Human capital management and performance of community-based health planning and service (CHPS): a mediator analysis

Purpose This paper aims to examine the complexity of the relationship between human capital management (HCM) and the performance of community-based health planning and services (CHPS) from an emerging market perspective. It further explores the mediating role of community orientation; institutional intervention and capability of resources in the hypothesized relationship between HCM and the performance of CHPS. Design/methodology/approach Quantitative data was collected (through a survey) from 210 health volunteers using a systematic random sampling technique. A 95% response rate was realized and the data was analyzed using exploratory and confirmatory factor analysis and hierarchical multiple regression. Findings HCM has a direct relationship with the performance of the CHPS model. It also emerged that institutional intervention and capability of resources partially mediate the relationship between HCM and CHPS performance; while community orientation fully mediates the same relationship. Practical implications Capacity building for staff must be wired into the workings of the CHPS model to yield the maximum impact. This points to the need for training packages that focus on building both social and cultural competence for staff working among locals under the CHPS model. Effective planning is, thus, needed to ensure a seamless allocation of adequate resources to boost performance. Also, community engagement is critical to the success of the CHPS model as it could serve as a platform for awareness creation among locals. Originality/value This paper introduces community orientation, institutional intervention and capability of resources as mediating variables to investigate the hypothesized relationships. It offers a developing country insight into how HCM-related factors might be impacting the performance of community-based health programs.
Household ICT Utilization and Food Security Nexus in Nigeria

The study examines the nexus between household ICT utilization and food security in Nigeria, which supports goal 2 of the 2030 Sustainable Development Goals (SDGs) that aims to “end hunger, achieve food security, improved nutrition, and promote sustainable agriculture. ” The study employs the logit regression to wave 4 of Living Standard Measurement Integrated Survey on Agriculture (LSMS) data for the empirical analysis. Based on the analysis, the study finds that for male household, ICT utilization has a statistically significant and positive nexus with food security. In contrast, for the female households, an insignificant and, however, negative nexus is observed with food security in Nigeria. Furthermore, the findings show that for male household users, a 1 percent increase in male household ICT utilization spurs about 0.68 percent increase in food security in Nigeria. The findings imply that among the male and female household ICT users, the male household ICT utilization is significantly contributes to food security in Nigeria. The study recommends that relevant stakeholders take strategic measures to ensure that the potentials of household ICTs be fully maximized to contribute to food security in the nearest future as confirmed by studies in other regions.
Unbefriended, Uninvited: How End-of-Life Doulas Can Address Ethical and Procedural Gaps for Unrepresented Patients and Ensure Equal Access to the “Good Death”

In response to a global population with increasingly complex issues at the end of life, a movement in the U.S. has emerged incorporating doulas into end-of-life care. These end-of-life (EOL) doulas are not just focused on the quality of life, but also the quality of death. Like birth doulas, who provide support for pregnant patients and their families, EOL doulas help alleviate physical and mental discomfort in those who are dying. In this paper, we explore the role of EOL doulas in improving the care of unrepresented patients, who lack decision-making capacity and have no surrogates or documents to guide their healthcare decisions. We argue that EOL doulas may help this traditionally underserved population experience a “good death” by answering several ethical and procedural challenges. As quasi-independent, non-medical members of the healthcare team, they provide a balancing, advocating voice on behalf of the patient, and may also help reduce inappropriate treatment, delays in care, and the overburdening of the public guardianship system. As such, attention should be given to formally defining their place within the healthcare infrastructure. Ultimately, we contend that EOL doulas are key to ensuring optimal, ethical care for unrepresented patient populations.
Late-life immigrants’ place integration through occupation

ABSTRACT Immigrating and aging in a foreign environment, or aging out-of-place, is part of the late-life experience for a growing number of older adults. Examining how everyday occupations are part of late-life immigrants’ relationships to multiple places, cultures, and identities can expand upon scholarship addressing immigration in occupational science. This phenomenological study explored how Sinhalese late-life immigrants to Canada connect and engage with places through aging processes, centering the essentiality of daily occupations within such engagement. An interpretive paradigm and a hermeneutic phenomenological approach, informed by the work of van Manen (1984, 1997), guided the inquiry. Two phenomenological interviews were conducted with 10 Sinhalese late-life immigrants who immigrated to Canada within the last 10 years. Grounded in a transactional perspective, the theoretical concept of place integration was used as a lens through which to interpret how late-life immigrants establish relationships to the post-migration context through occupation. The essence of the aging out-of-place experience is elaborated through the presentation of four themes; 1) surrendering occupational roles and meaningful occupations, 2) feeling like an alien, 3) building a sense of continuity through occupation, and 4) integrating into place through occupational change. Sociopolitical forces and scarce interactions with the host society were unique place-based challenges in the aging out-of-place experience that threatened participants’ possibilities for action. Study findings highlight the centrality of occupation in the place integration process and illuminate the intersections between person, environment, and occupation.
A wideband vibration-based energy harvester

