Abstract:

Abstract. The study examined the profiles of basic psychological needs satisfaction (BPNS) and frustration (BPNF) in a sample of older people living in French nursing homes. It is also addresses the relationships of these profiles with depressive symptoms and adaptation to nursing home. The residents ( N = 134) completed various French self-report questionnaires. Cluster analyses revealed five distinct profiles: (a) High BPNF ( n = 19); (b) Low BPN ( n = 36); (c) Moderate BPNS and low BPNF ( n = 23); (d) high BPNS and moderate BPNF ( n = 33); and (e) High BPNS ( n = 23). Practitioners and staff members should better respect residents’ needs if nursing homes are to become places to live rather than places only to receive care.

Abstract:

As a novel two-dimensional nanomaterial, black phosphorus nanosheets (BPNs) have good biocompatibility, biodegradability, and broadband saturable light absorption properties and, thus, have become a hot research topic in the biomedical field. However, BPNs suffer from poor stability caused by easy oxidative degradation and deactivation, and how to surface functionalize BPNs to improve their stability is a key issue to be solved. In this paper, we propose to realize the preparation of BPNs by the liquid-phase exfoliation method and study the surface functionalization modification of BPNs by silver ions (Ag+) and graphene oxide (GO). First, the preparation and characterization of BPNs were carried out by the liquid-phase exfoliation method to investigate the effect of process condition regulation on the planar size and thickness of BPNs, and the functionalization modification of BPNs by Ag+ and GO was carried out around the goal of enhancing the stability of BPNs. The experimental results showed that the stability of BPNs@Ag+ and BPNs@GO was significantly enhanced compared with that of unmodified BPNs. This study can be a reference for the future development of BP in the medical field.

Abstract:

Self-determination theory (Deci & Ryan, 2000) posits basic psychological need satisfaction (BPNS) as essential for optimal functioning and health. Grounded in this framework, the current study examined the role of BPNS in dancers’ cognitive appraisals and hormonal and emotional responses to performance stress. Dancers reported their degree of BPNS 1 month before a solo performance. Threat and challenge appraisals of the solo were recorded 2 hr before the performance. Salivary cortisol and anxiety were measured 15 min before, and 15, 30, 45, and 60 min postperformance. Higher BPNS was associated with lower cortisol responses and anxiety intensity. Challenge appraisals mediated the association between BPNS and cortisol. Threat appraisals mediated the BPNS–anxiety intensity relationship. These findings point to the potential importance of performers’ BPNS for optimal emotional and hormonal homeostasis in performance conditions.

Abstract:

Background Basic psychological need satisfaction (BPNS) is a significant factor in a person’s development, especially for adolescents, and the failure to satisfy these basic needs may contribute to individuals’ aggressive behavior. However, it is still unclear about the underlying mechanism by which BPNS is negatively associated with aggressive behavior. This study aimed to explore the relationship between BPNS and aggressive behavior in Chinese adolescents, with a focus on the mediating role of negative affect and its gender differences. Method A sample of 1,064 junior high school students from three schools in China were selected randomly for the cross-sectional survey. The revised Need Satisfaction Scale, the Positive and Negative Affect Schedule, and Youth’s Self-Report were used to measure BPNS, affect, and aggressive behavior. The proposed model was examined by the structural equation modeling test and multi-group comparison analysis. Results The results showed that BPNS was negatively linked with adolescents’ aggressive behavior, and this effect was mediated by negative affect. Moreover, multigroup analysis demonstrated that there existed a stronger negative association between BPNS and negative affect in female group. Also, the mediating effect of negative affect in the model was greater for girls. Conclusions Our findings highlighted the importance of BPNS in adolescents’ social behavior (i.e., aggressive behavior), and reveal disparate patterns in how BPNS affects aggressive behavior in girls as compared to boys.

Abstract:

Abstract The current study was conducted to examine the interactive effects of basic psychological needs satisfaction (BPNS), hedonic and eudaimonic motives on intrinsic regulation. To assess the causal relationship, two-wave time-lagged data collection was employed. A total of 159 youth athletes in Japan participated in online surveys twice (three-month time lag between two data points). The results indicated that the effect of BPNS on intrinsic regulation was moderated by hedonic and eudaimonic motives. Interestingly, BPNS negatively affected intrinsic regulation among youth athletes with low hedonic motives. This negative impact was further augmented when the level of eudaimonic motives was higher. Conversely, BPNS positively influenced intrinsic regulation among youth athletes with high hedonic motives. This positive impact of BPNS was more prominent when eudaimonic motives were lower. Overall, the findings suggest that when intrinsic regulation is the central concern, youth athletes should focus more on seeking enjoyment while putting self-development aside to maximize the positive impact of BPNS.

Abstract:

The aim of fitness technologies, a combination of wearables and associated applications, is to support users’ health and fitness regimes. The market for fitness technologies continues to increase, and the technologies themselves are quickly advancing. However, it is unclear how effective fitness technologies are in generating wellness outcomes, and there is concern regarding frequent discontinuance behaviors. Accordingly, we develop a model to explain how the perception that fitness technologies satisfy or frustrate users’ basic psychological needs (BPNs) in exercise mediates the relationships between the users’ goals for fitness technology use and psychological well-being and continuance. We find that users who start using fitness technologies for enjoyment, challenge, revitalization, affiliation, or to make positive improvements to their health or strength and endurance, are more likely to report that the fitness technologies are satisfying their BPNs, whereas users who start using them for stress management, social recognition, competition, or weight management are more likely to report BPNs frustration. Notably, users who start using fitness technologies for enjoyment and to make positive improvements to their health or strength and endurance are less likely to report BPNs frustration, and use driven by social recognition goals can decrease BPNs satisfaction. BPNs satisfaction is associated with both increased psychological well-being and continuance, whereas BPNs frustration is negatively associated with both. Fitness technologies must thus be perceived by users to satisfy their BPNs (i.e., autonomy, competence, and relatedness) in exercise to ensure positive outcomes from use.

