The Relationship

Cultivated caladiums are valued for their bright colorful leaves and are widely used in containers and landscapes. More than 1500 named cultivars have been introduced during the past 150 years, yet currently only about 100 cultivars are in commercial propagation in Florida. Caladium tubers produced in Florida account for 95% of the world supplies. Loss of caladium germplasm or genetic diversity has been a concern to future improvement of this plant. In addition, the relationship among the available cultivars, particularly those of close resemblance, has been lacking. This study was conducted to assess the genetic variability and relationship in commercial cultivars and species accessions. Fifty-seven major cultivars and 15 caladium species accessions were analyzed using the target region amplification polymorphism marker technique. This marker system does not involve DNA restriction or adaptor linking, but shares the same high throughput and reliability with the amplified fragment length polymorphism system (AFLP). Eight primer combinations amplified 379 scorable DNA fragments among the caladium samples. A high level of polymorphism was detected among the species accessions as well as among cultivars. These markers allowed differentiation of all the cultivars tested, including those hardly distinguishable morphologically. Clustering analysis based on these DNA fingerprints separated the cultivars into five clusters and Caladium lindenii far from other caladium species. The availability of this information will be very valuable for identifying and maintaining the core germplasm resources and will aid in selecting breeding parents for further improvement.

The study is devoted to the study of the structure of the interconnections of the components of the "I" -image of students with the various mental states they experience in the context of studying at a university. Students determined the severity of the components of the "I" -image in three time continua - in the past (1st year), in the present (3rd year), in the future (4th year). They also determined the frequency of occurrence of mental states during the first two years of study using a special questionnaire. Then a correlation analysis was carried out, which made it possible to find relationships with a high level of reliability between the components of the "I" -image of students and some mental states experienced in two educational situations, which differ qualitatively depending on the time continuum. Based on the results obtained, conclusions were drawn about the presence of relationships, thanks to which it is possible to exert a certain influence on the experienced mental sta

In a spirited treatise on the ‘Origin of our Animal World’ Prof. L. Rütimeyer, in the year 1867, described the geological development and distribution of the mammalia, and the relationship of the different faunas of the past with each other and with that now existing. Although, since the appearance of that masterly sketch the palæontological material has been, at least, doubled through new discoveries in Europe and more especially in North and South America, this unexpected increase has in most instances only served as a confirmation of the views which Rutimeyer advanced on more limited experience. At present, Africa forms the only great gap in our knowledge of the fossil mammalia; all the remaining parts of the world can show materials more or less abundantly, from which the course followed by the mammalia in their geological development can be traced with approximate certainty.

Dysregulation of the autonomic nervous system (ANS) may play an important role in the development and maintenance of persistent post-concussive symptoms (PPCS). Post-injury breathing dysfunction, which is influenced by the ANS, has not been well-studied in youth. This study evaluated cardiorespiratory functioning at baseline in youth patients with PPCS and examined the relationship of cardiorespiratory variables with neurobehavioral outcomes. Participants were between the ages of 13–25 in two groups: (1) Patients with PPCS (concussion within the past 2–16 months; n = 13) and (2) non-injured controls (n = 12). Capnometry was used to obtain end-tidal CO2 (EtCO2), oxygen saturation (SaO2), respiration rate (RR), and pulse rate (PR) at seated rest. PPCS participants exhibited a reduced mean value of EtCO2 in exhaled breath (M = 36.3 mmHg, SD = 2.86 mmHg) and an altered inter-correlation between EtCO2 and RR compared to controls. Neurobehavioral outcomes including depression, severity of self-reported concussion symptoms, cognitive catastrophizing, and psychomotor processing speed were correlated with cardiorespiratory variables when the groups were combined. Overall, results from this study suggest that breathing dynamics may be altered in youth with PPCS and that cardiorespiratory outcomes could be related to a dimension of neurobehavioral outcomes associated with poorer recovery from concussion.

A descriptive study of factors in the lifestyle of fifty couples married an average of 55.5 years and an average age of seventy-nine years provided data for this report. The non-random sample was heterogeneous using traditional socio-economic indicators. Life-Satisfaction (LSI-Z), Locke-Wallace Marital Adjustment scores, and perception of health were all high. More than half the sample were now or had been sexually active within the past five years. Independence, commitment, companionship and qualities of caring were significant elements in these long-lasting marriages.

