Discusses the phenomenological foundations for qualitative research in psychology which operates out of the intersection of phenomenological philosophy, science, and psychology; challenges long-standing assumptions about the practice of grounding the science of psychology in empiricism and asserts that the broader philosophy of phenomenological theory of science permits more adequate psychological development"--Provided by publisher.

This article points out the criteria necessary in order for a qualitative scientific method to qualify itself as phenomenological in a descriptive Husserlian sense. One would have to employ description within the attitude of the phenomenological reduction, and seek the most invariant meanings for a context. The results of this analysis are used to critique an article by Klein and Westcott , that presents a typology of the development of the phenomenological psychological method.

The author explains that his background was in experimental psychology but that he wanted to study the whole person and not fragmented psychological processes. He also desired a non-reductionistic method for studying humans. Fortunately he came across the work of Edmund Husserl and discovered in the latter’s thought a way of researching humans that met the criteria he was seeking. Eventually he developed a phenomenological method for researching humans in a psychological way based upon the work of Husserl and Merleau-Ponty. (...) This article briefly describes the method.

In adapting Husserl’s philosophical phenomenological method to conduct research in psychology I included Husserl’s two methodical steps, the epochē and the reduction, as part of the scientific procedure. Zahavi objected to my use of those steps. This article is a response to his objections and it is a reaffirmation of the necessity of the epochē and reduction for Husserlian phenomenological psychological research. A description of Husserl’s acknowledged types of psychology and a description of his transcendental phenomenology are also presented along (...) with two outlines of how Husserlian phenomenological research could be conducted.

In this article the phenomonelogical approach to qualitative research is compared with certain other qualitative approaches following other paradigms. The thesis is that a deepened understanding of phenomenological philosophy can provide the alternative framework that many of these authors have been seeking. The comparison with other approaches is made in terms of theoretical and methodical consistency. Theoretically, the argument is that the situation known as "mixed discourse" exists because practitioners have not sufficiently freed themselves from the criteria and practices of (...) traditional paradigms in which most qualitative researchers have been trained. The shift from the collection of numerical data to linguistic data takes place without appropriate shift in theoretical context. This state of affairs should be overcome in order to strengthen qualitative research. On the other hand, many qualitative researchers carry on practices that seem to be analogous to phenomenological prescriptions which are explicitly usually misunderstood or resisted when stated directly and generically. Thus, greater theoretical clarity and consistency as well as deeper reflection or better utilization of imaginative possibilities still seem to be called for in order to bring better theoretical conceptualization and more consistent practices to qualitative research.

Since the early 1990s, increasing attention has been paid to the impact of workplace bullying on employees’ well-being and job attitudes. However, the relationship between workplace bullying and job satisfaction remains unclear. This study aims to shed light on the nature of the bullying-job satisfaction relationship in the Italian context. As expected, the results revealed a U-shape curvilinear relationship between workplace bullying and job satisfaction after controlling for demographic variables. In contrast to the curvilinear model, the results support a negative (...) linear relationship between workplace bullying and psychological well-being, in which higher exposure to negative acts at work is associated with diminished well-being. In addition, gender and job position significantly predicted mental health scores where men and managers reported a better psychological well-being than women, blue-collar, and white-collar employees. Practical and theoretical implications are discussed according to these results. (shrink)

This work is an attempt to lay foundations for a theory of interactive computation and bring logic and theory of computing closer together. It semantically introduces a logic of computability and sets a program for studying various aspects of that logic. The intuitive notion of computational problems is formalized as a certain new, procedural-rule-free sort of games between the machine and the environment, and computability is understood as existence of an interactive Turing machine that wins the game against any possible (...) environment. The formalism used as a specification language for computational problems, called the universal language, is a non-disjoint union of the formalisms of classical, intuitionistic and linear logics, with logical operators interpreted as certain—most basic and natural—operations on problems. Validity of a formula is understood as being “always computable”, and the set of all valid formulas is called the universal logic. The name “universal” is related to the potential of this logic to integrate, on the basis of one semantics, classical, intuitionistic and linear logics, with their seemingly unrelated or even antagonistic philosophies. In particular, the classical notion of truth turns out to be nothing but computability restricted to the formulas of the classical fragment of the universal language, which makes classical logic a natural syntactic fragment of the universal logic. The same appears to be the case for intuitionistic and linear logics . Unlike classical logic, these two do not have a good concept of truth, and the notion of computability restricted to the corresponding two fragments of the universal language, based on the intuitions that it formalizes, can well qualify as “intuitionistic truth” and “linear-logic truth”. The paper also provides illustrations of potential applications of the universal logic in knowledgebase, resourcebase and planning systems, as well as constructive applied theories. The author has tried to make this article easy to read. It is fully self-contained and can be understood without any specialized knowledge of any particular subfield of logic or computer science.

