Published: December 2020

Abstract

Background
Physical activity (PA) levels are low in patients with advanced chronic kidney disease (CKD), and associate with increased morbidity and mortality. Reliable tools to assess PA in CKD are scarce. We aimed to develop and validate a novel PA questionnaire for use in CKD (CKD-PAQ).

Methods
In Phase 1, a prototype questionnaire was developed based on the validated recent PAQ (RPAQ). Structured feedback on item relevance and clarity was obtained from 40 CKD patients. In Phase 2, the questionnaire was refined in three iterations in a total of 226 CKD patients against 7-day accelerometer and RPAQ measurements. In Phase 3, the definitive CKD-PAQ was compared with RPAQ in 523 CKD patients.

Results
In the final iteration of Phase 2, CKD-PAQ data were compared with accelerometer-derived and RPAQ data in 60 patients. Mean daily metabolic equivalent of task (MET) and total energy expenditure (TEE) levels were similar by all methods. Intraclass correlation coefficients showed fair (MET) and good (TEE) agreement between accelerometry and both CKD-PAQ and RPAQ. Agreement between questionnaires was excellent. The mean [standard deviation (SD)] daily MET bias was 0.035 (0.312) for CKD-PAQ and 0.018 (0.326) for RPAQ. The mean (SD) TEE bias was 91 (518) for CKD-PAQ and 44 (548) kcal for RPAQ. Limits of agreement (LOA) were wide for both parameters, with less dispersion of CKD-PAQ values. In Phase 3, agreement between questionnaires was good (MET) and excellent (TEE). Bias of CKD-PAQ-derived mean (SD) daily MET from RPAQ-derived values was 0.031 (0.193), with 95% LOA −0.346 to 0.409. Corresponding mean (SD) values for TEE were 48 (325) and −588 to 685 kcal/day. CKD-PAQ appeared to improve discrimination between low activity groups.

Conclusions
CKD-PAQ performs comparably to the RPAQ though it is shorter, easier to complete, and may better capture low-level activity and improve discrimination between low activity groups.
Biochemical Basis for Redox Regulation of Chloroplast-Localized Phosphofructokinase from Arabidopsis thaliana
Authors: Yoshida Keisuke , Hisabori Toru 
Published: December 2020

Abstract
Various proteins in plant chloroplasts are subject to thiol-based redox regulation, allowing light-responsive control of chloroplast functions. Most redox-regulated proteins are known to be reductively activated in the light in a thioredoxin (Trx)-dependent manner, but its regulatory network remains incompletely understood. Using a biochemical procedure, we here show that a specific form of phosphofructokinase (PFK) is a novel redox-regulated protein whose activity is suppressed upon reduction. PFK is a key enzyme in the glycolytic pathway. In Arabidopsis thaliana, PFK5 is targeted to chloroplasts and uniquely contains an insertion sequence harboring two Cys residues (Cys152 and Cys157) in the N-terminal region. Redox shift assays using a thiol-modifying reagent indicated that PFK5 is efficiently reduced by a specific type of Trx, namely, Trx-f. PFK5 enzyme activity was lowered with the Trx-f-dependent reduction. PFK5 redox regulation was bidirectional; PFK5 was also oxidized and activated by the recently identified Trx-like2/2-Cys peroxiredoxin pathway. Mass spectrometry-based peptide mapping analysis revealed that Cys152 and Cys157 are critical for the intramolecular disulfide bond formation in PFK5. The involvement of Cys152 and Cys157 in PFK5 redox regulation was further supported by a site-directed mutagenesis study. PFK5 catalyzes the reverse reaction of fructose 1,6-bisphosphatase (FBPase), which is reduced and activated specifically by Trx-f. Our data suggest that PFK5 redox regulation, together with that of FBPase, constitutes a checkpoint for switching light/dark metabolism in chloroplasts.
Renormalizable SO (10) grand unified theory with suppressed dimension-5 proton decays
Authors: Haba Naoyuki , Mimura Yukihiro , Yamada Toshifumi 
Published: December 2020

