The history of motorcycle helmet legislation in the United States reflects the extent to which concerns about individual liberties have shaped the public health debate. Despite overwhelming epidemiological evidence that motorcycle helmet laws reduce fatalities and serious injuries, only 20 states currently require all riders to wear helmets. During the past 3 decades, federal government efforts to push states toward enactment of universal helmet laws have faltered, and motorcyclists’ advocacy groups have been successful at repealing state helmet laws. This history raises questions about the possibilities for articulating an ethics of public health that would call upon government to protect citizens from their own choices that result in needless morbidity and suffering.

Motorcycle riders account for a disproportionately high number of traffic injuries and fatalities compared to occupants of other vehicle types. Though research has demonstrated the benefits of helmet use in preventing serious and fatal injuries in the event of a crash, helmet use has remained relatively stable in the United States, where the most recent national estimates show a 64% use rate. Use rates have been markedly lower among those states that do not have a universal helmet law for all riders. In 2012, the state of Michigan repealed its longstanding mandatory helmet use law. In order to gain insights as to the effects of this legislative change, a study was conducted to examine short-term changes in helmet use and identify factors associated with use rates. A statewide direct observation survey was conducted 1 year after the transition from a universal helmet law to a partial helmet law. A random parameters logistic regression model was estimated to identify motorcyclist, roadway, and environmental characteristics associated with helmet use. This modeling framework accounts for both intravehicle correlation (between riders and passengers on the same motorcycle) as well as unobserved heterogeneity across riders due to important unobserved factors. Helmet use was shown to vary across demographic segments of the motorcyclist population. Use rates were higher among Caucasian riders, as well as among those age 60 and above. No significant difference was observed between male and female riders. Use was also found to vary geographically, temporally, and with respect to various environmental characteristics. Geographically, helmet use rates tended to be correlated with historical restraint use trends, which may be reflective of riding environment and general differences in the riding population. To this end, rates were also highly variable based upon the type of motorcycle and whether the motorcyclist was wearing high-visibility gear. The study results demonstrate

Motorcycles are the most popular vehicles in Taiwan, where more than 14.8 million motorcycles (1 motorcycle per 1.6 people) are in service. Despite the mandatory helmet law passed in 1997, less than 80% of motorcyclists in Taiwan wear helmets. The objective of this study was to analyze the effect of using motorcycle helmets on fatality rates. A clinical data set including 2,868 trauma patients was analyzed; the cross-sectional registration database was administered by a university medical center in Central Taiwan. A path analysis framework and multiple logistic regressions were used to estimate the marginal effect of helmet use on mortality. Using a helmet did not directly reduce the mortality rate but rather indirectly reduced the mortality rate through intervening variables such as the severity of head injuries, number of craniotomies, and complications during therapeutic processes. Wearing a helmet can reduce the fatality rate by 1.3%, the rate of severe head injury by 34.5%, the craniotomy rate by 7.8%, and the rate of complications during therapeutic processes by 1.5%. These rates comprise 33.3% of the mortality rate for people who do not wear helmets, 67.3% of the severe head injury rate, 60.0% of the craniotomy rate, and 12.2% of the rate of complications during therapeutic processes. Wearing a helmet and trauma system designation are crucial factors that reduce the fatality rate.

Patients presenting to emergency departments (ED) for injuries resulting from recreational activities represent a unique source of information on important directions for injury prevention efforts. We describe the epidemiology of non-motorized wheeled activity-related injury in pediatric patients presenting to Canadian EDs as well as patients' helmet use. Data for the years 2004 to 2009 were abstracted from the Canadian Hospitals Injury Reporting and Prevention Program (CHIRPP), a national ED injury surveillance program in fifteen hospitals. Most of the 28 618 children aged 1 to 16 years injured during non-motorized wheeled activities were injured while cycling, followed by skateboarding. Most injuries occurred among boys. Children injured on scooters tended to be younger whereas skateboarders were the oldest. On average, the number of all injuries decreased by 6% over the time period. Falls were the most common mechanism of injury; 8.3% of patients had head injuries, which were seen more often among cyclists than other wheeled-activity users. Helmet use was greatest among cyclists (62.2%) and lowest among skateboarders (32.9%). Injured patients presenting to EDs in jurisdictions with legislation mandating helmet use had 2.12 greater odds of helmet use and 0.86 lesser odds of head injury compared with those presenting in jurisdictions without helmet laws. These results provide further evidence that legislation mandating helmet use may be an effective way of reducing injury among all wheeled-activity users. The small number of patients who presented with helmet use and protective gear (59.4% overall) suggests that this remains an area for intervention.

Like many sports involving high speeds and body contact, head injuries are a concern for short track speed skating athletes and coaches. While the mandatory use of helmets has managed to nearly eliminate catastrophic head injuries such as skull fractures and cerebral haemorrhages, they may not be as effective at reducing the risk of a concussion. The purpose of this study was to evaluate the performance characteristics of speed skating helmets with respect to managing peak linear and peak rotational acceleration, and to compare their performance against other types of helmets commonly worn within the speed skating sport. Commercially available speed skating, bicycle and ice hockey helmets were evaluated using a three-impact condition test protocol at an impact velocity of 4 m/s. Two speed skating helmet models yielded mean peak linear accelerations at a low-estimated probability range for sustaining a concussion for all three impact conditions. Conversely, the resulting mean peak rotational acceleration values were all found close to the high end of a probability range for sustaining a concussion. A similar tendency was observed for the bicycle and ice hockey helmets under the same impact conditions. Speed skating helmets may not be as effective at managing rotational acceleration and therefore may not successfully protect the user against risks associated with concussion injuries.

The burden of motorcycle-related neuro-trauma in Ireland and associated helmet usage.

Motorcycles represent less than 2% of the licensed vehicles but motorcyclists account for 12% of road deaths in Ireland. The British Road Safety Authority has introduced the Sharp programme, which hopes to save 50 lives in the U.K. each year alone by helping riders to choose the best-fitting and safest helmets. We evaluated the pattern of head injuries sustained by motorcyclists referred to the two neurosurgical centres Beaumont Hospital and Cork University Hospital in Ireland and ascertained if the new SHARP guidelines could be of benefit in reducing the burden of motorcycle related neurotrauma and disability in Ireland. Despite Ireland having mandatory helmet laws almost a quarter of our motorcyclists with traumatic brain injury were unhelmeted. A significant reduction in mortality and morbidity is predicted if all motorcyclists in Ireland were to wear helmets that satisfied the SHARP criteria.

Do helmets worn for hurling fail to protect the ear? Identification of an emerging injury pattern.

Hurling is an Irish national game of stick and ball known for its ferocity, played by 190 000 players. Facial injuries were common but have been significantly reduced by legislation enforcing compulsory helmet wearing. Current standard helmets worn by hurlers do not offer protection to the external ear. Here we describe an emerging pattern of ear injuries and demonstrate the risk of external ear injuries in hurlers complying with current helmet safety standards. A 6-month retrospective analysis was carried out of patients attending Cork University Hospital (CUH) with ear lacerations sustained while hurling. Patient notes were reviewed and helmet manufacturers were interviewed. Seven patients were identified, all of whom sustained complex through ear lacerations while wearing helmets complying with current safety standards. Current helmet design fails to protect the external ear placing it at an increased risk of injury, a potential solution is to include ear protection in the helmet design.

many did not always wear a helmet because they found it inconvenient/uncomfortable. Analysis of trauma registry data showed that helmet wearing was associated with a significant reduction in head injuries among motorcyclists (adjusted odds ratio: 0.472, 95% CI: 0.327-0.684). This study highlights the low prevalence of helmet use and documents the potential reduction in the risk of head injuries to motorcyclists if this risk factor was addressed. The passage of a traffic amendment bill showed negligible impact on helmet use. This highlights the need for a multi-faceted strategy that includes media campaigns and widespread enforcement in addition to legislative change for improving helmet use.

2017-06-01

Full Text Available Spinal injury following direct loading of the head and neck is a rare sequel of bicycle crashes. Fatal head injuries following bicycle crashes have been described in great detail and safety measures such as bicycle helmets have been developed accordingly. Less frequently, however, potentially severe cervical spine injuries have been described. We present the case of a middle-aged female who sustained an ultimately fatal cervical spine injury following a collision with a car whilst biking wearing a helmet. We discuss the literature regarding the protective effects of bicycle helmets, the relevance to cervical spine injury and legislation on mandatory use of helmets for injury prevention.

Motorcycle crashes result in a significant health burden, including many fatal injuries and serious non-fatal head injuries. Helmets are highly effective in preventing such trauma, and jurisdictions that require helmet use of all motorcyclists have higher rates of helmet use and lower rates of head injuries among motorcyclists. The current study examines helmet use and characteristics of helmeted operators and their riding conditions in Michigan, following a weakening of the state's universal motorcycle helmet use law in April 2012. Data on police-reported crashes occurring during 2012-14 and from a stratified roadside observational survey undertaken in Southeast Michigan during May-September 2014 were used to estimate statewide helmet use rates. Observed helmet use was more common among operators of sports motorcycles, on freeways, and in the morning, and least common among operators of cruisers, on minor arterials, and in the afternoon. The rate of helmet use across the state was estimated at 75%, adjusted for roadway type, motorcycle class, and time of day. Similarly, the helmet use rate found from examination of crash records was 73%. In the observation survey, 47% of operators wore jackets, 94% wore long pants, 54% wore boots, and 80% wore gloves. Protective clothing of jackets and gloves was most often worn by sport motorcycle operators and long pants and boots most often by riders of touring motorcycles. Findings highlight the much lower rate of helmet use in Michigan compared with states that have a universal helmet use law, although the rate is higher than observed in many states with partial helmet laws. Targeted interventions aimed at specific groups of motorcyclists and situations where helmet use rates are particularly low should be considered to increase helmet use. Copyright © 2016 Elsevier Ltd.

The successful enactment of mandatory pharmacy technician certification in Kansas is described. In 2004, Kansas began requiring registration of all pharmacy technicians with the state board of pharmacy. Registration identified individuals working as pharmacy technicians but did not require any specific education or certification. In September 2012, the Kansas Board of Pharmacy created a task force of key stakeholders including pharmacists from multiple areas of practice, the University of Kansas School of Pharmacy, organizational leaders from the Kansas Council of Health-System Pharmacists (KCHP) and Kansas Pharmacists Association, and professional lobbyists. The goals of this task force were to research practices of technician certification in other states and to make recommendations to the state board of pharmacy on how Kansas could accomplish mandatory technician certification. The task force outlined the steps needed to achieve legislation that could be supported by the members. These topics included the creation of a technician trainee category, grandfathering certain technicians who had been practicing for a designated period of time, state board-approved exemptions, training requirements, age and education requirements, continuing-education requirements, and pharmacist:technician ratio. The recommendations were finalized at the August 2013 Kansas Pharmacy Summit, and the proposed legislation was introduced and passed during the 2014 legislative session. KCHP members learned many valuable lessons about advocacy and the legislative process with this initiative, including building relationships, working with legislators, and working with other professional organizations. The formation of a task force led to the successful passage of a bill granting the Kansas Board of Pharmacy the authority to issue regulations regarding mandatory pharmacy technician certification.

Moss, William C; King, Michael J

2015-03-24

A helmet blastometer for characterizing the direction, speed, magnitude, and duration of a blast event to determine the likelihood of blast-induced traumatic brain injury (biTBI). Time of arrival (TOA) gage sensors are mounted on a rigid outer shell of the helmet each producing a TOA signal in response to a fast rising blast induced positive pressure change above a predetermined threshold. A receiver analyzes the positive pressure changes from the gages to determine direction, speed, and magnitude of a blast. Other TOA gauge sensors can be used to produce a TOA signal in response to a negative pressure change below a predetermined threshold. The positive and negative pressure change TOA signals are used to determine blast duration. A second set of internal contact pressure sensors is connected to an inner liner of the helmet to detect contact pressure on a user's head to determine if biTBI has been sustained.

In Ottawa, between 2005 and 2009 there was an annual average of 47.2 head injuries due to ice skating in children and youth (1-19 years of age) requiring a visit to the emergency department, with the highest rates among those aged 5-14 years. Between 2002 and 2007, only 6% of children were wearing a helmet during ice skating when the head injury occurred. During indoor public skating sessions, 93% of children (skating helmet policy coupled with education and promotional activities on helmet use, participation and attitudes towards helmet use. An ice skating helmet policy for children (skating experience at indoor rinks during public skating sessions was developed, implemented and evaluated. Supportive activities such as discount coupons, promotional materials, a media launch, social marketing and staff training are described. The helmet policy was associated with increased helmet use for young children and for older children, youth and adults not included in the policy, without decreasing attendance to public skating sessions.

Barriers and Enablers to Enacting Child and Youth Related Injury Prevention Legislation in Canada

Directory of Open Access Journals (Sweden)

Linda Rothman

2016-07-01

Full Text Available Injury prevention policy is crucial for the safety of Canada’s children; however legislation is not adopted uniformly across the country. This study aimed to identify key barriers and enablers to enacting injury prevention legislation. Purposive snowball sampling identified individuals involved in injury prevention throughout Canada. An online survey asked respondents to identify policies that were relevant to them, and whether legislation existed in their province. Respondents rated the importance of barriers or enablers using a 5-point Likert type scale and included open-ended comments. Fifty-seven respondents identified the most common injury topics: bicycle helmets (44, 77%, cell phone-distracted driving (36, 63%, booster seats (28, 49%, ski helmets (24, 42%, and graduated driver’s licensing (21, 37%. The top enablers were research/surveillance, managerial/political support and professional group consultation, with much variability between injury topics. Open-ended comments emphasized the importance of a united opinion as an enabler and barriers included costs of protective equipment and inadequate enforcement of legislation. The results highlighted the importance of strategies that include research, management and community collaboration and that injury prevention topics should be addressed individually as information may be lost if topics are considered together. Findings can inform the process of turning injury prevention evidence into action.

In 2012, Michigan repealed its universal helmet law. Our study assessed the clinical impact of this repeal. Our trauma database was queried retrospectively for 2 motorcycle riding seasons before and 3 seasons after repeal. On-scene death data was obtained from the Medical Examiner. Helmet use in hospitalized patients decreased after the helmet law repeal. Non-helmeted patients had a significant increased rate of head injury. Non-helmeted patients were more likely to die during hospitalization. While, helmet use and drugs/alcohol status significantly affected the risk for head injury, only drug/alcohol had a significant effect on overall mortality. Following helmet law repeal, helmet use has decreased. Helmet status and drug/alcohol use was found to significantly increase risk of head injury. Although overall mortality was only affected by drug/alcohol use, non-helmeted patients did have a higher inpatient mortality. These findings deserve furthermore study and may provide a basis for reinstating the universal helmet law. Copyright © 2016 Elsevier Inc. All rights reserved.

A helmet-based system that was able to monitor the drowsiness of a soldier was developed. The helmet system monitored the electrocardiogram, electrooculogram and electroencephalogram (alpha waves) without constraints. Six dry electrodes were mounted at five locations on the helmet: both temporal sides, forehead region and upper and lower jaw strips. The electrodes were connected to an amplifier that transferred signals to a laptop computer via Bluetooth wireless communication. The system was validated by comparing the signal quality with conventional recording methods. Data were acquired from three healthy male volunteers for 12 min twice a day whilst they were sitting in a chair wearing the sensor-installed helmet. Experimental results showed that physiological signals for the helmet user were measured with acceptable quality without any intrusions on physical activities. The helmet system discriminated between the alert and drowsiness states by detecting blinking and heart rate variability (HRV) parameters extracted from ECG. Blinking duration and eye reopening time were increased during the sleepiness state compared to the alert state. Also, positive peak values of the sleepiness state were much higher, and the negative peaks were much lower than that of the alert state. The LF/HF ratio also decreased during drowsiness. This study shows the feasibility for using this helmet system: the subjects' health status and mental states could be monitored without constraints whilst they were working.

Helmet Use and Head Injury in Homer's Iliad.

2016-06-01

Homer's detailed descriptions of head injuries inflicted during the Trojan War are of particular interest to individuals in the medical community. Although studies have examined the prevalence of such injuries, none have examined the preventive measures taken to avoid them. An in-depth review of helmet use in Homer's Iliad was conducted to address this previously unexplored facet of the epic. An English translation of Homer's text was reviewed for all references to helmet use. The number of helmet references in each book was recorded, along with other pertinent details for each reference. There were 87 references to helmets (40 combat, 47 noncombat). The helmet belonged to a Greek warrior in 41 cases (47.1%), a Trojan warrior in 38 cases (43.6%), a divinity in 5 cases (5.7%), and a general group of warriors in 3 cases (3.4%). Helmet use provided protective benefit to Greek warriors at a rate of 30.0% (3 of 10) and Trojan warriors at a rate of 11.1% (2 of 18). This difference was not statistically significant (P = 0.23). The overall combined protective benefit of helmet use in the text was 17.9% (5 of 28). Helmets belonging to 15 specific Greek warriors and 18 specific Trojan warriors were referenced in the text. Helmets belonging to Hector (n = 12) and Achilles (n = 8) were most frequently mentioned. Helmet use and head injury both play a prominent role in Homer's Iliad. Helmets are frequently used in combat settings but with relatively little success. Helmets are also used in various noncombat settings. Copyright © 2016 Elsevier Inc. All rights reserved.

In traffic accidents involving motorcycles, paint traces can be transferred from the rider's helmet or smeared onto its surface. These traces are usually in the form of chips or smears and are frequently collected for comparison purposes. This research investigates the physical and chemical characteristics of the coatings found on motorcycles helmets. An evaluation of the similarities between helmet and automotive coating systems was also performed.Twenty-seven helmet coatings from 15 different brands and 22 models were considered. One sample per helmet was collected and observed using optical microscopy. FTIR spectroscopy was then used and seven replicate measurements per layer were carried out to study the variability of each coating system (intravariability). Principal Component Analysis (PCA) and Hierarchical Cluster Analysis (HCA) were also performed on the infrared spectra of the clearcoats and basecoats of the data set. The most common systems were composed of two or three layers, consistently involving a clearcoat and basecoat. The coating systems of helmets with composite shells systematically contained a minimum of three layers. FTIR spectroscopy results showed that acrylic urethane and alkyd urethane were the most frequent binders used for clearcoats and basecoats. A high proportion of the coatings were differentiated (more than 95%) based on microscopic examinations. The chemical and physical characteristics of the coatings allowed the differentiation of all but one pair of helmets of the same brand, model and color. Chemometrics (PCA and HCA) corroborated classification based on visual comparisons of the spectra and allowed the study of the whole data set at once (i.e., all spectra of the same layer). Thus, the intravariability of each helmet and its proximity to the others (intervariability) could be more readily assessed. It was also possible to determine the most discriminative chemical variables based on the study of the PCA loadings. Chemometrics

Children and cycle helmets -- the case against.

Science.gov (United States)

McCarthy, M

1996-03-01

Much of the literature on child cycling accidents appears to blame the child as a victim, as though children's activities of playing and travelling were somehow wrong and that children are at fault when an adult drives a car over them. This adult-centred approach then leads to the idea that children should protect themselves with helmets, and that they are to blame if they are injured. However, adults who continue to hold the fantasy that helmets might be of value should know that the British Standard for cycle helmets protects only in a vertical fall of 1 m -- certainly not motor vehicle crashes. Thicker motor cycle helmets would give better protection but, of course, are heavier (and therefore unsaleable). Yet even with compulsory wearing helmets, more motor cyclists still die of head injuries than pedal cyclists. In the Newcastle study, five times as many child pedestrians died of road accidents as child cyclists. Convinced helmeteers should recommend all children playing or travelling in the streets to wear helmets (presumably heavy motor-cycle helmets). Slightly more sceptical proponents might prefer half of them -- in a randomized controlled trial. Car driving appears to have as serious health consequences as tobacco, alcohol and drugs, and to be as addictive (McCarthy 1992). Helmets are similar to filters in cigarettes -- they give the illusion of safety to both consumer and producer of the product, but the illusion is fatal. Yet, for their cardiovascular and mental health, children should have the freedom to cycle in safety around where they live. A profound change in the habits of adults is needed, rather than suits of armour for children.

Based on archaeological finds and old Norse literature, this study describes the Scandinavian helmet tradition from the Bronze Age to the Viking Age, as well as the Viking culture, with special emphasis on weaponry and head protection. Contrary to what is commonly believed, the study shows that metal helmets must have been used very infrequently by the Vikings. In fact, only one Viking helmet has been retrieved in Scandinavia. Possible reasons for the widespread misconception that the Vikings wore helmets are discussed, and the responsibility for not correcting this misunderstanding is placed with the archaeological profession.

Simulation-based assessment for construction helmets.

Long, James; Yang, James; Lei, Zhipeng; Liang, Daan

2015-01-01

In recent years, there has been a concerted effort for greater job safety in all industries. Personnel protective equipment (PPE) has been developed to help mitigate the risk of injury to humans that might be exposed to hazardous situations. The human head is the most vulnerable to impact as a moderate magnitude can cause serious injury or death. That is why industries have required the use of an industrial hard hat or helmet. There have only been a few articles published to date that are focused on the risk of head injury when wearing an industrial helmet. A full understanding of the effectiveness of construction helmets on reducing injury is lacking. This paper presents a simulation-based method to determine the threshold at which a human will sustain injury when wearing a construction helmet and assesses the risk of injury for wearers of construction helmets or hard hats. Advanced finite element, or FE, models were developed to study the impact on construction helmets. The FE model consists of two parts: the helmet and the human models. The human model consists of a brain, enclosed by a skull and an outer layer of skin. The level and probability of injury to the head was determined using both the head injury criterion (HIC) and tolerance limits set by Deck and Willinger. The HIC has been widely used to assess the likelihood of head injury in vehicles. The tolerance levels proposed by Deck and Willinger are more suited for finite element models but lack wide-scale validation. Different cases of impact were studied using LSTC's LS-DYNA.

Application of Auxetic Foam in Sports Helmets

Directory of Open Access Journals (Sweden)

Leon Foster

2018-03-01

Full Text Available This investigation explored the viability of using open cell polyurethane auxetic foams to augment the conformable layer in a sports helmet and improve its linear impact acceleration attenuation. Foam types were compared by examining the impact severity on an instrumented anthropomorphic headform within a helmet consisting of three layers: a rigid shell, a stiff closed cell foam, and an open cell foam as a conformable layer. Auxetic and conventional foams were interchanged to act as the helmet’s conformable component. Attenuation of linear acceleration was examined by dropping the combined helmet and headform on the front and the side. The helmet with auxetic foam reduced peak linear accelerations (p < 0.05 relative to its conventional counterpart at the highest impact energy in both orientations. Gadd Severity Index reduced by 11% for frontal impacts (38.9 J and 44% for side impacts (24.3 J. The conformable layer within a helmet can influence the overall impact attenuating properties. The helmet fitted with auxetic foam can attenuate impact severity more than when fitted with conventional foam, and warrants further investigation for its potential to reduce the risk of traumatic brain injuries in sport specific impacts.

Patients, as well as the broader society, trust that health care practitioners who have been granted authority by the state to provide safe and beneficial health care are competent to do so. Recent instances where patients have been harmed as the result of treatment that fell below the accepted standard of competence have negatively impacted on trust. As the state has a responsibility to protect the public from this type of harm, legislation that mandates reporting of certain instances where the behaviour of health care professionals has fallen below the acceptable standard has been introduced. While this may have been designed to restore public trust, this article argues that it has the potential to diminish trust on the basis that mandatory reporting may be equivalent to mandatory whistleblowing.

The purpose was to compare head kinematics between the Eject Helmet Removal System and manual football helmet removal. This quasi-experimental study was conducted in a controlled laboratory setting. Thirty-two certified athletic trainers (sex, 19 male and 13 female; age, 33 ± 10 years; height, 175 ± 12 cm; mass, 86 ± 20 kg) removed a football helmet from a healthy model under 2 conditions: manual helmet removal and Eject system helmet removal. A 6-camera motion capture system recorded 3-dimensional head position. Our outcome measures consisted of the average angular velocity and acceleration of the head in each movement plane (sagittal, frontal, and transverse), the resultant angular velocity and acceleration, and total motion. Paired-samples t tests compared each variable across the 2 techniques. Manual helmet removal elicited greater average angular velocity in the sagittal and transverse planes and greater resultant angular velocity compared with the Eject system. No differences were observed in average angular acceleration in any single plane of movement; however, the resultant angular acceleration was greater during manual helmet removal. The Eject Helmet Removal System induced greater total head motion. Although the Eject system created more motion at the head, removing a helmet manually resulted in more sudden perturbations as identified by resultant velocity and acceleration of the head. The implications of these findings relate to the care of all cervical spine-injured patients in emergency medical settings, particularly in scenarios where helmet removal is necessary.

Full Text Available In this study the ballistic limit of a steel helmet against a FMJ 919 mm caliber bullet is estimated. The helmet model is the typical polish helmet wz.31.The helmet material showed high strength low alloy steel material of 0.28 carbon content and 9.125 kgm2 areal density. The tensile test according to ASTM E8 showed a tensile strength of 1236.4 MPa .The average hardness value was about HV550. First shooting experiment has been executed using a 9 mm pistol based on 350 ms muzzle velocity at 5m against the simply supported helmet complete penetrations rose in this test were in the form of cracks on the helmet surface and partial penetrations were in the form of craters on the surface whose largest diameter and depth were 43 mm and 20.2 mm consequently .The second experiment was on a rifled gun arrangement 13 bullets of 919 mm caliber were shot on the examined simply supported steel helmet at a zero obliquity angle at different velocities to determine the ballistic limit velocity V50 according to MIL-STD-662F. Three major outcomes were revealed 1 the value V50 which found to be about 390 ms is higher than the one found in literature 360 ms German steel helmet model 1A1. 2 The smallest the standard deviation of the mixed results zone data the most accurate the ballistic limit is. 3Similar to the performance of blunt-ended projectiles impacting overmatching targets tD near 11 or larger It was found that the dominating failure mode of the steel helmet stuck by a hemispherical-nose projectile was plugging mode despite of having tD ratio of about 19 undermatching.

The incidence and cost of motorcycle accidents are projected to increase. Motorcycle helmets are accepted as an effective strategy for reducing the morbidity and therefore the cost of motorcycle accidents. Despite this, states have continued to repeal helmet laws in the past 20 years. In addition, variations in the methodologies and outcomes of published reports have contributed to uncertainty regarding the health care dollars saved due to motorcycle helmet use. The purpose of this systematic review and meta-analysis is to clarify the economic impact of motorcycle helmet use. Our primary source was Medline. Search terms included "motorcycle," "motorbike," "motorcycle helmet," "head protective devices," and "cost and cost analysis." The review only included articles that were primary studies, written in English, evaluations of periods after 1994, and published in a peer-reviewed journal. Two independent authors extracted data using predefined data fields. Meta-analysis was done using the R-metafor package. Twelve papers met the criteria for inclusion. Meta-analysis demonstrated that nonhelmeted patients required $12,239 more in hospital costs per patient. Nonhelmeted patients also required more postdischarge care and were more likely to use publicly funded insurance. Studies also found lower injury severity and better hospital course in the helmeted population. Study limitations included selection bias, unclear statistical assumptions, lack of precision measures, confounding variables, and lack of standardization to a common year. Meta-analysis demonstrated an I2 of 67%, attributing a significant proportion of outcome variation to study differences. Motorcycle helmet use reduces morbidity and contributes to significant health care cost savings. Continuing antihelmet legislation will impose a substantial economic burden to the health care system, the government, and the public.

Evaluation of the mandatory construction induction training program in Western Australia: unanticipated consequences.

Science.gov (United States)

Bahn, Susanne; Barratt-Pugh, Llandis

2012-08-01

Since January 1, 2007, Government legislation in Western Australia required all workers in construction to complete mandatory safety awareness training before they began work on site. During the implementation of this new legislation there was considerable resistance from the construction sector due to the mandatory nature of the training. The construction industry viewed this as an unnecessary impost as they considered that there was already sufficient safety training delivered through individual company and site inductions. In 2010, we evaluated the new Construction Induction Training (CIT) in the commercial construction sector in Western Australia to find that since 2007 there has been an unanticipated change in support for the mandatory training. The 2010 study shows a shift in the values of the safety culture for the commercial sector of the construction industry. In 2010, the industry not only supports the mandatory CIT, but is very vocal in its request to re-institute the refresher courses that were withdrawn in 2009. Indeed, 79% of respondents claimed there were measurable benefits to their business having their employees complete the CIT, while 96% claimed the CIT assisted in reducing accidents/incidents on their worksites. This 2010 study indicates that in this case, mandatory training has had a positive effect on safety culture change and gradually reduced work-related injury in the industry since 2007 to the present. The paper uses data from two studies conducted in 2006 and 2010 to highlight the unanticipated change in perception of the value of mandatory safety training in the WA construction industry to one which is positive and supportive.

Schieber, R A; Gilchrist, J; Sleet, D A

2000-01-01

Laws and regulations are among the most effective mechanisms for getting large segments of the population to adopt safety behaviors. These have been applied at both the state and federal levels for diverse injury issues. Certain legal actions are taken to prevent the occurrence of an otherwise injury-producing event, while other legal actions are designed to prevent injury once an event has occurred. At the federal level, effective laws and regulations have been directed at dangers posed by unsafe manufactured products or motor vehicle design. At the state level, effective safety laws and regulations have been directed at encouraging safety behaviors and regulating the use of motor vehicles or other forms of transportation. In this article, six legislative efforts are described to point out pros and cons of the legislative approach to promoting safety. Three such efforts are aimed at preventing injury-producing events from occurring: mandating child-resistant packaging for prescription drugs and other hazardous substances, regulating tap water temperature by presetting a safe hot-water heater temperature at the factory, and graduated licensing. Three other examples illustrate the value and complexities of laws designed to prevent injuries once an injury-producing event does occur: mandatory bicycle helmet use, sleep-wear standards, and child safety seat use. This article concludes with specific recommendations, which include assessing the value of laws and regulations, preventing the rescission of laws and regulations known to work, refining existing laws to eliminate gaps in coverage, developing regulations to adapt to changing technology, exploring new legal means to encourage safe behavior, and increasing funding for basic and applied research and community programs. Further reductions in childhood injury rates will require that leaders working in the field of injury prevention together provide the creativity to devise new safety devices and programs, incentives

Helmet use reduces mortality risk for motorcyclists, regardless of drug and alcohol use. However, the association between drug use and motorcycle helmet utilization is not well known. This study examines the relationship between drug use and motorcycle helmet use among fatally injured motorcycle riders. Using data from the 2005-2009 Fatality Analysis Reporting System (FARS), we examined the association between drug use and motorcycle helmet use in a multivariable logistic regression analysis of 9861 fatally injured motorcycle riders in the United States. For fatally injured motorcycle riders, use of alcohol, marijuana, or other drugs was associated with increased odds of not wearing a motorcycle helmet, controlling for the effects of state motorcycle helmet laws and other confounding variables. Predicted probabilities indicate that helmet use substantially decreases among fatally injured riders mixing alcohol with marijuana and other drugs. Furthermore, the likelihood of helmet use between marijuana-only users and other drug users is virtually the same across all blood alcohol content (BAC) levels. This study provides evidence that alcohol, marijuana, and other drug use is associated with not wearing a motorcycle helmet in fatal motorcycle crashes. There is a clear need for additional prevention and intervention efforts that seek to change helmet and drug use norms among motorcycle riders.

Differential protective effects of motorcycle helmets against head injury.

Science.gov (United States)

Singleton, Michael D

2017-05-19

Although numerous observational studies have demonstrated a protective effect of motorcycle helmets against head injury, the degree of protection against specific head injury types remains unclear. Experimental biomechanics studies involving cadavers, animals, and computer models have established that head injuries have varying etiologies. This retrospective cross-sectional study compared helmet protection against skull fracture, cerebral contusion, intracranial hemorrhage, and cerebral concussion in a consecutive series of motorcycle operators involved in recent traffic crashes in Kentucky. Police collision reports linked to hospital inpatient and emergency department (ED) claims were analyzed for the period 2008 to 2012. Motorcycle operators with known helmet use who were not killed at the crash scene were included in the study. Helmet use was ascertained from the police report. Skull fracture, cerebral contusion, intracranial hemorrhage, and cerebral concussion were identified from International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes on the claims records. The relative risks of each type of head injury for helmeted versus unprotected operators were estimated using generalized estimating equations. Helmets offer substantial protection against skull fracture (relative risk [RR] = 0.31, 95% confidence interval [CI], 0.23, 0.34), cerebral contusion (RR = 0.29, 95% CI, 0.16, 0.53), and intracranial hemorrhage (RR = 0.47, 95% CI, 0.35, 0.63). The findings pertaining to uncomplicated concussion (RR = 0.80, 95% CI, 0.64, 1.01) were inconclusive. A modest protective effect (20% risk reduction) was suggested by the relative risk estimate, but the 95% confidence interval included the null value. Motorcycle helmets were associated with a 69% reduction in skull fractures, 71% reduction in cerebral contusion, and 53% reduction in intracranial hemorrhage. This study finds that current motorcycle helmets do not protect equally against

External compression headache is defined as a headache caused by an external physical compression applied on the head. It affects about 4% of the general population; however, certain populations (e.g. construction workers and military personnel) with particular needs of headwear or helmet are at higher risk of developing this type of headache. External compression headache is poorly studied in relation to specific populations. This study aimed to investigate the prevalence and pattern of helmet-induced external compression headache among Danish military personnel of the Northern Jutland region in Denmark. Data acquisition was based on a custom-made questionnaire delivered to volunteers who used helmets in the Danish military service and who agreed to participate in this study. The military of the Northern Jutland region of Denmark facilitated recruitment of the participants. The questionnaires were delivered on paper and the collected (anonymous) answers (total 279) were used for further analysis. About 30% of the study participants reported headache in relation to wearing a military helmet. Headache was defined as a pressing pain predominantly in the front of the head with an average intensity of 4 on a visual analogue scale of 0 (no pain) to 10 (worst pain imaginable). It was also found that helmets with different designs influenced both the occurrence of headache and its characteristics. This study is the first to demonstrate the prevalence and pattern of compression headache among military personnel in North Jutland, Denmark. The findings of this study call for further attention to helmet-induced external compression headache and strategies to minimize the burden.

Motorcycle crashes account for a disproportionate number of motor vehicle deaths and injuries in the U.S. Motorcycle helmet use can lead to an estimated 42% reduction in risk for fatal injuries and a 69% reduction in risk for head injuries. However, helmet use in the U.S. has been declining and was at 60% in 2013. The current review examines the effectiveness of motorcycle helmet laws in increasing helmet use and reducing motorcycle-related deaths and injuries. Databases relevant to health or transportation were searched from database inception to August 2012. Reference lists of reviews, reports, and gray literature were also searched. Analysis of the data was completed in 2014. A total of 60 U.S. studies qualified for inclusion in the review. Implementing universal helmet laws increased helmet use (median, 47 percentage points); reduced total deaths (median, -32%) and deaths per registered motorcycle (median, -29%); and reduced total injuries (median, -32%) and injuries per registered motorcycle (median, -24%). Repealing universal helmet laws decreased helmet use (median, -39 percentage points); increased total deaths (median, 42%) and deaths per registered motorcycle (median, 24%); and increased total injuries (median, 41%) and injuries per registered motorcycle (median, 8%). Universal helmet laws are effective in increasing motorcycle helmet use and reducing deaths and injuries. These laws are effective for motorcyclists of all ages, including younger operators and passengers who would have already been covered by partial helmet laws. Repealing universal helmet laws decreased helmet use and increased deaths and injuries. Published by Elsevier Inc.

