text: "Abstract\r\n \r\n Background\r\n
\ Research on procrastination mostly focuses on person‐related
antecedents and neglects situational and social factors, such as group work. Prior
research indicates that conjunctive and additive group work may increase individual
effort and performance as compared to individual work.\r\n \r\n
\ \r\n Aims\r\n
\ Based on these findings, we investigate whether conjunctive
and additive group work may also help reduce procrastination as compared to individual
work.\r\n \r\n \r\n
\ Methods\r\n \r\n
\ In a registered field experiment,\r\n N\r\n
\ = 218 students with high levels of trait procrastination
worked on an academic task over the course of 10 days in one of three conditions
(individual work vs. conjunctive group work vs. additive group work). Dependent
variables comprised task procrastination, task performance, and positive and negative
task‐related affect.\r\n \r\n \r\n
\ \r\n Results\r\n
\ Regarding conjunctive group work, results are mixed,
with some evidence that conjunctive group work leads to lower procrastination
as compared to individual work. Both types of group work resulted in higher negative
task‐related affect when assessed prospectively. No other effects were found.\r\n
\ \r\n \r\n Conclusions\r\n
\ The findings contribute to the idea that targeted
changes in the learning environment, such as the implementation of group work,
may help reduce procrastination.\r\n "

text: Information Systems (IS) is rooted in systems theory. Systems theory offers
powerful concepts to address challenges of growing system complexity and non-systemic
design approaches in information systems. Despite its systemic origins, systems
theory remains a peripheral topic in IS. The study addresses this gap by introducing
a comprehensive framework of 52 systems-theoretical concepts to guide the design
of complex IS artifacts. We synthesize scattered systems knowledge from diverse
disciplines to provide a unified level of abstraction for complex information
system design. We apply the framework to a use case of business reputation systems
to show how the systems lens informs the design of a novel, complex information
system. We make three key contributions to the literature. First, the framework
provides a common ground for interdisciplinary research in information system
design. Second, it offers a unified level of abstraction grounded in systems theory
that serves as a coherent basis for artifact design. Third, it demonstrates the
potential of systems theory as a foundational justificatory knowledge base. Furthermore,
we provide guidance on applying the framework across multiple modes of reasoning,
alongside further application guidelines. The study thus serves as a bridge between
the body of systems knowledge and contextual design in IS.

text: Metasurfaces are powerful tools for manipulating light using small structures
on the nanoscale. In most metasurfaces, near-field couplings are treated as being
unfavorable perturbations. Here, we experimentally investigate a structure consisting
of sinusoidally modulated silicon waveguides where near-field coupling of local
resonances leads to negative coupling, i.e., a negative coupling constant. This
gives rise to wave-vector-dependent eigenstates of elliptical, linear, and circular
polarizations. In particular, fully circular polarization states are not only
present at a single point in momentum space (k-space) but also along a line. This
circular polarization line, as well as a linear polarization line, emanates from
a polarization degeneracy at the Dirac point. We experimentally validate the existence
of these eigenstates and demonstrate the energy-, polarization-, and wave vector
dependence of this metasurface as well as its sensitivity to fabrication tolerances.
By tuning the incident k-vector, certain polarization-energy eigenstates are strongly
reflected, allowing for uses in angle-tunable polarization filters and light sources.

text: "Trust between client and consultant is perhaps the most important asset in
con-sulting, as this is a highly intangible knowledge-intensive business that
concerns is-sues of outstanding strategic and operational importance for the customers.
Cli-ents who have not worked with a particular consultancy face considerable risk
when they place an order while lacking reliable information about the service
quality they can expect. There is a strong link between trust and reputation,
as the positive reputation of a consultancy can act as a substitute for a new
client’s missing individual experience with the provider, fostering trust in the
service quali-ty. Thus, creating, maintaining, and demonstrating a good reputation
is of signifi-cant importance for consultancies in a very competitive industry.\r\nTo
facilitate trustworthy signals, we design and implement a novel reputation mechanism
that carries a monetary weight stored on a blockchain network as an immutable,
decentralized, and transparent ledger. Based on an implementation in the Ethereum
network and subsequent evaluation, we conclude that the reputation mechanism can
contribute to leveling information asymmetry and reducing risk while increasing
reputation and trust. The mechanism lends itself to being used in other business-to-business
scenarios that suffer from similar information asymmetries."

text: We determine the asymptotic growth of extensions of local function fields
of characteristic p counted by discriminant, where the Galois group is a subgroup
of the affine group AGL_1(p). More general, we solve the corresponding counting
problems for all groups which arise in a tower of a cyclic extension of order
p over a cyclic extension of degree d coprime to p. This in particular give answers
for certain non-abelian groups including S_3, dihedral groups of order 2p, and
many Frobenius groups.

text: Backchannels and fillers are important linguistic expressions in dialogue,
but often treated as ‘noise’ to be bypassed in modern transformer-based language
models. Our work studies the representation of them in language models using three
fine-tuning strategies. The models are trained on three dialogue corpora in English
and Japanese, where backchannels and fillers are preserved and annotated, to investigate
how fine-tuning can help LMs learn their representations. We first apply clustering
analysis to the learnt representation of backchannels and fillers, and have found
increased silhouette scores in representations from fine-tuned models, which suggests
that fine-tuning enables LMs to distinguish the nuanced semantic variation in
different backchannel and filler use. We also use natural language generation
(NLG) metrics and qualitative analysis to confirm that the utterances generated
by fine-tuned language models resemble human-produced utterances more closely.
Our findings suggest the potentials of transforming general LMs into conversational
LMs that are more capable of producing human-like languages adequately.

text: 'Recent theoretical advancement of information density in natural language
has brought the following question on desk: To what degree does natural language
exhibit periodicity pattern in its encoded information? We address this question
by introducing a new method called AutoPeriod of Surprisal (APS). APS adopts a
canonical periodicity detection algorithm and is able to identify any significant
periods that exist in the surprisal sequence of a single document. By applying
the algorithm to a set of corpora, we have obtained the following interesting
results: Firstly, a considerable proportion of human language demonstrates a strong
pattern of periodicity in information; Secondly, new periods that are outside
the distributions of typical structural units in text (e.g., sentence boundaries,
elementary discourse units, etc.) are found and further confirmed via harmonic
regression modeling. We conclude that the periodicity of information in language
is a joint outcome from both structured factors and other driving factors that
take effect at longer distances. The advantages of our periodicity detection method
and its potentials in LLM-generation detection are further discussed.'
