'Switching and swapping faces': performativity and emotion in midwifery

Managing and performing emotions to support women service users and colleagues can leave midwives feeling emotionally drained. The necessity to 'perform' emotion, associated with reorganisations in the National Health Service (NHS) in the United Kingdom (UK), has contributed towards a prevailing understanding of clinical practice as performance based. In this paper, two types of emotional work within midwifery are explored: 'emotional labour' and 'philanthropic emotion work'. Data from two studies in the north of England are presented. In-depth interviews and focus groups were conducted with midwives and subsequently analysed using thematic analysis. The findings indicate that emotional labour and philanthropic emotional work are unacknowledged and undervalued within midwifery. In addition, this has negative repercussions for the quality of the service provided whilst also undermining the creation of an emotionally and intellectually sustaining working environment for midwives.
Visual discourse analysis in historical research: a case of visual archaeology?

In this essay I complement the methodological practice of organizational discourse studies. My contribution lies in using visual discourse analysis in a historical research setting – I call this methodological approach ‘visual archaeology’. I highlight this method by reporting an empirical case from the presidential leadership of Urho Kekkonen of Finland. After going through the research process of my study, I present the emergent photo-essay, showing and explaining my theoretical reading of the empirical material that I collected. The essay concludes with a discussion of the contributions of this approach for the practice of conducting visual discourse studies in historical organizational research.
Parents' experiences of the Lidcombe Program of early stuttering intervention

The Lidcombe Program is a parent-based behavioural treatment for early stuttering. Quantitative studies have shown it is an efficacious treatment for eliminating stuttering in children of 6 years and younger. This study explores parents' experiences in order to understand more about the process of implementing the Lidcombe Program. Twenty-one in-depth qualitative interviews took place with parents of 14 children who showed a range of responses to treatment. Six parents were interviewed twice so that changes over time could provide further insights. The data was analysed using an inductive approach supported by NVivo qualitative software. This interview data suggests that parents' experiences of the Lidcombe Program are influenced by their ways of making sense of the principles and procedures of the programme and how these fit with their understanding of stuttering, parenting and their children who stutter. Parents experience the Lidcombe Program as satisfying and relatively simple when therapy proceeds straightforwardly. When progress is slower or erratic parents perceive the treatment as more complex and confusing. Failure to adequately address difficulties with the Lidcombe Program can reduce its therapeutic impact and lead to parental distress. These parents' perspectives provide knowledge about the Lidcombe Program that is not recorded in the published quantitative studies.
Protest, Deterrence, and Escalation: The Strategic Calculus of Government Repression

The theoretical literature on government repression has mostly taken a choice theoretic perspective, wherein either the protest group optimally chooses a protest tactic in response to government behavior or the government optimally chooses a repression strategy. This approach is insufficient for capturing the strategic nature of protest and repression. The theoretical shortcomings of this approach are reflected in contradictory empirical findings on the effects of repression on dissent. The article develops an extensive strategic game between the government and an opposition group that allows one to identify the conditions for successful deterrence or protest. Introducing incomplete information and a third-party threat additionally produces equilibria with repression and escalating violence. The model produces novel testable hypotheses that shed new light on the effect of repression on dissent, the likelihood of violence, and the possibility of a coup. Implications for the domestic democratic peace and “murder in the middle” hypothesis are drawn.
The B subunit of the DNA polymerase alpha-primase complex in Saccharomyces cerevisiae executes an essential function at the initial stage of DNA replication

The four-subunit DNA polymerase alpha-primase complex is unique in its ability to synthesize DNA chains de novo, and some in vitro data suggest its involvement in initiation and elongation of chromosomal DNA replication, although direct in vivo evidence for a role in the initiation reaction is still lacking. The function of the B subunit of the complex is unknown, but the Saccharomyces cerevisiae POL12 gene, which encodes this protein, is essential for cell viability. We have produced different pol12 alleles by in vitro mutagenesis of the cloned gene. The in vivo analysis of our 18 pol12 alleles indicates that the conserved carboxy-terminal two-thirds of the protein contains regions that are essential for cell viability, while the more divergent NH2-terminal portion is partially dispensable. The characterization of the temperature-sensitive pol12-T9 mutant allele demonstrates that the B subunit is required for in vivo DNA synthesis and correct progression through S phase. Moreover, reciprocal shift experiments indicate that the POL12 gene product plays an essential role at the early stage of chromosomal DNA replication, before the hydroxyurea-sensitive step. A model for the role of the B subunit in initiation of DNA replication at an origin is presented.
People’s responses to risks of electromagnetic fields and trust in government policy: the role of perceived risk, benefits and control

