Acculturation, perceived discrimination, academic identity, gender and Chinese language learning among Ethnic Minority Adolescents: a structural equation modeling analysis

ABSTRACT Parents, teachers and policy makers are concerned about how immigrant students acquire the mainstream language and achieve academic success. Therefore, researchers face an urgent need to examine the broader ecological factors that influence immigrant students’ academic identity construction and mainstream language learning. This study investigates the nexus of acculturation, gender, identity and Chinese language learning among 881 South Asian immigrant adolescents in Hong Kong. The results indicate that students with stronger academic identity report superior Chinese reading and writing, and the results show that among ethnic minorities, girls reported higher level of Chinese reading and writing than boys. Paradoxically perhaps, students who perceived greater discrimination didn’t show significantly different academic identity from other students and reported higher proficiency in reading and writing Chinese. This implies the necessity of providing more school and social support to these students. The study also shows that students with greater assimilation have weaker academic identity and hence report poorer Chinese reading and writing. The negative link between assimilation and mainstream language learning suggests the importance of maintaining the heritage identity and sense of belonging to heritage culture for enhancing the ethnic minority students’ mainstream language learning. This result informs policy makers developing suitable immigration policy.
3D-Printed Quasi-Absolute Electromagnetic Encoders for Chipless-RFID and Motion Control Applications

This paper presents electromagnetic encoders useful for chipless-RFID and motion control applications. The encoders consist in a pair of linear chains of rectangular apertures implemented by means of 3D printing. One of these chains is periodic and acts as a clock, whereas the other chain contains an identification (ID) code. With these two aperture chains, the ID code can be synchronously read, so that the relative velocity between the tag and the reader is irrelevant. Additionally, it is shown in the paper that by properly designing the reader, it is possible to determine the motion direction. The sensitive part of the reader is a microstrip line loaded with three complementary split ring resonators (CSRRs) etched in the ground plane and fed by three harmonic signals. By encoder motion, the characteristics of the local medium surrounding the CSRRs are modified, and the harmonic signals are amplitude modulated (AM) at the output port of the line, thereby providing the clock signal (which gives the encoder velocity), the ID code (providing also the quasi-absolute position) and the direction of motion. A fabricated prototype encoder is characterized by reading it with a dedicated reader.
Oligocene–Miocene Dinoflagellate Cysts from the San Gregorio Formation, La Purísima Area, Baja California Sur, Mexico

ABSTRACT Dinoflagellate cysts from the LB-5 core in the San Gregorio Formation (SGF) from the La Purísima area, Baja California Sur, Mexico, limit the age of the studied succession to Oligocene–Miocene (28–20Ma). Our results allow correlation of this core with the type locality and another well-dated sections of the SGF in the region, namely the nearby La Purísima section, with an unequivocal Oligocene–Miocene boundary (O/M – 23Ma). Lithology and dinoflagellate cyst data indicate mainly marine sedimentary environments, with a transgression from continental at the base to upper bathyal (200–500 m) in the O/M level (∼243 m), and a regression towards the top of the unit. Dinoflagellate cysts are virtually absent in some intervals, probably due to oxidation during diagenesis. The abundance of heterotrophic taxa during intervals with high cyst concentrations indicates that palynological preservation was adequate for quantitative analyses in the rest of the samples. Samples with dinoflagellate cyst concentrations >2000 cysts/gram of sediment (c/g sed), the abundance of heterotrophic taxa, and the presence of phosphoritic layers and diatomites indicate high biogenic productivity during the deposition of the SGF. Intense upwelling conditions in the area are probably associated with the cold events Mi-1 (∼23Ma) near the O/M and Mi-1a (∼21.7Ma) at ca. 170 m depth. Quantitative dinoflagellate cyst data in the LB-5 core suggest lower productivity (mean = 203 c/g sed) in the Oligocene than during the Miocene (mean = 848 c/g sed) interval. The absolute abundances of the Miocene intervals indicate similar dinoflagellate cyst concentrations in the LB-5 core and modern samples from the Pescadero Basin in the southern Gulf of California.
The numerical reconcilability of Bayesian measure and p-value in interval hypotheses is not possible in general

Abstract The interval null hypothesis is considered against the two-sided hypothesis. It was shown that p-value in interval null hypothesis can be numerically approximated by p-value of point null when interval converges to a single point of hypothesis. However, it is not true for Bayes factor or posterior probability. When the null hypothesis is substituted to interval one, p-value may be in the range of the posterior probability. In this case, there are a substantial differences between null point and interval null hypothesis in Bayesian measures. The results are shown in more detail in exponential distribution. But can be generalized to gamma distribution.
Self-distancing and narrative wisdom in older adults’ autobiographical reflection

