The Influence of Organisational Culture on Knowledge Sharing in Selected Municipalities in Limpopo, South Africa
Authors: Dikotla Maoka Andries , Ledwaba Lethabo
Published: May 2023

Organisational culture is an important factor and has a strong influence on knowledge sharing within institutions. The prevailing culture can either support or compromise knowledge sharing in municipalities. The aim of this study was to investigate the influence of organisational culture on knowledge sharing in some municipalities in Limpopo, South Africa. This study used both quantitative and qualitative research methods. Thus, data was collected using both structured questionnaires and interviews. Quantitative data was analysed using IBM Statistical Package for Social Science (SPSS) 23 software, while qualitative data was analysed using a thematic analysis method. The study revealed that the existing culture in Limpopo municipalities is not conducive to sharing organisational knowledge due to a culture of knowledge hoarding, mistrust, fear and political influence. A policy needs to be developed to protect employees from political influence. To create a conducive environment, where employees can trust each other and knowledge sharing can thrive, managers can encourage staff members to share best practices with their colleagues and consult with them when faced with problems or challenges, rather than taking the challenge to a manager. Municipalities should also build formal recognition and reward systems to compensate employees demonstrating knowledge-sharing behaviours. A comparative study on knowledge sharing in both municipalities and government departments in Limpopo as a whole is recommended.
Records and Information Management (RIM) Practices in Pentecostal Churches in Zimbabwe
Authors: Chitima Simbarashe Shadreck , Ndlovu Heather , Phiri Calvin
Published: May 2023

Zimbabwe has, for the past five decades, experienced a proliferation of Pentecostal churches. Some Pentecostal churches or prophets own television channels and social media accounts, which they have used for communication and preaching. In some instances, Pentecostal churches run several projects and church activities. All these activities and operations have resulted in the creation of financial, personal, prophecy and project records, among others. Although Pentecostal churches are not archives or records centres, they stand to benefit if they engage in Records Information Management (RIM). The Apostolic Faith Mission in Zimbabwe (AFMZ) and the United International Apostolic Faith Church (UIAFC) both experienced splits in 2018, and this has contributed to information loss and the destruction of vital records. This study investigated the efficacy of RIM practices in the AFMZ and UIAFC and was grounded on qualitative and phenomenological research methods. The target population included pastors, secretaries and treasurers from the AFMZ and UIAFC who are part of the RIM chain. The study found that the lack of a RIM policy, trained personnel and physical as well as technological infrastructure contributed to records and information loss. Pentecostal churches are susceptible to splits. Records or information is usually managed by lay workers (volunteers) with less knowledge of RIM; hence this has attributed to information loss and records destruction. It is thus concluded that RIM in Pentecostal churches remains an afterthought. This study established critical RIM factors that Pentecostal churches may find useful, and which can increase their efficiency and effectiveness in operations and business.
Freedom Charter, Women's Charter, Memories, and (Un)freedoms
Authors: Archary Kogielam Keerthi
Published: May 2023

More than 60 years ago, South African women declared their aim of striving for the removal of all laws, regulations, conventions and customs that discriminated against women and that deprived them in any way of their inherent right to the advantages, responsibilities and opportunities that society offered to any one section of the population. Women do not form a society separate from men. There is only one society, and it is made up of both women and men. Against this backdrop, after 60 years, and with a Women’s Charter and Freedom Charter in place, there are many issues that still need to be addressed, highlighted and referred to. On the agenda is the investigation of unresolved women’s issues so as to pave the way for emancipation from the (un)freedoms that still prevail. On August 9, 1956, more than 20 000 women marched to the Union Buildings in Pretoria to protest against the extension of women’s pass laws. This march, organised by the Federation of South African Women, has been recorded as one of the largest demonstrations staged in this country’s history. Women have played an important role in building a better South Africa. They should be protected against abuse, violence and discrimination, and they must be valued and respected in order to uphold the vision of building a non-racist, non-sexist and prosperous South Africa. Against this background, celebrating the 60th anniversary of the Women’s Charter and 25 years of freedom indicates that change should have taken place over the last six decades. However, the liberation, education and management of South African women within the paradigm of political, legal, economic and social challenges need to be investigated and documented.

