Some evidence concerning the economic value of software portability: A real options approach

Software development typically involves a large capital outlay for an asset with a highly uncertain useful life. A reduction in the degree of uncertainty is likely to have a significant impact upon the expected value of an application. One method for reducing uncertainty is to incorporate modularity (e.g. a portability layer) when the application is first developed. The inclusion of such a layer involves an additional development cost. Using a real options approach we estimate the value of the flexibility that such portability confers. We use sensitivity analysis to examine the relationship between value of portability and changes in factors such as the probability that the application will have to be rewritten, expected application life, and the volatility of future redevelopment costs. Evidence is presented regarding the fundamental requirements necessary to make the additional investment in software design a positive net present value project.
KOF Working Papers

The paper aims at a joint analysis of inter-firm and intra-firm diffusion of technology, taking as an example E-selling and E-purchasing. The analysis is based on an encompassing model of diffusion, drawn from the literature, which is extended by considering technology-specific obstacles and benefits of adoption. As hypothesised, we find, firstly, that the determinants of inter-firm and intra-firm diffusion differ in case of both types of E-commerce; secondly, that the drivers of the diffusion of E-selling and E-purchasing are not the same, and, finally, that uncertainties and adjustment costs, mostly neglected in previous work, are important factors in explaining technology diffusion.
Imaging Slab Detachment Within the Western Hellenic Subduction Zone

The Western Hellenic Subduction Zone (WHSZ) has been the focus of numerous seismic investigations, but its structure, particularly between ~150‐ and 250‐km depth, remains poorly understood. Many questions exist regarding the slab geometry at these intermediate depths, including whether the slab displays any tears related to tectonic processes along the WHSZ; however, local and regional studies only provide limited depth coverage, and the coarser resolution associated with broader‐scale investigations makes it difficult to discern detailed slab structure. Here, we have employed an adaptively parameterized inversion scheme to develop a new P wave tomography model for the WHSZ that bridges the gap between regional‐ and broader‐scale studies. Our new model highlights a trench‐parallel tear in the subducting lithosphere between northern Greece and the Gulf of Corinth. Further south, the imaged velocity structure indicates that the slab is retreating to the west and that it is thinned by the southward propagating tear, but the slab has not yet detached in this area. The tear well correlates with the down‐dip limit of seismicity in central Greece, while the steeply dipping slab between ~60‐ and 200‐km depth beneath southern Greece coincides with a steeper and deeper Wadati‐Benioff zone. While the slab continues into the lower mantle, earthquakes terminate at ~200‐km depth, and this is best attributed to dehydration processes in the subducting lithosphere. The southern extent of the tear imaged in our study also coincides with volcanic centers in eastern Peloponnese. Our results suggest that the trench‐parallel tear strongly influences seismicity and volcanism throughout Greece.
Spyglass : Fast , Scalable Metadata Search for Large-Scale Storage Systems Technical Report UCSC-SSRC-0801 May 2008

As storage systems reach the petabyte scale, it has become increasingly difficult for users and storage administrator s to understand and manage their data. File metadata, such as inode and extended attributes are a valuable source of information that can aid in locating and identifying files, and can also facilitate administrative tasks, such as stora ge provisioning and recovery from backups. Unfortunately, most storage systems have no way to quickly and easily search file metadata at large scale. To address these issues, we developed Spyglass, a indexing system that efficiently gathers, indexes and queries file metadata in large-scale storage systems. Our analysis of file metadata from real-world workloads showed that metadata has spatial locality in the storage namespace and that the distribution of metadata is highly skewed. Based on these findings, we designed Spyglass to use index partitioning and signature files to quickly prune the file search space. We also developed techniques to efficiently handle index versioning, facilitating both fast update and querie s across historical indexes. Experiments on systems with up to 300 million files show that the Spyglass prototype is as much as several thousand times faster than current database solutions while requiring only a fraction of the space.
Late Cretaceous subduction-related magmatism on the southern edge of Sabzevar basin, NE Iran

