Influence of phosphorus loading on organic nitrogen mineralization of Everglades soils

There have been recent concerns about the anthropogenic phosphorus (P) loading to the naturally oligotrophic Everglades ecosystem. We investigated the effect of P loading on the biogeochemical cycling of nitrogen (N). We investigated the distribution of the potentially mineralizable N (PMN) rate as an indicator of the influence of P loading on selected microbial activities in soil and detritus layers. Soil characteristics measured included bulk density; total C, N, and P; microbial biomass C; and N and extractable NH 4 + . PMN rates ranged from 10.4 to 325 mg N kg -1 d -1 . The highest values of microbial biomass C and N, total P, extractable NH 4 + , and PMN were observed in the detrital layer, and rates decreased with increasing soil depth. An increase in the size of the microbial pool and heterotrophic activity (organic N mineralization) was found to be related to the P-loading rate and related to the distribution of total P content in the soil and detrital layers. Extractable NH 4 + was a good indicator of PMN rates and total P was found to be significantly correlated to microbial biomass C and N. The stimulatory effect of P enrichment on microbial activity, overall size of the microbial biomass pool, and the PMN rate has led to an increased availability of inorganic N, which could potentially affect macrophyte growth and water quality of the northern Everglades system.
The Impact of Fake Reviews on Online Visibility: A Vulnerability Assessment of the Hotel Industry

Extant research has focused on the detection of fake reviews on online review platforms, motivated by the well-documented impact of customer reviews on the users’ purchase decisions. The problem is typically approached from the perspective of protecting the credibility of review platforms, as well as the reputation and revenue of the reviewed firms. However, there is little examination of the vulnerability of individual businesses to fake review attacks. This study focuses on formalizing the visibility of a business to the customer base and on evaluating its vulnerability to fake review attacks. We operationalize visibility as a function of the features that a business can cover and its position in the platform’s review-based ranking. Using data from over 2.3 million reviews of 4,709 hotels from 17 cities, we study how visibility can be impacted by different attack strategies. We find that even limited injections of fake reviews can have a significant effect and explore the factors that contribute to this.
Valid Statistical Inference Based on Feedforward Artificial Neural Network Models

With the help of recent theoretical results, we use the estimates from neural network modelling as basis for formal statistical inference. Multilayer perceptrons are applied to model biomass in a complex alpine terrain with limited amount of variables by combining temporal remote sensing with classical field methods from plant physiology. We test the hypothesis that the dynamics of the biomass distribution can be captured with the help of geo-registered and ortho-rectified colour images from the opposing hill slope. Therefore the network model is trained carefully and misspecification is tested by the non-linearity tests of Ramsey and of Teräsvirta, Lin and Granger. Plausibility and sensitivity analysis as well as ecological considerations in respect of content support the validity of our final model. With the help of bootstrap techniques the significance of colour patterns for modelling phytomass is demonstrated.
Stability of a slowly diverging axisymmetric jet in the presence of a coflow

The stability theory has been a successful method for the understanding of supersonic jet-noise generation [8]. However, in the case of subsonic jets, noise mechanisms are still debated. Hence, the acoustical emission by vortex pairing [2] conflicts with the theory of superdirectivity [5] [4]. In this model, the acoustical source is supposed to result of an instability of global mode type [4] [3] .
Nutritional quality evaluation of Rice bean flour based Papad

Efficacy of different wooden blocks as dispenser block of methyl eugenol (Male Annihilation Technique) for attraction of Bactrocera species has been studies. Self-made transparent rectangular PET plastic jars around 1 litter capacity and having four circular holes of 1 cm in diameter on four sides of the jar just below the shoulder of the bottle (i.e. 1/ 3rd from top) openings for the entry of flies. The pooled data of mean weekly catch was recorded highest in plywood dispenser block (13.40 flies/trap/week) followed by mango (13.37 flies/trap/week) and neem (12.67 flies/trap/week) and lowest in babul dispenser block (10.97 flies/trap/week) followed by sissoo (11.28 flies/trap/week) in 7th DAI. The mean persistence period was highest in plywood dispenser block, while lowest in sissoo dispenser block When overall mean values of trap-catch were considered from DAI, highest efficacy was noted by plywood (7.61 flies/trap/week) followed by mango (7.48 flies/trap/week) and neem dispenser block (7.29 flies/trap/week) whereas lowest catch was observed in sissoo (5.67 flies/trap/week) followed by babul dispenser bock (6.06 flies/trap/week). The results also suggested that more number of flies’ species were annihilated in second year of experimentation than first year.
Lipid Raft- and Protein Kinase C-mediated Synergism between Glucocorticoid- and Gonadotropin-releasing Hormone Signaling Results in Decreased Cell Proliferation*

