    Dearborn, David S. P.; Bauer, Brian S.

    Half a millennium ago in the central Andes of Peru, the movements of the sun, moon, and stars were watched and interpreted by the Inca. The astronomical observations made in and near the former capital, Cuzco, formed the nuclei of the most important public rituals of the empire. As the regulator of time, the ruling Inca scheduled the rituals that bound this society together. In this article, we review the major astronomical observations that were made by the Inca and discuss their importance in defining the ritual calendar.

  4. INCA- INTERACTIVE CONTROLS ANALYSIS

    Science.gov (United States)

    Bauer, F. H.

    1994-01-01

    The Interactive Controls Analysis (INCA) program was developed to provide a user friendly environment for the design and analysis of linear control systems, primarily feedback control systems. INCA is designed for use with both small and large order systems. Using the interactive graphics capability, the INCA user can quickly plot a root locus, frequency response, or time response of either a continuous time system or a sampled data system. The system configuration and parameters can be easily changed, allowing the INCA user to design compensation networks and perform sensitivity analysis in a very convenient manner. A journal file capability is included. This stores an entire sequence of commands, generated during an INCA session into a file which can be accessed later. Also included in INCA are a context-sensitive help library, a screen editor, and plot windows. INCA is robust to VAX-specific overflow problems. The transfer function is the basic unit of INCA. Transfer functions are automatically saved and are available to the INCA user at any time. A powerful, user friendly transfer function manipulation and editing capability is built into the INCA program. The user can do all transfer function manipulations and plotting without leaving INCA, although provisions are made to input transfer functions from data files. By using a small set of commands, the user may compute and edit transfer functions, and then examine these functions by using the ROOT_LOCUS, FREQUENCY_RESPONSE, and TIME_RESPONSE capabilities. Basic input data, including gains, are handled as single-input single-output transfer functions. These functions can be developed using the function editor or by using FORTRAN- like arithmetic expressions. In addition to the arithmetic functions, special functions are available to 1) compute step, ramp, and sinusoid functions, 2) compute closed loop transfer functions, 3) convert from S plane to Z plane with optional advanced Z transform, and 4) convert from Z

  5. Microscopic Rocks and Expansive Empires: Investigating Inca Ceramics from Cuzco, Peru

    Full Text Available High quality polychrome ceramics are an iconic aspect of Inca material culture. This ‘Cuzco Inca’ pottery appears suddenly in the archaeological record: but it draws upon technological and stylistic aspects of earlier local pottery and we discuss the specifics of how these pre-Inca traits were combined to form the distinctive new state ceramics. Using ceramic petrography, the dominant fabric of Cuzco Inca pottery is compared with those of two pre-Inca wares, Killke and Lucre. Andesite temper, identified in the Lucre and Cuzco Inca fabrics, is compared with samples of andesite from local geological outcrops. This suggests that Lucre pottery was made using similar materials to Cuzco Inca and was a technological precursor. Because these materials and technological knowledge would only have become available to the Inca after their conquest of the Lucre cultural area, this ceramic evidence has important implications for our understanding of Imperial expansion and state intervention in craft-production.

    Full Text Available Papua is rich with cultural heritages: hundreds of vernacular languages, tribes, folklores and other unique traditions. Unfortunately, these heritages are not recognized by the young generation anymore. Modernization, technology, and new comers are assumed as the background. As the capital of the province, Jayapura is the most influenced place for the changes. As an attempt to re-introduce and preserve the ancestor’s cultural heritages, cultural infusion in learning English (as one type of learning is regarded important. From seven tribes living in Jayapura, as the first step, Sentani is chosen as the priority. This paper discusses English learning materials by infusing Sentani culture. Folktales are chosen as learning materials for Elementary School students, malo[1] for Junior High School students, the procedure to make kayi/ifa[2] for Senior High Schoo students.  This infusion hopes that young generation is able to learn English as well as to acknowledge one of the cultural heritages of Papua. They can be strongly rooted in their culture and respect others’ culture. DOI: https://doi.org/10.24071/llt.2017.200105

    2015-03-01

    Suicidal attempts are steadily increasing in societies with rapid urbanisation and dramatic social changes in places like Istanbul. Stress related to internal migration may increase suicidal behaviour. We investigated the impact of internal migration and culture on suicide attempts among youth in Istanbul. We retrospectively analysed the records of 210 children and adolescents, aged 6-18 years, who presented at the Emergency Outpatient Clinic of the Department of Pediatrics at Cerrahpaşa Medical School in Istanbul because of suicide attempts between January 2008 and December 2010. The majority of patients (78.95%, N = 165) had a background of internal migration, mostly (65%, N = 136) originating from regions with large cultural differences compared with that of Istanbul. Noticeably, more migrants than non-migrants (18.8% vs. 6.8%) and more patients originating from regions with large cultural differences chose high-risk methods for suicide attempts (20.7% vs. 8.1%). Internal migration can be considered a serious risk factor for suicidal behaviour. Furthermore, the degree of cultural differences between the area of origin and the new environment can be of vital importance. Healthcare measures should, therefore, focus on internal migration as a risk factor for youth suicidal behaviour and provide assistance for appropriate resettlement and integration in countries with increased mobility.

    1989-01-01

    The INteractive Controls Analysis (INCA) program was developed at NASA's Goddard Space Flight Center to provide a user friendly, efficient environment for the design and analysis of control systems, specifically spacecraft control systems. Since its inception, INCA has found extensive use in the design, development, and analysis of control systems for spacecraft, instruments, robotics, and pointing systems. The (INCA) program was initially developed as a comprehensive classical design analysis tool for small and large order control systems. The latest version of INCA, expected to be released in February of 1990, was expanded to include the capability to perform multivariable controls analysis and design.

    The Inca Empire is claimed to have driven massive population movements in western South America, and to have spread Quechua, the most widely-spoken language family of the indigenous Americas. A test-case is the Chachapoyas region of northern Peru, reported as a focal point of Inca population displacements. Chachapoyas also spans the environmental, cultural and demographic divides between Amazonia and the Andes, and stands along the lowest-altitude corridor from the rainforest to the Pacific coast. Following a sampling strategy informed by linguistic data, we collected 119 samples, analysed for full mtDNA genomes and Y-chromosome STRs. We report a high indigenous component, which stands apart from the network of intense genetic exchange in the core central zone of Andean civilization, and is also distinct from neighbouring populations. This unique genetic profile challenges the routine assumption of large-scale population relocations by the Incas. Furthermore, speakers of Chachapoyas Quechua are found to share no particular genetic similarity or gene-flow with Quechua speakers elsewhere, suggesting that here the language spread primarily by cultural diffusion, not migration. Our results demonstrate how population genetics, when fully guided by the archaeological, historical and linguistic records, can inform multiple disciplines within anthropology.

    In a breeding group of Inca terns (Larosterna inca), 14 birds died without antemortem signs of illness. Other than a poor body condition and a bloody cloaca, no symptoms were observed. Gross necropsy revealed severe segmental hemorrhagic enteritis with intralesional trematodes in most birds. Histopathologic examination revealed infiltration of lymphocytes, plasma cells, and granulocytes in the lamina propria of the duodenum and cross-sections of trematodes in the lumen. The parasites were identified as Ichthyocotylurus erraticus, a trematode of fish-eating birds. The cause of the infestation most likely was the feeding of unfrozen fresh fish. We describe the first case of a lethal I. erraticus infestation in Inca terns.

    Full text: An archaeological site with several funerary houses built in the cliffs of the Laguna de los Condores by the Chachapoya people was discovered in 1997 in the cloud forest at a sea level of 2500 m in the Amazonas/San Martin area in Peru. The Chachapoya people and their culture is not fully understood until now and some myths entwine around the origin of that South American ancient civilisation. The Chachapoya are described as people of warriors, which were finally subdued by the Incas. A typical characteristic of their culture is the special burial of their dead in funeral bundles containing the remains of the bodies. At the Laguna de los Condores more that 200 mummies have been found and transferred to Leymebamba. During the rescue work of the mummies, which were in danger to be destroyed by looters, it turned out that two different burial patterns could be detected. It is assumed, that after conquering of the Chachapoyas, the Inca people took over also the burial cliff houses and used it for their own burials. The Incas themselves were subdued by the Spanish Conquistadors in 1532 AD. In order to shed light on the transition from the Chachapoya to the Inka dominance, which is connected with the history of the Laguna de los Condores funeral site, a multidisciplinary project between archaeologists, anthropologists and physicists has been started. VERA contributes to this project with several radiocarbon dates of archaeological objects and of the mummies from this Chachapoya/Inca site. (author)

    , collection and distribution of goods, regulation and censuses of the population, as well as population transfers and families formation related with a productive territory. The imperial interests flowed fast and silently over the network of roads, the main imperial structure. The Inca road infrastructure configured the conquered territory itself. Reading the territory implies a broad view of the historical, ecological and social context, as well as their potential and versatility to inhabit, linked to obtain profits without incurring in their deterioration, considering the density allowed by the medium in a given system. A sustainable eco-cultural tourism, of small scale, able to support the enormous human, geographical and archaeological potential that the place owns, could be managed by the local community itself, associated with its customs and traditional practices. This is consistent with the need to implement programs for heritage recognition and conservation. A minority of invited participants could be integrated in the experiential understanding of the territory, rather than just obtaining the benefit of an exotic landscape at an exotic location.

    Full Text Available The Inca Empire - the greatest pre-Columbian empire on the American continent - extended from Ecuador to central Chile for more than five thousand miles. Its capital was Cuzco established in the high Peruvian Andes. This highly advanced civilization developed a counting system used to run the empire - in particular, to build the 14,000 mile road structure and monumental architecture. Some of the algorithms believed to be used by the Inca to do computations using a yupana, an ancient calculating device, will be presented, as well as classroom activities for the course “Mathematics in Non-European Cultures” for non Mathematics and Science majors offered at Millersville University of Pennsylvania.

    The royal estates lying between Cusco and Machu Picchu illustrate the remarkable variety by which the sun was honored and worshipped in the Inca Empire. The terraced basins of Moray combine the sun at both solstices and, perhaps, the zenith sun, with flowing water and offerings to Pachamama. The complex astronomy at Urubamba involves the palace of Quespiwanka, horizon pillars, solstices, and mountain worship. Ollantaytambo contains horizontal shadow-casting gnomons with a major water shrine.

    2015-02-01

    Full Text Available At present, digital documentation recorded in the form of raster or vector files is the obligatory way of inventorying historical objects. The orthoimage is a cartometric form of photographic presentation of information in the two-dimensional reference system. The paper will discuss the issue of automation of the orthoimage generation basing on the TLS data and digital images. At present attempts are made to apply modern technologies not only for the needs of surveys, but also during the data processing. This paper will present attempts aiming at utilisation of appropriate algorithms and the author’s application for automatic generation of the projection plane, for the needs of acquisition of intensity orthoimages from the TLS data. Such planes are defined manually in the majority of popular TLS data processing applications. A separate issue related to the RGB image generation is the orientation of digital images in relation to scans. It is important, in particular in such cases when scans and photographs are not taken simultaneously. This paper will present experiments concerning the utilisation of the SIFT algorithm for automatic matching of intensity orthoimages of the intensity and digital (RGB photographs. Satisfactory results of the process of automation, as well as in relation to the quality of resulting orthoimages have been obtained.

    Traeen, B

    1992-01-01

    This study describes to what extent Norwegian adolescents were aware of a campaign to combat the spread of AIDS, and their participation in the various components. The material comprised a nationwide representative sample of 3000 adolescents aged 17 through 19 years. Data were collected by means of self-administered, anonymous questionnaires. The response rate was 62.8%. The intention of the campaign was to mobilize the youth culture in the fight against AIDS with a view to internalizing existing knowledge about HIV and AIDS in the hope of improving consistency between knowledge and sexual behavior. The campaign included five elements connected to the use of media and activities in the adolescents' social environment. The campaign slogan--Talk about sex, about being in love and about love--was referred to AIDS only indirectly. The medium used to communicate the message was rock music. Over one quarter of the adolescents reported a general awareness of the campaign. Awareness of the different elements varied between 2.4% and 24.0%. Use of condoms was apparently no higher among adolescents who were generally aware of the campaign than among adolescents with no knowledge of it. The adolescents had not grasped any specific message from the campaign. The campaign would probably have been more successful if the message had been more direct and more specific to the context.

    Full Text Available In the present investigation, aimed at obtaining beet haploids from anthers, the effect of mineral media, potato and sugar beet extract and p-fluorophenylalanine (PFP in combination with growth substances was tested. Nutrient-starved plants as anther-donors, anther-starvation, cold treatment and photoperiod were also analysed. On all mineral media the anthers produced callus and roots; however, the percentage depended on the combination of growth substances used. The best medium for differentiation was that of Linsmaier and Skoog with 25 µM zeatin or 6-(3-methyl-2-butenylaminopurine with 5 µM naphthalene-l-acetic acid (25.5%. The addition of PFP caused an increase in the percentage of anther differentiation (41.6%. Besides callus and roots on one of the anthers (in ca. 140000 tested, vegetative buds were formed from which numerous plants were obtained (2n. Plant and anther nutrient starvation did not improve the anther response to differentiation, nor did it induce haploid development, similarly as cold treatment of inflorescences or isolated anthers. The anthers of wild species showed lower ability to differentiate than those of sugar or fodder beets. Cytological analyses showed formation of multicellular structures until ca. the 12-th day of anther culture; afterwards, they degenerated.

  13. Pre-Inca Astronomy in Peru

    Science.gov (United States)

    McKim Malville, J.

    Huacas (shrines) and ushnus (ceremonial platforms) are ever-present elements of millennia-old Andean cosmology extending backward to 3100 BCE. Major themes of Pan-Andean cosmology include sacred mountains, the power of water, the solstice sun, as well as shamanic-like movement across the three worlds of the cosmos. Common features of many pre-Inca sites are monumental platforms and sunken circular plazas, and stairways with axes established by bi-lateral symmetries oriented along solstice lines. This style of ritual architecture first appeared in Chupacigarro/Caral, other sites in the Norte Chico area, and Sechin Bajo in the Casma Valley. Ceremonial plazas provided opportunities for public viewing of ritual ceremonies on the tops of platforms, which may have been understood as sacred mountains. Mounds and temples of the Casma Valley, such as Sechin Alto, Sechin Bajo, and Chankillo, developed an explicit astronomy associated with June and December solstices. The ritualistic use of water, which is typically associated with visual astronomy at Inca sites, appeared at Chavin de Huantar and later in Tiwanaku.

    To investigate the correlation between the incA I47T mutation in Chlamydia trachomatis and the nonfusogenic phenotype, the incA genes of 25 isolates were sequenced. Four major sequence types were identified. Seven isolates (28%) had the I47T mutation. Isolates representing the four sequence types expressed IncA in the membrane of one large single inclusion. In conclusion, the incA I47T mutation is not associated with the nonfusogenic phenotype.

En frecuencia que varían extensamente entre grupos étnicos diferentes hay más predominio entre mujeres. En el presente estudio reportamos el caso de un verdadero hueso cuadrangular interparietal o hueso inca en el cráneo humano adulto. Los huesos de wormian interparietal o los huesos epactal se diferencian de los huesos suturales sobre la base de su posición. Los huesos wormianos interparietales están localizados dentro de la región interparietal, mientras los huesos suturales son formados a partir de centros de osificación adicionales que pueden ocurrir en o cerca de las suturas. La osificación inadecuada de la región interparietal lleva a la formación de los huesos wormianos. Ellos también pueden estar relacionados con factores genéticos. El hueso interparietal es formado por la separación del segmento intermedio del plato lateral por la sutura occipital transversa, por lo tanto este hueso es formado por las placas intermedias y laterales que pueden ser únicas o múltiples. La localización de tales huesos está, sobre todo, en la parte central superior de la región interparietal. La ocurrencia de la variable del inca es rara es seres humanos.

    2005-01-01

    Purpose: The purpose of this paper was to determine the imaging findings in three 500-year-old Inca mummies and how modern radiology can be used in other sciences such as archaeology. Material and Method: Three naturally mummified children were studied using conventional radiography, dental radiography, CT and puncture biopsies. Working sessions were limited to 20 minutes to prevent thawing of the corpses and radiological techniques were adjusted to their particular anatomic position. Results: CT images showed shrinkaged internal organs due to dehydration. The fatty tissue of the bodies was visibly white because of the transformation of it into adipocere, favoring white matter/gray matter differentiation at the central nervous system. The lungs were expanded in the three corpses and right lung and maxillary sinus pathologies were determined in the older girl. Chronological ages of the three children at the time of their deaths were established. DNA studies determined no family links among them. The spleen was not seen in any case. Conclusions: Modern radiology is an excellent tool in archaeological research. Nutritional state, ages and pathologies of the three mummies were evaluated. (author) [es

  20. INCAS: an analytical model to describe displacement cascades

    2004-01-01

    REVE (REactor for Virtual Experiments) is an international project aimed at developing tools to simulate neutron irradiation effects in Light Water Reactor materials (Fe, Ni or Zr-based alloys). One of the important steps of the project is to characterise the displacement cascades induced by neutrons. Accordingly, the Department of Material Studies of Electricite de France developed an analytical model based on the binary collision approximation. This model, called INCAS (INtegration of CAScades), was devised to be applied on pure elements; however, it can also be used on diluted alloys (reactor pressure vessel steels, etc.) or alloys composed of atoms with close atomic numbers (stainless steels, etc.). INCAS describes displacement cascades by taking into account the nuclear collisions and electronic interactions undergone by the moving atoms. In particular, it enables to determine the mean number of sub-cascades induced by a PKA (depending on its energy) as well as the mean energy dissipated in each of them. The experimental validation of INCAS requires a large effort and could not be carried out in the framework of the study. However, it was verified that INCAS results are in conformity with those obtained from other approaches. As a first application, INCAS was applied to determine the sub-cascade spectrum induced in iron by the neutron spectrum corresponding to the central channel of the High Flux Irradiation Reactor of Oak Ridge National Laboratory

    Paleoparasitological studies have demonstrated that changes in environment or culture are reflected in the patterns of parasitic infection diseases in populations worldwide. The advent of agriculture and animal domestication, with its accompanying reduction in human mobility and expanding population involves changes in or emergence of, parasites, the so-called first epidemiological transition. Cultural processes related to territory occupation contribute to both loss and acquisition of parasites. The archaeological site Lluta 57 in the Lluta Valley, Chile, provides a chronology of the transition from the pre-Inca or Late Intermediate Period (LIP), through the Late or Inca Period (LP), to the Hispanic Contact Period (HCP), providing the possibility of evaluating this epidemiological transition. The aim of this study was to conduct a paleoparasitological investigation of to gain insight into the dynamics of parasitism in Lluta people throughout the Inca expansion. Fourteen human coprolites from the three periods were rehydrated, submitted to spontaneous sedimentation, and examined by light microscopy for the presence of intestinal parasite eggs, pollen grains, and micro-remains. Eggs of four parasites: Enterobius vermicularis, Trichostrongylus sp., Trichuris sp., and Eimeria macusaniensis were recovered. Frequency, diversity, and number of parasite eggs per sample increased over the studied time period. Trichostrongylus sp. and E. macusaniensis were recorded in the region for the first time. Enterobius vermicularis eggs, absent in the LIP, were present as a hyper-infection in LP. The presence of E. macusaniensis is likely related to exploitation of llamas, which were used for food and transport and as sacrificial offerings. The paleobotanical analysis revealed ten families of pollen grains, as well as phytoliths and floral remains. In contrast to parasitological results, a diachronic pattern was not detected.

    2007-01-01

    Full Text Available Existen varios elementos ideológicos en la narración histórica del Inca Garcilaso de la Vega y una concepción de progreso de la historia que se opone a la más antigua de Hesíodo y de la Iglesia. En sus Comentarios Reales de los Incas procura una reivindicación de su pueblo original, en un contexto español; para ser aceptado, se propone no reescribir directamente la historia oficial, pero trastoca los significados de aquellos “hechos” narrados con anterioridad por los españoles en su Perú natal. Al mismo tiempo, realiza un mestizaje cosmológico que servirá como herramienta para confirmar su concepción de la historia y reivindicar, al mismo tiempo, sus orígenes étnicos y culturales. Pero, en gran medida, su perspectiva religiosa e intelectual ya pertenece a España. El Inca Garcilaso de la Vega no reconoce el panteísmo de los preincaicos y lo rechaza desde una perspectiva cristiana que separa al hombre de la naturaleza, lo que demuestra su concepción europea de la divinidad. Desprecia las culturas preincaicas porque adoraban lo inferior a ellos, mientras que los Incas –como los cristianos– adoraban lo superior y la unidad: el Sol. Más aún, Garcilaso de la Vega identifica, sin nombrarlo, al Sol con Dios y a Pachacámac con el Espíritu Santo. Jesu Christo será la culminación del progreso hacia la perfección de la Trinidad. La consecuencia es una concepción progresista de la historia que incluye a los incas y todos los pueblos (imperfectos que los precedieron. Pasa por encima del rito, del dogma y de las formas para encontrar en el pueblo inca un destino común a la civilización cristiana. Con ello también revela un componente humanista de una historia que se desarrolla con un objetivo universal y mestizo. No por casualidad, se nombra “Inca” con un apellido español, de la Vega, y lucha por conciliar ambas tradiciones: es un proyecto histórico, una voluntad de síntesis y una reivindicación personal.

  9. 'Inca City' is Part of a Circular Feature

    2002-01-01

    MGS MOC Release No. MOC2-319, 8 August 2002 [figure removed for brevity, see original site] 'Inca City' is the informal name given by Mariner 9 scientists in 1972 to a set of intersecting, rectilinear ridges that are located among the layered materials of the south polar region of Mars. Their origin has never been understood; most investigators thought they might be sand dunes, either modern dunes or, more likely, dunes that were buried, hardened, then exhumed. Others considered them to be dikes formed by injection of molten rock (magma) or soft sediment into subsurface cracks that subsequently hardened and then were exposed at the surface by wind erosion. The Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) has provided new information about the 'Inca City' ridges, though the camera's images still do not solve the mystery. The new information comes in the form of a MOC red wide angle context frame taken in mid-southern spring, shown above left and above right. The original Mariner 9 view of the ridges is seen at the center. The MOC image shows that the 'Inca City' ridges, located at 82oS, 67oW, are part of a larger circular structure that is about 86 km (53 mi) across. It is possible that this pattern reflects an origin related to an ancient, eroded meteor impact crater that was filled-in, buried, then partially exhumed. In this case, the ridges might be the remains of filled-in fractures in the bedrock into which the crater formed, or filled-in cracks within the material that filled the crater. Or both explanations could be wrong. While the new MOC image shows that 'Inca City' has a larger context as part of a circular form, it does not reveal the exact origin of these striking and unusual martian landforms.

    Inca bones are accessory bones found in neurocranium of human skulls. Occurrence of Inca bones is rare as compared to other inter sutural bones such as wormian bones. These Inca ossicles are regarded as variants of the normal. The reporting of such occurrences is inadequate from Central India. To find the incidence of Inca variants in Central India. In the present study, 380 dried adult human skulls were examined. All specimen samples were procured from various Medical colleges of Central India. They were analyzed for gross incidence, sexual dimorphism and number of fragments of Inca bones. Gross incidence of Inca bones was found to be 1.315 %. Incidence rate was higher in male skulls than female skulls (male: 1.428%; female: 1.176%). The Inca bones frequently occurred signally. Out of the five observed Inca ossicles, two were fragmented. This data gives idea regarding gross incidence, sexual dimorphism and number of fragments of Inca bones in neurocranium of human skulls from Central India. The knowledge of this variable is useful for neurosurgeons, anthropologists and radiologists.

    Full Text Available The Inca Empire exhibited labor exploitation and the rational extraction of resources from peripheral polities by a core polity. These characteristics fit the general definition of a world empire, although core/periphery relations were diverse. The nature of core/periphery relations depended on several attributes of the conquered polity including population size, political power, natural resources, and distance from the Inca core at Cuzco. A dynamic picture of core/periphery relations emerges as the outcome of Inca demands for labor and raw materials, and peripheral peoples' desire for control over their autonomy while seeking benefits from the Inca state.

    Abstract: The development of a dictionary culture consists of three main phases: (a the information phase, (b the learning phase and (c the consolidation phase. The first step towards a new dictionary culture is to inform mother-tongue speakers of available dictionaries and their benefits for individual speakers. This information should mainly be distributed through dictionary awareness campaigns conducted in the relevant African languages and by influential mother-tongue speakers. The main difficulty of the learning phase consists in the teaching of different groups, for example lexicographers, teachers and students, as well as adults who want to consult a dictionary effectively. Although a basic knowledge of lexicography is useful for teachers, a natural association with dictionaries as well as an intimate knowledge of dictionaries is more important. An intimate knowledge of dictionaries includes, among others: the different dictionary types, the contents of dictionaries and the know-how to find the sought-for word. The last phase is the consolidation phase in which the association with dictionaries will change from an uncommon to a normal activity.

    Luo, Ting; Xu, Yanhua; Hoffman, Trevor L; Zhang, Tailin; Schilling, Thomas; Sargent, Thomas D

    2007-04-01

    Inca (induced in neural crest by AP2) is a novel protein discovered in a microarray screen for genes that are upregulated in Xenopus embryos by the transcriptional activator protein Tfap2a. It has no significant similarity to any known protein, but is conserved among vertebrates. In Xenopus, zebrafish and mouse embryos, Inca is expressed predominantly in the premigratory and migrating neural crest (NC). Knockdown experiments in frog and fish using antisense morpholinos reveal essential functions for Inca in a subset of NC cells that form craniofacial cartilage. Cells lacking Inca migrate successfully but fail to condense into skeletal primordia. Overexpression of Inca disrupts cortical actin and prevents formation of actin "purse strings", which are required for wound healing in Xenopus embryos. We show that Inca physically interacts with p21-activated kinase 5 (PAK5), a known regulator of the actin cytoskeleton that is co-expressed with Inca in embryonic ectoderm, including in the NC. These results suggest that Inca and PAK5 cooperate in restructuring cytoskeletal organization and in the regulation of cell adhesion in the early embryo and in NC cells during craniofacial development.

    2016-11-01

    Full Text Available This essay posits certain political-philosophical perspectives on the Inca Garcilaso de la Vega’s Primera parte de los Comentarios reales de los Incas (1609. To this purpose we will develop two hermeneutical movements. The first refers to a theoretical and methodological questioning related to the notion of Indian as a discursive construction during colonial times in the Andes area. The second deploys a critical exercise grounded on the interaction between the notions of Indian, Inca, and Mestizo, which is focused on how they build alternative subjectivities. Both movements consolidate an interpretation about the Inca Garcilaso’s political-philosophical reflections, remarking his proposals of a bifurcated modern civilizational project in the New World.

    The high prevalence of C. trachomatis worldwide has underscored the importance of identifying specific immunogenic antigens in facilitating diagnosis as well as vaccine development. The aim of this study is to evaluate IncA antibody and antigen production in natural human infections. Our temporal expression study showed that IncA transcription and protein expression could be detected as early as 4 hours after the start of infection. Antibody responses could be detected in urine and genital swab samples from C. trachomatis-positive patients. It is especially interesting to note that the IncA antigen could be detected in urine. In conclusion, we have identified IncA as an important antigen in human. The potential applicability of the IncA antibody or antigen in the diagnosis as well as to vaccine development for C. trachomatis is also discussed.

    2011-11-01

    This article addresses the bioarchaeological evidence for Inca warfare through an analysis of 454 adult skeletons from 11 sites in the Inca capital region of Cuzco, Peru. These 11 sites span almost 1000 years (AD 600-1532), which allows for a comparison of the evidence for warfare before the Inca came to power (Middle Horizon AD 600-1000), during the time of Inca ascendency in the Late Intermediate Period (AD 1000-1400), and after the Inca came to power and expanded throughout the Cuzco region and beyond (Inca Imperial Period, AD 1400-1532). The results indicate that 100 of 454 adults (22.0%) showed evidence of cranial trauma. Of these, 23 individuals had major cranial injuries suggestive of warfare, consisting of large, complete, and/or perimortem fractures. There was scant evidence for major injuries during the Middle Horizon (2.8%, 1/36) and Late Intermediate Period (2.5%, 5/199), suggesting that warfare was not prevalent in the Cuzco region before and during the Inca rise to power. Only in the Inca Imperial Period was there a significant rise in major injuries suggestive of warfare (7.8%, 17/219). Despite the significant increase in Inca times, the evidence for major cranial injuries was only sporadically distributed at Cuzco periphery sites and was entirely absent at Cuzco core sites. These findings suggest that while the Inca used warfare as a mechanism for expansion in the Cuzco region, it was only one part of a complex expansion strategy that included economic, political, and ideological means to gain and maintain control.

    1990-01-01

    Structural finite element models are often too large to be used in the design and analysis of control systems. Model reduction techniques must be applied to reduce the structural model to manageable size. In the past, engineers either performed the model order reduction by hand or used distinct computer programs to retrieve the data, to perform the significance analysis and to reduce the order of the model. To expedite this process, the latest version of INCA has been expanded to include an interactive graphical structural mode significance and model order reduction capability.

    Full Text Available Functional differences between healthy progenitor and cancer initiating cells may provide unique opportunities for targeted therapy approaches. Hematopoietic stem cells are tightly controlled by a network of CDK inhibitors that govern proliferation and prevent stem cell exhaustion. Loss of Inca1 led to an increased number of short-term hematopoietic stem cells in older mice, but Inca1 seems largely dispensable for normal hematopoiesis. On the other hand, Inca1-deficiency enhanced cell cycling upon cytotoxic stress and accelerated bone marrow exhaustion. Moreover, AML1-ETO9a-induced proliferation was not sustained in Inca1-deficient cells in vivo. As a consequence, leukemia induction and leukemia maintenance were severely impaired in Inca1-/- bone marrow cells. The re-initiation of leukemia was also significantly inhibited in absence of Inca1-/- in MLL-AF9- and c-myc/BCL2-positive leukemia mouse models. These findings indicate distinct functional properties of Inca1 in normal hematopoietic cells compared to leukemia initiating cells. Such functional differences might be used to design specific therapy approaches in leukemia.

    2010-07-01

    Full Text Available This essay analyzes the indigenous rebellions and its evolution in Perú during the XVIII century as well as the functions and impact that nostalgia and utopia had against the mastery of Spanish, keeping in mind that both, nostalgia and utopia, were used like instruments against this movement. The uprising increases due to the abuse of power and the constant inequalities of imperial economy in and around the viceroyalty based on specific unions between social actors. By the year 1780, they conformed a group called broad Inca nationalist movement whose clear expression was showed in the insurrection promoted by Tupac Amaru. We are going to present the possible interpretations to study the evolution of this movement through this project which is related to the history context OLLANTAY. Simultaneously we are going to take advantage of it in order to analyze other texts and arts.

    2017-10-01

    Full Text Available Purpose – This study aims to present the mechanisms of control and accountability used in the Inca society. Design/methodology/approach – For this purpose, a bibliographical and documental analysis regarding the use of khipus in this civilization was carried out, applying a qualitative approach. Findings – The results of the study indicate that the Inca khipu was the main instrument of tax registration and management adopted by the Inca empire. The Khipucamayocs were responsible for the production of the Khipu, asserting that the information generated and consolidated in the imperial khipu was correct, considering that these professionals paid with their lives in case of errors. Originality/value – The main contributions to accounting are related to the understanding of the origin of the development of tax control and accountability tools created in the Inca Empire, before the Spanish invasions, that contributed significantly to the development of the first American societies

    Full Text Available Os mitos relativos ao Inca recolhidos na Amazônia entre vários grupos de língua pano têm sido entendidos como memórias de um passado remoto regido por uma aristocracia quechua ou como expressão de uma estrutura identitária ou cosmológica em que o Inca significaria o Branco ou uma alteridade celestial. Tais interpretações, apesar de seu valor heurístico, limitam nossa compreensão dos aspectos estruturais e históricos do Inca Pano. Propõe-se aqui entender o Inca também como um símbolo eficiente, vinculado a modelos sociológicos e/ou artísticos de alto valor distintivo: povos como os Shipibo-Conibo e os Kaxinawá cristalizam em torno dessa figura uma tradição que os destaca do conjunto dos grupos nawa vizinhos.The Amazonian myths collected among certain Panoan-speaking peoples which make reference to the Inca figure have generally been subject to one of two interpretations. They are either seen to recall a remote past in which these peoples may have been ruled by Quechua aristocrats or they are seen to be structural aspects of identity or cosmology, in which the Inca would be representative of the White man or of some celestial alterity. These interpretations, in spite of their heuristic value, serve to limit our understanding of structural and historical aspects of the Pano Inca. This article proposes that we also try to understand the Pano Inca as an effective symbol, related to social and/or artistic models with their own distinctive values: people such as the Shipibo-Conibo and the Kaxinawa have shaped around this figure a tradition which sets them apart from the neighbouring Nawa groups.

    In this study, an Inca bundle was examined using computed tomography (CT). The primary aim was to determine the preservation status of bony and soft tissues, the sex, the age at the time of death, possible indicators for disease or even the cause of death, as well as the kind of mummification. A secondary aim was to obtain a brief overview of the wrapping in order to gain additional information on the cultural background. The bundle belongs to the Museum of Cultures in Basel, Switzerland, and was bought in Munich, Germany, in 1921. Radiocarbon dating of the superficial textile yielded a calibrated age between 1480 and 1650 AD. The mummy was investigated using multi-slice CT with slice thickness of 0.75 mm and 110 kilovolt. For standardized assessment of soft tissue preservation, a recently developed checklist was applied. CT revealed the mummy of a seven to nine year old boy with superior preservation of bony and soft tissues allowing detailed assessment. Indicators of neurofibromatosis type 1 (paravertebral and cutaneous neurofibromas, a breast neurofibroma, sphenoid wing dysplasia), Chagas disease (dilatation of the esophagus, stomach, rectum, and large amounts of feces), and lung infection (pleural adherence, calcifications), probably due to tuberculosis, were found. Furthermore, signs of peri-mortem violence (transection of the chest and a defect in the abdominal wall) were detected. CT images revealed a carefully performed wrapping. CT examination of the Inca bundle proved to be an important non-destructive examination method. Standardized assessment, especially of the soft tissue structures, allowed for diagnoses of several diseases, indicating a multi-morbid child at the time of death. The careful wrapping pointed to a ceremonial burial. Within the cultural background, the signs of fatal violence were discussed as a possible result of war, murder, accident, or human sacrifice.

  15. Exploring pain in the Andes--learning from the Quichua (Inca) people experience.

    2015-05-01

    There is a mounting recognition that culture profoundly shapes human pain experience. The 28 million indigenous people of the Andes in South America, mainly the Quichua (Inca) people, share a distinctive culture. However, little is known about their pain experience and suffering. The aim of the present study was to explore how Quichua adults perceive, describe, and cope with the pain. An exploratory qualitative/descriptive study was conducted with a convenience sample of 40 Quichua adults, including 15 women and 25 men, in the Northern Highlands of Ecuador. Data were collected through structured interviews of approximately 3 h, using a Quichua questionnaire called "The Nature of Pain" [Nanay Jahua Tapuicuna]. The interviews covered the notions of causation of pain, vulnerability to pain, responses to pain, aggravating factors, frequent locations of pain, types of pain, duration, characteristics of pain, control of pain, pathways to care, and preventive measures of pain. Basic descriptive analyses were performed. The Quichuas' pain experience is complex and their strategies to cope with it are sophisticated. According to the Quichuas, emotions, life events, co-morbid conditions, and spirits, among others factors play an important role in the origin, diagnosis, and treatment of pain. They strongly embrace biomedicine and physicians as well as Quichua traditional medicine and traditional healers. Family members and neighbors are also valuable sources of health care and pain control. The pathway to pain care that the Quichua people prefer is inclusive and pluralistic. The knowledge of the Quichua ethnographic "emic" details of their belief system and coping strategies to control pain are clinically useful not only for the health professional working in the Andes, some Quichua cultural characteristics related to pain could be useful to the culturally competent health practitioner who is making efforts to provide high-quality medical care in rural and multicultural

    Full Text Available Ce témoignage de Cayo Inga est un document important qui retrace les succès des premières années de la pénétration espagnole au Pérou, de la côte de Tumbes à la ville de Cuzco. Sa valeur exceptionnelle tient à la qualité de l'informateur-membre du lignage inca et au fait qu'il ait été un témoin personnel des faits qu'il décrit. Par ce manuscrit, nous savons que Waskar Inga connut opportunément l'invasion étrangère à partir de la côte de Tumbes et que les Espagnols exigèrent une rançon au captif Atao Wallpa lui promettant de relâcher après. Nous sommes également renseignés sur le fameux pillage du temple de Pachacamac, sur la dramatique demande d'Atao Wallpa suppliant d'être exilé en Espagne et sur l'emprisonnement de Mango Inga Yupangui. Enfin, ce manuscrit éclaircit quelques faits quant aux sièges de la ville de Cuzco et de celle de Lima en 1536. El testimonio de Cayo Inga, es un documento excepcional para rehacer los sucesos de los primeros años de la penetración española en el Perú, de la costa tumbesina a la ciudad del Cuzco primero por la calidad del informante miembro del linaje Inca y segundo por su presencialidad en el lugar de los hechos. Este manuscrito, aclara que Waskar Inga conoció oportunamente la invasión de la costa tumbesina por los extranjeros y refiere que los españoles exigieron al cautivo Atao Wallpa un rescate, prometiéndole soltarlo después. Reseña a la vez el famoso saqueo del adoratorio de Pachacamac, el dramático pedido de Atao Wallpa para que lo exiliaran a España y el prendimiento de Mango Inga Yupangui, finalmente aporta datos sobre los asedios de la ciudad del Cuzco y de Lima en 1536. Cayo Inga's testimony is a document of exceptional value in the retracing of the events of the first years of the Spanish invasion and occupation of the country from Tumbes to Cuzco. It is remarkable for the quality of the source of information, since the reporter was both a member of the Inca

  18. The Location of Lake Titicaca's Coastal Area During the Tiwanaku and Inca Periods: Methodology and Strategies of Underwater Archaeology

    Science.gov (United States)

    Delaere, Christophe

    2017-12-01

    For more than 30 years, numerous research projects have revealed the dense and complex human settlement of the lacustrine basin of Lake Titicaca in Bolivia and Peru. Physical evidence of such establishments has been discovered in plains, valleys, and highlands connected to the lake. These remains confirm human occupation and development in this environment, particularly during the Tiwanaku (AD 500-1150) and Inca (AD 1400-1532) Periods. The research project discussed in this paper includes consideration of submerged areas through underwater archaeology. This investigation involves analysis of two areas that have evidence of ancient human occupation but are poorly documented: the coastal and lacustrine regions. Due to its dominance in the landscape, Lake Titicaca has always been a major feature in the life and identity of populations of this vicinity. These inhabitants have developed socio-economic and ritual behaviours directly associated with the lake that have left cultural and material prints that are the foci of the present study.

