    Ph.D.We investigate the DK conjecture on derived categories of coherent sheaves stated by Bondal-Orlov and Kawamata: there should be a derived embedding for any flip and in particular a derived equivalence for any flop. Unlike the situations for flops, there are few examples of flips proven to satisfy the DK conjecture except for some toroidal flips.We construct new examples of flips from Grassmannians, called Grassmannian flips, that satisfy the DK conjecture.我們對由彭督-奧爾洛夫(Bondal-Orlov)和川又(Kawamata)提出關於凝聚層的導出範疇相關的DK猜測進行探討:即對於任何翻轉(flip),都應該有導出(範疇的)嵌入,尤其是對於任何平轉 (flop),都應該有導出(範疇的)等價。與平轉(flop)的情況不同,除了一些環形翻轉(toroidal flips) 之外,鮮有反轉的例子證明能夠被證明滿足DK猜想。我們從格拉斯曼簇出發構造了滿足DK猜想的新例子,稱為格拉斯曼翻轉(Grassmannian flips)。Xie, Ying.Thesis Ph.D. Chinese University of Hong Kong 2020.Includes bibliographical references (leaves 84-88).Abstracts also in Chinese.Title from PDF title page (viewed on February 7, 2022)

    This study takes its problem based starting point in the stagnant growth and decreased competitiveness in the Danish economy. We have used statistics from the Global Competitiveness Report and the final report from the Productivity commission to show, that the Danish economy is doing worse than the economy in countries which vi normally compare ourselves too. In light of the condition of the economy which is described above, the Danish government (at that time; S, R, SF), along with Venstre, De Konservative and Liberal Alliance has implemented a plan called Vækstplan DK to secure growth and employment in the private sector and improve the competitiveness in an international perspective. This report will include a document analysis of the first two reform tracks from Vækstplan DK as they have the assignment of improving the aforementioned conditions. The structure of the report is hypothetical-deductive, as we will use Michael E. Porter and John M. Keynes as an operational theoretical apparatus to answer our problem formulation. Based on our results from the analysis we conclude that Vækstplan DK has several initiatives to improve conditions in the Danish economy. It includes that there are initiatives to boost the Danish economy through public investment. The theory of Keynes is used to prove how these public investments will result in a multiplier and thus create effective demand, increase production and provide growth. The plan also includes initiatives which will improve the framework conditions for Danish companies through long-term structural and institutional reforms. The theory of Porter emphasizes how lowering of taxes will increase competition in the domestic market, which will improve the state’s competitiveness in a number of areas. Furthermore, better and more effective training of the labor force contributes to productivity and innovation in enterprises, which will improve the long-term competitiveness. However, our analysis also shows that Vækstplan DK could have been more ambitious. This refers not to the proportions of the initiatives that are part of the plan, but that the competitiveness could have been further improved trough modifying the structure of income tax, which would result in greater incentive for both work and education. This report therefore fulfills its purpose; as our hypothetical-deductive approach ensures validity to the results from our analysis thus answer our problem formulation.This study takes its problem based starting point in the stagnant growth and decreased competitiveness in the Danish economy.

