description: We analyze a vast light curve database by obtaining mean rotational properties of the entire sample, determining the spin frequency distribution and comparing those data with a simple model based on hydrostatic equilibrium. For the rotation periods, the mean value obtained is 6.95 h for the whole sample, 6.88 h for the Trans-neptunian objects (TNOs) alone and 6.75 h for the Centaurs. From Maxwellian fits to the rotational frequencies distribution the mean rotation rates are 7.35 h for the entire sample, 7.71 h for the TNOs alone and 8.95 h for the Centaurs. These results are obtained by taking into account the criteria of considering a single-peak light curve for objects with amplitudes lower than 0.15 mag and a double-peak light curve for objects with variability >0.15mag. The best Maxwellian fits were obtained with the threshold between 0.10 and 0.15mag. The mean light-curve amplitude for the entire sample is 0.26 mag, 0.25mag for TNOs only, and 0.26mag for the Centaurs. The amplitude versus Hv correlation clearly indicates that the smaller (and collisionally evolved) objects are more elongated than the bigger ones. From the model results, it appears that hydrostatic equilibrium can explain the statistical results of almost the entire sample, which means hydrostatic equilibrium is probably reached by almost all TNOs in the H range [-1,7]. This implies that for plausible albedos of 0.04 to 0.20, objects with diameters from 300km to even 100km would likely be in equilibrium. Thus, the great majority of objects would qualify as being dwarf planets because they would meet the hydrostatic equilibrium condition. The best model density corresponds to 1100 kg/m3.

description: O presente estudo se propõe a analisar a interatividade nos fóruns de discussão em uma proposta de gamificação no Ensino Superior. A Gamificação é o uso de elementos de games em cenários non games como forma de engajar os indivíduos no processo educativo. Na Educação Online ela pode ser uma estratégia didática para a promoção da interatividade. Assim, buscamos analisar as possibilidades da Gamificação para a interatividade em cinco fóruns de discussão no ambiente moodle, na disciplina teorias didáticas, no programa de Pós Graduação em Educação Matemática e Tecnológica da UFPE, em 2015. Através do corpus latente acerca dessas interações no ambiente moodle, buscando verificar a interatividade nos fóruns de discussão. Para a análise de dados realizamos análise de conteúdo através do software WEBQDA. Os resultados mostram que a Gamificação se concretizou como uma estratégia didática de suma relevância, uma vez que possibilitou o concretizar da interatividade em todos os fóruns.

Selecionamos sete vídeos que compõem a unidade temática termoquímica no canal Química em Ação, no Youtube. Tais vídeo-aulas foram assistidas e as falas nas quais emergiam as concepções de calor foram descritas e categorizadas em realista, animista, substancialista, empírica e racionalista, com o auxílio do WebQDA, utilizado também para o cruzamento entre conteúdo e as zonas do perfil conceitual emergentes. Percebemos a maior ocorrência da zona animista, única a emergir em todas as vídeo-aulas, justificado pela abordagem do calor envolvido nas reações químicas na maior parte da unidade temática. Todas as zonas são observadas na abordagem da entalpia de formação. Ainda, podemos observar a emergência de duas zonas do perfil conceitual de calor numa mesma fala, caracterizando um hibridismo entre formas distintas de pensar o conceito de calor.

An exploratory study of education policy and school dropout in Bhutan
Creators: name: Gyamtsho, S
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis examined school dropout in Bhutan in relation to macro-level policy (macro-level policy is policy which affects the whole country) and systemic programmes. An exploratory approach was necessary to appreciate the increase in school dropout in Bhutan. School dropout may appear small in number but its consequences are devastating, diminishing opportunities for personal success, employment and social integration. It is also likely to be associated with antisocial behaviours (substance abuse, criminal activities and misdemeanours). This study explored school dropout as it is becoming a growing problem in Bhutan, with students increasingly dropping out of school. The focus on school dropout so far has been primarily focused at a micro level, in terms of capturing the voices of teachers, students, school leaders, parental perspectives, but very little is known from the perspectives of the policy makers and/or Cabinet Ministries. The aim of this study was to conduct an exploratory study to capture the voices of the current Cabinet Ministers in terms of what explains school dropouts. A study of this nature was necessary as it provided macro level insights into how policy and governmental directives directly or indirectly came to influence student retention. Findings from the study revealed that the five Cabinet ministers with responsibilities that intersected with the issues of school dropout and who were the informants in this study believed the factors that contributed to dropout in Bhutan were socio-economic status (SES), absolute poverty, family and poor academic achievement. These findings can assist in formulating macro level policy which can impact system-wide practice in improving student retention.

