Recruiting employees to work in teams: The impact of perceptions, KSAs, and recruitment source on pre-hire recruitment variables
Teams perform essential roles in many modern organizations and are therefore the tied to organizational success. The purpose of the current study was to examine the recruitment of employees to work in teams through an investigation into the impact of perceptions of teams, teamwork KSAs, and recruitment source on pre-hire recruitment variables in team and individual positions. A 2 x 3 repeated measures design presented participants with team and individual job postings on three online recruitment sources (organizational websites, online site visits, and referrals). Results support the idea that perceptions of teams do influence pre-hire recruitment variables to team and individual positions. However, relationships were not observed between teamwork KSAs and pre-hire recruitment variables with the exception of perceptions of organizational honesty. Furthermore, results indicated that differences do exist between recruitment sources with organizational websites leading to higher per-hire recruitment variables than online site visits and referrals
Perceived Work Life Balance: Exploring the Influence of Cultural Experience on Work Life Balance Perceptions
Much like the typical employee, college students are often involved in a multitude of activities beyond the classroom that make maintaining work life balance challenging. Research suggests that cultural exposure may influence an individual’s quality of work life perceptions. The present study aims to explore the impact of cultural experience, such as study abroad and international partner conversations, on the individual’s perception of their work life balance and the work life balance of others. Participants will first provide information regarding current work life balance, and cultural exposure, then they will be presented with employee vignettes, and finally, they will report their satisfaction with the work life balance of each employee’s situation as well as their own. Results will contribute to the field by investigating the relationship between cultural exposure and perceptions of work life balance in order to facilitate the recruitment and selection process. It is essential for organizations to understand and be aware of the impact that cultural experience can have on individuals to ensure that a potential employee’s work life balance values align with the values of the organization. By doing so, organizations will be able to offer positions to individuals that are best suited, while also matching applicants to appealing work life balance opportunities
A Valid Analysis of a Small Subsample: The Case of Non-Citizen Registration and Voting
The development of large sample surveys creates new opportunities for analysis of subpopulations that would hitherto have been impossible to examine systematically. But it also raises key challenges. Low level measurement error can potentially lead to substantial biases in estimates drawn from small subsamples. This study details strategies researchers may take to make inferences in the context of this subsample-response-error problem. In the non-citizen voting case, which recently has received substantial attention, we show that attention to any of these strategies -- group-specific response error estimates, correlated higher-frequency events, test-retest validity, or analysis of associated hypotheses – produces significant evidence that non-citizens participated in recent US elections. This reaffirms the validity of the core claim made by Richman, Chattha, and Earnest (2014): a small percentage of non-citizens vote in US elections
Learning from Small Subsamples without Cherry Picking: The Case of Non-Citizen Registration and Voting
The development of large sample surveys creates new opportunities for analysis of subpopulations that would hitherto have been impossible to examine systematically. But it also raises key challenges. Low level measurement error can potentially lead to substantial biases in estimates drawn from small subsamples. This study details strategies researchers may take to make inferences in the context of this subsample-response-error problem. In the non-citizen voting case, which recently has received substantial attention, we show that attention to any of these strategies -- group-specific response error estimates, correlated higher-frequency events, or test-retest validity – produces significant evidence that non-citizens participated in recent US elections. Additional hypotheses that follow from the measurement error assumption are also not supported. We identify future steps to improve the reliability of estimates through in-survey test-retest in order to facilitate accurate sub-population identification for analyses
In vivo comparative study of ocular vasodilation, a relative indicator of hyperemia, in guinea pigs following treatment with bimatoprost ophthalmic solutions 0.01% and 0.03%
