Analyzing the Challenges and Obstacles to the Leadership of Professional Learning Communities in Schools and Identifying Strategies for Addressing the Obstacles: A Mixed Approach
Publisher: name: The University Of Kurdistan
Year: 2022

description: This research is with a mixed approach. The study population quantitatively\nconsisted of all Urmia’s high school principals and assistant principals (n=452).\nCochran’s formula was used to determine this quantity. 204 subjects were chosen\nas the study sample through stratified random sampling. Qualitatively, the study\npopulation who consisted of the professors of education faculty, school principals\nand experts of education departments was chosen by a purposive sampling—\nsnowball. That is to say, 13 subjects were chosen by the theoretical saturation\ntechnique. To collect the quantitative data, a researcher-made questionnaire\nensuring a face and content validity of 0.88 was developed by the experts. The\nqualitative data were collected according to semi-structured interviews. The data\nanalysis was performed by two software programs—SPSS and MAXQDA. The\nresults of the quantitative findings suggested that the challenges and obstacles to\nthe leadership of professional learning communities are not in satisfactory\ncondition in schools. Furthermore, the results of Friedman’s rank test indicated\nthat the highest rank mean relates to the organizational challenges and obstacles,\nwhile the lowest rank mean was depicted by the individual challenges and barriers.\nAccording to the results of the qualitative findings, four strategies were suggested\nto address the challenges and obstacles to the leadership of professional learning\ncommunities as follows; organizational strategies, educational and selection\nstrategies, cultural strategies, and leadership strategies.

Explaining The Approach of Authentic Leadership Competence in Primary Schools
Publisher: name: The University Of Kurdistan
Year: 2022

description: Education is the most important organization emerging from within the society and at\nthe same time its creator and builder, and its impact on the progress of the society is\nvital and tangible. In the education system of any country, the primary course has a high\nposition, sensitivity, and importance. It is considered the most important academic\ncourse. This research4 was conducted with the aim of identifying the components of\nauthentic leadership competence in primary schools. Also, in terms of practical purpose,\nin terms of data type, it is qualitative research and in terms of method, it is\nphenomenological research. The method and tool used for data collection is a semi-\nstructured interview with experts in the field under study. The participants in the\nresearch were managers, professors, and experts in the field of management and\nleadership, and sampling was done by snowball method until the theoretical saturation\nlimit was reached. To determine reliability and trustworthiness, three techniques of\nreliability, transferability and confirmability have been used from the finding. After\nanalyzing the data from a semi-structured interview with 15 managers, professors, and\nexperts in the field of management and leadership, 184 concepts (decoder), 15\nsubcategories and 5 categories (knowledge, attitude, skills, characteristics and abilities,\nauthentic leadership). was extracted and finally the results of this research were\nexamined with the results of previous researches and solutions were proposed to\nimprove the use of authentic leadership in Primary schools.
Components of the Culture of Obedience in Iranian Schools
Publisher: name: The University Of Kurdistan
Year: 2022

description: The role of culture in planning and implementing educational reforms and in impacting\nthe quality of the education system has rarely been discussed. This study aims to identify\nthe features of culture in governmental primary schools for girls in Iran aged 7‒12 years.\nUsing an ethnographic approach, qualitative data were collected and analysed. The data\nwere collected based on a triangulation strategy, through observation, in-depth interviews\nwith teachers, and content analysis of the Document for Fundamental Transformation of\nthe Education System. Thematic analysis was used to discover, analyse, and interpret the\npattern of data meanings.\nThe findings reveal that specific components represent the culture of these schools: a\nuniform education system, bureaucratic structure of schools, square-shape architecture of\nschools, national curriculum, arbitrary relationships between members of the school\ncommunity, and the professional development of teachers based on the top-down\ncommand. The shared values of school members and behaviour norms are concerned with\nthe exact execution of policies and plans issued in the form of circulars from the Ministry\nof Education, which shape the daily activities of school members; this has led to the\nemergence of a culture of obedience, wherein the members comply with the expectations,\nprescribed policies, and plans set by the Ministry of Education. Although studies\nacknowledge the importance of identifying cultural context, school culture has rarely been\ninvestigated in governmental primary schools for girls in Iran. This study highlights the\nrole of education policymakers in maintaining and solidifying the existing culture in these\nschools.

