In this study, interviewer-based questionnaires of 67 variables were administered to local fabricators and end-users of single-pot biomass stoves (SPBS) in Ghana. Additionally, two randomly selected traditional and improved SPBS were lab-tested using standard performance metrics. From the study, the relationship between fabricators and end-users was conceptualized based on selected indicators and assumptions. The study results indicated that the primary design resources for fabrication were patterns and templates, and that major challenges to fabrication were lack of training in design principles, standards and safety, poor emission efficiency and financial sustainability. Whereas end-users of improved SPBS were less affected by heat and smoke, end-users of traditional SPBS were mostly affected. From hypothesis test, because the calculated χ2cal = 24.05, and is greater than the tabulated χ2crit = 3.841, it is concluded that there is a relationship between heat, smoke effect and gender, and that female end-users of traditional SPBS were particularly affected during cooking. The traditional SPBS emitted more CO2 and CO than improved SPBS. Comparatively, 38% more end-users of traditional SPBS observed charcoal ash residue in the cooking area than improved SPBS users. Four basic practices of managing ashes from SPBS are developed. Finally, a fabricator and end-user framework are developed for energy sustainability and quality improvement.

To understand the factors leading to success in programming courses it is helpful to examine the background of successful students. In this study we examined the influences of general ability, computer-related and general experience, perception of programming performance, and gender. We also studied the relationship between the form of classroom instruction and performance of successful students. Results indicated that the most successful students did not progress far along the chain of cognitive accomplishments of programming, gained their skills primarily from classroom instruction, and were not necessarily high in general ability or owners of home computers. These results have strong implications for classroom instruction.

Purpose – The purpose of this paper is to investigate the relationship between intellectual capital (IC), categorized in terms of four sub-constructs – namely, human capital (HC), relational capital (RC), innovation capital (InnC) and process capital (PrC) – and business performance in the agribusiness industry. Design/methodology/approach – Based on a sample of international agribusiness companies observed over a five-year period, this paper uses correlation and multiple regression analysis to test for the existence of a positive relationship between each IC component and conventional business performance metrics. Findings – The empirical results support the hypotheses that RC and PrC have a positive impact on corporate performance. Counter to the expectations, InnC by itself is negatively associated with performance. Results also failed to confirm the hypothesis that HC directly and positively affects performance. However HC positively moderates the relation between InnC and performance, which suggests that firms that heavily invest in HC are better placed to gain returns from their research and development (R & D) investments. Originality/value – This study expands the existing research on the link between IC and performance by adding fresh evidence from a highly knowledge-intensive sector which has been under-researched thus far. It may also contribute to the specific literature on R & D and performance as it uncovers that the value-generating effect associated with R & D investments is contingent on the levels of HC.

The article presents the results of the study of the personal socio-psychological features in the bailiff service officers. The study involved 675 bailiff executors, 410 men (60.7%) and 265 women (39.3%) aged 21 to 59 years. In our study, we used a number of diagnosis tools, such as MMPI - a multifactorial questionnaire for the personality study, Brief Indicative Selection Test developed by V.N. Buzin and E.F. Wonderlic, K. Leonhard - N. Shmishek diagnostic test to determine character accentuations, the projective technique "House-Tree-Person" by J. Book, as well as observations and interviews. Our study revealed mean indicators of intellectual development level related to the range of values "above average", absence of pronounced character accentuations with a tendency to hypertension and demonstrativeness and risks of a tendency to depression and rigidity. The analysis showed the relationship of certain characteristics to the subjects’ age and gender. Factor analysis identified the major social and psychological personality traits of bailiffs which are the most significant for their professional activities. The study results can be used for professional psychological selection of bailiff service officers, their psychological support and the development of techniques in order to prevent burnout syndrome and professional deformation.

