RESUMEN
Social identification denotes individuals' psychological bond with their ingroup. It is an indispensable construct in research on intragroup and intergroup dynamics. Today's understanding of social identification is firmly grounded in self-stereotyping principles (i.e., assimilation to the ingroup prototype). However, we argue for a more integrative approach to understand social identification, including a more prominent role for the personal self. We present the Integrative Model of Social Identification (IMSI) and postulate that there are two cognitive pathways to self-group overlap that can simultaneously yet distinctly explain social identification: self-stereotyping and self-anchoring (i.e., projection of personal self onto ingroup). We review different theoretical and methodological approaches to both processes and integrate them into one model. Subsequently, we empirically demonstrate the positive relationship between self-stereotyping, self-anchoring, and identification in various group contexts and individuals. In sum, our model highlights the dynamic interplay of personal and social self as cornerstones of social identification.

Data repositories, like research biobanks, seek to optimise the number of responding participants while simultaneously attempting to increase the amount of data donated per participant. Such efforts aim to increase the repository's value for its uses in medical research to contribute to improve health care, especially when data linkage is permitted by participants. We investigated individuals' motives for participating in such projects and potential reasons for their withdrawal from participation in a population-based biobank. In addition, we analysed how these motives were related to various characteristics of the participants and their willingness to permit data linkage to their personal data for research. These questions were explored using a sample of participants in the Dutch Lifelines biobank (n = 2615). Our results indicated that motives for participation and withdrawal were premised on benefits or harm to society and to the individuals themselves. Although general values and trust both played key roles in participation, potential withdrawal and willingness to permit data linkage, they were differentially associated with motives for participation and withdrawal. These findings support and nuance previous findings by highlighting the distinctiveness and complexity of decision making regarding participation in or withdrawal from data donation. We suggest some new directions for improving recruitment, retention and safeguarding strategies in biobanking. In addition, our data provide initial evidence regarding how factors may relate with the probability that individuals will agree to data linkages, when controlling for their unique effects. Future research should further investigate how perceptions of harm and benefits may influence decision making on withdrawal of participation.

Introduction Invasive breast cancer with neuroendocrine differentiation is a rare subtype of breast malignancy. Due to frequent changes in the definition of these lesions, the correct diagnosis, estimation of exact prevalence, and clinical behaviour of this entity may be challenging. The aim of this study was to evaluate the prevalence, clinical features, and outcomes in a large cohort of patients with breast cancer with neuroendocrine differentiation. Patients Twenty-seven cases of breast cancer with neuroendocrine differentiation have been included in this analysis. Twenty-one cases were identified by systematic immunohistochemical re-evaluation of 465 breast cancer specimens using the neuroendocrine markers chromogranin A and synaptophysin, resulting in a prevalence of 4.5%. A further six cases were identified by a review of clinical records. Results Median age at the time of diagnosis was 61 years. 70% of patients had T2â-â4 tumors and 37% were node-positive. The most common immunohistochemical subtype was HR-positive/HER2-negative (85%). 93% were positive for synaptophysin and 48% for chromogranin A. Somatostatin receptor type 2A status was positive in 12 of 24 analyzed tumors (50%). Neuroendocrine-specific treatment with somatostatin analogues was administered in two patients. The 5-year survival rate was 70%. Conclusions Breast cancer with neuroendocrine differentiation is mostly HR-positive/HER2-negative and the diagnosis is made at a higher TNM stage than in patients with conventional invasive breast carcinoma. Moreover, breast cancer with neuroendocrine differentiation was found to be associated with impaired prognosis in several retrospective trials. Due to somatostatin receptor 2A expression, somatostatin receptor-based imaging can be used and somatostatin receptor-targeted therapy can be offered in selected cases.
RESUMEN
What role does intergroup contact play in promoting support for social change toward greater social equality? Drawing on the needs-based model of reconciliation, we theorized that when inequality between groups is perceived as illegitimate, disadvantaged group members will experience a need for empowerment and advantaged group members a need for acceptance. When intergroup contact satisfies each group's needs, it should result in more mutual support for social change. Using four sets of survey data collected through the Zurich Intergroup Project in 23 countries, we tested several preregistered predictions, derived from the above reasoning, across a large variety of operationalizations. Two studies of disadvantaged groups (Ns = 689 ethnic minority members in Study 1 and 3,382 sexual/gender minorities in Study 2) support the hypothesis that, after accounting for the effects of intergroup contact and perceived illegitimacy, satisfying the need for empowerment (but not acceptance) during contact is positively related to support for social change. Two studies with advantaged groups (Ns = 2,937 ethnic majority members in Study 3 and 4,203 cis-heterosexual individuals in Study 4) showed that, after accounting for illegitimacy and intergroup contact, satisfying the need for acceptance (but also empowerment) is positively related to support for social change. Overall, findings suggest that intergroup contact is compatible with efforts to promote social change when group-specific needs are met. Thus, to encourage support for social change among both disadvantaged and advantaged group members, it is essential that, besides promoting mutual acceptance, intergroup contact interventions also give voice to and empower members of disadvantaged groups.

