Zvklus (1959) by Karlheinz Stockhausen and Duettino Concertante (1966) by Ingolf Dahl represent two of the most significant percussion compositions that present the percussionist as soloist. The performer of these works, either unaccompanied or accompanied by a non-percussion instrument, is featured as executant, interpreter, and improvisor. They are regarded as classics in the medium of multiple percussion because of their frequency of performance and their profound effect on notation, musical composition, and the technical expectations of the percussionist. This paper examines these compositions and their historical significance to both percussion literature and the percussionist. Each of these compositions is analzyed by examining instrumentation, compositional procedures, and performance problems. Finally, the notational procedures and role of the performer in these compositions are compared. A discussion of the development of the percussion batterie, percussion ensemble, and the important early solo multiple percussion compositions provides historical perspective for these compositions. This perspective is enhanced by consideration of biography, influences, and stylistic development of each composer.

High salt intake contributes to the development of hypertension in salt-sensitive humans and animals and the mechanistic causes are poorly understood. In Dahl salt-sensitive (S) but not salt-resistant (R) rats, high salt diet increases cerebrospinal fluid (CSF) [Na+] and activates an aldosterone-mineralocorticoid receptor-epithelial sodium channel-endogenous ouabain (MR-ENaC-EO) neuromodulatory pathway in the brain that enhances the activity of sympatho-excitatory angiotensinergic and glutamatergic pathways, leading to an increase in sympathetic nerve activity (SNA) and blood pressure (BP). We hypothesize that high salt diet in Dahl S rats enhances Ang II release in the paraventricular nucleus (PVN), causing a decrease in local nitric oxide (NO) action and an increase in local glutamate release thereby elevating SNA, BP and heart rate (HR). The present study evaluated the effects of agonists or blockers of MR, ENaC, EO, nitric oxide synthase (NOS) or glutamate and AT1-receptors on the BP and HR responses to acute infusions of Na+ rich aCSF, intracerebroventricularly (icv), or in the PVN of Dahl S, R or Wistar rats or to high salt diet in Dahl S and R rats. In Wistar rats, aldosterone in the PVN enhanced the BP and HR responses to infusion of Na+ rich aCSF in the PVN, but not in the CSF, and only the enhancement was prevented by blockers of MR, ENaC and EO in the PVN. AT1-receptor blockers in the PVN fully blocked the enhancement by aldosterone and the responses to infusion of Na+ rich aCSF icv, or in the PVN. Na+ rich aCSF in the PVN caused larger increases in BP and HR in Dahl S vs. R rats and the responses to Na+ were fully blocked by an AT1-receptor blocker in the PVN. BP and HR responses to a NOS blocker in the PVN were the same, but L-NAME enhanced Na+ effects more in Dahl R than S rats. High salt diet attenuated increases in BP from L-NAME in the PVN of Dahl S but not R rats. AT1 and glutamate receptor blockers candesartan and kynurenate in the PVN decreased BP in Dahl S but not R rats on high salt diet. At the peak BP response to candesartan, kynurenate in the PVN further decreased BP whereas candesartan did not further decrease BP at the peak BP response to kynurenate. Our findings indicate that both an acute increase in CSF [Na+] and high salt intake in Dahl S rats increases AT1-receptor activation and decreases NO action in the PVN thereby contributing to the pressor responses to Na+ and presumably, to dietary salt-induced hypertension. The increased BP response to AT1-receptor activation in the PVN of Dahl S is mediated by enhanced local glutamate receptor activation. An MR-ENaC-EO pathway in the PVN can be functionally active and further studies need to assess its role in Dahl S rats on high salt intake.

Master of Music / School of Music, Theatre, and Dance / Anna Marie Wytko / Ingolf Dahl’s Concerto for Alto Saxophone and Wind Orchestra is considered a master concert work in saxophone literature. The work was written for saxophone pioneer Sigurd Rascher who was active in commissioning new works for the instrument. Piet Swerts’ Klonos, composed over 40 years after Dahl’s Concerto, is a much newer composition. The work has gained national recognition as a popular competition piece and is a synthesis of new and old compositional styles. These two works strongly showcase the flexibility and virtuosity capable of the skilled saxophonist. This master’s report, presented as extended program notes, includes biographical information about the composers, a historical and stylistic overview of the selected compositions, and a harmonic and formal analysis of the music with respect to performance considerations.

