Developing targets and strategies for school-based injury prevention programs to reduce alcohol associated transport risks

Background There is considerable and ongoing debate about the role and effectiveness of school-based injury prevention programs in reducing students’ later involvement in alcohol associated transport injuries. Most relevant literature is concerned with pre-driving and licensing programs for middle age range adolescents (15-17 years). This research team is concerned with prevention at an earlier stage by targeting interventions to young adolescents (13-14 years). There is strong evidence that young adolescents who engage in unsafe and illegal alcohol associated transport risks are significantly likely to incur serious related injuries in longitudinal follow up. For example, a state-wide representative sample of male adolescents (mean age 14.5 years) who reported being passengers of drink drivers were significantly more likely to have incurred a hospitalised injury related to traffic events at a 20 year follow up. Aim This paper reports on first aid training integrated with peer protection and school connectedness within the Skills for Preventing Injury in Youth (SPIY) program. A component of the intervention is concerned with providing strategies to reduce the likelihood of being a passenger of a drink driver and effectiveness is followed up at six months post-intervention. Method In early 2012 the study was undertaken in 35 high schools throughout Queensland that were randomly assigned to intervention and control conditions. A total of 2,521 Year 9 students (mean age 13.5years, 43% male) completed surveys prior to the intervention. Results Of these students 316 (13.7%) reported having ridden in a car with someone who has been drinking. This is a traffic safety behaviour that is particularly relevant to a peer protection intervention and the findings of the six month follow up will be reported. Discussion and conclusions This research will provide evidence as to whether this approach to the introduction of first aid skills within a school-based health education curriculum has traffic safety implications.

Accused headmaster turned me into pedophile, says convicted cleric Peter Gilbert

A CLERGYMAN who allegedly raped boys at a north Queensland boarding school in the 1960s has claimed he was ordered to take female hormones by his headmaster, who encouraged the "romantic love" of children among staff. Former Anglican brother Peter Gilbert - sentenced to seven years' jail in 2006 for the rape and indecent assault of children in the 1980s in South Australia - has blamed St Barnabas headmaster the late Robert Waddington for turning him into a pedophile. In a statement to one of his alleged victims, Gilbert said Waddington was molesting children himself and the Anglican priest would absolve the young teacher of his abuse of children in the confessional. The account has emerged as the top ranks of the Anglican church in Australia and Britain have been rocked by allegations of the covering-up of complaints made in 1999 and 2003 about Waddington's abuse while headmaster at the boarding school in Ravenshoe, north Queensland, and later, when he was dean of Manchester. A full investigation is being demanded into the handling of the complaints by the former Archbishop of York, now Lord (David) Hope of Thornes, and Australian church officials, including the former bishop of north Queensland, Clyde Wood.

The SCRAMSPACE I scramjet flight design and construction

The design activities of the development of the SCRAMSPACE I scramjet-powered free-flight experiment are described in this paper. The objectives of this flight are first described together with the definition of the primary, secondary and tertiary experiments. The Scramjet configuration studied is first discussed together with the rocket motor system selected for this flight. The different flight sequences are then explained, highlighting the SCRAMSPACE I free-flyer separation and re-orientation procedures. A design trade-off study is then described considering vehicle stability, packaging, thermo-structural analysis and trajectory, discussing the alignment of the predicted performance with the mission scientific requirements. The global system architecture and instrumentation of the vehicle are then explained. The conclusions of this design phase are that a vehicle design has been produced which is able to meet the mission scientific goals and the procurement & construction of the vehicle are ongoing.

Chemiluminescence imaging in supersonic combustors operating in radical-farming mode

Emission spectroscopy was used to investigate ignition and combustion characteristics of supersonic combustion ramjet engines. Two-dimensional scramjet models with inlet injection, fuelled with hydrogen gas, were used in the study. The scramjet engines were configured to operate in radical farming mode, where combustion radicals are formed behind shock waves reflected at the walls. The chemiluminescence emission signals were recorded in a two-dimensional, time-integrated fashion to give information on the location and distribution of the radical farms in the combustors. High signal levels were detected in localised regions immediately downstream of shock reflections, an indication of localised hydroxyl formation supporting the concept of radical farming. Results are presented for a symmetric as well as an asymmetric scramjet geometry. These data represent the first successful visualisation of radical farms in the hot pockets of a supersonic combustor. Spectrally resolved measurements have been obtained in the ultraviolet wavelength range between 300 and 400 nm. This data shows that the OH! chemiluminescence signal around 306nm is not the most dominant source of radiation observed in the radical farms.

