The revised Directive on waste (Directive 2008/98/EC) enteredinto force on 12 December 2008. The purpose of the revised Directiveis to simplify the existing legislative framework for wastein order to encourage the divergence of waste away from landfills,to strengthen legal certainty and minimise burdens on businesses,regulators and stakeholders. This article explores the mainfeatures of the revised Directive and assesses them againstthe European Commissions' intentions in introducing the Directive.In addition, the paper considers the extent to which the revisedDirective promotes successfully (i) reduction of natural resourceuse, (ii) prevention of environmental impacts of waste generation,(iii) life-cycle thinking and; (iv) securing waste prevention.The paper concludes that there is still room for further clarification,particularly in relation to the criteria for by-products andthe new waste management terms ‘end of waste’ and‘preparing for re-use’. Whilst the revised Directivehas weaknesses and limitations it should be considered withinthe context of decision-making. In this way it represents amulti-party, multi-institutional and multi-national compromisewhich should be considered as a progressive step towards improvingthe whole life-cycle of products and resources. Undoubtedly,the revised Directive sets the tone for future legislative developmentsand bolsters the importance of extended producer responsibilityin future waste management measures.  相似文献

One of the four pillars of the anthropological protocol is the estimation of sex. The protocol generally consists of linear metric analysis or visually assessing individual skeletal traits on the skull and pelvis based on an ordinal scale of 1-5, ranging from very masculine to very feminine. The morphologic traits are then some how averaged by the investigator to estimate sex. Some skulls may be misclassified because of apparent morphologic features that appear more or less robust due to size differences among individuals. The question of misclassification may be further exemplified in light of comparisons across populations that may differ not only in cranial robusticity but also in stature and general physique. The purpose of this study is to further examine the effect of size and sex on craniofacial shape among American populations to better understand the allometric foundation of skeletal traits currently used for sex estimation. Three-dimensional coordinates of 16 standard craniofacial landmarks were collected using a Microscribe-3DX digitizer. Data were collected for 118 American White and Black males and females from the W.M. Bass Donated Collection and the Forensic Data Bank. The MANCOVA procedure tested shape differences as a function of sex and size. Sex had a significant influence on shape for both American Whites (F = 2.90; d.f. = 19, 39; p > F = 0.0024) and Blacks (F = 2.81; d.f. = 19, 37; p > F = 0.0035), whereas size did not have a significant influence on shape in either Whites (F = 1.69; d.f. = 19, 39; p > F = 0.08) or Blacks (F = 1.09; d.f. = 19, 37; p > F = 0.40). Therefore, for each sex, individuals of various sizes were statistically the same shape. In other words, while significant differences were present between the size of males and females (males on average were larger), there was no size effect beyond that accounted for by sex differences in size. Moreover, the consistency between American groups is interesting as it suggests that population differences in sexual dimorphism may result more from human variation in size than allometric variation in craniofacial morphology.  相似文献

ABSTRACT

Syrian refugees are causing upheavals in Jordan’s economy and education. Unemployment of Jordan’s native youth is 29.9% without the addition of unemployed refugees further threatening the stability of the country. The cost of educating, sheltering, feeding and integrating them into the cities with resulting school congestion creates resentment in citizens paying 60% of their national budget for refugees. To alleviate educational pressures alone, Jordan solicited funding from the European Union, United Kingdom, Germany, United States and Norway. Together, they pledged 81.5 million in May 2016 to expand education for Jordan’s refugee children. From the refugees’ perspective, all face similar challenges in gaining access to classrooms, adapting to the culture taught in the schools and catching up academically as they try to prepare for and seek employment to survive. Jordan’s government has implemented two 5-year educational reorganization programmes Educational Reform for Knowledge Economy (ERfKE) I, II that are in many cases unknowingly shifting instruction from idealism to pragmatism. This philosophical movement towards pragmatism is less expensive and more effective for future employment of all students in contrast to the existing idealistic system. Jordan’s transitioning changes in educational philosophies and programmes provide visions for Jordan’s future. Their educational adaptations provide suggestions for other refugee host countries.  相似文献

Objectives

Fear of crime may develop in response to crime specifically (the narrow pathway) or may be a projection of broader threats (the broad pathway). New approaches are needed to examine how crime and threat, independently and in combination, influence people’s fear. To address this need, we created, evaluated, and validated an image set that varied across the dimensions of threat and crime.

Method

We used a 2 (Threat: high vs. low) × 2 (Crime: high vs. low) within-subjects factorial design. In three studies, participants (N = 24, 29, and 176, respectively) gave threat, crime, and fear ratings towards images. Participants also completed two traditional fear of crime measures and a measure of anxiety. Two evaluation studies explored the suitability of 178 images to produce a final set of 80 images (20 in each of the four categories). We validated this final set of 80 images in a third study.

Results

The validated Crime and Threat Image Set (CaTIS) contains 78 images across four categories: threat-and-crime (high-crime, high-threat), threat-only (low-crime, high-threat), crime-only (high-crime, low-threat), and neutral (low-crime, low-threat). There were significant main effects of threat and crime, and an interaction between Threat × Crime, on participants’ fear ratings. Participants’ own ratings of threat—but not crime—had a strong relationship with their fear ratings.

