ABSTRACTSpiders are able to arouse strong emotional reactions in humans. While spider bites are statistically rare events, our perception is skewed towards the potential harm spiders can cause to humans. We examined the human dimension of spiders through the lens of traditional media, by analysing more than 300 spider-related news published online in Italian newspapers between 2010 and 2020. We observed a recent, exponential increase in the frequency of the news, particularly those focused on medically important spiders – the Mediterranean black widow (Latrodectus tredecimguttatus) and the Mediterranean recluse (Loxosceles refescens). The news quality was generally poor: 70% contained different types of error, 32% were exaggerated, and in virtually none was an expert consulted. Overstated news referring to spider bites were significantly more shared on social media, thus contributing to frame a distorted perception of the risk associated with a spider bite and possibly reducing general public tolerance of spiders.

Black widow spider bites are uncommon in South Africa, but it is important for clinicians to be aware of the clinical presentation in order to initiate appropriate treatment. This case highlights the presentation and management of a middle-aged gentleman who presented to the Chris Hani Baragwanath hospital following a spider bite. The bite was later confirmed to be that of a black widow spider. The patient presented with the typical symptoms of latrodectism – autonomic dysfunction, muscle rigidity and cramps – and was managed symptomatically with a favourable outcome.

Widow Spider

We report a patient with antineutrophilic cytoplasmic antibody (ANCA) vasculitis that was preceded by witnessed black widow spider bites. The patient initially presented with a diffuse painful skin rash that developed after a few hours post bite. He was treated initially with topical ointment for the suspected bite. However, subsequently a few days later the patient returned to the hospital with similar, but more progressive rash with haemoptysis and acute hypoxic respiratory failure requiring supplemental oxygen. Immunology work up showed elevated titre of peri-nuclear ANCA. Bronchoscopy revealed diffuse alveolar haemorrhage. The patient was treated successfully with methylprednisolone and rituximab.

Spider Bite

Spider bites can cause local tissue damage as well as life-threatening complications. This is a case report of a female with no history of lower extremity vascular disease who presented with a spider bite on the dorsum of her foot. She developed progressive necrosis and eventually suffered limb loss despite attempts at revascularization.

Main Effects

This study explores the effects of traditional media and social media on different types of knowledge about COVID-19. We also explore how surveillance motivation moderates the relationship between media use and different types of knowledge. Based on cross-national data from Singapore and the United States, we find that news seeking via social media is negatively related to factual knowledge and positively related to subjective knowledge and knowledge miscalibration. News seeking via traditional media is not significantly related to factual knowledge. Although the main effects are highly consistent across the two countries, we find some different interaction patterns across these countries.

The Way

This chapter focuses on electoral ergonomics, defined as the interface between every aspect of electoral organization and the psychology of the voters. It argues that every small detail in the organization of the vote (electoral ergonomics) matters not only mechanically, but also because of the way it may trigger different psychological mechanisms and emotional reactions, and that as a result, the ergonomic interface will have different effects on different types of voter, such as ‘referees’ or ‘supporters’. Indeed, electoral ergonomics affects the way citizens experience the vote, their attitudes, their likeliness to vote in elections, and their actual electoral choice. The chapter then unpacks the theoretical and empirical logic behind the influence of electoral ergonomics, both in general and through specific case studies. These case studies include the impact of the use of remote voting on electoral experience in the general population, its influence on the electoral choice of young voters, and the effect of ballot-paper design (including paper vs electronic ballots) on the electoral experience.

Social Media Platforms

Social media platforms such as Twitter are extensively used for expressing and exchanging thoughts, opinions, ideas, and feelings, i.e., reactions concerning a topic or an event. Factual information about an event to which people are reacting can be obtained from different types of (geo-)sensors, official authorities, or the public press. However, these sources hardly reveal the emotional or attitudinal impact of events on people, which is, for example, reflected in their reactions on social media. Two approaches that utilize emojis are proposed to obtain the sentiment and emotions contained in social media reactions. Subsequently, these two approaches, along with visualizations that focus on space, time, and topic, are applied to Twitter reactions in the example case of Brexit.

The backlash compensation has a great effect on the synthetical precision of CNC machine tool. Here, the measuring and backlash compensating technologies were investigated for high-speed CNC machine tool. Following, the backlash compensation of the synthetical geometric error of the interpolatimg movement and the evaluation system of position accuracy were proposed during CNC machine tool processing. The results indicate that the basic feature of error is established and provides a basis for putting forward the new error measurement method under the essential measuring condition. It also could be applied for different types of error compensation, shows that the backlash of the milling processing could be well compensated.
