The concept of a hypersoft membership function is introduced in the extension of a soft set known as a hypersoft set, permitting it to handle complicated and uncertain information in a more powerful and flexible manner. Many academics have already become fascinated with this new area of study, leading to the development of a number of hybrid structures. This chapter develops some new hybrid hypersoft set structures by taking into account multiple fuzzy set-like settings and possibility degree-based settings collectively. Additionally, (...) numerical examples are included to clarify the concept of these structures. Researchers can utilize this work to better understand and apply a variety of mathematical ideas.

Wealth distribution based on classic sugarscape model leads to a population increase and the Gini coefficient decrease when cooperation and communication parameters are taken into account. In another study, this model was developed by implying a receipt of one-fifth of the assets of the population and derived utilization for poor people. The results showed a relation between mortality decrease, population increase, and Gini coefficient decrease (equality increase). In a synergic process, the wealth adjustment based on sugarscape model underwent some experiments (...) by implying communication and cooperation, and the mechanism of receiving and utilizing the assets. The results show that the population increase and the Gini coefficient decrease play an important role in wealth adjustment. (shrink)

Organised into three sections covering the place of semantics in linguistics, the description of sentence and word meanings, and current theoretical approaches to semantics, this book is aimed at undergraduates as well as general readers.

Lincoln and Guba provided some principles and four evaluative criteria called “trustworthiness” to guide social science research naturalistically. However, drawing on Science and Technology Studies (STS) literature, a field engaged with methods and practices of science for several decades, one can argue that this approach is not still fully naturalistic. In this paper, we review Lincoln and Guba’s four criteria of trustworthiness from an STS perspective. We argue that the STS literature can challenge these criteria, but at the same time (...) they have the potential to be reconstructed with the help of the materials STS provides. (shrink)

Neonatal brain monitoring in the neonatal intensive care units requires a continuous review of the spontaneous cortical activity, i.e., the electroencephalograph background activity. This needs development of bedside methods for an automated assessment of the EEG background activity. In this paper, we present development of the key components of a neonatal EEG background classifier, starting from the visual background scoring to classifier design, and finally to possible bedside visualization of the classifier results. A dataset with 13,200 5-minute EEG epochs from (...) 27 infants with birth asphyxia was used for classifier training after scoring by two independent experts. We tested three classifier designs based on 98 computational features, and their performance was assessed with respect to scoring system, pre- and post-processing of labels and outputs, choice of channels, and visualization in monitor displays. The optimal solution achieved an overall classification accuracy of 97% with a range across subjects of 81–100%. We identified a set of 23 features that make the classifier highly robust to the choice of channels and missing data due to artefact rejection. Our results showed that an automated bedside classifier of EEG background is achievable, and we publish the full classifier algorithm to allow further clinical replication and validation studies.

Managing non-communicable diseases in crisis-affected and fragile humanitarian contexts requires special attention because primary health care systems often collapse or become compromised in such settings. As a result, addressing and managing these diseases become more challenging. Humanitarian organizations that intervene in crisis situations are increasingly including NCD management in the services they support and provide; however, they encounter a range of issues such as ensuring the quality of care, sustainability of programs, and the possibility of unintended harms. This case study (...) explores ethical considerations raised by a mobile NCD program run by an international humanitarian organization in a country affected by a protracted civil war. (shrink)

In these two long-distance interviews, Iranian Saeed Naji, founder of the Philosophy for Children movement in Iran, questions two veteran practitioners of philosophy for children/community of philosophical inquiry . He raises issues related to P4C/CPI as representative of a larger educational paradigm, which he calls “reflective education,” and weighs its prospects for replacing what he calls the “traditional paradigm” worldwide. He also queries the two scholars on issues such as criteria for appropriate texts/stimuli for practicing philosophy with children; issues (...) around teacher preparation; the epistemological paradigm of CPI and its relation to the logic of scientific discovery and mathematical proof; the status of CPI as a “new” or reconstructed form of the discipline of philosophy; the prospects for a narrative approach to philosophy as exemplified in the new literary genre of the Lipmanian philosophical novel for children; the relationship between the practice of CPI in schools and the possibility for educational reconstruction, particularly in the area of social democracy and school governance; the significance of understanding the child as a “privileged stranger” to patriarchal colonialist culture, and the social implications of a form of education based on dialogue rather than forced enculturation; and the implications for the construction and delivery of curriculum in a school in which CPI and emergent curriculum were central organizational elements.

