Local Model of Crisis Management in Libraries of Iran's Research Centers (mixed research).
Introduction
Today crisis and crisis management are discussed in all knowledge
fields, and all scientists and managers of organizations believe that
prevention is more profitable and easier. However this is not seriously,
scientifically and practically posed and performed in the organizations
and it has remained just as a theory. Managers of organizations who have
tangibly understood damages of crises are seeking principles and models
in order to encounter with their potential and evident crises in their
organizations, because they know that all or most of their goals that
they proposed and plans which accomplished for reaching to those goals,
and also huge costs that are allocated to them are overridden and the
organization would face serious problems. Crisis management is posed in
different areas. As one of the main parts of society, organizations are
not exception. In libraries, crisis is a turmoil that has a fundamental
effect on the activities of libraries, administrative affairs, financial
affairs and reputation of library. This may be either
extra-organizational such as flood, fire and earthquake or
intra-organizational such as financial crises or unwillingness of
employees and/or outside reflection about intra-organizational
performance which is represented by failure in competition between
libraries or fundamental criticism about the performance of library.
Crisis management is an organized effort made by members of organization
with interested persons outside of organization in order to prevent
crisis or its effective management(Pearson and Clair, 1998, 61). Like
other micro-systems of social structure, crisis management system also
needs an objective, scientific and efficient model based on current
needs in order to reach its predicted goals more precisely and to
organize its plans. It is clear that the basis of such model should have
strong theoretical basis and principles. So, results of research should
be integrated with local conditions(environment, individuals, customers,
and their needs) so that to reach a comprehensive model. Crises that
organizations are faced with are classified to three main categories(1)
intra-organizational crises, (2) crisis in extra-organizational
environment, and (3) extra-organizational crises. It is possible that
these crises occur in the libraries of research centers, but because
there is no local model for performing crisis management in libraries,
it is not possible to provide integrity when facing damages raised by
crisis; this research therefore has studied localization of crisis
management in libraries of research centers respective to Iran's
Science, Research and Technology Ministry. Because these libraries have
critical role in the development of research process in the country and
their libraries are worthy resources of scientific, software and
hardware information. So if they have standard principles of crisis
management in their managerial regulations, they can prevent and control
natural and organizational crises effectively. To be aware of the most
important priorities in each stage of facing crisis in these libraries
and the most important measurements help to have a framework for facing
crisis and to manage crisis in them, which so far no framework has been
studied nor performed in the libraries of Iran. The importance of crisis
management in managerial process of libraries can be found in such
factors as frequency of crises, crisis scope, and effect of crises on
management and also its hidden effect on processes of libraries and
long-term and sometimes irreparable damages on body of the library. In
this research we study that how desired libraries to face with these
three crises and to provide a local model of crisis management.
Literature review
Mitroff and et al (2002) hold that in most of institutes top
managers do not accept that their institutes have encountered crisis
rather they deceive themselves and their addressees with some
justifications. They believe that critical thought is effective in
crisis management, and that the most important index that should be
regarded in model of crisis management is creating a critical
environment in an emotional atmosphere. Crisis acceptance by managers
and employees is the most principle that can help the organization when
it faces (pre, acute and post) crisis. In their research Rosenthal, Hart
and Charles(2003) have acquired a pattern which indicates the
performance of organization in every stage of crisis and provides a
scientific, thoughtful perspective for involved organizations. Present
research has used model of crisis management of American Federal
Emergency Management Agency(FEMA). Three stages of pre-crisis, acute and
post-crisis are considered as the basic framework of crisis management.
