Professor lyon decided to study food preferences of u.s. college students, so he asked his students to volunteer to participate in a lengthy survey. professor lyon's survey results are probably invalid because he did not use: an operational definition. random selection. a valid hypothesis. independent and dependent variables.

Answers

Answer 1
I believe it’s random selection. Because the students had to volunteer to participate, only those who are passionate about the topic would be included in the data, leading to non response bias. Therefore, there needs to be a more random way to select he students to participate.

Which branch of government may veto laws ?

Answers

The Executive Branch can veto laws. The president is in the executive branch and he can veto laws passed by Congress

Final answer:

The executive branch of government has the power to veto laws, but Congress can override the veto with a two-thirds majority vote.

Explanation:

The executive branch of government has the power to veto laws.

If the president does not like a bill passed by the legislative branch (Congress), they can veto it. This means the president rejects the bill and sends it back for reconsideration. However, Congress can override the presidential veto by passing the bill again with a two-thirds majority vote in both the House of Representatives and the Senate.

This system of checks and balances ensures that no single branch of government has too much power.

A set of skills, talents, and capabilities in which a firm is particularly strong is referred to as core competencies. The correct answer is D.  

 

EXPLANATION  

A core competency is an idea proposed in management theory. This concept can be described as "a harmonious combination of various resources and skills that makes management different from other companies.” The following three core competencies must be applied:

1. Having a unique product that is difficult for competitors to imitate.

2. Its products are able to provide significant contributions or benefits to customer problems.

3. Provides a lot of potential access to various markets.

Core competence is produced from a set of skills or specific production techniques that provide added value to customers. This allows an organization to access various markets.

In 1990 C. K. Prahalad and Gary Hamel wrote an article titled "Core Corporate Competencies.” In that article, they described that core competencies lead to the development of core products which can then be used to create many other products that benefit consumers. Core competencies are explored and grown through a long process, which makes a continuous improvement over a certain time instead of making instant big changes.

Answers

Mary may be exhibiting problems associated with Wernicke's area. 
People who have problems related to Broca's area also exhibit speech problems, however, when it comes to them, they can easily comprehend everything, but have a hard time trying to produce speech. On the other hand, patients with problems related to Wernicke's area don't have any problems speaking but their choice of words sounds nonsensical to everyone else but themselves.

Mary is likely experiencing Wernicke's aphasia, a fluent aphasia caused by damage to Wernicke's area, leading to speech with incorrect or missing content words while retaining grammatical structure.

Mary may be exhibiting problems associated with Wernicke's area, which is responsible for the comprehension of speech. The symptoms she presents, namely speaking fluently but with the wrong words, indicate a type of fluent aphasia commonly known as Wernicke's aphasia. This condition occurs when there is damage to the posterior part of the temporal lobe of the brain, which contains Wernicke's area. Unlike expressive aphasia, which is associated with Broca's area and affects speech production, Wernicke's aphasia leaves the patient's grammatical structure intact but the meaning is often lost because the content words are incorrect or missing.

Which best describes how Italy’s location on the Mediterranean Sea contributed to the flourishing of the Renaissance?

Answers

Final answer:

Italy's strategic position on the Mediterranean Sea facilitated trade and the import of ideas from the East, leading to immense wealth that supported the arts and cultivated a competitive and innovative atmosphere. This helped set the stage for the Renaissance, characterized by a focus on humanism and the revival of classical antiquity's literature and cultural practices.

Explanation:

Italy's location on the Mediterranean Sea greatly contributed to the flourishing of the Renaissance by acting as a central hub for trade and commerce. The Italian Trade Cities, thanks to their strategic positioning, played a crucial role in moving resources, culture, and knowledge from the East to Western Europe. Cities like Florence and Venice became immensely wealthy due to their economic activities, and this wealth enabled them to invest in the arts and patronize artists and intellectuals. Northern Italy, being a wealthy and urbanized region with a fragmented political landscape, saw various courts and princes vying for prestige through sponsorship of the arts. Additionally, the education system in Italy had a strong focus on the literature of Ancient Rome, which underpinned the humanistic values of the Renaissance. This academic focus, combined with the prosperity brought about by Mediterranean trade, created an environment ripe for cultural revival and innovation, leading to a burst of creativity and intellectual achievement that characterized the Renaissance.

Furthermore, Italy's connection to the Adriatic Sea and proximity to the Ottoman Empire played a part in making Europe a more interconnected place. Artists, like Crivelli, were able to move and serve patrons in different locations, spreading Renaissance ideas and artistic styles across the continent. This cross-pollination of ideas and art forms not only enriched Italy but also the rest of Europe.