Trust in government policy affects the way people perceive and handle risks. In our study, we investigated the relationships between trust in government policy regarding electromagnetic fields (EMF), perceived risk and perceived benefits of public and personal EMF sources, perceived control over exposure to EMF and responses to the possible EMF health risk (e.g. protest against placement of mobile phone base stations or power lines, or taking own measures against EMF exposure). Previous research indicated that perceived risk and benefits mediate the relationship between trust and people’s risk responses. Additionally, we suggest that perceived control over EMF exposure affects the relation between trust in government policy and perceived risk, and, consequently, the risk responses. We performed a survey among the Dutch population (n = 1009), which contained questions about risk responses to EMF, perceived risk and benefits of several EMF sources, trust in government policy and perceived control over EMF exposure. Comparing public EMF sources, i.e. power lines and mobile phone base stations, to personal EMF sources, i.e. microwave ovens and cordless and mobile phones, we tested our hypotheses. Variations in risk responses to both public and personal EMF sources were mainly explained by risk perception. In addition, perceived risk partially mediated the relationship between trust in government policy and risk responses. For public sources, perceived control over exposure weakened the negative relationship between trust and perceived risk. We conclude that, especially in people with low perceived control, a lack of trust in government policy may enhance perceptions of health risks, thereby increasing their inclination for risk responses.
Five Year Life Expectancy Calculator for Older Adults

Incorporating accurate prognostic information into clinical decision making could advance evidence-based, person-centered healthcare by more effectively targeting healthcare services to those patients most likely to benefit. Here we describe the deployment of predictive models for five year life expectancy of patients, built on electronic health records (EHR) of nearly 7,500 patients aged 50 and above, with one or more visits to a large, academic, multispeciality hospital in a year, exploring more than 75 modeling configurations. The online web-tool takes a non-redundant subset of 24 patient attributes as input and generates a patient-specific prediction of 5-year survival. The online five year life expectancy calculator is available at http://info.eecs. northwestern.edu/FiveYearLifeExpectancyCalculator.
Efficient computation of buffer capacities for multi-rate real-time systems with back-pressure

A key step in the design of multi-rate real-time systems is the determination of buffer capacities. In our multi-processor system, we apply back-pressure as caused by bounded buffers in order to control jitter. This requires the derivation of buffer capacities that both satisfy the temporal constraints as well as constraints on the buffer capacity. Existing exact solutions suffer from the computational complexity associated with the required conversion from a multi-rate dataflow graph to a single-rate dataflow graph. In this paper we present an algorithm, with linear computational complexity, that does not require this conversion and that determines close to minimal buffer capacities. The algorithm is applied to an MP3 play-back application that is mapped on our network based multi-processor system.
Reporting Intentional Rating of the Primes Predicts Priming Effects in the Affective Misattribution Procedure

In the affective misattribution procedure (AMP), pairs of prime and target stimuli appear rapidly in succession. Attitudes toward the prime influence the evaluation of the target despite instructions to avoid this influence. Because this priming effect presumably happens without people’s knowledge, the AMP is used to study automatic evaluation. Participants in four studies performed the AMP and reported their perception of the priming effect. The authors found that the priming reflected reliable and valid attitudes toward the primes mostly among participants who reported that the priming occurred and that they intentionally rated the primes instead of the targets. The authors conclude that the AMP hardly captures attitude effects that escape people’s knowledge. The AMP’s good psychometric qualities as an attitude measure rely mainly on a small subset of participants who believe that they intentionally caused the attitude effect.
Poly[diaquabis(μ3-1H-benzimidazole-5,6-dicarboxylato-κ4 N 3:O 5,O 5′:O 6)bis(μ2-1H,3H-benzimidazolium-5,6-dicarboxylato-κ3 O 5,O 5′:O 6)digadolinium(III)]

In the title complex, [Gd2(C9H4N2O4)2(C9H5N2O4)2(H2O)2]n, two of the benzimidazole-5,6-dicarboxylate ligands are protonated at the imidazole groups. Each GdIII ion is coordinated by six O atoms and one N atom from five ligands and one water molecule, displaying a distorted bicapped trigonal-prismatic geometry. The GdIII ions are linked by the carboxylate groups and imidazole N atoms, forming a layer parallel to (001). These layers are further connected by O—H⋯O and N—H⋯O hydrogen bonds into a three-dimensional supramolecular network.
Clinical utility of ambulatory blood pressure monitoring in the management of hypertension

Accurate blood pressure (BP) measurement is essential for the diagnosis, monitoring and management of hypertension. However, conventional office-based BP readings have several limitations that include a low reproducibility, the white-coat effect and the existence of masked hypertension. These limitations can be addressed through the use of ambulatory BP monitoring. Because ambulatory monitoring provides measurements at specific time intervals throughout a 24-hour period, this technique represents a better picture of the normal fluctuations in BP levels associated with daily activities and sleep. In addition, end-organ damage associated with hypertension is more closely related to ambulatory BP than office BP measurements and ambulatory BP profile give better prediction of clinical outcome than conventional BP measurements.
Approaching low liver iron burden in chelated patients with non-transfusion-dependent thalassemia: the safety profile of deferasirox

