Abstract:
In the monograph the literature information about the nature of stochastic processes and their participation in the work of the brain and human behavior. Established that the real cognitive processes and mental functions associated with the procedural side of external events and the stochastic properties of the internal dynamics of brain systems in the form of fluctuations of their parameters, including cardiac rhythm generation and sensorimotor reactions. Experimentally proved that the dynamics of the measured physiological processes is in the range from chaotic regime to a weakly deterministic — fractal mode. Fractal mode determines the maximum order and organization homeostasis of cognitive processes and States, as well as high adaptive ability of the body systems with fractal properties. The fractal-chaotic dynamics is a useful quality to examine the actual physiological and psychological systems - a unique numerical identification of the order and randomness of the processes through calculation of fractal indices. The monograph represents the results of many years of experimental studies of the reflection properties of stochastic sensorimotor reactions, as well as stochastic properties of heart rate in children, Teens and adults in the age aspect in the speech activity and the perception of different kinds of music with its own frequency-spectral structure. Designed for undergraduates, graduate students and researchers that perform research and development on cognitive psychology and neuroscience.

Abstract:
Scientific evidence supports the proposition that prepubertal children fatigue less than adults when performing whole-body dynamic activities like maximal cycling, running bouts, and maximal voluntary isometric/isokinetic muscle contractions. Although the mechanisms underpinning differences in fatigue between children and adults are not all fully understood, there is a consensus that children experience less peripheral fatigue (i.e. muscular fatigue) than their older counterparts. Central factors may also account for the lower fatigability in children. Some studies report a higher reduction of muscle voluntary activation during fatiguing exercise in prepubertal children compared to adults. This could reflect a strategy of the central nervous system aimed at limiting the recruitment of motor units, in order to prevent any extensive peripheral fatigue. Further studies are required to clarify this proposition.

Abstract:
This chapter explores some Latin maxims embodying supposed rules of construction. Traditional accounts of the interpretation of deeds and contracts are notoriously replete with such maxims. In the twenty-first century, when the judiciary has made it clear that the courts are less hospitable to legal Latin, it is unsurprising that once-familiar maxims are fading from the scene. Nevertheless it is necessary to examine these traditional rules in order to determine whether any of them still have a contribution to make to the construction of instruments. Moreover, it is suggested that in the modern law such canons have the potential to be reformulated in one of two ways.

Abstract:
This chapter, found in the headache section of the book, provides a succinct synopsis of a key study examining the use of computed tomography (CT) to rule out a head bleed or subarachnoid hemorrhage among patients with acute headaches. This summary outlines the study methodology and design, major results, limitations and criticisms, related studies and additional information, and clinical implications. Researchers reported that the criteria had high sensitivity and high negative predictive value for identifying subarachnoid hemorrhage among patients presenting to the emergency department with acute nontraumatic headache that reached maximal intensity within 1 hour and with normal neurologic examinations. In addition to outlining the most salient features of the study, a clinical vignette and imaging example are included in order to provide relevant clinical context.

Full text
Abstract:
Antonio Caso rejects the effort of biologists to reduce life to the organic world, a sphere of existence that is defined by economy and egoism, best summarized in the formula: Life = Minimum Effort x Maximum Gain. The problem is that this cannot explain what he calls “disinterested activity,” such as play, art, and self-sacrifice. His primary example of disinterested or selfless activity is the life of Jesus, which Caso also believes is the height of human dignity. In other words, Caso not only argues that there is more than one order of life or existence; he also argues that selfless activity is ultimately what distinguishes human life, whose best expression is found in the essence of Christianity: to give oneself to others “without fear of exhaustion.” To be human is to be willing to sacrifice oneself, best expressed in the following formula: Sacrifice = Maximum Effort x Minimum Gain.

