The influence of trust on attitude of employees towards HR Analytics in organisations

As business leaders increasingly recognize the importance of the ability to access and analyse the right information to support employee-related business decisions, and that the right talent is crucial in enhancing business strategies and competitive advantage, market demand for HR Analytics is on the rise, yielding an array of consequences. Among the consequences, companies need to access routine- and non-routine data from their employees to obtain the most informed analytics insights, requiring active participation of employees, which may not always be easy since they may be unwilling to share personal data. This paper highlights the need to encourage employee participation in HR Analytics, which derives greater value from employee survey efforts and contributes to competitive advantage. Consequently, this paper attempts to illustrate the circumstances in which a positive employee attitude towards HR Analytics can be obtained. As attitude originates from trust, this research considers trust in management (as specific individuals) and trust in the organisation (as en entity) as playing a central role in determining the overall level of employee-trust and thereby relevant in guiding attitudes. Distinguishing between three levels of trust; calculus-, knowledge- and identification-based trust, and three dimensions of attitude; affective-, behavioural- and cognitive attitude, the relationship between trust in management- and organisation, and attitude towards HR Analytics, is investigated. This paper finds significant evidence that although the relationship between trust in management and attitude towards HR Analytics is non-existent, attitude towards HR Analytics is rising chiefly at higher levels of trust in the organisation. Due to the relatively small pool of respondents and restricted research time frame, this paper offers a starting- point at suggesting that trust in an organisation, as an entity, is the most accurate indicator of attitude towards HR Analytics.
Multi-transmission-line-beam interactive system

We construct here a Lagrangian field formulation for a system consisting of an electron beam interacting with a slow-wave structure modeled by a possibly non-uniform multiple transmission line (MTL). In the case of a single line we recover the linear model of a traveling wave tube due to J. R. Pierce. Since a properly chosen MTL can approximate a real waveguide structure with any desired accuracy, the proposed model can be used in particular for design optimization. Furthermore, the Lagrangian formulation provides: (i) a clear identification of the mathematical source of amplification, (ii) exact expressions for the conserved energy and its flux distributions obtained from the Noether theorem. In the case of uniform MTLs we carry out an exhaustive analysis of eigenmodes and find sharp conditions on the parameters of the system to provide for amplifying regimes.
On the scientific name of the extant Giant Lizard of La
Gomera (Canary Islands): Gallotia gomerana Hutterer,
1985 vs. G. bravoana Hutterer, 1985 (Reptilia: Lacertidae)

Current published data on the scientific name of the extant Giant Lizard of La Gomera are discussed. We conclude that available information does not support the synonymy Gallotia gomerana = G. bravoana, so the extant giant lizards of La Gomera should be named as Gallotia gomerana while Gallotia bravoana must be maintained for the larger extinct species of this island.
Investigating the Interpersonal and Textual Meaning of Steve Jobs’ Stanford Speech in Terms of Hyland’s Metadiscourse Theory

Despite his remarkable influence on IT industry and on our daily lives, Steve Jobs’ speeches have seldom been researched. This paper sets out to explore the interpersonal and textual meaning of Jobs’ famous Stanford speech in light of Hyland’s theory of metadiscourse (2005). Hyland (2005) categorizes metadiscourse resources into interactional metadiscourse resources and interactive metadiscourse resources. By analyzing the interactional and interactive metadiscourse resources found in Jobs’ Stanford speech, the interpersonal and textual meaning of the speech is clearly revealed. It can be concluded that by the elaborate use of various metadiscourse resources, Steve Jobs successfully projects his ideas and supports his position, and at the same time, builds a good relationship with the audience and achieve mutual communication. This article also argues that Hyland’s categorization of metadiscourse, as a significant analytical framework in discourse analysis, offers a promising application in exploring interpersonal and textual meaning of language.
Single Nucleotide Polymorphisms in PEMT and MTHFR Genes are Associated with Omega 3 and 6 Fatty Acid Levels in the Red Blood Cells of Children with Obesity

