Testo completoAbstract (sommario):
Known as a Taoist, Yang Zhuw lived in the Warring States Period. In his only transmitted work named ‘Yangzhu’in Liezi, he presented the “tending life” theory which was considered by most scholars as a sort of “hedonism,” “extreme egoism” or “indulgence.” However, the “tending life” theory should not be simply regarded as an avocation of physical enjoyment. First, ‘Yangzhu’ defined Tao（the Way） as a “weak power” which only assists things to “auto-generate” and “self-transform,” so that “tending life” is also a pursuit of the ultimate meaning of Tao. ‘Yangzhu’ further argued that the best way of “tending life” is not to restraint and suppress one’s natural desire, for the realization of “tending life” should be based on the preservation of the body. ‘Yangzhu’ discusses the relationship between the “Ming”(name/reputation) and the “Shi”(Reality), which reveal that the attachment to the “reputation” is the main obstacle of the realization of “tending life.” At last, Yang Zhu proposed that the most ideal life should “roaming as the nature prompt” through a dialectical discussion. Therefore, the theory of “tending life” also reflects a pursuit that to some extent transcends the physical life.

Is young growth tending successful in the Swiss Plateau region? Analysis and implications (essay) The effect of the cost-intensive young growth tending used up to the present in the region of the Swiss Plateau is analysed using different approaches. It is evident that young growth tending is not only ineffective with respect to diameter growth but even hinders stand development. Negative effects on quality from young growth tending are also recognised. This is often due to premature interventions in the natural processes of self-differentiation and subsequent systematic errors in the thinning. Furthermore, the effect of tending measures on the tree species composition is often overestimated because in the first 10 to 20 years of stand development, it is primarily the rejuvenation strategy and the site which are decisive. As an alternative course of action, tending concepts are proposed which rely on biological rationalisation and future tree thinning, to achieve future trees which are as vigorous as possible. These are not only more effective, but are also significantly less expensive.

Testo completoAbstract (sommario):
The problem of extrapolating asymptotic perturbation-theory expansions in powers of a small variable to large values of the variable tending to infinity is investigated. The analysis is based on self-similar approximation theory. Several types of self-similar approximants are considered and their use in different problems of applied mathematics is illustrated. Self-similar approximants are shown to constitute a powerful tool for extrapolating asymptotic expansions of different natures.

Testo completoAbstract (sommario):
Stem, branch, needle, and total aboveground biomass were assessed for three 9- to 12-year-old white spruce (Picea glauca (Moench) Voss) plantations, each subjected to three different stand tending options at age 4 to 7. Biomass components were predicted from measures of stem diameter with coefficients of variation between 24% and 29%. Diameter at breast height (DBH) generally provided lower prediction precision than did the lower stem measures tested (coefficient of variation > 35%). The addition of tree height in models reduced the standard error of the estimates for stem and total biomass by an average of 48% and 8%, respectively, and compensated for different height/diameter ratios imposed on the spruce by the stand tending treatments. Needle and branch biomass models were invariant to the tending treatments and, consequently, to the addition of height as an independent variable. Predictions from existing published white spruce equations suggest that extrapolation to this study area would have led to adequate stem biomass estimation but to serious (>55%) underestimates of branch, needle, and, correspondingly, total biomass. Slow self-pruning by plantation spruce, particularly before crown closure, is cited as a possible reason for these differences.

Testo completoAbstract (sommario):
Abstract Objectives were to investigate effects of supplement feeding time and delivery method on performance and grazing behavior of backgrounded steers. Crossbred steers (n = 109; 7 ± 1 m of age; BW = 245 ± 2.9 kg) were stratified by BW and source into 18 groups (6–7 steers per group), and randomly allotted to tall fescue pastures during 38- and 45-d treatment periods during fall of 2019 and 2020, respectively. Pasture groups were randomly assigned to 1 of 3 treatments (6 pastures per treatment): 1) steers hand-fed a commodity blend supplement at 0930 h (AM), 2) steers hand-fed supplement at 1330 h (PM), or 3) steers fed a commercially available self-fed supplement with an intake limiter (SELF). All treatments were formulated for as fed supplement intake of 1.5% BW. Pedometers were used to estimate animal activity level. Motion-sensing cameras were used in yr 1 to monitor feeder and waterer visits. Data were analyzed using the MIXED procedure in SAS with main effects of year, group, and treatment with pasture as a random effect. Treatment had no effect (P ≥ 0.13) on calf BW, flesh condition score, ADG, or ultrasound 12th rib fat thickness. Supplement DMI tended (P = 0.08) to be greater for SELF relative to hand-fed cattle, with yr 2 tending (P = 0.07) to be greater than yr 1. There was a treatment x year interaction (P = 0.04) for G:F with SELF and AM steers in yr 1 tending (P ≤ 0.09) to be greater than SELF in yr 2, with all other treatments being intermediate and not different. Self-fed cattle had greater (P ≤ 0.01) activity level and more (P = 0.01) visits to feeders relative to hand-fed treatments. Results indicate that performance of backgrounding steers was not greatly impacted by supplementation schedule or delivery method.

Testo completoAbstract (sommario):
Self-similar approximation theory is shown to be a powerful tool for describing phase transitions in quantum field theory. Self-similar approximants present the extrapolation of asymptotic series in powers of small variables to the arbitrary values of the latter, including the variables tending to infinity. The approach is illustrated by considering three problems: (i) The influence of the coupling parameter strength on the critical temperature of the O(N)-symmetric multicomponent field theory. (ii) The calculation of critical exponents for the phase transition in the O(N)-symmetric field theory. (iii) The evaluation of deconfinement temperature in quantum chromodynamics. The results are in good agreement with the available numerical calculations, such as Monte Carlo simulations, Padé-Borel summation, and lattice data.

