When a solid (filled-in) triangle is mirror-reflected about its vertex such that one angle arm and its reflection form a straight edge, this straight edge appears as a chevron bent in the direction of the other sides of the triangles, an effect directionally opposite to the well-known tilt illusion that occurs with outline angles. It has been proposed that these negative solid-angle illusions (assimilation effects) which occur in dual-angle (Bourdon-type) displays result from a failure to discriminate between the test (judged) edges and the bisectors of the solid angles. In dual-angle outline displays, near-zero effects have been attributed to the availability of collinearity cues. These hypotheses were tested in two experiments in which cues to collinearity were reduced by inserting gaps between the angles and in which collinearity information was increased by adding thick ‘necks’ to the displays. The results are consistent with predictions and implicate not only the nature of the angle display, but also the way in which observers perform the matching task in the production of assimilation effects.

Alignment Errors

The tilt illusion (TI) was investigated by using both short (19 min) and long (2 deg 6 min) test lines, at three angles of test line-inducing line separation (15°, 45°, and 75°). Three groups of ten observers each provided data under one of three task conditions: vertical judgment, parallel matching, and dot alignment on a common visual display. The main result was that both the vertical judgment and the parallel matching task provided similar, classic TI angular functions with the means ordered 15° > 45° > 75° and with small attraction effects at 75° in three of the four relevant functions. The third task, dot alignment, yielded results different from the average of the other two: no attraction effects occurred and, with the short test line, the obtained mean illusion at 45° exceeded those at the other intersect angles. These results are consistent with alignment data reported by others. One explanation is that the inducing line produces an apparent bowing of the test line which would be reflected in dot alignments but not in vertical setting or in parallel matching. However, direct evidence does not support this hypothesis. An alternate hypothesis, for which independent evidence exists, is that alignment errors reflect perceptual mistracking but that the origin of these errors is not at the tip of the test line but within it. Although this does not explain dot alignment errors, it highlights their complexity and the need to interpret them with caution.

Information associated with the self is preferentially processed compared to others. However, cultural differences appear to exist in the way information is processed about those close to us like our mothers. In eastern compared to western cultures, information about mother seems to be processed as well as our self. However, it is not clear whether this lack of difference is due to familiarity or would extend to processing arbitrary perceptual information associated with different categorical labels. The current study employs a perceptual association paradigm in which category labels like self, mother and none are associated with arbitrary shapes to study self vs mother processing in an Indian sample. We hypothesized that there would be no difference between self and mother processing given the familial and collectivistic tendencies in India. Participants performed a matching task between shape and a pre-assigned category label, with self, mother, and none as categories in Experiment 1A and self, friend, and none as categories in Experiment 1B. Analysis of RT, accuracies and signal detection theoretic measures showed that information about mother is processed as well as self in Experiment 1A, but this effect is not present with friend in Experiment 1B. Moreover, participants’ processing for the self-associated information gets attenuated depending upon the other close person category used in the task (friend vs mother) indicating that self-information processing is dynamically dependent on the categorical contexts in which such processing takes place. Our findings have implications for understanding the processing of self-associated information across cultures and contexts.

This aims to review and analyze the Jordanian experiment in the developmental regional planning field within the decentralized managerial methods, which is considered one of the primary basic provisions for applying and success of this kind of planning. The study shoed that Jordan has passed important steps in the way for implanting the decentralized administration, but these steps are still not enough to established the effective and active regional planning. The study reveled that there are many problems facing the decentralized regional planning in Jordan, despite of the clear goals that this planning is trying to achieve. These problems have resulted from the existing relationship between the decentralized administration process’ dimensions from one side, and between its levels which ranged from weak to medium decentralization from the other side, In spite of the official trends aiming at applying more of the decentralized administrative policies, still high portion of these procedures are theoretical, did not yet find a way to reality. Because any progress or success at the level of applying the decentralized administrative policies doubtless means greater effectiveness and influence on the development regional planning in life of the residents in the kingdom’s different regions. So, it is important to go a head in applying more steps and decentralized administrative procedures, gradually and continuously to guarantee the control over any negative effects that might result from Appling this kind of systems.   © 2018 JASET, International Scholars and Researchers Association

The situation that has developed in the International System of Units (SI) as a result of adopting the recommendation of the International Committee of Weights and Measures (CIPM) in 1980, which proposed to consider plane and solid angles as dimensionless derived quantities, is analyzed. It is shown that the basis for such a solution was a misunderstanding of the mathematical formula relating the arc length of a circle with its radius and corresponding central angle, as well as of the expansions of trigonometric functions in series. From the analysis presented in the article, it follows that a plane angle does not depend on any of the SI quantities and should be assigned to the base quantities, and its unit, the radian, should be added to the base SI units. A solid angle, in this case, turns out to be a derived quantity of a plane angle. Its unit, the steradian, is a coherent derived unit equal to the square radian.

