SCHRIER, FOUNDING EDITOR, 1962-1987Published Quarterly by the Schrier Research LaboratoryPsychology Department, Brown UniversityProvidence, Rhode IslandISSN 0023-6861POLICY STATEMENTThe Laboratory Primate Newsletter provides a central source of information about nonhuman primates and related matters to scientists who use these animals in their research and those whose work supports such research. The Newsletter (1) provides information on care and breeding of nonhuman primates for laboratory research, (2) disseminates general information and news about the world of primate research (such as announcements of meetings, research projects, sources of information, nomenclature changes), (3) helps meet the special research needs of individual investigators by publishing requests for research material or for information related to specific research problems, and (4) serves the cause of conservation of nonhuman primates by publishing information on that topic. As a rule, research articles or summaries accepted for the Newsletter have some practical implications or provide general information likely to be of interest to investigators in a variety of areas of primate research. However, special consideration will be given to articles containing data on primates not conveniently publishable elsewhere. General descriptions of current research projects on primates will also be welcome.The Newsletter appears quarterly and is intended primarily for persons doing research with nonhuman primates. Back issues may be purchased for $10.00 each. We are no longer printing paper issues, except those we will send to subscribers who have paid in advance. We will not accept future subscriptions, unless subscribers are willing to pay $100/year. (Please make checks payable to the Brown University Psychology Department.) Readers with access to electronic mail may receive a notice when a new issue is put on the Website by sending the message subscribe LPN-WARN your-own-name to listserv@.(Send the message subscribe LPN-PDF to receive PDF files by e-mail; or the message subscribe LPN-L to receive the nongraphic contents of each issue.) Current and back issues of the Newsletter are available on the World Wide Web at </primate>. Persons who have absolutely no access to the Web, or to the electronic mailing, may ask to have paper copies sent to them.The publication lag is typically no longer than the three months between issues and can be as short as a few weeks. The deadline for inclusion of a note or article in any given issue of the Newsletter has in practice been somewhat flexible, but is technically the tenth of December, March, June, or September, depending on which issue is scheduled to appear next. Reprints will not be supplied under any circumstances, but authors may reproduce their own articles in any quantity.PREPARATION OF ARTICLES FOR THE NEWSLETTER. – Articles, notes, and announcements may be submitted by mail, e-mail, or computer disk, but a printed copy of manuscripts of any length or complexity should also be sent by regular mail.. Articles in the References section should be referred to in the text by author(s) and date of publication, e.g., Smith (1960) or (Smith & Jones, 1962). Names of journals should be spelled out completely in the References section. Latin names of primates should be indicated at least once in each note and article.

Goodwin, Susan A. James, Kelly E. Lane, Michael C. McDermott, Rebecca L. Rodgerson, and Nancy A. Ator Johns Hopkins University School of Medicine, Department of Psychiatry and Behavioral Sciences, Division of BehavioralBiologyIn our laboratory, we had often discussed our desire to create an area in which our singly housed, adult male ba-boons could be released to exercise. The opportunity to do so arose when an environmental enrichment grant from the Center for Alternatives to Animal Testing at Johns Hopkins University provided funding for such a project. Thus, the goals of the present study were to cre-ate an area large enough for baboons to safely engage in species-specific behavior (i.e., free movement, explora-tory behavior, foraging) and to learn whether exposure to this environment would be correlated with changes in target behaviors considered indicators of psychological well-being.MethodsSubjects: Six adult male baboons (Papio anubis; Primate Imports, New York, NY, or Southwest Foundation for Biomedical Research, San Antonio, TX) served as sub-jects in the present study. The six baboons (BB, DC, SY, CY, DE and SC) had been in the laboratory for at least three years and had been subjects in behavioral pharma-cology studies. During the present study, the behavioral pharmacology studies in which they participated included acute exposure to psychoactive compounds. Subjects were individually housed in stainless steel primate cages equipped with a bench running along one cage wall. The home cages, which provided 10 square feet of floor space (46.5 cubic feet total space), also served as the experi-mental chambers, so the behavioral pharmacology ex-periments took place in the home cage. Such experiments typically involve the use of one or more levers, stimulus lights, tones, and food pellet delivery. The baboons had visual and auditory access to other baboons.The baboons had continuous access to tap water from a spout at the front of their cages and received a daily ration of Lab Diet (®PMI Nutrition International) or Pri-mate diet (®Harlan Teklad) biscuits, one or two pieces of Amy K.

