Dimensionality Control in Crystalline Zinc(II) and Silver(I) Complexes with Ditopic Benzothiadiazole-Dipyridine Ligands

Three 2,1,3-benzothiadiazole-based ligands decorated with two pyridyl groups, 4,7-di(2-pyridyl)-2,1,3-benzothiadiazol (2-PyBTD), 4,7-di(3-pyridyl)-2,1,3-benzothiadiazol (3-PyBTD) and 4,7-di(4-pyridyl)-2,1,3 benzothiadiazol (4-PyBTD), generate ZnII and AgI complexes with a rich structural variety: [Zn(hfac)2(2-PyBTD)] 1, [Zn2(hfac)4(2-PyBTD)] 2, [Ag(CF3SO3)(2-PyBTD)]23, [Ag(2-PyBTD)]2(SbF6)24, [Ag2(NO3)2(2-PyBTD)(CH3CN)] 5, [Zn(hfac)2(3-PyBTD)] 6, [Zn(hfac)2(4-PyBTD)] 7, [ZnCl2(4-PyBTD)2] 8 and [ZnCl2(4-PyBTD)] 9 (hfac = hexafluoroacetylacetonato). The nature of the resulting complexes (discrete species or coordination polymers) is influenced by the relative position of the pyridyl nitrogen atoms, the nature of the starting metal precursors, as well as by the synthetic conditions. Compounds 1 and 8 are mononuclear and 2, 3 and 4 are binuclear species. Compounds 6, 7 and 9 are 1D coordination polymers, while compound 5 is a 2D coordination polymer, the metal ions being bridged by 2-PyBTD and nitrato ligands. The solid-state architectures are sustained by intermolecular π–π stacking interactions established between the pyridyl group and the benzene ring from the benzothiadiazol moiety. Compounds 1, 2, 7–9 show luminescence in the visible range. Density Functional Theory (DFT) and Time Dependent Density Functional Theory (TD-DFT) calculations have been performed on the ZnII complexes 1 and 2 in order to disclose the nature of the electronic transitions and to have an insight on the modulation of the photophysical properties upon complexation.
Theorising an organisational citizenship behaviour model for managerial decision-making: from history to contemporary application

Purpose This study aims to expand the theory of organisational citizenship behaviour (OCB) to include “exterior” behaviours. By advancing the work of Blake and Mouton (1964) and remapping the performance/OCB dimensions offered in the historical literature, a new holistic model of organisational performance is proposed. As a further step, a decision-making tool is proposed for managerial decision-making and to help predict employee performance. Design/methodology/approach The paper adopts a critical review and conceptual approach to explore historical OCB theories and task performance (TP) taxonomies. It then used Blake and Mouton’s managerial grid to construct a contemporary conceptual tool for managerial decision-making. Findings Despite the performance literature not lacking in quantity, a few of such research have led to a pragmatic managerial tool. The review reveals several confusions regarding the accurate classification of what actually constitutes OCB and what constitutes TP – this gap is filled by the introduction of the OCB model for managerial decision-making (OMMD). Research limitations/implications The current work expands our thinking on OCBs that can occur outside the organisation. These exterior behaviours can influence the organisation’s performance and must be managed just like any other performance metric. The OMMD, primarily based on OCB and TP, provides an initial framework for exploring different typologies of employees. Despite being based on several cogent performance literatures, the proposals have not been tested empirically. Practical implications Like the Blake and Mouton model, the new OMMD can be useful in estimating the proportions of employee OCBs and TP. Social implications Culture and social exchange theory can be seen as playing a role in separating TP from OCB. Originality/value This study extends the work of Bateman and Organ (1983) by suggesting that some work behaviours can occur outside the organisation. Besides, a decision-making proposal is offered based on the managerial grid framework (Blake and Mouton, 1964).
The Implementation of Using Whatsapp and Youtube in FLTM Class: Teacher’s Perception

