A Multi-Attribute Attitude Model for the Prediction of University Preference

PurposeIn this research paper, an adaptive output-feedback robust active disturbance rejection control (RADRC) is designed for the multiple input multiple output (MIMO) quadrotor attitude model subject to unwanted uncertainties and disturbances (UUDs).Design/methodology/approachIn order to achieve the desired control objectives in the presence of UUDs, the low pass filter (LPF) and extended high gain observer (EHGO) methods are used for the estimation of matched and mismatched UUDs, respectively. Furthermore, for solving the chattering incurred in the standard sliding mode control (SMC), a multilayer sliding mode surface is constructed. For formulating the adaptive output-feedback RADRC algorithm, the EHGO, LPF and SMC schemes are combined using the separation principle.FindingsThe findings of this research work include the design of an adaptive output-feedback RADRC with the ability to negate the UUDs as well as estimate the unknown states of the quadrotor attitude model. In addition, the chattering problem is addressed by designing a modified SMC scheme based on the multilayer sliding mode surface obtained by utilizing the estimated state variables. This sliding mode surface is also used to obtain the adaptive criteria for the switching design gain parameters involved in the SMC. Moreover, the requirement of high design gain parameters in the EHGO is solved by combining it with the LPF.Originality/valueDesigning the flight control techniques while assuming that the state variables are available is a common practice. In addition, to obtain robustness, the SMC technique is widely used. However, in practice, the state variables might not be available due to unknown parameters and uncertainties, as well as the chattering due to SMC reduces the performances of the actuators. Hence, in this paper, an adaptive output-feedback RADRC technique is designed to solve the problems of UUDs and chattering.

Persistent Negative Symptoms

Background Negative symptoms are an important unmet treatment need for schizophrenia. This study is a preliminary, open, single-arm trial of a novel hybrid intervention called mobile-assisted cognitive behavioral therapy for negative symptoms (mCBTn). Objective The primary aim was to test whether mCBTn was feasible and could reduce severity of the target mechanism, defeatist performance attitudes, which are associated with experiential negative symptoms and poor functioning in schizophrenia. Methods Participants with schizophrenia or schizoaffective disorder (N=31) who met prospective criteria for persistent negative symptoms were enrolled. The blended intervention combines weekly in-person group therapy with a smartphone app called CBT2go. The app extended therapy group skills, including recovery goal setting, thought challenging, scheduling of pleasurable activities and social interactions, and pleasure-savoring interventions to modify defeatist attitudes and improve experiential negative symptoms. Results Retention was excellent (87% at 18 weeks), and severity of defeatist attitudes and experiential negative symptoms declined significantly in the mCBTn intervention with large effect sizes. Conclusions The findings suggest that mCBTn is a feasible and potentially effective treatment for experiential negative symptoms, if confirmed in a larger randomized controlled trial. The findings also provide support for the defeatist attitude model of experiential negative symptoms and suggest that blended technology-supported interventions such as mCBTn can strengthen and shorten intensive psychosocial interventions for schizophrenia.

Attitude Model

The study examined the moderating effect of personality variable of excellence on the predictive effectiveness of multi-attribute attitude model. Data were collected from Master's students in business administration at four Canadian universities. Analysis indicated that the students who scored high on excellence showed a stronger correlation between attitude and intention to enter a program than the students who scored low. It was speculated that excellence has potential as a segmentation variable for complex, high involvement products.

Penelitian ini bertujuan untuk menganalisis pengaruh untuk untuk mengetahui dan menganalisa sikap konsumen terhadap brand clothing lokal Lombok. Jenis penelitian ini adalah kuantitatif yang bersifat deskriptif.. Populasi pada penelitian ini adalah Konsumen brand clothing lokal Lombok di wlayah Kota Mataram. Jumlah sampel sebanyak 100 orang. Teknik pengumpulan data dilakukan menggunakan angket, dokumentasi, dan wawancara, sedangkan alat pengumpulan data menggunakan kuesioner. Alat analisis yang dugunakan adalah Fishbein Attitude Model . Hasil penelitian menunjukkan bahwa:1. Tanggapan atau sikap konsumen di Kota Mataram terhadap atribut desain, merek, kualitas, dan model brand clothing lokal Lombok sangat baik atau positif.2. Setelah dilakukan uji analisa sikap konsumen terhadap brand clothing lokal Lombok, responden menganggap hal yang paling dipertimbangkan pertama kali dalam melakukan pembelian produk brand clothing lokal Lombok adalah Desain, kemudian penilaian selanjutnya adalah Merek, Kualita, dan yang paling terakhir adalah Model dari produk itu sendiri.3. Pada saat konsumen melakukan evaluasi setelah melakukan pembelian, atribut Merek, Kualitas, dan Model mengalami kenaikan positif. Akan tetapi pada atribut Desain mengalami sedikit penurunan setelah konsumen melakukan evaluasi, hal ini menunjukkan walaupun atribut Desain memiliki nilai paling tinggi diantara atribut yang lain namun masih mengalami sedikit penurunan setelah konsumen evaluasi pembelian produk

Attitude Model

The high usage of multimedia content in daily activities has put strains on the network operators as the transmitted content can lead to network congestion. In an effort to control and reduce the traffic, network operators have capped their billing plans. A capped billing plan may require the user to pay extra money when exceeding the quota, and this can result in undesirably high bills for the mobile users. A solution that has been shown to reduce the size of transmitted data and also addresses user needs in terms of billing cost was presented in Molnar and Muntean (2013a). This solution involves personalising the multimedia content based on the user attitude towards risk. It makes use of a model that assesses the user attitude towards risk by considering the user age, gender, and risk attitude self-assessment. The research presented in this chapter adds to the state of the art by presenting an improvement to the user risk attitude model (Molnar & Muntean, 2012) that takes into account the user context (e.g. whether the user uses the roaming service or not, the current data consumption) as well as the user input. The improved model may be used to provide a more accurate trade-off: quality vs. price (Molnar & Muntean, 2013a) and this leads to an increase in user satisfaction and better service quality.

Attitude Model

The authors compare the relative effectiveness of comparative/noncomparative and product-based/non-product-based advertising in the implementation of an associative strategy for cognitive brand positioning. Two metaconstructs, cognitive accuracy and cognitive clarity, are defined, each within an attitude model and a probabilistic multidimensional scaling model. The results from these very different methodological and conceptual approaches indicate that direct comparative advertisements are superior in engendering overall brand positioning, whereas only product-based direct comparative ads are superior in engendering brand positioning at the attribute level, and only in terms of positioning clarity.