<p>ABSTRACT</p><p>Essay in Political Science, Advanced Continuation Course, 61-80 credits, by Jonas Nilsson</p><p>”The democratic islamist? - a study of three islamist movements and their potential role in a</p><p>democratization process”</p><p>Supervisor: Jonas Linde</p><p>The purpose of this work has been to explain to what extent islamist movements can be said to be</p><p>bearers of democratic values and if they have a role to play in future democratization processes. The</p><p>purpose of this work is also to examine the democratic views of the different islamist movements and</p><p>to compare them with each other in an effort to find a specific islamist definition of democracy.</p><p>The essay is a qualitative analysis of the Muslim Brotherhood in Egypt, Front Islamique du Salut in</p><p>Algeria and Hezbollah in Lebanon. The analytical framework is based on the political institutions</p><p>included in Robert A. Dahl polyarchial democracy. The institutions provided by the polyarchial</p><p>model is used to define the islamist movements stand on democracy which is defined by three different</p><p>standpoints. The movements can either accept, decline or modify the various institutions and the</p><p>results from the analysis helps us to evaluate the future role of islamist movements in the</p><p>democratization process. The results also provides the opportunity to define a version of democracy</p><p>specific for the islamist movements. The conclusion I have made is that the islamist movements</p><p>included in the study have a part to play in a future democratization process. They have shown that</p><p>their commitment to the democratic ideals defined by Dahl is quite extensive and that they as</p><p>separate movements have developed a more advanced view of the relationship between islam and</p><p>democracy as a social order. Though democratic at first glance there are signs that the islamists</p><p>standpoint on democracy comes with certain reservations. The most significant of these</p><p>reservarvations is the islamists regard of islam as an overarching ideology and the subordinate role</p><p>of man made political systems such as democracy. However, the islamists have found ways to handle</p><p>this problem and points out the inherent democratic values in islam and thereby tries to circumvent</p><p>the problematic relationship between democracy and religion. The study also concludes that we can</p><p>define the islamist version of democracy as a specific form of democracy, a value-based participatory</p><p>democracy. This conclusion is based on the islamist emphasis on the importance of ethics, decency</p><p>and virtue in a society, at the same time as they also emphasize the need for legitimacy provided by</p><p>the people through free, fair and frequent elections.</p>

High salt intake contributes to the development of hypertension in salt-sensitive humans and animals and the mechanistic causes are poorly understood. In Dahl salt-sensitive (S) but not salt-resistant (R) rats, high salt diet increases cerebrospinal fluid (CSF) [Na+] and activates an aldosterone-mineralocorticoid receptor-epithelial sodium channel-endogenous ouabain (MR-ENaC-EO) neuromodulatory pathway in the brain that enhances the activity of sympatho-excitatory angiotensinergic and glutamatergic pathways, leading to an increase in sympathetic nerve activity (SNA) and blood pressure (BP). We hypothesize that high salt diet in Dahl S rats enhances Ang II release in the paraventricular nucleus (PVN), causing a decrease in local nitric oxide (NO) action and an increase in local glutamate release thereby elevating SNA, BP and heart rate (HR). The present study evaluated the effects of agonists or blockers of MR, ENaC, EO, nitric oxide synthase (NOS) or glutamate and AT1-receptors on the BP and HR responses to acute infusions of Na+ rich aCSF, intracerebroventricularly (icv), or in the PVN of Dahl S, R or Wistar rats or to high salt diet in Dahl S and R rats. In Wistar rats, aldosterone in the PVN enhanced the BP and HR responses to infusion of Na+ rich aCSF in the PVN, but not in the CSF, and only the enhancement was prevented by blockers of MR, ENaC and EO in the PVN. AT1-receptor blockers in the PVN fully blocked the enhancement by aldosterone and the responses to infusion of Na+ rich aCSF icv, or in the PVN. Na+ rich aCSF in the PVN caused larger increases in BP and HR in Dahl S vs. R rats and the responses to Na+ were fully blocked by an AT1-receptor blocker in the PVN. BP and HR responses to a NOS blocker in the PVN were the same, but L-NAME enhanced Na+ effects more in Dahl R than S rats. High salt diet attenuated increases in BP from L-NAME in the PVN of Dahl S but not R rats. AT1 and glutamate receptor blockers candesartan and kynurenate in the PVN decreased BP in Dahl S but not R rats on high salt diet. At the peak BP response to candesartan, kynurenate in the PVN further decreased BP whereas candesartan did not further decrease BP at the peak BP response to kynurenate. Our findings indicate that both an acute increase in CSF [Na+] and high salt intake in Dahl S rats increases AT1-receptor activation and decreases NO action in the PVN thereby contributing to the pressor responses to Na+ and presumably, to dietary salt-induced hypertension. The increased BP response to AT1-receptor activation in the PVN of Dahl S is mediated by enhanced local glutamate receptor activation. An MR-ENaC-EO pathway in the PVN can be functionally active and further studies need to assess its role in Dahl S rats on high salt intake.

