One of the most significant and effective criteria in the process of cutting dimensional rocks using the gang saw is the maximum energy consumption rate of the machine, and its accurate prediction and estimation can help designers and owners of this industry to achieve an optimal and economic process. In the present research work, it is attempted to study and provide models for predicting the m...
The U.S. has the highest rate of firearm-related deaths when compared to other industrialized countries. Violence particularly affects lowincome, urban neighborhoods in cities like Chicago, which saw a 40% increase in firearm violence from 2014 to 2015 to more than 3,000 shooting victims. While recent studies have found that urban, gang-involved individuals curate a unique and complex communica...
The 1980’s saw an increase in youth gang violence and the rise of the crack cocaine epidemic. The public linked these two developments, often with implications of cause and effect. Conventional wisdom, however, is not always reliable. Viewed through the lens of public perception rather than that of scientific knowledge, the relationships among youth gangs, drugs, and violence are more often tal...
Four methods of converting low-grade yellow-poplar lumber into highgrade furniture core material (lumber core) were compared. High-grade core material is used in tops, shelves, doors, and drawer fronts and only minor defects are allowed. Three gang-rip first and the conventional crosscut-first manufacturing sequences were evaluated in combination with 1 Common, 2A Common, and 2B Common lumber. ...
Gangs have played a significant role in Chicago’s social and political history, and continue to impact the city today, as gang violence rates continue to grow despite drops in overall crime[13]. In this paper, we explore the dynamics of gang involvement between at-risk individuals, gang members, and reformed (temporarily removed) gang members. We focus on the effect that reformed gang members h...
OBJECTIVES To examine the prevalence of gang involvement, the risk and protective factors associated with gang involvement, and the association between gang involvement and exposure to multiple risk and protective factors among school-aged youth in Trinidad and Tobago. METHODS A survey instrument was administered to 2 206 students enrolled in 22 high-risk, urban public schools, from March-Jun...
BACKGROUND Gang violence accounted for 20% of homicides in large cities from 2002 to 2006. Preventing gang affiliation (ie, youth who either desire or have gang membership) might reduce subsequent gang activity. Previous research has focused on identifying risk factors for gang affiliation; however, little information is available on protective factors. AIM To identify risk and protective fac...
The prevalence of Clonorchis sinensis metacercariae (CsMc) was examined in freshwater fish from the water systems of Seomjin-gang (River), the Republic of Korea. Total 1,604 fish from 7 local sites of Seomjin-gang were examined by artificial digestion methods. The metacercariae of C. sinensis were detected in 102 (39.8%) out of 256 fish (14 species) from the upper reaches of Seomjin-gang, i.e.,...
This article discerns the role that Mexican American gang members play in drug markets, and the relationship between gang members'drug use and drug selling in South Texas. A four-part typology based on the two dimensions of gang type and gang member emerged from this qualitative analysis of 160 male gang members: Homeboys, Hustlers, Slangers, and Ballers. Major findings include the following: (...
BACKGROUND Three different explanations have been given for the observation that adolescent gang members report more delinquent behaviour than their counterparts who do not affiliate with gangs: a) adolescents who commit more crimes join gangs (selection hypothesis); b) gang membership facilitates deviant behaviour (facilitation hypothesis); c) selection and facilitation work interactively (enh...
