title: An Evaluation Of Trainee Teachers' Perceptions Of Mentoring
Creators: name: Burrill, Paul Geoffrey
Publisher: name: The Open University
Year: 2003

description: This thesis on trainee teachers' perceptions of mentoring is concerned with the I Year PGCE (secondary), programme at St. Martin's College, Lancaster, England. The study took place between 1999-2002.

 The use of the term mentoring and the set of processes it might involve have been integrated into Initial Teacher Training (ITT) courses in little over a decade. There is little published information about trainees' perceptions of mentoring, especially post DfEE 4/98.

 The focus for the study was sharpened by key questions that investigated trainees' perceptions of mentoring, mentoring strategies related to the planning, teaching and evaluation of lessons, reflective practice and professional development.

 Both quantitative and qualitative methodologies were used. Building on a pilot study (1999-2000) questionnaire, observational and interview data were collected from trainees in the main study (2000-2001). The entire cohorts of PGCE (sec) Science and Modem Foreign Languages trainees were used in the questionnaire surveys (N = 100) with smaller samples for the interview and observational studies. Data were also collected from school mentors and college tutors, which provided triangulation on perceptions of mentoring from different audiences. Additionally, via letter, 101 Course Leaders of secondary PGCE courses in other ITT institutions in England were contacted. Their responses helped to inform, update and relate this research to a wider field.

 The findings show that trainee teachers sometimes had different perceptions of mentoring to their mentors. Most trainees believed that mentoring should be a nurturing process and individual feedback time with mentors and teachers should continue throughout the course and be built into their timetable. Solo teaching was trainees' most valued teaching strategy but this often became a private, lonely and uncertain activity, again signalling the need for formal mentor support and feedback. The strategy of paired teaching practice placements in school departments conveyed advantages to most trainees as it allowed them to support each other both emotionally and with teaching materials. By the end of the course not only had trainees made cuts in lesson preparation time they had often reduced or stopped formalised reflection, such as keeping reflective diaries and writing lesson evaluations.

 The new information from this study is used to suggest improvements for PGCE (sec) courses at St. Martin's College. However, due to National similarities in PGCE course structure (DfEE 4/98, DEES 02/02) a number of the findings from this study may also have value, in similar courses, in other ITT institutions.

description: The event rate and the efficiency of mass estimation for free-floating planet (FFP) microlensing events were determined from the simulation of the simultaneous parallax observations by Euclid, WFIRST, and LSST. The stellar population from the Besançon Galactic model toward $(l, b)=(1^{\circ},-1.^{\circ}75)$ was applied to our 3D microlensing model, and 30,000 parallax observations were simulated for each following FFP lens masses: Jupiter-mass, Neptune-mass, and Earth-mass assuming the population of one FFP per star. The interstellar dust, unresolved stellar background, nearby star blending were modelled. A signal-to-noise limit considering a finite source effect determined the event detectability. The Euclid-WFIRST combination yielded 30.7 Jupiter-mass FFPs during two 30-day-periods per year in parallax observation. The parallax event rate decreases to 3.9 FFPs for Earth-mass planets. The mass estimation from the parallax light curve allowed recovery of FFP masses to within a factor of two for 20-26% of cases. The Euclid-LSST combination yielded 34.5 Jupiter-mass FFPs down to 0.5 Earth-mass FFPs for the same periods and the mass is recovered to within a factor of two in 20-40% of cases. The event rate will be normalised by the unknown FFP abundance to recover the number of expected detections.

description: We report a numerical study, covering a wide range of packing fraction $ϕ$ and temperature $T$, for a system of particles interacting via a square well potential supplemented by an additional constraint on the maximum number $n_{\rm max}$ of bonded interactions. We show that when $n_{\rm max}<6$, the liquid-gas coexistence region shrinks, giving access to regions of low $ϕ$ where dynamics can be followed down to low $T$ without an intervening phase separation. We characterize these arrested states at low densities (gel states) in terms of structure and dynamical slowing down, pointing out features which are very different from the standard glassy states observed at high $ϕ$ values.

