Identification of Types and Levels of Pests Attack on Palm Plantation Seedlings (Elaeis guineensis Jacq) at PT. Sentosa Kalimantan Jaya, Berau District East Kalimantan Province. Under the guidance of Iin Arsensi and Purwati. This study aims to determine the types of pests that attack oil palm seedlings, the frequency and intensity of oil palm pest attack on the Main Nursery stage nursery. The research was arranged in Survey method, determining 5 research plots in one block diagonally by marking on each plot with plastic marker of seeds, so obtained 15 research plots contained in 3 block that is block J, I and D. Each research plot consists of 30 Oil palm seedlings so that the number of observed 450 seeds of oil palm. The results showed that the types of pests that attack the oil palm seedlings in Main Nursery are Tungau (Tetranychus piercei), Adoretus compressus Beetle, and Locusta migratoria manilensis (Locusta migratoria manilensis); Block Frequency A pest attack in the category of minor attacks is 51.33%, 24% attack, while the intensity of pest attacks is a mild attack category; Frequency of Block I attack of pests in light attack category is 49,33%, moderate attack 37,33%, heavy attack 2%, while intensity of pest attack moderate attack category; Frequency of Block D attack of pest in light attack category is 41,3%, moderate attack 41,3%, severe attack 7,3%, while intensity of pest attack moderate attack category;

The purpose of this study  is to improve the communication skills of students through the TPS (Think Pair Share) learning model. the results of observations show communication skills of grade 3 students in SDN Ledok 05 Salatiga is still low. the results of interviews with grade 3 teachers from 29 students in the High category only about 31% who dared to present or communicate in front of the class with confidence. While in the medium category only 24% and 45% of other students in the low category are still afraid if they get the opportunity to communicate to appear in public or in front of the class. The research method uses PTK (Class Action Research). Techniques for collecting data through observation, interviews, questionnaires. The instruments used are indicators of five components of interpersonal or interpersonal communication skills which include openness, empathy, supportive attitude, positive attitude, equality. Research uses quantitative descriptive. The results showed that the first cycle of the high category had a frequency of 18 with a percentage of 62%, medium category frequency 6 and a percentage of 21%, and a low category 5 with a percentage of 17%. Whereas for the second cycle the high frequency category was 20 with a percentage of 69%, medium category 8 with 28%, and low category 1 with a percentage of 3%. Class 3 communication skills at SDN Ledok 05 Salatiga increased after using TPS (Think Pair Share) models.

Categorization and generalization are fundamentally related inference problems. Yet leading computational models of categorization (as exemplified by, e.g., Nosofsky, 1986) and generalization (as exemplified by, e.g., Tenenbaum & Griffiths, 2001) make qualitatively different predictions about how inference should change as a function of the number of items. Assuming all else is equal, categorization models predict that increasing the number of items in a category increases the chance of assigning a new item to that category; generalization models predict a decrease, or category tightening with additional exemplars. This paper investigates this discrepancy, showing that people do indeed perform qualitatively differently in categorization and generalization tasks even when all superficial elements of the task are kept constant. Furthermore, the effect of category frequency on generalization is moderated by assumptions about how the items are sampled. We show that neither model naturally accounts for the pattern of behavior across both categorization and generalization tasks, and discuss theoretical extensions of these frameworks to account for the importance of category frequency and sampling assumptions.

This study investigated sentence-processing strategies adopted by advanced nonnative speakers (NNSs) and native speakers (NSs) of English in the context of an English structure with which NNSs reportedly have an acquisition difficulty (e.g., Swan & Smith, 2001)—namely, modal perfect (MP). Participants read MP sentences such as He could have worked at the shoe factory and closely related analogous sentences (e.g., He could have work at the shoe factory), and reading times and errors were measured in an online grammaticality-judgment task. It was hypothesized that NSs would have a processing preference for MP sentences compared to the analogues, reflecting the primacy of syntactic information in NS processing and a preference for late closure, whereas NNSs would show no such preference because they rely less on syntactic information when processing sentences. The results revealed, however, that both NSs and NNSs read MP sentences more quickly and with fewer errors than the closely related analogues, consistent with a processing preference for MP sentences. Both groups were also influenced by word-category frequency information, which moderated, but did not fundamentally alter, their syntactic preference for MP. The significance of these findings is discussed in terms of models of second-language sentence processing and NNSs’ reported MP acquisition difficulty.

We investigated strong-verb paradigm leveling in German, Dutch, English, and Swedish, and found significant differences in ablaut leveling and class change towards the weak conjugation. Swedish favors ablaut patterns retaining a difference between the preterite and the past participle, while German, Dutch, and English favor a common vowel for both forms. In change from the strong to the weak conjugation in Swedish, the preterite is more resistant than the past participle, while in the other languages it is the reverse. We provide a unified explanation for these facts based on differences in category frequency due to the prominence or lack of an aspectual distinction between preterite and perfect.*
