What is the average amount that a psychologist charges per hour?
It varies, but can range from 100 to 180 dollars. The median is usually close to 130.
How can you file extortion charges against someone on behalf of someone else in California?
You call the local FBI office. Its a misunderstood crime and only filed at the FBI. Local police don't understand it. Its a federal crime
All users should be alert and report what?
Users of credit cards should be alert and report unauthorized activity that occurs on their account. They should also make sure the charges are accurate and in the right amount.
Internet Addiction information?
Internet addiction is described as an impulse control disorder which does not involve use of an intoxicating drug and is very similar to pathological gambling. * Preoccupation with the Internet. (Thoughts about previous on-line activity or anticipation of the next on-line session.) * Use of the Internet in increasing amounts of time in order to achieve satisfaction. * Repeated, unsuccessful efforts to control, cut back, or stop Internet use. * Feelings of restlessness, moodiness, depression or irritability when attempting to cut down use of the Internet. * On-line longer than originally intended. * Jeopardized or risked loss of significant relationships, job, educational or career opportunities because of Internet use. * Lies to family members, therapist, or others to conceal the extent of involvement with the Internet. * Use of the Internet as a way to escape from problems or to relieve a dysphoric mood. (e.g., feelings of hopelessness, guilt, anxiety, depression.) Internet addiction results in personal, family, academic, financial and occupational problems that are characteristic of other addictions. Impairment of real life relationships are disrupted as a result of excessive use of the internet. Internet addicts spend more time in solitary seclusion and spend less time with real people in their lives. Arguments may result due to the volume of time spent on-line. Internet addicts may attempt to conceal the amount of time spent on-line, which results in distrust and the disturbance of quality in once stable relationships. Financial problems may occur due to the significant amount of time spent on-line and the service provider charges. Common financial issues are large bills for use of some services, the telephone connection charges and telephone bills for calls made to ?friends̠in chat rooms. Other financial charges may include a connection with compulsive spending/shopping. Internet addicts may choose to shop on-line and credit card charges for purchases may become high. Also, a connection with gambling exists with the availability of on-line casinos. Some internet users may develop an emotional attachment to on-line friends and activities they create on their computer screens. Internet users may enjoy aspects of the internet that allow them to meet, socialize and exchange ideas through the use of chat rooms or "virtual communities". These communities allow the person the means to escape from reality and seek out means to fulfill unmet emotional and psychological needs, which are more intimate and less threatening than real life relationships. Some Internet addicts may also create on-line personas where they are able to alter their identities and pretend to be someone other than themselves.The highest risk for creation of a secret life are those who suffer from low self esteem, feelings of inadequacy, and fear of disapproval from others. Such negative self concepts lead to clinical problems of depression. There is help for Internet Addiction. The Illinois Institute for Addiction Recovery at Proctor Hospital provides assessment and treatment services for the Internet addict. Counselors trained in the identification and treatment of Internet addiction provide professional assessments to determine if addiction to the Internet exists and placement into a level of care for treatment.

Multitude of bill collectors calling for other people and when you tell them that no one lives here by that name they continue to call what can you do?
The Fair Debt Collection Practices Act (FDCPA) sets rules for bill collectors working for a collection agency (not a collector working for the creditor, many states have laws for all collectors). One of the rules is that they can not call you at work, harassing you, use inappropriate language, lying, adding unauthorized charges and many other practices. Under the FDCPA, you have the right to demand that the collection agency stop contacting you, except to tell you that collection efforts have ended or that the creditor or collection agency will sue you. You must put it in writing. Some thing happened to me. Certified letter telling them to stop worked like a charm.
Do positive charges tend to move from points of high potential to low potential?
yes
What is it called when positive and negative charges have a potential difference?
Voltage.
How does nerve fiber become depolarized?
A nerve fiber becomes polarized when the resting potential of the membrane changes. It starts out with an unequal distribution of charges- the outside is more positive and the inside is less positive. (Sodium (Na+) is in a higher concentration on the outside of the membrane and Potassium (K+) is in a lower concentration on the inside of the membrane.) A stimulus changes the gradient- when more Na+ flows in, the resting potential changes and polarization occurs, allowing for an action potential to be propagated down the axon.
What is a difference in electric charge called?
The chemical gradient refers to the imbalance of substances across the membrane. The Electrical Gradient refers to the difference of charges between substances on different sides of the Membrane. The Electrochemical Gradient refers to the combination of the previous two gradients. The short answer is MEMBRANE POTENTIAL.
What substances plays a mojor role in generating the membrane potential of a neuron?
Well, for starters, membrane potential is a separation of charges across the membrane. So i think what you mean is "generating the action potential in a neuron". So in that case The substance that plays a major role in generating an action potential is Sodium (Na+). However, if you really mean membrane potential, there is only two substances associated with that and those are sodium (Na+) and potassium (K+).However, in truth, the generation of an action potential depends on the ligand and its receptor.
Circle the letter of the choice that describes an action potential?
a. Reversal of charges due to the flow of positive ions into a neuron
Why electric potential is defined on positive charge?
That's just in convention, in line with other electric convention. It is common to use positive charges as a standard; for example, a current is usually defined as a movement of positive charges. If the actual charges happen to be negative (for example, electrons), the "conventional current" simply flows in the direction opposite to the flow of electrons.
Do positive objects contain only positive charges?
No. A positive ion merely has more positive charges (protons) than negative charges (electrons).
What influences the movement of ions and molecules across cell membranes?
A membrane potential is basically the difference between the inside and outside of the cell. Ions are charged, and so will change the membrane potential (the difference between charges on the inside and outside) when they move. Please see the related link below which includes a diagram of how ions affect membrane potential.
Why is the potential energy of two like charges positive and two unlike charges negative?
This is a way of saying that two like charges repel each other and unlike charges attract. Remember that systems tend to 'seek' the lowest energy state possible.
What is the resting potential and how is it created and maintained?
The resting potential is the voltage inside the neuron cell membrane of about -70 mV (negative 70 millivolts). This electrical potential (separation of charges) is made possible by an imbalance in sodium (positive), potassium (positive), and chloride (negative) ions on each side of the neural membrane. In the case of the resting potential, the surplus of chloride ions and relative deficiency of sodium/potassium ions within the neuron, relative to the outside of the neuron, give a charge difference of 70 millivolts, making the inside of the neuron more negative than the outside.There are ion channels that open and close based on voltages and other factors that are embedded in the neuron's cell membrane. When triggered by a nerve impulse, they open to allow for positive ions to stream into the nerve, which depolarizes it to generate the "signal".After the signal passes, the neuron resets itself by opening ion channels that pump positive ions back out of the neuron, and pump negative ions back in, in order to readjust to the resting potential again.
What is the importance and function of cytosol to the brain?
Cytosol is the fluid found inside cells and is the medium where cellular metabolism takes place. It has a slightly different composition to the fluid found outsides cells (extracellular fluid). In neurons, this difference in fluid composition is critical for cell signaling because it creates an electrochemical potential gradient across the cell membrane. When ions flux in and out of the cell (driven by chemical gradients and 'ion pumps') their charge alters the electrical potential difference across the cell membrane (i.e., think of the membrane as an insulator separating positive and negative charges). If enough positive charge enters a neuron then it will fire (release it's neurotransmitters).
