The role of job satisfaction as mediator between work-life balance and organizational commitment among lecturers

Lecturer profession is regarded as high-pressured in which lecturers find it difficult to divert their attention from working life to personal life outside working hours. This balance of personal-work life is found to influence employee attitudes, perceptions, and performance. The aim of this study is to find the effect of the work-life balance on lecturers’ organizational commitment with job satisfaction as a mediator. The subjects in this study were 110 permanent lecturers from five universities in Padang City, Indonesia, who were selected based on purposive sampling and required to complete a questionnaire consisting of Work-life Balance Scale, Job Satisfaction Survey, and Organizational Commitment Scale. A simple mediation analysis was conducted using PROCESS macro. The results show that there was a positive significant effect of work-life balance on job satisfaction, job satisfaction on organizational commitment, and work-life balance on organizational commitment. In addition, job satisfaction was found as a partial mediator in the relationship between work-life balance and organizational commitment. This study provides important implications for higher education institutions to consider the work-life balance among lecturers to improve their job satisfaction and organizational commitment.
19. A Sociological View on Hierarchical Failure: The Effect of Organizational Rules on Exchange Performance in Buyer- Supplier Transactions

The classic Transaction Cost Economics view is that a key reason for firms to exist is that they offer a way to overcome problematic market transactions. If it is too complicated, expensive, or risky to buy a good on the market, consider hiring employees to make it in-house - especially if it is a good that you (and others) might need often. The implicit argument is that, for this reason, firms are a potentially rational response to less advantageous markets. However, firms are rational responses only when they themselves are organized in a way that is efficient enough to outperform the market. We consider firms’ hierarchical efficiency by analyzing the existence and consequences of rules and procedures, effectively testing two competing arguments. On the one hand, rules and procedures are one way in which firms can achieve efficiency, through specialization and formalization of what a firm has learned. On the other hand, rules can be imprecise and rigid, a nuisance to deal with, and just coincidental traces of what has gone wrong in the past. Using a database of more than 800 transactions in which German small and medium sized businesses buy ICT products and services, we consider the role of rules and procedures in a large-scale quantitative way. It turns out that rules show a pyramid-like structure where some firms have less and others have more codified rules. Our results furthermore suggest that rules might not be the clotted efficiency they have been argued to be. A high rule-density goes with increased investments in contracting (“thicker contracts”) and not with decreased ex post transaction problems, questioning the benefits of rules as a way to favor firms over markets.
Genetic Considerations for Selecting the Seedlings to Restore a Small Population of Abies koreana, an Endangered Fir Species that is Endemic to Korea

Korean fir (Abies koreana E.H. Wilson), which is a Korean endemic species that has been designated as an endangered species by the International Union for Conservation of Nature, has been declining by approximately 33% in its natural habitat. There are three large and six small populations with a relatively large and small number of individuals, respectively. The Korean fir population in Mt. Geumwonsan is known to have only 20 adult trees and approximately 23 seedlings. It was also observed that the seed production was extremely poor, while the genetic diversity (He=0.612) is lower than that of other large populations in Korea, with a very high fixation index of the seedlings (F=0.318). Therefore, there is a high risk of local extinction due to the inbreeding effect with the limited number of trees and a great need to implement restoration projects immediately to reduce the risk. Selecting the restoration materials for the small population needs to consider the genetic diversity and uniqueness of the natural population while enhancing their adaptability and resilience against environmental change. Hence, to restock the Korean firs into the Geumwonsan population, we evaluated the genetic similarity between the populations in Korea and suggested a guideline to select the appropriate materials for restoration.
Coauthor Network Analysis of Journal of Agricultural Education Articles from 2008-2017

The social capital of collaboration is a critical part of the research process. While AAAE supports collaboration and inclusivity, analysis has not occurred for what collaborations are occurring. This study addressed collaboration between researchers via a social network analysis of coauthorship in the Journal of Agricultural Education from 2008 to 2017. There were 587 articles published in that time frame with 593 unique authors. The number of articles published annually and number of authors per article increased during the 10-year period. The majority of authors only published one article in the time frame analyzed. After excluding authors who never collaborated on an article, a social network of 582 coauthors was analyzed. There was a general tendency for the most prolific authors to also be the most connected, though there were some outliers. Of note, the majority of the most connected authors received their terminal degrees from one of three institutions. The majority of the most prolific coauthor pairs were advisor-advisee pairings, and the remainder were individuals who had worked at the same institution during much of the study’s time frame. A prolific coauthor pairing was not necessarily indicative of a connection that was important for bridging authors across the network.
ANTIBACTERIAL ACTIVITIES OF THE SEED EXTRACTS OF SOME INDIGENOUS PLANTS

