Hypobaric Storage of Representative Root, Leaf, Fruit, and Flower Tissues: Comparisons to Storage at Atmospheric Pressure and Normoxia

Hypobaric or low-pressure storage (LPS) is a technology that has been reported to have significant potential to preserve fresh produce quality. However, excessive moisture loss has often been erroneously reported to limit the utility of LPS. We report on hypobaric (1.6 to 2.0 kPa) storage of representative bulky and leafy fruits and vegetables {strawberry (Fragaria ×ananassa Duchesne ex Rozier) fruit, carrot [Daucus carota subsp. sativus (Hoffm.) Arcang. ] roots, spinach (Spinacia oleracea L.) leaves, and rose (Rosa ×hybrida ‘Attaché Pink’) flowers} using a laboratory-scale LPS and provide data on the regulation of humidity and temperature and describe effects on moisture loss and quality. The LPS achieved near saturation (>99.5%) of water without condensation on the chamber sidewalls. This required tight regulation of the chamber wall temperature (2.2 °C ± 0.15 °C) and careful control of the flux of air into the chamber. The rate of moisture loss was unaffected by the pressure of the storage atmosphere; however, it was affected by commodity, being lower for strawberry than for carrot or spinach, and averaging 0.08%, 0.40%, and 0.35% per day, respectively (average of normal and low pressure combined). Moisture loss of long-stemmed rose in LPS averaged 0.071% per day over an 8-week storage period. Although moisture loss was low, the LPS environment appeared to enhance water loss from deeper within plant tissues than storage at atmospheric pressure and, in roses, resulted in bent neck 2 or 3 days after removal from storage after 3 weeks. For this reason, LPS did not benefit storability of cut ‘Attaché Pink’ roses compared with high-humidity chambers maintained at atmospheric pressure.
Enhanced electroactive β-phase nucleation and dielectric properties of PVdF-HFP thin films influenced by montmorillonite and Ni(OH)2 nanoparticle modified montmorillonite

The present work lays emphasis on the synthesis of electroactive and high dielectric poly(vinylidenefluoride-co-hexafluoropropylene) (PVdF-HFP) composite films incorporated with montmorillonite (MMT) and Ni(OH)2 nanoparticle (NP) modified MMT using a facile and low cost solution casting technique. Formation of Ni(OH)2 NPs, different polymorphs and morphology of the composite samples have been investigated using UV-visible spectroscopy, X-ray diffraction, Fourier transform infrared spectroscopy, differential scanning calorimetry and field emission scanning electron microscopy. A remarkable improvement in β-phase nucleation (∼85.22% for 1 mass% MMT doped at and 82.10% for 7.5 mass% NiMMT doped polymer composites films) and promising dielectric values are the standpoints of the work. Strong ion–dipole interaction between the negatively charged surfaces of MMT and –CH2 dipoles of the polymer chains in the MMT loaded PVdF-HFP samples and formation of hydrogen bonds between the –OH group of Ni(OH)2 NPs and F atom of the polymer chains in the Ni(OH)2 NP-MMT/PVdF-HFP system play a dynamic role in enhancing the electroactive β-phase nucleation and the dielectric properties of the samples. A large accumulation of charges at the interfaces of the dopant and polymer matrix via Maxwell–Wagner–Sillars interfacial polarization effect occurred due to the disparity in the conductivity of the dopants and the polymer matrix is liable for the significant enrichment of dielectric properties of the composite films. Excellent thermal stability in dielectric properties has also been observed in these composite samples over a wide temperature spectrum. These electroactive and high dielectric polymer composite thin films may be potential candidates for application in piezoelectric nanogenerators, energy storage devices, thin film transistors and capacitive sensors etc.
Chemical characteristics of soil organic matter from integrated agricultural systems in southeastern Brazil

Soil organic matter (SOM) plays an essential role in agronomic systems and is of great importance to environmental sustainability and carbon sequestration. This study evaluates the accumulation of carbon in soils from integrated agricultural systems (S) that include crop (C), livestock (L), and forest (F) components (in different combinations: CLFS, LFS and CLS) and an undisturbed native forest (NF) as a reference area. The study sites are part of the Embrapa Pecuária Sudeste research station located in the southeast of Brazil in a region of dystrophic Red‐Yellow Latosol soils. Stable carbon isotopic analysis (δ13C) and solid‐state 13C nuclear magnetic resonance (13C NMR) spectroscopy were used to evaluate the chemical characteristics of humic acid (HA) extracts of soils from different soil horizons. The findings were discussed in the context of laser‐induced fluorescence spectroscopy (LIFS) measurements on the whole soils and carbon content on both the whole soils and HA extracts. With increasing depth of the soil horizons, bulk SOM (in the whole soil) and a more recalcitrant humic fraction (the HA) became enriched in carbon, indicative of accumulation. Isotopic analysis revealed that SOM in the crop‐livestock‐forest system exhibited δ13C signatures corresponding to C4 plants (grass and corn). The native forest exhibited a uniform δ13C signature characteristic of C3 plants (native trees). Benzenepolycarboxylic acids (BPCA) quantification on limited samples revealed condensed aromatic structures in both crop‐livestock‐forest system and native forest. The absence of burning suggests that these compounds come from the humification of lignin. Based on structural characterization, carbon is sequestered as recalcitrant and long‐lived oxidized ligninaceous structures and condensed aromatic groups. The current research demonstrates the feasibility of novel agricultural approaches such as using crop‐livestock‐forest systems. Such pastureland management enhances higher agricultural productivity and sustainability, thus avoiding new deforestation of native areas.
Organizational justice, life satisfaction, and happiness: the mediating role of workplace social courage

