Clowns, fuzzy worms and blooming flowers: becoming a ‘creative child’ through arts consumption

ABSTRACT Focusing on three ‘Instagram-ready’ art installations, this article suggests that a special kind of consumer – the ‘creative child’ – is being developed at the intersection between immersive art spaces and social media technologies. Using a multi-method approach blending ethnography in art exhibitions and netnography on Instagram, the study elaborates on how a consumer ‘becoming’ – a never-ending process of forming the self – emerges from affordances of these environments that foster the elements of childlike creativity: imaginativeness, emotiveness and playfulness. It argues that ‘becoming’ goes beyond the social media performance of the self. Through approaching adult consumers as ‘creative children’, the study illustrates how the consumer is enabled to tap into creativity in novel ways, and how following the therapeutic ethos and reconnecting to the ‘inner child’ can create a sense of an open future, full of possibilities.

Agenda Setting in Media Coverage of Natural Disaster Exogenous Events: The 9.5 Sichuan Ganzi Luding Earthquake as an Example

Disaster reporting, as a special kind of news reporting, requires the media to assume more moral and social responsibilities. At present, the development of disaster reporting faces many dilemmas, such as the substitution of traditional media by new media, the difference between mainstream media and self-media communication, and the guidance of public opinion in public discussion under disaster situations. This paper analyses the disaster coverage related to the 9.5 Sichuan Luding earthquake from a communication perspective in the hope of reflecting the current dilemma of disaster coverage development. Based on big data analysis of public opinion related to the event, it explores the effect of media agenda setting on the guidance of audiences and related discussions. Through the study of the existing disaster coverage, the defects of the current disaster coverage in our country are summarized, and the corresponding improvement measures are put forward.

Entropies of the various components of the universe* *Supported by the National Natural Science Foundation of China (11875151, 12047501, 11873001, 12047564), Lanzhou City's scientific research funding subsidy to Lanzhou University, and the Postdoctoral Science Foundation of Chongqing (cstc2021jcyj-bsh0124)

In this study, we investigate the entropies of photons, ideal gas-like dust (baryonic matter), and a special kind of dark energy in the context of cosmology. When these components expand freely with the universe, we calculate the entropy and specific entropy of each component from the perspective of statistics. Under specific assumptions and conditions, the entropies of these components can satisfy the second law of thermodynamics independently. Our calculations show that the specific entropy of matter cannot be a constant during the expansion of the universe, except for photons. When these components interact with the space-time background, particle production (annihilation) can occur. We study the influence of the interaction on the entropies of these components and obtain the conditions guaranteeing that the entropy of each component satisfies the second law of thermodynamics.

On the centered co-circular central configurations for the n-body problem

For the power-law potential n-body problem, we study a special kind of central configurations where all the masses lie on a circle and the center of mass coincides with the center of the circle. It is also called the centered co-circular central configuration. We get some symmetry results for such central configurations. We show that for positive numbers α>0 and integers n≥3 satisfying 1n∑j=1n−1cscα⁡jπn≤1+α4, the regular n-gon with equal masses is the unique centered co-circular central configuration for the n-body problem with power-law potential Uα. It quickly follows that for the Newtonian n-body problem (in the case α=1) and n≤6, the regular n-gon is the unique centered co-circular central configuration.

Down closed-quasi-injectivity of partially ordered acts

Action of a pomonoid on partially ordered sets ([Formula: see text]-posets) has beautiful aspects in practical subjects such as automata theory, projection algebra and theoretical computer science which makes it always capture the interest of mathematicians. On the other hand, the study of different kinds of weakly injectivity (which category theory inherited from homological and commutative algebra) is an interesting subject for mathematicians. One of the important kinds of weakly injectivity is quasi-injectivity. In this paper, we study quasi-injectivity in the category of [Formula: see text]-posets with respect to special kind of order embeddings, namely, down-closed embeddings (dc-quasi-injectivity).

