Subjects: subject: Engineering, Electronics and Electrical.

description: Two of the main challenges and critical issues facing real-time wireless multimedia transmission are packet loss and transmission errors. This thesis has selected Motion JPEG 2000, the newest standard for still image coding, for real time video streaming. JPEG2000 offers a number of qualities of service and revenue strategies that make it a leading contender for image streaming applications. We offer extra protection for the wireless transmission of JPEG2000 code streams due to error prone and changeable wireless channel conditions, and since the baseline JPEG 2000 error resilience tools are not sufficient in the context of wireless transmissions. Also, to accommodate the video streaming, avoid packet loss, and achieve efficiency, a payload format for JPEG 2000 video streams over the Real-time Transport Protocol has been defined. The main contribution of this thesis is adopting the packetization strategies and proposing an unequal error protection approach to improve the error resilience tools in baseline JPEG 2000 utilized in wireless streaming over the RTP. Our unequal error protection solution is directly supplied by a mechanism embedded in the JPEG 2000 syntax. At the end, the proposed approach is evaluated subjectively and objectively against existing wireless imaging techniques to demonstrate the achieved quality.

Intellectual Virtue and the Good: A Theory Concerning the Constitutive Value of Intellectual Character
Creators: name: Young, Mark Christopher
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2010
Subjects: subject: Epistemology.
subject: Philosophy.

description: The focus of this thesis is to offer a theory of the constitutive value of intellectual character due to its transformative influence. The specific transformative influence ascribed to intellectual character is that it counteracts self-deceptive mechanisms and disposes agents to obtain true beliefs and to avoid false beliefs. The true beliefs such character reliably produces are accurate representations, and not merely of empirical inputs but also conceptual schemes. Agents do not appear to require such accurate representations to fulfill various desires, or to achieve certain aspects of mental, social and physical well-being as identified by some psychologists. Consequently, agents do not require intellectual character to achieve a variety of things some have identified as good. Nonetheless, a distinction can be made between achieving the good and identifying the good, and it can also be acknowledged that the good is itself a matter of dispute. That is, there are a number of competing notions of the good, which appear to be influenced by various conceptual schemes, and this makes the identification of the good difficult. Intellectual character can fulfill a valuable role in the attempt to settle such disputes through its ability to facilitate true beliefs concerning the good. In fact, intellectual character is necessary to assure agents that their beliefs concerning the good are true due to the imperceptible mechanisms of self-deception. This assurance is itself valuable for any agent who wants to identify the good due to the indispensable role of true belief in attempts to identify the good. Even further, identification of the good is valuable for any agent who wants to achieve the good, since the attempt to identify the good better facilitates achievement of the good. Consequently, the assurance that intellectual character is necessary for is valuable for agents who both want to identify and achieve the good, and for this reason such character is constitutively valuable.

description: Digitalisation is widely recognised as a key enabler for accelerating global wind energy deployment. “Digitalisation” refers to the organisational and industry-wide use of data and digital technologies to improve efficiency, create insights, and develop products and services. Digitalisation not only plays an important role in generating innovation in organisations, but also accelerates the digital transition, where digital technologies streamline processes, enabling faster and more efficient innovation. However, digital technologies can create tension between old values and new ones, making a so-called “digital organisational culture” a prerequisite for the success of these technologies. “Organisational culture” refers to an organisation's beliefs, values and attitudes, and how these influence the behaviour of its employees. “Digital organisational culture” refers to aspects of organisational culture that specifically influence digitalisation, such as instilling a collaborative mindset, a clear orientation towards digital technology changes inside the company's culture, a culture of digital innovation and change and a transparent digital strategy. 

