Abstract:

This study observed Brahman cross steer carcass production, (slaughter weight, carcass weight, and dressing percentage). The material used was 166 heads of white Brahman cross steer, with an average slaughter weight of 424.40–35.86 kg, and the range of age was 1.5–2 years. Sample of this study was Brahman cross steers with 83 heads large framed and 83 heads medium framed. The study method used was case studies. The obtained data was analyzed with independent t-tests, simple linear regression, and correlation. Results showed that frame size was highly significant (P<0.01) in slaughterweight. The average slaughterweight on the medium frame was 415.82 ± 35.98 kg, and the medium frame was 432.98 ± 33.83 kg. Frame size is also highly significant (P<0.05) in carcass weight. The correlation between slaughter weight and carcass weight was very close, with a correlation coefficient of 0.87 on medium frames and 0.90 on large frames. This study concluded that Brahman cross steers with large frames resulted in slaughter weight and carcass weight higher than medium frames but produced the same carcass percentage.

Abstract:

Fatwa discourse is among the most effective and powerful instrumental discourse in Muslim communities as a source of knowledge, guidance, adaptation and change. Thus, this study aimed at investigating the discourse of fatwas on the ruling of learning and speaking English to reveal the role such fatwas have played in shaping the attitude towards the English language among Muslims. In doing so, the data, which comprised English and Arabic fatwas, were analysed utilising frame analysis to understand how the issue was framed. The results showed two main ideological overarching frames: an anti-English frame and a pro-English frame. The anti-English frame, which serves as a form of resistance/rejection, shaped English through the following sub-frames: necessity, unArabic, unIslamic, anti-imitation and consequence/ramification. On the other hand, the pro-English frame, which is a form of acceptance, ideated English through the frames of necessity and permissibility.

Abstract:

AbstractWe examine a Query Theory account of risky choice framing effects — when risky choices are framed as a gain, people are generally risky averse but, when an equivalent choice is framed as a loss, people are risk seeking. Consistent with Query Theory, frames affected the structure of participants’ arguments: gain frame participants listed arguments favoring the certain option earlier and more often than loss frame participants. These argumentative shifts mediated framing effects; manipulating participants initial arguments attenuated them. While emotions, as measured by PANAS, were related to frames but not related to choices, an exploratory text analysis of the affective valence of arguments was related to both. Compared to loss-frame participants, gain-frame participants expressed more positive sentiment towards the certain option than the risky option. This relative-sentiment index predicted choices by itself but not when included with structure of arguments. Further, manipulated initial arguments did not significantly affect participant’s relative sentiment. Prior to changing choices, risky choice frames alter both the structure and emotional valence of participants’ internal arguments.

Abstract:

This paper discusses the effects a severe fire had on a steel high-rise frame. The damage to this frame was no worse than in other fire-damaged steel-framed buildings such as the Alexis Nihon hotel in Montreal and the Broadgate in London. The yield strengths of the columns were not significantly decreased. There were locked-in residual moments and forces. However pushover analyses of simple frames with and without residual moments show that the stability and lateral load carrying capacity of the frames were unaffected by residual moments, as would be expected from the principles of plastic analysis. The steel frame and floor system of this building could have been reinstated relatively quickly, as has been done in comparable fire-damaged steel-framed high-rises.

Abstract:

Purpose The purposes of two experiments were to examine how brands may create a broad brand impression and benefit brand extensions by crafting logo frames. Design/methodology/approach Two experimental studies were conducted. Study 1 examines how removing and breaking logo frames expands perceived brand breadth. Study 2 considers the implication of this logo frame effect and indicates the impact of logo frames on brand extension scenarios. Findings Removing and breaking logo frames could expand perceived brand breadth and, in turn, benefits the brand extensions, especially for promotion-focused consumers. However, prevention-focused people held favorable brand extension attitudes when the brand logo constructs a complete frame due to its perceived trustworthiness. Research limitations/implications As an initial exploration, this study conceptualizes and manipulates logo frames as full framed, partial framed and open logo. Future research studies could include further design features in the examination. Practical implications If a brand seeks to be broad, removing or breaking its logo frame is an alternative. However, consequential negative impressions on brand extension attitudes among prevention-focused customers should be considered. Originality/value This study is the first investigation into the impacts of logo frame patterns on consumers’ perception of brand breadth and the consequent extension attitudes.