Measurement of Gamma Knife registered helmet factors using MOSFETs

International Nuclear Information System (INIS)

Kurjewicz, Laryssa; Berndt, Anita

2007-01-01

The relative dose rate for the different Gamma Knife registered helmets (4, 8, 14, and 18 mm) is characterized by their respective helmet factors. Since the plateau of the dose profile for the 4 mm helmet is at most 1 mm wide, detector choices are limited. Traditionally helmet factors have been measured using 1x1x1 mm 3 thermoluminescent dosimeters (TLDs). However, these are time-consuming, cumbersome measurements. This article investigates the use of metal-oxide-semiconductor field effect transistors (MOSFETs) (active area of 0.2x0.2 mm 2 ) as a more accurate and convenient dosimeter. Their suitability for these measurements was confirmed by basic characterization measurements. Helmet factors were measured using both MOSFETs and the established TLD approach. A custom MOSFET cassette was designed in analogy to the Elekta TLD cassette (Elekta Instruments AB) for use with the Elekta dosimetry sphere. Although both dosimeters provided values within 3% of the manufacturer's suggestion, MOSFETs provided superior accuracy and precision, in a fraction of the time required for the TLD measurements. Thus, MOSFETs proved to be a reasonable alternative to TLDs for performing helmet factor measurements

Although helmet use has been compulsory for motorcycle drivers and passengers in Thailand since the enactment of the Helmet Act in 1994, recent surveys show that the prevalence of helmet usage remains low, particularly among passengers. This paper has sought to explore motorcyclists' awareness of helmet law enforcement in Thailand and examine whether it affects their helmet use behaviour. A total of 2,429 drivers and 1,328 passengers in urban cities nationwide were interviewed in 2009, and the data were analysed using a multivariate ordered logit regression technique. About 60% of the drivers and only 28% of the passengers reported that they always wore a motorcycle helmet. Apart from basic demographics (i.e. age and gender) and riding frequency, our analysis reveals that the awareness of helmet law enforcement was among the contributing factors influencing the use of motorcycle helmets in Thailand. Regardless of riding position, the prevalence of helmet use tended to be greater among those frequently observing the police's checkpoints for helmet wearing and those perceiving the high risk of being caught for non-helmet use. However, the use of helmets appeared to be lower among drivers who perceived the checkpoints to take place at the same times and locations, which were likely predicted. For motorcycle passengers, it was found that the low prevalence of helmet use was potentially attributable to the absence of knowledge on the compulsory helmet law for passengers and the perception that the law was not enforced by the police. Thus, if motorcycle helmet use in Thailand is to be increased, considerable efforts need to be given to increasing the perceived risk of apprehension for non-helmet use (e.g. more police presence and random scheduling of enforcement activities), improving the awareness of the existing helmet law for passengers, and ensuring that helmet wearing by passengers is more strictly enforced.

Doglioni, N; Micaglio, M; Zanardo, V; Trevisanuto, D

2009-12-01

In a recent short-term physiological study, we demonstrated a new continuous positive airway pressure (CPAP) system (neonatal helmet-CPAP) that could be a feasible device for managing preterm infants needing continuous distending pressure with better tolerability than nasal-CPAP. However, its application for a long-term period has never been reported in neonates. Here, we describe the use of neonatal helmet-CPAP in a neonate with persistent pulmonary hypertension of the newborn. Twenty minutes after neonatal helmet-CPAP placement, the baseline post-ductal tcSaO2 (66%) and alveolar-arterial gradient O2 improved from 66% and 648 mmHg to 100% and 465 mmHg, respectively. The neonatal helmet-CPAP was applied for 48 hours and was well-tolerated by the patient without complications. Long-term use of neonatal helmet-CPAP appears feasible and well-tolerated. Comparative trials are needed.

To compare the Eject Helmet Removal (EHR) System with manual football helmet removal. This quasiexperimental counterbalanced study was conducted in a controlled laboratory setting. Thirty certified athletic trainers (17 men and 13 women; mean ± standard deviation age: 33.03 ± 10.02 years; height: 174.53 ± 12.04 cm; mass: 85.19 ± 19.84 kg) participated after providing informed consent. Participants removed a Riddell Revolution IQ football helmet from a healthy model two times each under two conditions: manual helmet removal (MHR) and removal with the EHR system. A six-camera, three-dimensional motion capture system was used to record range of motion (ROM) of the head. A digital stopwatch was used to time trials and to record a split time associated with EHR system bladder insertion. A modified Borg CR10 scale was used to measure the rating of perceived exertion (RPE). Mean values were created for each variable. Three pairwise t-tests with Bonferroni-corrected alpha levels tested for differences between time for removal, split time, and RPE. A 2 x 3 (condition x plane) totally within-subjects repeated-measures design analysis of variance (ANOVA) tested for differences in head ROM between the sagittal, frontal, and transverse planes. Analyses were performed using SPSS (version 18.0) (alpha = 0.05). There was no statistically significant difference in perceived difficulty between EHR (RPE = 2.73) and MHR (RPE = 2.55) (t(29) = 0.76; p = 0.45; d = 0.20). Manual helmet removal was, on average, 28.95 seconds faster than EHR (t(29) = 11.44; p football helmets and in helmets used in other sports such as lacrosse, motorsports, and ice hockey.

Aircrew helmet design and manufacturing enhancements through the use of advanced technologies

Cadogan, David P.; George, Alan E.; Winkler, Edward R.

1993-12-01

With the development of helmet mounted displays (HMD) and night vision systems (NVS) for use in military and civil aviation roles, new methods of helmet development need to be explored. The helmet must be designed to provide the user with the most lightweight, form fitting system, while meeting other system performance requirements. This can be achieved through a complete analysis of the system requirements. One such technique for systems analysis, a quality function deployment (QFD) matrix, is explored for this purpose. The advanced helmet development process for developing aircrew helmets includes the utilization of several emerging technologies such as laser scanning, computer aided design (CAD), computer generated patterns from 3-D surfaces, laser cutting of patterns and components, and rapid prototyping (stereolithography). Advanced anthropometry methods for helmet development are also available for use. Besides the application of advanced technologies to be used in the development of helmet assemblies, methods of mass reduction are also discussed. The use of these advanced technologies will minimize errors in the development cycle of the helmet and molds, and should enhance system performance while reducing development time and cost.

Louisiana motorcycle fatalities in the wake of governmentally implemented change: a retrospective analysis of the motorcycle morbidity and mortality before, during, and after the repeal of a statewide helmet mandate.

2013-06-01

On August 15, 2004, Louisiana's universal motorcycle helmet mandate was reinstated. Previous studies have shown that mortality and morbidity of motorcycle riders who crashed had increased during the 5 years the mandate was repealed. The objective of this study was to discern whether the reinstatement of the universal helmet mandate has resulted in a subsequent decrease in motorcycle-related mortality and morbidity in the state of Louisiana. A retrospective analysis was performed observing the regularity of helmet use and the associated morbidity and mortality of motorcycle traffic accidents from the time before, during, and after the universal motorcycle helmet mandate was repealed in the state of Louisiana. Fatality statistics were obtained through the National Highway Safety Traffic Association. Injury, helmet use, and collision data were obtained from the Louisiana Highway Safety Commission. Motorcycle registration data were obtained from the Federal Highway Administration. Motorcycle crash-related fatalities increased significantly when the statewide helmet mandate was repealed, and interestingly, after reinstatement, these fatality rates never returned to their previous lows. Motorcycle fatalities have increased out of proportion to the increase in motorbike registrations, even when yearly fatalities are normalized to fatalities per 10,000 registered bikes. An all-time high in fatalities was seen in 2006, a year subsequent to the mandate's reinstatement. Fatalities per collision were elevated significantly after the mandate's repeal but did not return to prerepeal lows after the mandate's reinstatement. Although helmet use after reinstatement has reached all-time highs, fatality rates have remained elevated since the original mandate repeal in 1999. Other achievable changes in state policy and law enforcement should be explored to quell this heightened risk to motorcycle enthusiasts in Louisiana, and states considering changing their own motorcycle helmet

Nano-Composite Foam Sensor System in Football Helmets.

American football has both the highest rate of concussion incidences as well as the highest number of concussions of all contact sports due to both the number of athletes and nature of the sport. Recent research has linked concussions with long term health complications such as chronic traumatic encephalopathy and early onset Alzheimer's. Understanding the mechanical characteristics of concussive impacts is critical to help protect athletes from these debilitating diseases and is now possible using helmet-based sensor systems. To date, real time on-field measurement of head impacts has been almost exclusively measured by devices that rely on accelerometers or gyroscopes attached to the player's helmet, or embedded in a mouth guard. These systems monitor motion of the head or helmet, but do not directly measure impact energy. This paper evaluates the accuracy of a novel, multifunctional foam-based sensor that replaces a portion of the helmet foam to measure impact. All modified helmets were tested using a National Operating Committee Standards for Athletic Equipment-style drop tower with a total of 24 drop tests (4 locations with 6 impact energies). The impacts were evaluated using a headform, instrumented with a tri-axial accelerometer, mounted to a Hybrid III neck assembly. The resultant accelerations were evaluated for both the peak acceleration and the severity indices. These data were then compared to the voltage response from multiple Nano Composite Foam sensors located throughout the helmet. The foam sensor system proved to be accurate in measuring both the HIC and Gadd severity index, as well as peak acceleration while also providing additional details that were previously difficult to obtain, such as impact energy.

Capabilities of Helmets for Preventing Head Injuries Induced by Ballistic Impacts

Directory of Open Access Journals (Sweden)

2004-01-01

Full Text Available The limiting performance of ballistically loaded helmets designed to reduce head injuries is studied analytically. The projectile does not penetrate the helmet. This analysis evaluates the absolute minimum of the peak displacement of the helmet shell relative to the head, provided that criteria measuring the severity of head injuries lie within prescribed limits. Rather than optimize a specific design configuration, e.g. a viscoelastic foam liner, characteristics of a time-dependent force representing the helmet liner are calculated. The formulation reduces the limiting performance analysis to an optimal control problem.

There is limited information on the relationship between football helmet fit and concussion severity. Poor helmet fit may predispose football players to a more severe concussion. Descriptive epidemiology study. Level 3. Data from concussion injury reports were obtained from the National High School Sports-Related Injury Surveillance System over a 9-year period. Symptoms, duration, and helmet parameters (fit, interior padding) were analyzed for all first-time concussions. Data from 4580 concussions were analyzed. Patients who suffered concussions with a helmet that did not fit properly (3.22%), as determined by an athletic trainer, had higher rates of drowsiness (RR, 1.46; P = 0.005), hyperexcitability (RR, 2.38; P = 0.047), and sensitivity to noise (RR, 1.88; P football helmet is a risk factor for a concussion with more symptoms and of longer duration. Concussions of longer duration are also more common in players with an air bladder-lined helmet. Current high school football rules should mandate supervision and maintenance of helmet fit throughout the season, prior to impact. Team physicians, athletic trainers, coaches, and high school officials should ensure proper oversight of helmet fit in high school athletes to decrease concussion severity and duration. © 2016 The Author(s).

Noise-Canceling Helmet Audio System

Science.gov (United States)

Seibert, Marc A.; Culotta, Anthony J.

2007-01-01

A prototype helmet audio system has been developed to improve voice communication for the wearer in a noisy environment. The system was originally intended to be used in a space suit, wherein noise generated by airflow of the spacesuit life-support system can make it difficult for remote listeners to understand the astronaut s speech and can interfere with the astronaut s attempt to issue vocal commands to a voice-controlled robot. The system could be adapted to terrestrial use in helmets of protective suits that are typically worn in noisy settings: examples include biohazard, fire, rescue, and diving suits. The system (see figure) includes an array of microphones and small loudspeakers mounted at fixed positions in a helmet, amplifiers and signal-routing circuitry, and a commercial digital signal processor (DSP). Notwithstanding the fixed positions of the microphones and loudspeakers, the system can accommodate itself to any normal motion of the wearer s head within the helmet. The system operates in conjunction with a radio transceiver. An audio signal arriving via the transceiver intended to be heard by the wearer is adjusted in volume and otherwise conditioned and sent to the loudspeakers. The wearer s speech is collected by the microphones, the outputs of which are logically combined (phased) so as to form a microphone- array directional sensitivity pattern that discriminates in favor of sounds coming from vicinity of the wearer s mouth and against sounds coming from elsewhere. In the DSP, digitized samples of the microphone outputs are processed to filter out airflow noise and to eliminate feedback from the loudspeakers to the microphones. The resulting conditioned version of the wearer s speech signal is sent to the transceiver.

The rate of head injury is 1.86-6 times higher for snowboarding than for skiing. Detailed data about the usefulness of a helmet or knit cap for protecting against serious head injuries have not been reported. The present study evaluated the use of a helmet or knit cap for preventing head injuries. Questionnaire data were collected from 1,190 consecutive patients in a hospital during the 1999/2000-2002/2003 winter seasons at Uonuma ski resort, Niigata, Japan. Patients were divided into the helmet, knit cap, and no cap groups. Upper technical level was highest and jumping as the cause of injury was most frequent in the helmet group. After adjustment for other confounders, there was a significant negative association between the occurrence of serious head injury during snowboarding and female sex (adjusted odds ratio 0.55, 95% confidence interval 0.421-0.718, p jumping (adjusted odds ratio 2.25, 95% confidence interval 1.48-3.43, p = 0.0001). Among snowboarding maneuvers, only jumping showed a significant negative association between wearing of a helmet or knit cap and the occurrence of serious head injury (p = 0.036). Snowboarders who wear helmets might attempt dangerous maneuvers causing injuries. Wearing of a helmet or knit cap protected against serious head injuries on jumping. Every snowboarder should wear a helmet or knit cap on jumping to prevent head injury.

There is greater attention to head-related injuries and concussions in American football. The helmet's structural safety and the way that football players use their helmets are important in preventing head injuries. Current strategies include penalizing players for high-risk behavior such as leading with their helmet or hitting an opposing player above the shoulder. Passive strategies include helmet modification to better protect the head of the players or to change the playing style of the players. Hawai'i high school varsity football players were surveyed to determine how they use their helmets and how a new helmet design would affect their style of play. One hundred seventy-seven surveys were completed; 79% said that they used their helmet to hit an opposing player during a tackle and 46% said they made this contact intentionally. When asked about modifying helmets with a soft material on the outside, 48% said they thought putting a soft cover over a regular helmet would protect their head better. However, many participants said that putting a soft cover over their regular helmet was a bad idea for various reasons. Most young football players use their helmets to block or tackle despite being taught they would be penalized or potentially injured if they did so. By gaining a better understanding of why and how players use their helmets and how they would respond to new helmet designs, steps can be taken to reduce head injuries for all levels of play.

1981-07-01

Measurements of the at-ear helmet-generated aerodynamic noise and helmet insertion loss were carried out for the two major types of motorcycle helmets. From these data and existing information on noise generation by flow around a bare head it was found that for quiet motorcycles at typical operating speeds a significant part of the riders at-ear noise is generated by the air flow. An assessment of the possibility of hearing damage was then carried out. It was found that only with extremely high usage would there be a significant risk of hearing damage for either the bare headed or helmeted rider. Helmets did, however, give significant protection. Detection of warning signals was then considered. It was found that under none of the conditions investigated here did the helmet put its wearer at a disadvantage compared with the bare headed rider, and at typical constant speeds the helmet gave a rider an advantage in the detection of warning signals.

The pocketing effect of helmet padding helps to dissipate forces experienced by the head, but if the player's helmet remains stationary in an opponent's shoulder pads, the compressive force on the cervical spine may increase. To (1) measure the coefficient of static friction between different football helmet finishes and football jersey fabrics and (2) calculate the potential amount of force on a player's helmet due to the amount of friction present. Cross-sectional study. Laboratory. Helmets with different finishes and different football jersey fabrics. The coefficient of friction was determined for 2 helmet samples (glossy and matte), 3 football jerseys (collegiate, high school, and youth), and 3 types of jersey numbers (silkscreened, sublimated, and stitched on) using the TAPPI T 815 standard method. These measurements determined which helmet-to-helmet, helmet-to-jersey number, and helmet-to-jersey material combination resulted in the least amount of static friction. The glossy helmet versus glossy helmet combination produced a greater amount of static friction than the other 2 helmet combinations (P = .013). The glossy helmet versus collegiate jersey combination produced a greater amount of static friction than the other helmet-to-jersey material combinations (P < .01). The glossy helmet versus silkscreened numbers combination produced a greater amount of static friction than the other helmet-to-jersey number combinations (P < .01). The force of static friction experienced during collisions can be clinically relevant. Conditions with higher coefficients of static friction result in greater forces. In this study, the highest coefficient of friction (glossy helmet versus silkscreened number) could increase the forces on the player's helmet by 3553.88 N when compared with other helmet-to-jersey combinations. Our results indicate that the makeup of helmet and uniform materials may affect sport safety.

Concussion in American football is a prevalent concern. Research has been conducted examining frequencies, location, and thresholds for concussion from impacts. Little work has been done examining how impact location may affect risk of concussive injury. The purpose of this research was to examine how impact site on the helmet and type of impact, affects the risk of concussive injury as quantified using finite element modelling of the human head and brain. A linear impactor was used to impact a helmeted Hybrid III headform in several locations and using centric and non-centric impact vectors. The resulting dynamic response was used as input for the Wayne State Brain Injury Model to determine the risk of concussive injury by utilizing maximum principal strain as the predictive variable. The results demonstrated that impacts that occur primarily to the side of the head resulted in higher magnitudes of strain in the grey and white matter, as well as the brain stem. Finally, commonly worn American football helmets were used in this research and significant risk of injury was incurred for all impacts. These results suggest that improvements in American football helmets are warranted, in particular for impacts to the side of the helmet.

The aim of this study was to assess helmet use and associated factors among motorcycle riders during Songkran festival in Thailand. A cross-sectional survey was conducted to determine the prevalence of helmet use among Thai motorcycle riders (sample size = 18,998) during four days of the Songkran festival. For this sample, the population of motorcycle riders was consecutively selected using quota sampling from 12 petrol stations in four provinces from each of the four main geographical regions of Thailand. The study was conducted at petrol stations at roads in town, outside town and highway at different time intervals when trained field staff administered a structured questionnaire and performed an observation checklist. Results indicate that 44.2% of the motorcycle riders and 72.5% of the motorcycle passengers had not been using a helmet. In multivariable analysis demographics, environmental factors, helmet use experiences and attitudes and recalling a lower exposure to road safety awareness (RSA) campaign were associated with non-helmet use among motorcyclists. It appears that the RSA campaign may have some positive effect on reducing non-helmet use among motorcycle riders during the Songkran festival. PMID:23202686

Background: There is limited information on the relationship between football helmet fit and concussion severity. Hypothesis: Poor helmet fit may predispose football players to a more severe concussion. Study Design: Descriptive epidemiology study. Level of Evidence: Level 3. Methods: Data from concussion injury reports were obtained from the National High School Sports-Related Injury Surveillance System over a 9-year period. Symptoms, duration, and helmet parameters (fit, interior padding) were analyzed for all first-time concussions. Results: Data from 4580 concussions were analyzed. Patients who suffered concussions with a helmet that did not fit properly (3.22%), as determined by an athletic trainer, had higher rates of drowsiness (RR, 1.46; P = 0.005), hyperexcitability (RR, 2.38; P = 0.047), and sensitivity to noise (RR, 1.88; P < 0.001); had more symptoms (5.34 vs 4.54, P = 0.004); and had longer symptom duration (P = 0.04). Athletes with helmets lined with an air bladder had greater rates of sensitivity to light (RR, 1.13; P = 0.02), sensitivity to noise (RR, 1.25; P = 0.009), and longer symptom duration (P = 0.004) compared with foam or gel liners. Conclusion: An improperly fitted football helmet is a risk factor for a concussion with more symptoms and of longer duration. Concussions of longer duration are also more common in players with an air bladder–lined helmet. Current high school football rules should mandate supervision and maintenance of helmet fit throughout the season, prior to impact. Clinical Relevance: Team physicians, athletic trainers, coaches, and high school officials should ensure proper oversight of helmet fit in high school athletes to decrease concussion severity and duration.

A helmet can reduce head accident severity. The aim of this research study was to study the intention for helmet use of students who ride motorcycles in Vietnam, by Structural Equation Modeling (SEM). Questionnaires developed by several traffic psychology modules, including the Theory of Planned Behaviour (TPB), Traffic Locus of Control (T-LOC), and Health Belief Model (HBM), were distributed to students at Ton Thang University and University of Architecture, Ho Chi Minh City. SEM was used to explain helmet use behaviour. The results indicate that TPB, T-LOC and HBM could explain the variance in helmet use behaviour. However, TPB can explain behaviour (helmet use intention) better than T-LOC and HBM. The outcome of this study is useful for the agencies responsible to improve motorcycle safety.

The GPK protective helmet with an integrated respirator system protecting a miner's respiratory system and eyes from gases and dusts is described. The system uses compressed air from the mine compressed air system. Air is supplied to the respirator by an elastic rubber pipe to 30 m long. The air cools the miner's head under the helmet and passes between a protective shield and the miner's face protecting eyes and the respiratory system. Air supply ranges from 100 to 150 l/min. The air supplied to the respirator is cleaned by a filter. The GPK system weighs 1.2 kg. The system has been tested under laboratory conditions and in two coal mines under operational conditions at longwall faces and during mine drivage. Tests showed that the GPK guarantees efficient cooling and protection from dust. Design of the GPK helmet with a respirator is shown in two schemes. Technical specifications of the system are given.

Williams, B. A.; Shitzer, A.

1974-01-01

A modular liquid-cooled helmet liner made of eight form-fitting neoprene patches was constructed. The liner was integrated into the sweatband of an Army SPH-4 helicopter aircrew helmet. This assembly was tested on four subjects seated in a hot (47 C), humid (40%) environment. Results indicate a marked reduction in the rate of increase of physiological body functions. Rectal temperature, weight loss, heart rate, and strain indices are all reduced to approximately 50% of uncooled levels. The cooling liner removed from 10% to 30% of total metabolic heat produced. This study also demonstrated the technical feasilibity of using a cooling liner in conjunction with a standard hard helmet. Potential applications of the cooling liner in thermally stressful environments are numerous, notably for helicopter and other aircrews.

Motorcyclists' injuries and fatalities are a major public health concern in many developing countries including Ghana. This study therefore aimed to investigate the prevalence of helmet use among motorcyclists in Wa, Ghana. The method used involved a cross-sectional roadside observation at 12 randomly selected sites within and outside the CBD of Wa. A total of 14,467 motorcyclists made up of 11,360 riders and 3107 pillion riders were observed during the study period. Most observed riders (86.5%) and pillion riders (61.7%) were males. The overall prevalence of helmet use among the observed motorcyclists was 36.9% (95% CI: 36.1-37.7). Helmet use for riders was 45.8% (95% CI: 44.8-46.7) whilst that for pillion riders was 3.7% (95 CI: 3.0-4.4). Based on logistic regression analysis, higher helmet wearing rates were found to be significantly associated with female gender, weekdays, morning periods and at locations within the CBD. Riders at locations outside the CBD were about 7 times less likely to wear a helmet than riders within the CBD (48.9% compared to 42.3%; χ(2)(1)=49.526; plegislation that mandates the use of helmets by both riders and pillion riders on all roads in Ghana, helmet use is generally low in Wa. This suggests that all stakeholders in road safety should jointly intensify education on helmet use and pursue rigorous enforcement on all road types especially at locations outside the CBD to improve helmet use in Wa.

2008-02-01

The helmet-mounted equipment worn by military pilots increases the weight of the helmet system and shifts its center of gravity, increasing the loads on neck structures, especially during acceleration. The aim of this study was to determine neck muscle strain with different head-loads during trampoline-induced G loads (0 to +4 G). Under three conditions [no helmet, helmet, helmet with night vision goggles (NVG)], 14 subjects performed trampoline exercises including basic, hand-and-knee, and back bouncing. EMG activity was measured for the sternocleidomastoid (SCM), cervical erector spinae (CES), trapezoid (TRA), and thoracic erector spinae (TES) muscles. Muscle strain was determined as a percentage of maximal voluntary contraction (%MVC). For the three exercises combined, the following significant changes were found: compared to control, the helmet increased muscle strain by 18%, 28%, and 18% in the SCM, CES, and TRA, respectively; NVG produced a further increase of 11% in the SCM and 6% in the CES. During back bouncing, the helmet increased muscle strain by 14% in the SCM and 19% in the CES, and NVG further increased this strain by 14% in the SCM. Hand-and-knee bouncing loaded extensors: the helmet caused increases of 46% in the CES and 29% in the TES, while NVG produced a further 13% increase in CES activation. Helmet weight alone had a large effect on muscular workload. The additional frontal weight of the NVG caused a further increase in the activity of cervical muscles that were already subjected to high strain.

Injuries of the head from backface deformation of ballistic protective helmets under ballistic impact.

Modern ballistic helmets defeat penetrating bullets by energy transfer from the projectile to the helmet, producing helmet deformation. This deformation may cause severe injuries without completely perforating the helmet, termed "behind armor blunt trauma" (BABT). As helmets become lighter, the likelihood of larger helmet backface deformation under ballistic impact increases. To characterize the potential for BABT, seven postmortem human head/neck specimens wearing a ballistic protective helmet were exposed to nonperforating impact, using a 9 mm, full metal jacket, 124 grain bullet with velocities of 400-460 m/s. An increasing trend of injury severity was observed, ranging from simple linear fractures to combinations of linear and depressed fractures. Overall, the ability to identify skull fractures resulting from BABT can be used in forensic investigations. Our results demonstrate a high risk of skull fracture due to BABT and necessitate the prevention of BABT as a design factor in future generations of protective gear. © 2014 American Academy of Forensic Sciences.

Full Text Available Objectives: The aim of the study was to investigate whether a ski helmet interferes with the sound localization and the time of sound perception in the frontal plane. Material and Methods: Twenty-three participants (age 30.7±10.2 were tested on the slope in 2 conditions, with and without wearing the ski helmet, by 6 different spatially distributed sound stimuli per each condition. Each of the subjects had to react when hearing the sound as soon as possible and to signalize the correct side of the sound arrival. Results: The results showed a significant difference in the ability to localize the specific ski sounds; 72.5±15.6% of correct answers without a helmet vs. 61.3±16.2% with a helmet (p < 0.01. However, the performance on this test did not depend on whether they were used to wearing a helmet (p = 0.89. In identifying the timing, at which the sound was firstly perceived, the results were also in favor of the subjects not wearing a helmet. The subjects reported hearing the ski sound clues at 73.4±5.56 m without a helmet vs. 60.29±6.34 m with a helmet (p < 0.001. In that case the results did depend on previously used helmets (p < 0.05, meaning that that regular usage of helmets might help to diminish the attenuation of the sound identification that occurs because of the helmets. Conclusions: Ski helmets might limit the ability of a skier to localize the direction of the sounds of danger and might interfere with the moment, in which the sound is firstly heard.

Chalela, Julio A

2018-04-01

Headaches among military personnel are very common and headgear wear is a frequently identified culprit. Helmet wear may cause migrainous headaches, external compression headache, other primary cranial neuralgias, and occipital neuralgia. The clinical features and the response to treatment allow distinction between the different types of headaches. Headaches among aviators are particularly concerning as they may act as distractors while flying and the treatment options are often incompatible with flying status. A 24-yr-old door gunner presented with suboccipital pain associated with the wear of his helmet. He described the pain as a paroxysmal stabbing sensation coming in waves. The physical exam and history supported the diagnosis of primary occipital neuralgia. Systemic pharmacological options were discussed with the soldier, but rejected due to his need to remain in flying status. An occipital nerve block was performed with good clinical results, supporting the diagnosis of occipital neuralgia and allowing him to continue as mission qualified. Occipital neuralgia can be induced by helmet wear in military personnel. Occipital nerve block can be performed in the deployed setting, allowing the service member to remain mission capable and sparing him/her from systemic side effects.Chalela JA. Helmet-induced occipital neuralgia in a military aviator. Aerosp Med Hum Perform. 2018; 89(4):409-410.

Predicament of Chinese legislation on genetically modified food (GMF) labeling management and solutions - from the perspective of the new food safety law.

Li, Wei; Li, Han

2017-11-01

This paper considers the background of Article 69 of the newly revised Food Safety Law in China in combination with the current situation of Chinese legislation on GMF labeling management, compared with a foreign genetically modified food labeling management system, revealing deficiencies in the Chinese legislation with respect to GMF labeling management, and noting that institutions should properly consider the GMF labeling management system in China. China adheres to the principle of mandatory labeling based on both product and processes in relation to GMFs and implements a system of process-centered mandatory labeling under a negotiation-construction form. However, China has not finally defined the supervision mode of mandatory labeling of GMFs through laws, and this remains a challenge for GMF labeling management when two mandatory labeling modes coexist. Since April 2015 and October 1, 2015 when the Food Safety Law was revised and formally implemented respectively, the applicable judicial interpretations and enforcement regulations have not made applicable revisions and only principle-based terms have been included in the Food Safety Law, it is still theoretically and practically difficult for mandatory labeling of GMFs in juridical practices and conflicts between the principle of GMF labeling and the purpose that safeguards consumers' right to know remain. The GMF labeling system should be legislatively and practically improved to an extent that protects consumers' right to know. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

Biomechanical headforms are used for helmet certification testing and reconstructing helmeted head impacts; however, their biofidelity and direct applicability to human head and helmet responses remain unclear. Dynamic responses of cadaver heads and three headforms and residual foam liner deformations were compared during motorcycle helmet impacts. Instrumented, helmeted heads/headforms were dropped onto the forehead region against an instrumented flat anvil at 75, 150, and 195 J. Helmets were CT scanned to quantify maximum liner crush depth and crush volume. General linear models were used to quantify the effect of head type and impact energy on linear acceleration, head injury criterion (HIC), force, maximum liner crush depth, and liner crush volume and regression models were used to quantify the relationship between acceleration and both maximum crush depth and crush volume. The cadaver heads generated larger peak accelerations than all three headforms, larger HICs than the International Organization for Standardization (ISO), larger forces than the Hybrid III and ISO, larger maximum crush depth than the ISO, and larger crush volumes than the DOT. These significant differences between the cadaver heads and headforms need to be accounted for when attempting to estimate an impact exposure using a helmet's residual crush depth or volume.

Head injuries are the main cause of death in bicycle-related accidents among children and adolescents. According to a Cochrane Review, the risk of head injury (OR 0.31; 95% CI 0.26-0.37) or brain injury (OR 0.31; 95% CI 0.23-0.42) decreases by 69% if a helmet is worn. This study presents the prevalence of helmet use in cycling children and adolescents in Germany and the proportion of head injuries that could be prevented by wearing helmets. The potential effects of increased helmet wearing rates on the population attributable risk percentage for head injuries (PAR%) are demonstrated. The prevalence of helmet use in children aged 3-17 years was analysed using data from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS). The percentage of head injuries preventable by helmet use in this group is estimated by calculating PAR%. Prevalence rates of helmet use and odds ratios from a Cochrane Review about the effectiveness of bicycle helmets for the prevention of head injuries were used for analysis. The potential effect of increased helmet use is shown in 3 scenarios by means of differences of PAR% values in the most relevant age groups. The older the children, the less likely they are to wear a helmet: 89.5% (95% CI 88.0%-90.8%) of the 3- to 6-year-old children wear a helmet when cycling but only 11.0% (95% CI 9.3%-12.9%) of 14- to 17-year-old adolescents do. In the youngest group (3-6 years) 19% of bicycle-related head injuries are attributable to the non-use of helmets, but this proportion rises to 67% in the oldest group (14-17 years). The PAR% of head injuries associated with not wearing a helmet may be reduced by more than a third by increasing the helmet wearing rate to 67% (2 out of 3) among adolescents, and may be reduced to half if 75% of adolescents wore a helmet. Particularly older children and adolescents hardly use bicycle helmets, hence the rate of preventable head injury is high. Efforts towards increasing helmet use

Full Text Available Introduction: Work-related traumatic brain injury (TBI caused by falls is a catastrophic event that leads to disabilities and high socio-medical costs. This study aimed to measure the magnitude of the preventive effect of safety helmets on clinical outcomes and to compare the effect across different heights of fall. Methods: We collected a nationwide, prospective database of work-related injury patients who visited the 10 emergency departments between July 2010 and October 2012. All of the adult patients who experienced work-related fall injuries were eligible, excluding cases with unknown safety helmet use and height of fall. Primary and secondary endpoints were intracranial injury and in-hospital mortality. We calculated adjusted odds ratios (AORs of safety helmet use and height of fall for study outcomes, and adjusted for any potential confounders. Results: A total of 1298 patients who suffered from work-related fall injuries were enrolled. The industrial or construction area was the most common place of fall injury occurrence, and 45.0% were wearing safety helmets at the time of fall injuries. The safety helmet group was less likely to have intracranial injury comparing with the no safety helmet group (the adjusted odds ratios (ORs (95% confidence interval (CI: 0.42 (0.24–0.73, however, there was no statistical difference of in-hospital mortality between two groups (the adjusted ORs (95% CI: 0.83 (0.34–2.03. In the interaction analysis, preventive effects of safety helmet on intracranial injury were significant within 4 m height of fall. Conclusions: A safety helmet is associated with prevention of intracranial injury resulting from work-related fall and the effect is preserved within 4 m height of fall. Therefore, wearing a safety helmet can be an intervention for protecting fall-related intracranial injury in the workplace.

A Thermal Test System for Helmet Cooling Studies

Full Text Available One of the primary causes of discomfort to both irregular and elite cyclists is heat entrapment by a helmet resulting in overheating and excessive sweating of the head. To accurately assess the cooling effectiveness of bicycle helmets, a heated plastic thermal headform has been developed. The construction consists of a 3D-printed headform of low thermal conductivity with an internal layer of high thermal mass that is heated to a constant uniform temperature by an electrical heating element. Testing is conducted in a wind tunnel where the heater power remains constant and the resulting surface temperature distribution is directly measured by 36 K-type thermocouples embedded within the surface of the head in conjunction with a thermal imaging camera. Using this new test system, four bicycle helmets were studied in order to measure their cooling abilities and to identify ‘hot spots’ where cooling performance is poor.

Bicycle-related head injuries are an important cause of death and disability, despite the availability of helmets. The objective of this study was to evaluate the effectiveness of a school-based bicycle helmet promotion program in increasing helmet use by children while controlling for secular trends. Two high-income and two low-income schools in an urban Canadian community were selected to receive a bicycle helmet promotion intervention, with the remaining 18 schools serving as controls. Approximately 1800 observations of bicycling children were made at randomly selected observational sites 2 to 5 months after the intervention to assess changes in behavior. Helmet use at all observation sites tripled from 3.4% (1990, preintervention) to 16% (1991, postintervention). In the high-income intervention area, observed helmet use rose dramatically from 4% to 36% in contrast to the more modest increase in the high-income control area from 4% to 15%. In the low-income intervention area, there was a modest increase from 1% to 7%, but it did not differ from the increase in the low-income control area from 3% to 13%. The program was highly successful in children of high-income families but not in children of low-income families. Developing strategies for low-income families remains a priority.

