The Local Minima Problem in Hierarchical Classes Analysis: An Evaluation of a Simulated Annealing Algorithm and Various Multistart Procedures 总被引:2,自引:1,他引:1
Hierarchical classes models are quasi-order retaining Boolean decomposition models for N-way N-mode binary data. To fit these models to data, rationally started alternating least squares (or, equivalently, alternating
least absolute deviations) algorithms have been proposed. Extensive simulation studies showed that these algorithms succeed
quite well in recovering the underlying truth but frequently end in a local minimum. In this paper we evaluate whether or
not this local minimum problem can be mitigated by means of two common strategies for avoiding local minima in combinatorial
data analysis: simulated annealing (SA) and use of a multistart procedure. In particular, we propose a generic SA algorithm
for hierarchical classes analysis and three different types of random starts. The effectiveness of the SA algorithm and the
random starts is evaluated by reanalyzing data sets of previous simulation studies. The reported results support the use of
the proposed SA algorithm in combination with a random multistart procedure, regardless of the properties of the data set
under study.

Research suggests that perceptions of organizational politics consistently result in negative outcomes for individuals. In
the current study, distributive and procedural justice are explored for their effects on the relationships between perceptions
of organizational politics and turnover intentions and job satisfaction. We tested these relationships in a sample of 311
employees of a water management district. Results indicated the politics––turnover intentions and politics––job satisfaction
relationships were weaker when perceptions of both forms of justice are high. Further, and potentially more interestingly,
politics mattered the most when the distribution of outcomes was unfair (distributive justice) as opposed to when procedures
were unfair (procedural justice). Implications for future research and management practice are discussed. 相似文献

The Multicultural Counseling and Psychotherapy Test (MCPT), a measure of multicultural counseling competence (MCC), was validated in 2 phases. In Phase 1, the authors administered 451 test items derived from multicultural guidelines in counseling and psychology to 32 multicultural experts and 30 nonexperts. In Phase 2, the authors administered the top 50 discriminative items to licensed mental health professionals (N = 227) and compared MCPT scores to external indicators of MCC. Evidence was found for the construct validity and internal consistency reliability of the MCPT. El Test de Consejería Multicultural y Psicoterapia (MCPT, por sus siglas en inglés), una medida de la competencia en consejería multicultural (MCC, por sus siglas en inglés) fue validado en dos fases. En la Fase 1, los autores administraron 451 elementos del test derivados de las pautas multiculturales en consejería y psicología a 32 expertos multiculturales y 30 no expertos. En la Fase 2, los autores administraron los 50 elementos más discriminativos a profesionales licenciados de la salud mental (N = 227) y compararon los puntajes del MCPT con indicadores externos de MCC. Se hallaron evidencias de la validez del constructo y la fiabilidad de la consistencia interna del MCPT. 相似文献

Mary Foote (1872‐1968) was a successful early twentieth century American artist who suddenly closed her New York studio in 1926 to go to Zurich to study with Jung. There she joined his ‘Interpretation of Visions’ seminars (1930‐1934), which she recorded and edited. This work won Jung's praise and his friendship, but all too often Foote was seen merely as a secretary or background figure. Deirdre Bair's biography of Jung suggested that Foote's life and work deserved fuller study, if only to rebalance our view of Jung's early women followers. This paper takes up that work to ask how Foote's early life and career led to her important work in preserving and describing Jung's earliest attempts to apply his theories to clinical practice. 相似文献

POSTPARTUM BONDING DIFFICULTIES AND ADULT ATTACHMENT STYLES: THE MEDIATING ROLE OF POSTPARTUM DEPRESSION AND CHILDBIRTH‐RELATED PTSD 下载免费PDF全文

Despite decades of research demonstrating the role of adult attachment styles and early mother–infant bonding in parenting behaviors and maternal mental health, these constructs have seldom been studied together. The present study aimed to investigate the relationship between attachment styles and specific bonding difficulties of mothers. In addition, as postpartum depression and childbirth‐related posttraumatic stress symptoms have been associated with both constructs, we explored their possible mediation effect. One hundred fourteen mothers, 4 to 12 weeks’ postpartum, completed a demographic questionnaire, the Adult Attachment Style Questionnaire (M. Mikulincer, V. Florian, & A. Tolmacz, 1990), the Postpartum Bonding Questionnaire (L.F. Brockington, C. Fraser, & D. Wilson, 2006), the Modified Perinatal Posttraumatic Stress Disorder Questionnaire (J.L. Callahan, S.E. Borja, & M.T. Hynan, 2006), and the Edinburgh Postnatal Depression Scale (J.L. Cox, G. Chapman, D. Murray, & P. Jones, 1996), using an online survey system. As predicted, insecure attachment styles were associated with bonding difficulties wherein anxious/ambivalent attachment was associated with greater infant‐focused anxiety, mediated by postpartum depression but not childbirth‐related PTSD symptoms. In contrast, greater avoidant attachment style was associated with greater rejection and anger, mediated by childbirth‐related posttraumatic stress disorder (PTSD), but not depression symptoms. The current study confirmed the association of different attachment styles with bonding as well as the mediating roles of childbirth‐related PTSD and postpartum depression symptoms. Future psychological interventions may utilize such evidence to target interventions for bonding disorders in accordance with individual differences. 相似文献