This study was concerned with the clarification of the experience of pivotal moments in therapy. By pivotal moment is understood an event within the therapeutic process that leads to enduring change experienced as an important improvement in the life-experience of the client. Retrospective descriptions of a therapeutic process were obtained from three clients in which a distinguishable chain of events could be discerned that the clients identified as a pivotal moment. The descriptive material was analyzed according to the descriptive phenomenological (...) psychological method developed by Amedeo Giorgi on the basis of the philosophical phenomenology of Husserl and Merleau-Ponty. The results show that the pivotal moment is experienced as a figural moment within the therapeutic process where a serious challenge to old assumptions takes place, necessitating a break from old cognitive, affective and behavioral patterns in a context of trust and safety within the therapeutic relationship.

This article is a response to Jonathan Smith’s attempted rebuttal to the accusations I had made that Interpretative Phenomenological Analysis’s methodical procedures did not meet generally accepted scientific criteria. Each of Smith’s defenses was carefully examined and found to be lacking. IPA’s claim to have roots in contemporary phenomenological philosophy was found to be seriously deficient and its claim that it has a basis in hermeneutics was superficial. IPA’s hesitation to proclaim fixed methods makes the possibility of replication of IPA (...) studies impossible and thus it makes the fulfillment of an important scientific criterion impossible. Its claim that its findings are subjective fails to meet the important scientific criterion of objectivity or even intersubjectivity. Consequently, the claims that I made in my original article were basically sustained and repeated. (shrink)

In the contemporary scene, psychological researchers seeking alternative research strategies are turning increasingly toward interpretation theory. However, other strategies are also available, and one of these is descriptive science. Descriptive practices as the basis for the clarification of meanings have received less emphasis because of several epistemological assumptions about meaning that have appeared in the literature of interpretive science. Based upon the work of contemporary transcendental philosophers, especially J. N. Mohanty, this article argues that a descriptive scientific perspective can respond (...) to some of the hermeneutic arguments about meaning and that solid findings can be established descriptively. It is argued that both description and interpretation are legitimate but that they are tied to different conditions and interests. (shrink)

Recently, a book was published, the sole purpose of which was to discourage researchers from using the scientific phenomenological method. The author had previously been critical of nurses who had used the scientific phenomenological method but in the new book he goes after the originators of different methods of scientific phenomenological research and attempts to criticize them severely. In this review I defend only the scientific phenomenological method that is strictly based upon the thought of Edmund Husserl. Given the entirely (...) negative project of only critiquing phenomenologically grounded scientific research, one would expect the author to be sensitive to the cautions historians and philosophers of science speak about when one attempts to criticize concepts and procedures that belong to a different research community. Paley, an empiricist, uses empirical criteria to criticize phenomenological work.Moreover, given the entirely negative project of critiquing phenomenologically grounded scientific research one would expect the author to be knowledgeable about phenomenology and the innovative research practices used by a new research community. However, the author has only a thin, superficial understanding of phenomenology. One gets the impression that he only reads phenomenology in order to critique it. He displays an outsider’s understanding of it which means that his criticisms of it are faulty because he does not know how to think and dwell within the phenomenological framework; he does not understand “discovery-oriented” research and he keeps judging such research according to criteria from the “context of verification” perspective which are the wrong criteria for “discovery-oriented” research; he denigrates and reduces nursing research strategies because he interprets them to be based on pragmatic motivations only. He does not even grant that nurses can have authentic scientific motivations for seeking phenomenologically based methods; he uses unfair rhetorical strategies in the sense that he uses strategies himself that he criticizes when others use them. The review below documents what has been summarized here. (shrink)

