The Impact of Labour Turnover on Small And Medium Scale Enterprises ( Smes ) Performance in Cross River State , Nigeria

Employees remain the core issue in labour turnover or retention, and their actions and behaviour have multiplier effects that have some impact on the firm’s performance. The study examined the impact of labour turnover on the performance of small and medium scale enterprises in the eighteen local government areas of Cross River State, Nigeria. The cross sectional survey research design was adopted for the study; while a two-stage sampling procedure involving simple random and judgmental sampling techniques were used in the elements selection. The Ordinary Least Square regression statistical technique was used in the test of research hypotheses. The study established that labour turnover has an inverse relationship with the firm’s performance. The study recommended that Management should create incentives and opportunity where an employee could be co-opted as co-owner of the business over the years and have the privilege and right to partake in the share of end of year profit or end of contract bonus, as this would build a strong sense of job security and employee’s commitment. Management should scrutinize and institute recruitment and selection processes which ensure that only workers whose interests, objectives and goals align with those of the firm are hired. Also the firm’s Manager should undergo training and development in skills and knowledge acquisition in igniting effective human resource practices through workshop, seminars, in-house courses etc.
1 J un 2 01 9 Finite-Time Analysis of Distributed TD ( 0 ) with Linear Function Approximation for Multi-Agent Reinforcement Learning

We study the policy evaluation problem in multiagent reinforcement learning. In this problem, a group of agents work cooperatively to evaluate the value function for the global discounted accumulative reward problem, which is composed of local rewards observed by the agents. Over a series of time steps, the agents act, get rewarded, update their local estimate of the value function, then communicate with their neighbors. The local update at each agent can be interpreted as a distributed consensus-based variant of the popular temporal difference learning algorithm TD(0). While distributed reinforcement learning algorithms have been presented in the literature, almost nothing is known about their convergence rate. Our main contribution is providing a finite-time analysis for the convergence of the distributed TD(0) algorithm. We do this when the communication network between the agents is time-varying in general. We obtain an explicit upper bound on the rate of convergence of this algorithm as a function of the network topology and the discount factor. Our results mirror what we would expect from using distributed stochastic gradient descent for solving convex optimization problems.
Shared Value Creation, Creative Tourism and Local Communities Development: The Role of Cooperation as an Antecedent

EnglishThe link between local value creation through creative tourism and local development isn´t completely understood in the literature. Specifically it is unclear how creative tourism is developed in the context of rural communities with few resources and without a clear view of the path to value creation. This research analyses cooperation as an antecedent to value creation, in the context of creative tourism, based on five cases collected in five countries through in-depth interviews with local stakeholders. Results show that communities are able to recognize their potentialities and to cooperate to create value, however they are unable by themselves to overcome barriers to entrepreneurial behaviour. Results highlight the role of external entities: consensus facilitator, guidance and access to technical and financial resources. portuguesO processo de criacao de valor baseado no turismo criativo nao esta suficientemente aprofundado na literatura. Especificamente, nao esta clara a formacao de destinos turisticos criativos no contexto das comunidades rurais, com poucos recursos e sem uma visao clara do caminho para a criacao de valor. Esta investigacao analisa a cooperacao como um antecedente da criacao de valor, no contexto do turismo criativo, com base em cinco casos coletados em cinco paises por meio de entrevistas em profundidade com stakeholders locais. Os resultados mostram que as comunidades sao capazes de reconhecer suas potencialidades e cooperar para criar valor, porem sozinhas sao incapazes de superar as barreiras ao comportamento empreendedor. Os resultados destacam o papel das entidades externas: facilitador de consenso, orientacao e acesso a recursos tecnicos e financeiros.

CUSTOMIZING USER SEARCH RECORDS USING RANDOM WALKS OVER USER LOG

In today’s world of technology, users are increasingly pursuing complex task-oriented goals on the Web, such as making travel arrangements, managing finances or planning purchases. Each step requires one or more queries, and each query results in one or more clicks on relevant pages. To support users in their long-term information quests on the Web, “Customizing User Search Records Using Random Walks Over User Log” helps to keep track of their queries and clicks while searching online. The aim is to organize a user’s historical queries into groups in a vibrant and automated fashion. Automatic identification of query groups is helpful for a number of different search engine components and applications, such as query suggestions, result ranking, query alterations, sessionization, and collaborative search. The existing approaches rely on textual similarity or time thresholds. In this paper, Jaccard coefficient and ATSP coefficient are used on user behavior when searching online. Then the approach based on probabilistic random walks over the user log outperforms timebased and keyword similarity based approaches to customize user search records in different query groups. This is the robust approach that leverage search query logs.
Inhibition of miR-34 b and miR-34 c enhances α-synuclein expression in Parkinson ’ s disease

