Coding and data analysis during qualitative empirical research in Practical Theology
Full text linkI dedicate this article to Prof. George Lotter, who has been instrumental in the formation of more than 90 postgraduate students in practical theological studies at the North-West University (NWU). Under his guidance, a significant amount of empirical research has been conducted. This is in line with a movement among scholars, both national and international, towards a more empirical approach in Practical Theology. It is therefore indispensable that both lecturers and students in Practical Theology should further develop their empirical research capacities. In this article, it is argued for a more systematic approach during the coding and data analysis phase of qualitative research and the article concludes with a proposed model for coding and data analysis in practical theological studies.
Kodering en data-analise tydens kwalitatiewe empiriese navorsing in Praktiese Teologie. Hierdie artikel word aan prof. George Lotter opgedra. Deur die jare was hy instrumenteel in die vorming van meer as 90 nagraadse studente in Praktiese Teologie by die Noord-Wes Universiteit (NWU). Baie empiriese navorsing het onder sy leiding plaasgevind. Dit is in ooreenstemming met die nasionale en internasionale tendens van ’n meer empiriese benadering in Praktiese Teologie. Dit is dus van die uiterste belang dat Praktiese Teologie-dosente en -studente se vaardighede in empiriese navorsing verder ontwikkel moet word. In hierdie artikel word aangetoon dat ’n meer sistematiese benadering gevolg moet word tydens die kodering en die data-analisefase van kwalitatiewe navorsing. ’n Model vir die kodering en data-analise vir navorsing in Praktiese Teologie word ook voorgestel
Practical theologians’ calling to serve in the field of gerontology
Full text linkThe South African demographic statistics echo the global trend of an ageing population. This fact poses challenges to the country’s labour supply, to health care, retirement and intergenerational relations. The elderly are faced with specific challenges such as negative views regarding older people, discrimination and prejudice based on age, changing roles, the loss of a support system when children emigrate, financial problems, abuse and neglect, emotions of fear and depression, and the struggle to find meaning in life and suffering. The field of study that concerns ageing and older adulthood is called gerontology. Joan Erber defines it as ‘the study of the biological, behavioural, and social phenomena that occur from the point of maturity to old age.’ It is an interdisciplinary field where different disciplines seek to address the problems associated with ageing. Biologists focus on the biological processes of ageing, psychologists focus on aspects like mental abilities, personality and behaviour, whilst sociologists study the social roles, group behaviour and status of older people. The question may be asked what is being done regarding the spiritual and emotional needs of the elderly. This is the niche of practical theology, as indicated by one definition of practical theology that it is ‘a place where religious belief, tradition and practice meet contemporary experiences, questions and actions and conducts a dialogue that is mutually enriching, intellectually critical, and practically transforming’ according to Pattison and Woodward. The aims of this exploratory article are (1) to investigate to what extent research in practical theology has addressed the spiritual and emotional needs of the elderly and (2) to identify opportunities where practical theology may provide service in the field of gerontology

The impact of Christian Higher Education on the lives of students and societies in Africa
Full text linkCorruption is a worldwide problem. Authors do not only agree that it should be addressed at a personal level, but they encourage everyone to become involved in the fight against corruption. For this to happen, individual transformation is a prerequisite. In this article, Chipapata, Fátima and Jacinto’s personal stories will bear witness to the potential role of Christian Higher Education (CHE) in the moral and spiritual transformation of individuals in local African communities. These three persons were extra-mural students enrolled at Hefsiba in Mozambique. That the impact of these three persons’ studies goes beyond the personal level is seen in the community in which they live and work. They consented to tell their stories starting with events before they commenced their studies, sharing experiences they had during their studies and describing how their studies impacted their lives, families, work and the community in which they live. In this article, the essence, purpose and content of CHE are addressed. It is argued that through CHE, students’ faith and education could be integrated. Apart from being competent in their professions, students would be committed to apply their competency to deal with the spiritual and material conditions of their communities. This might bring about a transformation of society.
Die impak van Christelike Hoër Onderwys op die lewens van studente en gemeenskappe in Afrika. Korrupsie is ’n wêreldwye probleem. Outeurs stem nie net saam dat dit op persoonlike vlak aangespreek moet word nie, maar hulle moedig almal ook aan om betrokke te raak in die stryd teen korrupsie. Dit kan net gebeur as individuele transformasie reeds plaasgevind het. In hierdie artikel lewer Chipapata, Fátima en Jacinto se persoonlike verhale getuienis van die potensiële waarde van Christelike Hoër Onderwys (CHO) met betrekking tot die morele en geestelike transformasie van individue in plaaslike Afrikagemeenskappe. Hierdie drie persone was buitemuurse studente van Hefsiba in Mosambiek. Die impak van hierdie drie persone se studies strek verder as bloot hul persoonlike lewens. Dit is ook sigbaar in die gemeenskap waarin hulle woon en werk. Hulle het ingestem om hul verhale te vertel, beginnende by gebeure voor die aanvang van hul studies, hul ervarings tydens hul studies en hoe hul studies hul lewens, gesinne, werk en gemeenskap beïnvloed het. In hierdie artikel word die essensie, doel en inhoud van CHO aangespreek. Daar word geargumenteer dat studente se geloof en onderwys geïntegreer word deur CHO. Studente word dus nie net toegerus vir hul professies nie, maar behoort ook toegewyd te wees om konstruktief by die spirituele en materiële nood van hul gemeenskappe betrokke te raak. Dit mag moontlik ’n transformasie van die gemeenskap tot gevolg hê

