RESUMO
OBJECTIVE: This research investigates how watching videos of police violence and experiences with police contributes to health disparities in well-being that disproportionately negatively affect Black Americans. METHOD: A large-scale survey of Americans (n = 1,240; nBlack American = 286, nWhite American = 954) examined the impact of negative experiences with police and watching violent policing videos as distal (i.e., external) stressors that contribute to symptoms of trauma. The proximal (i.e., internal) stressor of worrying about being stereotyped as criminal by police was also examined. RESULTS: Those who identified as Black were more likely to report negative experiences with police, exposure to violent policing videos, and greater worry about being stereotyped as criminal by police than those who identified as White. The three stressors were, in turn, associated with experiencing trauma symptoms. CONCLUSIONS: Exposure to violent policing videos is disproportionately associated with well-being for Black Americans, even when accounting for direct experiences with police. These findings demonstrate the importance of considering vicarious trauma in therapeutic settings and have implications for dissemination of these videos through media channels.

RESUMO
The effectiveness of menu calorie labeling in limiting the amount of calories selected has been called into question since it was mandated within the Affordable Care Act. This study examined how contexts that are known to influence motivational and information processing might limit the effectiveness of calorie labeling in order to shed some light on the mixed findings in this area. An online experiment was conducted in which calorie labels were paired or not paired with visual cues in different motivational contexts: greater and lesser variety and energy density choices available. Results contribute to the general conclusion that calorie labels are not particularly effective. Specifically, the only context in which a calorie label succeeded in reducing calories selected was a high variety mix of low and high energy density foods with visual food cues present; however, this type of context elicited the greatest number of calories selected on average, even more than when only highly energy density items were present. The findings from this study add to the body of knowledge about the effectiveness of calorie labeling by defining some boundary conditions on whether and when the presence of calorie labels are likely to reduce caloric intake. This knowledge is helpful in furthering food selection and choice research, but also may help health practitioners design effective intervention strategies.

OBJECTIVE: The objective of this study was to describe family visitation policies, facilities, and support in Australia and New Zealand (ANZ) intensive care units (ICUs). METHODS: A survey was distributed to all Australian and New Zealand ICUs reporting to the Australian and New Zealand Intensive Care Society Centre for Outcomes and Resources Evaluation Critical Care Resources (CCR) Registry in 2018. Data were obtained from the survey and from data reported to the CCR Registry. For this study, open visiting (OV) was defined as allowing visitors for more than 14 h per day. SETTING AND PARTICIPANTS: This study included all Australian and New Zealand ICUs reporting to CCR in 2018. MAIN OUTCOME MEASURES: The main outcome measures were family access to the ICU and visiting hours, characteristics of the ICU waiting area, and information provided to and collected from the relatives. FINDINGS: Fifty-six percent (95/170) of ICUs contributing to CCR responded, representing 44% of ANZ ICUs and a range of rural, metropolitan, tertiary, and private ICUs. Visiting hours ranged from 1.5 to 24 h per day, with 68 (72%) respondent ICUs reporting an OV policy, of which 64 (67%) ICUs were open to visitors 24 h a day. A waiting room was part of the ICU for 77 (81%) respondent ICUs, 74 (78%) reported a separate dedicated room for family meetings, and 83 (87%) reported available social worker services. Most ICUs reported facilities for sleeping within or near the hospital. An information booklet was provided by 64 (67%) ICUs. Only six (6%) ICUs required personal protective equipment for all visitors, and 76 (80%) required personal protective equipment for patients with airborne precautions. CONCLUSIONS: In 2018, the majority of ANZ ICUs reported liberal visiting policies, with substantial facilities and family support.