Migration elicits mixed reactions from the host-society. Negative responses towards migrants seem to emerge when migrants are perceived as culturally different. We investigated when and why perceived cultural distance (PCD) is associated with negative migrant attitudes by focussing on differences in cultural values. We expected that PCD in social values (focus on relationships and society) should be more strongly associated with attitudes towards migrants than personal values (individual needs and gains) and should be mediated by symbolic threat. In two quasi-experimental studies (N = 200, N = 668) with Dutch participants (host-society), we simultaneously tested effects of respondents' perception of Dutch values, their perceptions of migrant values (of Moroccan, Syrian, Polish ethnic origin), and PCD between Dutch-migrant value on attitudes. For all migrant groups, PCD in social values was associated with more negative attitudes, less tolerance, and less policy support regarding migrants; this was mediated by symbolic threat. These links were weaker for personal values.

Research in genetics relies heavily on voluntary contributions of personal data. We aimed to acquire insights into the differences between participants and refusers of participation in a Dutch population-based biobank. Accordingly, we assessed the demographic and prosocial intrapersonal characteristics of respondents who participated (n = 2615) or refused to participate (n = 404) in the Lifelines biobank and databank. Our results indicated that health-related values critically influence participation decisions. The participation threshold for Lifelines was determined by an absence of health-related values and of trust in government. Therefore, considering these factors in communication and recruitment strategies could enhance participation in biomedical research. No indications were found of a stronger general prosociality of participants or their trust in researchers beyond the context of biobanking. This emphasizes the contextual understanding of the decision of participation in biobanking. Our findings may contribute to improving recruitment strategies by incorporating relevant values and/or highlighting prosocial benefits. Moreover, they foreground the need to address trust issues in collaborations between data repositories and commercial companies. Future research should explore how prosocial intrapersonal characteristics drive participation and withdrawal decisions and relate to contextual attributes.