No full textThe terebratulide genus Petria Mendes, 1961 was described for a group of cryptonelloid brachiopods (Brachiopoda, Terebratulida) from the Carboniferous (Pennsylvanian) of the Amazonian region, Brazil. To our knowledge only the type species Waldheimia coutinhoana Derby, 1874 was placed in the genus. The genus name Petria Mendes, 1961 is pre-occupied by Petria Semenov, 1893, a genus in the Coleoptera family Tenebrionidae. </jats:p

Generic refinements for behavioral specifications
Full text linkThis thesis investigates the properties of generic refinements of behavioral specifications.
At the base of this investigation stands the view from algebraic specification that
abstract data types can be modeled as algebras. A specification of a data type is formed
from a syntactic part, i.e. a signature detailing the interface of the data type, and a
semantic part, i.e. a class of algebras (called its models) that contains the valid implementations
of that data type.
Typically, the class of algebras that constitutes the semantics of a specification is
defined as the class of algebras that satisfy some given set of axioms. The behavioral
aspect of a specification comes from relaxing the requirements imposed by axioms, i.e.
by allowing in the semantics of a specification not only the algebras that literally satisfy
the given axioms, but also those algebras that appear to behave according to those
axioms. Several frameworks have been developed to express the adequate notions of
what it means to be a behavioral model of a set of axioms, and our choice as the setting
for this thesis will be Bidoit and Hennicker’s Constructor-based Observational Logic,
abbreviated COL.
Using specifications that rely on the behavioral aspects defined by COL we study
the properties of generic refinements between specifications. Refinement is a relation
between specifications. The refinement of a target specification by a source specification
is given by a function that constructs models of the target specification from
the models of the source specification. These functions are called constructions and
the source and target specifications that they relate are called the context of the refinement.
The theory of refinements between algebraic specifications, with or without the
behavioral aspect, has been well studied in the literature. Our analysis starts from those
studies and adapts them to COL, which is a relatively new framework, and for which
refinement has been studied only briefly.
The main part of this thesis is formed by the analysis of generic refinements.
Generic refinements are represented by constructions that can be used in various contexts,
not just in the context of their definition. These constructions provide the basis
for modular refinements, i.e. one can use a locally defined construction in a global context
in order to refine just a part of a source specification. The ability to use a refinement
outside its original context imposes additional requirements on the construction
that represents it. An implementer writing such a construction must not use details of
the source models that can be contradicted by potential global context requirements.
This means, roughly speaking, that he must use only the information available in the
source signature and also any a priori assumption that was made about the contexts of
use.
We look at the basic case of generic refinements that are reusable in every global
context, and then we treat a couple of variations, i.e. generic refinements for which
an a priori assumption it is made about the nature of their usage contexts. In each
of these cases we follow the same pattern of investigation. First we characterize the
constructions that ensure reusability by means of preservation of relations, and then, in
most cases, we show that such constructions must be definable in terms of their source
signature.
Throughout the thesis we use an informal analogy between generic (i.e. polymorphic)
functions that appear in second order lambda calculus and the generic refinements
that we are studying. This connection will enable us to describe some properties
of generic refinements that correspond to the properties of polymorphic functions inferred
from their types and named “theorems for free” by Wadler.
The definability results, the connection between the assumptions made about the
usage contexts and the characterizing relations, and the “theorems for free” for behavioral
specifications constitute the main contributions of this thesis
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
