text: Timing plays a crucial role in the context of information security investments.
We regard timing in two dimensions, namely the time of announcement in relation
to the time of investment and the time of announcement in relation to the time
of a fundamental security incident. The financial value of information security
investments is assessed by examining the relationship between the investment announcements
and their stock market reaction focusing on the two time dimensions. Using an
event study methodology, we found that both dimensions influence the stock market
return of the investing organization. Our results indicate that (1) after fundamental
security incidents in a given industry, the stock price will react more positively
to a firm’s announcement of actual information security investments than to announcements
of the intention to invest; (2) the stock price will react more positively to
a firm’s announcements of the intention to invest after the fundamental security
incident compared to before; and (3) the stock price will react more positively
to a firm’s announcements of actual information security investments after the
fundamental security incident compared to before. Overall, the lowest abnormal
return can be expected when the intention to invest is announced before a fundamental
information security incident and the highest return when actual investing after
a fundamental information security incident in the respective industry.

text: "Literature reviews (LRs) play an important role in the development of domain
knowledge in all fields. Yet, we observe a\r\nlack of insights into the activities
with which LRs actually develop knowledge. To address this important gap, we (1)\r\nderive
knowledge building activities from the extant literature on LRs, (2) suggest a
knowledge-based typology of LRs\r\nthat complements existing typologies, and (3)
apply the suggested typology in an empirical study that explores how LRs\r\nwith
different goals and methodologies have contributed to knowledge development. The
analysis of 240 LRs published\r\nin 40 renowned IS journals between 2000 and 2014
allows us to draw a detailed picture of knowledge development\r\nachieved by one
of the most important genres in the IS field. An overarching contribution of our
work is to unify extant\r\nconceptualizations of LRs by clarifying and illustrating
how LRs apply different methodologies in a range of knowledge\r\nbuilding activities
to achieve their goals with respect to theory."

text: "Today, organizations must deal with a plethora of IT security threats and
to ensure smooth and\r\nuninterrupted business operations, firms are challenged
to predict the volume of IT security vulnerabilities\r\nand allocate resources
for fixing them. This challenge requires decision makers to assess\r\nwhich system
or software packages are prone to vulnerabilities, how many post-release vulnerabilities\r\ncan
be expected to occur during a certain period of time, and what impact exploits
might have.\r\nSubstantial research has been dedicated to techniques that analyze
source code and detect security\r\nvulnerabilities. However, only limited research
has focused on forecasting security vulnerabilities\r\nthat are detected and reported
after the release of software. To address this shortcoming, we apply\r\nestablished
methodologies which are capable of forecasting events exhibiting specific time
series\r\ncharacteristics of security vulnerabilities, i.e., rareness of occurrence,
volatility, non-stationarity,\r\nand seasonality. Based on a dataset taken from
the National Vulnerability Database (NVD), we use\r\nthe Mean Absolute Error (MAE)
and Root Mean Square Error (RMSE) to measure the forecasting\r\naccuracy of single,
double, and triple exponential smoothing methodologies, Croston's methodology,\r\nARIMA,
and a neural network-based approach. We analyze the impact of the applied forecasting\r\nmethodology
on the prediction accuracy with regard to its robustness along the dimensions
of the\r\nexamined system and software package \"operating systems\", \"browsers\"
and \"office solutions\" and\r\nthe applied metrics. To the best of our knowledge,
this study is the first to analyze the effect\r\nof forecasting methodologies
and to apply metrics that are suitable in this context. Our results\r\nshow that
the optimal forecasting methodology depends on the software or system package,
as some\r\nmethodologies perform poorly in the context of IT security vulnerabilities,
that absolute metrics\r\ncan cover the actual prediction error precisely, and
that the prediction accuracy is robust within the\r\ntwo applied forecasting-error
metrics."

text: In disaster operations management, a challenging task for rescue organizations
occurs when they have to assign and schedule their rescue units to emerging incidents
under time pressure in order to reduce the overall resulting harm. Of particular
importance in practical scenarios is the need to consider collaboration of rescue
units. This task has hardly been addressed in the literature. We contribute to
both modeling and solving this problem by (1) conceptualizing the situation as
a type of scheduling problem, (2) modeling it as a binary linear minimization
problem, (3) suggesting a branch-and-price algorithm, which can serve as both
an exact and heuristic solution procedure, and (4) conducting computational experiments
- including a sensitivity analysis of the effects of exogenous model parameters
on execution times and objective value improvements over a heuristic suggested
in the literature - for different practical disaster scenarios. The results of
our computational experiments show that most problem instances of practically
feasible size can be solved to optimality within ten minutes. Furthermore, even
when our algorithm is terminated once the first feasible solution has been found,
this solution is in almost all cases competitive to the optimal solution and substantially
better than the solution obtained by the best known algorithm from the literature.
This performance of our branch-and-price algorithm enables rescue organizations
to apply our procedure in practice, even when the time for decision making is
limited to a few minutes. By addressing a very general type of scheduling problem,
our approach applies to various scheduling situations.

