Challenges in the implementation of employment equity act : a case study of the University of LimpopoPhaduli, Takalani Violet January 2020 (has links)
Thesis (MPA.) -- University of Limpopo, 2020 / The purpose of this study was to investigate challenges in the implementation of Employment Equity Act in the University of Limpopo. The design of the research in this study is both qualitative and quantitative. Data were collected from HODs and Human Resources Officers. Structured interviews and questionnaires were used to collect data form the participants. Data were analysed quantitatively and qualitatively. Results revealed that there are more males in Senior Management levels than females in the University. Data further showed that the majority of Senior Management fall under age category 50-64 years old. The results show that most of the respondents hold highest qualifications which is masters and doctoral degree. It was found that most of the respondents are from Sepedi and Tshivenda speaking communities. The finding revealed that the University of Limpopo has been implementing the Employment Equity Act. However, the implementation of the EEA encountered certain challenges including among other resistant to change, poor networking, lack of employment equity awareness, undermining of the HR Officers by Selection Committee members and lack of qualified people with disabilities in certain positions.
Another finding shows that the University has Employment Equity Plan with numerical target to be achieved. It found that the successful implementation of EEA will address the problem of unfair discrimination that people suffered as a result of race, gender, disability and sexual orientation. The findings further show that the University is strictly adhering to the stipulations of the EEA. It was found that employees in the University are not well informed of the Employment Equity Policies. Another finding shows that the University Employment Equity has been a very useful tool to promote equality in the University. The study recommends that the University should not deviate from the EEA especially when filling positions reserved for designated groups. It is recommended that HODs should familiarize themselves with the Act. It is recommended that the University use provincial demographics to set the EE targets. University must have EE Plan targets on the agenda at all meetings of the University’s Executive Committees. It is recommended that further discussion and monitoring need to be conducted at Executive Management level.

Solitary objects on quantum spin ringsShchelokovskyy, Pavlo 16 December 2004 (has links)
We investigate whether quantum spin rings with nearest-neighbor Heisenberg or Ising exchange interactions can host solitary states. Using complete diagonalization techniques the system is described without classical or semiclassical approximation. In this case definitions used in connection with classical solitons are not applicable, one needs to redefine what solitary objects on a quantum spin system with translational symmetry ought to be. Thus, we start our contribution by defining which quantum states possess solitary character. In addition we discuss useful observables in order to visualize solitary quantum states. Then we demonstrate for various quantum spin rings that solitary quantum states indeed exist, and that they are moving around the spin ring without changing their shape in the course of time.

Formulation and characterization of lipid-based nanocarriers for the delivery of antimicrobial peptideSaha, Srijani January 2022 (has links)
Bakterier som är resistenta mot antibiotika har de senaste åren blivit ett stort hot mot mänskligheten. Att utveckla nya antibiotikaläkemedel är väldigt tidskrävande samt kommer med en dyr prislapp. Det är några av anledningarna att forskare har inriktat sig på antimikrobiella peptider (AMPs) som ett alternativ till traditionella antibiotika. Dessa peptider finns i alla levande organismer och uppvisar en snabb och ospecifik mekanism. Vidare så är de mindre benägna att utveckla resistens hos bakterierna. Däremot så har dessa AMPar visat sig ha låg stabilitet och en del toxiska biverkningar. Olika typer av nanobärare kan användas för att överkomma dessa kommakortanden. Syftet med denna studie var att utveckla en optimerad nanobärare för AMPen AP114. Peptiden har blivit inkluderad i nanostrukturerade lipidbärare (NLC) samt liposomer. Dessa har producerats med smält emulsifieringsmetod och lösningsinjektion metoden. De fysikalkemiska karaktäristik hos olika blanka samt AP115 laddade nanoformuleringar har analyserats samt jämförts. Resultaten indikerade att liposomformuleringarna hade den lägsta partikelstorleken och storleksfördelning men en kontrollerad in vitro frisättning av peptiden över 48 timmar. Generellt, så indikerar de preliminära resultaten en potential nanoformulering för peptiden AP114. / In the past few years, bacterial resistance to antibiotics has posed a major threat to humankind. Development of substitutes for traditional antibiotics is a highly time consuming and expensive venture. For this reason, researchers are focusing on using antimicrobial peptides (AMP) as an alternate. These peptides are found in all living organisms and exhibit a fast and non-targeted mechanism of action. Besides, they are less susceptible to microbial resistance. However, these therapeutic peptides are not stable and have toxic side effects. To overcome these limitations, drug delivery systems have been explored. In this study, the aim was to develop an optimized drug delivery system for AP114. The peptide has been encapsulated in nanostructured lipid carriers (NLC) and liposomes, produced by melt emulsification method and solvent injection method, respectively. The physicochemical characterization of different blank and AP114 loaded nanoformulations were analyzed and compared. The results indicated the liposome samples to have the lowest particle size distribution and polydispersity, with a controlled in vitro release of the peptide over 48 hours. Overall, these preliminary findings suggest a promising potential for the formulation of a nanocarrier for AP114 peptide.

