L. J. Du Plessis as Regsdenker
No full textThis article seeks to explain some of the outlines of the legal philosophy of L. J. du Plessis, without pretending that a meticulously coherent system of thought can be deduced from his deverse legal writings. Much rather the claim is made that his endeavours display a marked “environmental involvement", hence placing his contribution in the framework of
• the South African jurisprudential scene o f his time, and
• the mainstream o f twentieth-century Reformational (or Neo-Cahinist) thought.
Even though Du Plessis relies heavily on the Dooyeweerdian Philosophy o f the Comonomic Idea, he also shows himself to be a profoundly original thinker at the same time. The spearhead of this originality manifests itself in the way in which het intergrates a socto-eschatological view o f reality in his legal thought, to an extent unsurpassed by his like-minded contemporaries. The first part of the this article introduces Du Plessis as a jurist displaying a marked environmental sensitivity. It also attempts to contextualixe bis contributionin the field o f legal theory. The second part deals with the foundationallines i along which his legal thought had developed as well as the distinctivecharacteristics o f his contribution

Die ontwikkelingsgeskiedenis van die Vrystaat tydens die administrateurskap van J. W. J. C. (Sand) du Plessis
No full textAfrikaans: 'n Studie is gemaak oor die breë front van die ontwikkelingsgeskiedenis van
die Vrystaat vanaf 1959 tot 1969. Uit die aard van die saak is dit 'n
geweldige wye onderwerp en kon slegs dieptesnitte gemaak word rondom die
heel belangrikste fasette van die provinsiale administrasie se verpligtinge
wat in dieselfde tydvak nagekom moes word. Inderwaarheid korreleer die stof
voortdurend met mekaar en vloei dit soms ineen.
Ter wille van 'n logiese beeld is daar probeer om die fasette te skei en
afsonderlik te hanteer, hoewel dit eintlik alles onderhewig was aan 'n totale
beplanningstrategie van die Administrateur-in-Rade. Die Administrateur kon
op sigself geen beslissing op sy eie neem sonder die goedkeuring van die
Uitvoerende Komitee nie. Die gesamentlike vergadering van genoemde
betrokkenes staan bekend as die Administrateur-in-Rade. Die wye omvang van
optrede deur die administrasie op soveel verskillende terreine verleen 'n
gedrongenheid van faktore en aspekte aan die verhandeling wat dit moontlik
kan laat lyk na 'n opeenhoping van gegewens. Dit is eintlik niks anders nie
as 'n weerspieëling van die baie ysters wat die Administrateur en sy
Uitvoerende Komitee in die vuur gehad het.
Die veelheid van faktore en aspekte wat dus onder die loep geneem is, is
grootliks te wyte aan die wye spektrum van sake wat op die Administrateur en
sy personeel se sakelys was, eerder as wat dit 'ngebrek aan struktuur is.
Dit verklaar terselfdertyd waarom dit nie moontlik was om 'n deurlopende
chronologie op te bou deur die tema in verhaaltrant uit te bou nie. Daar
moes telkens sekere. dieptesnitte gedoen word van ontwikkelings wat
gelyktydig plaasgevind het, sodat die chronologie dikwels die onderspit moes
delf, ter wille van die behoud van struktuur. Die onder-struktuur van elke
hoofstuk is nietemin tematies aangepak vir sover dit enigsins moontlik was.
Baie onderhoude is gevoer ten einde die tydsklimaat en omstandighede
duidelik te verstaan. Veel meer aandag is egter verleen aan die dokumentêre
bewyse aangesien dit meer gedetailleerd, presieser en dus meer gesaghebbend
is. Uiteindelik het die dokumente en die onderhoude mekaar ryklik aangevul.
In 'n poging om die ontwikkelingsgeskiedenis van die Vrystaat sinvol uit te
bou en te evalueer, was dit telkens nodig om veralook na die periode vóór
Du Plessis se termyn as Administrateur te kyk. Daarsonder sou veel verlore
gegaan het en kon 'nobjektiewe mening kwalik gevorm word. Dit was daarom
nodig om ook na sy rol in die uitbouing van die Vrystaat te kyk in die
periode voordat hy Administrateur geword het en dit in samehang te beskou
met ontwikkeling wat plaasgevind het na hyself die leisels oorgeneem het.
Sodoende word 'nveel bevredigender beeld verkry van die persoonlike bydrae
en inisiatief wat van Du Plessis uitgegaan het om die Vrystaat in die dekade
sestig so duidelik op die pad van ontwikkeling en groei te plaas.
Die bewys hiervan lê in sy hele optrede. Die tweede en derde hoofstukke en
ook hoofstuk sewe spreek van die historiese agterstand wat deur die jare in
die Vrystaat opgebou is op die gebiede van hospitalisasie, onderwys, paaie
en natuurbewaring en die pogings wat aangewend is om dit te verander.
Hoofstuk twee gee die leser 'nbeter beeld van die spesifieke tydsgewrig en
omstandighede waaronder Du Plessis die leisels oorgeneem het.
Hoofstuk vyf handel spesifiek oor die waarde wat aan beplanning en die
kontrolering van projekte toegeken is, terwyl hoofstuk vier rondom toerisme
gebruik word om 'n unieke model as uitvloeisel van dié beplanning te
beskrywe. Hoofstuk ses, wat oor Oranjejag handel, is op sigself 'n
merkwaardige gebeurtenis in die Vrystaatse en dalk in die Suid-Afrikaanse
geskiedenis. Dit is 'n unieke voorbeeld van pionierswerk wat deur onbegrip
aan bande gelê is en daarom moeilik sy kinderskoene ontgroei het
A comparison of fatigue analysis methods for L-PBF net-shape surfaces in Ti6Al4V parts
No full textThe fatigue performance of additive manufacturing components is strongly limited by the surface topology, in particular considering the effect of the surface orientation. In the present study, Ti6Al4V laser powder bed fusion (L-PBF) net-shape specimens were printed considering four critical orientations to investigate and compare HCF fatigue properties and two different fatigue assessment methods.
Detailed X-ray Computer Tomography (XCT) allowed us to carry out numerical simulations of the 4-Point Bending test samples, by adopting the critical distance method (TCD method). Endurance limit predictions based on the most critical valleys were performed by TCD and compared to predictions made with a Fracture Mechanics model that relies on simple profile roughness parameters.
Comparison of the methods show that TCD inherently includes the shielding effect and it can better account for isolated features, while FM is more rapid and conservative
Orientation-dependent fatigue assessment of Ti6Al4V manufactured by L-PBF: Size of surface features and shielding effect
No full textThe fatigue behaviour of as-built parts produced by means of Laser-Powder Bed Fusion process (L-PBF) is primarily influenced by the presence of stress raisers on the surface, whose morphology strongly depends on the relative orientation between the surface and the build direction. This study aims to shed light into the factors representing the surface morphology that correlate with the fatigue performance of L-PBF Ti6Al4V specimens manufactured in four different orientations. A Fracture Mechanics-based model based on measurable roughness parameters was employed for the prediction of the fatigue properties in both the finite life and endurance limit regions. The fatigue model considers an initial equivalent defect corresponding to the roughness parameter Rv,max. In addition, it includes a geometric factor F accounting for the shielding present at the roots of the micro-notches which was calculated starting from profile roughness parameters determined by X-ray Computer Tomography (XCT) scans. The predicted stress–life curves show that the adoption of the maximum profile depth Rv,max and the shielding factor F yields precise life predictions considering the effect of the surface orientation