Abstract:

There is limited knowledge about how crises are framed on different social media platforms specifically in a non-Western cultural context. This study compares how extreme environmental crises—Hurricane Maria and haze—were framed on Twitter and Weibo. Through word-cloud, co-occurrence, and thematic analyses with Hurricane Maria-related tweets, this study identified two major frames of this crisis: a disaster frame and a political frame. Similarly, by analyzing haze-related posts on Sina Weibo, two major frames emerged: an environmental frame and a health frame. Both crises were largely framed as environmental issues rather than health risks or crises. Such framing helps shape the existence of Hurricane Maria and haze as legitimate facts. The findings also reveal that cultural variances, eg, power distance, collectivist-individualist culture, and uncertainty avoidance, impact crisis framing. This study indicates the importance of designing culture-fit messages and incorporating social media strategies in crisis communication while developing emergency management plans and adds knowledge to the limited literature on social-mediated crisis communication in different cultural contexts. Such knowledge will provide theoretical and practical implications for crisis scholars, emergency management practitioners, and policymakers.

Abstract:

In this study, we introduce framed clad helices, which are a generalization of clad (i.e. C-slant or 2-slant) helices in Euclidean 3-space. They also include framed helices and framed slant helices. After, we give a characterization of the framed clad helices using the alternative adapted frame, which is more useful than the adapted frame of a framed curve. Moreover, we prove the existence of framed spherical images of any framed curve using alternative adapted frames. Additionally, we obtain interesting results regarding the relationship between a framed clad helix and its framed spherical images. Finally, we support the concept with some nice graphics.

Abstract:

There is a growing tendency for policy makers to frame climate change action in terms of non-climate benefits, raising important empirical questions regarding the utility of such approaches. Across three studies we explore whether (and when) non-climate frames can lead to greater support for climate policy relative to climate frames. In Study 1 we framed a car-use reduction policy in relation to climate change or public health and showed that non-climate frames can stimulate greater support for climate policy. Study 2 explored frame relevance as a potential boundary condition to the efficacy of non-climate frames. Study 3 found that attempts to frame climate policy in relation to non-climate issues that affect participants personally can fail if that issue is not seen as being sufficiently relevant. We suggest that non-climate frames can be an effective tool in stimulating support for climate policy, however greater consideration of the key mechanisms is required.

Aiming at the problem of tag conflict in the RFID system, an improved algorithm based on dynamic framed slotted ALOHA algorithm is proposed. In this algorithm , when the recognition of a frame length is still not finished, according to the existing conflict timeslot and free timeslot inside of frame, frame length can adjusted in advance, furthermore a new frames recognition process is began, which can improve the recognition efficiency of the existing algorithm, increase throughput. The performance simulation experiment shows that the improved algorithm has more advantage than dynamic slotted ALOHA algorithm.

Abstract:

This study investigates how Burmese refugees were framed by Fort Wayne’s The Journal Gazette located in one of Indiana’s cities where refugee resettlement has taken place over the last two decades. We analyzed 335 stories and 286 accompanying images to identify salient textual and visual frames. Results show that the human interest and attribution of responsibility were most salient textual frames, while the visual frame of exotic was dominant. Feature stories were more likely to have a human interest frame and, if an image is included, to reflect the visual frame of Burmese as being exotic. As a global refugee crisis continues to unfold, this study presents implications for how media coverage of future refugees in the United States will evolve based on public opinion.

Abstract:

Reinforced concrete buildings with shearwalls are very efficient to resist earthquake disturbances. In general, reinforced concrete frames are governed by flexure and low-rise shearwalls are governed by shear. If a structure includes both frames and shearwalls, it is generally governed by shearwalls. However, the ductility of ordinary reinforced concrete framed shearwalls is very limited. The experiments on framed shearwalls made of corrugated steel was recently reported. It was found that the ductility of framed shearwalls can be greatly improved if the thickness of the corrugated steel wall is appropriate to the surrounding reinforced concrete frame. If the thickness of the corrugated steel wall is too large when compared to the surrounding frame, the ductility will be reduced. It is shown in this paper that the fiber-reinforced plastic composites can be used to strengthen the critical regions of the reinforced concrete frames, so that the seismic behavior (including ductility and energy dissipation capability) is greatly improved.

An explicit, simple characterization of those operators that arise as Weyl–Heisenberg frame operators on L2(ℝn) is obtained in terms of the concept of tile vertices of an operator. Generalizations of these frames to abstract Hilbert spaces are introduced and these and their frame operators are characterized in terms of Weyl–Heisenberg frames and frame operators in Euclidean spaces. Appropriate "window" versions of these concepts and results are also presented.

Abstract:

A new notion in frame theory has been introduced recently under the name woven-weaving frames by Bemrose et al. In the study of frames, some operators like analysis, synthesis, Gram and frame operators play the central role. In this paper, for the first time, we introduce and define these operators for woven-weaving frames and review some of their properties. In continuation, we investigate the effect of different types of operators on the woven frames and their bounds. Also, we provide some conditions that shows sum of woven frames are also woven frames. Finally, we apply these properties with an example.