Objectives:

The objective of this study is to provide an overview of the psychological autopsy (PA) research method, including its methodology, uses, limitations, and ethical considerations.

Materials and Methods:

The study conducted a PA investigation on 35 cases of suicide. Information was collected from multiple sources and reliable informants, including family members, friends, medical and mental health professionals, and other relevant individuals. Qualitative and quantitative research methods were used to analyze the collected information.

Results:

The results indicated that several factors were associated with suicide, including mental health problems, life stressors, interpersonal conflicts, substance abuse, and history of previous suicide attempts. The findings have important implications for suicide prevention strategies, emphasizing the significance of addressing mental health issues and providing social support.

Conclusion:

The PA is a valuable research method for investigating and understanding suicide. Despite challenges such as recall biases and methodological limitations, it provides insights into the psychological factors associated with suicide and informs suicide prevention strategies. However, conducting psychological autopsies requires careful consideration of ethical issues. Further research is needed to replicate and extend the findings of this study

Published: May 2023

We demonstrate the utility of block polyelectrolyte (bPE) additives to enhance viscosity and resolve longstanding challenges with the three-dimensional printability of extrusion-based biopolymer inks. The addition of oppositely charged bPEs into solutions of photocurable gelatin methacryloyl (GelMA) results in complexation-driven self- assembly of the bPEs, leading to GelMA/bPE inks that are printable at physiological temperatures, representing stark improvements over GelMA inks that suffer from low viscosity at 37 °C leading to low printability and poor structural stability. The hierarchical microstructure of the self-assemblies (either jammed micelles or three-dimensional networks) formed by the oppositely charged bPEs, as confirmed by small angle X-ray scattering, is attributed to the enhancements in the shear strength and printability of the GelMA/bPE inks. Varying bPE concentration in the inks is shown to enable tunability of the rheological properties to meet the criteria of pre- and post-extrusion flow characteristics for 3D bioprinting, including prominent yield stress behavior, strong shear thinning, and rapid recovery upon flow cessation. Moreover, the bPE self-assemblies also contribute to the robustness of the photocrosslinked hydrogels – photocrosslinked GelMA/bPE hydrogels are shown to exhibit higher shear strength than photocrosslinked GelMA hydrogels. We envision this study to serve as a practical guide for the bioprinting of bespoke extrusion inks where bPE are used as scaffolds and viscosity enhancers that can be emulated in a range of biopolymers and photocurable precursors.
3D Based Generative PROTAC Linker Design with Reinforcement Learning
Authors: li baiqing , Chen Hongming
Published: May 2023

Proteolysis targeting chimeras (PROTACs), have emerged as an effective therapeutic modality by harnessing the ubiquitin-proteasome system to selectively induce targeted protein degradation, with the potential to modulate traditional undruggable targets. Due to its hetero-bifunctional characteristics, in which a linker joins warhead binding to a protein of interest, conferring specificity, and E3-ligand binding to an E3 ubiquitin ligase, a PROTAC molecule can form a PROTAC ternary structure for bring the protein of interest to the vicinity of the E3 ligase. The rational PROTAC linker design is challenging due to its relatively large molecular weight and the complexity of maintaining the binding mode of warhead and E3-ligand in the binding pockets of counterpart. Conventional linker generation method can only generate linkers in either 1D SMILES or 2D graph, without taking into account the information of ternary structures. Here we propose a novel 3D linker generative model PROTAC-INVENT which can not only generate SMILES of PROTAC but also its 3D putative binding conformation coupled with the target protein and the E3 ligase. The model is trained jointly with the RL approach to bias the generation of PROTAC structures toward pre-defined 2D and 3D based properties. Examples were provided to demonstrate the utility of the model for generating reasonable 3D conformation of PROTACs. On the other hand, our results show that the associated workflow for 3D PROTAC conformation generation can also be used as an efficient docking protocol for PROTACs.
The effect of methyl group rotation on 1H-1H solid-state NMR spin-diffusion spectra