Full text
Abstract:
Coleridge is presented as a two-level theorist of the innate powers of mind in Chapter 11, which argues that Coleridge distinguishes (1) a transcendental, Kantian sense of the a priori principles of human discursive cognition (comparable to Plato’s mid-level diánoia), from (2) the noëtic, Platonic a priori principles of intellectual intuition (or nóēsis, a higher-level intuitive cognition of ontological, theological, and ethical truths). Drawing on Logic and Opus Maximum, the author demonstrates that Coleridge characterizes Kantian a priori principles as ‘subjectively real’, finite-mind-dependent rules of sense-experience and cognition, and Platonic a priori principles as ‘objectively real’ principles of knowing and being that are dependent upon ‘the transcendent and unindividual’ reason (i.e. God, ‘the absolute Self, Spirit, or Mind’). This ‘two-level’ theory is framed in terms of Coleridge’s Kantian ‘threefold division’ of the human cognitive capacities into sense, understanding, and reason, and their respective a priori operations and contents.

Full text
Abstract:
Aerobic training is defined as exercise training that involves whole body endurance activity that is sustained for a sufficient length of time and at a sufficient intensity in order to improve cardiorespiratory fitness.1 The effect of aerobic training on physiological function in children has been investigated for nearly four decades. Some of this research has focused on the health-related benefits of this type of training on children and adolescents and for good reason. With increasing rates of obesity, type 2 diabetes, metabolic syndrome, and many other physical inactivity-related disorders, there is ample reason to discern the health-related effects of aerobic training during the paediatric years.2,3 However, there also has been a concerted effort to study the effect of aerobic training on the physiological adaptations, particularly maximal oxygen uptake ( V · O 2 max), that are associated with endurance performance.4 This chapter will focus on the latter consideration and will examine the effect of aerobic training in apparently healthy children and adolescents.

This chapter explores Japanese Zen material culture and materialism in a contemporary American monastic context. It examines the adaptation of mainstream business operations by The Monastery Store at Zen Mountain Monastery, established by John Daido Loori near Woodstock, New York, in 1980. It provides a visual and critical analysis of The Monastery Store’s mail-order catalogue, website, and brick-and-mortar facility on the monastery grounds, and it contrasts “retail Zen” (i.e., the mass marketing of vaguely Zen-like articles by multinational distribution chains for maximum profit) and “Zen retail” (i.e., the selective sale of sustainably sourced Zen items by nonprofit Zen monasteries to support adherents’ practice). In so doing, this analysis contributes to our understanding of Buddhist economics, practice, ethics, and other Zen matters.

Full text
Abstract:
This chapter examines one of the most underestimated areas of proof in investor-state arbitration—the proof of law. The first evidentiary principle governing proof of law is the maxim of iura novit curia, or the tribunal or court knows the law. The principle is fraught with difficulty when applied to investor-state arbitration. The practice of investor-state arbitration on its face disproves the assumption that tribunals know the law in a non-trivial sense. This difficulty does not mean, however, that iura novit curia is wholly inapplicable to investor-state arbitration. Rather, as the chapter shows, the principle must be carefully circumscribed in order to avoid potential annullable error.

Bose, Shibani. Mega Mammals in Ancient India. Oxford University Press, 2020. http://dx.doi.org/10.1093/oso/9780190120412.001.0001.

Full text
Abstract:
The book ventures to look into eras bygone in order to chronicle the passage of three mega species—the rhinoceros (Rhinoceros unicornis), tiger (Panthera tigris), and elephant (Elephas maximus)—across millennia in early north India. It carefully sifts through an archive comprising faunal remains and visual depictions retrieved from the archaeological record as well as a gamut of Sanskrit, Pali, Prakrit, and classical Western accounts to document the presence of these mega animals in various cultural niches from hunter-gatherer societies to the first urban civilization of India and beyond. The narrative goes beyond treating these species as mere cultural icons to one that is also sensitive to their importance as markers of ecology. The focus is two-fold: to comprehend perceptions, attitudes, and sensibilities oscillating between veneration and persecution in order to reconstruct the cultural dimensions of human–megafaunal relations in the past, as also to use these species to understand the larger ecology of ancient India. At a time when the conservation of our megafaunal heritage is a major concern for biologists, ecologists as well as conservationists, this book underlines the need to historicize human interactions with these mega mammals keeping in mind that an animal’s past is critical in thinking about its future.

