Critical Issues in Large‐scale Change

The results of a study designed to investigate issues in large‐scale change efforts are presented. The sample for this study consisted of 398 individuals with expertise in the area of planned change. Individuals were asked to indicate the types of issues they perceived as having a positive or negative impact on large‐scale change programs in general. Respondents also provided data on 312 specific change efforts. Results indicate that several variables, including high industry competition, a high percentage of employee participation and the participation of employees from many organizational levels, may have a significant positive impact on the success of large‐scale change programs.
The Interlocking Oppressions of Employment-related Discrimination for Internationally Trained Engineers in Canada

Social work has a long history of engagement with immigrants and refugees. However, the demographic profile of immigrants to Canada and their needs are changing. The past few decades have seen an increase in the numbers of highly educated professional immigrants from non-traditional countries of immigration. Though not typically thought of in the social work profession as a vulnerable population, this group faces multiple oppressions in Canada. This article reports on the findings of 20 in-depth interviews with internationally trained engineers and their experiences of discrimination either while searching for work, or in the workplace after employment was secured. Two key findings that emerge from this paper have important insights for social work practice. The first indicates internationally trained engineers experience discrimination on multiple axes pertaining to their social identities. The second reveals that a few participants did not view themselves as victims of discrimination, even though they acknowledged discrimination to be at play when others like them were unable to secure jobs as engineers. The findings challenge traditional views of who constitute vulnerable populations and disrupt notions of immigrant populations needing social work intervention only at the point when they are unable to cope with their cultural and social adaptations. The findings highlight the need for social work education to train students in the areas of advocacy, anti-racism, and anti-oppressive practice in order to better meet the needs of these groups.
In vitro multiplication, micromorphological studies and ex vitro rooting of Hybanthus enneaspermus (L.) F. Muell. – a rare medicinal plant

Abstract Hybanthus enneaspermus is a rare medicinal plant. We defined a protocol for micropropagation, ex vitro rooting of cloned shoots and their acclimatization. Surface-sterilized nodal segments were cultured on Murashige and Skoog (MS) medium with different concentrations of 6-benzylaminopurine (BAP) and kinetin (Kin). Medium supplemented with 1.5 mg L−1 BAP was found optimum for shoot induction from the explants and 6.4±0.69 shoots were regenerated from each node with 97% response. Shoots were further proliferated maximally (228±10.3 shoots per culture bottle with 7.5±0.43 cm length) on MS medium augmented with 1.0 mg L−1 each of BAP and Kin within 4–5 weeks. The shoots were rooted in vitro on half strength MS medium containing 2.0 mg L−1 indole-3 butyric acid (IBA). The cloned shoots were pulse-treated with 300 mg L–1 of IBA and cultured on soilrite® in a greenhouse. About 96% of the IBA-pulsed shoots rooted ex vitro in soilrite®, each shoot producing 12.5±0.54 roots with 5.1±0.62 cm length. The ex vitro rooted plantlets showed a better rate of survival (92%) in a field study than in vitro rooted plantlets (86%). A comparative foliar micromorphological study of H. enneaspermus was conducted to understand the micromorphological changes during plant developmental processes from in vitro to in vivo conditions in terms of variations in stomata, vein structures and spacing, and trichomes. This is the first report on ex vitro rooting in H. enneaspermus and the protocol can be exploited for conservation and large-scale propagation of this rare and medicinally important plant.
Surgical dental treatment prior to liver transplantation

Oral-source infections are a potential threat for transplant candidates because oral diseases tend to be more severe and untreated in people who have received transplants. Although not yet scientifically proven, evaluation and dental treatment during the pre-transplantation period is recommended in order to prevent infections and resultant odontogenic-origin sepsis during the post-transplant period, when patients receive immunosuppressive therapy. Aim: To evaluate the invasive dental procedures for removing dental foci performed in patients scheduled for liver transplantation and its accompanying complications. Methods: The medical records of 33 preliver transplant recipients who were undergoing invasive dental procedures were reviewed, including their laboratory tests, special handling needs and resulting complications. Results: Fifty invasive dental procedures were carried out on the 33 patients. Three of them were subjected to basic periodontal treatment and 47 were subjected to multiple or simple extractions. Three surgical procedures resulted in postoperative complications. Conclusions: Surgical intervention to remove dental foci in liver disease patients requires careful clinical evaluation, laboratory tests, knowledge and skills in the use of local and systemic hemostatic procedures, and a partnership approach between dentists and physicians, in order to reduce the risk of complications.
How do T Tauri stars accrete