description: The abundance stratification in the ejecta of the normal Type Ia supernova 2002bo is derived by fitting a series of spectra obtained at close time intervals. A Monte Carlo code, modified to include abundance stratification, is used to compute synthetic spectra at 13 epochs in the photospheric phase, starting 13d before B maximum. A description of the abundance distribution above 7600 km/s is thus obtained. Abundances in deeper layers, down to zero velocity, are derived from models of two nebular-phase spectra. Elements synthesized in different stages of burning are significantly, but not completely, mixed in the ejecta. A total 56Ni mass of 0.52M_sun is derived. Evidence for intermediate-mass elements at high velocities (> 18 000 km/s) is found, most clearly in Si II 6355A, in Ca II H&K, and in the Ca II infrared triplet. Carbon lines are not seen at any velocity, with possible implications for the progenitor/explosion scenario. A synthetic bolometric light curve computed using the inferred abundance distribution is in very good agreement with the observed one, providing an independent check. In particular, the fast rise of the light curve is reproduced very well. This is due to outward mixing of 56Ni, which is clearly well determined by the spectroscopic modelling.

description: We investigate land-use dynamics in Jambi, Sumatra, one of the hotspots of Indonesia’ recent oil palm boom. Data from a structured village survey are used to analyze the role of socioeconomic and policy factors. Oil palm is partly grown on large plantations, but smallholders are also involved significantly. We find that, in spite of significant oil palm expansion, rubber remains the dominant crop. Most of the oil palm growth takes place on previous fallow and rubber land. Oil palm has not been a major driver of deforestation. Much of the forest in Jambi was cleared more than 20 years ago, and rubber was an established cash crop long before the oil palm boom started. However, oil palm growth occurs in locations with ongoing logging activities, so indirect effects on deforestation are likely. The government’s transmigration program of the 1980s and 1990s was instrumental for the start and spread of oil palm in Jambi. Some autochthonous villages have adopted oil palm, but adoption started later compared to migrants from Java, and it happens at a slower pace. While the transmigration program benefited many of the participating families, it has contributed to the risk of unequal socioeconomic developments in Jambi.
title: Promoting equality in primary education : putting policy into practice in one local education authority
Creators: name: Dawson, Hilary Margaret
Publisher: name: The Open University
Year: 2004

description: This study considers, from the perspective of the Local Education Authority Officers working there, how one English Shire County, Trentshire', promotes equality in its primary education service. Set in the wake of the Macpherson Report, it investigates the pressures for local government of implementing a social justice agenda alongside other initiatives in an existing framework of neo-liberal legislation promoting effectiveness, `performativity' and school improvement. It is not concerned with pedagogic practice, but considers how LEA administrators promote equality and diversity while working in a context where LEAs have lost most of their former power but are still expected to take a leadership role, where relationships with school Heads and governors are frequently uneasy and where parents increasingly insist on their individual 'rights'. A Trentshire' LEA Officer myself, I argue that, although the power of LEAs in relation to schools has diminished, individual officers retain a key role in promoting equality. I research from the 'inside', and adopt a critical theory perspective shaped by my personal desire for a just society free from inequalities of race, gender or disability. Arguing that policy implementation is complex, messy and dynamic, involving social action by real people, I reject a positivist strategy based on quantitative outcomes analysis, claiming that insight into the views and behaviours of key players is a stronger basis for researching policy. My principal evidence comes from interviews with colleague LEA Officers whose day-to-day role brings them into contact with schools and parents, and I also use evidence from meeting notes to critically consider the actions taken by 'Trentshire' Officers in three separate scenarios. My findings reveal 'Trentshire' Officers' personal commitment and their pragmatic determination to solve dilemmas and make policies 'work' in spite of political and structural tensions inherent in their roles and the conceptual tensions within the equality and diversity agendas; they are required to uphold weak 'equal treatment' procedures grounded in neo-liberal legislation whilst increasingly delivering a social inclusion / diversity agenda based on postmodern conceptions of difference. They use their discretion to develop working definitions of equality and to adopt their own ad hoc 'first-order' strategies for change, and as the LEA's role extends into partnership with public sector and voluntary agencies, have a wider opportunity to contribute positively to the promotion of social justice. My study concludes with brief thoughts on building strategies to make equality a reality in 'Trentshire'.

