A significant portion of the Cerrado (Brazilian savanna) has been replaced by major crops such as soybean. This may reveal populations of nematodes with different genetic backgrounds compared to cultivated fields. The objectives of this study were to evaluate the genetic variability and aggressiveness of isolates ofMeloidogynespp., contrasting nematodes from preserved areas of the Cerrado with those originating from cultivated soybean fields. Cluster analysis separated isolates ofMeloidogynespp. and isolates from Cerrado and soybean but did not separate an aggressiveMeloidogyne morocciensisisolate. The aggressiveness of six selected populations ofMeloidogynespp. from Cerrado and soybean against soybean cultivars was evaluated. Results showed that populations ofM. javanicaandM. incognitafrom Cerrado and soybean showed similar aggressiveness. However, forM. morocciensis, the population from soybean was much more aggressive than the one from Cerrado. Aggressiveness is a very intriguing subject that needs special attention for future research in nematology.

Drug side effects have become an important indicator for evaluating the safety of drugs. There are two main factors in the frequent occurrence of drug safety problems; on the one hand, the clinical understanding of drug side effects is insufficient, leading to frequent adverse drug reactions, while on the other hand, due to the long-term period and complexity of clinical trials, side effects of approved drugs on the market cannot be reported in a timely manner. Therefore, many researchers have focused on developing methods to identify drug side effects. In this review, we summarize the methods of identifying drug side effects and common databases in this field. We classified methods of identifying side effects into four categories: biological experimental, machine learning, text mining and network methods. We point out the key points of each kind of method. In addition, we also explain the advantages and disadvantages of each method. Finally, we propose future research directions.

This research analyzed the online reputation of Marbella as a tourist destination and the profiles of the reviewers according to sociodemographic characteristics. A correlational, quantitative research technique was used in this study based on the manual extraction of more than 4000 reviews generated on TripAdvisor. The data used in this study were collected from the TripAdvisor website, taking, as a sample, tourists who had visited the city in the last three years. Ratings that did not provide full data on the variables were excluded. The findings show that Marbella is considered a luxury shopping destination. The preliminary conclusions allow us to generalize about the sociodemographic profile of its tourists. The findings of the study will provide valuable information for Marbella’s Destination Management Organization (DMO). On the one hand, this study highlights the importance of ranking the attractions of the city to create better communication strategies and enhance the appeal of those attractions that receive the best ratings, establishing the true vocation of Marbella as a tourist destination. On the other hand, it provides information on what tourists perceive to be negative elements, allowing the administration to create an improvement plan. The novelty of this research paper is that it delves into Marbella’s online reputation through an analysis of specific attractions’ ratings. Areas that require further attention in future research have been highlighted, along with specific advice on each attraction that contributes to the tourist offerings of the city.

Social Entrepreneurship (SE) describes a new entrepreneurial form combining the generation of financial and social value. In recent years, research interest in SE increased in various disciplines with a particular focus on the characteristics of social enterprises. Whereas a clear-cut definition of SE is yet to be found, there is evidence that culture and economy affect and shape features of SE activity. In addition, sector-dependent differences are supposed. Building on Institutional Theory and employing a mixed qualitative and quantitative approach, this study sheds light on the existence of international and inter-sector differences by examining 161 UK and Indian social enterprises. A content analysis and analyses of variance were employed and yielded similarities as well as several significant differences on an international and inter-sector level, e.g., regarding innovativeness and the generation of revenue. The current study contributes to a more nuanced picture of the SE landscape by comparing social enterprise characteristics in a developed and a developing country on the one hand and different sectors on the other hand. Furthermore, I highlight the benefits of jointly applying qualitative and quantitative methodologies. Future research should pay more attention to the innate heterogeneity among social enterprises and further consolidate and extend these findings.

How cooperatives generate and absorb social capital has attracted a great deal of attention due to the fact that they are collective organizations owned and democratically managed by their members, and, accordingly, are argued to be closely linked to the nature and dynamics of social capital. However, the extant literature and knowledge on the relationship between cooperatives and social capital remain unstructured and fragmented. This paper aims to provide a narrative literature review that integrates both sides of the relationship between cooperatives and social capital. On the one hand, one side involves how cooperatives create internal social capital and spread it in their immediate environment, and, on the other hand, it involves how the presence of social capital promotes the creation and development of cooperatives. In addition, our theoretical framework integrates the dark side of social capital, that is, how the lack of trust, reciprocal relationships, transparency, and other social capital components can lead to failure of the cooperative. On the basis of this review, we define a research agenda that synthesizes key trends and promising research avenues for further advancement of theoretical and empirical insights about the relationship between cooperatives and social capital, placing particular emphasis on rural and agricultural cooperatives.

