This study argues that preservation of internal security of Namibia should not be the primary responsibility of only the Namibian Police Force (NamPol). The issue of security has been the subject of interest throughout human existence and still reserves its principal occupation in the public domain. However, the challenges of insecurities and increased threats to human existence domestically and globally have triggered incessantly renewed security inquiry by scholars, security practitioners, politicians and public administrators. The study employed a qualitative approach; interviews were used to purposively collect data from 20 participants which comprised of the heads of directorates, the regional commanders in the Namibian Police Force, Legal Assistance Centre, NamRights, Namibian Defence Force, Namibian Correctional Service and Windhoek Municipal Police. The data was analysed using thematic analysis, which led to the development of the Framework for Performing Internal Security [FPIS] model. The findings indicate that due to the nature of factors linked to insecurities, such as technology, porous borders, political factors, environmental factors, inequality, poverty, unemployment and lack of provision for essential services, the Namibian police alone cannot preserve internal security effectively. As such, the study recommends that constitutional amendments to incorporate other stakeholders in the preservation Namibia's internal security.

The purpose of this paper is to begin a dialogue of developing a integrated and comprehensive system for youth in Kenya by identifying factors impacting the creation of a youth development system and exploring recommendations supporting and advancing such a system. The results of two collaborative assessments of the needs and strengths of Kenyan youth and the youth-serving programs based on the perspectives of practitioners, policy-makers, and scholars of youth-development are presented. The study was framed from the perspective of a systems approach to youth development in Kenya (Bronfenbrenner & Morris, 2006; Overton & Lerner, 2012). Osgood (2012) identifies four steps for developing a systems approach for serving the needs of youth: (1) self-assessment, (2) goal identification, (3) planning, and (4) networking. The first step, self-assessment, was initiated through a SWOT analysis with two different groups of youth development professionals across a 2-year period (2014-2015). The 2014 SWOT analysis presented the strengths, weaknesses, opportunities, and threats related to developing a youth development system from a national level, whereas the 2015 SWOT analysis focused on these same factors but from a more local level of youth development programs and services. The results of these two analyses are presented and initial recommendations for building a more integrated and comprehensive youth development system in Kenya are presented. The need for further input and investigation is also discussed. This is a correction to the original article.

Abstract

Objectives
Since the 1920s, Zambia's mining sector has experienced growth, which has increased the number of mine workers employed in the industry. Consequently, the potential for occupational exposure and prevalence of occupational diseases have also increased. Unfortunately, Zambia does not currently have legislative guidelines for workplace air monitoring and compliance. This study's objectives were to evaluate copper miners' personal exposure to respirable dust and respirable crystalline silica (RCS) and to assess workplace compliance using the European Standard for workplace air monitoring and measurement (EN689:2018).


Methods
This cross-sectional study collected 100 personal respirable dust exposure samples at a Zambian copper mine in 2023. These samples were weighed using NIOSH method 0600 and analyzed for crystalline silica using Fourier transform infrared spectroscopy (KBr pellet) (NIOSH method 7602). Additionally, 253 respirable dust exposure measurements collected at the mine between 2017 and 2022 were included for comparison.


Results
The median respirable dust exposure for the 2023 exposure measurements was 0.200 mg/m3 (95th percentile 2.871 mg/m3) compared to 0.400 mg/m3 (95th percentile 3.050 mg/m3) for the historic data. The median RCS exposure was 0.012 mg/m3 (95th percentile 0.163 mg/m3). Using EN689:2018, it was found that from 15 work areas, only six work areas complied with the standard for respirable dust exposure and only seven work areas complied with the standard for RCS exposure.


Conclusions
At the mining site, several work areas had substantial exposure to respirable dust and RCS. Therefore, management needs to prioritize these areas when implementing control measures to reduce dust exposure. For the Zambia mining industry to manage exposure to respirable dust and RCS, it is necessary to implement standardized monitoring strategies. This study has demonstrated that EN689:2018 can be used successfully to determine compliance among Zambian mining work areas.
