Motivating Whistleblowers
Law-breaking activities within an organization bene?ting the ?rm at the expense of the general public are widespread but di¢ cult to uncover, making whistleblowing by employees desirable. We employ a novel laboratory experiment to investigate if and how monetary incentives and expectations of social approval or disapproval, and their interactions, a¤ect the decision to blow the whistle. Experimental results show that: i) ?nancial rewards signi?cantly increase the likelihood of whistleblowing and do not substantially crowd out non-monetary motivations activated by expectations of social judgment; and ii) the possibility of social judgment decreases (increases) whistleblowing when the public is unaware (aware) of the negative externalities generated by fraud, suggesting that whistleblowers are at least partly motivated by a desire for social approval. Our ?ndings suggest that whistleblowers on corporate fraud should be ?nancially rewarded and should be shielded from public/media scrutiny when the social cost of the illegal activity is not visible or salient to the public. We also ?nd evidence of an interesting relationship between political orientation and social judgment: while left-leaning subjects react to the possibility of receiving social approval or disapproval as expected, right-leaning people are una¤ected by it
Trial on use of a complete pelleted feed (Unipellet) in lactating ewes: metabolic profile results
A trial was carried out to examine the metabolic and productive effects of a complete pelleted
feed (Unipellet) in dairy ewes feeding. 24 Sardinian lactating ewes were divided in 3 groups
(A, B, C) and fed with: group A = pasture + pelleted concentrate; group B = alternatively
either pasture + Unipellet ad libitum or only Unipellet ad libitum; group C = pasture +
Unipellet ad libitum. The intake of concentrate was 756 g/d in the group A, whereas the
intake of Unipellet was 998 g/d in the group C and 858 g/d in the group B when the ewes
grazed and 2277 g/d when the Unipellet was the only fed. The milk yie1d of the 3 groups did
not differ significative1y (g/d 906 vs 1044 vs 975); the milk fat content was highest in the group
B (6.42% vs 7.08% vs 6.33%); the milk protein content was highest in the group A and lowest
in the group B (6.32% vs 5.55% vs 5.92%). The body weight increased more in the group B.
The metabolic profile showed that the Unipellet did not seem to have an adverse effect on the
alimentary canal, whereas the function of the liver appeared to be slight1y impaired
Intra Smart Grid Management Frameworks for Control and Energy Saving in Buildings
In the context of Smart Grids and Internet of Things (IoT) Systems, distributed monitoring and actuation through Wireless Sensor and Actuator Networks (WSANs) is fundamental to control the energy usage in buildings. Moreover, the realization of algorithms for the optimization of the energy consumption is of paramount importance. This paper presents a loosely coupled integration between a flexible management framework for WSANs, namely the IGMF (Intra-Grid Management Framework), and a Dynamic Energy Scheduler with local control on sensors and actuators, namely the ITESS (IoTLAB Energy Scheduling System). The integrated system allows the users to manage whole buildings applying Dynamic Energy Schedulers for different environments
Conflict violence reduction and pregnancy outcomes : a regression discontinuity design in Colombia
BACKGROUND: The relationship between exposure to conflict violence during pregnancy and the risks of miscarriage, stillbirth, and perinatal mortality has not been studied empirically using rigorous methods and appropriate data. We investigated the association between reduced exposure to conflict violence during pregnancy and the risks of adverse pregnancy outcomes in Colombia. METHODS AND FINDINGS: We adopted a regression discontinuity (RD) design using the July 20, 2015 cease-fire declared during the Colombian peace process as an exogenous discontinuous change in exposure to conflict events during pregnancy, comparing women with conception dates before and after the cease-fire date. We constructed the cohorts of all pregnant women in Colombia for each day between January 1, 2013 and December 31, 2017 using birth and death certificates. A total of 3,254,696 women were followed until the end of pregnancy. We measured conflict exposure as the total number of conflict events that occurred in the municipality where a pregnant woman lived during her pregnancy. We first assessed whether the cease-fire did induce a discontinuous fall in conflict exposure for women with conception dates after the cease-fire to then estimate the association of this reduced exposure with the risks of miscarriage, stillbirth, and perinatal mortality. We found that the July 20, 2015 cease-fire was associated with a reduction of the average number of conflict events (from 2.64 to 2.40) to which women were exposed during pregnancy in their municipalities of residence (mean differences −0.24; 95% confidence interval [CI] −0.35 to −0.13; p < 0.001). This association was greater in municipalities where Fuerzas Armadas Revolucionarias de Colombia (FARC) had a greater presence historically. The reduction in average exposure to conflict violence was, in turn, associated with a decrease of 9.53 stillbirths per 1,000 pregnancies (95% CI −16.13 to −2.93; p = 0.005) for municipalities with total number of FARC-related violent events above the 90th percentile of the distribution of FARC-related conflict events and a decrease of 7.57 stillbirths per 1,000 pregnancies (95% CI −13.14 to −2.00; p = 0.01) for municipalities with total number of FARC-related violent events above the 75th percentile of FARC-related events. For perinatal mortality, we found associated reductions of 10.69 (95% CI −18.32 to −3.05; p = 0.01) and 6.86 (95% CI −13.24 to −0.48; p = 0.04) deaths per 1,000 pregnancies for the 2 types of municipalities, respectively. We found no association with miscarriages. Formal tests support the validity of the key RD assumptions in our data, while a battery of sensitivity analyses and falsification tests confirm the robustness of our empirical results. The main limitations of the study are the retrospective nature of the information sources and the potential for conflict exposure misclassification. CONCLUSIONS: Our study offers evidence that reduced exposure to conflict violence during pregnancy is associated with important (previously unmeasured) benefits in terms of reducing the risk of stillbirth and perinatal deaths. The findings are consistent with such beneficial associations manifesting themselves mainly through reduced violence exposure during the early stages of pregnancy. Beyond the relevance of this evidence for other countries beset by chronic armed conflicts, our results suggest that the fledgling Colombian peace process may be already contributing to better population health
