Voice, Perspective, Truth, and Justice: Race and the Mountain in the Legal Academy

Sedan tidigt 90-tal har det pågått en diskussion om den evidensbaserade praktikens vara eller inte vara inom socialtjänsten. Evidensbaserad praktik är en metod där den bästa tillgängliga evidensen, den egna erfarenheten samt klientens preferenser utgör grunden för professionella beslut. För att möjliggöra en sådan praktik måste bedömningar och dokumentation inom socialtjänsten utföras mer standardiserat. Förespråkarna, däribland Socialstyrelsen, menar att arbetets och insatsers effekt måste kunna mätas för att förbättras. Importen av evidensbaserad praktik i socialtjänst är dock förknippat med en rad svårigheter och vissa menar att det är ett hot mot de professioner som finns inom det sociala arbetet. Syftet med denna studie är att undersöka vilken inställning yrkesverksamma socialsekreterare har till evidensbaserad praktik. I det här arbetet utgår vi ifrån Lipskys gräsrotsbyråkrati för att undersöka socialsekreterarnas inställning. Teorin ger möjlighet att förklara organisationers beteende utifrån enskilda socialsekreterares yrkesutövning och inställningar. Studien är kvantitativ och data har samlats in via en enkät. Fyra socialkontor deltog i studien, tre från Stockholm och ett från Katrineholm. Totalt besvarade 67 socialsekreterare enkäten och resultaten från undersökningen är ganska lika resultat från tidigare forskning. Resultatet blev en ganska tydlig positiv inställning till evidensbaserad praktik, eller åtminstone till delar av evidensbaserad praktik. En möjlig förklaring till detta är socialsekreterarnas upplevda arbetsbelastning, där hög arbetsbelastning ger en mer positiv inställning till evidensbaserad praktik

Prediction of women''''s aesthetic belief in art based on the need for cognition and problem-solving styles with the mediating role of cultural intelligence

Examining aesthetic belief and artistic understanding is considered one of the important topics in art fields. The purpose of the current research was to investigate the relationship between aesthetic belief and problem-solving cognitive style and the need to recognize the mediating role of cultural intelligence in art students. Therefore, the main question of this research was whether it is possible to develop a model for women''s belief in artistic aesthetics based on problem solving styles and the need for recognition through the mediation of cultural intelligence? The research method is descriptive and correlational. The statistical population of this research included all female art students of Hamadan universities in the academic year of 2019-2019. 377 students were selected as a purposeful and available sample from among the faculties and educational groups and according to the research plan, and according to the aesthetic belief questionnaires of Taghizadeh and Babaei (2016), the need to know ( Cacioppo, Petty and Kao (1984), problem-solving styles Cassidy and Long (2013) and cultural intelligence Early and Ang (2003) answered. Research data with descriptive statistics (mean, standard deviation and skewness and skewness statistics) variables) and inferential statistics (Pearson''s correlation and path analysis with the calculation of its defaults) were analyzed. The results showed that the conceptual model compiled with the data had a good fit. The results of the structural relationships of the model showed that the aesthetic belief There is a positive and significant relationship with the constructive skill of problem solving, the need for recognition and cultural intelligence. The constructive skill of problem solving and the need for recognition have a positive and significant relationship with cultural intelligence. The non-constructive skill of problem solving has a negative and significant relationship with the need for recognition and cultural intelligence. Aesthetic belief has a negative and significant relationship with non-constructive problem-solving skills

Explanation women's Artistic Sketches based on Scientific Epistemological Beliefs with the role of Cognitive Load mediator in Architectural Design Education