With the recent worldwide increase in ski helmet use, new market trends are developing, including audio helmets for listening to music while skiing or snowboarding. The aim of this study was to evaluate whether listening to music with an audio ski helmet impairs reaction time to peripheral stimuli. A within-subjects design study using the Compensatory-Tracking-Test was performed on 65 subjects (36 males and 29 females) who had a mean age of 23.3 ± 3.9 years. Using repeated measures analysis of variance, we found significant differences in reaction times between the 4 test conditions (p=0.039). The lowest mean reaction time (± SE) was measured for helmet use while listening to music (507.9 ± 13.2 ms), which was not different from helmet use alone (514.6 ± 12.5 ms) (p=0.528). However, compared to helmet use while listening to music, reaction time was significantly longer for helmet and ski goggles used together (535.8 ± 14.2 ms, p=0.005), with a similar trend for helmet and ski goggles used together while listening to music (526.9 ± 13.8 ms) (p=0.094). In conclusion, listening to music with an audio ski helmet did not increase mean reaction time to peripheral stimuli in a laboratory setting. © Georg Thieme Verlag KG Stuttgart · New York.

In cases of possible cervical spine injury, medical professionals must be prepared to achieve rapid airway access while concurrently restricting cervical spine motion. Face mask removal (FMR), rather than helmet removal (HR), is recommended to achieve this. However, no studies have been reported that compare FMR directly with HR. The purpose of this study was to compare motion, time, and perceived difficulty in two commonly used American football helmets between FMR and HR techniques, and when helmet air bladders were deflated before HR compared with inflated scenarios. The study incorporated a repeated measures design and was performed in a controlled laboratory setting. Participants included 22 certified athletic trainers (15 men and seven women; mean age, 33.9±10.5 years; mean experience, 11.4±10.0 years; mean height, 172±9.4 cm; mean mass, 76.7±14.9 kg). All participants were free from upper extremity or central nervous system pathology for 6 months and provided informed consent. Dependent variables included head excursion in degrees (computed by subtracting the minimum position from the maximum position) in each of the three planes (sagittal, frontal, transverse), time to complete the required task, and ratings of perceived exertion. To address our study purposes, we used two-by-two repeated-measures analysis of variance (removal technique×helmet type, helmet type×deflation status) for each dependent variable. Independent variables consisted of removal technique (FMR and HR), helmet type (Riddell Revolution IQ [RIQ] and VSR4), and helmet deflation status (deflated [D], inflated, [I]). After familiarization, participants conducted two successful trials for each of six conditions in random order (RIQ-FMR, VSR4-FMR, RIQ-HR-D, VSR4-HR-D, RIQ-HR-I, and VSR4-HR-I). Face masks, helmets, and shoulder pads were removed from a live model wearing a properly fitted helmet and shoulder pads. The participant and an investigator stabilized the model's head. A six

in adults, noninvasive ventilation via a helmet is associated with significantly greater noise than nasal and facial masks. We hypothesized that noise exposure could be increased with neonatal helmet continuous positive airway pressure (CPAP) in comparison with conventional nasal CPAP (nCPAP). Our primary objective was to compare the noise intensity produced by a neonatal helmet CPAP and a conventional nCPAP system. Furthermore, we aimed to evaluate the effect of the gas flow rate and the presence of the humidifier and the filter on noise levels during neonatal helmet CPAP treatment. in this bench study, noise intensity was measured in the following settings: helmet CPAP, nCPAP, incubator and the neonatal intensive care unit. In helmet CPAP, noise measurements were performed at different gas flow rates (8, 10 and 12 l/min), while in nCPAP, the flow rate was 8 l/min. For both CPAP systems, the level of pressure was maintained constant at 5 cmH(2) O. during neonatal helmet CPAP, the median (interquartile range) noise levels were significantly higher than those during nCPAP: 70.0 dB (69.9-70.4) vs. 62.7 dB (62.5-63.0); PCPAP, the noise intensities changed with increasing flow rate and with the presence of a humidifier or a filter. noise intensities generated by the neonatal helmet CPAP were significantly higher than those registered while using a conventional nCPAP system. In the helmet, the noise intensity depends on the gas flow rate, and the presence of a humidifier and a filter in the system. 2010 The Acta Anaesthesiologica Scandinavica Foundation.

Current MEG instruments derive the whole-head coverage by utilizing a helmet-shaped opening at the bottom of the dewar. These helmets, however, are quite a bit larger than most people's heads so subjects commonly lean against the back wall of the helmet in order to maintain a steady position. In such cases the anterior brain sources may be too distant to be picked up by the sensors reliably. Potential "invisibility" of the frontal and anterior temporal sources may be particularly troublesome for the studies of cognition and language, as they are subserved significantly by these areas. We examined the sensitivity of the distributed anatomically-constrained MEG (aMEG) approach to the head position ("front" vs. "back") secured within a helmet with custom-tailored bite-bars during a lexical decision task. The anterior head position indeed resulted in much greater sensitivity to language-related activity in frontal and anterior temporal locations. These results emphasize the need to adjust the head position in the helmet in order to maximize the "visibility" of the sources in the anterior brain regions in cognitive and language tasks.

To examine changes in child car restraint practices in low socioeconomic areas following the introduction of mandatory child car restraint legislation in New South Wales (NSW), Australia. Data from two cross-sectional studies of child car restraint use at pre-schools, early childhood centres and primary schools before and after the introduction of legislating mandatory age-appropriate car restraint use for children up to the age of seven years was used in this analysis. All included observations were from local government areas with socioeconomic status in the lowest 30% of urban Sydney. Children aged 2-5 years were observed in their vehicles as they arrived at observation sites (107 pre-legislation, 360 post-legislation). Multilevel logistic regression was used to examine changes in observed age-appropriate and correct use of car restraints. Age-appropriate car restraint use was higher post-legislation than pre-legislation. After controlling for child's age, parental income, language spoken at home and adjusting for clustering, the odds of children being appropriately restrained post-legislation were 2.3 times higher than in the pre-legislation sample, and the odds of them being correctly restrained were 1.6 times greater. Results indicate an improvement in car restraint practices among children aged 2-5 in low socioeconomic areas after introduction of child restraint laws. Implications : Despite improvements observed with enhanced legislation, further efforts are required to increase optimal child car restraint use. © 2013 The Authors.

Non-invasive mechanical ventilation (NIV) has proved to be an excellent technique in selected critically ill patients with different forms of acute respiratory failure. However, NIV can fail on account of the severity of the disease and technical problems, particularly at the interface. The helmet could be an alternative interface compared to face mask to improve NIV success. We performed a clinical review to investigate the main physiological and clinical studies assessing the efficacy and related issues of NIV delivered with a helmet. A computerized search strategy of MEDLINE/PubMed (January 2000 to May 2012) and EMBASE (January 2000 to May 2012) was conducted limiting the search to retrospective, prospective, nonrandomized and randomized trials. We analyzed 152 studies from which 33 were selected, 12 physiological and 21 clinical (879 patients). The physiological studies showed that NIV with helmet could predispose to CO₂ rebreathing and increase the patients' ventilator asynchrony. The main indications for NIV were acute cardiogenic pulmonary edema, hypoxemic acute respiratory failure (community-acquired pneumonia, postoperative and immunocompromised patients) and hypercapnic acute respiratory failure. In 9 of the 21 studies the helmet was compared to a face mask during either continous positive airway pressure or pressure support ventilation. In eight studies oxygenation was similar in the two groups, while the intubation rate was similar in four and lower in three studies for the helmet group compared to face mask group. The outcome was similar in six studies. The tolerance was better with the helmet in six of the studies. Although these data are limited, NIV delivered by helmet could be a safe alternative to the face mask in patients with acute respiratory failure.

In some areas, it is a commonly accepted emergency medical technician protocol to remove a helmet during the initial management of suspected cervical spine injures. After a comprehensive survey of relevant literature, four primary reasons why Emergency Medical Services professionals would desire to remove a helmet emerge. Sources suggest that the presence of a helmet might: 1) interfere with immobilization of the athlete; 2) interfere with the ability to visualize injuries; 3) cause hyperflexion of the cervical spine; and 4) prevent proper airway management during a cardiorespiratory emergency. Many available protocols are designed for the removal of closed chamber motorcycle helmets that do not have removable face masks. There are a great number of differing viewpoints regarding this issue. The varying viewpoints are results of the failure of many emergency medical technician management protocols to address the unique situation presented by a football helmet. We: 1) demonstrate that football helmet removal is potentially dangerous and unnecessary, 2) suggest that cardiorespiratory emergencies can be effectively managed without removing the helmet, and 3) provide sports medicine professional with information that may be used to establish a joint Emergency Medical Services/Sports Medicine emergency action plan.

EUROCOPTER has been under contract to the French and German ministries of defence for five years to develop the TIGER, a second generation anti-tank helicopter. A piloting thermal imager has been installed on a steerable platform in the helicopter nose in order to achieve the possibility of flying round the clock. In addition to this sensor, which is sensitive at a wavelength of 10 micrometers , the German side has proposed using an Integrated Helmet System in the PAH 2. This helmet, manufactured by GEC-Marconi Avionics, incorporates two cathode ray tubes (CRT) and two image intensifier tubes which allow the pilot to use an additional sensor in the visible and near infrared spectrum. The electronic part will be built by Teldix. EUROCOPTER DEUTSCHLAND has received the first demonstrator of this helmet for testing in the EUROCOPTER Visionics Laboratory. Later, the C-prototype will be integrated into a BK 117 helicopter (AVT Avionik Versuchstrager). This new helmet has a field of view of 40 degree(s), and exit pupil of 15 mm and improved possibilities of adjusting the optical part. Laboratory tests have been carried out to test important parameters like optical resolution under low light level conditions, field of view, eye relief or exit pupil. The CRT channels have been tested for resolution, distortion, vignetting and homogeneity. The requirements and the properties of the helmet, test procedures and the results of these tests are presented in the paper.

Almost half of the global traffic crashes involve vulnerable groups such as pedestrian, cyclists and two-wheeler users. The main objective of this study was to determine the factors that influence standard of the safety helmets used amongst food delivery workers by presence of Standard and Industrial Research Institute of Malaysia (SIRIM) certification label. A cross sectional study was conducted amongst 150 food delivery workers from fast food outlets in the vicinity of Selangor and Kuala Lumpur. During observation, safety helmets were classified as standard safety helmet in the presence of SIRIM label and non-standard in the absence of the label. They were approached for questionnaire participation once consent was obtained and were requested to exchange their safety helmet voluntarily with a new one after the interview. Data analysis was carried out using SPSS. Chi square and logistic regression analysis was applied to determine the significance and odds ratio of the variables studied, respectively (penetration test, age, education level, knowledge, crash history, types of safety helmet, marital status and years of riding experience) against the presence of SIRIM label. The response rate for this study was 85.2%. The prevalence of non-standard helmets use amongst fast food delivery workers was 55.3%. Safety helmets that failed the penetration test had higher odds of being non-standard helmets compared with safety helmets passing the test. Types of safety helmet indicated half-shell safety helmets had higher odds to be non-standard safety helmets compared to full-shell safety helmets. Riders with more years of riding experience were in high odds of wearing non-standard safety helmets compared to riders with less riding experience. Non-standard (non-SIRIM approved) helmets were more likely to be half-shell helmets, were more likely to fail the standards penetration test, and were more likely to be worn by older, more experienced riders. The implications of these

Full Text Available This paper presents the development process of a bicycle helmet through individual research, creation, presentation and analysis of the results of the most important product development stages. The quality of the development and manufacturing process of the protective equipment for extreme sports is an imperative for a successful product and its flawless function. The design of the bicycle helmet is made following the rules of the design in order to create a well-founded and functional product. After creating design sketches, a virtual prototype was developed in "SolidWorks" using the required ergonomic dimensions. 3D printed model of the human head with adapted ergonomic dimensions and the designed bicycle helmet was developed in order to verify the applied ergonomic measures. The virtual model will be used as an input in the finite element analysis of the helmet impact test based on the EN1078 standard and the aerodynamic simulations executed in "SolidWorks Simulation and Flow Simulation", for verification of the impact and aerodynamic properties. Virtual testing of aerodynamic features and the ability of the bicycle helmet to allow ventilation of the user's head indicate that the helmet performs its function in the desired way. Also, the virtual prototype will be used for the production process simulation in "SolidWorks Plastics" in order to analyze the production of the bicycle helmet. The polycarbonate helmet outer shell is subject to a number of simulations for the sake of analyzing the production process in order to obtain the desired characteristics of the polycarbonate outer shell and to avoid the disadvantages that occur in the manufacturing process. The main goal of this paper is to develop a safety bicycle helmet with improved ergonomic, validation of impact, aerodynamic characteristics and production process in order to produce a high quality product for mass use.

Full Text Available Background: The incidence of fatal accidents are more in two wheeler drivers compared to four wheeler drivers. Head injury is of serious concern when recovery and prognosis of the patients are warranted, helmets are being used for safety purposes by moped, scooters and motorcycle drivers. Although, helmets are designed with cushioning effect to prevent head injuries but there are evidences of increase risk of neck injuries and reduced peripheral vision and hearing in helmet users. A complete full coverage helmets provide about less than 3 percent restrictions in horizontal peripheral visual field compared to rider without helmet. The standard company patented ergonomically designed helmets which does not affect the peripheral vision neither auditory reaction time. Objective: This pilot study aimed to evaluate the peripheral field of vision and auditory and visual reaction time in a hypertensive, diabetic and healthy male and female in order to have a better insight of protective characteristics of helmet in health and disease. Method: This pilot study carried out on age matched male of one healthy, one hypertensive and one diabetic and female subject of one healthy, one hypertensive and one diabetics. The field of vision was assessed by Lister’s perimeter whereas auditory and visual reaction time was recorded with response analyser. Result : Gender difference was not noted in peripheral field of vision but mild difference was found in auditory reaction time for high frequency and visual reaction time for both red and green colour in healthy control. But lateral and downward peripheral visual field was found reduced whereas auditory and visual reaction time was found increased in both hypertensive and diabetic subject in both sexes. Conclusion: Peripheral vision, auditory reaction time and visual reaction time in hypertensive and diabetics may lead to vulnerable accident. Helmet use has proven to reduce extent of injury in motorcyclist and

How ought public officials address policy choices that entail trade-offs between desirable public health goods? Increasing cycling improves public health both by promoting physical activity and by decreasing vehicle use, thus reducing vehicular emissions. Proponents of bicycle helmets argue that, used properly, they protect individual cyclists; however, there is concern that mandating helmet use may result in a decrease in cycling. In 2012, New York City Mayor Michael Bloomberg opposed a bicycle helmet mandate, concerned that it would have a negative impact on the city's cycling rate, which he had sought to increase. The mayor did not explain his rationale, leaving constituents unsure why he opposed the proposal. This case study underscores the challenge of creating public policy in the context of competing public health goods.

To determine if health outcomes and demographics differ according to helmet status between persons with cycling-related traumatic brain injuries (TBI). This is a retrospective study of 128 patients admitted to the Montreal General Hospital following a TBI that occurred while cycling from 2007-2011. Information was collected from the Quebec trauma registry and the coroner's office in cases of death from cycling accidents. The independent variables collected were socio-demographic, helmet status, clinical and neurological patient information. The dependent variables evaluated were length of stay (LOS), extended Glasgow outcome scale (GOS-E), injury severity scale (ISS), discharge destination and death. 25% of cyclists wore a helmet. The helmet group was older, more likely to be university educated, married and retired. Unemployment, longer intensive care unit (ICU) stay, severe intracranial bleeding and neurosurgical interventions were more common in the no helmet group. There was no significant association between the severity of the TBI, ISS scores, GOS-E or death and helmet wearing. The median age of the subjects who died was higher than those who survived. Cyclists without helmets were younger, less educated, single and unemployed. They had more severe TBIs on imaging, longer LOS in ICU and more neurosurgical interventions. Elderly cyclists admitted to the hospital appear to be at higher risk of dying in the event of a TBI.

Under national laws, some of these limitations appear as mandatory rules based on public policy. These kind of rules shall apply despite the foreign law that could be apply through the conflict of laws rule, or choice of law made by the parties. In other words, in matters of private international law internal mandatory rules replace the rules of the law of a foreign state. However, the problem is that the Law of Ukraine «On Private International Law» does not set criteria for inclusion of certain provisions of the substantive law to the appropriate category. Therefore, in practice to attribute some provisions of substantive law to the mandatory rules is a problematic issue. Especially it concerns the rules of competition law, which in most cases characterize as public law rules. The article is devoted to the coverage of problematic issues of application mandatory rules of Ukrainian competition legislation in cases with a foreign element. Analyzed the approaches of different scholars on the concept of mandatory rules. Paid attention on the differences of application mandatory and imperative rules of competition law of Ukraine.

Motorcycles make up 81 % of the total vehicle population and 74 % of road traffic deaths in Lao PDR. Helmets reduce the risk and severity of injuries resulting from motorcycle accidents by 72 %. Although Lao law mandates motorcycle helmet use among drivers and passengers, the prevalence of helmet use in Luang Prabang, Lao PDR is unknown. This project aimed to measure the prevalence of motorcycle helmet use among riders (i.e., drivers and passengers) in Luang Prabang. An observational survey in Luang Prabang was conducted in February 2015 to measure the prevalence of motorcycle helmet use among drivers and passengers. Additionally, non-helmet wearing riders were surveyed to identify the reasons for helmet non-use. Of 1632 motorcycle riders observed, only 16.2 % wore helmets. Approximately 29 % of adults wore helmets while less than 1 % of all children wore helmets. When surveyed about attitudes towards helmet use, the majority of adult drivers indicated that they did not like how adult helmets feel or made them look. Additionally, almost half of motorcyclists who did not own child helmets reported that their child was too young to wear a helmet. Our finding that children wear helmets at significantly lower rates compared to adults is consistent with findings from neighboring countries in Southeast Asia. Results of this study have implications for public health campaigns targeting helmet use, especially among children.

The proportion of head injuries among ice-skaters in this study was greater than that observed for participants in other types of skating, for which helmet use is recommended and often required. Children should wear a helmet during recreational ice-skating. Mandatory helmet use by pediatric ice-skaters at indoor rinks should be implemented. Use of other types of protective equipment, such as wrist guards, knee pads, and elbow pads, should be considered for prevention of injuries to the extremities during ice-skating. Caution should be used when allowing young children to participate in recreational ice-skating. Additional research should be conducted in other populations, to corroborate these findings and to evaluate ice-skating safety recommendations for children.

Up to 75% of skateboarders and snowboarders admitted to the hospital sustain head injuries. It is unclear why not all children and teenagers wear helmets while snowboarding and skateboarding given the protection they afford. To report on the prevalence of, and factors associated with, skateboarding and snowboarding in injured children and to explore factors that influence helmet use, head injury, and hospitalization in this sample. A cross-sectional study of skateboard- and snowboard-associated injuries from 2003 to 2012 among individuals younger than age 18 years using National Electronic Injury Surveillance System (NEISS) data from approximately 100 hospitals. Helmet use, head injury, and hospitalization. Of 1742 patients in the study, 852 (48.9%) and 890 (51.1%) were skateboarders and snowboarders, respectively. Overall, 907 (52.1%) did not use helmets, and 704 (40.4%) sustained head injuries. Multiple logistic regression analysis showed that age, race/ethnicity, location of boarding, and engaging in skateboarding influenced helmet use. Sex, race/ethnicity, helmet use, and skateboarding predicted head injury. Age, sex, skateboarding, and head injury predicted hospital admission. Statistically significant differences exist in helmet use, head injury, and hospitalization rates between skateboarders and snowboarders. Our findings suggest that injury prevention and outreach programs are needed to increase helmet use and reduce the risk of head injury and hospitalization in skateboarders and other at-risk groups. Further studies are needed to clarify the association between race/ethnicity and helmet use among skateboarders and snowboarders.

Descriptive laboratory study. To determine whether the placement of padding beneath the occiput after helmet removal is an effective intervention to maintain neutral sagittal cervical spine alignment in a position comparable with the helmeted condition. Current on-field recommendations for managing football athletes with suspected cervical spine injuries call for face mask removal, rather than helmet removal, because the combination of helmet and shoulder pads has been shown to maintain neutral cervical alignment. Therefore, in cases when helmet removal is required, recommendations also call for shoulder pad removal. Because removal of equipment causes motion, any technique that postpones the need to remove the shoulder pads would reduce prehospital motion. Four lateral radiographs of 20 male participants were obtained (age = 23.6 ± 2.7 years). Radiographs of participants wearing shoulder pads and helmet were first obtained. The helmet was removed and radiographs of participants with occipital padding were obtained immediately and 20 minutes later and finally without occipital padding. Cobb angle measurements for C2-C6 vertebral segments were determined by an orthopedic spine surgeon blinded to the study's purpose. Intraobserver reliability was determined using intraclass coefficient analysis. Measurements were analyzed using a 1×4 repeated-measures analysis of variance and post hoc pairwise comparisons with Bonferroni correction. Intraobserver analysis showed excellent reliability (intraclass correlation = 1.0; 95% confidence interval [CI], 0.999-1.0). Repeated-measures analysis of variance detected significant differences (F(3,17) = 13.34; P football helmet in the field, occipital padding (along with full body/head immobilization techniques) may be used to limit cervical lordosis, allowing safe delay of shoulder pad removal.

Experimental investigations on the cooling of a motorcycle helmet with phase change material (PCM

Full Text Available The thermal comfort of motorcycle helmet during hot weather is important as it can affect the physiological and psychological condition of the rider. This paper examines the use of phase change material (PCM to cool a motorcycle helmet and presents the experimental investigations on the influences of the simulated solar radiation, wind speed, and heat generation rate on the cooling system. The result shows that the PCM-cooled helmet is able to prolong the thermal comfort period compared to a normal helmet. The findings also indicate that the heat generation from the head is the predominant factor that will affect the PCM melting time. Simulated solar radiation and ram-air due to vehicle motion under adiabatic condition can have very little influences on the PCM melting time. The results suggested that the helmet usage time would be influenced by the amount of heat generated from the head. Some major design considerations based on these findings have been included. Although this investigation focuses on the cooling of a motorcyclist helmet, the findings would also be useful for the development of PCM-cooling systems in other applications.

Governing GMOs: The (Counter Movement for Mandatory and Voluntary Non-GMO Labels

Directory of Open Access Journals (Sweden)

Carmen Bain

2014-12-01

Full Text Available Since 2012 the anti-GMO (genetically modified organism movement has gained significant grassroots momentum in its efforts to require mandatory GMO food labels through state-level ballot and legislative efforts. Major food and agriculture corporations are opposed to mandatory GMO labels and have successfully defeated most of these initiatives. Nevertheless, these battles have garnered significant media attention and re-energized the debate over GMO crops and foods. In this paper, we argue that one of the most significant outcomes of this fight is efforts by food retailers and value-based food companies to implement voluntary non-GMO labels and brands. We draw on the governance and political consumerism literature to explore (counter movement efforts for mandatory labels and how these efforts are being institutionalized through private voluntary governance institutions. Our assessment is based on in-depth, semi-structured interviews with key informants from consumer and environmental organizations, agriculture and biotech companies, and government regulatory agencies, as well as a content analysis of food industry websites. A growing number of food retailers recognize the reputational and economic value that new niche markets for non-GMO foods can offer, while the anti-GMO movement views these efforts as a step in the direction of mandatory GMO labels. We conclude that voluntary labels may act to settle the labeling debate by mollifying agri-food industry concerns about mandatory labeling and meeting the desire of political consumers for greater choice and transparency but without addressing the broader social and environmental sustainability concerns that drives the anti-GMO movement in the first place.

This study was carried out to investigate reasoning and interpretation of motorcyclists for not using helmet utilizing qualitative methodology of 'grounded theory'. The field of the study was Kerman, a cultural-historical city at the south-east of Iran. Participants were 21 young male motorcyclists. Two sampling strategies were used: maximum variation and snowball sampling. To collect data, in-depth, open-ended interviews were conducted. Data analysis yielded seven categories: fatalism; a barrier to social relationships; peer group pressure and negative labelling; messing up the appearance; disturbance in hearing and vision; barrier to normal breathing; and heaviness and superfluity of helmet. Based on the findings of the current study, it could be concluded that socio-cultural contexts, motorcyclists' worldview and partly helmet-related problems are of the main factors which affect motorcycling. Therefore, the studies, policy-makings, and intervening programmes to control injury and to promote safety among motorcyclists should be focused on socio-cultural barriers to helmet use in general and changing the motorcyclists' standpoints toward fatalism in particular. Helmet-related problems should be considered, too.

The aerodynamic drag of three different time-trial cycling helmets was analyzed numerically for two different cyclist head positions. Computational Fluid Dynamics (CFD) methods were used to investigate the detailed airflow patterns around the cyclist for a constant velocity of 15 m/s without wind. The CFD simulations have focused on the aerodynamic drag effects in terms of wall shear stress maps and pressure coefficient distributions on the cyclist/helmet system. For a given head position, the helmet shape, by itself, obtained a weak effect on a cyclist's aerodynamic performance (CFD results have also shown that both helmet shape and head position significantly influence drag forces, pressure and wall shear stress distributions on the whole cyclist's body due to the change in the near-wake behavior and in location of corresponding separation and attachment areas around the cyclist.

This article proposes a method for a comprehensive assessment of the effect of integral motorcycle helmets on physiological and cognitive responses of motorcyclists. To verify the reliability of commonly used tests, we conducted experiments with 5 motorcyclists. We recorded changes in physiological parameters (heart rate, local skin temperature, core temperature, air temperature, relative humidity in the space between the helmet and the surface of the head, and the concentration of O(2) and CO(2) under the helmet) and in psychological parameters (motorcyclists' reflexes, fatigue, perceptiveness and mood). We also studied changes in the motorcyclists' subjective sensation of thermal comfort. The results made it possible to identify reliable parameters for assessing the effect of integral helmets on performance, i.e., physiological factors (head skin temperature, internal temperature and concentration of O(2) and CO(2) under the helmet) and on psychomotor factors (reaction time, attention and vigilance, work performance, concentration and a subjective feeling of mood and fatigue).

Proper helmet fit is important for optimizing head protection during an impact, yet many motorcyclists wear helmets that do not properly fit their heads. The goals of this study are i) to quantify how a mismatch in headform size and motorcycle helmet size affects headform peak acceleration and head injury criteria (HIC), and ii) to determine if peak acceleration, HIC, and impact speed can be estimated from the foam liner's maximum residual crush depth or residual crush volume. Shorty-style helmets (4 sizes of a single model) were tested on instrumented headforms (4 sizes) during linear impacts between 2.0 and 10.5m/s to the forehead region. Helmets were CT scanned to quantify residual crush depth and volume. Separate linear regression models were used to quantify how the response variables (peak acceleration (g), HIC, and impact speed (m/s)) were related to the predictor variables (maximum crush depth (mm), crush volume (cm 3 ), and the difference in circumference between the helmet and headform (cm)). Overall, we found that increasingly oversized helmets reduced peak headform acceleration and HIC for a given impact speed for maximum residual crush depths less than 7.9mm and residual crush volume less than 40cm 3 . Below these levels of residual crush, we found that peak headform acceleration, HIC, and impact speed can be estimated from a helmet's residual crush. Above these crush thresholds, large variations in headform kinematics are present, possibly related to densification of the foam liner during the impact. Copyright © 2017 Elsevier Ltd.

The effects of dynamic friction in oblique motorcycle helmet impacts

Science.gov (United States)

Bonugli, Enrique

The purpose of this study was to determine the frictional properties between the exterior surface of a motorcycle helmet and 'typical' roadway surfaces. These values were compared to abrasive papers currently recommended by government helmet safety standards and widely used by researchers in the field of oblique motorcycle helmet impacts. A guided freefall test fixture was utilized to obtain nominal impact velocities of 5, 7 and 9 m/s. The impacting surfaces were mounted to an angled anvil to simulate off-centered oblique collision. Head accelerations and impact forces were measured for each test. Analysis of the normal and tangential forces imparted to the contact surface indicated that the frictional properties of abrasive papers differ from asphalt and cement in magnitude, duration and onset. Reduction in head acceleration, both linear and angular, were observed when asphalt and cement were used as the impacting surface. Roofing shingle was determined to be a more suitable material to simulate 'typical' roadway surfaces however, this may not be ideal for use in a controlled laboratory setting. In a laboratory setting, the author recommends cement as a best-fit material to simulate roadway surface for use in oblique motorcycle helmet impacts since this material displayed characteristics that closely resemble asphalt and is currently used as a roadway construction material.

The recommendation issued by the American Academy of Pediatrics in the early 1990s to position infants on their back during sleep to prevent sudden infant death syndrome (SIDS) has dramatically reduced the number of deaths due to SIDS but has also markedly increased the prevalence of positional skull deformation in infants. Deformation of the base of the skull occurs predominantly in very severe deformational plagiocephaly and is accompanied by facial asymmetry, as well as an altered ear position, called ear shift. Moulded helmet therapy has become an accepted treatment strategy for infants with deformational plagiocephaly. The aim of this study was to determine whether facial asymmetry could be corrected by moulded helmet therapy. In this retrospective, single-centre study, we analysed facial asymmetry of 71 infants with severe deformational plagiocephaly with or without deformational brachycephaly who were undergoing moulded helmet therapy between 2009 and 2013. Computer-assisted, three-dimensional, soft-tissue photographic scanning was used to record the head shape before and after moulded helmet therapy. The distance between two landmarks in the midline of the face (i.e., root of the nose and nasal septum) and the right and left tragus were measured on computer-generated indirect and objective 3D photogrammetry images. A quotient was calculated between the two right- and left-sided distances to the midline. Quotients were compared before and after moulded helmet therapy. Infants without any therapy served as a control group. The median age of the infants before onset of moulded helmet therapy was 5 months (range 3-16 months). The median duration of moulded helmet therapy was 5 months (range 1-16 months). Comparison of the pre- and post-treatment quotients of the left vs. right distances measured between the tragus and root of the nose (n = 71) and nasal septum (n = 71) revealed a significant reduction of the asymmetry (Tragus-Nasion-Line Quotient: 0

2016-07-01

Full Text Available BACKGROUND Motor vehicle crashes are a major cause of fatality all over the world. By 2020, motor vehicle injury is projected to become the third leading contributor to the global burden of disease in the world. Motor cyclists are about 25 times more likely than car occupants to die in Road Traffic Accidents. Data on the incidence and types of crashes is required to guide safety policy. Knowledge of how injuries are caused and of what type they are of valuable instrument for identifying interventions and monitoring the effectiveness of intervention. The present study was done to find out the factors that contribute for motor cycle crashes and to study the injury pattern seen in helmeted and non-helmeted victims. MATERIAL AND METHODS Victims of two wheeler accidents brought for autopsy in a Govt. Medical College were studied from October 2010 to August 2011. Two wheelers include motor cycles, scooters and mopeds. Bicycles were excluded from the study. Accidents include all types; against all types of vehicles running on the road, collision with any object, surface or any animal or fall from vehicle. The details of the accident were collected in a printed proforma from relative/witnesses and from police officials. The injuries were entered in the specific columns of proforma. Data was analysed with MS Excel. RESULTS Death due to head injury is more in non-helmeted (52.5% compared to helmeted drivers (43.8 % whereas injury to chest and abdomen and limbs are more in helmeted. Combination of injuries (Head+Chest+Abdomen predominated in helmeted drivers (18.8% compared to 5% in non-helmeted drivers. Spinal injuries were more in helmeted than in non-helmeted. CONCLUSION The pattern of head injury was analysed in detail in helmeted and non-helmeted drivers. This will help in detailing of pattern of head injury in both groups.

The central aim of the research was to examine speeding behavior without helmet wearing among motorcycle riders in Ho Chi Minh City. The research model expanded the Theory of Planned Behavior by both psychological flow theory and sensation-seeking. 268 motorcyclists were involved in the research. A Confirmatory factor analysis and a Structural equation modeling were employed for model specification. The findings indicated a significant effect between predictors and the intention of speeding without helmet wearing. In addition, there was direct relation between intention and actual behavior. Also, sensation-seeking proved to be important in moderating predictors between the low-sensation-seeking motorcyclists and high-sensation-seeking ones. A deeper understanding of why motorcycle riders exceed the speed limit without wearing helmet played key role in changing their behavior.

To evaluate comfort and noise intensity using the COMFORT scale in infants who receive respiratory support with a helmet interface. An observational descriptive study was conducted on all infants (1 to 12 months of age) admitted to a PICU from November 1st 2013 to March 31st 2014 and who received non-invasive ventilation with a helmet interface. Tolerance to the interface was assessed by use of the COMFORT scale. The intensity of the noise to which the infants were exposed was measured with a TES1350A HIBOK 412 sound-level meter. Three measurements were made every day. Twenty seven patients with bronchiolitis (median age: 54 days; range: 10 to 256) were included. Median COMFORT score in the first day was 21 points (14 - 28). An increase in patient comfort was found with a gradual decrease in the scores, with a maximum reduction of 22% from the first hours (score of 22) to the fifth day (score of 18). The minimum sound intensity registered was 42dB, and the maximum was 78dB. Background noise intensity was associated with noise intensity in the helmet. No differences were observed in COMFORT score and noise intensity between ventilator devices. Helmet interface was well tolerated by infants. COMFORT score results are an indicator that infants were comfortable or very comfortable. The measured noise intensity was in the safe range permitted by World Health Organization.

The objective of this research is to develop an application for enforcing helmet wearing using CCTV cameras. The developed application aims to help law enforcement by police, and eventually resulting in changing risk behaviours and consequently reducing the number of accidents and its severity. Conceptually, the application software implemented using C++ language and OpenCV library uses two different angle of view CCTV cameras. Video frames recorded by the wide-angle CCTV camera are used to detect motorcyclists. If any motorcyclist without helmet is found, then the zoomed (narrow-angle) CCTV is activated to capture image of the violating motorcyclist and the motorcycle license plate in real time. Captured images are managed by database implemented using MySQL for ticket issuing. The results show that the developed program is able to detect 81% of motorcyclists on various motorcycle types during daytime and night-time. The validation results reveal that the program achieves 74% accuracy in detecting the motorcyclist without helmet.

The role of consent in medical research: breaking or building walls? A call for legislative reform.

