Transformational leadership as a factor that decreases turnover intention: a mediation of work stress and organizational citizenship behavior

The purpose of this research is to examining the effect of transformational leadership on work stress, organizational citizenship behavior (OCB) and turnover intention, examining the effect of work stress on OCB and turnover intention and examining the effect of OCB on turnover intention. ,Data were collected using the survey method, with questionnaires and data analysis were done employing the WarpPLS with two approaches. This research finds the results of this study indicate that the higher the transformational leadership, the lower the work stress will be. The positive significant relationship might be because of direction or command given by the leaders to nurses at each meeting held regularly. ,The results of this study indicate that the higher transformational leadership, the lower the turnover intention will be even though it is not significant. The results of this study indicate that the higher the work stress, the lower the OCB, although not significant. ,Previous studies have not examined the relationship of the variables mentioned above, especially in Manado where the respondents have different cultures.
BROWNIAN MOTION MINUS THE INDEPENDENT INCREMENTS: REPRESENTATION AND QUEUING APPLICATION

This paper relaxes assumptions defining multivariate Brownian motion (BM) to construct processes with dependent increments as tractable models for problems in engineering and management science. We show that any Gaussian Markov process starting at zero and possessing stationary increments and a symmetric smooth kernel has a parametric kernel of a particular form, and we derive the unique unbiased, jointly sufficient, maximum-likelihood estimators of those parameters. As an application, we model a single-server queue driven by such a process and derive its transient distribution conditional on its history.
Characterization of the complete mitochondrial genome of the fork-tailed threadfin bream, Nemipterus furcosus (Spariformes, Nemipteridae) and phylogenetic analysis

Abstract The complete mitochondrial genome of the fork-tailed threadfin bream, Nemipterus furcosus, which belongs to the family Nemipteridae was first determined. The complete mitochondrial genome was 16,882 bp in size and encoded of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a control region. Nemipterus furcosus has a mitochondrial gene arrangement that is typical of vertebrates. Phylogenetic analysis using mitochondrial genomes of 11 related species revealed that N. furcosus formed a well-supported monophyletic group with the other Nemipteridae species. This mitochondrial genome provides a useful information for addressing taxonomic issues.

‘Home Rule is Rome Rule’: exploring anti-Home Rule postcards in Edwardian Ireland

In 1912, the British government introduced a Home Rule Bill to Parliament, proposing that Ireland be granted the right to self-govern. This Bill provoked widespread outrage in the Ulster province of Ireland, where most people were Protestant and felt strongly in support of the Union. To express their opposition to Home Rule, Ulster Unionists produced propaganda postcards to convince fellow Irish citizens, the British government and the British public of their cause. This paper analyses six examples of anti-Home Rule picture postcards produced by Ulster Unionists in Belfast between 1912 and 1914. It groups them into six themes – British patriotism; Ulster loyalism; Protestantism; Violence; Mockery of Irish Nationalists; and Comic relief – and uses multimodal critical discourse analysis to explore the ideologies and messages promoted by their iconography. It concludes that, while these postcards aimed to show Ulster as united in its common objective of stopping the Home Rule Bill, their broad range of rhetoric and semiotic resources, in fact, reflects the lack of political consensus across the province and forecasts some of the troubles to come. Nonetheless, it asserts that, despite their contradictions, their hugely emotive power, coupled with other propaganda resources, was successful at drawing attention to Ulster’s cause and putting the province into the spotlight.
The pitch vulnerability of a typical wave energy converter geometry based on Melnikov and Markov approaches

ABSTRACT Many wave energy converter (WEC) designs emerging over the recent years are floating cylindrical geometries with position-keeping mooring system. However, the dynamic stability of these novel floating structures under random sea states has not been investigated adequately. The Melnikov function model and the Markov process model are two efficient approaches providing quantitative predictions of capsizing. In this study, application of the two methods to a moored floating cylinder representing a generic WEC, has been explored to predict the risks of pitchpoling under random excitation. Using the Melnikov approach, the rate of phase space flux was evaluated to quantify the dynamic stability. This approach is compared with the Markov approach, which evaluates the mean first escape (capsize) rate to quantify the dynamic stability. The two methods are investigated through studies using various parameters. The similarity of their results and the differences of their approximations will be explored.
The Influence of Quench Interruption and Direct Artificial Aging on the Hardening Response in AA6082 during Hot Deformation and In-Die Quenching

