Technological Change and Its Effect on Education

This work follows the historical interplay between technological advancements and educational systems and highlights that strengthening education has been a key driving force behind the Second and Third Industrial Revolutions. It seems, however, that the arrival of the Fourth Industrial Revolution --- bringing communication platforms, AI and renewable energy --- caught educational institutions unprepared. Whether we like this or not, this technological shift means the educational landscape is bound to change. This article examines the evolving dynamics of modern education amidst a new wave of technological progress, highlighting the rise of student 'collectives' which result from a distinctive synergy among students, communication platforms, and generative AI technologies. The article expresses scepticism regarding the use of strategies that are becoming practically ineffective, technologically outdated and contradictory to prevalent student practices. It advocates for adopting educational principles appropriate for the modern era and capable of upholding academic integrity in the strictest sense. If modern technology seems incompatible with academic integrity when examined within some traditional educational practices, this can mean only one thing---these practices must change. A significant challenge lies in implementing these changes without overburdening already limited educational resources. The article proposes practical principles and measures to ensure that universities can still be a driving force behind technological progress and innovation while upholding and promoting the highest standards for their research and education.

The Principle of Explosion in the Stoic Logic

I argue that the Stoic logic is explosive. The claim applies to the Stoics' syllogistic in the strictest sense, because there is a provable syllogism which qualifies as a principle of explosion. It applies also to the general consequence operation, in the sense that every sentence is derivable from any pair containing both a sentence and the negation of the sentence. Finally, it applies to the connective of implication (conditional), in the sense that any conditional is derivable, providing its antecedent is a conjunction of a sentence and the negation of the sentence. All three claims allow weakening, i.e., additions of extra premises to an inference or extra conjuncts to the antecedent of an implication, respectively. Consequently, no concept of relevance, let alone paraconsistency or connexivity is applicable to the Stoic logic; in particular, the Stoics' connective of implication is either material (Boolean) or formal (strict).

Neurotechnologies, Ethics, and the Limits of Free Will.

This article delves into the implications of neurotechnologies for the philosophical debates surrounding free will and moral responsibility. Tracing the concept from ancient religious and philosophical roots, we discuss how recent neurotechnological advancements (e.g. optogenetics, fMRI and machine learning, predictive diagnostics, et al.) challenge traditional notions of autonomy. Although neurotechnologies aim to enhance autonomy in the strict sense - as self-determination - they risk reducing or changing the broader notion of autonomy, which involves personal authenticity. We also submit that, in a world with an altered or limited concept of free will, humans should still be held accountable for actions executed through their bodies. By examining the dynamic between choice and responsibility, we emphasize the shift in technology ethics, moral philosophy, and the broader legal landscape in response to the advancement of neurotechnologies. By bringing the neurotechnological innovations into the world, neuroscientists not only change the technological landscape but also partake in long-standing moral narratives about freedom, justice, and responsibility.

Body, scar, memory and identity: theological reflections from the other side

This text is set out from the autobiographical narratives of the author that from the view of the cultural studies and the meeting with the Bible, invites us to read our body from the unconventional categories, challenging us to make theology from the other side. The interpretation of the Bible from women and blackness, on the other hand, is related to the way the author understands her life story, that is why methodologically she start with a biblical text that has to do with the proposed categories, immediately she goes from the story to life and then to an analytical reflection of the chosen category to finally present a theological illumination of that situation. It is not an exegesis in the strict sense of the word, the text is just a pretext to allow us to read life from the other side, that is, from the margins of officially.

On Traces, Clues, and Fiction: Carlo Ginzburg and the Practice of Archaeology

Abstract In recent years, archaeological research has relied on large datasets, both temporally and geographically, with some archaeologists discussing that there should be a shift towards a more scientific form of conducting archaeological research called “macroarchaeology.” Ironically, and contradictorily, this shift towards large-scale research has involved the use of inductive approaches, which means that archaeological material needs to be converted into universal quantitative values. The inductive approaches used by archaeologists today, as argued by Karl Popper, and other authors in recent years, cannot be considered scientific in the strict sense of the word, since there is always a degree of uncertainty in inductive reasoning. This study suggests that archaeological data can be considered as traces of the past, clues that allow us to reconstruct past phenomena. As Carlo Ginzburg’s evidential paradigm demonstrates, thinking of the past in terms of traces and clues is much more scientific than appears at first. In addition to traces and clues, a second interpretative procedure can be conducted on data. Based on Ginzburg’s conjectural paradigm and discussion on fiction, we can recognize the past as real, while at the same time, conjecture the several ways past agents could have acted otherwise.

