Study design Anterior and posterior vertebral body heights were measured from sequential MRI scans of adolescent idiopathic scoliosis (AIS) patients and healthy controls. Objective To measure changes in vertebral body height over time during scoliosis progression to assess how vertebral body height discrepancies change during growth. Summary of background data Relative anterior overgrowth has been proposed as a potential driver for AIS initiation and progression. This theory proposes that the anterior column grows faster, and the posterior column slower, in AIS patients when compared to healthy controls. There is disagreement in the literature as to whether the anterior vertebral body heights are proportionally greater than posterior vertebral body heights in AIS patients when compared to healthy controls. To some extent, these discrepancies may be attributed to methodological differences. Methods MRI scans of the major curve of 21 AIS patients (mean age 12.5 ± 1.4 years, mean Cobb 32.2 ± 12.8º) and between T4 and T12 of 21 healthy adolescents (mean age 12.1 ± 0.5 years) were captured for this study. Of the 21 AIS patients, 14 had a second scan on average 10.8 ± 4.7 months after the first. Anterior and posterior vertebral body heights were measured from the true sagittal plane of each vertebra such that anterior overgrowth could be quantified. Results The difference between anterior and posterior vertebral body height in healthy, non-scoliotic children was significantly greater than in AIS patients with mild to moderate scoliosis. However there was no significant relationship between the overall anterior-posterior vertebral body height difference in AIS and either severity of the curve or its progression over time. Conclusions Whilst AIS patients have a proportionally longer anterior column than non-scoliotic controls, the degree of anterior overgrowth was not related to the rate of progression or the severity of the scoliotic curve.

From the Finnish Art Society to the Ateneum: Fredrik Cygnaeus, Carl Gustaf Estlander and the Roles of the Art Collection My dissertation deals with the Finnish Art Society and the development of its collection in the evolving field of the visual arts from the foundation of the society in 1846 to its exhibition in the Ateneum, a palace of art that was opened to the public in Helsinki in 1888. The main questions that it addresses are why and how the collection came into being, what its purpose was and what kind of future prospects were projected for it in the rapidly evolving field of the visual arts. I have examined the subject of my study from the perspectives of institutional history, the organisation of the field of art and the history of art collections. The prisms through which I have viewed the subject are the history of museums in Europe, the written history of art, the art association movement and the organisation of art education in relation to an ideology of enlightenment. Thus the activities of the Finnish Art Society are here mirrored for the first time in a wider context and the history of its collection located on the map of European collections. My research shows that the history of the collection of the Finnish Art Society initially depended on certain players in the visual arts and their particular leanings. The most important of these custodians were two long-serving chairmen of the society, Fredrik Cygnaeus (1807 1881) and Carl Gustaf Estlander (1834 1910). When the foundations for art activities had been laid through the establishment of the society, Cygnaeus and Estlander began to plan how the field of art might be moulded so as to improve the level of training for artists and to improve the quality of the collections and the opportunities for their display. Cygnaeus campaigned for the establishment of the Finnish Fine Arts Academy, while Estlander saw opportunities to combine the visual and applied arts. The findings of my research bring new information about the history of the collection of the Finnish Art Society, its profile, the professional abilities of those who were mainly responsible for developing it and the relationship between it and plans for reforming art education. The major findings are connected with the position of the collection in the field of art at different stages of its development. Despite the central monopoly of the Finnish Art Society in the field of art, the position of the collection was closely bound up with leading players in the field of art and their personal interests. This subservience also created an impediment to its full-blown enhancement and purposeful profiling, and it remained evident for a long time when the collection was seeking its own place in the Finnish art world.

