A Study on the Management of Career Development of Young Teachers in Higher Education Institutions from the Perspective of Career Anchors

In January 2021,six departments in China,including the Ministry of Education jointly issued the Guiding Opinions on Strengthening Reform in HEI Teacher Capacity Building for the New Era which emphasizes support for career development of young teachers.From the perspective of the career anchor theory,this paper takes human resource management as a tool to analyze organizational environment at the macro and micro levels to find out how to facilitate career development of young teachers in higher education institutions.

Chicory(Cichorium intybus L.) and cereals differently affect gut development in broiler chickens and young pigs

Dietary fiber, resistant to host-mediated digestion in the small intestine due to lack of endogenous enzymes, impacts many facets of animal health and is associated with gut development especially in young monogastrics. Furthermore, it can be used as in-feed antibiotic alternative. Chicory （Cichorium intybus L.） forage with high content of pectin （uronic acids as building blocks） is a novel class of dietary fiber that is chemically different from cereal grains （with high content of arabinoxylans）. In the present study, we investigated effects of dietary inclusion of chicory forage on digestibility, gut morphology and microbiota in broilers and young pigs. In the chicken experiment, 160 1-d old broiler chicks were fed 3 nutritionally balanced diets for 30 d including a cereal-based diet and 2 diets with part of the cereals substituted with 60 and 120 g/k9 chicory forage （CF60 and CF120], whereas in the pig experiment, 18 seven-wk old Yorkshire pigs were fed 3 diets for 18 d including a cereal-based diet and 2 diets with 80 and 160 g/kg chicory forage inclusion （CF80 and CF160）. Our results showed that young pigs were capable to utilize chicory forage well with higher total tract apparent digestibility （TTAD） of all fiber fractions, particularly uronic acid, compared with the control （P 〈 0.01）. In contrast, a decreased TTAD of all fiber fractions was observed in chickens fed on diet CF120 （P 〈 0.05）. Moreover, diet induced changes in gut morphology were observed in the large intestine of chickens. The alteration of cecal mucosal thickness was further positively correlated with TTAD of non-starch polysaccharides （NSP） and its constituent sugars （P 〈 0.05）. In addition, in pigs, terminal restriction fragment length polymorphism （T-RFLP） analysis of intestinal microbiota revealed substantial dietary effects （cereal control diet vs. chicory forage inclusion） on the relative abundance of 2 dominant bacterial phylotypes （Prevotella sp. vs. Roseburia sp.） respectively （P 〈 0.05）. In conclusion, our data showed that chicory forage （Cichorium intybus L.）, a novel dietary fiber source in animal nutrition, have potential beneficial properties as fiber ingredient in diets for both pigs and chickens.

Genetic and Environmental Effects on the Bone Development of the Hand and Wrist in Chinese Young Twins

We assessed genetic and environmental effectson bone development of the hand and wrist, andon key anthropometric measures in Chinese youngtwins. In total, 139 monozygotic and 95 dizygotictwin pairs aged from 5 to 18 years were recruited.The twin correlations of total hand and wrist scoresfor monozygotic （MZ） and dizygotic （DZ） twins were0.71 and 0.36, respectively. Bivariate modelanalysis showed moderate genetic correlations onlyfor total skeletal maturity vs. weight and totalskeletal maturity vs. waist circumference （r, 0.51and 0.46, respectively）. Our findings demonstratedthat genetic factors played important roles in bonedevelopment of the hand and wrist in Chineseyoung twins, and that these genetic effects mightbe distinct from those influencing anthropometricmeasures.

Twice-split phosphorus application alleviates low-temperature impacts on wheat by improved spikelet development and setting

Extreme low-temperature incidents have become more frequent and severe as climate change intensifies.In HuangHuai-Hai wheat growing area of China,the late spring coldness occurring at the jointing-booting stage(the anther interval stage)has resulted in significant yield losses of winter wheat.This study attempts to develop an economical,feasible,and efficient cultivation technique for improving the low-temperature(LT)resistance of wheat by exploring the effects of twice-split phosphorus application(TSPA)on wheat antioxidant characteristics and carbon and nitrogen metabolism physiology under LT treatment at the anther interval stage using Yannong 19 as the experimental material.The treatments consisted of traditional phosphorus application and TSPA,followed by a-4℃ LT treatment and natural temperature(NT)control at the anther interval stage.Our analyses showed that,compared with the traditional application,the TSPA increased the net photosynthetic rate(P_(n)),stomatal conductance(Gs),and transpiration rate(T_(r))of leaves and reduced the intercellular carbon dioxide concentration(C_(i)).The activity of carbon and nitrogen metabolism enzymes in the young wheat spikes was also increased by the TSPA,which promoted the accumulation of soluble sugar(SS),sucrose(SUC),soluble protein(SP),and proline(Pro)in young wheat spike and reduced the toxicity of malondialdehyde(MDA).Due to the improved organic nutrition for reproductive development,the young wheat spikes exhibited enhanced LT resistance,which reduced the sterile spikelet number(SSN)per spike by 11.8%and increased the spikelet setting rate(SSR)and final yield by 6.0 and 8.4%,respectively,compared to the traditional application.The positive effects of split phosphorus application became more pronounced when the LT treatment was prolonged.