The role of self-development on job performance of school principals: A case study of secondary school principals in Isfahan
Publisher: name: The University Of Kurdistan
Year: 2022

description: The present study analyses the link between self-development and job performance of\nsecondary school principals in Isfahan. The study is applied in terms of purpose and done\nby a qualitative-quantitative combined method. In the qualitative section, we use the\nthematic analysis strategy and in the quantitative section, we test the proposed research\nmodel through structural equation modelling. The statistical population included all\nsecondary school principals in Isfahan, Iran (n = 323), of whom 175 were selected via\nstratified sampling method. The data were collected via interviews and a validated\nresearcher-made self-development questionnaire with a reliability coefficient of 0.85.\nMoreover, Paterson’s (1989) standard job performance questionnaire was applied. The\nqualitative findings show 3 main categories with 16 sub-categories for the self-\ndevelopment variable and the quantitative findings indicate that school principals’ self-\ndevelopment correlates with their job performance (correlation coefficient = 0.68). The\nstructural equations modeling of principals’ self-development and job performance with\napproved fit indices revealed that self-development affects job performance (impact\ncoefficient = 0.749). The results of stepwise regression indicated that individual and\norganizational components can predict 40% of principal’s job performance. The present\nstudy shows that self-improvement through individual and organizational components\naffect the job performance of school principals. So school principals will definitely have\nbetter job performance if they can evaluate themselves, control their behaviors, gain self-\nawareness, and stay motivated by setting goals and planning.

description: The equation of state of cold baryonic matter is studied within a relativistic mean-field model with hadron masses and coupling constants depending on a scalar field. We demonstrate that if the effective nucleon mass stops to decrease with a density increase at densities $n>n_*>n_0$, where $n_0$ is the nuclear saturation density, the equation of state stiffens for these densities and the limiting neutron star mass increases. The stabilization of the nucleon mass can be realised if in the equation of motion for the scalar mean-field there appear a term sharply varying in a narrow vicinity of the field value corresponding to the density $n_*$. We show several possible realizations of this mechanism getting sufficiently stiff equations of state. The appearance of hyperons in dense neutron star interiors is accounted for. The obtained equations of state remain sufficiently stiff if the reduction of the $ϕ$ meson mass is incorporated. Thereby, the hyperon puzzle can be resolved.

Articulating School Principals’ Leadership and Core Values: Evidence from Iran
Publisher: name: The University Of Kurdistan
Year: 2022

description: This study sought to explore the core values articulated by principals with a focus on school leadership models. Considering the importance of values in educational leadership, very little research underpins the assumption of values in coupling with school leadership models. Therefore, this study employed a sequential explanatory, mixed-method research design in the Razaviyeh region located in the city of Mashhad, Iran to provide information on that topic. Data were drawn from a combination of methods, both quantitative (questionnaires administered to 350 teachers in 63 schools) and qualitative (a semi-structured interview with twenty school principals). The quantitative results first provided evidence consistent with the previous research from centralized education systems, suggesting the managerial leadership model is the dominant model in schools. The qualitative results indicated the core values articulated by principals and were categorized into terminal and instrumental values in each school leadership model. The present study aimed to contribute to this line of research by providing evidence suggesting the presence of core values according to various leadership models. Notably, these findings should be interpreted in highly centralized education systems like Iran.