Background: The glucocorticoid receptor cross-talks with other receptors to integrate cell signaling. Results: Glucocorticoids and GnRH synergistically up-regulate select mRNA levels via protein kinase C and flotillin-1 to repress cell proliferation. Conclusion: Cross-talk between membrane-associated receptors modulates protein kinase C-dependent synergistic and gene-specific transcription by intracellular glucocorticoid receptor. Significance: Glucocorticoid and GnRH receptor cross-talk integrates adrenal and gonadal signaling to fine-tune cell proliferation. Cross-talk between the glucocorticoid receptor (GR) and other receptors is emerging as a mechanism for fine-tuning cellular responses. We have previously shown that gonadotropin-releasing hormone (GnRH) ligand-independently activates the GR and synergistically modulates glucocorticoid-induced transcription of an endogenous gene in LβT2 pituitary gonadotrope precursor cells. Here, we investigated GR and GnRH receptor (GnRHR) cross-talk that involves co-localization with lipid rafts in LβT2 cells. We report that the GnRHR and a small population of the GR co-localize with the lipid raft protein flotillin-1 (Flot-1) at the plasma membrane and that the GR is present in a complex with Flot-1, independent of the presence of ligands. We found that the SGK-1 gene is up-regulated by Dex and GnRH alone, whereas a combination of both ligands resulted in a synergistic increase in SGK-1 mRNA levels. Using siRNA-mediated knockdown and antagonist strategies, we show that the gene-specific synergistic transcriptional response requires the GR, GnRHR, and Flot-1 as well as the protein kinase C pathway. Interestingly, although several GR cofactors are differentially recruited to the SGK-1 promoter in the presence of Dex and GnRH, GR levels remain unchanged compared with Dex treatment alone, suggesting that lipid raft association of the GR has a role in enhancing its transcriptional output in the nucleus. Finally, we show that Dex plus GnRH synergistically inhibit cell proliferation in a manner dependent on SGK-1 and Flot-1. Collectively the results support a mechanism whereby GR and GnRHR cross-talk within Flot-1-containing lipid rafts modulates cell proliferation via PKC activation and SGK-1 up-regulation.
Managers ' Implicit Theories of Motivation : How Managers Think Motivation " Works "

McGregor (1960) asserted that the study of motivation in organizational settings must include managers’ beliefs about motivation, but this has rarely been examined. Semi-structured interviews of practicing managers explicated six common general implicit theories of motivation. Using a forced choice questionnaire and Thurstone scaling, managers’ endorsement of the theories was assessed. Relational demographic variables such as manager’s age and the interaction of manager’s age with the average age of subordinates – but not managerial race, gender, or tenure – helped explain managerial endorsement of implicit theories. Between-organization differences were also found, suggesting that organizational climate and culture could be related to endorsement of implicit theories of motivation.
Pimaradienoic Acid Inhibits Carrageenan-Induced Inflammatory Leukocyte Recruitment and Edema in Mice: Inhibition of Oxidative Stress, Nitric Oxide and Cytokine Production

