Social Network Analysis - The Situation of the Homeless in San Francisco

Problem: Homeless People in San Francisco

Remark: Sociologists and Researchers differenciate between the terms “homeless” and “chronically homeless”. Furthermore there are two dimensions of homelessness – long-term ( and near-tearm (six month)  homelessness.
Background:

Although visible and widespread homelessness emerged unexpectedly in San Francisco in 1982, its causes are not a mystery. Events that occurred in the preceding decade are:
  • The San Francisco Redevelopment Agency destroyed thousands of low-cost single room occupancy hotels in the South of Market for "urban renewal."
  • The City's Rehabilitation Assistance program (RAP) forced thousands of low-income tenants to leave the upper Haight-Ashbury, initiating a gentrification process that would virtually eliminate privately owned low-cost housing in the neighborhood.
  • The City's Planning Department reported that over 6,000 single room occupancy units were lost from 1975-79, and another 1,700 from 1981-88.
  • Rapidly increasing real estate values led to significant increases in rent citywide and displacement of low-income tenants through neighborhood gentrification.
  • The statewide mental health system steadily declined and board-and-care homes were converted to market-rate homes, rental housing, or condominiums.
  • The federal government responded to these events, which also occurred in similar forms throughout America's major cities, by sharply reducing the availability of subsidized housing. Thus, as the gap between people's incomes and housing costs widened, federal housing policy failed to intervene to prevent rising homelessness.

Idea | How can SNA help with this problem?
The idea is to create an efficient and low-cost opportunity to identify,  interact, integrate and (re)-incorporate homeless people who are out on the streets of San Francisco into the community and society while meticulously keeping track of the homeless population to better react in case of incidence, to provide help and assistance (medical treatments, social work, insurance etc.) and setting up strategies  to minimize the expenses of the City of San Francisco (especially because the city is receiving federal funds for homelessness form the U.S Department of Housing and Urban Development - It costs  $87 per day to incarcerate someone in the county jail - but it costs only $28 per day to shelter them ).

The idea is to develop a reliable system for use by the city, non-profits and interested parties to track the use of homeless services such as med treatments for drug and acohol addicts, shelter space, etc.
“Sitting or lying on the sidewalk can result in a ticket. There are few public restrooms, but urinating on the street can result in a ticket. There are no showers, but anyone caught washing up in the library bathroom could be banned from the premises. Sleeping in a park overnight is illegal.” - (Source: http://www.sfbg.com/2014/03/25/san-franciscos-untouchables?page=0,1)
Moreover, the next step would be to develop an app which would help the homeless people (yes, they do have phones!) to get an overview of any related information homeless people need. (e.g free and upcoming events for museums, public lectures, sports; opening hours for med treatments; stores or locations where organizations give away second-hand/used cloth, about free laundry places, places which give away food, where homeless can find legal support, free pre-school/daycare for children of homeless parents etc.)

Why? Because I believe that although people are homeless, the society should still try to find ways to care about every human. No human at all should be without a place called home. Homeless people are often treated as humans of the third class, they are the lowest link within the chain of social status, even after immigrants. Amongst other factors, homelessness is not always an outcome of personal difficulties, but also an outcome of social neglection. If the society and all people , procedures and processes in place/charge did not counteracted those two reasons before the homeless situation occurred, they should offer help now.

Network Data Collection - What data do you need?

Finding data for the challenge is not a very difficult. Non-Profit-Organizations, the City of San Francisco and the local newspapers are pretty well organized when it comes to data collection in the past years.

For compiling up-to-date data volunteers could go out on the streets – labeled as such to show seriosity and provide at least little safety for the people volunteering, e.g mobile phones could be carried by each volunteer to ease communication between the helpers and function as a safety tool – and collectively find and interview homeless about their race, name, age, maritial status, heritage (birth certificates if legal due to data privacy and security), family members, cause of homelessness and most common places they live and hang out on the streets.

