Consequences of Unhappiness while Developing Software

The growing literature on affect among software developers mostly reports on the linkage between happiness, software quality, and developer productivity. Understanding the positive side of happiness – positive emotions and moods – is an attractive and important endeavor. Scholars in industrial and organizational psychology have suggested that also studying the negative side – unhappiness – could lead to cost-effective ways of enhancing working conditions, job performance, and to limiting the occurrence of psychological disorders. Our comprehension of the consequences of (un)happiness among developers is still too shallow, and is mainly expressed in terms of development productivity and software quality. In this paper, we attempt to uncover the experienced consequences of unhappiness among software developers. Using qualitative data analysis of the responses given by 181 questionnaire participants, we identified 49 consequences of unhappiness while doing software development. We found detrimental consequences on developers' mental well-being, the software development process, and the produced artifacts. Our classification scheme, available as open data, will spawn new happiness research opportunities of cause-effect type, and it can act as a guideline for practitioners for identifying damaging effects of unhappiness and for fostering happiness on the job.
Effects of supplementation with α-tocopherol, ascorbic acid, selenium, or their combination in linseed oil-enriched diets on the oxidative status in broilers

&NA; A trial was conducted to investigate whether, and if so to what extent, the combined supplementation of vitamin E, vitamin C, and selenium was superior to their sole supplementation concerning the oxidative stress induced by a high n‐3 dietary polyunsaturated fatty acids (PUFA) intake in broilers. Four hundred 21‐day‐old Ross 308 male broilers were allocated to 5 experimental groups fed the following linseed oil (5%)‐enriched finisher diets: Cont (no supplement), +E (200 IU vitamin E/kg feed), +C (250 mg vitamin C/kg feed), +Se (0.2 mg selenium/kg feed), or +ECSe (concentrations as in the sole supplementation, combined). Analyses of malondialdehyde (MDA), vitamin C, and &agr;‐ and &ggr;‐tocopherols in plasma, antioxidant capacity of water‐ (ACW) and lipid‐ (ACL) soluble compounds in serum, and glutathione peroxidase (GPx) and superoxide dismutase (SOD) activities in whole blood were performed. In breast muscle, analyses of MDA, &agr;‐ and &ggr;‐tocopherols, ACW, selenium, and fatty acid (FA) composition were carried out. Birds fed the combination of antioxidants showed reduced average daily gain (ADG) and average daily feed intake (ADFI) and, as +E, lower MDA and &ggr;‐tocopherol, together with raised &agr;‐ tocopherol levels in plasma and lower MDA and raised &agr;‐ tocopherol levels in breast muscle compared to the control. The combination of antioxidants in the +ECSe group raised GPx activity in whole blood compared to the control. In conclusion, results indicated that vitamin E is the most effective antioxidant to alleviate oxidative stress caused by high dietary PUFA and that the supplementation with additional vitamin C and selenium did not have clear synergistic effect.
Intergenerational violence in Burundi: Experienced childhood maltreatment increases the risk of abusive child rearing and intimate partner violence

Background Experiencing abuse during childhood affects the psychological well-being of individuals throughout their lives and may even influence their offspring by enhancing the likelihood of an intergenerational transmission of violence. Understanding the effects of childhood maltreatment on child-rearing practices and intimate partner violence might be of particular importance to overcome the consequences of violent conflicts in African societies. Objective Using Burundi as an example, we aimed to explore the associations between childhood maltreatment, intimate partner violence, perceived partner intimidation, gender and the probability of violently acting out against one's own children or romantic partner. Methods Amongst a sample of 141 men and 141 women in the capital of Burundi, we identified those who had biological children and those who lived or had lived in relationships. Using culturally appropriate instruments, we enquired about their exposure to childhood maltreatment and partner violence as well as their inclinations to act out violently. Results We found that childhood maltreatment and perceived partner intimidation were strong predictors for the perpetration of violence against children. Moreover, we found that women were more likely to use violence against children if they experienced partner violence and less likely to resort to violence if they felt intimidated. Men were more likely to perpetrate violence against their partner. Childhood maltreatment was again a strong predictor. The more women experienced partner violence, the more they fought back. Conclusions Childhood maltreatment is a strong predictor for domestic violence and has to be addressed to interrupt the cycle of violence in post-conflict countries.
Coverage maximization for a poisson field of drone cells