Polyunsaturated fatty acids (PUFAs) play important roles in health and disease. PUFA levels are influenced by nutrition and genetic factors. The relationship between PUFA composition in red blood cells (RBCs) and genetic variations involved in PUFA metabolism has not been investigated in children with obesity. This study evaluated the association between several genetic variations and PUFA levels in RBCs in children with obesity. One hundred ninety-six children with obesity (101 females, 95 males) were evaluated using anthropometric measurements, dietary intakes, plasma and RBC PUFA quantification, blood biochemistry, and 55 single nucleotide polymorphisms within 14 genes. phosphatidylethanolamine N-methyltransferase (PEMT) rs1109859 and methylenetetrahydrofolate reductase gene (MTHFR) rs4846052 genotypes were associated with PUFA levels in RBCs. PUFA intake did not influence the RBC eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) levels. Higher RBC DHA and EPA levels were observed for PEMT rs1109859 GG and GA genotypes versus the AA genotype. Higher levels of RBC DHA, EPA, arachidonic acid (ARA), and linoleic acid (LA) and were observed for MTHFR rs4846052 TT genotype versus TC and CC genotypes. Genetic variations in PEMT rs1109859 and MTHFR rs4846052 were associated with different PUFA levels in RBC membranes and are estimators for PUFA species in RBCs. Further research is needed to establish whether these genotype-specific alterations are specific to overweight children.
The Canadian Shift: Its Acoustic Trajectory and Consequences for Vowel Categorization

The Canadian Vowel Shift (CS), generally described as a systematic lowering and backing of the front lax vowels (/ ɪ , ɛ , ae/; as in KIT , DRESS , and TRAP ), has been investigated by several researchers over the last two decades (see Boberg 2005, 2008, 2010; Clarke, Elms & Youssef 1995; Hoffman 2010; Labov, Ash & Boberg 2006; Roeder & Jarmasz 2010; Sadlier- Brown & Tamminga 2008, among others). Using apparent-time comparisons of older and younger Canadians’ vowel spaces, these studies do not always agree on the acoustic trajectory of the CS, notably whether the front lax vowels are principally receding and/or lowering; perhaps these disagreements are unsurprising given the ongoing nature of the vowel shift, the variety of birth years interviewed, and the studies’ methodological differences and diverse locales. Boberg (2005) found / ɛ / to be retracting and /ae/ to be lowering and then retracting in the speech of Anglophone Montrealers; this paper addresses the current apparent-time trajectory of the CS in one Montreal community. In addition, though several studies have investigated the CS in vowel production, nearly none (save De Decker 2010) have probed its effect on the perceptual categorization of vowels. This paper also introduces a perception experiment carried out with the same participants interviewed for production data.
Effects of Aromatherapy Combined with Music Therapy on Anxiety, Stress, and Fundamental Nursing Skills in Nursing Students: A Randomized Controlled Trial

Purpose: Nursing students often experience anxiety and stress when taking exams that test their fundamental nursing skills. Complementary alternative methods, such as aromatherapy and music therapy, have effectively alleviated such negative emotions among nursing students. However, few studies have examined the effects of combined therapy interventions or compared the effects of different interventions. This study identified the individual and combined effects of aromatherapy and music therapy on test anxiety, state anxiety, stress, and fundamental nursing skills among nursing students in Korea. Methods: A double-blinded, randomized, controlled trial design was used. The study was conducted at the nursing college at Sungshin Women’s University, Seoul, Republic of Korea. Ninety-eight sophomore female nursing students participated in the study. Subjects were randomly categorized under three groups: aromatherapy (n = 32), music therapy (n = 32), and aromatherapy combined with music therapy (n = 34). Aromatherapy was carried out through the inhalation method using an aroma lamp and three drops of Origanum majorana and Citrus sinensis. Music therapy was carried out using Beethoven’s Moonlight Sonata. Twenty-minute interventions were performed in separate rooms before an exam was administered. Data were collected through self-report questionnaires, including demographics, test anxiety, state anxiety, and stress. Participants’ Foley catheterization skill was likewise evaluated. Results: Aromatherapy combined with music therapy had a significant effect on test anxiety (F = 4.29, p = 0.016), state anxiety (F = 4.77, p = 0.011), stress (F = 4.62, p = 0.012), and performance of fundamental nursing skills (F = 8.04, p = 0.001) compared with aromatherapy and music therapy as separate interventions. Conclusions: The results suggest that nursing education that includes aromatherapy combined with music therapy may be effective for improving the performance of fundamental nursing skills and reducing anxiety and stress among nursing students.
Distributed Estimation Techniques for Cyber-Physical Systems: A Systematic Review

