Science has always been evaluated and will always be. The reasons justifying evaluations and the methods used to carry them have varied over time in relation to the many transformations of the sciences over the last fifty years. The uses of bibliometric methods are not limited to ‘evaluations’ of scientists and their institutions as they also provide a unique way to map global trends. One cannot stop evaluating science, but one can use the right tools at the right scale (individuals, institutions, countries) to better understand the dynamic of scientific change.

The business can be influenced by the location of the location and the type of business that was built in the specified location and can develop over time but it is not impossible for bankruptcy to occur because the type of business is not in the right location and promising due to factors that do not support at that location, include that area where the population is not too dense and the land is not that large. For this reason, the authors conduct research on strategic locations to open a particular type of business depending on the location found by the Naive Bayes method. Where the method is used to predict accurately from the many locations that have been researched after that it is determined which is more appropriate area.

Abstract Background Previous research in resting-state functional magnetic resonance imaging (rs-fMRI) has shown a mixed pattern of disrupted thalamocortical connectivity in psychosis. The clinical meaning of these findings and their stability over time remains unclear. We aimed to study thalamocortical connectivity longitudinally over a 1-year period in participants with recent-onset psychosis. Methods To this purpose, 129 individuals with recent-onset psychosis and 87 controls were clinically evaluated and scanned using rs-fMRI. Among them, 43 patients and 40 controls were re-scanned and re-evaluated 12 months later. Functional connectivity between the thalamus and the rest of the brain was calculated using a seed to voxel approach, and then compared between groups and correlated with clinical features cross-sectionally and longitudinally. Results At baseline, participants with recent-onset psychosis showed increased connectivity (compared to controls) between the thalamus and somatosensory and temporal regions (k = 653, T = 5.712), as well as decreased connectivity between the thalamus and left cerebellum and right prefrontal cortex (PFC; k = 201, T = −4.700). Longitudinal analyses revealed increased connectivity over time in recent-onset psychosis (relative to controls) in the right middle frontal gyrus. Conclusions Our results support the concept of abnormal thalamic connectivity as a core feature in psychosis. In agreement with a non-degenerative model of illness in which functional changes occur early in development and do not deteriorate over time, no evidence of progressive deterioration of connectivity during early psychosis was observed. Indeed, regionally increased connectivity between thalamus and PFC was observed.

To a free people, the very word “censorship” always has been distasteful. In its theory, it runs counter to all democratic principles; in practice, it can never be made popular, can never please anyone.Everything the censor does is contrary to all that we have been taught to believe is right and proper. The Post Office Department, for example, has two proud mottoes: “The mail must go through,” and “The privacy of the mail must be protected at all hazards.” But censorship stops the mail, it invades the privacy of the mail, it disposes of the mail as may seem best. The same thing holds true in the publishing business. Censorship limits the lively competition and free enterprise of reporters. It relegates many a scoop to the waste basket. It wields a blue pencil—both theoretical and actual—on news stories, magazine articles, advertisements, and photographs. Censorship also enters the radio industry, where it may edit scripts and in some cases stop entire programs.Yet even the most vociferous critics of the principle of censorship agree that in war-time some form and amount of censorship is a necessity. It then becomes not merely a curtailment of individual liberty, but a matter of national security. It is one of the many restrictions that must be imposed on people fighting for the right to throw off those restrictions when peace returns.

Purpose: By taking advantage of 18F-FDG PET imaging and tissue nuclear magnetic resonance (NMR) metabolomics, we examined the dynamic metabolic alterations induced by liver irradiation in a mouse model for hepatocellular carcinoma (HCC). Methods: After orthotopic implantation with the mouse liver cancer BNL cells in the right hepatic lobe, animals were divided into two experimental groups. The first received irradiation (RT) at 15 Gy, while the second (no-RT) did not. Intergroup comparisons over time were performed, in terms of 18F-FDG PET findings, NMR metabolomics results, and the expression of genes involved in inflammation and glucose metabolism. Results: As of day one post-irradiation, mice in the RT group showed an increased 18F-FDG uptake in the right liver parenchyma compared with the no-RT group. However, the difference reached statistical significance only on the third post-irradiation day. NMR metabolomics revealed that glucose concentrations peaked on day one post-irradiation both, in the right and left lobes—the latter reflecting a bystander effect. Increased pyruvate and glutamate levels were also evident in the right liver on the third post-irradiation day. The expression levels of the glucose-6-phosphatase (G6PC) and fructose-1, 6-bisphosphatase 1 (FBP1) genes were down-regulated on the first and third post-irradiation days, respectively. Therefore, liver irradiation was associated with a metabolic shift from an impaired gluconeogenesis to an enhanced glycolysis from the first to the third post-irradiation day. Conclusion: Radiation-induced metabolic alterations in the liver parenchyma occur as early as the first post-irradiation day and show dynamic changes over time.

History textbooks are less likely to be complete renderings of the truth than a series of stories textbook authors (and the many stakeholders who influence them) consider beneficial. Sam Wineburg describes how the process of writing history textbooks often leads to sanitized and inaccurate versions of history. As an example, he describes how the story of Crispus Attucks and the Boston massacre has evolved over time. The goal of historical study, he explains, is not to cultivate love or hate of the country. Rather, it should provide us with the courage needed to look ourselves unflinching in the face, so that we may understand who we were and who we might aspire to become.