Abayomi B Ogundele, David Earnest, Marsha A McLaughlinAlcon Research, Limited, Fort Worth, TX, USAObjective: The objective of this in vivo study was to compare the incidence of vasodilation in guinea pigs following topical administration of bimatoprost ophthalmic solutions 0.01% and 0.03%.Methods: The study comprised 20 guinea pigs assigned to 2 treatment groups (10 per treatment group) to receive either bimatoprost 0.01% or bimatoprost 0.03%. Animals were hand-held under 2.75 × magnification to score ocular vasodilation (a measure of hyperemia), using a scoring system developed at Alcon Research, Ltd. Following baseline ocular scoring, each animal received a 30 μL dose to the left eye of either bimatoprost 0.01% (3 μg) or bimatoprost 0.03% (9 μg). Vasodilation was again scored at 1, 2, 3, 4, 5 and 6 hours after dosing. Incidence of vasodilation was calculated as the percent of total eyes in each 2-hour time interval with scores ≥2.Results: The incidence of vasodilation was higher in the bimatoprost 0.01% treatment group (range, 45.0% to 60.0%) than the bimatoprost 0.03% treatment group (range, 30.0% to 52.2%) at all post-dosing time points.Conclusion: The 2 bimatoprost formulations elicited ocular vasodilation of long duration (>6 hours) in the guinea pig model, with the bimatoprost 0.01% treatment group showing a higher incidence of ocular vasodilation than the bimatoprost 0.03% treatment group. Further clinical studies would be needed to determine whether the higher incidence of vasodilation may also be attributed to the increased BAK concentration in the bimatoprost 0.01% formulation.Keywords: bitamoprost, ocular vasodilation, hyperemi
Chemostratigraphy and depositional environment of an Ordovician sedimentary section across the Miramichi Group - Tetagouche Group contact, northeastern New Brunswick
A thick section of Ordovician sedimentary rocks underlies and overlies felsic to mafic volcanic rocks of the Tetagouche Group, Bathurst Mining Camp. The dark grey quartzose slates and siltstones of the Patrick Brook Formation (Miramichi Group) occur below the volcanic rocks, whereas the dark grey to black slates and siltstones of the Boucher Brook Formation (Tetagouche Group) are intercalated with the volcanic rocks and overlie the sequence. The Miramichi-Tctagouche contact represents the interpreted Gander-Dunnage boundary in northeastern New Brunswick. Distinguishing between these two simitar formations is important for stratigraphic and geo-tectonic interpretations of the Bathurst Mining Camp and for exploration in these sequences. The geochemical composition of a semi-con form able section of rocks from the Boucher Brook (Middle to Late? Ordovician) and Patrick Brook (Early to Middle Ordovician) formations was determined to identify geochemical chemostratigraphic discriminants, as well as to determine the depositional environment in which these were deposited.
The high AI2O3 and distinctly higher high-field-strength elements (LREE, Th, HREE, and Y) in the Patrick Brook rocks are characteristic of mature sedimentary rocks and indicate intense chemical weathering (tropical environment) in the source regions, which is consistent with their compositional similarity to Avalon-derived shales analogous to Gander Zone sedimentary rocks. The Boucher Brook slates and siltstones are immature sedimentary rocks based on the preservation of albite and the less coherent trace-element systematics to phyllosilicate indices (AI2O3 and K2O). The Boucher Brook Formation is probably derived from the associated volcanic rocks.
The higher Mn and Fe and positive Ce/Ce* anomaly in some Boucher Brook Formation compared to the Patrick Brook rocks indicate that the Boucher Brook rocks in this section were deposited in a transitional anoxic/ oxic environment. The Patrick Brook rocks that immediately precede felsic volcanism and formation of massive sulphide deposits are highly reduced based on C and S contents, which is consistent with the sulphur isotope data. Moderately heavy δ34S values are indicative of SO42- reduction to H2S under anoxic conditions, which is significant in the formation and preservation of massive sulphides in the basal Tetagouche sequence.
RÉSUMÉ
Une section épaisse de roches sédimentaires de l’Ordovicien est sus-jacente ct sous-jacente à des roches volcanomafiques à volcanofelsiques du groupe de Tetagouche, dans le Camp minier de Bathurst. Des siltstones et des schistes quartzeux gris foncé de la Formation de Patrick Brook (groupe de Miramichi) sont présents au-dessous des roches volcaniques, tandis que des schistes et des siltstones gris foncé à noirs de la formation de Boucher Brook (groupe de Tetagouche) sont intercales dans les roches volcaniques et recouvrent la séquence. La surface de contact de Miramichi-Tetagouche représente ce qu'on interprèts comme la limite de Gander-Dunnage dans le nord-est du Nouveau-Brunswick. Il est important d'établir une distinction entre ces deux formations semblables pour les interprétations stratigraphiques du Camp minier de Bathurst et pour l'exploration dans ces séquences. On a détermine la composition géochimique d'une section semi-concordante de roches de Boucher Brook (Ordovicien moyen à tardif?) et de Patrick Brook (Ordovicien inférieur à moyen) afin de repérer les discriminants chimiostratigraphiques géochimiques ainsi que pour définir le milieu sédimentaire dans lequel ceux-ci ont été deposes.
La quantité prononcée d'Al2O3 et la présence distinctement supérieure d'éléments d'intensité de champ élevée (éléments de terres rares légers, Th, éléments de terres rares lourds et Y) dans les roches de Patrick Brook constituent des traits caractérstiques de roches sédimentaires matures; el les témoignent d'une altération climatique chimique intense (milieu tropical) dans les regions d'origine, ce qui est compatible avec la similarité de leur composition avec les schistes en provenance d'Avalon analogues aux roches sédimentaires de la zone de Gander. Les schistes et les siltstones de Boucher Brook sont des roches sédimentaires immatures basées sur la conservation d'albite et la corrélation d'éléments traces moins cohérents avec les indices de phyllosilicates (AI2O3). La Formation de Boucher Brook provient probabtement de roches volcaniques connexes.
