a. They refer to the smallest amount of change between two stimuli that a person can detect half of the time.
b. They are also referred to as just noticeable differences (JND).
c. They require a change of at least 5 percent between the original stimulus and the final stimulus in order to be detected.
d. They change depending on the cost of making an error, motivation, and personality

Answers

Answer 1

The statement that is TRUE about absolute thresholds is a. They refer to the smallest amount of change between two stimuli that a person can detect half of the time.

1. Absolute thresholds refer to the minimum amount of stimulus intensity needed for a person to detect a stimulus 50% of the time.

2. Option a. states that absolute thresholds refer to the smallest amount of change between two stimuli that a person can detect half of the time. This statement accurately describes absolute thresholds.

3. Option b. states that absolute thresholds are also referred to as just noticeable differences (JND). This is incorrect. Just noticeable differences (JND) refer to the smallest difference in stimulus intensity that can be detected between two stimuli.

4. Option c. states that absolute thresholds require a change of at least 5 percent between the original stimulus and the final stimulus to be detected. This is not true. Absolute thresholds are determined by the minimum amount of stimulus intensity, not by a specific percentage change.

5. Option d. states that absolute thresholds change depending on the cost of making an error, motivation, and personality. This is incorrect. Absolute thresholds are generally consistent for a given sensory system and do not change based on factors like cost, motivation, or personality.

Therefore, the only statement that is TRUE about absolute thresholds is option a. They refer to the smallest amount of change between two stimuli that a person can detect half of the time.

Quattrone (2015) described how ‘the dynamism of logics is no longerthought to reside in the logics themselves’ (P.412).Withreferenceto three performance indicators, Return on Capital Employed (ROCE), Economic Value Added (EVA) and Free CashFlow (FCF) which are used in capital, and knowledge-intensive organization, critically discuss your understanding of this statement, and what this means for the practice of organizational performance

Answers

According to Quattrone (2015), the dynamism of logics is no longer thought to reside in the logics themselves. The meaning of this statement is that knowledge-intensive organizations should focus more on the context and meaning of financial logics rather than simply applying them for the sake of it.

This is especially true when considering the three performance indicators: Return on Capital Employed (ROCE), Economic Value Added (EVA), and Free Cash Flow (FCF). These metrics are often used as measures of organizational performance, but their effectiveness depends on the context and meaning behind them. The main issue with simply using these indicators is that they can be misleading when used in isolation. For example, ROCE may appear high, but this may be because of high leverage rather than strong business performance. Similarly, EVA may appear high, but this may be due to cost-cutting measures rather than generating value. FCF may appear high, but this may be due to delaying investments in long-term growth.
Therefore, knowledge-intensive organizations need to critically examine the meaning and context of these performance indicators to gain a more comprehensive understanding of organizational performance. This requires looking beyond the numbers and considering factors such as strategy, innovation, and risk management. Only then can the true value of these performance indicators be realized, and organizational performance can be improved.

Zoë has been working as an RECE in a family support program for two years. The Wilson family began attending the drop-in when they moved into the area and were looking to meet other families while both parents sought work.
Zoë had gotten to know Miriam Wilson and her parents over the past 10 months, and had formed a particularly strong relationship with the mother. Recently, Zoë had begun to notice a change in Miriam and her mom. They were quieter and seemed less engaged with the program and the other families.
One day, when her mother was helping her get her coat on, Miriam’s t-shirt lifted to expose her torso and lower back. Zoë gasped when she noticed a large bruise that covered Miriam’s tummy and lower back.
After the Wilsons left, Zoë spoke to her supervisor immediately. The centre supervisor listened to Zoë describe the experience and said: "Oh Zoë, you should not jump to conclusions or stir anything up. Just keep an eye on them over the next few weeks to see if any other concerns arise before calling the Children’s Aid Society to make a report."
Zoë felt uncomfortable ignoring the bruise that she saw, but she listened to the advice of her supervisor who had more experience with this kind of thing, and went home. She never saw the Wilsons again.


Reflecting on the Scenario
1. Identify and reflect on the facts of this scenario? What ethical and professional responsibilities does Zoë need to consider.
2. What is the role of the supervisor? Did the supervisor uphold or fail to uphold her ethical and professional responsibilities?
• What would you have done if Zoë had come to you with the same concerns?
• Which resources would you guide her to?
• What would support your decision-making?
3. How would the Code of Ethics and Standards of Practice support Zoë in managing this situation? Which standards would you review to support you in this situation?
4. What do you know about the Child, Youth and Family Services Act and your duty to report suspected child abuse and neglect to a Children’s Aid Society?

Answers

Facts of the scenario and ethical/professional responsibilities for Zoë:

Zoë has noticed a change in Miriam and her mother's behavior, indicating a potential issue.

Zoë observed a large bruise on Miriam's tummy and lower back.

Ethical responsibilities: Zoë has a duty to ensure the well-being and safety of the children in her care. She must consider the potential for child abuse or neglect and take appropriate action to protect the child.

Professional responsibilities: As a Registered Early Childhood Educator (RECE), Zoë is bound by professional standards to advocate for the best interests of children and to report any suspected abuse or neglect.

Role of the supervisor and their ethical/professional responsibilities:

The supervisor's role is to provide guidance and support to staff members.

The supervisor failed to uphold their ethical and professional responsibilities by downplaying Zoë's concerns and advising her not to report the suspected abuse immediately.

If Zoë had come to me with the same concerns, I would prioritize the well-being of the child and follow the legal and ethical obligations to report suspected child abuse or neglect.