A recent review on the challenges of digitalisation in wind energy showed that organisational culture is one of the three main challenges. It was suggested that aspects of organisational culture such as open feedback culture, positive failure culture, creative culture, and innovation culture can have a large impact on digitalisation, e.g. by affecting how readily data is shared, how digital technologies are tried and tested, or how AI systems and digital twins are designed and used. We are not aware of any studies to understand organisational culture and digitalisation for the wind energy sector, although the above-mentioned review shows that there are some particular challenges in the wind energy sector, such as extreme siloed attitudes, lack of data sharing, lack of data and metadata standards, combined with a high volume and complexity of data coming off wind turbines, which warrant studying in more detail. 

Therefore, this work aims to understand how organisational culture can influence digitalisation in the wind energy sector, and is based on the results of the IEA Wind Task 43 Culture Questionnaire.
On and off the ice: A case study of the involvement of parents in competitive youth hockey
Creators: name: Thompson, Kimberley A
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2010
Subjects: subject: Education, Physical.
subject: Recreation.

description: Initially played for fun, friendship, and an opportunity to exercise, hockey has since become a Canadian tradition rendering it an obsessively competitive culture year-round (Russell, 2(00). Several incidents of inappropriate parental behaviours at minor hockey games have recently received national media attention (Robidoux & Bocksnick, 2010). Hence, it is critical that parents examine their own beliefs and attitudes regarding what they believe youth sports should be all about (Heinzmann, 2002), which highlights the need for research in the area of parental involvement in youth hockey. The purpose of this case study was to investigate the involvement of parents in competitive youth hockey from a symbolic interactionist perspective. More specifically, the purpose was: (a) to explore how parents create their role within the competitive youth hockey culture, and (b) to explore how parents perceive and deal with prevailing issues of aggression within the hockey environment. The study focused on a 'Peewee AA' (11-12 years old) boys' hockey team (parents, players, coaches) registered in a minor hockey association. Within this specific team, three families were also recruited to serve as multiple cases from which in-depth accounts were portrayed. Data were collected throughout a hockey season using: direct observation, participant observation, semi-structured interviews, and in-depth interviews. Findings of this study showed that youth hockey becomes a "lifestyle", whereby the demands were remarkably comparable to that of a professional endeavour, allotting minimal time for "kids to be kids". Parents acknowledged that issues of aggression arise as competition increases, yet they somehow did not recognize themselves as complicit contributors to their existence. Rather, they projected blame on the conflicting yet prevailing beliefs embedded in the culture. While parents expected their children to behave in the manner they deemed "acceptable", much of their own observed behaviours displayed incongruence, creating a sometimes hostile environment among parents, whereby policies were neglected and responsibility for helping ensure a healthy and respectful environment was disregarded. Findings highlight the need for parents, with the support of the larger youth hockey movement, to be held accountable for their behaviours as much as they need to be responsible for sustaining this cultural creation.

Evaluating Machine Learning Methods: scored Receiver Operating Characteristics (sROC) Curves
Creators: name: Klement, William
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2010
Subjects: subject: Computer Science.

description: This thesis addresses evaluation methods used to measure the performance of machine learning algorithms. In supervised learning, algorithms are designed to perform common learning tasks including classification, ranking, scoring, and probability estimation. This work investigates how information, produced by these various learning tasks, can be utilized by the performance evaluation measure. In the literature, researchers recommend evaluating classification and ranking tasks using the Receiver Operating Characteristics (ROC) curve. In a scoring task, the learning model estimates scores, from the training data, and assigns them to the testing data. These scores are used to express class memberships. Sometimes, these scores represent probabilities in which case the Mean Squared Error (Brier Score) is used to measure their quality. However, if these scores are not probabilities, the task is reduced to a ranking or a classification task by ignoring them. The standard ROC curve also eliminates such scores from its analysis. We claim that using non-probabilistic scores as probabilities is often incorrect, and doing it properly would mean imposing additional assumptions on the algorithm or on the data. Ignoring these scores fully, however, is also problematic since, in practice, although they may provide a poor estimate of probabilities, their magnitudes, nonetheless, provide information that can be valuable for performance analysis. The purpose of this dissertation is to propose a novel method that extends the ROC curve to include such scores. We, therefore, call it the scored ROC curve. In particular, we develop a method to construct a scored ROC curve, demonstrate how to reduce it to a standard ROC curve, and illustrate how it can be used to compare learning models. Our experiments demonstrate that the scored ROC curve is capable of measuring similarities as well as differences in the performance of different learning models, and is more sensitive to them than the standard ROC curve. In addition, we illustrate our method's ability to detect changes in data distribution between training and testing.
Asymptotic Results for Some Longitudinal Regression Models

