What is hematology? Hematology is the study of blood and blood disorders. Hematologists and hematopathologists are highly trained healthcare providers who specialize in diseases of the blood and blood components. These include blood and bone marrow cells.
 
What is the difference between a hematologist and a hematopathologist?


A hematologist is usually a board-certified internist, or pediatrician who has completed additional years of training in hematology. The hematologist generally focuses on direct patient care and diagnosing and managing hematologic disease, especially cancers.


A hematopathologist is usually board-certified in both anatomical and clinical pathology and has additional years of training in hematopathology. Hematopathology is not only the study of disease of the blood and bone marrow. It is also the study of the organs and tissues that use blood cells to perform their physiologic functions. These include the lymph nodes, the spleen, thymus, and other lymphoid tissue. The hematopathologist focuses on the diagnosis of conditions of the hematopoietic and lymphocyte-rich tissues. This is usually done by direct exam of tissue and blood in the lab. 

The incidence of dengue has grown dramatically around the world in recent decades. A vast majority of cases are asymptomatic or mild and self-managed, and hence the actual numbers of dengue cases are under-reported. Many cases are also misdiagnosed as other febrile illnesses [1].
One modelling estimate indicates 390 million dengue virus infections per year (95% credible interval 284–528 million), of which 96 million (67–136 million) manifest clinically (with any severity of disease) [2]. Another study on the prevalence of dengue estimates that 3.9 billion people are at risk of infection with dengue viruses. Despite a risk of infection existing in 129 countries [3], 70% of the actual burden is in Asia [2].
The number of dengue cases reported to WHO increased over 8 fold over the last two decades, from 505,430 cases in 2000, to over 2.4 million in 2010, and 4.2 million in 2019. Reported deaths between the year 2000 and 2015 increased from 960 to 4032.



This alarming increase in case numbers is partly explained by a change in national practices to record and report dengue to the Ministries of Health, and to the WHO. But it also represents government recognition of the burden, and therefore the pertinence to report dengue disease burden. Therefore, although the full global burden of the disease is uncertain, this observed growth only brings us closer to a more accurate estimate of the full extent of the burden.

Nutrition information provides insights into the essential nutrients and their quantities found in food, aiding in making informed dietary choices to support health and well-being. 



 






Here's a breakdown of key aspects of nutrition information:


1. What is Nutrition?



Nutrition is the process of taking in food and converting it into energy and other vital nutrients required for life. 



 




It involves the body's ability to ingest, digest, absorb, and utilize nutrients from food for growth, development, and maintaining health. 



 





Essential nutrients include carbohydrates, proteins, fats, vitamins, minerals, dietary fiber, and water. 



 







2. Why is Nutrition Important?








Growth and Development:
Proper nutrition is crucial for the healthy growth and development of children and adolescents. 



 












Health and Well-being:
It supports overall health and well-being, contributing to a strong immune system and reducing the risk of chronic diseases. 



 












Energy:
Nutrients provide the body with the energy it needs to function, move, and perform daily activities. 



 












Disease Prevention:
A balanced diet can help prevent or manage various diseases, including heart disease, diabetes, and certain cancers. 



 












3. Key Nutrients and Their Functions:




Carbohydrates: The body's primary source of energy.
Proteins: Essential for building and repairing tissues, and also provide energy.
Fats: Provide energy, support cell function, and help the body absorb certain vitamins.
Vitamins and Minerals: Crucial for various bodily functions, including immune function, bone health, and nerve function.
Dietary Fiber: Aids in digestion and promotes healthy bowel movements.
Water: Essential for all bodily functions, including hydration and nutrient transport. 



 








4. How to Find Nutrition Information:








Food Labels:
Most packaged foods have nutrition information labels that list key nutrients and their amounts per serving. 



 












Online Resources:
Websites and apps provide nutritional information for various foods and recipes. 



 












Consult Professionals:
Registered dietitians or nutritionists can offer personalized guidance on nutrition needs. 

