Federal regulations established the following criteria that must be satisfied for the IRB to approve non-exempt research. IRB application questions are designed to obtain the information reviewers need to assess whether project plans align with these criteria.
Risks to subjects are minimized – sound scientific design, no unnecessary procedures, adequate plans to prevent harm (when possible), researchers are qualified, etc.
Risks are reasonable in relation to anticipated benefits of the research – in other words, there must be adequate scientific justification for exposing research participants to any risks associated with the study.
Subject selection is equitable – participant selection should be justified by the research question(s); not solely due to ease of access (particularly if they may be vulnerable).
The research plan includes adequate provisions to protect the privacy of subjects and to maintain confidentiality of the data collected – the IRB considers both privacy and confidentiality at all parts of the study (recruitment, during data collection, security of the data, when reporting results or sharing data, etc.).
Informed consent will be obtained from each participant prior to their inclusion in the study and in accordance with regulatory requirements , unless waived by the IRB .
Informed consent will be documented (by handwritten or electronic signature), unless this requirement is waived by the IRB. If the documentation requirement is waived, the IRB may require written information to be provided to research participants.
When appropriate, additional safeguards are in place to protect the rights and welfare of subjects who may be vulnerable to coercion or undue influence (children, educationally or economically disadvantaged, individuals with impaired decision-making capacity, prisoners, students or employees—in some cases).
When appropriate (i.e., clinical trials, high risk research, etc.), the research plan includes adequate provisions for monitoring the data collected to ensure the safety of subjects.
The growing legal use of recreational and medical cannabis has generated an increased concern for potential side effects from long-term use, particularly regarding problems with memory and sleep. Until now, the effect of cannabis use on sleep and on memory have only been studied separately. Research led by Francesca Filbey, PhD, from the Laboratory of Neuroimaging of Reward Dynamics at The University of Texas at Dallas' Center for BrainHealth ® , in collaboration with a team from the University of Amsterdam, aimed to fill this gap by testing how sleep impacts memory among cannabis users.
The study, "The role of sleep in the link between cannabis use and memory function: evidence from a cross-sectional study" was recently published in The American Journal of Drug and Alcohol Abuse .
A total of 141 adults with cannabis use disorder (CUD, defined as using cannabis regularly, more than 5 days per week during the past year) and 87 non-current users participated in this study.
Participants self-reported their frequency of sleep problems within the past week and completed a variety of cognitive assessments that tested their verbal memory, visuospatial learning and memory performance.
Results revealed that the CUD group reported more sleep problems than the non-CUD group, and that this contributed to visuospatial memory problems as well. There was no difference between the two groups in verbal memory performance.
Lead author Tracy Brown, a UT Dallas psychology PhD student in Dr. Filbey's lab, stated, "Although sleep is one of the primary reasons people use cannabis, our findings suggest that long-term cannabis use actually results in poorer sleep, which is associated with poorer memory. These findings are useful to inform the consumers, clinicians and policymakers about the therapeutic considerations for cannabis, particularly regarding its use as a sleep aid."
For researchers, this study points to the importance of analyzing sleep when evaluating the effects of cannabis on brain health." Tracy Brown, UT Dallas psychology PhD student

When you have to write a thesis or dissertation , it can be hard to know where to begin, but there are some clear steps you can follow.
The research process often begins with a very broad idea for a topic you’d like to know more about. You do some preliminary research to identify a problem . After refining your research questions , you can lay out the foundations of your research design , leading to a proposal that outlines your ideas and plans.
This article takes you through the first steps of the research process, helping you narrow down your ideas and build up a strong foundation for your research project.
Step 1: choose your topic, step 2: identify a problem, step 3: formulate research questions, step 4: create a research design, step 5: write a research proposal, other interesting articles.
First you have to come up with some ideas. Your thesis or dissertation topic can start out very broad. Think about the general area or field you’re interested in—maybe you already have specific research interests based on classes you’ve taken, or maybe you had to consider your topic when applying to graduate school and writing a statement of purpose .
Even if you already have a good sense of your topic, you’ll need to read widely to build background knowledge and begin narrowing down your ideas. Conduct an initial literature review to begin gathering relevant sources. As you read, take notes and try to identify problems, questions, debates, contradictions and gaps. Your aim is to narrow down from a broad area of interest to a specific niche.
Make sure to consider the practicalities: the requirements of your programme, the amount of time you have to complete the research, and how difficult it will be to access sources and data on the topic. Before moving onto the next stage, it’s a good idea to discuss the topic with your thesis supervisor.

So you’ve settled on a topic and found a niche—but what exactly will your research investigate, and why does it matter? To give your project focus and purpose, you have to define a research problem .
The problem might be a practical issue—for example, a process or practice that isn’t working well, an area of concern in an organization’s performance, or a difficulty faced by a specific group of people in society.
