The unsettling fear of COVID-19 infections has caused a new trend in consumer behavior in the food and beverage industry. The unprecedented COVID-19 pandemic has shifted consumers’ preferences from eat-in to online delivery. This research aims to measure the impact of consumers’ motivation to protect themselves from contracting COVID-19, which explains why people switch from eat-in to online food delivery. We adopted the theory of protection motivation to explain consumer switching behavior during the COVID-19 pandemic. The present study investigated the (...) mediating effect of switching intention on the relationship between vulnerability, altruistic fear, anticipated regret, and switching behavior. Simultaneously, we examined the role of brand awareness as a moderator of behavioral choices of consumers switching from eat-in to online delivery. We collected data from 681 eatery consumers in Kuala Terengganu, Malaysia, using scenario-based survey questionnaires. Then, the data were analyzed using structural equation modeling. This new generation analysis was conducted using the analysis of moment structure and the statistical package for social science. The results indicated that consumer vulnerability, altruistic fear, and anticipated regret of COVID-19 increased consumers’ propensity to shift from eat-in to online food delivery. Allegedly, consumer behavioral control and intention of switching toward online delivery were pointedly affected by switching behavior. The results indicated that consumer vulnerability, altruistic fear, and anticipated regret of COVID-19 increased the shifting of restaurant dine-in patterns and made the intention to switch to online delivery. Consumers’ alleged behavioral control and their intention of switching toward online delivery were pointedly affected by switching behavior. We also found that brand awareness moderately affects switching behavior toward restaurant settings. The present research contributes to developing the consumer behavior model of switching from eat-in to online delivery. This study also provides eatery customers and the business community with a safer and healthier proposition of shifting to online food delivery during the pandemic. (shrink)

The COVID-19 pandemic is an unprecedented time in history. Surrounding this pandemic are many enormous uncertainties across the globe. Severe consequences have assessed for the incomes of almost 84% of employers and 68% of self-employed who are working and living in countries that are or have went through a phase of closing workplaces. Similarly, the global rate of unemployment is also expected to be increased in the coming years as 54% of employers worldwide are running their businesses in the hardest-hit (...) sectors. All of these clearly show the uneven impact of the Coronavirus crisis which will remarkably compound already present inequalities, difficulties, and vulnerabilities. The economic ramifications for 186 countries under the crunch of the COVID-19 pandemic is also considered tremendous for Pakistan. The core aim of this research was to test a new conceptual framework depicting the ramifications of restructuring processes carried out by management for their organizations amidst the COVID-19 pandemic on an Institute’s reputation as an employer brand. It also investigates the impact of perceived restructuring on a corporate brand promise made by the university or institute from the viewpoints of other key stakeholders and potential job seekers. The current study had proposed four hypotheses and according to the results of Structural Equation Modeling, the direct hypothesis based upon the relationship between restructuring and employer branding has been rejected. This study shows that restructuring and employer branding has a negative and insignificant effect on each other. The second direct hypothesis of the study that measures the effect of restructuring on corporate branding has been accepted. A corporate brand is a kind of a hub and it considers how an institute treats and deals with all of its stakeholders. It is different from employer brand as the perceptions of employees were the main focus. So, according to the results restructuring did not cause massive damage to the overall outlook of the institute. Furthermore, for the purpose of mediation analysis, the maximum likelihood method by bootstrapping was adopted to test the indirect hypotheses of the study. Crowdsourcing was introduced as a mediator in this study with restructuring, employer, and corporate brand all together in one framework, which is the novel aspect of this study. There are two indirect hypotheses and according to the results both of them did not show any insignificant results. Firstly, the study analyzed mediation among crowdsourcing, restructuring, and employer branding which was fully accepted as the results showed full mediation between these constructs. Secondly, the study analyzed mediation among crowdsourcing, restructuring, and corporate branding which was partially accepted as results showed partial mediation between these constructs. (shrink)

In this paper we study a notion of HL-extension for a structure in a finite relational language $\mathcal {L}$. We give a description of all finite minimal HL-extensions of a given finite $\mathcal {L}$ -structure. In addition, we study a group-theoretic property considered by Herwig–Lascar and show that it is closed under taking free products. We also introduce notions of coherent extensions and ultraextensive $\mathcal {L}$ -structures and show that every countable $\mathcal {L}$ -structure can be extended to a countable (...) ultraextensive structure. Finally, it follows from our results that the automorphism group of any countable ultraextensive $\mathcal {L}$ -structure has a dense locally finite subgroup. (shrink)

