AbstractHigher inductive typesare a class of type-forming rules, introduced to provide basic (and not-so-basic) homotopy-theoretic constructions in a type-theoretic style. They have proven very fruitful for the “synthetic” development of homotopy theory within type theory, as well as in formalising ordinary set-level mathematics in type theory. In this paper, we construct models of a wide range of higher inductive types in a fairly wide range of settings.We introduce the notion ofcell monad with parameters: a semantically-defined scheme for specifying homotopically well-behaved notions of structure. We then show that any suitable model category hasweakly stable typal initial algebrasfor any cell monad with parameters. When combined with the local universes construction to obtain strict stability, this specialises to give models of specific higher inductive types, including spheres, the torus, pushout types, truncations, the James construction and general localisations.Our results apply in any sufficiently nice Quillen model category, including any right proper, simplicially locally cartesian closed, simplicial Cisinski model category (such as simplicial sets) and any locally presentable locally cartesian closed category (such as sets) with its trivial model structure. In particular, any locally presentable locally cartesian closed (∞, 1)-category is presented by some model category to which our results apply.

We present an algorithm for deciding polarised higher-order subtyping without bounded quantification. Constructors are identified not only modulo β, but also η. We give a direct proof of completeness, without constructing a model or establishing a strong normalisation theorem. Inductive and coinductive types are enriched with a notion of size and the subtyping calculus is extended to account for the inclusions arising between the sized types.

We give a realizability interpretation of an intuitionistic version of Church's Simple Theory of Types (CST) which can be viewed as a formalization of intuitionistic higher-order logic. Although definable in CST we include operators for monotone induction and coinduction and provide simple realizers for them. Realizers are formally represented in an untyped lambda–calculus with pairing and case-construct. The purpose of this interpretation is to provide a foundation for the extraction of verified programs from formal proofs as an alternative to type-theoretic systems. The advantages of our approach are that (a) induction and coinduction are not restricted to the strictly positive case, (b) abstract mathematical structures and results may be imported, (c) the formalization is technically simpler than in other systems, for example, regarding the definition of realizability, which is a simple syntactical substitution, and the treatment of nested and simultaneous (co)inductive definitions.

AbstractWe have built the first family of tagless interpretations for a higher-order typed object language in a typed metalanguage (Haskell or ML) that require no dependent types, generalized algebraic data types, or postprocessing to eliminate tags. The statically type-preserving interpretations include an evaluator, a compiler (or staged evaluator), a partial evaluator, and call-by-name and call-by-value continuation-passing style (CPS) transformers. Our principal technique is to encode de Bruijn or higher-order abstract syntax using combinator functions rather than data constructors. In other words, we represent object terms not in an initial algebra but using the coalgebraic structure of the λ-calculus. Our representation also simulates inductive maps from types to types, which are required for typed partial evaluation and CPS transformations. Our encoding of an object term abstracts uniformly over the family of ways to interpret it, yet statically assures that the interpreters never get stuck. This family of interpreters thus demonstrates again that it is useful to abstract over higher-kinded types.

The activities in many real-world applications, such as e-commerce and online education, are usually modeled as a dynamic bipartite graph that evolves over time. It is a critical task to detect anomalies inductively in a dynamic bipartite graph. Previous approaches either focus on detecting pre-defined types of anomalies or cannot handle nodes that are unseen during the training stage. To address this challenge, we propose an effective method to learn anonymous edge representation (AER) that captures the characteristics of an edge without using identity information. We further propose a model named AER-AD to utilize AER to detect anomalies in dynamic bipartite graphs in an inductive setting. Extensive experiments on both real-life and synthetic datasets are conducted to illustrate that AER-AD outperforms state-of-the-art baselines. In terms of AUC and F1, AER-AD is able to achieve 8.38% and 14.98% higher results than the best inductive representation baselines, and 6.99% and 19.59% than the best anomaly detection baselines.

AbstractWe present the complete development, in Gallina, of the residual theory of β-reduction in pure λ-calculus. The main result is the Prism Theorem, and its corollary Lévy's Cube Lemma, a strong form of the parallel-moves lemma, itself a key step towards the confluence theorem and its usual corollaries (Church-Rosser, uniqueness of normal forms). Gallina is the specification language of the Coq Proof Assistant (Dowek et al., 1991; Huet 1992b). It is a specific concrete syntax for its abstract framework, the Calculus of Inductive Constructions (Paulin-Mohring, 1993). It may be thought of as a smooth mixture of higher-order predicate calculus with recursive definitions, inductively defined data types and inductive predicate definitions reminiscent of logic programming. The development presented here was fully checked in the current distribution version Coq V5.8. We just state the lemmas in the order in which they are proved, omitting the proof justifications. The full transcript is available as a standard library in the distribution of Coq.

