Will They Stay or Leave? Interplay of Organizational Learning Culture and Workplace Mindfulness on Job Satisfaction and Turnover Intentions

Due to the ever-increasing standards required of administrative workloads, service efficiency, and quality, the turnover intentions of public servants in Taiwan have gradually increased over time. This study investigated the critical factors that reduce the turnover intentions of civil servants. The article is intended to offer a theoretical understanding of an organizational learning culture (OLC) and workplace mindfulness. We analyzed data from 331 public servants. Structural equation modeling and the bootstrapping method were used to verify the hypotheses. The results demonstrated that an OLC and workplace mindfulness are positively associated with job satisfaction and negatively associated with turnover intentions. Job satisfaction plays a mediating role between an OLC and turnover intentions and between workplace mindfulness and turnover intentions. This article offers a theoretical inquiry and a practical understanding of strengthening the workplace atmosphere by offering employees a sense of well-being and sustainable career development.
Mathematical Modeling of Ion Quantum Tunneling Reveals Novel Properties of Voltage-Gated Channels and Quantum Aspects of Their Pathophysiology in Excitability-Related Disorders

Voltage-gated channels are crucial in action potential initiation and propagation and there are many diseases and disorders related to them. Additionally, the classical mechanics are the main mechanics used to describe the function of the voltage-gated channels and their related abnormalities. However, the quantum mechanics should be considered to unravel new aspects in the voltage-gated channels and resolve the problems and challenges that classical mechanics cannot solve. In the present study, the aim is to mathematically show that quantum mechanics can exhibit a powerful tendency to unveil novel electrical features in voltage-gated channels and be used as a promising tool to solve the problems and challenges in the pathophysiology of excitability-related diseases. The model of quantum tunneling of ions through the intracellular hydrophobic gate is used to evaluate the influence of membrane potential and gating free energy on the tunneling probability, single channel conductance, and quantum membrane conductance. This evaluation is mainly based on graphing the mathematical relationships between these variables. The obtained mathematical graphs showed that ions can achieve significant quantum membrane conductance, which can affect the resting membrane potential and the excitability of cells. In the present work, quantum mechanics reveals original electrical properties associated with voltage-gated channels and introduces new insights and implications into the pathophysiology of excitability- related disorders. In addition, the present work sets a mathematical and theoretical framework that can be utilized to conduct experimental studies in order to explore the quantum aspects of voltage-gated channels and the quantum bioelectrical property of biological membranes.
Evaluasi Performa Karkas Kelinci Lokal dan New Zealand White Jantan pada Berat Potong yang Berbeda

This study investigated the performance of Local and New Zealand White buck carcass at different weights. A factorial completely randomized design was applied, with rabbit breeds (local and New Zealand White) and weight category (<2 kg and >2 kg) as factors. 60 bucks were used divided into 15 bucks per group. Carcass weight, meat weight, bone weight, carcass percentage, meat percentage, bone percentage, meat bone ratio (MBR) were observed. Correlation between slaughter and carcass weight with carcass weight, meat weight, bone weight carcass percentage, meat percentage, bone percentage and MBR also observed in this study. Results showed that the differences in breeds and slaughtering weight gave significant differences in carcass, meat, and bone weight (P<0.05). Slaughtering weight was positively correlated with carcass weight (R2=0.955; P<0.01). Breed and slaughtering weight category differences did not significantly affect carcass percentage, where local rabbit carcass was 53.04%, while New Zealand White was 51.66%. There was no significant difference between MBR in the two groups with weight >2 kg. New Zealand White rabbits in <2 kg weight categories produced the lowest MBR by 2.17 (P<0.05). Significant interaction (P<0.01) between different breed and weight categories was reported on carcass weight, carcass percentage, and meat weight. In conclusion, there are no differences in carcass percentage and MBR ratio between two rabbit breeds with <2 kg weight categories. New Zealand White rabbits should be slaughtered at >2 kg weight categories due to the lower MBR ratio on <2 kg weight categories. The current study reported that there was an interaction between different breed and weight categories on carcass performance.
Optimization and Simulation of Dynamic Performance of Production–Inventory Systems with Multivariable Controls

The production–inventory system is a problem of multivariable input and multivariant output in mathematics. Selecting the best system control parameters is a crucial managerial decision to achieve and dynamically maintain an optimal performance in terms of balancing the order rate and stock level under dynamic influence of many factors affecting the system operations. The dynamic performance of the popular APIOBPCS model and the newly modified 2APIOBPCS model for optimal control of production–inventory systems is examined in the study. This examination is based on the leveled ground with a new simulation scheme that incorporates a designated multi-objective particle swarm optimization (MOPSO) algorithm into the simulation, which enables the optimal set of system control parameters to be selected for achieving the situational best possible performance of the production–inventory system under study. The dynamic performance is measured by the variance ratio between the order rate and the sales rate related to the bullwhip effect, and the integral of absolute error related to the inventory responsiveness in response to a random customer demand. Our simulation indicates that the 2APIOBPCS model performed better than or at least no worse than, and more robust than the APIOBPCS model under different conditions.
Effect of Bacillus cereus IP 5832 and coumarin in the diet on the general state of the broilers