Mounting evidence suggests that microRNA (miR) dysregulation contributes to neurodegenerative disorders including Parkinson’s disease (PD). MiR-34b and miR-34c have been previously shown to be down-regulated in the brains of patients with PD. Here, we demonstrate that miR-34b and miR-34c repress the expression of α-synuclein (α-SYN), a key protein in PD pathogenesis. Inhibition of miR-34b and miR-34c expression in human dopaminergic SH-SY5Y cells increased α-SYN levels and stimulated aggregate formation. Additionally, a single nucleotide polymorphism (SNP) in the 3’-UTR of α-SYN was found to lower the miR-34b-mediated repression of the protein. Our results suggest that down-regulation of miR-34b and miR-34c in the brain, as well as an SNP in the 3’-UTR of α-SYN can increase α-SYN expression, possibly contributing to PD pathogenesis.
When to use partitioned signature files for retrieving information in multimedia systems

Some techniques based upon the partitioning of the signature file have been considered for improving the performance of the basic signature file access method. The authors discuss the performance issues of this approach. They identify the systems that can take advantage of this extended scheme. The following problems associated with the existing signature file partitioning methods based on the superimposed coding technique are discussed: (i) the problem of reducing the number partitions that must be examined when processing queries and (ii) the problem of nonuniform accesses to partitions. It is shown that these methods are not appropriate for systems in which the objects have a relatively large number of words. Some areas which require further study are described. <<ETX>>
Chemical , physical and biological changes of white oat ensiled with different additives Alterações químicas , físicas e biológicas

This study evaluated the addition of inoculants on the aerobic stability, nutritional value, and fermentation and microbiological profiles of white oat silages (Avena sativa L.). The trial was carried out in a completely randomized design with three treatments and six replicates. The treatments consisted of three ensiling approaches: oat (O); oat with homofermentative bacterial inoculant (OB); and oat with bacterialenzymatic inoculant (OBE). The aerobic stability was 9 days for silage O and 14 days for silages OB and OBE. The non-fiber carbohydrates (NFC) decreased (16.67 to 14.05% DM) and the crude protein (CP) did not change (mean of 8.98% DM) during the aerobic exposure in all silages. The buffering capacity (BC) decreased, while pH and the ammonia nitrogen (NH3-N) increased during the aerobic exposure in all silages. Independent from the aerobic exposure period, BC of OBE silage was higher than O silage (29.67 vs. 24.80 meq/100 g DM). Lactic acid bacteria count in OB silage (7.83 log CFU/g) was higher than in O and OBE silages (5.24 log CFU/g, on average). Also, the OB silage showed high enterobacteria count compared to OBE silage (2.49 vs. 0.76 log CFU/g). The inoculation with Lactobacillus plantarum, Pediococcus acidilactici and amylase enzyme at the dose of 1×10 CFU/g does not improve the aerobic stability, nutritional value and the fermentation and microbiological profiles of oat silages.
A pr 2 01 3 Bohr ’ s absolute convergence problem for H p-Dirichlet series in Banach spaces

The Bohr-Bohnenblust-Hille Theorem states that the width of the strip in the complex plane on which an ordinary Dirichlet series ∑ n ann −s converges uniformly but not absolutely is less than or equal to 1/2, and this estimate is optimal. Equivalently, the supremum of the absolute convergence abscissas of all Dirichlet series in the Hardy space H∞ equals 1/2. By a surprising fact of Bayart the same result holds true if H∞ is replaced by any Hardy space Hp , 1 ≤ p <∞, of Dirichlet series. For Dirichlet series with coefficients in a Banach space X the maximal width of Bohr’s strips depend on the geometry of X ; Defant, García, Maestre and Pérez-García proved that such maximal width equal 1−1/Cot(X ), where Cot(X ) denotes the maximal cotype of X . Equivalently, the supremum over the absolute convergence abscissas of all Dirichlet series in the vector-valued Hardy space H∞(X ) equals 1−1/Cot(X ). In this article we show that this result remains true if H∞(X ) is replaced by the larger class Hp (X ), 1 ≤ p <∞. 1 Main result and its motivation Given a Banach space X , an ordinary Dirichlet series in X is a series of the form D = ∑ n ann −s , where the coefficients an are vectors in X and s is a complex variable. Maximal domains where such Dirichlet series converge conditionally, uniformly or absolutely are half planes [Re >σ], where σ=σc ,σu or σa are called the abscissa of conditional, uniform or absolute convergence, respectively. More precisely, σα(D) is the infimum of all r ∈ R such that on [Re > r ] we have convergence of D of the requested type α= c,u or a. Clearly, we have σc(D) ≤ σu(D) ≤ σa(D), and it can be easily shown that supσa(D)−σc (D) = 1 , where the supremum is taken over all Dirichlet series D with coefficients in X .

