Understanding Adoption Intention of Mobile Shopping Applications
Authors: Gharaibeh Malik Khlaif , Gharaibeh Natheer Khlaif
Published: March 2021

This paper empirically explains the main determinants impacting user's intention to shop via mobile application in Jordan. This study modified innovation diffusion theory (IDT) and incorporates two new factors: perceived enjoyment and perceived risk. Data were obtained from 450 customers by using regression analysis for testing seven hypotheses. The results showed that relative advantage, compatibility, trialability, and observability are significantly associated with consumer decisions to adopt mobile shopping applications. Perceived enjoyment and perceived risk have a non-significant effect on the intention to use. Interestingly, complexity was found to be positively related to intention to use. This research confirms that IDT is a robust model when studying new technology or innovation like mobile shopping. The findings from this study are helpful for software engineers, retailers, service developers, and mobile marketers to raise the usage rate of this service among people.

The internet has paved the way for a revolution in the shopping industry via online platforms. As online shopping transactions become popular, it is increasingly important to understand the drivers that influence the consumers in availing such platforms. Furthermore, the differences between developed and developing economies are evident from socioeconomic, regulatory, and e-commerce disparities. Understanding such domain from a developing economies perspective is not well explored in the current literature. Thus, this study aims to identify the relationships among drivers of consumers in pursuing online shopping in a developing economy (i.e., the Philippines) using interpretative structural modeling. The study identified six drivers: “convenience/ease of use,” “competitive price,” “product availability,” “value of time,” “access to more information,” and “several payment options.” Results show that all drivers, except for “competitive price,” are closely interlinked to each other, such that initiatives must be simultaneously developed to address these drivers under resource constraints.
Accessing the Logistics Service Competitiveness
Authors: Tran Le Anh Duy , Pham Van Kien
Published: March 2021

Recently, Southeast Asia (SEA) has become a very attractive region for FDI from developed countries. This trend has led to the rapid development of logistics services. However, in the existing literature, there is very little empirical research to compare SEA countries like for example Thailand, Vietnam, Indonesia, and The Philippines. Current studies mainly focus on a single country or some typical industries. Therefore, a comprehensive model with various attributes able to compare which country is performing a better logistics service is still missing. For this reason, the authors conducted this study with the expectation of providing a model that uses attributes able to make it easier to compare and evaluate the attractiveness of logistics services in each country. To do so, the paper uses AHP theory to set up the research model and a questionnaire to obtain data from 23 experts in the logistics industry. Based on an analysis of the results, Vietnam is the most attractive destination for logistics services. This finding was driven by the importance of the government-related attributes. Thailand because of the country's cost competitiveness proved attractive. The results of the study make it easier for managers to assess and select the best suited country for logistics services.
A Modified Technology Acceptance Theory to Assess Social Commerce Technology Adoption
Authors: Momani Alaa M.
Published: March 2021

User acceptance and satisfaction are important factors when evaluating any technology. This paper investigates the key determinants that drive the adoption of social commerce within the Jordanian community. A modification to the Theory Of Acceptance And Use Of Technology was empirically validated by applying a quantitative survey questionnaire. Several statistical techniques were utilized to examine the modified model. The modified model showed that performance expectancy, effort expectancy, social influence, and enjoyment expectancy are significant influencers of behavioral intentions. Facilitating conditions and behavioral intentions also significantly influence the actual use behavior of social commerce by the Jordanian community sampled. The results indicated that the four proposed moderating variables affect the relation between the expectancy variables and the behavioral variables.

Association between estradiol levels and clinical outcomes of IVF cycles with single blastocyst embryo transfer
Authors: Polim Arie A. , Handayani Nining , Aprilliana Tri , Silvia Roza , Sirait Batara , Boediono Arief , Sini Ivan
Published: March 2021

Objective:

To determine the correlation of different serum estradiol levels on the trigger day with the clinical and laboratory outcomes of in-vitro fertilization (IVF) cycles comprising a single fresh top-quality blastocyst transfer.