Science.gov (United States)

Dangata, Yohanna Yanshiyi

2011-12-01

Research has been integral to the practice of medicine for almost as long as the discipline has existed. Until fairly recently research used to be conducted on human subjects without mandatory requirement for their consent. However, over time medical research became associated with significant cruelty resulting in an outcry for regulation of research actives. This resulted in significant legislation in place for monitoring. Today it is mandatory to obtain consent from subjects before embarking on medical research, and indeed treatment. Its significant regulatory role notwithstanding, the issue of consent at times becomes a hindrance to research. This paper examines the issue of consent in relation to medical research in the context of present legislation. It lays out the background to medical research with respect to purpose, scope, standard protocol and related issues; it then addresses the issue of consent in various scenarios, highlighting problems and the need for legislative reform. It is maintained that while regulatory measures have brought a lot of sanity to medical research and the medical profession, some measures are building walls inhibitory to research activities. Research being integral to the development and growth of healthcare delivery, there is need for reformation of current medical law for balance between patient protectionism and progress in medical research for effective patient care.

To evaluate optimal humidifier water temperature when using a helmet for noninvasive ventilation. Twenty-eight healthy individuals underwent 8 cm H2O CPAP ventilation with FIO2 of 0.21 and 0.5. Each was sequentially tested in the following order: using the helmet without humidification at ambient temperature; with humidification with unheated chamber water; and with humidification with the chamber water at 31°C, 34°C, and 37°C. At each setting, after a 20 min stabilization period, measurements were taken. Comfort level at each setting was evaluated using a visual analog scale rated zero (least comfortable) to 10 (most comfortable). Temperature and relative and absolute humidity inside the helmet increased; however, the comfort scores significantly decreased as the humidification chamber water temperature increased. Regardless of the FIO2, statistically significantly highest comfort scores were obtained when humidification water, with and without active humidification, was at ambient temperature. Unacceptable absolute humidity was obtained only without humidification at room temperature when FIO2 was 0.5. With the clinical use of a helmet, for patient comfort and mucosal humidification during CPAP, the most desirable conditions are likely to be obtained by humidifying without heating, that is by leaving the water in the humidifier chamber at room temperature.

Full Text Available Abstract Background In The Netherlands, helmet therapy is a commonly used treatment in infants with skull deformation (deformational plagiocephaly or deformational brachycephaly. However, evidence of the effectiveness of this treatment remains lacking. The HEADS study (HElmet therapy Assessment in Deformed Skulls aims to determine the effects and costs of helmet therapy compared to no helmet therapy in infants with moderate to severe skull deformation. Methods/design Pragmatic randomised controlled trial (RCT nested in a cohort study. The cohort study included infants with a positional preference and/or skull deformation at two to four months (first assessment. At 5 months of age, all children were assessed again and infants meeting the criteria for helmet therapy were asked to participate in the RCT. Participants were randomly allocated to either helmet therapy or no helmet therapy. Parents of eligible infants that do not agree with enrolment in the RCT were invited to stay enrolled for follow up in a non-randomisedrandomised controlled trial (nRCT; they were then free to make the decision to start helmet therapy or not. Follow-up assessments took place at 8, 12 and 24 months of age. The main outcome will be head shape at 24 months that is measured using plagiocephalometry. Secondary outcomes will be satisfaction of parents and professionals with the appearance of the child, parental concerns about the future, anxiety level and satisfaction with the treatment, motor development and quality of life of the infant. Finally, compliance and costs will also be determined. Discussion HEADS will be the first study presenting data from an RCT on the effectiveness of helmet therapy. Outcomes will be important for affected children and their parents, health care professionals and future treatment policies. Our findings are likely to influence the reimbursement policies of health insurance companies. Besides these health outcomes, we will be able to

This paper reports on predictors of helmet use behaviour, using variables based on the theory of planned behaviour model among the employed motorcycle riders in Yazd-Iran, in an attempt to identify influential factors that may be addressed through intervention efforts. In 2007, a cluster random sample of 130 employed motorcycle riders in the city of Yazd in central Iran, participated in the study. Appropriate instruments were designed to measure the variables of interest (attitude, subjective norms, perceived behaviour control, intention along with helmet use behaviour). Reliability and validity of the instruments were examined and approved. The statistical analysis of the data included descriptive statistics, bivariate correlations, and multiple regression. Based on the results, 56 out of all the respondents (43.1%) had history of accident by motorcycle. Of these motorcycle riders only 10.7% were wearing their helmet at the time of their accident. Intention and perceived behavioural control showed a significant relationship with helmet use behaviour and perceived behaviour control was the strongest predictor of helmet use intention, followed by subjective norms, and attitude. It was found that that helmet use rate among motorcycle riders was very low. The findings of present study provide a preliminary support for the TPB model as an effective framework for examining helmet use in motorcycle riders. Understanding motorcycle rider's thoughts, feelings and beliefs about helmet use behaviour can assist intervention specialists to develop and implement effective programs in order to promote helmet use among motorcycle riders.

Rice, Thomas M; Troszak, Lara; Ouellet, James V; Erhardt, Taryn; Smith, Gordon S; Tsai, Bor-Wen

2016-06-01

Most studies find strong evidence that motorcycle helmets protect against injury, but a small number of controversial studies have reported a positive association between helmet use and neck injury. The most commonly cited paper is that of Goldstein (1986). Goldstein obtained and reanalyzed data from the Hurt Study, a prospective, on-scene investigation of 900 motorcycle collisions in the city of Los Angeles. The Goldstein results have been adopted by the anti-helmet community to justify resistance to compulsory motorcycle helmet use on the grounds that helmets may cause neck injuries due to their mass. In the current study, we replicated Goldstein's models to understand how he obtained his unexpected results, and we then applied modern statistical methods to estimate the association of motorcycle helmet use with head injury, fatal injury, and neck injury among collision-involved motorcyclists. We found Goldstein's analysis to be critically flawed due to improper data imputation, modeling of extremely sparse data, and misinterpretation of model coefficients. Our new analysis showed that motorcycle helmets were associated with markedly lower risk of head injury (RR 0.40, 95% CI 0.31-0.52) and fatal injury (RR 0.44, 95% CI 0.26-0.74) and with moderately lower but statistically significant risk of neck injury (RR 0.63, 95% CI 0.40-0.99), after controlling for multiple potential confounders.

Erhardt, Taryn; Rice, Thomas; Troszak, Lara; Zhu, Motao

2016-01-01

The use of novelty motorcycle helmets is often prompted by beliefs that wearing a standard helmet can contribute to neck injury during traffic collisions. The goal of this analysis was to examine the association between helmet type and neck injury risk and the association between helmet type and head injury. Data were collected during the investigation of motorcycle collisions of any injury severity by the California Highway Patrol (CHP) and 83 local law enforcement agencies in California between June 2012 and July 2013. We estimated head injury and neck injury risk ratios from data on 7051 collision-involved motorcyclists using log-binomial regression. Helmet type was strongly associated with head injury occurrence but was not associated with the occurrence of neck injury. Rider age, rider alcohol use, and motorcycle speed were strong, positive predictors of both head and neck injury. Interventions to improve motorcycle helmet choice and to counteract misplaced concerns surrounding neck injury risk are likely to lead to reductions in head injury, brain injury, and death.

Full Text Available The article discusses iron helmet (No. 36.25.115, which is stored in the Metropolitan Museum of art (New York City, United States. For the first time this helmet was published and analyzed by American scientists G. C. Stone and D.G. Alexander. The analysis showed that the Bowl was made by Turkish masters of the XVII century and backplate and the hoop is added to the helmet in 1781–1782 D.G. Alexander speculated that the helmet belonged to the Warrior of the Crimean Khanate. Dating the helmet does not raise objections. However, the attribution of a helmet requires some clarification. Analysis of the design of the helmet and decoration revealed that backplate, hoop and Aventail from iron rings added to Bowl in 1781–1782, were manufactured by Circassian craftsmen living in the Northern Caucasus or in Crimea. For the decoration of the helmet has been used typical Circassian ornaments: "sieve", cherkessian floral pattern, geometric shapes, triangular in shape, "gear", etc. During Assembly of the helmet were applied characteristic of Circassian gunsmiths technological solutions: using as a basis the bowl old-style helmet, tapered Finial with a ring for a decorative plume, hoop with four plates, ringed with aventail lip to protect the forehead, etc. In Circassia similar headgear worn were known as tang (from the Arabic.

Inhaled nitric oxide (NO) may have a role in the treatment of preterm infants with respiratory failure. We evaluated the feasibility of administering NO therapy by a new continuous positive airway pressure (CPAP) system (neonatal helmet-CPAP). While maintaining a constant total flow of 8, 10, and 12 l.min(-1), NO concentrations were progressively increased to 5, 10, 20, and 40 p.p.m. in the neonatal helmet-CPAP pressure chamber (5 cmH2O). NO, NO2, and O2 concentrations were measured in the pressure chamber and the immediate external environment. In the chamber, NO2 levels remained low (neonatal helmet-CPAP system. This method allows the delivery of accurate NO levels and high O2 concentrations avoiding NO2 accumulation. Further experimental and clinical studies are needed.

The goal of this study is to determine if a difference in societal costs exists from traumatic brain injuries (TBI) in patients who wear helmets compared to non-wearers. This is a retrospective cost-of-injury study of 128 patients admitted to the Montreal General Hospital (MGH) following a TBI that occurred while cycling between 2007-2011. Information was collected from Quebec Trauma Registry. The independent variables collected were socio-demographic, helmet status, clinical and neurological patient information. The dependent variables evaluated societal costs. The median costs of hospitalization were significantly higher (p = 0.037) in the no helmet group ($7246.67 vs. $4328.17). No differences in costs were found for inpatient rehabilitation (p = 0.525), outpatient rehabilitation (p = 0.192), loss of productivity (p = 0.108) or death (p = 1.000). Overall, the differences in total societal costs between the helmet and no helmet group were not significantly different (p = 0.065). However, the median total costs for patients with isolated TBI in the non-helmet group ($22, 232.82) was significantly higher (p = 0.045) compared to the helmet group ($13, 920.15). Cyclists sustaining TBIs who did not wear helmets in this study were found to cost society nearly double that of helmeted cyclists.

Phillips, Elyse; Gazmararian, Julie

To determine whether specific state legislation has an effect on opioid overdose mortality rates compared to states without those types of legislation. Ecological study estimating opioid-related mortality in states with and without a prescription drug monitoring program (PDMP) and/or medical cannabis legislation. Opioid-related mortality rates for 50 states and Washington DC from 2011 to 2014 were obtained from CDC WONDER. PDMP data were obtained from the National Alliance for Model State Drug Laws, and data on medical cannabis legislation from the National Organization for the Reform of Marijuana Laws. The relationship between PDMPs with mandatory access provisions, medical cannabis legislation, and opioid-related mortality rates. Multivariate repeated measures analysis performed with software and services. Medical cannabis laws were associated with an increase of 21.7 percent in mean age-adjusted opioid-related mortality (p cannabis (p = 0.049) and 5.8 percent for states with a PDMP (p = 0.005). Interaction between both types of legislation produced a borderline significant decrease of 10.1 percent (p = 0.055). For every year states had both types of legislation, interaction resulted in a 0.6 percent decrease in rate (p = 0.013). When combined with the availability of medical cannabis as an alternative analgesic therapy, PDMPs may be more effective at decreasing opioid-related mortality.

The aim of this study was to examine the effect of helmet use on non-head-neck injury severity and crash circumstances in skiers and snowboarders. We used a matched case-control study over the November 2001 to April 2002 winter season. 3295 of 4667 injured skiers and snowboarders reporting to the ski patrol at 19 areas in Quebec with non-head, non-neck injuries agreed to participate. Cases included those evacuated by ambulance, admitted to hospital, with restriction of normal daily activities (NDAs) >6 days, with non-helmet equipment damage, fast self-reported speed, participating on a more difficult run than usual, and jumping-related injury. Controls were injured participants without severe injuries or high-energy crash circumstances and were matched to cases on ski area, activity, day, age, and sex. Conditional logistic regression was used to relate each outcome to helmet use. There was no evidence that helmet use increased the risk of severe injury or high-energy crash circumstances. The results suggest that helmet use in skiing and snowboarding is not associated with riskier activities that lead to non-head-neck injuries.

Rapid urbanization and motorization without corresponding increases in helmet usage have made traumatic brain injury due to road traffic accidents a major public health crisis in Cambodia. This analysis was conducted to quantify the impact of helmets on severity of injury, neurosurgical indication, and functional outcomes at discharge for motorcycle operators who required hospitalization for a traumatic brain injury following a road traffic accident in Cambodia. The medical records of 491 motorcycle operators who presented to a major tertiary care center in Cambodia with traumatic brain injury were retrospectively analyzed using multivariate logistic regression. The most common injuries at presentation were contusions (47.0%), epidural hematomas (30.1%), subdural hematomas (27.9%), subarachnoid hemorrhages (12.4%), skull fractures (21.4%), and facial fractures (18.5%). Moderate-to-severe loss of consciousness was present in 36.3% of patients. Not wearing a helmet was associated with an odds ratio of 2.20 (95% confidence interval [CI], 1.15-4.22) for presenting with moderate to severe loss of consciousness compared to helmeted patients. Craniotomy or craniectomy was indicated for evacuation of hematoma in 20.0% of cases, and nonhelmeted patients had 3.21-fold higher odds of requiring neurosurgical intervention (95% CI, 1.25-8.27). Furthermore, lack of helmet usage was associated with 2.72-fold higher odds of discharge with functional deficits (95% CI, 1.14-6.49). In total, 30.1% of patients were discharged with severe functional deficits. Helmets demonstrate a protective effect and may be an effective public health intervention to significantly reduce the burden of traumatic brain injury in Cambodia and other developing countries with increasing rates of motorization across the world.

Urban public bicycle sharing programs are on the rise in the United States. Launched in 2013, NYC's public bicycle share program, Citi Bike™ is the fastest growing program of its kind in the nation, with nearly 100,000 members and more than 330 docking stations across Manhattan and Brooklyn. The purpose of this study was to assess helmet use behavior among Citi Bike™ riders at 25 of the busiest docking stations. The 25 Citi Bike™ Stations varied greatly in terms of usage: total number of cyclists (N = 96-342), commute versus recreation (22.9-79.5% commute time riders), weekday versus weekend (6.0-49.0% weekend riders). Helmet use ranged between 2.9 and 29.2% across sites (median = 7.5 %). A total of 4,919 cyclists were observed, of whom 545 (11.1%) were wearing helmets. Incoming cyclists were more likely to wear helmets than outgoing cyclists (11.0 vs 5.9%, p = .000). NYC's bike share program endorses helmet use, but relies on education to encourage it. Our data confirm that, to date, this strategy has not been successful.

We use computational simulations to compare the impact response of different football and U.S. Army helmet pad materials. We conduct experiments to characterise the material response of different helmet pads. We simulate experimental helmet impact tests performed by the U.S. Army to validate our methods. We then simulate a cylindrical impactor striking different pads. The acceleration history of the impactor is used to calculate the head injury criterion for each pad. We conduct sensitivity studies exploring the effects of pad composition, geometry and material stiffness. We find that (1) the football pad materials do not outperform the currently used military pad material in militarily relevant impact scenarios; (2) optimal material properties for a pad depend on impact energy and (3) thicker pads perform better at all velocities. Although we considered only the isolated response of pad materials, not entire helmet systems, our analysis suggests that by using larger helmet shells with correspondingly thicker pads, impact-induced traumatic brain injury may be reduced.

Bicycle injuries are of concern in Canada. Since helmet use was mandated in 1996 in the province of British Columbia, Canada, use has increased and head injuries have decreased. Despite the law, many cyclists do not wear a helmet. Health action process approach (HAPA) model explains intention and behaviour with self-efficacy, risk perception, outcome expectancies and planning constructs. The present study examines the impact of a social marketing campaign on HAPA constructs in the context of bicycle helmet use. A questionnaire was administered to identify factors determining helmet use. Intention to obey the law, and perceived risk of being caught if not obeying the law were included as additional constructs. Path analysis was used to extract the strongest influences on intention and behaviour. The social marketing campaign was evaluated through t-test comparisons after propensity score matching and generalised linear modelling (GLM) were applied to adjust for the same covariates. 400 cyclists aged 25-54 years completed the questionnaire. Self-efficacy and Intention were most predictive of intention to wear a helmet, which, moderated by planning, strongly predicted behaviour. Perceived risk and outcome expectancies had no significant impact on intention. GLM showed that exposure to the campaign was significantly associated with higher values in self-efficacy, intention and bicycle helmet use. Self-efficacy and planning are important points of action for promoting helmet use. Social marketing campaigns that remind people of appropriate preventive action have an impact on behaviour. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Rahman, Anis; Rahman, Aunik K.

2015-05-01

High speed acquisition of reflected terahertz energy constitutes a kinetics spectrum that is an effective tool for layered materials' deformation characterization under ballistic impact. Here we describe utilizing the kinetics spectrum for quantifying a deformation event due to impact in material used for Soldier's helmet. The same technique may be utilized for real-time assessment of trauma by measuring the helmet wore by athletes. The deformation of a laminated material (e.g., a helmet) is dependent on the nature of impact and projectile; thus can uniquely characterize the impact condition leading to a diagnostic procedure based on the energy received by an athlete during an impact. We outline the calibration process for a given material under ballistic impact and then utilize the calibration for extracting physical parameters from the measured kinetics spectrum. Measured kinetics spectra are used to outline the method and rationale for extending the concept to a diagnosis tool. In particular, captured kinetics spectra from multilayered plates subjected to ballistic hit under experimental conditions by high speed digital acquisition system. An algorithm was devised to extract deformation and deformation velocity from which the energy received on the skull was estimated via laws of nonrelativistic motion. This energy is assumed to be related to actual injury conditions, thus forming a basis for determining whether the hit would cause concussion, trauma, or stigma. Such quantification may be used for diagnosing a Soldier's trauma condition in the field or that of an athlete's.

Context: Most research on face mask removal has been performed on unused equipment. Objective: To identify and compare factors that influence the condition of helmet components and their relationship to face mask removal. Design: A cross-sectional, retrospective study. Setting: Five athletic equipment reconditioning/recertification facilities. Participants: 2584 helmets from 46 high school football teams representing 5 geographic regions. Intervention(s): Helmet characteristics (brand, model, hardware components) were recorded. Helmets were mounted and face mask removal was attempted using a cordless screwdriver. The 2004 season profiles and weather histories were obtained for each high school. Main Outcome Measure(s): Success and failure (including reason) for removal of 4 screws from the face mask were noted. Failure rates among regions, teams, reconditioning year, and screw color (type) were compared. Weather histories were compared. We conducted a discriminant analysis to determine if weather variables, region, helmet brand and model, reconditioning year, and screw color could predict successful face mask removal. Metallurgic analysis of screw samples was performed. Results: All screws were successfully removed from 2165 (84%) helmets. At least 1 screw could not be removed from 419 (16%) helmets. Significant differences were found for mean screw failure per helmet among the 5 regions, with the Midwest having the lowest failure rate (0.08 ± 0.38) and the Southern (0.33 ± 0.72), the highest. Differences were found in screw failure rates among the 46 teams (F1,45 = 9.4, P < .01). Helmets with the longest interval since last reconditioning (3 years) had the highest failure rate, 0.47 ± 0.93. Differences in success rates were found among 4 screw types (χ21,4 = 647, P < .01), with silver screws having the lowest percentage of failures (3.4%). A discriminant analysis (Λ = .932, χ214,n=2584 = 175.34, P < .001) revealed screw type to be the strongest predictor of

NIV is increasingly used for prevention and treatment of respiratory complications and failure. Some of them are admitted to the PACU with advanced hemodynamic monitors which allow quantification of Extravascular Lung Water (EVLW) by transpulmonary thermodilution technique (TPTD) and Pulmonary Vascular Permeability (PVP) providing information on lung edema. The objective of this study was to ascertain if EVLW Index and PVP Index may predict failure (intubation) or success (non-intubation) in patients developing acute respiratory failure (ARF) in the postoperative period following major abdominal surgery, where the first line of treatment was non-invasive continuous positive airway pressure via a helmet. Hemodynamic variables, EVLWI and PVPI were monitored with a transpulmonary thermodilution hemodynamic monitor device (PiCCO™) before and after the application of CPAP. Avoidance of intubation was observed in 66% of patients with Helmet-CPAP. In these patients after the first hour of application of CPAP, PaO2/FiO2 ratio significantly increased (303.33±65.2 vs. 141.6±14.6, P<.01). Before starting Helmet-CPAP values of EVLWI and PVPI were significantly lower in non-intubated patients (EVLWI 8.6±1.08 vs. 11.8±0.99ml/kg IBW, P<.01 and PVPI 1.7±0.56 vs. 3.0±0.88, P<.01). An optimal cut-off value for EVLWI was established at 9.5, and at 2.45 for PVPI (sensitivity of 0.7; specificity of 0.9, P<.01). In this type of patient the physiological parameters that predict the failure of Helmet-CPAP with the greatest accuracy were the value of the EVLWI and PVPI before Helmet-CPAP institution and the PaO2/FiO2 ratio and the respiratory rate after one hour of CPAP.

Full Text Available Blast-induced traumatic brain injury has emerged as a signature injury in combat casualty care. Present combat helmets are designed primarily to protect against ballistic and blunt impacts, but the current issue with helmets is protection concerning blasts. In order to delineate the blast wave attenuating capability of the Advanced Combat Helmet (ACH, a finite element (FE study was undertaken to evaluate the head response against blast loadings with and without helmet using a partially validated FE model of the human head and ACH. Four levels of overpressures (0.27-0.66 MPa from the Bowen’s lung iso-damage threshold curves were used to simulate blast insults. Effectiveness of the helmet with respect to head orientation was also investigated. The resulting biomechanical responses of the brain to blast threats were compared for human head with and without the helmet. For all Bowen’s cases, the peak intracranial pressures (ICP in the head ranged from 0.68-1.8 MPa in the coup cortical region. ACH was found to mitigate ICP in the head by 10-35%. Helmeted head resulted in 30% lower average peak brain strains and product of strain and strain rate. Among three blast loading directions with ACH, highest reduction in peak ICP (44% was due to backward blasts whereas the lowest reduction in peak ICP and brain strains was due to forward blast (27%. The biomechanical responses of a human head to primary blast insult exhibited directional sensitivity owing to the different geometry contours and coverage of the helmet construction and asymmetric anatomy of the head. Thus, direction-specific tolerances are needed in helmet design in order to offer omni-directional protection for the human head. The blasts of varying peak overpressures and durations that are believed to produce the same level of lung injury produce different levels of mechanical responses in the brain, and hence "iso-damage" curves for brain injury are likely different than the Bowen curves

Traumatic brain injury is a major cause of morbidity and mortality worldwide, often necessitating neurosurgical intervention to evacuate intracranial bleeding. Since the early 2000s, Cambodia has been undergoing a rapid increase in motorcycle transit and in road traffic accidents, but the prevalence of helmet usage remains low. Epidural hematomas are severe traumatic brain injuries that can necessitate neurosurgical intervention. This is a retrospective cohort study of patients with epidural hematoma secondary to motorcycle accidents who presented to a major national tertiary care center in Phnom Penh, Cambodia, between November 2013 and March 2016. All patients were diagnosed with computed tomography of the head. In this cohort, 21.6% of patients in motorcycle accidents presented with epidural hematoma and 89.1% of patients were men, 47.6% were intoxicated, and were 87.8% were not wearing helmets at the moment of impact. Not wearing a helmet was associated with a 6.90-fold increase in odds of presenting with a moderate-to-severe Glasgow coma scale score and a 3.76-fold increase in odds of requiring craniotomy or craniectomy for evacuation of hematoma. Male sex was also associated with increased odds of higher clinical severity at presentation and indication for craniotomy or craniectomy, and alcohol intoxication at the time of accident was not associated with either. Helmet usage is protective in reducing the severity of presentation and need for neurosurgical intervention for patients with epidural hematoma secondary to motorcycle accidents.

The hottest months on northern Australian cattle stations are from September to November, and it is during these months that horseback cattle mustering occurs. Stockmen wear clothing that restricts heat loss, and protective helmets have recently been introduced. Anecdotal evidence points to the possibility that helmets may increase the probability of developing heat illness, or reducing workplace performance. In this project, we quantified the working (thermal) environment on such cattle stations, and measured the metabolic demands on, and concurrent physiological strain in stockmen during mustering, whilst wearing an equestrian helmet. During horseback work, the average heart rate was 102.0 beats min(-1) (SD 14.0), with almost 90% of the time (238 min) spent working at intensities <50% of the heart rate reserve. The projected metabolic heat production during mustering ranged between 178 and 333 W (women), and between 212 and 542 W (men). The average core temperature was 37.6 degrees C, while the mean skin temperature averaged 34.1 degrees C. It was concluded that the working environment is, on average, thermally uncompensable during the mustering season. However, horseback mustering per se is a relatively low-intensity activity, interspersed with short periods of high-intensity work. This activity level was reflected within core temperatures, which rarely climbed above values associated with light-moderate exercise. Thus, whilst the climatic state was uncompensable, stockmen used behavioural strategies to minimise the risk of heat illness. Finally, it was observed that the helmet, though unpleasant to wear, did not appear to increase thermal strain in a manner that would disadvantage stockmen.

The rapid development of Internet of Things and the related sensor technology requires sustainable power sources for their continuous operation. Scavenging and utilizing the ambient environmental energy could be a superior solution. Here, we report a self-powered helmet for emergency, which was powered by the energy converted from ambient mechanical vibration via a hybridized nanogenerator that consists of a triboelectric nanogenerator (TENG) and an electromagnetic generator (EMG). Integrating with transformers and rectifiers, the hybridized nanogenerator can deliver a power density up to 167.22 W/m(3), which was demonstrated to light up 1000 commercial light-emitting diodes (LEDs) instantaneously. By wearing the developed safety helmet, equipped with rationally designed hybridized nanogenerator, the harvested vibration energy from natural human motion is also capable of powering a wireless pedometer for real-time transmitting data reporting to a personal cell phone. Without adding much extra weight to a commercial one, the developed wearing helmet can be a superior sustainable power source for explorers, engineers, mine-workers under well, as well as and disaster-relief workers, especially in remote areas. This work not only presents a significant step toward energy harvesting from human biomechanical movement, but also greatly expands the applicability of TENGs as power sources for self-sustained electronics.

Noninvasive continuous positive airway pressure (CPAP) is usually applied with a nasal or facial mask to treat mild acute respiratory failure (ARF) in infants. A pediatric helmet has now been introduced in clinical practice to deliver CPAP. This study compared treatment failure rates during CPAP delivered by helmet or facial mask in infants with respiratory syncytial virus-induced ARF. In this multicenter randomized controlled trial, 30 infants with respiratory syncytial virus-induced ARF were randomized to receive CPAP by helmet (n = 17) or facial mask (n = 13). The primary endpoint was treatment failure rate (defined as due to intolerance or need for intubation). Secondary outcomes were CPAP application time, number of patients requiring sedation, and complications with each interface. Compared with the facial mask, CPAP by helmet had a lower treatment failure rate due to intolerance (3/17 [17%] vs 7/13 [54%], P = .009), and fewer infants required sedation (6/17 [35%] vs 13/13 [100%], P = .023); the intubation rates were similar. In successfully treated patients, CPAP resulted in better gas exchange and breathing pattern with both interfaces. No major complications due to the interfaces occurred, but CPAP by mask had higher rates of cutaneous sores and leaks. These findings confirm that CPAP delivered by helmet is better tolerated than CPAP delivered by facial mask and requires less sedation. In addition, it is safe to use and free from adverse events, even in a prolonged clinical setting. Copyright © 2015 by the American Academy of Pediatrics.

Football players can receive up to 1400 head impacts per season, averaging 6.3 impacts per practice and 14.3 impacts per game. A decrease in the capacity of a helmet to manage linear acceleration with multiple impacts could increase the risk of traumatic brain injury. To investigate the ability of football helmets to manage linear acceleration with multiple high-energy impacts. Descriptive laboratory study. Laboratory. We collected linear-acceleration data for 100 impacts at 6 locations on 4 helmets of different models currently used in football. Impacts 11 to 20 were compared with impacts 91 to 100 for each of the 6 locations. Linear acceleration was greater after multiple impacts (91-100) than after the first few impacts (11-20) for the front, front-boss, rear, and top locations. However, these differences are not clinically relevant as they do not affect the risk for head injury. American football helmet performance deteriorated with multiple impacts, but this is unlikely to be a factor in head-injury causation during a game or over a season.

Transportation by motorcycle and bicycle has become popular in Taiwan, this study was designed to investigate the protective effect of helmet use during motorcycle and bicycle accidents by using a propensity score-matched study based on trauma registry system data. Data of adult patients hospitalized for motorcycle or bicycle accidents between January 1, 2009 and December 31, 2015 were retrieved from the Trauma Registry System. These included 7735 motorcyclists with helmet use, 863 motorcyclists without helmet use, 76 bicyclists with helmet use, and 647 bicyclists without helmet use. The primary outcome measurement was in-hospital mortality. Secondary outcomes were the hospital length of stay (LOS), intensive care unit (ICU) admission rate, and ICU LOS. Normally distributed continuous data were analyzed by the unpaired Student t-test, and non-normally distributed data were compared using the Mann-Whitney U-test. Two-sided Fisher exact or Pearson chi-square tests were used to compare categorical data. Propensity score matching (1:1 ratio using optimal method with a 0.2 caliper width) was performed using NCSS software, adjusting for the following covariates: sex, age, and comorbidities. Further logistic regression was used to evaluate the effect of helmet use on mortality rates of motorcyclists and bicyclists, respectively. The mortality rate for motorcyclists with helmet use (1.1%) was significantly lower than for motorcyclists without helmet use (4.2%; odds ratio [OR] 0.2; 95% confidence interval [CI]: 0.17-0.37; p Motorcycle helmets provide protection to adult motorcyclists involved in traffic accidents and their use is associated with a decrease in mortality rates and the risk of head injuries. However, no such protective effect of helmet use was observed for bicyclists involved in collisions.

Full Text Available Gameplay is commonly considered to be a voluntary activity. Game designers generally believe that voluntary gameplay is essentially different from mandatory gameplay. Such a belief may be a challenge for serious games, as instruction is usually mandatory. The article describes the outcomes of two experiments on the impact of voluntariness on the learning effect and enjoyment of a serious game. In the first experiment freedom of choosing to play a serious game was studied, with participants who had volunteered to participate. The results suggested that, contrary to the opinion of many game designers, being required to play a serious game does not automatically take the fun out of the game. The second experiment had voluntary participants and mandatory participants, who had to participate as part of a homework assignment. The outcomes show that mandatory participants enjoyed the game as much as the voluntary participants, even if they had to play the game for a minimum required time. These studies indicate that mandatory gameplay does not reduce enjoyment and learning effect.

Full Text Available Introduction: One of the problems that the delivery of continuous positive airway pressure (CPAP via a helmet poses is the generation of noise. The objective of our study was to assess the effect that the use of filter has on sound pressure levels generated by the delivery of positive airway pressure at different gas flow rates. Materials and Methods: Sound pressure levels generated by neonatal helmet CPAP delivery were measured at different gas flows (20, 30, and 40 l/min with and without a breathing filter. Noise intensity was measured by installing microphones in the inner ear of dummy heads wearing helmets. Results: The sound pressure level increased by 38% at a gas flow of 40 l/min, as compared to a gas flow of 20 l/min {74 dBA [interquartile range (IQR 2,2] vs 52 dBA (IQR 5,9, respectively}. Using the breathing filter as a diffuser has a variety of effects on sound pressure levels according to the gas flow rate. Conclusion: The intensity of the noise generated by helmet delivery of positive airway pressure depends on the type of helmet used, gas flow, and use or not of a diffuser filter. Breathing filters with gas flows over 30 l/min might not be recommended since they would not attenuate but will rather amplify sound pressure.

There is a growing interest in developing brain PET scanners with high sensitivity and high spatial resolution for early diagnosis of neurodegenerative diseases and studies of brain functions. Sensitivity of the PET scanner can be improved by increasing the solid angle. However, conventional PET scanners are designed based on a cylindrical geometry, which may not be the most efficient design for brain imaging in terms of the balance between sensitivity and cost. We proposed a dedicated brain PET scanner based on a hemispheric shape detector and a chin detector (referred to as the helmet-chin PET), which is designed to maximize the solid angle by increasing the number of lines-of-response in the hemisphere. The parallax error, which PET scanners with a large solid angle tend to have, can be suppressed by the use of depth-of-interaction detectors. In this study, we carry out a realistic evaluation of the helmet-chin PET using Monte Carlo simulation based on the 4-layer GSO detector which consists of a 16  ×  16  ×  4 array of crystals with dimensions of 2.8  ×  2.8  ×  7.5 mm3. The purpose of this simulation is to show the gain in imaging performance of the helmet-chin PET compared with the cylindrical PET using the same number of detectors in each configuration. The sensitivity of the helmet-chin PET evaluated with a cylindrical phantom has a significant increase, especially at the top of the (field-of-view) FOV. The peak-NECR of the helmet-chin PET is 1.4 times higher compared to the cylindrical PET. The helmet-chin PET provides relatively low noise images throughout the FOV compared to the cylindrical PET which exhibits enhanced noise at the peripheral regions. The results show the helmet-chin PET can significantly improve the sensitivity and reduce the noise in the reconstructed images.

Prolonged mechanical ventilation is associated with lung injury in preterm infants. In these infants, weaning from synchronized intermittent mandatory ventilation may be delayed by their inability to cope with increased respiratory loads. The addition of pressure support to synchronized intermittent mandatory ventilation can offset these loads and may facilitate weaning. The purpose of this work was to compare synchronized intermittent mandatory ventilation and synchronized intermittent mandatory ventilation plus pressure support in weaning from mechanical ventilation and the duration of supplemental oxygen dependency in preterm infants with respiratory failure. Preterm infants weighing 500 to 1000 g at birth who required mechanical ventilation during the first postnatal week were randomly assigned to synchronized intermittent mandatory ventilation or synchronized intermittent mandatory ventilation plus pressure support. In both groups, weaning followed a set protocol during the first 28 days. Outcomes were assessed during the first 28 days and until discharge or death. There were 107 infants enrolled (53 synchronized intermittent mandatory ventilation plus pressure support and 54 synchronized intermittent mandatory ventilation). Demographic and perinatal data, mortality, and morbidity did not differ between groups. During the first 28 days, infants in the synchronized intermittent mandatory ventilation plus pressure support group reached minimal ventilator settings and were extubated earlier than infants in the synchronized intermittent mandatory ventilation group. Total duration of mechanical ventilation, duration of oxygen dependency, and oxygen need at 36 weeks' postmenstrual age alone or combined with death did not differ between groups. However, infants in synchronized intermittent mandatory ventilation plus pressure support within the 700- to 1000-g birth weight strata had a shorter oxygen dependency. The results of this study suggest that the addition of

Full Text Available Statistics prove that more Indians die in Road traffic related accidents than in wars. Prior to World War II, the death toll across the world used to be very high. It was at this juncture that a Military Neurosurgeon named Hugh Cairns introduced the compulsory wearing of crash helmets and brought about a reduction in mortality by more than 50%. Within a decade of introduction of crash helmets in Britain, the entire world followed suit. The results of his efforts are here for all of us to see. This innovative military neurosurgeon is credited as the one who introduced the concept of mobile neurosurgical units during world war and also the first proponent of usage of penicillin in war. His concepts in war surgery are still followed by militaries across the world. This article comes as a tribute to this great Neurosurgeon who helped in saving millions of lives.

