Episodic Memory bias in People with General Health and People Without it

Introduction: Health is one of the categories in which it needs to look a spectrum or continuum, both physically and morally. Health is feeding good and not being sick. Many factors affect the sustain ability of health, one of the important factors is cognitive (memory) factors. Because episodic memory plays on important role in recording a person’s personal experience related to time and place. Memory bias means more or less, orientation and recall, or positive or negative and the purpose of research is to examine this bias. Methods: The research method in this research is causal-comparative or causal, because it refers to cases where the reason has happened and researcher cannot manipulate them. The research data is collected from healthy and unhealthy people to the Williams test and then by causal research method statistical method analysis of variance (ANOVA) analyzed. Results: Memory is a cognitive function that plays an important role in individual activities. Any wrongdoing in the memory system, including bias can provide the context of other cognitive functions and to threaten the public health. Therefore, it can be concluded that the intellectual functions of individuals affect their mental and behavioral performance. Conclusion: Intellectual functions of individuals affect and behavioral performance orientation.

Re-evaluation of neurobehavioural toxicity of clothianidin using statistical methods for ordered alternatives assuming dose-response effect

Neurobehavioural toxicity of clothianidin in previous studies was re-evaluated using statistical methods for ordered alternatives assuming a dose-response effect. In a maternal exposure study, clothianidin was added into the diet to provide levels of 0% (control), 0.002%, 0.006% and 0.018% during the gestation and lactation periods in mice. In exploratory behaviour of male offspring in the F1 generation, average speed increased significantly in a dose-related manner in the Jonckheere test. Total distance lengthened in the high-dose group and average speed increased in the high-dose group in the Shirley–Williams test. In a two-generation toxicity study, clothianidin was added in the diet to provide levels of 0% (control), 0.003%, 0.006% and 0.012% from 5 weeks of age of the F0 generation to 11 weeks of age of the F1 generation in mice. The exploratory behaviour of adult males in the F0 generation, the average time of movement, and the number of rearing and rearing time increased significantly in a dose-related manner in the Jonckheere test. The average speed increased in the middle- and high-dose groups, number of rearing increased in the high-dose group and rearing time lengthened in middle- and high-dose groups in the Shirley–Williams test. These results suggest that the use of the appropriate statistical methods adjusted to the objectives of the study and the characteristics of the data could provide more definite conclusions.

Statistical approach for …a test chemical is considered to be positive… in regulatory toxicology: Trend and pairwise tests

In regulatory toxicology an outcome is claimed positive when both a trend is significant and any pairwise test against control. Two statistical approaches are proposed: a joint Dunnett and Williams test (assuming the dose as a qualitative factor) and a joint test of the Tukey regression test and Dunnett test (assuming the dose as a quantitative covariate).

The Poetics of Popular Poetry in the Argosy

This chapter focuses on the poetics of popular poetry in the Argosy under the editorship of Isa Craig. It argues that a careful reading of the periodical’s sentimental poetry challenges the critical dismissal of such light, entertaining verse as simplistic, marginal, and trite. In particular, it considers how the periodical poems of Christina Rossetti, Isa Craig, Jean Ingelow and Sarah Williams test as well as champion the conventions of the sentimental lyric form to produce a new poetics, one defined both through and against conventional representations of the Victorian poetess and her gushing, heart-inspired poetry. Ultimately, this chapter suggests that evaluating the poems of the Argosy on their own merits as poetic forms produced as part of the era’s complex, interconnected literary culture provides a way to discuss sentimental poetry and female poets without falling back on the defensive and sometimes dismissive language found in much of the critical work published on women’s popular poetry.

Direction of Capsular Strain Implies Surgical Repair Following Recurrent Anterior Shoulder Dislocation

Objectives: Capsular plication is often performed in addition to arthroscopic Bankart repair. However, little is known regarding the direction of capsular injury making the direction of plication fairly arbitrary. This study aimed to determine the optimal direction for capsular plication within four sub-regions of the inferior glenohumeral capsule following multiple dislocations. Methods: Seven fresh-frozen cadaveric shoulders (age range 48-66 yrs) were dissected free of all soft tissue except the glenohumeral capsule. A grid of strain markers was affixed to the anterior and posterior band (A/PB) of the inferior glenohumeral ligament (IGHL), and the axillary pouch. The position of the markers while the capsule was inflated with minimal pressure served as the reference state. The humerus and scapula were then mounted in a 6 degree-of-freedom robotic testing system. At 60 degrees of abduction and 60 degrees of external rotation of the glenohumeral joint, an anterior load was applied to reach an anterior translation of one half the maximum AP width of the glenoid plus 10 mm. This definition of dislocation resulted in non-recoverable strain and a reproducible Bankart lesion. Following 1, 2, 3, 4, 5 and 10 dislocations, the positions of the strain markers were again recorded with the capsule inflated. The difference in these positions compared to the reference state defined the non-recoverable strain. The strain map was split into four sub-regions, the anterior band of IGHL (AB), anterior axillary pouch (AA), posterior axillary pouch (PA), and the posterior band of IGHL (PB) (Fig. 1). The angle of deviation between each of the maximum principle strain vectors and the AB-IGHL or PB-IGHL for the anterior and posterior regions of the capsule were determined using ImageJ. Circular statistics were employed to calculate mean direction of each sub-region and a Watson-Williams test was performed to compare mean direction among each dislocation with significance set at p < 0.05. The mean direction of all strain vectors in each sub-region was categorized as parallel or perpendicular to the AB-IGHL or PB-IGHL serving as the clinical reference. Direction ranging from 0 to 45 or 135 to 180 degrees was categorized as parallel. Direction ranging between 45 and 135 degrees was categorized as perpendicular. Results: The direction of 81.8% of the AB sub-regions was categorized as parallel and 18.2% categorized as perpendicular to the AB-IGHL. Direction of 61.3% of the AA sub-region was categorized as parallel (Table 1) and 38.7% categorized as perpendicular to AB-IGHL. The direction of 33.3% of the PA sub-region was categorized as parallel and 66.7% categorized as perpendicular to the PB-IGHL. The direction of 21.4% of PB sub-region was categorized as parallel and 78.6% categorized as perpendicular to PB-IGHL. A Watson-Williams test demonstrated that the direction of 81.3% of the sub-regions were not significantly different (p > 0.05) among dislocations for each specimen (Table 1). Conclusion: The non-recoverable strain in most of the AB and AP sub-regions were categorized as parallel to the AB-IGHL while for the PA and PB sub-regions mostly perpendicular to the PB-IGHL. These findings imply that it may be more optimal to plicate the anteroinferior capsule parallel to the AB-IGHL while posteroinferior capsular plication, which is often not classically considered for plication in the setting of anterior instability, may also be necessary and best performed perpendicular to the PB-IGHL.

