Do Employees Snooze or Strike Back to Injustice?
This study aims to investigate the relationship between the perceptions of injustice and revengeful intentions among first- person (revengeful intention by the victim), second-person (revengeful intention for the sake of a close friend), and third- person (revengeful intention for the sake of an acquaintance). A questionnaire survey was used to collect data from 154 respondents. The findings showed that interactional injustice is associated positively with first-person revenge, whereas distributive and procedural injustice lead to second-person and third-person revengeful intentions. This study offers important insights about the broader impact of injustice which goes beyond the victim and explains how it ignites negative feelings among the non-victim as well
Individual Compassion Leading to Employees’ Performance: An Empirical Study from Pakistan
In social sciences “compassion” is considered as an impactful attribute of employees’ satisfaction and wellbeing. People demonstrate compassion for others in socially interacting environments like an organization. As organizational people interact with each other therefore they show compassion towards each other. In such a manner compassion becomes an attribute of organizational culture if organizations themselves promote and support compassion at workplace. Compassion being a source of employee satisfaction may increase his/her performance or may divert employee’s attention from task accomplishment. This possibility has inspired this study to empirically test the effect of compassion at workplace on employees’ performance. Moreover, an indirect effect of compassion through intrinsic motivation on performance is also tested in this study to elaborate how compassion at workplace intrinsically motivates employees to enhance their performance. To test these relationships, data from 94 respondents have been analyzed quantitatively. The findings of the study supported that compassion enhances employee-performance, specifically the contextualperformance. Moreover, intrinsic motivation also moderates compassion-performance relationship. Compassion at workplace even enhances employees’ task-performance when moderated by intrinsic motivation. This study provided empirical evidence that compassion at workplace can enhance employee-performance; contextual as well as task-performance
Prevalence of refractive errors and their association with socio demographic characteristics in pediatric patients attending tertiary eye care centre
Background: Uncorrected refractive errors are one of the major culprits of visual impairment among children in our country. Children included in school going age groups i.e., 6-16 years, represent 25% of population in developing countries. They fall in the category of preventable age group for correction of refractive errors. This paper describes the salient features and results of the cross-sectional study conducted to determine the prevalence of refractive errors and their association with socio demographic characteristics in pediatric population objective were to study the prevalence of refractive errors and their association with socio demographic characteristics in pediatric patients attending tertiary eye care centre.Methods: The cross-sectional study was conducted for a period of one year among children in 0-16 years age group and a total of 444 patients were included. All children were examined by ophthalmologists and refraction was done by optometrists. Data was analysed using web-based software open epi version 3.01.Results: Prevalence of refractive errors was found to be 29.5%. Amongst the socio demographic factors, there was a significant association of age and literacy with refractive errors whereas gender and residence were not found to be significant.Conclusions: Refractive errors are an important preventable cause of childhood ocular morbidity. Schools are an excellent platform to educate children and their parents regarding eye care and signs of ocular morbidity due to refractive errors. Health education activities in schools need to be intensified
Mechanistic insights into strigolactone biosynthesis, signaling and regulation during plant growth and development
Strigolactones (SLs) constitute a group of carotenoid-derived phytohormones with butenolide moieties. These hormones are involved in various functions, including regulation of secondary growth, shoot branching and hypocotyl elongation, and stimulation of seed germination. SLs also control hyphal branching of arbuscular mycorrhizal (AM) fungi, and mediate responses to both abiotic and biotic cues. Most of these functions stem from the interplay of SLs with other hormones, enabling plants to appropriately respond to changing environmental conditions. This dynamic interplay provides opportunities for phytohormones to modulate and augment one another. In this article, we review our current mechanistic understanding of SL biosynthesis, receptors and signaling. We also highlight recent advances regarding the interaction of SLs with other hormones during developmental processes and stress conditions
A comparative analysis of toluidine blue with frozen section in oral squamous cell carcinoma
Background:Surgical excision of the primary tumor with safe margins remains the mainstay of treatment for oral cavity squamous cell carcinoma (OSCC). The standard of care for assessment of intraoperative margins is frozen section histopathology. Unfortunately the facility is not available at most centers in limited resource countries. Toluidine blue, a metachromatic dye, has been well described in clinical identification of malignant and premalignant lesion in the oral cavity. Considering this we decided to explore intraoperative use of toluidine blue staining, in comparison with frozen sections, for the assessment of tumor-free margins.
Methods:
After obtaining clearance from the in-house ethical review committee, a prospective study was conducted at Aga Khan University Hospital, Karachi, from August 15, 2009 to March 14, 2010. A sample of 56 consenting Patients with biopsy-proven OSCC were included in the study, giving us 280 tumor margins. Margins were analyzed using toluidine blue staining and frozen section histopathology. A receiver operator curve (ROC) was then applied to compare assessment of margin status by toluidine blue and frozen section.
Results:
Of the 280 examined margins 11 stained positive with toluidine blue, three were positive on frozen section biopsy, and three were positive on final histopathology. Toluidine blue staining had sensitivity and specificity of 100% and 97%, respectively. The diagnostic accuracy of toluidine blue was found to be 97.1% with a positive predictive value (PPV) of 27.2% and a negative predictive value (NPV) of 100%. Conclusions: Toluidine blue can be used as an effective screening modality for the assessment of intraoperative margins in resource limited environments and reducing the number of frozen section biopsies performed. Further by providing real-time clinical information within minutes it can reduce indirect costs such as operating room time. It may also be used as an ad hoc for frozen section biopsies where frozen section facilities are available

Relationship of tumor thickness with neck node metastasis in buccal squamous cell carcinoma: an experience at a tertiary care hospital
Introduction Squamous cell carcinoma is the most common malignancy of the head and neck, with the buccal mucosa being the most common site involved. Early locoregional metastasis is a hallmark of this disease, and early stage tumors may harbor metastatic nodes that are occult. Certain parameters can help identify high-risk patients for whom the pattern of occult nodal metastasis can be predicted. Tumor thickness is one such objective parameter. Objective To determine the relationship of tumor thickness with neck node metastasis in squamous cell carcinoma of the buccal mucosa. Methods A retrospective chart review of 102 patients with biopsy-proven squamous cell carcinoma of the buccal mucosa with N0 Necks was performed. All patients underwent tumor resection with neck dissection, and the tumor thickness was measured. Univariate and multivariate analyses were performed. Results A total of 102 patients, of which 73.53% were males and 26.47% were females. The mean age of the patients was 49.3 11.1 years. It was found that the risk of neck node metastasis in buccal squamous cell carcinoma increases 35.5 times for a tumor thickness 2 mm, and the risk of neck node metastasis in buccal squamous cell carcinoma decreases by 0.58 times for each centimeter decrease in tumor size, while the rate of occult neck lymph node metastasis was found to be 37%. Conclusion We conclude that tumor thickness is significantly related with neck nodal metastasis in buccal squamous cell carcinoma, considering the age of the patient and the size of the tumo