The design process in architecture is one of the curricula of the field of architecture that is taught at different educational levels. For optimal educational planning, it is necessary to identify the variables related to it. Among the variables related to the design process and method are the epistemological beliefs and cognitive load of the learners. The purpose of the current research was to investigate the relationship between scientific epistemological and cognitive load with ideation in the design process of architecture students. The research method is a combination of quantitative (descriptive-correlation) and qualitative (analyzing samples of students' Sketches). Its statistical population included all architecture girl students in Hamadan universities. The desired sample of 120 people was selected in an accessible way. Scientific epistemology, cognitive load and idea evaluation scale questionnaires were used in the design. The research data were analyzed by descriptive statistics (mean, standard deviation, skewness and skewness statistics) and inferential statistics (Pearson's correlation and path analysis with the calculation of its defaults). The results of the research showed that there is a relationship between the beliefs of scientific epistemology and cognitive load with ideation in the design process of architecture students and it has provided a framework for recognizing and explaining the theoretical relationships between the components of scientific epistemological beliefs, cognitive load and the idea of sketches. The learning process in architectural design and cartography courses includes the stages of analytical comprehension, critical thinking, and creative processing, so scientific epistemological belief and cognitive balance or cognitive load are good explanations and predictors for ideas in students. Based on the results of the research, it is suggested to pay attention to the reduction of Intrinsic and Extraneous cognitive load in planning the education of architecture students, as well as Germane cognitive processing so that they can make better progress in the field of design. The development of scientific epistemological beliefs is also recommended for generating and analyzing ideas

Mezo-gözenekli MCM-41'in sıcak gazlardan kükürt giderme sorbentlerinde inert taşıyıcı olarak kullanılması

Gases from gasification processes mostly contain H2S, which is a very corrosive and poisonous gas, causes serious problems in applications where they are used. Thus, in many cases it is necessary to reduce the H2S concentration in these gases from percent to ppm level. For example, the allowable H2S concentration for the combine cycle power plants is 20-100 ppm while it is required to be lower than 1 ppm for the fuel cell systems. Removal of H2S form gases is a serious problem and needs to be solved for the fuel cell applications. A lot of studies have been devoted to this subject. In these studies, commonly metals and metal oxides were investigated as adsorbent material for this purpose. It was found from the studies that the suitable  metals are Ca, Co, Cu, Fe, Mn, Mo and Zn. Cu and Zn, with their superior properties, are classified as most favorable  metals. The pure metal oxides used as adsorbents, however, suffer from evaporation, loss in the surface area and porosity, sintering and mechanical disintegrations that affect their performance and life time adversely. For example, there is a loss problem due to evaporation for metallic Zn at elevated temperatures or there is a surface area loss problem for porous Cu. In order to overcome these problems, pure metal oxides or their admixture are loaded to inert carriers/supports with high surface areas. These are composite materials that consist of an active metal oxide(s) and an inert carrier. The main properties required for carrier materials are to be inert, high surface area, channels of large diameters, good mechanic strength, no phase change during sulfidation-regeneration process and hydrophobicity. Some inert oxides such as Al, Ti, Zr oxides and high silica zeolites are the most commonly used carriers. In this study, an adsorbent was prepared by using copper and mesoporous silica material for the H2S removal from hot gases. CuO was used as the active component and mesoporous MCM-41 was used as the carrier materials. CuO/MCM-41 type adsorbent was prepared