Factors Predicting Among Nursing Students Seek Factors Predicting Intention Among Nursing Students to Seek Professional Psychological Help

: Nursing students are a high risk group for mental health problems; however they rarely seek professional psychological help. The purpose of this descriptive, cross-sectional study was to examine factors predicting nursing students’ intention to seek professional psychological help by using the Ajzen’s theory of planned behavior as a framework. The participants were 343 students from a faculty of nursing in Thailand who were screened for psychological distress. Participants were asked to complete self-reported questionnaires, including a demographic data questionnaire, the Depression Anxiety Stress Scale, and the Professional Psychological Help-Seeking Questionnaire. Data were analyzed using descriptive statistics and multiple regression. The findings showed that three independent variables, attitudes toward behavior, subjective norm, and perceived behavioral control that accounted for 16.3 % of variance in the participants’ intention to seek professional help. Attitudes toward behavior and subjective norm can significantly predict the intention to seek professional psychological help, but the other did not. In addition, behavioral beliefs, normative beliefs, and control beliefs could predict attitudes toward behaviors, subjective norm, and perceived behavioral control, respectively. The findings underscore the importance of working closely with counseling services and the professions in order to ensure nursing students’ access to needed support, to increase positive attitudes toward the help-seeking behavior of nursing students and their significant groups, and create cultures of seeking such help across nursing campuses.

Stimulation of Tubulin Dimer Assembly by Chlamydomonas FlageUar Extracts

Although much information is available concerning the structure and function of cilia and flagella (26), little is known about the assembly of these organelles and in particular about the control of their assembly. Available experimental evidence suggests that some component or components released into the cytoplasm by resorbing cilia and flagella limit the subsequent regeneration of these structures in the absence of protein synthesis (5, 22, 23). Williams (33) has suggested that in Tetrahymena there exists a high molecular weight axonemal protein that regulates ciliary assembly. Protein factors that control both the initiation and extent of assembly of brain tubulin dimers in vitro have been found in preparations of mammalian and avian brain microtubule protein obtained by cycles of in vitro polymerization (12, 14, 20, 32, footnote 1). These observations prompted a search for similar regulatory factors within the flagellar axoneme.
Molecular characterization of isolates of Alternariaster helianthi causing sunflower blight

: The genetic variability of 25 isolates of Alternaria helianthi was assessed using thirty Inter Simple Sequence Repeat (ISSR) primers. The Jaccard similarity coefficient values among A. helianthi isolates ranged from 0.22 to 1.00. The higher similarity co-efficient value of 1.00 was observed between the isolates Ah-2 and Ah-13 whereas, the least similarity co-efficient was observed between isolates Ah-10 and Ah-11 as well Ah-10 and Ah-15. At 65% similarity level, cluster analysis of similarity index data classified 25 isolates into 7 groups and the classification was presented as a dendrogram. Among the 7 groups, group-I was largest consisting of 15 isolates and was again divided into four subgroups. The isolates Ah-2 and Ah-13 showed 100 per cent genetic similarity though they were collected from two different states. The isolates Ah-5, Ah-6, Ah-10 and Ah-12 were distinctly different from other isolates forming three separate groups. Thus the present study revealed genetic relatedness between different isolates of A. helianthi . It was also found that, there was no evidence for geographical clustering of isolates with high levels of genetic similarity suggesting that the isolates are widely spread across the locations.
Integrated Technologies for Communication Security and Secure Deletion on Android Smartphones

— Nowadays, mobile devices are powerful enough to accomplish most of the tasks previously accomplished only by personal computers; that includes, for example, file management and instant messaging. On the other hand, in order to protect final user’s interests, there is also an increasing need for security hardenings on ordinary, off-the-shelf devices. In fact, there is a need for practical security technologies that work at the application level, above the operating system and under the control of the user. This technology has to be easy to use in everyday activities and easily integrated into mobile devices with minimal maintenance and installation costs. The main contribution of this paper is to describe design and implementation issues concerning the construction of an integrated framework for securing both communication and storage of sensitive information of Android smartphones. Four aspects of the framework are detailed in this paper: the construction of a cryptographic library, its use in the development of a cryptographically secure instant message service, the integration with an encrypted file system, and the addition of secure deletion technologies. Also, an analysis of non-standard cryptography is provided, as well as performance evaluation of a novel secure deletion technique. The proposed framework is supposed to work in user-mode, as an ordinary group of mobile apps, without root access, with no need for operating system modification, in everyday devices.
Reviewing adaptive management through a wicked lens

