Abstract Background Schizophrenia has been primarily conceptualized as a disorder of high-order cognitive functions with deficits in executive brain regions. Yet due to the increasing reports of early sensory processing deficit, recent models focus more on the developmental effects of impaired sensory process on high-order functions. The present study examined whether this pathological interaction relates to an overarching system-level imbalance, specifically a disruption in macroscale hierarchy affecting integration and segregation of unimodal and transmodal networks. Methods We applied a novel combination of connectome gradient and stepwise connectivity analysis to resting-state fMRI to characterize the sensorimotor-to-transmodal cortical hierarchy organization (96 patients v. 122 controls). Results We demonstrated compression of the cortical hierarchy organization in schizophrenia, with a prominent compression from the sensorimotor region and a less prominent compression from the frontal−parietal region, resulting in a diminished separation between sensory and fronto-parietal cognitive systems. Further analyses suggested reduced differentiation related to atypical functional connectome transition from unimodal to transmodal brain areas. Specifically, we found hypo-connectivity within unimodal regions and hyper-connectivity between unimodal regions and fronto-parietal and ventral attention regions along the classical sensation-to-cognition continuum (voxel-level corrected, p < 0.05). Conclusions The compression of cortical hierarchy organization represents a novel and integrative system-level substrate underlying the pathological interaction of early sensory and cognitive function in schizophrenia. This abnormal cortical hierarchy organization suggests cascading impairments from the disruption of the somatosensory−motor system and inefficient integration of bottom-up sensory information with attentional demands and executive control processes partially account for high-level cognitive deficits characteristic of schizophrenia.

ESports, also known as competitive video gaming, has seen tremendous growth over the past few years. Several studies have been conducted that examined the potential cognitive benefits of playing video games, but few have examined the psychosocial factors needed to perform at the highest level of competitive video gaming. In this study, the researchers aimed to identify specific mental obstacles players face and any mental techniques gamers already utilize by conducting a qualitative content analysis. Interviews with five high-level competitive League of Legend players were conducted to shed light on their experiences. The interviews resulted in two high order themes. Those high order themes were the following: techniques used to achieve optimal performance and obstacles encountered by competitive gamers. The data collected can be used by a wide population in both the performance psychology field and the eSports realm, more specifically, future mental skills consultants working with League of Legends players, gamers themselves, and academics who wish to serve, improve, or study those involved in an emerging performance domain.

The National Education World is currently trying to improve the ability of its students to think critically and creatively. One of these efforts has been pursued through evaluations that also lead to critical reflection. This research is a descriptive analysis of the final semester evaluation questions that are examined from the point of view of high-level thinking [HOTS]. The reference to the HOTS criteria is that the researcher refers to the opinions of King and his friends. From the manuscript data, the issues examined are samples from the Bandung area. The results of the analysis show that 10 out of 15 HOTS ranges proposed by King are already included in the scripts made by the teachers. On the one hand, it shows the teacher's creativity in compiling questions. On the other hand, all these questions do not refer to the HOTS criteria as planned. Therefore, there is a need to increase teachers' skills in compiling scripts as HOTS. This increase can be done through teacher training.Keywords: Evaluation, HOTS, critical thinking and creativity thingking

The article presents processing module of experimental thermal characteristics of machine tools in real time using high order derivatives. It is developed in a high level programming language. This module is a part of automated system of tests and diagnostics of machines thermal state. The module is equipped with a graphical user interface; it works in real time, allows performing procedures for smoothing experimental thermal characteristics and determining their prognostic values. This allows building curves of speed, acceleration and sharpness of temperature change over the time. The developed software module implements a new algorithm based on the Horner’s method. The practice of developing algorithmic software shows that the chosen method is very convenient and effective for machine implementation, due to the absence of a division operation at each computational step. It is experimentally confirmed that the total costs of performing the calculations of high order derivatives of an arbitrary degree polynomial using the Horner’s method according to the described algorithm are acceptable for real-time calculations on a standard personal computer. Data temperature and temperature movements of the machine working bodies can be processed using the developed algorithms. In addition, this algorithm allows calculating the value of the approximating polynomial and simultaneously obtaining the values of all its derivatives at a given point. This allows to solve the problem of "shift in time by step" of the position of characteristic points.

<p class="15bIsiAbstractBInggris"><em>Entering the era of globalization, millennials, and the industrial revolution 4.0 which is full of challenges and very competitive competition, everyone must not only have global competencies (global abilities) but also must have high order thinking abilities (high-level thinking skills). In order not to be alienated and marginalized, Muslims as the majority of Indonesia's population, and the second-largest population in the world, inevitably have to have global capabilities and high-level thinking. This article, which uses library data and direct and indirect observations, proves that global abilities and higher-order thinking are part of the Islamic tradition. The sources of Islamic teachings, the Qur'an, Al-Hadith, and the history of the journey of Muslims in the golden age of the 7th to 13th centuries AD, have encouraged and given birth to a tradition of having global competence and high- thinking skills level. The background, characteristics, scope, steps, and examples of the practice of global abilities and higher thinking from an Islamic perspective can be proven in this paper. For this reason, as part of the world community that must compete and emerges as the winner, it is time for global abilities and high-level thinking to be reclaimed and put into practice.</em></p><p> </p><p><strong>Abstrak</strong></p><p class="16bIsiAbstrak">Memasuki era globalisasi, milenial dan revolusi industri 4.0 yang penuh tantangan dan persaingan yang amat kompetitif, setiap orang tidak saja harus memiliki <em>global competencies</em> (kemampuan global) melainkan juga harus memiliki kemampuan <em>high order thinking</em> (kemampuan berpikir tingkat tinggi). Agar tidak teralienasi dan termarginalisasi, Umat Islam sebagai mayoritas penduduk Indonesia, dan penduduk terbanyak nomor dua di dunia, mau tidak mau harus memiliki kemampuan global dan berpikir tingkat tinggi. Tulisan yang menggunakan data kepustakaan dan hasil pengamatan langsung dan tidak langsung ini membuktikan bahwa kemampuan global dan berpikir tingkat tinggi itu sesungguhnya merupakan bagian dari tradisi Islam. Sumber ajaran Islam Al-Qur’an, Al-Hadis serta sejarah perjalanan umat Islam di zaman keemasan (<em>golden age</em>) abad ke-7 sampai dengan 13 M, sesungguhnya telah mendorong dan melahirkan tradisi memiliki kompetensi global dan kemampuan berpikir tingkat tinggi. Latar belakang, karakteristik, ruang lingkup, langkah-langkah, dan contoh-contoh praktik kemampuan global dan berpikir tinggi dalam perspektif Islam dapat dibuktikan dalam tulisan ini. Untuk itu, sebagai bagian dari masyarakat dunia yang harus berkompetisi dan keluar sebagai <em>the winner</em>, maka kemampuan global dan berpikir tingkat tinggi itu sudah waktunya dimiliki kembali dan dipraktikkan.</p>
