Penelitian ini bertujuan untuk mendeskripsikan kemampuan proses matematis siswa Kalimantan Timur dalam menyelesaikan soal matematika model PISA (Programme for International Students Assessment). Penelitian ini dilakukan terhadap 300 siswa kelas IX SMP Kalimantan Timur yang belum pernah mewakili Indonesia sebagai sampel PISA bidang Matematika. Siswa tersebut tersebar dari tiga level sekolah (rendah, sedang, tinggi) yang ditentukan berdasarkan hasil Ujian Nasional 2016 pada mata pelajaran matematika. Pengumpulan data menggunakan 16 butir soal matematika model PISA (α = 0,835) yang mencakup tiga proses matematis: formulate, employ dan interpret. Kemampuan siswa dianalisis berdasarkan mean measure logit dan selanjutnya ditransformasi ke skala dan level kemampuan matematika PISA, sehingga dapat dibandingkan dengan rata-rata kemampuan siswa Indonesia dan negara OECD dalam studi PISA. Hasil analisis data menunjukkan bahwa kemampuan siswa Kalimantan Timur berada di bawah rata-rata negara OECD. Namun hasil tersebut lebih baik dibandingkan capaian skor siswa Indonesia yang menjadi sampel pada PISA 2015. Berdasarkan kemampuan dalam proses matematis, kemampuan siswa dari level tinggi ke rendah berturut-turut adalah formulate, employ dan interpret. Selain itu, kemampuan proses formulate siswa Kalimantan Timur dari sekolah kategori tinggi di atas rata-rata negara OECD. East kalimantan students’ mathematical process proficiency in solving PISA-like mathematicsAbstractThis study was aimed to describes East Kalimantan students’ mathematical processes proficiency in solving a PISA-like mathematics test. The study was carried out with 300 East Kalimantan ninth-grade students who haven’t represented Indonesia as Mathematics PISA samples. The students were spread across three school levels (low, medium, high) determined based on the results of the 2016 National Examination in mathematics. Data collection uses 16 items of PISA-like mathematics test (α = 0.835) which includes three mathematical processes: formulate, employ, and interpret. Student proficiency was analyzed based on mean measure logit and subsequently transformed to the scale and level of PISA mathematics proficiency so that it can be compared with the average proficiency of Indonesian students and OECD countries in the PISA study. The results of the data analysis show that the average proficiency of East Kalimantan students is below the average of OECD countries. However, these results are better than the average score of Indonesian students who were sampled at PISA 2015. Based on proficiency in the mathematical process, the proficiency of students from high to low levels consecutively namely: formulate, employ, and interpret. In addition, proficiency in the formulating of East Kalimantan students from high-level schools is above the average of OECD countries.

Abstract This paper demonstrates a breakthrough method of visible laser probing (VLP), including an optimized 577 nm laser microscope, visible-sensitive detector, and an ultimate-resolution gallium phosphide-based solid immersion lens on the 10 nm node, showing a 110 nm resolution. This is 2x better than what is achieved with the standard suite of probing systems using typical infrared (IR) wavelengths today. Since VLP provides a spot diameter reduction of 0.5x over IR methods, it is reasonable, based simply on geometry, to project that VLP using the 577 nm laser will meet the industry needs for laser probing for both the 10 nm and 7 nm process nodes. Based on its high level of optimization, including high resolution and specialized solid immersion lens, it is highly likely that this VLP technology will be one of the last optically-based fault isolation methods successfully used.

