AAS 2016 slides from presentation entitled "Long-term, near-term, and imminent social media 'signatures' of emerging suicide death among military personnel"
What does it take to improve existing public services? Or create new ones which better address citizens’ needs? Which stakeholders need to be involved in order to have real impact? Which organisational set-up is required to create public value?
After recently visiting the ‘Politics for Tomorrow’ conference and being deeply inspired, we invited to an evening on ‘Designing services for the public’. While we discussed the basics in a meet-up two years ago, we took it a step further this time. What can we learn from international government labs for Germany? What are the pressing issues which need to be addressed? How can we as service designers contribute to this change?
Looking at examples from other parts of the world our very own Katrin Dribbisch and Martin Jordan pitched idea of running a ‘Public Service Lab’ in summer 2016 in Berlin. The event took place in the brand-new office of Fjord Berlin in Prenzlauer Berg.
Low self-esteem affects the way you see yourself, do your job, and relate with the people around you. Learn to overcome it with these quick tips.

The psychological impacts of nostalgia for people with dementiaSanda Umar
Dementia has been recognised as a significant health and social threat which is increasingly affecting individuals, families and societies. Recent conceptualizations of dementia argue that it represents an existential threat that is more than a series of technical challenges to the skill of carers. In this regard, dementia increases dependency, threatens identity and self-esteem which may ultimately lead to social isolation and compromise a person’s ability to find meaning in their life. While reminiscence therapy is frequently used with people with dementia, research findings are unclear as to whether this has any psychological benefits. With convincing evidence from experimental psychology, it may be that one of the factors determining whether reminiscence is of benefit is whether or not a nostalgic memory is evoked. Nonetheless, this has not been investigated among people with dementia. The main aim of this research is to explore the psychological impact of nostalgic memories compared to non-nostalgic memories on people affected by dementia using a randomised controlled experimental study. By investigating this, the research may be able to shed light on the way in which nostalgia buffers the psychological challenges of living with dementia. For instance, we may be able to identify more precisely how to help people with dementia maintain a psychological equilibrium, and thereby improve their quality of life and psychological wellbeing.

Abstract
Experimental, clinical and epidemiological studies have identified multiple inter-relationships of sleep with glucose regulation and metabolic disease. In one meta-analysis, after overweight and family history of diabetes, the next 7 top risk factors for incident diabetes were measures of sleep health. These included poor sleep quality, insomnia, short or extremely long sleep duration, and sleep apnea; each sleep problem was associated with incident diabetes with relative risks ranging from 1.38 to 1.74. A mechanism linking sleep apnea with diabetes is through the effects of intermittent hypoxemia on insulin sensitivity. However, studies using neurophysiological markers of sleep in healthy adults showed that selective reduction of slow wave sleep reduced glucose tolerance by 23%, thus additionally suggesting the importance neurophysiological mechanisms during sleep in glucose regulation. In support of this, longitudinal epidemiological studies demonstrated that higher proportions of slow wave sleep (N3) were protective for the development of type 2 diabetes. Recent animal and human studies also point to the effects of sleep micro-architecture—specifically the coupling of slow waves and spindles- on short-term and long-term glucose regulation, possibly through the effects on signaling between the hippocampus and hypothalamus, and changes in autonomic nervous system output. Experimental data also demonstrate a prominent role of the circadian system in regulating glucose and lipid levels. In support of those studies, epidemiological associations have identified significant associations between actigraphy-based measures of sleep irregularity (a marker of circadian disruption) with incident metabolic dysfunction and hypertension. This rich data implicating sleep disturbances as drivers of metabolic disease, coupled with data indicating a high prevalence of sleep and circadian disorders in the population, suggest novel opportunities to target sleep and circadian pathways for preventing or treating metabolic dysfunction, as well as key knowledge gaps.
The National Sleep Research Resource (NSRR; sleepdata.org) provides a large and growing repository of well-annotated polysomnograms (PSGs), actigraphy studies, and questionnaires, some associated with clinical and biochemical data relevant to understanding the links between sleep and circadian disorders with metabolic disease. Notably, the NSRR includes over 50,000 PSGs, which concurrently include multiple physiological signals with high temporal resolution, allowing generation of thousands of variables summarizing dynamic physiological changes and “cross-talk” between physiological systems...(Please see https://dknet.org/about/blog/2674 for full abstract)

Nucleophilic Addition of carbonyl compounds.pptxSSR02
Nucleophilic addition is the most important reaction of carbonyls. Not just aldehydes and ketones, but also carboxylic acid derivatives in general.
Carbonyls undergo addition reactions with a large range of nucleophiles.
Comparing the relative basicity of the nucleophile and the product is extremely helpful in determining how reversible the addition reaction is. Reactions with Grignards and hydrides are irreversible. Reactions with weak bases like halides and carboxylates generally don’t happen.
Electronic effects (inductive effects, electron donation) have a large impact on reactivity.
Large groups adjacent to the carbonyl will slow the rate of reaction.
Neutral nucleophiles can also add to carbonyls, although their additions are generally slower and more reversible. Acid catalysis is sometimes employed to increase the rate of addition.
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.
Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.
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.
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.