Currently, there is an interest in complex biological preparations based on probiotic strains and plant extracts. Probiotic preparations, together with plant extracts, are natural growth stimulants and can become a promising replacement for antibiotic growth stimulants in poultry farming, the latter stimulate the production of endogenous enzymes, improving the digestibility and absorption of nutrients in feed. Technological prospects for the probiotics and plant extracts practical joint use in poultry farming touch upon a wide range of problems related to the correction of intestinal biocenosis, hormonal and enzymatic systems, stimulation of immunity, prevention and treatment of dysbacteriosis. The purpose of this study is to assess the effect of the complex introduction of the probiotic strain Bacillus cereus and a coumarin derivative in the diet of broiler chickens on hematological parameters. In the studied broiler chickens, changes in hematological and biochemical parameters are noted in connection with the processes of their growth and development. All parameters in the blood are accompanied by changes, which indicates an intense metabolic rate, an additional load in the metabolism that requires the participation of protective blood elements.
Modified Ankle Joint Neuromechanics during One-Legged Heel Raise Test after an Achilles Rupture and Its Associations with Jumping

This study had two purposes. The first purpose of the study was to compare the electromyographic(EMG) and dynamic characteristics in injured and non-injured legs during the one-legged heel-raise test after a unilateral Achilles repair. The second purpose was to determine the correlations between the EMG results and the dynamic characteristics and between the characteristics in the eccentric phase and jumping distance. Twenty-six participants who underwent an Achilles repair between 4 and 12 months prior to the measurement were recruited to perform the following bilateral tests: (1) one-legged heel-raise test with measurements of muscle activation, kinematics, and kinetics and (2) one-legged forward jumping. During the heel-raise exercise, there were increases of the EMG amplitudes in the soleus and tibialis anterior muscles, lower ankle joint angle and angular velocity, lower normalized ground reaction force, and mechanical work in the repaired legs in comparison to the non-injured legs. The EMG results of the medial gastrocnemius and soleus muscles correlated with the dynamic results (rs = 0.467 and −0.537). Furthermore, the dynamic data in the eccentric phase were correlated with the jumping performance (rs = 0.575 and −0.471). It is concluded the soleus muscle undergoes neuromechanical changes, including changes in EMG and dynamic characteristics, and changes affecting jumping performance.
Evaluation of nuclear medicine planar images based on partial volume effects and recovery coefficients at different activity levels of radionuclides and matrix sizes

The partial volume effect evaluations had been effectively used as method for the evaluation of SPECT images in nuclear medicine. The study focused on the use of partial volume effect method and the evaluation of recovery coefficient in the 2D planar images in nuclear medicine. The planar images were obtained by using a modified Jaszczak phantom that contains radionuclide volume of differents diameter sizes and three activity levels. The planar images were also taken at three different matrix sizes of gamma camera set up at 128 x 128, 256 x 256 and 512 x 512. The results showed that the contrast values increased exponentially at larger diameter sizes of radionuclide. The contrast also significantly increased when higher matrix sizes were used. The recovery coefficient evaluation of the planar images were singnificantly decreased when larger matrix sizes were used. There were no significant differences between the recovery coefficients between planar images obtained with and without background counts. The overall results indicated the suitability of using the partical volume efffect method to evaluate the planar images of nuclear medicine.
A-Judo: An Innovative Intervention Programme to Prevent Bullying Based on Self-Determination Theory—A Pilot Study

This study aimed to evaluate the effectiveness of an intervention entitled A-Judo Programme for the reduction in bullying and improvement of prosocial behaviour at school, based on the theory of self-determination (SDT). Physical education teachers (PETs) received 20 h of specific training, implementing the programme thereafter in their classes in a total of 10 sessions of 50 min each (two sessions per week over 5 weeks). Variables such as teacher’s teaching style, basic psychological needs (BPNs), self-determined motivation, tolerance and respect, moral identity, harassment and victimisation were studied. Seventy-nine students (11.13 ± 0.52 y) of both sexes (40 girls and 39 boys) participated in the study and were divided into an intervention and a control group (which received no training). The results showed significant changes with moderate to high effect sizes in BPN, motivation, tolerance–respect, moral identity and bullying. These research findings improve the body of knowledge of the applications offered by SDT and its usefulness for improving anti-bullying programmes through PET training.
Risky urban futures