The objective of this study is to find out the teacher’s perception on the implementation of using Whatsapp messanger and Youtube in class B 5th semesters of FLTM classroom at Muhammadiyah University students of Kendari. Since teacher’s perception has not been investigated thoroughly in the earlier research on the implementation of using WhatsApp and Youtube media as a learning tools. This study employs qualitative study design to find out lecturer’s perception in teaching process using Whatsapp and Youtube. The instruments used in this study are documentation and interview and the data are analyzed using data reduction, data display, meaning coding, meaning condensation, meaning interpretation, conclusion drawing and data triangulation. The findings reveal that the teacher considered to implement Whatsapp and Youtube in teaching have several advantages and disadvantages in learning objective and outcomes. This can be viewed in the arrangement of knowledge of subject matter, teacher-students interaction, design of instruction, and course management. Furthermore, teacher’s beliefs in using Whatsapp and Youtube in teaching appeared to be strongly connected to the flexibility of teaching and learning process and learning content availability.
Sustainable Aging and Leisure Behaviors: Do Leisure Activities Matter in Aging Well?

A substantial portion of the gerontological literature has been directed towards the relationship between leisure and aging, particularly with the healthy life of older adults. The concept of leisure conveys varied meanings to persons, including identifying the leisure itself, the activity’s frequency, and its value to the participant. With increased longevity, the concept of aging well and related terms (e.g., “active aging”, “successful aging”, “productive aging”, “positive aging”, “healthy aging”, and “sustainable aging”) have been emerging themes for academic fields related to gerontology, exercise promotion, health care, and leisure activities. Thus, the aging population and human leisure activities must be considered sustainable as sustainability is primarily human-centered. This study explores older adults’ perceptions of leisure and aging well and their leisure behavior at senior welfare centers using qualitative data collection and methodology. Findings suggest that four main themes emerge: unfamiliarity with the concept of leisure and leisure engagement; evolving perceptions of senior centers and leisure benefits; limited physical functioning as a major leisure constraint; perceptions of major factors for aging well. Implications for researchers and policymakers are discussed.

 Polygonum aviculare
 control in
 Cynodon dactylon
 turf

Peer-reviewed research is not available to explain Polygonum aviculare L. (prostrate knotweed) control in Cynodon dactylon (bermudagrass) turf, yet P. aviculare is common and troublesome in managed C . dactylon turf. Six experiments were conducted to determine control options for P. aviculare in C. dactylon golf roughs managed in Hanover, VA. Studies evaluated hormone, photosystem, and ALS inhibiting herbicides. Among a group of eighteen herbicide treatments, only six controlled P. aviculare over 80% and these included single products or mixtures containing 2,4-D, dicamba, metsulfuron, or chlorsulfuron. Imazaquin, quinclorac, and triclopyr caused transient C. dactylon injury. Treatments dependent on bromoxynil, triclopyr, clopyralid, quinclorac, metribuzin, rimsulfuron, imazaquin, foramsulfuron, flazasulfuron, trifloxysulfuron sodium, or sulfosulfuron are unlikely to adequately control P. aviculare in C. dactylon turf.
Validation of Family Functioning Questionnaire (FFQ) with a Sample of Parents of Children with Autism Spectrum Disorder in Addis Ababa

Contextually validated measures of family functioning of parents with special needs are unavailable in Ethiopia. This study was aimed to validate the Amharic version of the Family Functioning Questionnaire (FFQ) with evidence from community samples of families of children with Autism Spectrum Disorder (n=72). Having translated the FFQ into Amharic, then the validation processes of assessing the psychometric properties (validity and reliability) of the instrument were conducted using experts’ judgments, factor analysis, and internal consistency measures. The face and content validity assessments resulted in a measure that lends itself to the construct it intends to measure. The principal component factor analysis brought out two factors ( problem-solving and personal goal) with the majority of items demonstrated a factor loading above 0.5. The convergent validity of the FFQ was demonstrated via the Dyadic Adjustment Scale in which the observed significant intercorrelations suggested a strong construct validity of the Amharic FFQ. The internal consistency of the scale was also good, with a Cronbach’s alpha of 0.82 for the whole scale and 0.91 and 0.82 for the problem-solving and personal goal sub-scales respectively. Hence, the Amharic version of the FFQ can be used for measuring the quality of family functioning in families of children with developmental disorders in the Ethiopian context.
Polarization induced three-dimensional hole gas in compositionally graded InxGa1−xN layer

