Two nurse teachers reflect on acquiring their nursing identity

As nurse teachers, researchers and practitioners, we live within a changing landscape of the nursing profession. There is a continuous search for a clear definition of what nursing is and what role it plays on the social and political stage. We believe that one way to approach the task of delineating our professional identity as nurses is through individual self‐reflection on, and sharing of, our personal and professional narratives. We suggest that this exploration may be attained through the reflective process of narrative inquiry, which is at once the method and the phenomenon of study. Further, Connelly and Clandinin build on Dewey’s work on experience, and postulate that we bring all of our personal life experiences into our professional life. Consequently, by examining what personal experiences each of us brings into the profession we learn about who we are professionally. By knowing who we are professionally as individual nurses we have the potential to become clearer on what nursing is and what it does. Similarly, by striving to understand our individual professional identity we as nurses contribute to the creation of the nursing profession as a whole. Therefore, through the telling and retelling of these life experiences we may gain deeper understanding of who we are as individual nurses within the context of the nursing profession.
Corporate Social Responsibility and Chinese Oil Multinationals in the Oil and Gas Industry of Nigeria: An appraisal

This article focuses on the extant corporate social responsibility (CSR) practices in the oil and gas industry in Nigeria. The oil and gas sector of Nigeria has been beset by a lot of problems not limited to violence, kidnappings, eco-terrorism, and maladministration amongst others. One way of curing the inherent problems is the use of CSR by many oil multinational corporations (MNCs) operating in Nigeria. This article focuses on the Chinese oil firms operating in the oil and gas industry in Nigeria and investigates if they operate on the same basis as the Western firms. It seeks to determine whether the variants of CSR practised by non-Western firms in Nigeria have had negative or positive impacts in the oil and gas industry especially with China’s contribution to Nigerian economy.
Jaw Cycles and Linguistic Syllables in Adult English

Overview In this chapter, we examine whether ideas from Professor MacNeilage's apply to linguistic syllables in adult speech. The relevant ideas are that jaw movement is independent of segmental articulation, and that the jaw is recruited to help solve the serial order problem for speech. Specifically, MacNeilage argues that in ontogeny and phylogeny speech-like behavior-the production of consonant-vowel strings-first emerges when phonation is married to the cyclic open-close movement of the jaw. The result of this marriage is the proto-syllable: a structured segment grouping, which becomes elaborated with time as motor
Cultivating reflexivity in social work students: A course-based experience

Social work educators are concerned about how best to equip social work students with the ability to self-reflect, because this is a core professional competence. The present study employed both quantitative and qualitative means to evaluate a course which set out to foster reflexivity among social work undergraduates. A quasi-experimental design was employed to examine the effectiveness of the course. Data were collected at pre-course, post-course, and 6 months after completion. We found that, over time, students in the experimental group gained more insight. The students disclosed in focus group interviews that the course had enhanced their understanding toward self, family, and society. The implications for social work education are discussed.
Socioeconomic Inequalities in Non-Communicable Diseases and Self Assessed Health in Turkey

Abstract Background Inequities in health need to be monitored and necessary actions should be taken to reduce them. This study aimed to determine the socioeconomic distribution of self-reported chronic diseases and self-assessed health (SAH) in Turkey and try to evaluate the determinants of such inequalities in terms of their contributions. Methods Cross-sectional data from the Turkish Health Survey conducted during year 2008, covering 14,655 adults aged 15 or older were analyzed for the first time to assess socioeconomic inequalities in chronic disease and suboptimal SAH prevalence by calculating concentration index (CI), which ranges from -1 to +1 (concentration of disease among lower and higher socioeconomic groups) and the relative index of inequality (RII), reflecting the prevalence ratio between the two extremes of wealth. Results Several diseases and sub-optimal SAH were more concentrated among those with lower incomes. The concentration indices of chronic obstructive pulmonary disease (COPD), arthritis, chronic bronchitis, migraine and poor SAH were -0.180 (95% CI = -0.241,-0.111), -0.126 (95% CI = -0.148,-0.105),-0.118 (95%CI = -0.149,-0.079), -0.248(95%CI = (-0.278,-0.219) respectively. Of all chronic diseases, COPD demonstrated the highest relative inequality with a RII value of 2.51 (95%CI: 1.57-4.01). Income was the major contributor to inequality in occurrence of COPD (88.2%), migraine (80.4%) and arthritis (77.7%). Conclusion The findings indicate that majority of chronic diseases were more concentrated among less wealthy individuals in Turkey. Wealth and education had the largest contributions to observed inequalities. These inequalities need to be explicitly addressed and vulnerable subgroups should be targeted to reduce these socioeconomic disparities.
A qualitative study of HIV serodiscordant patients accessing assisted reproductive treatment