Published: May 2023

Fast magic-angle spinning (MAS) NMR experiments open the way for proton-detected NMR studies and have been explored in the past years for a broad range of materials, comprising biomolecules and pharmaceuticals. Proton-spin diffusion (SD) is a versatile polarization-transfer mechanism and plays an important role in resonance assignment and structure determination. Recently, the occurrence of negative cross peaks in 2D 1H-1H SD-based spectra has been reported associated with higher-order SD effects, in which the chemical shifts of the involved quadruple of nuclei need to compensate each other. We herein report negative cross peaks in SD-based spectra observed for a variety of small organic molecules involving methyl groups. We combine experimental observations with numerical and analytical simulations to demonstrate that the methyl groups can give rise to coherent (SD) as well as incoherent (Nuclear Overhauser Enhancement, NOE) effects, both in principle manifesting themselves as negative cross peaks in the 2D spectra. The simulations however reveal that higher order coherent contributions dominate the experimentally observed negative peaks. Methyl groups are prone to the observation of such higher order coherent effects. Due to their low-frequency shifted 1H resonances, the chemical-shift separation relative to for instance aromatic protons in spatial proximity is substantial (> 4.7 ppm in the studied examples) preventing any sizeable second-order spin-diffusion processes, which would superimpose the negative contribution to the peaks.
Characteristic nuclear spin-induced optical rotation in oxygen-containing organic molecules
Authors: Kamula Eelis , Vaara Juha , Štěpánek Petr
Published: May 2023

Nuclear spin-induced optical rotation (NSOR) is a nuclear magneto-optic effect that manifests itself as a rotation of the plane of polarization of linearly polarized light. The effect is induced by ordered nuclear magnetic moments within a molecule. NSOR is sensitive to specific, localized interactions. Hence, the connection between the local chemical environment and the corresponding NSOR signal is crucial to understand. Despite the fact that contributions to better understand the connection have been made, the general systematics still remain unknown. In this paper, NSOR in oxygen compounds is investigated systematically to better understand the impact of oxygen atoms on the NSOR signal. NSOR signals are computed using density-functional theory methods for five different classes of oxygen compounds. The ability of NSOR to distinguish different molecules and individual nuclei in the molecules is studied and the information provided by NSOR is compared to conventional NMR spectroscopy. The results reveal that NSOR is capable of chemical distinction between nuclei and molecules, and by using NMR and NSOR together it is possible to distinguish nuclei near the oxygen atom.

Published: May 2023

GCPII also known as Prostate Specific Membrane Antigen (PSMA), is overexpressed in prostate cancer (PCa) cells and provide a biomarker for tumor targeting PSMA receptor. The development of lysine-urea-glutamate pharmacophore based inhibitors targeting PSMA for theranostics applications led to PSMA11 and PSMA617. In PSMA11, this pharmacophore is attached via aminohexanoic acid (Ahx) spacer to a chelator while in PSMA617 the pharmacophore is connecting with the linker 2-naphthyl-L-Ala, trans-4-(aminomethyl)cyclohexanecarboxylic acid and then to chelator. Here, we synthesized: (a) a squaramide analog of lysine-urea-glutamic acid; (b) two new building blocks for PSMA theranostics in which lysine-urea-glutamic acid was attached with two (i) phenyl alanine residues and (ii) amino hexanoic acid residues. Induced fit docking explored the binding profile of the new molecules. Biological experiments will provide data on the significance of the new molecules.

