Eindrapport KenSys - Kennismanagement in de praktijk: Resultaten van de implementatie van een Kennis Systeem bij de Directie Zuid-Holland 1998-2003
No full textAANLEIDING In september 1998 is bij RWS directie Zuid Holland, hoofdgroep planvorming (AP) het KenSys project gestart. Aanleiding voor het starten van het KenSys project was de wens om de kwaliteitsborging van het werk van AP een flinke stimulans te geven. Nieuwe medewerkers hadden vaak geen goede, gemakkelijke toegang tot oudere documenten. Ze waren slecht op de hoogte van beschikbare kennis en ervaring bij de eigen dienst en bij de specialistische diensten. Hierdoor werd bestaande kennis niet goed benut. Het KenSys project bij AP had als doel om met kennismanagement de kwaliteit van het werk te borgen en het gebruik van bestaande kennis te vergroten. AANPAK Het KenSys project is in 5 fasen uitgevoerd: 1. September 1998-September 1999: de verkenningsfase. Creëren van draagvlak op de werkvloer voor kennis borging en kennis delen. Er is onderscheid gemaakt tussen een technologisch en een organisatorisch spoor. Zie ook [Demis rapport, 4-1999]. 2. September 1999-Juli 2000: de ontwerp/pilot fase. Er zijn een digitale boekenkast en smoelenboek geïntroduceerd. Ook is een nulmeting verricht. Zie ook [Demis memo, 5-2000] 3. Augustus 2000-December 2001: de implementatie fase. Implementatie zoekmachine (KennisBrowser) Uitwerking nulmeting. Zie ook [Demis verslag, 7-2001] en [Demis nota, 8-2001]. 4. Januari 2002-Januari 2003: de \u93Inbedden en Oogsten\u94 fase. Oplevering van de KennisBrowser en de ICT-componenten van het KenSys systeem met documentatie. 5. Januari 2003-Juli 2004: de eindafhandeling. Schriftelijke en mondelinge presentaties van de resultaten. Een samenvatting en rapportage van fasen 1 en 2 en een beschrijving van fase 3 is gegeven in [RIKZ rapport, 11-2000]. Dit rapport wordt kort besproken in hoofdstukken 2 , 3 en 4. Een nuttige samenvatting van het gehele project wordt gegeven in [Demis rapport, 2-2003]. RESULTATEN: Na het verkrijgen van draagvlak van medewerkers op de werkvloer in 1998/1999 zijn in een workshop in juni 1999 een negental concrete (goedkope) acties voor organisatorische verbeteringen evenals vier acties voor snelle technologische verbeteringen uitgekozen. Van de organisatorische verbeteringen zijn gelukt: 1. Kwaliteitscontrole rapporten 2. Up-to-date producten overzicht 3. Fysieke tentoonstelling producten APS 4. Digitale smoelenboek en daardoor betere uitwisseling van persoonlijke ervaringen. Niet goed gelukt zijn: 5. Betere benutting bestaande systemen (Geokey, DONAR, Oaseview, OMEGA) 6. Overzicht vragen en benodigde informatie (projectendatabase) 7. Interne kennisoverdracht door lezingen en koffiepraatjes 8. Versterken informele kontakten APS/APV en met klanten en/of kennisleveranciers. 9. Digitale opslag en terugzoeken luchtfoto\u92s. Van de 4 technologische acties (t.b.v. het project \u93Ander Beheer Haringvliet\u94) zijn er twee wel geslaagd: 1. Borgen kennis door opslaan alle relevante documenten in de vorm van een projectsite. 2. Distribureren van kennis (via Website) voor allerlei interne en externe betrokkenen. De andere twee acties: 3. Monitoren status 4. voortgang werkproces en bijdragen aan discussies tussen betrokken partijen zijn niet van de grond gekomen. Dit vanwege onvoldoende draagvlak (wat betreft de monitoring) en onvoldoende technische ondersteuning (wat betreft het distribueren van kennis via een website). Het doel van de fases 3 en 4 was om een kennisportaal te maken met een geïntegreerd smoelenboek, een projectendatabase, een geavanceerde zoekmachine (KennisBrowser) en een digitale boekenkast. Dit heeft de nodige moeite gekost (met name de zoekmachine) maar is toch gelukt. Het systeem draait nu goed bij AP en AV. CONCLUSIES \u95 Er is bij AP een attitude verandering ontstaan. Hierdoor zien medewerkers het nut van kennis delen en borgen in. Het succes van de huidige DZHintranet site is onder meer te verklaren door deze attitude-verandering. \u95 De kennis bij de afdelingen AP en AV is veel toegankelijker geworden door gebruik van het uitgebreide smoelenboek en het (elektronisch) gemakkelijk vinden van grijze en officiële stukken. \u95 De KennisBrowser is een hoogwaardige zoekmachine die snel en eenvoudig associaties binnen documenten zichtbaar kan maken. Het indexeren blijft een aandachtspunt. De KennisBrowser is een PC-applicatie, wat in de toekomst misschien kan botsen met de huidige Web-based gedachten. \u95 Er is bij de afdelingen AP en AV ervaring opgedaan met diverse ICT-tools voor Kennismanagement portalen, te weten: de officiële boekenkast AP, de open boekenkasten AP en AV, de smoelenboeken AP en AVS en de RWS KennisBrowser. Deze ervaringen zijn waardevol geweest. \u95 Een t=1 meting zou (door vergelijking met de wel uitgevoerde t=0 meting) moeten uitwijzen in hoeverre de beschikbare tools worden gebruikt en tot hogere efficiency hebben geleid.KenSy