Alternatively, you might choose to investigate a theoretical problem—for example, an underexplored phenomenon or relationship, a contradiction between different models or theories, or an unresolved debate among scholars.
To put the problem in context and set your objectives, you can write a problem statement . This describes who the problem affects, why research is needed, and how your research project will contribute to solving it.
>>Read more about defining a research problem
Next, based on the problem statement, you need to write one or more research questions . These target exactly what you want to find out. They might focus on describing, comparing, evaluating, or explaining the research problem.
A strong research question should be specific enough that you can answer it thoroughly using appropriate qualitative or quantitative research methods. It should also be complex enough to require in-depth investigation, analysis, and argument. Questions that can be answered with “yes/no” or with easily available facts are not complex enough for a thesis or dissertation.
In some types of research, at this stage you might also have to develop a conceptual framework and testable hypotheses .
>>See research question examples
The research design is a practical framework for answering your research questions. It involves making decisions about the type of data you need, the methods you’ll use to collect and analyze it, and the location and timescale of your research.
There are often many possible paths you can take to answering your questions. The decisions you make will partly be based on your priorities. For example, do you want to determine causes and effects, draw generalizable conclusions, or understand the details of a specific context?
You need to decide whether you will use primary or secondary data and qualitative or quantitative methods . You also need to determine the specific tools, procedures, and materials you’ll use to collect and analyze your data, as well as your criteria for selecting participants or sources.
>>Read more about creating a research design
Finally, after completing these steps, you are ready to complete a research proposal . The proposal outlines the context, relevance, purpose, and plan of your research.
As well as outlining the background, problem statement, and research questions, the proposal should also include a literature review that shows how your project will fit into existing work on the topic. The research design section describes your approach and explains exactly what you will do.
You might have to get the proposal approved by your supervisor before you get started, and it will guide the process of writing your thesis or dissertation.

JERUSALEM — Three hundred and thirty-two days after Hersh Goldberg-Polin danced in the courtyard next to his Jerusalem synagogue on the holiday of Simchat Torah, more than a thousand people gathered there in grief and prayer to mourn his murder by Hamas terrorists in Gaza.
During the Sunday night vigil, the courtyard railings were lined with oversized yellow ribbons to symbolize advocacy for the hostages, Hapoel Jerusalem soccer flags — the 23-year-old’s favorite team — and posters that read, “We love you, stay strong, survive,” a mantra coined by his mother, Rachel Goldberg-Polin.
Just hours earlier, one of the posters had been hanging over the balcony of the home of Shira Ben-Sasson, a leader of Hakhel, the Goldberg-Polins’ egalitarian congregation in the Baka neighborhood of Jerusalem.
“We were sure we would take it down when he came home,” Ben-Sasson said.
The community wanted to unite while respecting the Goldberg-Polins’ desire for privacy, she said, prompting them to organize the prayer gathering.
“But it’s like a Band-Aid or giving first aid, it’s what you do in an emergency. I don’t know how we go on after this,” she said.
A covered courtyard at the Hakhel congregation was filled with mourners the day after Hersh Goldberg-Polin, whose family are prominent members, was found to have been killed in Gaza. Hundreds of other people crowded outside the gates, Sept. 1, 2024. (Deborah Danan)
She added that the community, which has a large contingent of English-speaking immigrants, was not prepared for the High Holidays, which begin in about a month. She said, “Seeing his empty seat is hard.”
For Ben-Sasson, who wore a T-shirt bearing the Talmudic dictum “There is no greater mitzvah than the redeeming of captives,” the tragedy is especially painful because, she said, it could have been avoided with a ceasefire agreement that freed hostages.
“Hersh was alive 48 hours ago. We think a deal could have saved him. There is no military solution to this,” she said.
That feeling of bereavement, often mixed with betrayal, pervaded gatherings across Israel on Sunday, as the country struggled with the news that six hostages who may have been freed in an agreement were now dead as negotiations continue to stall. Speakers at protests in Tel Aviv blamed Israeli Prime Minister Benjamin Netanyahu, who himself apologized for not getting the hostages out alive but blamed Hamas for obstructing a deal. The country’s labor union, the Histadrut, has called a national strike on Monday to demand a deal.
A rare early September rain lashed parts of Israel on Sunday, leading to a widespread interpretation: God, too, was weeping.
Some at the Jerusalem gathering, including the relative of another former hostage, said Netanyahu had chosen defeating Hamas over freeing the captives.

Josef Avi Yair Engel, whose grandson Ofir, 18, was released from Hamas captivity in November during that month’s ceasefire deal, expressed shock over Hersh’s murder but said he was not surprised, given the wartime policies of Netanyahu’s government.
