Enhancing Social Support Through Adventure Education: The Case Of Fathers And Sons, Curt Davidson, Alan Ewert Jan 2012

Enhancing Social Support Through Adventure Education: The Case Of Fathers And Sons, Curt Davidson, Alan Ewert

Research in Outdoor Education

Adventure education (AE) research often utilizes social support as an outcome variable associated with participation in extended outdoor adventure trips. Social support is defined as “the degree to which individuals have access to social resources, in the form of relationships, on which they can rely” (Johnson & Sarason, 1979). Using an adventure-based program offering a treatment specifically designed for father and son participants, significant changes in pre-post comparison scores on the variables of trust, communication, and social support were reported for both fathers and sons. Qualitative analysis revealed four major themes: communication enhancement, instructor influence, course components, and shared time. …

Dns In Computer Forensics, Neil F. Wright

Journal of Digital Forensics, Security and Law

The Domain Name Service (DNS) is a critical core component of the global Internet and integral to the majority of corporate intranets. It provides resolution services between the human-readable name-based system addresses and the machine operable Internet Protocol (IP) based addresses required for creating network level connections. Whilst structured as a globally dispersed resilient tree data structure, from the Global and Country Code Top Level Domains (gTLD/ccTLD) down to the individual site and system leaf nodes, it is highly resilient although vulnerable to various attacks, exploits and systematic failures.

Digital Evidence Education In Schools Of Law, Aaron Alva, Barbara Endicott-Popovsky Jan 2012

Digital Evidence Education In Schools Of Law, Aaron Alva, Barbara Endicott-Popovsky

Journal of Digital Forensics, Security and Law

An examination of State of Connecticut v. Julie Amero provides insight into how a general lack of understanding of digital evidence can cause an innocent defendant to be wrongfully convicted. By contrast, the 101-page opinion in Lorraine v. Markel American Insurance Co. provides legal precedence and a detailed consideration for the admission of digital evidence. An analysis of both cases leads the authors to recommend additions to Law School curricula designed to raise the awareness of the legal community to ensure such travesties of justice, as in the Amero case, don’t occur in the future. Work underway at the University …

Identifying Trace Evidence From Target-Specific Data Wiping Application Software, Gregory H. Carlton, Gary C. Kessler Jan 2012

Identifying Trace Evidence From Target-Specific Data Wiping Application Software, Gregory H. Carlton, Gary C. Kessler

Journal of Digital Forensics, Security and Law

One area of particular concern for computer forensics examiners involves situations in which someone utilized software applications to destroy evidence. There are products available in the marketplace that are relatively inexpensive and advertised as being able to destroy targeted portions of data stored within a computer system. This study was undertaken to analyze a subset of these tools in order to identify trace evidence, if any, left behind on disk media after executing these applications. We evaluated five Windows 7 compatible software products whose advertised features include the ability for users to wipe targeted files, folders, or evidence of selected …

Forensic Evidence Identification And Modeling For Attacks Against A Simulated Online Business Information System, Manghui Tu, Dianxiang Xu, Eugene Butler, Amanda Schwartz Jan 2012

Forensic Evidence Identification And Modeling For Attacks Against A Simulated Online Business Information System, Manghui Tu, Dianxiang Xu, Eugene Butler, Amanda Schwartz

Journal of Digital Forensics, Security and Law

Forensic readiness of business information systems can support future forensics investigation or auditing on external/internal attacks, internal sabotage and espionage, and business fraud. To establish forensics readiness, it is essential for an organization to identify which fingerprints are relevant and where they can be located, to determine whether they are logged in a forensically sound way and whether all the needed fingerprints are available to reconstruct the events successfully. Also, a fingerprint identification and locating mechanism should be provided to guide potential forensics investigation in the future. Furthermore, mechanisms should be established to automate the security incident tracking and reconstruction …

Wicked Tools: The Value Of Scientific Models For Solving Maine’S Wicked Problems, Tim Waring Jan 2012

Wicked Tools: The Value Of Scientific Models For Solving Maine’S Wicked Problems, Tim Waring

Maine Policy Review

“Wicked problems” are urgent, high-stake socioeconomic-environmental challenges that often involve ideological conflict and have no “best solutions.” Using examples from Maine’s Sustainability Solutions Initiative projects, Tim Waring describes how scientific models can be used to address these kinds of problems. When well-constructed and tested models are used to address policy-relevant issues, include input from stakeholders, and integrate social, economic and environmental dynamics, they can become “wicked tools” to address some of society’s biggest challenges.