The proofs of Kleene, Chaitin and Boolos for Gödel's First Incompleteness Theorem are studied from the perspectives of constructivity and the Rosser property. A proof of the incompleteness theorem has the Rosser property when the independence of the true but unprovable sentence can be shown by assuming only the (simple) consistency of the theory. It is known that Gödel's own proof for his incompleteness theorem does not have the Rosser property, and we show that neither do Kleene's or Boolos' proofs. (...) However, we show that a variant of Chaitin's proof can have the Rosser property. The proofs of Gödel, Rosser and Kleene are constructive in the sense that they explicitly construct, by algorithmic ways, the independent sentence(s) from the theory. We show that the proofs of Chaitin and Boolos are not constructive, and they prove only the mere existence of the independent sentences. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Providing Care to a Potential Aggressor: An Ethical DilemmaHandreen Mohammed SaeedFollowing the abrupt fall of almost a third of its territory in 2014 to armed militias, Iraq fell into civil war turmoil. As a direct result of the armed conflicts, hundreds of thousands of Iraqis were displaced or subjected to atrocious human rights violations with physical, sexual, and psychosocial abuse. While the scenes on the TV provided only a (...) glimpse of what was happening on the ground, the true stories circulating about people’s suffering left me personally in absolute shock. Among those who suffered the most from the offences were marginalized religious and ethnic minority groups, who were viewed and treated as infidels by the aggressor militants. Those marginalized communities not only endured displacement due to the armed conflicts but they were also mass-exterminated, sexually abused, and underwent massive destruction of their towns and villages.In 2016, I was working for Ministry of Health as a primary care physician in a small town in Iraqi Kurdistan, which hosted tens of thousands of internally displaced people (IDPs) from one of those marginalized minority communities. I had the opportunity to hear their tragic stories firsthand as they fled for their lives in 2014. Working in those communities as a primary care physician allowed me to truly understand their feelings and emotions and reflect on their experiences while providing healthcare services. This experience sparked an interest in humanitarian work, in which I could be close to areas of need and involved in providing physical health first-aid and also psychological and social first-aid; all crucial in addressing the future health consequences experienced by people going through humanitarian crises. In the same year, 2016, I joined an international medical organization and started working in remote and low-resource settings in northern Iraq as a humanitarian physician. Our projects included a variety of primary care, psychosocial, and urgent care services targeting refugees, IDPs, and vulnerable host communities in areas near conflict zones. The projects were designed and implemented with the hope that the most vulnerable populations have access to our services.In October 2016, the Iraqi authorities launched a massive military operation known as the “Battle of Mosul” to regain control of Mosul, the second-largest city in Iraq. As an emergency medical humanitarian organization, we had to be near the battlefield and respond to the unfolding humanitarian crisis on a daily basis. As the official security forces backed by the international alliance started to advance, tens of thousands of people, including some militants and their families, fled Mosul and headed towards areas controlled by the Kurdistan Regional Government’s forces in the north, where our organization was operational. Some of them sought refuge in one of our medical facilities in northern Iraq, which was operated by local staff, [End Page 172] including members from some of the minority communities that had suffered the most from the militants’ aggression in 2014. The patients entering our facilities were mainly older adults, women, and children, but we were also visited by a small group of potential militants who were either injured, malnourished, or just seeking help and refuge. As a neutral, impartial, independent, humanitarian organization compliant with medical ethics, we were committed to providing healthcare services to anybody in need without discrimination or judgment.As we responded to the humanitarian crisis unfolding before our eyes, some of our staff members came forward and raised valid questions about the ethics of treating patients potentially involved in serious human rights violations. With tears in her eyes, one nurse approached me and stated, “Seeing these people reminds me of all the girls and women who went missing from my village and are now being sold as sex slaves in Syria”. The staff expressed serious concerns about their ability to provide care to patients who may have been involved in mass killing, torture, and the destruction of their own towns, as well as sexual abuse against their family members, friends, and people in their communities. Due to the psychological and physical trauma caused by the militants’ conquest, the staff was reluctant to provide medical care to these patients, as seeing and hearing them brought back... (shrink)