Abstract:

This study explores the Samsung Galaxy Note 7 explosion crisis by analyzing posts on Twitter in three nations: the United States, Australia, and South Korea. Using the perspectives of generic frames, issue-specific frames, cross-national frames, and user sentiment on Twitter, this study analyzes 600 posts (200 from each nation). Results reveal that Twitter posts frequently framed the crisis using attribution, morality, and conflict frames. Posts about the explosion were more professional frame oriented than national frame oriented. Negative sentiment was dominant in Twitter posts about the explosion. Morality, corporate breakdown, and customer concerns were highly associated with negative sentiment. The results demonstrate how global users respond to a corporate crisis. Study implications and suggestions are discussed.

Abstract:

Masonry infilled walls are widely used in reinforced concrete (RC) frams worldwide. However, infilled RC frame building failure is a common mode in destructive earthquakes. Further researcher is needed to bring insightful understandings into the behaviors of these structures. Therefore, this study investigates seismic parameters, ultimate tensile damage, and force transfer mechanisms in a reinforced concrete structure under in-plan load. For this purpose, the definitions and the relevant literature were reviewed. Then, an analytical software supporting an infill model was selected and described altogether with a particular modeling approach. Calibrating software results with those presented by Abdulhafez et al. (2014), the researchers designed a series of planer one-story one-bay reinforced concrete frames upon ACI 318M-14 Building Code. The seismic behavior of infilled frames were also studied using finite element method. Force transfer mechanisms in infilled frame with opening, which is one of the important items, was investigated in this study. Comparing the analysis outcomes with the bar frame, it was indicated that the ultimate load, stiffness, and toughness of the full in-filled frame were increased while the ductility was decreased. It was also revealed that the presence of opening in infilled frame decreased the ultimate load, stiffness and toughness corresponding full infilled frame. In addition, the increasing of opening size increased the reduction of the ultimate load, stiffness and toughness.

Abstract:

Prefabricated panel-assembled wall systems, comprising a confining frame and infill lightweight panels of autoclaved aerated concrete (AAC), are widely employed in framed structures. Different from studies on a main frame with infill walls, this study aimed to explore the seismic performance of partition walls, which were fabricated with AAC panel-assembled walls and located outside of the main frames. Two full-scale specimens, one with a door opening and the other without, were constructed and cyclic loading tests were executed to examine the failure modes, hysteresis characteristics, envelope curves, ductility, strength and stiffness degradation, as well as energy dissipation capacity of the AAC panel-assembled walls. Additionally, a restoring-force model for the panel-assembled walls was developed and a method for predicting the lateral load-bearing capacity of the AAC panel-assembled walls was proposed. The findings indicated that the panels enhanced the system’s lateral resistance, energy dissipation capacity, and deformation capability. The door frame increased the initial stiffness, peak lateral load and energy dissipation capacity of the AAC panel-assembled wall compared to the wall without a door frame. Compared to the specimen without a door frame, the peak lateral load of the specimen with a door frame increased by 19.7–30.1%. The deformation capacity of the panel-assembled walls aligned with the requirements for concrete framed structures.

Abstract:

Weighted and controlled frames have been introduced recently to improve the numerical efficiency of iterative algorithms for inverting the frame operator. In this paper, we develop systematically these notions, including their mutual relationship. We will show that controlled frames are equivalent to standard frames and so this concept gives a generalized way to check the frame condition, while offering a numerical advantage in the sense of preconditioning. Next, we investigate weighted frames, in particular their relation to controlled frames. We consider the special case of semi-normalized weights, where the concepts of weighted frames and standard frames are interchangeable. We also make the connection with frame multipliers. Finally, we analyze weighted frames numerically. First, we investigate three possibilities for finding weights in order to tighten a given frame, i.e. decrease the frame bound ratio. Then, we examine Gabor frames and how well the canonical dual of a weighted frame is approximated by the inversely weighted dual frame.

Abstract:

Current structural design practices recognize that the maximum strength of frames and the maximum strength of component members are interdependent, but it is not practical to take this interdependence into account rigorously. This reasoning lends support to the Structural Stability Research Council (SSRC) technical memorandum which states that "in design practice, the two aspects, stability of individual members and elements of the structure and stability of the frame system as a whole, be considered independently." However, it is admitted that "difficulties are encountered in complex frameworks when attempting to compensate automatically in column design for the instability of the entire frame." Considerable attention has been paid in the literature to the study of different types of frame elements such as compression members, beams, bracing system and connections and also their effects on the stability of the frame and as a result, several methods have been proposed for evaluating the frame strength. However, the effective length concept for evaluating the frame strength is the most popular method for estimating the interaction effects of a framed member on the total frame stability, and it is recommended by almost all the current specifications.

