Adding Compression to Block Addressing Inverted Indexes

Inverted index compression, block addressing and sequential search on compressed text are three techniques that have been separately developed for efficient, low-overhead text retrieval. Modern text compression techniques can reduce the text to less than 30% of its size and allow searching it directly and faster than the uncompressed text. Inverted index compression obtains significant reduction of its original size at the same processing speed. Block addressing makes the inverted lists point to text blocks instead of exact positions and pay the reduction in space with some sequential text scanning.In this work we combine the three ideas in a single scheme. We present a compressed inverted file that indexes compressed text and uses block addressing. We consider different techniques to compress the index and study their performance with respect to the block size. We compare the index against three separate techniques for varying block sizes, showing that our index is superior to each isolated approach. For instance, with just 4% of extra space overhead the index has to scan less than 12% of the text for exact searches and about 20% allowing one error in the matches.     

Examining the Structural Relationship of Chronic Illness,Physical Function,Life Satisfaction,and Social Support in the Development of Depression Among Filipino Elderly in Institutionalized Settings

Considering the increasing prevalence of chronic illness in the Filipino elderly, this study seeks to test a model that describes the relationship between chronic illness and depression and how this link might interact with physical functioning, life satisfaction, and social support. Structural equation modeling was used to examine the causalities among these variables. With the participation of 151 respondents, data were gathered using a five-part instrument consisting of the robotfoto, Katz Index of Independence in Activities of Daily Living, Life Satisfaction Checklist, Social Support Scale, and Geriatric Depression Scale. Data were analyzed using AMOS version 19. Results showed that the duration and number of present chronic illness will not lead to an increase in social support, although those things proved to have a negative effect on physical functioning and life satisfaction. Social support from the family also showed to have a direct impact on life satisfaction while social support from the caregivers revealed a negative effect on physical functioning. Life satisfaction had a negative influence on depression while other suggested variables have no impact on depression at all. Through this model examining the variables relating to depression, holistic care must be provided to manage not only the medical conditions of the elderly but also their physical, social, and psychological well-being.     

Enhancement and reduction of associative retroactive cue interference by training in multiple contexts

Retroactive cue interference refers to situations in which a target cue X is paired with an outcome in phase 1 and a nontarget cue Z is paired with the same outcome in phase 2, with less subsequent responding to X being seen as a result of the phase 2 training. Two conditioned suppression experiments with rats were conducted to determine whether retroactive cue interference is similarly modulated by a manipulation that influences retroactive outcome interference (e.g., extinction). Both experiments used an ABC renewal-like design in which phase 1 training, phase 2 training, and testing each occurred in different contexts. Experiment 1 found that training the target association in multiple contexts without altering the number of training trials during phase 1 decreased retroactive cue interference (i.e., increased responding consistent with the target association). Experiment 2 found that training the interfering association in multiple contexts without altering the number of interference trials during phase 2 increased retroactive cue interference (i.e., decreased responding consistent with the target association). The possibility of similar mechanisms underlying cue interference and outcome interference is discussed.     

Improving semistatic compression via phrase-based modeling

In recent years, new semistatic word-based byte-oriented text compressors, such as Tagged Huffman and those based on Dense Codes, have shown that it is possible to perform fast direct search over compressed text and decompression of arbitrary text passages over collections reduced to around 30–35% of their original size. Much of their success is due to the use of words as source symbols and a byte-oriented target alphabet. This approach broke with traditional statistical compressors, which use characters as source symbols and a bit-oriented target alphabet.     

Academic Life-support: The Self Study of a Transnational Collaborative Mentoring Group

In this paper, we examined the collaborative mentoring processes of a transnational network. A narrative approach was employed to explore the mentoring practices and experiences of 19 women involved in the CURVE-Y-FRiENDs (C-Y-F) network. Their mentoring practices go beyond transnational, ethnic, discipline, and university borders. The processes employed in the network can be conceptualized as pathways to professional relationships. The narratives of C-Y-F members illustrated collaborative mentoring as an expression of the personal and professional dimensions of support, which must be part of academic life. Collaborative mentoring relationships and discourse provided a response to the current inconsistencies in faculty mentoring practices and have implications for the ways in which administrations and faculty in general initiate more empathetic structures and procedures that better meet the mentoring needs of women and minority faculty in academia.     