Abstract:
In the current debate on the reform of association sanctioning, the Munich Draft (‘Münchner Entwurf eines Verbandssanktionengesetzes’) represents a proposal for a law with a sense of proportion. Unlike the Federal Ministry of Justice’s draft bill, the Munich Draft pursues a strictly commensurable way of sanctioning associations. For example, small associations are excluded from its scope of application, association responsibility, e.g. for actions taken by an employee against a superior’s orders, is explicitly excluded, and sanctions are differentiated between according to maximum turnover-related limits. In order to create incentives for behaviour that conforms to legal standards, the Munich draft sets out the requirements for compliance to it, both precautionary and post-offence, which can lead to privileges during prosecution and sanctioning. In addition, it regulates internal investigations in a separate chapter and grants extended protection against seizure. The authors of this study have dealt with commercial criminal law for decades as academics or practitioners.

Full text
Abstract:
Debating Education puts two leading scholars in conversation with each other on the subject of education—specifically, what role, if any, markets should play in policy reform. Each advances nuanced arguments and responds to the other, presenting contrasting views on education as a public good. One author argues on behalf of a market-driven approach, making the case that educational opportunities do not need to be equal in order to be good. The ideal of education is not equally preparing students to win a race but maximally preparing each student to make a contribution. The other focuses on inequality, particularly the unequal distribution of rewards. The argument is that justice requires prioritizing the prospects of the bottom 30 percent of the population, whose life prospects are much worse than justice would demand, given the current wealth of society. The moral imperative of education should be to improve this group’s range of opportunities. This part of the book expresses serious skepticism that market mechanisms are capable of this task, due to imperfections in educational markets, a lack of appropriate regulations, political influence, and other systemic obstacles.

Full text
Abstract:
The metaphor of ‘imprinting’ used to describe the process of education in Leviathan has long captured the imagination of commentators inclined to view Hobbes as a harbinger of modern totalitarianism. And yet its significance for recent scholarly debates about a ‘more tolerant’ Hobbes has been ignored. This chapter examines Hobbes’s metaphor in the broader context of his life and works in order to understand its implications for the sovereign’s role in regulating religion, not only outwardly, but in foro interno as well. Doing so reveals imprinting, like all of Hobbes’s metaphors, to have been carefully chosen. As a play both on a Platonic pedagogical analogy and the Pauline maxim, ‘Faith cometh by hearing’, it reflects Hobbes’s sensitivity to the curious moment in which he wrote—a moment in which the rise of a new culture of mass media and older traditions of philosophical and religious reflection on education would collide.

Abstract:
In the new edition of the Oxford Textbook of Neurorehabilitation all chapters have been updated to reflect advances in knowledge in the field of neurorehabilitation. It will be supplemented by additional chapters that reflect novel developments in the field of neurorehabilitation. During recent years there has been a strong evolution in the field of vocational rehabilitation with the aim of helping people after an injury of the nervous system to overcome the barriers and return to employment. A new chapter on self-management strategies deals with building confidence in individuals to manage the medical and emotional aspects of their condition. Furthermore, today the scientific basis for music supported therapy is a much broader to introduce it in this edition. New guidelines and consensus statements became established concerning preclinical research, biomarkers, and outcome measures, in both animal models and human beings. There are new data on attempts (e.g. using stem cells or Nogo antibodies) to restore function after spinal cord injury and stroke. Not all of these therapies and clinical trials have had positive outcomes. One particular area of rapid expansion reflects the use of technology in neurorehabilitation and several chapters remain devoted to this topic in various forms. Still a better understanding of the interactions of technology led therapies and conventional approaches in patients with neurodisability is required. There is still work to be done in defining key components of all neurorehabilitation interventions in order to understand how they might best be delivered for maximum benefit.

Torrance, Alexis. Human Perfection in Byzantine Theology. Oxford University Press, 2020. http://dx.doi.org/10.1093/oso/9780198845294.001.0001.