PurposeWorkplace social courage is a courageous behavior that can damage the actor's social relationships, social image and accrue face-loss costs. Sometimes, it is difficult to differentiate courageous behavior from incivility that predicts higher levels of psychological distress. While workplace social courage is widely discussed in the management literature, less is known about the conditions under which individuals are more or less likely to exhibit courageous behaviors. Given the theoretical considerations, in the present study, the authors consider two indicators of quality of life, which are life satisfaction and happiness, and set the aim of the study as to investigate the relationships between organizational justice and two dimensions of quality of life – life satisfaction and happiness – with particular attention to the mediation function performed by courage.Design/methodology/approachCross-sectional survey data (n = 408) were obtained from employees working in Turkey Fortune companies and analyzed with variance-based structural equation modeling (VB-SEM) technique.FindingsThe results showed that perceived organizational justice is a strong antecedent for workplace social courage. Workplace social courage emerges as a facilitator for subjective happiness and life satisfaction. Workplace social courage mediated the association between perceived organizational justice and subjective happiness, and between perceived organizational justice and life satisfaction. Prescriptions for theory development and practitioners are highlighted, research limitations and future directions are acknowledged.Originality/valueSo far, most of the work done in this subject is mainly in western countries, and it is considered as a virtue, feature, emotion and behavior in the studies of social scientists, and mainly focused on how employees need the courage to perform the desired behaviors that affect organizational outcomes positively such as organizational citizenship behavior, job performance, job satisfaction, life satisfaction, psychological well-being. Also, the authors studied how social courage positively relates to beneficial voice and silence, as well as negatively relates to detrimental voice and silence, how courage is correlated with psychological empowerment, coaching and how courage mediates on quality of life. As can be seen, there is little empirical work when it comes to the antecedents of courage in business life. Therefore, this study, which has been done with different variables in a different culture and country, aims to support and bring a new breath to the subject. Besides, the mediating effect of courage on the organizational variables is also among the trendiest subjects.
Woody Species Composition, Vegetation Structure, and Regeneration Status of Majang Forest Biosphere Reserves in Southwestern Ethiopia

The aim of this study was to analyse the species composition, structures, and regeneration of woody plant species and the impacts of site factors on the natural regeneration of tree species in four study sites of MFBR. The vegetation data were collected systematically in 140 plots with the size of 400 m2 for trees; 25 m2 for seedlings, saplings, shrubs, and lianas; and 1 m2 for herbs. Individual tree and shrub DBH ≥ 5 cm were measured and counted. The diameter at breast height (DBH), frequency, basal area, importance value index (IVI), and density were used for vegetation structure description and regeneration. A total of 158 plant species belonging to 115 genera, 56 families, and 80 species (51%) trees, 26 (16%) shrubs, 19 (12%) herbs, and 33 (21%) lianas were identified and recorded. The most dominant families were Euphorbiaceae, Rubiaceae, and Moraceae, each represented by 13 species (7.4%), 12 species (6.8%), and 10 species (5.7%), respectively. The tree densities varied from 1232 to 1478 stem ha−1, sapling density 176.8 to 708.7 stem ha−1, and seedling density 534.7 to 1657.5 stem ha−1, with an average basal area of 63.6 m2 in the study sites. Dracaena afromontana was the most frequent woody species in the MFBR occurring in 90% followed by Celtis zenkeri (65%) and Pouteria altissima (62.5%). The regeneration status of all the woody plant species was categorised as “not regenerate” (9.6%), “poor” (30.7%), “fair” (59.5%), and “good” (10.8%) in all sites. The correlation result between natural regeneration and site factors revealed both positive and negative relationships. However, the main threat to the biosphere reserve is illegal logging for different purposes. Therefore, awareness creation on sustainable forest management, utilisation, conservation of priority species, and livelihood diversification to the local community and encouraging community and private woodlot plantation in the transitional zone of biosphere reserves are recommended.
Digital Financial Inclusion Sustainability in Jordanian Context