Patients with non‐transfusion‐dependent thalassemia (NTDT) often develop iron overload and related complications, and may require iron chelation. However, the risk of over‐chelation emerges as patients reach low, near‐normal body iron levels and dose adjustments may be needed. In the THALASSA study, the threshold for chelation interruption was LIC <3 mg Fe/g dw (LIC<3); 24 patients receiving deferasirox for up to 2 yr reached this target. A post hoc analysis was performed to characterize the safety profile of deferasirox as these patients approached LIC<3.
A quasi-orthogonal group space-time architecture for higher diversity gains

Multiple-input multiple-output (MIMO) systems can provide two kinds of gain: diversity gain and multiplexing gain. Most existing MIMO schemes, including space-time coding and layered space-time, aim at maximizing either of them. Therefore, it is desirable to design a scheme to get a better tradeoff between the multiplexing gain and diversity gain. In this paper, a novel quasi-orthogonal group space-time (QOGST) architecture is proposed. In QOGST, the transmit stream is divided into several groups and all the groups are encoded via an inter-group space-time block encoder. Group interference suppression is adopted at the receiver. Performance is evaluated in terms of symmetric energy and it is shown that compared to the group layered space-time (GLST) architecture, the proposed QOGST can achieve a higher symmetric energy and a better diversity-multiplexing tradeoff. Simulation results validate our analysis and show that QOGST can achieve at least 3 dB gain over GLST at a FER of 10/sup -3/, for instance.
Racial/Ethnic Disparities in Influenza Vaccination of Chronically Ill US Adults: The Mediating Role of Perceived Discrimination in Health Care

Background:Despite well-established programs, influenza vaccination rates in US adults are well below federal benchmarks and exhibit well-documented, persistent racial and ethnic disparities. The causes of these disparities are multifactorial and complex, though perceived racial/ethnic discrimination in health care is 1 hypothesized mechanism. Objectives:To assess the role of perceived discrimination in health care in mediating influenza vaccination RACIAL/ETHNIC disparities in chronically ill US adults (at high risk for influenza-related complications). Research Design:We utilized 2011–2012 data from the Aligning Forces for Quality Consumer Survey on health and health care (n=8127), nationally representative of chronically ill US adults. Logistic regression marginal effects examined the relationship between race/ethnicity and influenza vaccination, both unadjusted and in multivariate models adjusted for determinants of health service use. We then used binary mediation analysis to calculate and test the significance of the percentage of this relationship mediated by perceived discrimination in health care. Results:Respondents reporting perceived discrimination in health care had half the uptake as those without discrimination (32% vs. 60%, P=0.009). The change in predicted probability of vaccination given perceived discrimination experiences (vs. none) was large but not significant in the fully adjusted model (−0.185; 95% CI, −0.385, 0.014). Perceived discrimination significantly mediated 16% of the unadjusted association between race/ethnicity and influenza vaccination, though this dropped to 6% and lost statistical significance in multivariate models. Conclusions:The causes of persistent racial/ethnic disparities are complex and a single explanation is unlikely to be sufficient. We suggest reevaluation in a larger cohort as well as potential directions for future research.
Improving code density of embedded software using a 2-level dictionary code compression architecture

Dictionary code compression has been proposed to reduce the energy consumed in the instruction fetch path of processors or to reduce program footprint in memory. With this technique, instructions, or instruction sequences, are in the binary code replaced with short code words that in run-time are replaced with the original instructions using the dictionary inside the data-path. We present here a new method with the aim to further improve on code density as compared to previously proposed dictionary code compression techniques. It is a 2-level approach capable of handling compression of both individual instructions and code sequences of 2-16 instructions. Our proposed approach is more flexible and has better dynamic compression ratio and fetch path energy consumption as compared to previously studied 1-level approaches. The energy consumed in the instruction fetch path is reduced with up to 56% as compared to using uncompressed instructions.
Dynamic bandwidth allocation for efficient transport of real-time VBR video over ATM

The paper presents a novel approach to dynamic transmission bandwidth allocation for transport of real-time variable-bit-rate video in ATM networks. The authors describe video traffic in the frequency domain: the low frequency signal captures the slow time-variation of consecutive scene changes; the high frequency signal exhibits the feature of strong frame autocorrelation. The study indicates that the video transmission bandwidth in a finite-buffer system is essentially characterized by the low, frequency signal. Since the time scale of scene changes is usually in the range of a second or longer, the low frequency video signal is defined in a well-founded low frequency band. Hence, it is feasible to implement dynamic allocation of video transmission bandwidth using on-line observation and prediction of scene changes. Two prediction schemes are examined: the recursive least square method vs. the time delay neural network method. A time delay neural network with low-complexity high-order architecture, called a "pi-sigma network", is successfully used to predict scene changes. The proposed dynamic bandwidth allocation scheme is shown to be promising and practically feasible in obtaining efficient transmission of real-time video traffic with guaranteed quality of services. <<ETX>>
Multiple camera types simultaneous stereo calibration