We present a new architecture for wideband vibration-based micro-power generators (MPGs). It replaces a linear oscillator with a piecewise-linear oscillator as the energy harvesting element of the MPG. A prototype of an electromagnetic MPG designed accordingly is analyzed analytically, numerically and experimentally. We find that the new architecture increases the bandwidth of the MPG during a frequency up-sweep, while maintaining the same bandwidth in a down-sweep. Closed-form expressions for the response of the new MPG as well as the up-sweep bandwidth are presented and validated experimentally. Simulations show that under random-frequency excitations, the new MPG collects more energy than the traditional MPG.
Solanum galapagense ‐derived purple tomato fruit color is conferred by novel alleles of the anthocyanin fruit and atroviolacium loci

One hypothesis for the origin of endemic species of tomato on the Galápagos islands postulates a hybridization of Solanum pimpinellifolium and S. habrochaites. S. galapagense accession LA1141 has purple fruit pigmentation which has previously been described in green-fruited wild tomatoes such as S. habrochaites. Characterization of LA1141 derived purple pigmentation provides a test of the hybridization hypothesis. Purple pigmentation was recovered in progenies derived from LA1141 and the anthocyanins malvidin 3(coumaroyl)rutinoside-5-glucoside, petunidin 3-(coumaroyl) rutinoside-5-glucoside, and petunidin 3-(caffeoyl)rutinoside-5-glucoside were abundant. Fruit color was evaluated in an introgression population and three quantitative trait loci (QTLs) were mapped and validated in subsequent populations. The loci atroviolacium on chromosome 7, Anthocyanin fruit on chromosome 10, and uniform ripening also on chromosome 10, underly these QTLs. Sequence analysis suggested that the LA1141 alleles of Aft and atv are unique relative to those previously described from S. chilense accession LA0458 and S. cheesmaniae accession LA0434, respectively. Phylogenetic analysis of the LA1141 Aft genomic sequence did not support a green-fruited origin and the locus clustered with members of the red-fruited tomato clade. The LA1141 allele of Aft is not the result of an ancient introgression and underlies a gain of anthocyanin pigmentation in the red-fruited clade. Highlight Anthocyanin fruit and atroviolacium confer purple pigmentation in Solanum galapagense LA1141 confirming a mechanism described for green-fruited tomatoes. LA1141 alleles cluster with red-fruited homologs suggesting an independent gain of pigmentation.
Analysis of floating body induced transient behaviors in partially depleted thin film SOI devices

Emphasis toward manufacturability of thin film SOI devices has prompted more attention on partially depleted devices. In this paper, drain current transients in partially depleted SOI devices due to floating-body effects are investigated quantitatively. A one-dimensional analytical model is developed to predict the transient effect and MEDICI simulation is performed to confirm the model. With the model, the amount of the turn-on current enhancement and the turn-off current suppression are calculated. The transient characteristics can be used in investigating the quality of the SOI materials by determining the carrier lifetime. The impact of the transient effect on the device parameter extraction is described.
Effects of Subsurface Drainage on Evapotranspiration for Corn and Soybean Crops in Southeastern North Dakota

AbstractA field experiment was conducted during the 2009 and 2010 growing seasons to determine the effect of subsurface drainage (SSD) on evapotranspiration (ET) and crop coefficients (Kc) for a farm field in the Red River Valley of North Dakota. The total area of the field was 44 ha, half of which had subsurface drainage installed in the fall of 2002 at an approximate depth of 1.1 m and a spacing of 18.3 m. Corn (Zea mays) was planted in 2009 and soybean (Glycine max) in 2010. Evapotranspiration rates were measured in both the SSD and surface drained [or undrained (UD)] by using the eddy covariance (EC) method. The changes in water table and soil moisture content were monitored continuously in both fields. The Kc for corn and soybean was developed by using the ET measured by the EC system, and the reference ET was estimated by using the American Society of Civil Engineers Environmental and Water Resources Institute alfalfa reference method. As expected, the use of SSD affected the ET in a seasonal patter.
Avalanche transport of energetic-ions in magnetic confinement plasmas: nonlinear multiple wave-number simulation