Additionally, a personal network survey could be designed similar to a survey which was conducted by Clyde Mitchell among homeless women and decribed in Social Networks in 1987. 
(Source: Mitchell JC. The components of strong ties among homeless women. Social Networks. 1987;9(1):37–47) 
This type of survey has four modules. First, the homeless will provide information about themselves such as age and gender. In this module, additional information on drug use and drinking/sexual behaviours and attitudes  will be collected, providing the necessary non-structural variables. Second, the homeless will provide information with a list of 20 network members, following standard personal network data collection methods, which have shown that 20 alters is adequate to assess the variability in network structure and composition.
To address ethical concerns associated with the ability to identify those who appear as secondary participants via the profiles the homeless provided in the social network section of our survey, the data can be only consistent of the first names and the first letter of the last name for the 20 adult network members.
In the third survey section, the homeless will provide information about their network members, including but not limited to demographics, provision of social support and the respondent’s perceptions of the network members’ engagement in substance use and risky drinking/sexual behaviours. In the final module, a homeless reports his perception of the level of interaction among his network members. The third and fourth modules will provide data we use calculate social network composition and fragmentation, respectively.

Furthermore, the volunteers could check the data against with the cities registry offices, the San Francisco Homeless Count & Survey plus any other records such as studies from the National Law Center on Homeless and Poverty, the FBI, the California Department of Justice etc. provided by research groups or faculties of San Francisco’s universities such as the “California’s New Vagrancy Laws: The Growing Enactment and Enforcement of Anti-Homeless Laws in the Golden State”. (Source: http://papers.ssrn.com/sol3/papers.cfm?abstract_id=2558944)

Further Questions

·      What are the specifics of homeless and chronically homeless people?
·      Is there any homelessness transition from near-term to long-term homelessness?

What will be the most important network measures?

Network Fragmentation:
The number of network members who were unconnected to respondent’s other alters (isolates), the number of small groups of two (dyads) and the number of groups of three or more network members (components greater/equal 3), because high numbers of isolates and dyads, plus low numbers of groups of any size larger than 2 indicate network fragmentation.
Across all network members and within subgroups of network members thought to drink alcohol to intoxication, use drugs, have risky sex etc.
Social Network Composition:
Because all respondents will report 20 network members and because it is interesting to see the overall impact of the number of network members who are proactive and risky, the SNA will be able to compare the count of network members who were reported to have specific characteristics or were reported to have been met in particular social environments: to indentify support available in men’s and women’s networks, the number of family members, sex partners and other homeless individuals in the network will be counted.
To gauge proactive peers, the number of alters thought to be “responsible”, who “cared for the respondent” and who would “provide assistance” to the respondent “no matter what” will be counted.
Subgroups:
Indentification of clusters to see among whom there are realtively strong, direct, intense an/or positive ties”.
Hypothesis: Significant differences between women and men groups
Questions: Are there specific race-related subgroups?
Density Measures:
Is the density higher than one or 0? Are the homeless well committed? How many people do they know amongst themselves? Who do they stick to?
Closeness Centrality:
Useful measure because the concept of homeless people in SF does not require direct ties. Measurement of indepence form control of others.

 Analysis


In terms of near-term homelessness, being continuously homeless may be associated with increased exposure to high-risk individuals and decreased exposure to protective or supportive individuals. Specifically continuous, near-term homelessness will be associated with greater proportions of risky network members like drug users and sexual risk takers, and lesser proportions of supportive network members like family. Further, we propose that because the people e.g. a homeless man interacts with changes rapidly while they are on the street, chronic homelessness is more strongly associated with network structure than it is with network composition
(Source: Calsyn RJ, Morse GA. Predicting chronic homelessness. Urban Affairs Review. 1991;27(1):155–164) 
So, for example men who are chronically homeless will have more fragmented networks than those not chronically homeless, as evidenced by more isolated network members (isolates) and groups of two (dyads) and fewer groups of three or more in the networks of chronically homeless men, both overall and among risky subgroups of their networks.