description: Motivated by recent observational studies of the environment of z~6 QSOs, we have used the Millennium Run (MR) simulations to construct a very large (~20 deg^2) mock redshift survey of star-forming galaxies at z~6. We use this simulated survey to study the relation between density enhancements in the distribution of i-dropouts and Lya-emitters, and their relation to the most massive halos and protocluster regions at z~6. Our simulation predicts significant variations in surface density across the sky with some voids and filaments extending over scales of 1 degree, much larger than probed by current surveys. Approximately one third of all z~6 halos hosting i-dropouts brighter than z=26.5 mag (~M* at z=6) become part of z=0 galaxy clusters. i-dropouts associated with protocluster regions are found in regions where the surface density is enhanced on scales ranging from a few to several tens of arcminutes on the sky. We analyze two structures of i-dropouts and Lya-emitters observed with the Subaru Telescope and show that these structures must be the seeds of massive clusters-in-formation. In striking contrast, six z~6 QSO fields observed with HST show no significant enhancements in their i-dropout number counts. With the present data, we cannot rule out the QSOs being hosted by the most massive halos. However, neither can we confirm this widely used assumption. We conclude by giving detailed recommendations for the interpretation and planning of observations by current and future ground- and space based instruments that will shed new light on questions related to the large-scale structure at z~6.

description: Formation of complex polyaniline (PANI) films with diamagnetic TCNQ and paramagnetic metal ion impurities cast under applied magnetic field was studied. It has been found that the applied magnetic field affects interaction of PANI chains with the impurities and induces formation of magnetically ordered regions in the complex film doped by paramagnetic metal ions in contrast to the reference film of the same composition but prepared under ambient conditions. The magnetically ordered regions have been observed directly by scanning magnetic force microscopy. It was found a correlation in distribution of the magnetically ordered regions and peculiarities of the surface relief of a film. Electronic absorption spectra and conductivity measurements showed that an applied stationary magnetic field can suppress the interaction of PANI chains and paramagnetic metal ions and lowers conductivity of the resulting complex film up to one order of magnitude as compared with the reference film. An alternating magnetic field was found to improve interaction of PANI and diamagnetic TCNQ molecules. The mechanisms of the magnetic field influence on the complex film formation are discussed.

Using cognitive cues to facilitate selective stopping of planned actions : a behavioural and physiological approach
Creators: name: Yaxley, EL
Publisher: name: University Of Tasmania
Year: 2023

description: Inhibitory control is the ability to cancel movements in response to changes in the environment (Band, Van Der Molen & Logan, 2003). The current study used behavioural and physiological measures to investigate selective inhibitory motor control, specifically whether prior cognitive knowledge, the type of prior knowledge presented, and hand dominance influenced stopping performance. Thirty-six participants aged between 18 to 36 years (`M`=24, `SD`=5.25) participated in a stop signal task, whereby they responded to visual 'go' signals with a bimanual button press and had to cancel (inhibit) one of the button presses on a small proportion of trials while continuing to execute the contralateral press. Electromyography (EMG) analysis was used to determine whether low levels of muscle activity were present on a correctly inhibited response (covert response). Behaviorally, prior cognitive knowledge reduced reaction time costs associated with selective stopping but did not abolish them. However, the type of knowledge presented, and hand dominance did not significantly reduce selective stop costs and stop signal reaction times. The EMG analysis suggests that the type of knowledge presented can impact inhibitory control, specifically depending on an individual's hand dominance. These findings build on previous research suggesting that prior cognitive knowledge can improve selective stopping abilities.

