Menavigasi Jalan Menuju Perubahan: Mengkaji Faktor Rasional, Politik, dan Kultural dalam Konteks Instansi Pemerintah
Authors: Reskino Reskino , Afrizon Afrizon
Published: February 2025

This research aims to examine the influence of rational, political and cultural factors on the adoption and implementation of performance information in the context of government organizations. This research involved 85 respondents who participated in a questionnaire survey to collect relevant data. Data analysis was carried out using the multiple regression method. The research results show that in terms of the adoption of performance information, the internal group has a significant influence, while other groups do not have a significant influence. However, when we talk about the implementation of performance information, the role of internal groups and external groups both have a significant influence. This research also reveals that rational, political and cultural factors are able to explain as much as 35% of the variation in the adoption of performance information and as much as 57% of the variation in its implementation. The findings of this research provide valuable insight into the factors that influence the adoption and implementation of performance information in government organizations, as well as the extent to which these factors can explain variation in the adoption and implementation process. The implications of these findings can help government organizations to increase their efforts to adopt and implement performance information more effectively

Exploring Deficit Beliefs Among High School Math Teachers
Authors: Buontempo Jenny , Riegle-Crumb Catherine , Morton Karisma
Published: February 2025

This brief uses national data from the High School Longitudinal Study of 2009 to investigate deficit beliefs, or beliefs that students’ academic underperformance is primarily attributable to deficiencies in their home environments, among high school math teachers. Descriptive results reveal that students in low-level math courses have teachers with more deficit beliefs. Regression results show that net of extensive control variables for both student and teacher characteristics, having a math teacher with stronger deficit beliefs is significantly and negatively associated with students’ math performance. However, this negative association is not more pronounced for youth from minoritized and low socioeconomic status backgrounds.

Published: February 2025

The transition to sustainable renewable energy necessitates robust decision-making frameworks that integrate economic, environmental, and social considerations. Multi-Criteria Decision-Making (MCDM) methods have become vital for optimizing energy planning and policy formulation. This review systematically examines MCDM applications in sustainable renewable energy from 2015 to 2025 using bibliometric analysis. Data was sourced from 4,101 UGC CARE List II research papers indexed in Scopus and Web of Science via the Dimensions.ai database, applying predefined inclusion/exclusion criteria. The study identifies key trends, methodological advancements, and research gaps, highlighting the increasing adoption of hybrid MCDM approaches. Despite progress, challenges such as subjective weight assignment and model uncertainties remain. The review underscores influential contributions, assesses methodological limitations, and explores MCDM models. Future research should focus on model transparency, standardized criteria selection, and real-world applications, offering insights for policymakers, researchers, and industry stakeholders to enhance sustainable energy decision-making.
Strategically Inclusive Parties and Diversity of Representation
Authors: Acquarone Iris E.
Published: February 2025

As political institutions diversify to include multiple marginalized groups, some scholars argue that inclusion functions as a strategic, vote-seeking tool. Yet, why would traditionally dominant elites prioritize candidates from marginalized backgrounds over other strategies to gain support? I propose that the salience of marginalization within electoral contexts drives strategically inclusive parties to select diverse candidates when electoral incentives align, such as in uncertain scenarios, during electoral struggles, and when voters clearly signal a preference for inclusion. Moving beyond observational studies of party behavior, I ask party gatekeepers in Uruguay to make choices about hypothetical candidate lists in different electoral environments. I find that marginalization salience drives elites to include women, minority, and youth candidates when parties face (1) declining performance, (2) opportunities to select multiple candidates, and (3) explicit demand for inclusion. By examining elites' decision-making behavior across varied electoral conditions, this study deepens our understanding of the dynamics that drive inclusive representation.
Mid-crustal strain localisation triggered by localised fluid influx and activation of dissolution-precipitation creep
Authors: Carpenter Manon , Piazolo Sandra , Craig Timothy , Wright Tim
Published: February 2025