text: Scheduling problems are essential for decision making in many academic disciplines,
including operations management, computer science, and information systems. Since
many scheduling problems are NP-hard in the strong sense, there is only limited
research on exact algorithms and how their efficiency scales when implemented
on parallel computing architectures. We address this gap by (1) adapting an exact
branch-and-price algorithm to a parallel machine scheduling problem on unrelated
machines with sequence- and machine-dependent setup times, (2) parallelizing the
adapted algorithm by implementing a distributed-memory parallelization with a
master/worker approach, and (3) conducting extensive computational experiments
using up to 960 MPI processes on a modern high performance computing cluster.
With our experiments, we show that the efficiency of our parallelization approach
can lead to superlinear speedup but can vary substantially between instances.
We further show that the wall time of serial execution can be substantially reduced
through our parallelization, in some cases from 94 hours to less than six minutes
when our algorithm is executed on 960 processes.

text: Recommender Agents (RAs) facilitate consumers’ online purchase decisions for
complex, multi-attribute products. As not all combinations of attribute levels
can be obtained, users are forced into trade-offs. The exposure of trade-offs
in a RA has been found to affect consumers’ perceptions. However, little is known
about how different preference elicitation methods in RAs affect consumers by
varying degrees of trade-off exposure. We propose a research model that investigates
how different levels of trade-off exposure cognitively and affectively influence
consumers’ satisfaction with RAs. We operationalize these levels in three different
RA types and test our hypotheses in a laboratory experiment with 116 participants.
Our results indicate that with increasing tradeoff exposure, perceived enjoyment
and perceived control follow an inverted Ushaped relationship. Hence, RAs using
preference elicitation methods with medium trade-off exposure yield highest consumer
satisfaction. This contributes to the understanding of trade-offs in RAs and provides
valuable implications to e-commerce practitioners.

text: When responding to natural disasters, professional relief units are often
supported by many volunteers which are not affiliated to humanitarian organizations.
The effective coordination of these volunteers is crucial to leverage their capabilities
and to avoid conflicts with professional relief units. In this paper, we empirically
identify key requirements that professional relief units pose on this coordination.
Based on these requirements, we suggest a decision model. We computationally solve
a real-world instance of the model and empirically validate the computed solution
in interviews with practitioners. Our results show that the suggested model allows
for solving volunteer coordination tasks of realistic size near-optimally within
short time, with the determined solution being well accepted by practitioners.
We also describe in this article how the suggested decision support model is integrated
in the volunteer coordination system which we develop in joint cooperation with
a disaster management authority and a software development company.

text: The need to protect resources against attackers is reflected by huge information
security investments of firms worldwide. In the presence of budget constraints
and a diverse set of assets to protect, organizations have to decide in which
IT security measures to invest, how to evaluate those investment decisions, and
how to learn from past decisions to optimize future security investment actions.
While the academic literature has provided valuable insights into these issues,
there is a lack of empirical contributions. To address this lack, we conduct a
theory-based exploratory multiple case study. Our case study reveals that (1)
firms? investments in information security are largely driven by external environmental
and industry-related factors, (2) firms do not implement standardized decision
processes, (3) the security process is perceived to impact the business process
in a disturbing way, (4) both the implementation of evaluation processes and the
application of metrics are hardly existent and (5) learning activities mainly
occur at an ad-hoc basis.

text: We consider Max-min Share (MmS) fair allocations of indivisible chores (items
with negative utilities). We show that allocation of chores and classical allocation
of goods (items with positive utilities) have some fundamental connections but
also differences which prevent a straightforward application of algorithms for
goods in the chores setting and viceversa. We prove that an MmS allocation does
not need to exist for chores and computing an MmS allocation - if it exists -
is strongly NP-hard. In view of these non-existence and complexity results, we
present a polynomial-time 2-approximation algorithm for MmS fairness for chores.
We then introduce a new fairness concept called optimal MmS that represents the
best possible allocation in terms of MmS that is guaranteed to exist. We use connections
to parallel machine scheduling to give (1) a polynomial-time approximation scheme
for computing an optimal MmS allocation when the number of agents is fixed and
(2) an effective and efficient heuristic with an ex-post worst-case analysis.

