Academic literature on the topic 'Concerning the subjects and manner of baptism'

Abstract Irenaeus of Lyons wrote Demonstration of the Apostolic Preaching (Epideixis) to encourage his readers of the solidity of their faith, especially as this faith was connected to baptism under the threefold seal: Father, Son, and Holy Spirit. The threefold nature of the baptismal formula drives Irenaeus’ discussion in Epid. 3-7 and is the point with which he concludes the work, saying, ‘error, concerning the three heads of our seal, has caused much straying from the truth’ (Epid. 100). Irenaeus structures the intervening chapters to show how Christian baptism is both a testimony to and participation with the Triune God referenced in the baptismal formula. The lack of explicit structural markers within the body of the text has resulted in a neglect of the trinitarian character of its structure. This article explores the manner in which Irenaeus of Lyons’ Demonstration provides insight into his understanding of the nature and activity of the Triune God based on his conviction that Christian baptism is both a testimony to and a participation with that Triune God.

Despite its rarity, hermaphroditism is often discussed in medieval texts in theoretical and practical contexts by canonists, theologians, and natural philosophers. For the canonist or theologian, hermaphroditism raised questions concerning baptism, marriage, entry to clerical orders, and legal status. For the natural philosopher, the hermaphrodite seemed to violate the strict dichotomy of male and female. Here I examine Albert the Great's natural-philosophical treatment of hermaphroditism. Albert rejects the view that hermaphrodites constitute a “third sex” and instead invokes Aristotle's authority to show that hermaphrodites are a “monstrous” flaw in nature. He carefully investigates the manner in which nature produces hermaphrodites in the womb and introduces a discussion of the generative capacity of hermaphrodites themselves. He concludes that they are incapable of reproducing in and of themselves (i.e., they are incapable of auto-fecundation) although they seem able to generate in another individual through coition.

This paper addresses stability and bifurcation analysis for common systems of solids in the framework of plasticity, of friction and of fracture mechanics. Although physically different, usual time-independent laws adopted in these domains lead to a certain mathematical similarity concerning the quasi-static behaviour of materials and structures. These mechanical systems can be described practically in the same mathematical manner concerning their quasi-static evolution and in particular concerning the stability of their response. Our objective is to present within this framework a review of principal results of the recent literature on these subjects in relation with some energy-related considerations and with an unified description based upon energy and dissipation analysis.

The offenses concerning safety and health at work have no material object, their constitutive content including: the object and subject of the offense, the objective and subjective side of the offense. The active subjects of an offense have a legal obligation to apply and control the implementation of occupational safety and health measures and the passive subjects will bear the consequences of the occurrence of specific events. The existence of some uncertainties in the current legislation, also affecting mining companies, creates legal disputes especially in relation to the issues concerning active subjects. As for the passive subjects, the legal loophole refers to the situation of the day-labourers who may be involved in accidents at work and occupational illnesses. The authors consider it is necessary to formulate new law articles for clarification and even to draw up a future law with concrete reference to day-labourers, but also to some new risk sensitive social groups. Thus, the egal work relationships: the manner of performing the work, its remuneration and subordination to the beneficiary carrying out mining activities, will also be specified.

A clinical trial is one of the most important examples of experimental studies. Clinical trials represent an indispensable tool for testing, in a rigorous scientific manner, the efficacy of new therapies. Good Clinical Practice is an international ethical and scientific quality standard for clinical trials, concerning the design, conduct, performance, monitoring auditing, recording, analysis and reporting. This is an assurance to the public that the rights, safety and well-being of trial subjects are protected, and that clinical trial data is credible. The above definitions are consistent with the principles that have their origin in the declaration of Helsinki. The objectives of Good Clinical Practice are to protect the rights of trial subjects, to enhance credibility of data and to improve the quality of science.

By addressing a case of data collection strategies applied in research on Thai migration to the Swedish wild-berry industry, this article argues for how a feminist approach based on care and concern for research subjects both safeguards ethical concerns and promotes good knowing. The data collection procedures were designed in a step-by-step manner, including the research subjects as much as possible at different times and in different ways in an attempt to create preconditions for a more inclusive production of knowledge. In-depth interviews, participant observation, photo documentation and group interviews were used, which facilitated the possibility to understand the content and meanings of wild-berry picking from the workers’ points of view. Through prolonged contact, including repeated encounters and dialogue with research subjects, in-depth knowledge was produced concerning Thai migrations to Sweden, as migration was set in relation to the migrants’ life courses and living conditions.