Three-dimensional property: Current development trends on the Polish example

Abstract 126The majority of modern European legislations traditionally follows the concept of land ownership derived from Roman law. It is based on the assumption that the owner’s rights are unlimited in spatial terms. Within this understanding, the spatial scope of ownership extends to open space above and below a specific part of the land’s surface, delineated two-dimensionally. Several exceptions to the general underlying approach have been successively introduced in particular European legal systems in the course of historical development. These include, in the first place, building leases and apartment ownership as well as separate ownership of buildings. Furthermore, widely accepted limitations as to the vertical scope of ownership stem from specific regulations in the fields of mining law, geological law, water law and aviation law. Another manifestation of departure from the traditional concept of land ownership are legal solutions falling into the category of three-dimensional (3D) property, which is of increasing interest nowadays in view of growing needs for new forms of ownership and land use in densely built urban areas. At the core of the concept of 3D property in the strict sense lies the possibility to divide the space into distinct layers defined by horizontal and vertical planes, and to create so-called three-dimensional immovable properties which constitute independent objects of property rights. Such 3D units can serve multiple above- and underground investment purposes. Regulations regarding different models of 3D property rights have already been adopted in a number of countries in Europe and worldwide. Recently, conceptual work on layered ownership has been undertaken in Poland, which has opened a discussion in the legal scholarship on the future legislative changes to be implemented in order to introduce the notion of 3D property to domestic law. In parallel with these tendencies, the idea of 3D cadastre is being promoted. It offers 127the possibility to register real estate objects located at different levels. Worthy of note in this regard is also the impact of the current technological advancements on increasing the investment potential of urban space through 3D property formation. This article elaborates, first, on the general concept and selected types of 3D property rights existing in national jurisdictions. Against this background, the proposal for the new legal construct of layered ownership has been discussed with particular consideration of the possible ways of adapting it to the Polish property law framework. Some of the opportunities and challenges brought about by the 3D property rights development have been then outlined in the context of extensive implementation of emerging technologies in real estate transactions.

Notes on australasian orchids 8: Eight new species of <i>Hymenochilus</i> (Cranichideae: Pterostylidinae) and clarification of two previously described species

Eight new species of Hymenochilus from Australia are described and illustrated. Six of the new species have affinities to (and are here compared with) H. cycnocephalus: H. anemophilus, H. calcicola, H. cymbellus, H. longipes, H. nemoralis and H. pachylus. Hymenochilus anemophilus is shorter (2–8 cm), with dark green strongly veined rosette leaves, crowded dark green flowers, oblong to obovate labellum lamina and, a broader blunter beak on the labellum appendage; H. calcicola is shorter (3–12 cm), crowded green flowers with prominent dark green stripes, ovate petals with a strongly developed basal flange on the anterior side and narrow elliptic labellum lamina with a broad pointed beak on the labellum appendage; H. cymbellus differs by its sparser basal rosette with narrower rosette leaves, thinner scapes, flowers with distinct darker green stripes and shallowly saccate lateral sepals that narrow inwards to a distinctly pointed apex; H. longipes differs by its thin-textured rosette leaves, widely spaced darker green flowers with darker green veins, elliptic-obovate labellum lamina and a longer labellum basal appendage which protrudes prominently from the flower in side view; H. nemoralis has longer rosette leaves, thicker scape and darker green flowers with prominent narrow dark green stripes; H. pachylus has thicker rosette leaves, taller, thicker scape, flowers prominently striped, elliptic-obovate labellum lamina and labellum appendage with a short thick beak. Two of the new species have affinities (and are here compared) with H. muticus: H. pagophilus and H. pisinnus. Hymenochilus pagophilus differs by its moderately crowded to crowded flowers, broader, shinier flowers and rectangular-obovate labellum and H. pisinnus differs by its smaller rosette with smaller, narrower leaves, thinner scape, smaller flowers, that are often on long pedicels, shorter, shallowly saccate lateral sepals, smaller rhomboid petals and, smaller obovate labellum. In addition, Hymenochilus cycnocephalus and H. muticus, are characterised in the strict sense with full descriptions, distribution, and habitat.