This paper undertakes a systematic review (SR) on distributed estimation techniques applied to cyber-physical systems (CPS). Even though SRs are not the common way to survey a theme in the control community, they provide a rigorous, robust and objective formula that should not be always ignored. The presented SR incorporates and adapts the guidelines recommended in other fields (mainly biosciences and computer sciences) to the field of automation and control and presents a brief description of the different phases that constitute an SR. As a result, this review compares the different techniques found in the literature in terms of: The proposed estimator (Kalman filter, Luenberger observer, Bayesian filter, etc.), the particular application within CPS, the design of the estimators (decentralized vs centralized), the amount of data required for implementation or the inclusion of experiments/simulations in the studies. Particular attention is paid to those papers that present some results in applications that include humans, animals or biological systems.
Deep-learning-based risk stratification for mortality of patients with acute myocardial infarction

Objective Conventional risk stratification models for mortality of acute myocardial infarction (AMI) have potential limitations. This study aimed to develop and validate deep-learning-based risk stratification for the mortality of patients with AMI (DAMI). Methods The data of 22,875 AMI patients from the Korean working group of the myocardial infarction (KorMI) registry were exclusively divided into 12,152 derivation data of 36 hospitals and 10,723 validation data of 23 hospitals. The predictor variables were the initial demographic and laboratory data. The endpoints were in-hospital mortality and 12-months mortality. We compared the DAMI performance with the global registry of acute coronary event (GRACE) score, acute coronary treatment and intervention outcomes network (ACTION) score, and the thrombolysis in myocardial infarction (TIMI) score using the validation data. Results In-hospital mortality for the study subjects was 4.4% and 6-month mortality after survival upon discharge was 2.2%. The areas under the receiver operating characteristic curves (AUCs) of the DAMI were 0.905 [95% confidence interval 0.902–0.909] and 0.870 [0.865–0.876] for the ST elevation myocardial infarction (STEMI) and non ST elevation myocardial infarction (NSTEMI) patients, respectively; these results significantly outperformed those of the GRACE (0.851 [0.846–0.856], 0.810 [0.803–0.819]), ACTION (0.852 [0.847–0.857], 0.806 [0.799–0.814] and TIMI score (0.781 [0.775–0.787], 0.593[0.585–0.603]). DAMI predicted 30.9% of patients more accurately than the GRACE score. As secondary outcome, during the 6-month follow-up, the high risk group, defined by the DAMI, has a significantly higher mortality rate than the low risk group (17.1% vs. 0.5%, p < 0.001). Conclusions The DAMI predicted in-hospital mortality and 12-month mortality of AMI patients more accurately than the existing risk scores and other machine-learning methods.
BANK LOANS AND SMALL MEDIUM ENTERPRISES’ (SMES) PERFORMANCE IN LAGOS, NIGERIA

