Various phenomena such as halo effects, spontaneous trait inferences, and evaluative conditioning have in common that assumptions about object features (e.g., whether a person is intelligent or likeable) are influenced by other object features (e.g., whether that person is attractive or co-occurs with other liked persons). Surprisingly, these phenomena have rarely been related to each other, most likely because different phenomena are described using different terms. To overcome this barrier, we put forward a conceptual framework that can be used to describe a wide range of these phenomena. After introducing the four core concepts of the framework, we illustrate how it can be applied to various phenomena. Doing so helps to reveal similarities and differences between those phenomena, thus improving communication and promoting interactions between different areas of research. Finally, we illustrate the generative power of the framework by discussing some of the new research questions that it highlights.

<p>Several guidelines have been developed that describe methods for analysing riverine macroplastic flows. No single method has emerged as the standard approach for sampling plastic waste in rivers. This reflects the difficulty in establishing a global ‘one size fits all’ approach for river systems: there is significant variability in river morphology, hydrology, and geomorphology across the world and these differences necessitate adaptations of existing methods or the development of new approaches to assess macroplastic flows. In addition, there is a wide range of different potential objectives underpinning the monitoring of riverine macroplastic contamination, including assessments of plastic export, sources, transport, or accumulation. These generate different research questions, which require different solutions, and may necessitate the collection of data in different forms.</p><p>Nevertheless, there is an international demand for generating monitoring datasets that are comparable and can be used to create a holistic picture of macroplastic contamination across the globe. For the reasons listed above, harmonisation – through thorough method validation and quality assurance and control (QA/QC) – is likely to be more important than standardisation in this context. Additionally, in some cases there remains a disconnect between the types of data that are produced in monitoring activities and those which are desired by potential end users of the data. It is valuable, therefore, to increase the communicability of datasets and establish a common language for riverine macroplastic contamination. This study undertakes a critical review of existing methodologies for assessing macroplastic flows in river systems and identifies: i) what component of the macroplastic load is measured by each technique; ii) how can these methods be validated; iii) what QA/QC procedures could be implemented to increase the quality, robustness, and harmonisation of monitoring outputs; and iv) how can outputs be tailored to different uses of monitoring data.</p>

The paper reflects the specificity of the fundamental ideas of the artistic world of M. G. Atamanov, which includes a wide range of literary facts from the content level of the text of the works to their poetics. A particularly important role in the works of M. G. Atamanov is played by cross-cutting themes and images that reflect the author's individual style and his idea of national-ethnic identity. The subject of the research is the book of essays “Mon - Udmurt. Maly mynym vös’?” (“I am Udmurt. Why does it hurt?”), which most vividly reflected the main spiritual and artistic searches of M. G. Atamanov, associated with his ideas about the Udmurt people. The main motives and plots of the works included in the book under consideration are accumulated around the concept of “Udmurtness”. The comprehension of “Udmurtness” is modeled in his essays through specific leit themes: native language, Udmurt people, national culture, mentality, geographic and topographic features of the Udmurt people’ places of residence, the Orthodox idea. The “Udmurt theme” is recognized and comprehended by the writer through the prism of national identity.

This study was carried out to determine the modern office technology competencies expected of office technology and management (OTM) graduate workers by supervisors in Delta State. The study was guided by two research questions and two hypotheses tested at 0.05 level of significance. The respondents consisted of 142 supervisors, made up of 74 heads of department and directors of government establishments, and 68 managers and directors of private establishments in the study area. Descriptive survey research design was used to conduct the study and 28 – items questionnaire were used to collect data from respondents. The instrument was validated by three experts and had a Cronbach Alpha reliability coefficient of 0.77. Means with standard deviations were used to answer the research questions, while t-test was used to test the null hypotheses. The extent of supervisor‟s expectations of information processing competencies did not differ significantly based on the mean ratings of male and female supervisors of OTM graduates in government and private establishments. The findings also revealed that supervisors expect much information processing and communication competencies from the OTM graduate workers. Based on the findings and the implications, it was recommended among others that, curriculum planners, business and OTM education lecturers should ensure that the competencies required for modern office technologies are entrenched and taught in the institutions to prepare the OTM graduates for the world of work.

Neglected Diseases (NDs) affect million of people, especially the poorest population around the world. Several efforts to an effective treatment have proved insufficient at the moment. In this context, triazole derivatives have shown great relevance in medicinal chemistry due to a wide range of biological activities. This review aims to describe some of the most relevant and recent research focused on 1,2,3- and 1,2,4-triazolebased molecules targeting four expressive NDs: Chagas disease, Malaria, Tuberculosis and Leishmaniasis.

UNSTRUCTURED Billions of people in the world own a smartphone. It is a low-cost, portable computing device with countless features, among which applications stand out, which are programs or software developed to meet a specific goal. A wide range of applications available ranging from entertainment and personal organization to work and education is available currently. It is a vast and profitable market. Health applications have been a means of intervention for different areas, including chronic diseases, epidemics, and health emergencies. A recently published paper in the journal with the highest impact factor in Digital Health (“Journal of Medical Internet Research”) proposes a classification of health applications. This study performs a critical analysis of this organization and presents other sort criteria. This paper also presents and analyzes the “Meu Info Saúde” (“My Health Info”) app – a pioneering government initiative focused on primary care launched by the Oswaldo Cruz Foundation. The application classification proposal that will be presented builds on the intervention strategies in the health-disease process, namely: “Health Promotion”, “Disease Prevention” and “Care, Treatment and Rehabilitation”, as defined by official documents such as the World Health Organization and the Centers for Disease Control and Prevention. Most applications present in the sample are of private and foreign origin, free to download, but with a display of ads or the sale of products and services. The sampled applications were classified as “Health Promotion”, and some applications have also been categorized as “Disease Prevention” or “Care, Treatment or Rehabilitation” because they have multiple functionalities. The applications identified as “Health Promotion” focused only on individuals’ lifestyle and their increased autonomy and self-care management capacity. From this perspective, the apps analyzed in this paper differ from the “Meu Info-Saúde” application developed at Fiocruz.

This is a book about wisdom. It is an inquiry into the beginnings of a particular way of thinking about life in the world. Seen in terms of wisdom, the world is not a meaningless array of disconnected things but something that is experienced as an ordered reality. This holistic way of understanding life in the world characterized pursuits of wisdom in a two-sided classical and biblical tradition that exercised a profound influence on Western culture. This book examines the development of that tradition in a wide range of texts from Homer to Plato and in the writings of early Jewish and Christian authors.

Mythographies were books that collected, explained, and interpreted myth-related material. Extremely popular during the Renaissance, these works appealed to a wide range of readers. While the European mythographies of the sixteenth century have been utilized by scholars, the short, early English mythographies, written from 1577 to 1647, have puzzled critics. The first generation of English mythographers did not, as has been suggested, try to compete with their Italian predecessors. Instead, they made mythographies into rhetorical instruments designed to intervene in topical debates outside the world of classical learning. Because English mythographers brought mythology to bear on a variety of contemporary issues, they unfold a lively and historically well-defined picture of the roles myth was made to play in early modern England. Exploring these mythographies can contribute to previous insights into myth in the Renaissance offered by studies of iconography, literary history, allegory, and myth theory.