    2012-04-01

    The INCA-CE (Integrated Nowcasting through Comprehensive Analysis - Central Europe) project aims at implementing a transnational weather information system as well as applications for different socio-economic sectors to reduce risks of major economic damage and loss of life caused by severe weather. Civil protection and also stakeholders from economic sectors are in a growing need of accurate and reliable short-term weather forecasts. Within INCA-CE, a state-of-the art nowcasting system (INCA) is implemented at weather services throughout the European Union's CE (Central Europe) Programme Area, providing analyses and short term forecasts to the aforementioned end-users. In a coherent approach, the INCA (Integrated Nowcasting through Comprehensive Analysis) system will be adapted for implementation and use in a number of partner countries. Within transregional working groups, the gap between short-term weather information and its downstream activities in hydrological disaster management, civil protection and road management will be bridged and best practice management and measure plans will be produced. A web-based platform for outreach to related socio-economic sectors will initiate and foster a dialogue between weather services and further stakeholders like tourism or the insurance sector, flood authorities for disaster management, and the construction industry for cost-efficient scheduling and planning. Furthermore, the project will produce a compact guideline for policy makers on how to combine structural development aspects with these new features. In the present paper, an outline of the project implementation, a short overview about the INCA system and two case studies on precipitation nowcasts will be given. Moreover, directions for further developments both within the INCA system and the INCA-CE project will be pointed out.

    Full Text Available Little is still known about the microbiome resulting from the process of mummification of the human gut. In the present study, the gut microbiota, genes associated with metabolism, and putative resistome of Inca and Italian nobility mummies were characterized by using high-throughput sequencing. The Italian nobility mummies exhibited a higher bacterial diversity as compared to the Inca mummies when using 16S ribosomal (rRNA gene amplicon sequencing, but both groups showed bacterial and fungal taxa when using shotgun metagenomic sequencing that may resemble both the thanatomicrobiome and extant human gut microbiomes. Identification of sequences associated with plants, animals, and carbohydrate-active enzymes (CAZymes may provide further insights into the dietary habits of Inca and Italian nobility mummies. Putative antibiotic-resistance genes in the Inca and Italian nobility mummies support a human gut resistome prior to the antibiotic therapy era. The higher proportion of putative antibiotic-resistance genes in the Inca compared to Italian nobility mummies may support the hypotheses that a greater exposure to the environment may result in a greater acquisition of antibiotic-resistance genes. The present study adds knowledge of the microbiome resulting from the process of mummification of the human gut, insights of ancient dietary habits, and the preserved putative human gut resistome prior the antibiotic therapy era.

  2. Establishing homology between mitochondrial calcium uniporters, prokaryotic magnesium channels and chlamydial IncA proteins.

    Mitochondrial calcium uniporters (MCUs) (TC no. 1.A.77) are oligomeric channel proteins found in the mitochondrial inner membrane. MCUs have two well-conserved transmembrane segments (TMSs), connected by a linker, similar to bacterial MCU homologues. These proteins and chlamydial IncA proteins (of unknown function; TC no. 9.B.159) are homologous to prokaryotic Mg(2+) transporters, AtpI and AtpZ, based on comparison scores of up to 14.5 sds. A phylogenetic tree containing all of these proteins showed that the AtpZ proteins cluster coherently as a subset within the large and diverse AtpI cluster, which branches separately from the MCUs and IncAs, both of which cluster coherently. The MCUs and AtpZs share the same two TMS topology, but the AtpIs have four TMSs, and IncAs can have either two (most frequent) or four (less frequent) TMSs. Binary alignments, comparison scores and motif analyses showed that TMSs 1 and 2 align with TMSs 3 and 4 of the AtpIs, suggesting that the four TMS AtpI proteins arose via an intragenic duplication event. These findings establish an evolutionary link interconnecting eukaryotic and prokaryotic Ca(2+) and Mg(2+) transporters with chlamydial IncAs, and lead us to suggest that all members of the MCU superfamily, including IncAs, function as divalent cation channels. © 2014 The Authors.

Reuniendo un mosaico de datos aparentemente inconexos, este artículo revisa las versiones corrientes del descubrimiento del cerro e interroga un curioso silencio presente en las fuentes. Reconstruyendo una red previamente desconocida de incas y españoles, se propone que, más que el hallazgo providencial de un yanacona aislado (la versión recibida, Potosí se manifestó como continuación de la política de “obediencia” subyacente en la entrega de Porco, ahora dirigida por el rival del Inca Paullo: el Inca Manco refugiado en Vilcabamba.

    Full Text Available Prior to his rebellion against the Spanish Crown in 1544, Gonzalo Pizarro (Francisco’s younger brother accomplished the Conquest of Charcas (present-day northwestern Bolivia, survived the siege of Cuzco by Manco Inca and attempted the failed exploration of the mythical «Land of the Cinnamon Tree», located somewhere in the Amazonian basin, according to Garcilaso’s historical account. During this doomed expedition, Pizarro endured treason, lost companions and was defeated by the forces of an aggressive environment. However, he ma­naged to emerge as the legendary political and military leader that rebelled against the first Viceroy of Peru, Blasco Nuñez Vela in 1546. Nuñez Vela would be defeated in battlefield and later executed. Gonzalo Pizarro’s pretension of becoming king of Peru by virtue of a political alliance with the surviving Incas would be seen in Garcilaso’s account as a proof of Pizarro’s heroic stature, albeit a tragic one.

    Chlamydia psittaci produces a collection of proteins, termed IncA, IncB, and IncC, that are localized to the chlamydial inclusion membrane. In this report we demonstrate that IncA is also produced by Chlamydia trachomatis. C. trachomatis IncA is structurally similar to C. psittaci IncA and is also localized to the inclusion membrane. Immunoblot analysis demonstrated that sera from C. trachomatis-infected patients and from experimentally infected monkeys both recognized C. trachomatis IncA.

    2007-01-01

    In 1997 a new archaeological site was discovered in the Peruvian tropical rain forest. The site is located in an area which has been occupied by the Chachapoya, a pre-Incan people, from about 800AD on. The site comprises a large funerary place with several mausoleums built in the cliffs next to the Laguna de los Condores. More than 200 human mummies and funerary bone-bundles together with numerous grave artefacts have been found there. Although the site has been ascribed to the Chachapoya, the mummification method used is very similar to the one applied by the Inca. As part of an ongoing multidisciplinary project to explore the history of this site and of the Chachapoya people, twenty-seven (27) 14 C-AMS age determinations were performed. Samples, bones and textile wrappings as well as samples from a funerary bone bundle plus associated grave artefacts were dated. The 14 C data show that the site originates from the Chachapoya pre-Inca period and that in addition, it was used as a funerary place during the subsequent Inca occupation era. The radiocarbon results indicate that the Chachapoya may have changed their burial tradition due to the colonization by the Inca

    In 1985, a frozen mummy was found in Cerro Aconcagua (Argentina). Archaeological studies identified the mummy as a seven-year-old Inca sacrifice victim who lived >500 years ago, at the time of the expansion of the Inca Empire towards the southern cone. The sequence of its entire mitogenome was obtained. After querying a large worldwide database of mitogenomes (>28,000) we found that the Inca haplotype belonged to a branch of haplogroup C1b (C1bi) that has not yet been identified in modern Native Americans. The expansion of C1b into the Americas, as estimated using 203 C1b mitogenomes, dates to the initial Paleoindian settlements (~18.3 thousand years ago [kya]); however, its internal variation differs between Mesoamerica and South America. By querying large databases of control region haplotypes (>150,000), we found only a few C1bi members in Peru and Bolivia (e.g. Aymaras), including one haplotype retrieved from ancient DNA of an individual belonging to the Wari Empire (Peruvian Andes). Overall, the results suggest that the profile of the mummy represents a very rare sub-clade that arose 14.3 (5-23.6) kya and could have been more frequent in the past. A Peruvian Inca origin for present-day C1bi haplotypes would satisfy both the genetic and paleo-anthropological findings.

    Chlamydia is an intracellular bacterium that establishes residence within parasitophorous compartments (inclusions) inside host cells. Chlamydial inclusions are uncoupled from the endolysosomal pathway and undergo fusion with cellular organelles and with each other. To do so, Chlamydia expresses proteins on the surface of the inclusion using a Type III secretion system. These proteins, termed Incs, are located at the interface between host and pathogen and carry out the functions necessary for Chlamydia survival. Among these Incs, IncA plays a critical role in both protecting the inclusion from lysosomal fusion and inducing the homotypic fusion of inclusions. Within IncA are two regions homologous to eukaryotic SNARE (soluble N-ethylmaleimide-sensitive factor attachment receptor) domains referred to as SNARE-like domain 1 (SLD1) and SNARE-like domain 2 (SLD2). Using a multidisciplinary approach, we have discovered the functional core of IncA that retains the ability to both inhibit SNARE-mediated fusion and promote the homotypic fusion of Chlamydia inclusions. Circular dichroism and analytical ultracentrifugation experiments show that this core region is composed almost entirely of α-helices and assembles into stable homodimers in solution. Altogether, we propose that both IncA functions are encoded in a structured core domain that encompasses SLD1 and part of SLD2. PMID:25324548

    The aim of this investigation was to assess the Ku70/Ku80 complex as a potential target for antibody imaging of prostate cancer. We evaluated the in vivo and ex vivo tumor targeting and biodistribution of the (111)In-labeled human internalizing antibody, INCA-X ((111)In-DTPA-INCA-X antibody), in NMRI-nude mice bearing human PC-3, PC-3M-Lu2 or DU145 xenografts. DTPA-conjugated, non-labeled antibody was pre-administered at different time-points followed by a single intravenous injection of (111)In-DTPA-INCA-X. At 48, 72 and 96 h post-injection, tissues were harvested, and the antibody distribution was determined by measuring radioactivity. Preclinical SPECT/CT imaging of mice with and without the predose was performed at 48 hours post-injection of labeled DTPA-INCA-X. Biodistribution of the labeled antibody showed enriched activity in tumor, spleen and liver. Animals pre-administered with DTPA-INCA-X showed increased tumor uptake and blood content of (111)In-DTPA-INCA-X with reduced splenic and liver uptake. The in vitro and in vivo data presented show that the (111)In-labeled INCA-X antibody is internalized into prostate cancer cells and by pre-administering non-labeled DTPA-INCA-X, we were able to significantly reduce the off target binding and increase the (111)In-DTPA-INCA-X mAb uptake in PC-3, PC-3M-Lu2 and DU145 xenografts. The results are encouraging and identifying the Ku70/Ku80 antigen as a target is worth further investigation for functional imaging of prostate cancer.

    Chlamydia trachomatis is an obligate intracellular pathogen that is the etiological agent of a variety of human diseases, including blinding trachoma and sexually transmitted infections. Chlamydiae replicate within a membrane-bound compartment, termed an inclusion, which they extensively modify by the insertion of type III secreted proteins called Inc proteins. IncA is an inclusion membrane protein that encodes two coiled-coil domains that are homologous to eukaryotic SNARE (soluble N-ethylmaleimide-sensitive factor attachment receptor) motifs. Recent biochemical evidence suggests that a functional core, composed of SNARE-like domain 1 (SLD-1) and part of SNARE-like domain 2 (SLD-2), is required for the characteristic homotypic fusion of C. trachomatis inclusions in multiply infected cells. To verify the importance of IncA in homotypic fusion in Chlamydia, we generated an incA::bla mutant. Insertional inactivation of incA resulted in the formation of nonfusogenic inclusions, a phenotype that was completely rescued by complementation with full-length IncA. Rescue of homotypic inclusion fusion was dependent on the presence of the functional core consisting of SLD-1 and part of SLD-2. Collectively, these results confirm in vitro membrane fusion assays identifying functional domains of IncA and expand the genetic tools available for identification of chlamydia with a method for complementation of site-specific mutants. Chlamydia trachomatis replicates within a parasitophorous vacuole termed an inclusion. The chlamydial inclusions are nonfusogenic with vesicles in the endocytic pathway but, in multiply infected cells, fuse with each other to form a single large inclusion. This homotypic fusion is dependent upon the presence of a chlamydial inclusion membrane-localized protein, IncA. Specificity of membrane fusion in eukaryotic cells is regulated by SNARE (soluble N-ethylmaleimide sensitive factor attachment receptor) proteins on the cytosolic face of vesicles and target

    The Inca site at Curamba is located in the Province of Apurimac in the southern highlands of Peru where, according to some historians, several thousand furnaces used for ore smelting were found. For this work, four samples of burned soil were gathered from these furnaces and classified as Curamba1, Curamba2, Curamba3, and Curamba4, and studied using transmission Moessbauer spectroscopy (TMS) and X-ray diffractometry (XRD). The mineralogical composition of the samples was determined by XRD and the structural sites in the minerals occupied by iron cations were characterized by TMS. Moreover, an attempt was made to determine the maximum temperature reached in these furnaces using the refiring technique of the samples in an oxidizing environment and monitoring the structural modifications at the iron sites by changes in the Moessbauer hyperfine parameters. The TMS results of Curamba2 show that the maximum temperature reached in this furnace was about 900 deg. C, in agreement with the mineralogical composition found by XRD. In the case of Curamba1 and Curamba4 the maximum temperature estimated was about 400 deg. C.

  2. The inhibitor of growth protein 5 (ING5 depends on INCA1 as a co-factor for its antiproliferative effects.

    Directory of Open Access Journals (Sweden)

    Feng Zhang

    Full Text Available The proteins of the Inhibitor of Growth (ING family are involved in multiple cellular functions such as cell cycle regulation, apoptosis, and chromatin remodeling. For ING5, its actual role in growth suppression and the necessary partners are not known. In a yeast-two-hybrid approach with human bone marrow derived cDNA, we identified ING5 as well as several other proteins as interaction partners of Inhibitor of cyclin A1 (INCA1 that we previously characterized as a novel interaction partner of cyclin A1/CDK2. ING5 expression in leukemic AML blasts was severely reduced compared to normal bone marrow. In line, ING5 inhibited bone marrow colony formation upon retroviral transduction. However, Inca1(-/- bone marrow colony formation was not suppressed by ING5. In murine embryonic fibroblast (MEF cells from Inca1(+/+ and Inca1(-/- mice, overexpression of ING5 suppressed cell proliferation only in the presence of INCA1, while ING5 had no effect in Inca1(-/- MEFs. ING5 overexpression induced a delay in S-phase progression, which required INCA1. Finally, ING5 overexpression enhanced Fas-induced apoptosis in Inca1(+/+ MEFs, while Inca1(-/- MEFs were protected from Fas antibody-induced apoptosis. Taken together, these results indicate that ING5 is a growth suppressor with suppressed expression in AML whose functions depend on its interaction with INCA1.

  5. The Inca healer: empirical medical knowledge and magic in pre-Columbian Peru

    2015-08-01

    Full Text Available The role of medical practitioners among the Incas is addressed, based on archeological findings and especially the writings of the Spanish chroniclers. In Inca medicine a large role was reserved for religion and magic but at the same time an extensive knowledge of medicinal plants was available. As a consequence there were several types of healers who cured with a mixture of medicinal plants and religious-magic ceremonies. The hampicamayoc or ‘official in charge of medicines’ was the one who resembled somewhat the European physician of that time and was the most important type of healer. He relied largely but certainly not exclusively on the use of medicinal plants. There were also healers who cured mainly with religious-magic procedures. Surgery must have been important for the Inca healer but this is hardly reflected in the work of the Spanish chroniclers.La posición social de los profesionales de la medicina en la Cultura Inca se conoce gracias a los hallazgos arqueológicos y, sobre todo, gracias a los escritos de los cronistas españoles. En la medicina Inca, la religión y la magia ocupaban un papel destacado, aunque también era importante el conocimiento de las plantas medicinales. En consecuencia, existieron distintos tipos de curanderos que curaban con una mezcla más o menos mayor de plantas medicinales y ceremonias religiosas y mágicas. El hampicamayoc o «funcionario encargado de los medicamentos» sobresalía entre los curanderos y tenía cierto parecido con el médico europeo de la época. Su actuación se basaba sobre todo, aunque no exclusivamente, en el uso de plantas medicinales. Otros, en cambio, curaban básicamente con procedimientos mágicoreligiosos. La cirugía debió ser importante para el sanador Inca pero este hecho apenas se refleja en la obra de los cronistas españoles.

  6. Two coiled-coil domains of Chlamydia trachomatis IncA affect membrane fusion events during infection.

    Directory of Open Access Journals (Sweden)

    Erik Ronzone

    Full Text Available Chlamydia trachomatis replicates in a parasitophorous membrane-bound compartment called an inclusion. The inclusions corrupt host vesicle trafficking networks to avoid the degradative endolysosomal pathway but promote fusion with each other in order to sustain higher bacterial loads in a process known as homotypic fusion. The Chlamydia protein IncA (Inclusion protein A appears to play central roles in both these processes as it participates to homotypic fusion and inhibits endocytic SNARE-mediated membrane fusion. How IncA selectively inhibits or activates membrane fusion remains poorly understood. In this study, we analyzed the spatial and molecular determinants of IncA's fusogenic and inhibitory functions. Using a cell-free membrane fusion assay, we found that inhibition of SNARE-mediated fusion requires IncA to be on the same membrane as the endocytic SNARE proteins. IncA displays two coiled-coil domains showing high homology with SNARE proteins. Domain swap and deletion experiments revealed that although both these domains are capable of independently inhibiting SNARE-mediated fusion, these two coiled-coil domains cooperate in mediating IncA multimerization and homotypic membrane interaction. Our results support the hypothesis that Chlamydia employs SNARE-like virulence factors that positively and negatively affect membrane fusion and promote infection.

    Examination of three frozen bodies, a 13-y-old girl and a girl and boy aged 4 to 5 y, separately entombed near the Andean summit of Volcán Llullaillaco, Argentina, sheds new light on human sacrifice as a central part of the Imperial Inca capacocha rite, described by chroniclers writing after the Spanish conquest. The high-resolution diachronic data presented here, obtained directly from scalp hair, implies escalating coca and alcohol ingestion in the lead-up to death. These data, combined with archaeological and radiological evidence, deepen our understanding of the circumstances and context of final placement on the mountain top. We argue that the individuals were treated differently according to their age, status, and ritual role. Finally, we relate our findings to questions of consent, coercion, and/or compliance, and the controversial issues of ideological justification and strategies of social control and political legitimation pursued by the expansionist Inca state before European contact.

  11. Dynamic intensity-modulated non-coplanar arc radiotherapy (INCA) for head and neck cancer

    International Nuclear Information System (INIS)

    2006-01-01

    Background and purpose: To define the potential advantages of intensity-modulated radiotherapy (IMRT) applied using a non-coplanar dynamic arc technique for the treatment of head and neck cancer. Materials and methods: External beam radiotherapy (EBRT) was planned in ten patients with head and neck cancer using coplanar IMRT and non-coplanar arc techniques, termed intensity modulated non-coplanar arc EBRT (INCA). Planning target volumes (PTV1) of first order covered the gross tumor volume and surrounding clinical target volume treated with 68-70 Gy, whereas PTV2 covered the elective lymph nodes with 54-55 Gy using a simultaneous internal boost. Treatment plan comparison between IMRT and INCA was carried out using dose-volume histogram and 'equivalent uniform dose' (EUD). Results: INCA resulted in better dose coverage and homogeneity of the PTV1, PTV2, and reduced dose delivered to most of the organs at risk (OAR). For the parotid glands, a reduction of the mean dose of 2.9 (±2.0) Gy was observed (p 0.002), the mean dose to the larynx was reduced by 6.9 (±2.9) Gy (p 0.003), the oral mucosa by 2.4 (±1.1) Gy (p < 0.001), and the maximal dose to the spinal cord by 3.2 (±1.7) Gy (p = 0.004). The mean dose to the brain was increased by 3.0 (±1.4) Gy (p = 0.002) and the mean lung dose increased by 0.2 (±0.4) Gy (p = 0.87). The EUD suggested better avoidance of the OAR, except for the lung, and better coverage and dose uniformity were achieved with INCA compared to IMRT. Conclusion: Dose delivery accuracy with IMRT using a non-coplanar dynamic arc beam geometry potentially improves treatment of head and neck cancer

    On 16 December 2008, FDA issued a class warning for antiepileptic drugs and suicidal thoughts and behavior. The purpose of this study was to determine if the antiepileptic drug gabapentin increases risk of suicide attempt in patients to which it was prescribed for various indications. We conducted a pharmacoepidemiologic study in which suicide attempt rates were compared before and after gabapentin was prescribed. We used the PharMetrics medical claims database to study the relationship between gabapentin and suicide attempts in a cohort of 131,178 patients with a 1-year window of information before and after initial prescription. Patients had diagnoses of epilepsy, pain disorders, bipolar illness, major depressive disorder, schizophrenia, and other psychiatric disorders. Overall, there was no significant difference in suicide attempt rates before (3.48/1000 patient years--PY) versus after (3.45/1000 PY) gabapentin prescription. Pre-prescription suicide attempt rates were five times higher in psychiatric populations compared with non-psychiatric populations leading us to analyze the two groups separately. No drug effect was detected in the non-psychiatric populations. Significant reductions in suicide attempt rates were seen for bipolar disorder (47.85/1000 PY versus 31.46/1000 PY), major depressive disorder (17.30/1000 PY versus 12.66/1000 PY), and other psychiatric disorders (12.84/1000 PY versus 10.14/1000 PY). Person-time analysis revealed an overall significant reduction in suicide attempt rates (2.01/1000 PY on drug versus 2.30/1000 PY off drug). This study finds that gabapentin does not increase risk of suicide attempts in non-psychiatric populations and is associated with a reduction in suicide attempt risk in patients with psychiatric disorders.

    The rapid expansion of the Inca from the Cuzco area of highland Peru (ca. AD 1400-1532) produced the largest empire in the New World. Although this meteoric growth may in part be due to the adoption of innovative societal strategies, supported by a large labour force and a standing army, we argue that it would not have been possible without increased crop productivity, which was linked to more favourable climatic conditions. Here we present a multi-proxy, high-resolution 1200-year lake sediment record from Marcacocha, located 12 km north of Ollantaytambo, in the heartland of the Inca Empire. This record reveals a period of sustained aridity that began from AD 880, followed by increased warming from AD 1100 that lasted beyond the arrival of the Spanish in AD 1532. These increasingly warmer conditions would have allowed the Inca and their immediate predecessors the opportunity to exploit higher altitudes (post-AD 1150) by constructing agricultural terraces that employed glacial-fed irrigation, in combination with deliberate agroforestry techniques. There may be some important lessons to be learnt today from these strategies for sustainable rural development in the Andes in the light of future climate uncertainty.

    Full Text Available The rapid expansion of the Inca from the Cuzco area of highland Peru (ca. AD 1400–1532 produced the largest empire in the New World. Although this meteoric growth may in part be due to the adoption of innovative societal strategies, supported by a large labour force and a standing army, we argue that it would not have been possible without increased crop productivity, which was linked to more favourable climatic conditions. Here we present a multi-proxy, high-resolution 1200-year lake sediment record from Marcacocha, located 12 km north of Ollantaytambo, in the heartland of the Inca Empire. This record reveals a period of sustained aridity that began from AD 880, followed by increased warming from AD 1100 that lasted beyond the arrival of the Spanish in AD 1532.

  15. Compatibility and entry exclusion of IncA and IncC plasmids revisited: IncA and IncC plasmids are compatible.

    Ambrose, Stephanie J; Harmer, Christopher J; Hall, Ruth M

    In an early study, IncA and IncC plasmids that were reported to be compatible were grouped as the "A-C complex" based on similarities and on strong entry exclusion. However, recently, the term IncA/C has been used frequently to describe plasmids belonging to both of these two groups. Granted that the supporting data was not included in the original reports and that the consensus iteron sequences have since been shown to be essentially identical, we have addressed the question again. The original IncA plasmid, RA1, and the IncC plasmid pRMH760, were introduced into the same cell by transformation, and were found to be maintained stably for over 100 generations in the absence of selection for either plasmid, i.e. they were compatible. We conclude that use of the term IncA/C for this important plasmid group is indeed incorrect and it causes unnecessary confusion. Granted the importance of IncC plasmids in the spread of antibiotic resistance genes, we recommend that use of the misleading terms IncA/C, IncA/C 1 and IncA/C 2 should cease. In addition, RA1 and pRMH760 were shown to each completely prevent entry of the other via conjugative transfer into the cell they reside in. Copyright © 2018 Elsevier Inc. All rights reserved.

    Full Text Available This paper deals with astronomical orientation of Incas objects in Ollantaytambo, which is located about 35 km southeast from Machu Picchu, about 40 km northwest from Cusco, and lies in the Urubamba valley. Everybody writing about Ollantaytambo, shoud read Protzen. (1  He devoted his monograph to description and interpretation of that locality. Book of Salazar and Salazar (2 deals, among others, with the orientation of objects in Ollantaytambo with respect to the cardinal direction. Zawaski and Malville (3 documented astronomical context of major monuments of nine sites in Peru, including Ollantaytambo. We tested astronomical orientation in these places and confirm or disprove hypothesis about purpose of Incas objects. For assessment orientation of objects we used our measurements and also satellite images on Google Earth and digital elevation model from ASTER. The satellite images were used to estimate the astronomical-solar-solstice orientation, together with terrestrial images from Salazar and Salazar (2. The digital elevation model is useful in the mountains, where we need the actual horizon for a calculation of sunset and sunrise on specific days (solstices, which were for Incas people very important. We tested which astronomical phenomenon is connected with objects in Ollantaytambo. First, we focused on Temple of the Sun, also known the Wall of six monoliths.  We tested winter solstice sunrise and the rides of the Pleiades for the epochs 2000, 1500 and 1000 A.D. According with our results the Temple isn´t connected neither with winter solstice sunrise nor with the Pleiades. Then we tested also winter solstice sunset. We tried to use the line from an observation point near ruins of the Temple of Sun, to west-north, in direction to sunset. The astronomical azimuth from this point was about 5° less then we need. From this results we found, that is possible to find another observation point. By Salazar and Salazar (2 we found observation

    Two independent cross-sectional dietary surveys (the Individual and National Food Consumption Surveys, INCA), performed in 1998-99 (INCA1) and in 2006-07 (INCA2) on nationally representative samples of French people, were used to analyse trends in the dietary habits and nutritional intake of French adults. Food consumption was recorded through 7-d dietary records, and nutritional intakes were assessed using the French food composition database. After exclusion of under-reporters, analyses were performed on 3267 adults, aged 18-79 years: 1345 from INCA1 and 1922 from INCA2. The trends highlighted over the 8-year period showed a decrease in consumption of dairy products, meat, bread, potatoes, pastries/croissant-like pastries/cakes/biscuits and sugar/confectionery. In contrast, the consumption of fruits and vegetables, rice, ice cream and chocolate increased. Other food groups, like fish and snacking foods, remained stable. Food choices were mostly age specific. These age differences remained consistent over the years and underlined two opposite dietary trends: a 'traditional' one mainly followed by the elderly, and a 'snacking and convenience' one mainly adopted by young adults. The overall trends in food consumption did not influence the mean energy intake, but did slightly modify the contribution of each macronutrient to energy intake. These repeated surveys highlighted the fact that trends in French food habits have moved towards an average European diet at the crossroads between Mediterranean and Northern diets, and that food consumption changes impacted, to a lesser extent, nutritional intake.

    There is a need for better links between hydrology and ecology, specifically between landscapes and riverscapes to understand how processes and factors controlling the transport and storage of environmental pollution have affected or will affect the freshwater biota. Here we show how the INCA modelling framework, specifically INCA-Sed (the Integrated Catchments model for Sediments) can be used to link sediment delivery from the landscape to sediment changes in-stream. INCA-Sed is a dynamic, process-based, daily time step model. The first complete description of the equations used in the INCA-Sed software (version 1.9.11) is presented. This is followed by an application of INCA-Sed made to the River Lugg (1077 km(2)) in Wales. Excess suspended sediment can negatively affect salmonid health. The Lugg has a large and potentially threatened population of both Atlantic salmon (Salmo salar) and Brown Trout (Salmo trutta). With the exception of the extreme sediment transport processes, the model satisfactorily simulated both the hydrology and the sediment dynamics in the catchment. Model results indicate that diffuse soil loss is the most important sediment generation process in the catchment. In the River Lugg, the mean annual Guideline Standard for suspended sediment concentration, proposed by UKTAG, of 25 mg l(-1) is only slightly exceeded during the simulation period (1995-2000), indicating only minimal effect on the Atlantic salmon population. However, the daily time step simulation of INCA-Sed also allows the investigation of the critical spawning period. It shows that the sediment may have a significant negative effect on the fish population in years with high sediment runoff. It is proposed that the fine settled particles probably do not affect the salmonid egg incubation process, though suspended particles may damage the gills of fish and make the area unfavourable for spawning if the conditions do not improve.

  1. N fluxes in two nitrogen saturated forested catchments in Germany: dynamics and modelling with INCA

    2002-01-01

    Full Text Available The N cycle in forests of the temperate zone in Europe has been changed substantially by the impact of atmospheric N deposition. Here, the fluxes and concentrations of mineral N in throughfall, soil solution and runoff in two German catchments, receiving high N inputs are investigated to test the applicability of an Integrated Nitrogen Model for European Catchments (INCA to small forested catchments. The Lehstenbach catchment (419 ha is located in the German Fichtelgebirge (NO Bavaria, 690-871 m asl. and is stocked with Norway spruce (Picea abies (L. Karst. of different ages. The Steinkreuz catchment (55 ha with European beech (Fagus sylvatica L. as the dominant tree species is located in the Steigerwald (NW Bavaria, 400-460 m asl.. The mean annual N fluxes with throughfall were slightly higher at the Lehstenbach (24.6 kg N ha-1 than at the Steinkreuz (20.4 kg N ha-1. In both catchments the N fluxes in the soil are dominated by NO3. At Lehstenbach, the N output with seepage at 90 cm soil depth was similar to the N flux with throughfall. At Steinkreuz more than 50 % of the N deposited was retained in the upper soil horizons. In both catchments, the NO3 fluxes with runoff were lower than those with seepage. The average annual NO3 concentrations in runoff in both catchments were between 0.7 to 1.4 mg NO3-N L-1 and no temporal trend was observed. The N budgets at the catchment scale indicated similar amounts of N retention (Lehstenbach: 19 kg N ha-1yr-1 ; Steinkreuz: 17 kg N ha-1yr-1. The parameter settings of the INCA model were simplified to reduce the model complexity. In both catchments, the NO3 concentrations and fluxes in runoff were matched well by the model. The seasonal patterns with lower NO3 runoff concentrations in summer at the Lehstenbach catchment were replicated. INCA underestimated the increased N3 concentrations during short periods of rewetting in late autumn at the Steinkreuz catchment. The model will be a helpful tool for the

  2. Water quality improvements from afforestation in an agricultural catchment in Denmark illustrated with the INCA model

    2004-01-01

    Full Text Available Intensive agricultural land use across Europe has altered nitrogen (N budget of catchments substantially, causing widespread N pollution of freshwater. Although the N cycle in forests has changed due to increased N deposition, most forest soil waters in Europe have low nitrate concentrations. The protective function of forests on water quality has led to increasing interest in the planting of new forests on arable land as a measure to protect valuable or sensitive freshwater resources. The paper illustrates the effects of afforestation on water and N cycling using the Integrated Nitrogen Catchment (INCA model. The model was calibrated on the Horndrup catchment in the eastern part of Jutland, Denmark, which is dominated by agricultural land use but also covered by 18% of forest land. The dynamics of nitrate concentrations in the stream water were simulated successfully by INCA over a three-year period. The simulation of the dynamics of nitrate concentrations in the soil water is closely linked to the simulation of the hydrological dynamics and especially to the rainfall. The best fit was achieved for both arable and forest land during the wettest year of the study period. The model was then used to simulate the effect of afforestation of a catchment dominated by agriculture on N fluxes with seepage and runoff. Scenarios of whole catchment conversion to forest were run, based on observations of evapotranspiration and N deposition from other Danish sites. The simulated conversion to mature forest reduced runoff by 30–45% and reduced the nitrate concentrations in the soil water by 50–70%. The simulated effect of afforestation on N leaching was an almost direct reflection of the change in the N input: substantial changes in the plant demand and soil N dynamics over the afforestation period were not simulated. To simulate the N dynamics over longer time-scales, appropriate for the study of afforestation, it is suggested that the INCA model be run

    A method (INCA) is described by which signals from fixed in-core detectors are related to estimates of the three dimensional power distribution in an operating reactor core and to the maximum linear heat rate in the core. A description of the large library of data accompanying the method is provided. A detailed examination of the analytical verifications performed using the method is presented, and a summary of the uncertainty associated with the method is given. The uncertainty assigned to the maximum linear heat rate inferred by the method from operating reactor data is found to be 5.8 percent at a 95/95 confidence level. (U.S.)

    Four recently discovered frozen child mummies from two of the highest peaks in the south central Andes now yield tantalizing evidence of the preparatory stages leading to Inca ritual killing as represented by the unique capacocha rite. Our interdisciplinary study examined hair from the mummies to obtain detailed genetic and diachronic isotopic information. This approach has allowed us to reconstruct aspects of individual identity and diet, make inferences concerning social background, and gain insight on the hitherto unknown processes by which victims were selected, elevated in social status, prepared for a high-altitude pilgrimage, and killed. Such direct information amplifies, yet also partly contrasts with, Spanish historical accounts. PMID:17923675

    Full Text Available In this paper, the retaining walls in the agricultural terraces built by the Incas are analyzed from a mechanical point of view. In order to do so, ten different walls from the Lower Agricultural Sector of Machu Picchu, Perú, were selected using images from Google Street View and Google Earth Pro. Then, these walls were digitalized and their mechanical stability was evaluated. Firstly, it was found that these retaining walls are characterized by two distinctive features: disorder and a block size distribution with a large size span, i.e., the particle size varies from blocks that can be carried by one person to large blocks weighing several tons. Secondly, it was found that, thanks to the large span of the block size distribution, the factor of safety of the Inca retaining walls is remarkably close to those that are recommended in modern geotechnical design standards. This suggests that these structures were not only functional but also highly optimized, probably as a result of a careful trial and error procedure.

    The Radiotherapy Quality Program (PQRT) of Cancer National Institute (INCA) has been functioning since 1999 as a pilot program with only 33 participant institutions. Due to the optimal obtained results the program becomes a part of the INCA National Programs and his activities were extended to all radiotherapy services which attend the Health Unique Systems (SUS), approximately 130 institutions corresponding to 90 percent of the radiotherapy services available in Brazil. The PQRT main objective is to make the radiotherapy to be evaluated as planned, in accordance with quality assurance international standards. The principal activities of the PQRT are: local evaluation, TLD postal evaluation under reference and non-reference conditions, and training and development of research projects. The Local Evaluation System has already evaluated 85 teletherapy equipment (38 Co-60 and 47 linear accelerators), executing dosimetric, electric, mechanic and safety tests. The TLD postal system used for the 33 participants until 2002 was the International Atomic Energy Agency (IAEA) for reference conditions. Five evaluations has already been performed with this simply system. Since 2003, the postal evaluation of the PQRT is using his own system, developed for reference and non-reference conditions, applied to 58 beams (18 Co-60 and 40 linear accelerators). The PQRT ras already performed 400 evaluations under reference conditions (190 Co-60 and 210 linear accelerators). 18 courses have been provided for the participants, covering his main practical problems. In addition, some studies and research has been performed

    Full Text Available Information Technologies can provide the basis for new directions in cancer research, supplying tools that identify subtle but important signs from the analysis of clinical, behavioral, environmental and genetic data. The purpose of this paper is to describe and analyze the system developed for managing Banco Nacional de Tumores (SISBNT – National Tumor Bank System - highlighting its role in the technological innovation of Instituto Nacional do Câncer (INCA – Brazilian National Cancer Institute. It is a qualitative empirical theoretical paper, descriptive and exploratory in nature, based on the single case study method and on participant observation. The results show the importance of good practices in information management for the full operation of a biobank in a research-oriented pharmaceutical company. There is also evidence that the implementation of SISBNT has contributed to the improvement of cancer treatment quality and to the support of efforts towards the organization of the integration of clinical, translational and basic research. The non-use of data mining techniques for the identification of molecular patterns and structures associated with the different types of cancer undergoing study at INCA seems to occur due to the early stage of Bioinformatics and translational research, as well as the National Tumor Bank, in the institution.

  8. INCA Modelling of the Lee System: strategies for the reduction of nitrogen loads

    Science.gov (United States)

    Flynn, N. J.; Paddison, T.; Whitehead, P. G.