The present research studies the factors that have impacted the affective engagement of university students in an educational online course. It examines how the type of interaction (learner-learner, learner-instructor, and learner-content) and the type of engagement (behavioural, cognitive and affective) have influenced the affective engagement of the students in the online course. Nineteen university students majoring in teaching mathematics, who were enrolled in the course Mathematics Teaching Methods, participated in the present research. Two data collection tools were used: semi-structured interviews and reflections. To analyse the texts resulting from the interviews and reflections, inductive and deductive qualitative content analysis was used. The research results indicated that university students have experienced more positive than negative affective engagement in the three communicational channels used in this course to facilitate online learning, which were: synchronous lectures, forums and assignments. The results also indicated that these three types of interaction have positively influenced students’ affective engagement in the three channels, with that influence being different from one channel to the other based on the interaction type taking place. We suggest that specific types of engagement need to be attended to for positive affect to occur. Doi: 10.28991/esj-2021-01296 Full Text: PDF

This study examines the effects of inductively versus deductively organized product descriptions on Chinese and Western readers. It uses a 2 × 3 experimental design with text structure (inductive versus deductive) and cultural background (Chinese living in China, Chinese living in the Netherlands, and Westerners) as independent variables and recall, reading time, and readers’ opinions as dependent variables. Participants read a product description that explained two refrigerator types and then recommended which one to purchase. The results showed that Chinese readers rated readability and persuasiveness higher when the text was structured inductively whereas Western readers rated these aspects equally high for the inductively and deductively structured text. The results suggest that culturally preferred organizing principles do not affect readers’ ability to read and understand texts but that these principles might affect their opinions about the texts.

This study presents the experimental evaluation of a piezo-inductive mechanical system for applications of energy harvesting with low-frequency vibrations. The piezo-inductive vibration energy harvester (PI-VEH) device is composed of a voice coil motor (VCM) extracted from a hard disk drive. The proposed design allows the integration of different element types as beams and masses. The dynamic excitations in the system produce a pendular motion carried out by a hybrid arm (rigid-flexible) that generates energy with the rotations (with a coil) and the beam strains (with a piezoelectric material). The electrical assessment was performed through different working modes classified as inductive, inductive with magnetic instabilities, and piezo-inductive. The instabilities in the harvester refer to external forces induced by two magnets that repel each other. The first two inductive configurations were designed as a function of three parameters (length, mass, instability angle) to debug these using the maximum output voltage. The selected experiments were conducted in a piezo-inductive configuration. The results showed two effects on the output voltage—the first one is related to a system without resonances (higher broadband), and the second effect is associated with a multi-resonant system. As a final conclusion, it is pointed out that the electrical performance can be improved with the magnetic instabilities since these considerably amplified the output voltages.

The delay datatype was introduced by Capretta (Logical Methods in Computer Science, 1(2), article 1, 2005) as a means to deal with partial functions (as in computability theory) in Martin-Löf type theory. The delay datatype is a monad. It is often desirable to consider two delayed computations equal, if they terminate with equal values, whenever one of them terminates. The equivalence relation underlying this identification is called weak bisimilarity. In type theory, one commonly replaces quotients with setoids. In this approach, the delay datatype quotiented by weak bisimilarity is still a monad–a constructive alternative to the maybe monad. In this paper, we consider the alternative approach of Hofmann (Extensional Constructs in Intensional Type Theory, Springer, London, 1997) of extending type theory with inductive-like quotient types. In this setting, it is difficult to define the intended monad multiplication for the quotiented datatype. We give a solution where we postulate some principles, crucially proposition extensionality and the (semi-classical) axiom of countable choice. With the aid of these principles, we also prove that the quotiented delay datatype delivers free ω-complete pointed partial orders (ωcppos).Altenkirch et al. (Lecture Notes in Computer Science, vol. 10203, Springer, Heidelberg, 534–549, 2017) demonstrated that, in homotopy type theory, a certain higher inductive–inductive type is the free ωcppo on a type X essentially by definition; this allowed them to obtain a monad of free ωcppos without recourse to a choice principle. We notice that, by a similar construction, a simpler ordinary higher inductive type gives the free countably complete join semilattice on the unit type 1. This type suffices for constructing a monad, which is isomorphic to the one of Altenkirch et al. We have fully formalized our results in the Agda dependently typed programming language.

The purpose of this research was to explore how HEIs are using Social Media (SM) as a marketing communication tool and to understand their branding focus through SM. It was investigated by understanding the utilization of functional blocks of SM by HEIs, which are believed to contribute towards elements of brand equity. Utilization of functional blocks of SM was studied through theoretical lens of honeycomb framework of SM. This study used qualitative methodology, based on inductive research approach. The data was collected via Netnography method, based on six months usage of SM accounts of seven selected HEIs of Pakistan, out of 225, which exhibited active SM presence. HEIs were found using nine different content types on SM. The content types that showed highest utilization of functional blocks, i.e. endorsements and promotional-messages, were amongst the least preferred content types of HEIs. However, their most preferred content types, i.e. event coverage & announcements, showed lowest engagement level, and were seen contributing towards lower stages of brand building i.e. brand image and awareness only, thus reflecting a myopic focus of HEIs in terms of their brand building through SM. Findings of this study will enable HEIs to revisit their content preference on SM based on the desired branding objectives. This research has extended theoretical knowledge regarding SM Marketing in context of HEIs. Further, it has extended comprehension of various functional blocks of SM, in organizational context, based on literature review. Keywords: Social Media Marketing, Brand Equity, Honeycomb Framework, Higher Education Institutes.

