Ph.D. Program Description

The Doctor of Philosophy (Ph.D.) degree in Human Sciences (with a specialization in Communication Disorders and an emphasis in Audiology, Speech and Hearing Science or Speech-Language Pathology) is designed to prepare scholars both in applied and basic aspects of communication. The focus is to prepare scholars for leadership roles in teaching, research, and/or clinical management, depending on a student's program goals and objectives.
 

Knowledge Base

The concept of a Ph.D. is reflected in the policy statement from the Association of Graduate Schools (1979). The degree of Ph.D. "is conferred in recognition of a candidate's high level of scholarly competence and demonstrated capability to conduct and report significant research independently and effectively. Ph.D. programs involve scholarly and research activity directed mainly toward the acquisition of new and fundamental knowledge. Ph.D. programs are to be distinguished from practitioner-oriented doctorates which prepare for the application or transmission of existing knowledge and that may be intended to serve as preparation for professional practice. . ." The requirements and knowledge base for the Ph.D. in Communication Disorders is consistent with traditional practice although it has a strong applied and professional component. In summary, the focus of this degree is the traditional teacher-scholar model. However, doctoral education in Communication Disorders is not a single focused entity but varies to accommodate diverse students' objectives in career goals and specializations.

The traditional student entering the program, holds a Bachelor's degree with a liberal arts and science focus in addition to background in the area of human communication science and disorders. The student may also have a Master's degree in communication science and disorders in either speech-language pathology or audiology or related discipline (e.g., linguistics, Psychology, Engineering). However, a Masters degree is not a condition of admission.

The program is designed to be individualized and flexible enough to allow individuals to prepare to be researchers, academics, and/or administrators. The course work required consists of courses in human communication science and disorders along with cognate areas, e.g., learning, psychoacoustics, physical acoustics, sensory physiology, along with laboratory and clinical investigation. There is a common knowledge base in communication science and disorders, i.e., speech-language pathology or audiology as a prerequisite or part of any doctoral program.

The program requires that students become familiar with the scientific and professional literature in communication sciences and disorders undergirding the areas of concentrated study. The common goal of the program is the development of a thorough understanding of the scientific process and of the knowledge and research skills needed to apply that process to the generation of new knowledge and new applications of knowledge. This statement is not to minimize or restrict the extent or type of research training or to imply that such training will be the same for all students; rather it is based on a recognition of the applicability of scientific training to both basic and applied knowledge. "The doctoral program should develop the interests and capabilities for the generalization of new knowledge, regardless of the nature of their (student’s) primary career goals" (Moll, 1983).
There are five general principles concerning the integration and sequencing of content, which depend on the goals and specialization of individual students.
• Doctoral programs will usually be concerned with in-depth mastery of subject matter in a rather narrow area. However, achieving this goal generally requires a broadening of the knowledge base in other fields related to the student's special area of interest, e.g., psychology, health science, physiology, education, business administration, and physical and social sciences.
• Second is the development of knowledge and skills that represent the necessary and basic tools for carrying out clinical, research, or teaching functions-for example, computer science, laboratory instrumentation, statistics, behavioral research methods, tests and measurements, as well as an understanding of the history and philosophy of science.
• The third content area involves clinical or intern experience. These might include ongoing involvement in clinic work, supervision, teaching, or research.
• The fourth area involves the research experience. The development of research skills requires sequential experience in posing questions and hypotheses, designing research projects to evaluate them, and carrying out the research. Such experience will extend throughout the doctoral program. The dissertation project is intended to be the capstone to the research experience, not the beginning of it.
• The final area is related to teaching. One of the goals of doctoral education is to prepare the individual as an academic professional who is equipped to teach students. This will require content dealing with principles of education, methods of evaluation, instructional technologies, and teaching approaches.

Supervisory Committee - (Minimum of four graduate faculty)

The chair of the committee must have Graduate Faculty status and be from the program-granting the degree. The committee must include a minimum of two Graduate Faculty from Communication Disorders (one can be the Supervisory Committee Chair). There must be at least one Graduate Faculty Member external to the academic department and area in which the degree will be granted.

Annually all students will be evaluated with regard to progress in the program. The committee chair will meet with the student on an annual basis and provide a written summary to the other Committee members. A copy of the summary will be provided to the Department Governance Committee.

