Forty years of rainfall variability and extremes in Queensland: contextualising the 2010/11 floods
Creators: name: O'Brien, G
Publisher: name: University Of Tasmania
Year: 2023

description: In the Australian summer of 2010/11, Queensland experienced extensive flooding with the flooding occurring during a particularly strong La Ni‚àö¬±a event. The December Southern Oscillation Index (SOI) was +27.1 (National Climate Centre 2011), the highest December value on record and the highest monthly value since 1973, whilst other indicators of La Ni‚àö¬±a also indicate the strongest event since at least the mid-1970s, and one of the four strongest events of the last century (National Climate Centre 2011). The main purpose of this research is to investigate the 2010/11 floods and rainfall intensity and to contextualise it against the previous 40 years to understand whether this event can be understood in terms of large scale climate drivers. The coefficient of determination R2 is used to determine the quality of the correlation. The R2 value quantifies the amount of variance explained in the data and/or its relationship with another variable (i.e.: SOI and the percentage of Queensland rainfall stations recording rainfall deciles of 8 and above). An R2 value of 0.4 or above is used to limit the results to correlations where the ENSO indices can account for at least 40% of the occurrences of Queensland high-quality rainfall stations recording rainfall deciles of 8 or above. The research looks at in situ data managed by the Bureau of Meteorology (created originally by Lavery et al. [1997]) to obtain results that show a positive correlation between NI‚àöv´O-4 (and SOI) values and very heavy rainfall indices at Queensland High Quality rainfall gauge stations during La Ni‚àö¬±a events. MATLAB is used create a matrix of the BOM dataset and to generate scripts for producing the correlations between intense Queensland rainfall and the SOI and NINO-4 index. The present study shows that the NINO-4 index and SOI are positively correlated (with varying levels of strength) with Queensland intense rainfall deciles for the periods of spring, summer and December. This study highlights the positive correlations between intense Queensland rainfall and the SOI and NINO-4 index. It also confirms the strong effects that the IPO inflicts on the correlations between SOI, NINO-4 and intense rainfall deciles in Queensland. This study asserts that while flooding of the summer 2010/11 magnitude has only occurred twice since 1970, on both occasions a negative IPO, highly positive SOI and strongly negative NINO-4 index coincided making it highly likely that these climatic conditions (producing a very wet spring followed by a very wet summer) are needed to produce flooding of that magnitude.

description: We present the first three-dimensional (3D) simulations of the large-scale mixing that takes place in the shock-heated stellar layers ejected in the explosion of a 15.5 solar-mass blue supergiant star. The outgoing supernova shock is followed from its launch by neutrino heating until it breaks out from the stellar surface more than two hours after the core collapse. Violent convective overturn in the post-shock layer causes the explosion to start with significant asphericity, which triggers the growth of Rayleigh-Taylor (RT) instabilities at the composition interfaces of the exploding star. Deep inward mixing of hydrogen (H) is found as well as fast-moving, metal-rich clumps penetrating with high velocities far into the H-envelope of the star as observed, e.g., in the case of SN 1987A. Also individual clumps containing a sizeable fraction of the ejected iron-group elements (up to several 0.001 solar masses) are obtained in some models. The metal core of the progenitor is partially turned over with Ni-dominated fingers overtaking oxygen-rich bullets and both Ni and O moving well ahead of the material from the carbon layer. Comparing with corresponding 2D (axially symmetric) calculations, we determine the growth of the RT fingers to be faster, the deceleration of the dense metal-carrying clumps in the He and H layers to be reduced, the asymptotic clump velocities in the H-shell to be higher (up to ~4500 km/s for the considered progenitor and an explosion energy of 10^{51} ergs, instead of <2000 km/s in 2D), and the outward radial mixing of heavy elements and inward mixing of hydrogen to be more efficient in 3D than in 2D. We present a simple argument that explains these results as a consequence of the different action of drag forces on moving objects in the two geometries. (abridged)

