Neonatal Livers: A Source for the Isolation of Good-Performing Hepatocytes for Cell Transplantation
Authors: Tolosa Laia , Pareja-Ibars Eugenia , Donato M. Teresa , Cortés Miriam , López Silvia , Jiménez Nuria , Mir José , Castell José V. , Gómez-Lechón M. José
Published: June 2013

Hepatocyte transplantation is an alternative therapy to orthotopic liver transplantation for the treatment of liver diseases. However, the supply of hepatocytes is limited given the shortage of organs available to isolate good-functioning quality cells. Neonatal livers may be a potential source alternative to adult livers to obtain good-performing hepatic cells for hepatocyte transplantation, which has not yet been explored profoundly. High-yield preparations of viable hepatocytes were isolated from 1- to 23-day-old liver donors, cryopreserved, and banked. Cell integrity and functional quality assessment were performed after thawing. Neonatal hepatocytes showed better postthawing recovery compared with adult hepatocytes, as shown by the viability values that did not differ significantly from freshly isolated cells, a higher expression of adhesion molecules (β1-integrin, β-catenin, and E-cadherin), better attachment efficiency, cell survival, and a lower number of apoptotic cells. The metabolic performance of thawed hepatocytes has been assessed by ureogenesis and drug-metabolizing capability (cytochrome P450 and UDP-glucuronosyltransferase enzymes). CYP2A6, CYP2C9, CYP2E1, and CYP3A4 activities were found in all cell preparations, while CYP1A2, CYP2B6, CYP2C19, and CYP2D6 activities were detected only in hepatocytes from a few neonatal donors. The expression of UGT1A1 and UGT1A9 (transcripts and protein) was detected in all hepatocyte preparations, while activity was measured only in some preparations, probably due to lack of maturity of the enzymes. However, isoforms UGT1A6 and UGT2B7 showed considerable activity in all preparations. Compared to adult liver, the hepatocyte isolation procedure in neonatal livers also provides thawed cell suspensions with a higher proportion of hepatic progenitor cells (EpCAM+ staining), which could also participate in regeneration of liver parenchyma after transplantation. These results could imply important advantages of neonatal hepatocytes as a source of high-quality cells to improve human hepatocyte transplantation applicability.
Mild and efficient cyanuric chloride catalyzed Pictet–Spengler reaction
Authors: Sharma Ashish , Singh Mrityunjay , Rai Nitya Nand , Sawant Devesh
Published: June 2013

A practical, mild and efficient protocol for the Pictet–Spengler reaction catalyzed by cyanuric chloride (trichloro-1,3,5-triazine, TCT) is described. The 6-endo cyclization of tryptophan/tryptamine and modified Pictet–Spengler substrates with both electron-withdrawing and electron-donating aldehydes was carried out by using a catalytic amount of TCT (10 mol %) in DMSO under a nitrogen atmosphere. TCT catalyzed the Pictet–Spengler reaction involving electron-donating aldehydes in excellent yield. Thus, it has a distinct advantage over the existing methodologies where electron-donating aldehydes failed to undergo 6-endo cyclization. Our methodology provided broad substrate scope and diversity. This is indeed the first report of the use of TCT as a catalyst for the Pictet–Spengler reaction.
Ce que « bien éduquer » veut dire
Authors: Delay Christophe , Frauenfelder Arnaud
Published: June 2013

Selon de nombreux sociologues, on assiste depuis 1970 à un mouvement de transformation des mœurs familiales caractérisées par l’émergence à la fois d’un nouveau régime familial (une famille « relationnelle » basée sur une forte affectivité où chaque partenaire jouit d’une grande autonomie) mais aussi d’un nouveau modèle de savoir éduquer (fondé sur une autorité plus souple, négociée entre parents et enfants). Or, du fait de leur diffusion sociale inégale, ces transformations des mœurs alimentent des malentendus, dans la rencontre qui se noue au quotidien entre professionnels de diverses instances éducatives et certaines familles populaires à faible capital scolaire. En se basant sur divers matériaux (entretiens qualitatifs, analyse de dossiers), cet article vise à mieux comprendre ceux-ci en montrant ce qu’ils doivent à la position sociale des acteurs en question.
Gated communities et contrôle de l'espace urbain. Un état des lieux
Authors: Porcu Manuela
Published: June 2013

Cet article traite certaines des thématiques mises en cause par la diffusion des « gated communities », complexes résidentiels privés et surveillés, dans lesquels l’accès aux non-résidents est interdit. Après une présentation des principales caractéristiques de cette typologie d’habitation, l’article établit un lien entre la diffusion des quartiers sécurisés et les changements des formes de contrôle dans les villes contemporaines. Les « gated communities » assurent la sécurité et la tranquillité des résidents à travers le gouvernement de l’espace, une surveillance constante et l’exclusion des comportements non conformes, stratégies qui semblent être toujours plus fréquentes dans la gestion des espaces urbains.
Stratégie optimale de stockage de déchets radioactifs à vie longue sous contrainte de capacité
Authors: Villeneuve Bertrand
Published: June 2013

