Summary
This chapter aims to explore how intelligence research – both current evidence as well as potential new findings that remain undiscovered – might inform education and public policy. We will first address why studying human intelligence is not only an exciting area of research for basic discovery, but also how knowledge about intelligence might be applicable to education and public policy. We will review selected areas of intelligence related research with potential implications for policy. We will discuss research on intelligence test scores as predictors of school performance and later success and research on features of the most promising policy relevant variables for improving intelligence. Finally, we will conclude with a discussion and explanation for researchers about how influencing policy requires (1) learning from policy researchers and practitioners, who have expertise that we argue complements the strengths of intelligence researchers and (2) effectively communicating those findings to policy researchers and practitioners. We write this chapter primarily from the perspective of researchers who are engaged in intelligence research that might be applied to education and policy discussions.

Background:
Nosocomial outbreaks leading to healthcare worker (HCW) infection and death have been increasingly reported during the coronavirus disease 2019 (COVID-19) pandemic.
Objective:We implemented a strategy to reduce nosocomial acquisition.
Methods:We summarized our experience in implementing a multipronged infection control strategy in the first 300 days (December 31, 2019, to October 25, 2020) of the COVID-19 pandemic under the governance of Hospital Authority in Hong Kong.
Results:Of 5,296 COVID-19 patients, 4,808 (90.8%) were diagnosed in the first pandemic wave (142 cases), second wave (896 cases), and third wave (3,770 cases) in Hong Kong. With the exception of 1 patient who died before admission, all COVID-19 patients were admitted to the public healthcare system for a total of 78,834 COVID-19 patient days. The median length of stay was 13 days (range, 1–128). Of 81,955 HCWs, 38 HCWs (0.05%; 2 doctors and 11 nurses and 25 nonprofessional staff) acquired COVID-19. With the exception of 5 of 38 HCWs (13.2%) infected by HCW-to-HCW transmission in the nonclinical settings, no HCW had documented transmission from COVID-19 patients in the hospitals. The incidence of COVID-19 among HCWs was significantly lower than that of our general population (0.46 per 1,000 HCWs vs 0.71 per 1,000 population; P = .008). The incidence of COVID-19 among professional staff was significantly lower than that of nonprofessional staff (0.30 vs 0.66 per 1,000 full-time equivalent; P = .022).
Conclusions:A hospital-based approach spared our healthcare service from being overloaded. With our multipronged infection control strategy, no nosocomial COVID-19 in was identified among HCWs in the first 300 days of the COVID-19 pandemic in Hong Kong.

We have previously shown that higher intake of cruciferous vegetables is inversely associated with carotid artery intima-media thickness. To further test the hypothesis that an increased consumption of cruciferous vegetables is associated with reduced indicators of structural vascular disease in other areas of the vascular tree, we aimed to investigate the cross-sectional association between cruciferous vegetable intake and extensive calcification in the abdominal aorta. Dietary intake was assessed, using a FFQ, in 684 older women from the Calcium Intake Fracture Outcome Study. Cruciferous vegetables included cabbage, Brussels sprouts, cauliflower and broccoli. Abdominal aortic calcification (AAC) was scored using the Kauppila AAC24 scale on dual-energy X-ray absorptiometry lateral spine images and was categorised as ‘not extensive’ (0–5) or ‘extensive’ (≥6). Mean age was 74·9 (sd 2·6) years, median cruciferous vegetable intake was 28·2 (interquartile range 15·0–44·7) g/d and 128/684 (18·7 %) women had extensive AAC scores. Those with higher intakes of cruciferous vegetables (>44·6 g/d) were associated with a 46 % lower odds of having extensive AAC in comparison with those with lower intakes (<15·0 g/d) after adjustment for lifestyle, dietary and CVD risk factors (ORQ4 v. Q1 0·54, 95 % CI 0·30, 0·97, P = 0·036). Total vegetable intake and each of the other vegetable types were not related to extensive AAC (P > 0·05 for all). This study strengthens the hypothesis that higher intake of cruciferous vegetables may protect against vascular calcification.

Background:
The role of severe respiratory coronavirus virus 2 (SARS-CoV-2)–laden aerosols in the transmission of coronavirus disease 2019 (COVID-19) remains uncertain. Discordant findings of SARS-CoV-2 RNA in air samples were noted in early reports.
Methods:Sampling of air close to 6 asymptomatic and symptomatic COVID-19 patients with and without surgical masks was performed with sampling devices using sterile gelatin filters. Frequently touched environmental surfaces near 21 patients were swabbed before daily environmental disinfection. The correlation between the viral loads of patients’ clinical samples and environmental samples was analyzed.
Results:All air samples were negative for SARS-CoV-2 RNA in the 6 patients singly isolated inside airborne infection isolation rooms (AIIRs) with 12 air changes per hour. Of 377 environmental samples near 21 patients, 19 (5.0%) were positive by reverse-transcription polymerase chain reaction (RT-PCR) assay, with a median viral load of 9.2 × 102 copies/mL (range, 1.1 × 102 to 9.4 × 104 copies/mL). The contamination rate was highest on patients’ mobile phones (6 of 77, 7.8%), followed by bed rails (4 of 74, 5.4%) and toilet door handles (4 of 76, 5.3%). We detected a significant correlation between viral load ranges in clinical samples and positivity rate of environmental samples (P < .001).
Conclusion:SARS-CoV-2 RNA was not detectable by air samplers, which suggests that the airborne route is not the predominant mode of transmission of SARS-CoV-2. Wearing a surgical mask, appropriate hand hygiene, and thorough environmental disinfection are sufficient infection control measures for COVID-19 patients isolated singly in AIIRs. However, this conclusion may not apply during aerosol-generating procedures or in cohort wards with large numbers of COVID-19 patients.

