Фотосенсибилизированный синглетный кислород и кислородные комплексы в возникновении и изменении пространственно-неоднородной люминесценции в растворах антрахинона
Authors: Карицкая С.Г.
Published: December 2019

Основное содержание исследования составляет анализ процессов, приводящих к неоднородной по пространству и времени люминесценции (к так называемым люминесцирующим пространственновременным структурам), наблюдаемой в видимой области (lmax= 490 нм) при ультрафиолетовом (УФ) облучении антрахинона в насыщенных кислородом растворах и в полимерных матрицах. Экспериментально регистрируемая люминесценция приписывается фотопродукту: кетильному радикалу антрахинона, чья концентрация в ходе инициируемых УФ излучением фотохимических реакций периодически возрастает и убывает в различных и разрозненных точках реакционного пространства. В работе обоснована значимость реакции тушения триплетных состояний молекул антрахинона кислородом О2(3Σ-g ), обсуждена возможность генерации синглетного кислорода O2(1Δg) на больших расстояниях от реакционного центра вследствие переноса электронно-колебательного возбуждения на молекулу растворителя и подчеркнута существенная роль сенсибилизированного синглетного кислорода в перераспределении концентраций реагентов и фотопродуктов. Предложена модель возникновения и развития пространственно-неоднородной люминесценции растворов антрахинона, включающая фотосенсибилизированное образование синглетного кислорода и диффузию кислородных комплексов с молекулами растворителя. Главное достоинство предлагаемой модели, учитывающей возникновение и присутствие именно синглетного кислорода O2(1Δg), — возможность не только объяснить экспериментально наблюдаемые эффекты возникновения и развития пространственновременных структур, но и предсказать условия изменения, характер поведения начальной стадии их развития и конечный результат. Обсуждаемая в работе зависимость феномена от концентрации растворенного кислорода может найти применение в сенсорных приложениях.

L’objectif de cette étude est d'examiner l'effet du programme d’'Erasmus et du carnet de voyage sur le développement de la sensibilité interculturelle (SI) des futurs enseignants de langues. L’échantillon de cette étude est composé des futurs enseignants de langues (anglais, français, allemand ; Université Anadolu) ayant participé au programme Erasmus et de leurs camarades de classe. L'échelle de la SI développée par Chen et Starosta a été appliquée au début et à la fin du semestre. Les résultats ont montré que les étudiants d’Erasmus sans carnet de voyage ont augmenté leur niveau de sensibilité au contraire des apprenants ayant préparé un carnet de voyage. Les résultats du prétest et du posttest des deux groupes ne sont pas statistiquement significatifs. Selon l’analyse des niveaux de sensibilité des 33 étudiants (groupe expérimental) ayant participé à Erasmus et des 33 étudiants n’ayant pas participé (groupe témoin), le niveau de sensibilité du groupe expérimental est plus élevé au début et à la fin du semestre. Cependant, il n'y a pas de différence significative entre les résultats du prétest et posttest.

situation
Authors: Mon Ei Ei , Vasupongayya Sangsuree , Karnjanadecha Montri , Angchuan Touchai
Published: December 2019

Biometric template protection approaches have been developed to secure the biometric templates against image reconstruction on the stored templates. Two cancellable fingerprint template protection approaches namely minutiae-based bit-string cancellable fingerprint template and modified minutiae-based bit-string cancellable fingerprint template, are selected to be evaluated. Both approaches include the geometric information of the fingerprint into the extracted minutiae. Six modified fingerprint data sets are derived from the original fingerprint images in FVC2002DB1_B and FVC2002DB2_B by conducting the rotation and changing the quality of original fingerprint images according to the environment conditions during an emergency situation such as wet or dry fingers and disoriented angle of fingerprint images. The experimental results show that the modified minutiae-based bit-string cancellable fingerprint template performs well on all conditions during an emergency situation by achieving the matching accuracy between 83% and 100% on FVC2002DB1_B data set and between 99% and 100% on FVC2002DB2_B data set.

