Game-Framing Cognitive Assessments to Improve Applicant Perceptions

GAME-FRAMING COGNITIVE ASSESSMENTS TO IMPROVE APPLICANT PERCEPTIONS Andrew Burnett Collmus Old Dominion University, 2016 Director: Dr. Richard N. Landers Research has shown that although cognitive testing is key to quality hiring, applicants often react poorly to cognitive ability tests. Applicant reactions theory indicates that time-length judgments of a selection procedure can affect applicant perceptions. It was thus hypothesized that game-framing, the act of labeling something a game without changing the content, would cause participants to perceive that time was moving faster while completing a battery of cognitive ability tests. Similarly, it was expected that game-framing would increase test motivation and decrease test anxiety. Perceived length was tested as a mediator for the effects of game-framing on test anxiety and on test motivation. Structural equation modeling was used to evaluate the hypothesized relationships. In the observed dataset, game-framing caused decreases in perceived length, perceived length was positively related to test motivation, and perceived length mediated the relationship between game-framing and test motivation. The results of this study demonstrate that game-framing affects time perceptions. This finding has implications for gamification researchers, namely, that game-framing effects should be measured and accounted for in future studies. Furthermore, applicant reactions theorists have suggested that perceived time length is a key variable in the overall applicant reactions model, and this study is the first to empirically investigate perceived time length of a selection procedure in this context. Results indicate that perceived length may not relate to other applicant reaction variables as predicted by applicant reactions theory.
VARIABILIDADE ESPACIAL DAS PERDAS E DA RESISTÊNCIA MECÂNICA DO SOLO À PENETRAÇÃO NO ARRANQUIO MECANIZADO DE AMENDOIM

Mechanized peanut harvesting is of great importance in the crop production process but there are considerable losses, especially in the digging operation. The objective of this study was therefore to measure the spatial variability of peanut losses and soil mechanical resistance to penetration (RP) in the mechanized digging operation using two displacement speeds. The study was performed in the northern region of Sao Paulo State. Treatments consisted of two speeds (V1 = 3.5 km h-1 and V2 = 4.7 km h-1) and ten replications using a completely randomized design (DIC). After the digging the RP measurements were obtained using an electronic penetrometer positioned across peanut lines, taking measurements at every 0.01 m of depth to a maximum of 0.30 m deep, and at every 0.15 m in width to a total of 1.80 m. At the same points losses from digging were determined and classified as visible (PVA), invisible (PIA) and total losses (PTA). Speed of the tractor-digger did not influence the peanut losses evaluated or the RP. Soil mobilization occurred up to 0.13 m in depth and the level across the active parts of the digger was uneven. Correlations were observed between PVA and PIA, and between PTA and RP, but the determination coefficients (R²) were less than 25%.
Justice in Residency Placement: Is the Match System an Offense to the Values of Medicine?

Medical residency—specialty training after the completion of medical school—is an essential component of medical education and is required in order to be a licensed, independent medical practitioner in most jurisdictions. As things currently stand in the United States, the match between medical school graduates and residency programs is governed by a match between rank-order lists prepared by candidates and residencies alike. An applicant picks a number of residency programs and ranks them according to order of interest. The residency program prepares a similar list, ranking the candidates it most wants in its program. A computer program compares the rankings and makes assignments according to a certain algorithm. Using these lists, the match system assigns approximately 24,000 applicants to approximately 21,000 training positions in pediatrics, obstetrics and gynecology, internal medicine, and the rest. These assignments are then announced to all parties on specific days. The system has been in place since 1952 and is overseen by the National Residency Match Program (NRMP), a nonprofit organization. This system has several advantages. First of all, it standardizes the timetable for decisions, and applicants are in no position to tie up offers while waiting to hear from other institutions. Institutions are not held captive, either, in making assignments while waiting to hear from particular parties.
Late survival after abdominal aortic aneurysm repair.