    The Integrated Nitrogen Catchment model (INCA) was applied successfully to simulate nitrogen concentrations in the River Lee, a northern tributary of the River Thames for 1995-1999. Leaching from urban and agricultural areas was found to control nitrogen dynamics in reaches unaffected by effluent discharges and abstractions; the occurrence of minimal flows resulted in an upward trend in nitrate concentration. Sewage treatment works (STW) discharging into the River Lee raised nitrate concentrations substantially, a problem which was compounded by abstractions in the Lower Lee. The average concentration of nitrate (NO3) for the simulation period 1995-96 was 7.87 mg N l-1. Ammonium (NH4) concentrations were simulated less successfully. However, concentrations of ammonium rarely rose to levels which would be of environmental concern. Scenarios were run through INCA to assess strategies for the reduction of nitrate concentrations in the catchment. The conversion of arable land to ungrazed vegetation or to woodland would reduce nitrate concentrations substantially, whilst inclusion of riparian buffer strips would be unsuccessful in reducing nitrate loading. A 50% reduction in nitrate loading from Luton STW would result in a fall of up to 5 mg N l-1 in the reach directly affected (concentrations fell from maxima of 13 to 8 mg N l-1 , nearly a 40 % reduction), whilst a 20% reduction in abstractions would reduce maximum peaks in concentration in the lower Lee by up to 4 mg l-1 (from 17 to 13 mg N l-1, nearly a 25 % reduction),.

  9. Shadow corrosion testing in the INCA facility in the Studsvik R2 reactor

    Shadow corrosion is a phenomenon which occurs when zirconium alloys are in contact with or in proximity to other metallic objects in a boiling water reactor environment (BWR, RBMK, SGHWR etc.). An enhanced corrosion occurs on the zirconium alloy with the appearance of a 'shadow' of the metallic object. The magnitude of the shadow corrosion can be significant, and is potentially limiting for the lifetime of certain zirconium alloy components in BWRs and other reactors with a similar water chemistry. In order to evaluate the suitability of the In-Core Autoclave (INCA) in the Studsvik R2 materials testing reactor as an experimental facility for studying shadow corrosion, a demonstration test has been performed. A number of test specimens consisting of Zircaloy-2 tubing in contact with Inconel were exposed in an oxidising water chemistry. Some of the specimens were placed within the reactor core and some above the core. The conclusion of this experiment after post irradiation examination is that it is possible to use the INCA facility in the Studsvik R2 reactor to develop a significant level of shadow corrosion after only 800 hours of irradiation.

    This study will focus on frozen mummies of sacrificial victims from mounts Llullaillaco (6739 m), Quehuar (6130 m), El Toro (6160 m), and the Aconcagua massif. These finds provide bioarchaeological data from mountaintop sites that has been recovered in scientifically controlled excavations in the northwest of Argentina, which was once part of the southern province of the Inca Empire. Numerous interdisciplinary studies have been conducted on the Llullaillaco mummies, including radiological evaluations by conventional X-rays and CT scans, which provided information about condition and pathology of the bones and internal organ, as well as dental studies oriented to the estimation of the ages of the three children at the time of death. Ancient DNA studies and hair analysis were also performed in cooperation with the George Mason University, the University of Bradford, and the Laboratory of Biological Anthropology at the University of Copenhagen. Ethnohistorical sources reveal interesting aspects related to the commemorative, expiatory, propitiatory, and dedicatory aspects of human sacrifice performed under Inca rule. The selection of the victims along with the procedures followed during the performance of the capacocha ceremony will be discussed, based on the bioarchaeological evidences from frozen mummies and the accounts recorded by the Spanish chroniclers.

    The Inca Historical Sanctuary of Machu Picchu (Peru) is a large archaeological area (ca. 30 sq km) located in the Andean chain in the region of Cuzco, in the high Eastern Cordillera, a Permo-Liassic rift system including a variety of rock types, dominantly granites and granodiorites. The seismicity of the area is mainly connected to the main Quaternary faults systems of the Cuzco region that have caused in the past the most destructive earthquakes, generally characterised by superficial hypocentres. The sanctuary , located along the Urubamba River Valley (NW orientation), includes, besides the well-known Machu Picchu citadel, several "minor" archaeological sites, located in the forest area, reciprocally connected by the "Inca trail". The elevation varies from 4,000 to 1,700m a.s.l. The slope gradient is generally very high, with average slope angle >40°. Due to geological and sub-tropical climate characteristics, the granitoid rocks usually develop a heavily weathered soil cover of 1-2m depth along the slopes. Geomorphological evidences from bibliography, field surveys and aerial photo analysis report shallow landslides (mostly debris flows) triggered by heavy rainfall as the most frequent landslide types. Landslides potential failure surface usually corresponds to the contact between soil cover and granitoid bedrock (1-2m depth). Slope movements are triggered by pore pressure increase due to rapid infiltration of rainfall along the slopes that usually exhibit a scarcely developed drainage system. After the initial mobilisation, a rapid failure and displacement occur in a chaotic mixture of coarse and fine materials, from silty-sands to rock blocks. Shallow landslides may cause severe damage to the archaeological sites of the Inca sanctuary that present slope deformation and active strain processes in the ancient structures. The general homogeneity of the area in terms of outcropping soil types, morphology and climate conditions promote shallow landslides

    Chlamydophila (Cp.) psittaci, the causative agent of psittacosis in birds and humans, is the most important zoonotic pathogen of the family Chlamydiaceae. These obligate intracellular bacteria are distinguished by a unique biphasic developmental cycle, which includes proliferation in a membrane-bound compartment termed inclusion. All Chlamydiaceae spp. possess a coding capacity for core components of a Type III secretion apparatus, which mediates specific delivery of anti-host effector proteins either into the chlamydial inclusion membrane or into the cytoplasm of target eukaryotic cells. Here we describe the interaction between Type III-secreted protein IncA of Cp. psittaci and host protein G3BP1 in a yeast two-hybrid system. In GST-pull down and co-immunoprecipitation experiments both in vitro and in vivo interaction between full-length IncA and G3BP1 were shown. Using fluorescence microscopy, the localization of G3BP1 near the inclusion membrane of Cp. psittaci-infected Hep-2 cells was demonstrated. Notably, infection of Hep-2 cells with Cp. psittaci and overexpression of IncA in HEK293 cells led to a decrease in c-Myc protein concentration. This effect could be ascribed to the interaction between IncA and G3BP1 since overexpression of an IncA mutant construct disabled to interact with G3BP1 failed to reduce c-Myc concentration. We hypothesize that lowering the host cell c-Myc protein concentration may be part of a strategy employed by Cp. psittaci to avoid apoptosis and scale down host cell proliferation.

  17. Long-term modelling of nitrogen turnover and critical loads in a forested catchment using the INCA model

    Full Text Available Many forest ecosystems in Central Europe have reached the status of N saturation due to chronically high N deposition. In consequence, the NO3 leaching into ground- and surface waters is often substantial. Critical loads have been defined to abate the negative consequences of the NO3 leaching such as soil acidification and nutrient losses. The steady state mass balance method is normally used to calculate critical loads for N deposition in forest ecosystems. However, the steady state mass balance approach is limited because it does not take into account hydrology and the time until the steady state is reached. The aim of this study was to test the suitability of another approach: the dynamic model INCA (Integrated Nitrogen Model for European Catchments. Long-term effects of changing N deposition and critical loads for N were simulated using INCA for the Lehstenbach spruce catchment (Fichtelgebirge, NE Bavaria, Germany under different hydrological conditions. Long-term scenarios of either increasing or decreasing N deposition indicated that, in this catchment, the response of nitrate concentrations in runoff to changing N deposition is buffered by a large groundwater reservoir. The critical load simulated by the INCA model with respect to a nitrate concentration of 0.4 mg N l–1 as threshold value in runoff was 9.7 kg N ha–1yr–1 compared to 10 kg ha–1yr–1 for the steady state model. Under conditions of lower precipitation (520 mm the resulting critical load was 7.7 kg N ha–1yr–1 , suggesting the necessity to account for different hydrological conditions when calculating critical loads. The INCA model seems to be suitable to calculate critical loads for N in forested catchments under varying hydrological conditions e.g. as a consequence of climate change.

    Full Text Available Continuing deposition of nitrogen in forested catchments affects stream and groundwater quality. However, the dependence of nitrogen dynamics on climatic and hydrological boundary conditions is still poorly understood. These dynamics have been investigated by applying the process-oriented Integrated Nitrogen in CAtchments (INCA model and an artificial neural network to the data set from the forested Steinkreuz catchment in South Germany. The data comprise daily values of precipitation, air temperature and discharge of the catchment runoff. The INCA model simulated the mean nitrate concentration in the stream as well as seasonal fluctuations but it underestimated the short-term variance of the observed stream water nitrate concentration, especially the pronounced concentration peaks in late summer. In contrast, the artificial neural network matched the short-term dynamics using non-linear regressions with stream discharge and air temperature data. The results provide strong evidence that the short-term dynamics of stream nitrate concentration during storm-flow were generated in the riparian zone, which is less than 1% of the catchment area, and is not considered explicitly in the INCA model. The concentration peaks have little effect on the catchment’s nitrogen budget and the shallow groundwater data suggest that the short-term hydrological dynamics also govern groundwater recharge in the upland parts of the catchment. This substantial underestimate by the INCA model parameterisation is balanced by a corresponding underestimate of denitrification in clayey layers of the deeper aquifer. A better understanding of these processes is necessary to improve long-term risk assessments. Keywords: catchment, runoff, nitrogen, INCA, artificial neural network, flushing

    We describe attempts to construct a phenomenologically viable model which embeds a unified theory of strong, weak and electromagnetic interactions in an extended supergravity theory. Following Cremmer and Julia, we assume that the local unitary symmetry which they found for SO(N) supergravity theories is realized dynamically, and that the usual quarks, leptons, gauge bosons and Higgs scalars of the renormalizable gauge theory are composite states which appear point-like on a mass scale below the Planck mass. We argue that this picture leads uniquely to SO(8) (or SO(7)) supergravity with SU(5) as the grand unification gauge group. We find that conventional symmetry breaking schemes according to which particles acquire all allowed invariant masses at each stage of a step by step symmetry breakdown do not yield an acceptable particle spectrum. We argue that the original symmetries of the composite supermultiplet may break dynamically to an effective anomaly free renormalizable sub-theory, with the underlying supersymmetry serving at most to restrict the particle spectrum and to specify the couplings of the effective renormalizable Lagrangian at the Planck mass. Preliminary investigations suggest that this approach may be more promising

  20. Inca Trail porters: the health of local tourism employees as a challenge for travel medicine.

    2003-01-01

    Trekking is an activity that forms part of the increasing adventure and outdoor tourism. High altitude trekking in the Himalayas or Andes has been popular for some time. For longer treks, porters are employed to carry necessary equipment. Porters' working conditions are unfortunate and subsequent health problems considerable. Although Himalayan porters have received some attention in the press and research literature, porters on the popular Inca Trail in Peru have been neglected. In light of the growing awareness of health problems of local tourism employees, the purpose of this study was to describe Inca Trail porters' working conditions and their reports on their related health status to provide baseline information for further research and strategies for improvement. For this descriptive study, 101 Inca Trail porters were interviewed (August/September 2001) using a structured interview schedule. Porters were between 17 and 68 years old; estimated body weight ranged from 50 kg to 76 kg. The usual portering job lasts for 4 days with 9 to 10 hours of carrying per day. Estimated weight of loads ranged from 20 kg to 45 kg. Major concerns were lack of fuel, clothes, shelter, and equipment but foremost the lack of sufficient food provisions. A third described their general health as poor or very poor and attributed this to work. Health complaints included respiratory infections, kidney problems, or rheumatism. Thirty-eight porters recalled injuries while on the trail and over 90% had fallen ill on the job with cold, "majurki," and stomach pain due to lack of food or cold food being named most often. Porters' demands for improvement included increased pay and appropriate and sufficient food. The porters' working conditions and subsequent health problems need to be addressed. A range of stakeholders is responsible for the porters' conditions and are in a position to improve current situations. Specific responsibility for health care lies with travel health professionals

    Full Text Available Witkacy’s Pure Form expresses the metaphysical essence of art. On the one side, it symbolizes the structure of the world, the unity in plurality (which is demonstrated in the picture’s composition and, on the other, the notion deals with the processes of creating and perceiving an art work. The moment in which the self feels itself embedded in the wholeness of the world is the moment in which the metaphysical feeling arises, and in which the experience of art is fulfilled. Witkacy provides many examples for situations evoking this feeling. He describes them in his novels, he finds synonyms as suchness, curiosity of existence, mystery of being or unity of identity, he switches from scientific to poetic language. And he emphasizes that this feeling, while defying verbalization, is a real, not a supernatural one: a psychophysical phenomenon accessible to introspection, and inseparable from one's cultural and individual background.

  4. The Context for IMAP: Voyager and INCA Observations of the Heliosheath at E > 5 keV

    2016-04-01

    The basic premise of the proposed Interstellar Mapping and Acceleration Probe (IMAP) is detailed scientific understanding of the Heliosheath (HS) and beyond, a region of space explored in situ by Voyager 1 (V1) since 2004, Voyager 2 (V2) since 2007, and remotely via energetic neutral atoms (ENA) by the Cassini/INCA (Ion and Neutral CAmera) since 2003 and IBEX since 2009. The IMAP instrumentation proposed for this purpose combines and extends the IBEX and INCA ENA energy ranges (0.3- 20 keV and 3-200 keV, for low and high energy, respectively). All three missions-Voyagers, Cassini/INCA, and IBEX- have made discovery-class measurements in the HS, the Voyagers providing in situ ion intensities at E > 30 keV, while INCA images ENA in the range 5 INCA ENA allows for the possibility of observing the intensity and time evolution of ions in the HS, thought to give rise to the ENAs via charge-exchange, and the resultant ENA images in the inner heliosphere and their spatial and/or temporal variability. Unfortunately, no such "ground truth" ion measurements are possible at Voyager in the ENA energy range imaged by IBEX. Some of the key findings from the Voyager and Cassini/INCA measurements are as follows: (1) The HS contains a hot plasma population that carries a substantial part (30-50 %) of the total pressure at E > 5 keV, the rest residing below that range, resulting in a beta (particle/magnetic pressure) always > 1, typically >10. (2) The width of the HS in the direction of V1 is ~ 30 AU, but is thought to be larger (40-70 AU) in the southern ecliptic where V2 currently travels.. (3) The ENA intensities at E > 5 keV exhibit a correlation with the solar cycle (SC) over the period 2003 to 2015, with minimum intensities in the anti-nose direction observed ~ 1.5 yrs after solar minimum followed by a recovery thereafter. (4) The in situ ion measurements at V2 within the HS also show a similar SC dependence. The totality of the observations, together with the near

    Full Text Available Excess nitrogen in soils, fresh water, estuarine and marine systems contributes to nutrient enrichment in key ecosystems throughout Europe, often leading to detrimental environmental impacts, such as soil acidification or the eutrophication of water bodies. The Integrated Nitrogenmodel for European Catchments (INCA project aims to develop a generic version of the Integrated Nitrogen in Catchments (INCA model to simulate the retention and transport of nitrogen within river systems, thereby providing a tool to aid the understanding of nitrogen dynamics and for river-basin management/policy-making. To facilitate the development of the model, 10 partners have tested the INCA model with data collected in study sites located in eight European countries as part of the INCA project. This paper summarises the key nitrogen issues within Europe, describes the main aims and methodology of the INCA project, and sets the project in the context of the current major research initiatives at a European level. Keywords: Europe, European Union, nitrogen, nitrate, ammonium, river basin management, modelling, water chemistry, acidification, eutrophication, Water Framework Directive, INCA.

  7. Inhibition of Fusion of Chlamydia trachomatis Inclusions at 32°C Correlates with Restricted Export of IncA

    Chlamydia trachomatis is an obligate intracellular bacterium that develops within a parasitophorous vacuole termed an inclusion. The inclusion is nonfusogenic with lysosomes but intercepts lipids from a host cell exocytic pathway. Initiation of chlamydial development is concurrent with modification of the inclusion membrane by a set of C. trachomatis-encoded proteins collectively designated Incs. One of these Incs, IncA, is functionally associated with the homotypic fusion of inclusions. Incl...

  8. Modelling the long term impact of climate change on the carbon budget of Lake Simcoe, Ontario using INCA-C.

    This study presents a process-based model of dissolved organic carbon concentration ([DOC]) in catchments draining into Lake Simcoe, Ontario. INCA-C, the Integrated Catchment model for Carbon, incorporates carbon biogeochemical processes in a terrestrial system with hydrologic flow paths to simulate watershed wide [DOC]. The model successfully simulates present-day inter-annual and seasonal [DOC] dynamics in tributaries draining catchments with mixed or contrasting land cover in the Lake Simcoe watershed (LSW). The sensitivity of INCA-C to soil moisture, hydrologic controls and land uses within a watershed demonstrates its significance as a tool to explore pertinent environmental issues specific to the LSW. Projections of climate change under A1B and A2 SRES scenarios suggest a continuous monotonic increase in [DOC] in surface waters draining into Lake Simcoe. Large variations in seasonal DOC dynamics are predicted to occur during summer with a possibility of displacement of summer [DOC] maxima towards winter and a prolongation of summer [DOC] levels into the autumn. INCA-C also predicts possible increases in dissolved inorganic carbon in some tributaries with rising temperature suggesting increased CO(2) emissions from rivers as climate changes.

    2004-01-01

    A new version (v1.7) of the Integrated Nitrogen in CAtchments model(INCA) was applied to the northern boreal Simojoki river basin (3160 km 2 ) in Finland. The INCA model is a semi-distributed, dynamic nitrogen (N) process model which simulates N transport and processes in catchments. The INCA model was applied to model flow and seasonal inorganic N dynamics of the river Simojoki basin over the period 1994-1996, and validated for two more years. Both calibration and validation of the model were successful. The model was able to simulate annual dynamics of inorganic N concentrations in the river. The effects of forest management and atmospheric deposition on inorganic N fluxes to the sea in 2010 were studied. Three scenarios were applied for forestry practices and two for deposition. The effects of forest cutting scenarios and atmospheric deposition scenarios on inorganic N flux to the sea were small. The combination of the maximum technically possible reduction of N deposition and a decrease of 100% in forest cutting and peat mining areas decreased NO 3 - -N flux by 6.0% and NH 4 + -N flux by 3.1%

    Although theorists have posited that suicidal individuals are more likely than non-suicidal individuals to experience cognitive distortions, little empirical work has examined whether those who recently attempted suicide are more likely to engage in cognitive distortions than those who have not recently attempted suicide. In the present study, 111 participants who attempted suicide in the 30 days prior to participation and 57 psychiatric control participants completed measures of cognitive distortions, depression, and hopelessness. Findings support the hypothesis that individuals who recently attempted suicide are more likely than psychiatric controls to experience cognitive distortions, even when controlling for depression and hopelessness. Fortune telling was the only cognitive distortion uniquely associated with suicide attempt status. However, fortune telling was no longer significantly associated with suicide attempt status when controlling for hopelessness. Findings underscore the importance of directly targeting cognitive distortions when treating individuals at risk for suicide.

Cobo et de Garcilaso de la Vega, relatifs aux charpentes incas, et des charpentes actuelles, observées dans le village de Wayllabamba, situé dans la parc archéologique de Machu Picchu. Ces charpentes font appel à un élément porteur original, constitué par trois perches réunies à leurs extrémités supérieures. Ce système paraît correspondre aux descriptions des chroniqueurs et iI semble probable qu'il s'agisse donc d'un phénomène de perdurance des techniques précolombiennes de charpenterie. L'auteur aborde ensuite le problème de la couverture d'édifices incas de grandes dimensions il souligne la possibilité technique de couvrir ces édifices. Enfin, une troisième partie est consacrée à la mise en relation des propriétés des murs porteurs et de celles de la toiture, dont les qualités isothermiques se complètent. L'habitation andine apparaît donc comme une solution très satisfaisante en réponse au climat contrasté des Andes péruviennes. En la sierra peruana, los edificios incaicos muestran solamente materiales inorgánicos aparte de escasos elementos, como algunos dinteles de madera, los materiales orgánicos han desaparecido después que los habitantes abandonaron esos edificios. El estudio de las techumbres incaicas se tiene que hacer con otros datos que los vestigios arqueológicos. La primera parte del presente informe relaciona tres textos, de B. Cobo y de Garcilaso de la Vega, que describen armazones incaicas, con observaciones hechas por el autor acerca de unos armazones actuales.

El elemento básico es un elemento trípode que reemplaza las armaduras triangulares formadas por un tirante y dos alfardas. Este sistema se asemeja a los descritos por Cobo y por Garcilaso y probablemente es prehispánico. La segunda parte enfoca el asunto de la techumbre de los edificios de gran dimensi

    The nudged atmosphere global climate model LMDzT-INCA is used to forecast global dust fields. Evaluation is undertaken in retrospective for the forecast results of the year 2006. For this purpose AERONET/Photons sites in Northern Africa and on the Arabian Peninsula are chosen where aerosol optical depth is dominated by dust. Despite its coarse resolution, the model captures 48% of the day to day dust variability near Dakar on the initial day of the forecast. On weekly and monthly scale the model captures respectively 62% and 68% of the variability. Correlation coefficients between daily AOD values observed and modelled at Dakar decrease from 0.69 for the initial forecast day to 0.59 and 0.41 respectively for two days ahead and five days ahead. If one requests that the model should be able to issue a warning for an exceedance of aerosol optical depth of 0.5 and issue no warning in the other cases, then the model was wrong in 29% of the cases for day 0, 32% for day 2 and 35% for day 5. A reanalysis run with archived ECMWF winds is only slightly better (r=0.71) but was in error in 25% of the cases. Both the improved simulation of the monthly versus daily variability and the deterioration of the forecast with time can be explained by model failure to simulate the exact timing of a dust event.

    Effects of different solvents, ionic strength, and pH on Inca peanut seed protein solubility were assessed by quantitatively analyzing solubilized proteins using Lowry and Bradford methods. Soluble proteins were fractionated using Osborne procedure and the polypeptide composition of solubilized proteins was determined by one dimensional 25 % monomer acrylamide linear gradient SDS-PAGE. Osborne protein fractions were analyzed by the 2D gel electrophoresis. Total seed proteins were efficiently solubilized by 2 M NaCl among the tested solvents. The soluble seed proteins registered a minimum solubility at pH ~4.0. Osborne protein fractions, albumins, globulins, prolamins, and glutelins accounted for 43.7, 27.3, 3.0, and 31.9 %, respectively, of the total aqueous soluble proteins. Soluble seed flour proteins are mainly composed of polypeptides in the MW range of 6-70 kDa of which the predominant polypeptides were in the 20-40 kDa range. Prolamin fraction was mainly composed of four polypeptides (MW < 15 kDa). Glycoprotein staining indicated 32-35 and <14 kDa peptides to be positive.

    Full text of publication follows: The Mini-INCA project is devoted to precise description of the transmutation chain of Actinides within high thermal neutron fluxes. It uses the High Flux Reactor of ILL (Laue Langevin Institute) as an intense thermal neutron source to measure capture and fission cross sections. Two irradiation channels are dedicated for those measurements offering a diversity of fluxes ranging from pure thermal neutrons to 15% epithermal neutrons with intensities as high as 1*10 15 n/cm 2 /s. Standard nuclear techniques for measurements, such as α and γ-spectroscopy of irradiated samples, have been extended in order to stand all constraints due to the irradiation in high fluxes. In particular new types of fission micro-chambers have been developed to follow online the evolution of one actinide and to measure its fission cross section in reference to 235 U(n,F) standard reaction. This type of neutron detector will be used within the MEGAPIE target to on-line characterise the neutron flux and to study the potentiality of such target in terms of incineration. (author)

    Chlamydia (C.) pecorum, an obligate intracellular bacterium, may cause severe diseases in ruminants, swine and koalas, although asymptomatic infections are the norm. Recently, we identified genetic polymorphisms in the ompA, incA and ORF663 genes that potentially differentiate between high-virulence C. pecorum isolates from diseased animals and low-virulence isolates from asymptomatic animals. Here, we expand these findings by including additional ruminant, swine, and koala strains. Coding tandem repeats (CTRs) at the incA locus encoded a variable number of repeats of APA or AGA amino acid motifs. Addition of any non-APA/AGA repeat motif, such as APEVPA, APAVPA, APE, or APAPE, associated with low virulence (PincA CTRs (P = 0.0028). In ORF663, high numbers of 15-mer CTRs correlated with low virulence (P = 0.0001). Correction for ompA phylogram position in ORF663 and incA abolished the correlation between genetic changes and virulence, demonstrating co-evolution of ompA, incA, and ORF663 towards low virulence. Pairwise divergence of ompA, incA, and ORF663 among isolates from healthy animals was significantly higher than among strains isolated from diseased animals (P≤10-5), confirming the longer evolutionary path traversed by low-virulence strains. All three markers combined identified 43 unique strains and 4 pairs of identical strains among all 57 isolates tested, demonstrating the suitability of these markers for epidemiological investigations.

Ces témoignages directs, confrontés avec d'autres contemporains, constituent de nouveaux éléments inédits pour éclairer la version donnée par les sources espagnoles de cette époque ils font connaître également, et presque en détail, les négociations du vice-roi Marquis de Cañete, lequel se proposait d'en finir pacifiquement avec la résistance héroïque de Vilcabamba, ainsi que la prudence Inca pour déjouer ce plan et éviter les dangers d'une guerre contre ce dernier réduit du Tawantinsuyo. Il ressort de ces témoignages, comparés avec d'autres fiables que nous avons consultés, la mise en question de la vérité sur la succession de Sayri Thupa à la mort de son père, Manko Inka, et la possibilité que le jeune auki ait simulé cette fonction par le truchement d'un artifice politique de la Cour de Vilcabamba. Se publican en este artículo las declaraciones de tres testigos presenciales de los sucesos de 1533 a 1558, es decir desde la entrada de Manko Inka Yupanki al Cusco, con sus aliados españoles, hasta la 'salida' del auki Sayri Thupa, -uno de sus hijos- en 1558, ante la presión militar y diplomática del Marqués de Cañete. Estos testimonios directos, confrontados con otros coetáneos, constituyen nuevos e inéditos elementos de juicio para aclarar la versión de las fuentes hispanas de estos años y para conocer casi en detalle las negociaciones del virrey Marqués de Cañete, que se proponía acabar pacíficamente con la resistencia heroica de Vilcabamba, y la cautela Inca para burlar este propósito y evitar los peligros de una guerra contra este último reducto del Tawantinsuyo

    Full Text Available Chlamydia trachomatis is an obligate, intracellular bacterial pathogen that has until more recently remained recalcitrant to genetic manipulation. However, the field still remains hindered by the absence of tools to create selectable, targeted chromosomal mutations. Previous work with mobile group II introns demonstrated that they can be retargeted by altering DNA sequences within the intron's substrate recognition region to create site-specific gene insertions. This platform (marketed as TargeTron™, Sigma has been successfully employed in a variety of bacteria. We subsequently modified TargeTron™ for use in C. trachomatis and as proof of principle used our system to insertionally inactivate incA, a chromosomal gene encoding a protein required for homotypic fusion of chlamydial inclusions. C. trachomatis incA::GII(bla mutants were selected with ampicillin and plaque purified clones were then isolated for genotypic and phenotypic analysis. PCR, Southern blotting, and DNA sequencing verified proper GII(bla insertion, while continuous passaging in the absence of selection demonstrated that the insertion was stable. As seen with naturally occurring IncA(- mutants, light and immunofluorescence microscopy confirmed the presence of non-fusogenic inclusions in cells infected with the incA::GII(bla mutants at a multiplicity of infection greater than one. Lack of IncA production by mutant clones was further confirmed by Western blotting. Ultimately, the ease of retargeting the intron, ability to select for mutants, and intron stability in the absence of selection makes this method a powerful addition to the growing chlamydial molecular toolbox.

    Full Text Available As a first step in applying the Integrated Nitrogen model for CAtchments (INCA to the Simojoki river basin (3160 km2, this paper focuses on calibration of the hydrological part of the model and nitrogen (N dynamics in the river during the 1980s and 1990s. The model application utilised the GIS land-use and forest classification of Finland together with a recent forest inventory based on remote sensing. In the INCA model, the Hydrologically Effective Rainfall (HER is used to drive the water flow and N fluxes through the catchment system. HER was derived from the Watershed Simulation and Forecast System (WSFS. The basic component of the WSFS is a conceptual hydrological model which simulates runoff using precipitation, potential evapotranspiration and temperature data as inputs. Spatially uniform, lumped input data were calculated for the whole river basin and spatially semi-distributed input data were calculated for each of the nine sub-basins. When comparing discharges simulated by the INCA model with observed values, a better fit was obtained with the semi-distributed data than with the spatially uniform data (R2 0.78 v. 0.70 at Hosionkoski and 0.88 v. 0.78 at the river outlet. The timing of flow peaks was simulated rather well with both approaches, although the semi-distributed input data gave a more realistic simulation of low flow periods and the magnitude of spring flow peaks. The river basin has a relatively closed N cycle with low input and output fluxes of inorganic N. During 1982-2000, the average total N flux to the sea was 715 tonnes yr–1, of which 6% was NH4-N, 14% NO3-N, and 80% organic N. Annual variation in river flow and the concentrations of major N fractions in river water, and factors affecting this variation are discussed.

    The advent of Energetic Neutral Atom (ENA) imaging, (the result of charge-exchange with energetic ions), has revealed the global nature of the heliosheath (HS) at both high ( > 5 keV, Cassini from 10 AU) and low (INCA (Ion and Neutral CAmera) since 2003 with a full image available since 2009, when IBEX global imaging observations also became available. The presence of the two Voyagers measuring ions locally in the HS contemporaneously with INCA global imaging through ENA in overlapping energy bands provides a powerful tool for examining the spatial, temporal, and spectral evolution of the source hot plasma ions and the global variability of the neutral component. Some of the key findings from the Voyagers and INCA measurements are as follows: (a) The HS contains a hot plasma population that carries a substantial part (30-50%) of the total pressure at E > 5 keV, the rest residing below that range, resulting in a beta (particle/magnetic pressure) always > 1, typically > 10. (b) The width of the HS in the direction of V1 is ˜~ 30 AU, but is thought to be larger (40-70 AU) in the southern ecliptic where V2 currently travels. (c) The ENA intensities at E > 5 keV exhibit a correlation with the solar cycle (SC) over the period 2003 to 2014, with minimum intensities in the anti-nose direction observed ˜~ 1.5 yrs after solar minimum followed by a recovery thereafter, and (d) The in situ ion measurements at V2 within the HS also show a similar SC dependence. The totality of the observations, together with the near-contemporaneous variability in intensities of ions in situ in the HS and ENA in the inner heliosphere suggests that the source of such emissions at E > 5 keV must reside in the HS. These observations constrain the shape of the HS and suggest configurations that are at some variance with current models.

    Full Text Available Chlamydia (C. pecorum, an obligate intracellular bacterium, may cause severe diseases in ruminants, swine and koalas, although asymptomatic infections are the norm. Recently, we identified genetic polymorphisms in the ompA, incA and ORF663 genes that potentially differentiate between high-virulence C. pecorum isolates from diseased animals and low-virulence isolates from asymptomatic animals. Here, we expand these findings by including additional ruminant, swine, and koala strains. Coding tandem repeats (CTRs at the incA locus encoded a variable number of repeats of APA or AGA amino acid motifs. Addition of any non-APA/AGA repeat motif, such as APEVPA, APAVPA, APE, or APAPE, associated with low virulence (P<10-4, as did a high number of amino acids in all incA CTRs (P = 0.0028. In ORF663, high numbers of 15-mer CTRs correlated with low virulence (P = 0.0001. Correction for ompA phylogram position in ORF663 and incA abolished the correlation between genetic changes and virulence, demonstrating co-evolution of ompA, incA, and ORF663 towards low virulence. Pairwise divergence of ompA, incA, and ORF663 among isolates from healthy animals was significantly higher than among strains isolated from diseased animals (P≤10-5, confirming the longer evolutionary path traversed by low-virulence strains. All three markers combined identified 43 unique strains and 4 pairs of identical strains among all 57 isolates tested, demonstrating the suitability of these markers for epidemiological investigations.

    Disease detection in ancient human samples currently relies on genomic-based assays, which are error prone due to contamination and cannot distinguish between active and latent pathogenic infection. On the other hand, protein-based assays such as global protein profiling offer complementary alternatives for the pathological diagnosis of archeological specimen. The discovery of three Inca mummies in 1998, perfectly preserved in the permafrost of the high Andes, allowed us to analyze mummy samples by protein-based and genomic-based assay. A buccal swab from one of the 500 year old mummy was analyzed by shotgun proteomics to detect the protein profile. Among the identified proteins, we found a signature of proteins indicating an immune response to a bacterial infection at the time of the mummy's death. Based on the external visible symptoms and the gamut of immune response proteins obtained from the mouth swab, we suspected that the pulmonary infection was caused by Mycobacterium. PCR assay followed by direct sequencing of the PCR products confirmed the presence of Mycobacterium sp. in the mouth swab. Until now, immunoassays have been the only way to detect an active immune response and infer infection in historical samples, but these were plagued by low specificity and sensitivity. However, we demonstrate here the feasibility of incorporating global protein profiling in the diagnosis of infection from archeological samples. Protein signatures obtained from these samples could be extremely useful in determining the status of infection while genomic-based assays can be used to detect the identity of the pathogen.

    To evaluate the treatment of GIST in INCA. We conducted a retrospective analysis of all cases of GIST treated at INCA in the period from 1997 to 2009. We analyzed 146 patients with a mean age of 44.5 years and female predominance. The main symptom was abdominal pain. We observed the occurrence of a second primary tumor in 22% of cases and 92% of the immunohistochemistry exams were positive for CD117. The most frequent location was in the stomach and the high-risk group was predominant. Surgery was considered R0 (extensive) in 70% of the cases and the main sites of metastases were liver and peritoneum. Overall survival in two and five years was, respectively, 86% and 59%. There was a significant difference between overall survival (p = 0.29) of the high-risk group versus the other. Our patients presented mainly in the form of high-risk disease, with obvious impact on survival. The use of imatinib improved survival of patients with recurrent and metastatic disease. We should study its use in the setting of adjuvant and neoadjuvant therapy to improve results of the high risk group. The creation of reference centers is a need for the study of rare diseases.

    A definition of time intervals separating two states of systems of elementary particles and observers is attempted. The definition is founded on the notion of instant state of the system and uses no information connected with the use of a clock. Applying the definition to a classical clock and to a sample of unstable particles, results are obtained in agreement with experiment. However, if the system contains 'few' elementary particles, the properties of the time interval present some different features. (author)

  18. Destabilization of IncA and IncC plasmids by SGI1 and SGI2 type Salmonella genomic islands.

    Harmer, Christopher J; Hamidian, Mohammad; Ambrose, Stephanie J; Hall, Ruth M

    Both the Salmonella genomic islands (SGI) and the conjugative IncC plasmids are known to contribute substantially to the acquisition of resistance to multiple antibiotics, and plasmids in the A/C group are known to mobilize the Salmonella genomic island SGI1, which also carries multiple antibiotic resistance genes. Plasmid pRMH760 (IncC; A/C 2 ) was shown to mobilize SGI1 variants SGI1-I, SGI1-F, SGI1-K and SGI2 from Salmonella enterica to Escherichia coli where it was integrated at the preferred location, at the end of the trmE (thdF) gene. The plasmid was transferred at a similar frequency. However, we observed that co-transfer of the SGI and the plasmid was rarer. In E. coli to E. coli transfer, the frequency of transfer of the IncC plasmid pRMH760 was at least 1000-fold lower when the donor carried SGI1-I or SGI1-K, indicating that the SGI suppresses transfer of the plasmid. In addition, pRMH760 was rapidly lost from both E. coli and S. enterica strains that also carried SGI1-I, SGI1-F or SGI2. However, plasmid loss was not seen when the SGI1 variant was SGI1-K, which lacks two segments of the SGI1 backbone. The complete sequence of the SGI1-I and SGI1-F were determined and SGI1-K also carries two single base substitutions relative to SGI1-I. The IncA (A/C 1 ) plasmid RA1 was also shown to mobilize SGI2-A and though there are significant differences between the backbones of IncA and IncC plasmids, RA1 was also rapidly lost when SGI2-A was present in the same cell. We conclude that there are multiple interactions, both cooperative and antagonistic, between an IncA or IncC plasmid and the SGI1 and SGI2 family genomic islands. Copyright © 2016 Elsevier B.V.

    In the present study, we use all-sky energy-resolved energetic neutral atom (ENA) maps obtained by the Ion and Neutral CAmera (INCA) instrument on board Cassini that correspond to the time period from 2003 to 2009, in four discrete energy passbands (∼5.4 to ∼55 keV), to investigate the geometrical characteristics of the belt (a broad band of emission in the sky). The heliospheric ENA emissions are mapped in three different coordinate systems (ecliptic, Galactic, and interstellar magnetic field (ISMF)), and spectral analyses are performed to further examine the belt's possible energy dependence. Our conclusions are summarized as follows: (1) the high flux ENA belt identified in the energy range of 8-42 keV is moderately well organized in Galactic coordinates, as the ENA minima appear in the vicinity of the north and south Galactic poles; (2) using minimization criteria ( B · R ∼ 0), the deviation of the ENA emissions from the equator is effectively minimized in a rotated frame, which we interpret as ISMF, where its north pole points toward 190° ecliptic longitude and 15° ecliptic latitude; (3) ENA spectra show a power-law form in energy that can be fitted with a single function presenting higher spectral slopes in the belt region and lower outside (3.4 < γ < 4.4); (4) the spectra are almost indistinguishable between the tail and the nose regions, i.e., no noticeable asymmetry is observed; (5) the consistency of the ENA distributions as a function of latitude among the different INCA channels indicates that the morphology of the belt (peak, width, and structure) is nearly energy independent from 8 keV to 30 keV (minor deviations start to appear at >35 keV); and (6) in the low count rate regions, the long-term ENA count rate profiles do not match the measured cosmic ray profiles, indicating that even the minimum ENA emissions detected by INCA are foreground ENAs.