BACKGROUND: Family-centred critical care recognises the impact of a loved one's critical illness on his relatives. Open visiting is a strategy to improve family satisfaction and psychological outcomes by permitting unrestricted or less restricted access to visit their family member in the intensive care unit (ICU). However, increased family presence may result in increased workload and a risk of burnout for ICU staff. OBJECTIVES: The objective of this study was to evaluate ICU staff perceptions regarding visiting hours and family access in Australian and New Zealand ICUs. Secondary outcomes included an evaluation of current visiting policies, witnessed events in ICUs, and barriers to implementing open visiting policies. DESIGN: A web-based survey open to all healthcare workers in Australia and New Zealand ICUs was distributed through local, state-based, and national critical care networks. Open visiting was defined as ICUs open for visiting >14 h per day. MAIN RESULTS: We received 1255 valid responses. Most respondents were nurses (n = 930, 74.1%) with a median critical care experience of 10 y. Most worked in open visiting ICUs (n = 749, 59.7%). Reported visiting hours varied greatly with a median of 20 h per day (interquartile range: 10-24 h). Open visiting was perceived as beneficial for the relatives, but less so for patients and staff (relatives: n = 845, 67.3%, patients: n = 561, 44.7%, staff: n = 257, 20.5%, p < 0.0001). Respondents from closed visiting units and nurses identified more risks from open visiting than other professional groups. Generally, staff preferred not to change from their current practice. CONCLUSION: We report that staff perceived open visiting as beneficial for relatives, but also identified risks to themselves, including increased workload, a risk of burnout, and a risk of occupational violence. Reluctance to change highlights the importance of addressing staff perceptions when implementing an open visiting policy.

Social norms play a key role in dietary behaviors. This study tested the underlying mechanism behind social norm effects in the context of the influences of social eating cues (individual vs. group eating cues) in fast food advertisements on motivational responses. Our results indicated that food ads with group eating cues elicited stronger appetitive activation resulting in greater orbicularis oculi activation and greater skin conductivity level, indicating more positive emotional feelings and more sympathetic arousal, compared to food ads with individual eating cues. Group eating cues also led to more favorable self-reported attitudes toward the advertised food products and brands. Overall, findings from this study suggest that exposure to food ads with group eating cues yield greater appetitive responses toward these types of ads and their products, likely creating a stronger degree of perceived social support. Implications are discussed.

This study combined theory from the fields of communication, behavioral ecology, and ecological psychology to examine how relevant factors about food influence the timing and trajectory of our decision-making after exposure to food advertisements. Young healthy adult participants (N = 108) completed a forced-choice, speeded decision-making latency task before and after viewing a set of advertisements. Results suggested that participants were more appetitively motivated by more energy-dense foods (i.e., higher calorie per gram) using direct food cues (i.e., were directly available to the senses, were visible), but after exposure to advertisements, this predisposition was less pronounced. Advertisement food cues were also important in decision-making, especially in coalition with the food cues used in the decision-making task stimuli. This study supports an optimal foraging perspective being expanded to human behavioral contexts in a modern landscape. Food advertising and packaging cues interacted with energy density level of food to provide information relevant to biological imperatives, which significantly altered food consumption decisions.