To understand how the mid-crust deforms is vital in understanding the spatial and temporal distribution of strain localisation, with implications for upper-crust deformation including seismic hazard. Here, we conduct fieldwork and microstructural and chemical analyses on the amphibolite-facies, 100-m-wide Upper Badcall shear zone in northwest Scotland, which deforms initially anhydrous quartzofeldspathic gneiss and a mafic dyke. We show that with increasing strain, m-scale strain distribution and mineral chemistry become increasingly homogeneous, while hydrous phases and syn-deformational quartz veins become more abundant. With increasing strain there is an overall increase in grain size, grain boundary alignment and shape preferred orientation in amphibole, plagioclase and quartz. Only amphibole and large grained quartz exhibit crystallographic preferred orientation in strained areas. Subtle microstructures that may be overlooked elsewhere, particularly in felsic gneiss, indicate dominant activity of dissolution-precipitation creep and equivalent rheological weakening in both mafic and felsic rocks. We interpret that brittle fractures in anhydrous crust allow localised fluid-infiltration, which triggers retrogressive metamorphic reactions and introduces sufficient grain boundary fluid for deformation to favour dissolution-precipitation creep over dislocation creep. Our study suggests that deformation by dissolution-precipitation creep may be more dominant in mid- to lower-crustal localised zones of deformation than previously thought.

Familial Similarity and Heritability of Personality Traits and Life Satisfaction Are Higher Than Shown in Typical Single-Method Studies
Authors: Mõttus René , Kandler Christian , Luciano Michelle , Esko Tõnu , Vainik Uku
Published: February 2025

Personality trait similarity among ordinary relatives is surprisingly low, with parent-offspring and sibling-sibling correlations usually r ≤ .15. We explain why these correlations are biased in typical single-method studies and argue that this problem can only be addressed with multi-method designs. We also explain why ordinary relative comparisons can provide a more generalizable way of estimating (additive, narrow-sense) heritability than the better-known twin comparisons. In a sample of parent-offspring (Npairs = 522), sibling-sibling (Npairs = 388), and second-degree relative pairs (Npairs = 476), who rated their Big Five personality traits and life satisfaction and were each rated by an independent informant (Nparticipants = 2,258 + informants), we found that parent-offspring and sibling correlations were about one-third higher than typically shown (r ≈ .20). Based on the ordinary relative comparisons, the heritability of personality traits and life satisfaction was about 40%, compared with about 26% typical to self-report studies. Life satisfaction was as heritable as personality traits, sharing about 80% of its genetic variance with neuroticism, extraversion, and conscientiousness. About half of life satisfaction’s phenotypic correlations with neuroticism and extraversion and its entire correlation with conscientiousness were explained by shared genetic factors. Using data from a larger sample of relatives with only self-reports (Nparticipants = 32,004; Npairs = 24,118), we provide further evidence that growing up together does not make people more similar. The results were consistent for both aggregate traits and individual items. Only multi-method designs can accurately reveal traits’ similarity among relatives, and their genetic and environmental transmission.
Nomen est omen – Serial Reaction Time Task is not a motor but a visuomotor learning task
Authors: Pedraza Felipe , Vékony Teodóra , Nemeth Dezso
Published: February 2025

The Serial Reaction Time Task (SRTT) is a widely used task to measure human and animal learning in the field of behavioural and cognitive neuroscience. A vast number of publications refer to this task as a “motor learning task” however the SRTT is also a perceptual learning task, Here, we stress that the improper use of the term “motor learning” misleads researchers and medical doctors by pointing to the exclusive role of the motor cortex. It can result in the misinterpretation of neuroscientific and clinical studies. The domino effect can continue to generate flawed hypotheses and theories.
Meta-analytic prospective associations between self-esteem and eating disorders appear to be spurious: A reanalysis and comment on Krauss et al. (2023)
Authors: Sorjonen Kimmo , Ghaderi Ata , Melin Bo
Published: February 2025