Full text
Abstract:
Christian theology has from its inception posited a powerful vision of humanity’s ultimate and eternal fulfilment through the person and work of Jesus Christ. That said, how precisely to understand and approach the human perfection to which the Christian is summoned is a question that has vexed the minds of many and diverse theologians. Orthodox Christian theology is notable for its consistent interest in this question, and over the last century has offered to the West a wealth of theological insight on the matter, drawn from both the resources of its Byzantine theological heritage as well as its living interaction with Western theological and philosophical currents. In this regard, the important themes of personhood, deification, epektasis, apophaticism, and divine energies have been elaborated with much success by Orthodox theologians; but not without controversy. This work addresses the question of human perfection in Orthodox theology via a retrieval of the sources, examining in turn the thought of leading representatives of the Byzantine theological tradition: St Maximus the Confessor, St Theodore the Studite, St Symeon the New Theologian, and St Gregory Palamas. The overarching argument of this study is that in order to present an Orthodox Christian understanding of human perfection which remains true to its Byzantine inheritance, supreme emphasis must be placed on the doctrine of Christ, especially on the significance and import of Christ’s humanity. The intention of this work is thus to keep the creative approach to human destiny in Orthodox theology firmly moored to its theological past.

Abstract:
Bones are multifunctional passive organs of movement that supports soft tissue and directly attached muscles. They also protect internal organs and are a reserve of calcium, phosphorus and magnesium. Each bone is covered with periosteum, and the adjacent bone surfaces are covered by articular cartilage. Histologically, the bone is an organ composed of many different tissues. The main component is bone tissue (cortical and spongy) composed of a set of bone cells and intercellular substance (mineral and organic), it also contains fat, hematopoietic (bone marrow) and cartilaginous tissue. Bones are a tissue that even in adult life retains the ability to change shape and structure depending on changes in their mechanical and hormonal environment, as well as self-renewal and repair capabilities. This process is called bone turnover. The basic processes of bone turnover are: • bone modeling (incessantly changes in bone shape during individual growth) following resorption and tissue formation at various locations (e.g. bone marrow formation) to increase mass and skeletal morphology. This process occurs in the bones of growing individuals and stops after reaching puberty • bone remodeling (processes involve in maintaining bone tissue by resorbing and replacing old bone tissue with new tissue in the same place, e.g. repairing micro fractures). It is a process involving the removal and internal remodeling of existing bone and is responsible for maintaining tissue mass and architecture of mature bones. Bone turnover is regulated by two types of transformation: • osteoclastogenesis, i.e. formation of cells responsible for bone resorption • osteoblastogenesis, i.e. formation of cells responsible for bone formation (bone matrix synthesis and mineralization) Bone maturity can be defined as the completion of basic structural development and mineralization leading to maximum mass and optimal mechanical strength. The highest rate of increase in pig bone mass is observed in the first twelve weeks after birth. This period of growth is considered crucial for optimizing the growth of the skeleton of pigs, because the degree of bone mineralization in later life stages (adulthood) depends largely on the amount of bone minerals accumulated in the early stages of their growth. The development of the technique allows to determine the condition of the skeletal system (or individual bones) in living animals by methods used in human medicine, or after their slaughter. For in vivo determination of bone properties, Abstract 10 double energy X-ray absorptiometry or computed tomography scanning techniques are used. Both methods allow the quantification of mineral content and bone mineral density. The most important property from a practical point of view is the bone’s bending strength, which is directly determined by the maximum bending force. The most important factors affecting bone strength are: • age (growth period), • gender and the associated hormonal balance, • genotype and modification of genes responsible for bone growth • chemical composition of the body (protein and fat content, and the proportion between these components), • physical