Database memory forensics: A machine learning approach to reverse-engineer query activity

Memory analysis allows forensic investigators to establish a more complete timeline of system activity using a snapshot of main memory (i.e., RAM). Investigators may rely on such analysis to detect malicious activity and understand the scope of what data was exfiltrated. This is of particular interest in the presence of incomplete or untrusted logs, where a privileged user (or an attacker with such capabilities) can altogether bypass or disable logging. In such instances, a forensic investigator can still rely on the fact that data must ultimately be processed in memory, regardless of the information that is recorded in audit logs.In this work, we propose methods to reverse-engineer query activity from a database management system (DBMS) process snapshot. Since DBMSes are used to manage and store an organization's most sensitive data, they are of particular concern for data exfiltration. A DBMS processes queries using a series of operations, such as index sort, file sort, or joins, which produce their own set of distinct forensic artifacts in memory. Our methods use these artifacts to make conclusions about recent query activity even in the presence of untrusted or incomplete logs. Our methods use a supervised learning based model using support vector machines (SVM) to approximate recently executed queries given these memory artifacts. We extract feature vectors from the byte frequencies in a special area of the DBMS process called the sort area fragment, and use SVM to predict the type of the query operation under supervised learning. We demonstrate the capabilities and the accuracy of our methods for two representative DBMSes, PostgreSQL and MySQL. Experimental results show that, our model achieved an accuracy of 92% and 90% on MySQL and PostgreSQL datasets, respectively.

‘Go on keep going’: The instruction of sustained embodied activities

This study investigates the instruction of sustained embodied activities, that is, activities that require a continuous, sustained embodied effort. The context is horse-riding lessons. Riding instructors are shown to teach sustained embodied activities in orientation to four temporalities. Most fundamentally, they co-construct these activities as an ongoing and continuing timeline, for example, by giving action-continuing directives and by projecting continuation prosodically. In addition, instructors attend to the temporal organization of individual component actions of the activity. They situate actions in the past, present, or future along the timeline of the sustained activity; they co-construct the duration of individual actions as flexible; and they orient to individual actions as brief and transient. The analysis reveals practices that do not initiate or respond to specific actions but that accompany an activity as such, treating progression itself as a target for instruction and calling into question the often-assumed sequential adjacency of action pairs.

Zadužbina - integrativni višemedijski pristup istraživanju srpske srednjevekovne kulture na ranom školskom uzrastu

This paper will present the process and the results of the work on the "Endowment" project, which was realized in cooperation with the Association for Creative Development of Children "Creative Laboratory" and the Eureka Children's Club during 2022-2023. in Kruševac. The goal of the project was to develop a positive image of oneself and one's spiritual identity, to gain knowledge about our roots and origins, to learn about the importance of medieval culture for the spiritual identity of the Serbian people, to which the children themselves belong. Program contents are devoted to endowments, rulers, saints, historical events and the overall culture of medieval Serbia. 25 children aged 7-11 participated in the project for 10 weeks. As an occasion, provocation and inspiration for research, we used a visit to the Park of Miniatures in Bagdala, where models of our medieval monasteries were placed. The results of the work were presented at the ceremonial academy called "Endowment", which was designed as a three-component unit and, with the blessing of His Eminence, the Bishop of Kruševac Mr. David, was held in the amphitheater of the Lazarica Church in Kruševac in February 2023. The first component consisted of a photo exhibition entitled "Trace of our past" which represents a timeline of children's research activities, the second, an art exhibition of children's works "Mosaic of our past" and the third stage performance "Endowment".By interviewing all participants, qualitative analysis of the process and results of the work, we concluded that the multimedia, integrative and project approach had an effect on raising the interest and self-confidence of children, mobilized their attention and contributed to the development of awareness and knowledge about their spiritual origin and cultural identity.