Testo completoAbstract (sommario):
Cytotoxic T cells recognize cell surface complexes of MHC class I proteins with peptides derived from proteins synthesized within the recognized cell. A mechanism permitting some intracellular discrimination between self proteins and not-self proteins (encoded by a foreign species) would allow the preferential loading of MHC proteins with peptides derived from not-self proteins. This would decrease competition with peptides derived from self proteins and decrease gaps in the T cell repertoire. A possible mechanism has been derived from studies of the specificity of self-aggregation of erythrocytes and of virus coat protein. It is postulated that genes whose products occupy a common cytosol have co-evolved such that product concentrations are fine-tuned to a maximum consistent with avoiding self-aggregation. Cytosolic proteins collectively generate a pressure tending to drive protein molecules into self-aggregates. Each individual protein species both contributes to, and is influenced by, this pressure. The aggregation involves a liberation of bound water and an increase in entropy. The concentrations of proteins encoded by viral genes (not-self) readily exceed the solubility limits imposed by the crowded host cytosol. This leads to their preferential degradation to peptides which associate with MHC proteins. The intracellular and extracellular self/not-self discrimination systems complement each other to ensure that there is no immunological reaction against normal self tissue components.

We examined the moderating effects of self-esteem and gender on the relationship between extraversion and subjective well-being in Chinese university students. Participants were 542 students (217 men, 325 women; age range = 17–24 years), who completed the Rosenberg Self-Esteem Scale, the extraversion subscale of the NEO-Five Factor Inventory, and the General Well-Being Schedule to evaluate self-esteem, extraversion, and subjective well-being, respectively. Hierarchical regression analysis showed that self-esteem moderated the association between extraversion and subjective well-being. Among students high in self-esteem, those with high extraversion had higher subjective well-being than did those with low extraversion. Across all participants (high- and low-extraversion groups), subjective well-being was low when self-esteem was low. Gender moderated the link between extraversion and subjective well-being, tending to be a more significant determinant of subjective well-being in men than in women.

Visual navigation is an important technology for Autonomous Guided Vehicles and road detection is the essential prerequisite. It is a challenging problem to distinguish the road or its boundaries in unstructured environments for the lack of discernible features. A self-supervised road detection method is proposed in this paper. Vanishing point is first detected using only four Gabor filters to precisely estimate the local dominant orientation at each pixel location, and an adaptive soft voting scheme is used to prevent tending to favor points that are high in the image. Training area is defined with vanishing point, which color feature is used for building self-supervised learning models to describe the road segment. Road patches are selected by measuring the roadness score. Experimental results have shown the efficiency of the method in terms of detection result and time saving.

The article deals with the history, traditions and way of life of sub-ethnic group of the Finno-Ugric tribes –the Eastern Maris, who are considered the "last pagans of Europe". Using specific ethnographic material, scientific and popular-scientific works, the authors showed the unique culture of the Eastern Maris sub-ethnos, pagan beliefs, preserved to date and reflecting people’s social existence, beauty of the traditions and essential national characteristics. The authors draw a conclusion that the Eastern Maris present an independent sub-ethnos tending to self-reproduction. Being amidst the powerful Slavic and Turkic civilizations, the Eastern Marian sub ethnos managed to maintain its national self-identity with some borrowings from neighboring cultures.

Abstract Based on the energy flow theory of nonlinear dynamical system, the stabilities, bifurcations, possible periodical/chaotic motions of nonlinear water-lubricated bearing-shaft coupled systems are investigated in this paper. It is revealed that the energy flow characteristics around the equlibrium point of system behaving in the three types with different friction-paramters. (a) Energy flow matrix has two negative and one positive energy flow factors, constructing an attractive local zero-energy flow surface, in which free vibrations by initial disturbances show damped modulated oscillations with the system tending its equlibrium state, while forced vibrations by external forces show stable oscillations. (b) Energy flow matrix has one negative and two positive energy flow factors, spaning a divergence local zero-energy flow surface, so that the both free and forced vibrations are divergence oscillations with the system being unstable. (c) Energy flow matrix has a zero-energy flow factor and two opposite factors, which constructes a local zero-energy flow surface dividing the local phase space into stable, unstable and central subspace, and the simulation shows friction self-induced unstable vibrations for both free and forced cases. For a set of friction parameters, the system behaves a periodical oscillation, where the bearing motion tends zero and the shaft motion reaches a stable limit circle in phase space with the instant energy flow tending a constant and the time averaged one tending zero. Numerical simulations have not found any possible chaotic motions of the system. It is discovered that the damping matrices of cases (a), (b) and (c) respectively have positive, negative and zero diagonal elements, resulting in the different dynamic behavour of system, which gives a giderline to design the water-lubricated bearing unit with expected performance by adjusting the friction parameters for applications.