text: Design science is a fundamental research stream that contends its position
in the information systems discipline. While ongoing debates address the relative
importance of design science contributions in the information systems community,
insights into the scientific impact of design science research (DSR) are missing
and this lack of understanding arguably poses challenges to an informed discourse.
To identify the most influential papers and those factors that explain their scientific
impact, this paper presents an exploratory study of the scientific impact of DSR
papers published in the AIS Senior Scholars' Basket of Journals. We uncover the
current DSR landscape by taking stock of influential papers and theories and develop
a model to explain the scientific impact of DSR papers. Our findings show that
scientific impact is significantly explained by theorization and novelty. We discuss
how the implications of our work can be projected on the overarching discourse
on DSR.

text: 'Literature reviews (LRs) are recognized for their increasing impact in the
information systems literature. Methodologists have drawn attention to the question
of how we can leverage the value of LRs to preserve and generate knowledge. The
panelists who participated in the discussion of ?Standalone Literature Reviews
in IS Research: What Can Be Learnt from the Past and Other Fields?? at ICIS 2016
in Dublin acknowledged this significant issue and debated a) what the IS field
can learn from other fields and where IS-specific challenges occur, b) how the
IS field should move forward to foster the genre of LRs, and c) what best practices
are to train doctoral IS students in publishing LRs. This article reports the
key takeaways of this panel discussion. Guidance for IS scholars is provided on
how to conduct LRs that contribute to the cumulative knowledge development within
and across the IS field to best prepare the next generation of IS scholars.'

text: Multi-attribute value theory (MAVT)-based recommender systems have been proposed
for dealing with issues of existing recommender systems, such as the cold-start
problem and changing preferences. However, as we argue in this paper, existing
MAVT-based methods for measuring attribute importance weights do not fit the shopping
tasks for which recommender systems are typically used. These methods assume well-trained
decision makers who are willing to invest time and cognitive effort, and who are
familiar with the attributes describing the available alternatives and the ranges
of these attribute levels. Yet, recommender systems are most often used by consumers
who are usually not familiar with the available attributes and ranges and who
wish to save time and effort. Against this background, we develop a new method,
based on a product configuration process, which is tailored to the characteristics
of these particular decision makers. We empirically compare our method to SWING,
ranking-based conjoint analysis and TRADEOFF in a between-subjects laboratory
experiment with 153 participants. Results indicate that our proposed method performs
better than TRADEOFF and CONJOINT and at least as well as SWING in terms of recommendation
accuracy, better than SWING and TRADEOFF and at least as well as CONJOINT in terms
of cognitive load, and that participants were faster with our method than with
any other method. We conclude that our method is a promising option to help support
consumers' decision processes in e-commerce shopping tasks.

text: CAPTCHAs are challenge-response tests that aim at preventing unwanted machines,
including bots, from accessing web services while providing easy access for humans.
Recent advances in artificial-intelligence based attacks show that the level of
security provided by many state-of-the-art text-based CAPTCHAs is declining. At
the same time, techniques for distorting and obscuring the text, which are used
to maintain the level of security, make text-based CAPTCHAs diffcult to solve
for humans, and thereby further degrade usability. The need for developing alternative
types of CAPTCHAs which improve both, the current security and usability levels,
has been emphasized by several researchers. With this study, we contribute to
research through (1) the development of two new face recognition CAPTCHAs (Farett-Gender
and Farett-Gender&Age), (2) the security analysis of both procedures, and (3)
the provision of empirical evidence that one of the suggested CAPTCHAs (Farett-Gender)
is similar to Google's reCAPTCHA and better than KCAPTCHA concerning effectiveness
(error rates), superior to both regarding learnability and satisfaction but not
effciency.

text: Many academic disciplines - including information systems, computer science,
and operations management - face scheduling problems as important decision making
tasks. Since many scheduling problems are NP-hard in the strong sense, there is
a need for developing solution heuristics. For scheduling problems with setup
times on unrelated parallel machines, there is limited research on solution methods
and to the best of our knowledge, parallel computer architectures have not yet
been taken advantage of. We address this gap by proposing and implementing a new
solution heuristic and by testing different parallelization strategies. In our
computational experiments, we show that our heuristic calculates near-optimal
solutions even for large instances and that computing time can be reduced substantially
by our parallelization approach.