In a recent meta-analysis, Krauss et al. (2023) found support for a reciprocal model of low self-esteem and eating disorders where, in a vicious circle, low self-esteem makes people more vulnerable to developing eating disorders and eating disorders, in turn, scars individuals’ self-esteem. However, the present reanalyses of the same meta-analytic data found the prospective decreasing effects between self-esteem and eating disorders to be spurious, probably due to correlations with residuals and regression to the mean. Consequently, the claims by Krauss et al. can be challenged. To avoid statistical artifacts, we recommend researchers to fit, as we did in the present study, competing models to their data in order to evaluate if prospective effects may be genuinely increasing or decreasing or if they appear to be spurious.
Psychophysical distance between visually presented pairs of ratios
Authors: Gomez David Maximiliano , Dartnell Pablo
Published: February 2025

Research has long investigated adults’ capacity to compare numerosities presented visually as sets of dots. It has been proposed that results are better explained by assuming a logarithmic—rather than linear—distance model between numerosities. In contrast, research about the capacity to compare numerosity ratios has received less attention. In this paper, we directly contrasted linear and logarithmic distance models in the context of a visual ratio comparison task. We present data from a task where adult participants compared two sets of red and blue dots and selected the one with a larger ratio of a given color. At the group level, the logarithmic distance model provided a better fit for participants' responses and response times compared to the linear model. At the individual level, the results favored again the logarithmic model for participants’ responses but not for response times. Overall, our findings suggest that visual ratio comparison follows psychophysical laws similar to those observed in numerosity comparison, contributing to disentangling the possible underlying cognitive mechanisms processes.
Decision-Making in Sharing Personal Information of Others: An Empirical Investigation
Authors: Parsaeian Mohamad Rasoul , Vahabie Abdol-Hossein , Ahmadabadi Majid Nili
Published: February 2025

The sharing of personal information by data collection entities has significantly impacted social processes, especially in recent years. This study aimed to examine the relationship between dark personality traits (Machiavellianism, psychopathy, and narcissism), social value orientation, and the behavior of sharing others' personal information. We also investigated the effect of incentives on behavior change, where participants were tempted with the possibility of gaining information about the individuals whose data they were sharing. Participants completed measures of dark personality traits and made decisions about sharing others' personal information in pre-test and post-test conditions with varying levels of incentives. Results indicated no significant relationship between dark triad scores and decisions to share information in the initial introduction stage or in the presence of incentives. Additionally, no significant difference in dark triad scores was found between individualistic and prosocial groups based on social value orientation. These findings contribute to our understanding of the factors influencing personal information sharing behaviors.
Gender differences in paid work over time: Developments and challenges in comparative research
Authors: Hipp Lena , Kelley Kristin
Published: February 2025

This paper examines gender differences in paid work over time and illustrates the pitfalls encountered by any comparative research that only considers either labor force participation rates or average working hours. To do so, we analyze harmonized survey data from Europe and the United States from 1992 to 2022 (N=43,283,172) and show that more progress was made in closing gender gaps in labor force participation rates than in working hours. In most countries, women’s labor force participation rates increased considerably, but their average working hours decreased, whereas both men’s labor force participation rates and average working hours decreased or stagnated (but nonetheless still remained much higher than women’s). We show and argue that these countervailing trends in working hours and labor force participation rates make it difficult to paint a coherent picture of cross-national differences in women’s and men’s paid work and of changes over time. In response, we propose “work volume” as a supplementary or alternative measure for any type of comparative research. Work volume records zero working hours for nonemployed individuals and thus allows straightforward comparisons between women’s and men’s (or any other groups’) involvement in paid work. Using the proposed work volume measure, we show that gender gaps in paid work decreased over time, but that even in 2022, men’s involvement in paid work remained considerably higher than women’s—with gender gaps being lowest in the Scandinavian and the former Communist countries.
On the “Catching Up” Model of Self-awareness of Russia as a Civilization
Authors: Averianov V. V.
Published: February 2025