In this study, we evaluate a coronal mass ejection (CME) arrival prediction tool that utilizes the wide-angle observations made by STEREO's heliospheric imagers (HI). The unsurpassable advantage of these imagers is the possibility to observe the evolution and propagation of a CME from close to the Sun out to 1 AU and beyond. We believe that by exploiting this capability, instead of relying on coronagraph observations only, it is possible to improve today's CME arrival time predictions. The ELlipse Evolution model based on HI observations (ELEvoHI) assumes that the CME frontal shape within the ecliptic plane is an ellipse and allows the CME to adjust to the ambient solar wind speed; that is, it is drag based. ELEvoHI is used to perform ensemble simulations by varying the CME frontal shape within given boundary conditions that are consistent with the observations made by HI. In this work, we evaluate different setups of the model by performing hindcasts for 15 well-defined isolated CMEs that occurred when STEREO was near L4/5, between the end of 2008 and the beginning of 2011. In this way, we find a mean absolute error of between 6.2 ± 7.9 and 9.9 ± 13 hr depending on the model setup used. ELEvoHI is specified for using data from future space weather missions carrying HIs located at L5 or L1. It can also be used with near-real-time STEREO-A HI beacon data to provide CME arrival predictions during the next â¼7 years when STEREO-A is observing the Sun-Earth space.
RESUMO
In an effort to understand how different types of food cues in food ads are automatically encouraging unhealthy eating behaviors, the current study examined how the presence of actual food consumption behaviors (use cues) and presence of multiple individuals indorsing food products (social cues) in fast food ads would influence individual attentional and behavioral responses. A use cue (2) x social cue (2) x repetition (3) fully within-subjects factorial design experiment with young adults (N = 164) was conducted. Findings demonstrated that participants paid greater attention to the fast food ads which contained multiple people (group cue) eating the advertised food products (use cue) when compared to other types of fast food ads. In addition, participants also self-reported greater social support and purchase intention when seeing use and group cues in ads. Understanding how these cues function in food advertising to encourage unhealthy eating may help health practitioners and individuals create more helpful intervention strategies. Further, applying these marketing tactics to ads for food products that are healthier (i.e., less energy dense and more nutrient dense) may help to maximize healthy food palatability, thereby increasing motivation for viewers to make autonomous decisions about eating healthier.

Extensive research demonstrates that exposure to threatening anti-tobacco messages can lead to defensive message processing which reduces message effectiveness. However, research investigating whether this effect is moderated by the smoking status of the message viewer is lacking. In this study, participants (N = 48 smokers and N = 51 non-smokers) viewed and rated secondhand smoke anti-tobacco messages depicting both smoking cues and threat content, or messages depicting neither while heart rate, skin conductance, and facial EMG were recorded. Post viewing, self-reported emotional experience, level of counterarguing, and recognition memory were measured. In support of the LC4MP, there were no differences between smokers and non-smokers' responses for non-threatening messages absent in smoking cues. However, messages that contained both smoking cues and threat content were defensively processed by smokers - but not non-smokers - as indicated by significantly faster heart rate, lower recognition memory and higher self-reported negativity, arousal, and counterarguments. The theoretical and practical implications are discussed.

The bulk of mass media and substance cue research has examined the processes and effects of substance cue images in isolation under controlled experimental conditions. However, little attention has been devoted to delineating the specific outcomes associated with simultaneous polysubstance depictions. This study experimentally examined whether alcohol, marijuana, and junk food mediated cues influence craving independently and whether craving for these substances is co-facilitated by simultaneous polysubstance cue depictions. At a laboratory session, participants reported their craving to substance cues in isolation and when paired with one another. The results from this study support the incentive sensitization model and polysubstance literature indicating that alcohol and marijuana cues facilitate craving for both alcohol and marijuana above and beyond when alcohol and marijuana cues are depicted in isolation for high and low users of each substance. Junk food craving was not facilitated by alcohol and marijuana cues. Theoretically, this study supports the notion that simultaneous and repeated use of multiple substances results in greater hypersensitivity and craving to mediated polysubstance cues than the cues in isolation. Practically, this study provides a word of caution for researchers examining craving responses to mediated substance cue messages and recommendations for health professionals and message designers.

This study examined how the presence of substance cues interacted with arousing content level in public service announcements (PSAs) to affect human motivational activation, and as a result, affect cognitive information processing. A 2 (arousing content level: high vs. low arousing content fear appeal PSAs) × 2 (substance cue: absence vs. presence) × 4 (repetition) within-subject factorial design experiment was conducted. Overall, the results indicated that the presence of substance cues in high arousing content fear appeal messages elicited defensive processing, yielding poor audio recognition memory sensitivity and a more conservative criterion bias. However, the addition of substance cues to low arousing content fear appeal messages increased audio recognition sensitivity. The presence of substance cues decreased visual recognition regardless of the arousing content level. Implications and future research are discussed.