This paper analyzes perceptions of responsible leadership in eight Asia-based firms during the first year of the COVID-19 pandemic. The focal firms were a mixture of multinational corporations (MNCs), large-sized enterprises, and small and medium enterprises (SMEs). In all eight focal firms, we found that the responsible decision-making of leaders during the pandemic was perceived to be guided by five main moral principles. These comprised equity-based justice for employees, meeting employees’ basic needs, ethics of care for employees, concern for non-employee (...) stakeholders, and interactional justice for employees. We developed a conceptual map of how these principles related to aspects of four ethics-oriented leadership theories. Our analysis also identified four types of responsible leadership policies and practices. These comprised prioritizing the health and safety of stakeholders, flexible work arrangements, meeting employees’ and customers’ special needs, and financial and psychological support for employees.

In one of the earlier influential papers in the field of experimental philosophy titled Normativity and Epistemic Intuitions published in 2001, Jonathan M. Weinberg, Shaun Nichols and Stephen Stich reported that respondents answered Gettier type questions differently depending on their ethnic background as well as socioeconomic status. There is currently a debate going on, on the significance of the results of Weinberg et al. (2001) and its implications for philosophical methodology in general and epistemology in specific. Despite the debates, however, (...) to our knowledge, there has not been a replication attempt of the experiments of the original paper. We collected data from four different sources (two on-line and two in-person) to replicate the experiments. Despite several different data sets and in various cases larger sample sizes and hence greater power to detect differences, we failed to detect significant differences between the above-mentioned ethnic and socioeconomic groups. Our results suggest that epistemic intuitions are more robust across ethnic and socioeconomic groups than Weinberg et al. (2001) indicates. Given our data, we believe that the notion of differences in epistemic intuitions among different ethnic and socioeconomic groups that follows from Weinberg et al. (2001) needs to be corrected.

In their paper titled “Gender and philosophical intuition,” Buckwalter and Stich argue that the intuitions of women and men differ significantly on various types of philosophical questions. Furthermore, men's intuitions, so the authors claim, are more in line with traditionally accepted solutions of classical problems. This inherent bias, so the argument goes, is one of the factors that leads more men than women to pursue degrees and careers in philosophy. These findings have received a considerable amount of attention and the (...) paper is to appear in the second edition of Experimental Philosophy edited by Knobe and Nichols , which itself is an influential outlet. Given the exposure of these results, we attempted to replicate three of the classes of questions that Buckwalter and Stich review in their paper and for which they report significant differences. We failed to replicate the results using several different sources for data collection (one being identical to the original procedures.. (shrink)

Developmental processes in complex animals are directed by a hardwired genomic regulatory code, the ultimate function of which is to set up a progression of transcriptional regulatory states in space and time. The code specifies the gene regulatory networks (GRNs) that underlie all major developmental events. Models of GRNs are required for analysis, for experimental manipulation and, most fundamentally, for comprehension of how GRNs work. To model GRNs requires knowledge of both their overall structure, which depends upon linkage amongst regulatory (...) genes, and the modular building blocks of which GRNs are heirarchically constructed. The building blocks consist of basic transcriptional control processes executed by one or a few functionally linked genes. We show how the functions of several such building blocks can be considered in mathematical terms, and discuss resolution of GRNs by both “top down” and “bottom up” approaches.

In the spirit of Von Neumann and Morgenstern (Theory of games and economic behavior, Princeton University Press, Princeton, 1944), we introduce a notion of network stability. We study the structure of stable economic networks and their associated stable payoff allocations by analyzing the conditions under which complete networks and star networks (both with desirable property of inclusiveness) are stable. We also address conditions for existence and uniqueness of stable set of networks.

