Bat species comparisons based on external morphology: A test of traditional versus geometric morphometric approaches

External morphology is commonly used to identify bats as well as to investigate flight and foraging behavior, typically relying on simple length and area measures or ratios. However, geometric morphometrics is increasingly used in the biological sciences to analyse variation in shape and discriminate among species and populations. Here we compare the ability of traditional versus geometric morphometric methods in discriminating between closely related bat species – in this case European horseshoe bats (Rhinolophidae, Chiroptera) – based on morphology of the wing, body and tail. In addition to comparing morphometric methods, we used geometric morphometrics to detect interspecies differences as shape changes. Geometric morphometrics yielded improved species discrimination relative to traditional methods. The predicted shape for the variation along the between group principal components revealed that the largest differences between species lay in the extent to which the wing reaches in the direction of the head. This strong trend in interspecific shape variation is associated with size, which we interpret as an evolutionary allometry pattern.

Overview of design concepts of traditional Iranian architecture and its reflections in Iranian contemporary architecture

This article has attempted to investigate the patterns of traditional architecture in Iran's warm and dry climate and whether these patterns have been attended to in Iran's contemporary architecture or not. Since the two elements of culture and climate are much significant in Iran's traditional constructions, this article aimed at dealing with subjects such as the causes of the shapes of traditional buildings in Iran's warm and dry climate in constructions like houses, schools, mosques and bazaars, and why they were constructed in those shapes, and also considering their patterns in these places in the light of cultural and climatic aspects, and their cultural and climatic relationships and investigating cultural-climatic causes of the directions and situations designed for the spaces present in these buildings and finally it is intended to classify the conceptual patterns of the traditional architecture of Iran's warm and dry climate. The article is going to consider the amount of using these patterns in Iran's contemporary architecture. The study has been conducted using library and field method.

Maternal pregravid body mass index and child hospital admissions in the first 5 years of life: results from an Australian birth cohort

Objectives: To examine the association of maternal pregravid body mass index (BMI) and child offspring, all-cause hospitalisations in the first 5 years of life. Methods: Prospective birth cohort study. From 2006 to 2011, 2779 pregnant women (2807 children) were enrolled in the Environments for Healthy Living: Griffith birth cohort study in South-East Queensland, Australia. Hospital delivery record and self-report baseline survey of maternal, household and demographic factors during pregnancy were linked to the Queensland Hospital Admitted Patients Data Collection from 1 November 2006 to 30 June 2012, for child admissions. Maternal pregravid BMI was classified as underweight (<18.5 kg m−2), normal weight (18.5–24.9 kg m−2), overweight (25.0–29.9 kg m−2) or obese (30 kg m−2). Main outcomes were the total number of child hospital admissions and ICD-10-AM diagnostic groupings in the first 5 years of life. Negative binomial regression models were calculated, adjusting for follow-up duration, demographic and health factors. The cohort comprised 8397.9 person years (PYs) follow-up. Results: Children of mothers who were classified as obese had an increased risk of all-cause hospital admissions in the first 5 years of life than the children of mothers with a normal BMI (adjusted rate ratio (RR) =1.48, 95% confidence interval 1.10–1.98). Conditions of the nervous system, infections, metabolic conditions, perinatal conditions, injuries and respiratory conditions were excessive, in both absolute and relative terms, for children of obese mothers, with RRs ranging from 1.3–4.0 (PYs adjusted). Children of mothers who were underweight were 1.8 times more likely to sustain an injury or poisoning than children of normal-weight mothers (PYs adjusted). Conclusion: Results suggest that if the intergenerational impact of maternal obesity (and similarly issues related to underweight) could be addressed, a significant reduction in child health care use, costs and public health burden would be likely.