The authors would also like to thank Dan Rodgerson for the technical expertise he lent to the project, and Robert J. Adams, DVM, for helpful comments during the protocol review process and manuscript preparation.fresh fruits or vegetables daily, and children’s chewable multivitamins. Daily feeding occurred in late morning (never prior to time spent in the enrichment room). The enrichment program already established in the colony, which included human interaction, access to three or more toys (forage boxes, puzzle feeders, mirrors, Kong® toys, wood logs), and music continued without change during the present study.The overhead lights in the housing room were on for 13 h/day (6:00-19:00 h) and off for the remaining 11 h/day. Natural light also illuminated the room.Routine physical examinations (under ketamine hy-drochloride anesthesia) occurred every two weeks or ap-proximately once per month, depending on the study in which each subject was serving.All protocols were approved by the Johns Hopkins University Animal Care and Use Committee. Animal care and use and facility maintenance followed the Guide for the Care and Use of Laboratory Animals (1996) and the U. S. Animal Welfare Regulations. Johns Hopkins University is accredited by the Association for Assess-ment and Accreditation of Laboratory Animal Care Inter-national.Room Construction: It was vital that the time and effort required to create the enrichment room space be manage-able and that the expense stay below the $6000 received for the project from the Animal Welfare Enhancement Award. Ultimately, by using resources already available to us, we were able to manage the time and effort required without affecting the normal daily functioning in the labo-ratory.The space designated for the enrichment room had been constructed as an animal housing room (i.e., wall and floor surfaces met Guide standards; air was vented externally), and all environmental aspects (e.g., tempera-ture and humidity) were controllable by laboratory per-sonnel. The space was not needed for housing animals when the project began. The room has 145.8 square feet of floor space (663.5 cubic feet of total space), a fully functional sink, and a steel railing on three walls.A door had to be constructed such that baboons would be able to be safely transferred in and out of the room using the shuttle system described below. In order to accomplish this without permanently altering the room, a door measuring 83.25” by 47.25” was made of aluminumsheets in a frame of 3” x 1.25” 6061 architectural alumi-num, and installed in the existing door frame in front of the existing door (see Figure 1). A sub-frame containing a portion of the front wall of an old baboon cage was mounted in the center of the new aluminum door and welded to the larger door frame such that the shuttle cage could be connected to the embedded guillotine-style door. Once the shuttle is attached, the guillotine-style doors on the shuttle cage and the new “cage front” door are opened and the baboon is able to pass from the shuttle into the room. The cage front door is shut behind the baboon. When a baboon is not in the room, the aluminum door functions as any door would, allowing personnel into theroom so that it may be cleaned between baboons.Figure 1: The door constructed to safely transfer baboons in and out of the enrichment room.A painted wooden structure was also manufactured to block baboon access to the sink and its pipes (see Figure 2).The structure is hinged at the front, allowing easy ac-cess to the sink by personnel; fasteners prevent the baboon from opening the lid to the sink. Electrical outlets were covered with metal plates that were screwed in over them. Experimental Design and Procedures: The psychologi-cal well-being of nonhuman primates must be based on individual needs, thus a single-subject design was used in which each subject served as his own experimental control (Sidman, 1960). A subject’s target behavior was meas-ured before the intervention (i.e., exposure to enrichment room) and then measurements in the home cage continued as baboons were periodically exposed to the enrichment room. Prior to any enrichment room exposure, the fre-quency of the target behavior in the home cage was re-corded using a time-sampling procedure (Martin & Pear, 1992) in which 2-minute observations were conducted every hour for 8 hours (i.e., every hour from 7 a.m. to 3 p.m.) at least three days a week, over at least three weeks (i.e., a minimum of 72 two-minute observations). After subjects began spending time in the enrichment room, the home cage observations occurred once per week on a day when the baboon was not scheduled to be in the enrich-ment room (e.g., eight 2-minute observations on Fridays). Figure 2: A baboon in the enrichment room. The wooden structure on the left is the painted and hinged structure used to block baboon access to a sink located in the enrichment room. Shown in the picture are various types of plastic zoo balls, plas-tic tires, tree branches, mirrors, plastic chains, and cardboard for shredding. In addition, small food items (e.g., raisins, peanuts, cashews, popcorn, sunflower seeds, etc.) are placed throughoutthe room to encourage foraging behavior.The frequency of behaviors was recorded by the ob-server marking a behavioral checklist that included the following behaviors: pacing, rocking, bouncing, circling, self-biting, self-grooming, sleeping, huddled posture, masturbating, aggressive behaviors, playing with toy, lip-smacking, grunting, eating, and drinking. Similar behav-iors have been defined previously in our lab as a part of assessments to examine acute and chronic drug effects (Ator et al., 2000; Goodwin et al., 2005; Goodwin et al., 2006).Three baboons (BB, DC, and SY) were identified as exhibiting behaviors in their home cages for which a de-crease in the frequency may indicate improvement in psy-chological well-being. For baboon BB, the behaviors were pacing and circling in his home cage. For baboons DC and SY, a “huddled” posture, operationally