The chloroform and methanol extracts of seed and seed coat of Caesalpinia bonduc L. , Mucuna pruriens L. , Adenanthera pavonina L. , Terminalia bellirica Geatn. , Syzygium cumini L. and Myristica fragrans Houtt. were tested against 14 pathogenic bacteria. According to the intensity of activity against the selected bacteria the extracts could be arranged in a descending order of M. fragrans > A. pavonina > S. cumini > C. bonduc > M. pruriens > T. dbelerica. The minimum inhibitory concentrations (MIC) of the chloroform extract of seed of Syzygium cumini were 128 μg/ml against Bacillus cereus and 64 μg/ml against S. aureus. For the methanol extract the MIC values were 128 μg/ml against B. cereus, Shigella dysenteriae and 64 μg/ml against B. megaterium, S. aureus and S. sonnei.

In contrast, with diazoalkanes 1,3-dipolar cycloaddition takes place to yield the not yet described mesoionic and non-mesoionic 5-methylene-1,2,3-thiadiazoles 10 and 9, resp. , in one operation.
Low-Profile Broadband Magnetoelectric Dipole Antenna With Dual-Complementary Source

In this letter, a magnetoelectric (ME) dipole antenna with low profile, broadband, stable unidirectional radiation is presented. Traditional Γ-shaped feeding structure is shunted, improved, and hence a dual-magnetic dipole is formed. Furthermore, a dual-electric dipole is also formed by etching a slot on top electric dipole patch. Therefore, an ME dipole antenna with a dual-complementary source is achieved by combining both of dual-magnetic dipole and dual-electric dipole element and has a very lower profile of 0. 079λ0 (λ0 is the free-space wavelength of center frequency). Additionally, the working principle is analyzed by discussing the surface current of this dual-complementary source ME dipole. The electric dipole and magnetic dipole work alternatively in one period of time domain. By measurement, the relative impedance bandwidth is 46.2% (from 2.45 to 3.92 GHz) for VSWR<2. Boresight gain ranges from 6.98 to 10.19 dBi in its impedance bandwidth. A low crossed polarization is also obtained. By comparison with other works, the proposed antenna has an advantage in broadband and height-saved applications.
Rice husk as bio-source of silica: preparation and characterization of PLA–silica bio-composites

Silica powder has been extracted from rice husk employing a simple extraction procedure for preparing poly(lactic acid) bio-composites with differing filler contents (namely, 5, 10, 20 and 30 wt%). These materials have been obtained through a semi-industrial process of extrusion. The thermal, mechanical and morphological properties have been investigated. Despite a broad distribution of silica particle size, the prepared bio-composites have exhibited improved storage modulus and reduced oxygen permeabilities. The collected values at 10 and 30 wt% have been compared with those of homologous samples prepared using a commercial silica. Two micro-mechanical models (Voigt and Halpin–Tsai) have been used to also fit the mechanical data. Finally, an economic analysis of material and energetic costs has been performed on samples containing silica from rice husk in order to establish if the proposed process is sustainable or advantageous.
Antiferroelectric modulations in Sb2WO6 and Sb2MoO6

The structure of Sb 2 WO 6 [M r = 523.4, triclinic, F1, a = 11.132(1), b = 9.896 (4), c = 18.482(7) A, α = 90.20 (4), β = 96.87(8), γ = 90.21(5)°, D x = 6.88 g cm -3 , Z = 16, Mo Kα, λ = 0.7107 A, μ = 338.5 cm -1 , F(000) = 3536] has been refined as an enlarged 2a x 2b x 2c F-centred superstructure of the previously reported structure [Castro, Millan, Enjalbert, Snoeck & Galy (1994). Mat. Res. Bull. 29, 871-879] refined in the space group P1. The re-refinement follows the observation, initially by TEM, of satellite reflections at G ± 1/2 (111)*, where G represents a reflection of the P1 reciprocal lattice. A final value of 0.040 for R 1 = Σ h ∥F obs (h)|-|F calc (h)∥/Σ h ∥F obs (h)| was obtained for 3316 merged reflections with [(h) > 3σ[1(h)], compared with R 1 = 0.12 for the previous refinement. The refined structure is described in terms of an antiferroelectric modulation of a P12 1 /a1 underlying parent structure in the original setting. Twinning of the crystal was successfully modelled in the refinement. Synthesis of the previously unknown phase Sb 2 MoO 6 [M r = 435.5, triclinic, F1, a = 10.758(1), b = 9.673(2), c = 17.57(1) A, α = 90.00(5), β = 96.98 (3), γ = 90.05 (2)°, Z = 16, D x = 4.97 g cm -3 ] is also reported, along with evidence for its isostructuralism with Sb 2 WO 6 .
Characterization of Methyl tert-Butyl Ether-Degrading Bacteria from a Gasoline-Contaminated Aquifer