L’article modélise un programme de gestion de déchets nucléaires à haute activité. La physique du refroidissement permet d’entreposer un certain temps un colis chaud afin d’économiser le volume de stockage définitif : en effet, les colis plus froids peuvent être davantage serrés. La durée optimale théorique d’entreposage sans contrainte est caractérisée. Les diverses contraintes (contrainte sur la capacité de stockage, contrainte sur la durée d’entreposage, contrainte sur la capacité d’entreposage) sont envisagées. Elles conduisent à des traitements très différenciés selon les millésimes.
Assurance automobile et sélection adverse dans un modèle de Choquet
Authors: Toquebeuf Pascal
Published: June 2013

Résumé L’article étudie la sélection adverse dans le cas de la demande d’assurance d’une automobile louée lorsque le critère de décision est une espérance de Choquet. L’approche adoptée de l’intégration de l’information à la décision d’assurance autorise l’utilisation d’une procédure d’induction à rebours pour déterminer l’action optimale ex ante , ce qui permet de retrouver les conclusions du modèle bayésien. En revanche, le rôle de l’ambiguïté peut être pris en compte par les capacités, ce qui n’est pas le cas avec les probabilités. Lorsque le décideur présente de l’aversion envers celle-ci, son comportement consiste à surestimer l’information si un accident s’est produit à la première étape et à la sous-estimer dans le cas contraire.
Prévention en santé et ambiguïté
Authors: Etner Johanna , Tabo Augustin
Published: June 2013

Dans cet article, nous étudions les comportements individuels de prévention face à une incertitude sur l’état de santé. Nous analysons les choix individuels de prévention primaire et de prévention secondaire lorsque la probabilité d’apparition de la maladie n’est pas parfaitement connue. Afin de distinguer l’aversion pour le risque et l’aversion à l’ambiguïté, nous utilisons le modèle de représentation des préférences proposé par Klibanoff, Marinacci et Mukerji [2005]. Nous montrons que l’aversion à l’ambiguïté incite les individus à faire plus de prévention primaire et secondaire sous l’hypothèse d’une utilité marginale de la richesse croissante avec l’état de santé.
Bulgaria's Export Prices and Pricing-To-Market Behaviour
Authors: Penkova-Pearson Emilia
Published: June 2013

L’article teste la possibilité de discrimination par les prix à l’exportation pour les industries textiles et manufacturières en Bulgarie, sur la période 1998-2008. Une estimation en panel est faite avec l’estimation d’un modèle linéaire à effets fixes. On met en évidence une discrimination dans les exportations vers l’Union européenne – où les prix des exportations sont assez stables dans la monnaie de destination – même si cette discrimination n’est pas très forte et principalement ex post. Il n’y a pas de preuve empirique que ce comportement de pricing-to-market existe en ce qui concerne les exportations vers les Balkans ou vers les nouveaux membres de l’Union européenne.

Distribution des transactions en espèces et efficacité des paiements en euros
Authors: Bouhdaoui Yassine , Bounie David
Published: June 2013

Résumé Les travaux théoriques sur l’efficacité des systèmes de divisions monétaires ( sdm ) supposent que les montants payés en espèces dans l’économie sont répartis uniformément sur un intervalle. Dans ce travail, nous exploitons une distribution empirique des transactions en espèces et nous comparons l’efficacité du sdm européen sur cette distribution et sur une distribution uniforme. Nous montrons que le degré de concurrence entre les instruments de paiement, la proportion élevée de montants arrondis et faibles dans la distribution empirique améliorent l’efficacité du sdm européen en comparaison de celle obtenue avec la distribution uniforme.
Les objets de mémoire ou la ruine au quotidien
Authors: Cuartas Pablo
Published: June 2013

Bien qu’elle soit souvent associée à de « grands lieux », la notion de ruine s’avère pertinente pour l’analyse des objets qui peuplent le « monde-de-la-vie ». Elle peut éclaircir, plus précisément, les relations que l’on établit avec des objets qui évoquent un passé révolu et réveillent la mémoire. En ce sens, on se propose d’élargir la portée herméneutique de cette notion, afin qu’elle devienne opératoire dans la compréhension d’autres vestiges, de traces autres : ces objets de mémoire qui actualisent une expérience de la ruine au quotidien.
La force des fissures
Authors: Mons Alain
Published: June 2013