Towards Personalization of Student Learning and Engagement in a First-Year Undergraduate Course

Advancements in classroom technology and data collection have allowed for new studies into how students interact with course material. This paper presents the development of a new tool designed to process timestamp information from a learning management system in a remote, synchronous course to analyze patterns of behaviour and predict student outcomes in the course. The timestamps are arranged to create a personalized timeline of activity for individual students, focusing on the length of time between successive interactions. Preliminary analysis of the timestamp intervals across a class of students over an entire term is also presented. The lengths of time between successive course interactions follows a long-tail distribution with peaks occurring at approximately 24-hour periods, implying that students were most likely to access course material at daily or multi-day intervals.

Heart Rate Variability in Huntington Disease: A Long-Term Longitudinal Study

Introduction: The aim of the study was to follow tonic and phasic autonomic nervous activity in Huntington disease (HD) mutation carriers and patients. Methods: Evaluation of motor functions and total functional capacity was performed in 30 HD mutation carriers or patients at the beginning and in 22 subjects after 8–10 years. Continuous arterial blood pressure, heart rate (HR), and ECG at rest were measured, and HR variability analysis was performed in four different ways. A group of matched controls was also evaluated. Results: Eighteen subjects were assorted in 3 groups: 6 HD mutation carriers without motor symptoms (PHD) who remained so (PHD-PHD); 6 early symptomatic patients (EHD) who remained so (EHD-EHD); and 6 early symptomatic patients who deteriorated to a late symptomatic (LHD) (EHD-LHD). At the beginning, sympathetic tonic activity in PHD was elevated, according to mean arterial pressure (99 ± 10.6 mm Hg) higher than in controls (85 ± 8.7 mm Hg) and EHD (82 ± 9.9 mm Hg) (Dunnett’s test, p < 0.05) and higher HR (78 ± 16 beats/min) than after 8–10 years (64 ± 11.3 beats/min) (paired t test, p < 0.05). There was also a decreased phasic sympathetic activity in EHD patients compared controls at the beginning (219 ± 106 vs. 664 ± 466 s²/Hz) and after 8–10 years (182 ± 136 vs. 1,012 ± 1,369 s²/Hz) (Dunnett’s test, p < 0.05). In patients who deteriorated from EHD to LHD, there was a drop in phasic parasympathetic activity from 887 ± 433 to 230 ± 235 s²/Hz (paired t test, p < 0.05). Conclusions: Our long-term observational study provides important information on the timeline of ANS activity in HD progress. There was a temporary increase in cardiac and vascular sympathetic activity in PHD subjects. The normalization of HR in PHD subjects might indicate the approach of an outbreak of clinical disease phase.

Timelines to initiate a phase III trial across the globe: a sub-analysis of the APHINITY trial.

BackgroundGeographic location and national income may influence access to innovation in healthcare. We aimed to study if geographical location and national income influenced the timelines to activate the global phase III APHINITY trial, evaluating adjuvant pertuzumab in patients with HER2-positive early breast cancer.MethodsTime from regulatory authority (RA) submission to approval (RAA), time to Ethics Committee/Institutional Review Board (EC/IRB) approval, time from study approval by EC/IRB to first randomised patient and from first to last randomised patient were collected. Analyses were conducted grouping countries by geographical region or economic income classification.ResultsForty-one countries (of 42) had data available regarding all relevant timelines. No statistical difference was observed between the time to RAA and geographical region (p = 0.47), although there was a trend to longer time to RAA in upper middle-income economies (p = 0.07). Except for time from first to last patient randomised, there was wide variation in timelines overall and within geographical regions and economic income groups.ConclusionsGeographical location and income classification did not appear to be the major drivers influencing time for clinical trial activation. Wide variability in activation timelines within geographical regions and income groups exists and is worthy of further investigation.

