Dampak respon emosi terhadap kecenderungan perilaku pembelian impulsif konsumen online dengan sumberdaya yang dikeluakan dan orientasi belanja sebagai variabel mediasi

Abstract: This research has an aim of examining the influence of emotional responses towards the impulsive buying behavior tendency from the online consumers, as a result of direct advertisement's stimulus. Online Stimulus advertisement is formatted through a kind of audio-visual media format, picture animation, and picture text. The main purpose of this research is focused on the format shape of online medium, however, as a compare, brochures are usually used as one of offline mediums. The format of research use factorial experimental design with the online and offline medium as the factor. Besides, to evaluate indirect impacts of emotional response to the impulsive buying behavior tendency, it has used resources expenditure, recreation and convenience shopping oriented which are intervening variables. The results of this research shows that there are different of stimulus impacts between offline and online medium formats. It has been found that the format of online medium has stronger stimulus effect than the offline one. Although, online format medium has stronger stimulus total effect, but still the format of audio visual medium and text of picture has stronger effect than the form of picture animation. The other finding, The resources expenditures has a positive intervening between emotional responses towards recreation shopping oriented but has negative intervening towards convenience shopping oriented. This can be clearly seen on the format of audio visual and picture animation medium. The result of the same analysis has proven that convenience shopping oriented is a positive intervening between emotional response and impulsive buying behavior tendency but recreation shopping oriented has negative impact.

The granger causality tests for the five asean countries stock markets and macroeconomic variables during and post the 1997 asian financial crisis

Abstract: This study seeks to examine the existence of Granger-causality among stock prices indices and macroeconomic variables in five ASEAN countries, Indonesia; Malaysia; the Philippines; Singapore; and Thailand with particular attention to the 1997 Asian financial crisis and period onwards. Using monthly time series data of the countries, a Granger-causality test based on the vector autoregressive (VAR) analytical framework was employed to empirically reveal the causality among the variables. This research finds that there were few Granger causalities found between the country's wtock price index and macroeconomic variables. This indicates that the linkages between domestic stock price movements and macroeconomic factors were very. Due to that, the ASEAN stock markets were crelatively unable to efficiently capture changes in economic fundamentals during the observation period in most of the countries in accordance to the literature in emerging stock markets, and that the influence of specific macroeconomic factors on the domestic economies differ across countries. This also implies that the stock markets do not seem to have played a significant role in most countries' economies, and macroeconomic variables are unlikely to be appropriate indicators to predict not only the future behaviour of other macroeconomic variables, but also that of the stock market price indices. Abstract in Bahasa Indonesia : Makalah ini mencoba untuk menganalisis keberadaan Granger-causality antara indeks harga saham dan variabel-variabel ekonomi makro di lima negara ASEAN, yaitu Indonesia; Malaysia; Filipina; Singapore; dan Thailand yang berfokus pada periode terjadinya krisis keuangan Asia pada tahun 1997 dan sesudahnya. Dengan mempergunakan data time series bulanan dari setiap negara tersebut, tes Granger-causality yang didasarkan pada kerangka analisa VAR (vector autoregressive) diaplikasikan untuk mengungkap secara empiris hubungan kausal antar variabel. Dari hasil tes diketahui bahwa hanya terdapat sejumlah kecil Granger-causality antara indeks harga saham dan variabel-variabel ekonomi makro. Hal ini mengindikasikan sangat lemahnya kaitan antara pergerakan indeks harga saham di dalam negeri dengan variabel-variabel ekonomi makro dikarenakan bahwa pasar modal di negara-negara ASEAN relatif tidak mampu secara efisien menangkap informasi perubahan besaran-besaran ekonomi makro domestik. Dan, bahwa pengaruh dari variabel-variabel ekonomi makro tertentu dalam perekonomian domestik ternyata berbeda di tiap negara. Hal tersebut mengimplikasikan bahwa bursa saham ASEAN nampaknya tidak berperan penting dalam perekonomian domestik, dan bahwa variabel-variabel ekonomi makro negara-negara tersebut nampaknya tidak dapat dipakai sebagai indikator yang baik untuk memprediksikan bukan saja terhadap perilaku variabel-variabel ekonomi makro lainnya, tetapi juga perilaku indeks harga saham di masa yang akan datang. Kata kunci: Granger-causality, krisis keuangan Asia, bursa saham, variable ekonomi makro, VAR.

Behaviors Coordination and Learning on Autonomous Navigation of Physical Robot

Abstract: Behaviors coordination is one of keypoints in behavior based robotics. Subsumption architecture and motor schema are example of their methods. In order to study their characteristics, experiments in physical robot are needed to be done. It can be concluded from experiment result that the first method gives quick, robust but non smooth response . Meanwhile the latter gives slower but smoother response and it is tending to reach target faster. Learning behavior improve robot’s performance in handling uncertainty. Q learning is popular reinforcement learning method that has been used in robot learning because it is simple, convergent and off policy. The learning rate of Q affects robot’s performance in learning phase. Q learning algorithm is implemented in subsumption architecture of physical robot. As the result, robot succeeds to do autonomous navigation task although it has some limitations in relation with sensor placement and characteristic.