Uncertainty and the capital investment decision
Creators: name: Brehaut, Charles Henry
Publisher: name: University of British Columbia
Year: 2011

description: A description of the events that preceeded an actual capital investment decision illustrates the importance of uncertainty in the decision process and provides a basis for developing criteria related to the needs of the decision maker in dealing with uncertainty. The sequence of events leading to the acceptance or rejection of a capital investment proposal is best characterized as a decision process in which uncertainty in the input information is reduced to a level consistent with the risk assuming preferences of the firm. The use of formal methods to relate economic benefits, uncertainty, and the risk assuming preferences of the firm within a single framework has been suggested and two methods, employing subjective probabilities as their distinguishing characteristic, are presented for analysis. The theory of subjective probability is found to gain acceptance only if specific assumptions are judged to be acceptable. A second set of assumptions also requires acceptance to justify utilization of the theory in any given practical situation. The analysis of the two methods, in relation to the criteria developed from the actual example, indicates that complete formalization cannot be attained in that no acceptable means of formally incorporating analysis of the risk assuming preferences of the firm is provided. The use of subjective probabilities serves only to formally combine economic benefits and uncertainty. Use of the resulting probability distributions must be based on an acceptance of the underlying assumptions of the theory and serve only as an aid to judgement. Any decision for the use of subjective probability distributions must rest with the individual decision maker.

description: We investigate the binding surface along the Bain path and phonon dispersion relations for the cubic phase of the ferromagnetic binary alloys Fe3X (X = Ni, Pd, Pt) for L12 and DO22 ordered phases from first principles by means of density functional theory. The phonon dispersion relations exhibit a softening of the transverse acoustic mode at the M-point in the L12-phase in accordance with experiments for ordered Fe3Pt. This instability can be associated with a rotational movement of the Fe-atoms around the Ni-group element in the neighboring layers and is accompanied by an extensive reconstruction of the Fermi surface. In addition, we find an incomplete softening in [111] direction which is strongest for Fe3 Ni. We conclude that besides the valence electron density also the specific Fe-content and the masses of the alloying partners should be considered as parameters for the design of Fe-based functional magnetic materials.

description: As they do not rely on the presence of any crystal symmetry, Weyl nodes are robust topological features of an electronic structure that can occur at any momentum and energy. Acting as sinks and sources of Berry curvature, Weyl nodes have been predicted to strongly affect the transverse electronic response, like in the anomalous Hall or Nernst effects. However, to observe large anomalous effects the Weyl nodes need to be close to or at the Fermi level, which implies the band structure must be tuned by an external parameter, e.g., chemical doping. Here we show that in a ferromagnetic metal tuning of the Weyl node energy and momentum can be achieved by rotation of the magnetization. First, taking as example the elementary magnet hcp-Co, we use electronic structure calculations based on density-functional theory to show that by canting the magnetization away from the easy axis, Weyl nodes can be driven exactly to the Fermi surface. Second, we show that the same phenomenology applies to the kagome ferromagnet Co3Sn2S2, in which we additionally show how the dynamics in energy and momentum of the Weyl nodes affects the calculated anomalous Hall and Nernst conductivities. Our results highlight how the intrinsic magnetic anisotropy can be used to engineer Weyl physics.
The responsibility to protect : no more Rwandas : the international community and humanitarian intervention in the 21st century
Creators: name: Potter, DW
Publisher: name: University Of Tasmania
Year: 2023