Linguistically similar neighbouring nations that differ in size are often asymmetrical in their attitudinal relations towards each other: Citizens of smaller nations tend to see larger nations as less likeable and less similar than vice versa. We hypothesized that the smaller nations' reaction is the consequence of a threatened identity due to its relative size combined with too much similarity on a vital part of its identity, namely language. To test this hypothesis, 832 high-school students from six different ethnic/national entities (France, Germany, Austria, the French- and German-speaking parts of Switzerland, the French- and Dutch-speaking parts of Belgium, and The Netherlands) completed a questionnaire on liking and similarity ratings. The results-to a large extent-showed that differences in size, in combination with linguistic similarity with another nation, pose a threat to the identity of the smaller nation or ethnic group. Differences in size, in combination with linguistic similarity, were associated with asymmetries in mutual liking on one hand and asymmetrical perceptions of similarity to the other country on the other hand. The conclusions of this study are consistent with findings of earlier research and stress the importance of language for a nation's identity. Moreover, the findings support social identity theory as a useful theory for understanding intergroup and international relations. Les nations voisines linguistiquement similaires qui diffèrent en taille sont souvent asymétriques dans leurs relations attitudinales l'une envers l'autre: les citoyens des nations plus petites tendent à voir les nations plus grandes comme moins sympathiques et moins semblables et vice-versa. Notre hypothèse était que la réaction des nations plus petites est la conséquence d'un sentiment de menace à l'identité dû à leur taille réduite combinée avec trop de similitudes concernant une partie vitale de leur identité: c'est-à-dire le langage. Pour tester cette hypothèse, 832 étudiants collégiaux issus de six ethnies/nationalités différentes (la France, l'Allemagne, l'Autriche, la Suisse romande et allemande, la Belgique française et néerlandaise, les Pays-Bas) ont complété un questionnaire sur les taux de sympathie et de similitude. Les résultats ont indiqué que les différences en taille en combinaison avec la similitude linguistique avec une autre nation représentent une menace pour l'identité de la nation ou du groupe ethnique plus petit. Les différences en taille en combinaison avec la similitude linguistique étaient associées, d'une part, avec des asymétries dans la sympathie mutuelle et, d'autre part, avec des perceptions asymétriques de similitude avec l'autre nation. Les conclusions de cette étude sont en accord avec les résultats des études antérieures et soutiennent l'importance du langage pour l'identité d'une nation. De plus, les résultats appuient l'utilité de la théorie de l'identité sociale pour comprendre les relations intergroupes et internationales. Naciones vecinas con similitudes lingüísticas pero que difieren en tamaño son frecuentemente asimétricas respecto de sus relaciones actitudinales una respecto de la otra. Los cuidadanos de naciones pequeñas tienden a ver a naciones más grandes como menos simpáticas y parecidas que viceversa. Nosotros hipotetizamos que la reacción de las naciones más pequeñas es la consequencia de una identidad amenazada debido a su menor tamaño combinada con una similitud muy grande relacionada con una parte vital de su identidad: es decir el lenguaje. Para probar esta hipótesis 832 alumnos de la escuela secundaria de seis diferentes grupos étnicos/nacionales (Francia, Alemania, Austria, regiones en Suiza en las que se habla francés y alemán, regiones en Bélgica en las que se habla francés y holandés así como los Países Bajos) completaron un cuestionario sobre gustos y similitudes. Los resultados mostraron - en alto grado - que las diferencias en el tamaño en combinación con las similitudes lingüísticas con otras naciones, se asocian con la amenaza de la identidad de las naciones o grupos étnicos más pequeños. Las diferencias en tamaño en combinación con las similitudes lingüísticas estuvieron asociadas con asimetrías repecto del aprecio mutuo por un lado, así como por otro lado, con percepciones asimétricas de similitud con el otro país. Las conclusiones de este estudio son consistentes con los descubrimientos de estudios previos y recalcan la importancia del lenguaje en la identidad de una nación. Adicionalmente estos resultados soportan la Teoría de la Identidad Social como una teoría útil en la comprensión de las relaciones entre grupos así como a nivel de las relaciones internacionales.

Research has mainly studied women's empowerment assessing personal (e.g., self-esteem) or relational (e.g., decision-making) empowerment indicators. Women are not isolated individuals; they are embedded in social relationships. This is especially relevant in more collectivist societies. The current research provides a relational perspective on how husbands may hamper women's empowerment by inflicting intimate partner violence (IPV) assessing women's self-reported experience. We tested the link between self-esteem and experienced IPV on financial intra-household decision-making power among women entrepreneurs (N = 1,347) in Northern Vietnam, a collectivistic society undergoing economic development. We report two measurement points. As expected, self-esteem (and not IPV) was positively related to more power in intra-household decision-making on small expenditures, which are traditionally taken by women. However, IPV (and not self-esteem) was related to less decision-making power on larger expenditures, traditionally a domain outside women's power. We test and discuss the directionality of the effects and stress the importance of considering women's close relationship when investigating signs of women's empowerment.

Exponential increases in digital data and calls for participation in human research raise questions about when and why individuals voluntarily provide personal data. We conducted 36 in-depth interviews with ex-participants, participants, and nonparticipants in a biobank to identify key factors influencing trust in centralized large-scale data repository for human research. Our findings indicated that trust depends strongly on whether such data repository benefits the public, the interests of data collectors, the characteristics of the collected data, and application of informed consent for retaining control over personal data. Concerns about the aims and range of data repository appeared to influence withdrawal of participation. Our findings underscore ethical and practical issues relating to data collection and consent procedures in human research.

When thwarted goals increase endorsement of violence, it may not always reflect antisocial tendencies or some breakdown of self-regulation per se; such responses can also reflect an active process of self-regulation, whose purpose is to comply with the norms of one's social environment. In the present experiments (total N = 2,145), the causal link between thwarted goals and endorsement of violent means (guns and war) was found to be contingent on perceptions that violence is normatively valued. Experiments 1-3 establish that thwarted goals increase endorsement of violence primarily among U.S. adults of a lower educational background and/or men who endorse a masculine honor culture. Experiment 4 manipulates the perceived normative consensus of college educated Americans, and demonstrates that thwarted goals increase college educated Americans' endorsement of whatever norm is salient: prowar or antiwar. Generalizing the model beyond violent means, Experiment 5 demonstrates that goal-thwarted Europeans report increased willingness to volunteer for refugee support activities if they perceive strong social norms to volunteer. Altogether, these findings support a frustration-affirmation model rather than frustration-aggression, whereby thwarted goals increase compliance with perceived norms for behavior, which can increase endorsement of violent means such as guns and war, but also nonviolent charitable actions.