Melanoma cell colony expansion parameters revealed by approximate Bayesian computation

In vitro studies and mathematical models are now being widely used to study the underlying mechanisms driving the expansion of cell colonies. This can improve our understanding of cancer formation and progression. Although much progress has been made in terms of developing and analysing mathematical models, far less progress has been made in terms of understanding how to estimate model parameters using experimental in vitro image-based data. To address this issue, a new approximate Bayesian computation (ABC) algorithm is proposed to estimate key parameters governing the expansion of melanoma cell (MM127) colonies, including cell diffusivity, D, cell proliferation rate, λ, and cell-to-cell adhesion, q, in two experimental scenarios, namely with and without a chemical treatment to suppress cell proliferation. Even when little prior biological knowledge about the parameters is assumed, all parameters are precisely inferred with a small posterior coefficient of variation, approximately 2–12%. The ABC analyses reveal that the posterior distributions of D and q depend on the experimental elapsed time, whereas the posterior distribution of λ does not. The posterior mean values of D and q are in the ranges 226–268 µm2h−1, 311–351 µm2h−1 and 0.23–0.39, 0.32–0.61 for the experimental periods of 0–24 h and 24–48 h, respectively. Furthermore, we found that the posterior distribution of q also depends on the initial cell density, whereas the posterior distributions of D and λ do not. The ABC approach also enables information from the two experiments to be combined, resulting in greater precision for all estimates of D and λ.

Postglacial Early Permian (late Sakmarian-early Artinskian) shallow-marine carbonate deposition along a 2000 km transect from Timor to west Australia

Late Sakmarian to early Artinskian (Early Permian) carbonate deposition was widespread in the marine intracratonic rift basins that extended into the interior of Eastern Gondwana from Timor in the north to the northern Perth Basin in the south. These basins spanned about 20° of paleolatitude (approximately 35°S to 55°S). This study describes the type section of the Maubisse Limestone in Timor-Leste, and compares this unit with carbonate sections in the Canning Basin (Nura Nura Member of the Poole Sandstone), the Southern Carnarvon Basin (Callytharra Formation) and the northern Perth Basin (Fossil Cliff Member of the Holmwood Shale). The carbonate units have no glacial influence and formed part of a major depositional cycle that, in the southern basins, overlies glacially influenced strata and lies a short distance below mudstone containing marine fossils and scattered dropstones (perhaps indicative of sea ice). In the south marine conditions became more restricted and were replaced by coal measures at the top of the depositional sequence. In the north, the carbonate deposits are possibly bryozoan–crinoidal mounds; whereas in the southern basins they form laterally continuous relatively thin beds, deposited on a very low-gradient seafloor, at the tops of shale–limestone parasequences that thicken upward in parasequence sets. All marine deposition within the sequence took place under very shallow (inner neritic) conditions, and the limestones have similar grain composition. Bryozoan and crinoidal debris dominate the grain assemblages and brachiopod shell fragments, foraminifera and ostracod valves are usually common. Tubiphytes ranged as far south as the Southern Carnarvon Basin, albeit rarely, but is more common to the north. Gastropod and bivalve shell debris, echinoid spines, solitary rugose corals and trilobite carapace elements are rare. The uniformity of the grain assemblage and the lack of tropical elements such as larger fusulinid foraminifera, colonial corals or dasycladacean algae indicate temperate marine conditions with only a small increase in temperature to the north. The depositional cycle containing the studied carbonate deposits represents a warmer phase than the preceding glacially influenced Asselian to early Sakmarian interval and the subsequent cool phase of the “mid” Artinskian that is followed by significant warming during the late Artinskian–early Kungurian. The timing of cooler and warmer intervals in the west Australian basins seems out-of-phase with the eastern Australian succession, but this may be a problem of chronostratigraphic miscorrelation due to endemic faunas and palynofloras.