“We knew months ago this was going to happen. Bibi’s formula, to dismantle Hamas and return the hostages, wasn’t logical. It’s an either/or situation,” Engel said, referring to Netanyahu by his nickname. “He’s tearing the country apart. I’m afraid that in the coming months there won’t be a state at all.”
Engel said he felt a close bond with Hersh’s father Jon Polin, not only because of their joint activism in the hostage families’ tent outside the Prime Minister’s Residence, but also because of their shared identity as Jerusalemites.
“There aren’t many of us in the hostage circle,” he said. “We’re like family.”
Sarah Mann, who did not know the family personally, said the weekend’s tragedy reminded her of Oct. 7.
“This day has sparks of the seventh, which created numbness and an inability to talk. Just complete shock,” she said.
Mourners left notes at a gathering at Hersh Goldberg-Polin’s family synagogue in Jerusalem. Many of the messages used the Hebrew word for “sorry.” (Deborah Danan)
Part of the reason for that, Mann said, was Rachel, who she described as a “force of faith.” Goldberg-Polin’s mother emerged as the most prominent advocate for the hostages globally and became a symbol in her own right as she crisscrossed the world calling for her son’s freedom.
“Millions of people around the world held onto her. Once that was cut, people’s ability to hold onto faith was knocked out today. But even though this has shattered us, we need to keep holding onto God,” Mann said.
For Susi Döring Preston, the day called to mind was not Oct. 7 but Yom Kippur, and its communal solemnity.
She said she usually steers clear of similar war-related events because they are too overwhelming for her.
“Before I avoided stuff like this because I guess I still had hope. But now is the time to just give in to needing to be around people because you can’t hold your own self up any more,” she said, tears rolling down her face. “You need to feel the humanity and hang onto that.”
Like so many others, Döring Preston paid tribute to the Goldberg-Polins’ tireless activism. “They needed everyone else’s strength but we drew so much strength from them and their efforts, “she said. “You felt it could change the outcome. But war is more evil than good. I think that’s the crushing thing. You can do everything right, but the outcome is still devastating.”
Guy Gordon, with his daughter Maya, added a broken heart to the piece of tape he has worn daily to mark the number of days since the hostage crisis began, Sept. 1, 2024. (Deborah Danan)
Guy Gordon, a member of Hakhel who moved to Israel from Dublin, Ireland, in the mid-1990s, said the efforts towards ensuring Hersh’s safe return have been an anchor for the community during the war. The community knew him as the family described him in its announcement of his funeral on Tuesday, as “a child of light, love and peace” who enjoyed exploring the world and coming home to his family, including his parents and younger sisters, Leebie and Orly.
“It gave us something to hope for, and pray for and to demonstrate for,” he said. “We had no choice but to be unreasonably optimistic. Tragically it transpired that he survived until the very end.”
Gordon, like many others in the crowd, wore a piece of duct tape marked with the number of days since Oct. 7 — a gesture initiated by Goldberg-Polin’s mother. Unlike on previous days, though, his tape also featured a broken red heart beside the number.
Nadia Levene, a family friend, also reflected on the improbability of Hersh’s survival.
“He did exactly what his parents begged him to do. He was strong. He did survive. And look what happened,” Levene said.
She hailed Rachel Goldberg-Polin’s “unwavering strength and belief in God,” adding, “There were times I lost faith. I suppose I was angry with God. But she just kept inspiring us all to pray, pray, pray.”
Leah Silver of Jerusalem examined stickers showing Rachel Goldberg-Polin’s mantra for her son Hersh, who was murdered in captivity in Gaza, at a gathering after Hersh’s death, Sept. 1, 2024. (Deborah Danan)
Jerusalem resident Leah Silver rejected politicizing the hostages’ deaths.
“Everything turns political so quickly. I came here because I felt that before all the protests, we need to just mourn for a moment and to pray. And show respect for each other,” she said. “We’ve become confused about who the enemy is. It’s very sad.”
But not everyone at the gathering joined in to sing Israel’s national anthem at the closing of the prayer gathering.
“I’m sorry, I can’t sing ‘Hatikvah,'” Reza Green, a Baka resident who did not know the Goldberg-Polins personally, said. “I’m too angry. We shouldn’t be here.”

45 Research Problem Examples & Inspiration. A research problem is an issue of concern that is the catalyst for your research. It demonstrates why the research problem needs to take place in the first place. Generally, you will write your research problem as a clear, concise, and focused statement that identifies an issue or gap in current ...
Research problem is a specific and well-defined issue or question that a researcher seeks to investigate through research. It is the starting point of any research project, as it sets the direction, scope, and purpose of the study. Types of Research Problems. Types of Research Problems are as follows: Descriptive problems
A research problem is a gap in existing knowledge, a contradiction in an established theory, or a real-world challenge that a researcher aims to address in their research. It is at the heart of any scientific inquiry, directing the trajectory of an investigation. The statement of a problem orients the reader to the importance of the topic, sets ...
