In a recent paper, Tuomas Tahko has argued for a hybrid view of the laws of nature, according to which some physical laws are metaphysically necessary, while others are metaphysically contingent. In this paper, we show that his criterion for distinguishing between these two kinds of laws — which crucially relies on the essences of natural kinds — is on its own unsatisfactory. We then propose an alternative way of drawing the metaphysically necessary/contingent distinction for laws of physics based on (...) the central kinematical/dynamical distinction used in physical theorising, and argue that the criterion can be used to amend Tahko’s own account, but also that it can be combined with different metaphysical views about the source of necessity.

A common feature of all standard theories of the laws of nature is that they are "absolutist": They take laws to be either all metaphysically necessary or all contingent. Science, however, gives us reason to think that there are laws of both kinds, suggesting that standard theories should make way for "non-absolutist" alternatives: theories which accommodate laws of both modal statuses. In this paper, we set out three explanatory challenges for any candidate non-absolutist theory and discuss the prospects of the (...) two extant candidates in light of these challenges. We then develop our own non-absolutist theory, the essentialist DTA account, which combines the nomic-necessitation or DTA account with an essentialist approach to metaphysical modality in order to meet the three explanatory challenges. Finally, we argue that the distinction between kinematical and dynamical laws found in physical theories supports both non-absolutism in general and our proposed essentialist DTA view in particular.

Grounding necessitarianism (GN) is the view that full grounds necessitate what they ground. Although GN has been rather popular among philosophers, it faces important counterexamples: For instance, A=[Socrates died] fully grounds C=[Xanthippe became a widow]. However, A fails to necessitate C: A could have obtained together with B=[Socrates and Xanthippe were never married], without C obtaining. In many cases, the debate essentially reduces to whether A indeed fully grounds C – as the contingentist claims – or if instead C is (...) fully grounded in A+, namely A plus some supplementary fact S (e.g. [Xanthippe was married to Socrates]) – as the necessitarian claims. Both sides typically agree that A+ necessitates C, while A does not; they disagree on whether A or A+ fully grounds C. This paper offers a novel defence of the claim that, in these typical cases, unlike A+, A fails to fully ground C – thereby bringing further support to GN. First and foremost, unlike A+, A fails to fully ground C because it fails to contain just what is relevant to do so, in two distinct senses – explanatory and generative relevance. Second, going for A, rather than A+, as a full ground undermines not just grounding necessitarianism, but modally weaker views which even contingentists may want to preserve. (shrink)

On what I call absolutist essentialism about modality (AE), the metaphysical necessities are the propositions that are true in virtue of the essence (i.e. Aristotelian, absolute essence) of some entities. Other kinds of necessity can then be defined by restriction – e.g. the conceptual necessities are the propositions that are true in virtue of the essence of conceptual entities specifically. As an account of metaphysical modality and some other kinds (e.g. logical, conceptual), AE may have important virtues. However, when it (...) comes to accounting for further important kinds, like natural or normative necessity, it faces a challenge. Three main options have been defended: treat those kinds as further restricted forms of metaphysical necessity; define them as conditional forms of metaphysical necessity; treat them as primitive kinds. -/- In this paper, I propose a new option, which combines the main idea of AE (reducing necessities to essences) with an idea which has been developed largely independently: that of relative essence. On the proposed view, those kinds (e.g. natural necessity) that cannot be grounded in the essences (i.e. absolute essences) of the relevant entities (e.g. natural entities) may be grounded in their relative essences instead. Thus, I propose a generalized, or extended, version of AE, which I call relativized essentialism about modality (RE). In particular, RE offers prospects for a general framework for kinds of modality which is flexible enough to cover a large range of kinds (both absolute and relative ones) while remaining parsimonious and unified.