Abstract:

This study aims to explore the importance of basic psychological needs satisfaction (BPNS) and mindfulness of university students in their career adaptability (CA), career self-efficacy (CSE), and future career choice (CC). The sample consisted of 1026 undergraduate students, of which 495 (48.2%) were female and 531 (51.8%) male, from three public universities in the Amhara Region, Ethiopia. The assessments, such as the Career Decision-Making Self-Efficacy Scale-Short Form, the Five Facet Mindfulness Questionnaire Short Form, the Career Adapt-Ability Short Form Five Scale, the Basic Psychological Needs Satisfaction Scale, and the Career Choice scale instruments were used. Findings from a parallel mediation model showed that both CA and CSE had a direct positive effect on the BPNS of university students. Additionally, this study found that both BPNS and mindfulness had a substantial and positive direct effect on the students’ CC. Importantly, we found that both CA and CSE significantly and indirectly predicted the future CC through BPNS and mindfulness. In addition, BPNS and mindfulness also partially mediate the relationship between CA, CSE, and the students’ future CC. Importantly, we found that mindfulness and BPNS fully and partially mediated the relationship between CA, CSE, and CC. These results support the notion that both psychological constructs (BPNS and mindfulness) play a crucial role in explaining the relationship between CA, CSE, and CC. By enhancing students’ BPNS and mindfulness, institutions can empower students to make informed decisions about their future career paths, ultimately nurturing their personal and professional growth.

Abstract:

The fulfilment of Basic Psychological Needs (BPNS)—autonomy, competence, and relatedness—has become a crucial factor influencing employee well-being and corporate performance across all sectors. This study examines the influence of Basic Psychological Needs (BPNS) on employee motivation and performance in insurance companies based on Self-Determination Theory (SDT). Despite substantial research on BPNs in sectors including education and healthcare, their influence on the insurance industry, especially in Malaysia, remains inadequately investigated. The findings indicate that meeting these needs can cultivate a supportive work environment, alleviate workplace difficulties, and enhance employee engagement and organizational efficiency. This research fills the literature gap by contextualizing the significance of BPNS concerning the performance of insurance agencies, highlighting the relationship between psychological well-being and firm performance. This study systematically reviews current studies to highlight the possibility of utilizing BPNS satisfaction to improve staff retention, satisfaction, and productivity, fostering insurance companies' competitive growth.

Abstract:

Based on the potential of digital media (DM) to increase students’ motivation in physical education (PE), this study investigated the effects of a theory-based tablet and smartphone intervention on students’ motivation in PE. A total of 309 students (8th and 9th grade) participated over five weeks. The intervention group (n = 161) carried out DM-supported PE lessons. Basic psychological need satisfaction (BPNS) and behavioral regulation were assessed. Results show no significant differences between groups on BPNS and behavioral regulation. However, BPNS moderated behavioral regulation regardless of the group. The non-significant results on BPNS and behavioral regulation show that the intervention did not lead to a significant improvement in motivation, which may be due to too little autonomy support, too little attractive content, and too little fun for the students. Future studies should investigate students’ preferences for DM in PE and use these findings to develop interventions to support BPNS in PE.

Abstract:

A importância do setor fitness na oferta de oportunidades para a promoção do exercício está alicerçada em profissionais qualificados, competentes e responsáveis pela dinâmica de prescrição e motivação do exercício. Com base na teoria da autodeterminação, este estudo examinou a interação entre as pressões percecionadas no trabalho e a motivação em profissionais de fitness. Os dados foram coletados de 366 profissionais do exercício (172 mulheres), usando um desenho transversal. Questionários avaliando a Perceção da Pressão de Trabalho (PJP) (organizacional; interno e clientes) e a Satisfação das Necessidades Psicológicas Básicas (BPNS) foram preenchidos online. A análise correlacional e de regressão foi usada para testar o modelo hipotético. Os resultados demonstram não haver associação entre qualificação profissional e níveis de pressão na BPNS. No entanto, é importante destacar que os níveis de pressão organizacionais estiveram negativamente associados à satisfação do total da BPNS (autonomia, competência e relacionamento positivo). Mais anos de experiência foram associados a menores valores de pressão e maior satisfação da competência. Em relação ao gênero, pressões e sua relação na BPNS, os homens apresentam uma maior satisfação das BPNS. As pressões organizacionais apresentam associações negativas com a satisfação das BPNS nos profissionais. Os resultados têm implicações teóricas e práticas: os líderes devem estar cientes do impacto negativo da pressão organizacional e a associação negativa com a satisfação das BPNS. O desenvolvimento de equipas com profissionais mais jovens e experientes, com reconhecimento e remuneração adequados, deve ser implementado como uma estratégia inclusiva, transmitindo segurança e confiança no futuro do setor fitness. Palavras-chave: motivação do instrutor de fitness; teoria da autodeterminação; pressões de trabalho; identidade profissional.