Development Of A Soil Carbon Index For Iowa Mineral Soils, M. M. Al-Kaisi, T. E. Fenton, J. G. Guzman, B. R. O'Neal Jan 2012

Development Of A Soil Carbon Index For Iowa Mineral Soils, M. M. Al-Kaisi, T. E. Fenton, J. G. Guzman, B. R. O'Neal

Journal of the Iowa Academy of Science: JIAS

A carbon index (Cl) is one of many soil quality indicators that depends on organic carbon concentration. One of the values of a soil carbon index is in determining the impact of agriculture practices (i.e., tillage, crop rotation, N management, etc.) on soil organic matter status of mineral soils. Interactions of climate, parent material, topography, time, and organisms including human activities influence soil organic carbon (SOC). This study developed a soil carbon index for mineral soil map units in Iowa using data collected by the Iowa Cooperative Soil Survey Laboratory and the USDA Soil Survey Laboratory for over 2,300 soil …

Effects Of Berberine, Chelerythrine, And Sanguinarine On Proliferation In Four Human Immortalized Cell Lines, David S. Senchina, Nisarg B. Shah, Marc G. Busch Jan 2012

Effects Of Berberine, Chelerythrine, And Sanguinarine On Proliferation In Four Human Immortalized Cell Lines, David S. Senchina, Nisarg B. Shah, Marc G. Busch

Journal of the Iowa Academy of Science: JIAS

Bloodroot (Sanguinaria canadensis L., Papaveraceae) is a plant rich in benzophenanchridine (isoquinoline) alkaloids such as sanguinarine and chelerychrine. Both isolated alkaloids and whole-tissue rhizome extracts have demonstrated in vitro anticarcinogenic (antiproliferacive) activity in limited immortalized cell culture models, but the relative contribution of various alkaloid constituents to whole-tissue extract activity, and whether or not various alkaloids may act synergistically, has not been investigated. We challenged four immortalized cell lines (Jurkat, K562, Ramos, U937) with various doses of chelerythrine, sanguinarine, and berberine (a structurally and functionally similar alkaloid absent from bloodroot), alone and in all possible combinations, and measured proliferation …

Evidence From Detrital Zircon Ages For Middle Pennsylvanian Uplift And Drainage In The Source Area Of The Chariton Conglomerate And Marmaton Group Sandstones, Southern Iowa And Northern Missouri, Scott Mcfadden, Steven H. Emerman, Jane Pedrick Dawson, Kevin A. Rey, Tracy Kemp Anderson

Journal of the Iowa Academy of Science: JIAS

The Chariton Conglomerate is a quartz/limestone conglomerate of Middle Pennsylvanian age sparsely exposed in southern Iowa and northern Missouri. In Iowa it is characterized by quartz granules and rounded crinoid columnals. The objective of this study was to use detrital zircon ages to determine the provenance of the Chariton Conglomerate and possibly associated Marmaton Group sandstone beds. Detrital zircon ages were obtained for five conglomerate and two sandstone beds of the Chariton Conglomerate in Iowa, three conglomerate beds of the Chariton Conglomerate in Missouri, and two sandstone beds of the Marmaton Group in Iowa. According to the Kolmogorov-Smirnoff Test, the …

Harlan's Ground Sloth (Paramylodon Harlant) (Xenarthra: Mylodontidae) From The Late Pleistocene (Rancholabrean) Of Iowa, H. Gregory Mcdonald Jan 2012

Harlan's Ground Sloth (Paramylodon Harlant) (Xenarthra: Mylodontidae) From The Late Pleistocene (Rancholabrean) Of Iowa, H. Gregory Mcdonald

Journal of the Iowa Academy of Science: JIAS

Harlan's ground sloth, Paramylodon harlani, is documented for the first time from Iowa. The record is based on a fifth metacarpal recovered from a gravel bar within West Tarkio Creek, Page County. While the specimen was not found in situ, and could not be radiocarbon dated, the local geology suggests that it was probably derived from sediments that post-date Peorian loess deposition and is late Wisconsinan in age. This specimen extends the range of Paramylodon 350 km ro the northeast of the closest previously known locality. Its size is slightly larger than average for other late Pleisrocene (Rancholabrean) …

A Reply To David Richards’ Review Of Measuring Human Rights, Todd Landman, Edzia Carvalho Jan 2012

A Reply To David Richards’ Review Of Measuring Human Rights, Todd Landman, Edzia Carvalho

Human Rights & Human Welfare

Professor Richards highlights, in his generous review of our book Measuring Human Rights that one of the aims of the book is to bring to the forefront the importance of conceptualization before operationalization – that conceptual clarity (or lack of it) is at the heart of the problems concerning the measurement of human rights. He draws out three key issues from the book as the springboard for further discussion on measurement of the concept – a) the “Respect, Protect and Fulfill” (RPF) framework, b) the lack of reliable data sources, and c) the conceptual links between human rights, human development, …