Light Curve Analysis of Neon Novae
Creators: name: Hachisu, Izumi

Publisher: name: arXiv
Year: 2015
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: We analyzed light curves of five neon novae, QU Vul, V351 Pup, V382 Vel, V693 CrA, and V1974 Cyg, and determined their white dwarf (WD) masses and distance moduli on the basis of theoretical light curves composed of free-free and photospheric emission. For QU Vul, we obtained a distance of d~2.4 kpc, reddening of E(B-V)~0.55, and WD mass of M_WD=0.82-0.96 M_sun. This suggests that an oxygen-neon WD lost a mass of more than ~0.1 M_sun since its birth. For V351 Pup, we obtained d~5.5 kpc, E(B-V)~0.45, and M_WD=0.98-1.1 M_sun. For V382 Vel, we obtained d~1.6 kpc, E(B-V)~0.15, and M_WD=1.13-1.28 M_sun. For V693 CrA, we obtained d~7.1 kpc, E(B-V)~0.05, and M_WD=1.15-1.25 M_sun. For V1974 Cyg, we obtained d~1.8 kpc, E(B-V)~0.30, and M_WD=0.95-1.1 M_sun. For comparison, we added the carbon-oxygen nova V1668 Cyg to our analysis and obtained d~5.4 kpc, E(B-V)~0.30, and M_WD=0.98-1.1 M_sun. In QU Vul, photospheric emission contributes 0.4-0.8 mag at most to the optical light curve compared with free-free emission only. In V351 Pup and V1974 Cyg, photospheric emission contributes very little (0.2-0.4 mag at most) to the optical light curve. In V382 Vel and V693 CrA, free-free emission dominates the continuum spectra, and photospheric emission does not contribute to the optical magnitudes. We also discuss the Maximum Magnitude versus Rate of Decline (MMRD) relation for these novae based on the universal decline law.

description: We use a continuous-time random walk (CTRW) to model market fluctuation data from times when traders experience excessive losses or excessive profits. We analytically derive "superstatistics" that accurately model empirical market activity data (supplied by Bogachev, Ludescher, Tsallis, and Bunde)that exhibit transition thresholds. We measure the interevent times between excessive losses and excessive profits, and use the mean interevent time as a control variable to derive a universal description of empirical data collapse. Our superstatistic value is a weighted sum of two components, (i) a powerlaw corrected by the lower incomplete gamma function, which asymptotically tends toward robustness but initially gives an exponential, and (ii) a powerlaw damped by the upper incomplete gamma function, which tends toward the power-law only during short interevent times. We find that the scaling shape exponents that drive both components subordinate themselves and a "superscaling" configuration emerges. We use superstatistics to describe the hierarchical activity when component (i) reproduces the negative feedback and component (ii) reproduces the stylized fact of volatility clustering. Our results indicate that there is a functional (but not literal) balance between excessive profits and excessive losses that can be described using the same body of superstatistics, but different calibration values and driving parameters.

description: Since the start of the COVID-19 pandemic, schools in the Netherlands were forced to close twice. While education continued online, the first evidence suggests that pupils experienced a decrease in learning growth during the school closures. Therefore, the Dutch Ministry of Education, Science and Culture provided funds to set up remedial teaching programmes to minimize this decrease in learning growth. Unique data from primary school pupils in the Netherlands on standardized test scores is combined with information about the content and participation in remedial teaching programmes. A difference-in-difference design will be used to analyse whether participation in remedial teaching programmes minimizes the decrease in learning loss. Furthermore we will analyse who gets selected into the remedial teaching programmes, who benefits the most from the programmes and which characteristics of the programmes yield the best results.
Thermal Baths as Quantum Resources: More Friends than Foes?

