text: 'In a longitudinal naturalistic study, we observed German mothers interacting
with their infants when they were 3 and 6 months old. Pursuing the idea that infants’
attention is socialized in everyday interactions, we explored whether eye contact
is reinforced selectively by behavioral modification in the input provided to
infants. Applying a microanalytical approach focusing on the sequential organization
of interaction, we explored how the mother draws the infant’s attention to herself
and how she tries to maintain attention when the infant is looking at her. Results
showed that eye contact is reinforced by specific infant-directed practices: interrogatives
and conversational openings, multimodal stimulation, repetition, and imitation.
In addition, these practices are contingent on the infant’s own behavior. By comparing
the two data points (3 and 6 months), we showed how the education of attention
evolves hand-in-hand with the developing capacities of the infant.'

text: Piezoelectric inertia motors use the inertia of a body to drive it by means
of a friction contact in a series of small steps. These motors can operate in
``stick-slip'' or ``slip-slip'' mode, with the fundamental frequency of the driving
signal ranging from several Hertz to more than 100 kHz. To predict the motor characteristics,
a Coulomb friction model is sufficient in many cases, but numerical simulation
requires microscopic time steps. This contribution proposes a much faster simulation
technique using one evaluation per period of the excitation signal. The proposed
technique produces results very close to those of timestep simulation for ultrasonics
inertia motors and allows direct determination of the steady-state velocity of
an inertia motor from the motion profile of the driving part. Thus it is a useful
simulation technique which can be applied in both analysis and design of inertia
motors, especially for parameter studies and optimisation.

text: 'SCM is a simple, modular and flexible system for web monitoring and customer
interaction management. In our view, its main advantages are the following: It
is completely web based. It combines all technologies, data, software agents and
human agents involved in the monitoring and customer interaction process. It can
be used for messages written in any natural language. Although the prototype of
SCM is designed for classifying and processing messages about mobile-phone related
problems in social networks, SCM can easily be adapted to other text types such
as discussion board posts, blogs or emails. Unlike comparable systems, SCM uses
linguistic technologies to classify messages and recognize paraphrases of product
names. For two reasons, product name paraphrasing plays a major role in SCM: First,
product names typically have many, sometimes hundreds or thousands of intralingual
paraphrases. Secondly, product names have interlingual paraphrases: The same products
are often called or spelt differently in different countries and/or languages.
By mapping product name variants to an international canonical form, SCM allows
for answering questions like Which statements are made about this mobile phone
in which languages/in which social networks/in which countries/...? The SCM product
name paraphrasing engine is designed in such a way that standard variants are
assigned automatically, regular variants are assigned semiautomatically and idiosyncratic
variants can be added manually. With this and similar features we try to realize
our philosophy of simplicity, modularity and flexibility: Whatever can be done
automatically is done automatically. But manual intervention is always possible
and easy and it does not conflict in any way with the automatic functions of SCM.'

text: Within this paper, we will describe a new approach to customer interaction
management by integrating social networking channels into existing business processes.
Until now, contact center agents still read these messages and forward them to
the persons in charge of customer’s in the company. But with the introduction
of Web 2.0 and social networking clients are more likely to communicate with the
companies via Facebook and Twitter instead of filling data in contact forms or
sending e-mail requests. In order to maintain an active communication with international
clients via social media, the multilingual consumer contacts have to be categorized
and then automatically assigned to the corresponding business processes (e.g.
technicalservice, shipping, marketing, and accounting). This allows the company
to follow general trends in customer opinions on the Internet, but also record
two-sided communication for customer relationship management.

text: Since customers first share their problems with a social networking community
before directly addressing a company, social networking sites such as Facebook,
Twitter, MySpace or Foursquare will be the interface between customer and company.
For this reason, it is assumed that social networks will evolve into a common
communication channel – not only between individuals but also between customers
and companies. However, social networking has not yet been integrated into customer
interaction management (CIM) tools. In general, a CIM application is used by the
agents in a contact centre while communicating with the customers. Such systems
handle communication across multiple different channels, such as e-mail, telephone,
Instant Messaging, letter etc. What we do now is to integrate social networking
into CIM applications by adding another communication channel. This allows the
company to follow general trends in customer opinions on the Internet, but also
record two-sided communication for customer service management and the company’s
response will be delivered through the customer’s preferred social networking
site.