Subjects: subject: Mathematics.

description: The scope of this thesis is to examine asymptotic properties for some longitudinal regression models. These models are often used in biostatistics, econometrics and psychology and involve the collection of several measurements, at different occasions, on the same individuals or clusters. First, we examine the classical regression model for longitudinal data and define the asymptotically optimal estimating equation, with strongly consistent solutions. Then, we consider a simple model with error in covariates, adapted to longitudinal data, obtain estimators of the regression parameters and examine their asymptotic behavior.
title: Inter-Island Variability in Above and Belowground Plant Biomass in Interior Marshes on the Virginia Barrier Islands

description: The Virginia Coast Reserve's Long Term Ecological Research (LTER) site is of great interest because the barrier islands have been migrating, rapidly at times, and are exceptionally dynamic. The barrier islands have tidal saltwater marshes on the lagoon side and freshwater marshes on the island interiors. In these interior marshes on North Hog Island, South Smith Island, and North Parramore Island, salinity and depth to water table were measured to determine if these factors were influencing biomass and biomass allocation patterns in the marsh. Hog Island had the freshest interior marshes (0 and 0.7 ppm), and the most diverse (H'=0.84 and 1.026), but had the least aboveground biomass (36.69 and 161.92 g/m2). Smith and Parramore Islands were more saline (18.6 and 19.8 ppm, respectively), less diverse (H'=0.504 and 0.745), and had higher aboveground biomass (406.86 and 563.32 g/m2). The saltiest marsh, on Parramore Island, had the most aboveground biomass. Belowground biomass was primarily located in fine roots (less than 5 mm diameter). Depth did not have a significant effect on belowground biomass, though this could be due to a small sample size. Roots were found to be related to the vegetation type, and were located primarily in the top 20 cm of the soil, with the exception of Smith Island's marsh. Salinity, depth to water table, and soil nitrogen were all found to be different among marshes. Root: shoot ratios were highest in Hog Island's eastern marsh (0.5), and lowest in Parramore Island's marsh (0.12), and were significantly different. Correlation analysis suggests that salinity, nitrogen, and water table depth may have an influence on biomass and biomass allocation, though r values were not significant due to a low sample size. The results indicate that each island has a unique set of factors influencing the amount of belowground biomass and how biomass is allocated. The depth of the water table may be influencing root allocation in Smith Island's marsh, since its water table is deep, and causing other marshes to have anoxic soils that hinder root development and growth. Diversity and biomass were found to have an inverse relationship, with the most diverse marshes being the least productive. This relationship between diversity and biomass suggests heavy resource competition in these marshes. These barrier islands are different from each other and should be managed individually.

description: In 2005, aid donor and recipient states signed the Paris Declaration on Aid Effectiveness, a major step in creating a global framework based on more equal relations between these countries. It is based on three interrelated core principles: ownership (recipient countries define their own development policies), alignment (donors support these strategies) and harmonization (donors coordinate among themselves). However, more than 15 years later, the implementation of these principles has been globally disappointing. The aid effectiveness agenda and the Global Partnership for effective development cooperation (GPEDC) are facing a legitimacy and relevancy crisis at a time when aid effectiveness is crucial to face increased development and humanitarian challenges in low- and middle- income countries. Faced with this puzzle, this thesis responds to the question: To what extent are the Paris Declaration principles pertinent?

