Predicting plant species distributions using climate‐based model ensembles with corresponding measures of congruence and uncertainty

AbstractAimThe increasing availability of regional and global climate data presents an opportunity to build better ecological models; however, it is not always clear which climate dataset is most appropriate. The aim of this study was to better understand the impacts that alternative climate datasets have on the modelled distribution of plant species, and to develop systematic approaches to enhancing their use in species distribution models (SDMs).LocationVictoria, southeast Australia and the Himalayan Kingdom of Bhutan.MethodsWe compared the statistical performance of SDMs for 38 plant species in Victoria and 12 plant species in Bhutan with multiple algorithms using globally and regionally calibrated climate datasets. Individual models were compared against one another and as SDM ensembles to explore the potential for alternative predictions to improve statistical performance. We develop two new spatially continuous metrics that support the interpretation of ensemble predictions by characterizing the per‐pixel congruence and variability of contributing models.ResultsThere was no clear consensus on which climate dataset performed best across all species in either study region. On average, multi‐model ensembles (across the same species with different climate data) increased AUC/TSS/Kappa/OA by up to 0.02/0.03/0.03/0.02 in Victoria and 0.06/0.11/0.11/0.05 in Bhutan. Ensembles performed better than most single models in both Victoria (AUC = 85%; TSS = 68%) and Bhutan (AUC = 86%; TSS = 69%). SDM ensembles using models fitted with alternative algorithms and/or climate datasets each provided a significant improvement over single model runs.Main conclusionsOur results demonstrate that SDM ensembles, built using alternative models of the same climate variables, can quantify model congruence and identify regions of the highest uncertainty while mitigating the risk of erroneous predictions. Algorithm selection is known to be a large source of error for SDMs, and our results demonstrate that climate dataset selection can be a comparably significant source of uncertainty.

Impact of Interest Congruence on Study Outcomes.

Grounding on Holland’s RIASEC model of vocational interests and the respective assumptions on person-environment fit (congruence), this paper focuses on how congruence is related to study outcomes, especially students’ persistence, performance, and satisfaction. The paper distinguishes the measure of congruence with respect to social congruence (SOC) (interest fit with the study mates) and aspirational congruence (ASP) (interest fit with the occupation aspired) and also distinguishes the effects of congruence for gender and six different study areas including Science, Technology, Engineering, Mathematics (STEM), medicine, economics, education, and languages. The paper analyses 10,226 university freshmen of the German National Educational Panel Study (NEPS) and follows them longitudinally with respect to their study outcomes. The results show that students’ persistence was more related to SOC than to ASP, especially for male students. Furthermore, SOC was particularly important for students in STEM areas. Regarding performance, however, ASP was more important. Here, we notably found correlations for STEM subjects with a balanced proportion of female students. Regarding satisfaction, mainly marginal correlations could be found. The results indicate conceptual differences between social and aspirational congruence as well as specific effects for gender and study area. While research might take this into account by specifically developing their models for different study areas, career counseling may reflect on the different significance of the interest-based person-environment fit for different study areas. Initiatives for raising young people’s participation in STEM should therefore specifically focus on students that have high chances to develop interest profiles that are congruent to STEM rather than students who show profiles which already indicate a low congruence.

News by Popular Demand: Ideological Congruence, Issue Salience, and Media Reputation in News Sharing

Social media news sharing has become a central subject of scholarly research in communication studies. To test current theories, it is of an utmost importance to estimate the meaningful parameters of news sharing behavior from observational data. In this article, we retrieve measures of ideological congruence, issue salience, and media reputation to explain news sharing in social media. We describe how the proposed statistical model connects to different strands of the news sharing literature. We then exemplify the usefulness of the model with an analysis of the relationship between ideological congruence and issue salience. Results show that if ideology and salience correlate with each other, the preferences of ideologues (i.e., users who give higher weight to ideological congruence) will be overrepresented in observational data. This will result in the heightened perceptions of polarization. We test the performance of the model using data from Brazil, Argentina, and the United States.