This paper addresses the issue of how to best account for the diversity of our (synchronic) mental activities. The discussion starts with Mark Textor’s mental monism. According to mental monism, our mental life is constituted by just one simple mental act, in which different sub-acts can be conceptually distinguished. Textor grounds this view in the work of the early Brentano and contrasts it with the theory of the later Brentano, who introduces a mental substance into his philosophy. According to Textor, (...) Brentano needs a substance because he is unable to explain how mental monism can account for the separability of our mental activities, e.g. the fact that I can stop hearing F while still seeing blue. Textor argues, however, that mental monism can solve this problem. I address two issues regarding Textor’s view. First, I challenge his interpretation of Brentano by arguing that the early Brentano imports ontological complexity into our mental life; I defend Brentano’s view against possible criticisms, and I address some objections to mental monism. Second, I oppose Textor’s narrative about the mental substance. I argue that Brentano needs a substance not to explain separability, but rather to individuate our mental acts. I still argue, however, that Brentano’s earlier view (understood in my sense) is better than the substance account for dividing the mind. (shrink)

The method of phenomenal contrast (in perception) invokes the phenomenal character of perceptual experience as a means to discover its contents. The method implicitly takes for granted that ‘what it is like’ to have a perceptual experience e is the same as ‘what it is like’ to imagine or recall it; accordingly, in its various proposed implementations, the method treats imaginations and/or recollections as interchangeable with real experiences. The method thus always contrasts a pair of experiences, at least one of (...) which is imagined or remembered rather than occurrent. Surveying all eighteen forms of implementing the method, I argue that in all of the proposed pairings, the substitution of imagination or recollection for perceptual experience in the method, is either inconceivable or impermissible. I identify four reasons why I think imagination cannot be substituted for real experience, and three reasons why recollection cannot be substituted for real experience. If my argument works, there is no form of implementing the method that is useful for discovering the contents of experience, and thus the method is not a well‐functioning tool to study the contents of perception.

Before the popularization of the printing press, the circula­tion of commentarial texts across regional borders, especially of Islamic texts outside of the Middle East, remains largely unexplored. This article focuses on the movement of Islamic manuscripts in the Indian Ocean world, from South and East Africa to South and East Asia. Together with merchants, sail­ors, travelers, and commodities, the books also traveled long distances, replete with ideas, stories, dreams, myths, norms, manners, and emotions. What was the role of manuscripts in (...) the expansion of Islam into the premodern oceanic world and in religio-cultural exchanges between central Islamic lands and the larger world? What sorts of books did people access, read, and use, and what did the circulation of these texts imply? I address these questions with a broad focus on the oceanic littoral and Islamic manuscripts and a specific focus on one of the ports and a legal commentary. Based on this analytical exercise of zooming-out and zooming-in between macro- and micro-maritime textual histories anchored in the sixteenth century, I argue that the citations of specific manuscripts reveal the prominence of a transregional circula­tion of certain texts, along with their contextual cultures of reading, writing, producing, and circulating commentaries.

This paper presents and evaluates the early Husserl’s account of typicality. In the Logical Investigations, Husserl holds that the meaning of ordinary language (common) names is sensitive to typicality: this meaning depends on typical examples which vary in different contexts and are more or less similar to one another. This seems to entail that meanings, which according to Husserl are concepts, are “fluctuating” (schwankend) and vague. Prima facie, such a claim contravenes his theory of ideal meanings, or concepts, which are (...) “fixed” (fest) and sharp. However, Husserl wants to save this theory. He claims that the fluctuation and vagueness in question are not to be found in the meaning itself, or the concept, but rather derive from the act of meaning. Thus, he apparently manages to make room for typicality in ordinary language while accepting only fixed and sharp meanings. After presenting Husserl’s theory, I evaluate it and ask whether he will still be committed, despite his own claims, to accepting prototype concepts to account for typicality in ordinary language.

Different aspects of competition in stock exchanges have been discussed from either a positive or normative perspective, but this article seeks to come up with an approach encompassing both positive and normative dimensions of competition in various aspects of stock exchanges' activities. As far as the positive nature of the securities market and industry is concerned, conflicting trends are emerging. The liberalization of securities markets and the disappearance of technical barriers have dismantled the monopoly of national stock exchanges but led (...) to more consolidation. However, we are also witnessing a destabilizing and fragmenting effect of competition on these markets. Following an analysis of the normative/positive dichotomy in approaching competition in financial services, we discuss the centrality of information disclosure in creating a competitive and stable financial market. Disclosure of information, therefore, reinforces both competitive and prudential objectives alike. In a further attempt, we discuss the tension between the principles of competition and prudence alongside the conflict between competition objectives and economies of scope and scale. While arguments in weighing competition against economies of scope and scale are evenly balanced, the unique characteristics of such markets do not allow the absolute application of competition principles when it comes to prudential concerns.

