Automatic coding of short text responses via clustering in educational assessment

Automatic coding of short text responses opens new doors in assessment. We implemented and integrated baseline methods of natural language processing and statistical modelling by means of software components that are available under open licenses. The accuracy of automatic text coding is demonstrated by using data collected in the Programme for International Student Assessment (PISA) 2012 in Germany. Free text responses of 10 items with Formula responses in total were analyzed. We further examined the effect of different methods, parameter values, and sample sizes on performance of the implemented system. The system reached fair to good up to excellent agreement with human codings Formula Especially items that are solved by naming specific semantic concepts appeared properly coded. The system performed equally well with Formula and somewhat poorer but still acceptable down to Formula Based on our findings, we discuss potential innovations for assessment that are enabled by automatic coding of short text responses.

A system for monitoring NO2 emissions from biomass burning by using GOME and ATSR-2 data

In this paper, we propose a system for monitoring abnormal NO2 emissions in troposphere by using remote-sensing sensors. In particular, the system aims at estimating the amount of NO2 resulting from biomass burning by exploiting the synergies between the GOME and the ATSR-2 sensors mounted on board of the ERS-2 satellite. Two different approaches to the estimation of NO2 are proposed: the former, which is the simplest one, assumes a linear relationship between the GOME and ATSR-2 measurements and the NO2 concentration. The latter exploits a nonlinear and nonparametric method based on a radial basis function (RBF) neural network. The architecture of such a network is defined in order to retrieve the values of NO2 concentration on the basis of the GOME and ATSR-2 measurements, as well as of other ancillary input parameters. Experimental results, obtained on a real data set, confirm the effectiveness of the proposed system, which represents a promising tool for operational applications

Intellectual Property Challenges in Replicating an American Graduate Program in Poland Experiences, Perspectives, and Lessons Learned

The article delineates some of the challenges in implementing of one of the global trends among universities - increased cooperation and collaboration to create and transfer intellectual property. Universities all over the world are increasing cooperation and collaboration in different fields. In addition to the traditional student and faculty exchanges, more and more universities are exploring deeper collaborations ranging from replication of degree programs to creation of dual degree programs. The article presents a case study of an extended collaboration to replicate a program founded by the University of Texas at Austin at the University of Lodz in Lodz, Poland. The transferred program is the year long executive MS in Science and Technology Commercialization (MSSTC) Program which focuses on wealth creation associated with intellectual property by transforming ideas based on science and technology into new products, new services, and new ventures to create jobs. The MSSTC program was transferred successfully from the University of Texas at Austin to the University of Lodz in Poland. However, one of the most significant challenges associated with the program replication across countries and cultures is how to best address a program’s intellectual property issues. This paper examines some of the intellectual property issues involved in transferring the MSSTC program like from a US to a Polish university. Some of the lessons learned re: intellectual property are delineated, examined, explored, and recommendations offered.Globalne trendy i międzynarodowy charakter komercjalizacji technologii sprawia, że pojawiły się globalne trendy do zacieśnienia współpracy pomiędzy uczelniami. Uniwersytety Trzeciego wieku oprócz misji edukacyjnej i naukowej włączają się w nurt przedsiębiorczości nazwanej akademickiej, współpracy z przemysłem i instytucjami rządowymi. Artykuł zwraca uwagę na istotną rolę transferu własności intelektualnej zawartej w programach edukacyjnych, szkoleniowych wymiany kadry i studentów. Współpraca rodzi wartość dodaną jako uzyskują uczelnie w postaci wspólnych programów lub transferu wiedzy z jednej uczelni do drugiej. Prezentowany artykuł zawiera również studium przypadku oparte na współpracy dwóch uczelni amerykańskiej i polskiej oraz transferze programu magisterskiego Komercjalizacji Nauki i Technologii z Austin do Łodzi. Udostępnienie wiedzy i najlepszych praktyk Instytutu IC2 w Austin obejmowało wyzwania związane z prawidłowym transferem własności intelektualnej wielu podmiotów jak wykładowców, uczelni, instytutu, doradców oraz innych osób pracujących przez wiele lat przy tworzeniu najlepszego w USA programu magisterskiego do zarządzania technologią.

Mutually Assured Survival: A Constructivist Analysis of Transnational Cultural Interactions and Their Influence on Nuclear Disarmament Initiatives

Nuclear arms have revolutionized the ways by which human beings are able to harm one another. Omnipresent in the status quo is a nuclear tension, and whether subtly or more overtly, this tension underlies a great many international relationships. While Westphalian paranoia and neorealist power perceptions encourage populations to continue placing their faith in nuclear umbrellas and deterrence strategies, scholars and activists increasingly claim that without the realization of universal disarmament, humanity concedes to the inevitability of future nuclear detonation. New disarmament initiatives concentrate heavily on the implications of nuclear weaponry in a sense that supersedes the security of only particular sovereign populations. Rooted in constructivist theory that stresses the importance of processes and relationships to the international system, these new initiatives seem to be gaining momentum. As the world continues to globalize, transnational cultural interactions may be stimulating the development of increasingly worldly identities more prone to support disarmament campaigns. Not only are we witnessing a pivot toward a more holistic devotion to the global good and global identities, but we are also seeing increasingly frequent normative attacks on nuclear legitimacy and a transition toward international collective security architecture, both of which seem to manifest as a result of the identity shifts themselves. The following research utilizes a qualitative, interview-based model and will discuss the future feasibility of disarmament initiatives with a particular concentration on constructivist perceptions of the international system

miR-9 Acts as an OncomiR in Prostate Cancer through Multiple Pathways That Drive Tumour Progression and Metastasis

Identification of dysregulated microRNAs (miRNAs) in prostate cancer is critical not only for diagnosis, but also differentiation between the aggressive and indolent forms of the disease. miR-9 was identified as an oncomiR through both miRNA panel RT-qPCR as well as high-throughput sequencing analysis of the human P69 prostate cell line as compared to its highly tumorigenic and metastatic subline M12, and found to be consistently upregulated in other prostate cell lines including DU-145 and PC3. While miR-9 has been characterized as dysregulated either as an oncomiR or tumour suppressor in a variety of other cancers including breast, ovarian, and nasopharyngeal carcinomas, it has not been previously evaluated and proven as an oncomiR in prostate cancer. miR-9 was confirmed an oncomiR when found to be overexpressed in tumour tissue as compared to adjacent benign glandular epithelium through laser-capture microdissection of radical prostatectomy biopsies. Inhibition of miR-9 resulted in reduced migratory and invasive potential of the M12 cell line, and reduced tumour growth and metastases in male athymic nude mice. Analysis showed that miR-9 targets e-cadherin and suppressor of cytokine signalling 5 (SOCS5), but not NF-ĸB mRNA. Expression of these proteins was shown to be affected by modulation in expression of miR-9
