This paper presents an adaptive fuzzy sliding-mode controller for multiple Euler–Lagrange systems communicated with directed topology. Based on the graph theory and Lyapunov–Krasovskii functions, a delay-dependent sufficient condition for the existence of sliding surfaces is given in terms of linear matrix inequalities. The asymptotic stability is analyzed by using the Lyapunov method in the presence of unknown parametric dynamics, actuator faults, and time-varying delays. The usage of adaptive techniques is to adapt the unknown parameters so that the objective of globally (...) asymptotic stability is achieved. Finally, simulation results are provided to illustrate the effectiveness of the proposed control scheme. (shrink)

Good agricultural practices certification schemes have been promoted to enhance agricultural sustainability. This study seeks to explain the adoption of GAP certification schemes through an analysis of the role of personal values in guiding such choice. It is a departure from approaches taken in previous studies in the area. Through the laddering interview technique of means-end chain analysis, a hierarchical value map was systematically schematized to illustrate the relationship between adoption of GAP, outcomes, and personal values driving the choice. The (...) personal values identified in this study cluster under the headings of “better life”, “religious responsibility”, “healthy life”, and “responsible farmer”. Amongst these, the main evidence pointed to the desire to have “better life” through the enhanced financial position that is perceived to arise as a consequence of GAP adoption as being of primary importance. These findings suggest that, while profit is not the sole end driver of adoptive behavior, GAP certification schemes have to be seen as lucrative and to enhance the goals of achieving core personal values. Other empirical information in this study also has significant policy implications. It is a key finding of this paper that effective promotions of GAP should be tailored and targeted at specific segments of the farmer population. (shrink)

The secretory pathway delivers proteins synthesized at the rough endoplasmic reticulum (RER) to various subcellular locations via the Golgi apparatus. Currently, efforts are focused on understanding the molecular machineries driving individual processes at the RER and Golgi that package, modify and transport proteins. However, studies are routinely performed using non‐dividing cells. This obscures the critical issue of how the secretory pathway is affected by cell division. Indeed, several studies have indicated that protein trafficking is down‐regulated during mitosis. Moreover, the RER (...) and Golgi apparatus exhibit gross reorganization in mitosis. Here I provide a relatively neglected perspective of how the mitotic cyclin‐dependent kinase (CDK1) could regulate various stages of the secretory pathway. I highlight several aspects of the mitotic control of protein trafficking that remain unresolved and suggest that further studies on how the mitotic CDK1 influences the secretory pathway are necessary to obtain a deeper understanding of protein transport.

This essay examines how eighteenth-century naturalists selected, read, and used textual and visual sources of the past to construct chronologies of the aurora borealis from antiquity to their present. Frequent sightings of the northern lights in Europe from 1707 onward prompted investigations into not only their physical properties but also their historical patterns. These searches encountered a twofold problem. Because the term “aurora borealis” was a seventeenth-century neologism, the recovery of auroras avant la lettre required discerning them amid the various (...) aerial spectacles described in older records. Further complicating the task was the eighteenth-century authors’ suspicion of these documents as tainted by the superstitions of an “unenlightened” past. Nevertheless, these self-proclaimed “enlightened” commentators relied on the very sources they criticized in their search for lost auroras. The essay investigates how different Enlightenment auroral observers fashioned their own criteria for identifying “true” auroras through practices of extricating verbal and visual descriptions in older sources from their original contexts of portentous interpretation.

According to Hobbes, individuals care about their relative standing in a way that shapes their social interactions. To model this aspect of Hobbesian psychology, this paper supposes that agents have social preferences, that is, preferences about their comparative resource holdings. Introducing uncertainty regarding the social preferences of others unleashes a process of trust-unravelling, ultimately leading to Hobbes’s ‘state of war’. This Trust-unravelling Model incorporates important features of Hobbes’s argument that past models ignore.

