Antecedents and consequences of corporate communication management (CCM): an agenda for future research

Purpose This paper aims to provide a degree of clarity on the corporate communication management (CCM) concept, by building a conceptual framework that uncovers its underlying antecedents and consequences. Although it is consolidated that corporate communication and information together play an important role in strategic management planning because of the high relevance of managing positive relationships with multiple stakeholder that have a strong impact on corporate survival, extant literature suggests that there have been few empirical studies so far assessing the contribution of CCM to organisational performance. Design/methodology/approach The paper is conceptual, and a model is developed as a result of an extensive critical multidisciplinary literature review. Findings Findings of this study identify three antecedents of CCM, namely, culture, information and communication technology innovation diffusion and corporate leadership. In addition, the study highlights a potential positive relationship between CCM, financial performance and corporate mission achievement. An integrative conceptual framework and a detailed summary table are presented in the paper. Originality/value This study provides a comprehensive critical insight into a growing body of corporate communication and information business literature that offers the basis for a thorough assessment of CCM contribution to organisational performance. By doing so, it advances the body of applicable knowledge of corporate communication meant as a strategic management lever. Moreover, the managerial and policy implications provided in this paper may help corporate communication and information practitioners to identify the key guidelines for the design and implementation of an appropriate CCM programme.
Teaching and Learning Vocabulary through Reading as a Social Practice in Saudi Universities

The study explores the social practice of vocabulary learning by examining vocabulary teaching techniques employed by teachers, the vocabulary learning strategies (VLSs) identified by students as most useful and the ones they felt most competent in using when reading and teachers’ and students’ attitudes towards learning vocabulary through reading. While most vocabulary research is quantitative, this study used a mixed methods approach of quantitative and qualitative data collected from a range of sources. One hundred and fifty students majoring in English from four different universities completed a semi-structured questionnaire and twenty-two of them were interviewed. In addition, nine teachers of vocabulary and reading subjects were interviewed and their classes observed. A systematic analysis for the prescribed textbooks was also conducted. The findings revealed that both teachers and students were negotiating their autonomy on an ongoing basis, which means that the social context of learning has a powerful influence on what students learn. The study concludes that vocabulary learning is a social practice influenced by a range of factors, such as teaching techniques, VLSs, the prescribed textbook, participants’ beliefs and attitudes, learners’ interests, cultural values and learners’ level of competence in English.
Cancer of the Vulva — A Review

Cancer of the Vulva: a review In reporting on cancer of the vulva, we should keep in mind some important aspects of its epidemiology and its early detection. Most of the pa‐ pers on the subject refer to vulvar cancer as a rare disease, accounting for 4 to 5% of all malignant neoplasms of the female genital tract and less than 1% of women's cancers. The incidence varies from 1 to 3.6 cases per 100,000 women, with peak incidence at ages 70-79 years. Even though the incidence increases with age, the proportion of young patients with vulvar cancer has greatly increased due to its association with infection with human papillomavirus (HPV). The risk of developing cancer of the vulva is related to behavioral, reproductive, hormonal and genetic aspects. Factors that increase risk include other geni‐ tal cancers, chronic inflammatory diseases of the vulva, smoking, history of genital warts and vulvar intraepithelial neoplasia (VIN). We can consider that, given the epidemiologi‐ cal evidence, there are two etiologic pathways for vulvar cancer: one related to older pa‐ tients, in the seventh or eighth decades of life, associated with mutations in TP53 and non-neoplastic epithelial disorders such as chronic inflammation or vulvar lichen, shows precursor lesions of differentiated VIN; the other is more common in young patients, ac‐ counts for approximately 43-60% of squamous carcinoma of the vulva, is associated with HPV infection, and is a common precursor lesion of VIN. Eighty-five to ninety percent of vulvar cancers are squamous in origin (squamous cell carcinoma); however, when con‐ sidering the embryological origin of the vulva the three germ layers different histolog‐ ic types can compose neoplasms affecting the region.
Behaviour change techniques to facilitate physical activity in older adults: what and how