The automotive industry is searching for lightweight solutions to meet emission regulations. Development of an integrated hot forming and in-die quenching process will leverage use of age-hardenable aluminum alloys with high specific strength for applications in volume car manufacturing. Quench interruption and direct artificial aging may reduce the cycle time in a die-quenching process. However, this alters the temperature exposure of the part and results in an altered precipitation and clustering sequence during hardening. To investigate the effect of modified precipitation and clustering on mechanical properties, the process has been simulated by application of a water-cooled compression tool to control the combination of a temperature drop and simultaneous deformation prior to aging. Extruded 4.6 mm thick AA6082 profiles were deformed during different quenching rates and directly transferred to subsequent artificial aging from various temperatures between room temperature and 200 °C. The results indicate insignificant changes of strength and elongation after direct aging from 200 °C compared to specimens cooled to room temperature before aging.
Next-generation sequencing yields the complete mitogenome of Niya chicken (Gallus gallus)

Abstract In this study, the complete mitochondrial genome sequence of Niya chicken (Gallus gallus) was obtained by using the next-generation sequencing technology for the first time. The complete mitogenome sequence of Niya chicken is 16,784 bp in length, containing 2 ribosomal RNAs, 13 protein-coding genes, 22 transfer RNA genes and a D-loop region. Our work provides a valuable source of data for phylogenetic studies and helps us to understand the maternal origins of the native chickens.
Accounting Personnel Quality, Audit Risk, and Auditor Responses

This study draws on human capital theory to measure the quality of accounting personnel based on their education level and investigate whether the education level of the client firm’s accounting personnel affects auditors’ assessment of audit risk by examining audit outcomes. It shows that auditors charge higher fees and are more likely to make audit adjustments for companies whose accounting personnel have a lower level of education. The relationship between the education level of accounting personnel and audit fees (audit adjustments) is robust to an instrumental variable model, an entropy balancing approach, and a difference-in-differences analysis. Audit firms strategically assign more experienced partners to audit companies whose accounting personnel’s average education levels are relatively low. Taken together, these findings suggest that the education level of clients’ accounting personnel affects auditors’ assessment of audit risk and audit outcomes.

A Design of Low-Power 10-bit 1-MS/s Asynchronous SAR ADC for DSRC Application

A design of low-power 10-bit 1 MS/s asynchronous successive approximation register analog-to-digital converter (SAR ADC) is presented in this paper. To improve the linearity of the digital-to-analog converter (DAC) and energy efficiency, a common mode-based monotonic charge recovery (CMMC) switching technique is proposed. The proposed switching technique consumes only 63.75 CVREF2 switching energy, which is far less as compared to the conventional switching technique without dividing or adding additional switches. In addition, bootstrap switching is implemented to ensure enhanced linearity. To reduce the power consumption from the comparator, a dynamic latch comparator with a self-comparator clock generation circuit is implemented. The proposed prototype of the SAR ADC is implemented in a 55 nm CMOS (complementary metal-oxide-semiconductor) process. The proposed architecture achieves a figure of merit (FOM) of 17.4 fJ/conversion, signal-to-noise distortion ratio (SNDR) of 60.39 dB, and an effective number of bits (ENOB) of 9.74 bits with a sampling rate of 1 MS/s at measurement levels. The implemented SAR ADC consumes 14.8 µW power at 1 V power supply.
Derivative Trading and Structural Breaks in Volatility in India: An ICSS Approach

Researchers argue that ignoring the structural breaks in the time-series variance can cause significant upward biases in the degree of persistence in estimated GARCH models. Against this backdrop, the present study empirically examines the effect of stock futures on the underlying stock’s volatility in India by incorporating the structural breaks with the help of ICSS test and AR (1)-GARCH (1, 1) model for 30 most liquid and actively traded underlying stocks and their associated futures contracts. The study period ranges from the 1st January 2000 or the listing date of the particular stock (whichever is prior) till 31st March 2019. The study contributes to the on-going debate regarding the effect of derivatives on the underlying stock market’s volatility in two ways. Firstly, by taking into consideration the breaks in the volatility and, secondly, studying the effect of single stock futures will allow us to evaluate company-specific response to futures trading directly. The study offers a mixed outcome for the stocks under consideration. However, there is evidence of a decline in unconditional volatility for the majority of the stocks. The overall findings indicate that trading in stock futures may not have any detrimental effect on the underlying stock’s volatility. <br>
Changes in safety of Working Conditions as a Result of Introducing 5S Practices