Deformational plagiocephaly (DP) is a multifactorial non-synostotic cranial deformity with a reported incidence as high as 1 in 7 infants in North America. Treatment options have focused on non-operative interventions including head repositioning and the use of an orthotic helmet device. Previous studies have used linear and two dimensional outcome measures to assess changes in cranial symmetry after helmet therapy. Our objective was to demonstrate improvement in head shape after treatment with a cranial molding helmet by using Root Mean Square (RMS), a measure unique to 3D photogrammetry, which takes into account both changes in volume and shape over time. Three dimensional photographs were obtained before and after molding helmet treatment in 40 infants (4-10 months old) with deformational plagiocephaly. Anatomical reference planes and measurements were recorded using the 3dMD Vultus(®) analysis software. RMS was used to quantify symmetry by superimposing left and right quadrants and calculating the mean value of aggregate distances between surfaces. Over 95% of the patients demonstrated an improvement in symmetry with helmet therapy. Furthermore, when the sample of infants was divided into two treatment subgroups, a statistically significant correlation was found between the age at the beginning of treatment and the change in the RMS value. When helmet therapy was started before 7 months of age a greater improvement in symmetry was seen. This work represents application of the technique of RMS analysis to demonstrate the efficacy of treatment of deformational plagiocephaly with a cranial molding helmet. Copyright © 2014.

The current study aimed to compare the efficacy and safety of 2 noninvasive respiratory support methods, which included helmet CPAP and high-flow nasal cannula (HFNC) in children with respiratory distress admitted to a pediatric intermediate care unit. This study was a prospective observational study conducted on children with respiratory distress (age 1-24 months) who were admitted to our acute and emergency operative unit. All included subjects were randomly treated with helmet CPAP or HFNC in a 1:1 fashion until their clinical picture, oxygen saturation, and arterial blood gas (ABG) parameters resolved. The efficiencies of helmet CPAP and HFNC were evaluated by breathing frequency, S pO 2 , ABG pH, ABG P aCO 2 , ABG P aO 2 , and P aO 2 /F IO 2 , recorded once at baseline and then after 1 and 6 h of treatment. Both noninvasive respiratory support modalities were compared with a control group of subjects with respiratory distress under standard therapeutic pharmaceutical protocols. We found that both helmet CPAP and HFNC were efficient in improving the clinical conditions of subjects with mild-to-moderate respiratory distress, although clinical response to helmet CPAP was more efficient and rapid compared with HFNC. Children who received respiratory support had a better clinical course in terms of hospitalization, days of intravenous rehydration therapy, and days of drug administration compared with the control group ( P CPAP and HFNC in respiratory distress resolution in a pediatric intermediate care setting. It aims to identify the most efficient treatment to avoid pediatric ICU admissions and endotracheal intubation and reduce the administration of drugs and days of hospitalization.

Football helmets used by high school athletes in the United States should meet the National Operating Committee on Standards for Athletic Equipment performance standards. Despite differences in interior padding and exterior shells, all football helmets should provide comparable protection against concussions. Yet, debate continues on whether differences in the rates or severity of concussions exist based on helmet age/recondition status, manufacturer, or model. To investigate whether high school football concussion characteristics varied by helmet age/recondition status, manufacturer, and model. Descriptive epidemiological study. High school football concussion and helmet data were collected from academic years 2008-2009 through 2012-2013 as part of the National High School Sports-Related Injury Surveillance Study. The certified athletic trainers of participating schools submitted athlete-exposure (AE) and injury information weekly. Participating schools reported 2900 football concussions during 3,528,790 AEs for an overall rate of 8.2 concussions per 10,000 AEs. Concussion rates significantly increased from 2008-2009 through 2012-2013 overall (P = .006) as well as in competition (P = .027) and practice (P = .023). Characteristics of concussed football players (ie, mean number of symptoms, specific concussion symptoms, symptom resolution time, and time until return to play) were similar among players wearing new helmets when compared with reconditioned helmets. Fewer players wearing an old/not reconditioned helmet had concussion symptoms resolve within 1 day compared with players wearing a new helmet. Despite differences in the manufacturers and models of helmets worn by all high school football players compared with players who sustained a concussion, the mean number of concussion symptoms, specific concussion symptoms, symptom resolution time, and time until return to play were similar for concussions sustained by football players wearing the most common helmet

Defining Constellation Suit Helmet Field of View Requirements Employing a Mission Segment Based Reduction Process

McFarland, Shane

2009-01-01

Field of view has always been a design feature paramount to helmets, and in particular space suits, where the helmet must provide an adequate field of view for a large range of activities, environments, and body positions. For Project Constellation, a different approach to helmet requirement maturation was utilized; one that was less a direct function of body position and suit pressure and more a function of the mission segment in which the field of view will be required. Through taxonimization of various parameters that affect suited field of view, as well as consideration for possible nominal and contingency operations during that mission segment, a reduction process was employed to condense the large number of possible outcomes to only six unique field of view angle requirements that still captured all necessary variables while sacrificing minimal fidelity.

Bicycling is becoming an increasingly utilized mode of transportation in New York City. Technology-related distracted bicycling and helmet use are behaviors that can impact bike safety. The aims of this study were twofold: (1) to determine rates and types of technology-related distracted behaviors among bicyclists in the borough of Manhattan in New York City; and (2) to assess the rate of bicycle helmet use among these cyclists. Bicyclists in five popular riding areas in Manhattan were observed for a total of 50 h using a digital video camera during summer months in 2014. Videos were coded and enumerated for the total number and gender of cyclists, type of bicycle, number wearing headphones/earbuds and/or using a mobile phone, and whether the cyclist was wearing a helmet. Almost 25,000 cyclists were observed across the five selected locations (n = 24,861). Riders were almost four times more likely not to wear a helmet on rental bikes as compared with non-rentals (Citi Bike(®) OR 3.8; 95% CI 2.5, 5.9: other rental OR 3.8; 95% CI 3.0, 4.9). Significantly increased odds of not wearing a helmet were observed for females relative to males (OR 1.4; 95% CI 1.1, 1.8) across varied times and locations. Overall, rates of technology-related distraction were low, with headphone use being most prevalent. Males were more likely to wear headphones/earbuds (OR 2.0; 95% CI 1.4, 2.9), as were cyclists on Citi Bikes relative to other rental bikes (OR 2.2; 95% CI 1.3, 3.6). Findings from this study contribute to the growing literature on distracted biking and helmet use among bike share program riders and other cyclists and can inform policymakers and program planners aiming to improve bicycle safety in urban settings.

SYMPATHETIC FILAMENT ERUPTIONS FROM A BIPOLAR HELMET STREAMER IN THE SUN

International Nuclear Information System (INIS)

2012-01-01

On 2005 August 5, two solar filaments erupted successively from different confined arcades underlying a common overarching multiple-arcade bipolar helmet streamer. We present detailed observations of these two events and identify them as sympathetic filament eruptions. The first (F1) is a small active-region filament located near the outskirts of the streamer arcade. It underwent a nonradial eruption, initially moving in the interior of the streamer arcade and resulting in an over-and-out coronal mass ejection. The second filament (F2), a larger quiescent one far away from F1, was clearly disturbed during the F1 eruption. It then underwent a very slow eruption and finally disappeared completely and permanently. Because two belt-shaped diffuse dimmings formed along the footprints of the streamer arcade in the first eruption and persisted throughout the complete disappearance of F2, the eruption series are interpreted as sympathetic: the simple expansion of the common streamer arcade forced by the F1 eruption weakened magnetic flux overlying F2 and thus led to its slow eruption, with the dimming formation indicating their physical connection. Our observations suggest that multiple-arcade bipolar helmet-streamer configurations are appropriate to producing sympathetic eruptions. Combined with the recent observations of unipolar-streamer sympathetic events, it appears that a multiple-arcade unipolar or bipolar helmet streamer can serve as a common magnetic configuration for sympathetic eruptions.

Full Text Available BACKGROUND AND AIM: The study aimed to assess the frequency of head and face injuries in motorcyclists who had an accident and to find out the relationship between helmet use and frequency of these injuries. METHODS: A cross-sectional study with multi-stage sampling method provides data on the injured motorcyclists with road accidents. Data came from a registration form which has documented information of each injured person who had a road accident and hospitalized in the biggest hospital of Isfahan University of Medical Sciences, Iran (Al-Zahra. All the registration forms were surveyed for hospitalization period, treatment costs, severity of injury, and date of accident during 2010 (n = 1626. Later, among the list of injured motorcyclists during the last 3 months of the registration form, 125 cases were randomly selected and interviewed by phone regarding occurrence of the head and face injuries and whether wearing helmet during the accident. Confidence intervals (CI, Chi-square, and Phi and Cramer’s correlation coefficient were applied. The ethical approval was provided. RESULTS: Accident by motorcycle was 31.0% of all road accidents. The frequency of motorcycle accidents was higher in the autumn and among 21-25 year olds. The mean period of hospitalization was 4.3 days and the mean of hospital costs was about 9000000 Rials [about 8200 United States dollar (USD, in 2010]. Of motorcyclist, 35.0% reported they were helmeted when they had the accident. The frequency of head and face injuries was 51.0% among all the injured motorcyclists, 22.0% and 78.0% among the helmeted and non-helmeted motorcyclists, respectively (P = 0.009, r = -0.267. CONCLUSION: Motorcycle accidents comprise a large number of road accidents and cause substantial morbidity and financial impact for the community members. Head and face injuries are the most common trauma in motorcyclists, and the injury rate is higher among non-helmeted motorcyclists.

Similarities and differences between on-scalp and conventional in-helmet magnetoencephalography recordings.

Directory of Open Access Journals (Sweden)

Lau M Andersen

Full Text Available The development of new magnetic sensor technologies that promise sensitivities approaching that of conventional MEG technology while operating at far lower operating temperatures has catalysed the growing field of on-scalp MEG. The feasibility of on-scalp MEG has been demonstrated via benchmarking of new sensor technologies performing neuromagnetic recordings in close proximity to the head surface against state-of-the-art in-helmet MEG sensor technology. However, earlier work has provided little information about how these two approaches compare, or about the reliability of observed differences. Herein, we present such a comparison, based on recordings of the N20m component of the somatosensory evoked field as elicited by electric median nerve stimulation. As expected from the proximity differences between the on-scalp and in-helmet sensors, the magnitude of the N20m activation as recorded with the on-scalp sensor was higher than that of the in-helmet sensors. The dipole pattern of the on-scalp recordings was also more spatially confined than that of the conventional recordings. Our results furthermore revealed unexpected temporal differences in the peak of the N20m component. An analysis protocol was therefore developed for assessing the reliability of this observed difference. We used this protocol to examine our findings in terms of differences in sensor sensitivity between the two types of MEG recordings. The measurements and subsequent analysis raised attention to the fact that great care has to be taken in measuring the field close to the zero-line crossing of the dipolar field, since it is heavily dependent on the orientation of sensors. Taken together, our findings provide reliable evidence that on-scalp and in-helmet sensors measure neural sources in mostly similar ways.

It has been shown that road safety laws, such as motorcycle helmet and safety belt laws, have a significant effect in reducing road fatalities. Although an expanding body of literature has documented the effects of these laws on road safety, it remains unclear which factors influence the likelihood that these laws are enacted. This study attempts to identify the factors that influence the decision to enact safety belt and motorcycle helmet laws. Using panel data from 31 countries between 1963 and 2002, our results reveal that increased democracy, education level, per capita income, political stability, and more equitable income distribution within a country are associated with the enactment of road safety laws. © 2012 Society for Risk Analysis.

We compared neonatal helmet continuous positive airway pressure (CPAP) and the conventional nasal Infant Flow driver (IFD) CPAP in the noninvasive assessment of absolute cerebral blood flow (CBF) and relative cerebral blood volume changes (DeltaCBV) by near-infrared spectroscopy. A randomized crossover study in a tertiary referral NICU. Assessment of CBF and DeltaCBV in 17 very low birth weight infants with respiratory distress (median age 5 days) treated with two CPAP devices at a continuous distending pressure of 4 mbar. Neonates were studied for two consecutive 60-min periods with helmet CPAP and with IFD CPAP. Basal chromophore traces enabled DeltaCBV changes to be calculated. CBF was calculated in milliliters per 100 grams per minute from the saturation rise integral and rate of rise O(2)Hb-HHb. Median (range) CBF with helmet CPAP was 27.37 (9.47-48.20) vs. IFD CBF 34.74 (13.59-60.10)(p=0.049) and DeltaCBV 0.15 (0.09-0.28) with IFD and 0.13 (0.07-0.27) with helmet CPAP (NS). Using helmet and IFD CPAP, the neonates showed no difference in mean physiological parameters (transcutaneous carbon dioxide and oxygen tension, pulse oximetry saturation, heart rate, breathing rate, mean arterial blood pressure, desaturation rate, axillary temperature). Assessing CBF and DeltaCBV measured by near-infrared spectroscopy with two CPAP devices revealed no differences in relative blood volume, but CBF was lower with helmet CPAP. Greater active vasoconstriction and/or passive capillary and/or venous vessel compression seem the most likely reason, due to a positive pressure around the head, neck, and shoulders by comparison with the airway pressure.

Firearm mortality is the leading cause of death for young African American males, however, few studies have focused on racial/ethnic minority populations and firearm violence. The National Black Caucus of State Legislators advocates for legislation that promotes the health of African Americans. Thus, the purpose of this study was to collect baseline data on African American legislators' perceptions regarding firearm violence in the African American community. A cross-sectional study of African American legislators (n = 612) was conducted to investigate the research questions. Of the 612 questionnaires mailed, 12 were not deliverable, and 170 were returned (28%). Utilizing a three wave mailing process, African American legislators were invited to participate in the study. The majority (88%) of respondents perceived firearm violence to be very serious among African Americans. Few (10%) legislators perceived that addressing legislative issues would be an effective strategy in reducing firearm violence among African Americans. The majority (72%) of legislators perceived the most effective strategy to reducing firearm violence in the African American community should focus on addressing societal issues (e.g. crime and poverty). After adjusting for the number of perceived barriers, the number of perceived benefits was a significant predictor of legislators' perceived effectiveness of firearm violence prevention legislation for 8 of the 24 potential firearm violence prevention legislative bills.

In response to the lack of a practical method of monitoring the temperature of athletes, Hothead Technologies developed a device (HOT), which continuously monitors an athlete's fluctuations in body temperature. HOT measures forehead temperature inside helmets. The purpose of this study was to compare HOT against rectal temperature (Trec). Male volunteers (n = 29, age = 23.5 ± 4.5 years, weight = 83.8 ± 10.4 kg, height = 180.1 ± 5.8 cm, body fat = 12.3 ± 4.5%) exercised on a treadmill at an intensity of 60-75% heart rate reserve (HRR) (wet bulb globe temperature [WBGT] = 28.7° C) until Trec reached 38.7° C. The correlation between Trec and HOT was 0.801 (R = 0.64, standard error of the estimate (SEE) = 0.25, p = 0.00). One reason for this relatively high correlation is the microclimate that HOT is monitoring. HOT is not affected by the external climate greatly because of its location in the helmet. Therefore, factors such as evaporation do not alter HOT temperature to a great degree. HOT was compared with Trec in a controlled setting, and the exercise used in this study was moderate aerobic exercise, very unlike that used in football. In a controlled laboratory setting, the relationship between HOT and Trec showed favorable correlations. However, in applied settings, helmets are repeatedly removed and replaced forcing HOT to equilibrate to forehead temperature every time the helmet is replaced. Therefore, future studies are needed to mimic how HOT will be used in field situations.

This study assessed to what extent an enforcement campaign influenced seat-belt and helmet wearing on a Pakistani highway. The study setting was the Karachi-Hala highway where a traffic enforcement campaign was conducted from Dec 2009 to Feb 2010. Seat-belt and helmet wearing were observed in Nov 2009 and Apr 2010 at Karachi toll plaza. Differences in wearing rates as a function of occupants’ age, sex, and vehicle type were compared between the two periods. On average, 9 119 (Standard deviation=1 896) traffic citations were issued per month from Aug 2009 to Feb 2010; 4.2% of which were for not wearing helmet. A 22.5% increase in citations was observed for Dec 2009 to Feb 2010 periods compared with Aug 2009 to Oct 2009 periods. Nearly six thousand four-wheeled and four hundred two-wheeled motorized vehicle occupants were observed in Nov 2009 and Apr 2010. Overall, two of the five drivers and one of the five front seat occupants wore seat belts. This proportion was significantly higher in drivers and front-seat occupants of cars than those of heavier vehicles. Similarly, one of two motorcyclists used a helmet but this proportion was 5.8% for pillion riders in Nov 2009. The increased enforcement had a limited influence on belt wearing in drivers (+4.0%; 95% Confidence Interval [95%CI]=1.8–6.1) and occupants (+6.2%; 95%CI=4.2–8.2). A higher increase was observed for motorcyclists (+9.8%; 95%CI=2.6–16.8) and pillion riders (+12.8%; 95%CI=5.4, 20.5). These results suggested that serious efforts are required to increase seat-belt and helmet use on Pakistani highways. Improving enforcement resources, increased fines, not allowing such vehicles on roads, and awareness campaigns targeting drivers of heavy vehicles might increase wearing rates in Pakistan.

Material property determination of the lining layers of a versatile helmet

Directory of Open Access Journals (Sweden)

Kottner Radek

2018-01-01

Full Text Available This paper deals with material property identification of a helmet lining consisting of an outer layer of an expanded polystyrene (EPS and inner layer of an open-closed cell foam (OCCF. A combined numerical simulation and experimental testing was used for the material property identification. Compression and drop tests were performed. The ABAQUS finite element commercial code was used for numerical simulations in which the OOCF was modelled as a rate dependent viscoelastic material, while the EPS as a crushable foam. The reaction force time histories coming from the numerical simulation and the experiment have been used as a criterion for material parameter determination. After the identification of the material properties, numerical drop-tests were used to study the behaviour of a plate and a conical composite OOCF and EPS liners to decide which of them suits more for the helmet.

Impact response of US Army and National Football League helmet pad systems

Energy Technology Data Exchange (ETDEWEB)

Moss, W C; King, M J

2011-02-18

Lawrence Livermore National Laboratory [LLNL] was tasked to compare the impact response of NFL helmet pad systems and U.S. Army pad systems compatible with an Advanced Combat Helmet [ACH] at impact velocities up to 20 ft/s. This was a one-year study funded by the U.S. Army and JIEDDO. The Army/JIEDDO point of contact is COL R. Todd Dombroski, DO, JIEDDO Surgeon. LLNL was chosen by committee to perform the research based on prior published computational studies of the mechanical response of helmets and skulls to blast. Our collaborators include the U.S. Army Aeromedical Research Laboratory [USAARL] (a DoD laboratory responsible for impact testing helmets), Team Wendy and Oregon Aero (current and former ACH pad manufacturers), Riddell and Xenith (NFL pad manufacturers), and d3o (general purpose sports pad manufacturer). The manufacturer-supplied pad systems that were studied are shown in the figure below. The first two are the Army systems, which are bilayer foam pads with both hard and soft foam and a water-resistant airtight wrapper (Team Wendy) or a water-resistant airtight coating (Oregon Aero). The next two are NFL pad systems. The Xenith system consists of a thin foam pad and a hollow air-filled cylinder that elastically buckles under load. The Riddell system is a bilayer foam pad that is encased in an inflatable airbag with relief channels to neighboring pads in the helmet. The inflatable airbag is for comfort and provides no enhancement to impact mitigation. The d3o system consists of a rate-sensitive homogeneous dense foam. LLNL performed experiments to characterize the material properties of the individual foam materials and the response of the complete pad systems, to obtain parameters needed for the simulations. LLNL also performed X-ray CT scans of an ACH helmet shell that were used to construct a geometrically accurate computational model of the helmet. Two complementary sets of simulations were performed. The first set of simulations reproduced the

Though the 4 mm Gamma Knife helmet is used routinely, there is disagreement in the Gamma Knife users community on the value of the 4 mm helmet relative output factor. A range of relative output factors is used, and this variation may impair observations of dose response and optimization of prescribed dose. To study this variation, measurements were performed using the following radiation detectors: silicon diode, diamond detector, radiographic film, radiochromic film, and TLD cubes. To facilitate positioning of the silicon diode and diamond detector, a three-dimensional translation micrometer was used to iteratively determine the position of maximum detector response. Positioning of the films and TLDs was accomplished by manufacturing custom holders for each technique. Results from all five measurement techniques indicate that the 4 mm helmet relative output factor is 0.868±0.014. Within the experimental uncertainties, this value is in good agreement with results obtained by other investigators using diverse techniques

2009-01-01

The energy absorbing liner of safety helmets was optimised using finite element modelling. In this present paper, a functionally graded foam (FGF) liner was modelled, while keeping the average liner density the same as in a corresponding reference single uniform density liner model. Use of a functionally graded foam liner would eliminate issues regarding delamination and crack propagation between interfaces of different density layers which could arise in liners with discrete density variations. As in our companion Part I paper [Forero Rueda MA, Cui L, Gilchrist MD. Optimisation of energy absorbing liner for equestrian helmets. Part I: Layered foam liner.

Investigation on the applicability of dust protection helmets in the mining industry. Untersuchungen ueber die Einsatzmoeglichkeiten von Staubschutzhelmen im Bergbau

In case of static ambient air, leakages for volumes of 25 x 1,5 l/min and air supplies >= 120 l/min or 25 x 2,0 l/min and >= 160 l/min do not occur. The increasing flow rate of moving ambient air leads to an increase of leakages. They show their largest extensions in case of lateral flow. In addition, they expand together with increasing physiological load. Therefore, the inherent air supply should not be below 160 l/min. The comparison of the dust protection helmet 'Airstream AH 1' with two respirators revealed the lowest additional physiological load for the dust protection helmet. Applicability tests in situ resulted in the following principal objections: contamination and scratches on the visor leading to visibility restriction of the wearer, bad fit, weight distribution and helmet dimensions, pressure sores and chafes of sealing parts and edges, lamp installation. Air supply and movement were felt as too high in case of low ambient temperatures, and in case of high temperatures and physiological strain it was considered as too low. There were only few objections against fan noise, weight and impediment by cable and battery. Based on the results, a specification including monitoring and maintenance of the helmet was made and additional tests for DIN design 58 645, item 7, were induced. Furthermore, a proposal regarding helmet optimisation was made.

Noninvasive positive pressure ventilation (NPPV) using a helmet is expected to cause inspiratory trigger delay due to the large collapsible and compliant chamber. We compared the work of breathing (WOB) of NPPV using a helmet or a full face-mask with that of invasive ventilation by tracheal intubation. We used a lung model capable of simulating spontaneous breathing (LUNGOO; Air Water Inc., Japan). LUNGOO was set at compliance (C) = 50 mL/cmH2O and resistance (R) = 5 cmH2O/L/s for normal lung simulation, C = 20 mL/cmH2O and R = 5 cmH2O/L/s for restrictive lung, and C = 50 mL/cmH2O and R = 20 cmH2O/L/s for obstructive lung. Muscle pressure was fixed at 25 cmH2O and respiratory rate at 20 bpm. Pressure support ventilation and continuous positive airway pressure were performed with each interface placed on a dummy head made of reinforced plastic that was connected to LUNGOO. We tested the inspiratory WOB difference between the interfaces with various combinations of ventilator settings (positive end-expiratory pressure 5 cmH2O; pressure support 0, 5, and 10 cmH2O). In the normal lung and restrictive lung models, WOB decreased more with the face-mask than the helmet, especially when accompanied by the level of pressure support. In the obstructive lung model, WOB with the helmet decreased compared with the other two interfaces. In the mixed lung model, there were no significant differences in WOB between the three interfaces. NPPV using a helmet is more effective than the other interfaces for WOB in obstructive lung disease.

-The purpose of this study was to investigate the changes in skull shape on sonography after cranial molding helmet therapy in infants with deformational plagiocephaly. -Twenty-six infants who were treated with cranial molding helmet therapy were recruited. Caliper and sonographic measurements were performed. The lateral length of the affected and unaffected sides of the skull and cranial vault asymmetry index were measured with calipers. The occipital angle, defined as the angle between lines projected along the lambdoid sutures of the skull, was calculated by sonography. The occipital angle difference and occipital angle ratio were also measured. All caliper and sonographic measurements were performed in each infant twice before and twice after treatment. -The study group included 12 male and 14 female infants with a mean age ± SD of 6.2 ± 3.5 months. The mean treatment duration was 6.0 ± 2.5 months. The difference in lateral length before and after helmet therapy was significantly greater on the affected skull than the unaffected skull (16.7 ± 12.7 versus 9.0 ± 13.4 mm; P skull than the unaffected skull (-5.7° ± 7.3° versus 4.2° ± 7.9°; P < .01). The cranial vault asymmetry index and occipital angle ratio were significantly reduced after helmet therapy (cranial vault asymmetry index, 9.3% ± 2.3% versus 3.5% ± 3.0%; occipital angle ratio, 1.07 ± 0.05 versus 1.01 ± 0.01; P < .05). -These results suggest that occipital angle measurements using sonography, combined with cephalometry, could provide a better understanding of the therapeutic effects of cranial molding helmet therapy in infants with deformational plagiocephaly. © 2016 by the American Institute of Ultrasound in Medicine.

Attendance at NHS mandatory training sessions.

Brand, Darren

2015-02-17

To identify factors that affect NHS healthcare professionals' attendance at mandatory training sessions. A quantitative approach was used, with a questionnaire sent to 400 randomly selected participants. A total of 122 responses were received, providing a mix of qualitative and quantitative data. Quantitative data were analysed using statistical methods. Open-ended responses were reviewed using thematic analysis. Clinical staff value mandatory training sessions highly. They are aware of the requirement to keep practice up-to-date and ensure patient safety remains a priority. However, changes to the delivery format of mandatory training sessions are required to enable staff to participate more easily, as staff are often unable to attend. The delivery of mandatory training should move from classroom-based sessions into the clinical area to maximise participation. Delivery should be assisted by local 'experts' who are able to customise course content to meet local requirements and the requirements of different staff groups. Improved arrangements to provide staff cover, for those attending training, would enable more staff to attend training sessions.

This study examined the effects of videogame distraction and a virtual reality (VR) type head-mounted display helmet for children undergoing cold pressor pain. Fifty children between the ages of 6 and 10 years underwent a baseline cold pressor trial followed by two cold pressor trials in which interactive videogame distraction was delivered via a VR helmet or without a VR helmet in counterbalanced order. As expected, children demonstrated significant improvements in pain threshold and pain tolerance during both distraction conditions. However, the two distraction conditions did not differ in effectiveness. Using the VR helmet did not result in improved pain tolerance over and above the effects of interactive videogame distraction without VR technology. Clinical implications and possible developmental differences in elementary school-aged children's ability to use VR technology are discussed.

One football season of sub-concussive head blows has been shown to be associated with subclinical white matter (WM) changes on diffusion tensor imaging (DTI). Prior research analyses of helmet-based impact metrics using mean and peak linear and rotational acceleration showed relatively weak correlations to these WM changes; however, these analyses failed to account for the emerging concept that neuronal vulnerability to successive hits is inversely related to the time between hits (TBH). To develop a novel method for quantifying the cumulative effects of sub-concussive head blows during a single season of collegiate football by weighting helmet-based impact measures for time between helmet impacts. We further aim to compare correlations to changes in DTI after one season of collegiate football using weighted cumulative helmet-based impact measures to correlations using non-weighted cumulative helmet-based impact measures and non-cumulative measures. We performed a secondary analysis of DTI and helmet impact data collected on ten Division III collegiate football players during the 2011 season. All subjects underwent diffusion MR imaging before the start of the football season and within 1 week of the end of the football season. Helmet impacts were recorded at each practice and game using helmet-mounted accelerometers, which computed five helmet-based impact measures for each hit: linear acceleration (LA), rotational acceleration (RA), Gadd Severity Index (GSI), Head Injury Criterion (HIC 15 ), and Head Impact Technology severity profile (HITsp). All helmet-based impact measures were analyzed using five methods of summary: peak and mean (non-cumulative measures), season sum-totals (cumulative unweighted measures), and season sum-totals weighted for time between hits (TBH), the interval of time from hit to post-season DTI assessment (TUA), and both TBH and TUA combined. Summarized helmet-based impact measures were correlated to statistically significant changes in

The aim of this study was to determine the socioeconomic inequalities in nonuse of seatbelts in cars and helmets on motorcycles in Kurdistan Province, west of Iran, 2009. The data used in this study was collected from the data gathered in non-communicable disease surveillance system (NCDSS) in 2009 in Kurdistan. A total of 1000 people were included in this study. The outcome variable of this study was the nonuse of seatbelts and helmets. The socio-economic status (SES) was calculated based on participants' residential area and assets using Principal Component Analysis (PCA) method. The concentration index, concentration curve, and comparison of Odds Ratio (OR) in different SES groups were used to measure the socioeconomic inequalities using logistic regression. In order to determine the contribution of determinants of inequality, decomposition analysis was used. The prevalence of nonuse of seatbelts in cars and helmets on motorcycles were 47.5%, 95%CI [44%, 55%], respectively. The Concentration index was -0.097, CI [-0.148, -0.046]. The OR of nonuse of seatbelts in cars and helmets on motorcycles in the richest group compared with the poorest group was 0.39, 95%CI [0.23, 0.68]. The results of the decomposition analysis showed that 34% of inequalities were due to SES, 47% were due to residential area, and 12% were due to unknown factors. There is a reverse association between SES and nonuse of seatbelts in cars and helmets on motorcycles. This issue must be considered while planning to reduce traffic accidents injuries.

High sensitivity and high spatial resolution dedicated brain PET scanners are in high demand for early diagnosis of neurodegenerative diseases and studies of brain functions. To meet the demand, we have proposed the helmet-chin PET geometry which has a helmet detector and a chin detector. Our first prototype scanner used 54 4-layer depth-of-interaction (DOI) detectors. The helmet detector of the scanner had three detector rings with different radii arranged on a surface of a hemisphere (with a radius of 126.5 mm) and a top cover detector. Therefore, in this study, for our next development, we propose a spherical arrangement, in which the central axis of each detector points toward the center of the hemisphere, and we optimize the size of the detector crystal block to be arranged on the helmet detector. We simulate the spherical arrangement with the optimized crystal block size and compare its imaging performance with the multi-ring arrangement, which has a similar detector arrangement to that of our first prototype. We conduct Monte Carlo simulation to model the scanners having the 4-layer DOI detectors which consist of LYSO crystals. A dead space of 2 mm is assumed on each side of the crystal blocks such as for wrapping. The size of the crystal block is varied from 4×4 mm{sup 2} to 54×54 mm{sup 2} while fixing the thickness of the crystal block to 20 mm. We find that the crystal block sized at 42×42 mm{sup 2} has the highest sensitivity for a hemispherical phantom. The comparison of the two arrangements with the optimized crystal blocks show that, for the same number of crystal blocks, the spherical arrangement has 17% higher sensitivity for the hemispherical phantom than the multi-ring arrangement. We conclude that the helmet-chin PET with the spherical arrangement constructed from the crystal block sized at 42×42×20 mm{sup 3} has better imaging performance especially at the upper part of the brain compared to the multi-ring arrangement while keeping similar

Heavy metals in toys and low-cost jewelry: critical review of U.S. and Canadian legislations and recommendations for testing.

Science.gov (United States)

Guney, Mert; Zagury, Gerald J

2012-04-17

High metal contamination in toys and low-cost jewelry is a widespread problem, and metals can become bioavailable, especially via oral pathway due to common child-specific behaviors of mouthing and pica. In this review, the U.S., Canadian, and European Union (EU) legislations on metals in toys and jewelry are evaluated. A literature review on content, bioavailability, children's exposure, and testing of metals in toys and low-cost jewelry is provided. A list of priority metals is presented, and research needs and legislative recommendations are addressed. While the U.S. and Canadian legislations put emphasis on lead exposure prevention, other toxic elements like arsenic and cadmium in toy materials are not regulated except in paint and coatings. The EU legislation is more comprehensive in terms of contaminants and scientific approach. Current toy testing procedures do not fully consider metal bioavailability. In vitro bioaccessibility tests developed and validated for toys and corresponding metal bioaccessibility data in different toy matrices are lacking. The U.S. and Canadian legislations should put more emphasis on metal bioavailability and on other metals in addition to lead. A two-step management approach with mandatory testing of toys for total metal concentrations followed by voluntary bioaccessibility testing could be implemented.

A parametric study was conducted to delineate the efficacy of personal protective equipment (PPE), such as ballistic faceshields and advanced combat helmets, in the case of a blast. The propagations of blast waves and their interactions with an unprotected head, a helmeted one, and a fully protected finite element head model (FEHM) were modeled. The biomechanical parameters of the brain were recorded when the FEHM was exposed to shockwaves from the front, back, top, and bottom. The directional dependent tissue response of the brain and the variable efficiency of PPE with respect to the blast orientation were two major results of this study.

To apply Prochaska's Transtheoretical model of behavior change to bicycle helmet use among middle school, high school, and college students. A battery of questionnaires was administered to cyclists in the seventh and ninth grades and to college students in Phoenix, Arizona (N=797). The battery included: (1) a question to determine respondent's stage of behavior change in Prochaska's Transtheoretical model; (2) items assessing the perceived pros and cons of helmet use; (3) a bicycle safety knowledge test; and (4) demographic information. Forty-three percent of the students were in "Precontemplation," 17% were in either "Contemplation" or "Preparation," 16% were in either "Action" or "Maintenance," and 24% were in the "Relapse" stage of change. Grade, Sex, Knowledge, Pros, and Cons, and the Grade by sex and the Grade by knowledge interactions were significant predictors of helmet use stages. Compared with students in Precontemplation, students in the Contemplation stage were disproportionately younger and had higher Pro scores, lower Con scores, and more knowledge (except in the ninth grade). The Transtheoretical model of behavior change is a viable theoretical framework for designing interventions aimed at increasing bicycle helmet use in children and adolescents.

Cattarin, M; Bellè, M; Bergamini, M; Gallo, L

2013-09-01

The burden of infectious diseases preventable by vaccination decreased considerably over last decades in all countries provided with effective immunization schedules. Implementation of these programs with new vaccines has started discussion on duality between mandatory and recommended vaccinations. Regional autonomy has allowed the Veneto Region, with introduction of Law 7/2007, to experience suspension of all mandatory childhood vaccinations, replaced by an active and free offer of all vaccines recognized as safe and effective. Coverage's trends and acceptance of invitation are carefully monitored to avoid loss of compliance and reduction of immunized children. The evaluation, performed on population of Rovigo ULSS18 for 2002-2008 birth cohorts (2008 is the first concerned by the change), revealed no fall for previously mandatory vaccinations, but rather a slight increase. Percentage of non-vaccinated children was negligible. The leading cause of non-vaccination to polio was inability to deliver the letter of invitation due to wrong address. An informed dissent was expressed only by a minority (0.9% in 2008 birth cohort). Compliance to immunization offer was elevated both for previously compulsory and recommended vaccinations. Experience of Rovigo ULSS 18 showed that, in a context of already high levels of coverage for recommended vaccinations with optimal organization of immunization services, coverage rates for ex-mandatory vaccines remain unchanged. Further research and reports are required to carefully assess the effect on coverage rates in next birth cohorts, but available data are encouraging. Similar legislative measures can be successfully adopted by other Regions with starting conditions comparable to Veneto Region.