Feedback from neurology residents and neuroimmunology fellows about the practical training in multiple sclerosis

ObjectiveTo obtain feedback from Neurology residents and Neuroimmunology fellows about the practical training in multiple sclerosis (MS). MethodsA survey was developed and administered electronically to Neurology residents or Neuroimmunology fellows that received training in eight large MS outpatient clinics in Brazil, from 2018 to 2021. We evaluated their beliefs on: (1) the optimal number of MS patients evaluated in a 4-hour outpatient clinic session, (2) the quality of dedicated MS medical records, (3) the training of the neurological exam in MS patients, (4) the teaching discussion with the attending neuroimmunologist and (5) the prescription of MS disease-modifying drugs (DMDs). ResultsThe response rate was 57% (43/76). We found that 4 or 5 MS patients would be optimal during a 4-hour outpatient clinic session. Optimal MS medical records were considered structured and presented in a timeline of disease activity and the history of DMDs. 18 in 43 (42%) respondents felt insecure in performing clinical scales used in MS patients. Discussion with the attending neurologist specialized in Neuroimmunology was considered adequate in only half of the respondents, suggesting a need for improvement in teaching strategies. Almost a quarter of the respondents (11/43, 26%) felt that the prescription of DMDs was complex and challenging. Some respondents suggested that readymade templates could be helpful. ConclusionThe number of patients, medical records, use of MS clinical scales, discussion with attending neurologist specialized in MS care, and the prescription of DMDs present room for improvement in MS training for Neurology residents and Neuroimmunology fellows.

A Smartphone Application to Assess Real-Time and Individual-Specific Societal Participation: A Development and Usability Study

ObjectiveTo develop a mobile health app to assess individual-specific meaningful societal participation in real time and to evaluate its usability. DesignDevelopment and usability study. SettingGeneral community. ParticipantsPersons with multiple sclerosis (PwMS) utilized the app for 7 consecutive days. In total, 72 PwMS and smartphone owners were included in the analysis (N=72). InterventionsUsing location tracking, the newly developed Whereabouts app generates an individual-specific timeline of societal participation activities each day, consisting of location and transportation intervals. Subsequently, this timeline is real time enriched by the user with self-reported ratings of meaningfulness and perceived strain of these societal participation activities. The app is based on the International Classification of Functioning, Disability and Health and was developed in an iterative process. Main Outcome Measure(s)Usability of the newly developed Whereabouts app was evaluated by analyzing the effectiveness, efficiency, and user satisfaction. ResultsRegarding effectiveness, the app correctly assessed the type, frequency, and duration of different societal participation activities for 96.1% of the participation activities. The self-reported ratings of societal participation varied for meaningfulness (range, 5-8), perceived strain (range, 2-6), and meaningfulness of the perceived strain (range, 5-8). The latter 2 were highly correlated (r=0.857). With regards to efficiency, 3.9% of the generated participation activities had to be excluded due to inaccuracy or incompleteness. Relating to user satisfaction, 57.3% of PwMS reported that they were satisfied with the usability of the app and 59.7% stated that it gave a realistic overview of their daily activities. However, 54.4% PwMS missed the possibility to specify activities at home, to add activities in more detail, and to correct mistakes. ConclusionsThe Whereabouts app demonstrates usability in assessing real-time, individual-specific meaningful societal participation. Improvements are recommended, such as the possibility to specify participation activities and to generate a graphic overview.

ERANET JTC 2011: Submission and Activation of an International Academic Translational Project in Advanced Breast Cancer. Experience From the ET-FES Study.

Background: Academic research is important to face unmet medical needs. The Oncological community encounters many hurdles in setting up multicenter investigator-driven trials mainly due to administrative complexity. The purpose of a network organization at a multinational level is to facilitate clinical trials through standardization, coordination, and education for drug development and regulatory approval.Methods: The application of an European grant foresees the creation of a consortium which aims at facilitating multi-center academic clinical trials.Results: The ERA-NET TRANSCAN Call 2011 on “Validation of biomarkers for personalized cancer medicine” was released on December 2011. This project included Italian, Spanish, French and German centers. The approval process included Consortium constitution, project submission, Clinical Trial Submission, and activation on a national level. The different timescales for submitting study documents in each Country and the misalignment of objections by each Competent Authority CA, generated several requests for changes to the study documents which meant amendments had to be made; as requested by the 2001/20/EC Directive, the alignment of core documents is mandatory. This procedure impacted significantly on study activation timelines. Time to first patient in was 14, 10, 28, and 31 months from the date of submission in Italy, France, Spain, and Germany, respectively. Accrual was stopped on 22nd January 2021 due to an 18F FES shortage as the primary reason but also for having exceeded the project deadlines with consequent exhaustion of the funds allocated for the project.Conclusions: Pharmaceutical companies might be reluctant to fund research projects aimed at treatment individualization if the approval for a wider indication has already been achieved. Academic trials therefore become fundamental for promoting trials which are not attractive to big pharma. It was very difficult and time consuming to activate an academic clinical trial, for this reason, a study may become “old” as new drugs entered into the market. National institutions should promote the development of clinical research infrastructures and network with competence in regulatory, ethical, and legal skills to speed up academic research.

