Relationships Between Demographics, Adverse Childhood Experiences, and Compassion Fatigue in Volunteers

Volunteers are vital to the operation of human service organizations, but nonprofit organizations remain at risk of turnover and disruption of services due to compassion fatigue of volunteers. Researchers have gained insight with respect to adverse childhood experiences being related to compassion fatigue. The purpose of this quantitative, correlational study was to explore the relationship between volunteer demographics, adverse childhood trauma (ACEs survey), and compassion fatigue (Professional Quality of Life Compassion Fatigue subscale). Compassion fatigue resilience theory was the theoretical framework used for this study. Three research questions were used for the study, with data collection completed online via survey. Results were varied for the research questions. Multiple linear regression revealed that ethnicity (p=0.013) was related to compassion fatigue at a statistically significant level but gender, age, volunteer time, and education were not. Simple linear regression showed that ACE-SF score was related to ProQOL-5 CFS score at a statistically significant level (p = 0.003). ANCOVA results indicated no statistically significant differences in compassion fatigue by gender, ethnicity, or education level. Differences in compassion fatigue were found for some volunteer time groups, but these were not consistent. These findings fill a gap in the research on volunteerism as well as how personal factors are related to compassion fatigue. The results of this study may be used to improve organizational environments for volunteers serving in nonprofit organizations

Texture and mineralogy of beach sediments of Chavara and Manavalakurichi, South India - A comparative analysis

203-211Chavara and Manavalakurichi are the two important areas with heavy mineral deposits in India. Surface samples were collected from five locations, each from Chavara and Manavalakurichi, and were analyzed for their textural parameters and mineralogy. Sediments from both regions are characteristically fine and medium sand. Chavara (CH) sands are moderately well sorted, whereas Manavalakurichi (MK) sands are moderately sorted to moderately well sorted sediments. Linear discriminate functions (LDF) calculated using the textural parameters show deposition environments of aeolian and shallow marine. Ilmenite predominantly exists along with other heavy minerals such as zircon, sillimanite, rutile, monazite, leucoxene, and garnet. The heavy minerals show an increasing trend towards, but its grain size becomes finer and well sorted. The berm and upper foreshore regions shows high concentration of heavy minerals

Dense Model for Automatic Image Description Generation with Game Theoretic Optimization

Due to the rapid growth of deep learning technologies, automatic image description generation is an interesting problem in computer vision and natural language generation. It helps to improve access to photo collections on social media and gives guidance for visually impaired people. Currently, deep neural networks play a vital role in computer vision and natural language processing tasks. The main objective of the work is to generate the grammatically correct description of the image using the semantics of the trained captions. An encoder-decoder framework using the deep neural system is used to implement an image description generation task. The encoder is an image parsing module, and the decoder is a surface realization module. The framework uses Densely connected convolutional neural networks (Densenet) for image encoding and Bidirectional Long Short Term Memory (BLSTM) for language modeling, and the outputs are given to bidirectional LSTM in the caption generator, which is trained to optimize the log-likelihood of the target description of the image. Most of the existing image captioning works use RNN and LSTM for language modeling. RNNs are computationally expensive with limited memory. LSTM checks the inputs in one direction. BLSTM is used in practice, which avoids the problem of RNN and LSTM. In this work, the selection of the best combination of words in caption generation is made using beam search and game theoretic search. The results show the game theoretic search outperforms beam search. The model was evaluated with the standard benchmark dataset Flickr8k. The Bilingual Evaluation Understudy (BLEU) score is taken as the evaluation measure of the system. A new evaluation measure called GCorrectwas used to check the grammatical correctness of the description. The performance of the proposed model achieves greater improvements over previous methods on the Flickr8k dataset. The proposed model produces grammatically correct sentences for images with a GCorrect of 0.040625 and a BLEU score of 69.96

A novel Sigma–Delta based parallel analogue-to-residue converter

Animportant step in the residue number system(RNS) based signal processing is the conversion of signal into residue domain. Many implementations of this conversion have been proposed for various goals, and one of the implementations is by a direct conversion from an analogue input. A novel approach for analogue-to-residue conversion is proposed in this research using the most popular Sigma–Delta analogue-to-digital converter (SD-ADC). In this approach, the front end is the same as in traditional SD-ADC that uses Sigma–Delta (SD) modulator with appropriate dynamic range, but the filtering is doneby a filter implemented usingRNSarithmetic. Hence, the natural output of the filter is an RNS representation of the input signal. The resolution, conversion speed, hardware complexity and cost of implementation of the proposed SD based analogue-to-residue converter are compared with the existing analogue-to-residue converters based on Nyquist rate ADCsCochin University of Science and TechnologyInternational Journal of Electronics Vol. 96, No. 6, June 2009, 571–58

Dual-mode RNS based programmable decimation filter for WCDMA and WLANa

The recent trends envisage multi-standard architectures as a promising solution for the future wireless transceivers. The computationally intensive decimation filter plays an important role in channel selection for multi-mode systems. An efficient reconfigurable implementation is a key to achieve low power consumption. To this end, this paper presents a dual-mode Residue Number System (RNS) based decimation filter which can be programmed for WCDMA and 802.11a standards. Decimation is done using multistage, multirate finite impulse response (FIR) filters. These FIR filters implemented in RNS domain offers high speed because of its carry free operation on smaller residues in parallel channels. Also, the FIR filters exhibit programmability to a selected standard by reconfiguring the hardware architecture. The total area is increased only by 33% to include WLANa compared to a single mode WCDMA transceiver. In each mode, the unused parts of the overall architecture is powered down and bypassed to attain power saving. The performance of the proposed decimation filter in terms of critical path delay and area are tabulatedCochin University of Science and TechnologyCircuits and Systems, 2008. ISCAS 2008.