One of the earliest and most‐fundamental pattern‐ formation events in embryonic development is endoderm and mesoderm specification. In sea urchin embryos, this process begins with blimp1 and wnt8 gene expression at the vegetal pole as soon as embryonic transcription begins. Shortly afterwards, wnt8/blimp1 expression spreads to the adjacent ring of mesoderm progenitor cells and is extinguished in the vegetal‐most cells. A little later, the ring of wnt8/blimp1 activity moves out of the mesoderm progenitors and into the neighboring endoderm cells. Remarkably, (...) this moving ring of gene expression has now been shown to be controlled entirely by transcriptional cis‐regulatory logic.1.

Dilthey frequently recognizes anthropology as a foundational science of human nature and as a cornerstone in the system of the human sciences. While much has been written about Dilthey’s “philosophical anthropology,” relatively little attention has been paid to his views on the emerging empirical science of anthropology. This paper examines Dilthey’s relation to the new discipline by focusing on his reception of its leading German representatives. Using his book reviews, essays, and drafts for Introduction to the Human Sciences from the (...) 1860s-70s, it highlights the influence of the new anthropology on his earliest attempts to elaborate the foundations of the Geisteswissenschaften. It argues that anthropology was a key source for some of the naturalistic features of Dilthey’s philosophy, and that it pulled him in a direction contrary to the historicist hermeneutics of his teachers.

This paper argues that Wolff’s rejection of Leibnizian monads is rooted in a disagreement concerning the general notion of substance. Briefly, whereas Leibniz defines substance in terms of activity, Wolff retains a broadly scholastic and Cartesian conception of substance as that which per se subsists and sustains accidents. One consequence of this difference is that it leads Wolff to interpret Leibniz’s concept of a constantly striving force as denoting a feature of substance separate from its static powers, and not as (...) their replacement. For Wolff, powers are essential possibilities of acting in subjects suited for independent existence. Force is a further ingredient that provides a reason for the contingent operation of powers. Unlike Leibniz, Wolff conceives force narrowly as a principle of actuality, which he calls the nature of substance, as distinct from its principle of possibility, or essence. (shrink)

In this paper, we showcase our research on the use of ontologies and information extraction for the purpose of modeling damages incurred on car bodies. With the increasing use of technology in the automotive industry, it is important to have a standardized and efficient way of documenting and analyzing car damage reports. Most existing reports are unstructured, and there is a lack of standardization in describing the damage. To address this issue, we have developed a domain ontology for car damage (...) modeling (OCD),11 industryportal.enit.fr/ontologies/OCD,22 github.com/OntologyCarDamage/OCD and proposed an end-to-end system to extract information from French automotive reports. The information extraction process involves using named entity recognition (NER) and relationship extraction (RE) techniques to identify and extract relevant information from the reports. Then, the extracted information is used to populate the OCD ontology, allowing a structured and standardized representation of the damage information. The proposed system was tested on a real dataset of automotive reports and showed promising results. (shrink)

Global changes in capital, power, technology and the media have caused massive shifts in how we define home and community, leaving redrawn territories and globalized contexts. This interdisciplinary study of the media brings together essays by accomplished critics to discuss the way film, television, music, and computer and electronic media are shaping identities and cultures in an increasingly globalized world. Ranging from intensely personal to highly theoretical, the contributors explore our complex negotiation of "home" and homeland" in a postmodern world. (...)

This paper examines Kant’s treatment of the design argument for the existence of God, or physicotheology. It criticizes the interpretation that, for Kant, the assumption of intelligent design satisfies an internal demand of inquiry. It argues that Kant’s positive appraisal of physicotheology is instead better understood on account of its polemical utility for rebutting objections to practical belief in God upon which Kant’s ethicotheological argument rests, and thus as an instrument in the transition from theoretical to practical philosophy. Kantian physicotheology (...) plays this role a) by criticizing alternative speculative accounts of the ground of nature, and b) by analogizing from the structure of finite rational agency in order to represent more clearly the action of an ideal agent.