Erityisopetus muutoksen kynnyksellä - tilastollinen kuvaus erityisopetusjärjestelmästä ja sen määrällisestä kehityksestä 1970-luvun lopulta vuoteen 2008

The number of Finnish pupils attending special education has increased for more than a decade (Tilastokeskus 1999, 2000, 2001, 2003, 2004, 2005a, 2006b, 2007b, 2008b, 2008e, 2009b; Virtanen ja Ratilainen 1996). In the year 2007 nearly third of Finnish comprehensive school pupils took part in special needs education. According to the latest statistics, in the autumn of 2008 approximately 47 000 pupils have been admitted or transferred to special education and approximately 126 000 pupils received part-time special education during the 2007 - 2008 academic year. (Tilastokeskus 2008b, 2009b.) The Finnish special education system is currently under review. The Reform, both in legislation and in practice, began nationwide in the year 2008 (e.g. Special education strategy document, November 2007 and the development project Kelpo). The aim of the study was the statistical description of the Finnish special education system and on the other hand to gain a deeper understanding about the Finnish special education system and its quantitative increase, by analysis based on the nationwide statistical information. Earlier studies have shown that the growth in special education is affected by multiple independent variables and cannot be solely explained by the pupil characteristics. The statistical overview and analysis have been carried out in two parts. In the first part, the description and analysis were based on statistical time series from the academic year 1979 -1980 until 2008. While, in the second, more detailed description and analysis, based on comparable time series from 1995 to 2008 and from 2001-2002 to 2007-2008, is presented. Historical perspective was one part of this study. There was an attempt to find reasons explaining the observed growth in the special needs education from late 1960s to 2008. The majority of the research was based on the nationwide statistics information. In addition to this, materials including educational legislation literature, different kind of records of special education and preceding studies were also used to support the research. The main results of the study, are two statistical descriptions and time series analysis of the quantitative increase of the special needs education. Further, a summary of the plausible factors behind the special education system change and its quantitative increase, is presented. The conclusions coming from the study can be summarised as follows: the comparable statistical time series analysis suggests that the growth in special education after the year 1999 could be a consequence of the changes in the structure of special education and that new group of pupils have been directed to special needs education.

E. G. Gulinin ekumeeninen työ ja ajattelu

This study explores ecumenical activity of professor and bishop E. G. Gulin (1893 1975). Gulin was one of the key figures in the Finland s Evangelical Lutheran Church during the twentieth century. He was also one of the leading persons who imported ecumenical influences from abroad. However, unlike other churches, the Church of Finland did not recognise his importance. For example, in the 1950s Gulin was seen by the Anglicans as a future archbishop for the Evangelical Lutheran Church of Finland. Gulin s career as an ecumenist can be divided to three parts. Between 1917 and 1929, Gulin learned ecumenical working methods in Finland s World Student Christian Federation. He had a background in the revivalist movement, and his parents supported him in his studies. The Evangelical Lutheran Church did not originally play a major role for Gulin, although he was a member. Between 1930 and 1944, Gulin had more and more responsibility as a leading ecumenist in Finland. He became a member of Finland s ecumenical board, Yleiskirkollinen toimikunta. During the Second World War Gulin tried to solicit assistance for Finland s war effort at theological conferences, where Finnish theologians often discussed cooperation among Christians. A third period started in 1945, when Gulin became the bishop of Tampere. His new status in the Evangelical Lutheran Church placed him in a challenging position in ecumenical questions. He had responsibility for inter-church aid in Finland. He also participated in the World Council of Churches (WCC) assemblies in Evanston in 1954 and in New Delhi in 1961. Gulin s role was quite insignificant in those meetings. Closely related to Gulin s texts about ecumenism is kokemus, experience. Gulin wrote about his ecumenical experience or ekumeeninen kokemus. He believed that it was vital for the churches to appreciate their own experiences, since experience was the basis for further development. Yet Gulin mentioned very little about Christian dogma. The main reason seems to have been that he did not believe that a union between churches could be built on dogma.

