Feasibility study of implementation of a customer satisfaction monitoring system (CSMS) in the public library from a management perspective

The present study examined the public librarians’ perceptions of the level of readiness for implementation of a customer satisfaction monitoring system (CSMS) in a public library from a management perspective. The researchers adopted a descriptive survey design for the study. The statistical population consisted of all librarians working in the central library of Astan Quds Razavi (285 people) of which 165 people (based on Krejcie-Morgan sample size table) were randomly selected. A researcher-made questionnaire was used to collect information. After electronic distribution and collection of questionnaires (through office automation system) and elimination of incomplete ones, 123 completed questionnaires were statistically analyzed. The findings of this study showed that the respondents enjoy a desirable level of all four managerial dimensions including strategic planning, organizational culture, internal marketing and project management for implementation of CSMS in the library. The present study also makes some recommendations to improve the current conditions based on the findings

Preguntas de opción múltiple versus preguntas de respuesta muy breve en la evaluación de estudiantes de patología veterinaria

Background: Well-developed assessment methods have a positive impact on students’ performance, and higher education institutes are usually encouraged to establish and use effective assessment methods that effectively enhance the learning process. Objectives: This study was designed to compare students’ performance in multiple choice questions (MCQs) including best single answer (BSA) and multiple true and false (MTF) types, and very short answer (VSA) questions, and to evaluate gender differences and feedback from students and faculty. Materials and methods: A test containing three different types of questions, BSA, MTF and VSA questions (10 each), was delivered to eight groups of veterinary pathology students (3rd level, Faculty of Veterinary Medicine, Assiut University, Assiut, Egypt) in April 2022. Students’ performance, test reliability and gender differences as well as feedback from students and faculty were evaluated. Results: Students did a significant higher performance in BSA and MTF questions compared to VSA questions. The reliability of BSA, MTF and VSA questions between different groups of students were 0.53, 0.52 and 0.13, respectively. Girl students achieved a higher performance in the whole test compared to boy students. Both boy and girl students showed nearly similar performance in BSA and MTF questions. However, girl students got significant higher score in VSA questions compared to boy students. Students’ and faculty opinions were in favor of BSA and MTF questions. Conclusion: Students did much better in MCQs than VSA questions. BSA and MTF questions are preferentially favored by students and faculty. &nbsp

The "Needle-splint" Technique: A Method of Accurate Apposition and Eversion during Microvascular Anastomosis.

We present the "needle-splint" technique, a microsurgical suturing technique that enhances micro-suturing technique, while ensures finer apposition and vessels walls eversion during the placement of sutures in microvascular anastomosis. This report demonstrates the usefulness of this technique in simple interrupted, continuous-interrupted, or multi-loops microsurgical suturing. It further allows direct visualization of the intra-wall-edges space and intimal sutures surface and could be utilized as a safety stabilizer to errors as it allows optimal vessels alignment while the needle curvature is acting as a "pusher" to separate the posterior wall during knot tying

Survey of Bibliotherapy in Hospital Libraries of Iran Based on SWOT Model

Abstract Purpose: The present study was performed with aim to survey bibliotherapy in hospital libraries of Iran based on SWOT model. Methods / Approach: The current applied research has been conducted through a survey method. The statistical population of the study consisted of 30 librarians and managers of 14 hospital libraries in Iran. The research tool was a researcher-made questionnaire consisting of 7 dimensions and 80 questions. Its validity was confirmed by experts and its reliability was confirmed by Cronbach\u27s alpha coefficient. Results: Hospital libraries of Mashhad had strength in 19 components and had basic weakness in 31 components. Also, the most important opportunities for hospital libraries were: the presence of new advances in the field of information technology, the impact of increased numer of educated people and the level of community literacy on bibliotherapy, the presence of young and specialized staff in the country; and the most important threats were: an increase in the inflation rate of the community, no attention of the Ministry of Health officials to book and bibliotherapy. Conclusion: Although the value and position of bibliotherapy are obvious to librarians, but the existing problems have caused that bibliotherapy was not be able to get the required place in the planning of libraries