The article reveals the problem of “catching up” with the model of self-awareness and delayed worldview re­flection in connection with the historioso- phical concept of pseudomorphosis proposed by Oswald Spengler. The problem is inves­tigated in the optics of a new methodology of tradition-civilization as an indissoluble sociocultural complex. The article shows that the Russian philosophical and social thought proposed two large-scale programs to overcome the pseudomorphological type of development: Pochvennichestvo in the 19th century and Eurasianism in the 20th century. The creation of such programs represented a kind of jerks provoked by an identity crisis. Pochvennichestvo has ad­vanced from its environment and defended the original theory of civilizations (cultural and historical types) of Nikolai Danilevsky. This program and N. Danilevsky's system were a reaction to Russia's defeat in the Crimean War and the collapse of the illu­sions of Eurocentrism and Russia's organic entry into the family of European states. In turn, Eurasianism was formed as a world­view response to the cascade of revolutions of the early 20th century and the continua­tion of a radical Western pseudomorphosis at a different level. The proposed two pro­grams were not only reactive, but also pro­active: they comprehended the historical traumas experienced by Russia, and at the same time forecasts and scenarios of the fu­ture were built, and an impulse was given to a comprehensive scientific study of Russia as a civilization.
Presenting the results of landslide susceptibility mapping using partial least squares regression model: A case study of Khotang District, Koshi Province
Authors: Bhattarai Sabin , Shrestha Suchita , Nir Rabin , Karki Kabita
Published: February 2025

Landslides pose a significant threat in mountainous regions globally, causing substantial damage to infrastructure, disrupting livelihoods, and leading to loss of life. This study focuses on the Khotang District, Koshi Province, Nepal, a region highly susceptible to landslides due to its steep terrain, active tectonics and heavy monsoon rainfall. The research aims to assess landslide susceptibility in the district using Partial Least Squares Regression model (PLSR), a robust statistical technique capable of handling complex datasets with correlated variables. The research emphasizes the significant influence of topographic factors on landslide occurrence. Specifically, the Topographic Wetness Index (TWI) and Elevation were found to be the most influential variables, demonstrating the highest importance scores in the PLSR model. The model demonstrated excellent performance in predicting landslide susceptibility, with a balance between fit and generalization. It achieved a testing AUC of 0.740, indicating strong generalization ability and potential for practical applications. The findings of this study indicate the potential use of the PLSR for future landslide susceptibility mapping, owing to its robust predictive power. The study also enhances our understanding of the factors that influence landslide occurrences in the Khotang District. Furthermore, it provides a scientific basis for the implementation of effective mitigation measures to reduce landslide risks.
Implications of major oxides and trace elements geochemistry in recent river sediment provenance: An overview
Authors: Karki Kabita , Shrestha Suchita
Published: February 2025

The geochemical analysis represents a potential approach for understanding sediment provenance, important aspect for source characterisation, weathering pattern and understanding the transport mechanism. This study highlights the significance of major oxides such as CaO, SiO2, Al2O3, Na2O etc. and trace elements such as Al, Fe, Ti, Th etc. as key indicators in providing insights into recent river sediment provenance. These geochemical markers help to unravel sediment source characteristics, weathering, and erosion processes despite the complexities introduced by factors such as grain size sorting, mixing, and hydrodynamic effects. Methods such as the A-CN-K diagram, elemental ratios, and inter-element relationships are particularly powerful for analysing recent sediments, as they help define source geochemistry and recent weathering and erosion patterns. Major oxides and trace element geochemistry are therefore used as a powerful tool for investigating sediment provenance in recent river sediments. This study aims to provide an overview of major and trace element proxies, including the chemical index of weathering and elemental ratios commonly used in provenance evaluation, while assessing their strengths and limitations in determining sediment origin. Their major strength lies in their ability to define source geochemistry and recent weathering and erosion patterns. However, the challenge lies in their inability to distinguish sources with similar lithology. To address this, it is suggested to use the A-CN-K diagram in combination with inter-element ratio relationships for a more comprehensive and accurate analysis.