The study analyses the prevention or endorsing of the crime of infanticide in Finland 1702 1807, rather than the result. Also the impacts of the female body, biology of childbirth and experiences of pregnancy are examined, together with insights from modern medical research. Circumstances are reconstructed by a critical reading of judicial records on all levels of the judicial system. In all 269 cases of infanticide and 142 accessory crimes within the jurisdiction of the Turku court of appeal are studied, with particular focus on exceptionally well recorded cases of 83 accused women and 41 women and men accused of being party to the crime. Secondary sources are medical and jurisprudential writings, the public debate on infanticide, broadsheets and letters asking the King for pardon. Infanticide was considered murder by law. Unmarried women were predetermined as the main culprits. Nevertheless, deliberate infanticides were rare and committed mostly in accomplice. The majority of the infanticides studied were cases where inexperienced and unmarried women accidentally had given birth alone and usually to a dead child. Unaware that the pain they were experiencing was in fact a labour, the accused women instinctively sought solitude to push out the child. Some misunderstood the birth as an urgent need to defecate. The unexpected delivery ended in hiding the baby without remorse. This crime was promoted by several factors in Finnish rural culture, amongst others that also married women hid their pregnancy. The immediate household members did not necessarily know about the childbirth and failed to help the woman. This typical pattern in most cases of infanticide in 18th century Finland is also recorded in modern cases of unknown pregnancies. Fear of accountability prevented witnesses testifying to the actual course of events. The truth remained elusive. With only a few exceptions, the women were sentenced to death or imprisonment. The majority of those accused of accomplice were acquitted. However, too harsh sentences for accidents affected the reporting of the crime. Criminal politics failed to curtail infanticide as the crime was unsatisfactorily addressed by law, society and the judicial system.

This chapter provides an overview of a recent shift in regulatory strategies to address copyright infringement toward enlisting the assistance of general purpose Internet Service Providers. In Australia, the High Court held in 2012 that iiNet, a general purpose ISP, had no legal duty to police what its subscribers did with their internet connections. We provide an overview of three recent developments in Australian copyright law since that decision that demonstrate an emerging shift in the way that obligations are imposed on ISPs to govern the actions of their users without relying on secondary liability. The first is a new privately negotiated industry code that introduces a 'graduated response' system that requires ISPs to pass on warnings to subscribers who receive allegations of infringement. The second involves a recent series of Federal Court cases where rightsholders made a partially successful application to require ISPs to hand over the identifying details of subscribers whose households are alleged to have infringed copyright. The third is a new legislative scheme that will require ISPs to block access to foreign websites that 'facilitate' infringement. We argue that these shifts represent a greater sophistication in approaches to enrolling general purpose intermediaries in the regulatory project. We also suggest that these shifts represent a potentially disturbing trend towards enforcement of copyright law in a way that does not provide strong safeguards for the legitimate constitutional due process interests of users. We conclude with a call for greater attention and research to better understand how intermediaries make decisions when governing the conduct of users, how those decisions may be influenced by both state and non-state actors, and how the rights of individuals to due process can be adequately protected.

1. The successful introduction of the red fox Vulpes vulpes into Australia in the 1870s has had dramatic and deleterious impacts on both native fauna and agricultural production. Historical accounts detail how the arrival of foxes in many areas coincided with the local demise of native fauna. Recent analyses suggest that native fauna can be successfully reintroduced to their former ranges only if foxes have been controlled, and several replicated removal experiments have confirmed that foxes are the major agents of extirpation of native fauna. Predation is the primary cause of losses, but competition and transmission of disease may be important for some species. 2. In agricultural landscapes, fox predation on lambs can cause losses of 1–30%; variation is due to flock size, health and management, as well as differences in the timing and duration of lambing and the density of foxes. 3. Fox control measures include trapping, shooting, den fumigation and exclusion fencing; baiting using the toxin 1080 is the most commonly employed method. Depending on the baiting strategy, habitat and area covered, baiting can reduce fox activity by 50–97%. We review patterns of baiting in a large sheep-grazing region in central New South Wales, and propose guidelines to increase landholder awareness of baiting strategies, to concentrate and coordinate bait use, and to maximize the cost-effectiveness of baiting programs. 4. The variable reduction in fox density within the baited area, together with the ability of the fox to recolonize rapidly, suggest that current baiting practices in eastern Australia are often ineffective, and that reforms are required. These might include increasing landholder awareness and involvement in group control programs, and the use of more efficient broadscale techniques, such as aerial baiting.

