Unit III PowerPoint Presentation
For decades, relational databases remained essentially unchanged; data was segmented into specific chunks for columns, slots, and repositories, also called structured data. However, in this Internet of Things (IoT) era, databases need to be reengineered because the very nature of data has changed. Today’s databases need to be developed with the needs of IoT in mind and have the ability to perform real-time processing to manage workloads that are dynamic. For example, relational databases should be able to work with real-time data streaming and big data (an example was presented in the Unit III Lesson).
Scenario: Falcon Security wants their customers to be able to view security video footage in real-time and provide customers with the ability to query video footage for viewing. Choosing a database solution such as MongoDB would allow Falcon Security to store customer video footage in the same database as the metadata.
To do this, Falcon Security needs a way to manage the demands of real-time data streaming for real-time analytics. Conduct some research for a NoSQL database application, such as MongoDB or Cassandra, that could meet this need. How would switching to a real-time database solution help Falcon Security remain competitive? Create a PowerPoint presentation that includes the components listed below.
Provide a brief introduction to IoT.
Present the argument to the Falcon Security CEO that switching to a more dynamic database structure (NoSQL real- time database) will meet the demands of IoT.
Introduce some features of the database you chose, whether it is MongoDB, Cassandra, or another database. Describe how switching to a more dynamic database will give Falcon Security a competitive advantage.
Your presentation must be a minimum of six slides in length (not counting the title and reference slides), and you must use at least two academic resources. Any information from a resource used must be cited and referenced in APA format.
Unit IV
When you started your small business, you managed all business processes on your own. Now, your business is expanding and you have hired employees to help. Would you consider implementing an enterprise resource planning (ERP) system, or would you continue to use applications, such as Microsoft Office (e.g., Word, Excel, Access), to manage your business processes? Be sure to explain the reasons behind your choice.
Your journal entry must be at least 200 words. No references or citations are necessary.
Unit IV
Scenario: A company called Colony Nursery and Landscaping opened a new store located a few hundred miles away from its original location. The company wants to implement an award system that awards their customers with points whenever customers make a purchase, but the two stores are not able to share information. Colony Nursery and Landscaping will need to implement an enterprise resource planning (ERP) system that will solve the information silo problem by collecting and making this user data available. Colony Nursery and Landscaping is hoping that by providing customers with this award
Information Systems Management 3
system, they will be able to maintain competitive advantage. Colony Nursery and Landscaping cannot afford to purchase, develop, or maintain this system on-site, so they are investigating cloud solutions.
In addition, for many organizations, Colony Nursery and Landscaping included, information silos make it difficult to tap into needed information. Discuss whether or not the problem of information silos can be solved by using the cloud. Some organizations do not have the resources to construct or maintain their computer infrastructure, so they utilize cloud services instead to reduce costs and improve scalability. In this assignment, you will discuss whether or not the cloud offers solutions for Colony Nursery and Landscaping and identify an application that the ERP system could provide. Compose an essay that includes the elements listed below.
Define what an information silo is.
Explain why information silos are a problem for organizations.
Discuss why organizations are moving to the cloud.
Determine whether or not using cloud services, such as a cloud-based host for data storage, would solve the ERP information silo problem at Colony Nursery and Landscaping.
Explain how using the ERP system and awards program would provide a competitive advantage for Colony Nursery and Landscaping.
Discuss why the implementation of an ERP system might require business process reengineering for Colony Nursery and Landscaping. Be sure to explain the business processes that will be affected (e.g., the customer awards system). Use diagrams or tables as needed, but this is not required.
Your essay must be a minimum of two pages in length (not counting the title and reference pages), and it must be formatted in APA style. You should include an introduction section that gives background and context to your reader. You must use at least two scholarly resources as references. Any information from these resources must be cited and referenced in APA format.

Should he accept Jones’s statement as a denial of participation in the project to maintain anonymity?

Case study dilemma: Should he accept Jones’s statement as a denial of participation in the project to maintain anonymity? Should he accuse Jones of lying? Should he drop the matter for the moment and later tell Cash about the incident? Perhaps Cash had lied about interviewing Jones? Should be confront Cash with this suspicion? Since it was some distance to the field site from the university, should he [Jordan] now seek out other informants Cash had reported on to determine whether or not they had been interviewed? Or, were there other tactics to be employed?

hypothesis as discussed | Nursing School Essays

After reading the feedback on your proposed quantitative research question in M1 Assignment 2, provide your revised quantitative research question. Next, develop a hypothesis for the research question (Include a null and an alternative hypothesis for your question.).
Keep in mind that a hypothesis is a specific statement of prediction. A hypothesis describes in concrete (rather than theoretical) terms what you expect will happen in your study. It should be testable and often mirrors the research question in the way that it is written.
For example, there is a positive correlation between having an alcoholic parent and alcoholism in adulthood.
Once you have clearly stated your research question and hypothesis, discuss the following (in 1–2 pages):

Why is a null hypothesis required in research? How is the null hypothesis used when drawing conclusions from the collected data?
What is the relationship of your hypothesis to the identified problem?
How is your hypothesis feasible?
How is your hypothesis measurable and testable?

