Production and procurement strategies for seasonal product supply chain under yield uncertainty with commitment-option contracts
استراتژی های تولید و تهیه زنجیره تامین محصول فصلی تحت عدم اطمینان محصول با قراردادهای قرارداد تعهدی-2017 This paper develops a game-theoretic decision-making model of production and procurement with commit
ment-option contracts in a decentralized supply chain consisting of one manufacturer and one retailer. The
manufacturer distributes one kind of seasonal product via the retailer to the end market, whose demand is
random, and the manufacturers production yield is stochastic. We study the retailers optimal ordering policy
and the manufacturers optimal production strategy under two different option contracts (that is, commitment
unidirectional call option contract and commitment-bidirectional option contract). The effects of demand
uncertainty, production yield stochastic volatility, instant procurement price variability, and the price
parameters’ changes of option contracts on the optimal operational strategies and performances of both
participants are also analyzed. These results will be helpful for the manufacturers and retailers in the supply
chain with seasonal products to make production scheduling strategy and procurement policy feasibly and
scientifically.

“I just googled and read everything”: Exploring breast cancer survivors’ use of the internet to find information on complementary medicine
من همه چیو از گوگل میخام : تحقیق استفاده از بازماندگان سرطان سینه به اینترنت برای پیدا کردن اطلاعات در مورد پزشکی مکمل-2017 Objective: Breast cancer survivors often turn to the internet as an information resource when deciding whether to
use complementary and alternative medicine (CAM) but their use of online CAM-related resources is poorly
understood. The objective was to explore breast cancer survivors’ use of the internet when making decisions
about CAM use.
Design: A purposive sample of 11 breast cancer survivors (mean age = 56) completed a quantitative ques
tionnaire and a qualitative telephone interview. The theory of planned behaviour (TPB) was used to guide
interview questions. Framework analysis and descriptive statistics were used.
Setting: United Kingdom.
Results: All participants found information on CAM using the internet and used some form of CAM after their
diagnosis. Themes from the interviews went beyond the standard definitions of the TPB areas. Despite the lack of
approval from their social network and healthcare team, participants used the internet to find information on
CAM. Further, participants’ cancer diagnosis changed their needs, transforming how they perceived and ex
perienced the internet
Conclusions: Participants’ use of the internet was more complex than can easily be explained by the TPB and was
inherently connected to the experience of self-management for the consequences of cancer and its treatment. As
breast cancer survivors may not disclose their use of the internet to their healthcare team, healthcare profes
sionals need to be aware that the information available on the internet plays a factor in the decision-making
process to use CAM.

The fuzzy multi-objective distribution planner for a green meat supply chain
برنامه ریزی توزیع چند منظوره فازی برای یک زنجیره تامین گوشت سبز-2017 It is often a complex task for developing a product distribution plan of a supply chain (SC) network and a
supportive decision tool can be useful for easing the role of decision-making. On the other hand, it has been
increasingly becoming a demand to design a supply chain network considering the environmental impact as a
new dimension as required by authorities in many countries. This paper describes a development of a product
distribution planner for a three-echelon green meat supply chain (MSC) design in terms of issues including
numbers and locations of facilities that should be opened in association with the product quantity flows. These
issues were formulated into a fuzzy multi-objective programming model (FMOPM) with an aim to minimize the
total cost of transportation and implementation, the amount of CO2 emissions in transportation and the
distribution time of products from farms to abattoirs and from abattoirs to retailers, and maximize the average
delivery rate in satisfying product quantity as requested by abattoirs and retailers. To optimize the four
objectives simultaneously, three solution methods were investigated and used; which are the LP-metrics
method, the ε-constraint method and the goal programming method. The best solution was determined using
the Max-Min method by comparing the obtained Pareto solutions. A case study was examined based on the
developed model that demonstrates its applicability in making an optimal product distribution plan in trade-offs
among the four objectives.

Coordination of social responsibility and order quantity in a two-echelon supply chain: A collaborative decision-making perspective
هماهنگی مسئولیت اجتماعی و میزان سفارش در یک زنجیره تامین دو مرحله ای: یک دیدگاه تصمیم گیری مشترک-2017 Regarding globalization growing trend and sustainability concerns, the need for paying attention to the issues of
corporate social responsibility (CSR) not only applies to individual firms, but also extends to the whole supply
chain (SC) networks. Assisting CSR issues in one individual firm will thoroughly influence other supply chain
members. In this paper, a supplier-retailer SC is considered in a newsvendor setting. It is possible for the
supplier to invest in CSR activities which could improve the popularity of products and, subsequently, market
demand. Firstly, both members decisions under decentralized and centralized decision-making models are
investigated; afterwards, a novel collaborative model is proposed to determine optimal order quantity and CSR
investment, thus maximizing the whole SC profits and also motivating members to participate. Finally, the
results of decentralized, centralized, and collaborative models are compared and some managerial insights are
provided. Numerical experiments indicate that, under some circumstances, alongside the increment of SC
profits, more CSR investment and better CSR performance level will be achieved through the collaborative
model than other decision-making structures.