Pseudocercospora macadamiae causes husk spot of macadamia. Husk spot control would be improved by verifying the stages in fruit development susceptible to infection, and determine some of the climatic conditions likely to lead to high disease pressure periods in the field. Our results showed that the percent conidia germination and growth of germ tubes and mycelia of P. macadamiae were greatest at 26 degrees C, with better conidia germination associated with high relative humidity and free water. The exposure of match-head-sized and pea-sized fruit stages to natural P. macadamiae inoculum in the field led to 2 5-fold increases in husk spot incidence, and up to 8.5-fold increases in premature abscission, compared with unexposed fruit. Exposure of fruit stages later than match-head-sized and pea-sized fruit generally caused no further increases in disease incidence or premature abscission. Climatic conditions were found to have a strong influence on the behaviour of P. macadamiae, the host, oil accumulation, and the subsequent impact of husk spot on premature abscission. Our findings suggest that fungicide application should target fruit at the match-head-sized stage of development in order to best reduce yield losses, particularly in seasons where oil accumulation in fruit is prolonged and climatic conditions are optimal for P. macadamiae.

A mature Caribbean pine (Pinus caribaea var. hondurensis) silviculture experiment provided initial square spacing treatments of 1.8 m2, 2.4 m2, 3.0 m2 and 3.6 m2 (equal to 3088, 1737, 1111 and 772 stems/ha) that were thinned at age 10 years to 600, 400 and 200 stems/ha, retaining an unthinned control for each initial spacing. The trial was destructively sampled at age of 28 years and discs taken along 8 various stem heights were analysed for variation in basic density and SilviScan wood properties. In addition, the logs from ten stocking × thinning treatments were processed in a sawing study. Results indicate thinning effects were generally more pronounced than initial spacing effects. Fast growing trees produced wood with significantly higher average wood densities and higher average stiffness values. Detailed SilviScan densitometry results obtained radially and at various stem heights enabled construction of tree maps for wood properties, providing insights into the variation in juvenile to mature wood proportion across the initial and post-thinning stocking treatments studied. Dried dressed recovery was strongly related to tree size, and log value decreased consistently from butt to top logs across all treatments. The estimated value per hectare was highest in unthinned plots due to values being multiplied by high stem numbers per hectare. However, a complete economic analysis considering all cost structures is required to investigate the optimal silviculture to maximise economic returns to growers and processors. Improved understanding of the relationship between initial spacing, post-thinning stocking and wood and end-product quality should help to customize future forest management strategies required to produce better quality wood and wood products.

An important decision brand managers have to make when positioning their products in a retail setting is to whether price new line extensions at parity or let products vary in the price/quality spectrum. Despite the growing interest in vertical line extension issues, there has been little research investigating how product-line length affects extension favorability. Therefore, this paper investigates the framing effect that a product line price structure has on consumer judgments of vertical extensions and, in particular, of upscale extensions. A basic proposition of this research is that the parent brand price range affects the perceived or psychological distance between extension and parent brand, influencing extension favorability ratings. In two experiments, it is shown that positioning an upscale extension in the context of a wide product-line will lead to higher consistency perceptions between the parent brand and a new upscale extension than an equivalent upscale extension positioned in the context of a narrow parent brand product-line.

