A Closer Look at Fedora's Ingest Performance

4th International Conference on Open RepositoriesThis presentation was part of the session : Fedora User Group PresentationsDate: 2009-05-21 10:30 AM – 12:00 PMIt is of paramount importance for large-scale applications that Fedora can handle huge amounts of data efficiently. While Fedora is generally known to be stable and reliable, there appears to be a lack of data and experience regarding large-scale installations and the performance implications thereof. FIZ Karlsruhe is currently working on several projects with large-scale Fedora repositories holding several million complex objects. We conducted extensive performance and scalability tests with the current Fedora software (mostly version 3.0), focusing on ingest operations. Our goal was to prove that Fedora actually scales well enough for our use cases. Our test runs provided us with data which helped us identifying limits and constraints, and devising some optimization recommendations

POŁUDNIOWOKOREAŃSCY LIDERZY W POLITYCE DEMOKRATYZACJI

This article aims to show the process of formation and operation (functioning) of the changing political system of South Korea. It is undertaken for the analysis of the process of the collapse of the former authoritarian political system and formation of South Korean democracy. Indicated in this article are the roles and participation of political leaders (Chun Doo Hwan, Roh Tae Woo, Kim Young Sam, and Kim Dae Jung) in the process of intense political change that took place in South Korea from the 1980s to the late twentieth century.During the authoritarian regimes of South Korea, the nation recorded spectacular economic development, but without political development. Political leadership in the democratization of the country was still authoritarian. Core values and attitudes of politicians pointed to the presence of the cultural heritage of Confucianism in politics.본고의 목적은 한국의 변화하는 정치 체제의 형성과 운영(기능)과정을 보여주는 것이다. 이 연구는 전독재정치체제가 붕괴되고 남한민주주의가 형성되는 과정을 분석하기 위해 착수되었다. 본 연구서는 1980년대부터 20세기말까지 한국에서 일어난 치열한 정치적 변화 과정에서 정치지도자 (전두환, 노태우, 김영삼, 김대중)의 역할과 참여가 검토된다. 독재정권시대에 한국은 놀라운 경제발전을 기록했지만 정치발전은 없었다. 국가의 민주화에서 정치적 리더십은 여전히 독재적이었다. 정치가의 핵심 가치와 태도는 정치에서 유교의 문화유산이 존재함을 지적했다.Artykuł ma na celu ukazanie procesu kształtowania się i funkcjonowania zmieniającego się systemu politycznego w Korei Południowej. Podejmowana zostaje analiza procesu upadku autorytarnego systemu politycznego i formowanie się południowokoreańskiej demokracji. Wskazano na rolę i uczestnictwo liderów politycznych (Chun Doo Hwan, Roh Tae Woo, Kim Young Sam, Kim Dae Jung) w procesie intensywnych zmian politycznych, które miały miejsce w Korei Południowej pod koniec lat 80 XX wieku.W okresie autorytarnych rządów Korea Południowa odnotowała spektakularny rozwój gospodarczy, jednak nie towarzyszył temu rozwój polityczny. Przywództwo polityczne w demokratyzującym się państwie nadal pozostawało autorytarne. Ponadto wyznawane wartości i postawy polityków wskazywały na obecność kulturowego dziedzictwa konfucjanizmu w polityce

Full Nash Implementation of Neutral Social Functions

This paper characterizes neutral social functions that are fully implementable. A necessary condition for full implementation under either the Nash equilibrium concept or the strong Nash equilibrium concept is that the neutral social function being implemented be monotonic and simple. If a neutral monotonic social function is simple and the set of winning coalitions is nondictatorial then the social function is fully implementable by a set of Nash equilibria. For finite alternative sets a neutral monotonic social function will be fully implementable by a set of strong Nash equilibria if and only if it is simple and dictatorial