Social Network Analysis for Social Aspect


Vision:
In tough times like losing a loved one, SNA could be beneficial in trying to contact people with an important message. It could be tough to find people that the person was in contact with that would want to attend the funeral. I know from personal experience that trying to find out who my father was in contacted with from his past life was difficult for my mom. We all knew that he knew some people across the nation but he didn't talk much about them. There could be issues like privacy but of course consent must be given in order to do such analysis. It would make things easier to arrange funeral dates to accommodate anyone who wants to attend. 

SNA:
Social Network Analysis measures the social structures of an individual (in my case) and sees what the connection is. Of course finding that individual's egonet is a great first step. Is it one sided? How is the closeness or betweeness (how much contact between them two or more?) These are just some of the questions that SNA could answer and find out whether or not if some of these connections are important or not. Even if someone doesn't know that person but somehow was influenced by his works could possible want to pay their respect. SNA could find these connections and expose such influence or lives that have been touched by them. It would be such a warm feeling for the family of the lost one to see the impact the person has made. 

SNA Complications:
Some of the complications we had in class would also be some of the problems doing this type of analysis. Problems like what type of data to use, does it start to invade others' privacy that are connected to that person, what qualifies as a strong connection, what makes that connection important or is it just business, or even just one sided. This going to be a long and extensive analysis to get it right or will take a long time to get the right/more information needed. The grieving family might not want to be hassle with this. No matter if all the information could be accessed, there still could be some personal information that can't be accessed and only certain people know. 

SNA Recommendations:
-I would say use data from all aspect of communication like social media or in their professional network. When I mean social media I mean all forms like Twitter or Instagram and combining the date to see if some connection is more than online presence. Also email can play a big part of the analysis as well. This could help in deciding who was just only a FaceBook friend, suppose to a friend in real life. Something as big as losing a loved one is pretty important for everyone that is connected to that person instead of finding out on your own. 

-Centrality measures will play a key part of the analysis. First, is just the immediate connection from that person. The 1st degree, closeness, betweeness, and even the eigenvector all play an important role in deciding whether or not to send a message to these connections. The more information we know about the connection, the better. As for the second connections, it gets a little more complicated. More information is needed on this analysis like how was he or she impacted indirectly from this person. Even though they might not have a direct connection with the person that died, they still might have been impacted greatly by that person and want to pay their respects. It can also help the grieving family to see that the life that was lost meant more than a family member. 

-Patience is key and important to this analysis on both sides: the team who is analyzing the data and the family wanting to send the message through his connections. It is going to be a lot of work and time is a key factor. It depends whether the family wants on how long to wait. I propose that the family decides on the time frame whether if it's 1 week or 2 weeks of analysis. Some might want to get the service done as quickly as possible or take the time to see who could attend the funeral. 

Conclusion:
Overall, I think SNA could be used in many different ways. This is just one way to ease the process of getting a message out to the people who really cared or touched by this person. There are a lot of variables that could happen or just by assuming that the connection means something more. The most important thing though is to get the message out and to decipher something complicated. It is a tool to see beyond something more than social media and professional connections. I believe it could work wonders with this kind of event. 

Using SNA to Find Homes For the Orphans

Using SNA to Find Homes For the Orphans


Background

I started volunteering in an orphanage in my hometown, Nanjing, in China back when I was still in high school. Although the care workers and we volunteers tried our best to make the kids feel like home there but at heart we know that the orphanage just cannot be home to every child. Moreover, after having volunteered there as a care worker for toddlers and children of pre-school age for some time, it was not hard to find out that the orphanage did not have the resources to fully develop the children’s potential, be it physical or intellectual, even though it is fully supported by the local government as well as a number of charities. That is why each time a child is adopted by a family, we would all feel happy for the child. Although we would miss those who left the orphanage but we know that living in a normal family and having a real home would be the best option for them. Therefore, the orphanage always hoped for more couples or families that meet the requirements for adoption to visit the orphanage and become foster parents/families later on. However, the orphanage acts passively in the entire process: those who would like to adopt a child will need to contact one of the partnering charities first and schedule an appointment with the orphanage through the charities for a visit. The procedures are especially complex when potential foster parents/families are from a foreign country.