We show how to incorporate rewriting into the Calculus of Constructions and we prove that the resulting system is strongly normalizing with respect to beta and rewrite reductions. An important novelty of this paper is the possibility to define rewriting rules over dependently typed function symbols. We prove strong normalization for any term rewriting system, such that all function symbols satisfy the, so called, star dependency condition, and every rule is accepted by the Higher Order Recursive Path Ordering (which is an extension of the method created by Jouannaud and Rubio for the setting of the simply typed lambda calculus). The proof of strong normalization is done by using a typed version of reducibility candidates due to Coquand and Gallier. Our criterion is general enough to accept definitions by rewriting of many well-known higher order functions, for example dependent recursors for inductive types or proof carrying functions. This makes it a very good candidate for inclusion in a proof assistant based on the Curry-Howard isomorphism.

PurposeMany higher education institutions are committed to developing students as skilled professionals and responsible citizens for a more sustainable future. In addition to the formal curriculum for sustainability education, there is an increasing interest in informal learning within universities. This paper aims to extend the current understanding of the diversity and significance of informal learning experiences in supporting students’ learning for sustainability.Design/methodology/approachSix focus groups were formed with 30 undergraduate and postgraduate students from an Australian higher education institution committed to supporting graduate competencies for sustainability. An inductive and qualitative inquiry was designed to enable participants to reflect on the ways in which their university experiences support meaningful and significant learning for sustainability.FindingsThe paper presents a typology of the diverse communities of informal learning that students create and engage with. These range from ongoing to transient groups, from environmentally to more socially oriented groups and from incidental to intended learning, from local to national in scale, with varying types and degrees of connection to the formal curriculum and the university campus. The paper demonstrates that these student-led experiences support three domains of learning: cognitive, practical and affective.Originality/valueDeepening the understanding of the forms and significance of student-led learning within their university experience contributes to the identification of the roles that informal learning may play alongside formal education in developing graduates as agents of change for a more sustainable future.

The article describes the possible ways of applying the achievements of corpus linguistics in the ESL classroom at the HEIs. The notion of a language corpus was defined, a journey into the history of the first corpus creation was taken, and the most popular modern English-language corpora (British National Corpus, The Oxford English Corpus, COCA, etc.) were considered. The efficiency of applying the corpus method in teaching a foreign language in higher education has been proven. Thus, the use of corpora in students' work along with the inductive method contributes to their understanding of the basic linguistic patterns and the development of linguistic intuition, the material of the study being exclusively authentic texts. The possibility of using direct and indirect corpus approach to assist the formation of students' lexical, grammatical, stylistic and phonetic skills has also been studied. The direct applying this method may include teaching corpus linguistics to university students as a purely academic subject, performing certain tasks or exercises using concordance programs and performing individual research projects by students. And the indirect corpus approach can include publishing links, developing materials and language testing. The article provides information on special software that enables one to carry out corpus training and analyzes the main types of tasks that can be created using these programs. Finally, the article discusses the reasons for the unpopularity of the corpus method in the Ukrainian HEIs at the present stage of education and justifies the appropriateness of its wider use in the future academic environment.

We present two type systems for term graph rewriting: conventional typing and (polymorphic) uniqueness typing. The latter is introduced as a natural extension of simple algebraic and higher-order uniqueness typing. The systems are given in natural deduction style using an inductive syntax of graph denotations with familiar constructs such as let and case.The conventional system resembles traditional Curry-style typing systems in functional programming languages. Uniqueness typing extends this with reference count information. In both type systems, typing is preserved during evaluation, and types can be determined effectively. Moreover, with respect to a graph rewriting semantics, both type systems turn out to be sound.

AbstractWe give a model of set theory based on multisets in homotopy type theory. The equality of the model is the identity type. The underlying type of iterative sets can be formulated in Martin-Löf type theory, without Higher Inductive Types (HITs), and is a sub-type of the underlying type of Aczel’s 1978 model of set theory in type theory. The Voevodsky Univalence Axiom and mere set quotients (a mild kind of HITs) are used to prove the axioms of constructive set theory for the model. We give an equivalence to the model provided in Chapter 10 of “Homotopy Type Theory” by the Univalent Foundations Program.

Scholars are divided over whether listing the shares of stock exchanges improves their financial performance. Applying simple OLS regressions, I test the hypothesis that exchanges’ post-IPO owners are value maximizers. However, recently demutualized exchanges have a high proportion of shareholders with conflicts of interest. Therefore, I also test whether different types of shareholders have different effects on performance. I find that investment managers behave like true value maximizers. The results also show that a higher fragmentation of share ownership is associated with lower performance. The proportion of brokers, who are the most conflicted shareholders in exchanges (since they are large customers as well as owners), is too small to have a measurable effect on performance. Most interestingly I find, by way of an inductive approach to shareholding structure, that strategic shareholders, a wide array of investors with various agendas, are on balance detrimental to shareholder value. This chapter is the first in a trilogy of articles that make up my Ph.D. dissertation. It is followed by an in-depth study of the shareholding structure of individual stock exchanges, notably in order to understand more clearly who these strategic investors are and what effects they have on exchanges.