The turn to descriptive studies of ethics is inspired by the sense that our ethical theorizing needs to engage ethnography, history, and literature in order to address the full complexity of ethical life. This article examines four books that describe the cultivation of virtue in diverse cultural contexts, two concerning early China and two concerning Islam in recent years. All four emphasize the significance of embodiment, and they attend to the complex ways in which choice and agency interact with the (...) authority of tradition. In considering these books, this article examines the relations between our academic claims concerning the self and ethics, conceptual or theoretical claims made in the elite writings of traditions, and the lived experiences of the people we study. The conclusion turns to our methodological foundations for studying these topics both comparatively and constructively. (shrink)

In the famous Appendix to paragraphs 11 and 20 of his 5th Logical Investigation, Husserl criticizes the concept of ‘immanent object’ defended by Brentano and his pupils. Husserl holds that intentional objects, even non-existent ones, are ‘transcendent’. Yet long before Husserl’s criticism, Brentano and his pupils, in their theories of intentionality, besides immanent objects also took into account transcendent ones, in a similar way to Husserl, since such transcendent objects were not necessarily objects that exist. The ‘immanent object’ (immanenter Gegenstand) (...) was also called ‘presented-thing as presented’ (Vorgestelltes als Vorgestelltes), whereas the ‘transcendent object’ was called ‘object tout court’ (Gegenstand schlechtweg) or ‘presented-thing tout court’ (Vorgestelltes schlechtweg). Even if it is in Marty that one finds the clearest distinction between these two kinds of objects, other pupils of Brentano, and Brentano himself, made similar distinctions. Despite its importance, this point has been neglected in the Brentanian literature. In the first part of this article, I present the way in which immanent and transcendent objects have been distinguished in the School of Brentano. In the second part of the article, I present some problems linked to the distinction of two objects for every mental act, an immanent and a transcendent one; these problems could explain the abandonment of the notion of ‘immanent object’ by many philosophers of the Brentanian tradition. I conclude with some remarks on the distinction between content and object in the School of Brentano. (shrink)

Fronto-parietal activity has been frequently observed in fMRI and PET studies of attention, working memory, and episodic memory retrieval. Several recent fMRI studies have also reported fronto-parietal activity during conscious visual perception. A major goal of this review was to assess the degree of anatomical overlap among activation patterns associated with these four functions. A second goal was to shed light on the possible cognitive relationship of processes that relate to common brain activity across functions. For all reviewed functions we (...) observed a consistent and overlapping pattern of brain activity. The overlap was most pronounced for the bilateral parietal cortex , and dorsolateral prefrontal cortex . The common fronto-parietal activity will be discussed in terms of processes related to integration of distributed representations in the brain. (shrink)

This article argues that Clauberg defends the theory of concurrentism concerning the relationship between divine and secondary causality. It does so by examining Clauberg's theory of corporeal causation in light of his doctrines of cause in general and of corporeal substance. Clauberg's work represents one of the first attempts to reconcile Cartesian physics with the traditional doctrine in theology, according to which both God and created substances are true and immediate causes of all natural effects, in opposition to the occasionalist (...) trend which would soon develop in the Cartesian school as well as to the conservationist alternative of Durand de Saint-Pourçain. -/- Cet article soutient que Clauberg défend la théorie du concurrentisme sur la relation entre la causalité divine et la causalité seconde.

Many healthcare goods, such as surgical instruments, textiles and gloves, are manufactured in unregulated factories and sweatshops where, amongst other labour rights violations, workers are subject to considerable occupational health risks. In this paper we undertake an ethical analysis of the supply of sweatshop-produced surgical goods to healthcare providers, with a specific focus on the National Health Service of the United Kingdom. We contend that while labour abuses and occupational health deficiencies are morally unacceptable in the production of any commodity, (...) an additional wrong is incurred when the health of certain populations is secured in ways that endanger the health and well-being of people working and living elsewhere. While some measures have been taken to better regulate the supply chain to healthcare providers in the UK, further action is needed to ensure that surgical goods are sourced from suppliers who protect the labour and occupational health rights of their workers.