Water is an invaluable natural resource for all living organisms, but its quality can be degraded by numerous anthropogenic and geogenic activities. Such issues are especially severe in areas near mining and mineral processing industries. The objective of this study is to evaluate the suitability of drainage water for livestock, drinking, and irrigation purposes around the Barapukuria Coal Mine, Dinajpur, Bangladesh. For this purpose, ten representative water samples were collected from different places of the mine drainage water during the dry season and were analyzed for various geochemical parameters, including pH, TDS, EC, major cations (Na+, K+, Ca2+, Mg2+) and anions (Cl–, HCO3–, SO42–). These parameters can be used to evaluate whether the water met quality standards set by the EQS, WHO and Bangladesh standards. Ca2+>Na+>Mg2+>K+ and HCO3–>SO42–> Cl– are the primary cations and anions trends, where the dominating water type is Ca–Mg–HCO3. Statistical analysis shows a good correlation between the ions suggesting homogenous water quality, whereas principal component analysis indicates three factors contribute to 84.368% of the entire variation. The water quality index (WQI) reveals that the majority of water samples are of good quality. The Gibbs plot indicates all samples fall into the rock dominance groups. The analysis of irrigation quality parameters, including % Na, SAR, KI, RSBC, MH, TH, and PI, along with Wilcox, USSL, and Doneen diagrams, indicates that the drainage water tends to be of good quality. Regular monitoring of water quality is recommended from the mine area.
Superposed remanent magnetization and magnetic fabric in Triassic carbonates of Tethys Himalaya (Jomsom area, Nepal): chronological and tectonic implications
Authors: Gautam Pitambar , Yoshida Kohki , Dhital Megh Raj , Suzuki Shigeyuki , Kawamura Toshio , Gyawali Babu Ram
Published: February 2025

Carbonates from three sections in Tamba Kurkur and Mukut Formations near Jomsom in Nepal were investigated for natural remanent magnetization (NRM) and anisotropy of magnetic susceptibility (AMS). NRM comprises up to three components: a recent field component (RF) residing on magnetite/maghemite (soft coercivity: <10-15 mT) and goethite (low unblocking temperature range (Tub): <150°C), a pyrrhotite-based characteristic remanence (ChRMpyr; intermediate Tub: 180-350°C); and another based on magnetite (ChRMmag; high Tub: 400-600°C). In situ ChRMpyr, with northerly declination and steep downward inclination (average value: 58.2°, steeper than the RF (48°) by 8-13°), is linked to thermochemical processes caused by low-temperature metamorphism at or after ca. 30 Ma. Mean CHRMpyr is steeper than the expected inclination by 24°, implying to post-acquisition tilting. Bedding-tilt corrected ChRMmag from Tamba Kurkur Formation is considered primary because of (i) steep negative inclination (-54.1°) implying acquisition at ca. 35°S latitude during the Triassic, and (ii) similarity to the known primary directions from Jomsom and adjacent areas (e.g., Manang, Shiar, Dolpo). Carbonates exhibit low mean magnetic susceptibility (km = 0.7-25.8×10-8 m3kg-1) contributed by diamagnetic and paramagnetic minerals. Magnetic fabric with low degree of anisotropy (PJ <1.12) and diverse ellipsoid shapes (-0.89 < T < 0.92) is a composite of several directional patterns. Discrimination of AMS data by specific ranges of scalar parameters (km, PJ and T) and comparison with mesoscopic structures reveals patterns linked to sedimentary-compaction, metamorphic and tectonic processes/phases.

Creep-Rupture Behavior and Recrystallization in Cold-Bent Boiler Tubing for USC Applications
Authors: Shingledecker John P.
Published: February 2025

Creep-rupture experiments were conducted on candidate Ultrasupercritical (USC) alloy tubes to evaluate the effects of cold-work and recrystallization during high-temperature service. These creep tests were performed by internally pressurizing cold-bent boiler tubes at 775°C for times up to 8000 hours. The bends were fabricated with cold-work levels beyond the current ASME Boiler and Pressure Vessel (ASME B&PV) Code Section I limits for austenitic stainless steels. Destructive metallographic evaluation of the crept tube bends was used to determine the effects of cold-work and the degree of recrystallization. The metallographic analysis combined with an evaluation of the creep and rupture data suggest that solid-solution strengthened nickel-based alloys can be fabricated for high-temperature service at USC conditions utilizing levels of cold-work higher than the current allowed levels for austenitic stainless steels.