    Arva Novella Ghoibunka, 49124468.N, Unloading Cargo Handling Coal Has Been Burned in MV. DK 01 Supervisor : (1) Dr. Capt. Tri Cahyadi,M.H,M.Mar (2) Drs.Marmin,MM Implementation of the unloading of coal that has been burning required good handling and correct . Fire load should be prevented by handling cargo for on the boat, but the fires often occur during the process of demolition . On that basis the authors formulate the problem of how the process of loading the coal has been burned in the MV. DK 01 and what are the actions to be taken by the ship crew to prevent coal cargo fires . In writing this essay , the author describes the theory of handling unload coal has been burned are used in the manufacture of the research report and as a basis for solving the existing problems in the research process . Based on the results of research by the author during practice sailing on the MV. DK 01 regarding the handling of cargo unloading coal has been burned discovered the existence of problems in the implementation of the burning unloading cargo cover over the cargo handling is not exactly on board , the lack of coordination between the crew aboard the shipper regarding the nature of the charge , the charge is too old to be in hatch , less precise fire fighting coal in the hold and the less skilled crane operator . Due to the above problems during the process of unloading the coal cargo has been delayed . From the above analysis it can be concluded that the implementation of the process of loading and unloading on the ship MV. DK 01 is still often experience problems, especially during the demolition process, which is due to the lack of regular monitoring of the state of charge of coal for sailing boats and actions taken by the boat crew to avoid the charge of coal fires are still not in accordance with the provisions contained in the MSDS ship namely by using foam, carbon dioxide, dry chemical and water fog. The author's suggestion is better handling of cargo fires during the process of demolition remain guided by or in accordance with the demolition of the existing procedures on board and international rules as listed in the IMSBC, Better when it will carry out the process of loading the first implementation of a briefing or safety meeting the ship with the foreman to exchange information on measures to be taken to prevent the occurrence of fire load, so if there is a fire load, fire can be extinguished quickly and precisely.

    Evaluation of the FWF Doctoral Programme (DK Programme)