Calibration is a classical issue in computer vision needed to retrieve 3D information from image measurements. This work presents a calibration approach for hybrid stereo rig involving multiple central camera types (perspective, fisheye, catadioptric). The paper extends the method of monocular perspective camera calibration using virtual visual servoing. The simultaneous intrinsic and extrinsic calibration of central cameras rig, using different models for each camera, is developed. The presented approach is suitable for the calibration of rigs composed by N cameras modelled by N different models. Calibration results, compared with state of the art approaches, and a 3D plane estimation application, allowed by the calibration, show the effectiveness of the approach. A cross-platform software implementing this method is available1.
Effect of local immunotherapy of syngeneic rat fibrosarcoma with hapten and antihapten-tumor serum upon nonlocally treated tumor.

Abstract Previously, we produced complete regression of allogeneic and syngeneic rat tumors by in situ tumor modification with a hapten, l-phenylalanine mustard (PhM), followed by i.v. administration of an antiserum developed against PhM-tumor extract conjugate. To evaluate the effect of this local treatment on untreated tumors, only one of two syngeneic methylcholanthrene-induced rat fibrosarcomas transplanted to both thighs of Lewis rats was treated. The syngeneic antiserum produced against the conjugate of PhM and fibrosarcoma extract contained PhM-specific antibody and a barely detectable level of antibody specific to the conjugate. All of the paired tumors in untreated rats progressively grew and killed the hosts. Intratumoral (i.t.) injection of PhM only to the left tumor followed by i.v. administration of the antiserum produced uniform regression of all tumors, with disappearance of both treated (6 of 11 animals) and untreated (9 of 11 animals) tumors and prolonged survival time. Of the tumors which disappeared, three treated and five untreated tumors did not recur, and two rats were cured. The substitution of antiserum with normal serum or the substitution of the i.t. injection of PhM with s.c. PhM injection resulted in a significantly lower effect on both paired tumors, and there were no cures, indicating that the combination of i.t. injection of PhM and antiserum is important for successful tumor regression. Regression of the uninjected tumor was significantly greater in the PhM i.t. -antiserum group than in any other PhM-injected group. This difference cannot be explained by a systemic effect of PhM. In addition, the effect of PhM i.t. -antiserum on the uninjected right side tumor was markedly reduced by the excision of PhM-injected left side tumor. These results suggest that treated and retained regressing tumor tissue may be beneficial for the regression of the uninjected tumor. Interestingly, each pair of tumors synchronously changed its volume with a highly significant positive linear correlation, regardless of treatment modality, differences in tumor growth patterns, or differences in initial sizes of the paired tumors. In the PhM i.t. -antiserum group, this correlation seems to suggest the induction of systemic effects by the local treatment.

This study employs technology acceptance model to develop a unified theoretical model. Then empirical data which is collected from questionnaire and Structural Equation Modeling (SEM) is used to test the conceptual model. The results indicate that the usage experience have positive effect on difference of perceived ease of use and of perceived usefulness while those difference positively effects on the acceptance of the optional ways of information exchange. And the Similarity between the optional ways of information exchange has negative moderating effect on the first relationship.
MicroRNA-33b Suppresses Migration and Invasion by Targeting c-Myc in Osteosarcoma Cells

MicroRNAs have emerged as fundamental regulators in gene expression through silencing gene expression at the post-transcriptional and translational levels. Osteosarcoma is the most common type of primary malignant bone tumor and is characterized by complex genetic changes and resistance to conventional treatments. In our study, the role of miR-33b in the progression and metastasis of osteosarcoma was investigated. Our results showed that miR-33b was significantly downregulated in osteosarcoma tissue and cell lines. Overexpression of miR-33b significantly inhibited cell proliferation, migration, and invasion in the MG-63 osteosarcoma cell line. Moreover, we also showed that c-Myc was negatively regulated by miR-33b at the posttranscriptional level, via a specific target site within the 3′UTR. Overexpression of c-Myc impaired miR-33b-induced inhibition of proliferation and invasion in osteosarcoma cells. The expression of c-Myc was frequently downregulated in osteosarcoma tumors and cell lines and was inversely correlated with miR-33b expression. Thus, our findings suggest that miR-33b inhibits osteosarcoma cells migration and invasion by targeting the c-Myc gene, acting as tumor suppressor. The findings of this study contribute to current understanding of the functions of miR-33b in osteosarcoma.