GREGORIUS AS A TRANSLATOR AND AN INTERPRETER OF LIFE

Gregorius, as translator of The Goldsmith of Words and detective "interrogating the survivors," assumes the role of translating a vast complex of philosophical questions as well as dramatic historical events and their impact on the fate of the individual and the collective. In his second novel, Mercier, by the means of his character of the intellectual translator, treats the process of translation as a process of mediating knowledge; his hero/antihero Gregorius is not a translator in the strict sense of the word; translation is modelled in the text as a means of learning a foreign language and, consequently, as a linguistic ability that allows the mediation of knowledge from a foreign language. However, he is deeply rooted in the text and the language, therefore the typology of the figure of the translator as developed by Klaus Kaindl (2010) can be applied to Gregorius when he distinguishes between physical, psychological and cognitive dimensions. Gregorius fulfils the image of physical deficiencies (eyesight), weaknesses or illnesses (Gregorius loses consciousness and, at the end of the novel, goes to the hospital for a thorough examination, which he expects to rule out the presence of a tumour). He also fulfils Kaindl's characteristics of the psychological dimension, as he displays hesitation, anxiety, fear of new contacts and of the new in general, etc. It is only in the cognitive dimension that he is one of those representatives who does not show burnout in the form of mechanical work - or perhaps we trace a certain mechanisation in his practice as a teacher (everything happens the same way every day), but it is the translation of the new book that brings him out of this stagnation and leads him to the Lisbon adventure. This is also why, as we stated, we understand the function of translation in the novel in relation to classical languages as both escape and knowledge, but as far as Portuguese is concerned, we consider the translation from it as a cathartic element through which Gregorius narrates what he could not narrate himself. At the same time, it can be said that Pascal Mercier creates a different type of translator than most contemporary prose with this type of character, especially migrant prose. The author also makes purposeful use of the genre of the psychological and philosophical novel, and through hypertextuality and the novel within the novel, he creates a wide space for his reflections, especially on the philosophy of language, freedom of will and the you/interpretation of identity. The protagonist is a translator in relation to Prado's book The Goldsmith of Words, and an interpreter of Prado's thoughts in relation to his story, while an intradiegetic autodiegetic narrator (Prado) is involved in The Goldsmith of Words, the plot of The Night Train to Lisbon is narrated by an extradiegetic heterodiegetic narrator, but at the same time Gregorius as a character in relation to the fictional hypothetical The Goldsmith of Words becomes an intradiegetic heterodiegetic narrator, but technically realized through semi-direct speech. While in the translator position Mercier strives to express his desire for perfection in translation, for an accurate and faithful transfer of meaning from one language to another, just as Gregorius does not only with Portuguese but also with the classical languages, in the interpreter position he moves away from the common perception of interpreting as a reproduction of content and becomes an interpreter of interpretation, as he seeks to imbue the translated content with meaning or confronts it with his own knowledge. As if translation and reinterpretation were not enough, Mercier uses the protagonist to explore what these two acts of working with language can do to a person and how they imprint themselves in self-knowledge.

A mondhatóság határai

Romantic poetry can be described with the conflicting terms of tradition and originality: its essence is not originality in the strict sense, but rather the deformation of tradition. The sovereignty of the Romantic poet does not come from the negation of tradition, but from acquiring and using it consciously. The paper discusses two poems of Petőfi which anticipate the unity of experience and representation, but they both end with arguing for the impossibility of such union. In What Shall I Call You? metaphorical expression becomes a questionable method, while in A Time of Fear narrative sense-making connected to temporal experiences turns out to be impossible. Both poems face the limits of expression, although in different ways: What Shall I Call You? deals with the impossibility of verbalising individual experiences, while A Time of Fear comes to the same conclusion regarding collective experiences. The two poems demonstrate it well how Petőfi initiated a phenomenon representative of the late Romantic period.

Traceable frequency measurements with counters

Received signals from Global Navigation Satellite Systems (GNSS) are nowadays widely used by industry laboratories for ensuring metrological traceability for their respective range of calibration services in the field of time and frequency. Usually, a local frequency standard is steered by continuous GNSS signal reception providing at its output stable and accurate reference signals for the laboratory measurement equipment, in general for synthesizers and counters. Reception of GNSS signals is surely an adequate and practical tool for the purpose, however further steps are needed to establish traceability in a strict metrological sense. Based on already available guidelines and publications, this paper is a contribution to the discussion how metrological traceability to internationally accepted standards can be established in a calibration laboratory. We restrict the discussion to equipment in common use which may not necessarily be of the highest sophistication. In this spirit, we develop a detailed scheme for an uncertainty budget comprising all links of the traceability chain from the device under test to the SI second, the scale-unit of Coordinated Universal Time. Then we go through and apply this scheme step by step to a demonstration setup for frequency measurements with a counter with varying operational parameters. In this framework, a novel approach to distinguish between components of statistical measurement uncertainty is introduced. Furthermore, the limiting uncertainty contributions are discussed and based on a suitable set of parameters an expression for the best measurement capability is given. With this scheme at hand a user may develop an uncertainty budget adapted to his own setup, especially if acceptance from a national accreditation body is sought.