description: Humanitarian intervention lies at the fault-line in international relations between the principles of international law and state sovereignty (pluralism) on the one hand, and morality and the protection of human rights (solidarism) on the other. Whereas the pluralist international-society theory defines humanitarian intervention as a violation of the cardinal rules of order, it is being challenged by the solidarist view, that seeks to strengthen the legitimacy of the international community by developing its commitment to justice. As a result, a solidarist international community is one in which states accept a moral responsibility to protect the security, not only of their own citizens, but of humanity everywhere. The humanitarian tragedies in Somalia, Rwanda and Srebrenica in the 1990s and in Darfur currently, have highlighted to the international community the need for the notion of sovereignty to be re-defined, to permit intervention in support of the emerging norm of the responsibility to protect. In the 21st century, a state that violates the fundamental norms of human rights by failing to provide for the safety, security and well-being of its citizens creates a legal and moral burden on the international community to act. This dissertation contends that the international community has a legal and moral responsibility to intervene to prevent humanitarian emergencies. To test the veracity of this thesis, it was assessed against a number of case studies that span India's intervention into East Pakistan in 1971 to the ongoing crisis in Darfur in 2006. While many aspects of humanitarian intervention remain contentious this dissertation found that there is a trend towards the solidarist approach that is reflected in the emerging international norm of the \responsibility to protect\". Further it confirmed that the most successful interventions involve a range of actors usually the United Nations and/or a regional organisation backed by a hegemonic power. Finally it found that a successful humanitarian intervention is dependent upon the international community's commitment to understanding the gravity of the situation at hand and if necessary confronting the Westphalian tradition of sovereignty to provide the appropriate institutional support and resources and the political will to mobilise that capacity in the face of other priorities and preoccupations."

description: The light-induced processes occurring in two dye-catalyst assemblies for light-driven hydrogen production were investigated by ultrafast transient absorption spectroscopy. These dyads consist of a push-pull organic dye based on a cyclopenta[1,2-b:5,4-b’]dithiophene (CPDT) bridge, covalently linked to two different H2-evolving cobalt catalysts. Whatever the nature of the latter, photoinduced intramolecular electron transfer from the excited state of the dye to the catalytic center was never observed. Instead, and in sharp contrast to the reference dye, a fast intersystem crossing (ISC) populates a long-lived triplet excited state, which in turn non-radiatively decays to the ground state. This study thus shows how the interplay of different structures in a dye-catalyst assembly can lead to unexpected excited state behavior and might open up new possibilities in the area of organic triplet sensitizers. More importantly, a reductive quenching mechanism with an external electron donor must be considered to drive hydrogen production with these dye-catalyst assemblies. © 2020 by the authors.

Infrared exponents and the strong-coupling limit in lattice Landau gauge

description: We study the gluon and ghost propagators of lattice Landau gauge in the strong-coupling limit beta=0 in pure SU(2) lattice gauge theory to find evidence of the conformal infrared behavior of these propagators as predicted by a variety of functional continuum methods for asymptotically small momenta $q^2 \ll Λ_\mathrm{QCD}^2$. In the strong-coupling limit, this same behavior is obtained for the larger values of a^2q^2 (in units of the lattice spacing a), where it is otherwise swamped by the gauge field dynamics. Deviations for a^2q^2 < 1 are well parameterized by a transverse gluon mass $\propto 1/a$. Perhaps unexpectedly, these deviations are thus no finite-volume effect but persist in the infinite-volume limit. They furthermore depend on the definition of gauge fields on the lattice, while the asymptotic conformal behavior does not. We also comment on a misinterpretation of our results by Cucchieri and Mendes in Phys. Rev. D81 (2010) 016005.

description: We report a times series of B-band photometric observations initiated on the eve of Valentine's day, February 14, 2009, at the anticipated time of a transit of the extrasolar planet HD 80606b. The same transit has been observed independently (Fossey et al. 2009; Moutou et al. 2009). For one transit model favored by the data, minimum light equals 0.990 times the nominal brightness of HD 80606 and occurs at HJD 2454876.33. The latter time, combined with the orbital period $P = 111.4277 \pm 0.0032$ days, longitude of periastron, $ω= 300.4977 \pm 0.0045$ degrees, and time of mid-secondary eclipse HJD $2454424.736 \pm 0.003$ (Laughlin et al. 2009), refines the orbital eccentricity and inclination. The duration of the model transit is 0.47 days, and its four contacts occur at HJD 2454876 plus 0.10, 0.24, 0.42, and 0.57 days. We describe parameterizations of a transit model with mutually accommodating eccentricity, $e = 0.9337^{+0.0009}_{-0.0006}$, inclination, $i = 89.26^{+0.24}_{-0.09}$ degrees, and the planetary radius in units of the stellar radius \RpRs$ = 0.11^{+0.04}_{-0.02}$.