    The Low Energy Charged Particle (LECP) in situ measurements from V1 and V2 have revealed a reservoir of ions and electrons that constitute the heliosheath (HS) after crossing the termination shock (TS) 35deg north and 32deg south of the ecliptic plane at 94 and 84 astronomical units (1 AU= 1.5 x10 ^{8} km), respectively. The outer Heliosphere boundary, the Heliopause (HP), has now been determined in the direction of V1 to be at ˜122 AU. The in situ measurements by each Voyager were placed in a global context by remote sensing images using ENA obtained with the Ion and Neutral Camera (INCA) onboard Cassini orbiting Saturn. The ENA images have revealed a 5.2-55 keV hydrogen (H) ENA region (Belt) that loops through the celestial sphere and contributes to balancing the pressure of the interstellar magnetic field (ISMF). Here we address one of the remaining and most important questions: Where do the 5-55 keV ENAs that INCA measures come from? We analyzed INCA all-sky maps from 2003 to 2015 and compare the solar cycle (SC) variation of the ENAs in both the nose (upstream) and anti-nose (downstream) directions with the intensities of > 30 keV ions (source of ENA through charge exchange-CE with H) measured in-situ by V1 and V2, in overlapping energy bands ˜30-55 keV. ENA intensities decrease during the declining phase of SC23 by ˜x3 from 2003 to 2011 but recover through 2014 (SC24); similarly, V1 and V2 ion intensities also decrease and then recover through 2014. The similarity of time profiles of remotely sensed ENA and locally measured ions are consistent with (a) ENA originating in the HS, and (b) the global HS responding promptly (within ˜1-1.5 years) to outward-propagating solar wind changes throughout the SC. Further, recovery of the Belt during SC24 precedes asymmetrically from south to north in the general direction of the nose. This may be related to the non-symmetric evolution of solar coronal holes during SC recovery.

Of the six common food flavonoid classes, flavonols are distributed ubiquitously among different plant foods whereas appreciable amounts of isoflavones are found in leguminous plant-based foods. Flavonoids have shown promising health promoting effects in human cell culture, experimental animal and human clinical studies. They have shown antioxidant, hypocholesterolemic, anti-inflammatory effects as well as ability to modulate cell signaling and gene expression related disease development. Low bioavailability of flavonoids has been a concern as it can limit or even hinder their health effects. Therefore, attempts to improve their bioavailability in order to improve the efficacy of flavonoids are being studied. Further investigations on bioavailability are warranted as it is a determining factor for flavonoid biological activity. PMID:23989753

    Suicide continues to be one of the biggest killers in the world, with suicide rates varying between 8.1 and 58.3/100,000 population for different parts of India. Andhra Pradesh, the fourth largest state in India, is responsible for more than 11% of these. Unfortunately, most suicides are under-reported and there is scant data on attempted suicides. This study aimed to comprehensively study the characteristics of attempted suicides in Andhra Pradesh and using the primary data, make secondary projections for the forthcoming years. Using Patient Care Record (PCR) forms of all emergencies serviced by 108, the first comprehensive emergency service in India, an analysis of all cases was done to detect possible suicides during the period January-December 2007. A follow up 48 hours later was then done to confirm status and diagnosis. A total of 1007 cases were recorded as confirmed suicides. Hanging and insecticide poisoning (72%) were the most common methods used. Males preferred hanging and insecticide poisoning while females preferred self-immolation and hanging as common methods. Self-immolation and insecticide poisoning had the highest mortality (41.6%). Estimates of attempted suicides for the year 2008 revealed a mean of 3.2-3.8 per 1000 population for males, 3.3-3.7 per 1000 population for females and 6.4-7.6 per 1000 population combined. A serious epidemic of suicides seems to be in store in the coming years unless preventive steps in the form of policy changes are undertaken. Restricting access to poisonous substances or prescription drugs and taking into consideration the prevailing social, economic and cultural factors could help in reducing numbers. Starting tele-help services or offering brief interventions during hospital stays are other programs which may be considered.

    A water soluble storage albumin from Inca peanut (IPA) accounted for approximately 25% (w/w) of defatted seed flour weight, representing 31% of the total seed protein. IPA is a 3S storage protein composed of two glycosylated polypeptides, with estimated molecular weights (MW) of 32800 and 34800 Da, respectively. IPA has an estimated sugar content of 4.8% +/- 0.92% (n = 6). IPA is a basic protein (pI of approximately 9.4) and contains all of the essential amino acids in adequate amounts when compared to the FAO/WHO recommended pattern for a human adult. The tryptophan content of IPA is unusually high (44 mg/g of protein), whereas the phenylalanine content is low (9 mg/g of protein). IPA is a highly digestible protein in vitro.

    In the framework of nuclear waste transmutation studies, the Mini-INCA project has been initiated at Cea/DSM to determine optimal conditions for transmutation and incineration of Minor Actinides in high intensity neutron fluxes in the thermal region. Our experimental tool is based on alpha- and gamma-spectroscopy of irradiated samples and microscopic fission-chambers. It can provide both microscopic information on nuclear reactions (total and partial cross sections for neutron capture and/or fission reactions) and macroscopic information on transmutation and incineration potentials. The 232 Th, 237 Np, 241 Am, and 244 Cm transmutation chains have been explored in details, showing some discrepancies in comparison with evaluated data libraries but in overall good agreement with recent experimental data.

    Full Text Available The present article proposes a political reading of two texts that are connected to each other: the History of the Incas by Pedro Sarmiento de Gamboa and the Antiquitatum Variarum by Annio de Viterbo, a collection of spurious texts from the end of the 15th century. Doing a synthesis between the Antiquitatum and the platonic myth of Atlantis, Sarmiento argued that the Indians were descendants of Túbal lineage, the grandson of Noah and founder of the Hispanic monarchy which had come to the Indies after the Universal Flood. It is proposed that the History of the Incas as well as the Antiquitatum were part of an official current of imperial representation of the past promoted by the Catholic Kings, that was projected to Spanish and Indies chronicles during the 16th century.El presente artículo propone una lectura política de dos libros vinculados entre sí: la Historia de los Incas de Pedro Sarmiento de Gamboa y la Antiquitatum Variarum de Annio de Viterbo, una colección de textos espurios de fines del siglo XV. Haciendo una síntesis entre la Antiquitatum y el mito platónico de la Atlántida, Sarmiento argumentó que los indios descendían de la estirpe de Túbal, el nieto de Noé y fundador de la monarquía hispánica, que había llegado a las Indias después del Diluvio Universal. Se propone que tanto la Historia de los Incas como la Antiquitatum formaron parte de una corriente oficial de representación del pasado de corte imperial promovida por los Reyes Católicos, que se proyectó a las crónicas hispanas y a las de Indias en el transcurso del siglo XVI.

    Catchment-scale water quality models are increasingly popular tools for exploring the potential effects of land management, land use change and climate change on water quality. However, the dynamic, catchment-scale nutrient models in common usage are complex, with many uncertain parameters requiring calibration, limiting their usability and robustness. A key question is whether this complexity is justified. To explore this, we developed a parsimonious phosphorus model, SimplyP, incorporating a rainfall-runoff model and a biogeochemical model able to simulate daily streamflow, suspended sediment, and particulate and dissolved phosphorus dynamics. The model's complexity was compared to one popular nutrient model, INCA-P, and the performance of the two models was compared in a small rural catchment in northeast Scotland. For three land use classes, less than six SimplyP parameters must be determined through calibration, the rest may be based on measurements, while INCA-P has around 40 unmeasurable parameters. Despite substantially simpler process-representation, SimplyP performed comparably to INCA-P in both calibration and validation and produced similar long-term projections in response to changes in land management. Results support the hypothesis that INCA-P is overly complex for the study catchment. We hope our findings will help prompt wider model comparison exercises, as well as debate among the water quality modeling community as to whether today's models are fit for purpose. Simpler models such as SimplyP have the potential to be useful management and research tools, building blocks for future model development (prototype code is freely available), or benchmarks against which more complex models could be evaluated.

    Patients with liver cirrhosis have a highly elevated risk of developing bacterial infections that significantly decrease survival rates. One of the most relevant infections is spontaneous bacterial peritonitis (SBP). Recently, NOD2 germline variants were found to be potential predictors of the development of infectious complications and mortality in patients with cirrhosis. The aim of the INCA (Impact of NOD2 genotype-guided antibiotic prevention on survival in patients with liver Cirrhosis and Ascites) trial is to investigate whether survival of this genetically defined high-risk group of patients with cirrhosis defined by the presence of NOD2 variants is improved by primary antibiotic prophylaxis of SBP. The INCA trial is a double-blind, placebo-controlled clinical trial with two parallel treatment arms (arm 1: norfloxacin 400 mg once daily; arm 2: placebo once daily; 12-month treatment and observational period). Balanced randomization of 186 eligible patients with stratification for the protein content of the ascites (INCA trial is first in the field of hepatology aimed at rapidly transferring and validating information on individual genetic risk into clinical decision algorithms.

    Aerosols influence the Earth radiative budget both through their direct (scattering and absorption of solar radiation) and indirect (impacts on cloud microphysics) effects. The anthropogenic perturbation due to aerosol emissions is of the same order of magnitude than the one due to greenhouse gases, but less well known. To improve our knowledge, we need to better know aerosol spatial and temporal distributions. Indeed, aerosol modeling still suffers from large uncertainties in sources and transport, while satellite observations are incomplete (no detection in the presence of clouds, no information on the vertical distribution or on the chemical nature). Moreover, field campaigns are localized in space and time. This study aims to reduce uncertainties in aerosol distributions, developing assimilation of satellite data into a chemical transport model. The basic idea is to combine information obtained from spatial observation (optical thickness) and modeling studies (aerosol types, vertical distribution). In this study, we assimilate data from the POLDER space-borne instrument into the LMDz-INCA model. The results show the advantage of merging information from different sources. In many regions, the method reduces uncertainties on aerosol distribution (reduction of RMS error). An application of the method to the study of aerosol impact on cloud microphysics is shown.

    The long-term application of road salts has led to a rise in surface water chloride (Cl - ) concentrations. While models have been used to assess the potential future impacts of continued deicing practices, prior approaches have not incorporated changes in climate that are projected to impact hydrogeology in the 21st century. We use an INtegrated CAtchment (INCA) model to simulate Cl - concentrations in the Tioughnioga River watershed. The model was run over a baseline period (1961-1990) and climate simulations from a range of GCMs run over three 30-year intervals (2010-2039; 2040-2069; 2070-2099). Model projections suggest that Cl - concentrations in the two river branches will continue to rise for several decades, before beginning to decline around 2040-2069, with all GCM scenarios indicating reductions in snowfall and associated salt applications over the 21st century. The delay in stream response is most likely attributed to climate change and continued contribution of Cl - from aquifers. By 2100, surface water Cl - concentrations will decrease to below 1960s values. Catchments dominated by urban lands will experience a decrease in average surface water Cl - , although moderate compared to more rural catchments.

    The IBEX Mission has been collecting ENAs from the outer heliosphere for nearly eight years, or three-quarters of a solar cycle. In that time, we have observed clear evidence of the imprint of the solar cycle in the time variation in the ENA flux. The most detailed of such studies has focused on the polar ENA flux observed by IBEX-Hi, as the IBEX spacecraft attitude allows for continuous coverage of the ENA flux incident from the ecliptic poles (Reisenfeld et al. 2012, 2016). By time correlating the ENA-derived heliosheath pressure to the observed 1 AU dynamic pressure, we can estimate the distance to the ENA source region. We can further derive the thickness of the ENA-producing region (presumably the inner heliosheath) by assuming pressure balance at the termination shock (TS). This requires using the 1 AU observations to derive the dynamic pressure at the TS shock by use of a mass-loaded solar wind propagation model (Schwadron et al. 2011), and by integrating ENA observations across all energies that significantly contribute to the heliosheath pressure. This means including polar ENA observations from not only IBEX-Hi, but from IBEX-Lo and Cassini/INCA, spanning an energy range of 15 eV to 40 keV. We will present our latest polar ENA observations and estimates for the distance to the TS and the thickness of the heliosheath.

    In the present study we use all-sky energy-resolved (5-55 keV) energetic neutral atom (ENA) maps obtained by the Ion and Neutral CAmera (INCA) on board Cassini during the time period DOY 265/2003 to 268/2003, to investigate the properties of the peak-to-basin ENA emissions in the direction of the heliotail. Our conclusions can be summarized as follows: (1) a relatively smooth boundary (called t ransition region ) between the very low (basin) and high (tail) ENA emissions from the heliosheath, with a spatial width of ∼30° deg in ecl. longitude, that no theory had predicted to date, is identified in the energy range of 5-55 keV; (2) the ENA intensity gradient in this transition region is almost invariant as a function of both ecl. Latitude and energy, with an average value of ∼2.4% per degree; (3) the deduced partial plasma pressure distributions in the 5-55 keV energy range are consistent with the ENA intensity distributions in the same energy range, while the ENA intensity gradient translates to a corresponding partial pressure gradient that occurs in the transition region; and (4) this partial pressure gradient is possibly not consistent with a tail magnetic field configuration that is similar to the measured magnetic fields by the Voyagers in the nose hemisphere

    While transgenderism as a cultural phenomenon seems to be based on a collective taste for the sensational, its emergence represents a collective shift towards a new or more differentiated way of experiencing and expressing sex and gender, a movement of world soul. This paper attempts to explore that emergence from a Jungian perspective. The paper utilizes clinical examples which illustrate how dissociated aspects of the personality are seeking assimilation and expression in order to move the personality towards greater wholeness. In that sense, it attempts to understand the teleology of transgenderism on an individual and collective level. The paper is intended as a starting-off point for discussion and explores gender as fantasy, anima/animus dynamics, the psyche/soma relationship, the role of hormones/biochemistry in our experience of ourselves and what transgender people carry and suffer for our culture. © 2017, The Society of Analytical Psychology.

    Adolescent suicide attempts are disproportionally prevalent and frequently of low severity, raising questions regarding their long-term prognostic implications. In this study, we examined whether adolescent attempts were associated with impairments related to suicidality, psychopathology, and psychosocial functioning in adulthood (objective 1) and whether these impairments were better accounted for by concurrent adolescent confounders (objective 2). Eight hundred and sixteen adolescents were assessed using interviews and questionnaires at four time points from adolescence to adulthood. We examined whether lifetime suicide attempts in adolescence (by T2, mean age 17) predicted adult outcomes (by T4, mean age 30) using linear and logistic regressions in unadjusted models (objective 1) and adjusting for sociodemographic background, adolescent psychopathology, and family risk factors (objective 2). In unadjusted analyses, adolescent suicide attempts predicted poorer adjustment on all outcomes, except those related to social role status. After adjustment, adolescent attempts remained predictive of axis I and II psychopathology (anxiety disorder, antisocial and borderline personality disorder symptoms), global and social adjustment, risky sex, and psychiatric treatment utilization. However, adolescent attempts no longer predicted most adult outcomes, notably suicide attempts and major depressive disorder. Secondary analyses indicated that associations did not differ by sex and attempt characteristics (intent, lethality, recurrence). Adolescent suicide attempters are at high risk of protracted and wide-ranging impairments, regardless of the characteristics of their attempt. Although attempts specifically predict (and possibly influence) several outcomes, results suggest that most impairments reflect the confounding contributions of other individual and family problems or vulnerabilites in adolescent attempters. © 2014 Wiley Periodicals, Inc.

The most common cause for premature death in schizophrenia is suicide. There are very few Indian studies on suicide in persons suffering from schizophrenia. OBJECTIVES The objectives were to study the frequency of suicide attempt in schizophrenia to compare and study the clinical and sociodemographic profile of suicide attempters and non-attempters in schizophrenia and to analyse and study the various risk factors of suicide attempts in persons suffering from schizophrenia. METHODS A sample of 100 consecutive patients attending review OPD of a government tertiary care hospital in Chennai were selected. Those who had a diagnosis of schizophrenia were screened for past suicide attempts. They were divided into two groups as suicide attempters and non-attempters and analysed using the SAPS (Scale for Assessment of Positive Symptoms, SANS (Scale for Assessment of Negative Symptoms, Calgary depression scale, and Beck’s suicide intent scale. RESULTS People suffering from schizophrenia are at a high risk for making suicidal attempts (27% especially when the illness is acute and severe in early stages when accompanied by depressive symptoms. Demographic profile such as age, sex, education, occupation, socio-economic status, marital status, and family type were not significantly related to suicide attempts. Family history of suicide was a significant factor in patients with suicide attempts. Majority of the attempts were of medium-to-high intent, hanging being the commonest method, and were attributed to most commonly delusions and depressive symptoms.

This is further supported by New World camelid fibers attached to her plaits, typical Inca-type skull deformation and the type of Wormian bone at her occiput. Despite an only small transverse wound of the supraorbital region computed tomography scans show an almost complete destruction of face and frontal skull bones with terrace-like margins, but without evidence for tissue reaction.

    Background: Suicides, attempted suicides and different form of suicidal behaviors are on the rise in most part of the world. It is generally assumed that official suicidal rate are underestimated from the true rate by 20-100 % due to prevailing socio-cultural issues, religious attitude, stigma attached, and legal process involved. Attempted suicides occur 8-20 times more frequently than complete suicide. Statistics on attempted suicide or deliberate self harm are not usually available officia...

    2012-01-01

    Background It has been suggested that shame may be an important feature in suicidal behaviors. The disposition to react with shame, “shame-proneness”, has previously not been investigated in groups of attempted suicide patients. We examined shame-proneness in two groups of attempted suicide patients, one group of non-suicidal patients and one group of healthy controls. We hypothesized that the attempted suicide patients would be more shame-prone than non-suicidal patients and healthy controls. Methods The Test of Self-Conscious Affect (TOSCA), which is the most used measure of shame-proneness, was completed by attempted suicide patients (n = 175: 105 women and 3 men with borderline personality disorder [BPD], 45 women and 22 men without BPD), non-suicidal psychiatric patients (n = 162), and healthy controls (n = 161). The participants were convenience samples, with patients from three clinical research projects and healthy controls from a fourth research project. The relationship between shame-proneness and attempted suicide was studied with group comparisons and multiple regressions. Men and women were analyzed separately. Results Women were generally more shame-prone than men of the same participant group. Female suicide attempters with BPD were significantly more shame-prone than both female suicide attempters without BPD and female non-suicidal patients and controls. Male suicide attempters without BPD were significantly less shame-prone than non-suicidal male patients. In multiple regressions, shame-proneness was predicted by level of depression and BPD (but not by attempted suicide) in female patients, and level of depression and non-suicidality in male patients. Conclusions Contrary to our hypothesis and related previous research, there was no general relationship between shame-proneness and attempted suicide. Shame-proneness was differentially related to attempted suicide in different groups of suicide attempters, with significantly high

    Teen suicide is the third leading cause of death for 15-24year olds. A clear understanding of what the experience of being suicidal means to adolescents living the phenomenon has not been clearly addressed in the literature. The aim of this research was to generate a comprehensive interpretation of the experiences of six adolescents who visited the ED following a suicide attempt, using hermeneutic phenomenological methodology. Participants ranged in age from 15 to 19years old, and all had been hospitalized for their attempt. Two patterns emerged: attempting as communicating and attempting as transforming. Underlying themes are described in detail. The findings have implications for nursing practice including how to assess and intervene with adolescent suicide attempters. Copyright © 2015 Elsevier Inc.

  7. Mathematics across cultures the history of non-Western mathematics

    CERN Document Server

    2000-01-01

    Mathematics Across Cultures: A History of Non-Western Mathematics consists of essays dealing with the mathematical knowledge and beliefs of cultures outside the United States and Europe. In addition to articles surveying Islamic, Chinese, Native American, Aboriginal Australian, Inca, Egyptian, and African mathematics, among others, the book includes essays on Rationality, Logic and Mathematics, and the transfer of knowledge from East to West. The essays address the connections between science and culture and relate the mathematical practices to the cultures which produced them. Each essay is well illustrated and contains an extensive bibliography. Because the geographic range is global, the book fills a gap in both the history of science and in cultural studies. It should find a place on the bookshelves of advanced undergraduate students, graduate students, and scholars, as well as in libraries serving those groups.

  8. Modeling the terrestrial N processes in a small mountain catchment through INCA-N: A case study in Taiwan.

    Riverine dissolved inorganic nitrogen (DIN) is an important indicator of trophic status of aquatic ecosystems. High riverine DIN export in Taiwan, ~3800kg-Nkm -2 yr -1 , which is ~18 times higher than the global average, urges the need of thorough understanding of N cycling processes. We applied INCA-N (Integrated Nitrogen Catchment Model) to simulate riverine DIN export and infer terrestrial N processes using weekly rainwater and streamwater samples collected at the Fushan Experimental Forest (FEF) of northern Taiwan. Results showed that the modeled discharge and nitrate export are in good agreement with observations, suggesting the validity of our application. Based on our modeling, the three main N removal processes, in the order of descending importance, were plant uptake, riverine N transport and denitrification at FEF. The high plant uptake rate, 4920kg-Nkm -2 yr -1 , should have led to accumulation of large biomass but biomass at FEF was relatively small compared to other tropical forests, likely due to periodic typhoon disruptions. The low nitrate concentration but high DIN export highlights the importance of hydrological control over DIN export, particularly during typhoons. The denitrification rate, 750kg-Nkm -2 yr -1 , at FEF was also low compared to other tropical forest ecosystems, likely resulting from quick water drainage through the coarse-loamy top soils. The high DIN export to atmospheric deposition ratio, 0.45, suggests that FEF may be in advanced stages of N excess. This simulation provides useful insights for establishing monitoring programs and improves our understanding N cycling in subtropical watersheds. Copyright © 2017 Elsevier B.V. All rights reserved.

    2018-03-07

    The present study analyzes the water quality characteristics of the Ramganga (a major tributary of the Ganga river) using long-term (1991-2009) monthly data and applies the Integrated Catchment Model of Nitrogen (INCA-N) and Phosphorus (INCA-P) to the catchment. The models were calibrated and validated using discharge (1993-2011), phosphate (1993-2010) and nitrate (2007-2010) concentrations. The model results were assessed based on Pearson's correlation, Nash-Sutcliffe and Percentage bias statistics along with a visual inspection of the outputs. The seasonal variation study shows high nutrient concentrations in the pre-monsoon season compared to the other seasons. High nutrient concentrations in the low flows period pose a serious threat to aquatic life of the river although the concentrations are lowered during high flows because of the dilution effect. The hydrological model is satisfactorily calibrated with R 2 and NS values ranging between 0.6-0.8 and 0.4-0.8, respectively. INCA-N and INCA-P successfully capture the seasonal trend of nutrient concentrations with R 2 >0.5 and PBIAS within ±17% for the monthly averages. Although, high concentrations are detected in the low flows period, around 50% of the nutrient load is transported by the monsoonal high flows. The downstream catchments are characterized by high nutrient transport through high flows where additional nutrient supply from industries and agricultural practices also prevail. The seasonal nitrate (R 2 : 0.88-0.94) and phosphate (R 2 : 0.62-0.95) loads in the catchment are calculated using model results and ratio estimator load calculation technique. On average, around 548tonnes of phosphorus (as phosphate) and 77,051tonnes of nitrogen (as nitrate) are estimated to be exported annually from the Ramganga River to the Ganga. Overall, the model has been able to successfully reproduce the catchment dynamics in terms of seasonal variation and broad-scale spatial variability of nutrient fluxes in the

    The basic goal of the proposed Interstellar Mapping and Acceleration Probe (IMAP) is detailed scientific understanding of the Heliosheath (HS) and beyond, a region of space explored in situ by Voyager 1 (V1) since 2004, Voyager 2 (V2) since 2007, and remotely via energetic neutral atoms (ENA) by the Cassini/INCA (5.2-55 keV) since 2003 and IBEX (0.3-6 keV) since 2009. The partial overlap in energies (28 5 keV, the rest residing below that range, resulting in a beta (particle/magnetic pressure) always > 1, typically >10. (2) Based on the ENA-derived hot ion pressures, the interstellar magnetic field (ISMF) was predicted to be more than twice that expected in the literature i.e. similar to what was measured by V1 after crossing the heliopause (B 0.5 nT). (3) The width of the HS in the direction of V1 is 30 AU (predicted by INCA before the V1 HP crossing), but is thought to be larger (40-70 AU) in the southern ecliptic where V2, now 30 AU into the HS, currently travels. We address here the key question of the source of 5-55 keV ENAs that INCA measures. The analysis of INCA all-sky maps from 2003 to 2014 show that the decrease and recovery of ENA in the global heliosphere during this period (declining phase of SC23 and rise of SC24) is similar to that of the ions at V1/V2, consistent with the HS ions being the source of ENA. The close correspondence between ENA and ion spectra (despite the 140 AU distance between V1 and V2) as well as the similarity of ENA spectra over the nose and anti-nose directions, together with the recent V1 measurement of a BISMF 0.5nT, suggest that the global distributions of >5 keV ions in the heliosheath resembles a diamagnetic bubble with no significant tail-like feature (the alternative Parker 1961 model), also consistent with some recent MHD simulations and models.

    Full Text Available A lo largo de la Colonia se va construyendo una memoria de la historia de los pueblos andinos que considera al Imperio incaico como su principal referente y a la figura del Inca1 como su símbolo natural. La narración de los hechos de la historia incaica, en especial aquellos relativos a la conquista española, generaron el mito de la muerte del Inca2, a la cual habrán contribuido colonizados y colonizadores. Durante el siglo XVIII serán numerosas las representaciones teatral-musicales de estos hechos.

    Posttraumatic stress disorder and major depressive disorder are well-established risk factors for suicidal behavior. This study compared depressed suicide attempters with and without comorbid posttraumatic stress disorder with respect to additional diagnoses, global functioning, depressive symptoms, substance abuse, history of traumatic exposure, and suicidal behavior. Adult patients consecutively admitted to a general hospital after a suicide attempt were interviewed and assessed for DSM-IV diagnosis and clinical correlates. Sixty-four patients (71%) were diagnosed with depression; of them, 21 patients (32%) had posttraumatic stress disorder. There were no group differences in social adjustment, depressive symptoms, or suicidal intent. However, the group with comorbid depression and posttraumatic stress disorder had more additional Axis I diagnoses, a higher degree of childhood trauma exposure, and more often reported previous suicide attempts, non-suicidal self-harm, and vengeful suicidal motives. These findings underline the clinical importance of diagnosis and treatment of posttraumatic stress disorder in suicide attempters.

    We evaluated whether the prevalence of lifetime suicide attempts/completions was higher in women with a lifetime history of an eating disorder than in women with no eating disorder and assessed whether eating disorder features, comorbid psychopathology, and personality characteristics were associated with suicide attempts in women with anorexia nervosa, restricting subtype (ANR), anorexia nervosa, binge-purge subtype (ANBP), lifetime history of both anorexia nervosa and bulimia nervosa (ANBN), bulimia nervosa (BN), binge eating disorder (BED), and purging disorder (PD). Participants were part of the Swedish Twin study of Adults: Genes and Environment (N = 13,035) cohort. Lifetime suicide attempts were identified using diagnoses from the Swedish National Patient and Cause of Death Registers. General linear models were applied to evaluate whether eating disorder category (ANR, ANBP, ANBN, BN, BED, PD, or no eating disorder [no ED]) was associated with suicide attempts and to identify factors associated with suicide attempts. Relative to women with no ED, lifetime suicide attempts were significantly more common in women with all types of eating disorder. None of the eating disorder features or personality variables was significantly associated with suicide attempts. In the ANBP and ANBN groups, the prevalence of comorbid psychiatric conditions was higher in individuals with than without a lifetime suicide attempt. The odds of suicide were highest in presentations that included purging behavior (ANBN, ANBN, BN, and PD), but were elevated in all eating disorders. To improve outcomes and decrease mortality, it is critical to be vigilant for suicide and identify indices for those who are at greatest risk.

    suicide attempt with aluminum phosphide fumigant has high mortality conditions. The aim was to investigate the frequency of aluminum phosphide consumption in suicide attempt. a retrospective case series study at the Hospital General de Tejupilco during the period 2009-2011 was done. Thirty-two patients had attempted suicide; we included 18 whose suicide attempt was with aluminum phosphide. The risk of rescue according Weisman's scale was measured. from 18 suicidal patients, 83 % were women (n = 15); the average age was 17.7 ± 4.4 years; 89 % (n = 16) were = 23 years old; and 89 % (n = 16) had depression. The motive for the suicide attempt was being abandoned by a partner in 56 % (10). Mortality rate was 78 % (n = 14) and death ocurred in 4 ± 2 hours. aluminum phosphide is the most commonly used toxic substance in rural areas for suicide attempts. Among suicides, the most common cause among women was abandonment by her partner and was also related to depression and emotional security to dying.

    Importance The U.S. Army suicide attempt rate increased sharply during the wars in Afghanistan and Iraq. Comprehensive research on this important health outcome has been hampered by a lack of integration among Army administrative data systems. Objective To identify risk factors for Regular Army suicide attempts during the years 2004–2009 using data from the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS). Design, Setting, and Participants There were 9,791 medically documented suicide attempts among Regular Army soldiers during the study period. Individual-level person-month records from Army and Department of Defense administrative data systems were analyzed to identify socio-demographic, service-related, and mental health risk factors distinguishing suicide attempt cases from an equal-probability control sample of 183,826 person-months. Main Outcome and Measures Suicide attempts were identified using Department of Defense Suicide Event Report records and ICD-9 E95x diagnostic codes. Predictor variables were constructed from Army personnel and medical records. Results Enlisted soldiers accounted for 98.6% of all suicide attempts, with an overall rate of 377/100,000 person-years, versus 27.9/100,000 person-years for officers. Significant multivariate predictors among enlisted soldiers included socio-demographic characteristics (female gender, older age at Army entry, younger current age, low education, non-hispanic white), short length of service, never or previously deployed, and the presence and recency of mental health diagnoses. Among officers, only socio-demographic characteristics (female gender, older age at Army entry, younger current age, and low education) and the presence and recency of mental health diagnoses were significant. Conclusions and Relevance Results represent the most comprehensive accounting of U.S. Army suicide attempts to date and reveal unique risk profiles for enlisted soldiers and officers, and highlighting the

    2014-01-01

    Suicide is a major cause of mortality for patients with eating disorders (ED), especially for patients with anorexia nervosa. Attempted suicide is also relatively common in patients with anorexia or bulimia nervosa. This study aimed at examining associations between attempted suicide and trait- and state-dependent characteristics in a large clinical population of ED patients. The sample consisted of 1,436 in- and outpatients of the Centre for Eating Disorders of the Ghent University Hospital. Measures of ED symptoms, psychopathology, and personality traits were compared between ED patients with and ED patients without a history of attempted suicide. A history of attempted suicide was found in 11.8% of the ED patients and lifetime suicidal ideation was reported by 43.3%. Multivariate analyses showed that a history of attempted suicide was associated with higher scores on depression, purging symptomatology, early-developed cognitive schemes (impaired autonomy and increased inhibition), and social insecurity. These findings support the increased risk of suicidal behavior in ED. The presence of particular personality traits, of cognitive schemes, and of purging and depressive symptoms should increase vigilance for suicidal behavior.

    Information compilation is a novel research topic which aims to compile various information intelligently, and to make it easy to comprehend/access. The information compilation is emphasized by two characteristics. The first one is a cross-modalitiness achieved by cooperation between non-linguistic information and linguistic information, and the second one is a continuousness in supporting all aspects of information utilization. To foster researches related to the information compilation, we conducted three attempts: installation of a reference model on information compilation, distribution of annotated corpus and a visualization platform as boundary objects, and deployment of an evaluation workshop. The paper describes current efforts of the attempts.

    A better understanding of risk factors for suicide in general population is crucial for the design of suicide prevention programs. Our objective was to identify personal and family risk factors in suicide attempters. Case-control design. We searched in patients with an acute intoxication, those subjects with and intoxication attributable to suicide attempt. These patients were matched with controls by gender and the date of intoxication. We use a structured questionnaire to identify personal characteristics, family features and network support. Odds ratio (OR) and 95 % confidence interval were obtained. 25 cases and 25 controls were evaluated. The risk factors associated with suicide attempt adjusted by age, were being a student and smoking habits. Family violence background showed OR = 3.8 (IC 95 % = 1.1-13), family disintegration a OR = 8.5 (IC 95 % = 2.1-35), critical events background OR = 8.8 (IC 95 % = 2.1-36), poor self-esteem OR = 8.2 (IC 95 % 2-35), depression OR = 22 (IC 95 % = 3-190), anxiety OR = 9 (IC 95 % = 2-47), family dysfunction OR = 25 (IC 95 % = 4-151). The principal risk factor for suicide attempt was family dysfunction and psychological traits.

    Attempted suicide in children and adolescents is a disturbing and painful issue for patients, their families and physicians. Current medical literature provides little information about minors who attempt suicide, possibly because there is under-reporting of this condition as a diagnosis, or maybe because it is sometimes considered as a way for the child to draw attention. To present the experience of the Department of Psychiatry (Universidad Nacional de Colombia) at the Hospital Infantil de La Misericordia, from 2003 to 2013. An observational retrospective study was conducted by reviewing 213 cases of children and adolescents treated for attempted suicide at the Hospital Infantil de La Misericordia from January 1, 2003 to October 31, 2013, and who received hospital or outpatient care in Child Psychiatry. A review was performed of the diagnosis, the number of suicide attempts, the peak months of consultation for this reason, and the methods selected, as well as a detailed description of the group of patients under 12 years old, and those managed with outpatient follow-up. The average patient is a female teenager who becomes intoxicated with drugs. Most often, patients do not return to outpatient follow-up. Those with follow-up have multiple psychopathologies and a high level of suffering. The most common methods, other than poisoning by drugs, are hanging and jumping from heights. Patients under 12 years old generally have their first attempt by drug poisoning. There is a predominance of anxiety disorder and depression, with a strong association with cognitive dysfunction, as a vulnerability factor. Copyright © 2013 Asociación Colombiana de Psiquiatría.

    Mental health of soldiers is adversely affected by the death and injury of other unit members, but whether risk of suicide attempt is influenced by previous suicide attempts in a soldier's unit is unknown. To examine whether a soldier's risk of suicide attempt is influenced by previous suicide attempts in that soldier's unit. Using administrative data from the Army Study to Assess Risk and Resilience in Servicemembers (STARRS), this study identified person-month records for all active-duty, regular US Army, enlisted soldiers who attempted suicide from January 1, 2004, through December 31, 2009 (n = 9650), and an equal-probability sample of control person-months (n = 153 528). Data analysis was performed from August 8, 2016, to April 10, 2017. Logistic regression analyses examined the number of past-year suicide attempts in a soldier's unit as a predictor of subsequent suicide attempt, controlling for sociodemographic features, service-related characteristics, prior mental health diagnosis, and other unit variables, including suicide-, combat-, and unintentional injury-related unit deaths. The study also examined whether the influence of previous unit suicide attempts varied by military occupational specialty (MOS) and unit size. Of the final analytic sample of 9512 enlisted soldiers who attempted suicide and 151 526 control person-months, most were male (86.4%), 29 years or younger (68.4%), younger than 21 years when entering the army (62.2%), white (59.8%), high school educated (76.6%), and currently married (54.8%). In adjusted models, soldiers were more likely to attempt suicide if 1 or more suicide attempts occurred in their unit during the past year (odds ratios [ORs], 1.4-2.3; P < .001), with odds increasing as the number of unit attempts increased. The odds of suicide attempt among soldiers in a unit with 5 or more past-year attempts was more than twice that of soldiers in a unit with no previous attempts (OR, 2.3; 95% CI, 2.1-2.6). The

    The radiative forcing of cirrus clouds is influenced by microphysical (e.g., ice crystal number concentration and size distribution) and macroscopic properties. Currently it is still unclear how the formation of cirrus clouds and their microphysical properties are influenced by anthropogenic emissions. In this work, we use airborne in-situ observations to compare cirrus cloud properties between polluted and pristine regions. Our dataset includes: the NSF HIAPER Pole-to-Pole Observations (HIPPO) Global campaign (2009-2011), the EU Interhemispheric Differences In Cirrus Properties from Anthropogenic Emissions (INCA) campaign (2000) and the NASA Airborne Tropical Tropopause Experiment (ATTREX) campaign (2014). The combined dataset include observations of both extratropical (HIPPO and INCA) and tropical (ATTREX) cirrus, over the Northern and Southern Hemispheres. We use the in-situ measured carbon monoxide (CO) mixing ratio as a pollution indicator, and compare ice microphysical properties (i.e., ice crystal number concentration (Nc) and number-weighted mean diameter (Dc)) between air masses with higher and lower CO. All analyses are restricted to T ≤ -40°C. By analyzing ice crystals (Fast-2DC, 87.5-1600 µm) in HIPPO, we found that Dc decreases with increasing CO concentration at multiple constant pressure levels. In addition, analysis of INCA data shows that Nc and extinction of small ice particles (FSSP 3-20 µm) increases with increasing CO. Particles < 87.5 µm in Fast-2DC data are not considered due to uncertainty in sample volume, and the FSSP measurements are subject to possible shattering. We further analyze the ice crystals (SPEC FCDP, 1-50 µm) in the tropical tropopause layer in ATTREX. At -70°C to -90°C, we found that the average Nc (Dc) increases (decreases) at higher CO. Overall, our results suggest that extratropical and tropical cirrus are likely to have more numerous small ice particles, when sampled in the more polluted background. Back

    To develop a risk index of suicide attempts in the last 12 months among people with suicide ideation. Cross-sectional study. Data came from the National Addictions Survey 2008. The risk index was made up by age, marital status, religion, occupation, area of the country in which they live, immigrant to the United States, alcohol and drug consumption, depression symptoms, behavioral problems and a history of sexual abuse. We found a monotonic relationship between the increase in risk factors and the existence of a plan and the risk, with an odds ratio over 2.07 up to 152.19. The area under the curve is quite high, with a value of 0.844, very close to 1. The use of this index may help prevent patients from further developing their suicide ideation process and may prevent a suicide attempt of uncertain consequences, including death.

