The Importance of Being Vigilant: Has ECB Communication Influenced Euro Area Inflation Expectations?
Using daily data on inflation-indexed bonds, we find evidence of a negative relationship between ECB communication regarding risks to price stability - measured on the basis of the frequency and strength of the keyword ‘vigilance’ - and changes in euro area break-even inflation. However, this result is only found for the second half of 2005. At that time, the start of a tightening of ECB monetary policy was increasingly likely. This suggests that communication should be closely in line with policy actions before it can be effective. Still, we also find that the economic significance of this type of communication has been small.central bank communication, ECB, inflation expectations
On the refractive index for a nonmagnetic two-component medium: resolution of a controversy
The refractive index of a dielectric medium comprising both passive and
inverted components in its permittivity was determined using two methods: (i)
in the time domain, a finite-difference algorithm to compute the
frequency-domain reflectance from reflection data for a pulsed plane wave that
is normally incident on a dielectric half-space, and (ii) in the frequency
domain, the deflection of an obliquely incident Gaussian beam on transmission
through a dielectric slab. The dielectric medium was found to be an active
medium with a negative real part for its refractive index. Thereby, a recent
controversy in the scientific literature was resolved.Comment: manuscript submitted to Optics Communication
High School Adolescents’ Perceptions of the Parent–Child Sex Talk: How Communication, Relational, and Family Factors Relate to Sexual Health
This research focuses on how high school adolescents’ (n= 159) perceptions of parent– adolescent communication about sex, including communication frequency, parent–child closeness, parents’ communication competence and effectiveness, as well as the larger family environment relates to sexual risk-taking and permissive sexual attitudes. Findings show that perceived parental communication competence and effectiveness were the strongest negative predictors of adolescents’ permissive sexual attitudes and sexual risk-taking, whereas peer communication frequency was a significant positive predictor. In contrast with previous research, adolescents’ perception of parent communication frequency and family communication climate (e.g., conversation orientation and conformity orientation) was unrelated to adolescents’ sexual risk
JARINGAN KOMUNIKASI ANTAR MAHASISWA PEMAIN JUDI ONLINE DALAM APLIKASI HIGGS DOMINO DI KOTA MALANG
The development of technology and information has enabled many aspects to be conducted digitally, leading to both positive and negative impacts for its users. One of the negative impacts is the increasing prevalence of online gambling phenomena among university students. Engaging in online gambling entails communication among players, thus forming a communication network. This study aims to analyze the communication network structure among university student online gamblers in the Higgs Domino application in the city of Malang. Additionally, it seeks to identify the factors that drive students to engage in online gambling practices. The method used in this research is descriptive qualitative. Data collection techniques involved interviews with research subjects conducted using snowball sampling theory. Once data was obtained, it was collected and analyzed using sociometric analysis techniques. Utilizing sociogram analysis via the UCINET 6.0 application, this study successfully identified a Y-shaped communication pattern within the network. Moreover, the research explored individual characteristic variables including age, level of formal education, level of social media ownership, and frequency of playing Higgs Domino online gambling as supportive factors in understanding the researched phenomenon. Based on interview results, it was found that individuals are interested in playing online gambling due to several factors: influence from friends or environment; desire to obtain a large amount of money quickly without working; seeking entertainment and feeling bored or saturated; easy internet access; and difficulty in self-control to refrain from gambling
Positive words carry less information than negative words
We show that the frequency of word use is not only determined by the word
length \cite{Zipf1935} and the average information content
\cite{Piantadosi2011}, but also by its emotional content. We have analyzed
three established lexica of affective word usage in English, German, and
Spanish, to verify that these lexica have a neutral, unbiased, emotional
content. Taking into account the frequency of word usage, we find that words
with a positive emotional content are more frequently used. This lends support
to Pollyanna hypothesis \cite{Boucher1969} that there should be a positive bias
in human expression. We also find that negative words contain more information
than positive words, as the informativeness of a word increases uniformly with
its valence decrease. Our findings support earlier conjectures about (i) the
relation between word frequency and information content, and (ii) the impact of
positive emotions on communication and social links.Comment: 16 pages, 3 figures, 3 table
On the Resolution of the Time-Like Singularities in Reissner-Nordstrom and Negative-Mass Schwarzschild
