  GROUP-ANALYTIC PSYCHOTHERAPY WITH THE ELDERLY

  摘要：

  ABSTRACT Orthodox psychoanalysis offered the view that mental processes in the elderly are too rigidly established for favourable treatment results. Group psychotherapy with the elderly in general has received little attention, mostly concentrating on inpatient groups. The main focus has been on supportive techniques, often in institutional settings.Two of the authors (Maria Canete and Fiona Stormont) co‐conducted a weekly slow‐open analytic group for elderly people, in a London outpatient NHS clinic. This paper presents clinical material that illustrates some age‐specific issues, as they appear in the group process. For example, issues of competitiveness, rivalry and aggression, which are generally present in the beginning of groups with younger people, tend to be absent, or manifest themselves differently, in the elderly group. Denial of age becomes impossible, which helps these patients to accept approaching death and the process of dying itself. Psychoanalytic group psychotherapy can be especially indicated for this age population.

  Dynamics of endoergic substitution reactions. II. Br+{C₂H₂Cl₂}→Cl+{C₂H₂ClBr}

  摘要：

  We have extended the crossed beams studies described in the preceding paper to the reactions of Br atoms with 1,1- and trans-dichloroethylene. The shapes of the product translational energy distributions and excitation functions for both reactions support our previous conclusion that Cl elimination from Br–R–Cl collision complexes can compete with Br elimination only in the limit that few vibrational modes of the complex are active in energy redistribution. The substitution cross section for the Br+CH2CCl2 reaction is considerably lower than that for the Br+trans-CHClCHCl reaction in the collision energy range 15–25 kcal/mol, suggesting that steric effects play a dominant role in determining the relative magnitudes of the cross sections.

  BrCXCX2 respectively, where CXClCX2 represents the original chloro-ethylene. The rate of trichloromethyl radical addition to a chlorine-substituted site is slower than the rate of addition at CF2 and much slower than addition to CH2. Arrhenius parameters for the addition of CCl3· to the CH2 end of vinyl chloride have been measured:

  在气相实验中已经研究了光化学诱导将溴代三氯甲烷添加到一系列氯取代的乙烯中。加成不带氯原子的烯烃的碳原子会导致形成正常的加合物。当在带有氯原子的碳原子上发生三氯甲基自由基或溴原子的加成时，主要产物分别为CCl 2 CX CX 2和BrCX CX 2，其中CXCl CX 2代表原始的氯乙烯。三氯甲基自由基加到氯取代位的速率比在CF 2下的速率慢，比加到CH的速率慢得多2。已测量了向氯乙烯的CH 2末端添加CCl 3 ·的Arrhenius参数：