Il y a une puissance du fragile qui se manifeste dans le phénomène et la question des fissures à l’œuvre dans différents domaines sensibles : la texture des villes, les arts contemporains. Celles-ci sont aussi bien matérielles que mentales, et se fondent dans un devenir-ruine propre à des territoires existentiels. Nous pouvons ressentir un tel processus dans le jeu entre l’extérieur et l’intérieur des bâtiments de certaines villes, ou avec certaines créations. Le temps se niche dans les aspérités, les traces, les détails infimes, participant d’une décomposition clandestine des structures d’un ordre. Un futur antérieur se manifeste à travers des spectralités vivantes, délicates, constituées par l’expérience des coprésences dans la sédimentation urbaine, ou bien avec une esthétique de la vacance. A contrario des modélisations systémiques ont lieu les vagabondages mentaux, les choses passagères, le trouble dont nous faisons l’expérience dans les espaces sensibles. Plus le système (urbain, visuel, médiatique, politique, économique) se clôture sur lui-même et plus les lignes de fuite prospèrent. Les surfaces hypermodernes sont perforées par des anfractuosités secrètes, la fissure devient une faille, ou un glissement de terrain. Il s’agit de rendre compte de l’imperfection du réel, d’entrapercevoir le monde en ses mouvements obscurs, selon une anthropologie singulière.
Sociologie sémantico-logique des ruines: pour une herméneutique hybride de la ruine du Web 2.0 au Web 3.0
Authors: Andrade Pedro
Published: June 2013

Le terme ruine renvoie, à la fois, à un processus social complexe et à un concept polysémique. Les ruines constituent également un phénomène qui a une nature relationnelle. Par conséquent, une étude sociologique possible se constitue à partir des deux piliers suivants : (a) des concepts interprétés en utilisant une posture sémantique à l’égard du social et du sociologique ; (b) des relations sociales de nature logique et hybride. Ce texte développe ce type de réflexion en utilisant les outils théoriques et méthodologiques construits au sein d’un paradigme sociologique nommé Sociologie sémantico-logique et à l’intérieur de l’une de ses tactiques, l’Hybridologie sociale, qui utilise en particulier un style d’interprétation désigné Herméneutique hybride. Cette méthodologie est appliquée à l’analyse de contenu et de discours de la page « Ruins » de Wikipédia, en essayant d’y extraire les sens polymorphes qui traduisent l’imaginaire subjacent à la forme sociale « ruine ».
The Role of Issue Familiarity and Social Norms: Findings on New College Students’ Alcohol use Intentions
Authors: Rimal Rajiv N. , Mollen Saar
Published: June 2013

Background

Scholars in a variety of disciplines are interested in understanding the conditions under which social norms affect human behavior. Following the distinction made between descriptive and injunctive norms by the focus theory of normative conduct, the theory of normative social behavior predicts that the influence of descriptive norms on behavior is moderated by injunctive norms, outcome expectations, and group identity. We extended the theory by testing the proposition that the influence of descriptive norms on behavior would be greater under conditions of greater issue familiarity, defined as the ease with which one can cognitively access the behavior or behavioral issue.

Design and Methods

The model was tested in the domain of alcohol consumption intentions by conducting a survey among incoming students (n=719) to a large university in the United States. Data indicated that students in the sample were well representative of the university population.

Results

The influence of descriptive norms on behavioral intentions was moderated by issue familiarity, as predicted. Familiarity was a facilitator of behavior: the influence of descriptive norms on behavioral intentions was greater under conditions of high, rather than low, familiarity. The overall model explained 53% of the variance in alcohol consumption intentions.

Conclusions

Public health interventions promoting health behaviors need to take into account the extent to which the behaviors are familiar to the target audience. The influence of norms appears to be weaker when the behavior is unfamiliar or novel. Implications for theory and interventions for reducing alcohol consumption are discussed.

Evaluering van ons volkereverhoudingssituasie in die huidige tydsgewrig
Authors: Coetzee J. H.
Published: June 2013

Suid-Afrika se kommer oor sy veiligheid en oor ’n vreedsame toekoms staan grotendeels in verband met die vrees dat die verhouding tussen die etniese komponente van sy bevolking steeds versleg. Hierdie onsekerheid is erg verhoog sedert die val van die Portugese gesag in Mosambiek en Angola. Die toenemende gewelddadige botsing tussen Swart bevrydingsgroepe en die res van die Rhodesiese bevolking tesame met die mislukkings om ’n vreedsame skikking teweeg te bring, lewer ook ’n belangrike bydrae hiertoe.
Genesis 1-3 en die Hedendaagse Gesagskrisis
Authors: Helberg J. L.
Published: June 2013