Why is SNA relevant (and helpful) and how?

To be more actively engaged in creating a bigger chance in finding matched foster families for the children, the orphanage will need to reach out to more people who are qualified both within China as well as around the world to create. Social Network Analysis (SNA) provides an efficient and effective way to get in contact with potential adopters through the network of existing foster families and partnering charities.

In order to gather data for SNA, surveys will be used for compiling both the network data and the attribute data. Surveys will be distributed to the target audience through partnering charities. The survey will ask for names and contact information for those who answered. The key survey question for the network data will be:

“How often have you turned to the charity or someone whom you know (please leave her/his name) for information on becoming a foster parent?
1. Not at all (I have never thought about it);
2. Sometimes (I have friends who have adopted children and I want to learn more about it);
3. Often (I’m interested in becoming a foster parent and need more information about the adoption process);
4. Very often (I decide to become a foster parent and need to understand the adoption procedure clearly).”

The attributes will include: gender, age group, marital status, number of children, annual income, country of residence, have friends who are foster parents, etc.

To prepare for the network analysis, the valued network data will be dichotomized into zero being 1 and one being >= 2. The attribute data will be incorporated into the visualization and analysis of the network data.

For this network analysis, Node Centrality Measures contain more relevant information than Whole-Network. The “influencer”, which is the person who plays the role of a “promoter” of becoming a foster parent, can be identified by:
  • High Degree (total number of connections)
  • High OutDegree (mostly spreads information to others)
  • Medium to high Betweenness (important connector between nodes)


The potential candidates of a foster parent can be identified by:
  • High InDegree (mostly seeks information from others)
  • High Eigenvector (connects to “influencers”)


Important identifiers for the potential candidates will also include some of the attributes. Finding the ideal combination of attributes like “Age group”, “marital status”, “number of children”, “annual income” and “Have friends who are foster parents” along with the centrality measures will help us locate matched candidates and hopefully future foster parents.

Such a network analysis benefits both the orphanage and the partnering charities.
  • For the orphanage: Instead of communicating only through a partnering charity and wait for a delayed response, the orphanage is able to connect with her/him directly, respond to the candidate in time, schedule appointments for a visit and play an active role in starting a new adoption process at a later stage.
  • For the partnering charities: they have more information about their regular contacts regarding their knowledge in becoming a foster parent. They can invite the “influencers” to be volunteers for adoption-related events.

Keeping employees connected and up to date

Before coming to Hult I was working in an IT company in Turkey. There were approximately 200 people working in the headquarters including me. The company was providing IT services to customers, developing projects, training customers and outsourcing people to customers with specific needs. To be specific my company had two main branches, the IT services and training services. Besides our jobs our performance reports was also based on how well we trained ourselves. For instance during a quarter we should have publish certain number of webcasts and articles in company. Attend training sessions, and train people if you are qualified. Our company arranged training sessions on different areas of IT that everyone can attend. To be honest it never proceeded smoothly. Now I can see that with SNA it could have been done better.

There were several problems when trying to keep people up to date.

There were a lot of different departments. For instance we were software testing department, there were business analysts, developers such as web developers, graphic designers etc. There were a lot of people with different expertise that everybody can learn something from everyone. The problem was that people were not connected enough. Even if we connected not everyone has time to train other people on their regular day, so human resources were arranging a training sessions. They were trying to assess the supply and demand of a certain subject within the organization but they were not very good at it. About connection issue even though not everyone personally connected, there was healthy e-mail traffic within organization. It was easy to reach someone or everyone via e-mail. So it was easy to collect information within organization therefore information gathering was not a problem.

The problem is that it was not easy to train people. Even if you provide the training session if trainer and the trainee are not connected within the organization the trainee cannot truly improve himself on that subject. It is important for the company to have people with decent knowledge because of they were potential outsources.
SNA could be used to connect people, increase efficiency of trainings, and create a development program for employees.