The use of drone base stations to provide wireless connectivity for ground terminals is becoming a promising part of future technologies. The design of such aerial networks is however different compared to cellular 2D networks, as antennas from the drones are looking down, and the channel model becomes height-dependent. In this paper, we study the effect of antenna patterns and height-dependent shadowing. We consider a random network topology to capture the effect of dynamic changes of the flying base stations. First we characterize the aggregate interference imposed by the co-channel neighboring drones. Then we derive the link coverage probability between a ground user and its associated drone base station. The result is used to obtain the optimum system parameters in terms of drones antenna beamwidth, density and altitude. We also derive the average LoS probability of the associated drone and show that it is a good approximation and simplification of the coverage probability in low altitudes up to 500 m according to the required signal-to-interference-plus-noise ratio (SINR).
Kalman filtering over fading channels with both transmission failure and signal fluctuation

This paper deals with the stability of the time-varying Kalman filter connected to the plant through fading channels subject to both transmission failure and signal fluctuation. Necessary and sufficient conditions on the network are derived for the stability of the mean error covariance matrix of a remote Kalman filter, and the corresponding network requirement is specified in terms of the unstable poles of the plant. Lower and upper bounds for the mean error covariance matrix are provided in the form of a modified Lyapunov iteration and a modified Riccati iteration. The results of this paper are illustrated by a numerical example.
Oxidative Stress Marker and Pregnancy Induced Hypertension

Background: Pregnancy induced hypertension (PIH) is a state of extremely increased oxidative stress. Hence, research and test of role and significance of oxidative stress in hypertensive disturbance in pregnancy is very important. Aim: Aims of this research were to determine a level of thiobarbituric acid reactive substance (TBARS) as oxidative stress marker in blood of pregnant woman with pregnancy induced hypertension and to analyze correlation of TBARS values with blood pressure values in pregnancy induced hypertensive pregnant women. Patients and methods: Research has been performed at the Clinic of Gynecology and Obstetrics, University Clinical Centre in the Republic of Srpska. It covered 100 pregnant women with hypertension and 100 healthy pregnant women of gestation period from 28 to 40 weeks. Level of TBARS is determined as an equivalent of malondialdehyde standard, in accordance with recommendations by producer (Oxi Select TBARS Analisa Kit). Results: Pregnancy induced hypertension is a state of extremely increased oxidative stress. All pregnant women experiencing hypertension had increased TBARS values in medium value interval over 20 µmol, 66%, whereas in group of healthy pregnant women, only 1% experienced increased TBARS value. Pregnant women with difficult preeclampsia (32%) had high TBARS values, over 40 µmol, and with mild PIH, only 4.9% pregnant women. Conclusion: Pregnant women with pregnancy induced hypertension have extremely increased degree of oxidative stress and lipid peroxidation. TBARS values are in positive correlation with blood pressure values, respectively the highest TBARS value were present in pregnant women with the highest blood pressure values.
Potential use of ceramic coating as a thermal insulation on cooled turbine hardware

An analysis was made to determine the potential benefits of using a ceramic thermal insulation coating of calcia-stabilized zirconia on cooled engine parts. The analysis was applied to turbine vanes of a high temperature and high pressure core engine and a moderate temperature and low pressure research engine. Measurements made during engine operation showed that the coating substantially reduced vane metal wall temperatures. Evaluation of the durability of the coating on turbine vanes and blades in a furnace and engine were encouraging.
Observer-Based Fuzzy Adaptive Output-Feedback Control of Stochastic Nonlinear Multiple Time-Delay Systems

This paper is concerned with the observer-based fuzzy output-feedback control for stochastic nonlinear multiple time-delay systems. On the basis of the consistent form of virtual input signals and increasing characteristics of the system upper bound functions, a variable splitting technique is employed to surmount the difficulty occurred in the nonlower-triangular form. In the controller design procedure, a state observer is first designed, and then an adaptive fuzzy output-feedback control method is presented by combining backstepping design together with fuzzy systems’ universal approximation capability. The proposed adaptive controller guarantees the semi-global boundedness of closed-loop system trajectories in terms of fourth-moment. Two simulation examples are displayed to demonstrate the feasibility of the suggested controller.
Early self-managed focal sensorimotor rehabilitative training enhances functional mobility and sensorimotor function in patients following total knee replacement: a controlled clinical trial