    The semi-distributed, dynamic INCA-N model was used to simulate the behaviour of dissolved inorganic nitrogen (DIN) in two Finnish research catchments. Parameter sensitivity and model structural uncertainty were analysed using generalized sensitivity analysis. The Mustajoki catchment is a forested upstream catchment, while the Savijoki catchment represents intensively cultivated lowlands. In general, there were more influential parameters in Savijoki than Mustajoki. Model results were sensitive to N-transformation rates, vegetation dynamics, and soil and river hydrology. Values of the sensitive parameters were based on long-term measurements covering both warm and cold years. The highest measured DIN concentrations fell between minimum and maximum values estimated during the uncertainty analysis. The lowest measured concentrations fell outside these bounds, suggesting that some retention processes may be missing from the current model structure. The lowest concentrations occurred mainly during low flow periods; so effects on total loads were small. (orig.)

    INCA-Indoor, a new indoor air quality (IAQ) model, has been developed to simulate the concentrations of volatile organic compounds (VOC) and oxidants considering indoor air specific processes such as: emission, ventilation, surface interactions (sorption, deposition, uptake). Based on the detailed version of SAPRC-07 chemical mechanism, INCA-Indoor is able to analyze the contribution of the production and loss pathways of key chemical species (VOCs, oxidants, radical species). The potential of this model has been tested through three complementary analyses: a comparison with the most detailed IAQ model found in the literature, focusing on oxidant species; realistic scenarios covering a large range of conditions, involving variable OH sources like HONO; and the investigation of alkenes ozonolysis under a large range of indoor conditions that can increase OH and HO2 concentrations. Simulations have been run changing nitrous acid (HONO) concentrations, NOx levels, photolysis rates and ventilation rates, showing that HONO can be the main source of indoor OH. Cleaning events using products containing D-limonene have been simulated at different periods of the day. These scenarios show that HOX concentrations can significantly increase in specific conditions. An assessment of the impact of indoor chemistry on the potential formation of secondary species such as formaldehyde (HCHO) and acetaldehyde (CH3CHO) has been carried out under various room configuration scenarios and a study of the HOx budget for different realistic scenarios has been performed. It has been shown that, under the simulation conditions, formaldehyde can be affected by oxidant concentrations via chemical production which can account for more than 10% of the total production, representing 6.5 ppb/h. On the other hand, acetaldehyde production is affected more by oxidation processes. When the photolysis rates are high, chemical processes are responsible for about 50% of the total production of

    Suicides, attempted suicides and different form of suicidal behaviors are on the rise in most part of the world. It is generally assumed that official suicidal rate are underestimated from the true rate by 20-100 % due to prevailing socio-cultural issues, religious attitude, stigma attached, and legal process involved. Attempted suicides occur 8-20 times more frequently than complete suicide. Statistics on attempted suicide or deliberate self harm are not usually available officially. All the cases of attempted suicide who were admitted and referred for psychiatric evaluation and management to a rural medical college of central India during a period of one Year (April 13-March-14), following initial recovery they were evaluated on a semi-structured performa on socio demographic profile, mode of attempt and reason for attempt. Data collected was analyzed using suitable statistical methods. Total 68 cases were evaluated during the study period. 43% of the cases were involved in farming. Among 85% of the study population pesticide consumption was the common mode of attempt, which is easily available among the agrarian community of rural India. Interpersonal conflict in the family due to indebtedness, financial loss due to crop failure was the commonest reason for attempt. Though there is reduced reporting in the incidents of suicide cases in media from this region, still quite a number of people attempt suicide due to financial constraint from crop failure, ongoing indebtedness, and poor socioeconomic condition culminating into poor mental health among the rural agrarian community of central Maharashtra.

    Conclusion: Our study confirms some previous Western reports that adolescents with depressive disorders commonly manifest suicide attempts. There are, however, some cultural differences in risk factors. School-related problems play an important role in Taiwan among the adolescent suicides, and prior suicide attempts predict future suicidal behavior. Enhancing school-based screening for adolescents with suicide risk and transferring them to psychiatric professionals for intervention is important. We should focus suicide prevention resources mainly on the adolescent population with psychiatric illness, prior suicide attempts, and with high risk factors.

    Many scientists agree that various difficulties arise when one tries to build up a worldview incorporating some form of realism which can accommodate our knowledge about natural phenomena. We investigate whether quantum mechanics (Q.M.), in the standard interpretation or in some of its more widely known and accepted variants, can be taken as a basis for such a program. Having pointed out that, in our opinion, this is not the case, we present an attempt to overcome the difficulties by accepting stochastic and nonlinear modifications of the evolution equation of the theory.

    2015-02-01

    Although there is clear evidence that low levels of positive future thinking (anticipation of positive experiences in the future) and hopelessness are associated with suicide risk, the relationship between the content of positive future thinking and suicidal behavior has yet to be investigated. This is the first study to determine whether the positive future thinking-suicide attempt relationship varies as a function of the content of the thoughts and whether positive future thinking predicts suicide attempts over time. A total of 388 patients hospitalized following a suicide attempt completed a range of clinical and psychological measures (depression, hopelessness, suicidal ideation, suicidal intent and positive future thinking). Fifteen months later, a nationally linked database was used to determine who had been hospitalized again after a suicide attempt. During follow-up, 25.6% of linked participants were readmitted to hospital following a suicide attempt. In univariate logistic regression analyses, previous suicide attempts, suicidal ideation, hopelessness, and depression-as well as low levels of achievement, low levels of financial positive future thoughts, and high levels of intrapersonal (thoughts about the individual and no one else) positive future thoughts predicted repeat suicide attempts. However, only previous suicide attempts, suicidal ideation, and high levels of intrapersonal positive future thinking were significant predictors in multivariate analyses. Positive future thinking has predictive utility over time; however, the content of the thinking affects the direction and strength of the positive future thinking-suicidal behavior relationship. Future research is required to understand the mechanisms that link high levels of intrapersonal positive future thinking to suicide risk and how intrapersonal thinking should be targeted in treatment interventions.

    Full Text Available Objective. Trichloroacetic acid (TCAA, or trichloroethanoic acid, is a chemical analogue of acetic acid where three methyl group hydrogen atoms are replaced by chlorine. TCAAs are also abbreviated and referred to as TCAs, causing confusion with the psychiatric antidepressant drug class, especially among patients. TCAAs exist in dermatological treatments such as chemical peels or wart chemoablation medication. TCAA ingestion or overdose can cause gastric irritation symptoms including vomiting, diarrhea, or lassitude. This symptomatology is less severe than TCA overdose, where symptoms may include elevated body temperature, blurred vision, dilated pupils, sleepiness, confusion, seizures, rapid heart rate, and cardiac arrest. Owing to the vast difference in symptoms, the need for clinical intervention differs greatly. While overdose of either in a self-harm attempt can warrant psychiatric hospital admission, the risk of death in TCAA ingestion is far less. Case Report. A patient ingested TCAA in the form of a commercially available dermatological chemical peel as a self-harm attempt, thinking that it was a more injurious TCA. Conclusion. Awareness among physicians, particularly psychiatrists, regarding this relatively obscure chemical compound (TCAA and its use by suicidal patients mistakenly believing it to be a substance that can be significantly more lethal (TCA, is imperative.

  8. SUICIDAL ATTEMPTS AMONG YOUNG RURAL INHABITANTS

    2010-06-01

    Full Text Available In recent years changes have been noted in the motivations for acute suicidal poisonings among young people from various environments, which are due to psychosocial changes both in the urban and rural environments. Suicidal attempts are accompanied – especially in the rural environment – by low social status, difficulties with adapting to a free market economy, emotional tension within the family, at school, in the environment of young people, addiction to alcohol, drug overuse, including psychotropes. Based on clinical material concerning rural inhabitants hospitalized due to suicidal poisonings, the authors performed the analysis of attitudes, motivations and causes of acute poisonings among the young rural population. Among rural adolescents who continued school or university education the dominant causes of undertaking a suicidal attempt were: adolescent period problems, conflicts within the family, conflicts with mates, and disappointment in love. Among young adults the motivations were as follows: difficulties with finding employment in the place of residence, conflicts within the family, overuse of stimulants, and sometimes states of depression during the period of aggravation of a disease.

    2008-03-01

    Nicotine replacement therapy (NRT) doubles successful quitting, but more than half of NRT users do not comply with optimal treatment regimens. From the 2005 Colorado state tobacco survey, quit attempters who utilized NRT (N=366) were analyzed in spring 2007. Descriptive and regression analyses were used to examine reasons for discontinuing NRT, length of time on NRT, and quit intentions. The reasons for discontinuing NRT were resuming smoking (34%), side effects (17%), NRT not helping with quitting (14%), quitting smoking (10%), and cost (5%). Poverty, age, and non-Latino minority status were associated with reasons for discontinuation other than quitting smoking. Having side effects was associated with a short duration of NRT use and 95% lower odds of intending to quit in the next month. In the first population-level study examining reasons for discontinuing NRT, general-population smokers who initiate NRT use when attempting to quit are highly likely to discontinue NRT prematurely. Age and culturally-appropriate medication management interventions may increase NRT compliance and improve cessation outcomes.

    2007-06-01

    An outbreak of dermatophytosis caused by Microsporum canis occurred in tigers (Panthera tigris) at an exotic felid sanctuary in 2003. In an attempt to find an effective, practical, safe, and affordable method for controlling this epizootic, a clinical treatment trial was conducted. Nonalopecic tigers were studied to address the inapparent carrier state observed at the facility. The efficacy of three topical and environmental treatment combinations of a 2% lime sulfur solution and a peroxide-based cleaner were evaluated in nonalopecic, culture-positive tigers (n = 18) housed in four separate enclosures. Lime sulfur solution was applied topically to all of these animals. As a control, nonalopecic but culture-positive tigers (n = 6) housed in two other enclosures were not treated. Environmental treatments included lime sulfur solution (n = 1), a peroxide-based cleaner (n = 1), and no treatment (n = 2). All solutions were applied at 2-wk intervals for seven treatments. The 2% lime sulfur solution treatments were unsuccessful in resolving infections in most tigers. Lime sulfur was effective in suppressing environmental fungal growth immediately posttreatment, whereas the peroxide-based cleaner was not effective. A follow-up survey of all study tigers and their enclosures was conducted 2 yr later, at which time 22 of 24 tigers (92%) had attained resolution, defined as two sequential negative hair cultures. Review of the culture results during the clinical trial and follow-up study suggests that nonalopecic dermatophytosis in tigers that are housed outdoors may not warrant aggressive individual or environmental treatment, as the infection may clear with time.

    2018-03-01

    This study aims to explore the impact of negative life events (NLEs) on attempted suicide in a Chinese cultural setting. The sample comprised 791 suicide attempters and an equal number of controls matched on age, sex, and location from selected rural counties in China. Conditional logistic regression model was used to examine the association between NLEs and suicide risk. The impact of NLEs on attempted suicide was further examined using regression-based method to explore its mediation effect. The types of NLEs that were most likely to precede a suicide attempt in rural sample included the events in marriage/love, family/home, and friend/relationship. Rural women were more likely to experience more interpersonal conflicts than rural men. Approximately 75.6% of suicide attempters had experienced at least one NLE, and NLEs were strongly associated with attempted suicide. Total effect (0.676), direct effect (0.501), and the total indirect effect (0.301) of NLEs on suicide attempts were significantly mediated by hopelessness and depression. NLEs play a crucial role in predicting suicidal attempt in rural China, and they are mediated by depression and hopelessness.

    Tattoo removal is increasingly required as the number of, particularly young, people acquiring tattoos is increasing. A 21-year-old man is reported who underwent attempted removal of large dragon tattoo utilizing a tattoo machine that injected a phenol-containing solution. At the end of the 3-h procedure, he collapsed and died. At autopsy, large areas of white skin discoloration with focal necrosis and sloughing were present overlying areas of previous tattooing. Histological examination showed collections of eosinophilic fluid with a minimal chronic inflammatory infiltrate in better preserved areas, with focal areas of dermal necrosis. Toxicology was positive for phenol in cardiac blood and liver tissue. There were no underlying organic disease or injuries present which could have caused or contributed to death. This idiosyncratic method of tattoo removal involving subcutaneous injection of phenol had resulted in death most likely from cardiotoxicity. © 2016 American Academy of Forensic Sciences.

    Because group-hunting arboreal ants spread-eagle insect prey for a long time before retrieving them, these prey can be coveted by predatory flying insects. Yet, attempting to rob these prey is risky if the ant species is also an effective predator. Here, we show that trying to rob prey from Azteca andreae workers is a fatal error as 268 out of 276 potential cleptobionts (97.1 %) were captured in turn. The ant workers hunt in a group and use the "Velcro®" principle to cling firmly to the leaves of their host tree, permitting them to capture very large prey. Exceptions were one social wasp, plus some Trigona spp. workers and flies that landed directly on the prey and were able to take off immediately when attacked. We conclude that in this situation, previously captured prey attract potential cleptobionts that are captured in turn in most of the cases.

  16. Potassium permanganate ingestion as a suicide attempt

    2012-01-01

    Full Text Available Potassium permanganate is a highly corrosive, water-soluble oxidizing antiseptic. A 68- year-old female patient was admitted to our Emergency Department after ingestion of 3 tablets of 250 mg potassium permanganate as a suicide attempt. The physical exam revealed brown stained lesions in the oropharynx. Emergency endoscopy was performed by the gastroenterologist after the third hour of ingestion. Emergency endoscopy revealed multiple superficial (Grade I-II lesions on the esophagus and cardia, which were considered secondary to the caustic substance. The mainstay in the treatment of potassium permanganate is supportive and the immediate priority is to secure the airway. Emergency endoscopy is an important tool used to evaluate the location and severity of injury to the esophagus, stomach and duodenum after caustic ingestion. Patients with signs and symptoms of intentional ingestion should undergo endoscopy within 12 to 24 h to define the extent of the disease.

  17. Suicide attempts in schizophrenic patients: clinical variables.

    Schizophrenia is associated with a significant risk of suicide: 40-50% of schizophrenic patients report suicidal ideation at some point in their lives, and 4-13% eventually commit suicide. In order to be able to predict and prevent suicide in schizophrenic patients, it is necessary to investigate and characterise suicide victims who meet the criteria for psychotic disorders and risk factors. The aim of this retrospective study was to verify the associations between suicide attempts (SAs) and the demographic and clinical variables of 106 patients who met the DSM-IV-TR criteria for schizophrenia. The patients were divided into two groups on the basis of the presence/absence of lifetime suicide attempts, and their main demographic and clinical characteristics were analysed and compared. The patients with a history of SAs frequently had a duration of untreated psychosis (DUP) of ≥1 year (chi-squared test=9.984, df=1, p=0.0016). They also showed significant associations with the presence of a depressive dimension (chi-squared test=4.439, df=1, p=0.0351), hospitalisations before SAs (chi-squared test=25.515, df=1, p suicidal behaviours (chi-squared test=18.241, df=2, p=0.0001). Finally, they were more frequently prescribed typical antipsychotic agents. The severity of psychiatric symptoms indicates a high risk of suicide in schizophrenic patients. Further prospective studies of larger samples should investigate the role of early interventions and atypical antipsychotic treatment in reducing the risk. Copyright © 2013 Elsevier B.V.

    2011-01-01

    Full Text Available National surveys and other research on adolescent Latinas show that adolescent females have higher rates of suicidal ideation, planning, and attempts than other ethnic and racial minority youth. Internalizing behaviors and family conflicts are commonly associated with suicidality in research on adolescents. In the case of Latinas, we explore the connection between adolescent Hispanic cultural involvement, mother-adolescent mutuality, internalizing behaviors, and suicidality. This paper presents data from a study of 232 Latinas, some with a recent history of suicide attempts (n=122. The results show that higher adolescent Hispanic cultural involvement was associated with greater mother-daughter mutuality and thus led to reduction in the likelihood of suicide attempts. The relationship between mother-daughter mutuality and suicide attempts among Latinas is mediated by specific internalizing behaviors (withdrawn depressive. Our findings highlight the positive effect that Latino cultural values have in the relationship between Latina adolescent and their mothers and confirm the importance that internalizing behaviors and the mother-daughter relationship have for suicide attempters.

    Hypothalamic-Pituitary-Adrenal (HPA) axis dysregulation is associated with increased risk for suicidal behavior. However, it is not clear whether such dysregulation exists prior to or is a consequence of attempt. Studies also show an activation of inflammatory responses in suicidal behavior but often combine attempters with those with ideation. The sample consisted of psychiatric inpatients, aged 15-30 years, admitted for suicide attempt (SA, n=38), inpatients admitted for suicidal ideation with no prior history of attempts (SI, n=40), and healthy controls (n=37). We compared SA, SI, and controls on hair cortisol concentrations (HCC), which provides retrospective levels of cortisol and thus prior to the attempt in SA. We also compared them on the expression of genes in the HPA axis and inflammatory pathways previously implicated in suicidal behavior (GR or NR3C1, SKA2, FKBP5, IL-1β, TNF-α); plasma C-Reactive Protein (CRP); and cellular measures of glucocorticoid receptor (GR) sensitivity and stimulated production of IL-6. We found lower HCC [β=-0.55, 95% CI (-0.96, -0.13), p=0.01, ES=-0.54] in first-time SA compared to SI and controls. In addition, SA showed lower GR or NR3C1 (α isoform) mRNA [β=-5.11, 95% CI (-10.9, 0.73), p=0.09, ES=-0.46], higher CRP [β=0.94, 95% CI (-0.004, 1.9), p=0.05, ES=0.60], and higher TNF-α mRNA [β=26.4, 95% CI (7.7, 45.2), p=0.006, ES=0.73]. This is the first study to differentiate youth who attempt suicide from those with suicidal ideation on HCC and to show that low HCC precedes suicide attempt. Suicide attempters also showed a distinct biological profile on several markers in both the HPA axis and inflammatory pathways. Future longitudinal studies are needed to examine the ability of these biomarkers to predict suicidal behavior. Copyright © 2017 Elsevier Ltd. All rights reserved.

  1. On the shape and properties of the global heliosphere over the Solar Cycle with Voyager/LECP ions and Cassini/INCA ENAs

    Voyager 1 (V1) and Voyager 2 (V2) have crossed the termination shock in 2004 (V1) and 2007(V2) and traversing the Heliosheath (HS) in the upstream (nose) hemisphere, while the Ion and Neutral Camera (INCA) on Cassini enables Energetic Neutral Atom (ENA) images of the celestial sphere that place the local ion measurements by each Voyager in a global context. We present an analysis of 5.2-55 keV ENA global images of the HS and 28-53 keV in-situ ions over an 11-year period (2003-2014) that corresponds to the declining phase of solar cycle 23 (SC23) and onset of SC24. The measurements reveal a coherent decrease and recovery between ENA in the global heliosphere and in-situ ions at V1/V2 during this time period, in overlapping energy bands, establishing that the HS ions are the source of >28 keV ENA. The similarity in the overall appearance of the images throughout the INCA energy range (5.2-55 keV), reveals that the source of ENAs at 5.2 keV ENA and ion variations with the Solar Sunspot Numbers (SSN) and solar wind parameters indicates that the Heliosphere responds promptly, within 2-3 years, to outward propagating solar wind changes in both the nose and anti-nose (tail) directions following the Solar Cycle (SC) phases. A detailed latitudinal examination of the global ENA emissions, verifies that the peak intensities between the nose and anti-nose directions are nearly similar, the power law ENA spectral index (γ) is largely the same near the equator in both the nose and anti-nose directions and displays similar spatial dependence with latitude. The totality of the ENA and in situ ion observations, together with the V1 measurement of a 0.5 nT interstellar magnetic field (ISMF) and recent modeling, suggest a "bubble-shape" heliosphere, i.e with little substantial tail-like feature. These observations are essential in determining the context for the measurements anticipated by the forthcoming IMAP mission.

    Kirmes, Tomasz; Wilk, Mateusz; Chowaniec, Czesław

    This article is an attempt to complete and holistically discuss problem of euthanasia, especially its ethical and legal aspects, comparing to Polish law. The subject of euthanasia arouse interest of the society because it touches one of the most important aspects of life, which is the death. Even bigger emotions are aroused amongst physicians. They are forced to put on the line the life as biggest value on the one side and autonomy of human being on the other. It also touches the empathy for suffering. The euthanasia was divided into three forms: active euthanasia, passive euthanasia and assisted suicide. Any form of euthanasia is illegal in Poland according to both the Penal Code and Code of Medical Ethics. Range of possible penal consequences perpetrator is very wide from waiver of punishment to life imprisonment and it comes from different penal qualification of the euthanasia. Qualification of the euthanasia is based on terms of intent of perpetrator's act, request of patient, strong empathy for suffering if the patient and decision based on up-to-date medical knowledge. It is valuable to mention "do-not-resuscitate" DNR procedure, which in case of medical futility is legally accepted in Poland, but in other form may be qualified as passive euthanasia.

    Hydraulic fracturing is a technique widely used in oil, gas and unconventional reservoirs exploitation in order to enable the oil/gas to flow more easily and enhance the production. It relays on pumping into a rock a special fluid under a high pressure which creates a set of microcracks which enhance porosity of the reservoir rock. In this research, attempt of simulation of such hydrofracturing process using the Discrete Element Method approach is presented. The basic assumption of this approach is that the rock can be represented as an assembly of discrete particles cemented into a rigid sample (Potyondy 2004). An existence of voids among particles simulates then a pore system which can be filled out by fracturing fluid, numerically represented by much smaller particles. Following this microscopic point of view and its numerical representation by DEM method we present primary results of numerical analysis of hydrofracturing phenomena, using the ESyS-Particle Software. In particular, we consider what is happening in distinct vicinity of the border between rock sample and fracking particles, how cracks are creating and evolving by breaking bonds between particles, how acoustic/seismic energy is releasing and so on.

    2010-01-01

    Full Text Available Introduction. Filicide is the killing of a son or daughter by a parent. The paper examines interaction between stress and maternal psychopathology that led to the killing. Case Outline. After prolonged conflict with her ex-husband and father of her only child, the respondent committed filicide. Two years before committing filicide, after she had divorced the father of the child, the respondent attempted suicide and had to be hospitalized. On that occasion, she was diagnosed with depressive disorder, which was not treated after hospitalization. Having killed her daughter by cutting her throat, she tried to commit suicide in the same manner, by slitting her throat. During further observation, the respondent was found to suffer from acute psychotic disorder, depressive disorder and histrionic personality disorder. These disorders in interaction with stress do not provide us with an explanation for an unusual and psychopathological motivation analysis of killing the child. Conclusion. Filicide is a violent act, most frequently multifactorial in its nature. Histrionic personality disorder in mother cannot explain the filicide act. Only interactive and dynamic evaluation of this psychiatric disorder in its longitudinal, development aspects and its potentiality to enable the expression of some other psychiatric disorders, especially dissociative states, as well as the importance of prolonged and acute stress and its subjective importance for the individual can shed some more light on the mental state of the mother at the time of filicide.

    Inhalant abuse is a problem that is getting more common all around the world. The increase in prevalence of inhalant abuse escalates morbidity and mortality rates. About 22% of people using inhalant have died at their first attempt. Particularly propane, butane, or propane-butane mixture has highest mortality rates. Sudden sniffing death syndrome, cardiomyopathy, central nervous system toxicity, hematological abnormalities, kidney toxicity, and hepatocellular toxicities are the major complications of inhalant abuse. Herein we present a patient with inhalant use disorder. At the age of 19, after a stressful life event he had unsuccessfully tried to suicide by inhaling LPG (liquefied petroleum gas, a mixture of butane and propane gases). After he realized that he had hallucinations and felt better during the inhalation, he started to abuse it. He was addicted to LPG for 10 years at the time of admission. Besides being dangerous for the society security, this intense level of LPG inhalation (12 liters a day) not giving any physical harm makes this case interesting.

    2010-01-01

    Although the Nazi genocide of Jews during World War II is well known, the concurrent Nazi genocide of psychiatric patients is much less widely known. An attempt was made to estimate the number of individuals with schizophrenia who were sterilized and murdered by the Nazis and to assess the effect on the subsequent prevalence and incidence of this disease. It is estimated that between 220,000 and 269,500 individuals with schizophrenia were sterilized or killed. This total represents between 73% and 100% of all individuals with schizophrenia living in Germany between 1939 and 1945. Postwar studies of the prevalence of schizophrenia in Germany reported low rates, as expected. However, postwar rates of the incidence of schizophrenia in Germany were unexpectedly high. The Nazi genocide of psychiatric patients was the greatest criminal act in the history of psychiatry. It was also based on what are now known to be erroneous genetic theories and had no apparent long-term effect on the subsequent incidence of schizophrenia.

    Both a magnetosphere-like tail and a bubble model of the heliosphere were posited by E. N. Parker in 1961. Recently, we showed that heliosheath ions are the source of > 5.2 keV Energetic Neutral Atoms (ENA), whose images of the heliosphere exhibit a rough nose to anti-nose (tail) global symmetry that resembles a diamagnetic bubble. The comparison between energetic neutral atom (ENA) global images of the helioshphere obtained with the Ion and Neutral Camera (INCA) on board Cassini and ions measured in-situ by the Low Energy Charged Particle experiment (LECP) on board Voyager 1 and 2 (V1/V2) in overlapping energy bands over an 11-year period shows that the heliosphere responds promptly, within ∼2-3 years, to outward propagating solar wind changes in both the nose and tail directions. Here we focus on the recovery of solar cycle 24 and the response times of > 5.2 keV ENAs to show that this ∼2-3-year time delay is consistent with a “tail” of ∼80-120 AU. This preliminary rough calculation is generally consistent with lower energy ENA data (E < 6 keV, from the IBEX-Lo and IBEX-Hi) and is supported by recent modelling of the heliosphere.

    In the framework of the Mini-INCA project, dedicated to the study of Minor Actinide transmutation process in high neutron fluxes, an α- and γ-spectroscopy station has been developed and installed at the High Flux Reactor of the Laue-Langevin Institut. This set-up allows short irradiations as well as long irradiations in a high quasi-thermal neutron flux and post-irradiation spectroscopy analysis. It is well suited to measure precisely, in reference to 59 Co cross-section, neutron capture cross-sections, for all the actinides, in the thermal energy region. The first measurements using this set-up were done on 243 Am and 242 Pu isotopes. Cross-section values, at E n =0.025eV, were found to be (81.8+/-3.6)b for 243 Am and (22.5+/-1.1)b for 242 Pu. These values differ from evaluated data libraries by a factor of 9% and 17%, respectively, but are compatible with the most recent measurements, validating by the way the experimental apparatus

    2015-01-01

    Full Text Available Background: Suicides, attempted suicides and different form of suicidal behaviors are on the rise in most part of the world. It is generally assumed that official suicidal rate are underestimated from the true rate by 20-100 % due to prevailing socio-cultural issues, religious attitude, stigma attached, and legal process involved. Attempted suicides occur 8-20 times more frequently than complete suicide. Statistics on attempted suicide or deliberate self harm are not usually available officially. Materials and Methods: All the cases of attempted suicide who were admitted and referred for psychiatric evaluation and management to a rural medical college of central India during a period of one Year (April 13-March-14, following initial recovery they were evaluated on a semi-structured performa on socio demographic profile, mode of attempt and reason for attempt. Data collected was analyzed using suitable statistical methods. Results: Total 68 cases were evaluated during the study period. 43% of the cases were involved in farming. Among 85% of the study population pesticide consumption was the common mode of attempt, which is easily available among the agrarian community of rural India. Interpersonal conflict in the family due to indebtedness, financial loss due to crop failure was the commonest reason for attempt. Conclusion: Though there is reduced reporting in the incidents of suicide cases in media from this region, still quite a number of people attempt suicide due to financial constraint from crop failure, ongoing indebtedness, and poor socioeconomic condition culminating into poor mental health among the rural agrarian community of central Maharashtra.

    We examined predictors of suicide attempts in clinically depressed adolescents in Korea and gender differences in suicidal behavior. In total, 106 adolescents diagnosed with depressive disorder were recruited in South Korea. We assessed various variables that might affect suicide attempts, and used a structured interview for the diagnosis of depression and comorbidities and to evaluate suicidality. Demographic and clinical characteristics of the subjects were compared between suicide attempt and non-suicide attempt groups and we examined significant predictors of suicide attempts. Gender differences in suicidal ideation and suicidal behavior were also analyzed. Among 106 depressed participants, 50 (47.2%) adolescents were classified in the suicide attempt group. Generally, the suicide attempt and non-suicide attempt group shared similar clinical characteristics. The suicide attempt group had more females, more major depressive disorder diagnoses, more depressive episodes, and higher suicidal ideation than the non-suicide attempt group. Suicidal ideation was the only significant predictor of suicidal attempt, regardless of gender. Higher suicidal ideation frequency scores and more non-suicidal self-injurious behaviors were shown in the female suicide attempt group than the male suicide attempt group. It is recommended that suicidal ideation be assessed regularly and managed rigorously to decrease suicide risks in depressive adolescents. PMID:27776392

    Suicide attempts in kleptomania have received little investigation. This study examined rates, correlates, and predictors of suicide attempts in kleptomania. A total of 107 adolescent and adult subjects (n = 32 [29.9%] males) with DSM-IV kleptomania were assessed with standard measures of symptom severity, psychiatric comorbidity, and functional impairment. Subjects had high rates of suicide attempts (24.3%). The suicide attempt in 92.3% of those who attempted suicide was attributed specifically to kleptomania. Suicide attempts were associated with current and life-time bipolar disorder (p = .047) and lifetime personality disorder (p = .049). Individuals with kleptomania have high rates of suicide attempts. Bipolar disorder is associated with suicide attempts in individuals with kleptomania and underscores the importance of carefully assessing and monitoring suicidality in patients with kleptomania.

    People with schizophrenia have an increased risk of suicide and attempted suicide is suggested to be an important risk factor. Our objective was to assess the cumulative survival, predictive values and odds ratios of attempted suicide for suicide in a long-term cohort of patients with schizophrenia spectrum psychosis with and without previous attempted suicide. Inpatients (n=224) hospitalized with schizophrenia spectrum psychosis were followed for a mean of 25 years. All patients were followed up for causes of death. Information on suicide attempt before the end of the observation period was retrieved from medical records. Eight percent died by suicide during the follow-up. Eighteen percent of suicide attempters died by suicide. Two percent of non-attempters died by suicide. There was a strong association between previous suicide attempt and suicide in men and women. Odds ratio for attempters vs. non-attempters was 10. Suicide risk was almost three times higher in male than female suicide attempters. Previous attempted suicide is an important risk factor for suicide in both men and women with schizophrenia spectrum psychosis, particularly in male suicide attempters. The suicide risk remains high over a long period. Continuous assessment of risk factors and appropriate treatment are crucial for this patient group to prevent suicide.

    Full Text Available Relatively little research attention has been paid to sex issues in late life suicidal behaviour. The aim was to compare clinical characteristics of women and men aged 70+ who were hospitalized after a suicide attempt. We hypothesized higher depression and anxiety scores in women, and we expected to find that men would more often attribute the attempt to health problems and compromised autonomy. Participants (56 women and 47 men, mean age 80 were interviewed by a psychologist. In addition to psychiatric and somatic health assessments, participants responded to an open-ended question concerning attributions of the attempt. There were no sex differences in depression and anxiety. Forty-five percent of the men and 14% of the women had a history of substance use disorder (p = 0.02. At least one serious physical disability was noted in 60.7% of the women and 53.2% of the men (p = 0.55. Proportions attributing their attempt to somatic illness did not differ (women, 14.5% vs. men 17.4%, p = 0.79, and similar proportions attributed the attempt to reduced autonomy (women, 21.8% vs. men, 26.1%, p = 0.64. We found strikingly similar figures for depression scores, functional disability and attributions for attempting suicide in older men and women. Larger studies are needed in diverse settings as sex differences might be influenced by cultural context.

    This paper reports an attempt by the People's Republic of China to subdue its one-child policy. Widespread poverty threatened China in the mid-1970s as a result of the cultural evolution during the Mao Zedong rule, wherein the population was encouraged to produce many children. In this context the government adopted the one-child policy, which encourages late marriage among couples and allows only one child. On the other hand, there have been reports of mass sterilizations and forced abortions among rural women. Since the start of his term, President Jiang Zemin has led the country to consider amending the one-child policy and opening its doors to western journalists. Health care facilities, previously used to accommodate forced abortion and sterilization procedures, now offer maternal/child care, mammography screening, Pap smear and fertility treatments, as well as friendly lectures on one-child policy for couples during their visit. Family planning in China now involves a choice between IUD and female sterilization, with an implemented fine for those who prefer having more than one child. Despite these efforts, population experts predict a continuous rise in the Chinese population by the mid-21st century, before the population rate starts to level off and eventually decline.

    Gay men are at higher risk of suicidality. This paper describes the causes of suicide attempts as perceived by the men themselves and analyzes their impact on severity and recidivism. Mental health surveys conducted among gay men in Geneva, Switzerland, from two probability-based time-space samples in 2007 and 2011, were merged to yield a combined sample N = 762. Suicide ideation, plans, and attempts were assessed, and respondents who had ever attempted suicide answered open questions about perceived causes which were coded and categorized for analysis within the framework of cultural epidemiology. In all, 16.7% of the respondents reported a suicide attempt in their lifetime (59.5% of them with multiple attempts). At their latest attempt, over two thirds asserted intent to die, and half required medical assistance. There was a wide variety of perceived causes, with most individuals reporting multiple causes and many of the most common causes cited at both the first and most recent subsequent attempts. Social/inter-personal problems constitute the most prominent category. Problems with love/relationship and accepting one's homosexuality figure consistently among the top three causes. Whereas the former tend to be associated with weaker intent to die, the latter are associated with the strongest intent to die and reported at multiple attempts. Problems with family are among the most common perceived causes at first attempt but not at the most recent subsequent attempt. Nevertheless, they tend to be related to the strongest intent to die and the greatest medical severity of all the perceived causes. Ten percent of men attempting suicide cited depression as a cause. Although it tended to be associated with weaker intent to die, depression was most likely to be reported at multiple attempts. Respondent-driven assessment yielded both common and idiosyncratic causes of suicide and their distinct effects. Some of these perceived causes are not prominent in the current

    Little is known about suicide attempts among sex offenders. This study examines the rates of nonfatal suicide attempts among a sample (N = 3,030) of incarcerated male sex offenders. Overall, the authors found that 14% of sex offenders in the study sample had made a suicide attempt at some point in their lives. Of those, 11% had reported a suicide attempt prior to incarceration, 0.5% had made a suicide attempt while incarcerated, and 2.5% made suicide attempts both prior to and during incarceration. Sex offenders who made suicide attempts were significantly more likely than those who did not make suicide attempts to have had an abusive childhood, a history of psychiatric problems, intellectual impairment, male victims, and related victims. Suicide attempters also scored higher on actuarial risk measures than nonattempters. No differences were found in attempter status between sex offenders who committed sex offenses against children and those who committed sex offenses against adults. A history of psychiatric problems and treatment as well as childhood abuse/neglect and perpetration against male victims predicted suicide attempter status. These findings are discussed as they pertain to suicide prevention, risk assessment, and the collateral consequences of sex offender legislation.

    There is a dearth of research focusing on factors associated with suicide attempts. High rates of atypical depression have been reported in studies including unipolar and bipolar II patients. In this study, the association between suicide attempt and atypical depression, in addition to other major risk factors, was evaluated in 390 bipolar I and II out-patients. Variables were defined according to DSM-IV criteria, and assessed with a Structured Interview for DSM-IV (axis I and II). History of suicide attempt was obtained through interviews with patients and relatives. Attempters and non-attempters were compared using univariate and multivariate analysis. Attempters showed significantly higher rates of atypical depression, family history of completed suicide, depression at index episode and cluster B personality disorder. Our results highlight the relevance of atypical depression in bipolar disorder. A more accurate identification of potential attempters may contribute to the development of effective preventive treatment strategies.

Le décret n’exclut pas les nobles indigènes et l’un d’eux, D. Bartolomé Mesa Tupac Yupanqui, homme cultivé et actif, sollicite l’inscription de son cousin Don Santiago Phelipe Camilo Tupac Yupanqui dont la candidature n’est pas retenue. Ses démarches et ses dissimulations, son opiniâtreté ainsi que les faux arguments du vice-roi laissent percevoir le climat de suspicion réciproque qui régnait dans la société péruvienne encore marquée par la révolte indienne de 1780, en même temps que se révèle la véritable nature de la parole royale.

    The riverine DIN is a crucial indicator for eutrophication in river network. The riverine DIN export in Taiwan is featured by the extremely high yield, ~3800 kg-N km-2yr-1, nearly 20-fold than the global average, showing the interesting terrestrial N process yet rarely documented. In this study we collected the DIN samples in rainwater, soil water, and stream water in a mountainous forest watershed, FuShan experimental forest watershed 1 (WS1) which is a natural broadleaf forest without human activities. Based on the intensive observations, we applied the INCA-N to simulate the riverine DIN response and thus estimate the terrestrial N processes in a global synthesis. The result showed that both discharge and DIN yield were simulated well with the average Nash-Sutcliffe efficiency coefficient of 0.83 and 0.76 , respectively. Among all N processes, N uptake, mineralization, nitrification, denitrfication, and immobilization are significantly positive correlated with soil moisture (R2>0.99), which indicates that soil moisture greatly influences N cycle processes. The average rate of mineralization and nitrification in wet years are consistent with documented values, whereas the rates in dry years are lower than the observations. Despite the high nitrification rate, the secondary forest may uptake abundant N indicating the plant uptake, which responds for removing considerable nitrate, is a controlling factor in forest ecosystem. Our simulated denitrification rate falls between the documented rates of temperate forest and agricultural area, and that may be affected by the high N-deposition in Taiwan. Simulated in-stream denitrification rate is less than 10% of the rate in soil, and is a little lower than that in temperate forest. This preliminary simulation provides an insightful guide to establish the monitoring programme and improve the understanding of N cycle in subtropical.