Abstract:

The framing strategies of social movements are typically characterized by movement actors conceptually and rhetorically expanding frames. We contend that movement actors also contract frames by deliberately excluding frame elements. We add the concept of contraction to the frame-alignment construct and show how frame contraction allows for enhanced theorizing about the dialectical and dynamic nature of social movements. We describe three distinct frame contraction processes, frame removal, frame minimization, and frame restriction, which characterize common frame contraction strategies. We illustrate frame contraction by examining the framing approaches used by the United Auto Workers as they bargained with automakers across two rounds of negotiations in 1945–46 and 1949–1950. We show how frame contraction articulates undertheorized complexities in changes to social movement frames. We also illustrate potential blind spots, biases, or distortions that may arise absent the frame contraction construct.

Abstract:

Abstract This paper concerns notions of Booleanness in the setting of partial frames, which, in contrast to full frames, do not necessarily have all joins. Examples of these include bounded distributive lattices, σ- and κ-frames. We provide four distinct conditions which all reduce in the case of full frames to each element having a complement. These concepts depend heavily on the free frame over a partial frame, the congruence frame of a partial frame and the relations between them. We also examine the adjoint situation between the congruences of a partial frame and those of its free frame.

<abstract><p>Quaternionic Hilbert (Q-Hilbert) spaces are frequently used in applied physical sciences and especially in quantum physics. In order to solve some problems of many nonlinear physical systems, the frame theory of Q-Hilbert spaces was studied. Frames in Q-Hilbert spaces not only retain the frame properties, but also have some advantages, such as a simple structure for approximation. In this paper, we first characterized Hilbert (orthonormal) bases, frames, dual frames and Riesz bases, and obtained the accurate expressions of all dual frames of a given frame by taking advantage of pre-frame operators. Second, we discussed the constructions of frames with the help of the pre-frame operators and gained some more general methods to construct new frames. Moreover, we obtained a necessary and sufficient condition for the finite sum of frames to be a (tight) frame, and the obtained results further enriched and improved the frame theory of the Q-Hilbert space.</p></abstract>

Abstract:

Frames are more stable as compared to bases under the action of a bounded linear operator. Sums of different frames under the action of a bounded linear operator are studied with the help of analysis, synthesis and frame operators. A simple construction of frames from the existing ones under the action of such an operator is presented here. It is shown that a frame can be added to its alternate dual frames, yielding a new frame. It is also shown that the sum of a pair of orthogonal frames is a frame. This provides an easy construction of a frame where the frame bounds can be computed easily. Moreover, for a pair of orthogonal frames, the necessary and sufficient condition is presented for their alternate dual frames to be orthogonal. This allows for an easy construction of a large number of new frames.

Abstract:

In recent years, frames in Krein spaces and several generalizations have been extensively studied. In this paper, we propose an alternative way of looking at the notion of frames in Krein spaces and give a necessary and sufficient condition for a sequence in a Krein space to be a Bessel sequence. We observe that a subsequence of a frame in a Krein space need not be a frame. Also, two complementary subsequences are considered in which one of them is a frame for a Krein space. We obtain necessary and sufficient conditions under which the other one is also a frame for the Krein space.

Abstract:

Generalized frame called g-frame was first proposed using a sequence of adjointable operators to deal with all the existing frames as a united object. In fact, the g-frame is an extension of ordinary frames. Generalized frames with adjointable operators called K-g-frame is a generalization of a g-frame. It can be used to reconstruct elements from the range of a adjointable operator K. K-g-frames have a certain advantage compared with g-frames in practical applications. This paper is devoted to study some properties of K-g-frame in Hilbert C∗ -module, we characterize the concept of K-g-frame by quotient maps. Also discus some result of the dual K-g-Bessel sequences of K-g-frame in Hilbert C∗ -module. Our results are more general than those previously obtained. It is shown that the results we obtained can immediately lead to the existing corresponding results in Hilbert Spaces.

In this paper, we define the discrete time Wilson frame (DTW frame) for l 2 ℤ and discuss some properties of discrete time Wilson frames. Also, we give an interplay between DTW frames and discrete time Gabor frames. Furthermore, a necessary and a sufficient condition for the DTW frame in terms of Zak transform are given. Moreover, the frame operator for the DTW frame is obtained. Finally, we discuss dual pair of frames for discrete time Wilson systems and give a sufficient condition for their existence.

