This experiment compares the yes-no and forced recognition tests as methods of measuring familiarity. Participants faced a phase of 3 study-test recognition trials in which they studied words using all the letters of the alphabet (overlapping condition, O), and an additional phase in which targets and lures did not share any letters (non-overlapping condition, NO). Finally, subjects performed a forced-choice task in which they had to choose one of two new words, each from one of the subsets (Parkin et al., 2001). Results in the NO condition were better than in the O condition in the yes-no recognition test, while the forced-choice rate was significantly higher than .50, showing their sensitivity to familiarity. When the letter set of the words for study in the third list of the NO condition was switched, the difference between NO and O conditions disappeared in yes-no test, while the force-choice rate was not higher than .50. We conclude that both the yes-no test and the forced-choice test are valid and equivalent measures of familiarity under the right conditions.

Two experiments investigated the information conveyed by intonation from speaker to listener. A multiple-choice test was devised to test the ability of 48 adults to recognize and label intonation when it was separated from all other meaning. Nine intonation contours whose labels were most agreed upon by adults were each matched with two English sentences (one with appropriate and one with inappropriate intonation and semantic content) to make a matching-test for children. The matching-test was tape-recorded and given to children in the first, third, and fifth grades (32 subjects in each grade). The first-grade children matched the intonations with significantly greater agreement than chance; but they agreed upon significantly fewer sentences than either the third or fifth graders. Some intonation contours were matched with significantly greater frequency than others. The performance of the girls was better than that of the boys on an impatient question and a simple command which indicates that there was a significant interaction between sex and intonation.

The difference between intent (dolus) and negligence (culpa) was rarely emphasized in codified medieval laws and regulations. When compared to the legal statements related to intent, negligence was mentioned even more rarely. However, there are some laws that distinguished between the two concepts in terms of some specific crimes, such as arson. This paper draws attention to three medieval Slavic legal documents – the Zakon Sudnyj LJudem (ZSLJ), the Vinodol Law and the Statute of Senj. They are compared with reference to regulations regarding arson, with the focus being on arson as a crime committed intentionally or out of negligence. The ZSLJ as the oldest known Slavic law in the world shows some similarities with other medieval Slavic legal codes, especially in the field of criminal law, since most of the ZSLJ’s articles are related to criminal law. On the other hand, the Vinodol Law is the oldest preserved Croatian law and it is among the oldest Slavic codes in the world. It was written in 1288 in the Croatian Glagolitic script and in the Croatian Chakavian dialect. The third document – the Statute of Senj – regulated legal matters in the Croatian littoral town of Senj. It was written in 1388 – exactly a century after the Vinodol Law was proclaimed. When comparing the Vinodol Law and the Statute of Senj with the Zakon Sudnyj LJudem, there are clear differences and similarities, particularly in the field of criminal law. Within the framework of criminal offenses, the act of arson is important for making a distinction between intent and negligence. While the ZSLJ regulates different levels of guilt, the Vinodol Law makes no difference between dolus and culpa. On the other hand, the Statute of Senj strictly refers to negligence as a punishable crime. Even though the ZSLJ is almost half a millennium older than the Statute of Senj and around 400 years older than the Vinodol Law, this paper proves that the ZSLJ defines the guilt and the punishment for arson much better than the other two laws.

ABSTRACT This study aims to determine the effect of plant growth regulators and micro elements to cherelle wilt in cacao plants as well as finding the right business in tackling cherelle wilt in cacao plants. The research was carried out in the garden village folk Eris Eris Minahasa district for 8 months from January to August 2009. Spraying micro-nutrient elements is necessary to reduce cherelle wilt because the various treatments for the first observation is not significantly different, but the observations into two to seven observations to indicate a significant difference between treatments (percentage cherelle wilt on treatment without nutrient elements higher than sprayed). While spraying the treatment factor of plant growth regulators (NAA) is not necessary because the first observation and the two had no significant effect on the percentage of cherelle wilt affected only the third observation and further observations to a fourth, fifth, sixth and seventh again no effect. So is the treatment for fruit length and diameter showed that administration of the micro nutrients necessary for sprayed with micro nutrients result 22.10 cm higher than that is not sprayed is 19.43 cm. As for the diameter of the fruit is affected by plant growth regulators. Treatment is better than 200 ppm 100 ppm and 0 ppm (control).

Attribute Value

AbstractComparison-induced distortion theory (Choplin 2007; Choplin and Hummel 2002) describes how comparison words like “better” suggest quantitative differences between compared values. When a comparison word is used to contrast a personal attribute value with some standard (e.g. “Your score is better than average”), the comparison-suggested difference for the word may bias estimates or recall of personal attribute values. Three studies investigated how comparison-suggested differences determine the effect of social comparison on estimates or recall of personal attribute values. The first study demonstrated that estimates of attributes are biased towards (assimilation) or away from (contrast) a comparison standard depending on whether the difference between the compared attribute values exceeds or falls below the comparison-suggested difference. The second study showed that the comparison language selected by participants (through the difference suggested by the language) mediated the effect of standard similarity on attribute estimates following a social comparison. The third study demonstrated concurrent assimilation and contrast effects in recall of attribute values due to the size of the observed difference between the self and the standard for the attribute. Unlike in previous research on social comparison, assimilation and contrast patterns in these studies can be explained through a single process.