Corporate activities conducted under the banner of creating shared value (CSV) have gained popularity over the last decade, and some MNCs have espoused that CSV has entered the heart of their practices. There has, however, been criticism about the lack of a standard definition of CSV. The purpose of the current study was to develop a working definition of CSV by identifying distinctions between CSV and various conceptions of corporate social responsibility (CSR). We conducted 26 semi-structured interviews with managers and (...) stakeholder representatives of five multinational corporations (MNCs) and three small and medium enterprises (SMEs), all headquartered or rooted in Asia. These firms had received public recognition for their CSV engagement. We compared and contrasted interviewees’ conceptions and descriptions of CSV and traditional CSR (philanthropy) and mapped these against Carroll’s four-layer model of responsible corporate management. Interviewees tended to frame CSV as a sustainable business model that generates social and economic value simultaneously. Traditional CSR was characterized as “giving back” some of the surplus from economic returns. In addition, interviewees described examples of strategic CSR, which involved pump-priming interventions for empowering and enabling stakeholders of the CSV practices of the focal firm to participate in the associated wealth and well-being co-creation.

Aversion towards logic is a characteristic feature of the Islamic traditionalists. There is in fact a history of opposition to logic in Islam. As any other areas of history, here also the correct picture will not be achieved unless all of the pieces are put together.

This paper reconstructs and defends Kant's argument for the transcendental status of reason's principles of the systematic unity of nature in the Appendix to the Transcendental Dialectic. On the present account, these principles are neither mere methodological recommendations for conducting scientific inquiry nor do they have the normative force of categorical imperatives, two extant interpretations of Kant's discussion of reason in the Appendix. Instead, they are regulative yet transcendental principles restricted to theoretical cognition. The principles of the systematic unity of (...) nature count as transcendental in virtue of their role as conditions of the inferential articulation of empirical concepts. (shrink)

Emotions play vital roles in our psychology and our lives. They also often form the basis of our evaluative beliefs. On some views, emotions, like perceptions, justify the beliefs to which they give rise. It has, however, been claimed that, unlike perceptions, emotions are merely proxies for the genuine reasons that are constituted by their cognitive bases. In this paper, I argue that this objection arises from the failure to notice the difference between the notions of ‘reasons there are’ and (...) ‘possessed reasons’. After developing an account of what it is to possess a reason, it will be argued that emotions do constitute genuine reasons for the evaluative beliefs that result from them. To support this claim, a distinction is made between thinner and thicker descriptions of the same event, where a thinner description may be in terms of the emotional response, whereas a thicker description may be in terms of possessing a normative reason to hold a belief or to act.

For the safe and economical construction of embankment dams, the mechanical behaviour of the rockfill materials used in the dam’s shell must be analyzed. The characterization of rockfill materials with specified shear strength is difficult and expensive due to the presence of particles greater than 500 mm in diameter. This work investigates the feasibility of using an extreme gradient boosting computing paradigm to estimate the shear strength of rockfill materials. To train and validate the proposed XGBoost model, a total of (...) 165 databases obtained from the literature are chosen. The XGBoost model was compared against support vector machine, adaptive boosting, random forest, and K-nearest neighbor models described in the literature. XGBoost beats SVM, RF, AdaBoost, and KNN models in terms of performance evaluation metrics such as coefficient of determination, Nash–Sutcliffe coefficient, and error in the root mean square ratio to the standard deviation of the measured data. The results demonstrated that the XGBoost model has the highest prediction performance with, followed by the SVM model with, RF, the AdaBoost model with and the KNN model with. A sensitivity analysis has been conducted to ascertain the impact of each investigated input parameter. This study demonstrates that the established XGBoost model for estimating the shear strength of rockfill materials is reliable. (shrink)

Rockburst phenomenon is the primary cause of many fatalities and accidents during deep underground projects constructions. As a result, its prediction at the early design stages plays a significant role in improving safety. The article describes a newly developed model to predict rockburst intensity grade using Adaptive Boosting classifier. A database including 165 rockburst case histories was collected from across the world to achieve a comprehensive representation, in which four key influencing factors such as maximum tangential stress of the excavation (...) boundary, uniaxial compressive strength of rock, tensile rock strength, and elastic energy index were selected as the input variables, and the rockburst intensity grade was selected as the output. The output of the AdaBoost model is evaluated using statistical parameters including accuracy and Cohen's kappa index. The applications for the aforementioned approach for predicting the rockburst intensity grade are compared and discussed. Finally, two real-world applications are used to verify the proposed AdaBoost model. It is found that the prediction results are consistent with the actual conditions of the subsequent construction.