defined assitting with chin on chest and being unresponsive to nor-mal stimuli (e.g., our saying his name or offering food treats), was identified as such a behavior. In addition, baboon SY was identified as engaging in excessive grooming. For all three baboons, manipulating items/toys provided in the home cage was identified as a behavior for which increases in frequency may signal improve-ments in psychological well-being and was also recorded.Periodic cage washes (e.g., every two weeks) require baboons to be transferred out of their home cages and into a temporary cage via a “shuttle”. After the shuttle is at-tached to the front of a baboon’s home cage, the guillo-tine style doors on the cage front and shuttle front are lifted and the baboon is able to enter the shuttle. The doors are then shut, and the baboon is transferred to a temporary cage while his home cage is washed. The same procedures are used to transfer the baboons back to their home cages. Although most baboons readily par-ticipate in this procedure, some baboons consistently re-quire coaxing to enter the shuttle. Typically, veterinary technicians attempt to coax baboons into the shuttle by placing fruit in it, and when this fails, the back wall of the home cage is cranked forward so baboons have no choice but to enter the shuttle. In these extreme situations, ba-boons may experience some level of stress associated with the cage wall being cranked forward.Three baboons (CY, DE, and SC) from the colony were identified as consistently required coaxing and/or cranking of the back wall in their home cage in order to transfer them in the shuttle for routine cage washes. De-creasing the time taken for these baboons to enter the shuttle was presumed to lower the stress levels experi-enced by these baboons when they require such transfer.Exposure to the enrichment room began after pre-intervention data had been collected. Between 7 a.m. and 12 p.m. (i.e., prior to daily feedings), individual baboons were transported from their home cages to the enrichment room in the shuttle 2-3 times per week. Two dependent variables were used to measure the effectiveness of expo-sure to the enrichment room:1.Target Behaviors: For baboons BB, DC, and SY, the frequency of the behavior(s) identified for each baboon as described above (i.e., circling/pacing, huddled posture, excessive grooming, and handling toys) were systemati-cally recorded by a trained observer before any subject entered the room (i.e., in the weeks prior to entering the enrichment room the first time) using checklists described above.2.Shuttle Behavior: For baboons CY, DE and SC, the latency to enter the shuttle for transportation was re-corded in multiple instances before any exposure to the enrichment room; recording continued after exposure to the enrichment began. The maximum latency to enter the shuttle voluntarily was defined as five minutes, after which time the back wall was cranked forward to leave the baboon with no choice but to enter the shuttle.Each baboon spent 30 minutes in the enrichment room where he had access to numerous objects and toys manu-factured or otherwise suggested for nonhuman primates, including tires, various types of plastic balls, trees, mir-rors, wood pieces, knotted ropes, plastic chains, etc. (see Figure 2; Bio-Serv, Frenchtown, NJ; Desert Plastics, Al-buquerque, NM; Otto Environmental, Milwaukee, WI; Primate Products Inc., Woodside, CA; and Steiner Enter-prises, Lafayette, IN). The same objects were kept in the room, but were cleaned and arranged differently between baboon visits. In addition, small food items (e.g., raisins, peanuts, cashews, popcorn, sunflower seeds) were placed throughout the room for each baboon to encourage forag-ing behavior. The objects manipulated and duration spent in the enrichment room were recorded for each baboon.After 30 minutes, the shuttle was pushed up against the guillotine door to the room and the doors on the shut-tle and the cage door were raised for transportation to the home cage. Baboons typically returned readily to the shuttle. If a baboon did not do so, a technician placed a piece of fruit in the shuttle to coax the baboon into it. As noted above, daily feeding (i.e., primate biscuits and fresh produce) was restricted to post-enrichment room partici-pation, to increase the likelihood that baboons resisting entering the shuttle might be coaxed with the fruit.Data Analysis: Data are presented for individual ba-boons. As subjects were also participants in on-going behavioral pharmacology studies, only data collected on days when no drugs were administered were included in this data analysis. As described above, a time-sampling procedure was used to assess the frequency of a specific behavior in the home cage for any given day Martin & Pear,1992).Thus, the total number of episodes across the eight 2-min.observations (one each hour for eight con-secutive hours)that occurred in one 24-hr period was av-eraged across days for the periods before and after en-richment room exposure. In addition, the 2-min. observa-tions were combined within each day by adding the fre-quency of occurrences of any given behavior and then dividing the total frequency by the number of total min-utes spent observing in order to express a rate. In this way, the rate for each day served as an independent ob-servation for comparing frequencies before and during exposure to the enrichment room using Student’s t-test (one-tailed).For the individual latencies to enter the transport shuttle, logarithmic transformation of individual latencies were analyzed using Student’s t-test (one-tailed). Changes in the mean frequency of a specific behavior, or the mean latency to enter the shuttle, were deemed statis-tically significant at the 0.05 level or better for individual baboons after exposure to the enrichment room.The data are also presented in graph form as (1) the mean (±SD) frequency of each measure for each baboon prior to any exposure in the enrichment room (PRE) and (2) the frequency of that measure following