On the interaction between radon progeny and particles generated by electronic and traditional cigarettes

During their entire lives, people are exposed to the pollutants present in indoor air. Recently, Electronic Nicotine Delivery Systems, mainly known as electronic cigarettes, have been widely commercialized: they deliver particles into the lungs of the users but a “second-hand smoke” has yet to be associated to this indoor source. On the other hand, the naturally-occurring radioactive gas, i.e. radon, represents a significant risk for lung cancer, and the cumulative action of these two agents could be worse than the agents separately would. In order to deepen the interaction between radon progeny and second-hand aerosol from different types of cigarettes, a designed experimental study was carried out by generating aerosol from e-cigarette vaping as well as from second-hand traditional smoke inside a walk-in radon chamber at the National Institute of Ionizing Radiation Metrology (INMRI) of Italy. In this chamber, the radon present in air comes naturally from the floor and ambient conditions are controlled. To characterize the sidestream smoke emitted by cigarettes, condensation particle counters and scanning mobility particle sizer were used. Radon concentration in the air was measured through an Alphaguard ionization chamber, whereas the measurement of radon decay product in the air was performed with the Tracelab BWLM Plus-2S Radon daughter Monitor. It was found an increase of the Potential Alpha-Energy Concentration (PAEC) due to the radon decay products attached to aerosol for higher particle number concentrations. This varied from 7.47 ± 0.34 MeV L−1 to 12.6 ± 0.26 MeV L−1 (69%) for the e-cigarette. In the case of traditional cigarette and at the same radon concentration, the increase was from 14.1 ± 0.43 MeV L−1 to 18.6 ± 0.19 MeV L−1 (31%). The equilibrium factor increases, varying from 23.4% ± 1.11% to 29.5% ± 0.26% and from 30.9% ± 1.0% to 38.1 ± 0.88 for the e-cigarette and traditional cigarette, respectively. These growths still continue for long time after the combustion, by increasing the exposure risk.

Constructing a traditional Chinese medicine data warehouse application

The explosive growth in the development of Traditional Chinese Medicine (TCM) has resulted in the continued increase in clinical and research data. The lack of standardised terminology, flaws in data quality planning and management of TCM informatics are preventing clinical decision-making, drug discovery and education. This paper argues that the introduction of data warehousing technologies to enhance the effectiveness and durability in TCM is paramount. To showcase the role of data warehousing in the improvement of TCM, this paper presents a practical model for data warehousing with detailed explanation, which is based on the structured electronic records, for TCM clinical researches and medical knowledge discovery.

Birth and expansion of innovation ecosystems: A case study of copper production

Despite the growing attention innovation ecosystems have received from scholars and practitioners, rather little is known about the crucial birth and expansion phases that these ecosystems experience. Through a single case in the complex product system (CoPS) environment, this paper investigates the development of an innovation ecosystem between 1980 and 2007. The findings demonstrate that the ecosystem’s birth phase includes sub-phases, namely, invention and start-up, where the ecosystem is reconfigured to find the appropriate form and the proper actors to satisfy the first customer’s requirements. Moreover, the duration of the expansion phase is found to be remarkably long, suggesting that within the CoPS setting, expansion may also include two or more sub-phases.

The modern day bystander: Online and face-to-face bystander actions of adolescents in traditional bullying and cyberbullying

This study investigated whether bystanders of traditional bullying and cyberbullying used face-to-face methods, online methods or both methods when reporting, discouraging and providing support to the victims of traditional bullying and cyberbullying. A questionnaire was completed by 348 high school students (Years 7 – 12) from seven independent schools in Australia. Overall, students predominantly utilized face-to-face methods when reporting to others for both types of bullying. Older students were more likely to use online methods to discourage the traditional bully (i.e., asking the bully to stop). Males and older students were more likely to use online methods to support victims of traditional bullying. Females were more likely to use face-to-face methods to support victims of cyberbullying. Implications for practice and future research are discussed.

Has the Crab Pulsar Magnetic-Field Grown After its Birth

We investigate the evolution of rotation period and spindown age of a pulsar whose surface magnetic field undergoes a phase of growth. Application of these results to the Crab pulsar strongly indicates that its parameters cannot be accounted for by the field growth theories.