This book considers the semantic and syntactic nature of indexicals - linguistic expressions, as in I, you, this, that, yesterday, tomorrow , whose reference shifts from utterance to utterance.There is a long-standing controversy as to whether the semantic reference point is already present as syntactic material or whether it is introduced post-syntactically by semantic rules of interpretation. Alessandra Giorgi resolves this controversy through an empirically grounded exploration of temporal indexicality, arguing that the speaker's temporal location is specified in the (...) syntactic structure. She supports her analysis with theoretical and empirical arguments based on data from English, Italian, Chinese, and Romanian. Professor Giorgi addresses some difficult and longstanding issues in the analysis of temporal phenomena - including the Italian imperfect indicative, the properties of the so-called future-in-the-past, and the properties of Free Indirect Discourse - and shows that her framework can account elegantly for all of them. Carefully argued, succinct, and clearly written her book will appeal widely to semanticists in linguistics and philosophy from graduate level upwards and to linguists interested in the syntax-semantics interface.

While it is heartening to see that more researchers in the field of the social sciences are using some version of the phenomenological method, it is also disappointing to see that very often some of the steps employed do not follow phenomenological logic. In this paper, several dissertations are reviewed in order to point out some of the difficulties that are encountered in attempting to use some version of the phenomenological method. Difficulties encountered centred on the phenomenological reduction, the use (...) of imaginative variation and the feedback to subjects.

The concept of scaffolding has wide resonance in several scientific fields. Here we attempt to adopt it for the study of development. In this perspective, the embryo is conceived as an integral whole, comprised of several hierarchical modules as in a recurrent circularity of emerging patterns. Within the developmental hierarchy, each module yields an inter-level relationship that makes it possible for the scaffolding to mediate the production of selectable variations. A wide range of genetic, cellular and morphological mechanisms allows the (...) scaffolding to integrate these modular variations into a functionally coordinate unit. A genetic scaffolding accounts for the inherited invariance of pattern formation during the embryo’s growth. At higher level, cells behave as agents endowed with the capacity to interpret any scaffolding variation as signs. The full hierarchy of a multi-level scaffolding is eventually attained when the embryo acquires the capacity to impose a number of developmental constraints on its constituting parts in a top-down direction. The acquisition of this capacity allows a semiotic threshold to emerge between the living cellular world and the underlying non-living molecular world. As this boundary is gradually defined during development, cells enter into new functional relationships, while, at the same time, are relieved from their physical determinism. The resulting constraints can thus become the driving forces that upgrade embryonic scaffolding from the simple molecular signalling to the complexity of sign recognition proper of a cellular community. In this semiotic perspective, the apparent goal directness of any developmental strategy should no longer be accounted for by a predetermined genetic program, but by the gradual definition of the relationships selected amongst the ones historically explored.

The paper gives a soundness and completeness proof for the implicative fragment of intuitionistic calculus with respect to the semantics of computability logic, which understands intuitionistic implication as interactive algorithmic reduction. This concept — more precisely, the associated concept of reducibility — is a generalization of Turing reducibility from the traditional, input/output sorts of problems to computational tasks of arbitrary degrees of interactivity.

Computability logic (CL) is a recently launched program for redeveloping logic as a formal theory of computability, as opposed to the formal theory of truth that logic has more traditionally been. Formulas in it represent computational problems, "truth" means existence of an algorithmic solution, and proofs encode such solutions. Within the line of research devoted to finding axiomatizations for ever more expressive fragments of CL, the present paper introduces a new deductive system CL12 and proves its soundness and completeness with (...) respect to the semantics of CL. Conservatively extending classical predicate calculus and offering considerable additional expressive and deductive power, CL12 presents a reasonable, computationally meaningful, constructive alternative to classical logic as a basis for applied theories. To obtain a model example of such theories, this paper rebuilds the traditional, classical-logic-based Peano arithmetic into a computability-logic-based counterpart. Among the purposes of the present contribution is to provide a starting point for what, as the author wishes to hope, might become a new line of research with a potential of interesting findings—an exploration of the presumably quite unusual metatheory of CL-based arithmetic and other CL-based applied systems.