activity and related bone load, • nutritional factors: – protein intake influencing synthesis of organic matrix of bone, – content of minerals in the feed (CA, P, Zn, Ca/P, Mg, Mn, Na, Cl, K, Cu ratio) influencing synthesis of the inorganic matrix of bone, – mineral/protein ratio in the diet (Ca/protein, P/protein, Zn/protein) – feed energy concentration, – energy source (content of saturated fatty acids - SFA, content of polyun saturated fatty acids - PUFA, in particular ALA, EPA, DPA, DHA), – feed additives, in particular: enzymes (e.g. phytase releasing of minerals bounded in phytin complexes), probiotics and prebiotics (e.g. inulin improving the function of the digestive tract by increasing absorption of nutrients), – vitamin content that regulate metabolism and biochemical changes occurring in bone tissue (e.g. vitamin D3, B6, C and K). This study was based on the results of research experiments from available literature, and studies on growing pigs carried out at the Kielanowski Institute of Animal Physiology and Nutrition, Polish Academy of Sciences. The tests were performed in total on 300 pigs of Duroc, Pietrain, Puławska breeds, line 990 and hybrids (Great White × Duroc, Great White × Landrace), PIC pigs, slaughtered at different body weight during the growth period from 15 to 130 kg. Bones for biomechanical tests were collected after slaughter from each pig. Their length, mass and volume were determined. Based on these measurements, the specific weight (density, g/cm3) was calculated. Then each bone was cut in the middle of the shaft and the outer and inner diameters were measured both horizontally and vertically. Based on these measurements, the following indicators were calculated: • cortical thickness, • cortical surface, • cortical index. Abstract 11 Bone strength was tested by a three-point bending test. The obtained data enabled the determination of: • bending force (the magnitude of the maximum force at which disintegration and disruption of bone structure occurs), • strength (the amount of maximum force needed to break/crack of bone), • stiffness (quotient of the force acting on the bone and the amount of displacement occurring under the influence of this force). Investigation of changes in physical and biomechanical features of bones during growth was performed on pigs of the synthetic 990 line growing from 15 to 130 kg body weight. The animals were slaughtered successively at a body weight of 15, 30, 40, 50, 70, 90, 110 and 130 kg. After slaughter, the following bones were separated from the right half-carcass: humerus, 3rd and 4th metatarsal bone, femur, tibia and fibula as well as 3rd and 4th metatarsal bone. The features of bones were determined using methods described in the methodology. Describing bone growth with the Gompertz equation, it was found that the earliest slowdown of bone growth curve was observed for metacarpal and metatarsal bones. This means that these bones matured the most quickly. The established data also indicate that the rib is the slowest maturing bone. The femur, humerus, tibia and fibula were between the values of these features for the metatarsal, metacarpal and rib bones. The rate of increase in bone mass and length differed significantly between the examined bones, but in all cases it was lower (coefficient b <1) than the growth rate of the whole body of the animal. The fastest growth rate was estimated for the rib mass (coefficient b = 0.93). Among the long bones, the humerus (coefficient b = 0.81) was characterized by the fastest rate of weight gain, however femur the smallest (coefficient b = 0.71). The lowest rate of bone mass increase was observed in the foot bones, with the metacarpal bones having a slightly higher value of coefficient b than the metatarsal bones (0.67 vs 0.62). The third bone had a lower growth rate than the fourth bone, regardless of whether they were metatarsal or metacarpal. The value of the bending force increased as the animals grew. Regardless of the growth point tested, the highest values were observed for the humerus, tibia and femur, smaller for the metatarsal and metacarpal bone, and the lowest for the fibula and rib. The rate of change in the value of this indicator increased at a similar rate as the body weight changes of the animals in the case of the fibula and the fourth metacarpal bone (b value = 0.98), and more slowly in the case of the metatarsal bone, the third metacarpal bone, and the tibia bone (values of the b ratio 0.81–0.85), and the slowest femur, humerus and rib (value of b = 0.60–0.66). Bone stiffness increased as animals grew. Regardless of the growth point tested, the highest values were observed for the humerus, tibia and femur, smaller for the metatarsal and metacarpal bone, and the lowest for the fibula and rib. Abstract 12 The rate