Dit gaan in ons tyd in ’n besondere mate om ’n gesagskrisis. Hierdie krisis sluit ten nouste aan by die Skrifgesag, maar raak 00k die gesag in die algemeen. Die vraag is hier van pas of ons nie dalk van die gesagskwessie te veel ’n akademiese saak maak nie. Enersyds is die gevolg van so iets dat die hele saak betreffende Skrifgesag bloot as ’n stryd tussen teoloë gesien word waarby die ander gelowiges onbetrokke is. Andersyds kan dit die gevolg hê dat daar by ons as teoloë en ander gelowiges praktiese verwerping van die Skrifgesag is hoewel ons die gesag akademies of teoreties wel erken. Daarom moet daar breër by die gesagskwessie aangesluit en dan ook sekere lyne na die Skrifgesag getrek word. Slegs ’n paar aspekte word hier na vore gebring, veral in aansluiting by Gen. 1-3, maar ook by die verdere verband van die Ou Testament.
Die roeping tot sigbaarmaking van die katolisiteit van die kerk

Published: June 2013

In hierdie studie word die klem gelê op die sigbaarmaking van die katolisiteit van die kerk. ’n Algemeen-erkende term om die saak “sigbaarmaking” aan te dui bestaan nie in Afrikaans nie. As sinonieme uitdrukkings word ook die woorde “vergestalting, gestalte gewing, sigbare realisering en sigbare verwerkliking” gebruik.

Die vraag waarvoor u opdrag ons gestel het, is: kán, en hoe kan, die diens van ouderlinge en diakens Bybels én modern wees? Dit wek dankbare vreugde dat daar met entoesiasme aandag gegee word aan die diens van ouderlinge en diakens in die kerk. Want dit maak die kerk weerbaar teen ’n dubbele gevaar wat, in omgekeerde eweredigheid, die kerk in die moderne tyd bedreig; onmondigheid van lidmate (wat ouderlinge en diakens insluit) kweek predikanteheerskappy.
Die betekenis wat kommunikasiekunde vir die prediking kan hê
Authors: Fourie H. P.
Published: June 2013

Kommunikasiekunde is een van die jongste wetenskappe wat in die area van geesteswetenskappe ontstaan het. Dit is ’n vak wat eintlik ontstaan het uit die samevoeging van verskeie vertakkings wat vandag almal as onderafdelings van die Kommunikasiekunde beskou word. Die heel oudste hiervan is die retoriek soos dit al van voor Christus af deur die Grieke geleer is. In die meer resente verlede was Joernalistiek meer as dikwels die voorloper van huidige kommunikasiekunde-departement gewees.
Die Gereformeerde Ekumeniese Sinode
Authors: Spoelstra B.
Published: June 2013

Gedurende die 20ste eeu roep aan die ander kant internasionale sendingkonferensies (1911) en die Volkebond op politieke gebied die idee van ekumenisiteit en internasionaliteit altyd sterker op. Die Britse Ryk was ’n kortstondige wêreldeenheid. Die idee van ’n internasionale Christendom bo nasionale konfessionele en kerkregtelike identifikasies of "verdeeldheid” groei deur internasionale Christenstudente-bonde, Sondagskole, Bybelgenootskappe, liefdadigheidswerk op wêreldvlak. Tegelykertyd kleur wêreldsosialisme en die idee van ’n universele mensheid die denke in baie vorme. Die "gees” van die 20ste eeu roep al sterker om praktiese en organisatoriese "eenheid”.

’n Kritiese beskouing van Deist se 'n abc van Bybeluitleg'
Authors: Lion-Cachet F. N.
Published: June 2013

Die uitlegkunde dateer al vanaf die eerste woorde wat die mens gesê het naamlik: sy sal mannin genoem word. Hy, of die skrywer moes dit dadelik verklaar: want sy is uit die man geneem. As ons dié verklaring wou tipeer sou ons kon sê dit is ’n pragtige voorbeeld van rabbynse uitleg (midrasj) want ’isjsja (met wortel: ’enoosj) en ’isj (met wortel: ’usj of’isj) het taalkundig niks met mekaar te doen nie. Maar afgesien van die vraag of Adam Hebreeus gepraat het, is daar tog ’n ooreenkoms tussen man en vrou soos, daar ’n (klank) ooreenkoms is tussen ’isj en isjsja.

Kerkorde en belydenis
Authors: Smit C. J.
Published: June 2013

Die verband tussen kerkorde en belydenis is in die Heilige Skrif vasgelê. Eersgenoemde het sy primêre grondslag in die Skrif en laasgenoemde is in sy geheel 'n weerklank van die Skrif (vgl. Bouwman, 1970: 325, 326). Die belydenis stem ooreen met die Skrif, omdat die kerk bloot die Skrif in die belydenis nasê (homologein) om sy geloof tot uitdrukking te bring.
Kerkverband ’n Gereformeerde-kerkregtelike oorsig
Authors: Du Plooy A. Le R.
Published: June 2013

Die begrip kerkverband is ’n uitdrukking waarmee die gereformeerde kerkreg dikwels opereer, en tog kom dit as sodanig nie in die Nuwe Testament voor nie (Bouwman, I, 1928, p.244; Pont, 1981, p.23). Daarenteen staan die woord kerk (ekklésia) in die Nuwe Testament besonder sentraal. Dit is feitlik vanselfsprekend dat ’n suiwere Nuwe Testamentiese kerkbegrip die voorwaarde is vir die korrekte siening van die begrip kerkverband.