description: Lorentz transmission electron microscopy (LTEM) combined with in-situ magnetizing experiments is a powerful tool for the investigation of the magnetization of the reversal process at the micron scale. We have implemented this tool on a conventional transmission electron microscope (TEM) to study the exchange anisotropy of a polycrystalline Co35Fe65/NiMn bilayer. Semi-quantitative maps of the magnetic induction were obtained at different field values by the differential phase contrast (DPC) technique adapted for a TEM (SIDPC). The hysteresis loop of the bilayer has been calculated from the relative intensity of magnetic maps. The curve shows the appearance of an exchange-bias field reveals with two distinct reversal modes of the magnetization: the first path corresponds to a reversal by wall propagation when the applied field is parallel to the anisotropy direction whereas the second is a reversal by coherent rotation of magnetic moments when the field is applied antiparallel to unidirectional anisotropy direction.
The effects of snap decision making on episodic recognition memory
Creators: name: Hickey, E-JT
Publisher: name: University Of Tasmania
Year: 2023

description: The present study is interested in whether recognition memory errors made from snap decisions can be detected and corrected. Fifty two participants from the University of Tasmania made a two-stage recognition decision to words in a test list. The first decision, was a fast (<1sec) recognition memory (old/new) decision; the second a slower confidence response (high, low, change of mind). Words in the test list were manipulated for frequency (high, low), in the English language, and concreteness (high, low). Analysis of the change of mind responses showed an equal reduction from first response to second in the false alarm rate for both high frequency and low frequency words, and a significantly larger improvement in the hit rate for low frequency words from first response to second. Changed responses had a longer processing time (680ms) than unchanged responses (390ms). A significant word frequency mirror effect was also found, but not a significant word concreteness effect. The results indicate that participants can detect and correct errors made from quick decisions, and have important implications for the ability of decision making models' to predict correct responses, and for reducing the noise in speed-accuracy trade-off experiments (Rabbitt, 1969).

Measuring metacognition : the effects of framing and scale type on metacognitive accuracy
Creators: name: Breen, Rachel
Publisher: name: University Of Tasmania
Year: 2023

description: Accurate metacognitive judgements are necessary to predict the likelihood of recalling information and engage in effective learning. The study explored how manipulating JOL question frame and the scale of assessment affected metacognitive accuracy. Ninety-Two participants (59 female) aged 18-69 (`M` = 27.58, SD = 12.56) completed a cued-recall task of sixty-six English noun word-pairs and made JOLs. The method of JOL assessment (0-100% scale or binary task) and the frame of the JOL question (likelihood of remembering or forgetting) were manipulated to form four between-subjects conditions. The study-JOL-recall procedure was repeated to form two test cycles. Framing had a minimal impact on JOLs when measured on 0-100% scales. For binary conditions, the effects of framing differed depending on test cycle. It was concluded framing effects may result from the selection of different anchors, and that binary tasks may be more sensitive to framing. This study has implications for how health professional, educators, and researchers may consider assessing the beliefs about memory of those they teach. The study highlights the way assessments are made can influence the accuracy of metacognitive beliefs. Hence further research into and development of methods to accurately assess metacognition in both laboratory and real-world settings is necessary.

description: Com base nas potencialidades da comunicação interativa e descentralizada na Internet, a disponibilização crescente de espaços destinados aos comentários dos “leitores” na imprensa online tem suscitado o debate em torno do seu contributo para a inversão da tendência descendente, evidenciada pela atual sociedade, no exercício de uma cidadania ativa. Atendendo a este fenómeno, o presente artigo pretende analisar e discutir, adotando como referência a teoria deliberativa, as evidências desta possibilidade nos comentários feitos na secção de Educação pelos “leitores” do jornal Público.pt. Suportados em técnicas de análise de conteúdo a um corpus de 294 comentários referentes a 9 notícias da secção e jornal referidos, os resultados sugerem que embora os comentadores não tenham a intenção de alcançarem consenso no debate com os demais, estão interessados em expressar e partilhar as suas opiniões, argumentos e pontos de vista, mesmo que o façam sob anonimato. A análise aos comentários permitiu concluir que a deliberação que se verificou neste espaço do Público.pt assumiu um caráter essencialmente público e coletivo, na medida em que os comentadores debatem na esfera públicos problemas comuns, embora não se verifique a transformação das opiniões dos participantes no debate por força dos argumentos de outros que a deliberação pressupõe.