Published: May 2023

This research analyze the effect of the Application of CPTED and study improvement measures for the Prevention of Military Crime through various studies and CPTED application cases, military crime trends and crime trends. In particular, it was confirmed that the CPTED has a positive effect on military crime reduction, security and safety awareness through the first CPTED application case in the military. Therefore, this study suggested improvement measures to apply CPTED to the prevention of military crimes. First, it is the development of a CPTED-applied introduction model suitable for the military. In this study, a crime prevention activity model was presented in the order of pre-measures based on the CPTED principle, CPTED implementation, and follow-up management. Second, it is necessary to train CPTED experts (MCPO). Currently, the military lacks CPTED professionals necessary for CPTED application. In the future, it is essential to train experts for the operation of the Military Crime Prevention Officer (MCPO) of the military police. Third, it is necessary to form a CPTED consensus and activate a crime prevention consultative group. In order to successfully apply CPTED to the military, above all, responsibilities between crime prevention agents must be clearly defined and the consultative group must be reorganized and activated while forming a consensus on the application of CPTED among each agents. In this case, collaboration with specialized institutions inside and outside the military should also be carried out. Fourth, institutionalization for the application of CPTED to the military is necessary. In order to apply CPTED more systematically, it is important to expand the agents of crime prevention activities and clarify its responsibilities. To this end, the military also needs to establish a legal and institutional foundation and CPTED should be institutionalized by reflecting the concept of CPTED in military regulations and guidelines.

Authors:   KOREA CPTED ASSOCIATION, Hong Myeonggi , Jang Hyun-Seok
Published: May 2023

Based on the discussion of environmental criminology, this study aims to identify the distance criminals journey to commit crimes. Verifying how much a criminal moves to commit a crime has the advantage of predicting the distance and helping the police investigation. According to the results of the study, sex crimes showed the highest density within 2km of the criminal's residence, and after that, they gradually decreased. As a result of OLS regression analysis, it was confirmed that the distance of movement of a crime varies not only according to the characteristics of the criminal but also according to modus operandi such as the relationship between the criminal and the victim, whether the body is inserted, and whether coercive means are used. In addition, as a result of the potential class analysis of criminal methods, there was a difference in the distance of movement of sex crimes according to the potential (group) type of sex crimes. Finally, by synthesizing the results, the development direction of geographic profiling required for evidence-based policing and limitations were discussed due to the problem of analysis data.
A Study on the Factors Influencing the Safety of Indoor Space in Adjacent Kindergartens through Teacher Survey - Focusing on living safety and criminal safety -
Authors:   KOREA CPTED ASSOCIATION, Yang Heewon , Lee Yumi , Sung Yuhyun
Published: May 2023

Due to the recent increasing demand for public education, the number of kindergartens attached to elementary schools, which are public kindergartens, is steadily increasing. However, in the case of kindergartens attached to elementary schools, living safety and criminal safety are concerned in the space used by elementary school students and infants together. Therefore, this study conducted a questionnaire survey on safety awareness and improvement measures for the components of each space for kindergarten teachers attached. Through this, we intend to propose improvement directions for creating a safe attached kindergarten environment by deriving the components of the indoor space of the attached kindergarten that affects the safety of infants. This study can conclude as follows. First, as the survey showed that the area of the space components had a high influence in all spaces, and the influence of the space components on the safety perception of each space was different for each space except the area, it was necessary to plan the space separately. Second, the entrance space with the lowest awareness of living safety has the highest influence on spatial safety awareness, so it is necessary to consider door plans that can be used safely by infants, such as installing anti-fingertility devices, removing thresholds, and installing market windows. Finally, the corridor/hall space, which has the lowest awareness of criminal safety, needs to be planned in an open structure that is easy to monitor and supervise teachers while securing a corridor/hall space for attached kindergartens. In future research, it is necessary to find a way to secure safety for the entire attached kindergarten space by expanding its area not only to the indoor space but also to the outdoor space of attached kindergarten students.

