Moral decision making
Creators: name: Reid, EM
Publisher: name: University Of Tasmania
Year: 2023

description: The present study investigated the underlying process of moral decision making, by comparing two prominent theories, and factors that can moderate this. The dual process model suggests cognitive load will selectively reduce utilitarian inclinations (as both the decision and increased cognitive load use cognitive resources), whilst having no effect on deontological inclinations; the Social Intuitionist Model stipulates cognitive load will have no effect on either. The more people saved (for the same number killed; efficient ratio) the more utilitarian the response should be. Method: One hundred and sixty-six participants (125 females; aged 18-73 years, 40 males; aged 19 to 68, and one 24-year-old who did not identify as either) were allocated into one of four conditions, manipulating both cognitive load and kill/save ratio (KSR). Participants remembered a digit string (easy or hard depending on condition) whilst answering a moral dilemma and then answered questions about the difficulty, of the questions and memory task, and some demographics. Results: Bayesian analysis provide some evidence in favour of the null hypothesis for an effect of cognitive load; thus, there is no effect ‚Äö- supporting the Social Intuitionist Model. There is definitive evidence suggesting there is an effect of KSR consistent with theory. Conclusion: Results suggest social and cultural influences determine one's moral principles, and thus cognitive load will have no effect on the decision. KSR has an impact to an extent; however, some individual differences make it impossible to ever be utilitarian. Future research should look at more individual differences and populations to determine if findings are the same.

description: Multiprocessors have emerged as a powerful computing means for running realtime applications, especially where a uniprocessor system would not be sufficient enough to execute all the tasks. The high performance and reliability of multiprocessors have made them a powerful computing resource. Such computing environment requires an efficient algorithm to determine when and on which processor a given task should execute. In multiprocessor systems, an efficient scheduling of a parallel program onto the processors that minimizes the entire execution time is vital for achieving a high performance. This scheduling problem is known to be NPHard. In multiprocessor scheduling problem, a given program is to be scheduled in a given multiprocessor system such that the programs execution time is minimized. The last job must be completed as early as possible. Genetic algorithm (GA) is one of the widely used techniques for constrained optimization problems. Genetic algorithms are basically search algorithms based on the mechanics of natural selection and natural genesis. The main goal behind research on genetic algorithms is robustness i.e. balance between efficiency and efficacy. This paper proposes Genetic algorithm to solve scheduling problem of multiprocessors that minimizes the make span.

Mental health service use among people with cancer, anxiety, and depression : analysis of the Australian national health survey
Creators: name: Richardson, Emma
Publisher: name: University Of Tasmania
Year: 2023

description: `Objectives:` Access to mental health services for people with co-morbid cancer and anxiety/depression are an essential component of comprehensive quality care. The present study explored differences in mental health service use among people with and without cancer and/or anxiety/depression in Australia, as well as associations between health service use and health and sociodemographic characteristics. `Methods:` Data from 14,560 adults was obtained from the 2014-15 Australian National Health Survey (NHS). Participants were categorised as having no cancer nor anxiety/depression, cancer only, anxiety/depression only, or both cancer and anxiety/depression. Across these groups, GP, specialist, and mental health use was compared, with analyses to identify the sociodemographic and health characteristics associated with each groups health service use also completed. \\(Results:\\) GP, specialist, and mental health service use was significantly greater among those with cancer, anxiety/depression, and both cancer and anxiety/depression, than those with no cancer or anxiety/depression. More specifically, although mental health service use was greatest among those with cancer and anxiety/depression, the addition of cancer made little difference to the amount of access when compared to those with anxiety/depression only. Mental health service use was significantly lower among males and those with better self-rated health, and became less likely as people aged. `Conclusion:` Increased access to mental health services for people with cancer and anxiety/depression is required, particularly for males, older adults, and those at social and economic disadvantage. To increase referrals and uptake of mental health services, education for both health professionals and people with cancer and/or anxiety/depression, along with the creation of more accessible services, is essential.