BACKGROUND Nonadherence to self-management is common among patients with type 2 diabetes (T2D) and often leads to severe complications. Short messages service (SMS) technology provides a practical medium for delivering content to address patients’ barriers to adherence. OBJECTIVE The aim of this study was to design a series of SMS intervention templates, and to evaluate the feasibility of the SMS through a short message quality evaluation questionnaire and to explore the intervention effect. METHODS 1. The SMS evaluation was assessed through the 10-point scale SMS Quality Assessment Questionnaire. 2. A randomized controlled trial was conducted. The patients in SMS intervention were randomly divided into intervention group (IG) and control group (CG), which received evaluated messages education and regular education, respectively. The intervention was divided into four phases, a telephone interview was conducted to evaluate the effectiveness of the intervention after each phase. The main outcome were changes in blood glucose and blood pressure (BP) and their control rates, and secondary outcomes were changes in diet, physical activity, weight control and other health-related behaviors. RESULTS 1. SMS design: 42 SMS text messages were designed to promote healthy behaviors in different stages of behavior change, covering four key domains: healthy knowledge, diet, physical activity, living habits and weight control. 2. SMS evaluation: The average score for healthy knowledge, diet, physical activity, living habits, weight control were 8.0 (SD 0.7), 8.5 (SD 0.6), 7.9 (SD 1.0), 8.0 (SD 0.7), and 8.4 (SD 0.9), respectively. 3. SMS intervention: A total of 146 people completed the four-phase intervention, including 72 in the CG and 74 in the IG. At the end of the intervention period, in the IG, the decrease in fasting blood glucose (FBG, mean 1.5mg/l [SD 3.0] vs 0.4 mg/l [SD 2.8], P=0.011), postprandial blood glucose (PBG, mean 5.8mg/l [SD 5.1] vs 4.2 mg/l [SD 4.7], P=0.028), systolic blood pressure (SBP, mean 9.1mmHg [SD 15.8] vs 2.2mmHg [SD 13.3], P=0.025), FBG control rate (45.9% vs 31.0%, P=0.046) and PBG control rate (57.8% vs 33.7%, P=0.002) were better than the CG. In self-behavior management, the changes of the weight control, diet and physical activity in the IG were better than those in the CG, and the average score of the IG was greater than that of the CG (1.1 vs [-0.3] ), P0.001). CONCLUSIONS The overall quality of SMS content is higher to meet the needs of patients; Diet, physical activity and weight control message need to be focused on push. SMS interventions contribute to the management of blood glucose and BP, and help to promote a series of healthy-related behaviors.

BACKGROUND The Copperbelt University is the second public University in Zambia. The School of Medicine has four major programs namely; Bachelor of Medicine and Surgery, Bachelor of Dental Surgery, Bachelor of Clinical Medicine and Bachelor of Biomedical sciences. The Copperbelt University School of Medicine runs a five-year training program for both the BDS and the MBCHB programs. Students are admitted into the Medical school after successfully completing their first year at the Main campus in the School of Natural Sciences with an average of 4 B grades or higher (B grade is a mark of 65 to 74%). OBJECTIVE The study was done to determine the association between admission criteria and academic performance among preclinical students. Hence, the study compares the academic performance among preclinical students admitted into the Bachelor of Dental Surgery and Bachelor of Medicine and Surgery at the Copperbelt University School of Medicine. METHODS This is a retrospective cohort study conducted at Michael Chilufya Sata School of medicine Campus. A pilot study was conducted with 30 BDS and 30 MBCHB students and the obtained information helped determine the sample size. SPSS was used to analyze the data. The study period lasted approximately 7 weeks at a cost of K1621. RESULTS In 2014, there was an improvement in average performance between 2nd and 3rd year for each program. An average score of 15.4 (SD 4.2) was obtained in 3rd year compared to 12.8 (SD 4.9) in 2nd year (p<0.001). Meanwhile, 3rd MB ChB mean score was 12.6 (SD 3.7) compared to 10.7 (SD 3.6) in 2nd years (p<0.05). However, in 2016, both programs, 3rd year mean scores were lower than 2nd year (MB ChB 2nd year mean score was 12.0 (SD 4.3) compared to 3rd year with a mean score of 9.5 (SD 4.5), p<0.001; BDS 2nd year mean score was 10.6 (SD 4.0) compared to 3rd year mean score of 8.2 (SD 3.4), p<0.01. On average MB ChB students performed better than BDS students in all the years (p<0.05), except in 2016 when the results were comparable. CONCLUSIONS Results from the study shows that entry criteria has a correlation to academic performance as students admitted with higher grades perform much better than those with lower grades.