A polarization-induced three-dimensional hole gas (3DHG) was demonstrated in undoped and compositionally graded InxGa1−xN layers. All samples were grown on Ga-face bulk GaN substrates by metal organic chemical vapor deposition. A high hole concentration of 2.8 × 1018 cm−3 was obtained in a 100-nm-thick InxGa1−xN layer where the indium composition was graded from x = 0 to x = 0.2. 3DHG density control by varying the indium composition and thickness of a compositionally graded InxGa1−xN layer was also demonstrated.
The Relationship between Body Mass Index and Incident Diabetes Mellitus in Chinese Aged Population: A Cohort Study

Objectives Previous studies reported that overweight older adults had a lower mortality after cardiovascular diseases attack, indicating being thinner might not always be better. However, there is an ongoing debate about what is the optimal range of body mass index (BMI) for the aged population. We aimed to evaluate the value of BMI for the prediction of incident diabetes mellitus (DM) in the Chinese elderly population. Methods A total number of 6,911 Chinese elderly people (4,110 men and 2,801 women, aged 71 ± 6.0 years) were included in this cohort study. BMI was measured at baseline (Jan 1, 2014, to Dec 31, 2014). All the participants were further classified into six groups: <18.5 kg/m2, 18.5 to <22.5 kg/m2, 22.5 to <25.0 kg/m2, 25.0 to <27.5 kg/m2, 27.5 to <30.0 kg/m2, and ≥30.0 kg/m2. Fasting blood glucose (FBG) and glycated hemoglobin A1c (HbA1c) were annually measured during follow-up (Jan 1, 2015-May 31, 2019). DM was confirmed if either FBG ≥ 7.0 mmol/L or HbA1c ≥ 6.5%. We used the Cox proportional hazard regression model to evaluate the association between BMI and the prediction of incident DM. Results Comparing individuals with a BMI range of 18.5 to <22.5 kg/m2 (reference), the hazard ratio for incident DM was 2.13 (95% CI: 1.54~2.95), 2.14 (95% CI: 1.53~3.00), 3.17 (95% CI: 2.19~4.59), 3.15 (95% CI: 1.94~5.09), and 3.14 (95% CI: 1.94~5.09) for the group with a BMI range of 22.5 to <25.0 kg/m2, 25.0 to <27.5 kg/m2, 27.5 to <30.0 kg/m2, and ≥30.0 kg/m2 after adjusting for baseline age, sex, blood pressure, lipid profiles, and eGFR (P trend < 0.001), after adjusting for the abovementioned confounders. The association tended to be closer in men and young participants, compared with their counterparts. Conclusions High BMI was associated with a high risk of developing DM in the Chinese aged population. Thus, it is optimal for the aged population to maintain their body weight within a reasonable range to prevent chronic diseases.
Effect of epidural labor analgesia on postpartum depression and maternal and infant outcomes in parturients with gestational diabetes mellitus---A prospective cohort study

