A 35-day feeding trial was conducted to evaluate growth, bacterial populations of the gastrointestinal tract (GIT) and immune responses of Litopenaeus vannamei fed diets containing the commercial prebiotic Previda. Diets were formulated to contain Previda at 0, 0.2, 0.5, 1.0 or 1.6 g kg 1 by weight. At the end of the study, differences in weight gain and survival among treatments were not significant (P u3e 0.05), but denaturing gradient gel electrophoresis analysis revealed that the microbial communities in the GIT changed significantly with the inclusion of dietary Previda at different levels. Previda was therefore able to selectively modify the microbial communities in the shrimp’s GIT. Although individual bacterial species were not identified, enteric populations in shrimp fed the prebiotic at similar levels of inclusion were genetically similar. In addition, shrimp fed Previda at 1.6 g kg 1 responded significantly (P u3c 0.05) better immunologically with respect to hemocyte phagocytic capacity, haemolymph protein, hyaline cell counts and haemolymph glucose compared with shrimp fed the basal diet. Although shrimp were not exposed to virulent pathogens in this study, the observed upregulation of some of immune responses upon prebiotic supplementation indicates that an improved outcome of such challenges may be anticipated in Previda-fed shrimp under commercial conditions

This report describes the development of a script programmed in the Python language designed to simulate radioactive decay using Monte Carlo methods. This is to conduct analysis on the equilibrium behavior of a specific radioactive decay chain, replacing the traditional method of deriving a mathematical representation via differential equations. The resulting script produces a stacked histogram illustrating the decay of Actinium-225 over time and more closely models the potential for irregularities in the natural phenomenon. The script has potential applications in nuclear imaging and medical physics

Career Development: A Human Resource Development Perspective offers a strategic framework that demonstrates the role of career development within the human resource function. It goes beyond conventional interventions and includes key topics such as diversity, work–life balance, and ethics. Historically, the career development literature has been viewed either from the perspective of the individual (how to build a career) or from an economic perspective (how an organization benefits from developing employees). In this book, McDonald and Hite bring together the strengths of both traditions, offering an integrated framework for career development. The theoretical foundation expands on the counseling literature by incorporating the literature from human resource development and related fields. The application section reflects on the wide range of ages and working options that characterize the current and future workplace. The final section of the book addresses career development issues such as managing a diverse, global workforce; ethics; and work–life balance. This book will help prepare human resource development students, scholars, and practitioners to develop and maintain successful career development programs, and to foster more innovative research that advances the discourse

Libraries are at the front and center of efforts to save and digitize local history collections. Working with community organizations to tap existing but not well understood collections can open doors to a wealth of undiscovered materials. Using the Girl Scouts of Northern Indiana-Michiana (GSNIM) archival collection as an example, we will discuss the challenges inherent in these collaborative efforts and strategies to employ when reaching out to new community partners. The GSNIM collection digitization project was funded via a LSTA grant and the collaboration of GSNIM, Mishawaka-Penn Harris Public Library (MPHPL), IPFW Helmke Library and various community volunteers. The collection can be found at: http://cmdm16066.contentdm.oclc.org/cdm/landingpage/collection/p16066coll2

The macro-epibiotic communities of sea turtles have been subject to growing interest in recent years, yet their micro-epibiotic counterparts are almost entirely unknown. Here, we provide the first evidence that diatoms are epibionts for all seven extant species of sea turtle. Using Scanning Electron Microscopy, we inspected superficial carapace or skin samples from a single representative of each turtlespecies. We distinguished 18 diatom taxa from these seven individuals, with each sea turtle species hosting at least two diatom taxa. We recommend that future research is undertaken to confirm whether diatom communities vary between sea turtle species and whether these diatom taxa are facultative or obligate commensals

This study aimed to assess the impact of an entire academic teacher development programme at a Midwestern masters comprehensive university in the United States over a period of five years by examining changes in teaching and student outcomes of nine randomly selected programme participants. Researchers analysed syllabi, course evaluations, grade distributions, programme activity reports, interviews and vita, and concluded that the centre’s impact was greatest on tenure-track faculty who struggled with their teaching. Far more useful to future improvement, however, were the insights gained from reflection on study methods, the researchers’ emotional responses to their findings, their struggle to make sense of the data and grappling with the definition of ‘impact’. In this paper, the researchers share useful lessons learned and illustrate the difficulties inherent in evaluating academic development programmes, with a view to qualifying recommendations currently prevailing in the literature

