The perceptions of commune health workers about an education strategy received for counselling fathers about infant and breastfeeding involvement

Objective To evaluate the perceptions of healthcare workers in Vietnam about the efficacy of a continuing education strategy about father involvement and breastfeeding counselling. Design One group, post-test only, quasi-experimental design Method A questionnaire based on Social Cognitive Theory (SCT; Bandura, 2004) was disseminated to participants (N=28). This questionnaire measured self-efficacy, outcome expectations, socio-structural factors, goal setting and behaviour. Multiple regressions were analyzed predicting participants’ practice of client focused father involvement consulting. Results Bivariate correlations demonstrated the anticipated patterns of association between SCT-based constructs. Multiple regression analysis indicated that outcome expectations and barriers were significant predictors of client focused father involvement consulting. Conclusions Participants reported that the education increased their self-efficacy, outcome expectations and client focused father involvement consulting behaviour. Future education should be accessible, increase counselling confidence and address beliefs about the outcomes and challenges of father involvement consulting.

The involvement of nitric oxide in bovine follicular development and ovulation

Comprendre les événements paracriniens qui régulent la fertilité chez la vache est nécessaire non seulement en raison de l'importance agricole de cette espèce, mais aussi pour son utilisation potentielle comme modèle chez l’humain. L'oxyde nitrique (NO), un gaz de radicaux libres, a été impliqué dans la croissance folliculaire et l'ovulation chez les rongeurs et d'autres espèces, mais chez la vache c’est une énigme fascinante : le NO est produit par les cellules de la granulosa bovine et est régulé par la FSH, mais la présence et le profil d'expression des enzymes responsables de la synthèse de NO (NOS) dans les cellules de la granulosa tout au long de la croissance folliculaire ne sont pas claires. Les objectifs de cette thèse sont: (1) élucider le mécanisme de contrôle des NOS et les conséquences de la production d'oxyde nitrique pour le fonctionnement des cellules de la granulosa au cours du développement folliculaire chez la vache et (2) déterminer la régulation des NOS pendant la cascade ovulatoire induite par LH chez les cellules de la granulosa bovine et si l'activité des NOS pour l’expression des gènes critiques dans la cascade ovulatoire chez cette espèce. Les résultats sont séparés en 2 articles. Dans le premier article, la régulation de NOS2 dans les cellules de la granulosa bovine a été explorée. L'abondance des ARNm codant pour NOS2 a été stimulée par la FSH et l’IGF1 en augmentant l’estradiol, et un blocage de l'action de l’estradiol a conséquemment réduit les niveaux d'ARNm codant pour NOS2. De plus, l'inhibition de l'activité des NOS a augmenté l'apoptose dans les cellules de la granulosa in vitro. Dans le second article, il a été démontré que le pic de LH induit une activation des NOS dans les cellules de la granulosa, et que l'activité de NOS induit la production de NO, ce qui est essentiel pour l’expression des gènes critiques dans la cascade ovulatoire induite par LH comme EREG/AREG/PTGS2. Ensemble, les résultats présentés dans ces 2 articles suggèrent que les niveaux physiologiques d'activité des NOS peuvent contribuer à la croissance et la survie des cellules de la granulosa et indiquent également que NO peut être essentiel pour l'ovulation chez les bovins.

Lower Bounds for Achieving Synchronous Early Stopping Consensus with Orderly Crash Failures

In this paper, we discuss the consensus problem for synchronous distributed systems with orderly crash failures. For a synchronous distributed system of n processes with up to t crash failures and f failures actually occur, first, we present a bivalency argument proof to solve the open problem of proving the lower bound, min (t + 1, f + 2) rounds, for early-stopping synchronous consensus with orderly crash failures, where t < n - 1. Then, we extend the system model with orderly crash failures to a new model in which a process is allowed to send multiple messages to the same destination process in a round and the failing processes still respect the order specified by the protocol in sending messages. For this new model, we present a uniform consensus protocol, in which all non-faulty processes always decide and stop immediately by the end of f + 1 rounds. We prove that the lower bound of early stopping protocols for both consensus and uniform consensus are f + 1 rounds under the new model, and our proposed protocol is optimal.

16/6-idiotype expressing antibodies induce brain inflammation and cognitive impairment in mice: the mosaic of central nervous system involvement in lupus

Background: The 16/6-idiotype (16/6-Id) of the human anti-DNA antibody was found to induce experimental lupus in naive mice, manifested by production of autoantibodies, leukopenia and elevated inflammatory markers, as well as kidney and brain involvement. We assessed behavior and brain pathology of naive mice injected intracerebra-ventricularly (ICV) with the 16/6-Id antibody. Methods: C3H female mice were injected ICV to the right hemisphere with the human 16/6-Id antibody or commercial human IgG antibodies (control). The mice were tested for depression by the forced swimming test (FST), locomotor and explorative activity by the staircase test, and cognitive functions were examined by the novel object recognition and Y-maze tests. Brain slices were stained for inflammatory processes. Results: 16/6-Id injected mice were cognitively impaired as shown by significant differences in the preference for a new object in the novel object recognition test compared to controls (P = 0.012). Similarly, the preference for spatial novelty in the Y-maze test was significantly higher in the control group compared to the 16/6-Id-injected mice (42% vs. 9%, respectively, P = 0.065). Depression-like behavior and locomotor activity were not significantly different between the16/6-Id-injected and the control mice. Immunohistochemistry analysis revealed an increase in astrocytes and microglial activation in the hippocampus and amygdala, in the 16/6-Id injected group compared to the control. Conclusions: Passive transfer of 16/6-Id antibodies directly into mice brain resulted in cognitive impairments and histological evidence for brain inflammation. These findings shed additional light on the diverse mosaic pathophysiology of neuropsychiatric lupus.

Involvement in environmental causes, does the joint effect between subjective income and the performance of the country matter?

Previous research has shown that richer people are more likely to engage in an environmentalcause. We extend it by considering the joint effect between subjective income and a set of macroeconomicvariables. For doing so, we employ the fifth wave of the World Values Survey (WVS).This study provides clear evidence that even when both factors matter, people´s attitudes cruciallydepend on the interaction effect. Hence, those measures that affect the characteristics of thecountry would also change the disposition to be involved.

Economic shocks and crime: evidence from the crash of ponzi schemes

In November 2008, Colombian authorities dismantled a network of Ponzi schemes, making hundreds of thousands of investors lose tens of millions of dollars throughout the country. Using original data on the geographical incidence of the Ponzi schemes, this paper estimates the impact of their break down on crime. We find that the crash of Ponzi schemes differentially exacerbated crime in affected districts. Confirming the intuition of the standard economic model of crime, this effect is only present in places with relatively weak judicial and law enforcement institutions, and with little access to consumption smoothing mechanisms such as microcredit. In addition, we show that, with the exception of economically-motivated felonies such as robbery, violent crime is not affected by the negative shock.