Pimaradienoic acid (PA; ent-pimara-8(14),15-dien-19-oic acid) is a pimarane diterpene found in plants such as Vigueira arenaria Baker (Asteraceae) in the Brazilian savannas. Although there is evidence on the analgesic and in vitro inhibition of inflammatory signaling pathways, and paw edema by PA, its anti-inflammatory effect deserves further investigation. Thus, the objective of present study was to investigate the anti-inflammatory effect of PA in carrageenan-induced peritoneal and paw inflammation in mice. Firstly, we assessed the effect of PA in carrageenan-induced leukocyte recruitment in the peritoneal cavity and paw edema and myeloperoxidase activity. Next, we investigated the mechanisms involved in the anti-inflammatory effect of PA. The effect of PA on carrageenan-induced oxidative stress in the paw skin and peritoneal cavity was assessed. We also tested the effect of PA on nitric oxide, superoxide anion, and inflammatory cytokine production in the peritoneal cavity. PA inhibited carrageenan-induced recruitment of total leukocytes and neutrophils to the peritoneal cavity in a dose-dependent manner. PA also inhibited carrageenan-induced paw edema and myeloperoxidase activity in the paw skin. The anti-inflammatory mechanism of PA depended on maintaining paw skin antioxidant activity as observed by the levels of reduced glutathione, ability to scavenge the ABTS cation and reduce iron as well as by the inhibition of superoxide anion and nitric oxide production in the peritoneal cavity. Furthermore, PA inhibited carrageenan-induced peritoneal production of inflammatory cytokines TNF-α and IL-1β. PA presents prominent anti-inflammatory effect in carrageenan-induced inflammation by reducing oxidative stress, nitric oxide, and cytokine production. Therefore, it seems to be a promising anti-inflammatory molecule that merits further investigation.
Cultural Influences on Intercultural Relationships for Women

Women are an active group of sojourners to travel to different cultures for various reasons, and marriage is one of them. Women’s experience in intercultural relationships may be connected with their backgrounds, values and other factors related to their ethnicity. This case study investigates three women from various backgrounds and explores their perspectives and experiences in their intercultural relationships. The purpose of this paper is to contribute to the knowledge base of women’s intercultural life and to illuminate the importance of intercultural communication in intimate relationships.
Trypanosoma cruzi: Adhesion to the Host Cell and Intracellular Survival

Both invasion of the host cell by T. cruzi and its establishment into the mammalian host are critical steps. In this review, the adhesion step and the intracellular survival in non‐professional phagocytes are particularly focused on, with special emphasis on the role of Gp85/trans‐sialidase (Gp85/TS) superfamily. Excellent reviews have been published lately, some covering other aspects of T. cruzi ‐ host interaction and will be cited instead of the original articles due to limited number of listed references.

Employee Turnover in the Hospitality Industry using Herzberg’s Two-Factor Motivation-Hygiene Theory

The purpose of this correlational study, grounded in the motivation-hygiene theory, was to assess the relationship between employee turnover intention and job satisfaction, employee compensation, employee engagement, employee motivation, and work environment. A convenience sample of 156 hospitality employee from Western Georgia; Central Mississippi; and North Central Texas completed an online survey. Simultaneous multiple linear regression was the statistical technique used to analyze this data. In the final model, the 5 predictors accounted for approximately 36% of the variance in turnover intention, and the result was statistically significant, (R2 =. 36, F (5, 105) = 11.57, p
Diversity and genetic structure in natural populations of Hancornia speciosa var. speciosa Gomes in northeastern Brazil

Hancornia speciosa Gomes is a fruit tree native from Brazil that belongs to Apocinaceae family, and is popularly known as Mangabeira. Its fruits are widely consumed raw or processed as fruit jam, juices and ice creams, which have made it a target of intense exploitation. The extractive activities and intense human activity on the environment of natural occurrence of H. speciosa has caused genetic erosion in the species and little is known about the ecology or genetic structure of natural populations. The objective of this research was the evaluation of the genetic diversity and genetic structure of H. speciosa var. speciosa. The genetic variability was assessed using 11 allozyme loci with a sample of 164 individuals distributed in six natural populations located in the States of Pernambuco and Alagoas, Northeastern Brazil. The results showed a high level of genetic diversity within the species (e= 0.36) seeing that the most of the genetic variability of H. speciosa var. speciosa is within its natural populations with low difference among populations ( = 0.081). The inbreeding values within ( = -0.555) and among populations ( =-0.428) were low showing lacking of endogamy and a surplus of heterozygotes. The estimated gene flow ( m ) was high, ranging from 2.20 to 13.18, indicating to be enough to prevent the effects of genetic drift and genetic differentiation among populations. The multivariate analyses indicated that there is a relationship between genetic and geographical distances, which was confirmed by a spatial pattern analysis using Mantel test (r = 0.3598; p = 0.0920) with 1000 random permutations. The high genetic diversity index in these populations indicates potential for in situ genetic conservation.
Impact of intensive venous sampling on characterization of pulsatile GH release.