    No full text
    In the winter term 2013 a total of 27,634 doctoral students were enrolled at Austrian universities and a total of 2,165 students obtained a doctoral degree; thereof 204 (9.4%) students graduated in a PhD Programme. In total 7,158 doctoral students were employed at Austrian universities in 2012. These numbers include those doctoral students with temporary positions who were funded by competitive means, as provided by the funding programmes of the FWF. In total the FWF as the most important funding agency for basic research in Austria funded 1,967 doctoral candidates in 2013. In the period from 2004 to 2013 the FWF Doctoral Programme funded 1,121 doctoral candidates. From these 302 (27%) have already successfully completed their doctoral degree, while 756 doctoral candidates had the status of an ‘on-going’ student at the time of data collection. In this period the FWF received about 135 DK proposals, from these 42 were selected for funding in an international peer review. The budget for these 42 Doktoratskollegs (DK) amounts to 130.6 million Euros. In the recent years the number of first proposals for the DK Programme has been increasing. This is also due to a change in the governmental steering of higher education: Different incentives to increase the acquisition of competitive means have been implemented. However, as the FWF has to face serious budget constraints the approval rate of new proposals has been strongly decreasing in the recent years. In 2013 the approval rate of proposals for the first funding period was at 31% related to the number of proposals that have been handed in. Looking at the budget that has been applied for about 24% have been funded in 2013. A special characteristic of the FWF DK programme (compared to other FWF funding schemes) is that it is the only programme that funds excellent research as well as the training of young researchers. The funding of the training of young researchers aims in particular at establishing a well-functioning and excellent training environment for the most talented young researchers. The significance of the FWF DK Programme The vision to create and support an excellent environment for doctoral training that should serve as a role model across disciplines has proven to be very appropriate. So far, the idea to change the cultures of doctoral training also in the Social Sciences and Humanities fundamentally has not been realized to its fullest extent. Different reasons account for this: on the one hand the DK implemented in these disciplines are still quite young. On the other hand it has to be considered for these disciplines that the master-apprentice model is deeply ingrained in their doctoral training cultures. When looking at the overall performance of the DK programme, its impact on doctoral training at Austrian universities, and the incentives that the programme provided for the reform of doctoral training it can be stated that the DK Programme has achieved these goals to a very high extent. With the DK Programme new forms of doctoral training, in particular structural doctoral training based on excellent research, have been implemented as role models at Austrian universities. The DK Programme appeals high-level researchers and is rated as an excellence programme by institutions inside and outside academia. In this respect stakeholders emphasise the importance of the quality assurance mechanisms that have been established by the FWF; in particular the international peer review is seen as a major factor for these achievements. How does the DK Programme perform? The FWF DK Programme performs very well, in particular in the Life Sciences where almost half of the DK that have been funded DK since 2004 have been established. As main success factors the interdisciplinary approach, IHS – CHEPS – AIT – Evaluation of the FWF Doctoral Programme (DK Programme) - 11 the team building among students and faculty, the building of a critical mass in specific research fields and the promotion of visibility can be mentioned. The possibility to include associated doctoral candidates is very much welcomed as it further contributes to the visibility of a DK. Also, DK gain more visibility the longer they are established. The long funding of up to 12 years at maximum builds an important incentive for Priniciple Investigators to apply for a DK; also the possibility to promote and train bright, talented early stage researchers is an asset to apply for a DK. A further asset of the programme is its bottom-up principle. Here researchers are allowed to choose their research topics freely, i.e. they are not bound to any thematical limitation of the funding scheme. Most of the DK are established in research fields where universities have already built up competences and allocate ressources. Here in particular the Special Research Centers (SFB) of the FWF and the Christian Doppler Labatories play an important role as they provide additional resources for the DK. The strength of collaboration is determined by the discipline. In the Social Sciences and Humanities the DK often collaborate with stand-alone research projects. All in all, the majority of Principal Investigators stated that the DK Programme is the only funding programme (besides the Special Research Programs) that supports the establishment of sustainable research capabilities at Austrian universities. Internationalisation In the DK internationalisation is mainly facilitated by (1) the recruitment of international doctoral candidates and (2) the optional fourth year of funding for those internal doctoral candidates that have been spending three months abroad within the first three years of funding. The recruitment of international doctoral candidates has been realized to a large extent in the DK (on average 57% of the doctoral candidates per DK come from abroad); this strongly contributes to the visibility of the DK. International visibility and the recruitment of the most talented doctoral candidates also depends on the reputation of the host institution. There are some risks associated with the international recruitment, as stakeholders reported that they are not always able to select the best students. Nonetheless, the international recruitment is very much appreciated by the majority of the respondents and regarded as an added value for the DK as well as the host universities. As regards the rule to award a fourth year of funding in case the doctoral candidate has been abroad for about three months within the first three years of funding the majority of the Principal Investigators and the representative of doktorat.at were critical as this would couple funding too strongly to internationalisation activities. These advocates would prefer that research stays abroad should mainly serve the actual research project and the training of the individual students as some research projects would require only short stays abroad while for others longer research stays would be adequate. In this respect