Despite detailed geological studies on the Late Cretaceous Sabzevar ophiolites, the non-ophiolitic, subduction-related igneous rocks of NE Iran are still enigmatic. This paper focuses on the Late Cretaceous, non-ophiolitic Sabzevar magmatic rocks, and presents both precise U–Pb ages and a tectonomagmatic scenario for the genesis of these igneous rocks. A thick sequence of Late Cretaceous acidic volcanic rocks associated with sandstones, shales and pelagic limestones dominates the northern parts of the Lut block. This sequence is intruded by a series of shallow mafic to felsic intrusions. New zircon U–Pb results on the intrusive and extrusive rocks show ages of 75–101 Ma. These ages show a pulsed magmatism in NE Iran, which lasted for c. 25 myr. The whole-rock geochemistry of the igneous rocks shows suprasubduction-zone-related geochemical signatures, represented by negative anomalies in high field strength elements and enrichment in large ion lithophile elements. The initial 87Sr/86Sr ratios and εNd(t) values of the extrusive rocks range from 0.70411 to 0.70628 and from +5.9 to +7.4 respectively, and for intrusive rocks are in the range of 0.70423–0.70579 and +5.8 to +7.2. High εNd(t) values for these rocks confirm that their melts were derived from a depleted-mantle source. Both geochemical and isotopic data indicate that the genesis of these rocks was related to the partial melting of mid-ocean ridge basalt-type slab or depleted-mantle wedge sources during the northward movement of the Sabzevar oceanic slab beneath the southern edge of Eurasia (Turan block) in Late Cretaceous time.
Proximal algorithms for large-scale statistical modeling and optimal sensor/actuator selection

Several problems in modeling and control of stochastically-driven dynamical systems can be cast as regularized semi-deﬁnite programs. We examine two such representative problems and show that they can be formulated in a similar manner. The ﬁrst, in statistical modeling, seeks to reconcile observed statistics by suitably and minimally perturbing prior dynamics. The second, seeks to optimally select sensors and actuators for control purposes. To address modeling and control of large-scale systems we develop a uniﬁed algorithmic framework using proximal methods. Our customized algorithms exploit problem structure and allow handling statistical modeling, as well as sensor and actuator selection, for substantially larger scales than what is amenable to current general-purpose solvers.
Highlighting interlinkages between sustainable diets and sustainable food systems.

Abstract Sustainable food systems and sustainable diets are increasingly being called upon as ways to orient action towards the eradication of hunger and malnutrition and the fulfilment of the sustainable development goals. This chapter explores the links between the two notions and how these links can orient policies and consumption choices. To do so, it first considers the relationships between food systems and diets, how food systems condition the availability and accessibility of foods that can be part of a diet, and also how demand determines the foods that are made available and accessible. Diets are thus both the results and the drivers of food systems. A sustainable food system can be defined as a food system that ensures food security and nutrition for all in such a way that the economic, social and environmental bases to generate food security and nutrition of future generations are not compromised. The concept of a sustainable diet combines two totally different perspectives: (i) a nutrition perspective, which is person focused; and (ii) a global sustainability perspective, in all its dimensions - environmental, economic and social. Understanding the links between these two notions can help design policies and incentives to improve the sustainability of food systems and diets, building upon the motivation of various actors, consumers and private actors, which are often related to very different dimensions (health, environment, social and cultural).
The effect of classical foot massage on insomnia and anxiety in preeclamptic pregnant women: a randomized controlled study

SUMMARY OBJECTIVE: Preeclampsia is one of the most common complaints during pregnancy. Preeclamptic pregnant women may experience insomnia and anxiety. METHODS: This study was a randomized controlled trial with 71 preeclamptic women. In the experimental group, a foot massage was done for 3 days in a week. In the control group, any applications were not done. These groups were assessed for insomnia and anxiety levels. RESULTS: In this study, it was found that classical foot massage significantly reduced (12.45±5.74 vs. 33.4±6.41) insomnia and anxiety compared with the control group (18.8±6.44 vs. 39.19±8.31, respectively, p<0.05). CONCLUSION: The classical foot massage can effectively decrease insomnia and anxiety symptoms.
“It’s no use saying it in English”: A qualitative study exploring community leaders’ perceptions of the challenges and opportunities with translating and interpreting COVID-19 related public health messaging to reach ethnic minorities in Australia

