We compare travel distance estimation from path integration during walking with path integration from visual flow. For visually simulated self-movement humans typically underestimate travel distance, which can be explained by leaky path integration. The amount of leak, i.e., the underestimation, is determined by the length of the path. For visually simulated movements along curved paths that veer left and right around a central forward direction estimates of the start-to-end distance decrease as the veering, i.e., the path length increases. Leaky path integration for visual travel distance estimation thus takes place along the actually traversed path even when a straight beeline distance is calculated. We studied whether the same leaky path integration occurs during real self-motion when vestibular and proprioceptive cues are available instead of vision. Sixteen subjects walked blindfolded from a starting point to targets 20, 30 or 40 m away, guided by an experimenter. They walked either along a straight line, or along paths that deviated first to the right and then to the left (or vice versa) before they reached the end point. This increased the path length by 5, 10, 20 or 30%. Subjects then gave a verbal estimate of their beeline distance from the starting point. Like in the visually simulated case, distance estimates for the same start-to-end distance of 40 m dropped as the path length increased, consistent with the prediction of the leaky integration model. We conclude that travel distance estimation is similar for visual and for vestibular/proprioceptive cues.

The Relationship

UNSTRUCTURED Over half of Americans report looking up health-related questions on the internet, including questions regarding their own ailments. The internet, in its vastness of information, provides a platform for patients to understand how to seek help and understand their condition. In most cases, this search for knowledge serves as a starting point to gather evidence that leads to a doctor’s appointment. However, in some cases, the person looking for information ends up tangled in an information web that perpetuates anxiety and further searches, without leading to a doctor’s appointment. The Internet can provide helpful and useful information; however, it can also be a tool for self-misdiagnosis. Said person craves the instant gratification the Internet provides when ‘googling’ – something one does not receive when having to wait for a doctor’s appointment or test results. Nevertheless, the Internet gives that instant response we demand in those moments of desperation. Cyberchondria, a term that has entered the medical lexicon in the 21st century after the advent of the internet, refers to the unfounded escalation of people’s concerns about their symptomatology based on search results and literature online. ‘Cyberchondriacs’ experience mistrust of medical experts, compulsion, reassurance seeking, and excessiveness. Their excessive online research about health can also be associated with unnecessary medical expenses, which primarily arise from anxiety, increased psychological distress, and worry. This vicious cycle of searching information and trying to explain current ailments derives into a quest for associating symptoms to diseases and further experiencing the other symptoms of said disease. This psychiatric disorder, known as somatization, was first introduced to the DSM-III in the 1980s. Somatization is a psycho-biological disorder where physical symptoms occur without any palpable organic cause. It is a disorder that has been renamed, discounted, and misdiagnosed from the beginning of the DSMs. Somatization triggers span many mental, emotional, and cultural aspects of human life. Our environment and social experiences can lay the blueprint for disorders to develop over time; an idea that is widely accepted for underlying psychiatric disorders such as depression and anxiety. The research is going in the right direction by exploring brain regions but needs to be expanded on from a sociocultural perspective. In this work, we explore the relationship between somatization disorder and the condition known as cyberchondria. First, we provide a background on each of the disorders, including their history and psychological perspective. Second, we proceed to explain the relationship between the two disorders, followed by a discussion on how this relationship has been studied in the scientific literature. Thirdly, we explain the problem that the relationship between these two disorders creates in society. Lastly, we propose a set of intervention aids and helpful resource prototypes that aim at resolving the problem. The proposed solutions ranged from a site-specific clinic teaching about cyberchondria to a digital design-coded chrome extension available to the public.

Normative Justification

According to David Miller, immigration is not a human right. Conversely, Kieran Oberman makes a case for immigration as a human right. We agree with the latter view, but we show that its starting point is mistaken. Indeed, both Miller and Oberman discuss the right to immigration within the liberal paradigm: it is a right or not depending on the correct balance between the interests of the citizens of a given national state and the interests of the immigrants. Instead, we claim that public justification can underpin immigration as a human right. That said, the public justification of the right to immigration has several counterarguments to rebut. Before we deal with that issue, relying on Jürgen Habermas’s social theory, we examine the legal structures that could support the right to immigration in practice. To be sure, this does not provide the normative justification needed, instead it shows the framework that allows the institutional realization of this right. Then, through a combination of civic and cosmopolitan forms of solidarity, the article discusses the formation of a public sphere, which could provide the justification of the right to immigration.

AbstractIndustry-sponsored medical education is a much disputed issue. So far, there has been no regulatory framework which provides clear and definite rules as to whether and under what circumstances the sponsorship of medical education is acceptable. State regulation does not exist, or confines itself to a very general principle. Professional regulation, even though applied frequently, is rather vague and indefinite, raising the general question as to whether self-regulation is the right approach at all. Certainly, self-regulation by industry cannot and should not replace other regulatory approaches. Ultimately, advertising law in general and the European Directive 2001/83/EC specifically, might be a good starting point in providing legal certainty and ensuring the independence of medical education. Swiss advertising law illustrates how the principles of the European Directive could be implemented clearly and unambiguously.

Locus Classicus

When the topic of severance of a beneficial joint tenancy is discussed, most judges and academics start with the case of Williams v Hensman. The judgment of Sir William Page Wood V-C is the ‘locus classicus’, the ‘starting point for any discussion of the modem law’. One paragraph of Page Wood's judgment is quoted in case after case:‘A joint tenancy may be severed in three ways: in the first place, an act of one of the persons interested operating on his own share may create a severance as to that share. The right of each joint tenant is a right by survivorship only in the event of no severance having taken place of the share which is claimed under the jus accrescendi. Each one is at liberty to dispose of his own interest in such a manner as to sever it from the joint fund - losing, of course, at the same time, his own right of survivorship.