The AZ91D Magnesium (Mg) Alloy is broadly known as an attractive material with many applications ranging from military goods and aerospace to automobile applications due to its excellent properties in lightweight, machinability, and castability. Unfortunately, Mg Alloys are also prone to corrosion resulting in degradation of the components, which can lead to severe component failure and injuries. Thus, corrosion prevention is required for the AZ91D Mg alloy to increase its performance in the environment. This paper uses the anodising method to study the influence of Zinc Nitrate’s electrolyte concentrations on anodic coated AZ91D Mg Alloys. This method formed a thin film layer on the AZ91D Mg Alloy’s samples known as an anodic film, which can potentially reduce the corrosion activity on the surface of the substrate. To investigate the corrosion activity of the anodised samples, the corrosion rate value was calculated by immersion of coated samples in a salt solution. The coated and corroded surfaces' morphology, structure, and thickness are observed using a Scanning Electron Microscope (SEM). At the same time, the element content of the material will be determined using X-ray diffraction (XRD). Thus, the resulting influence of Zinc Nitrate electrolyte concentration by anodising method shows which concentration value successfully formed the best Zinc Oxide (ZnO) coating layer on AZ91D Mg Alloy samples. Furthermore, an anodisation method using suitable concentrations of Zinc Nitrate electrolyte can be further developed to form an appropriate surface treatment for automotive applications in resisting corrosion in its environment.
Analysis of Multilevel Otsu Thresholding for Corrosion Rate of Anodised AZ91D Magnesium Alloy ​

Magnesium and its alloy are renowned for their high strength-to-weight ratio, excellent machinability and good castability, making it a favourable material for manufacturing various automotive parts. But when exposed to the environment, magnesium and its alloy have a weak ability to resist corrosion. AZ91D magnesium alloy was anodised and immersed in a salt solution to accelerate deterioration. The image of the corroded surface resulting from the immersion test was analysed by quantising the corroded regions. This paper studies the feasibility of an image processing approach using the multilevel Otsu thresholding method by quantising the corroded region on the AZ91D magnesium alloy. This method converts the original colour image to a greyscale image and then converts it to a binary image and RGB image for the multilevel thresholding. The pixel distributions from the multilevel Otsu thresholding display a trend that, with a higher corrosion rate, the pixel’s frequency of occurrence shifted more to the darker regions. This conforms with the Otsu thresholding, where the darker region is identified as the corroded area of the AZ91D magnesium alloy. By implementing the negative image, the binary image is segmented into non-corroded and corroded areas and labelled as 0 (black) and 1 (white,) respectively. As for multilevel Otsu thresholding, the RGB image is assigned in three colours representing different corrosion severity regions. The regions of the corrosion severity are categorised into severe corrosion, moderate corrosion and low corrosion, coloured in dark blue, light blue, and yellow, respectively. Thus, the trend of the corrosion activity can be seen by implementing the multilevel Otsu thresholding and correlating it with the corrosion rate value. Furthermore, obtaining data on corrosion attack severity can provide helpful information in predicting a component’s failure and future maintenance planning.

Time and Death: Heidegger’s Temporality in The Magic Mountain

Time, is a classical motif both in Thomas Mann’s The Magic Mountain and Heidegger’s ontology. Reading The Magic Mountain in terms of Heidegger’s ontology helps us generate a totality view of temporality in Heidegger’s sense and a fresh approach to interpreting the age-old discussion in the novel. This essay attempts to offer up Heidegger’s ontology on time and death as a way of revisiting the classical motif — the meaning of time that illuminated in Thomas Mann’s narrative experiment, the Zeitroman or time novel. The novel’s portrayal of death makes it possible for Hans Castorp, the protagonist of the novel, to understand ‘authentic temporality’ what Heidegger calls ‘the meaning of the Being’. In this sense, the bewitchment of the magic mountain lies in the magic of time and death. Castorp’s closeness to death enables him to understand death in the authentic way, which is in Heidegger’s words, ‘enter into death advance’ or ‘Being-towards-death’ and experience a ‘free and pristine’ state, as Mann puts it. By extension, the experience of Castorp provides readers a perspective of apprehending Heidegger’s ‘Dasein’ and ‘authenticity’. Dasein or Castorp is not Being only to grow to well understand himself or live a new life under the influence of illness and death as many protagonists in conventional Bildungsroman, but Being that understands himself in terms of his Being-experiencing time’s authentic temporality in authentic ‘Being-a-whole’ through ‘Being-towards-death’.

