Restricting wireless network access within the classroom

Wireless Local Area Networks (WLANs) are fast becoming the networks of choice. With the availability of cheap wireless solutions, WLANs are seeing exponential growth which is expected to continue in the years to come. Over 50% of college classrooms have wireless network availability. Instructors have discovered that along with the benefits of WLANs there are also many students misusing the wireless network during class. This paper provides a solution to the multiple access point problem and proposes a system that can be used to control wireless network access in the classroom. The wireless network control system is based off of CNAC(7) and uses passive wireless sniffers to determine wireless clients location. The wireless sniffer is placed in the classroom and passively monitors all wireless traffic and records Received Signal Strength (RSS). The sniffing of RSS allows the system to know what wireless clients are broadcasting from inside of the room. This information is then passed onto the monitoring system that is placed on the network in a location that is able to see all network traffic. The system then monitors and filters traffic based on the instructors requirements

The Catholic Seven: A Marketing Analysis & Proposal

This project was submitted in partial fulfillment of the requirements for the Master of Science in Journalism degree.In December 2012, seven Catholic schools from the Big East Conference announced plans to vacate the Big East and create their own league, quickly dubbed the "Catholic Seven." Besides their religious affiliation, these seven schools share basketball as their primary revenue-driving sport and do not compete in Division I football. Three University of Kansas graduate students worked to research and develop a marketing and branding strategy for the newly-formed league

Anlass oder Legitimation? Zum Verhältnis zwischen rechter Gewalt und Ideologie

Starting out from the thesis that in many cases the research on violence misunderstands the significance of ideology for violence within a society, the text pursues the question of how violence and ideology are related to each other. Based on culture-philosophical studies on the nature and effect of myths, the author grasps ideology as a secondary myth, to describe the deeply affective rooting of the ideological narrative in the personality-structures of individual right-wing violent criminals and right–wing groups of criminals. Then these considerations are confronted with the biographies and deeds of three right-wing extremist violent criminals, to finally discuss them accordingly

No Pain No Gain: Standards mapping in Latimer Core development

Latimer Core (LtC) is a new proposed Biodiversity Information Standards (TDWG) data standard that supports the representation and discovery of natural science collections by structuring data about the groups of objects that those collections and their subcomponents encompass (Woodburn et al. 2022). It is designed to be applicable to a range of use cases that include high level collection registries, rich textual narratives and semantic networks of collections, as well as more granular, quantitative breakdowns of collections to aid collection discovery and digitisation planning.As a standard that is (in this first version) focused on natural science collections, LtC has significant intersections with existing data standards and models (Fig. 1) that represent individual natural science objects and occurrences and their associated data (e.g., Darwin Core (DwC), Access to Biological Collection Data (ABCD), Conceptual Reference Model of the International Committee on Documentation (CIDOC-CRM)). LtC's scope also overlaps with standards for more generic concepts like metadata, organisations, people and activities (i.e., Dublin Core, World Wide Web Consortium (W3C) ORG Ontology and PROV Ontology, Schema.org). LtC represents just an element of this extended network of data standards for the natural sciences and related concepts. Mapping between LtC and intersecting standards is therefore crucial for avoiding duplication of effort in the standard development process, and ensuring that data stored using the different standards are as interoperable as possible in alignment with FAIR (Findable, Accessible, Interoperable, Reusable) principles. In particular, it is vital to make robust associations between records representing groups of objects in LtC and records (where available) that represent the objects within those groups.During LtC development, efforts were made to identify and align with relevant standards and vocabularies, and adopt existing terms from them where possible. During expert review, a more structured approach was proposed and implemented using the Simple Knowledge Organization System (SKOS) mappingRelation vocabulary. This exercise helped to better describe the nature of the mappings between new LtC terms and related terms in other standards, and to validate decisions around the borrowing of existing terms for LtC. A further exercise also used elements of the Simple Standard for Sharing Ontological Mappings (SSSOM) to start to develop a more comprehensive set of metadata around these mappings. At present, these mappings (Suppl. material 1 and Suppl. material 2) are provisional and not considered to be comprehensive, but should be further refined and expanded over time.Even with the support provided by the SKOS and SSSOM standards, the LtC experience has proven the mapping process to be far from straightforward. Different standards vary in how they are structured, for example, DwC is a 'bag of terms', with informal classes and no structural constraints, while more structured standards and ontologies like ABCD and PROV employ different approaches to how structure is defined and documented. The various standards use different metadata schemas and serialisations (e.g., Resource Description Framework (RDF), XML) for their documentation, and different approaches to providing persistent, resolvable identifiers for their terms. There are also many subtle nuances involved in assessing the alignment between the concepts that the source and target terms represent, particularly when assessing whether a match is exact enough to allow the existing term to be adopted. These factors make the mapping process quite manual and labour-intensive. Approaches and tools, such as developing decision trees (Fig. 2) to represent the logic involved and further exploration of the SSSOM standard, could help to streamline this process.In this presentation, we will discuss the LtC experience of the standard mapping process, the challenges faced and methods used, and the potential to contribute this experience to a collaborative standards mapping within the anticipated TDWG Standards Mapping Interest Group