BackgroundPostpartum depression (PPD) negatively affects the health of new mothers and can impair infant development. Both labor pain and gestational diabetes mellitus (GDM) are potential risk factors for PPD. However, the effects of epidural labor analgesia in parturients with GDM on PPD and maternal and infant outcomes have not been characterized.MethodsParturients with GDM in our hospital were assigned to the epidural group (n = 133) and no epidural (control) group (n = 130) according to their choice to receive epidural labor analgesia. The Edinburgh Postnatal Depression Scale (EPDS) was used to evaluate maternal mental status at 24 h and 42 days postpartum. Data for relative variables in the perinatal period were collected, and the potential associations of epidural analgesia with PPD and maternal and infant outcomes were analyzed by univariate analysis and multivariate logistic regression analyses.ResultsEpidural analgesia was a protective factor for PPD at 24 h postpartum (odds ratio [OR], 0.301, 95% confidence interval [CI]: 0.104–0.867, p < 0.05), and the EPDS score at 24 h post-delivery showed significant correlation with that at 42 days post-delivery (Pearson correlation coefficient = 0.527, p < 0.001). The rate of neonatal admission to the neonatal intensive care unit (NICU) for hypoglycemia was higher in the epidural group (6.92%) than in the control group (1.50%; p < 0.05). Epidural analgesia and drug-based diabetes control were independent predictors of the rate of neonate transfer to the NICU for hypoglycemia.ConclusionEpidural analgesia was a protective factor for PPD at 24 h postpartum, but associated with an increased risk of neonatal transfer to the NICU for hypoglycemia. Thus, monitoring of neonatal blood glucose levels after administration of epidural analgesia in parturients with GDM may be beneficial.Clinical Trial Registrationthe study was registered in the China Clinical Registration Center (URL: http://www.chictr.org.cn/listbycreater.aspx, Registration No. ChiCTR-OOC-17013164)
A high performance soy protein-based bio-adhesive enhanced with a melamine/epichlorohydrin prepolymer and its application on plywood

The aim of this study was to improve the water resistance of a soy protein-based bio-adhesive using a melamine/epichlorohydrin prepolymer (MEP). The multi-epoxy groups in the MEP reacted with active groups on the protein molecule and formed a crosslinked and denser network, which improved the water resistance of the resulting adhesive. In addition, the addition of a MEP increased the thermal ability of the cured adhesive and created a smooth surface with fewer holes and cracks preventing moisture intrusion and further improving the water resistance of the resulting adhesive. Furthermore, the use of MEP introduced a rigid structure into the adhesive formulation, which increased the rigidity of the cured adhesive, and further increased the water resistance of the adhesive. Incorporating 6 wt% MEP effectively improved the water resistance of the adhesive by 10.5%. The wet shear strength of the plywood bonded with the resultant adhesive increased by 281.1% to a maximum value of 1.41 MPa, which was higher than that of the soy beanmeal/PAE adhesive and commercial MUF and UF resin. This improvement in the resultant plywood was attributed to the adhesive water resistance improvement and additional interlock formation between the wood and adhesive resulting from the higher solid content of the adhesive as well as the viscosity reduction. The resultant adhesive has a solid content of 32.65% and viscosity of 499, 400 mPa s, which is acceptable for the industrial application of plywood fabrication.
Train-the-Trainers Biology Workshop as an Effective Science Advocacy Tool: An Impact Assessment and Emerging Issues for Science Education

Science advocacy is an important tool for ensuring improved and more beneficial science education, especially in resource-poor countries. This study assessed the impact of a train-the-trainer biology workshop (TTTBW) as a useful instrument for science advocacy and maximizing biology teacher training. Thirty-one biology teachers (30% male and 70% female) participated in the two-day TTTBW, competitively selected from 25 secondary schools in urban areas of Anambra State, Nigeria where they were taught several pre-identified need-based topics as part of professional development. Some of the topics taught include: A) Effective communication skills for biology teaching B) Teaching management skills C) Dynamics of child education D) New pedagogical skills in teaching Biology E) Strategies for targeted Assessment in Biology F) Adaptation of Biology teaching for resource-poor countries. Each of the topics lasted for at least an hour and a pre and post-test was done for topics A-C and analyzed. Pre-workshop assessment and post-workshop impact assessment interviews were also carried out through an online form and self-administered questionnaire respectively. There was a significant increase in the post-test scores of the teachers in topics examined (A-C) when compared to the pre-test scores (p= 0.00, 0.00, and 0.004 respectively). After the workshop, the interest to teach biology was increased in most of the participants (91%) compared to 23% before the workshop. TTTBW is a potent tool for science advocacy and professional development for teachers and exhibits scale-up potentials for maximal impact.
Potential Use of Renewable Energy for Rural Electrification in Pakistan by Incorporating Blockchain Technology