The auxin and phenolic contents, as well as phenylalanine ammonia-lyase (PAL) activity, were determined in in vitro cultured shoots of the recalcitrant-to-root rac mutant of tobacco, and compared with wild-type shoots. The mutant and wild-type shoots showed similar auxin changes during the culture cycle, but with higher contents for the mutant. A transient peak of auxin (corresponding to the achievement of the rooting inductive phase) occurred at day 14 in both types of shoots, but earlier in the basal parts of the wild-type stems. The rac shoots contained more phenolics, corresponding with an increased PAL activity. The most abundant phenolic compound found in the two types of tobacco was chlorogenic acid, which was more abundant in the rac shoots. Rutin was also detected at a higher concentration in the mutant shoots. Basal parts of wild-type shoots treated with 10–3 M chlorogenic acid reacted by accumulating auxins and, unlike untreated controls, did not form adventitious roots. The relationships between these biochemical analyses in relation to the growth limitation of the rac mutant, and the inhibition of its root development, are discussed.

Competitive intelligence is the collection and analysis of information to support strategic decision making for an organisation, as a means to achieve competitive advantages. Identification of information needs is a prerequisite for the subsequent actions and activities in the competitive intelligence process, and, if not done well, optimal intelligence will not be provided. Intending to identify the information needs of university managers in higher education sector, this study addressed the different dimensions of information needs, information sources, and channels used by them. Due to the nature of the subject and research objectives, the research approach was qualitative based on Grounded Theory, an inductive, theory discovery methodology. Twenty-three university managers in Iran were purposively sampled for interviews. It was found that their information needs were mostly about university competitors, university customers and their higher education providers. Their information needs for strategic decisions and actions were about their collaborators in education and information field, effective marketing about product and services, as well as economic, socio-cultural and legal aspects. They need to pay attention to political and economic information in dealing with unexpected topics. Managers obtained information they needed from four types of information sources and channels - human, organisations, open source documents and captured media, and mixed channels. Electronic information sources were considered to be more abundant for them than printed sources. The paper suggests that the findings can contribute to the design, implementation, and development of competitive intelligence information systems that managers and decision-makers are among its major users.

Wireless power transfer allows the transfer of energy from a transmitter to a receiver without electrical connections. Compared to galvanic charging, it displays several advantages, including improved user experience, higher durability and better mobility. As a result, both consumer and industrial markets for wireless charging are growing rapidly. The main market share of wireless power is based on the principle of inductive power transfer, a technology based on coupled coils that transfer energy via varying magnetic fields. However, inductive charging has some disadvantages, such as high cost, heat dissipation, and bulky inductors. A promising alternative is capacitive wireless power transfer that utilizes a varying electric field as medium to transfer energy. Its wireless link consists of conductive plates. The purpose of this paper is to review the state of the art, link the theoretical concepts to practical cases and to indicate where further research is required to take next steps towards a marketable product. First, we describe the capacitive link via a coupling model. Next, we highlight the recent progress in plate topologies. Additionally, the most common compensation networks, necessary for achieving efficient power transfer, are reviewed.

Nowadays, we mainly depend on financial consultants or advisors to conduct risk assessments for individual investors before providing them with any investment advice or recommendations. Individual investors should understand the risk level of their investment choices and their investment decisions should match their risk profile. This process is usually conducted in face-to-face meetings. However, during the recent coronavirus disease 2019 pandemic, which has seriously impacted daily life with social distancing, in order to maintain sustainability, contact-free advising, such as robo-advising, becomes more important. The aim of this paper was to assess customers’ risk in regards to investment and identify important risk factors needed to profile individual risk preferences, in order to prepare for robo-advising. Inductive content analysis is applied to classify 180 questions from 20 risk assessment questionnaires, sourced from banks and investment service providers, into different types. Then, the number of types is reduced by collapsing similar areas into broader higher order categories (the important risk factors). This paper also makes specific recommendations for the implementation of risk profiling in robo-advising.

Biochemical markers have been used for the analysis of plant cells submitted to several types of stress, among them salinity. This work aimed at analyzing the effect of saline stress in callus of Eucalyptus urograndis on polyamine contents. Explants (hypocotyls) obtained from seeds were inoculated in callus inductive medium, submitted to different levels of NaCl and analyzed at 10, 20 and 30 days after the inoculation. The free polyamines were extracted, isolated and quantified using TLC (Thin-Layer Chromatography). Putrescine content was higher and a fall in the spermidine content was observed in callus submitted to salinity condition. The results showed that polyamine accumulation is related to NaCl exposure in callus of Eucalyptus urograndis. The decrease in spermine content could be used as a biochemical marker for Eucalyptus callus subjected to salinity.

We discuss qualitative inductive studies in organizational and management research, particularly case studies, action research inquiries and research based on the grounded theory method. We posit that such qualitative inquiries are insufficiently capitalized upon and that, if aggregated through meta-studies, could yield insight on emergent properties and permit the development of higher-order knowledge, and theory. We contribute in four ways: Firstly, we introduce the construct of emergence and evidence its properties to generate meta-knowledge. Secondly, we propose a pragmatic approach to conducting meta-analyses of qualitative studies and contextualize it in terms of a concrete application. Thirdly, we identify major methodological issues that occur in the review of qualitative studies in management and organizational research-especially when aggregating different types of evidence and in terms of methodological robustness. Fourthly, we conclude by proposing some pragmatic remedying ideas.