Measuring Agreement: How to Arrive at Reliable Measures of Opinion Congruence Between Voters and Parties

ABSTRACT The extent to which voters and parties agree on policies is an important way through which political scientists have empirically studied political representation. This opinion congruence is most often measured by comparing preferences on a number of policy statements. While the selection of policy statements has not escaped scholarly attention, its impact on the reliability of congruence scores, i.e. the degree to which similar levels of opinion congruence are found when different samples of policy statements are used, has been less investigated. This article looks at which factors of statements samples and voters affect the reliability of congruence measures. It does so by simulating over 5 million opinion congruence scores on the basis of a dataset containing 134 voter and party policy preferences. It finds that both the number of statements and their topic diversity positively affect the reliability of congruence estimates. In addition, the congruence estimates of politically less sophisticated voters are more reliable but only when many left-right policy statements are included in the statement selection. Finally, explorative analyses suggest that increasing topic diversity also increases the validity of congruence measures.

Elastic priors to dynamically borrow information from historical data in clinical trials.

Use of historical data and real-world evidence holds great potential to improve the efficiency of clinical trials. One major challenge is to effectively borrow information from historical data while maintaining a reasonable type I error and minimal bias. We propose the elastic prior approach to address this challenge. Unlike existing approaches, this approach proactively controls the behavior of information borrowing and type I errors by incorporating a well-known concept of clinically significant difference through an elastic function, defined as a monotonic function of a congruence measure between historical data and trial data. The elastic function is constructed to satisfy a set of prespecified criteria such that the resulting prior will strongly borrow information when historical and trial data are congruent, but refrain from information borrowing when historical and trial data are incongruent. The elastic prior approach has a desirable property of being information borrowing consistent, that is, asymptotically controls type I error at the nominal value, no matter that historical data are congruent or not to the trial data. Our simulation study that evaluates the finite sample characteristic confirms that, compared to existing methods, the elastic prior has better type I error control and yields competitive or higher power. The proposed approach is applicable to binary, continuous, and survivalendpoints.

The Imperial Joint Line Congruency Measurement is a valuable tool in total knee arthroplasty

BackgroundPreservation of joint line height is an important factor in post-operative function after Total Knee Arthroplasty (TKA). This is the first study investigating the reliability of the novel Imperial Joint Line Congruency Measurement (IJLCM) technique for the assessment of joint line height using plain radiographs.MethodsThe reliability of two techniques used to measure joint line height on pre-operative and post-operative plain radiographs is presented. 120 patients that underwent TKA from 6 different international centres were included. Measurements were performed using each technique by two senior orthopaedic surgeons at two different timepoints (test-retest). Two undergraduate medical students performed joint line measurements using the most reproducible of the two techniques on 40 pre-operative and post-operative images to establish the reliability of the measurement technique.ResultsThe IJLCM demonstrated an average absolute difference of 1.83mm (CI 1.56–2.10mm) and excellent inter and intra-rater reliability between senior orthopaedic surgeons (>0.92 (CI 0.88–0.94) when measuring joint line height on plain radiographs. Overall Crohnbach’s alpha over 0.92 confirmed internal consistency. Measurements performed using the control technique as previously described by Figgie et al. had an average absolute difference of 5.75mm (5.17–6.32mm). Comparison of measurements by senior orthopaedic surgeons and medical students using the IJLCM technique with ANOVA and student’s t-test demonstrated acceptable agreement and inter-rater reliability of >0.92 (0.87–0.95).ConclusionThis study shows excellent accuracy, precision, and reliability of the novel IJLCM technique. Furthermore, excellent agreement between senior orthopaedic surgeons and medical students when using the IJLCM could be shown. The IJLCM technique is reliable for joint line assessment.

The effect of misgendering on body dissatisfaction and dietary restraint in transgender individuals: Testing a Misgendering-Congruence Process.