description: Over a hundred species of Iberian Opisthobranchs have been grouped according to their ecological, biological and other characters (food, substrate, habits, defence, reproduction, development, size, etc.); the results of a principal component analysis show the formation of assemblages whose general attributes divide the species, more or less neatly, in r-strategists (Tectibranchs) and K-strategists (Nudibranchs). On a r-K continuum, certain orders are more r-selected (Cephalaspidea, etc.), others more K-selected (Doridacea), and other share a diverse amount of pioneer and conservative attributes (Aeolidiacea, Sacoglossa, etc.). A study of the relations between number of eggs per spawn mass and egg diameter, and between egg diameter and the product (°C x days of development) in the different developmental types shows also the divergent evolutive or adaptive options

description: A linear approach to the phenomenon of irregular amplitude modulation of beam-driven Langmuir waves, developed in a previous paper, is extended to explain periodic modulation as well. It comes about by beating of the fastest growing mode of the instability with beam-aligned plasma oscillations. They are naturally generated in a uniform domain of beam-plasma interaction prior to the onset of the instability. Particle-in-cell (PIC) simulations support the results of the linear analysis.

description: The search of ways to generalize the theory of strong MHD turbulence for the case of non-zero cross-helicity (or energy imbalance) has attracted considerable interest recently. In our earlier publications we performed three-dimensional numerical simulations and showed that some of existing models are inconsistent with numerics. In this paper we focused our attention on low-imbalance limit and performed new high-resolution simulations. The results strongly suggest that in the limit of small imbalances we smoothly transition to a standard Goldreich-Sridhar (1995) balanced model. We also claim that Perez-Boldyrev (2009) model that predicts the same nonlinear timescale for both components due to so-called "dynamic alignment" strongly contradicts numerical evidence.

Down sendromu tedavi edilmesi gereken bir hastalık değil, genetik bir farklılıktır.

Down sendromuna sebep olduğu bilinen tek etmen hamilelik yaşıdır, 35 yaşüstü hamileliklerde risk artar. Ancak genel olarak genç kadınlar daha fazla bebek sahibi olduğundan Down sendromlu çocukların %75-80'i genç annelerin bebekleridir.

Ortalama her 800 doğumda bir görülür. Türkiye'de tam bir veri yok ama yaklaşık 70.000 Down sendromlu kişi olduğu tahmin ediliyor.

Hafif veya orta seviye zihinsel ve fiziksel gelişim geriliğine sebep olur.

Bu gelişim geriliği de dil konuşma problemlerine yol açar. Dolayısıyla DKT'lerin klinik hayatlarında sıkça karşılarına çıkacak olan bu bireyleri yakından tanımaları oldukça önemlidir.

A Comparative study of test procedures and measures of behaviour in the male three-spined stickleback, (Gasterosteus aculeatus L.)
Creators: name: Wootton, Robert John
Publisher: name: University of British Columbia
Year: 2011

description: This study compared three methods used to measure aggression in the male three-spined stickleback. These methods have been used in different studies without the certainty that they measure the same behavioural phenomenon. A number of different measures of aggression must be highly correlated if aggression in the male stickleback is to be regarded as a unitary drive. The methods consisted of recording the behaviour of an experimental male when: (i) a tube containing another male (or a female in some tests) was visible for 5 min; (ii) another male was visible across a glass partition at all times; (iii) a fish-shaped wax model was visible for 2 min. Each method showed that in the 12 days after fertilization of an egg-mass, there was a U-shaped trend in frequency of biting, frequency of charging and the rate of biting per minute spent oriented towards the other fish or the model. In Method (i), total oriented time formed about 70 % of a test period and this measure was not correlated with frequency of biting, nor did it follow a U-shaped trend. In Methods (ii) and (iii), total oriented time formed less than 50 % of a test period, was correlated with frequency of biting, and did follow a U-shaped trend. In Methods (i) and (ii), the measures, frequency of biting and bites per min of oriented time were at a maximum in the first 15 min after fertilization. Method (iii) did not show this maximum in biting. All methods showed that frequency of biting, of charging, and bites per min of oriented time were higher for fish with nests than for fish which had yet to build nests. Gonadectomy of fish with nests reduced all measures to the levels found for intact fish that did not have nests. An experiment using only Method (i) showed that a male with a nest attacked another male more than a non-gravid female. A male without a nest attacked both a male and a non-gravid female equally. The use of more than one measure for a behaviour pattern improved both the comparisons between methods and the analysis of changes in behaviour of the male. Examples of this are given for biting and parental fanning. Results from Method (iii) were not always consistent with those from Methods (i) and (ii). Method (iii) was exceptional in the number of charges the experimental males made with both dorsal and ventral spines erect. A wider range of behaviour patterns were recorded more regularly in Method (ii) than in Method (i). But these two methods consistently showed the same trends in frequency of biting, charging and bites per min of oriented time. In spite of the similarities in the results from the three methods there was not sufficient evidence to conclude that aggression in the male stickleback is a unitary drive and that all potential measures of aggression will be equivalent.