Impact of Helmet Use on Injury and Financial Burden of Motorcycle and Moped Crashes in Hawai‘i: Analysis of a Linked Statewide Database

Science.gov (United States)

Castel, Nikki A; Wong, Linda L; Steinemann, Susan

2016-01-01

Helmet use reduces injury severity, disability, hospital length of stay, and hospital charges in motorcycle riders. The public absorbs billions of dollars annually in hospital charges for unhelmeted, uninsured motorcycle riders. We sought to quantify, on a statewide level, the healthcare burden of unhelmeted motorcycle and moped riders. We examined 1,965 emergency medical service (EMS) reports from motorcycle and moped crashes in Hawai‘i between 2007–2009. EMS records were linked to hospital medical records to assess associations between vehicle type, helmet use, medical charges, diagnoses, and final disposition. Unhelmeted riders of either type of vehicle suffered more head injuries, especially skull fractures (adjusted odds ratio (OR) of 4.48, P motorcycle and moped riders, with a significant (P = .006) difference between helmeted ($27,176) and unhelmeted ($40,217) motorcycle riders. Unhelmeted riders were twice as likely to self-pay (19.3%, versus 9.8% of helmeted riders), and more likely to have Medicaid or a similar income-qualifying insurance plan (13.5% versus 5.0%, respectively). Protective associations with helmet use are stronger among motorcyclists than moped riders, suggesting the protective effect is augmented in higher speed crashes. The public financial burden is higher from unhelmeted riders who sustain more severe injuries and are less likely to be insured. PMID:27980882

Cognitive considerations for helmet-mounted display design

Science.gov (United States)

Francis, Gregory; Rash, Clarence E.

2010-04-01

Helmet-mounted displays (HMDs) are designed as a tool to increase performance. To achieve this, there must be an accurate transfer of information from the HMD to the user. Ideally, an HMD would be designed to accommodate the abilities and limitations of users' cognitive processes. It is not enough for the information (whether visual, auditory, or tactual) to be displayed; the information must be perceived, attended, remembered, and organized in a way that guides appropriate decision-making, judgment, and action. Following a general overview, specific subtopics of cognition, including perception, attention, memory, knowledge, decision-making, and problem solving are explored within the context of HMDs.

To test whether a head-mounted display helmet enhances the effectiveness of videogame distraction for children experiencing cold pressor pain. Forty-one children, aged 6-14 years, underwent one or two baseline cold pressor trials followed by two distraction trials in which they played the same videogame with and without the helmet in counterbalanced order. Pain threshold (elapsed time until the child reported pain) and pain tolerance (total time the child kept the hand submerged in the cold water) were measured for each cold pressor trial. Both distraction conditions resulted in improved pain tolerance relative to baseline. Older children appeared to experience additional benefits from using the helmet, whereas younger children benefited equally from both conditions. The findings suggest that virtual reality technology can enhance the effects of distraction for some children. Research is needed to identify the characteristics of children for whom this technology is best suited.

Full-color wide field-of-view holographic helmet-mounted display for pilot/vehicle interface development and human factors studies

Burley, James R., II; LaRussa, Joseph A.

1990-10-01

A Helmet-Mounted Display (HMD) which utilizes highly efficient trichromatic holographic elements has been designed to support pilot vechicle interface development and human factors studies at the NASA-Langley Research Center. While the optics are fully color corrected, the miniature CRT's are monochromatic. This design provides an upgrade path to full-color when miniature display technology matures to color. The optical design conforms to the helmet shape and provides a 50 degree field-of-view (FOV) to each eye. Built-in adjustments allow each ocular to be independently moved so that the overall horizontal FOV may be varied from 50 degrees to 100 degrees with a corresponding change in the stereo overlap region. The helmet design and interpupillary adjustment allow for the 5th through 95th percentile male and female wearer. Total head-borne weight is approximately 4.2 pounds. The high-resolution monochromatic CRTs are driven by a set of multisync electronics with a maximum video bandwidth of 88 Mhz and supports bith raster and stroke modes. The electronics are designed to be compatiable with the Silicon Graphics IRIS 4D graphics workstations and the ADAGE 340 stroke graphics computer. A Polhemus magnetic tracking device is used to determine the helmet line-of-sight. The helmet will be used to develop innovative new display concepts for the F- 1 8 High-Alpha Research Vehicle (HARV) which make use of the unique display properties of the HMD. Pictorial displays, which convey the appropriate information intuitively, are envisioned. Human factors studies are also planned to evaluate the utility of stereopsis and determine the FOV requirements for different tasks. Concepts proven in the simulator will be carried to flight test in 1993 with a lighter weight, "hardened" version of this HMD design.

Neutron and X-ray characterisation of the metallurgical properties of a 7th century BC Corinthian-type bronze helmet

2005-09-01

Neutron and synchrotron X-ray diffraction, X-ray fluorescence and FTIR were used to examine a Corinthian-type bronze helmet which is now on display at The Manchester Museum, UK. This type of helmet was manufactured out of a single piece of bronze, probably on a rod-anvil, and like all body-armour it was made to measure. Neutron diffraction sampling of the bronze volume in different areas was used to study the composition, microstructure and crystallographic texture of the alloy in order to draw conclusions about the manufacturing processes. The neutron data revealed the presence of microstrains and non-random distributions of bronze grains hinting at annealing-hammering working cycles in order to harden and shape the alloy. X-ray fluorescence showed that the main body of the helmet is a copper-tin alloy, while the noseguard contains zinc in high abundance. This key compositional difference confirms that the noseguard is not the original but is a modern substitute fabricated for restoration purposes. SR XRD and FTIR from several spots on the head and noseguard identified several surface corrosion products and showed a variation of the Cu-Sn or Cu-Zn percentage compositions, and of the mineral phases. Small samples of corrosion flakes extracted from the outside and inside of the helmet were used to obtain powder XRD patterns.

Sivasankar, S; Karmegam, K; Bahri, M T Shamsul; Naeini, H Sadeghi; Kulanthayan, S

2014-01-01

Motorcycles are a common mode of transport for most Malaysians. Underbone motorcycles are one of the most common types of motorcycle used in Malaysia due to their affordable price and ease of use, especially in heavy traffic in the major cities. In Malaysia, it is common to see a young or child pillion rider clinging on to an adult at the front of the motorcycle. One of the main issues facing young pillion riders is that their safety is often not taken into account when they are riding on a motorcycle. This article reviews the legally available systems in child safety for underbone motorcycles in Malaysia while putting forth the need for a safety system for child pillion riders. Various databases were searched for underbone motorcycle safety systems, related legislation, motorcycle accident data, and types of injuries and these were reviewed to put forth the need for a new safety system. In motorcycle-related accidents, children usually sustain lower limb injuries, which could temporarily or permanently inhibit the child's movements. Accident statistics in Malaysia, especially those involving motorcycles, reflect a pressing need for a reduction in the number of accidents. In Malaysia, the legislation does not go beyond the mandatory use of safety helmets for young pillion users. There is a pressing need for another safety system or mechanism(s) for young pillion riders of underbone motorcycles. Enforcement of laws to enforce the usage of passive safety systems such as helmets and protective gear is difficult in underdeveloped and developing countries. The intervention of new technology is inevitable. Therefore, this article highlights the need for a new safety backrest system for child pillion riders to ensure their safety.

Mandatory Continuing Professional Education (CPE) for the renewal of pharmacists' practising certificate was implemented in Singapore in 2008 OBJECTIVE: To study pharmacists' perceptions and attitudes about the impact of mandatory CPE in Singapore. Singapore. Internet-based questionnaire survey, conducted between May and June 2011. Pharmacists' perceptions and attitudes toward mandatory CPE and the perceived difficulty in fulfilling the CPE requirements. The overall survey response rate was 52 % (840/1,609). Of the respondents, 32 % were non-practising, 49 % were practising in patient care areas, and 19 % were practising in non-patient care areas. More than half the pharmacists agreed that mandatory CPE (1) enhanced or increased their knowledge base and skills (70 %; 95 % CI 67-73 %), (2) motivated them to continually learn (64 %; 95 % CI, 60-67 %), and (3) motivated them to reflect on their professional practice or work (58 %; 95 % CI, 54-61 %). Mandatory CPE was not perceived to enhance or increase employability. Non-practising pharmacists appeared to have the greatest difficulty meeting the CPE requirements. In general, pharmacists value mandatory CPE more for positive professional reasons than for employability reasons. The survey results may serve as useful baseline data for future studies of pharmacists' perceptions and attitudes toward CPE in Singapore.

The new Italian IVF legislation.

Science.gov (United States)

Benagiano, Giuseppe; Gianaroli, Luca

2004-08-01

Last February, the Italian Parliament gave final approval to a new Law regulating assisted reproduction technology. The new legislation fell short of the expectations of infertile couples and of all specialists in the field. There are three problems with the new Italian law; they involve social issues, human rights and the application of technology. The present paper focuses on the fact that the new rules infringe upon basic human rights and the proper application of IVF technology, because they mandate procedures that are against the best interest of the woman seeking pregnancy. The main point of controversy is the combination of a mandatory limit of three embryos for transfer, and an obligation to reimplant all produced embryos; cryopreservation of excess embryos is prohibited. Obviously, this decreases the chances of most women to achieve pregnancy, while at the same time it increases the number and complexity of procedures they need to undergo and may expose some to an unacceptable increase in the risk of multiple pregnancy. The new law is inspired by the desire to protect every newly produced embryo; this is a commendable aim, although it is in total opposition to a law passed over 25 years ago that liberalized voluntary termination of first trimester pregnancies. This means that today Italy has a law that protects every early, pre-implantation embryo, and another that allows the 'suppression' of every post-implantation one. From a technical point of view, given the low level of human fecundity, the only way to prevent the 'loss' of even one preimplantation embryo is to simply ban IVF altogether, an option that Italian legislators obviously did not have the courage to opt for. The tragedy is that Italian infertile couples are now confronted with new rules that not only severely limit the ability of physicians to correctly apply IVF technology, but are so confused that, depending on the interpretation, anyone may try to nullify the main ideological premise upon

Hawaii state legislator views on e-cigarettes and likelihood of legislative action.

2015-01-01

To examine perspectives on e-cigarette use and regulations in Hawaii through key informant interviews with state legislators. E-cigarette use is rapidly increasing, with sales in 2013 topping $1 billion in the United States, but e-cigarettes are still a largely unregulated industry. Although e-cigarettes are thought by most to be a healthier alternative to traditional cigarettes, long-term health effects are not yet known. Semistructured key informant interviews were conducted with Hawaii state legislators (n = 15). We found a lack of consensus among legislators, which suggests that substantial legislative action is unlikely in the upcoming session. However, most legislators believe that some type of incremental legislation will pass, such as enactment of a small tax, limitations on advertising to protect adolescents, or regulations concerning where people can use e-cigarettes. Legislators eagerly await further research to clarify the overall benefits and harms of e-cigarettes at both the individual and population levels.

Successful Removal of Football Helmet Face-Mask Clips After 1 Season of Use

Scibek, Jason S.; Gatti, Joseph M.; McKenzie, Jennifer I.

2012-01-01

Context Whereas many researchers have assessed the ability to remove loop straps in traditional face-mask attachment systems after at least 1 season of use, research in which the effectiveness of the Riddell Quick Release (QR) Face Guard Attachment System clip after 1 season has been assessed is limited. Objective To examine the success rate of removing the QR clips after 1 season of use at the Football Championship Subdivision level. We hypothesized that 1 season of use would negatively affect the removal rate of the QR clip but repeated clip-removal trials would improve the removal rate. Design Retrospective, quasi-experimental design. Setting Controlled laboratory study. Patients or Other Participants Sixty-three football helmets from a National Collegiate Athletic Association Division I university located in western Pennsylvania used during the 2008 season were tested. Intervention(s) Three certified athletic trainers (2 men, 1 woman; age = 31.3 ± 3.06 years, time certified = 9.42 ± 2.65 years) attempted to remove the QR clips from each helmet with the tool provided by the manufacturer. Helmets then were reassembled to allow each athletic trainer to attempt clip removal. Main Outcome Measure(s) The dependent variables were total left clips removed (TCR-L), total right clips removed (TCR-R), and total clips removed (TCR). Success rate of clip removal (SRCR) also was assessed. Results Percentages for TCR-L, TCR-R, and TCR were 100% (189 of 189), 96.30% (182 of 189), and 98.15% (371 of 378), respectively. A paired-samples t test revealed a difference between TCR-R and TCR-L (t188 = −2.689, P = .008, μd = 0.037, 95% confidence interval [CI] = −0.064, −0.010). The percentage for SRCR was 96.30% (n = 182), whereas SRCR percentages for trials 1, 2, and 3 were 95.24% (n = 60), 98.41% (n = 62), and 95.24% (n = 60), respectively, and did not represent a difference (F2,186 = 0.588, P = .56, 95% CI = 0.94, 0.99).

Swartz, Erik E.; Belmore, Keith; Decoster, Laura C.; Armstrong, Charles W.

2010-01-01

Abstract Context: Football helmet face-mask attachment design changes might affect the effectiveness of face-mask removal. Objective: To compare the efficiency of face-mask removal between newly designed and traditional football helmets. Design: Controlled laboratory study. Setting: Applied biomechanics laboratory. Participants: Twenty-five certified athletic trainers. Intervention(s): The independent variable was face-mask attachment system on 5 levels: (1) Revolution IQ with Quick Release (QR), (2) Revolution IQ with Quick Release hardware altered (QRAlt), (3) traditional (Trad), (4) traditional with hardware altered (TradAlt), and (5) ION 4D (ION). Participants removed face masks using a cordless screwdriver with a back-up cutting tool or only the cutting tool for the ION. Investigators altered face-mask hardware to unexpectedly challenge participants during removal for traditional and Revolution IQ helmets. Participants completed each condition twice in random order and were blinded to hardware alteration. Main Outcome Measure(s): Removal success, removal time, helmet motion, and rating of perceived exertion (RPE). Time and 3-dimensional helmet motion were recorded. If the face mask remained attached at 3 minutes, the trial was categorized as unsuccessful. Participants rated each trial for level of difficulty (RPE). We used repeated-measures analyses of variance (α  =  .05) with follow-up comparisons to test for differences. Results: Removal success was 100% (48 of 48) for QR, Trad, and ION; 97.9% (47 of 48) for TradAlt; and 72.9% (35 of 48) for QRAlt. Differences in time for face-mask removal were detected (F4,20  =  48.87, P  =  .001), with times ranging from 33.96 ± 14.14 seconds for QR to 99.22 ± 20.53 seconds for QRAlt. Differences were found in range of motion during face-mask removal (F4,20  =  16.25, P  =  .001), with range of motion from 10.10° ± 3.07° for QR to 16.91° ± 5.36° for TradAlt. Differences also were detected

Szymon Okoń

2012-06-01

Full Text Available The following paper aims to assess investor reaction to mandatory offers on the Warsaw Stock Exchange, which is important because knowledge about these reactions can be used to make better investment decisions. This paper highlights the importance of procedure in making a mandatory offer and its grounds in the Polish legal system. Additionally, it presents empirical research on the reactions of investors to mandatory offers on the Warsaw Stock Exchange. It has been provided that mandatory offers have a significant impact on the price of a company’s shares listed on the Warsaw Stock Exchange. Knowledge about the reactions of investors to a mandatory offer may be used when selecting securities for an investment portfolio. The findings may provide guidance in deciding whether to begin or end investment in the company, both for individual and institutional investors. The event study methodology approach used in the paper is regarded as valuable and can be the basis for further research in other areas of the capital market research, especially in the context of information efficiency.

2009-05-01

Helmet-Mounted Display (HMD) technologies have been developing for over 3 decades and have been studied for multiple applications ranging from military aircraft, to virtual reality, augmented reality, entertainment and a host of other ideas. It would not be unreasonable to assume that after this much time they would be employed in our daily lives as ubiquitously as the common desktop monitor. However, this is simply not the case. How can this be when they can be used in so many ways for so many tasks? Throughout this work we will look at some of the reasons why as well of some of the ways they can be used.

2006-05-01

The Advanced Helmet Mounted Display (AHMD), augmented reality visual system first presented at last year's Cockpit and Future Displays for Defense and Security conference, has now been evaluated in a number of military simulator applications and by L-3 Link Simulation and Training. This paper presents the preliminary results of these evaluations and describes current and future simulator and training applications for HMD technology. The AHMD blends computer-generated data (symbology, synthetic imagery, enhanced imagery) with the actual and simulated visible environment. The AHMD is designed specifically for highly mobile deployable, minimum resource demanding reconfigurable virtual training systems to satisfy the military's in-theater warrior readiness objective. A description of the innovative AHMD system and future enhancements will be discussed.

Digital Image Processing Overview For Helmet Mounted Displays

Parise, Michael J.

1989-09-01

Digital image processing provides a means to manipulate an image and presents a user with a variety of display formats that are not available in the analog image processing environment. When performed in real time and presented on a Helmet Mounted Display, system capability and flexibility are greatly enhanced. The information content of a display can be increased by the addition of real time insets and static windows from secondary sensor sources, near real time 3-D imaging from a single sensor can be achieved, graphical information can be added, and enhancement techniques can be employed. Such increased functionality is generating a considerable amount of interest in the military and commercial markets. This paper discusses some of these image processing techniques and their applications.

How effective is mandatory building energy disclosure program in Australia?

Science.gov (United States)

Kim, S.; Lim, B. T. H.

2018-04-01

Mandatory green building regulations are often considered as the most effective tool to promote better energy efficiency and environmental protection. Nevertheless, its effectiveness compared to the voluntary counterpart has not been fully explored yet. In addressing this gap, this study aims to examine the environmental performance of green building stocks affected by the Australian mandatory building energy disclosure program. To this, this study analysed energy savings and carbon reduction efficiencies using the normalisation approach. The result shows that mandatory energy disclosure program did contribute to the reduction in energy usage and carbon emissions from the affected building stocks. More specifically, affected green building stocks showed a good efficiency especially in carbon reductions. The research results inform policymakers the possible improvement required for the mandatory disclosure program to increase the effectiveness towards dealing with the contemporary environmental issues aroused from the building sector, especially in energy savings perspective.

Full Text Available A number of reality for laws as a production of Parliament and President was canceled by the Constitutional Court, occur as a result of the legislation matter that plural reflects the injustice and legal uncertainty. The high number of judicial review becomes signal less accommodation of citizen interests and rights in a legislation product. The absence of arrangement harmony made by Parliament gives impact on plural legislation sued. This paper attempts to describe some debate antinomy that characterizes the existence of legislation in Indonesia. The analysis showed, antinomy-conflict-norm in the legislation is one thing that is difficult to avoid, especially given the poor-legislative process in the parliament today. In each establishment of legislation, synchronization and norms harmonization is not a major pressing point, but defeated by transnational politics inter-faction in the parliament that actually looked more dominant. But when these norms conflict constituted a rule of law which are simultaneous, dynamic, and meet legal ideals, would not be a problem. As long as not to cause harm to the fulfillment of constitutional rights of citizens.

Lee, Joo-Young; Yamamoto, Yota; Oe, Riichi; Son, Su-Young; Wakabayashi, Hitoshi; Tochihara, Yutaka

2014-01-01

The purpose of this study was to investigate the physiological and subjective responses of the European, Japanese (JPN) and US firefighters' helmet, gloves and boots for international standardisation. Three experimental conditions were evaluated (clothing mass: 9.4, 8.2 and 10.1 kg for the three conditions, respectively) at the air temperature of 32°C and 60% relative humidity. The results showed that there was no significant difference among the three conditions in oxygen consumption, heart rate, total sweat rate, rectal temperature and mean skin temperature, whereas peripheral temperatures and subjective perceptions were lower in the JPN condition than in the other conditions (P < 0.05). These results indicate that a 0.5-kg reduction in helmet mass and a 1.1-kg reduction in boot mass during exercise resulted in a significant decrease in head and leg temperatures and subjective perceptions, while a 1.9-kg reduction in total clothing mass had insignificant influences on the metabolic burden and overall body temperature.

This paper presents the author's view that the coal industry should develop a strategy to respond to the global warming issue. A few weeks ago a speaker stated that the global warming issue placed coal at the crossroads. He stated that global warming legislation, could reduce the consumption of coal by approximately twenty-five percent, without global warming legislation coal would continue to grow at a approximately three percent per year. It is believed there is a path to be traveled between the two options, legislation or no legislation, that can result in coal obtaining the position as the primary fuel source for electrical generating throughout the world. This is a path the coal industry can define and should follow

Viano, David C; Withnall, Chris; Wonnacott, Michael

2012-01-01

An instrumented Hybrid III head was placed in a Schutt ION 4D football helmet and dropped on different turfs to study field types and temperature on head responses. The head was dropped 0.91 and 1.83 m giving impacts of 4.2 and 6.0 m/s on nine different football fields (natural, Astroplay, Fieldturf, or Gameday turfs) at turf temperatures of -2.7 to 23.9 °C. Six repeat tests were conducted for each surface at 0.3 m (1') intervals. The Hybrid III was instrumented with triaxial accelerometers to determine head responses for the different playing surfaces. For the 0.91-m drops, peak head acceleration varied from 63.3 to 117.1 g and HIC(15) from 195 to 478 with the different playing surfaces. The lowest response was with Astroplay, followed by the engineered natural turf. Gameday and Fieldturf involved higher responses. The differences between surfaces decreased in the 1.83 m tests. The cold weather testing involved higher accelerations, HIC(15) and delta V for each surface. The helmet drop test used in this study provides a simple and convenient means of evaluating the compliance and energy absorption of football playing surfaces. The type and temperature of the playing surface influence head responses.

Is mandatory research ethics reviewing ethical?

Science.gov (United States)

Dyck, Murray; Allen, Gary

2013-08-01

Review boards responsible for vetting the ethical conduct of research have been criticised for their costliness, unreliability and inappropriate standards when evaluating some non-medical research, but the basic value of mandatory ethical review has not been questioned. When the standards that review boards use to evaluate research proposals are applied to review board practices, it is clear that review boards do not respect researchers or each other, lack merit and integrity, are not just and are not beneficent. The few benefits of mandatory ethical review come at a much greater, but mainly hidden, social cost. It is time that responsibility for the ethical conduct of research is clearly transferred to researchers, except possibly in that small proportion of cases where prospective research participants may be so intrinsically vulnerable that their well-being may need to be overseen.

An empirical comparison of voluntary and mandatory building energy performance disclosure outcomes

International Nuclear Information System (INIS)

Gabe, Jeremy

2016-01-01

In 2010, the federal Australian government mandated the disclosure of energy performance ratings in advertisements for sale or lease of large commercial office properties. Prior to 2010, participation in the rating scheme was voluntary. This study first develops a theoretical model of mandatory disclosure policy effectiveness. Then, with a dataset of all ratings since inception of the voluntary regime in 1999, it tests the expectation that initial voluntary adopters have a greater tendency towards environmental stewardship and are more likely to manage and invest in environmental performance improvements, potentially dampening the effectiveness of mandatory disclosure policy. However, multiple statistical models of certification are unable to reject the null hypothesis that there is no difference in energy efficiency outcomes between the mandatory and voluntary adopters at equivalent stages. For urban policymakers, the extrapolation of voluntary adopter performance appears to be a good – perhaps even conservative – estimation of mandatory energy performance disclosure outcomes. - Highlights: •A theoretical model of building energy disclosure policy effectiveness is proposed. •Mandatory disclosure adopters reduce consumption similar to voluntary adopters. •Mandatory building energy disclosure in Australia has been effective. •Early adopters creating a market for energy retrofits is a likely reason for success.

School cardiopulmonary resuscitation (CPR) training has become mandatory in many countries, but whether legislation has translated into implementation of CPR training is largely unknown. We assessed CPR training of students following 8 years of legislative mandates in Denmark. A nationwide cross-sectional survey of Danish school leadership (n=1240) and ninth-grade homeroom teachers (n=1381) was carried out for school year 2013-2014. Qualitative interviews and the Theory of Planned Behavior were used to construct the survey. Logistic regression models were employed to identify factors associated with completed CPR training. Information from 63.1% of eligible schools was collected: 49.3% (n=611) of leadership and 48.2% (n=665) of teachers responded. According to teachers, 28.4% (95% CI 25.0% to 32.0%) and 10.3% (95% CI 8.1% to 12.8%) of eligible classes had completed CPR and automated external defibrillator training, respectively. Among leadership, 60.2% (95% CI 56.2% to 64.1%) reported CPR training had occurred during the 3 years prior to the survey. Factors associated with completed CPR training included believing other schools were conducting training (odds ratio [OR] 9.68 [95% CI 4.65-20.1]), awareness of mandating legislation (OR 4.19 [95% CI 2.65-6.62]), presence of a school CPR training coordinator (OR 3.01 [95% CI 1.84-4.92]), teacher feeling competent to conduct training (OR 2.78 [95% CI 1.74-4.45]), and having easy access to training material (OR 2.08 [95% CI 1.57-2.76]). Despite mandating legislation, school CPR training has not been successfully implemented. Completed CPR training was associated with believing other schools were conducting training, awareness of mandating legislation, presence of a school CPR training coordinator, teachers teacher feeling competent to conduct training, and having easy access to training material. Facilitating these factors may increase rates of school CPR training. © 2017 The Authors. Published on behalf of the

Comparisons of mandatory and discretionary lane changing behavior on freeways

Directory of Open Access Journals (Sweden)

Matthew Vechione

2018-06-01

Full Text Available This research performs comparative analyses on drivers’ behavior during mandatory and discretionary lane changes. We do this by examining the statistical properties of four lane changing decision variables that describe the gaps between the subject vehicle and the surrounding vehicles. Mandatory and discretionary lane changes in NGSIM’s I-80 Freeway and U.S. Highway 101 data collection sites were identified. First, for each variable at the same site, descriptive statistics for the two types of lane changes were compared, and hypothesis tests on the difference between two means were conducted. Then, for each decision variable at the same site, the observed cumulative distributions between the mandatory and discretionary lane changes were compared by means of the Kolmogorov–Smirnov test. This test was repeated for the fitted distributions of the same decision variable at the same site. The results show that, for the three decision variables associated with gaps in the target lane, the means and distributions between the two types of lane changes are not significantly different. The only variable found to have significant differences in means and distributions is the gap between the subject vehicle and the preceding vehicle in the original lane. This may be because this variable is not an important input in mandatory lane change decisions. This finding provides statistical justification for researchers to develop models with different inputs for mandatory and discretionary lane changes in driver assist systems, in autonomous vehicles, and in microscopic traffic simulation tools.

2014-01-01

Medical ethics is a realm where four important subjects of philosophy, medicine, theology and law are covered. Physicians and philosophers cooperation in this area will have great efficiency in the respective ethical rules formation. In addition to respect the autonomy of the patient, physician's obligation is to ensure that the medical intervention has benefit for the patient and the harm is minimal. There is an obvious conflict between duty of confidentiality and duty of mandatory reporting. Professional confidentiality is one of the basic components in building a constant physician-patient relationship which nowadays, beside the novelty, it is the subject of discussion. Legal obligation of confidentiality is not absolute. In physician-patient relationship, keeping patient's secrets and maintaining confidentiality is a legal and ethical duty, and disclosure of such secrets is mainly through specific statutes. Thus, there are a number of situations where breach of confidentiality is permitted in different legal systems. One of the situations where breaching confidentiality is permitted is the medical mandatory reporting to the relevant authority which is in accordance with many countries' legal systems. Some situations are considered in many countries legal systems' such as notification of births and deaths, infectious diseases, child abuse, sport and relevant events, medical errors, drug side effects and dangerous pregnancies. In this paper, we will examine and discuss medical mandatory reporting and its ethical and legal aspects in the judicial and legal system of Iran and few other countries. Finally we will suggest making Medical Mandatory Reporting Law in Iran.

Helmet-mounted displays in long-range-target visual acquisition

Science.gov (United States)

Wilkins, Donald F.

1999-07-01

Aircrews have always sought a tactical advantage within the visual range (WVR) arena -- usually defined as 'see the opponent first.' Even with radar and interrogation foe/friend (IFF) systems, the pilot who visually acquires his opponent first has a significant advantage. The Helmet Mounted Cueing System (HMCS) equipped with a camera offers an opportunity to correct the problems with the previous approaches. By utilizing real-time image enhancement technique and feeding the image to the pilot on the HMD, the target can be visually acquired well beyond the range provided by the unaided eye. This paper will explore the camera and display requirements for such a system and place those requirements within the context of other requirements, such as weight.

Garcia, Robin; Vonderheid, Susan; McFarlin, Barbara; Djonlich, Michelle; Jang, Catherine; Maghirang, Jeffrey

2011-06-01

Methicillin-resistant Staphylococcus aureus (MRSA) rates continue to rise and pose a threat to patient health and limited hospital resources. In 2007, Illinois passed a legislative mandate requiring active surveillance cultures to screen for MRSA in all patients in hospital intensive care units. However, professional guidelines do not support mandated universal surveillance cultures, and funding to cover screening costs was not included. The purpose of the study was to examine the costs (personnel, screening test, and supply) associated with the mandated universal MRSA screening and to examine the infant health-related outcomes and costs associated with implementing MRSA screening in a special care nursery. Personnel-54 observations of staff members in a community-based hospital in a large midwestern city. Infants-445 infants admitted from January 2008 through January 2009. Time and motion (related to screening activities by registered nurses) based on observations of staff during MRSA screenings, and abstraction of health and cost data from the infant log, infant medical records, and financial reports. Costs (laboratory tests, personnel, and supplies) and infant health outcomes. A prospective descriptive study. Mandatory screening leads to increased costs, problems related to false-positives, and unintended consequences (eg, decision whether to treat non-MRSA organisms identified on screening cultures, possibility of legal implications, adverse family psychosocial affects, and questionable validity of the polymerase chain reaction test). The average total costs of laboratory, supply, and personnel were $15,270.12 ($34.31 per infant or $19.58 per screen). A screening test for MRSA with a high positive predictive value, low cost, and quick turnaround (providers require evidence when determining best practices, legislators should require adequate evidence before passing policy.

A libertarian case for mandatory vaccination.

Science.gov (United States)

Brennan, Jason

2018-01-01

This paper argues that mandatory, government-enforced vaccination can be justified even within a libertarian political framework. If so, this implies that the case for mandatory vaccination is very strong indeed as it can be justified even within a framework that, at first glance, loads the philosophical dice against that conclusion. I argue that people who refuse vaccinations violate the 'clean hands principle', a (in this case, enforceable) moral principle that prohibits people from participating in the collective imposition of unjust harm or risk of harm. In a libertarian framework, individuals may be forced to accept certain vaccines not because they have an enforceable duty to serve the common, and not because cost-benefit analysis recommends it, but because anti-vaxxers are wrongfully imposing undue harm upon others.

Helmet-mounted display requirements: just another head-up display (HUD) or a different animal altogether?

Science.gov (United States)

Newman, Richard L.; Haworth, Loran A.

1994-06-01

The helmet-mounted display (HMD) presents flight, navigation, and weapon information in the pilot's line of sight. The HMD was developed to allow the pilot to retain aircraft and weapon information while looking off boresight. The present study reviewed the state-of-the-art in HMDs and identified a number of issues applying to HMDs. Several are identical to head-up display (HUD) issues: symbol standardization, excessive clutter, and the need for integration with other cockpit displays and controls. Other issues are unique to the head-mounted display: symbol stabilization, inadequate definitions, undefined symbol drive laws, helmet considerations, and field-of-view (FOV) vs. resolution tradeoff requirements. Symbol stabilization is critical. In the Apache helicopter, the lack of compensation for pilot head motion creates excessive workload during hovering and nap-of-the-earth (NOE) flight. This high workload translates into excessive training requirements. At the same time, misleading symbology makes interpretation of the height of obstructions impossible. The underlying cause is the absence of design criteria for HMDs. The existing military standard does not reflect the current state of technology. In addition, there are inadequate test and evaluation guidelines. The situation parallels the situation for HUDs several years ago.

Staton, Sally L; Smith, Simon S; Hurst, Cameron; Pattinson, Cassandra L; Thorpe, Karen J

2017-01-01

Policy provision for naps is typical in child care settings, but there is variability in the practices employed. One practice that might modify children's early sleep patterns is the allocation of a mandatory nap time in which all children are required to lie on their beds without alternate activity permitted. There is currently limited evidence of the effects of such practices on children's napping patterns. This study examined the association between duration of mandatory nap times and group-level napping patterns in child care settings. Observations were undertaken in a community sample of 113 preschool rooms with a scheduled nap time (N = 2,114 children). Results showed that 83.5% of child care settings implemented a mandatory nap time (range = 15-145 min) while 14.2% provided alternate activities for children throughout the nap time period. Overall, 31% of children napped during nap times. Compared to rooms with ≤ 30 min of mandatory nap time, rooms with 31-60 min and > 60 min of mandatory nap time had a two-and-a-half and fourfold increase, respectively, in the proportion of children napping. Nap onset latency did not significantly differ across groups. Among preschool children, exposure to longer mandatory nap times in child care may increase incidence of napping.

Designing safer composite helmets to reduce rotational accelerations during oblique impacts.

Science.gov (United States)

Mosleh, Yasmine; Cajka, Martin; Depreitere, Bart; Vander Sloten, Jos; Ivens, Jan

2018-05-01

Oblique impact is the most common accident situation that occupants in traffic accidents or athletes in professional sports experience. During oblique impact, the human head is subjected to a combination of linear and rotational accelerations. Rotational movement is known to be responsible for traumatic brain injuries. In this article, composite foam with a column/matrix composite configuration is proposed for head protection applications to replace single-layer uniform foam, to better attenuate rotational movement of the head during oblique impacts. The ability of composite foam in the mitigation of rotational head movement is studied by performing finite element (FE) simulations of oblique impact on flat and helmet shape specimens. The performance of composite foam with respect to parameters such as compliance of the matrix foam and the number, size and cross-sectional shape of the foam columns is explored in detail, and subsequently an optimized structure is proposed. The simulation results show that using composite foam instead of single-layer foam, the rotational acceleration and velocity of the headform can be significantly reduced. The parametric study indicates that using a more compliant matrix foam and by increasing the number of columns in the composite foam configuration, the rotation can be further mitigated. This was confirmed by experimental results. The simulation results were also analyzed based on global head injury criteria such as head injury criterion, rotational injury criterion, brain injury criterion and generalized acceleration model for brain injury threshold which further confirmed the superior performance of composite foam versus single-layer homogeneous expanded polystyrene foam. The findings of simulations give invaluable information for design of protective helmets or, for instance, headliners for the automotive industry.

