Language Exam 2
What are some guiding principles for intervention in the L4L stage?
1. curriculum-based instruction such as discovering what is required to participate in class and what content will be addressed; 2. integrating oral and written language such as providing opportunities in both contexts and providing a variety of language experiences for addressing each objective; 3. go "meta" by directing conscious attention to language and cognition and stating rules and principles; 4. participate in RTI (Lecture 2.6, Guiding Principles slide)
What is a T-unit?
A T-unit is one main clause with all the subordinate clauses and nonclausal phrases attached to or embedded in it; all coordinated clauses are separated into separate T-units, unless they contain a co-referential subject deletion in the second clause ("He goes and loses it"). Clauses that begin with coordinating conjunctions and, but, or or would be considered to make up a new T-unit. Using T-unit segmentation provides a more realistic picture of syntactic units in the L4L phase than does the method we would use for children in the developing language period (Paul, p. 431-2); a minimal terminable unit; one main clause and all subordinate clauses attached to it (Lecture 2.6); Example: "My brother is going to the store with his girlfriend" = 1 T-Unit (https://quizlet.com/10769033/additional-language-analyses-flash-cards/)
What are the DSM-5 diagnostic criteria for ASD?
A. impairment in social communication, B. repetitive behaviors and restricted interests, C. symptoms must be present in the early developmental period, D. symptoms cause clinically significant impairment in social, occupational, or other important areas of current functioning, and E. these disturbances are NOT better explained by intellectual disability (intellectual developmental disorder) or global development delay (see slides from October 3, Lecture 2.5)
Which unit is typically used for spoken language?
C-Unit analysis is usually applied to spoken language (https://quizlet.com/10769033/additional-language-analyses-flash-cards/).
So what is the only real difference between C-units and T-units?
C-units can also include incomplete sentences when used to answer questions. When counting T-units, incomplete sentences are excluded (Nippold, Later Language Development, p. 238)
What is a C-unit?
Communication units are defined as "an independent clause and its modifiers". A communication unit is an utterance that cannot be further divided without the disappearance of its essential meaning or a subordinate clause that is part of the independent predication. Main clauses can stand by themselves and can be segmented into one C-unit. Subordinate clauses DEPEND on the main clause to make sense. They cannot stand alone or be separated from the main clause. So a C-unit will either consist of a main clause or a main clause with its subordinating clause(s) (http://web.nmsu.edu/~valdez1/Communication%20Units_revised.doc); a communication unit; each independent clause and its modifiers (Lecture 2.6); Example: "My brother is going to the store with his girlfriend" (1 clause and 2 dependent prepositional phrases = 1 C-Unit) (https://quizlet.com/10769033/additional-language-analyses-flash-cards/)
True or False: It is NOT important that clinicians align intervention efforts with the general education curriculum.
False (KMA, p. 205)
True or False: Narrative intervention does NOT lend itself particularly well to a combination of skill-based and contextually-based intervention.
False (KMA, p. 209).
True or False: Children who present a great deal of pronoun confusion in their narratives should NOT be encouraged to specifically name the character every time it is referenced in the story.
False (KMA, p. 216)
What is verbal language acquisition like for children with ASD?
Structural language skills are extremely variable in ASD. The range of abilities across all age groups extends from nonverbal to verbose; a significant percentage of children with ASD develop at least some spoken language skills by the age of nine with only 9% remaining nonverbal in later childhood (Paul, p. 121).
True or False: Engaging in oral narrative tasks places greater linguistic, cognitive, and memory demands on the speaker than conversational exchanges, making this aspect of oral language functioning more challenging for children.
True (KMA, p. 203)
True or False: Addressing various goals in different activities that connect to a single story is one strategy for ensuring adequate attention to a learning target.
True (KMA, p. 209).
True or False: Research has shown that children with LI differ from their typically-developing peers in distinct ways when constructing personal narratives.
True (KMA, p. 214).
True or False: The use of literate language can influence how others perceive a narrative.
True (KMA, p. 217)
True or False: The context for discussing personal narratives should include actual experiences from the child's life.
True (p. 215)
True or False: Children's comprehension and production of narratives requires some specific language knowledge.
True (p. 216)
Which unit is typically used for written language?
Typically, T-Unit analysis is used with written language (https://quizlet.com/10769033/additional-language-analyses-flash-cards/).