Background The Australian Government implemented a range of public health response strategies and communication approaches to reduce the spread of COVID-19; however, concerns have been raised around a failure to sufficiently consider culturally and linguistically diverse (CaLD) communities in these processes. This research aimed to understand the factors that have impacted COVID-19 communication and engagement efforts during the pandemic from the perspective of key CaLD community and faith-based leaders. A further aim was to understand the processes that could be adopted to support future communication strategies, including promoting pandemic-related vaccines. Approach This study included 29 key informant interviews with community and faith-based leaders in New South Wales, Australia. Results The overwhelming message from community leaders was a sense of shared responsibility between their organisations and governments in communicating pertinent and accurate COVID-19 related information to CaLD communities. They expressed a sense of duty to keep their community members safe. However, community leaders and others shouldered significant costs related to resources and time that need to be acknowledged by governments in preparing for future disease outbreaks. They felt that governments should consider: 1) improving communication between governments and CaLD organisations; 2) responding to the specific CaLD needs with greater agility; 3) foregrounding social media in their communication strategy; 4) reinvesting in local public health units to know their population; 5) developing a health ambassadors model program; 6) preparing a hybrid model of translators/interpreters to fill the gap; and, 7) reimagining vaccine information campaigns to target CaLD communities better. Conclusion Given the technical details about the COVID-19 virus conveyed in government information campaigns and the media, ensuring the most vulnerable populations, including people from CaLD backgrounds, access clear, concise and timely public health messaging from governments and community organisations requires further attention.
Changes in caregiving risk and motor function among older adults participating in community gatherings in Koshigaya city

[Purpose] This study investigated the changes in caregiving risk and motor function among older adults participating in community gatherings (“Kayoinoba”) in Koshigaya. [Participants and Methods] A total of 257 older participants who engaged in the Kayoinoba program for 6 months from its inception were included in the analysis. Caregiving risk and motor function were assessed twice—once at the beginning of the Kayoinoba (first assessment) and again 6 months later (second assessment). The Kihon Checklist was used to evaluate caregiving risk, and the timed up-and-go, one-leg standing, and 30-s chair-stand tests were done to evaluate motor functioning. Participants were divided into pre-frail and healthy groups, and the first and second assessments were compared. [Results] The Kihon Checklist score of the pre-frail group significantly improved from the first to the second assessment. The pre-frail group had lower composite scores for physical function, outdoor activities, and depression mood items based on the Kihon Checklist; the healthy group showed no such differences. Performance on the 30-s chair-stand test was significantly better in the second assessment than in the first assessment in both groups. [Conclusion] The findings of this study emphasize the benefits of participating in Kayoinoba among high-risk older adults and provide the knowledge for developing a healthier community-based symbiotic society.
Unravelling the skills of data scientists: A text mining analysis of Dutch university master programs in data science and artificial intelligence

The growing demand for data scientists in both the global and Dutch labour markets has led to an increase in data science and artificial intelligence (AI) master programs offered by universities. However, there is still a lack of clarity regarding the specific skills of data scientists. This study addresses this issue by employing Correlated Topic Modeling (CTM) to analyse the content of 41 master programs offered by 11 Dutch universities and an interuniversity combined program. We assess the differences and similarities in the core skills taught by these programs, determine the subject-specific and general nature of the skills, and provide a comparison between the different types of universities offering these programs. Our analysis reveals that data processing, statistics, research, and ethics are the core competencies in Dutch data science and AI master programs. General universities tend to focus on research skills, while technical universities lean more towards IT and electronics skills. Broad-focussed data science and AI programs generally concentrate on data processing, information technology, electronics, and research, while subject-specific programs give priority to statistics and ethics. This research enhances the understanding of the diverse skills of Dutch data science graduates, providing valuable insights for employers, academic institutions, and prospective students.
PIEZO1 is a distal nephron mechanosensor and is required for flow-induced K+ secretion

Ca2+-activated BK channels in renal intercalated cells (ICs) mediate luminal flow–induced K+ secretion (FIKS), but how ICs sense increased flow remains uncertain. We examined whether PIEZO1, a mechanosensitive Ca2+-permeable channel expressed in the basolateral membranes of ICs, is required for FIKS. In isolated cortical collecting ducts (CCDs), the mechanosensitive cation-selective channel inhibitor GsMTx4 dampened flow-induced increases in intracellular Ca2+ concentration ([Ca2+]i), whereas the PIEZO1 activator Yoda1 increased [Ca2+]i and BK channel activity. CCDs from mice fed a high-K+ (HK) diet exhibited a greater Yoda1-dependent increase in [Ca2+]i than CCDs from mice fed a control K+ diet. ICs in CCDs isolated from mice with a targeted gene deletion of Piezo1 in ICs (IC-Piezo1-KO) exhibited a blunted [Ca2+]i response to Yoda1 or increased flow, with an associated loss of FIKS in CCDs. Male IC-Piezo1-KO mice selectively exhibited an increased blood [K+] in response to an oral K+ bolus and blunted urinary K+ excretion following a volume challenge. Whole-cell expression of BKα subunit was reduced in ICs of IC-Piezo1-KO mice fed an HK diet. We conclude that PIEZO1 mediates flow-induced basolateral Ca2+ entry into ICs, is upregulated in the CCD in response to an HK diet, and is necessary for FIKS.
A Dynamic Foundation: Aberrations of Sleep Architecture and Its Association With Clinical and Sub-clinical Psychopathology