each expo-sure to the room. In this way, patterns of change over time as a result of repeated exposure to the enrichment room may be detected.ResultsFor baboon BB, repetitive pacing/circling in the home cage was identified as the target behavior prior to the start of this study. Using the time-sampling procedure de-scribed above, the mean (±SD) frequency of pac-ing/circling episodes in the home cage prior to any visits to the enrichment room was 2.19 (±1.39) (see Figure 3). After exposure to the enrichment room, the mean (±SD) number of pacing/circling episodes significantly de-creased to 0.643 (±0.63) (t=3.948; p=0.0002).Figure 3: The mean frequency of pacing/circling episodes per two-minute interval in the home cage of baboon BB. Data here, and in Figures 4, 5, and 6, are the mean (±SD) frequency ob-tained using a time-sampling procedure before exposure to the enrichment room (PRE), and the frequency observed following exposure to the enrichment room.For baboons DC and SY, a “huddled” posture was identified as a target behavior for which a decrease fol-lowing exposure to the enrichment room may indicate an improvement in psychological well-being (see Figure 4). As noted previously, the “huddled” posture is defined as sitting with chin on chest and being unresponsive to nor-mal stimuli. For baboon DC, the mean (±SD) frequency of the “huddled” posture prior to exposure to the enrich-ment room was 5.25 (±1.29). The mean frequency after exposure decreased to 4.21 (±1.31), a statistically signifi-cant decrease (t=2.02; p=0.03; see Figure 4). For baboon SY, the frequency of “huddled” posture observed in the home cage also decreased after exposure to the enrich-ment room. Prior to the first exposure to the enrichment room, the mean (±SD) frequency of a “huddled” posture for SY was 1.88 (±1.37). This was significantly de-creased to 0.71 (±0.83) (t=2.92; p=0.003).Figure 4: The mean frequency of “huddled” posture per two-minute interval in the home cages of baboons DC and SY.Excessive grooming was also identified as a target behavior for baboon SY for which a decrease in the fre-quency may signal an improvement in his psychological well-being (see Figure 5). The mean (±SD) frequency of grooming episodes prior to exposure to the enrichment room was 3.77 (±1.45). The mean (±SD) frequency of grooming episodes after exposure decreased to 2.36 (±0.74), a statistically significant decrease (t=3.34;p=0.0008).Figure 5: The mean frequency of grooming episodes per two-minute interval in the home cage of baboon SY.Figure 6: The mean frequency of episodes of “playing with toys” per two-minute interval in the home cage of baboon BB.Behaviors for which an increase in frequency might signal improved psychological well-being were also char-acterized. For baboon BB, there was a significant in-crease in the frequency of “playing with toys” in his home cage after exposure to the enrichment room (t=4.48; p<0.0001). As shown in Figure 6, the frequency since exposure to the enrichment room generally increased. Prior to enrichment room exposure, the mean (±SD) fre-quency of baboon BB “playing with toys” in the home cage was 2.27 (±1.91). After the first exposure, the mean (±SD) frequency was 4.9 (±1.54).Figure 7: The mean (±SD) latency (min.) to enter the shuttle from the home cages of baboons DE and CY before (PRE) ex-posure to the enrichment room and after exposure. The maxi-mum latency was five min., after which the back wall of the home cage was cranked forward.Some of SY’s and DC’s behaviors in the home cage that may signal improvement in psychological well-being when increased (i.e., playing with toys, lip smacking, and grunting) were not significantly changed (data not shown) after exposure to the enrichment room.The latency to enter the shuttle for transportation from the home cage to the enrichment room was studied in three baboons (DE, CY, SC) known to require coaxing, and often cranking the back wall of the home cage, to get them into the shuttle. As shown in Figure 7, baboon DE required a mean (±SD) latency of 3.45 (±1.82) minutes to enter the shuttle prior to any exposure in the enrichment room. After the first exposure, the mean latency to enter the shuttle significantly decreased (t=7.4; p<0.0001). For baboon CY, the mean (±SD) latency to enter the shuttle prior to exposure was 0.53 ± 0.57 minutes, a significant decrease after exposure (t=2.1; p=0.023).Despite coaxing with fruit, one baboon (SC) failed to return to the shuttle after entering the enrichment room. Fortunately, the baboon was one who readily pressed his thigh up against the bars for ketamine injections in the home cage and also did so in the enrichment room. While ketamine is routinely used in lab settings for its sedative effects, it is a drug with potential for abuse, and studies have illustrated that nonhuman primates will self-administer ketamine (Lukas et al., 1984; Moreton et al., 1977). Thus, since intramuscular ketamine clearly served as a reinforcer for this baboon, the veterinary technician was able to sedate the animal with ketamine in order to remove him from the room. When this also needed to be done at the end of his second visit to the room, this ba-boon was dropped from the study.DiscussionThe objective of the present study was to improve the quality of life for baboons in our lab through exposure to an expanded environmental enrichment program. We could not simply assume, however, that exposure to the enrichment room would result in an improvement in the psychological well-being of our subjects. Thus, we iden-tified three baboons with maladaptive behaviors in their home cages and compared the frequency of these behav-iors prior to enrichment room exposure to the frequency of the same behaviors after exposure, and found signifi-cant decreases in their frequency.In addition, we found that two baboons would more readily enter the transport shuttle after exposure to the enrichment room. That is, the stress resulting from crank-ing the back wall forward and “forcing” baboons out of the cage and into the