Spin it to win it: A comparison of constraints-led versus traditional coaching approaches

This thesis aimed to compare the effects of constraints-led and traditional coaching approaches on young cricket spin bowlers, with a specific research focus on increasing spin rates (i.e., Revolutions per Minute). Participants were 22 spin bowlers from either an Australia state youth squad or an academy in England. Results indicate that adopting a constraints-led approach can benefit younger, inexperienced bowlers, whilst a traditional approach may assist more skilled, older bowlers. The findings are discussed with regards to how they may inform the learning design of training programs by cricket coaches.

Adaptability of Damara, Dorper and Traditional Meat Sheep Breeds in Semi-Arid Queensland

Reproductive rate is a major contributing factor to the profitability of a sheep meat enterprise. Low reproduction rate is a feature of sheep husbandry in semi-arid Queensland. High ambient temperatures are implicated in poor fertility (Moule 1970) where variation in response can be due to breed and to animals within a breed (Hopkins and Stephenson 1978). Breeds recently imported from South Africa were selected in arid environments and may be better adapted to pastoral conditions of northern Australia than traditional breeds. Animal production for a consuming world : proceedings of 9th Congress of the Asian-Australasian Association of Animal Production Societies [AAAP] and 23rd Biennial Conference of the Australian Society of Animal Production [ASAP] and 17th Annual Symposium of the University of Sydney, Dairy Research Foundation, [DRF]. 2-7 July 2000, Sydney, Australia. This study will investigate (a) the thermoregulatory ability of Damara, Dorper, Poll Dorset, Rambouillet, South African Meat Merino and Queensland medium wool Merino rams prior to joinings in the autumn and spring of 1999, 2000 and 2001 and (b) the association between thermoregulatory parameters (rectal temperature and respiration rate) and ewe fertility. Results for the initial autumn joining are reported in this paper.

Gustaf III inför sina undersåtar : Konsten att härska och politikens kulturhistoria

The dissertation analyses the political culture of Sweden during the reign of King Gustav III (1771-1792). This period commonly referred to as the Gustavian era followed the so-called Age of Liberty ending half a century of strong parliamentary rule in Sweden. The question at the heart of this study engages with the practice of monarchical rule under Gustav III, its ideological origins and power-political objectives as well as its symbolic expression. The study thereby addresses the very nature of kingship. In concrete terms, why did Gustav III, his court, and his civil service vigorously pursue projects that contemporaneous political opponents and, in particular, subsequent historiography have variously pictured as irrelevant, superficial, or as products of pure vanity? The answer, the study argues, is to be found in patterns of political practice as developed and exercised by Gustav III and his administration, which formed a significant part of the political culture of Gustavian Sweden. The dissertation is divided into three parts. The first traces the use and development of royal graces chivalric orders, medals, titles, privileges, and other gifts issued by the king. The practice of royal reward is illustrated through two case studies: the 1772 coup d état that established Gustav III s rule, and the birth and baptism of the crown prince, Gustav Adolf, in 1778. The second part deals with the establishment of the Court of Appeal in Vasa in 1776. The formation of the Appeals Court was accompanied by a host of ceremonial, rhetorical, emblematic, and architectural features solidifying its importance as one of Gustav III s most symbolic administrative reform projects and hence portraying the king as an enlightened monarch par excellence. The third and final part of the thesis engages with war as a cultural phenomenon and focuses on the Russo-Swedish War of 1788-1790. In this study, the war against Russia is primarily seen as an arena for the king and other players to stage, create and re-create as well as articulate themselves through scenes and roles adhering to a particular cultural idiom. Its codes and symbolic forms, then, were communicated by means of theatre, literature, art, history, and classical mythology. The dissertation makes use of a host of sources: protocols, speeches, letters, diaries, newspapers, poetry, art, medals, architecture, inscriptions and registers. Traditional political source material and literary and art sources are studied as totalities, not as separate entities. Also it is argued that political and non-fictional sources cannot be understood properly without acknowledging the context of genre, literary conventions, and artistic modes. The study critically views the futile, but nonetheless almost habitual juxtaposition of the reality of images, ideas, and metaphors, and the reality of supposedly factual historical events. Significantly, the thesis presumes the symbolic dimension to be a constitutive element of reality, not its cooked up misrepresentation. This presumption is reflected in a discussion of the concept of role , which should not be anachronistically understood as roles in which the king cast himself at different times and in different situations. Neither Gustav III nor other European sovereigns of this period played the roles as rulers or majesties. Rather, they were monarchs both in their own eyes and in the eyes of their contemporaries as well as in all relations and contexts. Key words: Eighteenth-Century, Gustav III, Cultural History, Monarchs, Royal Graces, the Vasa Court of Appeal, the Russo-Swedish War 1788–1790.