Abstract:

The harbour porpoise Phocoena phocoena is currently common in the Belgian part of the North Sea (BPNS), after decades of virtual absence. This article describes the results of aerial surveys to assess its distribution and density in Belgian waters, in concert with the first results of tests with passive acoustic monitoring devices (Porpoise Detectors - PoDs), and a basic analysis of strandings. The strandings data over four decades clearly demonstrate an increase of harbour porpoises in the BPNS, with only few stranded animals between 1970 and 1997 (0 to 6 per year), increasing numbers between 1998 and 2004 (8 to 40 per year), and even higher numbers between 2005 and 2009 (62 to 94 per year). The combined results of aerial surveys, strandings monitoring and tests with passive acoustic monitoring reveal a seasonal pattern, with harbour porpoises being abundant from February to April, and more scarce from May to January. Average densities in 2008 and 2009, as estimated by aerial monitoring covering most of the BPNS (with the exclusion of the nearshore 5 km strip), ranged from 0.05 animals per km², or in total less than 200 animals in an area equivalent to the BPNS in August 2009, to 1.01 animals per km², or in total almost 3,700 animals in an area equivalent to the BPNS during April 2008. In the first quarter of the year porpoises occur throughout the BPNS, including territorial waters (12 mile zone), whereas they are restricted to more offshore and northerly waters later in the year. Erratic invasions in the BPNS however blur general seasonal spatio-temporal patterns, which complicates our understanding of spatial distribution and migration.

Abstract:

Objectives: The self-determination theory (SDT) posits that basic psychological needs (BPNs) are indispensable and vital nutrients for well-being. The present research was done to apply SDT to understand students’ well-being, which proposes that the realization and fulfillment of BPNs and subjective vitality significantly influence the overall well-being of an individual. Therefore, the current study analyzed the mediational effect of subjective vitality in the BPN satisfaction and well-being relationship. Methods: This study included a sample of 219 (165 females and 54 males) university students with a mean age of 25 years. The basic psychological needs satisfaction and frustration scale (BPNSFS) was used to assess BPNs. Subjective vitality was assessed using a 6-item individual difference version subjective vitality scale by Ryan and Frederick, and well-being was evaluated by the WHO well-being index. Correlational and multiple regression analysis was done and mediational analysis was done using Hayes PROCESS macro. Results: The results indicated that fulfillment of BPNs (β=0.413, P<0.01) and subjective vitality (β=0.208, P<0.01) are significant predictors of students› well-being. Mediation analysis showed that subjective vitality completely mediated the relationship between BPN satisfaction and well-being. Furthermore, the measures of BPNS (t=2.242) and well-being (t=2.154) differed significantly, while no significant differences were found in subjective vitality (t=0.108) with respect to gender. Discussion: The findings of this study highlighted the role of BPN satisfaction and subjective vitality in the promotion of students’ well-being. Moreover, the present study highlighted the underlying mechanism, through which BPNs influences students’ well-being. This study contributes to the theoretical literature by emphasizing the vital role played by BPNs and subjective vitality in students’ well-being.

Abstract:

Abstract Past research reveals that basic psychological need satisfaction (BPNS) in relationship is an important contributor to relationship intimacy and individuals’ psychological well-being, but few studies explored the effects in grandparent-adult grandchildren relationship. The current study recruited 294 adult grandchild-closest grandparent dyads from mainland China. The grandchild and the grandparent completed a survey, respectively. We adopted Actor-Partner Interdependence Model to estimate both the actor and partner effects of BPNS on each partner’s relationship intimacy and psychological well-being while controlling relevant demographic variables. Results indicated that both grandparents’ and grandchildren’s BPNS in the relationship was related to their own higher relationship intimacy, bs =.20 and.27, ps &lt;.001, higher life satisfaction, bs =.32 and.17, ps &lt;.03, and fewer depressive symptoms, bs = -.17 and -.12, ps &lt;.001. Further, grandparents’ BPNS was also related to their grandchildren’s higher life satisfaction, b =.21, p =.01, and less depressive symptoms, b = -.07, p =.04, but adult grandchildren’s BPNS was not related to grandparents’ psychological well-being, ps &gt;.13. The findings indicate the significant role that BPNS plays in promoting relationship intimacy in the grandparent-adult grandchild relationship as well as in contributing to both partners’ psychological well-being. More importantly, the support from adult grandchildren to grandparents not only benefits the grandparent’s psychological well-being, but also the grandchild’s. The asymmetric effects suggest that the grandchildren may become the more influential support provider in their relationship with the grandparent when they have grown up.

Abstract:

Two-dimensional black phosphorus (BP) has emerged as a perspective material for various micro- and opto-electronic, energy, catalytic, and biomedical applications. Chemical functionalization of black phosphorus nanosheets (BPNS) is an important pathway for the preparation of materials with improved ambient stability and enhanced physical properties. Currently, the covalent functionalization of BPNS with highly reactive intermediates, such as carbon-free radicals or nitrenes, has been widely implemented to modify the material’s surface. However, it should be noted that this field requires more in-depth research and new developments. Herein, we report for the first time the covalent carbene functionalization of BPNS using dichlorocarbene as a functionalizing agent. The P–C bond formation in the obtained material (BP–CCl2) has been confirmed by Raman, solid-state 31P NMR, IR, and X-ray photoelectron spectroscopy methods. The BP–CCl2 nanosheets exhibit an enhanced electrocatalytic hydrogen evolution reaction (HER) performance with an overpotential of 442 mV at −1 mA cm−2 and a Tafel slope of 120 mV dec−1, outperforming the pristine BPNS.