How do you analyze a text's linguistic complexity?
You look at the MLU, number of utterances, and vocabulary (KMA, p. 206).
How do you analyze a text's structural complexity?
You look at the number of episodes, the development of the plot line and compare the simple versus the embedded plot structure (KMA, p. 206).
What is an important distinction to make when implementing intervention for narrative comprehension and production?
You need to decide whether the stories and narrative abilities will be the instructional focus of intervention or if they will provide the backdrop for other intervention targets (KMA, p. 209).
What is reading fluency?
accurate and effortless decoding at grade-appropriate reading rates using appropriate prosody and phrasing; one of the key goals of reading instruction identified by the National Reading Panel; requires rapid word identification which, in turn, enables reading comprehension; a crucial link between decoding and comprehension (Paul, p. 516)
What are narrative construction activities?
activities that allow children to apply the knowledge and skills they are learning in ways that are central to classroom success; children can be asked to retell a familiar story but are asked to independently or cooperatively modify the story by replacing key story grammar components with new information such as a new problem; they can also use cards that represent different story components and create a new story (KMA, p. 213)
What is an IEP?
an Individualized Educational Plan; it differs somewhat from an IFSP for infants and toddlers; requires participation and signature of all parties; includes a student's present level of performance, a statement of annual goals and objectives with criteria for determining achievement, a summary of all special educational and related services such as transportation to be provided, a statement of the extent of participation in the regular education program, justification of the student's placement in the least-restrictive setting for the pupil, a statement of modifications needed in the regular classroom program to accommodate the student, the projected dates for initiating services, the duration of services, and the proposed date of review (Paul, p. 481).
What is dynamic assessment?
an assessment strategy that enables examiners to assess children's language learning capabilities and their responsiveness to good language learning experiences within a very short period of time (Lecture 2.6, Dynamic Assessment slides)
What are some hybrid intervention strategies for syntax concerning complex sentences?
analyze forms taken from classroom content or high interest reading materials, talk about conjunctions, work on sentence combining (Lecture 2.6; Hybrid intervention slide)
What are some metalinguistic activities we can use to make the students more aware of language when writing?
ask students to rephrase a sentence or paragraph; rewrite a textbook passage; recast a text selection as a picture or cartoon; rework material from textbooks as diagrams or maps; editing written work; have them write a sample including errors so others can correct them; use word study approaches to spelling (Paul, p. 517)
What are some strategies for supporting the production of personal narratives?
assist children in learning the structural framework of personal narratives, encourage comments relevant to the topic, facilitate the use of specific and appropriate referents, and sequence events in temporal order in which they occur (KMA, p. 214-6)
Name some causal connectives.
because, so that (KMA, p. 216)
What is metacognition?
become more conscious and able to plan your thinking processes (Paul, p. 516); the ability to assess our own cognitive processes; we begin to build these skills at the L4L level; work on these strategies is an additional source of material for classroom collaborative lessons; it consists of comprehension monitoring and organizational and learning strategies (Paul, p. 517-8)
What is metalinguistics?
becoming more aware of a variety of other aspects of language (Paul, p. 516); being aware of how we talk and read; fluent reading and writing are the result of both practice of basic skills, such as decoding and graphomotor skills, as well as an awareness of the connection between "style" (tone of voice and prosody in reading; word and sentence choice in writing) and the intended meaning; used to support reading and writing fluency (Paul, p. 516)
What are some general assessment steps used when dealing with children who may have ASD?
before assessing, let the parents/caregivers know what to expect; during the assessment, involve parents in all parts of the evaluation; after the assessment, ask if behavior was typical (not sure if this is what she wants or if she wants what I put as next question; from Lecture 2.5)
What are the components of a comprehensive PBS intervention plan for behavioral issues?
behavior hypotheses to try to figure out what is causing the behavior; long-term supports to assist with the student's overall development and interactions for optimum quality; prevention strategies to change the environment and minimize the possibility of problems; functional communication training (FTC) in which adaptive and conventional communication skills are taught to replace maladaptive behavior; and consequential strategies which are outlines of how the team responds to both the replacement skills and the maladaptive behavior (Paul, p. 484)
What does multidisciplinary mean?
