Value of work in the Netherlands: the role of the organisation

In recent scientific and policy discourses, the centre of attention is increasingly geared towards the value and quality of work – as opposed to a prior occupation with the quantity of work. Whereas the dominant focus seems to be on (aspects of) the individual job, this contribution aims to embed the worker into the organisational context and highlight the (potential) role of organisations. We examine whether the value of work – beyond individual and job characteristics – is affected by (a) characteristics of the organisation, (b) mutual investments or the relation between employees and employers and (c) the extent to which employees can realise their values within an organisation. To that end, we analyse survey data from the Value of Work Monitor 2019. Our findings show that not only the characteristics of the employment relationship, but also the organisational context and realisation of workers’ values have a significant effect on the evaluation of one’s job. Amongst others, the composition of the workforce, autonomy and intensity, facilities for lifelong learning and workers’ embeddedness in the organisation all have a significant effect on outcomes. We conclude that the discussion on value and quality of work deserves a more active role from the side of employers.

Energy and democracy: on the democratization of complex governance processes

This article clarifies the democratic problems of multilevel governance, with a focus on the Regional Energy Strategy decision-making process. First, the risks that these democratic problems entail for democratic support and for the quality and speed of decision-making are discussed. Next, these problems – and their possible solutions – are discussed by means of three approaches to democracy: representative democracy, pluralist democracy and participatory democracy. A tailor-made mix of these three approaches is recommended as most useful for a solid democratic anchorage of multilevel governance.

The Blind Spot

The most relevant part of a discussion is not what is discussed but what cannot be spoken of. The real taboos are those for which it is taboo to call them taboos. The status quo defines itself as non-ideological while denouncing any challenge to itself as radical.

Therefore the column De blinde vlek frames the framers, politicizes the status quo and articulates what is not heard of.

Heimelijke toepassing van openlijke bevoegdheden

In het nieuwe wetboek worden ‘nieuwe’ opsporingsbevoegdheden geïntroduceerd die normaal gesproken openlijk worden toegepast maar straks ook heimelijk mogen worden ingezet. Het betreft het vergelijkend vingerafdrukken- en handpalmonderzoek, het handschrift- en stemvergelijkend onderzoek, inbeslagneming van voorwerpen en de inzet van daartoe strekkende steunbevoegdheden, het bij gelegenheid van een doorzoeking of betreden van plaatsen overnemen van gegevens en het bevel tot verstrekken van gegevens. In het artikel wordt aangegeven dat de invoering van deze bevoegdheden noodzakelijk en ook wenselijk is, waarbij de wettelijke regeling bovendien voldoet aan de eisen die daaraan door het EHRM worden gesteld. Het voordeel van codificatie is bovendien dat waar het nu vaak om een ongeregelde praktijk gaat, door codificatie duidelijk wordt onder wiens gezag de toepassing van de bevoegdheid valt en aan welke voorwaarden moet zijn voldaan voordat de bevoegdheid mag worden toegepast.
Functional Asplund metrics for pattern matching, robust to variable lighting conditions
Authors: Noyel Guillaume , Jourlin Michel
Published: June 2020

In this paper, we propose a complete framework to process images captured under uncontrolled lighting and especially under low lighting. By taking advantage of the Logarithmic Image Processing (LIP) context, we study two novel functional metrics: i) the LIP-multiplicative Asplund metric which is robust to object absorption variations and ii) the LIP-additive Asplund metric which is robust to variations of source intensity or camera exposure-time. We introduce robust to noise versions of these metrics. We demonstrate that the maps of their corresponding distances between an image and a reference template are linked to Mathematical Morphology. This facilitates their implementation. We assess  them in various situations with different lightings and movement. Results show that those maps of distances are robust to lighting variations. Importantly, they are efficient to detect patterns in low-contrast images with a template acquired under a different lighting.
Effective time interval for railway track geometry inspection
Authors: Kasraei Ahmad , Zakeri Jabbar Ali
Published: June 2020