<p>The purpose of this thesis is to study the level of democracy within the European Union (EU). To do so the following issues were examined: How the EU works and the efforts it has made to improve levels of democracy; and the degree to which the EU fulfils the criteria set by Robert Dahl in his theory of polyarchy.</p><p>The study is based on a qualitative text analysis. The focus of the analysis is documents released by the EU that can be connected to democracy, and human and fundamental rights. The theory of polyarchy proposed by Robert Dahl and Joseph Schumpeter’s theory of democracy are the principal theories applied. The thesis also includes theories about democracy within the EU prior to this study.</p><p>The result and conclusion after studying the documents in the light of the theories of Dahl and Schumpeter suggest that the EU could be more democratic than it is at present. The movement towards becoming more democratic is in progress but needs more time. The fundamental criterion, i.e. that citizens should to be able to choose the holders of a particular position, is weak in the EU because there are only general elections to the European Parliament, which is just one of the three main institutions.</p>

For the last decades, Sweden has transformed from a state with strong elements of corporatism, to a governance of pluralistic character. This development has opened up to a new form of participation – lobbyism – which since has spread and commercialized. Because of this, a report on the state of Swedish democracy – Demokratiutredningen – was issued to examine the phenomenon of lobbyism as it was feared to challenge the functioning of a representative democracy. The report issued a warning of the negative impact on transparency and political equality a professionalization of lobbying could have. Even some forms of regulation were thought to have a negative impact on the political equality. Since the report was released in 2000, nine bills regarding lobbyism have been presented to the Swedish parliament, but no regulation has yet been implemented. The report identified problems regarding transparency and political equality with both regulated and unregulated lobbying. The aim of this thesis is to examine how the parliamentary bills handle the democratic problems voiced by the report. The bills are analyzed with the ideal types of “transparency” and “political equality”, based on Robert Dahl’s ideal of democracy. The study found that the problem of transparency was of a high priority in the bills, while the problem of political equality was hardly addressed. Three of the bills actually ignored the warning issued by the report, where a regulation in the form of registration was thought to have a negative impact on political equality. The fact that the bills hardly addressed the problem of political equality, and in some cases even worsened it, represents a democratic deficit in the regulation debate. / De senaste decennierna har Sverige förvandlats från en stat med starka inslag av korporativism, till ett styrelseskick med pluralistisk prägel. Utvecklingen har öppnat upp för en ny deltagandeform, lobbyism, som sedan dess brett ut sig och kommersialiserats. Med anledning av detta tillkallade regeringen Demokratiutredningen för att analysera lobbningen då den ansågs utmana den representativa demokratins funktionssätt. Demokratiutredningen varnade för att professionaliseringen av lobbying kunde påverka öppenheten och den politiska jämlikheten negativt. Även vissa regleringar ansågs kunna försämra den politiska jämlikheten. Sedan Demokratiutredningen överlämnade sitt slutbetänkande år 2000 har nio motioner gällande lobbyism lagts fram i Sveriges riksdag utan att resultera i en reglering. Demokratiutredningen identifierade demokratiproblem med både öppenhet och politisk jämlikhet i oreglerad, såväl som reglerad, lobbyism. Uppsatsen studerade hur motionerna i ärendet hanterat de demokratiproblem som utredningen framhävde. Studien genomfördes med idealtyper som analysverktyg. Idealtyperna, ”öppenhet” och ”politisk jämlikhet”, byggdes upp med hjälp av Robert Dahls demokratiideal. Studien fann att problemet med öppenhet uppmärksammades i hög grad av motionerna, medan politisk jämlikhet knappt hanterades alls. Tre av motionerna ignorerade till och med den varning som Demokratiutredningen utfärdade, där en reglering i form av registrering skulle påverka den politiska jämlikheten negativt. Att motionerna inte hanterar problemet med politisk jämlikhet, och i flera fall även förvärrar den, innebär ett påtagligt demokratiskt underskott i regleringsdebatten.