Abstract:

In this paper, the Parseval K-g-frames are constructed from a given K-g-frame by scaling the elements of the K-g-frame with the help of diagonal operators, and these frames are named scalable K-g-frames. Also, we prove some properties of scalable K-g-frames and construct new scalable K-g-frames from a given K-g-frame. The necessary and sufficient conditions for a K-g-frame to be scalable are given. Further, equivalent conditions for the scalability of K-g-frames and the K-frames induced by K-g-frames are obtained. Finally, it is shown that the direct sum of two scalable K-g-frames is again a scalable K-g-frame for some suitable bounded linear operator K.

Abstract:

Frames guide the way in which organizations and individuals interpret their surrounding contexts and shape avenues for thought, action, and behavior. This paper tests the individual-level effects of experiencing ‘frame disputes’: the state of holding individual-level frames that are at odds with dominant organizational frames. We hypothesize that on the individual level a frame dispute will be associated with negative effects on outcomes important for an organization’s functioning. The hypothesis is tested using a survey of a battalion of Italian soldiers. Our results demonstrate that, on average, soldiers who experienced frame disputes in that they perceived their mission differently from the dominant organizational frame displayed significantly lower levels of perceived cohesion, performance, and legitimacy. Frame disputes are likely to be widespread phenomena among organizations and social movements, and understanding their effects has theoretical, empirical, and policy relevance beyond the military case under study.

Abstract:

In this paper we discuss approximately dual frames for a frame or an outer frame of a Hilbert C*-module. We show that every frame or an outer frame, up to a scalar multiple, is approximately dual to itself. This enables us to get a canonical dual frame of a given frame (xn)n as a limit of approximately dual frames defined by (xn)n.

Abstract:

The notion of frame has some generalizations such as frames of subspaces, fusion frames and g-frames. In this paper, we introduce fusion frames and g-frames in Hilbert C*-modules and we show that they share many useful properties with their corresponding notions in Hilbert space. We also generalize a perturbation result in frame theory to g-frames in Hilbert spaces. We also show that tensor product of fusion frames (g-frames) is a fusion frame (g-frame) and tensor product of resolution of identity is a resolution of identity.

Many studies have been doneaccording to different frames of the theory of curves in Euclidean Space. Many scientists have studied frames such as the Frenet frame, Bishop frame, and Adapted frame in this theory. These frames help us in the characterization of curves.In this study, associated curves with the Frenet curve according to the Bishop frame in 4-dimensional Euclidean space are investigated. Direction and rectifying curves of the Frenet curve according to this frame are given.

Abstract:

Abstract Previous research has identified the frames and metaphors used in the reporting on the Euro crisis. War and disease turned out to be the two most frequently used metaphorical frames. Since coverage of the current financial crisis may have a tangible effect on public opinion, research into the effects of metaphorical frames on attitudes is needed. By employing two survey experiments, a student sample (N = 259) and a nonstudent sample (N = 507), this article traces the effects of both metaphorical frames. Our results show that individuals take over the metaphorical frame elements in their evaluation of the Euro crisis. Participants in the war conditions significantly more often referred to war when answering the open questions. Alternatively, when the Euro crisis was framed as a disease, participants were more likely to use words and sentences containing disease frame elements.

Abstract:

Persuasive health education messages can either stress the positive consequences of performing a healthy behaviour (gain-frame) or the negative consequences of not performing a healthy behaviour (loss-frame). Based on studies on topics such as sun protection and breast self-examination there is evidence that messages in different action frames may differ in persuasive effects. Three randomised controlled trials were conducted to test framing effects in nutrition education on specific nutrition-related attitudes and intentions. In study 1, effects of gain-framed and loss-framed messages were studied among 152 adult education students on attitudes and intentions related to fat, fruit and vegetable consumption. In study 2 we confronted 149 regular students with differently framed messages related to a (more or less fictive) preventive dietary behaviour that was expected to be unknown to the study population, intake of flavonoids and risk for chronic disease. The impact on attitudes and intentions to use flavonoid-enriched spreads was studied. In study 3 we studied the effects of differently framed messages on attitudes and intentions related to more immediate and more personally relevant diet nutrition behaviour: folic acid supplement use before and during pregnancy among 100 female students. No significant differences in attitudes or intentions to perform the preventive nutrition behaviours were found between the gain-frame conditions and the loss-frame conditions in all three studies. The (lack of) effects were not moderated by factors such as perceived personal relevance, credibility or novelty of the information, or the perceived importance of the topic addressed. The results of the present studies suggest that action-frame choice has a very limited impact on the effectiveness of nutrition education in changing precautionary motivation.