Certain time-like singularities are shown to be resolved already in classical
General Relativity once one passes from particle probes to scalar waves. The
time evolution can be defined uniquely and some general conditions for that are
formulated. The Reissner-Nordstrom singularity allows for communication through
the singularity and can be termed "beam splitter" since the transmission
probability of a suitably prepared high energy wave packet is 25%. The high
frequency dependence of the cross section is w^{-4/3}. However, smooth
geometries arbitrarily close to the singular one require a finite amount of
negative energy matter. The negative-mass Schwarzschild has a qualitatively
different resolution interpreted to be fully reflecting. These 4d results are
similar to the 2d black hole and are generalized to an arbitrary dimension d>4.Comment: 47 pages, 5 figures. v2: See end of introduction for an important

Knowledge Communication in Product Development Projects
During the last decades, a number of studies have been concerned with com-munication related to new product development. These have looked at either intra-organizational communication between departments or communication between new product development teams and external stakeholders such as customers or suppliers. Only little research, however, has combined internal and external stakeholder communication and explored the role of technology uncertainty on communication. The purpose of this study is to examine how technology uncertainty affects project manager communication behavior during new product development. We carried out an embedded case study of a major NPD project in the automation industry. The findings indicate that technology uncertainty is positively related to communication frequency between project manager and project stakeholders during the early phase of NPD project. In addition we found a negative association between technology uncertainty and the breadth and depth of communication between project manager and stakeholders in early phase of the NPD project. These findings indicate that under high technology uncertainty, managers of NPD projects modify their communication behavior not only with respect to how frequently they communicate with stakeholders, but also to which stakeholders they communicate and how deeply they engage different stakeholders in different phases of the new product development project.
Teacher Perceptions Of Parent-Teacher Communications And Practice
It has been established in prior research that parent involvement and school-family partnerships have the potential to positively impact student achievement; however, creating and maintaining positive and productive parent-teacher communication can be difficult. Since teachers function as the link between school and the home, there is an increased need to study the perspectives and experiences of teachers. The purpose of this study was to examine the relationship between teacher perceptions of parent-teacher relationships, teacher conversation competence, and teacher communication frequency with parents.
This study involved an online survey distributed to 234 participants via Amazon Mechanical Turk. The following results were found to be significant: teacher relationship beliefs and the presence of a teacher contact mandate had a negative correlation with communication frequency, and teacher conversation competence had a positive correlation with communication frequency. In regression analysis, relationship beliefs and contact mandate were suggested to be significant negative predictors of communication frequency, whereas conversation competence was a significant positive predictor. SEM analysis suggested that only conversation competence was a significant predictor of communication frequency, which raises questions about the potential for mediation.
The major limitation of this study was the lack of convergent validity, which could have arisen due to issues with individual measures and exacerbated by a heterogeneous and potentially uncommitted online sample pool. Potential implications of this study include providing information to inform current teaching practice and improving teacher education and professional development. If teachers feel more prepared entering into parent-teacher dialogue, student achievement could be improved
The law of brevity in macaque vocal communication is not an artifact of analyzing mean call durations
Words follow the law of brevity, i.e. more frequent words tend to be shorter.
From a statistical point of view, this qualitative definition of the law states
that word length and word frequency are negatively correlated. Here the recent
finding of patterning consistent with the law of brevity in Formosan macaque
vocal communication (Semple et al., 2010) is revisited. It is shown that the
negative correlation between mean duration and frequency of use in the
vocalizations of Formosan macaques is not an artifact of the use of a mean
duration for each call type instead of the customary 'word' length of studies
of the law in human language. The key point demonstrated is that the total
duration of calls of a particular type increases with the number of calls of
that type. The finding of the law of brevity in the vocalizations of these
macaques therefore defies a trivial explanation.Comment: Little improvements of the statistical argument