ABSTRACT Physical inactivity in older adults presents a significant problem within modern societies globally. Using a mixed-method approach, this study explored strategies for the development and delivery of physical activity (PA) interventions by investigating what behaviour change techniques (BCTs) are useful, and how these techniques should be implemented to be feasible for older adults. Sixty-six older adults completed a survey indicating the most useful BCTs, mapping on to motivational, volitional and automatic factors. Of these, 48 older adults participated in an interview exploring strategies for a PA intervention targeted at older adults. The most useful BCT identified in the survey was autonomy support (61.3%), followed by instruction to perform the behaviour (43.5%) and having a credible source of information about PA (42.6%). The key themes discussed in the interviews included providing support in making an informed choice, instruction on how to perform PA, information about health consequences, social support, goal setting, action and coping plans, behavioural demonstration and practice, and monitoring PA. The interviews also revealed key aspects of programme implementation including face-to-face delivery, followed up with additional materials; low cost; age-appropriate PA level; and individualised approach. Interventions assisting older adults in increasing their PA participation across a range of settings should incorporate BCTs targeting multiple processes, while tailoring their delivery to older adults’ preferences to ensure their feasibility in supporting regular PA engagement.
Properties of Hydraulic Jump over Apparent Corrugated Beds

The characteristics of hydraulic jumps were investigated for three shapes of artificial apparent corrugated beds in a horizontal rectangular flume. Rectangular, triangular, and circular-shaped tire waste corrugated beds were used. Froude number ranged from 2.75 to 4.25. The experimental observations included water surface profiles, bed shear stress, and the hydraulic jump length. Results showed that the shape of the corrugation had relatively insignificant effects on hydraulic jump properties for small Froude numbers. The rectangular, triangular, and circular-shaped corrugated beds reduced the hydraulic jump length by up to 7, 10, and 11%, respectively. The corrugated bed also reduced the tailwater depth by up to 11.5% compared with the smooth bed. The apparent conditions of corrugated bed reduced the hydraulic jump relative length and height by about 0.4 and 0.5, respectively. The circular-shaped tire waste was found to be more effective in reducing the length and depth of the hydraulic jump.
The Contribution of Different Risk Factors in the Occurrence of Stroke

Background: Although stroke cause substantial morbidity and mortality, it is unclear how individuals are affected, or a group of risk factors contribute to stroke outcomes especially in developing countries. Methods: This study evaluated the risk factors of stroke. This was a cross-sectional study of stroke patients from Komfo Anokye Teaching Hospital; Adult enrolees who were eligible for inclusion were persons who have had stroke within twenty-four hours of onset without any medication. Questionnaires were used to gather information on medical history, demographic features and lifestyle. The lipid profile, fasting blood sugar and blood pressure were measured, likewise the determination of aminotransferases and gamma-glutamyltransferase. Results: Out of 224 stroke patients, of mean age 65.64 ± 1.08 SEM years, used for the study, 56.7% of the patients had hyperglycaemia, whereas 47.2% were known diabetics. Hypertriglyceridaemiawas found in 55.8%, followed by 30.8% of the patients who had a reduced HDL-C and 17.95% of them with increased LDL-C. About 20% of the patients had raised AST, 7.1% raised ALT and 14.7% raised GGT above the normal levels. As high as 63% of stroke patients had high blood pressure. Conclusions: There were a high prevalence of both hypertension and hyperglycaemia among the stroke patients. Based on this study, it is important to stress the need for educating the stroke patients and/or their caregivers, on the aetiology of stroke and the treatment options. The general population should also be educated on primary preventive measures for all age groups and both genders.
Interactive comment on “ Rainfall-Runoff modelling using Long-Short-Term-Memory ( LSTM ) networks

