This study investigated the reciprocal relationships between social network characteristics, social support, and mental health among older adults in the United States. The study found reciprocal associations between social support and depressive symptoms, as well as between social support and certain measures of social network structure. While social support was protective of depression, depression could undermine received support over time. The strongest link between social networks and depression was indirect, through levels of social support. Future research should focus on social support as an important pathway through which social networks impact mental health.

Whose Quality of Life is it anyway: the collective health
experience and quality of life. Paper presented to the 2011 Aging and Society: An

An individual’s perception of their discriminatory experiences has an important impact on their depressive symptoms. Some studies have shown that higher levels of perceived discrimination led to worse mental health conditions, including depressive symptoms and anxiety. Discrimination is the unfair treatment of an individual by others based on their gender, race, sexual orientation, age, and other factors. Our empirical study investigated the relationship between everyday discrimination, major lifetime discrimination, and depressive symptoms using data from 211 older African American adults in the Health among Older adults Living in Detroit (HOLD) study.
The double disadvantage hypothesis explains that individuals who are disadvantaged in one stratification are disadvantaged in other stratifications including race, gender, and other factors. We implemented this hypothesis in our investigation and found that men reported experiencing more major lifetime discriminatory experiences than women. Study results also revealed that there was a significant positive correlation between everyday discrimination and major discrimination experiences and depressive symptoms. However, gender did not moderate this relationship.
Our findings add to the existing literature by having investigated this relationship in older African American adults. Future studies should explore how various coping styles in men affect how they handle stressors, including discriminatory events. Studies should also investigate sex differences regarding how men and women process their thoughts and emotions through coping methods and seeking out social support.

DERIVATION OF MODIFIED BERNOULLI EQUATION WITH VISCOUS EFFECTS AND TERMINAL V...Wasswaderrick3
In this book, we use conservation of energy techniques on a fluid element to derive the Modified Bernoulli equation of flow with viscous or friction effects. We derive the general equation of flow/ velocity and then from this we derive the Pouiselle flow equation, the transition flow equation and the turbulent flow equation. In the situations where there are no viscous effects , the equation reduces to the Bernoulli equation. From experimental results, we are able to include other terms in the Bernoulli equation. We also look at cases where pressure gradients exist. We use the Modified Bernoulli equation to derive equations of flow rate for pipes of different cross sectional areas connected together. We also extend our techniques of energy conservation to a sphere falling in a viscous medium under the effect of gravity. We demonstrate Stokes equation of terminal velocity and turbulent flow equation. We look at a way of calculating the time taken for a body to fall in a viscous medium. We also look at the general equation of terminal velocity.
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.

Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.

Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptxMAGOTI ERNEST
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