A proper decision-making scheme for track geometry maintenance requires a knowledge of the real condition of track geometry. Therefore, the track must be inspected by measurement cars at different time intervals. The frequency of track geometry inspection plays a crucial role in decision-making and has always been a big concern for infrastructure managers. The inspection interval should be chosen properly, it means that the small period can decrease the capacity of line and affect the operation of network and the big period can result in low quality of track and in some cases derailments and possible loss of human lives. The aim of this paper is to determine the effective inspection interval such that the total maintenance cost is minimized. In the proposed cost model, the costs of inspection, preventive maintenance, corrective maintenance and the penalty for exceeding the corrective maintenance level are considered. A case study is performed on a real dataset collected from a railway line in Iran. The standard deviation of longitudinal level is considered to measure track geometry degradation. A widely applied linear model is used to model track geometry degradation over time. Monte Carlo technique is used to simulate the track geometry behavior under various track geometry inspection intervals. In addition, a set of sensitivity analyses are carried out to assess the effect of various inspection intervals on different terms of maintenance cost. The results indicate that not only can substantial costs be saved by setting effective inspection intervals, but also the time during which the track suffers from bad conditions is dramatically reduced. The result of this study has shown the appropriate inspection interval for the studied case can result in 13.6 percent decrease in maintenance cost in comparison with the current maintenance policy. Besides, it would lead to more reliable railway track by preventing the system exceed the corrective threshold.
Influences of Weight Loss and Physical Exercise on Lipid Panel in Overweight Middle-Aged Men
Authors: Rezaeipour Mohammadreza , Gennady Leonidovich Apanasenko
Published: June 2020

Background: Cardiovascular risk is reduced by weight loss and exercise, but their relative effects and independent significance are unclear. Objectives: The effect of weight loss and the implementation of an exercise strategy on the lipid panel of overweight middle-aged men, who lead a sedentary lifestyle, was investigated. Methods: Eighty four men participated in this 12-week cross-sectional study. Participants were randomly assigned to the four study groups: endurance sports, energy-restricted diet, endurance sports with boosted nutrition, and control. The energy reduction rate was the same (approximately 15% of the daily calorie requirement) for the group involved in endurance sports and for the group with an energy-restricted diet. The participants in the endurance sports with boosted nutrition performed the same exercises but remained in energy balance due to a 15% increase in calories during training. Participant lipid panel profile and weight loss parameters were measured once at the start of the study, and again at the end. Results: Weight loss was the same between the endurance sports (-6.5 ± 0.6 kg) and energy-restricted diet (- 6.2 ± 0.5 kg) groups. Whereas in the endurance sports with boosted nutrition (-0.8 ± 0.4 kg), and control (-0.1 ± 0.7 kg) groups, weight remained constant. Levels of TC and LDL-C decreased in the endurance sports compared to the control group (P < 0.001 for both). This change was not observed in the energy-restricted diet group (P > 0.11). Differences in TC and LDL-C levels were connected with changes in body mass (P < 0.01). In the endurance sports with boosted nutrition group, we noted a rise in HDL-C (P < 0.001). Conclusions: A decrease in body weight caused by exercise reduced pro-atherogenic lipoproteins, while physical activity compensated with energy consumption increased HDL-C.

Este análisis, nos permitirá comprender mejor la importante repercusión de estas antiguas enseñanzas en la práctica y filosofía de Mindfulness tal y como está siendo propagado y extendido por Occidente.
Alteridad y reconocimiento en la ontología monadológica de Leibniz
Authors: Casales García Roberto
Published: June 2020

El objetivo principal del presente trabajo de investigación es esclarecer el papel de la alteridad y el reconocimiento en Leibniz, tanto en su lógica de la alteridad y su teoría de la justicia universal, como en su fundamentación ontológica en la naturaleza expresiva y composible de los espíritus. Para lograr este objetivo, he dividido esta investigación en dos partes: en la primera parte busco mostrar en qué medida la alteridad y el reconocimiento son indispensables para comprender la filosofía práctica del hannoveriano; mientras que en la segunda busca analizar la naturaleza expresiva y composible de los espíritus, a fin de articular una incipiente fundamentación ontológica de la moral leibniziana.

Música, mujeres y simulacros: la imagen de la feminidad en Zuloak de Fermin Muguruza
Authors: Gajewska Magdalena Anna
Published: June 2020