At the most basic level, nutrition is about eating a regular, balanced diet. Good nutrition helps fuel your body. The foods you eat supply the nutrients your body needs to maintain your brain, muscle, bone, nerves, skin, blood circulation, and immune system. Proper nutrition also helps protect you from illness and disease such as heart disease, diabetes, cancer, and osteoporosis.
There are two major classes of nutrients in food: macronutrients and micronutrients. Macronutrients are carbohydrates, protein, and fat. They supply energy (in the form of calories) and serve as the building blocks for muscles and tissues.
In comparison, micronutrients are individual vitamins and minerals. They are divided into four categories: water-soluble vitamins, fat-soluble vitamins, microminerals, and trace minerals.
 
While most foods in plant-based diets offer important health benefits, certain ones stand out. These "superfoods" pack the biggest nutritional punch. People should try to eat some of these healthy foods every day or as often as possible. They include the following:

Berries. High in fiber, berries are naturally sweet, and their rich colors mean they are high in antioxidants and disease-fighting nutrients.
Fatty fish. Fatty fish can be a good source of protein and omega-3 fatty acids, which help prevent heart disease. Those with the highest omega-3 content are salmon, mackerel, trout, anchovies, and sardines.
Leafy greens. Dark, leafy greens are a good source of vitamin A, vitamin C, and calcium, as well as several phytochemicals (chemicals made by plants) that fight inflammation and protect cells from damage.
Nuts. Hazelnuts, walnuts, almonds, and pecans are good plant protein sources. They also contain monounsaturated fats, which may be a factor in reducing the risk of heart disease.
Olive oil. Olive oil is a good source of vitamin E, polyphenols, and monounsaturated fatty acids, all of which help reduce the risk of heart disease.
Whole grains. A good source of soluble and insoluble fiber, whole grains also contain several B vitamins and minerals. They have been shown to lower cholesterol and protect against heart disease and diabetes.
Yogurt. A good source of calcium and protein, yogurt contains live cultures called probiotics. These "good bacteria" can protect the body from other harmful bacteria.
Cruciferous vegetables. These include broccoli, Brussels sprouts, cabbage, cauliflower, collard greens, kale, kohlrabi, mustard greens, radishes, and turnips. They are an excellent source of fiber, vitamins, and phytochemicals, which may help prevent some types of cancer.
Legumes. This broad category includes kidney, black, red, and garbanzo beans, soybeans, and peas. Legumes are an excellent source of fiber, folate, and protein; studies show they can help reduce the risk of heart disease.

 

REF: https://courses.lumenlearning.com/wm-organizationalbehavior/chapter/what-is-organizational-behavior
In a nutshell, organizational behavior is the study of how human behavior affects an organization. Organizational behavior aims to learn how an organization operates through the behaviors of its members. Instead of taking a strictly numerical approach to determine an organization’s operations, it takes a more psychological approach. By understanding people, you can better understand an organization
 
The academic study of organizational behavior can be dated back to Taylor’s scientific theory . However, certain components of organizational behavior can date back even further. In this section we will discuss how organizational behavior developed into a field of its own.
Looking back thousands of years we can find components of organizational behavior. Famous philosophers like Plato and Aristotle discussed key components of today’s organizations including the importance of leadership and clear communication. While these seem like very basic and broad concepts today, at the time they were innovative ideas and helped to lay the foundation for organizational behavior.
If organizational behavior were a simple topic, this course would be short and sweet. We could simply say that organizational behavior is how people and groups act within an organization. But it’s not so simple!
When organizational behavior grew into an academic study with the rise of the Industrial Revolution, it began to complicate what could appear to be simple topics. People began asking a lot of questions and started critiquing how organizations operated. Like many academic ventures, people began to deep dive into how behavior plays a role in organizations and why changes in behavior alter the way organizations operate. Along the way, organizational behavior has grown to incorporate components of management, psychology, leadership, personality traits, motivation, etc.
Organizational behavior has grown into its own niche within a wide variety of other genres. This is exciting because it allows us to really investigate each and every aspect of behavior within an organization! Today, organizational behavior is recognized as an essential component of an organization. Scholars and businesses alike recognize its importance and continue to help it adapt to current issues and new findings.