concerning assessment, it means that each professional carries out a relatively independent assessment, exploring the issues relevant to his/her discipline, then the team joins together to report findings (Paul, p. 238-did not read this chapter, but this is all I could find in the book)
What does transdisciplinary mean?
concerning planning, it means that specialists and teachers work together, not just within, but across their disciplines, to design an effective treatment program; services need to be coordinated among the specialists, in consultation with the regular or special ed teacher, to make sure the student's program is coherent and addresses all aspects of the student's needs and includes the family's perspective (Paul, p. 481)
What are some organizational and learning strategies?
creating inferential sets (figuring out what I already know about a topic), self-questioning (asking self-guiding questions), think alouds (clinician models thinking process), reciprocal teaching and buddy programs (grouping students so they can help each other complete a task), and the use of graphic organizers and sensory imaging (draw, map, or visualize material to help with comprehension and recall) (Paul, p. 518)
What does effective vocabulary intervention focus upon?
deep processing of word meaning, integration of contextual information, use of metacognitive strategies (Lecture 2.6, Semantic intervention slide)
What are some deficits in syntax/morphology that are common to those with ASD?
delayed acquisition (like other disorders); may rely on linguistic input; less complex language compared to peers with ID; difficulties with morphology; pronoun reversals (Lecture 2.5)
What are some deficits in semantics that are common to those with ASD?
difficulty establishing relationships between concepts and linguistic forms; limited knowledge of semantic relationships (e.g., agent-action like "daddy sit," action-object like "throw ball"); limitations in semantic knowledge lead to difficulty with: abstract words, double meanings, figurative language, and humor (Lecture 2.5)
What are some strategies for improving narrative COMPREHENSION?
discuss central concepts and background information, address vocabulary, digress from reading the text in strategic ways, engage in repeated readings, encourage the use of visual representations, discuss concepts following the reading of the text, use narrative dramatization and reenactments (KMA, p. 210-2).
What is pictography?
drawing and writing techniques to formulate representations of ideas, using simple sketches that move from left to right; also known as stick writing (p. 214)
What is literacy like for those with ASD?
early research considered some with ASD to be hyperlexic; today it is believed that there are much more varied reading patterns in larger cohorts of children; aspects of autistic cognition may also influence literacy development such as drawing inferences about characters' mental and emotional states, integrating information across text and with their own experiences and world knowledge, and using strategies for recovering uncertain meaning, all of which can pose significant challenges for those with ASD (Paul, p. 122)
What are some evidence-based methods for promoting reading fluency?
echo reading, choral reading, guided oral reading, partner reading, assisted reading, performance reading (Paul, p. 516-7)
What are some things done during effective language assessment for those with ASD?
evaluation of hearing, oral-motor skills, communication functions (verbally and nonverbally) and observation of abilities during a variety of activities; the CSBS:Communication and Symbolic Behavior Scales may be used to assess communication and symbolic development like gestures, facial expressions, and play behaviors; it uses 22 communication and symbolic rating scales (in 7 groups) with infants and toddlers whose functional communication age is between 6 and 24 months and for children up to 72 months (or 6 years old) who exhibit atypical development (Lecture 2.5)
What is intervention like for those with ASD?
first we LISTEN: to reports from parents, teachers, caregivers; to the child to initiate, respond, request, comment; and to the family's values and priorities; then we WATCH: to observe for "sticky" interests and communication attempts, successes, and breakdowns; the third thing we do is JOIN: by inserting self into play/topic theme; building rapport and trust; creating shared attention; and last, we STRUCTURE: by sharing focus of attention/incorporating personal interests; by increasing predictability, confidence, and flexibility; and by targeting goal areas in meaningful ways (Lecture 2.5)
What are the steps for identifying students for communication or language assessment in the L4L stage?
first you would start with screening which may be conducted at certain grade levels and may be a formal measure or locally-developed and informal and is better if the instrument is well-developed; then concerning referral and case finding, you can have a teacher referral or use checklists or specific criteria; next you would do standardized testing that should be administered in comprehensive batteries; you could give a comprehensive language battery, tests of pragmatics, and tests of learning-related language skills (Lecture 2.6)
What are some ways to support story retelling?