The objectives of the research were to describe the types of speech acts used in televised political debates of governor candidates of North Sumatera, to derive the dominant type of speech acts used in televised political debates of governor candidates of North Sumatera and to elaborate the way of five governor candidates of North Sumatera use speech acts in televised political debates. This research was conducted by applying descriptive qualitative research. The findings show that there were only four types of speech acts used in televised political debates, Debat Pemilukada Sumatera Utara and Uji Publik Cagub dan Cawagub Sumatera Utara, they were assertives, directives, commissives and expressives. The dominant type of speech acts used in both televised political debates was assertives, with 82 utterances or 51.6% in Debat Pemilukada Sumatera Utara and 36 utterances or 41.37% in Uji Publik Cagub dan Cawagub Sumatera Utara. The way of governor candidates of North Sumatera used speech acts in televised political debates is in direct speech acts, they spoke straight to the point and clearly in order to make the other candidates and audiences understand their utterances.   Keywords: Governor Candidate; Political Debate; Speech Acts

The cultural environment of Ibn al-Arabi is in Andalusia, Spain today. There, on the one hand, Sufism, on the other hand, thinks like Ibn Bacce (Death.1138), Ibn Tufeyl (Death186), Ibn Rushd (Death.1198) and the knowledge and philosophy inherited by scholars, . Ibn al-Arabi (1165-1240), that was the effect of all this; But more mystic (mystic) circles came out of the way. This work, written by Ibn al-Arabi's works (especially Futuhati Mekkiye), also contains a very small number of other relevant sources.

This chapter considers Freedman’s contribution to scholarship and the nascent elements of a school of thought relevant to both academic and policy realms, as well as introducing a more skeptical and critical approach to the subject’s scholarship. It considers Freedman’s engagement with the policy world and why this has managed to be both extensive and successful, as well as its outcomes. It also introduces discussion of possible challenges to Freedman’s work, presenting a balancing perspective to positive appreciations of his oeuvre. The chapter concludes by indicating the weaknesses of such challenges and reaffirms the sense of a school of thought informed by a distinctive approach. This is the blend of scripturalism and constructivism, on one side, with realism, on the other, that is the hallmark of the nascent school, and the way in which it is germane in both academic and policy domains.

This chapter spans Freedman’s earliest focus on nuclear weapons and his development of strategic scripts as an analytical tool over three decades later. It discusses the way in which opposing logics of disarmament and armament co-existed in relation to nuclear weapons. It deploys the notion of strategic scripts to explain the contradictions inherent in approaches to nuclear disarmament, developing the concept of strategic scripts as it does so. The notion of scripts can be used to explore and even to promote nuclear disarmament. Two scripts, one of ‘stable reduction’, the other of ‘disarmament’, each serve to frame thinking. These scripts and the interactions they generate facilitate understanding of the way in which opposite instinctive reactions and, stemming from these, scripts about nuclear weapons co-exist, but are fragile as either an analytical or a strategic tool.

The Introduction describes the way in which the volume originated and briefly surveys the chapters contained in it. Four chapters (by Joseph Witztum, Patricia Crone, Gerald Hawting, and Michael Cook) originate from papers delivered at the conference ‘Islam and its Past: Jahiliyya and Late Antiquity in the Qurʾan and Tradition’. The other four chapters (by Devin Stewart, Nicolai Sinai, Angelika Neuwirth, and Iwona Gajda) were not presented at this conference. All the chapters are concerned directly or indirectly with Islamic revelation, and for the most part with the Qurʾan. We live in a time when the study of the Qurʾan has been making a remarkable comeback after spending a generation on the backburner. This volume will give the interested reader a broad survey of what has been happening in the field and concrete illustrations of some of the more innovative lines of research that have recently been pursued.

This chapter models the relation between temporal aspect (run for an hour vs. *run all the way to the store for an hour) and spatial aspect (meander for a mile vs. *end for a mile) previously discussed by Gawron (2009). The chapter shows that for-adverbials impose analogous conditions on the spatial domain and on the temporal domain, and that an event may satisfy stratified reference with respect to one of the domains without satisfying it with respect to the other one as well. This provides the means to extend the telic-atelic opposition to the spatial domain. The chapter argues in some detail that stratified reference is in this respect empirically superior to an alternative view of telicity based on divisive reference (Krifka 1998).