description: The probability distribution functions (PDFs) of momentum flux and zonal flow formation in ion-temperature-gradient (ITG) turbulence are investigated, including the effect of the shear flow on the PDFs. While ITG turbulence maintains high level of transport, this may be suppressed by shear flow. Zonal flows are also shown here to have an enhanced likelihood of generation further from marginal stability which will then regulate the ITG turbulence, which is more prominent with increased shear flow, leading to a self-regulating system.

description: In this paper the behavior of three combinational rules for temporal/sequential attribute data fusion for target type estimation are analyzed. The comparative analysis is based on: Dempster's fusion rule proposed in Dempster-Shafer Theory; Proportional Conflict Redistribution rule no. 5 (PCR5), proposed in Dezert-Smarandache Theory and one alternative class fusion rule, connecting the combination rules for information fusion with particular fuzzy operators, focusing on the t-norm based Conjunctive rule as an analog of the ordinary conjunctive rule and t-conorm based Disjunctive rule as an analog of the ordinary disjunctive rule. The way how different t-conorms and t-norms functions within TCN fusion rule influence over target type estimation performance is studied and estimated.

The attitude and achievement of tenth grade general mathematics students as effected by the use of desk calculators
Creators: name: Humphries, Leslie Rae
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of the study was to determine whether the use of a desk calculator in a grade ten general mathematics class would produce a positive change in a pupil’s attitude toward mathematics, to see if achievement in quantitative thinking (problem solving) would be increased, and to see if there was a correlation between any such changes. Two teachers, each having two classes of grade ten general mathematics, taught an experimental and a control class. The experimental classes were instructed in the use of desk calculators, and encouraged to use the calculators to arrive at solutions to a prearranged program in mathematics. The control groups were taught in a similar manner, but did not have access to desk calculators. The classes were pre-tested and post-tested for attitude and achievement. A Mathematics Attitude Test was constructed which yields (1) a "Preference for Calculation" score, (2) a "Preference for Quantitative Thinking" (Problem Solving) score, and (3) a composite "Mathematics Attitude" score. The test comprised sixteen three-part situations consisting of (A), a calculation situation, (B), a quantitative thinking (problem solving) situation, and a distracter, (C), a non-mathematical activity. The pupils were asked to state a like and a dislike among the three offered. On item analysis using biserial r, all but one of the items proved satisfactory. When using the Spearman-Brown prophecy formula for estimating reliability, the reliability was found to be sufficient for differentiating between means of groups, but not sufficient for differentiation of individual differences. Analysis of Covariance was used to compare the groups for a significant positive change in attitude, and also for a significant improvement in achievement. The correlation of a suspected positive change in attitude and improvement in achievement was checked for significance. At the 0.05 level, there was no significant change in attitude and no significant change in achievement. At the 0.08 level, however, there was a significant improvement in achievement. There was no significant correlation of a positive change in attitude and improvement in achievement. The conclusion drawn was that the use of a desk calculator makes no significant change in attitude, but perhaps might change achievement with a carefully planned program. No correlation of a positive change in attitude and achievement was found. The attitude test constructed may, with modifications, be of use to other experimenters.

Helping those who help us : examining the effect of mental training programs on resilience in first responders
Creators: name: Connolly, CE
Publisher: name: University Of Tasmania
Year: 2023

description: First responders are exposed to significant physical, psychological and social stressors and present with higher levels of negative outcomes such as depression, anxiety and post-traumatic stress than the general population. Therefore, identifying predictors of health is paramount to preserve their wellbeing. This research implemented two brief mental training programs (mindfulness and self-reflection training) and examined their effect on psychological outcomes. A sample of police officers and state emergency service personnel (N=18) completed a baseline survey measuring resilience, depression, anxiety, job satisfaction and mindfulness. Participants were randomly allocated to a mindfulness or self-reflection group and completed mental trainings over a four-week period. Six participants completed a follow-up survey with no significant differences found between pre and post-training measures of resilience, anxiety, job satisfaction or mindfulness. There was a main effect of time on depression, suggesting that engaging in mental training was effective in reducing depressive symptoms irrespective of the training type. The results of this study suggest a role for mental training programs in improving depressive symptoms, and demonstrate the need for tailored interventions to be developed that overcome the unique practical and cultural barriers faced by first responders that may otherwise impede optimal enhance mental health and wellbeing outcomes.

