The application of a technique for enhancing recall to improve learning in the science classroom

Parsons, Darryl C January 2007 (has links)
There has existed for many years a memory enhancement technique ("memory pegs") that although having dramatic demonstrable success in some individual cases has not been generally applied in education. The emergence of constructivist epistemology has emphasised the notion that learning occurs as a result of connecting new material with previously learnt concepts. There is, therefore, the implication that effective learning requires some previous knowledge upon which to attach new concepts - and thus realisation of the importance of learning with respect to acquiring factual information as a prerequisite to learning new processes and/or skills. This issue has focussed my attention on the need to ensure that the more physiological skills of accessing 'memory', both for learning and recall, are optimised for maximum learning. Further, there are some indications that the physiological skills of memory access (storage and retrieval) may respond favourably to training and 'exercise'. This study was designed to find out whether or not a repeated 'exercise' using a simple memory enhancement technique would lead to a determinable and statistically significant increase in overall performance in a range of cognitive skills (as indicated by science and mathematics examination results), whether learning such a technique would affect a student's attitudes towards science, whether there was a relationship between the amount of time spent practicing the technique and the degree of effect, and whether the memory technique did actually improve the ability to recall lists of objects.

Learning Mathematics through Scientific Contents and Methods

Beckmann, Astrid 12 April 2012 (has links) (PDF)
The basic idea of this paper is to outline a cross-curricular approach between mathematics and science. The aim is to close the often perceived gap between formal maths and authentic experience and to increase the students’ versatility in the use of mathematical terms. Students are to experience maths as logical, interesting and relevant through extra-mathematical references. Concrete physical or biological correlations may initiate mathematical activities, and mathematical terms are to be understood in logical contexts. Examples: physical experiments can lead to a comprehensive understanding of the concept of functions and of the intersection of medians in triangles. Biological topics can lead to the concepts of similarity and proportion as well as to the construction of pie charts. In the European ScienceMath Project a variety of teaching modules was developed and tested in secondary schools.

A contra-reforma do Estado e o financiamento da seguridade social: 1995 a 2002

Sader, Débora 30 October 2006 (has links)
Made available in DSpace on 2016-12-23T14:36:44Z (GMT). No. of bitstreams: 1 A contra-reforma do Estado e o financiamento da Seguridade Social - 1995 a 2002.pdf: 1001008 bytes, checksum: 93aaac1432b6d1aede0c3c946600717f (MD5) Previous issue date: 2006-10-30 / Trata do financiamento da Seguridade Social no Brasil no contexto da contra-reforma do Estado na década de 1990 e início dos anos 2000, focando o período do governo Fernando Henrique Cardoso (1995 2002). A Seguridade é uma das formas da intervenção pública do governo, com o objetivo de promover sua legitimação. A partir de uma problematização teórico-histórica sobre a teoria do Estado, base para os estudos, é discutida a construção do conceito de Seguridade no país e a regulamentação das políticas que a compõem Previdência, Assistência e Saúde , além da contra-reforma do Estado no Brasil e seus efeitos sobre essa política. Apresenta considerações sobre as alterações nas políticas componentes da Seguridade, discorrendo sobre a contra-reforma da Previdência Social com a incorporação da lógica atuarial à concessão dos benefícios; sobre a assistencialização das políticas sociais e o aumento dos gastos com a Assistência Social, ainda que em nível insuficiente para lidar com as mazelas sociais do país; e sobre o processo de implantação do Sistema Único de Saúde, que trouxe uma valorização da atenção básica à saúde e dos mecanismos de descentralização dos recursos, ficando os municípios responsáveis por boa parte da operacionalização e financiamento da política. A partir da discussão sobre o financiamento público, é ressaltada a predominância da valorização financeira do capital com a destinação de parcela crescente dos recursos arrecadados pelo governo para garantir a acumulação. Os principais mecanismos nesse sentido são os instrumentos de desvinculação das receitas, agora comprometidas com o pagamento dos juros da dívida, e as metas de resultado primário positivo. A intervenção pública dos anos 90 pautou-se pela busca da estabilização da economia, sobre-valorizando a importância de uma política econômica de cunho contracionista e conduzindo a cortes nos gastos públicos para a área social com a finalidade de pagar parte dos juros da dívida pública, ou seja, remunerar o capital especulativo e manter calmos, ou melhor, satisfeitos, os ditos mercados . Na medida em que avançou a penetração da ideologia neoliberal na sociedade e a utilização dos recursos arrecadados em nome da Seguridade para os gastos específicos foi reduzida, as possibilidades para a efetivação dessa política enquanto intervenção pública consolidada pioraram, dependendo cada vez mais de uma mobilização social nesse sentido.

