Metaepistemology may be partly characterized as the study of the nature, aims, methods and legitimacy of epistemology. Given such a characterization, most epistemological views and theories have an important metaepistemological aspect or, at least, a number of more or less explicit metaepistemological commitments. Metaepistemology is an important area of philosophy because it exemplifies that philosophy must serve as its own metadiscipline by continuously reflecting critically on its own methods and aims. Even though philosophical methodology may be regarded as a branch of epistemology, epistemology itself is as much in need of metaphilosophical examination as other core disciplines of philosophy. Moreover, metaepistemology is important because it bears significantly on first-order epistemological questions. Indeed, many of the most prominent contemporary debates in philosophy have a distinctly metaepistemological aspect. For example, the debates between rationalists and empiricists do not only concern the nature of cognition of specific areas – perception, arithmetic, logic and so forth – but also general metaepistemological questions about whether it is realistic and desirable that epistemology be naturalized. Likewise, the debates between epistemic internalists and externalists include metaepistemological debates about whether the proper focus for epistemology should be the cognizer’s rational perspective or some more objective property of the cognizer’s epistemic position. Similarly, the debates concerning the relationship between folk epistemology and epistemological theorizing include metaepistemological debates about how empirical data concerning folk epistemology should impact epistemology itself. Each of these debates provides an example of how first-order epistemological issues are deeply connected, and sometimes inseparable from, metaepistemological considerations.

Abstract:The relationship between chromatically modulated stimuli and visual evoked potentials (VEPs) was considered. VEPs of normal subjects elicited by chromatically modulated stimuli were measured under several color adaptations, and their binary kernels were estimated. Up to the second-order, binary kernels obtained from VEPs were so characteristic that the VEP-chromatic modulation system showed second-order nonlinearity. First-order binary kernels depended on the color of the stimulus and adaptation, whereas second-order kernels showed almost no difference. This result indicates that the waveforms of first-order binary kernels reflect perceived color (hue). This supports the suggestion that kernels of VEPs include color responses, and could be used as a probe with which to examine the color visual system.

AbstractThe relationship between a firm and its supply chain has been well studied, however, the association between the position of firms in complex supply chain networks and their performance has not been adequately investigated. This is primarily due to insufficient availability of empirical data on large-scale networks. To addresses this gap in the literature, we investigate the relationship between embeddedness patterns of individual firms in a supply network and their performance using empirical data from the automotive industry. In this study, we devise three measures that characterize the embeddedness of individual firms in a supply network. These are namely: centrality, tier position, and triads. Our findings caution us that centrality impacts individual performance through a diminishing returns relationship. The second measure, tier position, allows us to investigate the concept of tiers in supply networks because we find that as networks emerge, the boundaries between tiers become unclear. Performance of suppliers degrade as they move away from the focal firm (i.e., Toyota). The final measure, triads, investigates the effect of buying and selling to firms that supply the same customer, portraying the level of competition and cooperation in a supplier’s network. We find that increased coopetition (i.e., cooperative competition) is a performance enhancer, however, excessive complexity resulting from being involved in both upstream and downstream coopetition results in diminishing performance. These original insights help understand the drivers of firm performance from a network perspective and provide a basis for further research.

Abstract This paper studies the relationship between labelled and nested calculi for propositional intuitionistic logic, first-order intuitionistic logic with non-constant domains and first-order intuitionistic logic with constant domains. It is shown that Fitting’s nested calculi naturally arise from their corresponding labelled calculi—for each of the aforementioned logics—via the elimination of structural rules in labelled derivations. The translational correspondence between the two types of systems is leveraged to show that the nested calculi inherit proof-theoretic properties from their associated labelled calculi, such as completeness, invertibility of rules and cut admissibility. Since labelled calculi are easily obtained via a logic’s semantics, the method presented in this paper can be seen as one whereby refined versions of labelled calculi (containing nested calculi as fragments) with favourable properties are derived directly from a logic’s semantics.

In this paper the relationship between dependency theory and first-order logic is explored in order to show how relational chase procedures (i.e., algorithms to decide inference problems for dependencies) can be interpreted as clever implementations of well known refutation procedures of first-order logic with resolution and paramodulation. On the one hand this alternative interpretation provides a deeper insight into the theoretical foundations of chase procedures, whereas on the other hand it makes available an already well established theory with a great amount of known results and techniques to be used for further investigations of the inference problem for dependencies. Our presentation is a detailed and careful elaboration of an idea formerly outlined by Grant and Jacobs which up to now seems to be disregarded by the database community although it definitely deserves more attention.

AbstractThis article discusses the relationship between certain institutional regulations of voting rights and elections, different levels of electoral participation, and the degree of political instability in several Latin American political experiences. A formal model specifies the hypotheses that sudden enlargements of the electorate may provoke high levels of political instability, especially under plurality and other restrictive electoral rules, while gradual enlargements of the electorate may prevent much electoral and political innovation and help stability. Empirical data illustrate these hypotheses. A historical survey identifies different patterns of political instability and stability in different countries and periods, which can be compared with the adoption of different voting rights regulations and electoral rules either encouraging or depressing turnout.

AbstractWe use a new construction of an o-minimal structure, due to Lipshitz and Robinson, to answer a question of van den Dries regarding the relationship between arbitrary o-minimal expansions of real closed fields and structures over the real numbers. We write a first order sentence which is true in the Lipshitz-Robinson structure but fails in any possible interpretation over the field of real numbers.

