The nurse is caring for a client with seasonal affective disorder (SAD). Which type of therapy is considered a first-line treatm

taurus [48]

According to the research, Light therapy is considered a first-line treatment for a client with seasonal affective disorder (SAD).

<h3>What is light therapy?</h3>

It is the application of sunlight for therapeutic and preventive purposes, it helps to increase body temperature (improving metabolic and trophic processes).

It is used as treatment for clients with SAD to regulate the circadian cycle and biological processes, such as melatonin secretion.

Therefore, we can conclude that according to the research, Light therapy is considered a first-line treatment for a client with seasonal affective disorder (SAD).

Compare the two theories of color perception are they completely different

galben [10]

We do not see the world in black and white; neither do we see it as two-dimensional (2-D) or flat (just height and width, no depth). Let’s look at how color vision works and how we perceive three dimensions (height, width, and depth).
Color Vision
Normal-sighted individuals have three different types of cones that mediate color vision. Each of these cone types is maximally sensitive to a slightly different wavelength of light. According to the trichromatic theory of color vision, shown in Figure 1, all colors in the spectrum can be produced by combining red, green, and blue. The three types of cones are each receptive to one of the colors.
The trichromatic theory of color vision is not the only theory—another major theory of color vision is known as the opponent-process theory. According to this theory, color is coded in opponent pairs: black-white, yellow-blue, and green-red. The basic idea is that some cells of the visual system are excited by one of the opponent colors and inhibited by the other. So, a cell that was excited by wavelengths associated with green would be inhibited by wavelengths associated with red, and vice versa. One of the implications of opponent processing is that we do not experience greenish-reds or yellowish-blues as colors. Another implication is that this leads to the experience of negative afterimages. An afterimage describes the continuation of a visual sensation after removal of the stimulus. For example, when you stare briefly at the sun and then look away from it, you may still perceive a spot of light although the stimulus (the sun) has been removed. When color is involved in the stimulus, the color pairings identified in the opponent-process theory lead to a negative afterimage. You can test this concept using the flag in Figure 2.
But these two theories—the trichromatic theory of color vision and the opponent-process theory—are not mutually exclusive. Research has shown that they just apply to different levels of the nervous system. For visual processing on the retina, trichromatic theory applies: the cones are responsive to three different wavelengths that represent red, blue, and green. But once the signal moves past the retina on its way to the brain, the cells respond in a way consistent with opponent-process theory (Land, 1959; Kaiser, 1997).
Depth Perception
Our ability to perceive spatial relationships in three-dimensional (3-D) space is known as depth perception. With depth perception, we can describe things as being in front, behind, above, below, or to the side of other things.

Our world is three-dimensional, so it makes sense that our mental representation of the world has three-dimensional properties. We use a variety of cues in a visual scene to establish our sense of depth. Some of these are binocular cues, which means that they rely on the use of both eyes. One example of a binocular depth cue is binocular disparity, the slightly different view of the world that each of our eyes receives.
A 3-D movie works on the same principle: the special glasses you wear allow the two slightly different images projected onto the screen to be seen separately by your left and your right eye.
Although we rely on binocular cues to experience depth in our 3-D world, we can also perceive depth in 2-D arrays. Think about all the paintings and photographs you have seen. Generally, you pick up on depth in these images even though the visual stimulus is 2-D. When we do this, we are relying on a number of monocular cues, or cues that require only one eye. If you think you can’t see depth with one eye, note that you don’t bump into things when using only one eye while walking—and, in fact, we have more monocular cues than binocular cues.
An example of a monocular cue would be what is known as linear perspective. Linear perspective refers to the fact that we perceive depth when we see two parallel lines that seem to converge in an image (Figure 3).
Vision is not an encapsulated system. It interacts with and depends on other sensory modalities. For example, when you move your head in one direction, your eyes reflexively move in the opposite direction to compensate, allowing you to maintain your gaze on the object that you are looking at. This reflex is called the vestibulo-ocular reflex. It is achieved by integrating information from both the visual and the vestibular system (which knows about body motion and position). You can experience this compensation quite simply.
Finally, vision is also often implicated in a blending-of-sensations phenomenon known as synesthesia.

