This document defines key concepts in developing theoretical and conceptual frameworks for research. It discusses the definitions and types of theories, conceptual models, and variables. It also describes the purpose of a theoretical framework and how it guides research. Key elements that must be defined for a study are identified, such as the independent, dependent, and intervening variables through operational definitions. The differences between quantitative and qualitative research questions and purpose statements are also outlined.

Social safety nets in Bangladesh have been quite effective in smoothing the consumption and the income of poor households and helping them cope with stresses and shocks. These programs, however, cover only a fraction of the poor, and they must be strengthened if they are to adequately address poverty or mitigate the vulnerability to poverty in a sustainable way. Safety nets will become even more important in Bangladesh as the country faces economic downturn, food price fluctuations, climate change, and other developments that increase the vulnerability of the poor.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
Securing your Kubernetes cluster_ a step-by-step guide to success !
Research developing theoretical and conceptual frameworks
1. DEVELOPING THEORETICAL AND CONCEPTUAL FRAMEWORKS
M. Dablo- Dec.14, 11
Theory- fr Greek- theorem; proposition to be proved
- Set of related statements that describe or explain phenomena in a systematic way
- A broad abstract characterization of phenomena. A generalization that presents a systematic
explanation about the relationships among phenomena. Its writings include terms such as
proposition, postulate, premise, axiom, law, principle
- A set of interrelated constructs (concepts), definitions, and propositions that present a
systematic view of phenomena by specifying relations among variables, with the purpose of
explaining and predicting the phenomena
- It is a statements of relationship between two variables, one acting as the independent variable,
another as the dependent variable
- Examples: Theory of Planned Behaviour
o Proposition: behaviour that is volitional is determined by people’s intention to perform
the behaviour. Intention to perform or not perform behaviour is determined by 3
factors: attitudes toward the behaviour, subjective norms, and perceive self-control.
The relative importance of the 3 factors in influencing intention varies across behaviours
and situations.
Types of theories:
1. Descriptive- describes or presents a phenomenon. It explains why an event is associated with
another event or what causes an event to happen
2. Grand theory (Macrotheory)- describes the large segments of the human experience
3. Middle-range theory- more specific to certain phenomena
4. Borrowed- non-nursing models used by nurse researchers
5. Shared- when the appropriateness of a borrowed theory for nursing is confirmed
6. Grounded- data-driven explanations that account for the phenomena under study through
inductive processes
Objective of a theory
Distinct features of theory:
1. Concept- the building block of theory; a word picture or mental idea of a phenomenon, and a
word or term that symbolizes certain aspect of reality
- Concrete: the human brain; abstract: intelligence
2. Construct- used to specify a phenomenon or a situation that cannot be directly observed but
needs to be inferred by certain concrete or less abstract indicators of phenomenon. It can be
ascertained only by using certain observable and measureable procedures
- Construct: physical health; inferred: assessment
2. 3. Proposition- a statement or assertion of a relationship between concepts
- Theories or generalizations founded on empirical data are sources of propositional statements
What is a theoretical framework- it presents a theory that explains why a problem under study exists
and explains the connection between certain factors and the problem
- Concepts presented are usually abstract and expressed in general terms
Functions of theoretical framework in research:
- It provides the general framework which can guide the data analysis
- It identifies the variable to be measures
- It explains why one variable can possibly affect another or why the independent variable can
possibly influence the dependent variable
- It limits the scope of data relevant to the framework by focusing on specific variables
- It stipulates ..in analyzing and interpreting data
- Not all research studies need a theoretical framework, but correlational and casual studies do.
Conceptual models (conceptual frameworks or conceptual schemes)
- Represents a less formal attempt in organizing phenomena than theories. It deals with
abstractions (concepts) that are assembled by virtue of their relevance to a common theme
- It broadly presents understanding of the phenomenon of interest and reflects the assumptions
and philosophic views of the model’s designer
- Example: Orem’s self-care model, Swanson’s theory of caring
Schematic and statistical models-
- Schematic models- are common in both qualitative and quantitative research, represent
phenomena graphically
- Statistical model- are playing a growing role in quantitative studies. Use symbols to express
quantitatively the nature of relationships among variables. Few relationships in the behavioural
sciences.
3. CONCEPTUALIZING THE RESEARCH STUDY
Statement of purpose: or purpose statement, summary of overall goal
- The title itself is the objective/purpose
- Purpose statements: a declarative statement that advances the overall direction or focus for the
study
- Research questions: interrogative statements that narrow the purpose statement to specific
questions that researchers seek to answer in their study
- Research hypotheses: declarative statements in quantitative research in which the investigator
makes a prediction or conjecture about the outcomes relationship
- Research objective: a statement of intent for the study that specifies specific goals that the
investigator plans to achieve in a study
Purpose Research Hypothesis Research
statement questions objectives
Intent Overall direction Raise ?s that are Make predictions State goals

