Aktiiviseen kansalaisuuteen kasvattaminen yläkoulun maantieteen opetuksessa

Tutkielmassa tarkasteltiin aktiivista kansalaisuutta perusopetuksen yläkoulun (luokat 7–9) maantieteen opetuksessa. Tutkielman taustana olivat aktiiviseen kansalaisuuteen liittyvät viralliset ja epäviralliset diskurssit: opetussuunnitelman perusteiden aihekokonaisuudet, kouluun kohdistuvat kansalaiskasvatushankkeet sekä nuoriin, kansalaisuuteen ja kansalaisyhteiskuntaan liittyvät keskustelut. Maantieteen opetuksen osalta taustana olivat opetussuunnitelman velvoitteet huomioida aktiivinen kansalaisuus yläkoulun maantieteen opetuksessa sekä (pääasiassa brittiläinen) kirjallisuus, jossa maantieteen ja kansalaiskasvatuksen/aktiivisen kansalaisuuden välillä nähdään yhtäläisyyksiä. Tutkielmassa pyrittiin selvittämään, mitä aktiivinen kansalaisuus on yläkoulun maantieteen opetuksessa ja miten maantieteen opettajat suhtautuvat tehtäviinsä nuorten kansalaisten kasvattajina ja yhteiskunnallisina vaikuttajina. Tutkielmaa varten kerättiin teemahaastatteluaineisto kuudelta yläkoulun maantieteen opettajalta. Haastatteluihin pyrittiin löytämään mahdollisimman aktiivisia maantieteen opettajia. Haastatteluaineiston analyysissa käytettiin sisällönanalyysia, ja aineiston avulla pyrittiin kuvaamaan ilmiötä. Haastateltujen opettajien mukaan yläkoulun maantieteen opetuksessa luonnonmaantieteelliset sisällöt painottuvat enemmän kuin kulttuurimaantieteelliset. Aktiivisen kansalaisuuden kannalta keskeisiä sisältöjä, kuten vaikutusmahdollisuuksia oman ympäristön suunnitteluun ja kehittymiseen sekä kotikunnan ja lähiympäristön tutkimista käsitellään opetuksessa vain vähän, jos ollenkaan. Aktiivinen kansalaisuus on yläkoulun maantieteen opetuksessa eniten tiedon jakamista, ajattelun taitojen ja mielipiteen muodostamisen harjoittelua sekä ympäristövastuullisuuteen kansalaisuuteen kasvattamista. Opetuksessa käytetään myös aktiivisen kansalaisuuden kannalta keskeisiä työtapoja, mutta työtapojen käyttö vaihtelee. Haastatellut opettajat eivät koe opetussuunnitelman aihekokonaisuuksia juurikaan omakseen. Opettajat eivät myöskään määrittele kansalaisvaikuttamiseen kasvattamista koulun tärkeimpien tehtävien joukkoon. Osa opettajista kokee kuitenkin olevansa yhteiskunnallinen vaikuttaja opettajana. Opettajien puheessa koulun kansalaiskasvatuksen tavoite, kunnon kansalainen, ei määrity kovin aktiivisena tai poliittisena. Opettajien puhe sisältää kuitenkin monenlaisia näkemyksiä suhteessa nuoriin kansalaisina ja aktiivisuuteen: toisaalta nuoret eivät ole kiinnostuneita yhteiskunnallisista asioista eikä heiltä vaaditakaan sitä, toisaalta maaperä nuorten kasvattamiseen aktiivisiksi kansalaisiksi on hyvä ja aktiivisuus on pieniä asioita lähiympäristössä sekä yhdessä tekemiseen uskomista. Haastattelujen pohjalta todettiin, että lukuun ottamatta joidenkin opettajien ympäristökasvatuksellista otetta, aktiivinen kansalaisuus ei ole täysin tiedostettu tavoite yläkoulun maantieteen opetuksessa.

An Analysis of the Concept of Citizenship: Legal, Political and Social Dimensions