Represented model has emphasized on pre-crisis stage and the general
policy has focused on prevention and reduction of crisis. In acute
stage, decision-making dimension on crisis and its related aspects are
discussed. Psychology of crisis decision-making is also another subject
that is discussed in represented model. Uncertainty, despair, fear and
anxiety are considered as cases for decision-making. Accountability and
evaluation are regarded as two important activities for stages of
post-crisis. For Rosenthal and et al (2003) pre-crisis stage is the most
important stage and in their research they have found a model which
focused on prevention and reduction of crisis. This model has focused on
shortening of bureaucratic process and facilitating budget allocation
during crisis management. Researchers of this research hold that
bureaucracy in organizations would prevent right and on time crisis
management enforcement. In his research, Leechat (2005) has provided a
six-stage model for crisis management. He believes that the first step
is designing an organizational structure for crisis management. This
stage is followed by selecting a proper team. Then team is organized
through education and simulation of crisis-creation cases. Next stage is
designing a scenario for responding to crucial situation. When
comprehensive examining potential crisis-creation cases an appropriate
plan should be applied for regulating mentioned plan. In their research
Myer, Conte and Peterson (2007) have studied an evaluation model which
is broadly used while facing crisis to understand the effect of human
factors on a crisis. In this model which is an medical and triage
assessment system, features relating to the effect of crisis on
employees of an organization are discussed. Results of mentioned
research help organizations to manage the effect of crisis on their
employees. Van Leeuwen (2010) is represented a technique for ranking
possible risks in an organization. This technique is used in order to
identify potential manners of error in a process or a product of an
organization. The researcher has found that mentioned technique has
shortened quantitative analysis time and acted more precisely in
identifying crucial risks in organizations. So, using this technique is
highly effective while risk analysis and would increases its
effectiveness. In their mixed research, Lee, Yeung and Hong(2012) have
studied management of outsourcing risks. In this research the main goal
is compiling a general model for evaluation and simulation of
outsourcing risks in product and supplying chain of organizations. Risk
qualitative evaluation allows risk manager to visually represent and
explain imminent risks by using risk map. Monte Carlo's simulation
model in managing imminent outsourcing risks by the use of Milk-Run
system is used in this research. Results of this research showed that
order of outsourcing in new system causes decrease in average duration
consumed by customers and also reduction of total costs despite the
existence of risk and uncertainty. It is believed that framework of
management and risk evaluation can resolve uncertainty in operational
and administrative costs of organization and it causes trust making in
constant product chain in organization. According findings of Hoesseini
and et al (2012) studied organizations have been in average
situation(62.7 in strategic management and 52.2 in crisis management);
in represented model strategic management is regarded as the most
important index. By focus on "human resource management"
Ahmadi and et al (2012) have represented a crisis management model and
concluded that teamwork spirit, overcoming fear, central expertise and
devotion are among cultural factors that have many effects on crisis
management. Offering proper rewards to employees (average of 4.32) has
the most part in motivating human force to perform crisis management.
In a research Reklam (2013) has examined the effect of media on a
general conception of crisis. In his model "media and
networks" have the most effect on correct performance of crisis
management in the society and institutionalizing its related principles.
He believes that an organization should communicate a constant,
understandable and precise picture of crucial situation in order to
control crisis. Effective communications need broad intellectual
preparation. So it is necessary that employees have been sufficiently
educated. Mentioned cases can be clearly seen in researcher's final
model.
Research questions
--To determine how much ISO 31000 indexes and dimensions of
intra-organizational crisis management are observed in libraries of
studied research centers?
--To determine how much ISO 31000 indexes and dimensions of
extra-organizational operation environment crisis management are
observed in libraries of studied research centers?
--To determine how much ISO 31000 indexes and dimensions of
extra-organizational crisis management are observed in libraries of
studied research centers?
--To provide local model of crisis management in libraries of
studied research centers?
Research methodology
Research method is mixed method. In qualitative section and in
order to compile questions of questionnaire, grounded theory method and
in quantitative section survey analytics method was used. Grounded
theory is the process of compiled theorizing through collecting
organized data and their analysis for answering to modern questions of
research(Strauss and Corbin, 1998, 5). Results were collected by depth
semi-structured interviews and by using questionnaire, and they were
analyzed by inferential statistics. Research population composed of 38
director generals of crisis who were selected objectively based on more
employment record and higher education. Finally 12 persons were
interviewed that 2 latter interviews add no more new materials to
previous materials and reach saturation. Three types of codification
were used for analyzing data in qualitative section. Following interview
copying, open codification was carried out. In this part interviews were
read frequently line by line and they were broken down into separate
parts and every concept that came to mind was designated to important
sections. After concept extraction analyst put some of concepts into a
more abstract concept called "category". In central
codification, previously broken categories were dragged together in
order to show their relationship with categories and subcategories in a
new form. Researcher selects an open codification as the main category
or phenomenon and puts it in the center of the studied process, then
interconnects them to other categories. Other categories include such
concepts as casual conditions, medium conditions, grounded conditions,
strategies and finally consequences(Strauss and Corbin, 2010, 153-157).
This stage requires drawing a diagram called central paradigm. It shows
the relationship between mentioned concepts and main phenomenon.
Selective codification is the stage of consolidating and filtering the
categories. This stage explains localization process of crisis
management in libraries theoretically which it was performed through
writing the relationship between categories like a story. In this stage,
determination of main components composed research model is studied
which is shown in Fig. 1. In quantitative section population composes of
144 managers of desired research centers and libraries among them 112
persons filled the questionnaire that 80 persons were managers of
research centers and 32 persons of libraries.
In order to compile the questionnaire, grounded model represented
in Fig. 1 was used in which casual conditions, interventionists,
strategies, backgrounds and consequences are stated, and also indexes of
three extra-organizational crisis, intra/extra-organizational operation
environment, and also localization indexes in Iran were used.
