The research was undertaken in the hope of obtaining evidence in support of or against the view that the cerebellum exercises a direct influence on the spinal centres, as opposed to any indirect influence exerted through the agency of the cerebral cortex. The inferior peduncle of the cerebellum was accordingly divided on one side, the organ itself and its other peduncles being otherwise left intact, and the results obtained by this procedure were controlled by experiments in which the lateral tracts of the medulla oblongata were divided on one side without injury to the pyramid on the one hand or to the posterior columns and their nuclei on the other. Further control experiments consisted in dividing transversely the posterior columns and their nuclei a few millimetres above the calamus scriptorius, on one side, without including the lateral tracts of the medulla in the lesion.

All surgical methods used in the study of the brain in animals can be combined into two groups: 1) methods of direct and indirect shutdown of a particular part of the brain and 2) methods of non-mediocre brain stimulation by electric current or by mechanical, chemical or thermal effects. In the hands of different experimenters, depending on the goals and objects of research, these basic methods varied to one degree or another. All modifications were aimed at, on the one hand, to avoid brain injuries during trepanation as much as possible, and on the other hand, to gain access to the cerebral cortex without exposing it at the time of the observation itself. As can be judged from the literature collected from E. Abderhalden in Handbuch der biolog. Arbeitsmethoden to a certain extent this has already been achieved.


I am greatly indebted to Professor Victor Horsley for allowing me to carry out the investigations, the results of which are embodied in this paper, in the Pathological Laboratory of University College, London. My object in undertaking this research, was twofold, as I wished in the first place to obtain evidence in support of or against the view that the cerebellum exercises a direct influence on the spinal centres, as opposed to any indirect influence exerted through the agency of the cerebral cortex, and in the second place to ascertain whether any descending tract could be traced from the cerebellum, by way of which any such direct influence could be brought to bear on the spinal centres. It is, however, impossible for me to do more than deal with the first of these problems in the present paper.

Operational management or operations management, as established in many speciality papers, is an area of activity that is particularly important for the successful implementation of business activities and not only. From the point of view of the connections that can be established between this concept and the one regarding the staff management, we note the direct influence that the degree of motivation in the work, the commitment and the connection to the specific values of a certain organizational culture have on the performance of the subsidiary activities of the operations management. Effective operations management implies not only the optimal use of the organization’s resources, but also the engagement of staff through a behaviour whose specific features emphasize responsibility, teamwork, transparency, and commitment to assigned tasks. This article highlights the need for the staff to be connected as well as possible to the organization’s values and objectives; the efficient management of operations within it is closely connected to the level of harmonization between the values and objectives, on the one hand, and the interests and motivation of the employees, on the other hand.

This study looks into the influence of psychological capital of beauty service industry workers on their creative behavior and aims to empirically investigate causal relationships between variables by identifying the influence of empowerment and shared leadership, which are the mediator variables. For this purpose, convenient sampling was conducted on beauty service industry workers, and 711 was chosen as the final sample. The sampled data were analyzed using SPSS 24.0 and AMOS 23.0 programs. As a result, psychological capital was confirmed to have influence over empowerment with no direct influence on shared leadership and creative behavior but indirect influence mediated by empowerment on them. It was further confirmed that psychological capital has indirect influence mediated by empowerment and shared leadership. On the other hand, empowerment was found to have an influence on shared leadership and creative behavior, with also shared leadership having a significant influence on creative behavior.

This article attempts to present the focus, methodology, and preliminary results of an international collaborative research project on industrial democracy involving twelve countries in Europe including Yugoslavia and Israel. Rather than explaining variations in participation, power, and influence in terms of contingencies such as personal attributes and characteristics of participants, on the one hand, or structural and tech nological features of organization, on the other hand, the research looks at both de jure and de facto participation in terms of participative structure (PS), power distribution (PO), and their outcomes (O). Initial findings with respect to differences and similarities across countries are presented. One of the main conclusions to be derived from the research is that, whereas all countries reveal a consistent hierarchy in the organizations studied, political and economic environments institutionally reflected in de jure participation can, however, significantly modify hierarchical patterns in organizations, but apparently not dissolve them as such. Another finding reported is that workers' satisfaction is unaffected by their own direct influence or that of their works council. But workers value representa tive participation for its own sake, the more their influence or involvement. Further democratization may require a change in national legal arrangements.

It has become commonplace in the anti-generative literature to portray Chomsky as denying that any systematic relationship exists between linguistic form on the one hand and meaning and function on the other and, in particular, that the latter might exert any direct influence on the former. The purpose of this note is to challenge such portrayals by making reference to some of Chomsky's relevant published statements over the past three and one half decades.

