ROLE OF CAREER GUIDANCE IN THE PREPARATION OF SECONDARY SCHOOL PUPILS FOR TERTIARY EDUCATION IN LUANSHYA DISTRICT, ZAMBIA

The purpose of this study was to investigate the role of career guidance in the preparation of secondary school pupils for tertiary education in Luanshya district, Zambia. A descriptive research design supported by qualitative and quantitative approaches were used. A total of 56 questionnaires were distributed to head teachers and career guidance teachers at 12 schools in Luanshya District. Out of which a total of 51 were returned, with 5 not being returned by head teachers amongst the twelve schools used in the study. The questionnaire contained closed and a few open-ended questions which were scaled with a Likert scale and were analyzed quantitatively and qualitatively. The qualitative questions were analyzed thematically, emerging themes were coded and descriptively presented thereafter. Quantitative responses were analyzed through quantitative method involving coding and analyzing using charts, frequencies and percentages through a computer program referred to as Statistical Package for Social Science (SPSS version 22). The study revealed that, although career guidance has a significant positive role to play in the preparation of secondary school pupils for tertiary education, findings obtained from the study have revealed that career guidance was aimed preparing secondary school pupils for tertiary education although had a number of challenges. The number of pupils currently using these services on a weekly basis was very low, and the resources needed in the provision of these services are also lacking. Nevertheless, in spite of these hurdles being faced by the career guidance departments in the schools, there have been significant improvements in preparation of students for tertiary education. These significant improvements were in terms of behaviour; reduced pregnancy rates and improved academic performance, a major positive and a stepping stone for encouraging more pupils to utilise these services and enter tertiary education. The study recommended that head teachers ensure all teachers participate in spearheading campaign and information sharing on career guidance. Collaboration among teachers, career guidance teachers and counsellor in tertiary education should take pace, in order to easily identify pupils who faced challenges. Lastly, government of Zambia through the Ministry of General Education ensure that they equip schools with the requisite resources needed in order for the career guidance departments to operate in accordance with the expectations.

Penghambatan Serangan Sclerotium Rolfsii Penyebab Rebah Kecambah pada Kedelai dengan Bakteri Kitinolitik

The inhibition of Sclerotium rolfsii as causal agent of soybean damping off by using chitinolytic bacteria were studied in Laboratory of Observation Pest and Disease UPT-BPTPH 1 and Laboratory of Microbiology, Department of Biology, Faculty of Mathematics and Natural Sciences, University of Sumatera Utara, Medan. The aim of this research was to investigate the ability of chitinolytic bacteria to inhibit the growth of S. rolfsii. Six isolates of chitinolytic bacteria were used in this study. The inhibition zone between colony of the bacteria and the fungus was measured. The result showed that the bacterial isolates has different ability in inhibiting the growth of S. rolfsii. Enterobacter sp. BK15 and Bacillus sp. BK13 were the most effective in inhibiting the growth of S. rolfsii with inhibition zone of 3.70 cm and 3.75 cm, respectively. The less effective was shown by Enterobacter sp. PB17 with inhibition zone of 0.10 cm, while Enterobacter cloacae LK08 have no ability to inhibit S. rolfsii. The seeds soaked in bacterial suspension by Bacillus sp. BK13 dan Enterobacter sp. BK15 were able to reduce damping off by 44.4% and 50%, respectively

Pemanfaatan E-Government Di Masa Pendemi Dalam Meningkatkan Pelayanan Publik

Pengabdian Kepada Masyakat ini berjudul Peningkatan Pelayanan Publik Di Masa Pendemi   Melalui E-Goverment. Pengabdian ini dilakukan di Desa Talang Kemuning Kecamatan Bukit Kerman Kabubaten Kerinci, Propinsi Jambi. Saat ini, dimana situasi pendemi-Covid 19 ini, pelayanan publik menjadi tantangan terpenting bagi pemerintahan. Pelayanan publik harus tetap berjalan dengan baik dan optimal. E-goverment adalah salah satu konsep layanan yang menggunakan teknologi informasi. Dengan menerapkan kebijakkan tersebut dapat mempercepat dan mempermudah memberikan pelayanan. Namun pada kenyataannya terdapat kendala dalam menerapkan e-goverment, yaitu masih terbatas aparatur desa yang memiliki pengetahuan di bidang teknologi informasi. Selain itu, keterbatasan pengetahuan karena kurang mendapatkan pelatihan serta data-data yang ada tidak tersinkron dengan baik bahkan tidak menggambarkan keadaan sebenarnya.  Untuk itu diperlukan suatu penyuluhan dan pelatihan mengenai sistem e-goverment untuk meningkatkan pelayanan publik

Food deprivation explains effects of mouthbrooding on ovaries and steroid hormones, but not brain neuropeptide and receptor mRNAs, in an African cichlid fish

Feeding behavior and reproduction are coordinately regulated by the brain via neurotransmitters, circulating hormones, and neuropeptides. Reduced feeding allows animals to engage in other behaviors important for fitness, including mating and parental care. Some fishes cease feeding for weeks at a time in order to provide care to their young by brooding them inside the male or female parent\u27s mouth. Maternal mouthbrooding is known to impact circulating hormones and subsequent reproductive cycles, but neither the full effects of food deprivation nor the neural mechanisms are known. Here we ask what effects mouthbrooding has on several physiological processes including gonad and body mass, brain neuropeptide and receptor gene expression, and circulating steroid hormones in a mouthbrooding cichlid species, Astatotilapia burtoni. We ask whether any observed changes can be explained by food deprivation, and show that during mouthbrooding, ovary size and circulating levels of androgens and estrogens match those seen during food deprivation. Levels of gonadotropin-releasing hormone 1 (GnRH1) mRNA in the brain were low in food-deprived females compared to controls and in mouthbrooding females compared to gravid females. Levels of mRNA encoding two peptides involved in regulating feeding, hypocretin and cholecystokinin, were increased in the brains of food-deprived females. Brain mRNA levels of two receptors, GnRH receptor 2 and NPY receptor Y8c, were elevated in mouthbrooding females compared to the fed condition, but NPY receptor Y8b mRNA was differently regulated by mouthbrooding. These results suggest that many, but not all, of the characteristic physiological changes that occur during mouthbrooding are consequences of food deprivation. © 2012 Elsevier Inc

Large Scale Nanoparticle Screening for Small Molecule Analysis in Laser Desorption Ionization Mass Spectrometry

Nanoparticles (NPs) have been suggested as efficient matrixes for small molecule profiling and imaging by laser-desorption ionization mass spectrometry (LDI-MS), but so far there has been no systematic study comparing different NPs in the analysis of various classes of small molecules. Here, we present a large scale screening of 13 NPs for the analysis of two dozen small metabolite molecules. Many NPs showed much higher LDI efficiency than organic matrixes in positive mode and some NPs showed comparable efficiencies for selected analytes in negative mode. Our results suggest that a thermally driven desorption process is a key factor for metal oxide NPs, but chemical interactions are also very important, especially for other NPs. The screening results provide a useful guideline for the selection of NPs in the LDI-MS analysis of small molecules