description: We review the current state of experimental and theoretical investigations of heavy fermion superconductors. We discuss most of the Ce-based compounds like Ce122, Ce115, Ce218 and Ce131 classes and U-based superconductors like UBe_13 and UPd_2Al_3. In the former the emphasis is on the connection to quantum critical phenomena and non-Fermi liquid behaviour. Recent neutron scattering and hydrostatic pressure results on SDW/SC competition in the Ce122 system are included. For the U-compounds we discuss the significance of dual models with both localised and itinerant 5f electrons for mass enhancement and superconducting pair formation. Itinerant spin fluctuation theories for unconventional superconductivity are also reviewed.

The role of podocalyxin in adhesion and cell morphogenesis
Creators: name: Nielsen, Julie Susanne
Publisher: name: University of British Columbia
Year: 2010

description: Podocalyxin is a sialomucin expressed on kidney podocytes, vascular endothelia, and hematopoietic progenitors. Although podocalyxin and its close relative, CD34 have been studied for many years, their precise functions have remained elusive, and roles in blocking differentiation, preventing cell adhesion, and establishing cell polarity have all been proposed. Despite this ambiguity, the perinatal lethality of podocalyxin knockout mice (as a result of kidney defects) and podocalyxin’s close association with cancer progression highlight its biological importance. I therefore used several strategies to clarify podocalyxin’s functions and mechanisms of action. Podocalyxin was overexpressed in epithelial cells, and I observed a striking decrease in cell adhesion and an induction of microvillus formation. Microvillus formation was then used as the endpoint to assess the activity of podocalyxin mutants: the extracellular domain was essential while most of the cytoplasmic tail could be deleted without loss of this function. These in vitro studies also demonstrated that podocalyxin recruits the scaffolding protein, NHERF1, which may have important implications in the regulation of NHERF-related processes, such as interaction with ion transporters and signalling molecules. In order to study podocalyxin in vivo, generation of conditional podocalyxin overexpressing mice was attempted. The intention was to generate a single floxed podxl transgenic mouse line that could be crossed with numerous Cre mice in order to induce podocalyxin expression in selected tissues. For example, podocalyxin overexpression in mammary tissue was intended to facilitate evaluation of podocalyxin’s role in breast cancer progression. Similarly, these mice could be used to selectively rescue defects in podocalyxin-deficient mice. Unfortunately, chromosomal abnormalities in the parental embryonic stem cells temporarily prevented completion of this study. As an alternative strategy, we attempted to selectively rescue the kidney defects observed in podocalyxin-null mice by creation of mice with a kidney-specific podxl transgene. Surprisingly, although transgenic podocalyxin was appropriately expressed, and podocyte morphology appeared relatively normal in contrast to podocalyxin-null mice, transgenic mice still died perinatally. This suggests the presence of other serious, as yet undetermined, abnormalities in podocalyxin-deficient animals. Continued assessment of these defects and podocalyxin’s role in cancer progression is underway. In summary, this thesis reveals a new mechanistic role for podocalyxin in the process of cell morphogenesis and suggests that in addition to its vital role in kidney development, podocalyxin may play an essential role in other aspects of mammalian development.

description: With the Marchenko method it is possible to retrieve the wave field inside a medium from its reflection response at the surface. To date, this method has predominantly been applied to naturally occurring materials. In this paper we extend the Marchenko method for applications in metamaterials with, in the low-frequency limit, effective negative constitutive parameters. We illustrate the method with a numerical example, which shows that the method works well for vertically propagating plane waves and for dipping plane waves with small horizontal slownesses. The proposed method has potential applications for example in non-destructive testing of layered materials.