AbstractObjectiveTo investigate the accuracy of self-reported weight status over the adult lifespan.DesignEstimates of self-report bias were obtained from a linear regression analysis and the magnitude of the discrepancy was studied for demographic groups (based on gender, race and educational attainment), weight status, number of years from the age of the reported weight and current age of the respondent.SubjectsA subset of 6101 individuals from the National Health and Nutrition Examination Epidemiological Follow-Up constituted the study sample.ResultsGender, elapsed time and BMI contributed to self-report bias. Effects of gender and elapsed time were small relative to the effects of BMI, with women tending to underestimate weight by 0·82 kg (1·8 lb), men overestimating by 2·27 kg (5·0 lb) and bias increasing by 0·09 kg (0·2 lb) for each year of retrospection. Every increase of one unit in BMI was associated with an additional 0·91 kg (2·0 lb) underestimate in self-reported weight.ConclusionAccuracy of adult self-reported weight profiles will be greatly underestimated if samples have individuals of current or past high relative weight. Adjusting for underestimation based on the respondent’s weight status alone will considerably improve the validity of weight information.

The active screen ion sulphurized layer was prepared on the surface of CrMoCu alloy cast iron by using active screen ion sulphurizing technology. Its key composition is FeS. Under epinoc grease lubrication condition, the friction factor and the wear volume of the active screen ion sulphurized layer is 24% and 40% lower than that of the plain surface and close to that of the sulphurized layer, respectively. The active screen ion sulphurized layer has excellent self-lubrication property, and its loose and porous structure tending to store the grease, which make it possess excellent friction reduction and wear resistance performances.

Testo completoAbstract (sommario):
Cognitive predictors, such as relatively accepting attitudes toward forcible date rape, helped identify self-reported sexually coercive college students and were expected to help identify students voting not guilty in a simulated acquaintance rape trial. To test this hypothesis college students self-administered in random order (1) an anonymous sex survey measuring attitudes toward forcible date rape, attitudes toward women, sexual experience, including victimization, sexual permissiveness, and sexual knowledge and (2) a trial survey based on a simulated acquaintance rape trial. Only gender and cognitive variables from the trial (e.g., being male, tending to blame the victim, and uncertainty about one's verdict) identified not guilty verdicts above chance expectancy. Thus, the hypothesis that the cognitive predictors measured here would help identify students voting not guilty in a simulated acquaintance rape trial was not supported.

Testo completoAbstract (sommario):
This article analyzes recent developments in the village self-government movement (democratic elections, democratic decision making, democratic management, and democratic supervision) in Guangdong in 2002 as a lens through which to view the village self-government movement throughout China. In reviewing changes in both election practices and the anticorruption components of such elections, the article concludes that the new discourse and mechanisms of village self-government, including nomination, voting, and recall procedures, include significant, although gradual and sometimes contradictory, progress towards participatory elections and, to a lesser extent, popular democracy while tending to empower new groups in local politics with the potential to challenge elements of the existing power structure. In addition, the anticorruption elements of this movement, particularly new transparency and accounting practices, incorporate numerous elements of both the Chinese leadership and internal anticorruption experts' prescriptions for combating corruption, although other factors in these processes may limit their effectiveness. However, any meaningful evaluation of the success of this movement can only occur in the context of recognition of the significant changes in both China's domestic social formation and increasing globalization, neoliberalism, and corporatization worldwide, both of which have significant effects on the village self-government movement.

Testo completoAbstract (sommario):
Implicit in most recent social science explanations of human behavior is a conception of man as universal homo economicus. Although such a conception is capable of giving a powerful account of a great deal of human action, its account of the nature and variety of human values is inadequate. Cultural assumptions about the meaning of “self” and “others,” and about relations between human beings, are likely to vary from one society to another. These assumptions affect the collective decision processes of political elites under conditions of complexity, uncertainty, and ambiguity. The author first addresses the question of how to construct a compelling cultural explanation, and then offers evidence which suggests that, because Chinese, Japanese, and Russians tend to hold somewhat different conceptions of “self” and “others” than do Americans (the former tending to be more collectivist than the latter), these different conceptions have implications for collective decision making.

Testo completoAbstract (sommario):
Abstract Recent philosophical and theological writing on Augustine in France, England and North America is sharply divided between readings which serve either a historicist, anti-metaphysical, postmodern retrieval or an ahistorical, metaphysical, modern reassertion. The postmodern retrieval begins from a Heideggerian «end of metaphysics» and goes at least some distance with Jacques Derrida's development of its consequences. This essay starts from engagements with Augustine by Derrida and Jean-Luc Marion, moving then to Rowan Williams on the De trinitate, read to prevent comparison with Descartes' Meditations, and considers how Williams relates Augustine to Plotinus. The opposed modernist interpretation appears in Stephen Menn's Descartes and Augustine, which sees a continuity between Plotinus, Augustine and Descartes. Finally, the essay treats Plotinus and Augustine on God and self-knowledge, maintaining that Augustine's De trinitate is better understood from within a modern ahistorical stance which, within metaphysics, places Augustine together with Plotinus and Descartes. This view better captures his difference from Plotinus than the alternative postmodern perspective tending to assimilate Augustine to Plotinus.

The purpose of this study to identified the relationship between self compassion and stress of schizophrenis family caregiver in Puskesmas (PHC) Mumbulsari Jember. The study used correlation study with the cross sectional approach. The sampling was counted 35 family caregiver using total sampling. The instrument used self compassion scale (α=0,89) and stres in family (α=0,977). The result showed that the average self compassion of family caregiver was 71.31(26-104). While the average stress of family caregiver was 18,74 (0-28). Bivariate analysis using pearson test showed that there was no correlation between self compassion and stress of schizophenia family caregiver in Puskesmas (PHC) Mumbulsari Jember. There was no correlation between stress of schizophenia family caregiver and gender, age, education level, profession, relationship with schizophenia patient, and long tending of family caregiver. This has showed that family caregiver covered stress and showed a positive self acceptance. Actually, family caregiver showed that noncompliance of patient recovery, many of them was not accompanying schizophenia patient to public health, and neglecting schizophenia patient. Counseling and health promotion should be enhanced psychological health of family caregiver in treating schizophrenia patient in community through public health care serving.