Vanity versus art : exploring the effects on Instagram self-presentation
Creators: name: Dolzan, RS
Publisher: name: University Of Tasmania

description: Instagram is a popular photo sharing application that enables users to present images, with the opportunity to strategically present themselves. This study examined the effects of personality traits on the congruency of individual's self-presentation on Instagram. Congruency of self-presentation is encouraged for positive effects on psychological well-being. The influence of exhibitionism, drive, social desirability, conformity, appreciation of beauty, grandiose and vulnerable narcissism were examined. 175 Instagram users, including both students and community members completed the anonymous online survey. The sample was predominantly female however, gender was found to have no effect on variables. Results of the regression analysis indicated that grandiose narcissism was a significant predictor of congruent self-presentation, whereas vulnerable narcissism and appreciation of beauty were significant predictors of decreased congruency. Results indicated exhibitionism, drive, conformity and social desirability did not influence self-presentation. Furthermore, grandiose and vulnerable narcissism were not significant moderators of the relationship between predictors and self-presentation. Content-based frequencies indicated a high percentage of users post to show and share images with an audience. Limitations of the study include self-report measures and cross-sectional design. Implications include identifying an alternative influence of artistic traits of Instagram users, and challenging the negative stereotyping of young Millennials and Instagram

description: The interpretation of some electrovacuum spacetimes in terms of counterrotating perfect fluid discs is presented. The interpretation is mades by means of an "inverse problem" approach used to obtain disc sources of known static solutions of the Einstein-Maxwell equations. In order to do such interpretation, a detailed study is presented of the counterrotating model (CRM) for generic electrovacuum static axially symmetric relativistic thin discs with nonzero radial pressure. Four simple families of models of counterrotating charged discs based on Chazy-Curzon-type, Zipoy-Voorhees-type, Bonnor-Sackfield-type, and charged and magnetized Darmois electrovacuum metrics are considered where we obtain some discs with a CRM well behaved.

description: Evolution of structure of spherical SiO2 nanoparticles upon cooling from the melt has been investigated via molecular-dynamics (MD) simulations under non-periodic boundary conditions (NPBC). We use the pair interatomic potentials which have weak Coulomb interaction and Morse type short-range interaction. The change in structure of SiO2 nanoparticles upon cooling process has been studied through the partial radial distribution functions (PRDFs), coordination number and bond-angle distributions at different temperatures. The core and surface structures of nanoparticles have been studied in details. Our results show significant temperature dependence of structure of nanoparticles. Moreover, temperature dependence of concentration of structural defects in nanoparticles upon cooling from the melt toward glassy state has been found and discussed.

Managing empire : Romano-Italic relations and the origins of the social war
Creators: name: Stewart, OJ
Publisher: name: University Of Tasmania
Year: 2023

description: Despite the importance of the Social War to events of Late Republican Rome much debate exists over the nature of the conflict itself. The conflict's origin as well as the motives of the combatants remains a topic of contention. This thesis uniquely considers the outbreak of the Social War in 91 BCE as a failure of Rome's alliance management. It proposes that tactics the Romans utilised to ensure the compliance of the Italian allies ceased to function effectively at the turn of the first century. By contrasting the Romans' approach to alliance management in the fourth and third centuries with that of the second, I argue that changes within the alliance gave rise to the possibility of conflict. To incentivise compliance in the earlier period, the Romans had secured the political and economic interests of the Italic communities. This incentive was not as potent in the later period. Instead, the Romans relied on deterrence against revolt, the other major component of their alliance management, to secure compliance. This is problematic for an alliance that relied heavily on cooperation. While this change occurred within the internal structure of the Italic alliances, I demonstrate that external factors were largely responsible. The addition of non-Italic communities to the alliance network and changes in domestic politics at Rome unsettled the foundations of the Italic alliances by altering the interests of both the Romans and the Italian allies. In this way, this study reveals the need for future research on the Social War to adopt a broad focus rather than treating the conflict as an isolated product of second century Italy.