The effect of sampling intensity on quantitative properties of pulsatile growth hormone (GH) release was tested using an objective, statistically based pulse detection algorithm (Cluster). Seven normal young men had blood withdrawn at 5-min intervals for 24 h. The number of GH peaks/24 h (mean +/- SE) detected in the 5-min series (5.93 +/- 0.66) was significantly greater than the number of peaks documented in the constituent 10-min (3.45 +/- 0.28), 15-min (2.79 +/- 0.31), 20-min (2.86 +/- 0.64), 30-min (2.5 +/- 0.36), 45-min (2.21 +/- 0.21), and 60-min (1.93 +/- 0.23) series. The increased number of peaks detected with 5-min sampling reflected high-frequency pulsatile GH release occurring within the major GH secretory episodes. Both the mean widths and areas associated with peaks identified in the 5-min series were smaller than those documented with less intensive sampling. Peak amplitude did not change with sampling intensity. These data suggest that the major secretory episodes of GH release in normal young men encompass high-frequency GH secretory activity. That these high-frequency GH secretory events have not previously been described probably reflects the relatively infrequent sampling paradigms (e.g., every 20-30 min) commonly used in the past.
Corrigendum to “ Well-posedness of some initial-boundary-value problems for dynamo-generated poloidal magnetic fields ” [ PRSE , 139 A , 1209-1235 , 2009 ]

In Theorem 3.3 of [1] we gave an incomplete characterization of the spaces Dk/2 associated with the operators Ak/2, k ∈ N, and, as a consequence, we missed compatibility conditions in the subsequent Theorem 4.5 and Corollary 4.6. In this erratum we give corrected versions of these results. We start with an additional lemma which improves the regularity result (2.9b) in [1] and provides an estimate needed in the subsequent theorem.
EFFICACY OF PAROXETINE AND MIRTAZAPINE ON SLEEP IN PATIENTS WITH DEPRESSION AND THEIR RELATIONSHIP WITH POLYSOMNOGRAPHY

This study aimed to investigate the effect of paroxetine and mirtazapine on polysomnography (PSG) and sleep quality in patients with depression, and to explore the changes in PSG scores after the antidepressant treatment. Patients were divided into two groups: paroxetine group (P group) and mirtazapine group (M group). The PSG scores and sleep quality were compared before and six weeks after the antidepressant treatment. The severity of depression was assessed by the Hamilton Rating Scale for Depression (HAMD). Patients sleep quality was assessed by HAMD sleep disorder score and Pittsburgh Sleep Quality Index (PSQI). The efficacy of the antidepressant treatment was assessed by HAMD score reduction percentage. Abnormalities during sleep, sleep structure and rapid eye movement (REM) sleep indicators were observed in the depressed patients compared to the control group. The effect of antidepressant medication in P group included: the number of awakening and sleepiness increased, the sleep efficiency decreased, the preponderance of Stage1 (S1) increased, REM sleep time and percentage decreased, REM sleep latency and REM activity and intensity decreased (p < 0.05). Assessment of depression medication in M group showed: the sleep latency shortened; the number of awakening and sleepiness episodes decreased; the sleep efficiency increased; and the percentage of S1 decreased. In this group, the REM sleep was not statistically significantly changed. The scores of HAMD and PSQI in P group and M group were statistically significantly lower than those before the antidepressant treatment (p < 0.05). There were no statistically significant differences in HAMD and PSQI scores between group P and M after the treatment of depression (p > 0.05). HAMD reduction percentage and PSG score were not statistically significant correlated (p > 0.05). At the end of the trial, patients with HAMD scores reduced by 50% were labelled as responders; those with less than 50% were labelled as non-responders. The Delta sleep in the non-responders group was statistically lower compared to the responders group.
Ethnobotanical Survey of Commonly Used Medicinal Plants in Northern Cross River State, Nigeria

