Help-Seeking Tendencies and Subjective Well-Being: A Cross-Cultural Comparison of the United States and Japan

Help-seeking is commonly conceived as an instrumental behavior that improves people’s subjective well-being. However, most findings supporting a positive association between help-seeking and subjective well-being are observed in independence-preferring countries. Drawing from research demonstrating that the pathways to subjective well-being are culturally divergent, we posit that help-seeking tendencies may be detrimental to subjective well-being for members in interdependence-preferring countries where norms for preserving relational harmony and face concerns are prevalent. This study tested the moderating role of country in the relationship between help-seeking tendencies and subjective well-being using data from 5,068 American and Japanese participants. Results revealed that although help-seeking tendencies were associated with greater life satisfaction, higher positive affect, and lower negative affect among Americans, help-seeking tendencies were associated with poorer life satisfaction and lower positive affect among Japanese. We discuss the importance of adopting culturally sensitive perspectives when examining antecedents of subjective well-being.
Abiotic Factors from Different Ecuadorian Regions and Their Contribution to Antioxidant, Metabolomic and Organoleptic Quality of Theobroma cacao L. Beans, Variety “Arriba Nacional”

Fine flavor cocoa is a unique category of cocoa that produces almonds with high aromatic potential and several sensory benefits that make it different from the basic or ordinary cocoas. Ecuador is the world’s leader in the production and export of fine flavor cocoa, responsible for 63% of the world’s total production due to the commercialization of the Arriba Nacional variety, known to possess an intense aroma that is unique in the cocoa world market. Besides its organoleptic specificity, this variety represents a source of important bioactive compounds associated with both sensory and health properties. This study evaluates the influence of an abiotic factor, nutritional soil status, on the phytochemical composition (methylxantines and phenolic compounds), and antioxidant and sensory properties of Arriba variety cocoa beans originating from three different geographical regions of Ecuador. We used the Diagnosis and Recommendation Integrated System (DRIS), Folin–Ciocalteau, high-performance liquid chromatography (HPLC), ABTS free-radical-scavenging activity, the α, α-diphenyl-β-picrylhydrazyl free-radical-scavenging method (DPPH), and Ferric reducing antioxidant power (FRAP) analysis to reveal a significant correlation between Mn ions and total phenolic content, a positive implication of N in methylxanthine composition and antioxidant properties, and the importance of Ca, Mg, and K ions in increasing the flavonoid and anthocyanin content of raw cocoa beans. We showed that these nutritional elements can interfere with the nutraceutical and sensory properties of cocoa beans, as Cu, Mg, and K are correlated with anthocyaninic content, while Fe, Ca, P and Zn influenced the flavonoid content. We underline that the Arriba variety is suitable not only for the production of high-quality chocolate, but also for the increasing worldwide nutraceutical market, generating qualitative and competitive products.
Using ANN to study the gender effect on horizontal transmissibility to the head during whole-body vibration

In this article, an Artificial Neural Network (ANN) has been used to model the relationship between the gender of human subject to its response to whole-body vibration (WBV). To train, validate and test the model, an experiment was conducted on 20 female and 20 male subjects at different vibration frequencies in the range of 20 to 45 Hz. The response was measured by taking the ratio between the subject head’s horizontal acceleration to the platform’s vertical acceleration. The subjects’ body mass index, mass, height, gender, and age, and the excitation frequency were used as inputs to the ANN. The ANN model showed a good performance of 98.645% matching regression, and RMSE and MAE of 0.0128 and 0.0483, respectively.
Investigation in physicochemical characteristics of jujube (Ziziphus jujuba Mill.) extract cake