OBJECTIVES This study was undertaken to determine the late survival of patients operated successfully for abdominal aortic aneurysm (AAA) repair, to compare survival data with that of the age- and sex-matched general population, to identify the causes of late death, and to determine the factors influencing late survival. MATERIALS AND METHODS A total of 187 consecutive patients underwent elective surgical AAA repair between January 1987 and December 1991. There were 11 postoperative deaths (early mortality rate 5.9%). The remaining 176 patients formed the basis of this cohort-based retrospective study. Six patients (3.4%) were lost to follow-up. Mean follow-up was 71 months. RESULTS A total of 70 patients (39.8%) died during the study period. Coronary artery disease (CAD) and cancer were the two main causes. The survival rate at five years (71.6%) was lower than that of the sex- and age-matched general population (90.6%). Neither arterial hypertension nor CAD had any influence on late survival. In contrast, age and chronic renal failure were predictive variables of late survival. CONCLUSIONS The life expectancy of patients who undergo successful AAA repair is not as good as that of the age- and sex-matched general population. Late survival depends on the patients' age at the time of surgery and the existence of preoperative chronic renal failure.
Repeat Purchase Intention of Starbucks Consumers in Indonesia: A Green Brand Approach

This study develops and tests the repeat purchase intention model (with a green brand approach). The model considers four determinants; perceived image, satisfaction, trust, and attitude. The model is tested using data and a survey of 203 Starbucks customers in Indonesia. The analysis was carried out by employing Structural Equation Modeling. The data was processed with AMOS 21. The results confirm that the company’s green brand image is positively and significantly related to consumer satisfaction, trust, and attitude. On the other hand, consumer satisfaction and trust are shown to have insignificant influence on repeat purchase intention.
Relationships between bone density values from cone beam computed tomography, maximum insertion torque, and resonance frequency analysis at implant placement: a pilot study.

PURPOSE The aim of the present study was to determine bone density in designated implant sites using cone beam computed tomography (CBCT) and to evaluate possible correlations between age, gender, insertion torque measurements, and resonance frequency analysis (RFA) values. MATERIALS AND METHODS Completely and partially edentulous patients were treated with implants between 2007 and 2008 and evaluated retrospectively. The preoperative examination included a panoramic radiograph, CBCT, diagnostic casts, and a clinical examination of the jaws. With the CBCT scans, bone densities were recorded in Hounsfield units (HU). Insertion torque values and implant stability measurements (via RFA) were also noted. RESULTS Mean bone density and insertion torque values were 623 ± 209 HU and 42.4 ± 4 Ncm, respectively, for the 82 implants placed. Mean primary stability (implant stability quotient) was 62.4 ± 8. The differences in mean bone density at implant sites in the mandible (717 ± 204 HU) and the maxilla (490 ± 128 HU) were statistically significant for all patients (P < .05). There was a statistically significant relationship between bone density values and insertion torque measurements for implant sites in the anterior mandible (r = 0.562, P < .05), as well as between bone density and RFA values for men (r = 0.412, P < .05). CONCLUSIONS Bone density measurements using preoperative CBCT may be helpful as an objective diagnostic tool. These values, in conjunction with RFA values and insertion torque measurements, can provide the implant surgeon with an objective assessment of bone quality and may be especially useful where poor-quality bone is suspected.
Pattern Analysis of Organizational Creativity Revelation Based on Agent-Based Modeling

Although there are many ways to increase organizational creativity, this study explores the issue of increasing organizational creativity by adopting the knowledge diversity and creativity revelation processes, which have been studied separately in the past but have not been analyzed together in a single research framework. The purpose of this research is to longitudinally investigate the evolutionary pattern of organizational creativity in order to explain how the knowledge diversity and creativity revelation processes - exploitation and exploration - affect organizational creativity. Experiments are used to show the validity of the research questions based on agent-based modeling (ABM) simulation. The results of the experiment confirm that knowledge diversity and exploitation/exploration positively affect organizational creativity. However, with a time factor entered into the simulation, the results show different patterns in the longer term in regards to the effects of exploitation/exploration.
Exercise‐induced Modulation of Antioxidant Defense