for children with poor knowledge of story structure, you can use a cloze procedure or small cards depicting key events from the story; small bookmarks depicting story structure symbols and tape-recorded retellings can also improve children's narrative productions (KMA, p. 213)
The characteristics of ASD are:
gaze aversion, ritualistic behavior, socialization difficulties, self-stimulatory behavior, hypo- and hyper-sensitivity to stimuli, restrictive interests, echolalia, emotional/behavioral deficits, poor play skills (Lecture 2.5)
What is echolalia?
imitating what others say (Paul, p. 268); may be immediate or delayed; may be pleasing or relaxing; may happen unintentionally, or may be used in functional ways; may be used to take a turn in a conversation, answer a question, or process information (Lecture 2.5)
How would you assess pragmatics in the L4L stage?
in conversation, you would pay attention to communicative intentions; contextual variation such as register variation, presupposition, and discourse management; and in narratives (Lecture 2.6)
What is skill-based instruction?
instruction that entails a clinician addressing some component of narrative abilities removed from the context of an authentic activity within the child's school day; this allows for the specific teaching of a skill, concept, or strategy in a systematic way (KMA, p. 209).
What is focused instruction?
instruction when a new concept or strategy is being introduced; students are given repeated practice within a carefully designed interaction and the clinician can slowly fade support (KMA, p. 209)
What is contextually-based intervention?
instruction which is embedded within a naturalistic environment and an authentic activity; the clinician provides support to the child during the active completion of a classroom task, responding to difficulties as they are encountered as teachable moments (KMA, p. 209).
What does interdisciplinary mean?
involving two or more academic, scientific, or artistic disciplines (https://www.merriam-webster.com/dictionary/interdisciplinary)
What does the self-discovery approach in the L4L stage do for students?
is motivating; results in deeper processing; enhances long term memory; uses a detective approach - crack the code, word sorts, searching for clues- to help them infer a word meaning based on a base word and an affix, etc.; use think alouds to help practice this approach (Lecture 2.6, Best Practices: Self-Discovery Approach)
What is scaffolding?
it involves identifying the student's zone of proximal development in curricular language skills and devising activities that support his current level of function (Paul, p. 487); using strategic questions and cues to support language learning within meaningful events (Lecture 2.6, What is Dynamic Assessment? slide)
What is a story or episode map?
it is a way to break down stories, both visually and verbally, into their key structural components; it graphically reflects the parts of the story and the relationship between the story's parts (KMA, p. 213)
What is LI?
language impairment (KMA, p. 203)
How do we choose goals for those with ASD?
look at the assessment results; from our observations: we can figure out their interests, what can be an incentive or motivate the child, and their skill generalization and consistency; determine functional use such as how their functional needs are being met and how they share their experiences and emotions; and take into consideration their family's priorities such as health, sleep, diet, daily obstacles, values, and culture (Lecture 2.5)
What is MLU?
mean length of utterance (KMA, p. 203)
What is language form like for those with ASD?
once some verbal language is acquired, articulation of speech sounds is relatively unimpaired across language phenotypes; concerning phonology, a significant proportion perform poorly on measures of nonsense word repetition which taps phonological short-term memory; other aspects of phon.processing appear to be more universally-challenging such as rhyme awareness and prosody and some may have distortions of speech sounds and voicing patterns; deficits in morphosyntax and grammar are more pronounced for those with ASD and for those with the ALI (autism language impaired) (Paul, p. 121).
What are the key components of a personal narrative?
orientation, complicating action, and resolution (KMA, p. 215)
What are the DSM-5 diagnostic criteria for Social (Pragmatic) Language Disorder?
persistent difficulties in the social use of verbal/nonverbal communication as manifested by all of the following: deficits in communication for social purposes, impairment in the ability to change communication to match context or the needs of the listener, difficulties following rules for conversation and storytelling, difficulties understanding what is NOT explicitly stated and nonliteral or ambiguous meaning of language; deficits result in functional limitations in effective communication, social participation, social relationships, academic achievement, or occupational performance; the onset of symptoms is the developmental period (Lecture 2.5)
What is language use like for those with ASD?
pragmatic deficits are universal and may be particularly evident in higher-level discourse processing and narrative tasks; tend to have significant deficits in conversational skill such as too many or too few initiations, poor topic maintenance, fewer contingent conversational responses, and non-contextual or socially-inappropriate utterances; producing higher proportions of contextually irrelevant propositions, poor referencing throughout the narrative and ignoring the motivations of characters or events; poor understanding of figurative and metaphorical language, poor inferencing skills and reduced ability to resolve ambiguous language (Paul, p. 121-2)
What are proto-declaratives?