In spite of freshly eaten, Jujube (Ziziphus jujuba Mill.) might be dried or processed into confectionary recipes in cakes, as one of the important products in food industries. The experiment was conducted based on complete randomized design with three replications. Treatments were control and three levels of jujube extraction (2, 4, and 6 percent) which added to cake’s formulation and sampling in different time periods. In the present study, the process of baking was in four steps. First of all, dried jujube fruit was mixed with water and its brix was reached 15 using direct heat. In the second step, a final brix of 60 was obtained by rotary evaporator. Then, appropriate amounts of egg, sugar, yogurt, oil, 2, 4, or 6 % jujube extract was mixed using a blender. Finally, baking powder, flour, and vanilla were mixed and the mixture was placed in the oven set at 160 °C for 20 minutes. Physicochemical analysis showed that the cakes containing 4 and 6 % of jujube extract were the best treatments at all time periods. However, analyze of sensational test results revealed that especially panelists evaluations that 6 percentage extract sample was significantly different from the others.
A new stator resistance estimation method for high performance stator-flux oriented sensorless induction motor drives

This paper deals with a novel method for implementation of a sensorless stator flux oriented control (SFOC) of induction motor drive with stator resistance tuning. The rotor speed is determined by the difference between the synchronous angular frequency and the estimated slip angular frequency which is estimated from the measured and reference q-axis stator current. The stator resistance updating is based on the measured and reference d-axis stator current of an induction motor on d-q frame synchronously rotating with the stator flux vector. The proposed method for estimation of speed and stator resistance is based only on measurement of stator currents and DC-bus voltage. Digital simulation is carried out to show that the proposed method can overcome the problem of performance degradation due essentially to changes in stator resistance. Robust sensorless speed control at nominal, low and zero speeds is introduced, with load torque applied, in order to show the robustness of the proposed method. Experimental results for a 3 kW induction motor are presented and analyzed by using a dSpace system with DS1102 controller board based on the digital signal processor (DSP) TMS320C31.
Building Resilient Leadership

Covid-19 poses the greatest challenges for effective leadership in many years. Covid-19 undermines the deepest security we feelas humans and disables people’s capacity to work and create. This opinion piece argues that leaders should not merely hold on until Covid-19 passes, but rather learn the lessons Covid-19 wishes to teach us. In so doing, leaders become resilient to adversity and can facilitate the resilience of employees, teams, and organisations. This article addresses these lessons in relation to our common humanity, the centrality of relationships, the vital importance of spirituality, and the need for structure to enable productivity.
Factors Determining the Functional State of Cardiac Surgery Patients with Complicated Postoperative Period

The purpose of this work was to study the factors determining the functional state of cardiac surgery patients with a complicated postoperative period upon discharge from the hospital. This observational study included 60 patients who underwent cardiac surgery with a complicated postoperative course and with a prolonged intensive care unit stay of more than 72 h. We assessed handgrip and lower-extremity muscle strength and the six-minute walk test (6MWT) distance 3 days after the surgery and at discharge from the hospital. Some patients (53%) additionally underwent a course of neuromuscular electrostimulation (NMES). Two groups of patients were formed: first (6MWT distance at discharge of more than 300 m) and second groups (6MWT distance of 300 m or less). The patients of the second group had less lower-extremity muscle strength and handgrip strength on the third postoperative day, a longer aortic clamping time and a longer stay in the intensive care unit. Independent predictors of decreased exercise tolerance at discharge were body mass index, foot extensor strength and baseline 6MWT distance in the general group, duration of cardiopulmonary bypass in the NMES group and in the general group, and age in the NMES group. Thus, the muscle status on the third postoperative day was one of the independent factors associated with the 6MWT distance at discharge in the general group, but not in patients who received NMES. It is advisable to use these results in patients with complications after cardiac surgery with the use of NMES rehabilitation.
The Importance of Self-Leadership Strategies and Psychological Safety for Well-Being in the Context of Enforced Remote Work

This study examines the relationship between self-leadership strategies and occupational well-being and whether psychological safety has moderated these relationships in the context of enforced remote work caused by COVID-19. Altogether, 2493 higher education employees, most of whom were working entirely remotely due to the pandemic, responded to an electronic survey in May 2021. Hierarchical multiple linear regression analyses were conducted as the main method of analysis. The results showed that goal-oriented and well-being-related self-leadership strategies as well as psychological safety were positively related to meaningfulness of work and negatively to job burnout. Psychological safety moderated the relation between goal-oriented self-leadership strategies and meaningfulness of work. The study presents much-needed novel knowledge about self-leadership and psychological safety in the context of remote work and sheds light on the interrelatedness between self-leadership strategies, psychological safety, and occupational well-being. It presents a novel category of well-being-related self-leadership strategies and contributes to the measurement of both self-leadership and psychological safety. In order to both enable sufficient well-being and facilitate flourishing at work, it is imperative to support employees in learning and applying diverse self-leadership strategies as well as ensure psychological safety at workplace, especially in post-pandemic multi-locational work.
Helicopter Flight Control Law Design With and Without Rotor State Feedback