Changes occurring in the economic and social systems, often referred to as Industry 4.0, relate to the employment structure in the economy. More employees will find jobs in the services sector and creative industries. These changes create new threats. The non-physical working conditions and the mental health of the employees are becoming increasingly important. The purpose of the research results presented in the article is to identify and learn about the relationship between the implementation of 5S practices and the safety of working conditions. This will allow a better understanding of the phenomena accompanying the implementation of 5S practices and their impact on employees' health. This makes it necessary for researchers to identify the goals set before implementing 5S practices in the light of the working conditions and to analyze their actual and potential impact on employees' health. The authors conducted bibliographic studies, in-depth interviews with employees and managers of the company, and analyzed documentation on the implementation of 5S. The study used the case study method. The authors, as a result of the research, identified practices used in companies when implementing the 5S principles and they found that the implementations did not take into account the context of the working conditions and the impact of the implementations on the employees' physical and mental health. They also determined that the main goal of the implementations was to maximize work efficiency. Where the working conditions improved, it occurred as an unintended effect. The authors have identified areas that can improve the mental well-being and health of employees when implementing and using 5S practices.
The Philippines’ and Singapore’s Journeys towards Liberalised Electricity Supply Industries—Takeaways for Malaysia

Malaysia is in the process of liberalising its electricity supply industry (ESI) further, with the second reform series announced in September 2018. If everything goes as planned, Malaysia would be the third country in the Association of Southeast Asia Nations (ASEAN) to have a fully liberalised ESI after the Philippines and Singapore. A number of initiatives have been in the pipeline to be executed and a lot more will be planned. At this juncture, it is important for Malaysia to look for the best practices and lessons that can be learnt from the experience of other countries that have successfully liberalised their ESIs. Being in the same region, it is believed that there is a lot that Malaysia can learn from the Philippines and Singapore. This paper therefore presents and deliberates on the chronological development of the countries’ progressive journeys in liberalising their ESIs. The aim is to discern the good practices, the challenges as well as the lessons learnt from these transformations. Analysis is being made and discussed from the following four perspectives; legislative framework, implementation phases, market components and impact on renewable energy penetration. Findings from this study would provide useful insight for Malaysia in determining the course of actions to be taken to reform its ESI. Beyond Malaysia, the findings can also serve as the reference for the other ASEAN countries in moving towards liberalising their ESIs.
Rapid Prototyping of Species Classifiers using Deep Learning: A Guide for Non-Experts

Point 1: Deep learning algorithms are revolutionizing how hypothesis generation, pattern recognition, and prediction occurs in the sciences. In the life sciences, particularly biology and its subfields, the use of deep learning is slowly but steadily increasing. However, prototyping or development of tools for practical applications remains in the domain of experienced coders. Furthermore, many tools can be quite costly and difficult to put together without expertise in Artificial intelligence (AI) computing.Point 2: We built a biological species classifier that leverages existing open-source tools and libraries. We designed the corresponding tutorial for users with basic skills in python and a small, but well-curated image dataset. We included annotated code in form of a Jupyter Notebook that can be adapted to any image dataset, ranging from satellite images, animals to bacteria. The prototype developer is publicly available and can be adapted for citizen science as well as other applications not envisioned in this paper.Point 3: We illustrate our approach with a case study of 219 images of 3 three seastar species. We show that with minimal parameter tuning of the AI pipeline we can create a classifier with 87% accuracy. We include additional approaches to understand the misclassified images and to curate the dataset to increase accuracy.Point 4: The power of AI approaches is becoming increasingly accessible. We can now readily build and prototype species classifiers that can have a great impact on research that requires species identification and other types of image analysis. Such tools have implications for citizen science, biodiversity monitoring, and a wide range of ecological applications.
Supranutritional supplementation of vitamin E influences mitochondrial proteome profile of post-mortem longissimus lumborum from feedlot heifers