Confucian mysticism is a subfield in academic areas of study including Chinese thought, Chinese religions, Confucian studies, and comparative mysticism. Important topics examined in this subfield include, first, a view of the human self that is fundamentally relational, both in an interpersonal sense and because Confucians presuppose various correlations and an integration between, on the one hand, the matter–energy, capacities, processes, and activities comprising the self and, on the other, the elements, forces, patterns, and processes of the world it inhabits. One paradigmatic way Confucians conceptualize the interrelation between the self and the cosmos is their idea and ideal of the “unity of Heaven and humanity.” The Confucian mystical self, provided failings such as unbalanced emotions, selfish desires, and self-centeredness are effectively curtailed, contributes vitally to, because of its profound reverence for life, the generative and life-sustaining process of change that pervades and animates the cosmos. Second, practitioners use various techniques of religious praxis in combination to form multifaceted training regimens aimed at self-cultivation and self-transformation. Examples include a form of meditation called “quiet-sitting,” rituals, textual study, “investigating things,” self-examination and self-monitoring, filial piety, and “reverent attentiveness.” Third, training in these practices can achieve the different mystical aims, experiences, and transformations they seek, all of which relate to the overarching ideal of the unity of Heaven and humanity. These objectives, broadly speaking, include self-understanding, accurately grasping the “principles” of things and affairs, effortless moral virtuosity, “forming one body with all things” (and other types of Confucian mystical union), and exemplifying “sincerity.” Accomplishing them collapses the conventional divide separating several specious dichotomies, such as thought and action, self and other, humankind and nature, internal and external, the subjective and the objective, and moral ought and is. Fourth, the influence that precedent and tradition exert in Confucianism has prompted scholars to devote attention both to notable continuities and to intriguing innovations in comparing ancient mystical ideas, practices, experiences, and aims to later expressions and elaborations of them. At present, much of the scholarship on Confucian mysticism contributes to efforts attempting to provide rich and nuanced analyses of the tradition’s core doctrines, practices, experiences, and ethical and religious aims, by viewing these subjects through the lens of Confucianism’s mystical and spiritual dimensions. Less scholarly attention has been devoted to identifying and explicating the possible contributions that studying Confucian mysticism can make to the scholarship on theories of mysticism and comparative mysticism. Scholars of mysticism have not yet availed themselves of the wealth of data, the possible additional perspectives on contested issues, and the new trajectories for future research that Confucianism offers to these fields. Also, few studies employ the definitions, categories, and theories that have been developed in the contemporary study of mysticism as a methodology for studying Confucian mysticism.

Research on planning, method choice, and method substitution in adolescents’ suicide attempts is limited. We conducted in-depth interviews with 20 adolescents following their suicide attempt to learn the extent to which the attempt was planned, why they used the method they did, and whether they would have substituted another method if the one they used had been unavailable. Applied Thematic Analysis was used to identify codes and develop themes. Attempts were largely unplanned, and planned attempts were often haphazard, as urgency to escape immediate pain was a main impetus for the attempt. Method choice was driven by easy access. Half of participants said they would not have attempted suicide if the method they used were inaccessible, but 7 of 20 said they would have, and 3 were unsure. Not all suicide attempts would be prevented by blocking access to methods that adolescent attempters would otherwise use. To understand whether restricting access to low-lethality methods could harm some attempters, future research should examine in-the-moment method substitution.

Deep learning has been used in computer vision to accomplish many tasks that were previously considered too complex or resource-intensive to be feasible. One remarkable application is the creation of deepfakes. Deepfake images change or manipulate a person’s face to give a different expression or identity by using generative models. Deepfakes applied to videos can change the facial expressions in a manner to associate a different speech with a person than the one originally given. Deepfake videos pose a serious threat to legal, political, and social systems as they can destroy the integrity of a person. Research solutions are being designed for the detection of such deepfake content to preserve privacy and combat fake news. This study details the existing deepfake video creation techniques and provides an overview of the deepfake datasets that are publicly available. More importantly, we provide an overview of the deepfake detection methods, along with a discussion on the issues, challenges, and future research directions. The study aims to present an all-inclusive overview of deepfakes by providing insights into the deepfake creation techniques and the latest detection methods, facilitating the development of a robust and effective deepfake detection solution.

A survey of the field of control for flexible multi-link robots is presented. This research area has drawn great attention during the last two decades, and seems to be somewhat less “attractive” now, due to the many satisfactory results already obtained, but also because of the complex nature of the remaining open problems. Thus it seems that the time has come to try to deliver a sort of “state of the art” on this subject, although an exhaustive one is out of scope here, because of the great amount of publications. Instead, we survey the most salient progresses – in our opinion – approximately during the last decade, that are representative of the essential different ideas in the field. We proceed along with the exposition of material coming from about 119 included references. We do not pretend to deeply present each of the methods quoted hereafter; however, our goal is to briefly introduce most of the existing methods and to refer the interested reader to more detailed presentations for each scheme. To begin with, a now well-established classification of the flexible arms control goals is given. It is followed by a presentation of different control strategies, indicating in each case whether the approach deals with the one-link case, which can be successfully treated via linear models, or with the multi-link case which necessitates nonlinear, more complex, models. Some possible issues for future research are given in conclusion.