The Barnes maze has traditionally been used to evaluate visuospatial performance in rats, although the use of genetically modified mice has recently increased. However, few studies have documented the species differences that may affect performance. Here, we report methodological considerations for testing mice on a Barnes maze

Genetic risk for autoimmunity in HLA genes is most often attributed to structural specificity resulting in presentation of self-antigens. Autoimmune vitiligo is strongly associated with the MHC class II region. Here, we fine-map vitiligo MHC class II genetic risk to three SNPs only 47 bp apart, located within a predicted super-enhancer in an intergenic region between HLA-DRB1 and HLA-DQA1, localized by a genomewide association study of 2,853 Caucasian vitiligo patients. The superenhancer corresponds to an expression quantitative trait locus for expression of HLA-DR and HLA-DQ RNA; we observed elevated surface expression of HLA-DR (P = 0.008) and HLA-DQ (P = 0.02) on monocytes from healthy subjects homozygous for the high-risk SNP haplotype. Unexpectedly, pathogen-stimulated peripheral blood mononuclear cells from subjects homozygous for the high-risk super-enhancer haplotype exhibited greater increase in production of IFN-γ and IL-1β than cells from subjects homozygous for the low-risk haplotype. Specifically, production of IFN-γ on stimulation of dectin-1, mannose, and Toll-like receptors with Candida albicans and Staphylococcus epidermidis was 2.5- and 2.9-fold higher in high-risk subjects than in low-risk subjects, respectively (P = 0.007 and P = 0.01). Similarly, production of IL-1β was fivefold higher in high-risk subjects than in low-risk subjects (P = 0.02). Increased production of immunostimulatory cytokines in subjects carrying the high-risk haplotype may act as an u22adjuvantu22 during the presentation of autoantigens, tying together genetic variation in the MHC with the development of autoimmunity. This study demonstrates that for risk of autoimmune vitiligo, expression level of HLA class II molecules is as or more important than antigen specificity

Certain forms of intimate partner violence (IPV) (e.g., psychological aggression, female-perpetrated IPV) may be less likely than others (e.g., male-perpetrated physical aggression) to be considered “abusive.” Research on intimate partner violence (IPV) suggests it is common among young adults, with up to 45-78% experiencing IPV (Linder u26 Collins, 2005; Smith, White, u26 Holland, 2003). Similarly high rates of psychological aggression are reported, with some victims describing it as more harmful than physical IPV (Follingstad et al., 1990). Although IPV is common, data suggest it is not readily identified as abuse in all forms (e.g., female-perpetrated IPV) (Dardis et al., 2015). Undergraduates read two IPV scenarios based the Conflict Tactics Scale (CTS2; Strauss et al., 1996), a widely used measure of IPV. The scenarios depicted increasingly severe (a) physical and (b) psychological acts of IPV. Perpetrator-victim gender in the scenarios was varied across participants, half of whom will receive a brief definition of intimate partner abuse before the scenarios. Participants identified the point in each scenario where they believe the perpetrator’s behavior “crossed the line” and became “abusive.” We predicted that a history of IPV perpetration, maladaptive personality symptoms, accepting attitudes towards IPV, and violence in one’s family of origin would relate to higher thresholds for considering an aggressive act “abusive.” In our sample, a significantly higher proportion of women (33%) as compared to men (10%) reported that they had ever done something physically aggressive to their current or most recent romantic partner (X2 (1, N = 350) = 19.29, p u3c .001). Significant gender differences also were found in the proportion of participants who said that they had been psychologically aggressive toward their partners [55% of men and 68% of women; X2 (1, N = 350) = 5.43, p u3c .05]. Regression analyses predicting participants’ threshold ratings for the IPV scenarios were run separately for male and female participants; socially desirable responding was entered first as a covariate. The models predicting men’s and women’s thresholds for the male-perpetrator physical abuse scenario and those predicting women’s thresholds for the female-perpetrator physical and psychological abuse scenarios were significant. As expected, men with the highest thresholds for “abuse” (i.e., those who only considered severe acts of male physical aggression as abusive) scored high on a measure of narcissistic personality and reported more accepting attitudes toward women’s physical aggression, in particular. Contrary to prediction, men scoring high on a measure of antisocial personality had low thresholds for men’s physical “abuse.” Like men, women with accepting attitudes toward violence had the highest threshold ratings for the male-perpetrator, physical aggression scenarios. With regard to the female-perpetrator scenarios, female participants with the highest thresholds for women’s physical violence had more severe histories of IPV victimization, which was the opposite of our prediction. Women with high thresholds for women’s psychological aggression came from families with high rates of inter-parental violence. There was no difference in the average threshold ratings for participants who did versus did not read an official definition of “abuse” before presentation of the IPV scenarios. However, when participants were asked to rate the severity of each of the eight psychologically- and twelve physically-aggressive acts in the scenarios, differences did emerge, based on exposure to the “abuse” definition. Unexpectedly, women who read the definition tended to rate each aggression item as less severe than women who did not read the definition of abuse. The opposite was true for male participants, who, as expected, tended to rate the abusive acts as more severe, if they were provided the official definition of abuse. 33http://opus.ipfw.edu/stu_symp2016/1010/thumbnail.jp

