Authors: Tantirattanakulchai Pankaew , Hounnaklang Nuchanad 
Published: April 2021

PurposeThe purpose of this paper is to evaluate the prevalence of depression and to determine the association between social support and depression among transgender women in Bangkok, Thailand.Design/methodology/approachA cross-sectional study was conducted among 280 transgender women in Bangkok, Thailand between March 2019 and May 2019 using the snowball sampling method. Data were collected through a self-administered questionnaire. The questionnaire included demographic questions and measures of social support (MSPSS) and depression (CES-D). Multivariable logistic regression analysis was employed to explore the association between social support and depression.FindingsThe prevalence of depression among transgender women was 58.2%. Multivariable logistic regression analysis indicated that depression was significantly associated with perceived low social support (OR: 9.55, 95%CI: 2.10–43.39) and moderate social support (OR: 2.03, 95%CI: 1.19–3.46) after being adjusted for religion, sufficient income and alcohol drinking.Originality/valueTransgender women were prone to experience a higher prevalence of depression than the general population. Social support would reduce the risk of depression among transgender women. Therefore, social support service systems for transgender women should be embedded into organizations concerned.
The impact of gender on the evaluation of vertical line extensions of luxury brands: a cross-national study
Authors: Boisvert Jean , Ashill Nicholas Jeremy 
Published: April 2021

Purpose
The purpose of this study is to assess the extent to which gender impacts the evaluation of vertical line extensions of luxury brands in a cross-national context. The topic of brand/line extensions has been investigated in the mainstream branding literature. On the other hand, the topic has received less attention in the luxury literature. At the same time, while research has examined brand/line extensions from an international perspective, the impact of gender on consumer purchase intentions of luxury downward line extensions in different countries has remained unexplored.

Design/methodology/approach
Based on an ANOVA design (2 extension types × 2 genders × 2 countries). The independent variables were ordered as follows: gender (male/female), vertical line extensions (upscale/downward) and country of living (France/USA). The purchase intention of the extension was chosen as the dependent variable.

Findings
The study results show that key differences exist between men and women regarding vertical luxury line extensions. For instance, women in both countries rate a new downward line extension of a luxury brand more positively than men. In contrast, although women evaluate a new upscale line extension of a luxury brand similarly to men in France, women are more positive than men in the USA. Also, US men rate an upscale extension less positively than their French counterparts. Finally, women in both countries rate luxury downward extensions more positively than men.

Originality/value
This study contributes to the literature of luxury brand management by examining how gender types process and respond to upscale and downward luxury line extensions versus purchase intentions in two different countries. This paper is unique as gender types are not often compared in previous research while fundamental distinctions exist, leading to significant differences. Practically, this study also provides key insights for marketing strategy development and adjustment for luxury manufacturers in terms of their target market, more specifically men versus women.

Authors: Aren Selim , Hamamci Hatice Nayman , Özcan Safvan 
Published: April 2021

Purpose
The aim of this study, the moderating effect of pleasure-seeking and loss aversion, was investigated in relation to the big five personality traits with regard to risky investment intentions.

Design/methodology/approach
In the study, the data was obtained between January and November 2019 via an online survey with convenience sampling. The total number of subjects is 886. The authors used IBM SPSS Statistics for analysis. Exploratory factor analysis, correlation analysis, regression analysis and discriminant analysis were performed.

Findings
Significant relationships were found between five personality traits and risky investment intentions. In these relationships, the moderator effect of pleasure-seeking for extraversion, conscientiousness and neuroticism personality traits was also determined. Besides, investment preferences for choosing “unknown and new investment” against “known and experienced investment”, which is a typical feature of the balloon periods, were modeled with big five personality traits and motivation variables (pleasure-seeking and loss aversion) and the equation was formed. As a result, high accuracy classification success was obtained.

Originality/value
The study is unique owing to its findings. In addition, general risk aversion and risky investment intention were investigated simultaneously to explain the different findings in the literature regarding the attitude of big five personality traits to risk and personality traits that show consistent approach were identified.