Give an example of a 2 x 2 matrix game with exactly three nash equilibria in pure strategies. Explain.

weeeeeb [17]

Answer:

A Nash equilibrium is a profile of strategies (s1,s2) such that the strategies are best responses to each other, i.e., no player can do strictly better by deviating. This helps us to find the (pure strategy) Nash equilibria.

To start, we find the best response for player 1 for each of the strategies player 2 can play. I will demonstrate this by underlining the best responses:

ABCA1–,10,101–,−10B10–––,01,11,10C−10,110–––,11,1

Player 1 is the row player, player 2 is the column player. If 2 plays column A, then player 1's best response is to play either row A or C, which gives him 1 rather than 0 as payoff. Similarly, the best response to column B is row A, and to column C it is row B.

Now we do the same for player 2 by underlining the best responses of the column player:

ABCA1–,1–0,10–––1–,−10B10–––,01,11,10–––C−10,1–10–––,11,1

So, if player 1 plays row A then player 2 best responds either with column A or column C, giving him 1 rather than 0. We also find the best responses for row B and C.

Now a pure strategy Nash equilibrium is a cell where both payoffs are underlined, i.e., where both strategies are best responses to each other. In the example, the unique pure strategy equilibrium is (A,A). (There may also be mixed strategy equilibria.) In all other cells, at least one player has an incentive to deviate (because it gives him a higher payoff).

EDIT: How to compute mixed strategy equilibria in discrete games?

In a mixed Nash strategy equilibrium, each of the players must be indifferent between any of the pure strategies played with positive probability. If this were not the case, then there is a profitable deviation (play the pure strategy with higher payoff with higher probability).

Consider player 2. He plays column A with probability p, B with probability q, and C with probability 1−p−q. We need to find p,q such that player 1 is indifferent between his pure strategies A,B,C. He is indifferent between row A (left hand side) and row B (right hand side) if p,q are such that

p+10q−10(1−q−p)=q+10(1−p−q).

He is indifferent between B and C if

q+10(1−p−q)=p+q+1−q−p=1.

You just have to solve the first condition for q as function of p, substitute q in the second condition and you have p. Inserting p again in the first gives you q.

Now we do the same with strategies for player 1 such that player 2 is indifferent. Player 1 plays A with probability x, B with probability y and C with probability 1−x−y. The two conditions that follow are

1x+10y−10(1−x−y)=x+10(1−x−y)x+10(1−x−y)=1

Solve this again to find x,y. This is a mixed-strategy equilibrium, because neither player has a profitable deviation. Remember, we constructed the profile (x,y;p,q) such that the other player is indifferent between his pure strategies. So, no matter how the other player unilaterally deviates, his expected payoff will be identical to that in equilibrium (x,y;p,q). In general, depending on the game and solutions x,y,p,q, there may be infinitely many mixed Nash equilibria, or none. The more pure strategies there are, the more tedious it is to compute mixed strategy equilibria, since we solve for N−1 variables for each player (N being the number of pure strategies of the other player).

Moreover, to find all equilibria, if there are more than 2 actions for a player, then every possible combination of actions has to be checked. Here, a player has 3 actions, and a mixed strategy equilibrium could entail mixing over all three or just any two of them. Since such a player would not have to be indifferent regarding the strategy played with probability 0, the equations you have to set up are different. In summary, manually checking for all possible mixed strategy equilibria if at least one player has more than two actions can require a lot of effort.

Whether someone with a diathesis develops the disorder is determined by

stepan [7]

Answer:

The Diathesis-Stress Model explains that psychological disorders derive from the combination of a predisposition to vulnerability or diathesis, as an innate factor, together with experiences of stress as an acquired factor. Therefore, innate factors and acquired factors are needed to develop certain disorder.

Explanation:

From the perspective of the diathesis-stress model, a disorder is the result of the interaction between a genetic predisposition or vulnerability (diathesis), with external factors or personal experiences (stress). This model is used to explain the development of mental disorders with a clear genetic basis, such as schizophrenia, bipolar disorder, etc. The appearance of the disorder will depend on the combination of both factors. The more genetic predisposition you are, the more likely you are to develop these low-stress diseases. And on the contrary, a low predisposition protects us from suffering a mental disorder, even if different stressors occur in our life.
