the independent self. They also further highlight that pan-culturally an overgeneral retrieval style may be employed by those with PTSD symptoms.

2016-07-01

Negative perceptions of self and others have lately become one of the criteria for Posttraumatic Stress Disorder (PTSD) among adults and adolescents. Drawing from theories of mental representations in psychopathology, this study examined self-reported negative cognitions, self and parental representations, and relationship themes among adolescents with and without PTSD. Thirty one adolescents with PTSD (11 boys, mean age = 14.06, SD = 2.24) were matched with 29 adolescents who had no psychiatric diagnosis (11 boys, mean age = 14.96, SD = 1.78). Adolescents completed self-report measures, wrote a description of self, mother and father, and were interviewed about positive and negative relationship episodes with mother, father, and peers. Adolescents with PTSD reported more self-criticism and performance evaluation than did controls. Their self-representation exhibited a lower sense of agency, which was related to structural variables (i.e., less integrative description). Although parental representations of adolescents with PTSD were not generally less benevolent or more punitive than those of controls, their relationship themes revealed a higher proportion of the wish to be distant from others. Adolescents with PTSD exhibited more passive responses and perceived more dominant or controlling responses from their parents. Findings point out to a serious impairment in representations of self and relationship patterns in adolescent PTSD.

2013-01-01

Understanding positive emotions' shared and differentiating features can yield valuable insight into the structure of positive emotion space and identify emotion states, or aspects of emotion states, that are most relevant for particular psychological processes and outcomes. We report two studies that examined core relational themes (Study 1) and expressive displays (Study 2) for eight positive emotion constructs--amusement, awe, contentment, gratitude, interest, joy, love, and pride. Across studies, all eight emotions shared one quality: high positive valence. Distinctive core relational theme and expressive display patterns were found for four emotions--amusement, awe, interest, and pride. Gratitude was associated with a distinct core relational theme but not an expressive display. Joy and love were each associated with a distinct expressive display but their core relational themes also characterised pride and gratitude, respectively. Contentment was associated with a distinct expressive display but not a core relational theme. The implications of this work for the study of positive emotion are discussed.

The past 2000 years (the "2k" interval) provides critical context for understanding recent anthropogenic forcing of the climate and provides baseline information about the characteristics of natural climate variability. It also presents opportunities to improve the interpretation of proxy observations and to evaluate the climate models used to make future projections. Phases 1 and 2 of the PAGES 2k Network focussed on building regional and global surface temperature reconstructions for terrestrial regions and the oceans, and comparing these with model simulations to identify mechanisms of climate variation on interannual to bicentennial time scales. Phase 3 was launched in May 2017 and aims to address major questions around past hydroclimate, climate processes and proxy uncertainties. Its scientific themes are: Theme 1: "Climate Variability, Modes and Mechanisms"Further understand the mechanisms driving regional climate variability and change on interannual to centennial time scales; Theme 2: "Methods and Uncertainties"Reduce uncertainties in the interpretation of observations imprinted in paleoclimatic archives by environmental sensors; Theme 3: "Proxy and Model Understanding"Identify and analyse the extent of agreement between reconstructions and climate model simulations. Research is organized as a linked network of well-defined projects, identified and led by 2k community members. The 2k projects focus on specific scientific questions aligned with Phase 3 themes, rather than being defined along regional boundaries. New 2k projects can be proposed at any time at http://www.pastglobalchanges.org/ini/wg/2k-network/projects An enduring element of PAGES 2k is a culture of collegiality, transparency, and reciprocity. Phase 3 seeks to stimulate community based projects and facilitate collaboration between researchers from different regions and career stages, drawing on the breadth and depth of the global PAGES 2k community. All PAGES 2k projects also promote best

Thirty years of artificial intelligence in medicine (AIME) conferences: A review of research themes.

Peek, Niels; Combi, Carlo; Marin, Roque; Bellazzi, Riccardo

2015-09-01

Over the past 30 years, the international conference on Artificial Intelligence in MEdicine (AIME) has been organized at different venues across Europe every 2 years, establishing a forum for scientific exchange and creating an active research community. The Artificial Intelligence in Medicine journal has published theme issues with extended versions of selected AIME papers since 1998. To review the history of AIME conferences, investigate its impact on the wider research field, and identify challenges for its future. We analyzed a total of 122 session titles to create a taxonomy of research themes and topics. We classified all 734 AIME conference papers published between 1985 and 2013 with this taxonomy. We also analyzed the citations to these conference papers and to 55 special issue papers. We identified 30 research topics across 12 themes. AIME was dominated by knowledge engineering research in its first decade, while machine learning and data mining prevailed thereafter. Together these two themes have contributed about 51% of all papers. There have been eight AIME papers that were cited at least 10 times per year since their publication. There has been a major shift from knowledge-based to data-driven methods while the interest for other research themes such as uncertainty management, image and signal processing, and natural language processing has been stable since the early 1990s. AIME papers relating to guidelines and protocols are among the most highly cited. Copyright © 2015 Elsevier B.V. All rights reserved.

Suffering Daughters and Wives. Sentimental Themes in Finnish and Nordic Realism

Directory of Open Access Journals (Sweden)

Saija Isomaa

2010-10-01

Full Text Available This article examines sentimental themes and scenarios in Nordic nineteenthcentury literature, focusing on Finnish realism. The main claim of the article is that the treatment of the Woman Question in Nordic literature is thematically connected to French sentimentalism that depicted upper-class women caught in the conflict between personal freedom and familial duties. Typical scenarios were family barrier to marriage and love triangle, in which an unhappily married woman fell in love with another man. French sentimental social novels took a stance on the position of women. Similar themes and scenarios can be found in Nordic nineteenth-century novels and plays. The ‘daughter novel’ tradition from Fredrika Bremer’s The President’s Daughters (1834 to Minna Canth’s Hanna (1886 depict the sufferings of upper-class girls in patriarchal family and society. A Doll’s House (1879 by Henrik Ibsen centers on the theme of conflicting duties, depicting the moral awakening of a doll-like wife, and Papin rouva (1893, ‘The Wife of a Clergyman’ by Juhani Aho concentrates on the sufferings and moral considerations of the unhappily married Elli. The article suggests that the sentimentalist legacy informs the Nordic nineteenth-century literature and should be taken into account in the scholarship.

Types of centredness in health care: themes and concepts.

Science.gov (United States)

Hughes, Julian C; Bamford, Claire; May, Carl

2008-12-01

For a variety of sociological reasons, different types of centredness have become important in health and social care. In trying to characterize one type of centredness, we were led to consider, at a conceptual level, the importance of the notion of centredness in general and the reasons for there being different types of centeredness. We searched the literature for papers on client-, family-, patient-, person- and relationship- centred care. We identified reviews or papers that defined or discussed the notions at a conceptual level. The reviews and papers were analyzed as text transcripts. We identified 10 themes that were common to all the types of centredness. At a conceptual level we could not identify thematic differences between the types of centredness. These findings were subjected to a philosophical critique using ideas derived from Wittgenstein. Different types of centredness are required in different contexts. The differences are justified by their practical utility. The unifying themes of centredness, however, reflect a movement in favour of increasing the social, psychological, cultural and ethical sensitivity of our human encounters.

The Concept Maps as a Didactic Resource Tool of Meaningful Learning in Astronomy Themes

Silveira, Felipa Pacífico Ribeiro de Assis; Mendonça, Conceição Aparecida Soares

2015-07-01

This article presents the results of an investigation that sought to understand the performance of the conceptual map (MC) as a teaching resource facilitator of meaningful learning of scientific concepts on astronomical themes, developed with elementary school students. The methodology employed to obtain and process the data was based on a quantitative and qualitative approach. On the quantitative level we designed a quasi-experimental research with a control group that did not use the MC and an experimental group that used the MC, both being evaluated in the beginning and end of the process. In this case, the performance of both groups is displayed in a descriptive and analytical study. In the qualitative approach, the MCs were interpreted using the structuring and assigned meanings shared by the student during his/her presentation. The results demonstrated through the improvement of qualifications that the MC made a difference in conceptual learning and in certain skills revealed by learning indicators.

Ethnicity moderates the outcomes of self-enhancement and self-improvement themes in expressive writing.

Tsai, William; Lau, Anna S; Niles, Andrea N; Coello, Jordan; Lieberman, Matthew D; Ko, Ahra C; Hur, Christopher; Stanton, Annette L

2015-10-01

The current study examined whether writing content related to self-enhancing (viz., downward social comparison and situational attributions) and self-improving (viz., upward social comparison and persistence) motivations were differentially related to expressive writing outcomes among 17 Asian American and 17 European American participants. Content analysis of the essays revealed no significant cultural group differences in the likelihood of engaging in self-enhancing versus self-improving reflections on negative personal experiences. However, cultural group differences were apparent in the relation between self-motivation processes and changes in anxiety and depressive symptoms at 3-month follow-up. Among European Americans, writing that reflected downward social comparison predicted positive outcomes, whereas persistence writing themes were related to poorer outcomes. For Asian Americans, writing about persistence was related to positive outcomes, whereas downward social comparison and situational attributions predicted poorer outcomes. Findings provide evidence suggesting culturally distinct mechanisms for the effects of expressive disclosure. (PsycINFO Database Record (c) 2015 APA, all rights reserved).

Exploratory Analysis of Marketing and Non-marketing E-cigarette Themes on Twitter.

Science.gov (United States)

Han, Sifei; Kavuluru, Ramakanth

2016-11-01

Electronic cigarettes (e-cigs) have been gaining popularity and have emerged as a controversial tobacco product since their introduction in 2007 in the U.S. The smoke-free aspect of e-cigs renders them less harmful than conventional cigarettes and is one of the main reasons for their use by people who plan to quit smoking. The US food and drug administration (FDA) has introduced new regulations early May 2016 that went into effect on August 8, 2016. Given this important context, in this paper, we report results of a project to identify current themes in e-cig tweets in terms of semantic interpretations of topics generated with topic modeling. Given marketing/advertising tweets constitute almost half of all e-cig tweets, we first build a classifier that identifies marketing and non-marketing tweets based on a hand-built dataset of 1000 tweets. After applying the classifier to a dataset of over a million tweets (collected during 4/2015 - 6/2016), we conduct a preliminary content analysis and run topic models on the two sets of tweets separately after identifying the appropriate numbers of topics using topic coherence. We interpret the results of the topic modeling process by relating topics generated to specific e-cig themes. We also report on themes identified from e-cig tweets generated at particular places (such as schools and churches) for geo-tagged tweets found in our dataset using the GeoNames API. To our knowledge, this is the first effort that employs topic modeling to identify e-cig themes in general and in the context of geo-tagged tweets tied to specific places of interest.

Integrated pathway clusters with coherent biological themes for target prioritisation.

Directory of Open Access Journals (Sweden)

Yi-An Chen

Full Text Available Prioritising candidate genes for further experimental characterisation is an essential, yet challenging task in biomedical research. One way of achieving this goal is to identify specific biological themes that are enriched within the gene set of interest to obtain insights into the biological phenomena under study. Biological pathway data have been particularly useful in identifying functional associations of genes and/or gene sets. However, biological pathway information as compiled in varied repositories often differs in scope and content, preventing a more effective and comprehensive characterisation of gene sets. Here we describe a new approach to constructing biologically coherent gene sets from pathway data in major public repositories and employing them for functional analysis of large gene sets. We first revealed significant overlaps in gene content between different pathways and then defined a clustering method based on the shared gene content and the similarity of gene overlap patterns. We established the biological relevance of the constructed pathway clusters using independent quantitative measures and we finally demonstrated the effectiveness of the constructed pathway clusters in comparative functional enrichment analysis of gene sets associated with diverse human diseases gathered from the literature. The pathway clusters and gene mappings have been integrated into the TargetMine data warehouse and are likely to provide a concise, manageable and biologically relevant means of functional analysis of gene sets and to facilitate candidate gene prioritisation.

In 1998, EDF organized a study on how to communicate on the theme of nuclear waste to help understand why communication on this theme seems to be stuck. This study has involved many psychotherapists, psychologists and physicians from different schools of thought. Afterwards a team of internal and external consultants continued the work in 1999 and explored 'the hidden aspects' of the communication that is made on nuclear waste. What are those aspects? What has to be taken into account in such a communication on a theme that is 'absorbing', 'strong', 'invisible'? How to build a more efficient and relevant communication towards the public and the ecologists? How to build a communication which opens up a dialogue and mutual understanding? The first part of this qualitative study has been devoted to interviewing the psychotherapists in a non directive way on what are the representations and beliefs about waste in general, then about nuclear waste. The second part was centered on their reactions to a pamphlet 'Nuclear waste in questions' and a video document (of a presentation of a paper given on the subject).

Therapeutic affordances of social media: emergent themes from a global online survey of people with chronic pain.

Science.gov (United States)

Merolli, Mark; Gray, Kathleen; Martin-Sanchez, Fernando

2014-12-22

Research continues to present tenuous suggestions that social media is well suited to enhance management of chronic disease and improve health outcomes. Various studies have presented qualitative reports of health outcomes from social media use and have examined discourse and communication themes occurring through different social media. However, there is an absence of published studies examining and unpacking the underlying therapeutic mechanisms driving social media's effects. This paper presents a qualitative analysis thoroughly describing what social media therapeutically affords people living with chronic pain who are self-managing their condition. From this therapeutic affordance perspective, we aim to formulate a preliminary conceptual model aimed at better understanding "how" social media can influence patient outcomes. In total, 218 people with chronic pain (PWCP) completed an online survey, investigating patient-reported outcomes (PROs) from social media use. Supplementary to quantitative data collected, participants were also given the opportunity to provide further open commentary regarding their use of social media as part of chronic pain management; 68/218 unique users (31.2%) chose to provide these free-text responses. Through thematic content analysis, 117 free-text responses regarding 10 types of social media were coded. Quotes were extracted and tabulated based on therapeutic affordances that we had previously identified. Inductive analysis was then performed to code defining language and emergent themes central to describing each affordance. Three investigators examined the responses, developed the coding scheme, and applied the coding to the data. We extracted 155 quotes from 117 free-text responses. The largest source of quotes came from social network site users (78/155, 50.3%). Analysis of component language used to describe the aforementioned affordances and emergent themes resulted in a final revision and renaming of therapeutic affordances

Rotating swings—a theme with variations

Pendrill, Ann-Marie

2016-01-01

Rotating swing rides can be found in many amusement parks, in many different versions. The ‘wave swinger’ ride, which introduces a wave motion by tilting the roof, is among the classical amusement rides that are found in many different parks, in different sizes, from a number of different makes and names, and varying thematization. The ‘StarFlyer’ is a more recent version, adding the thrill of lifting the riders 60 m or more over the ground. These rotating swing rides involve beautiful physics, often surprising, but easily observed, when brought to attention. The rides can be used for student worksheet tasks and assignments of different degrees of difficulty, across many math and physics topics. This paper presents a number of variations of student tasks relating to the theme of rotating swing rides.

Since the fire on Dealul Spirii, a real story, had been given five different interpretations by the local media, so must we understand Caragiale’s literary pieces: they have a “plot”, i.e. the society, and several “variants” (forms, i.e. the events or happenings of all kinds. As an urban writer, Caragiale was preoccupied with the town and its very life, but also with folk themes and motifs. He also described the countryside with its scenery, inns and innkeepers, the places where people used to meet and talk. Trades and their professions were presented in his sketches and stories, too

Qualitative data analysis for health services research: developing taxonomy, themes, and theory.

Science.gov (United States)

Bradley, Elizabeth H; Curry, Leslie A; Devers, Kelly J

2007-08-01

To provide practical strategies for conducting and evaluating analyses of qualitative data applicable for health services researchers. DATA SOURCES AND DESIGN: We draw on extant qualitative methodological literature to describe practical approaches to qualitative data analysis. Approaches to data analysis vary by discipline and analytic tradition; however, we focus on qualitative data analysis that has as a goal the generation of taxonomy, themes, and theory germane to health services research. We describe an approach to qualitative data analysis that applies the principles of inductive reasoning while also employing predetermined code types to guide data analysis and interpretation. These code types (conceptual, relationship, perspective, participant characteristics, and setting codes) define a structure that is appropriate for generation of taxonomy, themes, and theory. Conceptual codes and subcodes facilitate the development of taxonomies. Relationship and perspective codes facilitate the development of themes and theory. Intersectional analyses with data coded for participant characteristics and setting codes can facilitate comparative analyses. Qualitative inquiry can improve the description and explanation of complex, real-world phenomena pertinent to health services research. Greater understanding of the processes of qualitative data analysis can be helpful for health services researchers as they use these methods themselves or collaborate with qualitative researchers from a wide range of disciplines.

This paper focuses on the climate variability in central China since AD 1300, involving: (1) a well-dated, 1.5-year resolution stalagmite δ18O record from Lianhua Cave, central China (2) links of the δ18O record with regional dry-wet conditions, monsoon intensity, and temperature over eastern China (3) correlations among drought events in the Lianhua record, solar irradiation, and ENSO (El Niño-Southern Oscillation) variation. We present a highly precise, 230Th / U-dated, 1.5-year resolution δ18O record of an aragonite stalagmite (LHD1) collected from Lianhua Cave in the Wuling Mountain area of central China. The comparison of the δ18O record with the local instrumental record and historical documents indicates that (1) the stalagmite δ18O record reveals variations in the summer monsoon intensity and dry-wet conditions in the Wuling Mountain area. (2) A stronger East Asian summer monsoon (EASM) enhances the tropical monsoon trough controlled by ITCZ (Intertropical Convergence Zone), which produces higher spring quarter rainfall and isotopically light monsoonal moisture in the central China. (3) The summer quarter/spring quarter rainfall ratio in central China can be a potential indicator of the EASM strength: a lower ratio corresponds to stronger EASM and higher spring rainfall. The ratio changed from 1 after 1950, reflecting that the summer quarter rainfall of the study area became dominant under stronger influence of the Northwestern Pacific High. Eastern China temperatures varied with the solar activity, showing higher temperatures under stronger solar irradiation, which produced stronger summer monsoons. During Maunder, Dalton and 1900 sunspot minima, more severe drought events occurred, indicating a weakening of the summer monsoon when solar activity decreased on decadal timescales. On an interannual timescale, dry conditions in the study area prevailed under El Niño conditions, which is also supported by the spectrum analysis. Hence, our record

2011-12-01

Full Text Available Investments in policies for science teachers, as well as their adaptation to new realities and technologies are essential, since the teacher is the key to changing mindsets and attitudes of their students. Thus, conceptual discussions are proposed between chemistry teachers in a virtual environment on the Moodle platform on topics previously chosen by the education teacher. The objective is to analyze the process of creating meanings of participants of the forum on the theme "nature of science." It was noticed that new media can help building students' knowledge and motivate them to expand their research and scientific readings; however, rules must be preestablished so that a real interaction and mediation could occur. Initiatives like these are useful for the understanding of scientific and technical fields, and may also facilitate communication and interaction between teachers and students.

Blackstone, Craig

2018-05-10

Hereditary spastic paraplegias (HSPs) are neurologic disorders characterized by prominent lower-extremity spasticity, resulting from a length-dependent axonopathy of corticospinal upper motor neurons. They are among the most genetically-diverse neurologic disorders, with >80 distinct genetic loci and over 60 identified genes. Studies investigating the molecular pathogenesis underlying HSPs have emphasized the importance of converging cellular pathogenic themes in the most common forms of HSP, providing compelling targets for therapy. Most notably, these include organelle shaping and biogenesis as well as membrane and cargo trafficking. Published by Elsevier Ltd.

Couple-based communication interventions have beneficial effects for patients with cancer and their partners. However, few studies have targeted patients with advanced stages of disease and little is known about how best to assist couples in discussing issues related to life-limiting illness. The purpose of the present study was to identify themes couples addressed during a couple communication skills intervention, and the frequency with which they discussed issues related to end-of-life. Content analyses were conducted on recordings of 72 sessions from 12 couples facing advanced gastrointestinal (GI) cancer. Coding was based six themes identified a priori from the framework for understanding what patients and family value at end of life. The percent of couples addressing each theme was calculated to gauge level of importance and acceptability of these topics. The majority of couples addressed topics previously identified as salient at end-of-life, including clear decision making, affirmation of the whole person, pain and symptom management, contributing to others, and preparation for death. In addition, novel aspects to these themes emerged in the context of couples' conversations, illustrating the importance of the couple relationship in adjusting to life with a life-limiting illness and anticipating the transition to end-of-life. Findings suggest that couples likely would be receptive to an intervention that combines training in communication skills with guidance in focusing on issues related to life completion to assist with transitions at end of life. Such interventions might enhance both individuals' abilities to cope with illness-related symptoms and demands, enjoy the time they have together, and derive meaning from the experience.

Ahmady, Soleiman; Akbari Lakeh, Maryam

2015-01-01

The purpose of this paper is to explore themes for enhancing socially accountability in medical education. Medical education in Iran experience new challenges due to the enormous influence of changes in technology, development of new methods of teaching and learning, student requirements, patient management, financial credit constraints, and social and economic developments. For responding to these, use of strategic thinking in order to make appropriate decisions is the only solution. Strategic plans need to formulate practical guides which can help accountable to people's reasonable expectations. For this qualitative study, along with the 14(th)national conference on Medical Education in Iran, the opinions of experts were obtained during seven expert panels' group discussions, each lasting four hours and including 10 participants. Data were collected by audiotapes, which were then transcribed. Data analyzed using a thematic content analysis approach. Peer and member checking during analysis and data triangulation from other recent studies were used to increase the findings' trustworthiness. Among more than hundred meaning units groups identified the following eight main themes as affecting the social accountable medical education in Iran: organization of responsive education councils; development of community based courses; development in field training; organization of educational processes; homogeneity in educational rules and regulations; budget management, educational outcomes; educational programs in departments and groups. This study have found the main themes that might affecting social accountable medical education in Iran, where Iranian policymakers should consider those when plan to make changes in medical education and could potentially adopt the proven useful policies and strategies of other countries.

Making Sense of the Brutality of the Holocaust: Critical Themes and New Perspectives.

Miller, Eric D

2017-01-02

This article offers an analytic, integrative review of select themes associated with one of history's greatest atrocities: the Holocaust. Much of this review considers general and Holocaust-specific themes as they pertain to the nature of senseless violence and evil. The importance of having a greater understanding of the sheer brutality of violence perpetuated in the Holocaust is emphasized. As part of this discussion, considerable attention is given to how Internet-based photographs and videos from the Holocaust era can provide greater insight into understanding the evil associated with this genocide. Some consideration of the larger meaning of the Holocaust, particularly for Jews, is also examined.

George, Stephanie M; Domire, Zachary J

2017-07-01

As the reliance on computational models to inform experiments and evaluate medical devices grows, the demand for students with modeling experience will grow. In this paper, we report on the 3-yr experience of a National Science Foundation (NSF) funded Research Experiences for Undergraduates (REU) based on the theme simulations, imaging, and modeling in biomechanics. While directly applicable to REU sites, our findings also apply to those creating other types of summer undergraduate research programs. The objective of the paper is to examine if a theme of simulations, imaging, and modeling will improve students' understanding of the important topic of modeling, provide an overall positive research experience, and provide an interdisciplinary experience. The structure of the program and the evaluation plan are described. We report on the results from 25 students over three summers from 2014 to 2016. Overall, students reported significant gains in the knowledge of modeling, research process, and graduate school based on self-reported mastery levels and open-ended qualitative responses. This theme provides students with a skill set that is adaptable to other applications illustrating the interdisciplinary nature of modeling in biomechanics. Another advantage is that students may also be able to continue working on their project following the summer experience through network connections. In conclusion, we have described the successful implementation of the theme simulation, imaging, and modeling for an REU site and the overall positive response of the student participants.

