Honeypots are computer systems deliberately designed to be attack targets, mainly to learn about cyber-attacks and attacker behavior. When implemented as part of a security posture, honeypots also protect real networks by acting as a decoy, deliberately confusing potential attackers as to the real data. The objective of this research is to compare attack patterns against a honeypot to those against a real network, the network of the Naval Postgraduate School. Collection of suspicious-event data required the implementation and setup of a honeypot, in addition to the installation and use of an intrusion-detection system. A statistical analysis was conducted across suspicious-event data recorded from a honeypot and from a real network. Metrics used in our study were applied to the alerts generated from Snort 2.4.3, an open-source intrusion detection system. Results showed differences between the honeypot and the real network data which need further experiments to understand. Both the honeypot and the real network data showed much variability at the start of the experiment period and then a decrease in the number of alerts in the later period of the experiment. We conclude that after the initial probing and reconnaissance is complete, the vulnerabilities of the network are learned and therefore fewer alerts occur; but more specific signatures are then aimed at exploiting the network.

<p> The Lake Titlow watershed (approximately 35,000 acres) in south-central Minnesota is part of the Minnesota River Basin. The lake is listed in the draft 2010 Clean Water Act Section 303d for nutrient pollution, eutrophication, and biological indicators for impairment of aquatic life and recreational use. Over 90 percent of pre-settlement wetlands are currently drained for agricultural land use. The Lake Titlow watershed is over 80 percent row crops and land use is implicated as a primary cause of impairment in the lake. </p><p> Water samples were collected from the Lake Titlow tributaries McLeod-Sibley Judicial Ditch Number 18 (JD18), Sibley County Ditch Number 18 (CD18), and Ditch 250 (D250) during 2009 and 2010 and were analyzed for total suspended solids (TSS), total phosphorus (TP), and nitrate-nitrite nitrogen (NOx). Investigative methods included continuous recording stream stage and through the use of rating curves, discharge. Runoff, sediment loads, and nutrient loads were then determined from the field data. Four rain gauges collected precipitation each year and were used to assess the impact of precipitation on runoff and loading. Four characteristic precipitation events were selected for each of the calendar years 2009 and 2010 to estimate the loads of sediment and nutrients to the lake and more fully understand the specific roles that land use, hydrologic soil group, slope, and precipitation play with regard to causing sediment and nutrient loading in the lake. </p><p> Results indicate runoff and loads are significant and highly variable by position within the watershed, areas referred to herein as subsheds. The row crop land use, soils characteristics, and precipitation do contribute to overall runoff and loads; however, they do not control subshed variability. Although the low-sloping land surfaces of the watershed should not contribute to overall runoff and loads, results indicate that subtle slope changes in the JD18Lo and CD18Lo subsheds could contribute to the variability of loads seen in these portions of the watershed. </p><p> The location and type of best management practices to implement is debatable because the results of this study indicate that large runoffs and loads could originate within any given subshed during any given rainstorm event. This study was unable to precisely identify the root cause of the variability in subshed runoff and loading. Therefore, it is suggested to look at other factors (e.g., antecedent soil moisture, rainfall intensity, mass wasting, etc.) to explain the subshed variability in the sediment and nutrient loading in future studies of this lakeshed.</p>

<p> In today&rsquo;s world, people from various cultures interact on a daily basis on a number of occasions. During these intercultural encounters, conflicts often arise. Intercessors are needed to help people navigate these types of disagreements. Mediators are considered some of these peacekeepers. This thesis engaged with mediators at a mediation center in the Midwestern United States in order to understand what strategies seemed most effective. </p><p> I examined the research that scholars have conducted regarding building rapport through utilizing respect and face issues, as well as nonverbal behavior. In addition, I explored the connection between the understanding of these factors and intercultural competence and intercultural conflict competence. </p><p> The purpose of this thesis was to see how these mediators understood and valued respect and face issues, including nonverbal behavior, when building rapport with parties in mediations. These mediators were engaged in two manners, via survey and interview questions. The intercultural competence of the mediators in these domains was also explored. </p><p> The results of the research in this thesis showed how the mediators were skilled in some areas, such as in rapport building and respect issues. It further revealed that they were in need of some skills for their toolbox, such as training on face issues and nonverbal behavior, including silence, tone of voice, and eye contact. Detailed recommendations for the mediators are provided. Future research is encouraged: A group of mediators that have exhibited intercultural competence should be selected in order to test their intercultural conflict competence.</p>