shuttle for transport no longer oc-curs for these baboons, since they now readily enter the shuttle. This is important because baboons must be trans-ported out of their home cages for regular cage washes.Thus, our data support the idea that exposure to the enrichment room improved the psychological well-being of the baboons. In addition, while only one of the ba-boons showed an increase in the use of toys in his home cage, it is possible the baboons experienced significant increases in their psychological well-being that were un-detected by our outcome measures. Moreover, by docu-menting the smaller objects manipulated (e.g., Kong® toys, balls made of different materials, plastic chains, mirrors) while the baboons were in the enrichment room, we also were able to identify individual toy preferences for individual baboons. This has resulted in more effec-tive enrichment being provided in the home cages.Another goal was simply to increase the amount of activity in which the baboons were able to engage. Tech-nicians consistently noted in the records that baboons spend a majority of time in the enrichment room moving around and “exploring.”A discussion of promoting the psychological well-being of nonhuman primates in laboratories would not be complete without mentioning possible causes of abnormal cage behaviors. While it is not possible to know why one baboon engages in maladaptive behaviors when others do not, one theory with an abundance of evidence asserts that removing an infant from his mother’s care too soon can result in the formation of abnormal cage behaviors later in life (Altmann, 2001; Bellanca & Crockett, 2002). Neither information about the age at which a baboon was removed from his mother’s care, nor descriptions of early life experiences, are routinely provided with nonhuman primates upon arrival at research facilities. For example, while the actual age of baboon BB is not known, he was a wild-caught baboon who weighed a mere 8.2 kg and was lacking his canine teeth upon arrival, leaving no doubt he arrived as a juvenile. Moreover, when he arrived at quar-antine (and for a period of time after arriving in our facil-ity), BB was housed with a second male baboon that was bigger and dominated BB. Thus, the cage behaviors ex-hibited by BB later in life may have been shaped as a consequence of being taken from his mother too soon and/or being caged with a dominant older male early in life. While many factors certainly influence the formation of maladaptive behaviors, housing and rearing conditions, early life experience, and colony procedures clearly play a role. Indeed, a retrospective analysis in a colony of rhesus macaques concluded that factors influencing the development of stereotypic and self-injurious behaviors in rhesus macaques included intrinsic factors (i.e., males exhibit more maladaptive behaviors than did females), rearing conditions, housing conditions, colony manage-ment practices, and research protocols (Lutz et al., 2003). Regardless of the cause of abnormal cage behaviors, it is important to examine how environmental enrichment may be useful for decreasing these behaviors.Since we ended our data collection, the enrichment room has been available for all baboons in our colony, and we have encountered baboons that do not readily return to the shuttle for transportation back to their home cages. Specifically, we have had three instances, other than the one reported above, when baboons would not readily exit the enrichment room. In these instances, the technicians tried to coax the baboon into the shuttle by placing fruit in it, but found it required considerable time before the baboons would exit. That is, after a period of 1-4 hours baboons eventually returned to the shuttle, and those baboons are not currently visiting the enrichment room. Other methods for encouraging return to the shut-tle, however, are being tried. For example, we have found that turning off the room light was successful with one baboon. Based on our experience during and after the present study, 30-45 minutes seems to be the ideal amount of time in the room after which the majority of baboons will readily exit the room without incident.It is our hope that other laboratories will use an en-richment room for caged nonhuman primates and will find it a valuable tool for increasing their psychological well-being. Facilities that house very large numbers of nonhuman primates may find it difficult to expend the time, space, and money to offer such enrichment to all animals. While it would be wonderful to give all the animals in a lab access to an enrichment room, it would not be as expensive to at least provide it to those animals who need it most. Indeed, our data support the notion that the psychological well-being of nonhuman primates exhibiting maladaptive behaviors can improve by expo-sure to an enrichment room.It should be noted, however, that some unique vari-ables may have contributed to our success. The veteri-nary technicians in the Division of Behavioral Biology are responsible for the daily care of the same animals, and the baboons serve as subjects in behavioral experiments for a number of years (i.e., studies are not terminal). Thus, the baboons are extremely familiar with their vet-erinary technicians. In addition, the baboons have a his-tory of shuttling for cage washes and so the act of moving from their home cages to the enrichment room was famil-iar to them. Nonetheless, exposing baboons with target behaviors indicative of poor psychological well-being to the enrichment room resulted in an apparent improvement in psychological well-being. The ease of replication of the enrichment room in other nonhuman primate colonies is contingent on the availability of space, time, and some financial support.In conclusion, participation in the expanded enrich-ment program enhanced the standard enrichment provided in the home cages, and also appeared to improve the psy-chological well-being of individual baboons with identi-fied maladaptive behaviors in our research program.