The Repechy Guest-House

Bakalářská práce vychází z ateliérového projektu vytvořeného v letním semestru 3. ročníku bakalářského studia. Úkolem byla obnova a dostavba selského stavení na ubytovací zařízení rozšířené o další služby. Objekt selského stavení se nachází v malé obci Repechy nedaleko města Prostějov a je doplněn o další dva nevyužívané objekty. Ve druhé polovině 20. století bylo selské stavení obdélníkového tvaru s dvorem zastřešeno, vnitřní stěny byly částečně vybourány a vnitřní prostor byl využit pro ustájení dobytka. To mělo na současný stav objektu velký dopad. Agresivní prostředí a zvýšená vlhkost, na kterou konstrukce nebyly navrženy, výrazně urychlily proces degradace objektu. Později byl provoz ustájení dobytka přemístěn a původní selské stavení od té doby chátrá. V současné době se pozemek i objekt nachází v zanedbaném stavu. Většina konstrukcí je poničených a dále nepoužitelných. Za záchranu stojí severní trakt, u kterého se dochovaly cenné historické šambrány a další plastická výzdoba. Okolí objektu je zarostlé náletovou zelení. Cílem bylo zachovat a přiznat původní hodnotné části a najít pro ně vhodné využití za stanovených podmínek. Návrh počítá s odstraněním tří stran obdélníkového stavení a zachováním severního traktu ve formě torza. Přístavba vychází z původního stavení. Rozšiřuje původní hranici zastavěné plochy, čímž využívá stávající struktury a vytváří tak první objem, který symbolizuje tradiční statické tvarosloví. Pootočený duplikát prvního objemu potom charakterizuje moderní a dynamický přístup v architektuře. Výsledný návrh přístavby vzniká syntézou obou objemů jako důkaz koexistence tradičního a moderního přístupu. Navržená přístavba je v celé ploše jednopodlažní, lokálně suterénní i dvoupodlažní. Přístavba je zároveň charakteristická použitím cortenové provětrávané fasády, která přesahuje atiky do různých výšek a vytváří tak lomenou strukturu, která může být z různých úhlů vnímána buď jako idealizované seskupení štítů střech tradiční zástavby nebo jBachelor’s thesis is based on a studio project created in the summer term of the third year of the undergraduate studies. The task was the renewal and the extension of the farmhouse for an accommodation facility and other services. The farmhouse is situated in a small village Repechy near the town of Prostejov and is complemented by two other unused buildings. In the second half of the 20th century, rectangular shaped farmhouse with a yard was roofed, interior walls were partially demolished and interior space was used for keeping the cattle. It had a big impact for the current condition of the object. Aggressive environment and high humidity, for which structures were not designed, significantly accelerate the degradation process. Later, the cattle was moved away and the original farmhouse is deteriorating until these days. Currently, the object and its surroundings are in a bad condition. Most of the constructions are damaged and it is not possible to use them anymore. Northern tract is the only part worth protection. There are preserved precious historical chambranles and other plastic decoration. Surroundings is overgrown with wild vegetation. The aim was to preserve and bring out valuable parts of the original object and find them appropriate use under specified conditions. The proposal deals with the removal of three sides of a rectangular farmhouse and preserving the northern tract in the form of a torso. Extension is based on the original farmhouse. Extends the original built up area boundary to use existing structure and creates the first volume, which symbolizes the traditional static form. Rotated duplicate of the first volume then characterized a modern and dynamic attitude in architecture. The final design of an extension is created by synthesis of both volumes as an evidence of the coexistence of a traditional and a modern form. Designed extension has one floor, locally basement and second floor. The extension is also characterized by the use

