The search interface is made of three sections: Search, Explore, and Results. These are described in detail below.
You may start searching either from the Search section or from the Explore section.
Search
This section shows your current search criteria and allows you to submit keywords to search in the bibliography.
Each new submission adds the entered keywords to the list of search criteria.
To start a new search instead of adding keywords to the current search, use the Reset search button, then enter your new keywords.
To replace an already submitted keyword, first remove it by unchecking its checkbox, then submit a new keyword.
You may control the extent of your search by selecting where to search. The options are:
Everywhere: Search your keywords in all bibliographic record fields and in the text content of the available documents.
In authors or contributors: Search your keywords in author or contributor names.
In titles: Search your keywords in titles.
In all fields: Search your keywords in all bibliographic record fields.
In documents: Search your keywords in the text content of the available documents.
You may use boolean operators with your keywords. For instance:
AND: Finds entries that contain all specified terms. This is the default relation between terms when no operator is specified, e.g., a b is the same as a AND b.
OR: Finds entries that contain any of the specified terms, e.g., a OR b.
NOT: Excludes entries that contain the specified terms, e.g., NOT a.
Boolean operators must be entered in UPPERCASE.
You may use logical groupings (with parentheses) to eliminate ambiguities when using multiple boolean operators, e.g., (a OR b) AND c.
You may require exact sequences of words (with double quotes), e.g., "a b c". The default difference between word positions is 1, meaning that an entry will match if it contains the words next to each other, but a different maximum distance may be specified (with the tilde character), e.g., "web search"~2 allows up to 1 word between web and search, meaning it could match web site search as well as web search.
You may specify that some words are more important than others (with the caret), e.g., faceted^2 search browsing^0.5 specifies that faceted is twice as important as search when computing the relevance score of the results, while browsing is half as important. Such term boosting may be applied to a logical grouping, e.g., (a b)^3 c.
Keyword search is case-insentitive, accents are folded, and punctuation is ignored.
Stemming is performed on terms from most text fields, e.g., title, abstract, notes. Words are thus reduced to their root form, saving you from having to specify all variants of a word when searching, e.g., terms such as search, searches, and searching all produce the same results. Stemming is not applied to text in name fields, e.g., authors/contributors, publisher, publication.
Explore
This section allows you to explore categories associated with the references.
Categories can be used to filter your search. Check a category to add it to your search criteria and narrow your search. Your search results will then only show entries that are associated with that category.
Uncheck a category to remove it from your search criteria and broaden your search results.
The numbers shown next to the categories indicate how many entries are associated with each category in the current set of results. Those numbers will vary based on your search criteria to always describe the current set of results. Likewise, categories and whole facets will disappear when the result set has no entry associated to them.
An arrow icon () appearing next to a category indicates that subcategories are available. You may press it to expand a list of more specific categories. You may press it again later to collapse the list. Expanding or collapsing subcategories will not change your current search; this allows you to quickly explore a hierarchy of categories if desired.
Results
This section shows the search results. When no search criteria has been given, it shows the full content of the bibliography (up to 20 entries per page).
Each entry of the results list is a link to its full bibliographic record. From the bibliographic record view, you may continue exploring the search results by going to previous or following records in your search results, or you may return to the list of results.
Additional links, such as Read document or View on [website name], may appear under a result. These give you quick access to the resource. Those links will also be available in the full bibliographic record.
The Abstracts button lets you toggle the display of abstracts within the list of search results. Enabling abstracts, however, will have no effect on results for which no abstract is available.
Various options are provided to let you sort the search results. One of them is the Relevance option, which ranks the results from most relevant to least relevant. The score used for ranking takes into account word frequencies as well as the fields where they appear. For instance, if a search term occurs frequently in an entry or is one of very few terms used in that entry, that entry will probably rank higher than another where the search term occurs less frequently or where lots of other words also occur. Likewise, a search term will have more effect on the scores if it is rare in the whole bibliography than if it is very common. Also, if a search term appears in, e.g., the title of an entry, it will have more effect on the score of that entry than if it appeared in a less important field such as the abstract.
The Relevance sort is only available after keywords have been submitted using the Search section.
Categories selected in the Explore section have no effect on the relevance score. Their only effect is to filter the list of results.
The incidence of self-injurious behavior (SIB) in children with Autism Spectrum Disorder (ASD) ranges from 35% to 60%. Common types of SIB include head-banging, hair-pulling, arm-biting, eye-poking, skin-scratching and other behaviors. Functional Behavior Assessment (FBA) and function-based behavioral interventions have been shown to reduce SIB in children with ASD. However, there is limited research on this subject in Macao. This study applies a single-subject alternating treatment design to conduct an FBA on the self-injurious behavior of a child with ASD in Macao, followed by the implementation of a function-based behavioral intervention, aiming to effectively reduce the frequency or intensity of SIB in children with ASD. Based on the results of this study, the conclusions are as follows: a) Based on the Functional Behavior Assessment, the main functions of self-injurious behavior in the child with ASD are identified as escape from task demands and access to tangible items; b) Function-based intervention strategies (such as functional communication training, FCT) significantly reduce the occurrence of SIB in children with ASD. In this case study, the frequency of SIB markedly decreased, and the improvement was maintained even after the intervention was withdrawn; c) Based on the results of FCT, both independent communication behaviors (picture cards and the speech-generating device BigMac) effectively reduced the child’s SIB. However, the child learned to use the BigMac as an alternative communication behavior more quickly, and there was no occurrence of self-injurious behavior while using BigMac, whereas SIB occasionally occurred when using picture cards; d) Function-based intervention strategies demonstrate a good social validity, with the child’s teachers expressing agreement with the research’s implementation process and outcomes.
自閉症譜系障礙（Autism Spectrum Disorder，ASD）兒童自傷行為的發生率高達35%-60%，常見的類型包括撞頭、拉頭髮、咬手臂、戳眼睛及抓皮膚等。功能行為評估和基於功能的行為干預有助於降低自閉症兒童的自傷行為，然而，澳門相關的研究較少。本研究採用單一被試交替處理設計對1名澳門自閉症兒童的自傷行為開展功能行為評估，並制定相應的基於功能的行為干預。研究結果顯示：a) 基於功能行為評估，可以確定該自閉症兒童自傷行為的主要功能為逃避任務及獲得實物；b) 採用基於行為功能的干預策略（即功能性溝通訓練），可以有效降低該自閉症兒童自傷行為的頻率，且在撤銷干預後仍能維持改善效果；c) 根據功能性溝通訓練的結果，學習兩種獨立溝通行為（圖卡和言語生成設備BigMac）均有助於減少該兒童的自傷行為，但相對而言，他更快學會使用BigMac這個替代溝通行為，而且在使用BigMac的實驗時段中完全沒有出現自傷行為，而使用圖卡時會出現自傷行為；d) 基於行為功能的干預策略具有良好的社會效度，該自閉症兒童的教師對研究的實施過程及成效表示認同。
