Show moreThe Dyadic Adjustment Scale (DAS) is the most widely used measure of dyadic adjustment for individuals in committed relationships (Spanier, 1976). However, little research has focused on whether DAS measures the construct of dyadic adjustment in a way that is equivalent and unbiased across genders. The current study utilized matched moderated regression (MMR) to assess each item of the DAS to detect if gender differences in the relationships between item responses and the construct being measured are due to (a) factors other than the construct and (b) differences in the construct. Archival data were acquired from a previously published study (Eddy, Heyman, & Weiss, 1991). The sample was very large (N =3322) so it was divided into two replication groups in such a way that no couples were included in the same group. A number of statistically significant differences were found on items in both replication samples; however: (1) many of these items were not consistent across replicate groups; (2) Even when there was a consistent gender difference in both replication groups, the magnitude was small; (3) When all of the differences were summed across items, bias in total scale score was minimal because the direction of the biases differed across items and so cancelled out and; (4) A small gender difference may exist in preferences for demonstrations of affection. Findings suggest that there are not substantial gender bias or scale equivalence problems with the DAS. The construct of dyadic adjustment was similar in men and women. These findings are congruent results from the recent study of South and Kruger (2009) on gender differences in the factor structure on the DAS and lend support to the valid use of the DAS in studies of dyadic adjustment.

Show moreThe purpose of this study was to investigate the potential effects of technology and personality on training using a computer based learning environment designed to improve learning through technology-delivered instruction. Data were collected from a sample of undergraduate students (N = 98), recruited from three universities (two in the US and one in Canada), who participated in both experimental days. Condition had no effect on learning outcomes, while Conscientiousness was found to be significantly correlated with academic performance. In further analyzing the relationship between personality and learning outcomes across time using a latent growth curve model results showed non-significant conclusions for the direction of the relationship for each of the Big Five. Discussion of the results and implications for practice and future research are provided. In conclusion, this study provides a basis for considering personality characteristics when designing computer-based training interventions in organizational settings.

Show moreHuman norovirus is a leading cause of foodborne outbreaks around the world especially in fresh-cut products like romaine lettuce. Traditional sanitizers such as sodium hypochlorite have been used in food industry to prevent contamination; however there are certain issues such as residuals and toxicity. Novel organic sanitizers have been developed and most of them have been proved not effective on human norovirus. High- Power-Ultrasound (HPU) has a potential to improve effectiveness of sanitizers for washing of fresh-cut produce. As a novel technology, HPU is a non-thermal processing that can enhance inactivating microorganisms in food. In the present study, we have systematically investigated the effect of sanitizers, Chico-wash, ProduceShield, Tsunami 100, EatCleaner and chlorine on human norovirus surrogate and the effect of HPU to enhance viral inactivation. For washing study, romaine lettuce leaves were cut into 5x5 cm2 pieces and spotinoculated with approximately 7 log PFU/ml of MNV-1. The leaves were washed for 60s, 90s, and 120s using various sanitizer concentrations. After washing, leaves were transferred into a stomach bag that contained 20ml of Dulbecco's modified eagle medium (DMEM) or phosphate buffer solution (PBS) containing 0.5M sodium thiosulfate to neutralize the sanitizers. Viruses were extracted by stomaching and recovered from the samples and quantified by viral plaque assay. Water wash without sanitizer was used as a negative control. For water wash, 1.1± 0.1 log PFU/g, 1.3 ± 0.1 log PFU/g and 1.3 ± 0.1 log PFU/g reduction were observed respectively under 60s, 90s and 120s washing.For 20% Chico-wash, under three different time intervals, MNV-1 reductions of 1.2 ± 0.1 log PFU/g, 1.1± 0.1 log PFU/g and 1.2 ± 0.2 log10 PFU/g were observed respectively. While for ProduceShield, at 20% concentration level, 1.5 log PFU/g, 1.6 log PFU/g and 1.6 log PFU/g reduction were observed respectively. For Tsunami 100, leaves were washed for 60s at different concentrations of 20, 40, 60, 80 and 100 ppm, the reduction of MNV-1 was 2.1 ± 0.2, 2.9 ± 0.3, 3.2 ± 0.3, 3.7 ± 0.2 and 3.7 ± 0.2 log PFU/g, respectively, on the surface of lettuce leaves. In HPU study, a high power ultrasound was introduced into washing step in combination with Tsunami 100 at concentrations of 20, 40, 60, 80, 100 ppm. The reduction of MNV-1 was 2.7 ± 0.3, 2.9 ± 0.5, 3.3 ± 0.7, 3.6 ± 0.7 and 3.8 ± 0.5 log10 PFU/g, respectively. For EatCleaner, lettuce leaves were washed for 60s and the reduction of MNV-1 was 1.9 ± 0.1 log10 PFU/g.The results suggest that Chico-wash and ProduceShield were not effective on removing MNV-1 from romaine lettuce while EatCleaner was effective. Tsunami 100 was effective on MNV-1. One-way ANOVA shows that introducing HPU could enhance MNV-1 inactivation at low Tsunami 100 concentration.