Despite research findings that transgender individuals have higher rates of body dissatisfaction and disordered eating than their cisgender peers, reasons for greater eating pathology remain unclear. We propose a Misgendering-Congruence Process by which being misgendered (i.e., labeled a gender other than that with which one identifies) could lead transgender individuals to feel greater incongruence between their bodies and internal identities, which in turn leads to body dissatisfaction and efforts to bring one's body in line with one's identified gender by engaging in weight and shape control behaviors such as dietary restraint. One hundred and thirty transgender individuals completed measures of misgendering frequency, transgender congruence, body dissatisfaction, and dietary restraint. Mediation analyses provided preliminary support for the Misgendering-Congruence Process when conducted with the overall sample as well as with transgender subgroups: transgender women (n=41), transgender men (n=42), and nonbinary transgender individuals (n=47). Social recognition of transgender people's gender identities appears to play a unique role in their body satisfaction and restrained eating behaviors.

Contributors to Poststroke Dysphagia-Related Caregiver Burden.

Purpose Caregiver burden negatively impacts both stroke survivor and caregiver well-being. Thus, it is important to better understand the individual- and dyadic-level variables that may contribute to dysphagia-related caregiver burden. The aim of this preliminary study was to identify survivor-, caregiver-, and dyadic-specific factors associated with burden in couples experiencing poststroke dysphagia. Method Twenty-eight stroke survivors ("care recipients") with dysphagia and their spouses ("caregivers") participated. Care recipients and caregivers completed a survey from which scores for the following variables were derived: dysphagia-related caregiver burden, survivor- and spouse-perceived impact of dysphagia on mealtimes (social, mealtime logistics), dyadic congruence on perceived impact, International Dysphagia Diet Standardisation Initiative Functional Diet Scale, Swallowing-Related Quality of Life Scale, and Stroke Impact Scale (cognitive, emotional, physical, and social domains). Spearman's rho and point biserial correlation coefficients were calculated to determine the factors related to caregiver burden. Results Increased burden was significantly associated with greater care recipient- and spouse-perceived impact of dysphagia on mealtime logistics; however, burden was not associated with measures of dyadic congruence of perceived impact. Notably, increased burden was also associated with increased diet restrictiveness and decreased swallow-specific quality of life. Dysphagia-related caregiver burden was not associated with measures of stroke impact/severity across any domain. Conclusions Factors related to dysphagia-related caregiver burden are multifactorial and include both care recipient (e.g., International Dysphagia Diet Standardisation Initiative Functional Diet Scale, Swallowing-Related Quality of Life Scale, perceived impact of dysphagia on mealtime logistics) and caregiver (e.g., perceived impact of dysphagia on mealtime logistics) variables. The results of this preliminary investigation support the need to incorporate aspects of counseling and family-centered care into our management practices, a growing area of interest for speech-language pathologists.

The three-component dimension-based model of self-brand user image congruence

ABSTRACT The existing models and methods of self-brand user image congruence measurement have taken into account desirable characteristics but mostly ignored undesirable changes in the self-image. Addressing this gap, a three-component model of self-brand user image congruence was developed based on self-regulation theory and three cardinal self-evaluation motives. The model enabled a dimension-based measurement not only of a perceived confirmatory value and a positive added value of the brand in consumer self-image, but also of its negative added value. A series of two psycholexical exploratory studies and three separate confirmatory studies established the structure of consumer-to-typical-brand-user comparisons and proved a unique contribution of each component to the explanation of brand preference. The proposed method showed better results than the existing dimension-based indirect method of congruence measurement and allowed for a precise measurement of the symbolic value of the brand for consumer self-image, which has important managerial implications. In-depth knowledge of desired and undesired self-congruence may help marketing managers in targeting consumers and positioning their brands in a better way to appeal to the audience.

