Getting old and heading south: the academic success of Southerner learners in design cohorts

This paper investigates the relationship between learning style, as determined by Kolb's Learning Style Inventory, age and one measure of academic performance in design assignments for two cohorts of first- and third-year architecture students. The paper focuses on the results of a cross-curriculum learning style survey conducted as part of a project aimed at resolving the learning difficulties of students collaborating in multi-disciplinary and multi-cultural team assignments. The research was conducted to determine how learning style differences in heterogeneous teams might be addressed through pedagogy. In light of evidence in student cohorts of learning style changes towards the learning styles of design teachers as students progress through their studies, this paper demonstrates how these changes reflect a statistically significant relationship between learning styles and academic performance in design assignments.

Nestling testosterone is associated with begging behaviour and fledging success in the pied flycatcher, Ficedula hypoleuca

Animal signals are hypothesized to be costly in order to honestly reflect individual quality. Offspring solicitation signals given by nestling birds are thought to have evolved to advertise either need or individual quality. We tested the potential role of testosterone (T) in controlling the intensity of these signals by measuring begging behaviour as: (i) duration of the begging display and (ii) maximum height of the begging stretch, and by sampling endogenous T levels in nestling blood. We tested nestling pied flycatchers (Ficedula hypoleuca) using well-established experimental paradigm involving transient food deprivation to encourage begging behaviour and then blood-sampled nestlings at the end of these tests for T levels. Our results show that individual nestlings with the most intense begging displays had the highest circulating levels of T immediately after testing. In addition, we found substantial differences between broods in terms of circulating T. Finally, we found evidence that broods with higher levels of T showed increased fledging success, indicating a benefit for increased T production in nestlings. The potential trade-offs involved in T-mediated begging behaviour are discussed.

Understanding success in indigenous entrepreneurship : an exploratory investigation

In Canada there are numerous studies about indigenous Entrepreneurship, most descriptive with little theory development or testing, This leaves a gap in the information available to researchers, policy makers and practitioners. In this paper we describe a research program intended to address this gap beginning with the activities of the Lac La Ronge Indian Band, considered an exemplar of successful indigenous entrepreneurship. From these activities, we draw propositions about indigenous entrepreneurship that are compatible with generic theory. Finally, we describe how we will move from these propositions to a model of indigenous entrepreneurship using grounded theory and structural equation modelling.

Where do entrepreneurs have the best chances of success? The Asia-Pacific regulatory environment for entrepreneurial Micro And Medium Sized Enterprises (MMES)

Why do some entrepreneurs succeed while others fail in international competition? Perhaps it is better to turn the question around and ask, why is it that a particular country or economy becomes the home base for competitive globally-oriented entrepreneurs? What makes Australia a global leader in wine exports? How did New Zealand make it to global ranks in the creative industries? Why does Singapore have the most businessfriendly environment for entrepreneurs? Why is it “location, location, location”? One of the most powerful factors is the regulatory environment.

Asia-Pacific country-specific and region-specific regulations are diverse, and they seriously affect the climate for start-up entrepreneurs. They range from best-in-the world (e.g. Australia, New Zealand and Singapore) to the dreadful (Indonesia), according to the World Bank. Costs and profits can be affected as much by a government regulation as by a management decision. Fundamental entrepreneurial decisions--such as which lines of business to go into, which products and services to produce and introduce, which investments to finance, how and where to make goods and how to market them, and what prices to charge--are increasingly subject to governmental control.

In this short paper, we examine World Bank and Transparency International data on Asia-Pacific regulatory environments and make statements about how the economies compare to best practice. While I use data collected by other sources, I believe the added value comes through comparing and contrast the regulatory environments of our region in a justifiable and easily understood manner.

Measuring the success of intervention programmes designed to increase the participation rate by women in computing

Many intervention programmes to encourage greater female participation in computer education and careers have been conducted in the last twenty years. These intervention programmes take considerable time, effort and money to design and implement. If success were to be measured by an increase in the percentage of female students undertaking computing courses then these programmes would have to be considered a failure. This paper describes a research project which examined fourteen intervention programmes in detail. From the perspective of the programme champions each of the intervention programmes was considered successful, even when this success was restricted to specific areas or limited to small groups of individuals. Formal evaluation appeared to have been an afterthought rather than a priority of many of the programme champions. Some programmes appeared to be less effective due to the lack of targeted and clear goals or predetermined evaluation criteria. It is recommended that during the initial planning phase for intervention programmes a clear objective is to consider what a successful programme would look like and what the evaluation criteria would be. Further work is needed to understand how intervention programmes can be better designed and evaluated so that their impact and success can be expanded.