description: Personalized recommender systems are confronting great challenges of accuracy, diversification and novelty, especially when the data set is sparse and lacks accessorial information, such as user profiles, item attributes and explicit ratings. Collaborative tags contain rich information about personalized preferences and item contents, and are therefore potential to help in providing better recommendations. In this paper, we propose a recommendation algorithm based on an integrated diffusion on user-item-tag tripartite graphs. We use three benchmark data sets, Del.icio.us, MovieLens and BibSonomy, to evaluate our algorithm. Experimental results demonstrate that the usage of tag information can significantly improve accuracy, diversification and novelty of recommendations.

Benny or Benno? : Our Aussie lingo
Creators: name: Davie, HR
Publisher: name: University Of Tasmania
Year: 2023

description: Hypocoristics are informal variations of words which are common in Australian English, such as footy for football. The aim of this study was to examine whether people used different hypocoristics to convey different meanings for novel words (as common nouns, place names, male names, and female names), when presented as either 'loveable' or 'unloveable'. Our sample consisted of 132 adults living in Australia (66% female, mean age 25 years), who completed this study online. In line with the as-yet untested predictions of McAndrew (1992), it was hypothesised that participants would apply significantly more -ie endings to loveable than unloveable words, and significantly more -o endings to unloveable than loveable words. Both hypotheses were supported. Our results further supported the prediction that participants would add significantly more -o endings to male than female names, but not the prediction that they would add significantly more -ie endings to female than male names: in fact, the use of -ie did not differ. Changes made to individual word types, and to word length, are also discussed in a more exploratory manner. Overall, the results suggest that Australian adults create hypocoristics not randomly, but in a systematic way, to convey different meanings.
'Ultimate' Information Content in Solar and Stellar Spectra: Photospheric line asymmetries and wavelength shifts
Creators: name: Dravins, Dainis
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: CONTEXT: Spectral-line asymmetries and wavelength shifts are signatures of hydrodynamics in solar and stellar atmospheres. Theory may precisely predict idealized lines, but observed spectra are limited by blends, too few suitable lines, imprecise laboratory wavelengths, and by instrumental imperfections. AIMS: Bisectors and shifts are extracted until the 'ultimate' accuracy limits in highest-quality solar and stellar spectra, to understand limits set by stellar physics, observational techniques, and limitations in laboratory data. METHODS: Spectral atlases of the Sun and bright solar-type stars were examined for thousands of 'unblended' lines with the most accurate laboratory wavelengths, yielding bisectors and shifts as averages over groups of similar lines, thus minimizing effects of photometric noise and of random blends. RESULTS: For solar spectra, bisector shapes and shifts were extracted for previously little-studied species (Fe II, Ti I, Ti II, Cr II, Ca I, C I), using recently determined very accurate laboratory wavelengths. In Procyon and other F-type stars, a blueward bend in the bisector near the spectral continuum reveals line saturation and damping wings in upward-moving photospheric granules. Accuracy limits set by 'astrophysical' noise, finite instrumental resolution, superposed telluric absorption, and inaccurate wavelengths, together limit absolute lineshift studies to approximately 50-100 m/s. CONCLUSIONS: Spectroscopy with resolutions R = 300,000 will enable bisector studies for many stars. Circumventing remaining limits of astrophysical noise in line-blends and rotationally smeared profiles may ultimately require spectroscopy across spatially resolved stellar disks.