Theoretical (dis-) position and strategic leitmotivs in constitutional interpretation in South Africa
No full textThis essay takes a look at the historic restoration that bequeathed this country and its people a prototypical, justiciable Constitution. The advent of constitutional democracy in South Africa went hand in hand with an about-turn in the interpretation of enacted law-texts (including the Constitution) and a critical interrogation of certain dominant beliefs about the interpretation of law in general and enacted law in particular. Hitherto mostly unnamed or unlabelled (but not entirely alien) interpretive strategies pursued and developed by users of the Constitution are discussed, concentrating mainly on the jurisprudence of the Constitutional Court.
Central to the author's approach is an acknowledgement of the decisive actuality of an interpreter's theoretical position becoming visible through (interpretive) leitmotivs. These recur as keynote or defining ideas, motifs or topoi lending direction to specific instances of construing law. Four leitmotivs pertinent to certain constellations of events in constitutional interpretation are discussed and their applicability and utility assessed, drawing on examples from constitutional case-law. The leitmotivs are: (i) transitional constitutionalism; (ii) transformative constitutionalism; (iii) monumental constitutionalism; and (iv) memorial constitutionalism. (i) and (ii) belong together as (A) programmatic leitmotivs and (iii) and (iv) as (B) commemorative leitmotivs.
The author concludes that, although scouting out and engaging with leitmotivs call for profound reading and for text analysis of a sort with which "logical" jurists are not always too comfortable, the said endeavours have the potential to be exceptionally rewarding

Pastorale begeleiding aan die persoon met dissosiatiewe identiteitsversteuring
No full textA person with Dissociative Identity Disorder (DID) is someone who was exposed to intense trauma impacting that person’s life negatively at various levels. Although dissociative identity disorder is described as a mental disorder in the DSM-IV, there are still unresolved issues regarding the phenomenon. Assistance should take place with care and sensitivity in order to guide the person with dissociative identity disorder taking into consideration integral dimensions of personal humanity. It is submitted that guidance in this respect can therefore not be unilaterally psychological or pastoral by nature. Effective assistance to the person implies an approach where different disciplines are part of a multidisciplinary support team. The question this article explores is how pastoral counselling may contribute to this approach in guidance of the person with dissociative identity disorder. A case study is discussed in which the conclusion is made that pastoral care has an effective role in the healing process of the person with dissociative identity disorder
