Transnational reflections on transnational research projects on men, boys and gender relations

This article reflects on the research project, ‘Engaging South African and Finnish youth towards new traditions of non-violence, equality and social well-being’, funded by the Finnish and South African national research councils, in the context of wider debates on research, projects and transnational processes. The project is located within a broader analysis of research projects and projectization (the reduction of research to separate projects), and the increasing tendencies for research to be framed within and as projects, with their own specific temporal and organizational characteristics. This approach is developed further in terms of different understandings of research across borders: international, comparative, multinational and transnational. Special attention is given to differences between research projects that are in the Europe and the EU, and projects that are between the global North and the global South. The theoretical, political and practical challenges of the North-South research project are discussed

Recent advances in understanding regulation of the Arabidopsis circadian clock by local cellular environment.

Circadian clocks have evolved to synchronise an organism's physiology with the environmental rhythms driven by the Earth's rotation on its axis. Over the past two decades, many of the genetic components of the Arabidopsis thaliana circadian oscillator have been identified. The interactions between these components have been formulized into mathematical models that describe the transcriptional translational feedback loops of the oscillator. More recently, focus has turned to the regulation and functions of the circadian clock. These studies have shown that the system dynamically responds to environmental signals and small molecules. We describe advances that have been made in discovering the cellular mechanisms by which signals regulate the circadian oscillator of Arabidopsis in the context of tissue-specific regulation

Online healthy lifestyle support in the perinatal period: What do women want and do they use it?

Unhealthy weight gain and retention during pregnancy and postpartum is detrimental to mother and child. Although various barriers limit the capacity for perinatal health care providers (PHCPs) to offer healthy lifestyle counselling, they could guide women to appropriate online resources. This paper presents a project designed to provide online information to promote healthy lifestyles in the perinatal period. Focus groups or interviews were held with 116 perinatal women and 76 PHCPs to determine what online information perinatal women and PHCPs want, in what form, and how best it should be presented. The results indicated that women wanted smartphone applications (apps) linked to trustworthy websites containing short answers to everyday concerns; information on local support services; and personalised tools to assess their nutrition, fitness and weight. Suggestions for improvement in these lifestyle areas should be practical and tailored to the developmental stage of their child. PHCPs wanted evidence-based, practical information, presented in a simple, engaging, interactive form. The outcome was a clinically endorsed website and app that health professionals could recommend. Preliminary evaluation showed that 10.5% of pregnant women in Western Australia signed up to the app. Use of the app appeared to be equitable across urban and rural areas of low to middle socioeconomic status

Progressive Star Bursts and High Velocities in the Infrared Luminous, Colliding Galaxy Arp 118

In this paper we demonstrate for the first time the connection between the spatial and temporal progression of star formation and the changing locations of the very dense regions in the gas of a massive disk galaxy (NGC 1144) in the aftermath of its collision with a massive elliptical (NGC 1143). These two galaxies form the combined object Arp 118, a collisional ring galaxy system. The results of 3D, time-dependent, numerical simulations of the behavior of the gas, stars, and dark matter of a disk galaxy and the stars and dark matter in an elliptical during a collision are compared with multiwavelength observations of Arp 118. The collision that took place approximately 22 Myr ago generated a strong, non-linear density wave in the stars and gas in the disk of NGC 1144, causing the gas to became clumped on a large scale. This wave produced a series of superstarclusters along arcs and rings that emanate from the central point of impact in the disk. The locations of these star forming regions match those of the regions of increased gas density predicted the time sequence of models. The models also predict the large velocity gradients observed across the disk of NGC 1144. These are due to the rapid radial outflow of gas coupled to large azimuthal velocities in the expanding ring, caused by the impact of the massive intruder.Comment: 12 pages in document, and 8 figures (figures are separate from the document's file); Submitted to Astrophysical Journal Letter

Engaging Primary Health Care Providers in the Promotion of Healthy Weight Among Young Children: Barriers and Enablers for Policy and Management

Recent national efforts to stem the alarming growth of childhood overweight and obesity in Australia have highlighted the importance of preventative strategies that focus beyond the child-on parents, families, primary health care providers (PHCPs) and child care services. But, while such efforts have to date focused on school-based interventions, once poor eating habits and sedentary lifestyles have set in, a growing body of research is indicating that PHCPs can play a more influential role in monitoring and modifying factors affecting prevention and early intervention in preschool children. This paper presents the findings of a systematic review to: (a) identify key barriers to the effective engagement of PHCPs with parents and child care staff in the promotion of healthy weight among children aged 2-6 years, (b) appraise promising interventions for strengthening the capacity of PHCPs to effectively deal with these barriers, and (c) synthesise policy options to encourage and engage PHCPs. The study draws on the lessons of promising interventions to highlight the urgent need to address organisational, attitudinal, knowledge, skills and training barriers, to facilitate the engagement of PHCPs in different settings-based environments (clinical, child care, home and community)

Ngala Healthy You, Healthy Baby: a personalized online program to support healthy weight in pregnancy and early life