We present results for small baryon numbers, where the sign problem can be controlled, in particular by supplementing the mu=0 sampling with imaginary mu ensembles. We initiate the thermodynamic study of few-nucleon systems, starting with the measurement of the free energy of a few baryons in the confined and deconfined phase. We present a simple model for the phase transition, whose results are in good agreement with the literature, but extend to lower temperatures.

description: We study lattice QCD with a gauge action, which suppresses small plaquette values. Thus the MC history is confined to a single topological sector over a significant time, while other observables are decorrelated. This enables the cumulation of statistics with a specific topological charge, which is needed for simulations of QCD in the $ε$-regime. The same action may also be useful for simulations with dynamical quarks. The update is performed with a local HMC algorithm.

Creators: name: Bräutigam, Lisa
Year: 2023

description: Beim Übereinkommen über die Rechte von Menschen mit Behinderungen handelt es sich um eine verbindliche Rechtsquelle, die 2008 in Österreich in Kraft getreten ist. Dennoch bestehen auch heute noch Barrieren, die Menschen behindern. Eine Beschäftigung mit den Wurzeln von Abwertung und Repression, mit der systematischen Ermordung von Menschen im Rahmen der „Euthanasie“, so auch mit der Aufarbeitung der NS-Zeit und gegenwärtigen Fragen der Inklusion stellt ein wichtiges Ziel eines inklusiven (Geschichts-)Unterrichtes dar. Die Masterarbeit setzt sich mit diesen Themen auseinander. Dazu werden die Theorien des Sozialdarwinismus und der Eugenik, die NS-„Euthanasie“ sowie gegenwärtige Diskurse um Teilhabe und Inklusion zunächst fachwissenschaftlich aufbereitet. Im empirischen Teil der Arbeit werden Geschichtsschulbücher der Sekundarstufe II anhand der „Kritischen Diskursanalyse“ nach Jäger untersucht, um festzustellen, wie diese Theorien und Diskurse in Geschichtsschulbüchern der 11. Schulstufe dargestellt und welche Normen und Werte darin an die Schüler*innen herangetragen werden. Die Analyse der Lehrwerke zeigt, dass sich ein Großteil der herausgearbeiteten Diskursfragmente den Repressalien von Menschen mit Behinderungen in der Zeit des Nationalsozialismus bzw. der NS-„Euthanasie“ widmet. Es werden nur sehr wenige Lebensgeschichten von Opfern oder ihren Angehörigen eingebracht. Der Sozialdarwinismus wird in der Mehrzahl der Schulbücher zum Thema gemacht. Ereignisse nach Ende des Zweiten Weltkrieges (Aufarbeitung der Morde, Erinnerungskultur, Rechte von Menschen mit Behinderungen) nehmen eine untergeordnete Rolle ein. Dies könnte durch die Thematisierung der Behindertenbewegung oder von offenen Forderungen zur Inklusion erreicht werden. Den Abschluss der Arbeit bildet die fachdidaktische Aufbereitung der Ergebnisse mittels Erstellung von Schulbuchseiten in Form eines Längsschnittes für die Praxis des Geschichtsunterrichts.

description: Coined discrete-time quantum walks are studied using simple deterministic dynamical systems as coins whose classical limit can range from being integrable to chaotic. It is shown that a Loschmidt echo like fidelity plays a central role and when the coin is chaotic this is approximately the characteristic function of a classical random walker. Thus the classical binomial distribution arises as a limit of the quantum walk and the walker exhibits diffusive growth before eventually becoming ballistic. The coin-walker entanglement growth is shown to be logarithmic in time as in the case of many-body localization and coupled kicked rotors, and saturates to a value that depends on the relative coin and walker space dimensions. In a coin dominated scenario, the chaos can thermalize the quantum walk to typical random states such that the entanglement saturates at the Haar averaged Page value, unlike in a walker dominated case when atypical states seem to be produced.

