Flavour spectrum of the Puff family of disposable e-cigarettes

BackgroundIn January 2020, the US Food and Drug Administration prohibited the sale of flavours (except for menthol and tobacco) in prefilled pod devices such as JUUL to decrease youth vaping. Excluded from the prohibition were disposable devices.ObjectivesTo determine the scope and scale of flavours marketed by Puff Bar, a leading disposable brand, and related products.MethodsDisposable e-cigarette flavours were identified via online searches encompassing vendor websites, wholesale distributors, manufacturers (eg, made-in-china.com), and social media channel, Instagram, between June and August 2020.ResultsThe ‘Puff’ brand name and iconic cloud logo appear on a variety of products of differing sizes and nicotine e-liquid volumes. Among Puff Bar and its copycats (Puff-a-Likes), 139 flavours were identified. Fruit flavours predominated comprising 82.2% of the flavour varieties (fruit 50%, fruit and menthol/mint 23.6%, and fruity drinks 8.6%). A prevalent new flavour category which combines fruit with menthol/mint (Ice) was offered in 33 varieties such as Lychee Ice, Lush Ice and Banana Ice. Disposable e-cigarette brands are undertaking measures to escape tobacco regulation (eg, non-tobacco-sourced nicotine) and flavour limitations via post-market flavour additions to unflavoured nicotine e-liquid.ConclusionsThe proliferation of flavoured disposable e-cigarette products, many of which are designed to emulate popular pod devices, illustrates that narrowly limited flavour regulations covering only a single category are destined to fail. To be effective in youth protection, flavour regulations need to apply to all recreational nicotine-containing products and need to include measures to counter post-market flavour addition.

A novel convolutional neural network for electronic component classification with diverse backgrounds

The rapid development of computer vision techniques has brought new opportunities for manufacturing industries, accelerating the intelligence of manufacturing systems in terms of product quality assurance, automatic assembly, and industrial robot control. In the electronics manufacturing industry, intensive variability in component shapes and colors, background brightness, and visual contrast between components and background results in difficulties in printed circuit board image classification. In this paper, we apply computer vision techniques to detect diverse electronic components from their background images, which is a challenging problem in electronics manufacturing industries because there are multiple types of components mounted on the same printed circuit board. Specifically, a 13-layer convolutional neural network (ECON) is proposed to detect electronic components either of a single category or of diverse categories. The proposed network consists of five Convolution-MaxPooling blocks, followed by a flattened layer and two fully connected layers. An electronic component image dataset from a real manufacturing company is applied to compare the performance between ECON, Xception, VGG16, and VGG19. In this dataset, there are 11 categories of components as well as their background images. Results show that ECON has higher accuracy in both single-category and diverse component classification than the other networks.

The Older, the More Forgiving? Characteristics of Forgiveness of Chinese Older Adults

This study explores the characteristics of forgiveness in the aging cohorts, which is regarded to be associated with healthy outcomes. Data were drawn from a sample of 308 older adults (aged from 60 to 98 years) who completed the forgiveness questionnaire: forgiving others of The Heartland Forgiveness Scale (HFS) to examine explicit forgiveness, and among the participants, 44 older adults were administrated on the variant single category of implicit association test (SC-IAT) to examine the implicit forgiveness. The results revealed that (1) there is no correlation between explicit forgiveness and implicit forgiveness of older adults. (2) The result of explicit forgiveness is relatively high while that of implicit forgiveness is relatively low. (3) There was no significant correlation between explicit forgiveness and age, but there was significant difference between age groups, as forgiveness tendency of the elderly had a trough in the age group of 70–79 and then rebounded. (4) Implicit forgiveness was significantly correlated with age, and the difference between age groups was marginal. The forgiveness tendency of the elderly over 80 years old was significantly higher than that of the other two age groups. (5) Gender differences are found in both explicit and implicit forgiveness. The findings indicated that (1) explicit and implicit measures in this study have assessed independent and complementary aspects of forgiveness tendency in older adults. (2) Implicit forgiveness falls behind explicit forgiveness, and true internal forgiveness is difficult and rare in older adults according to data analysis. (3) The trend of explicit forgiveness with age is not obvious, because explicit forgiveness in the middle old age group presents an inflection point. However, implicit forgiveness increases slowly with age. (4) Women excel men in scores obtained with both explicit and implicit measures for forgiveness.

Sexual Misconduct: What the Qur’an Tells Us about Pre-marital vs Extra-Marital Sex

In the Qur’an, sex outside marriage is a topic addressed to men and women equally, although society has come down much harder on women in this regard. A distinction is made between pre-marital and extra-marital sex (adultery), yet we hear almost nothing about that, with the two typically collapsed into a single category in the public discourse. While four witnesses are required to prove illicit sex of any kind, a mere expression of remorse is sufficient for the accused to be left alone per Qur’anic dictate. Where remorse is absent, the Qur’an takes a harder line against extra-marital sex and instructs “flogging”, an act of (limited) public shaming undertaken with harmless instruments, per the historical record, rather than the commonly held belief that its intention was corporal harm. How could it be otherwise, anyway, since women are prescribed the same number of “lashes” as men despite the physical differences between the two? As for stoning, it is not mentioned anywhere in the Qur’an.