BREEDING METHODS FOR DISEASE RESISTANCE.pptxRASHMI M G
Plant breeding for disease resistance is a strategy to reduce crop losses caused by disease. Plants have an innate immune system that allows them to recognize pathogens and provide resistance. However, breeding for long-lasting resistance often involves combining multiple resistance genes
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.

Background
• Previous NCVS/PERSEREC/Northrop Grumman research collaboration supports the
utility of social media data to predict which military personnel will die by suicide
• In addition to knowing who will die by suicide, knowing when suicide will occur is key
• Little is known about emergent suicide risk because traditional analytic methods do
not consider nonlinear change processes or model interactions among multiple
changing variables over time
• Dynamical systems models may uncover previously unrecognized patterns

What is Dynamic System Theory (DST)?
• Assumes emergence; i.e., the many constituent parts interact to form complex relationships that cannot easily
be deduced from the individual parts
• Emergence articulates that variability in an outcome(s) is a function of three things: stable temporal patterns,
the ability to move between these stable patterns, and perturbations due to the fact that social systems are
quite large and we are only examining part of the system when we choose an outcome(s) to describe it
• Depicting models where forms of change are treated as the outcome(s) are able to simultaneously depict
temporal patterns and the stability of those patterns under an assumption of constant perturbations. We can
then characterize the system through the set of these patterns and how/when the system moves between
them, essentially mapping out emergence both descriptively and inferentially

Summary
• Results of the analysis explain an estimated 45 percent of the variance in death
• Suicides and controls show different patterns of coordination among the five domains
• “Signatures” of emerging suicide death:
– Overall: Triggers driving change in emotion and cognition
– Three months before suicide: Coupling of physiological domain with cognitive and emotional domains disappears
– One month before suicide: Coupling of behavior with cognition emerges (increased behaviors drive less change in cognition)
– One week to one day before suicide: Coupling of behavior with cognition strengthens

Editor's Notes
We decided to focus the current analyses on only those posts that were generated by the user themselves so we could model the emergence of suicide risk based solely on the information provided by the participants themselves.
In order to focus on the 12 months immediately preceding death, we excluded those data points with dates that occurred more than 365 days before the date of death. We also excluded posts with dates after the date of death to eliminate the influence of grief/memorializing from others.
We sorted the data into chronological order, and excluded any data points that violated this temporal sequence.
Because posts could occur over variable lengths of time, we weighted the difference between multiple time points. Of note, the results from the weighted analyses were similar to those obtained from unweighted analyses (i.e., ignoring the variable length of time between concurrent posts), suggesting consistency in findings regardless of how time is treated.
In the suicide group there is a consistent coupling of triggers with emotion and cognition that is often missing among controls.
When a coupling relationship occurs among controls, the direction of the arrow flows from emotion to trigger, suggesting that more intense negative emotions lead to change in triggers. In the suicide group, however, the coupling relationship flows most consistently from triggers to emotion and cognition, suggesting that more severe triggers lead to change in emotions and cognition.
Seeing a directional arrow flowing from triggers to cognition and emotion may serve as a signal for a suicide trajectory at all time points.
There is also a consistent coupling among physiology, emotion, and cognition in the suicide group. A similar coupling is observed in the suicide group only when we are more than three months out from the suicide. This means that up until 3 months prior to death, suicide cases look fairly similar to controls in this way. The loss of this coupling relationship between the 3 and 1 month pre-death point may serve as an early signal for suicide.
During the month immediately preceding death, we see the emergence of an antiphase coupling relationship between behavior and cognition in the suicide group. The arrow flows from behavior to cognition, which suggests that more maladaptive behavioral patterns leads to stabilization of the cognitive domain.
This type of coupling is absent in the control group during the same time frame. Where a coupling between behavior and cognition does exist in the control group 6 and 3 months prior to death, the direction of the arrow is reversed and the relationship is in phase vs. antiphase. This suggests that negative cognitions lead to negative behaviors in the control group.
The emergence of the antiphase coupling of behavior and cognition may serve as a near-term warning sign for suicide whereas the in-phase coupling of cognition and behavior may serve as a signature for the control group.