This paper utilizes a data-driven approach, based on recurrent neural networks, to model rainfall-runoff relationships. A novel method is applied to model runoff in catchments in the continental U.S where gage data and meteorological forcings are available, and results are compared with existing process-based model results which are used as a benchmark. The LSTM method presented is tested through various experiments where the network is either trained for individual catchments, large aggregated regional catchments, or a combination approach where models are initialized based on large catchments and then “fine-tuned” to smaller catchments. This study is presented to introduce LSTM as an efficient hydrological modelling approach that is shown to provide similar quality predictions as an existing process-based model.
Revisiting the disappearance of terrestrial dissolved organic matter in the ocean: a δ 13 C study

Organic carbon (OC) depleted in 13 C is a widely used tracer for terrestrial organic matter (OM) in aquatic systems. Photochemical reactions can, however, change δ 13 C of dissolved organic carbon (DOC) when chromophoric, aromatic-rich terrestrial OC is selectively mineralized. We assessed the robustness of the δ 13 C signature of DOC ( δ 13 C DOC ) as a tracer for terrestrial OM by estimating its change during the photobleaching of chromophoric DOM (CDOM) from 10 large rivers. These rivers cumulatively account for approximately one-third of the world's freshwater discharge to the global ocean. Photobleaching of CDOM by simulated solar radiation was associated with the photochemical mineralization of 16 to 43% of the DOC and, by preferentially removing compounds depleted in 13 C, caused a 1 to 2.9‰ enrichment in δ 13 C in the residual DOC. Such solar-radiation-induced photochemical isotopic shift could bias the calculations of terrestrial OM discharge in coastal oceans towards the marine end-member. Shifts in terrestrial δ 13 C DOC should be taken into account when constraining the terrestrial end-member in global calculation of terrestrially derived DOM in the world ocean.
Subaru weak lensing measurement of a z = 0.81 cluster discovered by the Atacama Cosmology Telescope Survey

We present a Subaru weak lensing measurement of ACT-CL J0022.2 0036, one of the most luminous, high-redshift (z = 0.81) Sunyaev-Zel’dovich (SZ) clusters discovered in the 268 deg 2 equatorial region survey of the Atacama Cosmology Telescope that overlaps with SDSS Stripe 82 field. Ours is the first weak lensing study with Subar u at such high redshifts. For the weak lensing analysis using i ′ -band images, we use a model-fitting (Gauss-Laguerre shapel et) method to measure shapes of galaxy images, where we fit galaxy images in different exposures simultaneously to obtain best-fit ellipticities ta king into account the different PSFs in each exposure. We also take into account the astrometric distortion effect on galaxy images by performing the model fitting in the world coordinate s ystem. To select background galaxies behind the cluster at z = 0.81, we use photometric redshift (photo-z) estimates �
The Relationship between Placement of Female Teachers and Academic Performnace of Secondary School Students in Owerri Urban of Imo State

This research focused on the relationship between placement of Women Teachers and Academic Performance of Secondary School Students in Owerri Urban of Imo State. Descriptive research design was adopted in carrying out the study. A random sampling technique was used to select ten (10) secondary schools used in the study out of twenty secondary schools in Owerri Urban of Imo state. Questionnaire was developed to collect primary data. The data collected was analyzed using the simple percentage method. It ascertained whether there are more female teachers in the Owerri Urban Secondary Schools than their male counterparts thereby assessing the role of women teachers to the education of the students, vis-a-vis their academic performance. In pursuance of the objectives, some hypotheses were stated as seen in chapter 1. A total of twelve schools (12) were sampled with twenty five (25) principals and vice principals, some classroom teachers and officials of the Secondary Education Management Board Owerri Zone as respondents. Data was collected through the use of questionnaires, oral interviews and personal observations respectively. From the findings as reflected in chapter five (5), it was concluded that although many variables are contributory to the excellent and poor performance of students, the posting of many women teachers in a School lowers teachers/school productivity and consequently affects adversely the student’s academic performance. In order to improve the standard of education and this development in particular, some recommendations were made among which among them was government review of the policy of posting married women teachers within the areas their husbands are working to avoid over-concentration of women teachers in the urban Secondary Schools. Keywords: Student, Perception, School, Teacher, Female Teacher, Leadership, Behaviour, Leadership Behaviour.
How to become a superhero