Summary
The ways in which women and men differ in intelligence and specific cognitive abilities are among psychology’s most heated controversies. Massive amounts of data show that although there are some on average differences in specific cognitive abilities, there is considerable overlap in the male and female distributions. There are no sex differences in general intelligence – standardized IQ tests were written to show no differences, and separate assessments that were not written with this criterion show no differences in general intelligence. There are more males in some categories of mental disability that are genetically linked, but there are no genetic explanations for differential achievement at the high end of the distributions. Average between-sex differences on specific cognitive abilities – notably reading and writing (female advantage) and some mathematical and visuospatial abilities (male advantage) – often show considerable cross-cultural variation in effect size. Additionally, there have been changes over time so that any conclusions about this controversial topic that we make today may need to be revised in the future.

Seasonal influenza virus epidemics have a major impact on healthcare systems. Data on population susceptibility to emerging influenza virus strains during the interepidemic period can guide planning for resource allocation of an upcoming influenza season. This study sought to assess the population susceptibility to representative emerging influenza virus strains collected during the interepidemic period. The microneutralisation antibody titers (MN titers) of a human serum panel against representative emerging influenza strains collected during the interepidemic period before the 2018/2019 winter influenza season (H1N1-inter and H3N2-inter) were compared with those against influenza strains representative of previous epidemics (H1N1-pre and H3N2-pre). A multifaceted approach, incorporating both genetic and antigenic data, was used in selecting these representative influenza virus strains for the MN assay. A significantly higher proportion of individuals had a ⩾four-fold reduction in MN titers between H1N1-inter and H1N1-pre than that between H3N2-inter and H3N2-pre (28.5% (127/445) vs. 4.9% (22/445), P < 0.001). The geometric mean titer (GMT) of H1N1-inter was significantly lower than that of H1N1-pre (381 (95% CI 339–428) vs. 713 (95% CI 641–792), P < 0.001), while there was no significant difference in the GMT between H3N2-inter and H3N2-pre. Since A(H1N1) predominated the 2018–2019 winter influenza epidemic, our results corroborated the epidemic subtype.

Near-equiatomic porous nickel-titanium shape memory alloys (NiTi SMAs) are becoming one of the most promising biomaterials in bone implants because of their unique advantages over currently used biomaterials. For example, they have good mechanical properties and lower Young�s modulus relative to dense NiTi, Ti, and Ti-based alloys. Porous NiTi SMAs are relatively easy to machine compared to porous ceramics such as hydroxyapatite and calcium phosphate that tend to exhibit brittle failure. The porous structure with interconnecting open pores can also allow tissue in-growth and favors bone osseointegration. In addition, porous NiTi alloys remain exhibiting good shape memory effect (SME) and superelasticity (SE) similar to dense NiTi alloys. To optimize porous NiTi SMAs in bone implant applications, the current research focuses on the fabrication methods and surface modification techniques in order to obtain adjustable bone-like structures with good mechanical properties, excellent superelasticity, as well as bioactive passivation on the entire exposed surface areas to block nickel ion leaching and enhance the surface biological activity. This invited paper describes progress in the fabrication of the porous materials and our recent work on surface nanorization of porous NiTi scaffolds in bone grafts applications.

Summary
Editor's note
Attachment problems can be divided into two broad categories. First, attachment insecurity and disorganization characterize patterns of child/caregiver relationship that represent risk factors for later psychopathology. Second, so-called attachment disorders are categorical disorders of disrupted attachment usually associated with early social deprivation, neglect or maltreatment. These latter include both disinhibited attachment disorder, which reveals itself in indiscriminate sociability, and inhibited attachment disorder. In cases of attachment insecurity, various forms of intervention with parents appear to have effectiveness in increasing parental sensitivity but their impact on attachment per se is less clear cut. These interventions appear to work best when they are relatively brief and specifically target caregiver sensitivity. In more severe cases, especially those involving attachment disorder, interventions may require placement of the children in adoptive homes. ‘Holding therapy’ lacks empirical support and may pose serious risk to children.
Introduction
Child attachment refers to particular key characteristics of the relationship between child and specific caregiver that are known to be strongly associated with social development and mental health. Research on normative patterns of attachment in infancy find that attachment insecurity (including ‘disorganization’) is a relative psychosocial risk factor for later development and is best conceptualized as a developmental risk variable on Axis V of a multiaxial classification (Green & Goldwyn, 2002).
Two less common forms of developmental disturbance associated with severe disruption or absence of early attachment relationships are recognized as Axis 1 clinical disorders in both DSM and ICD systems, although neither has yet received robust empirical validation.

Summary
We have some numbers that may surprise you, but first you need to supply some of your own. Make your best estimate in answering the following questions: What percentage of all accountants and auditors in the United States in 1983 were female? Now answer the same question for the year 2000. What about other math-intensive professions, say economists? What percentage of economists in the United States in 1983 and in 2000 were female? What about the percentage of all engineers who were female in 1983 and in 2000? Finally, is the difference in achievement scores between girls and boys much larger on tests of reading literacy or tests of mathematical literacy?
Are you fairly confident about your answers? Give yourself a “point” for each answer you supplied that is within five percentage points of the correct answer. According to the U.S. Bureau of the Census (2001), the majority of accountants and auditors in 2000 were female (56.7%), up considerably from 1983 when females made up slightly more than one-third of this profession (36.7%). The comparable values for economists in 1983 and 2000 were 37.9% and 53.3%. Surprised that these values are so high? Most people are. What about engineers? Females were 5.9% of all engineers in 1983 and still only 9.9% in 2000 – values that are probably closer to what most people estimated for all these math-intensive professions.