Guided by the early findings of social scientists, practitioners have long advocated for greater contact between groups to reduce prejudice and increase social cohesion. Recent work, however, suggests that intergroup contact can undermine support for social change towards greater equality, especially among disadvantaged group members. Using a large and heterogeneous dataset (12,997 individuals from 69 countries), we demonstrate that intergroup contact and support for social change towards greater equality are positively associated among members of advantaged groups (ethnic majorities and cis-heterosexuals) but negatively associated among disadvantaged groups (ethnic minorities and sexual and gender minorities). Specification-curve analysis revealed important variation in the size-and at times, direction-of correlations, depending on how contact and support for social change were measured. This allowed us to identify one type of support for change-willingness to work in solidarity- that is positively associated with intergroup contact among both advantaged and disadvantaged group members.

RESUMEN
In this exploratory study, we present findings from semi-structured interviews with 11 self-identified lesbian and gay (LG) humanitarian aid workers of Doctors without Borders (MSF). We investigate their perceptions of workplace inclusion in terms of perceived satisfaction of their needs for authenticity and belonging within two organizational settings, namely office and field. Through our combined deductive and inductive approach, based on grounded theory, we find that perceptions of their colleagues' and supervisors' attitudes and behaviors, as well as organizational inclusiveness practices play a role in LGs' perceived authenticity, but not belonging, in the workplace. However, these organization-level characteristics do not account for between-participant differences in perceived authenticity. Therefore, we inductively construct a typology of three groups, which we coined conscious first-missioners, authentic realists, and idealistic activists, based on how LG humanitarian aid workers assess and deal with not being able to be their authentic selves when they are in the field, because homosexuality is illegal in many project countries. Conscious first-missioners are separated from the other two groups based on having gone to the field once, whereby they felt in control over the decision on how to manage their sexuality. Alternatively, authentic realists and idealistic activists alike felt they did not really have a choice in how to manage their sexuality, but handled that differently. We find the importance of one's sexuality as well as adherence to the overarching organizational mission relevant individual-level factors herein. Furthermore, we find disclosure of sexual identity to be strongly context-dependent, as participants are 'out of the closet' in the office, but go back into the closet when they enter the field, with different country contexts even leading to different decisions concerning self-disclosure, thus demonstrating the importance of careful sexual identity management. This so-called disclosure dilemma, we find, may not be merely an individual choice, but rather a shared dilemma involving multiple stakeholders, such as the organization and fellow team members. We discuss the findings' contributions to existing literature on LGs' workplace experiences and implications for future research on inclusion of sexual and other invisible minorities in the workplace.
RESUMEN
Women's empowerment is an important goal in achieving sustainable development worldwide. Offering access to microfinance services to women is one way to increase women's empowerment. However, empirical evidence provides mixed results with respect to its effectiveness. We reviewed previous research on the impact of microfinance services on different aspects of women's empowerment. We propose a Three-Dimensional Model of Women's Empowerment to integrate previous findings and to gain a deeper understanding of women's empowerment in the field of microfinance services. This model proposes that women's empowerment can take place on three distinct dimensions: (1) the micro-level, referring to an individuals' personal beliefs as well as actions, where personal empowerment can be observed (2) the meso-level, referring to beliefs as well as actions in relation to relevant others, where relational empowerment can be observed and (3) the macro-level, referring to outcomes in the broader, societal context where societal empowerment can be observed. Importantly, we propose that time and culture are important factors that influence women's empowerment. We suggest that the time lag between an intervention and its evaluation may influence when empowerment effects on the different dimensions occur and that the type of intervention influences the sequence in which the three dimensions can be observed. We suggest that cultures may differ with respect to which components of empowerment are considered indicators of empowerment and how women's position in society may influence the development of women's empowerment. We propose that a Three-Dimensional Model of Women's Empowerment should guide future programs in designing, implementing, and evaluating their interventions. As such our analysis offers two main practical implications. First, based on the model we suggest that future research should differentiate between the three dimensions of women's empowerment to increase our understanding of women's empowerment and to facilitate comparisons of results across studies and cultures. Second, we suggest that program designers should specify how an intervention should stimulate which dimension(s) of women's empowerment. We hope that this model inspires longitudinal and cross-cultural research to examine the development of women's empowerment on the personal, relational, and societal dimension.
RESUMEN
Smith and collaborators presented strong response time evidence for overlapping mental representations of the self and relevant ingroups, and they interpreted their findings as reflecting that people define themselves in terms of their ingroups. Besides on inferences from ingroup to self (self-stereotyping) however, self-ingroup overlap could also be based on inferences from the self to the ingroup (self-anchoring). The present research tackled this interpretational ambiguity and empirically distinguished self-anchoring versus self-stereotyping as processes possibly under-lying self-ingroup overlap. Results from three studies revealed stronger evidence for inferences from self to ingroup (selfanchoring) than the other way round (self-stereotyping).