This study assessed the links between maternal sleep and mothers’ perceptions of their attachment relationship with their infant among women at risk for postpartum depression by virtue of having been depressed during pregnancy. Sixty-two mothers completed sleep diaries and questionnaires at 3 and 6 months postpartum. Regression analyses, controlling for depression severity and infant temperament, revealed significant prospective correlation between maternal shorter total sleep time at 3 months and lower scores on a mother–infant attachment questionnaire at 6 months. At 6 months, the longer time mothers were awake tending to their infants the lower were their attachment scores. The findings suggest that improving sleep of mothers who suffered from prenatal depression may have a positive effect on mothers’ self-reported relationship with their infants.

Testo completoAbstract (sommario):
A decaying 2D homogeneous and isotropic turbulent flow is considered in the self-similar limit, which is achieved with large values of the Reynolds number formed using the time and kinetic energy of the flow if the initial value of the averaged enstrophy tends to infinity with the viscosity tending to zero. In this case, the enstrophy-dissipation rate has a nonzero finite limit. The correlation function of the vorticity field and the enstrophy spectral density in the inertial range of distances and wave numbers, where these functions are free from the effect of viscosity and large-scale flow parameters, is investigated. It turns out that the inertial range exists in the decaying 2D self-similar turbulence in physical space but is absent in the space of wavenumbers. This means that the turbulent vortices of the appropriate size do not contribute to the spectral density, and the well-known law of the first degree is not satisfied. At large wave numbers, the spectral density of enstrophy behaves nonmonotonically - it first decreases faster than the law of the minus first degree and, then, in the dissipation region, it has a growth segment and a second peak. In this case, the enstrophy flow along the spectrum on the left boundary of the dissipation region is only a fraction of the enstrophy-dissipation rate.

Two-dimensional profilometry is an inexpensive well-established technique to identify indicators of tooth wear. Four surface parameters ( Ra, Rq, Rsk, and Rku) were selected in this work to evaluate worn dental surfaces using two-dimensional profilometry. Eight subjects with dental wear were molded four times with a 15 days interval. To verify data correlation, a mixed-effects model was adjusted. The results indicated that Ra, Rq, Rsk are time dependent, while Rku remained constant. Rsk and Rku values were useful to identify surfaces. Skewness had oscillatory variations and Rku was tending toward a constant rate for a longer period. Two regimens were suggested: (1) transient and (2) self-limiting. Final variation rates indicated that, although enamel wear transiently modifies the surface, it maintains its isotropic characteristic: symmetrical and approximately normal asperities distribution.

Caring science is an extant theory of human relationship, guiding the profession of nursing with the understanding and application of a moral-ethical praxis that promotes, protects, and provides human dignity throughout the life continuum. Over the past 30 or more years, caring science has transformed nursing by calling for a heightened ethical perspective of human dignity in how nurses practice, educate, research, and evolve the profession. Conscious dying is a framework rooted in a human caring ontology, which strives to deepen the nurse healer’s awareness in tending to a patient’s dying and death, returning death to its sacred place in the cycle of life. Reflective inventories are self-reflection tools that have been used to encourage nurses’ personal growth and development and may be utilized in individual or group settings. The purpose herein is to introduce an emerging metaparadigm that links self to system, interweaving and integrating the teachings of caring science and conscious dying through the use of reflective inventories for both the individual nurse and collective of nursing.

Diabetes mellitus and its complications carry broad financial misfortune to the diabetic patients and their family, to the well-being frameworks, and to the public economies through direct clinical expenses and decreased work efficiency. The present study systematically reviewed the possible factors that are influencing self-care behavior of disadvantaged diabetic patients that contribute heavily to the management of this chronic illness. Structured searches were conducted on PubMed, ScienceDirect, and manual searches on Google Scholar for articles published between the years 2000 and 2020. The review was limited to a particular time frame due to the change in WHO criteria for diagnosis and classification of abnormal glucose tolerance. Initially, 96858 articles were identified, and following the screening and full-text reading, 10 studies that met the inclusion criteria were chosen for systematic review. Seven studies had reported the factors influencing self-care behavior among disadvantaged diabetic population. Three studies had reported the importance of intervention strategies and its impact on self-care behavior among them. Findings show that self-care management of socio-economically disadvantaged people entails dimensions including diabetes knowledge, lack of physical activities, social support, lack of access to services, life disruptions, denial of illness, societal attitudes, responsibilities, and treatment costs. It was additionally discovered that diabetes self-management support mediations are successful in drawing in lower economy patients, tending to contending life needs and hindrances to self-care, and encouraging behavior change. Taken together, future methodologically efficacious studies that establish health promoting behaviors and explorations of the factors influencing self-care behaviors of disadvantaged diabetic patients are needed.