Two approaches to elevating certain laws of nature over others have come to prominence recently. On the one hand, according to the meta-laws approach, there are meta-laws, laws which relate to laws as those laws relate to particular facts. On the other hand, according to the modal, or non-absolutist, approach, some laws are necessary in a stricter sense than others. Both approaches play an important role in current research, questioning the ‘orthodoxy’ represented by the leading philosophical theories of natural laws—Humeanism, (...) the DTA view, dispositional essentialism and primitivism. This paper clarifies the relations between these two emerging approaches, as well as their applicability to physical laws and the status of the challenges they pose for standard theories of laws of nature. We first argue that, despite some significant similarities between the two approaches (especially in the context of Lange’s counterfactual account of laws), they are in general distinct and largely independent of each other. Then, we argue that the support for meta-laws from physical theory and practice is more questionable than usually presented. (shrink)

Il s'agit d'interroger la topique d'assignation homologique et pédagogique souvent faite entre la naïveté de l'interrogation curieuse du philosophe et l'ingénuité épistémique de l'absence de préjugés de représentations de l'enfance et ainsi de comparer les modes d'approches ontologiques des phénomènes du monde et de la vie logique. Y a-t-il dans l'usage critique du concept chez le philosophe une rémanence fondamentale et spéculative de l'interrogation anthropologique et métaphysique de l'enfant sur le cosmos, l'être, et l'apparition des étants dans la sphère de (...) son vécu historique de la réalité?

Abstract: Over the past fifty years in developing world, the role of the state intervention in promoting economic growth and social progress has been a subject of disputing among political elites, international development experts and policy analysts. Recognition of the economic growth success of East Asia has led to new thinking on what developmental states idea should be accomplished. The observable optimism performance of East Asian Tigers on the contextual of developmental states is keen in the fact that economic growth (...) can be achievable when states commitment is concerned with respect to capitalist based economy. Since Tanzania is in a unique position of possessing some resources in which other East Asian Tigers did not posses thou their commitment and high standard of responsibility were imperative to their success. It is in this line therefore this paper attempts to draw attentions of Tanzanian Elites and Policy makers on how they can learn from the story of development states in East Asia so as to invent it into the development agenda in building sustainable development for the people of Tanzania.

Purpose: A retraction is the removal of a published article from the scientific record. It is an admission of failure. Yet, every retraction, regardless of its cause(s), is instructive. Using the oxymoron/concept of celebrating failure, this study investigates retractions in the Journal of Consumer Research (JCR). -/- Method: The content of each JCR retraction notice was examined to determine the initiator(s) of the retraction, retractors, reason(s) for retraction, and time-to-retraction. -/- Findings: According to the findings, JCR issued ten retraction notices (...) between June 2012 and October 2020. The ten retraction notices generated together, and up to April 11, 2022, some 18,378 pageviews, 3,944 PDF. (shrink)

Abstract: Many scholars and practitioners are concerned with understanding how and when to motivate individuals to be more creative. We argue that the conflicting ideas may be due to differences between findings towards reward conditions and the situation in which rewards has to be offered. Hence, it is vital to portray in this study that motivating employees to be creative is important for many firms. Amount of literature shows that employee performance can be encouraged by extrinsic and intrinsic rewards in (...) their everyday tasks. This paper, therefore, investigates these kinds of rewards and shows its effectiveness in attracting creative performance. It concluded by arguing that, human behaviors are stimulated by extrinsic motivations attained from works, which are capable to fulfill innate parts of individuals. Similarly, a person is intrinsically motivated when he or she found that the work is able to fulfill his or her psychological needs for the significant experience. (shrink)

Abstract : Background: Vegetable agriculture is very important to human continued existence and remains a key driver of many economies worldwide, especially in underdeveloped and developing economies. Objectives: There is an increasing demand for food and cash crops, due to the increasing in world population and the challenges enforced by climate modifications, there is an urgent need to increase plant production while reducing costs. Methods: In this paper, Lemon classification approach is presented with a dataset that contains approximately 2,000 images (...) belong to 3 species at a few developing phases. Convolutional Neural Network (CNN) algorithms, a deep learning technique extensively applied to image recognition was used, for this task. The results: found that CNN-driven lemon classification applications when used in farming automation have the latent to enhance crop harvest and improve output and productivity when designed properly. The trained model achieved an accuracy of 99.48% on a held-out test set, demonstrating the feasibility of this approach. (shrink)