 Hemoglobin is an iron-rich protein in red blood cells (RBCs).   The normal hemoglobin range for men is 13.5 to 17.5 gm/dL and 12 to 15.5 gm/dL for women. It is of utmost importance to maintain hemoglobin concentration.

Tips to increase your hemoglobin levels

What functions does hemoglobin perform in our bodies? 
Hemoglobin is vital for carrying oxygen from the lungs to tissues and organs. It also transports carbon dioxide from the tissues back to the lungs.
What causes low hemoglobin?

Some common causes of low hemoglobin are:

Substantial blood loss
Deficiency in iron, vitamin B, and folate
Kidney disease
Hypothyroidism
Thalassemia
Lung diseases
Excessive smoking

Any type of blood loss can cause anemia, including blood loss from surgery, heavy menstrual periods, and bleeding in the gastrointestinal tract. 
Symptoms of low hemoglobin
You can detect extremely low hemoglobin levels in your system in a few ways. They include

A fast or irregular heartbeat
Fatigue
Frequent or unexplained bruising
Shortness of breath
Liver and kidney disease
Pale skin and gums
Muscle weakness
Reoccurring headaches
Dizziness
Poor appetite
Anemia in severe cases

Elevated hemoglobin levels are associated with dehydration, heart failure, and chronic lung disease. In some conditions, the bone marrow may not produce enough RBCs, leading to cancers like leukemia, lymphoma, or tumors that spread from other parts of the body into the bone marrow.
What are the foods that can improve your hemoglobin levels?

It is essential to boost your food intake to raise your hemoglobin levels. Here are some foods to increase hemoglobin levels:

Iron-rich foods: Consume iron-rich foods like fish, meat, eggs, soy products, broccoli, green leafy vegetables that include spinach, fenugreek leaves, cauliflower, green peas, cabbage, green beans, nuts and seeds, and peanut butter, to increase your hemoglobin levels.
Vitamin A: It is pertinent to consume vitamin A foods to increase hemoglobin as they absorb more iron. Vitamin A and beta-carotene can help you there. Vitamin A is found in animal food sources, such as fish and liver. Beta-carotene is found in red, yellow, and orange fruits and vegetables.
Folate: Folate is a type of Vitamin B that plays an essential part in hemoglobin production. A shortage of folate can prevent the red blood cells from maturing, leading to anemia. Some good sources of folate include beef, rice, black-eyed peas, kidney beans, lettuce, and peanuts.
Foods rich in vitamin C: A combination of iron and vitamin C can prove to be beneficial. The latter is used for better absorption of iron. Foods rich in vitamin C include oranges, lemon, strawberries, papaya, bell peppers, broccoli, and tomatoes.
Fruits: It is also perfect to have fruits like beetroot, apple, watermelon, papaya, oranges, litchis, kiwis, strawberries, grapefruit, banana, and peach, which can boost hemoglobin levels. Plus, dry fruits, like dates, can increase the number of erythrocytes, thereby increasing hemoglobin levels. They contain iron, vitamin C, vitamin B complex, and folic acid, which helps in the formation of red blood cells. Raisins are also a rich source of iron and copper necessary to form red blood cells.

Avoid iron blockers: Foods that block your body’s ability to absorb iron, such as coffee, tea, alcohol, and aerated drinks, should be avoided.
Tips to increase your hemoglobin levels
Here are some tips to keep in mind to increase your hemoglobin levels:
Switch to brown rice: As a superfood, brown rice can help prevent various diseases related to cholesterol and the gastrointestinal system. It is rich in iron, containing 0.52 milligrams of iron for every 100 grams.
Enjoy dark chocolate: With over 80% of cocoa, dark chocolate naturally improves hemoglobin levels. Plus, it is loaded with minerals, nutrients and antioxidants.
Drink nettle tea: The spice nettle has also proven to be a good source of iron and vitamin B and C. They can also play a part in increasing hemoglobin levels.
 Exercise: Take up moderate to high-intensity exercise to help your body produce more hemoglobin to meet the oxygen demands of your body.