Compensation is crucial in the inductive power transfer system to achieve load-independent constant voltage or constant current output, near-zero reactive power, higher design freedom, and zero-voltage switching of the driver circuit. This article proposes a simple, comprehensive, and innovative graphic design methodology for compensation topology to realize load-independent output at zero-phase-angle frequencies. Four types of graphical models of the loosely coupled transformer that utilize the ideal transformer and gyrator are presented. The combination of four types of models with the source-side/load-side conversion model can realize the load-independent output from the source to load. Instead of previous design methods of solving the equations derived from the circuits, the load-independent frequency, zero-phase angle (ZPA) conditions, and source-to-load voltage/current gain of the compensation topology can be intuitively obtained using the circuit model given in this paper. In addition, not limited to only research of the existing compensation topology, based on the design methodology in this paper, 12 novel compensation topologies that are free from the constraints of transformer parameters and independent of load variations are stated and verified by simulations. In addition, a novel prototype of primary-series inductor–capacitance–capacitance (S/LCC) topology is constructed to demonstrate the proposed design approach. The simulation and experimental results are consistent with the theory, indicating the correctness of the design method.

Studies on phraseological competence have attracted researchers from different fields, particularly TESOL. However, rarely have scholars in the field studied IELTS candidates. This study intended to explore the different types of phraseological units in IELTS academic writing task 2 and probe into the IELTS candidates’ perceptions of Phraseological competence. To this end, a corpus entailing 100 essays (26,423 words) written for IELTS writing task 2 was scrutinized, through which phraseological units were extracted, and their types were identified based on Moon’s (2019) typology. In addition, semi-structured interviews were conducted with nine IELTS candidates. The results indicated that simple formulae were the most commonly used phraseological units in IELTS writing task 2. Using inductive thematic and summative content analyses, the interview data also demonstrated that IELTS candidates had varying perceptions of phraseological competence, wherein higher band score candidates appeared to have a deeper and more accurate understanding of the concept. As for the candidates’ perceived phraseological competence, they were found to under-or overestimate their own competence at using phraseology. The findings of the study can be employed in making learner dictionaries based on the phraseologies used in IELTS.

Asking questions is key to advancing knowledge and asking the creative questions is especially important. Being able to properly frame and focus on the creative questions is an important skill but this isn’t something that is taught or evaluated within educational systems. Professor Fumihito Ikeda, Brain Science Research and Education Center, Institution for the Advancement of Higher Education, Hokkaido University, Japan, believes that nurturing children’s development of creative questioning skills at school would be beneficial for the leaders of tomorrow. He and his team are developing test questions and training programmes for schools that generate questions focused on three types of logical reasoning: inductive, deductive and abductive. Ikeda’s goal is to develop and train mainly primary and high school students in question-intelligence. A test question using the three types of reasoning was created and tried on around 200 high school students. The researchers utilised, a deep neural network (DNN), a form of machine learning, to assist in the automatic classification and evaluation of questions.Ikeda plans to create an inquiry learning programme that will improve the quality of scientific questions while asking different types of logic in order to collect more appropriate questions for DNN to learn. He will use his partnerships with the Japan Society for Science Education and the Japan Creativity Society to roll these programmes out to students at educational institutions.

There is a huge interest in developing novel hollow fiber (HF) membranes able to modulate neural differentiation to produce in vitro blood–brain barrier (BBB) models for biomedical and pharmaceutical research, due to the low cell-inductive properties of the polymer HFs used in current BBB models. In this work, poly(ε-caprolactone) (PCL) and composite PCL/graphene (PCL/G) HF membranes were prepared by phase inversion and were characterized in terms of mechanical, electrical, morphological, chemical, and mass transport properties. The presence of graphene in PCL/G membranes enlarged the pore size and the water flux and presented significantly higher electrical conductivity than PCL HFs. A biocompatibility assay showed that PCL/G HFs significantly increased C6 cells adhesion and differentiation towards astrocytes, which may be attributed to their higher electrical conductivity in comparison to PCL HFs. On the other hand, PCL/G membranes produced a cytotoxic effect on the endothelial cell line HUVEC presumably related with a higher production of intracellular reactive oxygen species induced by the nanomaterial in this particular cell line. These results prove the potential of PCL HF membranes to grow endothelial cells and PCL/G HF membranes to differentiate astrocytes, the two characteristic cell types that could develop in vitro BBB models in future 3D co-culture systems.

Despite evidence that stress relates negatively to cognitive functioning in older adults, little is known how appraisal of stress and socioeconomic meso-level factors influence different types of cognitive functions in older adults. Here, we assess the relationship between perceived stress (PSS scale) and a battery of cognitive functions, including prospective memory in 1054 older adults (65+). A moderator analysis assessed whether this relationship varies with neighborhood socioeconomic status using an area-based measure of Socioeconomic Position (SEP). Perceived stress was associated with worse processing speed, verbal fluency, and inductive reasoning. The perceived self-efficacy subscale of the PSS is related to better performance in these measures. Higher self-efficacy was also associated with better prospective memory; this relationship was more pronounced for people with high neighborhood SEP. These findings indicate that not only do perceived stress and perceived self-efficacy relate to cognitive functioning in older age but also that neighborhood SEP is a moderator of this relationship.