Prediction of the Loss of Precipitation Strengthening in Modern 9-12% Cr Steels – A Numerical Approach
Authors: Holzer I. , Kozeschnik E. , Cerjak H.
Published: February 2025

The creep resistance of 9-12% Cr steels is significantly influenced by the presence and stability of different precipitate populations. Numerous secondary phases grow, coarsen and, sometimes, dissolve again during heat treatment and service. Based on the software package MatCalc, the evolution of these precipitates during the thermal treatment of the COST 522 steel CB8 is simulated from the cooling process after cast solidification to heat treatment and service up to the aspired service life time of 100.000h. On basis of the results obtained from these simulations in combination with a newly implemented model for evaluation of the maximum threshold stress by particle strengthening, the strengthening effect of each individual precipitate phase, as well as the combined effect of all phases is evaluated - a quantification of the influence of Z-Phase formation on the long-term creep behaviour is thus made possible. This opens a wide field of application for alloy development and leads to a better understanding of the evolution of microstructural components as well as the mechanical properties of these complex alloys.
High Chromium Steel Forgings for Steam Turbines at Elevated Temperatures
Authors: Blaes N. , Donth B. , Bokelmann D.
Published: February 2025

The global transition toward high-efficiency steam power plants demands increasingly advanced steel rotor forgings capable of operating at temperatures of 600°C and above. The European Cost program has been instrumental in developing creep-resistant 10%-chromium steels for these critical applications, with Steel Cost E emerging as a prominent material now widely utilized in steam turbine shafts and experiencing significant market growth. Saarschmiede has pioneered a robust, fail-safe manufacturing procedure for Cost E rotors, establishing a comprehensive database of mechanical properties and long-term performance data that enhances turbine design reliability. The company has expanded its manufacturing capabilities to include Cost F rotor forgings for high-pressure and intermediate-pressure turbines, with component weights reaching up to 44 tonnes. Investigating methods to further increase application temperatures, researchers within the Cost program discovered the potential benefits of boron additions to 10%-chromium steels. Leveraging this insight, Saarschmiede has produced full-size trial rotors to develop and refine production procedures, with these prototype components currently undergoing extensive testing to validate their performance and potential for advanced high-temperature applications.

In order to meet the 2010-2020 DOE Fossil Energy goals for Advanced Power Systems, future oxy-fuel and hydrogen-fired turbines will need to be operated at higher temperatures for extended periods of time, in environments that contain substantially higher moisture concentrations in comparison to current commercial natural gas-fired turbines. Development of modified or advanced material systems, combined with aerothermal concepts are currently being addressed in order to achieve successful operation of these land-based engines. To support the advanced turbine technology development, the National Energy Technology Laboratory (NETL) has initiated a research program effort in collaboration with the University of Pittsburgh (UPitt), and West Virginia University (WVU), working in conjunction with commercial material and coating suppliers as Howmet International and Coatings for Industry (CFI), and test facilities as Westinghouse Plasma Corporation (WPC) and Praxair, to develop advanced material and aerothermal technologies for use in future oxy-fuel and hydrogen-fired turbine applications. Our program efforts and recent results are presented.
The Role of Minor Compositional Variations in the Oxidation Behavior of Chromium-Molybdenum Steels
Authors: Singh Raman R.K. , Al-Mazrouee A.
Published: February 2025

Oxide scale growth kinetics of 1.25Cr-0.5Mo and 2.25Cr-1Mo steels have been investigated and oxide scales have been characterized. In spite of the considerable difference in chromium contents of the two steels, their oxidation kinetics have been found to be similar. The similarity in oxidation behavior has been associated with formation of a protective innermost layer of silicon rich oxide in the case of 1.25Cr-0.5Mo steel and absence of such a layer in the case of 2.25Cr-1Mo steel, suggesting predominating role of Si over Cr.
The Heat Affected Zone of Boron Alloyed Creep Resistant 9% Chromium Steels and their Susceptibility to Type IV Cracking
Authors: Mayr P. , Cerjak H.
Published: February 2025