Reoxidation of Liquid Steel during Casting : Observation of Non-Metallic Inclusions on Carbon Steel SamplesCollard, Sofia, Tamim, Imane, Chumbe Zevallos, Anna-Sara January 2024 (has links)
Reoxidation is a phenomenon that occurs in steel products during the initial stage of the formation of liquid steel, mainly during casting. This leads to the formation of inclusions which is a common problem that affects the properties, such as strength and ductility of the steel, and thus decreases its quality. To investigate these inclusions an electrolytic extraction and a scanning electron microscope(SEM) were performed on four carbon steel samples taken before and throughout continuous casting. To get a better understanding of the inclusions, the chemical composition, morphology, and sizes were analyzed, these were measured with the software ImageJ. As a result, five types of inclusions were identified, these include reoxidation, deoxidation, desulphurization, and complex compositions. Each type was represented by specific compounds and elements, such as FeO for reoxidation inclusions and Al2O3 for deoxidation inclusions. Additionally, inclusion morphology and size were significant classification factors, with film inclusions presenting larger sizes compared to other types, while spherical inclusions were observed perfectly, spherical ones were often associated with pure FeO content. Despite successful electrolytic extraction and SEM analysis, the number of inclusions obtained was lower than expected due to the presence of an additional layer of carbides. Future research may benefit from additional heating treatments to facilitate deeper analysis of inclusions. / Reoxidation är ett fenomen som uppstår i stålprodukter under gjutning. Detta leder till bildning av inneslutningar vilket är ett vanligt problem som påverkar egenskaperna, såsom hållfasthet och formbarhet hos stålet, och därmed minskar dess kvalitet. För att undersöka dessa inneslutningar utfördes en elektrolytisk extraktion och en SEM på fyra kolstålprover tagna före och under stränggjutning. För att få en bättre förståelse av inneslutningarna analyserades den kemiska sammansättningen, morfologin och storlekarna, dessa mättes med programvaran ImageJ. Som ett resultat identifierades fem typer av inneslutningar, dessa inkluderar reoxidation, deoxidation, avsvavling och komplexa kompositioner. Varje typ representerades av specifika föreningar och element, såsom FeO för reoxidationsinneslutningar och Al2O3 för deoxidationsinneslutningar. Dessutom var inklusionsmorfologi och storlek signifikanta klassificeringsfaktorer, med filminneslutningar som presenterade större storlekar jämfört medandra typer, medan sfäriska inneslutningar, observerades perfekt sfäriska sådana var ofta associerade med rent FeO-innehåll. Trots framgångsrik elektrolytisk extraktion och SEM-analys var antalet erhållna inneslutningar lägre än förväntat på grund av närvaron av ytterligare ett lager karbider. Framtida forskning kan dra nytta av ytterligare värmebehandlingar för att underlätta djupare analys av inneslutningar.

Självskadebeteende och Expressed Emotion. En uppföljning av IKB-Intensiv Kontextuell Behandling. / Self-harm behaviour and Expressed Emotion. A follow-up of ICT-Intensive Contextual Treatment.Selberg, Malin January 2016 (has links)
Att avsiktligt skära, bränna eller på annat sätt skada sig själv illa är förenat med ett stort lidande och väcker ofta starka reaktioner hos de anhöriga. Problematiken är omfattande och självskadebeteende förefaller vara en stark prediktor för självmordsförsök och fullbordade självmord. Globalt är självmord den näst vanligaste dödsorsaken bland ungdomar. Efterfrågan på effektiva behandlingsmodeller för denna målgrupp är stor. I Sverige, närmare bestämt i Uppsala har behandlingsmodellen IKB – Intensiv Kontextuell Behandling utvecklats för ungdomar med självskadebeteende och/eller suicidala beteenden och deras familjer. Modellen är en integrerad individ- och familjeterapeutisk behandlingsmodell. Föreliggande studie syftade till att undersöka behandlingsmodellen IKB:s effektivitet i förhållande till minskat självskadebeteende hos ungdomarna och minskade nivåer av Expressed emotion hos föräldrarna. Sammanlagt har 34 familjer deltagit i studien och de har samtliga genomgått behandling inom ramen för IKB-modellen. Resultatet visade på en effektivitet i behandlingsmodellen IKB avseende att minska självskadebeteende hos ungdomarna samt att minska nivåerna av Expressed emotion hos föräldrarna. Utfallet av studien diskuteras utifrån tidigare forskning och metodologiska frågor. / To intentionally cut, burn or hurt oneself severely is associated with great suffering and often arouse strong reactions within the family context. The problem is extensive and self-harm appears to be a strong predictor of suicide attempts and completed suicides. Globally, suicide is the second leading cause of death among young people. Effective treatment models for this group is urgent. In Sweden, (Uppsala) the model IKB - Intensive Contextual Treatment was developed for adolescents with self-harm and / or suicidal behavior, and their families in order to provide support. IKB is an integrated individual and family therapeutic model. The aim of the study were to evaluate the effectiveness of IKB in relation to frequency of self-harm and levels of Expressed emotion. A total of 34 families participated in the study and they all received treatment in the context of the IKB-model. The families completed the self-assessment forms for data collection before treatment, after treatment and follow-up. Results showed efficiency to reduce self-harm among adolescents and to decrease levels of Expressed emotion. The outcome of the study are discussed based on previous research and methodological issues. / <p>27</p>