Modeling The Temperature of a Calorimeter at Clab : Considering a Thermodynamic Model of The Temperature Evolution of The Calorimeter System 251

Ekman, Johannes January 2021 (has links)
It is important to know the heat generated due to nuclear decay in the final repository for spent nuclear fuel. In Sweden, the heating powers generated in spent nuclear fuels are currently measured in the calorimeter System 251 at the Clab facility, Oskarshamn. In order to better measure, and increase understanding, of the temperature measurements in the calorimeter, a simple thermodynamic model of its temperature evolution was developed. The model was described as a system of ordinary differential equations, which were solved, and the solution was applied to calibration measurements of the calorimeter. How precise the model is, how its parameters affect the model, et cetera, are addressed. How the temperature evolution of the system changes as the values of parameters in the model are changed is addressed. The mass correction of the calorimeter could be estimated from this model, which validated the established mass correction of the calorimeter. How the measurement results from the calorimeter would be affected if the volume of the calorimeter was changed was also considered. Additionally, gamma radiation escape from the calorimeter without being detected as heat in the calorimeter. The gamma escape energy fraction was estimated by SERPENT simulations of the calorimeter, as a function of the initial photon energy. The gamma escape was also estimated for different values of the radius of System 251.

A 64-channel back-gate adapted ultra-low-voltage spike-aware neural recording front-end with on-chip lossless/near-lossless compression engine and 3.3V stimulator in 22nm FDSOI

Schüffny, Franz Marcus, Zeinolabedin, Seyed Mohammad Ali, George, Richard, Guo, Liyuan, Weiße, Annika, Uhlig, Johannes, Meyer, Julian, Dixius, Andreas, Hänzsche, Stefan, Berthel, Marc, Scholze, Stefan, Höppner, Sebastian, Mayr, Christian 21 February 2024 (has links)
In neural implants and biohybrid research systems, the integration of electrode recording and stimulation front-ends with pre-processing circuitry promises a drastic increase in real-time capabilities [1,6]. In our proposed neural recording system, constant sampling with a bandwidth of 9.8kHz yields 6.73μV input-referred noise (IRN) at a power-per-channel of 0.34μW for the time-continuous ΔΣ−modulator, and 0.52μW for the digital filters and spike detectors. We introduce dynamic current/bandwidth selection at the ΔΣ and digital filter to reduce recording bandwidth at the absence of spikes (i.e. local field potentials). This is controlled by a two-level spike detection and adjusted by adaptive threshold estimation (ATE). Dynamic bandwidth selection reduces power by 53.7%, increasing the available channel count at a low heat dissipation. Adaptive back-gate voltage tuning (ABGVT) compensates for PVT variation in subthreshold circuits. This allows 1.8V input/output (IO) devices to operate at 0.4V supply voltage robustly. The proposed 64-channel neural recording system moreover includes a 16-channel adaptive compression engine (ACE) and an 8-channel on-chip current stimulator at 3.3V. The stimulator supports field-shaping approaches, promising increased selectivity in future research.

特約條款之檢討與重構 / The examination and reconstruction of express warranties of insurance law in Taiwan