The coronavirus pandemic is a modern social emergency and the biggest global challenge since the Second World War. Since the pandemic began in China at the end of 2019, the disease spread to every landmass except Antarctica. The effect of antiviral drugs on the new corona virus has been tested, but no basic and complete cure has been found, although there are many drugs such as  interleukin-6 inhibitor,  monoclonal antibody and corticosteroid which remarkably reduced mortality of critically ill COVID-19 patients in a major clinical trial. Although not enough experimental data has been released yet, many researchers have hailed the result as a step in the right direction. In this review, a series of the newly chemical derivatives were synthesized and evaluated against human coronavirus. Many derivatives found to be active in inhibiting the cellular infection of human coronavirus which causes the SARS-CoV-2pandemic. This mini- review summarizes the synthesis of these new antiviral derivatives that target coronaviruses and describes general current strategies and models for developing antiviral drugs. The review aims to provide a starting point for medicinal chemists to synthesize necessary and effective drugs against coronaviruses.

I artiklen sættes med afsæt i fjernvandreruten fokus på, hvad det er der gør, at vi i Danmark ikke har samme vandrekultur som i vores nabolande.The Missing LinkA long-distance footpath runs from Kilpisjärvi in northern Finland to Alexandroupolis in Greece. However the track does not cross intact but is interrupted on the island of Funen in Denmark. It is no coincidence that the rupture is in Denmark, nor that it is on Funen. In this article this ‘missing link’ provides the starting point to discuss a walking culture, which in Denmark is notable by its absence.At the beginning of 20th century, thanks to the influence of neighbouring countries, the culture of walking did increasingly make itself felt in Denmark. Longer walks became popular and many Danes embarked on hiking tours, walking for several days and spending the night at special ‘vandrehjem’ (or ‘youth hostels’). Since the Second World War this culture has more or less disappeared, and the question asked here is why?The article is divided in two parts. In the first there is a historical review of the development of the Danish culture of walking from the beginning of 20th century until the late 1930’s. This is followed by a discussion of the circumstances that led to the disappearance of this walking culture, focusing on the long distance footpath. This centres on a jostling for supremacy among sporting factions and on the struggle between various outdoor interests, between different management concerns, and between farmers, the state and local authorities about who should have the right to develop and exploit the landscape in southern Funen area. In this struggle organisations representing outdoor activities have been poorly organized and until now the landscape has primary been developed on the premises of agriculture, industry and urbanism.Today the position and status of outdoor life (friluftsliv) and the culture of hiking are improving. Councils in particular are focusing on health, tourism and attracting new residents´, and there is both a political and a popular will to establish hiking trails. For the long-distance footpath these changes mean that the missing link on Funen now disappears and that the hiking trail across Europe is established.

Quer-se mostrar aqui que a Teologia da Libertação partiu bem, mas, devido à sua ambigüidade epistemológica, acabou se desencaminhando: colocou os pobres em lugar de Cristo. Dessa inversão de fundo resultou um segundo equívoco: instrumentalização da fé “para” a libertação. Erros fatais, por comprometerem os bons frutos desta oportuna teologia. Numa segunda parte, expõe-se a lógica da Conferência de Aparecida, que ajuda aquela teologia a “voltar ao fundamento”: arrancar de Cristo e, a partir daí, resgatar os pobres.Abstract: It is our intention to show here that the Theology of Liberation started off on the right track but, given its epistemological ambiguity, ended up by going astray: it put the poor in the place of Christ. A second mistake resulted from this fundamental inversion: the faith became an instrument “for” liberation. Fatal errors, for they jeopardized the good fruits of this opportune theology. In a second part, we explain the reasoning behind the Aparecida Conference: the need to help that theology to “return to basics”, to have Christ as its starting point and, through this, rescue the poor.

The purpose of this study was to analyze guerrilla gardening’s relationship to urban space and contemporary notions of sustainability. To achieve this two case studies of urban agriculture, one of guerrilla gardening and one of community gardening were developed. Through this comparison, guerrilla gardening was framed as a method of spatial intervention, drawing in notions of spatial justice and the right to the city as initially theorized by Henri Lefebvre. The guerrilla gardening case study focuses on Dig Kingston, a project started by the researcher in June of 2010, and the community gardening case study will use the Oak Street Garden, the longest standing community garden in Kingston. The community gardening case study used content analysis and semi-structured long format interviews with relevant actors. The guerrilla gardening case study consisted primarily of action based research as well as content analysis and semi-structured long format interviews. By contributing to the small, but growing, number of accounts and research on guerrilla gardening this study can be used as a starting point to look into other forms of spatial intervention and how they relate to urban space and social relations. Furthermore, through the discussion of guerrilla gardening in an academic manner more legitimacy and weight will be given to it as a method of urban agriculture and interventionist tactic. On a wider scale, perhaps it could even contribute to answering the question of how we (as a society) can transform our cities and reengage in urban space.

Up to now the cranial cover has not been mentioned among other commonly known reflexogenic zones, and one would think that it really cannot serve as such a zone. However, when trying to solve experimentally the question whether irritation of the cranial cover could cause reactions which by their nature and by virtue of their regularity would have the right to be called reflexes, I soon became convinced that the cranial cover can also be a starting point for obtaining some diagnostically valuable reflexes, which is why these reflexes are described in this article.
