Depression and suicidal ideation are common in adolescents. However, the relation between the two is unclear. According to the cognitive model of suicidal behavior and learned helplessness theory, ...lack of certainty in control, referring to individuals’ deficiency in predictability, certainty, and control of life, may be an important factor linking the two. Thus, the current study aimed to investigate the temporal relation between depression and suicidal ideation in adolescents and to assess the mediating role of lack of certainty in control in this relation.
A three-wave survey was carried out at intervals of 1 and 1.5 years among 516 adolescents at several middle schools in Sichuan Province, China. The random-intercept cross-lagged panel model was used to examine the temporal relations between depression, suicidal ideation, and lack of certainty in control among adolescents, which can effectively distinguish between-person and within-person differences.
The results revealed that depression, suicidal ideation, and lack of certainty in control had positive intercorrelations at the between-person level. At the within-person level, early depression predicted subsequent depression and suicidal ideation via lack of certainty in control among adolescents. Additionally, early lack of certainty in control promoted later suicidal ideation through depression.
These findings highlight the mediating role of lack of certainty in control, clarify the temporal relation between depression and suicidal ideation, and provide theoretical support for interventions to address depression and suicide.

Le Manque-à-être, où prend sa source le Désir, se creuse, selon Lacan, dans le moment où nous voulons accéder à un savoir de nous-mêmes. Nous nous perdons à vouloir nous connaître dans et par l’acte ...langagier. En réalité, ce Manque n’est que l’éternelle punition que nous inflige Lacan le religieux, pour notre coupable désir de Savoir. Le Manque incomblable est le châtiment que nous méritons de subir d’avoir voulu prétendre au Savoir. Mais heureusement une cure psychanalytique, lacanienne, pourra nous apporter le salut grâce à un savoir de notre impuissance à savoir. Grâce à elle, nous ne manquerons plus désormais du savoir de notre manque-à-être et de notre impuissance à savoir.

Background/purpose
Pediatric Hodgkin lymphoma (HL) survivors have an increased risk of late effects following treatment. Barriers at the patient, provider, and payor level adversely affect adherence ...to long‐term follow‐up.
Methods
We conducted a retrospective chart review of HL survivors diagnosed from 1999 to 2014 at Texas Children's Hospital. HL survivors were considered lost to follow‐up if there were no documented visits to Texas Children's Cancer Center Long‐Term Survivor (LTS) clinic for 2 or more years after their last LTS clinic visit. Univariate and multivariable logistic regression analyses were conducted to explore factors contributing to loss to follow‐up. Reasons for not attending subsequent LTS visits were assessed by phone interviews in a subset of lost to follow‐up patients.
Results
There were 120 HL survivors who had at least one LTS clinic visit in this timeframe; 64 (53%) were classified as lost to follow‐up, and of these, 23 (36%) were interviewed. Eleven (47%) indicated that the reason for failure to follow‐up was lack of or inadequate insurance, and seven (30%) stated they were unaware of the importance of continued follow‐up. Loss to follow‐up was associated with lack of insurance, earlier diagnosis, and lack of comorbidities in univariate analyses. Only earlier year of diagnosis (odds ratio OR 0.84, 95% confidence interval CI: 0.7–0.9, p = .01) and lack of insurance (OR 22.2, 95% CI: 4–123, p < .001) were associated with loss to follow‐up in multivariable analyses.
Conclusions
Insurance status and awareness of the need for long‐term follow‐up care are key factors associated with loss to follow‐up in survivors of HL. Targeted education and low‐cost options for survivorship care are potential strategies for improving adherence to long‐term follow‐up care in HL survivors.
Successful speech perception requires that listeners map the acoustic signal to linguistic categories. These mappings are not only probabilistic, but change depending on the situation. For example, ...one talker's /p/ might be physically indistinguishable from another talker's /b/ (cf. lack of invariance). We characterize the computational problem posed by such a subjectively nonstationary world and propose that the speech perception system overcomes this challenge by (a) recognizing previously encountered situations, (b) generalizing to other situations based on previous similar experience, and (c) adapting to novel situations. We formalize this proposal in the ideal adapter framework: (a) to (c) can be understood as inference under uncertainty about the appropriate generative model for the current talker, thereby facilitating robust speech perception despite the lack of invariance. We focus on 2 critical aspects of the ideal adapter. First, in situations that clearly deviate from previous experience, listeners need to adapt. We develop a distributional (belief-updating) learning model of incremental adaptation. The model provides a good fit against known and novel phonetic adaptation data, including perceptual recalibration and selective adaptation. Second, robust speech recognition requires that listeners learn to represent the structured component of cross-situation variability in the speech signal. We discuss how these 2 aspects of the ideal adapter provide a unifying explanation for adaptation, talker-specificity, and generalization across talkers and groups of talkers (e.g., accents and dialects). The ideal adapter provides a guiding framework for future investigations into speech perception and adaptation, and more broadly language comprehension.
•Effects of defects, surface roughness and HIP on the fatigue strength of a Ti6Al4V by AM were studied.•HIP improved fatigue strength to the level of ideal fatigue limit if surface roughness is ...removed.•Evaluating method for the effective size √areaeffmax of irregularly shaped defects was proposed.•AM fatigue design method was proposed with the √area parameter model and the statistics of extremes.
The additive manufacturing (AM) is expected to be a promising manufacturing process for high strength or hard steels such as Ti-6Al-4V for the aerospace industry components having complex shapes. However, disadvantage or challenge of AM is presence of defects which are inevitably contained in the manufacturing process. This paper focuses on the effects of defects, surface roughness and Hot Isostatic Pressing (HIP) process on the fatigue strength of a Ti-6Al-4V manufactured by AM. Defects were mostly gas pores and those made by lack of fusion. Many defects which were formed at subsurface were eliminated by HIP and eventually HIP improved fatigue strength drastically to the level of the ideal fatigue limit to be expected from the hardness. Surface roughness had strong detrimental influence on fatigue strength. The method for estimating the effective size √areaeffmax of irregularly shaped defects and interacting adjacent defects was proposed from the viewpoint of fracture mechanics.
This review provides an overview of air-drying binders and chemical processes responsible for their solidification and hardening. It is focused not only on binders derived from plant oils but also on ...oriental lacquers and their synthetic congeners as their curing is also based on chemical reactions with air-oxygen. The main aim of this review is to bring a critical view on the mechanism of the autoxidation process relevant to paint technology and highlight the previous misinterpretation, remaining open questions, and gaps in the current state of knowledge. Such an objective was achieved by utilization of the latest knowledge appearing in various areas of the chemical research, e.g., organic chemistry, biochemistry, physical chemistry, computational chemistry, and inorganic chemistry. Considerable attention is also given to recent developments in the field of transition metal driers and additives including clarification the role of cobalt-based driers and an updated overview of cobalt replacement.