description: The synthesis of new materials that can host magnetic skyrmions and their thorough experimental and theoretical characterization are essential for future technological applications. The β-Mn-type compound FePtMo3N is one such novel material that belongs to the chiral space group P4132, where the antisymmetric Dzyaloshinskii-Moriya interaction is allowed due to the absence of inversion symmetry. We report the results of small-angle neutron scattering (SANS) measurements of FePtMo3N and demonstrate that its magnetic ground state is a long-period spin helix with a Curie temperature of 222 K. The magnetic field-induced redistribution of the SANS intensity showed that the helical structure transforms to a lattice of skyrmions at ∼13 mT at temperatures just below TC. Our key observation is that the skyrmion state in FePtMo3N is robust against field cooling down to the lowest temperatures. Moreover, once the metastable state is prepared by field cooling, the skyrmion lattice exists even in zero field. Furthermore, we show that the skyrmion size in FePtMo3N exhibits high sensitivity to the sample temperature and can be continuously tuned between 120 and 210 nm. This offers different prospects in the control of topological properties of chiral magnets. © 2020 authors. Published by the American Physical Society.

description: We study the stochastic motion of a relativistic trailing string in black hole AdS_5. The classical string solution develops a world-sheet horizon and we determine the associated Hawking radiation spectrum. The emitted radiation causes fluctuations on the string both above and below the world-sheet horizon. In contrast to standard black hole physics, the fluctuations below the horizon are causally connected with the boundary of AdS. We derive a bulk stochastic equation of motion for the dual string and use the AdS/CFT correspondence to determine the evolution a fast heavy quark in the strongly coupled $\N=4$ plasma. We find that the kinetic mass of the quark decreases by $ΔM=-\sqrt{γλ}T/2$ while the correlation time of world sheet fluctuations increases by $\sqrtγ$.

An investigation into the ontological significance of sculptural objects
Creators: name: Langridge, CF
Publisher: name: University Of Tasmania
Year: 2023

description: The research is developed through sculptural artworks that seek to raise the question of their being. They do this through their indeterminate presence, which often awakens people to ask 'What is it?' I ask how sculpture can encourage people to wonder about what things are, and how the relationship/s we form with art can then lead us to reflect upon our other more worldly relationships. I also pursue the questions of what is sculpture, and what is contemporary art, in order to map out an understanding of the domain of my practice, and the issues at stake regarding the making and display of sculpture. Through a reading of the ideas of Martin Heidegger and other Continental philosophers, I have focused upon the way our (Modern Western) relationship with things in the world is problematic, and how art can help us to address some of these problems. It is through art's poetic ambiguities that our usual determined and closed relationship with the world can be opened up to other readings. An investigation into contemporary art practices reveals several issues that put the artwork into context and shed light upon difficulties facing contemporary artists particularly in terms of: what am I to do, why should I do it and how should I proceed? My artworks are aimed at raising questions for the viewer about being, sculpture and contemporary art. I have developed the coopering technique of wooden construction to make unusually shaped wooden container-like sculptures. I have also investigated other semi-industrial working methods to construct sculptural objects that oscillate between various possibilities for the viewer. These artworks operate in the field between the familiar/unfamiliar, functional/non-functional and the known/unknown. They resist the viewer's efforts at stilling the oscillation between possible readings and evade some of the common roles of contemporary art such as being a site for social and political dialogue or being a reflection of contemporary/pop/consumer culture. This project contributes to the dialogue already in play between several Post-Minimal sculptors whose work touches upon constructed and or manufactured ambiguous forms. It further develops the language of how to discuss these issues through my philosophical readings. It extends the coopering technique beyond the simple cask form to discover the technical possibilities for this method of construction. It brings to the gallery visitor an actual experience of what Heidegger writes about art, particularly in terms of his ideas about 'the truth of being as revealing/concealing'. The research also develops our understanding of the nature of contemporary art through questioning several aspects of it and through adopting outmoded and laborious methods of making that are at odds with our digital age. The artworks are the result of working toward a position of indeterminacy that is alluring, by partially resisting the viewer's efforts to know them.