The study examined the link between bank loan (measured by access to loan and debt financing) and Small and Medium Enterprise (SME) performance (measured by business expansion and output) in Lagos, Nigeria. The study adopted the survey research design. The population for this study consists of 11,663 SMEs in Lagos State, Nigeria. The Yamane sample size determination formula was employed, which gave a sample size of 372. The survey research design was adopted in carrying out the study, through the administration of structured questionnaire to selected chief executives of SMEs in Lagos. Two hypotheses were formulated and Pearson correlation analysis was employed to ascertain the association between bank loan and SMEs performance. The findings revealed that access to loan is positively associated with business expansion of SMEs in Nigeria (r = 0. 801, p-value<0.05); also, debt financing is positively associated with outputs of SMEs in Nigeria (r = 0. 894, p-value<0.05). It is therefore concluded that bank loan is strongly associated with SMEs performance, particularly SMEs business expansion and output. The researchers recommend that Government should ensure active operation of the SME Credit Guarantee Scheme to improve credit providers’ exposure to longer term debt issued to SMEs. SMEs should also utilise debt financing opportunities to enhance their outputs.
Effect of Hands-On Learning Strategy on Senior Secondary School Students’ Achievement in Topographical Map Studies in Mayo Belwa Local Government Area, Nigeria

This study was propelled by the poor performance of senior secondary school students’ recorded in practical Geography examinations. In line with this, the study investigated the Effect of Hands-On Learning Strategy on Senior Secondary School Students’ Achievement in Topographical Map Studies in Mayo Belwa Local Government Area, Nigeria. Four null hypotheses were formulated to guide the study. The study adopted a quasi-experimental non-equivalent pre-test, post test control group design comprising two groups made up of one experimental group and a control group. Four schools and two hundred and five (205) SS III Geography students made up the sample size of the study. Four intact classes (two each) were randomly selected through balloting without replacement and assigned to experimental and control groups. The instrument used for data collection in this study was Topographical Map Achievement Test (TMAT), constructed by the researcher but structured in line with WAEC and NECO standardized test items in practical Geography. The validity of this instrument was established by two experts in Geography Education and Test and Measurement. The reliability of the instrument was established using Kendall tau ḇ statistic. A reliability index of 0.78 was obtained. Hypotheses one, two and three were tested using independent samples t-test statistic. While hypothesis four was tested using Analysis of Covariance (ANCOVA). The findings of the study revealed that there was a statistically significant difference in the mean scores of students taught topographical maps using hands-on learning strategy and lecture method. There was a statistically significant difference in the retention scores of students taught topographical maps using hands-on learning strategy and lecture method. There was no significant effect of gender on the achievement of students taught topographical maps using hands-on learning strategy. There was no significant interaction effect of treatment and gender on students’ achievement in topographical map studies Based on the findings of this study, it was recommended that geography teachers should use hands-on learning strategy as an alternative strategy or incorporate this strategy with other instructional methods in order to promote effective teaching learning outcomes of students in topographical map studies.
Synthesis, Spectroscopy and Electrochemistry in Relation to DFT Computed Energies of Ferrocene- and Ruthenocene-Containing β-Diketonato Iridium(III) Heteroleptic Complexes. Structure of [(2-Pyridylphenyl)2Ir(RcCOCHCOCH3]

A series of new ferrocene- and ruthenocene-containing iridium(III) heteroleptic complexes of the type [(ppy)2Ir(RCOCHCOR′)], with ppy = 2-pyridylphenyl, R = Fc = FeII(η5-C5H4)(η5-C5H5) and R′ = CH3 (1) or Fc (2), as well as R = Rc = RuII(η5-C5H4)(η5-C5H5) and R′ = CH3 (3), Rc (4) or Fc (5) was synthesized via the reaction of appropriate metallocene-containing β-diketonato ligands with [(ppy)2(μ-Cl)Ir]2. The single crystal structure of 3 (monoclinic, P21/n, Z = 4) is described. Complexes 1–5 absorb light strongly in the region 280−480 nm the metallocenyl β-diketonato substituents quench phosphorescence in 1–5. Cyclic and square wave voltammetric studies in CH2Cl2/[N(nBu)4][B(C6F5)4] allowed observation of a reversible IrIII/IV redox couple as well as well-resolved ferrocenyl (Fc) and ruthenocenyl (Rc) one-electron transfer steps in 1−5. The sequence of redox events is in the order Fc oxidation, then IrIII oxidation and finally ruthenocene oxidation, all in one-electron transfer steps. Generation of IrIV quenched phosphorescence in 6, [(ppy)2Ir(H3CCOCHCOCH3)]. This study made it possible to predict the IrIII/IV formal reduction potential from Gordy scale group electronegativities, χR and/or ΣχR′ of β-diketonato pendent side groups as well as from DFT-calculated energies of the highest occupied molecular orbital of the species involved in the IrIII/IV oxidation at a 98% accuracy level.