Scholars have generally underestimated the level of Roman involvement in Africa in the period between the annexation of Carthage in 146 b.c. and Caesar's victory at Thapsus in 46 b.c., and the land in Africa which the Romans annexed has been conventionally called public land (ager publicus). This paper analyses the surviving text of the African provisions of the epigraphic lex agraria of 111 b.c. and notes that the term ager publicus is not attested in the provincial section of the (...) law. The land in Africa appears simply as ager in Africa and the term ager publicus is confined exclusively to Italy in the law of 111. However, Cicero's references to Rullus’ agrarian proposal in 64/3 b.c. in the De lege agraria suggest that the term ager publicus was used to qualify land existing outside Italy in Rullus’ proposal. This paper argues that the concept of ager publicus as opposed to private land developed in Africa between 111 and 63 b.c., and that this was linked to privatization of ager in Africa in this period. The results of this study suggest a high degree of Roman exploitation of African land prior to the Caesarean and Augustan colonies in the 40s b.c. (shrink)

Ideological indoctrination is explicit and pervasive in China, with the school curriculum used to mould the spirit and character of adolescents, fulfilling ideological and political purposes. But the exact content varies over time. Comparing two versions of textbooks published in 1997 and 2005, this paper depicts the continuities and change in the curricular discourses centred on the notion of ‘good citizen’. While keeping the official status of socialism and the Party leadership untouched, the new textbooks soften the presentation and packaging (...) of the ideological content, very much in tandem with the soft authoritarianism practised since the post‐Deng era when China has been deeply involved in the processes of marketisation, liberalisation and globalisation. The new textbooks also adopt a stance of greater reconciliation with human rights and global citizenship. While being granted more autonomy and rights, young citizens are still expected to shoulder the mission of national revival and socialist modernisation—very much derived from official policies.

When Western Christianity came to Asia, it merged with Eastern religions and histories and developed very differently in different places. Today Asian women in each country build up very unique images of God. They practice Eastern forms of worship and liturgical rites, and do indigenized theologies. They simultaneously try to find their own ways of naming, imaging, believing in and communicating with their own God. Korean Christianity has inherited many images of God from Western Christian doctrines and theologies. However, when (...) it meets and merges with Koreanized Buddhism, Confucianism, and Shamanism, some of the images of God in Christianity are transformed and re-imagined in Korean women's social cultural and religious contexts. As an Asian woman, especially a Korean woman, I would like to introduce one of the many Asian women's theologies, Korean women's images of God. It cannot represent all Asian women's ways of doing theologies, but it will give some clues to show how Asian women do theologies in their own context. In particular, I will examine three images of God that demonstrate how Western Christianity and Eastern religions meet and are transformed in Korean Christian women's living contexts. (shrink)

What constitutes a good life? A hedonist’s answer to this question is rather simple— more pleasure, less pain. While hedonism was previously a widely accepted belief, it now suffers from several crucial objections. A challenge particularly vexing to hedonists is the Philosophy of Swine: could it be possible that our lives may be less than that of a theoretical swine? In this essay, I argue that lifetime hedonism, the view of hedonism concerned with one’s total lifelong well-being, does not survive (...) this objection. In particular, I will refute the counterarguments that modern-day hedonist, Ben Bramble, presents against the Philosophy of Swine objection. (shrink)

Matarese (2022) argued in a commentary that Machery’s (2020) resampling account of replication (RAR) is unsatisfactory because it was too quick to abolish the distinction between direct and conceptual replications. Although Matarese agrees with Machery that some interpretations of conceptual replications are misconceived, she offers an interpretation which purports to show that direct and conceptual replications have different functions, and this justifies preserving the distinction. In this commentary, I will defend the RAR from Matarese’s argument. Most importantly, I will argue (...) that Matarese’s interpretation of conceptual replications is conceptually impossible. Thus, I conclude that the direct–conceptual distinction was rightly abolished by Machery. (shrink)

Volatile compounds, such as nitric oxide and ethylene gas, play a vital role as signaling molecules in organisms. Ethylene is a plant hormone that regulates a wide range of plant growth, development, and responses to stress and is perceived by a family of ethylene receptors that localize in the endoplasmic reticulum. Constitutive Triple Response 1 (CTR1), a Raf‐like protein kinase and a key negative regulator for ethylene responses, tethers to the ethylene receptors, but undergoes nuclear translocation upon activation of ethylene (...) signaling. This ER‐to‐nucleus trafficking transforms CTR1 into a positive regulator for ethylene responses, significantly enhancing stress resilience to drought and salinity. The nuclear trafficking of CTR1 demonstrates that the spatiotemporal control of ethylene signaling is essential for stress adaptation. Understanding the mechanisms governing the spatiotemporal control of ethylene signaling elements is crucial for unraveling the system‐level regulatory mechanisms that collectively fine‐tune ethylene responses to optimize plant growth, development, and stress adaptation.

