Determinants of Management Earnings Forecasts: The Case of Global Shipping IPOs
Authors: Drobetz Wolfgang , Gounopoulos Dimitrios , Merika Anna , Merikas Andreas 
Published: May 2017

AbstractFirms that go public on global stock markets are not obliged to disclose earnings forecasts in their prospectuses. We use this fact to examine the shipping industry, where most firms voluntarily issue earnings forecasts during the IPO process, thus providing unique, international‐level evidence. We find overall pessimistic forecasts of ship owners, primarily because of the industry's uncertain and volatile environment. High ship owner participation after going public is associated with less accurate earnings forecasts. Our results further indicate that financial leverage, a listing in an emerging stock market, and global market conditions are other main factors responsible for inaccurate earnings forecasts.

AbstractThe inclusion of legumes in semi‐arid native grasslands may promote the productivity and nutritive value of forage. This study was designed to assess the effect of legumes (the introduced legume Medicago sativa or the native legume Dalea purpurea) and soil P fertility (addition of 0, 50, or 200 P2O5 kg/ha at seeding) on the dry matter and nutrient content of native grasses mixtures, compared with the commonly used introduced forage grass Bromus biebersteinii grown with M. sativa. Plant harvests were performed in September 2008, July 2009 and September 2009. Plants nutrient content, δ15N value and dry matter were analysed. Results show that the M. sativa enhanced the N and P concentrations of native grass mixtures early in the summer, as well as the N concentration in Bouteloua gracilis in late summer of the driest year, 2009. The higher AM fungal diversity promoted by M. sativa was positively correlated with the dry matter and nitrogen uptake of M. sativa and with the P concentration of native grasses, in early summer. Overall, this study shows that M. sativa promoted beneficial AM fungal taxa and improved forage production in the semi‐arid prairies.

AbstractBackgroundHelicobacter pylori infection has become more and more resistant to conventional first‐line treatment regimens. So, there is a considerable interest in evaluating new antibiotic combinations and regimens. Nitazoxanide is an anti‐infective drug with demonstrated activity against protozoa and anaerobic bacteria including H. pylori. This work is designed to evaluate the efficacy and safety of a unique triple nitazoxanide‐containing regimen as a treatment regimen in Egyptian patients with H. pylori infection.MethodsTwo hundred and 24 patients with upper gastrointestinal tract (GIT) dyspeptic symptoms in whom H. pylori ‐induced GIT disease was confirmed were included in the study. They have been randomized to receive either nitazoxanide 500 mg b.i.d., clarithromycin 500 mg b.i.d., and omeprazole 40 mg twice daily for 14 days or metronidazole 500 mg b.i.d., clarithromycin 500 mg b.i.d., and omeprazole 40  mg twice daily for 14 days. Laboratory evaluation for H. pylori antigen within the stool was performed 6 weeks after cessation of H. pylori treatment regimens to assess the response.ResultsThe response to treatment was significantly higher in group 1 of nitazoxanide treatment regimen than group 2 of traditional treatment regimen. One hundred and six cases (94.6%) of 112 patients who completed the study in group 1 showed complete cure, while only 63 cases (60.6%) of 104 patients who completed the study in group 2 showed the same response according to per‐protocol (PP) analysis (P<.001). The regimen was well tolerated by all the patients enrolled in the study.ConclusionNitazoxanide‐containing triple therapy is a promising therapy for the first‐line eradication of H. pylori.

Published: May 2017

Interactions with parents build the foundation for infants' social–emotional development. This study investigated coregulation of the interaction and quality of relationship between mothers and their 6‐month‐old full‐term (n = 43) and very low‐birthweight/preterm (VLBW/preterm; n = 44; ages corrected for prematurity) infants. The objectives were to examine (1) how coregulation changed following a perturbed interaction, (2) how coregulation differed between full‐term and VLBW/preterm infant–mother dyads, and (3) the association between coregulation and relationship quality. Coregulation was coded using the Revised Relational Coding System (Fogel et al., 2003). Quality of the relationship was measured using the Emotional Availability scales (Biringen et al., 2014; Carter et al., 1998). Dyads participated in the Still‐Face (SF) procedure (Tronick et al., 1978) consisting of two natural and one SF period where mothers assumed a neutral expression, refraining from interacting with their infants. Following the SF period, dyads engaged in more symmetrical and more disruptive patterns of coregulation. While full‐term dyads engaged in more sequential‐symmetrical, VLBW/preterm dyads engaged in more resonant‐symmetrical coregulation. These results suggest that VLBW/preterm dyads may show more emotional reactivity in their interactions than full‐term dyads; however, in both groups infant responsiveness and parenting stress influenced the types of coregulation exhibited.

