Entrepreneurship education and training ensures economic development by enabling the creation of thriving new businesses and jobs by entrepreneurs. The Business Management Training Programme is tasked with training young entrepreneurs in South Africa. However, the youth unemployment rate has been exceedingly high in recent years. This study seeks to explore the implementation challenges being experienced by the Business Management Training Programme at the National Youth Development Agency. Using a qualitative approach, this study made use of semi-structured interviews with a carefully selected sample of those involved in the management and implementation of the Business Management Training Programme. A thematic analysis of the semi-structured interviews indicated that the challenges experienced in the implementation of the programme did not stem solely from operational issues within the National Youth Development Agency, but from the conceptualisation and design of the Business Management Training Programme. On this basis, it is recommended that the National Youth Development Agency use the Design and Architecture Framework for Entrepreneurship Education and Training to conceptualise and design their own Business Management Training Programme. The study concluded that by conceptualising and designing its own programme, the National Youth Development Agency will be able to address the unique entrepreneurial education and training challenges being experienced in South Africa. / Public Administration and Management / M.

In classical “triple bottom line” sustainability reporting, there have not been any clear guidelines on how companies should report on their environmental footprint. Consequently, the transparency in the environmental reporting has been low, which has resulted in greenwashing. To create reliable reporting and increase the proportion of green loans and green investments, the EU introduced the classification system EU Taxonomy in 2021. The new framework has stricter requirements on companies as they are now obligated to report on specific guidelines. These guidelines will also allow stakeholders to determine how sustainable a company is. Since the EU Taxonomy was recently launched, there has been a knowledge gap in how companies experience the framework. Also, what measures should be considered in the design of the EU Taxonomy for the implementation to be as successful as possible, based on the premise that companies should make their business model as sustainable as possible. This semi-structured interview study examines how Swedish companies experience the EU Taxonomy. The researchers interviewed eight Swedish stakeholders with great insights into the area, from the manufacturing industry (1), the Real Estate Industry (2), the Swedish Corporate Business Organizations (1), the Real Estate Industry Organizations (2), and Auditing Firms (2). The researchers could conclude that being classified as sustainable in the EU Taxonomy does not necessarily mean a company is sustainable from a scientific point of view. Nevertheless, it can be an answer to political interests. The interviewees also felt it was challenging to interpret and understand the framework and that there were necessary clarifications. Further, the EU will have to account for several activities from each industry so that companies can report on their total ecological footprint. Finally, changes in the delegated acts are mandatory for the EU taxonomy to be a successful policy instrument. / I klassisk “triple bottom line” rapportering har det inte funnits några tydliga riktlinjer för hur företag ska rapportera om sitt ekologiska avtryck. Som en följd av detta, har transparensen i hållbarhetsredovisningen varit låg, vilket har resulterat i greenwashing. I syfte att skapa mer tillförlitlig rapportering och öka andelen gröna lån och investeringar, infördes 2021 klassificeringssystemet EU Taxonomin. Det nya ramverket har skapat nya krav på företag då de nu är skyldiga att rapportera på specifika miljöbelastande aktiviteter. Dessa riktlinjer ska dessutom kunna utgöra hur hållbara de rapporterande bolagen är. Eftersom EU Taxonomin nyligen har lanserats, fanns det en kunskapslucka för hur företag upplever ramverket. Även vilka åtgärder som bör övervägas i utformningen av EU-taxonomin för att implementeringen ska bli så framgångsrik som möjligt, utifrån utgångspunkten att företag ska göra sin affärsmodell så hållbar som möjligt. Med detta i åtanke utvecklades denna semistrukturerade intervjustudie som ämnar att undersöka hur svenska företag ser på EU Taxonomin. Forskarna har intervjuat åtta aktörer från svenska: tillverkningsindustrin (1), fastighetsbranschen (2), näringslivet (1), medlemsorganisationer inom fastighetsbranschen (2) och revisionsbyråer (2). Det forskarna kunde konstatera är att det som klassas som hållbart i EU Taxonomin, inte nödvändigtvis ur ett teknikneutral och vetenskapligt perspektiv är hållbart, utan är ett svar på ett politiskt intresse. Aktörerna upplever dessutom att ramverket är svårt att förstå och att det därför är nödvändigt med förtydningar. Till sist kommer även EU behöva ta fler aktiviteter från de respektive branscherna i åtanke i de delegerade akterna, för att företag ska kunna redovisa för sitt totala ekologiska fotavtryck. Slutligen är ändringar i de delegerade akterna obligatoriska för att EU Taxonomin ska kunna bli ett framgångsrikt policyinstrument.

