Pension communication, knowledge, and behaviour
Authors: Debets Steven , Prast Henriette , Rossi Mariacristina , van Soest Arthur
Published: September 2020

Many recent pension reforms require individuals to make more decisions on supplementary savings, investment choices, etc. Governments and the pension industry try to assist individuals through pension communication but little is known about the effectiveness of such policies. This paper uses Dutch longitudinal data to analyse the causal links between communication, pension knowledge, and conscious pension decision-making. A robust finding is that pension knowledge has a positive causal effect on active pension decision-making. Providing an annual pension statement might have a small positive effect on pension knowledge, but this result is sensitive to the identifying assumptions.

Objective

Few studies have examined burnout in psychosocial oncology clinicians. The aim of this systematic review was to summarize what is known about the prevalence and severity of burnout in psychosocial clinicians who work in oncology settings and the factors that are believed to contribute or protect against it.

Method

Articles on burnout (including compassion fatigue and secondary trauma) in psychosocial oncology clinicians were identified by searching PubMed/MEDLINE, EMBASE, PsycINFO, the Cumulative Index to Nursing and Allied Health Literature, and the Web of Science Core Collection.

Results

Thirty-eight articles were reviewed at the full-text level, and of those, nine met study inclusion criteria. All were published between 2004 and 2018 and included data from 678 psychosocial clinicians. Quality assessment revealed relatively low risk of bias and high methodological quality. Study composition and sample size varied greatly, and the majority of clinicians were aged between 40 and 59 years. Across studies, 10 different measures were used to assess burnout, secondary traumatic stress, and compassion fatigue, in addition to factors that might impact burnout, including work engagement, meaning, and moral distress. When compared with other medical professionals, psychosocial oncology clinicians endorsed lower levels of burnout.

Significance of results

This systematic review suggests that psychosocial clinicians are not at increased risk of burnout compared with other health care professionals working in oncology or in mental health. Although the data are quite limited, several factors appear to be associated with less burnout in psychosocial clinicians, including exposure to patient recovery, discussing traumas, less moral distress, and finding meaning in their work. More research using standardized measures of burnout with larger samples of clinicians is needed to examine both prevalence rates and how the experience of burnout changes over time. By virtue of their training, psychosocial clinicians are well placed to support each other and their nursing and medical colleagues.
Anthropocene Politics
Authors: Battistoni Alyssa
Published: September 2020

Those for whom the term “Anthropocene” tends to evoke academic faddishness may be surprised to realize that the discourse about it is now two decades old. The term was first proposed in a 2000 paper by the atmospheric chemist Paul Crutzen and biologist Eugene Stoermer to describe the geological epoch in which human activity has come to shape the Earth itself. Since then, the concept has generated a vast amount of scholarly conversation and a wide range of interpretations, often concerning the start date of this new era: Did the “age of man” begin with the use of fire? The development of settled agriculture? The rise of capitalism? European settlement of the Americas? And so on. Although these debates have raged across the humanities and sciences for years, political theorists have largely kept their distance. As the climate crisis worsens, however, many may now be looking to play catch-up. If so, each of the three books under review here holds out the promise of helping us understand the theoretical implications of this epochal transformation.
Validation of a Portuguese Version of the Aspiration Index for Adolescents (AI)
Authors: Costa Mónica , Matos Paula Mena , Mota Catarina Pinheiro
Published: September 2020

Intrinsic and extrinsic types of motivation have been widely studied, and their importance on both developmental and educational practices has led to the development of assessment tools. The Aspiration Index scale (AI; Grouzet et al., 2005), which was developed to measure people`s life aspirations, was translated and validated into Portuguese. A sample of 1,359 adolescents, age ranged from 12 to 18 years-old, participated in the present study. Results showed that a factor structure with the eleven subscales of the AI does not fit the data. However we gathered support for a three-factor structure that organized the items in terms of whether aspirations are intrinsically, extrinsically or self-transcendent oriented. Internal consistency and temporal stability yielded good results. The predictive and criterion validities were demonstrated by significant associations with theoretically supported measures of satisfaction with life and father and mother attachment. The multi-group confirmatory factor analysis showed that this structure was invariant across gender. These results suggest that the AI is a reliable measure to assess different types of life aspirations and can be used in future research with adolescents in Portugal.
Measurement Invariance of Three Brief Measures of Rumination in Young	Adults With and Without a History of Self-Injury

Published: September 2020

Abstract. Rumination is central to understanding the onset and maintenance of non-suicidal self-injury. Yet, no study has evaluated whether reported differences in rumination between people with and without a history of self-injury represent genuine group differences. The present study reports an investigation into the measurement invariance of three common measures of rumination in university students with and without a history of self-injury (total N = 1,519). Results revealed configural invariance for the Ruminative Responses Scale (RRS), the Ruminative Thought Style Questionnaire (RTSQ), and the Repetitive Thinking Questionnaire (RTQ). Additionally, the RTSQ and RTQ supported metric invariance, while the RRS supported partial metric invariance. Further, the RTQ demonstrated partial scalar invariance while the RTSQ demonstrated full scalar invariance. The current findings suggest that observed differences using the RTSQ and RTQ reflect genuine differences in rumination between people with and without a history of self-injury, while researchers using the RRS are advised to account for differential item functioning.

