âEquality and Privacy by Designâ: A New Model of Artificial Intelligence Data Transparency via Auditing, Certification, and Safe Harbor Regimes
A Comprehensive Cybersecurity Policy for the United States Government According to Cyberattacks and Exploits in the 21st Century
Adversaries launch cyberattacks or cyber-exploits with contrasting intentions and desired outcomes. A cyberattack is a malicious attempt by a state, third party, or individual to disrupt a computerâs network; whereas, a cyber-exploit is an action that uncovers and steals âconfidentialâ information from a computerâs data. 1 Within this research paper, the main adversary of such cyberattacks and/or exploits will be the nation-state. The victims of these cyberattacks will range from multinational corporations, such as Sony, to nuclear programs in Iran. This essay will focus on four motivations behind such cyberattacks: (1) private sector hacking (the theft of intellectual property) (2) political gains (3) infrastructure destruction (4) military power. This paper will examine the following cyberattacks: Sony Pictures Hack, Equifax, meddling of the 2016 Presidential Election, OPM Hack, 2015 Ukraine Power Grid Attack, Stuxnet, and Russo-Georgian Cyberattacks. The cyberattacks will serve as a basis to draft a comprehensive United States Foreign Policy that addresses each of the four incentives within a broader cybersecurity strategy. This paper will first explain the diversity of such attacks. Following the analysis, the paper will seek to answer this pressing question: What should the implementation of United States Foreign Policy look like according to contrasting, yet substantial cyberattacks in the past
Can NBA Teams Benefit from Losing?
It has been speculated that franchises in the NBA (national basketball association) lose on purpose because of the benefits that coincide with a team having a poor overall record. Teams that perform the worst are given the highest draft selections in the following season\u27s rookie player draft, thus theoretically improving their chances of becoming a more winning team. Previous economists have used various methodology to prove that NBA teams do in fact lose on purpose; or tank. This paper builds upon this previous methodology to examine the direct impact, negative or positive, that losing on purpose has had on various NBA franchises
Toward regional hazard risk assessment: a method to geospatially inventory critical coastal infrastructure applied to the Caribbean
Hurricanes and sea level rise pose significant threats to infrastructure and critical services (e.g., air and sea travel, water treatment), and can hinder sustainable development of major economic sectors (e.g., tourism, agriculture, and international commerce). Planning for a disaster-resilient future requires high-resolution, standardized data. However, few standardized approaches exist for identifying, inventorying, and quantifying infrastructure lands at risk from natural hazards. This research presents a cost effective, standardized and replicable method to geospatially inventory critical coastal infrastructure land use and components, for use in risk assessments or other regional analyses. While traditional approaches to geospatial inventorying rely on remote sensing or techniques, such as object-based image analysis (OBIA) to estimate land use, the current approach utilizes widely available satellite imagery and a âstandard operating procedureâ that guides individual mappers through the process, ensuring replicability and confidence. As a pilot study to develop an approach that can be replicated for other regions, this manuscript focuses on the Caribbean. Small islands rely heavily on a small number of critical coastal infrastructure (airports, seaports, power plants, water and wastewater treatment facilities) and climate related hazards threaten sustainable development and economic growth. The Caribbean is a large and diverse area, and gaps exist between countries in the resources required for planning but much of the region lacks a comprehensive inventory of the land, infrastructure, and assets at risk. Identifying and prioritizing infrastructure at risk is the first step towards preserving the regionâs economy and planning for a disaster resilient future. This manuscript uses high resolution satellite imagery to identify and geo-spatially classify critical infrastructure land area and assets, such as structures, equipment, and impervious surfaces. We identified 386 critical coastal infrastructure facilities across 28 Caribbean nations/territories, with over 19,000âha of coastal land dedicated to critical infrastructure. The approach establishes a new standard for the creation of geospatial data to assess land use change, risk, and other research questions suitable for the regional scale, but with sufficient resolution such that individual facilities can utilize the data for local-scale analysis
Identifying perinatal risk factors for infant maltreatment: an ecological approach