Published: April 2021

Abstract

Identifying to what degree inherent characteristics of plant species and their variation in response to their environment regulate the temporal stability of plant populations is important to understand patterns of species coexistence and the stability of ecosystems. Longevity is a key characteristic of plant life history and an important component of demographic storage, but age is usually unknown for herbaceous species.

In a 12‐year‐old biodiversity experiment (Jena Experiment) comprising 80 grassland communities with six levels of plant species richness (1, 2, 4, 8, 16 and 60 species) and four levels of functional groups richness (1, 2, 3 and 4 functional groups), we studied populations of 38 dicotyledonous forb species (N = 1,683 plant individuals). The sampled individuals represented three plant functional groups (legumes, small herbs and tall herbs) and two different growth forms (species with long‐lived primary roots and clonal species with rhizomes/stolons). We assessed the age of plant individuals by means of growth ring analysis and related the age of plant populations to their temporal stability in terms of peak biomass production.

On average, plant species richness did not affect the mean age of the populations or the maximum age of individuals found in a population. Age of herbs with taproots increased and age of herbs with clonal growth decreased with increasing species richness, cancelling out each other when growth forms were analysed together. Mean population age was lowest for small herbs and highest for tall herbs, while legumes had an intermediate population age. Herbs with a taproot were on average older than herbs with a rhizome. Across all species‐richness levels, populations with older individuals were more stable in terms of biomass production over time.

Synthesis. Our study shows for the first time across multiple species that the longevity of forbs is affected by the diversity of the surrounding plant community, and that plant longevity as an important component of demographic storage increases the temporal stability of populations of grassland forb species.

AbstractXinyang Maojian tea is a kind of famous roasted green tea produced in the middle of China. Ultra‐high performance liquid chromatography‐quadrupole time of flight‐mass spectrometry (UHPLC‐Q‐TOF/MS)‐based metabolomics coupled with multivariate statistical analyses, including principal component analysis (PCA) and hierarchical cluster analysis (HCA), were carried out in XMMJTs collected from Luoshan, Shangcheng, and Shihe Counties, respectively. Additionally, seven catechins, four flavonoids, two purine alkaloids, and gallic acid contents were determined by HPLC. Differential metabolites were selected by p‐value <0.05, and fold change >1.50 or < 0.66 among 745 detected metabolites in metabolomics analysis. The results showed significant (p < 0.05) differences of three catechins including (‐)‐epicatechin, (‐)‐epicatechin gallate, and (‐)‐gallocatechin gallate, four flavonoids (i.e. quercetin, kaempferol, myricetin, and rutin), and theobromine among three various regions, and significant (p < 0.05) differences of (‐)‐epicatechin gallate, (‐)‐epigallocatechin, (+)‐catechin, gallic acid, and kaempferol between Shuchazao and Group cultivar. The HCA showed that, except for two samples (i.e. LS 2 and SH 2) of Shuchazao cultivar clustered together, others could be clustered completely according to production place. The 63 relevant differential metabolites could achieve the purpose of region identification through PCA. Kyoto encyclopedia of genes and genomes (KEGG) metabolic pathway analysis elaborated the impact of geographical origin and tea cultivar on physiological metabolism in tea tree.Practical ApplicationUltra‐high performance liquid chromatography‐quadrupole time of flight‐mass spectrometry (UHPLC‐Q‐TOF/MS)‐based liquid chromatography‐tendem mass spectrometry (LC‐MS/MS) metabolomics coupled with multivariate statistical analyses, such as principal component analysis (PCA) and hierarchical cluster analysis (HCA), revealed 63 differential metabolites related to production place, which contributed to the region identification of Xinyang Maojian teas.
Geochemistry of Rhenium and Other Trace Elements in Molybdenite, Sar Cheshmeh Porphyry Cu‐Mo Deposit, Iran
Authors: SHAFIEI BAFTI Behnam , SVOJTKA Martin , ABDOLAHI Mehdi 
Published: April 2021