Published: September 2020

Sperm, which have a vital role in sexual reproduction in the animal kingdom, can display heteromorphism in some species. The regulation of sperm dichotomy remains a longstanding puzzle even though the phenomenon has been widely documented for over a century. Here we use Bombyx mori as a model to study a form of sperm dimorphism (eupyrene and apyrene sperm), which is nearly universal among Lepidoptera. We demonstrate that B. mori Sex-lethal (BmSxl) is crucial for apyrene sperm development, and that B. mori poly(A)-specific ribonuclease-like domain-containing 1 (BmPnldc1) is required for eupyrene sperm development. BmSXL is distributed in the nuclei and cytoplasm of somatic cyst cells in a mesh-like pattern and in the cytoplasm of germ cells enclosed in spermatocysts and sperm bundles. Cytological analyses of dimorphic sperm in BmSxl mutants (∆BmSxl) showed deficient apyrene sperm with abnormal nuclei, as well as loss of motility associated with malformed mitochondrial derivatives. We define the crucial function of apyrene sperm in the process of fertilization as assisting the migration of eupyrene spermatozoa from bursa copulatrix to spermatheca. By contrast, BmPnldc1 deficiency (∆BmPnldc1) caused eupyrene sperm abnormalities and impaired the release of eupyrene sperm bundles during spermiation. Although apyrene or eupyrene sperm defects impaired fertility of the mutated males, double copulation of a wild-type female with ∆BmSxl and ∆BmPnldc1 males could rescue the sterility phenotypes induced by single copulation with either gene-deficient male. Our findings demonstrate the crucial functions of BmSxl and BmPnldc1 in the development of sperm dimorphism and the indispensable roles of nonfertile apyrene sperm in fertilization.

In yeast and animal cells, mitochondrial disturbances resulting from imbalances in the respiratory chain require malate dehydrogenase (MDH) activities for re-directing fluxes of reducing equivalents. In plants, in addition to mitochondria, plastids use malate valves to counterbalance and maintain redox-homeostasis. Arabidopsis expresses three cytosolic MDH isoforms, namely cyMDH1, cyMDH2, and cyMDH3, the latter possessing an N-terminal extension carrying a unique cysteine residue C2. In this study, redox-effects on activity and structure of all three cyMDH isoforms were analyzed in vitro. cyMDH1 and cyMDH2 were reversibly inactivated by diamide treatment, accompanied by dimerization via disulfide-bridge formation. In contrast, cyMDH3 forms dimers and higher oligomers upon oxidation, but its low specific activity is redox-independent. In the presence of glutathione, cyMDH1 and cyMDH2 are protected from dimerization and inactivation. In contrast, cyMDH3 still dimerizes but does not form oligomers any longer. From analyses of single and double cysteine mutants and structural modeling of cyMDH3, we conclude that the presence of C2 and C336 allows for multiple cross-links in the higher molecular mass complexes comprising disulfides within the dimer as well as between monomers of two different dimers. Furthermore, nuclear localization of cyMDH isoforms was significantly increased under oxidizing conditions in isolated Arabidopsis protoplasts, in particular of isoform cyMDH3. The unique cyMDH3 C2–C2-linked dimer is, therefore, a good candidate as a redox-sensor taking over moonlighting functions upon disturbances of energy metabolism, as shown previously for the glycolytic enzyme glyceraldehyde 3-phosphate dehydrogenase (GAPDH) where oxidative modification of the sensitive catalytic cysteine residues induces nuclear translocation.
Architectural RNA in chromatin organization
Authors: Thakur Jitendra , Henikoff Steven
Published: September 2020

RNA plays a well-established architectural role in the formation of membraneless interchromatin nuclear bodies. However, a less well-known role of RNA is in organizing chromatin, whereby specific RNAs have been found to recruit chromatin modifier proteins. Whether or not RNA can act as an architectural molecule for chromatin remains unclear, partly because dissecting the architectural role of RNA from its regulatory role remains challenging. Studies that have addressed RNA's architectural role in chromatin organization rely on in situ RNA depletion using Ribonuclease A (RNase A) and suggest that RNA plays a major direct architectural role in chromatin organization. In this review, we will discuss these findings, candidate chromatin architectural long non-coding RNAs and possible mechanisms by which RNA, along with RNA binding proteins might be mediating chromatin organization.
Metabolic engineering for the production of butanol, a potential advanced biofuel, from renewable resources
Authors: Zhao Chunhua , Zhang Yanping , Li Yin
Published: September 2020