The student is allowed to change mentors (advisors) through negotiations with the current advisor and future advisor. Any such changes must be approved by both the chair of the Department Graduate Committee and the Chair of the Department. Changing mentors is to be seen as a process whereby the needs of the student are better met by the skills of a different mentor.

Program Faculty

The graduate faculty in the Division of Communication Disorders sets policy for its Doctoral Program.  Differences in policy interpretation between a supervisory committee and the Division Governance Committee will be brought to the Division Graduate Faculty for resolution.

Curricular Requirements

Area of Emphasis

Students entering the Ph.D. program may or may not have completed professional studies at the undergraduate and masters degree levels.  Students entering the Ph.D. program without this background and wishing to acquire certification and licensure in either Audiology and Hearing Science or Speech-Language Pathology will be expected to acquire this knowledge concurrent with their doctoral studies.

Audiology - Hearing Science

The Ph.D. program prepares researcher/teachers and scientists for advanced study of the auditory and balance mechanisms.  Emphasis is on biophysics, neurophysiology, and advanced investigatory techniques. Research aspects of the program prepare students to work independently on the design and implementation of scientific investigations. Teaching experiences assist in students' development of skills necessary for university teaching positions in communication science and disorders. Students wishing to function primarily as clinical practitioners will matriculate into the Au.D (Doctor of Audiology) program. The Au.D. program prepares students for clinical positions in hospitals and other medical settings as well as for free standing private practice. 

Speech and Language Pathology

The Ph.D. program in Speech and Language Pathology is designed to prepare students for research and teaching. Students pursue advanced studies of theoretical and applied issues relevant to the acquisition, remediation, supplementation, and/or loss of human communication abilities. Research aspects of the program prepare students to work independently on the design and implementation of scientific investigations. Teaching experiences assist in students' development of skills necessary for university teaching positions in communication science and disorders.

Program Goals and Objectives

Each student program will contain at least four goals or objectives. It is the responsibility of the student and the chair of his/her Supervisory Committee to ensure that at least one goal will address each of the following areas: 
1. Content Emphasis Area(s)
2. Research Design and Analysis
3. Associated Content Area(s)
4. Career Objectives
It is the responsibility of the supervisory committee to assist students to develop a program of study that will adequately prepare them to meet the multiple program goals and objectives that are required in the program document.

It is expected that students will produce a minimum of two manuscript-quality documents related to their research experiences.
Teaching/Research Presentation and Service Experiences
Doctoral students are expected to complete experiences that will include lectures, workshops, inservices, and/or research presentations to students, colleagues, faculty members, and professionals in practice. In addition, students will engage in professional consultations related to issues within the areas of their expertise. The breadth and frequency of these experiences will be outlined in the program of studies document and will be individualized to the needs and skills of students. Some portion of these experiences must involve culturally diverse and exceptional populations. Students will receive feedback regarding service experiences from mentors or their designates.
Computer, Network, and Instrumentation Proficiency
All doctoral students in the Communication Disorders Program are expected to have a working knowledge of electronics and laboratory instrumentation common to their field of study. It is expected that all doctoral students will demonstrate computer proficiency in the following application areas: word processing, statistics, spread sheets, and graphing. Deficiencies in all computer and instrumentation areas will be assessed upon entrance to the program and removed early in the program through coursework, directed readings and/or laboratory experiences. Proficiency must be demonstrated to the mentor or mentor's designate by the time the student applies to write comprehensive examinations.
Multi-cultural Requirement
This requirement is designed to ensure that students are exposed to diverse cultural perspectives related to the areas of emphasis in their doctoral programs. This requirement can be met through new coursework and/or clinical experience. The amount of coursework and type(s) of clinical experiences will be determined by the Supervisory Committee. An attempt will be made to integrate this requirement with student's stated professional goals. Examples for meeting this requirement are listed below.
1. Combination of previous experiences and/or additional coursework or practica Additional coursework may be selected from those listed in (2) below.