Η υλοποίηση πρακτικών ασύρματων συστημάτων επικοινωνίας δεδομένων στην τεχνολογία UWB παρουσιάζει ιδιαίτερες προκλήσεις, κυρίως λόγω της χαμηλής ισχύος εκπομπής και της πολύ σύντομης διάρκειας των παλμών που χρησιμοποιούνται, οι οποίοι θα πρέπει να στέλνονται με πολύ μεγάλες ταχύτητες για την επίτευξη των επιθυμητών ρυθμών μετάδοσης. Το κανάλι μετάδοσης είναι ιδιαίτερα επιλεκτικό ως προς την συχνότητα και εξαιρετικά πυκνό και πλούσιο σε πολυοδικές συνιστώσες με αρκετά μεγάλες καθυστερήσεις. Αυτές οι συνιστώσες μπορούν να ανιχνευθούν και να συλλεχθούν χρησιμοποιώντας κατάλληλες δομές δεκτών RAKE, οι οποίοι τις συνθέτουν ώστε να μεγιστοποιηθεί η ενέργεια του ωφέλιμου σήματος, αυξάνοντας την απόδοση του συστήματος. Οι δομές αυτές παρουσιάζουν την καλύτερη απόδοση σε τέτοια συστήματα, αλλά έχουν μεγάλη υπολογιστική πολυπλοκότητα, καθώς για την ικανοποιητική απόδοση του συστήματος πρέπει να συνδυάσουν πολλές συνιστώσες, δεδομένης και της χαμηλής ισχύος εκπομπής της τεχνολογίας. Συνεπώς, για την υλοποίηση ενός πρακτικού και αποδοτικού συστήματος, σημαντικό ζήτημα αποτελεί ο τρόπος επιλογής και συνδυασμού των συνιστωσών μέσω ενός αλγορίθμου που θα χρησιμοποιεί τον μικρότερο δυνατό αριθμό δακτύλων. Στόχοι της διατριβής ήταν η μελέτη της τεχνολογίας UWB, η διερεύνηση των παραμέτρων των παλμικών UWB συστημάτων, η μελέτη και εξομοίωση μοντέλων του καναλιού, η κατανόηση των οποίων είναι απαραίτητη για την αποτελεσματική ανίχνευση του σήματος και τον σχεδιασμό των αλγορίθμων ψηφιακής επεξεργασίας του σήματος, η διερεύνηση δεκτών RAKE καθώς και εναλλακτικών δομών, οι εξομοιώσεις πομποδέκτη παλμικού UWB σε επίπεδο συστήματος με έμφαση στον RAKE και τον εκτιμητή καναλιού, η διερεύνηση παραμέτρων και τεχνικών για την υλοποίηση σε υλικό και τέλος η ανάπτυξη, ο σχεδιασμός και υλοποίηση μιας πρακτικής δομής δέκτη με RAKE αποδιαμορφωτή και εκτιμητή καναλιού που συνδυάζει χαμηλή πολυπλοκότητα και ικανοποιητική απόδοση. Παρουσιάζονται και συγκρίνονται τρεις νέες διαφορετικές προσεγγίσεις σχεδίασης, οι οποίες βασίζονται σε προτεινόμενο υβριδικό αλγόριθμο (HPS) για την μείωση της πολυπλοκότητας του RAKE και δίνονται αποτελέσματα που αφορούν στην αξιοποίηση του υλικού και στις επιδόσεις του συστήματος. Tα αποτελέσματα παρουσιάζουν το trade-off ανάμεσα στην συλλογή ενέργειας, την απόδοση του δέκτη και την πολυπλοκότητά του. Η αποτελεσματικότητα των προτεινόμενων αρχιτεκτονικών επαληθεύεται μέσω ειδικής πλατφόρμας αναδιατασσόμενου υλικού στην οποία υλοποιήθηκε η σχεδίαση. / Τhe implementation of practical wireless data communications systems for the UWB technology is very challenging due to the use of low-power ns-duration pulses which have to be sent in a high-frequency in order to achieve the desirable data rates. The UWB channel is highly frequency selective and it is characterized by dense and rich multipath propagation and large multipath delay spreads in some cases. A RAKE receiver can be employed in order to exploit multipath diversity and effectively capture the desired signal energy which is dispersed over the various multipath components, helping to mitigate fading. However, the particular nature of UWB results in very low-energy paths which, in conjunction with high multipath diversity, leads to a RAKE receiver that must exploit a large number of MPCs in order to optimize the received SNR. Thus, for the implementation of a low-complexity system it is important to define a novel method for the selection and combining of MPCs and develop an algorithm that is able to utilize a minimum number of fingers in the RAKE structure. Our work was focused in the study of UWB technology, the investigation of the parameters of IR-UWB systems, the study and understanding of the channel models which is necessary for the design of practical and efficient DSP algorithms, the investigation of RAKE type receivers as well as other alternative structures, the system-level simulations of the IR-UWB transceiver with emphasis given to the algorithms for the RAKE demodulator and channel estimator, the investigation of the parameters and techniques for the implementation of the system in hardware and finally, the development, design, and implementation of a practical receiver structure that includes a RAKE demodulator and a channel estimator and combines low complexity and satisfactory performance. The ultimate goal of this work is the presentation and investigation of the proposed channel estimator and (MRC)-RAKE receiver architecture which is based on a proposed novel hybrid algorithm called HPS. Three different design approaches aiming to a practical system implementation in an FPGA are proposed and compared and system/algorithm performance, hardware utilization results are provided. The obtained results demonstrate the trade-off between energy capture, performance and receiver complexity. The effectiveness of the proposed architectures is verified on a special FPGA platform which was used for the implementation of the receiver structure.