AbstractLA‐ICP‐MS analysis of molybdenite from the Sar Cheshmeh porphyry Cu‐Mo deposit (PCD), Iran, shows moderate concentration of Re (average ∼207 ppm) and low concentration of chalcogenides (average of Pb + Te + Bi, ∼31 ppm) as well as metalloids (average of As + Sb + Ge, ∼4.5 ppm). The early‐formed quartz–molybdenites associated with potassic alteration are characterized by moderately low concentration of Re (21–215 ppm with an average of 83 ppm), whereas the transitional quartz–molybdenite veins related to the sericitic stage of mineralization contain more Re (62–465 ppm, with an average of 207 ppm). In contrast, the late‐formed quartz–molybdenite veins associated with phyllic alteration show the highest concentration of Re (up to 1273 ppm with an average of 395 ppm). Gradual increase in Re content of molybdenites deposited throughout the evolution of the porphyry system is probably related to elevated &#x0192;O2 and acidic conditions of the ore fluids governing the transitional and late stage of mineralization, when compared to the moderately low &#x0192;O2 and basic conditions of the ore fluids precipitating the low‐Re molybdenites associated with potassic alteration. The mixed mantle/crustal source of the ore‐related magma and its fractionated composition in Sar Cheshmeh are consistent with magmatic conditions for the formation of Mo‐rich and Re‐poor PCDs in the world.
Geochemistry and Zircon U‐Pb Dates of Felsic‐Intermediate Members of the Late Cretaceous Yüksekova Arc Basin: Constraints on the Evolution of the Bitlis–Zagros Branch of Neotethys (Elazığ, E Turkey)

Published: April 2021

AbstractDuring the Late Cretaceous in the Eastern Mediterranean, the northern branch of the southern Neotethys was closed by multiple northward subductions. Of these, the most northerly located subduction created the Baskil continental arc at around 82–84 Ma. The more southerly and intra‐oceanic subduction, on the other hand, produced an arc‐basin system, the Yüksekova Complex, as early as the late Cenomanian–early Turonian. The abundant and relatively well‐studied basaltic rocks of this complex were intruded by dykes, sills and small stocks of felsic–intermediate rocks, not previously studied in detail. The intrusives collected from five different localities in the Elazığ region of eastern Turkey are all subalkaline, with low Nb/Y values. Most of them have been chemically classified as rhyodacites/dacites, whereas a small number appear to be andesites. In normal mid‐ocean‐ridge basalt (N‐MORB)‐normalised plots, the intrusives are characterised by relative enrichments in Th and La over Nb, Zr, Hf, Ti and high field strength elements (HREEs), indicating their derivation from a subduction‐modified source. While their relatively high, positive &#x03B5;Nd(i) values (+6.4 and +7.2) might suggest a depleted mantle source for their ultimate origin, somewhat radiogenic Pb values indicate a sedimentary contribution to the source of the rocks. The overall geochemical characteristics indicate their generation in an oceanic arc setting. The zircon U‐Pb Laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) data obtained from five felsic‐intermediate rock samples yielded intrusion dates of 80–88 Ma. This suggests that the Elazığ oceanic arc‐related intrusives are slightly younger than those of the Yüksekova arc‐basin system, but coeval with the Baskil continental arc. However, the felsic–intermediate intrusives show different geochemical characteristics (oceanic arc‐type, with a lack of crustal contamination) to those of the Baskil continental arc. This indicates that these two igneous systems are unrelated and likely developed in different tectonic settings. This, in turn, supports a geodynamic model in which the northern strand of the southern Neotethys was consumed by multiple northward subductions.
The moderating role of honesty‐humility in the association of agreeableness with interpersonal competency: A study of managers in two countries