Perinatal maternal obesity is common and has significant child and maternal health consequences. Online resources have the potential to engage young mothers to adopt healthier lifestyles during pregnancy and postpartum. Intercept interviews with 53 pregnant women at antenatal clinics and focus groups with 67 new mothers at mothers’ groups and playgroups were conducted to determine preferred types and formats of online information and support. The expressed needs of women were matched to behaviour change theory to guide development of the Healthy You Healthy Baby website and Smartphone application. A mix of factual and practical online information, self-assessment, goal-setting and feedback in an interactive format is recommended to motivate and support women to achieve healthy lifestyles in the perinatal period. Referral to online resources by health professionals and quality assurance of content is important to increase the confidence of women to act on it

Geo-hydrological hazard underlined by toponymy of Italian Military Geographycal Institute maps at 1:25,000 scale. Contributions to the knowledge of floodplain and hillslope dinamycs

Toponymy is a linguistic discipline, which has already been used as a tool for geographical studies in Italy and particularly in Liguria. Geographical studies have already classified the toponyms in several categories: physical geography, human geography and socio-economic geography. By selecting the place names connected to physical geography, we study those suggesting the presence of landslides or floods. We focussed on the Italian Military Geographic Institute maps at 1: 25.000 scale, edited between 1936-1939 and related to a territory approximately located between Genoa and Chiavari, in Ligurian coastal area, and Tortona and Piacenza in Po valley. On the Ligurian slopes we have examined the maps relating to the Polcevera, Bisagno and Entella streams catchments. For the Po side we dealt with maps of the Scrivia and Trebbia rivers catchments: From the Ligurian-Po watershed, these rivers flow into the Adriatic Sea. The place names have been compared with landslide and flood hazard maps of Basin Master Plans for geo-hydrological risk reduction. The toponyms feature a linguistic layer linked to different historical periods. In particular in the study area several layers have been recognized: the ancient Ligurian pre-Roman, Latin, ancient Lombard, vulgar Gaulish-Italic of local languages and Italian terms related to the twentieth century. The first three layers and the last one match in the entire area of study. The vulgar Gaulish-Italic is structured into two Ligurian and Emilian groups: the latter is further splitted into the Oltrepo variants of Tortona and Piacenza. The identified names were distinguished in related-landslides or floods. In addition, the toponyms have been further divided into three linguistic influence areas: Ligurian, from Ligurian Sea up to Novi Ligure and Bobbio, the language of Tortona, downstream of Novi Ligure and Piacenza from Bobbio to Po river. Overall, place names linked to physical geography features represent nearly 25% of toponyms with a density of about 0.5 per km2. Almost half of these are toponyms related to landslides, floods or predisposing factors such as erosion, steepness or water. The names of places linked to landsliding prevail in Liguria, while those related to the waters or floods in the Po areas are located in plain areas or in very gentle slopes. The most common names related to landslides or erosion are \u201cmoggia\u201d, \u201cliggia\u201d or \u201ccrosi\u201d and similar, which respectively mean swampy deposits, landslides or gullies. Names related to floods are \u201criva\u201d, \u201cpiana\u201d \u201cponte\u201d or \u201cisola\u201d which mean respectively edge of fluvial scarp, floodplain, bridge or isle. The comparison with the Basin Master Plan gave satisfying results: we found a good correspondence between names and geo-hydrological hazard. The use of toponyms allowed a geographycal interpretation of the slope and floodplain dynamics. It suggests a possible use of toponymys in land planning activities

Subtropical Real Root Finding

We describe a new incomplete but terminating method for real root finding for large multivariate polynomials. We take an abstract view of the polynomial as the set of exponent vectors associated with sign information on the coefficients. Then we employ linear programming to heuristically find roots. There is a specialized variant for roots with exclusively positive coordinates, which is of considerable interest for applications in chemistry and systems biology. An implementation of our method combining the computer algebra system Reduce with the linear programming solver Gurobi has been successfully applied to input data originating from established mathematical models used in these areas. We have solved several hundred problems with up to more than 800000 monomials in up to 10 variables with degrees up to 12. Our method has failed due to its incompleteness in less than 8 percent of the cases

Integrable System Constructed out of Two Interacting Superconformal Fields

We describe how it is possible to introduce the interaction between superconformal fields of the same conformal dimensions. In the classical case such construction can be used to the construction of the Hirota - Satsuma equation. We construct supersymmetric Poisson tensor for such fields, which generates a new class of Hamiltonin systems. We found Lax representation for one of equation in this class by supersymmetrization Lax operator responsible for Hirota - Satsuma equation. Interestingly our supersymmetric equation is not reducible to classical Hirota - Satsuma equation. We show that our generalized system is reduced to the one of the supersymmetric KDV equation (a=4) but in this limit integrals of motion are not reduced to integrals of motion of the supersymmetric KdV equation.Comment: 15 pages,late

An investigation of the existence of a surface water layer on aircraft radomes during simulated flight in heavy precipitation

An experiment to investigate the electromagnetic attenuation effects of an impacting water spray on an aircraft weather radome was conducted in Langley's 4 X 7 m. wind tunnel equipped with a water spray system. Results indicate no significant liquid water film formed at the stagnation point of the radome under the test conditions. However, a water sheath was observed standing away from the radome surface, which could possibly have significant attenuation properties of its own. Due to the lack of fidelity in modeling both the natural environment with the tunnel apparatus and the water sheath, it is recommended that further studies be undertaken to better define the water distribution in the vicinity of the radome and measure its effect on weather radar performance