We conjecture that observed protoplanetary disc accretion rates may be explained with low viscosities which could be the result of hydrodynamic turbulence. We show that viscosities parameterized in the usual way with $\alpha \gtrsim 10^{-4}$, comparable to values suggested for hydrodynamic turbulence, can explain the observed accretion rates and lifetimes with plausible inner disc surface densities. Our models are also in better agreement with surface density estimates of the minimum mass solar nebula than models with rapid transport for a given mass accretion rate, such as recent models of accretion driven by magnetic winds. The required surface densities are a natural result of the protostellar infall phase, as long as non-gravitational transport is limited. We argue that, in addition to possible non-ideal magnetic transport due to disc winds possibly modified by the Hall effect, the effects of low-viscosity hydrodynamic accretion deserve more consideration.
Tobacco Smoking and Cancer Types: A Review

Objective: Tobacco smoking is one of the causes of the incidence and mortality of cancer in the world. This study aimed to review the relationship between TS and especially the use of cigarettes with common cancers of various organs of the body. Methods: This study was conducted in English by November 2017 through a search in databases of the PubMed, Scopus and Web of Science. The search strategy included the key words "cancer", "tobacco smoke", "tobacco smoke", and "smoking. " Articles that looked at the relationship between each type of cancer and smoking were entered into the study and summarized in Review. Results: Tobacco smoking is associated with an increased risk of lung cancer, Upper aerodigestive tract, esophagus, stomach, bladder, kidneys, colorectal, prostate, and pancreas. However, further studies are needed to confirm the association between Tobacco smoking and liver, cervical, brain, gallbladder, Hodgkin’s disease, non-Hodgkin’s lymphoma and hematologic malignancies. However, Tobacco smoking plays a protective role in the development of thyroid cancers, skin and Kaposi’s sarcoma. Conclusions: Given that almost all of the risk factors for most cancers are Tobacco smoking, increasing the public’s awareness of the harmful effects of smoking, implementing programs and policies to reduce smoking, can lead to a reduction in smoking and consequently reduce the resulting harmful consequences.

The Social and Private Costs of Retail Payment Instruments: A European Perspective

The European Central Bank (ECB) carried out a study of the social and private costs of different payment instruments with the participation of 13 national central banks in the European System of Central Banks (ESCB). It shows that the costs to society of providing retail payment services are substantial. On average, they amount to almost 1% of GDP for the sample of participating EU countries. Half of the social costs are incurred by banks and infrastructures, while the other half of all costs are incurred by retailers. The social costs of cash payments represent nearly half of the total social costs, while cash payments have on average the lowest costs per transaction, followed closely by debit card payments. However, in some countries, cash does not always yield the lowest unit costs. Despite countries’ own market characteristics, the European market for retail payments can be grouped into fi ve distinct payment clusters with respect to the social costs of payment instruments, market development, and payment behaviour. The results from the present study may trigger a constructive debate about which policy measures and payment instruments are suitable for improving social welfare and realising potential cost savings along the transaction value chain.
Predicting Bank Credit Risk: Does Board Structure Matter?

The study investigates the predictors of credit risk in the universal banking industry with panel data from universal banks in Ghana and finds that leverage, assets (size), loan loss provision, board size, board independence, and the number of executive directors on the board of a bank are the predictors of its credit risk. Based on these results, the study concludes that board structure matters in credit risk management of universal banks in Ghana. The recommendation is that banks could improve their credit risk management by formulating policies around these factors.
Performance characteristics according to the channel length and magnetic fields of cylindrical Hall thrusters

Performance characteristics of low power cylindrical Hall thrusters are investigated in terms of the length of the discharge channel. Thrust, efficiency, discharge current, and propellant utilization are evaluated for different channel lengths of 19, 22, and 25 mm. It is found that the propellant utilization and ion energy distribution function are strongly associated with the channel length. Increase of thrust and efficiency are also found with increasing channel lengths. These characteristics of the thruster are interpreted with possible generation of multi-charged ions due to increased residing time within the extended space inside the channel.
Observational signatures of a warped disk associated with cold-flow accretion