Social Media Marketing as a Branding Strategy in Extraordinary Times: Lessons from the COVID-19 Pandemic

This review expands our insight into the ways the required adaptation to digital channels caused by COVID-19 has affected the creation of brand equity through social media marketing. Based on a systematic literature review, we propose a conceptual framework that answers the following research question: How can businesses, amidst and after the COVID-19 pandemic, adapt their social media marketing strategy to create positive brand equity? The conceptual framework describes four components as the basis for a potential social media marketing strategy. First, (1) businesses need to develop a clear perspective on their current social media marketing activities, and (2) evaluate current branding elements. Based on this, (3) the timeline of marketing activities must be postponed or adapted to the needs of consumers. Lastly, (4) businesses must adapt their messaging to show empathy and deliver relevant information. Within this process, governmental parties, financial institutions, influencers, and consumers are identified as stakeholders who influence and assist businesses in optimizing their social media marketing strategy. These findings are relevant for academics and businesses to further understand the long-term effects of COVID-19 on social media marketing. Additionally, they highlight that the roles of online channels and the consumer are expanding in the future.

To sell, or not to sell: social media data-breach in second-hand Android devices

PurposeThe purpose of this paper is to investigate the private-data pertaining to the interaction of users with social media applications that can be recovered from second-hand Android devices.Design/methodology/approachThis study uses a black-box testing-principles based methodology to develop use-cases that simulate real-world case-scenarios of the activities performed by the users on the social media application. The authors executed these use-cases in a controlled experiment and examined the Android smartphone to recover the private-data pertaining to these use-cases.FindingsThe results suggest that the social media data recovered from Android devices can reveal a complete timeline of activities performed by the user, identify all the videos watched, uploaded, shared and deleted by the user, disclose the username and user-id of the user, unveil the email addresses used by the user to download the application and share the videos with other users and expose the social network of the user on the platform. Forensic investigators may find this data helpful in investigating crimes such as cyber bullying, racism, blasphemy, vehicle thefts, road accidents and so on. However, this data-breach in Android devices is a threat to user's privacy, identity and profiling in second-hand market.Practical implicationsPerceived notion of data sanitisation as a result of application removal and factory-reset can have serious implications. Though being helpful to forensic investigators, it leaves the user vulnerable to privacy breach, identity theft, profiling and social network revealing in second-hand market. At the same time, users' sensitivity towards data-breach might compel users to refrain from selling their Android devices in second-hand market and hamper device recycling.Originality/valueThis study attempts to bridge the literature gap in social media data-breach in second-hand Android devices by experimentally determining the extent of the breach. The findings of this study can help digital forensic investigators in solving crimes such as vehicle theft, road accidents, cybercrimes and so on. It can assist smartphone users to decide whether to sell their smartphones in a second-hand market, and at the same time encourage developers and researchers to design methods of social media data sanitisation.

Implementation of a Coronavirus Disease 2019 Vaccination Condition of Employment in a Community Nursing Home