Methods:

This was a retrospective observational study performed in Morula IVF Clinic Jakarta. Five hundred forty-two women were recruited and grouped according to their serum estradiol levels on the trigger day of follicular maturation as follows: <2 000 pg/mL, 2 000-2 999 pg/mL, 3 000-3 999 pg/mL, and ≥ 4 000 pg/mL. Clinical pregnancy and miscarriage rates were evaluated as the primary outcomes and embryology laboratory results as the secondary outcomes which consisted of the number of retrieved, mature, and fertilized oocytes, the total sum of derived embryos, and top-quality embryos at cleavage and blastocyst stage.

Results:

Clinical pregnancy and miscarriage rates did not differ among the groups (P>0.05). Nonetheless, the study demonstrated a positive correlation of the serum estradiol levels with the overall laboratory outcomes including the number of retrieved, mature, and fertilized oocytes, the total sum of derived embryos, and top-quality embryos at cleavage and blastocyst stage (P<0.001). The subject group with estradiol level of ≥4 000 pg/mL was superior to the other groups in its respective median number of retrieved, mature, fertilized oocytes, total derived embryos, and top-quality cleavage- and blastocyst-stage embryos.

Conclusions:

Although an apparent positive correlation is observed between estradiol levels and laboratory outcomes, serum estradiol level on hCG trigger day is not associated with the clinical outcomes of IVF.

Objective:

To investigate the combined therapeutic potential of Gymnema (G.) sylvestre and Pergularia (P.) daemia on letrozole-induced polycystic ovarian syndrome (PCOS) in rats.

Methods:

Thirty six healthy female Wistar rats with regular estrus cycles were randomly divided into six groups each of 6. Group I received 1 mL of 0.5% carboxyl methyl cellulose orally and served as the vehicle control group, while groups II to VI were treated with letrozole (1 mg/kg body weight p. o.) for 21 days to induce PCOS. After induction of PCOS, group II served as the PCOS control group, without treatment; group III received metformin (20 mg/kg body weight p. o.) as the standard group, and groups IV to VI received G. sylvestre (100 mg/kg body weight p. o.), P. daemia (300 mg/kg body weight p. o.), and the combination of G. sylvestre and P. daemia, respectively, for 28 days. Vaginal smears were collected from all rats daily throughout the study to determine the phases of the estrus cycle. After completing the treatment schedule, oral glucose tolerance test, serum lipid profile and reproductive hormonal analysis were carried out. Subsequently, the rats were sacrificed to collect ovary and uterus for histopathological examination.

Results:

The PCOS control rats showed a significant irregularity in the estrus cycle, hyperglycemia, and the altered serum lipid profile such as the increased low and very low density lipoprotein, triglyceride, and decreased high density lipoproteins. In addition, the PCOS control rats showed a significant increase in serum luteinizing hormone, testosterone, and estrogen, and decrease in follicle stimulating hormone and progesterone. These changes were significantly revoked in all the treatment groups. The test drugs also significantly reduced the gained ovary weight (P<0.001), and histopathology of the ovary showed almost normal ovary. Among the treatment groups, the group of combination treatment of G. sylvestre and P. daemia showed superior ameliorative results in PCOS parameters.

Conclusions:

Combination of G. sylvestre and P. daemia presents potent synergistic activity against hyperandrogenism, hyperinsulinemia, anovulation and follicular cysts in letrozole-induced PCOS rats.

Objective:

To characterize the semen of three genetic types of boars (local, improved and Large White) reared in Benin.

Methods:

Semen of local, improved and Large White boars reared in Benin were collected using the gloved hand method and analyzed to determine volume, pH, concentration, mobility, motility, and morphology. The effect of the genetic type of boar on semen characteristics was aslo studied.

Results:

Duration of ejaculation and semen volume of Large White boar were significantly higher than those of local and improved boars (P<0.05). The semen of improved boars had a higher motility score than that of Large White and local boars (P<0.001). The semen of local boars was more concentrated in the spermatozoa than that of improved and Large White boars (P<0.05). The proportion of spermatozoa of improved boars with normal morphology (93.6%) was significantly higher than that of local (82.2%) and Large White boars (81.6%) (P<0.001). The proportion of spermatozoa with folded tails in the semen of Large White boars (9.2%) was significantly higher than that observed in improved (1.8%) and local (5.0%) boars (P<0.001). The proportion of spermatozoa with proximal cytoplasmic droplets in semen of improved boars (2.7%) was significantly lower than that in Large White (6.8%) and local (9.7%) boars (P<0.001). The local (1.5%) and Large White boars (1.1%) showed more spermatozoa with distal cytoplasmic droplets in their semen compared to the improved boars (0.4%).