A comparison of special intrauterine balloons and intrauterine contraceptive devices in the treatment of intrauterine adhesions

PurposeThis study aimed to compare the efficacy of a special kind of intrauterine balloon (IUB) and that of an intrauterine contraception device (IUD) for patients with intrauterine adhesions (IUAs) after transcervical resection of adhesion (TCRA).MethodsIn this retrospective cohort study, after TCRA, 31 patients received a special IUB, and 38 patients received an IUD. The Fisher exact test, logistic regression method, Kaplan–Meier method and Cox proportional hazards regression model were used for statistical analysis. A two-sided value of P < 0.05 was considered statistically significant.ResultsThe readhesion rate significantly differed between the IUB group and IUD group, at 15.39% and 54.06%, respectively (P = 0.002). For recurrent moderate IUA, patients in the IUB group had lower scores than patients in the IUD group (P = 0.035). There was a significant difference in the intrauterine pregnancy rate of IUA patients in the IUB group and IUD group after treatment, with rates of 55.56% and 14.29%, respectively (P = 0.015).ConclusionPatients in the special IUB group had better outcomes than those in the IUD group, which has a certain guiding significance for clinical work.

Stock Price Prediction Based on LSTM in Python

To reduce the risk of people buying and increase the rate of return, applying a suitable model to predict stock prices is necessary. The research applies Long Short Term Memory (LSTM), which is a kind of artificial neural network in machine learning and is also a special kind of RNN. Through studying this model, the memory of LSTM is like human memory, which is composed of short-term memory and long-term accumulation. In this paper, the current data of 2020 and 2021 is to train, and the data from 2017 to 2019 is for testing. The data comes from three companies, GOOGLE, APPLE and AMAZON in the S&amp;P500 index. Meanwhile, Mean Squared Error (MSE) is used for evaluation. Finally, in comparison with the different training times, LSTM presents good applicability, achieving negligible MSE.

The selective advantage of representing correctly

AbstractHere is a widespread but controversial idea: those animals who represent correctly are likely to be selected over those who misrepresent. While various versions of this claim have been traditionally endorsed by the vast majority of philosophers of mind, recently, it has been argued that this is just plainly wrong. My aim in this paper is to argue for an intermediate position: that the correctness of some but not all representations is indeed selectively advantageous. It is selectively advantageous to have correct representations that are directly involved in bringing about and guiding the organism's action. I start with the standard objection to the claim that it is selectively advantageous to represent correctly, the ‘better safe than sorry’ argument gand then generalize it with the help of Peter Godfrey Smith's distinction between Cartesian and Jamesian reliability and the trade‐off between them. This generalized argument rules out a positive answer to our question at least as far as the vast majority of our representational apparatus is concerned. But this argument fails to apply in the case of the correctness of a special kind of representation, one that is directly involved in bringing about, and in guiding, actions. We can still maintain that it is selectively advantageous to have a reliable mechanism for producing representations of this kind.

Scale Degree Six, Diatonicism, and Chromaticism in the Piano Music of Scott Joplin

Abstract: The hardly explored piano music of Scott Joplin (ragtime pieces, waltzes, and marches) is replete with subtle harmonic details within a square framework. These include specifically interesting usages of two idioms: (1) tonic chords with an added sixth and (2) chromatic voice leading that gives rise to plenty of rare intervals. Among these, there is special use for [inline-graphic 01], a corollary of the augmented-sixth [inline-graphic 02] before a major [inline-graphic 03], and enharmonic equivalent of ♭VI. Each of these idioms serves as a special kind of pivot chord, in Harmony Club Waltz and A Breeze from Alabama respectively. Awareness to Joplin's harmonic details may help to study his historical and cultural position more precisely.