Abstract
We study a renormalizable supersymmetric (SUSY) $SO(10)$ grand unified theory model where the Yukawa couplings of single ${\bf 10}$, single ${\bf \overline{126}}$, and single ${\bf 120}$ fields ($Y_{10}$, $Y_{126}$, and $Y_{120}$) account for the quark and lepton Yukawa couplings and the neutrino mass. We pursue the possibility that $Y_{10}$, $Y_{126}$, and $Y_{120}$ reproduce the correct quark and lepton masses, Cabibbo–Kobayashi–Maskawa and Pontecorvo–Maki–Nakagawa–Sakata (PMNS) matrices and neutrino mass differences, and at the same time suppress dimension-5 proton decays (proton decays via colored Higgsino exchange) through their texture, so that the soft SUSY-breaking scale can be reduced as much as possible without conflicting the current experimental bound on proton decays. We perform a numerical search for such a texture, and investigate implications of that texture on unknown neutrino parameters, the Dirac CP phase of the PMNS matrix, the lightest neutrino mass, and the $(1,1)$-component of the neutrino mass matrix in the charged lepton basis. Here we concentrate on the case when the active neutrino mass is generated mostly by the Type-2 seesaw mechanism, in which case we can obtain predictions for the neutrino parameters from the condition that dimension-5 proton decays be suppressed as much as possible.
Nationalism in the produce aisle: Using country of origin labels to stir patriotism and animosity
Authors: Heiman Amir , Just David R 
Published: December 2020

Abstract
This study aims to determine how feelings of nationalism or patriotism for one's own country and feelings of animosity for countries that are in political conflict affect consumers’ willingness to refrain from buying products from various origins. Four hundred forty-two shoppers participated in a survey that included questions about ethnocentric and patriotic feelings and a choice task between local and foreign produce. We find that a significant proportion of Israeli consumers are not willing to buy imported produce from countries that are in conflict with Israel. The proportion of consumers who would not purchase imported produce increases substantially with the intensity of the conflict. Consumers who avoid buying produce from friendly countries are those whose ethnocentric and economic-centric relationship are strong.
The Effects and Safety of Continuous Positive Airway Pressure in Children with Bronchiolitis: A Systematic Review and Meta-Analysis
Authors: Tang Guojing , Lin Jilei , Zhang Yin , Shi Qingxia 
Published: December 2020

Abstract

Objectives
To evaluate the effects and safety of continuous positive airway pressure (CPAP) for initial respiratory management of bronchiolitis.

Methods
PubMed, EMBASE, Cochrane Library, CNKI, Wanfang data and CQ VIP were searched until 17 June 2020. Randomized controlled trials (RCTs) which investigated the effect of CPAP for bronchiolitis were included.

Results
Twenty-seven RCTs met the eligibility criteria. In the comparison of CPAP versus standard oxygen therapy, CPAP can reduce the length of stay (LOS) in hospital, respiratory rate (RR), PaCO2, heart rate, mechanical ventilation and increase PaO2, but the SpO2 and PH were not improved. In the comparison of CPAP versus high-flow nasal cannula, CPAP can reduce treatment failure, but the PICU LOS, Incidence of intubation, RR, Modified Woods Clinical Asthma Score were not decreased. Treatment failure may be less in helmet comparing with the mask though there was no quantitative analysis.

Conclusion
CPAP for the initial respiratory management significantly benefit children with bronchiolitis, the delivery of CPAP by helmet may be a better choice. More high-quality research is needed to confirm the conclusion.
What Do Neonatal Intensive Care Unit Policies Tell Us About Kangaroo Care implementation? A Realist Review
Authors: Fluharty Melissa , Nemeth Lynne S. , Logan Ayaba , Nichols Michelle 
Published: December 2020

Background:
Kangaroo care (KC) is recommended for infants during their stay in the neonatal intensive care unit (NICU) due to the benefits to infant growth, stabilized vital signs, and parental bonding; however, literature primarily explores the physiologic benefits, barriers, and facilitators to KC practice. Little is known about the context and mechanisms of KC implementation.

Purpose:
This realist review is to explore what NICU policies tell us about practices to implement KC in the NICU.

Methods:
Policies were obtained via email, database, and search engines. Criteria were established to review each policy. Data were entered into a database then exported for frequency counts of identified characteristics.

Results:
Fifty-one policies were reviewed, which revealed inconsistencies in the implementation of KC practices. Inconsistencies include variability in infant postmenstrual ages and weight criteria, infant medical equipment in place during participation, duration and frequency of KC, KC documentation, and ongoing monitoring requirements.

Implications for Practice:
KC implementation varies widely across NICUs, even with similar infant populations. Exclusion of some infants from receiving KC may decrease the potential beneficial outcomes known to result from KC.