McCormack, Mark; Anderson, Eric

2010-11-01

In this study, we draw on findings from one year of participant observation and 12 in-depth interviews with men in a highly-ranked English university rugby team in order to nuance theoretical understandings concerning the re-production of homosexually-themed discourse in organised sport. We use ethnographic data to theorise the complex relationship between language, homosocial masculine relationships and organised sport. In examining the political, intentional and inadvertent effects of these men's discourses, we define and discuss the notion of gay discourse as a form of heteronormativity that is dissimilar to the traditional use of homophobic discourse. Highlighting that homosexually-themed discourse is best understood as a continuum, we stress the importance of context in interpreting the meaning and explicating the effects of this kind of discourse.

Issues with data and analyses: Errors, underlying themes, and potential solutions.

Science.gov (United States)

Brown, Andrew W; Kaiser, Kathryn A; Allison, David B

2018-03-13

Some aspects of science, taken at the broadest level, are universal in empirical research. These include collecting, analyzing, and reporting data. In each of these aspects, errors can and do occur. In this work, we first discuss the importance of focusing on statistical and data errors to continually improve the practice of science. We then describe underlying themes of the types of errors and postulate contributing factors. To do so, we describe a case series of relatively severe data and statistical errors coupled with surveys of some types of errors to better characterize the magnitude, frequency, and trends. Having examined these errors, we then discuss the consequences of specific errors or classes of errors. Finally, given the extracted themes, we discuss methodological, cultural, and system-level approaches to reducing the frequency of commonly observed errors. These approaches will plausibly contribute to the self-critical, self-correcting, ever-evolving practice of science, and ultimately to furthering knowledge.

Therapeutic Affordances of Social Media: Emergent Themes From a Global Online Survey of People With Chronic Pain

Science.gov (United States)

Gray, Kathleen; Martin-Sanchez, Fernando

2014-01-01

Background Research continues to present tenuous suggestions that social media is well suited to enhance management of chronic disease and improve health outcomes. Various studies have presented qualitative reports of health outcomes from social media use and have examined discourse and communication themes occurring through different social media. However, there is an absence of published studies examining and unpacking the underlying therapeutic mechanisms driving social media’s effects. Objective This paper presents a qualitative analysis thoroughly describing what social media therapeutically affords people living with chronic pain who are self-managing their condition. From this therapeutic affordance perspective, we aim to formulate a preliminary conceptual model aimed at better understanding "how" social media can influence patient outcomes. Methods In total, 218 people with chronic pain (PWCP) completed an online survey, investigating patient-reported outcomes (PROs) from social media use. Supplementary to quantitative data collected, participants were also given the opportunity to provide further open commentary regarding their use of social media as part of chronic pain management; 68/218 unique users (31.2%) chose to provide these free-text responses. Through thematic content analysis, 117 free-text responses regarding 10 types of social media were coded. Quotes were extracted and tabulated based on therapeutic affordances that we had previously identified. Inductive analysis was then performed to code defining language and emergent themes central to describing each affordance. Three investigators examined the responses, developed the coding scheme, and applied the coding to the data. Results We extracted 155 quotes from 117 free-text responses. The largest source of quotes came from social network site users (78/155, 50.3%). Analysis of component language used to describe the aforementioned affordances and emergent themes resulted in a final revision

Jurandir Peinado

2016-01-01

Full Text Available An article published at Revista de Gestão (REGE, an academic journal by the University of Sao Paulo, in 2013, proposed the mapping of Operations Management themes based on the editorial space provided in major journals and conf erence proceedings in the area. Based on such proposal, the current study conducted a survey to capture the importance assigned to those themes by researchers, lecturers and practitioners and how they categorized the themes into broader groupings. A factor analysis was performed with the data collected by means of the survey and several statistical tests were also carried out in order to assess the strength of the constructs and to confirm the dimensions proposed in the referred mapping of Operations Manage ment themes, allowing for its refinement. The factor analysis resulted in nine factors, seven of which very closely resemble the constructs presented in the previous paper. Thus, the results obtained herein confirm most of the previously obtained mapping, providing a further step in the discussion of the themes that are relevant to the area of Operations Management

Beversdorf, David Q; White, Dawn M; Chever, Daquesha C; Hughes, John D; Bornstein, Robert A

2002-12-20

Situational stressors and anxiety impede performance on creativity tests requiring cognitive flexibility. Preliminary research revealed better performance on a task requiring cognitive flexibility, the anagram task, after propranolol (beta-adrenergic antagonist) than after ephedrine (beta-adrenergic agonist). However, propranolol and ephedrine have both peripheral and central beta-adrenergic effects. In order to determine whether noradrenergic modulation of cognitive flexibility is a centrally or peripherally mediated phenomenon, we compared the effects of propranolol (peripheral and central beta-blocker), nadolol (peripheral beta-blocker), and placebo on anagram task performance. Solution latency scores for each subject were compared across the drug conditions. Anagram solution latency scores after propranolol were significantly lower than after nadolol. This suggests a centrally mediated modulatory influence of the noradrenergic system on cognitive flexibility.

GFT centrality: A new node importance measure for complex networks

Science.gov (United States)

Singh, Rahul; Chakraborty, Abhishek; Manoj, B. S.

2017-12-01

Identifying central nodes is very crucial to design efficient communication networks or to recognize key individuals of a social network. In this paper, we introduce Graph Fourier Transform Centrality (GFT-C), a metric that incorporates local as well as global characteristics of a node, to quantify the importance of a node in a complex network. GFT-C of a reference node in a network is estimated from the GFT coefficients derived from the importance signal of the reference node. Our study reveals the superiority of GFT-C over traditional centralities such as degree centrality, betweenness centrality, closeness centrality, eigenvector centrality, and Google PageRank centrality, in the context of various arbitrary and real-world networks with different degree-degree correlations.

Adults Contemplating University Study at a Distance: Issues, themes and concerns

Directory of Open Access Journals (Sweden)

Chris Morgan

2003-04-01

Full Text Available This study identifies and explores a range of themes, issues and questions that commonly confront adults contemplating enrolment in university, and why they persist. The study focuses particularly on issues facing prospective adult distance education learners. From a range of interviews, six themes were identified including fears, motivation, support from home, academic preparedness, suitability of programs, and identity change.It is argued that the more effective we become at information provision, guidance and preparation of adult pre-entry open and distance learners, the more likely students will experience a smooth transition to study, thus improving both student satisfaction and retention rates. Successful intervention with prospective distance education learners at this early point should aim to assist the process of informed decision making, which could result equally in an individual deciding not to pursue university study. The findings in this study should be particularly useful for those academics, course advisors, student counsellors, teachers in preparatory programs, and university information and support officers, and others who provide adult distance students, with pre-enrolment information and advice.

Full Text Available The text discusses the metropolitan theme from the perspective of productive restructuring, especially the spatial transformations and the reconfiguration of the central area of Fortaleza. The focus is placed upon the comprehension of the social-spatial processes in their configuration with fragments, residues and new centralities, which testify to the process of production of the city in the light of property restructuring as a strategy for the reproduction of capital. The hegemony of financial capital and of the national and transnational construction companies reinforces mechanisms of social-spatial reproduction altering the urban structure and the expansion of the urban sprawl. This text confirms the significance and importance of the condominiums, walled properties and shopping malls which alter the price of urban land and modify, above all, the use of the soil.

A Thematic Analysis of Online Discussion Boards for Brachial Plexus Injury.

Science.gov (United States)

Morris, Marie T; Daluiski, Aaron; Dy, Christopher J

2016-08-01

Patients with brachial plexus injury (BPI) and their family members contribute to Internet discussion groups dedicated to BPI. We hypothesized that a thematic analysis of posts from BPI Internet discussion groups would reveal common themes related to the BPI patient experience, providing topics for patient education and counseling. Internet discussion boards were identified using the search term "brachial plexus injury support group" in Google, Bing, and Yahoo! search engines. Two discussion boards had substantially more posts than other Web sites and were chosen for analyses. Posts from January 1, 2015, through January 1, 2016, were examined. Using an iterative and established process, 2 investigators (M.T.M. and C.J.D) independently analyzed each post using thematic analysis in 3 steps (open coding, axial coding, and selective coding) to determine common themes. In this process, each post was reviewed 3 times. A total of 328 posts from the 2 leading discussion boards were analyzed. Investigators reached a consensus on themes for all posts. One central theme focused on emotional aspects of BPI. Four other central themes regarding information support were identified: BPI disease, BPI treatment, recovery after BPI treatment, and process of seeking care for BPI. Examination of posts on Internet support groups for BPI revealed recurring concerns, questions, and opinions of patients and their family members. The most common themes related to disease information, treatment, recovery, and the emotional element of BPI. These findings provide a helpful starting point in refining topics for patient education and support that are targeted on patients' interests and concerns.

But the clinical and radiological characteristics of central ADCs remain unclear. In this study, we compared the clinical and radiological characteristics of central ADCs with those of small cell lung cancers (SCLCs and squamous cell carcinomas (SQCCs and investigated the impact of these characteristics on patients’ treatment response. Patients and methods: The medical records of 302 consecutive patients with central lung cancer from July 2014 to September 2016 were retrospectively reviewed. There were 99 patients with ADC, 95 with SQCC and 108 with SCLC. Computed tomography images were interpreted by two radiologists. Treatment response was determined by Response Evaluation Criteria In Solid Tumors 1.1. Results: Univariate analyses found that younger age, female sex, no history of smoking, higher levels of carcinoembryonic antigen (CEA, contralateral hilum lymphadenopathy, contralateral lung metastasis, pleural nodules and pleural metastasis to the interlobular fissure were significantly correlated with central ADC. Multivariate logistic regression analyses revealed that compared with central SQCC, female sex, younger age, no history of smoking, higher levels of CEA and contralateral hilum lymphadenopathy were the significantly independent indicators of central pulmonary ADC. Furthermore, compared with central SCLC, younger age, higher levels of CEA and cytokeratin 19 fragment (Cyfra21-1, lower

Shewanella spp. are a group of facultative anaerobic bacteria widely distributed in marine and fresh-water environments. In this study, we profiled the central metabolic fluxes of eight recently sequenced Shewanella species grown under the same condition in minimal med-ium with [3-13C] lactate. Although the tested Shewanella species had slightly different growth rates (0.23-0.29 h31) and produced different amounts of acetate and pyruvate during early exponential growth (pseudo-steady state), the relative intracellular metabolic flux distributions were remarkably similar. This result indicates that Shewanella species share similar regulation in regard to central carbon metabolic fluxes under steady growth conditions: the maintenance of metabolic robustness is not only evident in a single species under genetic perturbations (Fischer and Sauer, 2005; Nat Genet 37(6):636-640), but also observed through evolutionary related microbial species. This remarkable conservation of relative flux profiles through phylogenetic differences prompts us to introduce the concept of metabotype as an alternative scheme to classify microbial fluxomics. On the other hand, Shewanella spp. display flexibility in the relative flux profiles when switching their metabolism from consuming lactate to consuming pyruvate and acetate.

Highlight: this paper focuses on the climate variability in central China since 1300 AD, involving: 1. A well-dated, 1.5 year resolution stalagmite δ18O record from Lianhua Cave, central China; 2. Links of the δ18O record with regional dry-wet condition, monsoon intensity, and temperature over eastern China; 3. Correlations among drought events in the Lianhua record, solar irradiation, and ENSO index. We present a highly precisely 230Th/U dated, 1.5 year resolution δ18O record of an aragonite stalagmite (LHD1) collected from Lianhua Cave in Wuling mountain area of central China. The comparison of the δ18O record with the local instrumental record and historical documents exhibits at least 15 drought events in the Wuling mountain and adjacent areas during the Little Ice Age, in which some of them were corresponding to megadrought events in the broad Asian monsoonal region of China. Thus, the stalagmite δ18O record reveals variations in the summer monsoon precipitation and dry-wet condition in Wuling mountain area. The eastern China temperature varied with the solar activity, showing higher temperature under stronger solar irradiation which produces stronger summer monsoon. During Maunder, Dalton and 1900 sunspot minima, more severe drought events occurred, indicating weakening of the summer monsoon when solar activity decreased on decadal time scales. On interannual time scale, dry conditions in the studying area were prevailing under El Niño condition, which is also supported by the spectrum analysis. Hence, our record illustrates the linkage of Asian summer monsoon precipitation to solar irradiation and ENSO: wetter condition under stronger summer monsoon during warm periods and vice versa; During cold periods, the Walker circulation will shift toward central Pacific under El Niño condition, resulting further weakening of Asian summer monsoon. However, the δ18O of LHD1 record is positively correlated with temperature after ~1940 AD which is opposite to the

Smoking prevalence is very high among lesbian, gay, bisexual, transgendered and queer (LGBTQ+) youth and young adults (YYA) compared to non-LGBTQ+ YYA. A knowledge gap exists on culturally appropriate and effective prevention and cessation efforts for members of this diverse community, as limited interventions have been developed with and for this population, and there are very few studies determining the impact of these interventions. This study identifies the most salient elements of LGBTQ+ cessation and prevention interventions from the perspective of LGBTQ+ YYA. Three descriptions of interventions tailored for LGBTQ+ YYA (group cessation counselling, social marketing, and a mobile phone app with social media incorporated), were shared with LGBTQ+ YYA via 24 focus groups with 204 participants in Toronto and Ottawa, Canada. Open-ended questions focused on their feelings, likes and dislikes, and concerns about the culturally modified intervention descriptions. Framework analysis was used to identify overarching themes across all three intervention descriptions. The data revealed eight overarching themes across all three intervention descriptions. Smoking cessation and prevention interventions should have the following key attributes: 1) be LGBTQ+ - specific; 2) be accessible in terms of location, time, availability, and cost; 3) be inclusive, relatable, and highlight diversity; 4) incorporate LGBTQ+ peer support and counselling services; 5) integrate other activities beyond smoking; 6) be positive, motivational, uplifting, and empowering; 7) provide concrete coping mechanisms; and 8) integrate rewards and incentives. LGBTQ+ YYA focus group participants expressed a desire for an intervention that can incorporate these key elements. The mobile phone app and social media campaign were noted as potential interventions that could include all the essential elements.

Geophysical data collected along 29 traverses across the central block of Yucca Mountain in southwest Nevada reveal anomalies associated with known fault sand indicate a number of possible concealed faults beneath the eastern flank of Yucca Mountain. Geophysical interpretations indicate that Midway Valley is characterized by several known and previously unknown faults, that the existence of the Yucca Wash fault is equivocal, and that the central part of the eastern flank of Yucca Mountain is characterized by numerous low-amplitude anomalies that probably reflect numerous small-scale faults. Gravity and magnetic data also reveal several large-amplitude anomalies that reflect larger-scale faulting along the margins of the central block

Ten-a affects the fusion of central complex primordia in Drosophila.

Directory of Open Access Journals (Sweden)

Xuebo Cheng

Full Text Available The central complex of Drosophila melanogaster plays important functions in various behaviors, such as visual and olfactory memory, visual orientation, sleep, and movement control. However little is known about the genes regulating the development of the central complex. Here we report that a mutant gene affecting central complex morphology, cbd (central brain defect, was mapped to ten-a, a type II trans-membrane protein coding gene. Down-regulation of ten-a in pan-neural cells contributed to abnormal morphology of central complex. Over-expression of ten-a by C767-Gal4 was able to partially restore the abnormal central complex morphology in the cbd mutant. Tracking the development of FB primordia revealed that C767-Gal4 labeled interhemispheric junction that separated fan-shaped body precursors at larval stage withdrew to allow the fusion of the precursors. While the C767-Gal4 labeled structure did not withdraw properly and detached from FB primordia, the two fan-shaped body precursors failed to fuse in the cbd mutant. We propose that the withdrawal of C767-Gal4 labeled structure is related to the formation of the fan-shaped body. Our result revealed the function of ten-a in central brain development, and possible cellular mechanism underlying Drosophila fan-shaped body formation.

The role of tobacco advertising and promotion: themes employed in litigation by tobacco industry witnesses.

Goldberg, Marvin E; Davis, Ronald M; O'Keefe, Anne Marie

2006-12-01

To identify key themes related to tobacco advertising and promotion in testimony provided by tobacco industry-affiliated witnesses in tobacco litigation, and to present countervailing evidence and arguments. Themes in industry testimony were identified by review of transcripts of testimony in the Tobacco Deposition and Trial Testimony Archive (http://tobaccodocuments.org/datta) from a sample of defence witnesses, including three academic expert witnesses, six senior executives of tobacco companies, and one industry advertising consultant. Counterarguments to the themes embodied in defence testimony were based on information from peer-reviewed literature, advertising trade publications, government reports, tobacco industry documents, and testimony provided by expert witnesses testifying for plaintiffs. Five major themes employed by defence witnesses were identified: (1) tobacco advertising has a relatively weak "share of voice" in the marketing environment and is a weak force in affecting smoking behaviour; (2) tobacco advertising and promotion do not create new smokers, expand markets, or increase total tobacco consumption; (3) the tobacco industry does not target, study, or track youth smoking; (4) tobacco advertising and promotion do not cause smoking initiation by youth; and (5) tobacco companies and the industry adhere closely to relevant laws, regulations, and industry voluntary codes. Substantial evidence exists in rebuttal to these arguments. Tobacco industry-affiliated witnesses have marshalled many arguments to deny the adverse effects of tobacco marketing activities and to portray tobacco companies as responsible corporate citizens. Effective rebuttals to these arguments exist, and plaintiffs' attorneys have, with varying degrees of success, presented them to judges and juries.

2009-08-01

The study explored the influence of university-based teacher education courses on pre-service middle and high school teachers’ experiences with multicultural themes in a secondary science alternative certification program. Eight participants ( N = 8), six women and two men, volunteered to be a part of the study that took place over a period of four semesters. Qualitative data was collected, coded and analyzed to make meaning of the participants’ experiences. Data comprised of participants’ reflective journals, personal and group interviews, and classroom observations done in middle school practicum and high school student teaching placements. The findings indicated that while the participants became more familiar with the themes of multicultural education, many did not demonstrate fluency with these themes and struggled with balancing their responsibilities as a science teacher and a culturally competent teacher.

Various studies on ancient DNA have attempted to reconstruct population movement in Asia, with much interest focused on determining the arrival of European lineages in ancient East Asia. Here, we discuss our analysis of the mitochondrial DNA of human remains excavated from the Yu Hong tomb in Taiyuan, China, dated 1400 years ago. The burial style of this tomb is characteristic of Central Asia at that time. Our analysis shows that Yu Hong belonged to the haplogroup U5, one of the oldest western Eurasian-specific haplogroups, while his wife can be classified as haplogroup G, the type prevalent in East Asia. Our findings show that this man with European lineage arrived in Taiyuan approximately 1400 years ago, and most probably married a local woman. Haplogroup U5 was the first west Eurasian-specific lineage to be found in the central part of ancient China, and Taiyuan may be the easternmost location of the discovered remains of European lineage in ancient China.

2017-05-23

People have more visual experiences than ever before, and the same is true for situations in medicine. More mature films and television shows with a medical theme have been available over the past 20 years. In mainland China, the TV series "Angel Heart" has generated a wave of universal concern since it truly depicts the work of health care workers and it reflects the sharp distinction between doctors and patients to a certain extent. Riding this wave, many medical documentaries like The Human World have also been launched in China and have garnered sizable audiences. Such films and television shows with a medical theme strive to depict the lives of ordinary people. When watching these medical documentaries, audiences are able to better comprehend the work of health care workers in light of their life experiences and feelings towards current society. Audiences can gain a profound understanding of the medical humanities through films and television shows with a medical theme. We look forward to more such films and television shows with a medical theme that depict "hospitals-the realest place" on camera. Films and television shows with a medical theme can serve as a storytelling medium to accelerate the spread of medical humanities and to promote harmony among doctors, patients, and the public.

Central powering of the largest Lyman-α nebula is revealed by polarized radiation.

Science.gov (United States)

Hayes, Matthew; Scarlata, Claudia; Siana, Brian

2011-08-17

High-redshift Lyman-α (Lyα) blobs are extended, luminous but rare structures that seem to be associated with the highest peaks in the matter density of the Universe. Their energy output and morphology are similar to those of powerful radio galaxies, but the source of the luminosity is unclear. Some blobs are associated with ultraviolet or infrared bright galaxies, suggesting an extreme starburst event or accretion onto a central black hole. Another possibility is gas that is shock-excited by supernovae. But not all blobs are associated with galaxies, and these ones may instead be heated by gas falling into a dark-matter halo. The polarization of the Lyα emission can in principle distinguish between these options, but a previous attempt to detect this signature returned a null detection. Here we report observations of polarized Lyα from the blob LAB1 (ref. 2). Although the central region shows no measurable polarization, the polarized fraction (P) increases to ∼20 per cent at a radius of 45 kiloparsecs, forming an almost complete polarized ring. The detection of polarized radiation is inconsistent with the in situ production of Lyα photons, and we conclude that they must have been produced in the galaxies hosted within the nebula, and re-scattered by neutral hydrogen.

Social security reform in Central and Eastern Europe: variations on a Latin American theme.

Science.gov (United States)

Kritzer, B E

After Chile reformed its social security system in 1981, several other Latin American countries and certain Central and Eastern European (CEE) countries implemented the Chilean model, with some variations: either a single- or multitier system, or with a period of transition to take care of those in the labor force at the time of the change. The single-tier version consists of individual accounts in pension fund management companies. Multi-tier systems retain some form of public program and add mandatory individual accounts. Most of the CEE countries did not want to incur the high transition costs associated with the Chilean model. The switch to a market economy had already strained their economies. Also, the countries' desire to adopt the European Union's Euro as their currency--a move that required a specific debt ceiling--limited the amount of additional debt they could incur. This article describes the CEE reforms and makes some comparisons with the Latin American experience. Most of the CEE countries have chosen a mixed system and have restructured the pay-as-you-go (PAYGO) tier, while the Latin American countries have both single- and multi-tier systems. Some CEE countries have set up notional defined contribution (NDC) schemes for the PAYGO tier in which each insured person has a hypothetical account made up of all contributions during his or her working life. Survivors and disability programs in CEE have remained in the public tier, but in most of the Latin American programs the insured must purchase a separate insurance policy. Issues common to both regions include: Administrative costs are high and competition is keen, which has led to consolidation and mergers among the companies and a large market share controlled by a few companies. Benefits are proportionately lower for women than for men. A large, informal sector is not covered by social security. This sector is apparently much larger in Latin America than in the CEE countries. Issues that are unique

Castaneda, D M; Collins, B E

1998-09-01

Perceptions of persons who introduce condoms in an ongoing sexual interaction, and the effects of gender and ethnicity on these perceptions, were explored in a study involving 243 students at a large, urban university in the western US. 133 of these students identified themselves as Mexican American; the remaining students indicated they were White. A vignette methodology was used to elicit perceptions of condom introducers on six scales (Nice, Exciting, Sexually Attractive, Promiscuous, Good Relationship Partner, Unpersonable/Personable). Data were analyzed in a 2 (gender of participant) x 2 (gender of condom introducer) x 3 (low acculturated Mexican American, high acculturated Mexican American, White) x 2 (presence/absence of close relationship theme) analysis of variance and covariance. In terms of the Nice Scale, women rated condom introducers significantly higher than men, female condom introducers were rated significantly higher than male introducers, and condom introducers who expressed a care and responsibility theme while introducing a condom were rated significantly higher than those who expressed no theme. On the Exciting Scale, women condom introducers were rated significantly higher than men. Condom introducers who expressed a care and responsibility theme were rated significantly higher than those who expressed no theme on the Good Relationship Partner scale. Men rated the female condom introducer significantly higher than women on the Promiscuous scale. Low acculturated Mexicans rated the female condom introducer significantly higher than the male introducer on the Promiscuous scale and rated the condom introducer significantly higher than Whites on the Sexually Attractive scale. These findings attest that many often contradictory interpersonal gender- and ethnicity-related perceptions operate in sexual encounters.