PREGNANT WOMEN'S RECOLLECTIONS OF EARLY MATERNAL BONDING: ASSOCIATIONS WITH MATERNAL–FETAL ATTACHMENT AND BIRTH CHOICES 下载免费PDF全文

Recollections of own maternal care measured by parental bonding were found to be important in the pregnant woman's construction of herself as a mother. Although these recollections were studied with regard to various variables, there is a dearth of studies associated with pregnancy and childbirth. In this cross‐sectional study, 341 pregnant women were recruited. Measures included a Sociodemographics–Obstetric History Questionnaire; the Childbirth Choices Questionnaire (H. Preis, M. Gozlan, U. Dan, & Y. Benyamini, 2018); the Parental Bonding Instrument (G. Parker, H. Tupling, & L.B. Brown, 1979); a question regarding the planned presence of the woman's mother at delivery; and the Maternal‐Fetal Attachment Scale (M.S. Cranley, 1981). Parental recollections of Care were associated with fewer natural birth choices (hence, a more “medicalized” delivery), lower maternal–fetal attachment, and a wish for the mother's mother to be present at the birth. Parental recollections of Encouragement of Behavioral Freedom in childhood were associated with more natural choices regarding childbirth. In addition, women with higher scores on the parental bonding Denial of Autonomy factor reported stronger maternal–fetal attachment. Thus, early recollections of experiences with caregivers as manifested in parental bonding may be a possible influence on the transition to motherhood, and working through possible difficulties associated with these recollections may improve adjustment to motherhood. 相似文献

Ongoing scholarship in multicultural counseling practice has established the significance of microaggressions in the lived experience of clients and in the client–counselor dyad. Grounded in new research into the embodied experience of oppression, this article reviews key concepts in nonverbal communication and traumatology to illustrate how the body is implicated in the transmission of microaggressions and how counselors can become more attentive, informed, and responsive to how social power differences manifest in the body. Las investigaciones actuales sobre la práctica de la consejería multicultural han establecido la importancia de las microagresiones en la experiencia vital de los clientes y en la díada cliente–consejero. Fundamentado en nuevas investigaciones sobre la experiencia corporal de la opresión, este artículo revisa conceptos clave de la comunicación no verbal y la traumatología para ilustrar cómo el cuerpo está involucrado en la transmisión de microagresiones y cómo los consejeros pueden tornarse más atentos, informados y sensibles a cómo las diferencias de poder social se manifiestan en el cuerpo. 相似文献

This paper explores how we can make our own mythological version of ‘Jung’ say whatever we want. Excessive veneration gets in the way of his theories being allowed to stand on their own. Understanding ‘Jung’ as a mythologem provides a way out of this intoxication with identification by letting us recollect and re‐connect to the Collective Unconscious. 相似文献

Predictors of Engagement in Family Mediation and Outcomes for Families that Fail to Engage 下载免费PDF全文
An important limitation to the effectiveness of family mediation in assisting separated parents is parents failing to engage in the mediation process. In 524 parents who presented to a telephone‐based mediation service, 113 (22%) initiating parents withdrew from mediation before the other parent was invited to participate, 241 (46%) initiating parents had respondent parents who declined to participate in mediation, and 170 cases (33%) completed mediation. We tested whether socio‐demographic variables, psychological distress, coparental acrimony, parenting problems, or children's behavioral difficulties predicted mediation engagement. High interparental acrimony predicted failure to engage in mediation, but none of the other variables predicted mediation engagement. We followed a sample of 131 families that did not mediate and found they showed elevated psychological distress, acrimony, parenting problems and child adjustment difficulties, which remained unchanged 6 months later. Further research is needed to explore strategies to enhance respondent parent engagement with mediation, and to address the negative outcomes for those separated families not proceeding with mediation. 相似文献