A pesar de que el rock radical vasco fue un movimiento musical de gran alcance que marcó a toda una generación, contó con escasos grupos femeninos. Fermin Muguruza, uno de los personajes más relevantes de aquel movimiento, en su falso documental Zuloak (2012) toma como punto de partida la ausencia femenina en la tradición del punk vasco. La película trata sobre un grupo femenino de rock formado para la lmación que, después del estreno del lme, tuvo una gira real. Muguruza logra entonces crear un tipo de realidad paralela emparentada con lo que Jean Baudrillard (1978) entiende como un simulacro. En el presente artículo llevaré a efecto un análisis antropológico-morfológico; se trata de un método para investigar la obra fílmica que pone atención en las relaciones entre los recursos formales, el contenido y las referencias al mundo fuera de la cción. Se analizará cuáles son los modelos de feminidad que se recrean en Zuloak, cómo funcionan y qué valor tienen. Además, con apoyo en la noción de hiperrealidad del mismo Baudrillard, se intentará echar luces sobre cómo se puede interpretar la visión del director en lo tocante a la situación de la escena vasca actual.
The testis protein ZNF165 is a SMAD3 cofactor that coordinates oncogenic TGFβ signaling in triple-negative breast cancer
Authors: Gibbs Zane A , Reza Luis C , Cheng Chun-Chun , Westcott Jill M , McGlynn Kathleen , Whitehurst Angelique W
Published: June 2020

Cancer/testis (CT) antigens are proteins whose expression is normally restricted to germ cells yet aberrantly activated in tumors, where their functions remain relatively cryptic. Here we report that ZNF165, a CT antigen frequently expressed in triple-negative breast cancer (TNBC), associates with SMAD3 to modulate transcription of transforming growth factor β (TGFβ)-dependent genes and thereby promote growth and survival of human TNBC cells. In addition, we identify the KRAB zinc finger protein, ZNF446, and its associated tripartite motif protein, TRIM27, as obligate components of the ZNF165-SMAD3 complex that also support tumor cell viability. Importantly, we find that TRIM27 alone is necessary for ZNF165 transcriptional activity and is required for TNBC tumor growth in vivo using an orthotopic xenograft model in immunocompromised mice. Our findings indicate that aberrant expression of a testis-specific transcription factor is sufficient to co-opt somatic transcriptional machinery to drive a pro-tumorigenic gene expression program in TNBC.
Silicon induces hormetic dose-response effects on growth and concentrations of chlorophylls, amino acids and sugars in pepper plants during the early developmental stage

Published: June 2020

Background

Silicon (Si) is a beneficial element that has been proven to influence plant responses including growth, development and metabolism in a hormetic manner.

Methods

In the present study, we evaluated the effect of Si on the growth and concentrations of chlorophylls, total amino acids, and total sugars of pepper plants (Capsicum annuumL.) during the early developmental stage in a hydroponic system under conventional (unstressed) conditions. We tested four Si concentrations (applied as calcium silicate): 0, 60, 125 and 250 mg L−1, and growth variables were measured 7, 14, 21 and 28 days after treatment (dat), while biochemical variables were recorded at the end of the experiment, 28 dat.

Results

The application of 125 mg L−1Si improved leaf area, fresh and dry biomass weight in leaves and stems, total soluble sugars, and concentrations of chlorophyllsaandbin both leaves and stems. The amino acids concentration in leaves and roots, as well as the stem diameter were the highest in plants treated with 60 mg L−1Si. Nevertheless, Si applications reduced root length, stem diameter and total free amino acids in leaves and stems, especially when applied at the highest concentration (i.e., 250 mg L−1Si).

Conclusion

The application of Si has positive effects on pepper plants during the early developmental stage, including stimulation of growth, as well as increased concentrations of chlorophylls, total free amino acids and total soluble sugars. In general, most benefits from Si applications were observed in the range of 60–125 mg L−1Si, while some negative effects were observed at the highest concentration applied (i.e., 250 mg L−1Si). Therefore, pepper is a good candidate crop to benefit from Si application during the early developmental stage under unstressed conditions.

Authors: Chang Chih-Ming , Tan Ting-Wan , Ho Tai-Cheng , Chen Chung-Chu , Su Tsung-Hsien , Lin Chien-Yu
Published: June 2020

Background

Coronavirus disease 19 (COVID-19) is a global health threat with significant medical, economic, social and political implications. The optimal strategies for combating COVID-19 have not been fully determined and vary across countries.

Methods

By the end of February 2020 in Taiwan, 2,150 patients received diagnostic COVID-19 testing and 39 confirmed cases were detected. This is a relatively lower rate of infection compared to other Asian countries. In this article, we summarize the epidemiological characteristics of the 39 infected patients as well as public and hospital responses to COVID-19.

Results

Thirty-nine COVID-19 cases and one death have been confirmed in Taiwan. Seventeen of these patients were infected by family members or in hospital wards, emphasizing how COVID-19 is mostly spread by close contact. We examined how hospital have responded to COVID-19, including their implementation of patient route control, outdoor clinics, hospital visit restrictions and ward and staff modifications. We also studied the public’s use of face masks in response to COVID-19. These strategies may reduce the spread of COVID-19 in other countries.