Nanomedicine plays a prominent role among emerging technologies. The spectrum of potential applications is as broad as it is promising. It includes the use of nanoparticles and nanodevices for diagnostics, targeted drug delivery in the human body, the production of new therapeutic materials as well as nanorobots or nanoprotheses. Funding agencies are investing large sums in the development of this area, among them the European Commission, which has launched a large network for life-sciences related nanotechnology. At the same time government agencies as well as the private sector are putting forward reports of working groups that have looked into the promises and risks of these developments. This paper will begin with an introduction to the central ethical themes as identified by selected reports from Europe and beyond. In a next step, it will analyse the most frequently invoked ethical concerns-risk assessment and management, the issues of human identity and enhancement, possible implications for civil liberties (e.g. nanodevices that might be used for covert surveillance), and concerns about equity and fair access. Although it seems that the main ethical issues are not unique to nanotechnologies, the conclusion will argue against shrugging them off as non-specific items that have been considered before in the context of other biomedical technologies, such as gene therapy or xenotransplantation. Rather, the paper will call on ethicists to help foster a rational, fair and participatory discourse on the different potential applications of nanotechnologies in medicine, which can form the basis for informed and responsible societal and political decisions.

The PISA results for Indonesian Students are lowest among Asian countries in the past two successive results. Therefore various Innovations in science learning process and its effectiveness enhancing student's science literacy is needed to enrich middle school science teachers. Literacy strategies have been implemented on health technologies theme learning to enhance Indonesian Junior high school Student's Physics literacy in three different health technologies e.g. Lasik surgery that associated with application of Light and Optics concepts, Ultra Sonographer (USG) associated with application of Sound wave concepts and Work out with stationary bike and walking associated with application of motion concepts. Science learning process involves at least teacher instruction, student learning and a science curriculum. We design two main part of literacy strategies in each theme based learning. First part is Integrated Reading Writing Task (IRWT) is given to the students before learning process, the second part is scientific investigation learning process design packed in Problem Based Learning. The first part is to enhance student's science knowledge and reading comprehension and the second part is to enhance student's science competencies. We design a transformation from complexity of physics language to Middle school physics language and from an expensive and complex science investigation to a local material and simply hands on activities. In this paper, we provide briefly how literacy strategies proposed by previous works is redesigned and applied in classroom science learning. Data were analysed using t- test. The increasing value of mean scores in each learning design (with a significance level of p = 0.01) shows that the implementation of this literacy strategy revealed a significant increase in students’ physics literacy achievement. Addition analysis of Avarage normalized gain show that each learning design is in medium-g courses effectiveness category

2018-01-01

Female genital cutting (FGC) has major implications for women's physical, sexual and psychological health, and eliminating the practice is a key target for public health policy-makers. To date one of the main barriers to achieving this has been an inability to infer privately-held views on FGC within communities where it is prevalent. As a sensitive (and often illegal) topic, people are anticipated to hide their true support for the practice when questioned directly. Here we use an indirect questioning method (unmatched count technique) to identify hidden support for FGC in a rural South Central Ethiopian community where the practice is common, but thought to be in decline. Employing a socio-demographic household survey of 1620 Arsi Oromo adults, which incorporated both direct and indirect direct response (unmatched count) techniques we compare directly-stated versus privately-held views in support of FGC, and individual variation in responses by age, gender and education and target female (daughters versus daughters-in-law). Both genders express low support for FGC when questioned directly, while indirect methods reveal substantially higher acceptance (of cutting both daughters and daughters-in-law). Educated adults (those who have attended school) are privately more supportive of the practice than they are prepared to admit openly to an interviewer, indicating that education may heighten secrecy rather than decrease support for FGC. Older individuals hold the strongest views in favour of FGC (particularly educated older males), but they are also more inclined to conceal their support for FGC when questioned directly. As these elders represent the most influential members of society, their hidden support for FGC may constitute a pivotal barrier to eliminating the practice in this community. Our results demonstrate the great potential for indirect questioning methods to advance knowledge and inform policy on culturally-sensitive topics like FGC; providing more

"The Voyage of the Dawn Treader": The World at the Dawn of 2006-2011. Understanding societal themes

Full Text Available This article offers a snapshot of the societal dynamics of individual countries around the world, integrated into a global view to provide the tourism and hospitality industry insight into potential customer needs and perceptions. The OPUS Reports on the Global Dynamics at the Dawn of 20...are published annually since 2006 in the Journal of Organisational and Social Dynamics in London. The researchers were interested in a metaphoric tour of the world's social dynamics over time as perceived from both the Systems psychodynamics and Positive psychology theoretical paradigms. The research methodology was qualitative using a case study approach where each of the six (2006- 2011 years' integrated hypotheses was studied as a separate case study. The six cases were integrated into new hypotheses reflecting how global social dynamics changed over the years. The findings were presented as hypotheses per individual country followed by an integrated global hypothesis. The three main emerging themes were framed as Identity, Hope and Love. Identity contains the sub-theme of Facelessness, described as the fragmentation of cultures, a loss of cultural identity and a search for shared social meaning. Hope embodies the theme Knight/s in shining armour which describes youth as saviours and Obama as saviour. The loss of Hope is illustrated by the sub-themes of the impotence of the older generation, pessimism, fear and the death of a way of life. Love consists of human connection described as affiliation, support and trust. The lack of Love consists of human alienation described as loneliness, aggression and violence. The findings of the study identify societal themes that can be operationalized in the tourism and hospitality industry through targeted offerings to provide in the unmet needs of society. In addition, training interventions to improve customer service and return on investment can be based on the findings of this research.

2015-05-01

Photo-elicitation interviews (PEIs) were conducted to explore the role of place in recovery - specifically, narrative identity reconstruction - among persons with complex needs. PEIs with 17 formerly homeless adults with co-occurring disorders in New York City produced 243 photos. Content analysis of photos revealed three categories - apartment, neighborhood and people. Two narrative themes - having my own and civic identity - were mapped onto the apartment and neighborhood categories, respectively. Three additional cross-categorical narrative themes were identified: (re)negotiating relationships and boundaries, moving beyond old identities and future possibilities. Housing was central across themes. Understanding of recovery is enhanced when viewed through participant-controlled visual methods. Copyright © 2015 Elsevier Ltd. All rights reserved.

Gómez Paz María

2011-01-01

Full Text Available The authors examined themes in written narratives of second grade students including gender and ethnic differences. Eighty-seven stories were considered for this research, six general themes were found, and content and comparative analyses were performed among themes. Children tended to write more frequently about personal experiences and activities, and about settings that involved nature and animals; however, interactivity and social context was almost always present in children’s stories. Boys and girls tended to write about almost the same topics, with a higher tendency of girls to write about family including female characters performing gender-oriented tasks. Finally, the researchers found some ethnic differences in children’s stories, especially fantasy stories, nature, and family.

Mitochondrial DNA Variation Reveals a Sharp Genetic Break within the Distribution of the Blue Land Crab Cardisoma guanhumi in the Western Central Atlantic

Full Text Available The blue land crab Cardisoma guanhumi is widely distributed throughout tropical and subtropical estuarine regions in the Western Central Atlantic (WCA. Patterns of population genetic structure and historical demographics of the species were assessed by mtDNA control region sequence analysis to examine the connectivity among five populations (n = 97 within the region for future conservation strategies and decision-making of fishery management. A total of 234 polymorphic nucleotides were revealed within the sequence region, which have defined 93 distinct haplotypes. No dominant mtDNA haplotypes were found but instead a distribution of a few low-frequency recurrent haplotypes with a large number of singletons. A NJ-tree and a median-joining haplotype network revealed two distinct clusters, corresponding to individuals from estuaries located along the Caribbean Sea and Brazilian waters, respectively. AMOVA and FST statistics supported the hypothesis that two main geographic regions exists. Phylogeographical discontinuity was further demonstrated by the Bayesian assignment analysis and a significant pattern of isolation-by-distance. Additionally, tests of neutral evolution and analysis of mismatch distribution indicate a complex demographic history in the WCA, which corresponds to bottleneck and subsequent population growth. Overall, a sharp genetic break between Caribbean and Brazilian populations raised concerns over the conservation status of the blue land crab.

This report covers the topics of discussion and the recommendations of the panel members. On December 8 and 9, 2010, the Geochemistry, Biogeochemistry, and Subsurface Science (GBSS) Science Theme Advisory Panel (STAP) convened for a more in-depth exploration of the five Science Theme focus areas developed at a similar meeting held in 2009. The goal for the fiscal year (FY) 2011 meeting was to identify potential topical areas for science campaigns, necessary experimental development needs, and scientific members for potential research teams. After a review of the current science in each of the five focus areas, the 2010 STAP discussions successfully led to the identification of one well focused campaign idea in pore-scale modeling and five longer-term potential research campaign ideas that would likely require additional workshops to identify specific research thrusts. These five campaign areas can be grouped into two categories: (1) the application of advanced high-resolution, high mass accuracy experimental techniques to elucidate the interplay between geochemistry and microbial communities in terrestrial ecosystems and (2) coupled computation/experimental investigations of the electron transfer reactions either between mineral surfaces and outer membranes of microbial cells or between the outer and inner membranes of microbial cells.

Revealing Physical Activity of GRB Central Engine with Macronova/Kilonova Data

The modeling of Li-Paczyński macronova/kilonova signals gives a reasonable estimate on the neutron-rich material ejected during the neutron star mergers. Usually the accretion disk is more massive than the macronova ejecta, with which the efficiencies of converting the disk mass into prompt emission of three merger-driven GRBs can hence be directly constrained. Supposing the macronovae/kilonovae associated with GRB 050709, GRB 060614, and GRB 130603B arose from radioactive decay of the r -process material, the upper limit on energy conversion efficiencies are found to be as low as ∼10{sup −6}–10{sup −4}. Moreover, for all three events, neutrino annihilation is likely powerful enough to account for the brief gamma-ray flashes. Neutrino annihilation can also explain the “extended” emission lasting ∼100 s in GRB 050709, but does not work for the one in GRB 060614. These progresses demonstrate that the macronova can serve as a novel probe of the central engine activity.

Picturing Christ’s childhood: Some examples of a rare iconographic theme inspired by the infancy gospels

Directory of Open Access Journals (Sweden)

Fundić Leonela

2013-01-01

Full Text Available This article examines Byzantine wall paintings dated to the thirteenth and fourteenth century depicting a rare iconographic theme of Jesus’s childhood inspired by the Infancy Gospels. The iconography shows the Virgin Mary leading the child Jesus by the hand. The child is depicted holding different objects, such as a writing tablet, an unfurled scroll, or a wicker basket filled with flowers or fruits. Several of the scenes under examination have been hitherto misidentified or altogether unknown. In addition to this, the article interprets these representations in a broader iconographic context and addresses the possible origin of the theme.

The central image of a gravitationally lensed quasar.

Science.gov (United States)

Winn, Joshua N; Rusin, David; Kochanek, Christopher S

2004-02-12

A galaxy can act as a gravitational lens, producing multiple images of a background object. Theory predicts that there should be an odd number of images produced by the lens, but hitherto almost all lensed objects have two or four images. The missing 'central' images, which should be faint and appear near the centre of the lensing galaxy, have long been sought as probes of galactic cores too distant to resolve with ordinary observations. There are five candidates for central images, but in one case the third image is not necessarily the central one, and in the others the putative central images might be foreground sources. Here we report a secure identification of a central image, based on radio observations of one of the candidates. Lens models using the central image reveal that the massive black hole at the centre of the lensing galaxy has a mass of 20,000M(o) pc(-2), which is in agreement with expections based on observations of galaxies that are much closer to the Earth.

The Use of the Technique of «Theme Photobooks» in the Work with Children with Autism Spectrum Disorders or Intellectual Disorders

Full Text Available The technique of «Theme Photobooks» is chosen out of the method of phototherapy and is developed by a group of American specialists in the process of remedial work with children or adults with disturbance of devel¬opment or autistic spectrum disorders. «Theme Photobooks» are an optional tool for remedial activities with children, enabling their development. Activities with Theme Photobooks consist of several stages: choice of an interesting or relevant for the child topic, selection of the objects for photographing, creation of photobooks (selection of images, their placement, making up the inscription to the photo, creation of the stories based on the pictures. The use of the technique of «Theme Photobooks» increases the intensity of communication pro¬cesses, which leads to the normalization of the child’s behaviour and considerably extends the chances of social integration.

Colonialism’s Past and Present: Performing History at a Gold Rush Theme Park

Full Text Available The urge to seize, to claim the past in order to experience the truth of history is a powerful impulse - one full of desire for a time apart from the here and now. Conceiving and sustaining an experience of the past is today very big business. The ongoing development of the heritage, tourism and re-enactment industries inter-link with popular historical perception in ways that raise multiple questions about the relationship between popular and academic accounts of the past and the many other ways of performing history (Dening 1996. This paper takes as its starting point a gold rush theme park, Old Mogo Town in NSW Australia, and in particular, its erasure of all evidence of the Indigenous past. From here, it is my aim to develop a revised performance of that past- one that interrogates the catastrophe of colonialism and the fate of history currently expunged from the gold rush theme park of Old Mogo Town.

Trends in the investigation of social determinants of health: selected themes and methods

Directory of Open Access Journals (Sweden)

Roger Keller Celeste

2011-01-01

Full Text Available We analyze bibliometric trends of topics relevant to the epidemiologic research of social determinants of health. A search of the PubMed database, covering the period 1985-2007, was performed for the topics: socioeconomic factors, sex, race/ethnicity, discrimination/prejudice, social capital/support, lifecourse, income inequality, stress, behavioral research, contextual effects, residential segregation, multilevel modeling, regression based indices to measure inequalities, and structural equation modeling/causal diagrams/path analysis. The absolute, but not the relative, frequency of publications increased for all themes. Total publications in PubMed increased 2.3 times, while the subsets of epidemiology/public health and social epidemiologic themes/methods increased by factors of 5.3 and 5.2, respectively. Only multilevel and contextual analyses had a growth over and above that observed for epidemiology/public health. We conclude that there is clearly room for wider use of established techniques, and for new methods to emerge when they satisfy theoretical needs.

Clark, Geoffrey R.; Reepmeyer, Christian; Melekiola, Nivaleti; Woodhead, Jon; Dickinson, William R.; Martinsson-Wallin, Helene

2014-07-01

Tonga was unique in the prehistoric Pacific for developing a maritime state that integrated the archipelago under a centralized authority and for undertaking long-distance economic and political exchanges in the second millennium A.D. To establish the extent of Tonga's maritime polity, we geochemically analyzed stone tools excavated from the central places of the ruling paramounts, particularly lithic artifacts associated with stone-faced chiefly tombs. The lithic networks of the Tongan state focused on Samoa and Fiji, with one adze sourced to the Society Islands 2,500 km from Tongatapu. To test the hypothesis that nonlocal lithics were especially valued by Tongan elites and were an important source of political capital, we analyzed prestate lithics from Tongatapu and stone artifacts from Samoa. In the Tongan state, 66% of worked stone tools were long-distance imports, indicating that interarchipelago connections intensified with the development of the Tongan polity after A.D. 1200. In contrast, stone tools found in Samoa were from local sources, including tools associated with a monumental structure contemporary with the Tongan state. Network analysis of lithics entering the Tongan state and of the distribution of Samoan adzes in the Pacific identified a centralized polity and the products of specialized lithic workshops, respectively. These results indicate that a significant consequence of social complexity was the establishment of new types of specialized sites in distant geographic areas. Specialized sites were loci of long-distance interaction and formed important centers for the transmission of information, people, and materials in prehistoric Oceania.

In this paper, we describe how the hypergeometric test can be used to determine whether a given theme of interest occurs in a storyset at a frequency more than would be expected by chance. By a storyset we mean simply a list of stories defined according to a common attribute (e.g. author, movement, period). The test works roughly as follows: Given a background storyset (e.g. 19th century adventure novels), and a sub-storyset of interest (e.g. Jules Verne novels), the test determines whether a...

Societal acceptance of wind farms: Analysis of four common themes across Australian case studies

International Nuclear Information System (INIS)

Hall, N.; Ashworth, P.; Devine-Wright, P.

2013-01-01

Australia's renewable energy target (RET) seeks to provide 20 per cent of Australia's electricity generation from renewable energy sources by 2020. As wind power is relatively advanced, it was anticipated that wind power will contribute a major component of the early target. However, high levels of societal resistance to wind farms, combined with new regulatory policies, indicate the RET may not be dominated by wind power. This research involved an examination of seven case studies around wind farm deployment. Qualitative interviews were the primary data for the case studies and analysed using methods informed by grounded theory. Despite the diversity of stakeholder views, the qualitative analysis identified strong community support for wind farms but four common themes emerged that influence this societal acceptance of wind farms in Australia: trust, distributional justice, procedural justice and place attachment. Without addressing these factors through integration into policy development and engagement approaches, wind energy is unlikely to provide the early and majority of new renewable energy. Similar international experiences are incorporated in the discussion of the Australian wind industry's societal acceptance. - Highlights: ► Seven case studies of wind farms in Australia are described. ► Acceptance affects whether wind significantly contributes to the Aust. RE target. ► Four themes were identified regarding societal acceptance of Australian wind farms. ► Four themes are trust, distributional and procedural justice, and place attachment. ► International similarities to the Australian experience are provided

It is sustained on competency-based education and constructionism, due to they appeal to humanism to deal current problems. It is composed of four phases: committee conformation, theoretical and conceptual concerning analysis, construction and application of instruments on a PE, and identification of the cross-curricular theme level. Even though the proposed methodology is applied to the environment, it is feasible to adapt to other axes, such as human rights, multiculturalism, and poverty, relevant to the educational context of the state of Guerrero.

Central sensitization: implications for the diagnosis and treatment of pain.

Science.gov (United States)

Woolf, Clifford J

2011-03-01

Nociceptor inputs can trigger a prolonged but reversible increase in the excitability and synaptic efficacy of neurons in central nociceptive pathways, the phenomenon of central sensitization. Central sensitization manifests as pain hypersensitivity, particularly dynamic tactile allodynia, secondary punctate or pressure hyperalgesia, aftersensations, and enhanced temporal summation. It can be readily and rapidly elicited in human volunteers by diverse experimental noxious conditioning stimuli to skin, muscles or viscera, and in addition to producing pain hypersensitivity, results in secondary changes in brain activity that can be detected by electrophysiological or imaging techniques. Studies in clinical cohorts reveal changes in pain sensitivity that have been interpreted as revealing an important contribution of central sensitization to the pain phenotype in patients with fibromyalgia, osteoarthritis, musculoskeletal disorders with generalized pain hypersensitivity, headache, temporomandibular joint disorders, dental pain, neuropathic pain, visceral pain hypersensitivity disorders and post-surgical pain. The comorbidity of those pain hypersensitivity syndromes that present in the absence of inflammation or a neural lesion, their similar pattern of clinical presentation and response to centrally acting analgesics, may reflect a commonality of central sensitization to their pathophysiology. An important question that still needs to be determined is whether there are individuals with a higher inherited propensity for developing central sensitization than others, and if so, whether this conveys an increased risk in both developing conditions with pain hypersensitivity, and their chronification. Diagnostic criteria to establish the presence of central sensitization in patients will greatly assist the phenotyping of patients for choosing treatments that produce analgesia by normalizing hyperexcitable central neural activity. We have certainly come a long way since the

Full Text Available Violence is an inseparable part of our lives. Mass media is the public domain in which the violence is widely presented. Among all the mass media mediums which have numerous functions in our daily lives such as informing, entertaining, educating, etc.; television, without a doubt, takes the highest amount of time. In recent years, the number of television series on channels has increased and the fact of violence has been presented in these programs. Here in this research it has been questioned whether physical, psychological and verbal violence are used in love-themed TV series or not; and if yes, it has been questioned who is inflicting violence towards whom. In this context four love-themed TV series which were broadcasted in four Turkish channels with the highest rating record between the years of 2006 and 2010 were studied by using content analysis method in accordance with the violence categories. The data gathered by the analysis has shown that not only the series based on action; but also the series based on human affairs such as family, friendship, love, etc. include violence.

Neural computational modeling reveals a major role of corticospinal gating of central oscillations in the generation of essential tremor

Directory of Open Access Journals (Sweden)

Hong-en Qu

2017-01-01

Full Text Available Essential tremor, also referred to as familial tremor, is an autosomal dominant genetic disease and the most common movement disorder. It typically involves a postural and motor tremor of the hands, head or other part of the body. Essential tremor is driven by a central oscillation signal in the brain. However, the corticospinal mechanisms involved in the generation of essential tremor are unclear. Therefore, in this study, we used a neural computational model that includes both monosynaptic and multisynaptic corticospinal pathways interacting with a propriospinal neuronal network. A virtual arm model is driven by the central oscillation signal to simulate tremor activity behavior. Cortical descending commands are classified as alpha or gamma through monosynaptic or multisynaptic corticospinal pathways, which converge respectively on alpha or gamma motoneurons in the spinal cord. Several scenarios are evaluated based on the central oscillation signal passing down to the spinal motoneurons via each descending pathway. The simulated behaviors are compared with clinical essential tremor characteristics to identify the corticospinal pathways responsible for transmitting the central oscillation signal. A propriospinal neuron with strong cortical inhibition performs a gating function in the generation of essential tremor. Our results indicate that the propriospinal neuronal network is essential for relaying the central oscillation signal and the production of essential tremor.

2011-03-01

This paper reports the management of two clinical cases, in which the upper right central incisor was fused with a supernumerary tooth and the upper left central incisor was macrodontic. A radiographic examination revealed that the fused teeth had two separate roots. Hemisectioning of the fused teeth was performed, the supernumerary portion was extracted and the remaining part was reshaped to remove any sharp margins and to achieve a normal morphology. The macrodontic central incisors were not treated. At 12-months post-surgery there were no periodontal problems and no hypersensitivity. Orthodontic treatment was performed to appropriately align the maxillary teeth and to correct the malocclusion.