In their theories of international order, Hobbes and Kant are not as far apart as earlier interpreters have claimed. Both consider peace between states and mutual respect for their sovereign independence to be necessary for securing domestic order. For both Hobbes and Kant, order arises from the very “independency” of states in a manner that is different from the independence of individuals in a state of nature. Both regard the independency of states and their commitment to the prosperity of their subjects as principles that support a long-term orientation toward peaceable cooperation. The most significance difference between Hobbes and Kant concerning international order arises from Kant’s attributing to individuals a cosmopolitan right that makes the international order more subject to potential conflict concerning the rights of individuals, but also gives his theory a stronger normative framework for the development of shared norms than what is found in Hobbes’s political theory.

In pregnancy, the decidual cells produce and secrete large amounts of macrophage colony-stimulating factor (M-CSF). M-CSF stimulates the proliferation and differentiation of trophoblasts. In addition, it stimulates them in a dose-dependent manner to produce certain hormones, such as human chorionic gonadotropin and human placental lactogen. Based on these facts, M-CSF is considered to be an essential cytokine for placental maintenance. Because placental dysfunction may sometimes result from preeclampsia, ascertaining blood M-CSF levels in preeclamptic patients would be of interest. The blood was collected from 33 subjects, of whom 19 were normal pregnant women and 14 were preeclamptic patients. The M-CSF level was determined by the sandwich enzyme-linked immunosorbent assay method using three antibodies. The investigators measured peripheral blood M-CSF levels in preeclamptic subjects and compared them with levels in subjects with normal pregnancies. This study showed that peripheral blood M-CSF levels were significantly higher in preeclamptic patients in the 30th and 38th weeks of pregnancy (P < .005). This is the first report concerning high M-CSF blood levels in preeclamptic patients.

The analysis of gait cycle represents for the professional in biomechanical field a source of information concerning the normality status, comfort degree in carrying out various activities, existence and manifestation of some loco-motor malfunctions, manner and degree of recovery/rehabilitation after surgery and many other applications. From this point of view, computerized simulation with respect to the anthropometric dimensions and the type of action represents an efficient and flexible manner for analysis and evaluation or even for creating a comparative algorithm between different situations or stages of motions performed by the locomotion system. Thus, some general aspects concerning the human locomotion system, the physiological and anatomical limits are presented in the first part of the paper. The analysis and simulation methodology for various gait types, also the experimental system used for recording and then processing the data obtained from these simulations are described in the second part of the paper. In order to complete the developed structure, these options of gait cycle were simulated by the computer, using dedicated software, either by blocking the hip joint or the knee joint, then they were correlated with the normal ones. The results and conclusions of these simulations and recordings on a target group of 10 subjects without locomotion malfunctions but simulating the blocked joints were presented in the final part of the paper.

The paper aims to throw light in what manner the theory of attachment can be applied in practice. The following applied studies act as intermediaries connecting theory and practice: (a) studies concerning the place and the role of attachment in partnership, parental and family functioning; (b) those concerning attachment and dysfunctional forms of behavior and (c) those concerning counseling and therapeutic applications of the attachment theory. In the paper these are illustrated by concrete research subjects and approaches. Main findings have been put in relation with the field of practical application. In the final part of the work, the author deals with the nature, the dynamics and the phases of relation between knowledge gained through theoretical research and its application in practical work. The author draws the conclusion that the relation between theory and practice, in the field of the attachment theory, is in the phase of early development characterized by asymmetric developmental levels and unidirectional influence. Highly developed theory enriches the practice by providing the basis for understanding the development and close relations; practice validates theory and its usability. However, the level of mutual influence where the practice of direct work with individuals would shape the theory has not been reached.

The originally Hobbesian ideal of twentieth-century neoclassical economics as a discipline that studies human interaction “more geometrico” as a scenery of interactive rational decision making is rejected. “Explaining” overt behavior as (if it were) the equilibrium outcome of opportunity seeking rational choices is impossible if the requirement of approximate truth of the explanans is upheld. Stylized accounts of some central experiments (prisoner’s dilemma, ultimatum, dictator, impunity games, double oral auctions) show why this is so and illustrate basic contributions of experimental economics in an exemplary manner. A somewhat detailed account of an experiment concerning “equity” shows the explanatory potential and “workings” of experimental economics and how its findings can contribute to traditional philosophical and psychological discussions. Why the Humean “attempt to introduce the experimental method of reasoning into moral subjects” must remain incomplete until experimental economics and experimental psychology become fully complementary research strategies is indicated as well.