Published: December 2019

Sleep apnea is the cessation of airflow at least 10 seconds and it is the type of breathing disorder in which breathing stops at the time of sleeping. The proposed model uses type 4 sleep study which focuses more on portability and the reduction of the signals. The main limitations of type 1 full night polysomnography are time consuming and it requires much space for sleep recording such as sleep lab comparing to type 4 sleep studies. The detection of sleep apnea using deep convolutional neural network model based on SPO2 sensor is the valid alternative for efficient polysomnography and it is portable and cost effective. The total number of samples from SPO2 sensors of 50 patients that is used in this study is 190,000. The performance of the overall accuracy of sleep apnea detection is 91.3085% with the loss rate of 2.3 using cross entropy cost function using deep convolutional neural network.
A graph-based algorithm for interpersonal ties clustering in signed
networks
Authors: Sangamuang Sumalee
Published: December 2019

Social ties are formed as a result of interactions and individual preferences of the people in a social network. There are two opposite types which are interpreted as friendship vs. enmity or trust vs. distrust between people. The aforementioned social network structure can be represented by a signed graph, where people are the graph’s vertices and their interactions are graph’s edges. The edges can be positive and negative signs. To determine trustworthiness, this paper considers the problem of a signed graph partitioning with minimizing the sum of the negative edge's weight and balanced size of its clusters. An efficient algorithm to solve such a problem is proposed. The experimental results show that the proposed algorithm outperforms in terms of the execution times and the accuracy within the given bounds.
The empirical study: encouraging students’ interest in software
development using test-driven development
Authors: Nanthaamornphong Aziz , Bressan Stephane
Published: December 2019

The supply is not matching the demand on the market for software developers. While the enrolment in undergraduate computer science courses is increasing, few students are interested in and committed to becoming software developers. It could be that students are overwhelmed by the software development methodology that they are taught. We are consequently looking for a constructivist approach to software engineering able to effectively engage learners. We empirically evaluated whether test-driven development (TDD) is able to improve the quality of both learning and of software development in the classroom. Although numerous studies have outlined the benefits and effects of TDD in the classroom, none of those studies have focused on measuring students' interest in and attitudes toward using TDD in the classroom. We present a study evaluating the impact of TDD on the engagement and focus of learners of software development in the classroom. The results illustrate that the use of TDD in the classroom encourages learners to engage and focus.

Published: December 2019

Conflicts between different interests are inevitable in every business organization. Therefore, it is not surprising that the number and intensity of conflicts is sometimes very high. Conflict resolution is a skill without which managers can hardly succeed in their business. The subject of research in this paper is conflict management from a technical and economic point of view. The paper defines and analyzes the notion of leadership, that is, elements and dimensions of leadership, the notion of leader, and theoretical approaches to leadership. In addition to the above, the concept of conflict, more specifically its type, levels of conflict, consequences and causes, and techniques of conflict resolution have been defined and analyzed. An online survey (based on the LinkedIn Business Social Network) was conducted to determine how individuals in a production organization respond and resolve conflicts as well as the results of the same. Based on theoretical scientific approach, the conducted research and the analysis of the results, conclusions and recommendations are given, as well as key questions for future research.

The Synthesis of the Traditional and the Innovative as the Main Direction for Mastering Chamber and Ensemble Instrumental Creativity by Mechislav Weinberg in the University Musician Training
Authors: Boiko Valentina L. , Chaykin Sergey G.
Published: December 2019

2019 is declared the Mieczyslaw Weinberg’s year due to the 100th anniversary of the composer’s birth, whose works are rarely heard in concert halls of Russia. This fact stipulated the current paper devoted to Weinberg’s works. The study is intended to contribute to the composer’s profile and to add some pedagogical and performing observations and recommendations. A number of special methods of analysis of musical works (structural, harmonic, etc.) are used in the paper, as well as a system approach to the theoretical insight into the process of integration Weinberg’s chamber and ensemble compositions into the professional musical training. Artist and time, composer and performer, musical and artistic interpretation – these are the categories musical and performing arts deal with. In this paper, we focus on the chamber-instrumental genre and, in particular, Weinberg’s Sonata for violin and piano A-dur op. 37 No. 3 to examine the peculiarities of the composer’s musical language. The article indicates the conditions that are essential to solve the tasks performers often face – comprehension of Weinberg’s chamber and ensemble instrumental works’ inherent features, getting the most complete revealing of musical and artistic imagery of his compositions, defining distinguishing features of ensemble performing. Following the state educational standards in the field of training instrumental musicians to meet high-level proficiency requirements, the authors examine synthesis of tradition and innovation in the composer’s chamber ensemble instrumental works, provide deep analysis of a composition that is recognized as a piece of high aesthetic and ethical value. Thus, the authors believe it to be an appropriate work to contribute to the professional and spiritual growth of everyone who turns to this music, including young musicians engaged in chamber ensemble.
Author’s Comments in the Conceptual Space of Musical Text: to the Methodology of Research of Musician Teacher
Authors: Malinkowskaya Augusta V.
Published: December 2019