description: We present a study of the extreme O-type supergiant He 3-759 using new high-resolution FEROS data, revealing that it is a near spectroscopic twin of HD 151804 (O8 Iaf). We investigate the extinction towards He 3-759 using a variety of methods, revealing A_V ~ 4.7 mag. If we assume He 3-759 has an identical absolute K-band magnitude to HD 151804 we find that it lies in the Sagittarius-Carina spiral arm at a distance of ~6.5 kpc. We derive the physical and wind properties for He 3-759, revealing T* = 30.5 kK, log L/L(sun) = 5.9 and dM/dt = 10^-5.17 M(sun)/yr for a clumped wind whose terminal velocity is estimated at 1000 km/s. The atmosphere of He 3-759 is enriched in helium (X_He = 49%) and nitrogen (X_N = 0.3%). A reanalysis of HD 151804 and HD 152408 (WN9ha) reveals similar parameters except that the WN9ha star possesses a stronger wind and reduced surface hydrogen content. HD 151804 and HD 152408 lie within the Sco OB1 association, with initial masses of ~60 M(sun) and ages ~2.7 Myr, consistent with NGC 6231 cluster members using standard Geneva isochrones. Improved agreement with observed surface abundances are obtained for similar initial masses with more recent Geneva group predictions from which higher ages of ~3.75 Myr are obtained. No young, massive star cluster is known to be associated with He 3-759.

Habituation of anxiety and cortical hypervigilance during image-based exposure
Creators: name: Williams, Monique
Publisher: name: University Of Tasmania

description: Habituation (decreased response to stimuli with repeated exposure) of attentional hypervigilance (preferential allocation of attention to feared stimuli) was investigated in specific fear. Participants with high (n=13) or low (n=13) spider fear passively viewed bird (neutral) images and progressively 'scarier' spider (fear-relevant) and snake (negative) images, in separate six-stage hierarchies. Stage six contained the image from Stage one repeated. Electrophysiological (EEG) activity was recorded throughout and the P1 event-related potential (ERP) was taken as a cortical measure of attentional hypervigilance. Participants rated their subjective anxiety (Subjective Units of Distress Scale; SUDS) at four timepoints for each stage (0, 30, 60, 90 seconds). Both groups showed reductions in P1 amplitude at Stage 3 compared to Stage 1 in the spider image hierarchy, and compared to Stages 1 and 2 in the snake image hierarchy. Both groups also demonstrated re-emergence of P1 amplitude at Stage 6 compared to Stage 3 of the spider and snake hierarchies. High but not low spider fear participants showed habituation of subjective anxiety within later spider image stages (4-6), but there was little evidence of habituation between stages. Together, findings do not provide evidence for a fear-specific neural mechanism during image-based exposure. Findings may otherwise reflect covert avoidance of, or dishabituation of visual attention towards, evolutionary threat images. It difficult to determine if participants attended to images given the use of a passive viewing paradigm and the graded task may have confounded arousal with habituation. Future research may employ eye-tracking technology and non-graded stimuli.
Behavioural and ERP correlates of hypervigilance and inhibitory control in spider fear

description: Attentional biases to threat are thought to arise from anxiety promoting automatic attentional processing in the form of hypervigilance, while disrupting voluntary attentional processes such as inhibitory control. There is little support for the latter in specific fear. The current study examined behavioural (RT and accuracy) and electrophysiological correlates of hypervigilance (P1 amplitude) and inhibitory control (N2 amplitude) in 15 high and 15 low spider fear females aged 18-40 years using a modified flanker go nogo task with increased cognitive load. Spider or flower go targets were flanked by incongruent images or neutral dashes. A central mushroom appeared on nogo trials, and could be flanked by either spider or flowers. High fears did not show faster RTs and greater P1 amplitude in response to spider targets as hypothesised, with both groups showing greater RTs to spider targets, and low fears demonstrating reduced P1 amplitude in the left hemisphere. Contrary to predictions, there was no fear-specific behavioural interference or reduced nogo-N2 amplitude in high fears, but they did show increased N2 amplitude on trials with spider flankers. This may suggest a compensatory inhibitory mechanism in response to feared stimuli. However, the current paradigm may not have adequately elicited automatic attentional processing or fear responses.