Four themes that underlie the high-level nuclear waste management program

International Nuclear Information System (INIS)

Sprecher, W.M.

1989-01-01

In 1982, after years of deliberation and in response to mounting pressures from environmental, industrial, and other groups, the US Congress enacted the Nuclear Waste Policy Act (NWPA) of 1982, which was signed into law by the President in January 1983. That legislation signified a major milestone in the nation's management of high-level nuclear waste, since it represented a consensus among the nation's lawmakers to tackle a problem that had evaded solution for decades. Implementation of the NWPA has proven to be exceedingly difficult, as attested by the discord generated by the US Department of Energy's (DOE's) geologic repository and monitored retrievable storage (MRS) facility siting activities. The vision that motivated the crafters of the 1982 act became blurred as opposition to the law increased. After many hearings that underscored the public's concern with the waste management program, the Congress enacted the Nuclear Waste Policy Amendments Act of 1987 (Amendments Act), which steamlined and focused the program, while establishing three independent bodies: the MRS Review Commission, the Nuclear Waste Technical Review Board, and the Office of the Nuclear Waste Negotiator. Yet, even as the program evolves, several themes characterizing the nation's effort to solve the waste management problem continue to prevail. The first of these themes has to do with social consciousness, and the others that follow deal with technical leadership, public involvement and risk perceptions, and program conservatism

We present Very Large Telescope/Spectrograph for INtegral Field Observations in the Near Infrared H - and K -band spectra of potential central stars within the inner 8″-by-8″ regions of 55 MIPSGAL “bubbles” (MBs), sub-arcminute circumstellar shells discovered in the mid-IR survey of the Galactic plane with Spitzer /MIPS. At magnitudes brighter than 15, we detect a total of 230 stars in the K band and 179 stars in the H band. We spectrally identify 145 stars in all but three MBs, with average magnitudes of 13.8 and 12.7 respectively, using spectral libraries and previous studies of near-IR stellar spectra. We also use tabulated intrinsic stellar magnitudes and colors to derive distances and extinction values, and to better constrain the classifications of the stars. We reliably identify the central sources for 21 of the 55 MBs, which we classify as follows: one Wolf–Rayet, three luminous blue variable candidates, four early-type (O to F), and 15 late-type (G to M) stars. The 21 central sources are, on average, one magnitude fainter than these in the most recent study of MBs, and we notice a significant drop in the fraction of massive star candidates. For the 34 remaining MBs in our sample, we are unable to identify the central sources due to confusion, low spectroscopic signal-to-noise ratio, and/or lack of detections in the images near the centers of the bubbles. We discuss how our findings compare with previous studies and support the trend, for the most part, between the shells’ morphologies in the mid-IR and central sources spectral types.

Mitochondrial DNA reveals regional and interregional importance of the central Mediterranean African shelf for loggerhead sea turtles (Caretta caretta

Directory of Open Access Journals (Sweden)

Paolo Casale

2008-09-01

Full Text Available The wide north African continental shelf in the central Mediterranean is known to be one of the few important areas in the basin for loggerhead turtles in the neritic stage. In order to assess the origin of these turtles, sequences of the mtDNA control region were obtained from 70 turtles caught by bottom trawlers in the area, and compared with known sequences from turtles from Mediterranean and Atlantic nesting sites. Five haplotypes were identified (Haplotype diversity = 0.262; nucleotide diversity = 5.4×10-3. Specific haplotypes indicate contributions from distant rookeries such as Turkey and the Atlantic, which shows that Atlantic turtles entering the Mediterranean while in the oceanic phase use at least one Mediterranean continental shelf as a neritic foraging ground. A new haplotype and another one previously found only in foraging areas, highlight the genetic information gaps for nesting sites, which undermine powerful mixed stock analyses. Despite these limitations, the results reveal the regional importance of the study area as a neritic foraging ground for turtles that are probably from most of the Mediterranean nesting aggregates. Therefore, reducing turtle mortality resulting from the high fishing effort in the area should be regarded as key for Mediterranean turtle conservation and is also possibly important for Atlantic populations.

The World Health Organization Comprehensive Mental Health Action Plan (CMHAP) 2013-2020 proposes the implementation of primary prevention strategies to reduce the mental health burden of disease. The extent to which Israeli academic programs and published research adhere to the principles spelled out by the CMHAP is unknown. To investigate the presence of mental health primary prevention themes in published research and academic programs in Israel. We searched for mental health primary prevention themes in: (1) three major journals of psychiatry and social sciences during the years 2001-2012; (2) university graduate programs in psychology, social work and medicine in leading universities for the academic year of 2011-2012; and (3) doctoral and master's theses approved in psychology and social work departments in five universities between the years 2007-2012. We used a liberal definition of primary prevention to guide the above identification of themes, including those related to theory, methods or research information of direct or indirect application in practice. Of the 934 articles published in the three journals, 7.2%, n = 67, addressed primary prevention. Of the 899 courses in the 19 graduate programs 5.2%, n = 47, elective courses addressed primary prevention. Of the 1960 approved doctoral and master's theses 6.2%, n = 123, addressed primary prevention. Only 11 (4.7%) articles, 5 (0.6%) courses, and 5 (0.3%) doctoral and master's theses addressed primary prevention directly. The psychiatric reform currently implemented in Israel and WHO CMHAP call for novel policies and course of action in all levels of prevention, including primary prevention. Yet, the latter is rarely a component of mental health education and research activities. The baseline we drew could serve to evaluate future progress in the field.

Ritchey crater is a ∼79 km diameter complex crater near the boundary between Hesperian ridged plains and Noachian highland terrain on Mars (28.8°S, 309.0°E) that formed after the Noachian. High Resolution Imaging Science Experiment (HiRISE) images of the central peak reveal fractured massive bedrock and megabreccia with large clasts. Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) spectral analysis reveals low calcium pyroxene (LCP), olivine (OL), hydrated silicates (phyllosilicates) and a possible identification of plagioclase bedrock. We mapped the Ritchey crater central uplift into ten units, with 4 main groups from oldest and originally deepest to youngest: (1) megabreccia with large clasts rich in LCP and OL, and with alteration to phyllosilicates; (2) massive bedrock with bright and dark regions rich in LCP or OL, respectively; (3) LCP and OL-rich impactites draped over the central uplift; and (4) aeolian deposits. We interpret the primitive martian crust as igneous rocks rich in LCP, OL, and probably plagioclase, as previously observed in eastern Valles Marineris. We do not observe high-calcium pyroxene (HCP) rich bedrock as seen in Argyre or western Valles Marineris. The association of phyllosilicates with deep megabreccia could be from impact-induced alteration, either as a result of the Richey impact, or alteration of pre-existing impactites from Argyre basin and other large impacts that preceded the Ritchey impact, or both.

In this study, we examined the direct effect of (positive vs. negative) evaluation of potentially harassing experiences due to ethnic background on impaired well-being as well as the moderating effect of ethnic identity centrality on the relationship between (lower vs. higher) frequency of potentially harassing experiences and impaired well-being. Using a gender-balanced sample with equal proportions of black and minority ethnic and white undergraduate students (N = 240), we found that, expectedly, ethnic identity centrality intensified the effects of higher frequency of potentially harassing experiences on lower self-esteem and lower positive affect. Unexpectedly, however, gender identity centrality buffered the effects of higher frequency as well as more negative evaluation of potentially harassing experiences on lower self-esteem, indicating that gender identity centrality may be a protective resource, even though it is not specific to ethnic harassment. Exploratory analyses revealed that for black and minority ethnic respondents with high ethnic identity centrality and for white respondents with low ethnic identity centrality, there were associations between more negative evaluation of potentially harassing experiences and lower self-esteem and lower positive affect. This finding might indicate that ethnic identity centrality was a risk factor in black and ethnic minority respondents, but a protective factor in white respondents.

Subsurface geologic features of the 2011 central Virginia earthquakes revealed by airborne geophysics

2014-01-01

Characterizing geologic features associated with major earthquakes provides insights into mechanisms contributing to fault slip and assists evaluation of seismic hazard. We use high-resolution airborne geophysical data combined with ground sample measurements to image subsurface geologic features associated with the 2011 moment magnitude (Mw) 5.8 central Virginia (USA) intraplate earthquake and its aftershocks. Geologic mapping and magnetic data analyses suggest that the earthquake occurred near a complex juncture of geologic contacts. These contacts also intersect a >60-km-long linear gravity gradient. Distal aftershocks occurred in tight, ~1-km-wide clusters near other obliquely oriented contacts that intersect gravity gradients, in contrast to more linearly distributed seismicity observed at other seismic zones. These data and corresponding models suggest that local density contrasts (manifested as gravity gradients) modified the nearby stress regime in a manner favoring failure. However, along those gradients seismic activity is localized near structural complexities, suggesting a significant contribution from variations in associated rock characteristics such as rheological weakness and/or rock permeability, which may be enhanced in those areas. Regional magnetic data show a broader bend in geologic structures within the Central Virginia seismic zone, suggesting that seismic activity may also be enhanced in other nearby areas with locally increased rheological weaknesses and/or rock permeability. In contrast, away from the Mw5.8 epicenter, geophysical lineaments are nearly continuous for tens of kilometers, especially toward the northeast. Continuity of associated geologic structures probably contributed to efficient propagation of seismic energy in that direction, consistent with moderate to high levels of damage from Louisa County to Washington, D.C., and neighboring communities.

Full Text Available Krzysztof Penderecki (born 1933 is considered to be one of the most outstanding contemporary composers. The religious theme is often taken to be an inspiration for his vocal-instrumental output. Penderecki presents in his compositions the religious and moral problems related to the human nature and existence. The principal issues in his activity are a trial to find a reason of evil and misfortune and also the vision of ordeal. The composer makes use of not only biblical and liturgical texts but also religious poetry mainly in latin language. His religious output has a concert character thanks to the musician language and composing techniques. His own commentaries concerning his compositions prove that his religious activity is an artistic confession of his faith.

Genome-wide transcriptional profiling reveals two distinct outcomes in central Nervous system infections of rabies virus

Directory of Open Access Journals (Sweden)

Daiting eZhang

2016-05-01

Full Text Available Rabies remains a major public health concern in many developing countries. The precise neuropathogenesis of rabies is unknown, though it is hypothesized to be due to neuronal death or dysfunction. Mice that received intranasal inoculation of an attenuated rabies virus (RABV strain HEP-Flury exhibited subtle clinical signs, and eventually recovered, which is different from the fatal encephalitis caused by the virulent RABV strain CVS-11. To understand the neuropathogenesis of rabies and the mechanisms of viral clearance, we applied RNA sequencing (RNA-Seq to compare the brain transcriptomes of normal mice versus HEP-Flury or CVS-11 intranasally inoculated mice. Our results revealed that both RABV strains altered positively and negatively the expression levels of many host genes, including genes associated with innate and adaptive immunity, inflammation and cell death. It is found that HEP-Flury infection can activate the innate immunity earlier through the RIG-I/MDA-5 signaling, and the innate immunity pre-activated by HEP-Flury or Newcastle disease virus (NDV infection can effectively prevent the CVS-11 to invade central nervous system (CNS, but fails to clear the CVS-11 after its entry into the CNS. In addition, following CVS-11 infection, genes implicated in cell adhesion, blood vessel morphogenesis and coagulation were mainly up-regulated, while the genes involved in synaptic transmission and ion transport were significantly down-regulated. On the other hand, several genes involved in the MHC class II-mediated antigen presentation pathway were activated to a greater extent after the HEP-Flury infection as compared with the CVS-11 infection suggesting that the collaboration of CD4+ T cells and MHC class II-mediated antigen presentation is critical for the clearance of attenuated RABV from the CNS. The differentially regulated genes reported here are likely to include potential therapeutic targets for expanding the postexposure treatment window

. "Let me tell you about my little box": phenomenological study on the experience of living with a totally implantable central venous catheter. Many variables impact on the choice to implant a totally implantable long-term central venous catheter's (Port), in spite of its proven efficacy. The patients' perception is pivotal, and only few qualitative studies dig deep into patients' feelings and experiences. To understand if, and how, the Port affects the patient's life. Qualitative phenomenological study based on semi-structured interviews on a convenience sample of patients implanted a Port, selected in an oncohematology Day Hospital in Milan. The analysis was carried out by three researchers with a phenomenological method. Four main themes, and sub-themes, emerged from twenty interviews. Relief, both physical and psychological; the process of the choice of inserting the Port and the importance of thinking about its positioning since the beginning of the treatment course; the symbol- the device reminds of the disease and its removal is of utmost importance; the technology progresses- the need of trust in the health care personnel and in their competences. The Port improved the patients' quality of life. The study allows some reflections on the need of considering the actual and future conditions of the patient to make a shared and informed choice.

Full Text Available Since the mid-20th century, the Pyrenean pastoral social-ecological system (SES has undergone socioeconomic and demographic transformations leading to changes in grazing practices and a decline in the livestock industry. Land abandonment has contributed to an ecological transition from herbaceous vegetation cover to shrublands and forests, leading to a loss of ecosystem services, including biodiversity and forage. I interviewed 27 stockmen (ganaderos in two valleys of the central Pyrenees to document their traditional ecological knowledge and observations of environmental, social, economic, and cultural changes in the valleys. I used poetic analysis, a qualitative data analysis approach, to illustrate and analyze one ganadero's experience of social-ecological change. First, I created seven poems based on an interview transcript with this ganadero. Second, I analyzed the poetry I created, to see what new insights and understanding about system dynamics and the lived experience of SES change emerged from analysis of the transcript re-presented as poetry. Third, I compared key themes that emerged from this analysis with findings across the other 26 interviews. Fourth, I read the poems and presented the associated analysis to multiple audiences, to gauge their impact and effectiveness in communicating research findings. Finally, I synthesized across the themes raised in the seven poems. Poetic analysis revealed emotional and cultural dimensions of change, especially the importance of occupational and place identity, in the experience of the ganadero. The transcript re-presented as poetry portrayed the ganadero as an agent in creating and maintaining a cultural landscape and as both an adaptor and resister to SES change. Poetic analysis also uncovered telling contradictions, adaptive capacities, and barriers to adaptation in this SES that went unappreciated with conventional qualitative analysis approaches. This exploratory study illustrates the

Patients who undergo knee replacement surgery may need to receive a blood transfusion due to blood loss during the operation. Therefore it was important to improve the design of knee implant operative procedures in an attempt to reduce the rate of blood loss. The present study aimed to compare the blood loss between two types of knee replacement surgery. This is a retrospective study in which 78 patients received cemented knee replacements in Phayao Hospital between October 2010 and March 2012. There were two types of surgical procedure: 1) using an implant position covering the end of the femoral bone without cutting into the central part of the distal femoral, 2) using an implant position covering the end of the femoral bone cutting the central part of the distal femoral. Blood loss, blood transfusion, hemoglobin and hematocrit were recorded preoperatively, immediately postsurgery and 48 hours after surgery. Findings revealed that the knee replacement surgery using the implant position covering the end of the femoral bone without cutting the central part of the distal femoral significantly lowered the rate of blood loss when compared to using the implant position covering the end of the femoral bone with central cutting of the distal femor. The average blood loss during the operation without cutting at the central part of distal femoral was 49.50 ± 11.11 mL; whereas the operation cutting the central part of the distal femoral was 58.50 ± 11.69 mL. As regards blood loss, the knee replacement surgery using the implant position covering the end ofthefemoral bone without cutting the central part of distal femor was better than using the implant position covering the end of the femoral bone cutting at the central part of the distal femor.

Hemi-central retinal artery occlusion in young adults

Directory of Open Access Journals (Sweden)

Rishi Pukhraj

2010-01-01

Full Text Available Amongst the clinical presentations of retinal artery occlusion, hemi-central retinal artery occlusion (Hemi-CRAO is rarely described. This case series of four adults aged between 22 and 36 years attempts to describe the clinical profile, etiology and management of Hemi-CRAO. Case 1 had an artificial mitral valve implant. Polycythemia and malignant hypertension were noted in Case 2. The third patient had Leiden mutation while the fourth patient had Eisenmenger′s syndrome. Clinical examination and fundus fluorescein angiography revealed a bifurcated central retinal artery at emergence from the optic nerve head, in all cases. Color Doppler examination of the central retinal artery confirmed branching of the artery behind the lamina cribrosa. It is hypothesized that bifurcation of central retinal artery behind the lamina cribrosa may predispose these hemi-trunks to develop an acute occlusion if associated with underlying risk factors. The prognosis depends upon arterial recanalisation and etiology of the thromboembolic event.

To study multifocal electroretinogram (mfERG) and its relation to retinal sensitivity assessed by Humphrey visual field (HVF) analysis in central areolar choroidal dystrophy (CACD). Seven eyes of 4 patients with CACD and 15 normal control subjects were examined. mfERG and central 30/2 HVF were tested for each participant. Ring analysis in mfERG was evaluated. HVF results were evaluated in 5 concentric rings in order to compare the results to concentric ring analysis in mfERG. The differences between control subjects and patients were evaluated by Mann-Whitney U test and the correlations were assessed by Spearman test. Mean Snellen acuity was 0.49+/-0.10 in patients. HVF revealed central scotoma in 6 of 7 eyes (85.7%), whereas a paracentral scotoma extending to fixation point was detected in 1 eye. The retinal sensitivities in 5 concentric rings in HVF were significantly lower (p<0.001 for ring 1 to ring 4, and p=0.017 in ring 5) in CACD patients. Similarly, CACD patients had lower P1/N1 amplitudes (p<0.05) and delayed P1/N1 implicit times (p<0.05). In CACD, in the areas of scotoma detected by HVF, mfERG values were depressed. However, both mfERG and HVF abnormalities were found outside the areas of ophthalmoscopically normal retinal areas.

Modelling the migration and accumulation of radionuclides in forest ecosystems. Report of the Forest Working Group of BIOMASS Theme 3

International Nuclear Information System (INIS)

2002-08-01

The IAEA Programme on BIOsphere Modelling and ASSessment (BIOMASS) was launched in Vienna in October 1996. The programme was concerned with developing and improving capabilities to predict the transfer of radionuclides in the environment. The programme had three themes: Theme 1: Radioactive Waste Disposal. The objective was to develop the concept of a standard or reference biosphere for application to the assessment of the long-term safety of repositories for radioactive waste. Under the general heading of 'Reference Biospheres', six Task Groups were established: Task Group 1: Principles for the Definition of Critical and Other Exposure Groups. Task Group 2: Principles for the Application of Data to Assessment Models. Task Group 3: Consideration of Alternative Assessment Contexts. Task Group 4: Biosphere System Identification and Justification. Task Group 5: Biosphere System Descriptions. Task Group 6: Model Development. Theme 2: Environmental Releases. BIOMASS provided an international forum for activities aimed at increasing the confidence in methods and models for the assessment of radiation exposure related to environmental releases. Two Working Groups addressed issues concerned with the reconstruction of radiation doses received by people from past releases of radionuclides to the environment and the evaluation of the efficacy of remedial measures. Theme 3: Biosphere Processes. The aim of this Theme was to improve capabilities for modelling the transfer of radionuclides in particular parts of the biosphere identified as being of potential radiological significance and where there were gaps in modelling approaches. This topic was explored using a range of methods including reviews of the literature, model inter-comparison exercises and, where possible, model testing against independent sources of data. Three Working Groups were established to examine the modelling of: (1) long-term tritium dispersion in the environment; (2) radionuclide uptake by fruits; and (3

‘Violence against the Earth is Violence against Women’: The Rape Theme in Women’s Eco-Narratives

Directory of Open Access Journals (Sweden)

Deborah Saidero

2017-11-01

Full Text Available The metaphorical connection between women and the Earth is a recurring literary trope which is often articulated through the theme of rape. In many narratives the sexual abuse of women is, for instance, equated with the colonial penetration and conquering of the land. Today many women writers have undertaken a plight to subvert destructive colonialist and capitalistic attitudes that have normalized violence against women’s bodies and against the Earth. This essay analyses the theme of rape in the works of three Canadian novelists (Maracle, Brand and Atwood whose eco-narratives summon environmental justice by retrieving an ethos of respect for the woman-land connection.

2004-01-01

Direct-to-consumer (DTC) advertising of prescription drugs is a widely discussed issue in health care. However, little is known about the characteristics of the motivational themes used in this type of advertising. The aim of this study was to investigate the concurrent presentation of motivational themes in DTC print and television advertisements. The content analyses focused on advertisements of 2 targeted drug classes (cyclooxygenase-2 enzyme inhibitors and 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors) in magazines and on television. Targeted print advertisements (for celecoxib, rofecoxib, atorvastatin, pravastatin, and simvastatin) from September to December 2001 and targeted television advertisements (for celecoxib, rofecoxib, and simvastatin) from November 2001 were investigated. The motivational themes were assessed using a theoretical framework based on self-regulatory focus theory and cultural orientation. Self-regulatory focus was examined in terms of goal orientation (promotion vs prevention) and emotional aspects, (e.g., cheerfulness, dejection, quiescence, agitation). The cultural orientation was examined in terms of individualism versus collectivism. The visual-verbal match was categorized as direct if the audio and visual information was semantically redundant, as partial if it was partially related, and as no match at all if it was different or conflicting. Twelve print advertisements in 10 magazines and 4 television advertisements on 4 television networks were examined; the interrater reliability scores from 3 independent, trained judges ranged from 0.93 to 0.99. The score was low (0.57) in the visual-verbal match measurement for television advertisements. Products in the same category appeared to be promoted using different self-regulatory foci. For example, celecoxib and atorvastatin advertisements tended to be promotion oriented, whereas pravastatin advertisements tended to be prevention oriented. Motivational themes were found

Rotgans, Jerome I

2012-10-01

The present study aimed at providing an overview of the most common themes of research into medical education. Changes in frequency of occurrence of these themes over time and differences between US and European journals were studied. The most productive institutions and researchers in the field were examined. A content analysis was carried out on 10,168 abstracts extracted from the six most influential journals in medical education published since 1988. Twenty-nine major themes were identified, of which student assessment, clinical and communication skills, clinical clerkships, and problem-based learning were the most prominent ones. Some of these themes, such as multiple-choice examinations or computer-assisted instruction seemed to have had their day, whereas other topics, such as the study of clinical clerkships, clinical reasoning, and scholarship in education were on their way up. Medical education research turned out to be a thoroughly international affair to which both US and European research centers contribute. The medical education literature shows an overwhelming emphasis on the preparation of medical students for professional practice. Moreover, the emphasis is very much on the individual student; most research seems to have been conducted with a psychological perspective in mind. It is argued that medical education research would profit from broadening its scope, including sociological, economical, ecological, and system perspectives. These perspectives might bring answers to new questions relevant to the quality of medical education. It is suggested that medical education is in need of moving beyond the conventional effectiveness-driven research approach to a more theory- and discovery-driven approach.

Serosurvey Reveals Exposure to West Nile Virus in Asymptomatic Horse Populations in Central Spain Prior to Recent Disease Foci.