Non-Symmetry in the Shock Refraction at a Closed Interface as a Recovery Mechanism

The possibility of a shock wave recovery at a discrete closed interface with a heated gas has been investigated. A two-dimensional model applied to conditions of optical discharges featuring spherical, elliptical, and drop-like configurations demonstrated that non-symmetry in the shock refraction contributes to the specific mechanism of recovery other than simply its compensation. Even though the full restoration of the hypersonic flow state does not occur in a strict sense of it, clear reverse changes toward the initial shape of the shock front eventually take place, thus creating an appearance of a full recovery seen in experiments. From analysis of different interface symmetries, the factors determining the recovery dynamics are identified. The results are directly applicable to the problem of energy deposition into a hypersonic flow; however, it can be useful anywhere else where the flow modifications following the interaction are important. The dimensionless form of the equations allows applications on any scale other than that demonstrated for the optical discharges.

Four new species of Parvoplaca (Teloschistales, Ascomycota)

The genus Parvoplaca is extended with four new species: P. candanii from Antarctica, P. lamprocarpa from Alaska, and P. macroborealis and P. tenebrosa from Oregon. Collections identified as P. tiroliensis are shown to form two independent clades when DNA was analyzed, but it is currently not clear which clade represents the species in a strict sense. Parvoplaca athallina has been considered an Antarctic species, but according to our analyses, the species is shown to be bipolar occurring also in northern Europe, Greenland, Alaska and in California.

Триба Potentilleae (за исключением Alchemilla; Rosaceae) во флоре Республики Дагестан: конспект, распространение, ключ для определения

A review of the tribe Potentilleae Sweet (except for Alchemilla L.) in the flora of the Republic of Dagestan with an identification key is presented. According to preliminary data, the tribe includes 8 genera and 36 species. Genus Potentilla L. is the most numerous and numbers 26 species. Among them, P. assalemica Soják is a new species for Russia, P. pedata Willd. ex Hornem. is reported for Dagestan for the first time, P. daghestanica Soják is a subendemic of the study region, which was omitted from the earlier published «Conspectus of the flora of Dagestan» (CFD). In the flora of Dagestan, the genera Fragaria L. and Sibbaldia L. consist of 3 and 2 species respectively; Aphanes L., Argentina Hill, Dasiphora Raf., Drymocallis Fourr. ex Rydb. and Sibbaldianthe Juz. include one species each. For some botanical-geographical regions of Dagestan new findings are given, including Potentilla adenophylla Boiss. and P. ruprechtii Boiss., subendemics of the Caucasus. Compared with CFD, Potentilla is considered here in a strict sense, with separation of such genera as Argentina, Dasiphora, Drymocallis, and Sibbaldianthe.

The nature of expression of avian immunity genes during infection with GALLID ALPHAHERPESVIRUS 2 and MELEAGRID ALPHAHERPESVIRUS 1

Marek's disease is a dangerous immunosuppressive viral disease of poultry. Most egg poultry farm in the Russian Federation vaccinate their chickens on the first day of life against this viral disease. Thanks to this vaccine prevention tactic, poultry farms protect themselves from the outbreak of this disease and economic damage. Traditionally, among the viruses related to this disease, there are the 1st serotype of the Marek's disease virus (Gallid alphaherpesvirus 2) and the 3rd serotype of the Marek's disease virus, which is not such in a strict taxonomic sense (Meleagrid alphaherpesvirus 1, also called turkey herpesvirus). When poultry is infected, this virus causes a significant change in the expression of the main immunity genes (IL6, PTGS2, IRF7). Based on the results obtained, it was concluded that the expression of the IL6 and PTGS2 genes was slightly higher than the level of expression of these genes in the control group. It is possible that local immunity was suppressed by the immunosuppressive properties of the Marek's disease virus. When studying the expression of the IRF7 gene, a strong effect of viruses of both serotypes on this gene was found, and Gallid alphaherpesvirus 2 exceeded the level of this effect compared to the effect of Meleagrid alphaherpesvirus 1 by 4 times. These results may indicate that sharply increasing expression of the IRF7 gene may be a sign of Marek's disease virus replication (since Gallid alphaherpesvirus 2 and Meleagrid alphaherpesvirus 1 interact with the same cellular receptor, the vaccine effect of Meleagrid alphaherpesvirus 1 is based on this). On the other hand, we can conclude that the introduction of these viruses does not cause inflammatory and immune reactions in the ileocecal tonsils of birds.