Kerkreg en kerkorde in diens van die kerkregering: Oorsig oor 'n beskouing
Authors: Smit C. J.
Published: June 2013

Kerkreg is nie ’n laboratoriumwetenskap nie. Kerkreg is ’n ’wetenskap te velde’. Interessante teorieë oor die kerkreg en die kerk­ orde bly bloot van akademiese belang as dit nie ’n bruikbare basis vir die praktyk bied nie. ’n Skriftuurlike beskouing oor kerkreg en kerkorde, as ’n hegte basis vir die kerkregering, is derhalwe van primêre belang. Die ontwerp van so ’n basis het ten doel om die Woord van God oor die hele spektrum van die kerkregering te laat spreek. Op dié wyse kan ’n bydrae gelewer word om te verhoed dat kerkregtelike handelinge (veral) op meerdere vergaderings ad hoc handelinge word wat slegs afhanklik is van die insigte van individuele ‘kerkregtelike broeders’. En so kan meegewerk word om te help verhinder dat kerklike vergaderinge teësprekende kerk­ regtelike besluit neem.)

Ek vermoed dat sommige van u van my gaan verskil. Ek vra egter vriendelik dat u geduldig sal luister en die argumente in die lig van die Skrif sal weeg.

Hierdie artikel wil nie ‘wolf, wolf!’ skreeu nie. Die gevaar om dit te doen ten opsigte van ’n beweging soos die ‘New Age’, is beslis nie denkbeeldig nie. Dit is immers streng genome nie ’n ‘beweging’ nie, nog minder ’n vereniging waarby jy as lid kan aansluit. Dit is eerder ’n onsigbare lewensopvatting wat ons huise ongemerk inkom. Juis dit kan ’n mens in die versoeking bring om ’n heksejagtery op tou te sit en die ‘vyand’ agter elke deur te soek. In hierdie artikel word gepoog om die nodige nugterheid te behou.

A debate regarding the control of God over all events has lately been going on. This article attempts to indicate which light Daniel 3 :1 7,18, in the con­text of the book as a whole, sheds on understanding the supreme rule of God by combining three factors : God's omnipotence, his freedom in exer­cising his omnipotence, and his personal way of exercising his powerful­ness.
Antroposentriese prediking
Authors: Schulze L. F.
Published: June 2013

The shift of attention from the Bible text to the recipient in modern ho­miletics is i.a. due to the deep influence of some 'auxiliary sciences' on homiletics, especially linguistics, with its reception theory. The effect of this paradigm shift is illustrated by means of some examples from modern sermons and sermon-sketches. The incisive character of the paradigm shift becomes apparent when set against the background of text-oriented homi­letics of traditional reformed theology. Finally, some dogmatic and confes­sional pitfalls of modern homiletics are briefly mentioned.
Selfliefde: ’n Skrifondersoek met die oog op die omlyning van basisteoretiese perspektiewe vir die pastoraat
Authors: Kruger S. F. , Venter C. J. H.
Published: June 2013

This article deals with the pastoral problem of self-love as a destructive force within the individual himself as well as in interpersonal relations. The biblical concept of self-love is investigated in order to formulate an answer to the humanistic idea of self-love as an authoritative instruction. The investigation of these data indicates that self-love implies a limited criterion for the justification of neighbourly love. The main focus and purpose of self-love should be its instrumentality in promoting proper neighbourly love. In conclusion, guidelines are suggested for the pastoral implementation of self-love (either in the called pastor or in the pastoral object itself).
Vernuwing in gemeenskapsbelewing binne die Gereformeerde Kerke in Suid-Afrika
Authors: Vorster J. M.
Published: June 2013

Experiencing true koinonia is one of the major problems of the church today. This problem is a remnant of the modernist period in Western culture with its emphasis on rationalism. Because of the simultaneous process of urbanisation with its subculture of individualism, privatisation and alienation, modern man is not capable forming firm and lasting spiritual relations. The modern generation is a "me-generation" with the emphasis on the rights of the individual. This article explores the way in which Reformed ministry in South Africa can be renewed to address the quest for community in a post-modern environment. Attention is paid to societal factors preventing the experience of true koinonia in the contemporary church. Various proposals aimed at enhancing the true experience of koinonia are suggested - practical suggestions concerning everyday ministry and the role of the believer.
Οίκέταί (huisbediendes) in die eerste-eeuse Grieks-Romeinse samelewing
Authors: Van Wyk G. J. , Van Rensburg F. J.
Published: June 2013