Show moreA knowledge-based system (KBS) was designed for automated system identification, process monitoring, and diagnosis of sensor faults. The real-time KBS consists of a supervisory system using G2 KBS development software linked with external statistical modules for system identification and sensor fault diagnosis. The various statistical techniques were prototyped in MATLAB, converted to ANSI C code, and linked with the G2 Standard Interface. The KBS automatically performs all operations of data collection, identification, monitoring, and sensor fault diagnosis with little or no input from the user. Navigation throughout the KBS is via menu buttons on each user-accessible screen. Selected process variables are displayed on charts showing the history of the variables over a period of time. Multivariate statistical tests and contribution plots are also shown graphically. The KBS was evaluated using simulation studies with a polymerization reactor through a nonlinear dynamic model. Both normal operation conditions as well as conditions of process disturbances were observed to evaluate the KBS performance. Specific user-defined disturbances were added to the simulation, and the KBS correctly diagnosed both process and sensor faults when present.

Show moreIn the near future, vehicular ad hoc networks (VANETs) are expected to be more widely deployed, where vehicles would be equipped with on-board devices that permit wireless networking between vehicles on the road, and between vehicles and in- frastructure. To ensure security and privacy, digital signature and veri cation schemes have been extenstively developed. The group signature implemented in VANETs causes large computation overhead, While the On Board Units installed on vehicles have limited CPU computing capacity. To address this issue, a practical cooperative message authentication protocol (CMAP) is designed and simulated in this work. In the protocol, vehicles share their veri cation results with each other in a cooperative way so that each vehicle just needs to verify a small number of messages. Compared with other work considering 1-D highway road scenario, 2-D city road scenario is built with the tra c simulator VanetMobiSim. Our CMAP simulation is based on the basic Periodic BroadCast (PBC) platform available in newer versions of ns-2 system. The protocol design and all detailed procedures of CMAP algorithms are implemented in the network simulator ns-2 with C++ programming. The simulation also evaluates the performance of CMAP with metrics including missed detection ratio, CPU load, under conditions of di erent vehicle densities and di erent numbers of veri ers. The performance of our CMAP with n-nearest veri er selction method is compared with previously reported probabilistic veri cation method, and shows the advantage.

Show moreThe indium monoiodide (InI) semiconductor is a promising candidate for Gamma-ray and X-ray radiation detector devices. The high atomic number of indium (In) and iodine (I), along with high density, give the InI detector a higher photon stopping power (attenuation coe cient) compared to germanium based detectors and comparable to that of CdT e. Based on the previous research on melt synthesis and vapor synthesis by Dr. Ostrogorsky at Rensselaer Polytechnic Institute (RPI) and Dr. Burger at Fisk University from 2006 to 2009, the present work improves the purity of indium monoiodide by demonstrating the e ciency of zone re ning of this material. A segregation coe cient study is presented based on a Glow Discharge Mass Spectrometry (GDMS) and an Instrumental Gas Analysis (IGA) analyses performed by Evans Analytical Group (EAG). Two indium monoiodide crystals were grown using the Vertical Bridgman technique and analyses done on one of the crystals shown a resistivity of 3 109 .cm which is the second highest value reported. Indium monoiodide synthesized and puri ed in this current study was used to grow several Czochralski crystals.