Abad-Cobo, A; Llorente, F; Barbero, M Del Carmen; Cruz-López, F; Forés, P; Jiménez-Clavero, M Á

2017-10-01

West Nile fever/encephalitis (WNF) is an infectious disease affecting horses, birds and humans, with a cycle involving birds as natural reservoirs and mosquitoes as transmission vectors. It is a notifiable disease, re-emerging in Europe. In Spain, it first appeared in horses in the south (Andalusia) in 2010, where outbreaks occur every year since. However, in 2014, an outbreak was declared in horses in central Spain, approximately 200 km away from the closest foci in Andalusia. Before that, evidence of West Nile virus (WNV) circulation in central Spain had been obtained only from wildlife, but never in horses. The purpose of this work was to perform a serosurvey to retrospectively detect West Nile virus infections in asymptomatic horses in central Spain from 2011 to 2013, that is before the occurrence of the first outbreaks in the area. For that, serum samples from 369 horses, collected between September 2011 and November 2013 in central Spain, were analysed by ELISA (blocking and IgM) and confirmed by virus neutralization, proving its specificity using parallel titration with another flavivirus (Usutu virus). As a result, 10 of 369 horse serum samples analysed gave positive results by competitive ELISA, 5 of which were confirmed as positive to WNV by virus neutralization (seropositivity rate: 1.35%). One of these WNV seropositive samples was IgM-positive. Chronologically, the first positive samples, including the IgM-positive, corresponded to sera collected in 2012 in Madrid province. From these results, we concluded that WNV circulated in asymptomatic equine populations of central Spain at least since 2012, before the first disease outbreak reported in this area. © 2016 Blackwell Verlag GmbH.

The familial clustering observed in chronic kidney disease of uncertain etiology (CKDu) characterized by tubulointerstitial damages in the North Central Region of Sri Lanka strongly suggests the involvement of genetic factors in its pathogenesis. The objective of the present study is to use whole-exome sequencing to identify the genetic variants associated with CKDu. Whole-exome sequencing of eight CKDu cases and eight controls was performed, followed by direct sequencing of candidate loci in 301 CKDu cases and 276 controls. Association study revealed rs34970857 (c.658G > A/p.V220M) located in the KCNA10 gene encoding a voltage-gated K channel as the most promising SNP with the highest odds ratio of 1.74. Four rare variants were identified in gene encoding Laminin beta2 (LAMB2) which is known to cause congenital nephrotic syndrome. Three out of four variants in LAMB2 were novel variants found exclusively in cases. Genetic investigations provide strong evidence on the presence of genetic susceptibility for CKDu. Possibility of presence of several rare variants associated with CKDu in this population is also suggested.

Realistic teenage fiction with a sexrelated theme: Readers’ responses to Slinger-slinger by Francois Bloemhof

Full Text Available Francois Bloemhof submitted his novel for teenagers, “Slinger-slinger” for the Sanlam competition for youth fiction in 1996. Eventually this prizewinner in the beginners’ category was published in 1997. The main theme of “Slinger-slinger” is the sexual awakening and identity of teenagers. A study was undertaken to obtain the opinions of teenage readers about the success of “Slinger-slinger” as a whole, as well as to gauge the success of integrating sexual aspects in this novel. The study also served to obtain information about the reading needs of teenage readers with regard to realistic teenage fiction and teenage fiction with a sex-related theme. The findings of the study underlying this article indicated that the participating teenage readers regarded “Slinger-slinger” as successful and interesting, and that they would like to read more realistic Afrikaans teenage fiction such as “Slinger-slinger”.

Variations in dream recall frequency and dream theme diversity by age and sex

Full Text Available We assessed dream recall frequency and dream theme diversity with an internet questionnaire among a cohort of 28,888 male and female participants aged 10 to 79 years in a cross-sectional design. Dream recall frequency increased from adolescence (ages 10-19 to early adulthood (20-29 and then decreased again for the next 20 years. The nature of this decrease differed for males and females. For males, it began earlier (30-39, proceeded more gradually, and reached a nadir earlier (40-49 than it did for females. For females, it began later (40-49, dropped more abruptly, and reached nadir later (50-59. Marked sex differences were observed for age strata 10-19 through 40-49 and year-by-year analyses estimated the window for these differences to be more precisely from 14-44 yrs. Dream theme diversity decreased linearly with age for both sexes up to 50-59 and then dropped even more sharply for 60-79. There was a sex difference favouring males on this measure but only for ages 10-19. Findings replicate, in a single sample, those from several previous studies showing an increase in dream recall frequency from adolescence to early adulthood, a subsequent decrease in dream recall frequency—primarily in early and middle adulthood, and different patterns of age-related decrease in the two sexes. Age-related changes in sleep structure, such as decreasing %REM sleep, parallel the observed dream recall changes but are much smaller and more gradual in nature. Changes in the phase and amplitude of circadian rhythms of REM propensity and generational differences in life experiences may also account for some part of the findings. However, that decreases in dream theme diversity parallel known age-related decreases in episodic and autobiographical memory may signify that the diversity measure indexes an aspect of autobiographical memory that is specific to dream recall.

Central Hemodynamics and Microcirculation in Critical Conditions

Full Text Available Objective: to compare central hemodynamic and microcirculatory changes in critical conditions caused by different factors and to reveal their possible differences for a further differentiated approach to intensive therapy. Subjects and methods. The study covered 16 subjects with severe concomitant injury (mean age 41.96±2.83 years and 19 patients with general purulent peritonitis (mean age 45.34±2.16 years. Their follow-up was 7 days. The central hemodynamics was estimated by transpulmonary thermodilution using a Pulsion PiCCO Plus system (Pulsion Medical Systems, Germany. The microcirculatory bed was evaluated by cutaneous laser Doppler flowmetry using a LAKK-02 capillary blood flow laser analyzer (LAZMA Research-and-Production Association, Russian Federation. Results. The pattern of central hemodynamic and microcirculatory disorders varies with the trigger that has led to a critical condition. Central hemodynamics should be stabilized to ensure the average level of tissue perfusion in victims with severe concomitant injury. In general purulent peritonitis, microcirculatory disorders may persist even if the macrohemodynamic parameters are normal. Conclusion. The macrohemodynamic and microcirculatory differences obtained during the study suggest that a complex of intensive therapy should be differentiated and, if the latter is used, it is necessary not only to be based on the central hemodynamics, but also to take into consideration functional changes in microcirculation. Key words: severe concomitant injury, general purulent peritonitis, micro-circulation, central hemodynamics, type of circulation.

Demographic model of the Neolithic transition in Central Europe

Directory of Open Access Journals (Sweden)

Patrik Galeta

2009-12-01

Full Text Available Several recent lines of evidence indicate more intensive contact between LBK farmers and indigenous foragers in Central Europe (5600–5400 calBC. Strong continuity has been identified between Mesolithic and Neolithic material cultures; faunal assemblages, and isotopic analyses of diet have revealed a greater role of hunting in LBK communities; genetic analyses have suggested that the modern Central European gene pool is mainly of Palaeolithic origin. Surprisingly little attention has been paid to demographic aspects of the Neolithic transition. In our study, demographic simulations were performed to assess the demographic conditions that would allow LBK farmers to spread across central Europe without any admixture with Mesolithic foragers. We constructed a stochastic demographic model of changes in farming population size. Model parameters were constrained by data from human demography, archaeology, and human ecology. Our results indicate that the establishment of farming communities in Central Europe without an admixture with foragers was highly improbable. The demographic conditions necessary for colonization were beyond the potential of the Neolithic population. Our study supports the integrationists’ view of the Neolithic transition in Central Europe.

Identity as Fleeting Fashion? Revealing the Background of Popularity Through Bosniaherzegovina’s Adoption of Bruce Lee

Directory of Open Access Journals (Sweden)

Alenka Bartulović

2007-12-01

Full Text Available This paper reflects on the background to popular research on identification processes in modern ethnology and cultural or social anthropology. By discussing themes closely connected to identity (national and popular culture, and the construction of Others, the author reveals that identity is not merely a redundant trend that researchers recklessly pursue, but that it reflects the need to reveal existing uncertainties and is an attempt to revise errors made to date, as well as lapses of the discipline we work in. The author primarily focuses on national identity and its situational transformations and intertwining with other existing identities. Bosnia-Herzegovina is placed at the center of interest. This theoretically oriented text concludes by analyzing the idea of erecting a monument to Bruce Lee in Mostar, which reveals the full complexity of identity processes around a world marked by intense and unique global and transnational currents.

Full Text Available Current research investigates the ideas and practices of a team of teachers of the Natural Sciences working in schools in the state of Paraná, Brazil, with regard to pedagogical workshops as teaching and learning strategies on Hydrographic Basin as theme. A continuous formation course was conducted on the theme, with data retrieved by a questionnaire applied prior to the course and after the development of workshops by the teachers. Films, recordings and descriptive memorials were analyzed according to content analysis. Results showed that teachers endeavored to problematize in the pedagogical workshops, coupled to teachers´ mediation to go beyond common sense. Students´ participation was the great progress mediated by workshops. On the other hand, interdisciplinarity and the problematization of teaching were the limiting presuppositions for their execution. The undertaking enhanced a better understanding of pedagogical workshops in the teaching of the sciences, with the need for greater investments in teachers´ continuous formation to enhance the development of teaching practices that attend to current demands in science teaching.

Allen, H M

1994-10-01

This project developed and tested a population-based survey, the HS Form, to examine health and health care in the Central Iowa community. Data from this new collection of proven sets of items were used to compare competing health plans, doctor offices, hospitals, and to develop preliminary norms of the community's insured, in two areas: system performance and health burden. The results showed that the survey: (1) was both feasible and efficient in delivering a comprehensive and generic assessment of consumers and patients; (2) revealed consistent, noteworthy differences between plans and between providers across both sets of criteria; and (3) indicated that there is substantial room for improvement in Central Iowa's health care delivery system from the public's perspective. Recommendations for next steps include: (1) following through on the June 1993 community forum (held to discuss the project's methods and results with local decision makers); (2) broadening the evaluation design to increase sample representativeness; and (3) implementing a pre/post approach to measure changes in plan and provider performance.

Unusual anatomy of maxillary central incisor with two roots

Directory of Open Access Journals (Sweden)

T S Ashwini Shivakumar

2012-01-01

Full Text Available Introduction: Knowledge of root canal morphology is essential for successful endodontic therapy. Failure to recognize unusual root canal anatomy may lead to unsuccessful endodontic treatment. Case Report: This case report describes the successful endodontic treatment of the maxillary central incisor with unusual anatomy of two roots and two root canals. A 23-year-old male patient was referred for dental consultation with discoloration of the maxillary right central incisor with periapical lesion, which revealed unusual anatomy of root on radiographic examination, and was confirmed upon exploration. Discussion: As described by Vertucci, the maxillary central incisor presents a single root and single root canal in 100% of the cases. However, few cases of maxillary central incisors with two canals were reported in the literature, most of which were associated with developmental anomalies like fusion, germination or dens invaginatus. Clinician should be aware of the unusual anatomical variations that should be detected by the different diagnostic resources available.

Bell, R; Meiselman, H L; Pierson, B J; Reeve, W G

1994-02-01

We investigated whether a change in the perceived ethnicity of a food can be produced without manipulating the food item itself, and if that change in ethnic perception is accompanied by a change in acceptability and food selection behavior. Italian and British foods were offered in a British restaurant for four days. Foods were offered for 2 days under control conditions, when the restaurant was decorated as usual. The identical foods then were offered in the restaurant for 2 more days under experimental conditions, when ethnic names were used on the menu to describe foods, and the restaurant was decorated with an Italian theme. Perceived ethnicity and acceptability of items were rated by customers each day, and item selection was tracked. The Italian theme increased selection of pasta and dessert items, and decreased the selection of fish. The Italian theme also increased the perceived Italian ethnicity of British pasta items, fish and veal, and increased the perceived Italian ethnicity of the meal overall. These findings show that changes in perceived ethnicity and food selection can be accomplished without altering food items, but merely by manipulating the environment, and may imply a unique strategy for increasing perceived menu variety.

Obsolete tobacco control themes can be hazardous to public health: the need for updating views on absolute product risks and harm reduction

Directory of Open Access Journals (Sweden)

Lynn T. Kozlowski

2016-05-01

Full Text Available Abstract Background Leading themes have guided tobacco control efforts, and these themes have changed over the decades. When questions arose about health risks of tobacco, they focused on two key themes: 1 how bad is the problem (i.e., absolute risk and 2 what can be done to reduce the risk without cessation (i.e., prospects for harm reduction. Using the United States since 1964 as an example, we outline the leading themes that have arisen in response to these two questions. Initially, there was the recognition that “cigarettes are hazardous to health” and an acceptance of safer alternative tobacco products (cigars, pipes, light/lower-tar cigarettes. In the 1980s there was the creation of the seminal theme that “Cigarettes are lethal when used as intended and kill more people than heroin, cocaine, alcohol, AIDS, fires, homicide, suicide, and automobile crashes combined.” By around 2000, support for a less-dangerous light/lower tar cigarette was gone, and harm reduction claims were avoided for products like cigars and even for smokeless tobacco which were summarized as “unsafe” or “not a safe alternative to cigarettes.” Discussion The Surgeon General in 2014 concluded that by far the greatest danger to public health was from cigarettes and other combusted products. At the same time the evidence base for smokeless tobacco and alternative nicotine delivery systems (ANDS had grown. Product innovation and tobacco/nicotine bio-behavioral, epidemiological and public health sciences demonstrate that low nitrosamine smokeless tobacco (e.g., Swedish snus, and ANDS have substantially lower harms than cigarettes. Going forward, it is important to sharpen themes and key messages of tobacco control, while continuing to emphasize the extreme lethality of the inhaled smoke from cigarettes or from use of any combusting tobacco product. Summary Implications of updating the leading themes for regulation, policymaking and advocacy in tobacco control

Imperatives in informal organizational resource exchange in Central Europe

Directory of Open Access Journals (Sweden)

David Jancsics

2015-01-01

Full Text Available This paper challenges the mainstream social scientific approach that emphasizes “moral inferiority” in corruption and bribery in Central and Eastern Europe. We argue that in many cases, people participate in informal organizational resource exchanges not because of immorality or greed but rather because of powerful external forces. By using the case of contemporary Hungary to support this argument, this paper provides a systematic analysis of such imperatives. The findings of 50 in-depth qualitative interviews suggest that two main imperatives can be distinguished; macro-level social and meso-level organizational forces. Macro-level forces may be linked to historical paths, Hungary's socialist and pre-socialist social conditions, and its post-socialist welfare state development. Meso-level organizational forces are more general phenomena and can be found in many other countries in the world. Moreover, there are numerous categories within each theme. Some of them represent normative imperatives, while others are more material structural forces.

Neuroleadership: Themes and limitations of an emerging interdisciplinary field.

Science.gov (United States)

Kuhlmann, Naila; Kadgien, Chelsie A

2018-05-01

The relationship between brain and behaviour has perplexed philosophers and scientists since the time of the ancient Greeks. Recent technological advances have allowed neuroscience to flourish, alongside growing romanticism that reductionist studies will allow us to understand complex interpersonal behaviours. Organizational cognitive neuroscience and neuroleadership are newly established interdisciplinary fields that use neuroscientific techniques to answer questions about behaviours within organizations. Neuroleadership aims to discover screening tools for good leaders, to improve leadership skills, and to identify unconscious factors affecting behaviour in hopes of improving management and leadership practices. Although proponents of neuroleadership are optimistic, if we know anything about the functions of the human brain and our interpersonal behaviours, it is that they are exquisitely complex and context dependant. Here, we briefly discuss the major themes emerging in the new field of neuroleadership and the limitations and potential consequences of applying findings from the field prematurely and with blind optimism.

2016-01-01

Purpose To identify perceptions of how sociocultural environment enabled and hindered physical activity (PA) participation. Design Community-based participatory research. Setting Two semirural and two urban communities located in Alberta, Canada. Participants Thirty-five people (74.3% females, 71.4% aged 25–64 years) across the four communities. Method PhotoVoice activities occurred over 3 months during the spring of 2009. Participants were asked to document perceived environmental attributes that might foster or inhibit PA in their community. Photographs and narratives were shared in one-on-one interviews. Line-by-line coding of the transcripts was independently conducted by two researchers using an inductive approach. Codes were arranged into themes and subthemes, which were then organized into the Analysis Grid for Environments Linked to Obesity (ANGELO) framework. Results Six main themes (accompanied by subthemes) emerged: sociocultural aesthetics, safety, social involvement, PA motivation, cultural ideas of recreation, and car culture. Representative quotes and photographs illustrate enablers and obstacles identified by participants. Conclusion This PhotoVoice study revealed how aspects of participants’ sociocultural environments shaped their decisions to be physically active. Providing more PA resources is only one step in the promotion of supportive environments. Strategies should also account for the beautification and maintenance of communities, increasing feelings of safety, enhancement of social support among community members, popularization of PA, and mitigating car culture, among others.

Calcitonin and calcitonin receptor-like receptors: common themes with family B GPCRs?

Science.gov (United States)

Barwell, James; Gingell, Joseph J; Watkins, Harriet A; Archbold, Julia K; Poyner, David R; Hay, Debbie L

2012-05-01

The calcitonin receptor (CTR) and calcitonin receptor-like receptor (CLR) are two of the 15 human family B (or Secretin-like) GPCRs. CTR and CLR are of considerable biological interest as their pharmacology is moulded by interactions with receptor activity-modifying proteins. They also have therapeutic relevance for many conditions, such as osteoporosis, diabetes, obesity, lymphatic insufficiency, migraine and cardiovascular disease. In light of recent advances in understanding ligand docking and receptor activation in both the family as a whole and in CLR and CTR specifically, this review reflects how applicable general family B GPCR themes are to these two idiosyncratic receptors. We review the main functional domains of the receptors; the N-terminal extracellular domain, the juxtamembrane domain and ligand interface, the transmembrane domain and the intracellular C-terminal domain. Structural and functional findings from the CLR and CTR along with other family B GPCRs are critically appraised to gain insight into how these domains may function. The ability for CTR and CLR to interact with receptor activity-modifying proteins adds another level of sophistication to these receptor systems but means careful consideration is needed when trying to apply generic GPCR principles. This review encapsulates current thinking in the realm of family B GPCR research by highlighting both conflicting and recurring themes and how such findings relate to two unusual but important receptors, CTR and CLR. © 2011 The Authors.

"Old Oxen Cannot Plow": Stereotype Themes of Older Adults in Turkish Folklore.

Science.gov (United States)

Marcus, Justin; Sabuncu, Neslihan

2016-12-01

Although much research has established the nature of attitudes and stereotypes toward older adults, there are conflicting explanations for the root cause of ageism, including the sociocultural view and interpersonal views, that age bias against older adults is uniquely a product of modernity and occurs through social interactions, and the evolutionary view and intraindividual views, that age bias against older adults is rooted in our naturally occurring and individually held fear of death. We make initial investigations into resolving this conflict, by analyzing literature from a society predating the Industrial Revolution, the society of Ottoman Turks. Using Grounded Theory, we analyzed 1,555 Turkish fairy tales of the most well-known older adult in Turkish folklore, Nasreddin Hoca, for stereotype themes of older adults. Using the same method, we then analyzed 22,000+ Turkish sayings and proverbs for the same themes. Results indicated older adults to be viewed both positively and negatively. Positive stereotypes included wisdom, warmth, deserving of respect, and retirement. Negative stereotypes included incompetence, inadaptability, and frailty/nearing of death. Older females were viewed more negatively relative to older males. Results indicated views of older adults to parallel those found in contemporary research. Results have implications for the design of interventions to reduce ageism and on the cross-cultural generalizability of age-based stereotypes. © The Author 2015.

Recent studies have supported the safety and efficacy of psychedelic therapy for mood disorders and addiction. Music is considered an important component in the treatment model, but little empirical research has been done to examine the magnitude and nature of its therapeutic role. The present study assessed the influence of music on the acute experience and clinical outcomes of psychedelic therapy. Semi-structured interviews inquired about the different ways in which music influenced the experience of 19 patients undergoing psychedelic therapy with psilocybin for treatment-resistant depression. Interpretative phenomenological analysis was applied to the interview data to identify salient themes. In addition, ratings were given for each patient for the extent to which they expressed "liking," "resonance" (the music being experienced as "harmonious" with the emotional state of the listener), and "openness" (acceptance of the music-evoked experience). Analyses of the interviews revealed that the music had both "welcome" and "unwelcome" influences on patients' subjective experiences. Welcome influences included the evocation of personally meaningful and therapeutically useful emotion and mental imagery, a sense of guidance, openness, and the promotion of calm and a sense of safety. Conversely, unwelcome influences included the evocation of unpleasant emotion and imagery, a sense of being misguided and resistance. Correlation analyses showed that patients' experience of the music was associated with the occurrence of "mystical experiences" and "insightfulness." Crucially, the nature of the music experience was significantly predictive of reductions in depression 1 week after psilocybin, whereas general drug intensity was not. This study indicates that music plays a central therapeutic function in psychedelic therapy.

The Dubbing of Gay-themed TV Series in Italy: Corpus-based Evidence of Manipulation and Censorship

Directory of Open Access Journals (Sweden)

Annalisa Sandrelli

2016-02-01

Full Text Available The manipulation and censorship of taboo and sensitive references in AVT has attracted the interest of several scholars over the last few years, but systematic studies of the impact of such practices on different genres in different countries are still needed. The paper analyses the Italian dubbing of three gay-themed TV series, Queer as Folk, Queer as Folk (US remake, and The L Word. Gay-themed series are less mainstream on Italian TV channels than in the UK and the USA, and gayspeak as a linguistic phenomenon is not well-known to Italian audiences. Consequently, the Italian dubbed dialogues are the product of different degrees of manipulation and even censorship. The paper finds empirical evidence of such alterations in data from the DubTalk corpus and attempts a tentative evaluation of the impact of such practices on the Italian versions of the above-mentioned series.

Centralization and decentralization in energy systems and associated risks

Full text of publication follows: the concept of centralization/decentralization is - considering its widespread use - surprisingly ill-defined. Within the SERF-program (Socio Economic Research on Fusion) an attempt is made to clarify the complex issue of centralization/decentralization and to analyze its expected interaction with electricity production system in the case of nuclear fusion. Fusion research at the time is a multinational, highly centralized undertaking. As a result of this, and due to the expected large energy production units, it is generally expected that fusion will be embedded in a highly centralized, international energy supply system. The degree of centralization of an energy supply system, however, is believed to have for reaching consequences on the stability of the system, and beyond that, on decision making processes in energy policy, as well as democratic structures on the national or even international level. Internationalization might require control instruments that do not exist so far. Amongst other reservations, it is the possibly unwanted consequences of such a highly centralized, international energy supply system that limit acceptance of the fusion technology in the public. Therefore, centralization and decentralization trends of energy supply systems over the years are being looked at, to study their influence on the political and social systems (and vice-versa). In a first step, an attempt is made to classify centralization. Careful analyses and evaluation of available literature revealed a broad spectrum of different forms and degrees of centralization. Various parameters describing energy production and distribution are used. A differentiation of centralization on a technical and on an organizational level seems necessary, although they are not fully independent of each other. Beyond this, the choice of parameters must depend on the questions to be addressed. A new approach defining different levels and degrees of

The paper put forward the hypothesis that changes in the list of journals, particularly in the number of periodicals published in specific Central and Eastern European (CEE) countries, have a significant impact on bibliometric indicators and, consequently, on the convergence levels they are used to measure. The analyses presented in the article support the argument that countries from Central and Eastern Europe, despite showing fairly consistent convergence trends, achieve noticeably weaker results than Western Europe regarding research and development and scientific activity. The evident impact made by the inclusion of numerous CEE journals in WoS on the values of the indicator analysed, directly supports the hypothesis put forward in this article. The results of the study are important because data on the number of publications and citations in the Web of Science are increasingly used as development indicators of national R&D sectors. By showing how modifications in these databases influence the results obtained, we can better understand and thus make better use of data from these sources. The article concludes with listing the possibilities for furthering and deepening selected themes pointed out in the paper. (Author)

"Anonymous Meltdown": Content Themes Emerging in a Nonfacilitated, Peer-only, Unstructured, Asynchronous Online Support Group for Family Caregivers.