the respondents indicated that a more flexible regulation would be very much appreciated. All in all, it has to be stated that the opportunities to internationalize in the DK Programme, i.e. to engage in international cooperation and networks is very much recognized as an important added value by the doctoral candidates as well as the faculty of the DK. Funding of internal doctoral candidates In general, internal doctoral candidates are funded for a three-year period by the DK Programme. The funding period can be extended by an additional fourth year in case the doctoral student spends a continuous research stay of three months abroad. The length of this continuous research stay is considered as too long by a number of the Principal Investigators of the DK. Also, in practice the majority of the internal doctoral candidates do not use this opportunity to prolong their funding. This requires them to either complete their doctoral studies within the time frame of three years or to raise additional funds to extend their time of doctoral studies. Here in most interviews it was reported that only a limited number of doctoral candidates has completed their doctoral study within the three year funding period. Unfortunately, due to missing data we are not able to make reliable conlusions on the success of doctoral candidates and their time-to-degree in the DK. Because of confidentiality reasons not all data on this issue were accessible for the evaluation team. Nonetheless, different studies show that the time to degree differs by discipline (Enders and Kottmann, 2009; Bornmann and Enders, 2002). For the future we recommend to change the regulations as regards the funding periods of doctoral students. For the funding of young research talent the FWF should consider that conducting excellent and high quality research needs an adequate amount of time. Thus, the needs of the planned research should become a major factor in the determination of the funding period. Therefore it should already be stated in the project proposals whether three or four yours will be needed to complete the planned research. Employment and gender equality In general all internal doctoral candidates are employed in the framework of the collective agreement for an amount of 75% of full-time employment at their host institutions; that are about 30 hours per week. The possibility to employ doctoral candidates is valued as a major asset of the DK Programme by the representatives of the doctoral candidates as well as by the majority of the Principal Investigators. At some institutions, in particular at technical universities the employment is amended to a full-time position by additional funds from other project fundings etc. Only very few Principal Investigators stated that they would prefer to provide the funding by fellowships rather than by employment. This would definitely not be in line with the European Charter for Researchers and the Code of Conduct for the Recruitment of Researchers that aims at realising good working conditions for early stage researchers. The DK Programme actively supports female talent in science, this is done by a 30% quota for females among faculty. From the data it became clear that among doctoral students nearly a balance in the participation of females and males has been achieved: on average about 46% of the students in the DK were females. At the faculty level there was a growing awareness about the goal to increase the percentage of females among the faculty members. Unfortunately the goal has not been realized yet. Depending on the discipline it is hard to realize the integration of a sufficient number of females: in some disciplines there are only a few female professors, also a lack of excellent research among female faculty was mentioned here. Most of the speakers of DK tried to compensate the lack of female faculty by increasing the number of female doctoral students. This practice confronts the speakers of DK with new challenges: practices in achieving a more family friendly work environment are discussed, additionally it was mentioned that more family friendly regulations need to be developed. Universities’ views on the DK Programme In the view of the university managements the FWF Doctoral Programme is an excellence scheme, the DK are internally brand marked as excellent. This view is strongly supported by the quality assurance implemented by the FWF. Because of this excellence confirmed by the FWF allows researchers to request commitment by the university management in terms of additional funds and resources. In this respect the DK are sometimes evaluated as expensive. The kind and amount of support provided for the DK strongly depends on the university’s budget and the actors involved. While representatives of the university management strongly welcome the establishment of a DK as a means to strengthen the profile of their institution. The performance agreements between the universities and the federal government also explicitly consider the establishment of new and the continuation of existent DK. Impact of DK on doctoral training The visibility and the impact of a DK at universities depend to a large extent on the time it has been existing at its host institution. Generally, the majority of (guest) lectures and some other training events are open to all doctoral students at the host institution. Only a number of trainings that have in particular been designed for the DK (like hands on training in laboratories) are limited to the doctoral students of the DK. To what extent the doctoral training in the DK is different from doctoral training outside a DK is mainly dependent on the discipline and also the host institution. At some departments there is actually no difference between the both forms of training, here the DK mainly provide add-ons to doctoral training like the funding of a coordinator, international recruitment, travel costs, research stays abroad, the chance to invite international guest researchers or the funding of summer schools. There are also differences in the way doctoral training inside and outside the DK is organized. In particular in the Life Sciences structural forms of doctoral training are already common. Also in the Natural and Technical Sciences structural forms of doctoral training became more widespread (also depending on the faculty). In the Social Sciences and Humanities structural doctoral training only plays a minor role. In this disciplines the DK only function as a leverage to a very limited extent. This is also due to the fact that there are only a few DK established in these disciplines and that most of these are still young. Thus, doctoral training outside the DK is very different from training inside the DK for these disciplines, and the traditional master-apprenticeship is still prevalent here. In line with this the DK are regarded as highly specialised training centres that in particular prepare for an academic career in the Social Sciences and