    Lower lip squamous cell carcinoma (LLSCC) is a common malignancy of the head and neck, being mainly a consequence of a chronic exposure to ultraviolet (UV) light solar radiation. Here, we evaluated the clinicopathological profile of patients with photosensitive disorders (xeroderma pigmentosum, lupus erythematosus and albinism) that developed LLSCC. Data from patients who had a diagnosed LLSCC with a prior xeroderma pigmentosum, lupus erythematosus or albinism diagnosis that were treated at INCA from 1999 to 2012 were collected from patients medical records (n=16). The control group was composed of 68 patients with LLSCC without a medical history of photosensitivity. The clinicopathological data of this study population were collected and the association between these variables was analyzed by Fisher's exact test. Survival curves were constructed using the Kaplan-Meier method and compared by log-rank test. All statistical analyses were performed using SPSS statistics package. The mean age of patients in the photosensitive and non-photosensitive groups was 42 years and 67 years, respectively (p<0.0001). A previous history of malignant diseases was more common in the photosensitive group (p=0.001). In both groups, most tumors showed a pathological stage I/II disease. Overall and cancer-specific survival were not statistically different. However, disease-free interval showed a significant difference (p=0.01) between the photosensitive and non-photosensitive patients. Photosensitive patients presented LLSCC at earlier age but it usually was not the primary tumor in these patients. Furthermore, a more aggressive pathological behavior was not seen when compared with tumors from non-photosensitive patients. The disease-free interval was lower in photosensitive patients, as expected.

    1977-01-01

    In a survey of dental health status of ancient Southern Peru, 101 skeletal remains were studied from five cultures: Paracas, Nazca, Tiahuanaco, Ica, and Inca. The Paracas and Ica cultures exhibited more missing antemortem teeth per mandible than the other cultures. Frequency of missing one or more third molars was less than expected and not as high as reported in peoples of Mongoloid heritage. The Paracas, Ica and Nazca, "coastal" cultures had a higher caries incidence than the "inland" cultures. Whether this relates to some difference in diet or water supply remains unresolved and warrants further investigation. Moderate attrition was noted in all the Precolumbian cultures but pulpal involvement was not observed. Osteitis, noted in all the cultures, was more pronounced in the Nazca, Paracas and Ica cultures. There appeared to be a direct relationship between caries involvement and the number of missing antemortem teeth to osteitis. Calculus was heavier in the Paracas and Ica cultures. In addition, the Paracas culture exhibited a dark brown stain on the teeth which may imply some difference between the cultures in either the food, water or social habits.

    In spite of the high prevalence of suicide behaviours and the magnitude of the resultant burden, little is known about why individuals reattempt. We aim to investigate the relationships between clinical risk factors and the repetition of suicidal attempts. 1349 suicide attempters were consecutively recruited in the Emergency Room (ER) of two academic hospitals in France and Spain. Patients were extensively assessed and demographic and clinical data obtained. Data mining was used to determine the minimal number of variables that blinded the rest in relation to the number of suicide attempts. Using this set, a probabilistic graph ranking relationships with the target variable was constructed. The most common diagnoses among suicide attempters were affective disorders, followed by anxiety disorders. Risk of frequent suicide attempt was highest among middle-aged subjects, and diminished progressively with advancing age of onset at first attempt. Anxiety disorders significantly increased the risk of presenting frequent suicide attempts. Pathway analysis also indicated that frequent suicide attempts were linked to greater odds for alcohol and substance abuse disorders and more intensive treatment. Novel statistical methods found several clinical features that were associated with a history of frequent suicide attempts. The identified pathways may promote new hypothesis-driven studies of suicide attempts and preventive strategies. Copyright © 2010 Elsevier Ltd. All rights reserved.

    BACKGROUND: SSRIs are widely used in the treatment of mental illness for both children and adults. Studies have found a slightly increased risk of suicidal thoughts and suicide attempts in young people using SSRIs but SSRIs' impact on risk for suicides in youth is not well-established. AIM......: Is there indication that SSRIs might raise risk for suicide attempts in young people? METHODS: We used an observational register-based historical cohort design, a large cohort of all Danish individuals born in 1983-1989 (n = 392,458) and a propensity score approach to analyse the impact from SSRIs on risk for suicide...... attempts. Every suicide attempt and redeemed prescription of SSRIs was analysed by Cox regression. RESULTS: We found a significant overlap between redeeming a prescription on SSRIs and subsequent suicide attempt. The risk for suicide attempt was highest in the first 3 months after redeeming the first...

    Full Text Available Background: The objective was to study the sociodemographic data, psychiatric disorder, precipitating events, and mode of attempt in suicide attempted patients referred to consultation liaison psychiatric services. Settings and Design: A prospective study of 6-month duration was done in a tertiary care center in India. Materials and Methods: During the 6-month period all referrals were screened for the presence of suicide attempters in consultation liaison services. Those who fulfilled the criteria for suicide attempters were evaluated by using semistructured pro forma containing sociodemographic data, precipitating events, mode of attempt, and psychiatric diagnosis by using ICD-10. Results: The male-to-female ratio was similar. Adult age, urban background, employed, matriculation educated were more represented in this study. More than 80% of all attempters had psychiatric disorder. Majority had a precipitating event prior to suicide attempt. The most common method of attempt was by use of corrosive. Conclusions: Majority of suicide attempter patients had mental illness. Early identification and treatment of these disorders would have prevented morbidity and mortality associated with this. There is a need of proper education of relatives about keeping corrosive and other poisonous material away from patients as it was being commonest mode of attempt.

    Spirituality and religiousness are associated with a lower risk of suicide. A detailed assessment of spirituality among 88 suicide attempters hospitalized after a suicide attempt was performed. Factors associated with the recurrence of suicide attempts over 18 months were looked into. Spirituality was low among most suicide attempters in comparison with the general population. Two groups were identified: those with a high score of depression who featured "low" in spirituality and those with a more heterogeneous profile, for example, involving personality disorders, characterized by a "high" spirituality. At the follow-up, the "meaning in life" score appeared to correlate with recurrence of suicide. Clinical implications are discussed herein.

Esta investigación revela que el sitio, además de presentar evidencias de poblaciones locales, tiene colcas o qullcas para el almacenaje de productos, terrazas de pirca y caminos empedrados entre otras instalaciones. Se interpreta que Guiñayzhu es uno de los sitios de la cordillera de Chilla que refleja la expansión del incario y expresa una efectiva dominación de esta región como un enclave estratégico del imperio en su avance hacia el norte. ENGLISH: In this article, the results of research carried out in Guiñayzhu, located at the southwest of the Andes of Ecuador, are discussed. This work reveals that in addition to presenting evidence of local populations, the site has colcas or qullqas for the storage of products, terraces of pirca, and roads paved with stone, among other constructions. Guiñayzhu is interpreted as one of the sites of the Chilla mountain range that reflects the expansion of the Inca and expresses an effective domination of this region, representing a strategic enclave of the empire in its advance northward.

  8. [Factors related to suicide attempts in a Tunisian sample of patients with schizophrenia].

    The mortality rate in schizophrenia is 4.5 times higher than in the general population. Suicide is one of the main causes of premature death in this affection. Life time prevalence of this behavior ranges from 10 to 15%, which represents a risk 20 to 50 times higher than in the general population. In addition, 40 to 93% of patients who committed suicide had attempted suicide previously. Thus, assessment of correlated variables with suicide attempts is a fundamental issue for developing preventive and therapeutic strategies in suicidal behavior. To the best of our knowledge, no systematic study has yet investigated suicide attempts in an Arabic Muslim population with schizophrenia, although many authors have demonstrated cultural differences in socio-demographic and clinical variables related to suicide attempts within many geographic areas around the world. The objectives of this study were to assess the frequency and characteristics of lifetime suicide attempts in Tunisian schizophrenic outpatients and to determine the correlated socio-demographic, clinical and therapeutic variables. A total of 134 patients with a DSM-IV diagnosis of schizophrenia who attended the outpatient department of the university psychiatric hospital of Tunis were included. The main demographic and lifetime clinical variables considered were: gender, marital status, family history of psychiatric disorders and suicide attempts, age at time of recruitment, age at onset of illness, duration of untreated psychosis defined as the interval between the onset of the illness and the first antipsychotic treatment, the type and dose of current treatment, dose of antipsychotic drugs converted to chlorpromazine equivalents, extrapyramidal side effects assessed with the Simpson Angus rating scale, number of hospitalizations, comorbid substance abuse, cigarette smoking, severity of psychopathology measured with the Positive And Negative Syndrome Scale (PANSS), and history of at least one suicide attempt

    To study the specificity of hospitalized adolescent suicide attempters. Among a national sample of students (n = 11,718, mean age = 16.6 years) studied in 1999, 9.2% (n = 1078) made at least one suicide attempt during their life (SA); 21.9% (n = 234) of them were hospitalized (HSA). We identified the risk factors (family, school, behavioral and psychological) of SA and HSA by comparing (by gender) a) suicide attempters to non-suicide attempters and b) hospitalized suicide attempters to non-hospitalized suicide attempters. Both for girls and boys, the risk factors for SA varied. However, certain risk factors, particularly depressive mood, low self-esteem and poor parent-child relationships, were not associated with hospitalization. Hospitalized suicide attempters had more personal and social problems. But there is an important difference according to gender: in boys, hospitalization is related to physical fighting (OR = 2.2) and offences (OR = 3.4), in girls to running away (OR = 1.7), consumption of illegal drugs other than cannabis (OR = 2.0), having a living standard outside average (OR = 2.0) and going to a private school (OR = 1.7). Suicide attempters with problem behavior are more at risk of being hospitalized than others. However, the difference between hospitalized and non-hospitalized subjects was smaller than expected.

    OBJECTIVE: We asked whether adoption status represented a risk of suicide attempt for adopted and nonadopted offspring living in the United States. We also examined whether factors known to be associated with suicidal behavior would mediate the relationship between adoption status and suicide attempt. METHODS: Participants were drawn from the Sibling Interaction and Behavior Study, which included 692 adopted and 540 nonadopted offspring and was conducted at the University of Minnesota from 1998 to 2008. Adoptees were systematically ascertained from records of 3 large Minnesota adoption agencies; nonadoptees were ascertained from Minnesota birth records. Outcome measures were attempted suicide, reported by parent or offspring, and factors known to be associated with suicidal behavior including psychiatric disorder symptoms, personality traits, family environment, and academic disengagement. RESULTS: The odds of a reported suicide attempt were ∼4 times greater in adoptees compared with nonadoptees (odds ratio: 4.23). After adjustment for factors associated with suicidal behavior, the odds of reporting a suicide attempt were reduced but remained significantly elevated (odds ratio: 3.70). CONCLUSIONS: The odds for reported suicide attempt are elevated in individuals who are adopted relative to those who are not adopted. The relationship between adoption status and suicide attempt is partially mediated by factors known to be associated with suicidal behavior. Continued study of the risk of suicide attempt in adopted offspring may inform the larger investigation of suicidality in all adolescents and young adults. PMID:24019414

  19. Young Adults Attempt Exchanges in Reproductively Relevant Currencies

    Directory of Open Access Journals (Sweden)

    Full Text Available Adults in many species exhibit exchanges in reproductively relevant currencies, where males trade resources for sexual relations with females, and females have sex with males in exchange for provisioning. These exchanges can occur outside of a long-term partnership, which itself could be considered a commitment to the accessibility of reproductive currencies provided by each partner. The current study investigated whether young adults who are not in acute need of resources intentionally attempt reproductive currency exchanges outside of dating relationships or formal committed relationships such as marriage; and whether young adults have awareness of being the target of such attempts made by others. College students (N = 475 completed a brief survey assessing their own attempts to exchange reproductively relevant currencies, as well as others' attempts to make these exchanges with them. Men were more likely to report making attempts to trade investment for sex and women were more likely to report attempted trades of sex for investment. Participants' experiences of exchange attempts initiated by other individuals mirrored these patterns. Men were more likely to report another individual trying to trade sex for their investment, and women were more likely to report another individual trying to trade investment for sex with them. The vast majority of these attempted exchanges took place outside of existing relationships, although a small portion did lead to short or long-term relationships.

    2014-01-01

    Individuals with Asperger syndrome (AS) may be at higher risk for attempting suicide compared to the general population. This study examines the issue of suicidality in adults with AS. An online survey was completed by 50 adults from across Ontario. The sample was dichotomized into individuals who had attempted suicide (n = 18) and those who had not (n = 32). We examined the relationship between predictor variables and previous attempts, and compared the services that both groups are currently receiving. Over 35% of individuals with AS reported that they had attempted suicide in the past. Individuals who attempted suicide were more likely to have a history of depression and self-reported more severe autism symptomatology. Those with and without a suicidal history did not differ in terms of the services they were currently receiving. This study looks at predictors retrospectively and cannot ascertain how long ago the attempt was made. Although efforts were made to obtain a representative sample, there is the possibility that the individuals surveyed may be more or less distressed than the general population with AS. The suicide attempt rate in our sample is much higher than the 4.6% lifetime prevalence seen in the general population. These findings highlight a need for more specialized services to help prevent future attempts and to support this vulnerable group.

    '..only a fool perseveres in error.' Cicero. Humans will break the most advanced technological devices and override safety and security systems if they are given the latitude. Within the workplace, the operator may be just one of several factors in causing accidents or making risky decisions. Other variables considered for their involvement in the negative and often catastrophic outcomes include the organizational context and culture. Many organizations have constructed and implemented safety programs to be assimilated into their culture to assure employee commitment and understanding of the importance of everyday safety. The purpose of this paper is to examine literature on organizational safety cultures and programs that attempt to combat vulnerability, risk taking behavior and decisions and identify the role of training in attempting to mitigate unsafe acts.

  11. Quit Attempt Correlates among Smokers by Race/Ethnicity

    2011-09-01

    Full Text Available Introduction: Cigarette smoking is the leading preventable cause of premature deaths in the U.S., accounting for approximately 443,000 deaths annually. Although smoking prevalence in recent decades has declined substantially among all racial/ethnic groups, disparities in smoking-related behaviors among racial/ethnic groups continue to exist. Two of the goals of Healthy People 2020 are to reduce smoking prevalence among adults to 12% or less and to increase smoking cessation attempts by adult smokers from 41% to 80%. Our study assesses whether correlates of quit attempts vary by race/ethnicity among adult (≥18 years smokers in the U.S. Understanding racial/ethnic differences in how both internal and external factors affect quit attempts is important for targeting smoking-cessation interventions to decrease tobacco-use disparities. Methods: We used 2003 Tobacco Use Supplement to the Current Population Survey (CPS data from 16,213 adults to examine whether the relationship between demographic characteristics, smoking behaviors, smoking policies and having made a quit attempt in the past year varied by race/ethnicity. Results: Hispanics and persons of multiple races were more likely to have made a quit attempt than whites. Overall, younger individuals and those with >high school education, who smoked fewer cigarettes per day and had smoked for fewer years were more likely to have made a quit attempt. Having a smoke-free home, receiving a doctor’s advice to quit, smoking menthol cigarettes and having a greater time to when you smoked your first cigarette of the day were also associated with having made a quit attempt. The relationship between these four variables and quit attempts varied by race/ethnicity; most notably receiving a doctor’s advice was not related to quit attempts among Asian American/Pacific Islanders and menthol use among whites was associated with a lower prevalence of quit attempts while black menthol users were more likely

    Rajeev Ranjan

    2014-01-01

    Full Text Available Attempted suicide is a serious problem requiring mental health interventions, but it continues to be treated as a criminal offence under the section 309 of Indian Penal Code. The article reviews the international legal perspective across various regions of the world, discusses the unintended consequences of section 309 IPC and highlights the need for decriminalization of attempted suicide in India. The Mental Health Care Bill, 2013, still under consideration in the Rajya Sabha (upper house, has proposed that attempted suicide should not be criminally prosecuted. Decriminalization of suicidal attempt will serve to cut down the undue stigma and avoid punishment in the aftermath of incident, and lead to a more accurate collection of suicide-related statistics. From a policy perspective, it will further emphasize the urgent need to develop a framework to deliver mental health services to all those who attempt suicide.

    2016-02-01

    The aim of this paper is to understand the experience of smokers in view of unsuccessful attempts to quit smoking. This study is based on social phenomenology. Between November and December of 2014, nine interviews were conducted with people that had attempted to quit smoking. The content of these interviews was analyzed and discussed based on the related literature. Unsuccessful attempts to quit smoking are related to tobacco addiction; cigarettes are seen as a support to cope with everyday stressful situations. Attempts to quit the smoking habits were based on the need of health improvement and insistence of family and friends. Smokers reported the use of habit cessation strategies learned in support groups, but they also express expectation of specialized psychological support. The study points out the need to expand the strategies of approaching smokers, and reinforcing psychological support in order to achieve success in the attempt to quit smoking.

    Full Text Available BACKGROUND Schizophrenia has been called a ‘Life-shortening disease’, because many sufferers die early than general population and suicide accounts for a significant proportion of those dying prematurely. Suicide attempts in schizophrenia has been an intriguing area of research work for mental health professionals. Indian research on suicide attempts in schizophrenia have been few. OBJECTIVES The objectives were to study the suicidal behaviour in schizophrenia, to compare and study the positive and negative symptoms, depressive symptoms, hopelessness and suicide intent in schizophrenic population with suicide attempt compared to nonattempters, along with socio-demographic parameters. METHODS A sample of 60 consecutive patients attending OPD of a Private tertiary care Hospital in Chennai were selected. Those who had a diagnosis of schizophrenia were screened for the presence of past suicide attempts. They were divided into two groups as suicide attempters and non-attempters, and analysed using the Positive and Negative Syndrome Scale (PANSS, Calgary Depression Scale for Schizophrenia (CDSS, Beck’s hopelessness scale (BHS, and Suicide intent scale (SIS. RESULTS Among the disorders schizophrenia is rated the second most common reason for suicide attempts (53.3%, especially when associated with positive symptoms, depressive features and significant hopelessness. Demographic parameters like age, sex, educational status, occupation, economic status, and marital status were not found to be significant factors linked to the suicide attempts, however family history of suicide had a significant association in schizophrenic suicide attempts. Suicidal intent severity was medium to high among most of the attempters; poisoning was the commonest method; and were found to be due to positive symptoms and depressive symptoms in the schizophrenic illness course.

    The purpose of this study was to assess the relative risk of suicide attempt and suicide in users of hormonal contraception. The authors assessed associations between hormonal contraceptive use and suicide attempt and suicide in a nationwide prospective cohort study of all women in Denmark who had no psychiatric diagnoses, antidepressant use, or hormonal contraceptive use before age 15 and who turned 15 during the study period, which extended from 1996 through 2013. Nationwide registers provided individually updated information about use of hormonal contraception, suicide attempt, suicide, and potential confounding variables. Psychiatric diagnoses or antidepressant use during the study period were considered potential mediators between hormonal contraceptive use and risk of suicide attempt. Adjusted hazard ratios for suicide attempt and suicide were estimated for users of hormonal contraception as compared with those who never used hormonal contraception. Among nearly half a million women followed on average for 8.3 years (3.9 million person-years) with a mean age of 21 years, 6,999 first suicide attempts and 71 suicides were identified. Compared with women who never used hormonal contraceptives, the relative risk among current and recent users was 1.97 (95% CI=1.85-2.10) for suicide attempt and 3.08 (95% CI=1.34-7.08) for suicide. Risk estimates for suicide attempt were 1.91 (95% CI=1.79-2.03) for oral combined products, 2.29 (95% CI=1.77-2.95) for oral progestin-only products, 2.58 (95% CI=2.06-3.22) for vaginal ring, and 3.28 (95% CI=2.08-5.16) for patch. The association between hormonal contraceptive use and a first suicide attempt peaked after 2 months of use. Use of hormonal contraception was positively associated with subsequent suicide attempt and suicide. Adolescent women experienced the highest relative risk.

Additionally, we include published data for El Salvador and Potrerillos districts (Cornejo et al., 1997; Marsh et al., 1997; Gustafson et al., 2001). The dataset includes K/Ar, Ar/Ar and U-Pb mineral ages, which have been carefully selected for quality. The area is underlain by Carboniferous-Permian granitic basement rocks, which are covered by Triassic to Early Upper Cretaceous volcanic and sedimentary successions, including both marine and continental sequences (Cornejo et al., 1993). The period studied in this paper includes extrusive and intrusive rocks of Maastrichtian to Oligocene age, which are of particular interest since they record the 'preparation' of the lithosphere prior to, during, and after the mid-Eocene Incaic deformation and associated porphyry copper event. Shortening in the early-upper Cretaceous (95-85Ma; e.g. Mpodozis and Ramos, 1989; Arevalo and Grocott, 2000) deformed large areas of northen Chile, and marked the transition from the dominance of intra-arc extension to that of shortening punctuated by periods of extension. We recognise seven tectono-magmatic periods from the uppermost Cretaceous to Oligocene, comprising a volcanic sedimentary event contemporaneous with an extensional tectonic regime in the Upper Cretaceous, associated with graben formation, followed by an important compressive event at the beginning of the Tertiary. The middle Paleocene was again dominated by voluminous volcanic activity (collapse calderas) in an extensional regime. During the lowest Eocene the magmatic activity in the area shows a gradual transition from pyroxene-bearing to amphibole-bearing lithologies

    A suicide cluster is defined as a higher number of observed cases occurring in space and/or time than would typically be expected. Previous research has largely focused on identifying clusters of suicides, while there has been comparatively limited research on clusters of suicide attempts. We sought to identify clusters of both types of behaviour, and having done that, identify the factors that distinguish suicide attempts inside a cluster from those that were outside a cluster. We used data from Western Australia from 2000 to 2011. We defined suicide attempts as admissions to hospital for deliberate self-harm and suicides as deaths due to deliberate self-harm. Using an analytic strategy that accounted for the repetition of attempted suicide within a cluster, we performed spatial-temporal analysis using Poisson discrete scan statistics to detect clusters of suicide attempts and clusters of suicides. Logistic regression was then used to compare clustered attempts with non-clustered attempts to identify risk factors for an attempt being in a cluster. We detected 350 (1%) suicide attempts occurring within seven spatial-temporal clusters and 12 (0.6%) suicides occurring within two spatial-temporal clusters. Both of the suicide clusters were located within a larger but later suicide attempt cluster. In multivariate analysis, suicide attempts by individuals who lived in areas of low socioeconomic status had higher odds of being in a cluster than those living in areas of high socioeconomic status [odds ratio (OR) = 29.1, 95% confidence interval (CI) = 6.3-135.5]. A one percentage-point increase in the proportion of people who had changed address in the last year was associated with a 60% increase in the odds of the attempt being within a cluster (OR = 1.60, 95% CI = 1.29-1.98) and a one percentage-point increase in the proportion of Indigenous people in the area was associated with a 7% increase in the suicide being within a cluster (OR = 1.07, 95% CI = 1.00-1.13).

    Full Text Available Suicide attempts in North India are generally underreported but have been considered to be rising. The number of admissions due to attempted suicide at Duncan Hospital, North Bihar, rose from 82 in 2007 to 419 in 2011.A structured interview and the WHO (World Health Organization Major (ICD-10 Depression Inventory were completed by 157 suicide-attempt survivors. Immediate relatives were also interviewed. Only 23% of patients came from India; 77% of patients came from Nepal. The highest incidence was in the age group 16-20 years. Females have higher rates in the 21-30 year age group (p=0.012, but after 30 years of age, the number of males becomes higher than the females (p=0.048; 81.5% of the respondents were below the age of 30 years.Pesticide poisoning was the major mode of attempted suicide (94.3%. Using the WHO Major (ICD-10 Depression Inventory, 28 of the participants suffered from depression (17.7%. Ninety people (56.9% admitted to previous thoughts of suicide, and nine (5.7% people had attempted suicide previously.Hindus made up 84.0% of the respondents. Almost 50% of respondents only carried out their religious rituals on an occasional basis or not at all. 70.2% had not completed education beyond primary school, and 49.7% earned less than Rs10,000 per month (US$200. Eighty percent of the participants stated conflicts with family members led to the attempted suicide. Relatives did not expect the attempted suicide in 97.4% of cases. Knowledge of the suicide of a neighbour, friends, or relative influenced 77.0% of the participants to attempt suicide.Efforts to prevent suicide attempts and deaths need to be multifaceted. Banning the most poisonous pesticides and improving poison storage in the community must be encouraged. Prevention, early intervention and treatment all are required in a suicide prevention plan. The lack of psychiatrists necessitates that other professionals and trained non-professionals be utilised in the mental health team

    In this study, we evaluated the effect of several types of childhood trauma on lifetime suicide attempt in patients with schizophrenia spectrum disorders. We interviewed 361 participants with schizophrenia. Childhood trauma was collected using the Childhood Trauma Questionnaire (CTQ). Suicidal attempts were confirmed using subjective and objective validated scales. We applied an observational study design using propensity scores to match individuals with history of childhood trauma to those without past history of trauma. We used logistic regression models to estimate the effect of each type of childhood maltreatment on suicidal attempts controlling for demographics and known suicidal risk factors. In our sample, 39.1% of the subjects had lifetime suicide attempt. After matching the two groups and controlling for demographics and clinical confounders, total trauma score and the majority of childhood maltreatment subtypes predicted suicide attempt (odds ratios ranged from 1.74 to 2.49 with p-values ranging from 0.001 to 0.02). Physical neglect was not significantly associated with suicide attempt in our sample (p=0.94). Childhood maltreatment is confirmed to be a strong independent risk factor for suicidal attempts in schizophrenia. The risk is probably aggravated by the development of depressive symptoms and feeling of hopelessness in the adult life. Early screening and modified psychosocial treatment are recommended for psychotic individuals with trauma history. Copyright © 2016 Elsevier B.V. All rights reserved.

    Suicide is a global health concern. Therefore, studying suicide behaviour and identifying the early roots of suicide are critical. To address these issues, the present study examined (i) the association between peer relationships and suicide ideation and attempts among Chinese adolescents; and (ii) whether such associations were moderated or mediated by feeling of loneliness. We hypothesized that problems in peer relationships were positively associated with suicide ideation and attempts, and that feeling of loneliness would moderate and mediate such associations. The sample included 8778 Chinese adolescents from a large survey. Measures of peer relationships, suicide ideation and attempts, and feeling of loneliness were obtained through adolescents' self-reports. Results from multivariate logistic regressions suggested that specific problems in peer relationships, such as lack of peer association and being victimized by bullying, were significantly related to suicide ideation and attempts. In addition, the moderating effects of feeling of loneliness on the association between peer relationships and suicide ideation and attempts were found. Finally, some gender effects were also found. The present study provided strong evidence that suicide ideation and attempts were serious problems among adolescents in China, to which peer relationships played an important role. Further, feeling of loneliness acted as a moderator affecting the association between peer relationships and suicide ideation and attempts. Finally, there were some gender differences that have important implications. © 2010 Blackwell Publishing Ltd.

    Objectives To compare frequencies of suicide attempt repetition in immigrants and local European populations, and the timing of repetition in these groups. Method: Data from 7 European countries, comprising 10 574 local and 3032 immigrant subjects, were taken from the World Health Organization European Multicentre Study on Suicidal Behaviour and the ensuing Monitoring Suicidal Behaviour in Europe (commonly referred to as MONSUE) project. The relation between immigrant status and repetition of suicide attempt within 12-months following first registered attempt was analyzed with binary logistic regression, controlling for sex, age, and method of attempt. Timing of repetition was controlled for sex, age, and the recommended type of aftercare. Results: Lower odds of repeating a suicide attempt were found in Eastern European (OR 0.50; 95% CI 0.41 to 0.61, P Europe stands in contrast to their markedly higher tendency to attempt suicide in general, possibly pointing to situational stress factors related to their suicidal crisis that are less persistent over time. Our findings also raise the possibility that suicide attempters and repeaters constitute only partially overlapping populations. PMID:25565687

    1. Abstract Bipolar disorder (BD) is associated with high rates of suicide attempt and completion. Substance use disorders (SUD) have been identified as potent risk factors for suicidal behavior in BD. However, little is known concerning differences between BD subtypes with regard to SUD as a risk factor for suicidal behavior. We studied previous suicidal behavior in adults with a major depressive episode in context of BD type I (BD-I; N=96) or BD type II (BD-II; N=42), with and without history of SUD. Logistic regressions assessed the association between SUD and suicide attempt history by BD type, and exploratory analyses examined the effects of other clinical characteristics on these relationships. SUD were associated with suicide attempt in BD-I but not BD-II, an effect not attributable to sample size differences. The higher suicide attempt rate associated with alcoholism in BD-I was mostly explained by higher aggression scores, and earlier age of BD onset increased the likelihood that alcohol use disorder would be associated with suicide attempt(s). The higher suicide attempt rate associated with other drug use disorders in BD-I was collectively explained by higher impulsivity, hostility, and aggression scores. The presence of both alcohol and drug use disorders increased odds of a history of suicide attempt in a multiplicative fashion: 97% of BD-I who had both comorbid drug and alcohol use disorders had made a suicide attempt. A critical next question is how to target SUD and aggressive traits for prevention of suicidal behavior in BD-I. PMID:18590916

    Mental illness and suicidal ideation are among the strongest correlates of suicidal behaviors, but few adolescents with these risk factors make a suicide attempt. Therefore, it is critical to identify factors associated with the transition from suicide ideation to attempts. The present study tested whether deficits in cognitive control in the context of suicide-relevant stimuli (ie, suicide interference) reliably differentiated adolescent ideators and attempters. Adolescents (n = 99; 71 girls) aged 13-18 years (mean = 15.53, SD = 1.34) with recent suicide ideation (n = 60) or a recent suicide attempt (n = 39) were recruited from an acute residential treatment facility between August 2012 and December 2013. We measured interference to suicide-related, negative, and positive words using the Suicide Stroop Task (SST). When stimuli were analyzed separately, suicide attempters showed greater interference for suicide (t₉₇ = 2.04, P = .044, d = 0.41) and positive (t₉₇ = 2.63, P = .010, d = 0.53) stimuli compared to suicide ideators. An additional omnibus interference (suicide, negative, positive) x group (suicide ideator, suicide attempter) analysis of variance revealed a main effect of group (F₁,₉₇ = 4.31, P = .041, ηp² = 0.04) but no interaction (P = .166), indicating that attempters showed greater interference for emotional stimuli, regardless of valence. Multiple attempters drove this effect; single attempters and ideators did not differ in SST performance (P = .608). General deficits in cognitive control in the context of emotional stimuli may be a marker of adolescent suicide risk. © Copyright 2017 Physicians Postgraduate Press, Inc.

    Objectives Fatal and non-fatal suicide attempts are far more common in opioid dependent individuals than in the general population. More research is needed to understand the specific risk factors for suicidal behaviors in this patient population, particularly outside of the U.S. and Western Europe. This study investigated the correlates of suicide attempts among Polish patients in methadone maintenance treatment and interpreted results in the context of findings from other countries. Methods The study was based on a sample of 240 individuals recruited from a methadone maintenance clinic in Poland. Participants were interviewed using standardized measures. Results Consistent with studies in other countries, sexual abuse, depression, alcohol dependence and impulsivity were associated with suicide attempt. Additionally, those patients with somatic comorbidity had an increase in odds (OR=2.6) of suicide attempt. Conclusion The results of our study suggest a potential benefit to treatment approaches that address somatic concerns of methadone maintenance patients. More research is needed to identify, assess and understand possible cultural and regional differences between opioid dependent populations to better tailor prevention strategies. PMID:26335004

    Evidence is mixed as to whether White Europeans are at a higher risk for suicide attempts or completions compared to other ethnic groups. The present analysis assessed whether risk for suicide attempt was associated with White European ethnicity in 907 subjects with schizophrenia or bipolar disorder. Subjects were diagnosed using the Structured Clinical Interview for DSM-IV, and ethnicity was determined by self-report. Subjects were recruited from psychiatric care centers in Toronto, Canada. Logistic regression correcting for clinical covariates like age, gender and diagnosis, was used in this study. We found no difference in suicide attempter status in white and non-white subjects who were diagnosed with schizophrenia and bipolar disorder. Our study does not support the evidence that White-European patients in North America are at higher risk for suicide attempt compared to non-European descent subjects. However, this result has to be replicated in larger studies in patients with these disorders.

    Suicidal behavior is considered as the result of complex cognitive and emotional processes and it is a timeless, global and multifactorial phenomenon. Periods of financial crises in the past, such as the Great Depression in the USA in 1929 and the economic crises of Asia, Russia and Argentina in the late 1990s, have been associated with impairment of mental health of the economically affected. Unemployment, job insecurity, debts, poverty and social exclusion seems to lead to higher incidence of anxiety and depressive symptoms and increased suicidality. Alcohol and substance use and the reduction of the state budget for health services reinforce the negative effects of the economic recession on mental health. The financial crisis which currently affects many European countries began in 2008 and its impact on the mental health of European citizens is in progress. Greece is probably the most affected country by the European financial crisis. The aim of this study is to investigate the potential impact of the crisis' consequences on the attempted suicide rates in the Athens population and the differentiation of suicide attempters on social, demographic and clinical-psychopathological parameters during the crisis. A retrospective study was conducted. The semi-structured records of 165 attempters who were hospitalized in the Internal Medicine Clinics of the "Sotiria" General Hospital in Athens, after attempted suicide in the years 2007 and 2011, before and during the financial crisis respectively, were studied. Among suicide attempters 95(57.6%) were suffering from mental disorders. Most often diagnoses were these of mood disorders (n=60, 63.2%). Demographic data, current psychiatric disorder, previous suicide attempt and severity of psychopathology at the time of suicide attempt were recorded for each patient. Furthermore, the severity of each suicide attempt was estimated. Suicide attempts were 70 in 2007, before the financial crisis (mean age 36.9 years, 71% women

    To analyze the number and characteristics of suicide attempts by reviewing records of the public emergency healthcare service information system. A retrospective observational study was conducted of emergency telephone calls received between January 1 2007 and December 31 2013 throughout the Andalusia region (Southern Spain). Cases were selected based on phone operator or healthcare team labeling. Data were analyzed on the characteristics of the individuals, the timing and severity of attempts, their prioritization, and their outcome. Between January 1 2007 and December 31 2013, 20.942 calls related to suicide attempts were recorded, a rate of 34.7 attempts per 100,000 inhabitants. Most cases were classified by the public emergency healthcare service (Empresa Pública de Emergencias Sanitarias, EPES) as code X84 (The International Statistical Classification of Diseases, tenth revision, ICD-10) or 305(The International Statistical Classification of Diseases, ninth revision, ICD-9). Attempts were more frequent in the 35-49-year age group and there were similar proportions of males and females. The lowest number of calls for suicide attempts were in 2007 and the highest in 2013. Calls were more frequent during the summer months, at weekends, and between 16:00 and 23:00 h. The likelihood of evacuation to the hospital emergency department was almost two-fold lower in over 65-yr-olds than in younger individuals. Significant (ƿ = 0.001) gender differences were found in call outcome and prioritization. The most influential factor for evacuation to a hospital emergency department was the code assigned by the attending healthcare team. Information obtained from extra-hospital emergency services provides valuable data on the characteristics and timing of calls related to suicide attempts, complementing information from hospital emergency departments or population surveys. There is a need to standardize the definition and recording of a suicide attempt.

    Full Text Available Objective: To characterize the profile of suicide attempts treated at an emergency department in the municipality of Arapiraca, state of Alagoas, Brazil, from 2009 to 2012. Methods: We analyzed all emergency department records containing a diagnosis of suicide attempt. Data were evaluated using Student’s t test and Pearson’s chi-square test. Significance was accepted at p<0.05. Results: We identified 2,142 cases. Suicide attempts were more frequent among women and young adults, but deaths were more frequent among men. Suicide attempts were most frequent among patients aged 10 to 39 years (81.1%. Drug intoxication (65.0% and non-drug poisoning (16.2% were significantly more prevalent than other methods of suicide. The month of April (10.6% accounted for the greatest number of cases, and July had the smallest number (5.5%. Suicide attempts were most prevalent in spring (28.3%, on Sundays (18.4% and Saturdays (16.8%, and from 12:00 p.m. to 5:59 p.m. Conclusion: Suicide prevention measures should focus on young women. Further research into the care provided to suicide attempters and better monitoring of the sale and use of medicines and poisons could be useful.

    The influence of weather on mood and mental health is commonly debated. Furthermore, studies concerning weather and suicidal behavior have given inconsistent results. Our aim was to see if daily weather changes associate with the number of suicide attempts in Finland. All suicide attempts treated in the hospitals in Helsinki, Finland, during two separate periods, 8 years apart, were included. Altogether, 3,945 suicide attempts were compared with daily weather parameters and analyzed with a Poisson regression. We found that daily atmospheric pressure correlated statistically significantly with the number of suicide attempts, and for men the correlation was negative. Taking into account the seasonal normal value during the period 1971-2000, daily temperature, global solar radiation and precipitation did not associate with the number of suicide attempts on a statistically significant level in our study. We concluded that daily atmospheric pressure may have an impact on suicidal behavior, especially on suicide attempts of men by violent methods ( P pressure and women under high atmospheric pressure. We show only statistical correlations, which leaves the exact mechanisms of interaction between weather and suicidal behavior open. However, suicidal behavior should be assessed from the point of view of weather in addition to psychiatric and social aspects.