The definition of system metrics is crucial to determine if a manufacturing system design is truly effective because inappropriate metrics can lead to ineffective or improperly-focused system improvements. This research highlights the importance of measuring the system design that contributes to system effectiveness. The authors propose the use of a Manufacturing System Design Evaluation Tool to assess the effectiveness of the design of manufacturing systems as a whole. The tool was developed based on the Manufacturing System Design Decomposition. The Manufacturing System Design Evaluation Tool measures how well a system is designed based on the requirements outlined in the Manufacturing System Design Decomposition. System effectiveness is evaluated based on six physical manufacturing system configurations: the Departmental or Job Shop Layout, Departments Arranged by Product Flow (sometimes called a Flow Shop), Assembly or Transfer Line, Pseudo-Cell (a cell that is called a cell but does not meet all of the requirements of a cell), individual Assembly or Machining Cells (but not yet integrated as a system), and a Linked-Cell Manufacturing System for all aspects of a production value stream. The Linked-Cell Manufacturing System is considered to be the physical configuration that represents the highest level of manufacturing system design requirements achievement. In addition, the siginificance of implementing one physical element relative to achieving the requirements of the overall manufacturing system design may be evaluated. With this feedback, management is able to identify elements of the system design that need improvement and additional resources. The proposed Manufacturing System Design Evaluation Tool may be applied to evaluate most repetitive, discrete-part manufacturing systems

According to social identity theory, intergroup attitudes are partly determined by the salience of group identification. Group conflict theory proposes that intergroup attitudes are largely determined by perceptions of goal incompatibilities. We integrated these perspectives and predicted that the relationship between ethnic identity and prejudice will be stronger for majority-group members than minority-group members. Our rationale is that identification with a minority group is determined by several factors, while identification with a majority group has fewer determinants, with perceived conflict being one. We therefore also predicted that group identity will mediate the relationship between perceived conflict and prejudice for majority group members, but not for minority group members. To test our predictions, we asked a sample of White Americans (N=101), African Americans (N=98), and Asian Americans (N=66) from a mid-western university to complete a survey. The survey included established measures of ethnic identity, interethnic conflict and ethnic prejudice (presentation counterbalanced). The data were analyzed to test hypothesized conditional indirect effects, moderation effects, and mediated moderation effects. As predicted the results showed that the relationship between ethnic identity and ethnic prejudice was moderated by group status, B = .454, p = .001. Furthermore, as predicted, the relationship was positive for White Americans (B = .382 with African Americans as outgroup, and B = .244 with Asian Americans as outgroup, both p u3c .001), but negative for Asian Americans (B = - .071 African Americans outgroup, and B = - .124 White Americans outgroup, neither significant), and for African Americans (B = -.117 Asian Americans outgroup, and B = - .110 White Americans outgroup, neither significant). We also found that the relationship between perceived conflict and prejudice was significantly mediated by ethnic identity for Whites (B = .022 Asian Americans outgroup, and B = .026 African Americans outgroup), but not for African Americans or Asian Americans, regardless of outgroup. The results support our main propositions that the relationship between group identity and prejudice is moderated by socio-structural variables, and that perceived intergroup conflict and group identity are more strongly associated with each other among majority group members than minority group members. Our findings are discussed in relation to theories of ethnic identity and intergroup relations, and recent studies on the effects of negative interethnic experiences.http://opus.ipfw.edu/stu_symp2016/1014/thumbnail.jp