description: A school is a place that molds the individual in a very holistic manner. It is a training ground where students can develop, harness, and maximize their potentials to be a responsive and excellent man as a product of their learning process. Furthermore, this study aims to assess the respondents' perceptions of their school culture and its impact on their academic performance. The research method utilized in this study was a descriptive correlational approach. The respondents were 141 Grade 11 students from a Public School. Findings were statistically computed with linear regression analysis and concluded that the respondents’ perception of the school culture does not significantly affect their academic performance. Further, based on the findings of the study it concluded that (1) the school with its teachers keep them motivated and challenge them to do their best, (2) the rules and regulations implemented in their school are not punitive, (3) students who follow the rules and regulations perform better than those who do not, (4) the school activities are beneficial to the well-being for the students, (5) their assessment tests received from their teachers provides them preparedness and confidence towards their final examination, and (6) feedbacking from their teachers provide them ways on improving their academic performance. Moreover, the implications of the study were discussed, and recommendations were suggested.

description: We use the linear sigma model with quarks to locate the critical end point in the effective QCD phase diagram accounting for fluctuations in temperature and quark chemical potential. For this purpose, we use the non-equilibrium formalism provided by the superstatistics framework. We compute the effective potential in the high- and low-temperature approximations up to sixth order and include the contribution of ring diagrams to account for plasma screening effects. We fix the model parameters from relations between the thermal sigma and pion masses imposing a first order phase transition at zero temperature and a finite critical value for the baryon chemical potential that we take of order of the nucleon mass. We find that the CEP displacement due to fluctuations in temperature and/or quark chemical potential is almost negligible.

description: Eisenbahnbrücken erfahren bei Zugüberfahrten eine dynamische Anregung, die unter bestimmten Voraussetzungen zu einer übermäßigen Schwingungsantwort führen kann. Laut aktueller Normensituation ist daher unter gewissen Rahmenbedingungen eine dynamische Berechnung der Tragwerksantwort von Brückentragwerken durchzuführen. In der vorliegenden Arbeit wird ein normgerechtes Berechnungsverfahren vorgestellt, bei dem die Modalanalyse (als Spezialfall der Methode nach Ritz und Galerkin) Anwendung auf Einfeldträgerbrücken findet. Die betrachteten Zugkonfigurationen werden dabei als Folge von Einzellasten modelliert, die sich mit konstanter Geschwindigkeit über einen Brückenbalken bewegen. Die Ergebnisse dieses Berechnungsverfahrens werden in Form von Antwortspektren in einer Datenbank gespeichert. Der Hauptteil dieser Diplomarbeit befasst sich mit der Entwicklung und der Funktionsweise der Software DynZugVergleich, die zur Auswertung der Antwortspektren dient. Dieses Programm ermöglicht den Vergleich der dynamischen Tragwerksantwort von Einfeldträgerbrücken auf unterschiedliche Zugmodelle. Zusätzlich wird die Anwendung des Programms DynZugVergleich exemplarisch an einem realen Brückentragwerk gezeigt.
description: Trains cause dynamic excitations by crossing Railway bridges. Under certain circumstances, these excitations can lead to excessive vibrations of the structure. Due to the current state of European standards, the response of railway bridges to train crossings has to be determined by dynamic analysis, if specific parameters are complied. This master thesis introduces a calculation method consistent with European standards, that adapts the modal response spectrum analysis (as a specialized application of Ritz` and Galerkin's method) to simply supported girder systems. The vehicles are described as a series of forces, that move over the bridge girder with constant velocity. The results of the calculation method are combined in response spectrums and saved in a data base. The main part of this master thesis deals with the development and the functional principle of the software DynZugVergleich, that enables the evaluation of the response spectrums. This program provides the comparison of the dynamic response of simply supported girder bridges to different train models. Furthermore, the usage of DynZugVergleich is shown for an example of a real bridge structure.
title: Evaluation of Glutamatergic Treatment in Reducing Nicotine Seeking Behavior in Rats

description: Although pharmacotherapy and psychosocial support can help smokers to quit, the high relapse rates indicate a high unmet need for more effective treatment. Recent studies have highlighted changes in glutamate (GLU) homeostasis in the circuitry from the prefrontal cortex (PFC) to the nucleus accumbens (Nacc) as vital in the reinstatement of drug-seeking behavior. Restoring basal concentrations of extracellular GLU, thereby increasing tonic activation of the presynaptic group II metabotropic GLU receptors (mGluR2/3) by a single injection of N- acetylcysteine (N-AC) prevented cues-induced cocaine- and heroin-seeking behavior in rats. Although nicotine-associated cues reinstate drug-seeking by acting on GLU transmission in the Nacc it is still not clear whether N-AC can inhibit cue-induced reinstatement in abstinent rats after nicotine self-administration. It is also not clear whether chronic N-AC treatment could elicit an enduring reduction in cue-induced reinstatement.

