The rationale of this article is to provide a method lending statistical support to the selection of TAs. The purpose is to determine the statistical significance of TAs through the derivation of associated significance (P) values. Design/Methodology/Approach: We demonstrate our methodology with reference to an original QFD case study aimed at improving the educational system in high schools in Pakistan; and then with five further published case studies obtained from literature. Mean weights of TAs are determined. Considering each TA mean weight to be a Test Statistic, a weighted matrix is generated from the VOCs’ importance ratings, and ratings in the relationship matrix. Finally using R, P-values for the means of original TAs are determined from the hypothetical population of means of TAs. Findings: Each TA’s...

Here, we assessed potential plant communities along an altitudinal gradient and their associations with different environmental drivers in the unexplored Manoor Valley (Lesser Himalaya), Pakistan. We have implemented various ecological techniques and evaluated phytosociological attributes in three randomly selected 50 m-transects within each stand (a total of 133) during different seasons for four years (2015–2018). This phytosociological exploration reported 354 plant species representing 93 different families. The results revealed that the Therophytic life form class dominated the flora, whereas Nanophyll dominated the leaf size spectra. There were a total of twelve plant communities identified, ranging from the lowest elevations to the alpine meadows and cold deserts. The maximum number of species were found in Cedrus–Pinus–Parrotiopsis ...

The sample was based on 124 students; 72 male and 52 female from 12 public sector secondary schools. The students were selected conveniently from 10 grade with age range from 13 to 18 years, (M=15.10, SD = .998). They were taught English as a compulsory subject included in the school curriculum. The assessment of vocabulary knowledge and reading comprehension of students was measured through four research instruments; Vocabulary Level Test, Word Associate Test, Morphological Knowledge Test and Reading Comprehension Test. Results showed that a high correlation occurred between depth of vocabulary knowledge and reading comprehension, but a moderate correlation was observed between breadth of vocabulary knowledge and reading comprehension. Regression analysis showed that vocabulary depth has high predictive power than voc...

In this age of globalization and scientific revolution, education has got more focus as a fundamental right of human. In Pakistan, substantial efforts are made, both in government and private sectors of education, to promote education. Resultantly, a huge number of educational institutions have been established. Both, parents and teachers, should feel the responsibility of providing the students with all the educational opportunities for the development as conscientious citizens. Design/Methodology/Approach: This article is an extension of the work by Iqbal et al., (2020), which focuses on exploring the strategies to improve secondary education. Iqbal et. al., (2020) used QFD methodology, and found out the Needs and Demands (N&Ds) of students and their parents; and then explored the Technical Solutions (TSs) to address these N&Ds. Findings: The results showed that ‘Teaching Behavior’ was highly important TS with weight of 71, and ‘Checked through Technical devices’ with f...

AU and RL rats were studied 24 h after bilateral nephrectomy (blood urea nitrogen, 128 +/- 13 mg/dl) or two thirds hepatectomy, respectively. The effects of postoperative fasting were assessed by comparison of normal rats (N) with control rats (N6) pair-fed to match the caloric intake of the AU and RL rats. Surgical/anesthetic effects were determined by comparison of N6 rats with sham-operated pair-fed rats (S6). The effects of AU or RL were obtained by comparison with S6 controls. Changes in mean body weight attributable to fasting (N6-N), surgical/anesthetic effects (S6-N6), acute uremia (AU-S6), and regenerating liver (RL-S6) were: -17.3 (P less than 0.001), -4.0 (P = NS), -4.5 (P less than 0.05), and -1.0 g/24 h (P = NS), respectively. Changes in mean serum T4 (N, 5.3 +/- 1.3 micrograms/dl) were: -1.0 (P = NS), -0.6 (P = NS), -0.9 (P less than 0.05), and -1.0 micrograms/dl (P less than 0.05), respectively. Changes in mean serum T3 (N, 53 +/- 23 ng/dl) were: -8 (P = NS), -18 (P less than 0.05), -10 (P = NS), and -14 ng/dl (P less than 0.05), respectively. The NP and CB receptor pools of the AU and RL rats were not significantly different from those of age-matched N rats (NP, 25 +/- 5 fmol/mg DNA; CB, 405 +/- 134 fmol/mg DNA). Chronically uremic (CU) rats 2 weeks after five sixths nephrectomy (blood urea nitrogen, 36 +/- 2 mg/dl) did not exhibit significant change in their extractable receptor pools. Complete starvation for 24 h (NO) or 72 h (NOO) generally resulted in marked reductions in receptor concentrations compared to those in age-matched N rats fed ad libitum: NP pool (N, 31 +/- 17 fmol/mg DNA): NO-N, -40% (P = NS); NOO-N, -59% (P less than 0.01); CB pool (N, 303 +/- 105 fmol/mg DNA): NO-N, -19% (P less than 0.05); NOO-N, -41% (P less than 0.001). These studies indicate that severe AU, moderate CU, and LR have relatively little effect on solubilized rat liver nuclear receptor concentrations. In contrast, complete starvation is a potent depressant of both nuclear receptor pools. In the surgical models of AU and LR, postoperative fasting was the primary cause of weight loss.(ABSTRACT TRUNCATED AT 400 WORDS)