An HOC formulation to design pitch-roll flight control laws for hovering helicopters is presented. Adjustment of the weight functions in the formulation is relatively straightforward. The feedback performance is set by the crossover frequency, which can be directly adjusted through the sensitivity (I+KG)"1 weight function. The closedloop stability is controlled by the complementary sensitivity KG(I + KG)'1 weight function. The relative size of the dynamic gains is adjusted through the control (/ + KG)~1K weight function. A framework to use the H^ compensation is also presented that allows systematic compliance to the quantitative low-speed requirements of a modern combat rotorcraft handling qualities specification (ADS-33C). Using this HOC formulation, control law designs were developed to investigate the effect of using rotor state feedback. Two laws were developed for an articulated rotor helicopter math model in low-speed flight: a compensator using rigid-body measurements and one using body plus rotor state measurements. Both laws were designed with similar crossover frequencies, stability margins, and response types. The design without rotor state feedback has the potential to pass approximately twice as much noise to the actuators near the I/rev frequency as the design with rotor state feedback. Furthermore, the response of the controller without rotor state feedback was more sensitive to gain variations. Because of this sensitivity, the design without rotor state feedback, configured as a high-bandwidth rate response type, showed more high-frequency oscillation in roll.

Knowledge, attitude, and practice of labor analgesia in antenatal women in India: An observational study

Background: The concept of labor analgesia is widely unknown to the antenatal women and parturients in the Indian medical setup. Aims: The aim of this study was to assess the knowledge, attitude, and practice of labor analgesia in antenatal women visiting the antenatal clinic in a tertiary care hospital. Methodology: One hundred twenty women in the antenatal period between the age group of 18 and 40 years attending the antenatal clinic were included in the study. A Google form-based questionnaire was used to collect data. Statistical Analysis: Ordinal and nominal data were presented as numbers and percentages. Bar diagrams and pie charts were used for graphical representation. Results: Twenty-one (17.5%) respondents, out of 120, were aware of labor analgesia. Among the rest 99, 13 participants did not have knowledge nor they wanted to gather information further. Out of 86 unaware respondents, 62 (72.1%) were interested in acquiring the knowledge of labor analgesia and rather would be comfortable if the treating obstetrician imparts the information; 46 (53.5%) of them wanted the information to be imparted during the obstetric consultation sessions and 10 (11.6%) respondents considered the best time for gathering awareness for labor analgesia at, or after the onset of labor pain. The major concerns of the respondents for labor analgesia were the safety of their health and the effect on the baby. Conclusions: Awareness of labor analgesia in Indian antenatal women is low. The treating obstetrician should impart knowledge regarding labor analgesia in the pre- and antenatal period which should be supplemented with more emphasis during the prelabor period.
Mechanosynthesis of phosphonocinnamic esters through solvent-free Horner-Wadsworth-Emmons reaction

Abstract Herein we report the mild synthesis of 15 phosphonocinnamic esters by means of a solvent-free mechanically activated Horner-Wadsworth-Emmons (HWE) olefination, in regular to excellent yields (13–99%), from tetraethyl methylenediphosphonate, an aromatic or aliphatic aldehyde and potassium tert-butoxide, using 5 min of mortar and pestle grinding. Potassium tert-butoxide acts as a base and liquid-assisting grinding agent. All isolated products were fully characterized as (E)-isomers through NMR spectroscopy. Furthermore, among the synthesized compounds diethyl (E)-2-(4-methoxyphenyl)vinylphosphonate 1 was discovered as an interesting cytotoxic agent inhibiting growth of two breast cancer cell lines (MDA-MB-453, IC50 = 79 µg/mL and MCF-7 IC50 = 64 µg/mL). To the best of our knowledge, this is the first report of mechanically activated HWE reaction for the synthesis of α, β-unsaturated phosphonates and the first time some of them have been assessed as cytotoxic agents on breast cancer cell lines. In conclusion, the fast and operationally simple synthesis of (E)-phosphonocinnamic esters afforded new promising cytotoxic agents in regular to excellent yields in very short reaction times.