Humanities. The complementary role of the DK Programme In the recent years Austrian universities started own initiatives in structural doctoral training. These were mostly related to the developments on the European level, in particular the Bologna process. Also the implementation of the DK Programme has contributed to this development as it funds the implementation of structural elements in doctoral training. Besides this, there is a multitude of different initiatives to reform doctoral training in Austria. At the University of Vienna for example the so-called Initiativkollegs have been implemented. These are currently replaced by the Vienna Doctoral Academies and the funding of individual doctorates (uni:docs). At the University of Graz and Technical University of Graz Doctoral Schools have been implemented. Also at Medical Universities PhD programmes became more widespread as these institutions had to change their curricula in line with the Bologna reforms. Some Medical Universities also established doctoral schools, e.g. the Medical University of Graz. Here the guidelines of the FWF DK Programme served as a role model; also the quality assurance of the doctoral schools is organized by the FWF. Summarizing these developments there are a number of initiatives and reforms implemented at universities that build on the experiences that were made within the framework of the FWF DK Programme. For the funding of doctoral candidates a number of different models have been implemented: Some universities (University of Vienna, University of Salzburg, Veterinary University) fund positions for doctoral candidates, also as part-time employment. Other universities do not fund positions for doctoral candidates in the framework of their doctoral schools (e.g. University of Klagenfurt). Some universities also provide additional positions for doctoral candidates in the FWF DK (e.g. Medical University of Vienna), other prolong the funding of doctoral candidates for a limited period in case the funding for the FWF DK stops (e.g. University of Economics Vienna). In total all of these initiatives and activities have a common goal: they motivate to further proceed with the implementation of structural doctoral training and to increase the quality of doctoral studies in Austria. The increase in the quality of doctoral study should include a more sensitive usage of resources and synergies and the strategic linkage of those initiatives to the profile building of the universities. Also, a more tactical approach in the regulation of the so far open access to doctoral studies in Austria should be considered. Nonetheless, when considering further changes it should be clear that the resources of universities are limited, they cannot provide as many ressources as the FWF DK Programme and might in their initiatives not achieve a similar effect. In this respect it has to be stated that the FWF DK has a very important complementary role to the initiatives and activities implemented by universities. The university’s commitment Facing the increasing numbers of applications for the FWF DK Programme and the current budget constraints of the FWF it has to be investigated to what extent the universities will be able to increase their commitment towards the DK. In particular the question to what extent the universities can realistically contribute to the costs of a DK in order to decrease the funding provided by the FWF. Therefore in the evaluation different scenarios on the future funding of the DK have been discussed with the Principal Investigators of the DK and the managing board of universities (Rectors and Vice-Rectors). These discussions revealed that currently the universities will not be able to further contribute to the costs of the DK (besides their actual commitments). Also the fact that the FWF currently does not contribute to the overhead costs of large-scale research projects (and thus also not for the DK) needs to be considered here. Those scenarios that described a situation where the FWF would only provide initial funding or where universities would have to cover an increasing amount of the costs of the DK were rated as inpracticable or even as an illusion given the current tight budget of Austrian universities. Only very few Principal Investigators could image that the funding of the FWF would gradually decline. Summing up the statements of the representatives of universities it can be concluded that most universities already participate to the funding of DK to a large extent (provision of additional funds, additional positions for doctoral students, provision of research infrastructure, reduction of the teaching load for Principal Investigators). In the current situation an additional contribution to the DK was seen as a too big burden for the university’s budget. Conclusion The evaluation of the FWF DK Programme revealed that it is functioning very well. Researchers as well as the university management evaluate the programme as an excellence scheme. The programme achieved most of its goals (good performance in research, implementation of structural elements in doctoral training, internationalisation etc.). The programme also functions as a stimulus for the further reform and improvement of doctoral training in Austria. Here the programme serves as a role model and plays via funding an important complementary role. Nonetheless, experiences from other European countries point to an on-going further reform of doctoral training in the recent years. In particular in the Nordic countries (Denmark, Norway and Finland) the training component of doctoral training has become central. Also an increase in the number of doctoral graduates should be achieved in these countries. In line with these targets ministries have been changing the funding mechanism related to doctoral training, also universities have been assigned more responsibility in providing a high quality in (structural) doctoral training. In these countries doctoral training is to a large extent funded by the institutions, mostly by earmarked funds. These changes also led to change in the work of the research councils that had to reorient their funding schemes for doctoral candidates/young researchers. So far Austria has been using two different but complementary approaches in doctoral training: on the one hand doctoral training is funded by the global budget of the universities, on the other hand additional means (as the FWF DK Programme) are allocated by competitive means. Both funding mechanism have to be regarded as indispensable and contribute to maintain doctoral training in Austria. For the future the implementation of a unit cost funding model has been included in the intergovernmental agreement. This potential development might also affect the FWF DK Programme, therefore a need to reorient the programme might be considered. Until then the FWF DK Programme should be continued under the premise to fund excellent research and the most talented doctoral students