2015-06-01

Tubal sterilization during the immediate postpartum period is 1 of the most common forms of contraception in the United States. This time of the procedure has the advantage of 1-time hospitalization, which results in ease and convenience for the woman. The US Collaborative Review of Sterilization Study indicates the high efficacy and effectiveness of postpartum tubal sterilization. Oral and written informed consent is the ethical and legal standard for the performance of elective tubal sterilization for permanent contraception for all patients, regardless of source of payment. Current health care policy and practice regarding elective tubal sterilization for Medicaid beneficiaries places a unique requirement on these patients and their obstetricians: a mandatory waiting period. This requirement originates in decades-old legislation, which we briefly describe. We then introduce the concept of health care justice in professional obstetric ethics and explain how it originates in the ethical concepts of medicine as a profession and of being a patient and its deontologic and consequentialist dimensions. We next identify the implications of health care justice for the current policy of a mandatory 30-day waiting period. We conclude that Medicaid policy allocates access to elective tubal sterilization differently, based on source of payment and gender, which violates health care justice in both its deontologic and consequentialist dimensions. Obstetricians should invoke health care justice in women's health care as the basis for advocacy for needed change in law and health policy, to eliminate health care injustice in women's access to elective tubal sterilization.

Factors That Influence Mandatory Child Abuse Reporting Attitudes of Pediatric Nurses in Korea.

Science.gov (United States)

Lee, In Sook; Kim, Kyoung Ja

This study aimed to identify knowledge of child abuse, awareness of child abuse reporting, factors that influence attitudes toward mandatory reporting, and professionalism among a sample of pediatric nurses in Korea. One hundred sixteen pediatric nurses working at two university hospitals in Korea took part in the study and completed self-administered questionnaires. The data were analyzed using descriptive statistics, t tests, analysis of variance, Pearson correlation coefficients, and hierarchical regression analysis. Knowledge of child abuse, awareness of child abuse reporting, and attitudes toward mandatory reporting were low. Regarding nursing professionalism, social perceptions had the lowest mean score and nursing autonomy had the highest mean score. Attitudes toward mandatory reporting significantly correlated with professionalism. In the hierarchical regression model, the influences of nursing autonomy and intentions to report child abuse on attitudes toward mandatory reporting were statistically significant (F = 2.176, p = .013), explaining 32% of the variation in attitudes toward mandatory reporting. The results of this study could be used to improve systems and policies addressing child abuse and to further develop reporting procedures for identifying children at risk of abuse, to ensure their protection as a professional responsibility.

The pickup of visual information is critical for controlling movement and maintaining situational awareness in dangerous situations. Altered coordination while wearing protective equipment may impact the likelihood of injury or death. This investigation examined the consequences of load magnitude and distribution on situational awareness, segmental coordination and head gaze in several protective equipment ensembles. Twelve soldiers stepped down onto force plates and were instructed to quickly and accurately identify visual information while establishing marksmanship posture in protective equipment. Time to discriminate visual information was extended when additional pack and helmet loads were added, with the small increase in helmet load having the largest effect. Greater head-leading and in-phase trunk-head coordination were found with lighter pack loads, while trunk-leading coordination increased and head gaze dynamics were more disrupted in heavier pack loads. Additional armour load in the vest had no consequences for Time to discriminate, coordination or head dynamics. This suggests that the addition of head borne load be carefully considered when integrating new technology and that up-armouring does not necessarily have negative consequences for marksmanship performance. Practitioner Summary: Understanding the trade-space between protection and reductions in task performance continue to challenge those developing personal protective equipment. These methods provide an approach that can help optimise equipment design and loading techniques by quantifying changes in task performance and the emergent coordination dynamics that underlie that performance.

Cost Analysis of Noninvasive Helmet Ventilation Compared with Use of Noninvasive Face Mask in ARDS

Full Text Available Intensive care unit (ICU costs have doubled since 2000, totalling 108 billion dollars per year. Acute respiratory distress syndrome (ARDS has a prevalence of 10.4% and a 28-day mortality of 34.8%. Noninvasive ventilation (NIV is used in up to 30% of cases. A recent randomized controlled trial by Patel et al. (2016 showed lower intubation rates and 90-day mortality when comparing helmet to face mask NIV in ARDS. The population in the Patel et al. trial was used for cost analysis in this study. Projections of cost savings showed a decrease in ICU costs by $2527 and hospital costs by $3103 per patient, along with a 43.3% absolute reduction in intubation rates. Sensitivity analysis showed consistent cost reductions. Projected annual cost savings, assuming the current prevalence of ARDS, were $237538 in ICU costs and $291682 in hospital costs. At a national level, using yearly incidence of ARDS cases in American ICUs, this represents $449 million in savings. Helmet NIV, compared to face mask NIV, in nonintubated patients with ARDS, reduces ICU and hospital direct-variable costs along with intubation rates, LOS, and mortality. A large-scale cost-effectiveness analysis is needed to validate the findings.

To decrease the risk of transmission of hospital-associated transmission of influenza and pertussis through mandatory vaccination of staff. A mandatory influenza and toxoid-diphtheria toxoid-acellular pertussis program was implemented systemwide. A structured vaccine exemption program was implemented for those requesting a medical and/or religious/moral/ethical exemption. Systemwide influenza vaccination rates increased from 67% historically, 76.2% in the 2012 to 2013 influenza season, to 94.7% in 2013 to 2014 with an overall compliance rate of 97.8%. Toxoid-diphtheria toxoid-acellular pertussis vaccination rates systemwide reached 94.9%, with an overall compliance rate of 98%. Higher rates were experienced at individual hospital facilities compared with the corporate location. Successful vaccination campaign outcomes can be achieved through diligent enforcement of mandatory vaccination, masking, and other infection prevention procedures.

This bulletin contains information about activities of the Nuclear Regulatory Authority of the Slovak Republic (UJD). In this leaflet the legislation activities of the UJD are presented. The Nuclear Regulatory Authority (UJD) of the Slovak Republic, as the central body, performs legislative activities within its competence and defines binding criteria in the area of nuclear safety. In the area of nuclear safety the Act No.130/1998 Coll. 'on peaceful use of nuclear energy' (Atomic Act) is the principal document which came into force on July 1, 1998. Based on the Atomic Act UJD issued decrees on special materials and installations, limits for maximum quantities of nuclear materials at which nuclear damage is not presumed. Furthermore, the regulations are issued which deal with provision of physical protection of nuclear material and radioactive waste, professional ability of employees at nuclear installations, registration and control of nuclear materials, emergency planning for the case of an incident or an events on nuclear installations at their decommissioning, transportation of nuclear materials and radioactive waste. Simultaneously, other 6 regulations are just before the before the completion and they are in various stages of the of the legislative process. In addition, UJD performs remarkable activities in legislative area by preparation of comments to drafts of other relating generally binding legal provisions of the Slovak Republic. UJD also acts as the participant of the review procedure in the area of technical standards and publication. UJD also issues documents which have character of the recommendations, so called safety guides. These guides contain methods and approach how to meet safety requirements presented in binding documents, as acts and decrees. In accordance with the Atomic act it is possible to use nuclear energy or make business in the area of nuclear energy only the basis of the authorisation issued by UJD. Authorisations are following

From 3 to 17 June, the HSE Unit, in collaboration with the Reception and Access Control Service, led a campaign targeting CERN cyclists.   Photo: Laëtitia Wohlgemuth. In exchange for vouchers distributed by the security guards, 195 persons received a helmet and a reflective vest as well as documents on safety issues (ex: how to adjust one’s safety helmet properly; how to avoid blind spots; what is the required equipment for bikes and bike users, etc.). These persons also took part in a survey that contained questions on their cycling habits and level of knowledge on bike safety issues. It appeared that, for instance, 43% of the participants were aware that wearing a reflective vest is mandatory whenever visibility is poor (in France). 95% gave particular attention to the need to protect their heads (by assuming that wearing a helmet is either “mandatory” or “highly recommended”). The HSE Unit provided the participants with further i...

European Union pediatric legislation jeopardizes worldwide, timely future advances in the care of children with cancer.

Science.gov (United States)

Rose, Klaus

2014-02-01

Diagnosis of childhood cancer is no longer an automatic death sentence, but it has not lost all of its horror. Drugs, surgery, radiation, and clinical trials have advanced our capacity to handle these cancers, but pediatric cancers still face challenges. Pediatric pharmaceutical legislation was introduced in the United States in 1997 and has triggered many clinical trials that have helped us better understand what drugs do to a child's body and vice versa. Following the US precedence, the European Union introduced its own legislation. The US legislation was designed to generate additional pediatric data and balances between mandatory requirements and voluntary incentives. The US legislation was designed to mandate full registration of all new drugs for children whenever there is any potential pediatric use. The purpose of this article is to discuss unintended negative consequences of the legislation of the European Medicines Agency (EMA). We analyzed the effects of the EU pediatric legislation with respect to the history of the emergence of modern drugs, pediatric clinical pharmacology, and the development of drugs for pediatric malignancies. No new drug can be registered in the European Union without a detailed pediatric investigation plan (PIP) approved by the EMA's Pediatric Committee (PDCO). This has moved the discussion of the pediatric aspects of drug development to an earlier stage and has increased public awareness. It also has brought industry and pediatric oncologists closer together. However, in a review of >100 PDCO PIP decisions in childhood cancer, we found a lack of balance between the legitimate desire to include children in drug development and the common sense needed in the complex worlds of drug development and pediatric oncology. Many decisions appeared to have been based on both exaggerated assumptions about the frequency of childhood malignancies and the feasibility of the clinical trials proposed. Pharmaceutical companies are being forced

How not to argue against mandatory ethics review.

Science.gov (United States)

Hunter, David

2013-08-01

There is considerable controversy about the mandatory ethics review of research. This paper engages with the arguments offered by Murray Dyck and Gary Allen against mandatory review, namely, that this regulation fails to reach the standards that research ethics committees apply to research since it is harmful to the ethics of researchers, has little positive evidence base, leads to significant harms (through delaying valuable research) and distorts the nature of research. As these are commonplace arguments offered by researchers against regulation it is useful to assess their strength and the conclusion that they are taken to support, namely, that we ought to move back to a system of trust in researchers without compulsory regulation. Unfortunately, these arguments are at best weak and to some degree come into conflict in terms of supporting the desired conclusion.

Legislation for nuclear disaster

International Nuclear Information System (INIS)

Nagata, Shozo

2012-01-01

Fukushima nuclear disaster accident clarified problems on nuclear-related legislation and its application. Legislation for nuclear disaster (LNA) could not respond to severe accident because assumed size of accident was not enough. After emergency event corresponding to the article 15 of LNA, was reported by the operator, more than two hours passed by the issuance of Emergency State Declaration. Off-site center could not work at all. This article reviewed outline of LNA and introduced discussion on the reform of legislation and its application. Reform discussion should be focused on swift and effective response readiness to emergency: 1) operator's substantial nuclear emergency drilling, (2) reinforcement of government's headquarters for emergency response, (3) after nuclear emergency, government's headquarters remained to enhance resident's safety from radiation hazard and (4) enactment of nuclear emergency preparedness guidelines for local communities.

Legislative coalitions with incomplete information.

Science.gov (United States)

Dragu, Tiberiu; Laver, Michael

2017-03-14

In most parliamentary democracies, proportional representation electoral rules mean that no single party controls a majority of seats in the legislature. This in turn means that the formation of majority legislative coalitions in such settings is of critical political importance. Conventional approaches to modeling the formation of such legislative coalitions typically make the "common knowledge" assumption that the preferences of all politicians are public information. In this paper, we develop a theoretical framework to investigate which legislative coalitions form when politicians' policy preferences are private information, not known with certainty by the other politicians with whom they are negotiating over what policies to implement. The model we develop has distinctive implications. It suggests that legislative coalitions should typically be either of the center left or the center right. In other words our model, distinctively, predicts only center-left or center-right policy coalitions, not coalitions comprising the median party plus parties both to its left and to its right.

Impact of the legislation on electric utilities

1982-01-01

The possible impact of Federal nuclear waste legislation on electric utilities is discussed. The proposed legislation will set forth a well defined program enabling utilities with nuclear plants to make long term plans under a statutory mandate committed to an available technology and implementation timetable. The legislation includes the necessary specificity for the utility companies to fulfill their responsibilities in describing their waste disposal plans to their customers, the concerned public, and state and local legislators

Medicine, psychiatry and euthanasia: an argument against mandatory psychiatric review.

Science.gov (United States)

Parker, M

2000-04-01

The paper critically appraises the argument that requests for active assistance to die should be subject to mandatory psychiatric assessment. The argument for mandatory psychiatric assessment is usually supported by an appeal to the need for safeguards against errors and omissions in both the diagnosis of psychiatric conditions affecting the terminally ill and the exploration of the meanings of their requests. This intuitively appealing view is challenged through a broader analysis which examines connections between medicine's traditional adherence to the moral distinction between acts and omissions and the following issues: the historical relationship between medical practice and dying, the recent development of research into treatment-withdrawal decisions, the scientific status of psychiatry, the logic of rationality and decision-making competence. The analysis reveals a number of hitherto unexamined and unacknowledged influences which would make psychiatric review of requests for assisted death a much less objective and impartial process than is assumed. Mandatory psychiatric review is an instance of the medicalisation of death and dying which could abridge the freedom of certain individuals to make decisions about their deaths.

The Senate passed 69 to 6 legislation to provide a comprehensive nuclear waste policy. This legislation restates some things the Department of Energy is already doing. It modifies some others, and in some cases it provides new authorities, principally in those areas of state participation and in the area of financing of the program. Some of the provisions of the Senate bill are: schedule for a number of items in the disposal of nuclear waste, the first being an area referred to as away-from reactor storage; a timetable for geologic disposal; a plan for the long-term storage of nuclear waste for spent fuels; a financing mechanism; and states participation

Acceleration-based methodology to assess the blast mitigation performance of explosive ordnance disposal helmets

Science.gov (United States)

Dionne, J. P.; Levine, J.; Makris, A.

2018-01-01

To design the next generation of blast mitigation helmets that offer increasing levels of protection against explosive devices, manufacturers must be able to rely on appropriate test methodologies and human surrogates that will differentiate the performance level of various helmet solutions and ensure user safety. Ideally, such test methodologies and associated injury thresholds should be based on widely accepted injury criteria relevant within the context of blast. Unfortunately, even though significant research has taken place over the last decade in the area of blast neurotrauma, there currently exists no agreement in terms of injury mechanisms for blast-induced traumatic brain injury. In absence of such widely accepted test methods and injury criteria, the current study presents a specific blast test methodology focusing on explosive ordnance disposal protective equipment, involving the readily available Hybrid III mannequin, initially developed for the automotive industry. The unlikely applicability of the associated brain injury criteria (based on both linear and rotational head acceleration) is discussed in the context of blast. Test results encompassing a large number of blast configurations and personal protective equipment are presented, emphasizing the possibility to develop useful correlations between blast parameters, such as the scaled distance, and mannequin engineering measurements (head acceleration). Suggestions are put forward for a practical standardized blast testing methodology taking into account limitations in the applicability of acceleration-based injury criteria as well as the inherent variability in blast testing results.

Mandatory policy: Most successful way to maximize fortification’s effect on vitamin and mineral deficiency

Directory of Open Access Journals (Sweden)

Sarah Zimmerman

2014-12-01

Full Text Available Background: Damaging effects of vitamin and mineral deficiencies contribute to health and development problems throughout the world. Food fortification has substantially improved nutrition-related health conditions in many countries, but opportunities for fortification are not fully utilized. Where food fortification is considered, leaders have to determine whether fortification should be mandatory or voluntary. Objective: This article explores experiences with mandatory wheat flour fortification as compared to voluntary fortification to offer insight for policies related to any type of food fortification. Mandatory fortification means the country requires the addition of specific nutrients at predetermined levels to specified foods or food products. Voluntary policies allow food manufacturers to enrich their products but do not require them to do so. Results: Mandatory fortification is more likely than voluntary fortification to reach a high proportion of the population and hence achieve the desired health impact. Mandatory fortification does not require consumers to change food purchasing preferences, it distributes the health benefits more equitably than voluntary fortification across a population, it establishes safe levels of included nutrients, and it is not subject to the food manufacturers’ marketing investments or discretion. Conclusion: The health benefits of mandatory fortification are most likely to be achieved and sustained if national, multi-sector leaders develop a cooperative approach for appropriate food fortification policies that can be feasibly implemented and effectively monitored. Mandatory fortification, however, requires high-level commitment through the political process. Policy makers must contend with possible criticism that it interferes with personal choices or may cause unintended health problems.

Evolution of European Union legislation of herbal medicinal products and its transposition to national legislation in 1965-2007: case Finland.

Science.gov (United States)

Koski, Sari M; Laitinen-Parkkonen, Pirjo; Airaksinen, Marja

2015-01-01

The study aim was to explore the progress of legislation relating to herbal medicinal products in the European Union and compare it with the corresponding progress of the legislation in Finland in 1965-2007. The study was carried out using content analysis. Data were searched from publicly available European Union directives and national acts. All definitions and safety-related requirements for herbal medicinal products were identified. The transposition of safety-related requirements into the national legislation was studied. Medicinal products from plant origins have been part of the European Union legislation since 1965. Most plant-based products have not initially been regarded as medicinal products but rather as some kind of medicine-like products. The official definition of herbal medicinal products was introduced in Directive 2004/24/EC and implemented into the Finnish legislation with the terminology to recognise herbal medicinal products as part of medicinal products. The current safety-related requirements of medicinal products concern analogously herbal medicinal products. Herbal medicinal products have had different definitions in pharmaceutical legislation over the study period in the European Union and Finland. The current definition places herbal medicinal products more clearly under the medicinal products' legislation. Safety-related requirements are now practically identical for all medicinal products. Transposition of the European Union legislation into the national legislation in Finland is apparent. Copyright © 2013 John Wiley & Sons, Ltd.

HMD (head-mounted display) is an important virtual reality device, which has played a vital role in VR application system. Compared with traditional HMD which cannot be applied in the daily life owing to their disadvantage on the price and performance, a new universal and smart Helmet-Mounted Display of large FOV uses excellent performance and widespread popularity as its starting point. By adopting simplified visual system and transflective system that combines the transmission-type and reflection-type display system with transflective glass based on the Huggens-Fresnel principle, we have designed a HMD with wide field of view, which can be easy to promote and popularize. Its resolution is 800*600, and field of view is 36.87°(vertical)* 47.92°(horizontal). Its weight is only 1080g. It has caught up with the advanced world levels.

Legislating for advocacy: The case of whistleblowing.

Science.gov (United States)

Watson, Chanel L; O'Connor, Tom

2017-05-01

The role of nurses as patient advocates is one which is well recognised, supported and the subject of a broad body of literature. One of the key impediments to the role of the nurse as patient advocate is the lack of support and legislative frameworks. Within a broad range of activities constituting advocacy, whistleblowing is currently the subject of much discussion in the light of the Mid Staffordshire inquiry in the United Kingdom (UK) and other instances of patient mistreatment. As a result steps to amend existing whistleblowing legislation where it exists or introduce it where it does not are underway. This paper traces the development of legislation for advocacy. The authors argue that while any legislation supporting advocacy is welcome, legislation on its own will not encourage or enable nurses to whistleblow.

Mandatory IFRS adoption and executive compensation: Evidence from China

Directory of Open Access Journals (Sweden)

Qingchuan Hou

2014-03-01

Full Text Available This study investigates how the mandatory adoption of International Financial Reporting Standards (IFRS affects the contractual benefits of using accounting information to determine executive compensation in China. After controlling for firm and corporate governance characteristics, we find strong evidence supporting the positive role of mandatory IFRS adoption on the accounting-based performance sensitivity of executive compensation. Subsample analysis suggests that improvements in accounting-based performance sensitivity after IFRS adoption differ across regions with various levels of institutional quality and across firms that are affected to a different extent by the adoption. Additional analysis supports the argument that the positive effects of IFRS adoption on the use of accounting performance in executive compensation are driven by the reduction in accounting conservatism associated with IFRS adoption.

Mandatory reporting of greenhouse gas emissions from buildings: Stakeholders’ opinions in Hong Kong

International Nuclear Information System (INIS)

Lai, Joseph H.K.

2014-01-01

Mandatory reporting of greenhouse gas (GHG) emissions, which is intended to help combat global warming, has been increasingly implemented across the world. For buildings in Hong Kong, however, GHG reporting remains entirely voluntary even though the government has issued a set of guidelines to facilitate building owners and managers to quantify GHG emissions from buildings. Aimed at understanding stakeholders’ opinions on whether, and to what extent, the GHG reporting should be made mandatory, a study involving a questionnaire survey was carried out. Analysis of the opinions revealed that the majority supported making the reporting mandatory for office, hotel/hostel, and industrial buildings. Generally more support was received from those who were highly experienced, employees of non-government public organisations, academics/researchers, or qualified carbon/energy auditors. Their agreement on requiring reporting of activities under scopes 1 and 2 of the GHG Protocol was stronger than that for the scope 3 activities. Reporting of paper waste disposal attracted the weakest support. The reasons for not supporting the mandatory policy, including resource constraint and financial and knowledge barriers that confront the stakeholders, were identified. The findings of this study serve as reference for energy policy makers. - Highlights: • Majority supported mandatory reporting for office and hotel/hostel buildings. • More support was given for reporting of scopes 1 and 2 of the GHG Protocol. • Reporting for paper waste disposal received the weakest support. • Main hurdles were resource constraint and financial and knowledge barriers

From Conciliation to Mediation in Family Disputes-Harmonization of Croatian Family Legislation on Peaceful Resolution of Family Disputes with EU law

Directory of Open Access Journals (Sweden)

Paula Poretti

2015-01-01

Full Text Available The reform process of family law was initiated with one aim to promote protection of family and children and harmonize Croatian law with European and international standards in this field. In this respect, the intervention institute governed by Croatian family law with the purpose to facilitate reconciliation or in cases where reconciliation between spouses is not achieved, to provide information regarding legal consequences of divorce and possibly to achieve agreement between spouses as for their relationship in future was deemed inadequate in regards to the approach provided by European documents on regulation of peaceful resolution of family disputes. Under the influence thereof, new family legislation redefines intervention and introduces mandatory counselling and family mediation as foundations of the system of alternative dispute resolution of all family disputes in Croatian law.

Equality, Legal Certainty and Tax Legislation in the Netherlands
Fundamental Legal Principles as Checks on Legislative Power: A Case Study

Directory of Open Access Journals (Sweden)

Hans Gribnau

2013-03-01

Full Text Available Fundamental legal principles may function as a check on legislative power protecting citizens against arbitrary interferences with their liberty. This contribution deals with the principle of equality and the principle of certainty. First, the testing of legislation against the principle of equality is presented as a case study of constitutional review. In the Netherlands, the constitutional dialogue between the legislator and the Dutch Supreme Court revolving around the principle of equality demonstrates a fair amount of subtle details. As a result, constitutional review can hardly be called an all or nothing affair.Secondly, retroactive tax legislation is dealt with. The legislator does seem to take the principle of legal certainty, another fundamental legal principle, quite seriously, although no testing of statutory legislation is possible by the courts. With regard to retroactive tax legislation the Government has committed itself in a memorandum, requested by Parliament, to adhere to rules of conduct with regard to different situations where it deems retroactive tax legislation to be justified. Thus, a soft law instrument facilitates a dialogue between different partners in the business of law-making.

Legislative vulnerability of minority groups.

Science.gov (United States)

Paula, Carlos Eduardo Artiaga; Silva, Ana Paula da; Bittar, Cléria Maria Lôbo

2017-12-01

Minorities are in an inferior position in society and therefore vulnerable in many aspects. This study analyzes legislative vulnerability and aims to categorize as "weak" or "strong" the protection conferred by law to the following minorities: elderly, disabled, LGBT, Indians, women, children/ adolescents and black people. In order to do so, it was developed a documental research in 30 federal laws in which legal provisions were searched to protect minorities. Next, the articles were organized in the following categories: civil, criminal, administrative, labor and procedural, to be analyzed afterwards. Legal protection was considered "strong" when there were legal provisions that observed the five categories and "weak" when it did not meet this criterion. It was noted that six groups have "strong" legislative protection, which elides the assertion that minorities are outside the law. The exception is the LGBT group, whose legislative protection is weak. In addition, consecrating rights through laws strengthens the institutional channels for minorities to demand their rights. Finally, it was observed that the legislative protection granted tominorities is not homogeneous but rather discriminatory, and there is an interference by the majority group in the rights regulation of vulnerable groups.

Lack of Energy Efficiency Legislation in the Malaysian Building Sector Contributes to Malaysia’s Growing GHG Emissions

Directory of Open Access Journals (Sweden)

Zaid Suzaini M.

2014-01-01

Full Text Available Malaysia’s carbon emissions grew by +235.6% from 1990 to 2005, largely due to an increase in national energy demand of 210.7% from 1990 to 2004. This unparalleled carbon emission growth, along with business-as-usual (BAU practices will put Malaysia at high risk for carbon lock-in and a very unsustainable path of development. Malaysia clearly needs to make significant and urgent changes in its policy, economy, industries and lifestyle in order to reduce its climate change impacts. In 2010 Malaysia announced a voluntary commitment to reduce 40% of its greenhouse gases (GHG emissions by 2020 (from 1990 levels. Without emissions mitigation and conservation policies, Malaysia is unlikely to meet its emissions reduction targets. Presently, Malaysia has no energy efficiency legislation in its growing building sector. This paper reviews existing building policies and energy efficiency measures in Malaysia and highlights the need to implement mandatory energy efficiency building codes in reducing the sector’s impact on climate change.

2014-01-01

For several years, the use of administrative data in mandatory quality measurement has been requested by several stakeholders in Germany. Main advantages of using administrative data include the reduction of documentary expenditures and the possibility to perform longitudinal quality analyses across different healthcare units. After a short introduction, a brief overview of the current use of administrative data for mandatory quality assurance as well as current developments is given, which will then be further exemplified by decubital ulcer prophylaxis. By using administrative data coding expenditures in this clinical area could be reduced by nine million data fields. At the same time the population analysed was expanded resulting in a more than tenfold increase in potentially quality-relevant events. Finally, perspectives, further developments, possibilities as well as limits of quality measurement with administrative data are discussed. Copyright © 2014. Published by Elsevier GmbH.

The Political Economy of Collective Labour Legislation in Taiwan

Directory of Open Access Journals (Sweden)

James W. Y. Wang

2010-01-01

Full Text Available This article provides a seminal analysis of collective labour legislation in Taiwan. A chronological review of Taiwan’s legislative process suggests that the context of incorporation, institutional framework, mechanisms for delivering reforms, and sequence of reforms together shape the legislative outcomes of labour reforms at the collective level. While most labour legislation was revised and passed after the preceding sequence of economic transition, the reform of collective labour rights was greatly constrained by the flexible labour-market structure. In order for politicians to form new alliances with labour organizations, legislation of collective labour rights was a strategy to cultivate support during electoral periods. Consequently, the industrial relations changed following the enactment of substantial reform-oriented labour legislation. Theore-tically, the historical analysis of legislative procedure unveils evolutionary reform paths for collective labour rights in new democracies. At the same time, empirically, Taiwan demonstrates an alternative reform path in combination with incremental steps and progressive agendas. For new democracies of small economy, a window of opportunity for the progress in collective labour legislation remains open today, albeit with limitations.

The notion of 'incrementalism', formulated by Aaron Wildavsky in the 1960's, has been extremely influential in the public budgeting literature. In essence, it entails the claim that legislators engaged in budgetary policymaking accept past allocations, and decide only on the allocation of increments to revenue. Wildavsky explained incrementalism with reference to the cognitive limitations of lawmakers and their desire to reduce conflict. This paper uses a legislative bargaining framework to u...

Measuring the loss of consumer choice in mandatory health programmes using discrete choice experiments.

Science.gov (United States)

Parkinson, Bonny; Goodall, Stephen; Norman, Richard

2013-04-01

Economic evaluation of mandatory health programmes generally do not consider the utility impact of a loss of consumer choice upon implementation, despite evidence suggesting that consumers do value having the ability to choose. The primary aim of this study was to explore whether the utility impact of a loss of consumer choice from implementing mandatory health programmes can be measured using discrete choice experiments (DCEs). Three case studies were used to test the methodology: fortification of bread-making flour with folate, mandatory influenza vaccination of children, and the banning of trans-fats. Attributes and levels were developed from a review of the literature. An orthogonal, fractional factorial design was used to select the profiles presented to respondents to allow estimation of main effects. Overall, each DCE consisted of 64 profiles which were allocated to four versions of 16 profiles. Each choice task compared two profiles, one being voluntary and the other being mandatory, plus a 'no policy' option, thus each respondent was presented with eight choice tasks. For each choice task, respondents were asked which health policy they most preferred and least preferred. Data was analysed using a mixed logit model with correlated coefficients (200 Halton draws). The compensating variation required for introducing a programme on a mandatory basis (versus achieving the same health impacts with a voluntary programme) that holds utility constant was estimated. Responses were provided by 535 participants (a response rate of 83 %). For the influenza vaccination and folate fortification programmes, the results suggested that some level of compensation may be required for introducing the programme on a mandatory basis. Introducing a mandatory influenza vaccination programme required the highest compensation (Australian dollars [A$] 112.75, 95 % CI -60.89 to 286.39) compared with folate fortification (A$18.05, 95 % CI -3.71 to 39.80). No compensation was

Does State Legislation Improve Nursing Workforce Diversity?

Travers, Jasmine; Smaldone, Arlene; Cohn, Elizabeth Gross

2015-08-01

A health-care workforce representative of our nation's diversity is a health and research priority. Although racial and ethnic minorities represent 37% of Americans, they comprise only 16% of the nursing workforce. The purpose of this study was to examine the effect of state legislation on minority recruitment to nursing. Using data from the National Conference of State Legislatures, American Association of Colleges of Nursing, and U.S. census, we compared minority enrollment in baccalaureate nursing programs of states (Texas, Virginia, Michigan, California, Florida, Connecticut, and Arkansas) before and 3 years after enacting legislation with geographically adjacent states without legislation. Data were analyzed using descriptive and chi-square statistics. Following legislation, Arkansas (13.8%-24.5%), California (3.3%-5.4%), and Michigan (8.0%-10.0%) significantly increased enrollment of Blacks, and Florida (11.8%-15.4%) and Texas (11.2%-13.9%) significantly increased enrollment of Hispanic baccalaureate nursing students. States that tied legislation to funding, encouragement, and reimbursement had larger enrollment gains and greater minority representation. © The Author(s) 2015.

Trails provide opportunities for recreation, transportation and activity. The purpose of this article is to describe state legislation related to community trails, to analyze legislation content, and to evaluate legislation on inclusion of evidence-informed elements. State trail legislation from 2001 to 2008 was identified using online legislative databases. An analysis of evidence-informed elements included in the legislation was conducted. These elements included: funding, liability, accessibility, connectivity, and maintenance. Of the total 991 trail bills, 516 (52.0%) were appropriations bills, of which 167 (32.2%) were enacted. We analyzed 475 (48%) nonappropriation trail bills of which 139 (29.3%) were enacted. The percentage of enactment of appropriations bills decreased over time while enactment of nonappropriations trail bills increased. Over half of the nonappropriations trail bills included at least 1 evidence-informed element, most commonly funding. Few bills contained liability, connectivity, accessibility, or maintenance. There is opportunity for providing evidence-informed information to policy-makers to potentially influence bill content. The number of bills with a funding element demonstrates that fiscal support for trails is an important policy lever that state legislatures may use to support trails. Lastly, trails should be considered in over-all state-level physical activity legislation to provide opportunities for communities to be active.

Full Text Available This paper looks at the topic of regulation of integrated reporting for listed companies, with the aim of contributing to the debate on the usefulness of introducing a mandatory regime, both from the perspective of integrated performance sustainability of companies and from that of relevance of information for providers of financial capital. The study is based on empirical research carried out on a sample composed of companies operating in territories where the adoption of integrated reporting is voluntary (Europe and those operating in a country where adoption is mandatory (South Africa. The research shows that (a in voluntary regimes, levels of integrated performance achieved by companies are higher; (b mandatory regulation produces positive effects on integrated performance levels in the medium term; (c integrated performance indicators are value-relevant, though having different levels of relevance under the two regimes examined.

State health agencies and the legislative policy process.

Science.gov (United States)

Williams-Crowe, S M; Aultman, T V

1994-01-01

A new era of health care reform places increasing pressure on public health leaders and agencies to participate in the public policy arena. Public health professionals have long been comfortable in providing the scientific knowledge base required in policy development. What has been more recent in its evolution, however, is recognition that they must also play an active role in leading and shaping the debate over policy. A profile of effective State legislative policy "entrepreneurs" and their strategies has been developed to assist health agencies in developing such a leadership position. Based on the experiences of State legislative liaison officers, specific strategies for dealing with State legislatures have been identified and are organized into five key areas--agency organization, staff skills, communications, negotiation, and active ongoing involvement. A public health agency must be organized effectively to participate in the legislative policy process. Typically, effective agencies centralize responsibility for policy activities and promote broad and coordinated participation throughout the organization. Playing a key role in the agency's political interventions, the legislative liaison office should be staffed with persons possessing excellent interpersonal skills and a high degree of technical competence. Of central importance to effective legislative policy entrepreneurship is the ability to communicate the agency's position clearly. This includes setting forward a focused policy agenda, documenting policy issues in a meaningful manner, and reaching legislators with the proper information. Once a matter is on the legislative agenda, the agency must be prepared to negotiate and build broad support for the measure. Finally, public health agencies must be active policy players. To take advantage of new opportunities for action, the public health (policy) leader must monitor the political environment continually.By working to anticipate and formulate

Mandatory Reporting of Human Trafficking: Potential Benefits and Risks of Harm.

English, Abigail

2017-01-01

Human trafficking, including both sex and labor trafficking, has profound consequences for the safety, health, and well-being of victims and survivors. Efforts to address human trafficking through prevention, protection, and prosecution are growing but remain insufficient. Mandatory reporting has the potential to bring victims and survivors to the attention of social service and law enforcement agencies but may discourage trafficked persons from seeking help, thereby limiting the ability of health care professionals to establish trust and provide needed care. States' experience in implementing child abuse laws can be useful in assessing the potential risks and benefits of mandatory reporting of human trafficking. © 2017 American Medical Association.

Accountability legislation: Implications for financial and performance reporting

Directory of Open Access Journals (Sweden)

Daphne Rixon

2012-03-01

Full Text Available The purpose of this case study is to first examine the implications of accountability legislation on the financial and performance reporting of a public sector agency in the Canadian province of Newfoundland and Labrador and secondly, to compare the level of accountability with Stewart’s (1984 ladder of accountability. This paper is based on the first phase of a two-phase study. The first phase focuses on the initial impacts of accountability legislation on agencies and the challenges created by the legislation’s ‘one size fits all’ approach. The second phase of this study will examine the impact of the legislation on stakeholders after it has been in operation for five years. The second phase will include interviews with stakeholders to ascertain the level of satisfaction with the new legislation. The first phase of the study is significant since it highlights how governments could consider stakeholder needs when drafting such legislation. This research contributes to the body of literature on stakeholder accountability since there is a paucity of research focused specifically on the impact of accountability legislation on public sector agencies. An important contribution of this paper is the introduction of a framework for legislated accountability reporting. The main theoretical frameworks used to analyse the findings are Stewart’s (1984 ladder of accountability in conjunction with Friedman and Miles (2006 ladder of stakeholder management and engagement.

Firework related injury and legislation: the epidemiology of firework injuries and the effect of legislation in Northern Ireland.