We analyze a collaboration network based on the Marvel Universe comic books. First, we consider the system as a binary network, where two characters are connected if they appear in the same publication. The analysis of degree correlations reveals that, in contrast to most real social networks, the Marvel Universe presents a disassortative mixing on the degree. Then, we use a weight measure to study the system as a weighted network. This allows us to find and characterize well defined communities. Through the analysis of the community structure and the clustering as a function of the degree we show that the network presents a hierarchical structure. Finally, we comment on possible mechanisms responsible for the particular motifs observed.
Almost periodic measures and Bragg diffraction

In this paper we prove that the cone PDS(G)? > of positive, positive definite, discrete and strong almost periodic measures over a σ-compact, locally compact Abelian group G has an interesting property: given any positive and positive definite measure μ smaller than some measure in PDS(G)? >, the strong almost periodic part μS of μ is also in PDS(G)? >. We then use this result to prove that given a positive-weighted Dirac comb ω with finite local complexity and pure point diffraction, any positive Dirac comb less than ω has either a trivial Bragg spectrum or a relatively dense set of Bragg peaks.
The qualiTy and subjecTive confidence of wiTness TesTimony : a comparison of The enhanced cogniTive inTerview and The sTrucTured inTerview

A video clip depicting a burglary was shown to eighty-seven participants. The following day they completed either an enhanced cognitive interview (EcI; n = 43) or a structured interview (sI; n = 44). The participants in the EcI group reported more correct details than those in the sI group (43.12 compared to 32.39) and slightly more incorrect details (1.53 compared to 0.80). no significant differences were observed for the confabulated details. The number of both correct (41.58 compared to 31.59) and incorrect (8.28 compared to 6.07) details of which the participants were confident was higher in the EcI than in the sI group. no differences emerged where the number of details of which the participants were unconfident was concerned. In the structured interview group, the men produced more confabulated details than the women (5.29 compared to 2.56). no other gender differences were observed in either group. The interviewers differed in the quality of testimony obtained in the sI, but not in the EcI.
The functional properties, pasting and baking behaviour of chemically modified sour cassava starches

Starches obtained from three varieties of cassava (Manihot palmata Muell), (4(2)1425 (V1), NR84104 (V2) and NR84293 (V3)) were fermented and chemically modified. The functional and pasting properties of the starches were investigated and the possible contributions of these properties to the explanations of the baking potentials of the starches. The hydrophilic nature of the starches was found to improve strongly after fermentation, while the hydrophobic tendency decreased. The fermented acetylated starches gave the highest value for the swelling index (SWI) and these values were significantly different (p ≤ 0.05) (with the exception of the acid-thinned starches). The pasting temperature for all the starches ranged from 71.9 to 77.6°C and the pasting time was higher in the fermented starches. The peak viscosity (PV) ranged from 151.58 to 317.75 RVU in V1, 154.08 to 249 RVU in V2 and 86 to 243.75 in V3. With the exception of unfermented acetylated starches (AcUFCS) all the modifications reduced the PV of the native starch. AcUFCS had the highest PV (317.75 RVU). Although, the different modification showed different effect on the sensory properties of the wheat/starch bread, highest score for the overall acceptability was associated with the unfermented acetylated starches. Key words: Cassava, fermentation, modification, viscosity, specific volume.
Uptake and distribution of lead in tobacco ( Nicotiana tabacum L.)