text: Cloud computing promises the flexible delivery of computing services in a
pay-as-you-go manner. It allows customers to easily scale their infrastructure
and save on the overall cost of operation. However Cloud service offerings can
only thrive if customers are satisfied with service performance. Allow-ing instantaneous
access and flexible scaling while maintaining the service levels and offering
competitive prices poses a significant challenge to Cloud Computing providers.
Furthermore services will remain available in the long run only if this business
generates a stable revenue stream. To address these challenges we introduce novel
policy-based service admission control mod-els that aim at maximizing the revenue
of Cloud providers while taking in-formational uncertainty regarding resource
requirements into account. Our evaluation shows that policy-based approaches statistically
significantly out-perform first come first serve approaches, which are still state
of the art. Furthermore the results give insights in how and to what extent uncertainty
has a negative impact on revenue.

text: The protection of information technology (IT) has become and is predicted
to remain a key economic challenge for organizations. While research on IT security
investment is fast growing, it lacks a theoretical basis for structuring research,
explaining economic-technological phenomena and guide future research. We address
this shortcoming by suggesting a new theoretical model emerging from a multi-theoretical
perspective adopt-ing the Resource-Based View and the Organizational Learning
Theory. The joint appli-cation of these theories allows to conceptualize in one
theoretical model the organiza-tional learning effects that occur when the protection
of organizational resources through IT security countermeasures develops over
time. We use this model of IT security invest-ments to synthesize findings of
a large body of literature and to derive research gaps. We also discuss managerial
implications of (closing) these gaps by providing practical ex-amples.

text: 'Nowadays, providing employees with failure-free access to various systems,
applications and services is a crucial factor for organizations? success as disturbances
potentially inhibit smooth workflows and thereby harm productivity. However, it
is a challenging task to assign access rights to employees? accounts within a
satisfying time frame. In addition, the management of multiple accounts and identities
can be very onerous and time consuming for the responsible administrator and therefore
expensive for the organization. In order to meet these challenges, firms decide
to invest in introducing an Identity and Access Management System (IAMS) that
supports the organization by using policies to assign permissions to accounts,
groups, and roles. In practice, since various versions of IAMSs exist, it is a
challenging task to decide upon introduction of an IAMS. The following study proposes
a first attempt of a decision support model for practitioners which considers
four alternatives: Introduction of an IAMS with Role-based Access Control RBAC)
or without and no introduction of IAMS again with or without RBAC. To underpin
the practical applicability of the proposed model, we parametrize and operationalize
it based on a real world use case using input from an expert interview.'

text: Literature reviews play an important role in the development of knowledge.
Yet, we observe a lack of theoretical underpinning of and epistemological insights
into how literature reviews can contribute to knowledge creation and have actually
contributed in the IS discipline. To address these theoretical and empirical research
gaps, we suggest a novel epistemological model of literature reviews. This model
allows us to align different contributions of literature reviews with their underlying
knowledge conversions - thereby building a bridge between the previously largely
unconnected fields of literature reviews and epistemology. We evaluate the appropriateness
of the model by conducting an empirical analysis of 173 IS literature reviews
which were published in 39 pertinent IS journals between 2000 and 2014. Based
on this analysis, we derive an epistemological taxonomy of IS literature reviews,
which complements previously suggested typologies.

text: Natural disasters, including earthquakes, Tsunamis, floods, hurricanes, and
volcanic eruptions, have caused tremendous harm and continue to threaten millions
of humans and various infrastructure capabilities each year. In their efforts
to take countermeasures against the threats posed by future natural disasters,
the United Nations formulated the ?Hyogo Framework for Action?, which aims at
assessing and reducing risk. This framework and a global review of disaster reduction
initiatives of the United Nations acknowledge the need for information systems
research contributions in addressing major challenges of natural disaster management.
In this paper, we provide a review of the literature with regard to how information
systems research has addressed risk assessment and reduction in natural disaster
management. Based on the review we identify research gaps that are centered around
the need for acquiring general knowledge on how to design IS artifacts for risk
assessment and reduction. In order to close these gaps in further research, we
develop a research agenda that follows the IS design science paradigm.