This article attempts to do the foundational work for a construct of the probable socio-historic context of household servants mentioned in 1 Peter 2:18. The article provides a general perspective of the different social classes, especially the lower classes in the Graeco-Roman society during the first century A.D. It is proposed that not all slaves were part of the lowest level of the social structure and that not all Roman citizens were equal or functioned as part of the top level of the social pyramid. Many slaves were indeed household servants. Some ex­- slaves (freedmen and freedwomen), however, were also classified according to this category. It is possible and probable that some (poor) citizens and (poor) foreigners were household servants.
All-inclusive mission - A discussion of Transforming mission (1991) by D.J. Bosch
Authors: Verster P.
Published: June 2013

Bosch’s important work, Transforming mission, is still relevant in the present missiological debate. It is clear that Bosch has a comprehensive outlook on mission and that this view is all-inclusive. A question that must, however, be asked is whether this broad view of mission does not make it impossible to focus mission on the ministry of reconciliation as outlined in 2 Corinthians 5:11-21. Although it cannot be denied that Bosch also emphasises evangelism and conversion, a tendency towards socialising mission is evident in this publication. The church as an institution is not the sole agent of renewal in the community and should not exceed the limits of its very calling. The kingdom of God must come in all its glory and though mission does proclaim that, the main focus in mission still remains the ministry of reconciliation.
Amos: ’n teologie van bedreiging?
Authors: Helberg J. L.
Published: June 2013

The book of Amos contains many undertones of threat, except in the epilogue which, according to many scholars, is redactional The question thus comes to the fore whether this characteristic implies that God is seen by Amos as a God of threat for whom one can only have fear. This article, however, points out Amos’ moral justification of God's deeds. Israel's actions, on the other hand, display a self-centredness and a lack of theocentric and personal approach. Within this framework the history of salvation, especially the exodus and the conquest of the land, as well as the election, covenant and the idea of the remnant, is fossilised and God is made a captive of space, time and relations. However, Amos' proclamation implies that in reality God cannot be made captive - neither of such a religion nor of a theology of threat. Amos envisions a situation in which everything will comply with the real aim set for it/him.

'Gees' en 'Geeste' volgens die Openbaring aan Johannes
Authors: Du Rand J. A.
Published: June 2013

'Spirit' and “Spirits’ according to the Revelation to John Theologians recently started debating the possibility of systematising a so-called doctrine of the Spirit in the book of Revelation. The intention with this contribution is not to reflect on this possibility from presupposed Pauline or Johannine projections but to allow the narrative of Revelation itself to provide a perspective on the role of the Spirit in the divine eschatological activity. It has become clear that "Spirit” in the singular form denotes the activity of the Spirit implied by the act of witnessing within the churches. The expression “seven Spirits " represents the fullness of the divine Spirit in relation to God to the Lamb and to the church's witness to the outside world.

Basic theoretical starting points on the character and foundation of a scriptural based liturgy Liturgy denotes all the religious acts and activities performed by Christians when meeting God, listening to Him, and glorifying Him during the worship service and in life. Traditionally the expression “liturgy” referred to acts and activities performed during the Sunday worship service and primarily denoted the sequence of acts followed during the service. However, an etymological analysis of the concept “λειτουργία” indicates that liturgy is a dynamic action that points to the worshipping of God that flows over from the Sunday worship service into the everyday life of the Christian. Inorder to justify this paradigm shift, it is in the first instance necessary to formulate basic theoretical perspectives for the liturgy. These basic theoretical perspectives must be founded theologically, because liturgy forms a central component of man’s worship service. These perspectives must simultaneously provide an answer to the question as to how liturgy must theologically be viewed. The authors work from the viewpoint that liturgy is founded in the covenant and kingdom’s perspectives as lines ofrevelation.
Besinning oor die diakonale dienswerk na aanleiding van Handelinge 6:1-7
Authors: Breed G. , Breed D.G.
Published: June 2013

Reflection on diaconal service in relation to Acts 6:1-7 Acts 6 is traditionally considered as the description of the origin of the special service of deaconship. The essence and duty of diaconal service is inferred from Acts 6:1-7; it is the service responsible for the care of the poor and promotion of mutual support and love in the church. This article re-examines Acts 6. It investigates whether this text truly describes diaconal service and what it conveys about the content and essence of the seven’s service. This study shows that Acts 6 does not describe the institution of a special service (office) and that the content and essence of the special diaconal service cannot be derived from this text. Acts 6:1-7 is a description of the dynamic work of the Holy Spirit within the church, related to the difficulties that arise with service (διακονία) due to rapid growth.
The Gospel of John’s perception of ethical behaviour
Authors: Van der Watt J.G.
Published: June 2013

Johannine ethics have proven to be a problematic and challenging area of research. In this article the way in which the author of the Gospel of John defines ethical actions are explored. What does he describe as the works of God and what is really good, according to him? The conclusion is that the analytical categories for treating the ethics in the Gospel of John should be broadened.
Van Calvinisme tot eksistensialisme1: ’n teologiese gesprek met André P. Brink met verwysing na sy memoirs
Authors: Van Wyk J.H.
Published: June 2013