We reported for the first time that cationic pillar[6]arene (cPA6) could tightly bind to peptide polymer (MW~20–50 kDa), an artificial substrate for tyrosine (Tyr) phosphorylation, and efficiently inhibit Tyr protein phosphorylation through host–guest recognition. We synthesized a nanocomposite of black phosphorus nanosheets loaded with cPA6 (BPNS@cPA6) to explore the effect of cPA6 on cells. BPNS@cPA6 was able to enter HepG2 cells, induced apoptosis, and inhibited cell proliferation by reducing the level of Tyr phosphorylation. Furthermore, BPNS@cPA6 showed a stronger ability of inhibiting cell proliferation in tumor cells than in normal cells. Our results revealed the supramolecular modulation of enzymatic Tyr phosphorylation by the host–guest recognition of cPA6.

Abstract:

Phrenic arterial blood flow has been shown to increase during bilateral phrenic nerve stimulation (BPNS). However, the role of unilateral phrenic nerve stimulation [left (LPNS) or right (RPNS)] on the blood flow and O2 consumption of the contralateral hemidiaphragm is not known and is explored here. In six anesthetized, mechanically hyperventilated dogs, left phrenic arterial blood flow (Qlpha) was measured (Doppler technique). Supramaximal (10 V, 30 Hz, 0.25-ms duration) LPNS, RPNS, and BPNS at a pacing frequency 15/min and duty cycle of 0.50 were delivered in separate runs. Left hemidiaphragmatic blood samples for gas analyses were obtained by left phrenic venous cannulation. During RPNS, Qlpha and left hemidiaphragmatic O2 consumption (VO2ldi) did not change significantly compared with control. During LPNS and BPNS, there was a significant increase in Qlpha and VO2ldi (P less than 0.01). There was no significant difference in Qlpha and VO2ldi between LPNS and BPNS (P greater than 0.05). We conclude 1) that there is a complete independence of left-right hemidiaphragmatic circulation both at rest and during diaphragm pacing and 2) that during unilateral stimulation transdiaphragmatic pressure is not related to diaphragmatic blood flow.

Abstract:

Previous research in this field has not examined the significance of each of the basic psychological needs (BPNs) on changes in the physical activity level, adherence to the Mediterranean diet (AMD), kinanthropometric and derived variables, and the physical fitness of adolescents. Therefore, the purpose of this study was (a) to examine the variances in physical activity, AMD, and kinanthropometric and derived variables, as well as fitness levels, among adolescents with varying degrees of satisfaction regarding each of the BPNs and (b) to assess the differences in the study variables among adolescents based on whether the BPNs are satisfied individually or jointly. The sample consisted of 791 adolescents (404 males and 387 females; average age: 14.39 ± 1.26 years old). The findings indicated that adolescents in the highest percentiles (75–100) of competence, autonomy, or relatedness showed higher scores in physical activity and AMD and better kinanthropometric and physical fitness variables than adolescents in the lowest percentiles (0–25). Adolescents who showed joint satisfaction of all BPNs showed the best results on all variables analyzed. In addition, it should be noted that competence played the most relevant role.

Abstract:

Background and objectivesBilateral electrical pudendal nerve stimulation (bPNS) reduces bladder hypersensitivity in rat models and anecdotally reduces pain in humans with pelvic pain of urologic origin. Concomitant opioids are known to alter responses to neuromodulation in some systems. So prior to the development of a clinical trial for purposes of regulatory approval, the preclinical interaction between opioids and stimulation effectiveness was examined.MethodsBladder hypersensitivity was produced by neonatal bladder inflammation in rat pups coupled with a second inflammatory insult as an adult. Morphine was administered acutely (1–4 mg/kg intraperitoneal) or chronically (5 mg/kg subcutaneously daily for 2 weeks prior to the terminal experiment). bPNS consisted of bilateral biphasic electrical stimulation of the mixed motor/sensory component of the pudendal nerves. Visceromotor responses (VMR; abdominal muscle contractile responses to urinary bladder distension (UBD)) were used as nociceptive endpoints.ResultsMorphine produced a dose-dependent inhibition of VMRs to UBD that was naloxone reversible. bPNS resulted in statistically significant inhibition of VMRs to UBD in hypersensitive rats that had received acute or chronic subcutaneous morphine injections.ConclusionsThis study suggests that inhibitory effects of bPNS can still be evoked in subjects who are receiving opioid therapy, thus giving guidance to potential clinical trials seeking regulatory approval for the treatment of chronic bladder pain.

Unfortunately, pseudostem is currently underutilised as a functional food ingredient due to its high-quality starch content. Therefore, this study aimed to determine the proximate compositions, physical attributes, and functional characteristics of starches produced from BP, in comparison with commercial starches, such as potato starch (PS) and corn starch (CS). Native starch from banana pseudostem (BPNS) was isolated. Then, resistant starch type III (RS3) was prepared from native starch (RS3BP) by an autoclaving process. The starches were subjected to physicochemical (i.e., proximate composition, water activity, bulk density, and colour), functional (i.e., amylose, amylopectin, water holding, and oil holding capacities), pasting (by using rapid visco analyser), and thermal properties determination (by using differential scanning calorimetry). The results showed that there were significant (p<0.05) increases in the amylose content of RS3BP after the autoclaving process. The water and oil holding capacities of BPNS did not change after autoclaving. The results of pasting and thermal properties indicated that BPNS contained a stronger starch granule and greater thermal stability than commercial starches (PS and CS). In addition, the autoclaving process decreased significantly (p<0.05) the content of moisture, crude protein, crude fat, and ash but increased significantly (p<0.05) the total carbohydrate and energy values in BPNS. The autoclaving process also resulted in a significant (p<0.05) darker and red-yellowish colour of RS3BP than other starches. In conclusion, the findings of this study demonstrated that the isolated BPNS has good starch granule stability and retains its functional properties after autoclaving during the production of RS3BP, even with an increased energy source. Therefore, BP can be considered a viable alternative raw material for producing native starch or resistant starch type III.