An ethnobotanical survey of commonly used medicinal plants was carried out among the people of Northern Cross River comprising five Local Government Areas (Ogoja, Yala, Bekwarra, Obudu and Obanliku) in Cross River State, Nigeria through the use of oral interview using short structured questionnaires. Those interviewed included herbalist (native doctors) and herbal medicine sellers. The survey was to identify commonly used medicinal plants in these areas and how these medicinal plants are sourced and used. Results obtained from the survey show that a total of 110 plant species belonging to 43 families were identified as commonly used medicinal plants in the study area. The commonly used medicinal plants are mostly sourced from uncultivated land, communal (unprotected) and protected forests and farm lands. The survey revealed some of the local uses of these plants and the different ailments they can cure.
Does experience help or hinder top managers? Working with different types of resources in Hollywood

Research summary: Research on the resource-based view has begun to place more emphasis on the ability of managers to extract better performance from the resources that are available to them. In this paper, we show that prior experience can both help and hinder their ability to generate performance from various categories of resources. Further, we argue that the fungibility of each resource influences the opportunities managers have to use their experiences in order to find the best method to deploy them. We test our hypotheses by examining the ability of Hollywood film producers to generate results from financial, brand, and human resources. Our findings show that experienced producers can generate better performance from more fungible resources, but they actually achieve weaker results with less fungible resources. Managerial summary: Do more experienced top managers get better results from their resources? We examine this question for Hollywood film producers. Our results show that experience can really help when producers work with resources such as cash (budgets) and brand resources (such as film sequels). However, such experiences actually reduce performance when they work with some human resources, such as highly talented directors. We argue that experience can be most helpful when managers work with more fungible resources, which can be used in a variety of different ways but can actually hurt when they work with resources that are more constrained in how they can be deployed. Under ideal circumstances, we find that experienced producers can generate nearly 40 percent more revenue with the right mix of resources. Copyright © 2015 John Wiley & Sons, Ltd.
Protection against murine cytomegalovirus retinitis by adoptive transfer of virus-specific CD8+ T cells.

PURPOSE Human cytomegalovirus retinitis, the most common ophthalmic infection of AIDS patients, has been modeled in BALB/c mice infected with murine cytomegalovirus by the supraciliary route. A series of depletion and adoptive transfer studies was performed to determine whether adoptive transfer of T cells protects mice from retinitis caused by murine cytomegalovirus infection after supraciliary inoculation and to determine which subset of T cells is responsible for protection. METHODS BALB/c mice were thymectomized and T cell-depleted by injection of monoclonal antibodies to CD4, CD8, or both. Murine cytomegalovirus (9 x 10(2) plaque forming units [pfu]) was injected into the supraciliary space. Experimental animals received murine cytomegalovirus-specific T cells or subsets of T cells 2 hours before virus injection, whereas control animals received herpes simplex virus type 1-specific T cells by tail vein injection. Eight days after virus injection, retinal pathology was scored by histopathologic examination of hematoxylin and eosin-stained ocular sections. RESULTS CD8+ T cell depletion was sufficient for development of retinitis after supraciliary injection of murine cytomegalovirus. Adoptive transfer of murine cytomegalovirus-specific T cells, but not herpes simplex virus type 1-specific T cells, provided protection from retinitis. Additionally, separation of the murine cytomegalovirus-specific T cells into CD8+ and CD4+ subsets before adoptive transfer showed that the CD8+ fraction of the adoptive T cells was responsible for protection. CONCLUSIONS These results suggest that adoptive transfer of cytomegalovirus-specific T cells or T cell subsets might be used to treat or prevent cytomegalovirus retinitis in immunosuppressed human patients.