This competition was under the guidance ofthe Secretary of State to the Ministry for Higher Education and Scientific Research.”Since technical activities hold great importance to theSB , the executive committee planned to establish student chapters in order to improve technical activities and in-crease the number of society members. In this way, the SB executive committee has encouraged students to re-new their IEEE memberships by adding technical society memberships and requesting volunteers to establish new student chapters including the IEEE Systems, Man, and Cybernetics Society (SMCS), IEEE Aerospace and Electron-ic Systems Society, IEEE Com-putational Intelligence Soci-ety, IEEE Education Society, IEEE Computer Society, IEEE Engineering in Medicine and B iology Society, IEEE Robot-ics and Automation Society,SB members gather in March 2009 during a technical workshop with Dr. William A.

Alimi, SB counselor, Tunisia section treasurer, and the school director; Dr. Mourad Loulou, Tunisiasection chair; and Dr. Fathi Ghorbel from Rice University in Houston, Texas.Students are provided numerous opportunities to join the SB or renew their IEEE membership during many organized SB stands that are set up throughout the year.6 IEEE POTENTIALSand the IEEE Signal Processing Society. In June 2009, theSB chair established the first student chapter with the SMCS, which was the first one in Region 8. During January and Feb-ruary 2010, the other student chapters were established.Fun, games, and feedbackDuring 2010, the SB planned social events includ-ing a day trip to Chambi Mountain in Tunisia, a visit to SOS C hildren’s Village inMahres, and a one-day tripto Zaghouane Mountain.More home-based eventsthat were used to rally SBmembers were a videogame contest, a dinner, anda buffet to celebrate theend of the academic year.The SB also organized freeeducational activities forthe benefit of students atENIS. These included Latex,a s ecurity contest, and IEEEXplore training.“Since women’s activitiesare also beneficial in order tointensify the female presencein electrical and electronicsengineering areas, the SBexecutive committee has encouraged female volunteers toestablish a Student Affinity Group in the school,” Hammounadds. “This group was organized by Fatma Elleuch and ap-proved in February 2010. As of June 2010, 37% of members are women and 80% of them are members of IEEE Women in Engineering.”One of the successful keys of getting the ball rolling so quickly was that the SB has a good relationship with school leaders, the section executive committee, the local chapter chairs, and other scientific association leaders,” Kammoun says. A good number of high-quality free activities—tech-nical, educational, and social—that are organized for IEEEMembers in the school have helped the SB to attract new members and keep members involved. The most notable achievements for the SB were the inauguration in ENIS and the SB s membership devel-opment, he adds.“The SB goals are updated annually taking into account the students’ feedback and the degree of success of the orga-nized activities during the past years,” Kammoun explains. “The SB goals in the near future are to help students in other schools to establish new SB s in Tunisia, organiz-ing more educational activities such as the Technical English Program and attracting good sponsors for SB events.”—Craig Causer is the managing editor of IEEE Potentials .The opening of the SB office in January 2010 continued the rapid growth trend for the ENIS branch.IEEE Potentials is interested in hear-dent branch grown in popularity?

Most students get through these classes daydreaming. The only motivationthat brings them back to these classes is amark against their names, which would oth-erwise hold them back from taking theirexams. The irony is that the lecturers arewell aware of the rationale of theiraudience and find pride in coercingrelate the true meaning of educationbetter when made to delve in a subject.The reach between “what it does” to“how it does” mutates a listener to alearner. No wonder more and more stu-dents are scouting for research-oriented projects as well as mentors. The variousapex institutions of academics as well as industries appraise research as one of theirkey criteria for selecting applicants ratherthan their ability to grasp topics when lec-tured for continuous hours. It is this timewhen those letters of recommendation from sor type, from my perspective, best suits the need.It has been my experience that full-time lecturers,especially if they have industry or consulting expe-rience, bring a broader perdents or course material presented. In general,they know the theory behind the material,but, more importantly for the future engi-time lecturer will more often have time tospend with his/her associated studentclasses, more time to spend on the generalpopulation. This will go a long way in helpingthe engineers-to-be grasp the material being pre-sented in class—they can ask more specific ques-tions on the material from someone who hastime to respond and has their interests at heart.In my opportunities to associate with research-oriented professors, I found them mostoften being assigned to graduate students, orgraduate assistants, having little, or nothing, to dowith the undergraduate population.