At least four workers at a metal recycling facility were hospitalized and one died after exposure to chlorine gas when it was accidentally released from an intact, closed-valved cylinder being processed for scrap metal. This unintentional chlorine gas release marks at least the third such incident at a metal recycling facility in the United States since 2010. We describe the fatal case of the worker whose clinical course was consistent with acute respiratory distress syndrome (ARDS) following exposure to high concentrations of chlorine gas. This case report emphasizes the potential risk of chlorine gas exposure to metal recycling workers by accepting and processing intact, closed-valved containers. The metal recycling industry should take steps to increase awareness of this established risk to prevent future chlorine gas releases. Additionally, public health practitioners and clinicians should be aware that metal recycling workers are at risk for chlorine gas exposure.

This study examined individuals' physiological and cognitive responses to different types of emotionally experienced content located in obesity prevention fear appeals. Results suggested that experienced valence impacted individuals' attention and memory as a function of experienced arousal level. Local content that created coactive highly arousing experiences received the most attention, though visual recognition suggested these messages were more difficult to encode. Local content that created negative moderately arousing experiences was best encoded. Global message evaluation data suggest that moderately arousing messages with a change in experienced valence may prove to be most effective, as they ensure attention and good memory while keeping high self-reported interest, and a high level of perceived severity of obesity. Implications and suggestions for future research are discussed.

From an ecological perception perspective (Gibson, 1977), the availability of perceptual information alters what behaviors are more and less likely at different times. This study examines how perceptual information delivered in food advertisements and packaging alters the time course of information processing and decision making. Participants categorized images of food that varied in information delivered in terms of color, glossiness, and texture (e.g., food cues) before and after being exposed to a set of advertisements that also varied in this way. In general, items with more direct cues enhanced appetitive motivational processes, especially if they were also advertised with direct food cues. Individuals also chose to eat products that were packaged with more available direct food cues compared to opaque packaging.

More energy dense foods are preferable from an optimal foraging perspective, which suggests these foods are more motivationally relevant due to their greater capability of fulfilling biological imperatives. This increase in motivational relevance may be exacerbated in circumstances where foraging will be necessary. This study examined how food energy density and presence of food in the immediate environment interacted to influence motivational processing of food advertisements. N = 58 adults viewed advertisements for foods varying in energy density in contexts where the advertised food was actually present in the viewing room or not. Advertisements for more energy dense foods elicited greater skin conductivity level compared to ads for less energy dense foods when food was not present. All ads elicited decreases in corrugator supercilii activation indicating positive emotional response resultant from appetitive motivational activation, though the greatest activation was exhibited toward higher energy density foods when food was present. This supports an optimal foraging perspective and has implications for healthy eating interventions.

This study explores how people respond to images of junk versus healthy food as a function of their eating habits and food knowledge. The experiment reported here proposed and tested the idea that those with unhealthy eating habits but highly knowledgeable about healthy eating would feel more positive and also more negative toward junk food images compared to images of healthy food because they may perceive them as risky--desirable but potentially harmful. The psychophysiological data collected from participants during their exposure to pictures of junk versus healthy food supported this idea. In addition, unhealthy eaters compared to healthy eaters with the same degree of food knowledge responded more positively to all food items. The findings are critical from a health communication perspective. Because unhealthy eaters produce stronger emotional responses to images of junk food, they are more likely to process information associated with junk food with more cognitive effort and scrutiny. Thus, when targeting this group and using images of junk food, it is important to combine these images with strong message claims and relevant arguments; otherwise, if the arguments are perceived as irrelevant or weak, the motivational activation associated with junk food itself may transfer into an increased desire to consume the unhealthy product.