Abstract The aim of the study was to explore the relationship between the ability of older adults to distance themselves from their life stories and the intensity of their narrative wisdom. In the study, we followed a narrative-constructivist approach while using mixed research strategies, including our working concept of narrative wisdom. We used our original coding system to analyze the transcripts of life stories obtained from 259 Polish older adults (aged 60 to 97). The coding outcomes were subsequently compared with the self-distancing questionnaire results. Our findings suggest that self-distancing is a differentiating factor for the strategies used by older adults in their autobiographical reflection: in its structure-, content-, and process-related qualities. When based on self-distancing strategies, narrative autobiographical reflection correlates with a higher sense of purpose and a higher level of agency. This interplay facilitates older adults in their author-like, flexible, and open attitudes toward their life stories; it can also be applied in counseling and older adults’ therapy.
Emplacing linked lives: A qualitative approach to understanding the co‐evolution of residential mobility and place attachment formation over time

Despite growing interest in issues of residential mobility and place attachment in a globalised world, research within Environmental and Community psychology has tended to overlook the ways that interpersonal relations, and wider socio‐political and economic structural factors inform place attachment formation amongst residentially mobile individuals We address this gap drawing on the Human Geography concept of ‘Linked Lives’ (Coulter et al , Progress in Human Geography, 2016, 40(3), 352–374), to conceive the relocation decisions of residentially mobile individuals, and their place (non)attachment to the current residence place, as deeply intertwined with formative place experiences, interpersonal relations, and the structural contexts within which people live (Coulter et al , Progress in Human Geography, 2016, 40(3), 352–374) With the aim of deepening understanding of the co‐evolution of residential mobility and place attachment, this paper presents narrative case studies of residents living in a town in Southwest England, with each resident indicating a different variety of people–place relations to their current residence place Findings indicate that moving intentions and consequent residential place attachment result from complex interactions over time between (a) formative place experiences and settlement identities, leading to preferred types of residence place;(b) interpersonal relations with significant others including family and community members that vary according to life stage events;and (c) structural forces, comprising cultural, economic, and political factors shaping people's lives Future research could examine how structural changes arising from the COVID‐19 pandemic are influencing residential mobilities and attachments to place [ABSTRACT FROM AUTHOR] Copyright of Journal of Community & Applied Social Psychology is the property of John Wiley & Sons, Inc and its content may not be copied or emailed to multiple sites or posted to a listserv without the copyright holder's express written permission However, users may print, download, or email articles for individual use This abstract may be abridged No warranty is given about the accuracy of the copy Users should refer to the original published version of the material for the full abstract (Copyright applies to all Abstracts )
Conformational variability in proteins bound to single‐stranded DNA: A new benchmark for new docking perspectives

We explored the Protein Data Bank (PDB) to collect protein–ssDNA structures and create a multi‐conformational docking benchmark including both bound and unbound protein structures. Due to ssDNA high flexibility when not bound, no ssDNA unbound structure is included in the benchmark. For the 91 sequence‐identity groups identified as bound–unbound structures of the same protein, we studied the conformational changes in the protein induced by the ssDNA binding. Moreover, based on several bound or unbound protein structures in some groups, we also assessed the intrinsic conformational variability in either bound or unbound conditions and compared it to the supposedly binding‐induced modifications. To illustrate a use case of this benchmark, we performed docking experiments using ATTRACT docking software. This benchmark is, to our knowledge, the first one made to peruse available structures of ssDNA–protein interactions to such an extent, aiming to improve computational docking tools dedicated to this kind of molecular interactions.
Stream Temperature and Environment Relationships in a Semiarid Riparian Corridor

This study examined the relationship between stream temperature and environmental variables in a semiarid riparian corridor in northcentral Oregon, USA. The relationships between riparian vegetation cover, subsurface flow temperature, and stream temperature were characterized along an 800 m reach. Multiple stream temperature sensors were located along the reach, in open and closed canopy areas, with riparian vegetation cover ranging from 4% to 95%. A support vector regression (SVR) model was developed to assess the relationship between environmental characteristics and stream temperature at the larger valley scale. At the reach scale, results show that air temperature was highly correlated with stream temperature (Pearson’s r = 0.97), and no significant (p < 0.05) differences in stream temperature levels were found among sensor locations, irrespective of percent vegetation cover. Channel subsurface temperature levels from an intermittent flow tributary were generally cooler than those in the perennial stream in the summer and warmer during winter months, indicating that the tributary may have a localized moderating effect on stream temperature. At the valley scale, results from the SVR model showed that air temperature, followed by streamflow, was the strongest variable influencing stream temperature. Also, riparian area land cover showed little effect on stream temperature along the entire riparian corridor. This research indicates that air temperature, subsurface flow, and streamflow are important variables affecting the stream temperature variability observed in the study area.
Child-rearing experiences of mothers with early adolescents in Korean multicultural families

