Authors: He Wei , Shi Yichao , Kong Dewei 
Published: June 2019

Purpose
The construction industry is characterized by a long construction period, high cost and many uncontrollable factors. The owners and contractors are increasingly focusing on the efficiency of their construction and costs in pursuit of greater economic benefits. However, current methods used in the construction period and cost optimization analysis with multiple constraints the have their own limitations. Therefore, this study aims to propose a combination of genetic algorithm (GA) and building information modeling (BIM) to construct a five-dimensional construction duration-cost optimization model with the advantages of optimization and simulation for optimization.

Design/methodology/approach
This design first analyzed the characteristics of changing construction period and cost and then improved the genetic mechanism and the data processing method in the GA according to the aforementioned characteristics. Then, BIM technology was combined with GA to testify the feasibility of the model in the practical engineering project.

Findings
The result proved that this new method was reasonable and effective in dealing with the complicated problem of period and cost. GA accelerated the optimization process and yielded a reliable Pareto solution. BIM technology simulated the construction process before construction to increase the feasibility of the construction scheme.

Originality/value
This method not only can rapidly provide the best construction period/cost decision to the architect according to the previous working period/cost or contract data that can meet the demands of the architect but also visualize the construction and give a dynamic schedule of the project.

PurposeThe purpose of this paper is to investigate the effect of service quality on graduates’ satisfaction as perceived by Middle East University (MEU) graduates.Design/methodology/approachThis research is cross-sectional and aims to explore the effect of service quality dimensions (academic staff, administration, classrooms and library services) on graduates’ satisfaction. Data were collected from 399 graduates. After confirming validity, reliability and normality of the data, and the correlation between variables, multiple regressions were used to test the hypothesis.FindingsThe results show that all service quality dimensions are highly implemented by the MEU. The relationships between all service quality dimensions and graduates’ satisfaction are strong. Finally, results show that all service quality dimensions affect graduates’ satisfaction.Research limitations/implicationsTo generalize the results of this research, further studies are recommended to be carried out on other universities especially in Jordan. Testing the perception and satisfaction of other universities, stakeholders will help to improve service quality and to gain suitable competitive strategies.Practical implicationsService quality is a key driver for universities’ sustainable competitive advantage; therefore, dimensions of service quality should be included within universities plan, strategies and daily activities.Social implicationsConsidering service quality in higher education improves countries’ economic development, quality of life and well-being. All corporate social responsibility pillars (social, economic, environmental responsibilities and national and international regulation and norms) should be adapted and adopted within services quality systems and programs.Originality/valueMost of previous studies were carried out to test the students’ perception while this research is dedicated to explore graduates’ perception regarding service quality offered by the MEU.
Child trafficking crime and means of fighting it: Egypt as a case study
Authors: Rashad Suzi Mohamed 
Published: June 2019

Purpose
This paper aims to explore the factors leading to the phenomenon of child trafficking in Egypt, how deeply it runs through the Egyptian society and evaluate the state’s efforts to combat it.

Design/methodology/approach
This research paper uses a case study method applied to the phenomenon of child trafficking in the Arab Republic of Egypt, and how the State is fighting it. The general policy approach is also used to clarify the State’s plans, programs and legislation in addressing the phenomenon of child trafficking, evaluate those policies and analyze the international documents.

Findings
The research paper concluded that child trafficking in Egypt represents a serious phenomenon, which stems from social, economic and cultural reasons. Even though the Egyptian Government exerts relentless efforts to fight this crime, all attempts have proven insufficient due to the lack of coordination between the concerned parties and low funds, in addition to the feeble services offered to the victims.

Practical implications
This study sheds light on a very perilous phenomenon in the Egyptian society; an international one with intricate magnitudes, upon which the State must concentrate more and eradicate it.