Cellular events must be executed in a certain sequence during the cell division in order to maintain genome integrity and hence ensure a cell's survival. In M phase, for instance, chromosome segregation always precedes mitotic exit (characterized by mitotic kinase inactivation via cyclin destruction); this is then followed by cytokinesis. How do cells impose this strict order? Recent findings in budding yeast have suggested a mechanism whereby partitioning of chromosomes into the daughter cell is a prerequisite for the activation of (...) mitotic exit network (MEN). So far, however, a regulatory scheme that would temporally link the initiation of cytokinesis to the execution of mitotic exit has not been determined. We propose that the requirement of MEN components for cytokinesis, their translocation to the mother–daughter neck and triggering of this translocation by inactivation of the mitotic kinase may be the three crucial elements that render initiation of cytokinesis dependent on mitotic exit.

Community engagement (CE) is gaining prominence in global health research. A number of ethical goals–spanning the instrumental, intrinsic, and transformative–have been ascribed to CE in global health research. This paper draws attention to an additional transformative value that CE is not typically linked to but that seems very relevant: solidarity. Both are concerned with building relationships and connecting parties that are distant from one another. This paper first argues that furthering solidarity should be recognized as another ethical goal for CE (...) in global health research. It contends that, over time, CE can build the bases of solidaristic relationships—moral imagination, recognition, understanding, empathy—between researchers and community members. Applying concepts from existing accounts of solidarity, the paper develops preliminary ideas about who should be engaged and how to advance solidarity. The proposed approach is compared to current CE practice in global health research. Finally, the paper briefly considers how solidaristic CE could affect how global health research is performed.

The current study examined the validity of HEXACO personality traits (at the broad trait-level and narrow facet-level) and Self-Control as predictors of counterproductive academic behavior (CAB; at the overall level and specific dimensional level) among college students. We collected data from 483 undergraduate students in South Korea who completed self-report measures of HEXACO personality traits, Self-Control, CAB. Results showed that Conscientiousness (_r_ = −.23) and Honesty-Humility (_r_ = −.25) were significantly correlated with CAB and that Self-Control provided incremental validity over (...) HEXACO personality traits in predicting CAB. The correlations of Conscientiousness and Self-Control with CAB were consistently negative at the facet-level. However, within each HEXACO trait, there was some variability in the strength (and sometimes, the direction) of the relationships between the facet traits and CAB dimensions. Additionally, hierarchical multiple regression analysis results showed that Self-Control provided incremental validity for predicting CAB beyond prediction provided by the HEXACO personality traits. The results provide further support for personality and Self-Control as meaningful predictors of counterproductive academic behavior in college. (shrink)

BackgroundAn increasing number of studies utilize intracranial electrophysiology in human subjects to advance basic neuroscience knowledge. However, the use of neurosurgical patients as human research subjects raises important ethical considerations, particularly regarding informed consent and undue influence, as well as subjects’ motivations for participation. Yet a thorough empirical examination of these issues in a participant population has been lacking. The present study therefore aimed to empirically investigate ethical concerns regarding informed consent and voluntariness in Parkinson’s disease patients undergoing deep brain (...) stimulator (DBS) placement who participated in an intraoperative neuroscience study.MethodsTwo semi-structured 30-minute interviews were conducted preoperatively and postoperatively via telephone. Interviews assessed participants’ motivations for participation in the parent intraoperative study, recall of information presented during the informed consent process, and participants’ postoperative reflections on the research study.ResultsTwenty-two participants (mean age = 60.9) completed preoperative interviews at a mean of 7.8 days following informed consent and a mean of 5.2 days prior to DBS surgery. Twenty participants completed postoperative interviews at a mean of 5 weeks following surgery. All participants cited altruism or advancing medical science as “very important” or “important” in their decision to participate in the study. Only 22.7% (n = 5) correctly recalled one of the two risks of the study. Correct recall of other aspects of the informed consent was poor (36.4% for study purpose; 50.0% for study protocol; 36.4% for study benefits). All correctly understood that the study would not confer a direct therapeutic benefit to them.ConclusionEven though research coordinators were properly trained and the informed consent was administered according to protocol, participants demonstrated poor retention of study information. While intraoperative studies that aim to advance neuroscience knowledge represent a unique opportunity to gain fundamental scientific knowledge, improved standards for the informed consent process can help facilitate their ethical implementation.

