The 1930s and 1940s were characterised by considerable interest in research on literary magazines. Relevant studies were undertaken by A.M. Uys (1933, UCT), P.J.J. Dry (1939, UOFS) and W.G. Combrinck (1945, UW). This interest dwindled until J.H. Venter registered a doctorate at UNISA (1991), which he never completed. Today there is a vast gap in the field of research on Afrikaans literary magazines in general. Since no other research has yet been undertaken on the document design of literary magazines in particular, this study may be regarded as groundbreaking. Document design focuses on the utilisation of design elements to purposely create a document for optimal use by the reader. Renkema’s CCC model was chosen to serve as a generic, theoretically founded model for document analysis. In accordance with this model, texts were analysed and reviewed with regard to genre, content, structure, style and layout. Renkema’s model was adapted in order to fine-tune it for reviewing the document design of literary magazines in particular. In this study the choice of genre fell on literary magazines and little magazines of the 1960s (Sestiger, Wurm, Kol and Standpunte), the 1980s (Spado, Graffier, Stet and Standpunte) and the era of 2000 (Driepootpot, PENorent, seepdoos, Tydskrif vir Letterkunde and Spilpunt). The object of this study was to determine whether the parameters governing the document design of literary magazines changed over a period of forty years. The content of these magazines was analysed by classifying it in various subgenres and then comparing the number of writers who contributed to every subgenre in every magazine; the internal and external structure of the various magazines were defined and compared; the style of the various magazines was established and compared; and, lastly, the layout of the twelve magazines was explored and similarities, differences and progression were established. The results indicated that some of the parameters of document design have indeed changed over the past forty years, but that a large number of principles also remained unchanged. The content expanded significantly as a result of the addition of new subgenres. The internal structure remained consistent. The quality of the external structure and layout improved in such a way that it supports the internal structure much better. The style of the content remained unchanged for those magazines that belong to the same era, but changed through the decades to reflect the actualities and struggles of the day. Layout is the area in which the greatest measure of progression was recorded, mainly as a result of the expansion of knowledge in the field of document design, the evolution of technology in the form of the Internet, the layout process, the printing process, et cetera. These developments have, in the course of time, made it substantially easier to design documents for a specific purpose and target audience. / Dissertation (MA)--University of Pretoria, 2006. / Unit for Academic Literacy / Unrestricted

Bakgrund: De senaste åren har svenska privatpersoner aktiehandel ökat markant. Det låga ränteläget tillsammans med lägre entrébarriärer har resulterat i att ett stadigt inflöde av nya användare har tillkommit till plattformar för aktiehandel. Det är dock ingen lätt uppgift att skapa överavkastning. Föreliggande studie ämnar undersöka om det med hjälp av relativvärdering kan skapas en strategi som konsekvent kan skapa en riskjusterad överavkastning. Studien har valt att fokusera på den nordiska verkstadsindustrin, som historiskt har gett en stabil avkastning och innehåller flera väletablerade företag. Syfte: Studiens syfte är att analysera om man med hjälp av nyckeltalen P/E, EV/EBITDA, P/B, EV/S och förändring av Cash Conversion Cycle kan skapa riskjusterad avkastning på nordiska verkstadsföretag som är högre än jämförelseindex under perioden 2012–2022. Metod: För att uppfylla studiens syfte har en kvantitativ studie med en deduktiv ansats använts. Ett urval ur Nasdaqs listade industriaktier med rensade från producerande och finansiella företag har använts för att skapa portföljer baserade på P/E, P/B, EV/S, EV/EBITDA och ΔCCC. Totalt 10 portföljer skapades, 5 baserade låga respektive 5 på höga nyckeltal. Portföljerna har sedan ombalanserats årligen, den observerade avkastningen har sedan riskjusterats och satts emot ett jämförelseindex. Resultat: Höga EV/EBITDA-, höga EV/S-, låga EV/EBITDA-, låga EV/EBITDA- och störst negativ ΔCCC-portföljerna presterade överavkastning under den aktuella perioden mellan 2012–2022 för verkstadsföretag i Norden. Portföljen som bestod av höga EV/EBITDA-aktier skapade högst riskjusterad avkastning. Totalt presterade 50% av portföljerna högre riskjusterad avkastning än jämförelseindex. Ingen av de överpresterande portföljerna visade sig vara signifikanta. / Background: In recent years, Swedish private equity trading has increased markedly. The low interest rate in addition to fewer entry barriers have resulted in a steady influx of new users of stock trading platforms. However, creating excess returns is no easy task. This study intends to investigate whether, with the help of relative valuation, a strategy can be created that can consistently create a risk-adjusted excess return. The study has chosen to focus on the Nordic manufacturing companies, which has historically provided a stable return and includes several well-established companies. Purpose: The purpose of the study is to analyze whether the key figures P/E, EV/EBITDA, P/B, EV/S and Changes in Cash Conversion Cycle can create a risk adjusted return on Nordic manufacturing companies that is higher than the comparable stock index during the period 2012–2022. Method: To fulfill the purpose of the study, a quantitative study with a deductive approach has been used. A sample of Nasdaq listed industrial shares cleared of non-producing and financial companies has been used to create portfolios based on P/E, P/B, EV/S, EV/EBITDA and ΔCCC. A total of 10 portfolios were created, 5 based on low and 5 on high key figures. The portfolios have since been rebalanced annually, the observed return has since been risk adjusted and compared against a comparable index. Result: High EV/EBITDA-, high EV/S-, low EV/EBITDA-, low EV/EBITDA- and the largest negative ΔCCC portfolios achieved excess returns during the period between 2012–2022 for manufacturing companies in the Nordic countries. The portfolio consisting of high EV/EBITDA stocks created the highest risk-adjusted return. In total, 50% of the portfolios performed higher risk adjusted return than the benchmark index. None of the overperforming portfolios proved to be significant.