by wet impregnation method, in which copper was loaded to the MCM-41 mesoporous material. The silica based carrier was also synthesized as a part of the study. By using wet impregnation method, one CuO/MCM-41 type adsorbent sample was prepared. The adsorbent sample contains 37.46% Cu by weight. The fresh and sulfided adsorbent samples were characterized by using X-ray diffraction (XRD), nitrogen adsorption, chemical analysis, thermal gravimetric analysis (TGA), H2-chemisorption. The H2S removal characteristics of the adsorbent sample from hot gases were investigated by using a laboratory scale fixed bed reactor of 14 mm diameter. The experimental set up consisted of three major sections: 1. gas supply, 2. reactor, and 3. gas analysis unit. Experiments were carried out as sulfidation-regeneration cycles at a temperature range of 823-873K. In these experiments, a gas mixture of H2S (2000 ppm), H2 (20%) and N2 (balance) was fed into the reactor in the sulfidation steps. Sulfidation steps were ended, when the H2S concentration of the reactor effluent reached 20 ppm which was selected as the breakthrough point.  Regeneration of the sulfided adsorbent samples were carried out by gas mixtures composed of (5-10%) and N2 (balance). The results of the nitrogen adsorption analysis showed that, the adsorbent sample that was prepared by wet impregnation method, has lower BET surface areas and lower pore volumes than that of the original carrier material, MCM-41. This result indicates that the loaded CuO, partly plugs pores and pore inlets of the carrier. The decrease in the BET surface area in the pelletized samples was approximately 66% for CuO/MCM-41. The drop in pore volume was measured to be 72% for the same sample. The sample was tested for three consecutive sulfidation-regeneration cycles. The average breakthrough point sulfur capacities of the CuO/MCM-41 type adsorbent sample was determined to be 1.89 g S/100 g adsorbent, after three cycles. The XRD and nitrogen adsorption analysis indicated that the structure of the sample was distructed to some extend during the sulfudation-regeneration processes. In spite of this fact, change in the sulfur up take was not comparable and remained rather limited. Keywords: Desulfurization, MCM-41, wet impregnation.Yüksek oranda kükürt içeren fosil yakıtların gazlaştırılmasıyla elde edilen hidrojence zengin gaz karışımları birçok safsızlık içerir. Bu safsızlıkların türü ve miktarı gazlaştırılan fosil yakıtın kaynağına ve türüne göre değişiklik gösterir. Gazların içerdiği H2S, özellikle yakıt hücresi gibi uygulamalarda yakıt hücresi elektrotlarını zehirleme gibi ciddi sorunlara yol açmaktadır. Bu çalışmada, bu tür sıcak gazlardan hidrojen sülfürün (H2S) uzaklaştırılması amacıyla kullanılabilecek yenilenebilir sorbentlerin geliştirilmesi hedeflenmiştir. Yapılan çalışmalar periyodik tabloda yer alan geçiş metallerinin birçoğunun bu amaçla kullanılabileceğin göstermiştir. Ancak,  bu metallerin tek başlarına kullanılmaları durumunda, kükürt tutma kapasitesinin süreç içinde önemli ölçülerde azalması, yüzey alanlarının küçülmesi, termal ve mekanik özelliklerinin yetersiz kalması gibi sorunlarla karşılaşılmaktadır. Bu sorunları çözmek için başvurulan yöntemlerden bir tanesi de bir taşıyıcının kullanılmasıdır. Bu çalışmada, mezo-gözenekli bir malzeme olan MCM-41’ın taşıyıcı olarak kullanıldığı CuO/MCM-41 tipi sorbent geliştirilmiştir. Kullanılan MCM-41 yine çalışma çerçevesinde sentezlenmiştir. Taşıyıcı malzemeye, bakır nitrat kullanılarak yaş emdirme yöntemi ile CuO yüklenmiştir. Numunenin kükürt tutma özelikleri, 2000 ppm H2S içeren, azot hidrojen karışımı kullanılarak incelenmiştir. Çalışmalar sırasında H2S için eşik nokta (breakthrough point) derişimi 20 ppmv olarak seçilmiştir. Deneysel çalışmada elde edilen sonuçlar MCM-41’in sıcak gazlardan kükürt gidermek amacıyla kullanılacak sorbentlerin hazırlanmasında taşıyıcı malzeme olarak kullanılabileceğini göstermektedir. %37.46 oranında Cu içeren sorbentin eşik nokta kükürt tutma kapasitesi 3. kükürt tutma-yenilenme döngüsü sonunda yaklaşık olarak 1.89 g S/100 g sorbent, kapasite kullanma oranı ise yaklaşık %10 olarak ölçülmüştür. Kükürt tutma-yenilenme süreci, sorbentin yapısında bazı değişmelerin meydana gelmesine neden olmakta, ancak sorbent işlevini sürdürmeye devam edebilmektedir.  Anahtar Kelimeler: Sıcak gazlar,  H2S giderme sorbenti,  MCM-41