Abstract Background: With the ageing of China's population, the incidence and mortality of coronary atherosclerotic heart disease (CAD) is increasing year by year, which brings a heavy burden to the family and society [1]. We aimed to analyse the strategy of coronary artery bypass grafting (CABG) in the right coronary artery and to compare the haemodynamic characteristics of the sequential grafts with those of single grafts and to observe the patency rate of those grafts for one week after the operation.Methods: A total of 242 patients (178 men, mean age 62.6±8.8 years) underwent right coronary artery bypass grafting in our hospital from October 2016 to January 2019. The blood flow (Q, ml/min), pulsatility index (PI) and related parameters of the grafts were measured and recorded by TTFM during the CABG. The patency of the grafts was evaluated by coronary computed tomography (CT) for one week after the operation. Results: The most common material used for the graft in the right coronary system of CABG is the greater saphenous vein (92.3%), followed by the radial artery (5.5%) and the internal mammary artery (1.9%). The highest frequency target of the right coronary artery is the posterior descending artery (PDA) (47.6%), followed by the right main coronary artery (RCA) (29.1%) and the posterior branch of the left ventricle (PL) (23.3%). The proportion of single grafts was the highest for the right coronary artery in CABG (178 cases, 67.9%), followed by a graft of the PDA-PL (42 cases, 16.0%) and other sequential grafts among the different coronary artery systems (including the system of the left anterior descending artery (LAD) and the left circumflex (LCX)). Whether there were sequential grafts of the PDA-PL or other sequential grafts among the different systems of the coronary artery, the instantaneous flow of a group of sequential grafts was higher than that of a single graft, and the difference had statistical significance (P < 0.01). However, there were no significant differences in the flow between the groups of sequential grafts (P = 0.410). Diastolic flow (DF) in the group of sequential grafts of the right coronary system was better than that in the non-sequential group (P < 0.001), and the difference had statistical significance. There was no significant difference between the DF of the groups of the other system of sequential grafts and that of the right coronary sequential grafts. Coronary artery CT suggested that there were 11 cases of poorly developing grafts or stenosis and occlusion a week after the operation, and those phenomenon mainly occurred in the group with a single graft. There was only one case that was occluded in the group of other systems of sequential grafts, and statistically significant differences existed between the two groups (P < 0.01).Conclusions: In our centre, the most common form of CABG in the right coronary artery system is a non-sequential vein bridge to the PDA. Whether there are sequential grafts of the PDA-PL or other sequential grafts among the different coronary artery systems, the instantaneous flow of a group of sequential grafts is higher than that of a single graft. DF in the group of sequential grafts of the right coronary system was better than that in the non-sequential group.

Morphometric Characterization

The right conal (conus) artery either presents as the first ventricular branch of the right coronary artery (RCA) or arises directly from the aorta, in which case, it is considered the third coronary artery (TCA). Morphometric characterization of this artery is important for interpretation of coronarography, surgical revascularization of myocardium and embryological interpretations. Eight out of 23 hearts presented the TCA (34.8%). The difference in the frequency of the TCA between the sexes was statistically insignificant (p>0.05). In all the specimens, the ostium of the TCA was to the left of and superior to the ostium of the RCA. The supernumerary (third) coronary artery formed Vieussens' arterial ring in 50% of the cases with the TCA, while the conal branch of the RCA formed the anastomosis with the conal branch at a higher frequency (63% of the cases). The ratio of external diameters of the RCA and TCA was 2.84 ±0.78, while the ratio of external diameters of the RCA and its conal branch was 2.61±0.74. The difference in the ratios was statistically insignificant (p>0.05). There were no findings indicating that the presence of the TCA could be detrimental or advantageous when compared to the classical coronary scheme (right and left coronary arteries originating from the aortic sinuses). Based solely on the TCA's morphological features, there is insufficient evidence to suggest that the presence of the TCA per se, is associated with a known clinical or disease state.