What are the effects of word-by-word predictability on sentence processing times during the natural reading of a text? Although information complexity metrics such as surprisal and entropy reduction have been useful in addressing this question, these metrics tend to be estimated using computational language models, which require some degree of commitment to a particular theory of language processing. Taking a different approach, this study implemented a large-scale cumulative cloze task to collect word-by-word predictability data for 40 passages and compute surprisal (...) and entropy reduction values in a theory-neutral manner. A separate group of participants read the same texts while their eye movements were recorded. Results showed that increases in surprisal and entropy reduction were both associated with increases in reading times. Furthermore, these effects did not depend on the global difficulty of the text. The findings suggest that surprisal and entropy reduction independently contribute to variation in reading times, as these metrics seem to capture different aspects of lexical predictability.

This article discusses three policy ideas that address the limitations of the traditional welfare state: universal basic income (UBI), universal basic services (UBS), and the social economy. As a lens from which to evaluate these policy alternatives, we develop a concept of active citizenship as an interactive and recursive process between people’s equal political influence and the institutional conditions in which they are placed. While the social policy discourse on active citizenship has centred on the debate between increasing individual responsibilities (...) or enhancing people’s capabilities, our conception recentres the political dimension of active citizenship as people’s capacity, not only to exercise individual self-determination, but also collective self-determination over shared conditions. We conclude that, in addition to the conditions for security and autonomy, opportunities for organised social cooperation are necessary to achieve a virtuous cycle between people’s political influence and the institutions that support it.

BackgroundSharing de-identified individual-level health research data is widely promoted and has many potential benefits. However there are also some potential harms, such as misuse of data and breach of participant confidentiality. One way to promote the benefits of sharing while ameliorating its potential harms is through the adoption of a managed access approach where data requests are channeled through a Data Access Committee (DAC), rather than making data openly available without restrictions. A DAC, whether a formal or informal group of (...) individuals, has the responsibility of reviewing and assessing data access requests. Many individual groups, consortiums, institutional and independent DACs have been established but there is currently no widely accepted framework for their organization and function.Main textWe propose that DACs, should have the role of both promotion of data sharing and protection of data subjects, their communities, data producers, their institutions and the scientific enterprise. We suggest that data access should be granted by DACs as long as the data reuse has potential social value and provided there is low risk of foreseeable harms. To promote data sharing and to motivate data producers, DACs should encourage secondary uses that are consistent with the interests of data producers and their own institutions. Given the suggested roles of DACs, there should be transparent, simple and clear application procedures for data access. The approach to review of applications should be proportionate to the potential risks involved. DACs should be established within institutional and legal frameworks with clear lines of accountability, terms of reference and membership. We suggest that DACs should not be modelled after research ethics committees (RECs) because their functions and goals of review are different from those of RECs. DAC reviews should be guided by the principles of public health ethics instead of research ethics.ConclusionsIn this paper we have suggested a framework under which DACs should operate, how they should be organised, and how to constitute them.

Research funders, regulatory agencies, and journals are increasingly expecting that individual-level data from health research will be shared. Broad consent to such sharing is considered appropriate, feasible and acceptable in low- and middle-income settings, but to date limited empirical research has been conducted to inform the design of such processes. We examined stakeholder perspectives about how best to seek broad consent to sharing data from the Mahidol Oxford Tropical Medicine Research Unit, which implemented a data sharing policy and broad consent (...) to data sharing in January 2016. Between February and August 2017 qualitative data were collected at two sites, Bangkok and the Thai-Myanmar border town of Mae Sot. We conducted eighteen semi-structured interviews. We also conducted four focus group discussions with a total of nineteen people. Descriptive and thematic coding informed analysis of aspects of data sharing that are considered most important to inform participants about, and the best ways to explain complex and abstract topics relating to data sharing. The findings demonstrated that clinical trial participants prioritise information about the potential benefits and harms of data sharing. Stakeholders made multiple suggestions for clarifying information provided about data sharing on such topics. There was significant variation amongst stakeholders’ perspectives about how much information should be provided about data sharing, and it was clear that effective information provision should be responsive to the study, the study population, the individual research participant and the research context. Effectively communicating about data sharing with research participants is challenging in practice, highlighting the importance of robust and effective data sharing governance in this context. Broad consent should incorporate effective and efficient explanations of data sharing to promote informed decision-making, without impeding research participants’ understandings of key aspects of the research from which data will be shared. Further work is required to refine both the development of core information about data sharing to be provided to all research participants, and appropriate solutions for context specific-challenges arising when explaining data sharing.