Science.gov (United States)

Fogarty, B J; Gordon, D J

1999-02-01

The efficacy of legislation in reducing firework associated injuries is uncertain as is the nature of the problem within the United Kingdom (UK). In September 1996 the legislation governing firework sale in Northern Ireland was relaxed thus equalling that of the rest of the UK. For the 2 years following the change in legislation we prospectively assessed those patients who were admitted with a firework injury over the Halloween period. We then compared these results with retrospective data for the 3 years prior to the change in firework law. In the pre-legislation series the mean number of patients admitted annually was 0.38 per 100,000 while in the post-legislation series the mean was 0.43 per 100,000. Blast injury to the hand was the commonest injury accounting for 53% of cases in both series. Burn injuries were the second commonest form of injury comprising 30% of all admissions. Of those admitted with a hand injury 47% had at least one finger terminalised and nearly half of those patients admitted with burns (44%) required skin grafting. We conclude that early evidence suggests that liberalisation of the law on firework sale has not resulted in a significant increase in firework related injuries requiring hospital admission.

Legislating Interprofessional Regulatory Collaboration in Nova Scotia

Directory of Open Access Journals (Sweden)

William Lahey

2013-10-01

Full Text Available To shift health professions regulation from traditional to ‘collaborative’ self-regulation, Nova Scotia has adopted legislation which will: make all self-regulating health professions members of the Regulated Health Professions Network; mandate the Network to facilitate voluntary collaboration among its members; and enable regulators to work together on investigations of patient complaints, to adjust scopes of practice on an ongoing basis and to adjudicate appeals of unsuccessful applicants for registration. The goals are to give health professions regulation the capacity to enable and support the functioning of interprofessional teams. The legislation was adopted primarily for two reasons: collaborative development and unanimous support by all of the province’s self-regulating professions; and alignment with the government’s health care reform agenda and its emphasis on collaborative team-based care. Contrary to the approach of several other provinces, the legislation will enable but not require regulators to collaborate on the premise that consensual collaboration is more likely to happen, to be meaningful and to yield tangible benefits. Support for this approach can be taken from the impressive collaborative work on which the legislation is based. Evaluation will be critical, and the five-year review required by the legislation will give Nova Scotia the opportunity to test not only the legislation but the ideas on which it is based. The extent of the legislation’s reliance on voluntary process will prove to be either its greatest strength or its greatest weakness.

New Ontario power legislation aims to protect consumers

Energy Technology Data Exchange (ETDEWEB)

Anon.

2000-09-01

New legislation designed to improve regulation of the electricity sector in Ontario was introduced by the provincial government in June 2000, the first such legislation since the government mandated an open electricity market with the Energy Competition Act of 1998. The new legislation is described as narrowly focused on putting limits on local power rate increases. The legislation was introduced in combination with a directive to the Ontario Energy Board, and is designed to ensure that the Board approves municipal electric utility rates only when certain conditions are met. The Energy Minister was at great pains to point out that the legislation should not be interpreted as the government interfering in the marketplace, it is merely to help the utility wires side of the business during a two-year transition period. Municipal authorities reacted unfavorably to the legislation because it appears to require them to return significant assets to their utilities, assets that they considered as theirs under municipal restructuring. Energy Probe, an environmental advocacy group, suggested an alternative to the legislation, i. e., the government should allow the price increases requested by the municipal utilities to go through, but to leave consumers whole, it should impose a windfall profits tax on municipal governments, use the proceeds to reduce debt retirement taxes in the electricity bill, a leftover from Ontario Hydro's debt and stranded nuclear waste liabilities, and eliminate the province's own electricity tax on consumers. No direct reaction has been received from the Minister to date. If the legislation is passed in its present form it will prevent municipalities from using windfall profits from their utilities to justify rate hikes.

The relationship between administrative court control and legislative control

The legislator can determine the extent of control of administrative courts by reduction of substantive conditions. The author has the opinion that the judicial control cannot be stricter than the legislative control. For the range of the control of administrative courts is decisive, to what extent the legislator is forced to proper legislative settlements.

Chief executives in many parliamentary democracies have the power to dissolve the legislature. Despite a well-developed literature on the endogenous timing of parliamentary elections, political scientists know remarkably little about the strategic use of dissolution power to influence policymaking....... To address this gap, we propose and empirically evaluate a theoretical model of legislative bargaining in the shadow of executive dissolution power. The model implies that the chief executive's public support and legislative strength, as well as the time until the next constitutionally mandated election...

ETHICS OF MANDATORY PREMARITAL HIV TESTING IN AFRICA: THE CASE OF GOMA, DEMOCRATIC REPUBLIC OF CONGO

RENNIE, STUART; MUPENDA, BAVON

2015-01-01

Despite decades of prevention efforts, millions of persons worldwide continue to become infected by the human immunodeficiency virus (HIV) every year. This urgent problem of global epidemic control has recently lead to significant changes in HIV testing policies. Provider-initiated approaches to HIV testing have been embraced by the Centers for Disease Control and Prevention and the World Health Organization, such as those that routinely inform persons that they will be tested for HIV unless they explicitly refuse (‘opt out’). While these policies appear to increase uptake of testing, they raise a number of ethical concerns that have been debated in journals and at international AIDS conferences. However, one special form of ‘provider-initiated’ testing is being practiced and promoted in various parts of the world, and has advocates within international health agencies, but has received little attention in the bioethical literature: mandatory premarital HIV testing. This article analyses some of the key ethical issues related to mandatory premarital HIV testing in resource-poor settings with generalized HIV epidemics. We will first briefly mention some mandatory HIV premarital testing proposals, policies and practices worldwide, and offer a number of conceptual and factual distinctions to help distinguish different types of mandatory testing policies. Using premarital testing in Goma (Democratic Republic of Congo) as a point of departure, we will use influential public health ethics principles to evaluate different forms of mandatory testing. We conclude by making concrete recommendations concerning the place of mandatory premarital testing in the struggle against HIV/AIDS. PMID:19143089

2015-07-01

Baseball maintains one of the highest impact injury rates in all athletics. A principal causative factor is the "beanball," referring to a pitch thrown directly at a batter's head. Frequent morbidities elicited demand for the development of protective gear development in the 20th century. In this setting, Dr. Walter Dandy was commissioned to design a "protective cap" in 1941. His invention became widely adopted by professional baseball and inspired subsequent generations of batting helmets. As a baseball aficionado since his youth, Walter Dandy identified a natural partnership between baseball and medical practice for the reduction of beaning-related brain injuries. This history further supports the unique position of neurosurgeons to leverage clinical insights, inform innovation, and expand service to society.

Marco Antonio Conejero

2010-09-01

Full Text Available Scenarios depicting targets concerning mandatory bio-fuel blending are critical to the strategic planning of food and bio-energy production chains and their design is the purpose of this paper. Each scenario tells a story about how various elements might interact under given conditions. The method herein utilized is primarily based on Schoemaker´s (1995 and Schwartz´s (1991 earlier proposals. A six step framework is followed: i identify the focal issue; ii summarize current mandatory blending targets; iii identify the driving forces as of a macro-environmental analysis; iv validate driving forces with specialists; v rank such key forces by importance before uncertainties, building a correlation matrix; vi design the scenarios. Finally, three alternative scenarios, relative to the adoption on behalf of countries, by the year 2020, of mandatory bio-fuel blending targets, are proposed which might guide these countries’ decision makers when planning production systems.

Evidence and argument in policymaking: development of workplace smoking legislation

Directory of Open Access Journals (Sweden)

Bero Lisa A

2009-06-01

Full Text Available Abstract Background We sought to identify factors that affect the passage of public health legislation by examining the use of arguments, particularly arguments presenting research evidence, in legislative debates regarding workplace smoking restrictions. Methods We conducted a case-study based content analysis of legislative materials used in the development of six state workplace smoking laws, including written and spoken testimony and the text of proposed and passed bills and amendments. We coded testimony given before legislators for arguments used, and identified the institutional affiliations of presenters and their position on the legislation. We compared patterns in the arguments made in testimony to the relative strength of each state's final legislation. Results Greater discussion of scientific evidence within testimony given was associated with the passage of workplace smoking legislation that provided greater protection for public health, regardless of whether supporters outnumbered opponents or vice versa. Conclusion Our findings suggest that an emphasis on scientific discourse, relative to other arguments made in legislative testimony, might help produce political outcomes that favor public health.

Moral autonomy in Australian legislation and military doctrine

Directory of Open Access Journals (Sweden)

Richard Adams

2013-09-01

Full Text Available Australian legislation and military doctrine stipulate that soldiers ‘subjugate their will’ to government, and fight in any war the government declares. Neither legislation nor doctrine enables the conscience of soldiers. Together, provisions of legislation and doctrine seem to take soldiers for granted. And, rather than strengthening the military instrument, the convention of legislation and doctrine seems to weaken the democratic foundations upon which the military may be shaped as a force for justice. Denied liberty of their conscience, soldiers are denied the foundational right of democratic citizenship and construed as utensils of the State. This article critiques the idea of moral agency in Australian legislation and military doctrine and is concerned with the obligation of the State to safeguard the moral integrity of individual soldiers, so soldiers might serve with a fully formed moral assurance to advance justice in the world. Beyond its explicit focus on the convention of Australian thought, this article raises questions of far-reaching relevance. The provisos of Australian legislation and doctrine are an analogue of western thinking. Thus, this discussion challenges many assumptions concerning military duty and effectiveness. Discussion will additionally provoke some reassessment of the expectations democratic societies hold of their soldiers.

'Pivotal politics' in US energy and climate legislation

International Nuclear Information System (INIS)

Skodvin, Tora

2010-01-01

In the 110th Congress (2007-2008) legislation related to climate change was introduced at a faster pace than in any previous Congress, yet it did not result in a corresponding increase in enacted climate-related laws. A pertinent example of the political infeasibility of climate policy change in the 110th Congress is the case of tax credit extensions for production of renewable energy. While this issue in itself was uncontroversial, the extensions were only adopted in the 11th hour, after innumerable failed attempts. With an analytical point of departure in Krehbiel's theory of pivotal politics, this paper seeks to identify pivotal legislators in the case of the tax credit extensions and discusses how changes in the composition of pivotal legislators in the 111th Congress (2009-2010) may impact the prospects of moving climate legislation more generally. The analysis indicates that a majority of the legislative pivots in the case of tax credit extensions were Republican senators representing coal-producing states. In the case of climate change, however, the regional dimension is likely to be more significant for Democratic voting behaviour. Thus, the opportunity space for climate legislation in the 111th Congress remains narrow even with a reinforced Democratic majority in Congress.

Environmental Legislation in China: Achievements, Challenges and Trends

Directory of Open Access Journals (Sweden)

Zhilin Mu

2014-12-01

Full Text Available Compared to the environmental legislation of many developed countries, China’s environmental legislation was initiated late, beginning in 1979, but nevertheless has obtained considerable achievements. As many as thirty environmental laws have provided rules regarding prevention and control of pollution, resource utilization, and ecological protection in China. However, China’s environmental legislation still faces a series of challenges and problems, including that the sustainable development concept has not yet been fully implemented, as well as presence of gaps and non-coordination phenomena between laws and regulations, unclear responsibility, imperfect system design, imbalance between rights and obligations, higher impacts resulted from the GDP-centralized economy, lack of operability and instruments in the legal content, as well as difficulty of public participation. In contrast, China’s environmental legislation has improved, as a result of learning from experience in developed countries and introducing innovations stimulated by domestic environmental pressure. Looking into the future, increased attention to environmental protection and ecological consciousness paid by China’s new leaders will bring a valuable opportunity to China’s further development concerning environmental legislation. In the future, there are prospects for the gradual improvement of legal approaches, continuous improvements of legislation to mitigate environmental problems, and more opportunities to strengthen public participation can be predicted.

A Dosimetric Evaluation of Conventional Helmet Field Irradiation Versus Two-Field Intensity-Modulated Radiotherapy Technique

International Nuclear Information System (INIS)

Yu, James B.; Shiao, Stephen L.; Knisely, Jonathan

2007-01-01

Purpose: To compare dosimetric differences between conventional two-beam helmet field irradiation (external beam radiotherapy, EBRT) of the brain and a two-field intensity-modulated radiotherapy (IMRT) technique. Methods and Materials: Ten patients who received helmet field irradiation at our institution were selected for study. External beam radiotherapy portals were planned per usual practice. Intensity-modulated radiotherapy fields were created using the identical field angles as the EBRT portals. Each brain was fully contoured along with the spinal cord to the bottom of the C2 vertebral body. This volume was then expanded symmetrically by 0.5 cm to construct the planning target volume. An IMRT plan was constructed using uniform optimization constraints. For both techniques, the nominal prescribed dose was 3,000 cGy in 10 fractions of 300 cGy using 6-MV photons. Comparative dose-volume histograms were generated for each patient and analyzed. Results: Intensity-modulated radiotherapy improved dose uniformity over EBRT for whole brain radiotherapy. The mean percentage of brain receiving >105% of dose was reduced from 29.3% with EBRT to 0.03% with IMRT. The mean maximum dose was reduced from 3,378 cGy (113%) for EBRT to 3,162 cGy (105%) with IMRT. The mean percent volume receiving at least 98% of the prescribed dose was 99.5% for the conventional technique and 100% for IMRT. Conclusions: Intensity-modulated radiotherapy reduces dose inhomogeneity, particularly for the midline frontal lobe structures where hot spots occur with conventional two-field EBRT. More study needs to be done addressing the clinical implications of optimizing dose uniformity and its effect on long-term cognitive function in selected long-lived patients

MANDATORY TAKEOVER BIDS ON ROMANIAN CAPITAL MARKET

2017-05-01

Full Text Available The Romanian Capital Market Law (Law no 297/2004 lays down rules regarding public offers (to buy or sell of securities admitted to trading on a regulated market. Such offers are not unknown in the general framework of companies’ regulations, i.e. Company Law no 31/1990. Actually a public limited liability company (joint stock company can use a public subscriptions (offering shares for sale to raise the registered capital for incorporation of the company or to increase the company’s share capital already established. But all such operations are voluntary decisions. The founders or the shareholders of the company are those who decide to launch a public subscriptions. Capital Market Law comes with something new and at least peculiar at first sight: mandatory takeover bid, meaning a mandatory public offer made by an offeror to the holders of the securities of a company (offeree to acquire all or some of those securities. Can someone be forced to buy securities on the regulated market? The Capital Market Law responds affirmatively, but only if such takeover bid follows or has as its objective the acquisition of control of the offeree company in accordance with national law. The takeover bid remains under supervision and authorization of the national authority of the Capital Market (FSA – Financial Supervisory Authority.

Autopsy issues in German Federal Republic transplantation legislation until 1997.

Science.gov (United States)

Schweikardt, Christoph

2014-01-01

This article analyzes the relevance of autopsy issues for German Federal Republic transplantation legislation until 1997 against the background of legal traditions and the distribution of constitutional legislative powers. It is based on Federal Ministry of Justice records and German Parliament documents on transplantation legislation. Transplantation and autopsy legislation started with close ties in the 1970s. Viewing transplantation legislation as relevant for future autopsy regulation contributed to the decision to stall transplantation legislation, because the interests of the federal government and the medical profession converged to avoid subsequent restrictions on the practice of conducting autopsies and procuring tissues for transplantation. Sublegal norms were insufficient for the prosecution of the organ trade and area-wide transplantation regulation after the reunification of Germany. In contrast to autopsy issues, legislative power for transplantation issues was extended to the federal level by an amendment to the constitution, allowing decision making for Germany as a whole.

Legislation on violence against women: overview of key components.

This study aimed to determine if legislation on violence against women (VAW) worldwide contains key components recommended by the Pan American Health Organization (PAHO) and the United Nations (UN) to help strengthen VAW prevention and provide better integrated victim protection, support, and care. A systematic search for VAW legislation using international legal databases and other electronic sources plus data from previous research identified 124 countries/territories with some type of VAW legislation. Full legal texts were found for legislation from 104 countries/territories. Those available in English, Portuguese, and Spanish were downloaded and compiled and the selection criteria applied (use of any of the common terms related to VAW, including intimate partner violence (IPV), and reference to at least two of six sectors (education, health, judicial system, mass media, police, and social services) with regard to VAW interventions (protection, support, and care). A final sample from 80 countries/territories was selected and analyzed for the presence of key components recommended by PAHO and the UN (reference to the term "violence against women" in the title; definitions of different types of VAW; identification of women as beneficiaries; and promotion of (reference to) the participation of multiple sectors in VAW interventions). Few countries/territories specifically identified women as the beneficiaries of their VAW legislation, including those that labeled their legislation "domestic violence" law ( n = 51), of which only two explicitly mentioned women as complainants/survivors. Only 28 countries/territories defined the main forms of VAW (economic, physical, psychological, and sexual) in their VAW legislation. Most highlighted the role of the judicial system, followed by that of social services and the police. Only 28 mentioned the health sector. Despite considerable efforts worldwide to strengthen VAW legislation, most VAW laws do not incorporate the key

An understanding of nurse educators' leadership behaviors in implementing mandatory continuing nursing education in China.

Science.gov (United States)

Xiao, Lily Dongxia

2008-09-01

Mandatory continuing nursing education is viewed as one way to develop registered nurses' continuing competencies. However, as has been argued internationally, it can also create a paradox in terms of learning to meet study requirements. Such paradox has been discussing in China since the implementation of mandatory continuing nursing education in 1996. Nurse educators, who develop continuing nursing education programs, appear to respond to the paradox differently associated with their leadership styles. This article reports a qualitative study aiming to gain an understanding of nurse educators' leadership behaviors in implementing mandatory continuing nursing education in China. Gadamer's philosophical hermeneutics underpins in-depth interviews with five nurse educators and data interpretation. Two categories of nurse educators, described as proactive educator and reactive educator, were identified and compared with two types of leadership styles described as transformational leader and transactional leader in the literature of educational leadership and continuing professional development. Proactive educators shared core attributors of transformational leaders and were able to relieve the paradox in mandatory continuing nursing education. Reactive educators however showed some attributors of transactional leaders and might escalate the paradox. Findings suggest further research in relation to the preparation of nurse educators.

DEVELOPMENTS IN THE CONSTITUTIONAL REVIEW. CONSTITUTIONAL COURT BETWEEN THE STATUS OF NEGATIVE LEGISLATOR AND THE STATUS OF POSITIVE CO-LEGISLATOR

Directory of Open Access Journals (Sweden)

Marieta Safta

2012-11-01

Full Text Available The study wants to emphasize that Constitutional Courts belonging to the European model depart from their traditional role as ”negative legislator” – which refers to the effect of their acts consisting in removal from the legal system of those rules contrary to the Basic Law -, becoming, to a certain extent, a ”positive legislator”. Official interpreters of the Constitution, Constitutional Courts assume, sometimes, a role of co-legislators, creating provisions they deduct from the Constitution - when controlling the absence of legislation or legislative omissions -, and revealing the content of constitutional and even infraconstitutional rules accordingly with the Constitution in their case-law, whose effects are nothing but specific forms of „impulse” or „coercion” of the legislator to proceed in a certain sense, and whose continuous development guides the evolution of the entire legal system. Case – law selected presents ways in which the Constitutional Court of Romania is associated to law-making activity. Without minimizing in any way its traditional role as "negative legislator", the study refers mainly to acts and situations that give expression to the creative role of the Constitutional Court of Romania.

To understand legislation combating counterfeit drugs in Hong Kong. This study consisted of two parts. In part I, counterfeit drugs–related ordinances and court cases were reviewed. In part II, indepth interviews of the stakeholders were described. Hong Kong. All Hong Kong ordinances were screened manually to identify those combating counterfeit drugs. Court cases were searched for each of the identified cases. Then, the relevant judgement justifications were analysed to identify sentencing issues. Indepth interviews with the stakeholders were conducted to understand their perceptions about such legislation. Trade Marks Ordinance, Patents Ordinance, Trade Descriptions Ordinance, and Pharmacy and Poisons Ordinance were current legislative items combating counterfeit drugs. Sentencing criteria depended on: intention to deceive, quantity of seized drugs, presence of expected therapeutic effect or toxic ingredients, previous criminal records, cooperativeness with Customs officers, honest confessions, pleas of guilty, types of drugs, and precautionary measures to prevent sale of counterfeit drugs. Stakeholders’ perceptions were explored with respect to legislation regarding the scale and significance of the counterfeit drug problem, penalties and deterrents, drug-specific legislation and authority, and inspections and enforcement. To plug the loopholes, a specific law with heavy penalties should be adopted. This could be supplemented by non-legal measures like education of judges, lawyers, and the public; publishing the names of offending pharmacies; and emphasising the role of pharmacists to the public.

An examination of outlaw motorcycle gangs and their involvement in the illicit drug market and the effectiveness of anti-association legislative responses.

Science.gov (United States)

Goldsworthy, Terry; McGillivray, Laura

2017-03-01

In 2013 the Queensland Government introduced criminal association and mandatory sentencing laws for members of outlaw motorcycle gangs (OMCGs). Forms of "criminal association" or "anti-bikie" laws have been introduced in several Australian jurisdictions, and recent High Court decisions upholding their constitutionality will ensure that they remain part of our justice landscape. Generally, the aims of these laws are to declare a specific organisation as "criminal" and impose various legal orders and offences that thwart the consorting of members and address organised crime, such as unexplained wealth regimes. There have been significant criticisms of these styles of association laws both here and internationally. The aim of this research is to show the extent of involvement of OMCGs in the drug trade and associated organised crime activity, and whether anti-association laws are an effective response to this type of organised criminal activity. This paper relied on six years of data outlining the criminal activity of OMCGs from the Queensland Police Service (QPS) obtained under the legislative framework of The Queensland Right to Information Act (RTI) 2009. Information obtained from the Queensland Commission into Organised Crime (2015) and Queensland Taskforce into organised crime legislation (2015) was also used. The data suggest that the role of OMCGs in the drug market has been overstated and is not as dominant as has been portrayed by government agencies and the popular media. Generally, OMCGs account for less than one percent of organised crime type activity. This is also true for drug type offences where OMCGs are responsible for less than one percent of offences. The findings show that the Queensland example has highlighted the ineffectiveness of the criminal association laws and the mandatory sentencing provisions in that they have had little impact on drug market activity and little success in the courts. The analysis presented here is twofold: an

Mandatory HIV testing gives rise to serious difficulties for applicants to Canada living with HIV. Applicant, physician and federal state employee work practices associated with mandatory HIV testing are analysed. These practices contribute to the ideological work of the Canadian state, where interest bounds up in the examination serve the state and not the applicant. Findings should be useful for Canadian immigration policy makers who wish to develop constructive and functional strategies to address issues that matter in people's lives

Musculoskeletal disorders are considered as a major issue affecting the health and well-being of active duty police. Discomfort from wearing mandatory equipment and sitting for long periods of time in fleet vehicles are workload factors linked to musculoskeletal disorders in police. This study aims to determine the prevalence of multi-site musculoskeletal pain among Swedish police and to explore the possible association to discomfort experience when wearing mandatory equipment and sitting for long periods in fleet vehicles. In this cross-sectional study responses from 4185 police were collected through a self-administered online survey including questions about physical work environment, mandatory equipment and musculoskeletal pain. Multi-site pain was determined through summing pain sites from four body regions. Binomial logistic regression was performed to explore the association between multi-site musculoskeletal pain: (1) discomfort from wearing mandatory equipment and (2) sitting for long periods in fleet vehicles. The prevalence of multi-site musculoskeletal pain at least 1 day per week within the previous 3 months was 41.3%. A statistically significant association between discomfort from wearing mandatory equipment and multi-site musculoskeletal pain was found; duty belt [OR 5.42 (95% CI 4.56-6.43)] as well as body armour [OR 2.69 (95% CI 2.11-3.42)]. Sitting for long periods in fleet vehicles was not significantly associated to multi-site musculoskeletal pain. Multi-site musculoskeletal pain is a considerable problem among Swedish police and modifying mandatory equipment to decrease discomfort is suggested as a potential means of decreasing the musculoskeletal pain experienced by many police officers.

Transportation of radioactive materials: legislative and regulatory information system

Fore, C.S.; Heiskell, M.M.

1980-01-01

The transportation of radioactive materials, as well as hazardous materials in general, has been an issue of ever-increasing concern and an object of numerous regulations and legislative actions worldwide. The Transportation Technology Center of the US Department of Energy's Sandia Laboratories in Albuquerque, New Mexico, is currently involved in developing a national program to assure the safe shipment of radioactive materials. At Oak Ridge National Laboratory (ORNL), Oak Ridge, Tennessee, this overall effort is being supported in a specialized manner. As part of the Logistics Modeling program at ORNL, the Ecological Sciences Information Center has developed comprehensive data bases containing legislative and regulatory actions relevant to the transportation of hazardous materials. The data bases are separated according to status level of the legislation. The Current Legislation Data Base includes all new legislative actions introduced during the present year (1980) or those bills carried over from the previous year's sessions. The second data file, Historical Legislation Data Base, consists of all legislative actions since 1976 that have passed and become public laws, as well as those actions that were unsuccessful and were classified as denied by law. Currently the data bases include state-, local-, and federal, level legislation, with emphasis on the transportation of radioactive materials. Because of their relevance to the transportation issues, actions involving related subject areas such as, disposal and storage of radioactive wastes, moratoriums on power plant construction, and remedial actions studies, special agencies to regulate shipment of radioactive materials, and requirements of advanced notification, permits and escorts are also included in the data bases

Impact of a new mandatory reporting law on reporting and identification of child sexual abuse: A seven year time trend analysis.

Science.gov (United States)

Mathews, Ben; Lee, Xing Ju; Norman, Rosana E

2016-06-01

Child sexual abuse is widespread and difficult to detect. To enhance case identification, many societies have enacted mandatory reporting laws requiring designated professionals, most often police, teachers, doctors and nurses, to report suspected cases to government child welfare agencies. Little research has explored the effects of introducing a reporting law on the number of reports made, and the outcomes of those reports. This study explored the impact of a new legislative mandatory reporting duty for child sexual abuse in the State of Western Australia over seven years. We analyzed data about numbers and outcomes of reports by mandated reporters, for periods before the law (2006-2008) and after the law (2009-2012). Results indicate that the number of reports by mandated reporters of suspected child sexual abuse increased by a factor of 3.7, from an annual mean of 662 in the three year pre-law period to 2448 in the four year post-law period. The increase in the first two post-law years was contextually and statistically significant. Report numbers stabilized in 2010-2012, at one report per 210 children. The number of investigated reports increased threefold, from an annual mean of 451 in the pre-law period to 1363 in the post-law period. Significant decline in the proportion of mandated reports that were investigated in the first two post-law years suggested the new level of reporting and investigative need exceeded what was anticipated. However, a subsequent significant increase restored the pre-law proportion, suggesting systemic adaptive capacity. The number of substantiated investigations doubled, from an annual mean of 160 in the pre-law period to 327 in the post-law period, indicating twice as many sexually abused children were being identified.

Reducing information asymmetry in the power industry: Mandatory and voluntary information disclosure regulations of sulfur dioxide emission

International Nuclear Information System (INIS)

Zhu Xufeng; Zhang Chao

2012-01-01

This paper focuses on the institutional framework for sulfur dioxide emission information disclosure (SDEID) in power industries. The authors argue that mandatory and voluntary SDEID are two complementary regulatory instruments for emission reduction in the power industry. An analytical framework of SDEID with six facets is suggested in this paper to demonstrate relevant legal provisions and regulatory policies of mandatory and voluntary SDEID of power industries in the US. Empirical research shows that mandatory and voluntary SDEID of the power industry have been regulated simultaneously in the US. The foundation of power companies' willingness to disclose emission information voluntarily is the combination of mandatory scientific monitoring with market regulation in the current SDEID system in the US. In comparison, the SDEID of power industries has yet to be widely implemented in developing countries. Finally, the paper provides some implications to developing countries that plan to learn institutional arrangements from developed countries. - Highlights: ► Mandatory and voluntary SDEID are two complementary regulatory instruments. ► An analytical framework is suggested to demonstrate SDEID of power industry in the US. ► Voluntary disclosure can be attributed to scientific monitoring and market regulation. ► We provide implications to developing countries learning from developed countries.

All-terrain vehicle fatalities on paved roads, unpaved roads, and off-road: Evidence for informed roadway safety warnings and legislation.

Science.gov (United States)

Denning, Gerene M; Jennissen, Charles A

2016-05-18

All-terrain vehicles (ATVs) are designed for off-highway use only, and many of their features create increased risk with roadway travel. Over half of all ATV-related fatalities occur on roadways, and nonfatal roadway crashes result in more serious injuries than those off the road. A number of jurisdictions have passed or have considered legislation allowing ATVs on public roadways, sometimes limiting them to those unpaved, arguing that they are safe for ATVs. However, no studies have determined the epidemiology of ATV-related fatalities on different road surface types. The objective of the study was to compare ATV-related deaths on paved versus unpaved roads and to contrast them with off-road fatalities. Retrospective descriptive and multivariable analyses were performed using U.S. Consumer Product Safety Commission fatality data from 1982 through 2012. After 1998, ATV-related deaths increased at twice the rate on paved versus unpaved roads. Still, 42% of all roadway deaths during the study period occurred on unpaved surfaces. States varied considerably, ranging from 18% to 79% of their ATV-related roadway deaths occurring on unpaved roads. Paved road crashes were more likely than those on unpaved surfaces to involve males, adolescents and younger adults, passengers, and collisions with other vehicles. Both the pattern of other vehicles involved in collisions and which vehicle hit the other were different for the 2 road types. Alcohol use was higher, helmet use was lower, and head injuries were more likely in paved versus unpaved roadway crashes. However, head injuries still occurred in 76% of fatalities on unpaved roads. Helmets were associated with lower proportions of head injuries among riders, regardless of road surface type. Relative to off-road crashes, both paved and unpaved roads were more likely to involve collisions with another vehicle. The vast majority of roadway crashes, however, did not involve a traffic collision on either paved or unpaved roads

THE INFLUENCES OF CHANGES IN TAX LEGISLATION

MORAR IOAN DAN

2013-07-01

Full Text Available Taxation is a fairly important field in the relationship between taxpayers and tax authorities, especially given the frequent changes in specific legislation. Legislative changes affect the patrimonial position of the taxpayers, but also their behavior, therefore this phenomenon is important to advise those interested and also to analyze the changes resulting from changes in tax legislation. This paper aims to meaningfully present the latest legislative changes and to analyze their influences on taxpayers and on budget revenues from taxes subject to change. The research methodology is based on comparison and inference, based on previous analyzes for such studies on the tax system. In the literature there are known ways and methods of increasing the tax burden and, based on these variables, in the present paper we will highlight the particular influences on the taxpayer’s , loaded by weight imposed by the official distribution of the tax burden. The implications of legislative changes in tax matters should be sought in the innermost chord of taxpayers and also in the increasingly large and patched pockets of the modern state. In the first place, we will point out the implications on changing tax procedures, in terms of the workload for the taxpayer and the tax collectors. By accurately and relevantly analyzing the influences generated by such changes, the author aims to demonstrate the harmful influences of some changes in terms of discouraging investments and honest labor.

[The ideology of the common good and legislative issues concerning abortion].

Science.gov (United States)

Marques Pereira, B

1984-01-01

This work examines the ideology of the general interest as it is expressed in 2 opposing legislative proposals regarding abortion put forth in Belgium in the early 1980s. The Flemish Liberal proposal deposed in the Senate by Lucienne Herman-Michielsens represents a possible compromise for the Social Christians because it would retain the principle of penal prohibition of all abortions except those considered therapeutic, while the proposal deposed in the Chamber by Leona Detiege calls for decriminalization of voluntary abortions and recognition of the decision-making autonomy of the woman. Legislative reforms express more than agreements of ideologic and political forces; they manifest compromises, negotiations, confrontations, and even insults between social groups and classes. The discourse of general interest is often used to legitimize the demands of specific groups. Herman-Michielsens' proposal would permit abortion only if continuation of the pregnancy posed a grave threat to the life or health of the mother, and only in a hospital by a gynecologist aided by a committee consisting of gynecologists, a specially trained psychologist or psychiatrist, a social nurse, and a jurist. Modalities of control over the sexuality of women would thus be involved, with power exercised through refusal of the right to dispose of their own bodies to women, censure expressed by mandatory committees reviewing each case, and penal sanctions against abortions not deemed therapeutic. The argument in favor of penal sanctions invokes the general interest in the sense of the social order; use of the notion of abortion as an offense against the social order disguises the exercise of social control over sexuality. In the view of this proposal, the dissociation of sexuality and procreation constitutes a peril that must be fought with coercive measures. The proposal is based on an ideological conservatism characterized by a paternalistic attitude toward women and a view of freedom which

Joslin, Jeremy; Mularella, Joshua; Bail, Allison; Wojcik, Susan; Cooney, Derek R

2016-02-01

Provisions of medical direction and clinical services for ultramarathons require specific attention to heat illness. Heat stress can affect athlete performance negatively, and heat accumulation without acclimatization is associated with the development of exertional heat stroke (EHS). In order to potentially mitigate the risk of this safety concern, the Jungle Marathon (Para, Brazil) instituted mandatory rest periods during the first two days of this 7-day, staged, Brazilian ultramarathon. Race records were reviewed retrospectively to determine the number of runners that suffered an emergency medical complication related to heat stress and did not finish (DNF) the race. Review of records included three years before and three years after the institution of these mandatory rest periods. A total of 326 runners competed in the Jungle Marathon during the 2008-2013 period of study. During the pre-intervention years, a total of 46 athletes (21%) DNF the full race with 25 (54.3%) cases attributed to heat-related factors. During the post-intervention years, a total of 26 athletes (24.3%) DNF the full race with four (15.4%) cases attributed to heat-related factors. Mandatory rest stops during extreme running events in hot or tropical environments, like the Jungle Marathon, are likely to improve athlete safety and improve the heat acclimatization process.

[History of psychiatric legislation in Italy].

Stocco, Ester; Dario, Claudia; Piazzi, Gioia; Fiori Nastro, Paolo

2009-01-01

The different models of mental illness which have followed one another in Italian psychiatry have been linked to the history of psychiatric legislation and its various attempts at reform. The first law of the newly United State which unified legislations and former procedures, whose prevalent psychiatric theories were those that referred to degeneration, was the law 36/1904 that set up the asylums. Accordingly psychiatric praxis was focused on social protection and custody, given that the mentally ill was seen as incurable; Fascism added the inmate's obligation to be enrolled in the judicial register. Afterwards numerous attempts to reform the psychiatric legislation were made that eventually gave rise to law 431/1968 which paved the way to territorial psychiatry. Law 180/1978 changed the organization of Italian psychiatry abolishing asylums and the concept of dangerousness, including psychiatry in the National Health Service but adopting an idea of mental illness as simply social unease.

More than 120 countries require or permit the use of International Financial Reporting Standards (‘IFRS’) by publicly listed companies on the basis of higher information quality and accounting comparability from IFRS application. However, the empirical evidence about these presumed benefits are often conflicting and fail to separate between information quality and comparability. In this paper we examine the effect of mandatory IFRS adoption on firms’ information environment. We find that afte...
