It is naturally easier to comprehend simple code relative to complicated code. Regrettably, there is little agreement on how to effectively measure code complexity. As a result simple generalpurpose metrics are often used, such as lines of code (LOC), Mc- Cabe's cyclomatic complexity (MCC), and Halstead's metrics. But such metrics just count syntactic features, and ignore details of the code's global structure, which may also have an effect on understandability. In particular, we suggest that code regularity-where the same structures are repeated time after time-may significantly reduce complexity, because once one figures out the basic repeated element it is easier to understand additional instances. We demonstrate this by controlled experiments where subjects perform cognitive tasks on different versions of the same basic function. The results indicate that versions with significant regularity lead to better comprehension, while taking similar time, despite being longer and having higherMCC. These results indicate that regularity is another attribute of code that should be taken into account in the context of studying the code's complexity and comprehension. Moreover, the fact that regularity may compensate for LOC and MCC demonstrates that complexity cannot be decomposed into independently addable contributions by individual attributes.

In this paper we address some issues related to the mutual influence between the PHY layer building blocks (FEC blocks) and the MAC level allocations in IEEE 802.16e /WiMAX systems, in order to increase the overall PHY and MAC combined efficiency. In these systems transmissions are carried in physical Bursts, both on the Uplink and Downlink channels. Bursts are composed of slots, which are grouped into FEC blocks. The number of slots in a Burst determines the length and number of the FEC blocks. The FEC blocks have a direct influence on the probability that bits are received successfully, and thus on the Burst Goodput, which is defined as the ratio between the average number of bits in the Burst that arrive successfully at the receiver, to the Burst length. In this paper we address a new coupled PHY and MAC scheduling methodology by investigating the relationship between the Burst length and its Goodput in different Modulation/Coding schemes, and investigate, given a Burst, the most efficient such scheme. The outcomes of the paper are twofold: first we show that the Goodput of a Burst is almost not dependent on its length. Second, we show that in most cases, the most efficient Modulation/Coding scheme is the one that enables us to transmit the largest number of bits in a Burst. However, there are a few cases where this is not the case. We show these cases in the paper. © 2010 Elsevier B.V.

Objectives: This study aims to examine competing explanations of the relationship between religious and political ideology commitment with posttraumatic growth. Method: Subjects were Israeli youth who were exposed to terror (n = 2,999) aged 13-15. Measures included: posttraumatic growth inventory, religious orientation, ideological commitment, objective and subjective exposure to terror. Results: Both religiosity and political ideology mediated the effects of exposure and fear on growth. Political ideology but not religiosity, had a moderating effect, such that subjective fear was positively associated with growth only among those with stronger ideologies. Conclusion: Results support the contention of Terror Management Theory that cultural beliefs have beneficial effects on well being in the face of adversity and emphasize the role of cultural world as effecting growth, beyond trauma. © Springer-Verlag 2009.

Higher education institutions (HEIs) are often curious whether students will be successful or not during their study. Before or during their courses the academic institutions try to estimate the percentage of successful students. But is it possible to predict the success rate of students enrolled in their courses? Are there any specific student characteristics, which can be associated with the student success rate? Is there any relevant student data available to HEIs on the basis of which they could predict the student success rate? The answers to the above research questions can generally be obtained using data mining tools. Unfortunately, data mining algorithms work best with large data sets, while student data, available to HEIs, related to courses are limited and falls into the category of small data sets. Thus, the study focuses on data mining for small student data sets and aims to answer the above research questions by comparing two different data mining tools. The conclusions of this study are very promising and will encourage HEIs to incorporate data mining tools as an important part of their higher education knowledge management systems. © 2014 Elsevier Ltd.

We compare between the Throughput performance of IEEE 802.11n and IEEE 802.11ac under the same PHY conditions and in the three aggregation schemes that are possible in the MAC layer of the two protocols. We find that for an error-free channel 802.11ac outperforms 802.11n due to its larger frame sizes, except for the case where there is a limit on the number of aggregated packets. In an error-prone channel the bit error rate sometimes determines the optimal frame sizes. Together with the limit on the number of aggregated packets, these two factors limit the advantage of 802.11ac. © 2014 Elsevier B.V.