We present MUSE observations of the field of the quasar Q0152$-$020 whose spectrum shows a Lyman limit system (LLS) at redshift $z_{\rm abs} = 0.38$, with a metallicity Z $\gtrsim 0.06$ Z$_\odot$. The low ionization metal lines associated with the LLS present two narrow distinct absorption components with a velocity separation of 26 km ${\rm s}^{-1}$. We detect six galaxies within 600 km ${\rm s}^{-1}$ from the absorption redshift; their projected distances from the quasar sightline range from 60 to 200 kpc. The optical spectra of five of these galaxies exhibit prominent nebular emission lines, from which we deduce extinction-corrected star formation rates in the range SFR = 0.06-1.3 M$_\odot$~yr$^{-1}$, and metallicities between 0.2 Z$_\odot$ and Z$_\odot$. The sixth galaxy is only detected in the stellar continuum. By combining our data with archival Keck/HIRES spectroscopy of the quasar and HST/WFPC2 imaging of the field, we can relate absorption line and galaxy kinematics; we conclude that the LLS is most likely associated with the galaxy closest to the quasar sight-line (galaxy "a"). Our morphokinematic analysis of galaxy "a" combined with the absorption line kinematics supports the interpretation that one of the absorption components originates from an extension of the stellar disk of galaxy "a", while the other component may arise in accreting gas in a warped disk with specific angular momentum $\sim 3$ times larger than the specific angular momentum of the galaxy halo. Such warped disks are common features in hydrodynamical simulations of cold-flow accretion onto galaxies; the data presented here provide observational evidence in favour of this scenario.
Random versus fixed-site sampling when monitoring relative abundance of fishes in headwater streams of the upper colorado river basin

Abstract Native fishes of the upper Colorado River basin (UCRB) have declined in distribution and abundance due to habitat degradation and interactions with nonnative fishes. Consequently, monitoring populations of both native and nonnative fishes is important for conservation of native species. We used data collected from Muddy Creek, Wyoming (2003–2004), to compare sample size estimates using a random and a fixed-site sampling design to monitor changes in catch per unit effort (CPUE) of native bluehead suckers Catostomus discobolus, flannelmouth suckers C. latipinnis, roundtail chub Gila robusta, and speckled dace Rhinichthys osculus, as well as nonnative creek chub Semotilus atromaculatus and white suckers C. commersonii. When one-pass backpack electrofishing was used, detection of 10% or 25% changes in CPUE (fish/100 m) at 60% statistical power required 50–1,000 randomly sampled reaches among species regardless of sampling design. However, use of a fixed-site sampling design with 25–50 reaches greatly.
Stress and Burnout in Bicultural Teams in Hi‐Tech Industry

This study examined burnout, stress and work importance among 120 Israelis working in binational teams, using quantitative (questionnaire) and qualitative (semi-structured interview) methodologies. Based on the existential perspective, the study documented low levels of burnout despite high levels of stress, which were explained by the high perceived importance of the work. Hierarchical regression showed that importance moderated the effect of stress on burnout. Findings also revealed that the unexpected social stressors associated with cultural differences between team members were more stressful than the stressors associated with high-tech work.

Socio-economic factors influencing implementation of Njaa Marufuku Kenya programme for sustainable food security in Makuyu Division, Murang'a County

Food security has remained a major challenge for the governments around the world. Kenya in particular has suffered for long over food insecurity both in urban and rural areas. Studies have discovered that, despite the much effort by the government and donor agencies in funding food-based programs, implementation of the same has remained an issue. Makuyu division in particular has been under several famine interventions like World Food Programme, World Vision Kenya, and Njaa Marufuku Kenya among others. Despite the much effort of the said agencies, the area has remained vulnerable to hunger and poverty. In line with this, the study sought to investigate socio-economic factors influencing implementation of food-based programmers in the area of study. The study focused on the demographic characteristics, land accessibility, capacity building and income level of the program implementers. Descriptive survey was used to gather information from the programme implementers from a target population of the 180 members of the groups undertaking the project activities and four NMK government officers. A sample of 123 members selected from the eight NMK funded groups through stratified proportional simple random offered required information by responding to the provided questionnaires. The study instruments were validated prior to actual data collection by close consultation with research experts and peer students. A self help group different from the study population was used for pilot testing. The scores obtained from the pilot objects were correlated to determine the instruments reliability. Obtained raw data were systematically organized, coded, analyzed through descriptive statistics with aid of a computer Software Statistic Package for Social Scientists and finally presented using percentage, frequency distribution and cross tabulation tables. The research findings showed that demographic characteristics; gender, age, marital status and family size had great influence on implementation of NMK food-based programmes. Land accessibility; availability, size and ownership greatly influenced implementation of the NMK programme. The study also found that capacity building and the level of implementers' income were great influences of programme implementation. The study recommends for gender balance in funding and capacity development towards implementation of food-based programmes. The government should also check on the issue of land which the study found a barrier to the implementation of agricultural projects. Ŝ i r v , JYn ur .
The Interaction Hypothesis: A Critical Evaluation.