 Rats were trained to associate discriminative stimuli (SDs) with intravenous nicotine vs. saline in two-lever operant cages. Reinforced response was followed by cue (CSs). Re-exposure to nicotine SD+/CS+, but not saline SD-/CS-, revived responding at the previously reinforced lever. A single dose of N-AC (100 mg/kg i.p.) increased extracellular GLU in the Nacc only in rats with an history of nicotine self-administration. Moreover, the same dose of N-AC induced a short-term reduction of cue-induced nicotine-seeking behavior that was completely prevented by pre-treatment with the selective mGluR2/3 antagonist LY341495 (1 mg/kg i.p.). Chronic treatment with N-AC (100 mg/kg) during 14 days of cues exposure therapy, induced long- lasting anti-relapse activity that was still present 50 days after the end of the treatment. To investigate the molecular mechanism in the Nacc underlying chronic N-AC effect, rats were killed at different time points. Western blot analysis revealed that 7 days after treatment, chronic N-AC restored the expression of proteins crucial for GLU homeostasis, while 51 days after treatment the expression of mGluR2 was increased only in chronic N-AC treated rats. Overall, the results of the Thesis suggest a potential therapeutic use of N-AC for cue-controlled nicotine-seeking behavior.

description: In this paper we consider in detail the composition of an irreducible polynomial with X^2 and suggest a recurrent construction of irreducible polynomials of fixed degree over finite fields of odd characteristics. More precisely, given an irreducible polynomial of degree n and order 2^rt with t odd, the construction produces ord_t(2)/d irreducible polynomials of degree n and order t for a certain divisor d of n. The construction can be used, for example, to search irreducible polynomials with specific requirements on its coefficients.

description: Late blight is one of the most destructive diseases causing severe yield losses of potato in Kashmir valley. So, In the present study, four different protectant fungicides (mancozeb 75 WP, chlorothalonil 75 WP propineb 70 WP) were evaluated at field level at three different concentrations (1.5%, 2% and 2.5%) by spraying at weekly intervals starting from symptom exhibition to the ten days before dehaulming stage during cropping seasons 2016 and 2017. With this study, it was found that all the fungicides (mancozeb, propineb and chlorothalonil) were equally superior to control (water spray) in reducing the blight incidence from 75.55 to 31.03 per cent. There existed a significant interaction between fungicides and their concentrations. All the three test fungicides at C1-C3 concentration reduced the disease incidence to 24.44-51.17 per cent from 75.55 per cent observed in water sprayed check. Mancozeb 75WP was highly effective in reducing the late blight disease with a least mean disease intensity, incidence and area under disease progress curve(A value) values of 15.07,31.10 and 82.48% respectively at all the test concentrations followed by propineb 70WP and chlorothalonil 75WP, whereas highest amount of disease development was recorded in control (water spray), with mean disease intensity, incidence and AUDPC values of 55.39%, 77.77% and 292.34% respectively during the season 2016. Similar trend of results were obtained during the season 2017 where mancozeb showed highest efficacy against late blight disease with mean disease intensity, incidence and AUDPC values of 15.74%, 31.03% and 84.83% followed by propineb 70 WP and chlorothalonil 75 WP compared to control (water spray) where disease intensity, incidence and AUDPC values were recorded as 53.24%, 75.55% and 293.24% respectively. Apart from the disease control, highest tuber yield and marketable (grade A&B) tuber percent were also recorded in the treatment with mancozeb followed by propineb 70WP and chlorothalonil 75WP, whereas lowest tuber yield and unmarketable tubers (grade C) were recorded in control (water spray) treatment during cropping seasons of 2016 and 2017.