The rate of coronavirus disease 2019 (COVID-19) vaccination uptake by US nursing home staff remains low despite the increased risks of viral transmission and related morbidity and mortality in this setting. This study describes vaccine uptake activities including a COVID-19 vaccination condition of employment (COE) policy in one community nursing home. This case study summarizes the timeline of vaccination uptake activities, staff vaccination rates over time, and stakeholder perspectives around the implementation of a COVID-19 vaccination COE. Organizational data were used to calculate vaccination rates from January 1, 2021 until May 1, 2021 among all nursing home staff. Interviews were held with the executive leadership team, human resources leadership, and nursing home staff to understand the process of implementation. During a 4-month period, nursing home leaders provided 8 written handouts about COVID-19 to all staff, hosted 5 on-site vaccination clinics in partnership with area pharmacies, conducted 2 virtual presentations for staff in addition to individual outreach and internal communications. Fewer than one-half of the staff were vaccinated prior to the decision to pursue a vaccine COE on February 9, 2021. The decision to pursue a COVID-19 vaccination COE was supported by executive leadership and nursing home staff to protect the health and safety of each other and their residents. By May 1, 2021 a total of 221 of the 246 (89.8%) nursing home staff members received a COVID-19 vaccination. The facility reached 100% compliance with the vaccination COE policy with 18 people who chose to resign and 7 people who were exempt or on a leave of absence. In combination with frequent, personalized outreach, a COVID-19 vaccination COE resulted in high staff vaccination rates and minimal staff turnover. This case study provides a detailed summary of vaccination uptake activities within an organizational context to inform efforts at other healthcare facilities.

A probabilistic framework for life-cycle cost analysis of bridge decks constructed with different reinforcement alternatives

Reinforced concrete bridge decks with conventional reinforcement may experience deterioration due to deicing salts or marine environmental conditions. Routine maintenance, rehabilitation, and repair activities are implemented to maintain an acceptable performance level. In addition to the significant financial resources required to conduct these activities, traffic congestions at work zones can lead to an increase in delays and crash risk for road network users, as well as other environmental and social impacts. These user costs arising from traffic congestions can be significantly higher than the cost of maintenance, rehabilitation, and repair activities. Despite the higher initial unit cost, bridge decks constructed with corrosion resistant reinforcement can provide a longer service life and require less maintenance activities. Accordingly, from a life-cycle cost perspective, corrosion resistant reinforcement could be a better alternative compared to conventional reinforcement for bridge decks. This paper presents a probabilistic framework to estimate the life-cycle cost associated with bridge decks constructed with different reinforcement alternatives. The framework accounts for reinforcement deterioration to evaluate the maintenance activity timeline considering influential corrosion-related parameters (e.g., reinforcement type, concrete cover, and bridge location, among others). Key attributes affecting traffic delays, including traffic volume, number of lanes, and vehicular queuing, are also included in the framework. Monte Carlo simulation is used to predict the corrosion-induced cracking time, service life of the bridge deck, and the life-cycle cost under uncertainty. A bridge located in Pennsylvania is used as an illustrative example to demonstrate the application of the proposed framework. The results show that the concrete cover, chloride exposure condition, average daily traffic, and number of traffic lanes have a significant effect on the life-cycle cost of reinforced concrete bridge decks; especially for those constructed with conventional reinforcement. The presented framework can be beneficial in selecting the optimum bridge deck reinforcement type from a life-cycle cost perspective.

Control of antimicrobial resistance in Cameroon: Feasibility of implementing the National Action Plan.

Rising antimicrobial resistance is a major threat worldwide. WHO has developed a Global Action Plan and has urged all countries to develop and implement a National Action Plan. We analysed the implementation of the Cameroon National Action Plan by identifying the prioritised activities and assessing possible challenges which could limit implementation. We conducted a review of national documents on the control of antimicrobial resistance, including regulations, policies and guidelines and assessed the health system structure. Publications and other supporting documents were obtained by a systematic literature search. We applied the policy analysis triangle framework and the theory of change to analyse the National Action Plan, actors involved and the process of implementation. The National Action Plan consisted of six strategic objectives, with the first five being a direct translation of the five pillars of the Global Action Plan. The related activities were to be implemented using a phased approach with allocated targets for each year. Several gaps were identified. There was no timeline of activities set per year, the chronology of activities was not consistent, there were no activities or objectives to ensure the sustainability of the National Action Plan like creating awareness on antimicrobial resistance and the indicators for impact evaluation were not included. Among the actors involved, the Ministry of Public Health had the highest interest in the implementation as the lead stakeholder to oversee the overall implementation. However, there was no clear source of funding, and stakeholders at the primary level of the various sectors responsible for implementation were not clearly defined. Despite adequate multisectoral collaboration within the prioritised activities relevant to Cameroon, more is needed for effective implementation of the National Action Plan. The timeline of the different activities, as well as the involvement of key stakeholders at the primary level, needs to be improved. The government's overall commitment to healthcare should be increased and implementation of an action plan should commence at the district or regional level, while challenges in mobilising the necessary funds need to be overcome.

