Attachment Behaviour

The study investigated equine responses to novelty and handling, aiming to reveal whether horse–human relationships reflect criteria of an attachment bond. Twelve adult Standardbreds were subjected to a fear-eliciting test (novel objects presented close to two humans) and a handling test (being led passing novel objects) to study attachment-related behaviours and ease of handling. The tests were performed both before (pre-test) and after (post-test) horses had been trained by the same female handler (10 sessions of 15 min). Horses were assigned to three groups of four, each of which underwent different operant conditioning protocols: negative reinforcement (NR; pressure, release of lead, and whip tap signals) or combined NR with either positive reinforcement using food (PRf) or wither scratching (PRs). Results showed that neither familiarity of the person nor training method had a significant impact on the horses’ behavioural responses in the post-tests. However, horses showed decreased heart rates between pre- and post-tests, which may indicate habituation, an effect of training per se, or that the presence of the familiar trainer served to calm the horses during the challenging situations. There were large individual variations among the horses’ responses and further studies are needed to increase our understanding of horse–human relationships.

Global Reduction

BackgroundCentral to understanding of the behavioural consequences of depression has been the theory that the disorder is accompanied by an increased sensitivity to negative compared with positive reinforcement (negative bias), whereas other theorists have emphasized a global reduction in sensitivity to reinforcement in depression (blunting).MethodIn this study, we used a probabilistic selection task that was designed to examine independently rates of learning to predict both positive and negative reinforcement. Twenty-three depressed out-patients and 23 healthy controls from the local population participated in the study.ResultsNo evidence for a negative bias was observed on the task, either during acquisition of the task or during generalization of the learned information. Depressed patients responded slower on the task than controls but showed a similar modulation of reaction times (RTs) as controls following reinforcement. Evidence for blunting was observed on the training phase, as reflected in reduced trial-by-trial adjustment during this phase. However, this effect was related specifically to the severity of anhedonia, as measured by the Snaith–Hamilton Pleasure Scale (SHAPS), and was independent of overall depression severity.ConclusionsWe argue that the observation of a negative bias or blunting in a group of depressed patients may be dependent on the neuropsychological task and the symptoms of the patients tested. Our results provide insight into how these theories might be further tested.

Lactate Output

We measured cerebral metabolic rate of oxygen (CMRO2), cerebral blood flow (CBF), and cerebral lactate output during rest, during the execution of mental arithmetic, and during mental stress induced by physical and psychological annoyance. Measurements were performed in healthy volunteers by use of the Kety-Schmidt technique with 133Xe as the inert gas. Electroencephalographic desynchronization and highly significant increases in plasma catecholamines and heart rate verified that the test measurements were performed during conditions differing distinctly from the resting state. In accordance with an earlier study (Sokoloff et al. J. Clin. Invest. 34: 1101–1108, 1985), a minimal and nonsignificant 1% reduction of global CMRO2 during mental arithmetic was observed, signifying that this form of mental activation was unassociated with any detectable increase in overall cerebral synaptic activity. Mental stress induced a slight but highly significant (P less than 0.002) 6% reduction in global CMRO2. This finding is in contrast to results from earlier investigations and contradicts the generally accepted notion of an association between mental arousal and a diffuse upregulation of cerebral synaptic activity. During mental arithmetic and mental stress, cerebral lactate output increased by 207 and 344%, respectively, but because of large individual variations in the measured responses, the elevations reached statistical significance only during mental arithmetic.

Smoking Patterns

Majority of smokers who begin smoking as adolescents are at risk for developing smoking patterns. Misperception has contributed that smokers underestimate the risks related with smoking. The aim of this study was to identify the gender differences in adolescents’ perception about smokers based on four factors. A total of 863 respondents consist of 302 male (age 21.2 ± 0.56 year) and 562 female (age 20.9 ± 0.66 year) were participated in this study. They were asked to complete a Short-Form Smoking Consequences Questionnaire (S-SCQ) in this study. The result showed female adolescence reported significantly higher discontentment rate (negative perception) for smoking compared to male. There are all four factors were affected on smoking perception relative gender included negative consequence (z=-6.321, p<0.0001), positive reinforcement (z=- 8.110, p<0.0001), negative reinforcement (z=-7.584, p<0.0001) and appetite-weight control factor (z=-6.142, p<0.0001). Female tend to have negative perception on smoking behavior compared to male that encourage the higher number of male smoker than female adolescents. In conclusion, misconceptions about the consequence and reinforcement regarding smoking are widespread among adolescent under this study. Hence, significant public anti-smoking is vital to redress these misperceptions

Welfare Implications

AbstractDomestic dogs are trained using a range of different methods, broadly categorised as reward based (positive reinforcement/negative punishment) and aversive based (positive punishment/negative reinforcement). Previous research has suggested associations between use of positive punishment-based techniques and undesired behaviours, but there is little research investigating the relative welfare consequences of these different approaches. This study used a judgement bias task to compare the underlying mood state of dogs whose owners reported using two or more positive punishment/negative reinforcement based techniques, with those trained using only positive reinforcement/negative punishment in a matched pair study design. Dogs were trained to discriminate between rewarded and unrewarded locations equidistant from a start box, and mean latencies recorded. Their subsequent latency to intermediate ‘ambiguous’ locations was recorded as an indication of whether these were perceived as likely to contain food or not. Dogs trained using aversive methods were slower to all ambiguous locations. This difference was significant for latency to the middle (Wilcoxon Z = − 2.380, P = 0.017), and near positive (Wilcoxon Z = − 2.447, P = 0.014) locations, suggesting that dogs trained using coercive methods may have a more negative mood state, and hence that there are welfare implications of training dogs using such methods.