A cornerstone of modern mathematical logic is the diagonal lemma of Gödel and Carnap. It is used in e.g. the classical proofs of the theorems of Gödel, Rosser and Tarski. From its first explication in 1934, just essentially one proof has appeared for the diagonal lemma in the literature; a proof that is so tricky and hard to relate that many authors have tried to avoid the lemma altogether. As a result, some so called diagonal-free proofs have been given for (...) the above mentioned fundamental theorems of logic. In this paper, we provide new proofs for the semantic formulation of the diagonal lemma, and for a weak version of the syntactic formulation of it. (shrink)

We argue that, under the usual assumptions for sufficiently strong arithmetical theories that are subject to Gödel’s First Incompleteness Theorem, one cannot, without impropriety, talk about *the* Gödel sentence of the theory. The reason is that, without violating the requirements of Gödel’s theorem, there could be a true sentence and a false one each of which is provably equivalent to its own unprovability in the theory if the theory is unsound.

Martin Buber has always made it clear that his dialogic principle is not to be treated as an abstract conception but an ontological reality. But admittedly, in I And Thou he could only point to such reality and could not properly present it in discursive prose. However there are instances in the text where he strives to do the latter. One particular instance is where he elaborates the emergence of consciousness of “I”. Through this elaboration, what Buber has tried to (...) point at is the bringing forth of the primary word ‘I-It’ forming part of his dialogic principle, as it ‘emerges round about’ the perceptual consciousness realised in body as some sort of a ‘primitive function of knowledge’. However, this still amounts only to an abstract conception, and not to a description of ontological reality as Buber would have aspired for. Hence the thought: what if there exists an endeavour carried out independently of Buber’s work, nevertheless in the same spirit as Buber but without his notorious mixing up of philosophy and religion? There indeed has been such an Existential-phenomenological take on embodiment and perception by the French phenomenologist Maurice Merleau-Ponty, as is laid out in his magnum opus Phenomenology of Perception. In the present paper we will explicate this interesting coincidence, thereby honouring Buber’s aspiration for ontological status to his dialogic principle, at the same time demonstrating how existentially resonating and ontologically converging the thought of these two great thinkers’ have been, though they had totally different intellectual pursuits and concerns.

This study linked background TV and socioeconomic status to minority children’s Persian vocabulary development. To this end, 80 Iranian preschool children from two minority groups of Arabs and Turks were selected using stratified random sampling. They were simultaneous bilinguals, i.e., their mother tongue was either Arabic or Azari and their first language was Persian. Language sample analysis was used to measure vocabulary development through a 15-min interview by language experts. The LSA measures included total number of utterances, total number of (...) words, total number of new words, and mean length of utterance. A series of independent-samples t test, paired-samples t test, and repeated measures MANOVA tests were ran to examine data. Results showed significant improvements in children’s vocabulary scores from pretest to posttest for all children. In addition, high-SES children scored higher on the vocabulary measures in pretest and posttest. Moreover, background TV was associated with higher means in the TNW and the NDW in groups. The researchers concluded that background TV may be related to higher vocabulary scores in low-SES families as it may compensate for some linguistics gaps in these families including lower amount of child-parent interaction, play, and parents’ level of literacy.