The Reign
No full textThe Reign is a novel set in a fictional world where, after a cosmic event, those living on the continent of Fieldry’s genetics are altered, creating three new sub-species: the Demis, Anir, and Sentil. Some believe those who are Reign Touched were blessed by the Gods, whereas others cannot forget or forgive the violent afflictions caused by the Demis during the events of the Reign. The story follows our main protagonist Ashryn and a cast of characters who find themselves confronted with two mysteries; the Keeper, a monstrous man, whose true identity remains unknown, and his mission to rid Fieldry of its Demi population by any means, and the sudden disappearance of one of Ashryn’s closest childhood friends. The novel deals with themes of friendship, oppression, love, found family, acceptance, and the will to fight against an unjust world.

Psychology Of Language Acquisition In Young Children And Implications For Language Education Policy Making
No full textAbove and beyond political implications, proper language policy planning and implementation assume a paramount role in educational practices as well. Addressing language issues to a required level of satisfaction is, therefore, a critical factor for educational quality. The objective of this paper is, then, to explore the psychological dimensions of language acquisition and learning among young children in Ethiopia and draw implications for proper language policy making. It attempts to examine psychological processes, determinants, and implications of language acquisition, and L2, L3 learning. Pursuant on this goal, existing psychological theories of language development were critically reviewed at the beginning. This theoretical review was followed by consultations of international and African experiences to learn from practices. Furthermore, Ethiopian experiences were also brought to the fore and reflected up on based on theoretical and practical experiences. Then, implications were drawn for better language planning and implementation in the country
Pooled prevalence and predictors of intraventricular hemorrhage (IVH) in preterm neonates (28–34 weeks) in Africa: a systematic review and meta-analysis
No full textAbstract Objective To assess the pooled prevalence and predictors of intraventricular hemorrhage (IVH) among preterm neonates born between 28 and 34 weeks of gestational age in Africa. Method A weighted inverse-variance random-effects model estimated the pooled prevalence and predictors of germinal matrix hemorrhage. Heterogeneity was assessed using forest plots and I² statistics, focusing on studies conducted in African settings. Cross-sectional studies published in English between 2004 and 2022 were identified through online and manual searches conducted from September 18 to October 27, 2024. Outcome measure Intraventricular hemorrhage/Germinal matrix hemorrhage (Grades I-IV), defined as bleeding in a developing brain region that typically resolves by term gestational age. Result Ten primary studies involving 2,622 preterm neonates born at 28–34 weeks of gestation were included. The pooled prevalence of IVH was nearly three in ten cases, with substantial heterogeneity across studies (I² = 99%, P < 0.001). Extremely premature neonates had almost twice the risk of IVH compared to those born after 28 weeks (AOR = 1.98; 95% CI: 1.31–3.64). Antenatal corticosteroid (ANC) administration reduced IVH risk by 35% (AOR = 0.65; 95% CI: 0.08–0.78), while intubation status showed no significant effect (AOR = 1.04; 95% CI: -0.19–2.28). Conclusion The pooled prevalence of IVH in very preterm and very low birth weight (VLBW) neonates in Africa was considerable, affecting nearly three out of ten cases. Extremely premature neonates were almost twice as likely to develop IVH compared to those born after 28 weeks of gestation, while antenatal corticosteroid (ANC) administration significantly reduced the risk. Intubation status had no significant impact on IVH risk. These findings highlight the urgent need for healthcare professionals and policymakers to prioritize preterm care standards in Africa to improve neonatal outcomes. PROSPERO ID CRD42024499505
Uptake of Cervical Cancer Screening and Its Barriers Using Health Belief Model Among Health Professionals Working in Public Hospitals in South Gondar Zone, Northcentral Ethiopia: Multicenter Cross-Sectional Study
No full textBackground: Cervical cancer is a malignant neoplasm that originates in the cervix, and it is a leading cause of mortality, with 270,000 deaths every year globally. Of these, 85% occur in developing countries, including Ethiopia. Routine cervical cancer screening and early treatment can prevent up to 80% of cervical cancers. Health professionals are expected to screen for and be screened for cervical cancer. However, there is limited information about the uptake of cervical cancer screening among health professionals in the study area.