Conclusion

The emergence and spread of COVID-19 is a threat to health worldwide. Taiwan has reported lower infected cases and its strategies may contribute to further disease prevention and control.

Authors: Ripoll Karen , Carrillo Sonia , Gómez Yvonne ,   Universidad de Los Andes, Villada Johny ,   Universidad de Antioquía
Published: June 2020

The aim of this study was to evaluate the association between positive competences, such as emotion regulation, proactive coping and prosocial behavior, and Colombian adolescents' perception of their well-being and life satisfaction. Through a convenience sample, 930 7th and 9th grade adolescents attending 11 public and private schools in 2 main cities of Colombia answered to a set of scales that evaluate proactive coping, emotion regulation, prosocial behavior, perceived life satisfaction and well-being. Multiple linear regression analyses were conducted to evaluate models for adolescents' well-being and life satisfaction, with the positive competences taken as predictive variables. The model that showed the best fit and accounted for the greatest amount of variance in adolescents' well-being and life satisfaction included 2 dimensions of proactive coping (positive and social), emotion regulation and prosocial behavior. Recommendations for future research and the development of intervention programs to promote adolescents' well-being are presented.

Una gran proporción de las relaciones de pareja sufre problemas de infidelidad, impactándose sustancialmente la calidad de vida de sus miembros, sus familias y la sociedad. A pesar de que numerosos estudios han encontrado una relación directa entre el apego inseguro y la infidelidad, es menos lo que se sabe sobre las variables que podrían estar mediando dicha relación. Bajo este contexto, el objetivo del presente estudio fue esclarecer la relación entre el apego adulto y la infidelidad sexual, considerando 3 posibles mediadores: la satisfacción con la relación de pareja y la percepción de las consecuencias positivas y negativas de la infidelidad. Se obtuvo una muestra por conveniencia de 403 estudiantes de una universidad pública de Santo Domingo, República Dominicana, con edades comprendidas entre los 18 y 69 años (M = 28,05, DE = 8,69). El apego adulto se midió con el instrumento Experiencias en Relaciones Cercanas, la satisfacción con la relación de pareja, con el Índice de Satisfacción de Parejas y la infidelidad sexual y las consecuencias positivas y negativas de la infidelidad, mediante el Inventario Multidimensional de Infidelidad, Los resultados indicaron que tanto el apego evitativo como ansioso correlacionaron directamente con la infidelidad sexual y que esta relación estuvo mediada en gran medida, de acuerdo a un modelo de análisis de rutas con bootstraping, por la satisfacción con la relación de pareja y las consecuencias positivas de la infidelidad. Estos resultados son examinados a partir de la teoría del apego y se proponen líneas futuras de investigación.

Published: June 2020

Kachia Local Government Area (LGA) is located at the southern part of Kaduna State, Nigeria. Quantitative and qualitative appraisals were carried out in order to have proper understanding of the aquifer system and ensure sustainable development by using geophysical, geological and pumping test data obtained from 32 producing boreholes across the entire LGA. Hydraulic conductivity, transmissivity and storativity values were computed, piezometric surface map and the basement relief map were prepared, geoelectric layer characteristics were delineated and two geological profile sections were constructed. The hydraulic conductivity values were found to range from 0.021 m/day at Walijo to 1.391 m/day at Iddah-Hanya with an average of 0.42 m/day. The transmissivity values ranged between 0.90 m²/day at Walijo to 25.37m²/day at Iddah-Hanya, with average value of 6.31 m²/day. Storativity values were lowest at Walijo with a value of 89.42 and highest at Iddah-Hanya having a value of 2877 with an average of 929.82. The lowest values of these three aquifer constants were observed to converge at Walijo at the extreme eastern part and they all peaked at Iddah Hanya on the western border of the study area. The piezometric surface contour map showed that static water level is generally deeper around the central part of the study area than at the southern and western parts. The basement relief map revealed that the depth to Basement rock is generally deeper at the central part than at the eastern, western and southern boundaries of the study area. Three-layer geoelectric horizons delineated agreed with the drilled sections. The two profile sections 1 and 2 suggested that the weathered layer constituted the major aquiferous unit, and it occurred within a depth of 1 m to as much as 35 m, except Kurmin-Sara with 80 m thickness. Groundwater prospecting can therefore be targeted to an approximately uniform regolith thickness across the entire study area.