From Calvinism to existentialism: a theological discussion with André P. Brink with reference to his memoirsIn this article the author attempts to develop a theological discussion with the well-known and world-famous writer André P. Brink, on the topics of Calvinism and existentialism. The question at stake is why Brink, who grew up in a South African Calvinist milieu, which was reinforced by his studies at the Potchefstroom University for Christian Higher Education, turned his back on Calvinism and wholeheartedly embraced existentialism during his study in Paris. Why was Potchefstroom exchanged for Paris? Why was Christ replaced by Camus? Did Brink thoroughly compare Calvinism with existentialism or was his decision taken precipitately? This is the fascinating question which the author tries to unravel in this investigation.
Die filosofiese filter
Authors: Schulze L F.
Published: June 2013

’n Filter is ’n opvanger. Dit kan dien as ’n suiweraar wat die onsuiwerhede in vog of water opvang en terughou. Dit kan egter ook dien om ligstrale van ’n bepaalde golflengte op te vang en weg te hou van die oë of van die lens van ’n kamera. Hierdeur word die beeld of omgewing wat ek sien of fotografeer, gekleur. Ons gebruik die woord filter hier in lg. sin, hoewel die meeste mense dit nie as sodanig wil sien of erken nie, maar meen om dit bloot as suiweraar te gebruik.
Kerk en kerkverband
Authors: Van der Walt J. J.
Published: June 2013

Die vraag na die verhouding van kerk en kerkverband staan sentraal in die kontrovers tussen die verskillende denominasies. Die weg na die ware kerk kan in die doolhof van diskussies, soms erg skolasties en filosofies, alleen gevind word deur ook in die vraagstukke van die kerkreg noukeurig en gehoorsaam te luister na God se Woord.

Published: June 2013

Die verklaring van die 29 alcademici oor die kleurlingvraagstuk het oor die algemeen sterk afwysende reaksie uitgelok van sommige politici, ministers en politieke party-koerante. Vir my was hierdie reaksie nie heeltemal onverwags nie.
Hoeveel persent is die mens verantwoordelik?

Published: June 2013

Ek voel my tog gedronge om in alle beskeidenheid enkele opmerkings te maak oor die artikel van my vriend ds. Ph. Snyman (vgl. In die Skriflig, Jaargang 6, nr. 23, Sept. 1972). Daar staan mooi dinge in sy artikel oor die Dordtse Leerreëls en die opkoms van die moderne humanisme met hul bevraagtekening van die Konfessie.
Geregtigheid en liefde in ons volkereverhoudinge
Authors: Coetzee J. H.
Published: June 2013

Terwyl ek die Hoofbestuur van die G.T.V. bedank vir die uitnodiging om die jaarlikse samekoms toe te spreek oor dié besondere onderwerp, behoort dit terselfdertyd duidelik te wees dat ek my nie die kennisagtergrond en geskooldheid van ’n opgeleide teoloog mag toeëien nie. Ek sien my taak hoogstens as ’n gesprek van ’n lidmaat van die Gereformeerde Kerk met predikante en teoloë van dié kerkverband.
Pastorale psigologie — ’n Toekomsperspektief
Authors: Prins S. J.
Published: June 2013

In Amerika het die pastorale psigologie groot vooruitgang gemaak. In Suid-Afrika egter voer dit ’n sukkelbestaan met die gevaar om dood te loop. Vra mens na die rede hiervoor, moet dit waarskynlik gesoek word in verkeerde beklemtoning. Daar word naamlik te veel klem gelê op die psigoterapeutiese komponent daarvan, met die gevaar dat dit die sakrale karakter van die pastoraat heeltemal sal verdring.

Eerder as om ’n samevatting van my proefskrif' te gee, wil ek in die bestek van enkele paragrawe sommige van die vernaamste bevindings probeer aanstip. Die eintlike bydrae lê in hoofstuk 3: ‘Die Skopus van die Heilige Skrif’. Na my wete is dit die eerste sistematiese ondersoek na ’n begrip wat in die huidige Skrifdiskussie ’n sentrale rol speel.