大豆异黄酮对幼年小鼠生殖发育的影响

目的探讨大豆异黄酮(SI)对幼鼠生殖发育的影响。方法将C57BL/6幼鼠随机分为对照组和SI小、大剂量组(10、100 mg/kg),每组10只,雌雄各半。各药物组幼鼠灌胃相应药液,每天1次,持续2周。末次灌胃后,计算幼鼠的体重增长百分比,检测血清雌二醇、睾酮水平以及生殖器官组织中丙二醛(MDA)含量、总抗氧化能力(T-AOC)和超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-Px)活性,观察其生殖器官组织的病理改变,并检测其细胞凋亡情况。结果与对照组比较,SI大剂量组雌性幼鼠的体重增长百分比显著升高,而雄性幼鼠的体重增长百分比显著降低(P<0.05或P<0.01)。SI各剂量组幼鼠卵巢组织均可见囊性卵泡,睾丸组织可见精母细胞排列松散,附睾组织可见部分上皮细胞脱落。SI各剂量组雌性幼鼠血清睾酮水平和雄性幼鼠血清睾酮、雌二醇水平,SI小剂量组雌性幼鼠卵巢组织中GSH-Px活性和SI各剂量组雌性幼鼠卵巢组织中T-AOC,以及SI各剂量组雄性幼鼠睾丸及附睾组织细胞凋亡率均显著升高(P<0.05或P<0.01);SI各剂量组雌性幼鼠血清雌二醇水平,SI大剂量组雌性幼鼠卵巢组织中SOD活性和SI各剂量组雌性幼鼠卵巢组织中MDA含量,以及SI各剂量组雌性小鼠卵巢组织细胞凋亡率均显著降低(P<0.05或P<0.01)。结论SI可提高雌性幼鼠卵巢组织的抗氧化应激能力,减少其氧化应激损伤,但对雄性幼鼠的生殖器官具有一定的蓄积毒性。

喷点雪印小丑鱼的胚胎及仔、稚、幼鱼形态发育观察

为建立喷点雪印小丑鱼(Amphiprion sp.)人工繁育技术,在人工模拟自然条件下对其繁殖习性、胚胎发育及胚后发育进行观察。结果表明:喷点雪印小丑鱼受精卵长径为1.9~2.1 mm,短径为0.93~0.95 mm;胚胎发育主要经历受精卵期→胚盘期→卵裂期→囊胚期→原肠胚期→神经胚期→器官形成期→孵化期等;在水温为(27±0.5)℃时,受精卵约需197 h孵化出膜。初孵仔鱼全长(4.415±0.412)mm,身体透明,鳍膜明显,卵黄囊仅剩小部分残留,并已开口摄食。9日龄全长(6.813±0.835)mm,鳍膜消失,各鳍基本形成,头部开始出现纹带,进入稚鱼期。21日龄全长(10.581±2.659)mm,身体被鳞,体色、纹路开始分化。35日龄全长(15.512±4.927)mm,形成4种不同体色、纹路的幼鱼。作为人工选育的品系,喷点雪印小丑鱼胚后发育过程中最为明显的变化是幼鱼期体色、纹路等形态特征的形成与分化。

农村基层干部青年化对提升村民收入的影响——基于农村发展治理的分析视角

农村基层干部青年化是大势所趋,农村基层干部作为农村发展的“领头羊”肩负重大的历史使命,组织振兴是乡村振兴的目标之一,青年干部则为基层组织提供新鲜血液。为研究农村基层青年干部的富民效应,通过2021年南京农业大学的中国土地调查数据,运用计量经济学模型进行实证分析,探究农村基层干部青年率对行政村村民经济收入的影响。结果表明,农村基层干部的青年率的提升可以显著带动行政村村民收入提高,发展集体产业经济和开展村内民主治理活动对村民收入也有显著的正向影响,青年干部在农村发展社区治理上也存在不足,健康的农村基层干部年龄结构应该是有较大青年基层干部比例的同时兼具一定数量的年长基层干部,实现乡村发展治理的综合全面。