This presentation summarizes a register-based study on women who have been identified as belonging to three violent extremist milieus in Sweden: violent Islamic, violent far-right, and violent far-left extremism. We studied the women in these milieus along a number of analytical dimensions, ranging from demographic and educational to criminal background and network relationships, and compared them to three reference groups: (i) non-extremist biological sisters to female extremists in the study population; (ii) men in the respective extremist milieus; and (iii) female members of other antagonistic milieus such as organized crime. Our results showed that there are both similarities and differences between groups. In some cases, like age and region of birth, there are commonalities between violent far-right and violent far-left women. Regarding region of birth and migration background, women affiliated to violent far-right and violent far-left extremism are predominantly born in Sweden. Women affiliated to violent Islamic extremism tend to be born in Sweden to a greater extent than men in the same milieu, but to a much lesser degree than women in the violent far-right and violent far-left. When it comes to education, women in the violent Islamic milieu are closer to women in violent far-right extremism. Women in violent far-left extremism perform best at school, with consistently higher grades. The average score of women in violent far-left extremism is identical to that of their sisters, and women in violent far-left extremism perform on average substantially better than men in the same milieu. Women in violent Islamic extremism, in contrast, perform on average similarly to men in violent far-left extremism, and they perform better than their biological sisters. Regarding labor market attachment, violent Islamic extremists have the weakest attachment and the highest dependency upon financial assistance as well as a low employment share (36 percent in 2016), but also a relatively high share of individuals with a high number of unemployment days, suggesting that women in violent Islamic extremism experience higher social exclusion. We find the highest employment share among women in violent far-left extremism, where 89 percent are gainfully employed in 2016 (80 percent for at least three of the last five years) and about a 20 percent unemployment share. Men in violent far-left extremism have an employment share around 10 percent below that of the women in far-left extremism for 2016. The highest fractions of individuals that have not been in contact with the health system due to mental disorders are among violent Islamic extremism, with the women’s fraction at 84 percent, compared to their non-extremist sisters and men in the same milieu that are just above 79 percent. Women in violent far-left extremism have the highest share of in-patient major mental disorders among the extremist milieus (3 percent), higher than men in the same milieu (less than 1 percent) as well as than women and their sisters in the other categories. During the period 2007–2016, 68 percent of individuals in the extremist milieus are covered by the register of suspected individuals. The coverage is substantially higher for men, 72 percent than for women, 43 percent. Compared to their sisters, women in all three milieus are criminally active to a much higher extent. However, women in all three milieus are less criminally active than women in other antagonistic milieus, among whom 67 percent have been suspected at least once. In all three milieus, the share of men with a criminal record is about twice as large as that of women. As far as the gender aspect is concerned, we know that extremist milieus generally have a conservative view of the role of women in society. In our results, this is reflected in the low rates of crime in women compared to men, and relatively marginal positions in the co-offending networks. The fact that women in violent far-left extremism have stronger positions in their networks than the other women in the study population is expected, given that the ideology of this milieu allows for greater equality. This means that women in violent far-left extremism participate more often than, e.g., women in violent far-right extremism, in political actions where violence is common. This pattern of gender roles and criminal involvement also holds concerning women in violent Islamic extremism. This milieu has a more traditional view of the role of women than views among even violent far-right extremists. Women in violent Islamic extremism are less involved in crime and, in particular, violent crime.

When we look at bars flashed against a moving background, we see them displaced in the direction of the upcoming motion (flash-grab illusion). It is still debated whether these motion-induced position shifts are low-level, reflexive consequences of stimulus motion or high-level compensation engaged only when the stimulus is tracked with attention. To investigate whether attention is a causal factor for this striking illusory position shift, we evaluated the flash-grab illusion in six patients with damaged attentional networks in the right hemisphere and signs of left visual neglect and six age-matched controls. With stimuli in the top, right, and bottom visual fields, neglect patients experienced the same amount of illusion as controls. However, patients showed no significant shift when the test was presented in their left hemifield, despite having equally precise judgments. Thus, paradoxically, neglect patients perceived the position of the flash more veridically in their neglected hemifield. These results suggest that impaired attentional processes can reduce the interaction between a moving background and a superimposed stationary flash, and indicate that attention is a critical factor in generating the illusory motion-induced shifts of location.