Conclusions

Threat had a stronger influence on participants’ fear ratings than crime. Thus, what is typically referred to as fear of crime may reflect broader fear. Further research with the CaTIS could explore the expression of this fear.

The purpose of this study was to evaluate child abuse prevention campaign materials. Using a randomized posttest design, 600 parents from an online research panel were recruited and surveyed. Multiple regression results indicate that exposure to the campaign materials had a significant relationship with four of the five domains (effects of child maltreatment, the appropriateness of harsh parenting, the physical dangers and needs unique to childhood, and the power to prevent child maltreatment). These results have implications for the child abuse prevention practitioners who seek to design and distribute effective campaign materials.  相似文献

It is common for researchers using animal or human remains for scientific study to freeze samples prior to use. However, effects of freezing on bone macro‐ or microstructure are relatively unknown. The research objective of this study was to determine whether freezing could potentially bias experimental results by analyzing changes in bone mineral density (BMD) with the freezing of remains over time. Eight fetal pigs were scanned to determine their initial BMD before freezing. Three piglets underwent a freeze‐thaw cycle to assess the effects of the freezing process. Four piglets were frozen and scanned weekly for 20 weeks to assess freezing over time. The overall average between the fresh initial scan and final frozen scan was significantly different (p < 0.001). Per contra, the final thawed BMD scans did not differ from the initial fresh scan (p = 0.418). Thus, completely thawed remains are recommended for experimental studies.  相似文献

Scholars of public health identify globalization as a major cause of obesity. Free markets are blamed for spreading high calorie, nutrient-poor diets, and sedentary lifestyles across the globe. Global trade and investment agreements apparently curtail government action in the interest of public health. Globalization is also blamed for raising income inequality and social insecurities, which contribute to “obesogenic” environments. Contrary to recent empirical studies, this study demonstrates that globalization and several component parts, such as trade openness, FDI flows, and an index of economic freedom, reduce weight gain and obesity among children and youth, the most likely age cohort to be affected by the past three decades of globalization and attendant lifestyle changes. The results suggest strongly that local-level factors possibly matter much more than do global-level factors for explaining why some people remain thin and others put on weight. The proposition that globalization is homogenizing cultures across the globe in terms of diets and lifestyles is possibly exaggerated. The results support the proposition that globalized countries prioritize health because of the importance of labor productivity and human capital due to heightened market competition, ceteris paribus, even if rising incomes might drive high consumption.  相似文献

A large proportion of perinatally HIV-infected (PHIV) children are becoming adolescents and exploring their sexuality. This study explored the prevalence of sexual behaviors (kissing, touching, engaging in oral sex, or having vaginal/anal intercourse) in a sample of predominantly ethnic minority youths (N = 339; 54.1% Black and 30.4% Latino; 51% female; ages 9–16) perinatally exposed to HIV (61% HIV+). Using logistic regression, we tested the association between sexual behavior and HIV status, demographic characteristics, and peer influences regarding sexual behavior. PHIV youth were less likely to be sexually active. Among sexually active youth, PHIV youth were more likely to engage in touching behavior than HIV-negative youth and were less likely to engage in penetrative sex. Youths reporting that a greater number of their peers believed that sexually active boys were “cool” or “popular” were more likely to report sexual behavior. The association between sexual behavior and peers believing sexually active girls were “cool” or “popular” varied by age, gender, and HIV status. Furthermore, friends’ sexual activity was associated with sexual intercourse. Prevention programs should strengthen messages addressing peer norms regarding sexuality, as well as address specific issues related to adolescent HIV.

More than 30 years ago research found that alliteration is a factor in assortative mating (i.e., marriages). Alliterative matches were even more frequent when using nicknames than when using given names. Subsequently, researchers have confirmed the higher than chance occurrence of alliterative matches for given names. But nicknames have not been examined over the past 30 years. The present research finds support for three hypotheses. As predicted, nicknames are more associated with alliterative matches than are given names. Implications for practice are discussed.  相似文献

Classification of violent behavior, including dismemberment and mutilation, has become increasingly more significant. This study uses a data-driven classification system based upon knowledge drawn from the pertinent literature, and examination of cases of offenders who have dismembered or mutilated their victims. The latter were extracted from the Serial Killer Database, as well as media sources, and assessed for characteristics of the perpetrators and victim(s). An informational form was developed and used to establish quantitative parameters and objectively extract pertinent information that could be used for comparison and pattern analysis. Motives and styles, as well as the organized/disorganized dichotomy for murder and dismemberment/mutilation, were examined for each case. The majority of cases demonstrated defensive styles (60%), with the second most common being offensive styles (26%), which differs from previous studies that do not exclude older cases. Additionally, 68% of cases reflected organized patterns for both murder and the acts of dismemberment or mutilation. The results support a data-driven classification system that may serve as a foundational model for the investigation of specific motives of this type of deviant behavior in future research.  相似文献