description: Space cooling and heating currently result in huge amounts of energy consumption and various environmental problems. Herein, a switching strategy is described for efficient energy-saving cooling and heating based on the dynamic cavitation of silicone coatings that can be reversibly and continuously tuned from a highly porous state to a transparent solid. In the porous state, the coatings can achieve efficient solar reflection (93%) and long-wave infrared emission (94%) to induce a subambient temperature drop of about 5 °C in hot weather (≈35 °C). In the transparent solid state, the coatings allow active sunlight permeation (95%) to induce solar heating to raise the ambient temperature from 10 to 28 °C in cold weather. The coatings are made from commercially available, cheap materials via a facile, environmentally friendly method, and are durable, reversible, and patternable. They can be applied immediately to various existed objects including rigid substrates.

description: The way knowledge is shared is experiencing a paradigm shift: Digital networks allow new degrees of openness for research and its resources, accompanied by a huge potential for scientists, inventors, industry and the general public. Accessible data will allow all groups to participate in innovation and value creation regardless of their geographical location or individual background. However, for researchers who are evaluated by their academic performance and scientific excellence, there is a fine balance between benefits and concerns regarding the openness of resources such as knowledge and data. With the Research Data Repository (RADAR) project we provide solutions to maintain this balance: In RADAR, an interdisciplinary infrastructure for the preservation, publication, creditability and traceability of research data from the fields of the 'long tail of science' is developed. Here we present the first RADAR prototype: A robust, generic end-point data repository which enables clients to preserve research results up to 15 years and assign well-graded access rights, or to publish and preserve data with a DOI assignment for an unlimited period of time. Potential clients include libraries, research institutions, publishers and open platforms which require an adaptable digital infrastructure to archive and publish data according to their institutional needs and workflows. In a nutshell, RADAR can help clients to handle following issues: - Secure storage of research data. - Preservation of information after a project is completed, a grant ends or employees leave. - Traceable and citable data publication across communities via a discipline-agnostic metadata scheme. - Ensuring that data are ‘stable’ after publication e.g. to allow accurate comparisons later. - Provision of data management services for their customers up front while using RADAR as a back-end system.

description: High-resolution x-ray diffraction measurements reveal an unusually strong response of the lattice to superconductivity in Ba[Fe(1-x)Cox]2As2. The orthorhombic distortion of the lattice is suppressed and, for Co-doping near x = 0.063, the orthorhombic structure evolves smoothly back to a tetragonal structure. We propose that the coupling between orthorhombicity and superconductivity is indirect and arises due to the magneto-elastic coupling, in the form of emergent nematic order, and the strong competition between magnetism and superconductivity.