Toxicology Studies on Lewisite and Sulfur Mustard Agents: Subchronic Toxicity of Sulfur Mustard (HD) In Rats Final Report

Occupational health standards have not been established for sulfur mustard [bis(2- chlorethyl)-sulfide], a strong alkylating agent with known mutagenic properties. Seventytwo Sprague-Dawley rats of each sex, 6-7 weeks old, were divided into six groups (12/group/ sex) and gavaged with either 0, 0.003 , 0.01 , 0.03 , 0.1 or 0.3 mg/kg of sulfur mustard in sesame oil 5 days/week for 13 weeks. No dose-related mortality was observed. A significant decrease (P ( 0.05) in body weight was observed in both sexes of rats only in the 0.3 mg/kg group. Hematological evaluations and clinical chemistry measurements found no consistent treatment-related effects at the doses studied. The only treatment-related lesion associated with gavage exposure upon histopathologic evaluation was epithelial hyperplasia of the forestomach of both sexes at 0.3 mg/kg and males at 0.1 mg/kg. The hyperplastic change was minimal and characterized by cellular disorganization of the basilar layer, an apparent increase in mitotic activity of the basilar epithelial cells, and thickening of the epithelial layer due to the apparent increase in cellularity. The estimated NOEL for HD in this 90-day study is 0.1 mg/kg/day when administered orally

Teratology Studies on Lewisite and Sulfur Mustard Agents: Effects of Sulfur Mustard in Rats and Rabbits

Sulfur mustard (HD) was administered to rats and rabbits by intragastric intubation. Rats were dosed daily from 6 through 15 days of gestation (dg) with 0. 0.5, 1.0 or 2.0 mg of HD/kg; rabbits were dosed with 0, 0.4, 0.6 or 0.8 mg/kg on 6 through 19 dg. Maternal animals were weighed periodically and, at necropsy, were examined for gross lesions of major organs and reproductive performance; live fetuses were weighed and examined for external, internal and skeletal defects. In rats, reductions in body weights were observed in maternal animals and their female fetuses at the lowest administered dose (0.5 mg/kg), but the incidence of fetal malformations was not increased. In rabbits the highest administered dose (0.8 mg/kg) induced maternal mortality and depressed body weight measures but did not affect fetal development. These results suggest that orally administered HD is not teratogenic in rats and rabbits since fetal effects were observed only at dose levels that induced frank maternal toxicity. Estimations of dose ranges for "no observable effects levels" in rats and rabbits, respectively, were: 0.8 mg/kg in their fetuses

Toxicology Studies on Lewisite and Sulfur Mustard Agents: Two-Generation Reproduction Study of Lewisite in Rats Final Report

Occupational health standards have not been established for Lewisite [bis(2-chlorethyl)arsine], a potent toxic vesicant which reacts with the sulfhydryl groups of proteins through its arsenic group. The purposes of this study were to determine the reproductive consequences and dose~response of continuing Lewisite exposure of parental males and females and their offspring in a 42-week two-generation study. Solutions of Lewisite were prepared for administration by diluting the neat agent with sesame oil. Rats were administered Lewisite (0, 0.10, 0.25 or 0.60 mg/kg/day for 5 days a week) via intragastric intubation prior to mating, during mating and after mating until the birth of their offspring. The dams continued to receive Lewisite during lactation. At weaning, male and female offspring of each group were selected to continue on the study; rece1v1ng Lewisite during adolescence, mating and throughout gestation. Again, the dams continued to receive Lewisite until weaning of the offspring. Lewisite had no adverse effect on reproduction performance, fertility or reproductive organ weights of male or female rats through two consecutive generations. No adverse effect to offspring were attributed to Lewisite exposure. Minor changes in growth was the only maternal effect observed. Lewisite exposure of parental rats caused no gross or microscopic lesions in testes, epididymis, prostrate, seminal vesicles, ovaries, uterus or vagina. Severe inflammation of the lung was observed at necropsy in cases in which Lewisite gained access to the respiratory system from accidental dosing or reflux and aspiration; this usually caused early death of the animal. The NOEL for reproductive effects in this study was greater than 0.60 mg/kg/day

