Examining the Interactive Effects of Group Status and Perceived Morality on Personality Judgments
We have a tendency to show a preference towards those who are most similar to ourselves. Most commonly, these biases feed into the perceived ideas that those similar to us (the in-group) are good and that those different from ourselves (the out-group) are bad (Rosenbaum & Holtz, 1985). In addition, Ruthland et al. (2010) demonstrated that the morality bias (i.e., preferring those that are good) often is stronger than the group bias (i.e., preferring the in-group); that is, moral preference is given priority over group membership. We sought to understand the interaction between how Christian participants perceive and rate individuals varying in group status (Christianity: in-group vs. Muslim: out-group) and morality (good vs. bad). The 118 participants were assigned to one of four conditions: moral/in-group, immoral/in-group, moral/out-group, and immoral/out-group. They completed a series of religious questionnaires, including quest religiousness, which is the perception of religion as a journey. Those who endorse quest religiousness indicate that they have a high tolerance for religious doubt and uncertainty. The participants were presented with descriptions of a fictitious individual that matched their condition and rated the individual on personality descriptor and interests to interact. A main effect revealed a preference for moral over immoral targets. However, a significant three-way interaction between quest religiousness, target morality, and group status revealed that when rating moral individuals, those high in quest religiousness rated the out-group member more favorably, and those low in quest religiousness rated the in-group member more favorably. This interaction indicates that a potential reverse of in-group bias occurs in those who view religion as a quest: such individuals rate more favorably those who are moral and religiously dissimilar than those who are moral and religiously similar
The Effect of Trait Death Anxiety on Job Involvement, Organizational Citizenship Behavior, and Turnover Intentions in Low Mortality Cue Jobs
Indiana University-Purdue University Indianapolis (IUPUI)Death anxiety is a concept that has received little empirical attention in the organizational psychology literature. Research has found that trait death anxiety is associated with burnout, and lower work engagement in jobs with high mortality cues. However, most people do not work in jobs where they are constantly reminded of death. The present study sought to examine the effects of trait death anxiety on employees working in low-mortality cue jobs. Using terror management theory as a foundation, I predicted that those higher in trait death anxiety would be more involved in their jobs, resulting in higher levels of organizational citizenship behavior and lower turnover intentions. In addition, I hypothesized that the relationship between trait death anxiety and job involvement will be moderated by need for achievement. This model was tested using a two time-point study, utilizing participants from Amazon’s Mechanical Turk. Results revealed a positive relationship between death anxiety and job involvement, and a negative relationship between death anxiety and turnover intentions mediated by job involvement. However, no significant relationships were found in regards to organizational citizenship behavior or need for achievement. Implications, limitations, and future directions are discussed
Avian Foods, Foraging and Habitat Conservation in World Rice Fields
Worldwide, rice (Oryza sativa) agriculture typically involves seasonal flooding and soil tillage, which provides a variety of microhabitats and potential food for birds. Water management in rice fields creates conditions ranging from saturated mud flats to shallow (\u3c30 cm) water, thereby attracting different guilds of birds. Grain not collected during harvest (i.e. waste rice) is typically the most abundant potential food of birds in rice fields, with estimates of seed mass from North America ranging from 66-672 kg/ha. Although initially abundant after harvest, waste rice availability can be temporally limited. Few abundance estimates for other foods, such as vertebrate prey or forage vegetation, exist for rice fields. Outside North America, Europe and Japan, little is known about abundance and importance of any avian food in rice fields. Currently, flooding rice fields after harvest is the best known management practice to attract and benefit birds. Studies from North America indicate specific agricultural practices (e.g. burning stubble) may increase use and improve access to food resources. Evaluating and implementing management practices that are ecologically sustainable, increase food for birds and are agronomically beneficial should be global priorities to integrate rice production and avian conservation. Finally, land area devoted to rice agriculture appears to be stable in the USA, declining in China, and largely unquantified in many regions. Monitoring trends in riceland area may provide information to guide avian conservation planning in rice-agriculture ecosystems
The Effects of Threats to Meaning on Attitudes Toward Evolution
