This is a work for the general public, authored by an archaeologist and director of a nautical museum. The potential tension this might entail is paralleled by the book’s shifting focus, between popular conceptions of the Vikings as evident in the commercial and cultural spheres, and historical ship-building and sea-faring.

The chapter surveys post-First World War Littlehampton, a coastal town where tourism and hospitality had overtaken maritime trade, but where coastal shipping and ship-building remained important industries. The libel case unfolded in the Beach Town district, where Littlehampton’s hotels and apartment houses were concentrated. Many of the tradesmen, small businesswomen, labourers, and domestics who serviced the tourism and hospitality industry lived in the neighbourhood. Working from the evidence George Nicholls gathered, census records, and documents in the Littlehampton Museum, the chapter provides an anatomy of the neighbourhood and then examines the families at the centre of the dispute, their economic and social position, and relationships within the household, which were often marked by violence.

Abstract We develop a field experiment that assesses whether advertising can serve as a signal that enhances consumers’ evaluations of advertised goods. We implement the experiment on a mobile search platform that provides listings and reviews for an archetypal experience good, restaurants. In collaboration with the platform, we randomize about 200,000 users in 13 Asian cities into exposure of ads for about 600+ local restaurants. Within the exposure group, we randomly vary the disclosure to the consumer of whether a restaurant’s listing is a paid-ad. This enables isolating the effect on outcomes of a user knowing that a listing is sponsored—a pure signalling effect. We find that this disclosure increases calls to the restaurant by 77%, holding fixed all other attributes of the ad. The disclosure effect is higher when the consumer uses the platform away from his typical city of search, when the uncertainty about restaurant quality is larger, and for restaurants that have received fewer ratings in the past. On the supply side, newer, higher rated and more popular restaurants are found to advertise more on the platform; and ratings of those that advertised during the experiment are found to be higher two years later. Taken together, we interpret these results as consistent with a signalling equilibrium in which ads serve as implicit signals that enhance the appeal of the advertised restaurants to consumers. Both consumers and advertisers seem to benefit from the signalling. Consumers shift choices towards restaurants that are better rated (at baseline) in the disclosure group compared to the no disclosure group, and advertisers gain from the improved outcomes induced by disclosure.

Previous studies have demonstrated that organochlorine pesticide (OCP) exposure has a negative impact on the neurological function of infants. Only a few reports have investigated the thyroid and growth hormones and their relationship to neurodevelopment after human exposure to OCPs, especially in the case of infants. Our goal was to determine whether breastmilk OCP residues were associated with negative impacts and/or alterations in the neurodevelopment of infants among specific southern Taiwanese mother–breastfed infant pairs. Our subjects (n = 55 pairs) were recruited from southern Taiwan between 2007 and 2010. The thyroid and growth hormone levels in the cord blood samples collected after childbirth were determined. The breastmilk was gathered within one month after childbirth for the determination of OCP levels using a high-resolution gas chromatograph with mass spectrometry, and the neurodevelopment of 10–12-month-old infants was examined using the Bayley Scales of Infant and Toddler Development®, Third Edition (Bayley-III). It was observed that 4,4′-dichlorodiphenyl-dichloroethylene (4,4′-DDE) (mean = 10.3 ng/g lipid) was the most predominant OCP compound in the breastmilk samples. At higher concentrations (>75th percentile), specific OCPs were associated with significantly lower levels of thyroid and growth hormones than at lower concentrations (<75th percentile). Significantly higher odds ratios (ORs) were observed for binary cognitive (OR = 8.09, p = 0.025 for 4,4′-DDT), language (OR = 11.9, p = 0.013 for 4,4′-DDT) and social–emotional (OR = 6.06, p = 0.01 for trans-CHL) composite scores for specific OCPs belonging to the lower exposure group as compared to the higher OCP exposure group. The five domain Bayley-III infant neurodevelopment outcomes were negatively associated with specific OCPs in the breast milk samples based on the redundancy analysis (RDA) test. Bayley-III scales, which include cognitive, language, motor, social-emotional, and adaptive behavior scales, could be predicted by 4,4′-DDT, endrin, endosulfan I, heptachlor, or heptachlor epoxide using multivariate linear regression models with adjustment for maternal age, pre-pregnant BMI, parity, and infant gender. In conclusion, although our study showed that postnatal exposure to breast milk OCPs may be associated with infant neurodevelopmental outcomes and that prenatal exposure, if extrapolated from breastmilk levels, is associated with changes in thyroid and growth hormones that may have effects on neurodevelopment, these associations are only suggestive; thus, further studies are recommended for confirmation.

This study aimed to measure lead (Pb) and cadmium (Cd) exposure levels in residents living near a zinc (Zn) smelter in Seokpo-myeon, Bonghwa-gun, South Korea, and identify factors affecting exposure. Residents aged ≥20 years living within 3 km and ≥30 km away from the smelter were classified as the exposure group (n = 549), and the control group (n = 265), respectively. Data were obtained through a questionnaire survey. Blood Pb levels in the exposure group (4.19 µg/dL) were higher than in the control group (2.70 µg/dL). The exposure group (1.32 µg/L) also had higher urinary Cd concentrations than the control group (0.80 µg/L). Male sex, older age, previous work at the smelter, smoking, and proximity to the smelter were associated with higher blood Pb levels on multivariate analysis; urinary Cd concentration was significantly higher in women, those who were older, those with experience of working in a Zn smelter or mine, those with proximity to the Zn smelter, and those who consumed locally grown vegetables. In conclusion, Zn smelters are major source of Pb and Cd pollution and require ongoing public health management to prevent potential adverse health effects.

The present study examined the efficacy of eye movement desensitization and reprocessing (EMDR) in the treatment of a specific phobia. Twenty-four spider phobic subjects were randomly assigned to either (1) an EMDR group (n=8), (2) an imaginal exposure group (n=8), or (3) a control group (n=8). Both the EMDR and the imaginal exposure group underwent a one-hour treatment. The control group initially received no treatment, and waited for one hour. Next, all groups received exposure in vivo. Treatment outcome was evaluated with a standardized Behavioural Avoidance Test (BAT). No evidence was found for EMDR being more effective than imaginal exposure or waiting list control. In fact, only exposure in vivo therapy resulted in significant improvement on the BAT.