Ingestive behavior of sheep fed Brazil nut cake in the diet

This study evaluated the ingestive behavior of sheep when fed a corn-silage-based diet with varying levels (0%, 15%, 30%, and 60%) of Brazil nut cake (NC) (Bertholletia excelsa Bonpl.). Sixteen mongrel sheep with an average weight of 33 ± 6.04 kg were randomly distributed between four treatments. Data were tested for assumptions of normality, subjected to an analysis of variance, and adjusted in regression equations and by Williams’ test, to estimate the W point. The voluntary intake of dry matter (DM) and insoluble neutral detergent fiber (NDF) decreased linearly (P = 0.013 and P = 0.002) by 5.0 g and 2.41 g d-1, respectively, for every 1% of NC added to the diet. The time the animals spent feeding (288.75 min d-1) was not significantly affected; time spent idle increased linearly (P= 0.0002) by 3.10 min, and time spent during rumination decreased linearly by 2.62 min (P = 0.001) for each 1% addition of the co-product. The number of ruminated boluses (NRB) displayed a decreasing effect (P = 0.004) of 4.61 d-1 for each 1% of NC. For ruminating chews, the time spent per bolus (37.5 sec) and the number per bolus (56.14) did not differ (P &gt; 0.05) between treatments. However, the total chewing time (TCT) decreased linearly (P = 0.002) by 0.05 h d-1 and the number of chews per day displayed a quadratic effect (P = 0.008), with a maximum value estimated at 17.5% of NC in the diet. Rumination efficiency did not differ between the treatments (101.95 g DM h-1 and 36.76 g NDF h-1). The feeding efficiency (FE) had a linear reduction (P = 0.045) of 0.42 g NDF h-1, but was similar for g DM h-1 (172.5). The daily intake of DM and NDF showed W points estimated at 51.96% and 30.67% NC, respectively. The variables NRB, TCT, and FE (g NDF h-1) had W points estimated at 56.64%, 56.19%, and 56.33% NC, respectively. The Brazil nut cake, when present at levels greater than 56% of the diet’s DM, affects the ingestive behavior of the animals, particularly rumination-related variables, and at levels of 30.67%, it begins to affect the consumption of NDF, primarily due to the ether extract content and the diet’s fiber source.

How to evaluate phase differences between trial groups in ongoing electrophysiological signals

A growing number of studies endeavor to reveal periodicities in sensory and cognitive functions, by comparing the distribution of ongoing (pre-stimulus) oscillatory phases between two (or more) trial groups reflecting distinct experimental outcomes. A systematic relation between the phase of spontaneous electrophysiological signals, before a stimulus is even presented, and the eventual result of sensory or cognitive processing for that stimulus, would be indicative of an intrinsic periodicity in the underlying neural process. Prior studies of phase-dependent perception have used a variety of analytical methods to measure and evaluate phase differences, and there is currently no established standard practice in this field. The present report intends to remediate this need, by systematically comparing the statistical power of various measures of “phase opposition” between two trial groups, in a number of real and simulated experimental situations. Seven measures were evaluated: one parametric test (circular Watson-Williams test), and three distinct measures of phase opposition (phase bifurcation index, phase opposition sum and phase opposition product) combined with two procedures for non-parametric statistical testing (permutation, or a combination of z-score and permutation). While these are obviously not the only existing or conceivable measures, they have all been used in recent studies. All tested methods performed adequately on a previously published dataset (Busch, Dubois & VanRullen, 2009). On a variety of artificially constructed datasets, no single measure was found to surpass all others, but instead the suitability of each measure was contingent on several experimental factors: the time, frequency and depth of oscillatory phase modulation; the absolute and relative amplitudes of post-stimulus event-related potentials for the two trial groups; the absolute and relative trial numbers for the two groups; and the number of permutations used for non-parametric testing. The concurrent use of two phase opposition measures, the parametric Watson-Williams test and a non-parametric test based on summing inter-trial coherence values for the two trial groups, appears to provide the most satisfactory outcome in all situations tested. Matlab code is provided to automatically compute these phase opposition measures.