description: Over the last few decades, the high velocity oxygen fuel (HVOF) spraying of WC-CoCr for internal diameter (ID) coating has attracted much interest for hard chrome replacement. Current demands for the ID coating of small cylindrical parts necessitates the use of specialized spray gun equipment and powder feedstocks with small particle size fractions. Due to the limited spray distance inside cylindrical parts with small IDs, the process control, spraying fine WC-CoCr powders, meets new challenges to avoid significant WC decomposition, which increases the risk of mechanical degradation. Within the scope of this study, ID-HVOF spraying using a fine-structured WC-CoCr (−15 + 5 μm) feedstock with a mean WC particle size of 400 nm is examined with respect to the WC decomposition phenomena using X-ray diffraction (XRD). Hence, a statistical design of experiments (DoE) is utilized to systematically analyze various spray parameter settings along with their interaction as part of the WC to W2C conversion.

description: Postsecondary mathematics classrooms continue to become more diverse, which implores educators to continue to incorporate more diverse modes of assessment to support all learners. However, researchers have found that mathematics assessment at the postsecondary level has remained mostly stagnant, with traditional, closed-book exams dominating the field. In this paper, we present three alternative forms of mathematics assessments for teachers at the postsecondary level. We incorporate researched-based tools for implementation and grading online, oral, and project-based assessments in mathematics. Potential limitations of each type of assessment are also addressed

The Mathematical Mindsets and Mathematical Identities Revealed in Social Media Discourse
Creators: name: Barba, Kimberly
Publisher: name: Journal of Mathematics Education at Teachers College
Year: 2021

description: Mathematics problems are shared rapidly across all social media platforms, and the relative anonymity granted to users can lead to unfiltered discourse. This study examined 1,046 comments from a mathematics problem posted twice to YouTube in February 2016 to determine the underlying narratives that indicate the commenters’ mathematical mindsets and their mathematical identities. These two factors contribute to mathematics success in general. Qualitative themes emerged regarding attributions, motivational goals, response to failure, defensive processing, normative comparisons, and positional acts. A fixed mathematical mindset was the dominant mindset and corresponded to positional acts of superiority, inferiority, or authority. This finding suggests that intellectual capacity or ranking was a core component of the mathematical identities for these users. The growth mathematical mindset was linked to spectator and instructor or solidarity positions, suggesting that these users had more robust mathematical identities that were unthreatened by performance indicators. Further examination of social media discourse and its relation to mathematical mindsets and mathematical identities can lead to a better understanding of the interactions outside the classroom that either encourage or inhibit mathematics success.

Conceptualizing Student Responsibilities in Discourse-Rich Classrooms

Publisher: name: Journal of Mathematics Education at Teachers College
Year: 2021

description: While a growing body of research examines teachers’ facilitation of discourse-rich classrooms, surprisingly little research is devoted to learners’ responsibilities in such classrooms. In this paper, we share a theoretical model for explaining students’ responsibilities in yielding mathematical learning in discourse-rich classrooms. These responsibilities consist of the following: (1) determined listening and striving to understand others’ contributions; (2) proactive contribution; (3) maintaining equal positioning; (4) willingness to resolve incommensurability; and (5) on-task talk. Each of the responsibilities is interdependent, suggesting that failure to meet one responsibility decreases the likelihood that another responsibility will be met. The model suggests important implications for supporting learners in discourse-rich classrooms.

