ABSTRACT:Improving the quality of education becomes very important nowadays to meet the increasing demands of graduates’ future institutions. This research adopts five dimensions of service quality initiated by Parasuraman, Zeithaml and Berry (servqual) to assess the quality of academic services affecting student satisfaction. Once the determinants are known, they can be used by policy makers to improve student satisfaction levels. After identifying the determinant factors, policy makers can use them to improve the level of satisfaction of students. There are 100 respondents who participated in this research. The data was collected using surveys and analyzed using structural equation modeling with Smart PLS 3.0. The results showed that among five hypotheses tested, all variables have the positive influence, however, there are two latent variables which have significant associations, while the others have not. Responsiveness and empathy have positive and significant impact on the student satisfaction, while tangible, reliability and assurance have a positive impact but not significant. Keywords: customs student satisfaction, service quality, servqual, SEM.ABSTRAK:Meningkatkan kualitas pendidikan menjadi sangat penting dewasa ini untuk memenuhi tuntutan kebutuhan unit pengguna yang semakin meningkat. Penelitian ini mengadopsi lima dimensi kualitas jasa yang digagas oleh Parasuraman, Zeithaml dan Berry (Servqual) untuk menilai kualitas layanan akademik yang mempengaruhi kepuasan mahasiswa. Setelah faktor-faktor penentu dari dimensi servqual dapat diketahui maka faktor-faktor tersebut dapat digunakan oleh pembuat kebijakan untuk meningkatkan tingkat kualitas layanan kepada mahasiswa. Ada 100 responden di pilih secara acak dari total populasi yang berpartisipasi dalam penelitian ini. Data dikumpulkan dengan menggunakan survei online dan dianalisis dengan pemodelan persamaan struktural dengan bantuan software Smart PLS 3.0. Hasil penelitian ini menunjukkan bahwa dari kelima dimensi servqual, semua variabel memiliki pengaruh positif terhadap kepuasan mahasiswa, namun dari lima variabel tersebut hanya dua variabel laten yang mempunyai pengaruh signifikan, sementara tiga variabel yang lain tidak signifikan. Daya tanggap dan empati berpengaruh positif dan signifikan terhadap kepuasan siswa, sedangkan bukti fisik, keandalan dan jaminan memiliki dampak positif namun tidak signifikan.Kata Kunci: kepuasan, Mahasiswa Bea dan Cukai, kualitas layanan, Servqual, SEM

Abstract Two hundred and fifty thousand older adults die annually in United States hospitals because of iatrogenic conditions (ICs). Clinicians, aging experts, patient advocates and federal policy makers agree that there is a need to enhance the safety of hospitalized older adults through improved identification and prevention of ICs. To this end, we are building a research program with the goal of enhancing the safety of hospitalized older adults by reducing ICs through an effective learning health system. Leveraging unique electronic data and healthcare system and human resources at the University of Florida, we are applying a state-of-the-art practice-based data science approach to identify risk factors of ICs (e.g., falls) from structured (i.e., nursing, clinical, administrative) and unstructured or text (i.e., registered nurse’s progress notes) data. Our interdisciplinary academic-clinical partnership includes scientific and clinical experts in patient safety, care quality, health outcomes, nursing and health informatics, natural language processing, data science, aging, standardized terminology, clinical decision support, statistics, machine learning, and hospital operations. Results to date have uncovered previously unknown fall risk factors within nursing (i.e., physical therapy initiation), clinical (i.e., number of fall risk increasing drugs, hemoglobin level), and administrative (i.e., Charlson Comorbidity Index, nurse skill mix, and registered nurse staffing ratio) structured data as well as patient cognitive, environmental, workflow, and communication factors in text data. The application of data science methods (i.e., machine learning and text-mining) and findings from this research will be used to develop text-mining pipelines to support sustained data-driven interdisciplinary aging studies to reduce ICs.

The best companies compete with people analytics. They maximize the business value of their people to gain competitive advantage. This article proposes a network data science approach to people analytics. Using data from a software development organization, the article models developer contributions to project repositories as a bipartite weighted graph. This graph is projected into a weighted one-mode developer network to model collaboration. Techniques applied include centrality metrics, power-law estimation, community detection, and complex network dynamics. Among other results, the authors validate the existence of power-law relationships on project sizes (number of developers). As a methodological contribution, the article demonstrates how network data science can be used to derive a broad spectrum of insights about employee effort and collaboration in organizations. The authors discuss implications for managers and future research directions.