preverbal attempts to get an adult to focus on an object or event by such acts as showing off or showing or pointing out objects, pictures, and so on, for the purpose of establishing social interaction or joint attention (Paul, p. 244)
When it comes to narrative abilities, children with LI....
produce shorter narratives with a smaller mean length of utterance (MLU), a greater proportion of grammatical errors, and have poorer cohesion between utterances; have difficulty responding to both literal and inferential questions about stories; produce narratives that are less well-organized and include less information; in fact, it appears that difficulties with connected discourse often persist even when other aspects of language functioning (semantics, syntax) move into an age-appropriate range (KMA, p. 203-4)
What are the principles of narrative intervention?
select appropriate and engaging texts, provide support in a variety of contexts, make targeted goals explicit, use varied teaching strategies, provide repeated opportunities to practice a skill or strategy, consider performance a success in relation to support provided, and shift responsibility for strategy implementation from the clinician to the student (KMA, p. 205-9).
What are the neurocognitive phenotypes of ASD?
sets of observed characteristics that are associated with a particular genetic profile concerning particular patterns of brain development and cognition; there are at least two distinct phenotypes of ASD: Autism Language Normal (ALN) and Autism Language Impaired (ALI) (Paul, p. 121)
Name some coordinated connectives.
so, but (KMA, p. 216)
What are some general tools used during assessment of ASD?
standardized, norm-referenced tests for language and social communication/pragmatics; profiles; questionnaires/parent interview; supplemental observation of play and behavior; ASD-specific assessment tools like the ADOS and ADI-R (Lecture 2.5)
What is a complex narrative structure?
stories with multiple sets of characters, embedded plot structure (KMA, p. 206)
What are some strategies for improving narrative PRODUCTION?
story retelling, story or episode maps, narrative construction, and pictography (KMA, p. 212-4).
What are some behavior issues in intervention?
students with LLDs frequently have attentional and behavioral problems that interfere with learning; we can use positive behavioral support to help alleviate these problems (Paul, p. 482).
What are some metalinguistic activities we can use to make the students more aware of language when reading?
talk about the language within the text; talk about how characters felt and have student read with that emotion; identify punctuation marks; answer questions such as "Which word appears more than once?"; use Readers' Theater to talk about the author's word choices (Paul, p. 517)
What are some models for speech/language services?
the RTI model, the Clinical model, the language-based classroom, consultation and collaboration (Paul, p. 520-2)
How is comprehension monitoring implemented?
the clinician will tell the student to do something in a voice that is too soft to be heard, spoken too fast to be understood, or spoken with competing noise (knocking the table with a wooden block); the students are told to ask if they do not understand the message; at the next level, adequate directions are interspersed with those that are inexplicit or ambiguous, contain unknown words, or are inordinately complex (Paul, p. 518)
What are some hybrid intervention strategies for semantics concerning vocabulary instruction?
the essential elements are to activate what students already know, provide description/explanation/example of new term, ask students to restate the description/explanation/example in own words, have students conduct visual symbolic representation of term, make connections among words and topics, have students discuss terms with one another, use both spoken and written contexts, refine and reformulate meanings, use the words for writing and additional reading, review words in coming weeks; you can use a metacognitive approach and/or build curriculum vocabulary through elaborated exposure; vocabulary skills are related to reading comprehension (Lecture 2.6, Hybrid intervention slides)
What is self-regulation?
the foundation for executive function; involves allocating cognitive resources, such as attention, planning, impulse control, and organizing when faced with a complex task; otherwise known as "thinking language," the little voice we hear in our own heads when we have to think through how to accomplish something difficult; curricula designed to address these skills may be quite effective in helping children succeed in school (Paul, p. 408); the ability to plan, organize, and execute actions efficiently using consciously-selected strategies (Paul, p. 450)
Name some forms of literate language.
the language of stories (Once upon a time, The end), the use of conjunctions, advanced syntactic structures such as elaborated noun phrases (preceding a noun with more than two modifiers, such as a big, fat, hairy cat), mental and linguistic verbs (think, promise, say, hoped), and elaborated verb phrases (using adverbs such as happily, angrily, sadly) (KMA, p. 217)
What is self-assessment?
the understanding of the thinking process and the ability to consciously consider and reflect on knowledge and understanding of one's self and others (Paul, p. 450).