Over a 3-yr period, 1,556 lambs were produced from matings of Dorset Horn and Finnish Landrace rams to ewes of the Romnelet, Columbia, Suffolk, and North Country Cheviot breeds and their 2-, 3-, and 4-breed crosses. Also, 142 purebred lambs of the four dam breeds were produced as a basis for contemporary comparisons. The average weaning weight of the purebred lambs was 23.7 ± 0.4 kg; of the 2-breed cross lambs, ½-Dorset lambs averaged 25.1 ± 0.5 kg and ½-Finnish Landrace 25.6 ± 0.5 kg. The 3-breed cross ½-Dorset lambs averaged 27.1 ± 0.4 kg and ½-Finnish Landrace lambs 26.1 ± 0.4 kg; and 4-breed cross ½-Dorset lambs 27.1 ± 0.4 kg and ½-Finnish Landrace lambs 26.8 ± 0.4 kg. The 5-breed cross ½-Dorset and ½-Finnish Landrace lambs both averaged about 27.5 ± 0.5 kg. Weight-per-day-of-age to market weight showed the same trend as weaning weight among the purebred and crossbred lambs. Purebred lambs were exceeded by 2-breed cross lambs in weaning weight (7%) and weight-per-day-of-age to market weight (6%) and by 3-breed cross lambs (13% and 8%, respectively). No practical additional improvement for either trait was evident in 4-breed and 5-breed crosses. Two-breed cross ewes (Romnelet × Suffolk and Columbia × Suffolk) raised lambs of about the same weaning weight (27.7 and 27.3 kg) as the 3-breed and 4-breed cross ewes (24.9–27.4 kg). Dorset Horn and Finnish Landrace rams contributed about equally to weaning weights (26.6 and 26.5 kg) and weight-per-day-of-age to market weight (0.241 and 0.236 kg). The average score of the ½-Finnish Landrace carcasses was slightly, but significantly, better than that of the ½-Dorset Horn carcasses. Both Dorset Horn and Finnish Landrace rams produced crossbred lambs with satisfactory growth and carcass merit.

This paper aimed to explore the changes posed by the new COVID-19 pandemic to the field of social work and its impact on social workers in terms of job stress and burnout in Romania. Two conceptual models were used to frame the discussion: the theoretical framework of VUCA (volatility, uncertainty, complexity, and ambiguity) to discuss the challenges that the unprecedented context of the COVID-19 pandemic has created for social workers; and the Job Demands and Resources model (JD-R) to understand job demands perceived as stressors and burnout. Based on convergent mixed methods, the study sample consisted of 83 social workers employed in statutory and private social services in Romania, from different areas of intervention. Results showed that social workers perceived a high level of job stress related to work during the pandemic, which was associated with higher levels of burnout in the areas of personal burnout (average score 55.9) and work-related burnout (average score 52.5). Client-related burnout was lower (average score 38.4), indicating that stress was generated mainly by organisational factors and work-related factors (workload, aligning to new legislative rules and decisions, inconsistency, instability, ambiguity of managerial decisions, and lack of clarity of working procedures) and less by client-related stressors (lack of direct contact with clients, risk of contamination, managing beneficiaries’ fears, and difficulties related to technology). High job demands and limited job resources (managerial and supervisory support, financial resources, and recognition and reward) led to a high to very high level of work-related burnout for 15.7% and an upper-medium level for 44.2% of respondents. A group of 27.7% reported lower to medium levels of work-related burnout, while 14.5% had very low levels, managing to handle stress factors in a healthy manner. Study results pointed to the importance of organisational support and the development of a self-care plan that help to protect against job stress and burnout. Recommendations were made, putting forward the voice of fieldworkers and managers fostering initiatives and the application of sustainability-based measures and activities designed to deal with the challenges of the VUCA environment.

To achieve the sustainable development goals established by the United Nations in 2015, China has adopted a series of measures to promote the modernization of water conservancy. However, its construction in China is imbalanced across regions as the endowment of water resources and economic development are distinct. Consequently, it is important to assess the progress of and analyze the spatial heterogeneity of water conservancy modernization construction in China from the perspective of sustainable development goals (SDGs). In this study, 31 regions in China were selected, and data on water conservancy construction in these sampled regions (excluding Hong Kong, Macao, and Taiwan) were collected in 2018. The results show that there exists an imbalanced development in terms of the overall level and the index level. About 60% of the regions scored below the overall average score for China’s current modernization of water conservancy. The eastern areas presented a high level of modernization, while the central, northeast, and western areas showed comparable modernization of water conservancy, all of which lag behind eastern areas of China. Furthermore, China’s water conservancy modernization also presented a strong spatial autocorrelation, and there was at least one deficiency in 55% of the regions, with the rate of deficiencies emerging in the West being much higher than in other regions. In a nutshell, this study provides a novel framework that can be extended to evaluate the SDGs and the effectiveness of water governance in other countries.

The value judgments about medicine are contributed to by the public image. Formerly this has been one of a devoted, caring, self-sacrificing, somewhat unworldly group of people, dedicated to their work for the suffering and diseased. But the doctors are not separate from society and they are affected by its values. These have been adopted by the profession so that it is coming to be seen as no worse and no better than any other group of comparable education and training. Its status has diminished and this has called into question its compensation at a high level. Status cannot be maintained when its base has been eroded.