Risk factors for difficult mask ventilation and difficult intubation among patients undergoing pharyngeal and laryngeal surgery

BackgroundThe prediction of difficult mask ventilation (DMV) and difficult intubation (DI) are key questions in anesthesia fields. DMV or DI related to pharyngeal and laryngeal diseases are a special kind of difficult airways. However, there is a lack of risk factors for prediction. MethodsThis study retrospectively collected data from patients who were admitted to the Eye & ENT Hospital of Fudan University from May 2014 to May 2018 and underwent laryngopharyngeal surgery under general anesthesia. ResultsA total of 126 patients were included. Twenty patients suffered from DMV. Preoperative laryngeal obstruction classification (OR = 7.46, 95% CI: 2.56–21.76, P < 0.001) and airway patency after sevoflurane inhalation (OR = 10.96, 95% CI: 2.70–44.43, p = 0.001) were independently associated with DMV. Seventy-six patients could be intubated at the first attempt. Preoperative laryngeal obstruction grade (OR = 0.28, 95% CI: 0.13–0.62, P = 0.002), neoplasm size (OR = 0.43, 95% CI: 0.22–0.82, P = 0.011), and airway patency after sevoflurane inhalation (OR = 0.14, 95% CI: 0.05–0.36, P < 0.001) were independently associated with first-attempt successful intubation. ConclusionAmong patients with pharyngeal and laryngeal diseases, the degree of laryngeal obstruction before the operation and the degree of airway obstruction after inhaling sevoflurane are the risk factors of DMV. The degree of laryngeal obstruction before the operation, airway obstruction after inhaling sevoflurane, and the neoplasm size are the risk factors of DI.

Monitoring and control of the program comprehension teaching in a computer class environment

Introduction. The comprehension of computer programs is claimed to be a decisive faculty and even skill of any successful exercising professional duties of program engineers, for example, prototype analysis, decision making and discussion about algorithms and structures, development of detailed documentation, test development and test analysis. Exercising of the duties demands from the engineer a special competence to judge about a program behavior basing on the consideration of its source and sometimes digital codes, screenshots, execution protocols. The skill and opportunity to make trial runs can supplement but not replace the competence. Manifesting itself on particular programs it is not a presentation of an extensive and deep familiarity with the programs, but results from the experience with a lot of programs and is obscured by another competence, the competence of the developer. This paper is aimed to precise the interpretation of the notion “program comprehension”, to research the opportunities of a purposeful and enhanced teaching the program comprehension, to develop methods and tools for the assessment of the program comprehension teaching in the higher school. The aim is relevant because of current university curricula allot considerable lecture and laboratory time for teaching programming, including program comprehension. But this time is constantly not enough in view of a growing intensity of innovations in the area of the program engineering. The problem of a control over processes of the program comprehension fostering in a computer class is a key problem of achieving the aim having been set. Materials and methods. The research is based on the university syllabi, the author’s lecture notes, protocols of experimental and sample runs of the developed programs, Internet resources, such as site of the ACM and others. The following research methods were used: terminological analysis and elaboration of a vocabulary demanded in the research and discourse within the paper; modelling and simulation, including a theoretical conceptual model representation of the program comprehension, a computer program simulation of the monitoring and control over the comprehension progress; an UMLpresentation and a trial implementation of the proposed interface for the program comprehension monitoring and control. Research results. Redefinition of conceptual cognitive models of program comprehension is proposed. The program comprehension is postulated to be a state of the cognitive knowledge base that represents an actual affordance of giving correct answers to questions about an eventual program behavior. This model highlights a special kind of teaching to be called “didactic parsing” that is targeted to generate at the audience a comprehension of programs being parsed. Dynamics of question and answers during the didactic parsing is used for assessing the education success and, finally, for a control of the teaching tempo. A user interface for learning computer systems (counters, controls and policies) are proposed to assist in monitoring and control of the didactic parsing. Sample implementation of the interface is built in JL (Joint Lesson) computer system. A graph model and a corresponding simulation program are developed that capture relevant dynamic features of control over the didactic parsing and are applied for the further investigation and demonstration of general didactic parsing effects as well as an aid for planning and control of program comprehension teaching during particular lectures. Conclusion. The research results provide creation of an environment, methods and tools enabling to positively impact the processes of program comprehension attainment. In particular, they permit to control the program comprehension level at a particular audience, adjust style of teaching to be most applicable to it, refine time plans of lectures in the area of program engineering.