Research on the Effect of Entrepreneurship on Diversification and Capital Structure Strategy in Small and Medium-Sized Enterprises

Many scholars have thought that entrepreneurship has an important effect on improving enterprise competitive position and obtaining enterprise competitive advantage. Then, what effect does the entrepreneurship has on diversification and capital structure strategy? In this paper, entrepreneurship is classified into radical entrepreneurship and gradual entrepreneurship, enterprise performance into the overall financial performance and new product performance. On the basis of questionnaire survey, by exploratory factor analysis and structural equation modeling, the results show that the radical entrepreneurship is helpful to SMEs realizing diversification, however, the gradual entrepreneurship is helpful to specialized operation; Whether radical entrepreneurship or gradual entrepreneurship has little effect on capital structure strategy in SMEs; Diversification indirectly affects the overall financial performance through affecting the new product performance.
SPATIAL AND TEMPORAL CLASSIFICATION OF KERALA BASED ON TEMPERATURE HUMIDITY INDEX ( THI )

The study was conducted with the objectives to delineate THI zones in Kerala with respect to thermal comfort of dairy cattle. Daily meteorological data for the past ten years (from 2002 to 2011) was collected from thirteen different weather stations located in different agro ecological zones of Kerala. The ten year average of daily THI, temperature and humidity of each weather station and of the entire state of Kerala were calculated. Moving averages were used to find periods. The 60 day moving average of THI at all the thirteen weather stations for the past ten years were calculated. Altitude was found to have significant effect on THI (p<0.05). The present study suggests following linear equation to predict THI from altitude. THI = -0.0151 X Altitude in meters + 91.923 (R2 = 0.9339) There is similarity in pattern of THI in all zones and the highest THI period in Kerala is from 19-Feb to May 27(98 days).
Towards a Semantic Annotation of English Television News - Building and Evaluating a Constraint Grammar FrameNet

This paper introduces a new approach to solve the Chinese Pinyin-to-character (PTC) conversion problem. The conversion from Chinese Pinyin to Chinese character can be regarded as a transformation between two different languages (from the Latin writing system of Chinese Pinyin to the character form of Chinese,Hanzi), which can be naturally solved by machine translation framework. PTC problem is usually regarded as a sequence labeling problem, however, it is more difficult than any other general sequence labeling problems, since it requires a large label set of all Chinese characters for the labeling task. The essential difficulty of the task lies in the high degree of ambiguities of Chinese characters corresponding to Pinyins. Our approach is novel in that it effectively combines the features of continuous source sequence and target sequence. The experimental results show that the proposed approach is much faster, besides, we got a better result and outperformed the existing sequence labeling approaches.
Evidence Regarding Management ’ s Choice of Forecast Precision and Financial Statement Irregularities Yu –

Much prior research focuses on restatements arising from the misapplication of generally accepted accounting principles (GAAP) such that the original financial statements were incorrect at the time issued. This prior research documents evidence that higher litigation risk arising from restatements is associated with a lower propensity to make forecasts, less timely forecasts, and less precision in the forecast (Johnson et al., 2001; Baginski et al., 2002). Ettredge et al. (2013) find that restatement firms exhibit less precise and less optimistically biased management earnings forecasts in the post– restatement periods. This evidence suggests that managers of restatement companies exhibit risk–averting forecasting behavior following restatements.

Multithreading Issues on Contemporary PowerPC Microprocessors

Contemporary high performance microprocessors are moving beyond faster clocks and wider busses to meet the growing demands for computational power. Techniques such as multiple threads of execution and heterogeneous processing cores are becoming more mainstream bringing with them interesting challenges for operating system and application developers alike. Fast synchronisation algorithms and lockless data structures are finding increasing relevance when applied to applications and operating systems running on these microprocessors. In this Literature Review we seek to gain an understanding of the state of the art for these types of algorithms, contemporary microprocessors and the benchmarks used to quantify their performance. Armed with this we intend to develop a plan of research so that we might contribute to the body of knowledge through work in COMP6702 in Semester 2, 2006.
Screening for Liver and Colorectal Cancer among Automobile Mechanics in Ibadan North-East local Government Area , South-West Nigeria

