*Editorial Introduction*

James Jiang


We have five articles in this issue and their topics are diverse. The first
article in this issue, by Kotusev, is entitled “Enterprise Architecture: A
Reconceptualization Is Needed”. This study conducts an extensive Enterprise
architecture (EA) literature review to describe the problems with the
current concept of EA, demonstrate the critical inconsistencies between
this concept and the real practice use of EA.

1)     *Enterprise Architecture: A Reconceptualization Is Needed*

Svyatoslav Kotusev



*Abstract*

Enterprise architecture (EA) is a description of an organization from an
integrated business and IT perspective. Current literature conceptualizes
EA as a comprehensive blueprint of an enterprise organized according to a
logical framework and describing its current state, desired future state
and migration roadmap. However, the current concept of EA originates from
non-empirical sources, lacks demonstrated examples of its successful
practical implementation and deviates from the real practical use of EA in
organizations in multiple important aspects. Due to these and other
problems the notion of EA needs to be reconceptualized in order to more
accurately reflect empirical realities. In this paper, based on an
extensive EA literature review, I describe the problems with the current
concept of EA, demonstrate the critical inconsistencies between this
concept and the real practice use of EA in organizations and illustrate
them based on a recent exemplary case study of a successful EA practice.
Although this paper justifies the need for the reconceptualization of EA
and points to the most essential aspects of this reconceptualization, it
does not offer an alternative ready-to-use conceptualization and represents
only the first step towards developing a new, evidence-based concept of EA.

2)     T*echnology Enabled Information Services Use in Tourism: An
Ethnographic Study of Chinese Backpackers*

Brad McKenna, Wenjie Cai, Tuure Tuunanen

*Abstract*

The purpose of this paper is to investigate the previously unexplored
theoretical relationship between technology enabled information services
(TEIS) and the value created by the use of such services. This paper
presents a mixed virtual and multi-sited ethnography to provide a thick
description of Chinese backpackers (CBs) use of TEIS. Participant
observations and interviews of CBs in three different journeys within
Europe were undertaken. Our findings illustrate that additional usage
values occur when TEIS are used in a tourism context. Social influences and
technical infrastructure play a stronger role than previous research
presented. The study contributes to the literature by 1) providing a
theoretical understanding of tourists’ TEIS use; 2) documenting a study of
a complete package of technologies used by CBs, and 3) proposing a research
model which can be used for studying different TEIS use behaviour/patterns,
and also in the design of TEIS for specific contexts.

3)    *Towards a Framework for Strategic Security Context in Information
Security Governance*

Sean B Maynard, Terrence Tan, Atif Ahmad, Tobias Ruighaver



*Abstract*

Information security governance influences the quality of strategic
decision-making to ensure that investments in security are effective.
Security governance involves a range of activities including adjusting
organizational structures, designating roles and responsibilities,
allocating resources, managing risks, measuring results, and gauging the
adequacy of audits and reviews. We identified three security issues in an
organization around strategic context in an in-depth and revelatory case
study. These are (1) limited diversity in decision-making; (2) lack of
guidance in corporate-level mission statements to security decision-makers;
(3) a bottom-up approach to security strategic context development. We
further argue that instead of an approach that is based on risk and
controls, organizations should address objectives and strategies through
developing depth in their security strategic context.

4)     *Is team cohesion a double edged sword for promoting innovation in
software development projects?*

Ashish Kakar, Adarsh kumar Kakar



*Abstract*

Creation of new knowledge in teams requires collaboration among its team
members. Although individual creativity is important, no single individual
possesses all the skills and knowledge necessary to deal with complexity in
knowledge work.  Therefore, team cohesion is considered a prerequisite in
innovation. However, in this study we argue that team cohesion could be a
double edged sword. It could even be detrimental to innovation at high
levels of team cohesion. The findings of this study with 56 software
projects quantitatively support this premise. These findings have useful
implications for practitioners engaged in knowledge work

5)     *Exploratory Analysis of Out-of-Hospital Days Based on Cancer
Patients in China*

Luwen Huangfu, Stephen Hayne, James Ma, Nicholas Roberts



*Abstract*

Cancer (re)admission time interval, or Out-of-Hospital Days (OHD) between
two consecutive hospital (re)admissions, is commonly considered as an
indicator of health service quality. Despite its importance, the risk
factors of OHD are largely unknown because of limited access to cancer
patients’ data and the lack of relevant characteristics (e.g., geographic
factors) in the data. To explore the association between patients’
conditions and readmission events, we analyze a sample of 22,231 admissions
(OHD>30), consisting of demographic, medical, and financial factors,
extracted from Electronic Health Records (EHR) of 635,261 cancer patients
from 190 hospitals in China. Geographic factors are also included by
applying text mining to the free-form address fields of patients’ homes and
hospitals. Using hierarchical linear regression, we find that various
factors significantly influence OHD: age, marital status, number of
admissions, and whether the treating hospital is in the same province as
the patient’s home address.