    The heliosheath has been identified as the most probable source of ENAs that INCA detects but its variability due to solar activity throughout the solar cycle (SC) has not been resolved to date. We show all-sky, 5-55 keV ENA H maps from the year 2003 to 2014 and compare the solar cycle variation of the ENAs in both the heliospheric nose (upstream) and anti-nose (downstream) directions with the > 30 keV ions measured within the heliosheath by the Low Energy Charged Particle (LECP) detector on Voyagers 1, 2 (V1, V2) where we measure protons in overlapping energy bands ~30-55 keV. We find that a) Toward the anti-nose direction the ENA-H intensities decline during SC23, i.e. after 2003 ENA intensities decreased by ~ x2 at all energies by the end of year 2011, ~1 year after the observed minimum in solar activity; b) This ENA decrease (5.2-55 keV) during 2009-2011 is consistent with the concurrent intensity decrease of the > 30 keV ions (by a factor of 2-3) observed in situ by V1 and V2 in the heliosheath; c) Toward the nose direction, minimum intensities in both INCA ENAs and the V2 ions at E > 28 keV occur during the year 2013, with a subsequent recovery from 2014 to date (by a factor of ~2 in the > 35 keV ENA data). These quantitative correlations between the decreases of INCA ENAs (in both the heliospheric nose and anti-nose directions) and the in situ V1 and V2 ion measurements (separated by > 130 AU) during the declining phase of SC23, along with their concurrent jointly shared recoveries at the onset of SC24, imply that: 1) the 5-55 keV ENAs are produced in the heliosheath (because their transit times over 100 AU are less than a few months at energies > 40 keV), thus proving that our ENA observations can provide the ground truth for constructing comprehensive global heliosphere models; 2) the global heliosheath responds promptly (within ~1-1.5 yrs) to outward-propagating solar wind changes throughout the solar cycle.

    'Mystic fires of Tamaatea' is the title given to a section of a book entitled 'Tsunami: the underrated hazard' written by Edward Bryant and published by Cambridge University Press in 2001. In it the author links New Zealand evidence for widespread forest destruction and Maori place-names and legends with the 15th century timing of an apparent Tunguska-type meteor impact in the South Island of New Zealand, Chinese, and Japanese meteor sightings, comets, and m ega - tsunamis in Australia. This paper critically reviews the lines of evidence used, and finds no evidence, either Maori or geological, for a 15th century meteor impact in New Zealand. In the book, all Maori place-names have been incorrectly translated, the radiocarbon chronology is incorrect, and there is no consideration of the numerous potential tsunami sources that were active in New Zealand in the 15th century.

    Full Text Available Noroviruses (NoVs and Sapoviruses (SaVs are enteric caliciviruses that have been detected in multiple mammalian species, including humans. Currently, efficient cell culture systems have been established only for murine NoVs and porcine SaV Cowden strain. Establishment of an efficient in vitro cell culture system for other NoVs and SaVs remains challenging; however, human NoV (HuNoV replication in 3D cultured Caco-2 cells and a clone of Caco-2 cells, C2BBe1, human enteroids and in human B cells has been reported. In this study, we tested various cells and culture conditions to grow HuNoVs and a human SaV (HuSaV to test the possibility of the propagation in different cells and culture conditions. We also attempted to grow a bovine NoV (BoNoV in ex vivo organ cultures. We did not observe significant RNA level increases for HuSaV and BoNoV under our test conditions. HuNoV RNA levels increased to a maximum of ~600-fold in long-term Caco-2 cells that were cultured for 1-2 months in multi-well plates and inoculated with HuNoV-positive and bacteria-free human stool suspensions using serum-free medium supplemented with the bile acid, GCDCA. However, this positive result was inconsistent. Our results demonstrated that HuNoVs, BoNoV and HuSaV largely failed to grow in vitro under our test conditions. Our purpose is to share our findings with other researchers with the goal to develop efficient, reproducible simplified and cost-effective culture systems for human and animal NoVs and SaVs in the future.

    Full Text Available Purpose: The current study examines the associations between a range of risk factors and reports of suicide attempts, and attempts requiring medical care in a nationally representative study of high school students. The goal is to examine sex differences in the risk factors that are associated with suicide attempts and attempt-related injuries requiring treatment by a health-care provider. Methods: Data from the 2007 Youth Risk Behavior Survey for students in grades 9-12 were used to assess the prevalence and risk factors for suicidal behavior as well as differences in these for boys and girls. Cross-sectional multivariate logistic regression analyses were computed to determine the most important risk factors for suicide attempts and for suicide attempts requiring medical care for the sample overall and also stratified for boys and for girls. Results: Overall, 6.9% of adolescents attempted suicide (9.3% of girls versus 4.6% of boys. Girls were more likely than boys to report a suicide attempt in the past year (Adj.OR=2.89. Among girls, sadness (Adj.OR=5.74, weapon carrying (Adj.OR=1.48, dating violence (Adj.OR=1.60, forced sex (Adj.OR=1.72, and huffing glue (Adj.OR=2.04 were significantly associated with suicide attempts. Among boys, sadness (Adj.OR=10.96, weapon carrying (Adj.OR=1.66, forced sex (Adj.OR=2.60, huffing glue (OR=1.63, hard drug use (Adj.OR=2.18, and sports involvement (Adj.OR=1.52 were significantly associated with suicide attempts. Conclusions: These findings demonstrate similarities and differences in terms of the modifiable risk factors that increase risk for suicide attempts among boys and girls. In terms of the differences between boys and girls, hard drug use and sports involvement may be important factors for suicide prevention strategies that are directed specifically towards boys, while dating violence victimization may be an important risk factor to address for girls. Overall, these findings can help guide prevention

    Low plasma total testosterone (T) levels may influence the sense of well-being and produce depressive symptomatology, increasing the risk of suicide. In a previous study, we reported reduced serum T levels in male psychiatric patients after a suicide attempt. The reduction was more pronounced in subjects who used violent attempt methods, and we discussed the possible influence of stress of hospitalization, serious medical condition and treatment. In order to minimize the influence of such factors, we compared in this study the levels of plasma sex hormones of 15 psychiatric patients (10 suffering from schizophrenia and 5 from depression) who had attempted suicide by jumping with those of a group of 18 male subjects who were hospitalized after accidentally falling from a high height. Compared with a healthy control group of 40 males, both accident and attempt groups had lower T levels. The attempt group showed a trend toward lower T levels compared with levels in the accident group. In the accident group, luteinizing hormone (LH) levels were elevated compared with levels in healthy controls, indicating a normal function of the hypothalamic-pituitary-gonadal (HPG) axis. This was not the case for the attempt group, where low T levels were not accompanied by increases in LH. Cortisol and prolactin were similarly elevated in both patient groups, but were not related to the low T levels. The results indicate that male psychiatric patients who attempt suicide by violent methods may have low total plasma T levels, possibly due to a dysfunction of the HPG axis at the hypothalamic-pituitary level. Monitoring HPG axis function in future studies could prove to be a predictor of suicide at least for male psychiatric attempters, and could lead to preventive strategies.

    Background Adolescent depression and suicide are pressing public health concerns, and identifying key differences among suicide ideators and attempters is critical. The goal of the current study is to test whether depressed adolescent suicide attempters report greater anhedonia severity and exhibit aberrant effort-cost computations in the face of uncertainty. Methods Depressed adolescents (n = 101) ages 13–19 years were administered structured clinical interviews to assess current mental health disorders and a history of suicidality (suicide ideators = 55, suicide attempters = 46). Then, participants completed self-report instruments assessing symptoms of suicidal ideation, depression, anhedonia, and anxiety as well as a computerized effort-cost computation task. Results Compared with depressed adolescent suicide ideators, attempters report greater anhedonia severity, even after concurrently controlling for symptoms of suicidal ideation, depression, and anxiety. Additionally, when completing the effort-cost computation task, suicide attempters are less likely to pursue the difficult, high value option when outcomes are uncertain. Follow-up, trial-level analyses of effort-cost computations suggest that receipt of reward does not influence future decision-making among suicide attempters, however, suicide ideators exhibit a win-stay approach when receiving rewards on previous trials. Limitations Findings should be considered in light of limitations including a modest sample size, which limits generalizability, and the cross-sectional design. Conclusions Depressed adolescent suicide attempters are characterized by greater anhedonia severity, which may impair the ability to integrate previous rewarding experiences to inform future decisions. Taken together, this may generate a feeling of powerlessness that contributes to increased suicidality and a needless loss of life. PMID:26233323

    Suicide rates are high in old age, and the contribution of cognitive risk factors remains poorly understood. Suicide may be viewed as an outcome of an altered decision process. The authors hypothesized that impairment in reward/punishment-based learning, a component of affective decision making, is associated with attempted suicide in late-life depression. They expected that suicide attempters would discount past reward/punishment history, focusing excessively on the most recent rewards and punishments. The authors further hypothesized that this impairment could be dissociated from executive abilities, such as forward planning. The authors assessed reward/punishment-based learning using the probabilistic reversal learning task in 65 individuals age 60 and older: suicide attempters, suicide ideators, nonsuicidal depressed elderly, and nondepressed comparison subjects. The authors used a reinforcement learning computational model to decompose reward/punishment processing over time. The Stockings of Cambridge test served as a control measure of executive function. Suicide attempters but not suicide ideators showed impaired probabilistic reversal learning compared to both nonsuicidal depressed elderly and nondepressed comparison subjects, after controlling for effects of education, global cognitive function, and substance use. Model-based analyses revealed that suicide attempters discounted previous history to a higher degree relative to comparison subjects, basing their choice largely on reward/punishment received on the last trial. Groups did not differ in their performance on the Stockings of Cambridge test. Older suicide attempters display impaired reward/punishment-based learning. The authors propose a hypothesis that older suicide attempters make overly present-focused decisions, ignoring past experiences. Modification of this "myopia for the past" may have therapeutic potential.

    Full Text Available Background: Suicide is a tragic and serious but preventable public health problem all over the world including Bangladesh. Committing suicide has become a burning issue and mortality rate increases especially in young females. Psychiatric evaluation is needed in suicide attempted patients for better management plan to reduce such unnatural mortality, as well as the impairment related to suicidal thought and psychiatric disorders. Objectives: To assess the psychiatric disorders and conditions that needed sufficient clinical attention among the suicide attempters who needed ICU intervention. Methods: This cross-sectional study was carried out in an Intensive Care Unit (ICU of a private hospital of Dhaka City from July 2008 to December 2008. Total forty four subjects of attempted suicide were included in the study and psychiatric diagnosis was made by using Diagnostic and Statistical Manual of Mental Disorders (DSM-IV by psychiatrists after initial physical problems subsided. Results: The most common psychiatric diagnosis was Major Depressive Disorder. Female suffered more and among them attention-seeking behaviors were frequent. Thirty-four patients (77.3% had previous history of psychiatric disorder. Chemicals (like; organophosphorous, kerosene, harpic and other medicine overdose ingestion was the most frequently used method by the suicide attempters. Conclusion: This study may be helpful for further research regarding suicide attempters and its' association with mental problems. In primary health care setting, the physicians may get a clue to design a system for preventing, early recognition and managing suicidal ideas, thoughts and attempts. Psychiatric consultation should be made mandatory for all patients admitted following attempted suicide. DOI: 10.3329/bsmmuj.v2i2.4761 BSMMU J 2009; 2(2: 73-77

    Although there have been numerous studies of suicidality in younger populations with schizophrenia, there have been no studies focused on community-dwelling older adults with schizophrenia. This study provides data on the prevalence of suicidality and factors associated with previous suicide attempts among a mixed racial sample of older persons with schizophrenia living in New York City. The schizophrenia group consisted of 198 persons aged >or=55 years who developed schizophrenia before age 45. A community comparison group (n=113) was recruited using randomly selected block groups. Fifteen predictor variables of lifetime suicide attempts based on a risk model of suicide in schizophrenia were identified. Persons in the schizophrenia group had a significantly higher prevalence of current and lifetime "suicidality" (i.e., wants to be dead, suicidal thoughts, or suicide attempts) when compared to the community group (current: 10% versus 2%; lifetime: 56% versus 7%) as well as past suicidal attempts (30% versus 4%). Within the schizophrenia group, in logistic regression analysis, 2 variables were significantly associated with lifetime suicidal attempts: current syndromal depression and higher scores on the Traumatic and Victimization Scale. The data confirmed that in later life, persons with schizophrenia continue to have a higher prevalence of suicidality than their age peers in the community. Our findings underscore the importance of monitoring for suicidality in this age group. The relative paucity of risk factors means that practitioners can more easily focus their therapeutic efforts on at-risk individuals. Copyright (c) 2010 Elsevier B.V. All rights reserved.

    Guided by the biopsychosocial framework and empirical evidence, this study examined protective and risk factors of older adults' suicidal thoughts and attempts during the previous month, 12 months, and 5 years. The data used in this study were extracted from the Sample Survey on Aged Population in Urban/Rural China conducted in 2006, which included 15,957 older adults from mainland China. Multiple penalized logistic regressions were used to conduct the analyses. During the previous month, 12 months, and 5 years, 5.1‰, 10.0‰, and 17.7‰ of older adults indicated that they thought about suicide, whereas 2.2‰, 3.5‰, and 6.3‰ reported suicidal attempts, respectively. Older adults' age, financial strain, functional limitations, depression, children's filial piety, social network, loneliness, and urban residence were significantly related to suicidal thoughts during the different time periods. In addition, older adults' religious affiliation, depression, loneliness, and urban residence were significantly related to suicidal attempts during the different time periods. Older adults' suicidal thoughts and attempts need to be assessed by mental health care professionals and primary care doctors. Programs addressing these important protective and risk factors may help reduce older adults' suicidal thoughts and attempts.

    Personality features have been correlated with suicidal behaviors in recent decades. Given its neurobiological background, Cloninger's model of personality, the Temperament and Character Inventory (TCI), may help to identify the maternal and paternal personality dimensions associated with adolescent suicide attempts. The present study is the first that specifically compares the temperament and character profiles of both mothers and fathers of the adolescent suicide attempters with a control group, by considering the influence of demographic and clinical factors. The study group comprised 117 parents of 71 adolescent suicide attempters and 119 parents of 71 age- and gender-matched adolescents without a suicide attempt included as a control group. The TCI and Brief Symptom Inventory (BSI) were applied to the parents in both groups. Logistic regression analysis, which was performed to adjust confounding factors, demonstrated significantly higher scores for harm avoidance among the mothers and lower scores of self-directedness among the fathers of the adolescent suicide attempters. New psychotherapeutic modalities considering the high-risk parental personality traits would be beneficial to support parent-adolescent relationships and may have a preventative effect on adolescent suicide.

    2014-04-01

    Full Text Available Introduction: Suicide, a complex and universal human phenomenon, is a major public health problem. This study reviewed the literature about the major risk factors associated with suicide attempts by poisoning. Methods: An integrative review of the literature was performed in databases (LILACS, PubMed and MEDLINE to search for studies published between 2003 and 2013, using the following keywords: suicide, attempted; poisoning; risk factors. Inclusion criteria were: original study with abstract, sample of adults, and attempted suicide by poisoning in at least 50% of the study population. Results: Two hundred and nineteen studies were retrieved and read by two independent examiners, and 22 were included in the study. The main risk factors for suicide attempts by poisoning were female sex, age 15-40 years, single status, little education, unemployment, drug or alcohol abuse or addiction, psychiatric disorder and psychiatric treatment using antidepressants. Conclusion: Further prospective studies should be conducted to confirm these risk factors or identify others, and their findings should contribute to planning measures to prevent suicide attempts.

    The relationship between subjective quality of life (QOL) and suicide attempts in patients with schizophrenia has been understudied. The current study tested the hypothesis that QOL is negatively associated with a history of suicidality of patients with schizophrenia. QOL, as measured by the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q), was investigated in 227 inpatients with DSM-IV diagnosis of schizophrenia with and without a lifetime history of suicide attempts. The statistical analysis included analysis of variance (ANOVA), t tests, and analysis of covariance (ANCOVA). The patients who had attempted suicide multiple times were less satisfied with regard to a larger number of life domains than the nonattempters and the single attempters. The differences in QOL remained significant after adjusting for psychiatric history and current psychopathology variables, e.g., age of onset of the disorder, number and length of hospitalizations, and positive, negative, and depressive symptoms. Dissatisfaction with QOL in general and with reference to four specific domains was associated with repeated suicide attempts. Clinicians should include QOL in the evaluation of patients with schizophrenia that are suspected to be suicidal.

    To assess the prevalence of, and demographic and smoking behaviour correlates of, attempting to purchase cigarettes via the internet among adolescent current smokers. A representative sample of 17 181 10th and 12th grade California students completed a written questionnaire on tobacco related attitudes and behaviour during the 1999-2000 school year. Logistic regression analyses were used to determine the variables associated with attempting to purchase cigarettes on the internet. Among youth under 18 years of age who were current smokers (n = 1689), 2.2% (95% confidence interval 1.5% to 2.9%) reported attempting to purchase cigarettes on the internet. Attempted internet purchases were more likely among younger respondents, males, frequent smokers, and respondents reporting lower perceived availability of tobacco products from retail and social sources. Few adolescent smokers in California surveyed during the 1999-2000 school year had attempted to obtain cigarettes from the internet. As internet access increases, future studies should examine whether internet cigarette vendors sell to minors and whether adolescents are purchasing cigarettes on the internet.

    This study examined the 2013 New Mexico Youth Risk and Resiliency Survey (NM-YRRS) to determine whether cultural connectedness and positive relationships with adults protected against suicide attempts among American Indian and Alaska Native (AI/AN) youth and whether these relationships differed by gender. The sample included 2,794 AI/AN students in grades 9 to 12 who answered the question about past-year suicide attempts. Protective factor variables tested included relationships with adults at home, school, and the community. The language spoken at home was used as a proxy measure for cultural connectedness. Positive relationships with adults were negatively associated with the prevalence of past-year suicide attempts in bivariate analysis. However, language spoken at home was not associated with the prevalence of suicide attempts. Multivariate analysis showed that among girls, relationships with adults at home, at school, and in the community were independently associated with lower suicide-attempt prevalence. Among boys, only relationships with adults at home showed such an association. These results have important implications for the direction of future research about protective factors associated with AI/AN youth suicide risk as well as in the design of suicide intervention and prevention programs.

    The relationship between suicides and suicide attempts and two biological measures, platelet monoamine oxidase levels (MAO) and average evoked response (AER) augmenting was examined in 79 off-medication psychiatric patients and in 68 college student volunteers chosen from the upper and lower deciles of MAO activity levels. In the patient sample, male individuals with low MAO and AER augmenting, a pattern previously associated with bipolar affective disorders, showed a significantly increased incidence of suicide attempts in comparison with either non-augmenting low MAO or high MAO patients. Within the normal volunteer group, all male low MAO probands with a family history of suicide or suicide attempts were AER augmenters themselves. Four completed suicides were found among relatives of low MAO probands whereas no high MAO proband had a relative who committed suicide. These findings suggest that the combination of low platelet MAO activity and AER augmenting may be associated with a possible genetic vulnerability to psychiatric disorders. (author)

    Epidemiological and clinical studies have found a significant association between smoking and suicidal behaviour. 334 outpatients with DSM-IV diagnosis of unipolar major depression, bipolar (I+II) disorder, schizophrenia, schizoaffective disorder and pure panic disorder were interviewed regarding to their smoking habits and previous suicide attempts. With the exception of panic disorder patients, the rate of prior suicide attempt(s) was much higher among current and lifetime smokers than among never smokers in all diagnostic groups, but the difference was statistically significant only for lifetime smoker unipolar depressives and for current and lifetime smoker schizophrenics. Age, social class and alcohol/caffeine consumption was not controlled and dependent vs nondependent smokers were not distinguished. The findings support previous results on the strong relationship between smoking and suicidal behaviour in psychiatric (particularly major depressive and schizophrenic) patients.

  3. Migration, distress and cultural identity.

    When people migrate from one nation or culture to another they carry their knowledge and expressions of distress with them. On settling down in the new culture, their cultural identity is likely to change and that encourages a degree of belonging; they also attempt to settle down by either assimilation or biculturalism. In this paper, various hypotheses explaining the act of migration and its relationship with mental distress are described. A new hypothesis is proposed suggesting that when sociocentric individuals from sociocentric cultures migrate to egocentric societies they may feel more alienated. In order to assess and manage migrants, the clinicians need to be aware of the pathways into migration.

    The heritable component to attempted and completed suicide is partly related to psychiatric disorders and also partly independent of them. While attempted suicide linkage regions have been identified on 2p11–12 and 6q25–26, there are likely many more such loci, the discovery of which will require a much higher resolution approach, such as the genome-wide association study (GWAS). With this in mind, we conducted an attempted suicide GWAS that compared the single nucleotide polymorphism (SNP) genotypes of 1,201 bipolar (BP) subjects with a history of suicide attempts to the genotypes of 1,497 BP subjects without a history of suicide attempts. 2,507 SNPs with evidence for association at p<0.001 were identified. These associated SNPs were subsequently tested for association in a large and independent BP sample set. None of these SNPs were significantly associated in the replication sample after correcting for multiple testing, but the combined analysis of the two sample sets produced an association signal on 2p25 (rs300774) at the threshold of genome-wide significance (p= 5.07 × 10−8). The associated SNPs on 2p25 fall in a large linkage disequilibrium block containing the ACP1 gene, a gene whose expression is significantly elevated in BP subjects who have completed suicide. Furthermore, the ACP1 protein is a tyrosine phosphatase that influences Wnt signaling, a pathway regulated by lithium, making ACP1 a functional candidate for involvement in the phenotype. Larger GWAS sample sets will be required to confirm the signal on 2p25 and to identify additional genetic risk factors increasing susceptibility for attempted suicide. PMID:21423239

    China has the largest population of smokers in the world, yet the quit rate is low. We used data from the 2010 Global Adult Tobacco Survey China to identify factors influencing quit attempts among male Chinese daily smokers. The study sample included 3303 male daily smokers. To determine the factors that were significantly associated with making a quit attempt, we conducted logistic regression analyses. In addition, mediation analyses were carried out to investigate how the intermediate association among demographics (age, education, urbanicity) and smoking-related variables affected making a quit attempt. An estimated 11.0% of male daily smokers tried to quit smoking in the 12 months prior to the survey. Logistic regression analysis indicated that younger age (15-24 years), being advised to quit by a health care provider (HCP) in the past 12 months, lower cigarette cost per pack, monthly or less frequent exposure to smoking at home, and awareness of the harms of tobacco use were significantly associated with making a quit attempt. Additional mediation analyses showed that having knowledge of the harm of tobacco, exposure to smoking at home, and having been advised to quit by an HCP were mediators of making a quit attempt for other independent variables. Evidence-based tobacco control measures such as conducting educational campaigns on the harms of tobacco use, establishing smoke-free policies at home, and integrating tobacco cessation advice into primary health care services can increase quit attempts and reduce smoking among male Chinese daily smokers.

    1998-06-01

    This study examined the relationship between school performance, smoking, and quitting attempts among teenagers. A logistic regression model was used to predict the probability of being a current smoker or a former smoker. Data were derived from the 1990 California Youth Tobacco Survey. Students' school performance was a key factor in predicting smoking and quitting attempts when other sociodemographic and family income factors were controlled. Developing academic or remedial classes designed to improve students' school performance may lead to a reduction in smoking rates among teenagers while simultaneously providing a human capital investment in their futures.

    To determine the specific clinical aspects of patients with suicidal behaviour by firearm and investigate the specificities of the suicide method. Suicidal behaviour represents a major public health problem throughout the world. Attempted suicide and completed suicide by firearms rates are very high both in Europe and in the United States. Preventive aspects presently preoccupy the physicians and the politicians. However, methods of suicide are understudied in Europe for the benefit of psychopathological and epidemiological aspects of suicide. Only a minority of studies enquire into the clinical aspects according to the method of suicide. Nevertheless, most of the international studies have already demonstrated the efficacy of reducing the accessibility of weapons. A retrospective study including suicide attempters by firearm hospitalized in the general hospital of Poitiers between 1992 and 2005. We included 161 patients with self-inflicted gunshot wounds, among which 88% of patients were males. Most of them did not live alone and had children. Some of them had a past history of attempted suicide, some of them using a violent method. The acting out has mostly been committed at home and the firearm used was frequently a hunting gun. Interpersonal conflicts have been mostly reported by the patient with self-inflicted gunshot wounds. The prevalence of alcoholic behaviour and major depression is very important. Personality disorders are overrepresented in the study, notably paranoiac and borderline disorders. Our sample is one of the largest compared to the other studies that often did not exceed 30 patients. Some results are contrary to those of populations of suicide attempters, whereas there are some similarities within the completed suicide population. Finally, paranoiac personality disorder is significantly associated with suicidal behaviour by firearm. Some clinical characteristics have been reported as far as suicide attempters by firearm are concerned. Actually

  11. TOURISM AND CULTURAL REVIVAL

    Directory of Open Access Journals (Sweden)

    George NICULESCU

    2009-12-01

    Full Text Available This paper examines the tourism and the cultural revival. Cultural change is a recurrent concern in tourism studies. Host societies frequently remodel their culture following the creation of a tourist resort. But, that does not necessarily imply an acculturating process, since what actually takes place is pragmatic cultural production work in response to the touristic demands that offer consolidated economic alternatives and livelihood. Culture change has been a concern in tourism anthropology studies ever since this field of research established itself, particularly concerning the changes host societies undergo. But that does not necessarily imply the phenomenon is to be analyzed exclusively under the focus of the acculturation paradigm, since researchers often come across the production of new cultural elements of a traditional character among host populations in their attempt to occupy new spaces from which to address the world. in fact, that applies to various social situations where local actors seek to display certain lifestyles and cultural traits in order to draw attention to their ethnic, regional, or national features. Therefore, the object of study no longer focuses on the gradual loss of local and cultural (or ethnic substance, but rather on the relative ethnicity triggered by and among translocal flows that may lead to the deliberate turnaround of different cultural aspects of the host populations. Based on those premises, this article deals with the investigation of a cultural change process, making use of the historic perspective that includes an analysis of the “strategies of cultural mobilization” activated by the social subjects that are constantly recreating themselves in the tourism areas.

  12. Adoption as a risk factor for attempted suicide during adolescence.

    Slap, G; Goodman, E; Huang, B

    2001-08-01

    Depression, impulsivity, and aggression during adolescence have been associated with both adoption and suicidal behavior. Studies of adopted adults suggest that impulsivity, even more than depression, may be an inherited factor that mediates suicidal behavior. However, the association between adoption and adolescent suicide attempts and the mechanisms that might explain it remain unknown. The objective of this study was to determine the following: 1) whether suicide attempts are more common among adolescents who live with adoptive parents rather than biological parents; 2) whether the association is mediated by impulsivity, and 3) whether family connectedness decreases the risk of suicide attempt regardless of adoptive or biological status. A secondary analysis of Wave I data from the National Longitudinal Study of Adolescent Health was conducted, which used a school-based, clustered sampling design to identify a nationally representative sample of 7th- to 12th-grade students, with oversampling of underrepresented groups. Of the 90 118 adolescents who completed the National Longitudinal Study of Adolescent Health in-school survey, 17 125 completed the in-home interview and had parents of identified gender who completed separate in-home questionnaire. The subset of adolescents for this study was drawn from the in-home sampling according to the following criteria: 1) adolescent living with adoptive or biological mother at the time of the interview, 2) adolescent had never been separated from mother for more than 6 months, 3) mother was in first marriage at the time of the interview, and 4) the adoptive mother had never been married to the adolescent's biological father. Of the 6577 adolescents in the final study sample, 214 (3.3%) were living with adoptive mothers and 6363 (96.7%) were living with biological mothers. Variables. The primary outcome measured was adolescent report of suicide attempt(s) in the past year. Other variables included in the analyses were

    Suicidality is more commonly reported among individuals with addictions relative to the general population, though data from Asian countries remain scarce. The medical records of 2187 Singaporean patients with drug (n=879), alcohol (n=754) or gambling (n=554) disorders entering an outpatient treatment service were examined to explore differences in suicidal ideation and lifetime attempts between substance and gambling addictions. The relationship between suicidality, co-morbidity and addiction severity were also examined. 25.0% reported thoughts of suicide in the past month, 11.8% had a suicide plan and 12.2% reported lifetime attempts. Rates of suicidal ideation (thoughts, and plan) but not lifetime attempts were significantly higher among gambling than substance use patients. Co-morbid (DSM-IV axis-1) disorders were found among 32.5%, 38% and 40% of those reporting thoughts, plan and lifetime attempts respectively. Addiction severity was higher and quality of life lower among those reporting suicidal behaviors. Logistic regression revealed co-morbidity, debt, gender (being female) and being a gambling patient as significant predictors of suicidal behaviors. The findings highlight the importance of screening for suicidality, even in the absence of co-morbidity, particularly among gambling disorder patients with debts. Suicide risk should be assessed periodically and referral to suicidal prevention interventions routinely offered to this vulnerable population. Copyright © 2014 Elsevier Ireland Ltd.

  9. [A phenomenological study of suicide attempts in elders].

    Im, Mi Young; Kim, Yun Jeong

    2011-02-01

    The purpose of this study was to examine the meaning and essence of suicide for elderly people who had previously attempted suicide as an older person. Giorgi's descriptive phenomenology was used for analysis. The researchers carried out in-depth interviews, recordings and memos individually with four elders. The elders were individuals who had attempted suicide sometime in the past 5 yr. They were interviewed from 5 to 10 times using open-ended questions and a semi-structural format. Demographic data were also collected. The meaning of suicide before a suicide attempt in older people had four core components: conflict with family, powerlessness and despair in their life with a drop in self-esteem, using internal and external resources to resolve their troubles and awareness of imminent crisis. These results of this study will increase understanding of suicide in older people by defining their subjective experience of suicide attempts and applying grounded data in the development of programs that provide concrete intervention strategies to prevent suicide in elderly people.

    2007-04-15

    Most prospective studies of HPA axis have found that non-suppressors in the dexamethasone suppression test (DST) are more likely to commit suicide during the follow-up. Attempted suicide is a strong clinical predictor of suicide. The aim of this study was to assess the predictive value of DST for suicide in a group of depressed inpatients with and without an index suicide attempt. Historical cohort of 382 psychiatric inpatients with mood disorder admitted to the department of Psychiatry at the Karolinska University Hospital between 1980 and 2000 were submitted to the DST and followed up for causes of death. During the follow-up (mean 18 years), 36 suicides (9.4%) occurred, 20 of these were non-suppressors and 16 were suppressors. There was no statistically significant difference in suicide risk between the suppressors and non-suppressors for the sample as a whole. An index suicide attempt predicted suicide. In suicide attempters with mood disorder, the non-suppressor status was significantly associated with suicide indicating that HPA axis hyperactivity is a risk factor for suicide in this group. The dexamethasone suppression test may be a useful predictor within this population.

    Full Text Available Cultural orientations of an organization can be its greatest strength, providing the basis for problem solving, cooperation, and communication. Culture, however, can also inhibit needed changes. Cultural changes typically happen slowly – but without cultural change, many other organizational changes are doomed to fail. The dominant culture of an organization is a major contributor to its success. But, of course, no organizational culture is purely one type or another. And the existence of secondary cultures can provide the basis for change. Therefore, organizations need to understand the cultural environments and values.

    Full Text Available Abstract Background Suicide is a global public health problem. Recently in the U.S., much attention has been given to preventing suicide and other premature mortality in veterans returning from Iraq and Afghanistan. A strong predictor of suicide is a past suicide attempt, and suicide attempters have multiple physical and mental comorbidities that put them at risk for additional causes of death. We examined mortality among U.S. military veterans after hospitalization for attempted suicide. Methods A retrospective cohort study was conducted with all military veterans receiving inpatient treatment during 1993-1998 at United States Veterans Affairs (VA medical facilities following a suicide attempt. Deaths occurring during 1993-2002, the most recent available year at the time, were identified through VA Beneficiary and Records Locator System data and National Death Index data. Mortality data for the general U.S. adult population were also obtained from the National Center for Health Statistics. Comparisons within the veteran cohort, between genders, and against the U.S. population were conducted with descriptive statistics and standardized mortality ratios. The actuarial method was used estimate the proportion of veterans in the cohort we expect would have survived through 2002 had they experienced the same rate of death that occurred over the study period in the U.S. population having the age and sex characteristics. Results During 1993-1998, 10,163 veterans were treated and discharged at a VA medical center after a suicide attempt (mean age = 44 years; 91% male.

    To identify factors associated with attempted suicide in the elderly. Social, psychological, and psychiatric characteristics were compared in suicide attempters (70 years and older) and a representative population sample. Emergency departments at five hospitals in western Sweden and a representative sample of the elderly population. Persons with Mini Mental State Examination (MMSE) score age 80 years). Comparison subjects matched for gender and age group (N = 408) were randomly selected among participants in our general population studies. Symptoms were rated with identical instruments in cases and comparison subjects. The examination included the MMSE and tests of short- and long-term memory, abstract thinking, aphasia, apraxia, and agnosia. Depressive symptomatology was measured using the Montgomery-Asberg Depression Rating Scale, and major and minor depressions were diagnosed according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, using symptom algorithms. Factors associated with attempted suicide included being unmarried, living alone, low education level, history of psychiatric treatment, and previous suicide attempt. There was no association with dementia. Odds ratios were increased for both major (odds ratio [OR]: 47.4, 95% confidence interval [CI]: 19.1-117.7) and minor (OR: 2.6, 95% CI: 1.5-4.7) depressions. An association was observed between perceived loneliness and attempted suicide; this relationship was independent of depression (OR: 2.8, 95% CI: 1.3-6.1). Observed associations mirrored those previously shown for completed suicide. Results may help to inform clinical decisions regarding suicide risk evaluation in this vulnerable and growing age group.

    Full Text Available Porphyrio porphyrio (Fulica porphyrio Linnaeus was reported to the South Florida Water Management District in a Water Conservation Area and in constructed wetlands in the Everglades in 2006. A rapid assessment, including casual observations and surveys of land managers, indicated a limited number of P. porphyrio (~300 birds was present, and an eradication attempt was initiated. From 2006 – 2008, more than 3100 P. porphyrio were killed by shotgun from airboats during 73 hunts, suggesting the initial population assessment was severely underestimated. After removing nearly 1500 P. porphyrio in 2008, we concluded that eradication was not possible. Failure of this eradication attempt is attributed to P. porphyrio’s affinity with dense emergent vegetation, which greatly limited shooting effectiveness. Further, the failed eradication underscores the importance of a reporting network to improve early detection and the chance to eliminate naturalized or feral populations of non‐native species.

  8. Suicide attempts among the elderly in East Asia.

    2017-05-01

    Among the one million suicide deaths worldwide each year, as many as 60% occur in Asia. The World Health Organization (WHO) found higher suicide rates among the elderly in rapidly industrialized Asian countries such as China, Hong Kong, Japan, South Korea, Malaysia, and Singapore, compared to the corresponding rates of recently industrializing Asian countries like Vietnam and Sri Lanka (WHO, 2014). As a case in point, suicide rates in South Korea have been the highest in the world since 2003 and are rising especially among older people (Hong and Knapp, 2014). Suicide attempts and older age are strong predictors of completed suicide (Szanto et al., 2002; Simon et al., 2013) and, as such, are important in guiding our efforts for suicide prevention; however, most epidemiological studies focus on completed suicides across all ages rather than understanding the reasons behind suicide attempts in older populations.

  9. Suicide attempts among children and adolescents: partial or total injury?

    2015-01-01

    Full Text Available This study sought to verify the records on file and the number of cases of attempted suicide among children and adolescents who were attended by Emergency Care health professionals in the municipality of Matozinhos, Minas Gerais, Brazil. Documentary and descriptive research was conducted, the data for which was collected by means of an investigation of Outpatient Records from 2008 to 2010. Of the 73,000 files evaluated, those dealing with cases of attempted suicide among children and adolescents between the age of 3 and 18 years were selected. It was revealed that the health professionals, particularly physicians and nurses, fail to register the cases appropriately, invalidating information about the problem and potential prevention measures. The conclusion reached was that underreporting and the discrepancy of the diagnoses which were not duly referred to the competent agencies require rethinking and reviewing medical practices, and taking a systematic and careful look to address the individual as a complex whole.

    2014-07-01

    A man in his twenties who had no previous history of violence, snorted large quantities of two substances he identified as 3-methoxyphencyclidine (3-MeO-PCP), and methylenedioxypyrovalerone (MDPV); both are recognised as novel psychoactive substances, or commonly described in the media as "legal highs". He also inhaled butane gas. He experienced vivid hallucinations and developed bizarre ideas. During this state of mind he stabbed his father multiple times and was arrested and charged with attempted murder. He had a previous history of drug induced psychosis and although he had some slight residual symptoms before he consumed the substances, these were not considered relevant to his criminal liability at the time of the offence. The hallucinations caused by the use of these substances took six weeks to completely recede. He was convicted of attempted murder and sentenced to four years in prison.

    We describe attempts to create ball lightning by directing lightning, triggered from natural thunderclouds using the rocket-and-wire technique, through a variety of materials. Some of the observed phenomena have features in common with natural ball lightning or with laboratory attempts to create it: flame-like luminosity for up to 0.5 s above salt water; constant-luminosity silicon fragments falling for about 1 s under the influence of gravity; a 0.7 m region of stationary luminosity whose bottom was 0.3 m above a stainless steel surface to which arcing had occurred; and a glow for about 0.5 s above pine tree sections.

    Increasingly strong evidence links anxiety disorders in general and panic attacks in particular to suicidality. The underlying causes and specifics of this relation, however, remain unclear. The present article sought to begin addressing this question by clarifying the association between panic symptoms and suicidality. Data were sampled from the NESARC epidemiological data set from the US and analyzed as four independently, randomly selected subsets of 1000 individuals using structural equation modeling analyses and replicating results across samples. Evidence is presented for four symptom clusters (cognitive symptoms, respiratory distress, symptoms of alpha and beta adrenergic activation) and the differential association of each with suicidal ideation and attempts. Symptoms of alpha adrenergic activation predicted prior suicide attempt whereas cognitive symptoms predicted prior suicidal ideation. These findings were independent of comorbid major depressive disorder. It is suggested that assessment of suicide risk in the community includes the presentation of cognitive symptoms and symptoms related to alpha adrenergic activation. Copyright © 2014 Elsevier Inc.

    From 1973 through 1978, the Center for Disease Control identified ten deaths caused by ruptured ectopic pregnancy after attempted legal abortions for those pregnancies. The women ranged in age from 18 to 31 years, seven were black, three were white, and five were nulliparous. The estimated gestational age was 16 menstrual weeks or earlier. In seven cases tissue obtained at abortion was sent for outside microscopic pathological examination; attempts to contact four of the patients when no products of conception were found were unsuccessful. An important factor in preventing fatal ectopic pregnancy for women who have legal abortions is the identification of products of conception at the time of the abortion procedure while the patient is still available for reexamination and recurretage.