Published: June 2020

The present study applied different statistical tools to determine abused and neglected status among elderly people of the Chitmahal areas of Bangladesh. Also investigated the factors that associated with abuse and neglected status. The present study is conducted at the former Chitmahal areas which are situated at four districts namely Lalmonirhat, Nilphamari, Kurigram and Panchagar in Northern Bangladesh. Among the total 141 Chitmahal areas, 36 Chitmahal areas are randomly selected for the study area and finally 270 elder families are included for this research purpose. Information about socio-demographic, economic, health status, abuse and neglected related characteristics of the respondents and their family members was collected by using a pre-tested structured questionnaire. Elder abuse and neglect is the widespread issue in the world. This study found that most of the elder people (71.5%) of Chitmahal areas were neglected and abused in any form. Separately they were abused by psychologically (50.4%), financially (60.4), treatment related neglect (40%) and physically (1.5%). Most of them were neglected by their family members which mostly happened in the families with low monthly income and expenditure. The factors like age of elder people, educational level, previous and present occupation of respondents, ownership of house, monthly family income and expenditure, people’s participation in social occasion are the common significant factors for different types of abuse and neglected status of the aging peoples of Chitmahal areas in Bangladesh. The overall findings found a close relationship of abused and neglected status of the elderly peoples with their socio-economic, educational background and family economic condition. This information needs to be properly utilized in developing suitable social and motivational programs for elder families in the Chitmahal areas and countrywide by NGO’s and Government initiatives.

The experiment was conducted at Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from October 2016 to April 2017. The experiment was conducted to assess the effect of two factors, for example; I, two levels of foliar spray of boron as:100 ppm boric acid (B1) and 200 ppm boric acid (B2) in relation to a control and II, three different tomato cultivars/lines as: L1: Exotic Tomato Line-1, L2: Exotic Tomato Line-2, L3: BARI Tomato-15. The two factorial experiments were laid out in Randomized Complete Block Design with three replications. Fruit setting (56.73%), yield (64.89 t/ha) and total soluble solid (TSS) (4.3%) were considerably higher in B1 and low in B2. Whereas, significantly higher yield (79.87 t/ha) was recorded in L3 in in comparison to L1. Considering quality parameters, Vitamin C (20 mg) was the highest in L3 whereas TSS (4.58%) was the highest in L1. In interaction effect, the highest yield (85 t/ha) was obtained from B1L3 and the lowest (31.23 t/ha) in B2L1. The present study suggest to cultivate BARI Tomato-15, but other two exotic lines adapted well and showed good performance in terms of yield and quality parameters.

Published: June 2020

Wheat seed samples were collected from ten unions of sadar upazilla of Thakurgaon district in wheat growing season of 2011. Seeds were tested by blotter method at Seed Pathology Center (SPC), Bangladesh Agricultural University, Mymensingh during the months April to November 2011 for recording and identifying the seed-borne fungi associated with wheat seeds. The health status of 20 seed samples were determined whereas five genera fungi were identified from a total of six fungus. The fungi were Bipolaris sorokiniana, Alternaria tenuis, Fusarium spp, Penicillium sp, Aspergillus flavus and Aspergillus niger. Prevalence of the total as well as the individual seed-borne fungal infections that were recorded varied significantly with respect to wheat varieties and sources of seed collection. Seed samples collected from Jagonathpur and Gorea unions of sadar upazilla showed highest percentage of seed-borne infection compared to the samples collection from other unions for both varieties. The seed-borne fungal infection in Hazar-8 and Satabdi collected from other unions showed lowest percentage of seed-borne fungal infection than that of Jagonathpur and Gorea unions. Seed germination also varied significantly depending on the varieties and the seed sources and a positive correlation between seed germination and seed-borne fungal infections were observed. Three seed treating agents viz., neem leaf extract 1:2, hot water and Provax were evaluated for controlling seed-borne fungi associated with wheat seeds. Among the seed treating agents, Provax was found superior to reduce the seed-borne infection of wheat. The results also showed that neem leaf extract at 1:2 dilutions was observed to be the most effective in reducing seed-borne fungi with highest percentage of germination followed by hot water treatment.