Empiricism had dominated scientific activities for about three centuries but beginning with the 20th Century a new philosophy, phenomenology, began to develop and certain scientists who conducted research with humans began to turn to phenomenology as the basis for their scientific work rather than empiricism. What was known as the Utrecht School in Holland just after World War II, psychologists at Duquesne University during mid-twentieth century, pedagogists in Canada at about the same time and nurses later in the twentieth century (...) all began to base their research on phenomenological philosophical principles rather than on empiricism. Certain philosophers criticized the approach of these scientists and offered their own praxis based directly on phenomenological philosophy. However, one of the members of the Duquesne University’s group strongly criticized the evaluation of his approach by the philosophers and demonstrated the significant errors of their criticism. The psychologist then clarified his scientific phenomenological approach toward psychological phenomena and emphasized the role of the phenomenological epoche’ and reduction for Husserlian scientific phenomenology.

Phenomenology is a philosophy and it will always remain one. However, philosophies are also foundations for sciences and thus far in the West some form of empiricism or other has been the primary foundation for all sciences. Phenomenological philosophy has been developing for about a century now and is mature enough to serve as a basis for a science, especially the human sciences. This article articulates how phenomenological philosophy can serve as a foundation for the science of phenomenological psychology and (...) it indicates how its key concepts are better able to clarify and develop a proper understanding of human reality in a rigorous scientific way.

This paper presents a soundness and completeness proof for propositional intuitionistic calculus with respect to the semantics of computability logic. The latter interprets formulas as interactive computational problems, formalized as games between a machine and its environment. Intuitionistic implication is understood as algorithmic reduction in the weakest possible — and hence most natural — sense, disjunction and conjunction as deterministic-choice combinations of problems , and “absurd” as a computational problem of universal strength.

Within the program of finding axiomatizations for various parts of computability logic, it was proven earlier that the logic of interactive Turing reduction is exactly the implicative fragment of Heyting’s intuitionistic calculus. That sort of reduction permits unlimited reusage of the computational resource represented by the antecedent. An at least equally basic and natural sort of algorithmic reduction, however, is the one that does not allow such reusage. The present article shows that turning the logic of the first sort of (...) reduction into the logic of the second sort of reduction takes nothing more than just deleting the contraction rule from its Gentzen-style axiomatization. The first sort of interactive reduction is also shown to come in three natural versions. While those three versions are very different from each other, their logical behaviors turn out to be indistinguishable, with that common behavior being precisely captured by implicative intuitionistic logic. Among the other contributions of the present article is an informal introduction of a series of new — finite and bounded — versions of recurrence operations and the associated reduction operations.

David Katz was an experimental psychologist who worked in the early years of psychology as an independent science. He performed many experiments on color vision and touch by means of what he called the “phenomenological method.” He claimed to have learned the method by attending Husserl’s lectures on phenomenological philosophy while the latter was teaching at Göttingen. However the method that Katz actually used was “description with an attitude of disciplined naiveté”. Consequently, while such a method was known as “phenomenological” (...) at the time Katz was working, the nomenclature reflects a historically dated meaning of phenomenology and not the sense of phenomenological method that Husserl developed later in his career. Katz’s method was actually qualitative and empirical. It was not phenomenological according to Husserl’s complete, mature philosophy. (shrink)

It is often asserted that a liberal theory of political obligation is unattainable. This is, largely, because liberalism revolves around consent and hence, is supposed to be intrinsically inimical to the existence of state authority. However, there is at least one liberal proposal – the argument of fair play, that makes a plausible case for justifying the establishment of a coercive entity. The most popular contemporary version of it, which is offered by George Klosko, turns on the fact that non-excludable (...) goods cannot be exchanged based on consent. Instead, there must be enforceable, independent, objective standards of fairness that should govern the distribution of the effects of such goods. In this article, I argue that if Klosko’s account is correct, then not only the existence of non-excludable goods but also, the production and exchange of existentially significant excludable goods warrant an establishment of coercive authority. I argue that in this way, we can take an important step towards establishing a full-blown liberal theory of political obligation. (shrink)

Historically, when psychology broke away from a philosophical mode of scholarship it strove to become a natural science. This meant that it largely imitated the concepts and practices of the natural sciences which included the use of abstract terms to designate many of its phenomena with the consequence that psychology is often more abstract and generic than it ought to be. Husserl has emphasized the role of the life-world as the ultimate basis of all knowledge and a serious consideration of (...) its role implies that psychology’s manner of labeling its phenomena should be less abstract and closer to the way the phenomena are experienced in the lifeworld. If so, this means that psychology’s primary data should be physiognomies or the expressive characteristics intrinsic to objects and situations. However, the complexities involved in the perception of physiognomies create difficulties for the practice of science. It is suggested that certain Husserlian phenomenological contributions concerning categorial modes of experiencing could be helpful in meeting scientific criteria. (shrink)

