Abstract Objective: To test the relationship between positional changes of the proximal segments during surgery and the positional rebound of the mandible during the postsurgical period of orthodontic treatment. Materials and Methods: The sample included records for 34 patients who had received sagittal split surgery for the correction of mandibular prognathism. Data were collected from standardized cephalometric radiographs taken immediately prior to surgery (T2), immediately following surgery (T3), and following the completion of orthodontic treatment (T4). Linear and angular changes in the orientation of the posterior border of the ascending ramus between time points T2, T3, and T4 were measured relative to superimposition on the anterior cranial base. In addition, linear changes in the position of pogonion between T3 and T4 were measured. Results: The magnitude of linear displacement of the posterior border of the proximal segment during surgery (T2 to T3) was statistically significantly correlated (r = .61) with the magnitude of linear displacement of pogonion during the postsurgical phase of orthodontic treatment (T3 to T4). There was a strong relationship between the magnitude of angular (r = .67) displacement of the posterior border of the proximal segments during surgery (T2 to T3) and the magnitude of angular rebound of the posterior border of the proximal segments that occurred during the postsurgical phase of orthodontic treatment (T3 to T4). Conclusions: When rigid fixation procedures alter the position of the proximal segments during sagittal split osteotomy of the mandible, the proximal segments tend to go back toward their presurgical positions following surgery.

SummaryIn a collaborative trial of eleven laboratories which was performed mainly within the framework of the European Community Bureau of Reference (BCR), a second reference material for thromboplastin, rabbit, plain, was calibrated against its predecessor RBT/79. This second reference material (coded CRM 149R) has a mean International Sensitivity Index (ISI) of 1.343 with a standard error of the mean of 0.035. The standard error of the ISI was determined by combination of the standard errors of the ISI of RBT/79 and the slope of the calibration line in this trial.The BCR reference material for thromboplastin, human, plain (coded BCT/099) was also included in this trial for assessment of the long-term stability of the relationship with RBT/79. The results indicated that this relationship has not changed over a period of 8 years. The interlaboratory variation of the slope of the relationship between CRM 149R and RBT/79 was significantly lower than the variation of the slope of the relationship between BCT/099 and RBT/79. In addition to the manual technique, a semi-automatic coagulometer according to Schnitger & Gross was used to determine prothrombin times with CRM 149R. The mean ISI of CRM 149R was not affected by replacement of the manual technique by this particular coagulometer.Two lyophilized plasmas were included in this trial. The mean slope of relationship between RBT/79 and CRM 149R based on the two lyophilized plasmas was the same as the corresponding slope based on fresh plasmas. Tlowever, the mean slope of relationship between RBT/79 and BCT/099 based on the two lyophilized plasmas was 4.9% higher than the mean slope based on fresh plasmas. Thus, the use of these lyophilized plasmas induced a small but significant bias in the slope of relationship between these thromboplastins of different species.

With the deepening of economic globalization, cooperation has become a mainstream trend, revealing the discipline of cooperation has become a key scientific issue. As a content of cooperation, international energy cooperation is a system of relations constituted by different energy cooperation agents, it reflects the composition of agents. Ability divergence and their capability system have an effect on the long-term stability and development of cooperation. Based on the theories, this paper put forward the main connotation of cooperation capacity structure, building capability evaluation system, clearing affect the stability of the key indicators of cooperation, exploring the relationship between cooperation agents’ capability structure and cooperative stability in order to study the whole process of international energy cooperation fluctuations trajectory.

AbstractMaxillomandibular reconstruction requires bone graft, heavy rigid fixation armamentarium and long hospitalization periods. Even with all this the final outcomes are still unpredictable. Patients treated with transport distraction osteogenesis present a better clinical condition, in terms of osteogenesis & histogenesis - identical to adjoining structures. It also has the benefit of producing a good quality and quantity of bone & mucosa, ideal for placement of osseointegrated implants. Thus, bone transport for maxillomandibular reconstruction has now become a gold standard for functional as well as esthetic reconstruction, offering a long term stability.

The Relationship

Both psychedelics and mindfulness are a recently emerging topic of interest in academia and popular culture alike. Personal meditation practices and recreational psychedelic use have consistently increased in the past decade. While clinical work has shown both to improve long-term wellbeing, the data on naturalistic applications of psychedelics and mindfulness is rather lacking. The current study aims to examine the relationship between psychedelic use, mindfulness, and multi-faceted wellbeing as an outcome. Hierarchical regression was used to quantify these associations on a large sample of people (N = 1219), who engage in both meditation practices and psychedelic use. These results show that both mindfulness and mystical experiences each predict substantial increases in wellbeing. Psychedelics were found to be an important moderator of mystical experience to explain improvements in wellbeing. These data are among the first to establish a strong relationship between personal mindfulness practice, recreational psychedelic use, and overall psychological wellbeing in a naturalistic framework.

Building long-term relationships with clients is extremely beneficial for organisations. This does not necessarily imply, however, that the clients themselves need or want a long-term relationship with an organisation. Relationship marketing could profitably be looked at from the client’s perspective, at the same time identifying those clients who have a strong relationship intention and would, in fact, like to engage in a long-term relationship with organisations.The objective of this research was to explore whether three aspects relating to clients, that is, the varying lengths of their relationship with organisations, their age and their gender display significantly different levels of relationship intention. Relationship intention is measured in terms of constructs like involvement, expectations, forgiveness, feedback and fear of relationship loss.Non-probability sampling was used in this study, and 114 respondents from the short-terminsurance industry completed self-administered questionnaires. Findings indicate that, for a group of high relationship-intention clients of a short-term insurance organisation, no practically significant discrimination exists on any of the relationship-intention constructs for clients’ length of relationship, gender or age.

The Relationship

The aim of this paper is to describe the relationships between changes in employee indices (motivation and satisfaction) and customer indices (satisfaction and loyalty) in a single- and multi-term perspective. The article presents the results of primary research conducted in two industries (banking services and shopping centers) during three annual reference periods. The authors used the PLS-SEM method in the analytical process. The results of the research suggest that there is a strong relationship between changes in the areas of employee and customer satisfaction in the studied sectors, with a one-year time shift, which the authors called the “time gap”. In addition, it turned out that the strength of influence of the employee’s motivation level on customers is clearly lower than the strength of influence of the employee satisfaction. The occurrence of a “time gap” between employee and customer processes suggests that any changes introduced in the area of customer service as well as broadly understood human resource management policy need some time to become sustainable—to be noticed by the market and coded in the minds of the recipients of the offer as the new and currently applicable standard. The article makes a successful attempt at a long-term analysis of the relationship between employees and customers, assuming a time delay between both phenomena. As a result of the conducted research, it was possible to operationalize the discussed relationship in terms of strength and direction as well as the time shift.