Historical Continuities and Changes in the Ethnic Politics of Hmong-Miao Millenarianism

ABSTRACT Millenarian movements used to be regarded as native reactions to enormous social disruptions caused by colonial intrusion, doomed to failure and at best a step on the way to more “modern” forms of collective social resistance. In fact, they have both pre-dated and outlasted colonialism, featuring in ethnic politics across Asia and beyond to this day. Nevertheless, its encounter with modernity has not left millenarianism unchanged, as is shown in this article’s historical case study. A comprehensive timeline and mapping of past and present Hmong-Miao millenarian activity highlights several enduring features including a context of economic and political crisis, their transnational nature, the prevalence of manipulation and/or coercion, and specific cultural symbols within supernatural predictions. Equally important are the historical developments, from pan-ethnic to mono-ethnic and from violent to peaceful (but still threatening to political and religious authorities), reflecting historical trends of ethnicisation and territorialisation. The mechanics of such reproductions and transformations are then unpacked, before the Hmong-Miao experience is compared with millenarian activity from other groups of upland Southeast Asia. Millenarianism continues to play a role in voicing social discontent, challenging power structures and moulding ethnic relations, but needs to be examined and understood within evolving socio-political contexts.

HeapCraft: Quantifying and Predicting Collaboration in Minecraft

We present Heapcraft: an open-source suite of tools for monitoring and improving collaboration in Minecraft. At the core of our system is a data collection and analysis framework for recording gameplay. We collected over 3451 player-hours of game behavior from 908 different players, and performed a general study of online collaboration. To make our game analytics easily accessible, we developed interactive information visualization tools and an analysis framework for players, administrators, and researchers to explore graphs, maps and timelines of live server activity. As part of our research, we introduce the collaboration index, a metric which allows server administrators and researchers to quantify, predict, and improve collaboration on Minecraft servers. Our analysis reveals several possible predictors of collaboration which can be used to improve collaboration on Minecraft servers. Heapcraft is designed to be general, and has the potential to be used for other shared online virtual worlds.

Developing Academic Leadership From a Distance: A Health Professions Education Practicum Course.

Leadership skills are fundamental to the successful practice of health professions education (HPE), but HPE degree programs struggle with providing meaningful leadership instruction from a distance. The leaders of the HPE program at the Uniformed Services University of the Health Sciences developed a practicum course to give learners guided experiences in their daily leadership roles and responsibilities from a distance. The ongoing practicum course, started in fall 2018 and broadly framed by the principles of deliberate practice and self-directed learning, involves a 6-step process where learners: (1) identify leadership competency/ies to develop, (2) identify roles and responsibilities in their own work settings that involve elements of leadership, (3) develop a learning agreement that identifies personal leadership goals for the practicum activity, (4) are assigned expert preceptors by practicum directors, (5) initiate regular meetings with their preceptors to receive feedback and expert advice, and (6) end the practicum activity with a debriefing reflection between themselves and their preceptors. Practicum activity timelines are flexible and preceptors work with learners through the lifespan of the project. Learners can participate in multiple practicum activities as they improve different leadership competencies. Since fall 2018, 36 learners have participated in 83 practicum activities, 45 (54%) of which have been completed. The practicum activities show that leadership competencies are most often embedded within other activities and are unique to every situation. Reflecting on practice, collaborating in teams, and negotiating and resolving conflict are the most commonly identified leadership competencies learners want to improve. Feedback on the practicum from learners has been positive. This practicum course provides a model that can be applied in various organizational contexts. In the future, the authors plan to collect data from both learners and preceptors about their experiences and solicit feedback from learners' employers and supervisors.