Background:Experiencing moral distress is traumatic for nurses. Ignoring moral distress can lead to job dissatisfaction, improper handling in the care of patients, or even leaving the job. Thus, it is crucial to use valid and reliable instruments to measure moral distress.Objective:The purpose of this study was to determine the reliability and the validity of the Persian version of the Moral Distress Scale–Revised among a sample of Iranian nurses.Research design:In this methodological study, 310 nurses were recruited from all hospitals affiliated with (...) the Qazvin University of Medical Sciences from February 2014 to April 2015. Data were collected using a demographic questionnaire and the Moral Distress Scale–Revised. The construct validity of the Moral Distress Scale–Revised was evaluated using principal component analysis and confirmatory factor analysis. Internal consistency reliability was assessed with Cronbach’s alpha.Ethical considerations:This study was approved by the Regional Committee of Medical Research Ethics. The ethical principles of voluntary participation, anonymity, and confidentiality were considered.Findings:The construct validity of the scale showed four factors with eigenvalues greater than one. The model had a good fit ( χ2(162) = 307.561, χ2/ df = 1.899, goodness-of-fit index =.904, comparative fit index =.927, incremental fit index =.929, and root mean square error of approximation (90% confidence interval) =.049 (.040–.057)) with all factor loadings greater than.5 and statistically significant. Cronbach’s alpha coefficients were.853,.686,.685, and.711for the four factors. Moreover, the model structure was invariant across different income groups.Discussion and conclusion:The Persian version of the Moral Distress Scale–Revised demonstrated suitable validity and reliability among nurses. The factor analysis also revealed that the Moral Distress Scale–Revised has a multidimensional structure. Regarding the proper psychometric characteristics, the validated scale can be used to further research about moral distress in this population. (shrink)

Pessimistic meta-induction is a powerful argument against scientific realism, so one of the major roles for advocates of scientific realism will be trying their best to give a sustained response to this argument.

This (...) essay aims to present what we call expansive structures, which are the structures that can be reconstructed from geometrized Newtonian gravitation and are capable of expanding into general relativity, explicitly.

It is shown that all the provably total functions of Basic Arithmetic BA, a theory introduced by Ruitenburg based on Predicate Basic Calculus, are primitive recursive. Along the proof a new kind of primitive recursive realizability to which BA is sound, is introduced. This realizability is similar to Kleene's recursive realizability, except that recursive functions are restricted to primitive recursives.

Interesting as they are by themselves in philosophy and mathematics, paradoxes can be made even more fascinating when turned into proofs and theorems. For example, Russell’s paradox, which overthrew Frege’s logical edifice, is now a classical theorem in set theory, to the effect that no set contains all sets. Paradoxes can be used in proofs of some other theorems—thus Liar’s paradox has been used in the classical proof of Tarski’s theorem on the undefinability of truth in sufficiently rich languages. This (...) paradox (as well as Richard’s paradox) appears implicitly in Gödel’s proof of his celebrated first incompleteness theorem. In this paper, we study Yablo’s paradox from the viewpoint of first- and second-order logics. We prove that a formalization of Yablo’s paradox (which is second order in nature) is non-first-orderizable in the sense of George Boolos (1984). (shrink)

We take an argument of Gödel's from his ground‐breaking 1931 paper, generalize it, and examine its validity. The argument in question is this: "the sentence G says about itself that it is not provable, and G is indeed not provable; therefore, G is true".

We prove the equivalence of the semantic version of Tarski’s theorem on the undefinability of truth with the semantic version of the diagonal lemma and also show the equivalence of a syntactic version of Tarski’s undefinability theorem with a weak syntactic diagonal lemma. We outline two seemingly diagonal-free proofs for these theorems from the literature and show that the syntactic version of Tarski’s theorem can deliver Gödel–Rosser’s incompleteness theorem.

To investigate the effect of philosophical thinking on the development of reasoning skills and behavioral performance among Iranian primary school students, we conducted a qualitative method study with ten fourth grade students (including boys and girls)selected from different primary schools in Tehran1.