Since the 1960s, Australian scientists have speculated on the impact of human arrival on fire regimes in Australia, and on the relationship of landscape fire to extinction of the Pleistocene megafauna of Australia. These speculations have produced a series of contrasting hypotheses that can now be tested using evidence collected over the past two decades. In the present paper, I summarise those hypotheses and review that evidence. The main conclusions of this are that (1) the effects of people on fire regimes in the Pleistocene were modest at the continental scale, and difficult to distinguish from climatic controls on fire, (2) the arrival of people triggered extinction of Australia’s megafauna, but fire had little or no role in the extinction of those animals, which was probably due primarily to hunting and (3) megafaunal extinction is likely to have caused a cascade of changes that included increased fire, but only in some environments. We do not yet understand what environmental factors controlled the strength and nature of cascading effects of megafaunal extinction. This is an important topic for future research.

‘Archive’ is a totality of records, layers and memories that are collected. A city is the archive that consists of the conscious selection of these layers and traces of the past and the present, looking towards the future. Metaxourgio is an area in the wider historic urban area of Keramikos in Athens that includes traces of various eras, beginning in the Antiquity and continuing all the way into the 21st century. Its archaeological space ‘Demosion Sema’ is mostly concealed under the ground level, waiting to be revealed. In this proposal, Metaxourgio is redesigned in light of archiving. Significant traces of the Antiquity, other ruins and buildings are studied, selected and incorporated in the new interventions. The area becomes the ‘open archive’ that leads towards its lost identity. The proposal aims not only to intensify the relationship of architecture with archaeology, but also to imbue the area’s identity with meanings that refer to the past, present and future.

An extended approach to the comprehension of virtual reality is developed in the article. Virtual reality is understood not only as a logically possible or cybernetically constructed reality but also as continuous turbulence of potencies of the complex natural and social world we live in, the wandering of complex systems and organizations over a field of possibilities, such a realization of forms and structures in which many formations remain in latent, potential forms, and are in the permanent process of making and multiplying a spectrum of possibilities, lead to the growth of the evolutionary tree of paths of development. It is shown that such an understanding of virtual reality corresponds to concepts and notions developed in the modern science of complexity. The most significant concepts are considered, such as the nonlinearity of time, the relationship of space and time, the uncertainty of the past and the openness of the future, the choice and construction of the future at the moments of passing the bifurcation points. Some cultural and historical prototypes of these modern ideas of virtual reality are given. It is substantiated that the vision of virtual reality being developed today can play the role of a heuristic tool for understanding the functioning and stimulation of human creativity.

This article suggests that bringing Jewish literature and Jewish thought into conversation can deepen our understanding of each. As an illustration of this interdisciplinary methodology, I offer a reading of Cynthia Ozick's 1987 Messiah of Stockholm. I claim that Ozick has embedded an argument about the relationship of post-Holocaust Jewry to the past into the literary features of her novel. Her argument draws in particular upon Leo Baeck's account of Judaism as focused on the present and future in contrast to the worshipful approach to the past characteristic of other religions. At the same time, I offer a more nuanced take on the fear of idolatry so often noted in analyses of Ozick's work and situate that fear in relationship to the literary theories of her predecessor Bruno Schulz, who plays a key role in the novel, and her contemporary Harold Bloom.

Animation is a synthesis of ideas that often encounters unpredictable, illogical, and imagined domains. In those animated worlds, recorded sound is now part of a coalition of two sensory forms mediated through hearing and vision. Sound has therefore been embedded in the audio-visual toolbox since the successful synchronisation of sound and picture. Sonic elements now contribute significantly to how animators might shape their films and express ideas. These animated worlds also often represent deeply rooted expressions of the interior mind of the artists and animators themselves. This chapter explores the relationship of sound to image in the evolutionary and increasingly variable animated forms that are currently proliferating. It aims to focus on sound as being the primary channel that is best able to reflect those interior ideas within a range of animated media. The exploration seeks to do this through tracing proto-cinematic ideas in the art of the past and animation practice that researches the sonified and animated image using musical and figurative metaphors.

The Relationship

This chapter examines Chinese migration and investment into Europe and explores models of migration and investment by identifying the gap between the two. The chapter highlights the major characteristics of Chinese investment and migration into Europe by identifying and separating the investment from Chinese state-owned enterprises (SOEs) and that of private individuals. This triangulation provides scholars and policy makers with a unique scenario. The migration and investment literature has been conducted as two separate and parallel topics. A small number of studies investigate the relationship of the two as one inter-connected relationship. There is even less focus on Chinese migration and investment due to the fact that over the past decade it has been a fast-moving phenomenon because of the speed of Chinese economic development. In addition, China's different political and economic system and its unique state structure adds another layer of complexity for scholars.