The study examined the relationship between retention strategies and performance of organisations in the FOBTOB industry. The effect of retention strategies on performance of unionised organisations in the FOBTOB industry was also examined. The survey research design was adopted. A total of 420 research subjects were drawn from fourteen respondent companies using the simple random sampling and proportional stratified sampling techniques. The research instrument was subjected to validity and reliability tests. The domain of validity also called intrinsic validity was used for the validity estimate as well as content validity. The domain of validity was obtained by calculating the square root of reliability. The Cronbach Alpha was used for the reliability test. It was hypothesised that that there is no relationship between retention strategies and performance of unionised organisations in the industry studied. The result of hypothesis test shows that retention strategies are statistically and significantly related with all the measures of performance, such as growth in number of employees (r =0.370; p< 0.01); profitability (r = 0.264; p< 0.01); innovativeness (r = 0.279; p< 0.01); performance stability (r = 0.241; p< 0.01); and rate of sales (r = 0.207; p< 0.01) while the Chisquare test result is (χ2=231.507, df=3, p< 0.01) confirmed the results of the correlation test. It was also hypothesised that retention strategies do not affect performance of unionised organisations in the Industry studied. The results of the regression test revealed that retention strategies affect performance of unionised organisations in the FOBTOB industry. It is recommended that organisations should not rely only on intrinsic variables to influence employee retention; rather, a combination of both intrinsic and extrinsic variables should be considered as an effective retention strategy if optimal performance indices are to be achieved

With the continuing digital revolution steered by the Internet, organizations are moving towards information technology integration to improve their performance. Regrettably, these developments have in no way been all-inclusive. The health gap between public institutions in first, second and third world nations has broadened. Public organizations in second and third world nations are characterized by poor performance. This study sought to establish the moderating effect of organizational characteristics on the relationship between information technology and performance of public hospitals in Kenya.  The study used Technology Organization Environment (TOE) theory. The study was guided by explanatory and cross-sectional research design. The target population was 98 public hospitals in Kenya. Multi-stage sampling technique was used to select a sample size of 294 respondents. Primary data was collected using semi-structured questionnaires. For data analysis, descriptive statistics and multiple regression analyses were used. The study results established that organizational characteristics moderated the relationship between information technology integration and performance of public hospitals in Kenya. Therefore, study concluded that organizational characteristics play a major role in an organization’s adoption and utilization of information technology integration. The study recommends technologies should be customized to fit the type of organizational characteristics for better performance.

Ecological footprint is an estimation analysis or measure individual consumption behaviour resulting in the environment. One of the factors which ecological footprint affects are knowledge of ecology concepts and gender. The objective of this research was to determine the relationship between student’s knowledge of ecology concepts to ecological footprint based on gender. This research was conducted on January-February 2016. The method used was descriptive method with correlational study. The sample was simple random sampling about 104 students. The prerequisite test showed that the data was normal and homogen. The first hypothesis test using linear regression test and simple correlation. Regression model obtained Ŷ = 0.047–0.574X had a significant and linear relationship. The coefficient of correlation obtained was –0.72, which means there was a negative relationship between student’s knowledge of ecology concepts to ecological footprint. The coefficient of determination obtained was 0.518, which means student’s knowledge of ecology concepts contributed 51.8% to the ecological footprint. The second hypothesis test using t-test independent sample, significance value obtained was 0.123, which means that there was no significant ecological footprint difference between man students and woman students. The result of this study concluded that there was negative correlation between student’s knowledge of ecology concepts with ecological footprint and gender was no affect the student’s ecological footprint. The higher of knowledge of ecology concepts will reduce their ecological footprint and it will create a balance environment.

The use of ergogenic aids is common in sport, even among preadolescent athletes (8,15,25). The aim of this study was to investigate the relationship between preadolescents’ use of nutritional ergogenic aids (creatine and amino acids) and gender, age, athletic participation, and sport-relevant psychological factors (i.e., sport success motivation, task and ego orientation, self-efficacy). Two thousand four hundred fifty 11- to 13-year-old children participated in this study. Results suggest that substance use increases with age, especially among male preadolescents; that gender differences are particularly marked among older preadolescents; and that a high commitment to sport training represents a risk factor of ergogenic supplementation only when it is linked to certain psychological dispositions, such as a high ego orientation and a low task orientation.

