The Continuous Assessment of Interpersonal Dynamics (CAID) is an observational coding method that enables continuous tracking of warmth and dominance in both members of a dyad as an interaction unfolds. Research using this tool has revealed dynamic patterns relevant to psychopathology and psychotherapy, suggesting considerable potential for clinical assessment and research. However, CAID data are sensitive to a variety of person and situational factors, and the way that these factors combine to influence CAID data is poorly understood. We examined data from ten raters using CAID to assess moment-to-moment warmth and dominance in opposite-sex married dyads (N = 137 couples) interacting in four distinct situations. Using Generalizability Theory methods, we decomposed sources of variance in CAID data and estimated multiple forms of between- and within-person reliability. Results revealed how spouses’ moment-to-moment behaviors varied as a function of person, sex, dyad, rater, situation, and relevant interactions between these factors. Based on these results, we provided guidelines for interpreting CAID data at different levels of aggregation in clinical research and practice.

The purpose to determine the level of expression in the oral fluid of matrix metalloproteinases (MMPs) of types 2, 8 and 9, as well as their tissue inhibitors (TIMPs) of types 1 and 2, depending on the presence or absence of a number of components of the dental status.Material and methods. The results of a study of the level of expression of oral fluid biomarkers of 19 patients with different levels of dental health who do not have a history of history are presented. Previously, a dental examination of patients was carried out and the occurrence of signs of dental status was determined.Results and discussion. Analysis of expression levels of matrix metalloproteinases and their tissue inhibitors showed significant differences in performance.Conclusions. The data obtained suggest a significant impact of the state of dental health mainly on the level of MMP-2 and MMP-9, the indicators of which differ 2 times from the same in the opposite sex, with other conditions being almost the same (age, general health).

Case Based

This paper presents an account of field research into case-based learning in a management course, guided by the questions: ‘what is making change in this setting’, and ‘where is learning located’. Multiple forms of relations between human and nonhuman entities were identified through extensive research, which, analytically does not sit well with more traditional understandings of learning or case-based learning. A critique of those understandings is offered, drawing on concepts from post-modernism and adopting sensibilities from actor-network theory, follow the action in the setting. The authors demonstrate that the case is an assemblage of heterogeneous connections that are made by the teacher and then by the students in the classroom. In working with ANT sensibilities, examination found that tracing the action offers radically different accounts and possibilities for education research and practice. The pragmatic issues in following the action and the challenge of staying coherent and ambivalent are acknowledged.

We assessed the association of personality pathology with romantic couples' observed interpersonal behaviors. Couples engaged in four discussion tasks, after which observers used the Continuous Assessment of Interpersonal Dynamics method to continuously rate each participant's dominance and warmth over the course of each discussion. Using these ratings, we derived indices of average behaviors and changes in behaviors over the course of discussions. Generally, results indicated that the more personality pathology either spouse reported, the colder husbands were on average, and the colder they became toward their wives over time. However, personality disorder symptoms and overall interpersonal problems were largely unassociated with wives' behaviors. Results also indicated that the more dominance-related problems husbands and wives reported, the more dominantly and coldly they behaved, the more submissive or withdrawn their partners were, and the colder wives became over time; and the more warmth problems wives reported, the more dominantly, they behaved.

Confirmatory Factor

This study notes that the lack of convergent and discriminant validity of assessment center ratings in the presence of content-related and criterion-related validity is paradoxical within a unitarian framework of validity. It also empirically demonstrates an application of generalizability theory to examining the convergent and discriminant validity of assessment center dimensional ratings. Generalizability analyses indicated that person, dimension, and person by dimension effects contribute large proportions of variance to the total variance in assessment center ratings. Alternately, exercise, rater, person by exercise, and dimension by exercise effects are shown to contribute little to the total variance. Correlational and confirmatory factor analyses results were consistent with the generalizability results. This provides strong evidence for the convergent and discriminant validity of the assessment center dimension ratings–a finding consistent with the conceptual underpinnings of the unitarian view of validity and inconsistent with previously reported results. Implications for future research and practice are discussed.

Purpose This study aims to review the existing literature on corporate-level strategy to develop a conceptual framework of the headquarters’ roles as well as situational factors influencing them. Design/methodology/approach The systematic review is conducted. Accordingly, 598 studies (published from 1962–2018) were extracted from three databases (ProQuest, EBSCO and Web of Science). Then, after screening and ensuring the quality by the TAPUPAS checklist, 53 articles were systematically analyzed by manual coding method. Findings In total, 31 interventions in the form of four roles, namely, “value creation,” “value reduction,” “portfolio management“ and “loss prevent“ were identified for headquarters (HQ). Furthermore, four influencing situational factors distinguish “business characteristics,” “headquarters characteristics,” “corporate company characteristics” and “characteristic of the HQ-subsidiary relationships.” Originality/value The value of this research can be outlined as: mapping the cutting edge on the topic and systematizes the current knowledge; presenting an integrative, unique conceptual framework of HQs’ roles and influences, and particularly, of situational factors that determine the consequents of the interventions; and producing practical insights for corporate parent managers considering the situational factors influencing HQs’ roles and influences in managing their business portfolio successfully.

Embedding information into a printed image is useful in many aspects, in which reliable channel encoding/decoding systems are crucial, since there is information loss and error propagation during transmission. Circular coding is a general twodimensional channel coding method that allows data recovery with only a cropped portion of the code, and without the knowledge of the carrier image. While some traditional methods add redundancy bits to extend the length of the original massage length, this method embeds message into image rows in a repeated and shifted manner with redundancy, then uses the majority votes of the redundancy bits for recovery. In this paper, we developed a closed-form formula to predict its decoding success rate in a noisy channel under various transmission noise levels, using probabilistic modeling. The theoretical result is validated with simulations. This result enables the optimal parameter selection in the encoder and decoder system design, and decoding rate prediction with different levels of transmission error.

Social Association

The neolithic communities of central Anatolia are generally reconstructed as being constituted by relatively autonomous and homologous households occupying discrete residences and performing most domestic activities in the house. In this reconstruction households are seen as the uniform and unproblematic basic component of society. This paper aims to problematize this modular conception of central Anatolian Neolithic societies, and wants to draw attention to the multiple forms in which households occurred and the manner in which they were embedded in larger social associations. It is argued that different levels of social association can only be understood in relation to each other. Further, the manner in which social configurations in central Anatolia changed over time is explored. This will be done by presenting evidence from two central Anatolian Neolithic sites: Aşıklı Höyük and Çatalhöyük. In particular, we argue that households became autonomous and clearly bounded entities only towards the end of the central Anatolian Neolithic, and that too little consideration has been given to the neighbourhood and the local community encompassing individual households.
