Ethical Requirements in the Age of Artificial Intelligence - Supplementary material
<p><strong>Context:</strong> Software developers and users are growing concerned about the ethical use of software, especially with Artificial Intelligence (AI). In this context, we investigated how ethical requirements can be elicited and incorporated into software development. <strong>Problem</strong>: The challenge is identifying and defining effective methods for eliciting and managing ethical requirements in software development. <strong>Solution</strong>: We conducted a Systematic Literature Review (SLR) to identify techniques, methods, processes, frameworks, and tools for eliciting, analyzing, and specifying ethical requirements. <strong>IS Theory</strong>: We explore the application of theories related to requirements engineering, ethics in technology, and data governance. It focuses, in particular, on ensuring that information systems comply with ethical and legal principles from the beginning of the development cycle. <strong>Method</strong>: Following the Kitchenham and Charters protocol, we conducted an SLR with stages of planning, conducting, and reporting the results. <strong>Summarization of Results</strong>: We have identified 47 primary studies. These studies address different approaches to eliciting ethical requirements, including techniques based on user stories, analysis of ethical guidelines, specific frameworks such as ECCOLA, and methods such as interviews and modeling. <strong>Contributions and Impact on the IS area</strong>: The report contributes to the field by consolidating existing practices in the literature regarding ethical requirements. It provides a comprehensive overview of the techniques and tools available for integrating ethical considerations into software systems and identifies gaps and opportunities for future research. The study significantly impacts the IS field by providing practical and theoretical guidelines for eliciting ethical requirements in information systems.</p> <p>Supplementary material of SLR.</p>
Cognition-Associated Protein Structural Changes in a Rat Model of Aging are Related to Reduced Refolding Capacity – Peptide Quantifications
<p>Cognitive decline during aging represents a major societal burden, causing both personal and economic hardship in an increasingly aging population. There are a few well-known proteins that can misfold and aggregate in an age-dependent manner, such as amyloid β and α-synuclein. However, many studies have found that the proteostasis network, which functions to keep proteins properly folded, is impaired with age, suggesting that there may be many more proteins that incur structural alterations with age. Here, we used limited-proteolysis mass spectrometry (LiP-MS), a structural proteomic method, to globally interrogate protein conformational changes in a rat model of cognitive aging. Specifically, we compared soluble hippocampal proteins from aged rats with preserved cognition to those from aged rats with impaired cognition. We identified several hundred proteins as having undergone cognition-associated structural changes (CASCs). We report that CASC proteins are substantially more likely to be nonrefoldable than non-CASC proteins, meaning they typically cannot spontaneously refold to their native conformations after being chemically denatured. The potentially cofounding variable of post-translational modifications is systematically addressed, and we find that oxidation and phosphorylation cannot significantly explain the limited proteolysis signal. These findings suggest that noncovalent, conformational alterations may be general features in cognitive decline, and more broadly, that proteins need not form amyloids for their misfolded states to be relevant to age-related deterioration in cognitive abilities.</p> <p>This deposition provides processed peptide quantifications for all LC-MS/MS proteomics experiments conducted for this study.</p>
Inter-annual repeatability and age-dependent changes in plasma testosterone levels in a longitudinally monitored free-living passerine bird
<p>While seasonal trends in testosterone levels are known from cross-cohort studies, data on testosterone inter-annual individual repeatability in wild birds are rare. Also, our understanding of hormonal age-dependent changes in testosterone levels is limited. We assessed plasma testosterone levels in 105 samples originating from 49 repeatedly captured free-living great tits (<i>Parus major</i>) sampled during the nesting to investigate their relative long-term repeatability and within-individual changes. Furthermore, we examined the inter-annual repeatability of condition-related traits (carotenoid- and melanin-based plumage ornamentation, ptilochronological feather growth rate, body mass, and haematological heterophil/lymphocyte ratio) and their relationships to testosterone levels. We show that testosterone levels are inter-annually repeatable in females, with a non-significant pattern in males, both in absolute values and individual ranks (indicating the maintenance of relative status in a population). In males, we found a quadratic dependence of testosterone levels on age, with a peak in midlife. In contrast, female testosterone levels showed no age-dependent trends. The inter-annual repeatability of condition<span>-</span>related traits ranged from zero to moderate and was mostly unrelated to plasma testosterone concentrations. However, males with elevated testosterone had significantly higher carotenoid-pigmented yellow plumage brightness, a trait presumably involved in mating. Showing inter-annual repeatability in testosterone levels, this research opens the way to further understanding the causes of variation in condition-related traits. Based on a longitudinal dataset, this study demonstrates that male plasma testosterone undergoes age-related changes that may regulate resource allocation. Our results thus suggest that, unlike females, male birds undergo hormonal senescence similar to mammals.</p>
Combined effect of temperature, age and sex on food consumption
<p>Abiotic and biotic factors play key roles on the feeding attributes of herbivorous insects. We therefore evaluated the combined effect of temperature, age and sex on food consumption and utilization efficiencies of Parthenium biocontrol agent, <em>Zygogramma bicolorata </em>Pallister. This Mexican beetle is known as the most promising candidate for the biocontrol agent of<em> Parthenium hysterophorus </em>Linnaeus, a serious weed of wastelands, pastures and agricultural fields. </p>
Data for: Sources of CO2 produced in freshly thawed Pleistocene-age Yedoma permafrost
<p>This dataset contains δ13C and F14C compositions of CO2 samples as well as sedimentary parameters from Pleistocene Yedoma located on Kurungnakh Island in the Lena River Delta, collected during an expedition in July/August 2017.</p> <p>Sediment samples were collected from active layer soil pits, using shovels, at three sites on an active retrogressive thaw slump: Pleistocene-aged Yedoma from intact thaw mounds (TM1, TM2), intact Holocene polygonal tundra overlaying the thaw slump (HT1) and sediments from the thaw slump floor (SF3), where Pleistocene and Holocene sediments mix as a result of erosion.</p> <p>CO2 was collected in-situ from the three sites using respiration chambers, set up on vegetation-free spots on the active layer and, in fixed intervals, from a 1.5-year laboratory incubation experiment of sediment samples collected during the expedition. The analyses were performed to compare the C-isotopy of in-situ respired CO2 with that of CO2 produced during the incubation and to determine the sources of the released CO2.</p>