I would guide Zoë to resources such as the local Children's Aid Society or child protection services for guidance on reporting procedures and further support.

My decision-making would be supported by the commitment to protect children from harm, ethical guidelines, and legal obligations to report suspected abuse or neglect.

The Code of Ethics and Standards of Practice:

The Code of Ethics for RECEs emphasizes the responsibility to prioritize the well-being and safety of children.

Standard I: Responsibility to Children explicitly states the obligation to take action if there are reasonable grounds to suspect abuse or neglect.

Standard IV: Responsibility to Community emphasizes the importance of collaborating with other professionals and agencies to ensure the well-being of children.

These standards would support Zoë in recognizing her duty to report the suspected abuse and seek appropriate intervention to protect the child.

Child, Youth and Family Services Act (CYFSA) and duty to report:

The CYFSA outlines the legal duty of professionals, including RECEs, to report suspected child abuse or neglect to a Children's Aid Society.

Professionals are required to report if they have reasonable grounds to suspect that a child is in need of protection.

Failure to report can result in legal consequences.

Zoë would have a legal obligation to report the suspected abuse immediately to the Children's Aid Society, ensuring the child's safety and well-being are prioritized.

________.

Answers

Sarah has come to a place in her life where she understands and is comfortable with herself as a unique individual. According to Erikson, this ultimate psychosocial goal is called identity formation.

According to Erik Erikson's theory of psychosocial development, the ultimate goal during adolescence and young adulthood is achieving a sense of identity. This stage, known as "identity formation" or "identity achievement," is a crucial psychosocial milestone.

When Sarah reaches a point in her life where she understands and accepts herself as a unique individual, it signifies that she has successfully navigated this stage of development. Identity formation involves developing a clear and coherent sense of self, including one's values, beliefs, goals, and aspirations. It encompasses various aspects such as self-awareness, self-esteem, and self-concept.

During this stage, individuals explore different roles, possibilities, and identities in order to establish a strong sense of who they are as individuals. They may explore various interests, values, and relationships, trying out different personas and gradually shaping their identity based on personal experiences and social interactions.

Attaining a sense of identity is crucial for healthy psychosocial development. It provides individuals with a solid foundation and a clear understanding of their values and beliefs, enabling them to make informed decisions, establish meaningful relationships, and navigate life's challenges with confidence.

It is important to note that achieving a sense of identity is not a one-time event but an ongoing process that continues throughout life. Individuals may revisit and refine their identities as they encounter new experiences and challenges. Successful identity formation lays the groundwork for subsequent stages of development, allowing individuals to tackle future psychosocial tasks with a sense of self-assuredness and a clear understanding of their identity.

One of the important features of deregulation is the way the private enterprises operate. How a country can bring this into activity. Conclude your opinion by giving examples of deregulation.

Answers

Deregulation is a mechanism that reduces or eliminates government regulation of business activities in a particular industry or sector. Deregulation is primarily aimed at increasing competition by lowering entry barriers to the industry, lowering the cost of doing business, and increasing innovation.

One of the important features of deregulation is the way private enterprises operate. In order to bring this into activity, countries should:

Encourage private participation in the business environment

Encourage domestic and foreign investment by providing a favorable tax environment

Introduce competition policies and laws that promote competitive behavior among market players

Provide a suitable legal framework to guide business operations

Give incentives for innovation and entrepreneurship

Examples of deregulation: The airline industry in the US was deregulated in 1978 by the Airline Deregulation Act.

Before deregulation, airlines needed to receive approval from the Civil Aeronautics Board before changing routes, fares, or adding new flights. The result of deregulation was an increase in the number of airlines and a decrease in fares.

The Telecommunications Act of 1996 deregulated the telecommunications industry in the US. The Act allowed for competition between telephone companies, cable companies, and internet service providers. It also required telecommunications companies to offer their services to all customers at reasonable rates.

The result of the deregulation was a decrease in the cost of long-distance phone calls and the emergence of new technology like Voice over Internet Protocol (VoIP).

The conclusion is that deregulation can have a positive impact on business operations, innovation, and competition.

Countries that want to bring this into activity should create a conducive environment for business operations, introduce competition policies, provide a suitable legal framework, and give incentives for innovation and entrepreneurship.

classical conditioning

Answers

Classical conditioning is a type of learning in which a neutral stimulus is paired with a naturally occurring stimulus.

In the case of Maureen, the initial experience of eating a breakfast burrito while standing in line for the roller coaster that turns riders upside down may have created a strong association between the breakfast burrito and the feeling of sickness she experienced, going on the ride.

When Maureen tries to eat a breakfast burrito again a week later, her brain recognizes the neutral stimulus (the sight, smell, or taste of the breakfast burrito) and associates it with the unconditioned stimulus.

This is an example of classical conditioning because the learned response is based on the association between two stimuli, rather than on the consequences of the behavior itself.

which type of classification deals with why climate types occur where they do?

Answers

The type of classification that deals with why climate types occur where they do is called climatology.

Climatology is the scientific study of climate, which is the average weather conditions over a long period of time in a particular region.

Climatology seeks to understand the factors that determine the climate of a particular region, such as the position of the Earth in relation to the sun, the shape and size of the landmass, the ocean currents, and the altitude and orientation of the land. By understanding these factors, climatologists can explain why climate types occur where they do and how they may change over time.

Climatology also involves the analysis of climate data, such as temperature, precipitation, and wind patterns, to understand long-term climate trends and patterns. This information is important for a variety of applications, including agriculture, public health, and natural resource management.