This article presents the problem of the relationship between two landmark subsystems in the conceptual space of the musical composition text: notation and author’s instructions, comments of various types and functions. The author contrasts the text formal division (it is used in performing and pedagogical practice, non-binding “notes” and instructions by the composer of minor importance) and views of musicians who see in the traditional dichotomy “musical text – comments on it” a theoretical problem. The differences in approaches to it are analyzed in the works by S. E. Feinberg, E. Ya. Liberman; it is proposed to consider the position of the author of the article, treating the first of these subsystems as a base, the second as a superstructure in a united conceptual space of a musical text. The author develops the theme and carries out historical-style excursions and reveals the evolution of the composer’s comments in the music in 17th – early 20th centuries due to aesthetic, artistic, technological and other factors. In the historical-style sections of the article, the author relies on the concept by S. S. Skrebkov, that is in the book “The Artistic Principles of Musical Styles”. In particular, the author uses the principle of centralizing unity postulated by the scientist as a methodological guide, and interpreted broadly in the article as a general dialectical principle of musical logic. This allows to differ stylistically and at the same time to study dialectically the practice of composer commentary in musical works of the Baroque, classical and romantic eras. The main conclusion of the article is the reference to the need for performers and teachers to deepen into essential, substantial relations in a united conceptual space of a musical text of two main plans: notated, reflecting introverted, immanently musical meaning, and composer comments, where denotation is carried out, symbolization of the deep structures of music.
Recent trends in fish feed ingredients – mini review
Authors: Révész Norbert , Biró Janka
Published: December 2019

Fish farming is commonly described as being extensive, semi-intensive or intensive. The continuous growing of aquaculture sector (around 8 % per year) led systems to be more and more intensive. In intensive farming, the fish are kept at high stocking density, that’s why the fish are dependent on the feed provided. Last decades aquaculture became more and more effective, but it has not been without concern for natural resource use, environmental impact and social judgement. Increasing fishmeal (FM) cost, irregular supply, decreasing availability, and poor quality of FM have put forward highlighting on its partial or complete substitution with other alternative protein sources. The fish feed industry has to be very responsible about to use FM alternatives. Scientists have to share on this burden to achieve sustainable, cost-effective aims. Indicators of sustainability in aquaculture could be energy efficiency, use of water, nutrient utilisation efficiency and production costs. The climate change is also affecting the sector, such as the predicted changes in ocean circulation pattern might also have a negative influence on the reliability of small pelagic stocks that being utilized for FM production or the appearance of mycotoxins on terrestrial plants, what could be possible alternative ingredients. The increase of the amount of non-marine ingredients in feeds is the result of years of investment and research in feed formulation to provide the nutrients the fish need to growth and remain healthy. Significant progress has been made over the past decade in reducing levels of FM in commercial feeds for farmed fish. Common obstacles associated with consumption of plant-based protein diets, because many times we face the facts with amino acid imbalances and deficiencies, high levels of indigestible carbohydrates present in certain grain products, and varying antinutritive factors (ANFs) that negatively affect fish growth and health. In this study the recent trends in alternative fish feed ingredients had been reviewed shortly. In conclusion, complete replacement of fishmeal in fish feeds is more difficult and will require further research efforts to achieve the expected goals, but there are many auspicious alternatives.

