Speech Naturalness

The purpose of this study was to determine through psychophysical comparison of scaling data whether speech naturalness judgments of stutterers and nonstutterers from audiovisual recordings form a prothetic or a metathetic continuum. Comparison of direct magnitude estimation and equal-appearing interval scale data indicated that speech naturalness forms a metathetic continuum when observers judge audiovisual recordings, suggesting that either scaling procedure is valid for the quantification of this dimension. Ease of use, an existing body of comparative data from different clinics, and somewhat better reliability favor the interval scaling procedure.

Speech Naturalness

The purpose of this study was twofold: to determine through psychophysical comparison of scaling data whether speech naturalness is a prothetic or a metathetic continuum, and to examine the relationship between selected acoustic characteristics of the speech of nonstutterers and treated stutterers and listeners' judgments of their speech naturalness. Comparison of magnitude estimation and interval scaling data indicated that speech naturalness behaves like a metathetic continuum, suggesting that either scaling procedure is valid for the quantification of this dimension. The speech of the nonstutterers was judged more natural than the speech of the treated stutterers, and a global voice onset time (VOT) measure (averaged across places of articulation) and a sentence duration measure were found to be the acoustic parameters most highly correlated with and predictive of speech naturalness. These results suggest the possibility that stuttering treatments that employ strategies like gentle voicing onset and prolonged speech may result in somewhat slower posttherapy speech patterns characterized by prolonged VOTs that could influence listeners to judge the speech as more unnatural than the speech of nonstutterers.

Scale Data

Pearson residuals aid the task of identifying model misspecification because they compare the estimated, using data, model with the model assumed under the null hypothesis. We present different formulations of the Pearson residual system that account for the measurement scale of the data and study their properties. We further concentrate on the case of mixed-scale data, that is, data measured in both categorical and interval scale. We study the asymptotic properties and the robustness of minimum disparity estimators obtained in the case of mixed-scale data and exemplify the performance of the methods via simulation.

Simple Regression

This study aims to determine the effect of the board's knowledge of budget oversight at the Gorontalo City DPRD Secretariat. The method used to analyze the data in this research is simple regression. In testing hypotheses that use regression analysis requires that the data analyzed be at least interval scale data. The results of the study indicate that the knowledge of board members has a significant effect on budget oversight.

ABSTRAKKeberhasilan implementasi pertanian berkelanjutan tidak hanya terkait pada keamanan ketersediaanpangan secara nasional, tetapi juga terkait dengan peran penting sektor pertanian dalamperekonomian nasional. Unit-unit kegiatan usahatani yang berorientasi pada keberlanjutan usahaakan menjadi penggerak bagi perekonomian. Usaha pembesaran lobster merupakan salah satu unitkegiatan sektor perikanan yang memiliki kontribusi bagi perekonomian. Keberhasilan usahapembesaran lobster yang berkelanjutan dipengaruhi oleh keterlibatan beberapa pihak termasukpetani. Petani merupakan subjek yang terlibat langsung dalam pelaksanaan konsep pembangunanpertanian berkelanjutan dilapangan. Persepsi petani terhadap keberlanjutan usaha bisa menjadi tolokukur keberhasilan pertanian berkelanjutan di tingkat usahatani. Penelitian ini bertujuan untukmenganalisis tingkat keberlanjutan menggunakan indeks komposit dari data skala likert persepsipetani terhadap keberlanjutan usaha pembesaran lobster. Data skala likert yang merupakan skalaordinal ditransformasikan ke dalam skala interval menggunakan pendekatan Method of SuccesiveInterval (MSI). Pengumpulan data dilakukan melalui survey kepada 106 petani lobster di PulauLombok Provinsi Nusa Tenggara Barat menggunakan kuesioner terstruktur. Hasil penelitianmenunjukkan bahwa nilai indeks persepsi keberlanjutan untuk dimensi ekonomi, sosial danlingkungan masing-masing masuk pada katagori keberlanjutan “sedang” dengan nilai rata-rataadalah 0.58; 0.56 dan 0.54. Indeks gabungan yang merupakan interaksi antara ketiga dimensimemiliki rata-rata 0.56 juga masuk pada katagori “sedang”.Kata kunci : pertanian berkelanjutan, indeks keberlanjutan, persepsi petani, budidaya lobsterABSTRACTThe successful of sustainable farming implementation is not only related to the security of foodsupply, but also to the contribution to national economy. Sustainability oriented farming will becomea motor for the economy. One of contributing unit is lobster farming. The success of sustainablelobster farming is affected by the involvement of multiple parties, including the farmers. Farmers arethe subject who directly involved in implementing the concept of sustainable agriculturaldevelopment. The farmers’s perception of sustainability is a benchmark of successful sustainableagriculture at the farm level. This study aimed to analyze sustainability level by using the compositeindex of the likert scale data on the perception of farmers towards farming sustainability. Likertordinal scale data is transformed into interval scale using Method of Successive Interval (MSI).Data collected through a survey to 106 farmers in Lombok Island, West Nusa Tenggara provinceusing a structured questionnaire. The results suggest that the value of the index of sustainabilityperception for the economic, social and environment each fall into”moderate” category with theaverage value is 0.58, 0.56 and 0.54 respectively. The Composite index, interaction between aspects,have an average of 0.56 is also fall into the “moderate” category.Keywords: sustainable agriculture, sustainability index, farmers perception, lobster farming