Abstract Molecular microbial community analysis was combined with traditional cultivation strategies to investigate the presence of methyl tert-butyl ether (MTBE)-degrading bacteria in a gasoline-contaminated aquifer (Ronan, MT). A bacterial consortium, RS24, which is capable of complete mineralization of MTBE as a sole carbon and energy source was enriched from soil and aquifer materials taken from the contaminated site. The consortium was capable of degrading MTBE at rates up to 0.66 mg d−1, with corresponding gross biomass yields of 0.25±0.02 mg dry biomass (mg MTBE)−1. Two MTBE-degrading isolates identified as Pseudomonas Ant9 and Rhodococcus koreensis were obtained from the consortium. However, both isolates required the presence of 2-propanol as a cosubstrate for MTBE degradation. Denaturing gradient gel electrophoresis (DGGE) of Poly-merase Chain Reaction (PCR)-amplified 16S rDNA confirmed the presence of both isolates in the initial consortium and indicated their disappearance with transfer and subculturing. MTBE degradation and cell growth by the consortium was stimulated by the presence of spent culture medium, suggesting the production of a growth factor during MTBE degradation. These results indicate the presence of naturally occurring MTBE-degrading bacteria in a contaminated aquifer and suggest the potential for natural attenuation or enhanced aerobic oxidation.
Digital V2 Constant ON-Time Control Buck Converter With Adaptive Voltage Positioning and Automatic Calibration Mechanism

This article presents a digital V2 constant on-time control buck converter with adaptive voltage positioning (AVP) and automatic closed-loop output impedance (Zoc) calibration for advanced system-on-a-chip processors. To ensure that the output voltage deviation remains within the desired range, the system is equipped with AVP. For an optimal AVP design, the system includes a second-order digital inductor current sensor for deriving a constant Zoc within a wide bandwidth. A detailed system-level analysis was performed to design the proposed control architecture. Considering the inevitable variation and aging of power stage components, the system is equipped with an online real-time Zoc calibration mechanism established to ensure the performance of AVP control. A prototype chip was fabricated using a 90-nm complementary metal–oxide–semiconductor (CMOS) process. The digital controller was fully realized using a standard cell library. Under a 0.9-A load transient, the measured output voltage could be adequately constrained within a specified 1.1-V and 110-mV AVP window.
e-Lifestyle Confirmatory of Consumer Generation Z

The development of information technology has changed daily life patterns that tend towards digital. Differences across generations will result in understanding different behaviors and lifestyles, which are a challenge in this research. Lifestyle is needed in determining market segments of consumer behavior. Lifestyle understanding in Generation Z is expected to provide valuable information in various fields of socio-economic life. These findings are expected to provide an overview for marketers targeting the market in this segment. Understanding lifestyles can be an ingredient in developing marketing strategies according to the intended segment, especially Generation Z, which has identified a lifestyle following information technology or digital development. The research aimed to confirm e-lifestyle factors among Generation Z, especially university students, as members of the academic environment's dominant academic community. Specifically, the aim is to identify the pattern of e-lifestyle formation in Generation Z, especially among students and the information or social media used by Generation Z. This type of research is a survey. This research was initiated through empirical field observations. The study population used in this study was university students in Yogyakarta-Indonesia. The sampling technique uses a simple random sampling technique. The data used are primary: the response given by research subjects related to e-lifestyle factors. Data was collected through a survey using a questionnaire. The data analysis technique in this study uses a Confirmatory Factor Analysis (CFA). The results showed that the motives that became the basis of e-lifestyle in the Z generation corresponded to four factors, namely, e-activities, e-interests, e-opinions, and e-values. Information or social media are often used by Generation Z, namely, Instagram, Youtube, Line, Facebook, Twitter, Discard, Pinterest, Spotify, and Telegram. The purpose of using the information or social media is communication, entertainment, consumption or shopping, and community activities.
Development and in-vitro evaluation of a multiparticulate sustained release theophylline formulation

AbstractA multiparticulate sustained release formulation of theophylline was developed and evaluated in-vitro. The formulation comprised spherical pellets of high drug loading, coated with a rate controlling membrane. The pellets were prepared using an extrusion spheronisation method, whilst coating was performed with an aqueous dispersion of ethylcellulose using a fluidized bed coating technique. When ethylcellulose was used alone as the coating polymer, the drug release profile was unsatisfactory, but could be improved by incorporating a coating additive. Several additives were evaluated and methylcellulose of high Viscosity grade was found most satisfactory. The in-vitro theophylline release was relatively linear and pH independent, and could be varied in a predictable manner by manipulating the coat thickness. In addition, when the coated pellets were subjected to additional thermal treatment, the drug release was stable after storage for one year.
Multi-responsive hydrogels based on N-isopropylacrylamide and sodium alginate