I present a semantics for the language of first-order additive-multiplicative linear logic, i.e. the language of classical first-order logic with two sorts of disjunction and conjunction. The semantics allows us to capture intuitions often associated with linear logic or constructivism such as sentences = games, SENTENCES = resources or sentences = problems, where “truth” means existence of an effective winning strategy.The paper introduces a decidable first-order logic ET in the above language and gives a proof of its soundness and completeness (...) with respect to this semantics. Allowing noneffective strategies in the latter is shown to lead to classical logic.The semantics presented here is very similar to Blass's game semantics. Although there is no straightforward reduction between the two corresponding notions of validity, my completeness proof can likely be adapted to the logic induced by Blass's semantics to show its decidability, which was the main problem left open in Blass's paper.The reader needs to be familiar with classical logic and arithmetic.

In an earlier article, Edwards tried to establish that the Duquesne Phenomenological Research Method was simply a particular type of Case Study research method and he also reproached users of the DPRM for not developing theory. This article rebuts both of Edwards's theses. DPRM is radically different from CSRM in logic and in execution and the article demonstrates that the development of theory is not at all the intent of DPRM. The basic difficulty is that Edwards attempts to understand DPRM (...) from an empirical philosophical perspective whereas a phenomenological philosophical perspective is required to understand DPRM correctly.

The majority of G protein-coupled receptors (GPCRs) self-assemble in the form dimeric/oligomeric complexes along the plasma membrane. Due to the molecular interactions they participate, GPCRs can potentially provide the framework for discriminating a wide variety of intercellular signals, as based on some kind of combinatorial receptor codes. GPCRs can in fact transduce signals from the external milieu by modifying the activity of such intracellular proteins as adenylyl cyclases, phospholipases and ion channels via interactions with specific G-proteins. However, in spite of (...) the number of cell functions they can actually control, both GPCRs and their associated signal transduction pathways are extremely well conserved, for only a few alleles with null or minor functional alterations have so far been found. This would seem to suggest that, beside a mechanism for DNA repairing, there must be another level of quality control that may help maintaining GPCRs rather stable throughout evolution. We propose here receptor oligomerization to be a basic molecular mechanism controlling GPCRs redundancy in many different cell types, and the plasma membrane as the first hierarchical cell structure at which selective categorical sensing may occur. Categorical sensing can be seen as the cellular capacity for identifying and ordering complex patterns of mixed signals out of a contextual matrix, i.e., the recognition of meaningful patterns out of ubiquitous signals. In this context, redundancy and degeneracy may appear as the required feature to integrate the cell system into functional units of progressively higher hierarchical levels. (shrink)

Hájek and Montagna proved that the modal propositional logic ILM is the logic of -conservativity over sound theories containing I (PA with induction restricted to formulas). I give a simpler proof of the same fact.

Dzhaparidze, G., A generalized notion of weak interpretability and the corresponding modal logic, Annals of Pure and Applied Logic 61 113-160. A tree Tr of theories T1,...,Tn is called tolerant, if there are consistent extensions T+1,...,T+n of T1,...,Tn, where each T+i interprets its successors in the tree Tr. We consider a propositional language with the following modal formation rule: if Tr is a tree of formulas, then Tr is a formula, and axiomatically define in this language the decidable logics TLR (...) and TLRω. It is proved that TLR yields exactly the schemata of PA-provable sentences, if Tr is understood as “Tr is tolerant”. In fact, TLR axiomatizes a considerable fragment of provability logic with quantifiers over ∑1-sentences, and many relations that have been studied in the literature can be expressed in terms of tolerance. We introduce and study two more relations between theories: cointerpretability and cotolerance which are, in a sense, dual to interpretability and tolerance. Cointerpretability is a characterization of ∑1-conservativity for essentially reflexive theories in terms of translations. (shrink)