description: Le phénomène migratoire existe depuis la nuit des temps. Même si beaucoup de chercheurs à travers le monde ont fait plusieurs études sur la question de la migration, il reste, certes, un sujet auquel on peut continuer à s'intéresser. Dépendamment de l'auteur(e) et de ce qu'il/elle recherche, la migration peut-être abordée sous différents angles. Dans le cadre de ce travail, nous avons étudié les immigrant(e)s haïtien(ne)s hautement qualifié(e)s et leur insertion sur te caste du travail canadien. D'après le constat que nous avons fait, s'il existe plusieurs études sur cette population immigrante; nous n'avons, cependant, rien trouvé en ce qui concerne ce groupe spécifique. C'est en ce sens que nous avons jugé nécessaire de considérer directement ce groupe d'immigrant(e)s haïtien(ne)s entre au Canada entre 1990 et 2005. La situation de sous-emploi que présentent tes statistiques canadiennes concernant les immigrante haïtien(ne)s est très préoccupante. Elle nous a incité à chercher tout d'abord à savoir si ce groupe qui a constitué notre échantillon fait parti de ceux et celles qui confrontent ce problème de sous-emploi. Notre tâche était aussi d'essayer de comprendre, dans la mesure où c'était le cas, les causes de ce problème. Nous avons, en fait, abouti à la conclusion qu'il existe une disparité entre les immigrant(e)s hautement qualifié(e)s qui sont arrivé(e)s au Canada à partir de la politique d'immigration canadienne pour les immigrant(e)s qualifié(e)s. D'une part, ils/elles sont satisfait(e)s de leur parcours au Canada; ils/elles ont un bon emploi et ont atteint en quelque sorte leurs objectifs. D'autre part, ce sont des gens qui ne sont pas tout à fait satisfaits de leur situation au Canada. Les affaires n'ont pas été selon leurs attentes; ils/elles ont fait des études comme les autres; cependant, ils/elles n'ont même pas pu décrocher un emploi à temps plein. Donc, tout le travail consistait à déterminer les causes du problème de sous-emploi où même de non emploi des gens qualifiés et prêts à travailler. C'est ce qui a été développé tout au long de notre analyse.

description: Compared to quantitative data, qualitative data are shared with repositories and other researchers much less frequently due to additional practical and ethical considerations that must be made before sharing. As new data sharing requirements are implemented by various funders, understanding and addressing the barriers to sharing qualitative data are increasingly important. This paper describes a project that attempts to do just that. In collaboration with other institutional partners, we have developed a process that helps overcome some barriers to sharing qualitative health data, using technical and non-technical assistance in the data preparation process. In addition to describing the process we developed in this project, we summarize the lessons learned about emerging best practices in sharing qualitative health data and offer recommendations for improving qualitative data sharing. These recommendations can be implemented by individual researchers, institutions, and data repositories to ensure FAIR access to qualitative health data.
Legal Necro-politics: Bhutto's Hanging and the Moral Collapse of Capital Punishment

description: Capital Punishment has not only been in effect since the formation of the Islamic Republic of Pakistan, but has also been, on multiple prominent occasions, abused by certain powerful entities of the State with ulterior motives, of which the most notable landmark was The Bhutto case 1979. The lack of Rule of Law in Pakistan is a major concern which is further fueled and aggravated by the distressing misuse of power; in such a State, the mere existence of capital punishment warrants an immense level of endangerment to the life of any person, party or group of individuals who attempt to bring about change by raising a voice or by forming or displaying resistance against a tyranny ridden regime, that may seem “political” at the surface level but musn’t be took at par value, because in actuality it is one that is puppetered at the hands of the establishment, alongside their associated agencies, making it out to be nothing short of unequivocally dictatorial in nature. This case study aims to highlight the benefits of abolishing capital punishment in Pakistan and the effects it shall have on such a country, by putting the Bhutto Case under microscopic observation. Furthermore, in a civilised society, laws evolve, as do the punishments, leading to being made progressive and humane with the passage of time. Many advanced societies of the world, such as that of England and Wales, have abolished the use of capital punishment through law reforms, preventing its misuse. In turn, they devised effective remedies by providing alternative punishments that holistically yield a more fruitful outcome for society as a whole by focusing more on reformation through penalisation rather than blatantly putting an end to the life of the convicted individual. However, quite the opposite trend has been observed in the laws of the Islamic Republic of Pakistan: initially, the capital penalty was only to be used as a sentence for treasonous acts against the State as well as the offence of murder, whereas, in present day, this number has risen from a mere 2 to 33 crimes that are punishable by death, hence having a regressive effect in the evolution of the State’s law. This study further aims toshow how abolishing capital punishment can be in the best interest of the State by viewing the improvement this reform has had in countries where it was implemented, focusing primarily on the UK.
Interface Shear Behavior of Sensitive Marine Clays --Leda Clay