New science of art of Hans Sedlmayr

This article provides a brief systemic analysis of the key concepts of the so-called new science of art developed by the Austrian art historian Hans Sedlmayr. The result of Seldmayr’s pursuits are reflected in creation of his own philosophy of art and culture based on a particular worldview. The cognition of the whole, along with individual and unique, underlies this science. Understanding is the goal of scientific knowledge for Sedlmayr. It suggests not only abstract knowledge, but peculiar existential experience as well. Sedlmayr interprets the understanding of artwork as its contemplation, which in turn, is identical to its actualization or presence. In Seldlmayr’s art of science, epistemologies and ontologies merge into each other. He interprets artworks simultaneously as the event and as the social organism, which overcomes the linearity of time and fragmentation of plurality. This artificial complex system, built on the paradoxical identity of the single and plenty, is both finite and infinite. Sedlmayr’s views encompass classical and nonclassical approach towards cognition of the whole. He relies on the principles of monism, seeking to reduce all concepts to a single basis, single point of singularity that designates the synthesis of all the moments of the whole and can be expressed by a single category. The main category, which resembles the center of the opposites, is the “midpoint” (Mitte). The aforementioned ideas are consistent and logical only in such scientific worldview that identifies ontology and epistemology, which implies the unity of contemplation and phenomenon of the artwork. Therefore, in Sedlmayr's constructions, actualization or revival of the artwork is identical with its comprehension. The systemic approach towards the artwork reflected in the theoretical works of Sedlmayr extends the boundaries of art science and converges with philosophy.

A Matter of Transition: Authenticity Judgments and Attracting Employees to Hybridized Organizations

Category-spanning organizations have been shown to face a number of penalties compared with organizations occupying a single category. The assumption seems to be, however, that organizations spanning the same categories will be evaluated similarly. Yet, this is not always the case. We know far less about why evaluations may differ within category-spanners, largely due to existing studies’ focus on comparing single-category to category-spanning organizations in equilibrium states at a fixed point in time. Instead, this paper investigates audience judgments of organizations as they transition from single to multiple categories. We rely on the empirical setting of social-commercial hybrids—an intriguing context in which to explore category-spanning across market and nonmarket domains associated with distinct values, norms, and expectations. In a series of two experimental studies, we investigate how hybridization affects audience judgments of organizational authenticity and the ability to attract potential employees. We find that across organizational fields associated with nonprofit (communal) and for-profit (market exchange) norms, hybridization—more than hybridity itself—triggers audience cynicism and leads to decreased judgments of authenticity. However, the penalties for hybridizing are only observed when organizations also move away from field-level profit-status norms. The findings contribute to the category-spanning and authenticity literatures by integrating social psychological and organizational theory perspectives to offer a dynamic view of spanning beyond for-profit, market contexts. They also offer empirical support for the theorized multidirectionality of mission drift in hybrid organizations, while suggesting that drifting need not always be detrimental.

Orphan Classes, Chameleon Stems, Ghost Controllers, Adverbial Classes, and Versatile Relativizers in Jóola Fóoñi (Atlantic)

The traditional approach to Niger-Congo gender systems conflates the number markers of nouns and the gender-number markers of adnominals and pronouns into a single category of ‘class markers’. Using Jóola Fóoñi as an illustration, this paper discusses several types of phenomena commonly found in these systems that are problematic for the traditional notion of noun class and support the necessity of a revision of the conceptual and terminological framework commonly used in the description of Niger-Congo gender systems.

Political Purposes, Anti-entrenchment and Judicial Protection of the Democratic Process

The legality of decisions made for political purposes is a recurring issue in administrative law. In this article, it will be argued that generalisations should not be made about ‘political’ decisions as a single category. Instead, there are different types of political consideration, which raise different issues when assessing the legality of a decision. This article singles out a particular type of political decision for condemnation: decisions made to gain a political advantage by deliberately changing the systems of democratic accountability. Examples include the engineering of the electoral system to produce favourable results, the use of public power to punish critics and the use of public resources to publish partisan propaganda. The article will argue that the legality of such political decisions should not be assessed solely within the ordinary administrative law framework, but under a constitutional principle of anti-entrenchment and process protection.

The genomic ecosystem of transposable elements in maize

Transposable elements (TEs) constitute the majority of flowering plant DNA, reflecting their tremendous success in subverting, avoiding, and surviving the defenses of their host genomes to ensure their selfish replication. More than 85% of the sequence of the maize genome can be ascribed to past transposition, providing a major contribution to the structure of the genome. Evidence from individual loci has informed our understanding of how transposition has shaped the genome, and a number of individual TE insertions have been causally linked to dramatic phenotypic changes. Genome-wide analyses in maize and other taxa have frequently represented TEs as a relatively homogeneous class of fragmentary relics of past transposition, obscuring their evolutionary history and interaction with their host genome. Using an updated annotation of structurally intact TEs in the maize reference genome, we investigate the family-level dynamics of TEs in maize. Integrating a variety of data, from descriptors of individual TEs like coding capacity, expression, and methylation, as well as similar features of the sequence they inserted into, we model the relationship between attributes of the genomic environment and the survival of TE copies and families. In contrast to the wholesale relegation of all TEs to a single category of junk DNA, these differences reveal a diversity of survival strategies of TE families. Together these generate a rich ecology of the genome, with each TE family representing the evolution of a distinct ecological niche. We conclude that while the impact of transposition is highly family- and context-dependent, a family-level understanding of the ecology of TEs in the genome can refine our ability to predict the role of TEs in generating genetic and phenotypic diversity.