Sequential amine functionalization inducing structural transition in aldehyde-containing zeolitic imidazolate framework: application to gas separation membranes

A modification in the gas separation performance of zeolitic imidazolate framework (ZIF)-supported hollow fiber (HF) membranes by means of an imine-condensation functionalization reaction carried out by microfluidics is reported. The accommodation of voluminous amine molecules in the SIM-1, Zn(4-methyl-5-imidazolecarboxaldehyde)2, also known as ZIF-94, sod structure during the functionalization reaction caused the ZIF atoms to be rearranged in a less dense rho structure, with a wider pore diameter and a diminished CO2 affinity. These changes had effects on the membrane performance, resulting in an enhanced CO2 permeance while maintaining a good permeance–selectivity balance. ZIF aldehyde-containing SIM-1 membranes were earlier prepared on the inner side of polymeric P84® HF using a microfluidic approach. The SIM-1 membranes displayed very interesting results in the separation of gas mixtures of great relevance to the natural gas field. High selectivities in the separation of He/CH4 (160), H2/CH4 (136) and CO2/CH4 (38) mixtures were achieved, and these are the first SIM-1 membranes with such a high separation performance to the best of our knowledge. These SIM-1 membranes were in situ stepwise functionalized with long-chain amine solutions, namely, hexyl- and nonylamine. Microfluidics allowed the easy sequential implementation of this post-reaction step in the membrane fabrication procedure. An imine-condensation reaction took place between the aldehyde groups in the 4-methyl-5-imidazolecarboxaldehyde ligand forming SIM-1 and the corresponding amines. The extent of the reaction was analyzed by FTIR, TGA and XRD, together with the changes in the textural properties and the adsorption capacities.Financial support (MAT2013-40556-R, MAT2016-77290-R) from the Spanish MINECO, the Aragón Government (DGA, T05), the European Social Fund and FEDER is gratefully acknowledged

Fabrication of Defect-Free P84® Polyimide Hollow Fiber for Gas Separation: Pathway to Formation of Optimized Structure

The elimination of the additional defect healing post-treatment step in asymmetric hollow fiber manufacturing would result in a significant reduction in membrane production cost. However, obtaining integrally skinned polymeric asymmetric hollow fiber membranes with an ultrathin and defect-free selective layer is quite challenging. In this study, P84® asymmetric hollow fiber membranes with a highly thin (~56 nm) defect-free skin were successfully fabricated by fine tuning the dope composition and spinning parameters using volatile additive (tetrahydrofuran, THF) as key parameters. An extensive experimental and theoretical study of the influence of volatile THF addition on the solubility parameter of the N-methylpyrrolidone/THF solvent mixture was performed. Although THF itself is not a solvent for P84®, in a mixture with a good solvent for the polymer, like N-Methyl-2-pyrrolidone (NMP), it can be dissolved at high THF concentrations (NMP/THF ratio > 0.52). The as-spun fibers had a reproducible ideal CO2/N2 selectivity of 40, and a CO2 permeance of 23 GPU at 35 °C. The fiber production can be scaled-up with retention of the selectivity.This research was funded by the European Research Council under the European Union’s Seventh Framework Programme (FP/2007-2013), grant agreement no. 608490, M4CO2 project

Розробка композицій на основі наночастинок для кінцевої обробки текстильних матеріалів

The study is aimed at developing a stable composition based on nanodimensional silicon dioxide, which may be used for final treatment of cotton and polyester textile materials in the processes of industrial and household washing of textile products in order to improve their properties (hydroscopicity, moisture yielding capacity, moisture absorption, humidity, water vapor permeability and soiling). As a result of the performed studies, four compositions based on nanodimensional silicon dioxide were formed.The main advantages of the developed compositions are: a significant increase in indices of the properties of textile materials with different fiber composition after treatment; all the experiments were conducted at room temperature and low module processing, which indicates energy efficiency while using the developed compositions.Stabilizing properties of surfactants and polymers were revealed, the expediency of their joint use with the purpose of increasing the sedimentation and aggregation stability of the suspensions based on silicon dioxide was substantiated.Applying the methods of mathematical planning with the use of simplex centroid plan for q=3, compiled with relation to pseudo­components, allowed assessing the changes in properties in a limited area of composition components content: polymer from 0 g/l to 10 g/l, SAS from 0 g/l to 5 g/l, nanodimensional silicon dioxide of less than 10 g/l. We managed to optimize the ratio between components of the compositions using the Harrington function of desirability for maximum enhancement of properties of hydroscopicity, moisture yielding capacity, moisture absorption, water vapor permeability, humidity and soiling of the studied textile materials.The assessment of sedimentation and aggregation resistance of the developed composition formulations was carried out and the compositions were obtained, the percentage content of nanoparticles in fractions in relation to the initial content of nanoparticles increases. In the bicomponent suspension, 17.1 % of nanoparticles remain in the solution, and with adding a mixture of stabilizers their amount increases by 11.5 % for composition No. 1, by 17,1 % for composition No. 2, by 16.5 % for composition No. 3, and by 6,24 % for composition No. 4. These results indicate the existence of features of monodispersity of compositions based on nanodimensional silicon dioxide. Characteristics of the compositions change by 1–3 % as a result of their redispersion after stilling for 30 days.Negative impact of using compositions on the environment was studied by analyzing the waste solution as for the amount of surfactants. It was found that more than half of silicon dioxide remains in the waste solution. The solution to the problem of avoiding the above mentioned negative phenomena by reusing sediment was formulated. However, no specific conclusions regarding the recommendation of one of the four studied compositions were made.The results of the research may be implemented in the production of textile materials. The composition may be used as a preparation for the final treatment of textile materials with the aim of improving their marketing prospects and consumer properties. It is possible to use the developed compositions at enterprises of household services (laundries) and for individual home washing. In these cases, the use of the composition as a conditioner for rinsing is implied.Исследование направлено на разработку стабильной композиции на основе наноразмерного диоксида силициума, которая может быть использована для конечной обработки хлопковых и полиэфирных текстильных материалов.