Published: December 2019

Diseases, particularly bacterial wilt caused by Ralstonia solanacearum is a major constraint to vegetable production. Protected cultivation has been proven effective in reducing disease incidence but additional control measures need to be integrated in highly infested soils to mitigate the losses due to diseases. This paper reports the effect of resistance elicitors, particularly chitosan, acetylsalicylic acid and SiO2 in mitigating bacterial wilt disease problem and other naturally occurring diseases in two field trials. Two hundred ppm chitosan, acetylsalicylic acid and their combination had reduced bacterial wilt incidence and increased the yield of tomato under protected cultivation, but not in the open field. SiO2 was not able to reduce bacterial wilt incidence in tomato but had reduced the nematode count, especially Rotylenchulus sp. in the roots, particularly when drenched. Protected cultivation still proved effective in reducing bacterial wilt incidence in both experiments. It’s potential to protect crops against bacterial wilt is further enhanced by the application of chitosan and acetylsalicylic acid, most especially the combination of these treatments. The potential of chitosan and acetylsalicylic acid in protecting plants in the open field against bacterial wilt may be enhanced by the addition of a sticker.

Природні зміни рослинності долини лиману репрезентовані сингенетичними (первинними та вторинними), ендоекогенетичними та екзоекогенетичними, зокрема специфічними для схилових територій геоморфогенними сукцесійними рядами. Значний розвиток процеси сингенезу та ендоекоґенезу отримали у останні десятиріччя внаслідок катастрофічного зменшення акваторії лиману і утворення значних за площами нових територій. На первинних етапах заростання вони колонізуються піонерними галофітами, які започатковують сукцесійний ряд від агломерацій Salicornia perennans – до угруповань засолених лук асоціації Artemisietum santonicae. У роботі висвітлюються особливості первинних сукцесій рослинності, що відбуваються на різних територіях узбережжя лиману. Вторинне заростання кар’єрів на лиманних косах та прибережних територій, рослинний покрив яких був знищений внаслідок меліоративних робіт, відбувається за участі рудеральних видів, серед яких багато адвентивних. Природна рослинність цих територій в сучасних умовах не поновлюється. Геоморфогенні сукцесії рослинності пов’язані з рухливістю субстрату на зсувних ділянках схилів долини. Вони мають надзвичайно сильний вплив на формування степової рослинності на цих територіях. Найпоширенішими є уповільнені регресивні геоморфогенні зміни, які призводять до заміщення зональних степових угруповань пустельно-степовими та галофітно-степовими. Катастрофічні геоморфогенні зміни характерні для дуже крутих глинистих та лесових схилів. Відновлення рослинності на осипах починається з бур’янових стадій і проходить у напрямку формування степових та чагарникових угруповань.

Authors: Correa Ospina Jenny Paola , Cardona Santa María Camila , Gómez Rodas Alejandro
Published: December 2019

Introducción: la natación es una actividad que genera una alta prevalencia de lesiones de hombro, debido a la cantidad de movimientos repetitivos y a la ausencia de tiempo de descanso; la debilidad, la posición anormal, y la sincronización anormal de los músculos tanto del hombro como de la cintura escapular, han sido asociados a disfunciones del movimiento que puedenconducir a alteraciones funcionales, finalización de la participación deportiva y discapacidad, por esto se hace necesario indagar sobre el balance de la fuerza isométrica del hombro en nadadores del Club Flamingo de natación de la ciudad de Pereira.

Método: estudio no experimental-descriptivo, de tipo empírico analítico y de carácter observacional analítico; la población de la investigación se constituyó por 19 nadadores pertenecientes al Club Flamingo de natación de la ciudad de Pereira de las categorías juvenil 1-2 (13 -17 años) y mayores (18 años en adelante). Se realizó un análisis univariado descriptivo con una segunda fase inferencial para determinar diferencias por género, tanto en la fuerza muscular de los músculos del hombro como por su dominancia lateral.

Resultados: se encontró una media para la edad en hombres y mujeres de 18 ± 4,1 y 17,1 ± 4,3 años respectivamente, un índice de masa corporal de 22,8 ± 2 Kg/m2 y 22,2 ± 1,1, Kg/m2 en hombres y en mujeres, con un porcentaje graso de 18,2% ± 6,2 y 29,9% ± 3,2 tanto en hombres como en mujeres. No se encontraron diferencias significativas en la fuerza muscular isométrica del hombro entre hombres y mujeres, como tampoco entre miembro superior dominante y no dominante (p > 0,05). La fuerza muscular isométrica de cada músculo del hombro conserva un patrón especifico similar a lo encontrado en otros estudios.