Implications for Research:
More research to understand KC best practice recommendations and implementation in the NICU is needed. Studies are needed to evaluate the duration and frequency of KC, as well as the benefits to infants and families to optimize KC in the NICU setting.
Influence of ambipolar and Hall effects on vorticity in three-dimensional simulations of magneto-convection
Authors: Khomenko E. , Collados M. , Vitas N. , González-Morales P. A. 
Published: December 2020

This paper presents the results of the analysis of three-dimensional simulations of solar magneto-convection that include the joint action of the ambipolar diffusion and the Hall effect. Three simulation runs are compared: one including both ambipolar diffusion and the Hall effect; one including only ambipolar diffusion and one without any of these two effects. The magnetic field is amplified from initial field to saturation level by the action of turbulent local dynamo. In each of these cases, we study 2 h of simulated solar time after the local dynamo reaches the saturation regime. We analyse the power spectra of vorticity, of magnetic field fluctuations and of the different components of the magnetic Poynting flux responsible for the transport of vertical or horizontal perturbations. Our preliminary results show that the ambipolar diffusion produces a strong reduction of vorticity in the upper chromospheric layers and that it dissipates the vortical perturbations converting them into thermal energy. The Hall effect acts in the opposite way, strongly enhancing the vorticity. When the Hall effect is included, the magnetic field in the simulations becomes, on average, more vertical and long-lived flux tube-like structures are produced. We trace a single magnetic structure to study its evolution pattern and the magnetic field intensification, and their possible relation to the Hall effect.

High-frequency oscillations in small chromospheric bright features observed with Atacama Large Millimetre/Submillimetre Array
Authors: Guevara Gómez J. C. , Jafarzadeh S. , Wedemeyer S. , Szydlarski M. , Stangalini M. , Fleck B. , Keys P. H. 
Published: December 2020

We report detection of oscillations in brightness temperature, size and horizontal velocity of three small bright features in the chromosphere of a plage/enhanced-network region. The observations, which were taken with high temporal resolution (i.e. 2 s cadence) with the Atacama large millimetre/ submillimetre array (ALMA) in Band 3 (centred at 3 mm; 100 GHz), exhibit three small-scale features with oscillatory behaviour with different, but overlapping, distributions of period on the order of, on average, 90 ± 22 s, 110 ± 12 s and 66 ± 23 s, respectively. We find anti-correlations between perturbations in brightness, temperature and size of the three features, which suggest the presence of fast sausage-mode waves in these small structures. In addition, the detection of transverse oscillations (although with a larger uncertainty) may also suggest the presence of Alfvénic oscillations which are likely representative of kink waves. This work demonstrates the diagnostic potential of high-cadence observations with ALMA for detecting high-frequency magnetohydrodynamic waves in the solar chromosphere. Such waves can potentially channel a vast amount of energy into the outer atmosphere of the Sun.

Socialist political economy with Chinese characteristics in a new era
Authors: Hong Yinxing 
Published: December 2020

PurposeThe socialist political economy with Chinese characteristics reflects the characteristics of ushering into a new era, and the research object thereof shifts to productive forces. Emancipating and developing productive forces and achieving common prosperity become the main theme. Wealth supersedes value as the fundamental category of economic analysis.Design/methodology/approachThe theoretical system of socialist political economy with Chinese characteristics cannot proceed from transcendental theories but is problem-oriented. Leading problems involve development stages and research-level problems.FindingsThe economic operation analysis is subject to the goal of optimal allocation of resources with micro-level analysis focused on efficiency and macro-level analysis focused on economic growth and macroeconomic stability also known as economic security. The economic development analysis explores the laws of development and related development concepts in compliance with laws of productive forces. The new development concepts i.e. the innovative coordinated green open and shared development drive the innovation of development theory in political economy.Originality/valueAccordingly, the political economy cannot study the system only, but also needs to study the problems of economic operation and economic development. Therefore, the theoretical system of the political economy tends to encompass three major parts, namely economic system, economic operation and economic development (including foreign economy). The basic economic system analysis needs to understand the relationship between public ownership and non-public ownership, between distribution according to work and factor payments, and between socialism and market economy from the perspective of coexistence theory, thus transforming institutional advantage into governance advantage.
The adoption of ecopreneurship practices in Indonesian craft SMEs: value-based motivations and intersections of identities
Authors: Gunawan Arien Arianti , Essers Caroline , van Riel Allard C.R. 
Published: December 2020