Name some temporal connectives.
then, next, after that, while, after (KMA, p. 216)
What is the L4L stage?
this is the language for learning period, when many of the oral language bases for school success, including the knowledge of special classroom-discourse rules, decontextualized language, metalinguistic and phonological awareness, and literacy skills must be acquired in order for the student to meet the needs of the classroom; it is beyond the developing language phase, with skills above Brown's stage V (Paul, p. 417-8)
What is TD?
typically-developing (KMA, p. 203)
What are some hybrid intervention strategies for syntax concerning integrating expression/comprehension?
use classroom literature, provide opportunities for both comprehension and production of target forms such as passive sentence forms (Lecture 2.6; Hybrid intervention slide)
What are some hybrid intervention strategies for semantics concerning semantic integration and inferencing?
use literature-based activities, prediction activities, questions after short stories, puzzle questions/context cues, create sentence connections (Lecture 2.6, Hybrid intervention slides)
What are some deficits in pragmatics that are common to those with ASD?
use of language is a primary deficit; fail to develop a range of communicative functions; routines further limit communicative growth; use is typically to direct behavior (no initiation); other skills negatively effected are gaze interaction, proto-declaratives, and proto-imperatives (Lecture 2.5)
What are proto-imperatives?
used to get an adult to do or not do something, which includes requests for objects, requests for action, and rejections or protests (Paul, p. 244)
Name two ways to establish cohesion within a narrative.
using appropriate connectives and proper pronoun usage(KMA, p. 216)
What are implicit propositions?
using nonspecific referents (this, thing, that) as well as the overuse of pronouns that are unclear
What are some hybrid intervention strategies for syntax concerning the development of literate language syntax?
using noun phrase elaboration, verb phrase elaboration, and auxiliary verb marking (Lecture 2.6; Hybrid intervention slide)
What is referential cohesion?
using the appropriate pronouns and referents (KMA, p. 216)
What is a nonthematic proposition?
utterances that did NOT contribute to central development of the theme or main topic (KMA, p. 214).
What is language content like for those with ASD?
vocabulary scores tend to be consistently depressed, but for a substantial minority, receptive vocabulary is at a "peak of ability"; some say that the underlying organization of the semantic system is atypical and impoverished (Paul, p. 121).
What is a current level of functioning?
what the learner can do unaided (Lecture 2.6, What is Dynamic Assessment? slide)
What is the zone of proximal development?
what the learner can do with guidance (Lecture 2.6, What is Dynamic Assessment? slide); the distance between a child's current level of independent functioning and potential level of performance; defines what the child is able to learn with some help from a competent adult; the probable range or the ZPD is based on detailed assessment data, which pinpoints where the child is already functioning and on knowledge of normal development which allows us to determine the next few pieces of language development to fall into place (Paul, p. 66-67)
What is leap frogging?
when events are NOT chronologically-ordered in a personal narrative (KMA, p. 214)
What are some hybrid intervention strategies for syntax concerning advanced morphology?
work on derivational morphological knowledge because it is related to reading and spelling success in the upper elementary grades and beyond; as grade level increases, 60% of new words are morphologically complex (Lecture 2.6; Hybrid intervention slide)
What are some hybrid intervention strategies for semantics concerning word finding?
you can deepen word meaning; use visual maps, familiar scripts, massed practice, phonological cues, and metalinguistic reinforcement, phonemic neighbor cues, and rehearsal (Lecture 2.6, Hybrid intervention slides; Paul, p. 497)
How would you assess semantics in the L4L stage?
you would look at receptive vocabulary which consists of instructional vocabulary and textbook vocabulary, expressive vocabulary that looks at lexical diversity and word retrieval, and other semantics (Lecture 2.6)
How would you assess expressive syntax in the L4L stage?
you would use standardized tests and a language sample; you could look at disruptions such as false starts and excessive revisions (Lecture 2.6)
How would you assess receptive syntax and morphology in the L4L stage?
you would use standardized tests to look at these skills broadly, then you could use criterion-referenced tests to get a more narrow view such as decontextualized methods (judgment of semantic acceptability and judgment of appropriate interpretation), assessment of comprehension strategies and in contextualized settings (Lecture 2.6)