Conclusión: en esta muestra de nadadores no existen diferencias en la fuerza muscular isométrica del hombro por género y dominancia lateral. Se observó un patrón de fuerza muscular similar a lo encontrado en otros estudios.

Published: December 2019

Objectives: Glomerular Filtration Rate (GFR) is an important parameter of kidney function. Many methods are used to measure GFR namely: inulin clearance, double plasma sample method (DPSM), Gates’ method, and equation based method. DPSM has become the gold standard in clinical research. Gates’ method is routinely practiced at National Institute of Nuclear Medicine and Allied Sciences. Chronic kidney disease epidemiology collaboration (CKD-EPI ) equation is encouraged as it is simple and reliable. The aim of the study was assesment of agreement between Gates’ method and CKD-EPI equation with plasma sample method for estimation of GFR.

Patients and methods: This cross sectional observational study was carried out at NINMAS, during July 2017 to June 2018. A total of 70 subjects referred for 99mTC-DTPA renography along with GFR estimation, were included in this study.

Result: The mean GFR value evaluated by DPSM, Gates’ and CKD-EPI  equation were, 81.86 ± 22.42, 86.13 ± 26.70 and 78.48 ± 23.87 mL/min/1.73 m2 respectively. A strong positive correlation (r = 0.922) was found between DPSM and Gates’ method and also between DPSM and CKD-EPI equation (r= 0.930). The Gates’ and CKD-EPI equation also showed strong positive correlation (r = 0.872). The mean difference between DPSM and Gates’, between DPSM and CKD-EPI equation,  between Gates’ and CKD-EPI equation were 4.26 ± 10.45, 3.38 ± 8.78  and  7.64 ± 13.09 mL/min/1.73 m2 respectively.

Conclusion: Strong positive correlation and excellent agreement were observed between DPSM and Gates’ and also between DPSM and CKD-EPI equation. Strong correlation was also found in between Gates’ and CKD-EPI equation. So, DPSM, Gates’ method and CKD-EPI equation can reflect GFR almost equally and used interchangeably.

Objective: Worldwide, osteoporosis in postmenopausal women is a common public health problem. The measurement of bone mineral density (BMD) of spine and hip using central dual energy X-ray absorptiometry (DXA) is the most standard technique to diagnose osteoporosis. But in many circumstances, measurement of spine or hip BMD is quite difficult to carry out where wrist BMD can be used as an alternative. Moreover, wrist BMD can be done with smaller, cheaper, portable peripheral devices for screening osteoporosis at primary health care level. The objective of the study was to explore the agreement of wrist BMD with spine and hip BMD in postmenopausal women.

Patients and Methods: This observational, cross sectional study was carried out at National Institute of Nuclear Medicine & Allied Sciences (NINMAS), Bangabandhu Sheikh Mujib Medical University (BSMMU) campus, from July 2017 to June 2018. A total of 110 postmenopausal women referred to NINMAS for BMD measurement were enrolled in this study after fulfilling selection criteria.  BMD of spine, right and left hip and wrist of enrolled subjects were measured by dual energy X-ray absorptiometry (DXA) scan by Stratos DR Bone densitometer.

Results:  Agreement analysis done by kappa statistics revealed kappa value of 0.930 (p<0.05), 0.782 (p<0.05) and 0.635 (p<0.05) between wrist and spine BMD, wrist and right hip BMD and wrist and left hip BMD, respectively. In Bland-Altman analysis, the mean difference of T-score measured by wrist and spine was -0.007 ± 1.361, wrist and right hip was -0.645 ± 1.271 and wrist and left hip was -0.450 ± 1.259 with 95% of differences were found in between -2.674 and 2.660, -3.136 and 1.846 and -2.917 and 2.017, respectively. Positive significant Pearson’s correlation was observed between wrist BMD and spine BMD (r=0.664; p=0.001), wrist BMD and right hip BMD (r=0.719; p=0.001) and wrist BMD and left hip BMD (r=0.727; p=0.001).