Correlates of Geriatric Loneliness in Philippine Nursing Homes: A Multiple Regression Model

Numerous studies have been conducted worldwide about loneliness in older adults living in nursing homes and the factors associated with it. However, only a few studies have focused on social factors that may predispose these older adults to experience loneliness. The purpose of this study was to examine the interplay between and among loneliness, social isolation, social engagement, and life satisfaction among Filipino elderly (n = 180) recruited from government and nongovernment nursing homes in the Philippines. A multiaspect questionnaire, which included the UCLA Loneliness Scale, Revised Index for Social Engagement, Friendship Scale, and Life Satisfaction for the Third Age-Short Form was used to gather the needed data and information. Results of single and multiple regression analyses indicate an effect of the three factors (social isolation, social engagement, and life satisfaction) on loneliness with social isolation having the greatest impact on loneliness. Notably, increased social isolation, inadequate social engagement and decreased life satisfaction consequently aggravate loneliness. Social engagement produced a positive effect to both social isolation and life satisfaction in a way that a decrease in social engagement will decrease life satisfaction and increase social isolation. On the whole, loneliness in geriatric nursing homes is evident, and it is shaped by social isolation, social engagement and life satisfaction. Impliedly, interventions and measures to minimize loneliness are necessary, and further research is needed to explore other variables contributing to loneliness in geriatric nursing homes.     

Social isolation from communities and child maltreatment: a cross-cultural comparison

OBJECTIVE: The aim of this study is to determine: (1) the differences between Spanish and Colombian cultures in relation to community social support variables, and (2) the relationships between community social support variables and child maltreatment in both cultures. METHOD: The study was based on 670 nonabusive families and 166 abusive families. The parents were asked to complete the Community Social Support Questionnaire. This instrument measures community social support in terms of Community Integration and Satisfaction, membership in voluntary organizations and community participation, and use of Community Resources of Social Support. RESULTS: Differences between both cultures were found in the pattern of community social support for the nonabusive groups. However, the relationships between community social support and child maltreatment were similar cross-culturally. Our results indicate that in both cultures abusive parents show lower levels of community integration, participation in community social activities and use of formal and informal organizations than the parents that provide adequate care. CONCLUSIONS: The results largely support the literature that has repeatedly reported the link between social isolation and child maltreatment and they confirm this relation within two cultural contexts, Colombian and Spanish, quite different from the Anglo-Saxon context, where most of the previous studies have been carried out.     

Orphan Works at Theatre Library and Information Centres: Assessing Librarians' Perceptions and Management in Spain

Currently, libraries and other information services are facing new professional challenges in relation to digitization policies and orphan works after the publication of European Directive 2012/28/EU on certain permitted uses of orphan works and Spanish Royal Decree 224/2016. This paper aims to analyse how Spanish library and information centres specialising in theatre and performing arts meet users' textual and non-textual information needs, by respecting copyright issues and being involved in a dynamic and digital environment. For this purpose, an online questionnaire, which was used as a methodological tool, was sent to library directors in February 2018. At the same time, some research questions based on orphan works and digitisation approaches are discussed in the paper, specifically in reference to graphic and audiovisual materials.     

Filipino teachers’ experiences of supportive relationships with colleagues: A narrative-biographical inquiry

The purpose of this qualitative study is to explore teachers’ experiences of supportive relationships with colleagues. A total of fifty (50) public and private elementary and secondary school teachers in the central part of the Philippines were purposively selected as respondents. Guided by a narrative-biographical interview, results of the study yielded four significant themes that describe how Filipino teachers as relational people experience and interpret supportive relationships in the school setting. These include: supportive relationships as (1) a life-giving force; (2) an extension of one’s family; (3) a reciprocal process; and (4) a work still in progress. This paper is a segment of her dissertation entitled: Evolving a Continuum of Filipino Teachers’ Worldview of Pedagogy based on the Narrative-Biographical and Micro-Political Perspectives.     

So near and yet so far: a grounded theory study of incarcerated Filipino elderly’s experiences of emotional geography

ABSTRACT

Emotional geography defines how emotions affect the interaction of individuals within their setting. Considering that prison has been described as a place saturated with negative emotions, previous studies have only dwelt on the negative impact of incarceration on the emotional well-being and interactions of the inmates. However, no attempt has been made that dilates on how emotional geography facilitates the establishment of good relationships inside the penal institution, hence this investigation. The overall intent of this investigation is to describe the process of emotional geography among a select group of incarcerated Filipino elderly. This study utilized the qualitative, grounded theory design. A purposive sample of 25 incarcerated Filipino elderly from the New Bilibid Prison in Muntinlupa City, Philippines participated in this study. Interestingly, this study afforded the development of de Guzman, Henson, Gumba, Fradejas, and Valdez Shoelace Model of Emotional Geography which describes how the incarcerated Filipino elderly’s emotions affect their interactions in achieving positive relationships with other inmates while inside the penal institution. This emerged model is comprised of three phases, namely: isolating (embracing a wall of mistrust), integrating (making connections through shared stories), and intertwining (strengthening the bonds thru emotional understanding). The emerged theoretical model has successfully described the process of emotional geography, which can be utilized by gerontological workers, nurses and other health professionals in addressing and accommodating the social and custodial needs of this vulnerable group.