Incorporating Consumer Product Categorizations into Shelf Layout Design

Using one field and two online lab experiments, this article shows that congruency between shelf layout and a consumer’s internal product categorization increases the perceived variety of the assortment and reduces the perceived complexity of the shelf layout. These assortment perceptions, in turn, heighten purchase intention and satisfaction toward the chosen item. Results are robust across internal categorization measurements (planogram design vs. sorting tasks), congruency measures (distance- vs. matching-based), and products (biscuits vs. yogurt snacks). In the field study, familiarity—operationalized as either consumption frequency or subjective product knowledge—increased the overall effect of categorization congruency and strengthened its pathway through perceived variety (vs. the one through complexity). The authors show how their research can be exploited to improve shelf layouts by optimizing the external categorization. They demonstrate the value of a unifying Bayesian framework for research on behavioral decision making that uses the same set of posterior parameter draws for parameter inference, moderated mediation analysis, and optimization under uncertainty.

Drawn to the Screen by Who We Are and Who We Aspire to Be: Brand-Self Congruence Differences in Movie Preferences

ABSTRACT Established media preference theories implicitly presume that audiences know a media product’s content or effects. Brands can fill this logical gap, with brands that media creators craft around their products providing cues about potential content or effects. Connecting parallel theories concerning self-congruence in communication and marketing research, this survey-based study examines whether individuals anthropomorphize movie product brands to have personalities and prefer those with personalities paralleling their own personality. In the process, it also introduces a novel “independent” congruence measure, where congruence is calculated between an individual’s personality as they rate themselves and a movie’s brand personality as rated by an independent sample. Results of paired t-tests and mixed ANCOVAs suggest that the previously unwatched movies individuals indicate being most likely to watch indeed have personalities more congruent to their own than do the previously unwatched movies individuals indicate being least likely to watch, while in terms of post-consumption evaluation, the movies that individuals indicated as their favorite tended to be less congruent with their personality than movies they indicated as their least favorite. Theoretical and practical ramifications are discussed.

Policy congruence and its impact on satisfaction with democracy

The relationship between what citizens want in terms of policies and what they get from political elites is considered one of the key aspects of representative democracies. Scholars have thus investigated thoroughly the state of citizen-elite congruence in advanced democracies and whether this relationship influences citizens' democratic satisfaction. These studies do show that citizens' assessment of their political system and especially their satisfaction with democracy are importantly influenced by the quality of representation and how close they are to their preferred parties or the government position. In the paper, we build on this literature and consider whether congruence between citizen preferences and policies influences citizens' satisfaction with democracy. This last stage of representation has mostly been overlooked in past research. To address this question, we make use of data from the Comparative Study of Electoral Systems (module 4). Policy congruence is measured based on respondent answers to a series of questions with respect to their preferences on public expenditure in eight policy domains. We also compare the effect of policy congruence to other conventional measures of congruence (e.g. party and government congruence). Our results indicate that this new measure of policy congruence has substantial effect on citizens’ satisfaction with democracy and more so than previous measures of ideological congruence.

How do voters perceive ideological congruence? The effects of winning and losing under different electoral rules

The degree of ideological congruence between citizens and their elected representatives is an important feature of democratic systems of government. A long tradition of literature has examined the ideological linkages between citizens and governments, often drawing attention to the differences (or lack thereof) in congruence across different types of electoral systems. Previous research has largely relied on aggregate-level measures of ideological congruence, such as the ideological distance between the position of the median voter and the government. We turn our attention here to how congruence relationships are perceived by individual voters, and how the perceptions of congruence may vary across electoral system types. This individual-level measure of ideological congruence is important in that individual-level, rather than aggregate-level, congruence has been shown to influence other outcomes such as citizen satisfaction with democratic performance. We expect electoral “winners” – those who voted for a party that entered government – to perceive greater ideological congruence between themselves and the government compared to electoral “losers”. We expect this effect to be stronger in majoritarian systems where political competition takes place primarily between two parties, than in proportional systems where electoral losers are more likely to receive a proportional share of representation. We test these expectations by estimating random-effects regressions of perceived individual-level congruence using data from 54 elections held in 23 democracies included in the Comparative Study of Electoral Systems (CSES). The results provide consistent support for our expectations. Electoral winners in all types of electoral systems perceive greater ideological congruence between themselves and the government, and this effect is stronger in majoritarian systems.

