Effectiveness of Diagrammatic Guide Signs at Complex Interchanges

The present work investigated if drivers’ interpretation of diagrammatic arrow signs dropped in accuracy as the number of lanes at an interchange increased. A set of diagrammatic arrow signs were shown to 183 participants as part of a slideshow. Participants were prompted with a navigation objective, briefly shown a picture of a diagrammatic arrow sign that communicated the necessary information for navigation, then they were asked to make a navigation decision. The three factors considered were 1) the total number of lanes on the roadway, 2) the parity of lanes included in each of two branches on the sign, and 3) the difficulty of the navigation task decision. When positioned in an edge lane (easy condition), drivers were good at determining where their lane would lead. When positioned in a center lane (hard condition), their navigation performance improved with an odd number of lanes.

Specific Treatment of Elderly Pilgrims on Hajj According to the Hadith ; The Approach of Mukhtalif Ahadis

Most of Indonesian hajj pilgrims are elderly due to approximately 23 years waiting period. This paper aims to elaborate specific treatment of elderly pilgrims according to the hadith. Some hadith imply indirect prohibition to perform hajj by themselves while others still motivate the hajj in a hard condition. Using the approach of mukhtalif ahâdits, this paper seeks to answer three questions. First, how did hadith say about specific treatment of elderly hajj pilgrims. Second, how to deal with two groups of hadith which slightly look different. Third, how is proper contextual interpretation on the hadith in Indonesian contemporary life. The data compilation is through literature reviews and interviews. Then, the two groups of hadith are compromised using a method called al-jam’u wa al-tawfiq. It truns out that the first hadith applies for those who can’t really perform the hajj while another is for those with physical problems but could still stand for hajj using some facilities and policies. Those all lead to an inevitable need for a special hajj manasik for elderly so they could perform the hajj with better preparation. (Dengan waktu tunggu keberangkatan kurang lebih 23 tahun, sebagian besar jama’ah haji Indonesia adalah lansia. Penelitian ini mendiskusikan pandangan hadist soal perlakuan khusus terhadap jama’ah lansia. Beberapa hadist menyiratkan imbauan untuk tidak melaksanakan haji secara langsung, sedang beberapa lain tetap memotivasi pelaksanaan haji dalam keadaan sulit sekalipun. Dengan pendekatan mukhtalif ahâdits, penelitian ini fokus menjawab tiga persoalan. Pertama, bagaimana pandangan hadist terhadap jamaah lansia. Kedua, bagaimana mengompromikan dua (kelompok) hadist yang sekilas tampak berbeda. Ketiga, bagaimana interpretasi kontekstual hadist-hadist tersebut dalam konteks Indonesia dewasa ini. Data penelitian didapat melalui penelusuran pustaka dan wawancara. Dua kelompok hadist kemudian dikompromikan dengan metode al-jam’u wa al-tawfiq. Hasilnya menunjukkan bahwa hadist pertama berlaku bagi jama’ah yang benar-benar tidak bisa melaksanakan haji, sedang yang kedua adalah bagi mereka dengan kemampuan fisik yang minim namun masih memanfaatkan fasilitas dan kebijakan yang ada. Dari situ, adanya sebuah manasik (kelas haji) khusus lansia di Indonesia menjadi keniscayaan agar jama’ah lansia dapat semakin maksimal memersiapkan dan melaksanakan haji)

Person-Focused Effort Praise: "Hard Worker" Has Negative Effects for Adults After a Failure

Although work with children demonstrates a benefit of process-focused praise relative to person-focused praise on post-failure motivation, few studies have examined this result in adults. We tested the effect of three types of praise on adults’ post-failure outcomes: person-focused intelligence (“high intelligence”), person-focused effort (“hard worker”), and process-focused effort (“worked hard”) in a sample of 156 adults recruited from Amazon’s MTurk. Participants completed a set of easy visual pattern recognition problems and were told that they performed better than most adults and were given one of the three types of feedback. They then completed more difficult problems and were told that they had not performed well. Participants in the “hard worker” condition (compared to “worked hard”) were more likely to endorse intelligence as a reason for failure. They also reported lower perceived success and less enjoyment than participants in other conditions. Participants in the “high intelligence” condition were more likely to attribute their failure to intelligence than participants in the “worked hard” condition. The results suggest that the benefit of process-focused praise typically found in children (worked hard compared to intelligent) was mostly not replicated in adults, and person-focused effort praise was detrimental in a non-college student adult sample.

Design and Implement of a Computer Forensics Model for Cloud Environments

With the maturing and wide application of cloud computing technology, there are more and more crimes in the environment of cloud computing, effective investigation of evidence against these crimes are extremely important and urgent. Because it features the characteristics of computing environment of virtual, mass storage, distribution of data, multi-tenant and so on, the cloud calculating sets an extremely hard condition for investigation of evidence. For this purpose, this paper presents a reference evidential model for cloud computing environments, and it also discusses the implement to the four aspects of computer evidence.