This investigation centered on the hypnagogic and hypnopompic wake-sleep/sleep-wake transition states and the associated exploration of hypnagogic and hypnopompic experiences (HHEs), and sleep paralysis (SP) on psychiatric exacerbation and paradoxical masking. The study aims to discern causality by examining how these sleep-related experiences may contribute to the emergence or exacerbation of psychiatric and neurodegenerative conditions, particularly, pertaining to the clinical or sub-clinical demographic of Schizotypal Personality Disorder (STPD), Mood Disorders, Schizophrenia, Post-Traumatic Stress Disorder (PTSD), Generalized Anxiety Disorder (GAD), Narcolepsy, Panic Disorder, specific phobias, or heightened psychotic sensitivity. Methodologically, this study employed a comprehensive literature review, drawing from a range of studies across sleep medicine, psychiatry, and psychology, utilizing PubMed-indexed peer-reviewed scientific literature, sourcing from academic institutions, Google Scholar, and open-access publications. This interdisciplinary approach allowed for a nuanced and systematic understanding of the potential links between specific sleep-wake/wake-sleep aberrations and their masking or exacerbation of clinical/sub-clinical psychiatric symptomatology in this particular demographic. Insights gained from the outcome of this study hold promise for advancing understanding of the interrelationship between sleep neurobiology and psychiatric disorders. Additionally, the findings may inform targeted therapeutic interventions tailored to mitigate the impact of sleep-wake disruptions on vulnerable populations. The overarching objective is to bridge current gaps in knowledge, cultivating a more profound understanding with direct implications for both clinical practice and ongoing research endeavors. The study outcomes provide an intriguing understanding of the complex relationship between sleep neurobiology and psychiatric disorders, paving the way for targeted therapeutic interventions to alleviate the effects of sleep-wake disruptions, and addressing critical gaps in knowledge with direct implications for clinical practice and ongoing research.
Evaluating the Role of Methylated Circulating Tumor DNA in Combination With Pathological Prognostic Factors for Predicting Recurrence of Colorectal Cancer

Background: Colorectal cancer (CRC) has a high rate of recurrence, in particular for advanced disease, but prognosis based on staging and pathology at surgery can have limited efficacy. The presence of circulating tumor DNA (ctDNA) at diagnosis could be used to improve the prediction for disease recurrence. Objectives: To assess the impact of detecting methylated BCAT1/IKZF1 ctDNA at diagnosis in combination with demographic, lifestyle, clinical factors and tumor pathology, to assess predictive value for recurrence. Design: A retrospective cohort study. Methods: The cohort included 180 patients (36 with recurrent CRC), who had undergone complete treatment and surveillance for a minimum of 3 years. Participant clinical details and ctDNA methylated BCAT1/IKZF1 results were compared between those with and without recurrence, and cox regression analysis assessed each factor on disease-free survival. Results: Clinical factors independently associated with reduced disease-free survival included nodal involvement (HR = 3.83, 95% CI 1.56-9.43, P = .003), M1 stage (HR = 4.41, 95% CI 1.18-16.45, P = .027), a resection margin less than 2 mm (HR = 4.60, 95% CI 1.19-17.76, P = .027), perineural involvement (HR = 2.50, 95% CI 1.01-6.17, P = .047) and distal tumors (HR = 3.13, 95% CI 1.07-9.18, P = .037). Methylated BCAT1/IKZF1 was detected in 51.7% (93/180) of pre-treatment plasma samples. When a positive ctDNA finding was considered in combination with these clinical prognostic factors, there was improved predictive power of recurrence for patients with perineural involvement (HR = 4.44, 95% CI 1.92-10.26, P < .001), and it marginally improved the predictive factor for M1 stage (HR = 7.59, 95% CI 2.30-25.07, P = .001) and distal tumors (HR = 5.04, 95% CI 1.88-13.49, P = .001). Conclusions: Nodal invasion, metastatic disease, distal tumor site, low resection margins and perineural invasion were associated with disease recurrence. Pre-treatment methylated ctDNA measurement can improve the predictive value for recurrence in a subset of patients, particularly those with perineural involvement.