Originality/value
The study contributes to drawing the attention of decision makers in Egypt to the dangers of this phenomenon, and to the points of strength and weaknesses of the government’s efforts against it.
Electro-thermal simulation and fabrication of LTCC hotplate with lead-free interconnects
Authors: Kharbanda D.K. , Suri N. , Khanna P.K. 
Published: June 2019

Purpose
The purpose of this paper is to explore a new possibility of providing high-temperature stable lead-free interconnections for low-temperature co-fired ceramics (LTCC) hotplate. For gas-sensing application, a temperature range of 200°C-400°C is usually required by the sensing film to detect different gases which imply the requirement of thermally stable interconnects. To observe the effect of parameters influencing power of the device, electro-thermal simulation of LTCC hotplate is also presented. Simulated LTCC hotplate is fabricated using the LTCC technology.

Design/methodology/approach
The proposed task is to fabricate LTCC hotplate with interconnects through vertical access. Dedicated via-holes generated on the LTCC hotplate are used to provide the interconnections. These interconnections are based on adherence and bonding mechanism between LTCC and thick film. COMSOL software is used for finite element method (FEM) simulation of the LTCC hotplate structure.

Findings
Thermal reliability of these interconnections is tested by continuous operation of hotplate at 350°C for 175 h and cycling durability test performed at 500°C. Additionally, vibration test is also carried out for the hotplate with no damage observed in the interconnections. An optimized firing profile to reproduce these interconnections along with the experimental flowchart is presented.

Research limitations/implications
Research activity includes design and fabrication of LTCC hotplate with metal to thick-film based interconnections through vertical access. Research work on interconnections based on adherence of LTCC and thick film is limited.

Practical implications
A new way of providing lead-free and reliable interconnections will be useful for gas sensor fabricated on LTCC substrate. The FEM results are useful for optimizing the design for developing low-power LTCC hotplate.

Originality/value
Adherence and bonding mechanism between LTCC and thick film can be used to provide interconnections for LTCC devices. Methodology for providing such interconnections is discussed.
How natural remanent magnetization of basaltic units can dominate the reduced to pole magnetic value: A case study from the Faroe Islands
Authors: Ziska Heri , Williamson Paul , Eidesgaard Óluva Reginsdóttir 
Published: June 2019

ABSTRACTEarly attempts to utilize magnetic data to understand the volcanic and subvolcanic succession on the Faroese Continental Shelf have shown that conventional interpretation and modelling of magnetic data from this area leads to ambiguous results. Interpretation of the aeromagnetic data on the Faroese Continental Shelf shows that some previously identified basement highs coincide with reduced‐to‐pole magnetic highs, whereas others coincide with negative or mixed magnetic features. Similarly, igneous centres are characterized by different polarity magnetic anomalies. Palaeomagnetic analysis of the onshore volcanic succession has demonstrated that the thermoremanent magnetization of the basaltic lavas is stronger than the induced magnetism, and both reversely and normally magnetized units are present. We have tested this with 2½D profile modelling using the palaeomagnetic information to correlate high‐amplitude magnetic anomalies with basalt successions containing changes in magnetic polarity. This approach has enabled us to map the termination of the differently magnetized units offshore and thereby extend the mapping of the Faroe Island Basalt Group on the Faroese Platform and into adjacent areas.

Published: June 2019

SummaryMaternally heritable symbionts are common in arthropods and represent important partners and antagonists. A major impediment to understanding the mechanistic basis of these symbioses has been lack of genetic manipulation tools, for instance, those enabling transgenic GFP expression systems for in vivo visualization. Here, we transform the ‘son‐killer’ reproductive parasite Arsenophonus nasoniae that infects the parasitic wasp Nasonia vitripennis with the plasmid pOM1‐gfp, re‐introduce this strain to N. vitripennis and then used this system to track symbiont life history in vivo. These data revealed transfer of the symbiont into the fly pupa by N. vitripennis during oviposition and N. vitripennis larvae developing infection over time through feeding. A strong tropism of A. nasoniae to the N. vitripennis ovipositor developed during wasp pupation, which aids onward transmission. The symbiont was also visualized in diapause larvae. Occasional necrotic diapause larvae were observed which displayed intense systemic infection alongside widespread melanotic nodules indicative of an active but failed immune response. Our results provide the foundation for the study of this symbiosis through in vivo tracking of the fate of symbionts through host development, which is rarely achieved in heritable microbe/insect interactions.

