Notizen: In this article the authors report the results of small group discussions with some 415 first-line supervisors in the mining industry. The results are compared with those from a number of earlier studies of mining. Changes which have affected the supervisory position are described, and the role of behavioural research in industry is discussed in relation to both organizational analysis and to training.

Notizen: This evaluation of Herzberg's theory of motivation discusses its ambiguities and the influence of the tendency for people to give “socially desirable” answers. Evidence from the authors' experiments suggests that the theory is untenable as a description of the structure of job attitudes and the determinants of job satisfaction and dissatisfaction. The authors acknowledge that a policy of job enrichment derived from the application of the theory would be likely to promote satisfaction and allay dissatisfaction. A concise summary of their analysis and conclusions is given at the end of the article.

Notizen: Research into some of the social/psychological factors in union management negotiations at plant level indicate that the party with the stronger case is more likely to ‘win’ when negotiating conditions are de-personalised and formal.

Notizen: Contemporary use patterns of land and water resources create conflicts between natural and human environments. These conflicts are generally not discussed as part of a classical approach to geologic education. This paper addresses the need to increase non-earth science training simultaneous with traditional training. The benefits to be gained will be welcomed by both students and their potential employers. One approach to suggested interdisciplinary water-resource education is discussed.

Notizen: This paper considers the nature of organizational conflict in general and conflict in the co-operative society in particular.It examines the unitary and pluralistic views of organizations and considers the suggestions that conflict is necessary for the independence of the individual, is constructive for the organization and is inevitable in any form of society. It investigates the proposed mechanisms for restraining conflict so that it is constructive.It is then argued that the co-operative retail society is a pluralistic organization comprising a number of different interest groups with their own sets of values. These groups tend to be engaged in an evaluation of the other groups and this evaluation carries with it the framework for competition rather than co-operation.It is contended that when economic conditions are favourable and there is a substantial surplus in the society the different groups can be satisfied and the inherent conflict remains submerged. The evaluation process is, in these conditions, latent, and internal competition is likely to be minimal. When economic conditions are unfavourable it is suggested that the divergent interests come to the surface. There is less dividend available for the members, the demands of managers and staff for higher wages and salaries may be difficult to meet, the members may be concerned about their capital and wish to draw it at a time when management want to retain it in the society. Within management the competition for scarce resources becomes sharper, and between management and staff there is increased tension as the former increase the pressure for greater efficiency. Economic values predominate and the holders of social values feel their position within the society to be threatened. To reassert themselves, they may stress the need for more effective democratic control. This emphasis on democratic control is a part of a wider feeling of anti-professionalism. This may take a number of forms, all, of which are aimed to redress the balance between managers and laymen. The attempt to establish firmer democratic control and the broader issue of anti-professionalism are both likely to intensify the conflict situation in a retail society at a time of economic stress.

Notizen: Summary. White ash (Fraxinus americana L.) trees, 2 years of age, treated continuously with 10 ppm picloram (4-amino-3,5,6-trichloropicolinic acid) in nutrient culture were only slightly injured after 4 weeks whereas red maple (Acer rubrum L.) trees were killed after only 2 weeks treatment.When the roots were exposed to 10 ppm 14C-picloram, the rate of root uptake, acropetal translocation in the stem, and accumulation in the leaves was much lower in the susceptible red maple than in the tolerant white ash. The foliar penetration and translocation of 14C-picloram applied to the leaves was very slight but similar in both species. Although a radiolabelled picloram metabolite was isolated from plant extracts, it was formed at equal rates in both species.It was concluded that the tolerance of white ash was not related to lower rates of picloram uptake or faster rates of picloram detoxication. It was postulated that the high susceptibility of red maple was due to a blockage of the xylem by picloram which caused death by a dessication of the leaves and upper stems. Action sélective du piclorame sur Fraxinus amerieana L. et Acer rubrum L.

Notizen: The anatomy of the shoot system of red maple and white ash was examined at various times after treatment with picloram. Xylem blockage, enlargement of cortical and pith cells and eventual necrosis of the shoot apex, parenchymatous and phloem tissues of red maple plants were features shown by picloram treatment. Red maple shoots were desiccated and dead by 22 days after treatment commenced. White ash shoots showed some increased mitotic activity but at the end of 22 days of picloram treatment, the leaves were still turgid and the internal anatomy of the shoot system scarcely altered. It is suggested that the susceptibility of red maple plants can be explained in part by the effects picloram has on xylem blockage and necrosis of parenchymatous tissues in the shoot system of this species.Effects du piclorame sur l'analomie de la partie aérienne de l'erable rouge et du frêne blancL'anatomie de la partie aérienne de l'érable rouge et du frêne blanc a été examinee i diverses dpoques aprés un traitement au piclorame. Le blocage du xyléme, le grossissement des cellules corticales et médullaires, ainsi qu'une Éventuelle nécrose des apex des tiges, des tissus parenchymateux et du phloéme des Arables rouges furent les effects consécutifs au traitement par le piclorame. La partie aérienne des Arables rouges se déssécha et mourut 22 jours aprés le déA but du traitement. La partie aérienne du Fréne blanc manifesta un accrolssement d'activité mitotique. mais, 22 jours aprés le traitement au piclorame, les feuilles étaient encore turgesccntes et l'anatomie interne des organes aériens k peine altérte. II est suggéré que la sensibility de rérable rouge peut être expliquée en partie par les effets du piclorame sur le blocage du xyléme et les necroses des tissus parenchymateux dans les organes adriens de cette espèce.Die Wirkung von Picloram auf die Anatomic des Sprosses von Acer rubrum L. und Fraxinus americana L.Es wurde die Anatomie des Sprosssystems von Acer rubrum L. und von Fraxinus americana L. zu verschiedencn Zeiten nach einer PJilorambehandlung untersucht. Bei Acer rubrum traten als Sympiome auf: Verstopfen des Xylems, VergröBerung der Rinden-und Markzellen und schliesslich Absterben der Sprossspitze, des parenchymatischen und des Phloemgewebcs. 22 Tage nach der Behandlung waren dis Sprosse ausgelrocknet und tot. Bei Fraxinus americana zeigten die Sprosse erhohte mitotische AktivitSt, aber 22 Tage nach der Piclorambehandlung waren die Blotter noch turgeszent und der innere Auf bau des Sprols systems war kaum verSndert. Die Befunde deuten darauf hin, daβ die Empfindlichkeit von Acer rubrum gegenuber Pictoram zum Teil mit seiner Wirkung auf das Xylem und das parenchymatische Gewebe im Sproβsystem erklärt werden kann.