Despite the fragmented city-states and frequent conflicts, the resulting environment was one of vibrant competition and cultural exchange. The small kingdoms, city-states, and papal lands that dotted the Italian peninsula constantly interacted, which encouraged innovation and the exchange of ideas necessary for the Renaissance to take hold. Economic stability backed by money from trade and the emergence of a new social class with financial power further cemented Italy as the starting point for this period of revival and transformation that eventually spread throughout Europe.

Answers

The use of  technical jargon that Mr. smith did to intentionally confuse Mr. Jabar is an example of noise.

What is noise?

Noise is defined as any unwanted sound that is considered unpleasant, loud, or disruptive to hearing. There is no difference between noise and desired sound in terms of physics, as both are vibrations through a medium such as air or water. The distinction occurs when the brain receives and perceives a sound.

Acoustic noise is any sound in the acoustic domain that is either intentional (e.g., music or speech) or unintentional. Noise in electronics, on the other hand, may not be audible to the human ear and may necessitate the use of instruments to detect.

Noise in audio engineering can refer to the unwanted residual electronic noise signal that causes acoustic noise to be heard as a hiss.

In experimental sciences, noise can refer to any random fluctuations in data that interfere with signal perception.

When children witness other children cry when getting a vaccination, and the witnesses then cry before the needle even touches them, it is an example of?

Answers

This is an example of vicarious conditioning.
Vicarious conditioning (VC) is a process of learning, whereby animals or humans acquire beliefs, attitudes and feelings towards a stimulus (in this case, the needle) based on observing others' responses and reactions towards it.In this instance, the children, through observing other children have "learned" to fear and get upset at the sight of a needle before it even touches them. 

The phenomenon is empathetic crying or emotional contagion. In the context of children witnessing others cry during vaccination, it is likely a combination of both empathy and emotional contagion.

Empathetic crying occurs when children, or even adults, witness another individual expressing strong emotions, such as distress or pain, and they respond by crying themselves. This is a form of empathy, where the observer is vicariously experiencing the emotions of the other person. Empathy involves the ability to understand and share the feelings of another, and in young children, this can manifest as crying when they see others in distress, even if they are not directly affected.

Emotional contagion is a related concept where the emotions of one individual or group are spread to and affect others. This can happen without the observers being fully aware of what is happening or without them fully understanding the reasons behind their emotional response. It is a basic form of empathy that does not necessarily require a deep understanding of the other person's situation but is more of an automatic, instinctive reaction to the emotions displayed by others.

The children who have not yet received the injection see another child in distress, which triggers an empathetic response, leading them to cry as well. This is a natural and common occurrence in young children who are still developing their emotional regulation skills.

You are assisting a patient on the phone when another patient walks up and starts to ask you detailed questions about his hospital bill. what should you do in this situation?

Answers

Politely acknowledge the in-person patient, explaining you're on a call and will attend to them shortly. After the call, provide them with attention or direct them to the proper billing department, always ensuring confidentiality and follow-through on providing the needed information.

When you are assisting a patient on the phone and another patient approaches with questions about their hospital bill, it's essential to uphold patient confidentiality and manage the situation professionally. Firstly, you should politely explain to the in-person patient that you are currently on a call and ask them to wait for a few moments. Ensure you maintain a friendly demeanor and communicate that you will address their concerns as soon as possible. If the nature of the in-person patient's questions about their bill is complex or contains sensitive information, it might be best to suggest a private setting where the discussion can occur without breaching confidentiality. This interaction reflects the importance of managing tasks and communicating efficiently within a healthcare environment. After concluding the call, follow up with the patient who was waiting, providing them with the necessary attention and information or referring them to the appropriate department for billing inquiries. It's essential to ask appropriate clarifying and follow-up questions to ensure understanding and to provide a thorough explanation when possible. Additionally, emphasize that any information the patient needs related to their health or billing will be addressed with the utmost care and respect for their privacy. Always remember to follow through with any promised action or information, as this demonstrates professionalism and that you are attentive to the patient's needs.

Final answer:

The assertion that employers have benefited the most from welfare reform is not definitively true or false. It depends on the specifics of the reforms and their broader socio-economic implications. The impacts on various demographic groups such as welfare recipients, taxpayers, and others should be considered.

Explanation:

The statement that 'The group that has benefited most by welfare reform is employers' is not definitively true or false as it depends on the specific circumstances and the form the welfare reform takes. However, employers could possibly benefit from welfare reforms if they discourage dependency on social benefits and encourage people to work, potentially expanding the pool of job seekers and possibly leading to lower wages. On the other hand, welfare reforms that provide skills training or education could increase the pool of skilled workers, also potentially benefiting employers. Yet, it would be inappropriate to state that employers are the group that has benefitted most from welfare reform without examining the impacts on other groups as well such as recipients of welfare, tax payers and more.