of change in the value of this indicator changed at a faster rate than the increase in weight of pigs in the case of metacarpal and metatarsal bones (coefficient b = 1.01–1.22), slightly slower in the case of fibula (coefficient b = 0.92), definitely slower in the case of the tibia (b = 0.73), ribs (b = 0.66), femur (b = 0.59) and humerus (b = 0.50). Bone strength increased as animals grew. Regardless of the growth point tested, bone strength was as follows femur > tibia > humerus > 4 metacarpal> 3 metacarpal> 3 metatarsal > 4 metatarsal > rib> fibula. The rate of increase in strength of all examined bones was greater than the rate of weight gain of pigs (value of the coefficient b = 2.04–3.26). As the animals grew, the bone density increased. However, the growth rate of this indicator for the majority of bones was slower than the rate of weight gain (the value of the coefficient b ranged from 0.37 – humerus to 0.84 – fibula). The exception was the rib, whose density increased at a similar pace increasing the body weight of animals (value of the coefficient b = 0.97). The study on the influence of the breed and the feeding intensity on bone characteristics (physical and biomechanical) was performed on pigs of the breeds Duroc, Pietrain, and synthetic 990 during a growth period of 15 to 70 kg body weight. Animals were fed ad libitum or dosed system. After slaughter at a body weight of 70 kg, three bones were taken from the right half-carcass: femur, three metatarsal, and three metacarpal and subjected to the determinations described in the methodology. The weight of bones of animals fed aa libitum was significantly lower than in pigs fed restrictively All bones of Duroc breed were significantly heavier and longer than Pietrain and 990 pig bones. The average values of bending force for the examined bones took the following order: III metatarsal bone (63.5 kg) <III metacarpal bone (77.9 kg) <femur (271.5 kg). The feeding system and breed of pigs had no significant effect on the value of this indicator. The average values of the bones strength took the following order: III metatarsal bone (92.6 kg) <III metacarpal (107.2 kg) <femur (353.1 kg). Feeding intensity and breed of animals had no significant effect on the value of this feature of the bones tested. The average bone density took the following order: femur (1.23 g/cm3) <III metatarsal bone (1.26 g/cm3) <III metacarpal bone (1.34 g / cm3). The density of bones of animals fed aa libitum was higher (P<0.01) than in animals fed with a dosing system. The density of examined bones within the breeds took the following order: Pietrain race> line 990> Duroc race. The differences between the “extreme” breeds were: 7.2% (III metatarsal bone), 8.3% (III metacarpal bone), 8.4% (femur). Abstract 13 The average bone stiffness took the following order: III metatarsal bone (35.1 kg/mm) <III metacarpus (41.5 kg/mm) <femur (60.5 kg/mm). This indicator did not differ between the groups of pigs fed at different intensity, except for the metacarpal bone, which was more stiffer in pigs fed aa libitum (P<0.05). The femur of animals fed ad libitum showed a tendency (P<0.09) to be more stiffer and a force of 4.5 kg required for its displacement by 1 mm. Breed differences in stiffness were found for the femur (P <0.05) and III metacarpal bone (P <0.05). For femur, the highest value of this indicator was found in Pietrain pigs (64.5 kg/mm), lower in pigs of 990 line (61.6 kg/mm) and the lowest in Duroc pigs (55.3 kg/mm). In turn, the 3rd metacarpal bone of Duroc and Pietrain pigs had similar stiffness (39.0 and 40.0 kg/mm respectively) and was smaller than that of line 990 pigs (45.4 kg/mm). The thickness of the cortical bone layer took the following order: III metatarsal bone (2.25 mm) <III metacarpal bone (2.41 mm) <femur (5.12 mm). The feeding system did not affect this indicator. Breed differences (P <0.05) for this trait were found only for the femur bone: Duroc (5.42 mm)> line 990 (5.13 mm)> Pietrain (4.81 mm). The cross sectional area of the examined bones was arranged in the following order: III metatarsal bone (84 mm2) <III metacarpal bone (90 mm2) <femur (286 mm2). The feeding system had no effect on the value of this bone trait, with the exception of the femur, which in animals fed the dosing system was 4.7% higher (P<0.05) than in pigs fed ad libitum. Breed differences (P<0.01) in the coross sectional area were found only in femur and III metatarsal bone. The value of this indicator was the highest in Duroc pigs, lower in 990 animals and the lowest in Pietrain pigs. The cortical index of individual bones was in the following order: III metatarsal bone (31.86) <III metacarpal bone (33.86) <femur (44.75). However, its value did not significantly depend on the intensity of feeding or the breed of pigs.