Published: June 2020

One of the major environmental problem is the long-term changes in the Earth’s climate. In this study, the variation of solar radiation for Akwanga zone, Nasarawa State, Nigeria were determined. Twelve locations were carefully selected where there is no sunshine and wind obstruction. Three 12V, 5W Solar panels (poly) were used and a three-hour daily measurement interval (12.00 pm to 3.00 pm) was made using the Secondary Standard Pyranometer placed on the top of the panels. Angstrom-Prescott Regression Equation was used to estimate the output. The continuity in the assembled system was measured using an Avometer. The result revealed that the highest monthly average daily global solar radiation was observed in the month of April (25.2 MJ/m2) followed by June (22.94 MJ/m2), and march (22.42 MJ/m2), while the lowest was observed in the month of August (12.04 MJ/m2) followed by July (13.57 MJ/m2), and September (14.26 MJ/m2) in the locations selected. The solar radiation intensity was found to range from 156.44 W/m2 to 293.84 W/m2 with the mean value of 220.04 W/m2. The highest total global solar radiation value of 25.2MJ/m2 was observed in April while the lowest value of 12.04 MJ/m2 was observed in October. The extraterrestrial solar radiation were found to range from 16.72 MJ/m2 in March to 29.90 MJ/m2 in April with average value of 22.89MJ/m2. The atmospheric transmission coefficient over the year is found to range from 0.5 in July and October to 1.3 in June and October. The investigation reveal that there is bright sun shine in the study area which confirms high atmospheric transmission coefficient or clearness index throughout the year in this study.
Effects of Chronic Use of Herbicides on Soil Physicochemical and Microbiological Characteristics
Authors: Tudararo-Aherobo L. E. , Ataikiru T. L.
Published: June 2020

Introduction: Herbicide application is a vital strategy of weed control. The effects of these chemicals on the non-target soil microorganisms are very intense; have adverse impact on physicochemical parameters of the soil, which in turn affect soil fertility and plant growth.

Research Gap: There are insufficient literatures on extensive monitoring of the effects of prolonged herbicides use. Existing literatures concerning analysis of effect of prolonged herbicides application on soil are not comprehensive with respect to number of soil characteristics analyzed.

Aim: This study assessed the effects of Atrazine and Glyphosate on physicochemical properties and microbial population of carrot and maize farm soils, exposed to prolonged use at Songhai Delta.

Place and Duration of Study: The study was conducted in Songhai Delta farms and the Department of Environmental Management and Toxicology, Federal University of Petroleum Resources, Effurun, from April to July, 2019.

Methodology: These pesticides were applied according to the manufacturers’ instructions at sublethal concentrations. Their effects on soil pH, cation exchange capacity, total organic carbon, nitrates, phosphates, sulphates and microbial populations at two depths (0-15 and 15-30 cm) were assessed using standard methods. Microbial counts were carried out for total heterotrophic bacteria and fungi using the pour plate method.

Results: There were variations in the different properties of the carrot and maize farm soils. Soil pH was higher in maize farm (5.91±0.10) than in carrot farm (5.88±0.06) at the depth of 15-30 cm. The pH, total organic carbon, nitrate content had no significant difference while phosphate and microbial counts were significantly different at P=.05.

Conclusion: This assessment has shown that the herbicides had no influence on pH, total organic carbon, nitrate but a negative one on bacterial and fungal populations with prolonged use. A modification in physicochemical and microbiological characteristics of soil could be used to predict the fertility and health status of soils.
Intensional Transitive Verbs
Authors: Schwarz Florian
Published: June 2020

This chapter reviews the phenomenon of intensional transitive verbs such aslook for,need, andwant, as well as its main analyses proposed in the literature. The verbs in question are special in that they relate to their object argument in ways that are different from regular transitive verbs. Key empirical reflexes of this are presented in section 2, most prominently concerning nonspecificity, failure of extensional substitution, and lack of existential import. Next, the three main theoretical analyses are reviewed, which respectively propose that these verbs take covert clausal complements, intensional quantifiers, or properties as their arguments. Finally, more intricate empirical points are considered in light of their relationship to the various proposals, and the possible differences between types of intensional transitive verbs are discussed.
New insights into the formation and duration of flashbulb memories: Evidence from medical diagnosis memories
Authors: May Cynthia P. , Dein Anthony , Ford Jaclyn

Flashbulb memories are vivid and salient memories for the moment one hears about a surprising, emotional, and significant event. The current research examined flashbulb memories for a loved one's medical diagnosis, focusing on individual and situational factors associated with memory development and endurance over time. An online survey collected memory narratives and subjective ratings from 309 mothers who received a diagnosis of Down syndrome for their child. Time since diagnosis ranged from 1 month to 52 years. Using two independent measures, the Flashbulb Memory Checklist and the Autobiographical Memory Questionnaire, we found that a majority of diagnosis memories qualified as flashbulb memories, even 20 years or more after the event. Importantly, support from the medical staff at diagnosis emerged as a critical variable related to flashbulb memory development and the persistence of these flashbulb memories over time.