Introduction Cancer can be regarded as a group of diseases characterized by abnormal growth of cells, able to invade adjacent tissues and even distant organs (Park, 1997). The growth of malignant tumors usually destroys surrounding tissues, induces increased blood vessels formation to supply nutrients to the multiplying cancer cells, and eventually may spread to distant tissues (metastasis). Cancer is widely perceived to be a disease of industrialized nations, but the emerging facts show that the majority of deaths from cancer occur in the developing world. Ferlay et al., (2008) estimated that about 1,234,000 new colorectal cancer were diagnosed in the world with less than 60% from developed countries. Screening had been identified as one of the effective ways of preventing colorectal cancer. Hewitson et al., (2008) documented that about15% to 25% of colorectal cancer deaths can be prevented by screening. Indeed, cancer screening could prove to be beneficial in terms of reducing the incidence of cancer as well as mortality especially among at risk population. Several studies have suggested that colorectal cancer screening could improve early detection and prompt resumption of treatment and eventually reduces mortality from colorectal cancer (Maxwell, 1999; Molina et al., 2003). However, attempts to detect malignance within population who are without the sign and symptoms of the tumor could be challenging. Regrettably, many people from different occupational and environmental settings, and within the myriad of population are living with one cancer episode or the other without noticing. Sometimes they will be diagnosed with late stage cancer when they seek medical care for any ailment cases other than cancer, and therefore do not receive effective cancer treatment (Xin et al, 2013).
A real-world , retrospective , observational study of dabigatran and rivaroxaban in Turkey : elderly patients receive inappropriately low dose of rivaroxaban

Thromboembolic complications are the most important outcomes of atrial fibrillation (AF). New oral anticoagulants (NOACs) have been presented to protect non-valvular AF patients from thromboembolic complications. In this study, we aimed to evaluate effectiveness and safety of NOACs and also reveal prescribing habits of physicians, retrospectively. NOACs and their effectiveness and safety retrospectively. Patients with non-valvular AF using either rivaroxaban or dabigatran were included in the study in five different tertiary centers. Patients were identified by scanning their medication reports. Appropriate patients were called and face-to-face interviews were done. Followups were carried out on the phone. 183 out of 201 identified patients, taking rivaroxaban and dabigatran, were reached. General clinical characteristics were not significantly different between drug groups. Vascular disease and persistent AF were significantly higher in the rivaroxaban group. The rate of low dose medication in the dabigatran group was higher compared to the rivaroxaban group. Average age of the patients taking low dose medication were prominently higher in both groups. Between high and low dose users of the dabigatran group, creatinine clearance (CrCl) were not differed. Among rivaroxaban group, CrCl of the low dose users were lower than of the high dose users. However, among low-dose-prescribed patients, only 6 out of 38 patients had a CrCl value in the range of 30-49 ml/min, revealing that remaining 32 patients were receiving inappropriately low rivaroxaban dose. The rate of all-cause mortality, thromboembolism and bleeding complications were not statistically significant between the medication groups. While prescribing NOAC for non-valvular AF patients, physicians seem to consider patients’ ages rather than CrCl values. In terms of protecting from thromboembolism, rivaroxaban and dabigatran seem to be equally effective and safe.
Study measuring elite athletes ’ body composition : A case study evaluating analysis techniques

The effective monitoring of athletes’ health and performance is becoming increasingly important. one example of this is in the use of body composition measures to monitor levels of body fat, muscle mass and bone mass. These factors can all be useful when assessing training loads, rehabilitation and recovery, and the general health and wellbeing of the athlete. While the ‘gold standard’ of body composition measurement involves the use of dual-energy x-ray absorptiometry (DXA), other techniques such as skinfold anthropometry (SFA) and bioelectrical impedance anthropometry are widely used; due to their relative low cost and ease of operation. The purpose of the current small-scale case study was to assess the comparability of a range of techniques frequently used to assess body composition in an elite athletic population. Three elite athletes (mean age = 20 ± 3yrs.; height = 1.79 ± 0.09m; mass = 76 ± 15kg) had their body composition assessed, as part of their regular monitoring, using SFA, DXA and two different BIA systems. Analysis revealed that BIA recorded very similar reading for fat mass and muscle mass to those of DXA, while SFA did not provide accurate results. If possible DXA techniques should be used to ensure accurate measurement of an athlete’s body composition. However, in DXA’s absence the results of this small scale case study indicate that BIA offers a useful alternative.