Participative decision making and the sharing of benefits: laws, ethics, and data protection for building extended global communities

Transdisciplinary and cross-cultural cooperation and collaboration are needed to build extended, densely interconnected information resources. These are the prerequisites for the successful implementation and execution of, for example, an ambitious monitoring framework accompanying the post-2020 Global Biodiversity Framework (GBF) of the Convention on Biological Diversity (CBD; SCBD 2021). Data infrastructures that meet the requirements and preferences of concerned communities can focus and attract community involvement, thereby promoting participatory decision making and the sharing of benefits. Community acceptance, in turn, drives the development of the data resources and data use. Earlier this year, the alliance for biodiversity knowledge (2021a) conducted forum-based consultations seeking community input on designing the next generation of digital specimen representations and consequently enhanced infrastructures. The multitudes of connections that arise from extending the digital specimen representations through linkages in all “directions” will form a powerful network of information for research and application. Yet, with the power of an extended, accessible data network comes the responsibility to protect sensitive information (e.g., the locations of threatened populations, culturally context-sensitive traditional knowledge, or businesses’ fundamental data and infrastructure assets). In addition, existing legislation regulates access and the fair and equitable sharing of benefits. Current negotiations on ‘Digital Sequence Information’ under the CBD suggest such obligations might increase and become more complex in the context of extensible information networks. For example, in the case of data and resources funded by taxpayers in the EU, such access should follow the general principle of being “as open as possible; as closed as is legally necessary” (cp. EC 2016). At the same time, the international regulations of the CBD Nagoya Protocol (SCBD 2011) need to be taken into account. Summarizing main outcomes from the consultation discussions in the forum thread “Meeting legal/regulatory, ethical and sensitive data obligations” (alliance for biodiversity knowledge 2021b), we propose a framework of ten guidelines and functionalities to achieve community building and drive application: Substantially contribute to the conservation and protection of biodiversity (cp. EC 2020). Use language that is CBD conformant. Show the importance of the digital and extensible specimen infrastructure for the continuing design and implementation of the post-2020 GBF, as well as the mobilisation and aggregation of data for its monitoring elements and indicators. Strive to openly publish as much data and metadata as possible online. Establish a powerful and well-thought-out layer of user and data access management, ensuring security of ‘sensitive data’. Encrypt data and metadata where necessary at the level of an individual specimen or digital object; provide access via digital cryptographic keys. Link obligations, rights and cultural information regarding use to the digital key (e.g. CARE principles (Carroll et al. 2020), Local Context-labels (Local Contexts 2021), licenses, permits, use and loan agreements, etc.). Implement a transactional system that records every transaction. Amplify workforce capacity across the digital realm, its work areas and workflows. Do no harm (EC 2020): Reduce the social and ecological footprint of the implementation, aiming for a long-term sustainable infrastructure across its life-cycle, including development, implementation and management stages. Balancing the needs for open access, as well as protection, accountability and sustainability, the framework is designed to function as a robust interface between the (research) infrastructure implementing the extensible network of digital specimen representations, and the myriad of applications and operations in the real world. With the legal, ethical and data protection layers of the framework in place, the infrastructure will provide legal clarity and security for data providers and users, specifically in the context of access and benefit sharing under the CBD and its Nagoya Protocol. Forming layers of protection, the characteristics and functionalities of the framework are envisioned to be flexible and finely-grained, adjustable to fulfill the needs and preferences of a wide range of stakeholders and communities, while remaining focused on the protection and rights of the natural world. Respecting different value systems and national policies, the framework is expected to allow a divergence of views to coexist and balance differing interests. Thus, the infrastructure of the digital extensible specimen network is fair and equitable to many providers and users. This foundation has the capacity and potential to bring together the diverse global communities using, managing and protecting biodiversity