This article deals with the problem of robust output feedback control design for a class of switched systems with uncertainties and random time‐varying delay. Our purpose is focused on designing a full order dynamic output feedback controller and an appropriate switching rule to ensure the exponential mean square stability of the resulting closed‐loop switching system with an l2−l∞ performance level. The appealing aspects of the proposed control scheme include: (a) the development of LMI based delay‐dependent sufficient conditions for the exponential stability analysis of the stochastic hybrid systems using the appropriate choice of the augmented Lyapunov–Krasovskii functional, the partitioning technique and the average dwell time, (b) conservatism reduction of the unified design conditions, and (c) the controller designed exhibiting robustness with l2−l∞ performance against uncertainties and external disturbance. Finally, representative examples are given to demonstrate the validity and the merit of the proposed design technique.

The coupling of nickel‐rich LiNi0.8Mn0.1Co0.1O2 (NMC811) cathodes with high‐capacity silicon–graphite (Si–Gr) anodes is one promising route to further increase the energy density of lithium‐ion batteries. Practically, however, the cycle life of such cells is seriously hindered due to continuous electrolyte degradation on the surfaces of both electrodes. In this study, tris(trimethylsilyl) phosphite (TMSPi) is introduced as an electrolyte additive to improve the electrochemical performance of the NMC811/Si–Gr full cells through formation of protective surface layers at the electrode/electrolyte interfaces. This is thought to prevent the surface fluorination of the active materials and enhance interfacial stability. Notably, TMSPi is shown to significantly reduce the overpotential and operando X‐ray diffraction (XRD) confirms that an irreversible “two‐phase” transition reaction caused by the formed adventitious Li2CO3 layer on the surface of NMC811 can transfer to a solid‐solution reaction mechanism with TMSPi‐added electrolyte. Moreover, influences of TMSPi on the cathode electrolyte interphase (CEI) on the NMC811 and solid electrolyte interphase (SEI) on the Si–Gr are systematically investigated by electron microscopy and synchrotron‐based X‐ray photoelectron spectroscopy which allows for the nondestructive depth‐profiling analysis of chemical compositions and oxidation states close to the electrode surfaces.

Published: June 2020

Breast cancer stem cells (BCSCs) are responsible for resistance to chemotherapy, high degree of metastasis, and poor prognosis, especially in triple‐negative breast cancer (TNBC). The CD24lowCD44high and high aldehyde dehydrogenase 1 (ALDH1) cell subpopulation (CD24lowCD44high ALDH1+) exhibit very high tumor initiating capacity. In the current study, the upregulated genes are analyzed in both CD24lowCD44high and ALDH1+ cell populations at single‐cell resolution, and a highly expressed membrane protein, SGCE, is identified in both BCSC populations. Further results show that SGCE depletion reduces BCSC self‐renewal, chemoresistance, and metastasis both in vitro and in vivo, partially through affecting the accumulation of extracellular matrix (ECM). For the underlying mechanism, SGCE functions as a sponge molecule for the interaction between epidermal growth factor receptor (EGFR) and its E3 ubiquitination ligase (c‐Cbl), and thus inhibits EGFR lysosomal degradation to stabilize the EGFR protein. SGCE knockdown promotes sensitivity to EGFR tyrosine kinase inhibitors (TKIs), providing new clues for deciphering the current failure of targeting EGFR in clinical trials and highlighting a novel candidate for BCSC stemness regulation.
The Parallel Encounter: An Alternative to the Traditional Serial Trainee–Attending Patient Evaluation Model
Authors: Andre Hayley E. , Daniel Michelle , Haas Mary R. C.
Published: June 2020

Background

The emergency department environment requires the clinician‐educator to use adaptive teaching strategies to balance education with efficiency and patient care. Recently, alternative approaches to the traditional serial trainee–attending patient evaluation model have emerged in the literature.

Methods

The parallel encounter involves the attending physician and resident seeing the patient independently. Instead of the trainee delivering a traditional oral case presentation, the trainee does not present the history and examination to the attending physician. Rather, the attending and trainee come together following their independent evaluations to jointly discuss and formulate the assessment and plan.