Osteopenia and rickets in the extremely low birth weight infant: A survey of the incidence and a radiological classification

A review was carried out of the radiographs of twenty-five infants with birth weights under 1000 G, who survived for more than twenty-eight days; eighteen of these had enough suitable films for a survey of the progressive bone changes which occur in these infants, including estimation of humeral cortical cross-sectional area. The incidence of the changes has been assessed and a typical progression of radiographic appearances has been shown, with a suggested system of staging. All infants showed some loss of bone mineral, with frank changes of rickets occurring in forty-four percent. Aetiological factors are mainly concerned with the difficulty of supplying and ensuring absorption of sufficient bone mineral (calcium and phosphate) and vitamin D. Liver immaturity may be another factor. Disease states additional to prematurity accentuate the problem. Rib fractures occurring around 80–90 days post-nataEy commonly draw attention to the bone disorder and are probably the major clinical factor of importance; there is a high incidence of associated lung disease of uncertain pathology. Attention is drawn to possible confusion with other bone disorders in the post-natal period.

Bysanttilaisten ja Akhaian ruhtinaskunnan väliset sotatoimet vuosina 1259-83 : Tapaustutkimus myöhäis-bysanttilaisesta sodankäynnistä

In my master thesis I analyse Byzantine warfare in the late period of the empire. I use military operations between Byzantines and crusader Principality of Achaia (1259–83) as a case study. Byzantine strategy was based (in “oriental manner”) on using ambushes, diplomacy, surprise attacks, deception etc. Open field battles that were risky in comparison with their benefits were usually avoided, but the Byzantines were sometimes forced to seek open encounter because their limited ability to keep strong armies in field for long periods of time. Foreign mercenaries had important place in Byzantine armies and they could simply change sides if their paymasters ran out of resources. The use of mercenaries with short contracts made it possible that the composition of an army was flexible but on the other hand heterogeneous – in result Byzantine armies were sometimes ineffective and prone to confusion. In open field battles Byzantines used formation that was made out from several lines placed one after another. This formation was especially suitable for cavalry battles. Byzantines might have also used other kinds of formations. The Byzantines were not considered equal to Latins in close combat. West-Europeans saw mainly horse archers and Latin mercenaries on Byzantine service as threats to themselves in battle. The legitimacy of rulers surrounding the Aegean sea was weak and in many cases political intrigues and personal relationships can have resolved the battles. Especially in sieges the loyalty of population was decisive. In sieges the Byzantines used plenty of siege machines and archers. This made fast conquests possible, but it was expensive. The Byzantines protected their frontiers by building castles. Military operations against the Principality of Achaia were mostly small scale raids following an intensive beginning. Byzantine raids were mostly made by privateers and mountaineers. This does not fit to the traditional picture that warfare belonged to the imperial professional army. It’s unlikely that military operations in war against the Principality of Achaia caused great demographic or economic catastrophe and some regions in the warzone might even have flourished. On the other hand people started to concentrate into villages which (with growing risks for trade) probably caused disturbance in economic development and in result birth rates might have decreased. Both sides of war sought to exchange their prisoners of war. These were treated according to conventional manners that were accepted by both sides. It was possible to sell prisoners, especially women and children, to slavery, but the scale of this trade does not seem to be great in military operations treated in this theses.