00 Differentiating Between Network Structure and Network Function
1. RECIPROCAL RELATIONSHIP BETWEEN
SOCIAL NETWORK CHARACTERISTICS
AND MENTAL HEALTH AMONG OLDER
ADULTS IN THE UNITED STATES:
DIFFERENTIATING BETWEEN NETWORK
STRUCTURE AND NETWORK FUNCTION
BONNIE BUI
POSTDOC FELLOW, TULANE UNIVERSITY
CENTER FOR STUDIES OF DISPLACED POPULATIONS
DNAC 2019 SOCIAL NETWORKS & HEALTH WORKSHOP
2. INTRODUCTION TO THE PROBLEM
• Depression among older adults is often related to other physical health
outcomes.
• Because of increased risk for chronic conditions and functional limitations
among older adults, older adults are at increased risk for chronic
depression.
• The maintenance of social relationships is an important component of
older adult mental health.
3. INTRODUCTION TO THE PROBLEM
• Prior research have found:
• The characteristics of a network (e.g., number of ties and how supportive those ties
are) have impacts on mental health, both perceived and actual.
• Social support can buffer individuals from impacts of stressful life events (stress buffer
hypothesis).
• However, poor mental health may make maintenance of an individual’s
network difficult, compromising the ability to derive any potential benefits
from social support.
4. LITERATURE OVERVIEW
• Social Relationships and Health are linked (Berkman et al. 2000; Umberson and Montez
2010)
• Increased risk of mortality for persons with low quantity, and sometimes low quality, of social
relationships (House, Landis, and Umberson 1988)
• Socially isolated individuals are less able to buffer the impact of health stressors, putting them
at greater risk for negative health outcomes (House et al. 1988).
• Some of the ways social relationships can potentially influence health are through the
following:
• Social support (Thoits 1995)
• Social influence (Friedkin 2001)
• Social engagement (Glass et al. 2006)
• Person-to-person contact (Laumann et al. 1989)
• Access to material resources (Granovetter 1973)
5. RATIONALE FOR THE CURRENT STUDY
• In the literature, there is more attention paid to how changes in social
networks and support affect health.
• Less attention to how changes in baseline health impact changes in social
networks.
• Findings in the literature are inconsistent, which is largely due to different
ways of operationalizing networks, support, and health.
• Much of the research in the literature also sometimes conflate network
structure with social support.
6. RESEARCH GOALS
• The purpose of this research is to investigate whether there is reciprocal
(bidirectional) associations between personal/local network characteristics
and health outcomes among older adults, using various measures for
different dimensions on egocentric network structure to find which specific
network characteristics matter, and in what way.
• My focus is on conceptually distinguishing network structure and social
support by using derived egocentric network measures from roster data to
represent network structure.
7. DISTINCTION BETWEEN NUMBER AND
QUALITY OF TIES
• Social support is not an inherent part of social ties. Social ties can also be
sources of social stress that manifests itself in worsening health (Walen
and Lachman 2000).
• Social integration may be a necessary but not sufficient condition for good
health. Beyond merely being socially integrated, having supportive ties is
important for health.
• A distinction needs to be made between social integration and having supportive ties
(Berkman and Glass 2000).
10. RESEARCH QUESTIONS
• Does local network structure affect depressive symptoms for older adults?
• Does social support affect depressive symptoms for older adults?
• Do older adults’ depressive symptoms affect local network structure?
• Do older adults’ depressive symptoms affect social support?
11. DATA
• National Social Life, Health, and Aging Project (NSHAP)
• Survey uses a national area probability sample of adults born between
1920 and 1947, or ages 57 to 85 at the time of the Wave 1.
• Two waves:
• Wave 1, 3,005 interviews, 2005-2006
• Wave 2, 3,377 interviews, 2010-2011
• I only use data from adults who were re-interviewed at Wave 2 (N=2.261).
12. APPROPRIATENESS OF DATA
• Dataset is appropriate because two time points allow analysis of change in
5 years, although it is unknown whether this lag is too long when looking at
the impacts of networks on health.
• Includes detailed social network data
13. SOCIAL NETWORK ROSTER DATA
• Social Network Roster
• Respondents were asked to identify some of the people they interact with on a regular
basis and are asked the following:
• What their relationship is to each person
• Whether each person named resides in the same household
• Their gender and whether older or younger than the respondent
• Frequency of contact
• Closeness of the relationship
• Questions on instrumental support, emotional openness, and level of demands person
made on respondent
• How frequently each person named talked to others who were named
14. MEASURES
• Mental Health
• Depressive Symptoms (11-item CES-D scale)
• Network Structure
• Network size (sum of alters)
• Number living with ego
• Proportion female
• Number of close ties
• Density (ratio of actual ties to total possible ties)
• Frequency of contact with alters (summed across all alters)
15. MEASURES
• Social Support
• Perceived social support from family and friends (4-item scale)
• Demographic and Control Variables
• Age
• Indicator for female
• Indicator for white
• Indicator for college
• Cohabitation Status
16. RESEARCH METHOD
• Longitudinal analyses: conditional change method(refer to Paul Allison)
• Used to examine change in dependent variables between waves.
• Examine the relationship between an independent variable and a dependent variable
at time 2 while controlling for the effects of that dependent variable at time 1 by
including a lagged dependent variable in the model.
• Allows us to account for baseline differences between respondents.
• OLS regression to examine whether depressive symptoms, support, and
network characteristics predict changes for future depressive symptoms,
support, and networks, five years from the baseline survey.
17. IMPUTATION AND WEIGHTING
• Imputation:
• Multiple imputation with chained equations (MICE) to address missing data
• Weighting:
• “svyset” commands in Stata/SE 15.1 to adjust for nonresponse and correct for
sampling design

20. LOCAL NETWORK & SUPPORT CES-D
• Social support positively associated with later depressive symptoms.
• Density negatively associated with later depressive symptoms.
21.
22. LOCAL NETWORK & CES-D SUPPORT
• Close ties and frequency of tie activation are positively associated with
social support.
• Depressive symptoms at time 1 negatively associated with perceived
social support 5 years later.
23.
24. CES-D & SUPPORT LOCAL NETWORK
• Support at time 1 positively associated with the network size, number of
close ties, and contact with alters at time 2.
25. SUMMARY OF FINDINGS
• Reciprocal associations between social support and CES-D, as expected.
• Support is protective of depression, but depression can undermine support.
• Reciprocal associations between social support and select local network
measures (number of close ties and frequency of contact with alters).
• No reciprocal associations between CES-D and local network measures.
• Influence of local network on CES-D is largely indirect through social support.
26. • Of local network measures, only density associated with later depressive
symptoms.
• Association is positive, which is counter to the expectation that more connected
networks would be protective of mental health because of higher levels of social
support in denser networks.
• Possible explanation: Depressed individuals have fewer friends, resulting in smaller
and denser networks.
• Strongest link between local network and CES-D is social support.
• Future research should focus on social support as an important pathway in
which personal networks can impact mental health.
