The Relationship

Much has been written on the relationship of China and Africa in the past decade. However, the subject of Chinese migrant entrepreneurs in Africa and their articulation with African counterparts was little explored up to the early 2010s. Apparently, this research gap has been closed, as shown by four publications in recent years: three edited volumes and one monograph, focusing on this subject. In view of early prejudices on the passive or even disapproving reception of Chinese migrants by Africans, the state of the art underlines the importance and scope of African agency vis à vis Chinese migrant entrepreneurs in Africa. This has been underlined unison in the four books under review.

The Relationship

The subject of this thesis is the outcome of what might be termed a hereditary interest in the complex problem of the relationship of chronic infections to the psychoses and allied mental disorders. Circumstances enabled me, while still a student, to undertake very humbly the continuation of my father's researches in the Scottish Asylums' Laboratory at a point where his illness and death might have proved the closing of a long and arduous chapter. That this would have been so is, as far as I know, borne out by the fact that up to the present no work directly bearing on his later bacteriological studies has been published. The researches I have undertaken during the past six years have been an attempt to elucidate more clearly what exactly are the bacteriological factors at work, and, further, in what manner they attack the economy generally, and with what result. In my endeavour to verify and extend Ford-Robertson's views I have been singularly fortunate.

The signaling nucleotide (p)ppGpp has been the subject of intense research in the past two decades. Initially discovered as the effector molecule of the stringent response, a bacterial stress response that reprograms cell physiology during amino acid starvation, follow-up studies indicated that many effects of (p)ppGpp on cell physiology occur at levels that are lower than those needed to fully activate the stringent response, and that the repertoire of enzymes involved in (p)ppGpp metabolism is more diverse than initially thought. Of particular interest, (p)ppGpp regulation has been consistently linked to bacterial persistence and virulence, such that the scientific pursuit to discover molecules that interfere with (p)ppGpp signaling as a way to develop new antimicrobials has grown substantially in recent years. Here, we highlight contemporary studies that have further supported the intimate relationship of (p)ppGpp with bacterial virulence and studies that provided new insights into the different mechanisms by which (p)ppGpp modulates bacterial virulence.

There has been a considerable amount of attention called to the subject of phthisis in asylums lately, and since the publication of the report of the Tuberculosis Committee the subject has appeared in a broader light. Although much is being and has been done for the prevention of phthisis by means of the Sanatorium movement, and the varieties of the technique of hygiene which are included in that treatment, yet there are still many aspects of the disease (both in the sane and insane) which require precise investigation, such as the variations in the composition of the secretions and excretions when the body is in the state of phthisical toxæmia; the relationship of the tuberculous toxæmia to other toxæmias, such as the influenzal (27), gouty, etc.; the accumulation of toxins, and its relations to recurrent forms of disease. The number of deaths from tubercle here during the past year we find to be ten; in 1900 it was nine, and 1899 it was fifteen, so that from a percentage of 1.3 in 1899 it has dropped to 0'85 in 1901. On examining the position of this asylum in the tables drawn up by the Tuberculosis Committee (1) we find it tenth in the asylums in England and Wales which are classified under Division i, which asylums have a tubercular death-rate of from 0.5 to 2.2, the county asylum at Exminster having a percentage of 1.3. This compares favourably with other asylums, some in the Division 2 having a tubercular death-rate of 5.1 and 8 per cent. respectively.

Biologic Factors

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.

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.

Tocopherols and tocotrienols are natural compounds of plant origin, available in the nature. They are supplied in various amounts in a diet, mainly from vegetable oils, some oilseeds, and nuts. The main forms in the diet are α- and γ-tocopherol, due to the highest content in food products. Nevertheless, α-tocopherol is the main form of vitamin E with the highest tissue concentration. The α- forms of both tocopherols and tocotrienols are considered as the most metabolically active. Currently, research results indicate also a greater antioxidant potential of tocotrienols than tocopherols. Moreover, the biological role of vitamin E metabolites have received increasing interest. The aim of this review is to update the knowledge of tocopherol and tocotrienol bioactivity, with a particular focus on their bioavailability, distribution, and metabolism determinants in humans. Almost one hundred years after the start of research on α-tocopherol, its biological properties are still under investigation. For several decades, researchers’ interest in the biological importance of other forms of vitamin E has also been growing. Some of the functions, for instance the antioxidant functions of α- and γ-tocopherols, have been confirmed in humans, while others, such as the relationship with metabolic disorders, are still under investigation. Some studies, which analyzed the biological role and mechanisms of tocopherols and tocotrienols over the past few years described new and even unexpected cellular and molecular properties that will be the subject of future research.

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.

Everyday Communication

Research in English language teaching has highlighted the importance of teaching communication skills in the language classroom. Against the backdrop of extensive research in everyday communication, the goal of this research was to explore whether current discourse analytic research is reflected in the lessons and communication examples of five English language teaching textbooks, by using spoken requests as the subject of investigation. The textbooks were evaluated on five criteria deriving from research on politeness, speech act theory and conversation analysis. These included whether and the extent to which the textbooks discussed the cultural appropriateness of requests, discussed the relationship of requests and other contextual factors, explained pre-sequences and re-requests and provided adequate practice activities. This study found that none of the coursebooks covered all of the criteria and that some coursebooks actually had very inadequate lessons. The results of the textbook analysis demonstrate that teachers using these five coursebooks and designers of future coursebooks must improve their lessons on requests by using pragmatics research and authentic examples as a guide.

Eosinophilia is a constant feature of Loffler's endomyocardial fibrosis.1,2 Three cases of this syndrome have been described in which acute lymphoblastic leukemia was concurrently present.3,4 Cytogenetic evidence in one of these cases suggested that the eosinophilia was "reactive" because the eosinophils had a normal karyotype while the lymphoblasts showed chromosomal aneuploidy.4 The subject of eosinophilia and eosinophilic syndromes has been extensively reviewed by others.5-8 The purpose of this report is to describe a boy with long-standing eosinophilia who presented with intractable heart failure, striking peripheral blood eosinophilia, and 38% lymphoblasts in the bone marrow. Current thoughts concerning the relationship of endomyocardial fibrosis, acute lymphoblastic leukemia, and eosinophilia are summarized.

In the digital era, the success of the professional development of future specialists in the process of obtaining higher education largely depends on their professional orientation (PN). Despite the significant interest in the subject of the study, the problem of identifying the factors that affect PN remains poorly understood. The purpose of the study is to determine the factors of the formation of PN of students enrolled in training and retraining programs, and the features of PN in the digital era. The article reveals the content and structure of the PN of future specialists in the era of digitalization. According to the results of the empirical research, the relationship of students' PN with indicators of life-meaning orientations, motives for choosing a profession and training was revealed; the relationship between students' life-meaning orientations and indicators of motives for choosing a profession and training at the stage of digitalization of education. The factors influencing the personal condition, and the factors of the formation of the personal condition of students, who are trained according to the programs of training and retraining of specialists, have been determined. As a result of an empirical study, it was concluded that a negative impact on the formation of PN is created by factors caused by various life circumstances, lack of independence of decisions in choosing a profession, low reflection of life goals, prospects for the future, rigidity of volitional and personal qualities, internal conflict in the structure of personality relationships, low pleasure training and the like. At the same time, the level of PN is significantly higher among students who receive a second higher education and who understand its importance at the stage of digitalization of education.
