A total of 850 insulation workers employed between 1940 and 1945 was identified from the personnel records of three large insulation manufacturing plants in the Midwestern U.S. in 1980. During the period 1940-1980, 28 deaths from lung cancer were discovered among the workers. Only eight lung cancer deaths, however, were reported among a comparable group of 800 coworkers who did not work with insulation during the same time period. The investigators had hypothesized that exposure to the insulation material increases the risk of lung cancer.

According to the recent Deary study in Psychology and Aging, as individuals grow older, their _____ scores _____.

i. dependability; show no relationship to earlier scores
ii. extraversion; show no relationship to earlier scores
iii. dependability; increase over time
iv. extraversion; increase over time

Answers

Answer:

The correct answer is C:

As individuals grow older, their dependability score increases over time.

Explanation:

Studies have shown that there is a strong correlation between aging and dependability.

Dependability here refers to the extent to which one relies on others in other to continue to carry out rudimentary mammalian functions.

Examples of such functions are:

WalkingGetting groceriesDoing Choresand other physically exerting activities.

This is not to say that there are no aging adults who go into the geriatric space with their mental strength and reasonable physical strength intact. The above happens because they have good genes and disciplined themselves to maintain a healthy lifestyle of good diets as well as mental and physical excercise.

A: experimental and quasi-experimental

B: case study and cross-sectional study

C: naturalistic observation and true experiment

D: naturalistic observation and survey

Answers

To study a person's behavior without intervention, use naturalistic observation and survey.

To study an individual or phenomenon, experiments or observational studies can be used. While experiments require manipulation by the investigator, observational studies do not require intervention.

Naturalistic observation involves studying an individual or element in its natural habitat without any form of manipulation. Notes are taken of observed attributes.

Surveys entail simply asking questions about the person without any form of intervention. People who know the individual could be respondents. Surveying the individual might warrant bias.

We can thus conclude that naturalistic observation and surveys are ways to study a person's behavior without intervention.

what is the relation between child development and learning​

Answers

Answer:

Child development is simply the developing of children from one age to the next. For example, the development between a pre-teen to a teenager. Not only can be for physical use it also affects children mentally. Children learn during child development causing them to mature faster which is the relation between child development and learning.

Hope this helped.

Many of the foundations of sophisticated forms of learning, including those important to academic success, are established in the earliest years of life. Development and early learning can be supported continuously as a child develops, and early knowledge and skills inform and influence future learning.


Some believe that learning leads to development whereas others contend that development leads to learning (Piaget). Learning awakens the developmental processes through social interactions with peers and teachers in such a way that it would not occur if the child were in isolation.Jun. 23, 2021

A British government ancestry site recently received more than 50 million hits, and access had to be restricted to cope with the demand. Due to this surge in interest, we have decided that our library records department will need to be reorganized in terms of staffing. In the past, we have received occasional requests for assistance in tracing documentation relating to family and business histories, but in the last two years the number of requests has reached a level that cannot be addressed by the existing staff alone. We are currently in the process of recruiting two additional specialists.Family history2 Traditionally, genealogy was thought of as finding out about your family tree. The idea was to find out who came before you, going as far back in history as possible. However, nowadays it is more common to want to find out as much detail about the people as possible, so what was a purely factual quest has become a historical process. This is an area that we are able to address, as our records include diaries and other documents that contain information and clues that can help build a more complete picture.Medicine and law3 In the past, most genealogical searches could be classified as vanity searches, because the motivation was to prove family nobility. However, this is no longer the case. One of the driving forces of the increased interest in genealogy has been in relation to illness. Genetics are now recognized as significant in predicting the likelihood of suffering from many types of diseases, including cancer and heart disease. There may also be a legal dimension to the searches, because inheritance claims often rely on ancestry. In both of these cases, we, as a department, must be particularly careful in relation to possible lawsuits, and we will be providing legal training to all relevant staff.Naming conventions4 The key starting point for any genealogical search is through surnames. Although first names, maiden names, and middle names are all significant, it is through surnames that most family history can be traced. For this reason, the department will be updating all of our databases with surname information. This is a skilled job, as spellings are often changed on documents as a result of clerical error. All staff will be involved in this process after appropriate training.Commercial aspects5 As mentioned earlier, genealogy is no longer a vanity hobby but has become a lucrative business. As a nonprofit organization, it is not our intention to compete in this market; however, we will need to cover the costs of increased staffing and training, so we will be charging a nominal fee for our services. The finance department is currently assessing the charges, which will be detailed in our next report. The fees will be reviewed on an annual basis.6 We thank all staff in advance for your cooperation in this exciting new opportunity for our department.