Postmenopausal hot flushes, vascular health and hormone therapy

Vasomotor hot flushes are complained of by approximately 75% of postmenopausal women, but their frequency and severity show great individual variation. Hot flushes have been present in women attending observational studies showing cardiovascular benefit associated with hormone therapy use, whereas they have been absent or very mild in randomized hormone therapy trials showing cardiovascular harm. Therefore, if hot flushes are a factor connected with vascular health, they could perhaps be one explanation for the divergence of cardiovascular data in observational versus randomized studies. For the present study 150 healthy, recently postmenopausal women showing a large variation in hot flushes were studied in regard to cardiovascular health by way of pulse wave analysis, ambulatory blood pressure and several biochemical vascular markers. In addition, the possible impact of hot flushes on outcomes of hormone therapy was studied. This study shows that women with severe hot flushes exhibit a greater vasodilatory reactivity as assessed by pulse wave analysis than do women without vasomotor symptoms. This can be seen as a hot flush-related vascular benefit. Although severe night-time hot flushes seem to be accompanied by transient increases in blood pressure and heart rate, the diurnal blood pressure and heart rate profiles show no significant differences between women without and with mild, moderate or severe hot flushes. The levels of vascular markers, such as lipids, lipoproteins, C-reactive protein and sex hormone-binding globulin show no association with hot flush status. In the 6-month hormone therapy trial the women were classified as having either tolerable or intolerable hot flushes. These groups were treated in a randomized order with transdermal estradiol gel, oral estradiol alone or in combination with medroxyprogesterone acetate, or with placebo. In women with only tolerable hot flushes, oral estradiol leads to a reduced vasodilatory response and increases in 24-hour and daytime blood pressures as compared to women with intolerable hot flushes receiving the same therapy. No such effects were observed with the other treatment regimes or in women with intolerable hot flushes. The responses of vascular biomarkers to hormone therapy are unaffected by hot flush status. In conclusion, hot flush status contributes to cardiovascular health before and during hormone therapy. Severe hot flushes are associated with an increased vasodilatory, and thus, a beneficial vascular status. Oral estradiol leads to vasoconstrictive changes and increases in blood pressure, and thus to possible vascular harm, but only in women whose hot flushes are so mild that they would probably not lead to the initiation of hormone therapy in clinical practice. Healthy, recently postmenopausal women with moderate to severe hot flushes should be given the opportunity to use hormone therapy alleviate hot flushes, and if estrogen is prescribed for indications other than for the control of hot flushes, transdermal route of administration should be favored.

Three Dimensional Fluorescence Imaging Using Multiple Light-Sheet Microscopy

We developed a multiple light-sheet microscopy (MLSM) system capable of 3D fluorescence imaging. Employing spatial filter in the excitation arm of a SPIM system, we successfully generated multiple light-sheets. This improves upon the existing SPIM system and is capable of 3D volume imaging by simultaneously illuminating multiple planes in the sample. Theta detection geometry is employed for data acquisition from multiple specimen layers. This detection scheme inherits many advantages including, background reduction, cross-talk free fluorescence detection and high-resolution at long working distance. Using this technique, we generated 5 equi-intense light-sheets of thickness approximately 7: 5 mm with an inter-sheet separation of 15 mm. Moreover, the light-sheets generated by MLSM is found to be 2 times thinner than the state-of-art SPIM system. Imaging of fluorescently coated yeast cells of size 4 +/- 1 mm (encaged in Agarose gel-matrix) is achieved. Proposed imaging technique may accelerate the field of fluorescence microscopy, cell biology and biophotonics.

El lenguaje místico en Santa Catalina de Siena

Resumen: El lenguaje místico posee características propias, una de ellas es la inefabilidad. En este artículo la autora, basándose en los conceptos elaborados por M. De Certeau, analiza en primer lugar los rasgos que posee este lenguaje en la obra de Santa Catalina de Siena. En segundo lugar el artículo explora la matriz epistolar que posee Il Dialogo della Divina Provvidenza, la obra más importante de la santa. Aquí se observa de qué manera una gramática hablada conserva las entonaciones propias de la meditación que le da origen. Teniendo su origen en una carta Il Dialogo no sólo manifiesta el lenguaje oral usado en su época sino su estatuto privado y público a la vez.

La génesis del matrimonio civil

Resumen: Es insuficiente para comprender adecuadamente las causas sociales, políticas e ideológicas de la incorporación del matrimonio civil obligatorio a nuestra legislación, el analizar el período histórico próximo a la sanción de la ley 2.393. Por ello hemos organizado la investigación en tres capítulos: “Los matrimonios entre personas de distinta religión”, “Católicos y liberales” y “La Ley de Matrimonio Civil”. El primero abarca la problemática, las distintas soluciones y la legislación aplicable, en el Río de la Plata, desde el tiempo de la colonia hasta la sanción del Código Civil. El segundo, la concepción filosófica de los hombres de la generación del ochenta, protagonistas de la sanción de la ley 2.393, las dos corrientes de pensamiento enfrentadas por su concepto del hombre, la libertad y el Estado, la posición de la prensa, los criterios sustentados por los doctorandos de la época, el fenómeno inmigratorio y el proceso de secularización. Por último, el proyecto de ley, sus repercusiones en la sociedad, en la prensa, el clero y la opinión pública; y su tratamiento en el Congreso de la Nación. Buscamos discernir las causas verdaderas y principales y las ficticias que llevaron a la introducción del matrimonio civil en el derecho argentino, para ello no solo hemos consultado las fuentes habituales, sino que hemos examinado gran cantidad de fuentes originales de la época. Entre ellas, a) la totalidad de los artículos publicados en los diarios La Prensa y La Nación durante el período 1870–1888; b) las Cartas remitidas por el Obispo de Buenos Aires, Monseñor Aneiros y por el Obispo de Córdoba, Fray Reginaldo al Senado de la Nación; c) Actas de las Sesiones de las Cámaras de Diputados y Senadores y d) las tesis doctorales de Francisco Barroetaveña, Daniel Goytia, Julio Sánchez Viamonte, Leopoldo Tahiér, Federico Valdez, Alejandro González Vélez y Alejandro Garramuño.