Purpose This study was conducted to explore the child-rearing experiences of mothers with early adolescents in Korean multicultural families. Methods The participants were six mothers with early adolescents in Korean multicultural families. Data were collected through in-depth interviews. The main question was, "Could you tell me about your child-rearing experiences with your adolescent child? " The data were analyzed using qualitative content analysis. Results Four categories resulted from the analysis of child-rearing experiences of mothers with early adolescents in Korean multicultural families, as follows: "separation between myself and others", "distance between myself and my adolescent child", "making efforts to bridge the gap between myself and others", and "trying to connect with my adolescent child closely". Conclusion These findings indicate that mothers in Korean multicultural families made many efforts to bridge the gap between themselves and other people, and tried to connect with their children closely. The findings of this study emphasize specific aspects of how mothers with early adolescents experienced child-rearing in Korean multicultural families.
A Model of Anchoring and Adjustment for Decision-Making under Risk

We introduce a general model of anchoring and adjustment for decision-making under risk. To evaluate a lottery, agents first anchor on the simple mean of the lottery's outcomes, ignoring the outcomes' probabilities. Then, they adjust the anchor (insufficiently) in the direction of the lottery's expected utility. The resulting model implies behavior which is observationally similar to established prospect theory models. However, it is not rank-dependent and naturally applies to lotteries with any given number of outcomes, including continuous lotteries. We consider a number of applications to demonstrate the model's range. For the discrete case, we show how the model can explain four commonly-observed choice anomalies - both Allais paradoxes, the St. Petersburg paradox, event-splitting effects, and the effect of probability in the fourfold pattern of risk attitudes. For the continuous case, we show how the anchoring model can be applied to the equity premium puzzle. We also use historical data on asset returns to show that equity premiums can be explained by reasonable combinations of preference parameters. The anchoring model is an attractive and flexible tool that assumes people want to simplify complex decision processes.
Role of Lung Ultrasound in the Management of Patients with Suspected SARS-CoV-2 Infection in the Emergency Department

Background: The lung ultrasound (LUS) score has been proposed as an optimal scheme for the ultrasound study of patients with suspected/confirmed COVID-19 pneumonia. The aims of our study were to evaluate the use of lung ultrasound as a diagnostic tool for diagnosing SARS-CoV-2 pneumonia, to examine the validity of the LUS score for the diagnosis of COVID-19 pneumonia, and to correlate this score with hospitalization rate and 30-day mortality. Materials and Methods: A retrospective analysis was performed on 1460 patients who were referred to the General Emergency Department of the S. Orsola-Malpighi Hospital from April 2020 to May 2020 for symptoms suspected to indicate SARS-CoV-2 infection. The ultrasound examination was based on a common execution scheme called the LUS score, as previously described. Results and Conclusions: The LUS score was found to correlate with the degree of clinical severity and respiratory failure (paO2/FiO2 ratio and the alveolar–arterial gradient increase than expected for age). It was shown that COVID-19 patients with an LUS score of >7 require the use of oxygen support, and a value of >10 is associated with an increased risk of oro-tracheal intubation. The LUS score was found to present higher values in hospitalized patients, increasing according to the degree of care intensity. Patients who died from COVID-19 were characterized by a mean LUS score of 11 at presentation to the emergency department. An LUS score of >7.5 was found to indicate a sensitivity of 83% and a specificity of 89% for 30-day mortality in COVID-19 patients. The use of LUS seems to be an optimal first level method for pneumonia detection and risk stratification in patients with suspected SARS-CoV-2 infection.
Knowledge, Attitudes, and Practices (KAP) Regarding Physical Activity among Healthcare Professionals (HCPs) in Suva, Fiji

BACKGROUND: More than 60% of the world’s population is not physically active. Physical inactivity affects all sectors of the population including among healthcare professionals (HCPs). The objective of this study was to determine the level of knowledge, attitudes and practices (KAP) regarding the concept, benefits and health consequences of physical activity (PA) among HCPs in Suva, Fiji. METHODS: This quantitative, cross-sectional study was conducted among HCPs in Suva, Fiji between 1 July 2017 and 22 September 2017. All available HCPs including doctors, nurses and paramedics who were willing to take part in the study were included. A validated self-administered questionnaire was used to assess the level of KAP regarding PA. Data was analysed with Statistical Package for the Social Sciences (SPSS) 25. RESULTS: 126 HCPs participated in this study with the majority being female (73.8%), in the age range of 33 – 42 years (47.6%), married (81.7%), from the nursing profession (54.0%) and within 0-5 years of experience (27.0%). The results showed that most of the participants (96.8%) had a high level of knowledge, positive attitudes (100%) and good practice (95%) regarding PA. CONCLUSION: Although the study participants had high levels of knowledge and positive attitudes towards PA, it is important to promote their practice. Using tailored behavioural change theories that focus on perceived benefits and barriers of PA may help decision-makers to promote PA in the workplace and among HCPs in Fiji.
Preliminary investigations on effects of polycyclic aromatic hydrocarbons on embryos of widow tetra, Gymnocorymbus ternetzi Boulenger