The thesis aims at analyzing concept of citizenship in political philosophy. The concept of citizenship is a complex one: it does not have a definitive explication, but it nevertheless is a very important category in contemporary world. Citizenship is a powerful ideal, and often the way a person is treated depends on whether he or she has the status of a citizen. Citizenship includes protection of a person’s rights both at home and abroad. It entails legal, political and social dimension: the legal status as a full member of society, the recognition of that status by fellow citizens and acting as a member of society. The thesis discusses these three dimensions. Its objective is to show how all of them, despite being insufficient in some aspects, reach something important about the concept. The main sources of the thesis are Civic Republicanism by Iseult Honohan (Routledge 2002), Republicanism by Philip Pettit (Clarendon Press 1997), and Taking Rights Seriously by Ronald Dworkin (1997). In addition, the historical part of the thesis relies mainly on the works of Aristotle, Immanuel Kant, Adam Smith, Quentin Skinner, James Pocock and James Tully. The writings of Will Kymlicka, John Rawls, Chantal Mouffe, and Shane Phelan are referred to in the presentation and critique of the liberal tradition of thought. Hannah Arendt and Seyla Benhabib’s analysis of Arendt’s philosophy both address the problematic relations between human rights and nation-states as the main guarantors of rights. The chapter on group rights relies on Peter Jones’ account of corporate and collective rights, after which I continue to Seumas Miller’s essay on the (liberal) account of group rights and their relation to the concept of citizenship. Republicanism and Political Theory (2002) edited by Cécile Laborde and John Maynor is also references. David Miller and Maurizio Viroli represent the more “rooted” version of republicanism. The thesis argues that the full concept of citizenship should be seen as containing legal, political and social dimensions. The concept can be viewed from all of these three angles. The first means that citizenship is connected with certain rights, like the right to vote or stand for election, the right to property and so on. In most societies, the law guarantees these rights to every citizen. Then there is also the social dimension, which can be said to be as important as the legal one: the recognition of equality and identities of others. Finally, there is the political dimension, meaning the importance of citizens’ participation in the society, which is discussed in connection with the contemporary account of republicanism. All these issues are discussed from the point of view of groups demanding for group-specific rights and equal recognition. The challenge with these three aspects of citizenship is, however, that they are difficult to discuss under one heading. Different theories or discourses of citizenship each approach the subject from different starting points, which make reconciling them sometimes hard. The fundamental questions theories try to answer may differ radically depending on the theory. Nevertheless, in order to get the whole image of what the citizenship discourses are about all the aspects deserve to be taken into account.

Sosiaaliturvan ulkopuolella - kokemuksia kansalaisuuden reunalta

Muuttaessaan maasta toiseen ihminen kohtaa useita rajoja. Ylittäessään kohdemaan valtion rajan hän kulkee läpi ensimmäisestä maahanmuuton portista. Toinen raja erottaa tilapäiset asukkaat pysyvistä: tämän maahanmuuton toisen portin läpikulkemisen myötä yksilö pääsee osalliseksi sosiaalisista oikeuksista. Maahanmuuton viimeisestä portista kuljettuaan yksilö saavuttaa kyseisen valtion kansalaisuuden. (Hammar 1990, 21.) Tässä pro gradu -tutkielmassa tarkastelen toisen maahanmuuton portin aukeamista ja sosiaaliturvan piiriin pääsyä odottavien maahan-muuttajien kokemuksia. Käytän tarkastelussa sosiaalisen kansalaisuuden ja marginaalisuuden käsitteitä. Tutkielmassa selvitän, miten sosiaali- ja terveyspalveluiden sekä toimeentuloturvan ulkopuolelle jääminen vaikuttaa maahanmuuttajien arkeen ja miten he kokevat osallisuutensa ja jäsenyytensä yhteiskunnassa. Tutkimus on lähtökohdiltaan fenomenologis-hermeneuttinen ja sovellan lähestymistapana ko-kemuksiin keskittyvän narratiivista tutkimusta. Tutkimusaineisto on koottu kevään 2011 aikana ja se koostuu 10 teemahaastattelusta. Haastateltavien maahanmuuton keinot ja syyt vaihtelivat: he olivat saapuneet Suomeen perhesyistä, työn vuoksi tai hakeakseen turvaa. Haastateltavat tavoitettiin Helsingin Diakoniaopiston, Pro-tukipisteen, Kansainvälisen seurakunnan ja tuttava-verkostojen kautta. Aineiston analyysi toteutettiin sisällönanalyysillä Atlas-ohjelman avulla syksyn 2011 aikana. Toisen maahanmuuton portin aukeamisen odottaminen oli raskaaksi: tuota aikaa leimasi epä-varmuus, tyhjyys ja yksinäisyys. Sosiaaliturvan ulkopuolella jääminen aiheutti osalle haastatel-tavista taloudellisia vaikeuksia sekä ongelmia terveydenhuollon palveluiden piiriin pääsemisessä. Toisaalta apua hakeneet haastateltavat olivat sitä lopulta saaneet. Auttamistyön ammattilaiset ja maistraatti saivat haastateltavien kertomuksissa portinvartijan aseman. Kaikille sosiaaliturvan ulkopuolelle jääminen ei ollut ongelma vaan he kokivat sosiaaliturvan puutetta suuremmaksi ongelmaksi työnteko-oikeuden puuttumisen. Kuulumisen ja ulkopuolisuuden kokemus voivat olla läsnä samanaikaisesti, ja kuulumisesta neuvotellaan jatkuvasti esimerkiksi sosiaalisessa kanssakäymisessä tai palveluita hakiessa. Insti-tutionaaliset käytännöt ja poiskäännyttämisen kokemukset tuottavat marginaalisia identiteettejä. Tasavertainen oikeus sosiaaliturvaan vahvistaa kokemusta kuulumisesta ja kodista. Sosiaaliturva ei kuitenkaan yksin määritä kuulumisen ja kodin kokemusta vaan siihen vaikuttavat myös muut tekijät. Näistä tärkeimmät ovat kehon fyysinen sijoittuminen Suomeen, perhe- ja ystä-vyyssuhteet, työ, asunto ja rasismin kokemukset.