Results

The parallel encounter has the potential to enhance the teaching encounter by emphasizing clinical reasoning, reduce cognitive bias by integrating two independent assessments of the same patient, increase attending workflow flexibility and efficiency, and improve patient satisfaction and outcomes by reducing time to initial provider contact. The attending must be mindful of protecting resident autonomy. This model tends to work better for more senior learners.

Conclusions

The parallel encounter represents a novel approach to the traditional serial trainee–attending patient evaluation model that may enhance the teaching encounter and improve patient care.
Sweetpotato leaf curl virus decreased storage root yield and quality of edible sweetpotato in China

Sweetpotato leaf curl virus (SPLCV) causes leaf curl symptoms in sweetpotato [Ipomoea batatas (L.) Lam]. These symptoms disappear under high temperature. Previous studies have shown that SPCLV reduces storage root yield in sweetpotato. However, knowledge of SPLCV's effect on root quality is limited. In this study, we surveyed the effect of SPLCV on storage root yield and quality in edible sweetpotato. Quantitative real‐time reverse transcriptase–polymerase chain reaction and leaf paraffin section results showed that the SPLCV mRNA level and the distribution density of spongy mesophyll cells in SPLCV‐infected plants were significantly higher than in healthy control plants (CK). Leaf net photosynthetic rate, vine length, and storage root yield were reduced in SPLCV‐infected plants during the growing period, and the shoot/root ratio was significantly increased compared with CK. Additionally, root abscisic acid, auxin, and zeatin riboside contents under SPLCV infection were higher than the CK, whereas root gibberellic acid content was lower. Root dry matter, starch, and carotenoid contents were lower in the infected plants than in the CK. Moreover, SPLCV‐infected plants showed reduced expression of starch and carotenoid metabolitic genes, such as ADP‐glucose pyrophosphorylase‐ß, granule‐bound starch synthase I, starch branching enzyme I and II, and carotenoid isomerase, and increased expression of α‐amylase, ß‐carotene hydroxylase, and zeaxanthin epoxidase. These results suggest that sweetpotato infected by SPLCV had decreased storage root yield and decreased starch and carotenoid contents through reducing photosynthetic capacity, regulating starch and carotenoid degradation, and changing endogenous hormone contents. Therefore, effective management should be taken to prevent SPLCV epidemics during sweetpotato production.

Twin‐row planting in soybean (Glycine max L.) has been proposed for optimizing resource use and seed yield. Experiments were conducted in 2018 and 2019 on a Dundee silt loam to assess soybean seed yield and irrigation water use efficiency (IWUE) in response to single‐row (SR) and twin‐row (TR) planting geometries under rainfed (RF), all row or full irrigation (FI), and alternate row or half irrigations (HI). Averaged across two crop years and three irrigation regimes, TR enhanced seed yield by 13% over SR (4.5 vs. 4.0 Mg ha−1). The final plant stands established in the FI, HI, and RF under TR were 32, 33, and 31 plants m−2, whereas 30, 31, and 27 plants m−2 were established under SR. Under both SR and TR, irrigations produced a higher number of pods per plant than of RF. Averaged across crop years, yields in the irrigation–planting geometry combinations were 4.8 Mg ha−1 in FI‐TR, 4.7 in Mg ha−1 in HI‐TR, 4.2 Mg ha−1 in FI‐SR, 4.1 Mg ha−1 each in RF‐TR and HI‐SR, and 3.6 Mg ha−1 in RF‐SR. The HI‐TR combination had the highest IWUE of about 0.0063 Mg ha−1 mm−1 of water, followed by HI‐SR with 0.0053 Mg ha−1 mm−1. The seed yield in FI‐TR was not significantly higher than that of HI‐TR. Thus, conversion from FI‐TR to HI‐TR can save half the amount of irrigation without compromising yield or economic returns. Conversion from SR to TR is profitable regardless of the irrigations.

Published: June 2020

Background

Complications in survivors after typical hanging have not been well characterized because of the high mortality rate.

Case Presentation

We present a patient with bilateral vocal cord paralysis following typical hanging. A 39‐year‐old man with depression attempted suicide by hanging. He was in a coma and was transported to our hospital. Emergency endotracheal intubation was carried out. After 10 days of mechanical ventilation, he was extubated. After extubation, his voice was hoarse and stridor was heard. Vocal cord paralysis became apparent by laryngeal fiberscopy, and a tracheotomy was carried out. It resolved gradually 2 months after injury without surgery or drug treatment.

Conclusion

Although vocal cord paralysis after typical hanging is rare, there is a need for adequate assessment of the airways in survivors of typical hanging as a differential diagnosis of airway edema after extubation.