Habitat shifts of endangered species under altered climate conditions: importance of biotic interactions

Predicting changes in potential habitat for endangered species as a result of global warming requires considering more than future climate conditions; it is also necessary to evaluate biotic associations. Most distribution models predicting species responses to climate change include climate variables and occasionally topographic and edaphic parameters, rarely are biotic interactions included. Here, we incorporate biotic interactions into niche models to predict suitable habitat for species under altered climates. We constructed and evaluated niche models for an endangered butterfly and a threatened bird species, both are habitat specialists restricted to semiarid shrublands of southern California. To incorporate their dependency on shrubs, we first developed climate‐based niche models for shrubland vegetation and individual shrub species. We also developed models for the butterfly's larval host plants. Outputs from these models were included in the environmental variable dataset used to create butterfly and bird niche models. For both animal species, abiotic–biotic models outperformed the climate‐only model, with climate‐only models over‐predicting suitable habitat under current climate conditions. We used the climate‐only and abiotic–biotic models to calculate amounts of suitable habitat under altered climates and to evaluate species' sensitivities to climate change. We varied temperature (+0.6, +1.7, and +2.8 °C) and precipitation (50%, 90%, 100%, 110%, and 150%) relative to current climate averages and within ranges predicted by global climate change models. Suitable habitat for each species was reduced at all levels of temperature increase. Both species were sensitive to precipitation changes, particularly increases. Under altered climates, including biotic variables reduced habitat by 68–100% relative to the climate‐only model. To design reserve systems conserving sensitive species under global warming, it is important to consider biotic interactions, particularly for habitat specialists and species with strong dependencies on other species.
Rotavirus Burden, Genetic Diversity and Impact of Vaccine in Children under Five in Tanzania

In Tanzania, rotavirus infections are responsible for 72% of diarrhea deaths in children under five. The Rotarix vaccine was introduced in early 2013 to mitigate rotavirus infections. Understanding the disease burden and virus genotype trends over time is important for assessing the impact of rotavirus vaccine in Tanzania. When assessing the data for this review, we found that deaths of children under five declined after vaccine introduction, from 8171/11,391 (72% of diarrhea deaths) in 2008 to 2552/7087 (36% of diarrhea deaths) in 2013. Prior to vaccination, the prevalence of rotavirus infections in children under five was 18.1–43.4%, 9.8–51%, and 29–41% in Dar es Salaam, Mwanza and Tanga, respectively, and after the introduction of vaccines, these percentages declined to 17.4–23.5%, 16–19%, and 10–29%, respectively. Rotaviruses in Tanzania are highly diverse, and include genotypes of animal origin in children under five. Of the genotypes, 10%, 28%, and 7% of the strains are untypable in Dar es Salaam, Tanga, and Zanzibar, respectively. Mixed rotavirus genotype infection accounts for 31%, 29%, and 12% of genotypes in Mwanza, Tanga and Zanzibar, respectively. The vaccine effectiveness ranges between 53% and 75% in Mwanza, Manyara and Zanzibar. Rotavirus vaccination has successfully reduced the rotavirus burden in Tanzania; however, further studies are needed to better understand the relationship between the wildtype strain and the vaccine strain as well as the zoonotic potential of rotavirus in the post-vaccine era.