Objective: To explore the medical and psychosocial experiences of HIV serodiscordant patients attending an Assisted Reproductive Treatment (ART) programme. Design: Twenty couples in treatment from June 2008 to June 2009 were sent written invitations to participate in the study. Method: A semi-structured interview investigating the client’s HIV history, family decision-making, engagement with and experiences of the programme was conducted. Interviews were transcribed verbatim and thematic content analysis was used. Results: Six couples expressed an interest to participate in the study, with a final sample of 10 participants comprising of 4 couples and 2 individuals. Participants demonstrated varying levels of understanding in relation to the medical implications of treatment including vertical and horizontal transmission risks and ART procedures. Infertility-related stresses were highlighted including the quality of the couple’s interpersonal relationships, the emotional, physical and financial burden of treatment and the impact of fertility treatment on their work/life balance. Disclosure of HIV status and managing confidentiality were also significant challenges for participants of this programme. Conclusion: Participants’ experiences of the programme have been positive, though varied. They expressed high expectations of the programme, particularly regarding the likelihood of a pregnancy. HIV was not seen by the clients to be a clinical indicator for infertility.
In Metabolic Engineering of Eukaryotic Microalgae: Potential and Challenges Come with Great Diversity

The great phylogenetic diversity of microalgae is corresponded by a wide arrange of interesting and useful metabolites. Nonetheless metabolic engineering in microalgae has been limited, since specific transformation tools must be developed for each species for either the nuclear or chloroplast genomes. Microalgae as production platforms for metabolites offer several advantages over plants and other microorganisms, like the ability of GMO containment and reduced costs in culture media, respectively. Currently, microalgae have proved particularly well suited for the commercial production of omega-3 fatty acids and carotenoids. Therefore most metabolic engineering strategies have been developed for these metabolites. Microalgal biofuels have also drawn great attention recently, resulting in efforts for improving the production of hydrogen and photosynthates, particularly triacylglycerides. Metabolic pathways of microalgae have also been manipulated in order to improve photosynthetic growth under specific conditions and for achieving trophic conversion. Although these pathways are not strictly related to secondary metabolites, the synthetic biology approaches could potentially be translated to this field and will also be discussed.
SWISS-MODEL: modelling protein tertiary and quaternary structure using evolutionary information

Protein structure homology modelling has become a routine technique to generate 3D models for proteins when experimental structures are not available. Fully automated servers such as SWISS-MODEL with user-friendly web interfaces generate reliable models without the need for complex software packages or downloading large databases. Here, we describe the latest version of the SWISS-MODEL expert system for protein structure modelling. The SWISS-MODEL template library provides annotation of quaternary structure and essential ligands and co-factors to allow for building of complete structural models, including their oligomeric structure. The improved SWISS-MODEL pipeline makes extensive use of model quality estimation for selection of the most suitable templates and provides estimates of the expected accuracy of the resulting models. The accuracy of the models generated by SWISS-MODEL is continuously evaluated by the CAMEO system. The new web site allows users to interactively search for templates, cluster them by sequence similarity, structurally compare alternative templates and select the ones to be used for model building. In cases where multiple alternative template structures are available for a protein of interest, a user-guided template selection step allows building models in different functional states. SWISS-MODEL is available at http://swissmodel.expasy. org/.
Getting closer to a pre-vertebrate genome: the non-LTR retrotransposons of Branchiostoma floridae

Non-LTR retrotransposons are common in vertebrate genomes and although present in invertebrates they appear at a much lower frequency. The cephalochordate amphioxus is the closest living relative to vertebrates and has been considered a good model for comparative analyses of genome expansions during vertebrate evolution. With the aim to assess the involvement of transposable elements in these events, we have analysed the non-LTR retrotransposons of Branchiostoma floridae. In silico searches have allowed to reconstruct non-LTR elements of six different clades (CR1, I, L1, L2, NeSL and RTE) and assess their structural features. According to the estimated copy number of these elements they account for less than 1% of the haploid genome, which reminds of the low abundance also encountered in the urochordate Ciona intestinalis. Amphioxus (B. floridae) and Ciona share a pre-vertebrate-like organization for the non-LTR retrotransposons (<150 copies, < 1% of the genome) versus the complexity associated to higher vertebrates (Homo sapiens >1.3·106 copies, > 20% of the genome).
Tensor-GMRES method for large sparse systems of nonlinear equations