Justifiability and consistency of questionnaire
Given that questionnaires of crisis management outside of Iran
could not be used in libraries of Iran, in interview process therefore,
critical indexes are added in the questionnaire. Results of this
questionnaire therefore are applied for gaining research goals. To
insure questions of questionnaire are related to variables posed in
hypotheses and research questions they were distributed between a few of
specialists in crisis management in addition that questionnaire was
reviewed by professors of librarianship and information science, then
vague and unrelated questions were distinguished and deleted. So, the
justifiability of research instrument was confirmed. In order to
determine the consistency, questionnaire was(randomly) distributed
between 12 managers of desired research centers and libraries to carry
out pretest, and then its reliability was measured by computing
Cronbah's alpha coefficient. Results of measurement of
Cronbach's alpha of subset dimensions of three separate crises have
been computed.
Given to results represented in table 1. Cronbach's alpha
coefficient of all dimensions of either type of crisis management is
equal or higher than 70%; so consistency of questionnaire has been
confirmed.
Research Findings
Average, mean, exponent and standard deviation indexes were used to
describe data, and factor analysis, path analysis and goodness of fit
indexes were used to analysis data. Following results are gained for
answering to first question of research: "how much ISO 31000
indexes and dimensions of intra-organizational crisis management are
observed in libraries of the studied research centers?":

Given to obtained results in table 2. The lowest score of
intra-organizational crisis is 112 and the maximum is 222 and change
range is 110 and the maximum of repeated score is 134. Score of half of
respondents is equal or lower than 146 and half of them is more than it.
Average score of statistical sample equals with 149. So, for total
evaluation of intra-organizational crisis management it should be
acknowledged that distribution of this variable and
"personal", "motivational opportunities",
"managerial", "regulations" and "safety
predictions" variables tends to normal distribution and in
answering to first question it should be said that intra-organizational
crisis management dimensions are averagely observed in desired
libraries. In answering to second question of research "how much
ISO 3100 indexes and dimensions of crisis management of
extra-organizational operation environment are observed in libraries of
the studied research centers?" following results are obtained:

Given to table 3 the lowest score for crisis management of
extra-organizational operation environment is 44 and the maximum is 98
that changes range is 54 and the highest repeated score is 67 and score
of half of respondents is equal or lower than 70 and half of them is
more than it and average score of statistical sample is 70. So, in total
evaluation of crisis management of extra-organizational operation
environment it can be said that distribution of this variable and
"IT", "budgeting", and "organizational
communications" dimensions tend to normal distribution. In
answering to second question, therefore, it can be acknowledged that
dimensions of crisis management of extra-organizational operation
environment are averagely observed in libraries of research-centers. In
order to answer to third question" how much ISO 31000 indexes and
dimensions of crisis management of extra-organizational operation
environment are observed in libraries of the studied research centers?
"following results are obtained.
Given to table 4, the lowest score for extra-organizational crisis
is 30 and the maximum is 80 and changes range is 50 and the highest
repeated score is 51 and score of half of respondents is equal or lower
than 48 and half of them is more than it. Average score of statistical
sample is 49. In total evaluation of extra-organizational crisis
management variable it should be acknowledged that distribution of this
variable and dimensions of "political and economic issues of
society", "building and equipment" tends to normal
distribution, and in answering to third question of research it can be
said that extra-organizational crisis management dimension in the
studied libraries is averagely observed. In order to answer to last
question" what is local model of crisis management in libraries of
the studied research centers?" two models are represented by using
path analysis method and also by the use of measuring indexes relating
to goodness of fit and measurement errors(Tucker-Lewis non-normed fit
index), Bentler-Bonett index(normed fit index), Hoelter index, root mean
square error of approximation which are studied at below:
Local models of crisis management in libraries of desired research
centers
In this research, first model shows relationship between
intra-organizational crisis management(independent variable) and
extra-organizational crisis management(dependent variable) and second
model shows relationship between intra-organizational crisis
management(independent variable) and extra-organizational operation
environment crisis management(dependent variable).
Fig. 2 shows the model of relationship between dimensions of
intra-organizational crisis management including "personal
dimension", "motivational opportunities dimension",
"managerial dimension", "regulations dimension",
"saftey predictions dimension", and "specialized
activities dimension" as independent variable and
extra-organizational including "building and equipments",
"political and economic issues" as dependent variable.[lambda]
rate(loading or effect) of hidden external variable of
intra-organizational crisis management includes "personal
dimension" 0.53, "motivational opportunities dimension"
0.86, "managerial dimension" 0.73, "regulations
dimension" 0.82, "saftey perdictions dimension" 0.60, and
"specialized activities dimension" 0.57 which all of them form
intra-organizational crisis management and totally its effective
coefficient is 75%(these indexes covered 75% of changes in dependent
variable of extra-organizational crisis management). "Motivational
opportunities dimension" shows the highest intensity and
"personal dimension" has the lowest intensity. These two
variables have direct relation, and as dimensions of
intra-organizational crises increase dimensions of extra-organizational
crises management also increase and vis versa. "motivational
opportunities" has the most effect on "building and equipmemts
dimension". [lambda] rate includes "building and equipments
dimension" 0.91, "political and economic issues of
society" 0.56 that all of these indexes form extra-organizatonal
crisis management. "goodness of fit index" is 0.91, so this
model has acceptable fit with reality. Obtained coeffient rate indicates
direct effect of inrta-organizational crisis management on
extra-organizational crisis management.