Maintaining mobility is a critical element for the quality of life. Skeletal muscle, the primary organ for locomotion, undergoes age‐associated deterioration in size, structure, and function. Recent research suggests that oxidative stress is an important etiology for sarcopenia. The level of oxidative stress imposed on aging muscle is influenced by two fundamental biological processes: the increased generation of reactive oxygen species (ROS) and age‐associated changes in antioxidant defense. It appears that despite increased ROS production, aging muscle has a decreased gene expression of antioxidant enzymes possibly due to a diminished ability for cell signaling. A major benefit of nonexhaustive exercise is to induce a mild oxidative stress that stimulates the expression of certain antioxidant enzymes. This is mediated by the activation of redox‐sensitive signaling pathways. For example, gene expression of muscle mitochondrial (Mn) superoxide dismutase is enhanced after an acute bout of exercise preceded by an elevated level of NF‐κB and AP‐1 binding. An increase in de novo protein synthesis of an antioxidant enzyme usually requires repeated bouts of exercise. Aging does not abolish but seems to attenuate training adaptations of antioxidant enzymes. Thus, for senescent muscle, training should be assisted with supplementation of exogenous antioxidants to research the optimal level of defense.
Regulation of the pituitary-specific transcription factor GHF-1/Pit-1 messenger ribonucleic acid levels by growth hormone-secretagogues in rat anterior pituitary cells in monolayer culture.

Pituitary-specific expression of the GH gene is dependent on a pituitary-specific transcription factor GH factor-1 (GHF-1), a homeodomain protein also known as pituitary-specific transcription factor-1 (Pit-1). The aim of this study was to investigate the regulation of GHF-1 messenger RNA (mRNA) levels in primary monolayer cultures of rat anterior pituitary cells. Specifically, in addition to direct activators of second messenger signaling systems, we studied the effects of different hormones, all of which are known to be involved in the regulation of somatotroph cell function. We found that GH-releasing hormone (GHRH) increased GHF-1 mRNA levels in a time- and dose-dependent fashion. GHF-1 mRNA levels were increased 2.5-fold (P < 0.01) after incubation for 2 h with 10(-8) M GHRH. Longer incubations (6, 12, or 24 h) with GHRH failed to show a similar stimulatory effect. A significant increase in GHF-1 mRNA concentration (1.7-fold, P < 0.01) was observed after a 2-h treatment with physiological concentrations (10(-11) M) of GHRH. The action of GHRH seems to occur at the transcriptional level without the need of protein synthesis. Thus, treatment of cells with actinomycin D (5 micrograms/ml) completely abolished GHRH-induced increase in GHF-1 mRNA levels. Cycloheximide (23 micrograms/ml) alone increased GHF-1 mRNA levels (6-fold increase after treatment for 12 h, P < 0.01), as well as potentiating GHRH-induced increase in GHF-1 mRNA concentration (9-fold increase after treatment with GHRH plus cycloheximide for 12 h, P < 0.01). The effect of GHRH on GHF-1 mRNA levels could be mimicked by direct activators of second messenger signaling systems such as forskolin (10(-5) M) or the phorbol ester tumor promoter tetradecanoyl phorbol acetate (TPA) (10(-6) M). Other peptides such as pituitary adenylate cyclase activating polypeptide-38 (10(-7) M) but not GHRP-6 (10(-10) to 10(-5) M), were also able to increase GHF-1 mRNA levels. Treatment of the cells with somatostatin (10(-6) M) for either 2 or 48 h failed to modify basal or GHRH-induced GHF-1 mRNA levels. In contrast, pretreatment of the cells with insulin-like growth factor-1 (5 nM) inhibited basal GHF-1 mRNA concentration as well as completely blunting the subsequent response to cells exposed to GHRH for 2 h. These data demonstrate that GHRH, acting at the transcriptional level and through a mechanism not dependent on protein synthesis, plays a stimulatory role on GHF-1 mRNA levels.