Regional scale adaptive management has become part of the rhetorical landscape of natural resource/environmental management. It is now unremarkable, even expected, that strategies programs and plans contain a section detailing how implementation will fit within an adaptive management framework (for a recent example, see State Water Corporation 2007). Adaptive management has become attractive because acknowledgement and acceptance of complexity and uncertainty in environmental management has prompted questioning of conventional natural resource planning (Lachappelle, McCool et al. 2003). This questioning of conventional planning and management has taken on an urgent air as many environmental/ natural resource management problems, including water management (Freeman 2000) and ecological sustainability (Durant and Legge 2006), are apparently becoming so complex and unknowable they are called 'wicked'. In this chapter I discuss 'wicked' problems, and suggest that understanding managers' responses to them can illuminate aspects of adaptive management as it is practiced. To illustrate my nascent proposal I revisit my empirical study of the CSIRO/Murray-“Darling Basin Commission Heartlands initiative which operated in NSW and Victoria between 2000 and 2003 URLs: http://www.publish. csiro.au/pid/6002.htm http://researchoutput.csu.edu.au/R/-? func=dbinjump-full&object_id=12966&local_base=GEN01-CSU01 Author Address: callan@csu.edu.au CRO Identification Number: 12966 Reviewing adaptive management through a wicked lens Catherine Allan Senior Lecturer, Environmental Sociology and Planning Institute for Land Water and Society, Charles Sturt University, Albury, NSW, Australia Simplex, complex and multiplex.

Resilient Monotone Submodular Maximization

—In this paper, we focus on applications in machine learning, optimization, and control that call for the resilient selection of a few elements, e.g. features, sensors, or leaders, against a number of adversarial denial-of-service attacks or failures. In general, such resilient optimization problems are hard and cannot be solved exactly in polynomial time, even though they may involve objective functions that are monotone and submodular. In this paper, we provide for the solution of such optimization problems the ﬁrst scalable approximation algorithm that is valid for any number of attacks or failures and which, for functions with low curvature, guarantees su- perior approximation performance. Notably, the curvature has been known to tighten approximations for several non-resilient optimization problems, yet its effect on resilient optimization had hitherto been unknown. We complement our theoretical analyses with empirical evaluations.
Evolution of dopamine receptors: phylogenetic evidence suggests a later origin of the DRD[sub]2l[sub] and DRD[sub]4rs[sub] dopamine receptor gene lineages

Dopamine receptors are integral membrane proteins whose endogenous ligand is dopamine. They play a fundamental role in the central nervous system and dysfunction of dopaminergic neurotransmission is responsible for the generation of a variety of neuropsychiatric disorders. From an evolutionary standpoint, phylogenetic relationships among the DRD1 class of dopamine receptors are still a matter of debate as in the literature different tree topologies have been proposed. In contrast, phylogenetic relationships among the DRD2 group of receptors are well understood. Understanding the time of origin of the different dopamine receptors is also an issue that needs further study, especially for the genes that have restricted phyletic distributions (e.g. DRD2l and DRD4rs). Thus, the goal of this study was to investigate the evolution of dopamine receptors, with emphasis on shedding light on the phylogenetic relationships among the D1 class of dopamine receptors and the time of origin of the DRD2l and DRD4rs gene lineages. Our results recovered the monophyly of the two groups of dopamine receptors. Within the DRD1 group the monophyly of each paralog was recovered with strong support, and phylogenetic relationships among them were well resolved. Within the DRD1 class of dopamine receptors we recovered the sister group relationship between the DRD1C and DRD1E, and this clade was recovered sister to a cyclostome sequence. The DRD1 clade was recovered sister to the aforementioned clade, and the group containing DRD5 receptors was sister to all other DRD1 paralogs. In agreement with the literature, among the DRD2 class of receptors, DRD2 was recovered sister to DRD3, whereas DRD4 was sister to the DRD2/DRD3 clade. According to our phylogenetic tree, the DRD2l and DRD4rs gene lineages would have originated in the ancestor of gnathostomes between 615 and 473 mya. Conservation of sequences required for dopaminergic neurotransmission and small changes in regulatory regions suggest a functional refinement of the dopaminergic pathways along evolution.
Research A Structural Equation Modeling (SEM) Approach to Explore the Association between Corporate Social Responsibility and Financial Performance: A Single Mediating Mechanism