Polycyclic aromatic hydrocarbons (PAHs) present in crude oil effluents, when released into aquatic ecosystem pose a major threat to fishes and humans. We investigated the harmful effects of PAHs on early embryonic and larval development of Gymnocorymbus ternetzi. Embryos when exposed to samples containing Dibenzothiophene (3 rings), Phenanthrenes (3 rings) and Pyrenes (4 rings) at varying concentrations (15–90 μg/L) exhibited defective embryonic and larval development. As PAHs targets aryl hydrocarbon receptor (AhR) pathway, cardiac deformities were persistent in embryos exposed to PAHs for >48 hrs; concentration specific defects included arrested embryonic development (36 ± 2.6%), cytoplasmic blubbing (24%), pericardial edema and cardiac looping (43 ± 4.2%) and tail bents and body curvature (19%). However, embryonic defects were reversible (>47%) when transferred to clean water immediately after <24hrs of exposure. Suitability of tetras for eco-toxicology studies to investigate effects of aquatic pollutants on embryonic development, advantages and disadvantages are discussed.
Growth curves of different free-range chicken lineages by the Gompertz model

The knowledge of the dynamics of animal growth over time can be done through non-linear equations. Thus, the objective was to describe and compare the growth of three free-range chicken lineages based on the Gompertz equation. 180 unsexed chickens assigned to three treatments (Pesadao Vermelho, Pescoco Pelado and Carijo Pesado lineages) in a randomized design with six replicates, with 10 birds per experimental unit. Broilers were weighed weekly (until 77 days of age), these data were used to estimate the growth curve and determine the equation parameters (A, B and C) of model used. The comparison tests between the model parameters for each lineage, demonstrated that it is necessary an equation with different A, B and C parameters for each lineages, the lack-of-fit test was not significant (p>0.05), therefore, the equations of the model are suitable to describe the growth of the lineages. The Pesadao Vermelho lineages is heaviest at inflection point and earlier (BWe =1,528 g at 39 days of age), compared to the Pescoco Pelado (BWe=1,185 g at 38 days of age) and the Carijo Pesado (BWe=1,183 g at 51 days of age) lineage. The adjusted Gompertz curves accurately estimated growth curves of the evaluated line-ages. An equation with different A, B and C parameters is required for each lineage. The Pesadao Vermelho lineage is heaviest at maturity. The Carijo Pesado lineage has a slow growth, with low weight at maturity and the oldest age at maturity.
The transformative leadership compass: six competencies for digital transformation entrepreneurship

PurposeIn the digital age, companies require leaders to foster digital transformation entrepreneurship, i.e. the organisational attitude and orientation of the creation of a new business or the development of an existing business by having at the core or embracing digital transformation as the continuous development and application of digital knowledge for companies' value creation. This paper identifies six critical competencies distinguishing the transformative leadership profile supporting enterprises' digital transformation development.Design/methodology/approachThe paper, through a critical literature review focussing on three research streams, i.e. wise, transformative and digital leadership, addresses the following research question: What competencies characterise a digital transformative leader promoting and encouraging digital transformation entrepreneurship? Methodologically, first, explorative analysis of the literature has been carried out exploring the role and relevance of leadership in driving companies' digital transformation. Second, focussing on the three leadership perspectives, wise, transformative and digital, the critical features distinguishing each view have been identified. A set of hypotheses has been formulated to develop a framework to profile a digital transformative leader. In the third stage, the framework of the digital transformative leadership compass has been developed.FindingsThe paper profiles the digital transformative leader, a critical figure in companies competing in the digital age to nurture digital transformation entrepreneurship. Six specific competencies are synthesised and proposed throughout the transformative leadership compass. It is presented as an interpretative framework helpful to understand what affects the organisational culture and behaviours driving digital transformation. The proposed model defines theoretical foundations to operationalise an assessment framework and developing empirical research about leadership characteristics hampering and enabling successful companies' digital transformation.Originality/valueThe study proposes a novel framework based upon a critical analysis of the leadership literature. Combining insights gathered from the literature review on transformative, wise and digital leadership, the need for nurturing a transformative digital leadership allowing enterprises to stay competitive and able to change and adapt to the scenario's evolution emerged. Accordingly, the paper defines the digital transformative leader as a leadership profile sustaining organisational and digital transformation. The transformative leadership compass is proposed as a model to outline the critical competencies distinguishing a digital transformative leader capable of driving continuous company innovation and specifically digital transformation entrepreneurship.