AbstractThe aim of this study was to compare and get a deeper insight into issues of the health and health behavior inequalities among Lithuanian, Polish and Russian school-aged children in national and international contexts. Investigations were carried out in the framework of Health Behavior in School-aged Children (HBSC) study — a WHO collaborative cross-national survey. Five thousand seven hundred and seventy six randomly selected students aged 11, 13, and 15 years of age answered questionnaires in the classroom in 108 schools located in different regions in Lithuania in March–April of 2006. Questions on perceived health and health related behaviors were addressed to the respondent (response rate was 95 %). 5632 questionnaires were selected for further analysis by the international data center in Bergen. SPSS version 11.5 and multilevel analysis program MLwiN 2.0 was applied for statistical analysis of data. Relatively minor inequalities in health and health behavior were established when comparing different health and health behavior indicators in Lithuanian, Polish and Russian school-aged children in Lithuania. These disparities are lower in comparison with differences, which were established among respondents of HBSC international studies. Odds ratios to have negative self-rated health evaluation were higher in girls of Russian (OR-1.71, p<0.05) and Polish (OR-1.62, p<0.05) nationality. Therefore, Russian and Polish students were tending to have higher odds ratios for perception of happiness (p<0.05). Respondents of Russian nationality have expressed less somatic and psychological complaints. Polish boys (OR=1.38, p<0.05) were tending for higher prevalence of headache, but have expressed fewer complaints for depression (OR=0.65, p<0.05), anxiety (OR=0.71, p<0.05). Chances to be involved in risk taking behaviors (alcohol consumption, smoking, drug use) were lower among Polish and Russian respondents. In schools with Lithuanian language based-schoold, health and health behavior indicators were more negative in Polish and Russian respondents in comparisons with their Lithuanian peers However, Lithuanian students, who were enrolled in Russian and Polish schools, tending to have better perceived health evaluation and better health behavior in comparison with their peers of Polish and Russian nationality. Analysis shows, that Polish and Russian students are integrated well into Lithuanian society and being a member of the minority class is not related to poor health or negative lifestyle. Therefore, with few exceptions universal health promotion programs should be provided to school-aged children of all ethnicities and cultural backgrounds.

Historians have long been aware that the vicious feud between the monastery of Glastonbury and its bishop in the early thirteenth century was responsible for turning Glastonbury’s scriptorium into the most astonishing and inventive manufacturer of forged documents. In what Julia Crick has memorably termed ‘the marshalling of antiquity’, new documents were produced and older ones annotated, all tending to demonstrate the antiquity of Christian Glastonbury, and its right to self-government and autonomy, free from external interference. The monastery’s chroniclers were equally partisan, but historians and archaeologists alike have tended to accept their account of Glastonbury’s more recent history at face value. Correcting the chroniclers’ anti-Savaric bias allows for some fresh thinking on the construction of both the Glastonbury mythos and of the abbey building itself. It also raises questions about the remarkable reverence with which scholars continue to treat Glastonbury’s ancient texts.

Subjects (39 men and 30 women) from two university counseling centers and one university medical center were administered the Hamilton Rating Scale for Depression, the Buss-Durkee Hostility Inventory, the State-Trait Anger Scale, and the Hostility and Direction of Hostility Questionnaire. Results showed significant positive correlations between self-reported severity of depression and all subtypes of hostility including behavior, attitude, affect, intropunitiveness, and extrapunitiveness. Hierarchical regression analysis using demographic and hostility variables as predictors of depression scores showed increasing age, lower education, and female gender to account for 50% of the explained variance. The Intropunitive subscale from the Hostility and Direction of Hostility Questionnaire accounted for an additional 19% of the explained variance and was the single most powerful predictor of depression. Correlational analysis showed women tending to have higher scores on most hostility measures. Implications of these results with respect to theory and clinical practice are discussed.

Documentation used in psychotherapy for quality assurance can be useful, but also time consuming and inflexible. In the process of behavior analysis, therapy planning and conducting therapy, a large amount of clinical data have to be structured and organized. We present an economical documentation method that contains information about the most important causes of problem behavior and expectations about how much certain therapy components will achieve the therapist and client therapy aims. This documentation method can assist therapy planning, serve as a communicative tool for colleagues and supervisors, serve as an educational tool for clients, and be utilized as a self-reflective therapy discourse (quality assurance). The paper describes and pilots the use of a transtheoretical, graphic approach, the therapeutic concept diagram, for the above-mentioned aspects of quality assurance. Four experienced analytic therapists and six experienced cognitive-behavioral therapists documented therapeutic concept diagrams for five clients each. These 50 recorded therapeutic concept diagrams are described. In general, the diagrams were rated as useful for documentation and treatment planning. Ratings of the diagrams as a communicative tool and for a self-reflective therapy discourse were heterogenic, with analytical therapists tending to benefit more. The discussion focuses on application settings and limitations and highlights the heuristic value of assessing idiographic hypotheses.

Testo completoAbstract (sommario):
IntroductionObservational and intervention studies have verified that weight loss predicts a reduced type 2 diabetes (T2D) risk. At the population level, knowledge on the prediction of self-report intentional weight loss (IWL) on T2D incidence is, however, sparse. We studied the prediction of self-report IWL on T2D incidence during a 15-year follow-up in a general adult population.Research design and methodsThe study sample from the representative Finnish Health 2000 Survey comprised 4270 individuals, aged 30–69 years. IWL was determined with questions concerning dieting attempts and weight loss during the year prior to baseline. Incident T2D cases during a 15-year follow-up were drawn from national health registers. The strength of the association between IWL and T2D incidence was estimated with the Cox model.ResultsDuring the follow-up, 417 incident cases of T2D occurred. IWL predicted an increased risk of T2D incidence (HR 1.44; 95% CI 1.11 to 1.87, p=0.008) in a multivariable model. In interaction analyses comparing individuals with and without IWL, a suggestively elevated risk emerged in men, the younger age group, among less-educated people and in individuals with unfavorable values in several lifestyle factors.ConclusionsSelf-report IWL may predict an increased risk of T2D in long-term, probably due to self-implemented IWL tending to fail. The initial prevention of weight gain and support for weight maintenance after weight loss deserve greater emphasis in order to prevent T2D.