Diefenbeck, Cynthia A; Klemm, Paula R; Hayes, Evelyn R

2017-12-01

By providing care for loved ones in the home, family caregivers save millions of dollars for our overtaxed healthcare system. Support groups can lighten the psychological burden of caregiving. Nonprofessionally facilitated (or peer) online caregiver support groups can help meet a critical need in healthcare as a low-cost resource for caregivers. Online caregiver peer support groups can promote the health and well-being of family caregivers and, by extension, the patients themselves, resulting in cost-savings for society. A better understanding of these types of groups is of critical importance, given the unrelenting pace of demographic shift in the United States. The purpose of this study was to examine content themes emerging from an unstructured, asynchronous online peer support group for family caregivers of people with chronic illness. Qualitative content analysis was used, yielding six themes: "experiencing the emotional toll," "need for catharsis/venting," "finding the silver linings," "seeking specific advice/problem solving," "realizing home is no longer a haven," and "adapting to the caregiver role." The themes reflect what emerged organically in an online support group that was not professionally facilitated or structured in any way. Heterogeneity in the relationship between caregivers and care recipients may negatively affect outcomes and requires further study.

The changing climate and human vulnerability in north-central Namibia

2016-01-01

Full Text Available North-central Namibia is more vulnerable to effects of climate change and variability. Combined effects of environmental degradation, social vulnerability to poverty and a changing climate will compromise subsistence farming in north-central Namibia (NCN. This will make subsistence and small-scale farmers in the region more vulnerable to projected changes in the climate system. Thus, the aim of this article was to examine factors contributing to subsistence farmers’ vulnerability to impacts of climate change. The article further discusses different aspects of human vulnerability and existing adaptation strategies in response to impacts of climate related disasters experienced over the past three to four decades in NCN. Qualitative and quantitative research approaches and methodology were employed to obtain information from subsistence farmers in north-central Namibia. The sociodemographic characteristics of Ohangwena, Oshana and Omusati Region reveals high levels of unemployment, high adult and elderly population and high dependency on agricultural livelihood system. These indicators help understand levels of household vulnerability. The study concludes that households interviewed revealed low levels of adaptive capacity due to exposure to climate risks and combined effects of social, political and cultural factors. This article provided an understanding that is required to inform the adaptation pathways relevant for NCN.

Full Text Available The Crucifixion of Christ is one of the major Biblical events in the context of the four Gospels, also marking one of the most frequently met themes in the iconography of Christian art. The focus of the paper is to underline the main aspects of the visual representation of this tense moment in the history of Christianity, referring to representative works of the artistic heritage inspired by the event of Christ’s death on the cross. Thus, a number of famous works of art history are analyzed in relation to the described composition, the represented characters and their importance. They belong both to traditional artistic fields, such as painting, to modern ones, thus taking into account some of the most popular film representations on this topic.

Recreating Jane: “Austenland” and the Regency Theme Park

Directory of Open Access Journals (Sweden)

Maddalena Pennacchia

2017-12-01

Full Text Available In the maze of Austen’s ever-expanding textuality – with its prequels, sequels, rewritings and adaptations – it may be worth paying attention to an unpretentious little book by Shannon Hale titled Austenland (2007. The story is about the adventures of a New Yorker thirty-something with a name that says it all: Jane. Being obsessed with Mr Darcy as played by Colin Firth, she decides to be healed by her excessive Austenian fantasies (or rather to indulge in them for the last time by spending all her savings on a English Regency Theme park that promises to offer Janeites a real full immersive Austen experience. What interests me in this post-Austenian story is the embedded discourse of leisure and tourism in the age of participatory culture, when an everywoman like Jane brings to the fore the need to be more involved in re-creative activities that are triggered by reading Austen’s novels.

Measuring the operational efficiency of individual theme park attractions.

Kim, Changhee; Kim, Soowook

2016-01-01

This study assesses the operation efficiency of theme park attractions using the data envelopment analysis, utilizing actual data on 15 attractions at Samsung Everland located in Yongin-si, Republic of Korea. In particular, this study identifies crowding and waiting time as one of the main causes of visitor's satisfaction, and analyzes the efficiency of individual attractions in terms of waiting time. The installation area, installation cost, and annual repair cost are set as input factors and the number of annual users and customer satisfaction as output factors. The results show that the roller coaster-type attractions were less efficient than other types of attractions while rotating-type attractions were relatively more efficient. However, an importance performance analysis on individual attraction's efficiency and satisfaction showed that operational efficiency should not be the sole consideration in attraction installation. In addition, the projection points for input factors for efficient use of attractions and the appropriate reference set for benchmarking are provided as guideline for attraction efficiency management.

Fractal systems of central places based on intermittency of space-filling

International Nuclear Information System (INIS)

Chen Yanguang

2011-01-01

Highlights: → The idea of intermittency is introduced into central place model. → The revised central place model suggests incomplete space filling. → New central place fractals are presented for urban analysis. → The average nearest distance is proposed to estimate the fractal dimension. → The concept of distance-based space is replaced by that of dimension-based space. - Abstract: The central place models are fundamentally important in theoretical geography and city planning theory. The texture and structure of central place networks have been demonstrated to be self-similar in both theoretical and empirical studies. However, the underlying rationale of central place fractals in the real world has not yet been revealed so far. This paper is devoted to illustrating the mechanisms by which the fractal patterns can be generated from central place systems. The structural dimension of the traditional central place models is d = 2 indicating no intermittency in the spatial distribution of human settlements. This dimension value is inconsistent with empirical observations. Substituting the complete space filling with the incomplete space filling, we can obtain central place models with fractional dimension D < d = 2 indicative of spatial intermittency. Thus the conventional central place models are converted into fractal central place models. If we further integrate the chance factors into the improved central place fractals, the theory will be able to explain the real patterns of urban places very well. As empirical analyses, the US cities and towns are employed to verify the fractal-based models of central places.

Full Text Available Purpose. Subthreshold diode micropulse laser (SDM treatment is believed to be safe method of treating clinical entities involving retinal edema. We present a case of serous edematous reaction of the retina to SDM treatment. Methods. Case report. Results. A patient with chronic central serous chorioretinopathy (CSCR was treated with SDM Yellow multispot laser. Procedure had been preceded by careful titration of the laser power, which after achieving of the threshold parameter was decreased by 50%. The follow-up visit two days after treatment revealed significant central retinal edema and subretinal fluid. Fundus autofluorescence image showed thermal reaction from the RPE in the form of small spots of hyperfluorescence corresponding to the laser multispot pattern used for treatment. Retinal edema resolved after topical bromfenac and single intravitreal bevacizumab injection. Slight pigmentary reaction from the RPE persisted. Conclusion. In the treatment of CSCR, there is a need to significantly reduce threshold SDM power parameters or simply use very low power without titration.

According to the study, we reveal that medicinal plant commodities in Central Java province have average score 8.52, indicating a strong comparative advantage in global markets, while the commodities appear to have average score of 0.97 at 0 to 1 range, representing a strong competitiveness. Those results are attributed to natural and environmental condition, as well as high demand of global market. This competitiveness will encourage traditional/modern medicinal industries in global market.

The five senses have specific ways to receive environmental information and lead to central nervous system. The perception of time is the sum of stimuli associated with cognitive processes and environmental changes. Thus, the perception of time requires a complex neural mechanism and may be changed by emotional state, level of attention, memory and diseases. Despite this knowledge, the neural mechanisms of time perception are not yet fully understood. The objective is to relate the mechanisms involved the neurofunctional aspects, theories, executive functions and pathologies that contribute the understanding of temporal perception. Articles form 1980 to 2015 were searched by using the key themes: neuroanatomy, neurophysiology, theories, time cells, memory, schizophrenia, depression, attention-deficit hyperactivity disorder and Parkinson's disease combined with the term perception of time. We evaluated 158 articles within the inclusion criteria for the purpose of the study. We conclude that research about the holdings of the frontal cortex, parietal, basal ganglia, cerebellum and hippocampus have provided advances in the understanding of the regions related to the perception of time. In neurological and psychiatric disorders, the understanding of time depends on the severity of the diseases and the type of tasks.

Full Text Available Abstract Introduction: Patients with dentofacial deformities may undergo orthodontic or orthodontic-surgical treatment. Both modalities can affect esthetics. Objective: This study aims to evaluate clinical and radiographic changes in exposure of maxillary central incisors occurring after orthognathic surgery for maxillary advancement. Methods: A total of 17 patients who underwent orthognathic surgery for maxillary advancement between September, 2010 and July, 2011 were selected. Exposure of maxillary central incisors was evaluated clinically and by lateral cephalograms. Measurements were taken one week before and three months after surgery. Data were paired in terms of sex, age, nasolabial angle, height and thickness of the upper lip, the amount of maxillary advancement, clinical exposure and inclination of maxillary central incisor by statistical tests (CI 95%. Results: After maxillary advancement, incisor clinical exposure had increased even with relaxed lips and under forced smile. Moreover, there was a mean increase of 23.33% revealed by lateral cephalograms. There was an inverse correlation between upper lip thickness and incisors postsurgical exposure revealed by radiographic images (p = 0.002. Conclusions: Significant changes in the exposure of maxillary central incisors occur after maxillary advancement, under the influence of some factors, especially lip thickness.

Gender and the Telephone: Voice and Emotions Shaping and Gendering Space

Full Text Available In the field of communication studies, the topic of telephony and the gendering of space via voice and emotions has received limited attention. The focus of this article is how telephone conversations are mediated by voice and emotions, which in turn shape and gender social space. The methodology is a collaborative autoethnographic design based on diary notes and memory work. Two central themes emerge from the findings that explain how space becomes gendered when using the telephone: (a the voice and relations of power, and (b the interstices between work, caring, and the telephone. Our findings reveal the central role of work and caring and how these spaces constantly are being traversed and transformed as the mobile phone becomes an important appendage for sensory perceptions of hearing/listening/voice. We argue that these themes point toward the crucial impact of emotions in the construction of multiple and gendered spatialities of telephony.

Lines of resistance: evoking and configuring the theme of resistance in museum displays in Britain around the bicentenary of 1807

Directory of Open Access Journals (Sweden)

Geoffrey Cubitt

2010-11-01

Full Text Available On the basis of an extensive survey of museum displays and exhibitions dealing with slavery and abolition, put on at the time of the 2007 Bicentenary of the Act of Abolition, this article explores, and suggests ways of analysing, the ways in which museums in Britain presented, evoked and interpreted the theme of resistance or rebellion by the enslaved. By recognising the importance of resistance, museums aimed to affirm the agency of the enslaved and to counterbalance the celebratory tendencies of abolitionist historiography; they were also, in some cases, seeking to position themselves less as authoritative purveyors of knowledge than as arenas for the articulation of competing narratives and the negotiation of social and cultural identities. Yet museums’ efforts to foreground the theme of resistance were often limited in character: the importance of the theme was announced, but treatments of it were brief and schematic, dependent on a limited range of materials, and not always convincingly woven into the larger narratives of the exhibition. The article explores some of the reasons for this, before analysing in more detail the presentational strategies of a number of exhibitions which did develop a larger or more complex handling of the theme of resistance. Here the analysis uses a distinction between ‘gestural’ and ‘expository’ presentational emphases to map similarities and differences between these displays, and in particular between the strategies two new and major permanent exhibits opened in 2007: the International Slavery Museum in Liverpool and the re-designed Wilberforce House Museum in Hull.

The Role of Auditory Features Within Slot-Themed Social Casino Games and Online Slot Machine Games.

Bramley, Stephanie; Gainsbury, Sally M

2015-12-01

Over the last few years playing social casino games has become a popular entertainment activity. Social casino games are offered via social media platforms and mobile apps and resemble gambling activities. However, social casino games are not classified as gambling as they can be played for free, outcomes may not be determined by chance, and players receive no monetary payouts. Social casino games appear to be somewhat similar to online gambling activities in terms of their visual and auditory features, but to date little research has investigated the cross over between these games. This study examines the auditory features of slot-themed social casino games and online slot machine games using a case study design. An example of each game type was played on three separate occasions during which, the auditory features (i.e., music, speech, sound effects, and the absence of sound) within the games were logged. The online slot-themed game was played in demo mode. This is the first study to provide a qualitative account of the role of auditory features within a slot-themed social casino game and an online slot machine game. Our results found many similarities between how sound is utilised within the two games. Therefore the sounds within these games may serve functions including: setting the scene for gaming, creating an image, demarcating space, interacting with visual features, prompting players to act, communicating achievements to players, providing reinforcement, heightening player emotions and the gaming experience. As a result this may reduce the ability of players to make a clear distinction between these two activities, which may facilitate migration between games.

Providing Geospatial Education and Real World Applications of Data across the Climate Initiative Themes

Weigel, A. M.; Griffin, R.; Bugbee, K.

2015-12-01

Various organizations such as the Group on Earth Observations (GEO) have developed a structure for general thematic areas in Earth science research, however the Climate Data Initiative (CDI) is addressing the challenging goal of organizing such datasets around core themes specifically related to climate change impacts. These thematic areas, which currently include coastal flooding, food resilience, ecosystem vulnerability, water, transportation, energy infrastructure, and human health, form the core of a new college course at the University of Alabama in Huntsville developed around real-world applications in the Earth sciences. The goal of this course is to educate students on the data available and scope of GIS applications in Earth science across the CDI climate themes. Real world applications and datasets serve as a pedagogical tool that provide a useful medium for instruction in scientific geospatial analysis and GIS software. With a wide range of potential research areas that fall under the rubric of "Earth science", thematic foci can help to structure a student's understanding of the potential uses of GIS across sub-disciplines, while communicating core data processing concepts. The learning modules and use-case scenarios for this course demonstrate the potential applications of CDI data to undergraduate and graduate Earth science students.

Heightened emotional reactivity is one of the core features of borderline personality disorder (BPD). However, recent findings could not provide evidence for a general emotional hyper-reactivity in BPD. The present study examines the emotional responding to self-relevant pictures in dependency of the thematic category (e.g., trauma, interpersonal interaction) in patients with BPD. Therefore, women with BPD (n=31), women with major depression disorder (n=29) and female healthy controls (n=33) rated pictures allocated to thematically different categories (violence, sexual abuse, interaction, non-suicidal self-injury, and suicide) regarding self-relevance, arousal, valence and the urge of non-suicidal self-injury. Compared to both control groups, patients with BPD reported higher self-relevance regarding all categories, but significantly higher emotional ratings only for pictures showing sexual abuse and interpersonal themes. In addition, patients with BPD and comorbid posttraumatic stress disorder showed higher emotional reactivity in violence pictures. Our data provide clear evidence that patients with BPD show a specific emotional hyper-reactivity with respect to schema-related triggers like trauma and interpersonal situations. Future studies are needed to investigate physiological responses to these self-relevant themes in patients with BPD. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

''The Theme was THEME''. This was the headline of The Hydrogen Economy Miami Energy Conference which was the first international conference of this type and which took place in Miami, March 18-20, 1974. For the first time, about 700 participants from all over the western world discussed all the ramifications and aspects of a hydrogen based economy. Non-fossil hydrogen, produced from water by either electrolysis or by direct use of process heat from a nuclear source is a clean, all-synthetic, automatically recyclable, and inexhaustible fuel. It may support the World's future energy requirements beyond the present self limited fossil-fuel era. A large number of papers and news were presented on this conference reflecting this effort. The following article is intended to report on the highlights of the conference and to give a survey on the present state of the art in the hydrogen field. Furthermore, the author includes his own ideas and conclusions predominantly by taking into account the trends in the development of future nuclear reactor systems and symbiotic high-temperature-reactor/breeder strategies being the primary energy input of a hydrogen economy and providing a most promising avenue for solving both the World's energy and environmental (entropy) problems.

Single cell cultures of Drosophila neuroectodermal and mesectodermal central nervous system progenitors reveal different degrees of developmental autonomy.

Science.gov (United States)

Lüer, Karin; Technau, Gerhard M

2009-08-03

The Drosophila embryonic central nervous system (CNS) develops from two sets of progenitor cells, neuroblasts and ventral midline progenitors, which behave differently in many respects. Neuroblasts derive from the neurogenic region of the ectoderm and form the lateral parts of the CNS. Ventral midline precursors are formed by two rows of mesectodermal cells and build the CNS midline. There is plenty of evidence that individual identities are conferred to precursor cells by positional information in the ectoderm. It is unclear, however, how far the precursors can maintain their identities and developmental properties in the absence of normal external signals. To separate the respective contributions of autonomous properties versus extrinsic signals during their further development, we isolated individual midline precursors and neuroectodermal precursors at the pre-mitotic gastrula stage, traced their development in vitro, and analyzed the characteristics of their lineages in comparison with those described for the embryo. Although individually cultured mesectodermal cells exhibit basic characteristics of CNS midline progenitors, the clones produced by these progenitors differ from their in situ counterparts with regard to cell numbers, expression of molecular markers, and the separation of neuronal and glial fate. In contrast, clones derived from individually cultured precursors taken from specific dorsoventral zones of the neuroectoderm develop striking similarities to the lineages of neuroblasts that normally delaminate from these zones and develop in situ. This in vitro analysis allows for the first time a comparison of the developmental capacities in situ and in vitro of individual neural precursors of defined spatial and temporal origin. The data reveal that cells isolated at the pre-mitotic and pre-delamination stage express characteristics of the progenitor type appropriate to their site of origin in the embryo. However, presumptive neuroblasts, once

THE EVOLUTION OF THE KREBS CYCLE: A PROMISING THEME FOR MEANINGFUL BIOCHEMISTRY LEARNING IN BIOLOGY

Full Text Available INTRODUCTION: Evolution has been recognized as a key concept for biologists. In order to motivate biology undergraduates for contents of central energetic metabolism, we addressed the Krebs cycle structure and functions to an evolutionary view. To this end, we created a study guide which contextualizes the emergence of the cyclic pathway, in light of the prokaryotic influence since early Earth anaerobic condition to oxygen rise in atmosphere. OBJECTIVES: The main goal is to highlight the educational potential of the material whose subject is scarcely covered in biochemistry textbooks. MATERIALS AND METHODS: The study guide is composed by three interrelated sections, the problem (Section 1, designed to arouse curiosity, inform and motivate students; an introductory text (Section 2 about life evolution, including early micro-organisms and Krebs cycle emergence, and questions (Section 3 for debate. The activity consisted on a peer discussion session, with instructors tutoring. The questions were designed to foster exchange of ideas in an ever-increasing level of complexity, and cover subjects from early atmospheric conditions to organization of the metabolism along the subsequent geological ages. RESULTS AND DISCUSSION: We noticed that students were engaged and motivated by the task, especially during group discussion. Based on students’ feedbacks and class observations, we learned that the material raised curiosity and stimulated discussion among peers. It brought a historical and purposeful way of dealing with difficult biochemical concepts. CONCLUSIONS: The whole experience suggests that the study guide was a stimulus for broadening comprehension of the Krebs cycle, reinforcing the evolutionary stance as an important theme for biology and biochemistry understanding. On the other hand, we do not underestimate the fact that approaching Krebs cycle from an evolutionary standpoint is a quite complex discussion for the majority of students

Large revealing similarity in multihadron production in nuclear and particle collisions

The dependencies of charged particle pseudorapidity density and transverse energy pseudorapidity density at midrapidity as well as of charged particle total multiplicity on the collision energy and on the number of nucleon participants, or centrality, measured in nucleus-nucleus collisions are studied in the energy range spanning a few GeV to a few TeV per nucleon. The model in which the multiparticle production is driven by the dissipating effective energy of participants is considered. The model extends the earlier proposed approach, combining the constituent quark picture together with Landau relativistic hydrodynamics shown to interrelate the measurements from different types of collisions. Within this model, the dependence of the charged particle pseudorapidity density and transverse energy pseudorapidity density at midrapidity on the number of participants in heavy-ion collisions are found to be well described in terms of the effective energy defined as a centrality-dependent fraction of the collision energy. For both variables the effective energy approach reveals a similarity in the energy dependence obtained for the most central collisions and centrality data in the entire available energy range

2017-01-01

Objective To examine the key themes of positive and negative feedback in patients’ online feedback on NHS (National Health Service) services in England and to understand the specific issues within these themes and how they drive positive and negative evaluation. Design Computer-assisted quantitative and qualitative studies of 228 113 comments (28 971 142 words) of online feedback posted to the NHS Choices website. Comments containing the most frequent positive and negative evaluative words are qualitatively examined to determine the key drivers of positive and negative feedback. Participants Contributors posting comments about the NHS between March 2013 and September 2015. Results Overall, NHS services were evaluated positively approximately three times more often than negatively. The four key areas of focus were: treatment, communication, interpersonal skills and system/organisation. Treatment exhibited the highest proportion of positive evaluative comments (87%), followed by communication (77%), interpersonal skills (44%) and, finally, system/organisation (41%). Qualitative analysis revealed that reference to staff interpersonal skills featured prominently, even in comments relating to treatment and system/organisational issues. Positive feedback was elicited in cases of staff being caring, compassionate and knowing patients’’ names, while rudeness, apathy and not listening were frequent drivers of negative feedback. Conclusions Although technical competence constitutes an undoubtedly fundamental aspect of healthcare provision, staff members were much more likely to be evaluated both positively and negatively according to their interpersonal skills. Therefore, the findings reported in this study highlight the salience of such ‘soft’ skills to patients and emphasise the need for these to be focused upon and developed in staff training programmes, as well as ensuring that decisions around NHS funding do not result in demotivated and rushed staff.