It was spring 2016. Mzunguko wa pesa umekatika, ‘money’s stopped circulating’, was an expression on everybody’s lips. It put the current hardship of life in Dar es Salaam into words and, reiterated in daily conversations, it took the form of a contemporary proverb. Cash flow was low. Maisha magumu, ‘life’s hard’. The austerity narrative had many expressions. Informal greetings would be met with a shrug and a casual tunapambana na hali hii, ‘we’re struggling with this situation’. After all, life went on but vyuma vimekaza, ‘it’s tight’. During a meeting in Dodoma, Tanzania’s capital, the country’s president, John Pombe Magufuli, coined a new phrase that soon went viral, both in approval and ridicule: watu wanasema vyuma wimekaza – weka grisi, ‘people say the steel is tight – use grease to lubricate it’. The meaning risks being lost in translation, but the message was clear. It called for patience, endurance and self-reliance in the face of austerity. More than half a century after independence, the phrase seemed to echo the moral legacy of baba wa taifa, the father of the nation and the mastermind behind a prominent strand of African socialism, Ujamaa (a Swahili word that translates as ‘familyhood’ or ‘extended family’): the late Julius Kambarage Nyerere. While Nyerere’s idea of self-reliance, kujitegemea, was based on agrarian socialism (Nyerere, 1967), the concept translated well into an increasingly urban Tanzania. Money might be short, and formal work out of reach but, as a boda boda (motorcycle taxi) driver argued while waiting for
Electron mobility in monolayer WS2 encapsulated in hexagonal boron-nitride

We report electron transport measurements in dual-gated monolayer WS2 encapsulated in hexagonal boron-nitride. Using gated Ohmic contacts that operate from room temperature down to 1.5 K, we measure the intrinsic conductivity and carrier density as a function of temperature and gate bias. Intrinsic electron mobilities of 100 cm2/(V s) at room temperature and 2000 cm2/(V s) at 1.5 K are achieved. The mobility shows a strong temperature dependence at high temperatures, consistent with phonon scattering dominated carrier transport. At low temperature, the mobility saturates due to impurity and long-range Coulomb scattering. First-principles calculations of phonon scattering in monolayer WS2 are in good agreement with the experimental results, showing we approach the intrinsic limit of transport in these two-dimensional layers.
Improving the Representation of Subtropical Boundary Layer Clouds in the NASA GEOS Model with the Eddy-Diffusivity/Mass-Flux Parameterization

A systematic underestimation of subtropical planetary boundary layer (PBL) stratocumulus clouds by the GEOS model has been significantly improved by a new eddy-diffusivity/mass-flux (EDMF) parameterization. The EDMF parameterization represents the subgrid-scale transport in the dry and moist parts of the PBL in a unified manner and it combines an adjusted eddy-diffusivity PBL scheme from GEOS with a stochastic multiplume mass-flux model. The new EDMF version of the GEOS model is first compared against the CONTROL version in a single-column model (SCM) framework for two benchmark cases representing subtropical stratocumulus and shallow cumulus clouds, and validated against large-eddy simulations. Global simulations are performed and compared against observations and reanalysis data. The results show that the EDMF version of the GEOS model produces more realistic subtropical PBL clouds. The EDMF improvements first detected in the SCM framework translate into similar improvements of the global GEOS model.
Generation of cancellable locality sampled codes from facial images

Face is arguably the most common biometric trait that has been extensively utilised and thoroughly studied. Since this unimodal feature visually represents the identity of an individual, preserving the security of face ‐ based authentication models is a prime concern. This work proposes a framework for generating cancellable templates from raw facial images. Our scheme is essentially based upon the notion of locality sensitive hashing (LSH), specifically on its locality sampled code (LSC) realisation. Facial features are initially extracted using the binarized statistical image features (BSIF) descriptor. These binary features are subsequently hashed using the random bit sampling mechanism of LSC. Finally, these local hashes are permanently stored in a non ‐ invertible manner. We have empirically analysed the security requirements of unlinkability, non ‐ invertibility, and revocability in our model. We have also validated our work over the benchmark AR, ORL, Yale, and CASIA ‐ Facev5 databases under multiple scenarios. Among all the resulting cases, the best performance of our model was noted at a minimum EER of 2.69%, 4.45%, 1.2%, and 2.66% for the four data sets, respectively.
Effect of Low temperature treatment on dormancy release of Sedum aizoon L.