Topic particles in the North Hail dialect of Najdi Arabic

PhD ThesisThis thesis investigates a set of clause-initial discourse particles in North Hail Arabic (NHA), a dialect spoken in Saudi Arabia. The particles are shown to be heads in the C-domain with topic-marking function. It is shown that the topics typology put forward by Frascarelli and Hinterhölzl (2007) for German and Italian extends to NHA. The Shifting Topic (S-Topic) is situated above the Focus Phrase, followed by Contrastive Topic (C-Topic), which is in turn followed by Familiar Topic (F-Topic). S-Topic can be marked by either C-particles mar or ʕad. The particles tara and ʔaktɪn mark an entity expressing C-Topic, while the particle ʁedɪ, tsin, ʔeʃwa and tigil mark an entity expressing F-Topic. All particles are argued to carry a valued [TOP] feature. However, they are different with respect to whether they have φ-content. This difference motivates the distinction between agreeing particles (having φ-content) and non-agreeing particles (not having φ-content). The study shows that the agreeing particles are probes, being with unvalued φ-features, establishing an Agree relation (Chomsky 2000, 2001) with the element that carries a matching unvalued [TOP] feature and valued φ-features. This results in the valuation of the unvalued φ-features of the agreeing particle, and the valuation of the matching unvalued [TOP] feature of the goal. As a result, the topic interpretation is achieved via the chain created by the head of the topic and the topicalized item. The study shows that when the goal has φ-content, an inflectional suffix expressing the same φ-content as that of the goal is suffixed to the particle. The motivation behind counting the [TOP] feature on the goal to be unvalued comes from the cases where the goal is the object. NHA data show that the object moves to a position where it gets accessible to the probe, the agreeing particle, following Chomsky (2000, 2001), Bošković (2007, 2014) and Holmberg et al. (2017). This is consistent in the case with multiple topics, where the two topics, the subject and the object, tuck in the projecting headed by the particle (Richards 1997, 1999). As for the non-agreeing particles, the study argues that, instead of φ-content, these heads are endowed with an [EPP] feature, which attracts the element carrying the matching unvalued [TOP] feature to the Spec position of the relevant head. This accounts for why such particles cannot be clause-initial. These facts motivate the assumption that movement to the left periphery (i.e. topicalization) is forced when the head of the Topic Phrase is not endowed with any φ-content

Cod liver oil/honey mixture: An effective treatment of equine complicated lower leg wounds 1 2

Abstract Wounds are of great concern in animals as they affect animal productivity and their treatment represents an economic burden to the owners particularly in developing countries. The present study investigated the beneficial role of a mixture of cod liver oil and honey in treatment of old wounds in equines. In which, 3 horses and 7 donkeys were admitted to the Veterinary Teaching Hospital at Assiut University, Assiut, Egypt with old wounds at the metacarpus (5 cases) and metatarsus (3 cases) and at the level of fetlock and carpal joints (one case each). Treatment of these wounds with cod liver oil/honey mixture markedly decreased their sizes and resulted in formation of a healthy scar after one month of treatment. To explain the mechanisms that underlie the effects of this mixture, 9 surgically-induced wounds at the metacarpus in 9 donkeys were treated with honey, cod liver oil or the mixture (3 wounds each) and compared with parallel untreated control wounds at the metatarsus. It was found that treatment of wounds with honey, cod liver oil and the mixture apparently decreased the size of wounds. Histopathological examination revealed that treated wounds with honey or cod liver oil showed complete epithelization over the wound areas. On the other hand, epithelization process was not complete in wounds treated with the mixture. Granulation tissue showed some variability between different treatments. Of which, wounds treated with the mixture showed a higher degree of maturity with increasing numbers of fibrocytes and parallel collagenous fibers. This could underlie the good results obtained in case studied wounds with the mixture. In conclusion, mixture of cod liver oil and honey is beneficial in treatment of old traumatized wounds in equine and this effect is primarily mediated by formation of healthy and mature scars. Cod liver oil or honey alone is beneficial for healing of recent and surgical wounds as they facilitate epithelization process

Expand Dimensional of Seismic Data and Random Noise Attenuation Using Low-Rank Estimation

Random noise attenuation in seismic data requires employing leading-edge methods to attain reliable denoised data. Efficient noise removal, effective signal preservation and recovery, reasonable processing time with a minimum signal distortion and seismic event deterioration are properties of a desired noise suppression algorithm. There are various noise attenuation methods available that more or less have these properties. We aim to obtain more effective denoised seismic data by assuming 3-D seismic data as a tensor in order three and increasing its dimension to 4-D seismic data by employing continuous wavelet transform (CWT). First, we map 3-D block seismic data to smaller blocks to estimate the low-rank component. The CWT of the tensor is calculated along the third dimension to extract the singular values and their related left/right vectors in the wavelet domain. Afterward, the effective low-rank component is extracted using optimized coefficients for each singular value. Thresholding is applied in the wavelet domain along the third dimension to calculate effective coefficients. Two synthetic and field data examples are considered for performance evaluation of the proposed method, and the results were compared with the competitive random noise suppression methods, such as the tensor optimum shrinkage singular value decomposition, the iterative block tensor singular value thresholding, and the block matching 4-D algorithms. Qualitative and quantitative comparison of the proposed method with other methods indicates that the proposed method efficiently eliminates random noise from seismic data

Surgical treatment and histopathology of different forms of olecranon and presternal bursitis in cattle and buffalo