description: We analyzed the decays of $B^{+}\to {\bar {D}^0}+D^{+}_{sJ}(2S)$ and $B^{+}\to\bar D^{0}+D^{+}_{sJ}(1D)$ by naive factorization method and model dependent calculation based on the Bethe-Salpeter method, the branching ratios are $Br({\bar {D}^0}D^{+}_{sJ}(2S))=(0.72\pm0.12)%$ and $Br({\bar {D}^0}D^{+}_{sJ}(1D))=(0.027\pm0.007)%$. The branching ratio of decay $B^{+}\to {\bar {D}^0}D^{+}_{sJ}(2S)\to {\bar {D}^0}D^0 K^+$ consist with the data of Belle Collaboration, so we conclude that the new state $D^{+}_{sJ}(2700)$ is the first excited state $D^{+}_{sJ}(2S)$.

description: A maioria dos contextos de investigação nas ciências humanas e sociais está direta e indiretamente ligada às interações humanas. Estas interações podem ser realizadas em momentos síncronos ou assíncronos, sejam elas presenciais ou virtuais. Os registos dos momentos síncronos são tendencialmente mais espontâneos, imediatistas, pois em geral proporcionam pouco tempo para reflexão. Os registos assíncronos disponibilizam mais tempo e, portanto, mais oportunidades de reflexão sobre a informação prestada ao nível cognitivo, social e emocional. (...)

description: Asymptotic formulae for the mechanical and electric fields in a piezoelectric body with a small void are derived and justified. Such results are new and useful for applications in the field of design of smart materials. In this way the topological derivatives of shape functionals are obtained for piezoelectricity. The asymptotic formulae are given in terms of the so-called polarization tensors (matrices) which are determined by the integral characteristics of voids. The distinguished feature of the piezoelectricity boundary value problems under considerations is the absence of positive definiteness of an differential operator which is non self-adjoint. Two specific Gibbs' functionals of the problem are defined by the energy and the electric enthalpy. The topological derivatives are defined in different manners for each of the governing functionals. Actually, the topological derivative of the enthalpy functional is local i.e., defined by the pointwise values of the governing fields, in contrary to the energy functional and some other suitable shape functionals which admit non-local topological derivatives, i.e., depending on the whole problem data. An example with the weak interaction between mechanical and electric fields provides the explicit asymptotic expansions and can be directly used in numerical procedures of optimal design for smart materials.

description: Molecule-based devices are envisioned to complement silicon devices by providing new functions or already existing functions at a simpler process level and at a lower cost by virtue of their self-organization capabilities. Moreover, they are not bound to von Neuman architecture and this feature may open the way to other architectural paradigms. Neuromorphic electronics is one of them. Here we demonstrate a device made of molecules and nanoparticles, a nanoparticle organic memory filed-effect transistor (NOMFET), which exhibits the main behavior of a biological spiking synapse. Facilitating and depressing synaptic behaviors can be reproduced by the NOMFET and can be programmed. The synaptic plasticity for real time computing is evidenced and described by a simple model. These results open the way to rate coding utilization of the NOMFET in dynamical neuromorphic computing circuits.

Cadburys at Claremont : an antipodean Bournville?
Creators: name: Barton, Ruth
Publisher: name: University Of Tasmania

description: The Cadbury-Fry-Pascall Ltd (Cadbury) factory established at Claremont, Tasmania in 1921 was unique insofar as it involved the complete transfer of a British based company and management, with associated welfare and planning traditions, to a community of workers from a British cultural background living in Australia. A number of reasons can be put forward concerning the willingness of the Cadbury family as directors and managers, to implement identical welfare services in Tasmania. An examination is made of the principles, development and social consequences of these welfare services in order to arrive at historical and sociological explanations. These explanations are based upon considerations of four interrelated elements : the use of welfare as a means of gaining control over the workforce, the religious ideology of the Quaker owners, the Progressive ideas of the contemporary management and the attitudes of the Australian workers.