ENGLISH law sets out from the proposition that, lest it prejudice the tribunal, the prosecution in a criminal case may not adduce evidence that an accused has committed any wrongdoing other than the offence(s) actually charged. Although other misconduct evidence is still supposed only to be admitted if strongly relevant to the issues being tried, over the years the courts have steadily relaxed this self-denying ordinance. Most recently, in D.P.P. v. P [1992] 2 A.C. 447 Lord Mackay L.C. abandoned the view espoused by members of the House of Lords in D.P.P. v. Boardman [1975] A.C. 421 that other misconduct evidence may only be adduced if it displays a “striking similarity” to the misconduct charged. He declared that in determining its admissibility a judge had only to consider whether the probative force of the other misconduct was “sufficiently great to make it just to admit the evidence, notwithstanding that it is prejudicial to the accused in tending to show that he was guilty of another crime” (p. 460).

BackgroundIn the face of rapidly expanding empirical knowledge about this common childhood condition, there is a need for an up-to-date synthesis, especially for the use of practising clinicians.MethodThe main epidemiological, experimental and clinical studies over the past decade are selectively reviewed.ResultsHyperkinetic/attention deficit hyperactivity disorder is common, with young school-age males most frequently affected. The prevalence figures vary depending on the criteria used. Overlap with conduct disorder is high. The causes are likely to stem from a combination of biological, often genetically determined neurochemical disturbances, and environmental disadvantages, with the biological risk tending to be highest in severely hyperactive girls. Good clinical management combines pharmacological, psychological and educational approaches in a sustained manner. Even then, the outcome is often equivocal and the long-term psychosocial adaptation unpredictable.ConclusionsClinically significant hyperactivity is rooted in biological, often genetically transmitted vulnerabilities, upon which environmental disadvantages transact. It may be viewed as a disorder of self-regulation with its roots partly in strained early caregiver–child interactions and disrupted primary attachments.

A review of the literature on experiences and meanings surrounding suicide ideation in LGBT youth was conducted. It was found that a large part of the studies were carried out in Anglo-Saxon populations that tended to compare "heteronormative" with "non-heteronormative" populations, through eminently quantitative designs, where the main results were greater vulnerability in comparison to the heterosexual population, internalized homophobia and rejection of one's own sexual orientation. Social and family vulnerability that fed the experience of diverse violence in different areas of their lives. In addition, alcohol and drugs were predictors of suicidal ideation. These living conditions favored mood disturbances and affected mental health, as well as a tendency to develop self-injurious behaviors. However, family and social support were protective against suicidal ideation. Few authors used the recognized categories within the LGBT community to describe their participants, the category most commonly used was "non-heteronormative population", tending to reproduce heterosexist models. Most of the papers on experiences and meanings did not give their participants a voice.

BackgroundAs the number of patients surviving traumatic injuries has grown, understanding the factors that shape the recovery process has become increasingly important. However, the psychosocial factors affecting recovery from trauma have received limited attention. We conducted an exploratory qualitative study to better understand how patients view recovery after traumatic injury.MethodsThis qualitative, descriptive study was conducted at a Level One university trauma center. Participants 1–3 years postinjury were purposefully sampled to include common blunt-force mechanisms of injuries and a range of ages, socioeconomic backgrounds and injury severities. Semi-structured interviews explored participants’ perceptions of self and the recovery process after traumatic injury. Interviews were transcribed verbatim; the data were inductively coded and thematically analyzed.ResultsWe conducted 15 interviews, 13 of which were with male participants (87%); average hospital length of stay was 8.9 days and mean injury severity score was 18.3. An essential aspect of the patient experience centered around the recovery of both the body and the ‘self’, a composite of one’s roles, values, identities and beliefs. The process of regaining a sound sense of self was essential to achieving favorable subjective outcomes. Participants expressed varying levels of engagement in their recovery process, with those on the high end of the engagement spectrum tending to speak more positively about their outcomes. Participants described their own subjective interpretations of their recovery as most important, which was primarily influenced by their engagement in the recovery process and ability to recover their sense of self.DiscussionPatients who are able to maintain or regain a cohesive sense of self after injury and who are highly engaged in the recovery process have more positive assessments of their outcomes. Our findings offer a novel framework for healthcare providers and researchers to use as they approach the issue of recovery after injury with patients.Level of evidenceIII—descriptive, exploratory study.

Exposing hubris syndrome, a behavior pattern that is not in accordance with the norms of standard behavior and becomes part of a mental disorder is the objective of the study. This syndrome usually occurs in someone with power in hand, tending to be tyrannical and feeling to be always right. In the study of literature Hubris syndrome refers to the tragic flaw that brings a person, usually an important figure, to a self-destruction. Hubris syndrome can occur to anyone. The method used is descriptive qualitative tied to things experienced by the community termed a social phenomenon. The results show that the central figure in this novel, a captain of a whale hunting vessel, experiences hubris syndrome with three prominent patterns of behavior: narcissistic propensity, excessive confidence and loneliness. In the first pattern, the person concerned feels like a superhuman deserving to be admired and attended to. The second, excessive self-confidence cannot be accepted by rational thinking. The third is the consequence of the first two patterns of living a life of solitude because of losing contact with the surroundings. The storyline ends tragically; the entire crew is killed by the whale and only one left and becomes a narrator. Hubris syndrome in the novel is a reality meaning that anyone who has a certain position tends to have Hubris syndrome and this is in line with the findings in the field with a percentage reaching 92.

