Psigologiese benadering van pastorale arbeid

In die spreektaal van ons Afrikaanse kerke is ons lief om die bedienaar van die Woord aan te dui as „die predikant”, „die leraar” of „die dominee”. Miskien plaas ons met hierdie semantiese gebruik van terme wat lering en proklamering impliseer, ’n ongelukkige klem op die preekamp. Daarteenoor, het ons semanties miskien iets te leer van die Pinkstersektes wat die benaming „pastoor” verkies, of die Amerikaanse ge­ bruik van die term „the pastor”. Ons is wel lief om te praat van „ons herder en leraar”. Veelal word die herderlike, of pastorale, deel van die taak van die bedienaar van die Woord egter in sy eie gedagtes, asook in die gedagtes van sy gemeentelede, deur die leraarskap op die agtergrond gedwing. Al te dikwels word hy deur gemeentelede beskou as iemand wat op Sondag op die kansel gesien moet word en wat niks met die res van hul lewens te doen het nie. Herstel van die pastoraat sal deel moet wees van die proses om die ontkerstening van die hedendaagse lewe teen te gaan

Persoonlikheidsontwikkeling

Skerp begripsvorming i.v.m. die term „persoonlikheid” is ’n moeilike taak omdat dié term, en aanverwante terme, in beide die spreektaal en die vakliteratuur in velerlei betekenisse gebruik word. G. W. Allport (1937) het al 23 jaar gelede 49 omskrywings van persoonlikheid uit verskillende bronne versamel — en ’n vyftigste bygevoeg! Vanselfsprekend word die definisie wat die betrokke ondersoeker gee, bepaal deur sy teoretiese voorkeur, wat weer voortvloei uit sy lewens- en wêreldbeskouing

Die kliniese kindersielkundige as diagnostikus1)

Die benaming „Kliniese Kindersielkunde” is nog onbekend en gevolglik betreklik onbemind. Dit is in 1951 die eerste keer gebruik. Die werk van die Kliniese Kindersielkunde is egter so oud as die werk van die algemene Kliniese Sielkunde, waarvan die geskiedenis gewoonlik teruggevoer word tot die begin van sielkundige toetsing vroeg in die tagtigerjare. Tot ’n aansienlike mate is hierdie vroeë werk op kinders uitgevoer, bv. dié van Galton en later die van Binet en Simon. Witmer het in 1896 die eerste sielkundige kliniek geopen en het ook die term „Kliniese Sielkunde” ingevoer; die meerderheid van sy pasiënte was egter ook kinders. Tot voor die Tweede Wêreldoorlog was klinies-sielkundige werk hoofsaaklik op kinders toegespits. Sedertdien het die kliniese sielkundige tot ’n belangrike mate toegetree tot die gebied van die diagnose en terapie van psigiese afwykings by volwassenes, tot so ’n mate dat in die gedagtes en geskrifte van baie werkers die terrein van die Kliniese Sielkunde byna tot werk met volwassenes beperk word

Acceptance of co-operative education practice by the academic staff at Technikon Southern Africa.

Technikons advocate the practice of co-operative education, which is an educational strategy that integrates learning through productive work with the theoretical curriculum. However, only 35% of theTechnikon SA programmes have a compulsory experiential learning component. Grounded theory research was undertaken to determine some of the basic assumptions of Technikon SA’s academic staff in this regard. Rather than starting out with a specific research problem, grounded theory explores an area of interest and allows what is relevant to emerge. Semi-structured interviews with four open-ended questions, were conducted with a stratified-random sample of 25 teaching staff at Technikon SA. It was found that, although there is some willing compliance and belief in co-operative education, it is not indicative of the organisational culture of Technikon SA

Exteneded Longitudinal Scaling and the Thermal Model

The property of extended longitudinal scaling of rapidity distributions was noticed recently over a broad range of beam energies. It is shown here that this property is consistent with predictions of the statistical thermal model up to the highest RHIC beam energies, however, we expect that at LHC energies the rapidity distribution of produced particles will violate extended longitudinal scaling.Comment: 3 pages, 4 figure

Clergy work-related satisfactions in parochial ministry: the influence of personality and churchmanship