Conclusion: This study results showed an excellent kappa agreement between wrist and spine BMD with good kappa agreement of wrist with right and left hip BMD as well as in Bland-Altman analysis, the mean differences of T-score between wrist andspine, wrist and right hip and wrist and left hip were small. The biases between the methods were considered not significant suggesting that these sites can be used interchangeably for measurement of BMD. Hence, wrist BMD can be used with regular skeletal sites (spine and hip) as an effective method of diagnosing osteopenia and osteoporosis by DXA where spine or hip BMD is difficult to carry out as well as it can be used for osteoporosis screening at primary health care level by portable peripheral DXA device to initiate early treatment to reduce fracture risks.

Serum Vitamin D Status in Newly Diagnosed Hypothyroid Patients
Authors: Khan Naheed , Sultana Sadia , Mou Madhuchhanda Hazra , Sarmin Suraya
Published: December 2019

More than billion people worldwide are vitamin D deficient. It is recognized to have function in bone and muscle development by regulating calcium and phosphorus metabolism. Its role as an immune modulator has recently been discovered. Deficiency of vitamin D has been discovered to be associated with various cardiovascular, infectious, malignant, hypothyroidism and autoimmune thyroid diseases. Prevalence of hypothyroidism and hypovitaminosis D in Bangladesh is not known but supposed to be high because our neighbor country India has high prevalence. Vitamin D mediates its effect through binding to vitamin D receptor (VDR) and activation of VDR- responsive genes. VDR gene polymorphism was found to be associated with autoimmune thyroid diseases. On the other way hypothyroidism either decreases the metabolism of vitamin D or prevents to activate it. A total of 38 adult hypothyroid otherwise healthy patients and age, sex, BMI, socioeconomic status matched euthyroid adults were included in the study. The mean age in the hypothyroid group was 37.82 ± 7.95 years and in the euthyroid group was 34.84 ± 8.61 years. Male participants were14 and female participants were 24 in each group. The mean value of serum vitamin D of healthy group was 17.11 ± 5.62 ng/ml  and in hypothyroid patients was 13.16 ± 4.29 ng/ml., Hypothyroid patients had significantly lower levels of serum Vitamin D3 as compared to controls (p =0.037,<0.05). Negative correlation was observed between serum TSH and serum vitamin D (r=-.119, p=.034), moderate positive correlation was observed between serum FT4 and serum vitamin D ((r=0.457, p=0.01, P<0.05).

Contemporary approaches to working with a family educating a child with speech disturbance
Authors: Lastochkina Yelena , Liannaya Olga , Litvinenko Vitalina
Published: December 2019

The following article presents speech-therapy guidance for the families, who have kids with speech disorders, and outlines directions and means of solving the problem.
The authors view speech-therapy guidance as interaction of all the participants in the correction process.
Its implementation goes as a simultaneous, coherent system of work, which begins with interaction between the child, the therapist and experts in other specialties (psychologist, doctors, and rehabilitation specialists). Afterwards the work is meant to continue by parents supervised by the speech therapist.
The article touches upon both group and individual work done in cooperation with parents. Group work – parents’ meetings, guidance, round tables, exhibitions, seminars, frontal-work lessons, workshops, games and exercises’ libraries, visual libraries, open days and conferences. Individual work – individual discourses, practicing,
watching individual lessons, recommendation notices, homework notebooks, conducting surveys and home libraries.
The authors claim that the system of a speech-therapy guidance can be introduced as two general aspects in work:
1) Speech-therapy aspect involves acquiring knowledge about phases and peculiarities of the child’s speech development, enhancing speaking communication among children, forming awareness of pre-school children speech disorders, motivation for cooperation with speech therapists, teachers and children, acquiring skills to
follow the therapist’s advice and use all the correction exercises. The points mentioned above help to do the speech therapist supervised correction work, to adhere to the same requirements and the sequence of speech influence and conduct systematic correction work in accordance to the speech therapist’s advice.
2) Psychological aspect involves forming the knowledge about age-based psychological peculiarities of children’s development, fostering motivation skills for speaking communication, developing the skill of providing appropriate conditions for effective speech development, promoting ways of successful communication of children
and parents.
Nowadays there are different ways and forms of speech-therapy guidance for parents. The ones that proved to be the most informative and interactive are contemporary information technologies.
Korkeakoulujen opiskelijavalintauudistus ja aikuisopiskelijan opiskelumahdollisuudet
Authors: Haltia Nina , Isopahkala-Bouret Ulpukka , Jauhiainen Annukka
Published: December 2019

Tarkastelemme artikkelissamme 2010-luvulla toteutettua korkeakoulujen opiskelijavalintauudistusta aikuisopiskelijan opiskelumahdollisuuksien näkökulmasta. Empiirinen aineisto koostuu keskeisistä opiskelijavalintauudistukseen liittyneistä koulutuspolitiikkadokumenteista.