The effect of group logotherapy on the life expectancy of cancer patients in the north of Iran: a quasi-experimental study

Introduction: Cancer as a formidable diagnosis causes the loss of life expectancy in patients. This study was conducted to determine the effectiveness of logotherapy on the life expectancy of cancer patients in the 5th Azar Hospital of Gorgan, Iran. Material and methods: This quasi-experimental study with two groups (intervention group and control group) was conducted on 40 cancer patients referred to Gorgan’s 5 Azar hospital in Golestan province in the north of Iran from 1 March 2019 to 1 December 2019. The samples were selected by simple random sampling method. The Snyder’s Hope Scale (AHS) was used for data collection. In the logotherapy group, eight 60–90 minute-long sessions were performed in 4 groups included 5 participants. The data were analyzed by SPSS-16 statistical software using descriptive statistics (mean table and standard deviation) and inferential statistics (paired t-test and ANOVA test). Results: The result of the paired t-test showed no significant difference before and after the intervention in the control group (p = 0.67), but this test showed a significant difference in the intervention group before and after the intervention (p = 0.01). The ANOVA test also showed a significant difference between the two groups (p < 0.01). Conclusion: Considering the effectiveness of logotherapy on increasing the life expectancy of cancer people, it is recommended that relevant authorities should try to use this low-cost method to address the problems related to the meaning of life and life expectancy in cancer patients, and change the attitude of patients towards life expectancy

Metal-organic framework based mixed matrix membranes: a solution for highly efficient CO2 capture?

The field of metal-organic framework based mixed matrix membranes (M(4)s) is critically reviewed, with special emphasis on their application in CO2 capture during energy generation. After introducing the most relevant parameters affecting membrane performance, we define targets in terms of selectivity and productivity based on existing literature on process design for pre- and post-combustion CO2 capture. Subsequently, the state of the art in M(4)s is reviewed against these targets. Because final application of these membranes will only be possible if thin separation layers can be produced, the latest advances in the manufacture of M-4 hollow fibers are discussed. Finally, the recent efforts in understanding the separation performance of these complex composite materials and future research directions are outlined.European Commission FP7 608490 ERC 33574

Extractivism in the world of minecraft

This thesis is based on virtual ethnographic research, through which it explores the environment of the video game Minecraft, focusing on its environmental aspects. In particular, monster theory, but also theories of modernity, extractivism and environmental critiques of development are used to analyse the data collected through this virtual ethnography. The focus is on how male and female players relate to the virtual environment of the game, and how this relationship is influenced by the 'real' world, and in turn, how it feeds back into it. Thus, through the aforementioned theories and concepts, the thesis explores the environmental dimensions of players' and players' interactions with the Minecraft environment. Keywords Extractivism, Minecraft, virtual, ethnography, monsters, player, environment, modernityDiplomová práce je založená na virtuálním etnografickém výzkumu, pomocí kterého zkoumá prostředí videohry Minecraft, přičemž se zaměřuje na její environmentální roviny. Pro analýzu dat získaných touto virtuální etnografií je využito především teorie monster, ale také teorií modernity, extraktivismu a environmentálních kritik rozvoje. Důraz je přitom kladen na to, jakým způsobem se hráči a hráčky vztahují k virtuálnímu prostředí hry, a dále jakým způsobem je toto vztahování se ovlivněno "reálným" světem a jak jej naopak zpětně ovlivňuje. Práce tedy skrze zmíněné teorie a koncepty zkoumá environmentální rozměry interakcí hráčů a hráček s prostředím Minecraftu.