La teología pastoral de Evangelii Gaudium en el proyecto misionero de Francisco

Resumen: Este ensayo teológico comprende y expone el pensamiento pastoral del Papa Francisco, primer obispo de Roma y Papa latinoamericano, elegido desde las periferias del orbe para guiar al Pueblo de Dios en el corazón de la urbe. Francisco es un pastor misionero y un pastoralista lúcido, que ha enseñado teología pastoral y, lo sigue haciendo, de otra forma, desde el ministerio petrino. La exhortación Evangelii gaudium (2013) condensa de una forma orgánica su mirada a la evangelización en la huella de la exhortación Evangelii nuntiandi de Pablo VI (1975) y del Documento Conclusivo de Aparecida del Episcopado latinoamericano y caribeño (2007). La novedad de su pontificado reformador y misionero hunde sus raíces en la figura singular del jesuita argentino Jorge Mario Bergoglio; en su arraigo en la Iglesia latinoamericana y en el proyecto misionero de Aparecida; y en la incipiente pero promisoria teología argentina postconciliar. El autor hace un pormenorizado estudio sistemático y contextualizado de la exhortación La alegría del Evangelio desde el propio documento y en relación a otros textos de Jorge Bergoglio y, ahora, del Papa Francisco. Articula su discurso en dos momentos mostrando sus interrelaciones. El primero, breve, presenta al sucesor de Pedro como un icono de la fisonomía regional y la reflexión pastoral de la Iglesia latinoamericana. El segundo analiza nueve claves de la Evangelii gaudium: la alegría de evangelizar, síntesis de la mística misionera; la figura de la Iglesia centrada en la misión; la influencia del proyecto misionero de Aparecida; la conversión misionera para la reforma eclesial desde el Concilio Vaticano II; la Iglesia, Pueblo de Dios y Madre de los pueblos, como sujeto de la misión; la fuerza evangelizadora de la piedad católica popular; la revolución de la ternura comunicada en el Evangelio de la misericordia; la dimensión social del Evangelio y de la evangelización; la opción por los pobres desde el corazón de Dios.

San Vicente de Paúl y la oración

Resumen: San Vicente de Paúl se revela no sólo como el santo defensor de los pobres, sino como un maestro de oración. Este artículo quiere detenerse en este último aspecto. Veremos cómo plantea San Vicente la vida de oración y de devoción. Como es un santo minucioso, propio del barroco del siglo XVII, nos señalará detalladamente como se puede mejorar la práctica de la oración. Al mismo tiempo, hará hincapié en que una vida de oración demuestra su coherencia en la medida que se abre a la caridad fraterna y al servicio a los hermanos que padecen. De tal modo, la oración nos capacita para cumplir cabalmente la Voluntad de Dios. Idea que se puede resumir en su frase: “Denme un hombre de oración y será capaz de todo”.

Nueva lectura del concepto de ley natural en Tomás de Aquino : “nueva escuela del derecho natural” o “nueva teoría de la ley natural”

Resumen: La “Nueva Escuela del Derecho Natural” (NEDN) pretende ser una “recuperación” de la “Teoría clásica de la ley natural”. Sus principales representantes son G. Grisez, J. Finnis, J. Boyle, R. P. George y W. May. A ellos se agregan varios pensadores de Estados Unidos y Canadá como R. Shaw, R. Lawler, J. C. Ford, R. A. Connor, T. Kennedy, entre otros. Esta escuela se endilga la recuperación de la versión “auténtica” de Tomás de Aquino de la ley natural, por una reinterpretación de la misma, al entender que ella ha sido deformada por teólogos morales posteriores. En una primera etapa, el trabajo aborda las posiciones centrales de la NEDN, principalmente de Germain Grisez y John Finnis, sin desatender a sus seguidores y críticos. En segundo lugar, y por el planteo de la NEDN, se hace preciso el ocuparse de las fuentes del entredicho, a saber, el concepto de ley en Tomás de Aquino y su impostación en la naturaleza y en la racionalidad práctica.