description: The relative roles of metallicity and surface gravity on the near-infrared spectra of late-T brown dwarfs are not yet fully understood, and evolutionary models still need to be calibrated in order to provide accurate estimates of brown dwarf physical parameters from measured spectra. The T-type brown dwarfs Eps Indi Ba and Bb forming the tightly bound binary Eps Indi B, which orbits the K4V star Eps Indi A, are nowadays the only such benchmark T dwarfs for which all important physical parameters such as metallicity, age and mass are (or soon will be) known. We present spatially resolved VLT/NACO images and low resolution spectra of Eps Indi B in the J, H and K near-infrared bands. The spectral types of Eps Indi Ba and Bb are determined by direct comparison of the flux-calibrated JHK spectra with T dwarf standard template spectra and also by NIR spectral indices. Eps Indi Bb is confirmed as a T6 while the spectral type of Eps Indi Ba is T1.5 so somewhat later than the previously reported T1. Constrained values for surface gravity and effective temperature are derived by comparison with model spectra. The evolutionary models predict masses around about 53 M_J for Eps Indi Ba and about 34 M_J for Eps Indi Bb, slightly higher than previously reported values. The suppressed J-band and enhanced K-band flux of Eps Indi Ba indicates that a noticeable cloud layer is still present in a T1.5 dwarf while no clouds are needed to model the spectrum of Eps Indi Bb.

description: The non-learning of school mathematics is now almost universally taken for granted, but this does not have to happen. This article takes a critical look at the root of this non-learning by pointing to the flagrant defects in the kind of mathematics—to be called TSM—that is predominant in almost all the school textbooks. By analyzing how the long division algorithm is taught and why it becomes so mystifying to school students, we explore how to provide the missing reasoning that makes sense of the algorithm. The article also suggests some concrete steps we can take to eradicate TSM.

The effects of selective feedback on visual search target detection
Creators: name: de Haan, A
Publisher: name: University Of Tasmania
Year: 2023

description: The current study investigated the effect of a retraining intervention that utilises selective feedback, in which feedback is only provided for misses, on target detection performance in low prevalence settings. Fifty-one participants (34 female) aged 18-50 years (M =26.57 years, SD =6.19 years) were randomly allocated to either the control condition, where they received no feedback, the full feedback condition, where they received feedback on all training trials, or the selective feedback condition, where they only received feedback when they missed a target on a training trial. Participants completed a visual search task that required them to look for a knife in x-ray images of luggage. The study consisted of alternating long, low prevalence 'on the job' blocks and brief, higher prevalence 'training' blocks. As expected, the selective feedback retraining procedure led to a significantly less conservative criterion than full feedback and no feedback. This translated into a significantly greater proportion of false alarms than full feedback and no feedback, and a meaningful, but non-significant, increase in hits compared to the control condition. Unexpectedly, however, there was no effect of feedback on response times. Such findings provide valuable information for the low prevalence setting of airport luggage screening.
An ecological framework for regional agricultural development planning in west africa.
Creators: name: Yirenkyi, Emmanuel Ayeh
Publisher: name: University of British Columbia
Year: 2011

description: Agricultural development involves the large scale economic production of plant and animal crops through modification and exploitation of ecosystems. Since crop species themselves are integral parts of the ecosystemic complex, any effort to raise the productivity of tropical agriculture must acknowledge ecological constraints as well as the opportunities for improved production. In the tropics this fundamental principle has been overlooked in the reduction of diversity of the ecosystem through monoculture of a very few export crops. In addition to reducing ecosystemic stability this has led to reduced production of basic food staples. The rich fauna is being replaced by domestic cattle, sheep, goats, pigs and poultry. Monoculture has led to the adoption techniques requiring a large energy subsidy, i.e. selective breeding programmes, fertilization, mechanization and irrigation. Although the approach has proved conceptually sound in temperate regions and results in some practical benefits in the tropics, it has had a disastrous impact on the socio-economic stability of the traditional society. Undernourishment, poverty and the social unrest which have characterised Ghana in recent past are inevitable consequences of the mismanagement of agriculture. The underlying hypothesis of the study is that the development of tropical agriculture within an ecologically sound framework is a fundamental pre-requisite to modernizing the system, to increasing productivity and to providing a sound basis for agricultural development planning in West Africa. Properly implemented it would safeguard the future of tropical agriculture and the environment. This study is based on an examination of available literature, information from a mailed questionnaire and personal familiarity with the study area. Since most of the data refer to Ghana, I have focussed on the Ghanaian situation while drawing on experience from elsewhere. An ecological approach to tropical agricultural development is described, followed by a comparative study of systems of production in the tropical and temperate zones. This permits an assessment of the impact of the "Green Revolution" on tropical agrarian systems and reforms. The consequences of mismanagement of tropical agricultural development are assessed with respect to socio-economic and political difficulties. Most of the source data support the hypothesis. Suggestions are made to redress the underlying causes of low tropical agricultural production. It is the conclusion of this thesis that tropical agriculture can be best developed by recognising the nature of tropical ecosystems.