Galois hulls of special Goppa codes and related codes with application to EAQECCs

Galois hulls of MDS codes can be applied to construst MDS entanglement-assisted quantum error-correcting codes (EAQECCs). Goppa codes and expurgated Goppa codes (resp., extended Goppa codes) over Fqm are GRS codes (resp., extended GRS codes) when m=1. In this paper, we investigate the Galois dual codes of a special kind of Goppa codes and related codes and provide a necessary and sufficient condition for the Galois dual codes of such codes to be Goppa codes and related codes. Then we determine the Galois hulls of the above codes. In particular, we completely characterize Galois LCD, Galois self-orthogonal, Galois dual-containing and Galois self-dual codes among such family of codes. Moreover, we apply the above results to EAQECCs.

The Therapeutic Relationship: Intrapsychic and Behavioral Changes in Both Patient and Analyst.

This article explores how the therapeutic relationship facilitates intrapsychic and behavioral changes in both the patient and the analyst. Key elements of the therapeutic relationship are reviewed, including transference, countertransference, introjective and projective identification, as well as the "real relationship." Special attention is paid to the "transformative relationship," which is a special kind of bond that develops between analyst and patient that is unique and transformative. It consists of mutual respect, emotional intimacy, trust, understanding, and affection. Empathic attunement is a key element in the evolution of a transformative relationship. This attunement optimally promotes intrapsychic and behavioral changes in both the patient and the analyst. This process is illustrated by a case presentation.

Equality, diversity and inclusion: learning from laying our cards on the table

This article presents preliminary findings from a study designed to evaluate, develop and disseminate a cards resource developed to support dialogue and learning about EDI. Experience of creating cards to explore disciplinary thinking at the Universities of Hertfordshire (UH) and East Anglia (UEA) (Jarvis and Clark, 2020) was instrumental in the design. The resource is based on the concept of using ‘serious play’, a ‘special kind of intense learning experience’ (Rieber et al., 1998, p.30, 29, original emphasis) to support reflective, inclusive and transformational learning (Peabody and Noyes, 2017). Staff and students at UH and UEA who facilitate and attend sessions at which the cards are used are contributing to the research. Before sessions, facilitators are briefed about the guidance, the cards, and possible exercises for using them. At the end of sessions, facilitators and participants are invited to take part in a reflection activity. Facilitators are asked about the context, the activity, observations of participant response to the cards, their learning, the facilitator’s learning, and plans for future EDI activities. Participants are questioned about the role of the cards in their learning and thinking, what was learnt, and how this will impact their interaction with others. Preliminary findings indicate how participants are thinking about their working contexts, in particular how they initiate conversations around their personal lives, and share stories relating to equality, diversity and inclusivity, in order to make abstract terms more vivid. This study responds to a need to develop research-informed resources to use to encourage respectful, inclusive dialogue to address EDI topics with staff and students in higher education. Drawing on the preliminary findings shared here, new terms are being added to the current card set together with a blank card to allow users to generate their own cards; and a new resource comprising EDI stories is being considered.

Metaphorical Truth and Neopragmatic Realism of Hilary Putnam

Introduction. The problems of reference, truth, and realism are extremely important for contemporary philosophical discourse. Interesting interpretations of these problems have been given by such thinkers as Paul Ricoeur and Hilary Putnam. Instead of being originally representatives of different philosophical traditions, Ricoeur and Putnam came to similar conclusions on a number of the above issues, which allows us to speak of the possible prospect of a fruitful philosophical synthesis of the two authors' positions. The aim of this paper is to justify the theoretical possibility of such a synthesis, namely to show how the different elements of Putnam's theory can be improved by using Ricoeur's approach, which is outlined in his concept of metaphorical truth. Despite the obvious proximity of the two authors, there are currently no works where Ricoeur's conception of metaphorical truth was compared with Putnam's philosophy.Methodology and sources. To meet this challenge, we have resorted to an examination of the author's primary sources, which reveal the methodology of both philosophers. Special relevance of the article is connected with the unusual perspective of considering the problems that are important for the philosophy of late 20th-early 21st century. These are problems that related to the comprehension of our thinking, the role of language in creating a picture of the world and the resulting possibility of building a special kind of ontology.Results and discussion. The study revealed many overlaps in the authors' consideration of the concept of truth, the problem of realism, and the theory of reference, as well as in the way that both philosophers define the relationship between language and reality. The most similarities were found in the relationship between Ricoeur's concept of metaphorical truth and Putnam's philosophy of inner realism.Conclusion. Thus, we can conclude that the philosophical approaches of both thinkers share a great deal of intuition about the direction in which research of truth and referential theory and the problem of realism that is one of the most fundamental problems of philosophy throughout its history can be developed.