Despite post-apartheid South Africa’s human rights-based education policies, a range of practices, including curriculum design and teaching strategies, continue to disproportionately disadvantage students with disabilities (SWDs). The disadvantage of SWDs that are caused by these practices, results in low access, throughput, and success rates for this group. Recently the situation has been exacerbated by many South African universities' recourse to emergency remote online learning as a result of the effects of COVID-19 pandemic lockdowns. The remote learning strategy disadvantaged SWDs, particularly those with invisible disabilities such as mental health challenges, whose voices, as evidenced by this study, continue to be overlooked. The purpose of this study was to explore how SWDs are experiencing emergency remote online learning during the COVID-19 lockdown. Online self-administered questionnaires were used to collect data from five postgraduate students with mental health challenges at one historically white university in South Africa. Data were coded and analysed using Braun and Clarke’s (2006) method of inductive and deductive thematic analysis, and Nancy Fraser’s approach to social justice was used as a theoretical lens. The study identified numerous barriers that highlight the under-preparedness of the sampled university in providing equal educational opportunities, with students with mental health challenges as well as those with other types of invisible disabilities being disproportionately affected. This study has added new knowledge by identifying both new challenges and opportunities for emergency remote online learning for students with mental health challenges. Thus, the study calls for universities to achieve parity of participation for students with mental health challenges by consulting with these students if higher education institutions (HEIs) are to effectively support this group to overcome the identified emergency remote online learning-oriented barriers.

We extend the proof-irrelevant model defined in Smith (1988) to the whole of Martin-Löf's logical framework. The main difference here is the existence of a type whose objects themselves represent types rather than proof-objects. This means that the model must now be able to distinguish between objects with different degree of relevance: those that denote proofs are irrelevant whereas those that denote types are not. In fact a whole hierarchy of relevance exists.Another difference is the higher level of detail in the formulation of the formal theory, such as the explicit manipulation of contexts and substitutions. This demands an equally detailed definition of the model, including interpreting contexts and substitutions.We are thus led to a whole reformulation of the proof-irrelevant model. We present a model that is built up from an arbitrary model of the untyped lambda calculus. We also show how to extend it when the logical framework itself is enlarged with inductive definitions. In doing so, a variant of Church numerals is introduced.As in Smith (1988), the model can only be defined in the absence of universes, and it is useful to obtain an elementary proof of consistency and to prove the independence of Peano's fourth axiom.

Background: Vocational interventions aimed at increasing job retention for people with multiple sclerosis (MS) are reliant upon a partnership with a supportive work environment. A better understanding of the types of psychosocial support that are most conducive to retaining employees’ sense of work-efficacy will enhance the success of interventions aimed at reducing workplace barriers to job maintenance. Objective: The objective of this study is to identify the types of psychosocial support that people with MS require post-disclosure, in order to maintain their employment status. In particular, we examined the roles of psychological safety and work-efficacy. Methods: We interviewed 40 employees with MS either individually ( n = 25) or within three focus groups ( n = 15). These interviews were audio-taped and the content analysed, using an inductive thematic approach. Results: Themes to emerge in organisational responses to disclosure were: a focus on ability (leading to enhanced perceptions of psychological safety and higher work-efficacy) and on disability (leading to diminished psychological safety and reduced perceptions of work-efficacy). Conclusion: Organisational responses to disclosure demonstrating trust and inclusive decision making, and focussing on employee abilities, enhance perceptions of psychological safety at work. This increases the likelihood that employees with MS will retain their sense of work-efficacy and reduce their intentions to leave.

Abstract The 11β-hydroxysteroid dehydrogenase (11β-HSD) system plays a pivotal role in glucocorticoid (GC) and mineralocorticoid (MC) action. Although 11β-HSD activities are important determinants for the efficacy of synthetic MCs and GCs, corresponding pharmacokinetic data are scanty. Therefore, we characterized 11β-HSD profiles for a wide range of steroids often used in clinical practice. 11β-HSD1 and 11β-HSD2 were selectively examined in 1) human liver and kidney cortex microsomes, and 2) Chinese hamster ovarian cells stably transfected with 11β-HSD1 or 11β-HSD2 expression vectors. Both systems produced concordant evidence for the following conclusions. Oxidation of steroids by 11β-HSD2 is diminished if they are fluorinated in position 6α or 9α (e.g. in dexamethasone) or methylated at 2α or 6α (in methylprednisolone) or 16α or 16β, by a methylene group at 16 (in prednylidene), methyloxazoline at 16, 17 (in deflazacort), or a 2-chlor configuration. Whereas the methyl groups also decrease reductase activity (steric effects), fluorination increases reductase activity (negative inductive effect), leading to a shift to reductase activity. This may explain the strong MC activity of 9α-fluorocortisol and should be considered in GC therapy directed to 11β-HSD2-expressing tissues (kidney, colon, and placentofetal unit). 11β-HSD2 oxidation of prednisolone is more effective than that of cortisol, explaining the reduced MC activity of prednisolone compared with cortisol. Reduction by 11β-HSD1 is diminished by 16α-methyl, 16β-methyl, 2α-methyl, and 2-chlor substitution, whereas it is increased by the Δ1-dehydro configuration in prednisone, resulting in higher hepatic first pass activation of prednisone compared with cortisone. To characterize a GC or a MC as substrate for the different 11βHSDs may be essential for an optimized steroid therapy.