Subjects: subject: Quantum Physics (quant-ph)

description: In this article we argue that thermal reservoirs (baths) are potentially useful resources in processes involving atoms interacting with quantized electromagnetic fields and their applications to quantum technologies. One may try to suppress the bath effects by means of dynamical control, but such control does not always yield the desired results. We wish instead to take advantage of bath effects, that do not obliterate "quantumness" in the system-bath compound. To this end, three possible approaches have been pursued by us: (i) Control of a quantum system faster than the correlation time of the bath to which it couples: Such control allows us to reveal quasi-reversible/coherent dynamical phenomena of quantum open systems, manifest by the quantum Zeno or anti-Zeno effects (QZE or AZE, respectively). Dynamical control methods based on the QZE are aimed not only at protecting the quantumness of the system, but also diagnosing the bath spectra or transferring quantum information via noisy media. By contrast, AZE-based control is useful for fast cooling of thermalized quantum systems. (ii) Engineering the coupling of quantum systems to selected bath modes: This approach, based on field -atom coupling control in cavities, waveguides and photonic band structures, allows to drastically enhance the strength and range of atom-atom coupling through the mediation of the selected bath modes. More dramatically, it allows us to achieve bath-induced entanglement that may appear paradoxical if one takes the conventional view that coupling to baths destroys quantumness. (iii) Engineering baths with appropriate non-flat spectra: This approach is a prerequisite for the construction of the simplest and most efficient quantum heat machines (engines and refrigerators). We may thus conclude that often thermal baths are "more friends than foes" in quantum technologies.

description: Within the framework of the fermion-spin theory, the charge transport in the doped Mott insulators on a honeycomb lattice is studied by taking into account the pseudogap effect. It is shown that the conductivity spectrum in the low-doped regime is separated by the pseudogap into a low-energy non-Drude peak followed by a broad midinfrared band. However, the decrease of the pseudogap with the increase of doping leads to a shift of the position of the midinfrared band towards to the low-energy non-Drude peak, and then the low-energy Drude behavior recovers in the high-doped regime. The combined results of both the doped honeycomb-lattice and square-lattice Mott insulators indicate that the two-component conductivity induced by the pseudogap is a universal feature in the doped Mott insulators.

The Pierre Auger Observatory detects these showers with unprecedented exposure and precision and the collected data are processed via dedicated software codes. Monte Carlo simulations of extensive air showers are very computationally expensive, especially at the highest energies and calculations are performed on the GRID for this purpose. The processing of measured and simulated data is described, together with a brief list of physics results which have been achieved.

description: Growth of high-quality single-crystalline InSb layers remains challenging in material science. Such layered InSb materials are highly desired for searching for and manipulation of Majorana fermions in solid state, a fundamental research task in physics today, and for development of novel high-speed nanoelectronic and infrared optoelectronic devices. Here we report on a new route towards growth of single-crystalline, layered InSb materials. We demonstrate the successful growth of free-standing, two-dimensional InSb nanosheets on one-dimensional InAs nanowires by molecular-beam epitaxy. The grown InSb nanosheets are pure zinc-blende single crystals. The length and width of the InSb nanosheets are up to several micrometers and the thickness is down to ~10 nm. The InSb nanosheets show a clear ambipolar behavior and a high electron mobility. Our work will open up new technology routes towards the development of InSb-based devices for applications in nanoelectronics, optoelectronics and quantum electronics, and for study of fundamental physical phenomena.

Not So Radical After All: Ideological Diversity Among Radical Right Voters and Its Implications for Party Competition
Creators: name: Lancaster, Caroline
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Traditionally, parties on the radical right in Western Europe have espoused socially conservative, pro-family values, in addition to their authoritarian orientations. Radical right voters are assumed to be similar. However, in light of more liberal radical right parties I ask, "What are the ideological characteristics of radical right voters in Western Europe, and what are the implications of this for party competition?" Using latent class analysis and the European Social Survey, I find that only a minority of radical right voters conform to the traditional conceptualization. Second, I show that radical right parties lose votes as their positions on social issues become more extreme and win votes as their positions on immigration become more extreme. Finally, I find that more moderate parties exist in countries with more moderate voters.