The ciliary GTPase Arl13b regulates cell migration and cell cycle progression

ABSTRACT The GTPase ARL13B is localized to primary cilia; small cellular protrusions that act as antennae. Its defective ARL13B hennin (HNN) variant is linked causally with Joubert Syndrome, a developmental ciliopathy attributed to poor sensing of extracellular chemical gradients. We tested the hypothesis that impaired detection of extracellular voltage gradients also contributes to the HNN phenotype. In vitro, extracellular electric fields stimulated migration of wild type (WT) and HNN fibroblasts toward the cathode but the field only increased the migration speed of WT cells. Cilia on WT cells did not align to the field vector. HNN cells divided more slowly than WT cells, arresting at the G2/M phase. Mechanistically, HNN cells had reduced phospho-ERK1/2 signaling and elevated levels of Suppressor of Fused protein. These suggest that cells may not be able to read extracellular chemical cues appropriately, resulting in deficits in cell migration and proliferation. Finally, an increase in tubulin stabilization (more detyrosinated tubulin) confirmed the general stagnation of HNN cells, which may further contribute to slower migration and cell cycle progression. We conclude that Arl13b dysfunction resulted in HNN cell stagnation due to poor growth factor signaling and impaired detection of extracellular electrical gradients, and that the role of Arl13b in cell proliferation may be understated.
Hepatic riboflavin and tumor formation in rat fed azo dyes in various diets.

I t is well recognized that rats fed p-dimethylaminoazobenzene (DAB) develop tumors at rates that depend upon the composition of the basal diet. Dietary factors reported to increase the rate of tumor formation under certain circumstances include biotin (2, 4), pyridoxine (16), cystine (18), and the rice bran concentrate "Vitab" (12, 13, 16). The dietary factors most effective in retarding tumor formation include riboflavin (8, 12, 16) and hydrogenated coconut oil (13, 14). The evidence for these effects has been summarized in a recent review (17). Later experiments, however, suggest that riboflavin may be more important in the development of hepatic tumors than most of the other dietary factors that have been studied. When m'methyl-p-dimethylaminoazobenzene (m'-Me-DAB) was fed as the carcinogen, the rate at which tumors developed was not increased by the feeding of the rice bran concentrate, nor did hydrogenated coconut oil exert any considerable retarding effect (6). Riboflavin, however, retarded the development of tumors due to the m-methyl dye, though not as much as when DAB was the carcinogen. Further evidence for a peculiar role of riboflavin in the formation of hepatic tumors is the observation that certain of the azo dyes markedly lower the hepatic concentration of this vitamin (7, 9) while chemically similar non-carcinogenic dyes do not (7). Indeed, there appears to be a rough correlation between the carcinogenic potencies of the various azo dyes and their effects upon the concentration of riboflavin in the liver in relatively short-term experiments (7). The question, therefore, arose whether diets known to alter the rate of hepatic tumor formation might not exert their effects primarily by modifying the ability of the liver to store riboflavin.
Fat mass is not beneficial to bone in adolescents and young adults.