Objective: To assess the effects of early self-managed focal sensorimotor training compared to functional exercise training after total knee replacement on functional mobility and sensorimotor function. Design: A single-blind controlled clinical trial. Setting: University Hospital of Rion, Greece. Subjects: A total of 52 participants following total knee replacement. Outcome measures: The primary outcome was the Timed Up and Go Test and the secondary outcomes were balance, joint position error, the Knee Outcome Survey Activities of Daily Living Scale, and pain. Patients were assessed on three separate occasions (presurgery, 8 weeks post surgery, and 14 weeks post surgery). Intervention: Participants were randomized to either focal sensorimotor exercise training (experimental group) or functional exercise training (control group). Both groups received a 12-week home-based programme prescribed for 3–5 sessions/week (35–45 minutes). Results: Consistently greater improvements (F2,98 = 4.3 to 24.8; P < 0.05) in group mean scores favour the experimental group compared to the control group: Timed Up and Go (7.8 ± 2.9 seconds vs. 4.6 ± 2.6 seconds); balance (2.1 ± 0.9° vs. 0.7 ± 1.2°); joint position error (13.8 ± 7.3° vs. 6.2 ± 9.1°); Knee Outcome Survey Activities of Daily Living Scale (44.2 ± 11.3 vs. 26.1 ± 11.4); and pain (5.9 ± 1.3 cm vs. 4.6 ± 1.1 cm). Patterns of improvement for the experimental group over time were represented by a relative effect size range of 1.3–6.5. Conclusions: Overall, the magnitude of improvements in functional mobility and sensorimotor function endorses using focal sensorimotor training as an effective mode of rehabilitation following knee replacement.
Managing Anti-Fat Stigma in Primary Care: An Observational Study

ABSTRACT In many wealthy countries, fatness is stigmatized as a sign of personal failure. Health care interactions can enact fat-related stigmatization, which can worsen health outcomes. The present analysis highlights how stigmatizing discourses about fat bodies emerge in primary care appointments, and examines immediate conversational effects. Methods: Observational study in three primary care clinics in Canada, using conversation and discourse analytic methods on transcripts of 29 audio-recorded appointments with adults. Talk about weight and blood pressure are contrasted. Results: During measurement and review of measurements, clinicians routinely interpreted the blood pressure result but rarely interpreted weight. Patients of varied ages and body sizes often filled the interpretative vacuum, and focused on behaviors. Overall, neither patients nor clinicians challenged the stigmatizing discourses associated with fat bodies, but sometimes agreed that the “personal failure” frame associated with fatness does not apply to the particular patient. Physicians rarely raised other determinants of weight, but often did so when talking about blood pressure. Conclusions: Across most body types and ages, weight-related talk spurred stigma management from adult patients. Patients’ interpretations were consistent with accepting or avoidant strategies to manage stigma. The findings challenge clinicians and researchers to frame patients’ defensiveness or sensitivity as a predictable response to mitigate stigma, and consider how clinical care might be better structured to avoid stigmatization. Recognizing the range of determinants of weight with interpretation of weight may help, particularly if combined with other methods to de-stigmatize care. The results have implications for clinical weight management and behavior change support.
High-Order Sliding Mode Observer Based OER Control for PEM Fuel Cell Air-Feed System

This paper presents oxygen excess ratio (OER) control methods for proton exchange membrane fuel cell systems based on high-order sliding mode (HOSM) observer. The nonlinear and strong coupling characteristics make it difficult for the nonlinear uncertain systems to realize OER closed-loop feedback control. An improved HOSM observer is developed to observe the unmeasurable system states. Even under the interference of model parametric uncertainties, external disturbances, and measurement noises, the HOSM observer can still show fast convergence and good robustness. With the output error injection feature of improved HOSM algorithm, OER can be reconstructed in finite time. The proposed two stage sliding mode based on super twisting algorithm plus feedforward (TS_SM_STW+FF) controller and TS_SM_STW plus fuzzy feedforward (TS_SM_STW+Fuzzy_FF) controller are applied to regulate the estimated OER to track optimal value, respectively. The dynamic performance of OER with proposed methods is validated through the RT-LAB hardware-in-loop platform. The experimental results have shown the feasibility and effectiveness of proposed controllers as compared with conventional strategies.
Ground reaction force profiles after partial and pancarpal arthrodesis in dogs

Summary Objectives: To evaluate and compare long-term functional outcome after partial carpal arthrodesis and pancarpal arthrodesis in dogs using kinetic gait analysis. Methods: Fourteen dogs with 19 partial carpal or pancarpal arthrodeses were retrospectively examined and underwent force-plate gait analysis. Mean times since surgery were 29.4 and 24.4 months for pancarpal and partial carpal arthrodesis respectively. Vertical and braking-propulsive ground reaction force profiles were compared between treatment groups, and to those of normal dogs (control group) using Kruskal-Wallis one-way analysis of variance. Results: With the exception of time to vertical peak that occurred earlier in dogs with pancarpal than in dogs with partial carpal arthrodesis (p <0.01), there was no difference between the two treatment groups. Several parameters differed significantly between operated and healthy dogs (p <0.01): vertical impulses were significantly lower in both treatment groups, braking forces and impulses were also reduced after both techniques. Propulsive forces and impulses were only reduced in dogs with pancarpal arthrodesis. When comparing gait parameters of sound limbs of unilateral operated dogs to those of control dogs, braking forces and impulses (p <0.01; p <0.05) were significantly higher in the sound legs of unilateral operated dogs. Clinical Significance: Long-term outcome after partial carpal and pancarpal arthrodesis is good and comparable to each other. Propulsive action may be altered more in dogs with pancarpal arthrodesis.
Achieving Clinical Competencies Through Community-Based Clinical Experiences