PurposeThis article explores value-based motivations to adopt ecological entrepreneurship (ecopreneurship) practices and investigates how intersections of social identities such as gender, religion and ethnicity influence these motivations.Design/methodology/approachThe study uses primary data from field observations, social media analysis and semistructured in-depth interviews with 16 owner-managers of small and medium enterprises (SMEs) in the Indonesian craft sector.FindingsThe findings show that self-enhancement, conservation and self-transcendence values motivated the entrepreneurs to adopt ecopreneurship practices. Furthermore, the intersections of identities also tended to influence the entrepreneurs' motivations to adopt ecopreneurship practices.Research limitations/implicationsThe sample was limited to the Indonesian craft sector. However, the study has furthered one’s understanding of how values motivate ecopreneurship behavior. Conservation values were added to the values known to influence proenvironmental behavior. Furthermore, Schwartz's value theory, strongly associated with Western, individualistic, culture is suggested to be adapted. In Asian – collectivist – cultures, the values driving the entrepreneur are often more community-oriented than individualistic.Practical implicationsThis study recommends policymakers to create more inclusive policies to foster the acceleration of sustainable development by equitably including both genders and encourages them to promote local culture, which motivates entrepreneurs in the craft sector to adopt ecopreneurship practices.Originality/valueThe study contributes to the entrepreneurship literature, particularly to the fields of gender and ecopreneurship, by considering the intersections of identities of the ecopreneurs. A research agenda for ecological entrepreneurship and family business researchers is provided.
To partner or not? A study of co-branding partnership and consumers' perceptions of symbolism and functionality toward co-branded sport products
Authors: Yu Ho Yeol , Robinson G. Matthew , Lee DongHun 
Published: December 2020

PurposeThis study was conducted to examine the effect of co-branding, a brand partnership tactic involving two or more brands, on consumer behavior within the sport industry. As such, the primary aim was to examine differences regarding consumers' perceptions of self-image congruence and perceived product quality when considering solo-branding and co-branding conditions. Further, under the co-branding condition, relationships among consumers' self-image congruence, perceived product quality, image fit, product evaluation and purchase intention were investigated.Design/methodology/approachA scenario-based quasi-experiment consisting of hypothetical co-branding initiatives between existing brands was conducted.FindingsResults from a repeated multivariate analysis of variance (MANOVA) indicated that consumers' symbolic and functional perceptions of co-branding as well as evaluations were statistically higher than in the solo-branding condition. Additionally, structural equation modeling indicated positive relationships between consumers' symbolic and functional perceptions, image fit, evaluation and behavior intention.Originality/valueThis study is one of the first papers to investigate the impact of co-branding on consumers within the sport industry and provides evidence of the positive impact of co-branding strategies on consumer behavior within the sport industry.
Information professionals' soft skills status and barriers in its development: a mixed method study
Authors: Ahmad Sajjad , Ameen Kanwal , Ahmad Shehzad 
Published: December 2020

PurposeThe purpose of this study is to investigate the self-perceptions of university information professionals about the current state of their soft skills and to highlight the barriers faced in the development of such skills.Design/methodology/approachA sequential mixed method research design using a questionnaire followed by in-depth interviews as data collection tools were used to achieve the objectives of the study. Self-completion questionnaires were used to collect the data from 560 respondents spread over 33 universities of Pakistan. Then, 21 interviews were conducted with purposely selected library and information professionals at the qualitative phase.FindingsThe findings of the survey revealed that the majority of the information professionals perceived themselves “moderately competent” in soft skills. Only 14.8% information professionals considered themselves “competent”. The qualitative findings revealed that university library and information professionals generally faced several barriers in the development of their soft skills that included “lack of administrative support”, “lack of personal commitment”, “lack of financial support by the parent organizations”, and so many others, which might have affected their current levels of soft skills.Research limitations/implicationsThe possible limitation of this study may be the bias of the respondents, toward their self-judgment. During interviews, most of the assistant librarians were not comfortable and expressive. This might be due to lack of soft skills knowledge, interview anxiety and poor communication skills.Originality/valueThis research is the first study in Pakistan that dealt with the state of soft skills and barriers in its development among university library and information professionals having a large number (N = 372) of respondents.
Real options flexibility or risk diversification: risk management of US MNEs when facing risk of war
Authors: Yeo Yun Dong , Lee Seung-Hyun (Sean) 
Published: December 2020

PurposeThe purpose of this paper is to examine how the risk of war aroused by North Korea’s threatening actions trigger strategic responses from US multinational enterprises (MNEs) operating in South Korea. The authors compare two competing perspectives of real options and risk diversification to see which prevails when US MNEs are facing risk of war.Design/methodology/approachThe authors hand collected news articles regarding North Korea’s threatening actions that may trigger strategic responses from MNEs operating in South Korea. The authors use archival data of US MNEs to verify our results.FindingsEmpirical tests of the two competing perspectives reveal that US MNEs adopt the risk diversification strategy when threatened by the risk of war. However, as MNEs have more available foreign markets outside the host country that is at risk of war, MNEs tend to take an operational flexibility approach more seriously and shift their productions to the remaining global operations. The ownership structure of the subsidiary does not appear to have significant effect on US MNEs’ strategic risk management.Originality/valueThis paper compares two perspectives, namely, real options and risk diversification, to observe how US MNEs treat their subsidiaries when facing risk of war in South Korea.