Show moreReal-time supervision of batch operations during the progress of a batch run offers many advantages over end-of-batch quality control. Process monitoring, quality estimation, and fault diagnosis activities are automated and supervised by embedding them into a real-time knowledge-based system (RTKBS). Interpretation of multivariate charts is also automated through a generic rule-base for efficient alarm handling and fault diagnosis. Multivariate statistical techniques such as multiway partial least squares (MPLS) provide a powerful modeling, monitoring, and supervision framework. Online process monitoring techniques are developed and extended to include predictions of end-of-batch quality measurements during the progress of a batch run. The integrated RTKBS and the implementation of MPLS-based process monitoring and quality control are illustrated using a fed-batch penicillin production benchmark process simulator.

Show moreCow’s milk allergy is one of the most prevalent food allergies in the United States. Commercial ELISA test kits, based on antigen-antibody reactions, are increasingly used by food manufacturers to detect the presence of allergen residues. Milk is a common ingredient used in a variety of foods that are subjected to different degrees of cooking. How thermal processing may affect the quantitative analysis of milk allergens by ELISA test kits needs to be determined. This study first examined the performance of four total protein assays (Pierce 660nm, Modified Lowry, Coomassie, BCA) for quantification of protein residues in thermally processed milk. BCA and Lowry assays were affected by lactose and its Maillard reaction byproducts resulting in the overestimation of protein concentrations in the samples. Pierce 660 nm assay was not affected and therefore was picked as the method for total protein analysis when evaluating commercial ELISA kits. Performances of four ELISA test kits (Veratox for Total Milk Allergen, BioKits BLG Assay Kits, ELISA SYSTEMS Casein and Beta-Lactoglobulin Residue assays) in comparison with the Pierce 660 nm assay for detection of thermally treated milk samples was also evaluated. NIST non-fat milk powder standard reference material 1549 and Backpacker’s Pantry Powdered Whole Milk were either heated in water at 60◦C, 63◦C, boiled, or autoclaved for 10 or 30 min, dry-heated in a mini-oven at 100 - 232◦C for 10 min, or fried in corn oil at 150◦C or 180◦C for 3 min in a deep fryer. Milk proteins in the oil samples were analyzed either directly or after extraction with phosphate-buffered saline with 0.05% Tween (PBST) followed by partitioning in hexane to remove residual oil. The results show that all four ELISA test kits were able to accurately quantify the amount of milk proteins in uncooked oils. Inclusion of the PBST/hexane extraction step prior to test kit analyses did not improve the detection. Elevated heat resulted in a lower level of proteins extracted. While the amount of protein residues determined by Veratox and ELISA SYSTEMS Casein kits were similar to those obtained by the Pierce assay, the BioKits BLG kits registered the highest amount of proteins in samples. On the other hand, ELISA SYSTEMS Beta-Lactoglobulin assay registered the lowest level of proteins in these samples. These results suggest that heat treatment could affect the solubility and possibly the antigenic properties of proteins. Depending on the test kits used, these changes could result in over- or underestimation of protein residues in thermally treated foods.

Show moreOutbreaks of human norovirus are commonly attributed to fresh produce and multi-ingredient foods that have received significant handling immediately prior to consumption. The objective of this study was to evaluate the effect of gloved and ungloved hands on norovirus transfer during fresh produce preparation. The palm and fingers of bare or gloved (polyvinyl, vinyl or nitrile) hands were inoculated with approximately 7-log PFU/hand murine norovirus (MNV-1). Freshly chopped Romaine lettuce was handled by the contaminated hands, and then sampled to determine the transfer coefficient. MNV-1 transfer was also measured from chopped contaminated lettuce to clean bare or gloved hands. In addition, pulsed light was investigated, in a preliminary study, for its ability to inactivate MNV-1 on the surface of food contact surfaces including the various glove types and Romaine lettuce, and thus prevent the spread of contamination. Transfer of MNV-1 occurred more readily to (up to 45%) Romaine lettuce than from (less than 12%) it. Transfer to Romaine lettuce was greater (p<0.05) from vinyl gloves than bare hands and the other glove types tested, while no significant difference (p>0.05) in transfer from lettuce to the different glove types was observed. The results indicate that norovirus transfer can occur readily in a food service setting, and that transfer coefficients are affected by the type of surfaces involved. MNV-1 was reduced by pulsed light by >4-log within 30 sec on all surfaces except nitrile gloves, indicating the potential for this technology to be employed in a food service setting to control the spread of noroviruses during food preparation.
