<p><em>Barilius bendelisis</em>, commonly known as Indian Hill Trout is an upland water fish of South East Asia. It belongs to the family Cyprinidae and dwells in shallow, clear and cold water. In this study, the intraspecific variation of <em>Barilius bendelisis,</em> on the basis of morphometric characters, was investigated. Altogether, 402 specimens were collected from four rivers in the Central Indian Himalaya. A truss network was constructed by interconnecting 12 landmarks to yield 30 distance variables that were extracted from digital images of specimens using tpsDig2 and PAST software. Allometric transformed truss measurements were subjected to univariate analysis of variance, factor analysis and discriminant analysis. All variables exhibited significant differences between the populations. Altogether 88% of the specimens were classified into their original populations (81.98% under a ‘leave-one-out’ procedure). With factor analysis measurements of the head region, the middle portion and the caudal region had high loadings on the first and second axis. The results indicated that <em>B. bendelisis</em> has significant phenotypic heterogeneity between the geographically isolated regions of Central Indian Himalaya. We hypothesize that the marked interspecific variation in <em>B. bendelisis</em> is the result of local ecological conditions.</p>

We investigated intraspecific variation of the Snowtrout, Schizothorax richardsonii on the basis of morphometric characters. Altogether, 217 specimens were collected from four rivers in the Western and Central Indian Himalaya. A truss network was constructed by interconnecting 14 landmarks to yield 31 distance variables that were extracted from digital images of specimens using tpsDig2 and PAST software. Transformed truss measurements were subjected to univariate analysis of variance, factor analysis and discriminant analysis. All variables exhibited significant differences between the populations. Altogether 86.6% of the specimens were classified into their original populations (82.9 % under a ‘leave-one-out’ procedure). With factor analysis measurements of the head region, the middle portion and the caudal region had high loadings on the on first and second axis. The results indicated that S. richardsonii has significant phenotypic heterogeneity between the Western and Central Indian Himalayas. We hypothesize that the marked interspecific variation in S. richardsonii is the result of local ecological conditions.

The present study observed variations in the morphological traits of hill trout, Barilius bendelisis (Hamilton, 1807) from Alaknanda basin of Central Himalaya. A total of 124 samples of B. bendelisis were collected from three different tributaries, Dugadda Gad, Khankhra Gad and Khandah Gad of Alaknanda river between March 2015 to April 2016. Ninety morphometric characters were measured for each specimen. Statistical tools, univariate analysis of variance (ANOVA), principal component analysis (PCA) and discriminant function analysis (DFA) were used to differentiate the populations of B. bendelisis. PCA extracted eight significant morphometric traits explaining 87.9% of total variation among the three populations. DFA revealed that 83.1% specimens were retained into their original groups. Environmental factors were attributed to phenotypic variations among closely related populations. The present study is a first attempt on stock structure of B. bendelisis from different tributaries of Alaknanda river. The study will help in future conservation and management of this fish species across Uttarakhand region, India.

Abstract Background The Family Reported Outcome Measure (FROM-16) assesses the impact of a patient’s chronic illness on the quality of life (QoL) of the patient’s partner or family members. The aim of the study was to translate, explore the structure of and validate the FROM-16. Methods The questionnaire was translated from English into German (forward, backward, four independent translators). Six interviews with family members were conducted to confirm the questionnaire for linguistic, conceptual, semantic and experiential equivalence and its practicability. The final German translation was tested for internal consistency, reproducibility and test validity. Criterion validity was tested by correlating the scores of the FROM-16 and the Global Health Scale (GHS). Principal component analysis, factor analysis, and confirmatory factor analysis was used to assess the questionnaire’s structure and its domains. Reliability and reproducibility were tested computing the intraclass correlation coefficient (ICC) using one sample t-test for testing the hypothesis that the difference between the scores was not different from zero. Results Overall, 83 family members (61% female, median age: 61 years) completed the questionnaire at two different times (mean interval: 22 days). Internal consistency was good for the FROM-16 scores (Cronbach’s α for total score = 0.86). In those with stable GHS, the ICC for the total score was 0.87 and the difference was not different from zero (p = 0.262) indicating reproducible results. A bi-factor model with a general factor including all items, and two sub-factors comprising the items from the original 2-factor construct had the best fit. Conclusions The German FROM-16 has good reliability, test validity and practicability. It can be considered as an appropriate and generic tool to measure QoL of a patient’s partner or family member. Due to the presence of several cross-loadings we do not recommend the reporting of the scores of the two domains proposed for the original version of FROM-16 when using the German version. Thus, in reporting the results emphasis should be put on the total score. Trial registration: Retrospectively registered: DRKS00021070.

Test Retest Reliability

As the first in their families to attend college, first-generation students plausibly experience family achievement guilt—socioemotional distress related to “leaving family members” to attend college. Family achievement guilt is little studied but a promising indicator of student outcomes. The present work used psychometric methods to develop the family achievement guilt scale. First-generation (46.6%) and continuing-generation (i.e., at least one parent has a 4-year degree, 53.4%) students completed a 41-item guilt measure online. Exploratory factor analysis revealed four factors, including guilt related to Leaving Family Behind, Having More Privileges, Becoming Different, and Experiencing Pressures about not being successful. The scale yielded good internal and test–retest reliability. Moreover, guilt predicted greater engagement in family roles and interdependent motives for college, even after controlling for general negative affect. In measuring guilt in psychometrically sound ways, we validate the voices of first-generation college students and alert institutions to adjust how they serve students.

Allocation Strategies

Background: In the initial coronavirus disease 2019 (COVID-19) vaccination program, prioritizing vulnerable groups is inevitable due to limited supply. Currently, most of the allocation strategies are focused on individuals’ characteristics. Objectives: The present study aimed to assess the opinions of Iranian population in specifying high-priority individuals and groups for COVID-19 vaccination. Methods: An online survey was conducted using some popular social media in Iran. The data was collected from Iranian population (878 individuals) aged 18 years and older during the COVID-19 pandemic (2 - 20 May 2020) to investigate their opinions towards vaccine allocation strategies at the family and society levels. In vaccine prioritizing within family three option and in vaccine prioritizing within society, seven population groups were introduced by the respondents in a random order, respectively. To analyze the data, mean rank and univariate analysis was used. Results: Healthcare workers, high-risk patients, and the elderly were the first priority groups for a vaccination with a mean rank of 2.8, 2.8, and 3.8, respectively. The least priority group was policymakers and executive managers (mean rank = 5.75). At the family level, 64% of the respondents introduced one of the family members as the first priority for vaccination, followed by their children (29%) and themselves (7%). No significant relationship was observed between respondents’ characteristics and their prioritization in vaccine prioritizing within society. Conclusions: Although involving public preference in decision-making is a key factor for the success of policies, careful design and implementation of vaccination programs through considering risk-benefit assessment is strongly recommended.
