Abstract: Treatment of chemical addiction includes preparation for treatment, formal treatment and aftercare. The latter appears to be a neglected area in service delivery to chemically addicted adolescents, contributing to the high relapse potential following treatment. The current qualitative study aimed at both exploring and describing the aftercare needs of chemically addicted adolescents. The chemically addicted adolescents included in this study received in-patient treatment as well as aftercare, but nonetheless experienced a relapse; necessitating further in-patient treatment. Purposive sampling was implemented to recruit 31 participants between the ages of 14 and 20 years. The sample size was determined by data saturation. Data for this exploratory, descriptive and contextual study were collected by means of narrative inquiry. Tesch’s framework for qualitative data analysis was employed and data verification was conducted through Guba’s model. The findings illustrated a need to attend to adolescents intrapersonal and interpersonal as well as environmental needs following treatment. The results can provide service providers with focus areas to be included in aftercare services to these adolescents. Die behandeling van chemiese afhanklikheid sluit die voorbereiding vir behandeling, formele behandeling en nasorg in. Laasgenoemde blyk ‘n afgeskeepte area te wees in die lewering van dienste aan chemies-afhanklike adolessente, wat bydra tot die ho terugvalpotensiaal wat op die behandeling volg. Hierdie kwalitatiewe studie was daarop gerig om die nasorgbehoeftes van chemies-afhanklike adolessente te verken, sowel as te beskryf. Die chemies-afhanklike adolessente wat by hierdie studie ingesluit was het vantevore beide binnepasi ntbehandeling en nasorg ontvang, maar ten spyte hiervan teruggeval; wat verdere binnepasi ntbehandeling genoodsaak het. Doelbewuste steekproefneming is ge mplementeer om 31 deelnemers tussen die ouderdomme van 14 en 20 jaar te werf. Die steekproefgrootte was deur middel van data versadiging bepaal. Data vir hierdie verkennende, beskrywende en kontektuele studie is versamel deur middel van narratiewe ondersoek. Tesch se raamwerk vir kwalitatiewe data-analise is toegepas en dataverifikasie is uitgevoer aan die hand van Guba se model. Die bevindings illustreer ‘n behoefte om intrapersoonlike en interpersoonlike, asook omgewingsbehoeftes wat op behandeling volg, aan te spreek as deel van nasorg. Die resultate kan diensleweraars van fokusareas voorsien wat ingesluit kan word in nasorgdienste aan hierdie adolessente.
Terrestrial ground temperature variations in relation to solar magnetic variability, including the present Schwabe cycle  [PDF]
C. de Jager, H. Nieuwenhuijzen
Natural Science (NS) , 2013, DOI: 10.4236/ns.2013.510136
Abstract: We study the influence of solar activity on climate by investigating the relation between the long-term components of the total magnetic fluxes of both the equatorial and polar fields of the sun and the average terrestrial ground temperature. This is done for the period 1610 (beginning of systematic sunspot observations) till present with an extrapolation to 2015. It is found that from 1610 till about the first half of the 20th century the variation of the long-term average terrestrial ground temperatures is chiefly due to the variation of solar activity, with seemingly random, non-solar residuals. Around 2007, after the Grand Maximum of the 20th century, solar activity, after having gone through a remarkable transition period (~2005 to ~2010), entered into another Grand Episode. That Episode started with the present solar cycle, in shape comparable to the equally weak Schwabe cycle #14. The transition period, in combination with the present low Schwabe cycle causes that the solar contribution to the total terrestrial temperature variation is small during the on-going decade. It results in a slowing down of the rise of temperature after ~2005.

Investigation of the Psychological factors determining the Magnitude of Auditory Sensation
L. C. De Jager
South African Journal of Industrial Psychology , 1975, DOI: 10.4102/sajip.v0i0.269
Abstract: This research deals with some psychological factors that may influence the determination of the magnitude of auditory sensation or pure loudness. Several factors and their influences are discussed. 17 Male and 3 female subjects between 18 and 26 years of age were tested under several different experimental conditions using the method of constant stimuli. Results are discussed in terms of both future research and implications for industry. Opsomming Twintig toetslinge, 17 mans en 3 dames, tussen die ouderdomme 18 en 26 jaar is onder verskillende eksperimentele situasies getoets om die invloed van 'n aantal sielkundige faktore op die bepaling van luidheid te bepaal. Die metode van konstante stimuli is gebruik om die luidheidspeil onder die verskillende eksperimentele situasies te verkry. Die resultate van die ondersoek word bespreek in terme van toekomstige navorsing op hierdie gebied asook die implikasies wat dit vir die bedryf inhou.