Logical frameworks and meta-languages are intended as a common substrate for representing and implementing a wide variety of logics and formal systems. Their definition and implementation have been the focus of considerable work over the last decade. At the heart of this work is a quest for generality: A logical framework provides a basis for capturing uniformities across deductive systems and support for implementing particular systems. Similarly a meta-language supports reasoning about and using languages.Logical frameworks have been based on a variety of different languages including higher-order logics, type theories with dependent types, linear logic, and modal logic. Techniques of representation of logics include higher-order abstract syntax, inductive definitions or some form of equational or rewriting logic in which substitution is explicitly encoded.Examples of systems that implement logical frameworks include Alf, Coq, NuPrl, HOL, Isabelle, Maude, lambda-Prolog and Twelf. An active area of research in such systems is the study of automated reasoning techniques. Current work includes the development of various automated procedures as well as the investigation of rewriting tools that use reflection or make use of links with systems that already have sophisticated rewriting systems. Program extraction and optimization are additional topics of ongoing work.

This research sheds light on three essential issues for those dealing with the dilemmas of contemporary Islamic economics. The first concerns legal stratagems (hiyal): their types, their legitimacy and the effect of the motive for using them on the legal ruling. The second concerns combining the opinions of more than one madhab (talfīq), its relation to the issue of pursuing allowances (tatabbu’ al-rukhas) in the contemporary era and the parameters that must be observed when choosing the allowances of scholars. The third is the issue of adopting overruled (marjūh) opinions and abandoning the weighty (rājih) ones in the famous juristic schools (madhhabs). The conditions are identified which must be fulfilled in order for adoption of an overruled opinion to be taken seriously. The researcher used an inductive descriptive method by gathering the material relevant to the issues, arranging it logically, and providing explanations as needed to clarify the importance of these issues in regulating the Islamic banking industry. The researcher has discussed a few contemporary applications related to these issues, clarifying the differing views of contemporary jurists in understanding them. The researcher has found that there is a difference between legal stratagems to circumvent the Sharī‘ah and facilitating people’s affairs by searching for legitimate solutions (makhārij). This can be discerned by the motive for the contract and the circumstantial evidence that clarifies that motive and provides a basis for judgment upon it. Moreover, it is found that talfīq is not totally forbidden; in fact, current reality with its complications requires scholars to expand their selections. It also turns out that some jurists’ independent judgments are not within the scope of talfīq, as was thought by some scholars. The scholars’ selection of some of the marjūh opinions in the madhhabs must be methodical, according to certain rules, and this selection ultimately depends on legitimate benefit that is approved by the majority of scholars.

The demand for a local oscillator (LO) signal of high quality and integrity in local area network (WLAN) communication is growing with the increasing date rate. The LO signals for high data rate WLAN applications are desired to not only have proper shape waveforms and adequate voltage amplitude but also to achieve relatively stable and clean outputs with low phase noise and low spur. Fractional-N frequency planning is critical for a quadrature LO-generator, which is achieved by a single-sideband (SSB) mixer and multiple dividers since it can avoid the frequency pulling and alleviate the self-mixing and DC offset issues, while spur levels are easily increased due to harmonic mixing, imbalance, and leakage of the SSB mixer. This article proposes a simple and innovative quadrature LO-generator, which adopts a current-mode-logic (CML) inductive peaking (IP) circuit to improve phase noise and suppress spurious tones. Four types of LO delivery methods using IP circuits are proposed and compared. Among four methods, the CML-IP circuit presents the optimum performance for driving long wires of multi-mm length. Instead of previous digital spur cancellation, the CML-IP circuit achieves higher spur suppression, lower jitter, and a greater figure of merit (FoM). The quadrature LO-generator can be configured to either VCO mode or bypass mode supporting external VCO input. Implemented in 55 nm CMOS technology, the proposed quadrature LO-generator achieves −52.6 dBc spur suppression, −142 dBc/Hz phase noise at 1 MHz offset at the 4.8 GHz frequency, and −271 FoM. Furthermore, the quadrature LO-generator occupies an active area of 0.178 mm2 and consumes 23.86 mW.

The Bulk Synchronous Parallel ML (BSML) is a functional language for BSP programming, a model of computing which allows parallel programs to be ported to a wide range of architectures. It is based on an extension of the ML language by parallel operations on a parallel data structure called parallel vector, which is given by intention. We present a new approach to certifying BSML programs in the context of type theory. Given a specification and a program, an incomplete proof of the specification (of which algorithmic contents corresponds to the given program) is built in the type theory, in which gaps would correspond to the proof obligation. This development demonstrates the usefulness of higher-order logic in the process of software certification of parallel applications. It also shows that the proof of rather complex parallel algorithms may be done with inductive types without great difficulty by using existing certified programs. This work has been implemented in the Coq Proof Assistant, applied on non-trivial examples and is the basis of a certified library of BSML programs.