The Reception of the Maccabean Martyrs : Their Historiographical and Paradigmatic Functions in Antique and Late-antique Jewish and Christian Sources

The study attempts a reception-historical analysis of the Maccabean martyrs. The concept of reception has fundamentally to do with the re-use and interpretation of a text within new texts. In a religious tradition, certain elements become re-circulated and thus their reception may reflect the development of that particular tradition. The Maccabean martyrs first appear in 2 Maccabees. In my study, it is the Maccabean martyr figures who count as the received text; the focus is shifted from the interrelations between texts onto how the figures have been exploited in early Christian and Rabbinic sources. I have divided my sources into two categories and my analysis is in two parts. First, I analyze the reception of the Maccabean martyrs within Jewish and Christian historiographical sources, focusing on the role given to them in the depictions of the Maccabean Revolt (Chapter 3). I conclude that, within Jewish historiography, the martyrs are given roles, which vary between ultimate efficacy and marginal position with regard to making a historical difference. In Christian historiographical sources, the martyrs role grows in importance by time: however, it is not before a Christian cult of the Maccabean martyrs has been established, that the Christian historiographies consider them historically effective. After the first part, I move on to analyze the reception in sources, which make use of the Maccabean martyrs as paradigmatic figures (Chapter 4). I have suggested that the martyrs are paradigmatic in the context of martyrdom, persecution and destruction, on one hand, and in a homiletic context, inspiring religious celebration, on the other. I conclude that, as the figures are considered pre-Christian and biblical martyrs, they function well in terms of Christian martyrdom and have contributed to the development of its ideals. Furthermore, the presentation of the martyr figures in Rabbinic sources demonstrates how the notion of Jewish martyrdom arises from experiences of destruction and despair, not so much from heroic confession of faith in the face of persecution. Before the emergence of a Christian cult of the Maccabean martyrs, their identity is derived namely from their biblical position. Later on, in the homiletic context, their Jewish identity is debated and sometimes reconstructed as fundamentally Christian , despite of their Jewish origins. Similar debate about their identity is not found in the Rabbinic versions of their martyrdom and nothing there indicates a mutual debate between early Christians and Jews. A thematic comparison shows that the Rabbinic and Christian cases of reception are non-reliant on each other but also that they link to one another. Especially the scriptural connections, often made to the Maccabean mother, reveal the similarities. The results of the analyses confirm that the early history of Christianity and Rabbinic Judaism share, at least partly, the same religious environment and intertwining traditions, not only during the first century or two but until Late Antiquity and beyond. More likely, the reception of the Maccabean martyrs demonstrates that these religious traditions never ceased to influence one another.

Charge Density Analysis of Heterohalogen (Cl center dot center dot center dot F) and Homohalogen (F center dot center dot center dot F) Intermolecular Interactions

Experimental charge density distribution in 2-chloro-4-fluorobenzoic acid and 4-fluorobenzamide has been carried out using high resolution X-ray diffraction data collected at 100 K using Hansen-Coppens multipolar formalism of electron density. These compounds display short Cl center dot center dot center dot F and F center dot center dot center dot F interactions, respectively. The experimental results are compared with the theoretical charge densities using theoretical structure factors obtained from periodic quantum calculation at the B3LYP/6-31G** level. The topological features were derived from Bader's ``atoms in molecules'' (AIM) approach. Intermolecular Cl center dot center dot center dot F interaction in 2-chloro-4-fluorobenzoic acid is attractive in nature (type II interaction) while the nature of F center dot center dot center dot F interactions in 4-fluorobenzamide shows indication of a minor decrease in repulsion (type I interaction), though the extent of polarization on the fluorine atom is arguably small.