Analyysi etenee kaksivaiheisesti. Analysoimme ensin uudistuksen eri vaiheita ja toiseksi sitä, millaiseksi aikuisten paikka niissä diskursiivisesti rakentuu. Tunnistamme kolme keskeistä toimea, joiden avulla opiskelijavalintauudistusta on viety eteenpäin: 1) valtakunnallisen hakujärjestelmän luominen, 2) hakijoiden kiintiöinnit ja ensikertalaiskiintiön luominen sekä 3) valintakriteereiden muutos ja ylioppilastutkinnon painottaminen valinnoissa.

Argumenttimme on, että kaikki nämä toimet asettavat tutkintokoulutukseen pyrkivät aikuiset korkeakoulutuksen marginaaliin. Tulkitsemme löydöksiämme koulutuksellisen tasa-arvon valossa ja väitämme, että tärkeä ulottuvuus aikuisopiskelun suhteen on niin kutsuttu panosten reiluus. Tästä näkökulmasta korkeakoulutukseen pääsyn avoimuus eri-ikäisille on yhteiskunnallisesti tärkeä asia, ei vain aikuisten kannalta vaan siksikin, että sisäänpääsymahdollisuuksien olemassaolo pitää laajemmin yllä koulutusjärjestelmän oikeudenmukaisuutta. Aikuisten opiskelumahdollisuudet viestivät siitä, että yhteiskunnassa on mahdollisuus vaikuttaa omaan elämään ja sen suuntaan vielä nuorena tehtyjen valintojen jälkeenkin.
Työkulttuurien jännitteitä koulutusyhteisöissä

Tarkastelemme artikkelissa jännitteitä koulutusyhteisöjen työkulttuureissa. Lähestymme aihetta opettajankoulutuksen kehittämiseen orientoituneesta koulutusmallista valmistuneiden opettajien kokemusten avulla. Tutkimuksen empiirisenä aineistona on 13 puolistrukturoitua yksilöhaastattelua, jotka kerättiin koulutusmalliin osallistuneilta opettajilta. Teoriasidonnaisessa sisällönanalyysissa keskityttiin yhteisön työkulttuuriin etsien myös sen vaikeammin havaittavia elementtejä, Scheinin (2017) sanoin perusolettamuksia.

Tarkastelemme, miten yhteisöllisen ja kriittistä ammatillisuutta tukevan koulutusmallin anti on koettu ja miten sen vaikutukset ovat näyttäytyneet työelämässä. Tutkimuksemme nostaa keskiöön koulutuksen tuoman osaamisen ja työelämän käytäntöjen välisiä jännitteitä ja ristiriitoja. Merkitykselliseksi koettiin etenkin pitkäkestoinen ryhmäprosessi, joka on auttanut tiedostamaan koulutusyhteisöjen sosiaalisesti rakentuvia merkityksiä. Niiden havaitseminen, saati muuttaminen, on kuitenkin vaikeaa. Opinnoissa omaksuttu yhteisöllinen työkulttuuri opetti havainnoimaan ryhmien ja yhteisön dynamiikkaa myös työelämässä, tarkastelemaan koulukulttuuria kriittisesti ja kaipaamaan ammatillista keskustelua.

Työkulttuurien erilaisten toimintamekanismien vuoksi ajatuksia ammatillisuudesta oli vaikea toteuttaa koulukulttuurissa. Koulutus voi tehdä niistä tietoiseksi, mutta tietoisuus aiheuttaa törmäyksiä työelämässä. Koulutustutkimus hyötyisi ryhmien ja yhteisöjen sekä niihin kuulumisen, liittymisen ja niissä työskentelyn syvärakenteiden tarkastelusta.