Abstract:

We examined the effects of hypoxia on exercise-induced diaphragmatic fatigue. Eleven subjects with a mean maximal O2 uptake of 52.4 +/- 0.7 ml.kg-1.min-1 completed one normoxic (arterial O2 saturation 96-94%) and one hypoxic (inspiratory O2 fraction = 0.15; arterial O2 saturation 83–77%) exercise test at 85% maximal O2 uptake to exhaustion on separate days. Supramaximal bilateral phrenic nerve stimulation (BPNS) was used to determine the pressure generation of the diaphragm pre- and postexercise at 1, 10, and 20 Hz. There was increased flow limitation during hypoxic vs. normoxic exercise. There was a decrease in hypoxic exercise time (normoxic 24.9 +/- 0.7 min vs. hypoxic 15.8 +/- 0.8 min; P < 0.05). After exercise the BPNS transdiaphragmatic pressure (Pdi) was significantly reduced at 1 and 10 Hz after both exercise tests. The BPNS Pdi was recovered to control values by 60 min postnormoxic exercise but was still reduced 90 min posthypoxic exercise. The mean percent fall in the stimulated BPNS Pdi was similar (normoxic -24.8 +/- 4.7%; hypoxic -18.8 +/- 3.0%) after both exercise conditions. Experiencing the same amount of diaphragm fatigue in a shorter time period in hypoxic exercise may have been due to 1) the increased expiratory flow limitation and diaphragmatic muscle work, 2) decreased O2 transport to the diaphragm, and/or 3) increased levels of circulating metabolites.

Abstract:

Based on the self-determination theory (SDT), this study used a mixed-methods (i.e., quantitative and qualitative approaches) design to explore the role of basic psychological need satisfaction (BPNS) played in sustained volunteering. Quantitative analysis of 803 college student volunteers revealed that competence and relatedness need satisfaction had significant associations with sustained volunteering, while autonomy need satisfaction did not. Furthermore, latent profile analyses identified five profiles of BPNS: low (Profile 1), relatively low (Profile 2), moderate (Profile 3), low autonomy-high competence and relatedness (Profile 4), and high (Profile 5). Volunteers in Profile 4 and Profile 5 reported higher sustained volunteering than those in other profiles. Subsequent qualitative synthesis of interview data from 33 college student volunteers found that competence need satisfaction (45.58%) was mentioned most frequently among the factors promoting sustained volunteering, then followed by relatedness (27.43%) and autonomy need satisfaction (11.06%). These findings highlight the important role of BPNS, especially competence and relatedness need satisfaction, in promoting college students’ long-term volunteering.

Abstract:

Ample evidence indicates that peer victimization is a crucial risk factor for adolescent internet gaming disorder (IGD); however, little is known about the mechanisms underlying this association. Based on the risk-buffering model and self-determination theory, this study tested whether parental knowledge moderated the relationship between peer victimization and adolescent IGD and whether this moderating effect was mediated by basic psychological needs satisfaction (BPNS). A sample of 3080 adolescents (Meanage = 14.51; SD = 1.97) anonymously responded to a set of questionnaires. The results revealed that the positive association between peer victimization and adolescent IGD was stronger among adolescents with parents who had low-level parental knowledge than for those with high-level parental knowledge. Moreover, this moderating effect was mediated by BPNS. These findings highlight that parental knowledge is an important protective factor against IGD for adolescents who experience peer victimization and BPNS is one mechanism that explains how this effect works.

Abstract:

Senior executives’ decisions can have a substantial impact on their own lives, their families, their organizations’ workers and employees, and society. This quantitative study (1) investigated the relationship between basic psychological need satisfaction (BPNS) at work and psychological well-being (PWB) in 142 senior executives as antecedent of their decision making and (2) compared the results to two other managerial level samples of 260 managers and 445 employees. The results have implications for theory and practice. Our findings contribute the new theoretical perspectives of differences in the relationship between BPNS at work and PWB by managerial level and senior executives’ gender (‘complementarity effect’). In turn, our research provides evidence for practical organizational applications such as the design and implementation of effective human resource development programs based on BPNS. Our findings further underscore the importance of senior executive psychology as a field of academic inquiry and provide directions for future research focused on further improving senior executives’ optimal functioning.

Full text

Abstract:

Due to its poor stability and rapid metabolism, the biological activity and absorption of epigallocatechin gallate (EGCG) is limited. In this work, EGCG-loaded bovine serum albumin (BSA)/pullulan (PUL) nanoparticles (BPENs) were successfully fabricated via self-assembly. This assembly was driven by hydrogen bonding, which provided the desired EGCG loading efficiency, high stability, and a strong antioxidant capacity. The encapsulation efficiency of the BPENs was above 99.0%. BPENs have high antioxidant activity in vitro, and, in this study, their antioxidant capacity increased with an increase in the EGCG concentration. The in vitro release assays showed that the BPENs were released continuously over 6 h. The Fourier transform infrared spectra (FTIR) analysis indicated the presence of hydrogen bonding, hydrophobic interactions, and electrostatic interactions, which were the driving forces for the formation of the EGCG carrier nanoparticles. Furthermore, the transmission electron microscope (TEM) images demonstrated that the BSA/PUL-based nanoparticles (BPNs) and BPENs both exhibited regular spherical particles. In conclusion, BPENs are good delivery carriers for enhancing the stability and antioxidant activity of EGCG.