Mojżesz i srebrne trąbki Izraelitów (Lb 10, 1-10)

In this article a fragment from the Book of Numbers - Numbers 10:1-10, in which Moses is ordered to make two silver trumpets [חֲצֹצְרָה], has been shown in the research perspective, taking into account, above all, the biblical and historical contexts, as well as archaeo-musicological one. Contrary to the mythologized stories about inventors/ first builders of musical instruments from various areas of the Mediterranean Sea, this fragment contains an original account of the origin of the aerophone (Numbers 10:1-2). Due to their limited melodic capabilities, the ḥǎṣōṣěrâ trumpets, like their Egyptian šnb prototypes, were not musical instruments in the strict sense. They were usually used by priests descended from Aaron and the Levites. Numbers 10:2-10 includes historically reliable technological data (Numbers 10:2) and a developed usage profile of the aerophone (Lb 10:2-10), which is largely reflected in the referenced comparative material from the Old Testament (warfare, sacral celebrations in Jerusalem).

The Presumption of the Employment Relationship of Platform Workers as an Opportunity to Eliminate Obstacles Arising from Competition Law in the Conclusion of a Collective Agreement: The Example of Spain

Abstract Collective bargaining is the most appropriate tool to introduce detailed regulations specific to platform work. However, the status of platform workers (they are usually self-employed), combined with EU competition law, constitutes a significant restriction on their collective bargaining rights. Hence, the aim of this article is to prove the thesis that the presumption adopted in the Spanish regulation of recognising platform workers as workers in the strict sense would be a universal solution to the problem of ensuring proper labour protection for this group of workers.

Pragmatic Ambiguity, Implicatures, and Translation1

AbstractThe goal of this work is to put forward a pragmatic and translational framework for analysing target texts (TT) and source texts (ST) containing conversational implicatures that lead to pragmatic ambiguity. Ambiguity, sensu lato, is deemed to be related to indeterminacy and vagueness. Nevertheless, in the strict sense, ambiguity is understood as ‘more than a single processing instruction for a given utterance’. More specifically, pragmatic ambiguity arises whenever differences in cultural conventions between SL speakers and TL speakers lead to differences in the existence, meaning and salience of implicatures among ST and TT. Using real translation cases selected from a purpose‐built corpus containing fiction written and oral texts, we show which pragmatic ambiguities translators come across, and how translation techniques are used, either to maintain ambiguity or to select one intended processing instruction.

Molecular phylogeny of the fungus gnat subfamilies Sciophilinae and Leiinae (Mycetophilidae), with notes on Sciaroidea incertae sedis (Diptera: Bibionomorpha)

Abstract The phylogeny of the subfamilies Sciophilinae and Leiinae (Diptera: Mycetophilidae) is reconstructed, based on three nuclear (18S, 28S, CAD) and three mitochondrial (16S, COI, Cytb) gene fragments. The analysis supports the monophyly of Sciophilinae in a strict sense, without the Paratinia Mik, 1874 genus group and genera Aneura Marshall, 1896 and Taxicnemis Tonnoir and Edwards, 1927, the latter two revealed as being the most plesiomorphic within Mycetophilidae. The subfamily Leiinae is found monophyletic, but only in much narrower sense than it was defined based on recent morphological analyses. The genus TaiwanosciaroidesSaigusa, 2018 synon. nov. is considered to be a junior synonym of DeimyiaKallweit, 2002. A new molecular phylogeny of Sciaroidea is presented, based on longer sequences of nuclear genes (18S, 28S, CAD) and three mitochondrial gene fragments (12S, 16S, COI), including 10 genera of the Sciaroidea incertae sedis group. Eight of them grouped together (ufboot2 = 93), including RangomaramaJaschhof and Didham, 2002 (family Rangomaramidae). Two outlier genera, Ohakunea Edwards, 1927 and HeterotrichaChandler, 2002, grouped within Sciophilinae and as the sister-taxon to Sciaridae, respectively. Our results spark a debate over how to interpret and combine molecular and morphological data, and we refrain from reclassifications at this point.