Thirty seven cases of bursitis presented to our Veterinary Teaching Hospital from 2001 to 2005. There were 10 adult female buffalos with olecranon bursitis (one had bilateral bursitis) and 26 calves (7 cattle and 19 buffalos, 16 males and 10 females) with presternal bursitis. There were 10 out of 11 cases of olecranon bursitis and 21 out of 26 cases of presternal bursitis with different forms (cystic, proliferative and fibrous) that were removed surgically. The remaining 6 cases, cystic bursitis (olecranon = 1, presternal = 5), were treated by aspiration of their contents and injection of 4% iodine tincture intrabursally. Only 2 cases recovered, 3 cases progressed to fibrosis and required further surgical treatment 2 to 3 weeks later, and 1 case continued to have a cystic lesion. Histopathological examination of tissue specimens from different forms of bursitis revealed that the acquired bursae were generally lined with synovial-like membrane formed from 2-3 cellular layers that covered the connective tissue capsule. The connective tissue capsule differed from one type to another and consisted of fibrous tissues containing numerous small blood vessels, blood capillaries, lymphatics and nerves. There was also evidence for inflammation within the capsule represented by congestion of blood vessels and the presence of perivascular inflammatory cells, mostly mononuclear. In conclusion, surgical treatment was successful and effective for treatment of olecranon and presternal bursitis particularly for the chronic proliferative and fibrous form in cattle and buffalo. The histological structure of the acquired bursae was relatively similar consisting of a synovial-like membrane and a connective tissue capsule with varying degrees of the inflammatory process

Clinical and pathological assessment of different suture techniques for microvascular anastomosis in rat femoral artery

This study examined the clinical and pathological features after a microvascular anastomosis of a rat femoral artery using four different suture techniques. Sixty Sprage-Dawely rats were divided randomly into 4 groups. Fifteen bisected arteries (one from each animal) in Group I, II, III and IV were sutured with the simple interrupted suture, continuous suture, sleeve suture and cuff suture, respectively. The anastomosis times in Group I, II, III and IV were 28.67, 14.67, 15.47 and 15.93 min, respectively. Immediate bleeding that stopped without intervention (grade I) was observed in 67%, 73% and 60% of the anastomosed vessels in Groups II, III and IV, respectively, while 60% of the vessels in Group I showed light bleeding that was inhibited by gentile pressure (grade II). All vessels examined appeared to be patent at 5 and 15 min after the anastomosis. On the 7th day postoperatively, the vessels of Group I showed the highest patency rate (93%) compared with Groups II (67%), III (73%) and IV (87%). Moreover, there were more pronounced pathological changes in Group I than in the other groups. These changes included endothelial loss, endothelial proliferation, degeneration and necrosis of the tunica media. Suture materials surrounded by an inflammatory reaction were also observed. In conclusion, the simple interrupted suture is preferable for microvascular anastomosis due to its highest patency rate. The other techniques investigated can be good alternatives because of their short anastomotic time and moderate pathological changes

Chronic, low-dose rotenone reproduces Lewy neurites found in early stages of Parkinson's disease, reduces mitochondrial movement and slowly kills differentiated SH-SY5Y neural cells

<p>Abstract</p> <p>Background</p> <p>Parkinson's disease, the most common adult neurodegenerative movement disorder, demonstrates a brain-wide pathology that begins pre-clinically with alpha-synuclein aggregates ("Lewy neurites") in processes of gut enteric and vagal motor neurons. Rostral progression into substantia nigra with death of dopamine neurons produces the motor impairment phenotype that yields a clinical diagnosis. The vast majority of Parkinson's disease occurs sporadically, and current models of sporadic Parkinson's disease (sPD) can utilize directly infused or systemic neurotoxins.</p> <p>Results</p> <p>We developed a differentiation protocol for human SH-SY5Y neuroblastoma that yielded non-dividing dopaminergic neural cells with long processes that we then exposed to 50 nM rotenone, a complex I inhibitor used in Parkinson's disease models. After 21 days of rotenone, ~60% of cells died. Their processes retracted and accumulated ASYN-(+) and UB-(+) aggregates that blocked organelle transport. Mitochondrial movement velocities were reduced by 8 days of rotenone and continued to decline over time. No cytoplasmic inclusions resembling Lewy bodies were observed. Gene microarray analyses showed that the majority of genes were under-expressed. qPCR analyses of 11 mtDNA-encoded and 10 nDNA-encoded mitochondrial electron transport chain RNAs' relative expressions revealed small increases in mtDNA-encoded genes and lesser regulation of nDNA-encoded ETC genes.</p> <p>Conclusion</p> <p>Subacute rotenone treatment of differentiated SH-SY5Y neuroblastoma cells causes process retraction and partial death over several weeks, slowed mitochondrial movement in processes and appears to reproduce the Lewy neuritic changes of early Parkinson's disease pathology but does not cause Lewy body inclusions. The overall pattern of transcriptional regulation is gene under-expression with minimal regulation of ETC genes in spite of rotenone's being a complex I toxin. This rotenone-SH-SY5Y model in a differentiated human neural cell mimics changes of early Parkinson's disease and may be useful for screening therapeutics for neuroprotection in that disease stage.</p
