Chapter 4 The Energy Inherent in Our Waste

Chapter 4

From newspapers to hot dogs, all objects have an inherent amount of energy—their “caloric value.” Simply put, caloric value is the amount of energy that is released when a particular thing is burned. Some objects burn at a positive caloric value, including candles, cigarettes, or basically anything that will continue to burn after you put a lighter to it to get it going. This can easily be calculated in a laboratory by measuring the amount of heat that the object releases per gram and subtracting the amount of energy that was used to get the burn going. Objects with a negative caloric value, on the other hand, consume more energy than they produce in the process of burning.

Calories from items with a positive caloric value are exactly the same type that we try to avoid when we go on our annual New Year’s diet. In other words, if you took sugary, buttery, oil-drenched, icing- and sprinkle-topped doughnuts (yum), they would burn much better (giving you more calories) than things like asparagus, celery, apples, and other foods with a negative caloric value.

6. Brief psychodynamic psychotherapy in adolescent depression: two case studies

Gillian Miles Karnac Books ePub

Stelios Christogiorgos, Eleni Stavrou, Marie-Ange Widdershoven-Zervaki, & John Tsiantis

Depression is thought to affect up to 20% of adolescents (Lewinsohn et al., 1999). This is not surprising as the adolescent stage of growth and development is beset with emotional vicissitudes. The inner turmoil of adolescence may be accompanied by intense affective reactions, considerable moodi-ness, feelings of depression, and fleeting suicidal wishes; sometimes this stage cannot be managed without serious disruptions such as clinical depression. Moreover, dealing with any type of loss can be very difficult for the adolescent and may result in depressive feelings and suicidal preoccupations, which obviously contain a plea for help.

Given the serious nature of adolescent depression it is necessary that the treatment is provided promptly and performed by skilful therapists, but one challenge facing mental health services is the high rate of depressed adolescents who do not receive any help—up to two-thirds in one epidemiological study (Rey, Sawyer, Clark, & Baghurs, 2001).

15. Active Directory

Robbie Allen O'Reilly Media ePub

Active Directory is an LDAP-based directory that supports the LDAP v3 specification defined in RFC 2251. In this chapter, I'm going to cover some of the most common tasks that you'll need to do to support an Active Directory infrastructure. However, Active Directory is a complex intermixed set of technologies that cannot be covered comprehensively in a single chapter. If you want more information after finishing this chapter, read Active Directory (O'Reilly) to get a thorough understanding of Active Directory's capabilities or Active Directory Cookbook (O'Reilly) for more examples, scripts, and tips.

A forest is a logical structure that is a collection of domains, plus the configuration and schema naming contexts, and application partitions. Forests are considered the primary security boundary in Active Directory. By that I mean, if you need to definitively restrict access to a domain to block access by administrators from other domains, you need to implement a separate forest (and subsequently a domain in that forest), instead of using a domain within a given forest. This is due to the transitive trust relationship between all domains in a forest and the extensive permissions that members of the Domain Admins group have. Unlike domains and trusts, a forest is not represented by a container or any other type of object in Active Directory. At a minimum, a forest consists of three naming contexts: the forest root domain, the Configuration Naming Context (NC), and the Schema NC. The Partitions container in the Configuration NC lists partitions that are associated with a forest. Here are the types of partitions that can be part of a forest:
