Objective:
The purpose of this study is to determine if healthier neighbourhood food environments are associated with healthier diet quality.
Design:This was a cross-sectional study using linear regression models to analyse data from the Maastricht Study. Diet quality was assessed using data collected with a FFQ to calculate the Dutch Healthy Diet (DHD). A buffer zone encompassing a 1000 m radius was created around each participant home address. The Food Environment Healthiness Index (FEHI) was calculated using a Kernel density analysis within the buffers of available food outlets. The association between the FEHI and the DHD score was analysed and adjusted for socio-economic variables.
Setting:The region of Maastricht including the surrounding food retailers in the Netherlands.
Participants:7367 subjects aged 40–75 years in the south of the Netherlands.
Results:No relationship was identified between either the FEHI (B = 0·62; 95 % CI = –2·54, 3·78) or individual food outlets, such as fast food (B = –0·07; 95 % CI = –0·20, 0·07) and diet quality. Similar null findings using the FEHI were identified at the 500 m (B = 0·95; 95 % CI = –0·85, 2·75) and 1500 m (B = 1·57; 95 % CI = –3·30, 6·44) buffer. There was also no association between the food environment and individual items of the DHD including fruits, vegetables and sugar-sweetened beverages.
Conclusion:The food environment in the Maastricht area appeared marginally unhealthy, but the differences in the food environment were not related to the quality of food that participants reported as intake.

Purpose:
Systemic-to-pulmonary collateral flow is a well-recognised phenomenon in patients with single ventricle physiology, but remains difficult to quantify. The aim was to compare the reported formula’s that have been used for calculation of systemic-to-pulmonary-collateral flow to assess their consistency and to quantify systemic-to-pulmonary collateral flow in patients with a Glenn and/or Fontan circulation using four-dimensional flow MRI (4D flow MR).
Methods:Retrospective case–control study of Glenn and Fontan patients who had a 4D flow MR study. Flows were measured at the ascending aorta, left and right pulmonary arteries, left and right pulmonary veins, and both caval veins. Systemic-to-pulmonary collateral flow was calculated using two formulas: 1) pulmonary veins – pulmonary arteries and 2) ascending aorta – caval veins. Anatomical identification of collaterals was performed using the 4D MR image set.
Results:Fourteen patients (n = 11 Fontan, n = 3 Glenn) were included (age 26 [22–30] years). Systemic-to-pulmonary collateral flow was significantly higher in the patients than the controls (n = 10, age 31.2 [15.1–38.4] years) with both formulas: 0.28 [0.09–0.5] versus 0.04 [−0.66–0.21] l/min/m2 (p = 0.036, formula 1) and 0.67 [0.24–0.88] versus -0.07 [−0.16–0.08] l/min/m2 (p < 0.001, formula 2). In patients, systemic-to-pulmonary collateral flow differed significantly between formulas 1 and 2 (13% versus 26% of aortic flow, p = 0.038). In seven patients, veno-venous collaterals were detected and no aortopulmonary collaterals were visualised.
Conclusion:4D flow MR is able to detect increased systemic-to-pulmonary collateral flow and visualise collaterals vessels in Glenn and Fontan patients. However, the amount of systemic-to-pulmonary collateral flow varies with the formula employed. Therefore, further research is necessary before it could be applied in clinical care.