AbstractOver the past decade, cell therapies have provided promising strategies for the treatment of ischaemic cardiomyopathy. Particularly, the beneficial effects of stem cells, including bone marrow stem cells (BMSCs), endothelial progenitor cells (EPCs), mesenchymal stem cells (MSCs), embryonic stem cells (ESCs), and induced pluripotent stem cells (iPSCs), have been demonstrated by substantial preclinical and clinical studies. Nevertheless stem cell therapy is not always safe and effective. Hence, there is an urgent need for alternative sources of cells to promote cardiac regeneration. Human villous trophoblasts (HVTs) play key roles in embryonic implantation and placentation. In this study, we show that HVTs can promote tube formation of human umbilical vein endothelial cells (HUVECs) on Matrigel and enhance the resistance of neonatal rat cardiomyocytes (NRCMs) to oxidative stress in vitro. Delivery of HVTs to ischaemic area of heart preserved cardiac function and reduced fibrosis in a mouse model of acute myocardial infarction (AMI). Histological analysis revealed that transplantation of HVTs promoted angiogenesis in AMI mouse hearts. In addition, our data indicate that HVTs exert their therapeutic benefit through paracrine mechanisms. Meanwhile, injection of HVTs to mouse hearts did not elicit severe immune response. Taken together, our study demonstrates HVT may be used as a source for cell therapy or a tool to study cell‐derived soluble factors for AMI treatment.

BackgroundAutism Spectrum Disorders (ASD) are highly heritable, but the exact etiological mechanisms underlying the condition are still unclear.MethodsUsing a multiple rater twin design in a large sample of general population preschool twins, this study aimed to (a) estimate the contribution of genetic and environmental factors to autistic traits, controlling for the possible effects of rater bias, (b) to explore possible sex differences in etiology and (c) to investigate the discordance in autistic traits in monozygotic and same‐sex dizygotic twin pairs. The Netherlands Twin Register collected maternal and paternal ratings on autistic traits from a general population of 38,798 three‐year‐old twins. Autistic traits were assessed with the DSM‐oriented Pervasive Developmental Problems scale of the Child Behavior Check List for preschoolers (1½–5 years).ResultsMother and fathers showed high agreement in their assessment of autistic traits (r = .60–.66). Differences between children in autistic traits were largely accounted for by genetic effects (boys: 78% and girls: 83%). Environmental effects that are unique to a child also played a modest role. Environmental effects shared by children growing up in the same family were negligible, once rater bias was controlled for. While the prevalence for clinical ASD is higher in boys than in girls, this study did not find evidence for striking differences in the etiology of autistic traits across the sexes. Even though the heritability was high, 29% of MZ twin pairs were discordant for high autistic traits (clinical range vs. normal development), suggesting that despite high genetic risk, environmental factors might lead to resilience, unaffected status in the context of genetic risk, in some children.ConclusionsIt is important to focus future research on risk factors that might interplay with a genetic disposition for ASD, but also on protective factors that make a difference in the lives of children at genetic risk.