本研究選取台灣加權股價指數、日經225股價指數、南韓綜合股價指數、新加坡海峽指數以及香港恆生指數，從1990年1月5日至2004年12月31日之指數收盤週資料，利用動態條件相關係數（DCC）模型來探討台灣、日本、南韓、新加坡以及香港股票市場間相關係數的動態過程。經由實證本研究歸納結論如下三點： 一、台灣、日本、南韓、新加坡以及香港五個國家股價指數兩兩間的相關係數是會波動的，如同指數在不同時點因事件發生的條件不同而波動一樣，相關係數亦會隨時間點事件發生的條件而改變，不若常數條件相關係數只為固定正值，且受選取時間區間的影響。 二、五個國家由於政經發展相似，且地理與文化背景亦相近，相關係數除台灣－日本、台灣－新加坡以及日本－香港在某些時點為負值外，其餘任何時點皆為正數，與直覺相符。此外，由圖形直觀之，我們發現新加坡－香港的連動程度最高，且除台灣－日本的走勢波動較大而不明顯外，其餘動態相關係數的走勢和緩，在某些時段下還有明顯的趨勢，因此若機構投資人在投資此一區域時，能考量此一趨勢的存在，將能更有效率的運用投資基金；而發行標的為此五個國家股價指數的衍生性金融商品時，發行機構將能更有效的規避風險。 三、現代投資學倡導投資組合管理，其中心理念是藉由資產間的負相關，使得投資報酬不會因非系統風險而降低，對個股而言，指數投資即為分散非系統風險的方法之一；然對區域而言，分散投資個別國家才能達到投資組合最佳化。我們以1997、1998年亞洲金融風暴一例觀察，雖然亞洲金融風暴對亞洲國家而言是全面的，為不可分散的系統風險之一，但由於亞洲各國發生金融危機的時間點不同，因此由圖形中我們可以看出，在亞洲金融風暴時，五個國家股價指數的動態相關係數反而迅速降低，因此投資此五個國家符合資產配置最佳。

Continuous colormaps are integral parts of many visualization techniques, such as heat-maps, surface plots, and flow visualization. Despite that the critiques of rainbow colormaps have been around and well-acknowledged for three decades, rainbow colormaps are still widely used today. One reason behind the resilience of rainbow colormaps is the lack of tools for users to create a continuous colormap that encodes semantics specific to the application concerned. In this paper, we present a web-based software system, CCC-Tool (short for Charting Continuous Colormaps) under the URL https://ccctool.com, for creating, editing, and analyzing such application-specific colormaps. We introduce the notion of “colormap pecification (CMS)” that maintains the essential semantics required for defining a color mapping scheme. We provide users with a set of advanced utilities for constructing CMS’s with various levels of complexity, examining their quality attributes using different plots, and exporting them to external application software. We present two case studies, demonstrating that the CCC-Tool can help domain scientists as well as visualization experts in designing semantically-rich colormaps.

This master thesis deals with extension of the univariate GARCH model to multivari- ate models. We present individual models and deal with methods of their estimation. Then we describe some statistical tests for diagnosting the models. We have programmed in the statistical software R one of them - the Ling-Li test. Afterwards we apply selected models to real data of stock market index S&P 500, stock market index Russell 2000 and stocks of crude oil. For the GO-GARCH model, we compare all available estimation methods and show their differences. Then we compare the results of all models with each other and also with univariate models in terms of estimates of conditional variances, estimates of conditional correlations and also in terms of computational complexity. 1

Global climate change concerns help shape current environmental regulations, which increasingly seek to reduce or capture CO2 emissions. Methods for capturing CO2 emissions from energy processes have been the focus of numerous studies to provide support for those seeking to reduce the environmental impact of their processes. This research has (1) simulated a baseline case of energy-storing cryogenic carbon capture for implementation on a 550 MWe coal fired power plant, (2) presented a novel cryogenic carbon capture process for removing CO2 from natural gas down to arbitrary levels, (3) presented a natural gas liquefaction process that has the ability to be highly CO2 tolerant, and (4) developed theoretical models and their experimental validation of CO2 capture predictions for all aforementioned processes.