In a small article under the title "de l'influence de l'corce grise sur la dilatation de la pupille", published in C. R. de la Socit de Biologie 1887 r. No. 13 I reported the results of my experiments on this question. The appearance of my work was caused by disagreement in the results obtained by Voshefontaine, Grnhagen and Bessau, on the one hand, and Kachanovsky, on the other, and was aimed not so much at studying the localization, already known then, of the cortical centers of pupil dilation, but rather to clarify the very method of action of the cortex.

Статья представляет собой первую часть исследования о возможных перекличках и влияниях между мыслителем VI в. Леонтием Византийским, в трудах которого формируется утончённый логико-философский и богословский аппарат для разрешения догматических споров, и, соответственно, паламитской и протоантипаламитской (латинофильской) мыслью Византии XIII-XIV вв. Хотя о прямом влиянии Леонтия на представителей обоих лагерей (соответственно, Феофана Никейского и Иоанна XI Векка) говорить не приходится, ряд звеньев логической преемственности в плане истории идей всё же удаётся установить. Это типология «вертикальных» и «горизонтальных» отношений человека с Богом у Леонтия и Феофана, с одной стороны (пример условноположительной рецепции Феофаном идей Леонтия); и, с другой стороны, почти полный отход от идей и наследия Леонтия (при использовании ограниченного числа его категорий) в хаотичной догматической системе Векка. На примере труда Векка «Об унии между Церквами старого и нового Рима» выделяются и анализируются тридцать четыре пункта, по которым патриарх-латинофил отходит как от православной догматики, так и от византийской философии. В качестве главной черты учения Векка называется тритеизм, бывший мишенью и для Леонтия. The article is the first part of our study concerning some possible repercussions and influences between the sixth-century thinker Leontius of Byzantium, in whose writings a complex logical, theological and philosophical apparatus for solving dogmatic controversies was being formed, on the one hand, and proto-Palamite and proto-anti-Palamite (Latinophile) thought of the thirteenthand fourteenth-century Byzantium, on the other. Although one cannot say about Leontius’ direct influence upon the representatives of the both hostile camps (resp., Theophanes of Nicaea and John XI Veccus), we can still discern some links in the logical chain of continuity between their ideas and Leontius’. These links include: a typology of «vertical» and «horizontal» Divine - human relations in Leontius and Theophanes (this is an example of Leontius’ ideas being possibly positively received and appropriated by Theophanes); but on the other side we see an almost complete setback from Leontius’ ideas and heritage in the chaotic dogmatic system by Veccus, although some limited number of Leontius’ categories might have been used by John. We make the case study of Veccus’ On the Union Between the Churches of the Old and the New Rome in which text we single out and analyze the 34 points of thought in which the Latinophile patriarch dissociated himself from both the Orthodox dogmatics and Byzantine philosophy in general. As the main trait of Veccus’ doctrine which had been criticized earlier by Leontius we call tritheism.

Book by prof. AE Shcherbaka represents an attempt to approach the main problems of psychiatry from the point of view of various variations and combinations of amoeboism of the nervous cells of the cerebral cortex. The theoretical background of clinical lectures gives them a very special position among other psychiatric textbooks; on the one hand, it turns out that integrity is convenient for the study of psychiatry, on the other, an insurmountable obstacle arises to the application of any other scale, except for the one accepted by the author, with a theoretical assessment of tukh or other provisions of his book.

Before I begin to describe the parts which form the subject of this communication, and to show how some of them are merely modified portions or developments of others that belong to the medulla oblongata , it will be advisable to recur to those morphological changes in the medulla, which I formerly pointed out as themselves arising from modifications of the spinal cord . And while in unravelling structures so extremely complex, such a course seems almost necessary to facilitate their comprehension, and convey to the reader a just notion of their morphological changes, in relation on the one hand, to the remaining parts of the encephalon, and on the other hand, to the spinal cord, it will afford me an opportunity of adding to this recapitulation some new facts that have been elicited by subsequent observation and a more extended experience. It is gratifying to know that many of the results of my previous researches have been found to throw considerable light on certain diseases of the nervous system, especially on some forms of paralysis; and my own pathological investigations, as well as a close study of nervous disorders, have not only enabled me to shape my present researches as much as possible in accordance with the requirements of the pathologist, but, by pointing to the probability of certain anatomical connexions suggested by morbid symptoms, they have sometimes been the means of directing the course of my dissections in a very peculiar way.