Machine learning is becoming more and more important for mechatronic systems and will become an ordinary part of today's student life. Thus, it is obvious that machine learning should be part of today's student's curriculum. Unfortunately, machine learning seldomly is implemented into the curriculum in a substantial or linking manner, but rather offered as an elective course. This chapter provides an analysis of how machine learning can be integrated as a mandatory part of the curriculum of mechatronic degree courses. It is considered what the required minimal changes in fundamental courses should be and how traditional subjects like robotics, automation, and automotive engineering can profit most of this approach. As a case study, this chapter utilizes an existing German mechatronic degree course specialized on information technology, which covers most of the discussed aspects.

This chapter considers a number of additional subjects. It first considers the determination of sanctions under a communications-based prohibition, focusing on differences that arise when employing a communications-based prohibition rather than when basing liability on the presence of successful oligopolistic coordination. The chapter then turns to an alternative rule under which liability cannot be based on circumstantial evidence, contrary to the long-standing norm in competition law. Hereafter, implications of the contrasting approaches for other areas of competition law, such as the stringency of limits on horizontal mergers and the regulation of practices that might facilitate oligopolistic coordination, are discussed. Finally, the chapter looks into the manner in which rapid evolution in communications technology might influence the analysis, particularly concerning detection.

A cohort study is one in which the outcome (usually disease status) is ascertained for groups of individuals defined on the basis of their exposure. At the time exposure status is determined, all must be free of the disease. All eligible participants are then followed up over time. Since exposure status is determined before the occurrence of the outcome, a cohort study can clarify the temporal sequence between exposure and outcome, with minimal information bias. The historical and the population cohort study (Box 9.1) are efficient variants of the classical cohort study described above, which nevertheless retain the essential components of the cohort study design. The exposure can be dichotomous [i.e. exposed (to obstetric complications at birth) vs. not exposed], or graded as degrees of exposure (e.g. no recent life events, one to two life events, three or more life events). The use of grades of exposure strengthens the results of a cohort study by supporting or refuting the hypothesis that the incidence of the disease increases with increasing exposure to the risk factor; a so-called dose–response relationship. The essential features of a cohort study are: ♦ participants are defined by their exposure status rather than by outcome (as in case–control design); ♦ it is a longitudinal design: exposure status must be ascertained before outcome is known. The classical cohort study In a classical cohort study participants are selected for study on the basis of a single exposure of interest. This might be exposure to a relatively rare occupational exposure, such as ionizing radiation (through working in the nuclear power industry). Care must be taken in selecting the unexposed cohort; perhaps those working in similar industries, but without any exposure to radiation. The outcome in this case might be leukaemia. All those in the exposed and unexposed cohorts would need to be free of leukaemia (hence ‘at risk’) on recruitment into the study. The two cohorts would then be followed up for (say) 10 years and rates at which they develop leukaemia compared directly. Classical cohort studies are rare in psychiatric epidemiology. This may be in part because this type of study is especially suited to occupational exposures, which have previously been relatively little studied as causes of mental illness. However, this may change as the high prevalence of mental disorders in the workplace and their negative impact upon productivity are increasingly recognized. The UK Gulf War Study could be taken as one rather unusual example of the genre (Unwin et al. 1999). Health outcomes, including mental health status, were compared between those who were deployed in the Persian Gulf War in 1990–91, those who were later deployed in Bosnia, and an ‘era control group’ who were serving at the time of the Gulf war but were not deployed. There are two main variations on this classical cohort study design: they are popular as they can, depending on circumstances, be more efficient than the classical cohort design. The population cohort study In the classical cohort study, participants are selected on the basis of exposure, and the hypothesis relates to the effect of this single exposure on a health outcome. However, a large cohort or panel of subjects are sometimes recruited and followed up, often over many years, to study multiple exposures and outcomes. No separate comparison group is required as the comparison group is generally an unexposed sub-group of the panel. Examples include the British Doctor's Study in which over 30,000 British doctors were followed up for over 20 years to study the effects of smoking and other exposures on health (Doll et al. 1994), and the Framingham Heart Study, in which residents of a town in Massachusetts, USA have been followed up for 50 years to study risk factors for coronary heart disease (Wolf et al. 1988). The Whitehall and Whitehall II studies in the UK (Fuhrer et al. 1999; Stansfeld et al. 2002) were based again on an occupationally defined cohort, and have led to important findings concerning workplace conditions and both physical and psychiatric morbidity. Birth cohort studies, in which everyone born within a certain chronological interval are recruited, are another example of this type of study. In birth