The dormant Sedum aizoon L.seedlings were treated with different days(1d, 3d, 5d and 7d) of low temperature (5°C), and restored to grow for 40d (25°C). The growth indexes, photosynthetic characteristics and carbohydrate metabolism indexes were measured to compare the dormancy relieving effects of the seedlings. The results showed that Sedum aizoon L. was physiologic dormancy, and the effect was the best when it was treated at 5°C for 5 days, and the dormancy was completely relieved.
Epidemiological Profile of In-Hospital Deaths in a Tertiary Health Care Centre: A 3-Year Retrospective Study in Western Maharashtra

The knowledge of specific contributors to mortality is crucial for the improvement of health of the community. Globally, medical certificate of cause of death is used for gathering epidemiological statistics. Our study examines the mortality pattern with sociodemographic characteristics of in-hospital deaths, which occurred at a tertiary health care center in Maharashtra. This study is a descriptive retrospective study in which 1,000 medical certification of cause of death forms (n = 1000) filled at a tertiary care hospital between Aug 2016 and Aug 2019 were analyzed. Total 64.5% of cases were males and 35.5% were females. About 42% were elderly (60–80 years). About 23% of the deaths were due to “diseases of the circulatory system. ” The highest number of cases died within the first 10 days of admission. The “diseases of circulatory system” was the commonest group causing deaths in “brief” hospital stay ((<10 days), “diseases of digestive system” in “short” (10 days–1 month), “neoplasia” in “long” (1–3 months), and “diseases of nervous system” in “prolong” hospital stay (>3 months). The mortality rate among males was more than twice of females and maximum deaths were observed in the geriatric age group. The chief causes of mortality overall and among both males and females individually were the diseases of the circulatory system among which, the cerebrovascular diseases accounted for highest number of cases. Overall demographic data were comparable to observations from various national and international studies. Cause-specific mortality statistics are routinely required by policy makers, researchers, and other professionals for decision-making for resource allocation, monitoring of health indicators, and identifying priorities for health initiatives. Availability of data remains limited and inadequate in many countries. Studies on in-hospital deaths are needed to identify mortality indicators in different regions and channel public health initiatives in the right direction. Chourasia S, Dhaka S, Rautji R, et al.

Integrative molecular characterization of pediatric spinal ependymoma: the UK Children’s Cancer and Leukaemia Group study

Abstract Background Pediatric spinal ependymomas (SP-EPNs) are rare primary central nervous system tumors with heterogeneous clinical course. Considering that ependymomas in children are biologically distinct from their adult counterparts, this study aimed to define the molecular landscape of SP-EPNs in children. Methods In this retrospective study, we have collected tumor samples from 27 SP-EPN patients younger than 18 years and carried out the histological review, DNA methylation, and gene expression profiling. Results Unsupervised analyses with methylation profiles revealed 2 subgroups where all grade I tumors (n = 11) were in Group 1, but the grade II/III tumors split into 2 groups (n = 7 in Group 1 and n = 9 in Group 2). The Heidelberg classifier assigned Group 1 tumors as spinal myxopapillary ependymomas (SP-MPEs), 5 Group 2 tumors as SP-EPNs, and failed to classify 4 Group 2 tumors. Copy numbers derived from DNA methylation arrays revealed subgroup-specific genetic alterations and showed that SP-EPN tumors lack MYCN amplification. Gene expression profiling revealed distinct transcriptomic signatures, including overexpression of genes involved in oxidative phosphorylation in SP-MPEs that were validated by Western blot analysis. We discovered widespread decreases in DNA methylation at enhancer regions that are associated with the expression of oncogenic signaling pathways in SP-MPEs. Furthermore, transcription factor motifs for master regulators, including HNF1B, PAX3, and ZIC3, were significantly overrepresented in probes specific to distal regulatory regions in SP-MPEs. Conclusion Our findings show substantial heterogeneity in pediatric SP-EPN and uncover novel enhancers and transcriptional pathways specific to the SP-MPE subgroup, providing a foundation for future therapeutic strategies.
Preserving Human Perspectives in Cultural Heritage Acoustics: Distance Cues and Proxemics in Aural Heritage Fieldwork

We examine the praxis implications of our working definition of aural heritage: spatial acoustics as physically experienced by humans in cultural contexts; aligned with the aims of anthropological archaeology (the study of human life from materials). Here we report on human-centered acoustical data collection strategies from our project “Digital Preservation and Access to Aural Heritage via a Scalable, Extensible Method,” supported by the National Endowment for the Humanities (NEH) in the USA. The documentation and accurate translation of human sensory perspectives is fundamental to the ecological validity of cultural heritage fieldwork and the preservation of heritage acoustics. Auditory distance cues, which enable and constrain sonic communication, relate to proxemics, contextualized understandings of distance relationships that are fundamental to human social interactions. We propose that source–receiver locations in aural heritage measurements should be selected to represent a comprehensive range of proxemics according to site-contextualized spatial-use scenarios, and we identify and compare acoustical metrics for auditory distance cues from acoustical fieldwork we conducted using this strategy in three contrasting case-study heritage sites. This conceptual shift from architectural acoustical sampling to aural heritage sampling prioritizes culturally and physically plausible human auditory/sound-sensing perspectives and relates them to spatial proxemics as scaled architecturally.