Obliterative bronchiolitis in five former coffee processing employees at a single workplace prompted an exposure study of current workers. Exposure characterization was performed by observing processes, assessing the ventilation system and pressure relationships, analyzing headspace of flavoring samples, and collecting and analyzing personal breathing zone and area air samples for diacetyl and 2,3-pentanedione vapors and total inhalable dust by work area and job title. Mean airborne concentrations were calculated using the minimum variance unbiased estimator of the arithmetic mean. Workers in the grinding/packaging area for unflavored coffee had the highest mean diacetyl exposures, with personal concentrations averaging 93 parts per billion (ppb). This area was under positive pressure with respect to flavored coffee production (mean personal diacetyl levels of 80 ppb). The 2,3-pentanedione exposures were highest in the flavoring room with mean personal exposures of 122 ppb, followed by exposures in the unflavored coffee grinding/packaging area (53 ppb). Peak 15-min airborne concentrations of 14,300 ppb diacetyl and 13,800 ppb 2,3-pentanedione were measured at a small open hatch in the lid of a hopper containing ground unflavored coffee on the mezzanine over the grinding/packaging area. Three out of the four bulk coffee flavorings tested had at least a factor of two higher 2,3-pentanedione than diacetyl headspace measurements. At a coffee processing facility producing both unflavored and flavored coffee, we found the grinding and packaging of unflavored coffee generate simultaneous exposures to diacetyl and 2,3-pentanedione that were well in excess of the NIOSH proposed RELs and similar in magnitude to those in the areas using a flavoring substitute for diacetyl. These findings require physicians to be alert for obliterative bronchiolitis and employers, government, and public health consultants to assess the similarities and differences across the industry to motivate preventive intervention where indicated by exposures above the proposed RELs for diacetyl and 2,3-pentanedione.

RATIONALE: Obliterative bronchiolitis in former coffee workers prompted a cross-sectional study of current workers. Diacetyl and 2,3-pentanedione levels were highest in areas for flavoring and grinding/packaging unflavored coffee. METHODS: We interviewed 75 (88%) workers, measured lung function, and created exposure groups based on work history. We calculated standardized morbidity ratios (SMRs) for symptoms and spirometric abnormalities. We examined health outcomes by exposure groups. RESULTS: SMRs were elevated 1.6-fold for dyspnea and 2.7-fold for obstruction. The exposure group working in both coffee flavoring and grinding/packaging of unflavored coffee areas had significantly lower mean ratio of forced expiratory volume in 1 s to forced vital capacity and percent predicted mid-expiratory flow than workers without such exposure. CONCLUSION: Current workers have occupational lung morbidity associated with high diacetyl and 2,3-pentanedione exposures, which were not limited to flavoring areas.

This study assessed relationships among individual differences in trait motivational reactivity, executive functioning, and neurovisceral regulation of emotion and attention indexed via resting heart rate variability (rHRV). We derived predictions regarding these relationships according to neurovisceral neural network theory. Because lower rHRV has been suggested as an endophenotype of less adaptive behaviour, low rHRV individuals were predicted to have high aversive and low appetitive trait motivational reactivity, while high rHRV individuals were predicted to have high reactivity in both appetitive and aversive motivational systems. These predictions were supported. Motivational reactivity also was related to executive functioning deficits, although the pattern of results was not in the predicted direction. Results suggest that trait motivational reactivity scores are related to visceral responses proposed in the neurovisceral integration circuit as well as in the modulation of these responses by higher-order cognitive control systems related to executive function.

Individuals who report perceived stress often eat more unhealthy foods and more calories than those with lower stress levels, though individual differences and contexts are important. This study investigated how visual food cues on fast-food menus may increase calorie consumption intentions due to their potential motivational influences. A 2 (presence or absence of visual cues) x 4 (exemplar fast-food restaurant menu) fractionated experiment administered online (N = 325) indicated that when participants viewed menus with visual cues, they selected a greater number of calories to consume. Additionally, data showed an interaction effect of perceived stress and visual cues revealing that visual elements incentivized participants reporting higher stress to select more calories whereas visual cues did not have this effect for people reporting lower levels of perceived stress. Though important limitations exist, a key takeaway is that food cue exposure is another important factor to consider when predicting how stress may affect eating decisions.