Background: Significant innovations in technology and progressing use of renewable energy sources (RES) reinforce the demand for the sustainable, continuous and abundant supply of energy to every consumer. Blockchain, as an emerging technology promises to provide temper proof, secure, transparent and decentralized energy trading mechanisms that help to provide sustainable environmental solutions by circulating economy to empower both consumers and prosumers. The rapid development of blockchain technology has gained interest from energy start-ups, innovation developers, finance suppliers, academic institutions and government. Results: This study outlines potential significance, benefits and application of blockchain technology and analyses how Pakistan can integrate blockchain technology into its distribution system to cope with current challenges. Although the substantial renewable potential of Pakistan is an opportunity to implement blockchain technology but financial management, innovative technology development and acceptance of decentralized technology are the biggest obstacles. After a detailed discussion of Pakistan's current financial position, digital market structure, energy policy and technology situation for the implication of blockchain technology, Photographic Geographical Information System (PVGIS-5) data base tool is used to estimate solar power generation capacity from prosumer community in potential areas of country like Baluchistan. Conclusion: This study recommended feasible site for solar power generation according to PVGIS tool. Then introduces a street scenario about domestic power generation and blockchain based distribution into Pakistan's energy sector like Brooklyn energy system by regulating laws, revising energy polices and suitable development subsidies.
Evaluating barriers and solutions for social sustainability adoption in multi-tier supply chains

ABSTRACT Multi-tier sustainable supply chain management (MT-SSCM) is increasingly attracting a great deal of interest in academia and practice. However, attention to social sustainability has been relatively limited, and the initiatives of implementing social sustainability, especially in low-tier suppliers in supply chains, are facing enormous barriers and obstacles. The central aim of this paper is to investigate the obstacles that hinder the adoption of social sustainability in the multi-tier supply chain (MT-SC) and prioritise the most effective solutions to promote the adoption of this critical concept. Therefore, we based an extensive literature review on identifying the most relevant barriers and solutions to social sustainability adoption in MT-SC. Moreover, we propose a hybrid and multi-context methodology based on hesitant fuzzy sets (HFS), cumulative prospect theory (CPT) along with VIKOR to identify the most prominent barriers and solutions for three supply-chain sectors, i.e. chemical, agri-food, and textile. The results indicate that solutions to social sustainability in MT-SC are sensitive to the supply chain sector. However, there is a general trend toward adopting emerging technologies and openness and transparency-based relationships with the external environment. Managers could use these results to redirect their strategies to promote social sustainability, particularly in low-tier suppliers in under-developed countries.
Permanent Co‐Seismic Deformation of the 2013 Mw7.7 Baluchistan, Pakistan Earthquake From High‐Resolution Surface Strain Analysis

Repeated earthquake cycles produce topography, fault damage zones, and other geologic structures along faults. These geomorphic and structural features indicate the presence of co‐seismic permanent (inelastic) surface deformation, yet a long‐standing question in earthquake research is how much of the co‐seismic deformation field is elastic versus inelastic. These questions arise in part because it is unclear what measurable co‐seismic characteristics, such as off‐fault or distributed surface deformation and cracking, represent true unrecoverable deformation. One emerging descriptor of permanent co‐seismic deformation is surface strain magnitudes inferred from imaging geodesy observations. In this study, we present the surface strain field of the 2013 Mw7.7 Baluchistan strike‐slip earthquake in southern Pakistan. We invert co‐seismic displacement fields generated from pixel‐tracking of SPOT‐5 and WorldView optical imagery for co‐seismic surface horizontal strain tensors. We observe that co‐seismic strain field is dominated by negative dilatation strains, indicating that the co‐seismic fault zone contracted during the earthquake. We show that co‐seismic inelastic failure exhibits a relatively consistent width along the rupture that is localized to a zone 100–200 m wide on the hanging wall side. The width of co‐seismic permanent deformation does not correlate with variations in off‐fault deformation or surface geology. Based on comparisons to other recent earthquakes, we posit that the permanent surface strains reflect inelastic deformation of the faults inner damage zone, and that the width of this zone reflects fault maturity.