BACKGROUND: Child maltreatment and its consequences are a persistent problem throughout the world. Public health workers, human services officials, and others are interested in new and efficient ways to determine which geographic areas to target for intervention programs and resources. To improve assessment efforts, selected perinatal factors were examined, both individually and in various combinations, to determine if they are associated with increased risk of infant maltreatment. State of Georgia birth records and abuse and neglect data were analyzed using an area-based, ecological approach with the census tract as a surrogate for the community. Cartographic visualization suggested some correlation exists between risk factors and child maltreatment, so bivariate and multivariate regression were performed. The presence of spatial autocorrelation precluded the use of traditional ordinary least squares regression, therefore a spatial regression model coupled with maximum likelihood estimation was employed. RESULTS: Results indicate that all individual factors or their combinations are significantly associated with increased risk of infant maltreatment. The set of perinatal risk factors that best predicts infant maltreatment rates are: mother smoked during pregnancy, families with three or more siblings, maternal age less than 20 years, births to unmarried mothers, Medicaid beneficiaries, and inadequate prenatal care. CONCLUSION: This model enables public health to take a proactive stance, to reasonably predict areas where poor outcomes are likely to occur, and to therefore more efficiently allocate resources. U.S. states that routinely collect the variables the National Center for Health Statistics (NCHS) defines for birth certificates can easily identify areas that are at high risk for infant maltreatment. The authors recommend that agencies charged with reducing child maltreatment target communities that demonstrate the perinatal risks identified in this study
Road Mortality Threatens Endemic Species in a National Park in Sulawesi, Indonesia
The emerging economy of Indonesia has triggered rapid infrastructure development that threatens ecological communities, including within protected areas. The national parks of Indonesia are renowned for their high levels of biodiversity and endemism, yet the impacts of road development within these parks remains understudied. We conducted road mortality surveys along a 21.8-km section of paved highway that bisects Rawa Aopa Watumohai National Park in Sulawesi, Indonesia from January to April 2018. We documented wildlife carcasses during morning and afternoon surveys and identified hotspots of road mortality for amphibians, reptiles, birds, and mammals. A total of 790 carcasses were observed during 16 surveys, amounting to 2.3 carcasses kmâ1, one of the highest levels reported for Asia. Wildlife recorded during our surveys represented 40 taxa, of which 15% are endemic to the Wallacea region. We documented two hotspots of road mortality for each major taxonomic group. We propose that mitigation measures be implemented at the largest hotspot for amphibians, one overlapping hotspot for amphibians and reptiles, and one overlapping hotspot for birds and mammals, for a total of three areas targeted for mitigation along this 21.8-km section of highway. We recommend the implementation of mitigation measures including highway undercrossings with fencing, reduced speeds with associated signage, and highway lighting at these three hotspot locations to protect the diverse and unique fauna in this national park
Pathological prognostic factors in the second British Stomach Cancer Group trial of adjuvant therapy in resectable gastric cancer.
The second British Stomach Cancer Group trial was a prospective randomised controlled trial of adjuvant radiotherapy or cytotoxic chemotherapy after gastrectomy for adenocarcinoma. It recruited between 1981 and 1986. No survival advantage has been demonstrated for the patients receiving either type of adjuvant therapy compared with those undergoing surgery alone. We report on 436 patients randomised into the trial together with 203 patients, who did not fulfil the trial criteria, referred to the trial. A univariate (log-rank) analysis of pathological factors obtained from the local referring centres showed that tumour size, macroscopic type, number os sites involved, depth of invasion, involvement of resection lines and lymph nodes and histological grade were significant determinants of survival. Histological review by two experienced histopathologists found that the Lauren classification and histological grade, but not the Ming classification, were significant prognostic factors. The degree of lymphocytic and eosinophilic infiltration and presence of dysplasia assessed by one of the pathologists showed a significant correlation with survival. However, inter-observer correlation for these histological parameters and grade was poor. Multivariate analysis identified only depth of invasion, resection line and nodal involvement as significant independent pathological variables influencing survival. This study confirms the need for expert preparation of the resected specimen to obtain the important information on depth of invasion and nodal status and also reveals some variation in histological assessment, particularly grading, in gastric carcinoma
