Prophetic witness in weakness: A response to Prof Robert Vosloo from a Pentecostal perspective
No full textIn his article about the prophetic witness of the church, Vosloo emphasises the necessity that it should always be done in solidarity with society to represent the perspective of weakness as a form of performative resistance. In response to Vosloo, this article utilises a Pentecostal perspective to think about the church’s prophetic witness. ‘Prophecy’ means something else for Pentecostals. They hold a non-cessationist or continuationist approach to the Bible, implying that they are committed to a Spirit-centred, miracle-affirming, praise-oriented version of Christian faith where prophets still play an important role. The role of the prophet is defined in two ways: bringing a word from God related to the present situation, and engaging in prophetic politics to help solve society’s challenges

Die verband tussen 'n geslagshormoonwanverhouding en depressie by vroue
No full textEnglish: This study was directed by the following three specific objectives:
- Firstly, to present a theoretical synthesis from the literature, which would
explain the possible relation between depression and a sex hormone
imbalance from a medical hypnoanalytical perspective.
- Secondly, to determine whether a statistically significant correlation exists
between dysthymia and depression respectively (in terms of two scales of
the Millon Clinical Multiaxial Inventory III, namely scales D and CC) and
the individual serum values of women's testosterone, progesterone and
estradiol (in their oestrogen, progesterone or menopausal phases
classified separately or considered jointly).
- Thirdly, to determine whether the three relative imbalances of the sex
hormones, namely between testosterone and progesterone, between
oestrogen and progesterone, and between testosterone and oestrogen, in
terms of the Maartens profile (Maartens, 1994), displays a statistically
significant correlation with dysthymia and depression in terms of the
counts obtained on the scales of the above-mentioned psychometric
measuring instrument. Subsequently, it was determined which statistically
significant correlation is most significant.
In order to achieve these objectives, the following methodology was
followed:
- Objective 1: A relevant literature survey was conducted.
- Objectives 2 and 3: The first 60 women who presented a mild or serious
degree of depression in the clinical opinion of Dr. H. Vosloo (a medical
practitioner) or the researcher, were selected randomly for the purpose of
the research. If they were prepared to participate in the research, they
were requested first to complete the information sheet by providing their
personal details and then to give written permission that their hormone
profile and psychometric data may be used in the research on an
anonymous basis. Subsequently they were requested to complete the
Beck Depression Inventory (Short Form) and the Millon Clinical Multiaxial
Inventory III and to have blood samples taken at specific pathologists. The
pathologists then sent their results to Dr. Vosloo, who interpreted it further.
At the same time, all the mentioned psychometric measuring instruments
were scored and interpreted by the researcher himself and the results of
the Maartens profile were obtained from Dr. Vosloo.
The results related to each objective, which were obtained in the abovementioned
methodological manner, can be summarised as follows for each
objective:
- Objective 1: It was shown successfully from the literature that nonoverwhelming
chronic stress stimulates B-endorphin secretion and
testosterone secretion, but as soon as the stressor is conceptualised as
overwhelming, it has a testosterone-inhibiting function as a result of the
still-rising endorphin levels. It was also demonstrated successfully from
the literature, in terms of the medical hypnoanalytical model, that the first
time an individual is exposed to the stressor, it is called the Initial
Sensitising Event. The second time the individual is exposed to a similar
stressor is called the Symptom Producing Event, and the third time it is
called the Symptom Intensifying Event. After the third event the stressor is
conceptualised as overwhelming in terms of the triple allergenic theory,
and the stressor can therefore exert a testosterone-inhibiting function,
which explains the presentation of depression in terms of medical
hypnoanalysis.
- Objective 2: The research results of this objective indicated that there is
no statistically significant relation between depression and the individual
serum values of the three primary sex hormones.
- Objective 3: In the case of this objective, the research results indicated
that a relatively low testosterone level (in comparison to the other possible
hormone-imbalance classification categories in terms of the Maartens
profile) displays the strongest statistically significant relation (p < 0,05)
with dysthymia and depression.
On the basis of the research results of this investigation, the researcher can
therefore conclude that the traditional view of a hormone imbalance (in terms
of the deviation of a patient's individual serum values from the mean values)
has it's limitations, because this before mentioned hormone imbalance cannot
be conceptualised as a cause for depression. A sex hormone imbalance in
terms of the Maartens profile can, however, perform such an etiological role.Afrikaans: Hierdie studie is gerig deur die volgende drie spesifieke doelstellings:
- Eerstens, om vanuit die literatuur 'n teoretiese sintese aan te bied, wat die
moontlike verband tussen depressie en 'n geslagshormoonwanverhouding
vanuit 'n mediese hipnoanalitiese perspektief verklaar.
- Tweedens, om te bepaal of daar statisties beduidende korrelasies tussen
distimie en depressie onderskeidelik (in terme van twee skale van die
Milion-kliniese-meervoudige-as-inventaris-III, naamlik skale D en CC) en
die individuele serumwaardes van vroue se testosteroon, progesteroon en
estradiol (in hul estrogeen-, progesteroon- of menopousale fase
afsonderlik geklassifiseer of gesamentlik beskou) is.
- Derdens, om te bepaal of die drie relatiewe wanverhoudings van die
geslagshormone, naamlik tussen testosteroon en progesteroon, tussen
estrogeen en progesteroon, en tussen testosteroon en estrogeen, in terme
van die Maartens-profiel (Maartens, 1994), statisties beduidend met
distimie en depressie korreleer in terme van die tellings behaal in die skale
van die vermelde psigometriese meetinstrument. Daarna is bepaal word
watter een van die statisties beduidende korrelasies die beduidendste is.
Ten einde aan die doelstellings te beantwoord, is die volgende metodologie
gevolg:
- Doelstelling 1: 'n Toepaslike literatuurstudie is onderneem.