Abstract:

The development of long-wavelength photoinduced copper-catalyzed azide–alkyne click (CuAAC) reaction routes is attractive for organic and polymer chemistry. In this study, we present a novel synthetic methodology for the photoinduced CuAAC reaction utilizing exfoliated two-dimensional (2D) few-layer black phosphorus nanosheets (BPNs) as photocatalysts under white LED and near-IR (NIR) light irradiation. Upon irradiation, BPNs generated excited electrons and holes on its conduction (CB) and valence band (VB), respectively. The excited electrons thus formed were then transferred to the CuII ions to produce active CuI catalysts. The ability of BPNs to initiate the CuAAC reaction was investigated by studying the reaction between various low molar mass alkyne and azide derivatives under both white LED and NIR light irradiation. Due to its deeper penetration of NIR light, the possibility of synthesizing different macromolecular structures such as functional polymers, cross-linked networks and block copolymer has also been demonstrated. The structural and molecular properties of the intermediates and final products were evaluated by spectral and chromatographic analyses.

Abstract:

Patulin (PAT), a type of mycotoxin existing in foodstuffs, is harmful to food safety and human health. Thus, it is necessary to develop sensitive, selective and reliable analytical methods for PAT detection. In this study, a sensitive aptasensor based on a dual-signaling strategy was fabricated, in which a methylene-blue-labeled aptamer and ferrocene monocarboxylic acid in the electrolyte acted as a dual signal, for monitoring PAT. To improve the sensitivity of the aptasensor, an in-plane gold nanoparticles–black phosphorus heterostructure (AuNPs-BPNS) was synthesized for signal amplification. Due to the combination of AuNPs-BPNS nanocomposites and the dual-signaling strategy, the proposed aptasensor has a good analytical performance for PAT detection with the broad linear range of 0.1 nM–100.0 μM and the low detection limit of 0.043 nM. Moreover, the aptasensor was successfully employed for real sample detection, such as apple, pear and tomato. It is expected that BPNS-based nanomaterials hold great promise for developing novel aptasensors and may provide a sensing platform for food safety monitoring.

Abstract:

This systematic review explores the integration of Universal Design for Learning (UDL) and Self-Determination Theory - Basic Psychological Needs Satisfaction (SDT-BPNS) in early childhood education. By analyzing 14 peer-reviewed articles from 2014 to 2024, this study identifies how UDL practices address relatedness, competence, and autonomy to enhance inclusive education. Findings reveal that collaborative learning environments and positive teacher-student relationships promote relatedness, especially when culturally adapted. Competence is enhanced through scaffolded learning, differentiated instruction, and teacher training programs, though limited resources and inadequate training remain challenges. Autonomy is supported by flexible, creative, and student-centered activities, but institutional constraints often limit its effectiveness. Integrating UDL with SDT-BPNS provides a comprehensive framework addressing both structural and psychological aspects of learning. This approach enhances motivation, engagement, and inclusivity by promoting emotional and cognitive well-being. However, cultural responsiveness, institutional support, and tailored training programs are essential for effective implementation. This review highlights the need for future research to explore long-term effects and develop culturally responsive UDL frameworks that incorporate SDT-BPNS principles.

Both groups exercised at 88–92% V˙o 2 maxfor about the same duration (15.2 ± 1.7 and 17.9 ± 2.6 min for high-fit and fit subjects, respectively, P > 0.05). The supramaximal BPNS test showed a significant reduction ( P< 0.01) in the BPNS transdiaphragmatic pressure (Pdi) immediately after exercise of −23.1 ± 3.1% for the high-fit group and −23.1 ± 3.8% ( P > 0.05) for the fit group. Recovery of the BPNS Pdi took 60 min in both groups. The high-fit group exercised at a higher absolute workload, which resulted in a higher CO2production (+26%), a greater ventilatory demand (+16%) throughout the exercise, and an increased diaphragm force output (+28%) over the initial 60% of the exercise period. Thereafter, diaphragm force output declined, despite a rising minute ventilation, and it was not different between most of the high-fit and fit subjects. In summary, the high-fit subjects showed diaphragm fatigue as a result of heavy endurance exercise but were also partially protected from excessive fatigue, despite high ventilatory requirements, because their hyperventilatory response to endurance exercise was reduced, their diaphragm was utilized less in providing the total ventilatory response, and possibly their diaphragm aerobic capacity was greater.

The input vectors of neural network comprise of spindle rotational speed, feed rates, vision flank wear, and cutting force signals. The output is the tool wear state which is either usable or failure. The detection of the abnormal states using BPNs achieves 97.5% reliability even when the spindle rotational speed and feed rate are changed.

(1) Background: Self-determination theory (SDT) claims that need supportive behavior is related to the satisfaction of the basic psychological needs: autonomy, relatedness and competence. The student–teacher relationship is of special interest to understand mechanisms of physical activity behavior change in physical education (PE). (2) Methods: In this cross-sectional study, 481 girls answered a German version of the Basic Psychological Need Satisfaction (BPNS) in PE Scale. Contrary to previous studies, the psychometric properties of this scale were examined by multilevel confirmatory factor analysis. (3) Results: A model with three latent factors on both levels showed acceptable fit and all items showed significant factor loadings. Although one item was excluded due to psychometric reasons, the scale showed good internal consistencies; α = 0.85 at the individual level and α = 0.84 at the class level. Subscales’ internal consistency at the individual levels was good, while at class level, the scores differed from poor to good. Small significant correlations of BPNS with moderate to vigorous physical activity support criterion validity. (4) Conclusion: The 11-item scale is a valid measurement tool to assess BPNS in PE and further application in the school setting would broaden the insights into the psychological impacts of SDT in PE.