Six Nicotiana tabacum varieties were in vitro cultured and experimentally exposed to lead in order to estimate lead uptake and distribution in tobacco plantlets and to observe possible differences depending on variety. Fifty-day-old plantlets were exposed to four Pb rates ranging from 0 to 200 mg dm -3 . No statistically significant effect of lead on dry matter weight was observed for any variety or plant part. Tissue lead concentration was determined on upper leaves, lower leaves, stems and roots. Lead accumulation in the plant positively correlated with lead exposure level. Lead concentration in the different plant parts decreased as follows: root, lower leaves, stem and upper leaves. All tobacco varieties showed similar behaviour with respect to lead treatment level and revealed the same distribution pattern of lead concentration in the different plant part. The highest values of tissue lead concentration were found in tobacco variety Pr61, while the lowest in G94-2.
Modelling of Ballistic Impact over a Ceramic-Metal Protection System

The behavior of ceramic-metal protection against a projectile impact is modeled. The model takes into account the mass and velocity for each stage of the phenomenon. A former model was modified considering more realistic parameters such as geometries and deformation profile. To analyze the model, simulations on different parameters have been run. The impact results of different ballistic projectiles were simulated, and the movement was plotted. In addition, a deterministic simulation on the mechanical properties of the back metal plate properties was done.
Predicting the neutral hydrogen content of galaxies from optical data using machine learning

We develop a machine learning-based framework to predict the HI content of galaxies using more straightforwardly observable quantities such as optical photometry and environmental parameters. We train the algorithm on z=0-2 outputs from the Mufasa cosmological hydrodynamic simulation, which includes star formation, feedback, and a heuristic model to quench massive galaxies that yields a reasonable match to a range of survey data including HI. We employ a variety of machine learning methods (regressors), and quantify their performance using the root mean square error ({\sc rmse}) and the Pearson correlation coefficient (r). Considering SDSS photometry, 3$^{rd}$ nearest neighbor environment and line of sight peculiar velocities as features, we obtain r $> 0.8$ accuracy of the HI-richness prediction, corresponding to {\sc rmse}$ 0.9$ at $z=0$, followed by a Deep Neural Network with r $>0.85$. All regressors exhibit a declining performance with increasing redshift, which limits the utility of this approach to $z\la 1$, and they tend to somewhat over-predict the HI content of low-HI galaxies which might be due to Eddington bias in the training sample. We test our approach on the RESOLVE survey data. Training on a subset of RESOLVE data, we find that our machine learning method can reasonably well predict the HI-richness of the remaining RESOLVE data, with {\sc rmse}$\sim0.28$. When we train on mock data from Mufasa and test on RESOLVE, this increases to {\sc rmse}$\sim0.45$. Our method will be useful for making galaxy-by-galaxy survey predictions and incompleteness corrections for upcoming HI 21cm surveys such as the LADUMA and MIGHTEE surveys on MeerKAT, over regions where photometry is already available.
Properties of foamed concrete reinforced with hybrid fibres

The properties of foamed concrete reinforced with carbon fibres and hybrid fibres of carbon with polypropylene fibres has been studied. Various volumetric fractions of carbon fibres (0.5, 1 and 1.5%), hybrid fibres of carbon fibres (CF) with polypropylene fibres (PPF) as (1% CF + 0.5% PPF) & (0.5% CF + 1% PPF), also the mono polypropylene fibres as 1.5% PPF were used to reinforce foamed concrete mix. Fresh and hardened properties of all mixes included flowability, density, absorption, compressive strength, splitting tensile strength, and flexural strengths has been tested. Results showed that inclusion of carbon fibres up to 1% volumetric fraction may increase the compressive strength by about 36% higher than that of control mix. Whereas, the use of 1.5% carbon fibres exhibit significant increase in splitting and flexural tensile strengths by about 47 and 114%, respectively, compared to the reference mix. On the other hand, the hybridization of 1% CF + 0.5% PPF increased the splitting tensile strength and flexural strengths by 53% and 114%, respectively, compared with plain foamed concrete mix.