This paper introduces a tensor-Krylov method, the tensor-GMRES method, for large sparse systems of nonlinear equations. This method is a coupling of tensor model formation and solution techniques for nonlinear equations with Krylov subspace projection techniques for unsymmetric systems of linear equations. Traditional tensor methods for nonlinear equations are based on a quadratic model of the nonlinear function, a standard linear model augmented by a simple second order term. These methods are shown to be significantly more efficient than standard methods both on nonsingular problems and on problems where the Jacobian matrix at the solution is singular. A major disadvantage of the traditional tensor methods is that the solution of the tensor model requires the factorization of the Jacobian matrix, which may not be suitable for problems where the Jacobian matrix is large and has a 'bad' sparsity structure for an efficient factorization. We overcome this difficulty by forming and solving the tensor model using an extension of a Newton-GMRES scheme. Like traditional tensor methods, we show that the new tensor method has significant computational advantages over the analogous Newton counterpart. Consistent with Krylov subspace based methods, the new tensor method does not depend on the factorization of the Jacobian matrix. As a matter of fact, the Jacobian matrix is never needed explicitly.
A Diffusion Strategy for the Multichannel Active Noise Control System in Distributed Network

This paper introduces a diffusion strategy for the multichannel active noise control. The diffusion strategy is designed to reduce the computational complexity by distributes computations to all nodes of multichannel active noise control system. Thus, the multichannel filtered-x normalized least mean square algorithm, which is the simplest way for real active noise control environments is used as a base algorithm for the diffusion strategy. From the structure of the multichannel active noise control system, the optimal weight vector at a node of the proposed strategy is calculated by considering the weight vector of neighbor nodes. With the proposed strategy, the computational complexity is distributed from one main processor to all nodes. With some simulation results, the performance of the proposed strategy is shown with the reduced computational complexity for one processor.
Syntactic Acquisition in Bilingual Children

Recent research on pragmatic and syntactic development in bilingual 2-year-olds has shown that these children have differentiated language systems. However, it remains to be shown whether their grammars develop autonomously or interdependently from 2 years onward. The present study investigates the potential interference between the grammars of French-English bilingual children, aged 2–3 years. We examined their acquisition of functional categories, specifically the properties of INFL (finiteness and agreement) and negation, as these grammatical properties differ in both adult French and English and child French and English. Our results indicate that the bilingual children show no evidence of transfer, acceleration, or delay in acquisition, and support the hypothesis that their grammars are acquired autonomously. Some implications of these findings for the debate on continuity in the emergence of functional categories are discussed.
Comparing remotely sensed and modelled aerosol properties for a region of low aerosol optical depth

Studies of the second indirect aerosol effect (pollution inhibiting stratiform rainfall) for city size scale during a rain event are rare. However, as urban footprints expand understanding of urbanization effects on meteorology is crucial to mitigate possible adverse impacts such as modification to local cloud cover and precipitation. Here we compare aerosol optical properties from five weather model combinations of chemistry transport schemes with satellite images of aerosol optical properties in clear sky conditions. The WRF-Chem MOSAIC/CBM-Z combination of gas phase chemistry and aerosol transport schemes are shown to correlate well with a MODIS image for the case study presented. The result is important because the study area of Brisbane, Australia is known to have a low aerosol load - creating limitations when correlating model and satellite images of aerosol size distribution. Accordingly, results pave the way for future studies to quantify aerosol impacts on cloud and precipitation in sub-tropical settings.
On the network geography of the Internet

The geographic layout of the physical Internet inherently determines important network properties and traffic characteristics. To give insight into the geography of the Internet, we examine the spatial properties of the topology and routing. To represent the network we conducted a geographically dispersed traceroute campaign, and embedded the extracted topology into the geographic space by applying a novel IP geolocalization service, called Spotter. In this paper we present the frequency analysis of link lengths, quantify path circuitousness and explore the symmetry of end-to-end Internet routes.
Large-Scale Cloud Radio Access Networks with Practical Constraints: Asymptotic Analysis and Its Implications

Large-scale cloud radio access network (LS-CRAN) is a highly promising next-generation cellular network architecture whereby lots of base stations (BSs) equipped with a massive antenna array are connected to a cloud-computing based central processor unit via digital front/backhaul links. This paper studies an asymptotic behavior of downlink (DL) performance of a LS-CRAN with three practical constraints: 1) limited transmit power, 2) limited front/backhaul capacity, and 3) limited pilot resource. As an asymptotic performance measure, the scaling exponent of the signal-to-interference-plus-noise-ratio (SINR) is derived for interference-free (IF), maximum-ratio transmission (MRT), and zero-forcing (ZF) operations. Our asymptotic analysis reveals four fundamental operating regimes and the performances of both MRT and ZF operations are fundamentally limited by the UL transmit power for estimating user's channel state information, not the DL transmit power. We obtain the conditions that MRT or ZF operation becomes interference-free, i.e., order-optimal with three practical constraints. Specifically, as higher UL transmit power is provided, more users can be associated and the data rate per user can be increased simultaneously while keeping the order-optimality as long as the total front/backhaul overhead is $\Omega(N^{\eta_{\rm{bs}}+\eta_{\rm{ant}}+\eta_{\rm{user}}+\frac{2}{\alpha}\rho^{\rm{ul}}})$ and $\Omega(N^{\eta_{\rm{user}}-\eta_{\rm{bs}}})$ pilot resources are available. It is also shown that how the target quality-of-service (QoS) in terms of SINR and the number of users satisfying the target QoS can simultaneously grow as the network size increases and the way how the network size increases under the practical constraints, which can provide meaningful insights for future cellular systems.
Attempted Suicide and Creative Promise

