It is unclear from Canadian case law what the appropriate legal standards of care and regulation should be in athlete injury cases. This chapter provides an overview of existing legal standards and explores the question of participant liability in sport, especially ice hockey. It reviews the applicability of tort law, including both intentional torts and unintentional torts, and considers the applicability and impact of the notion of ‘volenti non fit injuria’ (or voluntary assumption of risk).

The chapter is based on a review of Canadian case law.

Canadian courts have adopted varying standards whereby it is seemingly easier to prove negligence in certain provinces than others. We discuss the implications of these conflicting jurisdictional standards and the need for clearer and more consistent legal guidelines. Further, we show why appropriate legal standards should extend beyond purely objective and legalistic interpretations to more subjective and sociological factors that place sports violence and sports injury in social context.

Oral health is an integral part of the general health, however, oral health has been given lower priority than other health problems especially among the underprivileged refugee population. Out of total refugees in the world, 70 percent of the refugees belong to Tibet. The purpose of this paper is to assess the dental caries status and treatment needs of Tibetans residing in Shimla, Himachal Pradesh, India and to explore and suggest better oral health care delivery to them.

Tibetans above the age of 12 years were included in this cross-sectional study. American Dental Association Type-3 examination was conducted. Data regarding demography and oral health practices was recorded on a structured format. For recording dental caries, dentition status and treatment need index was used. The data were analyzed using the SPSS statistical software. χ2 test, student t-test, and ANOVA test were used.

A total of 18,831 teeth were examined among which 82 percent were sound, 16.7 percent decayed, 0.7 percent were filled without decay, 0.1 percent filled with decay, 0.03 percent were bridge abutments and 0.15 percent teeth had traumatic injury. The mean DMFT was 7.3 and it was increasing with the age. Mean number of teeth requiring one surface filling, two or more surface filling, pulp therapy, and extraction was 1.27, 0.39, 0.21, and 2.08, respectively.

The study revealed low prevalence of dental caries among Tibetans and dental treatment requirement steadily increased with the advancement of age and was also related to other factors like poverty, education, and their tough life where oral health is given no priority.

In order to succeed in an action under the Equal Pay Act 1970, should the woman and the man be employed by the same employer on like work at the same time or would the woman still be covered by the Act if she were employed on like work in succession to the man? This is the question which had to be solved in Macarthys Ltd v. Smith. Unfortunately it was not. Their Lordships interpreted the relevant section in different ways and since Article 119 of the Treaty of Rome was also subject to different interpretations, the case has been referred to the European Court of Justice.

Environmentally friendly products are finding a place in everyday lives more frequently, like bamboo toothbrushes. However, the authors find no statement from consumer protection centers about their impact on the human well-being or dental health in daily use. Therefore, this study aims to investigate the tribological parameters between tooth, toothpaste and toothbrush laboratory tests with a focus on abrasive wear.

The real-world system was systematically transferred to a laboratory scale, which was implemented to a Schwing-Reib-Verschleiß tribometer tribometer (Optimol Instruments). For an abstraction of the real-world system, as many components of the original tribosystem as possible were retained. In addition, the abstraction was selected so that the method could be transferred to other tribometers. For the evaluation of the test subjects, an optical measurement method was developed to investigate the forms of wear.

Based on eight test series, it is possible to differentiate between the tribological partners by the wear results. With the help of the measurement method, it will be possible to recommend the use of sustainable oral hygiene products for everyone in everyday life in future. According to the findings, the use of low-cost toothbrushes and highly abrasive toothpaste should be avoided. The effects of an aggressive brushing technique cannot be compensated by gentle toothbrushes and toothpastes.

To the best of the authors’ knowledge, this is the first approach to investigate the wear behavior of tooth–toothpaste–toothbrush while substitute the tooth with dental gypsum. The approach is relevant for developing screening tests with high respect to transferability to the real-world application.

Violence against the police represents an ongoing and serious problem in the USA. In 2014, over 48,000 law enforcement officers assaulted while on duty. Although over one in four of these resulted in injury, little is known about the conditions under which injury is likely to occur. The purpose of this paper is to provide an assessment of the individual and situational factors that predict injurious assaults against law enforcement.

Using logistic regression, the current study analyzes data from the 2012 National Incident-Based Reporting System (NIBRS) on all assaults against the police (n=8,987) in order to understand, within a routine activities theoretical framework, how individual-level characteristics (i.e. officer and offender characteristics) and situational influences (i.e. assignment type, activity type, and location) predict the likelihood that an assault will result in injury.

Overall, findings suggest support for a routine activities theory of violence against the police. Initiating an arrest, one-officer vehicle type, and incidents occurring on highways/roads were all more likely to result in injurious assaults against the police. Other predictors of injury include officer and offender demographics as well as the time the incident took place.

This research was unable to control for some factors that may influence the likelihood of injury such as wearing body armor. Additionally, NIBRS data are not nationally representative, which limits the generalizability of the findings.

This is one of the first papers to use national data to examine the individual and situational factors that predict injurious assaults against law enforcement.

The purpose of this study is to obtain the optimal three-dimensional (3D) printing condition through the accuracy evaluation of the protective dental splints (PDSs) produced using 3D printed dental casts under various conditions.

The dental casts of dentiform were made using the conventional method and three digital methods. The three 3D printers used one or two materials for each, and the density of the material was varied to find the appropriate printing condition. PDSs were fabricated by the same method using vacuum former on conventional dental casts, and 3D printed dental casts. PDSs were mounted on a dentiform, and the accuracy was measured according to the criteria.