Large burst activity, identified as toroidal Alfvén eigenmode (TAE) avalanche, occurs frequently in neutral-beam heated plasmas in National Spherical Torus Experiment (NSTX). Based on the typical experimental observation of TAE avalanche on NSTX, a self-consistent nonlinear multiple wave-number (k ∥ ≃ n/R, where n toroidal mode-number and R major radius) simulation associated with TAE avalanches is performed using the experimental parameters and profiles before the occurrence of TAE avalanche as the M3D-K input. The wave–wave nonlinear coupling among different modes and the resonant interaction between different modes and energetic-ions during TAE avalanches are identified in the nonlinear multiple wave-number simulations. The resonance overlap during the TAE avalanche is clearly observed in the simulation. It is found that the effective wave–wave coupling and a sufficiently strong drive are two important ingredients for the onset of TAE avalanches. TAE avalanche is considered to be a strongly nonlinear process and it is always accompanied by the simultaneous rapid frequency-chirping and large amplitude bursting of multiple modes and significant energetic-ion losses. The experimental phenomenon is observed on NSTX and is qualitatively reproduced by the simulation results in this work. These findings indicate that the onset of avalanche is triggered by nonlinearity of the system, and are also conducive to understanding the underlying mechanism of avalanche transport of energetic particles in the future burning plasmas, such as International Thermonuclear Experiment Reactor.
Nonlinear amplifier effects on clipped-filtered multicarrier signals

The clipping-filtering method is a simple and frequently used in practice technique for reducing envelope fluctuations in multicarrier systems. When analysing systems that use clipping-filtering, very often a linear amplification is assumed. Meanwhile, a nonlinear amplifier inserts additional distortions into the clipped-filtered multicarrier signal. The cascade of the clipper-filter-nonlinear amplifier results in a nonlinear system with memory. The author studies both time-domain and frequency domain effects in this system. It is shown that while aggravating the total degradation in the system (almost for all values of the clipping ratio), the procedure of clipping-filtering provides a reduction of the out-of-band power emission after a nonlinear amplification. The author studies the structure of the clipped-filtered-amplified signal and proves that the signal constellation after this procedure is similar to that obtained after memoryless nonlinear processing, i.e. the observed signal is an attenuated version of the useful signal corrupted by Gaussian-like noise. Moreover, even under severe clipping and the working points of the amplifier close to the saturation (i.e. small values of the amplifier back-offs), Bussgang's theory can be approximately used for the prediction of distortions in the above scheme.
Pricing and Efficiency in a Decentralized Ride-Hailing Platform*

Asymmetric information about market participants’ valuations and costs plays a crucial role in the efficiency of a platform’s design. Using novel data from a ride-hailing platform called inDriver, I examine whether decentralizing the pricing mechanism improves market efficiency. Unlike its competitors, inDriver requires riders to offer a price for their requested trips, and allows drivers to either agree to the offer, ask for a higher price, or ignore the request. Under this mechanism, a rider with a high willingness to pay for a trip can offer a higher price to increase her chances of being matched. At the same time, under decentralized pricing riders might not truthfully reveal their valuations, which can result in lower average prices on the platform. To understand welfare implications of decentralized pricing for riders and drivers, I develop an equilibrium model of a decentralized ride-hailing market and estimate its parameters using user-level data on the universe of ride requests in a single city. I then use the obtained estimates to compare welfare under a decentralized mechanism to an alternative mechanism in which prices are chosen by the platform. I find that decentralized pricing significantly improves efficiency in the studied market. *I would like to thank Jean-François Houde, Alan Sorensen, and Ken Hendricks for their invaluable advice and guidance. I am indebted to Arsen Tomsky and the inDriver team for providing the data, answering my questions, and making this project possible.

NICE: Neural Image Commenting with Empathy

Emotion and empathy are examples of human qualities lacking in many human-machine interactions. The goal of our work is to generate engaging dialogue grounded in a usershared image with increased emotion and empathy while minimizing socially inappropriate or offensive outputs. We release the Neural Image Commenting with Empathy (NICE) dataset consisting of almost two million images and the corresponding human-generated comments, a set of human annotations, and baseline performance on a range of models. Instead of relying on manually labeled emotions, we also use automatically generated linguistic representations as a source of weakly supervised labels. Based on these annotations, we define two different tasks for the NICE dataset. Then, we provide a novel pre-training model Modeling Affect Generation for Image Comments (MAGIC) which aims to generate comments for images, conditioned on linguistic representations that capture style and affect, and to help generate more empathetic, emotional, engaging and socially appropriate comments. Using this model we achieve state-ofthe-art performance on one of our NICE tasks. The experiments show that the approach can generate more human-like and engaging image comments.
MKL1 is a prognostic biomarker correlated with immune infiltrates and chemosensitivity in breast cancer