Butanol is an important chemical and potential fuel. For more than 100 years, acetone-butanol-ethanol (ABE) fermentation of Clostridium strains has been the most successful process for biological butanol production. In recent years, other microbes have been engineered to produce butanol as well, among which Escherichia coli was the best one. Considering the crude oil price fluctuation, minimizing the cost of butanol production is of highest priority for its industrial application. Therefore, using cheaper feedstocks instead of pure sugars is an important project. In this review, we summarized butanol production from different renewable resources, such as industrial and food waste, lignocellulosic biomass, syngas and other renewable resources. This review will present the current progress in this field and provide insights for further engineering efforts on renewable butanol production.
A Bayesian-Inspired Item Response Theory–Based Framework to Produce Very Short Versions of MacArthur–Bates Communicative Development Inventories
Authors: Chai Jun Ho , Lo Chang Huan , Mayor Julien
Published: September 2020

Purpose

This study introduces a framework to produce very short versions of the MacArthur–Bates Communicative Development Inventories (CDIs) by combining the Bayesian-inspired approach introduced by Mayor and Mani (2019) with an item response theory–based computerized adaptive testing that adapts to the ability of each child, in line with Makransky et al. (2016).

Method

We evaluated the performance of our approach—dynamically selecting maximally informative words from the CDI and combining parental response with prior vocabulary data—by conducting real-data simulations using four CDI versions having varying sample sizes on Wordbank—the online repository of digitalized CDIs: American English (a very large data set), Danish (a large data set), Beijing Mandarin (a medium-sized data set), and Italian (a small data set).

Results

Real-data simulations revealed that correlations exceeding .95 with full CDI administrations were reached with as few as 15 test items, with high levels of reliability, even when languages (e.g., Italian) possessed few digitalized administrations on Wordbank.

Conclusions

The current approach establishes a generic framework that produces very short (less than 20 items) adaptive early vocabulary assessments—hence considerably reducing their administration time. This approach appears to be robust even when CDIs have smaller samples in online repositories, for example, with around 50 samples per month-age.
Regular quantisation with hysteresis: a new sampling strategy for event‐based PID control systems
Authors: Miguel‐Escrig Oscar , Romero‐Pérez Julio‐Ariel
Published: September 2020

In this study, a new sampling strategy for networked control systems, called regular quantification with hysteresis (RQH), is proposed. This alternative presents some benefits with respect to symmetric‐send‐on‐delta sampling, which is one of the most used strategies in the event‐based proportional–integral–derivative (PID) control loops. The behaviour of the RQH is defined by two parameters, the signal quantification and hysteresis, whose effect on the overall system performance is studied and guidelines about its choice are given in terms of noise measurement and steady‐state error. The limit cycle oscillations that could be induced by this sampling strategy are studied and new robustness measures to avoid them are proposed based on the describing function approach. The suitability of some tuning rules for continuous PI when applied to control systems with a RQH sampling is evaluated using the proposed measures. The results show that these tuning rules can be applied under certain conditions.

There are plenty of biomass resources in Thailand such as agricultural residues from plantations and industrial or woody processes. Biomass in the form of a pellet has more energy density than the original form moreover it is easier to handle and has a higher strength. This study selected woody parts from commonly found trees in Southern Thailand, fuel pellets were made to examine the physical properties and microstructure. Para-rubber (Hevea brasiliensisMuell. Arg.) sawdust and the branches and leaves of She Oak (Casuarina Equisetifolia) and the Cajuput tree (Melaleuca Cajuputi) were collected from the local area to make pellets by a single unit pellet mill at 130oC and 450 psi of compression temperature and pressure, respectively. The physical properties were characterized via pellet density, moisture content, heating value and compressive strength. Moreover, the microstructure of cross section area of pellet samples from the scanning electron microscope (SEM) pictures were proposed to observe the bonding mechanism. The results show that the different raw material provided different properties. The highest pellet strength, density and heating value was achieved from Cajuput leaves.

This research aimed to study the combination of NIR spectroscopy and machine learning for monitoring chilli sauce adulterated with papaya smoothie. The chilli sauce was produced by the famous community enterprise of chilli sauce processing in Thailand. The ingredients of the chilli sauce consisted of 45% chilli, 25% sugar, 20% garlic, 5% vinegar, and 5% salt. The chilli sauce sample was mixed with ripened papaya (Khaek Dam variety) smoothie with 9 levels from 10 to 90 %w/w. The NIR spectra of pure chilli sauce, papaya smoothie and 9 adulterated chilli sauce samples were recorded using FT-NIR spectrometer in the wavenumber range of 12500 and 4000 cm-1. Three machine learning algorithms were applied to develop a model for monitoring adulterated chilli sauce, including partial least squares regression (PLS), support vector machine (SVM), and backpropagation neural network (BPNN). All model presented performance of prediction in the validation set with R2al = 0.99 while RMSEP of PLS, SVM and BPNN were 1.71, 2.18 and 3.27% w/w respectively. This finding indicated that NIR spectroscopy coupled with machine learning approaches were shown to be an alternative technique to monitor papaya smoothie adulterated in chilli sauce in the global food industry.