The Effect of the utilization of a high fibre pelleted feed on milk yield and composition in dairy sheep
Twenty Sardinian lactating ewes were divided in four groups (A, B, C, D) and fed with four diets,
obtained mixing a pelleted fibre integrator (PFI) and a normal pelleted concentrate (NPC) in different
proportions (NPC/PFI: A = 27/73; B = 42/58; C = 58/42; D = 73/27). The intake was 123,
122, 114 and 135 g of DM per kg of metabolic weight. The ewes were able to choose between the
two type of pellets. The chewing time per kg of DM decreased with the reduction of PFI content
in the diet. The ewes were always able to maintain a regular ruminal activity. There were no significant
differences in the milk yield, milk fat content, SCC and body weight variations, while the
milk protein content was higher in the group B
Association of chronic hepatitis C with major depressive disorders: irrespective of interferon-alpha therapy
Abstract
Background
Mood and anxiety symptoms in chronic hepatitis C (CHC) may be related to the patient awareness of the diagnosis and prognosis, to side effects induced by interferon (IFN)-alpha treatment, as well as to substance abuse. However, the observation of metabolic alterations in patients with CHC has led to hypothesize a direct effect of hepatitis C virus (HCV) on brain function. This study was aimed at elucidating whether CHC is associated with specific anxiety or mood disorders independently of confounding factors.
Methods
Patient cohort: consecutive patients, 135 with CHC and 76 with chronic hepatitis B (CHB). Exclusion criteria: previous treatment with IFN-alpha, co-infection with HCV and hepatitis B virus, infection with human immunodeficiency virus, drug or alcohol abuse, or malignancies. Controls: subjects without evidence of hepatitis randomly extracted from the database of a previous epidemiological study; they were divided into two groups of 540 (332 males) and 304 (220 males) as controls for patients with CHC and CHB, respectively. The psychiatric diagnosis was formulated by means of the Composite International Diagnostic Interview Simplified carried out by a physician according to DSM-IV criteria.
Results
A higher lifetime prevalence of major depressive disorder (MDD) was observed among CHC compared to CHB or controls. The risk of MDD was not statistically different between CHB and controls. Both the CHC and CHB groups showed a significantly higher frequency of panic disorder when compared to controls. No statistical differences were observed in the prevalence of general anxiety disorder and social phobia when CHC or CHB were compared to controls.
Conclusion
The present study provides the first evidence of an association between CHC and MDD, diagnosed on the basis of well-defined international criteria. This association is independent of treatment with IFN-alpha and is not influenced by substance or alcohol abuse. By contrast, anxiety disorders do not appear to be specifically associated with CHC
Combined Before-and-After Workplace Intervention to Promote Healthy Lifestyles in Healthcare Workers (STI-VI Study): Short-Term Assessment
Health care workers (HCWs) are prone to a heavy psycho-physical workload. Health promotion programs can help prevent the onset of chronic and work-related diseases. The aim of the STI-VI 'before-and-after' study, with assessments scheduled at 6 and 12 months, was to improve the lifestyle of HCWs with at least one cardiovascular risk factor. A tailored motivational counseling intervention, focusing on dietary habits and physical activity (PA) was administered to 167 HCWs (53 males; 114 females). BMI, waist circumference, blood pressure, and cholesterol, triglyceride, and blood glucose levels were measured before and after the intervention. The 6-month results (total sample and by gender) showed a marked effect on lifestyle: PA improved (+121.2 MET, p = 0.01), and diets became more similar to the Mediterranean model (+0.8, p < 0.001). BMI dropped (-0.2, p < 0.03), and waist circumference improved even more (-2.5 cm; p < 0.001). Other variables improved significantly: total and LDL cholesterol (-12.8 and -9.4 mg/dL, p < 0.001); systolic and diastolic blood pressure (-4.4 and -2.5 mmHg, p < 0.001); blood glucose (-1.5 mg/dL, p = 0.05); and triglycerides (significant only in women), (-8.7 mg/dL, p = 0.008); but HDL cholesterol levels dropped too. If consolidated at 12 months, these results indicate that our intervention can help HCWs maintain a healthy lifestyle and work ability
Morality traits for an ideal nurse manager: A multicentre cross‐sectional study
Aims
To investigate which morality traits are more important for nurses to determine positive opinions of their nurse manager.
Background
People selected morality more often than sociability and competence when forming a positive opinion towards an ideal or a newcomer manager.
Methods
A multicentre, cross-sectional study was carried out by administering two questionnaires to 775 nurses on the influence of morality, sociability and competence traits on their impression formation processes.
Results
Regarding nurses' perceptions about the morality, sociability and competence traits of an ideal nurse manager, the total score for morality was 20.0; for sociability, it was 14.2; and for competence, it was 19.6. For nurses' opinions about a new nurse manager, the total score of the morality section was 16.2, which was very similar to the total score of the competence section (mean = 16.1).
Conclusion
Morality positively influences nurses' initial impression of an ideal manager, and though it seems to be a necessary condition, it is not sufficient by itself to support the nursing staff's perception towards a new manager.
Implications for Nursing Management
Our findings could be useful in better understanding the role of morality in social perceptions and behavioural consequences of staff nurses towards their nurse manager