Nowadays, increasing water scarcity is a major global challenge. Continuing improvements in water-use efficiency are essential for cotton production sustainability. Reduced irrigation in cotton could be a solution to water shortage in the arid climate without compromising the cotton yield. Therefore, a two-year field study was conducted to assess the effect of two levels of irrigation i.e., 50% and 100% of available water content (AWC) on the yield of four cotton genotypes (CIM-678, CIM-343, CRIS-613, and CYTO-510). The maximum seed cotton yield was observed in CIM-678, which was 2.31 and 2.46 Mg ha−1 under 100% AWC during 2018 and 2019, respectively, and was non-significantly reduced by 7.7 and 8.94%, owing to deficit irrigation. The maximum water use efficiency (WUE) of 0.55 and 0.64 Kg ha−1 mm−1 was observed under 50% AWC in CIM-678, which was significantly higher than WUE at 100% AWC during bo...

The objective of this research was to determine a suitable working speed for a gear-driven dibbling mechanism appropriate for a pepper transplanter, while considering agronomic transplanting requirements. The proposed dibbling mechanism consisted of two dibbling hoppers that simultaneously collected free-falling seedlings from the supply mechanism and dibbled them into soil. To enable the smooth collection and plantation of pepper seedlings, analysis was carried out via a mathematical working trajectory model of the dibbling mechanism, virtual prototype simulation, and validation tests, using a physical prototype. In the mathematical model analysis and simulation, a 300 mm/s forward speed of the transplanter and a 60 rpm rotational speed of the...

Theoretically, it is an additional perspective in the debate on effectiveness of different leadership styles in different environments for different purposes. It starts with analyzing contemporary theories of leadership and their derivative styles. Next, it discusses the major aspects of organizational environment coming from the broader culture of a country. Subsequently, it tries to provide a more balanced view in the debate on cause and effect of leadership styles and their effectiveness in specific organizational culture. In the empirical analyses the study analyzes the productivity, acceptance and sustainable success of different leadership styles in the organizations working in Pakistan. The data is collected both from business leaders and their relevant followers. The findings of study explai...

This study proposes that as employees’ work ethics are calibrated through ethical training, their MA increases, in turn affecting employees’ job performance. This experimental study is aimed at investigating the impact of MA, increased through ethical training, on employees’ job performance. Based on institutional theory, the multidimensional work ethic profile (MWEP) and strategic human resource management literature, it is hypothesized that MA of employees’ is positively correlated with employees’ performance and that this relationship is moderated by the age, gender and education level of the employees. In particular, the moral awareness component of ethical decision-making...

The overturning stability and vibration of upland crop machinery under development are important ... more The overturning stability and vibration of upland crop machinery under development are important issues for analysis because farms for upland crops are usually uneven, which may cause work-related fatalities, and vibration affects user comfort and reduces the durability of components. In this study, the overturning stability and vibration of a tractor-mounted radish collector were investigated to ensure safety during radish collection. To analyze lateral stability, the center of gravity (CG) of the tractor-mounted radish collector system was calculated mathematically. Then, a simulation was performed to determine the lateral overturning angles at different folding positions of the radish conveyor belt and load conditions, and the results were validated through tests. Vibration sensors were used to measure the vibration levels and the power spectrum density (PSD) was obtained to check the cyclic apparatuses of the major frequencies. The load conditions, different conveyor speeds, and...