cohorts, participants are commonly followed up at intervals of 5–10 years. Many recent panel studies in the UK and elsewhere have been funded on condition that investigators archive the data for public access, in order that the dataset might be more fully exploited by the wider academic community. Population cohort studies can test multiple hypotheses, and are far more common than any other type of cohort study. The scope of the study can readily be extended to include mental health outcomes. Thus, both the British Doctor's Study (Doll et al. 2000) and the Framingham Heart Study (Seshadri et al. 2002) have gone on to report on aetiological factors for dementia and Alzheimer's Disease as the cohorts passed into the age groups most at risk for these disorders. A variant of the population cohort study is one in which those who are prevalent cases of the outcome of interest at baseline are also followed up effectively as a separate cohort in order (a) to study the natural history of the disorder by estimating its maintenance (or recovery) rate, and (b) studying risk factors for maintenance (non-recovery) over the follow-up period (Prince et al. 1998). Historical cohort studies In the classical cohort study outcome is ascertained prospectively. Thus, new cases are ascertained over a follow-up period, after the exposure status has been determined. However, it is possible to ascertain both outcome and exposure retrospectively. This variant is referred to as a historical cohort study (Fig. 9.1). A good example is the work of David Barker in testing his low birth weight hypothesis (Barker et al. 1990; Hales et al. 1991). Barker hypothesized that risk for midlife vascular and endocrine disorders would be determined to some extent by the ‘programming’ of the hypothalamo-pituitary axis through foetal growth in utero. Thus ‘small for dates’ babies would have higher blood pressure levels in adult life, and greater risk for type II diabetes (through insulin resistance). A prospective cohort study would have recruited participants at birth, when exposure (birth weight) would be recorded. They would then be followed up over four or five decades to examine the effect of birth weight on the development of hypertension and type II diabetes. Barker took the more elegant (and feasible) approach of identifying hospitals in the UK where several decades previously birth records were meticulously recorded. He then traced the babies as adults (where they still lived in the same area) and measured directly their status with respect to outcome. The ‘prospective’ element of such studies is that exposure was recorded well before outcome even though both were ascertained retrospectively with respect to the timing of the study. The historical cohort study has also proved useful in psychiatric epidemiology where it has been used in particular to test the neurodevelopmental hypothesis for schizophrenia (Jones et al. 1994; Isohanni et al. 2001). Jones et al. studied associations between adult-onset schizophrenia and childhood sociodemographic, neurodevelopmental, cognitive, and behavioural factors in the UK 1946 birth cohort; 5362 people born in the week 3–9 March 1946, and followed up intermittently since then. Subsequent onsets of schizophrenia were identified in three ways: (a) routine data: cohort members were linked to the register of the Mental Health Enquiry for England in which mental health service contacts between 1974 and 1986 were recorded; (b) cohort data: hospital and GP contacts (and the reasons for these contacts) were routinely reported at the intermittent resurveys of the cohort; (c) all cohort participants identified as possible cases of schizophrenia were given a detailed clinical interview (Present State examination) at age 36. Milestones of motor development were reached later in cases than in non-cases, particularly walking. Cases also had more speech problems than had noncases. Low educational test scores at ages 8,11, and 15 years were a risk factor. A preference for solitary play at ages 4 and 6 years predicted schizophrenia. A health visitor's rating of the mother as having below average mothering skills and understanding of her child at age 4 years was a predictor of schizophrenia in that child. Jones concluded ‘differences between children destined to develop schizophrenia as adults and the general population were found across a range of developmental domains. As with some other adult illnesses, the origins of schizophrenia may be found in early life’. Jones' findings were largely confirmed in a very similar historical cohort study in Finland (Isohanni et al. 2001); a 31 year follow-up of the 1966 North Finland birth cohort (n = 12,058). Onsets of schizophrenia were ascertained from a national hospital discharge register. The ages at learning to stand, walk and become potty-trained were each related to subsequent incidence of schizophrenia and other psychoses. Earlier milestones reduced, and later milestones increased, the risk in a linear manner. These developmental effects were not seen for non-psychotic outcomes. The findings support hypotheses regarding psychosis as having a developmental dimension with precursors apparent in early life. There are many conveniences to this approach for the contemporary investigator. ♦ The exposure data has already been collected for you. ♦ The follow-up period has already elapsed. ♦ The design maintains the essential feature of the cohort study, namely that information bias with respect to the assessment of the exposure should not be a problem. ♦ As with the Barker hypothesis example, historical cohort studies are particularly useful for investigating associations across the life course, when there is a long latency between hypothesized exposure and outcome. Despite these important advantages, such retrospective studies are often limited by reliance on historical data that was collected routinely for other purposes; often these data will be inaccurate or incomplete. Also information about possible confounders, such as smoking or diet, may be inadequate.