Canonical vector heights on $K3$ surfaces – A nonexistence result
Authors: Kawaguchi Shu
Published: June 2013

A. Baragar introduced a canonical vector height on a

K3

surface

X

defined over a number field, and showed its existence if

X

has Picard rank two with infinite automorphism group. In another paper, A. Baragar and R. van Lujik performed numerical computation on certain

K3

surfaces with Picard rank three, which strongly suggests that, in general, a canonical vector height does not exist. In this note, we prove this last assertion. We compare the set of periodic points of one automorphism with another on certain

K3

surfaces.
Birkhoff normal form for the nonlinear Schrödinger equation
Authors: Craig Walter , Selvitella Alessandro , Wang Yun
Published: June 2013

This paper is intended to highlight the differences between the nonlinear Schrödinger equation (NLS) posed on a compact manifold (such as a torus

\mathbb T^d

) in contrast to being posed on noncompact regions such as on all of

\mathbb R^d

. The point is to indicate a number of specific facts about the behavior of solutions in the former situation, in which they have the possibility for recurrence, and the latter, in which solutions have the tendency to disperse. This is the topic of the short article by McKean [8], in which the issue of resonance for partial differential evolution equations is discussed. The aspect of this question that we describe in the present paper is that there are different normal forms for these two cases, which rephrases the question as to which of the nonlinear terms are the resonant terms, and what is the appropriate Birkhoff normal form for the NLS. We show that, at least in a neighborhood of zero of an appropriate Hilbert space, the fourth order Birkhoff normal form transformation for the NLS equation is able to eliminate all of the nonresonant terms of the Hamiltonian, and as well, all of the resonant terms. The result is a prognosis, to the negative, for the formal theory of wave turbulence for Hamiltonian partial differential equations posed in Sobolev spaces over

\mathbb R^d

.

The Value of an Allotment Group for Refugees
Authors: Bishop Ruth , Purcell Elizabeth
Published: June 2013

Introduction:

Refugees experience a number of difficulties when settling in the United Kingdom and may be faced with occupational injustice due to their restricted occupational engagement. This study explores the value of an allotment group for refugees of working age, aiming to explore the role of horticulture and the social environment on health, wellbeing and social inclusion.

Method:

This was an exploratory study using qualitative methodology based on ethnographic principles. Data collection included observation of the group, semi-structured interviews with five participants, with four of these participants also taking part in photo-elicitation interviews. Data analysis involved using a ‘framework’ approach to produce three themes and associated sub-themes.

Findings:

Analysis identified firstly gardening as a meaningful activity; secondly, the importance of the social environment and, lastly, the value of occupational engagement for refugees. Further theoretical analysis led to the conclusion that these themes linked to the dimensions of occupation: doing, being, belonging and becoming.

Conclusion:

The findings identify how occupational engagement can have a positive impact on the health and wellbeing of refugees, specifically with the use of social and therapeutic horticulture.

Lessons Learned for Collaborative Clinical Content Development
Authors: Bavuso K. , Zuccotti G. , Rocha R.A. , Collins S.A.
Published: June 2013

Background: Site-specific content configuration of vendor-based Electronic Health Records (EHRs) is a vital step in the development of standardized and interoperable content that can be used for clinical decision-support, reporting, care coordination, and information exchange. The multi-site, multi-stakeholder Acute Care Documentation (ACD) project at Partners Healthcare Systems (PHS) aimed to develop highly structured clinical content with adequate breadth and depth to meet the needs of all types of acute care clinicians at two academic medical centers. The Knowledge Management (KM) team at PHS led the informatics and knowledge management effort for the project.

Objectives: We aimed to evaluate the role, governance, and project management processes and resources for the KM team’s effort as part of the standardized clinical content creation.

Methods: We employed the Center for Disease Control’s six step Program Evaluation Framework to guide our evaluation steps. We administered a forty-four question, open-ended, semi-structured voluntary survey to gather focused, credible evidence from members of the KM team. Qualitative open-coding was performed to identify themes for lessons learned and concluding recommendations.

Results: Six surveys were completed. Qualitative data analysis informed five lessons learned and thirty specific recommendations associated with the lessons learned. The five lessons learned are: 1) Assess and meet knowledge needs and set expectations at the start of the project; 2) Define an accountable decision-making process; 3) Increase team meeting moderation skills; 4) Ensure adequate resources and competency training with online asynchronous collaboration tools; 5) Develop focused, goal-oriented teams and supportive, consultative service based teams.

Conclusions: Knowledge management requirements for the development of standardized clinical content within a vendor-based EHR among multi-stakeholder teams and sites include: 1) assessing and meeting informatics knowledge needs, 2) setting expectations and standardizing the process for decision-making, and 3) ensuring the availability of adequate resources and competency training.

Science and Technology Parks in the Age of Open Innovation. The Finnish Case
Authors: Nicola Bellini  , Jukka Teräs  , Håkan Ylinenpää
Published: June 2013

The new emphasis on technological platforms, related variety, smart specialization etc. is leading to a substantial (although still incomplete) revision of established conceptual frameworks of the regional innovation systems, including the ‘cluster’ approach. At the same time, open innovation, as the emerging paradigm in the business literature on innovation, has proved to be a powerful concept, to be used both for analytical purposes and in order to design effective strategies for innovative companies. The role and development of Science and Technology Parks (STP) in Finland (one of the most dynamic countries in this respect), can be analysed to assess how the concept of ‘open innovation’ has been accepted and operationalized in the management of Finnish STPs.