Every company needs human resources with special skills, knowledge, and licenses in marketing products for effective work. Employee productivity is closely linked to their job loyalty and job satisfaction. Productivity can also be affected by other factors, including training and organizational communication. The purpose of this study is to assess the influence of training and organizational communication on job loyalty with job satisfaction as an intervening variable. This research was conducted at the Priority Banking Office of PT Bank Tabungan Negara from November 2020 to July 2021. The population in this study is 218 employees – an employee of PT Bank Tabungan Negara, who is under the Wealth Management Division with positions as Priority Banking Manager and Priority Banking Officer. Data collection was done through questionnaires submitted to each selected respondent. This research uses the approach of the Structure Equation Partial Model (SEM). Data analysis includes a validity test, rehabilitation test and hypothesis test with SEM-AMOS against 3 (three) variables. This study results showed that training and organizational communication has a positive and significant influence on job loyalty of PT Bank Tabungan Negara employees. In addition, training and organizational communication affect job satisfaction as an intervening variables. This effect is positive and significant. Job satisfaction as an intervening variable has a positive and significant effect on job loyalty. Job satisfaction indirectly influences the relationship between training and job loyalty and organisational communication and job loyalty.

Gender is not always immediately obvious online and this has excited interest from early on (e.g., Bruckman, 1993; Curtis, 1997). Sometimes, people have drawn extreme conclusions from this vagueness. For example, Mark Poster (1997) suggests that “one may experience directly the opposite gender by assuming it and enacting it in conversations” (p. 223). McRae (1996) writes, “mind and body, female and male, gay and straight, don’t seem to be such natural oppositions anymore ... The reason for this is simple: in virtual reality, you are whoever you say you are” (p. 245). Such statements imply that gender is simply a voluntary and unconstrained conscious performance. Other writers have concluded that such identity vagueness allows, or enhances, the formation of postmodern decentred or multiple selves (Kolko & Reid, 1998; Turkle, 1995). These arguments suggest that, when online, people are free of off-line conventions, restrictions, and power dynamics, and can experience hidden aspects of themselves, or create themselves, through an act of will and performance. Frequently, these positions are surrounded by a conflicting moral discourse, either suggesting that the Internet promotes freedom and true self-expression, or that it promotes bad faith and betrayal. However, easy voluntarism may not be common in practise. Although it is possible that people may present new identities, the categories they use and present within can remain unchallenged and may even intensify. After her praise of voluntarism, McRae (1996) points out that if someone plays a woman and wants to “attract partners as ‘female’ [they] must craft a description within the realm of what is considered attractive” (p. 250). Schaap (1999) likewise remarks on the relatively “strict rules on what constitutes a convincing female character and what a convincing male character.” So, although the gender of the person online may not match their gender off-line, the gender they choose usually exaggerates the conventions of attractive or good gender construction. As Kendall (1996) writes, “choosing one gender or another does nothing to change the expectations attached to particular gender identifications” (p. 217). Even if gender is simply a matter of performance, people will not experience life as the other gender or class does because they have to indicate which category they are impersonating via conventions, and thus tend to experience cliché, and reaction to cliché, rather than normal complexity. On MOOs (MUD [multiuser domain] object oriented), where Netsex can be important in reducing the ambiguities of presence and sustaining relationships, most women and men are adorned with an excess of the symbolism and roles of the gender and sexual discourse they participate within, and this may reinforce ideals of gender difference (Marshall, 2003). This seems to be the case even when people portray themselves as nonhuman. As an example of this supposed variance, McRae (1996) quotes a player on a kind of MOO in which people present themselves as anthropomorphic animals, saying there is a form of sex in which “the submissive partner is eaten at climax ... [B]ears and wolves are usually dominant. Foxes are sorta generally lecherous. Elves are sexless and annoyingly clever. Small animals are often very submissive” (p. 248). Even here, the relationship of size, bulk, aggression, and strength to dominance is not far from conventional constructions of male and female. This requirement to indicate gender by conventional referents may also lead people to portray their off-line gender in conventional terms as well. Clark (1998) notes this clichéd gender emphasis in her study of online teenage dating, while Herring (2000) writes that she “found that nearly 90% of all gendered behavior in six IRC [Internet relay chat] channels indexed maleness and femaleness in traditional, even stereotyped ways; instances of gender switching constituted less than half of the remaining 10%.” Conventions can also provide debate on women-only groups, where people can only be identified as female by their feminine behaviour unless they are checked by known links off-line. As it is possible to ignore the gender of those who contradict our expectations of gender, those expectations may grow stronger for not being challenged.
