Groundwater Protection,Risk Awareness,Knowledge Transfer and Public Health: The Role of “Future Custodians”

A survey of young adults was conducted at several 3rd level agricultural institutions across Ireland over a 6-month period. The results from the agri-student survey were compared and contrasted with those of an identical survey of private well owners. Students (n?=?246) scored significantly lower than well owners (n?=?245) in two developed metrics, namely “groundwater source awareness” and “groundwater contamination awareness” (p?n?=?476). Clusters comprised four predictors: presence of an elderly householder (predictor importance = 0.91), residence within the household during well design (predictor importance = 0.55), presence of an infant or young child (≤5 years) in the household (predictor importance = 0.48) previous instance of gastrointestinal illness or symptoms within the household (predictor importance = 0.31) The results of this research may be used to inform future risk management, communication and knowledge transfer policies, which are currently required to ensure the safeguarding of private groundwater supplies both in Ireland and further afield.     

Alcohol use disorder history moderates the relationship between avoidance coping and posttraumatic stress symptoms.

Avoidance coping (AVC) is common in individuals with posttraumatic stress disorder (PTSD) and in individuals with alcohol use disorder (AUD). Given that PTSD and AUD commonly co-occur, AVC may represent a risk factor for the development of comorbid posttraumatic stress and alcohol use. In this study, the relationship between AVC and PTSD symptoms (PTSS) was examined in individuals with versus without AUDs. Motor vehicle accident (MVA) victims were assessed 6 weeks postaccident for AUD history (i.e. diagnoses of current or past alcohol abuse or dependence) and AVC. PTSS were assessed 6 weeks and 6 months post-MVA. All analyses were conducted on the full sample of MVA victims as well as on the subset of participants who were legally intoxicated (blood alcohol concentration ≥ 0.08) during the accident. It was hypothesized that the relationship between AVC and PTSS would be stronger in those individuals with an AUD history and especially strong in the subset of individuals who were legally intoxicated during the MVA. Results were largely supportive of this hypothesis, even after controlling for in-hospital PTSS, gender, and current major depression. Early assessment of AUD history and avoidance coping may aid in detecting those at elevated risk for PTSD, and intervening to reduce AVC soon after trauma may help buffer the development of PTSD + AUD comorbidity.

Further improvements to the Bauer-Millward attack on the Hill cipher

The Bauer-Millward attack on the Hill cipher seeks to recover the individual rows of the decryption matrix instead of the entire matrix. The authors present some improvements to the Bauer-Millward attack that reduce the computational workload by a factor of φ(L), where φ is the Euler totient function, and L is the length of the alphabet. They also present a method of efficiently combining the top rows to recover the decryption matrix. Performance statistics are provided for blocks up to size 5, and example analyses are given for blocks up to size 8. Previous authors have stopped at size 4.     

A perspective on disgust.

Approaches disgust as a food-related emotion and defines it as revulsion at the prospect of oral incorporation of offensive objects. These objects have contamination properties; if they contact an otherwise acceptable food, they tend to render it inedible. Issues considered include: the nature of the objects of disgust and why they are virtually all of animal origin, the meaning of oral incorporation, the belief that people take on the properties of the foods they eat, the nature of the contamination response and its relation to the laws of sympathetic magic (similarity and contagion), and the ontogeny of disgust, which is believed to develop during the 1st 8 yrs of life. The idea that feces, the universal disgust object, is also the 1st is explored, and the mechanisms for the acquisition of disgust are examined. Disgust is recommended as an easily studiable emotion, a model for cognitive–affective linkages, and a model for the acquisition of values and culture.

An interconnect scheme for reducing the number of contact pads onprocess control chips

An approach is presented to reduce the number of pads required by electrical test structures by using a multiplexed interconnect scheme. This passive multiplexed scheme requires only two levels of interconnect and can be used for transistors, electrical verniers, yield monitoring, reliability evaluations, continuity tests, and measuring the resistance of tracks. The basic measurement procedure to access individual components is to force a voltage on one of the access pads and then ground one of the group terminals via an ammeter. While an even number of pads is not mandatory it is recommended since this maximizes the efficiency of pad usage     

Fabrication and characterization of bandpass filters based onconcatenated chirped fiber gratings

Practical, low-loss (<2 dB), fiber Bragg grating single-passband transmission filters have been realized with >30 dB out-of-band rejection over ~25 mm spectral widths. The approach adopted is based on the concatenation of two or more tailored broadband chirped gratings fabricated with low short-wavelength loss to maximize the rejection and stopband width in a filter with ~1 nm passband. The effect of thermal aging for similar complex structures is considered in the context of three different fiber types: standard telecommunication, high germania (Ge)-doped and boron/germania (B/Ge)-codoped. It is shown that while hydrogenated B/Ge-codoped fiber exhibits excellent photosensitivity, the resulting decrease in guiding strength and thermal stability may make germania-doped fiber the more attractive choice

Large-scale dairy operations: assessing concerns of neighbors about quality-of-life issues

An increasing number of large-scale dairy operations are being built across the United States. Many of the neighbors of proposed large-scale dairy operations are upset at how dairies will affect their quality of life. We assessed the intensity of these concerns at least 1 yr after 2 new dairies began operation. Surveys (n = 275) were mailed to collect data. The opinions (n = 64) of those living close to large-scale dairy operations were compared with those of individuals in control groups (n = 38) living at least 8 km away. There were no significant differences between groups and no complaints had been received, suggesting that quality-of-life issues are specious with regard to properly managed large-scale dairy operations with 700 or fewer cows. We recommend the following for future policy decisions: Large-scale dairy operations should be located in areas where there are few, if any, current neighbors and where future residential development is least likely to occur. Conducting longitudinal studies at intervals of 3 and 5 yr of operation involving these same issues could determine whether any changes in reaction have occurred since this study.