description: Multiplex immunohistochemistry (mIHC) enables simultaneous staining of multiple immune markers on a single tissue section. Mounting studies have demonstrated the versatility of mIHC in evaluating immune infiltrates in different diseases and the tumour microenvironment (TME). However, the majority of published studies are limited to the analysis of human patient samples. Performing mIHC on formalin-fixed paraffin-embedded (FFPE) mouse tissues, particularly with sensitive antigens, remain challenging. The aim of our study was to develop a robust and reproducible protocol to uncover the immune landscape in mouse FFPE tissues. Effective antibody stripping while maintaining sensitivity to antigens and tissue adhesion to the glass slide is critical in developing an mIHC panel to allow successive rounds of staining. Thus, we identified a highly efficient stripping method that preserves signal intensity and antigenicity to allow multiple rounds of staining. We subsequently optimised an mIHC workflow with antibodies specific against CD4, CD8α, FOXP3 and B220 to identify distinct T and B cell populations on mouse FFPE tissues. Lastly, the application of this mIHC panel was validated in a mouse model of inflammatory bowel cancer, two allograft mouse models of spontaneous colon adenocarcinoma and a sporadic mouse model of colon cancer. Together, these demonstrate the utility of the aforementioned protocol in establishing the quantity and spatial localisation of immune cells in different pathological tissues.
Sports supplements : motivations and correlates of use
Creators: name: Ansell, ML
Publisher: name: University Of Tasmania
Year: 2023

description: Body image issues of females have been thoroughly researched. There is now increasing research on male body image issues. Research shows males are concerned about being unmuscular and females are concerned about being thin. These concerns lead to different diet and exercise behaviour, as well as other behaviours. Males who reported using anabolic steroids to improve their appearance had higher levels of body image symptomology, is this the same for supplement users? The present study aimed to explore this by understanding the motivations and correlates of sports supplement use. 103 participants (M=24.5, SD= 5.8 years) completed an online survey asking about sports supplements use, the motivations for use and potential correlates (attitudes towards supplements and exercise, eating disorder behaviour, drive for muscularity and quality of life) of use. Male supplement users had a significantly greater drive for muscularity than female supplement users (p <.001, d = 1.13) and this drive was significantly correlated (p <.001) with using supplements to change appearance. Increased frequency of supplement use was associated with increased drive for muscularity, compulsive attitudes towards supplements and exercise, and quality of life. These findings suggest the presence of body image issues in male supplement users, calling for further research.

description: Este estudio presenta una metodología diferencial para analizar la competitividad departamental en Colombia y sus implicaciones en políticas públicas. Utilizando Análisis de Datos Evolventes (DEA), Regresión de mínimos cuadrados parciales (PLS) e Índice de crecimiento ponderado (ICP), se examinan procesos transversales, dinámicas y entornos competitivos. Los hallazgos principales revelan heterogeneidad en competitividad y destacan la necesidad de políticas adaptativas y específicas. Se argumenta que el Índice Departamental de Competitividad (IDC) estandarizado es insuficiente para evaluar progreso territorial, lo que puede conducir a una inadecuada priorización de estrategias. El enfoque propuesto contribuye a mejorar decisiones en políticas públicas y estrategias de desarrollo, siendo adaptable a otros contextos regionales y nacionales

One of the greatest challenges in research is to connect and report on distributed services and this incubator explores how richer reporting, impact tracking and usage data can be provided through ORCID iDs and PIDs across national research infrastructure.
Beyond Beer's Law: Why the Index of Refraction Depends (Almost) Linearly on Concentration

description: Beer's empiric law states that absorbance is linearly proportional to the concentration. Based on electromagnetic theory, an approximately linear dependence can only be confirmed for comparably weak oscillators. For stronger oscillators the proportionality constant, the molar attenuation coefficient, is modulated by the inverse index of refraction, which is itself a function of concentration. For comparably weak oscillators, the index of refraction function depends, like absorbance, linearly on concentration. For stronger oscillators, this linearity is lost, except at wavenumbers considerably lower than the oscillator position. In these transparency regions, linearity between the change of the index of refraction and concentration is preserved to a high degree. This can be shown with help of the Kramers–Kronig relations which connect the integrated absorbance to the index of refraction change at lower wavenumbers than the corresponding band. This finding builds the foundation not only for refractive index sensing, but also for new interferometric approaches in IR spectroscopy, which allow measuring the complex index of refraction function. © 2020 The Authors.