La proportion supérieure de Mn et de Fe et l’anomalie positive de Ce/Ce* dans certaines parties de la Formation de Boucher Brook révèlcnt que les roches de Boucher Brook de cette section ont été déposées dans un milieu anoxique / oxique de transition. Les roches de Patrick Brook qui ont immédiatement précedé le volcanisme felsique et la formation de gitcs de sulfures massifs ont, à en juger par Icur teneur en C et en S, subi une réduction importante, ce qui correspond aux données isotopiques relatives au soufre. Les valeurs moyennement prononcées de δ34S temoignent d'une réduction du SO42- en H2S dans des conditions anoxiques, un phénomène déterminant dans la formation et la conservation des sulfures massifs dans la séquence basale de Tetagouche.

Morality in Gaming: Observer Perceptions of Player versus Character Actions
The debate on the impact of violent video games and its influence on players continues despite mixed findings. Using the lens of third person perception research, we explored moral judgments of laypersons, those often at the crux of these public debates. Study 1 investigated whether the player or character is perceived by an outside observer as responsible for moral decisions made within the narrative of a violent video game. Study 2 investigated how those perceptions may impact the observers’ perceptions of the player’s future negative behaviors and personality traits. Study 1 and 2 used a 2 (condition: rescuing vs. harvesting) x 2 (role: player vs. character) mixed ANOVA with role as a repeated measure. We created a brief recording of gameplay leading to a moral decision in Bioshock, an interactive, first-person shooter game, shown to participants. Participants were asked to rate perceived morality of player and character actions. Study 1 showed that participants (N = 51) held the observed player more morally responsible for in-game behaviors than the character within the game. Replicating and advancing Study 1, Study 2 (N = 227) showed support for you are what you eat heuristic, in that observers were more likely to view the negative behaviors of the in-game characters as indicators of negative personality traits of the player. These insights are crucial in the broader societal discourse on the potential link between violent video games and real-world aggressio
Do Non-Citizens Vote in U.S. Elections?
In spite of substantial public controversy, very little reliable data exists concerning the frequency with which non-citizen immigrants participate in United States elections. Although such participation is a violation of election laws in most parts of the United States, enforcement depends principally on disclosure of citizenship status at the time of voter registration. This study examines participation rates by non-citizens using a nationally representative sample that includes non-citizen immigrants. We find that some non-citizens participate in U.S. elections, and that this participation has been large enough to change meaningful election outcomes including Electoral College votes, and Congressional elections. Non-citizen votes likely gave Senate Democrats the pivotal 60th vote needed to overcome filibusters in order to pass health care reform and other Obama administration priorities in the 111th Congress
Effects of tegaserod on bile composition and hepatic secretion in Richardson ground squirrels on an enriched cholesterol diet
BACKGROUND: Tegaserod is effective in treating IBS patients with constipation, and does not alter gallbladder motility in healthy individuals or in patients with IBS. However, it is not known if tegaserod affects the biliary tract in gallstone disease, so to this end the effects of tegaserod on bile composition and hepatic secretion of Richardson ground squirrels maintained on an enriched cholesterol diet were examined. RESULTS: Animals were fed either a control (0.03%) or enriched (1%) cholesterol diet for 28 days, and treated s.c. with tegaserod (0.1 mg/kg BID) or vehicle. Bile flow, bile acid, phospholipids and cholesterol secretion were measured with standard methods. Tegaserod treatment or enriched cholesterol diet, alone or combination, did not alter body or liver weights. The enriched cholesterol diet increased cholesterol saturation index (CSI), cholesterol concentrations in gallbladder and hepatic duct bile by ~50% and decreased bile acids in gallbladder bile by 17%. Tegaserod treatment reversed these cholesterol-induced changes. None of the treatments, drug or diet, altered fasting gallbladder volume, bile flow and bile salts or phospholipid secretion in normal diet and cholesterol-fed animals. However, tegaserod treatment prevented the decreases in bile acid pool size and cycling frequency caused by the enriched cholesterol diet, consequent to re-establishing normal bile acid to concentrations in the gall bladder. Tegaserod had no effect on these parameters with normal diet animals. CONCLUSION: Tegaserod treatment results in increased enterohepatic cycling and lowers cholesterol saturation in the bile of cholesterol-fed animals. These effects would decrease conditions favorable to cholesterol gallstone formation