Objective:
To investigate a cluster of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections in employees working on 1 floor of a hospital administration building.
Methods:Contact tracing was performed to identify potential exposures and all employees were tested for SARS-CoV-2. Whole-genome sequencing was performed to determine the relatedness of SARS-CoV-2 samples from infected personnel and from control cases in the healthcare system with coronavirus disease 2019 (COVID-19) during the same period. Carbon dioxide levels were measured during a workday to assess adequacy of ventilation; readings >800 parts per million (ppm) were considered an indication of suboptimal ventilation. To assess the potential for airborne transmission, DNA-barcoded aerosols were released, and real-time polymerase chain reaction was used to quantify particles recovered from air samples in multiple locations.
Results:Between December 22, 2020, and January 8, 2021, 17 coworkers tested positive for SARS-CoV-2, including 13 symptomatic and 4 asymptomatic individuals. Of the 5 cluster SARS-CoV-2 samples sequenced, 3 were genetically related, but these employees denied higher-risk contacts with one another. None of the sequences from the cluster were genetically related to the 17 control sequences of SARS-CoV-2. Carbon dioxide levels increased during a workday but never exceeded 800 ppm. DNA-barcoded aerosol particles were dispersed from the sites of release to locations throughout the floor; 20% of air samples had >1 log10 particles.
Conclusions:In a hospital administration building outbreak, sequencing of SARS-CoV-2 confirmed transmission among coworkers. Transmission occurred despite the absence of higher-risk exposures and in a setting with adequate ventilation based on monitoring of carbon dioxide levels.

This study examined: (1) school-based avoidance among students with problematic anxiety, (2) teachers’ levels of accommodation of avoidant behaviour, and (3) the relation between teacher accommodation and student avoidance and anxiety. Participants included 31 elementary school students with problematic anxiety (mean age = 7.7 years; range 5–11; 58% female; 71% White) and their teachers (mean age = 41.1 years; 100% female; 100% White). Children completed interviews about their anxiety, and teachers reported on students’ avoided situations and completed a questionnaire about their own use of accommodation. Results indicated that the most commonly avoided situations involved individual and group academic performance (e.g., reading aloud in front of class). All teachers engaged in some form of accommodating behaviour more than one day a week (e.g., assisted a student in avoiding things that might make him/her more anxious), and teachers who reported engaging in more accommodating behaviours had students with higher avoidance and anxiety. Findings suggest that additional training and research on teachers’ behaviours that maintain and/or reduce anxiety via reducing accommodating behaviours appears warranted.

The current study examined elementary (or primary) school teachers’ knowledge of student anxiety and evidence-based anxiety reduction strategies, whether this knowledge was associated with their use of evidence-based anxiety reduction strategies in the classroom, and correlates of teacher knowledge and use of anxiety reduction strategies in the classroom. Fifty-one volunteer elementary teachers (98% female; 98% White) participated and completed questionnaires about: themselves and work-related factors (e.g., years of teaching experience, self-efficacy), knowledge of student anxiety and anxiety treatment (e.g., core manifestations of anxiety such as physiological arousal, behavioural avoidance, and anxious thoughts), and use of anxiety reduction strategies in the classroom (e.g., relaxation strategies, encouraging the use of coping self-talk, and gradual exposure to feared situations). Results indicated that the average score on the knowledge assessment was 57% and knowledge levels were unrelated to self-reported use of anxiety reduction strategies. The most robust correlate of knowledge of anxiety and use of anxiety reduction strategies was teachers’ perceived personal accomplishment. Findings suggest additional teacher training to increase knowledge about student anxiety and use of evidence-based anxiety reduction strategies in the classroom is warranted.

Titanium dioxide nanotubes (TiO2-NT) have been synthesized via an electrochemical anodization strategy followed by calcination under different temperatures to form TiO2 nanostructures of anatase and rutile crystal phases. The nanotube-on-Ti structure is further used as a substrate for calcium hydroxyapatite (HAp) coating. The effect of TiO2 morphology and crystal phases (i.e. amorphous, anatase and rutile) on the coating efficiency of HAp has been investigated in comparison with HAp coating on bare Ti metal. The HAp coated TiO2-NT have been studied using X-ray absorption near-edge structure (XANES) at the Ti K- and Ca K-edge. The results show that TiO2 of amorphous and anatase phases are of comparably good performance for HAp crystallization, and both are better than rutile TiO2, while HAp is hardly found on bare Ti. The implications of the findings are discussed.