Iridescent structurally based coloration of eyespots correlates with mating success in the peacock

Gaudy plumage coloration is a widespread ornamental trait in birds and thought to be sexually selected. Although much attention has been devoted to structural coloration reflecting in UV, the signaling function of structural colors lacking UV reflectance and those that exhibit iridescence coloration are poorly documented. The train of the peacock (Pavo cristatus), a classical example of a sexually selected trait, is composed of iridescent structurally colored eyespots not reflecting in UV. Until today, the role played by the structural color of the eyespots in female mate choice has never been investigated using spectrometry. We measured eyespot coloration from a stationary angle (static coloration) and the change in coloration resulting from different angles (iridescent coloration). We assessed coloration with reflectance spectrometry, and we analyzed reflectance spectra using 2 methods. First, we extracted the reflectance spectra shape descriptors hue, brightness, and chroma. Second, we computed color and brightness contrasts signaled by eyespot feathers, taking peafowl color visual sensitivity into account. Iridescence was estimated by the maximal change for all parameters. Brightness was correlated with male mating success. The maximal change in color contrast was correlated with both the frequency of male visitation by females and male mating success. These results suggest that peahens can use both static and dynamic (i.e., iridescent) aspects of plumage structural coloration as signals to detect and choose their mates.

Factors affecting success in undergraduate computer programming

The aim of the research is to investigate factors that may explain success in elementary computer programming at the tertiary level. The first phase of the research included the identification of possible explanatory factors through a literature review, a survey of students studying introductory computing, a focus-group session with teachers of computer programming and interviews with programming students. The second phase of the research that was called the main study, involved testing the identified factors. Two different groups of programming students - one group majoring in business computing and another majoring in computer science - completed a survey questionnaire. The findings of the research are as follows. Gender is of little significance for business students but there is an adverse gender penalty for females in computer science. Secondary school assessment is inversely related to outcomes in business computing but directly influences outcomes in the first programming unit in the computer science course. As in prior research, previous knowledge and experience were demonstrated to matter, A range of other variables was found to be of little importance. The research suggests that different problem-solving techniques might be relevant in business compared with those of use in computer science.

Male and female effects on fertilization success and offspring viability in the Peron's tree frog, Litoria peronii

There is increasing theoretical and empirical evidence that genetic compatibility among partners is an important determinant of fertilization success and offspring viability. In amphibians, females often actively choose partners from among a variety of males and polyandry is common. Genetic compatibility among partners may therefore be an important determinant of fertilization success and offspring viability in some amphibians. Amphibians also show some of the highest levels of genetic differentiation among neighbouring populations known in vertebrates, and as such, populations may have evolved different co-adapted gene complexes. This means that offspring from among-population crosses may have reduced fitness. It is therefore essential to understand to what extent crossings between and within populations may interfere with successful fertilization and offspring viability. Here, we test whether crossing individuals within and between two different populations of the Australian Peron's tree frog (Litoria peronii) using artificial fertilizations affect fertilization success and offspring viability. Fertilization success per se is strongly influenced by male identity, which is likely to depend at least to some extent on the experimental procedure (e.g. resulting in variation in sperm number per ejaculate), whereas there was no fertilization effect of female identity. More importantly, male and female identity, independently of each other, explained significant variation in offspring viability, whereas no such effect could be linked to population of origin. Thus, our experiments suggest that crossing populations may not always be the most significant factor affecting fertilization success or offspring viability, but may be more influenced by the genetic quality or the genetic compatibility of partners.

A stochastic derivation of the ratio form of contest success functions

This note provides a distribution-based justification for the ratio form of contest success functions (CSFs), in which a player’s success depends positively on her effort relative to that of her opponents. I show that the inverse exponential distribution of the random shocks yields the ratio form. Extending this approach to asymmetric contests, I also derive an asymmetric ratio form of CSFs.