<p> This study compared two remote sensing water indices: the Normalized Difference Water Index (NDWI) and the Modified NDWI (MNDWI). Both indices were calculated using publically-available data from the Landsat 8 Operational Land Imager (OLI). The research goal was to determine whether the indices are effective in locating open water and measuring surface soil moisture. To demonstrate the application of water indices, analysis was conducted for freshwater wetlands in the Tualatin River Basin in northwestern Oregon to estimate hydrologic connectivity and hydrological permanence between these wetlands and nearby water bodies. Remote sensing techniques have been used to study wetlands in recent decades; however, scientific studies have rarely addressed hydrologic connectivity and hydrologic permanence, in spite of the documented importance of these properties. Research steps were designed to be straightforward for easy repeatability: 1) locate sample sites, 2) predict wetness with water indices, 3) estimate wetness with soil samples from the field, 4) validate the index predictions against the soil samples from the field, and 5) in the demonstration step, estimate hydrologic connectivity and hydrological permanence. Results indicate that both indices predicted the presence of large, open water features with clarity; that dry conditions were predicted by MNDWI with more subtle differentiation; and that NDWI results seem more sensitive to sites with vegetation. Use of this low-cost method to discover patterns of surface moisture in the landscape could directly improve the ability to manage wetland environments.</p>

<p> Evaluating trends of historical rainfall on a weekly and seasonal basis is needed for optimizing the design and implementation of lawn water conservation strategies like outdoor water restrictions. While &ldquo;day of the week&rdquo; water restrictions are a typical strategy to limit the frequency and duration of urban lawn water use, they may not necessarily result in more conservative behaviors from end-users. Because weekly rainfall and local climate variables are seldom taken into account in water restriction strategies, they are not connected to actual lawn water demand. However, since lawn water demand is directly related to weekly rainfall totals, not to a particular number of watering days per week, water restriction schedules have the potential to unintentionally promote overwatering. This study investigated the weekly patterns of average seasonal rainfall and evapotranspiration in South Florida to determine the typical variability of weekly net irrigation needs and found that typical wet season weekly rainfall often provides a significant amount of water to meet the demand of residential lawns and landscapes. This finding underscores opportunity to reduce supplemental overwatering in residential landscapes if watering guidelines were modified to recognize seasonal average weekly rainfall in this region. </p><p> This study also tested a rainfall-based water conservation strategy to determine if providing residents with information about how local rainfall could promote more effective lawn watering behavior than just water restrictions alone. Experimental households reduced lawn water use by up to 61% compared to the control group by the end of the study. These results demonstrate that the neighborhood &ldquo;rain-watered lawn&rdquo; signs helped experimental study group households become more aware of rainfall as the primary input of water to their lawns. This study also investigated the role that lawn irrigation from self-supplied sources plays in the urban lawn water demand and investigates how the lawn water use and lawn watering behaviors of households that source from self-supply differ from those who source from the public supply.</p>

This study investigates the influence that increasing end user autonomy has on organizational data models. The independence offered by microcomputer technology offers users increasing independence in their information-handling activities. As independence increases, uniformity of data models across the organization is theorized to diminish. The problem motivating this study is the potential for improper allocation of resources that may result from a misinterpretation of organizational data. This study suggests that the expanding use of microcomputers in the business setting will contribute to diversity of data models. This may eventually lead to confusion and even lack of confidence in the information produced.

Increasing development like roads and houses will alter the future landscape of Vermont. Development provides important resources for people and society, but also results in consequences for wildlife and opportunities for recreation. Managing development requires information on the public's acceptability of development and how acceptability is shaped by information on various consequences. In this study, I examined three questions: 1) What is the public's acceptability of development? 2) Does wildlife information influence public acceptability of development and 3) Is the maximum amount of acceptable development influenced by views about wildlife, involvement in recreation, and demographic factors? I surveyed 9,000 households in Vermont by including a questionnaire which asked about development, wildlife, recreation, and demographics. I assessed acceptability of amount of development using social-norm curves and used parametric significance tests and mixed-effects models to examine the influence of wildlife, recreation, and demographic factors. The survey response rate was 44%. The maximum acceptable amount of development was slightly more than 32 households/km2, and not meaningfully influenced by the broader consequences of development on seven common wildlife species. The public demonstrated a strong preference for clustered development over sprawled development, which became unacceptable at 20 households per km2. Maximum acceptability of development was significantly influenced by views on some species, including bear, bobcat, and fisher, but not by others such as deer, fox, raccoon, and coyote. Similarly, those involved in common forms of outdoor recreation, including birding, ATVing, hunting, fishing and camping, were significantly less accepting of development relative to those not involved in these forms of recreation. Maximum amount of development was also affected by demographic factors, including town density, respondent age, home ownership and location of birth. The results provide a baseline measure of the public's acceptability of development, which can be used to guide decision-making about amount and pattern of development, wildlife management, and efforts to promote recreation in the state.