description: The main aim of the article was to present chosen aspects of the economic situation of individual farms’ sector in Poland as compared with the situation observed in the EU in 2000-2005. A special emphasis was put on the agrarian, productive and income situation in sector. Comparisons of Poland and other EU countries lead to a conclusion that Poland has a huge agricultural potential, but this potential is not taken advantage of. It’s main feature is a high diversity betwen regions. The most important problems observed in the sector are: inappropriate agrarian structure, superflous employment, low level of specialization and commercialisation of farms, disadvantageous structure of sources of agricultural income in family farms, lack of capital. A comparison of average economic results in Polish and other European farms in 2004 based on the European accountancy data allows to formulate a conclusion that most of the selected economic indices are approximately 3 times lower in an average Polish farm than in an average farm in the EU member states. / Synopsis. W artykule podjęto próbę przedstawienia wybranych aspektów sytuacji ekonomicznej sektora indywidualnych gospodarstw rolnych w Polsce na tle Unii Europejskiej w latach 2000-2005, ze szczególnym uwzględnieniem sytuacji agrarnej, produkcyjnej i dochodowej w sektorze. Porównania Polski z krajami UE wykazują, że Polska jest krajem o znacznym potencjale rolnictwa. Do najtrudniejszych problemów w sektorze można zaliczyć: niekorzystną strukturę agrarną, przerost zatrudnienia, niski stopień specjalizacji gospodarstw, niski udział gospodarstw towarowych, niekorzystną strukturę źródeł dochodów rolniczych w indywidualnych gospodarstwach rolnych, niedostatek nowoczesnego kapitału. Porównanie średnich wyników gospodarstwa rolnego polskiego i unijnego w 2004 roku w ramach rachunkowości unijnej pokazuje, że większość wybranych kategorii ekonomicznych była około 3-krotnie niższa w polskim przeciętnym gospodarstwie niż w unijnym.

description: The aim of the paper is to present the influence of EU enlargement on food consumption level and on the raw agricultural products prices in Poland. The analysis of consumption level of selected food products asserts that trends have been continued since the 90s. and Polish accession to the EU has not changed them. Raw agricultural products prices in the common market have become more equalized since the EU enlargement. / Synopsis. W artykule przedstawiono wpływ rozszerzenia Unii Europejskiej na poziom konsumpcji żywności w Polsce oraz na ceny surowców rolniczych w kraju. Analiza poziomu konsumpcji wybranych artykułów żywnościowych pokazała, że dotychczasowe trendy są kontynuowane od początku lat dziewięćdziesiątych, a akcesja Polski do Unii Europejskiej nie miała na nie wpływu. Rozszerzenie Unii spowodowało, że ceny surowców rolniczych wyrównują się wewnątrz wspólnoty.

description: We present an algorithm based on maximum likelihood for the estimation and renormalization (marginalization) of exponential densities. The moment-matching problem resulting from the maximization of the likelihood is solved as an optimization problem using the Levenberg-Marquardt algorithm. In the case of renormalization, the moments needed to set up the moment-matching problem are evaluated using Swendsen's renormalization method. We focus on the renormalization version of the algorithm, where we demonstrate its use by computing the critical temperature of the two-dimensional Ising model. Possible applications of the algorithm are discussed.

description: This study aims to investigate the influence of personality traits on the academic achievement of the Senior High School at St. Paul College of Bocaue. This study used the descriptive-correlation research method that utilized a standardized instrument as a primary data gathering tool. The respondents of the study were the Grade 11 Senior High School students at St. Paul College of Bocaue. The result of the study showed that the “Big Five” personality traits of the students were at an extreme level. Likewise, the result suggests that the students are very creative, focused on tackling new challenges, pays attention to detail, likes to be the center of attention, likes to meet new people, feels empathy and concern for other people. Moreover, the students experience a lot of stress, worry about many different things and feel anxious about their environment. Furthermore, the null hypothesis was tested at the 0.05 alpha level of significance to determine the impact of personality on the academic achievement of the students. The computed multiple regression analysis results revealed that personality traits do not significantly affect the academic achievement of the students.