Abstrac t : The past couple of decades have seen a growing interest in Corporate Social Responsibility (CSR) research in both business and academia. It has been observed that a substantial number of studies on CSR and Financial Performance (FINP) have focused almost entirely on large firms. As pointed out earlier, the bulk number of studies on the link between CSR-firm performances is from developed countries. Thus, a limited number of studies have been conducted in developing countries and more especially in Bangladesh. We cannot generalize the findings from developed countries to developing countries without further research, therefore, requiring more research on the association between CSR and firm performance in manufacturing companies. Objective: This paper aims to exploring how CSR dimensions influence the financial performance and whether the mediating effect of selected organizational factors determine the relationship between CSR and financial performance. Methods: A self-administered questionnaire was used along with the simple random sampling method to collect 371 respondents’ views from medium and small scale manufacturing firms in Bangladesh. The results were analyzed by using SEM. Confirmatory Factor Analysis (CFA) was performed followed by structural model to examine the proposed model. Findings: The findings demonstrated that CSR representative of the wider population. Thus the findings of this study cannot be generalized to other industrial sectors in Bangladesh. However, future research could be carried out on large samples.

A COMPARATIVE STUDY OF CONTACT STRESS FROM DIFFERENT STANDARDS FOR SOME THEORETICAL STRAIGHT BEVEL GEAR PAIRS

ANSI/AGMA 2003-B97, ISO 10300 standards and a new contact stress model are used to estimate and compare contact stresses in some theoretical straight bevel gear pairs. The contact stress expressions in the different gear standards and new model are formatted to highlight the similarity and differences. The power range of 10 to 15,000 kW, backend modules of 2.5 to 25 mm and backend pitch velocities of 4.58 to 25.37 m/s are covered. The results indicate that the percentage differences between the new contact stress and AGMA models are in the range of 2.22% to 7.40%. These differences are small but can mean significant improvement in the pitting life expectancy of the gears since life and contact stress is related by a power law of approximately 9th degree. For example, a 5% decrease in contact stress could mean a pitting life increase of about 50%. The percentage differences between the new and ISO 10300 models contact stresses are in the range of -6.57% to 67.34%. These are large differences, indicating that much shorter pitting life should be expected based on the ISO model. The differences from The ISO 10300 standards may be attributed to the use of the mid facewidth cone radius in its contact stress model while the new model and AGMA standards use the backend cone radius which is larger than the mid facewidth cone radius. Another contributing factor to the differences is that the load service factor values evaluated from ISO methods are generally higher than those of the new model values which are based largely on AGMA methods. Since the ANSI/AGMA standards yield results that are considered to be conservative and the new contact stress model gives values that are marginally lower than the AGMA predictions, the new contact stress model deserves some serious considerations.
EffectsCells: Expression and Proinflammatory CD40 on Adult Human Airway Epithelial

CD40/CD40 ligand interaction is an important pathway for B and T cell cooperation and function; functional CD40 molecules have recently been found on nonhematopoietic cells. We detected CD40 in vivo on normal human respiratory epithelial cells and showed that its expression is increased on inﬂamed airway epithelium. Subsequently, we analyzed its expression and function on primary cultures of human airway epithelial cells. Our data show that CD40 is up-regulated by IFN- (cid:1) and IFN- (cid:2) , its ligation increases the surface expression of CD54 and CD106 and it may stimulate the release of IL-6 and IL-8. The use of Janus kinase 3 (JAK3) and NF- (cid:3) B inhibitors suggests that both basal and CD40-induced release of the two cytokines is JAK3-dependent. Using colocalization techniques, we revealed the existence of CD40/JAK3 and CD40/TNFR-associated factor 2 interplay. The extent of these interactions may be partial (2–40% of the cells) or massive (80–90% of the cells) in cultured cells. Stimulation via CD40 causes a signiﬁcant increase in the number of cells expressing colocalization only in the cultures displaying low frequency of initial colocalization. Thus, airway epithelial cells, activated by CD40, may behave as effector cells of the inﬂammation process and should be considered priority targets for anti-inﬂammatory therapy. This work identiﬁes CD40 and the correlated JAK3 signaling molecule as potential molecular targets to block the inﬂammatory functions of epithelial cells.