This study assessed the influence of language on the ability of children identified as being at risk for internalizing behavior disorders to successfully participate in a social skills intervention program. Fourth and fifth grade students participated in Strong Kids: A Social and Emotional Learning Curriculum in Grades 4-8, a program which promotes emotional resiliency. The Clinical Evaluation of Language Fundamentals-Fourth Edition (CELF-4) and Children's Communication Checklist-Second Edition (CCC-2) were both completed to obtain a global language score and pragmatic language score. The Teacher's Report Form (TRF), a shortened 10-item version of the Internalizing Student Symptom Scale (ISSC), and a 20-item knowledge based assessment relating to the Strong Kids curriculum were completed prior to and after the intervention. These behavioral assessments were administered in order to determine improvement in academic performance, adaptive functioning, and behavioral/emotional problems with relation to language functioning. It was found that children with higher general language abilities made significantly positive improvements with regard to withdrawal than children with lower general language abilities on measures taken prior to and directly after the Strong Kids curriculum. Additionally, the ISSC revealed that children with lower general language abilities rated themselves as having significantly more positive changes in behavior than children with higher general language abilities on measures taken prior to and six weeks following the Strong Kids curriculum. Pragmatic functioning, determined by the CCC-2, was not associated with significant behavioral improvements between children with high and low pragmatic language skills.

The industrial revolution came with its downside of emission of greenhouse gases into the atmosphere. The NOAA reported in 2019 that, of the greenhouse gases emitted into the atmosphere, CO2 contributed to about 80% of the increased greenhouse gases hence the need for CO2 Sequestering and Storage (CSS) and ultimately leading to Carbon Capture and Recycling (CCR) as a viable option to convert CO2 into useful forms. The race to find the best catalyst for CCR has led to the synthesis of many organometallic compounds. Pincer complexes catalyzed CO2 reduction has gained notoriety recently because of the tunability and robustness without causing any alteration in their overall coordination geometry. Different metals and pincer motifs have been reported for the electrocatalytic and photochemical reduction of CO2. Chapter I introduces the broader project impact, N-heterocyclic carbene concepts, pincer chemistry, iron pincer chemistry, and N-heterocyclic pincer complexes of Fe for a comprehensive perspective. Chapter II addresses the scarcity of iron based NHC pincer complexes due to deprotonation challenges and octahedral coordination preferences. Bulky substituents like mesityl, adamantly, or DIPP enable mono-ligated pincer complexes by hindering ligand encapsulation, leaving no open coordination site. In-situ metalation / transmetalation, and isolated CCC-NHC Zr complexes are presented along with a method to convert between mono-ligated and bis-ligated complexes. Chapter III explores L-type ligands' reactivity to prevent ligand reorganization around the Fe center from Chapter I. Chapter IV covers CCC-NHC Fe pincer complexes' synthesis, characterization, and transient absorption studies of bis-ligated complexes. Characterization of the CCC-NHC pincer Fe complexes in Chapter I-IV were carried out using 1H and 13C NMR spectroscopy, ESI-TOF MS, EA (Elemental Analysis), cyclic voltammetry, and X-ray diffraction. Chapter V discusses catalytic experiments and data consistent with preliminary CO2 reduction with mono-ligated CCC-NHC pincer complexes.

Muitos setores sociais apoiaram o golpe e a ditadura civil-militar brasileira (1964-1985). Uma parcela dessas pessoas se organizou em grupos para realizar atividades terroristas, com o objetivo de disseminar o medo e a insegurança entre a população, contribuindo para a manutenção de um Estado autoritário. O mais conhecido desses grupos foi o Comando de Caça aos Comunistas, conhecido pela sigla que assinava em suas atividades: CCC. Essas atividades ocorreram em várias cidades do Brasil entre 1968 e 1980, e consistiram em explosões de bombas, pichações e destruições de alvos como bancas de jornais e revistas, teatros, universidades, imprensa, setores da Igreja Católica; também faziam ameaças, atentados à vida, sequestro e assassinato de: artistas, estudantes, religiosos, jornalistas e políticos. A proposta deste trabalho é apresentar e analisar essas atividades, sob a ótica do terrorismo e da impunidade que, verificou-se, permearam todas as ações assinadas por aquela sigla. Para a realização da pesquisa foram utilizadas fontes impressas como meios de comunicação, documentos oficiais do Brasil, diários de Assembléias Legislativas estaduais e entrevistas publicadas. / Many social sectors supported the coup d‘état and the civil-military dictatorship in Brazil (1964-1985). A portion of those people organized themselves into groups to carry out terrorist activities, aimed at spreading fear and insecurity among the population, contributing to the maintenance of an authoritarian state. The most well-known of these groups was the Command in Pursuit of Communists, known by the Portuguese acronym of those activities: CCC. These activities occurred in several cities in Brazil between 1968 and 1980, and consisted in bombings, graffiti and destruction of aims like newsstands, theaters, universities, media, sectors of the Catholic Church; as well as threats, attacks against life, kidnapping and murder of: artists, students, clergy, journalists and politicians. The purpose of this paper is to present and analyze these activities, from the perspective of terrorism and impunity which permeated all actions carried out under that acronym. For the research, sources such as printed media outlets, official documents of Brazil, diaries from state Legislative Assemblies and published interviews were used.