However, I want to point out that you should not use Wikipedia as a source for your coursework. Here’s an article discussing the limitations of Wikipedia.
http://www.findingdulcinea.com/news/education/2010/march/The-Top-10-Reasons-Students-Cannot-Cite-or-Rely-on-Wikipedia.html
Example: Science in the Social Sciences
The textbook begins with a quote from Albert Einstein: “Science is the attempt to make the chaotic diversity of our sense-experience correspond to a logically uniform system of thought” (p. 5).
– Truth is not created. It is discovered. Science is an organized attempt to discover truth.
The book clarifies the 3 main categories of science:
1) Natural: study of natural phenomena (cosmological, geological, chemical, biological, etc.)
2) Formal: study of math and logic that use an a priori, rather than factual, methodology (basically, a priori is knowledge that we have and can apply , rather than needing to measure something to gain knowledge about it)
3) Social: study of human behavior and sciences
Einstein was a theoretical physicist; this falls under formal sciences. He did not like things that were unpredictable an he was bothered by chaos. He tried to find ways to predict the unpredictable.
In this class:
We are interested in social sciences, and in particular how that knowledge can be applied to help systems of all sizes. Human services apply methods and findings from social science to improve the lives of people (individuals, groups – such as families, and larger social context – communities).
At the same time, all sciences have a lot in common. The textbook discusses the example of chaos theory. Chaos theory is a branch of mathematics (which is a science itself). Chaos theory deals with conditions where prediction is not possible.
– Chaotic diversity describes things on the quantum level and the human condition
– Chaos theory has implications when working with people; this was recently realized
– Human Services dislike chaos; we want to explain, possibly predict, and prevent human misery
* We can take another look at Einstein’s quote: “Science is the attempt to make the chaotic diversity of our sense-experience correspond to a logically uniform system of thought” (p. 5).
He is telling us:
– we have a rich and imaginative sensory capacity that provides us with a vast way of experiencing and interpreting our world
– at the same time (from an evolutionary standpoint) our sensory capacity is built for survival in the heat of the moment, rather than cool calculation of empirical analysis
– Things like intuition and instinct are useful, but we can add science to our toolbox. Through science, we can explore our world in a way to test our assumption and theories. Science helps us increase our rational understanding of the world.
Who talks more?
Knowledge through theories/assumptions vs Knowledge through Science
Many people believe that women tend to talk more than men.
– Some have suggested the difference has a biological basis
– One estimated that’s often cited is that women spoke 20,000 words p/day and men spoke 7,000 words p/day.
– The claim seemed plausible, and a group of psychologists decided to find out if it was true. What did they do?
1) Checked the literature to see if anyone had actually counted (no one had). Instead, they just found theories and assumptions that were often based on cultural stereotypes
2) Conducted a research study with 369 men and women. They concluded men and women speak roughly the same amount.
* This study is used as an example to show that research can show us that sometimes what we think is true, really isn’t.
* Why is this important in the field of Human Services?
– Because what we believe about people, and how they behave, is fundamental to effectively work with clients. What we believe can sometimes be wrong, inaccurate, or incomplete.
– We should keep in mind as professionals, whenever possible, to act according to the best information that we have on hand. This means we need to be informed as to what science has empirically indicated.
Understanding Science
Science and Human Services
Human Services is a profession, rather than a science. It draws on our profession’s research, as well as the research of colleagues in other disciplines such as social work, anthropology, sociology, education, etc. So, Human Services is interdisciplinary.
– Some disciplines are considered social science (like psychology) and some are considered professions (like Human Services)
– We are all engaged in research to find the best methods for helping the human condition
– Human Service professionals engage in the research process; human services practice should be based on empirical research whenever possible.
Empirically Based Research
This is considered a best practice, and Human Service practitioners should try to only use techniques, methods, and approaches that are empirically derived.
Empirically based practice means using quality research from peer reviewed sources in your professional practice. How?
– professional journals
– online databases
– continuing education
– assessing the results of your practice in an ethical way
The Emergence of Science and the Scientific Method
The scientific method is “a method or procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses.” (according to Oxford Dictionaries Online)
– The method has expanded from the natural sciences into social sciences to include disciplines such as anthropology, sociology, psychology, social work, and Human Services.
A few important people in the emergence of science. Throughout history, people have struggled to make this unpredictable and sometimes dangerous place more tolerable and predictable.
– Francis Bacon (1561 – 1626): considered first person to conceptualize scientific method
– Galileo (1564 – 1642)
– Copernicus (1473 – 1543)
– Plato, Socrates, and Aristotle
– Knowledge has been gained slowly, but it accumulates over the years.
– The scientific method was just one innovation, but it forms the foundation for all modern research.
We have a legal, moral, and ethical responsibility to our profession, ourselves, society, and our clients to use science.
* while not all Human Service practitioners are engages in research, all practitioners are consumers of research in their personal and professional lives.
What are the Modern Features of Science?
1) Systematic Empiricism
2) Scientific Approach
3) Public Knowledge
1) Systematic Empiricism: learning based on observation.
– Scientists learn about the world by carefully planning observations, making observations, recording observations, and analyzing those observations
– A lot of what we know (which may or may not be true) is acquired haphazardly
– Within science, logical reasoning and creativity play important roles. Scientists are unique in their insistence on checking ideas about the way the world seems to be.
– Instead of knowledge through tradition, superstition, guessing, etc., science uses systematic observation to gain knowledge. Look at the “Who Talks More” example; the researchers did not trust other people’s stereotypes or their own informal observations. Instead, they systematically recorded, counted, and compared the number of words spoken by a large sample of women and men.
Summary
The textbook discusses the concept of science and how it relates to Human Services. Through discussion and examples, the important role that research plays in Human Services is addressed. Human Service professionals need to understand and utilize research and its scientific principles in order to effectively do their job, and not rely on informal observations, guessing, traditions, etc. for knowledge when working with clients. While Human Service practitioners may not conduct research, it’s crucial to understand how scientific research fits into practice. In my past work experiences, I have used the research of others, as well as conducted my own research, and so I’ve found what is said on these pages to be very true. To better comprehend situations and provide the best services, practitioners need to be able to understand and utilize the concepts of social research.