AbstractBritish reactions to China's increasing engagement with Africa in recent years have been manifested in particularly negative and reductive ways tending to depict China's presence in Africa as destructive and self-serving, in contrast to Britain's more enlightened, supportive approach. However, more recently official discourse has begun to stress the shared outlook between British and Chinese objectives, emphasising Chinese moves towards a more constructive, development-focused approach in Africa. This article discusses the ways in which China in Africa is viewed in British political circles and assesses the degree to which such views resonate with the British sense of its own idealised identity. It suggests that the two narratives represent two sides of a dual ‘liberal’ approach to the problem of ‘non-liberal’ actors in international politics: first the tendency to reject and see them as outside the international order; and second the attempt to rehabilitate them and bring them within it. The article concludes by exploring a number of reasons for the particular ways in which Britain, China and Africa are configured, arguing that this dual conception represents a sense of ambiguity about the potential universality of liberalism.

Testo completoAbstract (sommario):
Current studies regarding the permeable properties, corrosion properties, and seepage characteristics of cemented sand and gravel (CSG) materials are based on laboratory tests. Thus, there is a lack of studies analyzing the permeable character of seepage fields based on monitoring data from real prototypes working under practical operating conditions. In this paper, on the basis of measured data from the Dahuaqiao cofferdam, we establish an inversion analysis method for unsteady seepage fields covering different time periods within a time sequence. The results indicate an effective dynamic change law for the material permeability coefficient and the real dynamic evolution characteristics of seepage fields. The permeability coefficient of CSG exhibits a “self-healing” phenomenon similar to concrete, with the seepage characteristics of a dam tending to become stable over time. Under the long-term action of water pressure, the seepage behavior of the dam body shows no obvious deterioration, suggesting that CSG can satisfy the required anticorrosion property expected of dam construction materials. Thus, abnormal CSG might serve as an effective antiseepage layer that can meet the running requirements of cofferdams. The results of this research can provide reference for further improvement in the CSG dam design theory.

ABSTRACT Using hydrodynamical simulations of a Milky Way-like galaxy, reaching 4.6 pc resolution, we study how the choice of star formation criteria impacts both galactic and giant molecular cloud (GMC) scales. We find that using a turbulent, self-gravitating star formation criteria leads to an increase in the fraction of gas with densities between 10 and $10^{4}{\, \rm {cm^{-3}}}$ when compared with a simulation using a molecular star formation method, despite both having nearly identical gaseous and stellar morphologies. Furthermore, we find that the site of star formation is effected with the the former tending to only produce stars in regions of very high density (${\gt}10^{4}{\, \rm {cm^{-3}}}$) gas, while the latter forms stars along the entire length of its spiral arms. The properties of GMCs are impacted by the choice of star formation criteria with the former method producing larger clouds. Despite the differences, we find that the relationships between clouds properties, such as the Larson relations, remain unaffected. Finally, the scatter in the measured star formation efficiency per free-fall time of GMCs remains present with both methods and is thus set by other factors.

There is a felt need to understand the way ethnic identities are constructed by Afrodescendant boys and girls aged 6-12 in school contextsin Bogotá as there is little research in such specific context and topic in Colombia. This research report proposes a discourse analysis andsocial psychology approach to tackle such problem. Thus this paper seeks to identify the discursive mechanisms that allow us to know howidentity processes emerge from the acceptance or denial of ethnicity; mechanisms that may lead or have an effect on discursive adaptation,resistance or negotiation. Findings suggest that children begin early their ethnic self-identification from the color of the skin, whereby theydifferentiate a wide color range, tending towards whitening. Children have different degrees of ethnic appraisal that go from pride to rejection.In inter-ethnic relations, they tend to deny or minimize the conflict, and there is a tendency to avoid speaking about it. Children identify thecause of the problem as a quantitative issue, as they are minority in Bogotá. In inter-ethnic dynamics, some children accept the stereotypesassigned to them, others reject them, and others scoff at them.

Testo completoAbstract (sommario):
The critical role of divalent ions (M²+) in the self-assembly of SbpA S-layer proteins (from Lysinibacillus sphaericus CCM 2177) into crystalline structures has been reported in several studies. Hence, ions such as magnesium, barium, nickel and, most commonly, calcium (Ca²+) have proven to trigger both protein-protein and protein-substrate interactions involved in the two-stage non-classical pathway recrystallization followed by SbpA units. As a result, two dimensional, crystalline nanometric sheets in a highly ordered tetrameric state (p4) can be formed on top of different surfaces. The use of iron in its ferrous state (Fe2+) as self-assembly inducing candidate has been omitted so far due to its instability under aerobic conditions, tending to natural oxidation to the ferric (Fe3+) state. In this work, the potentiality of assembling fully functional S-layers from iron (II) salts (FeCl2 and FeSO4) is described for the first time. A combination of chemical (oxidation retardants) and electrical (−1 V potential) factors has been applied to effectively act against such an oxidizing trend. Formation of the respective crystalline films has been followed by means of Electrochemical Quartz Crystal Microbalance with Dissipation (EQCM-D) measurements and complementary Atomic Force Microscopy (AFM) topography studies, which prove the presence of squared lattice symmetry at the end of the recrystallization process. Both techniques, together with additional electrochemical tests performed over the ion permeability of both types of S-layer coatings formed, show the influence of the counterion chosen (chloride vs. sulphate) in the final packing and performance of the S-layer. The presence of an underlying Secondary Cell Wall Polymer (SCWP) as in the natural case contributes to pair both systems, due to the high lateral motility freedom provided by this biopolymer to SbpA units in comparison to uncoated substrates.