But this is not where the plug needs to be pulled. A practical know-how of everything being put across in the theoretical world with all the exceptions and modifications is very important for a better under-standing of a concept. Research leads to in-depth study and realization. One starts at the surface and keeps digging until its core. This is better than being made to start at the core where you can relate noth-ing and finally when you real-ize the surface applications,you are not in a position torecollect your way out fromthe core.Professors who are more intoresearch are better equipped tohandle a novice mind of thestudent and mold it a properway. They are aware of thecommon doubts, setbacks, andmyths a student faces as com-p a r e d t o t h e i r c l a s s r o o m-oriented counterparts. Mentors encouraging research are known to share a better rap-port with their pupils. Hence, they are subjected to doubts and problems with lesser hesitation. These pro-fessors encouraging research are able to better reach the minds of students by encouraging deeper move-ment into the subject until a clear picture is obtained. It is when students are made to study something with their mind exploring all possible directions that they are able to get a better hold of the subject. On the other hand, when being subjected to long lectures, the equation between a teacher and student is like that between a computer and a programmer. The program does only what it has been programmed to do without reaching for new possibilities and venturing into newer directions.Most of the research being undertaken is done with a commercial end product/service in mind. The economic and commercial viability of any research and its end prod-uct is always taken into consideration all through its course. Students are exposed to opportunities and experi-ence closer to the industrial world. This is the sole reason as to why engineering students are made to undergo industrial training, working on some project as a part of their curriculum.Although both genres may be indispensable for a qual-ity education, nevertheless the debate between the prom-inences of two may have defendants on the other side also. I however, have always been a staunch believer of the talisman: “I listen, I forget. I write, I remember. I do, I understand.”—Nakul Jain (nakul17@) is the vice-chairperson of IEEE-ASET (Amity School of Engineer-ing and Technology) New Delhi, India. He is pursuing an engineering degree in electronics and communications.simply an observation of their drive to advance the base of knowledge in their particular field of study, that drive being more important than education of the students.That also brings to mind my experiences while recruiting engineers from Georgia Tech, Rensselaer Polytechnic Insti-tute, Carnegie-Mellon, and Perdue, all well known for their research activities. While the graduates of those institutes were well trained as e ngineers, I had difficulty in recruiting engineers for m anufacturing support, field e ngineering, field support, and similar nonresearch engineering jobs. The stu-dents were more interested indevelopment (and research) posi-tions and lacked the interest inother aspects of a career. I was ableto bring some into the company,and they were highly successfulwith an engineering career outsideof the development arena.From my perspective, we needboth types of professors in oureducational programs today. Thefull-time lecturer has the greatestimpact on the engineering profes-sion in that he/she provides thebase knowledge for the practicing engineer-to-be. Themajority of new engineers will not continue their educa-tion into graduate-level programs. Most often, the newengineer is more interested in getting a job and startinghis/her new career. The task of the full-time lecturer is toensure the students have the needed knowledge and skillset to be successful in industry. At the same time, theresearch- o riented lecturer is important in the continuingadvancement of knowledge, especially in technology.When I began my career, circuit boards had lines and linespacing measured in ten mil line widths. With continuedresearch and development, line width and spacing todayare measured in nanometers. Such continued advances donot just happen by accident. It requires the desire anddrive of the research-oriented lecturer (as well as the workof dedicated scientists who may have had the opportunityto associate with those lecturers).A final thought on the subject: While I have not done anybasic research on the topic, I suspect that most of the newtexts are written by research-oriented lecturers, as new tech-nology is discovered, brought to maturity, and proven to bea workable solution to some of today’s problems. As thenew texts are written, they become the new material to beincorporated into the curriculum of the courses taught by thefull-time lecturer. Thus, the knowledge base continues toexpand and change, allowing the full-time lecturer to bringnew material to the attention to the students in their classes.I believe that the full-time lecturer and research-oriented lecturer are both important to the success of oureducational system. While one provides the day-to-dayeducation of the new engineer, the other probes to under-stand and determine future direction of technology. As towhich is more important—I say again, “It depends,” but Ilean more to the full-time lecturer’s overall impact to thestudent and their preparation for their future career.Nakul Jain Raymond E.