Given to table 5. on one hand five goodness of fit indexes and
fitness of model No.1 and experimental data on the other are confirmed.
Therefore a desirable match between structured model and experimental
data has been provided. Model No. 1 is completely fit because
Tucker-Lweis non-normed fit index (0.90) and Benterl-Bonett normed fit
(0.90) are equal 0.90. Hoelter index (0.71) is more than 0.70 which
indicates desirable fit.
Fig. 3 shows model of relationship between dimensions of
intra-organizational crisis management including "personal
dimension", "motivational opportunities dimension",
managerial dimension", "regulations dimension",
"saftey perdictions dimension", specialized activities
dimension", as independent variables and dimensions of
extra-organizational operation environment cricis including "IT
dimension", "bodgeting dimension", "organizational
communications dimension" as dependent variables. 1 rate(loading or
effect rate) is extra-hidden variable of dimensions of
intra-organizational crisis management including "personal
dimesion" 0.49, "motivational opportunities dimension"
0.83, "managerial dimension" 0.72, "regulations
dimension" 0.78, "safety predictions dimension" 0.67,
specialized activities dimension" 0.65 that all of these indexes
form intra-organizational crisis management variable and generally it
has -0.81 effective coefficient^ set of these indexes covers b1% of
changes of dependent variable of operation environment crises).
"Motivational opportunities dimension" and "personal
dimension" show the most and the lowest intensity respectively. Two
variables have inverse relationship; and as dimensions of
intra-organizational crisis increase, crises of extra-organizational
operation environment decrease.
[lambda] rate is intra-hidden variable for crises of
extra-organizational operation environment including "IT
Technology" 0.23, "budgeting dimension" -0.91,
"organizational relationship dimension" -.49 that all of these
indexes form crises of extra-organizational operation environment.
"goodness of fit index" of this model is 0.92, so this model
has an acceptable fit with reality. Obtained coefficient indicates the
inverse effect of intra-organizational crisis management on crisis
management of extra-organizational operation environment. This model
indicates "motivational opportunities" and
"regulations" dimensions in intra-organizational crisis
management have the most effect on "budgeting dimension" in
crisis management of extra-organizational operation environment.
Given to table 6, five goodness fit indexes and fit of model 2 on
one hand and experimental data on the other are confirmed. So a
desirable match has been provided between structured model and
experimental data, and desirable fit represents modeling of structural
equations regarding to the effect of intra-organizational crisis
management on crisis management of extra-organizational operation
environment. Suggested model No. 2 is completely fit because
Tucker-Lewis non-normed fit index (0.91) and Bentler-Bonett normed fit
index(0.91) are more than 0.90 and Hoelter index(0.71) is more than
0.70.
Conclusion
Present research studied how libraries of research centers
dependent on Science, Researches and Technology Ministry can face with
three intra-organizational, extra-organizational and
extra-organizational operation environment crises, then two local models
are represented. Each of these three types of crises management has
different dimensions that results show subset dimensions of all three
categories of crisis management are averagely observed in desired
libraries. First model indicates the direct relationship between
intra-organizational crisis management and extra-organizational crisis
management; and "motivational opportunities have the most effect on
"building and equipment". As in model provided in Ahmadi and
et al(2012) research it is emphasized on motivating employees in order
to perform crisis management. Second model shows inverse relationship
between intra-organizational crisis management(independent variable) and
crisis management of extra-organizational operation
environment(dependent variable). This model indicates that as
"motivational opportunities" and "regulations"
dimensions increase "budgeting dimension" decrease. It is also
seen in the results of Rosenthal and et al (2003) research that
bureaucracy has inverse effect on crisis management process and it
impairs cost supply and correct budgeting process in all stages of
crisis. Given to results of present research it is recommended that
managers of desired libraries to include local principles and models of
crisis management in their codes, and to prevent and control natural and
organizational crises and motivate their employees to perform it.
Providing proper situations for using technology and resolving related
problems, convincing managers of research centers to allocate proper and
separate budget to crisis management, pursuing and examining all natural
and organizational crises with which library has been encountered during
last decade, and using resulted experiments in new policy-making of
library are other cases that is better to be observed by managers of
libraries.