    The beam halo population is a non-negligible factor for the performance of the LHC collimation system and the machine protection. In particular this could become crucial for aiming at stored beam energies of 700 MJ in the High Luminosity (HL-LHC) project, in order to avoid beam dumps caused by orbit jitter and to ensure safety during a crab cavity failure. Therefore several techniques to safely deplete the halo, i.e. active halo control, are under development. In a first attempt a novel way for safe halo depletion was tested with particle narrow-band excitation employing the LHC Transverse Damper (ADT). At an energy of 450 GeV a bunch selective beam tail scraping without affecting the core distribution was attempted. This paper presents the first measurement results, as well as a simple simulation to model the underlying dynamics.

    In the article, the problem of estimating the lifespan of the magnetic lens' (horns) structure, is discussed. Due to pulse-type excitation by current flow, the relatively broad frequency band of stress component function is obtained. Moreover, due to repetition, the problem of pulse resonance can be obtained. The fatigue life prediction is done on the spectral attempt. The analysis was performed for two types of horn structures: the CERN NuFACT one and the EUROnu designed one.

  17. Factors Related in Suicide Attempts in Admitted Poisoned Patients

    2015-07-01

    Full Text Available Introduction Suicide is considered as a public health problem. Approximately 0.9% of all deaths worldwide are due to suicide. This study was performed to identify risk factors of suicide attempts among patients who admitted in a medical toxicology centre during three months. Materials and Methods: A cross sectional study was carried out; all admitted patients in our medical toxicology centre due to suicidal attempt who completed consent form were included from December to March 2013. A researcher designed questionnaire was prepared and its validity and reliability was confirmed; it was fulfilled by a psychologist via clinical interview. Data were analyzed by SPSS software 11.5 and results were discussed. Results:198 participants included; of whom 67.2% were female and 94.9% were less than 45 year old. Among the patients, approximately 48% of the patients were married; 27.77% were employed. More than 96% suffered from severe depression, 3.53% of the patients had psychotic symptoms. Personality disorders, previous suicidal attempt, unemployment, full stressed family, family history of suicidal attempt, moderate to severe depression and a history of dependence on antipsychotic drugs and lack of family support were identified as risk factors for suicide. Conclusion: Attention to personality trait  and family environment can be mainly effective in long-term prevention of suicide, treatment of physical illness in patients with chronic health conditions, evaluation and treatment of psychiatric issues in addition to family and social problems, and organizing educational courses  to families with suicide history can be helpful.

    Background: Previous studies have noted that a past suicide attempt (SA) predicts a future SA, but few studies have reported whether previous SAs that predict a future attempt differ from those that do not. Knowing which characteristics of previous SAs predict future attempts would assist in evaluating adolescents at risk of attempt repetition. This longitudinal study of an unreferred sample examined which characteristics of adolescent SAs increased risk for repeat attempts. Methods: Fifty...

    Suicide is a major public health problem. It covers about half of violent deaths and results in approximately one million deaths annually. Although completed suicide rates in Colombia are relatively low when compared with other countries, suicidal behavior, represented not only by completed suicide, is a significant mental health problem. To understand life experiences of a group of subjects related to the phenomenon of ideation and suicide attempt. A qualitative study with a psychodynamic approach. In-depth interviews were conducted in order to explore thought processes, emotions, motivations and experiences that underlie and accompany the suicide attempt. Five women and 3 men were interviewed. The average age was 29 years. The exploration of subjective experiences in the present study showed that loneliness and psychic pain were linked to hopelessness, pessimism and discouragement. Also, the illusion of death represents an invitation to suicide attempt. It is important to consider the subjective assessment that patients with suicidal risk make of their depression and stressful life situations. Additionally, the concepts of loneliness and psychic pain have a leading role in the interaction between discourse and the experiences of the participants interviewed.

    Although the power clean is an almost ubiquitous exercise in the strength and conditioning setting, relatively little is known about the biomechanics of successful and unsuccessful power clean lift attempts. The purpose of this study was to determine biomechanical differences between successful and unsuccessful power clean lift attempts in male collegiate athletes. Fifteen male lacrosse players (Age: 20.1 ± 1.2; Height: 1.78 ± 0.07 m; Body mass: 80.4 ± 8.1 kg; Relative one-repetition maximum power clean: 1.25 ± 0.13 kg/kg) were videotaped during a lifting session that required the completion of maximal effort power cleans to establish a one-repetition maximum. The position of the barbell was digitised and used to calculate the displacement, velocity, acceleration, and acceleration vector of the barbell. The results revealed that unsuccessful attempts were characterised by differences during the second pull phase. Unsuccessful lifts exhibited greater peak forward barbell displacement, lower backward barbell velocities, and lower resultant acceleration angles during the second pull. Strength and conditioning coaches should therefore emphasise limited forward motion of the barbell during the second pull and instruct athletes to generate a more backward-directed force during the second pull in order to lift greater loads during testing and subsequent lifting sessions.

  2. Cross-Cultural Leadership

    2015-05-01

    Full Text Available Ongoing low participation of women in global leadership calls for more research in this field. In this article, we set out to include gendered expectations toward leader behavior as part of cross-cultural leadership theory. Building on an existing body of research, we focus on propositions about the effects of gendered expectations on the leader, from the followers’ standpoint. The consideration of gendered effects from the follower standpoint is an under-researched area in leadership literature, and it is even more rarely to be found in empirical data. In every culture, there are certain expectations toward leaders of the two genders that influence their behavior. In this article, we will attempt to answer the following question: How does perceived leader behavior and gendered behavior relate to national culture and actual leader behavior? We present a conceptual model that seeks to incorporate gendered expectations into cross-cultural leadership as an answer. Moreover, we provide a conceptual guideline toward operationalization of the model. The model includes the potential of dissonance between male expectations as a dominating leadership role and female leadership. This might serve as an explanation as to why in some cases women are not seen as successful as men when they adopt a masculine leadership style. The article seeks to advance cross-cultural leadership theory by focusing on expected gendered leadership behavior. Our ideas and model could eventually contribute to the advancement of leadership theory, as well as contributing to gender studies, cross-cultural leadership, and business communication.

    To summarize the way North Korea attempted to modernize its system of traditional medicine and integrate it with Western biomedicine. We reviewed clinical textbooks and periodicals of traditional Korean medicine published in North Korea, research reports on North Korean health and medicine published elsewhere, and conducted interviews of defectors from North Korea who were students or clinicians of traditional medicine. Key findings of this study are: (1) North Korea has attempted several ways of integrating traditional medicine into education and clinical practices; (2) North Korea's communist government provided the main driving force for an integration policy; (3) school curricula of both Western and traditional Korean medicine incorporated knowledge of both disciplines, yet more weight was placed on traditional Korean medicine; (4) a combination of Western diagnosis and Korean therapeutics was the most frequent example of integration, while the dual system approach with reciprocal practice was also explored; (5) several forms of integrative therapeutic mixture were practiced including concurrent medication, injection on acupuncture points, and intramuscular or intravenous injection of extracts from medicinal plants; and (6) limited resources for research and the underdeveloped level of clinical research failed to secure rigorous scientific advancement. Despite the government-driven attempt to create an ideal integrative system of medicine, according to our findings, the actual introduction of an integrative system into practice was far from the North Korean government's anticipated outcome in regards to clinical practice. We hypothesize this was due to famine, economic crisis, and political isolation from the international realm. Traditional Korean medicine seems to have served the population, which is in desperate need of treatment amid difficulties in health, while North Korea's Western biomedicine-based health delivery system has been badly affected.

    Suicidal behavior among children has significantly increased in Morocco. We conducted a study on the epidemiological aspect to propose a treatment strategy. Descriptive retrospective study over a period of 3 years (April 2012-April 2015) involving children who visited pediatric medical emergencies of the Children Hospital of Rabat after an autolysis attempt. We observed epidemiological parameters, history, social and family context, the means used, the presumed cause, clinical manifestation, and the management. 66 patients were identified. A female predominance was found (sex =15). The average age was 13 years old. This was a first episode in 97% of cases. Psychiatric history was found in 6 patients. The causes of suicide attempt were unidentified in 65%. The most frequent cause was family conflict (35%). The most frequent method was pharmaceutical drug ingestion (54.4%). Children were asymptomatic (57.6%). Neurological manifestations (30%) were most frequent. Digestive symptoms (12%) and hemodynamic (3%) were also discovered. Patients were hospitalized in a general pediatric service 92.4% of the times, admitted to intensive care 4.5% of the times, and two patients refused to be hospitalized. The treatment consisted of gastric lavage (18%) supplemented by symptomatic measures. The outcome was favorable in 95.4% of cases. We recorded 2 deaths by rat poison poisoning. All patients were advised in writing after leaving to follow up with a psychological treatment. Suicide attempts are the result of an ill being, mostly among children living in a family with conflict. Upstream treatment is essential to identify children at risk. Additionally, a psychiatric care in hospital is essential to avoid recurrences.

    Research has demonstrated that patients with insomnia are at an increased risk of experiencing suicidal ideation and/or making a suicide attempt. To evaluate the relation between insomnia and suicidal behaviour. To examine factors associated with a diagnosis of insomnia in patients admitted to an Emergency Department (ED) and assessed by the psychiatrist in charge. Participants were 843 patients consecutively admitted to the ED of Sant'Andrea Hospital in Rome, between January 2010 and December 2011. All patients admitted were referred to a psychiatrist. A clinical interview based on the Mini International Neuropsychiatric Interview (MINI) and a semi-structured interview was conducted. Patients were asked about 'ongoing' suicidal ideation or plans for suicide. Forty-eight percent of patients received a diagnosis of bipolar disorder (BD), major depressive disorder (MDD) or an anxiety disorder; whereas, 17.1% were diagnosed with Schizophrenia or other non-affective psychosis. Patients with insomnia (compared to patients without insomnia) more frequently had a diagnosis of BD (23.9% vs. 12.4%) or MDD (13.3% vs. 9.5%; p suicide in the past 24 h (5.3% vs. 9.5%; p suicide more frequently used a violent method (64.3% vs. 23.6%; p suicide attempters. Our results do not support an association between insomnia and suicidal behaviour. However, suicide attempters with insomnia more frequently used violent methods, and this phenomenon should be taken into serious consideration by clinicians. © 2013 John Wiley & Sons Ltd.

    2015-01-01

    To understand the experiences of suicidal persons in Ghana, 10 persons were interviewed after they attempted suicide. Thematic analysis of data showed that motivation for suicidal behavior included social taunting, hopelessness, and partner's infidelity. Suicidal persons reported stigma expressed through physical molestation and social ostracism, which left them traumatized. However, they coped through social support from relations, religious faith, and use of avoidance. Community-wide sensitive education should target reducing stigma and also increase mental health education on suicidal behavior in Ghanaian communities.

    This study attempts to identify predictors of early heroin addiction. Natives of low social class origins are, as predicted by "social structure and anomie theory," more likely to be addicted when young. However, social class has little impact on age of addiction among migrants. Blue-collar migrants are strikingly less likely than blue-collar natives to be addicted when young; a nonsignificant trend in the same direction is found for white-collar respondents. Findings are interpreted in terms of commitment to traditional values. Contrary to expectations based on Moynihan, family intactness is unrelated to age of addiction.

    Cultural neuroscience issues from the apparently incompatible combination of neuroscience and cultural psychology. A brief literature sampling suggests, instead, several preliminary topics that demonstrate proof of possibilities: cultural differences in both lower-level processes (e.g. perception, number representation) and higher-order processes (e.g. inferring others’ emotions, contemplating the self) are beginning to shed new light on both culture and cognition. Candidates for future cultural neuroscience research include cultural variations in the default (resting) network, which may be social; regulation and inhibition of feelings, thoughts, and actions; prejudice and dehumanization; and neural signatures of fundamental warmth and competence judgments.

    There has been a long culture war over the validity of "Wikipedia" for research. Many university departments banned it as a primary source starting around 2007, but many others still allow it as a heuristic prompt. Certainly, one knows that students are still going to "Wikipedia" and dabbling in it. This reflects a recent gain in "Wikipedia"…

    Suicide risk behavior is a significant contributor to the mortality and morbidity of schizophrenia. We previously reported affected sibship status in a Xhosa schizophrenia or schizoaffective disorder sample to be protective in nature; given the counterintuitive nature of this finding, we expanded the sample size to seek further clarification. Subjects were assessed with the Diagnostic Interview for Genetic Studies and then stratified into two groups: with (n = 137) or without (n = 837) a previous suicide attempt. The presence of lifetime bizarre behavior (OR 1.5; 95% CI 1.12-1.87) or cannabis use or abuse (OR 1.2; 95% CI 10.01-1.47) was a significant predictor of suicide attempts, while a higher global alogia score (OR 0.84; 95% CI 0.74-0.96) was a protective factor. Our data seem to support that in this population, encouraging family members to report bizarre behavior and implementing dual diagnosis interventions for cannabis use or abuse could be an appropriate starting point toward developing a targeted suicide prevention program for further research. © 2013 The American Association of Suicidology.

  19. ĐURO AUGUSTINOVIĆ'S ATTEMPT TO REFORM ORTOGRAPHY

    2011-01-01

    Full Text Available The essay depicts an attempt to reform ortography taken by a military doctor Đuro Augustinović through which he strived to unify the Southslavic people, especially the Croats and the Serbs. The potential movements that he was exposed to and that he was influenced by were stated in the essay, along with his persevere promotion of his own standpoint. Since his proposal appeared in amidst of Gaj's triumphant orto-graphical proposals, his ideas were not widely accepted. In the spirit of ongoing Panslavic movements Augustinović insisted on reconstruction of Latin script by introducing Cyrillic graphems (in opposition to Gaj's solutions which involved diacritic signs intending to unify in writing the two bigger nations. This equilization of Cyrillic and Latin script failed because both, the Croats and the Serbs had a deep-rooted tradition which prevented every intervention in its core. His untiring advocating of phonetical solutions in ortographical issues had a similar destiny. Therefore, Augustinović's attempt remained solely a testimony of an era without a true impact.

  20. Male brush-turkeys attempt sexual coercion in unusual circumstances.

    2014-07-01

    Sexual coercion by males is generally understood to have three forms: forced copulation, harassment and intimidation. We studied Australian brush-turkeys, Alectura lathami, to determine whether some male behaviours towards females at incubation mounds could be classified as aggressive, whether males were attempting sexual coercion and, if so, whether the coercion was successful. We found that some male behaviours towards females were significantly more likely to be followed by the cessation of female mound activity, and hence could be classified as aggressive, while others were significantly more likely to be followed by the commencement of female mound activity, and hence could be classified as enticing. Copulation was preceded by higher rates of male enticement and by higher rates of certain types of male aggression. It therefore seemed that males were attempting sexual coercion. There was little evidence, however, that this combination of coercion and enticement was successful in obtaining copulations. While forced copulation did occur, it was infrequent, and no evidence could be found for intimidation. We conclude that harassment is the primary form of sexual coercion by male brush-turkeys. Although sexual coercion is understood to be a sub-optimal tactic, brush-turkey sexual coercion was employed as a primary tactic by dominant males who owned incubation mounds. One possible explanation for this apparent paradox is that aggression is the default solution for social conflicts in this species, and hence can be interpreted as a behavioural syndrome.

    Western mediterranean fluvial history - an attempt to correlate Dominik Faust & Daniel Wolf (TU Dresden, Germany) Correlation of fluvial sediments over large distances is a challenging issue. However it is worth to try it when reliable and robust data are available. Location of the sites to be correlated play a decesive role. So we considered possible pitfalls (tectonic activity, halokinetic movements, sea level changes, disorder inherent to the system itself) to find and chose the best exposures in order to built up a standard profile for every single river system. Three selected rivers were worked out in detail, the Guadalquivir sequences however are used complementary . We attempt to correlate • The Oued Medjerda standard profile from Northern Tunisia (Faust et al. 2004; Zielhofer & Faust 2008) • The Rio Jarama standard profile for Central Spain (Wolf et al. 2013) • The Rio Guadalete standard profile for Southern Spain (Wolf et al. in review) • (The Rio Guadalquivir) We aim to propose a correlation scheme in order to visualize analog and inconsistent trends and to discuss possible driving forces. dominik.faust@tu-dresden.de

    Full Text Available First attempts are described to prepare a precursor for an all-carbon analog of indigo, the tetracyclic triene 4. Starting from indan-2-one (9 the α-methylene ketone 13 was prepared. Upon subjecting this compound to a McMurry coupling reaction, it dimerized to the bis-indene derivative 17, rather than providing the tetramethyl derivative of 4, the hydrocarbon 14. In a second approach, indan-1-one (18 was dimerized to the conjugated enedione 21 through the bis-1-indene dimer 19. All attempts to methylenate 21 failed, however. When 19 was treated with the Tebbe reagent, the dimer 23 was produced, presumably through a Cope reaction of the intermediately generated isomer 22. The bis-indene derivative 23 can be alkylated with 1,2-dibromoethane to produce a 1:1 mixture of the spiro compounds 24 and 25. Although 9 could be reductively dimerized to 30, the conversion of this olefin to 14 failed.

    The division between the two cultures of the literary and scientific worlds is considered, as is the division between the two cultures of humanism and somaticism. The development of psychiatric thought important to this latter dichotomy is described through the Age of Enlightenment, the Romantic Movement and the New Enlightenment. The two cultures of our present literary and scientific milieux are equated with the romanticism and somaticism of the past. The development of two cultures in psychiatry is traced, beginning with Freud's attempt to combine science and romanticism, to the present day where one finds some degree of convergence between the somatic and psychoanalytic approaches. Criteria are presented for a greater union of the two cultures in psychiatry. PMID:20328284

    Full Text Available This article aims at contributing to an integrated understanding of Malik Bennabi's view of culture and cultural transformation. An attempt is made to analyze Bennabi's concepts and ideas that constitute the core of his study of culture and its dynamic civilizing function. The paper introduces Bennabi's understanding of culture as a project with a pivotal educational value. His cultural envisioning shows that ethics, aesthetics, practical reasoning and technical skills form the nucleus of any civilizational change. The paper highlights Bennabi's view that culture is an important social and educational agent of change that can restore the sense of efficacy and creativity to the Islamic society.

    This study tracked student self-assessments of cultural awareness at regular intervals during the first year of a master's of science physician assistant (PA) program to test effectiveness of a cultural competency component in the curriculum. Students completed a cultural awareness survey at the beginning of the program and retook the survey at approximately 4-month intervals throughout the first year. Regression analyses confirmed positive linear relationships between survey number and score on 31 of 31 items. Cultural awareness among PA students benefits from repeated exposures to lessons on cultural competency. Schools attempting to develop or expand cultural awareness among students should consider presenting material in multiple courses across terms.

  14. Cultural universals: So what?

    Directory of Open Access Journals (Sweden)

    M. Elaine Botha

    1989-03-01

    Full Text Available The search for the elusive "cultural universal s” in a variety of academic disciplines has been motivated b y the spectre of relativism in its diverse guises. The problem of relativism has been thrust upon us inter alia by the inability of our epistemological models to account for social and cultural, moral and cognitive diversity and to provide us with criteria by means of which to judge aberrations like ideologies. Contrary to the general trend I would like to argue that it is not the spectre of relativism in its various guises which necessitates the search for cultural universals, nor is this the only motivation for a Christian to argue in favour of the recognition of cultural universals. Various authors have suggested that such universal structures do exist; that they condition human and societal behaviour and that it would in principle be possible to construct a theory of these structural universals or a "biogrammar" or "geography ” of the universal cultural acquisition device of humankind (cf. Harre,1976, 32; Johnson, 1987: xxxvii ; Tige r and Fox, 1974:17,30. Cross -cu ltural research in both psychology and anthropology has pointed to the existence of such traits, and in recent philosophical discussions Apel and others have pointed to the necessity of recognizing the existence of some sort of " transcendentalia" . These arguments emphasize elements that are common to diverse approaches to the problem of cultural universals. Christian scholars could accept most of these arguments as valid and yet argue in favour of a very specifically modified version of the notion of cultural universals. This essay attempts to develop such a position.

    2014-12-01

    Full Text Available The authors contributed during a quite long period of time to the development of comprehensive and flexible system of estimating seismic intensity on the basis of instrumental (accelerographic data on earthquake ground motion. The system makes it possible to determine for a record, according to needs, global intensities, intensities corresponding to definite frequencies, intensities averaged upon a spectral band, continuous or discrete intensity spectra. Moreover, the intensity measures developed may rely, according to choice, on different outcomes of processing of primary instrumental data. A problem to which the paper is devoted is represented by the calibration of an important parameter, namely the logarithm base adopted in view of conversing instrumental information to intensity measures. After the attempts of the past, new sources are used this time to solve the problem. Alternative solutions are examined and discussed in this view.

    2016-01-01

    A case of an attempted mass shooting at a large psychiatric hospital in the United States by a 30-year-old male with severe mental illness, somatic delusions, and exceptional access to healthcare professionals is reported. Six persons were shot, one died at the scene, and the shooter was then killed by the police. Data were gathered from court documents and media accounts. An analysis of the shooter's psychiatric history, his interactions with healthcare professionals, and communications prior to the shooting suggest a rare form of mass murder, a random attack by a documented psychotic and delusional individual suffering with somatic delusions. Despite his being psychotic, the killer planned the attack and made a direct threat 1 month prior to the shootings. This case highlights problems with the healthcare system, indicating that it might be ill equipped to appropriately deal with severe mental illness. © 2015 American Academy of Forensic Sciences.

    de Beer, Wayne; DeWitt, Bernard; Schofield, Jules; Clark, Helen; Gibbons, Veronique

    2018-02-23

    The primary aim of this audit was to determine the quality of psychiatric risk assessments conducted by Mental Health & Addiction Services clinicians for patients presenting to the emergency department, Waikato Hospital, Hamilton, New Zealand following an attempted suicide. A retrospective, randomised audit of 376 files of patients who had presented to the ED over a 12-month period from 1 July 2015 to 30 June 2016 was conducted, following the standards outlined in the present New Zealand Ministry of Health Clinical Practice Guideline for Deliberate Self Harm (DSH). It was found that clinicians routinely focused on the historical features of the suicide attempt presentation while failing to record judgements about future suicidal behaviours. Interactions with family members were recorded in less than half of the cases. The guideline most poorly adhered to was checking whether Māori patients wanted culturally appropriate services during the assessment and treatment planning, with this recorded in less than 10% of the clinical records. To improve the quality of the suicide risk assessments, and to better align with Clinical Practice Guidelines, the authors propose redevelopment of clinician training, including focus on cultural competence, and training in confidentiality and privacy relating to an attempted suicide episode.

    Suicide is a complex behavior with biological, psychological and social causes. It has predisposing family factors such as domestic violence, psychiatric disorders and parents' alcohol abuse. Suicides have increased in children and adolescents in the last decades and it is now the third leading cause of death. Mexico has the second place in mortality in adolescents between 10-14 years old, of which 21.9 % are suicides. This study aimed to determine the frequency of suicide attempts using drugs in children and adolescents in a tertiary care hospital and to identify the causes. A retrospective and descriptive study was performed considering socioeconomic, cultural and biological issues related to suicide attempts using drugs in children and adolescents who were attended at the National Institute of Pediatrics from January 1995 to March 2005. A total of 141 drug intoxication cases were detected including 47 suicide attempts; 25 girls and 22 boys, with a median of 13 years of age. The most frequently drug classes used were analgesics 21 of 47 cases and antidepressants 11 of 47 cases. Risk factors were parents' divorce and family dysfunction in 16 of 47 cases of the population. Suicidal behavior in children and adolescents can be a way to attract attention, as well as an alarm signal asking for help. Analgesics and antidepressants are drugs commonly used in suicide attempts.

    Culture pervades human lives and has allowed our species to create niches all around the world and its oceans, in ways quite unlike any other primate. Indeed, our cultural nature appears so distinctive that it is often thought to separate humanity from the rest of nature and the Darwinian forces that shape it. A contrary view arises through the recent discoveries of a diverse range of disciplines, here brought together to illustrate the scope of a burgeoning field of cultural evolution and to facilitate cross-disciplinary fertilization. Each approach emphasizes important linkages between culture and evolutionary biology rather than quarantining one from the other. Recent studies reveal that processes important in cultural transmission are more widespread and significant across the animal kingdom than earlier recognized, with important implications for evolutionary theory. Recent archaeological discoveries have pushed back the origins of human culture to much more ancient times than traditionally thought. These developments suggest previously unidentified continuities between animal and human culture. A third new array of discoveries concerns the later diversification of human cultures, where the operations of Darwinian-like processes are identified, in part, through scientific methods borrowed from biology. Finally, surprising discoveries have been made about the imprint of cultural evolution in the predispositions of human minds for cultural transmission. PMID:21357216

    . Interviews therefore centred on specific and limited practitioner activity. Each transcription was submitted to a Qualitative Analysis of Discourse, followed by a comparative analysis of the 10 transcriptions. We propose an original method of Qualitative Analysis of Discourse, to be applied to semi-structured clinical interviews. This method seeks to analyse the structure of the resulting egocentric monologue in research si-tuations of semi-directive interviewing. The method of Quali-tative Analysis of Discourse involves three steps, but only the first two were applied in this work: a) identification of sequences of discourse; b) analysis of relationships between statements; c) stylistic analysis of figures of speech. Our first set of analyses showed that seve-ral markers increase in physicians' discourse when they describe difficult and/or conflict-laden consultation situations: logical connectors, impersonal pronouns, reported discourse, anti-cipations regarding the interviewer's judgement. The logical balance of the discourse therefore appears threatened when pro-blems inherent in the work demands involved in ending IVF attempts are mentioned. As a whole, these markers underscore the importance of the implicit dimension of discourse (inferences, presuppositions, hints, allusions, etc.), thus reflecting complex speech that attempts to negotiate between subjective positions and shared cultural values. A comparative analysis of the markers identified in the 10 interviews revealed four areas, each involving nervous tension poles, that are suggestive of cognitive-emotional dissonance in the task to be performed. Some factors increase professional distress while others temper it. They act upon the work situation itself on the one hand, and on the working relationship between physician and patient on the other. 1. Areas of tension relating to the task to be performed. The first area contrasts individual with collective decision-making. The independent status which characterises

    Full Text Available Teachers should care for the emotional stability of their students, teachers must take on the work of social workers, teachers have to answer to those problems caused by the difficult socio-economic situation facing our students... Today, phrases like these are common in discussions among teachers and non-teachers. All of them, one way or another, relate to teacher's identity, and all are trying to tell their own truth about what is like being a teacher today. Obviously, not all refer to the processes of learning or teaching learning problems. What is then the identity of a teacher? What does the word "teacher" encapsulate in its meaning in today's society? We will try to make an approach to the definition of a teacher's identity but not looking for a single, dogmatic definition, but by highlighting some landscapes that will identify this territory. Our position will be, therefore, that of a cartographer trying to peer into the world through his own observations (provided he has the ability to travel to the land he is trying to represent, or with data from narratives of those who have traveled there already, or through representations made by others before him. Certainly, like any map, our representation will not be a finished product , but an attempt to present to other man and woman signs to orientate themselves in this new territory and that they themselves will enrich with their personal contributions.

    Full Text Available The video Skyvelære (While Attempting to Balance portrays the 11th International Pyrheliometer Comparison Event (IPC-XI. Here, metrologists representing 45 different countries, accomplished the meticulous calibration of their Pyrheliometers, an instrument for measuring the energy emitted form the sun. Realized by artist Ellen Røed as part of her fellowship in artistic research at Bergen National Academy of Art and Design, it constitutes a reflection on the production of knowledge. Composed of the words sliding and knowing, the norwegian term Skyvelære means caliper, a device which, by means of a set edge and a variable slide operated by the thumb, can be used to measure distance and depth in great detail. In the video, the production and use of units and set reference points are presented as a social project in which people relate to the world collectively. The video was part of the final result of Røeds fellowship project that was presented as a solo exhibition in 2013. Here, the video was presented as a projection with surround sound. In this number of In Formation the video is presented as an individual piece of video art, accompagnied with a text.

    A lot of efforts are directed now to study the interactions between energy and climate because of their significant importance for our planet. Globally, energy related emissions of Greenhouse Gases (GHGs) contribute for atmospheric warming. On regional level, where it is more difficult to determine concrete direction of climate variability and change, the role of energy remains considerable being not so direct as in the case of emissions` impact. Still there is essential necessity for further analyses and assessments of energy related climate variations and change in order to understand better and to quantify the energy - climate relations. In the presentation an attempt is made to develop approach for assessment of energy related climate variations on regional level. For this purpose, data and results from the research within Bulgarian Case Study (BCS) in the DECADES Inter-Agency Project framework are used. Considering the complex nature of the examined interconnections and the medium stage of the Study`s realisation, at the moment the approach can be presented in conceptual form. Correspondingly, the obtained results are illustrative and preliminary

    To describe the involvement and input of physicians and nurses in cardiopulmonary resuscitation (CPR / do not attempt resuscitation (DNAR) decisions; to analyse decision patterns; and understand the practical implications. A Qualitative Grounded Theory study using one-time open-ended interviews with 40 volunteer physicians and 52 nurses drawn from acute care wards with mixes of heterogeneous cases in seven different hospitals in German-speaking Switzerland. Establishing DNAR orders in the best interests of patients was described as a challenging task requiring the leadership of senior physicians and nurses. Implicit decisions in favour of CPR predominated at the beginning of hospitalisation; depending on the context, they were relieved/superseded by explicit DNAR decisions. Explicit decisions were the result of hierarchical medical expertise, of multilateral interdisciplinary expertise, of patient autonomy and/or of negotiated patient autonomy. Each type of decision, implicit or explicit, potentially represented a team consensus. Non-consensual decisions were prone to precipitate personal or team conflicts, and, occasionally, led to non-compliance. Establishing DNAR orders is a demanding task. Reaching a consensus is of crucial importance in guaranteeing teamwork and good patient care. Communication and negotiation skills, professional and personal life experience and empathy for patients and colleagues are pivotal. Therefore, leadership by experienced senior physicians and nurses is needed and great efforts should be made with regard to multidisciplinary education.

    Full Text Available Penetrating cranial injury by mechanisms other than are exceedingly rare, and so strategies and guidelines for the management of PBI are largely informed by data from higher-velocity penetrating injuries. Here we present a case of penetrating brain injury by the low velocity mechanism of a harpoon from an underwater fishing speargun in an attempted suicide by a 56-year-old Caucasian male. The case raised a number of interesting points in management of lower-velocity penetrating brain injury (LVPBI, including benefit in delaying foreign body removal to allow for tamponade; the importance of history taking in establishing the social/legal significance of the events surrounding the injury; the use of cerebral angiogram in all cases of PBI; advantages of using DECT to reduce artifact when available; and antibiotic prophylaxis in the context of idiosyncratic histories of usage of penetrating objects before coming in contact with the intracranial environment. We present here the management of the case in full along with an extended discussion and review of existing literature regarding key points in management of LVPBI vs. higher velocity forms of intracranial injury.

  12. A Survey of Physical Principles Attempting to Define Quantum Mechanics

    Science.gov (United States)

    Oas, Gary; Acacio de Barros, J.

    Quantum mechanics, one of the most successful theories in the history of science, was created to account for physical systems not describable by classical physics. Though it is consistent with all experiments conducted thus far, many of its core concepts (amplitudes, global phases, etc.) can not be directly accessed and its interpretation is still the subject of intense debate, more than 100 years since it was introduced. So, a fundamental question is why this particular mathematical model is the one that nature chooses, if indeed it is the correct model. In the past two decades there has been a renewed effort to determine what physical or informational principles define quantum mechanics. In this chapter, recent attempts at establishing reasonable physical principles are reviewed and their degree of success is tabulated. An alternative approach using joint quasi-probability distributions is shown to provide a common basis of representing most of the proposed principles. It is argued that having a common representation of the principles can provide intuition and guidance to relate current principles or advance new principles. The current state of affairs, along with some alternative views are discussed.

  13. A Brief History of Attempts to Measure Sexual Motives

    Full Text Available Artists, creative writers, and musicians have long been interested in the complex motives that spark passionate love, sexual desire, and sexual behavior. Recently, scholars from a variety of disciplines have begun to investigate two questions: “Why do men and women choose to engage in sexual liaisons?” “Why do they avoid such encounters?” Theories abound. Many theorists have complained that there exists a paucity of scales designed to measure the plethora of motives that prompt people to seek out or to avoid sexual activities. In fact, this observation is incorrect. Many such scales of documented reliability and validity do exist. The reason that few scholars are familiar with these scales is that they were developed by psychometricians from a variety of disciplines and are scattered about in an assortment of journals, college libraries, and researchers’ desk drawers, thus making them difficult to identify and locate. This paper will attempt to provide a compendium of all known sexual motives scales, hoping that this will encourage scholars to take a multidisciplinary approach in developing typologies of sexual motives and/or in conducting their own research into the nature of sexual motives.

  14. An attempt to electrically enhance phytoremediation of arsenic contaminated water

    Water polluted with arsenic presents a challenge for remediation. A combination of phyto- and electro-remediation was attempted in this study. Four tanks were setup in order to assess the arsenic removal ability of the two methods separately and in combination. Lemna minor was chosen for As remediation and collected from a ditch in Utrecht, The Netherlands. The tanks were filled with surface water without any pre-cleaning, therefore containing various elements including metals as Mn (2.9mgL -1), Cu (0.05mgL -1), Fe (1.39mgL -1), and Ba (0.13mgL -1). This water was then spiked with As and allocated to a feed container, guaranteeing a continuous flow of 0.12mLs -1 to each tank. Two experiments were performed: Exp. 1 with 3 consecutive stages with rising applied voltage and Exp. 2, with a constant voltage over a period of 6d. Measurements of pH and temperature were taken every working day, as well as water samples from outlets of all tanks including feed container for control. From the present study, there was no evidence that As had been taken up by the plants, but a strong depletion of As was observed in the tanks where current was applied. Preliminary results clearly showed that applying voltage to the electrodes caused 90% removal of As from the spiked surface water. © 2012 .

  16. Culture and demoralization in psychotherapy.

    In most societies, members of a culture have attempted to help each other in times of trouble with various types of healing methods. Demoralization - an individual experience related to a group phenomenon - responds to certain elements shared by all psychotherapies. This article has three objectives: (1) to review the theoretical background leading to our current views on culture and demoralization in psychotherapy, (2) to discuss the methodological challenges faced in the cross-cultural study of demoralization and psychotherapy, and (3) to describe the clinical applications and research prospects of this area of inquiry. Demoralization follows a shattering of the individual's assumptive world and it is different from homeostatic responses to a stressful situation or from depressive disorders. Only a few comparative studies of this construct across cultures have been undertaken. The presentation of distress may vary widely from culture to culture and even within the same culture. To avoid 'category fallacy', it is important to understand the idioms of distress peculiar to a cultural group. A cultural psychiatrist or psychotherapist would have to identify patient's values and sentiments, reconstruct his/her personal and collective ambient worlds, and only then study demoralization. The limitations of our current diagnostic systems have resulted in methodological challenges. Cultural clinicians should consider using a combination of both 'clinimetric' and 'perspectivistic' approaches in order to arrive at a diagnosis and identify the appropriate intervention. The presenting problem has to be understood in the context of the patient's individual, social and cultural background, and patients unfamiliar with Western-type psychotherapies have to be prepared to guide their own expectations before the former are used. Future research should identify the gaps in knowledge on the effectiveness of cultural psychotherapy at reversing or preventing demoralization. Copyright

    Full Text Available Overall, few advances in the cryopreservation of complex cells such as oocytes, embryo or tissue have been registered and in less quantity have been reported for aquatic species. Abalone has high economic interest worldwide and the conservation of abalone germplasm may help to enhance its culture and develop repopulation programs. In this work, we reported the cytotoxic effect of two concentration of trehalose (0.2 and 0.4 M on red abalone oocytes incubated for 10, 15 and 20 min. Also, we reported the cryopreservation of red abalone oocytes using a 3-steps cryopreservation protocol and 5 thawing protocols. Significant differences on cytotoxic effect were found (p<0.01. However, none of the cryoprotectant was optimum to cryopreserve red abalone oocyte. In conclusion, it is necessary to find an appropriate method to dehydrate or make the cryoprotectant penetrate on the abalone oocyte before proceeding to cryopreservation.

  19. What Interrupts Suicide Attempts in Men: A Qualitative Study.

    Full Text Available Despite higher rates of suicide in men, there is a dearth of research examining the perspectives and experiences of males at risk of suicide, particularly in terms of understanding how interventions can be tailored to men's specific needs. The current study aimed to examine factors assisting, complicating or inhibiting interventions for men at risk, as well as outlining the roles of family, friends and others in male suicide prevention. Thirty-five male suicide survivors completed one-to-one interviews, and forty-seven family and friends of male suicide survivors participated in eight focus groups. Thematic analysis revealed five major themes: (1 development of suicidal behaviours tends to follow a common path associated with specific types of risk factors (disrupted mood, unhelpful stoic beliefs and values, avoidant coping strategies, stressors, (2 men at risk of suicide tend to systematically misinterpret changes in their behaviour and thinking, (3 understanding mood and behavioural changes in men enables identification of opportunities to interrupt suicide progression, (4 distraction, provision of practical and emotional supports, along with professional intervention may effectively interrupt acute risk of harm, and (5 suicidal ideation may be reduced through provision of practical help to manage crises, and helping men to focus on obligations and their role within families. Findings suggest that interventions for men at risk of suicidal behaviours need to be tailored to specific risk indicators, developmental factors, care needs and individuals' preferences. To our knowledge this is the first qualitative study to explore the experiences of both suicidal men and their family/friends after a suicide attempt, with the view to improve understanding of the processes which are effective in interrupting suicide and better inform interventions for men at risk.