description: An improved image mining technique for brain tumor classification using pruned association rule with MARI algorithm is presented in this paper. The method proposed makes use of association rule mining technique to classify the CT scan brain images into three categories namely normal, benign and malign. It combines the low level features extracted from images and high level knowledge from specialists. The developed algorithm can assist the physicians for efficient classification with multiple keywords per image to improve the accuracy. The experimental result on prediagnosed database of brain images showed 96 percent and 93 percent sensitivity and accuracy respectively.

The effect of siRNA-mediated Shank3 knockdown on Immunocytochemistry staining and motility in dorsal root ganglia growth cones
Creators: name: Healey, R
Publisher: name: University Of Tasmania
Year: 2023

description: Mutations of the Shank3 gene have consistently been identified as a risk factor for Autism Spectrum Disorder, and are associated with neurological abnormalities indicative of neural connectivity issues. This project aimed to elucidate the functions of Shank3 protein in the growth cone during neural development. It was hypothesised that in dorsal root ganglia growth cones, Shank would colocalise with Homer1b/c (a protein that regulates intracellular calcium responses to BDNF), that siRNA-mediated knockdown of Shank3 protein would reduce Shank expression, and that Shank3 knockdown would abolish growth cone turning responses to BDNF. Shank and Homer appeared to colocalise in the growth cone. However, Shank3 knockdown did not decrease protein expression, and cell culture issues required that turning assays be terminated. As such, this research infers a role of Shank protein in peripheral nervous development but is unable to clarify the specific implications of this for axon pathfinding. Directions for future research include addressing cell culture issues, and repeating knockdown and turning experiments on hippocampal cells known to express Shank3 in the growth cone.

description: We consider quarkonium in a hot QCD plasma which, due to expansion and non-zero viscosity, exhibits a local anisotropy in momentum space. At short distances the heavy-quark potential is known at tree level from the hard-thermal loop resummed gluon propagator in anisotropic perturbative QCD. The potential at long distances is modeled as a QCD string which is screened at the same scale as the Coulomb field. At asymptotic separation the potential energy is non-zero and inversely proportional to the temperature. We obtain numerical solutions of the three-dimensional Schroedinger equation for this potential. We find that quarkonium binding is stronger at non-vanishing viscosity and expansion rate, and that the anisotropy leads to polarization of the P-wave states.

title: Decontextualizing Development: A Critical Examination of American Popular Discourse on Foreign Aid
Creators: name: Haines, Jeffrey
Publisher: name: Old Dominion University Libraries
Year: 2011

description: Humanitarian foreign aid is a controversial topic, subject to much popular debate. Although there is much available polling and survey evidence about public stances on the issue, there have been significantly fewer attempts at more in-depth analyses of the public discourse. This thesis is an attempt to explore the popular discourse on aid in more depth, including its rationales, assumptions, and values.