Any living organism interacts with and responds specifically to environmental molecules by expressing specific olfactory receptors. In this paper, this specificity will be first examined in causal terms with particular emphasis on the mechanisms controlling olfactory gene expression, cell-to-cell interactions and odor-decoding processes. However, this type of explanation does not entirely justify the role olfactory receptors have played during evolution, since they are also expressed ectopically in different organs and/or tissues. Homologous olfactory genes have in fact been found in such (...) diverse cells and/or organs as spermatozoa, testis and kidney where they are assumed to act as chemotactic sensors or renin modulators. To justify their functional diversity, homologous olfactory receptors are assumed to share the same basic role: that of conferring a self-identity to cells or tissues under varying environmental conditions. By adopting this standpoint, the functional attribution as olfactory or chemotactic sensors to these receptors should not be seen either as a cause conditioning receptor gene expression, or as a final effect resulting from genetically predetermined programs, but as a direct consequence of the environmental conditions olfactory receptor genes have explored during evolution. The association of odorant patterns with specific environmental or contextual situations makes their relationship semiotically triadic, due to the emergence of an interpretant capable of perceiving odorants as meaningful signs out of a noisy background. This perspective highlights the importance of odorant-receptor relationships as respect to the properties of the interacting partners. It is our contention that only when taken together can these different explanatory strategies provide a realistic account of how olfactory receptor genes have been structurally and functionally modified during evolution.

It seems that many qualitative researchers have still not contextualized the role of validity in qualitative analysis.This article enumerates three factors that must be taken into account: The philosophy of science within which one works, the discipline to which one belongs, and the subfield of specialization that one pursues. Most researchers have encountered the question of validity within the context of empirical science, but validity does not have the same role within a phenomenological philosophy of science. Within the discipline of (...) psychology, certain subfields ignore the validity issue for good reasons and other subfields specialize in developing strategies for validity. This article analyzes the reasons that the specialty of "test construction" focuses so strongly on validity issues and concludes that phenomenological qualitative research is not at all similar to the situation one finds in test construction. Rather, phenomenological qualitative research is closer to experimental situations and so the validity issue is not as pressing as is often supposed. The article ends with two different Husserlian perspectives on a theory of knowledge. (shrink)

Scholars describe Global North feminisms as mostly ‘secular’ and often opposing religion. Contemporary feminist intersectional movements seem to offer different approaches able to overcome distances and articulate the role of religion in feminist emancipatory practice.

The results highlight that religious women are increasingly part of feminist intersectional movements. Nonetheless, religious inequalities are often overlooked, and religion triggers ambivalent (...) reactions, often resulting in a process of othering minority women. (shrink)

Cell communication plays a key role in multicellular organisms. In developing embryos as in adult organisms, cells communicate by coordinating their differentiation through the establishment and/or renewal of a variety of cell communication channels. Under both these conditions, cells interact by either receptor signalling, surface recognition of specific cell adhesion molecules or transfer of cytoplasmic components through junctional coupling. In recent years, it has become apparent that cells may also communicate through the extracellular release of microvesicles. They may originate as (...) either exosomes from the endosomal compartment upon fusion of multivesicular bodies with the plasma membrane or be shed directly from the plasma membrane via extensions of the cell surface. Microvesicles may disperse over long distances through body fluids and deliver their molecular cargo onto a variety of target cells. As a general rule, the metabolic fate of these cells is determined by the molecular nature of the vesicular cargo, while targeting itself depends on the affinity of the molecules expressed on the enclosing membrane. In this paper, we will be arguing that intercellular vesicular transfer is substantially different from other types of cell communication, allowing cells and molecules to interact on varying levels. Cells interacting via ligand signalling owe their specificity to the steric coupling with cognate receptor molecules. As such, it is a pure molecular process that affects target cells only upon integration into their responding repertoire. In this relationship, coupled cells are reciprocally adapted to each other through the selection of their respective signalling capacities, following exploration of their receptor specificity. Interaction by intercellular vesicles realizes a substantially different type of cell communication. Vesicular traffic allows donor cells to carry out a horizontal type of gene transfer and target this information over long distances via independently controlled mechanisms. Because of this independence, cells interacting via vesicular traffic are not expected to adapt their signalling correspondences, but to control instead the efficiency of their cargo delivery irrespective of the receptor repertoire expressed by the target tissue. In this paper, the multifaceted functions of the intercellular vesicular traffic will be discussed in a multilevel biosemiotic perspective with the aim of unravelling the cellular mechanisms devised by nature to accomplish communication.