Megakaryocytic leukemia 1 (MKL1) acts as a transcription factor in the regulation of the immune system and is associated with cancer biology. However, its function in the infiltrating immune cells in breast cancer has not been explored. Our study aimed to analyze the expression of MKL1 in The Cancer Genome Atlas (TCGA) breast cancer dataset. The aim of this study was to evaluate the correlations between MKL1 expression, infiltrating immune cells, and immune control genes. Enriched signaling pathways and drug sensitivity analyses were also performed. Our results indicate that high MKL1 expression could predict better survival in breast cancer patients. MKL1 expression was associated with the expression and function of different immune cells, including T cells, B cells, natural killer (NK) cells, macrophages, neutrophils and dendritic cells (DCs). The chromatin modifying enzymes, cellular senescence, epigenetic regulation of gene expression, estrogen-dependent gene expression, and chromosome maintenance were differentially enriched in MKL1 low expression phenotype. Patients in the high MKL1 expression group showed sensitivity to paclitaxel, while those in the low expression group showed potential sensitivity for cisplatin and docetaxel. In conclusion, MKL1 might act as a potential biomarker of prognostic value for immune infiltration and drug sensitivity in breast cancer.
Fooling Semantic Segmentation in One Step via Manipulating Nuisance Factors

Due to the inherent robustness of segmentation, traditional methods fail to attack it in a few steps. We demonstrate a simple and effective method that changes the nuisance factors to fool semantic segmentation models in a single step, even if the models have been adversarially trained for defense. By training conditional generative models with a designed adversarial loss, we can generate realistic adversarial attack by changing nuisance factors. Our method does not require neural network back-propagation, which is even faster than fast gradient sign method (FGSM). We validate our approach on the popular Cityscapes and ADE20K datasets, and demonstrate better attack success rate compared to the existed adversarial attacks for semantic segmentation including PGD, Houdini and DAG with over 100x speed-up, which is the ﬁrst method that can attack semantic segmentation models online.
A Dynamic Model for Single-Walled Carbon Nanotubes with Small Initial Curvature based on Nonlocal-Strain Gradient Theory

Since Carbon nanotubes (CNTS) was found in 1991, it is always the hot spot of the research [1]. CNTS has many excellent mechanics, electricity and chemical performance with high strength and toughness [2-3]. As CNTS have high length-diameter ratio, it can be used as an ideal composites of strengthening phase [4]. In order to excavate the huge potential application of CNTS, the mechanical properties of it have been studied extensively [5-6].
Towards Alleviating the Modeling Ambiguity of Unsupervised Monocular 3D Human Pose Estimation

In this work, we study the ambiguity problem in the task of unsupervised 3D human pose estimation from 2D counterpart. On one hand, without explicit annotation, the scale of 3D pose is difficult to be accurately captured (scale ambiguity). On the other hand, one 2D pose might correspond to multiple 3D gestures, where the lifting procedure is inherently ambiguous (pose ambiguity). Previous methods generally use temporal constraints (e.g., constant bone length and motion smoothness) to alleviate the above issues. However, these methods commonly enforce the outputs to fulfill multiple training objectives simultaneously, which often lead to sub-optimal results. In contrast to the majority of previous works, we propose to split the whole problem into two sub-tasks, i.e., optimizing 2D input poses via a scale estimation module and then mapping optimized 2D pose to 3D counterpart via a pose lifting module. Furthermore, two temporal constraints are proposed to alleviate the scale and pose ambiguity respectively. These two modules are optimized via a iterative training scheme with corresponding temporal constraints, which effectively reduce the learning difficulty and lead to better performance. Results on the Human3.6M dataset demonstrate that our approach improves upon the prior art by 23.1% and also outperforms several weakly supervised approaches that rely on 3D annotations.

Anti-Phospholipid Antibody Syndrome During Heart Disease The Aristide Le Dantec Hospital In Dakar

The occurrence of cardiac disease is multifactorial with two new risk factors, homocysteine and aPL [2, 3]. The cardiovascular system is one of the target organs of the aPLs. Indeed, aPLs are responsible for 40% of cases of coronary heart disease, valvular disease, intracavitary thrombosis, and 4-6% of cases of severe morbidity [2]. Among aPLs, anticardiolipids (aCLs) are an independent risk factor for myocardial infarction or cardiac arrest. Nevertheless, these cardiac events remain outside the criteria for defining APLS, which were updated in 2006 [1].