The Effect of Distal Radius Fractures on 3-Dimensional Joint Congruency

Whereas the goal of distal radius fracture treatment is anatomical restoration, controversy exists as to whether it is the severity of the disruption of joint alignment at the time of fracture or residual malalignment after healing that determines outcome. The objective of this study was to compare joint contact mechanics bilaterally a minimum of 3 years following a distal radius fracture. Our hypothesis was that 3-dimensional joint space would be reduced in individuals following wrist fracture and that these changes in joint load lead to the development of degenerative arthritis. To test the hypothesis, an interbone spacing algorithm was used to determine whether 3-dimensional joint space and contact mechanics were altered in the distal radioulnar (DRUJ) and radiocarpal joints following a wrist fracture. In 16 subjects with previous unilateral wrist fractures, 3-dimensional interbone distance (joint space), a measure of joint congruency and 3-dimensional alignment, was quantified from reconstructed computed tomography bone models of the distal radius, ulna, scaphoid, and lunate. At an average of 8 years following fracture, joint interbone spacing area was reduced in the radiolunate joint of the injured wrist in comparison with the uninjured wrist. The joint interbone spacing area was decreased in the DRUJ and radioscaphoid joint of the injured wrist compared with the uninjured wrist but this difference was not statistically significant. This study demonstrates the use of a noninvasive tool that can be used to examine joint loading and suggests that further investigation into the association between altered joint loading and the development of posttraumatic arthritis is needed, especially in the radiocarpal joints. This paper provides a noninvasive image-based framework that can be used to examine joint contact area over time and provides preliminary data examining the effect of a distal radius fracture on the joint congruency of the DRUJ and radiocarpal joints.

Construction and preliminary validation of the Cognitive and Emotional Congruence with Children (C-ECWC) Scale.

Emotional congruence with children is central in understanding why some adults pursue sexual contact with children. Although self-report scales have been developed to assess for emotional congruence with children, these scales have equivocal latent structure and less than desirable performance in validation research. Further, these scales were not developed to assess emotional congruence with children in individuals who commit Internet-facilitated offenses. In the current study, a sample of men with histories of Internet-facilitated sexual offenses, contact sexual offenses against children, and nonsexual offenses was used to examine factor structure, internal consistency, convergent and divergent validity, and known-group validity of the newly developed Cognitive and Emotional Congruence with Children (C-ECWC) scale. The scale had a three-factor latent structure, adequate internal consistency and adequately captured the nomological network of correlates and group differences anticipated for a measure of emotional congruence with children. Implications for scale validation and use in future research into emotional congruence with children are discussed. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Post-accession congruence in Bulgaria and Romania: measuring mass-elite congruence of opinions on European integration through mixed methods

This article proposes a mixed-methods measurement of the mass-elite congruence of opinions on the EU based on a combination of speech and survey data. It focuses on two countries (Bulgaria and Romania) that were known for their pro-European profile until their EU accession, but which faced many political difficulties afterwards. The analysis covers the 2013–2017 period that includes a great deal of these post-accession difficulties. The article illustrates how we can make meaningful comparisons between short-term, dichotomous mass, and elite attitudes with timeframes determined by non-electoral events.

On the choice of weights for aggregating judgments in non-negotiable AHP group decision making

We propose a formal method to compute a suitable set of coefficients and aggregate individual judgments in a common group preference matrix. In our procedure we assume that there is a large dispersion and decision makers are unwilling or unable to revise their judgments and, in any case, the weights are not negotiable. Our method, based on Frobenius norm, provides a solution which takes into account a new congruence measure between decision makers.