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2010
Subjects: subject: Engineering, Civil.

description: Leda clay, which is a type of sensitive marine clay in Canada, is a hazardous soil that could undergo sudden collapse and flow upon wetting and remolding. This type of soil causes many landslide disasters and foundation damage. The existence of Leda clay at or near the proximities of developed cities makes it challenging for infrastructure expansion, and therefore, challenging for geotechnical engineers. At the location where this sensitive marine clay exists, many foundation designers have adopted the use of deep foundations, such as pile foundations to support heavy structures. The shear behavior and strength parameters at the interface between the (friction) pile and soil are key design parameters. A sufficient knowledge of these interface shear behaviors and strength parameters is also essential for the safe and cost-effective design of several other geotechnical structures (e.g., retaining walls, reinforced soils, and buried structures). However, no studies have yet been implemented on the interface shear behavior between Leda clay and structural material. There is therefore, a need to generate more knowledge about the interface shear behavior of Leda clay. This thesis deals with an experimental study of the shear behavior at the interface between Leda clay and structural material, such as steel and concrete. The effects of several factors, such as surface roughness of the construction material, Leda clay's overconsolidation ratio (OCR), saturation degree, density, and salt content on interface shear behavior are also investigated. Laboratory tests have been carried out by using an automatic direct shear machine connected to a linear variable differential transformer (LVDT), loading cell and a data logging system. The results of the interface shear tests show that under consolidated drained (CD) and saturated conditions, the interface friction angle increases with an increase in the clay's OCR. The results also indicate that increasing the salinity of Leda clay's pore water enhances its frictional resistance at the interface. Furthermore, the results reveal that Leda clay with a higher dry density shows higher interface shear resistance. On the other hand, the results also show that the interface shear resistance decreases as the degree of saturation of the Leda clay increases.
Thorium-230 normalized particle flux and sediment focusing in the Panama Basin region during the last 30,000 years

description: Application of the 230Th normalization method to estimate sediment burial fluxes in six cores from the eastern equatorial Pacific (EEP) reveals that bulk sediment and organic carbon fluxes display a coherent regional pattern during the Holocene that is consistent with modern oceanographic conditions, in contrast with estimates of bulk mass accumulation rates (MARs) derived from core chronologies. Two nearby sites (less than 10 km apart), which have different MARs, show nearly identical 230Th-normalized bulk fluxes. Focusing factors derived from the 230Th data at the foot of the Carnegie Ridge in the Panama Basin are >2 in the Holocene, implying that lateral sediment addition is significant in this part of the basin. New geochemical data and existing literature provide evidence for a hydrothermal source of sediment in the southern part of the Panama Basin and for downslope transport from the top of the Carnegie Ridge. The compilation of core records suggests that sediment focusing is spatially and temporally variable in the EEP. During oxygen isotope stage 2 (OIS 2, from 13–27 ka BP), focusing appears even higher compared to the Holocene at most sites, similar to earlier findings in the eastern and central equatorial Pacific. The magnitude of the glacial increase in focusing factors, however, is strongly dependent on the accuracy of age models. We offer two possible explanations for the increase in glacial focusing compared to the Holocene. The first one is that the apparent increase in lateral sediment redistribution is partly or even largely an artifact of insufficient age control in the EEP, while the second explanation, which assumes that the observed increase is real, involves enhanced deep sea tidal current flow during periods of low sea level stand.