Die ontwikkeling van 'n instrument vir die meting van die konstruk sielkundige diepte-orientasie
L. C. De Jager
South African Journal of Industrial Psychology , 1981, DOI: 10.4102/sajip.v0i0.327
Abstract: The development of an instrument (the RD-Depth Questionnaire, Form B) for measuring the construct psychological depth orientation is discussed. Results show that the questionnaire has satisfactory internal consistency and that the items of the questionnaire in general measure the same characteristic. Further research is needed to refine and improve the questionnaire until it meets all the psychometric requirements of a good measuring instrument. Opsomming Die ontwikkeling van 'n instrument (die RD-Diepte Vraelys, Vorm B) vir die meting van die konstruk sielkundige diepteori ntasie word bespreek. Resultate dui daarop dat die vraelys bevredigende interne bestendigheid toon en dat die items van die vraelys oor die algemeen dieselfde eienskap meet. Verdere navorsing word egter nog vereis om die vraelys te verfyn en te verbeter sodat dit aan al die psigometriese vereistes van 'n goeie meetinstrument sal voldoen.
Die meting van sistematiese tydorientasie as 'n sielkundige konstruk van Beroepsgedrag
J. I. De Jager
South African Journal of Industrial Psychology , 1985, DOI: 10.4102/sajip.v0i0.366
Abstract: Research on systematic time orientation as described by Augustyn (1978) was done in order to develop a personality description of a person with such a time orientation style and to develop a refined measuring instrument for systematic time orientation. Results show that the developed questionnaire has an acceptable internal consistency and that it can be considered a refined instrument for measuring systematic time orientation. Opsomming Met hierdie navorsing is gepoog om 'n persoonsbeeld van 'n individu met ‘n sistematiese tydori ntasiestyl saam te stel, en om 'n verfynde instrument vir die meting van sistematiese tydori ntasie te ontwikkel. Resultate toon dat die vraelys wel 'n bevredigende interne bestendigheid het en ook as ‘n verfynde instrument vir die meting van sistematiese tydori ntasie beskou kan word.
Die meting van sielkundige diepte-orientasie: 'n Verdere verfyning en omlyning
L. C. De Jager
South African Journal of Industrial Psychology , 1987, DOI: 10.4102/sajip.v13i2.462
Abstract: The measurement of psychological depth orientation: a further refinement. As a result of the psychometric weaknesses of the RD-Depth Questionnaire (de Jager, 1979) for measuring psychological depth orientation an effort was made to develop a new instrument. In the present study a new instrument with outstanding psychometric properties (the DJ-Behaviour Questionnaire) was successfully developed and evaluated. As a further step in construct validation the instrument was also successfully correlated with other variables. Reccomendations for future research are made. Opsomming As gevolg van die psigometriese tekortkominge van die RD- iepte Vraelys (de Jager, 1979) vir die meting van sielkundige diepte-orientasie, is 'n poging aangewend om 'n nuwe instrument te ontwikkel. In hierdie ondersoek is daar dan ook daarin geslaag om 'n instrument met besonder bevredigende psigometriese eienskappe (die DJ-Ge- dragsvraelys) te ontwikkel. As 'n verdere stap in konstrukvalidering is die instrument ook suksesvol met ander veranderlikes gekorreleer. Aanbevelings vir toekomstige navorsing word gemaak.
Sielkundige diepte-orientasie: 'n Koseptuele omskrywing en verfyning
L. C. De Jager
South African Journal of Industrial Psychology , 1980, DOI: 10.4102/sajip.v0i0.323
Abstract: An effort is made to define and describe on a conceptual basis the psychological depth dimension of the 4-dimensional classification theory of human behaviour (Raubenheimer, 1978) as a construct of human behaviour. Cognitive and non-cognitive behavioural correlates of different cognitive styles are also related on a logical basis to the construct psychological depth orientation. Opsomming Die sielkundige diepte-dimensie as konstruk van menslike gedrag in die 4-dimensionele klassifikasieteorie van menslike gedrag (Raubenheimer, 1978) word konseptueel omskryf en afgebaken. Kognitiewe en nie kognitiewe gedragskorrelate van verskillende kognitiewe style word ook op 'n logiese wyse aan die konstruk sielkundige diepte-ori ntasie gekoppel.