So my solution is as follows.

1-    HR should determine the experience level of people such as experience in their field and their training experience. Sometimes not all people with knowledge are good trainers at the same time there are people that have trainer skills but without any expertise. Hence it is very important to train the trainer first. Trainers not only used within the company, generally they give training to customers too. It was important for company to have qualified trainers.
2-    HR should also determine that people demand which trainings and are there people to supply them. Sometimes there may be people to supply certain training but there may not be enough demand. But people may demand something close or related to it so it is possible to create the required demand.
3-    The last step is the connectivity among employees. Because of the e-mail traffic it is easy to determine the connectivity among people via a survey, like we did in the beginning of the class. For instance if trainer and trainee is connected it is easier for them to collaborate. This is significant for the development plan.

There are several applications of this solution.


First one is the improving efficiency of training sessions. During training sessions both trainers and trainees spend a lot of time that’s why efficiency is very important for sustainability. With the SNA it is easier to assess supply and demand of trainers and trainees, their preferences, expertise and experience. With the centrality measures we can improve the efficiency further. For instance people with higher centrality and betweenness have more potential to be demanded as trainers and be better trainers. People with high betweenness can create connections between people and suggest another people considering their needs.

Second one is the development plan for employees.

Development plan has two aspects, training people and connecting them to the rest of the company. This is a long-term plan. In the beginning people are going to chose which trainings they can choose or there may be a mandatory program that they should attend. This is a very nice way to create connectivity among entry-level people. Because they will have trainers they will also have connections with more experienced people in the beginning. As the time goes on these people will have opportunities to be trainer too. This solution can be expanded to isolated employees. Because we now have the network map of everybody, we can suggest isolated people a training session that they are interested in. This will both create a network and teach them new things. Furthermore we can have isolated and experienced people. If we can make an isolated member trainer o certain subject, he will automatically create connections with people.

One important question that needs to be answered is why train employees that much that eventually will leave the company. When we first enter the company our agreements are 2-year agreements. When a junior person employed legally they are not allowed to leave the job within 2 years. That’s way it is very important to get as much from employees and give as much to them.

In conclusion this solution is not one time solution. The information gathering and planning should be continuous process. For instance these surveys could be taken quarterly to see the updated network of people with the experience they have gained and plan that to do next. This will keep people connected, up to date.

Social network analysis and innovation research

Social network analysis as a creative methodology of research and exploration was invented in 1960s and 1970s by social psychologists. It has been furtherly developed with multiple disciplines such as mathematics, statistics and computing. As a result, the collaboration led to a rapid development of the SNA. Currently, it has been used in many researches and disciplines. 
The concept of generating innovation by using SNA is simply make use of the fundamental principle of the SNA, which is embedded level/units researchers want to innovate into the SNA system and finally measure from different levels such as the node-level, the local-level, and the network-level to judge if the possible innovation could be realized. 
Data required 
The use of SNA in innovation research does not have specific requirement for the data because innovation is a thing that never been proved or conceptually existed. Whatever researchers want to innovate, they just need to collect, filter and organize the data. For different research areas, data requirements are different. Anything could be in the dataset including persons/individuals, teams, organizations, concepts, patents, etc. Data will be imported to the SNA system and analyze, finally SNA will export those measures. Researchers use those measures to determine if the innovation is possible to realize and achieve. Or if those measures proves that the innovation is valuable to realize. We can say the the acquisition of data for innovation research is easy. 
Network measures 
There are four most important measures for the use of SNA in innovation research which are network density, centrality, betweenness, and centralization. There are also four types of performance measures which are robustness, efficiency, effectiveness, and diversity. Those concepts grouped with several measures with various corresponding advantages and disadvantages regarding the use. 
Network density
This rate is expressed in a form of number from 0 to 1. Density is used to explain the number of ties in a network and the connectedness in the network. If the density is close to 1, the network is defined as dense. Oppositely, if the rate is close to 0, it is a sparse network. 
Centrality
Centrality includes two levels which are local and global. It is expressed as a rate from 0 to 1. Local centrality considers ties that directly connected to the node, however, global centrality centrality considers indirect ties that are not directly connected to that node. 
Local centrality measures are about how many nodes are connected to a particular node; Global centrality measures on the distance among different nodes. 
Betweenness
It is a further developed concept and measurement of centrality. Betweenness explains the extent that a particular node lies between other nodes in a network. A node in a network with few ties may play an critical role and be central to the network. 
Centralization
It explains the extent to which a whole network has a centralized structure. Centralization describes a fact that the extent to which the connectedness come from the density is organized around particular focal nodes. It is an very important complementary measures. 
Robustness
It is measured by studying how it become fragmented as an increasing fraction of nodes is changed or removed. 
Efficiency
Efficiency is a term that is used to determine if nodes can access other nodes instantly. It aims to reduce time and energy spent on contacts.
Effectiveness
Effectiveness is used to make those cluster of nodes reached through non-redundant contacts.  However, each cluster of nodes are independent. 
Diversity
Nodes must be diverse in nature if the performance wants to be good. 