Objective: This study aimed to determine the magnitude of cervical cancer screening uptake and identify its barriers among health professionals.
Methods: A multicenter cross-sectional study design was conducted among health professionals from December 01 to 30, 2022. A total of 164 respondents were included in the study, and simple random sampling was used to select the respondents. Variables with a p-value of <0.05 at 95% confidence interval (CI) were considered significantly associated with the outcome variable.
Results: Of the total respondents, 112 (68.3%) were younger than the age of 30 years, with a mean age of 29.4 years ranging from 21 to 45 years. Seventy-nine of the respondents (48.2%) have work experience of 6?10 years, and 103 (62.8%) are nurses in profession. In this study, the magnitude of cervical cancer screening uptake was 28.1% (95% CI: 27.7%?35.6%). Moreover, attitude (adjusted odds ratio [AOR]?=?3.3, 95% CI: 2.1?5.1), age at first sexual intercourse (AOR?=?2.1, 95% CI: 1.3?3.4), having history of sexually transmitted infections (STIs; AOR?=?3.6, 95% CI: 1.5?11.6), knowing someone who had been screened (AOR?=?2.9, 95% CI: 1.8?4.8), and cervical cancer screening training (AOR?=?1.6, 95% CI: 1.1?2.9) were significantly associated with cervical cancer screening.
Conclusion: Generally, this study reported that the magnitude of cervical cancer screening uptake was low. The study also indicated that attitude, age at first sexual intercourse, history of STIs, knowing someone who had been screened, and training of cervical cancer screening were independent predictors of uptake of cervical cancer screening
Prevalence and contributing factors of early initiation of breastfeeding (EIBF) in Ethiopia: a systematic review and meta-analysis
No full textAbstract Background Even though the National Infant and Young Child (IYC) Feeding guideline was launched in Ethiopia in 2016, early initiation of breastfeeding is not consistently measured among studies which limit evidence for the development of promotion strategies. Methods A weighted inverse-variance random effects model was used to estimate the pooled prevalence and contributing factors of early initiation of breastfeeding (EIBF). Heterogeneity was assessed using the I² statistic, forest plot, and Egger’s test. Data from 22 primary studies across all regional states in Ethiopia were analyzed, including 39,316 mother-infant pairs who had given birth and breastfed within the last two years, from December 11, 2023, to January 16, 2024. Results The pooled prevalence of EIBF was 67.44% (95% CI: 61.31–73.56, I² = 99.40%, P = 0.001). Factors contributing to EIBF included urban residency (OR = 2.7, 95% CI: 2.11–3.30), regular antenatal care (OR = 2.44, 95% CI: 1.72–3.15), absence of prelacteal feeding (OR = 4.26, 95% CI: 2.93–5.60), secondary or higher education (OR = 2.53, 95% CI: 1.39–3.68), highest maternal wealth index (OR = 2.36, 95% CI: 1.62–3.09), health facility delivery (OR = 3.60, 95% CI: 2.58–4.62), receiving health education during antenatal care (OR = 1.62, 95% CI: 1.40–1.84), and breastfeeding support (OR = 3.56, 95% CI: 2.38–4.73). Conclusion The prevalence of early breastfeeding initiation (EIBF) remains below WHO targets. Factors like urban residence, higher education, and access to antenatal care and hospital-based delivery services are positively linked to EIBF. To improve rates, health services should enhance community outreach, promote antenatal care, provide early breastfeeding education, and offer professional support immediately after birth.