UNIVERSITY OF CALIFORNIA Los Angeles Sensory Ecology of Ithomiine Butterflies: signal quality, strategy and relative importance (Ithomiini spp.) A dissertation submitted in partial satisfaction of the Requirements for the degree Doctor of Philosophy in Biology by Adrea Gonzalez-Karlsson

Multimodal communication in mimetic species enables convergence within individual sensory modalities. Because ithomiine butterflies form multispecies aggregations with many individuals of multiple species, they are an interesting test case within which to examine modality use in conspecific discrimination. We found that social interactions within natural ithomiine aggregations are largely intraspecies interactions between males and females. Using two-way choice tests, we showed that ithomiines are more strongly attracted to the pheromones of their own species than to the pheromones of other ithomiine species. Using artificial models of butterflies, we found that ithomiines preferentially approach models of their own versus other mimetic color patterns. In other lepidopterans, reliance on visual and chemical cues is equal. However, visually mimetic butterflies are hypothesized to rely more heavily on chemical than visual cues. To test this, we performed four-way choice tests with mimetic and non-mimetic pairs of ithomiine species, Greta morgane (clear), Ithomia patilla (clear) and I. heraldica (amber). The butterflies chose between pairs of cues; either conspecific or heterospecific wing patterns paired with conspecific or heterospecific hairpencils (pheromone distributing organ). We found that the mimetic species G. morgane (clear) and I.patilla (clear) rely more heavily on chemical cues than on visual cues for discriminating conspecifics from heterospecifics while the non-mimetic species G. morgane (clear) and I. heraldica (amber) rely to the same degree on chemical and visual cues. This is the first experimental evidence that visual mimicry is associated with reliance on chemical cues in butterflies.
On the Norm of a Composition Operator

Let φ be an analytic map that takes the open unit disk of C into itself. The composition operator Cφ, acting on either the Hardy space H 2 or one of the weighted Bergman spaces Aα, is defined by the rule Cφ(f) = f ◦ φ. Every composition operator is bounded on each of these spaces, but the exact value of its norm is rarely known. In view of this situation, we consider several problems relating to this basic, yet elusive question. Our strategy for studying ‖Cφ‖ centers around determining the spectrum of the operator C∗ φCφ. We obtain our most substantial results in the context of H, in particular for a composition operator induced by a linear fractional map: • We determine the conditions under which ‖Cφ‖ is given by the action of either Cφ or C ∗ φ on the reproducing kernel functions of H . • Assuming a specific set of conditions on φ, we describe ‖Cφ‖ in terms of the zeros of a particular polynomial. • We obtain several results, in the case where φ(0) = 0, pertaining to the norm of Cφ acting on various subspaces of H .
Evaluation of the growth sustaining attributes of Rhizophora mucronata Lam. for strategic afforestation protocols

Afforestation program on mangroves primarily require reliable information on the growth requirements of the targeted mangrove species. The present investigation was carried out to evaluate the hydrogeochemical, sedimentological and climatological conditions ideal for the growth and establishment of the mangrove species Rhizophora mucronata Lam. in pursuit of their afforestation practices. Estimation of the physicochemical characteristics of water and soil / sediment along with climatological attributes from three heterogeneous habitats falling in the coastal environments of Kerala was monitored monthly for a period of one year for deriving conclusions regarding the growth requirements of R. mucronata Lam. Statistical analysis revealed the most vital attributes of water which influence the growth of R. mucronata are water pH, TSS, resistivity, alkalinity and potassium and also in sedimentological characteristics such as silt %, organic carbon, nitrogen, potassium and sodium without any significant variation. The study as a whole reported the capability of R. mucronata to cope up with different hydrological and sedimentological conditions in terms of tolerance or augmented range, which will form a basis for future afforestation initiatives.