Published: June 2019

AbstractFootwear impressions are one of the valuable physical evidence encountered at crime scenes and its identification can facilitate narrowing down the suspects and establishing the identity of the criminals. The technique of electrostatic lifting (ESL) dust shoeprints at crime scenes is well established with scenes of crime examiners. And in the procedure, the recovery of the original item containing the impression should be made as good as it can and not damage the marks. In this study, the different particle sizes of SiO2 were used to simulate dust and light soil residues, comparing different particle sizes and electrode positions were used to compare the adsorption ability on the surface of electrostatic lifting film in high‐voltage electrostatic field for the collection of shoeprints. The results indicated that lifting film in electrostatic field will be pressed down to the dust surface, the compaction and electrostatic adsorption force will vary with the distance between the high‐voltage electrode and film surface. Reducing the distance can increase the electric field strength near the lifting film, and the adsorption capacity of Mylar aluminum‐plating film to dusts can be improved significantly. Adsorption capacity of the lifting film was related to the size of dust particles and significantly improved with the increase of the particle charge. The optimum distance which can get the best adsorption capacity between the electrode and film surface is from 10 to 15 mm.

Published: June 2019

AbstractOsteoporosis is a common metabolic bone disease that is often seen in bedridden patients and astronauts. Long‐term bed rest and nonweight bearing tend to induce disuse osteoporosis. Calcium supplements are commonly used to help treat disuse osteoporosis along with medications, most of which are calcium carbonate based, but they have poor absorption effects. In this study, we prepared a novel Auricularia auricula peptide–calcium complex (AP–Ca) and evaluated its protective effects on disuse osteoporosis. In vitro assays showed that AP–Ca significantly increased the contents of calcium (P < 0.05) and the activity of alkaline phosphatase (AKP; P < 0.05) of osteoblasts cultured in a two‐dimensional‐rotating wall vessel. Meanwhile, supplementation with AP–Ca also inhibited the production of pro‐inflammatory factors induced by the loss of stress, especially TNF‐α (P < 0.05). In vivo, a mouse tail suspension (TS) model was established, and the results showed that AP–Ca helped to improve bone mineral density, bone mineral content, and bone organic content in TS mice and effectively alleviated the alteration of enzymes related to bone metabolism, including AKP (P < 0.05) and serum tartrate‐resistant acid phosphatase (P < 0.05), to avoid more serious bone loss induced by TS. Furthermore, we found that AP–Ca downregulated the bone resorption‐associated pro‐inflammatory genes interleukin‐1 (IL‐1), tumor necrosis factor‐α, and IL‐6 by 59.53 ± 3.55%, 48.01 ± 5.68%, and 40.00 ± 5.89%, respectively (P < 0.05). In conclusion, AP–Ca showed potential to suppress bone loss induced by disuse and might be considered a new alternative to reduce the risk of disuse osteoporosis.Practical ApplicationThis peptide–calcium complex supplement exhibited protective effects on the bone loss induced by disuse, which provided a new alternative for patients and astronauts to reduce the risk of disuse osteoporosis.

Authors: Wang Cheng , He Liwen , Xing Yaqi , Zhou Wei , Yang Fuyu , Chen Xiaoyang , Zhang Qing 
Published: June 2019

SummaryNeolamarckia cadamba is not only a fodder of high nutritional value, but also a source of natural antimicrobial agent. The silage quality of high moisture alfalfa and stylo with or without N. cadamba leaves (NCL) was investigated, and microbial community after ensiling was analysed. Results showed that the silage samples with NCL have lower pH (4.32 versus 4.88, 4.26 versus 4.71 in alfalfa and stylo silage, respectively), ammonia‐N content (67.5 versus 146, 42.2 versus 95.1 g kg−1 total N) and higher lactic acid (13.3 versus 10.4, 17.3 versus 13.6 g kg−1 dry matter), true protein N (592 versus 287, 815 versus 589 g kg−1 total N). The addition of NCL also influenced the bacterial community distribution. The relative abundance of Clostridium and Enterobacter decreased, whereas Lactobacillus abundance increased when NCL was added. In conclusion, NCL could inhibit undesirable microorganisms in high moisture alfalfa and stylo silage. Mixing with NCL could be a feasible way to improve the quality of silage.
Cell density‐dependent auto‐inducible promoters for expression of recombinant proteins in Pseudomonas putida