This study was carried out in the Institute for Humanities and Cultural (...) Studies, as an extra class once a week for twenty sessions. Data collection strategies of this study including the authors’ observations during sessions, children’s parents’ observations and reports, and interviews with children and their parents. Our research result shows that reasoning skills enhance communication skills by enabling children to express their ideas more persuasively. We also found that children act more confidently and independently. (shrink)

One way to compare different theoretical approaches to the study of technologies is to see what the difference is between their narratives of the construction of a particular technology. In this paper, we re-narrate the bicycle construction from the perspective of actor-network theory (ANT), comparing to SCOT’s first account of the construction. Although SCOT has moved closer to actor-network theory later by paying more attention to co-construction and materliaty, Pinch and Biker have not modified their account of the bicycle development (...) according to these theoretical changes, despite the fact that one decade later Bijker allocated one chapter, ‘king of the road’, to Safety bicycle development again. An ANT’s narrative of bicycle development can provide a basis for a concrete comparison between ANT and the classic version of SCOT. Or it could be argued that this narrative could complement the story of Pinch and Biker of bicycle development. While we present a new narrative of bicycle development in comparison with SCOT’s one, we offer a methodological framework in the ANT literature that can be considered as a methodological procedure to the study of artefacts in general; this framework has three elements: 1. Phenomenal Bracketing, 2. Collective construction, and 3. Co-construction. (shrink)

This study examined the influence of ethical leadership on knowledge sharing, the mediating role of psychological ownership, and the moderating effect of professional commitment between ethical leadership and knowledge sharing. Data were collected from 307 public listed Pakistani companies’ employees. Statistical analyses were performed by using SPSS Version 25 and AMOS version 22. The findings indicate a positive relationship between EL and KS behavior. Additionally, the impact of EL on KS was partially mediated by psychological ownership. Furthermore, professional commitment buffers (...) the link between EL and KS. This study contributes to the body of knowledge in the field of leadership by confirming the role of ethics. The results show that ethical leaders develop employee attitudes that contribute to employee KS behavior. Ethical leaders create and encourage a learning culture to enhance organizational performance. This study adds to the little data on the positive impact of EL on listed company’s employees and addresses the gaps in previous studies on the role of EL in changing environments. In addition, professional commitment as a moderator has not been previously investigated with ethical leadership antecedents. (shrink)

A growing body of work suggests that the presence of women and of independent directors on boards of directors is associated with higher corporate environmental performance. However, the mechanisms linking board composition to corporate environmental performance are not well understood. This study proposes and empirically tests the mediating role of sustainability-themed alliances in the relationship between board composition and corporate environmental performance. Using the population of public oil and gas firms in the United States as the sample, the study relies (...) on renewable energy alliances to measure sustainability-themed alliances and longitudinally analyzes lagged data for independent and control variables. The study found that the higher the representation of women on a firm’s board, the more likely the firm is to form sustainability-themed alliances, and the higher the representation of independent directors on a firm’s board, the more likely the firm is to form sustainability-themed alliances. Such alliances, in turn, positively contribute to corporate environmental performance. This paper discusses the study’s contributions to the board composition-social performance literature. (shrink)

We demonstrate that, in itself and in the absence of extra premises, the following argument scheme is fallacious: The sentence A says about itself that it has a property F, and A does in fact have the property F; therefore A is true. We then examine an argument of this form in the informal introduction of Gödel’s classic (1931) and examine some auxiliary premises which might have been at work in that context. Philosophically significant as it may be, that particular (...) informal argument plays no rôle in Gödel’s technical results. Going deeper into the issue and investigating truth conditions of Gödelian sentences (i.e., those sentences which are provably equivalent to their own unprovability) will provide us with insights regarding the philosophical debate on the truth of Gödelian sentences of systems—a debate which goes back to Dummett (1963).