Big data:Big data refers to the large, diverse sets of information that grow at ever-increasing rates. It encompasses the volume of information, the velocity or speed at which it is created and collected, and the variety or scope of the data points being covered (known as the "three v's" of big data).

Big data is a great quantity of diverse information that arrives in increasing volumes and with ever-higher velocity.
Big data can be structured (often numeric, easily formatted and stored) or unstructured (more free-form, less quantifiable).
Nearly every department in a company can utilize findings from big data analysis, but handling its clutter and noise can pose problems.
Big data can be collected from publicly shared comments on social networks and websites, voluntarily gathered from personal electronics and apps, through questionnaires, product purchases, and electronic check-ins.
Big data is most often stored in computer databases and is analyzed using software specifically designed to handle large, complex data sets.
How Big Data Works
Big data can be categorized as unstructured or structured. Structured data consists of information already managed by the organization in databases and spreadsheets; it is frequently numeric in nature. Unstructured data is information that is unorganized and does not fall into a predetermined model or format. It includes data gathered from social media sources, which help institutions gather information on customer needs.






 






Big data can be collected from publicly shared comments on social networks and websites, voluntarily gathered from personal electronics and apps, through questionnaires, product purchases, and electronic check-ins. The presence of sensors and other inputs in smart devices allows for data to be gathered across a broad spectrum of situations and circumstances.

What if I told you about this magical teaching practice that, done even once, produces large improvements in student final exam scores[1], helps narrow the grade gap between poorly prepped and highly prepped first year college students[2], and might even result in more positive course reviews[3],[4]? What if I also told you this magical teaching practice is something you already know how to do? What if I told you, the secret to increasing your students’ success and  overall satisfaction is……more TESTS!?
Okay…well to be fair, it’s a little more nuanced than that. While adding just one test to a class does indeed improve final exam scores, it turns out that more frequent, graded exercises in general improve learning outcomes for students [2],[5]. Even better – if these exercises are low stakes, they can improve learning outcomes without increasing student anxiety [4],[6].
We often view testing as an unpleasant but necessary way to assess student performance. It may be time for us to instead view testing as a useful teaching tool and to implement an assessment system that maximizes the potential learning benefits. In this post I will discuss the important known benefits of frequent, low stakes assessments as well as some practical tips for how to maximize these benefits without adding undue stress to your life or the lives of your students.

Benefit #1: “Thinking about thinking”
Testing can improve a student’s metacognition, or their ability to “think about thinking.” A good metacognitive thinker understands how their thought processes work and can pay attention to and change these processes [7]. A student with strong metacognitive skills can therefore more successfully monitor, evaluate, and improve their learning compared to students lacking these skills. Unfortunately, many students struggle with metacognition and must contend with “illusions of mastery” (or thinking they understand a subject better than they actually do).  Self-testing is a good way to prevent illusions of mastery, but many students do not incorporate self-testing into their studying, instead electing more passive modes of exam preparation such as rereading texts[8]. Incorporating more testing into the curriculum forces students into the position of making mistakes and receiving feedback, allowing them to frequently measure their learning in relation to expectations and adjust accordingly. Again, note that providing feedback is an essential part of this process.

Benefit #2: Practice Remembering
Testing can improve a student’s long term memory of information presented in class by forcing students to recall what they’ve learned through a cognitive process called active retrieval. Active retrieval strengthens neural pathways important for retrieving memories, allowing these memories to be more easily accessed in the future.
While any sort of retrieval practice is useful, it is most beneficial when it is effortful, spaced, and interleaved.  An example of effortful retrieval practice includes testing which forces students to provide the answers (i.e. Short answer and fill in the blank questions as opposed to multiple choice). More effortful retrieval also occurs with spaced and interleaved practice.
Spaced practice is testing that occurs after enough time has elapsed for some (but not complete) forgetting to occur (i.e. Present the information and then wait a couple months, days, or even just until the end of class to test students on it). Interleaved practice incorporates different but related topics and problem types, as opposed to having students practice and master one type at a time (e.g. cumulative testing where you mix problems from different units together). Interleaved practice can help students learn to focus on the underlying principles of problems and to discriminate between problem types, leading to more complex mental models and a deeper understanding of the relationships between ideas[6].