A research problem is a specific issue or gap in existing knowledge that you aim to address in your research. You may choose to look for practical problems aimed at contributing to change, or theoretical problems aimed at expanding knowledge. Some research will do both of these things, but usually the research problem focuses on one or the other.
Step 3: Set your aims and objectives. Finally, the problem statement should frame how you intend to address the problem. Your goal here should not be to find a conclusive solution, but rather to propose more effective approaches to tackling or understanding it. The research aim is the overall purpose of your research.
From there, tally up the numbers and pick a winner. Step 4 - Craft your problem statement. Once you've selected your research problem, the final step is to craft a problem statement. Remember, your problem statement needs to be a concise outline of what the core issue is and how your study will address it.
Research may be conducted to: 1) fill such gaps in knowledge; 2) evaluate if the methodologies employed in prior studies can be adapted to solve other problems; or, 3) determine if a similar study could be conducted in a different subject area or applied in a different context or to different study sample [i.e., different setting or different ...
The research problem, therefore, is the main organizing principle guiding the analysis of your research. The problem under investigation establishes an occasion for writing and a focus that governs what you want to say. It represents the core subject matter of scholarly communication and the means by which scholars arrive at other topics of ...
While a research problem is a broad statement of the primary issue, research questions narrow down to specific queries the study seeks to answer. Techniques for Research Problem Solving:
The first question asks for a ready-made solution, and is not focused or researchable. The second question is a clearer comparative question, but note that it may not be practically feasible. For a smaller research project or thesis, it could be narrowed down further to focus on the effectiveness of drunk driving laws in just one or two countries.
The problem statement aims to highlight the pressing issue the research intends to address. It should be concise and to the point. Researchers can follow a two-step approach: first, think about the content of the problem statement, and then organize the writing framework. Before writing, clarify the following points¹:
The problem statement is a foundation of academic research writing, providing a precise representation of an existing gap or issue in a particular field of study.. Crafting a sharp and focused problem statement lays the groundwork for your research project. It highlights the research's significance.; Emphasizes its potential to influence the broader academic community.
esearch question for a study, depending on the complex-ity and breadth of your proposed work. Each question should be clear and specific, refer to the problem or phenomenon, reflect an inter. ention in experimental work, and note the target population or participants (see Figure 2.1). Identifying a research question will provide greater focus ...
Research is a procedure based on a sequence and a research problem aids in following and completing the research in a sequence. Repetition of existing literature is something that should be avoided in research. Therefore research problem in a dissertation or an essay needs to be well thought out and presented with a clear purpose.
A research problem is a clearly defined issue in a particular field of study that requires additional investigation and study to resolve. Once identified, the problem can be succinctly stated to highlight existing knowledge gaps, the importance of solving the research problem, and the difference between a current situation and an improved state.
The research problem is the questions or challenges that the proposed research is posed to answer or solve to fill the knowledge gap in existing studies or contribute to the existing knowledge body in the study area. Generally, a research problem can be referred to as a specific issue, difficulty, or challenge that a researcher or a team of researchers experiences and wants to solve in the ...

INTRODUCTION. Scientific research is usually initiated by posing evidenced-based research questions which are then explicitly restated as hypotheses.1,2 The hypotheses provide directions to guide the study, solutions, explanations, and expected results.3,4 Both research questions and hypotheses are essentially formulated based on conventional theories and real-world processes, which allow the ...
A research problem is a specific issue or gap in existing knowledge that you aim to address in your research. You may choose to look for practical problems aimed at contributing to change, or theoretical problems aimed at expanding knowledge. Some research will do both of these things, but usually the research problem focuses on one or the other.
A good research question is essential to guide your research paper, dissertation, or thesis. All research questions should be: Focused on a single problem or issue. Researchable using primary and/or secondary sources. Feasible to answer within the timeframe and practical constraints. Specific enough to answer thoroughly.
5. Select and include important variables. A clear and manageable research problem typically includes the variables that are most relevant to the study. A research team summarizes how they plan to consider and use these variables and how they might influence the results of the study. Selecting the most important variables can help the study's ...
Research may be conducted to: 1) fill such gaps in knowledge; 2) evaluate if the methodologies employed in prior studies can be adapted to solve other problems; or, 3) determine if a similar study could be conducted in a different subject area or applied to different study sample [i.e., different groups of people].
The exposure of scientific scandals and the increase of dubious research practices have generated a stream of studies on Questionable Research Practices (QRPs), such as failure to acknowledge co-authors, selective presentation of findings, or removal of data not supporting desired outcomes. In contrast to high-profile fraud cases, QRPs can be investigated using quantitative, survey-based ...