The Omani socio-cultural context, the mono-gender educational system in schools, and the learning environment at the higher educational institutions significantly affect learners' self-efficacy and academic achievement in the mixed-gender EFL classroom. Different studies have revealed both positive and negative implications of mixed-gender classrooms, especially for those who came from a mono-gender learning environment. The adjustment phase for the tertiary learners from school to the university is not only crucial but also significant for the continuation of higher education. The effects of (...) socio-cultural factors on self-efficacy and academic achievement have not been studied in depth, particularly in eastern countries. So, the current study aimed at investigating the role of gender, learning background, socio-cultural circumstances, and the effect of the learning environment on EFL learners' self-efficacy and their academic achievement within the scenario of the prevailing culture and traditions in the Dhofar Region. To conduct this study, mixed research methods have been adopted to investigate the perceptions of both teachers and learners. The sample of the study consists of 117 EFL learners ranging between 18–22 years of age and 25 EFL teachers ranging between 35–60 years of age. We used separate surveys for students and the teachers and interviewed students and teachers on a random basis. The results demonstrate that both genders were comfortable in segregated classes. The results also reveal that female learners were active learners and better performers than male learners in the school learning environment. The students reported that social restrictions discouraged them from mixing with the opposite gender in classroom activities and oral discussions. Most teachers believe that, compared to male learners, female learners performed better and were more engaged and responsive to different learning situations. The study found that there were statistically significant differences between both genders in terms of the effects of socio-cultural environment, self-efficacy, and the learning environment. Female learners were better than male learners in mono-gender schools, and they have higher self-efficacy than male students at the university. In conclusion, EFL teachers should consider the socio-cultural context, learners' learning background, and other challenges of learners to bring out positive outcomes in a mixed-gender classroom.

Building on social information processing theory and social exchange theory, this research advances the emerging concept of work engagement and inclusive leadership. Surprisingly, there is no study linking work engagement and inclusive leadership style in the setting of multiple organizations in China. The main purpose of this study is to identify the effective leadership style affecting work engagement directly and indirectly through psychological safety. The trust in leader further moderated the direct relationships. Using multi-source data of 390 responses from leaders-subordinates (...) dyads working in 20 Chinese companies (which include textile, manufacturing, construction, and trading), this study tested how inclusive leadership increased the work engagement of their subsequent subordinates. The mediating role of psychological safety and moderating role of trust in leader therein. The findings introduced an interactive motivational framework that revealed the positive influence of inclusive leadership on the work engagement of subordinates. Further, psychological safety mediated the direct relationship between inclusive leaders and work engagement. The role of trust in leader strengthened the direct relationship of inclusive leadership with psychological safety and work engagement. This is among the first studies to integrate inclusive leadership, psychological safety, trust in leader, and work engagement into a single interactive framework. Further, it provides empirical evidence in the context of predicting and increasing the work engagement of subordinates. (shrink)

We investigate the impact of women shareholders on corporate social responsibility (CSR) and how they interact with women directors to exert a greater influence on CSR activities. Little is known about how women's ownership can enhance their roles in CSR practices. Based on data from Omani-listed firms during 2016–2020 and using CSR budgeting and spending as proxies for CSR activities, firms with women shareholders allocate more CSR budgeting and spend more money on CSR activities. However, we also find that women (...) directors can only affect CSR budgeting and spending if their representation on the board is increased. Furthermore, we find that firms with women shareholders and directors have higher CSR budgeting and spending. Further analysis reveals that women shareholders are more likely to spend money on CSR activities within the budgeted amount and are less likely to be associated with gaps between CSR budgeting and spending. This analysis also shows that the type of ownership (family versus non-family) influences women shareholders' effects on CSR budgeting and spending. Our empirical findings provide critical insights into how woman shareholders influence CSR actions. (shrink)