The applications of biotechnology are so broad, and the advantages so compelling, that virtually every industry is using this technology. Developments are under way in areas as diverse as pharmaceuticals, diagnostics, textiles, aquaculture, forestry, chemicals, household products, environmental cleanup, food processing, and forensics, to name a few. Biotechnology is enabling these industries to make new or better products, often with greater speed, efficiency, and flexibility. Biotechnology is any technological (...) application that uses biological systems, living organisms, or derivatives thereof to make or modify products or processes for specific use.

Anton Marty (1847-1914) is known to be the most faithful pupil of Franz Brentano. As a matter of fact, most of his philosophical ideas find their source in the works of his master. Yet, the faithfulness of Marty is not constant. As the rich correspondence between the two thinkers shows, Marty elaborates an original theory of intentionality from ca. 1904 onward. This theory is based on the idea that intentionality is a process of mental assimilation (ideelle Verähnlichung), a process at (...) the core of which lies a sui generis relation of “ideal similitude” holding between a thinking subject and its object. This study spells out the Martyian notion of mental assimilation and traces back Marty’s evolution from his earlier position (prominently described in the recently published Deskriptive Psychologie of 1893-1894) to his final view as it is found in the Untersuchungen of 1908. It turns out that besides Brentano, Husserl is a key figure in that evolution. Such a “genetic”elucidation of Marty’s last theory is required in order to reach the main goal of this paper, namely: the clarification of Marty’s degree of dependence upon Brentano with respect to the theory of intentionality. That being said, we do not merely intend to compare the mature Marty with Brentano: our “genetic” considerations will also allow us to describe the interaction between the two thinkers before 1904. Accordingly, we begin by presenting Brentano’s own position on intentionality in discussing its two currently competing readings, namely the “discontinuist” and the “continuist” one. Against a recent interpretation, we argue that Marty’s endorsement of a “discontinuist” reading is not based on a misunderstanding of Brentano’s position. (shrink)

The legal-ethical dynamism in Islamic law which allows it to respond to the challenges of modernity is said to reside in the institution of ijtihād (independent legal thinking and hermeneutics). However, jurists like Mohsen Kadivar and Ayatollah Faḍlalla have argued that the “traditional ijtihād” paradigm has reached its limits of flexibility as it allows for only minor adaptations and lacks a rigorous methodology because of its reliance on vague and highly subjective juridical devices such as public welfare (maṣlaḥa), imperative necessity (...) (ḍarūra), emergency (iḍtirār), need (ḥāja), averting difficulty (‘usr) and distress (ḥaraj), hardship (mashaqqa), and harm (ḍarar) without interrogating the fundamentals (uṣūl) of ijtihād. In contrast, in the “foundational ijtihād” model theology, ethics, intellect, epistemology, linguistics, hermeneutics, modern sciences, history, cosmology, anthropology, and the sources of Islamic legal theory (uṣūl al-fiqh) interact with one another to obtain resolutions that are just and non-discriminatory.

In recent years a new discussion on the nature of philosophical expertise has emerged: whether philosophers possess a special kind of expertise, what such expertise would entail, how to measure it, and related concerns. The aim of the present article is to clarify certain related points across these debates in the hope of paving a clearer path forward, by addressing the following. (1) The expertise defense, which seems central to many discussions on methodology and expertise, has been misconstrued at times. (...) (2) Questions of expertise and methodology could be separated more clearly.

(4) Finally, when viewed in light of methodological concerns, a new project emerges when engaging with recent contributions to the expertise debate. The present article attempts a brief outline of this project. (shrink)

In this study, a multiple model integration scheme supervised with a hybrid genetic algorithm-neural network was developed and employed to predict the accuracy of soil CEC in Tabriz plain, an arid region of Iran. The standalone models and extreme learning machine ) were implemented for (...) incorporation into the MM-GANN. In addition, it was tested to enhance the prediction accuracy of the standalone models. The soil parameters such as clay, silt, pH, carbonate calcium equivalent, and soil organic matter were used as model inputs to predict soil CEC. With the use of several evaluation criteria, the results showed that the MM-GANN model involving the predictions of ELM and ANN models calibrated by considering all the soil parameters as inputs provided superior soil CEC estimates with a Nash Sutcliffe Efficiency = 0.87, Root Mean Square Error = 2.885, Mean Absolute Error = 2.249, Mean Absolute Percentage Error = 12.072, and coefficient of determination = 0.884. The proposed MM-GANN model is a reliable intelligence-based approach for the assessment of soil quality parameters intended for sustainability and management prospects. (shrink)