Doctoral Seminar
The Doctoral Seminar provides graduate faculty with an opportunity to mentor doctoral students by working intensively with them on outcome-based projects of shared scholarly interest. All doctoral students are required to compile a minimum of four consecutive semesters of Doctoral Seminar (prior to candidacy) under the supervision of the chair (or co-chair) of their Doctor Supervisory Committee. The Doctoral Seminar plan for each student will be described in the Program of Studies and approved by the supervisory committee. The Doctoral Seminar plan will include a description of projects, meeting schedules, expected products, and evaluation procedures. Doctoral Seminars are not to be construed as formal classes but rather as individual mentoring experiences with faculty advisors. The sequence and content of Doctoral Seminars is as follows:
Doctoral Seminar One:
Introduction to doctoral study including review of (1) doctoral program planning; (2) career planning; (3) writing, spreadsheet, teaching, library search, and statistical analysis software tools; and (4) dissertation planning. In addition, students are required to be actively involved in ongoing research as outlined in their doctoral program plan. Finally, students are to attend the Brown Bag Research Seminars offered by the Communication Disorders Division.
Doctoral Seminars Two - Four:
Students are required to be actively involved in ongoing research as outlined in their doctoral program plan. All students are to attend and participate in the Brown Bag Research Seminars offered by the Communication Disorders Division. 
Admissions Criteria and Procedures
Evaluation criteria for admission (cumulative point system)
a. GPA (Undergraduate)
b. GPA (Graduate)
c. GRE (must have all 3 components of test)
d. Recommendations--Three received from people able to comment on student's potential to perform in a Ph.D. program.
e. Copy of Masters thesis or other research papers (if available)
f. A written statement of the rationale for pursuing doctoral education and intended professional goals upon completion of the degree.
g. Previous experiences
h. Minority status
i. Potential for scholarly activities
Sponsoring mentor
The student must be sponsored for admission by a faculty mentor (If the sponsor is not a member of the graduate faculty, arrangements must be made for co-sponsoring /mentoring). A faculty member agreeing to serve as a sponsoring mentor should provide a written statement of that intent during the admissions review process. This statement will be included in the application file. 
Comprehensive Examinations
Form of the Comprehensive Examination
The comprehensive examination is intended to allow the student to demonstrate mastery of subject matter within an area of study. The examination may not be waived, but may be tailored to the special needs of the individual student. It should not consist only of writing answers to isolated questions hour upon hour. Rather, in addition to demonstrating proficiency in limited content areas, the student may also be expected to integrate information across an extended project or paper. The final form, content, and duration of the examination will be left to negotiation between student and advisor.
Evaluation of the Comprehensive Examination
Student responses will be read and evaluated by the supervisory committee and others who may be enlisted by the committee. 
Evaluation Choices
Each part must be passed in order to pass the comprehensive exam. The written comprehensive examination can be passed without an oral examination. If the written examination is not completed successfully, the committee has a choice of two options. The first option would be to have an oral examination that would be limited to the specific portion of the written examination not successfully completed. The second option would be to require the student to rewrite the failed portion(s) of the examination. Failure to pass the second attempt at the comprehensive examination will result in automatic review of the student's performance with the possibility of termination from the program. 
Dissertation
Role of the Dissertation and Dissertation Research
The doctoral dissertation should: (1) reveal the student's ability to analyze, interpret and synthesize information; (2) demonstrate the student's knowledge of the literature relating to the project or at least acknowledge prior scholarship on which the dissertation is built; (3) describe the methods and procedures used; (4) present results in a sequential and logical manner; and (5) display the student's ability to discuss fully and coherently the meaning of the results. The work must be described in sufficient detail to permit an independent investigator to replicate the results.
The dissertation is the beginning of one's scholarly work, not its culmination. Dissertation research should provide students with hands-on, directed experience in the primary research methods of the discipline, and should prepare students for the type of research/scholarship that will be expected of them after they receive the Ph.D. degree. (From: The Role and Nature of the Doctoral Dissertation: A Policy Statement – Council Of Graduate Schools)
Dissertation options: 
1. Traditional dissertation focusing on one research project. 
2. Multi-project dissertation consisting of a series of related research projects, prepared as individual research reports with an integrated review of the literature, integrated discussion, and an integrated future research directions section. 
A student selecting the multi-project dissertation approach should work closely with the Supervisory Committee throughout the course of the research to ensure agreement among committee members about focus, procedures, and analysis. However, final approval of the multi-project plan will occur only after the student has been admitted to candidacy. 
