Understanding causal effects of a treatment is often of interest in the social sciences. When treatments cannot be randomly assigned, researchers must ensure that treated and untreated participants are balanced on covariates before estimating treatment effects. Conventional practices are useful in matching such that treated and untreated participants have similar average values on their covariates. However, situations arise in which a researcher may instead want to match on model parameters. We propose an algorithm, Causal Mplus Trees, which uses decision trees to match on structural equation model parameters and estimates conditional average treatment effects in each node. We provide a proof of concept using two small simulation studies and demonstrate its application using COVID-19 data.

Kualiti guru merupakan penentu utama kepada kecemerlangan murid dari segenap aspek kehidupan agar dapat bersaing di peringkat global. Kajian ini bertujuan untuk mengenal pasti perhubungan dan kesan amalan Kepimpinan Kendiri ke atas tahap amalan Gelagat Kewarganegaraan Organisasi guru-guru di Malaysia dan Efikasi Kendiri sebagai pembolehubah pengantara (mediating variable). Kajian ini melibatkan guru-guru yang mengajar di Sekolah Rendah Berprestasi Tinggi di seluruh Malaysia dan seramai 40 orang guru sebagai responden telah dipilih secara rawak dari setiap sekolah. Data kuantitatif ini dianalisa menggunakan Statistical Package for Social Sciences (SPSS) dan Structural Equation Model (SEM). Kajian mendapati bahawa tahap amalan Kepimpinan Kendiri, Efikasi Kendiri dan Gelagat Kewarganegaraan Organisasi adalah tinggi dengan skor min melebihi 5.0. Analisis dapatan juga menunjukkan bahawa Kepimpinan Kendiri dan Efikasi Kendiri mempengaruhi Gelagat Kewarganegaraan Organisasi sehingga 20%. Dapatan kajian juga menunjukkan bahawa terdapatnya hubungan yang signifikan antara kedua-dua pemboleh ubah iaitu Kepimpinan Kendiri dan Efikasi Kendiri dengan Gelagat Kewarganegaraan Organisasi guru-guru tersebut. Efikasi Kendiri telah bertindak sebagai pembolehubah separa mediator dalam hubungan antara Kepimpinan Kendiri dan Gelagat Kewarganegaraan Organisasi. Kajian ini diharap dapat membantu melahirkan pelajar yang cemerlang dan seimbang dengan mengetengahkan kualiti guru yang diperlukan supaya mereka dapat menghasilkan murid yang cemerlang dari segenap aspek kehidupan, seiring dengan Falsafah Pendidikan Negara. Hal ini jelas kerana didapati bahawa kualiti guru memainkan peranan yang terpenting bagi menentukan kejayaan seseorang murid. Kajian ini juga diharapkan dapat memberi gambaran yang lebih jelas terhadap peranan dan tanggungjawab guru setelah mengamalkan Gelagat Kewarganegaraan Organisasi. Seterusnya dapat mengurangkan konflik yang timbul akibat daripada berlainan jangkaan dan harapan daripada pelbagai pihak berkepentingan terhadap tugas serta tanggungjawab guru di sekolah.

Community Pressure

The authors develop and estimate a conceptual model of how different aspects of customers’ relationships with the brand community influence their intentions and behaviors. The authors describe how identification with the brand community leads to positive consequences, such as greater community engagement, and negative consequences, such as normative community pressure and (ultimately) reactance. They examine the moderating effects of customers’ brand knowledge and the brand community's size and test their hypotheses by estimating a structural equation model with survey data from a sample of European car club members.

The Social

Researchers in the social sciences often obtain ratings of a construct of interest provided by multiple raters. While using multiple raters provides a way to help avoid the subjectivity of any given person’s responses, rater disagreement can be a problem. A variety of models exist to address rater disagreement in both structural equation modeling and item response theory frameworks. Recently, a model was developed by Bauer et al. (2013) and referred to as the “trifactor model” to provide applied researchers with a straightforward way of estimating scores that are purged of variance that is idiosyncratic by rater. Although the intent of the model is to be usable and interpretable, little is known about the circumstances under which it performs well, and those it does not. We conduct simulation studies to examine the performance of the trifactor model under a range of sample sizes and model specifications and then compare model fit, bias, and convergence rates.

Abstrak-Penelitian ini bertujuan untuk menguji apakah film sangat penting dalam pengembangan Empathy, Nostlagia, Perceived Risk, Place Familiarity, Place Image yang dapat membentuk Attitude Towards dan Intention to Visit A place. Penelitian ini dilakukan dengan menggunakan Structural Equation Model(SEM) dan diolah dengan bantuan software Statistical Package for Social Sciences (SPSS) versi 23 dan AMOS 24. 200 responden diambil dari responden yang pernah menonton seri film Harry Potter lebih dari sekali, masih mengingat film Harry Potter yang pernah di tonton, masih mengingat pemandangan dari sekolah Hogwarts (Kastil Alnwick), dan mengetahui bahwa kastil Alnwick dipergunakan sebagai tempat wisata. Hasil penelitian menunjukkan bahwa Empathy, Nostalgia, Place Familiarity, Place Image merupakan faktor-faktor yang berpengaruh positif secara signifikan terhadap Attitude dan Intention pada kastil Alnwick. Perceived Risk merupakan faktor yang tidak berpengaruh secara signifikan terhadap Place Familiarity  di Kastil Alnwick. Para responden yang pernah menonton seri film Harry Potter memiliki Attitude yang positif dan memiliki Intention untuk mengunjungi kastil Alnwick Kata kunci: Perception, Movies, Destination Image, Risk, Intention, Familiarity.

Given the wide applications of photovoltaic (PV) power generation, the volatility in generation caused by solar radiation, which limits the capacity of the power grid, cannot be ignored. Therefore, much research has aimed to address this issue through the development of methods for accurately predicting inter-hour solar radiation and then estimating PV power. However, most forecasting methods focus on adjusting the model structure or model parameters to achieve prediction accuracy. There is little research discussing how different factors influence solar radiation and, thereby, the effectiveness of these data-driven methods regarding their prediction accuracy. In this work, the effects of several potential factors on solar radiation are estimated using correlation analysis and a structural equation model; an ensemble model is developed for predicting inter-hour solar radiation based on the interaction of those key factors. Several experiments are carried out based on an open database provided by the National Renewable Energy Laboratory. The results show that solar zenith angle, cloud cover, aerosols, and airmass have great effects on solar radiation. It is also shown that the selection of the key factor is more important than the model structure construction for predicting solar radiation precisely. The proposed ensemble model proves to outperform all sub-models and achieves about a 12% improvement over the persistent model based on the normalized root mean squared error statistic.

The public participation in evaluating the rail transit P&R facilities is beneficial for enhancing the objectivity of the evaluation and reflecting the social equity to the greatest degree, so that the decision-making can be more people-oriented. Based on the analysis of the P&R travelling features of sedan cars and the transfer facilities service level, this paper, from the perspective of the public evaluation, makes a structural equation model which shows the evaluation of sedan car travelers toward the transfer efficiency of rail transit P&R facilities and elaborates the identification, fitting, correction and applications of the model.