Conclusions:

The semen characteristics of pigs reared in Benin vary from one genetic type to another. Each genetic type has a strong point. The Large White boar produces larger semen, the local boar produces more concentrated semen and the improved boar produces spermatozoa that are morphologically better. The semen of these three genetic types can be used in artificial insemination but the improved boar's semen is more recommended.
Evaluation of pig oocyte in vitro maturation and fertilization using three gonadotropin-based hormonal compounds

Published: March 2021

Objective:

To evaluate the effect of human chorionic gonadotropins (hCG) and equine chorionic gonadotropins (eCG) on in vitro gilt oocyte maturation and embryonic development, using frozen semen for fertilization.

Methods:

Two independent experiments (6 replicates each) were carried out to evaluate gilt oocyte maturation, and fertilization and embryonic development by using ovaries from a local abattoir. Totally, 712 oocytes were randomly distributed in four-well dishes to receive Novormon (eCG 5.0 IU), PG600 (eCG 5.0 IU and hCG 2.5 IU), Chorulon (hCG 5.0 IU), or no hormones. Oocytes were incubated with 5% CO2, 95% air and saturation humidity at 39 °C for 44 h. Maturation of the oocytes to metaphase II was assessed by using the aceto-orcein technique. In addition, 741 oocytes were used and randomly distributed in four-well dishes, and then oocyte maturation was carried out as mentioned, but matured oocytes were washed and placed in fertilization medium with frozen-thawed sperm. Gametes were co-incubated for 7 h, and then washed and placed in development medium, and incubated for further 7 days, at which time embryonic development was evaluated. Fertilization and embryo development media were not supplemented with the studied hormones.

Results:

Novormon (eCG) and PG600 (eCG+hCG) treatments significantly improved the percentages of metaphase II oocytes compared to the control group (P<0.05). Furthermore, a significant increase was also observed in the young blastocyst stage between the control group and the PG600 treatment group (P<0.05).

Conclusions:

Hormonal products Novormon (eCG) and PG600 (eCG+hCG) can obtain the highest percentages of in vitro maturation in gilt oocytes; however, this effect is not transferred to fertilization rates.

Background:

The COVID-19 pandemic has impacted physical health, wellbeing, and mental health, which has a disastrous effect on the health system. Among disorders emerging in the aftermath of a disaster, depression is the second most common.

Aim:

The current study was aimed to estimate the prevalence of major depressive disorder (MDD) at two-time points in individuals who have been hospitalized for the treatment of COVID 19.

Materials and Methods:

A prospective study was carried out from May 2020 to October 2020 at a tertiary care center among patients discharged after recovery from novel coronavirus (COVID 19). A diagnostic clinical interview was conducted to diagnose MDD, and its severity in patients who had recovered from COVID 19 using “Patient Health Questionnaire (PHQ-9)” at the time of discharge and 1 month after their discharge from the hospital.

Statistical Analysis:

Descriptive statistics and Chi-square test were used for the analysis, P < 0.05 was considered statistically significant.

Results:

A total of 440 participants participated in the study. Out of them, 30.90% of participants met the criteria for MDD at the time of discharge and 19.5% at 1 month post-discharge. Participants who stayed for more than 14 days, were admitted to intensive care unit (ICU) and those with co-morbid medical illness had a higher prevalence of MDD.

Conclusion:

High prevalence of MDD was observed at the time of discharge among hospitalized participants. Longer duration of hospital stay and admission in ICU is associated with more unpleasant events, subsequently resulting in higher rates of morbidity, such as depression.

Adenoid cystic carcinoma (AdCC) is an aggressive neoplasm that often carries a poor prognosis due to its high recurrence rate. Due to its indolent growth, it is often overlooked by the patients and early diagnosis is often challenging due to its deceptively benign clinical course. We report a case of AdCC in the lower lip and buccal mucosa of a patient with a review of the literature and added emphasis on their diagnosis and prognosis.