Choosing a Tax Treatment for New Financial Products

Two desirable properties for a tax system that must specify tax treatments for new financial instruments are consistency and universality. A tax system is universal if the system can designate a tax treatment for any cash flow pattern. Consistency requires that the tax treatment for each cash flow pattern be unique. A third property, linearity, holds if dividing the cash flow into different combinations of securities will not affect the tax treatment. One way to achieve consistency and universality is to construct a tax system with a single systematic pattern of taxation, such as cash flow taxation or accretion taxation. But this extreme degree of homogeneity is not necessary. Consistent and universal tax systems can harbor radically different treatments for different types of transactions. "Bifurcation approaches" divide a new financial instrument into certain prototype transactions with known tax treatments. The tax treatment for the new instrument is the sum of the tax treatments of the prototypes that sum up to the instrument. "Integration approaches" use rules that tax aggregates of instruments within the taxpayer's portfolio. Bifurcation methods have a natural connection to linearity. These methods will not achieve consistency and universality in a nonlinear setting unless they are accompanied by elements of an integration approach. All universal and linear tax systems can be generated by "the spanning method," a specific kind of bifurcation. Spanning method approaches are only a subclass of a broader set of integration approaches that achieve consistency and universality. In evaluating integration approaches, a key property is continuity, the requirement that tax treatments do not jump in response to small changes in any given portfolio. Continuity is a generalization of consistency. The existence of jumps leads to the possibility of serious tax manipulation of the same sort that would arise from inconsistencies. The current U.S. tax system includes some direct inconsistencies. That is, the same transaction can be packaged different ways to achieve different tax results. These inconsistencies can only be eliminated by fundamental reform. Even the most powerful integration approaches cannot address the problem of direct inconsistencies. This fact raises difficulties for authorities such as the Treasury Department and the courts who have only low level reform at their disposal. In promulgating regulations or deciding cases that involve new financial instruments, these authorities must choose rules using a second best approach. Loose ends in the form of inconsistencies or lack of universality are inevitable

American Feminism – the Third Wave. The Change and Continuation

The history of American women fighting for equal rights dates back to the 18th century, when in Boston, in 1770, they voiced the demand that the status of women be changed. Abigail Adams, Sarah Grimke, Angelina Grimke and Frances Wright are considered to have pioneered American feminism. An organized suffrage movement is assumed to have originated at the convention Elizabeth Stanton organized in Seneca Falls in 1848. This convention passed a Declaration of Sentiments, which criticized the American Declaration of Independence as it excluded women. The most prominent success achieved in this period was the US Congress passing the Nineteenth Amendment to the Constitution granting women the right to vote. The 1960s saw the second wave of feminism, resulting from disappointment with the hitherto promotion of equality. The second-wave feminists claimed that the legal reforms did not provide women with the changes they expected. As feminists voiced the need to feminize the world, they struggled for social customs to change and gender stereotypes to be abandoned. They criticized the patriarchal model of American society, blaming this model for reducing the social role of women to that of a mother, wife and housewife. They pointed to patriarchal ideology, rather than nature, as the source of the inequality of sexes. The leading representatives of the second wave of feminism were Betty Friedan (who founded the National Organization for Women), Kate Millet (who wrote Sexual Politics), and Shulamith Firestone (the author of The Dialectic of Sex: The Case for Feminist Revolution). The 1990s came to be called the third wave of feminism, characterized by multiple cultures, ethnic identities, races and religions, thereby becoming a heterogenic movement. The third-wave feminists, Rebecca Walker and Bell Hooks, represented groups of women who had formerly been denied the right to join the movement, for example due to racial discrimination. They believed that there was not one ‘common interest of all women’ but called for leaving no group out in the fight for the equality of women’s rights. They asked that the process of women’s emancipation that began with the first wave embrace and approve of the diversity of the multiethnic American society.The history of American women fighting for equal rights dates back to the 18th century, when in Boston, in 1770, they voiced the demand that the status of women be changed.