Genetic evaluation of growth rate and efficiency-related traits in Menz sheep
No full textGrowth efficiency traits are economically important and their genetic improvement is essential in small ruminants, particularly under conditions of limited feed availability. Data on body weights of Menz sheep collected from 2009 through 2023 in Menz sheep community-based breeding programs (CBBPs) were used to estimate genetic parameters for six months weight (WT6), average daily gain from birth to weaning (ADG1), average daily gain from weaning to six months (ADG2), and average daily gain from six months to yearling (ADG3), and corresponding kleiber ratios (KR1, KR2, KR3), efficiency of growth (GE1, GE2, GE3), and relative growth rate (RGR1, RGR2, RGR3). Least-squares analysis was performed using the PROC GLM procedure in SAS 9.4. (Co)variance components and corresponding genetic parameters were estimated using the Average Information Restricted Maximum Likelihood (AI-REML) method in WOMBAT software by fitting six univariate animal models that incorporated various combination of direct additive, maternal genetic, and permanent environmental effects. The year of birth, season and villages of CBBP contributed significantly (P < 0.001) to the variation of all the considered traits. The model with direct additive genetic effect alone provided the best fit for all traits except WT6 and ADG1, for which the model including direct and maternal genetic effects performed best. Direct heritability estimates (h2a) were 0.46 ± 0.02, 0.44 ± 0.02, 0.35 ± 0.02, 0.21 ± 0.02, 0.38 ± 0.02, 0.36 ± 0.02, 0.23 ± 0.02, 0.39 ± 0.02, 0.39 ± 0.02, 0.48 ± 0.03, 0.36 ± 0.02, 0.42 ± 0.02, and 0.47 ± 0.03 for WT6, ADG1, ADG2, ADG3, KR1, KR2, KR3, GE1, GE2, GE3, RGR1, RGR2, and RGR3, respectively. Maternal heritability (h2m) for WT6 and ADG1 was 0.02 ± 0.01 and 0.02 ± 0.01. Moderate to high direct heritability estimates for the studied traits revealed that direct selection would be yield significant genetic progress. Genetic correlation estimates between the traits raged from -0.66 for ADG1-RGR2 and KR1-RGR2 to 0.98 for KR2-RGR2. Traits measured within the same growth period showed strong positive genetic and phenotypic correlations. Since Menz sheep are raised under harsh environmental conditions, incorporating efficiency related traits into the selection program can enhance the overall efficiency of the breeding program. Selection for WT6 would be more effective and increase efficiency-related traits due to their positive genetic correlations
Estimates of genetic parameters and genetic trends for growth traits in Menz sheep under community-based breeding programs
No full textThe main objectives of this study were to estimate genetic and phenotypic parameters for growth traits in Menz sheep under community-based breeding programs (CBBPs). Data used in the study were collected from five Menz CBBPs villages during 15-year period (2009–2023). Studied growth traits were birth weight (BW), weaning weight (WW), six-month weight (6 MW), yearling weight (YW), Average daily gain from birth to weaning (ADG1), average daily gain from weaning to six months (ADG2) and average daily gain from six months to yearling (ADG3). Fixed effects were estimated using the GLM procedure of SAS 9.4. Genetic parameters were estimated fitting different univariate animal models using Average Information Restricted Maximum Likelihood (AI-REML) procedure with WOMBAT software. The most appropriate model for each trait was determined applying likelihood ratio tests. Model including only direct additive genetic effect was the most appropriate model for BW, YW, ADG2 and ADG3, whereas model including direct additive and maternal additive genetic effect without taking into account covariance between them was the most appropriate for WW, 6 MW and ADG1. Based on the most appropriate models, direct heritability of BW, WW, 6 MW, YW, ADG1, ADG2 and ADG3 were 0.29 ± 0.01, 0.45 ± 0.01, 0.46 ± 0.02, 0.42 ± 0.02, 0.44 ± 0.01, 0.75 ± 0.02 and 0.21 ± 0.02, respectively. The estimated maternal heritability were 0.04 ± 0.01, 0.02 ± 0.01 and 0.02 ± 0.01 for WW, 6 MW and ADG1, respectively. Additive coefficient of variance were ranged from 9.53 % for BW to 33.02 % for ADG2. Moderate to higher estimates of direct heritability and additive coefficient of variation (CVA) in the current study indicates higher potential for genetic improvement of studied traits through direct selection. The genetic trend for the Menz sheep's six-month weight in Molale CBBPs village reveals a promising annual growth rate of 0.20 kg. Optimizing the ongoing breeding program into specializing-sire producer groups and applying intensive selection on the sub-nucleus flock could improve the efficiency of the breeding program. Genetic correlations among the studied traits were ranged from −0.50 for ADG-ADG2 to 0.98 for WW-ADG1. Genetic correlation between 6 MW and other studied traits was positive and moderate in magnitude. To achieve optimum genetic gain, the implemented selection criteria for Menz sheep (6 MW) should be continued