Humans have an innate need to make sense of the world and give it meaning (Heine, Proulx, & Vohs, 2006), and do so by creating and defending cultural worldviews (Solomon, Greenberg, & Pyszcynski, 2004). Threats to meaning cause existential anxiety, and to protect ourselves from this existential fear, we reject, eliminate, or avoid threats to our cultural worldviews (Schmeichel & Martens, 2005). In addition, following threats to meaning, we compensate by showing aggression towards those who are dissimilar (Rosenblatt, Greenberg, Solomon, Pyszczynski, & Lyon, 1989). Science and religion are two prominent cultural worldviews that can provide meaning. We predict that following a meaning threat, participants high in religious fundamentalism would report a less favorable attitude toward evolution than those low in religious fundamentalism. Sixty introductory self-identified religious students at Hope College participated in this study. Participants first completed a measure of religious fundamentalism. They were then randomly assigned to complete a writing task based on condition: meaning challenge (writing about life’s lack of meaning), meaning affirmation (writing about how they find meaning in life), or neutral (writing about their plans for next week). Finally, they read an essay that presented mixed evidence about evolution and rated the essay and their views on evolution. Data were analyzed using an ANOVA examining the interaction between religious fundamentalism and priming condition on attitudes toward evolution. We found a significant interaction showing that religious fundamentalists were more critical of evolution when their meaning was challenged. Given that religious fundamentalists have been found to hold negative attitudes toward evolution (Poling & Evans, 2004), meaning threats may enhance these negative attitudes as a way of regaining meaning. These results highlight that individuals bolster different sources of meaning that are aligned with their values
Incidental Captures of Plains Spotted Skunks in Central South Dakota
The plains spotted skunk (Spilogale putorius interrupta) had a historically broad distribution in the central United States, extending from the Mississippi River west to the Rocky Mountains. This subspecies of the eastern spotted skunk (S. putorius) has experienced population declines in recent decades possibly due to habitat loss and reduction of prey through conversion of grasslands and forests to croplands, as well as reductions in abandoned buildings, fence rows, creek bottoms, and wood piles throughout the region (Crabb 1948, Kaplan and Mead 1991, Gompper and Hackett 2005, Sasse 2017). Woody debris provides access to prey, and a dense understory and overhead cover provide camouflage and protection from avian predators (Lesmeister et al. 2013, Eng et al. 2018). Overharvest, disease, pesticide use, and expanding or increasing predator populations might also have contributed to population declines (Gompper and Hackett 2005, Gompper 2017). Because the plains spotted skunk is currently under consideration for federal protection under the Endangered Species Act (U.S. Fish and Wildlife Service 2012), it is important to communicate new information on abundance, distribution and ecology of the subspecies. Furthermore, limited data exist on incidental captures of plains spotted skunks by researchers and state agencies (Diggins et al. 2015, Sasse 2018). Data collected through live-capture and non-invasive techniques are needed to improve the effectiveness of management and the understanding of this subspecies (Hackett et al. 2007)
Application strategy for an anthraquinonebased repellent and the protection of soybeans from Canada goose depredation
Agricultural crops can sustain extensive damage caused by Canada geese (Branta canadensis) when these crops are planted near wetlands or brood-rearing sites. From 2000 to 2015, South Dakota Game, Fish and Parks spent \u3e$5.6 million to manage damages caused by Canada geese to agricultural crops (primarily soybeans) in South Dakota, USA. For the purpose of developing a repellent application strategy for nonlethal goose damage management, we comparatively evaluated the width of anthraquinone applications (i.e., 9.4 L Flight Control® Plus goose repellent/ha [active ingredient: 50% 9,10-anthraquinone] at 0–36 m versus 0–73 m perpendicular to the edge of wetlands in 2014), the timing of the first repellent application (i.e., 9.4 L Flight Control Plus goose repellent/ha at 50% versus 75% seedling emergence in 2015), the yield of soybeans (Glycine max) within repellent-treated and untreated subplots, and anthraquinone chemical residues in Day County, South Dakota. Soybean yield was greater in subplots 73 m from the water’s edge than that in the 36-m subplots (P \u3c 0.02). Among subplots first sprayed at 50% seedling emergence, soybean yield was greater at 73 m and 82 m than that at 36 m (P \u3c 0.005). In contrast, we observed no difference in yield at 36 m, 73 m, or 82 m in the subplots first sprayed at 72% seedling emergence (P \u3e 0.09). We therefore conclude that goose damages were effectively managed in subplots first sprayed at 72% seedling emergence. Anthraquinone residues averaged 674 and 629 ppm anthraquinone upon the first application of the repellent (June to July), 22 and 35 ppm anthraquinone in the mid-season hay (August to September), and 36 and 28 ppb anthraquinone in the harvested seed (October to November) in 2014 and 2015, respectively. Our results suggest that a 73-m bandwidth of anthraquinone-based repellents first applied at approximately 72% or 65–85% seedling emergence can protect soybeans from Canada goose depredation