Full text

Abstract:

Background: Spinal cord injury (SCI) is a devastating neurological condition with limited therapeutic options. Current clinical interventions predominantly rely on prolonged or high-dose pharmacological regimens, often causing systemic toxicity and adverse events. Although black phosphorus nanosheets (BPNSs) exhibit remarkable reactive oxygen species (ROS)-scavenging capacity to mitigate oxidative damage, their rapid degradation severely compromises their therapeutic efficacy. Methods: This study presents a thermosensitive hydrogel with rapid gelation properties by incorporating different proportions and concentrations of sodium alginate (SA) into a chitosan/β-glycerophosphate (CS/β-GP) hydrogel and loading it with BPNS for the treatment of SCI in rats. In vitro, the physical properties of the composite were characterized and the cytotoxicity and ROS scavenging abilities were assessed using PC12 cells; in vivo, behavioral tests, histopathological analysis, transcriptomics, immunohistochemistry, and Western blotting were performed to explore the therapeutic effects and mechanisms. Results: The results demonstrate that this hydrogel effectively slows BPNS degradation, exhibits a high ROS scavenging capacity, reduces lipid peroxidation, and thereby inhibits ferroptosis and apoptosis, offering neuroprotective effects and promoting motor function recovery. Conclusions: Our findings establish the CS/β-GP/SA-BPNS hydrogel as a multifunctional therapeutic platform for SCI, synergizing sustained drug release with ROS–ferroptosis–apoptosis axis modulation to achieve neuroprotection and functional restoration. This strategy provides a translatable paradigm for combining nanotechnology and biomaterial engineering in neural repair.

Abstract:

Herein, we report the neuroprotective and antioxidant activity of 1,1′-biphenyl nitrones (BPNs) 1–5 as α-phenyl-N-tert-butylnitrone analogues prepared from commercially available [1,1′-biphenyl]-4-carbaldehyde and [1,1′-biphenyl]-4,4′-dicarbaldehyde. The neuroprotection of BPNs1-5 has been measured against oligomycin A/rotenone and in an oxygen–glucose deprivation in vitro ischemia model in human neuroblastoma SH-SY5Y cells. Our results indicate that BPNs 1–5 have better neuroprotective and antioxidant properties than α-phenyl-N-tert-butylnitrone (PBN), and they are quite similar to N-acetyl-L-cysteine (NAC), which is a well-known antioxidant agent. Among the nitrones studied, homo-bis-nitrone BPHBN5, bearing two N-tert-Bu radicals at the nitrone motif, has the best neuroprotective capacity (EC50 = 13.16 ± 1.65 and 25.5 ± 3.93 μM, against the reduction in metabolic activity induced by respiratory chain blockers and oxygen–glucose deprivation in an in vitro ischemia model, respectively) as well as anti-necrotic, anti-apoptotic, and antioxidant activities (EC50 = 11.2 ± 3.94 μM), which were measured by its capacity to reduce superoxide production in human neuroblastoma SH-SY5Y cell cultures, followed by mononitrone BPMN3, with one N-Bn radical, and BPMN2, with only one N-tert-Bu substituent. The antioxidant activity of BPNs1-5 has also been analyzed for their capacity to scavenge hydroxyl free radicals (82% at 100 μM), lipoxygenase inhibition, and the inhibition of lipid peroxidation (68% at 100 μM). Results showed that although the number of nitrone groups improves the neuroprotection profile of these BPNs, the final effect is also dependent on the substitutent that is being incorporated. Thus, BPNs bearing N-tert-Bu and N-Bn groups show better neuroprotective and antioxidant properties than those substituted with Me. All these results led us to propose homo-bis-nitrone BPHBN5 as the most balanced and interesting nitrone based on its neuroprotective capacity in different neuronal models of oxidative stress and in vitro ischemia as well as its antioxidant activity.

This paper aims to shed light on a sample of 681 members of sports teams belonging to different Spanish clubs (391 boys and 290 girls), with a mean age of 16.2 years, and a high sports dedication (75.5% > 5 years of experience; 96.3% > two training sessions/week; 90.3% > 3 hours of training/week). The collected data used self-reports based on the tenets of achievement motivation, Self-Determination Theory, and fear of failure. Those aspects linked to task involvement were positively close to Basic Psychological Needs (BPNs), while those related to ego involvement moved away from task involvement and BPNs. Fear was associated positively and significantly only with ego, and negatively with the rest of the constructs. In the standardized direct effect, positive and significant associations were observed among all constructs except between an ego-involving climate and basic psychological needs satisfaction. The association between a task-involving climate and BPNs was significant in fostering relationships among group members, as well as in improving interpersonal cohesion, empathic understanding processes, and reducing fear of failure in youth athletes.

Abstract:

Considerable evidence has shown that social class has a positive relationship with well-being. However, little research has examined this connection in detail, particularly as it relates to the context of adolescence. The present study builds on the framework of Self-Determination Theory, to delineate the psychological mechanism underlying this relationship in adolescents. Study 1 explored the correlation between objective social class and hedonic well-being with national adolescent data ( n = 944) from the China Family Panel Studies. The results showed that objective social class was positively correlated with hedonic well-being. Study 2 more fully examined the correlation and potential mechanism of the relationship between social class and hedonic/eudaimonic well-being among 625 adolescents. The results confirmed that social class is correlated with hedonic/eudaimonic well-being and that basic psychological needs satisfaction (BPNS) fully mediates the relationships between them. These findings emphasize the role of BPNS in this relationship among adolescents.

