Activity 8-9: Evaluate an acceptable use policy. Learn whether the organization where you work or attend school has an acceptable computer use policy for employees or students. Make a list of activities that are permitted and those that are not permitted. Identify on your list those activities that are illegal and those that are not permitted according to organizational policy. Compare your organization’s computer use policy with the University of Oregon’s policy referenced in the chapter. Describe

In this paper‚ “VTA CRF neurons mediate the aversive effects of nicotine withdrawal and promote intake escalation” describes how the multiple researchers‚ such a Grieder‚ Herman...George‚ hypothesized that drug addiction is driven by two mechanisms. One of the mechanisms is the Ventral tegmental area (VTA)‚ which is part of the brain that is rich in dopamine and serotonin neurotransmitter and is part of the two major reward pathway. The other mechanism is Corticotrophin-releasing hormone (CRF)‚ which

the connections between neurons in the brain‚ gain insight into the regulation of appetite and metabolism. The ARC and VMH has long been thought of as satiety centers. Studies that investigate the role of the arcuate nucleus in the hypothalamus‚ in regulating appetite and metabolism‚ have targeted two chemically identified neuronal types within the ARC: anorexigenic pro-opiomelanocortin (POMC) neurons and orexigenic neuropeptide Y (NPY)/agouti-related peptide (AgRP) neurons. The melanocortin α-melanocyte

Polarization of the neuron’s membrane: cell membrane is surrounded by neurons as other cell has a membrane. If a nerve cell is not stimulated‚ the membrane is known to be polarized. For a neuron to be polarized‚ it is by maintaining excess of sodium ions on the outside of the cell and excess potassium ions on the inner part of the cell. A volume of sodium ions and potassium ions usually leaks through its channel but the sodium ions and potassium ions pumps on the membrane that restores the (k+) back

University Dr. David Martin Graphic Organizers and Writing 2 The Effect of Graphic Organizers on Students’ Writing Abstract The purpose of this action research project was to study the effects of graphic organizers‚ specifically a concept map‚ on students’ writing. Our school believes that writing is the key to success‚ so writing instruction is a priority. I was particularly interested in investigating students’ writing through graphic organizers with personal narrative writing prompts given in the

Ecotourism Ecotourism places a value on the health of the local people/tribes etc‚ animals/wildlife and environment and rather than aiming to earn a very high profit at all costs‚ it aims to earn a profit while respecting local people/tribes‚ animals/wildlife and nature as a whole allowing them to benefit in some way from the endeavor. Good ecotourism companies make conscious choices in every aspect of their business. For instance‚ they recycle products and choose biodegradable materials whenever