Employees of merging organizations often show resistance to the merger. The employees' support depends on the companies' premerger status and on the merger pattern. Based on an intergroup perspective, three studies were conducted to investigate the influence of premerger status (high, low) and merger pattern (assimilation, integration-equality, integration-proportionality, transformation) on participants' support for a pending organizational merger. Students (Study 1) and employees (Study 2) had to take the perspective of employees of a fictitious merging organization. Study 3 investigated students' perceptions of a potentially pending university merger using a 2 (status) x 3 (merger pattern: assimilation, integration-equality, integration-proportionality) design. Across all studies, the low-status group favored integration-equality and transformation whereas the high-status group preferred integration-proportionality and assimilation. Perceived threat mediated the effects. Legitimacy was a stronger mediator for effects of the low-status group.

In the present article, we propose a dynamic model of the longitudinal predictors and consequences of ingroup identification among newcomers to a social category. We hypothesize a shift in the relative importance of intragroup affiliation as compared with intergroup differentiation for ingroup identification. Two longitudinal studies confirm the theoretical model assessing cross-sectional and longitudinal relationships between ingroup identification and interpersonal attraction, self-prototypicality, and ingroup favoritism at three measurement points during the first 4 months of group membership in two different social categories. Results demonstrate that in the initial phases of group membership, ingroup identification is mainly determined by intragroup affiliation (interpersonal attraction) and that ingroup favoritism starts playing a relevant role later on, when category membership has been established.

In times of economic downturn, perceived realistic intergroup threats (e.g., labour competition) often dominate political and media discourse. Although local outgroups (e.g., local immigrants) can be experienced as sources of realistic threats, we propose that such threats can also be perceived to be caused by distant outgroups (e.g., European Union members perceiving Greece to threaten their economies) and that such distant threats can carry over into local intolerance (e.g., increasing intolerance towards local immigrant groups). We predicted and found in two studies that perceived distant realistic threats carried over into local intolerance via two different pathways. First, direct reactions towards the distant outgroup can generalize to culturally similar local outgroups (the group-based association pathway). Secondly, Study 2 indicated that when the distant threat was attributed to stereotypical outgroup traits (e.g., being lazy), distant realistic threats activated local realistic threats, which subsequently influenced local intolerance (the threat-based association pathway). Taken together, our studies indicate that perceived realistic threats foreign can turn domestic, but in two different ways.

Majority members often react negatively to efforts to stimulate diversity. An important reason for this is that in diverse groups, majority members' own group bond is typically based on perceived prototypicality, which serves to disregard those who are different. In the present research we investigate how majority members' pro-diversity beliefs may be enhanced, by experimentally manipulating how the self is cognitively defined in relation to a diverse group. Specifically, we hypothesize that majority members' focus on the personal self (i.e., self-anchoring) rather than the social self (i.e., self-stereotyping) when creating a group bond may facilitate their pro-diversity beliefs and positive attitudes toward minority members. In two experiments we manipulated self-anchoring and self-stereotyping via mindset priming among ethnic majority members in diverse teams. As expected, results showed that relative to self-stereotyping, majority members' self-anchoring enhanced pro-diversity beliefs and positive attitudes toward minority members.

Upon joining a new social category, group members strive to establish and maintain high social identification. Thus far, we know relatively little about the cognitive underpinnings of social identification when developing from a new to a well-established group member. This research investigates the differential impact of newcomers' self-stereotyping (i.e., assimilation of the self to group stereotypes) and self-anchoring (i.e., projection of self-attributes onto the ingroup) on the development of social identification over time. Across two time points during the academic year, first year psychology students (N = 123) filled in a questionnaire on their perceptions about the self, psychology students, and social identification. Cross-sectional and longitudinal analyses confirmed our hypotheses that self-anchoring instigated new group members' social identification, while self-stereotyping instigated social identification once group membership was more well-established. This research emphasizes the interactive role of the personal and social self in the development of social identification.