Air-breathing marine animals face a complex set of physical challenges associated with diving that affect the decisions of how to optimize feeding. Baleen whales (Mysticeti) have evolved bulk-filter feeding mechanisms to efficiently feed on dense prey patches. Baleen whales are central place foragers where oxygen at the surface represents the central place and depth acts as the distance to prey. Although hypothesized that baleen whales will target the densest prey patches anywhere in the water column, how depth and density interact to influence foraging behaviour is poorly understood. We used multi-sensor archival tags and active acoustics to quantify Antarctic humpback whale foraging behaviour relative to prey. Our analyses reveal multi-stage foraging decisions driven by both krill depth and density. During daylight hours when whales did not feed, krill were found in deep high-density patches. As krill migrated vertically into larger and less dense patches near the surface, whales began to forage. During foraging bouts, we found that feeding rates (number of feeding lunges per hour) were greatest when prey was shallowest, and feeding rates decreased with increasing dive depth. This strategy is consistent with previous models of how air-breathing diving animals optimize foraging efficiency. Thus, humpback whales forage mainly when prey is more broadly distributed and shallower, presumably to minimize diving and searching costs and to increase feeding rates overall and thus foraging efficiency. Using direct measurements of feeding behaviour from animal-borne tags and prey availability from echosounders, our study demonstrates a multi-stage foraging process in a central place forager that we suggest acts to optimize overall efficiency by maximizing net energy gain over time. These data reveal a previously unrecognized level of complexity in predator-prey interactions and underscores the need to simultaneously measure prey distribution in marine central place forager

Although clinical improvisation continues to be an important focus of music therapy research and practice, less attention has been given to integrating qualitative research in this area. As a result, this knowledge base tends to be contained within specific areas of practice rather than integrated across practices and approaches. This qualitative research synthesis profiles, integrates, and re-presents qualitative research focused on the ways music therapists and clients engage in, and make meaning from, clinical improvisation. Further, as a conduit for broadening dialogues, opening up this landscape fully, and sharing our response to the analysis and interpretation process, we present an arts-informed re-presentation of this synthesis. Following an eight-step methodological sequence, 13 qualitative studies were synthesized. This included reciprocal and refutational processes associated with synthesizing the primary studies, and additional steps associated with an arts-informed representation. Three themes, professional artistry, performing self, and meaning-making, are presented. Each theme is explored and exemplified through the selected articles, and discussed within a larger theoretical framework. An artistic re-presentation of the data is also presented. Music therapists use complex frameworks through which to engage clients in, and make meaning from, improvisational experiences. Artistic representation of the findings offers an added dimension to the synthesis process, challenging our understanding of representation, and thereby advancing synthesis methodology. © the American Music Therapy Association 2017.

Shtaya, Anan; Sadek, Ahmed-Ramadan; Nicoll, James A R; Nader-Sepahi, Ali

2018-03-01

Syringomyelia is a fluid-filled cavitation within the substance of the spinal cord. This condition usually follows a primary pathology that disrupts the normal cerebrospinal fluid circulation or disturbs the microcirculation and cytoarchitecture of the spinal cord parenchyma. However, an etiology of recurrent syringomyelia resulting from an ectopic choroid plexus (CP) has not been discussed. Ectopic CP rests may be found within the central nervous system. Although there has been a single report, describing ectopic intramedullary spinal cord CP, to our knowledge, extra-cranial nonmalignant CP in the central canal of the spinal cord has not been reported. We report CP in the central canal of the spinal cord in a 23-year-old male patient who had developmental delay and diabetes mellitus type I who presented with dissociated sensory changes and muscle wastage predominantly on the right upper and lower limbs. Magnetic resonance imaging demonstrated a multiloculated spinal cord syringomyelia stretching from cervical (C3) to the conus medullaris causing recurrent neurologic deficits. A biopsy of the central canal spinal cord lesion revealed CP. Decompression and syringosubarachnoid shunt insertion stabilized the patient's neurology. Our illustrative case reveals the presence of CP in the central canal of the spinal cord that may suggest a role in the etiology of recurrent syringomyelia. Although management poses a challenge to neurosurgeons, prompt decompression and shunting of the syringomyelia remains a favorable approach with acceptable outcomes. Further investigation into the pathophysiology of central canal CP ectopic causing recurrent syringomyelia and its correlation with spinal cord development may help future treatments.

Eye movement monitoring reveals differential influences of emotion on memory

Directory of Open Access Journals (Sweden)

Lily Riggs

2010-11-01

Full Text Available Research shows that memory for emotional aspects of an event may be enhanced at the cost of impaired memory for surrounding peripheral details. However, this has only been assessed directly via verbal reports which reveal the outcome of a long stream of processing but cannot shed light on how/when emotion may affect the retrieval process. In the present experiment, eye movement monitoring was used as an indirect measure of memory as it can reveal aspects of online memory processing. For example, do emotions modulate the nature of memory representations or the speed with which such memories can be accessed? Participants viewed central negative and neutral scenes surrounded by three neutral objects and after a brief delay, memory was assessed indirectly via eye movement monitoring and then directly via verbal reports. Consistent with the previous literature, emotion enhanced central and impaired peripheral memory as indexed by eye movement scanning and verbal reports. This suggests that eye movement scanning may contribute and/or is related to conscious access of memory. However, the central/peripheral tradeoff effect was not observed in an early measure of eye movement behavior, i.e. participants were faster to orient to a critical region of change in the periphery irrespective of whether it was previously studied in a negative or neutral context. These findings demonstrate emotion’s differential influences on different aspects of retrieval. In particular, emotion appears to affect the detail within, and/or the evaluation of, stored memory representations, but it may not affect the initial access to those representations.

Seismotectonic model of Central Europe

International Nuclear Information System (INIS)

Prochazkova, D.; Roth, Z.

1994-01-01

Earthquakes belong to natural disasters which are associated with tectonic processes in the interior of the Earth. They are extremely devastating in populated areas; they cause human losses and damage personal estates and the environment. To mitigate the potential effects of earthquakes it is necessary that relief and mitigation structures operate following an earthquake, but it is also essential to stimulate and enhance preparedness and prevention. Prevention includes the development of scenarios of potential earthquakes, hazard mapping, formulation of regulations, etc. Preparedness includes the installation and operation of warning systems, establishing communication networks to operate before, during, and after earthquakes. As nuclear technology belongs to high-risk technologies with regard to human health and the environment and its hazard substantially increases in consequence of earthquakes, in the siting of a nuclear plant engineering solutions are generally available to mitigate the potential vibratory effects through design. For the choice of a suitable engineering solution, reliable data must be processed by reliable techniques. The IAEA safety guide of the safety series No. 50-SG-S1(Rev. 1) specifies the demands on data and on their processing and also on the regional seismotectonic model. With a view of this the regional seismotectonic model of Central Europe was created. The paper presents regional geological characteristics of Central Europe and a chronological model of neotectonic movements in Central Europe with specification of neotectonic regional units and their present movements. Moreover, it contains earthquake characteristics for Central Europe and the specification of seismogenic movements. It was found that the genesis of local regions with occurrence of the strongest earthquakes is connected with several movement trends in the last 5 Ma. Six more or less tectonically separate regional units were revealed. The earthquake epicenters often

As the population of people with cancer increases so does the number of patients who take chemotherapy. Majority of them are administered parentally continuously. Implantable central venous catheter device is a good choice for those patients; however, severe complication would occur concerning the devices. Pinch-off syndrome is one of the most severe complications. The authors report a severe case of pinch-off syndrome. The patient with the implantable central venous device could not take chemotherapy because the device occluded. Further examination revealed the transection of the catheter. The transected fragment of the catheter in the heart was successfully removed by using a loop snare placed through the right femoral vein.

Thyroid hormone and the central control of homeostasis.

Science.gov (United States)

Warner, Amy; Mittag, Jens

2012-08-01

It has long been known that thyroid hormone has profound direct effects on metabolism and cardiovascular function. More recently, it was shown that the hormone also modulates these systems by actions on the central autonomic control. Recent studies that either manipulated thyroid hormone signalling in anatomical areas of the brain or analysed seasonal models with an endogenous fluctuation in hypothalamic thyroid hormone levels revealed that the hormone controls energy turnover. However, most of these studies did not progress beyond the level of anatomical nuclei; thus, the neuronal substrates as well as the molecular mechanisms remain largely enigmatic. This review summarises the evidence for a role of thyroid hormone in the central autonomic control of peripheral homeostasis and advocates novel strategies to address thyroid hormone action in the brain on a cellular level.

2017-01-01

We present five cases of cytomegalovirus (CMV) pneumonitis occurring in patients after recent T cell deplete allogeneic stem cell transplantation (AlloHSCT). These cases were complicated by an organising pneumonia (during the recovery period) with a predominantly central peribronchial pattern. All patients presented with evidence of active CMV pneumonitis which was treated successfully with anti-viral therapy but was followed by persistent severe dyspnoea, cough and hypoxia. High resolution computed tomography (HRCT) imaging showed widespread central peribronchial consolidation with traction bronchiectasis. There was a marked clinical and physiological improvement after treatment with systemic corticosteroids. However, in all patients the lung function remained abnormal and in some cases imaging revealed a fibrosing lung disease. These cases represent a previously undescribed central peribronchial pattern of organising pneumonia complicating CMV pneumonitis that can result in chronic lung damage.

Life Themes and Interpersonal Motivational Systems in the Narrative Self-construction

Science.gov (United States)

Veglia, Fabio; Di Fini, Giulia

2017-01-01

What makes unique and unrepeatable individuals is their ability to write their own story attributing meaning, sharing it through narration, giving coherence to the information related to the interpersonal motivational systems, and creating alternative hierarchies to those biologically provided by the genetic code. Through clinical narratives and narrative literature, we can observe the recurrence of specific topics, across time and different cultures. Hence, we wondered whether there are some evolutionary suggestions that guide us in the construction of the narrative-autobiographical contents. In this article we proposed a theoretical-clinical hypothesis about the existence of a biological disposition to identify as fundamental six Life Themes (LTs) that contribute to defining the image of the self and the world: Love, Personal Value, Power, Justice, Truth, and Freedom. Besides the innumerable narratives dependent upon context, there may be many ways of telling stories that, instead, would be reported to these few essential themes. A narrative review of the literature about these concepts follows the systematic explanation of the perspective about the LTs as attractors of meaning. The manuscript considers also the process of co-construction of meanings within the interpersonal relationships and the influences of these on the narratives. In particular, we focused on the importance of episodic and autobiographical memory related to the attachment and significant figures, in the construction of the personal story and the LTs. We also explained the possible clinical implications of the theoretical hypothesis of LTs. Within clinical conversations, the LTs could be expressed rigidly or, otherwise, in a confused way. The lack of narrative integration may lead to the dominance of chaos or rigidity that generates suffering. A better comprehension of the LTs in patients’ narrations could be useful to identify a narrative profile about the areas of greatest suffering

Although itch sensation is an important protective mechanism for animals, chronic itch remains a challenging clinical problem. Itch processing has been studied extensively at the spinal level. However, how itch information is transmitted to the brain and what central circuits underlie the itch-induced scratching behavior remain largely unknown. We found that the spinoparabrachial pathway was activated during itch processing and that optogenetic suppression of this pathway impaired itch-induced scratching behaviors. Itch-mediating spinal neurons, which express the gastrin-releasing peptide receptor, are disynaptically connected to the parabrachial nucleus via glutamatergic spinal projection neurons. Blockade of synaptic output of glutamatergic neurons in the parabrachial nucleus suppressed pruritogen-induced scratching behavior. Thus, our studies reveal a central neural circuit that is critical for itch signal processing.

Our aim was to investigate regional difference in brain activities in response to antiepileptic drug (AED) medications in benign epilepsy with central-temporal spikes (BECTS) using resting-state functional magnetic resonance imaging (fMRI). Fifty-seven patients with BECTS underwent resting-state fMRI scans after receiving either valproic acid (VPA) (n = 15), levetiracetam (LEV) (n = 21), or no medication (n = 21). fMRI regional homogeneity (ReHo) parameter among the three groups of patients were compared and were correlated with total doses of AED in the two medicated groups. Compared with patients on no-medication, patients receiving either VPA or LEV showed decreased ReHo in the central-temporal region, frontal cortex, and thalamus. In particular, the VPA group showed greater ReHo decrease in the thalamus and milder in cortices and caudate heads compared with the LEV group. In addition, the VPA group demonstrated a negative correlation between ReHo values in the central-temporal region and medication dose. Both VPA and LEV inhibit resting-state neural activity in the central-temporal region, which is the main epileptogenic focus of BECTS. VPA reduced brain activity in the cortical epileptogenic regions and thalamus evenly, whereas LEV reduced brain activity predominantly in the cortices. Interestingly, VPA showed a cumulative effect on inhibiting brain activity in the epileptogenic regions in BECTS. (orig.)

2016-12-01

The goal of our study was to track changes in student understanding of the central dogma of molecular biology before and after taking a genetics course. Concept maps require the ability to synthesize new information into existing knowledge frameworks, and so the hypothesis guiding this study was that student performance on concept maps reveals specific central dogma misconceptions gained, lost, and retained by students. Students in a genetics course completed pre- and posttest concept mapping tasks using terms related to the central dogma. Student maps increased in complexity and validity, indicating learning gains in both content and complexity of understanding. Changes in each of the 351 possible connections in the mapping task were tracked for each student. Our students did not retain much about the central dogma from their introductory biology courses, but they did move to more advanced levels of understanding by the end of the genetics course. The information they retained from their introductory courses focused on structural components (e.g., protein is made of amino acids) and not on overall mechanistic components (e.g., DNA comes before RNA, the ribosome makes protein). Students made the greatest gains in connections related to transcription, and they resolved the most prior misconceptions about translation. These concept-mapping tasks revealed that students are able to correct prior misconceptions about the central dogma during an intermediate-level genetics course. From these results, educators can design new classroom interventions to target those aspects of this foundational principle with which students have the most trouble.

Abstract This paper is motivated by the need to discuss the quality of life as a part of the background for devising environmental strategies. When environmental strategies are devised, it is often more or less tacitly assumed that we should try to avoid measures that imply a decrease in the level....... The critical perspective is developed by dealing with welfare or the quality of life: what does it mean to have a good life? On the basis of this discussion, the relationship between consumption and welfare can then be assessed. The approach to the discussion of the quality of life in this paper is first...... with the different themes in the discussion of the quality of life. The point of departure is taken in some critical considerations related to the traditional conceptualization of welfare. After that, some inspiration from the debate on basic needs is outlined and supplemented with some reflections on the dual...

Individuals benefit from occupying central roles in social networks, but little is known about the psychological traits that predict centrality. Across four college freshman dorms ( n = 193), we characterized individuals with a battery of personality questionnaires and also asked them to nominate dorm members with whom they had different types of relationships. This revealed several social networks within dorm communities with differing characteristics. In particular, additional data showed that networks varied in the degree to which nominations depend on ( i ) trust and ( ii ) shared fun and excitement. Networks more dependent upon trust were further defined by fewer connections than those more dependent on fun. Crucially, network and personality features interacted to predict individuals' centrality: people high in well-being (i.e., life satisfaction and positive emotion) were central to networks characterized by fun, whereas people high in empathy were central to networks characterized by trust. Together, these findings provide network-based corroboration of psychological evidence that well-being is socially attractive, whereas empathy supports close relationships. More broadly, these data highlight how an individual's personality relates to the roles that they play in sustaining their community.

Central Equatorial Pacific Experiment (CEPEX)

Energy Technology Data Exchange (ETDEWEB)

1993-01-01

The Earth's climate has varied significantly in the past, yet climate records reveal that in the tropics, sea surface temperatures seem to have been remarkably stable, varying by less than a few degrees Celsius over geologic time. Today, the large warm pool of the western Pacific shows similar characteristics. Its surface temperature always exceeds 27[degree]C, but never 31[degree]C. Heightened interest in this observation has been stimulated by questions of global climate change and the exploration of stabilizing climate feedback processes. Efforts to understand the observed weak sensitivity of tropical sea surface temperatures to climate forcing has led to a number of competing ideas about the nature of this apparent thermostat. Although there remains disagreement on the processes that regulate tropical sea surface temperature, most agree that further progress in resolving these differences requires comprehensive field observations of three-dimensional water vapor concentrations, solar and infrared radiative fluxes, surface fluxes of heat and water vapor, and cloud microphysical properties. This document describes the Central Equatorial Pacific Experiment (CEPEX) plan to collect such observations over the central equatorial Pacific Ocean during March of 1993.

New scientific, technological and legal developments, particularly the introduction of national databases for DNA and fingerprints, have led to increased use of forensic science in the investigation of crime. There is an assumption, and in some instances specific assertions, that such developments bring improvements either in broad criminal justice terms or more narrowly in terms of economic or practical efficiencies. The underlying presumption is that the new technological opportunities will be understood and effectively implemented. This research investigates whether such increases in activity have also been accompanied by improvements in the effective use of forensic science. A systematic review of thirty-six reports published (predominantly in England and Wales) since the 1980s, which have considered the use of forensic science in the investigation of volume crimes, was carried out. These reports have identified a number of recurrent themes that influenced how effectively forensic science was used in investigations. The themes identified included forensic knowledge and training of investigators, communication and information exchange between specialists and investigators, timeliness of forensic results, interagency relationships and deployment of crime scene examiner resources. The research findings suggest that these factors continue to hinder the effective use of forensic science despite technological advances and this paper considers their potential causes. © 2013.

The central systems of air conditioning are widely used in air conditioning production for several reasons among which excel: 1) Better aesthetic of the building, 2) Less noise in the air conditioning premises and 3) Greater yield of the consumed energy. This is indeed the third reason in which this paper will try to contribute with elements that will allow reveal the problem and to identify some possible causes that originate it. The centralized systems of air conditioning must produce conditioned air with lesser power cost than the individual systems, it is that saving which allows to recover an investment that normally surpasses them in 3 to 5 times. Nevertheless, the real numbers do not demonstrate that. [Spanish] Los sistemas centrales de climatizacion son ampliamente usados en la produccion de aire acondicionado por varias razones entre las que sobresalen: 1) Mejor estetica del edificio, 2) Menor ruido en los locales climatizados y 3) Mayor rendimiento de la energia consumida. Es precisamente la tercera razon en la cual este trabajo intentara aportar elementos que permitan develar el problema e identificar algunas posibles causas que lo originan. Los sistemas centralizados de climatizacion deben producir aire acondicionado con un menor gasto energetico que los sistemas individuales, es precisamente ese ahorro lo que permite recuperar una inversion que normalmente los supera en 3 a 5 veces. Sin embargo, los numeros reales no demuestran eso.

The ultraviolet B (UVB) sunburn model was characterized with a comprehensive battery of quantitative sensory testing (QST). Primary hyperalgesia in UVB-irradiated skin and secondary hyperalgesia in adjacent nonirradiated skin were studied in 22 healthy subjects 24h after irradiation with UVB at 3-fold minimal erythema dose of a skin area 5 cm in diameter at the thigh and compared to mirror-image contralateral control areas. The time course of hyperalgesia over 96 h was studied in a subgroup of 12 subjects. Within the sunburn area, cold hyperesthesia (P=.01), profound generalized hyperalgesia to heat (Psunburn was surrounded by large areas of pinprick hyperalgesia (mean±SEM, 218±32 cm(2)) and a small rim of dynamic mechanical allodynia but no other sensory changes. Although of smaller magnitude, secondary hyperalgesia and dynamic mechanical allodynia adjacent to the UVB-irradiated area were statistically highly significant. Primary and secondary hyperalgesia developed in parallel within hours, peaked after 24-32 h, and lasted for more than 96 h. These data reveal that the UVB sunburn model activates a broad spectrum of peripheral and central sensitization mechanisms and hence is a useful human surrogate model to be used as a screening tool for target engagement in phases 1 and 2a of drug development.

Occupational radiation exposure in Central and Eastern European countries - ESOREX EAST -. Proceedings

International Nuclear Information System (INIS)

Frasch, G.; Anatschkowa, E.

1999-02-01

On behalf of the European Commission, the BfS is currently executing a project entitled 'European Study of Occupational Radiation Exposure - ESOREX'. The project consists of several surveys executed in the Member States of the European Union, furthermore in Iceland, Norway and Switzerland. In each of these countries the - 1. administrative systems used to register individual occupational radiation exposure, - 2. numbers and dose distributions of occupationally radiation exposed persons in 1995 are surveyed. The aim is to describe and compare the administrative structures of the various national registration systems and the distributions of the workers and their doses. It shall identify the differences between the states and analyse the possibilities for a European harmonization. Because of the intention of numerous Central and Eastern European countries to join the European Community, the harmonization theme is also of considerable importance for these countries. The workshop served the preparing works to execute the ESOREX study also in ten Central and Eastern European countries. In order to establish the necessary contacts and to prepare the co-operation with the respective institutions of these states, the BfS organised, together with the State Office for Nuclear Safety of the Czech Republic, an international introductory workshop in Prague in September 1998. The proceedings reflect the presentations of the participants and the results of the discussions. (orig.) [de

A Novel Entropy-Based Centrality Approach for Identifying Vital Nodes in Weighted Networks

Directory of Open Access Journals (Sweden)

Tong Qiao

2018-04-01

Full Text Available Measuring centrality has recently attracted increasing attention, with algorithms ranging from those that simply calculate the number of immediate neighbors and the shortest paths to those that are complicated iterative refinement processes and objective dynamical approaches. Indeed, vital nodes identification allows us to understand the roles that different nodes play in the structure of a network. However, quantifying centrality in complex networks with various topological structures is not an easy task. In this paper, we introduce a novel definition of entropy-based centrality, which can be applicable to weighted directed networks. By design, the total power of a node is divided into two parts, including its local power and its indirect power. The local power can be obtained by integrating the structural entropy, which reveals the communication activity and popularity of each node, and the interaction frequency entropy, which indicates its accessibility. In addition, the process of influence propagation can be captured by the two-hop subnetworks, resulting in the indirect power. In order to evaluate the performance of the entropy-based centrality, we use four weighted real-world networks with various instance sizes, degree distributions, and densities. Correspondingly, these networks are adolescent health, Bible, United States (US airports, and Hep-th, respectively. Extensive analytical results demonstrate that the entropy-based centrality outperforms degree centrality, betweenness centrality, closeness centrality, and the Eigenvector centrality.

Failure of eruption of primary teeth can be considered rare, especially in maxillary anterior teeth. The problem can be either mechanical obstruction of eruption or a failure of the eruption mechanism. This case report presents failure of eruption of the maxillary right deciduous central incisor in a 4-year-old girl. The unerupted primary tooth was removed surgically. The histological finding revealed fibroma with reactive giant cells. Periodic follow-up visits were advised to monitor the developing dentition and to ensure enough space for the permanent incisor.

Single cell cultures of Drosophila neuroectodermal and mesectodermal central nervous system progenitors reveal different degrees of developmental autonomy

Directory of Open Access Journals (Sweden)

Technau Gerhard M

2009-08-01

Full Text Available Abstract Background The Drosophila embryonic central nervous system (CNS develops from two sets of progenitor cells, neuroblasts and ventral midline progenitors, which behave differently in many respects. Neuroblasts derive from the neurogenic region of the ectoderm and form the lateral parts of the CNS. Ventral midline precursors are formed by two rows of mesectodermal cells and build the CNS midline. There is plenty of evidence that individual identities are conferred to precursor cells by positional information in the ectoderm. It is unclear, however, how far the precursors can maintain their identities and developmental properties in the absence of normal external signals. Results To separate the respective contributions of autonomous properties versus extrinsic signals during their further development, we isolated individual midline precursors and neuroectodermal precursors at the pre-mitotic gastrula stage, traced their development in vitro, and analyzed the characteristics of their lineages in comparison with those described for the embryo. Although individually cultured mesectodermal cells exhibit basic characteristics of CNS midline progenitors, the clones produced by these progenitors differ from their in situ counterparts with regard to cell numbers, expression of molecular markers, and the separation of neuronal and glial fate. In contrast, clones derived from individually cultured precursors taken from specific dorsoventral zones of the neuroectoderm develop striking similarities to the lineages of neuroblasts that normally delaminate from these zones and develop in situ. Conclusion This in vitro analysis allows for the first time a comparison of the developmental capacities in situ and in vitro of individual neural precursors of defined spatial and temporal origin. The data reveal that cells isolated at the pre-mitotic and pre-delamination stage express characteristics of the progenitor type appropriate to their site of origin in

Full Text Available China's footprints in Afghanistan are vied by many, both, friends and rivals as it cautiously reveals its geostrategic goals. It would like to emulate the African and Central Asian success story in Afghanistan as well, which is not terra incognito. Afghanistan has been the fulcrum of geopolitical balance of power during the Cold war days. China's Afghanistan policy (CAP is marked by its insecurities of terrorism, extremism and separatism in Xinjiang province. It has heavily invested in procuring Central Asian energy resources. Both, the concerns go well in formulation of CAP. However, the presence of the US and Russia make the scenario competitive, where its ‘Peaceful Rise’ may be contested. Besides, China sees South Asian Region as its new Geoeconomic Frontier. All these concerns get factored into CAP. It remains to be seen what options partake in CAP, as China prepares for durable presence in Afghanistan in the long run.