Tests non-parametriques de tendance sur les proportions

Subjects: subject: Mathematics.

description: The problem of testing for a monotone trend in proportions has been frequently disccussed in the literature and in various applications. The popular Cochran-Armitage test has received much attention in the past. It is based on measuring the correlation between the proportions of observed success at any time point with a collection of monotone constants which mimic the time trend. Unfortunately the Cochran-Armitage is sensitive to the choice of these constants as well as to the sample sizes. In this thesis, we propose two nonparametric tests based on the ranks of the data. These tests rely on the notion of compatibility introduced by Alvo and Cabilio and required the specification of a distance function between permutations. We derive the statistics tests which correspond to the Spearman, Kendall and Hamming distances. It is shown that the Spearman and Kendall distances lead to the same test statistic. We show that the asymptotic null distributions of the Spearman and Hamming based test statistics are both normal. We study the non-null distributions through simulation under various scenarios. We conclude that the Spearman statistic has generally higher power and is therefore the recommended test. We also note that the modified Hamming based statistic yield a higher power than the Hamming statistic. Furthermore, in some cases the power of the modified Hamming statistic is very close to the power of the Spearman statistic.

description: Shadowbanning is a unique content moderation strategy receiving recent media attention for the ways it impacts marginalized social media users and communities. Social media companies often deny this content moderation practice despite user experiences online. In this paper, we use qualitative surveys and interviews to understand how marginalized social media users make sense of shadowbanning, develop folk theories about shadowbanning, and attempt to prove its occurrence. We find that marginalized social media users collaboratively develop and test algorithmic folk theories to make sense of their unclear experiences with shadowbanning. Participants reported direct consequences of shadowbanning, including frustration, decreased engagement, the inability to post specific content, and potential financial implications. They reported holding negative perceptions of platforms where they experienced shadowbanning, sometimes attributing their shadowbans to platforms’ deliberate suppression of marginalized users’ content. Some marginalized social media users acted on their theories by adapting their social media behavior to avoid potential shadowbans. We contribute collaborative algorithm investigation: a new concept describing social media users’ strategies of collaboratively developing and testing algorithmic folk theories. Finally, we present design and policy recommendations for addressing shadowbanning and its potential harms.
The functional role of A-type lamin interacting transcription factor (LITF) during skeletal myogenesis

Subjects: subject: Chemistry, Biochemistry.

description: Lamin A/C (LMNA) is ubiquitously expressed in tissues, however specific missense mutations in LMNA result in discrete tissue specific phenotypes such as muscular dystrophy. Using a yeast-two-hybrid assay against a human heart cDNA library, a previously uncharacterized cDNA clone, A-type lamin interacting transcription factor (LITF), was identified. In this thesis the major objective was to determine the function of LITF using C2C12 mouse myoblast cell line. It is hypothesized that LITF is a myogenic factor that is required for myogenesis. Initiation of C2C12 differentiation led to an increase in LITF protein expression by 6 hours and peaking at 18 hours. LITF mediated chromatin immunoprecipitation from C2C12 nuclei with array analysis revealed a significant enrichment (p<0.00001) of promoter regions of developmentally important muscle transcription factors (Six1, Six4, Mef2c, Myogenin) and several other genes implicated in cell cycle and differentiation. Electrophoretic mobility shift assays and co-transactivation experiments revealed that LITF is capable of binding specific DNA sequences and activating transcription. Specific knockdown of LITF in C2C 12 led to a reduction in the expression of Myogenin, MyoD and myosin heavy chain with a significant reduction in myotube formation. Collectively this data suggests that LITF may be a myogenic transcription factor/regulator.