The oral interaction hypothesis, proposed by Long and investigated by Pica, in second language (L2) acquisition is critiqued. The interaction hypothesis advances two major claims about the role of interaction in L2 acquisition: (1) comprehensible input is necessary for L2 acquisitIon; and (2) modifications to the interactional structure o. conversations that take place in the process W. ' negotiating a communication problem help make input comprehensible to an L2 learner. Changes tnat have taken place since the initial formulation of the hypothesis are reviewed, as is evidence cited in support of the hypothesis. In view of theoretical arguments and empirical counter evidence, a revised version of the hypothesis is proposed. The revisions suggest a theoretical account of how input made comprehensible through interactional modification results in acquisition, and also takes into account the basic procedures of nc,ticing, comparison, and integration. Contains approximately 75 references. (LB) Reproductions supplied by EDRS are the best that can be made from the orig-nal document. THE INTERACTION HYPOTHESIS:A CRITICAL EVALUATION
A Study on Correlation of Risk-Taking and the Oral Production of English Majors in China

Risk-taking refers to the tendency to engage in behaviors that have the potential to be harmful or dangerous, yet at the same time provides the opportunity for some kinds of outcome that can be perceived as positive. Ely (1986) and Bang (1999) have mentioned the relationship between risk-taking and oral production in the process of English learning. However, few researches have set their foot into the correlation between risk-taking of English majors and their oral production. Hence, it is indispensable to carry out this study to fill the gap. The study aims to investigate the general situation of English majors’ risk-taking in oral production; how does risk-taking of English majors correlate with fluency, accuracy and complexity in oral production; what is the difference between high risk-taking and the low risk-taking of English majors in the oral production: fluency, accuracy and complexity? And if there exists some differences, how these related to risk-taking? The results show that the English majors’ risk-taking is at a relatively low level; there is a positive and strong correlation between risk-taking of English majors and the two aspects of oral production: fluency, accuracy, and there is no correlation between risk-taking and complexity; there exists difference between high risk-taking and low risk-taking in oral fluency and accuracy for English majors. The higher risk-taking subjects are able to produce more fluent and accurate sentences than the low risk-taking subjects. However, no difference has been found between high risk-taking and low risk-taking in the oral production of complexity.
Effect of Nanoparticle Surface Modification and Filling Concentration on Space Charge Characteristics in TiO2/XLPE Nanocomposites

This paper focuses on the space charge characteristics in TiO2/cross-linked polyethylene XLPE nanocomposites; the unmodified and modified by dimethyloctylsilane MDOS TiO2 nanoparticles were added to XLPE matrix with different mass concentrations 1 wt%, 3 wt%, and 5 wt%. The scanning electron microscope SEM showed that the MDOS coupling agent could improve the compatibility between TiO2 nanoparticles and XLPE matrix to some extent and reduce the agglomeration of TiO2 nanoparticles compared with unmodified TiO2 nanoparticles; the volume resistivity testing indicated that the volume resistivity of TiO2/XLPE nanocomposites was higher than Pure-XLPE and increased with the increase of filling concentrations. According to the pulsed electroacoustic PEA measurements, it was concluded that the space charge accumulation was suppressed by filling TiO2 nanoparticles and the distribution of electric field in samples was improved greatly. In addition, it was found that the injection of homocharge was more obvious in MDOS-TiO2/XLPE than that in UN-TiO2/XLPE and the homocharge injection decreased with the increase of filling concentration.
Revisiting influence of marketing effectiveness and environmental awareness on buying behaviour of green product: a SEM approach

Environmental sustainability become a prominent and unending issue in the third world economic countries such as Malaysia. Although, “green” and “go green” concepts were emphasized by academicians and practitioners to explain the need to save the earth but environmental consciousness is remain at beginning stage. Therefore, the purpose of this study is to determine green buying behaviour among undergraduate students using environmental awareness or concern and marketing effectiveness as independent variables and intention as a mediator. Total 375 usable questionnaires were used for the purpose of analysis. Our findings support the influence of environmental awareness and marketing effectiveness on the intention and influence of intention on buying behaviour. Similarly, environmental awareness and marketing effectiveness mediated by intention on buying behaviour. The results of this study can be used by public and marketers to encourage pro-environmental behaviours. The recommendation, limitation and conclusion are then discussed at the end of the paper