If a company wants to succeed in a tough competitive environment, it must consider all the options to be more visible. One of these possibilities is advertising, which exists in a considerable variety of forms. Therefore, our goal was to conduct a survey on the attitude of customers in Slovakia to several modern and traditional forms of advertising, which are used by companies for their visibility. Data were obtained from the questionnaires filled in by 244 respondents. We were interested in opinions on advertising oversaturation, the influence of advertising, annoyance by advertising, and credibility of advertising. In each of four topics, we investigated opinions on 21 different types of advertising, using non-parametric tests to determine the significance of differences, which means we used inductive statistics. According to respondents, the advertising on social networks has a higher influence than most other types of advertising. At the same time, it is not one of the most trusted forms, nor one of the most bothering forms. The right marketing strategy choice concerning time, money, form, and efficiency is a key factor to companies. Therefore, it is important for companies to use the right form or combination of forms of advertising to make themselves known depending on the type of product and its target group. To increase the sustainability of a company in the market, it is important to use the right form or combination of forms of advertising considering the product and the target group.

Actuality of the topic and scientific problem.Many researchers and practitioners have already begun to discuss the diversity of opinions regarding what constitutes an SC approach. Whilst there is a broad consistency in general opinion,there are also growing concerns regarding the apparent misinterpretation of the “ingredients” of SCL and what SCL actually looks like in practice. A student-centred classroom is not a place where students decide what they want to learn and what they want to do. It is a place where we consider the needs of the students, as group and as individuals, and encourage them to participate in the learning process all the time(Jones, 2007). It is noted that after the analysis of Bologna process documents and scientific literature, using a logical inductive method to purify the essential criteria, which makes it possible to assess the role of teacher to student oriented approach. The results revealed that the role of the teacher in order to ensure the quality of higher education is significant because the training (learning) paradigm shift opens up the possibility of the teacher to change the style of work, continuous improvement, however, and require a larger time-consuming.The purpose of the article analyzes the transition to student-oriented learning experiences and challenges. Methods:literature and document analysis and synthesis, analysis of legal documents, comparative, logical and inductive generalization methods.Results. The research describes the most frequent types of student-centred learning such as problem-based learning, project-led education, learning contracts, flexible learning, inquiry learning, just-in-time checking and personalized learning.Сonclusions. This research presents opinions of relevant authors on the contemporary student-centered learning and enables an insight into the practice of lecturers. It shows that SCL has got its place in European universities however several of its aspects should be developed further.

This paper presents the traveling wave based fault location methods of SEL-400L, and SFL-2000 available on the market for a 66.9km, 220kV Hoa Khanh-Thanh My transmission line in Central Viet Nam, such as single-ended, and double-ended, all of which rely on measurements from inductive CTs and capacitive VTs. Focus was given on the building process of a Matlab Simulink model to evaluate these methods. Current and voltage signals were sent to an analog Chebyshev type II filter which passes higher frequency signals at 3kHz and rejects low frequencies signal at 50Hz. After that, these output signals are used in Clarke's transformation for getting 0 and α components. The detail coefficient of the selected components after DWT using Db4 wavelet at decomposition level 1 can be used to determine the fault types, the direction of fault and propose a crest-wave comparison solution to identify exactly the adjacent bus' reflected wave from the fault point's reflected wave for the fault location. Finally, the accuracy of fault location on the transmission line is reviewed by varying various parameters like fault type, fault location and fault resistance on a given power system model.

In Latvia, the learners of secondary school as a requirement gets acquainted with basics of research – selection of literature, data collection and processing, communication and presentation skills.The present article deals with an analysis of the themes and texts (corpus) of the research papers (RP) in Health Science worked out by the authors of the top-ranked RP presented in the Scientific Conference of High School Learners of Latvia from 2016 to 2019. A logical inductive content analysis of features specific to each RP, and sequential categorization and grouping into a higher level of components were performed. The quantitative data were processed by using AntConc, IBM SPSS Statistics 22 and Microsoft Excel software.The aim of the research was to find out the themes and content variations of RP, and the characteristics of the language – tokens, types and keywords.The results show that there is a thematic uniformity in RP. The statistical characteristics of language differ in terms of lexical diversity and the frequency of keywords and their collocations. Mostly individual keywords dominate.The results obtained can be used to develop recommendations for learners and teachers as a model for theme selection, presentation of research and criteria for evaluating RP.

A growing series of news platforms such as live blogging, tweeting, and push notifications are struggling with the extreme pressure of immediate reporting. The current study explores which strategies of knowledge acquisition and knowledge presentation journalists who operate immediate channels are using to address the mounting pressures and enhanced risk of error. It focuses on online news flashes that at least in the Israeli case enable systematic comparison of four types of output: routine and crisis news flashes and routine and crisis final items that follow them. Findings show that news flash editors develop special practices to acquire and present knowledge – the most prominent being minimization of knowledge claims. However, significantly higher use of modality, evidentiality, and source responses (measures for minimizing journalists’ knowledge claims) was found only in crisis flashes. This may suggest that journalists find themselves outside their epistemic comfort zone only under the convergence of crisis and immediacy. According to ‘inductive error’ theory, the studied websites act as responsible epistemic actors, who are so concerned about ‘false-positive’ errors (untrue publications) that they do not hesitate to make ‘false-negative’ ones (delaying publication, minimizing knowledge claims, and sharing them with third parties).