The Theme. Strong forcing axioms like Martin’s Maximum give a reasonably satisfactory structural analysis of $H(\omega _2)$. A broad program in modern Set Theory is searching for strong forcing axioms beyond $\omega _1$. In other words, one would like to figure out the structural properties of taller initial segments of the universe. However, the classical techniques of forcing iterations seem unable to bypass the obstacles, as the resulting forcings axioms beyond $\omega _1$ have not thus far been strong enough! However, (...) with his celebrated work on generalised side conditions, I. Neeman introduced us to a novel paradigm to iterate forcings. In particular, he could, among other things, reprove the consistency of the Proper Forcing Axiom using an iterated forcing with finite supports. In 2015, using his technology of virtual models, Veličković built up an iteration of semi-proper forcings with finite supports, hence reproving the consistency of Martin’s Maximum, an achievement leading to the notion of a virtual model.In this thesis, we are interested in constructing forcing notions with finitely many virtual models as side conditions to preserve three uncountable cardinals. The thesis constitutes six chapters and three appendices that amount to 118 pages, where Section 1 is devoted to preliminaries, and Section 2 is a warm-up about the scaffolding poset of a proper forcing. In Section 3, we present the general theory of virtual models in the context of forcing with sets of models of two types, where we, e.g., define the “meet” between two virtual models and prove its properties.The main results are joint with Boban Veličković, and partly appeared in Guessing models and the approachability ideal, J. Math. Log. 21 (2021).Pure Side Conditions. In Section 4, we use two types of virtual models (countable and large non-transitive ones induced by a supercompact cardinal, which we call Magidor models) to construct our forcing with pure side conditions. The forcing covertly uses a third type of models that are transitive. We also add decorations to the conditions to add many clubs in the generic $\omega _2$. In contrast to Neeman’s method, we do not have a single chain, but $\alpha $ -chains, for an ordinal $\alpha $ with $V_\alpha \prec V_\lambda $. Thus, starting from suitable large cardinals $\kappa <\lambda $, we construct a forcing notion whose conditions are finite sets of virtual models described earlier. The forcing is strongly proper, preserves $\kappa $, and has the $\lambda $ -Knaster property. The relevant quotients of the forcing are strongly proper, which helps us prove strong guessing model principles. The construction is generalisable to a ${<}\mu $ -closed forcing, for any given cardinal $\mu $ with $\mu ^{<\mu }=\mu <\kappa $.The Iteration Theorem. In Section 5, we use the forcing with pure side conditions to iterate a subclass of proper and $\aleph _2$ -c.c. forcings and obtain a forcing axiom at the level of $\aleph _2$. The iterable class is closely related to Asperó–Mota’s forcing axiom for finitely proper forcings.Guessing Model Principles. Section 6 encompasses the main parts of the thesis. We prove the consistency of the guessing principle $\mathrm {GMP}^+(\omega _3,\omega _1)$ that states for any cardinal ${\theta \geq \omega _3}$, the set of $\aleph _2$ -sized elementary submodels M of $H(\theta )$, which are the union of an $\omega _1$ -continuous $\in $ -chain of $\omega _1$ -guessing, I.C. models is stationary in $\mathcal P_{\omega _3}(H(\theta ))$. The consistency and consequences of this principle are demonstrated in the following diagram. We also prove that one can obtain the above guessing models in a way that the $\omega _1$ -sized $\omega _1$ -guessing models remain $\omega _1$ -guessing model in any outer transitive model with the same $\omega _1$, and we denote this principle by $\rm{SGMP}^+(\omega_3,\omega_1)$.In the following diagram, $\mathrm{TP}$ stands for the tree property; $w\mathrm{KH}$ stands for the weak Kurepa Hypothesis; $\mathrm{MP}$ stands for Mitchell property, i.e., the approachability ideal is trivial modulo the nonstationary ideal; $\mathrm{AP}$ stands for the approachability property; $\mathrm {AMTP}(\kappa ^+)$ states that if $2^\kappa <\aleph _{\kappa ^+}$, then every forcing which adds a new subset of $\kappa ^+$ whose initial segments are in the ground model, collapses some cardinal $\leq 2^{\kappa }$. The dotted arrow denotes the relative consistency, while others are logical implications.Appendices. Appendix A includes merely the above diagram. Appendix B presents a proof of the Mapping Reflection Principle with finite conditions under $\mathrm {PFA}$. Appendix C contains open problems. Finally, the thesis’s bibliography consists of 42 items.Abstract prepared by Rahman MohammadpourE-mail: [email protected]: https://theses.hal.science/tel-03209264. (shrink)