Genomic selection in Eucalyptus globulus as an assisted selection tool for growth rate and disease resistance

The adoption of genomic selection (GS) in forest tree breeding allows shortening breeding cycles, increasing selection intensity, and improving the accuracy of breeding values, which translate into increased genetic gains. Therefore, the objective of this work was to design a breeding strategy incorporating GS in the Eucalyptus globulus improvement plan of the INIA. Using the single step genomic selection (ssGBLUP) methodology, a multi-trait model of GS was developed considering different ages of evaluation (14 and 21 months), and combination of growth traits (total height and DBH) and heteroblasty (proportion of adult foliage). The model was tested through the predictive capacity (estimated through intra-population cross-validation), the prediction bias (estimated as the regression coefficient between the reference breeding values and those predicted by the model), and the comparison between the rankings of breeding values from the conventional ABLUP and the ssGBLUP (as the proportion of common individuals in the top 10%). The heritabilities in the strict sense for all traits were high, ranging from 0.51 to 0.72. The predictive abilities of the different cross-validations by site and by trait were high, varying from 0.72 to 0.92. The model tends to slightly underestimate DBH and the proportion of adult foliage at some sites and overestimate them at others (bias between 0.88 and 1.19), and overestimate total height in all sites (bias between 0.51 and 0.68). The proportion of common individuals in the top 10% by conventional selection and GS is high for all traits (0.76 - 0.86). These results suggest that the incorporation of GS in the improvement plan of E. globulus would be efficient. It is proposed to include GS in two stages of the breeding cycle: the selection of the best parents for controlled mating, increasing the selection intensity, and the selection of individuals in the nursery, reducing the stage of field evaluation of the selected clones. This strategy will markedly reduce the selection cycle, allowing commercial clones to be obtained in half the time compared to conventional selection.

Adoption of a COVID-19 Contact Tracing App by Czech Youth: Cross-Cultural Replication Study.

During the worldwide COVID-19 pandemic crisis, the role of digital contact tracing (DCT) intensified. However, the uptake of this technology expectedly differed among age cohorts and national cultures. Various conceptual tools were introduced to strengthen DCT research from a theoretical perspective. However, little has been done to compare theory-supported findings across different cultural contexts and age cohorts. Building on the original study conducted in Belgium in April 2020 and theoretically underpinned by the Health Belief Model (HBM), this study attempted to confirm the predictors of DCT adoption in a cultural environment different from the original setting, that is, the Czech Republic. In addition, by using brief qualitative evidence, it aimed to shed light on the possible limitations of the HBM in the examined context and to propose certain extensions of the HBM. A Czech version of the original instrument was administered to a convenience sample of young (aged 18-29 y) Czech adults in November 2020. After filtering, 519 valid responses were obtained and included in the quantitative data analysis, which used structural equation modeling and followed the proposed structure of the relationships among the HBM constructs. Furthermore, a qualitative thematic analysis of the free-text answers was conducted to provide additional insights about the model's validity in the given context. The proposed measurement model exhibited less optimal fit (root mean square error of approximation=0.065, 90% CI 0.060-0.070) than in the original study (root mean square error of approximation=0.036, 90% CI 0.033-0.039). Nevertheless, perceived benefits and perceived barriers were confirmed as the main, statistically significant predictors of DCT uptake, consistent with the original study (β=.60, P<.001 and β=-.39; P<.001, respectively). Differently from the original study, self-efficacy was not a significant predictor in the strict statistical sense (β=.12; P=.003). In addition, qualitative analysis demonstrated that in the given cohort, perceived barriers was the most frequent theme (166/354, 46.9% of total codes). Under this category, psychological fears and concerns was a subtheme, notably diverging from the original operationalization of the perceived barriers construct. In a similar sense, a role for social influence in DCT uptake processes was suggested by some respondents (12/354, 1.7% of total codes). In summary, the quantitative and qualitative results indicated that the proposed quantitative model seemed to be of limited value in the examined context. Future studies should focus on reconceptualizing the 2 underperforming constructs (ie, perceived severity and cues to action) by considering the qualitative findings. This study also provided actionable insights for policy makers and app developers to mitigate DCT adoption issues in the event of a future pandemic caused by unknown viral agents.