Advancements in the computation of enclosures for multi-objective optimization problems

A central goal for multi-objective optimization problems is to compute their nondominated sets. In most cases these sets consist of infinitely many points and it is not a practical approach to compute them exactly. One solution to overcome this problem is to compute an enclosure, a special kind of coverage, of the nondominated set. For that computation one often makes use of so-called local upper bounds. In this paper we present a generalization of this concept. For the first time, this allows to apply a warm start strategy to the computation of an enclosure. We also show how this generalized concept allows to remove empty areas of an enclosure by deleting certain parts of the lower and upper bound sets which has not been possible in the past. We demonstrate how to apply our ideas to the box approximation algorithm, a general framework to compute an enclosure, as recently used in the solver called BAMOP. We show how that framework can be simplified and improved significantly, especially concerning its practical numerical use. In fact, we show for selected numerical instances that our new approach is up to eight times faster than the original one. Hence, our new framework is not only of theoretical but also of practical use, for instance for continuous convex or mixed-integer quadratic optimization problems.

Engineering Matrix Materials for Composites: Their Variety, Scope and Applications

Matrices are essentially binders for the reinforcements of composite material. Appropriate selection of fine chemicals is vital for the creation of desired matrices for generating composite materials. In fact, matrix is a subclass of a composite material. Matrices are generally of four kinds such as (i) polymer (hard as well as flexible), (ii) metal, (iii) ceramic, and (iv) cement. Each type of these subclasses of the matrix is discussed with a brief of their pros and cons. Polymer matrices are generally organic based whereas metal or ceramic matrices are inorganic in nature. Hard plastic matrix as well as flexible rubbery matrix are also discussed in the light of their applications. Carbon as matrix material for hi-tech C/C (carbon/carbon) composite materials is also stated. Cement is a special kind of inorganic matrix material because of its very special solidification mechanism during the formation of concrete composite; and it carries bulk values in the engineering area. For higher temperatures, carbon, ceramic or metal matrix materials are useful. Ceramics possess various conductivities, but they have poor tensile strength despite their ability to afford high-temperature products. Generally lightweight metals such as titanium, aluminum, magnesium, and intermetallics such as Ni-aluminide and Ti-aluminide are used; and the operating temperature can be extended to 2000 °C. The advantages of metal matrices are higher strength and ductility than those of polymers. Carbon matrix based carbon/carbon (C/C) composites can be used even at the temperature of ~3000 °C, but are preferred only in critical engineering areas of applications. Different types of matrix material may also prove to be efficacious constituent item for innovative design of integrated structure in the ever challenging area of Blast and penetration resistant materials (BPRM).

Solving Nonlinear Partial Differential Equations of Special Kinds of 3rd Order Using Balance Method and Its Models

Most nonlinear partial differential equations have many applications in the physical world. Finding solutions to nonlinear partial differential equations is not easily solvable and hence different modified techniques are applied to get solutions to such nonlinear partial differential equations. Among them, we considered the modified Korteweg–de Vries third order using the balance method and constructing its models using certain parameters. The method is successfully implemented in solving the stated equations. We obtained kind one and two soliton solutions and their graphical models are shown using mathematical software-12. The obtained results lead to shallow wave models. A few illustrative examples were presented to demonstrate the applicability of the models. Furthermore, physical and geometrical interpretations are considered for different parameters to investigate the nature of soliton solutions to their models. Finally, the proposed method is a standard, effective, and easily computable method for solving the modified Korteweg–de Vries equations and determining its perspective models.