فراتحلیلی بر پژوهش های آموزش چندفرهنگی، آموزش شهروندی، تربیت اخلاقی، تربیت سیاسی و تربیت دینی در ایران
Publisher: name: دانشگاه کردستان
Year: 2022

description: بر پایه­ نظریه نهادی، پذیرفته­شدن نظام آموزشی توسط محیط بیرونی تنها در گرو نهادینه کردن ارزش­های انسانی- اجتماعی است. پژوهش حاضر بر آن بود تا عملکرد آموزشی و تربیتی مدارس ایران در نهادینه کردن این ارزش­ها را مورد ارزیابی قرار دهد. بدین­منظور، فراتحلیلی کیفی بر تمامی پژوهش ­هایی که به بررسی وضعِ موجود نظام آموزشی در نهادینه کردن ارزش ­های چندفرهنگی، شهروندی، اخلاقی، سیاسی و دینی از سال 1387 تا 1399پرداخته بودند، انجام شد. در گام نخست، 323 پژوهش شناسایی شدند که تنها 94 پژوهش به بررسی وضع موجود پرداخته بودند. پس از کنترل کیفی و پایش این پژوهش­ ها با استفاده از تکنیک کاسپ، در نهایت، 89 پژوهش به فراتحلیل راه پیدا کردند. یافته­ ها نشان داد که نظام آموزشی در نهادینه کردن ارزش ­های انسانی- اجتماعی، ضعیف و ناکارآمد عمل کرده است. از یک­سو، در آموزش ­ها، توجهی ناکافی و نامناسب به این ارزش­ ها شده است. از دیگرسو، رویکردی که در آموزش این ارزش ­ها در پیش گرفته شده است، رویکردی غیرفعال، مکانیک و محافظه ­کارانه بوده است که به یادگیری ژرفی در دانش ­آموزان نمی ­انجامد. این مساله سبب شده که دانش ­آموزان تنها در سطح مفهوم با این ارزش­ ها آشنایی پیدا کنند و گرایشی راستین و پایدار در آن­ها برای حرکت و روآوردن به این ارزش­ ها ایجاد نشود. در نهایت، تنها اهرم ­های فشار محیط بیرونی برای گذار به گونه­گون شدن مدارس است که می­تواند بستری برای نهادینه کردن ارزش­ های انسانی- اجتماعی فراهم کند که خود نیز نیازمند هموار و هم تراز شدن ساختار اجتماعی جامعه است
After the Fall: Vettori, Machiavelli, and the Refiguring of Italia in Sixteenth-Century Political Discourse
Creators: name: Policelli, Robert A.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: This thesis tracks changes in political thought in the writings of Niccolò Machiavelli and Francesco Vettori between 1512 and the 1520s. While modern historians have traditionally emphasized the early phase of their correspondence, I examine two often overlooked sources from later years: the letters they exchanged in the 1520s and Vettori's history, the Sommario della Istoria d'Italia. By the 1520s, the Italian political terrain had experienced sweeping and devastating transformations. I seek to explore the effects of those changes on these Florentines' thinking by highlighting an idea common to both of their writings-Italia. Through contrast with Vettori's thought, I contextualize the nature of Machiavelli's political observations after he had spent a decade and a half in political exile, while also shedding light on the dynamism of Italia in early sixteenth-century political discourse and historiography. In a short epilogue I suggest some ways in which a rethinking of early modern perceptions of Italia can also contribute to modern theoretical debates about the meaning of "nation."
Mimicking Nonequilibrium Steady States with Stochastic Pumps

description: We establish a correspondence between two very general paradigms for systems that persist away from thermal equilibrium. In the first paradigm, a nonequilibrium steady state (NESS) is maintained by applying fixed thermodynamic forces that break detailed balance. In the second paradigm, known as a stochastic pump (SP), a time-periodic state is maintained by the periodic variation of a system's external parameters. In both cases, currents are generated and entropy is produced. Restricting ourselves to discrete-state systems, we establish a mapping between these scenarios. Given a NESS characterized by a particular set of stationary probabilities, currents and entropy production rates, we show how to construct a SP with exactly the same (time-averaged) values. The mapping works in the opposite direction as well. These results establish an equivalence between the two paradigms, by showing that stochastic pumps are able to mimic the behavior of nonequilibrium steady states, and vice-versa.