BACKGROUND: Twenty-five percent of American adults experience a diagnosable psychiatric mental health (PMH) problem each year, and acute care medical-surgical nurses carry on average a five- to six-patient load per shift. Traditionally, U.S. PMH clinical experiences have occurred on inpatient units located within acute care hospitals or psychiatric hospital settings. However, many nursing programs are moving much of the PMH clinical experience to community-based settings. OBJECTIVES: This study aims to investigate how prelicensure undergraduate baccalaureate (BSN) student nurses and their faculty perceive students’ ability to achieve learning outcomes in community-based PMH clinical settings. This study’s research questions include the following: (a) What are student nurses’ perceptions of their abilities to achieve learning outcomes in community-based PMH clinical settings? (b) What are faculty’s perceptions of the students’ abilities to achieve learning outcomes in community-based PMH clinical settings? (c) What are student nurses’ perceptions of their abilities to transfer knowledge gained in their community-based PMH clinical experiences to other health care settings? DESIGN: Qualitative descriptive study with data collected through semistructured interviews, questionnaires, focus groups, and campus and clinical site visits. RESULTS: Three student themes emerged from the data: meeting the challenges of developing PMH nursing skills, sharing multiple experiences of feeling competent, and empowering all nurses through PMH nursing skills. Three themes also emerged from the faculty data: seizing the day(s), sharing competency, and broadly empowering nursing students. CONCLUSIONS: Baccalaureate students are able to achieve PMH clinical competencies through the use of community-based experiences and to transfer PMH competencies to other clinical settings.
Language Deficits as a Preclinical Window into Parkinson’s Disease: Evidence from Asymptomatic Parkin and Dardarin Mutation Carriers

Abstract Objectives: The worldwide spread of Parkinson’s disease (PD) calls for sensitive and specific measures enabling its early (or, ideally, preclinical) detection. Here, we use language measures revealing deficits in PD to explore whether similar disturbances are present in asymptomatic individuals at risk for the disease. Methods: We administered executive, semantic, verb-production, and syntactic tasks to sporadic PD patients, genetic PD patients with PARK2 (parkin) or LRRK2 (dardarin) mutation, asymptomatic first-degree relatives of the latter with similar mutations, and socio-demographically matched controls. Moreover, to detect sui generis language disturbances, we ran analysis of covariance tests using executive functions as covariate. Results: The two clinical groups showed impairments in all measures, most of which survived covariation with executive functions. However, the key finding concerned asymptomatic mutation carriers. While these subjects showed intact executive, semantic, and action-verb production skills, they evinced deficits in a syntactic test with minimal working memory load. Conclusions: We propose that this sui generis disturbance may constitute a prodromal sign anticipating eventual development of PD. Moreover, our results suggest that mutations on specific genes (PARK2 and LRRK2) compromising basal ganglia functioning may be subtly related to language-processing mechanisms.

The Multivehicle Stereo Event Camera Dataset: An Event Camera Dataset for 3D Perception

Event-based cameras are a new passive sensing modality with a number of benefits over traditional cameras, including extremely low latency, asynchronous data acquisition, high dynamic range, and very low power consumption. There has been a lot of recent interest and development in applying algorithms to use the events to perform a variety of three-dimensional perception tasks, such as feature tracking, visual odometry, and stereo depth estimation. However, there currently lacks the wealth of labeled data that exists for traditional cameras to be used for both testing and development. In this letter, we present a large dataset with a synchronized stereo pair event based camera system, carried on a handheld rig, flown by a hexacopter, driven on top of a car, and mounted on a motorcycle, in a variety of different illumination levels and environments. From each camera, we provide the event stream, grayscale images, and inertial measurement unit (IMU) readings. In addition, we utilize a combination of IMU, a rigidly mounted lidar system, indoor and outdoor motion capture, and GPS to provide accurate pose and depth images for each camera at up to 100 Hz. For comparison, we also provide synchronized grayscale images and IMU readings from a frame-based stereo camera system.
Emotion detection using noninvasive low cost sensors

Emotion recognition from biometrics is relevant to a wide range of application domains, including healthcare. Existing approaches usually adopt multi-electrodes sensors that could be expensive or uncomfortable to be used in real-life situations. In this study, we investigate whether we can reliably recognize high vs. low emotional valence and arousal by relying on noninvasive low cost EEG, EMG, and GSR sensors. We report the results of an empirical study involving 19 subjects. We achieve state-of-the-art classification performance for both valence and arousal even in a cross-subject classification setting, which eliminates the need for individual training and tuning of classification models.