Hydrogels consisting of sodium alginate and N-isopropylacrylamide covalently crosslinked with N,N′-methylenebisacrylamide were prepared. The mixed-interpenetrated networks obtained were characterized using elemental analysis, Fourier transform infrared and Raman spectroscopy, swelling measurements and environmental scanning electron microscopy. The thermo- and pH-responsive properties of these hydrogels were evidenced by their swelling behaviour, which depended also on the amount of crosslinking agent and hydrogel composition.

An Incentive-Based Mechanism to Alleviate Active Power Congestion in a Multi-Agent Distribution System

Increasing the integration of distributed energy resources (DERs) inspired by environmental and governmental incentives, beside the introduction of multi-agent structure perspective have led to a paradigm shift of operational conditions in distribution systems. In this context, the traditional concept of fit and forget in the distribution grid management would not be efficient in the modern distribution systems and consequently new mechanisms should be developed in order to enable the distribution system operator (DSO) to efficiently manage the grid congestion caused by peak power output of DERs or load demands requests. In this article, the Stackelberg game concept is employed to develop an incentive-based mechanism that facilitates the contribution of local flexible resources operated by independent agents in the congestion management of distribution grids. Therefore, the proposed bi-level formulation would result in congestion alleviation in the multi-agent system; while the objectives associated with DSO and independent agents are fulfilled. Additionally, the developed framework enables DSO to reconfigure the network to decrease the operational costs associated with the congestion alleviation procedure. Finally, the strong-duality concept is utilized in order to combine the two-level problem into a one-level problem and the obtained model is implemented on IEEE-37 bus test system to investigate its effectiveness in congestion management in the distribution system.
Deep metastable eutectic condensation in Al-Fe-SiO-H2-O2 vapors: Implications for natural Fe-aluminosilicates

Abstract Vapors of Al-Fe-SiO-O2-H2 having two different compositions produced ferroaluminosilica grains as a function of agglomeration and fusion along mixing lines in the Al2O3-FeO-SiO2 system that are defined by the predictable, deep metastable eutectic (DME) compositions of the smallest condensate grains. Disorder of these amorphous grains is higher than in quenched glass of identical composition, which is the very property of dissipative structures (Prigogine 1978, 1979) that are states of organization of matter where disequilibrium becomes a source of order. Iron-oxidation states control ferrosilica condensate compositions. We present the first magnetic measurements showing a high Fe3+ content in condensed ferrosilica grains. The Fe-cordierite grain composition is primarily the result of predictable non-equilibrium condensation, not the bulk gas phase composition. Natural terrestrial and anthropogenic (e.g., smelters, coal fly ash) Fe-cordierite might well be a metastable phase due to kinetically controlled processes. Amorphous Mg,Fe-bearing aluminosilica dust in chondritic interplanetary dust aggregates and (rare) Mg,Fe-aluminosilicates in meteorites might have condensed via similar processes.
Recent evolutions in the LTDP CDF project

In the latest years, CNAF (the national center of the Italian Institute for Nuclear Physics INFN dedicated to Research and Development on Information and Communication Technologies) has been working on the Long Term Data Preservation (LTDP) project for the CDF experiment, active at Fermilab from 1990 to 2011. The main aims of the project are to protect the most relevant part of the CDF RUN-2 data collected between 2001 and 2011 and already stored on tape at CNAF (4 PB), as well as to ensure the availability and the access to the analysis facility to those data over time. Lately, the CDF database, hosting information about CDF datasets such as their structure, file locations and metadata, has been imported from Fermilab to CNAF. Also, the Sequential Access via Metadata (SAM) station data handling tool for CDF data management, that allows to manage data transfers and to retrieve information from the CDF database, has been properly installed and configured at CNAF. This was a fundamental step in the perspective of a complete decommissioning of CDF services on Fermilab side. An access system has been designed and tested to submit CDF analysis jobs, using CDF software distributed via CERN Virtual Machine File System (CVMFS) and requesting delivery of CDF files stored on CNAF tapes, as well as data present only on Fermilab storage archive. Moreover, the availability and the correctness of all CDF data stored on CNAF tapes has been verified. This paper describes all these recent evolutions in detail, presenting the future plans for the LTDP project at CNAF.