Shannon passed away in 2001, at the age of 84, but information theory is 60 years young. Shannon himself demonstrated discrete sources of information through the example of natural language, and today a similar analysis is being applied in the realm of yet another language, the language of life. One of the unique features of information theory is its sim-plicity, not withstanding the mathemati-cal rigor that Shannon has used in his seminal 1948 paper. The definitions for information content and information entropy are both elegantly conceived, though counterintuitive, in certain ways. As per information theory, a random selection of English alphabets and space would be more informative than aphrase that is picked out at random from a newspaper or a blog (hence the choice of the title for this article). When we reconcile with this apparent coun-ter-intuitiveness, we are on the learning curve of information theory.In this article, we take a fresh look at the two seminal concepts of infor-mation theory—information content and information entropy. We also dem-onstrate how these could be used to analyze DNA sequences, through toy example.Information contentShannon defined a measure for infor-mation contained in a message, based on the probability of each symbol 5a 1, a 2,c a n 6 in it. Suppose we have n symbols emanating independent of each other from a source, with probabilities 5p 1, p 2,c p n 6 respectively, then the information content of any message ofDigital Object Identifier 10.1109/MPOT.2010.938146© INGRAM PUBLISHINGsize k made out of these symbols is given byI52ani51log p i.This equation is easily explained with an example of English language. It is well known that the different letters of the English language appear with differ-ent frequencies in text. A popular esti-mate is given in Table 1. We can conceive these estimates as probability of occur-rences of the concerned alphabets (by dividing by 100) and these figures can be used to calculate the information con-tent of “kpb wcy xz” and “i love you,” which are shown in Tables 2 and 3 respectively.In the case of “i love you,” the infor-mation content is computed as shown in Table 3 (we ignore spaces). “kpb wcy xz” has a higher information con-tent (53.859) than “i love you” (36.38). Thus, in information theoretic perspec-tive, “kpb wcy xz” is more informative than “i love you.” Is this not a counter-intuitive conclusion? How could one say “kpb wcy xz” is more informative than “i love you?” To the layman, the first phrase is mere rubbish than infor-mative, and the second one makes per-fect sense.Perhaps one needs to discard the l ayman’s interpretation of the term “information” (a message received and understood or knowledge acquired through study, experience, or instruc-tion) and associate information in S hannon’s sense with “surprise.” The information content in a message would then be linked to the amount of surprise it creates in us; in other words, an unusual scenario has more information than a usual scenario. Would a newspa-per run a headline like, “President of the United States Alive”? The counterintu-itiveness now starts to vanish. The reader is warned about the danger of carrying these examples too far.From the sense of real-world knowl-edge, these examples can be debated in very different ways. One could also reexamine the examples by taking the probability of an adjacent pair of letters (or even trigram of letters) and see that “i love you” is much more “informative” that what we have computed initially. It may also be noted that other measures of information content are possible. A simple equation I5g1/p would be an example. Here, information will be inversely proportional to probability, which captures Shannon’s idea.Calling all bellsA more real life example could be that of a calling bell. Consider a house where a calling bell is installed for the visitors to announce their presence at the door. The on/off state of the calling bell indicates the presence or absence of visitors. Now imagine various kinds of houses—from one where people try to gate-crash and one where nobody ever visits. We quan-tify the cases by the on/off probabilities of the calling bell, P on and P off. Let us consider seven cases, as in Table 4.Table 4 is amenable to intuitive expla-nation. A calling bell that is always ring-ing and also a calling bell that neverNOVEMBER/DECEMBER 20101718IEEE POTENTIALSrings, both have no useful functions. Both of them naturally have zero infor-mation content and can never deliver any surprises. We find that in houses where there is a surprising visitor after a long time or in a busy house where there is a rare silence, the calling bell delivers maximum information.Information entropyShannon’s next great idea is that of information entropy. The general notion of entropy, as in thermodynamics, is worth steering clear of, espe-cially if it is also new to the reader. After decades, the idea of entropy in thermodynamics seems to be still cloudy. We could attempt to look at infor-mation entropy H (after Hartly, by one popular account) as the average information per symbol in a message.Consider a message of length n , with symbol set 5a 1c a n 6 and probabili-ties 5p 1, p 2,c p k 6 respec-tively, where n is assumed to be large. The symbol a i , which has a probabil-ity of p i to occur, is expected to occur n 3 p i times in the whole mes-sage. Then the total infor-mation I T , of the message is given byI T 52a 1n 3 p i 2 log p i .The average information per symbol is the informa-tion entropy H , given byH 5I T /n 51/n 2a 1n 3p i 2 log p i5a p i log p i .The significance of information entropy is that it tells us the minimum number of bits required to encode the message digitally. This would mean that if wemeasure the entropy of a message, we can know if there is scope for com-pression of the message. For example, a DNA sequence consists of four let-ters, A, G, C, and T. A simple coding mechanism is to code each letter with two bits (as there are four signals, log 24 = 2). However, if it is known that probability of symbols of A, G, C, and T are 0.15, 0.35, 0.15, and 0.35, respec-tively then H 52a p i log p i 5210.15#log 10.15211220.35#log 10.35210.15#log 10.15210.35#log 10.352251.88 b.This would mean that this DNA sequence can be c ompressed ((2 – 1.88) / 2) = 5.9%. Such measures are extremely useful in building huge biosequence databases. They give us clear directions on what is achievable in terms of compression. For instance, many experiments to com-press DNA sequences have resulted in actually expanding it. Once the theoreti-cal limits are understood, futile efforts can be avoided.With English text, the entropy is (based on Table 1):2a p i log p i 5 p (‘a’) 3 log p (‘a’) 1 p (‘b’) 3 log p (‘b’) 1 % 1 p (‘z’) 3 log p (‘z’) 1 p (‘ ’) 3 log p (‘ ’)5 2.7 bThe number of bits required to represent English text, if we consider that all letters and space have same probability is log 2(27) = 4.75 b. This shows that Eng-lish text can be ideally compressed to 42.55%.All the previous examples are based on a model of probability of one letter at a time. If we take probabilities of two letters at a time, entropy reduces to 4.07 b; three letters reduces it to 3.36 b, and four letters further reduces entropy to 2.77 b. Such an approach of considering “n -mer” probabilities is possible with DNA sequences also.Finally, we would like to give a pic-ture to applying information measures in analyzing biosequences.