Developing an Athlete Brand Identity Scale using Rasch analysis

PurposeThis study identifies important dimensions of the athlete brand identity construct incorporating the athlete perspective. It also uses Rasch analysis to provide a practical tool (the Athlete Brand Identity Scale) to measure how closely an athlete's personal brand identity is aligned with their perceived brand image.Design/methodology/approachReference to existing athlete branding measurement tools and consultation with ten athlete experts generated (74) items considered important to an athlete brand. Two different response scales were then used to test those items in wider surveys of athletes and consumers. This allowed for further scale development and measurement of congruence between an athlete's self-image and the brand image held by consumers (within the same survey). Factor analysis and Rasch analysis were carried out to refine the item pool and assess item measurement properties to establish a concise scale for determining athlete brand identity.FindingsResults show successful identification of four dimensions of athlete brand identity measurement: athletic integrity, athletic success, fan engagement and character traits, informed development of the Athlete Brand Identity Scale (ABIdS). The unique and significant aspect of the ABIdS is its capacity to incorporate the athlete's perspective into brand management.Practical implicationsThe ABIdS can be utilised by early-career athletes to plan and prioritise branding efforts whilst established athletes can identify incongruence between self-image and consumer perceptions. Such gaps can be evaluated and branding activities modified accordingly. This will enable athletes to better access corporate support/sponsorship thereby reducing reliance on public funds.Originality/valueThe major difference between the ABIdS and other existing scales in the athlete brand research domain is the focus on the athlete perspective, as opposed to the consumer perspectives. Evaluating consumer perspectives does not explain how athletes perceive their own brand or how their own perception of their brand compares to that of people external to the brand (fans and consumers). The ABIdS developed in this study has the potential to achieve this objective as its design was driven by athlete perceptions but tested on both athletes and consumers.

The Emotional Attentional Blink as a Measure of Patriotism.

This study aims to explore whether the implicit processing of emotional symbols related to patriotic feeling may exert some effects on attention. Here, we have conducted an experiment using two interrelated tasks. First, we use flags with different meanings to participants for measuring the strength of the emotional attentional blink (EAB) within a rapid serial visual presentation (RSVP) paradigm. Then, we use a "congruency judgments" subjective test, where we confront participants to judge the affinity between pairs of politician leaders and flags of different sign for community participants, while recording two physiological measures (Heart Rate Variance and Galvanic Skin Response) to evaluate the variations elicited by that confrontation. Results on the EAB task show a significant emotion induced blindness for emotional stimuli representing Catalan and Spanish patriotism (α = .05), while the effect does not appear for the stimulus representing neutral patriotism. The interaction "Flags x Patriotism" was significant, F(1, 51) = 4.62; p = .036; ηp2 = .083. Results on the second task show that measures derived from electrophysiological records are sensitive to patriotic feeling, both being complementary. In addition, by using measures of congruence, the "Leaders x Flags" interaction was significant, F(3.682, 125.204) = 53.55; p < .001; ηp2 = .612. Finally, a multiple linear regression model for each emotional inductor was verified for the Catalan case, using the EAB effect as criteria, R2Adjusted = .79; p < .001. Some theoretical and methodological aspects derived of this exploratory study are discussed.

Representation in Western Europe: Connecting party-voter congruence and party goals

One of the most common critiques of political parties is that they no longer represent the interests of their voters. On one hand, representation literature tasks all parties equally to ensure high ideological congruence with their voters. On the other hand, party behaviour literature acknowledges that parties have legitimately different primary goals, in particular vote-maximisation or policy-seeking. Thus, this article analyses whether ideological congruence depends on the general goals that parties pursue. Furthermore, this article proposes a novel, distribution-based measure of party-voter ideological congruence that reduces the loss of voter information stemming from the many-to-one data relationship. This measure is applied to 470 data points from parties in 10 Western European countries from 1970 to 2009. The article finds that vote-maximising parties create higher levels of congruence than policy-seeking parties. On this basis, the article calls for evaluations of party behaviour considering party-type specificity.
