Diameter fluctuations of branches, shoots, or fruits are related to plant transpiration and water potential. In the past, several models have related dendrometric variables and evapotranspiration on a daily scale. However, trunk–branch shrinkage occurs only between dawn and midday, while evapotranspiration occurs most of the day from sunrise to sunset. Previous models have failed to incorporate this key fact. The objective of the present study was to assess the relationship of hourly daily shrinkage (HDS) between dawn and the next 4 h to the hourly reference evapotranspiration (EToh) of the same period in walnut trees and pomegranate plants under different irrigation regimes. Our data show that the relationship between EToh and HDS is much better than several previous models that included maximum daily shrinkage (MDS) and reference evapotranspiration (ETo). The novel slope analysis of the relationship between HDS versus time used here corresponds to the velocity at which the HDS occurs, which depends on the ETo intensity at that moment. This new method of analyzing this type of data calls for a revision of these models and sets a new baseline for future analysis.

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.

The Latvian writer Gunars Janovskis (1916–2000) lived a long life, becoming the most productive Latvian exile prose writer not only in Great Britain but the whole Latvian exile community. Everything he saw, experienced, observed, and noticed in some way, was echoed in his literary work. Janovskis’ voluminous work offers diverse interpretation and analysis opportunities for a researcher of literature. The present article focuses on two of Janovskis’ prose texts – his novels “Sōla” (1963) and “Pilsēta pie upes” (‘A Town by the River’, 1992), belonging to different stages of the writer’s activity, as well as his life. For the literary characters depicted by Janovskis, it is vital to remember, avoid losing the past while they attempt to live in the present, though this may be rather hard at times. It has been commented regarding the works of Janovskis that in his books, people only are really living when they are remembering. The present article aims to view the aforementioned novels by Janovskis within the model of the relationship between the past and the present, mainly concentrating on the relationship of the main characters with the time. The novel “Sōla” is the first novel by Janovskis ever published in a book. The main protagonist is Arturs Skuja, returning to some past impressions alongside the present from time to time. The landscape and elements of nature bring back his memories, inviting comparisons with the things once seen in Bolderāja or Daugavgrīva. There is a second and much heavier layer of the past in the protagonist’s dramatic and even tragic experiences during the war, which haunt him during sleepless nights or even return like a ghost. The main tense of the story within this novel is the present. But the novel “Pilsēta pie upes”, written much later, shows a shift of accent. The story starts in the present reality – at the old people’s home “Straumēni”. The urge of the author to tell the life story of Ansis Klētnieks is obvious, but in this story, one can unmistakably recognise the reflections of the author himself, through the location depicted (there are clear parallels between the course of life of Ansis from Krustpils and that of the author). The urge to tell, testify, not remain silent is much more pronounced in the story. The author has become less ambiguously involved in documenting a dramatic era, being its eyewitness. The novels chosen for the present article mark the changes in the relationship of the Janovskis’ literary characters with the present and the past. While the narrative in the present basically dominates in the novel “Sōla”, the other novel, “Pilsēta pie upes”, shows the past events and narrative dominating over the present. In both works, the plot takes place in both Great Britain and Latvia, though with changing intensity. It can be concluded that for Gunars, Janovskis writing was a kind of therapy aimed at overcoming the past while still securing the memories from being lost.

The present article follows the relationship of the Romanian novelistic output between 1901 and 1932 with time and temporal distribution. Its emphasis falls on the degree of correlation between the time of publication and the time during which the events unfold for each corresponding novel, expressed through a variable coined “distance”. By making use of this variable, the temporal distribution of the novelistic corpus in the article clearly shows that the novelists’ focus gradually shifts towards contemporary events; while during the period between 1900 up until the outbreak of World War One, novelists were inclined to place the events of their works in the past, the War seems to have triggered an acute preoccupation with the immediate present. Lastly, the text touches upon two distinct subgenres of the novel, arisen out of their relationship to time, namely the historical novel and the so-called ‘contemporary novel’.

This booklet is a collection of the position statements accepted for the HRI’20 conference workshop “Social Cognition for HRI: Exploring the relationship between mindreading and social attunement in human-robot interaction” (Wykowska, Perez-Osorio & Kopp, 2020). Unfortunately, due to the rapid unfolding of the novel coronavirus at the beginning of the present year, the conference and consequently our workshop, were canceled. On the light of these events, we decided to put together the positions statements accepted for the workshop. The contributions collected in these pages highlight the role of attribution of mental states to artificial agents in human-robot interaction, and precisely the quality and presence of social attunement mechanisms that are known to make human interaction smooth, efficient, and robust. These papers also accentuate the importance of the multidisciplinary approach to advance the understanding of the factors and the consequences of social interactions with artificial agents.

Background: Oleanolic Acid (OA) is a ubiquitous product of triterpenoid compounds. Due to its inexpensive availability, unique bioactivities, pharmacological effects and non-toxic properties, OA has attracted tremendous interest in the field of drug design and synthesis. Furthermore, many OA derivatives have been developed for ameliorating the poor water solubility and bioavailability. Objective: Over the past few decades, various modifications of the OA framework structure have led to the observation of enhancement in bioactivity. Herein, we focused on the synthesis and medicinal performance of OA derivatives modified on A-ring. Moreover, we clarified the relationship between structures and activities of OA derivatives with different functional groups in A-ring. The future application of OA in the field of drug design and development also was discussed and inferred. Conclusion: This review concluded the novel achievements that could add paramount information to the further study of OA-based drugs.

This chapter approaches police records as a genre that gains from being considered in its relationships with other genres of writing. In particular, we will follow its long-standing relationship to detective fiction, the novel, and biography. Going further, the chapter emphasizes the intermedia character of police records not just in our time but also throughout their existence, indeed from their very origins. This approach opens to a more inclusive media history of police files. We will start with an analysis of the seminal late nineteenth-century French manuals prescribing the writing of a police file, the famous Bertillon-method manuals. We will then track their influence following their adoption nationally and internationally, with particular attention to the politics of their adoption in the colonies. We will also touch briefly on the relationship of early policing to other disciplines, such as anthropology and statistics, before moving to a closer look at its intersections with photography and literature.

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.