The following research project examines the effects of polychlorinated biphenyls (PCBs) on the environment and the cultural integrity of the St. Regis Mohawk tribe in the Mohawk Nation of Akwesasne. This indigenous community has been subjected to widespread long-term industrial pollution from nearby toxic hazardous waste facilities and Superfund sites. The Mohawk Nation of Akwesasne has the distinction of being the only tribe whose officially recognized territory straddles the border between the United States and Canada. Using qualitative methodologies, coupled with an interdisciplinary framework, this study successfully engages with Akwesasne community members to explore such issues as bottom-up approaches to addressing complex environmental issues, by gaining a comprehensive understanding of organizational structures and tribal governance networks. This study also identifies a clear parallel between the Mohawk Nation of Akwesasne's struggles and history of environmental justice efforts in the U .S. by articulating the effects of environmental degradation on their cultural integrity, in addition to surfacing themes of resistance and resilience in the community as building blocks for future action. The research project focuses on the place of the community's voice in the transnational public policy response to PCB contamination in the Mohawk Nation of Akwesasne. Three case studies were conducted in environmental organizations on the Mohawk Nation territory: the St. Regis Mohawk Tribe Environment Division, the Mohawk Council of Akwesasne, and the Akwesasne Task Force on the Environment. These environmental organizations have been working to protect the environment for approximately three decades. A case study analysis relies on data collected from interviews with staff members to determine how they organized themselves to address the environmental and social disruption caused by exposure to harmful chemical pollutants. Strong parallels can be drawn as a result of an analysis of environmental justice literature, since native communities have not, traditionally, been included in the scholarly academic literature on the Environmental Justice Movement in the United States. In addition to information gathered from institutional policy actors and related stakeholders, in-depth interviews with community members revealed a community framework for future policy development and action. Finally, the research focuses on how those community voices articulate the impacts of PCB contamination on the natural resources in the area, and as a result, on the ability of the St. Regis Mohawk tribe to maintain their culture, heritage, ceremonies, and traditional way of life.

The widespread distribution of personal computers (PCs) throughout organizations has made a substantial impact on information systems. Additionally, the tremendous growth of the Internet has changed the way business is carried out. As the user population evolves into a much more technical and demanding group, their needs are also changing. With this change, Management Information Systems (MIS) departments must develop new ways of providing service and support to the user community. This study investigates the relationship between information systems support structures, support services, service quality and the characteristics of a diverse user population. This includes investigating technical support issues influencing user satisfaction. This study attempts to improve the understanding of the support function within MIS. The results of this study clarify the support needs of the users and identify user satisfaction factors, as well as factors relative to the quality of the support received. Six streams of prior research were reviewed when developing the research framework. These include: user support, end users and end-user computing, identifying and classifying user types, information centers, user satisfaction, service quality and other sources of computer support. A survey instrument was designed using the (UIS) user satisfaction instrument developed by Doll and Torkzadeh (1988) and the SERVQUAL instrument as modified by Kettinger and Lee (1994). The survey was distributed to 720 individuals. A total of 155 usable responses were analyzed providing mixed results. Of the ten hypotheses, only four were rejected. The finding of this study differ from those in earlier studies. The variables that were found to be significant to the users for service quality are the method of support that is provided to the user, i.e., help desk or local MIS support and the support technician's experience level. For user satisfaction the location of the service personnel made a difference to the end user. As with service quality, the support technician's experience level added to the users' satisfaction with MIS support. The results of this study are pertinent to managers of MIS departments as it clarifies the support needs of the users and identifies issues of user satisfaction and service quality.

A research report submitted to the Faculty of Humanities, School of Human and Community Development, in partial fulfilment of the requirements for the degree of Master of Arts by coursework and research report in the field of in Organisational Psychology, University of the Witwatersrand, Johannesburg September 2017 / Emails have become a fundamental computer application and business tool, in organisations across the global. This is because of the accessibility and convenience of emails which have generated an array of benefits to both employees and their organisations. However, this accessibility has led to an over-reliance on emails, which often has the negative consequence of email overload. Email overload continues to be a recurring issues experienced by employees universally, which research has found to have negative implications on employees’ wellbeing and productivity. Yet there has been limited research, particularly in South Africa, that aims to reduce email overload among employees. Thus, this research report investigated how the role of providing employees with a job resource (training intervention) could increase perceived productivity and eliminate email overload and change caused by the job demands (emails) on employees .In order to examine this effect, this research utilised a pretest post-test control group design on order to compare the impact of a training intervention in reducing email overload and increasing productivity. The quantitative results revealed that the training intervention contributed to a decrease in feelings of email overload among the participants. Additionally, focus groups were administered to determine participants’ experience with emails both prior to the training and after the training, to gain a clearer understanding of the best practices used to eliminate email overload. These findings observed that the participants transferred learnt contents from training into their working lives. Thus research both further contributes to other research currently associated with email and email overload, and also provides a greater understanding of the need to provide employees with job resources much like training intervention in order to counteract those job demands like emails, that are often ignored. / XL2018