Literature has shown that breastfeeding success depends on breastfeeding support as breastfeeding until six months is a major challenge for most mothers. In breastfeeding research, the early cessation of breastfeeding is described as the biggest challenge. Many mothers have decided to stop breastfeeding because of a lack of support at home, at work, and in the community. The problems for working mothers derive from their work commitment or workplace support. As for stay-at-home mothers, their challenges stem from the pressure of close relatives on conventional myths and erroneous breastfeeding knowledge. New mothers are often given misinformation on breastfeeding. The use of the Internet and social media to obtain lactation information or support for breastfeeding has been widely discussed in the literature at this time. Studying how social capital may be built through the use of technology is imperative. Incorporating social capital into building healthier communities is crucial to help more women choose and continue to breastfeed. Thus, breastfeeding advocacy in Malaysia needs holistic approaches to protection, promotion, and support aspects. Establishing trust-based networks means not only building strong connections but also improving the dependability of those connections between families, communities, and organizations.

The evolution in advertising has shifted the reliance of advertisers from printed materials to video advertisements. Globally, various industries especially the cinema industry, have adopted this form of advertising to meet their marketing goals. Yet, video advertisements are still considered ineffective. Thus, the study set out to find out the perceptions of the cinema viewers on visual communication elements in cinema video advertisements, analyse the effectiveness of the cinema video and determine the mean differences in the effectiveness of the elements in video advertisements across gender, education level and age. It is a cross-sectional survey study using the causal-comparative approach. 240 Universiti Teknologi MARA (UiTM) Shah Alam and Management and Science University (MSU) students participated in the study. TGV Cinemas and Golden Screen Cinemas were selected as the sampled video advertisements. The questionnaire used was adapted from [2], [3] and [33]. It was revealed that the image and video shots were positively perceived as the most effective communication elements in delivering the messages compared to other visual communication elements and the cinema video advertisements were comprehensible, yet they were not highly effective as an advertising platform since the advertising objectives were not achieved. In addition, the analysis of the demographic factors showed that there were significant mean differences between the four visual communication elements and age groups. Thus, the study suggests advertisers incorporate more creativity in producing interactive and immersive video advertisements to optimise the effectiveness of their advertisements.
Muslims in the Post-pandemic World: The Call to Balance Individual Freedom and Community Rights?

Moving into the post-pandemic world, many studies have been conducted to learn the best responses of countries and institutions in dealing with related issues and emerging consequences, and several key areas were investigated such as healthcare, financial and political responses, whereupon numerous factors of their success have been highlighted. There is no doubt, however, that community participation is extremely crucial to remedy the situation in many sectors including politico-economic restoration and education. The conflict between the right to pursue individual freedom and the moral obligation to keep the community safe from the impact of the pandemic has also been the subject of philosophical inquiries. This paper explores the concept of community in Islam in light of the above discussion. It begins with discussing the commonly recognised concepts of the duty of individuals (farḍ ʿaynī) and the duty of sufficient execution (farḍ kifāʾī/kifāyah). The author argues that the concepts do not correspond to the highlighted discussion and the discussion is losing the clear definition of what should be regarded as the constant obligation of the whole community as a single unit and not only “some” of the community as present in the ʿaynī-kifāʾī division. This opinion paper calls for the establishment of the middle space or hybrid space in dealing with the notion of rights and obligations in the post-pandemic world.

This study aims at analysing the disparity of the feline representations with the search for their cross-cultural differences between English and Malay feline proverbs. It is an attempt to scrutinize the influence of distinctive cultural backgrounds behind the inauguration of feline representations in the proverbs. The Great Chain of Metaphor Theory (GCM) framework by Lakoff and Turner (1989) is utilised in the process to achieve the purposes of this study, with a focus on the four components, namely the Naïve Theory of the Nature in Things, the Great Chain of Being, the Generic is Specific Metaphor, and the Maxim of Quantity; to explore the differences based on the cross-cultural factors in the proverbs. The findings from this study indicate that customs, religion, and the core values of the particular cultural background, with the touch of favouritism, existence in the surroundings, and the top position of the feline animals, are the factors that influenced the different representations generated within the cultural notions. This study helps to fill the gaps of past research on the comparison and contrast analysis of proverbs between different languages, particularly the English and Malay languages, besides adding new insights on the cross-cultural aspects, which would be beneficial for language learners, primarily foreign learners, to enhance their cultural knowledge.