Testo completoAbstract (sommario):
The genus Piper is an important component of tropical forests worldwide. Many Piper species have been reported as self-compatible (Figueiredo & Sazima 2000), and many have the ability to reproduce asexually, forming clonal aggregations (Grieg 1993). Furthermore, the main dispersers of Piper (bats) transport whole infructescences to feeding roosts (Fleming & Heithaus 1981), tending to disperse closely related seeds in clumps. These characteristics of Piper biology are likely to result in populations with strongly marked spatial genetic structure, and raise the potential for inbreeding depression through self-fertilization. A few studies using allozymes to evaluate spatial genetic structure in Piper spp. support this view. These studies indicate that populations separated by more than 1 km are genetically distinct (high FST values; Wright 1943) and that for some species inbreeding could be substantial (high values of FIS and FIT; Heywood & Fleming 1986, Mariot et al. 2002). However, the contributions of limited pollen and seed dispersal to generating spatial genetic structure remain unknown. Estimates of seed dispersal probabilities by Carollia perspicillata (Phyllostomidae) bats on Barro Colorado Island (BCI), Panama, and at Santa Rosa, Costa Rica, indicate that Piper dispersers move most seeds 50–300 m from the parent plant, with occasional long-distance events of > 1 km (Fleming 1981, Thies 1998). However, no studies have assessed how far Piper flower visitors move pollen. If seed dispersal is limited, and clonal reproduction is common, then long-distance pollen transfer may play a critical role in preventing inbreeding depression in Piper populations.

Abstract Value production is one of the most important information for comparing different tree species composition and management strategies in forestry. Although the value production of forest stands is affected by various factors thinning can be considered as one of the most important one. This paper aims at the evaluation of qualitative and value production in mixed Norway spruce (Picea abies [L.] Karst.), silver fir (Abies alba Mill.) and European beech (Fagus sylvatica L.) stands, which were managed by crown thinning for a period of 44 to 50 years and/or left to self-development. More than 1,500 individual trees aged from 61 to 132 years from 15 subplots established in western part of the Low Tatras Mts. and the Great Fatra Mts. in Slovakia were assessed. The proportion of stems in the highest quality A (stem quality classes) reached a low percentage, i.e. 12% in beech, 28% in spruce and 13% in fir out of the number of evaluated trees. The percentage of the highest quality log classes (assortments I + II) of beech ranged from 0 to 23% and of coniferous ones from 2 to 12%. Regarding the management method used, this percentage accounted for 0.1 to 23% for plot with self-development, whereas in plots with tending it was from 1 to 23%. Value production of coniferous tree species was always higher compared to beech, regardless of the management method. Regarding individual tree species, we found the highest value production in fir (81.4 € m−3) and the lowest in beech (46.5 € m−3).

"The synergetic modulation of the excitability of central gray matter by a neuropeptide: two protocols using excitation waves in chick retina". Anais da Academia Brasileira de Ciências 81, n. 1 (marzo 2009): 39–49. http://dx.doi.org/10.1590/s0001-37652009000100006.
Testo completoAbstract (sommario):
The isolated chick retina provides an in vitro tissue model, in which two protocols were developed to verify the efficacy of a peptide in the excitability control of the central gray matter. In the first, extra-cellular potassium homeostasis is challenged at long intervals and in the second, a wave is trapped in a ring of tissue causing the system to be under self-sustained challenge. Within the neuropil, the extra-cellular potassium transient observed in the first protocol was affected from the initial rising phase to the final concentration at the end of the five-minute pulse. There was no change in the concomitants of excitation waves elicited by the extra-cellular rise of potassium. However, there was an increase on the elicited waves latency and/or a rise in the threshold potassium concentration for these waves to appear. In the second protocol, the wave concomitants and the propagation velocity were affected by the peptide. The results suggest a synergetic action of the peptide on glial and synaptic membranes: by accelerating the glial Na/KATPase and changing the kinetics of the glial potassium channels, with glia tending to accumulate KCl. At the same time, there is an increase in potassium currents through nerve terminals.

Introduction: Several studies have shown that a dentist’s gender and nationality are important factors for patients when they choose their dentist. This topic is important in countries like Saudi Arabia, which is considered to be conservative and has many cultural boundaries that separate men from women in daily activities. Aim: This study aimed to investigate patient preference for a dentist’s gender among a sample population in Jeddah, Saudi Arabia. Methods: This cross-sectional study recruited 1,000 participants who completed a self-administered questionnaire. Data were analyzed using SPSS v.21. Results: A total of 46.2% of the participants had no particular gender preference for dentists in general, while 28.6% prefered male dentists and 25.2% prefered female dentists. Male and female participants had statistically significant differences in the selection of a dentist’s gender in general, with all participants tending to choose a dentist of the same gender as themselves. Previous personal experience and recommendations from friends were among the most influential factors in choosing dentists of a specific gender. In terms of preferences for dentists of a particular nationality, 45.6% had no preferences, while 28.4% preferred Saudi dentists. Conclusion: Although half of the Jeddah residents participating in our study had no preference for dentists of a particular gender or nationality, the other half had specific preferences.