陳豐年, Chen, Lawrence Unknown Date (has links)
由於過度粗糙立法、缺乏相關深入研究暨流於形式之契約解釋取向,臺灣保險契約法第二章第三節特約條款制度實沈苛已深而積重難返,亟待立法者、司法者及主管機關進行大幅度改造。本文研究聚焦於探討該制度-相當於英美保險契約法之明示擔保條款-起源、本質暨新近發展,並研擬相關修法提案俾供後續立法者與研究者參酌。基此,本文擬採用法律經濟分析、實證分析與比較法等研究方式加以進行。從英美法系各國之立法潮流可發現,契約基礎條款因違反合理期待原則而遭多數國家揚棄。此從英格蘭暨蘇格蘭法律委員會目前保險契約法修法暫時提案,以及澳洲1984年保險契約法第24條規定即可窺見一斑。再者,鑑於肯定擔保條款當初建制基礎已消失殆盡,包含英國、澳洲及紐西蘭皆採取以不實陳述制度取代肯定擔保條款之立法,俾以達成較為公平之規範結果。至於允諾擔保條款部分,增加損失與違反行為間因果關係要件實已蔚為潮流,包含英國、美國數州、澳洲及紐西蘭相關立法皆為適例。此外,相較於無效、得撤銷抑或自動向後免責,賦予保險人契約終止權誠屬較佳之法律效果,已獲各國之共識。職是之故,本文主張應修改特約條款有關肯定特約部分相關文字,使同法第64條據實說明制度可取代之,俾產生較有效率之核保資訊提供制度。另一方面,允諾擔保條款內容應限縮於與危險有關之重要性事項。此外,應考慮增加損失與違反行為間因果關係要件,並使保險人於無因果關係之情形得以主張就系爭損失免責。鑑於解除權易使法律關係趨於複雜,本文建議應以契約終止權取代現行契約解除權較佳。又在前述修法前,法院得透過契約解釋方式緩和現行法弊端,而行政院金融監督管理委員會亦得透過保險商品審查機制過濾不妥之約款加以因應。 / Express warranties of insurance law in Taiwan provoke a great number of dilemmas in both theory and practice due to oversimplified legislation, a paucity of related studies and formalism of contract construction. This study aims not only at exploring the origin, nature and development of the institution for the purpose of elucidating pros and cons of express warranties, but also at providing an amendment to express warranties of insurance law in Taiwan. The dissertation achieves the dual goals by way of comparative study and economic analysis of law. Obviously, abolition of “basis of the contract clause”-an obsolete and bitterly-criticized contract term- has been an uncontroversial trend around the world on the grounds of reasonable expectations. English and Scottish Law Commissions’ tentative proposals, as well as Section 24 of Australian Insurance Contracts Act 1984, sets an excellent example. Also, with an eye to the collapse of affirmative warranties’ keystones, several countries, including the U.K., Australia, and New Zealand, substitute misrepresentation for affirmative warranties for the purpose of leveling the playing field. As for promissory warranties, requirement of causal link between losses and breach of promissory warranties has gained a dominant position in the U.K., the U.S., Australia, and New Zealand on the grounds that considerable unfairness to policyholders would arise in the absence of it. In addition, the insurers’ right to terminate contracts has been generally regarded as a more superior legal effect than III rendering contracts void or avoid, even the insurer automatically discharged from liability. Based upon these foreign legislation and other considerations, the dissertation proposes the third section “express warranties” of insurance law in Taiwan should be amended thoroughly. Affirmative warranties in the section should be substantially supersede by misrepresentation set forth in article 64, since the latter is capable of inducing the insured to provide necessary information for the insurer in a more efficient way than is the former. On the other hand, promissory warranties of insurance law in Taiwan should be reconstructed by adding the requirement of causal connection to the insurer’s right not liable for specific losses. Furthermore, this dissertation also advocates that legislators replace the insurer’s right to avoid with the right to terminate on the basis of evading complicated legal relationship. Besides, in advance of amending aforementioned articles, the dissertation suggests that courts in Taiwan mitigate harsh effects via contract construction, and regulators should filter inappropriate or nominal warranties from insurance policies by means of administrative screening mechanism.

Tredjemanskontroll - Säker rätt är säkert rättssäker : En studie med utgångspunkt i betänkandet Förbudet mot dubbla förfaranden och andra rättssäkerhetsfrågor i skatteförfarandet (SOU 2013:62) / Third party control : A study based on a public inquiry concerning Rule of Law in tax procedures (SOU 2013:62)