We give an overview of results on amorphic association schemes. We give the known constructions of such association schemes, and enumerate most such association schemes on up to 49 vertices. Special attention is paid to cyclotomic association schemes. We give several results on when a strongly regular decomposition of the complete graph is an amorphic association scheme. This includes a new proof of the result that a decomposition of the complete graph into three strongly regular graphs is an amorphic association scheme, and the new result that a strongly regular decomposition of the complete graph for which the union of any two relations is again strongly regular must be an amorphic association scheme. © 2009 Elsevier Inc.

This study explores the interrelations between humorous texts and the memory of traumatic events through an analysis of skits aired on Israeli television that are related to Holocaust memory. The study presents a typology of these skits indicating an evolutionary development: from the use of humor to criticize Holocaust remembrance to the use of Holocaust memory to create humorous effects. Contextualizing these findings in the fields of media memory and trauma theory, the study argues that this evolutionary development challenges the hegemonic commemorative discourse of the Holocaust: while commemorative discourse plays a distinctive role in performing cultural trauma, the media's humorous discourse conveys a sacrilegious viewpoint and thus can play a vital role in recuperating from it. © 2014 International Communication Association

In this article, we discuss the crucial subject of RFID tags with double rectangular spiral antennas, system stability optimization under delayed electromagnetic interference and parasitic effects. Two antennas are connected in series by microstrip line with parasitic effects. We define V1(t) as the voltage on the first antenna inductance and V2(t) as the voltage on the second antenna inductance. Due to electromagnetic interference there are differences in time delays, with respect to the first and second rectangular spiral antennas voltages and voltage derivatives. The delayed voltages are V1(t - τ1) and V2(t - τ2) respectively (τ1 ≠ τ2) and the delayed voltage derivatives are dV1(t - Δ1)/dt, dV2(t - Δ2)/dt respectively Δμ. Additionally, there is a delay in time for the microstrip parasitic effects Δμ. The double rectangular spiral antenna system equivalent circuit can be described in terms of delayed differential equations, depending on variable parameters and delays. The stability of a given steady state is determined by the graphs of some function of τ1, τ2, Δ1, Δ2 and Δμ. © 2015 IEEE.

According to orthodox psychoanalytical theory, narcissism and homosexuality are strongly associated. This association played a major role in pathologizing homosexuality. The present study compared self-esteem and two measures of narcissism among 90 homosexual and 109 heterosexual male students, who filled in a demographic questionnaire, Rosenberg's Self-Esteem Scale, the Narcissistic Personality Inventory, and the Pathological Narcissism Inventory, which addresses both grandiose and vulnerable subtypes of narcissism. The hypothesis, which is based on the Freudian connection between narcissism and homosexuality, is supported by the results, indicating that the homosexual students score higher in both measures of narcissism and lower on the self-esteem measure, compared to their heterosexual counterparts. Intra-psychic, as well as environmental, interpretations of the results are suggested in the discussion. Copyright © Taylor & Francis Group, LLC.

This research analyzes Greenpeace International Unfriend Coal protest campaign against Facebook's energy policy (2010-2011), as a case study in the organization's approach to campaigning on climate change issues. In the context of Greenpeace protest history and social movement research, we focus on the online mobilization tactics used by Greenpeace, and how they differed from previous campaign practices. The findings are based on a content analysis of all statuses posted on the campaign Facebook page (N = 119), and six semi-structured interviews with key Greenpeace personnel. The analysis reveals that Greenpeace used Facebook extensively both for disseminating information and context about the campaign, and as a platform for mobilizing and facilitating broad public engagement. Greenpeace seized the affordances of the Facebook platform and introduced new means of online mobilization and engagement. These e-tactics proved effective for engaging diverse transnational supporters in the campaign. The implications for environmental non-governmental organizations and the broader environmental movement are discussed. © 2014 Taylor & Francis.