SNA is used to explore causal mechanisms related to innovation research. It could help researchers diagnose problems that cannot be realized under a routine methodology. Researchers will have some surprising findings that cannot be derived by routine research. Measurements will lead researchers to a new area that never has been explored. New interviewees will soon be identified and researched. As a result, it is probable that innovations will be generated. Then management will make use of the innovation and make changes on the organization.

Blog Assignment- COI

Social Network Analysis

Challenge
       Identification of suitable web software that can perceive instances of conflict of interests among the various authors and reviewers within the field of Computer Science.

Background on the use of SNA
       Conflicts of interests are situations that arise from biased decisions. Given the dynamic nature of man, COIs are caused by various numbers of reasons ranging from any defined human interaction or relationship. Detection of COI in the last decade has become emphasized because of the need to have accurate and equal processes like contract acquisitions. In the field of research, detection of COI is imperative in situations where ethical and legal implications have big potentials to damage the writers or target audience. The challenge presented in the research on COI is depicted in ‘connecting the dot’ literature or applications that are existent in a number of study cases. COI is difficult to detect because of the insufficient amounts of information during research. However, in some cases, there are present explicit and implicit amounts of information on the internet that can be applied in the detection of COI.

Data Required
       The type of data required in the SNA comes from bibliographic literature specific to the field of Computer Science. Another type of data required is (friend of a friend) FOAF documents acquired from sources where relationships are explicit. Important to highlight in the information gathering process is the validation of the source through an observation on the levels of integration. For instance, in a database, sites containing different works of the same author should have high levels of integration between them. It is in this that the most preferred data comes from public social networks. Public sources offer the capacities to address the challenge of integration and representation of data as real-world problems. Moreover, public sources are readily available and accessible. Integration of the UCINET analytic software will allow predictive, qualitative, and quantitative evaluation of the FOAF and DBLP documents. This will be done through the measure of collaboration (closeness) between authors in the same literature field.

Important Network Measures
       Given that the collected information comes from persons that have somewhat fixed relationships in the field of academia, the following measures are significant in the SNA.

Social Distance
       This measure refers to the level of divergence between persons in different societal groups. The measure is not physical but assesses divergence under the notions of race, class, gender, ethnicity, and economics. Through use of UCINET, the application will highlight the degrees of divergence between authors from different subgroups.

Disambiguation Algorithm
       The measure checks on whether a certain FOAF or DBLP database has multiple references that refer to the same entity.

Name Reconciliation Algorithm
       The measure analyzes context connected with a certain individual to identify similarities and differences. The measure is employed after the identification of multiple references from the same entity.

Co-Author Relationship
       The COI measure assesses the weight of relationships between authors to identify collaboration of assumptions and biases in their writings. This is the degree of closeness or togetherness applied in predictive analysis.