Although the relationship between stressors and thriving at work has been established, the linkage between them is still in the early stages of theory development. This study proposed a two-path model, based on Lepine’s stressors-performance model, to analyze the effects of the stressors on the thriving at work. Two complementary mediating paths were proposed, i.e., affective strain (positive affect) and motivation (self-efficacy), which were explained using affective events theory and expectancy theory, respectively. Based on the empirical data from 233 employees, the results show that challenge stressors could enhance employees’ positive affect and self-efficacy, thus leading to thriving at work; on the contrary, hindrance stressors would result in negative influences. In addition, it is also found that the effect of affective path tend to be greater than that of motivation path, which could provide a practical guide for organizations to effectively apply stress management and to promote employees thriving at work.

Artikkelissa tarkastellaan suomalaisen murteentutkimuksen historiaa suomen kielen alalla ilmestyneiden murteita käsittelevien väitöskirjojen lähdeluetteloiden avulla. Artikkelissa käsitellään dialektologian ja sosiolingvistiikan suhdetta sekä perustellaan sitä, miksi alueellisen vaihtelun tutkimushistoriaa on tarpeen tarkastella kokonaisuutena. Aineistona on 41 väitöskirjan lähdeluetteloista koostettu lähdetietokanta, jota analysoidaan tekijä-, nimike- ja julkaisuvuositietojen näkökulmasta.  Lähdetietokannan viitatuin sadasosa tekijöistä kattaa 27 tutkijaa, joihin on viitattu lähdetietokannassa 40–316 kertaa. Yhteensä tähän tekijäjoukkoon viitataan lähdetietokanta-aineistossa 2 672 kertaa. Yli 10 kertaa lähdeluetteloissa mainittuja tekijöitä on 150. Miesten tekemään tutkimukseen viitataan useammin kuin naisten ja kotimaisten tutkijoiden tekemään tutkimukseen useammin kuin ei-kotimaisten. Murteita käsittelevissä väitöskirjoissa ei viitata juuri lainkaan tutkimukseen, joka olisi kotimaisten ja ei-kotimaisten tutkijoiden yhteistyössä tekemää. Sekä tekijöiden sukupuolen että kotimaisuuden näkökulmasta on havaittavissa paitsi laaja väitöskirjakohtainen vaihtelu myös tendenssi kohti kansainvälistymistä ja naisten tasavertaisempaa edustusta tutkimusalalla. Aineiston kumulatiivinen luonne aiheuttaa vanhojen nimikkeiden painottumisen. Tämä näkyy esimerkiksi siitä, että uusimmat pelkän frekvenssin perusteella viitatuimmiksi määritetyt teokset ovat ilmestyneet vuonna 1966. Tätä vinoutumista voi tasapainottaa tarkastelemalla viitattujen nimikkeiden julkaisuvuoteen suhteutettua suhdelukua. Myös siten, että tarkasteluun ottaa nimikkeet, joihin on viitattu neljäsosassa väitöskirjoja (88 kpl), on joukko vähemmän homogeeninen. Julkaisuvuosien ja nimikkeiden jakautumista verrattaessa voi perustellusti todeta, että 1900-luvun loppupuoliskolla ilmestyneisiin nimikkeisiin viittaaminen on heterogeenisempää kuin vuosisadan alkupuoliskolla ilmestyneisiin. Tätä selittävät paitsi tutkimuksen monimuotoistuminen myös sen määrän kasvu. Lähdeluetteloiden tarkasteleminen tuo uuden näkökulman tutkimushistorian analysointiin. Se todentaa empiirisesti, keihin ja mihin tutkimuksiin tieteenalalla viitataan. Kvantitatiivisen luonteensa vuoksi näkökulma tarjoaa myös paljon lisäkysymyksiä laadulliselle jatkotutkimukselle.   Dialect study in the light of citations This article considers research history on dialects in Finland. It examines the relationship of dialectology and sociolinguistics in the study of dialects and explains why they must be understood as one continuous research history. The data used in this article comes from a citation database compiled from the bibliographies of 41 doctoral theses. In the citation database, 27 researchers comprise the most cited 1%; they have been cited between 40 and 316 times. The most cited 1% has been cited in the database a total of 2,672 times, while 150 individual researchers have been cited over 10 times. Men are cited more often than women, and Finnish researchers have been cited more frequently than non-Finnish ones. There are almost no citations to research that has been conducted jointly by a Finnish and non-Finnish researcher. The variation in citing women and non-Finnish researchers is great, and there is a tendency towards more international and equal citing. The cumulative nature of the data means that older research is over-represented. This can be deduced from the fact that the newest frequently cited research dates from 1966. This distortion can be balanced by creating and analysing a ratio based on the year in which individual works were published. Also, when looking at the research that has been cited in a quarter of all dissertations (88), the data becomes less homogenous. When analysing the amount of research published, it is justified to say that citing in the late 20th century is more heterogeneous than it was at the beginning of the century. The diversification and increased volume of research explains this change.  The article demonstrates how a quantitative perspective, based on citations, can enhance our understanding of research history. It verifies with empirical data whom and which research has been cited over the years. Finally, the article concludes what kinds of questions concerning research history arise and can still be answered by further investigating the citation database.

In this work, the photocatalytic degradation of indigo carmine (IC) using zinc oxide suspension was studied. The effect of influential parameters such as initial indigo carmine concentration and catalyst loading were studied with the effect of Vis irradiation in the presence of reused ZnO was also investigated. The increased in initial dye concentration decreased the photodegradation and the increased catalyst loading increased the degradation percentage and the reused-ZnO exhibits lower photocatalytic activity than the ZnO catalyst. It has been found that the photocatalytic degradation of indigo carmine obeyed the pseudo-first-order kinetic reaction in presence of zinc oxide. This was found from plotting the relationship between ln (C0/Ct) and irradiation the rate constant of the process.UV- spectrophotometer was used to study the indigo carmine photodegradation.