Should I stay or should I go? migration intentions of teenagers with parents working abroad

ABSTRACT This paper investigates how having a parent working abroad affects subsequent intentions of teenagers to emigrate, using unique data for Poland. Results show that parental employment abroad is positively associated with children’s intentions to emigrate, more so for males than females. The findings highlight the intergenerational nature of migratory trends within families. This is particularly important for a country like Poland, which alongside other Central and Eastern European economies, has been experiencing significant population outflows for almost two decades and is gradually turning towards a foreign-born workforce.

The effect of apparent temperature on hospital admissions for cardiovascular diseases in rural areas of Pingliang, China.

INTRODUCTION AND OBJECTIVE There is a well-reported association between temperature and the relative risk (RR) of cardiovascular disease (CVD) in urban areas in China. However, insufficient research has been performed in rural areas. The aim of the study was to analyze the association between apparent temperature (AT) and the RR of CVD hospital admissions in rural areas of Pingliang, northwest China. MATERIAL AND METHODS Daily data and weather conditions were collected in Pingliang from 2014-2015. The median value of AT was selected to estimate the RR of CVD, and the distributed lag nonlinear model (DLNM) used to examine the relationship between AT and the RR of CVD admissions for up to 21 days. RESULTS The results showed a nonlinear relationship between AT and the RR of CVD admissions. Regarding the heat effect, there was a protective effect. Meanwhile, the cold effect on the RR of CVD admissions appeared at day 0 and persisted until day 21, resulting in a cumulative RR of 2.304 (95%CI: 1.809-2.936) compared with the median value of AT, and the maximum RR appeared at about -5 °. The cumulative RR values of CVD on men and adults were more sensitive than those on women and elders in the cold effect. CONCLUSIONS AT is associated with the hospitalization of CVD patients. Both gender and age factors were associated with the increase in RR of CVD admissions. More preventive measures should be taken to avoid this adverse effect.
Structural and chemical complexity of minerals: an update

Abstract The complexities of chemical composition and crystal structure are fundamental characteristics of minerals that have high relevance to the understanding of their stability, occurrence and evolution. This review summarises recent developments in the field of mineral complexity and outlines possible directions for its future elaboration. The database of structural and chemical complexity parameters of minerals is updated by H-correction of structures with unknown H positions and the inclusion of new data. The revised average complexity values (arithmetic means) for all minerals are 3.54(2) bits/atom and 345(10) bits/cell (based upon 4443 structure reports). The distributions of atomic information amounts, chemIG and strIG, versus the number of mineral species fit the normal modes, whereas the distributions of total complexities, chemIG,total and strIG,total, along with numbers of atoms per formula and per unit cell are log normal. The three most complex mineral species known today are ewingite, morrisonite and ilmajokite, all either discovered or structurally characterised within the last five years. The most important complexity-generating mechanisms in minerals are: (1) the presence of isolated large clusters; (2) the presence of large clusters linked together to form three-dimensional frameworks; (3) formation of complex three-dimensional modular frameworks; (4) formation of complex modular layers; (5) high hydration state in salts with complex heteropolyhedral units; and (6) formation of ordered superstructures of relatively simple structure types. The relations between symmetry and complexity are considered. The analysis of temporal dynamics of mineralogical discoveries since 1875 with the step of 25 years show the increasing chemical and structural complexities of human knowledge of the mineral kingdom in the history of mineralogy. In the Earth's history, both diversity and complexity of minerals experience dramatic increases associated with the formation of Earth's continental crust, initiation of plate tectonics and the Great Oxidation event.