Summary
Legal personality is an attribute that is necessary in order for a person or entity to enter into legal relationships. Only legal persons can enjoy and enforce legal rights and obligations. In all national jurisdictions, whether or not a person or an entity is a legal person is determined by the domestic law of that jurisdiction. Internationally, this is determined by the rules of Public International Law. Legal personality of an entity is manifested in its capacity to sue or be sued in domestic or international courts and tribunals.
LEGAL PERSONS
Under the domestic laws of all nations, a legal person can either be a natural person, that is, an individual human being, or an artificial person. For a natural person, legal personality attaches at birth. Until birth, a person does not possess legal personality and thus cannot sue or be sued for matters occurring prior to his or her birth.
Artificial persons in domestic law are entities that are incorporated under domestic laws and conferred legal personality by law upon incorporation. Incorporation can be by registration, as in the case of companies. Alternatively, incorporation can be by statutes passed by Parliament. For example, in Singapore, statutory boards are all established by legislation which confers the body with legal personality and provides that it can sue and be sued. Historically, in some states, entities can also be incorporated by writs issued by the sovereign. Examples of these would be the many trading bodies during the heyday of European colonial expansion such as the Chartered Bank and the East India Company.
An artificial person is separate from a natural person or the entity involved in it. This means that the rights and liabilities of an artificial person are distinct from those of the natural person and entities, whether incorporated or not, who are its constituents.

Longitudinal growth trajectories of reading and math achievement were studied in four primary school grade cohorts (GCs) of a large urban district to examine academic risk and resilience in homeless and highly mobile (H/HM) students. Initial achievement was assessed when student cohorts were in the second, third, fourth, and fifth grades, and again 12 and 18 months later. Achievement trajectories of H/HM students were compared to low-income but nonmobile students and all other tested students in the district, controlling for four well-established covariates of achievement: sex, ethnicity, attendance, and English language skills. Both disadvantaged groups showed markedly lower initial achievement than their more advantaged peers, and H/HM students manifested the greatest risk, consistent with an expected risk gradient. Moreover, in some GCs, both disadvantaged groups showed slower growth than their relatively advantaged peers. Closer examination of H/HM student trajectories in relation to national test norms revealed striking variability, including cases of academic resilience as well as problems. H/HM students may represent a major component of “achievement gaps” in urban districts, but these students also constitute a heterogeneous group of children likely to have markedly diverse educational needs. Efforts to close gaps or enhance achievement in H/HM children require more differentiated knowledge of vulnerability and protective processes that may shape individual development and achievement.

Miniaturized piezoelectric sensors based on Microelectromechanical Systems (MEMS) offer the advantages of reduced size, reduced power consumption, increased sensitivity coupled with the ability to form compact multi-sensor arrays. Fabrication of such sensors from single crystal materials further insure more highly reproducible and stable devices with improved performance. In this paper, we describe the integration of MBE grown AlN films onto photoelectrochemically machined SiC microcantilevers and membranes. AlN exhibits excellent piezoelectric properties, including an electromechanical coupling coefficient of 0.088 and a high in-plane acoustic velocity (∼5700m/sec) as well as excellent thermal-mechanical compatibility with SiC. The fabrication of AlN-SiC-based microresonators and flexural plate wave devices, and their application to chemical, biological and fluid sensing, are reported.

As memory continues to be scaled to ever smaller dimensions, the floating-gate memory transistor, which offers a single-element storage cell, becomes more attractive. Typically, this structure has been reserved for nonvolatile applications, where the comparatively high voltages, slow write speeds, and limited cyclability could be tolerated. However, if the floating-gate, which is usually a continuous film of polysilicon, is replaced with a discontinuous film of small floating islands (nano-crystals), a new set of tradeoffs in these performance factors becomes possible, opening the door to broader applications. If these islands are further reduced to the point where Coulomb charging or energy quantization effects become relevant, it is possible to control the charge on the islands at a single (or few) electron level, which offers very low power operation and may enable new functionality. This paper will discuss design and fabrication of these memories, experimental results on fabricated devices, and modeling of what could ultimately be achieved, as well as what limitations will ultimately be reached.