CONTEXT Although muscle mass is beneficial to bone, studies on the effect of fat mass on bone have yielded conflicting results. OBJECTIVE The aim of this study was to assess the relations between lean and fat mass and bone structure. DESIGN This study was cross-sectional. SETTING The study was conducted in a general community. SUBJECTS Subjects included 300 healthy sexually mature adolescents and young adults (150 males and 150 females) between the ages of 13 and 21 yr. MAIN OUTCOME MEASURE We investigated the relation between dual-energy x-ray absorptiometry (DXA) measures of total body fat and lean mass and bone values obtained with DXA (legs and lumbar spine bone mineral density and bone mineral content) and computed tomography (CT) (cross-sectional and cortical bone areas of the femurs and cross-sectional area and cancellous bone density of the vertebrae). RESULTS Simple and multiple linear regression analyses showed significant positive relations between DXA lean mass and all CT and DXA measures of bone in the axial and appendicular skeletons (all P < 0.005). In contrast, whereas Pearson correlations between DXA measures of fat mass and bone parameters were generally positive, multiple regression analyses showed that fat mass, after accounting for lean mass, trunk height/leg length, had a negative, or no, correlation with CT and DXA values for bone. CONCLUSIONS Our findings provide compelling evidence that, despite increased mechanical loading and independent of lean mass, adipose tissue is not beneficial to bone structure.
GAMMA-RAY BURST LIGHT CURVES IN THE RELATIVISTIC TURBULENCE AND RELATIVISTIC SUBJET MODELS

Randomly oriented relativistic emitters in a relativistically expanding shell provide an alternative to internal shocks as a mechanism for producing gamma-ray bursts' variable light curves with efficient conversion of energy to radiation. In this model, the relativistic outflow is broken into small emitters moving relativistically in the outflow's rest frame. Variability arises because an observer sees an emitter only when its velocity points toward him so that only a small fraction of the emitters is seen by a given observer. Significant relativistic random motion requires that a large fraction of the overall energy is converted to random kinetic energy and is maintained in this form. While it is not clear how this is achieved, we explore here, using two toy models, the constraints on parameters required to produce light curves comparable to the observations. We find that a tight relation between the size of the emitters, and the bulk and random Lorentz factors is needed and that the random Lorentz factor determines the variability. While both models successfully produce the observed variability there are several inconsistencies with other properties of the light curves. Most of which, but not all, might be resolved if the central engine is active for a long time, producing a number of shells, resembling to some extent the internal shocks model.
Human Metapneumovirus Establishes Persistent Infection in Lung Microvascular Endothelial Cells and Primes a Th2-Skewed Immune Response

Human Metapneumovirus (HMPV) is a major cause of lower respiratory tract infections. HMPV infection has been hypothesized to alter dendritic cell (DC) immune response; however, many questions regarding HMPV pathogenesis within the infected lung remain unanswered. Here, we show that HMPV productively infects human lung microvascular endothelial cells (L-HMVECs). The release of infectious virus occurs for up to more than 30 days of culture without producing overt cytopathic effects and medium derived from persistently HMPV-infected L-HMVECs (secretome) induced monocyte-derived DCs to prime naïve CD4 T-cells toward a Th2 phenotype. Moreover, we demonstrated that infected secretomes trigger DCs to up-regulate OX40L expression and OX40L neutralization abolished the pro-Th2 effect that is induced by HMPV-secretome. We clarified secretome from HMPV by size exclusion and ultracentrifugation with the aim to characterize the role of viral particles in the observed pro-Th2 effect. In both cases, the percentage of IL-4-producing cells and expression of OX40L returned at basal levels. Finally, we showed that HMPV, per se, could reproduce the ability of secretome to prime pro-Th2 DCs. These results suggest that HMPV, persistently released by L-HMVECs, might take part in the development of a skewed, pro-Th2 lung microenvironment.
Dreams and schizophrenia.

Recalled nighttime dreams of 30 schizophrenic and 30 nonschizophrenic women were compared on parameters theoretically related to schizophrenia. Ten hypotheses concerning the reflection of the schizophrenic process in dreams were tested and 19 additional variables which qualified these hypotheses were compared. The study as a whole tested the general assumption that dream content is consistent with waking psychopathology or normalcy. Nine of the hypotheses were confirmed at high levels of significance. Qualitative categories also showed differences. Schizophrenic subjects thus displayed personality traits commonly associated with schizophrenia more often in their dreams than did nonschizophrenic subjects. In general, schizophrenic dreams gave the impression of an acute state of emergency or stress. Control dreams, depicting everyday, practical concerns, were far less traumatic.