Electron diffraction structure analysis: structural research with low-quality diffraction data

Electron Diffraction Structure Analysis (EDSA) with data from standard selected-area electron diffraction (SAED) is still the method of choice for structure determination of nano-sized single crystals. The recently determined heavy atom structure α-Ti2Se (Albe & Weirich, 2003) is used as an example to illustrate the developed procedure for structure determination from two-dimensionally SAED data via direct methods and kinematical least-squares refinement. Despite the investigated crystallite had a relatively large effective thickness of about 230 Å as determined from dynamical calculations, the obtained structural model from SAED data was found in good agreement with the result from an earlier single crystal X-ray study (Weirich, Pöttgen & Simon, 1996). Arguments, which support the validity of the used quasi-kinematical approach, are given in the text. The influences of dynamical and secondary scattering on the quality of the data and the structure solution are discussed. Moreover, the usefulness of first-principles calculations for verifying the results from EDSA is demonstrated by two examples, whereas one of the structures was unattainable by conventional X-ray diffraction.

Charge Density Analysis of a Pentaborate Ion in an Ammonium Borate: Toward the Understanding of Topological Features in Borate Minerals

Structural and charge density distribution studies have been carried out on a single crystal data of an ammonium borate, [C(10)H(26)N(4)][B(5)O(6)(OH)(4)](2), synthesized by solvothermal method. Further, the experimentally observed geometry is used for the theoretical charge density calculations using the B3LYP/6-31G** level of theory, and the results are compared with the experimental values. Topological analysis of charge density based on the Atoms in Molecules approach for B-O bonds exhibit mixed covalent/ionic character. Detailed analysis of the hydrogen bonds in the crystal structure in the ammonium borate provides insights into the understanding of the reaction pathways that net atomic charges and electrostatic potential isosurfaces also give additional such systems. could result in the formation of borate minerals. The input to evaluate chemical and physical properties in such systems.

Performance analysis for geometrical attack on digital image watermarking

We present a technique for irreversible watermarking approach robust to affine transform attacks in camera, biomedical and satellite images stored in the form of monochrome bitmap images. The watermarking approach is based on image normalisation in which both watermark embedding and extraction are carried out with respect to an image normalised to meet a set of predefined moment criteria. The normalisation procedure is invariant to affine transform attacks. The result of watermarking scheme is suitable for public watermarking applications, where the original image is not available for watermark extraction. Here, direct-sequence code division multiple access approach is used to embed multibit text information in DCT and DWT transform domains. The proposed watermarking schemes are robust against various types of attacks such as Gaussian noise, shearing, scaling, rotation, flipping, affine transform, signal processing and JPEG compression. Performance analysis results are measured using image processing metrics.

Charge Density Analysis of Ferulic Acid: Robustness of a Trifurcated C-H center dot center dot center dot O Hydrogen Bond

The toplogical features of a sporadic trifurcated C-H center dot center dot center dot O interaction region, where an oxygen atom acts as an acceptor of three weak hydrogen bonds, has been investigated by experimental and theoretical charge density analysis of ferulic acid. The interaction energy of the asymmetric molecular dimer formed by the trifurcated C-H center dot center dot center dot O motif, based on the multipolar model, is shown to be greater than the corresponding asymmetric O-H center dot center dot center dot O dimer in this crystal structure. Further, the hydrogen bond energies associated with these interaction motifs have been estimated from the local kinetic and potential energy densities at the bond critical points. The trends suggest that the interaction energy of the trifurcated C-H center dot center dot center dot O region is comparable to that of a single O-H center dot center dot center dot O hydrogen bond.

MAST: multi-script annotation toolkit for scenic text

This paper describes a semi-automatic tool for annotation of multi-script text from natural scene images. To our knowledge, this is the maiden tool that deals with multi-script text or arbitrary orientation. The procedure involves manual seed selection followed by a region growing process to segment each word present in the image. The threshold for region growing can be varied by the user so as to ensure pixel-accurate character segmentation. The text present in the image is tagged word-by-word. A virtual keyboard interface has also been designed for entering the ground truth in ten Indic scripts, besides English. The keyboard interface can easily be generated for any script, thereby expanding the scope of the toolkit. Optionally, each segmented word can further be labeled into its constituent characters/symbols. Polygonal masks are used to split or merge the segmented words into valid characters/symbols. The ground truth is represented by a pixel-level segmented image and a '.txt' file that contains information about the number of words in the image, word bounding boxes, script and ground truth Unicode. The toolkit, developed using MATLAB, can be used to generate ground truth and annotation for any generic document image. Thus, it is useful for researchers in the document image processing community for evaluating the performance of document analysis and recognition techniques. The multi-script annotation toolokit (MAST) is available for free download.