ABSTRACTThis study aims to: analyze whether monetary fiscal policy affects the economy (GDP) of Indonesia and examine whether differences in the budget regime affect the fiscal fiscal governance in supporting the achievement of Indonesia's GDP. Research using quantitative analysis methods; The data used are time series 1990-2010, the analysis technique used is multiple regression with dummy variables. The results show that monetary stability - represented by the variable APBN, financing, investment, BI-rate, exports, imports, inflation, exchange rates and budget regime differences - simultaneously significantly influences GDP development. The level of correlation between the independent variables and the variable variable is quite strong with R-squared 0.9969%. This means that the research variables can explain the dynamics of GDP around 99.69%, the effect is influenced by other variables not examined. Partially, from the results of the statistical analysis, it was found that the APBN, investment, BI-Rate, Imports and the exchange rate had an effect and the difference in the budget system regime had a significant effect on the development of GDP. While the variable financing, exports and inflation have no significant effect on GDP. Cost variables can have a real impact if the standard error is raised to 19%. Exports can significantly affect GDP if the standard error is raised to 24%. APBN, investment, BI-Rate and budget regime differences are positively correlated to GDP. While imports and the exchange rate are negatively correlated to GDP. The econometric model of the influence of oneter stability with GDP is as follows: GDP $ = 0.3131 * APBN + 1.8437 * INVEST $ + 7.8384 * BI_RATE - 0.00037 * IMPORT - 0.01226 * EXCHANGE $ + 167.02356 * REZIM1 + 181.1681 * REZIM2 + 197.6315. Relatively, the use of an integrated and performance-based budgeting system is better than a balanced budget system. Likewise the performance-based budgeting system is also relatively better than the integrated budgeting system. This means that the budget system reform in Indonesia has been on the right track so far.Keywords: Indonesia, economy, GDP, budget system, monetary stability

The fact that always be considered is the contemplation of internal feelings of every practiced Muslim to please Almighty Allah. It occurs via observing and following His commands and orders through prescribed manner of the Messenger Muhammad Peace Be upon Him, but sometimes it becomes so complex and multipart to identify the right step of actions, streamline with shariah standards even difficult to recognize the difference between preferred and Non-preferred, lawful and prohibited. So among these situations, second congregational prayed in one masjid, an issue faced by common people. The classical literature is the witness of unanimous ruling in two situations of second congregational prayer; i.e. congregation (Jama’at) in the Masjid and congregation in public places. The third situation requires little deep understanding to know the actual ruling of shariah, which is congregation (Jama’at) in the same Masjid but appointed Imam performs original Jama’at. Different scholars have presented different opinions. This paper emphasis on the third situation where the detailed discussion has been made in the light of the mentioned book in the title to draw the neat and clear line of action for the practiced Muslim along with the provision of different narrations and Shariah rulings in order to interpret the reality and to avoid all sort of confusions.

Early word form representations are assumed to be unanalyzed 'routines'. Around age 2 1/2, when the first 50 to 100 words have been acquired, the organization of the mental lexicon starts to change. Word form representations are segmented into their constituent linguistic substructures: syllable and phonemes. Gradually the network-like structure which is thought to capture the mature mental lexicon emerges. Peters (1983, 1985) has proposed two heuristics that may be employed by children for segmenting words, both during this 'reorganization' and afterwards, when new words are acquired and inserted into the rapidly expanding lexicon. The first employs word stress, the second is based on matches between a new form and lexical items that have already been acquired. This study investigates in an experimental fashion whether children use stress and formal similarities in segmentation. Children (4, 5 and 6 yrs. old) were asked to alter syllable onsets in trisyllabic words with stress on either of the three syllables, and in trisyllabic complex words in which at least one morpheme could be expected to be known by the subjects. It appeared that word-internal onsets of stressed syllables were more often altered than onsets of unstressed syllables. These results are supportive of the 'stress' heuristic. Also, syllable onsets which coincided with word-internal lexical morpheme boundaries (i.e., boundaries between known and unknown parts which can also occur independently) were more often altered than non-boundary onsets. However, syllable onsets at root-suffix boundaries were not altered more frequently than non-boundary onsets. This difference between lexical morpheme boundaries and suffix boundaries is not predicted by a segmenting heuristic based on formal match. It is therefore suggested that in fact prosodic characteristics of the final morphemes in the complex words factors could be responsible for the difference: all first (or only) syllables of the right-hand lexical morphemes were stressable, whereas the suffixes were not. This conjecture was tested in a second experiment in which 7 and 8 year old children were asked to alter syllable onsets in derivations consisting of a bisyllabic root and a monosyllabic suffix. Some suffixes were stressed, others were unstressed and still others caused stress in the stem morphemes to be shifted to the second syllabe. It was found that stressed suffixes yielded more alterations than unstressed suffixes. Second, stressed syllables, in general, yielded more onset alterations than unstressed syllables, regardless of whether stress was assigned by the stem morpheme or by derivation with a stress-shifting suffix. Finally, syllables which had 'lost' stress as a result of dervational stress shift produced more alterations than unstressed syllables that were not stressed, in the stem morpheme either. These results support the conjecture that the apparent effects of formal match on segmentation behavior in the first experiment can be explained by reference to stress. Consequently, it is concluded that stress is the primary cue in word segmentation. This conclusion is in accordance with 'prosodic bootstrapping' theory, which claims that children are 'programmed' to use prosodic features as clues to linguistic structure.