Supplementation of vitamin E improves beef colour stability by minimizing lipid oxidation-induced myoglobin oxidation. Mitochondria affect myoglobin redox stability, and dietary vitamin E influences mitochondrial functionality in skeletal muscles. Nonetheless, the influence of vitamin E on the mitochondrial proteome of beef skeletal muscles has yet to be investigated. Therefore, the objective of this study was to examine the effect of dietary vitamin E on mitochondrial proteome of post-mortem beef longissimus lumborum (LL) muscle. Beef LL muscle samples (24 hours post-mortem) were obtained from the carcasses of nine (n = 9) vitamin E-fed (VITE) (1000 IU vitamin E for 89 days) and nine (n = 9) control (CONT) (diet without supplemental vitamin E) heifers. The mitochondrial proteome was analysed using two-dimensional gel electrophoresis and mass spectrometry, and nine differentially abundant spots were identified. All the differentially abundant spots were over-abundant in CONT, and the proteins were electron transport chain enzymes (NADH dehydrogenase iron-sulphur protein 8, NADH dehydrogenase flavoprotein 2, and cytochrome c oxidase subunit 5B), metabolic enzymes (succinate-CoA ligase (ADP-forming) subunit beta; dihydrolipoyllysine-residue succinyltransferase component of 2-oxoglutarate dehydrogenase complex; pyruvate dehydrogenase protein X component), and enzymes involved in ATP regeneration (creatine kinase S-type). The low abundance of these proteins in VITE may decrease mitochondrial activity, resulting in low oxidative activity. These findings suggest that the strong antioxidant activity of vitamin E leads to less expression of mitochondrial oxidative enzymes in beef skeletal muscles. Keywords : Beef colour, lipid oxidation, mitochondrial enzymes
Product quality information in supply chains: a performance-linked conceptual framework applied to the Australian red meat industry

PurposeThis paper aims to address the association between the quality and quantity of information in supply chains and the costs and benefits of generating, using and sharing it.Design/methodology/approachThe authors’ conceptual framework draws on multiple disciplines and theories of the value and use of product information. Controllable aspects of information, its quality and quantity, are the focus of the study as drivers of firm and chain performance. Structural equation models of constructs at two stages of the Australian red meat supply chain are employed, using data from a survey of 81 sheep and cattle breeders and commercial producers.FindingsInformation quality influences performance more for some product attributes than others and is more influential than is information quantity. Information sharing for many attributes generates benefits only at high cost. Investment in measurement and transmission technologies is supported for intrinsic and extrinsic measures of quality. Differences in respondents' evaluation of information quality are interpreted as evidence of persistent chain failure.Originality/valueTo the authors' knowledge, this is the first attempt at quantifying and comparing the benefits and costs of information sharing across multiple stages of a supply chain and the first to assess quantitatively the role played by information quality and quantity in generating costs and benefits.
Determination of δ44/40Ca and δ56/54Fe in Geological Materials Combined with a Simplified Method for their Separation Using a Single TODGA Resin Column

A measurement procedure has been developed for the determination of δ44/40Ca and δ56/54Fe in geological samples by multi‐collector inductively coupled plasma‐mass spectrometry (MC‐ICP‐MS) and thermal ionisation mass spectrometry (TIMS), combined with a single TODGA resin column for their separation. Using the TODGA resin for separation of geological materials, Fe and Ca ions were eluted by using 8 ml of 1.5 mol l−1 HNO3 and 8 ml of 2 mol l−1 HCl, respectively, and their recovery was 99.7 ± 0.4% (n = 3) for the former and 99.4 ± 0.6% (n = 3) for the latter after removal of matrix and interfering elements using 12 ml of 6 mol l−1 HCl. This procedure was validated by the reference materials AGV‐2, BCR‐2 and BHVO‐2. Their Fe and Ca isotope data were comparable to their literature values, confirming a single column containing TODGA resin can be applied to the separation of Fe and Ca in geological samples for determination of their isotope ratios free of measurement bias.
Resolving complaints online: development and validation of customers’ perceived webcare scale

ABSTRACT In the quest for resolving customer complaints and attracting customers for online transactions, service providers have developed online response mechanisms. This mechanism generically termed as ‘webcare’. Despite widespread adoption of webcare by marketers, there is minimal understanding of its conceptualisation and measurement in the customer-centric perspective. One of the primary reasons for this is the lack of a psychometric scale that measures webcare efforts as perceived by customers. Thus, we formally define and develop a psychometric instrument that measures ‘webcare’ efforts of the marketers. Accordingly, we conceptualised and validated a three dimensional, 14-item psychometric tool measuring Consumers’ Perceived Webcare (CPW). From an academic perspective, the scale can contribute towards advancement in marketing and online service recovery literature. From a practitioner’s perspective, the study will help managers to efficiently manage the process of designing and executing online response strategies while trying to resolve customer complaints and attract customers online.