MAPS: midline analysis and propagation of segmentation

Scenic word images undergo degradations due to motion blur, uneven illumination, shadows and defocussing, which lead to difficulty in segmentation. As a result, the recognition results reported on the scenic word image datasets of ICDAR have been low. We introduce a novel technique, where we choose the middle row of the image as a sub-image and segment it first. Then, the labels from this segmented sub-image are used to propagate labels to other pixels in the image. This approach, which is unique and distinct from the existing methods, results in improved segmentation. Bayesian classification and Max-flow methods have been independently used for label propagation. This midline based approach limits the impact of degradations that happens to the image. The segmented text image is recognized using the trial version of Omnipage OCR. We have tested our method on ICDAR 2003 and ICDAR 2011 datasets. Our word recognition results of 64.5% and 71.6% are better than those of methods in the literature and also methods that competed in the Robust reading competition. Our method makes an implicit assumption that degradation is not present in the middle row.

Genome-wide analysis correlates Ayurveda Prakriti

The practice of Ayurveda, the traditional medicine of India, is based on the concept of three major constitutional types (Vata, Pitta and Kapha) defined as ``Prakriti''. To the best of our knowledge, no study has convincingly correlated genomic variations with the classification of Prakriti. In the present study, we performed genome-wide SNP (single nucleotide polymorphism) analysis (Affymetrix, 6.0) of 262 well-classified male individuals (after screening 3416 subjects) belonging to three Prakritis. We found 52 SNPs (p <= 1 x 10(-5)) were significantly different between Prakritis, without any confounding effect of stratification, after 10(6) permutations. Principal component analysis (PCA) of these SNPs classified 262 individuals into their respective groups (Vata, Pitta and Kapha) irrespective of their ancestry, which represent its power in categorization. We further validated our finding with 297 Indian population samples with known ancestry. Subsequently, we found that PGM1 correlates with phenotype of Pitta as described in the ancient text of Caraka Samhita, suggesting that the phenotypic classification of India's traditional medicine has a genetic basis; and its Prakriti-based practice in vogue for many centuries resonates with personalized medicine.

A Perspective on Computer Assisted Assessment Techniques for Short Free-Text Answers

Computer Assisted Assessment (CAA) has been existing for several years now. While some forms of CAA do not require sophisticated text understanding (e.g., multiple choice questions), there are also student answers that consist of free text and require analysis of text in the answer. Research towards the latter till date has concentrated on two main sub-tasks: (i) grading of essays, which is done mainly by checking the style, correctness of grammar, and coherence of the essay and (ii) assessment of short free-text answers. In this paper, we present a structured view of relevant research in automated assessment techniques for short free-text answers. We review papers spanning the last 15 years of research with emphasis on recent papers. Our main objectives are two folds. First we present the survey in a structured way by segregating information on dataset, problem formulation, techniques, and evaluation measures. Second we present a discussion on some of the potential future directions in this domain which we hope would be helpful for researchers.

Disaggregation of LST over India: comparative analysis of different vegetation indices

The non-availability of high-spatial-resolution thermal data from satellites on a consistent basis led to the development of different models for sharpening coarse-spatial-resolution thermal data. Thermal sharpening models that are based on the relationship between land-surface temperature (LST) and a vegetation index (VI) such as the normalized difference vegetation index (NDVI) or fraction vegetation cover (FVC) have gained much attention due to their simplicity, physical basis, and operational capability. However, there are hardly any studies in the literature examining comprehensively various VIs apart from NDVI and FVC, which may be better suited for thermal sharpening over agricultural and natural landscapes. The aim of this study is to compare the relative performance of five different VIs, namely NDVI, FVC, the normalized difference water index (NDWI), soil adjusted vegetation index (SAVI), and modified soil adjusted vegetation index (MSAVI), for thermal sharpening using the DisTrad thermal sharpening model over agricultural and natural landscapes in India. Multi-temporal LST data from Landsat-7 Enhanced Thematic Mapper Plus (ETM+) and Moderate Resolution Imaging Spectroradiometer (MODIS) sensors obtained over two different agro-climatic grids in India were disaggregated from 960 m to 120 m spatial resolution. The sharpened LST was compared with the reference LST estimated from the Landsat data at 120 m spatial resolution. In addition to this, MODIS LST was disaggregated from 960 m to 480 m and compared with ground measurements at five sites in India. It was found that NDVI and FVC performed better only under wet conditions, whereas under drier conditions, the performance of NDWI was superior to other indices and produced accurate results. SAVI and MSAVI always produced poorer results compared with NDVI/FVC and NDWI for wet and dry cases, respectively.