Fjällman, Emelie January 2014 (has links)
SKV and Tullverket have several important tools and methods available in each activity to ensure that taxes and fees are paid and charged rightfully. Among other things they use tax or customs surcharges, targeted and general third party injunctions or targeted and general third party audits. The targeted controls, ergo targeted injunctions and audits, are targeted towards specific persons or documents while during the general controls these are not specified. The methods have repeatedly been the subject of discussions and attempts to simplify the tax procedure and increase the Rule of Law for the individual. The government appointed a commission on March 8 of the year 2012 with the assignment to prepare proposals to increase the Rule of Law in the tax procedure. The assignment was therefore to analyze the areas of tax and customs injunctions, reimbursement because of expenses and agents and also third party controls. This study was delimited, partly due to space considerations, to examine the commission's proposals to increase the Rule of Law regarding third party controls as well as to SKV as the investigating authority. Consideration will therefore not be given to Tullverket as the investigating authority. The system concerning third party controls has repeatedly over the years been the subject of criticism and debate. Not least because of that the general third party controls are indistinct due to the fact that the person who is the subject of the control is not aware of the control and that the procedure is considered to contravene the protection of privacy in the RF and the right to private and family life of the ECHR. It has hence been considered that there is a need for change. The commission would thus investigate and make proposals to increase the Rule of Law but given the precondition that third party control, including general controls, would still remain as control methods. Therefore the commission had to consider a proportionality assessment between the protection of individual privacy and SKV:s control effectiveness. In this study focus was on SOU 2013:62 and the consultation bodies’ responses received on account of the proposals. The commission proposed that the decision making on general third party controls will stay with SKV as the decision making authority and that it should be clarified in the legislative text that SKV has to relate to the principle of proportionality when deciding on general third party controls. The commission also proposed that it should be clarified in the legislative text that SKV only may search for documents and information covered by the decision but that surplus information that was discovered spontaneously also may be used. The commission held that there is no need for clarification of the legislative texts regarding that SKV shall take into account the proportionality principle in the choice of method and choice of control object. The commission also held that there is no need to legislate any imposes for SKV towards the subject of control to inform about the control if the information gathered nevertheless is intended to be the basis for decisions on taxation. Furthermore it was proposed an imposition of legislative texts regarding that the controlled, in connection with the information about the control, should be given the opportunity to request documents and information excluded from the basis for decisions on taxation. That is, after the control is carried out and provided that the information will be added basis for decisions on taxation. The majority of the consultation bodies felt that the commission was inadequate, that the proposals did not add anything new on the merits and that a new commission should be appointed with the mission to increase the Rule of Law in the tax procedure. The studies’ concluding parts contain a pro et contra analysis of the proposals on the basis of the consultation bodies’ responses, my own conclusions and general concluding comments. In these parts my own proposals are submitted for improvement to further enhance the Rule of Law in tax procedures. My own proposals are due to that the commission in my opinion may be deemed deficient in several aspects. / SKV och Tullverket har flera viktiga metoder att tillgå i respektive verksamhet för att säkerställa att skatter och avgifter lämnas och tas ut rätteligen. Bland annat så kan kontrollmyndigheterna använda skatte- eller tulltillägg, riktade och generella tredjemansförelägganden eller riktade och generella tredjemansrevisioner. Vid riktade kontroller, ergo riktade förelägganden och riktade revisioner, är kontrollerna riktade mot specificerade personer eller handlingar och vid generella kontroller är dessa inte specificerade. Metoderna har upprepade gånger varit föremål för diskussioner och försök att förenkla skatteförfarandet och öka rättssäkerheten för den enskilde. Regeringen tillsatte den 8 mars år 2012 en utredning med uppgiften att framställa förslag för en ökad rättssäkerhet i skatteförfarandet. Uppdraget var att undersöka områdena skatte- och tulltillägg, ersättning för kostnader och ombud samt tredjemanskontroller. Denna studie har bland annat på grund av utrymmesskäl avgränsats till att undersöka utredningens förslag som avser ökad rättssäkerhet vid tredjemanskontroller samt till SKV som kontrollerande myndighet. Hänsyn kommer således inte tas till Tullverket som kontrollerande myndighet. Tredjemanskontrollförfarandet har upprepade gånger genom åren varit föremål för kritik och diskussioner. Inte minst för att generella tredjemanskontroller ansetts olämpliga på grund av att den kontrollerade inte har vetskap om att denna är eller har varit föremål för kontroll samt att förfarandet ansetts strida mot integritetsskyddet i RF och rätten till privat- och familjeliv i EKMR. Det har därav ansetts att behov av förändring föreligger. Utredningen skulle således undersöka och lämna förslag för att öka rättssäkerheten för den enskilde men med hänsyn till att tredjemanskontroller, i dessa inbegripet generella tredjemanskontroller, alltjämt skulle kvarstå som metod i SKV:s kontrollverksamhet. Det fordrades följaktligen av utredningen att genomföra en proportionalitetsavvägning mellan skyddet för den enskildes integritet och SKV:s kontrolleffektivitet. I denna studie har fokus lagts på SOU 2013:62 och de remissyttranden som inkommit med anledning av förslagen. Utredningen föreslog att beslutsordningen vid generella tredjemanskontroller ska stå oförändrad med SKV som beslutsfattande instans och att det ska förtydligas i lagtext att SKV ska förhålla sig till proportionalitetsprincipen vid beslut om generella tredjemanskontroller. Utredningen föreslog även att det ska förtydligas i lagtext att SKV endast får eftersöka handlingar och uppgifter som omfattas av beslutet men att överskottsinformation som anträffats spontant får användas. Vidare angav utredningen att det inte behövs något förtydligande i lagtext avseende att SKV ska beakta proportionalitetsprincipen vid val av metod och val av kontrollobjekt. Utredningen angav även att det inte behöver införas någon underrättelseskyldighet för SKV gentemot den kontrollerade om informationen som inhämtats ändå inte är avsedd att läggas till grund för beslut om beskattning. Vidare föreslogs ett införande i lagtext avseende att den kontrollerade ska ges möjlighet att begära handlingar och uppgifter undantagna från att läggas till grund för beslut om beskattning i samband med en underrättelse, det vill säga efter att kontrollen ägt rum och under förutsättning att informationen kommer läggas till grund för beslut om beskattning. Flertalet remissinstanser ansåg att utredningen var bristfällig, att förslagen inte innebar någonting nytt i sak samt att en ny utredning bör tillsättas med uppdrag att öka rättssäkerheten i skatteförfarandet. I studiens avslutande delar redovisas en pro et contra-analys av förslagen med utgångspunkt i remissyttrandena, egna slutsatser avseende förslagen samt allmänna avslutande kommentarer. I dessa delar lämnas egna förbättringsförslag för att ytterligare öka rättssäkerheten, eftersom utredningen enligt min mening får anses bristfällig i flera avseenden.

