BackgroundResearch on the comorbidity between cigarette smoking and major depression has not elucidated the pathways by which smoking is associated with depression.AimsTo examine the causal relationships between smoking and depression via fixed-effects regression and structural equation modelling.MethodData were gathered on nicotine-dependence symptoms and depressive symptoms in early adulthood using a birth cohort of over 1000 individuals.ResultsAdjustment for confounding factors revealed persistent significant (P<0.05) associations between nicotine-dependence symptoms and depressive symptoms. Structural equation modelling suggested that the best-fitting causal model was one in which nicotine dependence led to increased risk of depression. The findings suggest that the comorbidity between smoking and depression arises from two routes; the first involving common or correlated risk factors and the second a direct path in which smoking increases the risk of depression.ConclusionsThis evidence is consistent with the conclusion that there is a cause and effect relationship between smoking and depression in which cigarette smoking increases the risk of symptoms of depression.

This study examined the relation of cigarette smoking, psychological symptoms (e.g., depressive symptoms, anxiety), physical activity, and body mass index (BMI) separately by sex. The sample consisted of 815 African Americans and Puerto Ricans (324 males, 491 females). The participants were originally 14 years of age, and were followed to 32 years of age, and gave information on smoking, depressive symptoms, anxiety, physical activity, and BMI. Structural equation modeling showed that for males cigarette smoking in mid/late adolescence was related to cigarette smoking in emerging adulthood and early adulthood. Finally, cigarette smoking in early adulthood was negatively related to BMI in adulthood only for male participants. For female participants, cigarette smoking in adolescence was related to psychological symptoms (e.g., depressive symptoms, anxiety) in emerging adulthood and early adulthood. Psychological symptoms in early adulthood predicted less physical activity in adulthood, which in turn, was related to BMI. With one exception, all of the standardized coefficients were statistically significant. Implications for preventive interventions are discussed.

ObjectiveTo investigate the role of socioeconomic status (SES) in chronic non-communicable diseases (NCDs) and offer theoretical evidence for the prevention and control of NCDs.DesignCross-sectional survey and structural equation modelling.SettingNationwide, China.ParticipantsFemale participants in the 2008 National Health Services Survey in China who were 15 years and older.ResultsSES factors were associated with the increased risk of NCDs in Chinese women. Education was identified as the most important factor with a protective role (factor loading=−0.115) for NCDs. Income mainly affected NCDs directly, whereas occupation mainly affected NCDs indirectly. The effects of SES on NCDs were more significant than that of smoking. Medical insurance, smoking and self-reported health played a mediating role in the correlations between those SES factors and NCDs.ConclusionsIn China, socioeconomic disparities associated with the prevalence of NCDs exist among women. Educational and social interventions are needed to mitigate their negative consequences on health outcomes in Chinese women.

Tujuan pokok penelitian ini adalah untuk memperoleh bukti empirik mengenai pembentukan organisasi cerdas pada lembaga pendidikan tinggi. Paradigma baru organisasi adalah keharusan untuk menyesuaikan dengan lingkungan sehingga memerlukan perubahan melalui kepemimpinan dan demokratisasi. Lebih jauh, kita ingin melihat bagaimana pengaruh organisasi cerdas terhadap sikap profesional dosen.Penelitian ini dilaksanakan dengan menggunakan metode survei penjelasan pada Perguruan Tinggi Swasta di D KI Jakarta. Data yang dikumpulkan terdiri dari data sekunder yaitu melalui penyebaran kuesioner. Teknik Analisis data menggunakan  Structural Equation Modelling (SEM) dengan pendekatan Path Analysis (Analisis Jalur).Berdasarkan analisis dan pembahasan hasil penelitian ini, maka dapat disimpulkan beberapa hal sebagai berikut: (1) Tanggung jawab pimpinan memiliki pengaruh yang sangat signifikan terhadap organisasi cerdas, (2) Iklim demokrasi memiliki pengaruh yang signifikan terhadap organisasi cerdas, (3) Tanggung jawab pimpinan tidak memiliki pengaruh yang signifikan terhadap Iklim demokrasi, dan (4) Organisasi cerdas memiliki pengaruh yang signifikan terhadap sikap profesional.

Salah satu fungsi utama dari perpustakaan adalah pengemasan dan penyebaran informasi, bukanlah penciptaan informasi. Sehingga perpustakaan dituntut untuk memberikan layanan informasi yang lebih baik dan tepat guna. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh kualitas pelayanan terhadap kepuasan dan loyalitas serta pengaruh dari kepuasan terhadap loyalitas pengunjung di perpustakaan Daerah Kabupaten Sumenep. Sampel yang diteliti sebanyak 200 orang yang terdiri dari Siswa, Mahasiswa dan Umum. Data dianalisis dengan menggunakan analisis structural equation modelling (SEM). Berdasarkan hasil analisis dapat disimpulkan bahwa semakin baik kualitas pelayanan, maka semakin meningkat kepuasan pengunjung serta pengunjung akan semakin royal terhadap perpustakaan Daerah Kabupaten Sumenep. Key Word :      Perpustakaan, Structural Equation Modelling (SEM), Kualitas Pelayanan, Kepuasan Dan Loyalitas