This article begins by discussing the creative problems of four individuals from four different countries and the problems and pressures which led to their suicide attempts. A proportion of suicide attempts are disguised as accidents and are not recorded in official reports, which results in under-reporting of suicide attempts. In the last twenty years the suicide rate among youths 15–24 years has risen three hundred percent. Suicide is second only to automobile accidents as the leading cause of death of this age group. The creatively gifted are particularly vulnerable to the boredom and depression which accompanies isolation during the adolescent years and earlier. This combined with parents and peers' expectations and the inability to find meaningful career opportunities poses numerous problems for the creatively gifted and often result in the drastic decision that life has no more to offer. It is our contention that suicide attempts among the creatively gifted is the “tip of the iceberg”. We also express our concern for the creatively gifted who have not committed the final telo de se but have first of all stopped being creative and then have stopped living. We suggest that this is a form of suicide.
Mental Rotation Meets the Motion Aftereffect: The Role of hV5/MT+ in Visual Mental Imagery

A growing number of studies show that visual mental imagery recruits the same brain areas as visual perception. Although the necessity of hV5/MT+ for motion perception has been revealed by means of TMS, its relevance for motion imagery remains unclear. We induced a direction-selective adaptation in hV5/MT+ by means of an MAE while subjects performed a mental rotation task that elicits imagined motion. We concurrently measured behavioral performance and neural activity with fMRI, enabling us to directly assess the effect of a perturbation of hV5/MT+ on other cortical areas involved in the mental rotation task. The activity in hV5/MT+ increased as more mental rotation was required, and the perturbation of hV5/MT+ affected behavioral performance as well as the neural activity in this area. Moreover, several regions in the posterior parietal cortex were also affected by this perturbation. Our results show that hV5/MT+ is required for imagined visual motion and engages in an interaction with parietal cortex during this cognitive process.
Response types and the prosody of declaratives

This paper presents a production study of declarative responses in varying dialogue contexts. The goal was to determine what sort of dialogue conditions produce systematic variations in prosody, and what these variations mean for discourse interpretation. After controlling for information structural factors, we found that distinct prosodic forms were predictably and consistently elicited by varying the response type of the utterance. In particular, we found that indirect agreements/contradictions were produced with a distinct intonational form compared to to direct responses. We quantify the prosodic separability of these response types via classification experiments, comparing the usefulness of both aggregate features, e.g. mean and variance, and features derived from function decomposition techniques. We find that the latter approach allows us for a more succinct description of category differences in terms of tilt and convexity.
Human Neuroscience

the same goal (about two-thirds of mirror neurons). About 17% of mirror neurons have auditory, as well as visual and motor properties (Kohler et al., 2002). Several experiments with macaques suggest a role for mirror neurons in action goal recognition. For example, a mirror neuron will be active when an action on an object is completed behind a barrier, but not when the animal knows that there is no object behind the barrier (Umiltà et al., 2001). Also, a mirror neuron will fire when pliers operated by the animal close on a target, and the same neuron is active when the pliers operate by a hand-closing or a hand-opening movement (Umiltà et al., 2008). Thus, it is the goal that counts, not the specific movements for achieving the goal. Because of the relative scarcity of single cell recording in humans (but see Mukamel et al., 2010), much of the human mirror neuron literature uses functional magnetic resonance imaging (fMRI). In this case, the operation of MMs is inferred when activity in a particular cortical area (as reflected in the BOLD signal) is similar during action recognition and action production, and when the cortical area is a likely homolog of an area in macaque cortex in which mirror neurons have been identified. Using this or a similar logic, it appears that the human MMs respond more to actions that the perceiver can perform than to actions the perceiver is familiar with through vision alone (Calvo-Merino et al., 2006); MMs are more sensitive to social actions than similar non-social actions (Kilner et al., 2006); MMs respond to both visually perceived actions and the linguistic description of actions (Tettamanti et al., 2005); MMs play a role in speech perception (D'Ausilio et al., 2009); activity in MMs is positively correlated with empathy (Gazzola et al., 2006) and negatively correlated with autistic behaviors (Dapretto et al., 2006). Nonetheless, there are reasons to be skeptical. Namely, fMRI data cannot clearly demonstrate that the same neurons are contributing to both action production and action recognition, only that a