Digital Financial Inclusion (DFI) refers to efforts to make digital financial services available and affordable to all individuals and institutions, regardless of their net expense or institution size and demographic location. Despite the immense benefits of DFI and DFI-based products and services such as mobile money and payment systems, users’ acceptance is thin, limited, and disappointing in some developing countries as Jordan. Consequently, this study has investigated the factors influencing the acceptance of the mobile payment system in the Jordanian context. This study’s research model synthesizes the Technology Acceptance Model (TAM) variables and extended the model with perceived financial cost as an independent variable. The research model has been empirically confirmed by fitting the model to data collected from 304 Jordanian citizens using a survey instrument. The data were analysed using Partial Least Squares-Structural Equation Modelling (PLS-SEM). The result has confirmed that behavioural intention to use the m-payment system is significantly and positively influenced by perceived usefulness and perceived financial cost; behavioural intention to use m-payment system was not found to be significantly and positively influenced by perceived ease of use and hence the related hypothesis was not supported. Finally, conclusions and recommendations are further discussed in the last section of this paper.
Survival in Patients with Acute Lymphoblastic Leukemia and COVID-19 in Mexico

Aims: To determine the survival of patients with acute lymphoblastic leukemia and COVID-19. Study Design: Prospective, analytical and relational. Place and Duration of Study: Hematology department, Hospital of Specialties, High Specialty Medical Unit, National Medical Center "Gral. Manuel Avila Camacho", Puebla, Mexico, during the period June 2020-April 2021 Methodology: Patients aged 15 to 64 years, both sexes, with acute lymphoblastic leukemia and a confirmed diagnosis of COVID-19 by PCR. The variables included were; sex, age (groups: 15-20; 21-29; 30-39; 40-49; 50-59; and 60-64), comorbidities, general treatment and hematological treatment response. Survival was determined for the diagnosis of COVID-19 for 11 months, using Original Research Article Martinez et al.; IBRR, 12(3): 32-39, 2021; Article no.IBRR. 68658 33 the Kaplan Meier estimator and the Log-Rak test; Cox regression model (univariate and multivariate); as well as Chi square and V-Cramer with a 95% confidence interval and using the statistical program SPSS Ver. 25. Results: The study consisted of 20 patients, of which 33.3% were women, with an average age of 37.75 ± 11.63 years; The men registered an age of 28.50 ± 18.05 years. Overall survival was 50%, with a lower limit of 101.3 and an upper limit of 242.5 days, with a mean of 171.9 days; and median at 17 days. No significant differences were found in survival regarding sex, comorbidities, general treatment and hematological response. However, mortality in patients with comorbidities was higher (p = 0.051). Conclusion: Survival in patients with acute lymphoblastic leukemia and COVID-19 is low, due to complications that increase mortality, mainly owing to hematological suppression, and even more so with the presence of comorbidities.
Bearing estimation of low probability of intercept sources via polynomial matrices and sparse linear arrays

Recent years have seen a steady convergence of Radar and Communications band Radio Frequency (RF) transceiver systems. Not only have Communications systems colonised large swathes of previously allocated Radar bands but there is also a convergence of technologies driven by the relatively low cost of software-defined transceivers and solid-sate RF sources. Thus, where conventional radar transmissions are characterised by short narrowband pulses with high peak power, new classes of 'pulse-compression' radar are being developed to exploit this new technology. The resulting Low Probability of Intercept waveforms are designed to spread energy in both time and frequency, yielding a very low instantaneous power spectral density. Methods to detect, analyse and distinguish such sources require longer acquisition periods to collect more energy from the sources. Here, a novel solution is provided for detection and separation based on direction-finding utilising polynomial matrix methods in conjunction with sparse array geometries. This approach provides enhanced detection, separation and direction finding while using relatively few antenna elements.
Improving the Speaking Skill of Primary School Students Instructed in a Multigrade Class through Cartoons

In the current study, it is aimed to improve the speaking skill of primary school students instructed in a multigrade class through cartoons. The current study employed the action research design. Participants of the study are 3rd and 4th grade primary school students instructed in a multigrade class in a village school in the city of Kahramanmaras in Turkey in the 2019-2020 school year. The data in the study were collected through observations, interviews and documents. A program consisting of 7 applications in which cartoons are used for students with speech problems was prepared and applied within the scope of the language teaching course. The application continued for four weeks until the students' speech problems were reduced to a certain level and they achieved some improvement in speaking. Plans were prepared every week in line with the opinions of the field experts and the development status of the students in speech was evaluated. At the end of the study, the students' opinions about the application were taken through semi-structured interviews. At the end of the study, it was observed that the speech errors of the students decreased. At the same time, it was determined that there was an increase in the speaking time of the students and the number of words and sentences they used. The most important and positive change occurred in the psychological dimension of speech. Students' motivation increased and they started to behave more comfortably when speaking. In this direction, their anxiety decreased and their desire to speak increased. Furthermore, positive changes occurred in the students' adjustment of their tones and sound intensities. The words spoken by the students became more comprehensible.
Decoupled Soil Labile Carbon and Nitrogen Dynamics Triggered by Urban Vegetation