Assessment of supply chain integration and performance relationships: A meta-analytic investigation of the literature
ارزیابی تجمیع زنجیره تامین و روابط عملکرد: تحقیق متاآنالیز از ادبیات-2017 The concept of integration has received considerable attention in operations and supply chain management
literature in a time spanning over two decades. To advance theory development, it is important to critically
examine the empirical findings in various integration studies. This paper undertakes an extensive investigation
of the relationships between supply chain integration and various performance dimensions using a meta
analytical methodology. The study contributes to literature in four important ways. First, the findings
empirically show that internal integration, supplier integration, and customer integration have significant
impact on a firms financial performance. Second, the study examines the impact of internal integration,
supplier integration, and customer integration on a firms operational performance; and its underlying
dimensions of cost, quality, delivery, and flexibility separately. Third, the study points out the specific
relationships between supply chain integration and performance that need to be further examined within
contingency framework to discern the role of moderating factors. Finally, to provide direction for managerial
decision-making, the study offers insights regarding integration dimension(s) that have largest breadth and
depth of impact on various performance measures.

From metaphorical information overflow and overload to real stress: Theoretical background, empirical findings, and applications
از سرریز اطلاعات استعاری و اضافه بار به استرس واقعی: زمینه نظری، یافته های تجربی و برنامه های کاربردی-2017 The paper presents the reader with a psychological analysis of one of the results of the global phe
nomenon of information overflow and how it translates into an observable psychological outcome, in
formation stress, thus hindering the process of decision-making. Both, the anchoring in the broader
context of civilizational changes and, in the particular, in the field of psychology, especially individual
differences and stress psychology, are provided, followed by a series of results of our own investigations
of managers and emerging adults (entering the job market). Particularly, self-control and the styles of
thinking are presented as correlates of increased infostress. We then explore the implications these
results might have for the selection and training of managers.

Make it personal: A social explanation system applied to group recommendations
آن را به شخصی کن: یک سیستم تبیین اجتماعی اعمال شده به توصیه های گروه-2017 Recommender systems help users to identify which items from a variety of choices best match their
needs and preferences. In this context, explanations act as complementary information that can help
users to better comprehend the system’s output and to encourage goals such as trust, confidence in
decision-making or utility. In this paper we propose a Personalized Social Individual Explanation approach
(PSIE). Unlike other expert systems the PSIE proposal novelly includes explanations about the system’s
group recommendation and explanations about the group’s social reality with the goal of inducing a pos
itive reaction that leads to a better perception of the received group recommendations. Among other
challenges, we uncover a special need to focus on “tactful” explanations when addressing users’ personal
relationships within a group and to focus on personalized reassuring explanations that encourage users to
accept the presented recommendations. Besides, the resulting intelligent system significatively increases
users’ intent (likelihood) to follow the recommendations, users’ satisfaction and the system’s efficiency and
trustworthiness.

Challenges in IT security preparedness exercises: A case study
چالش های تمرین آمادگی برای امنیت اطلاعات: یک مطالعه موردی-2017 The electric power industry is currently implementing major technological changes in order
to achieve the goal of smart grids. However, these changes are expected to increase the sus
ceptibility of the industry to IT security incidents. IT security preparedness exercises are
not commonly performed in the electric power industry, even though this industry is con
sidered part of society’s critical infrastructure. Resolving an IT security incident requires
inter-departmental collaborations between various categories of personnel, and to success
fully achieve this, training is required. The process of preparing a response to incidents
enhances the nature of collaboration, coordination, and communication within an organi
zation. Our objective is to understand the challenges faced when performing IT security
preparedness exercises, as challenges experienced during these exercises affect the re
sponse process during a real incident. By improving the exercises, the response capabilities
would be strengthened accordingly. We have designed a multiple-case study with six teams
in three organizations. We collected data by performing semi-structured interviews, par
ticipant observations, and from process artifacts. We identified six main challenges involving
team composition and external expert involvement, goal definition, documentation, and time
management. In summary, there are many ways of conducting preparedness exercises.There
fore, organizations need to both optimize current exercise practices and experiment with
new ones in order to ensure continuous learning and improvement; hence, they can be ad
equately prepared to respond to IT security incidents.

Empirical assessment of the competitive conduct of Nigerian banks in a post-consolidation era
ارزیابی تجربی از رفتار رقابتی بانک های نیجریه در دوران پس از تثبیت-2017 This paper is an empirical assessment of the level of competition in the Nigerian banking industry
following the consolidation exercise, using a bank-level panel data, for the period 2005–2014.
Empirical evidence from the Panzar and Rosse (1987) H-statistic reveals that market power in the
Nigerian banking industry is consistent with monopolistic competition, which implies that firms
are independent in their decision-making and conduct. This study innovates by incorporating
non-interest income accounts in the assessment of revenue, and findings suggest that bank
competitiveness decreases as revenue tends toward an inclusion of non-interest income or fee
based services.