On occasion it becomes necessary to reconstitute the Supervisory Committee to satisfy particular demands of the dissertation. This is done in consultation with the Supervisory Committee Chair and must be approved by both the Departmental Graduate Committee Chair and the Department Chair.
Dissertation Defense
The final examination for the doctoral degree (dissertation defense) is oral and open to members of both the University community and the public. During the dissertation presentation and general questioning all persons may be present. However, at the end of the public hearing there will be a closed questioning portion of the examination where all persons except the Candidate, doctoral supervisory committee, and invited faculty must be excused.
Policy for Doctoral Student Funding
Full Doctoral Student Assistantship
A full-graduate assistant assignment with full tuition remission will receive an annual stipend to be paid monthly.  Such appointments must be continuous for four (4) full months within the semester dates and must be at a stipend no less than the minimum level as determined annually in the Guidelines for Graduate Assistantship Eligibility for Student Benefits.  Included in the Guidelines is the provision for a payback of tuition by the student in the even the student doesn’t hold the assistantship for three (3) months.
The requirements for a full doctoral student assistantship include:
1. At least nine (9) hours of academic credit per semester  (both fall and spring) six (6) hours of academic credit during the summer or permission of the major advisor and Department Chair.
2. A work requirement of 20 hours per week involving teaching, supervision, and/or research that will be consistent with the students’ program goals.
3. Because the students are considered full-time students with work responsibilities, they are not to hold other employment as they have a full-time responsibility at UNL.
4. Students should consider doctoral study a full-time job and thus should spend a majority of their time on campus when they are on assistantships.
Part-Time Doctoral Student Assistantship
The stipend for a part-time, but continuous, doctoral student will be negotiated with their advisor and the Chair of the Department of Special Education and Communication Disorders.  In general, individuals who are less than full time will not receive tuition remission.  The stipend will be based on the workload of the student.
Non-Continuous Doctoral Student Assistantship
The tuition remission and stipend for a non-continuous doctoral student will be negotiated with the student’s advisor and the Chair of the Department of Special Education and Communication Disorders and consistent with University guidelines for graduate assistantships.
Philosophy on Work Activities for Doctoral Students Who Receive Full-Time Financial Aid From Departmental or University Funds
Doctoral students who are awarded financial aid during their doctoral education will be assigned activities that are consistent with their development as scholars. The purpose of doctoral education is to prepare students for academic and research positions.  Within that context, the goals for assistantships should be constructed with the following goals in mind: 1) lead to the learning and improvement in teaching and research skills, 2) learn how to manage laboratories and laboratory equipment, 3) learn and use current computer technology appropriate for communication sciences and disorders, and 4) be involved in activities that lead to the improvement of technical writing skills. Independence in all of these goals is expected toward the end of a doctoral student’s program of studies.
Each advisor is responsible for insuring that doctoral students working under their direction have the opportunity to acquire the necessary skills to survive as scholars within the discipline.  Faculty members in Communication Disorders have generated a list of appropriate work activities.  Students and faculty are advised to consult the list of activities when formulating work activities each semester.  It should be understood that variations in the time allocated for each activity will vary for each assignment and across academic advisors.  Students may negotiate changes in workloads and activities with advisors.  However, at no time should students be expected to perform the following or similar activities unrelated to their doctoral education: 1) clerical work for a faculty member such as filing or office/lab organization/cleaning that is unrelated to a research project to which the student is involved, 2) attend a class and receive work credit for that activity, 3) run errands unrelated to teaching or research responsibilities, 4) take care of the faculty member’s house or family member, and 5) count commuting time as work time.
Any disagreements or complaints about how students are allocating their time for their assistantships should be worked out with the major faculty advisor.  When issues cannot be resolved, it is recommended that there be a meeting with the Graduate Committee Chair, Chair of the Department, faculty member and student in order to resolve any problems.
General Student Responsibility
Nothing in this Handbook is intended to supplant information contained in the University of Nebraska-Lincoln Graduate Bulletin. It is the responsibility of the student to be familiar with the information presented in the Bulletin and to know and observe all regulations and procedures relating to the program he/she is pursuing. In no case will the Graduate College waive regulations or grant exceptions because a student pleads ignorance of or contends that he/she was not informed of the regulations or procedures of the UNL Graduate College. Graduate Bulletins may be obtained at the University Bookstore or the Bulletin may be reviewed on-line at the UNL Graduate College web site.