The objective of the study is to identify: (1) the influence of Tabata training from the perspective of “Good” category in preliminary VO2Max level; (2) the influence of Tabata training from the perspective of “Moderate” category in preliminary VO2Max level; (3) the influence of Tabata training from the perspective of “Poor” category in preliminary VO2Max level; and (4) the appropriate preliminary VO2Max level that should be assigned on the Tabata training method. Looking at the objective of the study, the nature of the study is indeed quantitative while the method that had been implemented is the quasi-experimental research with non-equivalent (pre-test and post-test) control group design. Within the conduct of the study, the number of the sample that had been involved was 60 respondents and these samples were gathered by means of quota sampling. Then, the data that had been gathered were analysed by using the paired sample t-test in order to test the hypotheses that had been assigned. The results of the study show that the Tabata training method is appropriate to be assigned in the “Moderate” category of preliminary VO2Max level. Departing from the conclusion, it might be implied that the study might be conducted further by adding the number of the sample and by adding the different type of samples.

This research focuses on the effect of reinforcement during English Language Learning (ELL) classroom activities of Bangladeshi primary level education. The findings of the research indicate that teachers follow both positive and negative reinforcement as part of their teaching-learning activities depending on the actual situation of the class. Positive reinforcement helps students to enhance their mental growth and also boost their learning behaviour. There are some negative influences on students’ behaviour when the teacher treats them with any kind of negative reinforcement. Although all the teachers believe that positive reinforcement helps to improve motivation, self-confidence, classroom participation, teacher-student relationship and effective learning of students during ELL classroom activities, a few teachers still use negative phrases which demotivate students towards learning rather than creating the eagerness to learn.

The research aimed to analyze the student’s learning behavior in isolated school it was conducted in a qualitative approach in SMPN SatapTojabi, Babussalam, Lasusua Sub District, North Kolaka District, South east Sulawesi it was one of the isolated schools in North KolakaDistric, located on the mountain it was about eight kilometers from the level of land with no electricity, people still used solar power for doing an activity related to electricity. The subject was the third grade students in the academic year 2019 – 2020 with 14 students. The data was collected by using observation and interview. The result showed that they gave various behaviors, some of them were diligent, obedient, and polite some of them were lazy, always messing about, and denying. By giving positive reinforcement students were not eager to get the reward even though the teacher promised a special reward some of them were still not change the behaviors. These behavior such as did not do the homework on time, messing about when their friends start to work, do not come at class on time, and keep the class noisy. While by giving negative reinforcement some students still much less discipline and less concern about their education.

Soccer Training

Small sided-games training is a small-scale field, an appropriate situation developed for young players, so they can learn and develop. Small sided games training is also one of the methods of soccer training using smaller fields with fewer players. This training method  is a fairly effective exercise in physical improvement, techniques and tactics Passing is to feed the ball or pass the ball to a friend, while passing determination is the ability to set goals / pass the ball according to the goal or target. This research is an experimental research conducted with the aim to find out whether or not there is a result of something done on the sample to be studied. The research began with a pretest and ended with a posttest. The number of samples in this study amounted to 20 people. The training given was done during 16 meetings. This research was tested using a statistical analysis of the hipotsis test (t test). Based on data analysis, it can be concluded that the small sided games exercise gives a significant effect on the accuracy of passing on extracurricular students at SMP Negeri  1 Muaro Jambi, proven in the pre-test and post-test assessments with an average pre-test = 505 and post-test = 7.65, with the increment difference of 7.65.

Abstract We describe a simple method for determining glycated lipoproteins (glc LPs) in serum by agarose gel film electrophoresis, with color development with nitroblue tetrazolium. The resulting blue bands on the film were measured densitometrically at 545 nm to quantify alpha-, pre beta-, and beta-glc LPs. Each glc LP concentration (mmol/L) was calculated from the resulting percentage multiplied by the value for serum fructosamine. Only glc beta-LP was significantly correlated with the atherogenic index: low-density LP-cholesterol/high-density LP-cholesterol (r = 0.545, P less than 0.01). The concentration of glc beta-LP in sera from diabetics was 2.2-fold higher (0.84 mmol/L) than that (0.38 mmol/L) in normal individuals. Diabetic patients with complications had higher concentrations of glc beta-LP, with large individual variations, than did patients without complications, the greatest concentration (1.02 mmol/L) being found in patients with diabetic retinopathy and (or) nephropathy. The concentration of glc beta-LP (glc LDL) in serum seems to depend on the extent and duration of hyperglycemia; it may also be a useful diagnostic indicator of diabetic atherogenesis, microangiopathy (e.g., retinopathy or nephropathy), and other complications.

Abstract We have assessed individual variations in urinary acidic metabolite excretion and the effects of extreme alterations in dietary composition on these metabolites in selected normal persons who we considered representative of the general ambulant normal population. Extreme dietary alterations produced relatively small changes in the patterns or amounts of metabolite excretion, but large individual within-subject variations were observed. Our results indicate that variation in the ranges of excretion for the normal population mainly depend on individual metabolic variations rather than on dietary factors, and provide a basis for the assessment of the normal ranges determined from population surveys. Our results are discussed in relation to previous studies on the variability of urinary acidic metabolite excretion in man.