Congdon, J G; Magilvy, J K

2001-01-01

The culture and diversity of rural life and limitations of rural health systems to meet the changing health needs of an aging population lead to problems of obtaining appropriate care in rural America. In a program of nursing research involving three ethnographic studies in rural Colorado, transitions of older adults across differing levels of heath care were explored. The sample totaled 425 participants, of whom 25% were Hispanic. Five major themes emerged: circles of formal and informal care; integration of faith, spirituality, and family with health status; crisis nature of health care transitions; nursing homes as a housing option; and changing spirit of traditional rural nursing. Recommendations for providers included making their practices congruent with rural culture, being fully informed of available resources, facilitating acceptable health care decisions, and integrating physical, mental, and spiritual health care for elders and their families.

While Patient and Public Involvement (PPI) is encouraged throughout the research process, engagement is typically limited to intervention design and post-analysis stages. There are few approaches to participatory data analyses within complex health interventions. Using qualitative data from a feasibility randomised controlled trial (RCT), this proof-of-concept study tests the value of a new approach to participatory data analysis called Participatory Theme Elicitation (PTE). Forty excerpts were given to eight members of a youth advisory PPI panel to sort into piles based on their perception of related thematic content. Using algorithms to detect communities in networks, excerpts were then assigned to a thematic cluster that combined the panel members' perspectives. Network analysis techniques were also used to identify key excerpts in each grouping that were then further explored qualitatively. While PTE analysis was, for the most part, consistent with the researcher-led analysis, young people also identified new emerging thematic content. PTE appears promising for encouraging user led identification of themes arising from qualitative data collected during complex interventions. Further work is required to validate and extend this method. ClinicalTrials.gov, ID: NCT02455986 . Retrospectively Registered on 21 May 2015.

Child injury control: trends, themes, and controversies.

Science.gov (United States)

Johnston, Brian D; Ebel, Beth E

2013-01-01

Injury is a major cause of morbidity and mortality among US children, and an important driver of health status globally. Despite its enormous burden, injury is preventable. Over the last 10 years, significant progress has been made in the reduction of unintentional injury among US children. However, aggregate trends mask important disparities by age group, region, and injury mechanism. Basic and translation research is needed to develop and test prevention strategies to address these new or recalcitrant problems. Motor vehicle occupant injury has fallen to historic lows, but challenges remain in protecting novice drivers and managing the distraction of new technologies. Injury to pedestrians has also declined, but likely as a result of decreased exposure as fewer children walk. This calls for a broader public health perspective to promote activity while enhancing safety. Deaths due to drowning are common and illustrate the difficulty in measuring and promoting appropriate supervision. Environmental modification and use of protective products may be a more appropriate response. Concussion in sport is another challenging issue: public health laws promote identification and appropriate management of concussed athletes, but less progress has been made on primary prevention of these injuries. Unintentional poisoning is on the rise, attributable to misuse of, and overdose with, prescription opioids. Injury deaths to infants are also increasing. This trend is driven in part by better death investigation that classifies more sleep-related deaths as suffocation events. Finally, we examine a sample of cross-cutting themes and controversies in injury control that might be amenable to empiric evaluation. Copyright © 2013 Academic Pediatric Association.

An estimated 200,000 Americans suffer central line-associated bloodstream infections (CLABs) each year, with 15%-20% mortality. Two intensive care units (ICUs) redefined the processes of care through system redesign to deliver reliable outcomes free of the variations that created the breeding ground for infection. The ICUs, comprising 28 beds at Allegheny General Hospital, employed the principles of the Toyota Production System adapted to health care--Perfecting Patient Care--and applied them to central line placement and maintenance. Intensive observations, which revealed multiple variances from established practices, and root cause analyses of all CLABs empowered the workers to implement countermeasures designed to eliminate the defects in the processes of central line placement and maintenance. New processes were implemented within 90 days. Within a year CLABs decreased from 49 to 6 (10.5 to 1.2 infections/1,000 line-days), and mortalities from 19 to 1 (51% to 16%), despite an increase in the use of central lines and number of line-days. These results were sustained during a 34-month period. CLABs are not an inevitable product of complex ICU care but the result of highly variable and therefore unreliable care delivery that predisposes to infection.

We herein report a case of central diabetes insipidus complicated with thyroid storm. A middle-aged woman who was receiving treatment for Graves' disease suddenly complained of polydipsia, polyuria and general fatigue. Laboratory tests showed hyperthyroidism, hypernatremia, hypoosmolar urine and a decreased plasma vasopressin level. The occurrence of central diabetes insipidus with hyperthyroidism was revealed on the basis of pituitary magnetic resonance imaging, a water deprivation test and a desmopressin test. The clinical co-existence of diabetes insipidus and hyperthyroidism is very rare; however, the complication should be considered when hypernatremia and/or dehydration progress in patients with Graves's disease as a common autoimmune-related etiology.

Central Asia in the Iranian geopolitical imagination

Directory of Open Access Journals (Sweden)

Edward Wastnidge

2017-02-01

Full Text Available This article charts Iran’s relations with Central Asia following the break-up of the Soviet Union in 1991. This event gave Iran a new set of neighbours to the north, and this came at a time when Iran was undergoing changes in the direction of its foreign policy from radical idealistic goals, such as the export of the Islamic Revolution, to more pragmatic aims, including giving priority to its own national interests and pursuing good neighbourly relations. Since 1991, Iran has attempted to develop relations towards the Central Asian states, both bilaterally and through various regional fora. Iran’s actions have been based, in part, on a greater commitment to regionalism that has been evident in Iranian foreign policy since the early 1990s. This has focused on cultivating economic, infrastructural and cultural links with the region, rather than any form of ideological crusade, and has helped reduce Iran’s international isolation. Following a historical contextualisation and explanation of the place that the lands of Central Asia hold in the Iranian geopolitical imagination, the article explores the key concerns of Iran in the region. It will examine Iran’s position on what it perceives as being the key issues shaping its Central Asian diplomacy, namely regional economic cooperation, pipeline politics, the status of the Caspian Sea, security cooperation and cultural diplomacy. This provides a revealing case study of how Iran perceives itself as a vital player in the region, seeking to emphasise the benefits of its geostrategic location, relative stability, and increasing international role following the nuclear deal.

2014-07-01

One of the most serious problems for tuberculosis (TB) control is non-adherence to TB treatment. We studied the factors influencing non-adherence to TB treatment in Indonesia to inform TB treatment adherence strategies. We con- ducted semi-structured interviews with non-adherent patients and key informants in Jepara, Central Java, Indonesia. Three major themes were found in reasons for non-adherence to TB treatment: 1) knowledge about TB, 2) knowledge about TB treatment and 3) choosing and changing a health care treatment facility. Respondents had an inadequate knowledge about TB and its treatment. Feeling healthy and having financial problems were the most common reasons for TB treatment non-adherence. Respondents sought treatment from many different health care providers, and often changed the treatment facility location. TB treatment adherence might improve by providing better education about the disease and its treatment to those undergoing treatment. Providing information about where to receive treatment and that treatment is free could also improve compliance.

Callender, Valerie D; Wright, Dakara Rucker; Davis, Erica C; Sperling, Leonard C

2012-09-01

Central centrifugal cicatricial alopecia is the most common form of cicatricial alopecia in African American women. Treatment options are limited and mostly aimed at halting further hair loss but rarely result in hair regrowth. Therefore, it is important to recognize early clinical signs, perform a confirmatory biopsy, and begin treatment promptly. We have observed that hair breakage may be a key sign of early central centrifugal cicatricial alopecia, and this association is not clearly described in the literature. Nine patients with hair breakage on the vertex with or without scalp symptoms underwent scalp biopsies as part of their evaluation. Of these, 8 had histologic samples adequate for complete interpretation: 5 specimens (63%) showed histologic changes typical of central centrifugal cicatricial alopecia, with 1 of these showing advanced end-stage changes of cicatricial alopecia. Two (25%) revealed premature desquamation of the inner root sheath as the sole finding suggestive of early central centrifugal cicatricial alopecia and 1 (13%) was normal. Although hair breakage can have multiple causes, early central centrifugal cicatricial alopecia must be considered in the differential diagnosis, particularly in women of African ancestry. Histologic evaluation may reveal early or late findings that can help establish the diagnosis.

Central depression in nucleonic densities: Trend analysis in the nuclear density functional theory approach

Science.gov (United States)

Schuetrumpf, B.; Nazarewicz, W.; Reinhard, P.-G.

2017-08-01

Background: The central depression of nucleonic density, i.e., a reduction of density in the nuclear interior, has been attributed to many factors. For instance, bubble structures in superheavy nuclei are believed to be due to the electrostatic repulsion. In light nuclei, the mechanism behind the density reduction in the interior has been discussed in terms of shell effects associated with occupations of s orbits. Purpose: The main objective of this work is to reveal mechanisms behind the formation of central depression in nucleonic densities in light and heavy nuclei. To this end, we introduce several measures of the internal nucleonic density. Through the statistical analysis, we study the information content of these measures with respect to nuclear matter properties. Method: We apply nuclear density functional theory with Skyrme functionals. Using the statistical tools of linear least square regression, we inspect correlations between various measures of central depression and model parameters, including nuclear matter properties. We study bivariate correlations with selected quantities as well as multiple correlations with groups of parameters. Detailed correlation analysis is carried out for 34Si for which a bubble structure has been reported recently, 48Ca, and N =82 , 126, and 184 isotonic chains. Results: We show that the central depression in medium-mass nuclei is very sensitive to shell effects, whereas for superheavy systems it is firmly driven by the electrostatic repulsion. An appreciable semibubble structure in proton density is predicted for 294Og, which is currently the heaviest nucleus known experimentally. Conclusion: Our correlation analysis reveals that the central density indicators in nuclei below 208Pb carry little information on parameters of nuclear matter; they are predominantly driven by shell structure. On the other hand, in the superheavy nuclei there exists a clear relationship between the central nucleonic density and symmetry energy.

To prospectively assay the vestibular and oculomotor systems of blast-exposed service members with traumatic brain injury (TBI). Prospective, nonblinded, nonrandomized descriptive study. Tertiary care facility (Department of Defense Medical Center). Twenty-four service members recovering from blast-related TBI sustained in Iraq or Afghanistan. Focused history and physical, videonystagmography (VNG), rotational chair, cervical vestibular-evoked myogenic potentials, computerized dynamic posturography, and self-report measures. Vestibular testing confirms a greater incidence of vestibular and oculomotor dysfunction in symptomatic (vestibular-like dizziness) personnel with blast-related TBI relative to asymptomatic group members. VNG in the symptomatic group revealed abnormal nystagmus or oculomotor findings in 6 of 12 subjects tested. Similarly, rotational chair testing in this group revealed evidence of both peripheral (4/12) and central (2/12) vestibular pathology. By contrast, the asymptomatic group revealed less vestibular impairment with 1 of 10 rotational chair abnormalities. The asymptomatic group was further characterized by fewer aberrant nystagmus findings (4/12 abnormal VNGs). Computerized dynamic posturography testing revealed no significant differences between groups. Self-report measures demonstrated differences between groups. Vestibular function testing confirms a greater incidence of peripheral vestibular hypofunction in dizzy service members with blast-related TBI relative to those who are asymptomatic. Additionally, oculomotor abnormalities and/or nystagmus consistent with central involvement were present in 10 of the 24 study participants tested. The precise cause of these findings remains unknown.

Full Text Available Abstract Background Similarities as well as differences in higher order chromatin arrangements of human cell types were previously reported. For an evolutionary comparison, we now studied the arrangements of chromosome territories and centromere regions in six mouse cell types (lymphocytes, embryonic stem cells, macrophages, fibroblasts, myoblasts and myotubes with fluorescence in situ hybridization and confocal laser scanning microscopy. Both species evolved pronounced differences in karyotypes after their last common ancestors lived about 87 million years ago and thus seem particularly suited to elucidate common and cell type specific themes of higher order chromatin arrangements in mammals. Results All mouse cell types showed non-random correlations of radial chromosome territory positions with gene density as well as with chromosome size. The distribution of chromosome territories and pericentromeric heterochromatin changed during differentiation, leading to distinct cell type specific distribution patterns. We exclude a strict dependence of these differences on nuclear shape. Positional differences in mouse cell nuclei were less pronounced compared to human cell nuclei in agreement with smaller differences in chromosome size and gene density. Notably, the position of chromosome territories relative to each other was very variable. Conclusion Chromosome territory arrangements according to chromosome size and gene density provide common, evolutionary conserved themes in both, human and mouse cell types. Our findings are incompatible with a previously reported model of parental genome separation.

A 66-year-old man presented with deteriorated bradykinesia, gait disturbance, disorientation, and urinary incontinence for three weeks. Magnetic resonance imaging (MRI) showed dilatation of the ventricles. Cerebrospinal fluid (CSF) examination demonstrated lymphocytic pleocytosis, elevation of protein levels, and decreased of glucose levels. A gadolinium-enhanced MRI revealed lesions in the ventricular wall and choroid plexus, mimicking ventriculitis. No evidence of bacterial, fungal, mycobacterial, or viral infections were observed in the CSF. Flow cytometry of CSF showed predominance of CD20+, λ+ cells. PCR examination of CSF revealed positive IgH gene rearrangement, suggesting B cell lymphoma. Endoscopic brain biopsy showed diffuse large B cell lymphoma. As the patient had no evidence of lymphoma in the other organs, we made a diagnosed of primary central nervous system lymphoma (PCNSL). A limited intraventricular spread of PCNSL is rare but important as one of differential diagnosis of ventriculitis.

Radioactivity And Nuclear Themes In Croatian Popular Culture

International Nuclear Information System (INIS)

Franic, Z.; Franic, S.

2015-01-01

Popular culture refers to the entirety of ideas, perspectives, attitudes, behaviours, ways of communication, cultural and artistic products, (visual, auditory, written, etc.) as well as other phenomena in the real or virtual world within mainstream culture. Heavily influenced by mass media, this collection of ideas permeates the everyday lives of society. In the so-called atomic age, which corresponds to the cold war period, stylistic coloration and application of the concepts of radiation that have persisted in everyday life to this day can be classified into four main groups of radiological-nuclear themes: monsters and mutants associated with radiation, nuclear accidents, nuclear terrorism and nuclear optimism. This paper discusses some examples relating to radioactivity, radiation and nuclear topics in Croatian popular culture, with special reference to the mass media, including some Internet portals. In Croatian mass media, like in other cultures, radiation and nuclear metaphors symbolize something scary and completely incomprehensible. However, further systematic research would be needed to analyse and explain all of the stereotypes in more detail. Results would be useful in creating a more effective way for informing the general public about the effects and use of radiation and nuclear technology, which is expected to play a far greater role in solving numerous problems dealing with energy supply, medicine, etc. in the near future. It should be noted that nowadays the collective public fears shift from radiation to other global threats such as climate change, genetically modified organisms, global terrorism and others.

Sport as the Pragmatic Determiner, Motif and Theme of Pindaric Odes

Directory of Open Access Journals (Sweden)

Brane Senegačnik

2015-07-01

Full Text Available The vast majority of Pindar’s integrally preserved poetry is linked to sport: his epinicia, collected in four volumes, are dedicated to victors in various sporting disciplines at the four pan-Hellenic games. This is more than an external pragmatic circumstance: an obligatory constituent of the epinicium is the victor’s genealogy, often accompanied by a detailed account of the victor’s feat and career as well as the sporting achievements of his ancestors. Sporting success is a peak of human life, worth any exertion or cost, but even so it cannot lead to transcendence: it is a single moment blending into the shadow of transience. The sporting victory motif thus expands into the theme of human identity, which is in Pindar’s religious world crucially determined by man’s closeness or semblance to the gods on the one hand and the insurmountable difference on the other.

We have generated a more than 500 km long postseismic deformation rate map and cumulative displacement time series in the central Bayankala Block of the Tibetan Plateau using ENVISAT/ASAR data from 2003 to 2010 by the π-RATE stacking algorithm. This rate map spans a period of ∼7.2 years and reveals that postseismic motion of 2001 Kokoxili earthquake exhibits a striking signal, dominating crustal deformation of the central Bayankala Block with a cross-fault magnitude ∼9-11 mm/yr in line of sight (LOS) (∼93.1°E). The southern and northern parts of the postseismic deformation field exhibit different patterns and variable magnitudes, reflecting asymmetry of the displacement distribution. Postseismic motion affects eastward extrusion of the central Bayankala Block, which reaches ∼15 km north of the Ganzi-Yushu fault. To further investigate viscoelastic relaxation of the lower crust in this area after approximately two years, E-M, E-M-M and E-S models are constructed. The result shows that the best fit viscosity for the lower crust is about 1 × 1019 Pa·s. Comparison between cumulative displacements resolved by these three models shows that viscoelastic relaxation of the lower crust makes the most significant contribution to postseismic stress relaxation after 2001 event.

Full Text Available Dunia Fantasi (Dufan located in Taman Impian Jaya Ancol is one leading recreational unit with specific characteristics as a theme park. A research was done towards with service quality and implementation of experiential marketing applied in Dufan using path analysis. Experiential marketing was studied to have a direct effect, positive and significant impact on customer attitude variables. The basic objective of this research is to determine the effect of service quality and implementation of experiential marketing to customer attitude and its impact on customer intention of Dufan. Data collection was conducted through questionnaire given to Dufan visitors. From the results of data analysis we found that service quality has not significantly influenced customer’s attitude. The study revealed that the direct effect between experiential marketing and customer intention is 'strong’. As a subsequent finding, service quality has not given a significant effect on customer intention. However, experiential marketing was found having an indirect influence on customer intention mediated by attitude, in which the results of the study suggested that the indirect effect is 'strong'. Eventually, customer attitude has a direct positive and significant impact on customer intention variables. The direct influence of customer attitude to customer intention in Fantasy World,was 'strong'.

Geospatial Computer Vision has become one of the most prevalent emerging fields of investigation in Earth Observation in the last few years. In this theme issue, we aim at showcasing a number of works at the interface between remote sensing, photogrammetry, image processing, computer vision and machine learning. In light of recent sensor developments - both from the ground as from above - an unprecedented (and ever growing) quantity of geospatial data is available for tackling challenging and urgent tasks such as environmental monitoring (deforestation, carbon sequestration, climate change mitigation), disaster management, autonomous driving or the monitoring of conflicts. The new bottleneck for serving these applications is the extraction of relevant information from such large amounts of multimodal data. This includes sources, stemming from multiple sensors, that exhibit distinct physical nature of heterogeneous quality, spatial, spectral and temporal resolutions. They are as diverse as multi-/hyperspectral satellite sensors, color cameras on drones, laser scanning devices, existing open land-cover geodatabases and social media. Such core data processing is mandatory so as to generate semantic land-cover maps, accurate detection and trajectories of objects of interest, as well as by-products of superior added-value: georeferenced data, images with enhanced geometric and radiometric qualities, or Digital Surface and Elevation Models.

The butyrophilin 3 (BTN3) receptors are implicated in the T lymphocytes regulation and present a wide plasticity in mammals. In order to understand how these genes have been diversified, we studied their evolution and show that the three human BTN3 are the result of two successive duplications in Primates and that the three genes are present in Hominoids and the Old World Monkey groups. A thorough phylogenetic analysis reveals a concerted evolution of BTN3 characterized by a strong and recurrent homogenization of the region encoding the signal peptide and the immunoglobulin variable (IgV) domain in Hominoids, where the sequences of BTN3A1 or BTN3A3 are replaced by BTN3A2 sequence. In human, the analysis of the diversity of these genes in 1683 individuals representing 26 worldwide populations shows that the three genes are polymorphic, with more than 46 alleles for each gene, and marked by extreme homogenization of the IgV sequences. The same analysis performed for the BTN2 genes shows also a concerted evolution; however, it is not as strong and recurrent as for BTN3. This study shows that BTN3 receptors are marked by extreme concerted evolution at the IgV domain and that BTN3A2 plays a central role in this evolution.

Integrating Environmental and Human Health Databases in the Great Lakes Basin: Themes, Challenges and Future Directions

Full Text Available Many government, academic and research institutions collect environmental data that are relevant to understanding the relationship between environmental exposures and human health. Integrating these data with health outcome data presents new challenges that are important to consider to improve our effective use of environmental health information. Our objective was to identify the common themes related to the integration of environmental and health data, and suggest ways to address the challenges and make progress toward more effective use of data already collected, to further our understanding of environmental health associations in the Great Lakes region. Environmental and human health databases were identified and reviewed using literature searches and a series of one-on-one and group expert consultations. Databases identified were predominantly environmental stressors databases, with fewer found for health outcomes and human exposure. Nine themes or factors that impact integration were identified: data availability, accessibility, harmonization, stakeholder collaboration, policy and strategic alignment, resource adequacy, environmental health indicators, and data exchange networks. The use and cost effectiveness of data currently collected could be improved by strategic changes to data collection and access systems to provide better opportunities to identify and study environmental exposures that may impact human health.

Centralized vs. Decentralized Nursing Stations: An Evaluation of the Implications of Communication Technologies in Healthcare.

Bayramzadeh, Sara; Alkazemi, Mariam F

2014-01-01

This study aims to explore the relationship between the nursing station design and use of communication technologies by comparing centralized and decentralized nursing stations. The rapid changes in communication technologies in healthcare are inevitable. Communication methods can change the way occupants use a space. In the meantime, decentralized nursing stations are emerging as a replacement for the traditional centralized nursing stations; however, not much research has been done on how the design of nursing stations can impact the use of communication technologies. A cross sectional study was conducted using an Internet-based survey among registered nurses in a Southeastern hospital in the United States. Two units with centralized nursing stations and two units with decentralized nursing stations were compared in terms of the application of communication technologies. A total of 70 registered nurses completed the survey in a 2-week period. The results revealed no significant differences between centralized and decentralized nursing stations in terms of frequency of communication technologies used. However, a difference was found between perception of nurses toward communication technologies and perceptions of the use of communication technologies in decentralized nursing stations. Although the study was limited to one hospital, the results indicate that nurses hold positive attitudes toward communication technologies. The results also reveal the strengths and weaknesses of each nursing station design with regard to communication technologies. Hospital, interdisciplinary, nursing, technology, work environment.