Purpose Studies about soil carbon (C) and nitrogen (N) dynamics with land use change are urgently needed for urban ecosystems. We used fractionation of soils combined with stable isotopic analysis to examine soil C and N cycles after decadal forest and lawn planting in the Pearl River Delta, China. Methods Soil samples from bare soil (CK) and four land use treatments (55 and 20 years of forest plantation, F-55 and F-20; 55 and 20 years of lawn plantation, L-55 and L-20) were split into different chemical fractions. Then we analyzed the C and N contents, C/N ratio, δ13C and δ15N, C and N recalcitrant indices (RIC, RIN), and a C pool management index (CPMI). Results Forest vegetation substantially enhanced soil organic carbon (SOC) caused by the recalcitrant (RC) and labile C (LC) pools, while the larger soil organic nitrogen (SON) was ascribed to the increased recalcitrant N (RN). Enhanced LC but minor changes in labile N (LN) suggested a decoupled C and N in labile fractions of the forest soils. In contrast, the larger LN, and the enhanced decomposition of SOC, indicated that the lawns may have inhibited N mineralization of labile pools, also suggesting a decoupled C and N turnover and leading to low RIN values. Conclusions Urban forest and lawn plantations significantly changed the soil C and N dynamics, and emphasized the inconsistency between C and N processes, especially in labile pools, which would eventually lead to minor changes in N and limit the ecosystem C sequestration.
Rurality as Concordance: Mental Health Service Delivery for Rural Survivors of Intimate Partner Violence

This manuscript examines how a shared sociospatial or “rural” identity may uniquely facilitate mental health care delivery. In particular, we consider the significant but largely unexplored role that domestic violence center staff, whom we term “Reputational Provider-Experts” or RPEs, play in addressing the mental health needs of rural women who have experienced intimate partner violence. Using data collected through semi-structured individual and focus group interviews with RPEs across 12 counties and four tribal reservations in northern Wisconsin (N = 15), we detail the sociospatial commonalities that enable RPEs to provide trusted, sustained mental health support to rural women. Because these advocates are rural community members whose approach implicitly appeals to local norms and values, we argue that they represent rurally concordant providers. In this way, rurality emerges as a meaningful and novel form of patient-provider concordance, one with critical relevance to addressing the rural mental health crisis in the United States.
Dance movement therapy for depressed clients: Profiles of the level and changes in depression

ABSTRACT This research identified participant profiles in level and changes in depression among working age (18–64 years old) clients (N = 137) diagnosed with depression, who participated in a 20-session dance movement therapy (DMT) intervention. Using Latent Profile Analysis Mild, sharply reducing depression (9%), Mild, reducing depression (58%) and Severe, reducing depression (33%) profiles were established, using Beck Depression Inventory scores gathered at pre-intervention, post-intervention, and follow-up points. At the pre-intervention point, being in full-time work was related to the Mild, sharply reducing depression profile. Being on a disability pension, having a history of one`s own or a close person`s substance abuse, a more fearful attachment style, and deficiencies in mindfulness skills were related to the Severe, reducing depression profile. All participants benefited from the short-term DMT intervention, which may offer a good outcome for patients with less complex depression, whereas those with more complicated symptomology may require longer treatment.
My choices are better than yours! Gender differences in narcissistic start-up entrepreneurs

PurposeThe paper explores the role of narcissism on entrepreneurs' decisions in terms of organizational choices, discussing gender differences. The aim relies in the influence that entrepreneurs' personality, capabilities and cognitive orientation have in the creation and management of start-ups.Design/methodology/approachAnalyzing an Italian sample of 207 entrepreneurs and using Analysis of variance (ANOVA) and generalized linear model methods, the hypotheses were tested to understand whether and how narcissism affects Research and development (R&D) expenditure, patent ownership and the presence of a specialized team in organizations led by women and men entrepreneurs.FindingsDifferences in the management and organizational choices of narcissistic women entrepreneurs compared to their men counterparts emerged. First, results show that women entrepreneurs are less narcissistic than men. Second, gender is shown to moderate the effect of narcissism on the choice of having a qualified team in a start-up. Third, narcissistic women entrepreneurs were found to engage less in risk-taking activities, such as R&D expenditure, and to patent their ideas more than their male counterparts.Originality/valueThe study expands the existing literature by applying a gendered lens to entrepreneurs' narcissism to investigate whether they behave and manage their start-ups differently.