Published: April 2021

AbstractThe honesty‐humility factor from the HEXACO model of personality has been found to offer incremental validity in predicting several work‐related criteria over the remaining factors, yet its interplay with other personality factors is rarely examined. In this study, we examined how honesty‐humility (the tendency to be sincere, fair, non‐materialistic, and modest) can moderate the relation between agreeableness and interpersonal competency. Specifically, drawing on the theory of self‐concept, we proposed that agreeableness will have a stronger association with interpersonal competency among individuals who are higher on honesty‐humility, and relatively less so among individuals who are lower on honesty‐humility. Across three samples of people in managerial roles from two different cultures (Australia and Kenya), we found that honesty‐humility, indeed, moderated the agreeableness—interpersonal competency relation, both when the criterion was measured by self‐report (Sample 1, N = 167; Sample 2, N = 320; Sample 3, N = 296) and other‐report (Sample 3, N = 195). In all three samples, the positive relation of agreeableness with interpersonal competency was strongest among those who were also higher on honesty‐humility. Such an interaction effect was robust after controlling for the remaining HEXACO personality factors.

AbstractBackgroundLithium is regarded as a first‐line treatment for bipolar disorder (BD), but partial response and non‐response commonly occurs. There exists a need to identify lithium non‐responders prior to initiating treatment. The Pharmacogenomics of Bipolar Disorder (PGBD) Study was designed to identify predictors of lithium response.MethodsThe PGBD Study was an eleven site prospective trial of lithium treatment in bipolar I disorder. Subjects were stabilized on lithium monotherapy over 4 months and gradually discontinued from all other psychotropic medications. After ensuring a sustained clinical remission (defined by a score of ≤3 on the CGI for 4 weeks) had been achieved, subjects were followed for up to 2 years to monitor clinical response. Cox proportional hazard models were used to examine the relationship between clinical measures and time until failure to remit or relapse.ResultsA total of 345 individuals were enrolled into the study and included in the analysis. Of these, 101 subjects failed to remit or relapsed, 88 achieved remission and continued to study completion, and 156 were terminated from the study for other reasons. Significant clinical predictors of treatment failure (p < 0.05) included baseline anxiety symptoms, functional impairments, negative life events and lifetime clinical features such as a history of migraine, suicidal ideation/attempts, and mixed episodes, as well as a chronic course of illness.ConclusionsIn this PGBD Study of lithium response, several clinical features were found to be associated with failure to respond to lithium. Future validation is needed to confirm these clinical predictors of treatment failure and their use clinically to distinguish who will do well on lithium before starting pharmacotherapy.
Transitioning to remote learning: Lessons from supporting K‐12 teachers through a MOOC
Authors: Boltz Liz O. , Yadav Aman , Dillman Brittany , Robertson Candace 
Published: April 2021

AbstractThe recent face‐to‐face school closures due to COVID‐19 pushed teachers to quickly move their instruction online and support their students remotely. Whilst there has been a considerable push for technology integration in schools in recent years, there has been little focus on how to prepare teachers to teach online given that traditional schooling is based on a face‐to‐face delivery. As a result, many educators do not have adequate resources and preparation to support high quality and thoughtful remote learning. One way to quickly build teacher capacity is through the use of Massive Open Online Courses (MOOCs) which can provide access to professional learning at scale. In this paper, we describe a mixed methods study from a MOOC designed to provide educators with knowledge on how to support their students and create a community of learners in remote learning contexts. Specifically, we share findings on teachers’ biggest challenges of teaching remotely, perceptions of the impact of MOOC on their ability to teach remotely, and MOOC participation data. We discuss implications of these findings on the design and delivery of MOOCs for teacher professional learning, in general, but also how to develop teacher competencies for effective remote instruction.
Practitioner notesWhat is already known about this topic

Online teaching and learning is challenging for teachers without sustained support
There is not a one‐to‐one mapping of face‐to‐face pedagogical practices that translates to online teaching practices so learning to teach remotely and online is difficult
What this paper adds

Evidence that MOOCs that align with teacher needs can significantly impact educators’ perceptions of ability in teaching remotely
Evidence that MOOCs that include just‐in‐time professional learning can significantly increase the participation rates
Implications for practice and/or policy

Use of MOOCs to support teacher learning