Published: May 2017

BackgroundYouth with autism spectrum disorder (ASD) exhibit high rates of psychopathology. These symptoms can pose a risk of injury to self or others when the child is in crisis. Despite this danger, there are no instruments available to identify those with ASD who are at risk or actively in crisis. This study examined the psychometric properties of the Mental Health Crisis Assessment Scale (MCAS), a 28 item parent report measure.MethodsThe MCAS was administered to the parents of 606 children and young adults (aged 3–25 years, M age = 13 years, SD = 5 years) enrolled in the Interactive Autism Network, an online registry of families raising a child with ASD. The MCAS asks parents to rate the severity of various emotional and behavioral symptoms exhibited by their child. The parent then selects the behavior they perceive as the most dangerous behavior and rates the acuity of as well as their efficacy in managing this behavior. The MCAS was tested for internal consistency, construct validity, criterion validity, and convergent validity.ResultsThe MCAS demonstrated strong internal consistency (Total Scale Cronbach's α = .88). The exploratory and confirmatory factor analyses suggested that a two factor (acuity and behavioral efficacy) model fit the data well, providing evidence of construct validity. Criterion validity, which was assessed by comparing the MCAS to clinician determination of crisis, indicated high levels of agreement (ROC = .85). Strong positive relationships emerged between the MCAS and measures of family distress (r = .56), parental stress, and frustration (r = .48), and use of emergency psychiatric services (OR = 24.2, 95% CI: 8.6–68.2), indicating convergent validity of the measure (all p < .05).ConclusionsResults of the psychometric analyses suggest the MCAS appears to be a promising tool that can measure mental health crises in youth with ASD.

ABSTRACTBACKGROUND AND PURPOSEThe natural history of optic pathway glioma (OPG) is highly variable and unpredictable. We present a pilot study of the prognostic role of conventional and dynamic contrast‐enhanced magnetic resonance imaging (DCE MRI) in the evaluation of OPG.METHODSWe retrospectively reviewed 17 patients with 20 pretreatment OPG lesions who underwent conventional and DCE MRI between January 2010 and December 2016. Conventional MRI was evaluated for enhancement pattern, cystic component, optic nerve tortuosity, optic nerve dural ectasia, and optic nerve perineural thickening. The DCE MRI data were analyzed for quantitative parameters using the two‐compartment pharmacokinetic model (Ktrans, kep, and ve) and for semiquantitative parameters based on time‐signal intensity curve (AUC60, peak, and wash‐in). The results were compared with the clinically progressive or nonprogressive tumor.RESULTSFive progressive OPGs and 15 nonprogressive OPGs were included. Conventional MRI findings of diffuse enhancement and cystic component were significantly correlated with progressive OPGs (both P = .01). Conventional MRI yielded sensitivity of 60%, specificity of 100%, and accuracy of 90%. Ktrans, kep, and ve as well as AUC60, peak, and wash‐in were significantly higher in progressive OPGs (P < .05). Using DCE MRI increased diagnostic performance up to a sensitivity of 100%, specificity of 93%, and accuracy of 95%.CONCLUSIONDCE MRI accurately distinguished progressive and nonprogressive OPGs, with high sensitivities and specificities. DCE MRI has a significant prognostic role in predicting progressive OPGs, thus making it useful for the identification of patients who need close clinical and imaging follow‐up.

Published: May 2017

This study assessed whether trajectories of parental monitoring components were different for sexual minority girls (SMGs) compared to heterosexual girls. We recruited 14–19‐year‐old girls from two adolescent medicine clinics. We estimated growth curve models to compare how components of parental monitoring—adolescent disclosure, parental solicitation, and parental knowledge—changed over 2 years for SMGs and heterosexual girls. SMGs and heterosexual girls had similar trajectory slopes and quadratic forms of adolescent disclosure, but SMGs had consistently lower adolescent disclosure scores. Parental knowledge trajectories indicated differential intercepts and slopes for SMGs compared to heterosexual girls, suggesting potential higher risk for maladaptive behaviors. Results of this study suggest that parental monitoring may operate differently over time for SMGs compared to heterosexual girls.
Subtilisin‐like proteases in plant defence: the past, the present and beyond
Authors: Figueiredo Joana , Sousa Silva Marta , Figueiredo Andreia 
Published: May 2017