Applications of SNA to the Challenge
       The SNA is important in the study because it first diagnoses the problem. Through the identification and measure of co-author relationships, SNA identifies the depth of the problem in terms of the level of bias and assumptions made. If similarities are more, the SNA suggests COI is low, but if differences are more, the SNA reveals COI is high. SNA is equally important because the levels of COI act as evaluators of scientific research. In this, low levels will suggest conformity, meaning the pieces of literature are accurate. In meaning, scientific topics that have high COI instances are less applicable given the levels of bias and assumptions. The literature contexts are inaccurate.

Blog Assignment:

Problem: I have a problem about how to use SNA to identify the qualification of workers who are suitable for cross training in an organization.

Situation: This is one problem that I faced when I study the Hayward business case: Baria Planning Solutions, Inc.: Fixing the Sales Process.
                Baria Planning Solution, Inc, a consulting company, has business on different sector, like, energy sector, government sector, manufacturing sector, and retail sector. One of the problems of this company is the utilization of its sales support team has inexplicable shortage. The yearly utilization across sales support functions looks fine; however, it has utilization problems in some specific months due to different accounting period of different sectors. For example, the government’s accounting period is ending at Jun 30, retail’ accounting period is ending at January 31, and manufacturing’s accounting period is ending at the end of calendar year. Therefore, we will know some sector of this consulting company face working overload in January. The best solution of this problem is cross training. For example, training one worker from the unbusy-government sector into the busy-retail sector.
The upper solution is offered by my professor, Protano, however, I still have one question: how can I identify the qualification of workers who are suitable for the cross training program. SNA offers me a good way to solve this problem.

I want to use SNA to answer the following questions
Q1: Who are the person has frequent connections between different sectors?
Q2: Who has other sectors’ working experience beside their current job? Who has different background with their current job?
Q3: Who are willing to working in a cross sector team with higher compensation?

To gather data to finish this analysis will not be difficult at all, because the consulting company has its own professional survey department.

By gathering the result of the survey above, I will be able to see who has the highest in degree, out degree in the company; I can see who has well connections between different subgroups; I can see who has the highest betweeness; I also well know who has different experience with its current job.

Action 1, take out the people who answer “yes” in Q 3. 
Result: we know who want to work in a cross sector team.

Action 2, put the people, who has different working experience with their current job, into an emergency group. 
Result: Therefore, when it is really busy, those people can work as a cross sector fireman.

Action 3, group the people who has high degree, high connections between different sectors into a volunteer group. At the same time, the company will offer cross training volunteer program.
Result: the volunteers can also working cross different sectors when the utilization is overloaded.


After leaning the SNA, I realized the SNA is a really helpful tool to solve my question about how to identify who is suitable for cross-training program in an organization. 