Purpose A fundamental aspect of hierarchical loyalty programs is that some consumers get rewards that others do not. Despite the widespread use of such programs, academics have long debated whether these benefits are outweighed by the potential negative impact of the differential treatment of customers. This study extends our understanding, examining the impact of message framing on consumers’ reactions to hierarchical loyalty structures. Design/methodology/approach Three online studies were conducted. Study 1 uses advertisements to manipulate the message frame’s emphasis (benefits vs. status). Study 2 manipulates consumers’ frame of thought by directing their attention to either changes in benefits or status. Finally, Study 3 uses the proposed framework to reconcile contradictory findings from past research. Findings Low-frequency customers who do not expect to qualify for a superior customer tier tend to reject hierarchical programs when thinking about status. In contrast, when these customers think about concrete rewards, loyalty program messages produce no negative reactions. High-frequency customers are positively affected by communication regardless of the type of benefits framed. Research limitations/implications All studies were done online potentially limiting the external validity of the results. Nevertheless, the impact of message framing on perceptions about the loyalty program seems to be quite robust across different studies and manipulations. Practical implications When communicating with low-frequency customers managers should avoid promising status; customers should instead be motivated based on concrete rewards. High-frequency customers are indifferent to alternative emphasis of communication frames. Originality/value Marketing academics have acknowledged the importance of being able to reward top customers without demotivating light and moderate users. Our research is the first to provide a solution to this issue.

In this paper both documentary and natural proxy data have been used to improve the accuracy of palaeoclimatic knowledge in Finland since the 18th century. Early meteorological observations from Turku (1748-1800) were analyzed first as a potential source of climate variability. The reliability of the calculated mean temperatures was evaluated by comparing them with those of contemporary temperature records from Stockholm, St. Petersburg and Uppsala. The resulting monthly, seasonal and yearly mean temperatures from 1748 to 1800 were compared with the present day mean values (1961-1990): the comparison suggests that the winters of the period 1749-1800 were 0.8 ºC colder than today, while the summers were 0.4 ºC warmer. Over the same period, springs were 0.9 ºC and autumns 0.1 ºC colder than today. Despite their uncertainties when compared with modern meteorological data, early temperature measurements offer direct and daily information about the weather for all months of the year, in contrast with other proxies. Secondly, early meteorological observations from Tornio (1737-1749) and Ylitornio (1792-1838) were used to study the temporal behaviour of the climate-tree growth relationship during the past three centuries in northern Finland. Analyses showed that the correlations between ring widths and mid-summer (July) temperatures did not vary significantly as a function of time. Early (June) and late summer (August) mean temperatures were secondary to mid-summer temperatures in controlling the radial growth. According the dataset used, there was no clear signature of temporally reduced sensitivity of Scots pine ring widths to mid-summer temperatures over the periods of early and modern meteorological observations. Thirdly, plant phenological data with tree-rings from south-west Finland since 1750 were examined as a palaeoclimate indicator. The information from the fragmentary, partly overlapping, partly nonsystematically biased plant phenological records of 14 different phenomena were combined into one continuous time series of phenological indices. The indices were found to be reliable indicators of the February to June temperature variations. In contrast, there was no correlation between the phenological indices and the precipitation data. Moreover, the correlations between the studied tree-rings and spring temperatures varied as a function of time and hence, their use in palaeoclimate reconstruction is questionable. The use of present tree-ring datasets for palaeoclimate purposes may become possible after the application of more sophisticated calibration methods. Climate variability since the 18th century is perhaps best seen in the fourth paper study of the multiproxy spring temperature reconstruction of south-west Finland. With the help of transfer functions, an attempt has been made to utilize both documentary and natural proxies. The reconstruction was verified with statistics showing a high degree of validity between the reconstructed and observed temperatures. According to the proxies and modern meteorological observations from Turku, springs have become warmer and have featured a warming trend since around the 1850s. Over the period of 1750 to around 1850, springs featured larger multidecadal low-frequency variability, as well as a smaller range of annual temperature variations. The coldest springtimes occurred around the 1840s and 1850s and the first decade of the 19th century. Particularly warm periods occurred in the 1760s, 1790s, 1820s, 1930s, 1970s and from 1987 onwards, although in this period cold springs occurred, such as the springs of 1994 and 1996. On the basis of the available material, long-term temperature changes have been related to changes in the atmospheric circulation, such as the North Atlantic Oscillation (February-June).