Abstract:

Black phosphorus nanoribbons (BPNs) might offer alternatives to narrow-gap compound semiconductors for tunable optoelectronics in infrared region. In this work we present a quantum perturbation theory on two-photon absorption (TPA) in monolayer armchair-edged black phosphorus nanoribbons (acBPNs) employing the reduced two-band model within the long-wavelength BP Hamiltonian. The matrix elements for one-photon transition have been derived and the TPA spectrum associate with intra conduction band transition and inter band transition have been drawn. The calculations predict that the TPA coefficient in acBPNs is in the magnitude of 10−6 m/W in visible region, which is 4 orders higher than the conventional semiconductor quantum dots. And in infrared region, there is a giant TPA coefficient, which is mainly contributed from intra band transitions and can reach up to10−1 m/W. The TPA peaks can be tuned both by the width of BPNs and the electron relaxation energy.

Abstract:

With the continuous progress of modern science and technology and the increasing requirements for marine transport in various fields, the intelligence and automation of ships has become a general trend. Autonomous unmanned surface vessel (UASV) control generally includes UASV trajectory planning, path tracking control, and autonomous collision avoidance control. Due to their low cost, small size, fast action, reconnaissance capabilities and other advantages, BPNS play a very important role in everyday life, emergency response and scientific research. UASV, as a rule, consist of a platform and a payload system. But in the whole process of UASV navigation, autonomous mooring is also an important part. And there are fewer studies on the automatic mooring algorithm of UASV. The advanced technology of autonomous mooring of BPNS can effectively reduce the cost of human, material and financial resources, while reducing the accident rate in a reasonable and safe manner. Therefore, it is very important to comprehensively promote the development of autonomous navigation and mooring technology of UASV. Keywords: Autonomous unmanned surface vessel (UASV), autonomous mooring.

Abstract:

AbstractBenzocyclobutene‐functionalized polysiloxane microspheres with high sphericity and narrow size distribution on the nanometer (BPNS) and micrometer (BPMS) scale were prepared by the hydrolysis‐condensation reaction of benzocyclobutene vinyl trimethoxysiloxane (BCBVST) in the absence of surfactants, respectively. In this paper, we systematically investigate the relationship between hydrolysis conditions and BPNS/BPMS size. The results show that the method developed in this paper is characterized by simple manipulation, controllable microsphere size, and high repeatability. A possible mechanism for the formation of BPMS has been proposed.

Abstract:

Abstract Photocatalytic CO2 reaction is considered to be an effective way to reduce greenhouse gas emission. Herein, a novel and efficient 2D/2D black phosphorus nanosheets (BPNS)-Bi2MoO6 photocatalyst was synthesized and used for photocatalytic CO2 reduction. Compared with Bi2MoO6, the photocatalytic activity of BPNS-Bi2MoO6 composite photocatalyst was significantly improved. When the mass ratio of BPNS to Bi2MoO6 was 1:100, the BPNS-Bi2MoO6 photocatalyst exhibited the optimal activity for photocatalytic CO2 reduction, and the production of CO reached 72.8 μmol·g-1 after reaction for 4 h, which was 1.5 times than that of Bi2MoO6. Moreover, the BPNS-Bi2MoO6 showed high stability for photocatalytic CO2 reduction reaction, after reaction for four cycle experiments, the production of CO only reduced by 10%. The enhanced light absortion, enhanced separation of electrons and holes, and the tight 2D/2D heterojunction formed between BPNS and Bi2MoO6 account for the high photocatalytic performance of BPNS/Bi2MoO6.

Abstract:

IntroductionBasic psychological needs satisfaction (BPNS) and Emotional intelligence (EI) have been underscored as helpful psychological constructs in explaining academic engagement. However, the joint interaction of BPNS with EI abilities to explain academic engagement has not been tested. Therefore, the present study aimed to investigate the interactive role of BPNS with EI abilities in the prediction of academic engagement in a sample of Chinese university students.MethodsA questionnaire survey was administered to a sample of 466 university students. The data were analyzed using the SPSS (version 21.0) software. The first analysis consisted of descriptive statistics (including mean and standard deviation) and Pearson’s correlations among BPNS, EI, and academic engagement. Through structural equation modeling (SEM), direct and indirect effects were calculated.ResultsThe results showed that BPNS was positively associated with academic engagement and that only the Use of emotion dimension of EI mediated these associations.DiscussionThese results suggest that important interventions incorporated with BPNS and EI abilities, especially the use of emotion ability, may be performed to promote university students’ academic engagement.

Abstract:

Background: The development of mobile Internet technology has brought great changes and convenience in our daily life. However, it has also arisen a series of mental health problems, especially problematic mobile phone use (PMPU). Objective: This study aimed to explore the relationship between social exclusion and PMPU among Chinese college students, as well as the mediating role of basic psychological needs satisfaction (BPNS). Method: We recruited a total of 340 participants (mean age 19.71, 44.7% males) from a university in China by convenience sampling. All of them completed the self-report tests of the Social Exclusion Scale, BPNS Scale and Mobile Phone Addiction Index Scale. Data analysis was performed in SPSS 23.0, using the PROCESS macro to examine the mediating effect. Results: Social exclusion was significantly positively correlated with PMPU (r = 0.22, p < 0.001), and significantly negatively correlated with BPNS (r = –0.66, p < 0.001), and BPNS was significantly negatively correlated with PMPU (r = –0.24, p < 0.001). BPNS played a mediating role in the relationship between social exclusion and PMPU. In addition, autonomy needs and competence needs mediated the link of such a relationship, whereas the mediating role of relatedness needs was not significant. Conclusions: Results showed that social exclusion was closely related to PMPU, and social exclusion affected PMPU through BPNS. These findings underline the important role of social relationship and BPNS on adolescents’ PMPU.