description: A new technique based on the study of the transmitted neutron beam has been developed to study the low-temperature decomposition of austenite in a 0.4 wt.% C–3 wt.% Mn–2 wt.% Si steel. Experiments were conducted in which the neutron beam continuously passed through a specially designed layered sample, the temperature of which could be controlled to allow for a high-temperature austenization treatment followed by accelerated cooling to an isothermal transformation temperature in the range of 275–450 °C. It was possible to measure the volume fraction of the face-centred cubic (fcc) and body-centred cubic (bcc) phases and the carbon concentration of the fcc phase by characterizing the neutron Bragg edges in the transmitted beam. This provides a technique for in situ continuous measurements on the decomposition of austentite. The technique has been validated by comparing the data with other experimental techniques such as dilatometry, quantitative optical metallography and room temperature X-ray diffraction.
Contribution of Track Two Dialogue towards Crisis Prevention

Publisher: name: Asien
Year: 2021

description: The emergence of many think tanks and security-related track two processes in the Asia-Pacific during the last two decades has given rise to speculation about their contribution to the peaceful resolution of disputes and the search for strategies to address the manyfold nontraditional security threats caused by globalization and growing interdependencies. After placing track two dialogues in an basically institutionalist theoretical framework, the article briefly sketches the genesis and development of track two processes since the early 1980s. It then goes on to argue that security-related track two processes represent an innovative response to the region 's security problems and helped to shape an Asian security identity. However, track two dialogues are far from being a panacea. They are plagued by a number of flaws such as their great proximity to government, lack of independence, a traditional, state-centric approach to international relations which is strongly informed by the realist paradigma and a certain degree of exclusiveness.

description: The beneficial effect of long chain omega-3 polyunsaturated fatty acids (LCn-3PUFA) on adiponectin levels has been observed in several animal and human studies after dietary treatment. The purpose of this study was to observe the effect of LCn-3PUFA on the secretion of adiponectin in differentiated human preadipocytes and determine if this effect is under the influence of PPARgamma nuclear receptors. Human adipocytes were exposed to 125muM of DHA or EPA for 24 h. Levels of adiponectin following DHA treatment increased from 0.19+/-0.02 to 0.22+/-0.01 ng/mug, or 13.6% (P<0.05) and from 0.19+/-0.02 to 0.24+/-0.06 ng/mug or 26.2% (P=0.09) after EPA treatments. After the addition of a PPARgamma inhibitor, adiponectin levels dropped of 5.8% and 12.2% for DHA and EPA, respectively. These results confirm the positive effect of LCn-3PUFA on adiponectin levels. These effects seem to be partially mediated by PPARgamma.

description: Noch vor einigen Jahren war es in der auf Vietnam-bezogenen sozialwissenschaftlichen Forschung gebräuchlich, das dortige politische System mit Rigby als das eines "Mono-Organizational Socialism" zu bezeichnen. Spätestens Anfang der 90er-Jahre wurde die Kritik an solchen Konzepten stärker, die den Staat in einer die Gesellschaft vollständig durchdringenden Position sahen und die Entwicklung relativ eigenständiger gesellschaftlicher Organisationen als nahezu unmöglich ansahen.

description: Small mammals were trapped for 23 months on two live trap grids in tidal marshes in Northampton County, on the Eastern Shore of Virginia, to examine ecological relationships between the marsh rice rat (Oryzomys palustris) and the meadow vole (Microtus pennsylvanicus). Population density, survival rates, capture probability, recruitment, residence time, and home range size were calculated for each species. Patterns of reproductive activity and fluctuations in mean weight were also observed.

There were considerable differences in population dynamics between the two sites. At Grid 2, where vegetative cover was more abundant, population densities of rice rats and meadow voles had a seasonal pattern, declining over the winter to low densities in spring, then recovering during the summer and autumn. Densities of the two species were significantly positively correlated, despite having different seasonal reproductive patterns, evidence that there was no competition between the species at Grid 2. At Grid l, where cover was limited, densities of rice rats and meadow voles were both lower and negatively correlated. Capture probabilities, recruitment, home range size, and mean weights were all higher at Grid 2 than Grid 1, further suggesting that Grid 2 is a better habitat for these small mammals.