Authors: Chungcharoen Thatchapol , Onboon Pornpit , Sansiribhan Sansanee
Published: September 2020

The process complexity is the main problem for parboiled germinated rice (PGR) production. The PGR production using the new method (germinating and drying using hot air fluidized bed combined with halogen lamp) can decrease the complexity of process and also provided the good quality of PGR when comparing with PGR production using traditional method (germinating, steaming and drying using hot air fluidized bed). The new method provided the higher drying rate, leading to faster decrease of moisture content and higher increase of grain temperature. This caused the lower whiteness index. It also provided the lower degree of gelatinization. However, the percentage of head rice yield of PGR with new method was not significantly different when comparing with PGR production using traditional method. For Specific Energy Consumption (SEC), the PGR production using the new method provided the lower SEC value than PGR production using traditional method.

Authors: Wongsa Jittimon , Aichayawanich Sawanit
Published: September 2020

This research aimed to study effects of Chew-Kuk on physical properties of waxy rice starch gel. Sensory evaluation, color and textural profiles were determining criteria used to evaluate the waxy rice starch gel with added Chew-Kuk. The experimental results show that Chew-Kuk significantly affects color and texture of the waxy rice starch gel. Upon adding Chew-Kuk, waxy rice starch gel became yellowish green. Hardness, gumminess, and chewiness values of waxy rice starch gel with Chew-Kuk were decreased when Chew-Kuk: waxy rice starch ratios increased. Moreover, liking scores tended to be higher when adding more Chew-Kuk contents. Therefore, the suitable ratio between Chew-Kuk and waxy rice starch in this research is the highest ratio (Chew-Kuk: waxy rice starch equal to 20: 100).

This research aims to study the characteristic of paddy motion under the hot air pulse flow in the drying tube length 2 m by using the kinematics motion analysis. The equations of paddy motion are analyzed to evaluate the pattern of paddy motion, total distance that the paddy can travel through the drying tube and Reynolds number of paddy. Results found that Model I, II and III consume the paddy travel time of approximately 1.3, 5.0 and 2.2 s and give a total distance of 2.6, 2.7 and 2.5 m and they have maximum travel velocity of 4.12, 1.37 and 1.85 m/s respectively. When considering the Reynolds number, the models I, II and III give the most values from similar calculations with 1,837, 1,816 and 1,821 respectively. Based on various parameters from all of models, Model III was the closest characteristic of paddy motion to the actual movement in the system.

There are using meteorological data from 2012 - 2016 at Nakhon Ratchasima station. The case analysis shows the results of evapotranspiration are the potential of evaporation of plants each year. Abtew analysis gave higher monthly evapotranspiration results during the dry season than Morton CRAE, but with Abtew formulation gave lower monthly evapotranspiration results during the rainy season than that of the method. The results are 2 ways to use evapotranspiration for water management, which is to analyze the amount of evapotranspiration for use in irrigation systems in order to water for plants should use the form of Abtew form because it can be seen that during the dry season and the plant has a high evapotranspiration value. Form Morton CRAE should be used to assess the potential water use of plants that can be seen in the dry season, the evaporation of plants is also less because in the surrounding environment there isn’t water and has little moisture causing plants to use less water.

The algorithm has the characteristic that no approximations or complicate control logic are required in the basic Sequential Linear Programming (SLP) formulation as used by other SLP algorithms reported in the literature. Transmission loss minimization is used as the primary objective. A secondary feasibility improvement objective is used which results in better feasible solution in comparison with the loss minimization objective especially when the initial base case has over voltages. Modification in the proposed method to obtain the limited amount and limited movement of controller solution for real time application is also presented. The algorithm has been tested on Ward and Hale 6-Bus system.

Auscultation is still one of the most basic analytical tools used to determine the fetal heart’s functional state as well as the first fetal well-being measure. It is called fetal phonocardiography (fPCG) in its modern form. The technique of fPCG is passive and can be used to track long-term. Robust signal processing techniques are required to denoise the signals in order to improve the diagnostic capabilities of fPCG. A linear filter is used to eliminate distortion and interference from the fPCG signals through conventional denoising techniques. This paper searched for optimal configuration of the wavelet based denoising system. Based on the experimental results, can be conclude that the signal should be decomposed on six levels. From this it can be seen that the lowest MSE (mean square error) value is the use of coiflets three with SURE threshold algorithm with hard threshold parameters.