text: 'A profound description of friction in wheel--rail contact plays an essential
role for optimization of traction control strategies, as input quantity for railway
simulations in general and for the estimation of wear and rolling contact fatigue.
A multitude of wheel--rail contact models exists, however, traction--creepage
curves obtained from measurements show quantitative and qualitative deviations.
There are several phenomena which influence the traction--creepage characteristics:
Mechanisms resulting from surface roughness, frictional heating or the presence
of interfacial fluids can have a dominating influence on friction. In this paper,
a new wheel--rail contact model, accounting for these influential parameters,
will be presented. The presented model accounts for the interaction of an interfacial
fluid model for combined boundary and mixed lubrication of rough surfaces with
a wheel--rail contact model that additionally accounts for frictional heating.
A quantitative comparison with measurements found in the literature is not conducted,
since the exact conditions of the measurements are mostly unknown and parameters
can easily be adjusted to fit the measurements. Emphasis is placed on the qualitative
behavior of the model with respect to the measurements and good agreement is found.
The dependence of the maximum traction coefficient on rolling velocity, surface
roughness and normal load is studied under dry and water lubricated conditions.'

text: In the modeling of piezoelectric Langevin transducers using usual transfer
matrix methods, some simplifications have been adopted. This leads to reduction
of the model quality. A mixed transfer matrix method is employed in the modeling
of Langevin transducers, where the pre-stressed bolt is modeled as a separate
four-pole element, which is connected to other elements in parallel. Based on
the mixed transfer matrix method, the four (six)-pole element description of the
piezoelectric Langevin transducer is built up and the total transfer matrix relation
is derived. The resonance frequencies of the transducer are calculated and then
measured using the impedance analyzer (HP4192). Experimental result shows that
the mixed transfer matrix method has better modeling quality than the usual transfer
matrix method for the vibration analysis of piezoelectric Langevin transducers.

text: A simple pre-stress estimate method of Langevin transducers is studied. The
measurement setup consists of a capacitor, an impedance converter and a voltmeter.
Based on the piezoelectric equation and the basic circuit theory, the mathematical
expression between the pre-stress and the voltage across the capacitor is derived.
The pre-stress level can then be calculated out of the measurement of the capacitor
voltage. In order to evaluate the precision of this method, a force washer is
used to measure the pre-stress of the Langevin transducer. The result shows the
pre-stress level obtained from this method is 30-40\% higher than the pre-stress
level measured by the force washer. This method is simple and can be used to estimate
the pre-stress of various Langevin transducers. The precision of this method can
be raised if d33 is identified under different pre-stress levels.

text: Many ultrasonic processes are based on the mechanical contact of oscillating
parts. Within ultrasonic machining (drilling, milling, grinding) micro impacts
lead to abrasion at the processed workpiece and hopefully do not damage the tool.
In ultrasonic motors ideally neither part gets worn. Thus the appropriate design
of contact partners as well as their kinematics is a substantial task during the
development of such devices. A first step to optimize contact mechanics is to
understand their behavior and dependencies on parameter variations, such as vibration
amplitude and pre-stress of the impacting parts. For a detailed understanding
models validated with convincing experimental data from measurements are absolutely
essential. This paper focuses on simple vibro-impact experiments which can be
used as benchmark data for future models. The setup of the experiment and first
experimental investigations are described in detail.

text: "Two parameters of language production, the partner model and the mentally
represented knowledge\r\nabout a spatial constellation, are investigated with
respect to their influence on spatial reference. At\r\nissue is whether the verbally
expressed point of view in route directions is primarily influenced by the\r\nneeds
of the partner or by the underlying mental representation of the speaker stemming
from his or\r\nher own experience with an object. Two experiments in which participants
(N 5 90) were asked to\r\nproduce a set of route directions are reported. The
experimental situation was such that the point of\r\nview of the speaker did not
correspond to the point of view of the partner. The results show that more\r\nparticipants
localize from their own point of view than from the point of view of the partner.\r\nDiscussion
centers on the fact that speakers do not always behave in a truly partner-oriented
manner."