    Contextualising the issue: Leadership in corrections

    No full text
    Modern correctional leaders are challenged by immediate country and system-specific dynamics and demands. Illustrated by Cavadino and Dignan (2006), for example, the political economy of countries, broadly categorised as neo-liberal, conservative corporatist, social democratic or oriental corporatist, is strongly related to the punitiveness of the penal culture and rates of imprisonment in each country. Also, few countries can ignore the evolving international norms that shape international, national, and system based regulatory and auditing practices within their bailiwicks. Recent international developments referred to by correctional leaders in this volume include the Nelson Mandela Rules (United Nations General Assembly Resolution 70/175 of 2015) a set of human rights guidelines for correctional administrators formerly known as the United Nations Standard Minimum Rules for the Treatment of Prisoners. Noted as a rapidly-developing pressure, too, is the cooperation between national and international assessors created in those countries where UN member states have ratified the Optional Protocol to the Convention Against Torture along with the monitoring of prisoner rights by the Human Rights Committee overseeing the UN’s International Covenant on Civil and Political Rights. These norms and processes are not dissimilar to the move to design and regulate official visitor regimes within regional human rights and political frameworks such as those of the European Union

    Nu-DESC DK: the Danish version of the nursing delirium screening scale (nu-DESC)

    No full text
    Abstract Background Delirium is one of the most common complications among elderly hospitalized patients, postoperative patients and patients on intensive care units with a prevalence between 11 and 80%. Delirium is associated with higher morbidity and mortality. Reliable instruments are required to detect delirium at an early time point. The Nursing-Delirium Screening Scale (Nu-DESC) is a screening tool with high sensitivity and good specificity. However, there is currently no official translation after ISPOR guidelines of any Danish delirium assessment tools available. Thereby hampering the implementation of 2017 ESA-Guidelines on postoperative Delirium in the clinical routine. The aim of this study is to provide an official translation and evaluation of the Nu-DESC into Danish following the ISPOR process. Methods The Nu-DESC was translated after International Society for Pharmacoecomonics and Outcome Research (ISPOR) guidelines to Danish after permission of the original author, and is evaluated by medical staff and finally approved by the original author. Results All steps of the ISPOR guideline were consecutively followed, without any major problems. The evaluation of the Nu-DESC DK regarding its intelligibility and feasibility showed no statistically significant differences between nurses and medical doctors ratings. The translation was authorized and approved by the original author. Conclusion This study provides the Nu-DESC DK, an official Danish delirium screening instrument, which can detect all psychomotor types of delirium

    Relativistic segmented contraction basis sets with core-valence correlation effects for atoms 57La through 71Lu : Sapporo-DK-nZP sets (n = D, T, Q)

    No full text
    For the 15 lanthanide atoms 57La through 71Lu, we report Sapporo-DK-nZP sets (n = D, T, Q), which are natural extensions of the Sapporo-(DK)-nZP sets for lighter atoms and efficiently incorporate the correlation among electrons in the N through P shells as well as the relativistic effect. The present sets well describe the correlation among the 4s and 4p electrons, which are important in the excitation of 4f electrons. Atomic test calculations of 57La, 58Ce, 59Pr, and 60Nd at configuration interaction with the Davidson correction level of theory confirm high performance of the present basis sets. Molecular test calculations are carried out for 57LaF and 70YbF diatomics at the coupled cluster level of theory. The calculated spectroscopic constants approach smoothly to the experimental values as the quality of the basis set increases

    The Gender Gap in Political Knowledge: Is It All About Guessing? An Experimental Approach

    No full text
    This article analyzes the extent to which the format and the “Do not know” (DK) protocol of political knowledge questions influence the size of the gender gap. By using a set of experiments that manipulated the DK protocol and the format (open vs. closed ended) of political knowledge questions in a face-to-face representative survey of the Spanish population, we show that the format of the questions (open vs. closed ended) is not relevant in explaining the gender gap. DK protocols, however, influence outspoken levels of political knowledge differently for men and women. DK-discouraging protocols tend to encourage the emergence of hidden knowledge among women, whereas they mostly boost guessing among men. This finding suggests that the meaning and the use of the DK option appear to be gender biased