All of the PDSs fabricated using the traditional method showed the highest accuracy, whereas the PDSs made using 3D printed casts showed accuracies that varied with the type of printer, material characteristics and printing density. Achieving the accuracy required for 3D printed dental casts to be used as protective dental devices made with a vacuum former requires appropriate materials and 3D printing density. The findings of this study can be used when making 3D printed models and individual PDSs through intraoral scanning for patients in whom it is difficult to take impressions using traditional methods.

When a digital device is applied to the fabrication of PDSs, it has the advantage of saving time and materials and preventing damage to teeth and periodontal tissue that may occur during the conventional method.

The purpose is to theorize and empirically estimate the impact of the gendered nature of the offender-victim dyad and crime type on time to arrest.

Predictions regarding the impact of gendered offender-victim dyads and crime type on time to arrest are constructed by extending role congruity theory and tested using data from the FBI's National Incident-Based Reporting System across five crime types using dyadic-based event history methods.

The authors find strong empirical support that role expectations derived from the gender composition of offender-victim dyads and the masculinity of the crime type affect time to clearance.

This research is the first to theorize and empirically test the relative impact of role congruency and the relational nature of the offender-victim dyad in the adjudication process. Furthermore, the research shows that the construction of “normal crime” can be enhanced by applying a gendered and relational approach, based on social psychological theory, which is predictive of crime clearance.

Future research is required to validate the results for crimes where law enforcement has less discretion and are feminine typed.

The results imply that by accounting for the expectations generated by gender roles when applied to offender-victim dyads a casual mechanism is established that better organizes previously inconsistent results with respect to the impact of gender on time to clearance. Thus, the authors' utilization of role congruity theory of gender provides a more consistent explanation for inequalities in time to clearance that may be fruitful for evaluating other steps in the adjudication process.

There is a growing evidence of considering human trafficking as a severe form of violence which usually results in various health outcomes including symptoms of physical health problems. This study aims to examine the magnitude of physical health symptoms during the trafficking period and compare it with that of the period prior to it.

A total of 1,387 trafficking returnees from abroad via three trafficking corridors of Ethiopia were recruited consecutively. Among socio-demographic and other characteristics, data on various physical health symptoms that were experienced during the trafficking period and in the two years prior to trafficking were collected. The proportions of physical health symptoms experienced during the two periods were determined and compared using chi-square test.

Among all participants, 598 (46.79%) of them experienced weight loss during the trafficking period and 106 (8.28%) before the trafficking period. The extra 38.50% which was experienced during the trafficking period was statistically significant (p < 0.0001). Similar significant differences were observed for symptoms such as forgetfulness (p < 0.0001), stomachache (p = 0.0039), gynecological problems (p = 0.041), bone fracture (p < 0.0001), back pain (p < 0.0001), and wound (p < 0.0001); but not significantly different for symptoms such as skin disease (p-value = 0.1944), tooth pain (p-value =0.6587) and sight problem (p-value = 0.1306).

Comparing the frequencies of physical health symptoms before and during the trafficking period among victims of trafficking is relatively a new approach to measure the nexus between Human trafficking and health problems.

The purpose of this paper is to determine the type and severity of domestic violence faced by Indian women. An attempt has also been made to analyze and interpret demographic variations of domestic violence. The authors have highlighted steps taken by several government, community and private organizations on issues of domestic violence.

The analysis of National Family Health Survey (NFHS)-III data (2005) was used for determining the socio-economic factors, which are predictors of domestic violence against spouses and children. Logistic Regression Technique was applied.

Results suggest that increased formal education for women, increase in family wealth, and financial independence may decrease spousal violence. Younger women and those who belong to a nuclear family are more vulnerable to spousal violence.

The research paper only limits its focus on women in India in the age group of 15-49. A cross-country comparison and a longitudinal study would have given better idea on the issue. Besides in India, there are serious issues of concerns of violence against children and elders which have not been part of discussion on this paper.

The paper not only discusses causes of domestic violence but also on its effects on physical and psychological well-being of women and children.

The uniqueness of the study lie in on not only extracting out from NFHS survey-III data, the socio-economic factors which are determinants of domestic violence but also analyzing the politico-religious-cultural factors which play major role on the issue. The authors have also thrown light on consequences of domestic violence.

Many information systems involve data about people. In order reliably to associate data with particular individuals, it is necessary that an effective and efficient identification scheme be established and maintained. There is remarkably little in the information technology literature concerning human identification. Seeks to overcome that deficiency by undertaking a survey of human identity and human identification. Discusses techniques including names, codes, knowledge‐based and token‐based identification, and biometrics. Identifies the key challenge to management as being to devise a scheme which is practicable and economic, and of sufficiently high integrity to address the risks the organization confronts in its dealings with people. Proposes that much greater use be made of schemes which are designed to afford people anonymity, or which enable them to use multiple identities or pseudonyms, while at the same time protecting the organization′s own interest. Describes multi‐purpose and inhabitant registration schemes, and notes the recurrence of proposals to implement and extend them. Identifies public policy issues. Of especial concern is the threat to personal privacy that the general‐purpose use of an inhabitant registrant scheme represents. Speculates that, where such schemes are pursued energetically, the reaction may be strong enough to threaten the social fabric.