Tattooing, as one of the oldest practices surviving in contemporary societies, represents the complex nature of globalization. In Japan, where Confucian doctrines strongly reflect many aspects of its culture, the recent global consumerism has created mixed attitudes toward tattooing practices. Due to historical and sociocultural backgrounds, getting tattooed are often associated with criminal activities and rebellion against society. Despite the fact that tattooed people are often stigmatized and frequently conceal their tattoos in contemporary Japan, more tattooists and tattooees overtly present themselves as members of a tattoo culture within that context. Describing a history of Japanese tattooing, Mieko Yamada explains values, beliefs, and practices associated with tattooing during the pre-modern and feudal periods. She also discusses how these have shaped and modified the modern cultural practices and how the latter are being influenced by globalization and postmodern values and practices

Preventive dentistry is a comprehensive approach that should calibrate the entire dental team in the individualized care and education of each patient in the dental practice

Moser Park is a property in Allen County, Indiana, managed by New Haven Parks and Recreation. We conducted a plant survey within the forested section of the park, identifying and quantifying abundance of understory, midstory, and overstory plants. We calculated species richness and Shannonu27s index for all three strata and tested for relationships with environmental variables (i.e., canopy cover, soil compaction, litter depth, and light availability). The majority of understory species are typically associated with disturbed habitats, with very little resemblance to natural, pre-settlement habitat (i.e., low coefficient of conservation values). Understory cover was dominated byRubus allegheniensis. Midstory stratum was less diverse than the understory and was dominated by an abundance of Fraxinus pennsylvanica, which was also an important species in the overstory. The forest at Moser Park matched the Hackberry–American Elm–Green Ash forest type. There was a lack of both Quercus and many Acer species within Moser Park that are common in the region. Because of the distinct soil types, and disturbance history, a relatively uncommon forest type for the region has developed in Moser Park that differs from the majority of forested land surrounding it

Necessary and sufficient conditions for the global solvability of a slow diffusion model with boundary flux governed by memory have been previously shown to be the same as those for a corresponding model with localized nonlinear flux at the boundary. Recent investigations of a similar fast diffusion model with memory have also successfully replicated conditions in parallel with the corresponding localized problem, except for the critical case separating global solvability from blow up in finite time. We provide a suitable modification of an L∞ estimate, typically applied to the case of slow diffusion, which also applies to the fast diffusion model and subsequently establishes global solvability in the critical case. Memory terms appearing in the model are of the type which have been introduced in studies of tumor-induced angiogenesis

Frank Quinn (of Jaffe-Quinn fame, see [1]) worked out the basics of his own account of mathematical practice, an account that is informed by an analysis of contemporary mathematics and its pedagogy (see [2]). Taking this account as our starting point, we can characterize the current mathematical practice to acquire and work with new concepts as a cognitive adaptation strategy that, first, emerged to meet the challenges posed by the growing abstractness of its objects and which, second, proceeds according to the following three-pronged approach: (i) sever as many ties to ordinary language as possible and limit ordinary language explanations to an absolute minimum; (ii) introduce axiomatic definitions and bundle them up with a sufficient num- ber of examples, lemmata, propositions, etc. into small cognitive packages; (iii) practice hard with one new cognitive package at a time. Drawing on research in cognitive science, and especially in mathematics ed- ucation, I will then show how cognitive science provides supporting evidence for the effectiveness of this mathematical practice. Time permitting, I will then complement these findings from a phenomenological perspective by exhibiting a fruitful convergence between mathematics, cognitive science, and phenomeno- logical analysis.