How to Implement More Assessments (Without Losing Your Mind)
So, all you have to do now is come up with a ton of quiz and test questions and free up a bunch of class time for assessments! Don’t forget you also need to grade all of these! After all, feedback is an important part of the process, and frequent (even low stakes) grading has the added benefits of enhancing student motivation, attentiveness, and attendance.I know what you busy teachers (ie. all of you) out there are thinking….“Your ”magical” teaching practice is starting to sound like a hugely effective pain in my butt.”
Don’t give up on me now though! There are some fairly simple ways to add more assessments to your curriculum. Furthermore, you should be able to do this sans student rebellion because these assessments are low-stakes. Frequent, low-stake assessments as opposed to infrequent, high-stakes assessments actually decrease student anxiety overall because no single test is a make it or break it event. In fact, several teachers have reported a large increase in positive student evaluations after restructuring their classes in this way[3],[4],[6]!

Below I lay out some tips for getting the most out of shifting your assessment practices while maintaining both your own and your students’ sanity:

1) Know that “effortful” testing is not always necessary
While effortful testing is best for retrieval practice, even basic, easily graded recognition tests such multiple choice questions still offer benefits, such as helping students remember basic (but important!) information[6],[9].

2) Create different assessment questions
You can also make assessments more effortful by creating questions that engage higher cognitive processes. Now you can sit back, relax, and indulge in one of my personal favorite pastimes (watching student brains explode) without the stressful grading!

3) Make use of educational technologies to ease your grading
For instance, clicker tests are a quick way to test students and allow you to provide feedback for the class all at once.

4) Make assessments into games
If your students need a morale boost, make a quiz into a trivia game and give winning groups candy. Some good old competition and Pavlovian conditioning may make students reassess their view of testing.

5) Assess participation
Doing something as simple as a participation grade will still provide students with incentive without overburdening them or yourself. For instance, this type of grading would work in conjunction with #3.

6) Keep graded assessments predictable
Making assessments predictable as opposed to utilizing pop quizzes helps students feel at ease.6 Furthermore, if they students KNOW an assessment is coming, they are more likely to study and pay attention.

7) Find ways to revisit old material in your assessments
Making assessments cumulative is an effective way to space out your review of material and has the added benefit of making problems interleaved and effortful, all of which maximize retrieval practice[6].

8) Have students reflect on mistakes
You can help students develop metacognitive skills by giving them opportunities to reflect upon and correct their mistakes on assessments. For instance, have students take a quiz and then discuss their answers/thinking with their classmates before receiving feedback. You can also give students opportunities to create keys to short answer questions and grade their own and several (anonymous) classmates’ answers. This will allow them to think through what makes an answer complete and effective.

9) Break large assessments into small ones
Instead of creating new assessments, break up large ones into multiple, lower-stakes assessments. For example, consider replacing big tests with several quizzes. Consider scaffolding large projects such as independent research projects and term papers. Ask for outlines, lists of references, graphs, etc. along the course of the semester before the final project is due. This might cause more work for you in the short term but can help prevent complete disasters at the end of the semester, which can be time consuming.

10) Utilize short daily or weekly quizzes
If you don’t want to adjust a big project/test or lose class time by adding time-consuming assessments, consider adding short daily or weekly quizzes. These grades can add up to equal one test grade. One could consider dropping the lowest score(s) but allowing no make ups to reduce logistical issues.
These are only a few of the many strategies one can use to transition to a frequent, low-stakes assessment system. What are your experiences with low stakes assessments? Have you made use of any which seem particularly effective in enhancing student learning?