Les moyens de défense contre les OPA hostiles / Antitakeover defenses

Maouche, Samia 27 November 2017 (has links)
Opérations particulièrement complexes, les offres publiques d'acquisition ne cessent de faire parler d'elles, plus particulièrement lorsqu'elles présentent un caractère hostile pour la société visée. De nombreux efforts législatifs ont été mis en œuvre en vue d'encadrer les OPA et de lutter contre les prises de contrôle rampantes. L'analyse du droit positif permet de mettre en lumière ces différents efforts ainsi que leur mise en œuvre à travers diverses techniques par les sociétés visées. Ces dernières ont par ailleurs développé un certain nombre de mécanismes de défense anti-OPA particulièrement efficaces, mais se révélant le plus souvent insuffisants face à l'ingéniosité dont peut faire preuve l'initiateur. Le droit positif montre ainsi ses limites face à des pratiques qui ne cessent d'évoluer. L'analyse prospective du droit anti-OPA permet d'observer les nouvelles mutations que subit le droit positif au regard des nouveaux enjeux économiques. Elle permet également d'envisager de nouveaux modes d'appréhension des OPA hostiles. Il est ainsi possible d'observer que le gouvernement d'entreprise prend une place considérable dans la vie des sociétés cotées. De même, la montée en puissance de la régulation et l'interventionnisme de l’État sont de plus en plus marqués ; et les salariés s'impliquent de plus en plus dans la gestion de l'entreprise. L'ensemble de ces paramètres marquent un glissement progressif vers une réorganisation du mode de fonctionnement des sociétés, ce qui a amené au développement du soft law, un droit à la frontière du droit positif et des pratiques des sociétés. Le soft law constitue à ce titre une approche inédite des OPA hostiles, dont l'analyse permet de cerner les apports liés à la mutation du droit positif et d'envisager l'émergence de nouveaux moyens de défense. Celui-ci doit toutefois demeurer complémentaire au cadre législatif et réglementaire existant. / No abstract