Published: June 2019

SummaryInducible promoters such as Plac are of limited usability for industrial protein production with Pseudomonas putida. We therefore utilized cell density‐dependent auto‐inducible promoters for recombinant gene expression in P. putida KT2440 based on the RoxS/RoxR Quorum Sensing (QS) system of the bacterium. To this end, genetic regions upstream of the RoxS/RoxR‐regulated genes ddcA (PRox132) and PP_3332 (PRox306) were inserted into plasmids that mediated the expression of superfolder green fluorescent protein (sfGFP) and surface displayed mCherry, confirming their promoter functionalities. Mutation of the Pribnow box of PRox306 to the σ70 consensus sequence (PRox3061) resulted in a more than threefold increase of sfGFP production. All three promoters caused cell density‐dependent expression, starting transcription at optical densities (OD578) of approximately 1.0 (PRox132, PRox306) or 0.7 (PRox3061) as determined by RT‐qPCR. The QS dependency of PRox306 was further shown by cultivating P. putida in media that had already been used for cultivation and thus contained bacterial signal molecules. The longer P. putida had grown in these media before, the earlier protein expression in freshly inoculated P. putida appeared with PRox306. This confirmed previous findings that a bacterial compound accumulates within the culture and induces protein expression.

AbstractPlatform carbonates diagenesis in salt basins could be complex due to potential alterations of fluids related and non‐related to diapirism. This paper presents the diagenetic history of the Hettangian to Pliensbachian platform carbonates from the Tazoult salt wall area (central High Atlas, Morocco). Low structural relief and outcrop conditions allowed to define the entire diagenetic evolution occurred in the High Atlas diapiric basins since early stages of the diapiric activity up to their tectonic inversion. Precipitation of dolomite and calcite from both warmed marine‐derived and meteoric fluids characterised diagenetic stages during Pliensbachian, when the carbonate platforms were exposed and karstified. Burial diagenesis occurred from Toarcian to Middle Jurassic, due to changes of salt‐induced dynamic related to increase in siliciclastic input, fast diapir rise and rapid burial of Pliensbachian platforms. During this stage, the diapir acted as a physical barrier for fluid circulation between the core and the flanking sediments. In the carbonates and breccias flanking the structures, dolomite and calcite precipitated from basinal brines, whereas carbonate slivers located in the core of the structure, were affected by the circulation of Mn‐rich fluids. The final diagenetic event is characterised by the income of meteoric fluids into the system during uplift caused by Alpine orogeny. These results highlight the relevant influence of diapirism on the diagenetic modifications in salt‐related basins in terms of diagenetic events and involved fluids.

Predicting intervention priorities for wildlife conflicts

Published: June 2019

AbstractThere is growing interest in developing effective interventions to manage socially and environmentally damaging conservation conflicts. There are a variety of intervention strategies that can be applied in various contexts, but the reasons one type of intervention is chosen over another remain underexplored. We surveyed conservation researchers and practitioners (n = 427) to explore how characteristics of conflicts and characteristics of decision makers influence recommendations to alleviate conservation conflict. Using a full‐factorial design, we experimentally manipulated 3 aspects of the descriptions of 8 different wildlife‐conflict scenarios (development status of the conflict country, conflict framing, and legality of killing wild animals) and recorded which of 5 intervention types (wildlife impact reduction, awareness, enforcement, economic incentives, or stakeholder engagement) respondents prioritized. We also recorded information on respondents’ demographic and disciplinary backgrounds. Stakeholder‐based interventions were recommended most often in the survey and in written feedback. However, when we fitted multinomial mixed logit models with fully completed scenario responses (n = 411), recommendations were influenced by small changes in the details of conflict and differed according to respondent characteristics. Enforcement and awareness interventions were prioritized relatively more for conflicts in more highly developed nations and by respondents with more natural science backgrounds and relatively less experience with conflict. Contrastingly, economic interventions were prioritized more when wildlife killing was described as illegal. Age, gender, and development status of the respondent's home country also predicted some intervention decisions. Further, interrogating the influences shaping conservation decision making will further helps in the development of evidence‐informed interventions.