W CIENIU I FORMIE: KONFLIKT DWUZNAKÓW W KOREAŃSKIM NACJONALIZMIE

This paper is an examination of the many points of intersection between Korean nationalism in both Koreas, and Chinese characters (Hanja), as well as a contextualization of the historical and, at times, antithetical relationship or binary consisting of Hanja and Han’gŭl (Chosŏn’gŭl). Emerging from liberation the two Korean states over the next several decades would “engage” Hanja with diverse and fluctuating positions and approaches at different times. These responses have ranged from the abolition of Hanja or the enforcement of Han’gŭl (Chosŏn’gŭl) exclusivity, to the re-establishment and strengthening of Hanja education. Koreans for over a century have responded to “issues of script” based on socially-created narratives. This phenomenon can be viewed through constructivist paradigms, or can be interpreted as implemented pragmatic policies exemplifying instrumentalist nationalism. This paper’s assertion is that Korea’s vacillating response regarding Korean nationalism’s digraphic conflict is eloquent of the complex confluences that formed Korean ethnic nationalism, and therefore, Korean national identity.본 논문은 남북한의 민족주의와 한자 사이의 많은 교차점을 분석하는 것뿐만 아니라, 한자와 한글(조선글) 간의 역사적 때때로는 상반되는 관계 및 이중성을 맥락화하는 것이다. 해방 후 수십 년 동안 남북한의 한자에 대한 입장과 정책은 다양하게 변화해 왔고, 그것은 한자폐지 혹은 한글(조선글)전용의 강제로 시작하여 한자교육의 재건이나 강화 등으로 나타났다. 한 세기 이상에 걸쳐 한국(조선)인들은 “문자의 문제”에 대해 사회적으로 이루어진 내러티브에 입각하여 반응했다. 이 현상은 구성주의 패러다임을 통해 볼 수 있으며, 또는 도구적 민족주의를 증명하는 실용 정책의 구현이라 해석될 수도 있다. 본 논문은 한국(조선) 민족주의의 이중(二重)문자 갈등에 관한 변동적 반응이 한국(조선)의 민족주의 즉, 한국(조선)의 정체성을 형성해 가는 복잡한 합류점임을 밝힌다.Niniejszy artykuł stanowi wieloaspektowy przegląd „punktów stycznych” między koreańskim nacjonalizmem w obu Koreach a chińskimi znakami (Hanja). W tym aspekcie ukazuje również kontekstualizację historyczną, występujący niekiedy przeciwstawny związek czy istniejącą „podwójność”, która składa się z Hanja i Han’gŭl (Chosŏn’gŭl). W powstałych po wyzwoleniu dwóch państwach koreańskich w ciągu kolejnych kilku dekad znaki chińskie były nadal stosowane różnorodnie w różnym czasie. Zastanawiano się nad zniesieniem (likwidacją) Hanja i wprowadzeniem wyłącznie pisma koreańskiego, jak i nad przywróceniem i umocnieniem edukacji Hanja. Koreańczycy od ponad wieku odnoszą się do „kwestii pisma” w oparciu o społecznie tworzone narracje. Zjawisko to może być rozważane (analizowane) przez paradygmaty konstruktywistyczne lub może być postrzegane (tłumaczone) jako wprowadzenie pragmatycznych zasad ukazujących instrumentalny nacjonalizm. W kontekście koreańskiego nacjonalizmu pokazano konflikt dotyczący stosowania w Koreach dwuznaku (podwójności pisma: Hanja i Han’gŭl (Chosŏn’gŭl), co powiązane jest z kształtowaniem się koreańskiego nacjonalizmu etnicznego, a zatem i koreańskiej tożsamości narodowej

Tax Depreciation and Risk

The theoretically ideal tax depreciation rule under an accretion tax is economic depreciation, a stream of deductions that replicates the decline in value of an asset over time. When the future value path of an asset is known in advance, the tax depreciation schedule should be based on the age-price profile for surviving assets. When the future value path of an asset is uncertain, this approach fails. A taxpayer can accelerate the statutory schedule by "strategic loss-taking." A series of special disposition rules (where each rule is combined with an adjustment in the ex ante depreciation schedule) address this problem, but each such rule has particular disadvantages. Finally, strategic loss-taking and rules designed to address it are particularly important in formulating a policy toward group accounting methods of depreciation

The Bankruptcy of Conventional Tax Timing Wisdom is Deeper than Semantics: A Rejoinder to Professors Kaplan and Warren

The Haig-Simons ideal is an important normative concept. But using it requires that one specify a method of measuring the value of changes in wealth. I use market value and present value, the concepts of value employed in modern finance theory. Professors Kaplow and Warren disagree with a result that I show follows from those concepts of value: That the CFIT implements the Haig-Simons ideal in a non-general-equilibrium setting. But their critique is ineffective because they do not present an alternative concept of value and give reasons for using it in the definition of the Haig-Simons ideal instead of market value or present value. It is questionable whether such an alternative concept can be constructed that is also consistent with the idea of value contained in modern finance theory. Professors Kaplow and Warren generally agree with my position that it is important to take general equilibrium effects into account in assessing alternative tax policies. But their attempt to make a general equilibrium argument for the equivalence of the CFIT and yield exemption fails. In fact, using their approach reinforces the conclusion in my original article that the equivalence holds in a non-general-equilibrium setting only for breakeven transactions