The “go/no-go” decision for a candidate property, i.e., whether or not to actually acquire the site, choose the brand (flag), build and operate the hotel, requires the explicit consideration of the interconnectedness of the many myriad elements affecting the property's potential profits. The many facility design decisions (number and mix of rooms, capacity for F&B operations etc.) as well as other strategic choices (e.g., size of marketing program, level of service aimed for) must recognize the site's competitive features and interactions with the above. Also, the particular design and operational features for a given property will affect its different revenue streams, fixed and variable costs, efficiency and profits. The authors consider developers contemplating acquiring a given site, choosing a brand, building and operating a new hotel. They offer a normative approach for this type of decision which arrives endogenously at possibly attractive options for the brand, design and strategic choices for the site. The final decision as to which option to actually use, if any, should be based on subjecting the above identified scenarios, as well as others, to traditional feasibility analyses where judgment and expert opinion are applied. The authors' implementable approach integrates a “best practices” benchmarking methodology with regression analysis to yield a mathematical programming optimization model. A key advantage of this approach lies in its contrast to conventional approaches for site selection which often ignore the more detailed design and strategic choices. The approach deals explicitly with the complex interfaces between marketing and operations management as the endogenous site and competitive environmental factors interact with the endogenous brand and facility design choices. By identifying attractive options to be further explored (that might otherwise be overlooked), several types of errors are avoided: i) an incorrect “go/no go” decision could be recommended for the site in question; ii) even if the right decision to proceed is made, the forecasted level of annualized profits could be in error, leading to an incorrect priority for the activity; iii) the incorrect brand and facility design choices could be made for the site. Other key advantages of the suggested approach are that 1) various substitution possibilities (between more or less capital, labor, materials etc.) are considered; 2) not only is the best brand and configuration identified, but also a ranking of other brands is available if the “best” brand is not available; 3) the “best practices” at other specific sites (which serve as the basis for the recommendations) are identified, thereby enabling management (possibly through site visits) to isolate the actual cultures, processes and procedures to be transported and emulated at the candidate site. This paper illustrates the approach for two different sites.

In the entry on ‘Fascism’ published in 1932 in the Enciclopedia Italiana, Benito Mussolini made a prediction. There were, he claimed, good reasons to think that the twentieth century would be a century of ‘authority’, the ‘right’: a fascist century (un secolo fascista). However, after 1945 the many attempts by fascists to perpetuate the dreams of the 1930s have come to naught. Whatever impact they have had at a local level, and however profound the delusion that fascists form a world-wide community of like-minded ultranationalists and racists revolutionaries on the brink of ‘breaking through’, as a factor in the shaping of the modern world, their fascism is clearly a spent force. But history is a kaleidoscope of perspectives that dynamically shift as major new developments force us to rewrite the narrative we impose on it. What if we take Mussolini’s secolo to mean not the twentieth century, but the ‘hundred years since the foundation of Fascism’? Then the story we are telling ourselves changes radically.

It is now notorious that the production of inscriptions in the Roman Empire was not constant over time, but rose over the first and second centuries A.D. and fell in the third. Ramsay MacMullen pointed this out more than five years ago, with conclusions more cautionary than explanatory: ‘history is not being written in the right way’, he said, for historians have deduced Rome's decline from evidence that–since it appears only epigraphically–has merely disappeared for its own reasons, or have sought general explanations of decline in theories political, economic, or even demographic in nature, none of which can, in turn, explain the disappearance of epigraphy itself. Why this epigraphic habit rose and fell MacMullen left open to question, although he did postulate control by a ‘sense of audience’. The purpose of this paper is to propose that this ‘sense of audience’ was not generalized or generic, but depended on a belief in the value of romanization, of which (as noted but not explained by MacMullen's article) the epigraphic habit is also a rough indicator. Epitaphs constitute the bulk of all provincial inscriptions and in form and number are (generally speaking) the consequence of a provincial imitation of characteristically Roman practices, an imitation that depended on the belief that Roman legal status and style were important, and that may indeed have ultimately depended, at least in North Africa, on the acquisition or prior possession of that status. Such status-based motivations for erecting an epitaph help to explain not only the chronological distribution of epitaphs but also the differences in the type and distribution of epitaphs in the western and eastern halves of the empire. They will be used here moreover to suggest an explanation for the epigraphic habit as a whole.

AbstractThe “Right to the night sky” outreach project holds astronomy workshops for children and teens deprived of their liberty in juvenile detention centers. It is carried out by an interdisciplinary group of students, graduates, and teachers of Astronomy, Geophysics, Educational Science, Law, Psychology, Social Work, and Social Communication. It’s has been accredited and recognized by the Faculty of Astronomical and Geophysical Sciences, and the National University of La Plata (Argentina) since the year 2014. This work presents the diverse activities developed in the project, the methodologies used, and an analysis of how the project evolved, grew, and expanded over time, continuing what has already been presented by Charalambous et al. (2014) and Haack et al. (2019)

ObjectivesTo identify proponents and opponents of the commercialisation and marketing of e-cigarettes and heated tobacco products (HTPs), identify the arguments used on both sides and compare how the arguments have changed over time, we analysed three policy discussions occurring in 2009, 2018 and 2019.MethodsWe conducted a content analysis of one document and six videos from these discussions, provided on the Brazilian Health Regulatory Agency website, or upon request.ResultsThe arguments most used by tobacco companies were related to claims that the use of e-cigarettes and HTPs is less harmful than conventional tobacco. Unions that support its commercialisation also argued that lifting the ban would prevent smuggling and guarantee their quality. On the other side, universities, medical and anti-tobacco institutions argued that such devices may have health risks, including the risk of inducing cigarette smoking. In 2009, most arguments belonged to the ‘health’ theme, while in 2018 and 2019 economic arguments and those related to morals and ethics were frequently used.ConclusionsThose that supported the commercialisation and marketing of e-cigarettes and HTPs first focused on arguments of harm reduction, while 10 years later the right to access and potential economic consequences also became common. Public health agents and academics must gather evidence to effectively respond to these arguments and discuss these policies, and must prepare themselves to use and respond to arguments related to moral and economic themes.