expectations

Differences between quantitative and qualitative purpose statements and research questions
Quantitative- more closed ended
1. Probable cause/effect- why did it happen?
2. Use of theories- why did it happen in view of an explanation or theory?
3. Assessing differences and magnitude
- How much happened?
- How many times did it happen?
- What were the differences among groups in what happened?
Qualitative- more open-ended
1. Descriptive- what happened?
2. Interpretive- what was the meaning to people of what happened?
3. Process-oriented- what happened over time?
Variables (concepts)
- A concept that stands for a variation within a class of objects or persons
4. - A characteristic or property that can take different values or attributes
- These are central building blocks of quantitative studies
- Ex: weight, anxiety levels, income, etc.
Types of variables:
1. Dependent variable- is the “assumed effect” of another variable
- The change that occurs in the study population when one or more factors are changed or when
an interventions is introduced
- Sometimes the dependent variable is the problem itself
2. Independent- the “assumed cause” of a problem
- Ex: The relationship between exposure to mass media and smoking habits among young adults”
independent: Exposure to mass media (what is the level of exposure to mass media among
young adults); dependent: smoking habits (what is the level of smoking habits among young
adults?)
- Assumed reason for any “change” or variation in the dependent variable
3. Intervening- is a factor that works “between” the independent and dependent variable
- It can weaken (decrease) or strengthen (increase) the effect of the independent on the
dependent variables
- Also called a “facilitating variable”, “moderator” or a control variable
- Ex: Knowledge on the dangers of smoking, attitudes towards life, and smoking habits of young
professionals independent: knowledge on the dangers of smoking; Intervening: attitudes
towards life; dependent: smoking habits
4. Antecedent- is a factor or characteristic which is found before the independent variable
- Expected to influence the independent variable/s, usually irreversible
- Ex: extent of exposure to print media and reading ability of college freshmen antecedent:
gender, residence, parent’s education; independent: extent of exposure to print media;
dependent: reading ability
Examples:
1. Unmarried pregnant teenagers report a less positive body image than do married pregnant
teenagers
Independent: marital status
Dependent: body image
2. There is an inverse relationship between postoperative hysterectomy patients’ anxiety levels
and their requests for pain medication
IV: anxiety
DV: requests pain medications
3. Older adults demonstrate a lower self-image after retirement than before retirement.
IV: retirement
DV: self-image
5. Operational definition of variables:
- Gives a specific meaning to the variable. It clarifies how a variable is used and measured in the
study
- A variable must be defined in terms of events/units of measurement that are observable by the
senses
Establishing categories of variables
1. Mutually exclusive categories- do not overlap when a respondent cannot be assigned to more
than one category.
- Define terms as how it is being used in your study
2. Exhausative categories
What is a research design?
- It is the researcher’s overall plan for answering the research question
- It is the blue print of the study. It guides the collection, measurement and analysis of data
- It is a plan or course of action which the researcher follows in order to answer the research
question/s or solve the research problem.