In thermal power plants, weldments of all currently used martensitic 9% chromium steels are prone to Type IV cracking in the fine-grained region of the heat-affected zone (HAZ). Japanese researchers have introduced a new martensitic steel for ultra-supercritical (USC) steam conditions that demonstrates resistance to Type IV cracking. This study compares a modified version of this boron-nitrogen balanced advanced 9Cr-3W-3Co steel with CB2, the most promising 9% Cr steel developed through the European research initiative COST, in terms of weldability. The HAZ was analyzed using the "Heat-Affected Zone Simulation" technique with a Gleeble 1500 thermo-mechanical simulator. Basic optical microscopy was complemented by advanced electron microscopy techniques, including energy-filtered TEM (EFTEM), electron energy loss spectroscopy (EELS), electron backscatter diffraction (EBSD), and energy-dispersive X-ray analysis (EDX). Phase transformations in the HAZ were directly observed using in situ X-ray diffraction with synchrotron radiation at the Advanced Photon Source (APS) of Argonne National Laboratory, IL, USA. Although both steels exhibited similar transformation behavior, their resulting microstructures after the weld thermal cycle differed significantly. At peak temperatures above 1200°C, delta ferrite formed and remained stable down to room temperature due to rapid cooling in both steels. While CB2 exhibited conventional coarse-grained (CG), fine-grained (FG), and intercritical HAZ regions, the boron-nitrogen balanced 9Cr steel did not develop a fine-grained HAZ. Since Type IV cracking primarily occurs in the FGHAZ, this alloy shows strong potential for eliminating Type IV cracking as a major life-limiting factor in heat-resistant steel weldments.

Este estudo objetivou descrever o processo de tratamento da Terapia Analítico Comportamental (TAC) e da Psicoterapia Analítica Funcional (FAP) utilizando o instrumento Psychotherapy Process Q-Set (PQS) para criar protótipos de psicoterapia. Participaram do estudo doze psicoterapeutas especialistas em TAC e sete especialistas em FAP. Os terapeutas responderam a todos os itens do PQS considerando um processo ideal de psicoterapia. Dados sociodemográficos foram coletados para todos os profissionais. Análises de confiabilidade e de componentes principais foram realizadas para avaliar a coerência nas respostas dos terapeutas TAC e FAP. Os resultados sugerem que os especialistas de TAC e FAP entendem de maneira similar o processo de psicoterapia e que um único protótipo de psicoterapia (pTAC|FAP) pode ser suficiente para explicar variações no processo clínico de ambos os modelos. Estudos futuros podem avaliar o quanto o pTAC|FAP correlaciona com o processo de psicoterapia de terapeutas treinados em TAC ou FAP.

Franjina ekonomija – solidarnost – bratstvo
Authors: Kompes Marijana
Published: February 2025

Rad obrađuje značenje i doprinos Franjine ekonomije u kontekstu ekonomske krize našega vremena. Obrađuje se njezin povijesni temelj u franjevačkoj ekonomskoj školi od 12. stoljeća nadalje koja je zaslužna za rođenje modela koji će kasnije dobiti ime tržišna ekonomija. Terminološki se pojašnjavaju socijalna praksa, socijalni nauk Crkve, socijalna etika i katoličko socijalno učenje u odnosu prema Franjinoj ekonomiji. Analiziraju se solidarnost i bratstvo kao temeljne oznake franjevačke ekonomske škole te socijalnoga nauka Crkve u odnosu na ekonomska pitanja, osobito u odnosu na metodički individualizam izražen u temeljnoj antropološkoj pretpostavci homo oeconomicusa. Kvalitativno istraživanje daje uvid u nove elemente formulirane u sklopu Franjine ekonomije u odnosu na solidarnost i bratstvo u kontekstu ekonomske krize: bratski humanizam u odnosu prema svjetovnosti te novo bratstvo.