Politics of Democracy in Malaysia
Creators: name: Heufers, Rainer
Publisher: name: Asien
Year: 2021

description: This article' provides a review of the condition of Malaysian democracy after 20 years of Prime Minister Datuk Seri Dr. Mahathir Mohamad's rule. To this end it looks into issues that were identified as political causes of the Asian crisis in the years after 1997. These are in particular: weak democratic institutions and electoral systems, an executive that dominates parliament, the judiciary, and the media. Considering the Malaysian constitutional background and evolving political trends in recent years of the Mahathir era, the article finds these issues basically unresolved. The country thus seems unprepared for future political challenges and crisis scenarios.

Unholy Coercion: The Complicity of the Serbian Orthodox Church in the Use of Rape as a War Tactic

description: This project investigates the complicity of the Serbian Orthodox Church in the use of sexual violence as a war tactic and means of ethnic cleansing in the Bosnian War. The thesis explores this in three ways: examining religiously imbued incidents of rape by Serbian belligerents, analysing the relationship between Serbian Orthodox authorities to Serbian politics and war criminals, and deconstructing specific Serbian Orthodox theological discourses. A project of this nature relies on two foundational pillars: first, an in-depth exploration of rape (especially in conflict) and second, the interlocking and socially constructed nature of identities, particularly ethnicity, enemies and gender. The analysis relies on United Nations reports, transcripts of the International Criminal Tribunal for the former Yugoslavia, media reports and secondary sources, all of which illustrate the often subtle and discursive relationship between the Serbian Orthodox Church and the systematic rape of Bosniak women.
Christentum und Buddhismus als Antagonisten?

description: Neben der ethnischen Abgrenzung der Sgaw-Karen in Nordthailand verlaufen auch intraethnische Grenzlinien, die sich an den Religionen Christentum und Buddhismus orientieren. Die christliche Identität verstärkt eine Abgrenzung gegenüber der dominanten Thai-Gesellschaft, der Buddhismus bewirkt eher das Gegenteil. Im Folgenden wird dargelegt, wie sich die Religionen auf die ethnische Identität auswirken und wie sich Christentum und Buddhismus gegenüber traditionellen religiösen Inhalten darstellen. Es geht auch um die Frage, ob die Annahme des Christentums eine Veränderung des traditionellen ökologisch orientierten Weltbildes der Karen bewirkt. Darüber hinaus werden die Missionstätigkeiten beider Glaubensrichtungen kurz skizziert.

description: In this study a new method is introduced to produce bimodal grain structures in low carbon steels. This method is based on cold rolling of dual phase structures and appropriate annealing treatments. The difference in the recrystallization behaviour of ferrite and martensite yields a heterogeneous microstructure with a distribution of coarse and fine grains. These types of microstructures are of interest for optimizing the balance of strength and uniform elongation in ultra-fine grained low carbon steels.

description: Acetylcholinesterase (AChE) activity in the neonatal rat brain was determined by histochemical localization and quantitative biochemical analysis. AChE-positive perikarya were concentrated in the neostriatum, globus pallidus, medial habenular nucleus, amygdaloid complex, various hypothalamic nuclei, gigantocellular and paragigantocellular reticular nuclei, raphe nuclei, locus coeruleus, and motor nuclei of cranial nerves III-VII and IX-XII. Some areas stained differently or not at all when compared with the adult rat brain. The effects of prenatal ethanol exposure on regional AChE activity were assessed by comparing enzyme levels in offspring exposed via maternal consumption of a liquid diet containing 35 percent ethanol derived calories. This treatment resulted in a significant increase in AChE activity in the hippocampus and the hypothalamus as measured by biochemical assay. These differences were not observed by histochemistry, probably due to a lack of technique sensitivity for demonstrating small changes in AChE levels.