The aim of this study was to test several hypotheses that clergy work-related satisfaction could be better explained by a multidimensional rather than a unidimensional model. A sample of 1071 male stipendiary parochial clergy in the Church of England completed the Clergy Role Inventory, together with the short-form Revised Eysenck Personality Questionnaire. Factor analysis of the Clergy Role Inventory identified five separate clergy roles: Religious Instruction, Administration, Statutory Duties (conducting marriages and funerals), Pastoral Care, and Role Extension (including extra-parochial activities). Respondents also provided an indication of their predispositions on the catholic-evangelical and liberal-conservative dimensions. The significant associations of the satisfactions derived from each of the roles with the demographic, personality, and churchmanship variables were numerous, varied, and, with few exceptions, small in magnitude. Separate hierarchical regressions for each of the five roles indicated that the proportion of total variance explained by churchmanship was, in general, at least as great as that explained by personality, and was greater for three roles: Religious Instruction, Statutory Duties, and Role Extension. It was concluded that clergy satisfactions derived from different roles are not uniform and that churchmanship is at least as important as personality in accounting for clergy work satisfaction

Overall energy conversion efficiency of a photosynthetic vesicle

The chromatophore of purple bacteria is an intracellular spherical vesicle that exists in numerous copies in the cell and that efficiently converts sunlight into ATP synthesis, operating typically under low light conditions. Building on an atomic-level structural model of a low-light-adapted chromatophore vesicle from Rhodobacter sphaeroides, we investigate the cooperation between more than a hundred protein complexes in the vesicle. The steady-state ATP production rate as a function of incident light intensity is determined after identifying quinol turnover at the cytochrome bc1 complex (cytbc1) as rate limiting and assuming that the quinone/quinol pool of about 900 molecules acts in a quasi-stationary state. For an illumination condition equivalent to 1% of full sunlight, the vesicle exhibits an ATP production rate of 82. ATP molecules/s. The energy conversion efficiency of ATP synthesis at illuminations corresponding to 1%–5% of full sunlight is calculated to be 0.12–0.04, respectively. The vesicle stoichiometry, evolutionarily adapted to the low light intensities in the habitat of purple bacteria, is suboptimal for steady-state ATP turnover for the benefit of protection against over-illumination

Work-related psychological health and psychological type among lead elders within the Newfrontiers network of churches in the United Kingdom

Building on a series of recent studies concerned with assessing work-related psychological health and psychological type among various groups of church leaders, this study reports new data provided by 134 Lead Elders within the Newfrontiers network of churches in the United Kingdom who completed the Francis Psychological Type Scales (FPTS) together with the two scales of the Francis Burnout Inventory (FBI) concerned with emotional exhaustion and satisfaction in ministry. Compared with other groups of church leaders, Lead Elders within the Newfrontiers network of churches reported lower levels of emotional exhaustion and higher levels of satisfaction in ministry. Compared with other groups of church leaders, there was a higher proportion of extraverts among Lead Elders within the Newfrontiers network of churches. There was only a weak association between psychological type and burnout

Atomistic study of the long-lived quantum coherences in the Fenna-Matthews-Olson complex

A remarkable amount of theoretical research has been carried out to elucidate the physical origins of the recently observed long-lived quantum coherence in the electronic energy transfer process in biological photosynthetic systems. Although successful in many respects, several widely used descriptions only include an effective treatment of the protein-chromophore interactions. In this work, by combining an all-atom molecular dynamics simulation, time-dependent density functional theory, and open quantum system approaches, we successfully simulate the dynamics of the electronic energy transfer of the Fenna-Matthews-Olson pigment-protein complex. The resulting characteristic beating of populations and quantum coherences is in good agreement with the experimental results and the hierarchy equation of motion approach. The experimental absorption, linear and circular dichroism spectra and dephasing rates are recovered at two different temperatures. In addition, we provide an extension of our method to include zero-point fluctuations of the vibrational environment. This work thus presents one of the first steps to explain the role of excitonic quantum coherence in photosynthetic light-harvesting complexes based on their atomistic and molecular description.Comment: 24 pages, 6 figure

Hierarchical Equations of Motion Approach to Quantum Thermodynamics

We present a theoretical framework to investigate quantum thermodynamic processes under non-Markovian system-bath interactions on the basis of the hierarchical equations of motion (HEOM) approach, which is convenient to carry out numerically "exact" calculations. This formalism is valuable because it can be used to treat not only strong system-bath coupling but also system-bath correlation or entanglement, which will be essential to characterize the heat transport between the system and quantum heat baths. Using this formalism, we demonstrated an importance of the thermodynamic effect from the tri-partite correlations (TPC) for a two-level heat transfer model and a three-level autonomous heat engine model under the conditions that the conventional quantum master equation approaches are failed. Our numerical calculations show that TPC contributions, which distinguish the heat current from the energy current, have to be take into account to satisfy the thermodynamic laws.Comment: 9 pages, 4 figures.
