What is 'sexting', and what does it mean to the current enforcement of child Pornography laws Are minors putting themselves at risk for a lifetime of hell - Essay Example engaging in harmful activities via these modes of communication (Mitchell, & Finkelhor, 2011; Mitchell, Finkelhor, Jones, & Wolak, 2012; Wolak & Finkelhor, 2011). These harmful behaviors are cyberbullying, public posting of sexual images, and soliciting for sex online. Even though the legal definition of the term "sexting" vary across jurisdictions, most state laws focus on images relayed through mobile telephony. However, images are also transmitted through computers, web cameras, and digital cameras among other gadgets (Sacco et al., 2010). Current studies apply broader definitions of sexting, which defines it as the sending and/or receiving of sexually suggestive images or messages by mobile phones, in measuring the prevalence of sexting behaviors among the youth (Mitchell et al., 2012). The youth have extensive access to modern communication technologies, with a reported 25% of them owning mobile phones (Lenhart, 2009). This ease of access enables them to stay in regular contact with parents and friends. Consequent to this ease of access and use, sending and receiving text messages via mobile telephony has become easy and popular, especially among adolescents. A recent study estimates that the youth send and receive approximately 3,000 text messages monthly. In addition, many mobile phones also allow users to send pictures and video. Although there are many positive attributes of mobile telephony such as the ability to instantly connect, communicate, and share, it also has several potential problems, including â€Å"sexting.† The different definitions of sexting have resulted in conflicting findings by researchers on the actual prevalence of sexting among the youth. For example, the National Campaign to Prevent Teen and Unplanned Pregnancy and CosmoGirl.com conducted a study to examine the prevalence of teen and young adult sexting behaviors in 2008. In this study (Sex and Tech) sexting was defined as the relaying of nude or semi-nude photos or videos. The

Network planning for my Logistics class - Essay Example The decisions made on the logistics network are usually framed to act as a trade-off between the fixed costs of a warehouse and the costs of transporting the goods. This means that, if the network has a few warehouses, then there is a reduction of fixed costs although it raises the transportation costs. Adding more warehouses on the network reduces the transportation costs and increasing the fixed costs. There are two different factors which one must consider when designing a network design. The first factor which a logistician must consider most is the distance. Adding more warehouses in a network decreases the number of kilometers travelled because the distance from the supplier to the warehouse and then to the customer is minimized. Moreover, the most expensive part in the logistics is the movement of goods from the warehouse to the end user since the load shipped is always divided into different quantities. The more the warehouses on the design network the fewer the kilometers between the customer and the stores. This paper includes the second factor which is to optimally solve the network design problems whereby there is the inclusion of inventory cost. Ballou (2001) acknowledges the importance of the inventory costs inclusion over the fixed costs of warehousing and also the costs of the transportation. Ballou (2001) also explains that the absence of the inventory costs in network design is caused by the mixed integer in the linear programming, of which is a requirement to have the cost relationships to be linear. Unfortunately, in the real world, the relationships between the inventory and the number of warehouses are not linear. Using the approach of including the inventory costs motivates one to treat the relationship between the inventory and the number of warehouses as a function which is discrete. This is the reason of proposing the model that may be used by different firms through the inclusion of inventory in the