- Doelstelling 2 en 3: Die eerste 60 vroue, wat volgens die kliniese
indrukke van dr. H. Vosloo ('n mediese praktisyn) of die navorser, met 'n
matige of ernstige graad van depressie gepresenteer het, is vir die doel
van die navorsing ewekansig geselekteer. Indien hulle bereid was om aan
die navorsing deel te neem, is hulle versoek om eers die inligtingstuk te
voltooi deur hulle persoonlike gegewens daarop te verstrek en dan
skriftelik toestemming te verleen dat hul hormoonprofiel en psigometriese
data anoniem in die navorsing betrek mag word. Daarna is hulle versoek
om die Verkorte Beck-depressieskaal en die Millon-kliniese-meervoudigeas-
inventaris-III te voltooi en om bloedmonsters by spesifieke patoloë te
laat neem. Die patoloë het voorts hul resultate aan dr. Vosloo versend,
wat dit verder geïnterpreteer het. Terselfdertyd is al die vermelde
psigometriese meetinstrumente deur die navorser self nagesien en
geïnterpreteer en is die resultate van die Maartens-profiel van dr. Vosloo
verkry.
Die resultate ten aansien van elke doelstelling, wat op die bovermelde
metodologiese wyse nagevolg is, kan vir elke doelstelling as volg saamgevat
word:
- Doelstelling 1: Daar is suksesvol uit die literatuur aangedui dat nieoorweldigende
langdurige stres, ~-endorfiensekresie en testosteroonsekresie
stimuleer, maar sodra die stressor as oorweldigend gekonseptualiseer
word, dit as gevolg van die steeds stygende endorfienvlakke 'n
testosterooninhiberende funksie het. In terme van die mediese
hipnoanalitiese model is daar ook suksesvol uit die literatuur aangedui dat
die eerste keer dat 'n individu aan die stressor blootgestel word, dit die
inisiële sensitiserende gebeurtenis genoem word. Die tweede keer as hy
aan 'n soortgelyke stressor blootgestel word, word dit die simptoomproduserende
gebeurtenis genoem en die derde keer die simptoomintensiverende
gebeurtenis. Na die derde gebeurtenis word die stressor in terme
van die drievoudige allergeenteorie as oorweldigend gekonseptualiseer en
kan die stressor dus 'n testosterooninhiberende funksie uitoefen, wat die
presentering van depressie in terme van die mediese hipnoanalise
verklaar.
- Doelstelling 2: Die navorsingsresultate van die doelstelling het getoon
dat daar geen statisties beduidende verband tussen depressie en die
individuele serumwaardes van die drie primêre geslagshormone is nie.
- Doelstelling 3: Die navorsingsresultate van die doelstelling het getoon
dat 'n relatiewe lae testosteroonvlak (in vergelyking met die ander
moontlike hormoonwanbalans-klassifikasiekategorieë in terme van die
Maartens-profiel) die sterkste statisties beduidende verband (p < 0,05) met
distimie en depressie het.
Die navorser kan dus konkludeer dat die tradisionele siening van 'n
hormoonwanbalans (in terme van die afwyking van 'n pasiënt se individuele
serumwaardes van die gemiddelde waardes) volgens die navorsingsresultate
van die onderhawige ondersoek nie as 'n oorsaak van depressie gekonseptualiseer
kan word nie. 'n Geslagshormoonwanverhouding in terme van die
Maartens-profiel kan egter wél sodanige etiologiese rol vertolk

A DFT computational study of phosphine ligand dissociation versus hemilability in a Grubbs-type precatalyst containing a bidentate ligand during alkene metathesis
No full textUsing density functional theory, the metathesis reaction of 1-octene in the presence of a Grubbs-type ruthenium alkylidene complex bearing a chelating pyridinyl alcoholate ligand, [RuCl(L)(O∧ N)( = CHPh)] (L = H2IMes or PCy3, O∧ N = 1-(2′-pyridinyl)cyclohexan-1-olate)), was investigated. The complete geometry optimisation and activation energy of various activation steps in the dissociative mechanism were performed at the GGA-PW91/DNP level of theory using Accelrys Materials Studio® 4.0. Two possible precatalyst initiations were explored, i.e. the dissociation of the labile N-atom of the O∧ N-ligand as well as the dissociation of ligand L, due to the belief that ruthenium-catalysed metathesis reactions proceed through 14-electron intermediates. The formation of the catalytically active heptylidene species is kinetically favoured for both the first- and second-generation chelating complexes. The computational results are in agreement with the experimental results obtained with NMR for the second-generation system. The computational results suggest that both phosphine ligand dissociation and hemilability may play a role in the metathesis reaction with the first-generation syste
A generic approach to integrating energy related data
No full textThe energy management processes of mines and industrial plants differ because of the specialised processes used for mining or production. Therefore, energy management systems typically provide users with specialised tools and reports to facilitate the ongoing energy management process. However, an energy management system that does not consider energy related data does not provide a comprehensive cross-industry solution. A system that is capable of comparing energy data with related data such as production, budget and cost data presents further opportunities for comprehensive energy management. The logistics of data retrieval and management from a wide variety of data sources is, however, problematic because of diverse data formats and modes of access. These data sources range from databases to document based reports and accounts. Energy personnel on different authority levels require access to different data to fulfil their specific role in the energy management process. Furthermore, individual energy personnel have their own preferences regarding the type and graphical representation of data. Therefore, this paper presents a generic approach to integrating data required for comprehensive energy management. The results obtained from practical implementations also proved the approach's adherence to the requirements of different industries. These initial implementations only included electrical energy and related data, while future implementations will include data for other energy sourceshttp://www.ieee.org/conferences_events/conferences/xplore_conference_proceedings.htm
