The SARAO MeerKAT 1.3 GHz Galactic Plane Survey

We present the SARAO MeerKAT Galactic Plane Survey (SMGPS), a 1.3 GHz continuum survey of almost half of the Galactic Plane (251○ ≤l ≤ 358○ and 2○ ≤l ≤ 61○ at |b| ≤ 1 5). SMGPS is the largest, most sensitive and highest angular resolution 1 GHz survey of the Plane yet carried out, with an angular resolution of 8″ and a broadband RMS sensitivity of ∼10–20 μJy beam−1. Here we describe the first publicly available data release from SMGPS which comprises data cubes of frequency-resolved images over 908–1656 MHz, power law fits to the images, and broadband zeroth moment integrated intensity images. A thorough assessment of the data quality and guidance for future usage of the data products are given. Finally, we discuss the tremendous potential of SMGPS by showcasing highlights of the Galactic and extragalactic science that it permits. These highlights include the discovery of a new population of non-thermal radio filaments; identification of new candidate supernova remnants, pulsar wind nebulae and planetary nebulae; improved radio/mid-IR classification of rare Luminous Blue Variables and discovery of associated extended radio nebulae; new radio stars identified by Bayesian cross-matching techniques; the realisation that many of the largest radio-quiet WISE H II region candidates are not true H II regions; and a large sample of previously undiscovered background H I galaxies in the Zone of Avoidance

Die meting van die gelyktydige hantering van teenstrydige en dubbelsinnige inligting as kritieke eienskap in 'n verkeidenheid van beroepe.

Since very little is known about how to deal with conflicting and ambiguous information as a work attribute an attempt was made to define this particular construct and subject it to empirical research. An instrument (the in basket exercise) was developed to measure employees' efficiency in dealing with conflicting and ambiguous information. This instrument together with instruments for measuring a number of related traits were administered to 468 subjects. It was determined that the capacity to deal with conflicting and ambiguous information has a certain relationship with intelligence and sensory cognitive judgment. No relationship could be found with certain personality traits. In all probability a separate construct is indicated by this research

Bestuurstyle in die openbare en privaatsektor van die Suid-Afrikaanse volkshuishouding.

Management styles in the public and private sector of the South African economy. A questionnaire, consisting of various biographical items and a number of measuring instruments was used to determine whether a difference in management style between organizations in the public and private sector exists. A marked resemblance between the biographical profiles of managers in the public and private sectors was found. No statistically significant difference was found in people orientation in the two sectors. Managers in the private sector however, were inclined to be more authoritarian. To the degree that this phenomenon manifests itself in managerial style, a difference in the management styles of managers in the public and private sectors does exist

'n Ondersoek na die potensiaalbepaling van werknemers in die landbousektor.

An investigation into determining the potential of workers in the agricultural sector. Industrial Psychological principles and concepts are not being applied extensively in the agricultural sector. Against this background an attempt was made to scientifically identify potential and predict job performance amongst farm labourers. Using the PAQ method of job analysis, critical attributes were identified and a satisfactorily valid battery of tests was developed. The results of this study underlines the importance of the identification of the potential of farm labourers as a first step in the personnel management process. It also serves as a source of information that could be used by farmers for counselling purposes

Die opleiding van bedryfsielkundiges in Suid-Afrika.

Oor die afgelope aantal jare het bedryfsielkundiges in Suid-Afrika by verskeie geleenthede die mening gelug dat die tyd waarskynlik aangebreek het om die ontwikkeling van hul vakgebied hier te lande in oënskou te neem. Hierdie behoefte het klaarblyklik ontstaan vanweë die snelle ontwikkeling wat die bedryfsielkunde die afgelope 10 tot 15 jaar in Suid-Afrika ondergaan het, vernaamlik in die praktiese beroeps- en bedryfslewe, aan akademiese instellings en in die beoefening van die bedryfsielkunde as 'n professie

Comparação das categorias espaciais por meio de sistemas lingüístico e pictórico em pré-escolares de diferentes grupos sócio-econômico-culturais Comparison of spacial categories in preschool children by means of linguistic and pictorial methods in three different socio-economic-cultural groups

Foi investigado um sistema discriminativo relacionado à psicolingüística a ser aplicado no Programa Centro de Educação e Alimentação de Pré-Escolar (CEAPE). Optou-se por explorar a representação espacial por meio de sistemas lingüístico e pictórico. A amostra estudada foi constituída de 105 crianças de 3 a 6 anos e meio pertencentes a três grupos: do Programa CEAPE, de um grupo controle "Não-Ceapense" e de um outro de nível sócio-econômico alto da cidade de São Paulo. Estudou-se o poder discriminativo das perguntas nos três grupos de pré-escolares. Em relação às variáveis, nível sócio-econômico-cultural e estimulação, houve diferenças significativas para testes de compreensão lingüística em favor do grupo de alto nível sócio-econômico-cultural. As percentagens de categorias dominadas por 100% dos componentes dos três grupos foram, respectivamente: 41,7% (São Paulo), 30,6% (CEAPE) e, 25,0% (não CEAPE); 95% dos componentes dos três grupos dominaram, respectivamente, 50,0% (São Paulo), 47,2% (CEAPE) e 36,1% (não CEAPE) das categorias.<br>A research into a system, related to psycholinguistics, which is to be applied to a CEAPE program for preschool-age children is described. The choice fell upon spacial representation through linguistic and pictorial systems. A cross-section of ages was studied (from 3 to 6). Sample children came from 3 groups: those from a CEAPE program, a control group of children not covered by CEAPE and a high level socio-economic group from the city of S. Paulo, Brazil. The differentiating power of the items was studied in the 3 groups. With regard to socio-economic-cultural level and stimulation, significant differences in linguistic understanding to the advantage of the high level socio-economic-cultural group were observed Percentages of categories in which all subjects, answered correcty were respectively: 41.7% (S. Paulo), 30.6% (CEAPE) and 25.0% (non-CEAPE). Ninety-five percent of the members of the 3 groups gave correct answers to 50.0% (S. Paulo), 47.2% (CEAPE) and 36.1% (non-CEAPE) of the items, respectively