Social Network Analysis

One of the fundamental problems facing the modern world is terrorism. This is a global threat that requires a significant new approach to address. One of the ways this can be examined is through social network analysis (SNA). This is the mapping and measurement of the relationships and flows that exist between people, groups and organizations (Perliger and Pedahzur, 2011). The people and groups are the nodes in the network while the relationships and flows are the links in the networks. To solve a problem using social network analysis, there is need to collect data. This might be difficult or easy to acquire depending on its nature. There is also a need to implement network measures that help evaluate the success of the analysis. Specifically, social network analysis helps in diagnosing problems that can help in the development of solutions. This can be applied to a variety of issues. As this paper demonstrates, social network analysis can be used in addressing the issue of terrorism.
Using SNA to Address Terrorism
The importance of using social network analysis when dealing with terrorism came to the fore after the 9/11 terrorist attacks in the United States (Ressler, 2006). Terrorist organizations mostly use networks to carry out their activities. This is opposed to the conventional enemy states that use hierarchical and formal methods of engagement. Instead, the terrorist groups now have networked organizational structures (Ressler, 2006). This allows them to have the ability to plan and launch attacks more quickly. Social network analysis can be an important tool that can help in fighting terrorism. They help the authorities in mapping out the terrorist networks with a view to dismantling them (Perliger and Pedahzur, 2011).
Data Needed and the Ability to Get It
The most important data in the social network analysis is to combat terror in information records (Ressler, 2006). The technological advancements mean that terrorists are also advancing on communication technology. Since they are spread out thinly in small groupings rather than the formal armies that have barracks and other identified installations, telephony communication is important (Perliger and Pedahzur, 2011). There has also been a rise in the use of social media among the terrorists. Groups such as the Al-Shabaab, Boko Haram, and ISIS have frequently used social media sites such as Facebook, Twitter and YouTube to spread their messages (Perliger and Pedahzur, 2011). If the authorities can get data from the communications companies, they would be a step ahead in creating the analyzes that can help dealing with the problem of terrorism.
However, there are some difficulties in getting this data. While the government can devise ways of tapping into communication, it would be easier if the companies just voluntarily gave the information. Opponents sharing this information raise the issue of ethics as a reason companies should not breach the privacy of their customers (Ressler, 2006). The opponents argue that governments should respect the privacy of citizens to communicate freely since it is within their rights. However, a counter-argument can be made that the practice of analysis happens daily in commercial life. Online retailers use the information they get from customers to analyze their trends with an aim of predicting their future behavior. This means that while the privacy concerns are genuine, the pros brought about by winning the war against terrorism far outweigh the cons (Ressler, 2006).
Most Important Network Measures
When dealing with the graphical representation of human relationships, it is important to have some measures that enhance the level of insight. In the social network analysis for fighting terrorism, the most important measures are the centrality measures. In this regard, the degree centrality measure and the between centrality measure are most important (Perliger&Pedahzur, 2011). The degree centrality measure is useful in identifying the nodes that have the most links to other nodes in the network. The nodes that have high degree centrality are often influential or have strategic important in communication for the network (Perliger and Pedahzur, 2011). The betweenness centrality measure shows the nodes that frequently act as connectors to other nodes in the network. These nodes are often the crucial gatekeepers of information within the network (Perliger and Pedahzur, 2011).
How the SNA Helps
The social network analysis helps in the diagnosis of the challenges that exist. With regards to fighting terrorism, it can help in a variety of ways. A proper analysis can identify some of the major characteristics that increase the likelihood of terrorist organizations being lethal(Ressler, 2006). For instance, there are some ideologies that increase this likelihood. If an organization that is highly religious or it combines its religious ideology with ethnic or nationalist ideology, then it is more likely to engage in lethal activities. On the other hand, organizations that hold environmental, human rights or anarchist convictions are less likely to engage in lethal activities. Young and fledgling organizations are also less likely lethal as compared to large, well-established and networked organizations(Ressler, 2006).
The analysis can also help in mapping terrorist networks. This can be explained by an example of two known terror suspects. If the authorities monitor these two individuals, the process might be too slow for it to achieve the results that would enable the saving of lives. This is where social network analysis comes in. The authorities would need the communication information of the two men. If these records are analyzed, it is possible to get contacts that the two individuals have in common. The next step would be an analysis of the contact information of the shared contacts to establish another level of common contacts. This analysis by now would have established a triad that represents the network. This process is repeated till the network expands to reveal an adequate picture of a terror network (Perliger and Pedahzur, 2011).
Once the network has been mapped, the next step is the mathematical analysis. This helps to identify the important insights such as the most central figure, the most connected individual, or who is the most crucial link in the network. This information can then be used by the authorities to target the individuals. For instance, a terror plot can be dismantled if the most important leaders are eliminated. This shows that the network analysis can be effective in giving the authorities a clear picture of a terror network that is not hierarchical.

In conclusion, social network analysis is an important technique in helping map out the relationships between people, groups, and organizations. If used properly, it can help address some of the challenges that face the society. For this to happen, however, the relevant data must be availed. The accuracy of the data influences the accuracy of the analysis. The analysis can then be used in diagnosing the problem; thus, enabling the relevant parties to bring about change. Therefore, this paper has shown that with proper analysis and the availability of adequate and accurate data, terrorist organizations can be mapped; thus, allowing the authorities to take the relevant action.