It concludes that both sides of the American public in the debate often make use of similar types of assumptions regarding international affairs, suggesting often deeper agreement than the debate may indicate. It is argued that the set of assumptions that both sides appeal to is problematic, and a more adequate understanding of global interactions is provided by examining first world actions and policies that harm developing countries. Acknowledging these harms helps to establish a critical view of the discourse and provides a justification for foreign aid as compensation, a view that is not traditionally dominant.
Guidance document for WGS-Benchmarking

description: Whole genome sequencing (WGS) is increasingly used in diagnostics and surveillance of pathogenic microorganisms. Common applications for WGS is to use the data for the identification of pathogenic bacteria, antimicrobial resistance (AMR), virulence gene detection and during outbreak investigations. This guidance document presents how to benchmark the different WGS steps. A checklist was drafted for bacterial genome analysis using WGS technology that sets standards for the analytical wet lab (bench) process and bioinformatics analyses, also called "dry lab (bench)". In other words, bacterial WGS includes 2 steps:

Analytical wet lab analyses;
Bioinformatics analyses of reads obtained from sequencing.
The wet bench component generally includes any or all of the following steps: handling of isolates, DNA extraction, DNA fragmentation, barcoding (molecular indexing) of DNA fragments, enrichment of gene targets within certain panels, adapter ligation, amplification, library preparation, flow cell loading, and generation of sequence reads. Generation of reads is almost entirely automated and the output consists of millions to billions of short sequences (reads). The following dry bench workflow consists in intensive computational and bioinformatics analyses that use a variety of algorithms that, for instance, (i) map and align the short reads to a linear reference bacterial genome and/or (ii) perform de novo assembly.
The EURLs WG on NGS approached the analytic wet bench process and the bioinformatics analyses (''dry bench'') as two discrete processes requiring separate considerations for standards.
The EURLs WG have shared a survey to their NRLs network to ask them for different parameters used in the wet and dry lab part of WGS in their laboratories. These parameters are used in this guidance to present the different steps of WGS.

description: Due to its unique long-term coverage and high photometric precision, observations from the Kepler asteroseismic investigation will provide us with the possibility to sound stellar cycles in a number of solar-type stars with asteroseismology. By comparing these measurements with conventional ground-based chromospheric activity measurements we might be able to increase our understanding of the relation between the chromospheric changes and the changes in the eigenmodes. In parallel with the Kepler observations we have therefore started a programme at the Nordic Optical Telescope to observe and monitor chromospheric activity in the stars that are most likely to be selected for observations for the whole satellite mission. The ground-based observations presented here can be used both to guide the selection of the special Kepler targets and as the first step in a monitoring programme for stellar cycles. Also, the chromospheric activity measurements obtained from the ground-based observations can be compared with stellar parameters such as ages and rotation in order to improve stellar evolution models.

Secular Evolution in Disk Galaxies: Pseudobulge Growth and the Formation of Spheroidal Galaxies

description: Updating Kormendy & Kennicutt (2004, ARAA, 42, 603), we review internal secular evolution of galaxy disks. One consequence is the growth of pseudobulges that often are mistaken for true (merger-built) bulges. Many pseudobulges are recognizable as cold, rapidly rotating, disky structures. Bulges have Sersic function brightness profiles with index n > 2; most pseudobulges have n <= 2. Recognition of pseudobulges makes the biggest problem with cold dark matter galaxy formation more acute: How can hierarchical clustering make so many pure disk galaxies with no evidence for merger-built bulges? E. g., the giant Scd galaxies M101 and NGC 6946 have rotation velocities of V ~ 200 km/s but nuclear star clusters with velocity dispersions of 25 to 40 km/s. Within 8 Mpc of us, 11 of 19 galaxies with V > 150 km/s show no evidence for a classical bulge, while only 7 are ellipticals or have classical bulges. It is hard to understand how bulgeless galaxies could form as the quiescent tail of a distribution of merger histories. Our second theme is environmental secular evolution. We confirm that spheroidal galaxies have fundamental plane (FP) correlations that are almost perpendicular to those for bulges and ellipticals. Spheroidals are not dwarf ellipticals. Rather, their structural parameters are similar to those of late-type galaxies. We suggest that spheroidals are defunct late-type galaxies transformed by internal processes such as supernova-driven gas ejection and environmental processes such as secular harassment and ram-pressure stripping. Minus spheroidals, the FP of ellipticals and bulges has small scatter. With respect to these, pseudobulges are larger and less dense.