SummarySubtilisin‐like proteases (or subtilases) are a very diverse family of serine peptidases present in many organisms, but mostly in plants. With a broad spectrum of biological functions, ranging from protein turnover and plant development to interactions with the environment, subtilases have been gaining increasing attention with regard to their involvement in plant defence responses against the most diverse pathogens. Over the last 5 years, the number of published studies associating plant subtilases with pathogen resistance and plant immunity has increased tremendously. In addition, the observation of subtilases and serine protease inhibitors secreted by pathogens has also gained prominence. In this review, we focus on the active participation of subtilases in the interactions established by plants with the environment, highlighting their role in plant–pathogen communication.
“My Profession Chose Me:” Precarity, Pragmatism, and Professionalism in Caribbean and West African Immigrant Domestic Workers’ Narratives
Authors: Glaser Lee 
Published: May 2017

AbstractExtensive literature on care work or domestic work — childcare, eldercare, and housecleaning — in the United States and internationally has highlighted how the sector's affective aspects, e.g., intimacy, personalism, and fictive kin relationships, extract “surplus emotional labor” (Hochschild 1983) from women workers, who, in turn, often justify their caregiving labor through expressions of sentiment and kin obligation. In this article, I draw on three women's narrative framings of their domestic work jobs to argue that immigrant women in New York City emphasize structural, practical, and contextual elements of their domestic/caregiving labor, challenging constructions of care sector labor as evidence of innate caring aptitudes, womanly duty, or moral service. These characterizations have direct labor policy implications for paid care work — as evidenced in recent reforms. They also provide a theoretical basis for broader redistributive politics linking paid and unpaid caregiving labor.

Published: May 2017

ABSTRACTBackgroundDelirium is a serious complication in patients in intensive care units. Previous surveys on delirium management in daily practice showed low adherence to published guidelines.AimTo evaluate delirium management in nurses and physicians working in intensive care units in German‐speaking countries and to identify related differences between nurses and physicians.DesignThe study used an open online survey with multiple‐choice responses.MethodsAn invitation for participation was spread via journals and electronic resources using a snowball system. Apart from recording socio‐demographical characteristics, the survey collected data on delirium assessment, delirium‐related processes, non‐pharmacological prevention and treatment and barriers for implementation. Differences between nurses and physicians were tested by Fisher's exact test with sequential Bonferroni correction.ResultsThe survey was conducted in autumn 2016, and 559 clinicians participated. More nurses than physicians reported screening for delirium. The majority of clinicians reported screening for delirium when this was suspected; more than 50% used validated instruments. Half of the clinicians had delirium‐related structures implemented, such as two thirds reporting delirium‐related processes. Most cited barriers were lack of time and missing knowledge about delirium and its assessment. With significant difference, physicians recommended more than nurses early removal of catheters and daily interprofessional goals for patients.ConclusionIn German‐speaking countries, assessment of delirium needs further improvement, leading to accurate assessment. Delirium‐related structures and processes appear to be implemented widely, with only a few differences between nurses and physicians.Relevance to clinical practiceNurses and physicians in this survey reported similar perceptions and attitudes towards management of delirium. Both professions need more knowledge and inter‐professional training on when and how to use validated assessment instruments.

SummaryObjectiveThe objective of this study was to systematically review evidence to identify intrapersonal, social environmental, physical environmental and policy correlates of sedentary behaviour (SB) among adults.MethodsSix databases were searched to identify studies that reported on intrapersonal, social, physical environmental and/or policy correlates of SB across domains (i.e. occupational, leisure and transportation) in adults (mean ≥ 18 years old). Subgroup differences (sex, age, disease status, publication status and date, weekdays vs. weekend) were examined. Risk of bias was assessed, and a qualitative synthesis completed. PROSPERO: CRD42014009814ResultsSearching identified 22,779 articles; 257 were used in the analysis. Most studies used self‐reported SB and were cross‐sectional. The most studied domain of SB and correlate was leisure and intrapersonal, respectively. Consistent evidence found positive relationships between full‐time employment and higher transportation and lower leisure SB; higher income/socioeconomic status and greater transportation and occupation SB; living in more urban areas and greater sitting time and total SB; ownership of televisions and greater leisure SB; and, active workstations and lower occupational SB.ConclusionsThe review identifies the need for longitudinal studies, as well as further research on factors in the physical, social and policy environments. The review also recognizes the need to standardize methodology for collecting, defining and reporting SB and correlates.
